Description

Technical Field

[0001] This utility model belongs to the field of evaporator technology, and in particular relates to an anti-crystallization stirring structure for evaporators. Background Technology

[0002] An evaporator is a heat exchange device used to convert liquids into gases. It plays a key role in many fields. Its working principle is based on thermodynamic laws and the principle of phase change of matter. It provides heat so that the liquid absorbs energy and evaporates into gas, thus realizing the phase change process.

[0003] When using an evaporator to evaporate liquids, heating causes the solvent to evaporate, leading to an increase in the solute concentration in the solution. When this concentration exceeds the solubility limit, crystals precipitate and deposit on the inner wall. This crystallized layer increases thermal resistance, reduces evaporator efficiency, and increases energy consumption. To prevent crystal formation on the inner wall of the evaporator, a stirring scraper is used to clean it. However, the existing scraper structure of evaporators is always in contact with the inner wall, resulting in rapid material wear, shortening the scraper's lifespan, and increasing replacement frequency and costs. Utility Model Content

[0005] This utility model is implemented as follows: an evaporator anti-crystallization stirring structure includes an evaporator and a stirring mechanism. The evaporator includes a cylinder, a heating jacket, and a separation cylinder. The interior of the heating jacket is fixedly connected to the surface of the cylinder, and the bottom of the separation cylinder is fixedly connected to the top of the cylinder. The stirring mechanism includes a stirring rod, a fixed rod, multiple fixed seats, multiple connecting cylinders, and multiple scrapers. The top of the surface of the stirring rod is movably connected to the top of the interior of the separation cylinder, and the bottom of the fixed rod is fixedly connected to the bottom of the interior of the stirring rod.

[0008] In order to enable multiple scrapers to detach from the inner wall of the cylinder, preferably, each of the multiple fixed seats is fixedly connected to a return spring, and the side of each of the multiple return springs near the multiple connecting cylinders is fixedly connected to the inside of the multiple connecting cylinders. The top of the separating cylinder is fixedly connected to a mounting bracket, and the bottom of the mounting bracket is provided with a transmission component. The return springs drive the multiple connecting cylinders to converge inward, so that the multiple scrapers move away from the inner wall of the cylinder.

[0009] To drive the stirring rod to rotate, preferably, the transmission assembly includes a transmission motor, a transmission gear, and a connecting gear ring. The top of the transmission motor is fixedly connected to the right side of the bottom of the mounting bracket, the top of the transmission gear is fixedly connected to the bottom of the output end of the transmission motor, the inside of the connecting gear ring is fixedly connected to the top of the surface of the stirring rod, and the surface of the connecting gear ring meshes with the surface of the transmission gear.

By pressing the pressing cylinder downwards, the pressing cylinder moves downwards and the multiple pressing blocks press the multiple connecting cylinders, causing the multiple connecting cylinders to move outwards, thereby ensuring that the multiple scrapers are in close contact with the inner wall of the cylinder.

[0011] In order to move the lower pressure cylinder downward, preferably, a hydraulic cylinder is fixedly connected to the top of the mounting frame, and a lower pressure rod is fixedly connected to the bottom of the output end of the hydraulic cylinder. The surface of the lower pressure rod is movably connected to the inside of the stirring rod, and the bottom of the lower pressure rod is movably connected to the top of the lower pressure cylinder.

Slide rods are fixedly connected to the front and rear sides inside the mounting frame, respectively. The surfaces of the two slide rods are movably connected to the front and rear sides inside the connecting plate, respectively.

During the rotation of the stirring rod 201, multiple scrapers 205 are moved, and the liquid is stirred by the scrapers 205. When it is necessary to clean the inner wall of the cylinder 101, the hydraulic cylinder 8 is started, and the output end of the hydraulic cylinder 8 drives the lower pressure block 7 to move downward. During the movement of the lower pressure block 7, the lower pressure cylinder 6 is squeezed downward. During the downward movement of the lower pressure cylinder 6, multiple lower pressure blocks 7 squeeze multiple connecting cylinders 204, causing the multiple connecting cylinders 204 to move outward, so that the multiple scrapers 205 are in close contact with the inner wall of the cylinder 101. The inner wall of the cylinder 101 is cleaned by the multiple scrapers 205, preventing the liquid from evaporating and condensing on the inner wall of the cylinder 101.
