Description

A coating reaction vessel Technical Field

[0001] This utility model relates to coating processing equipment, and more particularly to a coating reaction vessel. Background Technology

[0002] During storage, paint composition can become uneven due to sedimentation, pigment and solvent stratification. Therefore, before use, paint needs to be stirred to ensure uniformity and stability. Workers typically use handheld mixers to stir the paint in the air, which introduces air into the paint, creating many small air bubbles. When paint containing these bubbles is applied to a workpiece / wall surface, the trapped bubbles cannot release quickly enough, causing small bubbles to form on the coating surface after drying. Alternatively, as the bubbles burst during drying, they can create pinhole-like pits on the coating surface, affecting its smoothness and appearance. Summary of the Invention

[0003] Therefore, in view of the above problems, this utility model proposes a coating reaction vessel, which can greatly reduce the formation of air bubbles in the coating during the mixing of coatings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A coating reaction vessel includes a reaction vessel body, an industrial controller, and a touch control screen. The reaction vessel body has a cavity for holding coatings. A cover is provided at the opening of the cavity. An electric stirrer for stirring the coatings in the cavity is provided on the cover. The electric stirrer and the touch control screen are electrically connected to the industrial controller.

[0006] A sealing gasket is fitted on the side of the cover, the sealing gasket is in contact with the inner wall of the cavity, and the sealing gasket on the side of the cover can slide up and down along the inner wall of the cavity.

[0007] The cover also has a connecting hole;

[0008] It also includes a three-way connecting pipe, a non-contact level sensor, hoses, and a vacuum pump;

[0009] The three-way connecting pipe includes a first pipe opening, a second pipe opening, and a third pipe opening arranged vertically from bottom to top. The first pipe opening is sealed to a connecting hole, the non-contact liquid level sensor is sealed to the second pipe opening, and the vacuum pump is sealed to the third pipe opening via a flexible hose.

[0010] The non-contact liquid level sensor and vacuum pump are electrically connected to the industrial controller.

[0011] Furthermore, a viewing window is provided on the tee connecting pipe, and a transparent sheet is sealed on the viewing window;

[0012] The bottom of the view window is located above the first pipe opening, and the top of the view window is located below the third pipe opening.

[0013] Furthermore, it also includes an indicator light; the indicator light is electrically connected to the industrial controller.

[0014] Furthermore, it also includes a loudspeaker; the loudspeaker is electrically connected to the industrial controller.

[0015] Furthermore, the inner wall of the cavity, the lower surface of the cover, and the inner wall of the tee connecting pipe are all coated with an anti-stick coating.

[0016] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0017] When using this coating reactor, after the coating is added to the cavity, the industrial controller operated via the touch control screen starts the vacuum pump, extracting air from the cavity. This causes the lid to move downwards under atmospheric pressure until a small amount of coating overflows into the T-connector pipe. When the non-contact liquid level sensor installed on the T-connector pipe detects that the liquid level has risen to a certain position (below the position of the third pipe opening), the vacuum pump stops evacuating air. Then, the electric stirrer can be controlled to stir the coating in the cavity evenly. After stirring is complete, the industrial controller controls the vacuum pump to introduce air into the cavity through the T-connector pipe until the air pressure in the cavity is equal to the atmospheric pressure, ensuring that the coating in the cavity can be discharged normally from the reactor body (through the discharge port of the reactor body).

[0018] Since most of the air in the container is expelled during mixing (except for a small amount of air in the T-connector pipe), it can greatly reduce the amount of air mixed into the paint and the formation of bubbles. Attached Figure Description

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] Referring to Figures 1-4, this embodiment provides a coating reaction vessel, including a reaction vessel body 1, a cover 2, an electric stirrer 3, a three-way connecting pipe 4, a non-contact liquid level sensor 5, a hose 6, a vacuum pump 7, an industrial controller 8, a touch control screen 9, an indicator light 10, and a speaker 11.

[0025] The reactor body 1 has a cavity 100 for holding the coating. The cover 2 is located at the opening of the cavity 100. The electric stirrer 3 is located on the cover 2 for stirring the coating in the cavity 100. The coating added to the cavity 100 is stirred by the electric stirrer 3.

[0026] The cover 2 has one or more inlets 200 for adding coating. The bottom of the reactor body 1 has an outlet 300 (valves are provided at the corresponding positions of the inlet 200 and outlet 300, which are not marked in the figure, but those skilled in the art should understand the installation and use of the valves, which will not be described in detail here). After the coating is stirred, it can be discharged from the outlet 300.

