Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a quartz sand filter for water treatment. Background Art

[0002] The quartz sand filter is a high-efficiency filtration equipment that uses quartz sand as the filter medium to filter water with high turbidity through quartz sand of a certain thickness, effectively intercepting and removing suspended matter and other particles in the water, ultimately achieving the effect of reducing water turbidity and purifying water quality.

[0003] The existing quartz sand filter has some problems in use;

[0004] Since the water entering from the water inlet pipe has a large impact force, it is easy to flush the quartz sand to the surroundings, which reduces the filtering effect of the quartz sand on water. In addition, the impurities in the water are easy to cause blockage inside after being filtered by the quartz sand, which is difficult to clean. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a quartz sand filter for water treatment, which overcomes the shortcomings of the existing technology and effectively solves the problems in the existing technology that the water impact force is large, which easily washes the quartz sand around, reducing the filtering effect of the quartz sand on water, and the impurities in the water are easily blocked inside after being filtered by the quartz sand, making it difficult to clean.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A quartz sand filter for water treatment comprises a cylinder, the top of which is connected to a buffer mechanism, and the buffer mechanism comprises a cover plate, a water inlet pipe plugged and fixed to the top of the cover plate, a water inlet hopper fixed to the bottom of the cover plate, fixing rods fixed to the bottom of the water inlet hopper in a ring shape and at equal distances, and a buffer cone fixed to the bottom of the fixing rods; a filtering mechanism is provided below the buffer mechanism, and the filtering mechanism comprises a T-tube, a placement ring sleeved on the outer wall of the T-tube, a sieve ring fixed to the bottom of the inner wall around the T-tube, a fixing ring provided above the sieve ring, a connecting ring provided above the fixing ring, and a filtering ring provided between the fixing ring and the connecting ring.

[0008] The water flows into the water inlet hopper through the water inlet pipe and washes on the top of the buffer cone. The buffer cone separates the water flow and makes the water flow into the filter mechanism from all sides. Under the guidance of the drainage ring, the water flows into the quartz sand in the T-tube for filtration. When the water flows through the filter ring, the filter ring filters the large volume of impurities in the water and then enters the quartz sand for filtration again. When cleaning, the T-tube is removed from the placement ring, and the block is inserted along the slot by holding the handle. The filter ring can be pulled out of the fixed ring and the connecting ring, and the quartz sand on the top of the filter ring and the screen ring can be cleaned.

[0009] Preferably, a water outlet pipe is fixedly connected to the bottom of the cylinder, and supporting legs distributed at equal distances are fixed to the bottom of the cylinder. Grooves distributed at equal distances are opened on the top of the cylinder, and the outer diameter of the top of the water inlet bucket is adapted to the inner diameter of the cylinder.

[0010] The filtered water is discharged from the cylinder through the water outlet pipe, and the water inlet bucket is inserted into the cylinder so that the buffer mechanism is connected to the top of the cylinder.

[0011] Preferably, positioning blocks distributed at equal distances are fixed around the annular outer wall of the water inlet hopper, and the positioning blocks are plug-fitted into the grooves.

[0012] The connection between the buffer mechanism and the cylinder is positioned by inserting the positioning block into the groove.

[0013] Preferably, the outer wall of the placement ring is fixedly connected to the inner wall of the cylinder, and the top of the T-tube is connected to a drainage ring.

[0014] The T-tube is supported and placed by the placement ring, and the water flow in the cylinder is guided by the drainage ring.

[0015] Preferably, quartz sand placed on top of the sieve ring is laid in the T-tube.

[0016] Impurities in the water are filtered through quartz sand.

[0017] Preferably, the fixing ring and the connecting ring are both connected and fixed to the inner walls of the T-shaped tube, and slots distributed at equal distances are provided on the top of the connecting ring.

[0018] The filter ring is supported and placed by the fixing ring and the connecting ring.

[0019] Preferably, handles are fixed on both sides of the top of the filter ring, and clamping blocks are fixed around the annular outer wall of the filter ring, and the clamping blocks are plug-fitted into the slots.

[0020] By holding the handle and inserting the clamping block along the slot, the filter ring can be moved in and out of the fixing ring and the connecting ring.

[0021] The beneficial effects of the utility model are:

[0022] The water flows into the water inlet hopper through the water inlet pipe and washes on the top of the buffer cone. The buffer cone separates the water flow and makes it flow into the filter mechanism from all sides. When cleaning, the T-tube is removed from the placement ring, and the block is inserted along the slot by holding the handle, so that the filter ring can be pulled out of the fixed ring and the connecting ring, and the quartz sand on the top of the filter ring and the sieve ring can be cleaned. This effectively solves the problem in the prior art that the water impact force is large, and the quartz sand is easily washed around, which reduces the filtering effect of the quartz sand on the water, and the impurities in the water are easily blocked inside after being filtered by the quartz sand, making it inconvenient to clean.

The annular outer wall of the water inlet bucket 7 is fixed with equidistantly distributed positioning blocks 8. The positioning blocks 8 are plugged into the grooves to form a plug-in fit. The connection between the buffer mechanism 4 and the cylinder 1 is positioned by plugging the positioning blocks 8 into the grooves.

[0033] The outer wall of the placement ring 13 is connected and fixed to the inner wall of the cylinder 1, and a drainage ring 14 is connected to the top of the T-tube 12. The T-tube 12 is supported and placed by the placement ring 13, and the water flow in the cylinder 1 is guided by the drainage ring 14. Quartz sand placed on the top of the sieve ring 15 is laid in the T-tube 12, and impurities in the water are filtered by the quartz sand. The fixing ring 16 and the connecting ring 17 are both connected and fixed to the inner walls of the T-tube 12. Slots distributed at equal distances are provided on the top of the connecting ring 17.
