Description

Technical Field

[0001] The present application relates to the field of water-based paint processing technology, and in particular to a grinding device for water-based paint production. Background Art

[0002] In the production process of water-based paint, the water-based paint produced at the production site needs to be ground to make the paint particles fine and uniform. Among them, the fineness of water-based paint directly affects the gloss, penetration performance and storage stability of water-based paint. The smaller the particles of water-based paint, the better the dispersibility in the dispersion medium, the higher the flatness of the formed paint film, and the better the appearance visual effect.

[0003] In the prior art, a common water-based paint grinding device mainly includes a frame, a hopper is installed on the frame, a servo motor is installed on the sealing plate at the opening of the hopper, a grinding tube is formed at the bottom of the hopper, grinding beads, a swivel, etc. are arranged in the grinding tube, a center rod is tightly sleeved on the driving shaft end of the servo motor, a rotating rod is fixedly connected to the bottom of the center rod, the rotating rod is buried in the grinding beads, the bottom of the rotating rod is fixedly connected to the swivel, a feed port is opened on the sealing cover, and the operator can add semi-finished water-based paint into the hopper through the feed port, and then the center rod, the rotating rod and the swivel can be driven to rotate by the servo motor, and the water-based paint can be refined after passing through the grinding beads and the swivel in turn.

[0004] However, after the water-based paint is ground, the operator needs to inject a large amount of clean water into the hopper to clean the inside of the hopper to prevent the water-based paint remaining on the inner wall of the hopper, grinding beads and rotor from affecting the subsequent raw material grinding processing. The manual cleaning of the water-based paint by the operator is relatively cumbersome, and the operator is required to detect the discharged wastewater in real time to determine whether the hopper has been cleaned. The cleaning process is relatively cumbersome and inefficient, and there is room for improvement. Utility Model Content

[0005] In order to improve the convenience for operators to clean the hopper of the grinding equipment, the present application provides a grinding equipment for water-based paint production.

[0006] The present application provides a grinding device for water-based paint production using the following technical solution:

[0007] A grinding device for water-based paint production comprises a frame, a hopper and a raw material pipeline are fixedly mounted on the frame, a liquid outlet end of the raw material pipeline is fixedly mounted on a cover, and a liquid inlet end of the raw material pipeline is connected to a raw material tank storing water-based paint raw materials;

[0008] The bottom of the grinding tube of the hopper is connected to a discharge pipe; and:

[0009] A control panel, fixedly mounted on the frame, for inputting a grinding start signal and a cleaning start signal;

[0010] A feed pump, installed on the raw material pipeline, connected to the signal output terminal of the control panel, for receiving the grinding start signal and adding water-based paint raw materials into the hopper;

[0011] A discharge valve, installed on the discharge pipe, with a signal input end connected to a signal output end of the control panel, for receiving the grinding start signal and connecting to the discharge pipe;

[0012] A servo motor is fixedly mounted on the cover, and its signal input end is connected to the signal output end of the control panel, and is used to receive the grinding start signal and drive the center rod, the rotating rod and the rotating body to rotate at a uniform speed;

[0013] A cleaning mechanism, whose signal input end is signal-connected to the signal output end of the control panel, and is used to receive the cleaning start signal and inject clean water into the hopper;

[0014] The wastewater detection module is fixedly mounted on the inner wall of the grinding tube and is located below the rotating body. It is used to detect the turbidity of the clean water flowing out of the grinding tube and output a control signal when the turbidity of the clean water is less than a set value.

[0015] The signal input ends of the servo motor and the cleaning mechanism are signal-connected to the signal output end of the wastewater detection module, and the servo motor and the cleaning mechanism receive the control signal and stop running.

[0016] By adopting the above technical scheme, during the actual production and processing process, the operator can connect the raw material pipeline with the raw material tank, and place the tank body for collecting the finished water-based paint just below the discharge pipe, and then input the grinding start signal through the control panel. After receiving the grinding start signal, the servo motor drives the center rod, the rotating rod and the rotating body to rotate at a uniform speed. The water-based paint is ground and refined when passing through the grinding beads and the rotating body in the grinding tube, and finally flows out through the discharge pipe at the lower end of the grinding tube, thereby realizing the technical effect of automatically grinding the water-based paint raw materials; when the grinding is completed, the operator can input the cleaning start signal through the control panel, and the cleaning mechanism injects clean water into the hopper after receiving the cleaning start signal. During the cleaning process, the wastewater detection module detects the turbidity of the wastewater flowing out through the grinding tube. When the turbidity of the wastewater is less than the set value, it can be determined that the grinding beads and the rotating body in the wastewater hopper have been cleaned, and the servo motor and the cleaning mechanism can be controlled to stop running, thereby realizing the technical effects of automatically cleaning the inside of the hopper, automatically detecting the cleanliness of the hopper, and automatically shutting down the cleaning, thereby ensuring the cleaning effect of the cleaning hopper while saving water.

