Description

TECHNICAL FIELD

[0001] The application relates to the technical field of material mixing, in particular to a solid-liquid material mixing and stirring device. BACKGROUND

[0002] In the food processing industry, the preparation of sauce is a crucial link. During the preparation of sauce, multiple raw materials (basic food materials, seasonings, auxiliary materials, etc.) need to be mixed and stirred to form a finished sauce with uniform texture and flavor fusion. The core is to enable various materials to be fully mixed through the stirring equipment.

[0003] In order to realize the uniform mixing of solid-liquid materials in the sauce and ensure the taste and quality of the sauce, the stirring device in the prior art generally adopts a multi-blade combined structure. When the stirring device is used, the blades are rotated by the stirring shaft, which can form multi-directional and multi-angle stirring action on the solid-liquid materials, thereby improving the mixing efficiency and mixing quality.

[0004] For example, referring to the Chinese invention patent application with the publication number CN119746668A and the name of a stirring device suitable for high-viscosity sauce, which comprises a main stirring shaft and multiple layers of stirring assemblies arranged along the axial direction. Each layer of stirring assembly is composed of multiple stirring blades extending along the radial direction, and the blades of adjacent two layers of stirring assemblies are staggered in the circumferential direction. This design can form a complex material flow field during stirring by the staggered arrangement of the blades in space, promote the bidirectional movement of solid-liquid materials in the radial and axial directions, and effectively improve the material layering problem caused by single-direction stirring, thereby significantly improving the mixing uniformity.

[0005] However, this design of stirring materials through the staggered structure of the blades can improve the stirring efficiency and mixing quality of the materials, but after actual use, the staggered blades bring great trouble to the subsequent cleaning work of the stirring equipment. In order to ensure the stirring effect, the spiral direction of the upper blades is usually set in the opposite direction of the spiral direction of the lower blades, which causes the blades to be staggered and blocked with each other. Moreover, since the pickled sauce usually contains oil, colloid and other sticky components, when the inside of the stirring device is cleaned by the water storage method, on the one hand, the oil stains dissolved into the cleaning liquid reduce the cleaning effect of the cleaning liquid, and on the other hand, the cleaning liquid is wasted. Therefore, in the prior art, a spray gun is usually used to clean the stirring device. However, due to the mutual blocking of the blades, some areas of the blades cannot be directly exposed to the spray range of the cleaning equipment, which causes the blocked areas of the blades to be not completely cleaned, forming a large number of cleaning dead angles, and the direction of the cleaning spray head needs to be adjusted manually to complete the cleaning of the stirring equipment. SUMMARY

[0006] Therefore, the solid-liquid material mixing and stirring device is provided.

[0007] To solve the above technical problems, the solid-liquid material mixing and stirring device is provided, which comprises a stirring tank and a stirring shaft rotatably connected in the stirring tank.

[0008] Through the above technical scheme, under the driving action of the motor, the stirring shaft rotates, and then drives the stirring shaft, the disc and the first stirring blades between the two discs to rotate, so as to realize the stirring operation of the material in the stirring tank. At the same time, through the action of the transmission assembly, the rotating sleeve and the stirring shaft can be driven to rotate reversely synchronously, and then the second stirring blades outside the rotating sleeve and the first stirring blades are in the reverse rotating state. Since the spiral directions of the second stirring blades and the first stirring blades are consistent, when they rotate reversely synchronously, the conveying directions of the material are opposite, so that the material in the stirring tank is driven in two directions. The two reverse forces form a complex material disturbance in the stirring tank, break the original static distribution of the material, and promote the material to continuously cross, penetrate and mix in the up-down and left-right directions, effectively avoid the local aggregation of the material due to the one-way flow, and finally realize the uniform and complete mixing of the material in the stirring tank, greatly reduce the possibility of insufficient local mixing.

DETAILED DESCRIPTION

[0038] To make the purpose, technical scheme and advantages of the embodiments of the application clearer, the following will​Figures 1-9 The technical solutions of the embodiments of the present application are clearly and completely described. All other embodiments obtained by those skilled in the art based on the described embodiments of the present application belong to the scope of protection of the present application.

[0039] With reference to Figure 1 and Figure 2 , the embodiment provides a solid-liquid material mixing and stirring device, which comprises a stirring tank 1, a stirring mechanism and a cleaning mechanism. The upper end of the stirring tank 1 is hingedly connected with a cover plate 8 for sealing the stirring tank 1, so as to avoid pollution of the material by the external environment during stirring; a discharge pipe 9 is arranged at the discharge port of the outer side of the stirring tank 1, and a valve for controlling the opening and closing of the discharge pipe 9 is arranged in series in the discharge pipe 9; the stirring mechanism is arranged in the interior of the stirring tank 1 and is used for stirring the material in the stirring tank 1; the cleaning mechanism is arranged on the front and rear inner walls of the stirring tank 1 and is used for cleaning the interior of the stirring tank 1.

