Description

Technical Field

[0001] This application relates to the field of material mixing technology, specifically to a solid-liquid material mixing and stirring device. Background Technology

[0002] In the food processing industry, sauce preparation is a crucial step. Sauce preparation requires mixing and stirring various raw materials (basic ingredients, seasonings, auxiliary materials, etc.) to form a finished sauce with a uniform texture and blended flavors. The core of this process is to use mixing equipment to ensure that all materials are fully mixed.

[0003] In order to achieve uniform mixing of solid and liquid materials in sauces and ensure the taste and quality of sauces, existing mixing devices generally adopt a multi-blade combination structure. When this type of mixing device is in use, the mixing shaft drives the blades to rotate, which can form a multi-directional and multi-angle mixing effect on solid and liquid materials, thereby improving mixing efficiency and mixing quality.

[0004] Referring to Chinese invention patent application CN119746668A, entitled "A Stirring Device for High-Viscosity Sauces", it includes a main stirring shaft and multiple layers of stirring components arranged at intervals along the axial direction. Each layer of stirring components consists of multiple stirring blades extending radially, and the blades of adjacent two layers of stirring components are staggered in the circumferential direction. This design, through the staggered arrangement of the blades in space, can form a complex material flow field during the stirring process, promote the bidirectional movement of solid and liquid materials in the radial and axial directions, effectively improve the material stratification problem that is easily caused by stirring in one direction, and significantly improve the mixing uniformity.

[0005] However, while this design, which uses staggered blades to agitate materials, improves agitation efficiency and mixing quality, it also presents significant challenges for cleaning the agitator in actual use. To ensure effective agitation, the spiral directions of the upper and lower blades are typically opposite, leading to blades intersecting and obstructing each other. Furthermore, since marinades often contain viscous components such as oils and colloids, using water to clean the agitator results in reduced cleaning effectiveness as the oil dissolves into the cleaning solution, while also wasting a significant amount of the solution. Therefore, existing technologies typically use spray guns to clean this type of agitator. However, due to the mutual obstruction between blades, some areas of the blades cannot be directly exposed to the spray range of the cleaning equipment, resulting in incomplete cleaning of these obstructed areas and creating numerous cleaning dead zones. This necessitates constant manual adjustment of the cleaning nozzle direction to complete the cleaning of the agitator. Summary of the Invention

[0006] In view of this, this application provides a solid-liquid material mixing and stirring device to solve the problem of cleaning dead zones caused by the mutual obstruction of stirring blades.

[0007] To solve the above-mentioned technical problems, this application provides a solid-liquid material mixing and stirring device, including a stirring tank and a stirring shaft rotatably connected inside the stirring tank. A motor for driving the stirring shaft is provided on the outside of the stirring tank. Two turntables are rotatably connected inside the stirring tank, and a first stirring blade is disposed between the two turntables. The ends of the first stirring blade are fixedly connected to the corresponding turntables on the same side. The left turntable is fixedly connected to the stirring shaft. A rotating sleeve is fitted on the outside of the stirring shaft. A through hole rotatably connected to the rotating sleeve is provided in the middle of the right turntable. A second stirring blade that cooperates with the first stirring blade is provided on the outside of the rotating sleeve. The first and second stirring blades have the same spiral direction. A transmission assembly is provided on the outside of the stirring tank. Two arc-shaped groove plates are provided inside the stirring tank. The diameter of the lower edge of the arc-shaped groove plates is equal to the diameter of the bottom of the stirring tank. Spray pipes are installed inside each arc-shaped groove plate via connectors, and cleaning nozzles are provided at the openings on the outside of the spray pipes.

