Description

Technical Field

[0001] The utility model belongs to the technical field of chemical equipment, and specifically relates to a self-cleaning reaction system. Background Art

[0002] In the chemical, pharmaceutical, food and beverage industries, many products require the use of reaction tanks. After the production task is completed, not only will various raw materials, reactants and impurities remain on the tank wall, but the internal components such as the agitator, connectors and coils in the reaction tank will also be attached with a lot of dirt, which requires deep cleaning. However, the structure of the internal components of the reaction tank is often more complicated, with many gaps, corners and hidden areas, forming many blind spots for cleaning. If the dirt remains, it will contaminate the new product when it is put into production again, increasing the risk of quality failure. At present, the industry mostly uses two methods to clean reaction tanks: manual wiping and flushing or installing a spray ball on the top of the reaction tank. The former process is cumbersome, time-consuming, requires a lot of manpower, and has low efficiency. Although the latter saves manpower, it is limited by the installation position and spray range, and cannot accurately cover the internal area of ​​the reaction tank, and the cleaning degree is poor.

[0003] At the same time, most of the cleaning fluids used to clean the reaction tanks are directly discharged, which not only increases the cleaning and processing costs of the reaction tanks, but also causes serious waste of resources. On the one hand, the cleaning fluid itself has a certain purchase cost, and frequent purchases of new cleaning fluids will have an adverse impact on the company's cost control and economic benefits. On the other hand, after the initial cleaning, most of the cleaning fluids only dissolve and carry away dirt and impurities. Through appropriate filtering, purification and other treatment methods, they can restore a certain degree of cleaning effectiveness and be put back into use. Utility Model Content

[0004] The utility model aims to provide a self-cleaning reaction system, which can eliminate blind spots in cleaning and ensure that no dirt remains, while reducing resource waste of cleaning fluid and lowering corporate procurement costs.

[0025] The present invention will be specifically described and illustrated below in conjunction with the embodiments.

[0026] Example 1

[0028] The combination of the spray ball 2 and the nozzle 5 can fully cover the internal space area of ​​the reaction tank 1, eliminate the blind area of ​​cleaning, and achieve a high degree of cleaning; the cleaning liquid after the initial cleaning is driven by the circulation pump 10 to start flowing in the closed loop 9, and the cleaning liquid first flows into the filter 11 to intercept the solid dirt particles and impurities therein, and then the cleaning liquid enters the cleaning tank 12, and the cleaning tank 12 is provided with chemical cleaning agents, which are fully mixed with the cleaning liquid to further purify the cleaning liquid; finally, the cleaning liquid is pressurized by the high-pressure pump 13 and enters the heater 14, and the heater 14 improves the cleaning efficiency of the cleaning liquid by heating.

[0029] The closed loop 9 is provided with a drain pipe 15, which is located between the high-pressure pump 13 and the heater 14. The drain pipe 15 is used to discharge the cleaning liquid that cannot be reused.

[0030] The spray ball 2 includes a spherical shell 201, which is a hollow sphere. The spherical shell 201 is provided with a plurality of spray holes 202. The cleaning liquid entering the spherical shell 201 can be evenly sprayed around through the spray holes 202, thereby flushing the inside of the reaction tank 1 from multiple angles to improve the cleaning efficiency.

[0031] A driving impeller 203 is provided inside the spherical shell 201 . Two groups of support rods 204 are fixedly provided at the bottom of the driving impeller 203 . One end of the two groups of support rods 204 away from the driving impeller 203 is fixedly connected to the inner wall of the spherical shell 201 .

[0032] Two sets of support rods 204 are symmetrically arranged inside the ball shell 201 in cooperation with the driving impeller 203. When the cleaning liquid enters the spray ball 2, the driving impeller 203 is impacted and rotates, thereby driving the ball shell 201 to rotate, so that the spray hole 202 can realize dynamic water spraying, ensuring that there is no dead angle in the cleaning.

[0033] A rotating joint 205 is disposed on the top of the spherical shell 201 , and a rotating connector 206 is disposed outside the rotating joint 205 . One end of the rotating joint 205 close to the spherical shell 201 is connected to the inside of the spherical shell 201 .

[0034] One end of the rotating connector 206 away from the ball shell 201 is connected to the spray branch pipe 3. The rotating joint 205 is arranged in cooperation with the rotating connector 206, which ensures the flexible rotation of the ball shell 201 on the one hand, and allows the cleaning liquid to enter the ball shell 201 smoothly on the other hand.

