Technical Field
[0001] This utility model relates to the field of mixing tank technology, and in particular to a mixing tank that is easy to clean. Background Technology
[0002] As the food industry enters the era of large-scale industrialization, people are paying increasing attention to food nutrition and hygiene. The importance of food science and engineering in the food industry is becoming more and more prominent. As a key piece of equipment used for material mixing, homogenization and reaction in the food production process, the stirred tank plays a vital role in ensuring the efficiency of food processing and the stability of product quality. It can greatly optimize various processes in food engineering and help the food industry achieve high-quality development.
[0003] The existing patent (publication number: CN220759047U) discloses "This utility model discloses a mixing tank for easy cleaning in food engineering, relating to the field of mixing tank technology. It includes a chassis, with two support rods fixedly connected to the top of the chassis. A mixing drum is fixedly connected to the top of the two support rods. The beneficial effects of this utility model are: the scrapers at both ends of the rotating rod can scrape off food from the inner wall of the mixing drum, preventing food adsorbed on the inner wall from being missed during mixing; the driving component drives the rotating tube to rotate, and the water spray pipe also rotates simultaneously. This rotation allows water to not only flow into the mixing drum but also spray onto the inner wall of the mixing drum, achieving a flowing water rinsing effect. While the water spray pipe sprays onto the mixing drum, the rotation of the mixing rod drives the outer ring of the mixing rod to move up and down within the sliding groove, thereby driving the scrapers at both ends of the rotating rod to clean the food from the inner wall of the mixing drum, thus improving the cleaning effect of the mixing drum."
[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: When the mixing vessel is stirring, the food is stirred by the stirring rod and the rotating rod. The stirring method is relatively simple, which makes it difficult to ensure that the food is mixed evenly and easily affects the stirring quality of the food. Moreover, when cleaning the inside of the mixing vessel, the structure of the entire device becomes relatively complex, which increases the manufacturing and maintenance costs.
[0005] Therefore, those skilled in the art have provided a stirred tank that is easy to clean in order to solve the problems mentioned in the background art. Utility Model Content

The combination of these two methods can clean the inside of the mixing vessel in an all-round and thorough manner, effectively removing attached food, improving cleaning efficiency, and reducing the workload and difficulty of manual cleaning.
[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A fixing block is fixedly installed on one side of the lower end of the rotating shaft. A stirring shaft is slidably installed on the outside of the rotating shaft. A fixing groove is opened at the upper end of the inside of the stirring shaft. A connecting groove is opened at the lower end of the inside of the stirring shaft. A reciprocating lead screw is fixedly installed at the lower end of the inside of the mixing vessel body.
[0010] Furthermore, the motor is externally fixedly installed inside the upper part of the mixing vessel body, the upper end of the first bevel gear is rotatably installed inside the upper part of the mixing vessel body, and the lower end of the second bevel gear is rotatably installed inside the mixing vessel body at the end away from the first bevel gear.
[0011] Furthermore, the second bevel gear meshes with the third bevel gear, the third bevel gear meshes with the first bevel gear, one of the two water pipes is externally fixedly installed on the upper end of the mixing vessel body, the other of the two water pipes is externally fixedly installed inside the rotating shaft, and the input ends of the plurality of nozzles are respectively fixedly installed on the other output end of the two water pipes.
[0012] Furthermore, multiple scrapers are fixedly installed on the outside of the connecting shaft, and the multiple scrapers are arranged on opposite sides of each other on the inner wall of the mixing vessel body.

