Description

Technical Field

[0001] The present invention relates to the technical field of reaction kettles, and particularly to a stirring device for an enamel reaction kettle. Background Art

[0002] Enamel is a special chemical equipment material, composed of a layer of glass and an enamel coating, with advantages such as corrosion resistance, high temperature resistance, and wear resistance. It is widely used in fields such as chemical industry, pharmaceuticals, and food. Enamel stirring is usually achieved by adding a stirrer to an enamel reaction kettle or an enamel reaction tank, and through the agitation of the stirrer, the mixing, homogenization, dissolution, reaction, etc. of liquid or solid materials are realized.

[0003] A Chinese patent document with the publication number CN117531467B discloses an enamel stirrer, which includes a driving motor, a reciprocating lead screw arranged below the driving motor, and a first limit block at the end of the reciprocating lead screw; a stirring mechanism, which includes a connecting component arranged on the reciprocating lead screw, a clamping component arranged at the top of the connecting component, and two groups of stirring components symmetrically arranged on both sides of the connecting component; a limiting mechanism, which includes a limiting component located below the driving motor.

[0004] When the above-mentioned enamel stirrer in the prior art is in use, the stirring mechanism is limited on the driving motor by setting a limiting mechanism, so that the stirring mechanism can perform reciprocating up and down movements in the vertical direction on the driving motor, making the stirring position of the device no longer limited to the lower part of the reaction kettle, but distributed and operating throughout the reaction kettle. And there are stirring components on both sides of the stirring mechanism that can follow the up and down movement of the stirring mechanism and perform self-rotating stirring. The self-rotation stirring of the stirring components cooperates with the up and down displacement stirring of the whole stirring mechanism.

[0005] However, the following deficiencies still exist in the above-mentioned prior art: When in use, after the liquid material and the solid material are sequentially put into the enamel reaction kettle, the stirring device stirs and mixes the liquid material and the solid material. At this time, the solid material will move due to the flow of the liquid material, and the solid material is prone to impact the enamel coating on the inner wall of the enamel reaction kettle during the moving process, thereby causing damage to the enamel coating. Summary of the Invention

[0006] The present invention provides a stirring device for an enamel reaction kettle, aiming to solve the problem that the enamel coating on the inner wall of the enamel reaction kettle is easily damaged by the impact of solid materials during the moving process in the related art.

[0007] The stirring device of the glass-lined reactor of the present invention includes a reactor and a stirring mechanism. The stirring mechanism includes a rotating shaft and a stirring part. The stirring part is connected to the rotating shaft, and the rotating shaft can rotate. It also includes an opening and closing mechanism. The opening and closing mechanism includes a moving frame, a connecting arm, a fixing part, an opening and closing part, and an elastic part three. The moving frame is rotatably connected to the rotating shaft through the connecting arm. The fixing part is connected to the stirring part. Both the opening and closing part and the elastic part three are provided in two. The two opening and closing parts are respectively connected to the moving frame through the two elastic parts three. The moving frame can tilt upward to make the two opening and closing parts move away from each other under the block of the fixing part. The moving frame can also tilt downward to make the two opening and closing parts approach each other under the action of the two elastic parts three.

[0008] Beneficial effects: When the moving frame tilts upward, the two opening and closing parts contact the fixing part, and the two opening and closing parts move away from each other under the guiding block of the fixing part, so that the two opening and closing parts are in an open state and stretch the two elastic parts three. When the moving frame tilts downward, the two opening and closing parts move along the surface of the fixing part driven by the two elastic parts three until the two opening and closing parts are reset. After resetting, the two opening and closing parts can contact the enamel coating, so that when the rotating shaft drives the opening and closing mechanism to move along a circular track, the two opening and closing parts can scrape the solid materials on the surface of the enamel coating. It can be seen that through the reciprocating tilting movement of the moving frame up and down, the two opening and closing parts can be continuously opened and closed, so as to disturb the liquid materials close to the enamel coating and form a buffer area to avoid large impacts on the enamel coating caused by solid materials.