[0035] The nozzle 5 includes a nozzle 501, on which a hinge seat 502 is provided, on which two sets of telescopic rods 503 are rotatably provided, and one end of the telescopic rod 503 away from the hinge seat 502 is rotatably connected to a fixed seat 504, which is fixedly provided on the side wall of the inner cavity of the reaction tank 1. By adjusting the length of the telescopic rod 503, the nozzle 501 can be accurately directed to the part to be cleaned, thereby improving the targeted cleaning.

[0036] One end of the nozzle 501 close to the hinge seat 502 is connected to a telescopic hose 505 , and one end of the telescopic hose 505 away from the nozzle 501 passes through the hinge seat 502 , the fixing seat 504 and the inner cavity side wall of the reaction tank 1 in sequence.

[0037] One end of the telescopic hose 505 away from the nozzle 501 is connected to the nozzle branch pipe 6. The telescopic hose 505 can ensure the stable transmission of the cleaning liquid and can be extended and retracted with the adjustment of the nozzle 501, ensuring that the nozzle 501 can work normally at various angles.

[0038] Working principle and process:

[0039] 1. Preparation before cleaning

[0040] When the reaction tank 1 completes the production task, the liquid inlet main pipe 8 is connected to an external cleaning liquid supply source so that the cleaning liquid can smoothly enter the reaction tank 1 .

[0041] 2. Cleaning stage

[0042] Spray ball 2 cleaning

[0043] Open the valve on the liquid inlet pipe 4, and the cleaning liquid is diverted to the spray branch pipe 3 through the liquid inlet main pipe 8 and enters the two groups of spray balls 2 at the top of the inner cavity of the reaction tank 1. After the cleaning liquid enters the ball shell 201, it is sprinkled to the surroundings through a plurality of groups of spray holes 202, flushing the upper tank wall area of ​​the reaction tank 1 at multiple angles. The driving impeller 203 inside the ball shell 201 rotates under the impact of the cleaning liquid, driving the ball shell 201 to rotate, so that the spray holes 202 can realize dynamic water spraying, ensuring that there is no dead angle in the cleaning of the upper part of the reaction tank 1.

[0044] Nozzle 5 cleaning

[0045] Close the valve on the liquid inlet pipe 4, open the valve on the nozzle branch pipe 6, and the cleaning liquid reaches the nozzle 5. By adjusting the length of the two sets of telescopic rods 503 on the hinged seat 502, the nozzle 501 is directed to the part to be cleaned inside the reaction tank 1. The telescopic hose 505 is extended and retracted as the nozzle 501 is adjusted to ensure the normal operation of the nozzle 501.

[0046] During the cleaning process of the nozzles 5 , in order to achieve more targeted cleaning of the interior of the reaction tank 1 , the valves on a single group of nozzle branches 6 are operated in sequence, so that the two groups of nozzles 5 perform the cleaning work alternately.

[0047] Spray ball 2 cleans again

[0048] Close the valve on the nozzle branch pipe 6, open the valve on the liquid inlet pipe 4, and let the spray ball 2 work again to consolidate and clean the wall of the reaction tank 1 to ensure that there is no dirt left on the tank wall.

[0049] 3. Cleaning fluid circulation treatment stage

[0050] During the entire cleaning process, the closed loop 9 at the bottom of the reaction tank 1 is continuously operated, and the cleaning liquid after the initial cleaning is driven by the circulation pump 10 to flow into the filter 11, and the filter 11 intercepts the solid dirt particles and impurities therein, and the filtered cleaning liquid enters the cleaning tank 12, and the chemical cleaning agent in the cleaning tank 12 is fully mixed with the cleaning liquid to further purify the cleaning liquid. The purified cleaning liquid is pressurized by the high-pressure pump 13, and then enters the heater 14 for heating. The heated and pressurized cleaning liquid is again transported to the spray ball 2 and the nozzle 5 through the liquid inlet main pipe 8 to realize the recycling of the cleaning liquid.

[0051] 4. Drainage Stage

[0052] After the cleaning liquid has been recycled three times, the valve of the drain pipe 15 is opened to discharge the cleaning liquid that cannot be reused, and then the valve of the drain pipe 15 is closed and new cleaning liquid is added to carry out the next round of cleaning.
