Description

Technical Field

[0001] This utility model relates to the technical field of spraying device for eccentric valve processing and manufacturing, specifically a spraying device for eccentric valve processing and manufacturing. Background Technology

[0002] In modern industry, eccentric valves are widely used in various fluid control systems. Their performance and lifespan largely depend on the quality of surface treatment. Traditional surface treatment methods for eccentric valves mainly include manual painting, dip coating, and simple mechanical spraying. Eccentric valves mainly include eccentric butterfly valves, eccentric rotary regulating ball valves, and double eccentric hemispherical valves.

[0003] For example, application number CN202322532495.X, this utility model provides a painting device for butterfly valve production, including a collection cabinet, a spray box fixedly connected to the top of the collection cabinet, a spraying mechanism on the top of the spray box, several equidistant air inlets on the left side of the spray box, dustproof nets fixedly connected inside the air inlets, a defogging mechanism on the top right side of the spray box, a cabinet door rotatably connected to the front of the spray box, and a clamping and rotating mechanism at the bottom of the collection cabinet. This utility model, through the defogging mechanism, enables the collection of atomized paint particles during spraying, preventing workers from inhaling paint particles, ensuring their health, and improving the environmental friendliness of the painting device.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problems of collecting atomized paint particles during spraying, which could lead to workers inhaling these particles and harming their health, reducing the environmental friendliness of the spraying device used in butterfly valve production, and failing to collect excess paint during spraying, resulting in significant paint waste and increased production costs, the paint in the collection box will naturally dry and condense into a film over a long period of time. When the paint in the collection box is re-inhaled into the paint tank through the circulation device, this film will hinder the mixing of old and new paint, thereby reducing the quality of the paint and causing blockage of the spraying device.

This solves the problem that after long-term accumulation, the paint in the collection box will naturally dry and condense into a film. When the paint in the collection box is sucked back into the paint box through the circulation device, this film will hinder the mixing of old and new paint, resulting in a decrease in paint quality and clogging of the spraying device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for manufacturing eccentric valves, comprising a spraying box, a collecting box, a dripping hole, a paint tank, a spraying device, a circulation device, and a clamping device. The top of the collecting box is fixedly connected to the bottom of the spraying box. The dripping hole is located at the bottom of the inner wall of the spraying box, and the bottom of the inner wall of the dripping hole extends to the top of the inner wall of the collecting box. The bottom of the paint tank is fixedly connected to the top of the paint tank. The spraying device is located inside the spraying box, and the top of the spraying device extends to the top of the spraying box and is fixedly connected to the bottom of the paint tank. The right side of the circulation device is fixedly connected to the left side of the spraying box. A transfer box is provided at the bottom of the left side of the collecting box. The input end of the circulation device is fixedly connected to the bottom of the left side of the transfer box, and the output end of the circulation device is fixedly connected to the top of the left side of the paint tank. The bottom of the clamping device is fixedly connected to both sides of the bottom of the inner wall of the spraying box. A filter assembly is provided inside the transfer box, and plug-in assemblies are provided on both the front and rear sides of the inner wall of the transfer box.

[0007] In a preferred embodiment of this invention, the filter assembly includes a primary filter plate and a secondary filter plate. The surface of the primary filter plate is slidably connected to the right side of the interior of the transfer box, and the surface of the secondary filter plate is slidably connected to the left side of the interior of the transfer box.

[0008] As a preferred embodiment of this utility model, the plug-in assembly includes a slot, which is opened on both sides of the front and rear sides of the inner wall of the transfer box. A plug rod is slidably connected to the inner wall of the slot, and the inner side of the plug rod is fixedly connected to the front and back sides of the primary filter plate and the secondary filter plate.

[0009] As a preferred embodiment of this utility model, a water valve is fixedly connected to the bottom left side of the collection box, and the output end of the water valve is fixedly connected to the right side of the transfer box.

[0010] As a preferred embodiment of this utility model, a mesh frame box is fixedly connected to the bottom of both the left and right sides of the primary filter plate, and the surface of the mesh frame box is slidably connected to the inner wall of the transfer box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a transfer box, allows the paint to first enter the transfer box when the user starts the circulation device to return the accumulated paint in the collection box to the paint tank. After being filtered by the filter components inside the transfer box, the paint clumps that have solidified into a film are intercepted in the transfer box, allowing pure paint to return to the paint tank. This solves the problem that after long-term accumulation, the paint surface in the collection box will naturally dry and solidify into a film. When the paint in the collection box is sucked back into the paint tank by the circulation device, this film will hinder the mixing of old and new paint, resulting in a decrease in paint quality and clogging of the spraying device. This invention achieves the effect of auxiliary circulation filtration.

