Description

Technical Field

[0001] The utility model relates to the technical field of cement mills, in particular to a feeding device for solid waste disposal. Background Art

[0002] Cement manufacturing often introduces solid waste into the raw meal grinding section to reduce costs. At the same time, materials are transported into the raw meal grinding section through feeding devices. The current feeding devices include conveyor belts, augers, etc.

[0003] The existing Chinese utility model patent with announcement number CN213557376U discloses a feeding device for a roller press in a cement mill system, which is applied to the field of cement mill system technology. The feeding device has an inclined plate on the side of the feeding port, which is inserted into a guide groove. One end of the inclined plate is connected to a telescopic cylinder, and the other end of the telescopic cylinder is connected to a positioning plate, which is connected to the feeding port. This utility model's feeding device for a roller press in a cement mill system has a simple structure, allows for convenient remote control of the inclined plates, ensures that both inclined plates work simultaneously or individually, and allows for timely adjustment of the feeding amount based on production conditions through the control of the inclined plates, thus improving ease of use.

[0004] When disposing of solid wastes of varying moisture content, silos and conveyors are used to transport the materials into the mill. During the unloading and transportation process, due to the large differences in material size and irregular shapes, the flaps on either side of the flap valve can easily get stuck, causing material blockage. Furthermore, the flap valves often remain in a poorly locked airlock state, resulting in severe air leakage in the raw mill system. Utility Model Content

[0010] As a preferred embodiment of this utility model, the crushing motor is rotatably connected to the crushing roller through a gear set, the bottom end of the receiving groove is a cylindrical structure, and the receiving groove is connected to the unloading valve; the receiving groove facilitates material collection.

[0011] As a preferred embodiment of this utility model, the unloading shaft and the unloading valve are rotatably connected, and the unloading shaft is fixedly connected to the rotating shaft of the unloading motor by means of through-installation; the unloading shaft can drive the material to rotate.

[0012] As a preferred embodiment of this utility model, a support column is fixedly installed below the conveying pipe. The conveying pipe has a structure that is thicker at the front and thinner at the back. The support column is symmetrically installed on both the front and back sides below the conveying pipe with the center of the conveying pipe as the reference. The conveying pipe can restrict the position of the material.

[0013] As a preferred embodiment of this utility model, the outer side of the reamer contacts the inner wall of the conveying pipe, the pitch of the reamer decreases from front to back, and the observation window cover is movably connected to the conveying pipe through a threaded structure; the reamer is capable of conveying materials.

[0015] Compared with the prior art, the present invention provides a solid waste disposal device with the following beneficial effects:

[0016] 1. This utility model, through the setting of the crushing roller, allows the crushing motor to drive the crushing roller to rotate via a gear set. After the material passes between the crushing rollers, it is initially crushed by the crushing rollers and falls into the receiving groove. The receiving groove concentrates the material above the discharge valve. The material above the discharge shaft is transferred to the bottom of the discharge shaft by the discharge motor driving the discharge shaft to rotate. The material enters the conveying pipe under the action of gravity. This method can reduce the size difference of the material and avoid the material from clogging the conveying structure.

[0017] 2. This utility model features a conveying pipe with a front-to-back tapering structure, and the reamer's pitch decreases from front to back. When the drive motor starts, the reamer rotates via the drive shaft, causing the material to move backward. Because the conveying pipe's radial diameter decreases backward, the solid waste can be pressurized before entering the mill, making it dense and achieving an airlock effect. This method ensures that the material is compacted at the end of the conveying pipe, thus preventing the raw material mill from connecting with the outside environment at the inlet.

An observation window cover 24 is movably installed above the conveying pipe 2. A connecting pipe 25 is fixedly installed below the conveying pipe 2.

[0032] A support column 26 is fixedly installed below the conveying pipe 2. The conveying pipe 2 has a structure that is thicker at the front and thinner at the back. The support column 26 is symmetrically installed on the front and back sides below the conveying pipe 2 with the center of the conveying pipe 2 as the reference.
