One end of the cleaning slot 34 extends through the frame 1 to the outside of the frame 1 , the end extending out of the frame 1 is inclined downward, and the inclined end is communicated with the outside. The opening at the lower end of the cleaning tank 34 is provided with a separation tank 35 having an upper opening structure. The side wall of the separation tank 35 has a number of drainage holes 351 penetrating through it. The motor 23 drives the driving roller 21 to rotate, thereby using the chain mesh belt 22 to rotate, using the chain mesh belt 22 to remove the garbage from the sewage, and then using the nozzle 32 to spray water toward the chain mesh belt 22, using the impact of water to make the garbage and the chain mesh. The belt 22 is separated, and the separated garbage and the water sprayed by the nozzle 32 enter the cleaning tank 34, enter the separation tank 35 through the cleaning tank 34, and use the separation tank 35 to separate the garbage and water. At this time, the cleaning of the garbage is completed, and at the same time The gap of the chain mesh belt 22 is small, so that fine suspended matter can be separated.

As shown in FIG. 2 , when the garbage is separated from the chain mesh belt 22 by the water flow, the garbage will have a large initial velocity when it is impacted by the water flow, and the garbage will move a long distance at this time, so that the collection tank cannot The garbage is collected completely, causing the garbage to move into the treated water, which affects the cleaning effect of the garbage. Therefore, the frame 1 is connected with two guide rollers 24 for guiding the mesh belt 22 . The other guide roller 24 is in contact with the outer wall of the chain mesh belt 22 and is higher than the driving roller 21 in the sewage. The chain mesh belt 22 located between the two guide rollers 24 is arranged horizontally, and the nozzles of the nozzles 32 are oriented in a direction. On the upper end of the horizontal chain mesh belt 22 , the cleaning groove 34 is located at the lower end of the horizontal chain mesh belt 22 , and its opening faces the horizontal chain mesh belt 22 . At this time, after the garbage is driven by the chain mesh belt 22 and passes through the driving roller 21 located above, the garbage automatically enters the cleaning tank 34 under the action of gravity, and the garbage adhering to the chain mesh belt 22 is sprayed by the water sprayed by the nozzle 32. Under the action of the applied force, it is separated from the connection with the chain mesh belt 22 and enters the cleaning tank 34.

The garbage is hooked by the cleaning block 221, so that the chain mesh belt 22 can drive the garbage to move together, so that the garbage will not accumulate on the end of the chain mesh belt 22 that faces the flow of sewage.

As shown in FIG. 3 , since the wedge-shaped surface 222 is inclined to the plane of the chain mesh belt 22 to which it is connected, at this time, if the water flow sprayed by the nozzle 32 is perpendicular to the chain mesh belt 22 arranged horizontally, it will cause that the garbage cannot be completely mixed with the chain mesh belt 22 . The cleaning block 221 is disengaged. Therefore, the axis of the nozzle of the nozzle 32 is parallel to the wedge-shaped surface 222 of the cleaning block 221 connected to the chain mesh belt 22 in the horizontal state. At this time, the flow direction of the water sprayed by the nozzle 32 is parallel to the wedge-shaped surface 222, so that the garbage adhering to the surface of the cleaning block 221 is more easily separated from the cleaning block 221, so that the surface of the cleaning block 221 is not easy to adhere to the garbage, thereby reducing the garbage entering the treated in water.

As shown in FIG. 3 , since the garbage entering the separation tank 35 will contain a large amount of water, if the garbage is directly transferred at this time, the water in the garbage will enter the soil, thereby polluting the soil.

The dewatering plate 41 is placed in the separation groove 35 and slides, and its moving direction is parallel to the axis of the driving roller 21 , and its side walls are in contact with the inner wall of the separation groove 35 respectively. The cylinder block of the dehydration cylinder 42 is fixed to the end face of the separation groove 35 close to the frame 1 by bolts, and its piston rod passes through the separation groove 35 and abuts the end face of the dehydration plate 41 close to the frame 1. The air compressor is connected to the dehydration cylinder 42 . The dewatering cylinder 42 is used to push the dewatering plate 41 to move, and the garbage placed in the separation tank 35 is squeezed to separate the garbage from the water. At this time, the garbage can be moved for another treatment. At this time, the sewage will not enter the soil, so as to prevent the garbage from entering the soil. will pollute the soil.

