[0031] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation manners.

[0032] Unless otherwise clearly stated, in the whole specification and claims, the term "comprising" or its variations such as "comprises" or "including" etc. will be understood to include the stated elements or components, without excluding other elements or other components. Embodiment 1:

[0033] Refer Figures 1-11 As shown in the figure, a paint waste liquid processor according to an embodiment of the present invention includes a main body 1 of waste liquid processor, a filter box 4, a waste liquid filtering device 7, a third infusion pipe 8 and a barrel cleaning device 3. An installation groove 101 is provided on the main body 1 of waste liquid processor. The barrel cleaning device 3 rotates on the top of the main body 1 of waste liquid processor. The barrel cleaning device 3 is used for brushing the paint barrel. The main body 1 of waste liquid processor is used for loading the waste liquid generated during the process of the barrel cleaning device 3 brushing the paint barrel. The waste liquid filtering device 7 can also filter the paint waste liquid generated by cleaning the paint barrel, so as to facilitate the reuse of the filtered waste liquid through the third infusion pipe 8.

[0034] Specifically, refer Figure 7 As shown in the figure, the barrel cleaning device 3 includes a cleaning barrel 301 and a cleaning column 302. Cleaning parts 11 matching the paint barrel are fixedly connected to both the cleaning barrel 301 and the cleaning column 302. The cleaning barrel 301 includes a base and a convex part, and the base and the convex part are integrally formed. The paint barrel is buckled on the cleaning column 302. The cleaning part 11 installed on the cleaning column 302 contacts the inner wall of the paint barrel, and the cleaning part 11 installed on the cleaning barrel 301 contacts the outer wall of the paint barrel.

[0035] Among them, S1 is a paint bucket.

[0036] See Figure 7 As shown, a transmission block 304 is rotatably connected to the outside of the base. The transmission block 304 can drive the cleaning column 302 to rotate. A pair of connecting rods 303 are welded on the transmission block 304, and the pair of connecting rods 303 are arranged oppositely. This enables the cleaning column 302 to rotate relatively stably on the transmission block 304. The upper end of the waste liquid processor main body 1 is fixedly connected with a motor 2 that matches the cleaning bucket 301, and the motor 2 can drive the cleaning bucket 301 to rotate.

[0037] Among them, the direction in which the transmission block 304 drives the cleaning column 302 to rotate is opposite to the direction in which the motor 2 drives the cleaning bucket 301 to rotate, so that the paint bucket is located between the cleaning bucket 301 and the cleaning column 302, with relatively strong frictional force, and the paint adhering to the paint bucket is cleaned by friction.

[0038] Among them, the cleaning part 11 is composed of multiple cleaning filaments 12 and ball heads 13, and the cleaning filaments 12 and the ball heads 13 are integrally formed. The cleaning filament 12 includes a cleaning brush 1201 and an elastic filament 1202, and a through hole 12021 is opened on the elastic filament 1202. The cleaning brush 1201 has a certain elasticity, which can increase the frictional force between the cleaning filament 12 and the paint bucket. The cleaning brush 1201 is sleeved outside the elastic filament 1202, and the cleaning brush 1201 and the elastic filament 1202 are bonded by glue. The cleaning brush 1201 contacts the paint bucket, and the paint on the paint bucket is cleaned by the contact between the cleaning brush 1201 and the paint bucket.

[0039] Only processing the paint bucket through the cleaning part 11 generally has average effect. Therefore, after softening the paint bucket with water, it is more convenient to clean the paint bucket. A through hole 12021 is opened inside the elastic filament 1202, and a liquid outlet hole 1301 matching the through hole 12021 is opened on the ball head 13, and water sprays out from the liquid outlet hole 1301 through the through hole 12021. Since the ball head 13 contacts the outer wall of the paint bucket, when water sprays out from the liquid outlet hole 1301, the water can contact the inner wall or the outer wall of the paint bucket, avoiding waste of water resources. That is, through the liquid outlet hole 1301, the water can be utilized sufficiently.

[0040] See Figures 1-4 As shown, a pair of driving components 10 are fixedly connected to the upper end of the waste liquid processor main body 1. The pair of driving components 10 are fixed to the upper end of the waste liquid processor main body 1 by bolts or welding. The pair of driving components 10 are slidably connected to the connecting rods 303, and the driving components 10 can lift the cleaning column 302 up and down. In the initial state, the cleaning bucket 301 and the cleaning column 302 are separated. When the paint bucket is sleeved on the cleaning column 302, the cleaning column 302 is lifted into the cleaning bucket 301.

