Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to an organic waste gas treatment device for a circulating spraying production line. Background Art

[0002] There are two main types of organic waste gas in the spray room, namely paint mist and VOC, which are both organic solvents. The treatment method for this type of waste gas is generally a spray tower, a water curtain cabinet and an air suction device, and then adding a special deodorant or activated carbon for spraying for treatment. Because most of the organic waste gas is volatile organic compounds, they have great differences in properties from the particulate matter in the spray, so generally there is no dissolution relationship, and in the absence of obvious airflow interference, the organic waste gas may have a certain degree of diffusion and mixing due to its own density and other factors, and may appear to diffuse partially upward, partially downward, and all around. Therefore, water is generally used to absorb the organic waste gas or an air suction device is used to collect the organic waste gas, and then it is treated in an environmentally friendly way to avoid polluting the environment and endangering the health of employees.

[0003] In order to improve the waste gas treatment effect, the reverse spray method is often used to achieve waste gas purification. The packing layer is set on the upper layer of the spray tower to maximize the contact between the alkali solution and the waste gas, thereby enhancing the waste gas purification effect. However, since the packing balls are in a static state after being placed in the spray tower, and the waste gas contains oily substances, the packing balls are very likely to stick to each other when they are static for a long time, which will reduce the contact surface between the packing balls and the alkali solution and the waste gas, and ultimately cause the waste gas purification effect to decrease.

[0004] Chinese patent announcement number CN118341244B discloses an environmental protection device for treating waste gas, including a spray tower body, a pump box, an air inlet pipe and a packing layer plate, a sieving assembly is arranged inside the packing layer plate, and the sieving assembly includes a push plate for pushing the packing balls, a sleeve is fixedly connected to the outside of the push plate, and a spray assembly is arranged below the outside of the sleeve.

[0005] When the alkali liquid diffusion disk is moved upward in a spiral outside the column, the alkali liquid diffusion disk drives the connection component and causes the push plate in the screening component to rotate inside the filling slot. The rotation of the push plate drives the convex plate and pushes the filler balls inside the filling slot. By pushing the filler balls inside the filling slot, the filler balls are kept in a state of motion and vibration during operation, thereby avoiding the adhesion of the filler balls caused by standing still. However, the scope of use of this environmental protection equipment is limited to situations where the amount of filler balls accumulated is small. When the number of filler balls accumulated is large, it is impossible to achieve the exchange of the upper and lower layer positions. Even if vibration is applied, it can only act on the filler balls in the lower layer, and the filler balls on the upper layer will still have adhesion problems. Summary of the invention

[0006] In view of the problems of the prior art, an organic waste gas treatment device for a circulating spraying production line is provided.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figure 1 , Figure 2 and Figure 3As shown, the present application provides an organic waste gas treatment device for a circulating spraying production line, including a treatment tower 1, a grid plate 2, a filler 3, a rotating shaft 4, a rotating drive 5, a stirring assembly 6 and a spray mechanism 7. The bottom of the treatment tower 1 is provided with an air inlet 11, and the top of the treatment tower 1 is provided with an air outlet 12; the grid plates 2 are arranged in the treatment tower 1 at equal intervals along the longitudinal direction, and a treatment chamber that can allow organic waste gas to pass through is formed between adjacent grid plates 2, all the treatment chambers are located between the air inlet 11 and the air outlet 12, and the treatment chamber is divided into a stacking chamber and a spraying chamber from bottom to top; the filler 3 is put into the stacking chamber ; The rotating shaft 4 is coaxially rotatably arranged in the processing tower 1, and the rotating shaft 4 passes through the grid plate 2 and slides with it; the rotary driver 5 is arranged at the bottom of the processing tower 1, and the output shaft of the rotary driver 5 is transmission-connected with the rotating shaft 4; the stirring assembly 6 is arranged in the processing chamber and is transmission-connected with the rotating shaft 4, and the stirring assembly 6 has a stirring roller group distributed along the circumference of the rotating shaft 4. When the rotating shaft 4 rotates, the stirring roller group revolves along the circumference of the rotating shaft 4 and rotates in the vertical direction to stir the filler 3; the spray mechanism 7 is arranged at the top of the spray chamber, and the spray mechanism 7 has a rectangular array of spray ports at the top of the stacking chamber.

