[0010] Beneficial effects

[0011] This invention provides a self-cleaning reactor. It offers the following advantages: This self-cleaning reactor removes dirt residue by having a scraper adhere to the inner wall of the vessel and move up and down reciprocally. Combined with a bottom annular nozzle for real-time rinsing, it enhances cleaning efficiency. A mounting plate supports a threaded rod for stable rotation and axial movement. A second drive motor drives the threaded rod to move an annular magnet up and down, and then a magnetic block drives the entire scraper assembly to move vertically. This achieves fully automated, all-around cleaning of the vessel's interior, completely solving the problems of high labor intensity, low efficiency, and high safety risks associated with traditional manual reactor cleaning, such as contact with corrosive and toxic materials.

[0018] 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.

[0019] Manual cleaning requires operators to enter the reactor and use cleaning tools to wipe it, which is not only labor-intensive and inefficient, but also poses great safety risks to operators when handling reactors containing corrosive, toxic and harmful materials.

[0020] In view of this, the present invention provides a self-cleaning reactor. This self-cleaning reactor removes dirt residue by having a scraper adhere to the inner wall of the tank and move up and down repeatedly. Combined with a bottom annular nozzle for real-time rinsing, it improves cleaning efficiency. A mounting plate supports a threaded rod to achieve stable rotation and axial movement. A second drive motor drives the threaded rod to move the annular magnet up and down, and then the magnetic block drives the scraper assembly to move vertically as a whole. This completes the all-round automated cleaning of the tank's interior, completely solving the problems of high labor intensity, low efficiency, and high safety risks caused by contact with corrosive and toxic materials in traditional manual reactor cleaning.

[0021] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0022] Example 1: By Figure 1-4 It is known that a self-cleaning reactor includes a tank body 1. A first drive motor 2 is fixedly connected to the top of the tank body 1. A rotating rod 3 is fixedly connected to the drive end of the first drive motor 2. The outer wall of the rotating rod 3 is rotatably connected to the tank body 1 through a sealed bearing. Stirring blades 4 are fixedly connected to both sides of the bottom of the rotating rod 3. The self-cleaning reactor also includes a cleaning mechanism 5 and a fixing device 6. The cleaning mechanism 5 is installed on the wall of the tank body 1. The fixing device 6 is installed between the tank body 1 and the cleaning mechanism 5. The cleaning mechanism 5 cleans the inside of the tank body 1. After the cleaning action is completed, the cleaning mechanism 5 can be fixed by the fixing device 6. The model of the first drive motor 2 is Y132S-4. When adding materials to the inside of the reactor, the material conveying pipe is manually connected to the feeding port at the top of the tank body 1 to convey the materials. When it is necessary to discharge materials, the discharge valve at the bottom of the tank body 1 is manually opened to discharge them.

[0023] In the specific implementation process, it is worth noting that the tank 1, as the main structure of the reactor, is used to contain the reaction materials. The first drive motor 2 at the top drives the stirring blade 4 through the rotating rod 3 to achieve mixing and stirring. The cleaning mechanism 5 is installed on the inner wall of the tank 1, including the bottom and both sides, and can automatically clean the residue in the tank 1 after the reaction is completed. The fixing device 6 is installed on the inner wall of the tank 1 and is used to fix it after the cleaning mechanism 5 completes the cleaning task, so as to ensure the structural stability and safety of the reactor during use.

