Description
Technical Field
[0001] The utility model relates to the technical field of food processing, in particular to a stirring device. Background Art
[0002] In the food processing process, the stirring device is a common tool. It usually consists of one or more stirrers and a cooking tank. The stirrer is used to mix the ingredients evenly during the processing. The design and performance of the stirring device have an important impact on the quality and efficiency of the cooking process.
[0003] The conventional stirring device mainly consists of a motor driving the rotating shaft to rotate, and the stirring blades fixed on the rotating shaft rotate accordingly and stir the materials in the cooking tank. However, this conventional stirring device has the following problems: since the rotating shaft is usually located on the central axis of the cooking pot, the rotation trajectory of the stirring blades is also concentrated in the central area of the cooking tank, and some materials will stick to the inner wall of the cooking tank, making it difficult to stir. Moreover, as the stirring time increases, the adhered materials will be continuously heated by the inner wall of the tank, causing the adhered materials to burn and affect the final product.
[0004] In response to this, a stirring frame is added to some stirring devices, and a whole scraper is connected to the outer periphery of the stirring frame. When the rotating shaft rotates, the scraper can be driven to rotate and scrape the material adhering to the inner wall of the cooking tank. However, the scraper is prone to local deformation due to uneven force during the scraping process, resulting in failure to fit the inner wall of the tank, resulting in poor scraping effect. In addition, a whole scraper needs to be replaced as a whole after it is damaged, which is difficult to disassemble and assemble, and the replacement cost is also high. Utility Model Content
[0005] The utility model aims to provide a stirring device, which can improve the scraping effect of the scraper and reduce the cost of replacing the scraper after the scraper is damaged.
[0006] The utility model provides a stirring device, comprising: a tank body, a driving part, a stirring frame and a plurality of scrapers. The output end of the driving part is formed as a rotating shaft, at least part of the rotating shaft is arranged in the tank body, the stirring frame is fixedly connected to the rotating shaft in the tank body, and is arranged with a gap corresponding to the inner wall of the tank body, and the plurality of scrapers are arranged on a side surface of the stirring frame close to the inner wall of the tank body, and the plurality of scrapers abut against the inner wall of the tank body.
[0007] According to the technical solution of the utility model, compared with the existing one-piece scraper, the stirring device provided in the utility model is provided with a plurality of small scrapers on the side surface of the stirring frame close to the inner wall of the tank body, and the plurality of small scrapers are in contact with the inner wall of the tank body, so that the rotating shaft can drive the small scrapers to rotate and scrape the materials adhered to the inner wall of the tank body. In addition, the plurality of small scrapers are in contact with the inner wall of the tank body independently of each other to scrape the materials, so when some small scrapers are subjected to uneven force, it will not affect the fit between other scrapers and the inner wall of the tank body, and it is not easy to produce large deformation, and the scraping effect is better. In addition, the damaged or deformed small scrapers can be directly replaced without the need for overall replacement, and the replacement cost of the scrapers is lower.
[0008] As a preferred technical solution, the scraper is rotatably connected to the stirring frame, and the scraper is obliquely abutted against the inner wall of the tank body.
[0009] According to the preferred technical solution, the scraper and the stirring frame are rotatably connected, so that the scraper can rotate along with the trend when encountering resistance, thereby reducing the risk of the scraper being deformed by force. Furthermore, the scraper is inclinedly abutted against the inner wall of the tank body so that the surface of the scraper facing the material when the scraper rotates can be formed into an inclined guiding surface. Specifically, when the scraper rotates, the end of the scraper close to the stirring frame first contacts the material, and the material flows along the inclined guiding surface to the abutting end of the scraper and the inner wall of the tank body, thereby further reducing the resistance encountered by the abutting end of the scraper and the inner wall of the tank body, thereby reducing the risk of deformation and damage to the scraper.
[0010] As a preferred technical solution, the scraper includes: a fixed part, a rotating part, a U-shaped pin and a fixed pin. The fixed part is fixed to the surface of the stirring frame, the rotating part is connected to one end of the fixed part away from the stirring frame, the first connecting rod of the U-shaped pin is arranged at the connection between the fixed part and the rotating part in a manner of passing through the fixed part and the rotating part at the same time, and the fixed pin is arranged at the end of the first connecting rod.
