Description

Technical Field

[0001] The utility model relates to the field of dust collection, in particular to a dust collection device in an electrostatic dust removal device. Background Technique

[0002] Electrostatic dust removal is a method of gas dust removal. When the dusty gas passes through a high-voltage electrostatic field, it is electrically separated. After the dust particles combine with negative ions and carry negative charges, they tend to discharge on the anode surface and deposit. It is used in metallurgy, chemistry and other industries to purify gases or recover useful dust particles. A dust collection method that uses an electrostatic field to ionize a gas so that dust particles are charged and adsorbed onto an electrode. In a strong electric field, air molecules are ionized into positive ions and electrons. When the electrons run towards the positive electrode, they encounter dust particles, making the dust particles carry negative charges and be adsorbed onto the positive electrode and collected.

[0003] Chinese Patent No. CN202222072360.5 discloses a dust collection device in a high-voltage electrostatic dust removal device, including a high-voltage electrostatic dust remover. A support frame is fixedly connected to the surface of the high-voltage electrostatic dust remover. A base is fixedly connected to the bottom of the support frame. A placement groove is formed on the surface of the base. A collection box is placed inside the placement groove. A top cover is installed on the surface of the collection box. A fixed pipe is fixedly connected and communicated with the surface of the top cover. An extension pipe is slidably connected inside the fixed pipe. A discharge pipe is fixedly connected and communicated with the bottom of the high-voltage electrostatic dust remover. The top end of the extension pipe is sleeved on the surface of the discharge pipe. Sealing components are provided at opposite ends of the discharge pipe and the extension pipe. An elastic component is provided inside the fixed pipe.

[0004] As can be seen from the above, by pushing the extension pipe to slide on the surface of the discharge pipe through the elastic component, after the high-voltage electrostatic dust remover removes dust, the dust can be shaken off the two-pole system by the vibration device inside the equipment and discharged into the collection box through the discharge pipe. The sealing component can seal the connection between the discharge pipe and the extension pipe. However, this case still has the following deficiencies: When electrostatic dust removal collects dust, it mainly relies on the self-weight of the dust to fall, so that the dust falls into the ash hopper. When the dust in the ash hopper is exported, the prior art cannot control the flow rate of the falling dust during dust collection, resulting in too large a dust flow rate and flying everywhere during collection.

[0005] Therefore, a dust collection device in an electrostatic dust removal device is proposed for the above problems. Summary of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve the problem of not being able to control the dust falling flow rate, the utility model proposes a dust collection device in an electrostatic dust removal device.

[0007] The technical solution adopted by the present utility model to solve its technical problems is as follows: A dust collection device in an electrostatic dust removal device of the present utility model includes a main body and a cleaning and collection assembly; a collection hopper is installed on the cleaning and collection assembly. A groove is formed at the bottom of the collection hopper, and a control chamber is fixedly installed. A movable shaft is movably installed on one side of the control chamber. An installation plate is fixedly installed at the bottom of the movable shaft, and a servo motor is fixedly installed on the top of the installation plate.

[0008] Preferably, a fixed frame is installed on the main body. An adsorption chamber is fixedly installed on the top of the fixed frame. A centrifugal fan is fixedly installed on one side of the adsorption chamber. A cleaning box is placed on the top of the fixed frame.

[0009] Preferably, two anode plates are fixedly installed in the inner cavity of the adsorption chamber. A cathode plate is fixedly installed in the inner cavity of the adsorption chamber. A groove is formed at the bottom of the adsorption chamber, and the collection hopper is fixedly installed through the groove.

[0010] Preferably, a ball screw is fixedly installed at the output end of the servo motor. The ball screw penetrates and is threadedly connected to a ball nut. A linkage arm is hinged to one side of the ball nut, and a rotating shaft is fixedly installed at the other end of the linkage arm.

[0011] Preferably, both ends of the rotating shaft penetrate and are movably installed with fixed bearings. One side of the two fixed bearings is fixedly installed with a control chamber. A movable baffle is fixedly installed on one side of the rotating shaft. The movable baffle is installed in the inner cavity of the control chamber.

[0012] Preferably, two limit bearings are fixedly installed on the top of the installation plate. The two limit bearings penetrate and are movably installed with the ball screw.

[0013] The beneficial effects of the present utility model are as follows:

[0014] Through the structural design of the cleaning and collection assembly of the present utility model, the servo motor is driven to make the ball screw at the output end perform a rotational motion. When the ball screw performs a rotational motion, it is in threaded cooperation with the ball nut. Under mutual linkage, the ball nut drives the rotating shaft to rotate through the linkage arm. The rotating shaft drives the movable baffle to move in the inner cavity of the control chamber, causing a gap to be generated in the inner cavity of the control chamber. Dust falls through the gap between the control chamber and the movable baffle, realizing the function of controlling the movement, solving the problem of being unable to control the dust falling flow rate, and improving the adaptability in use.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figures 1 - 5 As shown, a dust collection device in an electrostatic dust removal device includes a main body 1 and a cleaning and collection component 2; a collection hopper 21 is installed on the cleaning and collection component 2. A groove is opened at the bottom of the collection hopper 21, and a control bin 22 is fixedly installed. A moving shaft 23 is movably installed on one side of the control bin 22. The bottom of the moving shaft 23 is fixedly installed with a mounting plate 24, and a servo motor 25 is fixedly installed on the top of the mounting plate 24;

[0024] During operation, the installation of the collection hopper 21 facilitates the collection of the falling dust. The opening of the groove in the collection hopper 21 is conducive to the transportation of the collected dust, and the movable installation of the movable shaft 23 by the control bin 22 prevents movement interference during the operation of the servo motor 25.