[0008] By adopting the above technical solution, the stirring shaft rotates under the drive of the motor, which in turn causes the rotating disc and the first stirring blade between the two discs to rotate together, thereby achieving the stirring operation of the material inside the stirring tank. Simultaneously, through the action of the transmission component, the rotating sleeve can be driven to rotate synchronously in opposite directions with the stirring shaft, thus causing the second stirring blade on the outside of the rotating sleeve to rotate synchronously in opposite directions with the first stirring blade. Since the spiral direction of the second stirring blade and the first stirring blade is consistent, when they rotate synchronously in opposite directions, their conveying directions of the material are opposite, thereby generating a bidirectional driving force on the material inside the stirring tank. These two opposing forces create complex material disturbance within the stirring tank, breaking the original static distribution of the material and causing it to move vertically, horizontally, and vertically. The upward, intersecting, penetrating, and mixing process effectively avoids localized aggregation of materials caused by unidirectional flow, ultimately achieving uniform and thorough mixing of materials within the mixing tank and significantly reducing the possibility of insufficient local mixing. After mixing is complete, the motor drives the mixing shaft to rotate in the opposite direction, causing the first and second mixing blades to rotate to their mating positions. On the one hand, this reduces structural obstruction during material discharge, allowing materials to converge towards the discharge port along a regular path, accelerating discharge speed and reducing residue. On the other hand, the regular structural shape reduces gaps and dead angles between mixing components, creating favorable conditions for subsequent cleaning operations and avoiding cleaning blind spots caused by structural intersections. This facilitates rapid and automatic cleaning of the internal structure of the mixing tank, improving cleaning efficiency and cleanliness.

[0009] Optionally, the second stirring blade has blades evenly arranged in a spiral on the side away from the stirring shaft, and the first stirring blade has clearance grooves evenly arranged in a spiral on the side close to the stirring shaft, corresponding to the blade positions.

[0010] By adopting the above technical solution, during the stirring process, the blades on the second stirring plate and the clearance grooves on the first stirring plate cooperate with each other. When the two move relative to each other, the blades can penetrate into the material near the clearance grooves. The cooperation between the blades and the clearance grooves not only breaks the agglomeration of the materials, but also expands the dispersion range of the materials through continuous relative movement, reducing the unevenness of local components caused by agglomeration. This process accelerates the interface contact and fusion between different materials, and while improving the stirring efficiency, it further enhances the stirring effect, ultimately ensuring that the components in the marinade can be evenly mixed, and ensuring that the components of the final marinade are evenly mixed.

[0011] Optionally, the first stirring plate has two connecting rods inside, and the connecting rods are both located between the two turntables.

[0012] By adopting the above technical solution, the connecting rod can support the first stirring plate, reduce the possibility of deformation of the first stirring plate due to excessive force, and ensure that the first stirring plate can carry out stirring work stably.

[0013] Optionally, the connector includes a T-shaped rod disposed inside the arc-shaped groove plate, the upper end of each T-shaped rod being vertically slidably connected to a sliding sleeve, the outer side of each sliding sleeve being vertically slidably connected to a slider, and a spray pipe being rotatably connected between two sliders located inside the same arc-shaped groove plate.

[0014] By adopting the above technical solution, during cleaning, the external cleaning fluid is pumped into the spray pipe through the pipeline and sprayed evenly through the cleaning nozzle at the end of the spray pipe, forming a rinsing water flow with appropriate coverage. Since there are no obvious cross-obstructions inside the mixing tank, the dead corners inside the mixing tank can be effectively reduced during cleaning, realizing automatic cleaning of the internal structure of the mixing tank, improving the flushing ability of the cleaning fluid to stubborn residues, and significantly optimizing the cleaning effect.

[0015] Optionally, the upper edge of the arc-shaped groove plate is provided with a circular protrusion, and the outer side of the spray pipe is provided with a locking block that engages with the circular protrusion to facilitate the fixing of the spray pipe.

[0016] Optionally, the upper end of each of the arc-shaped groove plates is hinged with a protective plate, and each of the protective plates has a slot at its edge, which can engage with a circular protrusion on the same side.

[0017] By adopting the above technical solution, before the equipment is used, the spray pipe is vertically retracted into the internal space of the arc-shaped groove plate on the same side, and the protective plate is closed, which can provide reliable protection for the spray pipe, avoid material splashing during the mixing operation from causing pollution or damage to the spray pipe, and at the same time reduce the corrosion of the spray pipe by the external environment and extend its service life.

[0018] Optionally, the transmission assembly includes a cylinder and a transmission gear. The cylinder is located on the outside of the mixing tank, and the transmission gear is rotatably connected to the telescopic end of the cylinder. Both the right end of the mixing shaft and the rotating sleeve are provided with bevel gears, and both bevel gears can mesh with the transmission gear to facilitate the transmission of power from the mixing shaft to the rotating sleeve.

