Description

Technical Field

[0001] The utility model relates to the technical field of filtering and dust removal, in particular to a cartridge dust collector with a high-efficiency dust discharge mechanism. Background Art

[0002] In recent years, with the continuous development of new technologies and new materials, represented by companies in Japan and the United States, improvements have been made to the structure and filter materials of dust collectors, making cartridge dust collectors widely used in cement, steel, electricity, food, metallurgy, chemical and other industrial fields. The overall capacity has increased several times, becoming a large dust collector with a filtration area of >2000m2. It is the best solution to solve the problems of traditional dust collectors in collecting ultrafine dust, high filtration wind speed, poor cleaning effect, easy wear and leakage of filter bags, and high operating costs. Compared with various bag-type and electrostatic dust collectors on the market, it has the characteristics of large effective filtration area, low pressure difference, low emissions, small size, and long service life, becoming a new direction for the development of industrial dust collectors.

[0003] After a period of use, dust accumulates on the outer walls of existing cartridge dust collectors, necessitating dust removal. Currently, a pulse valve is used to inject high-pressure air into the upper opening of the cartridge, rapidly separating the dust. However, this separation method is limited in effectiveness, as a certain amount of dust still accumulates on the outer surface of the cartridge, resulting in incomplete removal. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the current separation method has limited effect, and a certain amount of dust will accumulate on the outside of the filter cartridge, resulting in incomplete removal.

[0006] A top sinking hole for installing a top rebound component is provided at the upper opening of the circular assembly hole.

[0007] The top rebound component includes a top assembly cover fixed on the upper end of the outer side of the air filter cartridge, an annular sealing cover fixed inside the top sinking hole, and a return spring installed between the top assembly cover and the annular sealing cover.

[0008] An upper air guide port is provided at the upper end of the horizontal blowing pipe corresponding to the exhaust hole at the upper end of the clean air chamber, and a lower air jet port is provided at the lower end of the horizontal blowing pipe corresponding to the air filter cartridge.

The intermittent regulating pipe includes an annular assembly frame slidably assembled with the lateral limit frames on both sides and an arc-shaped closing plate staggered and fixed on the inner side of the annular assembly frame.

[0010] An external regulating motor is fixedly mounted on the outer side surface of the dust collector hopper box at the upper end of the horizontal blowing pipe, and an internal transmission component for transmitting and connecting the external regulating motor and the intermittent regulating pipe is installed on the inner top surface of the horizontal blowing pipe.

[0011] The beneficial effects of the utility model are:

[0012] (1) The utility model is a cartridge dust collector with a high-efficiency dust removal mechanism. The air filter cartridge is installed inside a horizontal assembly plate by adopting an elastic assembly method. High-pressure air is sprayed downward through a horizontal blowing pipe to control the vibration of the air filter cartridge, thereby improving the separation effect of surface dust.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0020] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The shown embodiment shows a cartridge dust collector with a high-efficiency dust discharge mechanism, comprising a dust collector hopper body 1 and an air filter cartridge 2. A dust discharge valve for discharging dust is installed at the lower end of the dust collector hopper body 1. The interior of the dust collector hopper body 1 is divided into a dirty air chamber and a clean air chamber by a horizontal assembly plate 3. A horizontal blow pipe 4 is fixedly installed above the horizontal assembly plate 3 inside the dust collector hopper body 1. A circular assembly hole 5 for installing the air filter cartridge 2 is provided inside the horizontal assembly plate 4. The upper end opening of the circular assembly hole 5 is located at the position of the air filter cartridge 2 and a top rebound component 6 is installed thereon. An intermittent control pipe 7 is movably installed inside the horizontal blow pipe 4.

[0022] Working principle: The horizontal blowing pipe 4 introduces continuous external air from the outside into the clean air chamber, and then uses the intermittent control pipe 7 to spray the air upward and downward at intervals. When the air is sprayed upward, the air in the dirty air chamber can be quickly filtered and drawn into the clean air chamber, and then discharged to the outside; when the air is sprayed downward, the dust on the outside of the air filter cartridge 2 is discharged into the dirty air chamber, and the air filter cartridge 2 vibrates through the top rebound component 6 to improve the dust removal effect. Finally, the dust accumulates at the bottom and is finally discharged through the dust discharge valve 3.

[0023] In order to cooperate with the top assembly, a top sinking hole for installing the top rebound component 6 is opened at the upper opening position of the circular assembly hole 5.

[0024] In order to cooperate with elastic assembly and reset lifting, the top rebound component 6 includes a top assembly cover 61 fixed to the upper end of the outer side of the air filter cartridge 2, an annular sealing cover 62 fixed inside the top sinking hole, and a reset spring 63 installed between the top assembly cover 61 and the annular sealing cover 62.

[0025] In order to facilitate exhaust, an upper air guide port 41 is opened at the upper end of the horizontal blowing pipe 4 corresponding to the exhaust hole at the upper end of the clean air chamber, and a lower air injection port 42 is opened at the lower end of the horizontal blowing pipe 4 corresponding to the position of the air filter cartridge 2.

[0026] In order to cooperate with assembly and rotation adjustment, the inner side surface of the horizontal blowing pipe 4 is provided with lateral limit frames 43 on both sides of the intermittent regulating pipe 7. The intermittent regulating pipe 7 includes an annular assembly frame 71 that is slidably assembled with the lateral limit frames 43 on both sides and an arc-shaped closing plate 72 that is offset and fixed on the inner side of the annular assembly frame 71.

[0027] In order to cooperate with the rotation control, an external adjustment motor 8 is fixedly installed on the outer side of the dust collector hopper box 1 at the upper end of the horizontal blowing pipe 4, and an internal transmission component 9 for transmitting and connecting the external adjustment motor 8 and the intermittent control pipe 7 is installed on the inner top surface of the horizontal blowing pipe 4.

[0028] The internal transmission assembly 9 includes a horizontal rotating shaft movably mounted inside the horizontal blowing pipe 4 through a bracket on the inner top surface of the horizontal blowing pipe 4, lateral transmission gears axially fixed on both sides of the horizontal rotating shaft, and a control gear axially fixed on the drive shaft at the lower end of the external adjustment motor 8. The external adjustment motor 8 is meshed with the lateral transmission gear on one section of the horizontal rotating shaft through the control gear at the lower end, and the lateral transmission gear on the other side of the horizontal rotating shaft is meshed with the annular tooth surface on the annular assembly frame 71. When the external adjustment motor 8 is running, it synchronously drives the annular assembly frame 71 to rotate. The annular assembly frame 71 then synchronously drives the internal arc-shaped closing plate 72 to control the intermittent opening and closing of the upper air guide port 41 and the lower air jet port 42. The length of the arc-shaped closing plate corresponding to the position of the upper air guide port 41 is greater than the length of the arc-shaped closing plate corresponding to the position of the lower air jet port 42. When the upper air guide port 41 is about to close and the lower air jet port 42 is about to open, the two arc-shaped closing plates at this position will overlap, and their function is to pressurize the inside of the horizontal blow pipe 4, thereby increasing the pressure of the lower air jet port 42 when it is opened, and improving the effect of jetting to remove dust.

[0029] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
