Description

Technical Field

[0001] This utility model relates to the technical field of cooling machine devices, and in particular to a cooling device for a cooling machine. Background Technology

[0002] The cooling device for a slab cooling machine is a core auxiliary equipment used in slab cooling machines. It primarily uses a liquid medium as an intermediate heat transfer carrier, working in conjunction with the coolant flowing within the heat exchange tubes to achieve heat exchange, thereby cooling the materials within the cooling chamber. It is widely used in food processing, pharmaceutical manufacturing, chemical production, and other fields requiring rapid cooling of granular, flaky, or lumpy materials. It effectively controls material temperature, ensures material quality, and meets the process requirements for subsequent processing or storage.

[0003] Existing cooling devices for slab cooling machines still have many shortcomings in practical use. First, the liquid medium is prone to poor flow or stratification in the cooling box, resulting in insufficient and uneven contact between the liquid medium and the heat exchange tubes, leading to low heat exchange efficiency. This, in turn, affects the cooling speed and uniformity of the material, making it difficult to meet the needs of high-efficiency production. Second, after long-term use, impurities or dirt easily accumulate on the surface of the heat exchange tubes. Existing devices lack a dedicated cleaning structure, making it impossible to clean the surface of the heat exchange tubes in a timely manner. As dirt accumulates, the heat exchange capacity of the heat exchange tubes gradually decreases, further reducing the cooling effect. This also requires manual cleaning during shutdown, increasing maintenance costs and downtime, and affecting the continuous and stable operation of the equipment.

[0004] Therefore, it is necessary to provide a new cooling device for a cooling machine to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a cooling device for a slicing machine.

[0006] The cooling device for a slab cooling machine provided by this utility model includes: a slab cooling box, into which a liquid medium is poured, used to cool the material; a heat exchange tube fixedly connected inside the slab cooling box, through which a coolant flows, used to cool the liquid medium; multiple sets of stirring rollers rotatably connected inside the slab cooling box, used to stir the liquid medium; multiple sets of cleaning rollers rotatably connected at equal intervals inside the slab cooling box, used to clean the surface of the heat exchange tube; and a partition fixedly connected above the stirring rollers inside the slab cooling box, with multiple through openings equidistantly opened on the surface of the partition, the size of which is smaller than the size of the material, used to block the material above the partition.

[0007] Preferably, the outer wall of the stirring roller is fixedly connected with stirring plates at equal intervals. The stirring plates are arc-shaped, and the stirring roller drives the stirring plates to rotate towards the concave surface of the stirring plates.

[0008] Preferably, a first pulley is symmetrically rotatably connected to one side of the cooling box, and a second pulley is rotatably connected inside the cooling box between the two first pulleys. The diameter of the second pulley is larger than that of the first pulley, and the second pulley and the two first pulleys are connected by belt drive. One end of the multiple sets of stirring rollers is fixedly connected to the first pulley and the second pulley, respectively.

[0009] Preferably, a first motor is fixedly connected to one side of the cooling box, and one of the two first pulleys is fixedly connected to the output end of the first motor.

[0010] Preferably, multiple sets of short bristles are fixedly connected at equal intervals to the sidewall of the cleaning roller, and multiple sets of long bristles are fixedly connected to the sidewall of the cleaning roller above and below the short bristles.

[0011] Preferably, the bottom of the cooling box is symmetrically rotatably connected to multiple sets of worm gears, and the multiple sets of worm gears are respectively fixedly connected to the bottom of the cleaning roller. The bottom of the cleaning roller is symmetrically fixedly connected to a worm, and the worm meshes with the worm gears.

[0012] Preferably, the cooling box has driven gears symmetrically rotatably connected inside, and the two driven gears are respectively fixedly connected to one end of the worm gear; the cooling box also has a driving gear rotatably connected inside, and the two driven gears mesh with the driving gear.

[0013] Preferably, a second motor is fixedly connected to the bottom of the cooling box, and the output end of the second motor is fixedly connected to the drive gear.

