Description

Technical Field

[0001] This utility model relates to the field of paint waste technology, and in particular to a high-efficiency grinding and treatment equipment for harmless waste. Background Technology

[0002] During the coating process, the effective utilization rate of coatings is relatively low. The effective utilization rate of air spraying is only 30-40%, and the effective utilization rate of high-pressure airless spraying is only 50-60%, resulting in a lot of waste. Furthermore, the collected coating wastewater will generate a large amount of coating waste residue after flocculation and sedimentation, which will cause great harm to the environment.

[0003] Announcement No. CN220028182U discloses a paint waste recycling device. The device involves starting a first motor to drive a stirring shaft, which, in conjunction with a stirring rod, stirs the pulverized paint waste and surface modifier, ensuring thorough mixing to obtain modified paint waste. Then, the solenoid valve on the discharge pipe is opened, allowing the modified paint waste to fall into a recycling bin, facilitating its recycling. This practical device is suitable for widespread promotion and use.

[0004] However, during the implementation of this device, after the paint waste is put into the grinding box, the paint waste falls directly downwards and comes into contact with the grinding roller. As a result, the paint waste cannot be in contact with the heating plate for a long enough time, which means that the paint waste cannot be completely dried. As a result, the paint waste will still adhere to the surface of the grinding roller, affecting the grinding of the grinding roller. Therefore, a harmless and efficient grinding treatment device for waste is proposed to solve the above problems. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a high-efficiency grinding and treatment device for harmless waste residue, including a fixed frame 1, a crushing box 2 fixedly connected to the upper end of the fixed frame 1, two grinding rollers 16 rotatably connected inside the crushing box 2, and a heating plate installed inside the crushing box 2. The waste residue coating is crushed by the rotation of the two grinding rollers 16, and the waste residue coating is dried in conjunction with the heating plate. (This is described in a comparative example and will not be explained further.) A processing tank 6 is mounted inside the fixed frame 1, a feed hopper 3 is fixedly connected to the upper end of the crushing box 2, and a guide plate 9 is fixedly connected inside the crushing box 2. The guide plate 9 is inclined, and two rotating frames 7 are rotatably connected inside the crushing box 2. The surfaces of the two rotating frames 7 are in contact with the surface of the guide plate 9, and the surfaces of the rotating frames 7 are arc-shaped. The two rotating frames 7 are used to block the sliding paint waste, thereby preventing the paint waste from sliding directly downward. The mounting shafts of the two rotating frames 7 extend to the outside of the crushing box 2. A sprocket set 20 is provided on the mounting shafts of the two rotating frames 7. A motor 5 is fixedly connected to the surface of the crushing box 2. The output end of the motor 5 is fixedly connected to the mounting shaft of one of the rotating frames 7 through a coupling.

[0025] A protective shell 4 is fixedly connected to the surface of the crushing box 2. The output end of the motor 5 is rotatably connected to the inside of the protective shell 4. The sprocket assembly 20 is located inside the protective shell 4. The protective shell 4 covers the sprocket assembly 20, thereby shielding and protecting the sprocket assembly 20.

[0026] A fixed shell 8 is fixedly connected to the surface of the guide plate 9. The interior of the fixed shell 8 is rotatably connected to the surface of the mounting shaft of the rotating frame 7. A rotating disk 18 is fixedly connected to the surface of the mounting shaft of the rotating frame 7 inside the fixed shell 8, and the surface of the rotating disk 18 is provided with teeth. A sliding rod 10 is slidably connected inside the fixed shell 8, and the sliding rod 10 passes through the guide plate 9 and is slidably connected to its interior. A mounting plate 11 is fixedly connected to one end of the sliding rod 10 outside the fixed shell 8. A striking block 12 arranged at equal intervals is fixedly connected to the side of the mounting plate 11 near the guide plate 9. A second spring 19 is fixedly connected inside the fixed shell 8, and the end of the second spring 19 away from the fixed shell 8 is fixedly connected to the sliding rod 10.

[0027] The crushing box 2 has a sliding plate 13 inside, which is inclined. A drive rod 14 is fixedly connected to the surface of the sliding plate 13. A guide plate 15 is fixedly connected inside the crushing box 2, which is inclined.

[0028] A first spring 17 is fixedly connected inside the crushing box 2. The end of the first spring 17 away from the crushing box 2 is fixedly connected to the sliding plate 13. The sliding of the sliding plate 13 is controlled by the setting of the first spring 17.

[0029] Working principle: When paint waste needs to be processed, the paint waste is fed into the crushing box 2 from the feed hopper 3. At the same time, the operator starts the motor 5. The output end of the motor 5 drives the rotating frame 7 connected to it to rotate. The rotating frame 7 then drives the sprocket group 20 to rotate. The sprocket group 20 then drives the rotating frame 7 not connected to the motor 5 to rotate, so that the two rotating frames 7 rotate simultaneously. Due to the arc-shaped design of the rotating frame 7, the rotating frame 7 rotates and conveys the paint waste. By adjusting the rotation speed of the motor 5, the rotation speed of the rotating frame 7 can be controlled, and the residence time of the paint waste can be controlled, so that the heating plate can bake the paint waste evenly.

[0030] When the rotating frame 7 rotates, the mounting shaft of the rotating frame 7 drives the rotating disk 18 to rotate. The groove on the surface of the rotating disk 18 then presses against the surface of the sliding rod 10, causing the sliding rod 10 to slide under force. At the same time, the sliding rod 10 causes the second spring 19 to deform, and the sliding rod 10 pushes the mounting plate 11 to move. The mounting plate 11 then drives the striking block 12 to move. As the rotating disk 18 rotates, when the sliding rod 10 corresponds to another groove on the rotating disk 18, under the elastic force of the second spring 19, the sliding rod 10 drives the mounting plate 11 and the striking block 12 to move and collide with the bottom of the guide plate 9, causing the guide plate 9 to vibrate. As a result, the paint waste on the surface of the guide plate 9 can slide off smoothly, avoiding the accumulation of paint waste on the surface of the guide plate 9.

[0031] When the mounting plate 11 moves, it pushes the drive rod 14, which in turn pushes the sliding plate 13. The sliding plate 13 causes the first spring 17 to deform. When the mounting plate 11 moves upward and separates from the drive rod 14, the sliding plate 13 pushes the drive rod 14 to vibrate under the elastic force of the first spring 17. The sliding plate 13 then transports the paint waste that slides down the guide plate 9. With the help of the guide plate 15, the paint waste is gathered, and the grinding roller 16 crushes the paint waste. The crushed paint waste enters the lower processing tank 6 for stirring and neutralization, and is then rendered harmless for subsequent processing.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
