The operation is simple and easy. It only needs to insert the cleaning mechanism into the inside of the discharge pipe and inject cleaning water through the injection pipe to start the drive motor simultaneously. The operation is simple and effective. It reduces the use of a single device and improves the cleaning efficiency. The cleaned water can be discharged uniformly through the drain pipe for treatment.

[0018] 2. The setting that the diameter of the connecting block is smaller than the diameter of the discharge pipe can avoid the situation that the residual paint is pushed further into the deep of the discharge pipe and is inconvenient to clean during the insertion of the connecting block into the discharge pipe, which effectively improves the effect of subsequent cleaning. When the cleaning teeth enter, they will only separate the adhered paint into several pieces, which is convenient for the subsequent cleaning teeth to scrape and clean it, effectively improving the cleaning effect. The cleaning effect is further improved by rotating the cleaning teeth and flushing with cleaning water.

[0019] 3. By setting up auxiliary components, during the rotation of the shaft, the adjustment plate is driven to reciprocate inside the adjustment cavity through the cooperation of the sliding sleeve, the guide groove and the guide rod. When moving up, the space of the adjustment area can be reduced, and when moving down, the space of the adjustment area can be increased. The cleaning water used to clean the inner wall of the discharge pipe can be actively sucked in, thereby enhancing the fluidity of the mixture of cleaning water and paint and reducing the possibility of blockage. During the resetting process of the adjustment plate, the water inside the adjustment area can be actively pressurized, and the flow path of the cleaning water can be recoiled, achieving the effect of self-dredging, ensuring the good discharge of waste water, and the cleaning effect of the inner wall of the discharge pipe can be enhanced during the recoil process.

DETAILED DESCRIPTION

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figure 1-Figure 8 The residual paint treatment device for environmentally friendly paint production shown in the figure comprises a discharge pipe 1, a mounting plate 2 is arranged at the bottom of the discharge pipe 1, a driving motor 201 is arranged at the bottom of the mounting plate 2, and a cleaning mechanism 3 extending to the inside of the discharge pipe 1 is arranged on the surface of the mounting plate 2;

[0032] The cleaning mechanism 3 includes an injection pipe 301 disposed below the mounting plate 2, the injection pipe 301 is used to introduce cleaning water, a cleaning component 31 extending to the inside of the discharge pipe 1 is disposed above the mounting plate 2, an auxiliary component 32 is disposed inside the cleaning component 31, a drainage pipe 302 is disposed on the surface of the cleaning component 31, and a one-way valve 303 is disposed inside the drainage pipe 302;

[0033] Among them, the cleaning component 31 includes a support sleeve 3108 fixedly connected to the top of the mounting plate 2, the top of the support sleeve 3108 is fixedly connected with a connecting disk 3107, an adjusting cavity is opened inside the connecting disk 3107, the top of the connecting disk 3107 is rotatably connected with a turntable 3103, the top of the turntable 3103 is provided with a connecting block 3102 located inside the discharge pipe 1, the bottom of the connecting block 3102 is fixedly connected with a rotating shaft 3101, the lower end of the rotating shaft 3101 is fixedly connected to the output shaft of the driving motor 201, and the discharge pipe 302 is connected to the adjusting cavity.

[0034] Among them, the mounting plate 2 is adjusted in position by a driving structure with linear reciprocating motion such as a hydraulic push rod, and the hydraulic push rod and other mechanisms are relatively mature components in the existing technical applications, and will not be described in detail here;

[0035] The mounting plate 2 is moved by utilizing a driving structure such as a hydraulic push rod so that the top of the turntable 3103 contacts the lower end surface of the discharge pipe 1, and the cleaning mechanism 3 is located inside the discharge pipe 1 to facilitate cleaning of residual paint adhering to the inner wall of the discharge pipe 1. By starting the driving motor 201, the rotating shaft 3101 can be driven to rotate synchronously, and in the process, the connecting block 3102 can be driven to rotate synchronously.

[0036] like Figure 1-Figure 8 As shown, the diameter of the connecting block 3102 is smaller than the inner diameter of the discharge pipe 1, and a sealing bag 3104 is embedded and installed on the surface of the connecting block 3102. A connecting ring 3115 is fixedly connected to the bottom of the connecting block 3102, and an annularly distributed cleaning teeth 3116 are arranged on the outer side of the connecting ring 3115, and the ends of the cleaning teeth 3116 are in contact with the inner wall of the discharge pipe 1.

