Description

Technical Field

[0001] This utility model belongs to the field of electrophoretic paint processing technology, and more specifically, it relates to a disperser for electrophoretic paint processing with high dispersion efficiency. Background Technology

[0002] A disperser is a stirring device used to disperse different substances. When processing electrophoretic paint, a disperser is needed to disperse the auxiliary materials to make the internal material of the electrophoretic paint uniform and to better facilitate electrophoresis. The additives are mainly defoamers, neutralizers and resins.

[0003] Based on the above, the currently used dispersers adopt an open structure for mixing, dispersing and discharging, which makes it inconvenient to discharge from the bottom and remove paint from dead corners. They lack a quick discharge effect and do not automatically clean the inner wall during the discharge process, making it inconvenient to automatically adjust the proportion for addition. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-efficiency disperser for electrophoretic paint processing, which solves the problems mentioned in the background art that the existing dispersers use an open structure for stirring, dispersing and discharging, which is inconvenient for discharging from the bottom and removing paint from dead corners, lacks a fast discharge effect, and does not automatically clean the inner wall during the discharge process, making it inconvenient to automatically adjust the proportion for adding paint.

[0005] The purpose and effect of this utility model, a highly efficient dispersing machine for electrophoretic paint processing, are achieved by the following specific technical means:

[0006] A high-efficiency disperser for electrophoretic coating processing includes a disperser chamber with an input port connected to the top front side of the disperser chamber. The top of the input port has a bucket-shaped structure. The disperser chamber has a conical bucket-shaped structure at its bottom for easy guidance, and a cylindrical structure is integrally connected to the bottom of the disperser chamber. A downwardly inclined discharge port is integrally provided on the periphery of this cylindrical structure. A drive motor is fixedly installed at the top of the disperser chamber. An agitator is fixedly installed at the shaft end of the drive motor, and the agitator is rotatably mounted inside the disperser chamber with bearings. Three rows of inclined agitator blades are integrally provided outside the agitator. A valve-controlled electric cylinder is fixedly installed at the bottom of the disperser chamber, and a sealing plug is fixedly installed at the telescopic end of the valve-controlled electric cylinder. Three sets of L-shaped channels for material input are fixedly installed at the top of the disperser chamber. A conveying piston is connected to the top of each L-shaped channel. An L-shaped frame is fixedly installed outside the L-shaped channels, and a control electric cylinder for controlling the conveying volume and speed is fixedly installed at the top of the L-shaped frame. The telescopic end of the control electric cylinder is fixedly connected to the telescopic end of the conveying piston.

[0007] Furthermore, a toggle is provided below the stirrer, and a hexagonal shaft is integrally provided on the top of the toggle, which slides in the middle of the bottom of the stirrer; two sets of levers are integrally provided on both sides of the toggle, and a rubber sheet is provided below each lever.

[0008] Furthermore, a protrusion is integrally provided in the middle of the top of the sealing plug, and the bottom of the actuator is rotatably mounted on the outside of the protrusion on the top of the sealing plug in conjunction with an airtight bearing.

[0009] Furthermore, two sets of one-way valves are connected to the outside of each L-shaped channel, and a nozzle is connected to the lower one-way valve by a pipe. The nozzle is fixed to the top of the dispersing chamber.

[0010] Furthermore, the outer end of the aforementioned one-way valve is provided with a pipe connected to a separator, and one end of the separator is connected to an input pipe; a collection bottle is fixedly installed at the bottom of the separator; a filter screen is fixedly installed inside the separator, and the filter screen separates the output port of the separator from the input pipe and the collection bottle.

[0011] Furthermore, a scraper is rotatably connected to the upper exterior of the agitator via a ratchet structure, and the side of the scraper is attached to the inner wall of the dispersing chamber.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The agitator can improve dispersion and discharge efficiency. During the rotation of the agitator, the inclined agitator blades on the side of the agitator generate an upward pushing force to tumble the paint. At the same time, the agitator drives the hexagonal shaft and the agitator to rotate synchronously, tumbling the bottom. Conversely, the shrink valve control cylinder can expose the discharge port to discharge the material. The agitator provides a downward force to assist in the discharge, and the synchronous rotation of the agitator uses centrifugal force to expel the material outward, avoiding dead corners where paint accumulates.

