Description

Technical Field

[0001] This utility model relates to the field of reactor cleaning, specifically to a device for cleaning the inner wall of a chemical reactor. Background Technology

[0002] Chemical reaction vessels, as crucial equipment in chemical production, are widely used in various chemical reaction processes. In chemical production, reaction vessels undertake multiple key tasks such as mixing, heating, cooling, and chemical reactions. However, during long-term use, a large amount of reactants, impurities, and dirt accumulates on the inner walls of the reaction vessels. These residues not only affect the reaction efficiency and product quality but may also cause corrosion and other problems, thus shortening the service life of the reaction vessels. Therefore, regular cleaning of the inner walls of chemical reaction vessels is an essential part of the chemical production process.

[0003] Currently, existing methods for cleaning the inner walls of chemical reactors have the following shortcomings. Firstly, some methods rely on manual cleaning, which is not only labor-intensive and inefficient, but also poses a health risk to cleaning personnel due to the limited space inside the reactor and the potential presence of harmful gases. Secondly, while some mechanical cleaning equipment improves efficiency to some extent, it still falls short in terms of comprehensiveness and thoroughness. For example, it is difficult to effectively remove stubborn stains from the reactor's inner walls, and it also cannot adequately clean the bottom of the reactor.

[0004] In order to solve the problems existing in the above-mentioned technologies, it is urgent to design a new type of chemical reactor inner wall cleaning device. Utility Model Content

[0005] In view of this, the present invention provides a chemical reactor inner wall cleaning device, which uses a mechanical scraper to remove stubborn dirt and uses liquid rinsing to clean the tank wall and remove the scraped dirt, thereby achieving all-round cleaning of the reactor inner wall and improving cleaning efficiency and quality.

[0006] To address the aforementioned technical problems, this utility model provides a chemical reactor inner wall cleaning device, comprising a base plate with a brushing mechanism for cleaning the reactor interior. The brushing mechanism includes a scraper assembly movably mounted inside the reactor via a lifting component, and the scraper assembly is rotatably mounted inside the reactor by a driving component. The brushing mechanism also includes a fluid pipe mounted on the lifting component and several nozzles mounted on the fluid pipe. That is, through the rotating scraper assembly and the liquid spraying from the nozzles on the fluid pipe, stubborn dirt is removed by mechanical scraping, while the liquid washes clean the reactor wall and removes the scraped dirt, thereby achieving comprehensive cleaning of the reactor inner wall and improving cleaning efficiency and quality.

[0007] The lifting assembly includes a fixed base mounted on a base plate. A sleeve is mounted on the fixed base, and a telescopic column is slidably installed inside the sleeve. A top seat is fixed to the top of the telescopic column, and a limit block is installed below the top seat and mounted on the telescopic column. In other words, the lifting assembly allows the scraper assembly to be adjusted vertically according to the height of the reactor, thereby enabling cleaning of the inner wall of the reactor at different heights. This enhances the applicability and flexibility of the cleaning device and ensures that all parts of the reactor's inner wall are effectively cleaned.

[0008] A fixing plate is connected between the top seat and the limiting block to fix the drive component. That is, by setting the fixing plate between the top seat and the limiting frame, it is ensured that the drive component will not shake or shift during operation, thereby ensuring that the drive component can work normally and efficiently, providing stable power support for the rotation of the scraper kit, and improving the reliability of the cleaning device.

[0009] The driving component includes a geared motor mounted on a fixed plate, with a drive shaft connected to the geared motor, and a scraper assembly mounted on the drive shaft. That is, the geared motor's rotation speed is adjusted as needed, allowing the scraper assembly to scrape the inner wall of the reactor at a suitable speed. This ensures effective scraping while avoiding damage to the reactor's inner wall due to excessive speed, thus improving the safety and effectiveness of the cleaning process.

[0010] The scraper assembly includes mounting blocks symmetrically mounted on the drive shaft. Several support arms are provided on the mounting blocks, and a tank wall scraper is connected between two symmetrically mounted support arms. A tank bottom scraper is also securely mounted at the bottom of the drive shaft. In other words, the symmetrically arranged support arms and tank wall scrapers can fully cover the walls of the reactor, while the tank bottom scraper cleans the bottom of the reactor, achieving comprehensive scraping of the reactor's interior and further improving the thoroughness of the cleaning.

[0011] The scrubbing mechanism also includes a water tank mounted on the base plate for supplying liquid to the fluid pipe, and an axial flow pump mounted on the water tank. That is, the water tank and axial flow pump ensure a continuous supply of cleaning liquid to the fluid pipe, guaranteeing liquid spraying from the nozzles, enabling the cleaning process to continue continuously and improving cleaning efficiency.

[0012] A water pump is connected to the water tank via a suction pipe, and a water supply pipe is connected to the fluid pipe via the axial flow pump. This allows for liquid transport through the suction and supply pipes, clearly defining the liquid flow path and ensuring smooth delivery of the liquid from the water tank to the fluid pipe, and finally, it is ejected from the nozzle. This improves the stability and reliability of the liquid supply, ensuring the normal operation of the cleaning device.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. The drive shaft is rotated by a geared motor. During the rotation, the scraper on the barrel wall on the drive shaft can thoroughly scrub the inner wall of the reactor, and the scraper on the bottom of the barrel can clean the bottom of the reactor. This effectively removes dirt from the inner wall and bottom of the reactor, resulting in good cleaning effect and high efficiency.