[0037] A flow channel 3113 is provided inside the rotating shaft 3101, and a mounting block 3112 located below the mounting plate 2 is provided on the surface of the rotating shaft 3101. A groove is provided on the inner side of the mounting block 3112. Evenly distributed liquid inlet holes 3114 are provided on the surface of the rotating shaft 3101. The flow channel 3113 is connected to the flow channel 3113 through the liquid inlet holes 3114, and the injection tube 301 is connected to the groove through the liquid inlet holes 3114.

[0038] The interior of the connecting block 3102 is provided with drainage holes 3106 which are evenly distributed and connected to the flow channel 3113. The other end of the drainage hole 3106 is opened on the outside of the connecting block 3102. The bottom of the sealing bag 3104 is connected to an evenly distributed conduit 3105. The other end of the conduit 3105 is connected to the drainage hole 3106.

[0039] A collecting channel 3110 is formed inside the cleaning tooth 3116 , an introduction groove 3117 connected to the collecting channel 3110 is formed on the surface of the cleaning tooth 3116 , and a through hole 3109 connected to the collecting channel 3110 is formed on the surface of the rotating disk 3103 .

[0040] The bottom of the rotating disk 3103 is provided with a connecting groove connected to the collecting channel 3110 , and the top of the connecting disk 3107 is provided with evenly distributed through grooves 3111 connected to the connecting groove.

[0041] The cleaning water is introduced into the interior of the groove through the injection pipe 301. The cleaning water injected under the action of the liquid inlet hole 3114 can be introduced into the drainage hole 3106 through the flow channel 3113 and discharged through the drainage hole 3106. In this process, part of the cleaning water can be introduced into the interior of the sealing bag 3104 under the action of the conduit 3105, so that the sealing bag 3104 bulges to fill the gap between the connecting block 3102 and the inner wall of the discharge pipe 1, so that a relatively sealed space is formed between the connecting block 3102, the turntable 3103 and the discharge pipe 1. The water discharged through the drainage hole 3106 can be filled between two adjacent cleaning teeth 3116 to flush the paint adhered to the inner wall of the discharge pipe 1. The cleaned water can be introduced into the interior of the collecting channel 3110 through the introduction groove 3117, and enter the interior of the regulating cavity through the guidance of the through hole 3109, the connecting groove and the through groove 3111, and finally discharged through the drainage pipe 302, which is convenient for subsequent unified cleaning, easy to operate, and no need to replace the film.

[0042] During the rotation of the connecting block 3102, the connecting ring 3115 can be driven to rotate synchronously, thereby driving the cleaning teeth 3116 to scrape and clean the inner wall of the discharge pipe 1, so that the residual paint can be better discharged together with the flushing cleaning water, thereby improving the cleaning effect and reducing the impact of residual paint on subsequent production. In addition, the paint is discharged together with the clean water through the drain pipe 302, which can directly flush away the problem of sewage that is inconvenient to collect and pollute the environment, thereby improving the environmental protection performance.

[0043] The setting that the diameter of the connecting block 3102 is smaller than the inner diameter of the discharge pipe 1 can ensure that the connecting block 3102 will not come into contact with the paint adhering to the inner wall of the discharge pipe 1 during the process of entering the discharge pipe 1, thereby avoiding the situation where the paint is pushed deep into the discharge pipe 1 and reducing the cleaning effect. When the cleaning teeth 3116 enter, they will only separate the adhering paint into several blocks, which is convenient for the subsequent cleaning teeth 3116 to scrape and clean it, effectively improving the cleaning effect.

[0044] The arrangement of the groove and the liquid inlet hole 3114 can ensure that the cleaning water can normally pass through the liquid inlet hole 3114 and flow into the interior of the flow channel 3113 during the rotation of the rotating shaft 3101 .

[0045] like Figure 1-Figure 8 As shown, the auxiliary component 32 includes a sliding sleeve 3201 slidably connected to the inner wall of the support sleeve 3108, the upper end of the sliding sleeve 3201 penetrates into the interior of the regulating cavity and is fixedly connected to an adjusting plate 3206, the adjusting plate 3206 is slidably connected to the inner wall of the regulating cavity, and a pressure regulating area is formed between the top of the adjusting plate 3206 and the inner wall of the regulating cavity.

