Description

Technical Field

[0001] This utility model relates to the field of hazardous waste incineration technology, specifically a precision feeding device for hazardous waste incineration. Background Technology

[0002] Hazardous waste incineration is a high-temperature thermal treatment technology that refers to the process of incinerating hazardous waste to decompose and render it harmless. It can simultaneously achieve the harmlessness, reduction, and resource recovery of waste.

[0003] Chinese Patent Publication No. CN221975270U discloses a "Feeding Device for Hazardous Waste Incineration," comprising a feeding box with an open feeding hopper at its upper end and a downwardly extending feeding box at its lower end. The feeding box contains a pusher plate, which is a vertically arranged plate whose dimensions match the longitudinal section of the feeding box. The pusher plate reciprocates along the inner wall of the feeding box. This invention solves the problem of hazardous waste accumulation in the feeding box by utilizing a pusher plate, eliminating the need to open the box, thus improving hazardous waste treatment efficiency, reducing personnel contact with hazardous waste, and ensuring personal safety.

[0004] While existing technologies can avoid material accumulation, they require manual handling and lifting for feeding. Hazardous waste may be corrosive, toxic, or radioactive, and manual handling of the feed cylinder can easily lead to skin contact, dust inhalation, or accidental exposure to sources of infection. Furthermore, continuous high-intensity work may cause operators to lose focus, increasing the risk of misoperation such as feed cylinder tipping over or material spillage. In addition, the inability to quantitatively feed materials during use makes it impossible to ensure consistent feeding amounts each time, resulting in drastic fluctuations in temperature and pressure inside the incinerator and affecting combustion efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a precision feeding device for hazardous waste incineration, which solves the problems in the prior art where manual handling and lifting of the feeding cylinder are required during use. Hazardous waste may be corrosive, toxic, or radioactive, and manual handling of the cylinder can easily lead to skin contact, inhalation of dust, or accidental contact with infectious sources. Furthermore, continuous high-intensity operation may cause operators to lose focus, increasing the risk of misoperation such as cylinder tipping or material spillage. At the same time, it is impossible to quantitatively feed the material during use, and it is impossible to ensure that the amount of material fed each time is consistent, resulting in drastic fluctuations in temperature and pressure inside the incinerator, which affects combustion efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A precision feeding device for hazardous waste incineration includes a threaded box and a feeding bin. A feeding component is provided on one side of the threaded box, and a feeding component is provided inside the feeding bin.

[0008] The feeding assembly includes a threaded rod, which is rotatably embedded inside the threaded box. A threaded block is threaded on the outer surface of the threaded rod, and a support rod is rotatably embedded inside the threaded block. A support frame is fixedly connected to the outer surface of the support rod, and support blocks are fixedly connected to both sides of the outer surface of the support frame. A material bucket is fixedly connected to one side of the outer surface of multiple support blocks.

[0009] The feeding assembly includes an output column, which is rotatably embedded inside the feeding bin. A feeding disc is fixedly connected to the outer surface of the output column, a feeding hopper is fixedly connected to the top of the outer surface of the feeding bin, and a feeding pipe is fixedly connected to the bottom of the outer surface of the feeding bin.

[0010] Preferably, a limiting rod is provided inside the thread box, and the threaded block is slidably sleeved on the outer surface of the limiting rod.

[0011] Preferably, a connecting plate is fixedly connected to one side of the outer surface of the thread box, and a flipping block is fixedly connected to one side of the outer surface of the connecting plate.

[0012] Preferably, a support arm is fixedly connected to the outer surface of the support rod, and a connecting column is rotatably embedded inside the support arm. A roller is rotatably sleeved on the outer surface of the connecting column, and the roller is slidably embedded inside the flipping block.

[0013] Preferably, a first motor is fixedly connected to the top of the outer surface of the threaded box, and the output shaft of the first motor is fixedly connected to the threaded rod.

[0014] Preferably, a second motor plate is fixedly connected to one side of the outer surface of the feeding hopper, and a second motor is provided on the top of the outer surface of the second motor plate, with the output shaft of the second motor fixedly connected to the output column.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] 1. By activating the first motor at the top of the threaded box, the first motor drives the threaded rod to rotate. The rotation of the threaded rod causes the threaded block with the threaded sleeve to move. The movement of the threaded block causes the support rod to move. When the support rod moves, the roller slides inside the tilting block. At this time, the threaded block continues to move. Through the limiting of the tilting block, the support frame is tilted around the support rod at the level of the tilting block. The tilting of the support frame adds the material in the material bucket into the feed hopper. Through the above technical solution, the risks of manual handling are avoided. Hazardous waste materials may contain toxic and harmful substances. Manual handling can easily lead to skin contact and inhalation of dust. It also reduces the risk of muscle strain or falls caused by heavy physical labor for operators.

[0017] 2. After the material enters the feeding hopper, the second motor on the top of the second motor plate is turned on. The second motor drives the output column to rotate, which in turn drives the feeding disc to rotate. The rotation of the feeding disc conveys the material from inside the feeding hopper to the feeding pipe. By adjusting the rotation speed of the feeding disc, the total amount of material fed in can be controlled. Through the above technical solution, the sudden changes in temperature and pressure inside the incinerator caused by fluctuations in the amount of material fed in are avoided, ensuring complete combustion of waste, reducing the amount of residue, and avoiding incomplete combustion and the generation of harmful gases due to excessive feeding.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A precision feeding device for hazardous waste incineration includes a threaded box 1 and a feeding bin 2. A feeding component is provided on one side of the threaded box 1, and a feeding component is provided inside the feeding bin 2.

