Description

Technical Field

[0001] This utility model belongs to the field of defoamer production technology for soy products, and specifically relates to a stirring device. Background Technology

[0002] Soy product defoamer is a food additive specifically used in the processing of soy products to inhibit or eliminate foam generated during production. In the processing of soy products (such as tofu, soy milk, soy milk, etc.), due to the high protein content, a large amount of foam is easily generated during heating and stirring. This foam not only affects production efficiency but may also cause product quality problems. Currently, in order to effectively control foam, special stirring devices are required.

[0003] Existing mixing devices generally use motors as the driving source to drive one or more mixing racks to rotate, and combine up and down movement or position adjustment to enhance the mixing effect. Although such devices can achieve multi-dimensional mixing of defoamer raw materials to a certain extent, there are still shortcomings in actual operation. Raw material sedimentation is prone to occur at the bottom of the mixing tank and inside the feed pipe, making it difficult for this part of the raw material to fully participate in the reaction process, thus affecting the uniformity and quality stability of the final product. Utility Model Content

[0004] In view of this, the present invention provides a stirring device that can effectively scrape off and stir the raw materials that are easy to settle at the bottom and in the feed pipe through the synergistic effect of centrifugal force and multi-dimensional motion. This solves the problem of insufficient participation caused by the sedimentation of raw materials at the bottom and in the feed pipe in traditional stirring devices, and significantly improves the uniformity and quality stability of defoamer products.

[0005] To address the aforementioned technical problems, this utility model provides a mixing device, including a mixing tank and a mixing mechanism disposed therein. The mixing mechanism also includes a bottom scraping structure, which comprises several rotating rods rotatably connected to the mixing mechanism. Each rotating rod has a mixing scraper at its lower end, and the lower ends of the mixing scrapers are in contact with the bottom wall of the mixing tank. The lower end of the mixing mechanism is also provided with a scraping component for scraping the inner arc surface of the discharge pipe of the mixing tank. This effectively scrapes and agitates the easily sedimented raw materials at the bottom and in the discharge pipe, avoiding uneven mixing caused by dead corner accumulation, and enhancing the dispersion and mixing effect of the raw materials at the bottom. Through the synergistic effect of centrifugal force and multi-dimensional motion, it ensures that the raw materials are mixed in all directions without dead corners within the tank, solving the problem of insufficient participation caused by the sedimentation of raw materials at the bottom and in the discharge pipe in traditional mixing devices, and significantly improving the uniformity and quality stability of the defoamer product.

[0006] The scraping component includes several rectangular scrapers evenly arranged at the lower end of the mixing mechanism, which scrape the inner arc surface of the feeding pipe to prevent the raw materials from depositing, adhering and clumping inside the feeding pipe.

[0007] It also includes a transmission assembly, which includes an annular plate located at the upper end of the inner cavity of the mixing tank. A rotating ring is rotatably connected to the lower end of the inner cavity of the annular plate. Each rotating rod is rotatably connected to a corresponding rotating hole on the rotating ring, which serves to provide safety protection and guide rotation for the internal mechanism.

[0008] The transmission assembly also includes gears respectively set on the upper end of the rotating rod, and the inner arc surface of the annular plate is provided with an internal toothed ring, which meshes with the gear to achieve the purpose of rapid transmission.

[0009] The stirring mechanism includes a rotating rod rotatably connected to the upper end of the inner cavity of the stirring tank. The lower end of the rotating rod is equipped with a stirring frame. Rotating rods are rotatably connected to the four corners of the stirring frame. The rotating rod is equipped with evenly distributed rectangular scrapers on the inner arc surface of the feed pipe of the stirring tank. A motor is installed at the upper end of the stirring tank. The output shaft of the motor is fixedly connected to the rotating rod, which achieves the function of rapid stirring.

[0010] The mixing mechanism also includes mixing plates that are evenly distributed on the outer side of the mixing frame, which further increases the mixing range and mixing effect.

