[0002] During the incineration process of hazardous waste, materials need to be continuously transported into the rotary kiln. Due to the different properties of the materials, in order to smoothly transport the materials to the rotary kiln, it is often necessary to use a pushing device to push the materials into the rotary kiln.

[0003] However, when the existing pusher device pushes the material, part of the material is easily adhered to the upper pusher head, so when the pusher head withdraws, a lot of material will be taken out, which will not only affect the feeding effect, but also the material will become thicker and thicker on the pusher head in the long-term operation, which will affect the operation of the pusher device. Therefore, it is necessary to provide an automatic cleaning device to prevent material backflow to solve the above problems. Utility Model Content

A cavity is provided in the pushing block, and two through holes are opened on the inner wall of the cavity away from the fixed block; two winding rollers rotatably installed on the inner wall of the cavity, the two winding rollers are wrapped with the same pushing belt, and the pushing belt is slidably connected to the two through holes; two scrapers fixedly installed on one side of the pushing block away from the fixed block and located at both ends of the pushing belt for cleaning materials; a rotating mechanism assembled on the pushing block for rotating the two winding rollers; a disassembly mechanism mounted on the mounting shell for cooperating with the two slots to clamp the fixed block.

[0006] Preferably, the rotating mechanism comprises: a servo motor fixedly mounted on the inner wall of the cavity, a gear fixedly sleeved on the output shaft of the servo motor; and two gear rings fixedly sleeved on the two winding rollers respectively, both of which are meshed with the gear.

[0007] Preferably, the disassembly mechanism includes: a bidirectional screw rotatably mounted on the mounting shell and perpendicular to the axial direction of the pushing cylinder, two connecting plates being threadedly mounted on the two threaded sections of the bidirectional screw; and two plug blocks respectively fixedly mounted on the two connecting plates, the two plug blocks respectively matching the two slots.

[0008] Preferably, two positioning plates are fixedly installed on both sides of the push cylinder, and limiting rods parallel to the axis of the push cylinder are slidably installed on the two positioning plates, and one end of the two limiting rods is fixedly connected to one side of the push block close to the mounting shell.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides an automatic cleaning device to prevent material backflow, such as Figure 1-4As shown, the automatic cleaning device for preventing material backflow comprises: a pushing cylinder 1, a mounting shell 2 is fixedly mounted on the output rod of the pushing cylinder 1, and an opening is provided at the end of the mounting shell away from the material return cylinder; a fixed block 3 slidably mounted in the opening, two slots are provided on both sides of the fixed block 3, a pushing block 4 is fixedly connected to the end of the fixed block 3 away from the material return cylinder, a cavity is provided in the pushing block 4, and two through holes are provided on the inner wall of the cavity away from the fixed block; two winding rollers 5 rotatably mounted on the inner wall of the cavity, the two winding rollers 5 are wound with the same pushing belt 6, and the pushing belt 6 is slidably connected to the two through holes; two scrapers 7 fixedly mounted on the side of the pushing block 4 away from the fixed block and located at both ends of the pushing belt for cleaning materials; a rotating mechanism mounted on the pushing block 4 for rotating the two winding rollers 5; a disassembly mechanism mounted on the mounting shell 2 for cooperating with the two slots to clamp the fixed block 3.

[0022] In this embodiment, when it is necessary to use the device to push materials into the rotary kiln, the device needs to be installed in a suitable use position. When pushing materials, the pushing cylinder 1 is started to extend the output rod of the pushing cylinder 1. When the output rod is extended, the pushing block 4 can be driven to move, so that the pushing belt 6 on the pushing block 4 pushes the materials into the rotary kiln. When the output rod of the pushing cylinder 1 is contracted, the pushing belt 6 on the pushing block 4 will slowly move to the original position. In order to prevent the materials from being brought out, a rotating mechanism is used to drive the two winding rollers 5 to rotate during the process of the pushing belt 6 returning to the original position. The two winding rollers 5 will rotate in the same reverse direction. One winding roller 5 will rewind the pushing belt 6, and the other winding roller will rewind the pushing belt 6. 5 will release the pushing belt 6, so that the material adhered to the pushing belt 6 will be scraped off by the two scraper plates 7, and the cleaning effect is better. In this way, when the pushing belt 6 returns to its original position, the material will not be brought out, and the use effect is better. Each time the two winding rollers 5 rotate, their rotation direction must be opposite to the previous time. When it is necessary to dismantle and maintain the pushing block 4, it is only necessary to operate the disassembly mechanism to disengage the plug block 13 on the disassembly mechanism from the slot on the fixed block 3. After disengagement, the fixed block 3 can be taken out from the mounting shell 2, and then the pushing block 4 is pulled to one side so that the limit rod 16 and the positioning plate 15 can be separated. After separation, the removal of the pushing block 4 is completed, and the operation is relatively simple.