[0027] A sealing gasket 21 is fitted on the side of the cover 2. The sealing gasket 21 fits against the inner wall of the cavity 100, and the sealing gasket 21 on the side of the cover 2 can slide up and down along the inner wall of the cavity 100.

[0028] The cover 2 is also provided with a connecting hole (not marked in the figure). The location of the connecting hole on the cover 2 has no impact on the performance of this coating reactor.

[0029] The three-way connecting pipe 4 includes a first pipe opening 41, a second pipe opening 42, and a third pipe opening 43 arranged vertically from bottom to top. The vertical height interval between the first pipe opening 41, the second pipe opening 42, and the third pipe opening 43 is preferably set between 3cm and 10cm. The first pipe opening 41 is sealed to a connecting hole. The non-contact liquid level sensor 5 is sealed to the second pipe opening 42. The non-contact liquid level sensor 5 is used to detect the liquid level inside the three-way connecting pipe 4. When the non-contact liquid level sensor 5 detects that the paint liquid level has risen into the three-way connecting pipe 4, it sends liquid level information to the industrial controller 8. The setup and usage of the non-contact liquid level sensor 5 are conventional techniques in the field and will not be described in detail here. The vacuum pump 7 is sealed to the third pipe opening 43 via a flexible hose 6. The above-mentioned sealed connection method is existing technology and will not be described in detail here.

[0030] The inner wall of the cavity 100, the lower surface of the cover 2, and the inner wall of the tee connecting pipe 4 are all coated with an anti-stick coating (not shown in the figure). The anti-stick coating can be Teflon coating, DuPont coating, etc., which can effectively prevent the coating from sticking and make it easy to clean.

[0031] A viewing window 40 is also provided on the three-way connecting pipe 4. A transparent sheet (not marked in the figure) is sealed on the viewing window. The transparent sheet is made of glass or transparent resin. The bottom of the viewing window 40 is located above the first pipe opening 41, and the top of the viewing window 41 is located below the third pipe opening 43. The user can observe the liquid level of the coating in the three-way connecting pipe 4 through the transparent sheet of the viewing window 40.

[0032] The electric stirrer 3, non-contact liquid level sensor 5, vacuum pump 7, touch control screen 9, indicator light 10, and speaker 11 are electrically connected to the industrial controller 8. (The power supply terminals of the electric stirrer 3, vacuum pump 7, industrial controller 8, and touch control screen 9 are connected to the mains power supply through corresponding power adapters, which will not be described in detail here.) The electric stirrer 3, non-contact liquid level sensor 5, vacuum pump 7, industrial controller 8, touch control screen 9, indicator light 10, and speaker 11 are all existing electronic devices in the art. Those skilled in the art should understand the conventional selection and circuit connection methods of the above electronic devices, which will not be described in detail here. For example, the industrial controller 8 can be a Siemens S7-200 PLC controller.

[0033] When using this coating reactor, after the coating is added to the cavity 100, the industrial controller 8 can be operated via the touch control screen 9 to start the vacuum pump 7. At this time, the indicator light 10 will light up, indicating that the coating reactor has started working and is extracting air from the cavity 100, causing the cover 2 to move downward under atmospheric pressure until a small amount of coating overflows into the three-way connecting pipe 4. When the non-contact liquid level sensor 5 installed on the three-way connecting pipe 4 detects that the liquid level has risen to a certain position (the liquid level must be lower than the third pipe opening 43 to prevent the coating from being sucked into the vacuum pump 7), the vacuum pump 7 will stop extracting air. Then, the electric stirrer 3 can be controlled to stir the coating in the cavity 100 evenly.

[0034] After stirring is complete, the speaker 11 will issue a notification. The user can operate the industrial controller 8 via the touch control screen 9 to control the vacuum pump 7 to introduce air into the cavity 100 through the three-way connecting pipe 4, so that the air pressure in the cavity 100 is balanced with the atmospheric pressure, ensuring that the coating in the cavity 100 can be discharged normally from the discharge port 300 of the reactor body 1.

[0035] In addition, the cover 2 of this coating reactor can be removed from the reactor body 1, which facilitates cleaning the coating adhering to the reactor body 1, cover 2, electric stirrer 3, three-way connecting pipe 4 and hose 6.

[0036] Because the air in the 100-cubic-meter chamber is almost entirely expelled during stirring, the formation of air bubbles in the coating is greatly reduced. This coating reaction vessel is highly practical.

[0037] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
