Description

Technical Field

[0001] The utility model relates to the technical field of air springs, in particular to a hammering air spring for a perlite filter. Background Technique

[0002] The perlite filter captures particles on the surface of a hose coated with perlite medium. When the particulate matter intercepted by the perlite filter media increases to a certain extent, the regenerative media filter "hits" to shed the filter media from the surface of the filter tube, and then automatically enters the precoating process. An air spring is filled with compressed air in a sealed container, and its elastic effect is realized by the compressibility of the gas. The air spring has an ideal non-linear elastic characteristic. The working principle is to fill an inert gas or an oil-gas mixture in a sealed pressure cylinder, so that the pressure in the cavity is several times or dozens of times higher than the atmospheric pressure, and the movement of the piston rod is realized by using the pressure difference generated by the cross-sectional area of the piston rod being smaller than that of the piston. Due to the fundamental difference in principle, the air spring has significant advantages over ordinary springs: relatively slow speed, small change in dynamic force (generally within 1:1.2), and easy to control.

[0003] However, during the use of the existing perlite filter, the manual static natural shedding process cannot quickly shed the perlite filter media from the filter tube, affecting the filtering effect. Therefore, those skilled in the art have provided a hammering air spring for a perlite filter to solve the problems raised in the above background technique. Content of the Utility Model

[0007] As a further solution of the present invention: A support column is fixed outside the fixed connecting plate, and a fixed half-threaded column is fixed outside the support column. A limit shielding plate is fixed at one end of the fixed half-threaded column.

[0008] As a further solution of the present invention: A movable half-threaded column is fixed outside the rotating connecting frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-3, the present utility model provides a hammering air spring for a perlite filter, which includes a perlite filter pipe fixing sieve plate 1. The top of the perlite filter pipe fixing sieve plate 1 is connected with a perlite filter pipe fixing pressing plate 2. The top of the perlite filter pipe fixing pressing plate 2 is installed with a sieve plate pressing plate sealing gasket 3. The top of the sieve plate pressing plate sealing gasket 3 is fixed with a pressing plate sieve plate sealing plate 4. The top of the pressing plate sieve plate sealing plate 4 is fitted with a sieve plate vertical sealing plate 5. The top of the sieve plate vertical sealing plate 5 is connected with a hammering air spring envelope 6. Inside the hammering air spring envelope 6 is provided with a hammering bushing sealing ring 7. Outside the hammering air spring envelope 6 is installed a reinforcement device 8. Inside the hammering air spring envelope 6 is provided with a central shaft main body 9 extending to the outside. Outside the central shaft main body 9 is provided with a sealing ring main body 10. Outside the central shaft main body 9 is fitted with a central shaft fixing nut 11. Outside the central shaft main body 9 is provided with a hammering air spring main body 12. The top of the sieve plate vertical sealing plate 5 is connected with a perlite filter water outlet flange 13.

[0023] During the use of this device, after the hammering air spring main body 12 quickly exhausts air, it generates disturbance with water. During the instant rapid lifting process, it forms an opposite direction with the water flow and uses the reverse force to achieve the shedding of the perlite filter material on the filter pipe. After 6 - 8 times of repeated hammering vibrations, the filter material, solid pollutants, etc. on the surface of the filter pipe will all fall off from the filter pipe, achieving a function of quickly separating the filter material. When the hammering air spring main body 12 is in the perlite filtering state, it is in a lifted state. Using compressed air as kinetic energy, the perlite filter pipe fixing sieve plate 1 that fixes the filter pipe inside the perlite filter is always in a lifted state. After the perlite filter pipe fixing sieve plate 1 is lifted, a combination is formed between it and the vertical plate. The perlite filter pipe fixing sieve plate 1 is made of a 6mm stainless steel plate and is arranged in a uniform distribution on the sieve plate to prevent deformation problems caused by the long-term force on the too large sieve plate diameter. At the connection between the hammering air spring main body 12 and the central shaft main body 9, there is a sealing ring main body 10, which can prevent air leakage or water leakage from damaging the equipment. The top of the central shaft main body 9 and the air spring fixing position are fixed with nuts. The lower half of the central shaft main body 9 and the perlite filter pipe fixing sieve plate 1 are connected by a flange and fixed with screws. In this way, there is an effective hammering space that can move up and down between the hammering air spring main body 12 and the perlite filter pipe fixing sieve plate 1.