[0025] Furthermore, the main body 1 is equipped with a fixed frame 11. At the top of the fixed frame 11, an adsorption bin 12 is fixedly installed. On one side of the adsorption bin 12, a centrifugal fan 13 is fixedly installed. At the top of the fixed frame 11, a cleaning box 34 is placed.

[0026] During operation, the fixed frame 11 supports the whole, which is conducive to ensuring the stable operation of the whole. The cleaning box 34 collects the guided dust, facilitating the transportation and cleaning by personnel.

[0027] Furthermore, two anode plates 14 are fixedly installed in the inner cavity of the adsorption bin 12. A cathode plate 15 is fixedly installed in the inner cavity of the adsorption bin 12. A groove is opened at the bottom of the adsorption bin 12, and a collection hopper 21 is fixedly installed through the groove.

[0028] During operation, the air entering the inner cavity of the adsorption bin 12 is filtered and adsorbed through the cooperation of the anode plate 14 and the cathode plate 15, and the dust in the air is adsorbed on the anode plate 14.

[0029] Furthermore, a ball screw 26 is fixedly installed at the output end of the servo motor 25. The ball screw 26 penetrates and is threadedly connected to a ball nut 28. One side of the ball nut 28 is hinged with a linkage arm 29, and the other end of the linkage arm 29 is fixedly installed with a rotating shaft 31.

[0030] During operation, the ball nut 28 cooperates with the linkage arm 29 through the thread. During the movement, the linkage arm 29 makes a circular movement with the rotating shaft 31 as the axis, and the movable shaft 23 makes a circular movement with the connection part of the control bin 22 as the axis, which is conducive to realizing the rotation of the rotating shaft 31.

[0031] Furthermore, both ends of the rotating shaft 31 penetrate and are movably installed with fixed bearings 32. On one side of the two fixed bearings 32, a control bin 22 is fixedly installed. On one side of the rotating shaft 31, a movable baffle 33 is fixedly installed, and the movable baffle 33 is installed in the inner cavity of the control bin 22.

[0032] During operation, when the rotating shaft 31 rotates, it drives the movable baffle 33. During the movement of the movable baffle 33, a gap is generated in the inner cavity of the control bin 22, and the flow rate of the falling dust is controlled by the size of the gap.

[0033] Furthermore, two limit bearings 27 are fixedly installed at the top of the mounting plate 24. The two limit bearings 27 penetrate and are movably installed with the ball screw 26.

[0034] During operation, the ball screw 26 is supported by the installation of the limit bearing 27, while ensuring that it can perform corresponding rotational motion.

[0035] Working principle: Step 1, guide the air through the driving centrifugal fan 13, so that the dusty air enters the inner cavity of the adsorption chamber 12. At this time, the anode electrode 14 and the cathode electrode 15 are simultaneously energized. When the anode electrode 14 and the cathode electrode 15 are energized, a high-voltage electric field is generated between them. When the air enters the inside of the protective shell 31, it enters the high-voltage electric field. Corona discharge occurs through the cathode electrode 15, so that the gas is ionized. At this time, the negatively charged gas ions move towards the cathode electrode 15 under the action of the electric field force. During the movement, they collide with the dust particles, so that the dust is charged negatively. After being charged, the dust moves towards the anode electrode 14 under the action of the electric field force. The charged dust releases the electrons it carries after reaching the anode electrode 14, so that the dust is adsorbed on the surface of the anode electrode 14. When a certain weight accumulates, it falls into the collection hopper 21 for collection.

[0036] Step 2, when the dust collected inside the collection hopper 21 reaches a certain level, drive the servo motor 25 to make the ball screw 26 at the output end perform rotational motion. When the ball screw 26 performs rotational motion, it is in threaded cooperation with the ball nut 28, converting the rotational motion of the ball screw 26 into the linear motion of the ball nut 28. One side of the ball nut 28 generates linkage with the rotating shaft 31 through the articulated linkage arm 29, causing the rotating shaft 31 to rotate. At this time, the movable baffle 33 fixed on one side of the rotating shaft 31 performs circular motion with the rotating shaft 31 as the axis. During the movement, a gap is generated in the groove of the control chamber 22. At this time, the dust in the collection hopper 21 falls through the gap between the control chamber 22 and the movable baffle 33 until it falls onto the cleaning box 34 for cleaning by personnel transportation.

[0037] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
