[0019] The following combines the embodiments and the attached Figures 1 to 3 , and further elaborates on the technical solutions of the present utility model.

[0020] Embodiment 1

[0021] A crusher includes: a crushing main body 1, the crushing main body 1 includes a fixed table 11, a crushing chamber 12 arranged on the fixed table 11, and an auger feeding mechanism 13 arranged on the side wall of the crushing chamber 12. The upper end of the crushing chamber 12 is connected to a cyclone separator 2 through a pipeline. A collection bin 21 is arranged at the lower end of the cyclone separator 2, and a dust removal device 3 is connected to the upper end through a pipeline. An induced draft fan 4 is arranged at the upper end of the dust removal device 3.

[0022] As Figures 1 to 3 shown, in the present utility model, the crushing main body 1 is supported by the fixed table 11, with the crushing chamber 12 installed on it, and the auger feeding mechanism 13 is arranged on the side wall of the crushing chamber 12. This auger feeding method has significant advantages: it can evenly and continuously feed materials into the crushing chamber, avoiding the blockage and uneven distribution problems that may occur in traditional feeding methods, thereby improving the crushing efficiency and output.

[0023] During the crushing process, the materials are stably fed into the crushing chamber 12 through the auger feeding mechanism 13 for crushing. The crushed materials are sent into the cyclone separator 2 through the upper pipeline for preliminary separation. This step effectively separates the materials from the dust, laying a foundation for subsequent collection and dust removal. The separated materials enter the collection bin 21, while the lighter dust is sent into the dust removal device 3 and further removed through the negative pressure generated by the induced draft fan 4.

[0024] The configuration of the dust removal device 3 not only optimizes the working environment, but also ensures the purity of the materials, meeting the requirements for the handling of high-purity materials. The design of the entire crusher takes into account the convenience of maintenance and cleaning. By regularly cleaning and maintaining the cyclone separator 2, the collection bin 21, and the dust removal device 3, the stable operation of the equipment and the efficient dust removal effect are ensured.

[0025] As a further preferred embodiment, the auger feeding mechanism 13 includes a housing 131 and blades 132 rotatably disposed within the housing 131. One end of the blades 132 penetrates through the lower end of the housing 131 and is in transmission connection with the driving mechanism. A feeding port 1311 is provided at the upper end of the housing 131, and a feeding opening 1312 is provided at the lower end of the housing 131. The feeding opening 1312 is in through communication with the crushing chamber 12.

[0026] Specifically, the auger feeding mechanism 13 is composed of a housing 131 containing rotating blades 132. One end of these blades is connected to the driving mechanism, ensuring its stable rotation ability. A feeding port 1311 is provided at the upper end of the housing 131 for facilitating the addition of materials; while the feeding opening 1312 at the lower end is in through communication with the crushing chamber 12, forming a passage for materials to enter the crushing chamber. When the blades 132 rotate, the materials are effectively pushed from the feeding port 1311 to the feeding opening 1312 and evenly enter the crushing chamber 12, ensuring the continuity of the crushing process and the uniform distribution of materials. This not only improves production efficiency but also reduces the wear inside the crushing chamber 12 caused by uneven material feeding, extending the service life of the equipment. At the same time, the compact structural design of the auger feeding mechanism 13 reduces space occupation, facilitating integration and maintenance, and its easy-to-operate feature reduces the operation difficulty and improves the operation safety.

[0027] As a further preferred embodiment, a discharge ring groove 1313 is provided at the lower end of the housing 131. The discharge ring groove 1313 inclines towards the feeding opening 1312 and its lowest end is at the same level as the lower end of the feeding opening 1312, facilitating the entry of materials from the feeding opening 1312 into the crushing chamber 12.

[0028] As a further preferred embodiment, the dust removal device 3 includes an upper pulse precipitation chamber 31 and a collection cloth bag 32 located below the pulse precipitation chamber 31. An isolation plate 311 is provided at the upper end of the pulse precipitation chamber 31. The pipeline connected to the cyclone separator 2 is located below the isolation plate 311, and the pipeline connected to the induced draft fan 4 is located above the isolation plate 311.

[0029] Specifically, the dust removal device 3 includes two parts: a pulse sedimentation chamber 31 and a collection cloth bag 32. The pulse sedimentation chamber 31 is located at the upper part of the dust removal device and is responsible for sedimenting and purifying the dust-containing gas. An isolation plate 311 is installed at the upper end of its interior to separate the chamber space, such that the pipeline connected to the cyclone separator 2 is located below the isolation plate 311, while the pipeline connected to the induced draft fan 4 is located above the isolation plate 311. This layout optimizes the gas flow and dust sedimentation process.

[0030] The collection cloth bag 32 is arranged below the pulse sedimentation chamber 31 and is used to capture the fine dust after being treated by the sedimentation chamber. This design not only improves the dust removal efficiency but also facilitates the replacement and cleaning of the collection cloth bag, reducing the maintenance cost and labor intensity. In addition, the pulse sedimentation chamber 31 may be equipped with a pulse jet device (to periodically clean the collection cloth bag 32 to prevent blockage and maintain the dust removal efficiency.

[0031] Generally speaking, through the cooperation of the pulse sedimentation chamber 31 and the collection cloth bag 32, the dust removal device 3 achieves high-efficient dust removal performance and optimized gas flow, while simplifying the maintenance process and reducing the operation cost.

[0032] As a further preferred embodiment, a silencer 5 is provided at the end of the pipeline connecting the dust removal device 3 and the induced draft fan 4. The silencer 5 is installed at the end of the pipeline connecting the dust removal device 3 and the induced draft fan 4, and is designed to reduce the noise generated by gas flow.