[0017] Preferably, a clean water pipe and a drainage pipe are fixedly installed on the frame, the liquid inlet end of the clean water pipe is connected to the indoor water supply system, and the liquid inlet end of the clean water pipe is fixed on the cover and extends into the hopper;

[0018] The liquid inlet end of the drainage pipe is communicated with the discharge pipe, and the liquid inlet end of the discharge pipe is located between the grinding pipe and the discharge valve;

[0019] The cleaning mechanism comprises:

[0020] A water inlet valve, installed on the clean water pipeline, with a signal input end connected to a signal output end of the control panel, for receiving the cleaning start signal to inject clean water into the hopper;

[0021] A drain valve, installed on the drain pipe, with a signal input end connected to a signal output end of the control panel, for receiving the cleaning start signal and connecting to the drain pipe;

[0022] The signal input end of the discharge valve is signal-connected to the signal output end of the control panel, and the discharge valve receives the cleaning start signal and shuts off the discharge pipeline.

[0023] By adopting the above technical solution, when the operator inputs the cleaning start signal through the control panel, the water inlet valve is connected to the water inlet pipe to inject clean water into the hopper. During this process, the servo motor continues to rotate to drive the grinding beads and the rotor to rotate. The clean water can take away the residual water-based paint on the grinding beads and the rotor during the process of passing through the grinding beads and the rotor, and discharge it through the drainage pipe, thereby achieving the technical effect of automatically cleaning the inside of the hopper.

[0024] Preferably, the wastewater detection module comprises:

[0025] A turbidity sensor is installed in the grinding tube and is connected to the signal output terminal of the control panel, and is used to receive the cleaning start signal and detect the turbidity of the wastewater discharged through the grinding tube and output a wastewater turbidity signal;

[0026] The single chip microcomputer is connected to the signal output terminal of the turbidity sensor, and is used for receiving and comparing the wastewater turbidity signal, and outputting the control signal when the wastewater turbidity is less than a set value.

[0027] By adopting the above technical solution, as the cleaning time increases, the amount of water-based paint remaining on the grinding beads and the rotor decreases, and the turbidity of the wastewater discharged through the grinding tube decreases. When the turbidity of the wastewater drops to less than the set value, it can be determined that the cleanliness inside the hopper has reached the required level. At this time, the single-chip microcomputer can control the servo motor to stop running, and at the same time turn off the water inlet valve and the drain valve, thereby achieving the technical effect of automatically detecting the cleanliness and automatically closing the cleaning mechanism.

[0028] Preferably, the center rod is fixedly connected to two connecting rods, the ends of the two connecting rods are respectively fixedly connected to flexible scrapers, and the two flexible scrapers are respectively offset to correspond to the upper and lower parts of the inner wall of the hopper.

[0029] By adopting the above technical solution, when the servo motor drives the center rod, the rotating rod and the rotating body to rotate at a constant speed, the two flexible scrapers can be driven to rotate synchronously. During the grinding process, the flexible scraper passes through the inner wall of the hopper, which can reduce the occurrence of water-based paint remaining on the inner wall of the hopper; during the cleaning process, the flexible scraper passes through the inner wall of the hopper, which can scrape off the water-based paint remaining on the inner wall of the hopper, thereby improving the cleaning effect.

[0030] In summary, the present invention provides a grinding device for producing water-based paint, which has at least one of the following beneficial technical effects:

[0031] 1. The operator can input the cleaning start signal through the control panel. After receiving the cleaning start signal, the cleaning mechanism injects clean water into the hopper. During the cleaning process, the wastewater detection module detects the turbidity of the wastewater flowing out through the grinding pipe. When the wastewater turbidity is less than the set value, it can be determined that the grinding beads and the rotor in the wastewater hopper have been cleaned, and the servo motor and the cleaning mechanism are controlled to stop running, which can achieve the technical effects of automatically cleaning the inside of the hopper, automatically detecting the cleanliness of the hopper, and automatically shutting down the cleaning, which can ensure the cleaning effect of the cleaning hopper while saving water;

[0032] 2. During the cleaning process, the flexible scraper passes through the inner wall of the hopper and can scrape off the water-based paint remaining on the inner wall of the hopper to improve the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is combined with Figure 1-2 This application is described in further detail.

