Description

Technical Field

[0001] The invention relates to the technical field of enamel reactors, in particular to a chemical enamel internally heated reactor. Background Art

[0002] The enamel reactor is an excellent corrosion-resistant equipment. It is made by lining the inner surface of a steel container with a glass lining containing high silicon dioxide, and then firmly adhering to the metal surface through high-temperature burning to form a composite material product. Therefore, it has the dual advantages of the stability of glass and the strength of metal.

[0003] When the materials in the enameled reactor are reacted and synthesized, it is necessary to rotate the stirring shaft installed on the tank body through the mechanical sealing assembly to stir the materials so that the materials react fully and evenly. Since the stirring shaft is long and the rigidity is reduced, the stirring shaft will be subject to greater resistance during stirring and bend and deform. At this time, the stirring shaft will vibrate during rotation, and the stirring shaft will collide with the inner wall of the enameled reactor, causing damage to the enamel layer. A solution is provided in the prior art. For example, patent application No. CN202223471573.1 provides a shock-absorbing structure for an enameled reactor for textile additives. The patent provides a shock-absorbing structure for an enameled reactor for textile additives, including a tank body, a support, a driving motor, a stirring shaft and stirring blades. A jacket is provided outside the tank body, and a supporting portion is provided around the outer wall of the jacket. A support portion is provided between the supporting portion and the support. There is an elastic buffer structure, and at least two straightening structures are provided on the inner wall of the tank body along the height direction. The straightening structure includes several fixing frames and correction sleeves. A correction groove with interference fit with the stirring shaft is provided in the middle of the correction sleeve along the vertical direction. The correction groove is coaxial with the output shaft of the driving motor. A first buffer layer is provided on the outer wall of the stirring shaft and located at the same position as the correction groove. There is a gap between the first buffer layer and the correction groove. The utility model can transmit and slow down the vibration generated in the tank body to avoid damage to the tank body, while absorbing the vibration generated by the deflection of the stirring shaft, fully reducing the overall vibration, and improving the working stability of the enamel reactor. However, the stirring shaft will still rub against the connection with the tank body during the stirring process, which increases the gap between the stirring shaft and the tank body, increases the vibration amplitude of the stirring shaft, collides with the side wall of the tank body, and causes damage to the enamel layer on the inner wall of the tank body and the surface of the stirring shaft. Summary of the invention

[0004] The purpose of the present invention is to provide a chemical enamel internal heating reactor to solve the problem that the stirring shaft will still rub against the connection with the tank body during the stirring process, which will increase the gap between the stirring shaft and the tank body, increase the vibration amplitude of the stirring shaft, and collide with the side wall of the tank body, causing damage to the enamel layer on the inner wall of the tank body and the surface of the stirring shaft.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A chemical enamel internal heating reactor, comprising a tank body, a moving ring, a static ring and a clamping block, the tank body is vertically installed on a tripod, a motor is coaxially installed on the tank body, a stirring shaft is coaxially rotatably installed on the tank body, the motor is connected to the stirring shaft, a moving ring and a compression spring are coaxially installed on the stirring shaft, a static ring is coaxially installed on the tank body, two ends of the compression spring are respectively connected to the moving ring and the tank body, the end face of the static ring is slidably connected to the end face of the moving ring, more than three clamping blocks are annularly slidably installed in the tank body, the clamping blocks are arc-shaped, and a plurality of the clamping blocks are coaxially arranged with the moving ring, a driving assembly and a triggering assembly are provided in the tank body, the driving assembly is connected to the clamping blocks, the triggering assembly is respectively connected to the moving ring and the driving assembly, the triggering assembly is used to trigger the driving assembly when the stirring shaft is deflected, and the driving assembly is used to drive the clamping blocks to clamp the stirring shaft when the stirring shaft is deflected.

[0007] When the stirring shaft is stirring, friction occurs at the connection with the tank body, causing the gap between the stirring shaft and the tank body to increase and cause a large swing. The trigger component senses the deflection of the stirring shaft, and then triggers the drive component to drive the clamp to clamp the moving ring, thereby applying radial force to the moving ring, thereby preventing the stirring shaft coaxially connected to it from deflecting, avoiding the stirring shaft from colliding with the side wall of the tank body, causing damage to the enamel layer on the inner wall of the tank body and the surface of the stirring shaft, thereby protecting the integrity of the enamel layer on the inner wall of the tank body and extending the service life of the tank body.

