Description

Technical Field

[0001] This application relates to the field of industrial equipment cleaning, specifically to a cleaning device for reaction vessels. Background Technology

[0002] In the early days, industrial cleaning relied mainly on manual labor, which was inefficient and posed safety hazards. In the mid-20th century, with increased mechanization, high-pressure water jet cleaning technology began to be widely used, greatly improving cleaning efficiency. Entering the 21st century, industrial cleaning technology has entered a period of rapid development, with automation and intelligentization becoming the main trends.

[0003] Jet cleaning technology, as an important means of maintaining industrial production equipment, has been widely used in the field of industrial cleaning in recent years. Currently, this technology mainly relies on high-pressure water jets or cleaning liquids sprayed through nozzles to remove dirt and impurities. While traditional fixed nozzles are simple to operate, they often have blind spots in cleaning. Furthermore, when processing high-viscosity materials in reaction vessels, large amounts of material adhere to the sides and bottom of the vessel. While high-pressure jet cleaning can remove the adhering substances in small areas through high-pressure rinsing, when the high-viscosity material reaches a certain viscosity and accumulation thickness, simple jet rinsing may not be sufficient to completely remove the residue inside the vessel. Utility Model Content

[0004] To overcome the above-mentioned defects, this application provides a cleaning device for a reaction vessel. The cleaning device uses a scraping unit to pre-clean the residues adhering to the inner wall of the vessel, so that the adhering layer is peeled off in time and sheared and broken by the scraper, thereby improving the waste liquid discharge rate and cleaning efficiency.

[0005] The technical solution adopted by this application to solve its technical problem is:

[0006] A cleaning device for a reaction vessel is installed inside a tank. The cleaning device includes a lifting drive unit, a rotating drive unit, a spraying unit, and a scraping unit. The rotating drive unit includes a first rotating motor and a rotating shaft connected to the first rotating motor. The first rotating motor can drive the rotating shaft to rotate. The lifting drive unit is connected to the rotating shaft and can drive the rotating shaft to move up and down. The scraping unit is used to scrape off residues from the inner wall of the tank. The spraying unit includes a fixing member, a support rod, a distributor, and a nozzle assembly. The fixing member is fixedly installed on the rotating shaft. The first end of the support rod is fixedly installed on the fixing member, and the second end of the support rod is fixedly connected to the distributor. The nozzle assembly is connected to the distributor. The cleaning liquid enters the nozzle assembly through the rotating shaft, the support rod, and the distributor, and is sprayed onto the inner wall of the tank by the nozzle assembly.

[0007] Optionally, a liquid feed pipe is installed inside both the rotating shaft and the support rod, a diversion pipe is provided inside the distributor, and the nozzle assembly includes a connecting pipe and a nozzle head connected to the connecting pipe. The liquid feed pipe, the diversion pipe and the connecting pipe are connected in sequence.

[0008] Optionally, the fixing member is provided with N support rods, which are inclinedly arranged inside the tank, wherein N≥2.

[0009] Optionally, the angle between the central axis of the support rod and the central axis of the tank body is 30° to 65°.

[0010] Optionally, the distributor is provided with M branch pipes, each branch pipe being connected to a connecting pipe, the connecting pipe being a flexible connecting pipe, wherein M≥2.

[0011] Optionally, the tank includes a cylindrical body and a bottom fixedly connected to the cylindrical body, the bottom having an arc-shaped structure, and a discharge pipe installed on the bottom.

[0012] Optionally, the minimum distance between the nozzle head and the inner wall of the bottom is 5 cm, and the shape of the dispenser includes an arc-shaped structure.

[0013] Optionally, the scraping unit includes a second rotary motor, a connecting rod, and a scraper. The scraper is fixedly mounted on the connecting rod, the connecting rod is connected to the second rotary motor, and the second rotary motor can drive the connecting rod to rotate.

[0014] Optionally, the connecting rod is provided with H scrapers, which are attached to the inner sidewall of the tank, wherein H ≥ 2.

[0015] Optionally, the lifting drive unit includes a lifting drive motor and a gear set, the lifting drive motor is connected to the gear set, the gear set meshes with the rotating shaft, and a visual probe is provided inside the tank.

[0016] The beneficial effects of this application are:

[0017] (1) Before the spray cleaning operation begins, the high-viscosity material inside the tank will form an adhesion layer on the inner wall surface of the tank. If the adhesion layer is sprayed directly, the high-viscosity material inside the adhesion layer will hardly be in contact with the cleaning liquid and will form agglomerates due to the surface tension of the surrounding liquid. The agglomerates will be difficult to discharge through the waste liquid pipe, making it difficult to achieve a high degree of cleanliness in the cleaning operation. In this application, the residues adhering to the inner wall of the tank are pre-cleaned by the scraping unit, so that the adhesion layer is peeled off in time and sheared and broken by the scraper. This eliminates the need for cleaning liquid, achieving a water-saving effect. It also facilitates the subsequent spray cleaning steps by ensuring that the residues are fully wetted by the cleaning liquid to form waste liquid without large agglomerates, thereby increasing the waste liquid discharge rate and improving the cleaning efficiency.