[0019] Optionally, an annular groove is provided on the right side of the rotating sleeve, and a transmission ring is axially slidably connected in the annular groove. The bevel gear at the end of the stirring shaft is provided with ratchet teeth that cooperate with the transmission ring, and a spring that abuts against the transmission ring is provided inside the annular groove.

[0020] By adopting the above technical solution, after the two bevel gears disengage, on the one hand, the rotating sleeve can rotate synchronously and in the same direction with the drive shaft when the transmission ring engages with the ratchet, and on the other hand, it can play a positioning role in the engagement of the first stirring plate and the second stirring plate.

[0021] Optionally, the upper end of the mixing tank is hinged to a cover plate for sealing the mixing tank. When the cover plate is closed, it can prevent the external environment from contaminating the material during mixing.

[0022] Optionally, a discharge pipe is provided at the discharge port on the outside of the mixing tank, and a valve for controlling the opening and closing of the discharge pipe is connected in series inside the discharge pipe.

[0023] By adopting the above technical solution, the mixed material can be discharged smoothly and completely from the discharge pipe.

[0024] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. Excellent mixing effect, with materials mixed evenly and thoroughly. The device uses the synchronous counter-rotation of the first and second stirring blades, and the opposite conveying directions formed by their same spiral direction, to promote multi-directional convection of materials, achieving full mixing in the up-down and left-right directions. At the same time, the blades of the second stirring blade cooperate with the clearance groove of the first stirring blade to effectively break up clumps of materials, eliminate agglomeration forces, expand the material dispersion range, reduce local incomplete mixing, significantly improve mixing efficiency and effect, and ensure that all components of the marinade are evenly blended.

[0025] 2. Smooth and thorough discharge, facilitating subsequent cleaning operations. After mixing, the first and second mixing blades can precisely cooperate to form a continuous spiral blade structure. Under synchronous and co-directional rotation, the material can be smoothly pushed to the discharge pipe, reducing residue in the tank and accelerating the discharge speed. This spiral blade structure also reduces the gaps and dead angles between the mixing components. Combined with the deployable spray pipe cleaning mechanism, the rinsing water can fully contact the surface of each component in the tank, enhancing the rinsing effect on stubborn residues, achieving rapid and automatic cleaning of the mixing tank, and improving cleaning efficiency and cleanliness.

[0026] 3. When not in operation, the spray pipes of the cleaning mechanism retract into the arc-shaped groove plate, and are reliably protected by the engagement of the protective plate and the circular protrusion. While achieving automatic cleaning, it can also prevent the cleaning mechanism from being contaminated by materials and external corrosion, thus extending the service life of the equipment.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will be combined with the embodiments of this application. Figures 1-9 The technical solutions of the embodiments of this application are clearly and completely described herein. All other embodiments obtained by those skilled in the art based on the described embodiments are within the scope of protection of this application.

[0030] Reference Figure 1 and Figure 2 This embodiment provides a solid-liquid material mixing and stirring device, including a stirring tank 1, a stirring mechanism, and a cleaning mechanism. The upper end of the stirring tank 1 is hinged to a cover plate 8 for sealing the stirring tank 1, preventing external environmental contamination of the material during stirring. A discharge pipe 9 is provided at the discharge port on the outside of the stirring tank 1, and a valve for controlling the opening and closing of the discharge pipe 9 is connected in series inside the discharge pipe 9. The stirring mechanism is located inside the stirring tank 1 for stirring the material within the stirring tank 1. Two sets of cleaning mechanisms are respectively located on the front and rear inner walls of the stirring tank 1, and the cleaning mechanisms are used to clean the inside of the stirring tank 1.