[0040] With reference to Figure 2 , Figure 3 and Figure 5 , the stirring mechanism comprises a stirring shaft 101, a rotating disc 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 interior of the stirring tank 1, one end of the stirring shaft 101 extends to the outer side of the stirring tank 1 and is connected with the output shaft of a motor 102 arranged on the outer side of the stirring tank 1 through a shaft coupling; two rotating discs 2 are rotatably connected to the left and right ends of the interior of the stirring tank 1, respectively; the first stirring blade 3 is arranged between the two rotating discs 2, the end of the first stirring blade 3 is fixedly connected with the corresponding rotating disc 2 on the same side, and a connecting rod 32 is arranged in the interior of the first stirring blade 3; the ends of the two connecting rods 32 are fixedly connected with the corresponding rotating disc 2 on the same side; the center of the rotating disc 2 on the left side is fixedly connected with the stirring shaft 101, and the center of the rotating disc 2 on the right side is provided with a through hole rotatably connected with the rotating sleeve 4; the second stirring blade 41 is arranged on the outer side of the rotating sleeve 4; the spiral directions of the first stirring blade 3 and the second stirring blade 41 are the same; the side of the second stirring blade 41 away from the stirring shaft 101 is uniformly provided with blades 411 in a spiral shape; the side of the first stirring blade 3 close to the stirring shaft 101 is uniformly provided with avoiding grooves 31 corresponding to the positions of the blades 411 in a spiral shape; the transmission assembly 5 is arranged on the outer side of the stirring tank 1 and is used for transmitting the power of the stirring shaft 101 to the rotating sleeve 4.

[0041] In use, the solid material and the liquid material required for pickling sauce are poured into the stirring tank 1 according to the proportion. Then the motor 102 is started, the power of the motor 102 is transmitted to the stirring shaft 101 through the shaft coupling, the stirring shaft 101 is driven to rotate, and then the stirring shaft 101 drives the rotating disc 2 and the first stirring blade 3 between the two rotating discs 2 to rotate together, so as to realize the stirring operation of the material in the interior of the stirring tank 1.

[0042] The two connecting rods 32 arranged through the first stirring blade 3 can provide reliable support for the first stirring blade 3; during the stirring process, the material will generate a certain resistance to the first stirring blade 3, and the connecting rod 32 can effectively disperse the stress caused by the resistance, reduce the possibility of deformation of the first stirring blade 3 due to excessive stress, and ensure that the first stirring blade 3 can stably perform the stirring work.

[0043] When the stirring shaft 101 rotates, the rotating sleeve 4 can be driven to synchronously and reversely rotate with the stirring shaft 101 through the action of the transmission assembly 5, and then the second stirring blade 41 on the outside of the rotating sleeve 4 can be in a synchronous and reverse rotation state with the first stirring blade 3; since the spiral directions of the second stirring blade 41 and the first stirring blade 3 are the same, the conveying directions of the two are opposite (see Figure 7 ) when they synchronously and reversely rotate; the opposite conveying effect can promote the complex convection movement of the material in the stirring tank 1, and the material is mixed in the up-down and left-right directions, so that the material in the stirring tank 1 is more uniformly and completely stirred, and the probability of insufficient mixing of local material is reduced.

[0044] During the stirring process, the blades 411 on the second stirring blade 41 and the avoidance grooves 31 on the first stirring blade 3 cooperate with each other, and when they move relative to each other, the blades 411 can penetrate into the material near the avoidance grooves 31 to effectively disperse the agglomerated material in the stirring tank 1; the cohesion between the materials can be broken, the agglomerated material can be dispersed, the contact and fusion between various materials can be promoted, the stirring efficiency of the material can be further improved, the stirring effect can be enhanced, and it is ensured that the finally obtained pickling sauce is uniformly mixed.

[0045] After the stirring operation is completed, the motor 102 drives the stirring shaft 101 to reversely rotate through the shaft coupling, so that the first stirring blade 3 and the second stirring blade 41 are rotated to the cooperation position (see Figure 2 ) ; at this time, the blades 411 on the second stirring blade 41 are embedded in the avoidance grooves 31 of the first stirring blade 3, and the two are matched to form a continuous spiral blade.

