Description

Technical Field

[0001] This invention relates to the field of electrode graphite felt preparation technology, and in particular to an activation treatment device and method for preparing electrode graphite felt. Background Technology

[0002] Electrode graphite felt is a material used in batteries, electrolytic cells and other fields. Its manufacturing process requires activation treatment to improve its electrochemical performance.

[0003] Currently, in the preparation of electrode graphite felt, it is often necessary to activate it by soaking in acid and alkali solutions. However, existing technologies generally only involve direct soaking, which has poor soaking effect and is prone to precipitation, affecting the soaking effect. In addition, before sintering the electrode graphite felt, existing technologies can sprinkle bismuth nitrate powder on the surface of the graphite felt. This not only oxidizes the felt surface, forming a nanoscale microporous structure and increasing the specific surface area, but also allows bismuth nitrate to decompose during activation, with the decomposition products depositing on the carbon felt surface for further modification. However, the current method of sprinkling bismuth nitrate powder is generally manual, which is not only labor-intensive but also results in poor uniformity. Therefore, it is of great significance to study a new activation treatment device and method for electrode graphite felt preparation to solve the above problems. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems mentioned above and / or existing electrode graphite felt preparation, the present invention is proposed.

[0006] Therefore, the technical problem to be solved by the present invention is that in the process of preparing electrode graphite felt, it is often necessary to soak it in acid and alkali solutions for activation treatment. In the prior art, it is generally just soaked directly, which has poor soaking effect. Moreover, acid and alkali solutions are prone to precipitation, which affects the soaking effect. Furthermore, the prior art generally uses manual spraying to sprinkle bismuth nitrate powder catalyst, which is not only labor-intensive but also has poor uniformity, making it difficult to achieve uniform spraying.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an activation treatment apparatus for preparing electrode graphite felt, comprising,

[0008] A graphite felt processing mechanism includes a box and a felt body passing through the box. A stirring assembly is installed on the left side inside the box. The front end of the stirring assembly is connected to a spiral spraying assembly. The upper part of the spiral spraying assembly is located near the felt body. A drying assembly is installed on the right side of the box.

[0009] A reciprocating material spreading mechanism includes a reciprocating motion component, which is fixed on a housing. The reciprocating motion component is connected to a mixing component via a belt drive structure. A material cylinder is connected to the reciprocating motion component via a bearing. A mixing and spreading component is provided through the material cylinder. The bottom of the mixing and spreading component is located above a felt body. A toothed rod is engaged with the top of the mixing and spreading component and is fixedly connected to the housing.

[0010] As a further aspect of the present invention: the interior of the box is rotatably connected to several guide rollers, and the felt body passes around several guide rollers.

[0011] As a further aspect of the present invention: the reciprocating motion assembly includes a roller body, which is rotatably connected to the housing via a bearing. An arc-shaped groove is provided on the roller body, and a drive rod is slidably connected in the arc-shaped groove. An I-shaped block is fixedly connected to one end of the drive rod away from the arc-shaped groove.

[0012] As a further aspect of the present invention: an opening is provided on the top of the box body, and the I-shaped block is slidably connected to the opening.

[0013] As a further aspect of the present invention: the material cylinder is rotatably connected to the I-shaped block via bearings, the material cylinder has a feed inlet at the top and several discharge outlets at the bottom.

[0014] As a further aspect of the present invention: the mixing and dispensing assembly includes a rotating rod, which is rotatably connected to the material cylinder via a bearing, and a gear is fixedly connected to the top end of the rotating rod, the gear meshing with a rack.

[0015] The rotating rod is externally fixedly connected to several stirring blades, which are located in the material cylinder;

[0016] The bottom end of the rotating rod is fixedly connected to a spraying disc, which is located above the felt body.

[0017] As a further aspect of the present invention: the stirring assembly includes a motor, both sides of the motor are fixedly connected to the housing via mounting bases, the output shaft of the motor is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected to the housing via bearings;

[0018] The rotating shaft is connected to the roller body via a belt drive structure, and three sets of stirring racks are fixedly connected to the rotating shaft, with the stirring racks located in the box.

[0019] As a further aspect of the present invention: the spiral spraying assembly includes a cylinder, the cylinder is fixedly connected to the housing, and one end of the rotating shaft passes through the cylinder and is fixedly connected to a spiral blade, the pitch of the spiral blade decreasing sequentially from back to front;

[0020] One side of the cylinder is connected to an infusion tube, and the end of the infusion tube away from the cylinder passes upward through the box and is connected to the flow equalization plate, which corresponds to the felt body.

