Description

Technical Field

[0001] The present invention belongs to the technical field of heat exchange, and particularly relates to a heat exchanger for casing production. Background Art

[0002] During the production of casings, a steaming step is required. In the actual processing, natural casings such as pig casings or collagen casings are sensitive to temperature. Temperature fluctuations can cause protein denaturation and shrinkage or heat stress concentration, resulting in rupture or deformation. At the same time, the steaming temperature of natural casings needs to be strictly controlled within the range of 75 - 85°C. Too high a temperature will damage their elasticity and water retention, affecting subsequent drug encapsulation or slow-release functions. Too low a temperature will lead to incomplete steaming effect or low steaming efficiency of natural casings. Therefore, a heat exchanger is required to strictly control the steaming temperature of natural casings according to production requirements.

[0003] In the prior art, when steaming and processing natural casings, there is a method of using a heat exchange channel as a part of a tank filled with fluid or a heat exchanger attached to the tank to complete the heat supplement for the moisture of the steamed casings. However, in the prior art, the traditional heat exchanger cannot efficiently and uniformly supplement heat to the fluid in the internal heat exchange channel of the heat exchanger, the heat supplement effect cannot be accurately controlled, and the efficiency is low. Summary of the Invention

[0004] In view of this, the technical problem to be solved by the present invention is to provide a heat exchanger for casing production, which can efficiently and uniformly supplement heat to the fluid in the internal heat exchange channel of the heat exchanger and accurately and efficiently complete the heat supplement effect.

[0005] A heat exchanger for casing production includes a heat exchange plate, on which an upper pipe and a lower pipe are fixedly connected. A plurality of guiding strips are arranged inside the heat exchange plate, and the plurality of guiding strips are arranged staggeredly. The inclination directions of two adjacent guiding strips among the plurality of guiding strips are opposite. A plurality of spiral parts are arranged between the upper pipe and the lower pipe.

[0006] It also includes a partition plate fixedly connected inside the upper pipe. An outlet pipe and an inlet pipe are fixedly connected to the upper pipe, and the outlet pipe and the inlet pipe are respectively located on the left and right sides of the partition plate.

[0007] It also includes a vertical rod fixedly connected between the upper pipe and the lower pipe. A moving part is slidably connected to the vertical rod. A heating part is fixedly connected to the moving part. A rotating part is rotatably connected to the heating part. A transmission part is fixedly connected to the heating part.

[0008] It also includes a knocking plate fixedly connected to the sliding rod.

[0009] The beneficial effects of this device are as follows:

[0010] It can efficiently and uniformly supplement heat to the fluid in the internal heat exchange channels of the heat exchanger, accurately and efficiently achieve the heat supplement effect. Multiple guiding strips with different inclination directions and arranged in a staggered manner can force the liquid medium in the device to repeatedly change directions during the flow process, forming local turbulence, effectively destroying the fluid boundary layer, and reducing the thermal resistance.

[0022] A heat exchanger for casing production includes a heat exchange plate 101. The inside of the heat exchange plate 101 is a hollow structure. An upper pipe 501 and a lower pipe 502 are fixedly connected to the heat exchange plate 101. A plurality of guiding strips 102 are arranged inside the heat exchange plate 101. The plurality of guiding strips 102 are arranged in a staggered manner. The inclination directions of two adjacent guiding strips 102 among the plurality of guiding strips 102 are opposite. A plurality of spiral parts 201 are arranged between the upper pipe 501 and the lower pipe 502. There is a gap between the plurality of spiral parts 201. The gap between the plurality of spiral parts 201 is filled by welding a supplementary sleeve into the gap.

[0023] After introducing a liquid cooling medium into the upward pipe 501, the liquid cooling medium enters the heat exchange plate 101 through the upper pipe 501. After the cooling medium completely passes through the heat exchange plate 101, it is discharged through the lower pipe 502. Subsequently, the liquid medium enters into a plurality of spiral portions 201 and spirally ascends along the plurality of spiral portions 201 until it returns to the upper pipe 501 and then the above operations are cycled. That is, the flow path of the liquid cooling medium is successively the upper pipe 501, the heat exchange plate 101, the lower pipe 502, the plurality of spiral portions 201, and then back to the upper pipe 501 for circulation. And the heat exchange plate 101 is formed into the outer wall of a tank container. Subsequently, water and casings are added into the tank container, and then the casings are steamed. During this process, since a plurality of guiding strips 102 are provided inside the heat exchange plate 101, and the plurality of guiding strips 102 are arranged in a staggered manner and the inclination directions of two adjacent guiding strips 102 among the plurality of guiding strips 102 are opposite, the liquid cooling medium will be guided by the plurality of guiding strips 102 after entering the heat exchange plate 101, so as to form a flow situation from top to bottom and continuously reciprocating left and right in the heat exchange plate 101, enabling the liquid medium to be in full contact with the heat exchange plate 101. Furthermore, the heat carried by the liquid medium is used to uniformly heat the surface of the heat exchange plate 101 in an all-round manner, so that the water in the container can be uniformly heated after contacting the surface of the heat exchange plate 101. Ensure that during the heating process of the casings, the temperature can always be uniformly maintained at 80 °C, realizing precise temperature control operation, and avoiding the situation of casing rupture or uneven steaming caused by temperature fluctuations;

