Technical Field

[0001] The invention relates to the technical field of dust filtration, in particular to a level II spiral filtration device of a wet dust collector. Background Art

[0002] At present, there are five types of dust removal methods on the market: bag filter, cyclone, dry mist, electrostatic and wet. The principle of wet dust removal is that the dust enters the inner cavity after being moistened by the water mist in the front section, and the mass increases and rotates at high speed. Under the action of centrifugal force, the dust-containing water mist is thrown to the wall of the dehydration cylinder to form a sewage flow, thereby achieving the purpose of dust removal.

[0003] However, the patents under the existing technology have the following disadvantages:

[0004] (1) The existing wet dust removal device lacks a structure that can evenly distribute the dust. The dust that enters the middle of the inner cavity of the dehydration cylinder cannot be separated from the air due to its low linear velocity and small centrifugal force, and is directly discharged from the outlet, resulting in the emission failing to meet indoor emission standards. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a type II spiral filter device for a wet dust collector which can increase the centrifugal force exerted on small particles in the airflow and has a higher dust removal efficiency.

DETAILED DESCRIPTION

[0025] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1:

[0028] like Figures 1 to 4 As shown, a II-stage spiral filter device of a wet dust collector includes: a device barrel 1, wherein flanges 2 are fixedly connected to the front and rear ends of the device barrel 1; a filter screen 3, wherein the filter screen 3 is fixedly connected to the inner side of the front end flange 2; an exhaust duct 4, wherein the exhaust duct 4 is fixedly connected to one side of the rear end flange 2; a suction assembly 5, wherein the suction assembly 5 is arranged on the inner side of the device barrel 1; a spiral assembly, wherein the spiral assembly is arranged on the rear side of the suction assembly 5; and a spray filter assembly 6, wherein the spray filter assembly 6 is arranged on the inner side of the device barrel 1.

[0029] The suction assembly 5 includes: a motor frame 501, a motor 502, a rotating shaft 503 and a fan blade 504. The motor frame 501 is fixedly connected to the front inner side of the device tube 1, the motor 502 is fixedly installed on the inner side of the motor frame 501, the rotating shaft 503 is fixedly connected to the end of the driving shaft at the front end of the motor 502, and the fan blade 504 is fixedly installed at the front end of the rotating shaft 503.

[0030] The spiral assembly includes: a rotating shaft 505 and a spiral piece 506, the rotating shaft 505 is fixedly connected to the end of the drive shaft at the rear end of the motor 502, and the spiral piece 506 is fixedly installed on the outer side of the rotating shaft 505.

[0031] The spray filtering assembly 6 includes: a diverter pipe 601, a spray pipe 602, a water filter cartridge 604 and a drain pipe 606. The diverter pipe 601 is fixedly connected to the bottom end of the inner rear part of the device cartridge 1. The bottom end of the diverter pipe 601 is connected to the external water supply system. The spray pipe 602 is fixedly connected to both ends of the diverter pipe 601. One side of the spray pipe 602 is fixedly connected to an atomizing nozzle 603. The water filter cartridge 604 is fixedly connected to the inner rear part of the device cartridge 1. The water filter cartridge 604 is conical with a larger front end and a smaller rear end. A baffle ring 605 is fixedly connected to the inner side of the front end of the water filter cartridge 604. The drain pipe 606 is fixedly connected to the bottom end of the device cartridge 1.

[0032] In specific use, the motor 502 is started to rotate the rotating shaft 503, and the rotating shaft 503 drives the fan blades 504 to rotate, sucking the external dust-containing gas into the device tube 1. The dust-containing gas is filtered by the filter 2 to remove larger particles, preventing the larger particles from colliding with the fan blades 504 and damaging the fan blades 504.

[0033] The water supply system connected to the shunt pipe 601 is started, and the clean water flows into the spray pipe 602 through the shunt pipe 601 and is sprayed out through the atomizing nozzle 603.

[0034] When the motor 502 drives the rotating shaft 1 503 to rotate, it also drives the rotating shaft 2 505 to rotate synchronously in the same direction. The rotating shaft 2 505 drives the outer spiral piece 506 to rotate. The spiral direction of the spiral piece 506 is consistent with the spiral direction of the fan blade 504, which increases the centrifugal force on the small particles at the center of the airflow, so that the small particles in the air can be moistened more evenly and are thrown onto the inner wall of the water filter cartridge 605 under the influence of the centrifugal force. The sewage flows into the bottom end of the device cartridge 1 through the leakage hole on the water filter cartridge and is discharged through the drain pipe 606, completing the air filtration. The clean air is discharged from the device cartridge 1 through the exhaust pipe 4.

[0035] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of the present disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
