Description

Technical Field

[0001] The invention relates to the technical field related to evaporation concentrators, and in particular to a heat pump low-temperature evaporation concentrator with a cleaning structure. Background Art

[0002] A heat pump is a highly efficient energy-saving device that fully utilizes low-grade thermal energy. Heat can be transferred spontaneously from a high-temperature object to a low-temperature object, but not spontaneously in the opposite direction. The working principle of a heat pump is a mechanical device that forces heat from a low-temperature object to a high-temperature object in a reverse cycle. It consumes only a small amount of reverse cycle net work to obtain a large amount of heat supply, and can effectively utilize low-grade thermal energy that is difficult to apply to achieve energy-saving purposes. An evaporation concentrator reduces the moisture content in items by evaporation, thereby reducing the quality of the items and concentrating the items, making it easier to package and transport and reducing transportation costs. Its principle is to reduce the vacuum environment of the item so as to reduce the boiling point of the item itself, thereby achieving concentration without destroying the original structure of the item. A heat pump low-temperature evaporation concentrator is now needed for evaporation and concentration processing;

[0003] For example, the utility model patent application with the authorization publication number CN214714396U discloses a low-temperature vacuum evaporation concentrator, including an evaporation concentrator body, the evaporation concentrator body including a main box, a first cavity and a third cavity are provided on both sides of the internal width direction of the main box, a second cavity is provided inside the main box between the first cavity and the third cavity, a partition is provided between the first cavity and the second cavity and between the second cavity and the third cavity, a vacuum machine is provided on the inner side of the first cavity, a reaction cylinder is provided on the inner side of the second cavity, and an exhaust fan for steam extraction is provided on the inner side of the third cavity on the side section of the partition away from the second cavity, and the device can reduce the boiling point temperature by vacuuming through the provided vacuum machine;

[0004] For example, the utility model patent application with the authorization publication number CN215939024U discloses a low-temperature vacuum evaporation concentrator, including a tank body, a base and a vacuum tube, an evaporation water tank is installed on one side of the top of the base, a tank body is vertically installed on the top of the base on one side of the evaporation water tank, and an evaporation tube is laid in a ring on the inner wall of the tank body, a discharge port is provided at the middle position of the bottom end of the tank body, a circulation pump is installed on the top of the base on one side of the tank body, a return pipe extending to the upper end of one side of the tank body is installed at the output end of the circulation pump through a conduit, and a discharge pipe is installed at the lower end of one side of the return pipe, a vacuum tube is vertically provided on one side of the top of the tank body, and a feed pipe is installed at the upper end of the other side of the tank body. The utility model avoids filtering and adsorbing the water vapor generated by the boiling of the material by setting an adsorption chamber and a filtration chamber, and avoids a small amount of material contained therein adhering to the internal pipe of the condenser, causing the pipe to be blocked, and affecting the subsequent normal operation of the concentrator;

[0005] For example, the utility model patent application with the authorization publication number CN204865021U discloses a low-temperature vacuum concentrator using heat pump technology, which uses vacuum technology to reduce the boiling point of the material so that the evaporation temperature of the material reaches 22-25"C. The heat pump unit is used to provide heat source and cold source for the concentrator, so as to achieve the purpose of improving efficiency, reducing energy consumption and saving space. The utility model includes a material evaporation tank 7, the lower port of the material evaporation tank 7 is connected to one end of the material raw liquid inlet valve 16 and the first end of the second pipeline three-way joint 13 through a first pipeline three-way joint 17, and the other end of the material raw liquid inlet valve 16 is connected to the outlet of the material raw liquid storage tank 10; the pipeline of the material nozzle 6 in the material evaporation tank 7 is connected to the outlet of the material heating heat exchanger 9 through the upper end cover of the material evaporation tank 7.

[0006] However, the commonly used heat pump low-temperature evaporation concentrator with a cleaning structure still has the following shortcomings:

[0007] 1. In the existing heat pump low-temperature evaporation concentrator with a cleaning structure, due to the different liquids being concentrated and evaporated inside the concentrator body, stains will remain inside the concentrator body after a long period of accumulation, and solid matter will also have residues inside the concentrator body, which will cause odor or bacteria inside the concentrator body, affecting the materials that need to be evaporated and concentrated, and it is not convenient to clean the inside of the concentrator body;

[0008] 2. The existing heat pump low-temperature evaporation concentrator with a cleaning structure has a separate storage basket for placing the materials to be evaporated and concentrated. The storage basket is generally in direct contact with the materials to be evaporated and concentrated, and there will be residues adhering to the storage basket. If the storage basket cannot be disassembled, it is not convenient to disassemble the storage basket for cleaning, and it is not convenient to unload the materials inside the storage basket;

[0009] 3. In the existing heat pump low-temperature evaporation concentrator with a cleaning structure, the liquid compressed by vacuum is stored inside the liquid storage box and subjected to heat pump evaporation treatment. The liquid will be accompanied by odor or residue, which will remain inside the liquid storage box. Over time, stubborn stains or odors will accumulate and affect the low-temperature evaporation concentrator. It is inconvenient to separate the liquid storage box and clean the inside of the liquid storage box.
