Technical Field
[0001] This invention relates to the field of porridge mixing technology, specifically to a porridge mixing tank. Background Technology
[0002] In the food processing industry, porridge is a common and nutritious food, and the mixing process is crucial in its production. High-quality porridge requires the ingredients to be fully blended and have a uniform texture, avoiding problems such as clumping, sedimentation, or uneven concentration. This places high demands on the performance of the mixing equipment.
[0003] Currently, most porridge mixing equipment on the market adopts a single-shaft mixing structure, where the mixing blades are usually fixed on a rotating shaft, and the shaft is driven by a motor to achieve mixing. However, this single-shaft mixing method has obvious drawbacks: due to the limited mixing range, the porridge at the bottom and edges of the container is often difficult to mix thoroughly, resulting in incomplete mixing and affecting the overall quality of the porridge. Especially in mass production, the efficiency of single-shaft mixing is low and cannot meet the needs of large-scale production. Summary of the Invention

[0011] 3. Beneficial effects: Compared with the prior art, the technical scheme provided by the present application has the following beneficial effects: The plurality of rotating shafts arranged at equal distances in the circumferential direction of the mounting cylinder are synchronously rotated under the driving of the driving mechanism, and cooperate with the stirring blades to stir the congee in different positions in the cylinder body in all directions and without dead angle, so that the congee can be fully contacted and mixed during the stirring process, and both the thick part at the bottom and the relatively thin part at the top can be uniformly treated, which greatly improves the uniform mixing effect. Compared with single-shaft stirring, the multi-shaft synchronous working can complete the stirring task in a shorter time, greatly improves the working efficiency, and is especially suitable for batch production scenes. The present application has uniform and stable stirring, avoids the situation that the congee is locally overheated or unevenly stressed during the stirring process, and can well maintain the original taste and nutritional ingredients of the congee. The multi-shaft synchronous stirring enables the various raw materials in the congee to be fully mixed, without phenomena such as caking and precipitation, thereby ensuring the consistency and stability of the congee and improving the quality of the product. The lifting mechanism can accurately control the lifting height of the mixing mechanism by the motor one, and can flexibly adjust the immersion depth of the stirring assembly according to the amount of congee in the cylinder body. When the amount of congee is small, the height of the mixing mechanism can be lowered so that the stirring blades can fully contact the congee, and when the amount of congee is large, the height of the mixing mechanism can be raised to avoid excessive pressure on the stirring blades. This flexible adjustment mode not only ensures the stirring effect, but also adapts to different production requirements, is simple and convenient to operate, and does not need complex manual adjustment.

[0019] Referring to the drawings Figs. 1-7 A porridge uniform mixing and stirring cylinder, comprising a cylinder body 1, a lifting mechanism 2 is arranged on one side of the cylinder body 1, a mixing mechanism 3 is arranged on the output end of the lifting mechanism 2, the mixing mechanism 3 comprises a mounting cylinder 31, a plurality of rotating shafts 34 are arranged at equal distances in the circumferential direction of the mounting cylinder 31, a plurality of stirring blades 35 are fixed on each rotating shaft 34, a mounting groove 37 is formed in the mounting cylinder 31, and a driving mechanism 36 is arranged in the mounting groove 37. The driving mechanism 36 drives a plurality of rotating shafts 34 to rotate at the same time.
[0020] The driving mechanism 36 comprises a second motor 361, a driving bevel gear 362 and a driven bevel gear 363. The second motor 361 is fixed in the mounting groove 37. The driving bevel gear 362 is sleeved on the output shaft of the second motor 361 and is rotatably installed in the mounting groove 37. The driven bevel gear 363 is correspondingly sleeved on one end of each rotating shaft 34 extending into the mounting groove 37, and each driven bevel gear 363 is in meshing connection with the driving bevel gear 362.
[0021] A mounting hole 365 is formed in the mounting cylinder 31 and is matched with the number of rotating shafts 34. The rotating shaft 34 is arranged in the mounting hole 365, and a bearing 364 is arranged between the rotating shaft 34 and the mounting hole 365. A sealing cover 366 is sleeved on the position of the outer side of the mounting cylinder 31 corresponding to the mounting hole 365, and the sealing cover 366 wraps the connecting part of the rotating shaft 34 and the mounting cylinder 31. The sealing cover 366 tightly wraps the connecting part of the rotating shaft 34 and the mounting cylinder 31, which can effectively prevent the porridge from penetrating into the mounting hole 365 during stirring, and avoid the blockage and damage of the parts caused by the residue of the porridge.