[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model proposes a mixing vessel that is easy to clean. When mixing food, the motor drives the third bevel gear to rotate, which in turn drives the first and second bevel gears to rotate synchronously, causing the scraper outside the connecting shaft to rotate. At the same time, the rotating shaft drives the mixing shaft to rotate through the fixed block, which in turn causes the mixing blades to rotate. The rotation direction of the mixing blades is opposite to that of the scraper. Moreover, the connecting groove at the lower end of the mixing shaft is threaded to the reciprocating screw.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figures 1-5 One embodiment provided by this utility model:
[0028] A cleaning-friendly mixing vessel includes a mixing vessel body 1. A cleaning and mixing mechanism 3 is provided inside the mixing vessel body 1. The cleaning and mixing mechanism 3 includes a motor 307. A third bevel gear 310 is fixedly installed at the output end of the motor 307. A connecting shaft 312 is rotatably installed at the upper end inside the mixing vessel body 1. A second bevel gear 309 is fixedly installed at the upper end of the connecting shaft 312. A rotating shaft 306 is rotatably sleeved inside the connecting shaft 312. A first bevel gear 308 is fixedly installed at the upper end of the rotating shaft 306. A rotating block 316 is rotatably installed at the upper end of the rotating shaft 306. Water pipes 305 are rotatably installed at both the upper and lower ends of the rotating block 316. Multiple nozzles 311 are fixedly installed at the lower end of the rotating shaft 306.
[0029] A fixing block 313 is fixedly installed on one side of the lower end of the rotating shaft 306. A stirring shaft 303 is slidably installed on the outside of the rotating shaft 306. A fixing groove 314 is opened at the upper end of the stirring shaft 303. A connecting groove 315 is opened at the lower end of the stirring shaft 303. A reciprocating screw 304 is fixedly installed at the lower end of the stirring vessel body 1.
[0030] The motor 307 is externally fixedly installed inside the upper part of the mixing tank body 1. The upper end of the first bevel gear 308 is rotatably installed inside the upper part of the mixing tank body 1. The lower end of the second bevel gear 309 is rotatably installed inside the mixing tank body 1 at the end away from the first bevel gear 308. The second bevel gear 309 is meshed with the third bevel gear 310. The third bevel gear 310 is meshed with the first bevel gear 308. One of the two water pipes 305 is externally fixedly installed on the upper part of the mixing tank body 1, and the other of the two water pipes 305 is externally fixedly installed inside the rotating shaft 306. The input ends of multiple nozzles 311 are respectively fixedly installed on the output ends of the other of the two water pipes 305. Multiple scrapers 301 are externally fixedly installed on the connecting shaft 312. The multiple scrapers 301 are arranged on opposite sides of the inner wall of the mixing tank body 1. Multiple stirring blades 302 are externally fixedly installed on the stirring shaft 303. The upper end of the reciprocating screw 304 is threadedly connected to the inside of the connecting groove 315. The fixing block 313 is externally slidably installed inside the fixing groove 314.
[0031] Specifically, when stirring food, starting the motor 307 drives the third bevel gear 310 to rotate inside the mixing vessel body 1. Since the third bevel gear 310 is meshed with both the first bevel gear 308 and the second bevel gear 309, the first and second bevel gears 308 and 309 rotate synchronously under the drive of the third bevel gear 310. The rotation of the second bevel gear 309 causes the connecting shaft 312 to rotate accordingly. Multiple scrapers 301 fixed to the outside of the connecting shaft 312 then move in a circular motion along the inner wall of the mixing vessel body 1, continuously scraping the inner wall and effectively preventing food from adhering to it. The rotation of the first bevel gear 308 drives the rotating shaft 306 to rotate synchronously inside the mixing vessel body 1. When the rotating shaft 306 rotates, the fixed block 313 also rotates. The outer side of the fixed block 313 is slidably connected to the fixing groove 314 inside the stirring shaft 303. When the fixed block 313 rotates, it drives the stirring shaft 303 to rotate, which in turn drives the multiple stirring blades 302 on its outside to rotate. The rotation direction of the stirring blades 302 is opposite to that of the scraper 301, so that the food is subjected to more complex and stronger forces during the stirring process, achieving efficient mixing. Moreover, the connecting groove 315 at the lower end of the stirring shaft 303 is threadedly connected to the reciprocating screw 304. When the stirring shaft 303 rotates, it will move up and down along the reciprocating screw 304. During the up and down movement of the stirring shaft 303, the fixing groove 314 inside slides along the rotating shaft 306 and the outer side of the fixed block 313, so that the stirring blades 302 can perform thorough and deep mixing of the food without dead angles, ensuring that the food is evenly mixed.