[0031] Reference Figure 2 , Figure 3 and Figure 5 The stirring mechanism includes a stirring shaft 101, a turntable 2, a first stirring blade 3, a rotating sleeve 4, a second stirring blade 41, and a transmission assembly 5. The stirring shaft 101 is rotatably connected to the inside of the stirring tank 1. One end of the stirring shaft 101 extends to the outside of the stirring tank 1 and is connected to the output shaft of a motor 102 located on the outside of the stirring tank 1 via a coupling. The two turntables 2 are rotatably connected to the left and right ends inside the stirring tank 1, respectively. The first stirring blade 3 is located between the two turntables 2, and the ends of the first stirring blade 3 are fixedly connected to the corresponding turntable 2 on the same side. A connecting rod 32 is provided through the inside of the first stirring blade 3, and the ends of the two connecting rods 32 are fixedly connected to the corresponding turntable 2 on the same side. The turntable 2 is fixedly connected; the center of the left turntable 2 is fixedly connected to the stirring shaft 101, and the center of the right turntable 2 is provided with a through hole that is rotatably connected to the rotating sleeve 4. The second stirring blade 41 is disposed on the outside of the rotating sleeve 4. The first stirring blade 3 and the second stirring blade 41 have the same spiral direction. The side of the second stirring blade 41 away from the stirring shaft 101 is evenly provided with blades 411 in a spiral shape. The side of the first stirring blade 3 close to the stirring shaft 101 is evenly provided with clearance grooves 31 in a spiral shape that correspond to the position of the blades 411. The transmission assembly 5 is disposed on the outside of the stirring tank 1. The transmission assembly 5 is used to transmit the power of the stirring shaft 101 to the rotating sleeve 4.

[0032] In use, first pour the solid and liquid materials required for marinating the sauce into the mixing tank 1 in proportion. Then start the motor 102. The power of the motor 102 is transmitted to the mixing shaft 101 through the coupling, which drives the mixing shaft 101 to rotate. In turn, the mixing shaft 101 drives the turntable 2 and the first mixing blade 3 between the two turntables 2 to rotate together, thereby realizing the mixing operation of the materials inside the mixing tank 1.

[0033] Two connecting rods 32 are installed inside the first stirring plate 3, which can provide reliable support for the first stirring plate 3. During the stirring process, the material will generate a certain resistance to the first stirring plate 3, and the connecting rods 32 can effectively disperse the stress caused by this resistance, reduce the possibility of deformation of the first stirring plate 3 due to excessive force, and ensure that the first stirring plate 3 can carry out stirring work stably.

[0034] While the stirring shaft 101 rotates, the transmission assembly 5 drives the rotating sleeve 4 to rotate synchronously in the opposite direction to the stirring shaft 101. This causes the second stirring blade 41 on the outer side of the rotating sleeve 4 to rotate synchronously in the opposite direction to the first stirring blade 3. Since the second stirring blade 41 and the first stirring blade 3 have the same spiral direction, their material conveying directions are exactly opposite when they rotate synchronously in the opposite direction (see reference). Figure 7 This opposite conveying action will cause the material in the mixing tank 1 to form a complex convection motion, and the material will mix with each other in the up-down and left-right directions, so that the material in the mixing tank 1 will be mixed more evenly and thoroughly, reducing the probability of insufficient mixing in some areas. During the mixing process, the blades 411 on the second mixing plate 41 and the clearance groove 31 on the first mixing plate 3 cooperate with each other. When the two move relative to each other, the blades 411 can penetrate into the material near the clearance groove 31 to effectively break up any clumps of material that may appear in the mixing tank 1. This can break up the agglomeration force between materials, disperse the clumps, promote full contact and fusion between various materials, further improve the mixing efficiency of the materials, and enhance the mixing effect, ensuring that the components of the final marinade are mixed evenly.

[0035] After the mixing operation is completed, the motor 102 drives the mixing shaft 101 to rotate in the opposite direction via the coupling, causing the first mixing blade 3 and the second mixing blade 41 to rotate to the mating position (see reference). Figure 2 At this time, the blades 411 on the second stirring plate 41 are precisely embedded in the clearance groove 31 of the first stirring plate 3, and the two fit together to form a continuous spiral plate. Subsequently, under the coordinated action of the transmission component 5, the stirring shaft 101 drives the rotating sleeve 4 to rotate synchronously and in the same direction. Under the continuous rotation of the spiral blades, the material in the stirring tank 1 is smoothly pushed to the discharge port. At the same time, the valve on the discharge pipe 9 is opened. Under the continuous rotation of the above-mentioned spiral conveying structure, the material in the stirring tank 1 is smoothly pushed to the discharge port of the discharge pipe 9, so that the stirred material can be discharged smoothly and thoroughly from the discharge pipe 9. At the same time, it is conducive to the rapid and automatic cleaning of the internal mechanism of the stirring tank 1.

