[0001] This utility model relates to the field of reaction vessels, and in particular to a raw material reaction vessel for cathode electrophoretic paint processing. Background Technology

[0002] Electrophoresis is a common process in coating metal workpieces. Electrophoretic paint, also called electrophoretic coating, is used by placing the workpiece as an electrode in a paint tank diluted with water.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Referring to Figures 1-4, a raw material reaction vessel for cathodic electrophoretic coating processing includes a base plate 1, an insulation box 2 fixedly connected to the upper side of the base plate 1, a reaction vessel body 3 fixedly connected to the inner bottom wall of the insulation box 2, a sealing cover 4 detachably connected to the upper side of the reaction vessel body 3, a stirring motor 5 fixedly connected to the upper side of the sealing cover 4, the output end of the stirring motor 5 penetrating the inner top wall of the sealing cover 4 and fixedly connected to a drive shaft 6, a heating stirring shaft 7 fixedly connected to the surface of the drive shaft 6, and an atomizing and impurity removal mechanism fixedly connected to the upper side of the base plate 1.

[0023] The atomizing and impurity removal mechanism includes a liquid storage box 9 fixedly connected to the upper side of the base plate 1, an installation box 10 fixedly connected to the upper side of the liquid storage box 9, an atomizing component fixedly connected to the right side of the installation box 10, an airbag 11 fixedly connected to the inner bottom wall of the installation box 10, an air inlet hole opened on the rear side of the airbag 11, and an air inlet pipe 16 fixedly connected to the inner wall of the air inlet hole.

[0024] Using the above structure, a commonly used reactor is formed by setting the base plate 1 as an installation platform, the reactor body 3 and the sealing cover 4, and the insulation box 2 with four legs to raise the reactor.

The stirring motor 5 drives the drive shaft 6 to rotate, and the heating stirring shaft 7 is used to stir and mix the raw materials. The heating stirring rod is embedded with a resistance heating wire to heat the raw materials. Since the pressure change of the reactor inner wall is small, the flow rate of the exhaust gas entering the atomization and purification mechanism is fixed, and a certain amount of exhaust gas can be separated and purified.

[0025] Preferably, the end of the air inlet pipe 16 away from the airbag 11 passes through the inner top wall of the sealing cover 4. A first timing control valve 17 is fixedly connected to the surface of the air inlet pipe 16. A reaction box 18 is fixedly connected to the right side of the mounting box 10.

A second timing control valve 20 is fixedly connected to the surface of the air supply pipe 19.

[0026] The timing of exhaust gas entering the intake pipe 16 is controlled by setting the first timing control valve 17. When the first timing control valve 17 is open and the second timing control valve 20 is closed, the exhaust gas enters the air bag 11, causing the air bag 11 to inflate. When the first timing control valve 17 is closed and the second timing control valve 20 is open, the exhaust gas in the air bag 11 is injected into the reaction box 18.

[0027] Preferably, a discharge hole is provided on the lower side of the reactor body 3, and a discharge pipe 8 is fixedly connected to the inner wall of the discharge hole.

[0028] The installation of a discharge pipe 8 with a valve facilitates the collection of processed raw materials from the reactor body 3 by staff.

[0029] Preferably, a pad 12 is slidably connected to the inner wall of the mounting box 10, and a compression spring 13 is fixedly connected to the upper side of the pad 12. The top end of the compression spring 13 is fixedly connected to the inner top wall of the mounting box 10. A mounting slide 14 is provided on the right side of the mounting box 10. A connecting strip 15 is slidably connected to the inner wall of the mounting slide 14, and the lower side of the connecting strip 15 is fixedly connected to the upper side of the pad 12.

[0030] By setting the base plate 1, the elastic force applied by multiple compression springs 13 is evenly applied to the airbag 11, and the volume change of the airbag 11 can drive the connecting strip 15 to move.

[0031] Preferably, the atomizing assembly includes a sleeve 22 fixedly connected to the right side of the mounting box 10. A piston 23 is slidably connected to the inner wall of the sleeve 22. A pushing hole is opened on the upper side of the sleeve 22. A pushing rod 24 is slidably connected to the inner wall of the pushing hole. A return spring 25 is sleeved on the surface of the pushing rod 24. The top end of the return spring 25 is fixedly connected to the inner top wall of the sleeve 22. The bottom end of the return spring 25 is fixedly connected to the upper side of the piston 23. The top end of the pushing rod 24 is fixedly connected to the lower side of the connecting strip 15.

[0032] By setting a return spring 25 to help the piston 23 quickly return to its original position, when the airbag 11 shrinks, the pad 12 drives the connecting strip 15 to move, and the movement of the connecting strip 15 drives the push rod 24 to move. The return spring 25 allows the piston 23 to move downwards more quickly.

[0033] Preferably, a water suction hole is provided on the lower side of the sleeve 22, and a water suction pipe 26 is fixedly connected to the inner wall of the water suction hole. A water suction one-way valve 27 is fixedly connected to the surface of the water suction pipe 26. The end of the water suction pipe 26 away from the sleeve 22 passes through the front inner wall of the liquid storage box 9. A water outlet hole is provided on the lower side of the sleeve 22, and a water outlet pipe 28 is fixedly connected to the inner wall of the water outlet hole.

The end of the water outlet pipe 28 away from the sleeve 22 passes through the inner top wall of the reaction box 18 and is fixedly connected to an atomizing nozzle.

[0034] By setting the water intake check valve 27 and the water outlet check valve 29, the flow direction of the decomposing agent can be restricted. When the piston 23 moves upward, the decomposing agent in the storage box 9 is drawn into the sleeve 22. When the piston 23 moves downward, the decomposing agent in the sleeve 22 is injected into the reaction box 18.

[0035] The working principle of this utility model is as follows: A raw material reaction vessel for cathodic electrophoretic paint processing is opened, the sealing cover 4 is opened, the raw material is put into the reaction vessel body 3, the sealing cover 4 is closed, the stirring motor 5 is started, and the raw material is heated and mixed in the reaction vessel body 3. Then, the opening and closing of the first timing control valve 17 and the second timing control valve 20 are controlled to fill the air bag 11 with waste gas. When the air bag 11 expands, the pressure plate 12 moves upward. At this time, the compression spring 13 is compressed, the movement of the pressure plate 12 drives the connecting strip 15 to move upward, the movement of the connecting strip 15 drives the push rod 24 to move, and the movement of the push rod 24 drives the piston 23 to move upward. Due to the limitation of the water suction check valve 27 and the water discharge check valve 29, The decomposition liquid in the storage box 9 is drawn into the sleeve 22 through the suction pipe 26. When the air bag 11 shrinks, the pad 12 moves downward under the action of the compression spring 13. The movement of the pad 12 drives the connecting strip 15 to move downward. The movement of the connecting strip 15 drives the push rod 24 to move. The movement of the push rod 24 drives the piston 23 to move downward. Due to the restriction of the suction one-way valve 27 and the outlet one-way valve 29, the decomposition liquid in the sleeve 22 is injected into the reaction box 18 through the outlet pipe 28. Under the action of the atomizing nozzle, water mist is formed and fully contacts the exhaust gas, mixing impurities and harmful substances with the water mist. The mixture flows into the collection cup 31 through the outlet hole 30, allowing the harmless gas to be discharged through the exhaust hole 21.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