[0037] Example

[0038] The present application embodiment discloses a grinding device for producing water-based paint. Figure 1 and Figure 2, which mainly includes a frame 1. A hopper 2 and a raw material pipeline 22 are fixedly installed on the frame 1, the liquid outlet end of the raw material pipeline 22 is fixedly installed on the cover 21, and the liquid inlet end of the raw material pipeline 22 is connected to a raw material tank storing water-based paint raw materials; the bottom of the grinding tube 28 of the hopper 2 is connected to a discharge pipeline 23.

[0039] And: a control panel 4, fixedly mounted on the frame 1, for inputting a grinding start signal and a cleaning start signal; a feed pump 221, mounted on the raw material pipeline 22, connected to the signal output end of the control panel 4, for receiving the grinding start signal and adding water-based paint raw materials into the hopper 2; a discharge valve 231, mounted on the discharge pipeline 23, with the signal input end connected to the signal output end of the control panel 4, for receiving the grinding start signal and connecting the discharge pipeline 23; a servo motor 24, fixedly mounted on the cover 21, with the signal input end connected to the signal output end of the control panel 4, for receiving the grinding start signal and driving the center rod 25, the rotating rod 26 and the rotating body 27 to rotate at a uniform speed; a cleaning mechanism 5, with the signal input end connected to the signal output end of the control panel 4, for receiving the cleaning start signal and injecting clean water into the hopper 2; a wastewater detection module, fixedly mounted on the inner wall of the grinding tube 28, located below the rotating body 27, for detecting the turbidity of the clean water flowing out through the grinding tube 28, and outputting a control signal when the turbidity of the clean water is less than a set value.

[0040] The signal input ends of the servo motor 24 and the cleaning mechanism 5 are connected to the signal output ends of the wastewater detection module. The servo motor 24 and the cleaning mechanism 5 receive the control signal and stop running.

[0041] During the actual production and processing process, the operator can connect the raw material pipeline 22 to the raw material tank, and place the tank body for collecting the finished water-based paint directly under the discharge pipe 23, and then input the grinding start signal through the control panel 4. After receiving the grinding start signal, the servo motor 24 drives the center rod 25, the rotating rod 26 and the rotating body 27 to rotate at a uniform speed. The water-based paint is ground and refined when passing through the grinding beads 29 and the rotating body 27 in the grinding tube 28, and finally flows out through the discharge pipe 23 at the lower end of the grinding tube 28, thereby achieving the technical effect of automatically grinding the water-based paint raw materials.

[0042] When the grinding is completed, the operator can input a cleaning start signal through the control panel 4. After receiving the cleaning start signal, the cleaning mechanism 5 injects clean water into the hopper 2. During the cleaning process, the wastewater detection module detects the turbidity of the wastewater flowing out through the grinding tube 28. When the turbidity of the wastewater is less than the set value, it can be determined that the grinding beads 29 and the rotor 27 in the wastewater hopper 2 are cleaned, and the servo motor 24 and the cleaning mechanism 5 are controlled to stop running, which can achieve the technical effects of automatically cleaning the inside of the hopper 2, automatically detecting the cleanliness of the hopper 2, and automatically shutting down the cleaning, which can ensure the cleaning effect of the hopper 2 while saving water.

[0043] In the embodiment of the present application, a clean water pipe 51 and a drainage pipe 52 are fixedly installed on the frame 1, the liquid inlet end of the clean water pipe 51 is connected to the indoor water supply system, and the liquid inlet end of the clean water pipe 51 is fixed on the cover 21 and extends into the hopper 2; the liquid inlet end of the drainage pipe 52 is connected to the discharge pipe 23, and the liquid inlet end of the discharge pipe 23 is located between the grinding tube 28 and the discharge valve 231.

[0044] The cleaning mechanism 5 includes: an inlet valve 511, which is installed on the clean water pipe 51, and its signal input end is signal-connected with the signal output end of the control panel 4, and is used to receive a cleaning start signal to inject clean water into the hopper 2; a drain valve 521, which is installed on the drain pipe 52, and its signal input end is signal-connected with the signal output end of the control panel 4, and is used to receive a cleaning start signal and connect to the drain pipe 52; the signal input end of the discharge valve 231 is signal-connected with the signal output end of the control panel 4, and the discharge valve 231 receives the cleaning start signal and shuts off the discharge pipe 23.

