Referring to fig. 1 and 2 together, the present invention provides a wastewater back-flushing-free filter 10, the wastewater back-flushing-free filter 10 comprising: a filter box 100, a filter mechanism 200, and a drainage mechanism 300.

The filter tank 100 has a hollow rectangular parallelepiped structure, and the filter mechanism 200 is provided in the filter tank 100 to divide the interior of the filter tank 100 into the drain chamber 101 and the inlet chamber 102. The bottom of the filter box 100 is provided with a water inlet 103 and two sewage outlets 104, and the two sewage outlets 104 are respectively arranged at two sides of the water inlet 103. The water inlet 103 and the two sewage outlets 104 are communicated with the water inlet cavity 102. The filter box 100 is provided with a water inlet valve 110 at the water inlet 103, and the filter box 100 is provided with a sewage draining valve 120 at the sewage draining outlet 104. The top of the filter box 100 is opened with a water outlet 105, and the filter box 100 is provided with a water outlet valve 130 at the water outlet 105. The drain port 105 communicates with the drain chamber 101. In one embodiment, the top of the filter box 100 is opened with an exhaust port 106, and the filter box 100 is provided with an exhaust valve 140 at the exhaust port 106.

The filter mechanism 200 includes two connection plates 210, a barrel support 220, and a filter sleeve 230. The open end of the barrel support 220 is connected to the inner wall of the filter box 100 by two connection plates 210. The filter sleeve 230 is sleeved on the barrel-shaped support frame 220. The open end of the barrel support 220 faces the water inlet 103. In this embodiment, the filter sleeve 230 is a melt blown filter element.

The flow guiding mechanism 300 is disposed in the filter box 100, and the flow guiding mechanism 300 includes a receiving column 310, two connecting stages 320, and two limit baffles 330. Each end of the receiving column 310 is connected with an inner side wall of the filter box 100, two connecting platforms 320 are symmetrically arranged at two sides of the water inlet 103, and two limit baffles 330 are symmetrically arranged in the filter box 100. One side of each limit stop 330 is rotatably connected to a connecting table 320. In this embodiment, the cross-section of the connection table 320 is trapezoidal so that the waste water mixed with the silt is discharged out of the filter box 100 through the drain 104. Further, the cross section of the connecting table 320 is a right trapezoid, and the right-angle sides of the two connecting tables 320 are arranged close to each other. In another embodiment, the cross-section of the connecting stage 320 is an isosceles trapezoid. One surface of the limiting baffle 330 can abut against the barrel-shaped supporting frame 220, and the other surface of the limiting baffle 330 can abut against the receiving column 310. When one side of the position-limiting baffle 330 abuts against the barrel-shaped supporting frame 220, the position-limiting baffle 330 rotates due to the action of gravity and finally abuts against the receiving column 310. When the two limit baffles 330 are abutted on the receiving column 310, the two limit baffles 330 are abutted.

In order to increase the sealing performance when the two position-limiting baffles 330 abut against each other, in one embodiment, a soft sealing strip is disposed on one side of the position-limiting baffles 330 away from the connecting table 320. When the two limit baffles 330 are abutted, the soft sealing strips on the two limit baffles 330 are abutted. Specifically, in this embodiment, the soft sealing strip is a soft rubber strip, and the soft rubber strip has a certain elasticity, good toughness, and excellent corrosion and wear resistance. In another embodiment, the soft sealing strip is a soft silicone strip. In another embodiment, the flexible sealing strip is a flexible plastic strip. Thus, the soft seal strip disposed on the side of the position-limiting baffle 330 away from the connecting table 320 increases the sealing performance when the two position-limiting baffles 330 are abutted.

In the operation of the wastewater back-flushing-free filter 10, the water inlet valve 110 and the water discharge valve 130 are opened, and wastewater containing a large amount of silt enters the filter tank 100 through the water inlet 103. Under the impact force of the waste water, the two limit baffles 330 rotate and are far away from each other, the waste water containing a large amount of silt enters the water inlet cavity 102 and enters the barrel-shaped support frame 220, and after being filtered by the filter sleeve 230, the clean water enters the drainage cavity 101 and is discharged out of the filter box 100 through the drainage port 105. When the sediment on the inner wall of the filter sleeve 230 is excessive as the filtering operation is performed, the water inlet valve 110 is closed and the drain valve 120 is opened. Due to the action of gravity, the limiting baffles 330 can rotate and finally abut against the receiving column 310, and when the two limiting baffles 330 abut against the receiving column 310, the two limiting baffles 330 abut against each other to close the water inlet 103. Fresh water in the drain chamber 101 passes through the filter sleeve 230 and into the inlet chamber 102. In this process, the clean water washes away the silt on the inner wall of the filter sleeve 230, and the water mixed with a large amount of silt flows between each limit baffle 330 and a connecting plate 210 and is discharged out of the filter box 100 through the two sewage outlets 104, thereby realizing the cleaning of the wastewater without backflushing the filter 10. The wastewater back-flushing-free filter 10 does not waste a large amount of water resources when the filtering equipment is frequently and precisely flushed, and is energy-saving and environment-friendly.