[0046] Thereafter, under the cooperation of the transmission assembly 5, the stirring shaft 101 drives the rotating sleeve 4 to synchronously and forwardly rotate, and under the continuous rotating action of the spiral blade, the material in the stirring tank 1 is smoothly pushed to the discharge port, and the valve on the discharge pipe 9 is opened. Under the continuous rotating action 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 smoothly and completely discharged from the discharge pipe 9; at the same time, it is beneficial to the rapid and automatic cleaning of the internal mechanism of the subsequent stirring tank 1.

[0047] Refer to Figure 1 , Figure 3 ,Figure 4 and Figure 8 The transmission assembly 5 comprises bevel gears 51, a cylinder 52 and a transmission gear 53; the bevel gears 51 are respectively arranged at the right end of the stirring shaft 101 and the rotating sleeve 4, the cylinder 52 is arranged outside the stirring tank 1, the transmission gear 53 is rotationally connected to the telescopic end of the cylinder 52, and the two bevel gears 51 can be drivingly connected through the transmission gear 53; the transmission ring 421 is axially slidingly connected in the annular groove 42 arranged at the right side of the rotating sleeve 4, and the bevel gear 51 at the end of the stirring shaft 101 is provided with the ratchet 511 matched with the transmission ring 421, and the annular groove 42 is internally provided with the spring 422 abutting against the transmission ring 421.

[0048] When the stirring shaft 101 rotates clockwise, the bevel gear 51 at the right end of the stirring shaft 101 is driven to rotate clockwise, at this time, the cylinder 52 drives the transmission gear 53 to move downward, the two bevel gears 51 are driven through the transmission gear 53, and the clockwise rotation of the stirring shaft 101 can drive the rotating sleeve 4 to reversely rotate relative to the stirring shaft 101 through the cooperation of the bevel gear 51 and the transmission gear 53; meanwhile, the ratchet 511 at the middle part of the bevel gear 51 cooperates with the inclined surface at the end surface of the transmission ring 421, so that the transmission ring 421 can overcome the elastic force of the spring 422 and shrink into the annular groove 42 at the right side of the rotating sleeve 4, thereby ensuring the normal rotation of the stirring shaft 101 and the rotating sleeve 4.

[0049] When the stirring shaft 101 rotates counterclockwise, the cylinder 52 drives the transmission gear 53 to move upward, and the transmission gear 53 is separated from the two bevel gears 51, at this time, the two bevel gears 51 are disconnected, the stirring shaft 101 continues to rotate, and the rotating sleeve 4 remains stationary, when the ratchet 511 at the middle part of the bevel gear 51 cooperates with the flat surface at the end surface of the transmission ring 421, the blades 411 on the second stirring blade 41 are located in the avoiding groove 31 on the first stirring blade 3, the first stirring blade 3 and the second stirring blade 41 form a spiral blade, and the rotating sleeve 4 is driven to synchronously and directionally rotate with the stirring shaft 101 through the cooperation of the ratchet 511 and the transmission ring 421, thereby facilitating the subsequent cleaning of the first stirring blade 3 and the second stirring blade 41.

[0050] Referring to Figure 2 , Figure 5 , Figure 6 and Figure 9The cleaning mechanism comprises arc-shaped groove plates 6, connecting pieces and spray pipes 7. The arc-shaped groove plates 6 are two in number and are arranged on the front and rear inner walls of the stirring tank 1 respectively. The connecting pieces are arranged inside the arc-shaped groove plates 6. The connecting pieces comprise T-shaped rods 61, sliding sleeves 62 and sliding blocks 63. The T-shaped rods 61 are arranged inside the arc-shaped groove plates 6. The sliding sleeves 62 are vertically and slidingly connected to the outer sides of the T-shaped rods 61. The sliding blocks 63 are vertically and slidingly connected to the outer sides of the sliding sleeves 62. The spray pipes 7 are rotationally connected between the two sliding blocks 63 inside the same arc-shaped groove plate 6. The openings on the outer sides of the spray pipes 7 are all provided with cleaning nozzles 71. The upper edges of the arc-shaped groove plates 6 are all provided with circular protrusions 64. The outer sides of the spray pipes 7 are all provided with clamping blocks 72 which are clamped with the circular protrusions 64. The upper ends of the arc-shaped groove plates 6 are all hingedly provided with protective plates 65. The edges of the protective plates 65 are all provided with clamping grooves 651 which are clamped with the circular protrusions 64.