[0036] Reference Figure 1 , Figure 3 , Figure 4 and Figure 8The transmission assembly 5 includes a bevel gear 51, a cylinder 52, and a transmission gear 53. The bevel gear 51 is respectively located at the right end of the stirring shaft 101 and the rotating sleeve 4. The cylinder 52 is located on the outside of the stirring tank 1. The transmission gear 53 is rotatably connected to the telescopic end of the cylinder 52. The two bevel gears 51 can be connected by transmission gear 53. A transmission ring 421 is axially slidably connected in the annular groove 42 located on the right side of the rotating sleeve 4. The bevel gear 51 at the end of the stirring shaft 101 has a ratchet 511 in the middle that cooperates with the transmission ring 421. A spring 422 that abuts against the transmission ring 421 is located inside the annular groove 42.

[0037] When the stirring shaft 101 rotates clockwise, it drives the bevel gear 51 at the right end of the stirring shaft 101 to rotate clockwise. At this time, the cylinder 52 drives the transmission gear 53 to move down. The two bevel gears 51 are transmitted through the transmission gear 53. The clockwise rotation of the stirring shaft 101 can drive the rotating sleeve 4 to rotate in the opposite direction relative to the stirring shaft 101 through the cooperation of the bevel gear 51 and the transmission gear 53. At the same time, the ratchet 511 in the middle of the bevel gear 51 cooperates with the inclined surface of the end face of the transmission ring 421, so that the transmission ring 421 can overcome the elastic force of the spring 422 and retract into the annular groove 42 on the right side of the rotating sleeve 4, ensuring the normal rotation of the stirring shaft 101 and the rotating sleeve 4.

[0038] When the stirring shaft 101 rotates counterclockwise, the cylinder 52 drives the transmission gear 53 to move upward, and the transmission gear 53 separates from the two bevel gears 51. At this time, the two bevel gears 51 disengage from the transmission, the stirring shaft 101 continues to rotate, while the rotating sleeve 4 remains stationary. When the ratchet 511 in the middle of the bevel gear 51 engages with the plane of the end face of the transmission ring 421, the blades 411 on the second stirring plate 41 are located in the clearance groove 31 on the first stirring plate 3. The first stirring plate 3 and the second stirring plate 41 form a spiral plate. Through the engagement of the ratchet 511 and the transmission ring 421, the rotating sleeve 4 is driven to rotate synchronously and in the same direction as the stirring shaft 101, which facilitates the subsequent cleaning of the first stirring plate 3 and the second stirring plate 41.

[0039] Reference Figure 2 , Figure 5 , Figure 6 and Figure 9The cleaning mechanism includes two arc-shaped trough plates 6, connecting parts, and spray pipes 7. The arc-shaped trough plates 6 are respectively located on the front and rear inner walls of the mixing tank 1. The connecting parts are located inside the arc-shaped trough plates 6. The connecting parts include a T-shaped rod 61, a sliding sleeve 62, and a slider 63. The T-shaped rod 61 is located inside the arc-shaped trough plate 6, the sliding sleeve 62 is vertically slidably connected to the outside of the T-shaped rod 61, and the slider 63 is vertically slidably connected to the outside of the sliding sleeve 62. The spray pipe 7 is rotatably connected between the two sliders 63 located inside the same arc-shaped trough plate 6. Each opening on the outside of the spray pipe 7 is equipped with a cleaning nozzle 71. The upper edge of each arc-shaped trough plate 6 is provided with a circular protrusion 64, and the outer surface of each spray pipe 7 is provided with a locking block 72 that engages with the circular protrusion 64. Each upper end of each arc-shaped trough plate 6 is hinged with a protective plate 65, and the edge of the protective plate 65 is provided with a locking groove 651 that engages with the circular protrusion 64.