[0041] Preferably, the driving component 10 can be controlled by a switch to lift the cleaning column 302, or the driving component 10 can be lifted by induction to lift the cleaning column 302. For example, when a paint bucket is sleeved on the cleaning column 302, the induction component senses the paint bucket, and the induction component starts the driving component 10 to lift the cleaning column 302, so that the cleaning column 302 enters the interior of the cleaning bucket 301.

[0042] Among them, Figure 7 As shown, a plurality of liquid leakage holes 3021 are opened at the lower end of the cleaning column 302, and the paint waste liquid generated by cleaning the paint bucket falls from the liquid leakage holes 3021 through the liquid leakage holes 3021. The aperture of the liquid leakage holes 3021 is generally large, and solid paint with larger particles can pass through.

[0043] Among them, the ball head 13 is a metal sphere. During the rotation of the ball head 13, it matches with the elastic wire 1202, and the ball head 13 can knock on the paint bucket. If the paint on the paint bucket solidifies, the solidified paint on the paint bucket can be made to break away from the paint bucket faster through knocking.

[0044] Refer to Figures 1-4 As shown, a first waste liquid tank 102 matching the bucket cleaning device 3 is opened on the waste liquid processor main body 1. The first waste liquid tank 102 is opened at the bottom of the second waste liquid tank 103. The water for cleaning the paint bucket becomes paint waste liquid and flows downward due to gravity, and finally flows into the first waste liquid tank 102. Refer to Figures 3-4 As shown, a filter box 4 is clamped at the upper end of the first waste liquid tank 102. The filter box 4 can preliminarily filter the paint waste liquid entering the first waste liquid tank 102, filter the large-particle waste liquid, reduce the concentration of paint in the paint waste liquid flowing into the first waste liquid tank 102, and facilitate the treatment and secondary utilization of the paint waste liquid.

[0045] Specifically, a plurality of liquid leakage holes are opened on the bottom wall of the filter box 4, and multiple filter layers are laid on the bottom wall of the filter box 4. The multiple filter layers can be one or a combination of a filter cotton layer, a polyester fiber filter layer, a polypropylene filter layer, etc. Simply laying on the bottom wall of the filter box 4 facilitates the replacement of the filter layer on the filter box 4.

[0046] Refer to Figures 1-4 As shown, a cleaning component matching the filter box 4 is installed on one side of the waste liquid processor main body 1. The cleaning component is used to clean the impurities in the filter box 4. The cleaning component can clean the impurities in the filter box 4 by adsorption. The cleaning component includes a waste liquid collection device 5 and a first air pump 6. The first air pump 6 makes the connecting pipe 501 have an adsorption effect by pumping air, and adsorbs the paint impurities in the filter box 4.

[0047] Refer to Figure 4As shown, the waste liquid collection device 5 includes a connecting pipe 501, a first housing 502, and a waste liquid box 503. The connecting pipe 501 is used to transmit the impurities filtered by the filter box 4. The impurities transmitted by the connecting pipe 501 enter the first housing 502 and finally fall into the waste liquid box 503. The waste liquid box 503 can temporarily store the adsorbed impurities.

[0048] Since the waste liquid box 503 is slidably connected to the inside of the first housing 502, the waste liquid box 503 is convenient to be taken out from the first housing 502. A medicine supplement device for treating paint impurities can also be provided at the upper end of the first housing 502. By adding medicine to the paint in the waste liquid box 503, it is convenient for subsequent treatment of the paint impurities.

[0049] Among them, a blockage prevention box 504 matching the first air pump 6 is fixedly connected to the top wall of the first housing 502. The blockage prevention box 504 is arranged at the position where the first air pump 6 is communicated with the first housing 502, and the blockage prevention box 504 can prevent impurities from entering the first air pump 6.

[0050] Refer Figures 1-4 As shown, a first waste liquid tank 102 is also opened on the waste liquid processor main body 1, and the first waste liquid tank 102 is filled with liquid for cleaning the paint bucket. That is, the liquid in the first waste liquid tank 102 passes through the cleaning wire 12 and then sprays out from the liquid outlet hole 1301.

[0051] Specifically, a third infusion pipe 8 is connected between the bucket cleaning device 3 and the first waste liquid tank 102. A water pump 9 is fixedly connected to the third infusion pipe 8. The water pump 9 is used to provide power for the liquid in the first waste liquid tank 102, so that the liquid can move upward to the cleaning part 11.

[0052] Furthermore, the third infusion pipe 8 is respectively connected to the cleaning bucket 301 and the cleaning column 302. The third infusion pipe 8 can supply liquid to the cleaning parts 11 on both the cleaning bucket 301 and the cleaning column 302 at the same time.

