DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 7 As shown, the present invention provides a heat exchange cage tube of an edible oil crystallization tank, comprising a heat exchange tube body 1, an inner wall of the heat exchange tube body 1 is provided with an adjustment mechanism 5, an outer wall of the heat exchange tube body 1 is provided with a water inlet pipe 4 and a water outlet pipe 3 through a connecting mechanism 2, the connecting mechanism 2 comprises a connecting flange 201, an outer wall of the connecting flange 201 is provided with a through groove 202, the inner wall of the connecting flange 201 is rotatably connected with a rotating block 203, the outer wall of the rotating block 203 is provided with an inclined groove 204, the inner wall of the connecting flange 201 is slidably connected with a connecting rod 205, the inner wall of the through groove 202 is slidably connected with a slider 206, the outer wall of the bottom end of the rotating block 203 is fixedly connected with a gear B210, the outer wall of the gear B210 is meshed with a gear A207, the top outer wall of the gear A207 is fixedly connected with a rotating rod 208, the outer wall of the rotating rod 208 is threadedly connected with a threaded block 209, and the outer walls of the water inlet pipe 4 and the water outlet pipe 3 are both fixedly connected with a fixed flange 7.

[0033] The heat exchange cage tube body 1 of the edible oil crystallization tank is a prior art. The upper and lower sides thereof can be connected to the water inlet pipe 4 and the water outlet pipe 3 respectively through the connecting mechanism 2 and installed inside the edible oil crystallization tank. When the edible oil is cooled and crystallized, the cooling medium can flow into the heat exchange tube body 1 through the water inlet pipe 4, and the heat exchange tube body 1 contacts with the edible oil for cooling and heat exchange, and then the cooling medium flows out through the water outlet pipe 3. The heat exchange tube body 1 and the water inlet pipe 4 and the water outlet pipe 3 can be assembled outside the crystallization tank and installed in the crystallization tank after the assembly is completed. The split design allows a group of heat exchange tube bodies 1 to be disassembled and replaced separately when they are damaged or aged, without the need to replace the entire heat exchange tube body 1, thereby saving maintenance costs.

[0034] like Figures 2 to 4 As shown, the connecting flange 201 is fixedly connected to the outer wall of the heat exchange tube body 1, and the gear A207 is rotatably connected to the inner wall of the connecting flange 201; one end of the connecting rod 205 is slidably connected to the inner wall of the inclined groove 204, and the other end of the connecting rod 205 is fixedly connected to the outer wall of the slider 206; the rotating rod 208 passes through the top outer wall of the connecting flange 201, and the threaded block 209 contacts the top outer wall of the connecting flange 201; the connecting flange 201 and the fixed flange 7 are connected by bolts, and threaded holes are provided on the outer walls of the fixed flange 7 and the slider 206.

[0035] By passing the bolts through the connecting flange 201 and the fixing flange 7, tightening the bolts in the threaded holes of the slider 206 and the fixing flange 7, and fixing them under the fixing flange 7 with nuts, the heat exchange tube body 1 can be connected and fixed to the water inlet pipe 4 or the water outlet pipe 3; and when the specifications of the heat exchange tube body 1 after replacement are different, and the positions of the threaded holes of the slider 206 and the fixing flange 7 do not correspond, the thread block 209 can be loosened to break contact with the top outer wall of the connecting flange 201, release the limit of the rotating rod 208, rotate the rotating rod 208, drive the gear A207 to rotate synchronously, and drive the gear B210 meshing with it to rotate; when the gear B210 rotates, the inner wall of the multiple groups of inclined grooves 204 squeezes one end of the connecting rod 205 of its inner wall, so that the connecting rod 205 and the slider 206 are synchronously rotated. The slider 206 is slidably connected to the inner wall of the connecting flange 201. When the connecting rod 205 drives the slider 206 to move, the multiple groups of sliders 206 can move synchronously outward or inward, so that the position of the threaded hole on the slider 206 can be adjusted; during the movement of the slider 206, the threaded hole always corresponds to the position of the through groove 202, and the bolt can pass through the through groove 202 and be threadedly connected in the threaded hole of the slider 206; by rotating the rotating rod 208, the position of the threaded hole on the slider 206 can be adjusted to correspond to the position of the threaded hole on the fixing flange 7, the bolt can be passed through the two groups of threaded holes, and the connecting flange 201 and the fixing flange 7 can be fixed by nuts, thereby avoiding the problem that the connecting flange 201 and the fixing flange 7 cannot be installed due to different threaded hole positions, and the adaptability is high.