[0040] Before use, the T-shaped rod 61 and the sliding sleeve 62 are in a retracted state, the slider 63 is located at the bottom of the arc-shaped trough plate 6, and the spray pipe 7 is vertically retracted into the internal space of the arc-shaped trough plate 6 on the same side. At this time, the protective plate 65 at the upper end of the arc-shaped trough plate 6 is in a closed state, and the groove 651 on the edge of the protective plate 65 is tightly engaged with the corresponding circular protrusion 64 on the same side. Through this structural cooperation, reliable protection can be provided for the spray pipe 7 inside the arc-shaped trough plate 6, avoiding material splashing during the mixing operation and preventing contamination or damage to the spray pipe 7. At the same time, it reduces the corrosion of the spray pipe 7 by the external environment and extends its service life. After the materials are mixed and stirred, when entering the cleaning process, first open the protective plate 65, move the spray pipe 7 upwards so that it is completely removed from the arc-shaped groove plate 6, then rotate the spray pipe 7 90° and make the locking block 72 at the lower end of the spray pipe 7 engage with the circular protrusion 64 to achieve a stable fixation of the spray pipe 7, ensuring that the spray pipe 7 will not shift its position due to its own weight or liquid impact during the cleaning process. During the cleaning operation, the external cleaning fluid is pumped into the spray pipe 7 through the pipeline and sprayed evenly through the cleaning nozzle 71 at the end of the spray pipe 7, forming a rinsing water flow with appropriate coverage. At the same time, the first stirring plate 3 and the second stirring plate 41 rotate in opposite directions. Since the first stirring plate 3 and the second stirring plate 41 can be combined to form a continuous spiral plate structure, there is no obvious cross-blocking between the first stirring plate 3 and the second stirring plate 41, which can effectively reduce the dead corners inside the mixing tank 1 during cleaning, so that the rinsing water flow can fully contact the inner wall of the mixing tank 1, the surface of the stirring plates and the connection of each component, and thoroughly wash away and remove residual materials.

[0041] This cleaning method not only achieves automatic cleaning of the internal structure of the mixing tank 1, but also enhances the disturbance effect of the water flow through the dynamic movement of the mixing blades, thereby improving the cleaning fluid's ability to flush away stubborn residues and significantly optimizing the cleaning effect.

[0042] Reference Figure 5 and Figure 9 The lower edge of the arc-shaped trough plate 6 is arc-shaped, and the diameter of the lower edge of the arc-shaped trough plate 6 is equal to the diameter of the arc at the bottom of the mixing tank 1. During mixing, the first stirring plate 3 can contact the lower edge of the arc-shaped trough plate 6, which makes the mixing of materials inside the mixing tank 1 more thorough.

[0043] When this application is used, the motor 102 is started, which drives the stirring shaft 101 to rotate via the coupling, causing the turntable 2 and the first stirring blade 3 to operate. At the same time, the bevel gear 51 at the right end of the stirring shaft 101 is driven by the bevel gear 51 at the right end of the rotating sleeve 4 through the transmission gear 53, causing the rotating sleeve 4 to rotate in the opposite direction. The ratchet 511 of the bevel gear 51 engages with the inclined surface of the transmission ring 421, causing the transmission ring 421 to contract, ensuring that the rotating sleeve 4 rotates normally, allowing the outer second stirring blade 41 to rotate in the opposite direction synchronously with the first stirring blade 3, thereby improving the uniformity of stirring. Furthermore, the blade 411 of the second stirring blade 41 engages with the clearance groove 31 of the first stirring blade 3 to break up clumps of material and improve efficiency.

[0044] During stirring, the T-shaped rod 61 and the sliding sleeve 62 retract, the slider 63 is at the bottom of the arc-shaped groove plate 6, the spray pipe 7 retracts into it, the protective plate 65 closes and the slot 651 engages with the circular protrusion 64 for protection.

[0045] After mixing is completed, cylinder 52 drives transmission gear 53 to move upward, separating it from the two bevel gears 51. Rotating sleeve 4 is stationary. When the ratchet 511 of bevel gear 51 engages with the plane of transmission ring 421, the two stirring blades form a spiral blade, which rotates in the same direction as stirring shaft 101. Motor 102 drives stirring shaft 101 to rotate in the opposite direction, opening the valve of discharge pipe 9. The material is pushed out of discharge pipe 9 by the spiral blade.

[0046] During cleaning, the spray pipe 7 is moved upward and rotated 90° so that the locking block 72 is engaged and fixed with the circular protrusion 64. The external cleaning liquid is sprayed out from the cleaning nozzle 71 through the spray pipe 7. At the same time, the two stirring blades rotate in opposite directions to complete the automatic cleaning. The spiral blade shape reduces dead corners and improves the cleaning effect.

