Description

Technical Field

[0001] This utility model relates to the field of mixing machine technology, and more specifically, to a dust recovery and utilization device for a mixing machine. Background Technology

[0002] A mixer is a machine used to mix materials. It consists of a horizontally rotating container and rotating vertical stirring blades. It has the advantages of relatively uniform and loose mixing, very few dead corners, convenient discharge, easy cleaning, high production efficiency, and low wear and tear. When the mixer is working, the powdery materials being mixed will generate a certain amount of dust that escapes outward through the feed hopper. This not only causes air pollution but also wastes the resources of the mixed materials. Therefore, a dust recovery and utilization device for mixers is needed.

[0003] The prior art discloses a recycling device for a mixing machine, with publication number CN212216554U. The device includes a mixing machine with a hopper at its upper end. The hopper has a frustum-shaped structure and four through slots. Each through slot contains a powder-absorbing box. The powder-absorbing box and the through slots have interconnected insertion holes, through which one end of a connecting tube is inserted. The other end of the connecting tube is connected to the suction port of a vacuum cleaner, and the connecting tube is a flexible hose. This recycling device for the mixing machine includes a vacuum cleaner. The vacuum cleaner, through the connecting tube, acts on the through slots to form a suction structure. This structure allows dust generated during the feeding process to be directly sucked into the vacuum cleaner, facilitating the recycling of the dust and avoiding environmental pollution. Furthermore, the number of through slots increases the suction area of ​​the dust, resulting in better absorption and higher efficiency.

[0004] When in use, the above-mentioned utility model uses a vacuum cleaner, a connecting pipe, and a dust collection box to perform negative pressure suction and recovery of raw material dust scattered in the feed hopper. However, the connection and installation of the dust collection box and the connecting pipe is relatively cumbersome, and the vacuum cleaner requires a separate power source to drive it, which increases the power consumption of the equipment during operation, thereby increasing the cost of dust recovery in the mixing machine. Its practicality is relatively limited. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a dust recovery and utilization device for a mixing machine, which has the following beneficial effects:

[0016] (1) This utility model is provided with a mixing machine body, a feeding hopper, and a recycling box. The mixing machine body is mounted on the frame, and a stirring shaft is installed in the center of the inner cavity of the mixing machine body. Several stirring blades are evenly fixedly installed on the stirring shaft. In addition, one end of the stirring shaft is connected to the output end of a servo motor and a reducer. On the other hand, a recycling box is fixedly installed on one side of the frame. An installation plate is fixedly installed in the inner cavity of the recycling box, and several dust filters are evenly fixedly installed on the installation plate. An exhaust fan is installed at one end of the stirring shaft in the inner cavity of the recycling box, and the exhaust fan has an exhaust pipe installed on the side wall of the recycling box. The top of the inner cavity of the mixing machine body is connected to the feeding hopper, and a dust extraction chamber is opened in the inner wall of the feeding hopper. Several dust suction holes are evenly opened between the dust extraction chamber and the inner cavity of the feeding hopper. In addition, one side of the dust extraction chamber is connected to the feeding hopper. The device is connected to a connecting pipe, with the other end of the pipe connected to the inner cavity of the recycling bin. During use, the control panel activates the servo motor to rotate the stirring shaft. When the materials to be mixed are introduced into the main cavity of the mixer through the feed hopper, the stirring blades can mix the materials. Simultaneously, the stirring shaft drives the exhaust fan to rotate. The rotating exhaust fan and exhaust pipe create negative pressure in the recycling bin cavity. At this time, dust escaping from the feed hopper is drawn into the recycling bin cavity through the connecting pipe, dust extraction chamber, and dust suction hole. The dust is then filtered and recycled through a dust filter. This dust recycling device utilizes the mixing shaft of the mixer to drive the exhaust fan to generate negative pressure, thereby achieving the extraction and recycling of dust generated during mixer operation. This reduces the device's power consumption, lowers dust recycling costs, and enhances practicality.

A stirring shaft is symmetrically fixedly mounted on one side of the mounting plate, and a dust removal brush is fixedly mounted on the side wall of the dust removal rod, with the brush abutting against one side of the dust filter. When a large amount of dust is trapped and clogged on the dust filter, the stirring shaft can drive the dust removal rod and brush to rotate. The rotating brush then removes the dust adhering to and clogging the dust filter. The removed dust is collected in the recycling box, ensuring efficient dust recycling. A weighing sensor is installed at the bottom of the recycling box. When the collected dust reaches a certain weight, the weighing sensor can detect the signal. Feedback to the control panel allows the buzzer to sound an alarm, reminding workers to replace the recycling bin. To replace the bin, workers simply open the hinged, sealed door and remove the bin. The operation is simple and convenient. When not in use, workers can rotate the adjusting screw using the adjusting knob. The screw is threaded into a sleeve, and its bottom is connected to a baffle frame embedded in the dust extraction chamber. Rotating the screw moves the baffle frame downwards until it blocks the suction hole, isolating the dust extraction chamber from the external environment and preventing external impurities from entering and causing blockages.

