Description

Technical Field

[0001] This utility model relates to the technical field of spray painting equipment, specifically a spray painting device for centrifugal pump processing. Background Technology

[0002] A centrifugal pump is a machine used to transport or pressurize liquids and slurries. It transfers mechanical energy or other external energy to the internal liquid or slurry to perform work. Because the pump body components are frequently in contact with various liquid substances, especially when transporting liquids with high sand content and corrosive slurries, the damage rate of pump body components is very high. Therefore, rust and corrosion prevention treatment of the pump body is an essential part of the centrifugal pump manufacturing process. Centrifugal pumps usually require painting equipment for treatment during the manufacturing process.

[0003] However, current painting equipment typically uses a spraying method for painting. Excess paint flows along the surface of the centrifugal pump and is discharged, requiring the centrifugal pump to add a large amount of paint during painting, thus increasing the cost of paint and affecting the painting effect of the centrifugal pump. Summary of the Invention

It combines a fixed plate, filter holes, a recovery hopper, a pump body, a feed pipe, a housing, a recovery pipe, a feed inlet, a support frame, and a spray nozzle. When the pump body is operating, paint from inside the housing enters the paint tank and sprays paint onto the surface of the centrifugal pump housing. Excess paint is filtered through the filter holes and returned to the housing for recycling. This process can be repeated to achieve multiple painting effects. This method reduces paint costs, improves the painting effect of the centrifugal pump, and solves the problems mentioned in the background technology.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By using a combination of a fixed plate, filter holes, recovery hopper, pump body, feed pipe, housing, recovery pipe, feed port, support frame, and spray nozzle, the paint in the housing enters the paint tank when the pump body is working and sprays paint onto the surface of the centrifugal pump housing.

[0022] 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.

[0023] Example

[0024] Reference Figure 1-4 As shown, a spray painting device for centrifugal pump processing includes a paint can body 1 and a housing 216. A feed inlet 218 is provided at the top of the housing 216. A nozzle 220 is installed on the inner wall of the top of the paint can body 1. A pump body 214 corresponding to the nozzle 220 is installed on the outer wall of the top of the paint can body 1. The input end of the pump body 214 is connected to the inside of the housing 216 via a feed pipe 215. A recovery hopper 213 is fixed at the bottom of the paint can body 1. The bottom end of the recovery hopper 213 is connected to the inside of the housing 216 via a recovery pipe 217. By turning on the pump body 214, the paint inside the housing 216 is sprayed out through the feed pipe 215 and the nozzle 220. A centrifugal pump is placed inside the paint can body 1, and the sprayed paint can coat the surface of the centrifugal pump. Excess paint flows downwards and, under the action of the recovery hopper 213 and the recovery pipe 217, flows back into the housing 216, thus achieving the purpose of recycling. This method can reduce the initial amount of paint added, achieving the effect of cost saving. A fixing plate 211 is fixed to the inner wall of the paint can body 1. The fixing plate 211 has several sets of filter holes 212 inside. These filter holes 212 filter impurities from the paint, allowing large particles to be supported on the fixing plate 211, while the paint passes through the filter holes 212 into the recovery hopper 213. Three sets of support frames 219 are fixed to the outer wall of the paint can body 1. These three sets of support frames 219 are evenly spaced circumferentially distributed along the axis of the paint can body 1, providing support and stability during use.

[0025] A baffle 317 is installed on the inner wall of the paint can body 1, and a handle 318 is fixed on the outer wall of the baffle 317. The baffle 317 is detachably connected to the paint can body 1. The specific disassembly method can be the existing connection method such as bolt connection, which makes it easy to open and take out the centrifugal pump. The handle 318 makes it easier to operate the baffle 317 more comfortably.

[0026] The paint can body 1 has two sets of symmetrical clamping mechanisms inside. A motor 316 is installed on the outer wall of the paint can body 1. The output end of the motor 316 is connected to any one of the clamping mechanisms. The clamping mechanism can clamp and fix the centrifugal pump. After the motor 316 is turned on, it can drive any one of the clamping mechanisms to rotate, thereby driving the clamped centrifugal pump and the other clamping mechanism to rotate, so that the centrifugal pump can correspond to the spray head 220 in multiple directions to achieve the purpose of multi-angle painting.

[0027] The clamping mechanism includes a rotating rod 311, a limiting frame 312, a groove 313, a hydraulic rod 314, and a clamping plate 315. One end of the rotating rod 311 is rotatably connected to the inner wall of the paint can body 1, and the other end is fixed to the limiting frame 312. The limiting frame 312 has a groove 313 inside. The hydraulic rod 314 is installed at the top of the limiting frame 312 and its output end is connected to the clamping plate 315 located inside the groove 313. The output end of the motor 316 is connected to any set of rotating rods 311. By inserting the centrifugal pump housing into the groove 313, the hydraulic rod 314 is opened and the clamping plate 315 is driven to press down. The clamping plate 315 can clamp and position the centrifugal pump housing. The bottom of the clamping plate 315 can be made of rubber, which has good wear resistance and anti-slip properties, ensuring that the centrifugal pump housing is not easy to fall off, and can also increase the contact area between the centrifugal pump housing and the paint.

[0028] Working principle: When needed, paint is added into the housing 216 through the feed port 218. Then, the centrifugal pump housing is placed between the two sets of grooves 313 by opening the baffle 317. The clamping plate 315 is pressed down by opening the hydraulic rod 314, which clamps and positions the centrifugal pump housing. Then, the pump body 214 is opened, and the paint inside the housing 216 is sprayed into the paint can body 1 through the feed pipe 215 and the nozzle 220, and the surface of the centrifugal pump housing is painted. Excess paint can slide down the surface of the centrifugal pump, be screened through the filter hole 212, and be guided into the housing 216 for recycling under the action of the recovery hopper 213 and the recovery pipe 217, so as to save paint.

[0029] Subsequently, the motor 316 is turned on to drive the rotating rod 311, the limit frame 312, the hydraulic rod 314, the clamping plate 315 and the clamped centrifugal pump to rotate, so as to achieve the purpose of all-round spraying and enhance the painting effect of the centrifugal pump housing.
