Description

Technical Field

[0001] The present invention belongs to the technical field of electrolytic cell optimization, and particularly relates to an AEM electrolytic cell device based on flow channel optimization. Background Technique

[0002] AEM electrolytic cell: Anion exchange membrane electrolytic cell, membrane electrode type: Using pure water or low-concentration alkaline electrolyte, water molecules are electro-reduced to hydrogen at the cathode of the membrane electrode to generate hydroxide ions. Thereafter, the hydroxide ions are transported to the anode through the AEM membrane and finally oxidized to oxygen at the anode; Analysis of the actual working conditions of the AEM electrolytic cell in a high-concentration dust environment: Dust particles tend to deposit in the gaps between the bipolar plates, cathode electrodes, anode electrodes, gaskets and diaphragms, resulting in a local decrease in the flow velocity of the electrolyte flow field or even a cut-off of the flow. In addition, eddy currents or dead volumes will form downstream of the blocked area until the electrolyte stagnates, and the local hydroxide ion concentration gradient is unbalanced, affecting the ion conduction efficiency; Dust adsorbs on the surfaces of the aforementioned components or in the overlapping gaps, hindering the contact between the electrolyte and the catalyst layer, resulting in an increase in the mass transfer resistance of the reactants ( ), and products ( , ). At the same time, dust deposits on the membrane surface to form a "pollution layer", increasing the diffusion path of ions through the membrane and resulting in an increase in the concentration polarization voltage; When high-concentration dust flows at high speed with the electrolyte, erosion wear is caused on the grooves of the flow field plate or the surface of the current collector, resulting in an increase in the roughness of the flow channel and an increase in the pressure drop; and hard dust particles scratch the membrane surface under the action of the flow field pressure, forming micro-cracks or holes, resulting in the cross-flow of the cathode and anode electrolytes.

Double-opening bins are clamped and installed at both ends of the shovel plate. Angle valves are inserted and installed on the end face of the double-opening bin close to the wall plate. One end of the panel is clamped and installed with a dust reduction cylinder that is clamped and fitted with the C-shaped bracket. The dust reduction cylinder has the same appearance as the dust cylinder. Angle pipes are symmetrically inserted and installed on the outer wall of the dust reduction cylinder. Pillars are clamped and installed on the outer walls of the vertical sections on one side of the C-shaped bracket and the tooling bracket.

[0009] Preferably, the adjustment unit includes: Annular guide rails, which are symmetrically rotatably fitted on the outer walls on both sides of the adjustment disc, and the inner diameter of the inner wall of the annular guide rail is larger than the inner diameter of the adjustment disc; Fitting seats, which are slidably clamped and installed on the end faces on both sides of the adjustment disc; Connecting rods, which are circumferentially clamped and installed on the end face of the annular guide rail close to the adjustment disc.

[0010] Preferably, the side of the sponge pad close to the axis of the adjustment disc is an arc surface, and the inner diameter of the arc surface is equal to the outer diameter of the electrode assembly. The bristles of the flexible brush are adapted to the end in contact with the sponge pad. The longitudinal section of the shovel plate is an open ring, and it is an equally divided open ring of the number of vertical rods. The shovel plate is tangent to the double-opening bin. In addition, the cross section of the shovel plate is an isosceles trapezoid, and the shovel plate is subjected to a draft process.

[0011] A method for cleaning dust on the outer wall of the electrolytic cell electrode assembly uses the above-mentioned AEM electrolytic cell device based on flow channel optimization for cleaning. The specific steps are as follows: S1: First, push the connecting rod through the fitting seat on one side to cause the mouth ring at the corresponding position to rotate by a specified angle. At this time, under the guiding and limiting action of the mouth groove, the pillar controls the movable telescopic column to drive the entire tooling bracket to move towards the axis direction of the adjustment disc until the sponge pad is directly opposite to the "first" electrode assembly during the passing process; S2: Then, control the sponge pad to move towards the axis direction of the adjustment disc through the electric telescopic rod until the sponge pad contacts the electrode assembly. Before this, the external cleaning liquid can be sprayed in an atomized form onto the working surface of the sponge pad through the water holes in the water storage tank by the water valve, and by gradually changing the aperture size of the water holes, quantitative and uniform spraying on the working surface of the sponge pad can be achieved; In this process, the continuous operation of the sponge pads in different areas is changed alternately by the intermittent rotation of the rotating wheel, and the dust particles existing on the working surface of the sponge pad after adsorption are dried and separated in the cleaning room through the heating of the electric heating plate and the interaction between the flexible roller brush and the working surface of the sponge pad, and are pumped into the dust cylinder through the air duct and the conduit, so as to ensure the adsorption between the single sponge pad and the dust particles on the surface of the electrode assembly, and complete the pre-treatment of dust removal on the surface of the electrode assembly; S3: Finally, the shovel plate that moves synchronously with the knob constantly interacts with the dust on the surface of the electrode assembly during movement. At the same time, the double openings guide and adsorb the dust on the end surface of the shovel plate and the area between the shovel plate and the vertical fixing rod, thereby reducing the accumulation of dust on the surface of the electrode assembly. In addition, during the specific implementation, the degree of interaction between the shovel plate and the surface of the electrode assembly is synchronously adjusted by fine-tuning the rotation angle of the mouth ring, thereby realizing the gradual cleaning process of the dust deposited on the outer surface of the electrode assembly by the shovel plate, and homogenizing the friction between the dust particles and the shovel plate in a single cleaning, avoiding excessive rigid contact between the dust particles and the electrode assembly, reducing scratches, and increasing the service life of the electrode assembly.

