Description

Technical Field

[0001] This utility model belongs to the field of evaporation and concentration technology, specifically relating to a low-temperature heat pump evaporator structure. Background Technology

[0002] With the development of industrial energy conservation and environmental protection technologies, in the application of low-temperature heat pump evaporation systems, it is necessary to carry out efficient and stable evaporation and concentration treatment of heat-sensitive materials, which requires the use of evaporator structures.

[0003] In practical use, evaporator structures with similar structures still have many defects. For example, traditional evaporator structures usually use external heating or single heating methods, which have problems such as large heat loss and uneven heating. This can easily lead to local overheating, causing material degradation or scaling. At the same time, in the long-term operation of traditional evaporator structures, the heat transfer surface is prone to the accumulation of dirt, which leads to a decrease in heat transfer efficiency and requires frequent shutdowns for cleaning, affecting production efficiency. Therefore, it is necessary to design a low-temperature heat pump evaporator structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a structure for a low-temperature heat pump evaporator.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a low-temperature heat pump evaporator structure, including a reaction assembly, the reaction assembly including a support frame, a reaction vessel fixedly connected to the top of the support frame, a sealing cover threadedly connected to the outer surface of the reaction vessel, a raw material inlet and a concentrated liquid outlet sequentially opened on the top of the sealing cover, and a steam outlet opened at the bottom of the reaction vessel, and further including: a heating assembly, the heating assembly including a heating tube fixedly connected to the bottom of the sealing cover; and a cleaning assembly, the cleaning assembly including a servo motor fixedly connected to the top of the sealing cover by fixing bolts, the output end of the servo motor being fixedly connected to a cleaning rod and a stirring rod.

[0006] In some embodiments, a control module is fixedly connected to the top of the sealing cover. The control module consists of a control switch and a power module. The power module converts the input electrical energy into a stable voltage and current, ensuring uniform heating of the resistance wire inside the heating tube and avoiding uneven heating or equipment damage caused by voltage fluctuations.

[0007] In some embodiments, a heating tube is fixedly connected to the output terminal of the power module, and the heating tube is located inside the reaction vessel. The heating tube is directly immersed in the raw liquid, and Joule heat is directly transferred to the liquid through the vessel wall, reducing heat loss and improving thermal efficiency.

[0008] In some embodiments, a fixing plate is threadedly connected to the top of the sealing cover via fixing bolts, and a servo motor is fixedly connected to the top of the fixing plate. The fixing plate is connected to the sealing cover via fixing bolts, which enhances the stability of the servo motor installation and avoids loosening or displacement caused by vibration or external force.

[0009] In some embodiments, the output end of the servo motor is fixedly connected to a drive rod through the reactor, and a cleaning rod is fixedly connected to the top of the outer surface of the drive rod. The servo motor drives the drive rod to rotate, which in turn drives the cleaning rod to rotate synchronously, periodically scraping the outer surface of the heating tube, effectively preventing dirt deposition and maintaining the cleanliness of the heat transfer surface.

[0010] In some embodiments, stirring rods are uniformly arranged on the outer surface of the drive rod with the drive rod as the center, and the number of stirring rods is three. The three stirring rods are evenly distributed, which optimizes the hydrodynamic performance, ensures that the raw liquid forms a uniform turbulence in the reaction vessel, and avoids the generation of dead zones or eddies.

[0011] In some embodiments, the cleaning rod is disposed on the outer surface of the heating tube, and three cleaning rods are evenly arranged on the outer surface of the drive rod with the drive rod as the center. The three cleaning rods are evenly distributed, fully covering the outer surface of the heating tube, ensuring thorough and consistent cleaning.

[0012] The scope of this utility model is not limited to technical solutions formed by specific combinations of the above-mentioned technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-mentioned technical features or their equivalent features. For example, technical solutions formed by substituting the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.

[0013] Due to the application of the above technical solutions, this utility model has the following advantages compared with the prior art: This utility model achieves precise control of the heating tube circuit on and off through the control module in the heating assembly, and the structure of the power module converting electrical energy into stable voltage and current to drive the internal resistance wire of the heating tube to heat up, thereby causing the heating tube to generate Joule heat. This heat is evenly transferred to the liquid through the reactor wall, achieving a significant improvement in thermal efficiency. At the same time, the precise temperature adjustment through the control module prevents the problem of material degradation or scaling caused by local overheating, ensuring the uniformity and stability of the liquid heating in the reactor, which is conducive to the smooth progress of the evaporation process.