[0021] As a further aspect of the present invention: the drying assembly includes a hot air blower, which is fixedly installed on the housing. The air outlet of the hot air blower is connected to a hot air head assembly through a connecting pipe. The hot air head assembly consists of three sets arranged longitudinally and corresponding to the felt body.

[0022] An activation treatment method for an activation treatment device used in the preparation of electrode graphite felt includes the following steps:

[0023] S1. When activating the felt body, the motor drives the rotating shaft to rotate, which in turn drives the stirring rack to rotate. The rotating rack stirs the acid and alkali solutions stored on the left side of the box, and the felt body is subjected to acid and alkali treatment in the acid and alkali solutions. The rotating shaft drives the spiral blade to rotate, and the spiral blade delivers the acid and alkali solutions into the cylinder. As the pitch of the spiral blade decreases in sequence, the spiral blade squeezes the liquid, causing the liquid to flow upward from the delivery pipe into the flow equalization plate. The flow equalization plate sprays the acid and alkali solutions onto the felt body, allowing the sprayed acid and alkali solutions to fully penetrate into the interior of the felt body.

[0024] S2. Secondly, during the rotation of the shaft, the belt drive structure is also driven to move. The belt drive structure drives the roller to rotate. The roller squeezes the drive rod through the arc groove, causing the drive rod to reciprocate along the arc groove. The drive rod drives the I-shaped block to reciprocate back and forth. The I-shaped block drives the material cylinder to move back and forth. The material cylinder drives the gear to move back and forth. The gear moves back and forth and meshes with the rack, causing the gear to rotate and drive the rotating rod to rotate. The rotating rod drives the stirring blade to agitate the bismuth nitrate powder to flow. The bismuth nitrate powder falls onto the spraying disc through the discharge port. The rotating rod drives the spraying disc to keep rotating, and the spraying disc centrifugally throws out the bismuth nitrate powder on the surface, causing the bismuth nitrate powder to adhere to the felt.

[0025] S3. Then, control the hot air blower to operate. The hot air blower heats and transports the airflow, so that the hot airflow is transported into the hot air head group through the connecting pipe. The hot air head group heats and dries the felt body through the nozzles, thereby completing the activation treatment of the felt body. After the activation treatment, the felt body is transferred out of the box.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. The activation treatment equipment and method for preparing electrode graphite felt involves a motor-driven rotating shaft that rotates a stirring frame, causing the stirring frame to agitate the acid and alkali solutions inside the chamber, preventing precipitation and maintaining a good soaking effect between the felt and the acid and alkali solutions. The rotating shaft also drives a spiral blade to rotate. Since the pitch of the spiral blades decreases sequentially, the spiral blades transport the acid and alkali solutions into a cylinder and compress and discharge them. The pressurized acid and alkali solutions are then fed into a delivery pipe and sprayed onto the felt through a flow equalization plate. The pressurized sprayed acid and alkali solutions can quickly penetrate the felt, increasing the permeability and thus improving the activation treatment quality of the felt. Furthermore, this pressurization and stirring process is integrated, eliminating the need for additional drive equipment and reducing costs.

[0028] 2. The activation treatment equipment and method for preparing electrode graphite felt uses a rotating shaft as the driving force to drive the belt drive structure to move. The belt drive structure drives the roller to rotate. The roller squeezes the drive rod through the arc groove to achieve reciprocating motion. The drive rod drives the cylinder to reciprocate through the I-shaped block. The cylinder drives the gear and the rack to mesh and drive the rotating rod to rotate. The stirring blade agitates the bismuth nitrate powder, thereby avoiding the bridging phenomenon of bismuth nitrate powder, which leads to the problem of difficult material feeding. Moreover, the bismuth nitrate powder can be discharged downward through the discharge port. The rotating rod drives the spraying disc to rotate, so that the spraying disc throws out the bismuth nitrate powder through centrifugal force, so that the bismuth nitrate powder is automatically sprayed on the felt for oxidation. Moreover, it can achieve uniform spraying.

