Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cooling devices, and in particular to a cooling device for grain and oil processing. Background Technology
[0002] Grains and oils are a general term for agricultural products such as cereals, beans, and oil crops, as well as their processed products. Grains mainly include raw grains such as wheat, rice, corn, and soybeans, as well as processed products such as rice, flour, noodles, and bean products. They are important sources of nutrients such as carbohydrates and proteins in the human diet, providing the body with basic energy.
[0003] The primary purpose of cooling during grain and oil processing is to ensure product quality and safety. High temperatures can easily lead to oil oxidation and rancidity, grain spoilage, or loss of nutrients in feed. They can also cause clumping, mold growth, or spontaneous combustion. Existing cooling devices typically use a motor's output shaft to drive a rotating shaft and auger blades, causing the raw materials inside the cylinder to continuously tumble and prevent heat from accumulating at the bottom. A vacuum pump then directs the hot air from the cylinder into a water tank, thus achieving heat dissipation. However, cooling by tumbling the raw materials using auger blades is inefficient, and the difference in tumbling between the edges and the center of the tank affects the overall cooling effect. Utility Model Content
[0004] The purpose of this invention is to provide a cooling device for grain and oil processing to solve the problems mentioned in the background art.
[0005] The technical solution adopted in this utility model is:
[0006] A cooling device for grain and oil processing includes a cooling box with an inlet at the top and an outlet on one side. A transmission assembly is located on one side of the cooling box, including transmission rods. Two transmission rods are located inside the cooling box. Each transmission rod has multiple first mounting holes on its surface. Multiple connecting blocks are attached to the surface of each transmission rod. Each connecting block has two second mounting holes on its surface. Bolts are threaded into the second and first mounting holes. A connecting rod is fixedly connected to one side of each connecting block, and a stirring block is fixedly connected to one side of each connecting rod. The stirring block has through holes on its surface.
[0007] In some embodiments, a second gear is fixedly connected to one side of the transmission rod, a first gear is meshed with the surface of the second gear, and one end of the first gear is fixedly connected to the output end of the motor.
[0008] In some embodiments, a water tank is fixedly connected to one end of the cooling box, an exhaust fan is fixedly connected to the top of the water tank, a connecting pipe is fixedly connected to one end of the exhaust fan, the exhaust fan's transmission port is connected to the interior of the water tank, a water supply pipe is fixedly connected to the top of the water tank, a spray head is fixedly connected to the bottom of the water supply pipe, a filter screen is provided at the bottom of the spray head, and a drain outlet is provided at one end of the water tank.
[0009] In some embodiments, the angle of the stirring block is inclined relative to the axial direction of the connecting rod, and the inclination angle ranges from 15° to 45°.
[0010] In some embodiments, the first mounting holes are arranged linearly at equal intervals along the surface of the transmission rod, and the spacing between two adjacent first mounting holes is adapted to the mounting width of the connecting block.
[0011] In some embodiments, the diameter of the first gear is larger than the diameter of the second gear.
[0012] In some embodiments, heat-conducting plates are fixedly connected to both ends of the cooling box, and reinforcing ribs are fixedly connected to the surface of the heat-conducting plates.
[0013] In some embodiments, the water tank has an outlet on its front side, and both the outlet and the middle of the water supply pipe are equipped with a stop valve.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] (i) To improve cooling efficiency, different sizes of stirring blocks can be replaced to adapt to processing needs. Operators can quickly remove the old stirring blocks by loosening the bolts and install the new stirring blocks by aligning the positions of the first and second mounting holes. For large particles such as soybeans, stirring blocks with larger through holes can be selected, while for small particles such as sesame seeds, stirring blocks with fine through holes can be replaced, which is very convenient and quick.
[0016] (ii) During the rotation of the mixing block, the inclined setting will form an oblique mixing trajectory. This trajectory expands the mixing range compared to the horizontally placed mixing block, allowing the grain and oil materials in the cooling box to be turned more fully, reducing the mixing dead corners, and making the heat dissipation more complete.
[0017] (III) The filter screen can effectively intercept impurities such as bran in hot air, preventing impurities from entering the water tank and polluting the water. The water supply pipe and spray head work together to backwash the filter screen, flushing the impurities to the drain outlet for centralized collection, making it easy to clean.

