Description
Technical Field
[0001] This utility model relates to the field of food processing technology, specifically to a mixing tank and a mixing device. Background Technology
[0002] Currently in the food processing industry, traditional mixing bowls or tanks are mostly cylindrical in structure. When using an electric mixer, there is a problem that the bottom corners are difficult to mix evenly. With the development of technology, more and more mixing containers with curved bottoms have emerged (such as curved bottom mixing bowls, curved bottom mixing tanks, curved bottom mixing basins, and curved bottom mixing pots), which have solved the above problems.
[0003] However, the current stirring device still has some problems, such as:
[0004] First, existing stirring devices with electric stirring functions are generally fixed above the stirring container, such as on the lid of the stirring container, or supported by a separate support structure. For example, in a stirring device for seasoning production with patent publication number CN218485751U, the stirrer is fixed on a lid that can be flipped open; in a Tibetan medicine hot pot base formula, processing equipment and processing technology with patent publication number CN117598464A, the stirrer is supported by a separate bracket; and in a flavor and fragrance rapid mixing device for easy material collection with patent publication number CN213854074U, the stirrer is fixed on the lid, the material is discharged from the bottom of the stirring container, and the lid does not need to be opened. These designs all currently have the problem that the stirring shaft of the stirrer is in a cantilever state. When the stirring resistance is high, the rotation of the cantilevered stirring shaft is unstable, which affects the life of the stirrer's drive motor.
[0005] Secondly, the height of the agitator blades is not adjustable. However, considering the mixing efficiency and uniformity, the mixing tank or mixing vessel has a certain depth. Since the height of the agitator blades is fixed, it means that some raw materials may be difficult to mix evenly or the mixing effect may be poor. Utility Model Content
[0006] The present invention aims to provide a mixing tank to solve the problem of unstable rotation due to high mixing resistance caused by the cantilever rotation of the mixing shaft of current mixers, which in turn affects the life of the mixing motor.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A mixing tank includes a tank body, a guide column fixed inside the tank body, and a stirrer inserted inside the tank body. The cantilever end of the stirrer shaft is rotatably connected to the guide column. The stirrer shaft is an adjustable length shaft. After the length of the stirrer shaft is adjusted, the height position of the stirring blades on the stirrer shaft is adjusted accordingly.
[0009] The principle and advantages of this solution are as follows: When this solution is adopted, by setting up a mixing tank with guide columns, the mixing shaft of the agitator in the mixing tank no longer has a cantilever end during mixing. Both ends of the mixing shaft are restricted, so even if the mixing resistance is large, the rotational stability of the mixing shaft can still be guaranteed, thereby reducing the impact on the life of the agitator drive motor.
[0010] In addition, the stirring shaft of this solution can be length adjusted, thereby adjusting the position of the stirring blades inside the tank, which helps to achieve rapid and uniform mixing of raw materials according to different mixing scenarios.
[0011] Preferably, as an improvement, the bottom of the barrel is provided with a discharge port, which is connected to a discharge pipe. A discharge valve is installed on the discharge pipe so that the mixed material can be discharged directly by opening the discharge valve after the mixing is completed.
[0012] Preferably, as an improvement, it also includes a weighing device for weighing the raw materials discharged from the discharge valve, so as to facilitate weighing the finished product discharged after the agitator has finished mixing.
[0013] Preferably, as an improvement, it also includes a support for supporting the barrel, with casters installed at the bottom of the support to facilitate the movement of the stirring device.
[0014] This utility model also provides a stirring device, including the stirring tank, and a container cover that is closed on the top of the stirring tank, with the drive motor of the stirrer fixed on the container cover.
[0015] Preferably, as an improvement, the bottom of the barrel is an arc-shaped curved surface, and the stirring blades include arc-shaped blades. The arc-shaped blades are inclined relative to the arc-shaped bottom surface of the barrel, and the distance between the arc-shaped blades and the arc-shaped bottom surface is different at different radial positions of the stirring shaft, so that the arc-shaped blades can stir more effortlessly.
[0016] Preferably, as an improvement, the stirring blades include an upper stirring blade and a lower stirring blade. The upper stirring blade is in the shape of an inclined plate, and the lower stirring blade is the arc-shaped blade. The upper and lower stirring blades make the stirring faster and more even.
[0017] Preferably, as an improvement, the stirring shaft includes a first section and a second section. The first section is fixedly connected to the output end of the stirrer's drive motor, and the stirring blades are mounted on the second section. The first section and the second section are sleeved together, and the second section can move axially relative to the first section. It also includes a locking member for locking the relative position of the first section and the second section.
