Description

Technical Field

[0001] The present invention relates to the technical field of concentration and drying, and in particular to an eccentric low-temperature and high-efficiency rotary concentration tank, which is applicable to the field of concentration and drying equipment. Technical Background

[0002] The rotary concentrator is a common type of concentrating and drying equipment, suitable for concentrating materials such as traditional Chinese medicine, Western medicine, starch sugar, and dairy products, as well as recovering industrial organic solvents like alcohol. It is also well-suited for low-temperature vacuum concentration of heat-sensitive materials in small batches and with a wide variety of applications. However, as the drying and concentrating process progresses, the material level within the drum decreases. When the material cannot completely submerge the drum or is below the drum's stirring level, the drum cannot adequately stir the material, resulting in low heat transfer efficiency and prolonged heating time, which can even affect the quality of the final product.

[0003] Based on the above technical defects, the present invention proposes an eccentric low-temperature and high-efficiency rotary concentrator, in which the drum stirring shaft is eccentrically placed with the cylinder, and the center of the drum is located directly below the center of the cylinder. Without affecting the early concentration efficiency, the material at the bottom of the concentration tank can be fully stirred to improve the concentration efficiency. Summary of the Invention

[0004] The present invention proposes an eccentric, low-temperature, and high-efficiency rotary concentrator to address the aforementioned technical issues, namely, the decrease in material volume, reduced concentrator efficiency, and poor heat transfer efficiency as the concentrating process progresses. To achieve this objective, the present invention provides the following technical solution: The eccentric, low-temperature, and high-efficiency rotary concentrator primarily comprises a motor, a reducer, a rotary joint, a bearing chamber, a mechanical seal, a concentrator barrel, a drum agitator shaft, a gas-liquid separator, a temperature transmitter, and support legs. The eccentric, low-temperature, and high-efficiency rotary concentrator pipe primarily comprises a feed inlet, a jacket heat source inlet, a jacket heat source outlet, a sight glass port, a discharge port, a vacuum port, a stirrer shaft heat source inlet, and a stirrer shaft heat source outlet. The motor is connected to the top of the reducer, which is horizontally connected to the mechanical seal via the bearing chamber. The mechanical seal is connected to one side of the concentrator barrel. The gas-liquid separator is flange-mounted at the top of the concentrator barrel. The drum agitator shaft is assembled and connected to the mechanical seal, bearing chamber, reducer, and rotary joint, respectively. The support legs are welded to the bottom of the concentrator barrel and the outer shell of the bearing chamber.

[0005] Furthermore, the end cover of the above-mentioned concentration tank away from the motor is provided with two sight glass openings at the upper and lower ends, which can be used to observe the state of the material in the concentration tank.

[0006] Furthermore, the gas-liquid separator is connected to the top of the concentration tank, and the top of the concentration tank is provided with a feed inlet and a jacket heat source outlet on both sides of the gas-liquid separator.

[0007] Furthermore, a temperature transmitter is provided in the middle of the bottom of the above-mentioned concentration tank, and a jacket heat source inlet and a discharge port are respectively provided on both sides of the temperature transmitter at the bottom of the concentration tank.

[0008] Furthermore, a heat source circulation pipeline is provided inside the above-mentioned drum stirring shaft, and a stirring shaft heat source inlet and a stirring shaft heat source outlet are provided at the rotary joint. The heat source enters the internal pipeline of the drum stirring shaft from the stirring shaft heat source inlet for circulation and flows out from the rotating stirring shaft heat source pipeline outlet.

[0009] Furthermore, the center of the drum stirring shaft is located directly below the center of the cylinder of the concentration tank. The drum stirring shaft can stir the material in the concentration tank to a greater extent, thereby improving the concentration efficiency.

[0010] Compared with the prior art, the present invention has the beneficial effect that, through the eccentric drum stirring shaft structure, the material at the bottom of the concentration tank can be fully stirred without affecting the early concentration efficiency, thereby improving the concentration efficiency.

[0011] (1) The top gas-liquid separator is connected to the vacuum system, which can realize low-temperature concentration of materials under negative pressure conditions and is suitable for the concentration of heat-sensitive materials.

[0012] (2) At the same time, a heat source pipeline is provided inside the drum stirring shaft, and the heat source can be introduced into the stirring process to heat the material, thereby improving the heat transfer efficiency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
