Description

Technical Field

[0001] This utility model relates to the field of veterinary drug processing technology, and in particular to a liquid veterinary drug concentrator. Background Technology

[0002] Concentration is a critical step in the production of liquid veterinary drugs. Many veterinary drug components, such as proteins, polysaccharides, and saponins, are prone to generating a large amount of foam during concentration and heating. This foam not only causes the loss of effective ingredients and reduces the yield, but in severe cases, it can also clog vacuum pipes, leading to production interruption and affecting the stable operation of the entire production line.

[0003] Existing defoaming methods are mainly divided into chemical defoaming and mechanical defoaming. Chemical defoaming requires the addition of defoaming agents, which may introduce foreign impurities and affect product purity and safety. Mechanical defoaming, such as simple stirring or baffles, is not effective for stubborn foam and cannot adapt to the dynamic changes in liquid level during the concentration process, resulting in a decrease in defoaming effect in the later stage of concentration. Utility Model Content

[0004] The purpose of this utility model is to provide a liquid veterinary drug concentrator in order to solve the above-mentioned problems.

[0009] Preferably, the telescopic sleeve consists of a telescopic inner tube and an outer tube, with a cavity between the inner and outer tubes for liquid flow, and a through hole communicating with the cavity is provided on the outer side of the nozzle and connecting cylinder.

[0010] Preferably, a cleaning pipe is also installed at the upper end of the tank. The cleaning pipe consists of an inlet pipe and an annular pipe. The annular pipe is located outside the conical shroud, and multiple nozzles facing the inner wall of the tank are provided at the top and bottom.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 This utility model provides a technical solution: a liquid veterinary drug concentrator, including a tank 1 and a stirring mechanism 2. A circulation mechanism 3 is connected to the outside of the tank 1. The outlet end of the circulation mechanism 3 is connected to an antifoaming mechanism 4 located inside the upper part of the tank 1. The antifoaming mechanism 4 includes a nozzle 401, a conical cover 402, a float 403, and a telescopic sleeve 404. The telescopic sleeve 404 is installed on the outside of the nozzle 401. The conical cover 402 is installed at the bottom of the nozzle 401 and has a gap with the inner wall of the tank 1. The float 403 is attached to the bottom of the conical cover 402. A turbine 10 is rotatably connected inside the nozzle 401. A rotating cylinder 11 is installed at the bottom of the turbine 10. A blade 12 is installed at the lower end of the rotating cylinder 11 extending out of the nozzle 401. Tank 1 consists of an inner tank 101 and an outer tank 102. The tops of the inner tank 101 and the outer tank 102 are fixedly connected by flange structure and bolts and nuts to form a detachable sealed top cover. A discharge pipe 5 connected to the inner tank 101 is installed on the outside of the outer tank 102. A discharge pipe 6 connected to the inner tank 101 is installed at the bottom of the outer tank 102. Valves are installed on both the discharge pipe 5 and the discharge pipe 6. The valves can be manual valves or electric control valves. An air outlet pipe 7 connected to the inner tank 101 is installed on the top of the outer tank 102. There is a gap between the inner tank 101 and the outer tank 102. Two connecting pipes 8 connected to the gap are connected to the outside of the outer tank 102. The top connecting pipe 8 is connected to the inlet pipe of an external circulation device (such as a hot water unit). The bottom connecting pipe 8 is connected to the outlet pipe of an external circulation device (such as a hot water unit). The stirring mechanism 2 includes a motor 201 installed at the bottom of the tank 1. The output end of the motor 201, which extends into the tank 1, is connected to a rotating rod 202. The upper end of the rotating rod 202 passes through the rotating drum 11, the turbine 10, and the nozzle 401 and is rotatably connected to the bottom of the connecting cylinder 405. The middle and lower ends of the rotating rod 202 are both equipped with connecting rods 203. A scraper 204 that fits against the inner wall of the tank 1 is connected between the middle and lower connecting rods 203. The circulation mechanism 3 includes a liquid pump 301 installed on the outside of the tank body 1. The inlet end of the liquid pump 301 is connected to a suction pipe 302 that extends into the lower part of the tank body 1, and the outlet end of the liquid pump 301 is connected to a drain pipe 303. During the concentration operation, the motor 201 is started to drive the scraper 204 to rotate, which prevents coking on the tank wall and promotes heat exchange. At the same time, the liquid pump 301 of the circulation mechanism 3 is started to pump the liquid from the bottom of the tank 1 into the tank through the liquid extraction pipe 302, and then deliver it to the spray pipe 401 of the defoaming mechanism 4 through the drain pipe 303 and the telescopic sleeve 404 and spray it out. During the concentration process, due to the presence of surface-active substances such as proteins and polysaccharides in the liquid, a large amount of stubborn foam will be generated. The freely rising foam will be dispersed across the entire cross-section of the tank 1. The conical cover 402, as a conical physical barrier, can effectively gather and confine the diffused foam within its limited internal cavity, preventing the foam from escaping to the surroundings, thereby creating a high-density target area for subsequent defoaming actions. The high-pressure liquid flow ejected from the nozzle 401 first drives the internal turbine 10 to rotate. The turbine 10 drives the blades 12 at the bottom to rotate at high speed through the rotating cylinder 11. The rotating blades 12 generate strong shearing and impact forces on the foam layer that has been gathered by the conical shroud 402, which can effectively tear and break the stubborn foam liquid film. Its defoaming ability far exceeds that of simple spraying. The liquid sprayed from the nozzle 401 directly wets and impacts the foam, forming the first line of defense against foaming. At the same time, through the buoyancy provided by the float 403, the entire defoaming mechanism 4 can adaptively slide down as the concentrated liquid level drops through the extension and retraction of the telescopic sleeve 404, ensuring that the blades 12 and the nozzle 401 always act on the gas-liquid interface where the foam is most concentrated, thus achieving efficient defoaming throughout the entire process.