[0015] 2. The height of the scraper assembly and fluid pipe can be flexibly adjusted by the lifting component, so that the device can adapt to reactors of different heights, thus improving the versatility and applicability of the device.

[0016] 3. The liquid supply system, consisting of a water tank, an axial flow pump, a suction pipe, and a supply pipe, draws liquid from the tank using the axial flow pump, delivers it to the fluid pipe via the supply pipe, and finally sprays it out from the nozzle. Simultaneously with the scraper assembly's brushing action, fluid rinsing further enhances the cleaning effect and promptly removes the scrubbed dirt.

[0017] 4. The geared motor provides stable and controllable power for the rotation of the scraper assembly, ensuring that the scraper assembly rotates smoothly in the reactor and ensuring the smooth progress of the cleaning work. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figure 1-4 As shown: This embodiment provides a chemical reactor inner wall cleaning device, including a base plate 10, on which a scrubbing mechanism 20 for cleaning the inside of the reactor is provided. The scrubbing mechanism 20 includes a scraper kit movably disposed inside the reactor via a lifting assembly 21, and the scraper kit is rotatably disposed inside the reactor by means of a driving component 22. The scrubbing mechanism 20 also includes a fluid pipe installed on the lifting assembly 21, and several nozzles disposed on the fluid pipe. The scrubbing mechanism 20 allows the scraper kit to move inside the reactor via the lifting assembly 21, enabling it to scrape the inner wall of the reactor at different heights. Simultaneously, the driving component 22 drives the scraper kit to rotate, during which the scraper kit fully contacts the inner wall of the reactor, scraping off the dirt adhering to the inner wall. The several nozzles on the fluid pipe can spray cleaning liquid onto the inner wall of the reactor, which, in conjunction with the scraping of the scraper kit, further improves the cleaning effect. The liquid can lubricate and dissolve the dirt, making it easier for the dirt to be scraped off by the scraper, and at the same time, it can flush away the scraped dirt.

[0025] The lifting assembly 21 includes a fixed base 211 mounted on the base plate 10. A sleeve 212 is provided on the fixed base 211. A telescopic column 213 is slidably arranged inside the sleeve 212. The telescopic column 213 can slide inside the sleeve 212 on the fixed base 211. The height of the telescopic column 213 is changed by sliding inside the sleeve 212. A top seat 214 is fixed on the top of the telescopic column 213. When the telescopic column 213 slides, the top seat 214 moves up and down accordingly. A limit block 215 is provided below the top seat 214 and is mounted on the telescopic column 213. The limit block 215 can limit the sliding range of the equipment subsequently installed on the telescopic column 213 to a certain extent, prevent it from sliding excessively, and ensure the stability and safety of the lifting process.

[0026] A fixing plate 216 for fixing the drive component 22 is connected between the top seat 214 and the limiting block 215. By utilizing the relative positional relationship between the top seat 214 and the limiting block 215, the drive component 22 is fixed between the two, so that the drive component 22 will not shake or shift during operation, ensuring the stable operation of the drive component 22, and thus ensuring the normal rotation of the scraper assembly.

[0027] The drive unit 22 includes a geared motor mounted on a fixed plate 216, a drive shaft connected to the geared motor, and a scraper assembly mounted on the drive shaft. When the geared motor is working, it converts electrical energy into mechanical energy, driving the drive shaft to rotate. Since the scraper assembly is mounted on the drive shaft, the rotation of the drive shaft will drive the scraper assembly to rotate together, thereby realizing the scraping action of the scraper assembly on the inner wall of the reactor.

[0028] The scraper assembly includes mounting blocks symmetrically mounted on the drive shaft. Several support arms are provided on the mounting blocks, and a tank wall scraper is connected between two symmetrical support arms. A tank bottom scraper is also securely mounted at the bottom of the drive shaft. When the drive shaft rotates, the tank wall scraper rotates accordingly, making full contact with the tank wall of the reactor to scrape away dirt.

[0029] The scrubbing mechanism 20 also includes a water tank disposed on the base plate 10 for supplying liquid to the fluid pipe, and an axial flow pump mounted on the water tank. The water tank is used to store the cleaning liquid, and the axial flow pump is used to extract the liquid from the water tank and transport it to other locations.

[0030] A water pumping pipe is installed between the axial flow pump and the water tank, and a water supply pipe is installed between the axial flow pump and the fluid pipe. When the axial flow pump is working, the pumped liquid is transported to the fluid pipe through the water supply pipe, and then sprayed onto the inner wall of the reactor through the nozzle on the fluid pipe, thus supplying the cleaning liquid.

[0031] The method of using this utility model is as follows: Place the reactor to be cleaned on the base plate 10, and add an appropriate amount of liquid for cleaning the inner wall of the reactor into the water tank. Then, by controlling the sliding of the telescopic column 213 in the sleeve 212, it is raised or lowered, driving the top seat 214 and the scraper kit installed on it to reach the appropriate cleaning position inside the reactor. Turn on the reduction motor installed on the fixed plate 216. The reduction motor drives the scraper kit to rotate through the transmission shaft. The rotating scraper kit scrapes the inner wall and bottom of the reactor to remove the attached dirt. While the tank wall is being scrubbed by the scraper kit, start the axial flow pump. The axial flow pump draws the cleaning liquid from the water tank through the water pipe, and then delivers the liquid to the fluid pipe through the water supply pipe. Finally, several nozzles on the fluid pipe spray the cleaning liquid onto the inner wall of the reactor, which assists the scraper kit in rinsing the dirt and also plays a lubricating role, reducing the friction between the scraper and the inner wall.

[0032] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