[0022] The lifting mechanism 2 comprises a mounting box 21 arranged on one side of the cylinder body 1, a screw rod 22 rotatably arranged in the mounting box 21, a motor one 23 fixed on the top of the mounting box 21 and used to drive the rotation of the screw rod 22, a threaded sleeve 24 threadedly connected to the screw rod 22, a lifting block 25 fixed to the outer side of the threaded sleeve 24, an active groove 26 arranged on the side of the mounting box 21 close to the cylinder body 1, and a connecting beam 27 connected to the lifting block 25 and passing through the active groove 26, wherein one end of the connecting beam 27 away from the lifting block 25 is connected to a mounting cylinder 31 of the mixing mechanism 3.
[0023] A linear bearing 28 is fixed to the side of the lifting block 25 away from the connecting beam 27, a guide shaft 29 is fixed in the mounting box 21 and parallel to the screw rod 22, and the linear bearing 28 is sleeved on the guide shaft 29 and in sliding fit with the guide shaft 29. The cooperation between the linear bearing 28 and the guide shaft 29 provides accurate guidance for the movement of the lifting block 25, effectively avoiding the possible deviation and shaking during the lifting process. The use of the bearing 364 greatly reduces the friction resistance when the rotating shaft 34 rotates, reduces the wear between components, and prolongs the service life of the equipment. The stable running state makes the equipment less likely to fail during long-term use, reduces the time and cost of maintenance downtime, and ensures the continuity and stability of production. A sealing cover 32 is arranged on the opening of the mounting groove 37 of the mounting cylinder 31, and the sealing cover 32 is fixedly connected to the connecting beam 27 through a connecting rod 33. The sealing cover 32 is fixedly connected to the connecting beam 27 through the connecting rod 33, completely seals the mounting groove 37, prevents the porridge from entering the inside of the mounting groove 37, and protects the precision components such as the driving mechanism 36 from being contaminated. The good sealing performance not only maintains the cleanliness of the inside of the equipment, but also further prolongs the service life of the equipment.
[0024] In addition, the device can not only be used for uniform mixing and stirring of various porridges, but also can replace different types of stirring blades 35 according to different stirring needs, and can be used for mixing of other similar flowable materials, such as sauces and soups. The flexible adjustment function and stable performance make it can adapt to the characteristics and stirring requirements of different materials, have a wide range of applications, increase the practicality and economy of the equipment.
[0025] Working principle: Before work, the equipment needs to be comprehensively checked to ensure that the inside of the cylinder body 1 is clean and free of debris, the components are firmly connected, and the motor one 23, the motor two 361 and other electrical elements are normally powered. Then, the porridge to be uniformly mixed is slowly poured along the inner wall of the cylinder body 1, and attention should be paid to the amount of porridge, which should not exceed two-thirds of the volume of the cylinder body 1, so as not to overflow during stirring.