[0046] A guide groove 3202 is provided on the surface of the sliding sleeve 3201 , and the guide groove 3202 is formed by a plurality of “V”-shaped grooves connected end to end. A guide rod 3203 is fixedly connected to the inner wall of the support sleeve 3108 , and the other end of the guide rod 3203 is slidably connected to the inner wall of the guide groove 3202 .

[0047] A fixing ring 3204 is fixedly connected to the inner wall of the support sleeve 3108 , and a spring 3205 is provided between the top of the fixing ring 3204 and the sliding sleeve 3201 .

[0048] During the rotation of the rotating shaft 3101, the sliding sleeve 3201 can be driven to rotate synchronously. Since the guide rod 3203 is fixed to the inner wall of the supporting sleeve 3108, the position of the guide rod 3203 will not change. Therefore, during the rotation of the sliding sleeve 3201, the guide rod 3203 can push the inner wall of the guide groove 3202 to drive the sliding sleeve 3201 to move up and down, so that the adjusting plate 3206 can move back and forth inside the adjusting cavity. When moving up, the space of the adjusting area can be reduced, and when moving down, the space of the adjusting area can be increased.

[0049] After the cleaned water is introduced into the interior of the regulating area, it can gradually overcome the pressure of the one-way valve 303 as the amount of water increases and be discharged through the drain pipe 302. In the process of the downward movement of the regulating plate 3206, the internal space of the regulating area is increased, so that the pressure inside the regulating area is lower than the internal pressure of the discharge pipe 1. At this time, the cleaning water used to clean the inner wall of the discharge pipe 1 can be actively sucked in, which enhances the fluidity of the mixture of cleaning water and paint and reduces the possibility of blockage. In the process of resetting the regulating plate 3206, the water inside the regulating area can be actively pressurized to make it discharge faster through the drain pipe 302, and part of the water can be re-injected into the interior of the discharge pipe 1. In this process, the flow path of the cleaning water can be backflushed, achieving a self-dredging effect, ensuring a good discharge of waste water, and the cleaning effect of the inner wall of the discharge pipe 1 can be enhanced during the backflushing process.

[0050] Working principle: The mounting plate 2 is moved by a driving structure such as a hydraulic push rod so that the top of the rotating disk 3103 contacts the lower end surface of the discharge pipe 1, so that the cleaning mechanism 3 is located inside the discharge pipe 1 to facilitate cleaning of the residual paint adhering to the inner wall of the discharge pipe 1. By starting the driving motor 201, the rotating shaft 3101 can be driven to rotate synchronously, and the connecting block 3102 is driven to rotate synchronously in the process. At the same time, the cleaning water is injected into the flow channel 3113 through the injection pipe 301. In the process, the sealing bag 3104 swells and fills the connecting block 3 The gap between the connecting block 3102 and the inner wall of the discharge pipe 1 forms a relatively sealed space between the connecting block 3102, the rotating disk 3103 and the discharge pipe 1. The water discharged through the drainage hole 3106 can fill between two adjacent cleaning teeth 3116 to flush the paint adhered to the inner wall of the discharge pipe 1. The cleaned water can be introduced into the interior of the collecting channel 3110 through the introduction groove 3117, and enter the interior of the regulating cavity through the through hole 3109, the connecting groove and the through groove 3111, and finally discharged through the drainage pipe 302. , which is convenient for subsequent unified cleaning, easy to operate, and no need to replace the film. At the same time, the connecting ring 3115 rotates synchronously, thereby driving the cleaning teeth 3116 to scrape and clean the inner wall of the discharge pipe 1, so that the residual paint can be better discharged together with the cleaning water for flushing, improving the cleaning effect and reducing the impact of residual paint on subsequent production. The paint is discharged together with the cleaning water through the drain pipe 302, and the sewage caused by direct flushing is not convenient to collect and pollute the environment, thereby improving the environmental protection performance. By setting the auxiliary component 32, the cleaning water inside the discharge pipe 1 can be actively absorbed, the fluidity of the mixture of cleaning water and paint is enhanced, and the possibility of blockage is reduced. During the resetting process of the adjustment plate 3206, the water inside the adjustment area can be actively pressurized to make it faster through the drain pipe 302. Discharge, and part of the water can be re-injected into the interior of the discharge pipe 1. In this process, the backwashing of the flow path of the cleaning water can be achieved, and the effect of self-dredging is achieved, ensuring the good discharge of wastewater, and the cleaning effect of the inner wall of the discharge pipe 1 can be enhanced during the backwashing process.