[0018] (2) In this application, the first rotary motor can drive the rotary shaft to rotate, and the lifting drive unit can drive the rotary shaft to move up and down in the tank. Therefore, under the action of the first rotary motor and the lifting drive unit, the rotary shaft can drive the nozzle assembly to both rotate and move up and down, thereby ensuring that the nozzle assembly cleans the tank without dead angles and improving the cleaning effect of the tank.

[0026] Example: Figure 1-3As shown, a cleaning device for a reaction vessel is installed inside a tank 100. The cleaning device includes a lifting drive unit 200, a rotation drive unit, a spraying unit 400, and a scraping unit 500. The rotation drive unit includes a first rotary motor and a rotating shaft 300 connected to the first rotary motor. The first rotary motor can drive the rotating shaft 300 to rotate. The lifting drive unit 200 is connected to the rotating shaft 300 and can drive the rotating shaft 300 to perform lifting and lowering movements. The scraping unit 500 is used to scrape off residues from the inner wall of the tank 100. The spraying unit 400 includes a fixing member 410, a support rod 420, a distributor 430, and a nozzle assembly 440. The fixing member 410 is fixedly installed on the rotating shaft 300. The first end of the support rod 420 is fixedly installed on the fixing member 410, and the second end of the support rod 420 is fixedly connected to the distributor 430. The nozzle assembly 440 is connected to the distributor 430. The cleaning fluid enters the nozzle assembly 440 through the rotating shaft 300, the support rod 420, and the distributor 430, and is sprayed onto the inner wall of the tank 100 by the nozzle assembly 440. In this application, a scraping unit 500 is used to pre-clean the residues adhering to the inner wall of the tank 100, so that the adhering layer is peeled off in time and sheared and broken by the scraping unit 500, which is conducive to the full wetting of the residues, improves the waste liquid discharge rate, and thus improves the cleaning efficiency. The first rotary motor can drive the rotary shaft 300 to rotate, and the lifting drive unit 200 can drive the rotary shaft 300 to move up and down inside the tank 100. Therefore, under the action of the first rotary motor and the lifting drive unit 200, the rotary shaft 300 can drive the nozzle assembly 440 to both rotate and move up and down, thereby ensuring that the nozzle assembly 440 cleans the tank 100 without dead angles and improves the cleaning effect of the tank.

[0027] like Figure 1-3 As shown, liquid inlet pipes are installed inside both the rotating shaft 300 and the support rod 420. A diversion pipe 431 is provided inside the distributor 430. The nozzle assembly 440 includes a connecting pipe 441 and a nozzle head 442 connected to the connecting pipe 441. The liquid inlet pipe, the diversion pipe 431, and the connecting pipe 441 are sequentially connected. That is, the cleaning fluid enters the nozzle head 442 through the liquid inlet pipe, the diversion pipe 431, and the connecting pipe 441, and is then sprayed out from the nozzle head 442.

[0028] Optionally, the fixing member 410 is provided with N support rods 420, which are inclinedly arranged inside the tank body 100, wherein N ≥ 2. The number of support rods 420 can be designed as needed. The angle between the central axis of the support rod 420 and the central axis of the tank body 100 is 30° to 65°.

[0029] like Figure 2-3 As shown, the distributor 430 has M branch pipes 431, each branch pipe 431 connected to a connecting pipe 441. The connecting pipe 441 is a flexible connecting pipe, where M ≥ 2. The connecting pipe 441 is made of flexible material, so under the action of external force, the connecting pipe 441 can drive the nozzle head 442 to move. The flexible material of the connecting pipe 441 will produce a small range of movement when affected by rotational external force and its own inertia in the up-and-down movement of the rotating shaft. This further expands the spray range of the nozzle head 442, making the coverage stronger. In addition, the flexible material is more resistant to high-pressure impact, increasing the service life of the spray element.

[0030] like Figure 1 As shown, the tank 100 includes a cylindrical body 110 and a bottom 120 fixedly connected to the cylindrical body 110. The bottom 120 has an arc-shaped structure, and a discharge pipe 140 is installed on the bottom 120.