[0009] Preferably, two inclined surfaces are provided on the fixing part, and the two opening and closing parts are respectively in contact with the two inclined surfaces.

[0010] The effect is that: through the two inclined surfaces on the fixing part, the movement of the two opening and closing parts can be guided to facilitate the opening and closing operation of the two opening and closing parts.

[0011] Preferably, it further includes a feeding mechanism. The feeding mechanism includes a driving part and a feeding part. The driving part can drive the feeding part to feed the solid materials.

[0012] Preferably, the driving part includes a connecting shaft, a protruding part, a toothed plate, an elastic part two, and a guiding part. The rotating shaft is hollow, and a plurality of openings communicating with its interior are provided on the outer side of the rotating shaft. The connecting shaft is inserted into the rotating shaft. The protruding part is connected to the connecting shaft and penetrates through the opening on the rotating shaft. The guiding part is connected to the mounting seat. The elastic part two is connected between the bottom of the connecting shaft and the inner bottom wall of the rotating shaft. The toothed plate is connected to the connecting shaft.

[0013] The effect is that: when the rotating shaft rotates, it can push the protruding part to drive the connecting shaft to rotate, and the protruding part can move upward under the guiding of the guiding part, so that the connecting shaft can move upward while rotating. The upward movement of the connecting shaft can drive the toothed plate to move upward, so that the toothed plate drives the feeding part to feed the solid materials.

[0014] Preferably, the feeding member includes a connecting plate, a material leakage plate, a blocking plate and a first elastic part. There are two connecting plates and two material leakage plates. The two connecting plates and the two material leakage plates are both connected in the opening outside the rotating shaft. The two connecting plates and the two material leakage plates are both meshed and connected with the toothed plate. There are two blocking plates. The two blocking plates are respectively connected in a limit sliding manner at the bottoms of the two material leakage plates. The first elastic part is connected between the blocking plate and the material leakage plate.

[0015] The effect is that: the toothed plate can drive the two connecting plates and the two material leakage plates to turn up or down simultaneously. When the two connecting plates and the two material leakage plates turn down simultaneously, the connecting plate can push the blocking plate on the material leakage plate, so that the blocking plate no longer blocks the material leakage holes on the material leakage plate, thereby realizing the uniform feeding of solid materials and enhancing the mixing effect of liquid materials and solid materials.

[0016] Preferably, the two connecting plates and the two material leakage plates are arranged alternately in a ring shape.

[0017] Preferably, one sides of the two connecting plates and the two material leakage plates close to the connecting shaft are all arc-shaped, and tooth parts are arranged on one sides of the two connecting plates and the two material leakage plates close to the connecting shaft. The tooth parts on the two connecting plates and the two material leakage plates are all meshed and connected with the toothed plate.

[0018] The effect is that: through the tooth parts on the two connecting plates and the two material leakage plates, when the toothed plate moves up and down, it can drive the two connecting plates and the two material leakage plates to turn up or down simultaneously.

[0019] Preferably, arc-shaped protrusions are arranged on one sides of the tops of the connecting plate and the material leakage plate far from the rotating shaft.

[0020] The effect is that: through the arc-shaped protrusions on the top edges of the connecting plate and the material leakage plate, when the connecting plate and the material leakage plate move along a circular track, solid materials can be prevented from separating from the connecting plate and the material leakage plate and impacting the enamel coating.

[0021] Preferably, the two connecting plates and the two material leakage plates have a conical state and a horizontal state. When the two connecting plates and the two material leakage plates are in the conical state, a material holding cavity can be formed for holding solid materials.

[0022] Preferably, the stirring part includes a sleeve rod, a plug rod and a spring. The sleeve rod is connected to the rotating shaft. The plug rod is inserted at one end of the sleeve rod far from the rotating shaft. The spring is installed in the sleeve rod and is in contact with the plug rod. One end of the plug rod extending out of the sleeve rod is threadedly connected to the fixing part.

