Multiple fans are uniformly fixedly connected to the top of the tank near its outer wall for cooling the internally stirred raw materials. Multiple heat dissipation holes are uniformly opened on the outer wall of the tank near the top to facilitate heat dissipation from the high internal temperature, thereby improving the cooling speed. A stirring mechanism is fixedly connected to the center of the top of the tank. The stirring mechanism includes a motor, and a rotating shaft is fixedly connected to the end face of the motor's drive shaft. A spiral blade is fixedly connected to the outer wall of the rotating shaft, and the rotating shaft is driven by the motor's drive shaft. This invention improves the cooling speed of the baijiu raw materials by uniformly and effectively stirring them, and the combined effect of the fan device to accelerate the airflow further enhances the cooling efficiency of the baijiu raw materials.

[0005] The aforementioned device improves cooling efficiency by stirring the raw materials for liquor and simultaneously increasing airflow through a blower. However, according to the instruction manual and accompanying drawings, the heat dissipation holes are located on the outer periphery of the tank without any protection. Dust, raw material particles, or condensate from the production environment may enter the tank through the heat dissipation holes, leading to contamination of the raw materials. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that the above-mentioned device improves cooling efficiency by stirring the raw materials of liquor and increasing the air flow rate with a blower. However, according to the specification and drawings, the heat dissipation holes are opened on the outer periphery of the tank and are not protected.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, dust is directly intercepted through a porous structure, preventing it from entering the tank. The staggered arrangement of heat dissipation holes one and two forms a tortuous airflow path, increasing the probability of dust impacting and adhering to the filter screen, thus enhancing the interception effect.

[0024] Reference Figures 1 to 4 In this embodiment of the present invention, a liquor raw material cooling device includes a tank body 1. A stirring mechanism 3 is provided at the top of the tank body 1. A feed pipe 4 is fixedly installed at one end of the tank body 1, and a discharge pipe 5 is fixedly installed at the bottom of the tank body 1. A heat dissipation hole 7 is evenly arranged around one end of the tank body 1. A protective shell 8 is welded and fixed at one end of the tank body 1 and at the end of the heat dissipation hole 7.

[0025] The above-mentioned scheme is adopted as follows: the stirring mechanism 3 and the tank 1 are prior art as cited in the prior art documents and are not described in detail in this application. The tank 1 has heat dissipation holes 7 evenly distributed on its outer circumference. The protective shell 8 is made of 304 stainless steel and is welded and fixed to the tank 1. The heat dissipation holes 9 are evenly distributed on the circumference of the protective shell 8 and are staggered with the heat dissipation holes 7 to form a labyrinth-like heat dissipation channel. The filter screen 11 is made of 316L stainless steel woven mesh and is embedded in the protective shell 8 and fixed to the protective shell 8 by countersunk bolts. The collection shell 10 is made of stainless steel. The cleaning plate 12 is made of nylon 66 and its width matches that of the filter screen 11. Two guide sliders (POM material) are installed on the back and slide along the T-slot of the guide rail on the inner wall of the protective shell 8.

[0026] Reference Figures 1 to 4The protective sleeve 8 has a cavity 13 inside, and a connecting rod 14 is slidably connected inside the cavity 13. The connecting rod 14 passes through the cavity 13 and is fixedly installed with the cleaning plate 12. A U-shaped rod 16 is provided at the top of the protective sleeve 8, and the U-shaped rod 16 passes through the cavity 13 and is fixedly installed with the connecting rod 14. A return spring 15 is fixedly installed inside the cavity 13, and the return spring 15 is sleeved on the outer periphery of the connecting rod 14.

[0027] The above scheme is adopted: the cavity 13 is opened in the inner wall of the protective sleeve 8, with a rectangular cross section and closed at both ends. The connecting rod 14 is made of stainless steel 304, with chrome plating on the rod body. The lower end is fastened to the screw hole on the back of the cleaning plate 12, and the upper end is machined with an M6 threaded section and welded to the U-shaped rod 16 to the fixing plate. The U-shaped rod 16 is made of stainless steel round steel cold-bent and locked to the connecting rod 14 by an M6 nut. The surface is polished. The return spring 15 is made of 60Si2Mn spring steel, with both ends tightly ground flat and the surface galvanized and passivated. The connecting rod 14 and the top through hole of the cavity 13 adopt a clearance fit and are embedded with a polytetrafluoroethylene guide sleeve to ensure smooth reciprocating motion.