[0036] When the position adjustment of the slider 206 is completed, the threaded block 209 can be rotated in the reverse direction to move the threaded block 209 downward until it contacts the top outer wall of the connecting flange 201. At this time, the rotating rod 208 can be limited to fix the gear A207, the gear B210 and the rotating block 203, thereby fixing the position of the connecting rod 205 and the slider 206 and maintaining the stability of the connection between the connecting flange 201 and the fixed flange 7.

[0037] like Figures 5 to 7 As shown, the adjustment mechanism 5 includes a moving rod 501, the inner wall of the moving rod 501 is slidably connected with two groups of wedge blocks 503, the two groups of wedge blocks 503 are elastically connected by a connecting spring 502, the outer wall of the moving rod 501 is fixedly connected with a fixing rod 504, the inner wall of the heat exchange tube body 1 is rotatably connected with a rotating shaft 506, the outer wall of the rotating shaft 506 is fixedly connected with a baffle 505, the outer wall of the rotating shaft 506 is fixedly connected with a sleeve rod 507, the inner wall of the sleeve rod 507 is slidably connected with an inner rod 508, the outer wall of the water inlet pipe 4 is fixedly connected with a fixing block 6, and the outer wall of the fixing block 6 is provided with a slot 8.

[0038] Three groups of baffles 505 are arranged on the inner wall of each group of heat exchange tube bodies 1. By moving the moving rod 501 up and down, the three groups of baffles 505 in each group of heat exchange tube bodies 1 can be turned over at the same time. When the baffles 505 are turned over to a vertical state, the resistance of the cooling medium is reduced, which is convenient for quickly conveying the cooling medium, accelerating the heat exchange efficiency and shortening the cooling time; when the baffles 505 are turned over to an inclined state, the flow rate of the cooling medium is reduced, and the edible oil has more time to fully exchange heat with the cooling medium, avoiding the temperature drop too fast and causing uneven temperature, thereby adapting to the needs of different production stages and being more flexible; the diameter of the baffle 505 is smaller than the inner diameter of the heat exchange tube body 1, that is, the outer wall of the baffle 505 does not contact the inner wall of the heat exchange tube body 1, so it can be turned over; the fixing rod 504 is fixed to the outer wall of the moving rod 501 by bolts. When the heat exchange tube body 1 needs to be replaced, the connecting flange 201 and the fixing flange 7 can be released, and then the bolts are unscrewed from the fixing rod 504 to remove the heat exchange tube body 1.

[0039] like Figures 5 to 7 As shown, the movable rod 501 is slidably connected to the inner wall of the fixed block 6, and the movable rod 501 passes through the outer wall of the fixed block 6; the fixed rod 504 is rotatably connected to the outer wall of the inner rod 508, and the rotating shaft 506 passes through the outer wall of the heat exchange tube body 1; the wedge block 503 is engaged with the slot 8, and the two ends of the connecting spring 502 are fixedly connected to the outer walls of the two groups of wedge blocks 503 respectively.

[0040] The slots 8 are provided with two groups, one above and one below, and each group of slots 8 is provided with two. When not affected by external forces, the two groups of wedge blocks 503 are ejected to both sides due to the elastic force of the connecting springs 502, and are engaged with the corresponding slots 8, fixing the position of the moving rod 501, thereby fixing the state of the baffle 505; when it is necessary to adjust the state of the baffle 505 according to production requirements, the two groups of wedge blocks 503 can be pressed to disengage them from the slots 8, thereby releasing the limit of the moving rod 501 and moving it up and down; if the wedge blocks 503 in the moving rod 501 are engaged with the slots 8 below at the beginning, the baffle 505 is in an inclined state at this time, and the moving rod 501 can be moved upward, driving the fixed plate 505 to move upward. The fixed rod 504 moves upward synchronously, causing the inner rod 508 and the sleeve rod 507 to flip over. During the flipping process, the inner rod 508 gradually moves to the inner wall of the sleeve rod 507. When the sleeve rod 507 flips over, it flips with the rotating shaft 506 as the center, driving the rotating shaft 506 to rotate synchronously, so that the baffle 505 can be rotated, so that the baffle 505 can be adjusted to a vertical state; in this state, the two groups of wedge blocks 503 correspond to the positions of the upper slots 8. Under the elastic force of the connecting spring 502, the wedge blocks 503 pop out and engage with the upper slots 8, so that the position of the moving rod 501 can be fixed, and the adjustment of the cooling medium flow rate in the heat exchange tube body 1 is completed, which can adapt to different production needs and is more flexible.