[0023] The beneficial effects of the present invention are: 1. When the moving frame tilts and moves upward, the two opening and closing parts come into contact with the fixed part. Under the blocking and guiding of the fixed part, the two opening and closing parts move away from each other, so that the two opening and closing parts are in an open state, and the two elastic parts three are stretched. When the moving frame tilts and moves downward, the two opening and closing parts move along the surface of the fixed part driven by the two elastic parts three until the two opening and closing parts are reset. After reset, the two opening and closing parts can contact the enamel coating, so that when the rotating shaft drives the opening and closing mechanism to move along a circular track, the two opening and closing parts can scrape the solid materials on the surface of the enamel coating. It can be seen that by tilting the moving frame up and down reciprocally, the two opening and closing parts can be continuously opened and closed, so as to disturb the liquid materials near the enamel coating and form a buffer area to avoid large impacts on the enamel coating caused by solid materials.

[0024] 2. The toothed plate can drive the two connecting plates and the two material leakage plates to flip upward or downward simultaneously. When the two connecting plates and the two material leakage plates flip upward simultaneously, the two connecting plates and the two material leakage plates can form a conical state and form a material holding cavity. At this time, the blocking plate blocks the material leakage holes on the material leakage plates, so as to hold the solid materials. When the two connecting plates and the two material leakage plates flip downward simultaneously, the connecting plate can push the blocking plate on the material leakage plate, so that the blocking plate no longer blocks the material leakage holes on the material leakage plates, thus realizing the uniform discharging of solid materials, enhancing the mixing effect of liquid materials and solid materials. At the same time, by switching between the conical state and the horizontal state of the two connecting plates and the two material leakage plates, the solid materials can be turned over to avoid blocking the material leakage holes.

Detailed implementation manners

[0040] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0041] As Figures 1 to 14As shown in the figure, the stirring device of the glass-lined reactor of the present invention includes a reactor 1, a stirring mechanism 2, a feeding mechanism 3 and an opening and closing mechanism 4. The reactor 1 is used to contain liquid materials and solid materials. The stirring mechanism 2 is connected inside the reactor 1 and is used to stir the liquid materials and solid materials in the reactor 1 so that the liquid materials and solid materials are mixed and reacted. The feeding mechanism 3 is connected to the stirring mechanism 2 and the feeding mechanism 3 is located inside the opening and closing mechanism 4 and is used to evenly feed the solid materials to accelerate the mixing and reaction efficiency of the liquid materials and solid materials. The opening and closing mechanism 4 is connected between the stirring mechanism 2 and the feeding mechanism 3. The opening and closing mechanism 4 can disturb the liquid materials close to the enamel coating and form a buffer area to avoid large impacts on the enamel coating caused by solid materials.

[0042] As Figure 1 shown, the reactor 1 includes a lower reactor body 11, an upper reactor body 12 and a mounting seat 13. The upper reactor body 12 is connected to the top of the lower reactor body 11. A reaction chamber for containing liquid materials and solid materials can be formed between the lower reactor body 11 and the upper reactor body 12 for the liquid materials and solid materials to be mixed and reacted. The mounting seat 13 is connected to the top of the upper reactor body 12 and is used to support and install the stirring mechanism 2. A feeding channel is connected to the top of the upper reactor body 12 to facilitate the transportation of liquid materials and solid materials into the reaction chamber.

[0043] As Figure 1 and Figure 2 shown, the stirring mechanism 2 includes a driving source 21, a rotating shaft 22 and a stirring part 23. The driving source 21 is a motor with a telescopic end facing downwards. The driving source 21 is connected to the mounting seat 13. The rotating shaft 22 is connected to the output shaft of the driving source 21. The rotating shaft 22 is rotatably connected to the mounting seat 13. The stirring part 23 is provided in four groups, and the number of each group of stirring parts 23 is set to be multiple. The four groups of stirring parts 23 are all connected to the rotating shaft 22.

[0044] Start the driving source 21 to drive the rotating shaft 22 to rotate. Through the rotating shaft 22, the four groups of stirring parts 23 can be driven to move along a circular track, so as to stir the liquid materials and solid materials in the reaction chamber, thereby accelerating the mixing and reaction efficiency of the liquid materials and solid materials.