[0053] Refer Figure 11 As shown, a fixing component 14 is rotatably connected to the outer wall of the cleaning column 302. A cleaning column 302 matching the cleaning part 11 is opened on the cleaning column 302. A first through hole 3022 is opened inside the cleaning column 302. A sealing cavity communicating with the first through hole 3022 is formed between the cleaning column 302 and the fixing component 14. The first through hole 3022 is communicated with the cleaning part 11. The third infusion pipe 8 is connected to the fixing component 14. The third infusion pipe 8 conveys liquid into the fixing component 14, and finally flows into the cleaning column 302, then flows through the cleaning column 302 and into the cleaning wire 12, and finally sprays onto the paint bucket from the liquid outlet hole 1301.

[0054] Similarly, a circulation component matching the third infusion tube 8 and the cleaning unit 11 is provided on the cleaning bucket 301, so that the liquid in the third infusion tube 8 can flow into the cleaning unit 11 and can be sprayed onto the paint bucket.

[0055] As shown in Figure 4 Fig. 5, a waste liquid filtering device 7 is further provided between the first waste liquid tank 102 and the second waste liquid tank 103. The waste liquid filtering device 7 is used to filter the waste liquid in the first waste liquid tank 102 to further reduce the concentration of paint in the waste liquid. The waste liquid in the first waste liquid tank 102 flows into the second waste liquid tank 103 after being filtered by the waste liquid filtering device 7. The third infusion tube 8 and the water pump 9 cooperate to enable the waste liquid in the second waste liquid tank 103 to be reused by the bucket cleaning device 3, forming a cycle, saving water resources and also saving the use cost.

[0056] Specifically, as shown in Figure 4 Fig. 6, the waste liquid filtering device 7 includes a filtering tower 701 and a second housing 702. The second housing 702 is installed inside the filtering tower 701, and the filtering tower 701 is used to protect the second housing 702. A third infusion tube is installed between the second housing 702 and the first waste liquid tank 102. The waste liquid in the first waste liquid tank 102 is transported to the second housing 702 through the third infusion tube. After the waste liquid is filtered by the second housing 702, the filtered waste liquid is further processed through the first infusion tube 7021 and the second infusion tube 7022.

[0057] Among them, the first infusion tube 7021 can transport the filtered waste liquid to the second waste liquid tank 103, and the second infusion tube 7022 transports the filtered waste liquid to the outside. The opening of the second infusion tube 7022 needs to judge the amount of waste liquid in the second waste liquid tank 103. If the amount of waste liquid in the second waste liquid tank 103 is too much, the waste liquid filtered by the second housing 702 is discharged through the second infusion tube 7022, otherwise, it is discharged into the second waste liquid tank 103 through the first infusion tube 7021.

[0058] Among them, a liquid level detection component is provided in the second waste liquid tank 103. The liquid level detection component is used to detect the amount of waste liquid in the second waste liquid tank 103, and the liquid level detection component can also be used to control the output of the first infusion tube 7021 and the second infusion tube 7022. There is also a water delivery pipeline matching the liquid level detection component. When the liquid level in the second waste liquid tank 103 is too low, water is transported to the bucket cleaning device 3 through the third infusion tube 8 through the water delivery pipeline, and the paint bucket is cleaned with water. Furthermore, it can ensure that the liquid for cleaning the paint bucket of the paint waste liquid processor will not be lacking. Embodiment 2:

[0059] Different from the first embodiment, a plurality of fixing components 14 are fixedly connected to the inner wall of the cleaning barrel 301. The plurality of fixing components 14 are used to fix the paint bucket and the cleaning barrel 301, so that when the cleaning column 302 rotates, it will not rotate the paint bucket. That is, only the inner wall of the paint bucket can be cleaned.

[0060] A plurality of adsorption components are fixedly connected to the upper part of the cleaning column 302. Similarly, the adsorption components make the paint bucket closely adhere to the cleaning column 302 by adsorption. When the cleaning barrel 301 rotates, the paint bucket will not rotate with the cleaning column 302, and only the outer wall of the paint bucket can be cleaned.

[0061] Specifically, a plurality of openings 3011 are formed in the cleaning barrel 301, and one end of the fixing component 14 is welded to the bottom wall of the opening 3011. Refer Figure 8 As shown, the fixing component 14 includes a telescopic rod 1401 and an elastic block 1402. The elastic block 1402 is installed at the end of the telescopic rod 1401 away from the opening 3011. That is, the function of the fixing component 14 is to fix the paint bucket and the cleaning barrel 301.