[0011] According to the preferred technical solution, the cooperation between the U-shaped pin and the fixed pin enables the rotating part to rotate around the first connecting rod of the U-shaped pin, and the connection between the U-shaped pin and the fixed pin can be easily disassembled and assembled, which is convenient for disassembly and replacement of the rotating part of the scraper.

[0013] According to this preferred technical solution, the second connecting rod of the U-shaped pin is set on the side where the rotating part rotates away from the inner wall of the tank body, so the U-shaped pin can be directly used to limit the rotation angle of the scraper, thereby preventing the scraper from being flipped under force and ensuring the scraping effect of the scraper on the inner wall of the tank body.
[0014] As a preferred technical solution, a surface of the scraper on one side close to the inner wall of the tank body is inclined toward a surface on the opposite side, so that the scraper forms an edge with a gradually decreasing thickness.
[0015] According to this preferred technical solution, the contact area between the scraper and the material can be increased to form two progressive guiding slopes, and the scraper forms an edge with a gradually decreasing thickness, that is, the scraper has a gradually sharp edge, which can better scrape off the material adhered to the inner wall of the tank.

[0018] As a preferred technical solution, multiple side wall scrapers and multiple bottom wall scrapers are arranged in a manner where the edges of the scrapers are sequentially connected. When the stirring frame rotates, the outer peripheral surfaces formed by the rotation of the multiple scrapers match the inner wall of the tank body.
[0019] According to the preferred technical solution, the scrapers are arranged in a manner that their edges are connected in sequence, so when the stirring frame rotates, the outer peripheral surface of the scrapers can more comprehensively scrape off the materials adhered to the inner wall of the tank body.
[0020] As a preferred technical solution, the stirring device further comprises: a manhole opened on the top of the tank body, and a sight glass arranged on the top of the tank body and facing the multiple scrapers on the surface of the stirring frame.
[0021] According to the preferred technical solution, for damage inspection and replacement of multiple scrapers, the operator can first observe the multiple scrapers through the sight glass. If the scrapers are intact, there is no need to enter the tank body. If the scrapers need to be replaced, the operator enters the tank body through the manhole and can also quickly locate the damaged scraper for replacement based on the observation results of the sight glass.

DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] It should be noted that, in the description of the present invention, terms indicating positional relationships such as "upper", "lower", "outer", "inner", "top" and "bottom" are based on the directions or positional relationships shown in the accompanying drawings. This is only to facilitate technicians in this field to understand the present invention more vividly, and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.
[0033] Figure 1 Schematic diagram of the overall structure of the stirring device provided in this embodiment. Figure 1 As shown. A common stirring device comprises a tank body 1 and a driving part 2. The tank body 1 comprises at least one material containing chamber 10 for containing materials, and the driving part 2 comprises a driving mechanism 21 (such as a rotary motor) and a rotating shaft 22 driven to rotate by the driving mechanism 21. The rotating shaft 22 extends into the material containing chamber 10 of the tank body 1, and a stirring structure such as a stirring blade 23 may be formed on the surface of the part of the rotating shaft 22 extending into the tank body 1, so that the driving mechanism 21 drives the rotating shaft 22 to rotate, and the stirring blade 23 can be driven to stir the materials in the tank body 1.
[0034] like Figure 1 As shown, in some preferred embodiments, the tank body 1 can be formed by combining a heat transfer wall 11 and an outer plate 12 covering the outside of the heat transfer wall 11. The heat transfer wall 11 encloses a material accommodating chamber 10. The inner wall of the tank body 1 abutted by the scraper 4 is the heat transfer wall 11. A hollow jacket chamber 13 is formed between the outer plate 12 and the heat transfer wall 11. A steam heating port 121 is provided on the outer plate 12, so that high-temperature steam can be filled into the jacket chamber 13 through the steam heating port 121 to heat the material in the tank body 1 and achieve stirring and cooking of the material in the material accommodating chamber 10. In other preferred embodiments, a support leg 5 is fixed to the bottom of the tank body 1 to support the tank body 1 and maintain the stability of the tank body 1. Furthermore, the support leg 5 also has a height adjustment mechanism (not shown in the figure) to facilitate adjusting the height of the tank body 1 and maintain the balance of the tank body 1. Furthermore, a heat-insulating layer 14 is provided inside the outer package plate 12, which can keep the temperature conducted from the heat transfer wall 11 to the material containing cavity 10 constant, thereby improving the temperature control performance of the stirring mechanism during steaming and stirring.