[0008] Preferably, the trigger assembly includes a No. 1 wire ring, a No. 2 wire ring, a coil, a magnetic rod and a conductive ring, the conductive ring is installed on the outer diameter of the stirring shaft, the No. 1 wire ring and the No. 2 wire ring are installed in the tank body and are coaxially arranged with the stirring shaft, the No. 1 wire ring is gap-matched with the No. 2 wire ring and the conductive ring, the horizontal projections of the inner walls of the No. 1 wire ring and the No. 2 wire ring coincide, the magnetic rod is slidably installed in the moving ring and coaxially arranged in the coil, the axial direction of the magnetic rod is perpendicular to the axial direction of the moving ring, and is connected to the driving block, the No. 1 wire ring and the No. 2 wire ring are electrically connected to the positive and negative poles of the coil respectively, the vertical projections of the No. 1 wire ring and the No. 2 wire ring are located within the vertical projection of the conductive ring, and when the conductive ring is connected to the No. 1 wire ring and the No. 2 wire ring, the coil is energized to drive the magnetic rod to release the position restriction on the driving assembly.

[0009] When the positive and negative poles of the coil are connected, a magnetic field is formed in the coil, which drives the magnetic rod to move, thereby releasing the restriction on the drive component. The positive and negative poles of the coil are connected to the No. 1 wire ring and the No. 2 wire ring. When the stirring deflects, the moving ring and the conductive ring are deflected, and the offset conductive ring contacts the No. 1 wire ring and the No. 2 wire ring, so that the coil forms a loop. At the same time, the horizontal projections of the inner walls of the No. 1 wire ring and the No. 2 wire ring coincide. When the moving ring deflects, etc., the conductive ring can accurately contact the No. 1 wire ring and the No. 2 wire ring at the same time, thereby accurately controlling the on and off of the trigger coil loop, realizing precise control of the drive component, and improving the triggering accuracy and reliability of the entire system.

[0010] Preferably, the driving assembly includes a driving block and a driving spring, and the sliding direction of the multiple clamping blocks points to the axis of the dynamic ring. The driving block is vertically slidably installed in the tank body, and the side wall of the driving block is provided with a limiting groove. The magnetic rod and the limiting groove cooperate with each other. The driving block is connected to the tank body through the driving spring, and the inner wall of the driving block and the outer wall of the clamping block are provided with inclined surfaces, and the inclined surfaces are slidably connected, and the horizontal length of the inclined surface is greater than the distance between the inner wall of the clamping block and the outer wall of the dynamic ring.

[0011] By cooperating with the limit groove and the magnetic rod, the magnetic rod can limit the longitudinal position of the driving block. When the restriction on the driving block is released, the driving spring is released and the driving block moves to the east. At this time, the inclined surface set on the inner wall of the driving block and the outer wall of the clamping block can convert the longitudinal movement of the driving block into the horizontal movement of the clamping block, thereby driving the clamping block to clamp the moving ring, and the driving block plays a supporting role on the clamping block. At the same time, the horizontal length of the inclined surface is greater than the distance between the inner wall of the clamping block and the outer wall of the moving ring, which can ensure that the clamping block has enough moving distance in the horizontal direction, thereby reliably clamping the moving ring and ensuring that the moving ring will not be driven during the working process, thereby avoiding the swing of the stirring shaft coaxially connected with it, and colliding with the inner wall of the tank body, damaging the enamel layer, and ensuring the normal operation of related equipment.

[0012] Preferably, a plurality of convex teeth are evenly distributed on the upper end surface of the clamping block, the cross-section of the convex teeth is triangular, the convex teeth on the same clamping block are arranged in parallel, and the opening direction of the convex teeth is the same as the sliding direction of the clamping block.