[0045] As Figures 2 to 6 , Figures 9 to 14As shown, the feeding mechanism 3 includes a driving member and a feeding member. The driving member can drive the feeding member to evenly feed the solid material, thereby accelerating the mixing reaction efficiency of the liquid material and the solid material. The driving member includes a connecting shaft 31, a protruding portion 32, a toothed plate 36, a second elastic portion 38, and a guiding portion 39. The rotating shaft 22 is hollow, and a plurality of openings 221 communicating with its interior are provided on the outer side of the rotating shaft 22. The connecting shaft 31 is inserted into the rotating shaft 22, and the protruding portion 32 is connected to the connecting shaft 31 and passes through the opening 221 on the rotating shaft 22. The connecting shaft 31 can be limited by the protruding portion 32, so that when the rotating shaft 22 rotates, it can drive the connecting shaft 31 to rotate coaxially and in the same direction by pushing the protruding portion 32. The guiding portion 39 is connected to the mounting seat 13. When the connecting shaft 31 rotates, the protruding portion 32 can be guided by the guiding portion 39, so that the protruding portion 32 drives the connecting shaft 31 to move upward. The second elastic portion 38 is connected between the bottom of the connecting shaft 31 and the inner bottom wall of the rotating shaft 22. The second elastic portion 38 is a spring, and the second elastic portion 38 can drive the connecting shaft 31 and the protruding portion 32 to move downward and reset after the protruding portion 32 disengages from the guiding portion 39. The toothed plate 36 is connected to the connecting shaft 31. When the connecting shaft 31 moves up and down, it can drive the toothed plate 36 to move up and down, and the toothed plate 36 drives the feeding member to evenly feed the solid material.

[0046] Continue to refer to Figures 2 to 6 、 Figures 9 to 14As shown in the figure, the discharging member includes a connecting plate 33, a material leakage plate 34, a blocking plate 35 and a first elastic part 37. There are two connecting plates 33 and two material leakage plates 34. The two connecting plates 33 and the two material leakage plates 34 are arranged alternately in a ring shape. The two connecting plates 33 and the two material leakage plates 34 are both connected in the opening 221 outside the rotating shaft 22. The sides of the two connecting plates 33 and the two material leakage plates 34 close to the connecting shaft 31 are all arc-shaped, and tooth parts are provided on the sides of the two connecting plates 33 and the two material leakage plates 34 close to the connecting shaft 31. The tooth parts on the two connecting plates 33 and the two material leakage plates 34 are all meshed and connected with the toothed plate 36. When the connecting shaft 31 moves up and down, it can drive the toothed plate 36 to move up and down. By the up and down movement of the toothed plate 36, the two connecting plates 33 and the two material leakage plates 34 can be driven to turn up or down simultaneously. The two connecting plates 33 and the two material leakage plates 34 can turn up into a conical state to form a material storage cavity. The two connecting plates 33 and the two material leakage plates 34 can also turn down into a horizontal state. There are two blocking plates 35. The two blocking plates 35 are respectively connected in a limited sliding manner at the bottoms of the two material leakage plates 34. The material leakage plate 34 is provided with material leakage holes. The first elastic part 37 is connected between the blocking plate 35 and the material leakage plate 34. When the two connecting plates 33 and the two material leakage plates 34 turn up into a conical state, the first elastic part 37 is in a relaxed state. At this time, under the positioning action of the first elastic part 37, the blocking plate 35 blocks the material leakage holes on the material leakage plate 34. During the process of the two connecting plates 33 and the two material leakage plates 34 turning into a horizontal state, the connecting plate 33 can squeeze the blocking plate 35, so that the blocking plate 35 slides on the material leakage plate 34 and squeezes the first elastic part 37, thereby gradually opening the material leakage holes on the material leakage plate 34. At this time, the solid material can pass through the material leakage holes on the material leakage plate 34 and fall into the liquid material in the reaction cavity. By continuously switching between the conical state and the horizontal state of the two connecting plates 33 and the two material leakage plates 34, the material can be evenly transported into the liquid material in the reaction cavity to improve the mixing reaction efficiency of the liquid material and the solid material.

