AI Technical Summary
The existing pressure tank lacks a filtration device, resulting in poor water quality flowing through it and affecting overall working performance.
A filter screen is installed at the water inlet of the pressure tank, and a magnet and an adsorption cover are installed on the filter screen. The magnet adsorbs ferrous impurities in the water, and the filter screen can be quickly installed and removed by a snap-fit mechanism, which is convenient for cleaning.
It improves water quality, enhances the performance of the pressure tank, and facilitates the cleaning and maintenance of the filter screen.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pressure vessel technology, and relates to a pressure vessel, and particularly to a pressure vessel. Background Technology
[0002] A pressure tank is an instrument used to balance the volume and pressure of water.
[0003] The current pressure tank lacks a filter at the water inlet, resulting in poor water quality and poor overall performance of the pressure tank, affecting its use. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a pressure tank with a filtration structure.
[0005] The objective of this utility model can be achieved through the following technical solution: A pressure tank, comprising a pressure tank body having an inlet end and an outlet end, characterized in that a filter screen is provided on the inner wall of the inlet end, a connecting part is provided on the filter screen, an installation part for installing a filter assembly is provided on the inner wall of the inlet end, a connecting post is provided on the installation part, a connecting hole for the connecting post to pass through is provided on the connecting post, a snap-fit mechanism is symmetrically provided on the connecting post, an installation post is provided on the filter screen, a magnet is provided on the installation post, and an adsorption cover surrounding the magnet is detachably provided on the filter screen.
[0006] In the aforementioned pressure vessel, the connecting column has an open space for the locking mechanism to move, and the locking mechanism includes a locking block and a locking spring.
[0007] In one of the aforementioned pressure vessels, the magnet is fixed to the mounting post by a nut.
[0008] Compared with the prior art, this utility model can adsorb iron-containing impurities in the water by setting a filter screen and setting a magnet on the filter screen, and fix the impurities on the adsorption cover, thereby improving water quality and further improving working performance. The snap-fit mechanism set on the connecting column can realize quick disassembly and assembly of the filter screen and the pressure tank body, which facilitates the cleaning of the filter screen later.

[0010] Figure 2 This is a partially enlarged schematic diagram of point A of this utility model.
[0011] Figure 3 This is a partially enlarged schematic diagram of section B of this utility model.
[0012] In the diagram, 1 is the water inlet; 2 is the water outlet; 3 is the pressure tank body; 4 is the filter screen; 5 is the connection part; 6 is the mounting part; 7 is the connecting column; 8 is the connecting hole; 9 is the snap-fit mechanism; 10 is the mounting column; 11 is the magnet; 12 is the adsorption cover; 13 is the movement space; 14 is the snap-fit block; and 15 is the snap-fit spring. Detailed Implementation
[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0014] like Figure 1 , Figure 2 , Figure 3 As shown, this pressure tank includes a pressure tank body 3 with an inlet end 1 and an outlet end 2. A filter screen 4 is provided on the inner wall of the inlet end 1. A connecting part 5 is provided on the filter screen 4. An installation part 6 for installing a filter assembly is provided on the inner wall of the inlet end 1. A connecting post 7 is provided on the installation part 6. A connecting hole 8 for the connecting post 7 to pass through is provided on the connecting part 5. A snap-fit mechanism 9 is symmetrically provided on the connecting post 7. An installation post 10 is provided on the filter screen 4. A magnet 11 is provided on the installation post 10. An adsorption cover 12 surrounding the magnet 11 is detachably provided on the filter screen 4.
[0015] To elaborate further, the connecting column 7 has an active space 13 for the locking mechanism 9 to move. The locking mechanism 9 includes a locking block 14 and a locking spring 15.
[0016] To elaborate further, the magnet 11 is fixed to the mounting post 10 by a nut.
[0017] Working principle: When cleaning the filter screen 4 later, press the locking block 14 into the movable space 13 to let the locking mechanism 9 lose its constraint on the filter screen 4, then take out the filter screen 4, and then rotate the adsorption cover 12 to remove the adsorption cover 12. The iron-containing impurities that were originally adsorbed on the adsorption cover 12 lose the attraction of the magnet 11 and can be easily cleaned by rinsing with clean water, which improves water quality and further improves working performance.
[0018] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0019] Although this document frequently uses terms such as inlet end 1, outlet end 2, pressure tank body 3, filter screen 4, connecting part 5, mounting part 6, connecting column 7, connecting hole 8, snap-fit mechanism 9, mounting column 10, magnet 11, adsorption cover 12, moving space 13, snap-fit block 14, and snap-fit spring 15, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