[0012] The present invention has the following beneficial effects: 1. The present invention uses a rotating wheel to alternately change the contact integrity between the sponge pad at different positions and the dust particles on the outer end surface of the electrode assembly, and through the heating of the electric heating plate and the equal interaction between the flexible roller brush and the working surface of the sponge pad, the dust particles on the surface of the sponge pad in the adsorption state are dried and separated inside the cleaning room, ensuring the adsorption of the sponge pad in a single contact with the outer surface of the electrode assembly. At the same time, through the atomization of the cleaning liquid on the working surface of the sponge pad, the interfacial tension between the dust tube electrode assembly is reduced, so that hydrophobic dust or charged dust is accelerated to separate from its surface, and the "micro-infiltration" of the sponge pad can dissolve and infiltrate dust particles, avoid secondary dusting caused by dry cleaning, help protect the surface of the electrode assembly, and reduce the probability of rigid contact scratches between the dust and the surface of the electrode assembly.

[0013] 2. The present invention promotes the relative movement between the shovel plate and the node plate to continuously generate relative movement between the shovel plate and the dust on the electrode surface, and expands the solid phase contact area through the dust groove, thereby strengthening the shovel plate's interception and guiding effect on dust particles, ensuring that the dust flows along the arc surface of the shovel plate to the double-opening area, and finally through the suction effect of the air duct, the dust on the arc surface of the shovel plate and the dust between the double opening and the vertical fixed rod are pumped into the dust cylinder through the duct, thereby further improving the collection degree of dust on the surface of the electrode assembly, reducing the risk of dust filling and penetrating into the overlapping gaps of the electrode assembly, and improving the flow field stability between the electrode assemblies.

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] It should be noted that the terms “vertical”, “horizontal”, “left”, “right” and similar expressions used in this document are only for the purpose of explanation and do not represent the only implementation method.

[0029] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0030] Reference Figure 2 , Figure 3 and Figure 7 It can be seen that an AEM electrolyzer device based on flow channel optimization includes a node disk, an adhesion unit 2 is evenly arranged on one side of the inner wall of the node disk in the circumferential direction, a gradient cleaning unit 3 corresponding to the adhesion unit 2 is arranged on one side of the adhesion unit 2, and an adjustment unit 4 is arranged on the outer side of the node disk; Reference Figure 1 , Figure 2 and Figure 3 It can be seen that a chassis 11 is arranged in the outer space of the section disk, and air vents 12 are evenly opened on the outer wall of the vertical section of one side of the chassis 11, and a pair of outer walls of the chassis 11 are symmetrically clamped with angle bars 13 for auxiliary heat dissipation, and rails 14 are clamped and installed in the middle position of the inner wall of the horizontal section of the chassis 11, and a base shaft 15 is clamped and installed on the inner wall of the vertical section of one side of the chassis 11, and a bracket 16 opposite to the base shaft 15 is clamped and installed on the inner wall of the vertical section of the other side of the chassis 11, and an electrolytic cell frame 17 is installed between the base shaft 15 and the bracket 16, and vertical fixing rods 18 are evenly distributed circumferentially between the electrolytic cell frames 17, and the vertical fixing rods 18 are detachably connected to the electrolytic cell frames 17 by bolts, and an electrode assembly 19 is clamped and installed between the electrolytic cell frames 17; Reference Figure 3 and Figure 6It can be seen that the adjustment unit 4 includes: an annular guide rail 41, which is symmetrically rotatably mounted on the outer walls of both sides of the node disk, and the inner wall diameter of the annular guide rail 41 is larger than the inner diameter of the node disk; an engaging seat 42, which is slidably mounted on the end faces of both sides of the node disk; a connecting rod 43, which is circumferentially mounted on the end face of the annular guide rail 41 close to the node disk, and the connecting rod 43 is slidably mounted with the node disk while being slidably mounted with the engaging seat 42; a mouth ring 44, which is mounted on the end face of the annular guide rail 41 away from the node disk; a mouth groove 45, which is evenly arranged on the outer wall of the mouth ring 44 in the circumferential direction, and is slidably mounted with the support 316; an angle steel frame 46, which is symmetrically mounted on the outer wall of the node disk, and is slidably mounted with the angle steel frame 46 and the rail 14.