[0017] Specifically, such as Figure 4 and Figure 5 As shown, the upper end of the telescopic sleeve 404 is connected to the connecting cylinder 405, and the top of the connecting cylinder 405 is equipped with a connecting seat 406 that is threaded to the outlet end of the drain pipe 303. The connecting cylinder 405 is a hollow cylindrical component, and its interior forms a transition channel for the liquid to flow from the drain pipe 303 to the telescopic sleeve 404. The connecting seat 406 is designed to realize the detachable connection between the drain pipe 303 and the entire defoaming mechanism 4.

[0018] Specifically, such as Figure 5 As shown, the telescopic sleeve 404 consists of a telescopic inner tube 4041 and an outer tube 4042. A cavity for liquid flow is provided between the inner tube 4041 and the outer tube 4042. A through hole communicating with the cavity is opened on the outer side of the nozzle 401 and the connecting cylinder 405. The inner tube 4041 and the outer tube 4042 are located on the outer side of the rotating rod 202. The primary function of the design of the telescopic sleeve 404 is to provide support and fluid channel for the up and down sliding of the entire defoaming mechanism 4, while ensuring that the independent rotation of the central rotating rod 202 is not affected.

[0019] Specifically, such as Figure 2 As shown, a cleaning pipe 9 is also installed at the upper end of the tank 1. The cleaning pipe 9 consists of an inlet pipe 901 and an annular pipe 902. The annular pipe 902 is located outside the conical cover 402, and multiple nozzles 903 facing the inner wall of the tank 1 are provided at the top and bottom. Since the conical cover 402 covers the outside of the nozzle 401, the method of adding cleaning liquid into the inner tank 101 and then circulating it through the circulation mechanism 3 may be blocked by the conical cover 402, resulting in the inability to spray the upper part of the inner tank 101. Therefore, an independent cleaning pipe 9 is set up separately to effectively clean the inner wall and top of the inner tank 101 and other areas covered by the conical cover 402 when the defoaming mechanism 4 is in place, ensuring that there are no dead corners in the cleaning.

[0020] In summary, the specific working process of the liquid veterinary drug concentrator provided in this embodiment is as follows: First, the concentrated medicine liquid is poured into the inner tank 101 through the discharge pipe 5. Then, the motor 201 is started to drive the rotating rod 202 and the scraper 204 installed on it to rotate, continuously stirring the medicine liquid and scraping off the deposits on the wall of the inner tank 101 to prevent coking and promote heat exchange. At the same time, the external circulation device introduces a heat medium, such as hot water, into the jacket gap between the inner tank 101 and the outer tank 102 through the connecting pipe 8 to heat the medicine liquid in the tank evenly and gently. During concentration, the vent pipe 7 is connected to a vacuum pump to reduce the pressure inside the tank to the set vacuum level. Under the combined action of low pressure and heating, the boiling point of the liquid decreases and it begins to evaporate violently. The water vapor generated by evaporation is extracted through the vent pipe 7. At the same time, surface-active substances such as proteins and polysaccharides in the liquid generate a large amount of stubborn foam in the boiling state, which rises upward with the steam. The rising foam is first captured by the conical cover 402 and gathered in the limited cavity inside it, which prevents the foam from spreading over a large area inside the tank. The float 403 floats on the liquid surface. As the concentration proceeds and the liquid level drops, the float 403 drives the entire defoaming mechanism 4 to slide down adaptively along the rotating rod 202 through the extension and retraction of the telescopic sleeve 404, ensuring that the defoaming action always accurately acts on the gas-liquid interface where the foam is most concentrated. The liquid pump 301 of the circulation mechanism 3 is started, and the liquid medicine in the lower part of the tank 1 is pumped in through the liquid extraction pipe 302. It is then transported to the nozzle 401 through the liquid discharge pipe 303 and the telescopic sleeve 404. Before the high-pressure liquid flow is sprayed out from the nozzle 401, it first impacts the axial impact turbine 10 inside, driving the turbine 10 to rotate. The turbine 10 drives the blades 12 at the bottom to rotate at high speed through the rotating cylinder 11. The rotating blades 12 generate strong shearing and impact forces on the foam layer that has been gathered by the conical cover 402, which can efficiently tear and break the stubborn foam liquid film. The liquid sprayed from nozzle 401 directly wets and impacts the foam, forming the first line of defense against defoaming, and complementing the subsequent mechanical shearing. After production is completed, in order to thoroughly clean the equipment, the inlet pipe 901 can be connected to an external cleaning tank containing cleaning fluid. The cleaning fluid can then be sprayed onto the inner wall of the inner tank 101 and the area covered by the conical cover 402 through the annular pipe 902 and the nozzle 903 of the cleaning pipe 9.
