Description

Technical Field

[0001] This utility model belongs to the technical field of spraying equipment, specifically relating to a spiral centrifugal pump processing spraying device. Background Technology

[0002] A spiral centrifugal pump is a special type of pump that combines the advantages of traditional centrifugal pumps and positive displacement pumps. It is particularly suitable for applications that require handling fluids containing large particles, long fibers, or high viscosity. A spiral centrifugal pump mainly consists of components such as a pump casing, a spiral centrifugal impeller, a shaft, and a base. The pump casing and base both require external coating.

[0003] The existing method for spraying the pump casing of a spiral centrifugal pump usually involves using a clamp to hold and fix the pump casing, followed by spraying with a spray gun. However, obstructions may occur in the clamping area, requiring readjustment of the clamping position and spraying of the obstructed area. This is time-consuming, labor-intensive, and reduces the spraying effect. Furthermore, after spraying, the clamp must be released, the pump casing removed, a new pump casing loaded, and then clamped and fixed again. This requires frequent clamping and releasing of the clamp, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

The second spring is located between the baffle and the inner wall of the fixed cylinder, and a slide rail is fixedly installed at the other end of the movable rod after it movably passes through the center of the end face of the fixed cylinder.

[0011] Preferably, the slide rail has a groove in the middle, and a movable block is slidably connected inside the groove.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example

[0021] Please see Figure 1 A spiral centrifugal pump processing and spraying device includes a workbench 1, a rotating mechanism 5 in the middle of the workbench 1, a clamping mechanism 2 for spraying the spiral centrifugal pump housing on the top of the rotating mechanism 5, a fixed frame 3 fixedly installed on the rear side of the workbench 1, a spraying mechanism 4 installed on the fixed frame 3, and support legs 6 fixedly installed at the four corners of the bottom of the workbench 1.

[0022] In use, the clamping mechanism 2 is used to stably clamp the spiral centrifugal pump housing from the inside out, the spraying mechanism 4 is used to achieve uniform spraying of the spiral centrifugal pump housing, the rotating mechanism 5 is used to drive the spiral centrifugal pump housing to rotate automatically, and the support leg 6 is used to support the fixed worktable 1.

[0023] Please see Figure 1 , Figure 3 and Figure 4The clamping mechanism 2 includes a pressing component 21 and a clamping component 22. The clamping component 22 is mounted on the rotating disk 51, and the pressing component 21 is mounted on the clamping component 22. The pressing component 21 includes a mounting cylinder 211 fixedly connected to the top of the rotating disk 51. Several fixed cylinders 216 are evenly fixedly mounted on the outer wall of the middle part of the mounting cylinder 211. A lifting rod 212 slides through the center of the top of the mounting cylinder 211. A top plate 213 is fixedly mounted on the top of the lifting rod 212. A first spring 214 is sleeved in the middle of the lifting rod 212. The first spring 214 is located between the top plate 213 and the top of the mounting cylinder 211. The bottom of the lifting rod 212 is located inside the mounting cylinder 211, and a pressing head 215 is fixedly mounted on the bottom of the lifting rod 212.

[0024] Please see Figure 1 , Figure 3 and Figure 4 The clamping assembly 22 includes a movable rod 226 that movably penetrates the end face of the fixed cylinder 216. The movable rod 226 movably penetrates the interior of the mounting cylinder 211, and a pressure ball 227 that cooperates with the extrusion head 215 is fixedly installed at one end of the movable rod 226. A baffle 225 is fixedly sleeved in the middle of the movable rod 226, and a second spring 224 is sleeved on the outside of the movable rod 226. The second spring 224 is located between the baffle 225 and the inner wall of the fixed cylinder 216. The other end of the movable rod 226 movably penetrates the center of the end face of the fixed cylinder 216 and is fixedly installed with a slide rail 223. A sliding groove is provided in the middle, and a movable block 220 is slidably connected inside the sliding groove. A telescopic rod 222 is fixedly installed at the end of the movable block 220 away from the mounting cylinder 211. The telescopic rod 222 slides through the slide rail 223 on the side away from the mounting cylinder 211 and is fixedly installed on a fixing plate 221. An anti-slip pad is fixedly installed on the fixing plate 221. Several anti-slip grooves are evenly provided on the anti-slip pad. Screws 228 are fixedly installed on both sides of the movable block 220 perpendicular to the length direction of the sliding groove. Nuts are threaded onto both screws 228, and both nuts are in contact with the slide rail 223.