[0031] The adhesion unit 2 and the gradient cleaning unit 3 reciprocate along the axis of the vertical fixing rod 18 and the adhesion unit 2 and the gradient cleaning unit 3 move in a simple process: First, the angle steel frame 46 drives the section plate to move along the axis of the vertical rod 18 under the support and guidance of the rail 14, and in this process, the base shaft 15 and the bracket 16 assist the chassis 11 to provide a stable working environment for the angle steel frame 46 to move, ensuring the same frequency between the section plate and the chassis 11 and the electronic components during the movement. In specific implementation, the angle steel frame 46 can be driven to move by an electric slider; It is hereby explained that in a specific implementation, the adhesion unit 2, the gradient cleaning unit 3 and the cleaning unit in the present invention can be symmetrically distributed by adding a knob, so as to achieve the consistency of operation on the surface of the electrode assembly 19 when the adhesion unit 2 and the gradient cleaning unit 3 reciprocate; Next, through the interaction between the fitting seat 42 and the connecting rod 43, the connecting rod 43 is guided by the pitch plate to synchronously drive the mouth ring 44 to rotate a certain angle. In specific implementation, the fitting seat 42 can be driven to move by an electric slider; Finally, through the rotation of the mouth ring 44, the mouth groove 45 interacts with the internal components of the adhesion unit 2 or the gradient cleaning unit 3 (see the subsequent introduction), so that the adhesion unit 2 and the gradient cleaning unit 3 are reciprocated along the radial direction of the pitch disk to the specified position as a whole; Chassis 11, air vent 12: Physical isolation blocks the dust intrusion path, airflow control creates a clean micro-environment, structural reinforcement resists wear and corrosion, and maintenance optimization reduces downtime costs, achieving comprehensive benefits such as delayed electrolytic cell efficiency attenuation, extended life, and reduced failure rate; Corner bar 13: On the one hand, it increases the internal heat dissipation path of the chassis 11, optimizes the heat dissipation method, helps to inhibit thermal degradation and expansion of the membrane, and at the same time, to a certain extent, can prevent electrode corrosion and inactivation of active sites; on the other hand, it can provide a stable fulcrum installation point for external connection components, improve transportation or operation stability, and ensure equipment safety.

[0032] Reference Figure 7 , Figure 8 and Figure 9 It can be seen that the adhesion unit 2 includes: a top arc seat 21, which is evenly clamped and installed on one side of the inner wall of the node plate in the circumferential direction; a movable telescopic column 22, which is symmetrically clamped and installed on the end face of the top arc seat 21 close to the axis of the node plate; a tooling frame 23, which is clamped and installed on one end of the two movable telescopic columns 22 away from the top arc seat 21; a guard plate 24, which is clamped and installed on the outer walls of both sides of the vertical section of the tooling frame 23; an electric telescopic rod 25, which is symmetrically clamped and installed on the end face of the horizontal section of the tooling frame 23 away from the top arc seat 21; an end plate 26, which is clamped and installed on one end of the electric telescopic rod 25 away from the top arc seat 21; an ear seat 27, which is clamped and installed on the end face of the end plate 26 away from the top arc seat 21; a rotating wheel 28, which is rotatably mounted between the two ear seats 27; a support plate 29, which is a group of four and is circumferentially clamped and installed on the outer wall of the rotating wheel 28; Reference Figure 8 and Figure 10 It can be seen that a sponge pad 211 is mounted on the end face of the support plate 29 away from the axis of the rotating wheel 28, a cleaning chamber 212 is mounted on the middle position of the end face of the horizontal section of the tooling frame 23 away from the top arc seat 21, a group of relative inner walls of the cleaning chamber 212 are mounted with electric heating plates 213, and another group of relative inner walls of the cleaning chamber 212 are mounted with a flexible roller brush 214 for rotational cooperation, an outer wall of one side of the cleaning chamber 212 is symmetrically mounted with an air duct 215, a dust cylinder 216 is mounted on one side of the horizontal section of the tooling frame 23, and a guide tube 217 is symmetrically mounted on the outer wall of one side of the dust cylinder 216; Reference Figure 8 and Figure 9 It can be seen that a water tank 221 is clamped and installed on the inner wall of the guard plate 24 on one side, and the length and width of the water tank 221 are larger than the sponge pad 211, and the cross-sectional shape of the water tank 221 is a right-angled trapezoid, and water holes 222 are evenly opened on the end face of the water tank 221 close to the sponge pad 211, and the diameter of the water hole 222 decreases gradually along the gravity direction, and a water valve 223 that passes through the guard plate 24 is plugged and installed on the end face of the water tank 221 away from the sponge pad 211; the side of the sponge pad 211 close to the axis of the node plate is an arc surface, and the inner diameter of the arc surface is equal to the outer diameter of the electrode assembly 19, and the bristles of the flexible roller brush 214 are adapted to the end in contact with the sponge pad 211.

