Detailed Description

The technical solution in the embodiments of the present invention is clearly and completely described below with reference to fig. 1 to 6 of the present invention, but the scope of the present invention is not limited to the following description.

A precision filter for producing barreled water comprises a filter box 100 and three filter screens 110, wherein the three filter screens 110 are sequentially and horizontally arranged in the filter box 100 from top to bottom, the mesh apertures of the three filter screens 110 are gradually reduced from top to bottom, a water inlet pipe 120 is arranged at the top of the filter box 100, and a first water outlet pipe 130 is arranged at the bottom of the filter box 100; the top of the filter box 100 is also provided with a second water outlet pipe 140; the bottom of each filter screen 110 is horizontally provided with an annular water pipe 150, the annular water pipe 150 surrounds the inner wall of the filter box 100, each annular water pipe 150 is provided with a plurality of spray heads 160, and the spray heads 160 are arranged towards the filter screen 110 above; each annular water pipe 150 is communicated with a first water pipe 170, one end of each first water pipe 170, which is far away from the annular water pipe 150, penetrates through the side wall of the filter box 100 and is communicated with a second water pipe 290 arranged outside the filter box 100, the second water pipe 290 is communicated with a water pump 180, the water pump 180 is communicated with a water tank 190, and one end of a first water outlet pipe 130, which is far away from the filter box 100, is communicated with the water tank 190; the outer walls of the two sides of the filter box 100 are rotatably connected with cross rods 200, and vertical rods 210 are arranged at one ends, far away from the filter box 100, of the two cross rods 200.

In specific implementation, sewage to be filtered is introduced into the filter box 100 along the water inlet pipe 120, the sewage entering the filter box 100 can sequentially penetrate through the three filter screens 110, and the aperture of the filter holes of the three filter screens 110 is gradually reduced from top to bottom, so that large-volume impurities can be blocked on the uppermost filter screen 110, medium-volume impurities can be blocked on the middle filter screen 110, small impurities can be blocked on the lowermost filter screen 110, and after the sewage is filtered by the three filter screens 110, the purpose of filtering the impurities with different particle sizes can be achieved, and the purpose of fine filtering is further achieved; the purified water passing through the three layers of filter screens 110 flows to the water tank 190 along the first water outlet pipe 130 for collection, so as to realize the purpose of filtering sewage; in the filtering process, because the impurities of the sewage are gradually deposited on the three filtering nets 110, the filtering of the filtering nets 110 is slowed, the filtering efficiency is affected, the filtering nets 110 need to be cleaned, before the cleaning, the introduction of the sewage into the filtering box 100 needs to be suspended, the filtered purified water is completely discharged into the water tank 190, then the water inlet pipe 120 is blocked by a blocking device, the blocking device can select a cover or a valve, and the like, the filtering box 100 rotates around the cross rod 200, when the water inlet pipe 120 rotates downwards, the water pump 180 is turned on, so that the water in the water tank 190 flows to the plurality of nozzles 160 along the water pump 180, the second water pipe 290, the three first water pipes 170 and the three annular water pipes 150 in sequence, and finally is sprayed to the corresponding filtering nets 110 along the plurality of nozzles 160, under the back-flushing effect of the nozzles 160, the impurities blocked on the three filtering nets 110 are communicated with the back-flushing water and flushed, the washing water and the impurities on the upper filter screen 110 enter the lower filter screen 110 step by step, finally fall to the top wall of the filter box 100 and are discharged along the second water outlet pipe 140, and after the washing is finished, the filter box 100 is turned over and the filtering operation can be continued; through the back flush effect, can clear up and wash the filter screen 110 of jam under the condition of not dismantling filter screen 110, reduce staff's work load, and the operation is very simple, can greatly practice thrift the washing time, and then improve filtration efficiency. In the back flush operation process, in order to use water wisely, preferably adopt the precedence order to wash, wash earlier and be located the filter screen 110 of the top, after it washes totally, wash the filter screen 110 of below again, so operate, can avoid the filter screen 110 of below to wash totally, the washing water and the impurity of top continue the whereabouts, lead to washing the filter screen 110 of below again, and then extravagant a large amount of water resources.

Further, the three filter screens 110 are all arranged in an arc shape, and the arc surface faces upwards. The arc setting can increase the area of contact of sewage and filter screen 110, and then accelerates filtration efficiency, reduces filter screen 110's deposition rate.

Further, each first water pipe 170 is screw-coupled to a sidewall of the filter tank 100. The threaded connection facilitates the detachment and replacement of the first water pipe 170, improving the convenience of operation.

Further, vertical chute 230 has all been seted up to the both sides inner wall of rose box 100, and sliding connection has slider 220 in vertical chute 230, and three filter screens 110 and three annular water pipe 150 all set up in the relative one side of two sliders 220. The two sliding blocks 220 can freely slide in the two vertical sliding grooves 230; through making three filter screens 110 and three annular water pipe 150 set up in two slider 220 opposite sides, can make three filter screens 110 and three annular water pipe 150 slide in vertical spout 230 along with slider 220 synchronization, and then be convenient for take out three filter screens 110 and annular water pipe 150 to change when filter screen 110 and annular water pipe 150 damage.

Furthermore, an insertion block 240 is arranged at the contact position of each filter screen 110 and the sliding block 220, and a slot 250 matched with the sliding block 220 is horizontally arranged on the sliding block in a penetrating manner. After the sliding block 220 slides out of the vertical sliding groove 230, the filter screen 110 can be freely detached by taking the inserting block 240 out of the inserting groove 250, so that convenience is improved; meanwhile, the insertion block 240 is matched with the insertion slot 250, so that the stability of the filter screen 110 in the filter box 100 can be improved.

Further, a cover 260 is disposed on the top of the filter box 100, and the first outlet pipe 130 and the second outlet pipe 140 are disposed on the cover 260. The cover 260 is provided to facilitate the removal of the slider 220 from the vertical chute 230 and the replacement of the filter net 110 and the annular water pipe 150.

Further, an annular groove 270 is formed in the bottom surface of the box cover 260, an annular block 280 is arranged on the top periphery of the filter box 100, and the annular block 280 is inserted into the annular groove 270. By inserting the ring block 280 into the ring groove 270, the sealing between the tank cover 260 and the filter tank 100 can be improved, and the sewage can be prevented from flowing out along the gap between the tank cover 260 and the filter tank 100 when performing the backwashing operation.

Further, each first water pipe is provided with a valve 300. The sequence of the water outlet of the three first water pipes 170 can be controlled through the control valve 300, the water outlet speed of the three first water pipes 170 can be controlled, and convenience and flexibility are improved.
