The cleaner includes a water inlet, a high-pressure water pump, and a nozzle. However, this device still has the following problems:

[0004] 1. When encountering some sticky impurities, it is difficult to remove them by water flow alone. To completely remove them, repeated and long-term rinsing is required, which is inefficient.

[0005] 2. The cleaning device is always placed inside the reactor. When the reaction is taking place in the reactor, it can easily affect the mixing efficiency of the reactants. In addition, the cleaning device will also have residual reactants adhering to it, which will affect its subsequent use. Utility Model Content

[0006] In order to solve the problems existing in the prior art, a reactor cleaning device is provided to address the problems mentioned in the background.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] This utility model proposes a reactor cleaning device, including a base disposed on the reactor. The base is rotatably connected to a splined shaft, and the splined shaft is connected to a drive assembly.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model is equipped with a splined shaft, which can drive the brush on the slide to rotate, thereby rotating and brushing the inner wall of the reactor. At the same time, the screw drives the slide to move along the axis of the splined shaft, so that the brush can clean all heights of the inner wall of the reactor. The brush can both rotate around the splined shaft and slide along the axis of the splined shaft, so that the cleaning trajectory of the brush on the inner wall of the cylinder is a spiral, which combines linear motion and single rotational cleaning along the axis, thus improving cleaning efficiency.

[0020] 2. This utility model is equipped with rollers. When the slide seat drives the rollers to rotate along the cylinder wall, the rollers can drive the brush to rotate.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] like Figures 1-4As shown, this embodiment proposes a reactor cleaning device, including a base 1, which is disposed on a reactor 20. The base 1 is rotatably connected to a splined shaft 2, which is connected to a drive assembly. A slide block 3 is slidably sleeved on the splined shaft 2, and a screw 4 is threadedly connected to the slide block 3. When the screw 4 rotates, it can drive the slide block 3 to slide along the splined shaft 2. Several brushes 6 are connected to the slide block 3, and the brushes 6 are in contact with the inner wall of the reactor 20.

[0031] A bearing is fixedly sleeved on the upper end of the spline shaft 2, and is rotatably connected to the base 1 through the bearing. The drive assembly can drive the spline shaft 2 to rotate. When the spline shaft 2 rotates, it can drive the brush 6 to move in a circular direction along the inner wall of the reactor 20, so that the brush 6 cleans the inner wall. At the same time, by rotating the screw 4, the slide 3 moves along the axis of the spline shaft 2 to clean the inner wall in the vertical direction. The cleaning trajectory of the brush on the inner wall is a spiral, which combines linear motion and single rotation along the axis, thus improving the cleaning efficiency.

[0032] The reactor 20 is equipped with an end cap 19, and the base 1 is detachably connected to the end cap 19 via a disassembly bolt 21. The disassembly bolt 21 allows for the easy removal of the cleaning device from the reactor after the inner wall of the reactor 20 has been cleaned, preventing any impact on subsequent reactions. Removing the cleaning device also facilitates the cleaning of any remaining impurities, which is beneficial for future use.

[0033] The end cap 19 has a stepped hole, and the base 1 is placed on the step of the stepped hole.

[0034] It also includes several support rods 5, one end of which is rotatably connected to the slide block 3 via a rotating shaft. At least one support rod 5 is connected to a brush 6 at the other end. A turbine 10 is coaxially fixed to the rotating shaft. A worm gear 11 is rotatably connected to the slide block 3. The worm gear 11 cooperates with the turbine 10.

[0035] By rotating the worm gear 11, the worm gear 11 drives the turbine 10 to rotate. The turbine 10 drives the support rod 5 to rotate through the rotating shaft, thereby realizing the storage and unfolding of the support rod 5, which is convenient to take out from the reactor 20 and convenient for subsequent storage. At the same time, the self-locking of the turbine worm gear can ensure the stability of the support rod 5 when cleaning the inner wall after it is unfolded.

[0036] At least one support rod 5 has a side plate 12 on one side, a brush 6 is rotatably mounted on the side plate 12, and a roller 13 is coaxially fixed to the brush 6. The roller 13 can roll along the inner wall of the reactor 20.

[0037] When the spline shaft 2 drives the slide 3 to rotate, the slide 3 drives the support rod 5 to rotate, and the support rod 5 drives the roller 13 to roll along the inner wall of the reactor 20. Since the roller 13 is coaxially fixed with the brush 6, the roller 13 will drive the brush 6 to rotate, so that the brush 6 can brush the same position of the cylinder wall multiple times in a unit time, thereby improving the cleaning efficiency.

[0038] The axis of the roller 13 is at a certain angle to the axis of the spline shaft 2, which reduces the friction between the roller 13 and the inner wall when the roller 13 follows the slide block 3 spiraling downward or upward.

[0039] A spring 14 is fixed to one end of the support rod 5, and the side plate 12 is fixed to the support rod 5 by the spring 14.

[0040] When the support rod 5 is extended, the brush 6 comes into contact with the inner wall. At this time, the spring 14 is in a compressed state, which can apply pressure to the brush 6, making the brush 6 fit more tightly with the inner wall. This helps to avoid gaps between the brush 6 and the inner wall and improves the cleaning level.

[0041] One of the support rods 5 is fixedly connected to a scraper 15 via a spring 14.

