Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, in particular to a kind of urban sewage deep treatment equipment and treatment process. Background Art

[0002] With the development of urbanization, domestic sewage and industrial sewage are also increasing. Preventing sewage and pollutants from flowing directly into waters is of great significance to improving the ecological environment, enhancing urban taste and promoting economic development. Before sewage is deeply treated, sewage treatment plants usually need to pre-treat it to intercept the garbage floating on the surface of sewage to improve the efficiency of subsequent sewage treatment.

[0003] With regard to the existing related technologies, the inventors believe that the following defects often exist: when the existing technologies need to intercept floating garbage in sewage, a filter is usually placed horizontally in the flow channel to filter the sewage and intercept the floating garbage on the surface of the filter. However, the filter is usually fixed, and it is difficult to clean the garbage on its surface. Over time, excessive accumulation of garbage will clog the holes of the filter, increase the resistance to the water flow, and easily cause the filter to break. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a kind of urban sewage deep treatment equipment described in the present invention comprises:

[0006] A conveying column, wherein a pair of conveying columns are provided, and one of the conveying columns is driven by a motor 1;

[0007] A filter screen, which is sleeved on the surface of a pair of conveying columns; the filter screen is made of elastic material;

[0008] A collection box, the collection box is located on the side of the filter screen; a collection port is provided on the top surface of the collection box;

[0009] An inclined plate mechanism, wherein the inclined plate mechanism is located on the side of the filter screen, and the top of the inclined plate mechanism extends to the inside of the collection port; the side of the inclined plate mechanism is in contact with the filter screen;

[0010] When the prior art needs to intercept the garbage floating in the sewage, the filter is usually placed horizontally in the flow channel to filter the sewage and intercept the floating garbage on the surface of the filter. However, the filter is usually fixed, and it is difficult to clean the garbage on its surface. Over time, too much garbage accumulates and the holes of the filter are blocked, increasing the resistance to the water flow and easily causing the filter to break. At this time, the present invention can set the filter on the water surface, and the collection port is located above the water surface. The flowing sewage is filtered through the filter to intercept the garbage in the water on the surface of the filter. The conveying column is driven to rotate by a motor to drive the filter to move toward the collection box. Since the side of the inclined plate assembly is in contact with the filter, the filter can deliver the garbage on its surface to the surface of the inclined plate, which is convenient for pushing the garbage through the collection port to the inside of the collection box, thereby realizing automatic cleaning of the garbage and avoiding the problem of the filter breaking due to excessive garbage accumulation on the surface of the filter.

[0011] Preferably, the inclined plate mechanism includes an inclined frame, and the inclined frame is fixedly connected to the collection box; a pair of conveying rollers are rotatably connected to the surface of the inclined frame, and one of the conveying rollers is driven by motor 2; a conveyor belt is sleeved on the surface of the pair of conveying rollers; the conveyor belt is made of elastic mesh material; the conveyor rollers are driven to rotate by motor 2, driving the conveyor belt to move toward the collection port, thereby sending the garbage on the surface of the conveyor belt into the collection box, realizing automatic storage of the garbage, and by setting the conveyor belt as a mesh material, the moisture on the surface of the garbage can drip through the holes of the conveyor belt during the transportation process, preventing the problem of reduced storage space after a large amount of water enters the collection box.

[0012] Preferably, a group of convex strips are evenly distributed on the circumference of the conveyor roller surface, and the convex strips are embedded in the holes of the conveyor belt; by providing a plurality of convex strips, the convex strips can be embedded in the holes of the conveyor belt during the rotation of the conveyor roller, which is similar to the meshing effect, thereby improving the traction of the conveyor roller on the conveyor belt, avoiding slipping, and ensuring the smooth transportation of garbage.

[0013] Preferably, the surface of the inclined frame is fixedly connected with a mounting plate; the mounting plate is close to a conveying roller at the top, and the mounting plate is located between the conveyor belts; a group of movable plates are evenly distributed above the mounting plate; a spring is fixedly connected between the movable plate and the mounting plate; a guide rod is fixedly connected to the lower side of the movable plate, and the guide rod passes through the mounting plate and is slidably connected thereto; and a group of elastic sheets are evenly distributed on one end of the guide rod extending below the conveyor belt; in the process of the conveying roller driving the convex bar to rotate, when the convex bar moves to the movable plate, the movable plate will be pushed upward, and then the movable plate will stretch the spring one and drive the guide rod to move upward. Because the elastic sheet is stuck at the edge of the hole of the conveyor belt, the conveyor belt can be driven to deform upward through the elastic sheet. When the conveyor belt reaches the elastic limit, the elastic sheet is squeezed and deformed and then passes over the conveyor belt. At this time, the conveyor belt quickly rebounds downward, and the garbage adhered to its surface is bounced downward and falls into the collection box, thereby improving the garbage collection efficiency and reducing the garbage residue on the surface of the conveyor belt.

