Description

Technical Field

[0001] This utility model belongs to the technical field of chondroitin sulfate production and processing equipment, and in particular a concentration device. Background Technology

[0002] Chondroitin sulfate is an acidic mucopolysaccharide extracted and purified from animal cartilage tissue. It possesses various important physiological functions and applications. In the production of chondroitin sulfate, the extract needs to be concentrated to increase its concentration, facilitating subsequent drying and purification processes. The chondroitin sulfate solution itself contains multiple components, including chondroitin sulfate macromolecules, proteins, and polysaccharides. These macromolecules and surfactants are prone to foaming during concentration due to the presence of the gas-liquid interface. Existing concentration equipment can meet basic concentration requirements, but its defoaming ability is weak, leading to reduced evaporation efficiency and decreased product quality.

[0003] A search revealed a Chinese patent document (authorization announcement number CN116370980A), which discloses a high-efficiency concentration device for chondroitin sulfate. The device includes a heating tank with an annular cover at the top, a main concentration tank inside the heating tank with a lid at the top, an inlet pipe on the outside of the heating tank, a discharge pipe at the bottom of the inlet pipe, a hollow column inside the heating tank, a heating assembly on the outside of the heating tank, a water supply assembly at the top of the heating assembly, a stirring assembly at the top of the main concentration tank, a monitoring assembly on the outside of the heating tank, a drainage pipe assembly on the outside of the monitoring assembly, an exhaust assembly on the outside of the heating tank, a filter assembly at the top of the exhaust assembly, an exhaust pipe on the outside of the main concentration tank, and a water outlet pipe on the outside of the heating assembly. This high-efficiency concentration device for chondroitin sulfate can efficiently concentrate chondroitin sulfate solution while simultaneously detecting its concentration and content. While this device meets basic concentration requirements, its weak defoaming ability leads to reduced evaporation efficiency and decreased product quality. Utility Model Content

[0004] The purpose of this invention is to provide a concentration device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concentration device, comprising a protective shell for preventing heat leakage during chondroitin sulfate concentration, a concentration tank for chondroitin sulfate concentration is disposed inside the protective shell, a crossbar is connected to the top of the concentration tank, a cover plate is installed on the side of the crossbar, a first motor is installed on the top of the cover plate, the output shaft of the first motor is connected to a rotating shaft through a coupling, a connecting column and a blade are installed on the outer periphery of the rotating shaft, two defoaming blocks are symmetrically welded to the outer periphery of the connecting column, corrugated grooves are provided on the sides of the two defoaming blocks, springs are connected to the sides of the two defoaming blocks, and a defoaming plate is connected to the end of the spring away from the defoaming block.

[0006] Preferably, a support is welded to the bottom of the concentration tank, and a second motor is installed at one end of the support. The output shaft of the second motor is connected to a gear through a coupling.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This concentration device benefits from the structure of the foam-breaking block and the foam-breaking plate. When the foam-breaking block rotates, it causes the foam-breaking plate to come into contact with the foam. The corrugated grooves disturb the airflow in the upper layer of the concentration tank, accelerating the foam breakage. The foam-breaking plate breaks upon contact with the foam, and some of the airflow generated by the breakage acts on the surface of the foam-breaking plate. Due to the action of the spring, the foam-breaking plate vibrates in multiple directions, accelerating the foam breakage and improving the foam-breaking efficiency. Compared with the weak foam-breaking ability of traditional concentration devices, this structure can improve the foam-breaking efficiency, increase the evaporation efficiency, and improve the product quality.

[0014] This concentration device benefits from the structure of the rotary heating tube. The second motor drives the gear to rotate, and the gear drives the gear plate and support plate to rotate along the inner wall of the protective shell. The rotary heating tube rotates along the outer wall of the concentration tank. Since the rotary heating tube is spiral, it can evenly heat the chondroitin sulfate solution in the concentration tank.

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0024] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0025] like Figures 1 to 5 The illustrated concentration device includes a protective shell 1 to prevent heat leakage during chondroitin sulfate concentration. Inside the protective shell 1 is a concentration tank 2 for chondroitin sulfate concentration. The concentration tank 2 has good thermal conductivity to ensure that heat is effectively transferred to the chondroitin sulfate solution, achieving efficient evaporation. A crossbar 202 is connected to the top of the concentration tank 2. A cover plate 201 is installed on the side of the crossbar 202. A first motor 203 is installed on the top of the cover plate 201. The output shaft of the first motor 203 is connected to a rotating shaft 204 via a coupling. A connecting column 205 and a paddle 206 are installed on the outer periphery of the rotating shaft 204. Two defoaming blocks 3 are symmetrically welded to the outer periphery of the connecting column 205. Corrugated grooves 301 are provided on the sides of both defoaming blocks 3. Springs 302 are connected to the sides of both defoaming blocks 3. A defoaming plate 303 is connected to the end of the spring 302 away from the defoaming block 3. The first motor 203 is then turned on. The first motor 203 drives the rotating shaft 204, connecting column 205 and blade 206 to rotate. The blade 206 agitates the chondroitin sulfate solution in the concentration tank 2. When the concentration of the chondroitin sulfate solution increases, foam will be generated. When the defoaming block 3 rotates, it drives the defoaming plate 303 to contact the foam. The corrugated groove 301 disturbs the airflow in the upper layer of the concentration tank 2, accelerating the foam to break. The defoaming plate 303 breaks upon contact with the foam. Part of the airflow generated by the break will act on the surface of the defoaming plate 303. Due to the action of the spring 302, the defoaming plate 303 vibrates in multiple directions, accelerating the foam to break and improving the defoaming efficiency.

