Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, and in particular to a feeding device for a hazardous waste incinerator. Background Technology

[0002] With social and economic development, the quantity and types of hazardous waste are constantly increasing, attracting widespread attention from society and the public. The indiscriminate discharge and improper disposal of hazardous waste can harm human health, and in the long run, will seriously damage the ecological environment upon which humanity depends for survival. The incineration of hazardous waste is receiving increasing attention, leading to the emergence of numerous hazardous waste incinerators on the market, including auxiliary feeding devices for hazardous waste incinerators. The prior art announcement CN207019081U discloses a feeding auxiliary device for a hazardous waste incinerator, including a guide box and a hydraulic cylinder located on the side of the guide box. A feed box with a right-angled trapezoidal main appearance is fixedly connected to a rectangular notch on one side of the top of the guide box. A waste processing platform with a right-angled triangular structure is fixedly connected to the vertical section inside the feed box. One end of the piston rod of the hydraulic cylinder extends into a through hole located inside the guide box and is fixedly connected to a rectangular plate. A waste pushing plate is fixedly connected to one side of the plate by a second bolt. However, during use, the falling hazardous waste is fast and easily blocks the inlet of the guide box. When blockage occurs, the lack of effective isolation between the material and the high-temperature area can easily lead to a (deflagration) safety accident. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a hazardous waste incinerator feeding device that can cut and crush hazardous waste materials, uniformly feed the hazardous waste materials into the incinerator, avoid blockage, and improve the quality and efficiency of incineration.

[0004] This utility model discloses a feeding device for a hazardous waste incinerator, comprising a feeding box, a feeding component, a pushing component, a conveying component, and a connecting component. The feeding component is installed on the top of the feeding box, the pushing component is installed on the left side wall of the feeding box, and the conveying component is installed on the bottom right side of the feeding box via the connecting component. The input end of the conveying component is connected to the inlet of the incinerator. Hazardous waste is added into the feeding box through the feeding component, which can cut and crush the hazardous waste, improving subsequent incineration efficiency. The pushing component pushes the cut hazardous waste into the conveying component, evenly feeding the hazardous waste into the incinerator, avoiding blockages and improving incineration quality.

[0005] Preferably, the feeding component includes a feeding hopper, a feeding pipe, and a chopping assembly. A feeding port is provided on the top left side of the feeding box, and the feeding pipe is installed at the feeding port. The feeding hopper is connected to the top input end of the feeding pipe. Hazardous waste is added into the feeding hopper and fed into the feeding box through the feeding pipe. The feeding hopper increases the area of ​​the feeding port, which facilitates feeding.

[0006] Preferably, the shredding assembly includes a rotating shaft, multiple sets of cutting blades, and a drive motor. The rotating shaft is rotatably installed inside the feed pipe, and the input end of the rotating shaft is connected to the output end of the drive motor. Multiple sets of cutting blades are installed on the outer wall of the rotating shaft. When the drive motor is started, the rotating shaft rotates, and the rotating shaft drives the multiple cutting blades to rotate, cutting the hazardous waste material falling into the feed pipe, reducing its volume, and improving the quality of subsequent incineration.

[0007] Preferably, the feeding component includes an electric telescopic rod, a push plate, and a baffle. The electric telescopic rod is installed on the lower left side wall of the feeding box. Guide blocks are provided at both ends of the lower inner wall of the feeding box. The telescopic end of the electric telescopic rod is equipped with a push plate, which slides on the lower inner wall of the feeding box. A baffle is installed on the top of the push plate and slides on the left side wall of the feeding box. When the shredded hazardous waste falls into the feeding box, the electric telescopic rod is activated to push the push plate to the right, pushing the hazardous waste inside the feeding box. The baffle can receive and block the falling hazardous waste, facilitating continuous feeding.

[0008] Preferably, it also includes two support slide rods and two connecting plates. The support slide rods are symmetrically installed on the front and rear sides of the push plate. The support slide rods are slidably installed on the left side wall of the feed box. The connecting plate is installed on the left end of the support slide rod. The top of the connecting plate is connected to the bottom of the baffle. When the push plate and the baffle move, they drive the support slide rods to slide on the side wall of the feed box, which can support and guide them, increase the structural strength, and ensure stability.

[0009] Preferably, the conveying components include a connecting pipe, a feed cylinder, a rotating shaft, a conveying motor, a spiral conveying blade, and a connecting sleeve. The connecting pipe is connected to the bottom right side of the feed box. The input end of the feed cylinder is connected to the bottom output end of the connecting pipe. A connecting sleeve is installed at the right end of the feed cylinder. The rotating shaft is rotatably installed inside the feed cylinder. A spiral conveying blade is installed on the outer wall of the rotating shaft. The input end of the rotating shaft is connected to the output end of the conveying motor. The feed cylinder is connected to the feed inlet of the incinerator through the connecting sleeve. The push plate pushes the hazardous waste material to the right and it falls into the feed cylinder through the connecting pipe. The conveying motor is started to drive the rotating shaft to rotate. The rotating shaft drives the spiral conveying blade to rotate, conveying the hazardous waste material to the right in the feed cylinder and feeding it evenly into the incinerator, avoiding blockage and improving incineration efficiency.

[0010] Preferably, it also includes two fixing frames and two fixing connecting plates. The fixing frames are mounted on the top of the fixing frames and the fixing connecting plates are bolted to the bottom of the feed box. The bottom of the fixing frames is connected to the outer wall of the feed cylinder. The fixing frames can support and fix the feed cylinder, increase the connection strength between the feed cylinder and the feed box, and ensure the stability during operation.

[0011] Preferably, it also includes a flame retardant hopper and a valve. The flame retardant hopper is installed on the top right side of the feed cylinder, and a valve is installed on the flame retardant hopper. During normal operation, the valve is closed, and the flame retardant hopper is filled with solid flame retardant. When the positive pressure in the furnace exceeds the set pressure, the valve is opened first, and the rotating shaft drives the spiral conveyor blade to rotate, allowing the solid flame retardant to enter the feed cylinder. When the solid flame retardant fills the spiral gap of the feed cylinder, the rotating shaft stops running, thereby enabling the solid flame retardant to quickly and effectively isolate the material from the high-temperature area and prevent backfire.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the input end of the conveying component is connected to the feed port of the incinerator, and the hazardous waste is added into the feed box through the feeding component, which can cut and crush the hazardous waste, improve the subsequent incineration efficiency, and push the cut hazardous waste into the conveying component through the pushing component, so that the hazardous waste is evenly fed into the incinerator, avoiding blockage and improving the incineration quality.