[0013] The convex teeth arranged parallel to the upper end face of the clamp block make the contact between the clamp block and the tank body change from the original possible plane contact to local contact at the apex of the convex teeth, thereby reducing the contact area between the upper end face of the clamp block and the tank body. The reduction in contact area directly reduces the friction between the clamp block and the tank body. During the sliding process of the clamp block, smaller friction means that the clamp block encounters less resistance and slides more smoothly. It can respond more flexibly to the action of the drive block, realize rapid clamping of the dynamic ring, and improve the response speed of the entire device. At the same time, reducing the contact area can reduce the degree of wear between the clamp block and the tank body, which helps to extend the service life of the clamp block and the tank body and reduce equipment failures and maintenance costs caused by wear.

[0014] Preferably, buckles are provided on both sides of the driving block, the buckles are parallel to the axis of the dynamic ring, and the buckles are located in the horizontal projection plane of the inclined surface. When the clamping block is connected to the dynamic ring, the buckles cooperate with the upper end surface of the clamping block.

[0015] When the clamp block is connected to the moving ring, the deflection force of the moving ring acts on the clamp block. Since the clamp block is slidably installed in the tank body, and the inner wall of the drive block and the outer wall of the clamp block are provided with inclined surfaces, the clamp block will retract at this time, the moving ring and the agitator shaft will lose support, and the agitator shaft will collide with the side wall of the tank body, causing damage to the enamel layer on the inner wall of the tank body and the surface of the agitator shaft. Through the design of the buckle, the position between the clamp block and the supporting surface is locked to prevent the clamp block from being displaced when it is affected by the deflection force of the moving ring, and then separated from the moving ring, losing the radial clamping force on the moving ring, causing the agitator shaft to collide with the side wall of the tank body, thereby protecting the integrity of the enamel layer on the inner wall of the tank body and extending the service life of the tank body.

[0016] Preferably, multiple rollers are rotatably mounted on the inner wall of the clamping block, the rollers are symmetrically arranged, and the rollers are parallel to the axis of the moving ring.

[0017] The roller is parallel to the axis of the moving ring and is rotatably installed on the inner wall of the clamp. This design converts the sliding friction of the direct contact between the moving ring and the clamp into the rolling of the roller, avoiding the clamp from directly locking the rotating moving ring, ensuring that the stirring shaft can continuously and stably stir the material according to the preset process requirements, eliminating the problem of insufficient material mixing due to equipment failure and uneven stirring, avoiding the discard of a whole batch of materials due to unqualified quality, and reducing waste from the source.

[0018] Furthermore, the setting of more than three pairs of rollers greatly improves the reliability of the equipment. On the one hand, multiple rollers disperse the bearing pressure and reduce the risk of failure of a single roller. The pressure and torque borne by a single roller are greatly reduced. According to the principles of material mechanics, smaller rollers can be selected while meeting the same strength requirements. Small-sized rollers not only consume less material, but also significantly reduce the cost of raw material procurement. In addition, the processing difficulty and working hours are simultaneously reduced, and the manufacturing cost can be effectively controlled. On the other hand, even if individual rollers are worn or damaged, the remaining rollers can still maintain the basic operation of the dynamic ring to ensure uninterrupted mixing, making the production process continuous and stable, and reducing material losses and production stagnation waste caused by sudden equipment problems.

[0019] Preferably, a support ring is provided in the tank body, the support ring is coaxially installed with the moving ring, the line ring No. 1 and the line ring No. 2 are installed on the support ring, the inner walls of the line ring No. 1 and the line ring No. 2 coincide with the horizontal projection of the inner walls of the support ring, the vertical projections of the line ring No. 1 and the line ring No. 2 are located inside the support ring, and the support ring is made of elastic insulating material.

[0020] The Line 1 Ring and the Line 2 Ring are installed centrally on the support ring to avoid offset of the Line 1 Ring and the Line 2 Ring when they are installed in the tank, which affects the overlap of the horizontal projections of the inner walls of the Line 1 Ring and the Line 2 Ring, and affects the triggering accuracy and reliability of the entire system. At the same time, this integrated installation method also facilitates subsequent line connection, debugging and maintenance work. The staff can find the corresponding parts more quickly for operation, which improves the efficiency of maintenance of the entire equipment.

