Description

TECHNICAL FIELD

[0001] The present application relates to the field of dust removal, in particular to a dust remover for preventing secondary dust raising. BACKGROUND

[0002] The dust remover for preventing secondary dust raising is an environmental protection equipment for removing dust particles in the air and effectively avoiding the collected dust from flying into the air again.

[0003] The application number CN117379894B discloses a high-efficiency dust remover for preventing secondary dust raising, which comprises a dust removal bin, a dust removal assembly, a dust collection bin, two tooth belts, and a first driving assembly. One side of the dust removal bin is provided with an air inlet for introducing waste gas, and the other side is provided with an air outlet for blowing filtered gas. The dust removal assembly is arranged in the dust removal bin and connected with the dust removal bin for filtering solid particles in the waste gas. In the process of industrial production and environmental management, it is crucial to effectively control dust raising and purify air to ensure production safety and maintain ecological balance. At present, a dust remover for preventing secondary dust raising is widely used in the market. The working principle of this dust remover mainly relies on a rotating rack. Through a clever mechanical structure, the negative pressure device inside and outside the rack is connected. When the equipment starts, the dust floating in the air is quickly captured, and then the dust is sucked into the dust collection bin along the designated channel and released inside the dust collection bin, thereby completing the basic dust removal operation process. However, during actual operation, this dust remover exposes many significant problems. Since the direction of dust suction by the negative pressure device is inconsistent with the final direction of dust transport, a filter screen is arranged at the communication part of the negative pressure device and the rack to block dust particles. However, in actual working conditions, dust particles of different sizes are mixed, and when the size of part of the particles is similar to that of the filter screen, the filter screen holes are easily blocked. Once the filter screen holes are blocked, the negative pressure capacity of the negative pressure device will decrease sharply, directly causing the dust suction effect of the dust remover to be greatly reduced. Although the dust remover is equipped with a cleaning device to try to solve the filter screen blocking problem, the actual cleaning effect is not satisfactory. On the one hand, the cleaning device cannot reach all corners of the filter screen, and part of the blocked screen holes cannot be effectively cleaned. On the other hand, some sticky dust adheres to the filter screen, and even after cleaning, there is still residue, which seriously affects the permeability of the filter screen. Over time, the filtering efficiency of the filter screen continues to decrease, and the negative pressure capacity is difficult to recover to the normal level, so the equipment has to be repaired. The maintenance personnel not only need to spend a lot of time and effort to carefully disassemble many parts to access the blocked filter screen, but also need to use professional tools and equipment to carefully inspect and repair the filter screen during the repair process, which undoubtedly increases the cost of manpower and material resources.

[0004] To solve the above problems, a dust remover for preventing secondary dust raising is proposed. SUMMARY

[0020] 2. The dust collector of the present application prevents secondary dust raising. During the downward movement of the sealing plate, the space inside the first hole increases, causing air with high air pressure above to flow to the area with low air pressure below, resulting in air flow disturbance. This air flow disturbance makes the dust particles in the dust-containing air move more actively inside the second hole, increasing the contact opportunities between the dust particles and the electrostatic plate. Just like stirring in water makes solute mix with solvent faster, the air flow disturbance promotes the dust to be more fully exposed to the electrostatic field, thereby significantly improving the adsorption efficiency of the electrostatic plate to the dust.

