Blockage-free elastic pressure relief component

Abstract

The invention relates to a blockage-free elastic pressure relief component. The blockage-free elastic pressure relief component comprises a bend pipe, a retaining plate is arranged in an inner cavity of the bend pipe, and the middle of the retaining plate is provided with a first water delivery hole extending along the thickness direction of the retaining plate and penetrating the retaining plate. A first mounting seat is arranged on the left side of the retaining plate, the middle of the first mounting seat is provided with a second water delivery hole extending along the thickness direction of the first mounting seat and penetrating the first mounting seat, and the second water delivery hole is communicated with the first water delivery hole. A spring is arranged on the left side of the first mounting seat, one end of the spring is arranged on the first mounting seat, and the other end of the spring is connected with a second mounting seat. The left end of the second water delivery hole is positioned in the center axis hole of the spring. The blockage-free elastic pressure relief component further comprises a pressure rod, the right end of the pressure rod penetrates the side wall of the bend pipe and is connected with the second mounting seat, and an input end of the pressure rod is connected with an output end of a driving device. By arrangement of the spring and the driving device, the blockage-free elastic pressure relief component is excellent in energy release effect and less prone to blockage in use.

Description

technical field [0001] The invention relates to a pressure release device, in particular to a non-clogging elastic pressure release assembly. Background technique [0002] The air flotation machine is a dissolved air system that produces a large number of fine bubbles in the water, so that the air attaches to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state of density lower than that of water. Liquid-separated water treatment equipment, in which the releaser is one of the components, is a device used to release the pressure of dissolved air water to adapt to subsequent treatment equipment. The low-pressure TJ type releaser used in conventional air flotation machines Developed in the 1980s, it is mainly used for pressure energy dissipation below 0.4MPA. It is a low-pressure releaser. Its main working principle is to use small holes and tiny gaps to eliminate the pressure in the sewage, so that the gas in the water body can The 10-50 ...

AI Technical Summary

Problems solved by technology

However, the existing low-pressure air flotation machine has a low dissolved air volume. In order to further increase the dissolved air volume of sewage and enhance the purification ability of sewage, it is necessary to develop a new type of high-pressure sewage treatment equipment with a working pressure of 0.5-0.8MPA. Due to its own structure, the existing low-pressure TJ type release device cannot eliminate such a high pressure, and the energy release effect is poor. Therefore, it is necessary to develop a new type of pressure relief assembly. In addition, the existing release device, due to its small The pores and gaps are used for energy dissipation, and the pores are easily blocked after long-term use, which affects its use effect