[0014] The scraper is equipped with a cleaning function. The scraper uses a ratchet structure and does not rotate with the agitator during the dispersion process. When the agitator reverses, the ratchet structure drives the scraper to rotate, scraping the inner wall of the dispersion chamber to prevent paint from adhering to the inner wall of the dispersion chamber.

[0015] The L-shaped channel provides a quantitative addition function. By controlling the extension and retraction of the electric cylinder, the volume change of the conveying piston can be controlled. Using the volume change of the conveying piston, auxiliary materials are drawn from the input pipe. The auxiliary materials enter the separator and are filtered by the filter screen. After passing through the upper one-way valve, they enter the conveying piston for replenishment. Then, the constriction of the conveying piston transports the internal material through the lower one-way valve to the nozzle and sprays it into the disperser chamber, thus realizing automatic quantitative addition.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0025] Example 1:

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a high-efficiency disperser for electrophoretic coating processing, including a disperser chamber 1. An inlet 101 is connected to the top front of the disperser chamber 1, and the top of the inlet 101 has a bucket-shaped structure. The bottom of the disperser chamber 1 has a conical bucket-shaped structure for easy guidance, and a cylindrical structure is integrally connected to the bottom of the disperser chamber 1. A downwardly inclined outlet 102 is integrally provided on the periphery of this cylindrical structure. A drive motor 2 is fixedly installed on the top of the disperser chamber 1. An agitator 3 is fixedly installed on the shaft end of the drive motor 2, and the agitator 3 is rotatably mounted on the disperser with bearings. Inside the disperser 1; three rows of inclined stirring blades are integrally installed on the outside of the agitator 3; a valve-controlled electric cylinder 4 is fixedly installed at the bottom of the disperser 1, and a sealing plug 401 is fixedly installed at the telescopic end of the valve-controlled electric cylinder 4; three sets of L-shaped channels 5 for material input are fixedly installed at the top of the disperser 1; a conveying piston 6 is connected to the top of the L-shaped channel 5; an L-shaped frame 7 is fixedly installed outside the L-shaped channel 5, and a control electric cylinder 701 for controlling the conveying amount and conveying speed is fixedly installed at the top of the L-shaped frame 7, and the telescopic end of the control electric cylinder 701 is fixedly connected to the telescopic end of the conveying piston 6.

[0028] The stirrer 3 has a toggle 301 at the bottom, and a hexagonal shaft 302 is integrally mounted on the top of the toggle 301. The hexagonal shaft 302 slides in the middle of the bottom of the stirrer 3. Two sets of levers are integrally mounted on both sides of the toggle 301, and a rubber sheet is mounted below each lever.

[0029] The sealing plug 401 has an integrally formed protrusion at the top center, and the actuator 301 is rotatably mounted on the outside of the protrusion at the top of the sealing plug 401 in conjunction with an airtight bearing.

[0030] Two sets of one-way valves 501 are connected to each of the L-shaped channels 5. A nozzle 502 is connected to the one-way valve 501 at the bottom through a pipe. The nozzle 502 is fixed to the top of the dispersing chamber 1.

[0031] The upper one-way valve 501 has a pipe connected to a separator 8 at its outer end, and an input pipe 801 is connected to one end of the separator 8. A collection bottle 802 is fixedly installed at the bottom of the separator 8. A filter screen 803 is fixedly installed inside the separator 8, and the filter screen 803 separates the output port of the separator 8 from the input pipe 801 and the collection bottle 802.

[0032] Among them, the upper exterior of the agitator 3 is connected to the scraper 9 in a ratchet structure, and the side of the scraper 9 is attached to the inner wall of the disperser chamber 1.