[0047] When opening the material leakage holes on the material leakage plate 34, the two connecting plates 33 and the two material leakage plates 34 turn from the conical state to the horizontal state. At this time, the two connecting plates 33 respectively push the two blocking plates 35, that is, each connecting plate 33 can only push one blocking plate 35, so that the two blocking plates 35 both move to open the material leakage holes on the two material leakage plates 34. And after the two connecting plates 33 and the two material leakage plates 34 are converted into the horizontal state, the top sides of the two connecting plates 33 pushing the two blocking plates 35 are respectively in contact with the bottoms of the two material leakage plates 34 corresponding to the two blocking plates 35, while the other sides of the tops of the two connecting plates 33 are not in contact with the bottoms of the adjacent two material leakage plates 34, and the side surfaces of the connecting plate 33 adjacent to the other side of its top and the side surfaces of the adjacent material leakage plate 34 are on the same plane, thus reserving enough space for the movement of the blocking plate 35.

[0048] The connecting plate 33 is located below the material leakage plate 34. The toothed plates 36 are divided into two groups, namely the first toothed group and the second toothed group. The number of toothed plates 36 in both the first toothed group and the second toothed group is set to two. The first toothed group and the second toothed group can be respectively meshed and connected with two material leakage plates 34 and two connecting plates 33. The bottoms of the two toothed plates 36 in the second toothed group are higher than the bottoms of the two toothed plates 36 in the first toothed group. The tops of the two toothed plates 36 in the first toothed group are flush with the tops of the two toothed plates 36 in the second toothed group. When the connecting shaft 31 moves downward to drive the first toothed group and the second toothed group to move downward, since the connecting plate 33 is located below the material leakage plate 34 and the bottoms of the two toothed plates 36 in the second toothed group are higher than the bottoms of the two toothed plates 36 in the first toothed group, the two toothed plates 36 in the first toothed group first mesh and drive with the two material leakage plates 34 to cause the two material leakage plates 34 to flip upward. When the two toothed plates 36 in the second toothed group move downward and are respectively meshed and driven with the connecting plate 33, the two connecting plates 33 are then driven to flip upward. When the connecting shaft 31 moves downward to drive the first toothed group and the second toothed group to move upward, the first toothed group and the second toothed group are synchronously meshed and driven with the two material leakage plates 34 and the two connecting plates 33. Since the bottoms of the two toothed plates 36 in the second toothed group are higher than the bottoms of the two toothed plates 36 in the first toothed group, the second toothed group first separates from the two connecting plates 33 and makes the connecting plate 33 in a horizontal state. Subsequently, the first toothed group continues to be meshed and driven with the two material leakage plates 34. Blocked by the edge of the connecting plate 33 near the edge of the blocking plate 35 at the top, the bottom of the blocking plate 35 near the edge of the connecting plate 33 will be resisted, thereby pushing the blocking plate 35 and squeezing the first elastic part 37 until the leakage holes on the material leakage plate 34 are opened and the material leakage plate 34 is in a horizontal state, so as to discharge materials.

[0049] Continue to refer to Figures 2 to 6 、 Figures 9 to 14 As shown, arc-shaped protrusions are provided on one side of the tops of the connecting plate 33 and the material leakage plate 34 away from the rotating shaft 22 to prevent the solid materials from directly impacting the enamel coating under the action of centrifugal force when the connecting plate 33 and the material leakage plate 34 are driven to rotate by the rotating shaft 22.