[0015] 2. This utility model, by setting up a filtration component, allows the paint in the transfer box to enter the transfer box and then return to the paint box through a circulation device. The paint entering the transfer box first passes through a primary filter plate for coarse filtration, intercepting large clumps of condensed paint. Then it passes through a secondary filter plate for filtration, intercepting fine clumps of condensed paint. Ultimately, the paint in the collection box is collected in a pure and reusable state and returned to the paint box through the circulation device.

[0016] 3. By setting up a plug-in assembly, when the user needs to filter the paint in the collection box using the primary and secondary filter plates, the transfer box is first opened, then the primary and secondary filter plates are held, and the plugs on both sides are aligned with the slots in the transfer box and inserted. The primary and secondary filter plates are then securely installed in the transfer box through the plug-in connection between the plugs and the slots. At the same time, the plug-in installation method facilitates the disassembly and installation of the primary and secondary filter plates in the transfer box, thereby improving the user's ease of operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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] like Figures 1 to 3 As shown, the present invention provides a spraying device 5 for manufacturing eccentric valves, comprising a spraying box 1, a collecting box 2, a dripping hole 3, a paint tank 4, a spraying device 5, a circulation device 6, and a clamping device 7. The top of the collecting box 2 is fixedly connected to the bottom of the spraying box 1. The dripping hole 3 is located at the bottom of the inner wall of the spraying box 1, and the bottom of the inner wall of the dripping hole 3 extends to the top of the inner wall of the collecting box 2. The bottom of the paint tank 4 is fixedly connected to the top of the paint tank 4. The spraying device 5 is located inside the spraying box 1, and the top of the spraying device 5 extends to the bottom of the inner wall of the collecting box 1. The top of the spray box 1 is fixedly connected to the bottom of the paint box 4. The right side of the circulation device 6 is fixedly connected to the left side of the spray box 1. A transfer box 8 is provided at the bottom of the left side of the collection box 2. The input end of the circulation device 6 is fixedly connected to the bottom of the left side of the transfer box 8. The output end of the circulation device 6 is fixedly connected to the top of the left side of the paint box 4. The bottom of the clamping device 7 is fixedly connected to both sides of the bottom of the inner wall of the spray box 1. A filter assembly 9 is provided inside the transfer box 8. Insertion assemblies 10 are provided on both the front and rear sides of the inner wall of the transfer box 8.

[0023] refer to Figure 2 The filter assembly 9 includes a primary filter plate 91 and a secondary filter plate 92. The surface of the primary filter plate 91 is slidably connected to the right side of the interior of the transfer box 8, and the surface of the secondary filter plate 92 is slidably connected to the left side of the interior of the transfer box 8.

[0024] As a technical optimization of this utility model, by setting up a filter component 9, when the paint in the transfer box 8 enters the transfer box 8 and is circulated back to the paint box 4 by the circulation device 6, the paint entering the transfer box 8 first passes through the coarse filtration of the primary filter plate 91 to intercept large clumps of condensed paint, and then passes through the secondary filter plate 92 to intercept fine clumps of condensed paint. Finally, the paint in the collection box 2 is returned to the paint box 4 in a pure and recyclable state through the circulation device 6.

[0025] refer to Figure 2 The plug-in assembly 10 includes a slot 101, which is opened on both sides of the front and rear sides of the inner wall of the transfer box 8. A plug rod 102 is slidably connected to the inner wall of the slot 101. The inner side of the plug rod 102 is fixedly connected to the front and back sides of the primary filter plate 91 and the secondary filter plate 92.

[0026] As a technical optimization of this utility model, by setting up the plug-in component 10, when the user needs to use the primary filter plate 91 and the secondary filter plate 92 to filter the paint in the collection box 2, the transfer box 8 is first opened, and then the primary filter plate 91 and the secondary filter plate 92 are held, and the plug rods 102 on both sides are aligned with the slots 101 in the transfer box 8 and inserted. Then, through the plug-in method of the plug rods 102 and the slots 101, the primary filter plate 91 and the secondary filter plate 92 are securely installed in the transfer box 8. At the same time, the plug-in installation method makes it easy to disassemble and install the primary filter plate 91 and the secondary filter plate 92 in the transfer box 8, thereby improving the user's ease of operation.

[0027] refer to Figure 1 and Figure 3 A water valve 11 is fixedly connected to the bottom left side of the collection box 2, and the output end of the water valve 11 is fixedly connected to the right side of the transfer box 8.

[0028] As a technical optimization of this utility model, a water valve 11 is set up to connect the collection box 2 and the transfer box 8 as an intermediary. The opening or closing of the water valve 11 controls whether the paint in the collection box 2 flows into the transfer box 8. Thus, when the paint is accumulated in the collection box 2, the paint will not flow into the transfer box 8, thereby preventing some of the paint from flowing into the transfer box 8 and drying out, thus losing the filtering effect.