[0035] In particular, the stirring device provided in this embodiment also has a stirring frame 3 and a plurality of scrapers 4 fixed to the surface of the stirring frame 3, the stirring frame 3 is fixedly connected to the rotating shaft 22 extending into the material containing chamber 10, and the stirring frame 3 and the inner wall of the tank body 1 are arranged with a corresponding gap, and the plurality of scrapers 4 are arranged on the side surface of the stirring frame 3 close to the inner wall of the tank body 1 in contact with the inner wall of the tank body 1, so that when the rotating shaft 22 rotates, it can simultaneously drive the stirring blades 23 to stir the material, and at the same time, it can also drive the small scraper 4 to rotate to scrape off the material adhered to the inner wall of the tank body 1.
[0036] In this embodiment, multiple small scrapers 4 are arranged independently of each other. When one or more small scrapers 4 are subjected to uneven force, it will not affect the fit between other scrapers 4 and the inner wall of the tank body 1, and it is not easy to produce large deformation. The scraping effect is better, and the damaged or deformed small scraper 4 can be directly replaced without replacing the entire scraper 4. The replacement cost of the scraper 4 is lower.
[0037] Among them, the cross section of the material containing chamber 10 of the tank body 1 can be a rotationally symmetrical figure, the rotating shaft 22 is set at the rotation center position of the material containing chamber 10, and the stirring frame 3 is formed on one or more longitudinal sections of the tank body 1 passing through the rotating shaft 22. One end of the stirring frame 3 is fixed to the rotating shaft 22, and the other end is spaced apart corresponding to the inner wall of the tank body 1, so that when the rotating shaft 22 rotates, the outer peripheral surface formed by the rotation of the stirring frame 3 is similar in shape to the inner wall of the tank body 1. On this basis, it is only necessary to set a plurality of scrapers 4 of uniform size on the surface corresponding to the outer peripheral surface of the stirring frame 3 when rotating, so that the scraper 4 can evenly scrape the material adhered to the inner wall of the tank body 1 during the rotation process, and the uniform model of the scraper 4 is also more conducive to reducing the replacement cost.
[0038] Among them, preferably, the stirring frame 3 corresponds to the side wall and the bottom wall of the inner wall of the tank body 1, and the multiple scrapers 4 also correspondingly include multiple side wall scrapers 41 and multiple bottom wall scrapers 42. The multiple side wall scrapers 41 are arranged on the surface of the stirring frame 3 corresponding to the inner side wall of the tank body 1, and the multiple bottom wall scrapers 42 are arranged on the surface of the stirring frame 3 corresponding to the bottom wall of the tank body 1, so that when the stirring frame 3 rotates, it can drive the scraper 4 to scrape off the material adhered to the side wall and the bottom wall of the tank body 1 at the same time.
[0039] Further preferably, a plurality of side wall scrapers 41 are sequentially arranged on the surface of the stirring frame 3 along the height direction of the tank body 1, and a plurality of bottom wall scrapers 42 are sequentially arranged on the surface of the stirring frame 3 along the radial direction of the bottom surface of the tank body 1, and the plurality of side wall scrapers 41 and the plurality of bottom wall scrapers 42 are directed toward the edge 43 of the inner wall of the tank body 1 (see Figure 2 and Figure 3 ) are connected in sequence, so that the edges 43 of multiple scrapers 4 can be sequentially combined to form a continuous scraping edge, and the continuous scraping edge can abut against the side wall and bottom wall of the tank body 1, so that the material adhered to the inner wall of the tank body 1 can be scraped more comprehensively.
[0040] Figure 2 FIG. 1 is a diagram showing the contact structure between the scraper of the stirring device provided in this embodiment and the inner wall of the tank body (i.e., the inner wall surface of the heat transfer wall 11 in the figure). Figure 1 and Figure 2 From the perspective of the scraper 4, the scraper 4 is rotatably connected to the outer peripheral surface of the stirring frame 3, so that the scraper 4 can rotate smoothly when encountering resistance, reducing the risk of deformation of the scraper 4 due to force. Furthermore, for the rotatable scraper 4, the scraper 4 can also be inclinedly abutted against the inner wall of the tank body 1 during use. When the scraper 4 rotates, the side surface facing the material is formed into an inclined guiding surface. Specifically, when the scraper 4 rotates, the end of the scraper 4 close to the stirring frame 3 first contacts the material, and the material flows along the inclined guiding surface to the abutment end of the scraper 4 and the inner wall of the tank body 1, thereby further reducing the resistance of the abutment end of the scraper 4 and reducing the risk of deformation and damage of the scraper 4.
