Description

Technical Field

[0001] The invention relates to the technical field of magnetic pump casing processing, and in particular to a spraying device for pump casing processing. Background Art

[0002] The magnetic drive pump is mainly composed of several parts such as the pump head, magnetic transmission (magnetic cylinder), motor, and connecting base plate. The magnetic transmission of the magnetic pump is composed of an outer magnetic rotor, an inner magnetic rotor, and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic materials, driving the inner magnetic rotor connected to the impeller to rotate synchronously, realizing contactless synchronous transmission of power, and converting the dynamic sealing structure that is prone to leakage into a static sealing structure with zero leakage. During the processing of the magnetic pump, the pump housing needs to be sprayed by a spraying device to improve its anti-corrosion and anti-rust performance.

[0003] During use of the existing spray device for pump casing processing, the nozzle is an evenly distributed structure. During the spraying process, effective spraying is achieved through uniform spraying. However, the outer wall of the pump casing is not a planar structure, and there are grooves at certain positions. The grooves are relatively deep. When spraying with a conventional nozzle, the paint cannot be sprayed smoothly into the grooves, which will result in incomplete spraying of the outer wall of the pump casing and reduce the use value of the spray device.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] A spraying device for pump casing processing disclosed in the present invention is mainly applied to the existing spraying device for pump casing processing. During use, the nozzle is an evenly distributed structure. During the spraying process, effective spraying is achieved by uniform spraying. However, the outer wall of the pump casing is not a planar structure. There are grooves at certain positions thereof, and the grooves are relatively deep. When spraying with a conventional nozzle, the paint cannot be sprayed smoothly into the grooves, which will result in incomplete spraying of the outer wall of the pump casing.

[0035] Reference Figure 1-Figure 11 A spraying device for pump casing processing includes a grounding seat 1 and a sleeve frame 5. The outer wall of the sleeve frame 5 is provided with a mounting hole 21, and the interior of the mounting hole 21 is fixedly connected to a fixing frame 10. The inner wall of the fixing frame 10 is annularly distributed with adjustment rails 15. An adjustment slider 18 is slidably connected to the interior of each adjustment rail 15. The outer sides of multiple adjustment sliders 18 are fixedly connected to the same delivery pipe 19. One end of the delivery pipe 19 is provided with a constant angle adjustment frame 16. The constant angle adjustment frame 16 includes a shunt pipe 1601 and a semicircular guide rail 1604. The semicircular guide rail 1604 is provided with a specific nozzle 17. The specific nozzle 17 includes a flow inlet frame 1702. A slider 2 1703 is fixedly connected to one side of the flow-integrating frame 1702, and the slider 2 1703 is slidably connected to the inside of the semicircular guide rail 1604. An annular connecting hole is opened on the other side of the flow-integrating frame 1702, and a peripheral spray plate 1701 is fixedly connected to the inside of the annular connecting hole.

During the operation of the micro spray gun 1710, the extraction pump 1715 is started, and the extraction pump 1715 mixes part of the paint and air, and sprays it through the pressurized hole 1709, thereby impacting the paint sprayed into the inside of the groove, so that it is evenly sprayed to various positions of the groove. At the same time, the paint mixed in the air also has a spraying effect, ensuring that the inside of the groove is completely sprayed, thereby improving the use value of the spraying device.

During the spraying process, when the camera 1612 feeds back the captured image to the image analyzer 1610 and interprets it as a groove shape, the constant angle adjustment frame 16 drives the specific nozzle 17 to rotate 72° so that the specific nozzle 17 points to the pump housing, the solenoid valve 1617 is closed, and the solenoid valve 2 1705 is opened, then the paint is sprayed to the inside of the groove through each micro spray gun 1710, and part of the paint is sprayed to the outer position of the groove through each spray hole 1706 on the peripheral spray plate 1701. During the operation of the micro spray gun 1710, the extraction pump 1715 is started, and the extraction pump 1715 mixes part of the paint and air, and sprays it through the pressurized hole 1709, thereby impacting the paint sprayed into the inside of the groove, so that it is evenly sprayed to various positions of the groove. After the groove spraying is completed, the constant angle adjustment frame 16 drives the conventional nozzle 1603 to reset and continue the spraying operation.
