Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a cleaning gun device that can recycle cleaning solvent. Background Technology

[0002] Multiple cleaning processes are required between each step of the process of applying primer, color paint, and clear coat to automotive parts. This process is crucial for ensuring coating quality, adhesion, and appearance.

[0003] The tool used in the cleaning process is a spray gun. After prolonged use, material residue will remain at the nozzle of the spray gun. If it is not cleaned in time, it will cause the nozzle to become clogged, resulting in inconsistent spraying effects.

[0004] Currently, the factory uses a gun cleaning box to clean the spray guns, which generates a large amount of waste solvent each month. As a result, the monthly cleaning process of primer, color paint, and clear coat requires the use of about 5 tons of fresh solvent. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a gun washing device that can filter and recycle waste solvent inside the gun washing box and recycle the cleaning solvent.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a gun washing device that can recycle cleaning solvent, the innovation of which is: including A gun cleaning box, wherein a drain outlet is provided at the bottom of the gun cleaning box; A recycling bin is provided at the bottom of the gun washing box, and a liquid inlet is provided at the top of the recycling bin; A conveying and filtering pipeline is installed at the drain port and the inlet port.

[0007] Furthermore, the conveying and filtering pipeline includes two vertically arranged pipes, and a filter plate is installed between the two pipes.

[0008] Furthermore, the filter plate includes a plate body and a filter screen; The plate includes a body, which is formed by cutting off half of the annular segment from the outside of an annular structure. From the outside to the inside, it consists of a large semicircular arc segment and a small annular segment. The outer diameter of the large semicircular arc segment is the same as the outer diameter of the pipe, and the outer diameter of the small annular segment is equal to the inner diameter of the pipe. The filter screen is installed in the lower middle part of the inner side of the small annular section, which can reserve more space for the filtered impurities and avoid the situation where the filter plate cannot be smoothly detached from the two pipes. The top and bottom surfaces of the plate are each provided with a semi-circular annular sealing groove at the large semi-circular arc segment. This semi-circular annular sealing groove overlaps with the center of the large semi-circular arc segment. Each side of the plate at the large semi-circular arc segment is provided with a side sealing groove, and each side sealing groove communicates with two semi-circular annular sealing grooves. A first sealing strip is provided within the semi-circular annular sealing groove and the side sealing groove on the top surface of the plate, and a second sealing strip is provided within the semi-circular annular sealing groove and the other side sealing groove on the bottom surface of the plate. The first and second sealing strips ensure a tight seal between the filter plate and the upper and lower pipes.

[0012] Furthermore, an arc-shaped limiting baffle is provided on the side of the upper pipe and the lower pipe away from the semi-circular annular groove, and the limiting baffle is fixedly installed on the outer wall of the upper pipe. An arc-shaped sealing groove is also provided on the inner wall of the arc-shaped limiting baffle. A third sealing strip is provided in the arc-shaped sealing groove, and the third sealing strip covers the docking side of the upper and lower pipes, thereby achieving sealing treatment between the upper and lower pipes.

[0013] The advantages of this utility model are: In this structure, the recycling bin is moved toward the opening of the limiting baffle below the gun washing box until the lower pipe extends into the arc-shaped limiting baffle and stops. Then, the recycling bin is rotated to adjust the position of the second arc-shaped groove of the lower pipe.

[0026] The conveying filter pipe 3 is connected and installed at the drain port and the inlet port.

[0027] The conveying and filtering pipeline 3 includes two vertically arranged pipelines and an arc-shaped limiting baffle 33, and a filter plate 34 is installed between the two pipelines. The distance between the drain port and the inlet port is equal to the sum of the lengths of the two pipelines.

[0028] The filter plate 34 is horizontally arranged and includes a plate body 341, a filter screen 342 and a hand plate 343.

[0029] The plate 341 includes a body, which is formed by cutting off a semi-circular segment of equal height from the outside of a circular ring structure. From the outside to the inside, the body consists of a large semi-circular arc segment 3411 and a small circular ring segment 3412. The outer diameter of the large semi-circular arc segment 3411 is the same as the outer diameter of the pipe, and the outer diameter of the small circular ring segment 3412 is equal to the inner diameter of the pipe.

[0030] The filter screen 342 is installed horizontally at the lower center of the inner side of the small annular section 3412, which can reserve more space for the filtered impurities and prevent the filter plate 34 from being unable to detach smoothly from the two pipes.

[0031] A hand-held plate 343 is also fixedly installed on the outer middle part of the semi-circular arc section 3411 on the plate 341, which facilitates installation and removal.

[0032] The top and bottom surfaces of the plate 341 are provided with semi-circular annular sealing grooves 3413 at the semi-circular arc section 3411.