[0025] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0027] Given the current technology, existing cooling devices generally use the output shaft of a motor to drive a rotating shaft and auger blades to rotate, causing the raw materials inside the cylinder to tumble continuously, preventing heat from accumulating at the bottom of the cylinder. Then, a vacuum pump is used to guide the hot air inside the cylinder into a water tank, thereby achieving the purpose of heat dissipation. However, the efficiency of cooling the raw materials by rotating the auger blades to tumble the raw materials is relatively low, and the degree of tumbling of the raw materials at the edge of the cylinder and the central area is large, affecting the overall cooling effect.
[0028] like Figure 1-5 As shown, this utility model embodiment provides a cooling device for grain and oil processing, including a cooling box 1. The top of the cooling box 1 is provided with a feed inlet 101, and the side of the cooling box 1 is provided with a discharge outlet 102. The side of the cooling box 1 is provided with a transmission assembly 3, which includes a transmission rod 304. The interior of the cooling box 1 is provided with two transmission rods 304. The surface of the transmission rod 304 is provided with a plurality of first mounting holes 4. The surface of the transmission rod 304 is attached to a plurality of connecting blocks 401. The surface of the connecting block 401 is provided with two second mounting holes 402. The second mounting holes 402 are threadedly connected to the interior of the first mounting holes 403 with bolts 403. A connecting rod 404 is fixedly connected to one side of the connecting block 401. A stirring block 405 is fixedly connected to one side of the connecting rod 404. The surface of the stirring block 405 is provided with a through hole 406.
[0029] The grain and oil materials enter the cooling tank 1 through the feed inlet 101 at the top of the cooling tank 1. The transmission assembly 3 rotates the transmission rod 304. As the transmission rod 304 rotates, the connecting block 401 drives the connecting rod 404 and the stirring block 405 to rotate together. The stirring block 405 stirs the grain and oil materials in the cooling tank 1. During the stirring process, the grain and oil materials will continuously dissipate heat due to their high temperature. As the stirring block 405 continues to rotate, the grain and oil materials are constantly turned over, and the heat inside and the contact surface with the inner wall of the cooling box 1 can be dissipated into the surrounding air more quickly. In grain and oil processing, different types of grain and oil materials (such as soybeans, rapeseed, peanuts, sesame, etc.) have different physical properties (such as particle size, oil content, viscosity, etc.). Therefore, it is necessary to replace the stirring block 405 with different specifications to meet the processing requirements. When it is necessary to replace the stirring block 405, the connecting block 401 is attached to the surface of the transmission rod 304, so that the second mounting hole 402 on the surface of the connecting block 401 is aligned with the first mounting hole 4 at a suitable position on the surface of the transmission rod 304. Then, the bolt 403 is passed through the second mounting hole 402 and the first mounting hole 4 in sequence, and the bolt 403 is tightened to firmly fix the connecting block 401 on the transmission rod 304.
[0030] To improve cooling efficiency, when different sizes of mixing blocks 405 need to be replaced to suit processing requirements, operators can quickly remove the old mixing block 405 by loosening bolts 403 and install the new mixing block 405 by aligning it with the first mounting hole 4 and the second mounting hole 402. Different grains and oils have different particle sizes; for example, soybeans have larger particles, while wheat flour particles are smaller. For large particles like soybeans, a mixing block 405 with larger through holes 406 can be used, while for small particles like sesame seeds, a mixing block 405 with finer through holes 406 should be used. This is very convenient and quick. The design of the through holes 406 effectively reduces resistance during the turning process, making the material flow smoother, while accelerating air circulation between grains and oils, speeding up heat dissipation, and thus improving cooling efficiency.
[0031] Without the through-holes 406, the mixing block 405 could easily obstruct the overall flow of materials during mixing. The through-holes 406 provide more flow channels for the materials during mixing, preventing excessive accumulation on the surface of the mixing block 405. Taking wheat flour as an example, its fine particles and certain stickiness cause it to clump and accumulate on the mixing block 405 when mixed with a solid block; however, with the through-holes 406, the wheat flour can flow through, reducing accumulation and making the flow of grains and oils smoother.
[0032] Furthermore, a second gear 303 is fixedly connected to one side of the transmission rod 304, and a first gear 302 is meshed with the surface of the second gear 303. One end of the first gear 302 is fixedly connected to the output end of the motor 301.