[0014] Preferably, a telescopic tube is fixedly connected between the movable plate and the mounting plate, and the telescopic tube is arranged as an elastic corrugated structure; a group of air holes are opened at a position close to the telescopic tube on the lower side of the mounting plate, and the air holes are connected with the inside of the telescopic tube; when the convex strip pushes the movable plate upward, the movable plate will synchronously stretch the telescopic tube, and then the air will be sucked into the telescopic tube through the air holes; when the convex strip is disengaged from the movable plate, the spring will pull the movable plate downward to reset, and compress the telescopic tube, and the air inside the telescopic tube will be ejected downward through the air holes to blow on the surface of the conveyor belt, thereby further blowing away the remaining small garbage and improving the self-cleaning efficiency of the conveyor belt.

[0015] Preferably, pillars are arranged between the filters; a controller and a detection tube are fixedly connected to the surface of the pillars; the controller is used to control the start and stop of motor one and motor two; a slider is slidably connected inside the detection tube; a spring two is fixedly connected between the slider and the end of the detection tube; a contact piece one is fixedly connected inside the detection tube; a contact piece two is fixedly connected to the end of the slider close to the contact piece one, and both the contact piece one and the contact piece two are connected to the controller; under normal circumstances, motor one and motor two are in a stopped state. When a lot of garbage is retained on the surface of the filter, its resistance to the water flow increases, and the water flow forces the filter to deform, and then the filter contacts the slider and pushes the slider into the detection tube, so that the contact piece one and the contact piece two contact, and then the controller controls the motor one and motor two to start for a period of time. This structure can automatically detect the amount of garbage on the surface of the filter, and only start motor one and motor two when there is a lot of garbage, so as to clean and store the garbage, save the cost of sewage treatment, and improve the automation and intelligence of the device.

[0016] Preferably, one end of the slider extending outside the detection tube is fixedly connected to a conical block; the tip of the conical block is fixedly connected to a force-bearing cap, and the force-bearing cap is made of a rigid mesh material; by arranging the conical block at the end of the slider, its resistance to the water flow can be reduced, and the slider can be prevented from being pushed into the interior of the detection tube by the water flow when the water flow is turbulent, causing the controller to be falsely triggered, further improving the stability of automatic detection, and by arranging a mesh-shaped force-bearing cap, the efficiency of the filter screen pressing the slider can be improved.

[0017] Preferably, an annular elastic membrane is fixedly connected between the detection tube and the conical block; the elastic membrane is used to seal the gap between the detection tube and the slider to prevent external water from entering the detection tube and causing short circuit or damage to electronic components. The setting of the elastic membrane does not affect the normal sliding of the slider.

[0018] Preferably, a group of protrusions are evenly distributed on the inner side of the conveyor belt near the inclined frame; a group of support rods are evenly distributed on the upper side of the inclined frame; the top of the support rod is rotatably connected to a roller via a rotating shaft, and the roller is in contact with the inner side of the conveyor belt; during the movement of the conveyor belt, the roller can roll on the inner surface of the conveyor belt, and when the roller rolls to the protrusion, the conveyor belt is pressed by the protrusion, so that the conveyor belt bulges upward partially, thereby causing the movement process of the conveyor belt to have a slight shaking effect, which can shake off the moisture on the surface of the garbage, improve the separation efficiency between moisture and garbage, and further reduce the problem of moisture entering the collection box and causing its storage space to decrease.

[0019] Preferably, a flexible block is fixedly connected to the bottom of the protrusion, and the flexible block is made of a water-absorbing material; a connecting hole is opened inside the protrusion; one end of the connecting hole extends to the conveyor belt, and the other end extends to the flexible block; by providing the flexible block and the connecting hole, moisture on the surface of the garbage can enter the connecting hole through the conveyor belt, and then the flexible block absorbs the water after contacting with the water, and subsequently when the roller moves to the protrusion, it will squeeze the flexible block, and the moisture inside the flexible block can be squeezed out, thereby flushing the surface of the roller and the rotating shaft, preventing the problem of impurities adhering to the rotating shaft and affecting the normal rotation of the roller, thereby improving the rotation efficiency of the roller.