[0045] When the operator inputs a cleaning start signal through the control panel 4, the water inlet valve 511 is connected to the water inlet pipe to inject clean water into the hopper 2. During this process, the servo motor 24 continues to rotate to drive the grinding beads 29 and the rotator 27 to rotate. The clean water can take away the residual water-based paint on the grinding beads 29 and the rotator 27 when passing through the grinding beads 29 and the rotator 27, and discharge it through the drainage pipe 52, thereby achieving the technical effect of automatically cleaning the inside of the hopper 2.

[0046] Reference Figure 1 and Figure 2 The wastewater detection module includes: a turbidity sensor 6, which is installed in the grinding tube 28 and is signal-connected to the signal output end of the control panel 4, for receiving a cleaning start signal and detecting the turbidity of the wastewater discharged through the grinding tube 28 and outputting a wastewater turbidity signal; a single-chip microcomputer, which is signal-connected to the signal output end of the turbidity sensor 6, for receiving and comparing the wastewater turbidity signal and outputting a control signal when the wastewater turbidity is less than a set value.

[0047] As the cleaning time increases, the amount of water-based paint remaining on the grinding beads 29 and the rotor 27 decreases, and the turbidity of the wastewater discharged through the grinding tube 28 decreases. When the turbidity of the wastewater drops to less than the set value, it can be determined that the cleanliness inside the hopper 2 has reached the required level. At this time, the single-chip microcomputer can control the servo motor 24 to stop running, and at the same time turn off the water inlet valve 511 and the drain valve 521, thereby achieving the technical effect of automatically detecting the cleanliness and automatically closing the cleaning mechanism 5.

[0048] Reference Figure 1 The center rod 25 is fixedly connected to two connecting rods 251 , and the ends of the two connecting rods 251 are respectively fixedly connected to flexible scrapers 252 , and the two flexible scrapers 252 are respectively offset to correspond to the upper and lower parts of the inner wall of the hopper 2 .

[0049] When the servo motor 24 drives the center rod 25, the rotating rod 26 and the rotating body 27 to rotate at a constant speed, the two flexible scrapers 252 can be driven to rotate synchronously. During the grinding process, the flexible scraper 252 passes through the inner wall of the hopper 2, which can reduce the occurrence of water-based paint remaining on the inner wall of the hopper 2; during the cleaning process, the flexible scraper 252 passes through the inner wall of the hopper 2, which can scrape off the water-based paint remaining on the inner wall of the hopper 2, thereby improving the cleaning effect.

[0050] It should be noted that, in the embodiment of the present application, the pipe body parts of the raw material pipe 22, the clean water pipe 51 and the drainage pipe 52 are all fixed to the frame 1 by fasteners and the like.

[0051] The implementation principle of a grinding device for producing water-based paint in the embodiment of the present application is as follows: during the actual production and processing process, the operator can connect the raw material pipeline 22 with the raw material tank, and place the tank body for collecting the finished water-based paint just below the discharge pipe 23, and then input a grinding start signal through the control panel 4. After receiving the grinding start signal, the servo motor 24 drives the center rod 25, the rotating rod 26 and the rotating body 27 to rotate at a uniform speed. The water-based paint is ground and refined when passing through the grinding beads 29 and the rotating body 27 in the grinding tube 28, and finally flows out through the discharge pipe 23 at the lower end of the grinding tube 28, thereby realizing automatic grinding of the water-based paint raw materials. Technical effect: When the grinding is completed, the operator can input a cleaning start signal through the control panel 4. After receiving the cleaning start signal, the cleaning mechanism 5 injects clean water into the hopper 2. During the cleaning process, the wastewater detection module detects the turbidity of the wastewater flowing out through the grinding tube 28. When the turbidity of the wastewater is less than the set value, it can be determined that the grinding beads 29 and the rotor 27 in the wastewater hopper 2 are cleaned, and the servo motor 24 and the cleaning mechanism 5 are controlled to stop running, which can achieve the technical effects of automatically cleaning the inside of the hopper 2, automatically detecting the cleanliness of the hopper 2, and automatically shutting down the cleaning, which can ensure the cleaning effect of the hopper 2 while saving water.