[0033] It is hereby explained that the width of the sponge pad 211 is at least equal to the vertical distance between the outer wall of the opposite guard plate 24, and the radial vertical height difference between the sponge pad 211 and the guard plate 24 along the segment disk is at least equal to the difference between the outer diameters of the electrode assembly 19 and the electrolytic cell frame 17; The adsorption process of the sponge pad 211 on the dust on the surface of the electrode assembly 19 (the area between adjacent vertical fixing rods 18): First, at the beginning of the movement, one end face of the sponge pad 211 (in specific implementation, the adhesion unit 2 is at the front end of the gradient cleaning unit 3 in the traveling direction and is close to the gradient cleaning unit 3) is tangent to the intersection surface between the electrode assembly 19 and the electrolytic cell frame 17; In specific implementation, under the support and guiding action of the aforementioned angle steel frame 46 on the strip rail 14, the driving dial can be driven to drive the adhesion unit 2 to move along the axis of the vertical rod 18, so as to adjust the tangency of one end face of the sponge pad 211, the intersection surface of the electrode assembly 19 and the electrolytic cell frame 17; Next, the mouth ring 44 rotates by a specified angle. Under the limiting and squeezing action of the mouth groove 45 on the support column 316 (the meshing degree between the mouth groove 45 and the support column 316 is the maximum movable distance (extension or contraction) of the tooling frame 23. At this time, the sponge pad 211 is not in contact with the surface of the electrode assembly 19), the tooling frame 23 is synchronously driven to move towards the axis direction of the dial (and when the tooling frame 23 moves towards the axis direction of the dial, the rotation direction of the mouth ring 44 is positive). During this process, the sponge pad 211 is limited between adjacent vertical rods 18 through the top arc seat 21, and at the same time, through the movable telescopic column 22, further stable support and guidance are provided for the movement of the tooling frame 23; Finally, under the control of the extension of the electric telescopic rod 25, the end plate 26 synchronously drives the ear seat 27 to move towards the axis direction of the dial until the sponge pad 211 comes into contact with the surface of the electrode assembly 19 (before this, the water valve 223 and the cleaning liquid are connected through an external hose, and then the cleaning liquid is stably pumped into the water storage tank 221 through an external water pump, and then atomized cleaning liquid is sprayed onto the working surface of the sponge pad 211 in the current area through the water holes 222. And by changing the relative angle between the inclined plane of the water storage tank 221 and the sponge pad 211, the diameter of the water holes 222 is linearly adjusted to reduce the uniformity of different areas under the action of centrifugal force and gravity when the sponge pad 211 rotates. At the same time, through the atomized cleaning liquid, the excessive accumulation of the cleaning liquid in the sponge pad 211 is reduced, and the penetration of the cleaning liquid between the overlapping gaps of the electrode assembly 19 is reduced (in specific implementation, the electrolytic reaction of the electrolytic cell will continuously dissipate heat to the outside, which can just thermally decompose the cleaning liquid in the aforementioned sponge pad 211)); At the same time, the position of the sponge pad 211 can be alternately changed by the intermittent rotation of the rotating wheel 28, and when the sponge pad 211 is opposite to the cleaning chamber 212 after the adsorption operation is completed, the electric telescopic rod 25 drives the sub-rotating wheel 28 to move in the opposite direction to the top arc seat 21 as a whole, until the sponge pad 211 interacts with the flexible roller brush 214 to the same extent (the vertical distance from any point on the arc surface of the sponge pad 211 to the corresponding bristles of the flexible roller brush 214 is equal, avoiding different degrees of interaction and excessive damage to the bristles of the flexible roller brush 214 and the sponge pad 211), and the sponge pad 211 and the flexible roller brush 214 in the cleaning chamber 212 are dried by the heating effect of the electric heating plate 213 (in specific implementation, a sealing ring can be added at the open end of the cleaning chamber 212 to prevent the dried dust particles from splashing to the outside), and in specific implementation, the rotating wheel 28 or the flexible roller brush 214 can be driven to rotate by an external motor or a micro motor; The air duct 215 and the conduit 217 are connected by an external hose, and the dust in the relative motion state inside the cleaning chamber 212 is pumped into the dust cylinder 216 by an external centrifugal fan, so as to realize the self-cleaning process of the surface of the sponge pad 211 and ensure the adsorption effectiveness of the current working surface of the sponge pad 211; The working surface of the sponge pad 211 in the immersed state can effectively avoid mechanical damage and inhibit electrochemical pollution residue (chelating agents (such as EDTA) or corrosion inhibitors in the cleaning solution can combine with harmful ions and be removed simultaneously with sponge wiping to avoid secondary pollution).