[0021] Furthermore, during the stirring process, when the moving ring is deflected, the No. 1 and No. 2 line rings in direct contact with it are easily deformed due to squeezing under the deflection force of the moving ring, and the support ring is made of elastic material, which can rely on its own elastic buffering and absorption of the pressure transmitted by the deflection force of the moving ring, thereby playing a good protective role. At the same time, the support ring will undergo a certain degree of elastic deformation to disperse and offset these forces, thereby avoiding squeezing and deformation of the No. 1 and No. 2 line rings due to excessive local force, thereby ensuring the structural integrity and normal function.

[0022] Preferably, the inclined surface includes a first inclined surface and a second inclined surface, the inclined surface on the clamping block is the first inclined surface, and the inclined surface on the driving block is the second inclined surface. The plane roughness of the first inclined surface Ra=0.1, and is smaller than the plane roughness of the second inclined surface, and the horizontal projection length of the second inclined surface is greater than the vertical projection length of the first inclined surface.

[0023] During the use of the clamp block and the drive block, the inclined surface of the connection will be worn, which will change the size of the clamp block and the drive block, resulting in a reduction in the locking force of the clamp block on the dynamic ring and a decrease in the response speed of the entire device. Therefore, it needs to be replaced in time. Relatively speaking, since multiple rollers are installed on the block, it is not convenient to replace, while the drive block is easier to replace and maintain. Therefore, the surface roughness of the first inclined surface Ra=0.1 is set greater than the surface roughness of the second inclined surface. This makes the friction force mainly concentrated on the second inclined surface of the drive block during relative sliding. When the worn parts need to be replaced, only the drive block needs to be replaced, reducing the difficulty and cost of maintenance.

[0024] Furthermore, setting the horizontal projection length of the second bevel to be greater than the vertical projection length of the first bevel can compensate for the distance change caused by wear to a certain extent, so that the clamp can still effectively clamp the moving ring, maintain the normal working performance of the equipment, and reduce the need for frequent adjustment or replacement of parts due to wear.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention can sense the deflection of the stirring shaft in real time by providing a trigger component, a drive component and a clamping block and other structures matched therewith, and quickly drive the clamping block to clamp the moving ring, thereby preventing the stirring shaft from further deflecting, effectively avoiding the collision of the stirring shaft with the tank body during the stirring process, damaging the enamel layer on the inner wall of the tank body and the surface of the stirring shaft, ensuring the integrity of the enamel layer, and extending the service life of the equipment.

[0027] 2. In the present invention, through the design of the No. 1 wire ring, the No. 2 wire ring, the conductive ring and other components, and utilizing their specific positional relationship and mutual coordination, the conductive ring can accurately and simultaneously contact the No. 1 wire ring and the No. 2 wire ring when the stirring shaft is deflected, thereby accurately controlling the on and off of the trigger coil circuit, achieving accurate triggering of the drive component, and improving the response efficiency from detecting anomalies to taking protective measures. At the same time, the support ring is made of elastic insulating material, which can buffer the extrusion of the No. 1 wire ring and the No. 2 wire ring by the deflection force of the dynamic ring, prevent their deformation, and ensure the normal function of the electrical components. On the other hand, the insulation characteristics ensure electrical safety and reduce electromagnetic interference.

[0028] 3. The present invention ensures reliable transmission and stable maintenance of the clamping force of the clamping block on the dynamic ring through the coordination and arrangement of the clamping block and the arrangement of the buckle on the driving block. At the same time, the roughness, length and other parameters of the inclined surface on the clamping block are optimized, so that after long-term use and wear, the relatively easy-to-operate driving block can be replaced more conveniently to reduce maintenance costs. At the same time, the convex teeth, roller shaft and other designs on the clamping block play a role in reducing friction, preventing locking, etc., thereby improving the working performance of the clamping block itself and the smoothness of its cooperation with other components.

