Description

Technical Field

[0001] This utility model belongs to the field of cleaning system technology, and in particular relates to an automatic cleaning system for MVR evaporators. Background Technology

[0002] In industrial production, especially in processes involving evaporation, MVR (Mechanical Vapor Recompression) evaporators are widely used as highly efficient and energy-saving equipment. However, with prolonged operation, various impurities, dirt, and crystals gradually accumulate inside the evaporator. These deposits not only affect the heat transfer efficiency of the evaporator but may also lead to frequent equipment failures and shorten the equipment's service life. Therefore, it is crucial to clean MVR evaporators regularly and effectively.

[0003] Traditional cleaning methods often have many limitations. For example, in the preparation of cleaning solutions, different types of cleaning solutions are usually mixed directly in one container for storage and use. However, this practice is prone to failure due to mixed storage, because cleaning solutions of different properties may react chemically, causing them to lose their original cleaning effectiveness. Moreover, due to the lack of effective stirring methods, solute precipitation is likely to occur in the cleaning solution in the tank. When a portion of such a cleaning solution is taken for cleaning, uneven concentration will occur. On the one hand, areas with insufficient concentration cannot effectively remove stubborn stains on the evaporator surface, forming cleaning dead zones. On the other hand, areas with excessively high concentration may cause excessive corrosion to the evaporator material, further damaging the integrity and performance of the equipment. Therefore, an automatic cleaning system for MVR evaporators is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an automatic cleaning system for MVR evaporators. By setting up a water supply component, specifically, a second motor drives a second rotating shaft to rotate a stirring impeller at high speed, ensuring uniform mixing of the cleaning agent and water. A three-way electrically controlled valve switches to water supply mode, and the cleaning solution flows into the main inlet pipe through a branch pipe. Multiple storage tanks store different cleaning solutions to reduce the likelihood of failure. The stirring impeller continuously mixes the liquid, solving many limitations of traditional cleaning methods. For example, in the preparation of the cleaning solution, different types of cleaning solutions are usually directly mixed in one container for storage and use. However, this practice easily leads to failure due to mixed storage, as different types of cleaning solutions may react chemically, causing them to lose their original cleaning effectiveness. Moreover, due to the lack of effective stirring, solute precipitation is likely to occur in the cleaning solution within the tank. When a portion of such a cleaning solution is used for cleaning, uneven concentration occurs. On the one hand, areas with insufficient concentration cannot effectively remove stubborn stains from the evaporator surface, creating cleaning dead zones. On the other hand, areas with excessively high concentration may cause excessive corrosion of the evaporator material, further damaging the integrity and performance of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an automatic cleaning system for MVR evaporators, comprising a chamber as the target carrier for cleaning. The system is characterized by further including a cleaning mechanism that abuts against the inner wall and outer surface of the chamber. The cleaning mechanism efficiently cleans the chamber through water supply, water delivery, cleaning, and vibration. The cleaning mechanism includes a water supply assembly comprising three water storage tanks. A motor is bolted to the top of each of the three water storage tanks, and two agitator impellers are installed inside each of the three water storage tanks.

[0006] Furthermore, the cleaning mechanism also includes a cleaning component that extends into the interior of the chamber and is driven by power to clean the inner wall of the chamber; a vibration component that is linked to the cleaning component and is used to assist in cleaning the cleaning component and the chamber; and a water supply component that is installed on the top of the chamber and is used to supply water to the cleaning chamber. An inlet pipe is welded to the side of the chamber, and a drain pipe is welded to the bottom of the chamber. Both the drain pipe and the inlet pipe are equipped with electrically controlled valves.

[0007] Furthermore, the bottom output ends of the three motors are all connected to the rotating shafts via couplings. The three rotating shafts penetrate the water storage tank and extend into it. The outer surfaces of the three rotating shafts are rotatably connected to the inside of the water storage tank. Several stirring impellers are arranged in groups of two. The interiors of the three groups of stirring impellers are welded to the outer surfaces of the rotating shafts. Water supply branch pipes are installed at the side outlets of the three water storage tanks.

[0008] Furthermore, the cleaning assembly includes a motor, which is bolted to the top of the chamber. The bottom output end of the motor is connected to a rotating shaft via a coupling. The rotating shaft passes through the chamber and extends into the cavity. A support sleeve is provided inside the chamber. The inside of the support sleeve is welded to the outer surface of the rotating shaft. Cleaning brush holders are welded to the left and right sides of the support sleeve. The side of the two cleaning brush holders away from the support sleeve contacts the inner wall of the chamber.