[0034] The filler 3 includes but is not limited to filler balls filled with activated carbon or other adsorbents.

[0035] A drain port 13 is also provided at the bottom of the treatment tower 1 .

[0036] An air inlet 11 is carefully arranged at the bottom of the treatment tower 1 to introduce the organic waste gas to be treated. The air outlet 12 at the top is used to discharge the clean gas that meets the standards after treatment, and the drain port 13 at the bottom can promptly discharge the wastewater and other liquids generated during the treatment process to ensure the stability of the internal environment of the device and normal operation.

[0037] The grid plates 2 are arranged at equal intervals along the longitudinal direction of the treatment tower 1. The treatment chamber formed between adjacent grid plates 2 is a space for treating organic waste gas. All treatment chambers are located between the air inlet 11 and the air outlet 12. Each individual treatment chamber is divided into a stockpile chamber and a spray chamber from bottom to top. The fillers 3 are placed in the stockpile chamber in an orderly manner to provide basic conditions such as adsorption and reaction for subsequent waste gas treatment.

[0038] The rotating shaft 4 is precisely arranged in the treatment tower 1 in a coaxial rotation manner, and the rotating shaft 4 passes through the grid plate 2 and forms a smooth sliding fit with it. The rotary drive 5 located at the bottom of the treatment tower 1 includes a motor, which transmits power to the rotating shaft 4 through a transmission connection to drive it to rotate.

[0039] The stirring assembly 6 is installed in the processing chamber and is connected to the rotating shaft 4. When the rotating shaft 4 rotates, the circumferentially distributed stirring roller group will revolve along the circumference and rotate along the vertical direction at the same time, thereby achieving sufficient and efficient stirring of the filler 3 and improving the contact effect between the exhaust gas and the filler 3.

[0040] The spray mechanism 7 is arranged at the top of the spray chamber, and the spray ports thereof are distributed in a rectangular array at the top of the stockpile chamber, which can evenly spray the treatment liquid, further assisting the waste gas treatment.

[0041] like Figure 5 , Figure 7 and Figure 8 As shown, the stirring assembly 6 also includes a rotating cylinder 62, a stirring plate 63, a coaxial transmission and a vertical transmission. The rotating cylinder 62 is coaxially rotatably arranged in the material stacking chamber, and a rotating ring 621 coaxially rotatably connected to the rotating shaft 4 is arranged at the top of the rotating cylinder 62; the stirring plate 63 is circumferentially arranged on the outer side of the rotating cylinder 62, and the stirring plate 63 extends longitudinally. A driven shaft 631 that penetrates the rotating cylinder 62 and is rotatably connected to the rotating cylinder 62 is arranged at the center of the stirring plate 63, and the driven shaft 631 is fixedly connected to the stirring plate 63. The vertical transmission is arranged on the driven shaft 631 and the rotating shaft 4 to transmit torque. When the driving shaft 4 rotates, the driven shaft 631 drives the stirring plate 63 to rotate longitudinally; the stirring roller group includes two parallel stirring rollers 61, the stirring rollers 61 extend along the radial direction of the rotating cylinder 62, and the ends of the two stirring rollers are rotatably connected to the top and bottom ends of the stirring plate 63 respectively; the coaxial transmission is arranged between the inner wall of the rotating cylinder 62 and the circumferential surface of the rotating shaft 4 to transmit torque, and when the rotating shaft 4 rotates, the driven shaft 631 drives the rotating cylinder 62 to rotate coaxially; the vertical transmission is arranged at the top of the grid plate 2 and is connected to the driven shaft 631, and when the rotating cylinder 62 rotates, the driven shaft 631 rotates relative to the rotating cylinder 62.

[0042] The rotating cylinder 62 is coaxially rotatably arranged in the stacking cavity, and a rotating ring 621 is provided at the top thereof. The rotating ring 621 is coaxially rotatably connected with the rotating shaft 4 to ensure reliable transmission connection between the rotating cylinder 62 and the rotating shaft 4 .

[0043] The stirring plate 63 is arranged circumferentially on the outer side of the rotating cylinder 62 and extends longitudinally. A driven shaft 631 is provided at the center of the stirring plate 63, and the driven shaft 631 penetrates the rotating cylinder 62 and forms a rotational connection therewith. Vertical transmission devices are respectively provided on the driven shaft 631 and the rotating shaft 4, and their function is to transmit torque. When the rotating shaft 4 rotates, the driven shaft 631 can drive the stirring plate 63 to rotate longitudinally with the help of the vertical transmission device, thereby realizing a stirring action in a specific direction.