As shown in FIG. 3 , since the garbage and water are separated by the dewatering mechanism 4 and then the garbage is transferred from the separation tank 35, the water in the cleaning tank 34 cannot enter the separation tank 35. At this time, it is necessary to make the grid The grid machine stops working, which will reduce the efficiency of waste separation. Therefore, the opening at the lower end of the cleaning tank 34 is rotatably connected with a baffle plate 36 that closes it. When dewatering the garbage in the separation tank 35, the baffle plate 36 is rotated to close the opening of the cleaning tank 34 at the lower position. At this time, the garbage can be accumulated in the cleaning tank 34, and it is no longer necessary to stop the grid machine. , so that the efficiency of garbage separation remains stable.

As shown in FIG. 3 , when the baffle 36 is used to close the opening at the lower end of the cleaning tank 34 , the baffle 36 will be subjected to the pressure exerted by water and garbage, and at this time, more effort is required to adjust the position of the baffle 36 . Keep it fixed. Therefore, the side wall of the cleaning tank 34 is connected with a driving cylinder 37 for driving the baffle 36 to rotate. The baffle 36 is driven by the driving cylinder 37 , so that it is no longer necessary to manually rotate the baffle 36 and limit the position of the baffle 36 , thereby making the use of the baffle 36 more convenient.

As shown in FIG. 3 , when the garbage is removed from the separation tank 35 , it is necessary to manually transfer the garbage from the upper end of the separation tank 35 , and the opening of the upper end of the separation tank 35 is small, so it is troublesome to directly move the garbage. Therefore, the end face of the separation tank 35 away from the dehydration cylinder 42 runs through a discharge hole 352 that communicates with its inner cavity. Closed stripper plate 38. The two side walls of the discharge hole 352 in the vertical direction are provided with sliding grooves 353. The sliding grooves 353 penetrate through the upper end surface of the separation groove 35. When it is necessary to take out the garbage from the separation tank 35, the unloading plate 38 is moved upward, and then the dewatering plate 41 is used to separate the garbage from the separation tank 35 through the unloading hole 352, and it is no longer necessary to manually take out the garbage, so that the garbage can be disposed of. The process is more convenient.

working principle:

When the garbage in the sewage is separated, the motor 23 drives the driving roller 21 to rotate, so that the chain mesh belt 22 rotates, and the chain mesh belt 22 and the cleaning block 221 are used to separate the garbage from the sewage, and the sewage passes through the chain mesh belt 22. Keep moving. After the garbage passes over the driving roller 21 at the uppermost end, it enters the cleaning tank 34 under the action of gravity. Part of the garbage is attached to the cleaning block 221 and cannot be separated from the cleaning block 221 under the action of gravity. The force is applied to disengage the garbage and the cleaning block 221 into the cleaning slot 34 . At this time, the water and garbage in the cleaning tank 34 enter the separation tank 35 simultaneously under the action of gravity. When the garbage in the separation tank 35 accumulates to the opening of the upper end of the separation tank 35, the driving cylinder 37 is used to rotate the baffle plate 36 to remove The opening of the cleaning tank 34 at the lower end is closed, and then the dewatering cylinder 42 is used to push the dewatering plate 41 to move, and the dewatering plate 41 is used to compress the garbage to separate the water from the garbage. The separated water is dispensed through the water distribution hole, and then the discharge plate is moved upward. 38. Use the dewatering plate 41 to push the garbage out of the separation tank 35. At this time, the garbage can be transferred, and then the dewatering plate 41 and the unloading plate 38 are reset, so that the baffle 36 no longer closes the opening of the lower end of the cleaning tank 34. At this point, you can continue to clean up the garbage.