[0009] Furthermore, the vibration assembly includes an impact disk, the inner ring of which is rotatably connected to the outer surface of a rotating shaft, a return spring is sleeved on the outer surface of the rotating shaft, the top of the return spring is connected to the top of the inner wall of the chamber, the bottom of the return spring is connected to the top of the impact disk, a rotating disk is provided on the side of the impact disk away from the return spring, the side of the rotating disk away from the impact disk is welded to the top of the support sleeve, the impact disk and the rotating disk are in contact on their corresponding sides, and both the impact disk and the rotating disk are provided with protrusions on their corresponding sides.

[0010] Furthermore, the water delivery assembly includes a high-pressure water pump, which is mounted on the top of the cabin via a mounting bracket. A water delivery pipe is installed at the outlet of the high-pressure water pump, and the water delivery pipe penetrates the cabin and extends into the cavity. A booster distribution box is welded to the top of the inner wall of the cabin. The side of the water delivery pipe away from the high-pressure water pump is connected to the inlet of the booster distribution box. Several outlets at the bottom of the booster distribution box are equipped with high-pressure nozzles. A main water inlet pipe is installed at the inlet of the high-pressure water pump. The side of the main water inlet pipe away from the high-pressure water pump is connected to the side of three branch water delivery pipes away from the water storage tank. A three-way electrically controlled valve is provided at the connection between the main water inlet pipe and the three branch water delivery pipes.

[0011] This utility model has the following beneficial effects: 1. This utility model, by setting up a water supply component, specifically, the second motor starts and drives the second rotating shaft to drive the stirring impeller to rotate at high speed, so that the cleaning agent and water are mixed evenly. The three-way electric control valve switches to the water supply mode, and the cleaning liquid flows into the main water inlet through the water supply branch pipe. Multiple water storage tanks store different cleaning liquids to reduce the possibility of failure. The stirring impeller continuously mixes the liquid, improving the stability and consistency of the output concentration of the cleaning liquid each time, and reducing cleaning dead corners and corrosion risks.

[0012] 2. This utility model incorporates a vibration component. Specifically, when the support sleeve rotates, it synchronously drives the rotating disk to rotate. The impact of the impact disk causes it to move upward and compresses the return spring to store energy. The return spring rebounds, causing the impact disk to return to its original position and re-engage with the rotating disk to generate a reaction force vibration. This vibration is transmitted through the support sleeve to the cleaning brush holder, causing high-frequency micro-vibration on the inner wall of the chamber. This disrupts the molecular adhesion of stubborn scale, causing the hard scale to fall off. Combined with high-pressure water flow, the scale particles are flushed away. At the same time, the cleaning brush holder itself vibrates to achieve self-cleaning, reducing the adhesion of impurities and secondary pollution, maintaining edge flatness and fitting accuracy, improving scraping efficiency, and reducing the frequency of downtime and adjustment due to scale buildup.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5 As shown, this utility model is an automatic cleaning system for an MVR evaporator, including a chamber 111, which serves as the target carrier for cleaning. The system is characterized by a cleaning mechanism 2, which abuts against the inner wall and outer surface of the chamber 111. The cleaning mechanism 2 efficiently cleans the chamber 111 through water supply, water delivery, cleaning, and vibration. The cleaning mechanism 2 includes a water supply component 24, which comprises three water storage tanks 241. A motor 242 is bolted to the top of each of the three water storage tanks 241, and two stirring impellers 244 are installed inside each of the three water storage tanks 241.

[0019] The cleaning mechanism 2 also includes a cleaning component 21, which extends into the cavity of the chamber 111. The cleaning component 21 is driven by power to clean the inner wall of the chamber 111. A vibration component 22 is also included, which is linked with the cleaning component 21 and is used to assist in cleaning the cleaning component 21 and the chamber 111. A water supply component 23 is also included, which is installed on the top of the chamber 111 and is used to supply water to the cleaning chamber 111. An inlet pipe 114 is welded to the side of the chamber 111, and a drain pipe 112 is welded to the bottom of the chamber 111. Both the drain pipe 112 and the inlet pipe 114 are equipped with an electric control valve 113.