[0041] Figure 3 Schematic diagram of the connection structure between the scraper and the stirring frame of the stirring device provided in this embodiment. Figure 2 and Figure 3 From the perspective of the scraper 4, the scraper 4 includes: a fixed portion 44, a rotating portion 45, a U-shaped pin 46 and a fixed pin 47. The fixed portion 44 is fixed to the surface of the stirring frame 3, the rotating portion 45 is connected to one end of the fixed portion 44 away from the stirring frame 3, the first connecting rod 461 of the U-shaped pin 46 is arranged at the connection between the fixed portion 44 and the rotating portion 45 in a manner of passing through the fixed portion 44 and the rotating portion 45 at the same time, and the fixed pin 47 is arranged at the end of the first connecting rod 461.
[0042] The fixed portion 44 and the rotating portion 45 can be passed through by the first connecting rod 461 side by side, or, in some preferred embodiments, as Figure 3 As shown, both sides of the fixed portion 44 protrude to form connecting ends 441, and one end of the rotating portion 45 close to the fixed portion 44 is arranged between the two connecting ends 441, and the first connecting rod 461 of the U-shaped pin 46 passes through the connecting end 441 of the fixed portion 44-the rotating portion 45-the connecting end 441 of the fixed portion 44 in sequence, and the end of the first connecting rod 461 that passes through is fixed by the fixing pin 47, so that the connecting end 441 of the fixed portion 44 can further limit the linear movement of the first connecting rod 461 of the rotating portion 45 along the U-shaped pin 46, thereby avoiding friction and damage caused by overlapping of the scraper 4.
[0043] Preferably, the second connecting rod 462 of the U-shaped pin 46 can be directly arranged on the outside of the connection between the fixed part 44 and the rotating part 45, and the second connecting rod 462 is on the side of the rotating part 45 that rotates away from the inner wall of the tank body 1, such as Figure 3 As shown, when the rotating part 45 rotates in the direction away from the inner wall of the tank body 1, the thickness of the connection between the rotating part 45 and the fixed part 44 on the side away from the inner wall of the tank body 1 increases (because the rotating part 45 and the fixed part 44 overlap obliquely). Since the distance between the first connecting rod 461 and the second connecting rod 462 of the U-shaped pin 46 is constant, the U-shaped pin 46 can be used to limit the rotation angle of the scraper 4 to prevent the scraper 4 from flipping under force, thereby ensuring the scraping effect of the scraper 4 on the inner wall of the tank body 1.
[0044] Further preferably, the surface of one side of the scraper 4 close to the inner wall of the tank body 1 is inclined toward the surface on the opposite side, so that the scraper 4 forms an edge 43 with a gradually decreasing thickness, so that when the scraper 4 rotates, the surface on the side facing the material forms two sections of progressive inclined guiding surfaces, which can increase the contact area between the scraper 4 and the material. The scraper 4 has a gradually sharp edge 43, which can better scrape off the material adhered to the inner wall of the tank body 1.
[0045] In other optional embodiments of the utility model, the stirring device further includes: a manhole 7 opened at the top of the tank body 1, and a sight glass 6 provided on the top of the tank body 1 and facing the multiple scrapers 4 on the surface of the stirring frame 3. For damage inspection and replacement of multiple scrapers 4, the operator can first observe the multiple scrapers 4 through the sight glass 6. If the scrapers 4 are intact, there is no need to enter the tank body 1. If the scrapers 4 need to be replaced, the operator enters the tank body 1 through the manhole 7, and can also quickly locate the damaged scrapers 4 for replacement based on the observation results of the sight glass 6. It can reduce the time for the operator to operate in the tank body 1 and save the labor cost of damage inspection and replacement of the scrapers 4.
[0046] Those skilled in the art will appreciate that, in the above-mentioned embodiments, many technical details are provided in order to enable readers to better understand the present application. However, even without these technical details and various changes and modifications based on the above-mentioned embodiments, the technical solutions claimed for protection by the claims of the present application can be basically realized. Therefore, in practical applications, various changes can be made to the above-mentioned embodiments in form and detail without departing from the spirit and scope of the present utility model.