[0024] The plurality of guiding strips 102 with different inclination directions and arranged in a staggered manner can force the liquid medium to repeatedly change its direction during the flow in the device, forming local turbulence. This flow state can effectively break the fluid boundary layer, reduce the thermal resistance. At the same time, the "S-shaped" reciprocating flow between the water guide plates also prolongs its residence time in the heat exchanger, making the heat exchange between the cold and hot media more sufficient.

[0025] Furthermore, the opposite inclination directions of adjacent water guide plates guide the fluid to alternately contact different regions of the heat exchange plate, which can prevent local overheating or insufficient cooling.

[0026] During actual use, multiple spiral parts 201 can be continuously and evenly heated. When the fluid circulates upward in the upper pipe 501 through the multiple spiral parts 201, the heat in the multiple spiral parts 201 will be supplemented into the fluid, thereby ensuring that the fluid can always stably maintain its own heat during the circulation process, so as to ensure the overall temperature stability of the heat exchange plate 101 and further achieve the precise temperature control effect. When the fluid flows upward along the bottom of the heat exchange plate 101, the heat continuously released by the pipe wall is evenly supplemented into the fluid by gradually contacting the fluid, avoiding a large sudden change in the local temperature, which may lead to uneven heat in the subsequent process. At the same time, the overall spiral pipe composed of multiple spiral parts 201 can reduce the flow dead zone through the multi-layer coaxial channel structure and self-supporting characteristics, further enabling the fluid to be evenly supplemented with heat. At the same time, compared with the method of directly heating the heat exchange plate 101, supplementing heat to the fluid can make the temperatures at various positions on the subsequent heat exchange plate 101 more uniform, achieving the effect of uniform heat supplement and being more likely to achieve the precise temperature control effect.

[0027] Furthermore, the multiple spiral parts 201 can be unevenly heated so that the temperatures of the multiple spiral parts 201 gradually increase from bottom to top. Thus, when the fluid flows through, its temperature can be gradually increased. Since the spiral pipe increases the flow path of the fluid, when the fluid flows through the spiral pipe, it can be gradually supplemented with heat by the multiple spiral parts 201 whose temperatures are gradually increased, achieving the effect of gradual heat supplement, thereby further improving the uniformity of the heat supplement effect, ensuring that the fluid has a stable temperature, and achieving the precise temperature control effect.

[0028] During actual use, a water pump can be connected in the tank container, and the water pump can circulate and pump out the water in the tank container, making the water in the container flow, which further facilitates the uniform contact of the water with the front side of the heat exchange plate 101, thereby further precisely controlling the water temperature at 80 °C to ensure the subsequent steaming effect;

[0029] Furthermore, according to actual use requirements, two of this device can be formed on the outer wall of the tank container or the four outer walls of the tank container can be formed by this device, which further facilitates the uniform heating of the water in the container and further achieves the precise temperature control effect.

[0030] It also includes a partition plate 105 fixedly connected in the upper pipe 501. An outlet pipe 103 and an inlet pipe 104 are fixedly connected to the upper pipe 501, and the outlet pipe 103 and the inlet pipe 104 are respectively located on the left and right sides of the partition plate 105.

[0031] During actual use, a pump body A can be installed on the upper pipe 501 by tightening bolts, and the water inlet pipe and the liquid outlet pipe 103 of the pump body A are connected and sealed by bolts. Subsequently, the water outlet pipe of the pump body A and the liquid inlet pipe 104 are connected and sealed by bolts. After the fluid is pushed from bottom to top along the spiral part 201 into the upper pipe 501, the fluid will be blocked by the partition plate 105. Then, the pump body A is used to extract the fluid with heat and inject the fluid into the liquid inlet pipe 104, thereby increasing the flow pressure of the fluid and enabling the fluid to continuously flow along the circulation track composed of the upper pipe 501, the heat exchange plate 101, the lower pipe 502, and multiple spiral parts 201, achieving the continuous movement effect of the fluid;

[0032] After the processing is completed, the water outlet pipe of the pump body A can be removed from the liquid inlet pipe 104, and then the fluid is discharged through the water outlet pipe. Subsequently, the fluid can be filtered outside the equipment to remove impurities in the fluid, thereby avoiding blockage of the inside of the heat exchange plate 101 by impurities after long-term use and affecting the subsequent smooth flow effect of the fluid.

