Description

Technical Field

[0001] The utility model belongs to the technical field of electrostatic dust removal, in particular to a cleaning brush head for a dust collecting plate of an electrostatic dust collector. Background Art

[0002] Electrostatic precipitation is a method of gas dust removal. It works by first using the principle of ionizing electrode corona discharge to generate a high-voltage DC electric field, which ionizes gas molecules in the air, generating a large number of electrons and ions. This charges the dust particles in the surrounding dirty air. The charged dust-laden gas then passes through the dust collection assembly and is adsorbed by the dust collecting plates with opposite charges, achieving a dust collection effect and purifying the polluted air.

[0003] However, after a period of use, the thickness of dust accumulation on the dust collecting plate of the filter element increases, and the subsequent dust removal efficiency will be affected, and may even cause a series of safety problems such as sparks and electric creepage. Therefore, the dust collecting plate of the electrostatic dust collector needs to be manually cleaned and maintained regularly. At present, the industry mainly uses water washing as the cleaning method for high-voltage electrostatic dust collectors. After water washing, it is necessary to dry it or wait for it to be thoroughly dry before installing it for use, so as to avoid safety problems after turning on the power. This maintenance and cleaning process requires regular disassembly and operation in a professional and correct manner. It is more troublesome, and multiple disassembly and cleaning can easily damage the dust collecting device, resulting in increased maintenance costs. Some electrostatic dust removal products are also equipped with self-cleaning brushes, but the imperfect consideration of the scraping and dust collection process can easily cause secondary pollution. This application aims to study a dry cleaning device, optimize the dust cleaning mode, and in the process of cleaning the dust, simultaneously allow the dust to be closed and collected, which is conducive to the realization of integrated scraping and suction processing to avoid secondary pollution of the air.

[0028] Reference Figure 1-5 As shown, a cleaning brush head for a dust collecting plate of an electrostatic precipitator includes a cleaning plate 1 and a plurality of plate grooves 2 passing through the cleaning plate 1. Dust scrapers 3 are respectively provided on both sides of the plate grooves 2 and are inclined toward the center of the plate grooves 2. The dust scrapers 3 are provided on at least one side of the cleaning plate 1.

[0029] The dust removal plate passes through the plate groove 2 of the cleaning plate 1, and the scraper 3 is in contact with the surface of the dust removal plate at a certain tilt angle. When the cleaning plate 1 reciprocates, it scrapes and cleans the dust on the surface of the dust removal plate.

[0030] Furthermore, the inclination angle of the scraper blade 3 is 20°-30°.

[0031] At this angle, a better dust scraping effect can be achieved.

[0032] Furthermore, the inclination angle of the scraper blade 3 is 26.2°.

[0033] At this angle, a better scraping effect can be achieved, and wear is small, and deformation or damage of the scraping blade 3 is not likely to occur.

[0034] Furthermore, two sides of the plate groove 2 are respectively provided with "eight"-shaped slots (not shown), and the scraper blades 3 are arranged in the slots.

[0035] The scraper blade 3 is inserted into the slot and fixed by interference fit, a sealing strip 34 or glue. The "eight"-shaped slot allows the scraper blade 3 to be arranged at a certain angle to the dust removal plate.

[0036] Furthermore, a card slot 4 and a card strip 5 are respectively provided between the plate slots 2 . The outer end of the card slot 4 is V-shaped. The card strip 5 matches the shape of the card slot 4 . The scraper blade 3 is fixed in the card slot 4 through the card strip 5 .

[0037] The scraper blade 3 is fixed in the slot 4 by the clamping strip 5, and the outer end of the slot 4 is V-shaped, so that the scraper blade 3 and the dust removal plate are arranged at a certain angle. This structure is convenient for replacement and installation.

[0038] Furthermore, the scraping blade 3 is a PET film sheet, which has good scraping effect, low price, strong durability, and little damage to the dust removal plate.

[0039] Furthermore, a dust collecting plate 31 is provided at the upstream or downstream end of the scraping blade 3 , a dust collecting groove 32 is provided in the dust collecting plate 31 , and the scraping blade 3 extends into the dust collecting groove 32 ; the dust collecting groove 32 is provided with a dust collecting hole 33 .

[0040] The dust collecting plate 31 is fixed or integrally connected to the cleaning plate 1. By installing the dust collecting plate 31, when the cleaning plate 1 moves to one end of the electrostatic dust removal device, the cleaning plate 1 and the housing of the electrostatic dust removal device form a channel. The dust collection hole 33 is connected to the dust collector, and the other end is open. The side of the dust collecting plate 31 is sealed, and suction is generated in the channel, sucking dust on the scraper 3 into the dust collection groove 32. Upstream and downstream are relative to the air direction.

[0041] Furthermore, a sealing strip 34 is provided on the side of the dust collecting plate 31 .

[0042] The sealing strip 34 improves the sealing performance of the dust collecting plate 31 and forms a better dust collecting channel.

[0043] Furthermore, the cleaning plate 1 is provided with at least one piece.

[0044] Furthermore, the cleaning plate 1 is provided with two pieces, and moves relative to each other.

[0045] When two cleaning plates 1 are set, when they move relative to each other to the center, a dust suction channel is formed between the two cleaning plates 1; when the cleaning plates 1 move to both ends respectively, dust suction channels are formed with the shell of the dust removal device respectively, shortening the distance and time and improving the dust removal efficiency.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