[0032] When it is necessary to clean the inside of the mixing tank body 1, simply turn on the water pipe 305. During the operation of the motor 307, the rotating shaft 306 drives the internal nozzles 311 to rotate synchronously. Water flows smoothly into the nozzles 311 through the water pipe 305. As the nozzles 311 rotate, they spray high-pressure water into every corner of the mixing tank body 1, thoroughly and completely rinsing and cleaning the inside of the mixing tank body 1. In addition, the scraper 301 scrapes along the circumference of the inner wall of the mixing tank body 1, and the stirring blades 302 move up and down as they rotate. The rotating nozzles 311 spray water to rinse, achieving all-round cleaning of the inside of the mixing tank, effectively removing food residue, reducing the workload and difficulty of manual cleaning, ensuring equipment hygiene, and the cleaning structure is relatively simple, reducing manufacturing and maintenance costs.
[0033] Reference Figures 1-2 A feed hopper 4 is fixedly installed at the upper end of the mixing tank body 1, a discharge port 6 is fixedly installed at the lower end of the mixing tank body 1, multiple support legs 2 are fixedly installed at the lower end of the mixing tank body 1, and a control panel 5 is fixedly installed at the front end of the mixing tank body 1.
[0034] Specifically, when feeding is required, the food enters the mixing tank body 1 through the feeding hopper 4. After mixing, the food is discharged from the discharge port 6, which facilitates the entry and exit of the food. The operator can control the equipment through the control panel 5, which is convenient to operate. The multiple support legs 2 at the lower end of the mixing tank body 1 will provide stable support and enhance the stability of the equipment.
[0035] Working Principle: During operation, the food to be stirred is fed into the mixing vessel body 1 through the feed hopper 4. Then, the motor 307 is started, and its output drives the third bevel gear 310 to rotate. Since the third bevel gear 310 meshes with the first bevel gear 308 and the second bevel gear 309, the first and second bevel gears 308 and 309 also rotate. The rotation of the second bevel gear 309 drives the connecting shaft 312 to rotate. Multiple scrapers 301 fixed to the outside of the connecting shaft 312 then move in a circular motion along the inner wall of the mixing vessel body 1, scraping and cleaning the inner wall to prevent food from adhering to it. Simultaneously, the rotation of the first bevel gear 308 drives the rotating shaft 306 to rotate inside the mixing vessel body 1. The rotation of the rotating shaft 306 synchronously... The fixed block 313 on its outside is driven to rotate. Since the fixed block 313 is slidably set in the fixed groove 314 inside the stirring shaft 303, when the fixed block 313 rotates, it will drive the stirring shaft 303 to drive the multiple stirring blades 302 on its outside to rotate, so that they can mix and stir the food inside the stirring vessel body 1. The rotation direction of the stirring blades 302 is opposite to the rotation direction of the scraper 301. Since the connecting groove 315 at the lower end of the stirring shaft 303 is threadedly connected to the reciprocating screw 304, when the stirring shaft 303 rotates, it will move up and down on the outside of the reciprocating screw 304. When the stirring shaft 303 moves up and down, the fixed groove 314 inside it will slide on the outside of the rotating shaft 306 and the fixed block 313, so that the stirring blades 302 can fully stir the food.
[0036] When cleaning the inside of the mixing tank body 1, the water pipe 305 is turned on, the motor 307 is turned on, and the rotating shaft 306 will drive the nozzle 311 inside to rotate synchronously. The water flow will enter the nozzle 311 through the water pipe 305. During the rotation of the nozzle 311, water flow is sprayed in all directions inside the mixing tank body 1. The rotation of the mixing blade 302 and the scraper 301 can improve the cleaning effect.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
