Description

Technical Field

[0001] This utility model relates to the field of evaporation device technology, specifically a triple-effect evaporation device. Background Technology

[0002] An evaporator is a device used to convert liquid into vapor through heating, and it is widely used in industries such as chemical, food, and pharmaceutical. Its core principle is to use thermal energy to evaporate and separate the solvent (such as water) in a solution, thereby concentrating or recovering the solute. Common types include natural circulation evaporators, forced circulation evaporators, falling film evaporators, and multi-effect evaporators. The device typically consists of components such as a heating chamber, evaporation chamber, condenser, and separator, and features high efficiency, energy saving, and automated control.

[0003] For example, patent announcement number CN217661556U discloses a sodium phenolate triple-effect evaporation device, which effectively solves the problem that the steam condenses into water and easily flows back into the concentrated sodium phenolate solution, resulting in a decrease in dehydration efficiency. The device includes an evaporator with an exhaust pipe and a drain pipe installed on its front side, an anti-backflow component installed on its outer side, a heat exchanger installed at the top of the evaporator, and an inlet pipe installed at the top of the heat exchanger. The anti-backflow component includes a water collector installed on the outer side of the evaporator, a water-holding ring installed on the inner wall of the evaporator, and connecting grooves at equal angles on the inner wall of the evaporator. The water collector and the water-holding ring are connected through these connecting grooves. This invention uses a scraper to scrape small water droplets off the inner top wall of the evaporator, and the water droplets drip from the drain plate into the water-holding ring, thus preventing the small water droplets from falling back into the concentrated material inside the evaporator, thereby improving dehydration efficiency.

[0004] Because dirt easily accumulates on the inner wall of the evaporator during long-term use, the above-mentioned technology does not have a cleaning mechanism inside the evaporator, requiring manual cleaning of the evaporator interior, which is quite troublesome; therefore, the market urgently needs to develop a triple-effect evaporation device to help people solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a triple-effect evaporator to solve the problem mentioned in the background art that dirt easily adheres to the inner wall of the evaporator after long-term use, and the existing technology does not have a cleaning mechanism inside the evaporator, requiring manual cleaning of the inside of the evaporator, which is quite troublesome.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a triple-effect evaporator, comprising an evaporator body, a rotating tube disposed at the upper middle part of the interior of the evaporator body, fan-shaped nozzles fixedly connected to the middle and lower ends of both sides of the rotating tube, support rings disposed at the upper and lower ends of the interior of the evaporator body, multiple brush rods fixedly connected between the two support rings, a circulating liquid discharge pipe fixedly connected to the lower middle part of the evaporator body, a three-way valve fixedly connected to the lower end of the circulating liquid discharge pipe, a conveying pipe fixedly connected to the lower end of the three-way valve, and a drain pipe fixedly connected to one side of the three-way valve.

[0007] Preferably, a circulating liquid return pipe is fixedly connected to one side of the upper middle part of the evaporator body, a steam discharge pipe is fixedly connected to the other side of the upper middle part of the evaporator body, and a raw material liquid inlet pipe is fixedly connected to the upper middle part of one side of the evaporator body.

[0008] Preferably, the inner side of the upper support ring is fixedly connected to the outer wall of the rotating tube by multiple support rods.

[0009] Preferably, a limiting tube is fixedly connected to the middle of the upper end of the evaporator body, and a drive box is fixedly connected to the upper end of the evaporator body outside the limiting tube. A water supply pipe is fixedly connected to the upper end of the drive box.

[0010] Preferably, the upper end of the rotating tube extends through the middle of the limiting tube into the drive box and is fixedly connected to the side wall with a first bevel gear, and the rotating tube and the limiting tube are sealed by a sealing ring.

[0011] Preferably, the lower end of the water supply pipe extends into the drive box and is connected to the upper end of the rotating pipe via a rotary joint.

[0012] Preferably, a drive motor is fixedly installed at the rear end inside the drive box, and a second bevel gear is fixedly connected to the output shaft of the drive motor, the second bevel gear meshing with the teeth of the first bevel gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, by setting a rotatable rotating tube and a fan-shaped nozzle inside the evaporator body, and cooperating with the drive motor to drive the rotation, it is possible to automatically flush the dirt on the inner wall under high pressure, which significantly improves the cleaning efficiency and convenience, and avoids the inconvenience of manual cleaning.

[0015] (2) In this utility model, by setting a support ring and a brush rod structure, the brush rod is driven to mechanically scrub the inner wall when the rotating tube rotates, which works in synergy with high-pressure water rinsing, greatly improving the cleaning effect and effectively solving the problem that the dirt on the inner wall of the traditional evaporator is difficult to remove completely.