[0020] The present invention also provides a process for deep treatment of urban sewage, which uses the above-mentioned equipment for deep treatment of urban sewage and comprises the following steps:

[0021] S1: The filter is set on the water surface, and the collection port is located above the water surface. The flowing sewage is filtered through the filter, and the garbage in the water is intercepted on the surface of the filter;

[0022] S2: The conveying column is driven to rotate by the motor 1, driving the filter to move toward the collection box, and then the filter sends the garbage on its surface to the surface of the inclined plate;

[0023] S3: The conveyor roller is driven to rotate by motor 2, driving the conveyor belt to move toward the collection port, and then the garbage on the surface of the conveyor belt is sent into the collection box. During the transportation process, the moisture on the surface of the garbage can drip through the holes of the conveyor belt.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The urban sewage deep treatment equipment and treatment process described in the present invention filters the flowing sewage through the filter screen, intercepts the garbage in the water on the surface of the filter screen, and drives the conveying column to rotate through a motor to drive the filter screen to move toward the collection box. Since the side of the inclined plate assembly is in contact with the filter screen, the filter screen can deliver the garbage on its surface to the inclined plate surface, which is convenient for pushing the garbage into the collection box through the collection port, realizing automatic cleaning of the garbage and avoiding the problem of the filter screen breaking due to excessive garbage accumulation on the surface of the filter screen.

[0026] 2. The urban sewage deep treatment equipment and treatment process described in the present invention drives the conveyor roller to rotate through motor 2, driving the conveyor belt to move toward the collection port, and then sends the garbage on the surface of the conveyor belt into the collection box, thereby realizing automatic storage of the garbage. In addition, by setting the conveyor belt as a grid material, the moisture on the surface of the garbage can drip through the holes of the conveyor belt during transportation, thereby preventing the problem of reduced storage space after a large amount of water enters the collection box.

[0038] A conveying column 1, wherein a pair of conveying columns 1 is provided, and one of the conveying columns 1 is driven by a motor 1;

[0039] A filter screen 2, the filter screen 2 is sleeved on the surface of a pair of conveying columns 1; the filter screen 2 is made of elastic material;

[0040] A collecting box 3, the collecting box 3 is located on the side of the filter screen 2; a collecting port 4 is provided on the top surface of the collecting box 3;

[0041] The inclined plate mechanism is located on the side of the filter screen 2, and the top of the inclined plate mechanism extends to the inside of the collecting port 4; the side of the inclined plate mechanism is in contact with the filter screen 2.

[0042] When the prior art needs to intercept the garbage floating in the sewage, the filter 2 is usually placed horizontally in the flow channel to filter the sewage and intercept the floating garbage on the surface of the filter 2. However, the filter 2 is usually fixed, and it is difficult to clean the garbage on its surface. Over time, too much garbage accumulates, which will clog the holes of the filter 2, increase the resistance to the water flow, and easily cause the filter 2 to break. At this time, the present invention can set the filter 2 at the water surface, and the collection port 4 is located above the water surface. The flowing sewage is filtered by the filter 2 to intercept the garbage in the water on the surface of the filter 2, and the conveying column 1 is driven to rotate by the motor to drive the filter 2 to move toward the collection box 3. Since the side of the inclined plate assembly is in contact with the filter 2, the filter 2 can deliver the garbage on its surface to the surface of the inclined plate, which is convenient for pushing the garbage through the collection port 4 to the inside of the collection box 3, thereby realizing automatic cleaning of the garbage and avoiding the problem of the filter 2 breaking due to excessive garbage accumulation on the surface of the filter 2.

[0043] The inclined plate mechanism includes an inclined frame 5, and the inclined frame 5 is fixedly connected to the collection box 3; a pair of conveying rollers 6 are rotatably connected to the surface of the inclined frame 5, and one of the conveying rollers 6 is driven by a second motor; a conveyor belt 7 is sleeved on the surface of the pair of conveying rollers 6; the conveyor belt 7 is made of an elastic mesh material; the conveyor rollers 6 are driven to rotate by the second motor, so as to drive the conveyor belt 7 to move toward the collection port 4, and then the garbage on the surface of the conveyor belt 7 is sent into the collection box 3, so as to realize automatic storage of the garbage, and by setting the conveyor belt 7 as a mesh material, the moisture on the surface of the garbage can drip through the holes of the conveyor belt 7 during the transportation process, so as to prevent the problem of reduced storage space after a large amount of water enters the collection box 3.