[0038] See also Figures 1 to 8 The present invention provides a chemical enamel internal heating reactor, and the technical solution is as follows:

[0039] A chemical enamel internal heating reactor comprises a tank body 12, a moving ring 15, a stationary ring 16 and a clamping block 2. The tank body 12 is vertically mounted on a tripod 1. A motor 13 is coaxially mounted on the tank body 12. A stirring shaft 14 is coaxially mounted on the tank body 12. The motor 13 is connected to the stirring shaft 14. A moving ring 15 and a compression spring 17 are coaxially mounted on the stirring shaft 14. A stationary ring 16 is coaxially mounted on the tank body 12. Both ends of the compression spring 17 are respectively connected to the moving ring 15 and the tank body 12. The end face of the stationary ring 16 is slidably connected to the end face of the moving ring 15. The entire reactor is centered on the tank body 12. The tank body 12 is vertically mounted on a stable tripod 1 to provide a closed and safe space for the internal chemical reaction. The motor 13 coaxially mounted above the tank body 12 serves as a power source and is connected to the stirring shaft 14. When the motor 13 is powered on and started, the motor 13 drives the stirring shaft 14 to rotate, and the material in the tank body 12 is stirred through the stirring shaft 14. At the same time, a moving ring 15 and a compression spring 17 are coaxially mounted on the stirring shaft 14, and a stationary ring 16 is coaxially mounted on the tank body 12. The two ends of the compression spring 17 are respectively connected to the moving ring 15 and the tank body 12, and the end face of the stationary ring 16 is slidably connected to the end face of the moving ring 15. Through the contact between the end faces of the moving ring 15 and the stationary ring 16 and the action of the compression spring 17, the tank body 12 is tightly connected to the stirring working state, thereby ensuring the sealing inside the tank body 12;Three upper clamping blocks 2 are annularly slidably installed in the tank body 12. The clamping blocks 2 are arc-shaped. Multiple clamping blocks 2 are coaxially arranged with the moving ring 15. A driving component 3 and a triggering component 4 are arranged in the tank body 12. The driving component 3 is connected to the clamping blocks 2. The triggering component 4 is respectively connected to the moving ring 15 and the driving component 3. The triggering component 4 is used to trigger the driving component 3 when the stirring shaft 14 deflects. The driving component 3 is used to drive the clamping blocks 2 to clamp the stirring shaft 14 when the stirring shaft 14 deflects. The triggering component 4 includes a first wire ring 41, a second wire ring 42, The coil 43, the magnetic rod 44 and the conductive ring 45, the conductive ring 45 is installed on the outer diameter of the stirring shaft 14, the first wire ring 41 and the second wire ring 42 are installed in the tank body 12, and are coaxially arranged with the stirring shaft 14, the first wire ring 41 and the second wire ring 42 and the conductive ring 45 are gap-matched, and the horizontal projections of the inner walls of the first wire ring 41 and the second wire ring 42 coincide, the magnetic rod 44 is slidably installed in the moving ring 15, and is coaxially arranged in the coil 43, the axial direction of the magnetic rod 44 is perpendicular to the axial direction of the moving ring 15, and is connected to the driving block 31, a The first and second wire rings 41 and 42 are electrically connected to the positive and negative poles of the coil 43 respectively. The vertical projections of the first and second wire rings 41 and 42 are located within the vertical projection of the conductive ring 45. When the gap between the stirring shaft 14 and the tank body 12 increases due to friction between the two, the swing amplitude of the stirring shaft 14 increases, thereby driving the ring 15 to swing. At this time, the conductive ring 45 on the moving ring 15 is connected to the first and second wire rings 41 and 42, and the coil 43 is energized to drive the magnetic rod 44 to release the position restriction on the driving component 3, and the driving component 3 comprises a driving block 31 and a driving spring 32, the sliding direction of the plurality of clamping blocks 2 points to the axis of the moving ring 15, the driving block 31 is vertically slidably installed in the tank body 12, the side wall of the driving block 31 is provided with a limiting groove 311, the magnetic rod 44 cooperates with the limiting groove 311, the driving block 31 is connected to the tank body 12 through the driving spring 32, the inner wall of the driving block 31 and the outer wall of the clamping block 2 are provided with an inclined surface 34, and the inclined surfaces 34 are slidably connected, and the horizontal length of the inclined surface 34 is greater than the distance between the inner wall of the clamping block 2 and the outer wall of the moving ring 15;When the stirring shaft 14 is stirring, it will still rub against the connection between the tank body 12, which will increase the gap between the stirring shaft 14 and the tank body 12, and then cause the stirring shaft 14 to deflect during the stirring process. When the moving ring 15 is deflected, the conductive ring 45 can accurately contact the No. 1 wire ring 41 and the No. 2 wire ring 42 at the same time. At this time, the coil 43 forms a loop, and a magnetic field is formed in the coil 43, which drives the magnetic rod 44 to move. The magnetic rod 44 is separated from the limit groove 311 on the driving block 31. At this time, the magnetic rod 44 releases the longitudinal position restriction on the driving block 31. The dynamic spring 32 pushes the driving block 31 to move in the longitudinal direction. The inclined surface 34 provided on the inner wall of the driving block 31 and the outer wall of the clamping block 2 converts the longitudinal movement of the driving block 31 into the horizontal movement of the clamping block 2. At this time, the clamping block 2 clamps the dynamic ring and applies radial force to the dynamic ring, thereby preventing the agitator shaft 14 coaxially connected thereto from deflecting, thus preventing the agitator shaft 14 from colliding with the side wall of the tank body 12, causing damage to the enamel layer on the inner wall of the tank body 12 and the surface of the agitator shaft 14, protecting the integrity of the enamel layer on the inner wall of the tank 12 and extending the service life of the tank body 12. ;