[0020] The bottom output ends of three motors 242 are all connected to rotating shafts 243 via couplings. All three rotating shafts 243 pass through the water storage tank 241 and extend into it. The outer surfaces of the three rotating shafts 243 are rotatably connected to the inside of the water storage tank 241. Several stirring impellers 244 are arranged in pairs. The interiors of the three sets of stirring impellers 244 are welded to the outer surfaces of the rotating shafts 243. Water supply branch pipes 245 are installed at the side outlets of the three water storage tanks 241. When the motors 242 are started, they drive the rotating shafts 243 to rotate the stirring impellers 244 at high speed, so that the cleaning agent and water are mixed evenly. The three-way electric control valve 236 switches to the water supply mode, and the cleaning liquid flows into the main water inlet pipe 235 through the water supply branch pipe 245. The multiple water storage tanks 241 store different cleaning liquids to reduce the possibility of failure. The stirring impellers 244 continuously mix the liquid, improving the stability and consistency of the output concentration of the cleaning liquid each time, and reducing cleaning dead corners and corrosion risks.

[0021] The cleaning assembly 21 includes a motor 211, which is bolted to the top of the chamber 111. The bottom output end of the motor 211 is connected to a rotating shaft 212 via a coupling. The rotating shaft 212 passes through the chamber 111 and extends into the cavity. A support sleeve 213 is installed inside the chamber 111. The inner surface of the support sleeve 213 is welded to the outer surface of the rotating shaft 212. Cleaning brush holders 214 are welded to the left and right sides of the support sleeve 213. The side of each cleaning brush holder 214 away from the support sleeve 213 contacts the inner wall of the chamber 111. The vibration assembly 22 includes an impact disc 221. The inner ring of the impact disc 221 is rotatably connected to the outer surface of the rotating shaft 212. A return spring 222 is sleeved on the outer surface of the rotating shaft 212. The top of the return spring 222 is connected to the top of the inner wall of the chamber 111, and the bottom of the return spring 222 is connected to the top of the impact disc 221. A [missing information - likely a type of support] is installed on the side of the impact disc 221 away from the return spring 222. The rotating disk 223 is welded to the top of the support sleeve 213 on the side away from the impact disk 221. The impact disk 221 contacts the corresponding side of the rotating disk 223. Both the impact disk 221 and the rotating disk 223 have protrusions on their corresponding sides. When the support sleeve 213 rotates, it synchronously drives the rotating disk 223 to rotate. The impact disk 223 impacts the impact disk 221, causing it to move upward and compress the return spring 222 to store energy. The return spring 222 rebounds and drives the impact disk 221 to return to its original position. It then contacts the rotating disk 223 again, generating a reaction force vibration. This vibration is transmitted to the cleaning brush holder 214 through the support sleeve 213, causing high-frequency micro-vibration on the inner wall of the chamber 111. This disrupts the molecular adhesion of stubborn scale, causing the hard scale to fall off. Combined with the high-pressure water flow, the scale particles are flushed away. At the same time, the cleaning brush holder 214 vibrates itself to achieve self-cleaning, reducing the adhesion of impurities and secondary pollution, maintaining edge flatness and fitting accuracy, improving scraping efficiency, and reducing the frequency of downtime and adjustment due to scale jamming.

[0022] The water delivery assembly 23 includes a high-pressure water pump 231, which is mounted on the top of the chamber 111 via a mounting bracket. A water delivery pipe 232 is installed at the outlet of the high-pressure water pump 231. The water delivery pipe 232 passes through the chamber 111 and extends into the cavity. A booster distribution box 233 is welded to the top of the inner wall of the chamber 111. The side of the water delivery pipe 232 away from the high-pressure water pump 231 is connected to the inlet of the booster distribution box 233. Several outlets at the bottom of the booster distribution box 233 are equipped with high-pressure nozzles 234. A main water inlet pipe 235 is installed at the inlet of the high-pressure water pump 231. The side of the main water inlet pipe 235 away from the high-pressure water pump 231 is connected to the side of three water delivery branch pipes 245 away from the water storage tank 241. A three-way electrically controlled valve 236 is provided at the connection between the main water inlet pipe 235 and the three water delivery branch pipes 245.