[0044] The stirring roller group includes two stirring rollers 61 arranged in parallel and extending radially along the rotating cylinder 62 , and two ends of the stirring rollers 61 are rotatably connected to the top and bottom ends of the stirring plate 63 respectively, so as to enhance the stirring range and effect of the filler 3 .

[0045] The coaxial transmission device is arranged between the inner wall of the rotating cylinder 62 and the circumferential surface of the rotating shaft 4, and is responsible for transmitting torque. When the rotating shaft 4 rotates, the driven shaft 631 can drive the rotating cylinder 62 to realize coaxial rotation. In addition, the vertical transmission device is also arranged at the top of the grid plate 2 and connected to the driven shaft 631, so as to ensure that when the rotating cylinder 62 rotates, the driven shaft 631 can rotate relative to the rotating cylinder 62, thereby ensuring the orderly operation of the entire stirring assembly 6.

[0046] like Figure 4 and Figure 8 As shown, the coaxial transmission includes a driving gear 641, a driven gear 642m and an inner gear ring 643. The driving gear 641 is coaxially fixedly arranged on the rotating shaft 4; the driven gear 642 is rotatably arranged on the top of the boss 21, and the driven gear 642 is meshed with the driving gear 641; the inner gear ring 643 is coaxially fixedly arranged on the inner wall of the rotating cylinder 62, and the inner gear ring 643 is meshed with the driven gear 642.

[0047] The driving gear 641 is fixedly arranged on the rotating shaft 4 so that it can rotate synchronously with the rotating shaft 4 and provide an initial power source for the subsequent transmission process.

[0048] There are at least two driven gears 642, which are distributed on the top of the boss 21 along the circumference of the rotating shaft 4. The driven gears 642 are set to be rotatable, installed on the top of the boss 21, and form a meshing relationship with the driving gear 641. When the driving gear 641 starts to rotate driven by the rotating shaft 4, the power can be transmitted to the driven gear 642 through the meshing action of the two, so that it rotates accordingly.

[0049] The inner gear ring 643 is coaxially fixedly arranged on the inner wall of the rotating cylinder 62, and is meshed again with the driven gear 642 that has obtained power and rotates. With the help of this meshing connection, the driven gear 642 can further transmit the received power to the inner gear ring 643, and then drive the rotating cylinder 62 connected thereto to achieve coaxial rotation, thereby ensuring that the entire coaxial transmission can stably and efficiently transmit torque between the rotating shaft 4 and the rotating cylinder 62, ensuring the normal operation of related equipment.

[0050] like Figure 4As shown, the inner circumferential surface of the rotating ring 621 is provided with a connecting cylinder 622 coaxial therewith, and the connecting cylinder 622 is rotatably connected with the circumferential surface of the rotating shaft 4, and the circumferential surface of the rotating shaft 4 is provided with a sealing ring 623 coaxial therewith, and the sealing ring 623 is located at the top of the connecting cylinder 622, and the outer circumferential surface of the sealing ring 623 is provided with a sealing cylinder 624 coaxial therewith, and the sealing cylinder 624 extends downward to the outside of the outer circumferential surface of the connecting cylinder 622, and an upper sealing ring is provided between the inner circumferential surface of the sealing cylinder 624 and the outer circumferential surface of the connecting cylinder 622.

[0051] A coaxial connecting tube 622 is disposed on the inner circumference of the rotating ring 621 . The connecting tube 622 and the circumference of the rotating shaft 4 form a rotating connection relationship, thereby ensuring that the two can achieve relative rotation and maintain corresponding connection stability.

[0052] A coaxial sealing ring 623 is provided on the circumferential surface of the rotating shaft 4, and the sealing ring 623 is located at the top of the connecting tube 622. A coaxial sealing tube 624 is further provided on the outer circumferential surface of the sealing ring 623, and the sealing tube 624 is in a downwardly extending shape, and after extending, it reaches the outer side of the outer circumferential surface of the connecting tube 622.