[0029] 3. The activation treatment equipment and method for preparing electrode graphite felt utilizes a motor-driven rotating shaft to rotate a stirring frame, which agitates the acid and alkali solutions to maintain the soaking effect of the solutions on the felt. The spiral blades, with varying pitches, pressurize the acid and alkali solutions, allowing them to penetrate the felt better through a flow equalization plate, keeping the felt moist. Next, the rotating shaft drives a belt-driven structure to rotate a roller. The roller, through an arc-shaped groove, drives a drive rod in reciprocating motion, which in turn drives a cylindrical motion, causing a gear to mesh with a rack. This gear then drives a rotating rod to rotate, which in turn drives a spreading disc to evenly distribute bismuth nitrate powder onto the felt. This makes it easier for the moist felt to adhere to the bismuth nitrate powder, preventing the powder from easily falling off and causing waste, and increasing the difficulty of subsequent recycling. Therefore, this method improves the activation treatment effect and quality of the felt. Attached Figure Description

[0044] Example 1

[0045] like Figure 1-4 , Figure 8 and Figure 9As shown, the present invention provides a technical solution: an activation treatment device for preparing electrode graphite felt, including a graphite felt treatment mechanism 100, including a housing 101 and a felt body 102 passing through the housing 101. A plurality of guide rollers 104 are rotatably connected inside the housing 101. The guide rollers 104 can rotate around the felt body 102, allowing the felt body 102 to extend to the bottom of the housing 101, enabling the felt body 102 to be smoothly immersed in acid or alkali solutions. The felt body 102 passes around the guide rollers 104. A stirring assembly 106 is assembled on the left side inside the housing 101. The stirring assembly 106 includes a motor 106a. Both sides of the motor 106a are fixedly connected to the housing 101 via fixing seats, which maintain the motor 106a. The motor 106a is stably fixed, and the output shaft of the motor 106a is fixedly connected to the rotating shaft 106b. The rotating shaft 106b is rotatably connected to the housing 101 through bearings. The rotating shaft 106b can maintain stable rotational movement through the bearings. The rotating shaft 106b is connected to the roller 202a through the belt drive structure 107. The belt drive structure 107 can transmit power over long distances, thus smoothly driving the roller 202a to rotate. Three sets of stirring frames 106c are fixedly connected to the rotating shaft 106b. The stirring frames 106c can agitate the flow of acid and alkali solutions. The stirring frames 106c are located in the housing 101. The front end of the stirring assembly 106 is connected to the spiral spray assembly 108. The spiral spray assembly 108 includes a cylinder 108a. 08a is fixedly connected to the housing 101. The cylinder 108a can remain sealed, thus allowing the flow of acid and alkali solutions. One end of the rotating shaft 106b passes through the cylinder 108a and is fixedly connected to a spiral blade 108d. The pitch of the spiral blade 108d decreases sequentially from back to front. This sequential decrease in pitch allows the spiral blade 108d to not only transport acid and alkali solutions but also pressurize and discharge them, increasing the discharge force. One side of the cylinder 108a is connected to a delivery pipe 108b, which connects the cylinder 108a and the flow equalization plate 108c, thus transporting acid and alkali solutions. The end of the delivery pipe 108b away from the cylinder 108a passes upward through the housing 101 and connects to the flow equalization plate 108c. The flow equalization plate 108c corresponds to the felt body 102. The upper part of the spiral spraying component 108 is located near the felt body 102. A drying component 103 is installed on the right side of the box 101. The drying component 103 includes a hot air blower 103a, which is fixedly installed on the box 101. The air outlet of the hot air blower 103a is connected to the hot air head group 103b through the connecting pipe 103c. The hot air head group 103b consists of three groups arranged longitudinally and corresponding to the felt body 102. The hot air blower 103a sprays hot air through the hot air head group 103b and guides the felt body 102 multiple times through the guide roller 104, so that the felt body 102 and the hot air head group 103b are arranged alternately, thereby improving the drying effect of the felt body 102.

[0046] The reciprocating material spreading mechanism 200 includes a reciprocating motion component 202, which is fixed on the housing 101. The reciprocating motion component 202 is connected to the mixing component 106 via a belt drive structure 107. A material cylinder 203 is connected to the reciprocating motion component 202 via a bearing. A mixing and spreading component 205 is provided through the material cylinder 203. The bottom of the mixing and spreading component 205 is located above the felt body 102. A toothed rod 201 is engaged with the top of the mixing and spreading component 205 and is fixedly connected to the housing 101.

[0047] In this embodiment, the activation treatment equipment and method for preparing the electrode graphite felt uses a motor 106a to drive a rotating shaft 106b to rotate. The rotating shaft 106b drives a stirring frame 106c to rotate, causing the stirring frame 106c to agitate the acid and alkali solutions inside the tank 101, preventing the acid and alkali solutions from settling and thus maintaining a good soaking effect between the felt 102 and the acid and alkali solutions. Furthermore, the rotating shaft 106b also drives a spiral blade 108d to rotate. Because the pitch of the spiral blade 108d decreases sequentially, the spiral... The rotary blade 108d conveys the acid and alkali solution into the cylinder 108a and compresses and discharges the solution. The acid and alkali solution can then be pressurized and fed into the infusion pipe 108b, and sprayed onto the felt body 102 through the flow equalization plate 108c. The pressurized acid and alkali solution can quickly penetrate into the felt body 102, increasing the permeability and thus improving the activation quality of the felt body 102. Furthermore, this pressurization process is integrated with the stirring process, eliminating the need for additional drive equipment and reducing costs.

