Description

Technical Field

[0001] The invention relates to the technical field of electrostatic dust removal, in particular to a self-cleaning anode plate based on electrostatic dust removal equipment. Background Art

[0002] In the field of gas dust removal, electrostatic dust removal is a widely used dust removal method. Its dust removal principle is to separate dust-containing gas by electricity when it passes through a high-voltage electrostatic field. The dust combines with negative ions to carry negative charges, causing the dust to tend to and adhere to the anode surface, thereby achieving the purpose of dust removal. The electrostatic dust removal equipment prepared based on this principle has the advantages of high dust removal efficiency, large purification capacity and simple structure, and has a wide range of practical applications.

[0003] In traditional electrostatic precipitator equipment, after the anode plates have been used for a period of time, a lot of dust will adhere to the surface of the anode plates. It is necessary to use a vibrating component to hammer the anode plates to separate the dust attached to the surface of the anode plates. The dust is then collected by a dust collecting structure to ensure that the anode plates maintain a good dust absorption effect.

[0004] However, in the process of cleaning the dust on the surface of the anode plate by vibration, since the structure of the existing anode plate is relatively simple and the thickness of the anode plate is also relatively thin, the dust cleaning by vibration will damage the surface of the anode plate assembly, causing the anode plate to deform; on the other hand, the vibration will cause the dust attached to the surface of the anode plate to be lifted up again and dispersed in the electrostatic dust removal equipment. The chamber where the anode plate of the traditional dry electrostatic dust removal equipment is located is close to the airflow outlet, and the dust that is dispersed again is easy to flow out along the outlet, affecting the comprehensiveness of dust collection and causing environmental pollution. Summary of the invention

[0005] The object of the present invention is to provide a self-cleaning anode plate based on an electrostatic precipitator to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a self-cleaning anode plate based on an electrostatic dust removal device, comprising a dust removal bin, a plurality of anode plate bodies and a driving mechanism;

[0007] The plurality of anode plate bodies are all arranged inside the dust removal bin, and each of the anode plate bodies comprises a plurality of screw holes, and each of the screw holes is distributed around the anode plate body;

[0008] The driving mechanism includes multiple driving rods and a driving motor. The surface of each driving rod is provided with multiple threaded segments. Each anode plate body is respectively arranged in a threaded segment. The rotation directions of the threads in adjacent threaded segments are opposite, and the threads are meshed with the inner wall of the screw hole. The driving motor drives the multiple driving rods to rotate.

[0009] Preferably, each of the anode plate bodies further comprises a reinforcing plate, an insulating layer and a conductive layer;

[0010] The conductive layer is arranged on the surface of the anode plate body, the reinforcing plate is located inside the anode plate body, and the insulating layer is located between the reinforcing plate and the conductive layer.

[0011] Preferably, each of the anode plate bodies further comprises a plurality of connection terminals, and each of the connection terminals is connected to the conductive layer.

[0012] Preferably, a sprocket is provided at one end of each driving rod passing through the dust removal bin.

[0013] Preferably, the driving mechanism further comprises a chain and a driving wheel;

[0014] The driving wheel is meshed with the chain links of the chain and the output end of the driving motor respectively;

[0015] The chain links of the chain are all rotatably engaged with one end of a plurality of driving rods.

[0016] Preferably, the driving mechanism further comprises a control mechanism;

[0017] The control mechanism comprises an identification probe and an identification tag, and the identification tag is arranged on the surface of the driving wheel.

[0018] Preferably, the identification tag includes two turn tags and a reset tag;

[0019] The two turning labels are symmetrically distributed with respect to the resetting label.

[0020] Preferably, the plurality of anode plate bodies are distributed in parallel.

[0021] Preferably, the cross section of each anode plate body is in the shape of a broken line.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention achieves the effect of driving the anode plate bodies to squeeze each other by arranging a driving rod and a threaded segment. During the synchronous rotation of the driving rod, the threads with opposite rotation directions in adjacent threaded segments can synchronously drive adjacent anode plate bodies to approach or move away from each other, thereby achieving the effect of mutual squeezing and separation between multiple anode plate bodies. Through the squeezing between the anode plate bodies, the dust attached to the surface of the anode plate can be squeezed into a cake shape. When the anode plate bodies are separated, the dust cakes are separated from the surface of the anode plate bodies under the action of gravity, which not only has a better cleaning effect on the surface of the anode plate bodies, but also can effectively avoid the problem of dust escaping again in the dust removal bin, and fully guarantees the comprehensiveness of dust collection.