[0023] A specific application of this embodiment is as follows: In use, the system first closes the solenoid valve 113 of the feed pipe 114 of the MVR evaporator to stop feeding. Simultaneously, it opens the solenoid valve 113 of the drain pipe 112 to drain the remaining material to be evaporated from the chamber 111, preventing the material from mixing and contaminating the cleaning solution. Then, clean water is injected into the water storage tank 241, or a special descaling cleaning agent is added as needed. The second motor 242 starts, driving the impeller 244 on the second shaft 243 to rotate at high speed, ensuring the cleaning agent and water are fully and evenly mixed. Subsequently, the three-way solenoid valve 236 switches to water supply mode, and the cleaning solution enters the main water inlet pipe 235 through the branch pipe 245, preparing for subsequent high-pressure rinsing. The high-pressure water pump 231 starts, pressurizing the cleaning solution in the main water inlet pipe 235 and delivering it to the booster distribution box 233 through the water supply pipe 232. The booster distribution box 233 then distributes the high-pressure cleaning solution... The solution is evenly distributed to multiple high-pressure nozzles 234. The high-pressure nozzles 234 spray high-pressure columnar or mist-like water jets onto the inner wall of the chamber 111. On the one hand, this directly flushes away the fine scale particles remaining after mechanical cleaning. On the other hand, the water jet impact force breaks down the adhesion between stubborn scale and the inner wall. If the cleaning solution contains a descaling agent, it can also soften the scale through chemical action, further improving the cleaning effect. Multiple water storage tanks 241 can store different types of cleaning solutions separately, reducing the failure problem caused by mixed storage. The stirring impeller 244 can continuously mix the cleaning solutions in the tank, preventing solute precipitation and improving the uniformity of the cleaning solution concentration each time, thereby improving the stability of the cleaning effect and reducing the problem of cleaning dead corners due to insufficient local concentration or excessive corrosion of the evaporator material due to excessive concentration. Simultaneously, motor 211 is started to work. The output torque of motor 211 is transmitted to support sleeve 213 through shaft 212. Support sleeve 213 drives the cleaning brush frame 214 fixedly connected to it to rotate synchronously. The bristles on the cleaning brush frame 214 are in close contact with the inner wall of the chamber 111. Through rotational friction and the action of cleaning fluid, the scale on the inner wall surface is scraped off, clearing obstacles for subsequent high-pressure flushing. At the same time, during the rotation of support sleeve 213, rotating disk 223 is driven to rotate synchronously. During the rotation of rotating disk 223, it impacts impact disk 221. Impact disk 221 moves upward under the impact force. During the upward movement of impact disk 221, it simultaneously compresses return spring 222. Return spring 222 is limited by the inner wall of chamber 111 and will contract and store energy. At the same time, return spring 222 will generate a certain rebound force and drive impact disk 221 to return to its original position. During the reset process, disk 221 will re-contact with rotating disk 223, causing rotating disk 223 to vibrate due to the reaction force. Rotating disk 223 then transmits the vibration frequency to cleaning brush holder 214 through support sleeve 213. This vibration of cleaning brush holder 214 causes high-frequency micro-vibrations on the inner wall of chamber 111. This vibration breaks down the intermolecular adhesion between stubborn scale and the inner wall, causing tightly adhered hard scale to detach. Simultaneously, high-pressure water flow helps to flush the detached scale particles away from the inner wall. During the high-frequency vibration of cleaning brush holder 214, dirt adhering to its own surface also detaches, reducing the adhesion of impurities to the surface of cleaning brush holder 214, improving its cleanliness, and reducing secondary pollution. Vibration cleaning also effectively removes adhering dirt, maintains the flatness of the edges of cleaning brush holder 214 and its precise fit with the inner wall of chamber 111, improving the efficiency of the scraping action and reducing the risk of secondary contamination. To address the frequent downtime and adjustment needs caused by scale buildup, after the cleaning process is completed, motor 1 (211), motor 2 (242), and high-pressure water pump 231 stop operating, and the three-way solenoid valve 236 closes the water supply passage. At the same time, the solenoid valve 113 of the drain pipe 112 remains open, and the cleaning waste liquid containing scale particles in the chamber 111 is discharged through the drain pipe 112. The waste liquid can be introduced into the wastewater treatment system as needed. After the waste liquid is drained, the solenoid valve 113 of the drain pipe 112 is closed, and all structural components are returned to their initial positions. If the MVR evaporator needs to be restarted later, the solenoid valve 113 of the feed pipe 114 is opened to restore the normal feeding and evaporation process.
