A sealing plate 41 is fixed to the flange 4. When the sealing plate 41 is opened, the material after stirring can be discharged from the discharge port.

[0042] The above stirring shaft 3 penetrates into the kettle body 1, and a stirring paddle 31 is fixedly connected to the middle of the stirring shaft 3. The stirring paddle 31 comprises a lower rotating part 311 and an upper rotating part 312. The upper rotating part 312 and the lower rotating part 311 are spaced apart and uniformly distributed along the axis of the stirring shaft 3, and each of the upper rotating part 312 and the lower rotating part 311 has two. The stirring part on the lower rotating part 311 faces away from the power component 2, and the stirring part on the upper rotating part 312 faces the power component 2.

[0043] After the explosion-proof variable frequency motor 21 is started, the stirring shaft 3 rotates, and the stirring paddle 31 rotates synchronously with the stirring shaft 3. The upper rotating part 312 conducts the electrolyte material upward, and the lower rotating part 311 conducts the electrolyte material downward.

[0044] A plurality of baffles 5 are fixed to the inner wall of the kettle body 1 and arranged opposite to the stirring paddle 31. The baffles 5 are three in total and uniformly arranged along the axis of the kettle body 1, and the baffles 5 are vertically placed. The above first temperature gauge 161 is located below the baffles 5.

[0045] The baffle 5 is provided with a first buffer part 51, a shearing part 52, an extrusion part 53 and a second buffer part 54 from top to bottom on one side of the kettle body 1. The first buffer part 51 is in U shape and the upper end is fixedly connected with the inner wall of the kettle body 1, that is, the first buffer part 51 is arranged in concave. The shearing part 52 is arranged in U shape and communicates with the first buffer part 51, and the shearing part 52 has a shearing gap with the kettle body 1, that is, the shearing part 52 is arranged in convex. The extrusion part 53 is in U shape and the upper end communicates with the lower end of the shearing part 52, and the lower end of the extrusion part 53 is fixedly connected with the inner wall of the kettle body 1. The second buffer part 54 is in U shape and the upper and lower ends are fixedly connected with the inner wall of the kettle body 1. The extrusion part 53 and the second buffer part 54 are also arranged in concave.

[0046] The concave amplitude of the extrusion part 53 is the largest, the concave amplitude of the second buffer part 54 is the second, and the concave amplitude of the first buffer part 51 is the smallest. The first buffer part 51, the shearing part 52, the extrusion part 53 and the second buffer part 54 are arranged in wave shape as a whole.

[0047] The lower end of the stirring shaft 3 is fixedly connected with an arc-shaped stirring plate 6, and the middle part of the arc-shaped stirring plate 6 is fixedly connected with the stirring shaft 3. Five stirring blocks 61 are fixedly connected to the side of the arc-shaped stirring plate 6 opposite to the stirring shaft 3. With the center of the arc-shaped stirring plate 6 as a boundary line, three stirring blocks 61 are arranged on one side of the boundary line and two stirring blocks 61 are arranged on the other side of the boundary line.

[0048] The steam passes through the upper thin film regulating valve to adjust the flow, passes through the Y-shaped filter, and obtains the pressure value from the inlet, and obtains the temperature measured by the temperature transmitter at the end.

[0049] The temperature in the kettle body 1 is obtained by the temperature transmitter at the lower right part and the upper part of the kettle cover 12, and is connected to the PLC system to transmit the command to the regulating valve to adjust the steam flow to control.

[0050] The clear water passes through the bottom thin film regulating valve to adjust the flow, and the pressure at the inlet and the upper outlet is obtained by the pressure transmitter and the flow is obtained by the flow transmitter from the PLC system.

[0051] The temperature in the kettle body 1 is obtained by the temperature transmitter at the lower right part and the upper part of the kettle cover 12, and is connected to the PLC system to transmit the command to the regulating valve to adjust the steam flow to control.