[0014] This invention utilizes a servo motor-driven drive rod in the cleaning assembly to rotate, which in turn drives the stirring rod to forcefully turbulent the raw liquid. Simultaneously, the cleaning rod rotates synchronously around the drive rod, scraping the outer surface of the heating tube. This forced turbulence of the raw liquid ensures uniform heat distribution and accelerates evaporation. The periodic scraping of the heating tube's outer surface prevents dirt accumulation, thus improving heat transfer efficiency and reducing downtime for maintenance. The three evenly distributed stirring rods optimize fluid dynamics, avoiding dead zones or eddies, while the elastic contact design of the cleaning rod accommodates the thermal expansion of the heating tube, preventing mechanical wear and ensuring the efficient and stable operation of the reactor.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: As shown in the attached document Figure 1-5This embodiment of a low-temperature heat pump evaporator structure includes a reaction assembly 1, which includes a support frame 101. A reaction vessel 102 is fixedly connected to the top of the support frame 101. A sealing cover 103 is threadedly connected to the outer surface of the reaction vessel 102. A raw material inlet 104 and a concentrated liquid outlet 105 are sequentially opened on the top of the sealing cover 103. A steam outlet 106 is opened at the bottom of the reaction vessel 102. The evaporator also includes a heating assembly 2, which includes a heating tube 202 fixedly connected to the bottom of the sealing cover 103. A cleaning assembly 3 includes a servo motor 303 fixedly connected to the top of the sealing cover 103 by a fixing bolt 301. A cleaning rod 305 and a stirring rod 306 are fixedly connected to the output end of the servo motor 303.

[0023] A control module 201 is fixedly connected to the top of the sealing cover 103. The control module 201 consists of a control switch and a power supply module.

[0024] The output end of the power module is fixedly connected to a heating tube 202, which is located inside the reactor 102.

[0025] After power is applied, the circuit of the heating tube 202 can be controlled by adjusting the switch. The power module converts the input electrical energy into a stable voltage and current, which drives the resistance wire inside the heating tube 202 to heat up. Since the heating tube 202 is directly immersed in the raw liquid, the Joule heat it generates is transferred to the liquid through the vessel wall, forming a uniform heating environment and significantly improving thermal efficiency.

[0026] The top of the sealing cover 103 is threadedly connected to a fixing plate 302 via a fixing bolt 301, and a servo motor 303 is fixedly connected to the top of the fixing plate 302.

[0027] The output end of the servo motor 303 is fixedly connected to the drive rod 304 through the reactor 102, and a cleaning rod 305 is fixedly connected to the top of the outer surface of the drive rod 304.

[0028] Three stirring rods 306 are evenly arranged on the outer surface of the drive rod 304 with the drive rod 304 as the center.

[0029] Cleaning rods 305 are disposed on the outer surface of heating tube 202. Cleaning rods 305 are evenly disposed on the outer surface of drive rod 304 with drive rod 304 as the center. The number of cleaning rods 305 is three.

[0030] The three stirring rods 306, which are evenly distributed on the outer surface of the drive rod 304, rotate accordingly to force the liquid to turbulently flow, ensuring uniform heat distribution and accelerating evaporation. At the same time, the cleaning rod 305 rotates synchronously around the drive rod 304, periodically scraping the outer surface of the heating tube 202 to prevent dirt from accumulating. This not only improves heat transfer efficiency but also reduces the frequency of downtime maintenance.

[0031] The implementation principle of a low-temperature heat pump evaporator structure in this application embodiment is as follows: After the raw liquid is injected into the reaction vessel 102 through the raw liquid inlet 104, the operator starts the control module 201. This module consists of a control switch and a power module. After power is turned on, the circuit of the heating tube 202 can be controlled by adjusting the switch. The power module converts the input electrical energy into a stable voltage and current, which drives the resistance wire inside the heating tube 202 to heat up. Since the heating tube 202 is directly immersed in the raw liquid, the Joule heat generated by it is transferred to the liquid through the vessel wall, forming a uniform heating environment, which significantly improves the thermal efficiency. At the same time, the control module 201 realizes precise temperature adjustment to prevent local overheating from causing material degradation or scaling.

[0032] During the heating process, the servo motor 303 is fixed to the top of the sealing cover 103 by the fixing bolt 301, driving the drive rod 304 to rotate. The three stirring rods 306 evenly distributed on the outer surface of the drive rod 304 rotate accordingly, forcibly turbulent the original liquid, ensuring uniform heat distribution and accelerating evaporation. At the same time, the cleaning rod 305 rotates synchronously around the drive rod 304, periodically scraping the outer surface of the heating tube 202 to prevent dirt deposition. This not only improves heat transfer efficiency but also reduces the frequency of downtime maintenance. The three sets of evenly distributed stirring rods 306 further optimize the fluid dynamics performance and avoid dead zones or eddies. The elastic contact design of the cleaning rod 305 can adapt to the thermal expansion of the heating tube 202 and avoid mechanical wear.

[0033] The steam outlet 106 at the bottom of the reactor 102 is used to output the secondary steam generated by evaporation. This steam can be connected to the condenser of the low-temperature heat pump system for heat recovery. The concentrate outlet 105 is used to discharge the residual liquid after treatment, so as to realize continuous production. In the whole process, the synergistic effect of the heating component 2 and the cleaning component 3 ensures the efficient operation of the reactor 102. The heating tube 202 provides a stable heat source, the stirring rod 306 promotes homogenization, and the cleaning rod 305 keeps the heat transfer surface clean.

[0034] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