[0025] During use, the clamping mechanism 2 first places the spiral centrifugal pump housing to be clamped onto the top plate 213. The weight of the spiral centrifugal pump housing causes the top plate 213 and its lifting rod 212 to move downwards, simultaneously causing the extrusion head 215 to move downwards and compressing the first spring 214. As the extrusion head 215 extrudes, it causes the pressure ball 227 and its movable rod 226 to move away from the axis of the mounting cylinder 211, and simultaneously causes the baffle 225 and its slide rail 223 to move away from the axis of the mounting cylinder 211. The movement along the axis compresses the second spring 224, which in turn drives the movable block 220 and its telescopic rod 222 to move away from the axis of the mounting cylinder 211. Simultaneously, it drives the fixed plate 221 to move away from the axis of the mounting cylinder 211. At this time, the mounting cylinder 211 and its anti-slip pads clamp and fix the inside of the spiral centrifugal pump housing, achieving stable clamping of the spiral centrifugal pump housing from the inside out. When disassembly is required, the spiral centrifugal pump housing can be disassembled by simply pulling it upward, saving time and effort.

[0026] Please see Figure 1 and Figure 3 The rotating mechanism 5 includes a servo motor 52 fixedly connected to the bottom of the workbench 1. The output end of the servo motor 52 is fixedly sleeved with a drive bevel gear 53. A linkage rod 54 rotates through the center of the top of the workbench 1. A rotating disk 51 is fixedly installed on the top of the linkage rod 54. A driven bevel gear 55 that meshes with the drive bevel gear 53 is fixedly sleeved on the bottom of the linkage rod 54.

[0027] In use, between spraying operations, the servo motor 52 is started. The output of the servo motor 52 drives the active bevel gear 53 to rotate, which in turn drives the driven bevel gear 55 to rotate. At the same time, it drives the linkage rod 54 and the rotating disk 51 on it to rotate, which in turn drives the clamping mechanism 2 and the spiral centrifugal pump housing clamped on it to rotate.

[0028] Please see Figure 1 and Figure 2 The spraying mechanism 4 includes a flow divider plate 44 fixedly connected to the inner side of the fixed frame 3. Several nozzles 45 are evenly fixedly installed on the side of the flow divider plate 44 near the workbench 1. A water supply pipe 43 is fixedly installed on the bottom right side of the flow divider plate 44. A water pump 42 is fixedly installed on the end of the water supply pipe 43 away from the flow divider plate 44. The water pump 42 is located on the bottom surface inside the storage tank 41. A feed pipe 7 is provided on the top right side of the storage tank 41. A valve is fixedly installed on the feed pipe 7.

[0029] When in use, start the water pump 42. The water pump 42 transports the paint stored in the storage tank 41 to the diverter plate 44 through the water pipe 43. After being diverted by the diverter plate 44, the paint is sprayed out from the nozzle 45, which uniformly coats the rotating spiral centrifugal pump housing.

[0030] It should be noted that, in use, the spiral centrifugal pump processing and spraying device first places the spiral centrifugal pump housing to be clamped and fixed onto the top plate 213. The weight of the spiral centrifugal pump housing drives the top plate 213 and the lifting rod 212 on it to move downwards, simultaneously driving the extrusion head 215 to move downwards and compressing the first spring 214. At this time, as the extrusion head 215 extrudes, it drives the pressure ball 227 and the movable rod 226 on it to move away from the axis of the mounting cylinder 211, and simultaneously drives the baffle 225 and the slide rail 223 on it to move away from the axis of the mounting cylinder 211. The spiral centrifugal pump housing moves in the direction of the rotation, compressing the second spring 224. This, in turn, drives the movable block 220 and its telescopic rod 222 to move away from the axis of the mounting cylinder 211. Simultaneously, it drives the fixed plate 221 to move away from the axis of the mounting cylinder 211. At this time, the mounting cylinder 211 and its anti-slip pads clamp and fix the inside of the spiral centrifugal pump housing. Then, the rotating mechanism 5 is used to achieve uniform rotation of the spiral centrifugal pump housing. Subsequently, the spraying mechanism 4 is used to uniformly spray the rotating spiral centrifugal pump housing. After the spraying is completed, the spiral centrifugal pump housing can be directly removed.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