[0053] An upper sealing ring is provided between the inner circumference of the sealing cylinder 624 and the outer circumference of the connecting cylinder 622. The upper sealing ring can effectively fill the gap between the two, forming a reliable sealing structure, preventing foreign matter from entering the connecting part, and preventing fluid and other substances from entering the rotating cylinder 62 from the connecting part, thereby ensuring the sealing of the entire connecting structure during operation and the stable operation of the entire equipment.

[0054] like Figure 4 As shown, a boss 21 coaxial with the rotating shaft 4 is provided at the center position of the grille plate 2, the rotating shaft 4 passes through the boss 21 and slides with it, the bottom end of the rotating cylinder 62 extends to the outside of the outer circumferential surface of the boss 21, and a lower sealing ring is provided between the inner wall of the rotating cylinder 62 and the outer circumferential surface of the boss 21.

[0055] At the center of the grille plate 2, there is a boss 21 coaxial with the rotating shaft 4. The rotating shaft 4 is arranged to penetrate the boss 21 so that the rotating shaft 4 can rotate smoothly relative to the boss 21, ensuring the effective implementation of the rotation action and the reasonable operation of the overall structure.

[0056] The bottom end of the rotating cylinder 62 extends beyond the outer circumference of the boss 21, and a lower sealing ring is precisely arranged in the gap space formed by the inner wall of the rotating cylinder 62 and the outer circumference of the boss 21. The lower sealing ring can effectively fill the above gap and play a good sealing role, which can prevent internal and external media such as gas and liquid from entering the rotating cylinder 62 at this position, thereby ensuring the sealing of the entire device during operation and the stability of the coordinated work of various components.

[0057] like Figure 7 , Fig. 9 and Fig.10 As shown, the connecting end of the stirring roller m61 and the stirring plate 63 is provided with a stirring shaft 611 that penetrates the stirring plate 63 and is rotatably connected thereto, a fixed cylinder 625 coaxial with the driven shaft 631 is provided on the outer circumferential surface of the rotating cylinder 62, and a synchronous transmission is provided between the fixed cylinder 625 and the stirring shaft 611. When the driven shaft 631 rotates, the stirring shaft 611 rotates m relative to the stirring plate 63.

[0058] At the connection end between the stirring roller 61 and the stirring plate 63, a stirring shaft 611 is arranged. The stirring shaft 611 passes through the stirring plate 63 and forms a rotational connection relationship with the stirring plate 63, thereby ensuring that the stirring shaft 611 can flexibly rotate relative to the stirring plate 63 to meet the subsequent corresponding transmission and stirring requirements.

[0059] The outer circumferential surface of the rotating cylinder 62 is provided with a fixed cylinder 625 which is coaxial with the driven shaft 631, and a synchronous transmission is provided between the fixed cylinder 625 and the stirring shaft 611. When the driven shaft 631 starts to rotate, the power can be transmitted to the stirring shaft 611 by means of the transmission link constructed by the synchronous transmission, so that the stirring shaft 611 can drive the stirring roller 61 to perform a corresponding rotational action while rotating relative to the stirring plate 63, and then cooperate with other components to achieve effective stirring of the material, ensuring that the entire stirring assembly 6 operates stably and orderly, and achieving the expected filler 3 processing effect.

[0060] like Fig.10 As shown, the synchronous transmission includes a fixed sprocket 661, a rotating sprocket 662 and a synchronous chain 663. The fixed sprocket 661 is coaxially fixedly arranged on the outer circumferential surface of the fixed cylinder 625; the rotating sprocket 662 is coaxially fixedly arranged on the stirring shaft 611, and the diameter of the fixed sprocket 661 is larger than the diameter of the rotating sprocket 662; the synchronous chain 663 is sleeved on the fixed sprocket 661 and the rotating sprocket 662.

[0061] Because the fixed sprocket 661 is fixed on the outer circumference of the fixed cylinder 625, when the driven shaft 631 drives the stirring plate to rotate relative to the rotating cylinder 62, the rotating sprocket 662 installed on the stirring shaft 611 will revolve relative to the fixed sprocket 661, and the synchronous chain 663 is sleeved on the fixed sprocket 661 and the rotating sprocket 662. The synchronous chain 663 itself has a certain length and is in a tensioned state, and the contact surface of the synchronous chain 662 and the fixed sprocket 661 and the rotating sprocket 662 is in a meshing state. In the process of the rotating sprocket 662 revolving relative to the fixed sprocket 661, in order to maintain the meshing state with the synchronous chain 663 and maintain the tension of the synchronous chain 663, the rotating sprocket 662 will drive the stirring shaft 611 to rotate relative to the stirring plate 63.