[0034] In one embodiment, a discharge pipe 4 is connected to the bottom surface of the mixing machine body 3, which serves to discharge the mixed material.

[0035] Working Principle: This utility model includes a mixing machine body 3, a feeding hopper 9, and a recycling bin 16. The mixing machine body 3 is mounted on a frame 1, and a stirring shaft 5 is installed in the center of the inner cavity of the mixing machine body 3. Several stirring blades 6 are evenly fixedly installed on the stirring shaft 5. In addition, one end of the stirring shaft 5 is connected to the output end of a servo motor 7 and a reducer 8. On the other hand, the recycling bin 16 is fixedly installed on one side of the frame 1. An installation plate 12 is fixedly installed in the inner cavity of the recycling bin 16, and several dust filters 13 are evenly fixedly installed on the installation plate 12. An exhaust fan 14 is installed at one end of the stirring shaft 5 in the inner cavity of the recycling bin 16, and the exhaust fan 14 has an exhaust pipe 15 installed on the side wall of the recycling bin 16. The mixing machine body 3 contains... A feeding hopper 9 is installed at the top of the chamber, and a dust extraction chamber 23 is provided in the inner wall of the feeding hopper 9. Several suction holes 24 are evenly distributed between the dust extraction chamber 23 and the inner cavity of the feeding hopper 9. A connecting pipe 10 is connected to one side of the dust extraction chamber 23, and the other end of the connecting pipe 10 is connected to the inner cavity of the recovery box 16. In use, the control panel 2 starts the servo motor 7 to drive the stirring shaft 5 to rotate. When the materials to be mixed are introduced into the inner cavity of the mixer body 3 through the feeding hopper 9, the stirring blades 6 can mix the materials. At the same time, the stirring shaft 5 can drive the exhaust fan blades 14 to rotate. By rotating the exhaust fan blades 14 and the exhaust pipe 15, a negative pressure is generated in the inner cavity of the recovery box 16. At this time, the dust extraction chamber 23 and the suction holes 24 can be used to remove dust from the feeding hopper. Nine outward-emitting dust particles are drawn into the inner cavity of the recovery box 16 and then filtered by the dust filter 13 for recycling. This allows a dust recycling device for a mixer to utilize the mixing shaft 5 of the mixer to drive the exhaust fan 14 to generate negative pressure, thereby sucking up and recycling the dust generated during the operation of the mixer. This helps reduce the power consumption of the device, lowers the cost of dust recycling, and enhances its practicality. In addition, this utility model is equipped with a dust cleaning brush 20, a recovery box 21, and a weighing sensor 22. The mixing shaft 5 is symmetrically fixedly mounted on one side of the mounting plate 12 with a dust cleaning rod 11, and a dust cleaning brush 20 is fixedly mounted on the side wall of the dust cleaning rod 11. The dust cleaning brush 20 abuts against one side of the dust filter 13. When a large amount of dust is intercepted and blocked on the dust filter 13, the dust cleaning brush 20 can be used to collect the dust. The stirring shaft 5 drives the cleaning rod 11 and the cleaning brush 20 to rotate. The rotating cleaning brush 20 then cleans and removes the dust adhering to and clogging the dust filter 13. The cleaned dust is collected in the recycling box 21, ensuring efficient dust recovery. A weighing sensor 22 is installed at the bottom of the inner cavity of the recycling box 16. When the dust collected in the recycling box 21 reaches a certain weight, the weighing sensor 22 sends a signal to the control panel 2. The control panel 2 then controls the buzzer 19 to sound an alarm, reminding the worker to replace the recycling box 21. To replace the recycling box 21, the worker simply opens the sealing door 18, which is installed on the recycling box 16 via the hinge 17, and then removes the recycling box 21 for replacement. The operation is simple and convenient. When not in use...The worker can rotate the adjusting screw 26 by adjusting the knob 28. The adjusting screw 26 is threaded into the screw sleeve 25, and the bottom end of the adjusting screw 26 is connected to a baffle frame 27 embedded in the dust extraction chamber 23. Therefore, as the adjusting screw 26 rotates, it moves the baffle frame 27 downward until it blocks the dust extraction hole 24. This isolates the dust extraction chamber 23 from the external environment when not in use, preventing external impurities from entering the dust extraction chamber 23 and causing blockage.