[0018] Beneficial effects: When it is necessary to adjust the height of the stirring blades according to different stirring tasks, the locking parts can be released from the first and second sections first. After the relative positions of the first and second sections are adjusted, the length of the stirring shaft can be adjusted, which means that the height of the stirring blades in the container can be changed to adapt to the stirring requirements of different heights.
[0019] Preferably, as an improvement, one of the first and second segments has a sleeve segment and the other has a shaft segment. The shaft segment is sleeved with the sleeve, and the locking element is a locking pin. The locking pin is threaded onto the sleeve and inserted into the sleeve to abut against the shaft segment. This solution achieves the length adjustment of the stirring shaft with a simple structure.
[0020] Preferably, as an improvement, the shaft segment is provided with at least one abutting surface, and the locking pin is used to abut against the abutting surface so that the locking pin has a sufficiently large abutting force on the shaft segment, ensuring that the length of the stirring shaft will not easily change during use.
[0021] Preferably, as an improvement, the first and second sections are connected by threads, and the locking element is a lock nut. The lock nut is threaded onto the stirring shaft and is used to lock the threaded connection position of the first and second sections. This solution provides another simple structure with an adjustable stirring shaft length.
[0022] Preferably, as an improvement, the container lid is provided with at least two feeding ports, and a sliding door or a feeding pipe is installed on the feeding port. The feeding pipe is used to connect with the feeding pump to facilitate the addition of raw materials to be mixed into the mixing tank in different ways. With the sliding door method, the feeding port can be set to be larger. When it is necessary to add materials, the sliding door is slid to expose the feeding port, which is convenient for direct addition into the mixing tank. With the feeding pipe method, it is convenient to add materials by direct pumping through the feeding pump. Attached Figure Description

[0035] The following detailed description illustrates the specific implementation method:
[0036] The reference numerals in the accompanying drawings include: barrel body 10, discharge port 101, guide column 102, bracket 20, moving wheel 201, discharge valve 30, weighing device 40, container lid 50, feeding port 501, sliding door 60, feeding pipe 70, stirring shaft 1, first section 11, second section 12, abutment surface 121, groove 122, locking element 13, stirring blade 2, drive motor 3, upper stirring blade 21, and lower stirring blade 22.
[0037] Example 1
[0038] Combination Figure 1 and Figure 2 A mixing tank includes a tank body 10, which is shaped like a pot or basin. The bottom of the tank body 10 has an arc-shaped bottom surface. A guide post 102 is fixed at the center of the bottom of the tank body 10. An agitator is inserted into the tank body 10 from top to bottom. The guide post 102 is fitted with the cantilever end of the agitator's stirring shaft 1 and can rotate relative to it. Specifically, the guide post 102 has a cylindrical outer circumference, and the cantilever end of the stirring shaft 1 is machined with a groove 122. The groove 122 fits into the guide post 102, and the depth of the groove 122 is greater than the length of the guide post 102 inserted into the groove 122. The fixed installation of the guide post 102 inside the tank body 10 ensures that the stirring shaft 1 no longer has a cantilever end when the agitator is stirring inside the mixing tank. Both ends of the stirring shaft 1 are restricted, so even if the stirring resistance is large, the rotational stability of the stirring shaft 1 can still be guaranteed, thereby reducing the impact on the life of the agitator drive motor.
[0039] The bottom of the barrel 10 has a discharge port 101, which is connected to a discharge pipe. A discharge valve 30 is installed on the discharge pipe. The barrel 10 also includes a weighing device 40 for weighing the raw materials discharged by the discharge valve 30, so that the material can be discharged directly from the bottom of the barrel 10 without disassembling the agitator.
[0040] It also includes a bracket 20 for supporting the barrel 10, with casters 201 mounted on the bottom of the bracket 20 to facilitate the transfer of the mixing barrel, and the casters 201 are equipped with brakes.
[0041] Example 2
[0042] Combination Figures 3 to 12 This embodiment provides a stirring device, including the stirring tank of Embodiment 1, and also includes a container cover 50 and a stirrer. The container cover 50 covers the open position of the tank body 10 of the stirring tank. The drive motor 3 of the stirrer is fixedly installed on the top of the container cover 50. The drive motor 3 is used to drive the stirring shaft 1 to rotate. If the drive motor 3 is a drive motor, the stirring shaft 1 passes through the container cover 50 and extends into the stirring tank.