[0016] (3) In this utility model, the design of the three-way valve enables quick switching between working state and cleaning and sewage discharge state, realizing convenient conversion between evaporation and cleaning functions, improving the practicality and ease of operation of the equipment, while the design of the sewage discharge pipe facilitates centralized discharge of sewage.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a triple-effect evaporator, comprising an evaporator body 1, a circulating liquid discharge pipe 104 fixedly connected to the lower middle of the evaporator body 1, a three-way valve 2 fixedly connected to the lower end of the circulating liquid discharge pipe 104, a conveying pipe 202 fixedly connected to the lower end of the three-way valve 2, a drain pipe 201 fixedly connected to one side of the three-way valve 2, a circulating liquid return pipe 101 fixedly connected to one side of the upper middle of the evaporator body 1, and a steam discharge pipe 102 fixedly connected to the other side of the upper middle of the evaporator body 1. A raw material liquid inlet pipe 103 is fixedly connected to the upper middle part of one side of the evaporator body 1. The raw material liquid is injected into the evaporator body 1 through the raw material liquid inlet pipe 103. The circulating liquid outlet pipe 104 and the conveying pipe 202 are connected through the three-way valve 2. The raw material liquid is conveyed to the heater through the conveying pipe 202 for heating and then flows back to the evaporator body 1 through the circulating liquid return pipe 101. The steam generated by the heating of the raw material liquid in the evaporator body 1 is discharged through the steam outlet pipe 102. The conveying pipe 202 is also connected to another evaporator body 1.

[0024] Please see Figure 3 and Figure 4 A rotating tube 3 is installed at the upper middle part of the evaporator body 1. Fan-shaped nozzles 301 are fixedly connected to the middle and lower ends of both sides of the rotating tube 3. A limiting tube 105 is fixedly connected to the middle of the upper end of the evaporator body 1. A drive box 4 is fixedly connected to the upper end of the evaporator body 1 and outside the limiting tube 105. A water supply pipe 401 is fixedly connected to the upper end of the drive box 4. The upper end of the rotating tube 3 extends through the middle of the limiting tube 105 into the drive box 4 and is fixedly connected to the side wall of the drive box 4. The rotating tube 3 and the limiting tube 105 are sealed by a sealing ring. The lower end of the water supply pipe 401 extends into the drive box 4 and connects with the rotating tube 3. The upper end is connected via a rotary joint 402. A drive motor 403 is fixedly installed at the rear end inside the drive box 4. A second bevel gear 404 is fixedly connected to the output shaft of the drive motor 403. The second bevel gear 404 meshes with the teeth of the first bevel gear 302. After the evaporator body 1 has been used for a long time, water is pressurized and supplied to the rotating tube 3 through the water supply pipe 401. This causes the cleaning water inside the rotating tube 3 to be sprayed onto the inner wall of the evaporator body 1 through multiple fan-shaped nozzles 301. At the same time, the drive motor 403 drives the rotating tube 3 to rotate, causing the multiple fan-shaped nozzles 301 to rotate synchronously, thereby rinsing the dirt on the inner wall of the evaporator body 1.

[0025] Please see Figure 2The evaporator body 1 has support rings 5 ​​at both the upper and lower ends of the middle part. Multiple brush rods 501 are fixedly connected between the two support rings 5. The inner side of the upper support ring 5 is fixedly connected to the outer wall of the rotating tube 3 by multiple support rods 502. When the rotating tube 3 rotates, it drives the two support rings 5 ​​to rotate synchronously. The multiple brush rods 501 between the two support rings 5 ​​brush the inner wall of the evaporator body 1. The three-way valve 2 is used to switch the circulating liquid discharge pipe 104 to the sewage discharge pipe 201, and the sewage inside the evaporator body 1 is discharged through the sewage discharge pipe 201.

[0026] Working Principle: During operation, the raw material liquid is injected into the evaporator body 1 through the raw material liquid inlet pipe 103. The three-way valve 2 connects the circulating liquid outlet pipe 104 to the delivery pipe 202. The raw material liquid is then transported to the heater via the delivery pipe 202 for heating, and then flows back into the evaporator body 1 through the circulating liquid return pipe 101 for evaporation. The generated steam is discharged through the steam outlet pipe 102. When cleaning is required, the raw material inlet is closed, and high-pressure cleaning water is injected into the rotating pipe 3 through the water supply pipe 401. The drive motor 403 drives the first bevel gear 302 and the rotating pipe 3 to rotate via the second bevel gear 404, causing the fan-shaped nozzle 301 to rotate and spray water to rinse the inner wall. Simultaneously, the support ring 5 drives the brush rod 501 to rotate and brush away dirt. After cleaning, the three-way valve 2 is switched to connect the circulating liquid outlet pipe 104 to the sewage outlet pipe 201 to discharge the wastewater, achieving automated cleaning and effectively solving the problem of inconvenience in manual cleaning.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
