Specific implementation

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0031] Embodiment 1, please refer to Figure 1 - Figure 4 The utility model provides a technical scheme: a kind of box type sewage filtering device, including box 1, the inner wall both sides of box 1 are fixedly connected with guide plate 107, the inner wall both sides of box 1 are fixedly connected with arc plate 108, the inner wall both sides of box 1 are movably connected with cylinder 109, the outer surface of cylinder 109 is fixedly connected with multiple paddle plates 110, one end of cylinder 109 is fixedly connected with rotating column one 103, the outer surface of rotating column one 103 is connected with belt 104 by belt pulley, the inner wall both sides of box 1 are movably connected with reciprocating threaded rod 111, one end of reciprocating threaded rod 111 is fixedly connected with rotating column two 105, the inner wall side of belt 104 is connected on the outer surface of rotating column two 105 by belt pulley, the inner wall both sides of box 1 are fixedly connected with limit column 113, the outer surface of reciprocating threaded rod 111 is threadedly connected with scraper 112, the inside of scraper 112 is movably sleeved on the outer surface of limit column 113, the inner wall both sides of box 1 are movably embedded with filter screen plate 114.

[0032] In this embodiment, one end of the inlet pipe 101 is first connected to the outlet of the sewage pipe. Then, the adjustable valve 102 is manually rotated to slightly open or close its internal opening, allowing sewage to flow out without completely filling the tank 1. The sewage gradually flows through the guide plate 107, and the water flow difference generated by the guide plate 107 flows towards the surface of the paddle plate 110. The water flow drives multiple paddle plates 110 to rotate. At the same time, the cylinder 109 drives the rotating column one 103 to rotate, the rotating column one 103 drives the belt 104 to rotate, and the belt 104 drives the rotating column two 105 to rotate forward. While the rotating column two 105 rotates forward, it drives the reciprocating threaded rod 111 to rotate continuously. At this time, the sewage passes through the filter screen 114 to filter solid impurities. While the reciprocating threaded rod 111 rotates continuously, it drives the scraper 112 to reciprocate on the surface of the filter screen 114, repeatedly pushing away the solid impurities blocking the filter screen 114. The limiting post 113 limits the scraper 112 to prevent it from spinning freely, thereby preventing the filter screen 114 from clogging. After being filtered by the filter screen 114, the sewage flows to the drain pipe 106 and is discharged through the drain pipe 106. This achieves the effect of using the force generated by the sewage flow to prevent the coarser impurities on the filter components from clogging, thus improving the filtration effect and the overall efficiency of the box-type sewage filtration.

[0033] Example 2, as Figure 1 - Figure 4 As shown, two 202s are threadedly connected to one side of the outer surface of the box 1. One end of each 202 is threadedly connected to the inside of the filter screen 114. A hand crank 203 is fixedly connected to one end of each 202. A drain pipe 106 is fixedly embedded at the bottom of the box 1 near the edge. A water inlet pipe 101 is fixedly embedded at the top of the box 1 near the edge. An adjustable valve 102 is fixedly installed on the outer surface of the water inlet pipe 101. A sealing door 2 is connected to the other side of the outer surface of the box 1 via a hinge. A handle 201 is fixedly connected to one side of the outer surface of the sealing door 2.

[0034] In this embodiment, when the filter screen 114 needs to be replaced, the operator manually rotates the hand crank 203 in sequence. The hand crank 203 begins to reverse, which drives 202 to reverse as well. As 202 reverses, it is gradually removed from the inside of the filter screen 114. Then, the operator opens the sealing door 2, pulls out the filter screen 114 as a whole for replacement, closes the sealing door 2, and manually rotates the hand crank 203 clockwise. As the hand crank 203 rotates clockwise, it drives 202 to rotate and gradually allows 202 to enter the filter screen 114, where it is locked in place. This allows for quick replacement of the filter components and improves the practicality of the box-type sewage filtration device.

[0035] Working principle: in use, first, one end of the water inlet pipe 101 is connected to the sewage pipe outlet, then manually rotate the adjustable valve 102, the opening of the adjustable valve 102 is opened a little, the sewage flows out, but the box 1 is not filled, the sewage gradually flows through the guide plate 107, the water flow difference generated by the guide plate 107 flows to the surface of the paddle plate 110, the water flow drives the plurality of paddle plates 110 to rotate, the cylindrical 109 drives the rotating column one 103 to rotate, the rotating column one 103 drives the belt 104 to rotate, the belt 104 drives the rotating column two 105 to rotate, the rotating column two 105 rotates at the same time drives the reciprocating screw rod 111 to rotate continuously, at this time the sewage passes through the filter screen plate 114 to filter the solid impurities, the reciprocating screw rod 111 rotates continuously at the same time drives the scraper 112 to reciprocate on the surface of the filter screen plate 114, the solid impurities blocked in the filter screen plate 114 are reciprocally removed, the limiting column 113 limits the scraper 112 to prevent idling, so as to prevent the filter screen plate 114 from being blocked, the sewage filtered by the filter screen plate 114 flows to the drain pipe 106, and is discharged by the drain pipe 106, so as to achieve the effect that the force generated by the sewage flow can prevent the thicker impurities on the filter assembly from being blocked, avoid the filter assembly from being blocked, improve the filtering effect, improve the overall efficiency of the box type sewage filtration, and when the filter screen plate 114 needs to be replaced, the worker manually rotates the hand crank 203 in turn, the hand crank 203 starts to reverse, the hand crank 203 drives the 202 to reverse, the 202 reverses at the same time and is gradually taken out from the inside of the filter screen plate 114, then the worker opens the sealing door 2, takes out and replaces the filter screen plate 114 in its entirety, then closes the sealing door 2, and manually rotates the hand crank 203 to rotate, the hand crank 203 rotates at the same time drives the 202 to rotate and gradually makes the 202 enter the filter screen plate 114, buckles it, so as to achieve the effect that the filter assembly can be quickly replaced, improve the practicability of the box type sewage filtration device.