[0014] Compared with related technologies, the cooling device for the slicing machine provided by this utility model has the following beneficial effects: I. Improve heat exchange efficiency and ensure material cooling effect

[0015] This invention features multiple horizontally mounted stirring rollers with arc-shaped stirring plates fixedly connected to their outer walls. During stirring, the stirring plates rotate towards the concave side, creating a "scraping" and directional pushing effect on the liquid medium above. This design effectively drives the liquid medium to form an active flow circulation within the cooling tank, breaking down temperature stratification caused by heat exchange and promoting thorough mixing of the upper and lower layers, resulting in a more uniform liquid medium temperature. Simultaneously, the contact frequency and contact area between the flowing liquid medium and the heat exchange tubes are significantly increased, greatly improving the heat exchange efficiency between the coolant and the liquid medium. This ensures that the material above the partition can fully contact the low-temperature liquid medium, achieving rapid and uniform cooling and meeting the requirements of high-efficiency production for material cooling quality.

[0016] II. Achieve automatic cleaning of heat exchange tubes, reducing maintenance costs.

[0017] This invention is equipped with multiple sets of cleaning rollers. The long and short bristles on the sidewalls of the cleaning rollers can be adapted to the arc-shaped structure of the outer wall of the heat exchange tube. The short bristles fit against the middle arc surface of the heat exchange tube, while the long bristles cover the upper and lower arc surfaces of the heat exchange tube, achieving all-round coverage of the outer wall of the heat exchange tube. Under the transmission action of the second motor, driving gear, driven gear, worm gear, and worm wheel, the cleaning rollers can rotate synchronously, driving the bristles to rub against the surface of the heat exchange tube, automatically removing impurities and dirt adhering to the surface of the heat exchange tube. This structure eliminates the need for manual cleaning during machine shutdown, not only avoiding the problem of reduced heat exchange efficiency caused by dirt accumulation, but also reducing manual maintenance costs and equipment downtime, ensuring continuous and stable operation of the cooling device.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] Please see Figures 1 to 4A cooling device for a slicing machine includes: a slicing box containing a liquid medium for cooling materials; a heat exchange tube fixedly connected inside the slicing box, through which coolant flows for cooling the liquid medium; multiple sets of stirring rollers rotatably connected inside the slicing box for stirring the liquid medium; multiple sets of cleaning rollers rotatably connected at equal intervals inside the slicing box for cleaning the surface of the heat exchange tube; and a partition fixedly connected above the stirring rollers inside the slicing box, with multiple through openings at equal intervals on the surface of the partition, the size of which is smaller than the size of the material, the partition for blocking the material above the partition.

[0023] It should be noted that the stirring roller is installed horizontally, while the cleaning roller is installed vertically; the baffles prevent the material from coming into contact with the stirring roller and heat exchange tube.

[0024] Please see Figure 2 and Figure 3 A stirring plate is fixedly connected at equal intervals to the outer wall of the stirring roller. The stirring plate has an arc-shaped design. The stirring roller drives the stirring plate to rotate towards the concave surface of the stirring plate. A first pulley is symmetrically rotatably connected to one side of the cooling box. A second pulley is rotatably connected inside the cooling box between the two first pulleys. The diameter of the second pulley is larger than that of the first pulley. The second pulley and the two first pulleys are connected by belt drive. One end of the multiple sets of stirring rollers is fixedly connected to the first pulley and the second pulley, respectively. A first motor is fixedly connected to one side of the cooling box. One of the two first pulleys is fixedly connected to the output end of the first motor.

[0025] It should be noted that when the arc-shaped stirring plate on the outer wall of the stirring roller rotates towards the concave direction along with the horizontally installed stirring roller, it can "scrape" and directionally push the liquid medium above through the concave structure. This drives the liquid medium to form an active flow circulation in the cooling box, breaks up temperature stratification and promotes the mixing of the upper and lower layers of the medium. It also increases the contact frequency and uniformity between the liquid medium and the heat exchange tube, thereby improving the heat exchange efficiency, ensuring the temperature of the liquid medium in the cooling box is consistent, and ultimately improving the cooling uniformity and cooling efficiency of the material above the partition.

[0026] Please see Figures 2 to 4The cleaning roller has multiple sets of short bristles fixedly connected at equal intervals on its sidewalls, and multiple sets of long bristles fixedly connected above and below the short bristles on the sidewalls of the cleaning roller. Multiple sets of worm gears are symmetrically rotatably connected to the bottom of the cooling box, and each set of worm gears is fixedly connected to the bottom of the cleaning roller. A worm is symmetrically fixedly connected to the bottom of the cleaning roller, and the worm meshes with the worm gears. Driven gears are symmetrically rotatably connected inside the cooling box, and two driven gears are fixedly connected to one end of the worm. A driving gear is rotatably connected inside the cooling box, and both driven gears mesh with the driving gear. A second motor is fixedly connected to the bottom of the cooling box, and the output end of the second motor is fixedly connected to the driving gear.

