Description

Technical Field

[0001] The utility model relates to the technical field of paint recovery, in particular to a paint recovery and cleaning device. Background Art

[0002] Paint storage barrels are mainly used to store and transport paint. Due to the stickiness of the paint, after the paint in the storage barrel is used up, some paint will still adhere to the inner wall of the paint storage barrel. The paint storage barrel is generally discarded directly after use, resulting in the waste of some of the remaining paint in the paint storage barrel, which will also pollute the environment. Utility Model Content

[0003] The purpose of the utility model is to provide a paint recovery and cleaning device to overcome the above-mentioned defects in the prior art.

[0004] According to the paint recovery and cleaning device of the utility model, it includes a collecting seat, a water inlet pipe is fixedly provided on the lower end surface of the collecting seat, a one-way valve is installed in the upper end of the water inlet pipe, a rotating shaft is provided on the upper side of the collecting seat, and a symmetrically arranged straight scraper is fixedly provided on the upper end of the rotating shaft, and two straight scrapers are fixed with an arc-shaped scraper at one end away from the rotating shaft, the two straight scrapers can abut against the bottom wall of the paint storage bucket, and the two arc-shaped scrapers can abut against the side wall of the paint storage bucket.

[0005] Through the above-mentioned technical scheme, the rotating shaft rotates, so that the two straight scrapers rotate to scrape off the residual paint on the bottom wall of the paint storage bucket. At the same time, the two arc scrapers rotate to scrape off the residual paint on the side wall of the paint storage bucket to reduce the waste of paint, and then high-pressure water flow is sprayed to the inner wall of the paint bucket through the water inlet pipe to clean the inner wall of the paint storage bucket.

[0006] Furthermore, the two arc-shaped scrapers are symmetrically arranged with the rotating shaft as the center, and the two arc-shaped scrapers are gradually lowered downward along their peripheral direction.

[0007] Through the above technical solution, the two arc-shaped scrapers are arranged obliquely, so that the residual paint on the side wall of the paint storage bucket can be scraped downward along the arc-shaped scrapers.

[0008] Furthermore, the two arc-shaped scrapers are both made of rubber, and the curvature of the two arc-shaped scrapers is smaller than the curvature of a circle formed with the straight scraper as the radius.

[0009] Through the above technical solution, since the two curved scrapers made of rubber are elastic, the two curved scrapers can be closely abutted against the inner wall of the paint bucket, thereby improving the paint scraping effect.

[0010] Furthermore, a guide cavity recessed upward is provided in the lower end surface of each straight scraper, and the two guide cavities are symmetrically arranged with the rotating shaft as the center, and each guide cavity extends outwardly through the arc scraper on the corresponding side.

[0011] Through the above technical solution, under the guiding effect of the two guide chambers, the residual paint on the bottom wall of the paint storage bucket is easy to flow downward after being scraped off.

[0012] Furthermore, the edges formed between the two guide cavities and the upper end surfaces of the straight scrapers on the corresponding sides are covered with linings, and the two linings are symmetrical with the rotating shaft as the center.

[0013] Through the above technical solution, since the edge formed between the two guide cavities and the straight scrapers on the corresponding sides is thinner, the scraping effect of residual paint on the bottom wall of the paint storage barrel is improved, and the lining can prevent the straight scrapers from scratching the bottom wall of the paint storage barrel.

[0014] Furthermore, a collecting chamber with an opening facing upward is provided in the collecting seat, and the upper end of the water inlet pipe can be connected to the collecting chamber through the one-way valve.

[0015] Through the above technical solution, when the one-way valve is opened, the water inlet pipe can spray high-pressure water into the paint storage barrel. When the one-way valve is closed, when the residual paint gathers in the collection chamber, the paint will not flow into the water inlet pipe through the one-way valve.

[0016] Furthermore, a discharge pipe is fixed to the lower end surface of the collecting seat, the bottom wall of the collecting cavity is a conical surface, and the upper end of the discharge pipe is located at the lowest point of the bottom wall of the collecting cavity and is connected to the collecting cavity.

[0017] Through the above technical solution, the conical surface of the bottom wall of the collecting chamber facilitates the collection of wastewater generated after paint or cleaning, and discharges it from the discharge pipe.

[0018] Furthermore, the lower end of the rotating shaft is rotatably installed in the collecting seat, the rotating shaft coincides with the axis of the collecting seat, a motor is fixed to the lower end surface of the collecting seat, and the lower end of the rotating shaft is drivingly connected to the output shaft of the motor.

[0019] Through the above technical solution, the motor drives the rotating shaft to rotate, so that the straight scraper and the arc scraper can rotate to scrape off the residual paint in the paint storage bucket.