[0042] The scraper 15 contacts the inner wall under the elastic force of the spring 14. As the slide 3 rotates, the scraper can scrape the inner wall and clean the residue after the brush 6 has cleaned it, further improving the cleanliness of the inner wall.

[0043] A connecting rod 7 is fixed on one side of the spline shaft 2. The connecting rod 7 is rotatably connected to a small gear 8. The small gear 8 is coaxially fixed with the screw 4. A gear ring 9 is fixed on the base 1. The gear ring 9 meshes with the small gear 8.

[0044] Since the gear ring 9 and the base 1 are fixed, when the spline shaft 2 drives the screw 4 to revolve through the connecting rod 7, the gear ring 9 drives the pinion 8 to rotate, which in turn drives the screw 4 to rotate. The screw 4 will then rotate relative to the slide 3, and the screw 4 will drive the slide 3 to move up and down along the spline shaft 2 through the thread.

[0045] The drive assembly includes a motor 16, which is directly connected to a drive wheel 17. A splined shaft 2 is fixedly connected to a driven wheel 18, and the drive wheel 17 meshes with the driven wheel 18.

[0046] The motor 16 is fixed on the base 1.

[0047] The lower end of the splined shaft 2 is rotatably connected to a rotating base 22, which abuts against the bottom of the reactor 20. A limit switch 23 is fixedly connected to the rotating base 22, and the limit switch 23 is electrically connected to the motor 16.

[0048] Limit switch 23 is specifically a push-button spring switch, which typically consists of a push button, a spring, a mounting base, and conductive contacts. The push button is usually made of plastic or metal and has a certain pressing performance and mechanical strength. The spring's function is to allow the button to automatically return to its original position and ensure the elasticity of the press. The mounting base is used to fix the button and spring, ensuring that their positions do not change. The conductive contacts are the key part connecting the circuit; pressing the button connects or disconnects the circuit through the contacts, thus realizing the switch function.

[0049] When the slide 3 moves to the lower end, it will touch the limit switch 23. When the limit switch 23 is pressed, the motor 16 will be de-energized, the entire device will stop moving, and then the motor 16 will be restarted to reverse the motor 16 and make the slide 3 rise again to perform a second cleaning of the inner wall.

[0050] At least one adjustment port is provided on the base 1 for easy adjustment, and a piston 24 slides inside the adjustment port.

[0051] Pulling out piston 24 exposes the adjustment port, allowing observation of the device's operation; and after installing base 1, adjusting worm gear 11 allows for the retraction and extension of support rod 5.

[0052] The spline shaft 2 is hollow inside and connected to a water pipe. The water pipe is connected to a water tank. Spray nozzles 25 are installed on the circumference of the rotating base 22 and the bottom of the base 1. The spray nozzles 25 at the bottom of the base 1 can spray water onto the inner wall to further clean the impurities on the inner wall. The spray nozzles 25 around the rotating base 22 can rinse the impurities accumulated at the bottom of the reactor 20, so that they can flow out of the outlet at the bottom of the reactor 20 more quickly.

[0053] Specific work process:

[0054] S1: Remove the pre-set cover on the stepped hole of the lower end cover 19, place the base 1 in the stepped hole, so that the base 1 and the end cover 19 are closed. At the same time, the lower end of the spline shaft 2 abuts against the bottom of the reactor 20 through the swivel 22. Then, fix the base 1 and the end cover 19 by removing the bolt 21.

[0055] S2: Pull out piston 24 to open the adjustment port. The operator rotates worm gear 11, which drives turbine 10 to rotate. Turbine 10 drives support rod 5 to rotate, so that support rod 5 is unfolded from the retracted state. The brush 6 and scraper 15 at the end of support rod 5 contact the inner wall of reactor 20. At the same time, spring 14 uses its elasticity to press brush 6 and scraper 15 against the inner wall of reactor 20.

[0056] S3: Start motor 16, so that motor 16 drives the driven wheel 18, which is fixed coaxially with spline shaft 2, to rotate through drive wheel 17. Driven wheel 18 drives spline shaft 2 to rotate. Spline shaft 2 drives brush 6 and scraper 15 to rotate along the inner wall of reactor 20 through slide 3 to clean the inner wall. At the same time, when slide 3 rotates, gear ring 9 drives pinion 8 and screw 4 to rotate, driving slide 3 to slide along the axis of spline shaft 2.

[0057] S4: Roller 13 abuts against the inner wall of the reactor under the action of spring 14. As slide 3 rotates, roller 13 rolls along the inner wall, thereby driving brush 6 to rotate. Brush 6 rotates while following slide 3, thus improving cleaning efficiency.

[0058] S5: After reaching the bottom, slide 3 presses the limit switch 23, and motor 16 stops rotating. Then, the staff restarts motor 16 to reverse the motor and move slide 3 back to the top to complete the cleaning. At this time, pull out piston 24, rotate worm gear 11 to make support rod 5 rotate around slide 3, and store support rod 5. Then remove disassembly bolt 21 to take out the entire cleaning device.

[0059] In S3-S5, after starting motor 16, the water pump in the external water tank works simultaneously, delivering the water in the water tank to the nozzle 25 position, so that the nozzle can further clean the inner wall and make the impurities flow out faster with the water flow.

[0060] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