[0052] The embodiment 2 is different from the embodiment 1 in that the cleaning structure of the inner wall of the kettle body 1. A fixed disc 71 is fixedly connected to the upper end of the stirring shaft 3, and a rotating ring 72 is sleeved outside the fixed disc 71, and the fixed disc 71, the stirring shaft 3 and the rotating ring 72 are coaxially arranged. The rotating ring 72 is rotatably connected to the stirring shaft 3 through a bearing 721. The bearing 721 is provided with damping grease. A pin shaft 73 is fixedly connected to the rotating ring 72, a clamping plate 74 is rotatably connected to the pin shaft 73, and a first spring 75 is fixedly connected between the clamping plate 74 and the rotating ring 72. A blocking column 76 is fixedly connected to the rotating ring 72 and located on one side of the clamping plate 74. A clamping block 711 with a triangular cross section is fixedly connected to the outer circular face of the fixed disc 71, and a plurality of clamping blocks 711 are uniformly arranged along the axis of the fixed disc 71. The clamping plate 74 is embedded in the gap between two clamping blocks 711 through the elastic force of the spring, and at this time, the clamping plate 74 is in an inclined state with the fixed disc 71. When the stirring shaft 3 drives the stirring paddle 31 to rotate forward, the clamping plate 74 slides along the long side of the clamping block 711 to the outside of the fixed disc 71, and the clamping plate 74 is separated from the gap and cannot rotate synchronously with the fixed disc 71. When the stirring shaft 3 drives the stirring paddle 31 to rotate reversely, the clamping plate 74 slides along the long side of the clamping block 711 to the inside of the fixed disc 71, so that the clamping plate 74 is clamped in the gap between the two clamping blocks 711, thereby enabling the rotating ring 72 to rotate synchronously with the fixed disc 71.

[0053] Based on this, a fixed tube 81 is fixedly connected to the outer wall of the rotating ring 72, the fixed tube 81 is arranged along the radial direction of the rotating ring 72, an extension tube 82 is arranged in the fixed tube 81, and a sliding rod 83 is arranged in the extension tube 82. A first positioning ring 84 is fixedly connected to the outer wall of one end of the extension tube 82 close to the fixed tube 81. A second positioning ring 85 is fixedly connected to the inner wall of the end of the fixed tube 81 for abutting against the first positioning ring 84. A third positioning ring 86 is fixedly connected to the outer wall of one end of the sliding rod 83 close to the extension tube 82. A fourth positioning ring 87 is fixedly connected to the inner wall of one end of the extension tube 82 close to the sliding rod 83 for abutting against the third positioning ring 86. A sealing ring 88 is fixedly connected to the outer wall of one end of the sliding rod 83 away from the fixed tube 81, and the sealing ring 88 is used for abutting against the end of the fixed tube 81. A second spring 89 is fixedly connected between the bottom wall of the fixed tube 81 and the sliding rod 83.

[0054] The inner wall of the fixed tube 81, the inner wall of the extension tube 82 and the sliding rod 83 are all square in cross section.

[0055] A discharge hole 811 is defined at the end of the fixed tube 81 near the rotating ring 72. This hole 811 communicates with the inner wall of the fixed tube 81 and is radially disposed along the fixed tube 81. A small amount of material enters the fixed tube 81 through the gap between the fixed tube 81 and the slide bar 83. Due to the elastic force of the second spring 89, the slide bar 83 slides along the fixed tube 81, squeezing the material out of the discharge hole 811. A scraper 9 is fixedly attached to the end of the slide bar 83 away from the fixed tube 81. The scraper 9 extends along the length of the kettle body 1. Fences 91 are located on either side of the scraper 9, forming a U-shaped structure between the guards 91 and the scraper 9.

[0056] This structure allows the scraper 9 to be kept as close to the agitator shaft 3 as possible under the elastic force of the second spring 89, and the fixed tube 81 can be located within the guard plate 91. During the stirring of the material by the agitator paddle 31, the material is protected by the guard plate 91, preventing it from splashing onto the fixed tube 81. Furthermore, since the liquid level of the swirling material is lower near the agitator shaft 3 and higher near the kettle body 1, the scraper 9 as a whole is less likely to be drawn into the swirling material. This improves the protection of the scraper 9 while allowing it to be as long as possible.