[0028] Reference Figures 1 to 4 The top of the collection shell 10 is provided with a collection groove 17, and the two ends of the collection shell 10 are symmetrically fixed with mounting blocks 18, and the bottom end of the mounting block 18 is threadedly connected with a threaded rod 19, which passes through the mounting block 18 and is threadedly fixed to the protective sleeve 8.

[0029] The above solution is adopted: the collection trough 17 is opened on the top surface of the collection shell 10; the mounting block 18 is made of H59 brass, with an M8 threaded blind hole machined in the center of its bottom surface, and is fixed to the collection shell 10 by countersunk screws; the threaded rod 19 is made of 45# steel with heat treatment, and its head is an internal hexagonal cylindrical end, which mates with the threaded hole on the bottom surface of the protective sleeve 8; the bottom surface of the protective sleeve 8 has two rows of pre-set threaded holes; the threaded rod 19 is pre-tightened through the mounting block 18 to ensure that it does not loosen under vibration.

[0030] Reference Figures 1 to 4 A fan 2 is fixedly installed at the top of the tank body 1, and the fan 2 is symmetrically fixedly installed at the top of the tank body 1. A support rod 6 is fixedly installed at the bottom of the tank body 1, and the support rod 6 is evenly fixedly installed around the bottom of the tank body 1.

[0031] The above solution is adopted: Fan 2 is the prior art mentioned in the reference document and is not described in detail in this application.

[0032] Reference Figures 1 to 4 The bottom of the filter screen 11, which is located directly below the cleaning plate 12, is sloped.

[0033] The above solution is adopted: the bottom slope of the filter screen plate 11 is designed with an inclination angle to form a flow guiding angle with the horizontal plane, and the surface is coated with Teflon coating. The friction coefficient of Teflon coating is one of the lowest among solid materials, which can reduce the adhesion of dust on the surface of the filter screen plate 11 and prevent clogging of the filter screen plate 11.

[0034] The working principle of this utility model is as follows: The filter plate 11 is fixed inside the protective shell 8, located outside the heat dissipation hole 7. When air passes through the heat dissipation hole 9, the internal space of the protective shell 8, and then through the filter plate 11 into the heat dissipation hole 7, dust particles are intercepted by the pore structure of the filter plate 11 and cannot enter the tank 1 with the airflow. The heat dissipation hole 7 and the heat dissipation hole 9 are staggered, and the filter plate 11 is set in the middle, forming a tortuous airflow path. This design extends the path of dust into the tank 1, increases the probability of dust impacting and adhering to the filter plate 11, and further reduces dust passage. The bottom end of the filter plate 11 is designed with a slope. The intercepted dust slides down the slope under the action of gravity, avoiding accumulation on the filter surface and maintaining the ventilation of the filter. Efficiency and interception effect are achieved. At the same time, the staff presses the U-shaped rod 16, which drives the connecting rod 14 to slide in the cavity 13, thereby driving the cleaning plate 12 to slide along the surface of the filter screen plate 11. The reset spring 15 is sleeved on the outer periphery of the connecting rod 14. After pressing, the cleaning plate 12 is reset, realizing the reciprocating cleaning action. The cleaning plate 12 slides close to the surface of the filter screen plate 11, scraping off the dust attached to the filter screen surface. Since the bottom end of the filter screen plate 11 is inclined, the scraped dust slides down the inclined surface into the collection groove 17 of the collection shell 10. The collection shell 10 is detachably connected to the protective shell 8 through the mounting block 18 and the threaded rod 19. The collection shell 10 can be emptied by periodically rotating the threaded rod 19 to remove the collection shell 10, thereby emptying the dust in the collection groove 17 and realizing the effective collection and treatment of dust.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