[0047] The implementation principle of a solid-liquid material mixing and stirring device according to an embodiment of this application is as follows: When in use, open the cover plate 8, pour the solid and liquid materials required for marinating the sauce into the mixing tank 1 in proportion, and then close the cover plate 8; then start the motor 102, drive the mixing shaft 101 to rotate through the coupling, and then drive the turntable 2 and the first mixing blade 3 between the two turntables 2 to rotate, so as to realize the mixing operation of the materials inside the mixing tank 1.

[0048] While the stirring shaft 101 rotates, the bevel gear 51 at the right end of the stirring shaft 101 is driven by the transmission gear 53 to the bevel gear 51 at the right end of the rotating sleeve 4. The rotation of the stirring shaft 101 can drive the rotating sleeve 4 to rotate in the opposite direction relative to the stirring shaft 101 through the cooperation of the bevel gear 51 and the transmission gear 53. At the same time, the ratchet 511 in the middle of the bevel gear 51 cooperates with the inclined surface of the end face of the transmission ring 421, so that the transmission ring 421 can overcome the elastic force of the spring 422 and retract into the annular groove 42 on the right side of the rotating sleeve 4, ensuring the normal rotation of the stirring shaft 101 and the rotating sleeve 4, so that the second stirring blade 41 on the outer side of the rotating sleeve 4 rotates synchronously in the opposite direction with the first stirring blade 3. Since the spiral direction of the two is the same, the conveying direction is opposite when rotating synchronously in the opposite direction, which can make the material in the stirring tank 1 more even and thorough. During the stirring process, the blades 411 on the second stirring blade 41 cooperate with the clearance groove 31 on the first stirring blade 3 to break up the clumps of material in the stirring tank 1, promote the fusion of various materials, and further improve the stirring efficiency and effect.

[0049] After stirring is completed, cylinder 52 drives transmission gear 53 to move upward, and transmission gear 53 separates from two bevel gears 51. At this time, the two bevel gears 51 disengage from the transmission, and stirring shaft 101 continues to rotate while rotating sleeve 4 remains stationary. When the ratchet 511 in the middle of bevel gear 51 engages with the plane of the end face of transmission ring 421, the blades 411 on the second stirring blade 41 are located in the clearance groove 31 on the first stirring blade 3, and the two form a spiral blade. Through the engagement of ratchet 511 and transmission ring 421, the rotating sleeve 4 and stirring shaft 101 rotate synchronously and in the same direction, so as to clean the first stirring blade 3 and the second stirring blade 41 in the future. Motor 102 drives stirring shaft 101 to rotate in the opposite direction through coupling. Stirring shaft 101 drives rotating sleeve 4 to rotate synchronously and in the same direction. At this time, the valve on the outside of discharge pipe 9 is opened. Under the rotation of spiral blade, the material in stirring tank 1 is pushed to the vicinity of discharge pipe 9 and finally discharged from discharge pipe 9.

[0050] During stirring, the T-shaped rod 61 and the sliding sleeve 62 are in a retracted state, the slider 63 is located at the bottom of the arc-shaped groove plate 6, the spray pipe 7 is vertically retracted inside the arc-shaped groove plate 6 on the same side, the protective plate 65 at the upper end of the arc-shaped groove plate 6 is in a closed state, and the groove 651 on the edge of the protective plate 65 engages with the corresponding circular protrusion 64 on the same side, thereby protecting the spray pipe 7 inside the arc-shaped groove plate 6.

[0051] After the materials are mixed and stirred, the protective plate 65 is opened, the spray pipe 7 is moved upward and removed from the arc-shaped trough plate 6, and then the spray pipe 7 is rotated 90° so that the locking block 72 at the lower end of the spray pipe 7 engages with the circular protrusion 64 to fix the spray pipe 7. External cleaning fluid is pumped into the spray pipe 7 through the pipeline and sprayed out from the cleaning nozzle 71 at its end. At the same time, the first stirring plate 3 and the second stirring plate 41 rotate in opposite directions to complete the automatic cleaning of the internal structure of the mixing tank 1. Since the first stirring plate 3 and the second stirring plate 41 can form a spiral plate, the dead corners inside the mixing tank 1 can be greatly reduced during cleaning, and the cleaning effect on the internal structure of the mixing tank 1 can be improved.

[0052] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