[0036] When dust adsorption is needed, the air containing dust enters the inside of the shell 1 from the air inlet pipe 2, the motor 4101 is started to drive the rotating plate 4102 to rotate, and the first guide rod 4105 is driven to rotate. At this time, the first guide rod 4105 is inside the first guide hole 4104, because the outer appearance structure of the first guide hole 4104 is a horizontal straight line, and the matching mode of the first guide hole 4104 and the first guide rod 4105 is a gap fit, the first guide rod 4105 drives the reciprocating plate 4103 to move downward, and drives the first pull rod 4112 and the push rod 4202 above the reciprocating plate 4103 to move downward. At this time, the first sliding block 4111 is inside the sliding groove 4110, the sealing plate 4109 is pulled to move downward, the internal space of the second hole 4108 is increased, under the action of the air pressure difference, the dust-containing air is sucked into the second hole 4108. At this time, the first pull rod 4112 drives the pull plate 501 to move downward, and further drives the fifth guide groove 507 to move downward. The fourth guide rod 509 is at the lower end of the fifth guide groove 507, because the outer appearance structure shape of the horizontal direction of both sides of the fifth guide groove 507 is a vertical straight line, and the outer appearance structure of the upper and lower directions of both sides of the fifth guide groove 507 is an inclined straight line, and the inclination directions of both sides of the fifth guide groove 507 are the same, so that after the sealing plate 4109 moves downward by a certain distance, the fourth guide rod 509 moves to the inside of the upper side of the fifth guide groove 507. The fourth guide rod 509 pushes the third baffle 513 along the inclined edge to move to the inside of the groove 511, so that the fourth guide rod 509 can move to the inside of the sixth guide groove 508. The fourth guide rod 509 drives the second baffle 510 to move to the direction of the second hole 4108, seals the upper side of the second hole 4108, prevents the dust above from moving directly to the lower inside of the shell 1, because the outer appearance structure of the second guide hole 4113 and the third guide hole 4114 is a circular arc, and the arc of the third guide hole 4114 is greater than the arc of the second guide hole 4113, so that the first guide rod 4105 moves to the inside of the second guide hole 4113, so that the reciprocating plate 4103 will not move up and down. At this time, there is time for the static electricity inside the static plate 4106 to adsorb the dust inside the second hole 4108. When the first guide rod 4105 moves to the inside of the third guide hole 4114, it will continue to drive the reciprocating plate 4103 to move downward, drive the sealing plate 4109 to move downward, and move out of the inside of the second hole 4108. Because the width of the upper end of the seventh guide groove 4204 is less than the width of the lower end of the seventh guide groove 4204, and the outer appearance structure of the upper end of the seventh guide groove 4204 is a vertical straight line, and the outer appearance structure of the lower end inside of the seventh guide groove 4204 is an inclined straight line, the second guide rod 4205 moves to the direction of the first hole 4107 along the lower end inside of the seventh guide groove 4204, so that the first pull rod 4112 and the first sliding block 4111 move to the direction of the first hole 4107,When the second slider 4203 side first magnet 4206 is in contact with the second magnet 4207, all magnets are in the state of being attracted. Because the strength of the second slider 4203 side first magnet 4206 is greater than that of the first slider 4111 side first magnet 4206, the second guide rod 4205 continues to rotate and moves to the inside of the other end first guide hole 4104. The reciprocating plate 4103 and the first pull rod 4112 and the push rod 4202 move upward. At this time, the first pull rod 4112 is pushed to restore to the upper end vertical straight line position of the seventh guide groove 4204 under the elastic potential of the elastic expansion rod 4201. The second slider 4203 side first magnet 4206 controls the sealing plate 4109 and drives it to move upward to the inside of the first hole 4107. When the pull plate 501 moves downward, it drives the fourth guide groove 503 to move downward. At this time, the third guide rod 504 is located at point b of the fourth guide groove 503. Because point b of the fourth guide groove 503 is closer to the first hole 4107 than point a, the horizontal direction of the fourth guide groove 503 is vertical and straight, and the upper and lower directions of the fourth guide groove 503 are inclined straight lines, and the upper and lower directions of the fourth guide groove 503 are opposite, so that the third guide rod 504 moves along the upper inclined edge of the fourth guide groove 503 to the direction away from the first hole 4107, opening the upper side of the first hole 4107, so that the sealing plate 4109 can move from the inside of the first hole 4107, and when the third guide rod 504 moves to the lower end of the fourth guide groove 503, it moves to the first hole 4107, pushing the sealing plate 4109 to the position of the first slider 4111, so that the first magnet 4206 inside the first slider 4111 controls the sealing plate 4109 again to attract dust into the inside of the second hole 4108. At this time, the dust with static electricity that was adsorbed in the second hole 4108 the last time is pushed down by the sealing plate 4109 and falls into the inside of the shell 1, preventing secondary dust raising. Because the sealing plate 4109 leads the dust to the direction where the dust eventually goes, there is no need to set a filter screen to block it, thereby reducing the cost of subsequent manpower and material resources.

[0037] Because the dust with static electricity that was adsorbed in the second hole 4108 the last time is pushed down by the sealing plate 4109, the dust inside it is pushed in one direction and accumulates together under the action of static electricity, making it larger and more likely to fall. Dust that reacts with water easily, such as magnesium powder and aluminum powder, does not need to use water to assist dust to fall.

[0038] When the fourth guide rod 509 drives the second baffle 510 to move toward the second hole 4108 to seal the upper part of the second hole 4108, the first guide rod 4105 is inside the first guide hole 4104, and continues to drive the first pull rod 4112, the first sliding block 4111 and the sealing plate 4109 to move downward. At this time, the space inside the second hole 4108 is constantly increasing, and the air with high air pressure at the top pushes to the area with low air pressure at the bottom, causing air flow disturbance and increasing the probability of dust being adsorbed by the electrostatic plate 4106. When the first guide rod 4105 is inside the first guide hole 4104 and the second guide hole 4113, the sealing plate 4109 remains stationary for a period of time, during which there is no air flow disturbance, and the electrostatic plate 4106 stably adsorbs the dust.

[0039] The rack adsorbs the dust and moves it to the lower part of the shell 1. In addition, due to gravity and other reasons, the dust that falls on the rack is also difficult to fall and increases the probability of secondary dust raising. However, in the device, all the gas above the shell 1 needs to pass through the first hole 4107 for a period of time before reaching the inside of the lower part of the shell 1, reducing the probability of dust entering the shell 1 without any restraint, and further reducing the probability of secondary dust raising.