[0048] Example 2

[0049] Combined with appendix Figure 5-6 It is concluded that the reciprocating motion assembly 202 includes a roller body 202a, which is rotatably connected to the housing 101 via bearings. The roller body 202a can achieve stable rotation via bearings. An arc-shaped groove 202b is formed on the roller body 202a. The arc surface of the arc-shaped groove 202b can realize the movement of the extrusion drive rod 202c. The arc-shaped groove 202b is interconnected at both ends, so that the arc-shaped groove 202b can drive the drive rod 202c to reciprocate. The drive rod 202c is slidably connected in the arc-shaped groove 202b, and the end of the drive rod 202c away from the arc-shaped groove 202b is fixed. A fixed connection is provided with an I-shaped block 202d. An opening 105 is provided on the top of the housing 101. The I-shaped block 202d is slidably connected to the opening 105. The opening 105 allows the I-shaped block 202d to slide smoothly on the opening 105. The material cylinder 203 is rotatably connected to the I-shaped block 202d through a bearing. The material cylinder 203 can maintain smooth rotation through the bearing. A feed port is provided at the top of the material cylinder 203 to facilitate the feeding of bismuth nitrate powder. Several discharge ports 204 are provided at the bottom of the material cylinder 203 to facilitate the discharge of bismuth nitrate powder.

[0050] The mixing and spreading assembly 205 includes a rotating rod 205b, which is rotatably connected to the material cylinder 203 via bearings. The rotating rod 205b can maintain smooth rotation via bearings. A gear 205a is fixedly connected to the top of the rotating rod 205b, and the gear 205a meshes with the rack 201. Several stirring blades 205d are fixedly connected to the outside of the rotating rod 205b. The stirring blades 205d can agitate the bismuth nitrate powder to prevent the bismuth nitrate powder from bridging and failing to discharge. The stirring blades 205d are located in the material cylinder 203. A spreading disc 205c is fixedly connected to the bottom of the rotating rod 205b. The spreading disc 205c can spread the bismuth nitrate powder by centrifugation, thereby facilitating the spreading of the bismuth nitrate powder onto the felt body 102. The spreading disc 205c is located above the felt body 102.

[0051] In this embodiment: the belt drive structure 107 is driven by the rotating shaft 106b, which drives the roller 202a to rotate. The roller 202a compresses the drive rod 202c through the arc groove 202b to achieve reciprocating motion. The drive rod 202c drives the cylinder 108a to reciprocate through the I-shaped block 202d. The cylinder 108a drives the gear 205a to mesh with the rack 201, which in turn drives the rotating rod 205b to rotate. This causes the stirring blade 205d to agitate the bismuth nitrate powder, thus avoiding bridging of the bismuth nitrate powder and preventing difficulties in feeding. The bismuth nitrate powder can be discharged downward through the discharge port 204. The rotating rod 205b drives the spraying disc 205c to rotate, which centrifugally throws the bismuth nitrate powder out, allowing the bismuth nitrate powder to be automatically sprayed onto the felt body 102 for oxidation. This also achieves uniform spraying.

[0052] Example 3

[0053] Combined with appendix Figure 5-8 It is concluded that: the stirring assembly 106 includes a motor 106a, both sides of the motor 106a are fixedly connected to the housing 101 through fixed seats, the output shaft of the motor 106a is fixedly connected to a rotating shaft 106b, the rotating shaft 106b is rotatably connected to the housing 101 through bearings, the rotating shaft 106b is connected to the roller 202a through a belt drive structure 107, and three sets of stirring racks 106c are fixedly connected to the rotating shaft 106b, the stirring racks 106c are located in the housing 101;

[0054] The spiral spraying assembly 108 includes a cylinder 108a, which is fixedly connected to the housing 101. One end of the rotating shaft 106b passes through the cylinder 108a and is fixedly connected to a spiral blade 108d. The pitch of the spiral blade 108d decreases sequentially from back to front. One side of the cylinder 108a is connected to an infusion tube 108b. The end of the infusion tube 108b away from the cylinder 108a passes upward through the housing 101 and is connected to a flow equalization plate 108c. The flow equalization plate 108c corresponds to the felt body 102.

