Description

Technical Field

[0001] The utility model belongs to the technical field of acid-resistant pumps, in particular to a pump body structure of an ultra-high molecular weight polyethylene acid-resistant pump. Background Art

[0002] The pump body of the ultra-high molecular weight polyethylene acid-resistant pump is a key component of the pump. It is usually made of ultra-high molecular weight polyethylene material, which gives the pump body excellent acid resistance and can work stably for a long time in an acidic environment. The pump body as a whole shows a specific shape and structure, with an inner cavity for fluid flow, providing space for the transmission of the medium; there is also an area specifically for accommodating the impeller to ensure that the impeller can rotate efficiently in it to push the fluid; the pump body is also provided with an inlet and outlet for the suction and discharge of the fluid. At the same time, it has a certain strength and stability to cope with various pressures and forces that occur during the working process, ensuring that the pump can operate safely and reliably, thereby giving full play to the important role of ultra-high molecular weight polyethylene acid-resistant pumps in related industrial fields;

[0003] The Chinese patent with the publication number of "CN214533562U" discloses an anti-corrosion and acid-resistant pump for producing environmentally friendly water treatment agents, which comprises a pump body, an acid-base neutralization box is installed on the pump body, a connecting pipe is connected to the bottom of the acid-base neutralization box, an electric telescopic rod is installed on the outside of the pump body, a connecting plate is connected to the top of the electric telescopic rod, a spray pipe is connected to the bottom of the other end of the connecting plate, a liquid cavity is opened inside the spray pipe, and a sealing plate is connected to one end of the spray pipe located inside the pump body. The utility model uses the acid-base neutralization box, the electric telescopic rod and the spray pipe. When the industrial pump is stopped, the electric telescopic rod will drive the inner end of the spray pipe to extend into the pump body. At the same time, the acid-base neutralization box sprays the acid-base neutralization liquid through the spray hole on the spray pipe to spray and clean the inside of the pump body, so as to achieve the neutralization of the residual liquid, avoid the residual liquid from damaging the pump pipe, and further reduce the service life of the pump body, thereby improving the reliability of the device;

[0004] Although the pump body of the ultra-high molecular weight polyethylene acid-resistant pump has good acid resistance, there are still certain defects and shortcomings in its specific application process. First, during the use of the above-mentioned technical solution, bolts are used at the end of the acid-resistant pump to assist in the installation of the filter screen structure. When disassembly and maintenance are required, it is obviously not convenient to quickly complete the disassembly and maintenance of the filter screen. Moreover, during its use, the installation structure lacks a buffer and anti-seismic structure, and there is also a lack of corresponding protective buffer structure during the overall application period. It is easy to generate noise during use, and it is also easy to cause damage to the inside of the equipment. It can be seen that there are certain defects and shortcomings as a whole.

[0005] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide an ultra-high molecular weight polyethylene acid-resistant pump body structure to solve the problems raised by the background technology.

When the acid-resistant pump is in use, the buffer spring can assist in buffering and shock absorption to improve its protection performance. At the same time, because there is a damper, it can cooperate with the buffer spring to perform buffering and damping, reduce the amplitude of the buffer spring, and enhance the overall stability of the device. This makes the device highly seismic when used, which not only improves the seismic resistance of the acid-resistant pump body, but also reduces the operating noise, greatly improving the convenience of use.

When installing, insert the slide plate into the slide groove, flip the hinged frame to make it dock, and reset the limit spring to allow the plug plate to be inserted into the limit frame. The plug plate and the limit frame are limited to clamp and install, which facilitates the rapid disassembly and assembly of the filter screen, greatly facilitates inspection and maintenance, and makes the use and maintenance of the entire device more convenient and efficient.

[0032] Principle and advantages of use: By setting the anti-blocking mechanism 3, the device can be connected to an external pipeline through the mounting flange 6 during use. When the acid-resistant pump body 1 is in operation, the filter screen 34 can be used to assist in filtering the liquid flowing inside the acid-resistant pump body 1. When the filter screen 34 needs to be disassembled for maintenance, the limit spring 385 can be pushed to shrink by pressing the push plate 387. After the limit spring 385 shrinks, the plug plate 386 is pulled out from the limit frame 383. After the plug plate 386 is pulled out from the inside of the limit frame 383, the hinge frame 382 inside the hinge slot 37 can be flipped, thereby causing the hinge frame 382 to be moved. 82 is in a vertical state, at which time the slider can be pulled out from the inner side of the slide slot 32, so that the filter screen 34 can be flexibly disassembled and assembled. When the filter screen 34 needs to be installed, it is only necessary to reinsert the sliders 33 at both ends of the filter screen 34 into the interior of the slide slot 32, and by turning over the hinged frame 382, ​​the hinged frames 382 are butted against each other. At this time, the limit spring 385 inside the sleeve frame 384 is reset and inserted into the interior of the limit frame 383. The plug plate 386 and the limit frame 383 are mutually limited, so that the base plate 36 and the sealing plate 35 at the top of the gas can be auxiliaryly clamped and installed, so that the filter screen 34 can be quickly disassembled and assembled, and the whole is easy to inspect and maintain.

[0033] By setting up the buffer mechanism 2, during the use of the device, the mounting ring 21 can be installed on the two ends of the acid-resistant pump body 1 by bolts, and then the entire device can be installed to the desired position by using the mounting plate and the bolts. During the use of the acid-resistant pump body 1, the buffer spring 23 can assist in buffering and shock absorption, which can improve the buffering and protection performance of the entire acid-resistant pump body 1. In addition, during its use, since the damper 25 is set, the damper 25 and the buffer spring 23 can assist in buffering and damping, which can reduce the overall amplitude of the buffer spring 23 and improve the overall stability of the device, so that the device as a whole can have strong anti-seismic performance during use, which can not only improve the anti-seismic performance of the acid-resistant pump body 1, but also reduce the noise during its operation, which can improve the overall ease of use of the device.