[0043] The container lid 50 is an arc-shaped cover, and a feeding port 501 is opened on the container lid 50. A sliding door 60 is installed on the feeding port 501. Figure 3 and Figure 4 In this design, the feeding port 501 is a large opening on the side of the curved container lid 50. A curved sliding door 60 is installed on this large opening. The sliding door 60 is slidably connected to the container lid 50 and rotates around the center of the container lid 50 during sliding. This fully exposes the feeding port 501 after the sliding door 60 slides, facilitating feeding. Furthermore, the sliding door 60, combined with the curved shape of the container lid 50, allows for a larger feeding port 501, further simplifying the feeding process. Figure 5In the middle, a feeding pipe 70 is installed on the feeding port 501. The feeding pipe 70 can be connected to a feeding pump to facilitate the addition of raw materials into the mixing tank by pumping, thus facilitating automated feeding.
[0044] Combination Figures 6 to 12 The agitator includes a drive motor 3, a stirring shaft 1, and stirring blades 2 mounted on the stirring shaft 1. The length of the stirring shaft 1 can be adjusted, and the drive motor 3 is used to drive the stirring shaft 1 to rotate.
[0045] Specifically, the stirring shaft 1 includes a first section 11 and a second section 12. The first section 11 is used to be fixedly connected to the output end of the drive motor 3, and the drive motor 3 is fixedly installed on the container cover 50.
[0046] The stirring blade 2 is fixed on the second section 12 away from the drive motor 3. The first section 11 is sleeved with the second section 12, and the second section 12 can move axially relative to the first section 11. It also includes a locking member 13 for locking the relative position of the first section 11 and the second section 12.
[0047] Combination Figures 6 to 9 In one embodiment, the adjustable length of the stirring shaft 1 is specifically achieved as follows: the first section 11 facing the second section 12 is machined into a sleeve, the top of the second section 12 is machined into a shaft section, the shaft section is sleeved with the sleeve, and a locking member 13, which is a locking pin, is threaded onto the sleeve. The locking pin is inserted into the sleeve and abuts against the shaft section of the second section 12. To improve the locking force of the locking pin on the shaft section, at least one abutment surface 121 is provided on the shaft section. The shaft section can be... Figure 7 The cylindrical shaft shown has an axial abutment groove, which can also be... Figure 8 The shaft segment is a polygonal structure (a regular hexagonal structure in the figure), and the sleeve and the polygonal cross section of the shaft segment are fitted together. When adjusting the length of the stirring shaft 1, the locking pin is turned to release the locking pin from the second segment 12. Then, the second segment 12 is controlled to slide axially relative to the first segment 11, thereby adjusting the overall length of the stirring shaft 1. After the length adjustment is completed, the locking pin is turned again to make the locking pin press against the inner wall of the sleeve of the second segment 12 and the first segment 11, thereby ensuring that the length of the stirring shaft 1 will not change easily.
[0048] Combination Figure 10 and Figure 11In another embodiment, the length of the stirring shaft 1 is adjustable as follows: the first section 11 and the second section 12 are connected by threads. The sleeve of the first section 11 is provided with internal threads, and the shaft section of the second section 12 is provided with external threads. The locking member 13 is a locking nut, which is threaded onto the external threads. After the relative positions of the first section 11 and the second section 12 are adjusted, the length of the first section 11 and the second section 12 is locked by the locking nut pressing against the bottom end face of the first section 11. When adjusting the length, the locking nut is first screwed away from the first section 11, and then the second section 12 is screwed to change the axial position of the second section 12 relative to the first section 11. After the adjustment is completed, the locking nut is screwed again until it abuts against the bottom end face of the first section 11, thereby completing the locking of the length of the stirring shaft 1.
[0049] The stirring blade 2 includes an upper stirring blade 21 and a lower stirring blade 22 located at different heights. The distance between the upper stirring blade 21 and the inner wall of the tank 10 is greater than the distance between the lower stirring blade 22 and the inner wall of the tank 10. In a specific embodiment, the distance between the lower stirring blade 22 and the inner wall of the tank 10 can be set to be no less than 1 mm. The distance between the upper stirring blade 21 and the inner wall of the tank 10 is no less than 5 mm.
[0050] There are multiple lower stirring blades 22, which are evenly distributed around the stirring shaft 1. Each lower stirring blade 22 is arc-shaped, and the arc shape of the lower stirring blade 22 makes the distance between the lower stirring blade 22 and the inner wall of the barrel 10 gradually change, reducing the difficulty of stirring when the lower stirring blade 22 is in motion.
[0051] There are multiple upper stirring blades 21, and these blades are evenly distributed around the stirring shaft 1. The upper stirring blades 21 are inclined plates.
[0052] This embodiment uses an adjustable-length stirring shaft 1 to adapt to the stirring requirements of different stirring tasks, and the setting of upper stirring blades 21 and lower stirring blades 22 makes the stirring efficiency high and the stirring more uniform.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