[0020] The beneficial effect of the utility model is that the straight scraper and the arc scraper are driven to rotate by the motor, so that the residual paint attached to the inner wall of the paint storage barrel can be scraped off, so that the residual paint falls downward into the collecting chamber, and is collected through the bottom wall of the collecting chamber and discharged through the discharge pipe for unified collection, thereby reducing the waste of paint and the sewage generated by subsequent cleaning. Then, a high-pressure water flow is sprayed into the paint storage barrel through the water inlet pipe, thereby cleaning the paint storage barrel and avoiding the residual paint in the paint storage barrel from polluting the environment.

[0030] An embodiment of the utility model:

[0031] Reference Figure 1-Figure 5 The utility model provides a paint recovery and cleaning device, including a collecting seat 10, a water inlet pipe 13 is fixedly provided on the lower end surface of the collecting seat 10, a one-way valve 20 is installed in the upper end of the water inlet pipe 13, a rotating shaft 11 is provided on the upper side of the collecting seat 10, and a symmetrically arranged straight scraper 16 is fixedly provided on the upper end of the rotating shaft 11, and an arc-shaped arc scraper 18 is fixed on the two straight scrapers 16 away from the rotating shaft 11. The two straight scrapers 16 can abut against the bottom wall of the paint storage bucket, and the two arc scrapers 18 can abut against the side wall of the paint storage bucket. The two arc scrapers 18 are symmetrically arranged with the rotating shaft 11 as the center. The two arc scrapers 18 are gradually lowered downward along the peripheral direction thereof. The two arc scrapers 18 are made of rubber. The two arc scrapers 18 are elastic, so that the two ends of the two arc scrapers 18 are closely abutted against the inner wall of the paint bucket outward. The curvature of the two arc scrapers 18 is smaller than the curvature of the circle formed by the straight scraper 16 as the radius. A guide cavity 19 recessed upward is provided in the lower end surface of each straight scraper 16. The two guide cavities 19 are symmetrically arranged with the rotating shaft 11 as the center. Each guide cavity 19 extends outwardly through the arc scraper 18 on the corresponding side. The edges between the two guide cavities 19 and the upper end surfaces of the straight scrapers 16 on the corresponding sides are covered with linings 17. The linings 17 are made of rubber material to prevent the straight scrapers 16 from scratching the inner wall of the storage barrel, thereby causing metal debris to be integrated into the paint and contaminating the paint. The two linings 17 are symmetrical around the rotating shaft 11. A collecting cavity 12 with an opening upward is provided in the collecting seat 10. The upper end of the water inlet pipe 13 can be connected to the collecting cavity 12 through a one-way valve 20.

[0032] Reference Figure 2 A discharge pipe 15 is fixed to the lower end surface of the collecting seat 10, and the bottom wall of the collecting chamber 12 is a conical surface. The upper end of the discharge pipe 15 is located at the lowest point of the bottom wall of the collecting chamber 12 and is connected to the collecting chamber 12. The lower end of the rotating shaft 11 is rotatably installed in the collecting seat 10, and the axis of the rotating shaft 11 coincides with the axis of the collecting seat 10. A motor 14 is fixed to the lower end surface of the collecting seat 10, and the lower end of the rotating shaft 11 is drivingly connected to the output shaft of the motor 14, and the lower end of the water inlet pipe 13 is connected to the water pump.

[0033] The paint storage bucket that has been used up is turned upside down, and the open end of the paint storage bucket is inserted into the collecting seat 10, the two straight scrapers 16 abut against the bottom wall of the paint storage bucket, and the two arc scrapers 18 abut against the side wall of the paint storage bucket.

[0034] At this time, starting the motor 14 can drive the rotating shaft 11 to rotate, thereby causing the two straight scrapers 16 and the two curved scrapers 18 to rotate, thereby scraping off the residual paint on the bottom wall and side walls of the paint storage barrel. During the scraping process, the paint storage barrel is moved up and down, so that the two curved scrapers 18 can scrape off all the residual paint on the side walls of the paint storage barrel, allowing the residual paint to flow downward to the collecting chamber 12 and gather at the discharge pipe 15, and be discharged through the discharge pipe 15. Placing a paint collecting bucket under the discharge pipe 15 can collect the residual paint.

[0035] After the paint collection is completed, the paint collection bucket is removed and a sewage collection bucket is placed under the discharge pipe 15 .

[0036] At this time, the water pump is started, and the water flows upward through the water inlet pipe 13 and the one-way valve 20 to spray high-pressure water flow, thereby cleaning the paint that has not been cleaned out in the paint storage barrel. The sewage generated by cleaning is collected through the collection chamber 12 to the discharge pipe 15 and discharged downward into the sewage collection barrel through the discharge pipe 15.

[0037] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