[0034] Reference Figure 7 , Figure 11 and Figure 12 It can be seen that the gradient cleaning unit 3 includes: a wall plate 31, which is circumferentially clamped and installed in the space on the other side of the inner wall of the node disk, and corresponds one to one with the top arc seat 21; in addition, the wall plate 31 and the top arc seat 21 have the same appearance; a telescopic rod 32, which is symmetrically clamped and installed on the end face of the wall plate 31 close to the axis of the node disk; a panel 33, which is one in number and is clamped and installed on the end of the telescopic rod 32 away from the wall plate 31; a mouth frame 34, which is clamped and installed on the outer wall of the panel 33; a column 35, which is slidably clamped and installed between the horizontal section of the mouth frame 34 and the panel 33; a reset spring 36, which is sleeved and installed on the outer wall of the column 35 and is located between the horizontal section of the mouth frame 34 and the panel 33; a shovel plate 37, which is symmetrically clamped and installed on the ends of the two columns 35 away from the wall plate 31; Reference Figure 5 , Figure 7 and Figure 11It can be seen that a dust groove 311 is formed on the end face of the shovel plate 37 on the side far from the axis of the column 35, and the number of dust grooves 311 is at least two. Double-opening bins 312 are clamped and installed at both ends of the shovel plate 37. An angle valve 313 is inserted and installed on the end face of the double-opening bin 312 close to the wall plate 31. One end of the panel 33 is clamped and installed with a dust reduction cylinder 314 that is clamped and cooperated with the C-shaped port frame 34. The dust reduction cylinder 314 has the same appearance as the dust cylinder 216. Angle pipes 315 are symmetrically inserted and installed on the outer wall of the dust reduction cylinder 314. Pillars 316 are clamped and installed on the outer walls of the vertical sections on one side of the C-shaped port frame 34 and the tooling rack 23; The longitudinal section of the shovel plate 37 is in the shape of an open ring 44, and it is an equally divided open ring 44 of the number of vertical rods 18. The shovel plate 37 is tangent to the position between the double-opening bins 312. In addition, the cross section of the shovel plate 37 is an isosceles trapezoid, and the shovel plate 37 is subjected to a draft process.