[0026] After everything is ready, start the device general switch, first operate the lifting mechanism 2. Press the down button, the motor 23 starts immediately, its output shaft drives the screw rod 22 to rotate clockwise in the installation box 21. Because the threaded sleeve 24 is connected with the screw rod 22 through threads, the threaded sleeve 24 will move downward along the axial direction of the screw rod 22 with the lifting block 25. In this process, the linear bearing 28 on the lifting block 25 will slide synchronously along the guide shaft 29 arranged in parallel, which provides stable support and guidance for the lifting block 25, effectively avoiding the left and right shaking or jamming of the lifting block 25 during movement, ensuring smooth and smooth whole process. The lifting block 25 is fixedly connected with the connecting beam 27 through bolts, and the other end of the connecting beam 27 is connected with the installation cylinder 31 of the mixing mechanism 3 through the connecting rod 33, so when the lifting block 25 descends, the connecting beam 27 will drive the installation cylinder 31 to descend synchronously. The operator needs to closely observe the position of the mixing mechanism 3, when the several rotating shafts 34 arranged equidistantly in the circumferential direction of the installation cylinder 31 and the several stirring blades 35 fixed on each rotating shaft 34 are completely immersed in the porridge, and the distance between the stirring blades 35 and the bottom of the cylinder 1 is about 5-10 cm, press the stop button of the lifting mechanism 2, the motor 23 stops working, and the mixing mechanism 3 remains in the current position. Then, start the stirring function of the mixing mechanism 3. The driving mechanism 36 in the installation groove 37 starts to work, the motor 361 is electrified and rotates, and its output shaft drives the driving bevel gear 362 to rotate. The driving bevel gear 362 is meshed with several driven bevel gears 363, and each driven bevel gear 363 is respectively sleeved on the end of the corresponding rotating shaft 34 extending into the installation groove 37, and is fixed in the circumferential direction through key connection, so the rotation of the driving bevel gear 362 drives all the driven bevel gears 363 to rotate synchronously, and then drives all the rotating shafts 34 to rotate at the same speed. The rotating shaft 34 penetrates the installation hole 365 formed in the installation cylinder 31, and the bearing 364 arranged between the rotating shaft 34 and the installation hole 365 is a deep groove ball bearing, the outer ring of which is interference fit with the installation hole 365, and the inner ring is transition fit with the rotating shaft 34, which greatly reduces the frictional resistance of the rotating shaft 34 during rotation, not only ensures the smoothness of the rotating shaft 34, but also reduces the load of the motor 361, and reduces the wear between the rotating shaft 34 and the installation cylinder 31, prolongs the service life of the components. With the rotation of the rotating shaft 34, the stirring blades 35 fixed on the rotating shaft 34 begin to stir the porridge in the cylinder body 1. The porridge of different positions and different consistencies in the cylinder body 1 can be fully mixed. During the stirring process, the sealing cover 366 sleeved outside the mounting cylinder 31 corresponding to the mounting hole 365 position plays an important role. The sealing cover 366 is made of food-grade silica gel material, one end of which is fixed on the outer wall of the mounting cylinder 31 through a clamp, and the other end is tightly attached to the surface of the rotating shaft 34. It can effectively prevent the porridge from seeping into the inside of the mounting cylinder 31 through the mounting hole 365 during the stirring process, avoid the influence of the normal rotation of the rotating shaft 34 caused by the solidification of the porridge in the mounting hole 365, and also prevent the lubricating oil in the inside of the mounting cylinder 31 from leaking into the porridge to cause pollution. In addition, the sealing cover 32 covering the opening of the mounting groove 37 of the mounting cylinder 31 is fixedly connected with the connecting beam 27 through a plurality of connecting rods 33 uniformly distributed in the circumferential direction. A rubber sealing ring is arranged between the contact surface of the sealing cover 32 and the mounting cylinder 31, which can completely seal the mounting groove 37, prevent the porridge splashed during the stirring process from entering the inside of the mounting groove 37, protect the precise components such as the driving mechanism 36 from pollution and damage, and ensure that they can work stably for a long time. According to the type and uniform mixing requirement of the porridge, the stirring time is usually set to 5-15 minutes. When the porridge reaches the uniform mixing standard, press the stop button of the mixing mechanism 3, the motor 2 361 stops rotating, and all the rotating shafts 34 and the stirring blades 35 also stop rotating. Finally, the lifting function of the lifting mechanism 2 is started, the motor 1 23 is reversed, the driving screw 22 is rotated counterclockwise, the threaded sleeve 24 carries the lifting block 25, the connecting beam 27 and the mixing mechanism 3 to move axially upward along the screw 22, until the stirring blades 35 completely separate from the porridge in the cylinder body 1, and the distance from the top of the cylinder body 1 is about 20-30 cm, press the stop button, the motor 1 23 stops working. At this time, the operator can open the discharge valve at the bottom of the cylinder body 1 to discharge the uniformly mixed porridge.
[0027] The above-described embodiments only express certain embodiments of the present application, which are described in detail and specifically, but cannot be understood as limiting the scope of the present application; it should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application; therefore, the protection scope of the present application should be subject to the appended claims.
