Description

Technical Field

[0001] The utility model relates to the technical field of single-effect evaporators, in particular to a single-effect evaporator with a hierarchical heating function. Background Technique

[0002] A single-effect evaporator is a device used for evaporating and concentrating solutions. By heating, the solvent in the solution is vaporized, thereby increasing the concentration of the solute in the solution. Generally, it consists of an evaporator main body, a heating chamber, a separation chamber, a condenser, a vacuum pump and other parts. The single-effect evaporator has the advantages of relatively simple structure and convenient operation. However, it also has some limitations such as relatively low energy utilization rate.

[0003] The existing Chinese patent with the publication number CN217988370U provides a single-effect evaporator, which includes a heater, an evaporation tank and a gas-liquid separator. The raw material to be processed is fed into the heater from the heater feed port for heating, and at the same time, steam is introduced into the heater from the steam inlet. The raw material is heated in the heater, and the water in the raw material is vaporized to form the evaporation liquid to be extracted, solving the problems of poor evaporation effect of the single-effect evaporator and large heat loss during the evaporation process, which is likely to increase the evaporation cost.

[0004] Aiming at the above-mentioned related technologies, the problem is that the conventional single-effect evaporator uses a single heat source and cannot provide heat for different materials, resulting in energy waste. Content of the Utility Model

[0005] The purpose of the utility model is to provide a single-effect evaporator with a hierarchical heating function. By using this device for work, the problem that the conventional single-effect evaporator uses a single heat source and cannot provide heat for different materials, resulting in energy waste, is solved.

The rotation of the bevel gear drives the transmission member to rotate, causing the guide pipe to rotate, and thus driving the conical tube to rotate. While the heating ring heats the materials on the inner wall of the conical tube, the materials on the conical tube rotate together, making the preheating of the materials on the inner wall of the conical tube more sufficient. Subsequently, the materials fall from the output end of the conical tube into the guide pipe and enter the bottom of the tank for further heating operation.

[0009] The motor drives the connecting ring to rotate, thereby driving the guide pipe to rotate and causing the overall rotation of the preheating assembly.

[0010] Preferably, a plurality of annular protrusions are provided on the inner wall of the conical tube.

[0011] The annular protrusions block the falling of the materials, increasing the heating time of the heating ring for the materials and making the preheating of the materials more sufficient.

[0012] Preferably, a tapered sleeve is sleeved outside the guide pipe, the lower end of the tapered sleeve is fixedly connected to the inner wall of the tank, the tapered sleeve is located below the transmission member, and a heating plate is installed at the bottom of the inner wall of the tank.

[0013] The materials in the guide pipe fall to the bottom of the inner wall of the tank, and the heating plate heats the materials until the moisture contained in the materials evaporates into water vapor.

[0014] Preferably, an air outlet pipe is installed through the tank body, one end of the air outlet pipe located inside the tank body is connected through the tapered sleeve, and a fan is installed on the air outlet pipe.

[0015] The moisture in the materials is evaporated into water vapor and gathers inside the tapered sleeve. Start the fan to extract the gathered water vapor out of the tank body along the air outlet pipe.

[0016] Preferably, a liquid outlet pipe is installed through the tank body on one side close to the heating plate.

[0017] After heating is completed, the high-concentration materials that have completed the evaporation operation are exported from the tank body through the liquid outlet pipe.