[0062] During the revolution of the rotating sprocket 662, as its position changes continuously, the teeth at different parts of the synchronous chain 663 will continuously contact the gear teeth of the rotating sprocket 662. In order to coordinate with the sequential contact of the teeth of the synchronous chain 663, the rotating sprocket 662 needs to rotate itself to make its own gear teeth correctly engage and disengage with the teeth of the synchronous chain 663, thereby ensuring the normal operation of the entire transmission system.

[0063] like Fig.11 As shown, when the rotating sprocket 662 rotates 90 degrees relative to the fixed sprocket 661, the fixed sprocket 661 remains stationary. In order to maintain the meshing state of the synchronous chain 663 with the rotating sprocket 662 and the fixed sprocket 662, point A on the synchronous chain 663 is displaced to point A1, and point B is displaced to point B1. During this process, the positions of point A and point B on the synchronous chain 663 will be displaced in an alternating manner. The synchronous chain 663 will guide the rotating sprocket 662 to rotate relative to the fixed sprocket 661, so that the rotating sprocket 62 can drive the stirring shaft 611 to rotate relative to the stirring plate 63.

[0064] The stirring roller 61 can rotate relative to the stirring plate 63, which has the following advantages: Dispersed friction: During the stirring process, the filler 3 will generate friction on the stirring roller 61. If the stirring roller 61 cannot rotate relative to the stirring plate 63, then during the contact with the filler 3, certain parts of the surface of the stirring roller 61 will continue to be rubbed by the filler 3. When the stirring roller 61 can rotate relative to the stirring plate 63, the contact point between the surface of the stirring roller 61 and the filler 3 will continue to change, so that the friction distribution is more evenly dispersed on the entire surface of the stirring roller 61. Evenly dispersed friction can avoid excessive wear of the stirring roller 61 locally and extend the service life of the stirring roller 61.

[0065] Optimizing the force: When the stirring roller 61 can rotate relative to the stirring plate 63, the resistance of the filler 3 to the stirring roller 61 during the stirring process can be buffered and dispersed to a certain extent through its own rotation. In this way, the power required by the entire stirring system can be reduced to a certain extent. Because if the stirring roller 61 cannot rotate, it may be subject to a large resistance in a fixed direction, and rotation can decompose this resistance in different directions, reducing the demand for power and achieving energy saving.

[0066] like Fig.10 As shown, a protective cover 67 is also provided on the side of the stirring plate 63 facing the rotating cylinder 62 , and the fixed sprocket 661 , the rotating sprocket 662 and the synchronous chain 663 are all located in the protective cover 67 , and the driven shaft 631 passes through the protective cover 67 and is rotatably connected thereto.

[0067] A protective cover 67 is provided on the side of the stirring plate 63 facing the rotating cylinder 62. The protective cover 67 has a specific protective function, and is intended to provide effective protection for the relevant components inside the protective cover 67.

[0068] The three key components of the synchronous transmission, namely the fixed sprocket 661, the rotating sprocket 662 and the synchronous chain 663, are all covered in the internal space of the protective cover 67, so that they can avoid interference and damage from external factors such as dust, collision with foreign objects, etc., thereby ensuring the normal operation of the synchronous transmission and the performance stability of each component.

[0069] like Figure 6 As shown, the spray mechanism 7 includes a fixed seat 71 and a rotating seat 72. The fixed seat 71 is coaxially fixedly arranged at the top of the spray chamber. The rotating shaft 4 passes through the fixed seat 71 and is rotatably connected to the fixed seat 71. The fixed seat 71 has an annular water supply chamber coaxial with it. The fixed seat 71 is also provided with a water supply pipe 711 extending along its radial direction. The water supply pipe 711 passes through the treatment tower 1; the rotating seat 72 is coaxially rotatably arranged on the fixed seat 71 and is connected to the rotating shaft 4. The rotating seat 72 has an annular water separation chamber coaxial with it. The portion where the fixed seat 71 is connected to the rotating seat 72 is provided with a water supply port 712, and the portion where the rotating seat 72 is connected to the fixed seat 71 is provided with a water inlet 721. A spray pipe 73 extending along its radial direction is provided on the outer circumferential surface of the rotating seat 72. The spray pipe 73 is provided with nozzles 74 arranged along its length direction, and the spray pipe 73 is connected to the annular water separation chamber.