[0044] A group of convex strips 8 are evenly distributed on the circumference of the surface of the conveying roller 6, and the convex strips 8 are embedded in the holes of the conveying belt 7; by providing a plurality of convex strips 8, the convex strips 8 can be embedded in the holes of the conveying belt 7 during the rotation of the conveying roller 6, which is similar to the meshing effect, thereby improving the traction of the conveying roller 6 on the conveying belt 7, avoiding slipping, and ensuring the smooth transportation of garbage.

[0045] The surface of the tilting frame 5 is fixedly connected with a mounting plate 9; the mounting plate 9 is close to a conveying roller 6 at the top, and the mounting plate 9 is located between the conveyor belts 7; a group of movable plates 10 are evenly distributed above the mounting plate 9; a spring 11 is fixedly connected between the movable plate 10 and the mounting plate 9; a guide rod 12 is fixedly connected to the lower side of the movable plate 10, and the guide rod 12 passes through the mounting plate 9 and is slidably connected thereto; a group of elastic sheets 13 are evenly distributed on one end of the guide rod 12 extending below the conveyor belt 7; during the process of the conveyor roller 6 driving the convex strip 8 to rotate, when the convex strip 8 moves When it reaches the movable plate 10, the movable plate 10 will be pushed upward, and then the movable plate 10 will stretch the spring 11 and drive the guide rod 12 to move upward. Since the elastic sheet 13 is stuck on the edge of the hole of the conveyor belt 7, the conveyor belt 7 can be driven by the elastic sheet 13 to deform upward. When the conveyor belt 7 reaches its elastic limit, the elastic sheet 13 is squeezed and deformed and passes over the conveyor belt 7. At this time, the conveyor belt 7 quickly rebounds downward, and the garbage adhered to its surface is bounced downward and falls into the collection box 3, thereby improving the garbage collection efficiency and reducing the residual garbage on the surface of the conveyor belt 7.

[0046] A telescopic tube 14 is fixedly connected between the movable plate 10 and the mounting plate 9, and the telescopic tube 14 is arranged as an elastic corrugated structure; a group of air holes 15 are provided at a position near the telescopic tube 14 on the lower side of the mounting plate 9, and the air holes 15 are connected to the inside of the telescopic tube 14; when the convex strip 8 pushes the movable plate 10 upward, the movable plate 10 simultaneously stretches the telescopic tube 14, and then air is sucked into the telescopic tube 14 through the air holes 15; when the convex strip 8 is disengaged from the movable plate 10, the spring 11 pulls the movable plate 10 downward to reset, and compresses the telescopic tube 14, and the air inside the telescopic tube 14 is ejected downward through the air holes 15 to blow on the surface of the conveyor belt 7, thereby further blowing away the remaining small pieces of garbage and improving the self-cleaning efficiency of the conveyor belt 7.

[0047] A support 16 is provided between the filter screens 2; a controller 17 and a detection tube 18 are fixedly connected to the surface of the support 16; the controller 17 is used to control the start and stop of motor 1 and motor 2; a slider 19 is slidably connected inside the detection tube 18; a spring 20 is fixedly connected between the slider 19 and the end of the detection tube 18; a contact piece 1 21 is fixedly connected inside the detection tube 18; a contact piece 22 is fixedly connected to the end of the slider 19 close to the contact piece 1 21, and the contact piece 1 21 and the contact piece 22 are both connected to the controller 17; under normal circumstances, motor 1 and motor 2 In the stopped state, when more garbage is retained on the surface of the filter 2, its resistance to the water flow increases, and the water flow forces the filter 2 to deform, and then the filter 2 contacts the slider 19 and pushes the slider 19 into the detection tube 18, so that the contact piece 1 21 contacts the contact piece 2 22, and then the controller 17 controls the motor 1 and the motor 2 to start for a period of time. This structure can automatically detect the amount of garbage on the surface of the filter 2, and only start the motor 1 and the motor 2 when there is a lot of garbage, so as to clean and store the garbage, save the cost of sewage treatment, and improve the automation and intelligence of the device.

