Leather dust collecting and compressing device

[0018] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0019] Such as figure 1 As shown, a leather dust collection and compression device according to a preferred embodiment of the present invention includes a fan 1, a filter device 2, a dust compressor 3, and a dust pipe 4 for connecting the exhaust port of the leather grinding machine. The dust pipe 4 is connected to the filter device 2, the fan 1 is arranged on the dust pipe 4, the filter device 2 is in communication with the dust compressor 3, and the filter device 2 is provided with an air outlet twenty one.

[0020] The leather dust collection and compression device based on the above technical features connects the dust pipe 4 to the exhaust port of the leather grinding machine, and the dust pipe 4 is connected to the filter device 2. At the same time, a fan 1 is installed on the dust pipe 4, and the leather grinding machine discharges The dust is transported by the fan 1 to the filter device 2 for filtering, and the removed dust enters the dust compressor 3 for compression, and reaches a combustible compression state for use as fuel, realizing waste utilization. At the same time, the filtered air is discharged from the air outlet 21. The invention has simple structure, good use effect, and is easy to popularize and use.

[0021] In this embodiment, the filter device 2 includes a housing 22 and a filter arranged inside the housing 22, the dust pipe 4 is passed through the housing 22, and the output end of the dust pipe 4 is located at Inside the housing 22, and the filter is arranged at the output end of the dust pipe 2. After the dust enters the housing 22, it is filtered by the filter, and the dust falls from the bottom of the housing 22 into the dust compressor 3 for compression, and the filtered air is discharged from the air outlet 21 to ensure The cleanliness of the exhaust gas. At the same time, in order to ensure the filtering effect, the filter includes a first filter screen 23 and a second filter screen 24 arranged in sequence along the dust movement direction. The second filter screen 24 has a smaller pore size than the first filter screen 23. , After the double filtering of the first filter 23 and the second filter 24, the filtering effect is ensured.

[0022] In addition, in order to ensure the installation of the filter and facilitate the filtered dust to fall to the dust compressor 3, a mounting plate 25 is provided inside the housing 22, and the mounting plate 25 divides the housing 22 Is an upper shell 221 and a lower shell 222, the mounting plate 25 is provided with a through hole 251 for dust to pass through, and the filter is arranged in the upper housing 221 and fixed on the mounting plate 25 . At the same time, the lower housing 222 has an inverted cone shape, and a discharge hole 26 is provided in the center of the lower housing 222. The discharge hole 26 is connected to the dust compressor 3 through a pipe. With valve 5. The dust collected by the filter falls from the through hole 251 to the lower housing 222. At the same time, the lower housing 222 is set in an inverted cone shape to facilitate dust falling into the discharge hole 26 to enter the dust compressor 3 for compression. By setting the valve 5, the communication or disconnection between the filter and the dust compressor 3 can be manually controlled according to needs.

[0023] In this embodiment, the dust compressor 3 includes a frame 31, a compression box 32, and a feed pipe 33. The compression box 32 is arranged at the upper end of the frame 31, and the upper end of the compression box 32 is provided with a An oil cylinder 34, a compression plate 35 is provided on the cylinder rod of the first oil cylinder 34, a second oil cylinder 36 and a third oil cylinder 37 are respectively provided on the adjacent two sides of the compression box 32, the second oil cylinder 36 and The cylinder rod of the third cylinder 37 is provided with a first push plate 38 and a second push plate 39 respectively. The compression box 32 is provided with a discharge port 3a on the side opposite to the third cylinder 37. One end of the tube 33 is connected with the compression box 32, and the other end is connected with the filter device 2. By arranging a first oil cylinder 34 at the upper end of the compression box 32 and a second oil cylinder 36 and a third oil cylinder 37 on the adjacent two sides, the first oil cylinder 34 moves from top to bottom after the dust enters the compression box 32 The dust is compressed for the first time, and then the second oil cylinder 36 pushes the dust and compresses it for the second time. Finally, the third oil cylinder 37 compresses the dust for the third time and pushes it to the discharge port 3a. The density of the material is high, and the volume of the material is small, forming a combustible compressed state to be used as fuel, realizing waste utilization.

[0024] In this embodiment, the bottom of the compression box 32 is provided with a scrap discharge port 3b. In the actual compression process, it is inevitable that some dust will not be compressed. By setting the scrap discharge port 3b, the uncompressed dust can be discharged in real time, avoiding the dust remaining in the compression box 32.

[0025] In this embodiment, the lower ends of the second cylinder 36 and the third cylinder 37 are each provided with a support rod 3c. One end of the two support rods 3c is connected to the frame 31, and the other end is respectively connected to the second The cylinder block of the cylinder 36 and the third cylinder 37. By providing the support rod 3c, the stability of the second cylinder 36 and the third cylinder 37 can be ensured, and the compression quality can be improved.