[0031] The minimum distance between the nozzle head 442 and the inner wall of the bottom 120 is 5cm, and the distributor 430 has an arc-shaped structure. The nozzle head 442 sprays the cleaning fluid at high pressure. If the distance to the inner wall of the tank 100 is too far, the cleaning effect will not be strong enough; if the distance is too close, the nozzle head 442 will be subjected to excessive erosion, shortening its service life and causing wear to the inner wall of the tank. The shape of the distributor 430 is similar to that of the bottom 120 of the tank 100, so that the nozzle head 442 is also arranged in an arc shape on the distributor 430. When the distributor 430 is vertically moved within the tank 100 to the vicinity of the bottom 120, the spray angle and range of the cleaning fluid are conducive to the all-round cleaning of the bottom 120 of the tank 100, preventing the bottom 120 from forming dead corners due to incomplete cleaning and thus affecting subsequent production operations.

[0032] like Figure 1 As shown, the scraping unit 500 includes a second rotary motor, a connecting rod 510, and a scraper 520. The scraper 520 is fixedly installed on the connecting rod 510. The connecting rod 510 is connected to the second rotary motor, and the second rotary motor can drive the connecting rod 510 to rotate.

[0033] The connecting rod 510 is provided with H scrapers 520, which are attached to the inner wall of the tank 100, wherein H ≥ 2. The second rotary motor drives the scrapers 520 to rotate through the connecting rod 510. Since the scrapers 520 are attached to the inner wall of the tank 100, i.e., the inner wall of the cylinder 110, the scrapers 520 can scrape off the attached layer on the inner wall of the cylinder 110.

[0034] Before the spray cleaning operation begins, the high-viscosity material inside tank 100 forms an adhering layer on the inner wall surface of tank 100. If the adhering layer is sprayed directly, the high-viscosity material inside the adhering layer will hardly be in contact with the cleaning liquid and will agglomerate due to the surface tension of the surrounding liquid. The agglomerates will be difficult to discharge through the waste liquid pipe, making it difficult to achieve a high degree of cleanliness. In this application, the scraping unit 500 pre-cleans the residue adhering to the inner wall of tank 100, so that the adhering layer is peeled off in time and sheared and broken by the scraper. This eliminates the need for cleaning liquid, achieving a water-saving effect. It also facilitates the subsequent spray cleaning steps, allowing the residue to be fully wetted by the cleaning liquid to form waste liquid without large agglomerates, improving the waste liquid discharge rate and thus improving the cleaning efficiency.

[0035] The lifting drive unit 200 includes a lifting drive motor and a gear set. The lifting drive motor is connected to the gear set, and the gear set meshes with the rotating shaft 300. Figure 1 As shown, a visual probe 130 is installed inside the tank 100. The lifting drive motor drives the rotating shaft 300 to move linearly through a gear set. Based on the cleaning status inside the tank 100 fed back by the visual probe 130, the spray unit 400 on the rotating shaft 300 is used to spray and clean the residue in a targeted manner. This method is highly flexible and has better water and energy saving effects.

[0036] The operation process of this application includes the following steps:

[0037] Step 1: Scraping the wall: In this embodiment, two scrapers 520 are provided inside the tank 100. The scrapers 520 are attached to the inner wall of the cylinder 110. Driven by the second rotary motor, the scrapers 520 make a circular motion inside the tank 100 to pre-clean the residues attached to the tank 100, so that the attached layer is peeled off in time and cut and broken by the scrapers 520.

[0038] Step 2: Spray cleaning: After the wall scraping is completed, the cleaning fluid enters the liquid feed pipe in the support rod 420 through the liquid feed pipe in the rotating shaft 300, and then enters the spray unit 400. The cleaning fluid enters the connecting pipe 441 through the diversion pipe 431, and finally is sprayed out under high pressure through each nozzle head 442 to spray and rinse the inner wall of the tank 100. The rotating shaft 300 can rotate and lift.

[0039] The automated control process of this application is as follows: A visual probe 130 is located at the top of the tank 100 to monitor the cleaning process inside the tank 100. Valves, pressure sensors, motors, etc., installed on the tank 100 are all connected to the control terminal. Real-time data is fed back to the control terminal to control the operation of the lifting drive motor, thereby controlling the lifting and lowering distance of the rotating shaft 300. The control terminal can adjust various parameters according to actual conditions. For example, when the residual material in the tank 100 is an easily dispersible inorganic metal product, the pressure requirement is generally 80-120 kg / cm³. 2 When the material is an organic product, the viscosity of the slurry also increases accordingly, and the pressure requirement is 50-80 kg / cm³. 2 When the material is an easily cleanable fiber product, the pressure is 20–50 kg / cm². 2 This monitoring and control model can achieve water and energy conservation.

[0040] It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be determined by the appended claims.