[0024] 2. The present invention achieves the effect of improving the strength of the anode plate body itself by setting a reinforcing plate. The reinforcing plate is used as the main component of the anode plate body, which can effectively enhance the strength of the anode plate body itself, so that the anode plate body can withstand a certain pressure, so that when the anode plate bodies are close to each other, the dust attached to the surface of the anode plate body can be squeezed out, and at the same time, the deformation of the anode plate body can be prevented.

[0025] 3. The present invention achieves the effect of automatically controlling the movement stroke of the anode plate body by setting up a control mechanism. The control mechanism can flexibly control the forward and reverse rotation of the driving rod, thereby controlling the mutual approach and separation between the anode plate bodies, and can also maintain a certain distance between the anode plate bodies, which is conducive to airflow.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 8 , the present invention provides the following two embodiments:

[0040] Embodiment 1:

[0041] See also Figure 1 A self-cleaning anode plate based on an electrostatic dust removal device includes a dust removal bin 100, a plurality of anode plate bodies 200 and a driving mechanism 300, wherein the driving mechanism 300 is used to drive the plurality of anode plate bodies 200 to move inside the dust removal bin 100.

[0042] See also Figures 1 to 3 A plurality of anode plate bodies 200 are arranged inside the dust removal bin 100, and are distributed in parallel. The cross section of each anode plate body 200 is in a broken line shape. The use of a wavy anode plate body 200 can increase the contact area with the dust-containing gas, and the wavy anode plate body 200 can disrupt the original airflow pattern, so that the dust-containing gas can fully contact the surface of the anode plate body 200, thereby improving the comprehensiveness of dust adsorption.

[0043] See also Figure 3 and Figure 4 Each anode plate body 200 includes a plurality of screw holes 210 , and each screw hole 210 is distributed around the anode plate body 200 .

[0044] See also Figure 2 , Figure 5 and Figure 6 The driving mechanism 300 includes a plurality of driving rods 310 and a driving motor 340. The surface of each driving rod 310 is provided with a plurality of threaded sections 311. A sprocket is provided at one end of each driving rod 310 that passes through the dust removal bin 100. Each anode plate body 200 is respectively disposed in a threaded section 311. The threads in adjacent threaded sections 311 rotate in opposite directions, and the threads are meshed with the inner wall of the screw hole 210. The driving motor 340 drives the plurality of driving rods 310 to rotate.

[0045] The driving mechanism 300 further includes a chain 320 and a driving wheel 330 . The driving wheel 330 is respectively engaged with the links of the chain 320 and the output end of the driving motor 340 . The links of the chain 320 are all rotatably engaged with one end of the plurality of driving rods 310 .

[0046] When the driving rod 310 rotates synchronously, the threads with opposite rotation directions in adjacent threaded segments 311 can synchronously drive the adjacent anode plate bodies 200 to move closer to or away from each other. When the adjacent side surfaces of the anode plate bodies 200 are close to each other until they are tightly attached, the dust on the surface of the anode plate bodies 200 can be squeezed and the air between the dust can be squeezed out to form a dense pancake shape.

[0047] When the anode plate bodies 200 are separated from each other, the dust cakes slide along the anode plate bodies 200 under the action of their own gravity and fall into the dust collecting hopper below the dust removal bin 100 .

[0048] When the anode plate body 200 is separated, the surface on the other side of the anode plate body 200 approaches the surface of another anode plate body 200, thereby squeezing and removing dust on both sides of one anode plate body 200. After the multiple anode plate bodies 200 are squeezed and separated from each other, the dust on the surface of the anode plate body 200 is completely removed, achieving the effect of comprehensive self-cleaning of the surface of the anode plate body 200.