[0040] See also Figure 5 , Figure 7 and Figure 8 The upper end surface of the clamp block 2 is evenly distributed with a plurality of convex teeth 21, and the cross-section of the convex teeth 21 is triangular. The convex teeth 21 on the same clamp block 2 are arranged in parallel, and the opening direction of the convex teeth 21 is the same as the sliding direction of the clamp block 2. Through the convex teeth 21 arranged in parallel on the upper end surface of the clamp block 2, the contact between the clamp block 2 and the tank body 12 is changed from the original possible plane contact to a local contact at the vertex of the convex teeth 21, thereby reducing the contact area between the upper end surface of the clamp block 2 and the tank body 12. The reduction in the contact area directly reduces the friction between the clamp block 2 and the tank body 12, making the sliding of the clamp block 2 smoother, thereby realizing the rapid clamping of the dynamic ring 15 and improving the response speed of the entire device; multiple roller shafts 22 are rotatably installed on the inner side wall of the clamp block 2, and the roller shafts 22 are symmetrically arranged. The roller shafts 22 are parallel to the axis of the dynamic ring 15. This design converts the sliding friction between the dynamic ring 15 and the clamp block 2 in direct contact into The rolling of the roller 22 prevents the clamping block 2 from directly locking the rotating ring 15, ensuring that the stirring shaft 14 can continuously and stably stir the material according to the preset process requirements, avoiding the discard of a whole batch of materials due to unqualified quality, and reducing waste from the source; the inclined surface 34 includes a first inclined surface 341 and a second inclined surface 342, the inclined surface 34 on the clamping block 2 is the first inclined surface 341, and the inclined surface 34 on the driving block 31 is the second inclined surface 342, the plane roughness Ra of the first inclined surface 341 is 0.1, and is smaller than the plane roughness of the second inclined surface 342, the horizontal projection length of the second inclined surface 342 is greater than the vertical projection length of the first inclined surface 341, and during the relative sliding process, the friction force is mainly concentrated on the second inclined surface 342 of the driving block 31, so that when the worn parts need to be replaced, only the driving block 31 needs to be replaced, reducing the difficulty and cost of maintenance.

[0041] See also Figure 5 and Figure 6 , buckles 33 are provided on both sides of the driving block 31, and the buckles 33 are parallel to the axis of the dynamic ring 15. The buckles 33 are located in the horizontal projection plane of the inclined surface 34. When the clamping block 2 is connected to the dynamic ring 15, the buckles 33 cooperate with the upper end surface of the clamping block 2. Through the design of the buckles 33, the position between the clamping block 2 and the supporting surface is locked to prevent the clamping block 2 from being displaced when it is subjected to the deflection force of the dynamic ring 15, and then separated from the dynamic ring 15, losing the radial clamping force on the dynamic ring 15, causing the problem of collision between the stirring shaft 14 and the side wall of the tank body 12, thereby protecting the integrity of the enamel layer on the inner wall of the tank body 12 and extending the service life of the tank body 12.