[0062] Through the fixing component 14 and the adsorption component, the inner wall or the outer wall of the paint bucket can be cleaned separately, which can reduce the electric energy resources consumed for cleaning the paint bucket. Of course, when only the inner wall or the outer wall of the paint bucket is cleaned separately, the corresponding cleaning part 11 will not spray liquid to help the bucket cleaning device 3 clean a certain side wall of the paint bucket. That is, when only cleaning the outer wall of the paint bucket, the cleaning part 11 located in the cleaning barrel 301 sprays liquid. When only cleaning the inner wall of the paint bucket, the cleaning part 11 located on the cleaning column 302 sprays liquid. The bucket cleaning device 3 can completely wrap the paint bucket, so that the cleaning part 11 can contact any position of the paint bucket and can clean the cleaning part 11 thoroughly.

[0063] Preferably, the cleaning wire 12 and the ball head 13 can also be provided with a plurality of anti-suction holes, which are driven by an air pump. After the paint bucket is cleaned, through the cooperation of the anti-suction holes and the air pump, the paint bucket is anti-sucked to suck the liquid in the bucket cleaning device 3, accelerating the drying of the paint bucket. At the same time, it can also reduce the paint residue on the cleaning part 11 and the cleaning wire 12, and尽可能 avoid the situation of the paint bucket being dyed due to the different colors of the paint loaded in the paint bucket.

[0064] Refer Figure 6 As shown, an ultrasonic cleaning component is fixedly connected to the inside of the cleaning column 302. The ultrasonic cleaning component is used to pre-clean the paint bucket. The ultrasonic cleaning component is used to process the solidified paint on the paint bucket, making the solidified paint on the paint bucket loose, facilitating the bucket cleaning device 3 to process the paint.

[0065] Specifically, refer Figures 4-5As shown, the ultrasonic cleaning assembly includes an ultrasonic power supply 15 and an ultrasonic transmitter 16. The ultrasonic power supply 15 supplies power to the ultrasonic transmitter 16, which is disposed inside the cleaning column 302. Generally, the distance between the ultrasonic transmitter 16 and the cleaning section 11 is 1-10 mm to avoid affecting the cleaning effect of the ultrasonic cleaning assembly due to the ultrasonic transmitter 16 being installed too deep inside the cleaning column 302.

[0066] When the paint bucket is placed on the cleaning column 302, the ultrasonic cleaning component can start working. The ultrasonic frequency emitted by the ultrasonic cleaning component can cause the cleaning wire 12 and the ball head 13 to vibrate at a certain frequency. The vibration of the cleaning wire 12 and the ball head 13 can knock on the paint bucket, which can loosen the solidified paint on the paint bucket more quickly.

[0067] The initial state of the paint waste liquid processor is that the cleaning bucket 301 and the cleaning column 302 are separated.

[0068] In use, the paint bucket is first placed on the cleaning column 302, and the cleaning column 302 is moved upwards into the cleaning bucket 301. Then, the motor 2 and the transmission block 304 are started, causing the cleaning bucket 301 and the cleaning column 302 to rotate relative to each other. The paint bucket is positioned between the cleaning bucket 301 and the cleaning column 302 and is cleaned by the cleaning section 11. At the same time, through the cooperation of the third liquid inlet pipe 8 and the water pump 9, liquid can be sprayed from the ball head 13. The liquid is sprayed onto the outer or inner wall of the paint bucket, increasing the efficiency of the bucket cleaning device 3 in cleaning the paint bucket. The waste liquid generated from cleaning the paint bucket flows downwards from the drain hole 3021. It first passes through the filter box 4, which performs preliminary filtration of the waste liquid, filtering out larger paint particles. The filtered waste liquid enters the first waste liquid tank 102, and then passes through the waste liquid filtration device 7 for further filtration. The waste liquid filtration device 7 can control whether the waste liquid is discharged into the second waste liquid tank 103 or discharged. The waste liquid entering the second waste liquid tank 103 is transported through the third infusion pipe 8 and the water pump 9, allowing the waste liquid to be reused multiple times.

[0069] When there is an excessive amount of large-particle waste liquid on filter box 4, the waste liquid collection device 5 and the first air pump 6 work together to remove the large-particle components from filter box 4, reducing the amount of large-particle coating on filter box 4 and minimizing its impact on filtration efficiency. Waste liquid box 503 collects large-particle waste for centralized processing.

[0070] Preferably, the waste liquid box 503 can be heated to prevent large particles of waste in the waste liquid box 503 from solidifying due to low temperature, thereby affecting the normal use of the waste liquid box 503 and the disposal of waste.

[0071] The foregoing description of specific exemplary embodiments of the invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the invention, as well as various different choices and variations.