[0049] Secondly, the anode plate bodies 200 are squeezed against each other, squeezing the dust attached to the surface of the anode plate body 200 into a cake shape, and then falling off from the surface of the anode plate body 200, which can effectively avoid the problem of dust escaping again during the falling collection process, and fully ensure the comprehensiveness of dust collection.

[0050] See also Figure 3 Each anode plate body 200 further includes a reinforcing plate 220 , an insulating layer 230 and a conductive layer 240 . The conductive layer 240 is disposed on the surface of the anode plate body 200 , the reinforcing plate 220 is located inside the anode plate body 200 , and the insulating layer 230 is located between the reinforcing plate 220 and the conductive layer 240 .

[0051] The reinforcing plate 220 is used as the main component of the anode plate body 200, which can effectively strengthen the strength of the anode plate body 200, so that the anode plate body 200 can withstand a certain pressure, so that when the anode plate bodies 200 are close to each other, the dust attached to the surface of the anode plate body can be squeezed out. At the same time, the anode plate body 200 is prevented from being deformed, and the service life of the anode plate body 200 is effectively extended.

[0052] The insulating layer 230 is made of non-metallic insulating material and is used to isolate the reinforcing plate 220 from the conductive layer 240 , preventing the conductive layer 240 from transmitting current to the reinforcing plate 220 and the driving rod 310 , thereby achieving a protective insulation effect.

[0053] Each anode plate body 200 also includes a plurality of connection terminals 250, each of which is connected to the conductive layer 240. The connection terminals 250 can connect an external power source to the conductive layer 240, so that the conductive layer 240 generates positive charge after being energized, which is used to ensure a normal electrostatic dust removal effect.

[0054] See also Figure 7 and Figure 8 The driving mechanism 300 also includes a control mechanism 350, through which the forward and reverse rotation of the driving rod 310 can be flexibly controlled, thereby controlling the mutual approach and separation between the anode plate bodies 200, and can also maintain a certain distance between the anode plate bodies 200, so that the dust-containing gas can flow fully between the anode plate bodies 200, ensuring that the anode plate bodies 200 can fully absorb the dust in the airflow.

[0055] The control mechanism 350 includes an identification probe 351 and an identification tag 352, and the identification tag 352 is disposed on the surface of the driving wheel 330. The identification tag 352 includes two turning tags 353 and a reset tag 354, and the two turning tags 353 are symmetrically distributed with respect to the reset tag 354.

[0056] When the identification tag 352 is close to the identification probe 351, the identification probe 351 can output a corresponding control signal. When the identification probe 351 is close to the reset tag 354, a stop signal is output to control the drive motor 340 to stop running, so that a certain distance is maintained between the multiple anode plate bodies 200, which facilitates the dust-containing air to flow between the anode plate bodies 200.

[0057] When the identification probe 351 approaches the turning tag 353, a turning signal is output to control the driving motor 340 to rotate in the opposite direction, thereby driving the driving rod 310 to reverse synchronously, so as to achieve the effect of the anode plate 200 moving in the opposite direction, so that the multiple anode plate bodies 200 are close to and separated from each other, so as to achieve the effect of squeezing the anode plate bodies 200 against each other, and achieving the effect of completely removing dust from the surfaces of both sides of the anode plate bodies 200.

[0058] Embodiment 2:

[0059] Based on the above disclosure of the present invention, another embodiment is proposed:

[0060] After adjacent anode plate bodies 200 complete one approach and one separation, the identification probe 351 approaches the reset tag 354, so that the drive motor 340 stops running and keeps the distance between the multiple anode plate bodies 200 the same for the flow of dust-laden gas.

[0061] In order to prevent the problem of dust blocks remaining on the surface of the anode plate body 200, multiple turning instructions can be output again, that is, the identification probe 351 passes through the two turning labels 353 multiple times, driving the anode plate body 200 to move back and forth multiple times, and the anode plate bodies 200 collide with each other, thereby generating vibrations, and completely removing the dust blocks remaining on the surface of the anode plate body 200, thereby achieving comprehensive cleaning of the surface of the anode plate body 200.

[0062] The fallen dust blocks enter the collecting bucket below the dust removal bin 100 by gravity, and the collecting bucket discharges the collected dust.

[0063] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
