[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0016] Example 1: Reference Figure 1-3The dust removal device of the elevator hopper includes a dust removal cover 1, a connecting plate 2 is arranged on the top of the dust removal cover 1, a connecting pipe 13 is arranged on one side of the dust removal cover 1, a shell 3 is connected to one side of the connecting pipe 13, the shell 3 is installed on the connecting plate 2, a negative pressure device 4 is arranged in the shell 3, a dust removal pipe 5 is connected to the bottom of the shell 3, a return pipe 6 is arranged on one side of the dust removal pipe 5, an auger feeding assembly is arranged in the return pipe 6, a lifting assembly is arranged on the outside of the return pipe 6, the bottom of one end of the return pipe 6 is connected to the dust removal pipe 5, and the auger The feeding assembly includes a rotating rod 7 rotatably installed in the return pipe 6, a screw 8 is installed on the rotating rod 7, a first motor 9 is provided on one side of the return pipe 6, and the output shaft of the first motor 9 is connected to one end of the rotating rod 7. The lifting assembly includes a fixed block 10 installed on the outside of the return pipe 6, a threaded rod 11 is installed on the fixed block 10 through a bearing, a moving block 12 is threadedly connected to the threaded rod 11, one side of the moving block 12 is squeezed on the outside of the return pipe 6, and one end of the moving block 12 is installed on the connecting plate 2.
[0017] The shell 3 is divided into two layers. A negative pressure device 4 and a separation plate are arranged inside the upper shell 3. A pipe made of deformable soft rubber is connected to the bottom of the shell 3, so that the shell 3 can be deformed while there will be no air leakage at the connection between the bottom of the shell 3 and the dust removal pipe 5.
[0018] A separation plate is arranged at the bottom of the negative pressure device 4, so that the negative pressure device 4 can exhaust air inside the dust hood 1 and the shell 3, so that the dust inside the dust hood 1 and the shell 3 can stay on the separation plate, and then after the negative pressure device 4 stops running, the dust on the separation plate will fall on the return pipe 6, and then return to the hopper that needs dust removal again through the auger 8.
[0019] During the use of this device, one end of the return pipe 6 needs to be connected to the pipeline, and then the pipeline is connected to the top side of the hopper. During use, the dust cover 1 is used to cover the top of the elevator hopper, and then the output shaft of the second motor 14 drives the threaded rod 11 to rotate. The threaded rod 11 allows the moving block 12 to move on the threaded rod 11, so that the height of the connecting plate 2 can be adjusted, so that the gap between the dust cover 1 and the elevator hopper is smaller, so that the device can absorb the dust above the elevator hopper more effectively; the dust above the elevator hopper will enter the dust cover 1, and then reach the separation plate through the connecting pipe 13, and then fall to the return pipe 6, the output shaft of the first motor 9 will drive the rotating rod 7 to rotate, and the rotating rod 7 drives the auger 8 to rotate, and the auger 8 will allow the dust accumulated in the return pipe 6 to reach the pipeline and return to the elevator hopper again, and send the recovered powder to the hopper, reducing workshop dust, saving materials, and simplifying the recycling process.
[0020] Embodiment 2: Based on embodiment 1, the optimization is carried out. Figure 1-3The outer side of the moving block 12 is provided with a wear-resistant coating, and the bottom of one side of the return pipe 6 is arranged to be inclined.
[0021] The wear-resistant coating on the outer side of the moving block 12 is formed by arc spraying ceramic particles, so that the mechanical properties of the moving block 12 are improved.
[0022] Combined with Figure 1-3 It can be seen that the bottom of the dust removal pipe 5 is vertical on the return pipe 6, so that the bottom of one side of the return pipe 6 is inclined, so that the dust inside the dust removal pipe 5 falls into the return pipe 6, and after the dust accumulates, the dust can quickly reach the auger 8.
[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