[0026] A support 402 is welded to the bottom of the concentration tank 2. A second motor 4 is installed at one end of the support 402. The output shaft of the second motor 4 is connected to a gear 401 through a coupling. A gear 404 is meshed with the outer circumference of the gear 401. A turntable 403 is installed on the side of the gear 404. A rotary heating tube 405 for heating is installed on the top of the turntable 403. When the second motor 4 is turned on, the second motor 4 drives the gear 401 to rotate. The gear 401 drives the gear 404 and the support plate 406 to rotate along the inner wall of the protective shell 1. The rotary heating tube 405 rotates along the outer wall of the concentration tank 2. Since the rotary heating tube 405 is spiral, it can evenly heat the chondroitin sulfate solution in the concentration tank 2.

[0027] A support plate 406 is welded to the vertical inner wall of the protective shell 1. A base 101 is installed at the bottom of the protective shell 1. A top cover 102 is installed at the top of the protective shell 1. The top of the cover plate 201 is connected to an exhaust pipe 103 for steam discharge. The water in the chondroitin sulfate solution turns into water vapor and is discharged from the exhaust pipe 103.

[0028] The bottom of the concentration tank 2 is connected to the discharge port 5. The discharge port 5 is equipped with a control valve 501 for controlling the discharge of concentrated chondroitin sulfate. The inner bottom wall of the protective shell 1 is provided with a collection tank 106. After concentration, the control valve 501 can be opened, and the concentrated chondroitin sulfate enters the collection tank 106 from the discharge port 5 for collection. The outer periphery of the protective shell 1 is equipped with a temperature display tube 105, which can monitor the temperature of the concentration tank 2. The temperature can be adjusted in time by observing the temperature of the temperature display tube 105. The top of the protective shell 1 and the cover plate 201 are both provided with a feed port 104. The feed port 104 is opened, and the chondroitin sulfate to be concentrated is added into the concentration tank 2 through the feed port 104. The feed port 104 can be closed by a sealing plate to ensure the airtightness during concentration.

[0029] Chondroitin sulfate solution is typically acidic and contains sulfate ions, requiring the materials used in the concentration unit to withstand corrosion in acidic environments. For example, stainless steel, especially 316L stainless steel, is commonly used. It contains molybdenum, which enhances its corrosion resistance in highly corrosive environments such as those with chloride ions. Components like the first motor (203) and the second motor (4) are designed for high-temperature operation; high-temperature motors are those capable of continuous and stable operation in high-temperature environments. The chondroitin sulfate concentration unit operates in a high-temperature environment. If the motors are not heat-resistant, performance degradation, shortened lifespan, or even damage may occur, affecting the normal operation of the entire concentration unit. The ambient temperature of these motors may rise due to heat radiation and steam leakage, sometimes exceeding 100°C. Furthermore, sealing performance is crucial for the concentration unit. Connections between materials, such as flange connections in pipes and connections between pumps and pipes, require sealing materials to prevent solution leakage. For example, rubber sealing rings are used, and the materials must be compatible with other components of the concentration unit, maintaining good sealing performance under different temperature, pressure, and chemical environments.

[0030] Working principle

[0031] In operation, the concentration device is first opened through the inlet 104, and the chondroitin sulfate to be concentrated is added into the concentration tank 2. The rotating heating tube 405 heats the solution, and the first motor 203 is turned on. The first motor 203 drives the rotating shaft 204, connecting column 205, and impeller 206 to rotate. The impeller 206 agitates the chondroitin sulfate solution in the concentration tank 2, accelerating the conversion of water in the chondroitin sulfate solution into water vapor, which is then discharged from the outlet pipe 103. As the concentration of the chondroitin sulfate solution increases, foam is generated. When the foam-breaking block 3 rotates, it causes the foam-breaking plate 303 to come into contact with the foam. The corrugated groove 301 disrupts the airflow in the upper layer of the concentration tank 2, accelerating the foam breakage. 03 When the foam comes into contact with the foam, it breaks. Part of the airflow generated by the breakage will act on the surface of the foam breaking plate 303. Due to the action of the spring 302, the foam breaking plate 303 will vibrate in multiple directions, accelerating the foam breaking and improving the foam breaking efficiency. The second motor 4 is turned on, and the second motor 4 drives the gear 401 to rotate. The gear 401 drives the gear plate 404 and the support plate 406 to rotate along the inner wall of the protective shell 1. The rotating heating tube 405 rotates along the outer wall of the concentration tank 2. Since the rotating heating tube 405 is spiral, it can evenly heat the chondroitin sulfate solution in the concentration tank 2. After the concentration is completed, the control valve 501 can be opened, and the concentrated chondroitin sulfate enters the collection tank 106 from the discharge port 5 for collection.
