Description

Technical Field

[0001] This utility model relates to the field of shrinkage reducer technology, and in particular to a shrinkage reducer with a leak-proof structure. Background Technology

[0002] A shrinkage reducer is a device used to reduce an original sample to an appropriate amount while retaining its representativeness. It is mainly used in laboratory or industrial production for sample preparation of non-uniform granular materials. In order to reduce gas or liquid leakage during operation, a shrinkage reducer with a leak-proof structure is used.

[0003] To address this, patent CN210419271U discloses an ammonia stripping and shrinking device that can reduce resistance. The device includes an ammonia stripping tower, with the ammonia stripping and shrinking device fixedly installed on the top. The device includes a shell, with a water injection pipe fixedly connected to one side of the top of the shell and a water outlet pipe fixedly connected to one side of the bottom of the shell. This invention employs a serpentine tube array, with increased spacing and inner diameter, resulting in a larger heat exchange area and improved heat exchange efficiency. Simultaneously, the increased inner diameter and thinner tube walls, according to the heat transfer coefficient formula, indicate lower scale resistance and a higher heat transfer coefficient, thus further improving heat exchange efficiency. Furthermore, the increased spacing between the serpentine tubes effectively reduces the overall system resistance. Additionally, the outer wall of the serpentine tubes is coated with an anti-scaling layer, a titanium-sodium nano-coating, to prevent scale buildup, effectively reducing the likelihood of blockage between the tubes and extending the equipment's service life.

[0004] Although the anti-scaling layer of the aforementioned ammonia condenser, which can reduce resistance, is made of titanium nanofiber coating to prevent scale buildup and effectively reduce the chance of blockage between the serpentine tubes, its applicability is low because it is inconvenient to improve the heat exchange effect and to make it difficult for the components in the mixed medium that need to be condensed to undergo phase transformation more quickly and fully. Utility Model Content

[0005] The purpose of this invention is to provide a shrinkage unit with a leak-proof structure to solve the problem that existing shrinkage units with leak-proof structures are not conducive to improving heat exchange efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a shrinkage device with a leak-proof structure, comprising a first cylinder and an expansion joint;

[0007] An expansion joint is fixed to the top of the first cylinder, and a second cylinder is fixed to the top of the expansion joint. A separation liquid outlet is fixed to one side of the bottom of the first cylinder, and a gas overflow pipe is fixed to one side of the top of the second cylinder.

[0008] A sealing structure is provided above the second cylinder;

[0009] The second cylinder has a heat exchange structure fixed inside. The heat exchange structure includes a first tube sheet fixed to the bottom of the first cylinder and a second tube sheet fixed to the top of the second cylinder. Heat exchange tubes are uniformly fixed inside the first tube sheet, and baffles are uniformly sleeved on the outside of the heat exchange tubes.

[0010] When using this device, the heat exchange structure facilitates improved heat exchange efficiency, thereby enhancing the applicability of the shrinkage unit during use; the sealing structure prevents leakage, thus improving the sealing performance of the shrinkage unit during use.

[0011] Preferably, the sealing structure includes a head, a gas-liquid mixture inlet, a connecting flange, connecting bolts, a liner, and a gasket. The head is disposed above the second cylinder. The gas-liquid mixture inlet is fixed to the top of the head. The connecting flange is fixed to the outer side of the bottom of the head. A gasket is disposed at the bottom of the connecting flange. Connecting bolts are uniformly inserted through the interior of the connecting flange. A liner is fixed to the bottom of the head.

[0012] Preferably, a first flange is fixed to the outer side of the top of the gas-liquid mixture inlet, and the bottom end of the connecting bolt passes through the interior of the second tube sheet. The connecting bolt fixes or separates the connecting flange and the second tube sheet, and the gasket effectively fills the tiny gap between the connecting flange and the second tube sheet, preventing leakage of the internal gas-liquid mixture.

[0013] Preferably, the connecting bolts are evenly spaced inside the connecting flange, and the connecting flange and the second tube sheet are fixedly connected by the connecting bolts. This also prevents impurities such as outside air from entering, thereby enhancing the sealing performance between the connecting flange and the second tube sheet.

[0014] Preferably, the bottom end of the gasket abuts against the top end of the second tube sheet. The liner provides corrosion and wear protection to the inner wall of the equipment, while also helping to maintain the shape of the internal flow channels and assisting material flow.

[0015] Preferably, a spacer tube is uniformly inserted inside the baffle plate, and a tie rod is inserted inside each spacer tube. A cooling water inlet is fixed to the bottom of the first cylinder on the side away from the separation liquid outlet, and a cooling water outlet is fixed to the top of the second cylinder on the side away from the gas overflow pipe.

[0016] Preferably, the heat exchange tubes are arranged in three sets, and a second flange is fixed to one end of the cooling water outlet and one end of the cooling water inlet, respectively. The top end of the heat exchange tube extends into the interior of the second tube sheet. The second flange facilitates the connection of external cooling water, allowing the cooling water to circulate inside the heat exchange tubes.

[0017] Preferably, the bottom end of the tie rod extends into the interior of the first tube sheet, and one side of the baffle plate at the top of the heat exchange tube is fixedly connected to the inner wall of the second cylinder. Under the action of the spacer tube and the tie rod, the heat exchange tubes are fixed, ensuring uniform spacing between them. This allows the cooling water to be evenly distributed and flow stably within the heat exchange tubes, preventing insufficient local heat exchange. After absorbing heat, the water is discharged from the cooling water outlet.

[0018] Preferably, one side of the baffle plate at the bottom of the heat exchange tube is fixedly connected to the inner wall of the first cylinder, and the baffle plates are staggered on both sides of the interior of the first and second cylinders. Under the action of the baffle plates, the flow direction of the material can be changed, increasing the contact time and contact area between the material and the heat exchange tube, thereby achieving efficient heat exchange.

[0019] Preferably, a third flange is fixed to the end of the separation liquid outlet away from the first cylinder, and a fourth flange is fixed to the end of the gas overflow pipe away from the second cylinder.

[0020] The present invention provides a shrinkage unit with a leak-proof structure, the advantages of which are:

[0021] With a heat exchange structure, the second flange facilitates the connection of external cooling water, allowing the cooling water to circulate inside the heat exchange tubes. The spacer tubes and tie rods fix the heat exchange tubes and ensure uniform spacing, resulting in even distribution and stable flow of cooling water within the tubes. This prevents insufficient localized heat exchange. After absorbing heat, the water is discharged from the cooling water outlet. The baffles change the flow direction of the material, increasing the contact time and area between the material and the heat exchange tubes, thus achieving efficient heat exchange. This device enhances the heat exchange effect and improves the applicability of the distributor.

[0022] By incorporating a sealing structure, the connecting flange and the second tube sheet are fixed or separated by the connecting bolts. The gasket effectively fills the tiny gaps between the connecting flange and the second tube sheet, preventing leakage of the internal gas-liquid mixture and preventing the entry of external air and other impurities, thereby enhancing the sealing performance between the connecting flange and the second tube sheet. The liner provides corrosion and wear protection to the inner wall of the equipment and helps maintain the shape of the internal flow channel, facilitating material flow. This design facilitates leak prevention and improves the sealing performance of the distributor during use. Attached Figure Description