[0070] The fixed seat 71 is coaxially fixedly arranged at the top of the spray chamber, and the rotating shaft 4 passes through the fixed seat 71 and forms a rotational connection relationship with the fixed seat 71, so as to ensure that the rotating shaft 4 can rotate smoothly relative to the fixed seat 71, while ensuring the relevance and stability of the entire structure. The fixed seat 71 has an annular water supply cavity coaxial with it, and the water supply cavity is used to store and distribute the spray liquid. In addition, the fixed seat 71 is also provided with a water supply pipe 711 extending along its radial direction, and the water supply pipe 711 passes through the treatment tower 1, and its function is to introduce the external spray liquid into the annular water supply cavity, thereby constructing a complete water supply passage.

[0071] The rotating seat 72 is arranged on the fixed seat 71 in a coaxially rotating manner and is connected to the rotating shaft 4, so that the rotating seat 72 can rotate synchronously with the rotating shaft 4. The rotating seat 72 has an annular water diversion chamber coaxial with it, and a water supply port 712 is provided at the portion where the fixed seat 71 and the rotating seat 72 are connected. Correspondingly, a water inlet 721 is provided at the portion where the rotating seat 72 and the fixed seat 71 are connected. Through the docking of the water supply port 712 and the water inlet 721, water source transportation from the annular water supply chamber to the annular water diversion chamber can be realized. A spray pipe 73 extending in its radial direction is provided on the outer circumferential surface of the rotating seat 72, and nozzles 74 are arranged on the spray pipe 73 along its length direction, and the spray pipe 73 is connected to the annular water diversion chamber. When the spray liquid enters the annular water diversion chamber, it can be transported to the nozzle 74 through the spray pipe 73, and finally a uniform spraying operation is realized to meet the spraying treatment requirements of the relevant area.

[0072] like Figure 4 and Figure 7 As shown, the vertical transmission device includes a fixed ring platform 653, a fixed bevel gear 651 and a rotating bevel gear 652. The fixed ring platform 653 is coaxially arranged in the rotating cylinder 62 with the rotating shaft 4. The bottom end of the fixed ring platform 653 is provided with a connecting column 6531 extending downward and fixedly connected to the boss 21; the fixed bevel gear 651 is coaxially fixedly arranged on the fixed ring platform 653, and the inner diameters of the fixed bevel gear 651 and the fixed ring platform 653 are larger than the diameter of the rotating shaft 4; the rotating bevel gear 652 is coaxially fixedly arranged on the driven shaft 631, and the rotating bevel gear 652 is meshed with the fixed bevel gear 651.

[0073] There are at least two connecting posts 6531 , and the connecting posts 6531 are fixedly disposed on the top of the boss 21 along the circumferential direction of the rotating shaft 4 .

[0074] The fixed ring stage 653 is arranged inside the rotating cylinder 62 in a coaxial manner with the rotating shaft 4, and a connecting column 6531 extending downward is provided at its bottom end. A fixed connection is formed between the connecting column 6531 and the boss 21. Through this connection method, the fixed ring stage 653 can be firmly placed in the rotating cylinder 62, laying a foundation for the subsequent installation of transmission components and the implementation of transmission actions.

[0075] The fixed bevel gear 651 is coaxially fixedly arranged on the fixed ring stage 653 , so that the fixed bevel gear 651 can reasonably bear and transmit power without affecting the rotation of the rotating shaft 4 .

[0076] The rotating bevel gear 652 is coaxially fixedly disposed on the driven shaft 631 and forms a good meshing relationship with the fixed bevel gear 651 .

[0077] When the rotating shaft 4 drives the rotating drum 62 to rotate through the coaxial transmission, it can drive the driven shaft 631 to revolve in the circumferential direction, and then drive the rotating bevel gear 652 to move circumferentially along the fixed bevel gear 651. During this process, the rotating bevel gear 652 can drive the driven shaft 631 to rotate, and then the driven shaft 631 drives the stirring plate 63 to rotate around the driven shaft 631, so that the stirring roller group can stir the filler 3.

[0078] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
