Description

Technical Field

[0001] The utility model relates to a backwash cleaning device. Background Art

[0002] In order to ensure the efficiency of the air handling system, a primary filter dust collector with filtering as the main function will be installed at the fresh air inlet of the air conditioning system. At the fresh air inlet of some ventilation systems, in order to ensure the quality of air entering the ventilation space, a primary filter dust collector will also be installed at the air inlet. These primary filter dust collectors (especially those installed in some places that work all year round: such as power distribution rooms, elevator rooms, data rooms, precision processing workshops, etc.) will increase the amount of dust accumulated in the filter dust collector as the use time increases, which will increase the resistance of the air inlet and reduce the filtering efficiency. The traditional practice is to replace the filter dust collector. However, in some special installation locations and places, the difficulty and frequency of cleaning the primary filter dust collector or replacing the primary filter dust collector will greatly affect the operating effect of the subsequent system protected by the primary filter dust collector. In order to solve the problem of cleaning and replacing the filter, designing a backwash cleaning structure that is conducive to cleaning the primary dust collector is the research direction of the utility model.

Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0032] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] Reference Figure 1-5 As shown, a backwash cleaning device includes

[0034] The device body 1 and a plurality of frames 10 are arranged around the device body 1 .

[0035] The dust collecting component 2 is connected to the air inlet 300 and the air outlet 300 - 0 and is used for absorbing and removing dust.

[0036] Among them, the dust collection component 2 (back-blowing device) is not limited to the device used in conjunction with it. The device body 1 in this case is only a simple schematic diagram, and the device connected to the dust collection component 2 is not limited here and can be set according to actual needs.

[0037] The dust collecting assembly 2 includes: an outer shell 200, a deflector 21 arranged at one end of the outer shell 200; an inner shell 22 arranged inside the outer shell 20, a dust collecting shell 23 extending to the outside is mounted in the middle of the inner shell 22, a filter screen 28 is arranged on the inner circle of the dust collecting shell 23, a dust collecting fan 211 connected to the motor 29, and a first cleaning member 25 and a second cleaning member 26 clamped on the dust collecting shell 23. The first cleaning member 25 and the second cleaning member 26 rotate synchronously with the dust collecting fan 211 through the connecting shaft 210, so that the first cleaning member 25 and the second cleaning member 26 clean the dust on the filter screen 28, thereby discharging the dust through the dust collecting fan 211.

[0038] The shape of the outer shell 20 is not limited, and can be cylindrical, rectangular or square, etc. In this case, for the sake of product aesthetics, a cylindrical shape is preferred. The specific implementation can be set according to actual needs.

[0039] The outer edge of the deflector 21 is provided with a circle of enclosure 21-0. Wherein, the enclosure 21-0 can discharge rainwater along its edge in rainy weather to prevent rainwater from entering the inner shell 22.

[0040] It should be noted that the first cleaning member 25 and the second cleaning member 26 in this case are also equipped with a transmission (not shown in the figure, and the transmission is a prior art, so no further details are given here), so that the rotation speed of the first cleaning member 25 and the second cleaning member 26 can be controlled.

[0041] An intermediate sleeve 220 is provided in the middle of the inner shell 22. The intermediate sleeve 220 is connected to the inner shell 22 via a connecting partition 222. The connecting partition 222 divides the inner shell 22 into three spaces of equal size to reduce mutual interference between components and improve the stability of equipment operation.

[0042] Furthermore, the three spaces of equal size separated by the connecting partition 222 can be used to install a specific function or store specific components, which helps to keep the equipment tidy and orderly (such as sensors or transducers, etc., which are added according to specific needs and will not be elaborated here). Moreover, the connecting partition 222 can make more efficient use of the internal space and optimize the layout of the components, making it easier to maintain or replace specific components because each component is individually isolated. At the same time, if some components generate more heat, the separation design helps to control the heat distribution and prevent local overheating. It can also serve as a barrier to vibration and noise, reducing their propagation inside the equipment. In some cases, the connecting partition 222 can provide additional safety protection, for example, preventing electrical components from coming into contact with other components that may generate sparks.

[0043] The opening of the air deflector 21 is semicircular or straight. In one embodiment, the opening of the air deflector 21 is semicircular, and the semicircular opening is inclined. The advantage of this arrangement is that it helps to guide the airflow to flow in a specific direction, reduce the formation of turbulence and eddies, and thus reduce the rebound and deposition of dust in the pipe. Among them, the semicircular opening inclined upward has an inclination angle B, and B is greater than or equal to 25 degrees or less than or equal to 40 degrees. Preferably, the inclination angle B is about 38 degrees. The advantage of this arrangement is that the airflow direction can be optimized, the efficiency of dust transportation can be improved, and the smooth discharge of dust can be ensured.

[0044] Furthermore, the upwardly inclined semicircular opening discharges the airflow in an orderly manner. The orderly airflow can reduce the wear of the inner wall of the pipe and extend the service life of the pipe; the semicircular air deflector can reduce the turbulence of the airflow in the pipe, thereby reducing the noise level; it helps to concentrate the discharge direction of dust and reduce the spread of dust to the surrounding environment; the orderly airflow makes it easier for dust to settle in a specific area, which is convenient for regular cleaning and maintenance.

[0045] The first cleaning member 25 and the second cleaning member 26 both include flexible scraping strips or bristles. The flexible scraping strips are wear-resistant and corrosion-resistant, and their sharp inner angles are between 2 degrees and 60 degrees. In one embodiment, in order to improve the dust removal effect, the sharp inner angle is about 7 degrees; and the bristle material is not easy to condense due to oil, so the scraper can be used while brushing, further improving the cleaning effect.

[0046] The distance between the first cleaning member 25 and the second cleaning member 26 is smaller than the aperture of the filter 28, thereby ensuring that dust can be effectively removed.

[0047] The first cleaning member 25 and the second cleaning member 26 are arranged in a cross-type. The cross-arranged brushes can increase the contact area with the filter 28, thereby removing dust more effectively; cleaning from different angles can reach different parts of the filter 28, especially those hard-to-reach corners and gaps; the cross-brush can clean the filter 28 from two directions at the same time, improving the cleaning speed and efficiency; the cross-brush can disperse the pressure on the filter 28 during cleaning and reduce the damage to the filter 28; the cross-brush may produce more adsorption, which helps to absorb finer dust particles from the surface of the filter 28; the cross-arrangement helps to distribute the cleaning force more evenly, avoiding local excessive cleaning and damage to the filter 28.

[0048] Furthermore, the distance between the first cleaning member 25 and the second cleaning member 26 varies according to the change of the aperture of the filter 28, and is specifically implemented according to actual needs.

[0049] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
