Embodiment 1

[0044] This embodiment discloses a high-pressure water anti-pressure filtration method, using such as figure 1 The pressure-resistant filter device shown includes a filter device main body 1 , a fine filter assembly 2 , a high-voltage protection sleeve 3 , a first joint 5 , a second joint 6 and a cleaning switch 7 .

[0045] like figure 2As shown, the filter device main body 1 of this embodiment is an existing cylindrical filter cartridge structure, and the top of the filter device main body 1 is provided with a water inlet 11 integrally formed with it, and the water inlet 11 can also be directly welded by using existing welding techniques On the top of the filter device main body 1, and the inner wall of the water inlet 11 is provided with an internal thread;

[0046] The outer ring wall of the filter device main body 1 is provided with a plurality of water outlets 12 integrally formed with it, and the plurality of water outlets 12 can also be directly welded on the outer r...

Embodiment 2

[0062] The difference between this embodiment and the above-mentioned embodiment is that: figure 1 , Image 6 ,and Figure 7 As shown, this embodiment also includes a sealing ring 4 arranged between the first-stage filter screen pipe 21 and the high-pressure protection casing 3. The sealing ring 4 of this embodiment adopts an existing rubber sealing ring with a certain thickness. The sealing ring 4 is set on the lower end of the Class I filter screen pipe 21, and the inner hole wall of the sealing ring 4 is in interference fit with the outer ring wall of the lower end of the Class I filter screen pipe 21; And the inner wall of the lower port of the high-pressure protection sleeve 3 is in interference fit with the outer ring wall of the sealing ring 4;

[0063] The inner hole diameter of the sealing ring 4 is smaller than the inner hole diameter of the lower ring 2212, and the outer diameter of the sealing ring 4 is larger than the outer diameter of the lower ring 2212; the t...

Embodiment 3

[0066] The difference between this embodiment and the above-mentioned embodiment is that: Image 6 , Figure 7 As shown, the flow diverter 23 of this embodiment is a funnel-shaped structure with a large upper opening and a small lower opening.

[0067] By designing the diverter 23 as a funnel-shaped structure with a large upper opening and a smaller lower opening, it is ensured that the high-pressure fluid containing impurities is smoothly introduced into the first-stage filter screen 21 .

Abstract

The invention discloses a high-pressure water pressure-resistant filtering method, a pressure-resistant filtering device is used, the pressure-resistant filtering device comprises a filtering device main body, and a fine filtering assembly and a high-pressure protection sleeve which are sequentially arranged in the filtering device main body from inside to outside. An I-stage filter screen pipe isadditionally arranged, I-stage filtration of large-particle impurities is achieved through the I-stage filter screen pipe, II-stage fine filtration of small-particle impurities is achieved through the additionally-arranged cylindrical framework layer, meanwhile, the cylindrical framework layer plays a role in supporting and protecting the fine filter screen, the impact resistance of the fine filter screen is enhanced, and the stability and high efficiency of fluid filtration are improved; the high-pressure protective sleeve is additionally arranged, so that the fine filter screen cannot be deformed and damaged due to the action of high-pressure fluid, the impact force of the high-pressure fluid is reduced, and the fluid filtering stability is improved; meanwhile, the multiple water outlets are additionally formed, the one-inlet-multiple-outlet function of the filtering device is achieved, and therefore efficient and stable filtering of high-pressure fluid in the pipeline is achieved.

Description

technical field [0001] The invention relates to the technical field of fluid purification, in particular to a pressure-resistant filtration method for high-pressure water. Background technique [0002] At present, fluid pipeline transportation is widely used, and pipeline fluid impurity filtration has become an important topic in pipeline fluid transportation, especially when transporting fluid media in high-pressure, high-purity industrial application scenarios, it is necessary to add a filter device to filter impurities in the fluid. For example, the water pressure of high-pressure spray dust reduction in coal mines can be as high as 10MPa or more, and solid particles in the water often block the nozzle and affect the atomization effect. It can be seen that the stability of the filter device and the cleaning of filter impurities have a great impact on the filter effect. [0003] In the prior art, filter devices used for pipeline transportation of fluids are usually additi...