[0035] It is hereby explained that the height of the shovel plate 37 is at least equal to the difference between the outer diameters of the electrode assembly 19 and the electrolytic cell frame 17, and the width between the symmetrically distributed shovel plates 37 is at least equal to the width of the C-shaped port frame 34; The cleaning process of the shovel plate 37 for completely supplementing the partition on the surface of the electrode assembly 19 (compared with the aforementioned sponge pad 211): Similarly, through the movement cooperation between the angle steel frame 46 and the strip rail 14, the control disk can be used to synchronously control the movement of the shovel plate 37 until the end face of the shovel plate 37 far from the adhesion unit 2 is tangent to the intersection surface of the electrode assembly 19 and the electrolytic cell frame 17; By rotating the mouth ring 44, under the limit of the mouth groove 45, the pillar 316 controls the C-shaped port frame 34 under the support and guidance of the telescopic rod 32, so that the column 35 drives the shovel plate 37 to move towards the electrode assembly 19 synchronously. Specifically, during implementation, the relative distance between the shovel plate 37 and the surface of the electrode assembly 19 can be finely adjusted by the rotation angle of the mouth ring 44 (by the elastic recovery of the return spring 36 itself, changing the interaction degree between the shovel plate 37 and the electrode assembly 19), so as to control the equal cutting of the dust layer during the single movement of the shovel plate 37, and realize progressive scraping and shearing; On the one hand, it avoids dust accumulation (the segmented distribution of the shovel plate 37 can further reduce the phenomenon of dust accumulation), and reduces the probability of excessive rigid contact between the dust and the surfaces of the shovel plate 37 and the electrode assembly 19; on the other hand, it can cooperate with the aforementioned sponge pad 211 to dissolve and adhere a layer of dust, and the shovel plate 37 scrapes off one layer, ensuring the scraping accuracy and improving the "softness" of the contact between the shovel plate 37 and the electrode assembly 19; Double-opening bin 312, dust trough 311, angle valve 313, angle tube 315 and dust suppression barrel 314: An external hose connects the angle valve 313 and the angle tube 315, and an external centrifugal fan is used to form a certain negative pressure zone between the opening end of the double-opening bin 312 and the external space, so that the dust on the arc surface of the shovel plate 37 and the dead corner dust between the double-opening bin 312 (symmetrically) and the vertical fixing rod 18 are continuously flowed to the inside of the dust suppression barrel 314 under the action of negative pressure; By effectively unifying the consistency of the arc surface between the double-opening bin 312 and the shovel plate 37, and cooperating with the dust groove 311 to enhance the drainage guidance of the dust during the passage, the flow field of the dust flowing to the double-opening bin 312 is optimized, and the amount of dust retained on the surface of the electrode assembly 19 is reduced (please refer to it for details).

[0036] The present invention provides an AEM electrolytic cell device based on flow channel optimization, and the working principle is as follows: the first step: first, the connecting rod 43 is pushed through the one side fitting seat 42 to cause the corresponding position ring 44 to rotate a specified angle. At this time, the support 316 controls the movable telescopic column 22 to drive the tooling frame 23 to move toward the axis direction of the section plate as a whole under the guiding and limiting action of the mouth groove 45, until the sponge pad 211 is in the same process as the "first" electrode assembly 19 and is positively distributed; Step 2: Then, the electric telescopic rod 25 is used to control the sponge pad 211 to move toward the axis of the section plate until the sponge pad 211 contacts the electrode assembly 19. Prior to this, the external cleaning liquid can be sprayed onto the working surface of the sponge pad 211 in the form of atomization through the water hole 222 in the water tank 221 through the water valve 223, and the aperture size of the water hole 222 is changed in a gradient manner to achieve quantitative and uniform spraying on the working surface of the sponge pad 211; In this process, the continuous operation of the sponge pad 211 in different areas is changed alternately by the intermittent rotation of the rotating wheel 28, and the dust particles existing on the working surface of the sponge pad 211 after adsorption are dried and separated in the cleaning room 212 through the heating of the electric heating plate 213 and the interaction between the flexible roller brush 214 and the working surface of the sponge pad 211, and are pumped into the dust cylinder 216 through the air duct 215 and the conduit 217, so as to ensure the adsorption between the single sponge pad 211 and the dust particles on the surface of the electrode assembly 19, and complete the pre-treatment of dust removal on the surface of the electrode assembly 19; Step 3: Finally, the shovel plate 37 that moves synchronously with the knob plate constantly interacts with the dust on the surface of the electrode assembly 19 during movement. At the same time, the double openings 312 guide and adsorb the dust on the end surface of the shovel plate 37 and the area between the shovel plate 37 and the vertical fixing rod 18, thereby reducing the accumulation of dust on the surface of the electrode assembly 19. In addition, during specific implementation, by finely adjusting the rotation angle of the gland 44, the synchronous adjustment of the interaction degree between the scraper plate 37 and the surface of the electrode assembly 19 is realized. In this way, the step-by-step cleaning process of the dust deposited on the outer surface of the electrode assembly 19 by the scraper plate 37 is achieved, the friction force between the dust particles and the scraper plate 37 during a single cleaning is equalized, excessive rigid contact between the dust particles and the electrode assembly 19 is avoided, scratches are reduced, and the service life of the electrode assembly 19 is prolonged.