[0057] The stirring shaft 3 rotates forward, thoroughly stirring and mixing the material. After opening the sealing plate 41, the material is discharged from the kettle body 1. Subsequently, the stirring shaft 3 is rotated in the reverse direction, and the rotating ring 72 rotates synchronously with the fixed plate 71. Centrifugal force overcomes the elastic force of the second spring 89, and the extension tube 82 extends from the fixed tube 81. The slide rod 83 extends from the extension tube 82, causing the scraper 9 to contact the inner wall of the kettle body 1. In combination with the clean water or cleaning liquid introduced into the kettle body 1 from the spray head 13, the scraper 9 scrapes the material off the inner wall of the kettle body 1.

[0058] In order to improve the efficiency of scraping materials, a discharge trough 90 with a V-shaped cross-section is opened at the end of the scraper 9. The discharge trough 90 is arranged along the length direction of the scraper 9 so that the material can fall quickly along the discharge trough 90.

[0059] The lower end of the discharge chute 90 is located above the baffle 5 , and an inclined discharge chute 901 is provided at the lower end of the discharge chute 90 to increase the discharge speed and to conduct the clean water on the inner wall of the kettle body 1 downward to flush the baffle 5 .

[0060] A spray hole 92 is defined at the lower end of the agitator shaft 3. This hole is located above the curved agitator plate 6 and at the same height as the baffle 5. A feed plate 93 is fixedly attached to the outer wall of the agitator shaft 3, positioned to one side of the spray hole 92. A groove 94 is defined on the surface of the feed plate 93, with its end corresponding to the spray hole 92. The cross-section of the spray hole 92 is trapezoidal, with the opening of the spray hole 92 closer to the feed plate 93 being larger than the opening farther from the feed plate 93.

[0061] Accordingly, during the rotation of the stirring shaft 3, the feeding plate 93 rotates synchronously with the stirring shaft 3, and the material enters the spray hole 92 from the groove 94. Since the material has a large momentum when entering the spray hole 92, the flow rate of the material is increased when it is extruded from the spray hole 92, so that the material is rapidly conducted from the middle of the vortex to the edge of the vortex, and the material can pass through the baffle 5 again to achieve further sufficient stirring and extrusion of the material.

[0062] Thus, during the stirring of the material, the material can be conducted from the middle of the vortex to the edge of the vortex, and the material can be conducted from the edge of the vortex to the middle of the vortex with the rotation of the stirring paddle 31. At the same time, with the rotation of the lower rotating part 311 and the upper rotating part 312 on the stirring paddle 31, the material close to the stirring paddle 31 can be conducted upward and downward, so that the material can be conducted from inside to outside, from outside to inside, from bottom to top, and from top to bottom at the same time, greatly improving the stirring effect.

[0063] Finally, the support frame 100 is hinged to the lower end of the scraper 9, and the impact plate 101 is fixedly connected in the support frame 100. The middle part of the impact plate 101 has a protruding part 102 for abutting against the baffle 5.

[0064] During the cleaning of the kettle body 1, the stirring shaft 3 rotates in the opposite direction, the scraper 9 moves towards the inner wall of the kettle body 1, the protruding part 102 abuts against the baffle 5, and then the support frame 100 rotates around the hinge and passes through the baffle 5. During this period, the baffle 5 vibrates to shake off the material in the first buffer part 51, the shear part 52, the extrusion part 53, and the second buffer part 54, improving the cleaning effect. The impact plate 101 has strong impact resistance and is not easy to break.

[0065] Of course, the above is only a typical example of the present application, in addition to which the present application can have other various specific embodiments, and any technical solution formed by equivalent substitution or equivalent transformation falls within the scope of the present application.