The plate 341 is provided with one-sided sealing grooves 3414 at the two sides 3418 of the semi-circular arc section 3411. Each side sealing groove 3414 is connected to two semi-circular annular sealing grooves 3413. A first sealing strip 3416 is provided in the semi-circular annular sealing groove 3413 and the one-sided sealing groove 3414 on the top surface of the plate 341. A second sealing strip 3417 is provided in the semi-circular annular sealing groove 3413 and the other side sealing groove 3414 on the bottom surface of the plate 341.

[0033] The two pipes are an upper pipe 31 installed at the drain outlet and a lower pipe 32 installed at the inlet. The bottom front side of the upper pipe 31 is provided with a first arc-shaped groove. The bottom end of the upper pipe 31 is successively a front upper horizontal section, a first middle vertical section 34 and a rear lower horizontal section. The top front side of the lower pipe 32 is provided with a second arc-shaped groove. The top end of the lower pipe 32 is a front lower horizontal section, a second middle vertical section 35 and a rear upper horizontal section. The first arc-shaped groove and the second arc-shaped groove form a semi-circular annular groove 33 that can just accommodate the semi-circular arc-shaped section 3411 extending into it. The height of the semi-circular annular groove 33 is equal to the height of the plate 341.

[0034] When the lower pipe 32 moves to the bottom of the upper pipe 31 along with the recycling bin 2, the lower rear horizontal section of the upper pipe 31 and the upper rear horizontal section of the lower pipe 32 are closely fitted together.

[0035] The connection and sealing between the plate 341 and the semi-circular annular groove 33 can be achieved through the first sealing strip 3416 and the second sealing strip 3417, thereby achieving a sealed connection between the filter plate 34 and the upper pipe 31 and the lower pipe 32.

[0036] On the plate 341, a locking block 3415 is provided on the side of the small annular segment 3412 away from the large semicircular arc segment 3411. A slot is provided between the upper pipe 31 and the lower pipe 32 to accommodate the locking block 3415. The horizontal setting of the filter plate 34 is achieved by the cooperation of the locking block 3415 and the slot.

[0037] That is, a first snap-fit ​​groove is provided on the bottom of the rear inner wall of the upper pipe 31, and a second snap-fit ​​groove is provided on the top of the rear inner wall of the lower pipe 32. When the upper and lower pipes 32 are closely adjacent, the first snap-fit ​​groove and the second snap-fit ​​groove are connected to form a snap-fit ​​groove.

[0038] An arc-shaped limiting baffle 33 is provided on the rear side of the upper pipe 31 and the lower pipe 32. The limiting baffle 33 is fixedly installed on the outer wall of the upper pipe 31, and the inner wall of the arc-shaped limiting baffle 33 is set close to the outer wall of the upper pipe 31.

[0039] An arc-shaped sealing groove is provided on the inner wall of the arc-shaped limiting baffle 33 at the contact side of the upper pipe 31 and the lower pipe 32. A third sealing strip 36 is provided in the arc-shaped sealing groove. The third sealing strip 36 is also designed in an arc shape, and the two sides of the third sealing strip 36 extend to the two sides 3418 of the semi-circular arc section 3411.

[0040] The third sealing strip 36 can completely cover the space between the lower rear horizontal section of the upper pipe 31 and the upper rear horizontal section of the lower pipe 32, thereby achieving a sealing treatment between the filter plate 34 and the upper and lower pipes 32.

[0041] The working principle of this patent: Position the second arc-shaped groove of the lower pipe 32 on the recycling bin 2 facing forward. Then move the recycling bin 2 toward the opening of the limiting baffle 33 of the upper pipe 31 until the lower pipe 32 extends into the arc-shaped limiting baffle 33. Then rotate the recycling bin to adjust the second arc-shaped groove of the lower pipe 32 to align with the first arc-shaped groove of the upper pipe 31. Continue moving the recycling bin 2 until the outer wall of the lower pipe 32 is flush against the inner wall of the arc-shaped limiting baffle 33. At this point, the second arc-shaped groove and the first arc-shaped groove form a semi-circular annular groove 33, and the rear lower horizontal section of the upper pipe 31 is flush against the rear upper horizontal section of the lower pipe 32. Figure 4 As shown, the filter plate 34 is then held by the hand plate 343, and inserted into the upper and lower pipes 32 through the semi-circular groove 33. The filter plate 34 is then positioned by the cooperation of the locking block 3415 and the locking groove. The waste solvent inside the cleaning gun box 1 can then enter the conveying and filtering pipe 3 from the drain port, and after being filtered by the filter plate 34, it is sent to the recycling bin 2 for recycling. This process can filter out various heavy metals or other solid impurities contained in the waste solvent, making it easier to distill and reuse the filtered and recycled waste solvent. This reduces the amount of fresh solvent used, thereby reducing the factory's production costs.