[0011] The mixing scraper is a cross-shaped mixing scraper, which further enhances the dispersion and mixing effect of the raw materials at the bottom.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. After adding an appropriate amount of soy product defoamer raw material to the mixing tank, start the motor. The motor output shaft rotates, driving the rotating rod, mixing frame, and mixing plate to rotate synchronously, thereby performing the main mixing of the raw material in the tank. At the same time, the rotating rod, gear, and ring plate distributed at the four corners of the mixing frame rotate synchronously with the rotating rod. Through the transmission component, the rotating rod both revolves with the mixing frame and rotates on its own axis. The cross-shaped mixing scraper at its lower end continuously rotates against the bottom wall of the mixing tank, effectively scraping and stirring the raw material that is easy to settle at the bottom and in the feed pipe, avoiding uneven mixing caused by dead corner accumulation. The multi-directional contact design of the cross-shaped mixing scraper further enhances the dispersion and mixing effect of the raw material at the bottom. The linkage transmission structure between the rotating rod and the mixing frame, through the synergistic effect of centrifugal force and multi-dimensional motion, ensures that the raw material is mixed in all directions without dead corners in the tank, solving the problem of insufficient participation caused by the sedimentation of raw material at the bottom and in the feed pipe in traditional mixing devices, and significantly improving the uniformity and quality stability of the defoamer product.

[0014] 2. The internal toothed ring is fixed. While the gear rotates in a ring, it is driven by the meshing of the internal toothed ring, so that the rotating rod both revolves with the stirring frame and rotates on its own axis.

[0015] 3. The rectangular scraper extending from the lower end of the rotating rod to the feed pipe of the mixing tank rotates synchronously to scrape the inner arc surface of the feed pipe, preventing the raw materials from depositing, adhering and clumping inside the feed pipe.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a stirring device, such as... Figure 1-4 The diagram shows a mixing tank 100 and a mixing mechanism disposed therein. The mixing mechanism includes a rotating rod 400 rotatably connected to the upper end of the inner cavity of the mixing tank 100. A mixing frame 401 is provided at the lower end of the rotating rod 400. Rotating rods 200 are rotatably connected to the four corners of the mixing frame 401. Rectangular scrapers 202 are evenly distributed on the inner arc surface of the discharge pipe of the mixing tank 100 located on the rotating rod 400. A motor 403 is provided at the upper end of the mixing tank 100. The output shaft of the motor 403 is fixedly connected to the rotating rod 400. The mixing mechanism is also provided with a bottom scraping structure, which includes several rotating rods 200 rotatably connected to the mixing mechanism. A mixing scraper 201 is provided at the lower end of each rotating rod 200. The lower end of each mixing scraper 201 contacts the bottom wall surface of the mixing tank 100. The lower end of the mixing mechanism is also provided with a scraping component for scraping material on the inner arc surface of the discharge pipe of the mixing tank 100. The scraping component includes several rectangular scrapers 202 evenly distributed at the lower end of the mixing mechanism.

[0023] First, add an appropriate amount of soy product defoaming agent raw material to the mixing tank 100. Then, start the motor 403. The output shaft of the motor 403 rotates, driving the rotating rod 400, the mixing frame 401, and the mixing plate 402 to rotate synchronously, thereby performing the main mixing of the raw material in the tank. At the same time, the rotating rods 200 distributed at the four corners of the mixing frame 401 and the annular plate 300 rotate synchronously with the rotating rods 400. Then, the rotating rods 200 are driven to both revolve around and rotate on their own axis with the mixing frame 401. The cross-shaped mixing scraper 201 at its lower end continuously rotates in contact with the bottom wall of the mixing tank 100, effectively scraping and stirring the raw material that is easy to settle at the bottom and in the feed pipe, avoiding the mixing caused by dead corner accumulation. Meanwhile, the rectangular scraper 202, which extends from the lower end of the rotating rod 400 to the discharge pipe of the mixing tank, rotates synchronously to scrape the inner arc surface of the discharge pipe, preventing the raw materials from depositing, adhering, and clumping inside the discharge pipe. The multi-directional contact design of the cross-shaped mixing scraper 201 further enhances the dispersion and mixing effect of the raw materials at the bottom. The linkage transmission structure between the rotating rod 200 and the mixing frame 401 ensures that the raw materials are mixed in all directions without dead angles in the tank through the synergistic effect of centrifugal force and multi-dimensional motion. This solves the problem of insufficient participation caused by the sedimentation of raw materials at the bottom and in the discharge pipe in traditional mixing devices, and significantly improves the uniformity and quality stability of the defoamer product.