[0033] It further includes a vertical rod 701 fixedly connected between the upper pipe 501 and the lower pipe 502. A moving part 303 is slidably connected to the vertical rod 701. A heating part 301 is fixedly connected to the moving part 303. A matching hole is formed in the moving part 303, and the vertical rod 701 passes through the matching hole to achieve a sliding connection. A rotating part 302 is rotatably connected to the heating part 301. A sliding rod 306 is slidably connected to the rotating part 302. A second motor is fixedly connected to the heating part 301. A gear is fixedly connected to the output shaft of the second motor. A toothed ring is fixedly connected to the rotating part 302. The gear meshes with the toothed ring. A temperature sensor is fixedly connected to the front end of the sliding rod 306. A circular plate is fixedly connected to the rotating part 302. A through hole is formed in the circular plate, and the sliding rod 306 and the circular plate are slidably connected through the through hole. A first electric push rod is fixedly connected to the rotating part 302, and the first electric push rod is fixedly connected to the sliding rod 306. A transmission part 304 is fixedly connected to the heating part 301. A first motor is fixedly connected to the upper pipe 501. A first lead screw is rotatably connected to the output shaft of the first motor. The first lead screw is threadedly connected to the transmission part 304. A storage battery is fixedly connected to the rotating part 302, and the storage battery supplies power to the first motor and the temperature sensor to avoid wire entanglement. An electric heating wire is fixedly connected inside the heating part 301.

[0034] Operate the first lead screw to rotate, so that the first lead screw drives the transmission part 304 to move, causing the heating part 301 to perform a reciprocating sliding operation up and down under the limitation of the moving part 303. During this process, the electric heating wire inside the heating part 301 is continuously started, thereby using the electric heating wire to heat the outer walls of multiple spiral parts 201, enabling multiple spiral parts 201 to have sufficient heat and stably realizing the subsequent fluid heat supplement operation;

[0035] During the reciprocating sliding of the heating part 301 up and down, the operating rotating part 302 continuously rotates on the heating part 301, enabling the sliding rod 306 and the temperature sensor at the front end of the sliding rod 306 to move along a spiral trajectory. Consequently, the temperature sensor can come into full contact with various positions of the overall spiral tube formed by multiple spiral parts 201, thereby sensing the temperatures at different positions of the spiral tube. Subsequently, based on the detected data, different degrees and durations of heating effects can be applied to different positions of the spiral tube, achieving the subsequent functions of uniform heat supplement or gradual heat supplement.

[0036] It also includes a percussion plate 305 fixedly connected to the sliding rod 306.

[0037] During the operation of the device, when the sliding rod 306 is moved along the spiral trajectory, the sliding rod 306 can be operated to slide on the rotating part 302, causing the percussion plate 305 on the sliding rod 306 to periodically strike various positions on the multiple spiral parts 201. As a result, the multiple spiral parts 201 vibrate periodically during operation, shaking off the impurities that may adhere to the inside of the spiral parts 201 and preventing the situation where impurities adhere to the inner wall of a certain spiral part 201 among the multiple spiral parts 201, causing blockage and affecting the subsequent fluid circulation effect.

[0038] The vertical rod 701 has a hollow structure. A pump body B is provided at the bottom end inside the vertical rod 701. An arc-shaped plate 106 is fixedly connected between the upper pipe 501 and the lower pipe 502, and an electric heating plate is provided on the arc-shaped plate 106.

[0039] If the overall spiral tube formed by multiple spiral parts 201 becomes blocked and is unable to continue the fluid circulation operation, the pump body B can be started. The pump body B is used to transport the fluid at the bottom of the vertical rod 701 upward, and then directly transported to the right side of the partition plate 105 through the vertical rod 701. Thus, the vertical rod 701 is used to replace the multiple spiral parts 201 to complete the fluid transportation operation, avoiding the situation where the heat exchange work cannot be carried out normally when a single channel is blocked.

[0040] When using the vertical rod 701 as a temporary fluid transportation channel, the arc-shaped plate 106 can be started to provide heat to the vertical rod 701 by the arc-shaped plate 106, ensuring that the fluid can still be smoothly supplemented with heat during temporary flow and ensuring the normal progress of the heat exchange operation.

[0041] It also includes a switching rod 601 slidably connected to the lower pipe 502, and a second electric push rod capable of pushing the switching rod 601 to slide is fixedly connected to the lower pipe 502.

