Technical Field

[0001] The utility model relates to the technical field of desander filter screens, in particular to a pneumatic jacking device for a desander filter screen. Background Art

[0002] A desander is a device that separates particles from air, water, or wastewater streams. The desander's principle is based on the effects of pressure and buoyancy. A mixture of sand and gravel enters the desander through an inlet and is fed into a rotating cylinder. The cylinder is equipped with spiral blades, which separate impurities deposited on the sand and gravel from the sand and gravel. Once the sand and gravel mixture enters the desander, the rotating cylinder forces the sand and gravel to form a rotating fluid layer within the cylinder. In this rotating fluid layer, centrifugal force forces heavy sand and gravel particles outward, while lighter impurities are adsorbed on the cylinder's walls and discharged through the outlet. After a period of use, the desander's internal filter screen needs to be replaced.

[0003] In the prior art, replacing the filter screen inside a desander requires installing bearings, lifting the filter screen via the bearings, and designing a crossbeam, making the operation relatively complicated. Therefore, those skilled in the art have provided a pneumatic lifting device for a desander filter screen to address the problems raised in the background art. Utility Model Content

When in use, the device hooks the filter screen through a hook, and then drives the hook to move upward through an air lifting chain, thereby lifting the filter screen. The filter screen can be lifted to a height of 2 meters, which is conducive to quickly and conveniently removing the filter screen without installing bearings or beams.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a pneumatic lifting device for a sand remover filter screen, comprising a metal sand screen, two fixing rings of a sand filter frame and four bolts, characterized in that: the two fixing rings are fixed to the upper end of one side of the sand filter frame by four bolts, a fixing plate is fixed to the lower end of one side of the sand filter frame, a cylinder is fixed inside the two fixing rings, an iron chain is fixed on one side of the output end of the cylinder, and a hook is fixed at the lower end of the iron chain.

[0006] Furthermore, a filter body is provided at the inner upper end of the sand filter frame, and the hook is connected to the upper end of the filter body.

[0007] Furthermore, a water inlet pipe is fixedly provided on the side of the lower end of the sand filter frame close to the metal sand screen, and a water outlet pipe is fixedly provided on the side of the lower end of the sand filter frame away from the metal sand screen.

[0008] Furthermore, a gate valve assembly is fixedly provided in the middle of the lower end of the inner part of the sand filter frame, and a sand discharge pipeline is connected between the gate valve assembly and the metal sand screen.

[0009] Furthermore, a pressure relief pipe is fixedly provided on the side of the lower end of the sand filter frame away from the metal sand screen, and a control panel is fixedly provided on the side of the lower end of the sand filter frame close to the metal sand screen.

[0010] Furthermore, a double pot is fixedly provided at the upper end of the inner part of the sand filter frame.

[0011] The utility model has the following beneficial effects:

[0012] The utility model provides a pneumatic lifting device for the desander filter. When the device is in use, the filter body is hooked by a hook, and then the cylinder is started. The cylinder pushes the iron chain and the hook to move upward, and then the filter body is lifted out, which makes it easy to replace the filter body, does not require the installation of bearings or beams, and simplifies the operation.