[0024] like Figure 2-4 As shown, it also includes a transmission assembly, which includes an annular plate 300 disposed at the upper end of the inner cavity of the mixing tank 100. A rotating ring 301 is rotatably connected to the lower end of the inner cavity of the annular plate 300. Each rotating rod 200 is rotatably connected to a corresponding rotating hole on the rotating ring 301. The transmission assembly also includes gears 302 disposed at the upper end of the rotating rods 200. An internal toothed ring 303 is provided on the inner arc surface of the annular plate 300, and the toothed ring 303 is meshed with the gear 302.

[0025] When the stirring rack 401 rotates, the rotating rods 200 distributed at its four corners, the gears 302 on them, and the annular plate 300 will rotate synchronously with the rotating rods 400. Since the internal toothed ring 303 is fixed, the gears 302 are driven by the meshing of the internal toothed ring 303 while rotating in annularly, so that the rotating rods 200 both revolve around the stirring rack 401 and rotate on their own axis.

[0026] like Figure 2-3 As shown, the stirring mechanism also includes stirring plates 402 that are evenly arranged on the outer side of the stirring frame 401, further increasing the stirring range and stirring effect.

[0027] like Figure 2-3 As shown, the stirring scraper 201 is a cross-shaped stirring scraper. The multi-directional contact design of the cross-shaped stirring scraper 201 further enhances the dispersion and mixing effect of the raw materials at the bottom.

[0028] The working principle of the stirring device provided by this utility model is as follows: First, an appropriate amount of defoaming agent for soybean products is added to the stirring tank 100. Then, the motor 403 is started. The output shaft of the motor 403 rotates, driving the rotating rod 400, the stirring frame 401, and the stirring plate 402 to rotate synchronously, thereby stirring the main ingredients in the tank. At the same time, the rotating rods 200, gears 302, and annular plates 300 distributed at the four corners of the stirring frame 401 rotate synchronously with the rotating rods 400. Since the internal toothed ring 303 is fixed, the gears 302 rotate in annular motion and are driven by the meshing of the internal toothed ring 303, causing the rotating rods 200 to both revolve around and rotate on their own axis with the stirring frame 401. The cross-shaped stirring scraper 201 at its lower end continuously rotates in contact with the bottom wall of the stirring tank 100. The system effectively scrapes and agitates easily settled raw materials at the bottom and in the discharge pipe, preventing uneven mixing caused by accumulation in dead corners. Simultaneously, the rectangular scraper 202, extending from the lower end of the rotating rod 400 to the discharge pipe of the mixing tank, rotates synchronously to scrape the inner arc surface of the discharge pipe, preventing raw materials from depositing, adhering, and clumping. The multi-directional contact design of the cross-shaped stirring scraper 201 further enhances the dispersion and mixing effect of the raw materials at the bottom. The linkage transmission structure between the rotating rod 200 and the stirring frame 401 ensures that the raw materials are mixed in all directions without dead corners in the tank through the synergistic effect of centrifugal force and multi-dimensional motion. This solves the problem of insufficient participation caused by the sedimentation of raw materials at the bottom and in the discharge pipe in traditional stirring devices, significantly improving the uniformity and quality stability of the defoamer product.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