[0033] like Figure 1-6As shown, the raw paint is input from the input port 101, and then the drive motor 2 is started to drive the agitator 3 to rotate. The agitator 3 is used to stir the paint. During the rotation of the agitator 3, the inclined stirring blades on the side of the agitator 3 generate an upward pushing force to stir the paint. At the same time, the agitator 3 drives the hexagonal shaft 302 and the toggle 301 to rotate synchronously to stir the bottom.

[0034] The three sets of input pipes 801 are connected to different auxiliary material sources to provide defoamer, neutralizer and resin;

[0035] The control cylinder 701 is started quantitatively by the program. According to the ratio, the extension and retraction time of each group of control cylinders 701 is the same but the stroke is different. Then, the extension and retraction of the delivery piston 6 is controlled by the control cylinder 701.

[0036] When the conveying piston 6 retracts, the internal material is conveyed through the lower one-way valve 501 to the nozzle 502 and sprayed into the disperser chamber 1.

[0037] When the conveying piston 6 extends, the input pipe 801 draws in the auxiliary material. The auxiliary material enters the separator 8 and is filtered by the filter screen 803. Then it passes through the upper one-way valve 501 and enters the conveying piston 6 for replenishment.

[0038] After dispersion is completed, reverse drive motor 2 and agitator 3 are reversed, control valve electric cylinder 4 is contracted, sealing plug 401 is lowered, and discharge port 102 is exposed for material discharge.

[0039] At this time, the stirring blades outside the agitator 3 provide a downward force to assist in the discharge of materials, and the actuator 301 rotates synchronously to discharge the materials outward, avoiding the accumulation of paint in dead corners;

[0040] The agitator 3 also drives the scraper 9 to rotate via a ratchet structure, scraping the inner wall of the dispersing chamber 1 to prevent paint from adhering to the inner wall of the dispersing chamber 1.

[0041] Example 2:

[0042] Based on Example 1, the number of L-shaped channels 5 depends on the amount of excipients. When the types of excipients are increased or decreased according to the technological upgrade, the number of L-shaped channels 5 can be increased or decreased accordingly to ensure that different excipients are added in a quantitative manner.

[0043] The specific usage and function of this embodiment are as follows:

[0044] In this utility model, when in use, the raw paint is input from the input port 101, and then the drive motor 2 is started to drive the stirrer 3 to rotate. The stirrer 3 is used to stir the paint. During the rotation of the stirrer 3, the inclined stirring blades on the side of the stirrer 3 generate an upward pushing force to stir the paint. At the same time, the stirrer 3 drives the hexagonal shaft 302 and the toggle 301 to rotate synchronously to stir the bottom, thus achieving efficient dispersion.

[0045] The three sets of input pipes 801 are connected to different auxiliary material sources to provide defoamer, neutralizer and resin;

[0046] The control cylinder 701 is started quantitatively by the program. According to the ratio, the extension and retraction time of each group of control cylinders 701 is the same but the stroke is different. When the control cylinder 701 extends, it squeezes the conveying piston 6. The conveying piston 6 retracts and conveys the internal material through the lower one-way valve 501 to the nozzle 502 and sprays it into the disperser chamber 1. When the conveying piston 6 extends, the input pipe 801 draws in the auxiliary material. The auxiliary material enters the separator 8 and is filtered by the filter interception screen 803. Then it passes through the upper one-way valve 501 and enters the conveying piston 6 for replenishment.

[0047] After dispersion is completed, reverse drive motor 2 and agitator 3, shrink valve control cylinder 4 lowers sealing plug 401, exposes discharge port 102 for material discharge, agitator blades outside agitator 3 provide downward force to assist material discharge, and actuator 301 rotates synchronously to discharge material outward, avoiding dead corner accumulation of paint.

[0048] When the agitator 3 reverses, the ratchet structure drives the scraper 9 to rotate, scraping the inner wall of the dispersing chamber 1 to prevent paint from adhering to the inner wall of the dispersing chamber 1.