[0048] The end of the slider 19 extending outside the detection tube 18 is fixedly connected to a conical block 23; the tip of the conical block 23 is fixedly connected to a force cap 24, and the force cap 24 is made of a rigid grid material; by arranging the conical block 23 at the end of the slider 19, its resistance to the water flow can be reduced, and the slider 19 can be prevented from being pushed into the detection tube 18 by the water flow when the water flow is turbulent, causing the controller 17 to be triggered incorrectly, further improving the stability of automatic detection, and by arranging the grid-shaped force cap 24, the compression efficiency of the filter 2 on the slider 19 can be improved.

[0049] An annular elastic membrane 25 is fixedly connected between the detection tube 18 and the conical block 23; the elastic membrane 25 is used to seal the gap between the detection tube 18 and the slider 19 to prevent external water from entering the detection tube 18 and causing short circuit or damage to electronic components. The setting of the elastic membrane 25 does not affect the normal sliding of the slider 19.

[0050] Embodiment 2: Figure 6 As shown, compared with Example 1, another implementation of the present invention is: a group of protrusions 26 are evenly distributed on the inner side of the conveyor belt 7 near the inclined frame 5; a group of support rods 27 are evenly distributed on the upper side of the inclined frame 5; the top of the support rod 27 is rotatably connected to a roller 29 through a rotating shaft 28, and the roller 29 is in contact with the inner side of the conveyor belt 7; during the movement of the conveyor belt 7, the roller 29 can roll on the inner surface of the conveyor belt 7. When the roller 29 rolls to the protrusion 26, the conveyor belt 7 is pressed by the protrusion 26, so that the conveyor belt 7 partially bulges upward, thereby causing the movement process of the conveyor belt 7 to have a slight shaking effect, which can shake off the moisture on the surface of the garbage, improve the separation efficiency between moisture and garbage, and further reduce the problem of moisture entering the collection box 3 and causing its storage space to decrease.

[0051] A flexible block 30 is fixedly connected to the bottom of the protrusion 26, and the flexible block 30 is made of a water-absorbing material; a connecting hole 31 is opened inside the protrusion 26; one end of the connecting hole 31 extends to the conveyor belt 7, and the other end extends to the flexible block 30; by setting the flexible block 30 and the connecting hole 31, the moisture on the surface of the garbage can enter the inside of the connecting hole 31 through the conveyor belt 7, and then the flexible block 30 absorbs the water after contacting with the water, and then when the roller 29 moves to the protrusion 26, it will squeeze the flexible block 30, and the moisture inside the flexible block 30 can be squeezed out, thereby washing the surface of the roller 29 and the rotating shaft 28, preventing the problem of a large amount of impurities adhering to the rotating shaft 28 and affecting the normal rotation of the roller 29, thereby improving the rotation efficiency of the roller 29.

[0052] like Figure 7 As shown, a process for deep treatment of urban sewage, which uses the above-mentioned equipment for deep treatment of urban sewage, comprises the following steps:

[0053] S1: The filter 2 is set at the water surface, and the collection port 4 is located above the water surface, and the flowing sewage is filtered through the filter 2 to intercept the garbage in the water on the surface of the filter 2;

[0054] S2: The conveying column 1 is driven to rotate by the motor 1, driving the filter screen 2 to move toward the collecting box 3, and then the filter screen 2 sends the garbage on its surface to the surface of the inclined plate;

[0055] S3: The conveyor roller 6 is driven to rotate by the second motor, driving the conveyor belt 7 to move toward the collecting port 4, and then the garbage on the surface of the conveyor belt 7 is sent into the collecting box 3. During the transportation process, the moisture on the surface of the garbage can drip through the holes of the conveyor belt 7.

