Description

Technical Field

[0001] This utility model relates to the field of color sorter technology, specifically to a dust collection device for a color sorter. Background Technology

[0002] A color sorter is a device that automatically separates discolored particles from granular materials based on differences in their optical properties using photoelectric detection technology.

[0003] The prior art discloses a dust collection device for a color sorter, application number CN202323041549.9. This device includes a guide member with a collection groove inside. A motor is mounted on the right side of the guide member, and a fan is mounted on the left side. A dust collection mechanism for the color sorter is located within the guide member. This invention, upon starting the fan, generates an airflow path of multiple fine holes → hollow plate → hose → filter box. This draws in a large amount of dust generated during the agitation process, along with the mixture of corn germ and corn kernels, which is then drawn into the hollow plate through the fine holes and finally into the filter box. The dust is filtered by multiple filter screens and retained on the screens. Because the hollow plate moves back and forth, the dust collection effect is improved, reducing dust on the surface of the corn germ and corn kernel mixture.

[0004] The above-mentioned method of using a fan to vacuum the contents of the guide component requires the hollow plate to move left and right to absorb the dust inside the guide component. This causes dust far from the hollow plate to escape, requiring additional time to deal with the escaped dust. Utility Model Content

[0011] Preferably, the connecting rod is located inside the helical spring, and the limiting metal plate and the connecting rod are threaded together, so that the helical spring can be compressed between the connecting rod and the limiting metal plate, making it convenient to disassemble and replace the limiting metal plate.

[0012] Preferably, the metal support frame is slidably connected to the inner wall surface of the filter housing, and the metal support frame and the filter housing can clamp and fix the filter plate, which can prevent the filter plate from shaking and thus increase the service life of the filter plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A dust collection device for a color sorter includes a dust removal device 1 and a storage cabinet 2. A scraper 3 is installed on the upper end of the storage cabinet 2, and a screening screen 4 is installed on the upper end of the inner wall surface of the storage cabinet 2. The storage cabinet 2 is installed on the upper end of the dust removal device 1.

[0026] The dust removal device 1 includes a support frame 11, an exhaust fan 12, and a filter assembly 13. The exhaust fan 12 is installed at the lower end of the support frame 11 and at the bottom surface of the filter assembly 13.

[0027] The filter assembly 13 includes a filter housing 131, a metal support frame 132, a filter plate 133, a connecting housing 134, a connecting rod 135, a coil spring 136, and a limiting metal plate 137. The filter plate 133 is inserted into the inner wall surface of the filter housing 131. The filter housing 131 is movably connected to the bottom surface of the storage cabinet 2. The connecting housing 134 is movably connected to the bottom surface of the filter housing 131. A threaded rod is fixedly connected to the bottom surface of the storage cabinet 2. The threaded rod is threadedly connected to the upper end of the connecting housing 134. The threaded rod can thread-fix the connecting housing 134 and the filter housing 131, facilitating the disassembly and replacement of the filter housing 131 and the connecting housing 134. The filter plate 133 is threaded... The metal support frame 132 is slidably connected to the inner wall surface of the filter housing 131. The metal support frame 132 and the filter housing 131 clamp and fix the filter plate 133, preventing it from shaking and thus increasing its service life. The metal support frame 132 is fixedly connected to the top surface of the connecting housing 134. The connecting rod 135 is threaded to the upper end of the support frame 11 and inserts into the upper end of the support frame 11, thereby determining the position of the limiting metal plate 137. This allows the position of the connecting housing 134 to be determined. The limiting metal plate 137 is movably connected to the bottom surface of the connecting housing 134. The exhaust fan 12 is installed on the bottom surface of the connecting housing 134. The connecting housing 134 consists of a metal housing and a connecting hose. The hose is connected to the top surface of the exhaust fan 12, thereby enabling the dust removal operation of objects inside the storage cabinet 2. The limiting metal plate 137 is threadedly connected to the lower end of the connecting rod 135. The limiting metal plate 137 is installed on the bottom surface of the coil spring 136. The connecting rod 135 is located inside the coil spring 136. The limiting metal plate 137 and the connecting rod 135 are threadedly connected, thereby allowing the connecting rod 135 and the limiting metal plate 137 to compress the coil spring 136, making it convenient to disassemble and replace the limiting metal plate 137.

[0028] When in use, push the filter housing 131 upward so that the filter housing 131 is inserted into the lower end of the storage cabinet 2, thereby determining the position of the filter housing 131.

[0029] The connecting housing 134 is pushed upward, which in turn pushes the metal support frame 132 upward, and the metal support frame 132 pushes the filter plate 133 upward, so that the filter plate 133 and the metal support frame 132 can move upward along the inner wall of the filter housing 131.

[0030] The threaded rod connecting the outer shell 134 and the storage cabinet 2 slides, and then the nut is rotated. The nut rotates on the surface of the threaded rod, thereby fixing the threads connecting the outer shell 134, the filter shell 131 and the storage cabinet 2, thereby determining the position of the filter plate 133.

[0031] Push the connecting rod 135 upward, and the connecting rod 135 will be inserted into the upper end of the support frame 11. Then rotate the nut, which will thread the connecting housing 134 and the support frame 11 together.

[0032] Pushing the helical spring 136 upwards causes the upper end of the helical spring 136 and the connecting rod 135 to be movably connected, thereby determining the position of the connecting rod 135.

[0033] Pushing the limiting metal plate 137 upward, the limiting metal plate 137 slides on the surface of the connecting rod 135, so that the coil spring 136 can be compressed between the coil spring 136 and the limiting metal plate 137.

[0034] When the limiting metal plate 137 moves upward, it can slide on the surface of the connecting housing 134. At the same time, a threaded rod is provided in the middle of the connecting housing 134. The threaded rod can pass through the middle position of the limiting metal plate 137. Then, by rotating the nut, the connecting housing 134 can be connected and the limiting operation can be performed.

[0035] Rotating the nut causes it to rotate on the threaded surface of the connecting rod 135, thereby enabling the limiting metal plate 137 to be used for secondary limiting operations.

[0036] Start the exhaust fan 12, and connect the exhaust fan 12 to the inner flexible hose in the connecting housing 134 to perform dust extraction on the selected objects inside the storage cabinet 2. The extracted dust passes through the filter plate 133, thereby filtering the gas.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