[0023] In a further preferred embodiment of the utility model, the rotating mechanism includes: a servo motor 8 fixedly mounted on the inner wall of the cavity, a gear 9 fixedly sleeved on the output shaft of the servo motor 8; two gear rings 10 respectively fixedly sleeved on the two winding rollers 5, and both of the two gear rings 10 are meshed with the gear 9.

[0024] In this embodiment, the rotating mechanism is used to rotate the two winding rollers 5. When in use, the servo motor 8 is started. The servo motor 8 can drive the gear 9 to rotate clockwise or counterclockwise. The rotation of the gear 9 will drive the two gear rings 10 to rotate, and the two gear rings 10 will drive the two winding rollers 5 to rotate. The two winding rollers 5 have the same rotation direction, which can move the push belt 6. The material adhered to the push belt 6 will be scraped off by the two scraper plates 7, and the cleaning effect is better.

[0025] In a further preferred embodiment of the utility model, the disassembly mechanism includes: a bidirectional screw 11 rotatably mounted on the mounting shell 2 and perpendicular to the axial direction of the pushing cylinder, two connecting plates 12 being threadedly mounted on the two threaded sections of the bidirectional screw 11; two plug blocks 13 respectively fixedly mounted on the two connecting plates 12, and the two plug blocks 13 are respectively adapted to the two card slots.

[0026] In this embodiment, the disassembly mechanism is used to clamp the fixed block 3. When the clamping work needs to be released, the bidirectional screw 11 is rotated, and the bidirectional screw 11 will drive the two connecting plates 12 to move away from or closer to each other. When the two connecting plates 12 move away from each other, the two plug-in blocks 13 will be disengaged from the two slots on the fixed block 3. After disengagement, the fixed block 3 can be removed from the mounting shell 2.

[0027] In a further preferred embodiment of the utility model, two positioning plates 15 are fixedly installed on both sides of the pushing cylinder 1, and limiting rods 16 parallel to the axial direction of the pushing cylinder are slidably installed on the two positioning plates 15, and one end of the two limiting rods 16 is fixedly connected to one side of the pushing block 4 close to the mounting shell.

[0028] In this embodiment, the two positioning plates 15 and the two limiting rods 16 can ensure that the pusher block 4 remains stable during the movement and is not prone to shaking.

[0029] In a further preferred embodiment of the utility model, two rollers 17 are rotatably mounted on the inner wall of the cavity, and both of the two rollers 17 are in contact with the push belt 6 .

[0030] In this embodiment, the two rollers 17 can make the push belt 6 move more smoothly.

[0031] In a further preferred embodiment of the present invention, knobs are fixedly mounted on both ends of the bidirectional screw rod 11, and a plurality of rubber pads are fixedly mounted on the two knobs.

[0032] In this embodiment, by using two knobs and a plurality of rubber pads in coordination, it is convenient for personnel to rotate the bidirectional screw 11 and slipping is not likely to occur.

[0033] In a further preferred embodiment of the present invention, two telescopic rods 14 are fixedly mounted on the inner wall of the mounting shell 2 , and one end of the two telescopic rods 14 is fixedly connected to one side of the two connecting plates 12 , respectively.

[0034] In this embodiment, by using two telescopic rods 14, the two connecting plates 12 and the two inserting blocks 13 can maintain good stability during the movement, so that the two inserting blocks 13 can be accurately inserted into the two card slots.

[0035] To sum up, compared with the relevant technology, the present device can enable the pushing belt 6 on the pushing block 4 to push the material into the rotary kiln through the pushing cylinder 1. After pushing, the pushing cylinder 1 will retract the pushing belt 6. During the retraction process, a rotating mechanism is required to drive the two winding rollers 5 to rotate so that the material adhered to the pushing belt 6 can be scraped off by the two scraper plates 7, and the cleaning effect is better. In this way, when the pushing belt 6 returns to its original position, the material will not be brought out, and the use effect is better. The two positioning plates 15 and the two limit rods 16 can keep the pushing block 4 stable during the movement and are not prone to shaking. The disassembly mechanism can facilitate personnel to dismantle and install the pushing block 4, which can bring convenience to the maintenance work of the device.