[0056] Working principle: The filter screen 2 is set at the water surface, and the collection port 4 is located above the water surface. The flowing sewage is filtered through the filter screen 2, and the garbage in the water is intercepted on the surface of the filter screen 2. The conveying column 1 is driven to rotate by the motor 1 to drive the filter screen 2 to move toward the collection box 3. Since the side of the inclined plate assembly is in contact with the filter screen 2, the filter screen 2 can send the garbage on its surface to the inclined plate surface, which is convenient for pushing the garbage through the collection port 4 to the inside of the collection box 3, realizing automatic cleaning of the garbage and avoiding the problem of the filter screen 2 breaking due to excessive garbage accumulation on the surface of the filter screen 2; the conveying roller 6 is driven to rotate by the motor 2 to drive the conveyor belt 7 to move in the direction of the collection port 4, and then the garbage on the surface of the conveyor belt 7 is sent into the inside of the collection box 3, realizing the garbage collection. The automatic storage of garbage is realized, and by setting the conveyor belt 7 as a grid material, the moisture on the surface of the garbage can drip through the holes of the conveyor belt 7 during the transportation process, thereby preventing a large amount of water from entering the collection box 3 and causing the storage space to be reduced; by setting a plurality of convex strips 8, the convex strips 8 can be embedded in the holes of the conveyor belt 7 during the rotation of the conveyor roller 6, similar to the meshing effect, thereby improving the traction of the conveyor roller 6 on the conveyor belt 7, avoiding slipping, and ensuring the smooth transportation of the garbage; in the process of the conveyor roller 6 driving the convex strips 8 to rotate, when the convex strips 8 move to the movable plate 10, the movable plate 10 will be pushed upward, and then the movable plate 10 will stretch the spring 11 and drive the guide rod 12 to move upward, because the elastic sheet 13 is stuck At the edge of the hole in the conveyor belt 7, the elastic sheet 13 can drive the conveyor belt 7 to deform upward. When the conveyor belt 7 reaches its elastic limit, the elastic sheet 13 is squeezed and deformed and passes over the conveyor belt 7. At this time, the conveyor belt 7 quickly rebounds downward, and the garbage adhered to its surface is bounced downward and falls into the collection box 3, thereby improving the garbage collection efficiency and reducing the garbage residue on the surface of the conveyor belt 7. When the convex strip 8 pushes the movable plate 10 upward, the movable plate 10 will synchronously stretch the telescopic tube 14, and then the air will be sucked into the telescopic tube 14 through the air hole 15. When the convex strip 8 is separated from the movable plate 10, the spring 11 pulls the movable plate 10 to reset downward and compresses the telescopic tube 14. The air inside the telescopic tube 14 is ejected downward through the air hole 15, The surface of the conveyor belt 7 is blown, thereby further blowing away the remaining small garbage, improving the self-cleaning efficiency of the conveyor belt 7; under normal circumstances, the motor 1 and the motor 2 are in a stopped state. When a lot of garbage is trapped on the surface of the filter screen 2, its resistance to the water flow increases, and the water flow forces the filter screen 2 to deform, and then the filter screen 2 contacts the slider 19 and pushes the slider 19 into the detection tube 18, so that the contact piece 1 21 and the contact piece 2 22 contact, and then the controller 17 controls the motor 1 and the motor 2 to start for a period of time. This structure can automatically detect the amount of garbage on the surface of the filter screen 2, and only start the motor 1 and the motor 2 when there is a lot of garbage, so as to clean and store the garbage, save the cost of sewage treatment, and improve the automation and intelligence of the device;By setting a conical block 23 at the end of the slider 19, its resistance to water flow can be reduced, and when the water flow is turbulent, the slider 19 is prevented from being pushed into the detection tube 18 by the water flow, causing the controller 17 to be triggered by mistake, and the stability of automatic detection is further improved. By setting a grid-shaped force cap 24, the compression efficiency of the filter 2 on the slider 19 can be improved; the gap between the detection tube 18 and the slider 19 is blocked by the elastic membrane 25 to prevent external water from entering the detection tube 18 and causing the electronic components to short-circuit or be damaged. The setting of the elastic membrane 25 does not affect the normal sliding of the slider 19; during the movement of the conveyor belt 7, the roller 29 can roll on the inner surface of the conveyor belt 7. When the roller 29 rolls to the convex block 26, the conveyor belt is pressed by the convex block 26. 7, so that the conveyor belt 7 partially bulges upward, so that the movement process of the conveyor belt 7 has a slight shaking effect, which can shake off the moisture on the surface of the garbage, improve the separation efficiency between moisture and garbage, and further reduce the problem of moisture entering the collection box 3 and causing its storage space to decrease; by setting the flexible block 30 and the connecting hole 31, the moisture on the surface of the garbage can enter the inside of the connecting hole 31 through the conveyor belt 7, and then the flexible block 30 absorbs the water after contacting with the water. Later, when the roller 29 moves to the convex block 26, it will squeeze the flexible block 30, which can squeeze out the moisture inside the flexible block 30, thereby washing the surface of the roller 29 and the rotating shaft 28, preventing the problem of a lot of impurities adhering to the rotating shaft 28 and affecting the normal rotation of the roller 29, and improving the rotation efficiency of the roller 29. ;