[0051] Before the device is used, the T-shaped rods 61 and the sliding sleeves 62 are kept in a contracted state. The sliding blocks 63 are located at the bottom ends inside the arc-shaped groove plates 6. The spray pipes 7 are vertically and contractedly arranged in the inner spaces of the same-side arc-shaped groove plates 6. At this time, the protective plates 65 at the upper ends of the arc-shaped groove plates 6 are in a closed state. The clamping grooves 651 at the edges of the protective plates 65 are tightly clamped with the corresponding circular protrusions 64 on the same side. Through this structure, the spray pipes 7 inside the arc-shaped groove plates 6 can be reliably protected. The pollution or damage of the spray pipes 7 caused by the splashing of materials during stirring operation can be avoided. Meanwhile, the erosion of the spray pipes 7 by the external environment can be reduced. The service life of the spray pipes 7 can be prolonged.

[0052] When the material mixing and stirring are completed and the cleaning process is entered, the protective plates 65 are first opened. The spray pipes 7 are moved upward so as to be completely moved out of the arc-shaped groove plates 6. Then, the spray pipes 7 are rotated by 90°. The clamping blocks 72 at the lower ends of the spray pipes 7 are clamped with the circular protrusions 64. In this way, the spray pipes 7 are stably fixed. It is ensured that the spray pipes 7 will not be deviated in position due to the gravity or liquid impact force during the cleaning process.

[0053] During the cleaning operation, the external cleaning liquid is pumped into the spray pipes 7 through the pipelines. The cleaning liquid is uniformly sprayed out through the cleaning nozzles 71 at the ends of the spray pipes 7 to form a flushing water flow with a suitable coverage range. Meanwhile, the first stirring blades 3 and the second stirring blades 41 are kept in reverse rotation. Since the first stirring blades 3 and the second stirring blades 41 can be combined into a continuous spiral blade structure, there is no obvious intersection and shielding between the first stirring blades 3 and the second stirring blades 41. The dead angles inside the stirring tank 1 during the cleaning can be effectively reduced. The flushing water flow can fully contact the inner wall of the stirring tank 1, the surfaces of the stirring blades and the connecting portions of various components to completely flush and strip the residual materials.

[0054] This cleaning method not only realizes automatic cleaning of the internal structure of the stirring tank 1, but also enhances the disturbance effect of the water flow through the dynamic movement of the stirring blades, improves the flushing ability of the cleaning liquid on stubborn residues, and significantly optimizes the cleaning effect.

[0055] Referring to Figure 5 and Figure 9 The lower edge surface of the arc-shaped groove plate 6 is arc-shaped, and the diameter of the lower edge surface of the arc-shaped groove plate 6 is equal to the diameter of the arc-shaped bottom of the stirring tank 1. During stirring, the first stirring blade 3 can contact the lower edge surface of the arc-shaped groove plate 6, and the material in the stirring tank 1 can be stirred more fully.

[0056] When the application is used, the motor 102 is started to drive the stirring shaft 101 to rotate, so that the rotating disc 2 and the first stirring blade 3 operate. At the same time, the conical gear 51 at the right end of the stirring shaft 101 drives the conical gear 51 at the right end of the rotating sleeve 4 through the transmission gear 53, so that the rotating sleeve 4 rotates in the opposite direction. The engagement of the ratchet teeth 511 of the conical gear 51 and the inclined surface of the transmission ring 421 causes the transmission ring 421 to contract, ensuring the normal rotation of the rotating sleeve 4, and allowing the outer second stirring blade 41 to rotate in the opposite direction synchronously with the first stirring blade 3, improving the uniformity of stirring. The second stirring blade 41 and the first stirring blade 3 are in cooperation with the first stirring blade 3, which can disperse the agglomerated material and improve the efficiency.

[0057] During stirring, the T-shaped rod 61 and the sliding sleeve 62 are contracted, the sliding block 63 is at the bottom end of the arc-shaped groove plate 6, the spray pipe 7 is contracted therein, the protection plate 65 is closed and the clamping groove 651 is clamped with the circular convex strip 64.

[0058] After stirring is completed, the air cylinder 52 drives the transmission gear 53 to move upwards, so that it is separated from the two conical gears 51, and the rotating sleeve 4 is stationary. When the ratchet teeth 511 of the conical gear 51 are in cooperation with the flat surface of the transmission ring 421, the two stirring blades form a spiral blade, which rotates in the same direction with the stirring shaft 101. The motor 102 drives the stirring shaft 101 to rotate in the opposite direction, the valve of the discharge pipe 9 is opened, and the material is pushed out from the discharge pipe 9 through the spiral blade.