[0042] Under normal conditions, the switching rod 601 is in Figure 5The position shown ensures that the fluid can circulate through the passage formed by the upper tube 501, the heat exchange plate 101, the lower tube 502, and the multiple spiral parts 201. When the integral spiral tube formed by the multiple observation parts 202 is blocked, the switch rod 601 is operated to slide on the lower tube 502 and move the switch rod 601 to the right side of the vertical rod 701. At this time, the switch rod 601 can block the fluid and block the fluid at the lower side of the vertical rod 701, thereby facilitating the subsequent operation of pumping the fluid upward.

[0043] Each spiral portion 201 is provided with an observation portion 202 , and each spiral portion 201 is provided with a marking portion 203 , which can slide along the inner wall of the spiral portion 201 . A baffle is provided at the top of each spiral portion 201 to prevent the marking portion 203 from sliding out of the spiral portion 201 .

[0044] After the gaps between the multiple spiral parts 201 are filled by welding supplementary sleeves into the gaps so that the multiple spiral parts 201 form an integral spiral tube, when the fluid is transported upward through the multiple spiral parts 201, if there is no blockage in the multiple spiral parts 201, the fluid will push the multiple marking parts 203 to slide inside the multiple spiral parts 201 respectively, so that the multiple marking parts 203 can be respectively pressed against the position where the uppermost observation part 202 of the multiple spiral parts 201 is located, thereby allowing the staff to accurately judge the fluid flow situation inside the multiple spiral parts 201 by whether the multiple marking parts 203 are in a position that can be directly observed through the multiple observation parts 202;

[0045] When a blockage occurs, the fluid cannot continue to flow through a blocked spiral portion 201, and the marking portion 203 in the spiral portion 201 will naturally slide to a position offset from the observation portion 202 due to gravity, similar to a rotating slide structure, so that the staff can quickly find the specific location of the blockage, and then cut and disassemble the blocked spiral portion 201, and then perform a separate replacement or maintenance and dredging operation on the blocked spiral portion 201 to complete the maintenance effect. The split design of multiple spiral portions 201 can reduce the subsequent operation and maintenance costs. At the same time, the provision of multiple marking portions 203 can facilitate the staff to quickly and accurately grasp the location of the blockage, which brings convenience to subsequent operation and maintenance.

[0046] A through groove is provided inside the marking part 203 to ensure that the fluid can pass normally. The marking part 203 is also a spiral structure to ensure that it can slide smoothly inside the spiral part 201. An arc chamfer is provided at the tail of the marking part 203 to reduce the possibility of impurities getting stuck at the tail of the marking part 203.

[0047] It also includes a filtering part 401 detachably connected to the upper pipe 501 through bolts. The right side of the upper pipe 501 is an open structure. During actual use, the right side of the upper pipe 501 is closed by means of a bolt baffle and sealing.

[0048] The filtering part 401 can filter the fluid during the circulation process, effectively remove the impurities carried by the fluid, and avoid the situation that the impurities enter the pump body and affect the service life of the pump body.

[0049] After using for a period of time, the baffle on the right side of the upper pipe 501 can be removed, and then the filtering part 401 can be removed by loosening the bolts to replace the filtering part 401, so as to ensure the filtering effect of the filtering part 401 for a long time.

[0050] It also includes an inverted U-shaped plate 801 fixedly connected to the upper pipe 501. A T-shaped rod 802 is slidably connected to the inverted U-shaped plate 801, and a compression spring is fixedly connected between the inverted U-shaped plate 801 and the T-shaped rod 802.

[0051] When the fluid passes through the lower side of the T-shaped rod 802, the fluid will push the T-shaped rod 802 to slide upward against the elastic force of the compression spring, so that the staff can observe whether the fluid is continuously flowing by observing the sliding condition of the T-shaped rod 802 outside the equipment. If the fluid is blocked, the T-shaped rod 802 will slide downward on the upper pipe 501, and then the staff can start the temporary standby channel vertical rod 701 in time to ensure the stable operation of the equipment.

[0052] It also includes two auxiliary plates 108 fixedly connected to the heat exchange plate 101. The two auxiliary plates 108 are respectively located at the through connection positions of the upper pipe 501, the lower pipe 502 and the heat exchange plate 101. A matching plate 107 is detachably connected to the heat exchange plate 101 through bolts, and a sealing is arranged between the matching plate 107 and the heat exchange plate 101.

[0053] The two auxiliary plates 108 can guide and intercept the fluid entering and discharging from the heat exchange plate 101, so that the fluid can smoothly move up and down and reciprocate left and right along a plurality of guide strips 102, ensuring that the fluid can continuously circulate smoothly and complete the subsequent heat exchange work.

[0054] After the equipment stops running, the matching plate 107 can be removed from the heat exchange plate 101, so as to clean the surfaces of the plurality of guide strips 102 and avoid the situation that impurities adhere to the surfaces of the plurality of guide strips 102 and affect the subsequent fluid flow effect.