[0024] Furthermore, the cleaning mechanism 5 includes a scraper 51, an annular nozzle 52, a mounting plate 53, a threaded rod 54, a second drive motor 55, a magnetic block 56, an annular magnet 57, and a threaded sleeve 58. The scraper 51 is attached to the lower inner wall of the tank body 1; the annular nozzle 52 is fixedly connected to the bottom of the scraper 51; two mounting plates 53 are provided, respectively fixedly connected to the lower sides of the outer wall of the tank body 1; the threaded rod 54 is rotatably connected to the mounting plate 53 through a bearing; the second drive motor 55 is fixedly connected to the upper side wall of the tank body 1 and drives... The end is fixedly connected to the threaded rod 54; two magnetic blocks 56 are provided, respectively embedded in the outer wall of the annular nozzle 52 on both sides; the annular magnet 57 is sleeved on the outer wall of the tank 1; the threaded sleeve 58 is threadedly connected to the outer wall of the threaded rod 54 and fixed to the outer wall of the annular magnet 57; wherein, the mounting plate 53, the threaded rod 54, the threaded sleeve 58 and the second drive motor 55 cooperate to drive the annular magnet 57 to move vertically, thereby driving the magnetic blocks 56, the scraper 51 and the annular nozzle 52 to move vertically to achieve cleaning inside the tank 1. The cleaning mechanism 5 is constructed by embedding magnetic blocks 56 on both sides of the inner wall of the scraper 51 and cooperating with annular magnets 57. Force is transmitted through magnetic force. This non-contact magnetic transmission method avoids wear and sealing problems that may arise from mechanical connections, making the cleaning mechanism 5 more flexible during vertical movement. It also reduces mechanical interference between the cleaning mechanism 5 and the tank 1, improving the stability of equipment operation to some extent. To prevent limitations in the spray angle and coverage of the annular nozzle 52, which may hinder effective cleaning of corners and other areas of the tank 1, the spray holes on the inner and outer sides of the annular nozzle 52 can be modified and designed by the operator based on actual usage conditions. For example, adjustments can be made to the angle and number of holes to better clean the inner wall of the tank 1 and the outer wall of the stirring blades. Magnetic blocks 56 and annular magnets 57 can be made of high-performance, non-demagnetizing magnetic materials, such as neodymium iron boron magnets. A magnetic monitoring device can be installed on magnetic blocks 56 and annular magnets 57, which will trigger an alarm when the magnetic force drops to a certain level, prompting the replacement of the magnets.

[0025] In the specific implementation process, it is worth noting that the scraper 51 is used to adhere to the lower inner wall of the tank 1. Through its reciprocating up and down movement relative to the inner wall, it can remove the dirt and residues attached to it. The annular nozzle 52 is fixedly connected to the bottom of the scraper 51 and is used to rinse the inner wall of the tank 1 during the movement of the scraper 51, further improving the cleaning effect. The mounting plate 53 is fixedly connected to the lower outer wall of the tank 1 to provide support for the rotation of the threaded rod 54 and ensure its smooth horizontal rotation. The threaded rod 54 is connected to the bearing of the mounting plate 53 to ensure that it can move axially while rotating. The second drive motor 55 drives the threaded rod 54 to rotate. The threaded rod 54 drives the annular magnet 57 on the threaded sleeve 58 to move up and down along the axial direction of the threaded rod 54. Then, through the action of the magnetic block 56, the entire scraper 51 and the annular nozzle 52 are driven to move vertically to achieve comprehensive cleaning of the inside of the tank 1.

[0026] Furthermore, the fixing device 6 includes an electromagnet 61, a first opening 62, an elastic element 63, a positioning pin 64, and a groove 65. Two electromagnets 61 are provided, respectively fixedly connected to the lower sides of the outer wall of the tank 1, and located below the mounting plate 53. Two first openings 62 are provided, respectively opened on the lower sides of the inner wall of the tank 1, and located on the side closest to the electromagnet 61. The elastic element 63 is fixedly connected to the inside of the first opening 62. The positioning pin 64 is fixedly connected to the end of the elastic element 63 and inserted into the inner wall of the first opening 62. The groove 65 is opened on the outer wall of the scraper 51, and its inner wall fits into the positioning pin 64. The electromagnet 61 and the elastic element 62 are connected to the inner wall of the tank 1. The component 63 drives the positioning pin 64 to move within the first opening 62 to fix the groove 65. The contact surface between the positioning pin 64 and the groove 65 is prone to wear due to long-term use, affecting the fixing effect. Hardening treatment can be performed on the surfaces of the positioning pin 64 and the groove 65, such as surface hardening or hard chrome plating, to improve wear resistance. The elastic component 63 works within the first opening 62 for a long time and may be corroded by cleaning fluids or materials, affecting its elastic performance. It is necessary for the staff to determine whether to wrap the elastic component 63 with a corrosion-resistant protective sleeve, such as a rubber sleeve or a plastic sleeve, based on the on-site usage. The condition of the elastic component 63 should be checked regularly, and aged or damaged elastic components 63 should be replaced in a timely manner.

