[0024] As attached Figure 1 As shown, the utility model provides a device for automatic cleaning of polyimide production tools, including a two-stage cleaning device, a cleaning liquid circulation device and a drying box 3;

[0025] The two-stage cleaning device includes an ultrasonic cleaning box 1 and a jet cleaning box 2. The ultrasonic cleaning box 1 is connected to the jet cleaning box 2, and the ultrasonic cleaning box 1 and the jet cleaning box 2 are separated by a primary one-way door 13. The jet cleaning box 2 is connected to the drying box 3, and the jet cleaning box 2 and the drying box 3 are separated by a secondary one-way door 14. The cleaning liquid circulation device is arranged outside the jet cleaning box 2, and the heights of the ultrasonic cleaning box 1, the jet cleaning box 2 and the drying box 3 are reduced successively.

[0026] A cabinet entrance 5 is provided above the ultrasonic cleaning cabinet 1, and the equipment to be cleaned enters the ultrasonic cleaning cabinet 1 through the cabinet entrance 5. An inclined material guide plate 4 is provided inside the ultrasonic cleaning cabinet 1, and the equipment to be cleaned is placed on the inclined material guide plate 4. The bottom end of the first-level one-way door 13 is at the same height as the rear end of the inclined material guide plate 4. When the ultrasonic cleaning is completed, the first-level one-way door 13 is opened and under the action of gravity, the equipment rolls down along the slope of the inclined material guide plate 4 into the spray cleaning cabinet 2.

[0027] The interior of the spray cleaning box 2 is provided with a spray head 12, a vibrating mesh screen 6, a material guide scraper 8 and a water filter port 23. The spray head 12 is arranged in the middle above the spray cleaning box 2 to spray cleaning liquid or hot air into the spray cleaning box 2. The vibrating mesh screen 6 is arranged on the spray cleaning box 2. The vibrating mesh screen 6 is externally connected to a vibrator 7. The vibrator 7 drives the vibrating mesh screen 6 to move, so that the equipment falling on the vibrating mesh screen 6 can be cleaned more fully. The material guide scraper 8 is arranged above the vibrating mesh screen 6. The bottom end of the material guide scraper 8 is in contact with the vibrating mesh screen 6. The top of the material guide scraper 8 is at the same height as the tail end of the inclined material guide plate 4. The slope setting of the material guide scraper 8 can prevent the equipment rolling down from the inclined material guide plate 4 from piling up on the left side of the vibrating mesh screen 6, so that the equipment is more evenly distributed on the vibrating mesh screen 6. The material guide scraper 8 is externally connected to a push-pull handle 9. The bottom end of the secondary one-way door 14 is at the same height as the tail end of the vibrating mesh screen 6. After cleaning, open the secondary one-way door 14, push and pull the handle 9 to drive the material guide scraper 8 to move horizontally, so that the equipment at the vibrating screen 6 can be pushed into the drying box 3, and the water filter port 23 is set at the bottom end of the spray cleaning box 2.

[0028] The cleaning liquid circulation device includes a circulation pump 10, a filter 24 and a discharge pipe 11. The filter 24 is connected to the water filter port 23 of the spray cleaning box 2. The discharge pipe 11 is connected to the injection head 12 of the spray cleaning box 2. The discharge pipe 11 has a one-way valve. When cleaning, the one-way valve is opened, and the circulation pump 10 pumps the cleaning liquid through the discharge pipe 11 to the injection head 12. After cleaning the equipment, the cleaning liquid flows out from the water filter port 23, passes through the filter 24 to process the cleaning liquid, and then re-enters the circulation pump 10 for circulation.

[0029] The drying box 3 includes a water filter net 15, an inclined guide plate 16, a sewage outlet 17, a gas phase outlet 21, a fan 19, a heater 20 and a three-level one-way door 18. The wind blown by the fan 19 is heated by the heater 20 to form warm air, which enters the drying box 3 to dry the equipment at the water filter net 15. The inclined guide plate 16 is arranged below the water filter net 15. The inclined high part of the inclined guide plate 16 is adjacent to the three-level one-way door 18, and the inclined low part of the inclined guide plate 16 is connected to the sewage outlet 17. The water carried out of the equipment from the jet cleaning box 2 leaks from the water filter net 15 to the inclined guide plate 16, and flows out from the sewage outlet 17 through the slope of the inclined guide plate 16. The three-level one-way door 18 is opened to take out the cleaned equipment. The gas phase outlet 21 is arranged at the top of the drying box 3, and the gas phase outlet 21 is connected to the injection head 12 through a connecting pipe 22. A one-way valve is also arranged at the connecting pipe 22. When cleaning is completed, the one-way valve at the discharge pipe 11 is closed, and the one-way valve at the connecting pipe 22 is opened. The warm air passes through the injection head 12 to dry the injection cleaning box 2.

[0030] In the specific implementation process, the vessel to be cleaned is placed in the inclined guide plate 4 of the ultrasonic cleaning box 1 through the machine box inlet 5 of the ultrasonic cleaning box 1, and the ultrasonic cleaning box 1 starts to work. Then, the first-level one-way door 13 is opened, and the vessel is drawn into the spray cleaning box 2 by gravity through the inclined guide plate 4 and the guide scraper 8; (2) the discharge pipe 11 is opened, the circulation pump 10 and the spray head 12 start to work, and the vessel is rinsed. The vibrator 7 drives the vibrating mesh 6 to start working. After the cleaning is completed, the second-level one-way door 14 is opened, and the guide scraper 8 is pushed by the push-pull handle 9 to push the vessel into the drying box 3; (3) the sewage in the drying box 3 is introduced into the sewage outlet 17 through the inclined guide plate 16, and the fan 19 and the heater 20 start to work to dry the vessel. The dried gas phase is introduced into the spray cleaning box 2 through the connecting pipe 22 to dry it.

[0031] Therefore, the utility model adopts the above-mentioned equipment for automatic cleaning of polyimide production tools to solve the problem that the existing device directly rinses the utensils, has low efficiency, and is difficult to clean and dry the inside of the cleaning box.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