[0055] The reciprocating motion assembly 202 includes a roller body 202a, which is rotatably connected to the housing 101 via bearings. An arc-shaped groove 202b is provided on the roller body 202a. A drive rod 202c is slidably connected in the arc-shaped groove 202b. An I-shaped block 202d is fixedly connected to one end of the drive rod 202c away from the arc-shaped groove 202b. An opening 105 is provided on the top of the housing 101. The I-shaped block 202d is slidably connected to the opening 105. A material cylinder 203 is rotatably connected to the I-shaped block 202d via bearings. A feed inlet is provided on the top of the material cylinder 203. Several discharge outlets 204 are provided on the bottom of the material cylinder 203.

[0056] The mixing and spreading assembly 205 includes a rotating rod 205b, which is rotatably connected to the material cylinder 203 via a bearing. A gear 205a is fixedly connected to the top of the rotating rod 205b, and the gear 205a meshes with the rack 201. Several mixing blades 205d are fixedly connected to the outside of the rotating rod 205b, and the mixing blades 205d are located in the material cylinder 203. A spreading disc 205c is fixedly connected to the bottom of the rotating rod 205b, and the spreading disc 205c is located above the felt body 102.

[0057] In this embodiment: the motor 106a drives the rotating shaft 106b to rotate the stirring frame 106c, causing the stirring frame 106c to agitate the acid and alkali solutions and maintain the soaking effect of the acid and alkali solutions on the felt body 102. Furthermore, the spiral blades 108d pressurize the acid and alkali solutions through different pitches, allowing the pressurized solutions to better penetrate the felt body 102 through the flow equalization plate 108c, thus keeping the felt body 102 moist. Next, the rotating shaft 106b drives the belt drive structure 107 to rotate the roller 202a. The roller 202a rotates through the arc groove 202b. When rod 202c reciprocates, the I-shaped block 202d drives the cylinder 108a to move, which in turn drives gear 205a to mesh with rack 201. Gear 205a drives rotating rod 205b to rotate, and rotating rod 205b drives spreading disc 205c to evenly spread bismuth nitrate powder onto felt 102. This makes it easier for the wet felt 102 to adhere to the bismuth nitrate powder, avoiding the waste caused by the bismuth nitrate powder not adhering easily and falling off, and increasing the difficulty of subsequent recycling. Therefore, this method can improve the activation treatment effect of felt 102 and improve the activation treatment quality of felt 102.

[0058] An activation treatment method for an activation treatment device used in the preparation of electrode graphite felt includes the following steps:

[0059] S1. When activating the felt body 102, the motor 106a drives the rotating shaft 106b to rotate, the rotating shaft 106b drives the stirring rack 106c to rotate, the stirring rack 106c rotates to stir the acid and alkali solution stored on the left side of the box 101, and the felt body 102 is in the acid and alkali solution for acid and alkali treatment, and the rotating shaft 106b drives the spiral blade 108d to rotate, the spiral blade 108d conveys the acid and alkali solution into the cylinder 108a. As the pitch of the spiral blade 108d decreases in sequence, the spiral blade 108d squeezes the liquid, so that the liquid enters the flow equalization plate 108c from the infusion pipe 108b upwards. The flow equalization plate 108c sprays the acid and alkali solution onto the felt body 102, so that the sprayed acid and alkali solution fully penetrates into the interior of the felt body 102.

[0060] S2. Secondly, during the rotation of the rotating shaft 106b, the belt drive structure 107 is also driven to move. The belt drive structure 107 drives the roller 202a to rotate. The roller 202a squeezes the drive rod 202c through the arc groove 202b, causing the drive rod 202c to reciprocate along the arc groove 202b. The drive rod 202c drives the I-shaped block 202d to reciprocate, the I-shaped block 202d drives the material cylinder 203 to move back and forth, and the material cylinder 203 drives the gear 2... 05a moves back and forth, gear 205a moves back and forth and keeps meshing with rack 201, causing gear 205a to rotate and drive rotating rod 205b to rotate. Rotating rod 205b drives stirring blade 205d to stir bismuth nitrate powder to flow, and bismuth nitrate powder falls onto sprinkling disc 205c through discharge port 204. Rotating rod 205b drives sprinkling disc 205c to keep rotating, so sprinkling disc 205c centrifugally throws out bismuth nitrate powder on the surface, so that bismuth nitrate powder adheres to felt 102.

[0061] S3. Then, the hot air blower 103a is controlled to run. The hot air blower 103a heats and transports the airflow, so that the hot airflow is transported into the hot air head group 103b through the connecting pipe 103c. The hot air head group 103b heats and dries the felt body 102 through the nozzle diversion, thereby completing the activation treatment of the felt body 102. After the activation treatment, the felt body 102 is transferred out from the box 101.