[0033] After the motor 301 starts, its output end drives the first gear 302 to rotate. The first gear 302 meshes with the second gear 303, transmitting power to the second gear 303. The second gear 303 drives the transmission rod 304 to rotate, thereby realizing the rotational movement of the transmission rod 304 and providing power for the mixing block 405 to mix the grain and oil materials.
[0034] Furthermore, a water tank 5 is fixedly connected to one end of the cooling box 1, an exhaust fan 501 is fixedly connected to the top of the water tank 5, a connecting pipe 502 is fixedly connected to one end of the exhaust fan 501, the transmission port of the exhaust fan 501 is connected to the inside of the water tank 5, a water supply pipe 505 is fixedly connected to the top of the water tank 5, a spray head 506 is fixedly connected to the bottom of the water supply pipe 505, a filter screen 507 is provided at the bottom of the spray head 506, and a drain port 504 is provided at one end of the water tank 5.
[0035] The exhaust fan 501 starts, drawing out the hot air from the cooling box 1 and transporting it to the water tank 5 through the connecting pipe 502. The water tank 5 contains water; when the hot air enters the water, the heat is absorbed, thus cooling the air. The filter screen 507 filters out impurities such as bran from the drawn-in hot air. The water supply pipe 505 at the top of the water tank 5 supplies water to the tank 5 and discharges it from the outlet 503, forming a circulation. Water is also sprayed from the spray head 506 and sprayed onto the filter screen 507, flushing impurities towards the drain outlet 504 for easy collection.
[0036] The liquid level in water tank 5 is above the bottom of the transmission port. After impurities such as bran enter water tank 5, the filter screen 507 effectively intercepts impurities in the hot air, preventing them from entering water tank 5 and contaminating the water. After the grain and oil have cooled down, the water in water tank 5 is drained. Then, through the water supply pipe 505 and the spray head 506, the filter screen 507 is backwashed, flushing the impurities to the drain port 504 for collection and easy cleaning.
[0037] Furthermore, the angle of the stirring block 405 is inclined relative to the axial direction of the connecting rod 404, with an inclination angle ranging from 15° to 45°.
[0038] During rotation, the stirring block 405 is tilted so that it forms an oblique stirring trajectory. This trajectory expands the stirring range compared to a horizontally placed stirring block 405, allowing the grain and oil materials in the cooling box 1 to be more fully turned over, reducing stirring dead zones, and making heat dissipation more complete.
[0039] Furthermore, the first mounting holes 4 are arranged linearly at equal intervals along the surface of the transmission rod 304, and the spacing between two adjacent first mounting holes 4 is adapted to the mounting width of the connecting block 401.
[0040] When installing the connecting block 401, the first mounting hole 4 at a suitable position can be selected according to actual needs. The second mounting hole 402 on the surface of the connecting block 401 is aligned with the corresponding first mounting hole 4, and then fixed with bolts 403, thereby realizing the installation and adjustment of the connecting block 401 on the transmission rod 304.
[0041] Furthermore, the diameter of the first gear 302 is larger than the diameter of the second gear 303.
[0042] The transmission method of using a large gear to drive a small gear can increase the stirring speed and accelerate the cooling process of grain and oil materials while ensuring a certain torque.
[0043] Furthermore, heat-conducting plates 2 are fixedly connected to both ends of the cooling box 1, and reinforcing ribs 201 are fixedly connected to the surface of the heat-conducting plates 2.
[0044] The heat-conducting plate 2 is usually made of aluminum alloy because it is lightweight and conducts heat quickly. When the grain and oil materials dissipate heat in the cooling box 1, the heat is conducted through the outer wall of the cooling box 1 and then conducted to the surface of the heat-conducting plate 2, dissipating the heat to the surrounding environment. The reinforcing rib 201 assists in heat dissipation by enhancing the structural strength of the heat-conducting plate 2, while also increasing the structural strength.
[0045] Furthermore, the water tank 5 has an outlet 503 on the front, and both the outlet 503 and the water supply pipe 505 are equipped with a water stop valve in the middle.
[0046] The outlet 503 and the stop valve facilitate reasonable control and management of the water in the water tank 5.
[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