[0041] The present application also proposes a heat exchange method for a heat exchange cage tube of an edible oil crystallization tank, comprising the following steps:

[0042] S1. Correctly position the heat exchange tube body 1 in the crystallizer to ensure that it is in the proper position, fix the cage tube to the inner wall or bracket of the crystallizer to ensure that it is stable and avoid movement during operation, connect the heat exchange tube body 1 to the cold source, including the connection of the inlet and outlet pipes, ensure good sealing and avoid leakage;

[0043] S2. Check all connection points, seals and pipes to ensure that there is no water or air leakage, and ensure that all control systems and instruments are working properly, including temperature sensors, flow meters, etc. Perform preliminary cleaning on the heat exchange tube body 1 to remove impurities that may remain during production and installation, and conduct a trial run to confirm that the system is working properly without abnormal noise or leakage;

[0044] S3. According to production requirements, the flow rate of the cooling medium is adjusted through the adjustment mechanism 5. The two sets of wedge blocks 503 can be pressed and the moving rod 501 can be moved up and down to adjust the baffle 505 to an inclined or vertical state, thereby changing the flow rate of the cooling medium, adjusting the heat exchange efficiency according to production requirements, and fixing the state of the baffle 505;

[0045] S4. Start the cooling system as needed, cool the heat exchange medium to the set temperature, start the medium circulation pump, ensure that the refrigerant flows in the heat exchange tube body 1, exchange heat, monitor the temperature, flow and pressure in the crystallization tank in real time, ensure that the heat exchange process is carried out within the set range, maintain a stable crystallization environment, and adjust the flow, temperature and other parameters of the heat medium or refrigerant according to the monitoring data to optimize the heat exchange effect and crystallization process.

[0046] The working principle and use process of the present invention:

[0047] The heat exchange tube body 1 is connected to the water inlet pipe 4 and the water outlet pipe 3 through the connecting mechanism 2 to realize the inflow and outflow of the cooling medium. When installing the heat exchange tube body 1, when the position of the slider 206 does not correspond to the threaded hole of the fixed flange 7, the threaded block 209 can be loosened to release the limit of the rotating rod 208, and the rotating rod 208 is rotated to drive the gear A207 to rotate synchronously, and then drive the gear B210 meshing with it to rotate. When the gear B210 rotates, the inner wall of the multiple groups of inclined grooves 204 squeezes one end of the connecting rod 205, so that the connecting rod 205 and the slider 206 move synchronously. Since the slider 206 is slidably connected to the inner wall of the connecting flange 201, the multiple groups of sliders 206 can move synchronously to the outside or inside, so as to adjust the position of the threaded hole on the slider 206 so that the threaded hole corresponds to the position of the threaded hole of the fixed flange 7, and the bolt is passed through the through groove 202 on the connecting flange 201 and threadedly connected in the threaded hole of the slider 206.

[0048] When the position adjustment of the slider 206 is completed, the connecting flange 201 and the fixing flange 7 can be fixed by passing bolts through the threaded holes of the slider 206 and the fixing flange 7, and then the threaded block 209 can be rotated in the opposite direction to move the threaded block 209 downward until it contacts the top outer wall of the connecting flange 201. At this time, the rotating rod 208 can be limited to fix the gear A207, the gear B210 and the rotating block 203, thereby fixing the position of the connecting rod 205 and the slider 206 and maintaining the stability of the connection between the connecting flange 201 and the fixing flange 7.

[0049] By moving the moving rod 501 up and down, the three groups of baffles 505 in each group of heat exchange tube bodies 1 can be driven to flip at the same time. When the baffles 505 are flipped to a vertical state, the flow resistance of the cooling medium is reduced, which facilitates the rapid delivery of the cooling medium, accelerates the heat exchange efficiency, and shortens the cooling time; when the baffles 505 are flipped to an inclined state, the flow rate of the cooling medium is reduced, and the edible oil has more time to fully exchange heat with the water, avoiding uneven temperature caused by excessively rapid temperature drop, and adapting to the needs of different production stages.

[0050] When it is necessary to adjust the state of the baffle 505 according to production requirements, the two groups of wedge blocks 503 can be pressed to disengage them from the slot 8, so that the limit of the moving rod 501 can be released to move it upward, driving the fixed rod 504 to move upward synchronously, so that the inner rod 508 and the sleeve rod 507 can be flipped. During the flipping process, the inner rod 508 gradually moves into the inner wall of the sleeve rod 507. When the sleeve rod 507 flips, it drives the rotating shaft 506 to rotate synchronously, so that the baffle 505 can be rotated, so that the baffle 505 can be adjusted to a vertical state; in this state, the two groups of wedge blocks 503 correspond to the positions of the upper slot 8. Under the elastic force of the connecting spring 502, the wedge block 503 pops out and engages with the upper slot 8, so that the position of the moving rod 501 can be fixed, and the water flow rate in the heat exchange tube body 1 can be adjusted to meet different production requirements; and by pressing the wedge block 503 and moving the moving rod 501 downward, the baffle 505 can be adjusted to a tilted state, thereby reducing the flow rate of the cooling medium and making flexible adjustments.