[0025] The feeding assembly includes a threaded rod 3, which is rotatably embedded inside the threaded box 1. A threaded block 301 is threadedly sleeved on the outer surface of the threaded rod 3, and a support rod 402 is rotatably embedded inside the threaded block 301. A support frame 401 is fixedly connected to the outer surface of the support rod 402, and support blocks 403 are fixedly connected to both sides of the outer surface of the support frame 401. A material bucket 4 is fixedly connected to one side of the outer surface of the multiple support blocks 403.

[0026] The feeding assembly includes an output column 601, which is rotatably embedded inside the feeding bin 2. A feeding plate 6 is fixedly connected to the outer surface of the output column 601. A feeding hopper 201 is fixedly connected to the top of the outer surface of the feeding bin 2, and a feeding pipe 202 is fixedly connected to the bottom of the outer surface of the feeding bin 2.

[0027] Through the above technical solution, by activating the first motor 303 at the top of the threaded box 1, the first motor 303 drives the threaded rod 3 to rotate. The rotation of the threaded rod 3 drives the threaded block 301 with threaded sleeve to move. The movement of the threaded block 301 drives the support rod 402 to move. When the support rod 402 moves, the roller 501 slides inside the flipping block 5. At this time, the threaded block 301 continues to move. Through the limiting of the flipping block 5, the support frame 401 flips around the support rod 402 at the level of the flipping block 5. The flipping of the support frame 401 adds the material in the material bucket 4 into the feed hopper 201. Through the above technical solution, the risks of manual handling are avoided. Hazardous waste materials may contain toxic and harmful substances. Manual handling is prone to skin contact and dust inhalation. It also reduces the risk of muscle strain or falls caused by heavy physical labor for operators.

[0028] Through the above technical solution, when the material enters the feed hopper 201, the second motor 7 at the top of the second motor plate 701 is turned on. The second motor 7 drives the output column 601 to rotate, and the rotation of the output column 601 drives the feeding disc 6 to rotate. The rotation of the feeding disc 6 conveys the material from inside the feed hopper 201 to the feeding pipe 202. By adjusting the rotation speed of the feeding disc 6, the total amount of material fed in is controlled. Through the above technical solution, the sudden changes in temperature and pressure in the incinerator caused by fluctuations in the amount of material fed in are avoided, ensuring complete combustion of waste, reducing the amount of residue, and avoiding incomplete combustion and the generation of harmful gases due to excessive feeding.

[0029] Specifically, the threaded box 1 is provided with a limit rod 302 inside, and the threaded block 301 is slidably sleeved on the outer surface of the limit rod 302.

[0030] The above technical solution limits the threaded block 301 by using the limiting rod 302.

[0031] Specifically, a connecting plate 101 is fixedly connected to one side of the outer surface of the thread box 1, and a flipping block 5 is fixedly connected to one side of the outer surface of the connecting plate 101.

[0032] The above technical solution is used to flip the material bucket 4 by flipping block 5.

[0033] Specifically, a support arm 503 is fixedly connected to the outer surface of the support rod 402, and a connecting column 502 is rotatably embedded inside the support arm 503. A roller 501 is rotatably sleeved on the outer surface of the connecting column 502, and the roller 501 is slidably embedded inside the flip block 5.

[0034] Through the above technical solution, by limiting the position of the flipping block 5, the support frame 401 can be flipped around the support rod 402 as the center at the position flush with the flipping block 5.

[0035] Specifically, a first motor 303 is fixedly connected to the top of the outer surface of the thread box 1, and the output shaft of the first motor 303 is fixedly connected to the thread rod 3.

[0036] The above technical solution enables the first motor 303 to drive the threaded rod 3 to rotate.

[0037] Specifically, a second motor plate 701 is fixedly connected to one side of the outer surface of the feeding bin 2, and a second motor 7 is provided on the top of the outer surface of the second motor plate 701. The output shaft of the second motor 7 is fixedly connected to the output column 601.

[0038] Through the above technical solution, the output column 601 is rotated by the second motor 7.

[0039] In use, the first motor 303 at the top of the threaded box 1 is activated, driving the threaded rod 3 to rotate. This rotation moves the threaded block 301, which in turn moves the support rod 402. As the support rod 402 moves, the roller 501 slides inside the tilting block 5. The threaded block 301 continues to move, and the tilting block 5 limits its movement, causing the support frame 401 to tilt around the support rod 402 at a point flush with the tilting block 5. This tilting of the support frame 401 allows material from the material bucket 4 to be added to the feed hopper 201. This technical solution avoids manual risks, as hazardous waste may contain toxic or harmful substances. Manual handling can easily lead to skin contact and dust inhalation. This method reduces the risk of muscle strain or falls caused by heavy physical labor. When material enters the feed hopper 201, the second motor 7 at the top of the second motor plate 701 is activated. The second motor 7 drives the output column 601 to rotate, which in turn drives the feeding disc 6 to rotate. The rotation of the feeding disc 6 transports the material from the feed hopper 201 to the feeding pipe 202. Adjusting the rotation speed of the feeding disc 6 controls the total amount of material fed. This technical solution avoids sudden changes in temperature and pressure inside the incinerator due to fluctuations in the amount of material fed, ensuring complete combustion of waste, reducing residue, and preventing incomplete combustion and the generation of harmful gases due to excessive feeding.