[0027] In the specific implementation process, it is worth noting that the electromagnet 61 is used to fix the lower sides of the outer wall of the tank 1, providing magnetic force to the positioning pins 64 on the scraper 51 to ensure its stable fixation. The first opening 62 is used to install the elastic element 63, and is opened on the lower sides of the inner wall of the tank 1, close to the electromagnet 61, providing a space for the elastic element 63 and the positioning pins 64 to move. The elastic element 63 is fixedly connected in the first opening 62 and can be pressed into the first opening 62 when it is attracted by the electromagnet 61. Under the action of force, it remains in a pop-out state. The positioning pin 64 is fixedly connected to the end of the elastic element 63 and has a certain elasticity and magnetic attraction. It can be held in the groove 65 under the elastic force of the elastic element 63 to ensure the stable position of the scraper 51. The groove 65 is opened on both sides of the outer wall of the scraper 51 and fits with the positioning pin 64 to receive the positioning pin 64. Through the cooperation of the magnetic force of the electromagnet 61 and the elastic force of the elastic element 63, the positioning pin 64 can be accurately fixed in the groove 65, thereby realizing the accurate fixation of the scraper 51 and the tank 1.

[0028] Example 2: From Figure 1-4 It can be seen that the bottom of the tank 1 is fixedly connected to the box 7. The bottom of the tank 1 and the top of the box 7 are both provided with a second opening 11. The hose 8 passes through the box 7 and the second opening 11 in sequence and is connected to the bottom of the annular nozzle 52. The end of the hose 8 extends to the outside of the box 7. The second opening 11 can allow the wastewater generated inside the tank 1 to flow into the box 7. An external water supply device can be installed at the position where the hose 8 extends to the outside of the box 7.

[0029] In the specific implementation process, it is worth noting that the top of the box 7 and the bottom of the tank 1 are provided with a second opening 11, which allows the hose 8 to pass through. One end of the hose 8 is connected to the bottom of the annular nozzle 52, while the other end passes through the box 7 and connects to the external cleaning fluid supply equipment. The function of the hose 8 is to transmit liquid so that it can be sprayed evenly from the annular nozzle 52. The annular nozzle 52 is used to spray the liquid transmitted from the hose 8 evenly, so as to achieve precise distribution of liquid and improve spraying efficiency and uniformity.

[0030] Furthermore, a sealing gasket 10 is fixedly connected to the bottom of the annular nozzle 52 and sleeved on the outer wall of the hose 8. The sealing gasket 10 is fixedly connected to the outer wall of the hose 8 and fits against the bottom of the inner wall of the tank 1. A valve 9 is connected to the bottom of the side wall of the box 7.

[0031] In the specific implementation process, it is worth noting that the sealing gasket 10 is fixedly connected to the bottom of the annular nozzle 52, which ensures that the second opening 11 will not leak when the annular nozzle 52 returns to its original position after working. The tight fit with the bottom of the inner wall of the tank 1 further improves the sealing performance and ensures the sealing effect when the tank 1 is reacting normally. The bottom of the side wall of the box 7 is connected to the outside through the valve 9, and the discharge of wastewater can be controlled by opening or closing the valve 9.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