[0042] See also Figure 2 and Figure 3 A support ring 46 is provided in the tank body 12, and the support ring 46 is coaxially installed with the dynamic ring 15. The No. 1 line ring 41 and the No. 2 line ring 42 are installed on the support ring 46. The inner walls of the No. 1 line ring 41 and the No. 2 line ring 42 coincide with the horizontal projection of the inner wall of the support ring 46. The vertical projections of the No. 1 line ring 41 and the No. 2 line ring 42 are located in the support ring 46. The support ring 46 is made of elastic insulating material. The No. 1 line ring 41 and the No. 2 line ring 42 are easily deformed due to extrusion under the deflection force of the dynamic ring 15, and the support ring 46 is made of rubber material, which has good elasticity and insulation, and can rely on its own elasticity to buffer and absorb the pressure transmitted by the deflection force of the dynamic ring 15, thereby playing a good protective role.

[0043] The trigger assembly 4 includes a No. 1 wire ring 41, a No. 2 wire ring 42, a coil 43, a magnetic rod 44 and a conductive ring 45. The conductive ring 45 is installed on the outer diameter of the stirring shaft 14. The No. 1 wire ring 41 and the No. 2 wire ring 42 are installed in the tank body 12 and are coaxially arranged with the stirring shaft 14. The No. 1 wire ring 41 is gap-matched with the No. 2 wire ring 42 and the conductive ring 45. The No. 1 wire ring 41 is gap-matched with the No. 2 wire ring 42 and the conductive ring 45. The horizontal projections of the inner walls of the No. 1 wire ring 41 and the No. 2 wire ring 42 coincide. The magnetic rod 44 is slidably installed in the moving ring 15 and is coaxially arranged in the coil 43. The axial direction of the magnetic rod 44 is perpendicular to the axial direction of the moving ring 15 and is connected to the driving block 31. The No. 1 wire ring 41 and the No. 2 wire ring 42 are gap-matched with the conductive ring 45. The ring 42 is electrically connected to the positive and negative poles of the coil 43 respectively. The vertical projections of the No. 1 wire ring 41 and the No. 2 wire ring 42 are located within the vertical projection of the conductive ring 45. When the conductive ring 45 is connected to the No. 1 wire ring 41 and the No. 2 wire ring 42, the coil 43 is energized to drive the magnetic rod 44 to release the position restriction on the driving component 3. A support ring 46 is provided in the tank body 12. The support ring 46 is coaxially installed with the moving ring 15. The No. 1 wire ring 41 and the No. 2 wire ring 42 are installed on the support ring 46. The inner side walls of the No. 1 wire ring 41 and the No. 2 wire ring 42 coincide with the horizontal projection of the inner side wall of the support ring 46. The vertical projections of the No. 1 wire ring 41 and the No. 2 wire ring 42 are located within the support ring 46. The support ring 46 is made of rubber material.

[0044] Working principle: When the stirring shaft 14 deflects during the stirring process, the driving ring 15 is driven to deflect, and the conductive ring 45 contacts the No. 1 wire ring 41 and the No. 2 wire ring 42 at the same time. At this time, the coil 43 forms a loop, and a magnetic field is formed in the coil 43, which drives the magnetic rod 44 to move. The magnetic rod 44 is separated from the limit groove 311 on the driving block 31. At this time, the magnetic rod 44 releases the longitudinal position restriction of the driving block 31. Under the action of the driving spring 32, the driving block 31 is pushed to move in the longitudinal direction. Through the inclined surface 34 set on the inner wall of the driving block 31 and the outer wall of the clamping block 2, the driving block 31 is driven to move in the longitudinal direction. The movement of the movable block 31 in the longitudinal direction is the movement of the clamping block 2 in the horizontal direction. At this time, the clamping block 2 clamps the movable ring and applies radial force to the movable ring, thereby preventing the agitator shaft 14 coaxially connected thereto from deflecting, thereby avoiding the collision between the agitator shaft 14 and the side wall of the tank body 12. Through the design of the buckle 33, the position between the clamping block 2 and the supporting surface is locked. At the same time, when the clamping block 2 is to clamp the movable ring 15, the roller 22 converts the sliding friction of the direct contact between the movable ring 15 and the clamping block 2 into the rolling of the roller 22, thereby avoiding the clamping block 2 from directly locking the rotating movable ring 15.

For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments without departing from the principles and ideas of the present invention should still fall within the scope of protection of the present invention.