[0050] When the rotating shaft 22 rotates, it pushes the protruding part 32 to drive the connecting shaft 31 to rotate coaxially and in the same direction. When the protruding part 32 passes through the guiding part 39, the guiding part 39 guides the protruding part 32 so that the protruding part 32 drives the connecting shaft 31 to move upward and stretch the second elastic part 38. At the same time, the connecting shaft 31 drives the toothed plate 36 to move upward, and the toothed plate 36 drives the two connecting plates 33 and the two material leakage plates 34 to change from a horizontal state to a conical state. At this time, the first elastic part 37 is in a relaxed state. Under the positioning action of the first elastic part 37, the blocking plate 35 blocks the leakage holes on the material leakage plate 34, and then solid materials can be put into the material containing cavity. After the convex part 32 disengages from the guiding part 39, the elastic part two 38 drives the connecting shaft 31, the convex part 32 and the toothed plate 36 to move downward and reset. The toothed plate 36 drives the two connecting plates 33 and the two material leakage plates 34 to change from the conical state to the horizontal state. During this process, the connecting plate 33 squeezes the blocking plate 35, so that the blocking plate 35 slides on the material leakage plate 34 and squeezes the elastic part one 37, thereby gradually opening the material leakage holes on the material leakage plate 34. At this time, the solid material can pass through the material leakage holes on the material leakage plate 34 and fall into the liquid material in the reaction chamber.

[0051] As Figure 2 , Figure 6 , Figure 7 and Figure 8 shown, the opening and closing mechanism 4 includes four opening and closing parts, and the four opening and closing parts are respectively connected to four groups of stirring parts 23. The opening and closing part includes a moving frame 41, a connecting arm 42, an opening and closing part 43, a fixing part 44, an elastic part three 45 and a round rod 46. The moving frames 41 on the four opening and closing parts are respectively rotatably connected to the two connecting plates 33 and the two blocking plates 35. One end of the connecting arm 42 is rotatably connected to the bottom of the moving frame 41, and the other end of the connecting arm 42 is rotatably connected to the rotating shaft 22. The fixing parts 44 on the four opening and closing parts are respectively connected to four groups of stirring parts 23, and the stirring part 23 penetrates through the moving frame 41. The number of the opening and closing parts 43 and the elastic part three 45 are both set to two. The two opening and closing parts 43 are connected to the moving frame 41 through the two elastic parts three 45. The two opening and closing parts 43 are both slidably connected to the fixing part 44. Two inclined surfaces 441 are provided on the fixing part 44. The two opening and closing parts 43 are respectively in contact with the two inclined surfaces 441. The opening and closing part 43 can move away from each other under the guidance of the two inclined surfaces 441 and can drive the two opening and closing parts 43 to approach each other under the action of the elastic part three 45, so as to realize the opening and closing operation of the four opening and closing parts. When the four opening and closing parts open and close, they can disturb the liquid material close to the enamel coating and form a buffer area.

[0052] The top of the moving frame 41 is rotatably connected to the bottom of the blocking plate 35 through a round rod 46. The round rod 46 is fixed to the bottom of the blocking plate 35, and the moving frame 41 is rotatably connected to the round rod 46. The round rod 46 can move along its own axis, so that when the blocking plate 35 moves, it drives the round rod 46 to move. At this time, the moving frame 41 still maintains a rotatably connected state with the round rod 46.

[0053] The stirring part 23 includes a sleeve rod, a plug rod and a spring. The sleeve rod is connected to the rotating shaft 22. The plug rod is inserted into one end of the sleeve rod away from the rotating shaft 22. The spring is installed inside the sleeve rod and contacts the plug rod. One end of the plug rod extending out of the sleeve rod is threadedly connected to the fixing part 44. When disassembling the fixing part 44 from the stirring part 23, turn the plug rod to make the plug rod disengage from the fixing part 44, so as to facilitate the installation and disassembly between the opening and closing mechanism 4 and the stirring part 23. The elastic force of the spring is greater than the elastic force of the third elastic part 45, so as to facilitate the two opening and closing parts 43 to move away from each other under the guidance of the inclined surface 441.