[0059] During cleaning, the spray pipe 7 is moved upwards and rotated by 90°, so that the clamping block 72 is clamped with the circular convex strip 64. The external cleaning liquid is sprayed from the cleaning nozzle 71 through the spray pipe 7, and the two stirring blades rotate in the opposite direction, so that the automatic cleaning is completed. The spiral blade shape reduces the dead angle and improves the cleaning effect.

[0060] The implementation principle of the solid-liquid material mixing and stirring device according to the embodiment of the application is as follows:

[0061] In use, open the cover plate 8, pour the solid and liquid materials required for pickling sauce into the stirring tank 1 according to the proportion, and then close the cover plate 8; then start the motor 102 to drive the stirring shaft 101 to rotate through the coupling, and then drive the rotating disc 2 and the first stirring blade 3 between the two rotating discs 2 to rotate, so as to realize the stirring operation of the materials in the stirring tank 1.

[0062] When the stirring shaft 101 rotates, the bevel gear 51 at the right end of the stirring shaft 101 drives the bevel gear 51 at the right end of the rotating sleeve 4 through the transmission gear 53, and the rotation of the stirring shaft 101 can drive the rotating sleeve 4 to rotate reversely 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 teeth 511 in the middle of the bevel gear 51 cooperate with the inclined surface of the end surface of the transmission ring 421, so that the transmission ring 421 can overcome the elastic force of the spring 422 and shrink 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 outside of the rotating sleeve 4 rotates reversely synchronously with the first stirring blade 3. Since the spiral directions of the two are the same, the conveying directions are opposite when they rotate reversely synchronously, which can make the materials in the stirring tank 1 more uniform and thorough. During the stirring process, the blades 411 on the second stirring blade 41 cooperate with the avoidance grooves 31 on the first stirring blade 3, which can scatter the materials in the stirring tank 1 into groups, promote the fusion of various materials, and further improve the stirring efficiency and effect.

[0063] After the stirring is completed, the air cylinder 52 drives the transmission gear 53 to move upwards, and the transmission gear 53 is separated from the two bevel gears 51. At this time, the two bevel gears 51 are disconnected, the stirring shaft 101 continues to rotate, and the rotating sleeve 4 remains stationary; when the ratchet teeth 511 in the middle of the bevel gear 51 cooperate with the flat surface of the end surface of the transmission ring 421, the blades 411 on the second stirring blade 41 are located in the avoidance grooves 31 on the first stirring blade 3, and the two form a spiral blade. Through the cooperation of the ratchet teeth 511 and the transmission ring 421, the rotating sleeve 4 and the stirring shaft 101 rotate synchronously and in the same direction, so as to facilitate the subsequent cleaning of the first stirring blade 3 and the second stirring blade 41; the motor 102 drives the stirring shaft 101 to rotate reversely through the coupling, and the stirring shaft 101 drives the rotating sleeve 4 to rotate synchronously and in the same direction. At this time, the valve on the outside of the discharge pipe 9 is opened, and the materials in the stirring tank 1 are pushed to the vicinity of the discharge pipe 9 under the action of the rotation of the spiral blade, and finally discharged from the discharge pipe 9.

[0064] During stirring, the T-shaped rod 61 and the sliding sleeve 62 are in a retracted state, the sliding block 63 is located at the bottom end inside the arc-shaped groove plate 6, the spray pipe 7 is vertically retracted inside the arc-shaped groove plate 6 on the same side, and the protective plate 65 at the upper end of the arc-shaped groove plate 6 is in a closed state. The clamping groove 651 on the edge of the protective plate 65 cooperates with the corresponding circular convex strip 64 on the same side to be clamped, thereby protecting the spray pipe 7 inside the arc-shaped groove plate 6.

[0065] After the mixing and stirring of the materials are completed, the protection plate 65 is opened, the spraying pipe 7 is moved upward and out of the arc-shaped groove plate 6, then the spraying pipe 7 is rotated by 90°, and the clamping block 72 at the lower end of the spraying pipe 7 is matched and clamped with the circular convex strip 64 to fix the spraying pipe 7. The external cleaning liquid is pumped into the spraying pipe 7 through the pipeline and sprayed out from the cleaning spray head 71 at the end thereof, while the first stirring blade 3 and the second stirring blade 41 are reversely rotated to complete the automatic cleaning of the internal structure of the stirring tank 1. Since the first stirring blade 3 and the second stirring blade 41 can form a spiral blade, the dead angle in the stirring tank 1 during cleaning can be greatly reduced, and the cleaning effect on the internal mechanism of the stirring tank 1 is improved.

[0066] The above describes the preferred embodiments of the present application. It should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered as the protection scope of the present application.