[0027] It should be noted that the long and short bristles on the sidewall of the cleaning roller work together to fit the cylindrical arc surface structure of the heat exchange tube. The short bristles fit against the middle arc surface of the outer wall of the heat exchange tube, while the long bristles cover the upper and lower arc surfaces of the outer wall of the heat exchange tube. When the cleaning roller rotates, both the long and short bristles rub tightly against the surface of the heat exchange tube, thereby removing impurities and dirt from all areas of the outer wall of the heat exchange tube in an all-round way, and preventing the heat exchange efficiency from decreasing due to the accumulation of impurities.

[0028] The working principle of the cooling device for the slicing machine provided by this utility model is as follows: I. Cooling Process

[0029] The material is fed into the cooling box and placed above the partition. The cooling box is pre-filled with an appropriate amount of liquid medium (the liquid medium level exceeds the partition). Multiple sets of through openings equidistantly on the surface of the partition are smaller than the material size, which prevents the material from falling into the liquid medium below the partition, keeping the material stably above the partition and in contact with the liquid medium.

[0030] Coolant continuously flows through heat exchange tubes fixedly connected inside the cooling box. The coolant exchanges heat with the liquid medium through the tube walls, absorbing heat from the liquid medium and lowering its temperature. The low-temperature liquid medium then exchanges heat with the material above the baffle, absorbing heat from the material and cooling it down, thus completing the cooling process.

[0031] II. Mixing Process

[0032] After the first motor, which is fixedly connected to one side of the cooling box, is started, its output end drives a first pulley, which is fixedly connected to it, to rotate. Since the two first pulleys, which are symmetrically rotatably connected to one side of the cooling box, are connected to the second pulley located between them inside the cooling box via belt drive, and the diameter of the second pulley is larger than that of the first pulley, when one of the first pulleys rotates, it will drive the other first pulley and the second pulley to rotate synchronously via the belt.

[0033] Multiple sets of stirring rollers are horizontally installed inside the cooling box, with one end fixedly connected to the first and second pulleys respectively. As the pulleys rotate, the stirring rollers rotate horizontally inside the cooling box. Arc-shaped stirring plates, equidistantly fixed to the outer wall of the stirring rollers, rotate synchronously with the stirring rollers, and the stirring rollers drive the stirring plates to rotate towards the concave surface of the stirring plates.

[0034] During rotation, the concave structure of the arc-shaped stirring plate creates a "scraping" effect, which can scrape down the liquid medium above the stirring roller and push it in a specific direction. This directional scraping and pushing action not only makes the liquid medium form a more active flow circulation in the cooling box, but also breaks up the stratification of the liquid medium, forcibly promoting the mixing of the upper and lower layers of liquid medium. This allows for more thorough and uniform contact between the liquid medium and the heat exchange tubes, effectively improving heat exchange efficiency. At the same time, it ensures that the overall temperature of the liquid medium in the cooling box is consistent, significantly improving the cooling uniformity and cooling efficiency of the material above the baffle.

[0035] III. Cleaning Process

[0036] After the second motor, which is fixedly connected to the bottom of the cooling box, is started, its output end drives the drive gear, which is fixedly connected to it, to rotate. The drive gear, which is rotatably connected inside the cooling box, meshes with two symmetrically arranged driven gears. Therefore, when the drive gear rotates, it drives the two driven gears to rotate synchronously in opposite directions.

[0037] Two driven gears are fixedly connected to one end of a worm gear that is symmetrically rotatable inside the cooling box. The worm gear rotates synchronously with the driven gears. The worm gear meshes with multiple sets of worm wheels that are symmetrically rotatable at the bottom of the cooling box. When the worm gear rotates, it drives the worm wheels to rotate, which in turn drives the cleaning roller to rotate inside the cooling box.

[0038] Multiple sets of short bristles, which are fixedly connected at equal intervals on the side wall of the cleaning roller, and multiple sets of long bristles located above and below the short bristles, rotate synchronously with the cleaning roller. During the rotation, the bristles come into contact with the surface of the heat exchange tube and generate friction, thereby removing impurities or dirt that may be attached to the surface of the heat exchange tube. This prevents impurities from affecting the heat exchange efficiency between the heat exchange tube and the liquid medium, and ensures the long-term stable operation of the cooling device.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