[0054] When the two connecting plates 33 and the two material leakage plates 34 are in a horizontal state, the two opening and closing parts 43 in the same group are in contact with each other and both are in contact with the enamel coating. At this time, when the rotating shaft 22 drives the stirring part 23 to rotate, the stirring part 23 can drive the opening and closing mechanism 4 to move along a circular track and scrape the inner wall attached to the enamel coating; When the two connecting plates 33 and the two material leakage plates 34 change from the horizontal state to the conical state, the two connecting plates 33 and the two material leakage plates 34 drive the four moving frames 41 on the four opening and closing parts to tilt and move towards the direction close to the rotating shaft 22, and pull the four connecting arms 42 to rotate. At this time, because the elastic force of the spring in the stirring part 23 is greater than the elastic force of the third elastic part 45, the two opening and closing parts 43 move away from each other under the guiding action of the inclined surface 441, so as to open the two opening and closing parts 43. When the two connecting plates 33 and the two material leakage plates 34 are converted into the horizontal state, the four opening and closing parts are reset, so that the two opening and closing parts 43 on the same opening and closing part approach and close and reset each other. Through the continuous opening and closing of the two opening and closing parts 43 on the opening and closing part, the liquid material close to the enamel coating is turbulently flowed and a buffer area is formed, avoiding a large impact on the enamel coating by the solid material.

[0055] Working principle: The liquid material is conveyed into the reaction cavity in the reaction kettle 1. When the rotating shaft 22 rotates, it pushes the convex part 32 to drive the connecting shaft 31 to rotate coaxially and in the same direction. When the convex part 32 passes through the guiding part 39, the guiding part 39 guides the convex part 32, so that the convex part 32 drives the connecting shaft 31 to move upward and stretch the second elastic part 38. At the same time, the connecting shaft 31 drives the toothed plate 36 to move upward, and the toothed plate 36 drives the two connecting plates 33 and the two material leakage plates 34 to change from the horizontal state to the conical state. At this time, the first elastic part 37 is in a relaxed state. Under the positioning action of the first elastic part 37, the plugging plate 35 plugs the material leakage holes on the material leakage plate 34 to form a material holding cavity, and then the solid material can be put into the material holding cavity.

[0056] After the convex part 32 disengages from the guiding part 39, the elastic part two 38 drives the connecting shaft 31, the convex part 32 and the toothed plate 36 to move downward and reset. The toothed plate 36 drives the two connecting plates 33 and the two material leakage plates 34 to change from the conical state to the horizontal state. During this process, the connecting plate 33 squeezes the blocking plate 35, so that the blocking plate 35 slides on the material leakage plate 34 and squeezes the elastic part one 37, thereby gradually opening the material leakage holes on the material leakage plate 34. At this time, the solid material can pass through the material leakage holes on the material leakage plate 34 and fall into the liquid material in the reaction chamber.

[0057] When the two connecting plates 33 and the two material leakage plates 34 are in the horizontal state, the two opening and closing parts 43 in the same group are in contact with each other and both are in contact with the enamel coating. At this time, when the rotating shaft 22 drives the stirring part 23 to rotate, the stirring part 23 can drive the opening and closing mechanism 4 to move along a circular track and scrape the inner wall attached to the enamel coating.

[0058] When the two connecting plates 33 and the two material leakage plates 34 change from the horizontal state to the conical state, the four moving frames 41 on the four opening and closing parts are driven by the two connecting plates 33 and the two material leakage plates 34 to tilt and move towards the direction close to the rotating shaft 22, and the four connecting arms 42 are pulled to rotate. At this time, because the elastic force of the spring in the stirring part 23 is greater than the elastic force of the elastic part three 45, the two opening and closing parts 43 move away from each other under the guiding action of the inclined surface 441, thereby opening the two opening and closing parts 43. When the two connecting plates 33 and the two material leakage plates 34 are converted into the horizontal state, the four opening and closing parts are reset, so that the two opening and closing parts 43 on the same opening and closing part approach and close and reset each other. Through the continuous opening and closing of the two opening and closing parts 43 on the opening and closing part, the liquid material close to the enamel coating is turbulently flowed and a buffer area is formed.

Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
