Problems solved by technology

[0002] The current filtering device or purification equipment has a disadvantage, that is, only the filtered fluid can be discharged, and the filtered dirt can only stay inside the filter assembly. If you want to clean it, you can only disassemble the filter assembly. Then clean the filter element or replace the filter element; in addition, the filtration efficiency of most filter devices is not high. affect the filtration efficiency

Embodiment 1

[0021] Such as figure 1 , 2 A kind of double variable-diameter screw-type filtering device shown, comprises filter cartridge 1 and motor 2, and the output shaft of described motor 2 is connected with booster screw 3, and booster screw 3 is positioned in filter cartridge 1, and the booster screw 3 The axis is parallel to the axis of the filter cartridge 1; one or more sections of positive pressurization section 4 are arranged on the booster screw 3, each positive pressurization section 4 has at least two fluid pressurization zones, and at the end The tail end of a booster zone is provided with a reverse booster section 5; the positive booster section 4 is opposite to the reverse booster section 5 in the direction of fluid delivery; in the filter cartridge near the first positive booster section 4 1. A fluid inlet 10 is provided on the end of the wall surface, and a sewage outlet 11 is provided on the wall end of the filter cartridge 1 close to the anti-pressurization section ...

Embodiment approach

[0032] Specifically, such as image 3 , 4 As shown, the positive pressurization section 4B includes a threaded disc one 41B and a threaded disc two 42B, and the anti-boosting section includes a threaded disc three 50B; The radial wall surface of 50B is provided with a number of uniformly distributed spiral blades 7B, and the spiral blades 40B are all fixed on the booster screw 3B; The spiral direction of 7B is opposite, and the spiral blade 7B of threaded disk three 50B is facing the spiral blade 7B of threaded disk two 42B.

[0033] More specifically, the helical direction of the helical blade 7B on the first threaded disc 41B is the same as the helical direction of the helical blade 7B on the second threaded disc 42B, and the helical blade 7B on the second threaded disc 42B extends along the extension length C of the booster screw 3 It is longer than the extension length C of the helical blade 7B on the threaded disc 1 41B along the booster screw 3B.

Abstract

The invention relates to a double reducing screw type filtering device which comprises a filter cartridge and a motor, wherein a supercharging screw rod is connected with an output shaft of the motor;the supercharging screw rod is located in the filter cartridge; the axis of the supercharging screw rod is parallel to the axis of the filter cartridge; one or more than one positive supercharging section is arranged on the supercharging screw rod; at least two fluid supercharging areas are arranged in each positive supercharging section; a negative supercharging section is arranged at the tail end of the last fluid supercharging area; the positive supercharging section and the negative supercharging section have opposite directions for conveying the fluid. Compared with the prior art, the double reducing screw type filtering device provided by the invention has the advantages of filtering efficiency at least increased by above 5 times, excellent filtering effect, self-cleaning function and no requirement for replacing filter elements.

Description

technical field [0001] The invention relates to the field of fluid purification equipment, in particular to a double variable-diameter screw filter device. Background technique [0002] The current filtering device or purification equipment has a disadvantage, that is, only the filtered fluid can be discharged, and the filtered dirt can only stay inside the filter assembly. If you want to clean it, you can only disassemble the filter assembly. Then clean the filter element or replace the filter element; in addition, the filtration efficiency of most filter devices is not high. affect the filtration efficiency. Contents of the invention [0003] In order to overcome the above problems, the present invention provides a double variable-diameter screw filter device with high filtration efficiency and no need to replace the filter assembly. [0004] To achieve the above object, the technical solution provided by the invention is: [0005] A double variable-diameter screw fil...