[0029] refer to Figure 2 The bottom of the left and right sides of the primary filter plate 91 is fixedly connected to a mesh frame box 12, and the surface of the mesh frame box 12 is slidably connected to the inner wall of the transfer box 8.

[0030] As a technical optimization of this utility model, by setting up the mesh frame box 12, when the paint in the collection box 2 enters the transfer box 8, after being filtered by the primary filter plate 91 and the secondary filter plate 92, the filtered paint clumps will naturally fall into the mesh frame box 12 when there is no flowing paint in the transfer box 8. This makes it convenient to remove the filtered paint clumps when the primary filter plate 91 and the secondary filter plate 92 are pulled out of the transfer box 8 for cleaning after the filtration work is completed, thereby improving the user's work efficiency.

[0031] refer to Figure 2 A rectangular triangular scraper 13 is fixedly connected to the top of the wire mesh box 12, and the surface of the rectangular triangular scraper 13 is in contact with the inner wall of the transfer box 8.

[0032] As a technical optimization of this utility model, by setting a triangular scraper, when the user pulls the primary filter plate 91 and the secondary filter plate 92 out of the transfer box 8 and pulls out the mesh frame box 12 together, the rectangular triangular scraper 13 on the top of the mesh frame box 12 will scrape against the inner wall of the collection box 2 to remove the paint clumps adhering to the inner wall of the transfer box 8, thereby further improving the user's ease of operation.

[0033] refer to Figure 1 The collection box 2 has an installation slot 14 on the left side of the front, and a transparent observation window 15 is fixedly connected to the inner wall of the installation slot 14.

[0034] As a technical optimization of this utility model, by setting the installation slot 14 and the transparent observation window 15, when the collection box 2 collects excess paint during daily spraying, the user can directly observe the amount of paint accumulated in the collection box 2 through the transparent observation window 15 in the installation slot 14, so that the user can determine whether the circulation device 6 can be activated to transport the paint in the collection box 2 back to the paint box 4.

[0035] The working principle and usage process of this utility model are as follows: When the user needs to paint the surface of the eccentric valve, first fill the paint spraying tank with paint, then open the spraying tank 1, clamp the eccentric valve with the clamping device 7 and drive it to rotate, then close the spraying tank 1, start the spraying device 5 to atomize and spray the paint in the paint tank 4, evenly spraying it on the surface of the eccentric valve. During the spraying process, excess paint falls into the collection tank 2 through the drip hole 3 for collection. After large-scale and long-term spraying of the eccentric valve, when the user can see through the transparent observation window 15 that the paint in the collection tank 2 has accumulated to a level that can be recycled, open the transfer box 8, then hold the primary filter plate 91 and the secondary filter plate 92, align the insert rods 102 on both sides with the slots 101 in the transfer box 8 and insert them. The insertion method of the insert rods 102 and slots 101 is as follows: Securely install the primary filter plate 91 and the secondary filter plate 92 inside the transfer box 8. Then, close the transfer box 8 and open the water valve 11 to allow the paint in the transfer box 8 to flow into the transfer box 8 through the water valve 11. At this time, start the circulation device 6 to gradually pump the paint out of the transfer box 8. Meanwhile, the paint in the collection box 2 first passes through the primary filter plate 91 for coarse filtration, intercepting large pieces of condensed paint. Then, it passes through the secondary filter plate 92 for filtration, intercepting small particles of condensed paint. Finally, the pure, recyclable paint is transported back to the paint tank 4 by the circulation device 6. This completes the filtration of the paint and prevents the paint from accumulating over a long period of time, drying naturally, and forming a film that breaks into fragments and returns to the paint tank 4. This prevents the paint from mixing with new paint, reducing its quality, and causing blockage of the spraying device 5. This provides the advantage of auxiliary circulation filtration.

[0036] In summary, this spraying device for manufacturing eccentric valves, by setting up a transfer box 8, allows the paint to first enter the transfer box 8 when the user starts the circulation device 6 to re-transport the paint accumulated in the collection box 2 back to the paint box 4. After being filtered by the filter component 9 inside the transfer box 8, the paint particles that have condensed into a film are intercepted in the transfer box 8, allowing pure paint to return to the paint box 4. This solves the problem that after long-term accumulation of paint in the collection box, the paint surface will naturally dry and condense into a film. Subsequently, when the paint in the collection box is re-inhaled into the paint box by the circulation device, this film will hinder the mixing of old and new paint, resulting in a decrease in paint quality and clogging of the spraying device.
