The swimming pool filter sand tank is a commonly used filter equipment, sometimes we also call it the swimming pool filter sand tank, or the swimming pool filter tank. It is a necessary procedure in the process of swimming pool circulating water treatment. The swimming pool sand filter tank is made of stainless steel.
Equipped with filter material and sand tank head, it can filter the water flowing through the tank. The filter material in the filter sand tank can be quartz sand, activated carbon, biochemical filter material and so on. 1. Specifications and types of swimming pool sand filter tanks Swimming pool sand filter tanks are mainly divided into top-out sand filter tanks, side-out type sand filter tanks and horizontal sand filter tanks.
The specific use options can be selected and decided according to the swimming pool circulating water treatment system. Below we will introduce the advantages of these three filter sand tanks in detail. 1. Top-out type filter sand tank The top-out type sand filter tank is top-mounted, that is, the switching valve is installed on the top of the sand tank, and it is made of stainless steel.
The filter sand tank is widely used in swimming pools, garden ponds, massage pools and similar public pools for swimming pool circulating water treatment and filtration. Working principle: The top-out type filter sand tank uses filter sand to remove suspended fine dirt in the pool water. As the medium for removing dirt, the filter sand is filled in the cylinder body of the filter sand tank. When the multiple valves are switched to the "filter" position, the pool water with suspended dirt in the pool is pressed into the filter pipe by the water pump. In the process, it enters the tank through multiple valves, and the fine suspended dirt is filtered out by the sand bed in the tank.
The filtered pool water enters the middle pipe through the filter claws, and then passes through a number of valve outlets and returns to the pool through the pipeline. filter. 2. Side outlet sand filter tank The side outlet sand filter tank is produced with the latest swimming pool filtration system technology, which is suitable for use in different weather conditions and meets the standards of different markets. The product features are durable, anti-corrosion, anti-ultraviolet and easy to operate, suitable for different landscape pools or swimming pool circulating water treatment.
Provides high performance filtration for your swimming pool as it has a deeper filter layer for better filtration. 3. Horizontal sand filter tank The horizontal sand filter tank is made of stainless steel. Filter out better quality water with larger filter capacity.
The turbidity and pollution index of the filtered water will be reduced by increasing the storage capacity of the filter sand tank. The time between backwashing increases correspondingly according to the height of the filter sand tank bed, that is, the continuous time in the filtration process decreases, and the water consumption also decreases, because the number of times required for backwashing is reduced, thereby reducing the impact on the filter material. of corrosion. Whether it is a place that needs to filter a large amount of water or a place with limited space, a horizontal sand filter tank is an ideal choice, because a horizontal sand filter tank can reach 3 equal diameters by simply increasing its length. The function of the vertical sand filter cylinder.
2. Installation of the swimming pool sand filter tank The installation and maintenance of the swimming pool sand filter tank is very easy, all you need is a screwdriver, wrench and sealing tape for sealing plastic joints. 1. The swimming pool sand filter tank should be placed on concrete or a solid ground with comparable hardness. The location of other equipment swimming pool sand filter tanks is convenient for the connection of pipelines, the operation of the control switch and the maintenance of the swimming pool sand filter tank. 2. Filling of the filter material, the filter material should be filled from the upper opening of the swimming pool filter sand tank.
a. Loosen the nut, and finally remove the sand filter tank from the swimming pool; b. Cover the mouth of the plastic pipe with a plastic protective cover to prevent the filter material from entering; c. Before filling the filter material, we need to fill the pool 1/2 of clean water is written into the cavity of the filter sand cylinder, which acts as a buffer and avoids excessive impact on the internal equipment when the filter material is put in. d. Fill the filter material with the correct level and weight according to the requirements (when filling, the intermediate tube must be placed stably in the middle of the cavity, and the nozzle should be covered with a protective cover), the surface of the filter material should be in the middle of the filter cavity, Then remove the protective cover. 3. Connect the initial device of the control to the sand filter tank of the swimming pool.
a. Put the control switch (with sealing ring) into the upper port of the sand filter tank of the swimming pool. Note that it is necessary to align and insert the middle pipe in the sand filter tank of the swimming pool with the hole at the bottom of the switch; b. Tighten it with a wrench Screw cap to connect the end to the pool sand filter tank. c. Install the pressure gauge (with sealing ring) on the screw hole of the switch body, do not overtighten; d. Connect the pipeline of the switch swimming pool with the nozzle marked "PUMP" at the beginning and the water pump. 4. The pipeline returning to the swimming pool is connected to the nozzle marked "RETURN" at the beginning, and the other two items are the equipment for the water pump suction pipeline and the sewage pipeline of the swimming pool filter sand tank.
5. The connection of the water pump power supply system. 6. Check the firmness and tightness of the pipeline connection, and no leakage is allowed. 3. Matters needing attention when installing the swimming pool filter sand tank 1. The PVC pipes connected to the water inlet and outlet must be supported by brackets.
Otherwise, once the water is passed through, the weight of the PVC pipe will increase and sink, which will cause the union to be twisted and broken. 2. There is a problem with the handle of the sand tank head of the swimming pool circulating water treatment filter sand tank. The plastic handle itself has a mechanical strength, and a force exceeding this strength will inevitably cause it to break.
The stable operation of the equipment requires careful maintenance. Therefore, the broken handle caused by rough construction will greatly affect the normal operation of the swimming pool circulating water treatment filter sand tank. 3. When the pressure reaches a certain level, it can be backwashed. Therefore, it is necessary to ensure that the water inlet pressure of the filter sand tank cannot exceed 3.5MPa. If the front end is connected to an engineering plastic water pump, the lift of the water pump cannot exceed 35 meters.
4. The problem of water leakage from the sand cylinder head. When loading sand, try to ensure that the sand does not fall into the gap of the multi-way valve of the sand tank head, so as to prevent the sand from entering the inside of the sealing ring to wear the sealing ring or affect the sealing. 5. Determine the location of the water distributor.
After the new sand tank is unsealed, there will be a plastic fixing frame placed at the mouth of the sand tank (take the ejection filter sand tank as an example). First use it to fix the water distributor at the center of the mouth of the sand tank, and then pour sand into the sand tank through the mouth of the sand tank. Quartz sand is usually only installed to two-thirds of the capacity of the entire sand tank.
Then clean the residual sand on the mouth of the sand tank, put the head of the sand tank according to the corresponding position of the screw hole, and reinforce it with nuts.
