[0018] As a preferred solution, further, the cleaning mechanism 9 includes a cylinder 91 vertically installed at the center of the base 81, and the inner cavity of the cylinder 91 is cylindrical, and the inner wall of the cylinder 91 is provided with a limit groove 95 from top to bottom, and an inner tube 92 is installed at the center of the top of the cylinder 91, and the top of the inner tube 92 is connected to the high-pressure pump 6 through a water pipe, and hydraulic cylinders 93 electrically connected to the controller 4 are installed on both sides of the upper surface of the cylinder 91, and a support seat is installed at the output end of the hydraulic cylinder 93 94, the outer wall of the inner tube 92 is sleeved with an outer tube 96, and the outer tube 96 can be raised or lowered under the drive of the hydraulic cylinder 93. A limit rod 97 is installed on the top of the outer wall of the outer tube 96, which is plugged into the inner cavity of the limit groove 95. The limit groove 95 is spirally distributed from top to bottom on the inner wall of the cylinder 91. When the outer tube 96 moves up and down, the limit rod 97 slides along the limit groove 95, and the curved surface of the limit groove 95 affects the outer tube 96 to rotate. A water distributor 98 is installed at the bottom of the outer tube 96. A telescopic rod 99 is installed at the bottom of both sides of 98, and a mounting plate 910 is vertically installed outside the telescopic rod 99. A telescopic connecting rod 911 is connected between the water distributor 98 and the mounting plate 910 through a pin shaft. A cylinder 912 electrically connected to the controller 4 is installed on the top of both sides of the water distributor 98. The output end of the cylinder 912 is connected to the center of the telescopic connecting rod 911 through a pin shaft. Under the traction of the cylinder 912, the telescopic connecting rod 911 can be extended or shortened, thereby making the two mounting The plate 910 moves inward or outward at the same time, a nozzle 913 is installed at the bottom of the mounting plate 910, the nozzle 913 is connected to the bottom of the water distributor 98 through a water pipe, a guide wheel 914 is installed in the middle of the outer side of the mounting plate 910, the guide wheel 914 protrudes outward compared to the nozzle 913, after entering the reactor, the guide wheel 914 is allowed to contact the inner wall of the reactor first, and the spraying space is reserved for the nozzle 913, and a protective layer detection component 915 is installed on the top of the outer side of the mounting plate 910.

[0019] As a preferred solution, further, the protective layer detection component 915 includes a box body 9151 installed horizontally at the top of the outer side of the mounting plate 910, two travel switches 9152 arranged front and back are installed on the left side of the inner cavity of the box body 9151, and the travel switch 9152 is electrically connected to the controller 4, and two guide rods 9153 are installed in the inner cavity of the box body 9151 along the front and rear directions. The front and rear sides of the outer wall of the guide rod 9153 are respectively sleeved with a moving plate 9154 and a spring 9155. Under the elastic force of the spring 9155, the moving plate 9154 is pushed forward. A bump 9156 is installed at the front end of the left side wall of the moving plate 9154. The front and rear sides of the bump 9156 are inclined. As the moving plate 91 54 moves forward and backward, so that the inclined surface of the protrusion 9156 can allow the travel switch 9152 to roll smoothly between the protrusion 9156 and the left side wall of the movable plate 9154, and the protrusion 9156 triggers the travel switch 9152. A guide groove 9157 is provided on the upper surface of the movable plate 9154, and a telescopic roller 9158 that can slide left and right is inserted into the right side wall of the box body 9151. A guide column 9159 inserted into the guide groove 9157 is installed on the left end of the telescopic roller 9158. The guide groove 9157 is obliquely set on the upper surface of the movable plate 9154. As the movable plate 9154 moves forward, the guide groove 9157 squeezes the guide column 9159 to the right, thereby causing the telescopic roller 9158 to move right.

[0020] Working principle: Step 1: lower the cleaning mechanism 9 into the reactor, screw the adjusting bolt 82, move the clamping plate 83 inward, clamp the clamping plate 83 at the opening of the reactor, and position the cleaning mechanism 9; Step 2: The cylinder 912 is started by the controller 4, and the cylinder 912 drives the telescopic connecting rod 911 to extend. Under the condition that the telescopic rod 99 limits the mounting plate 910, the telescopic connecting rod 911 pushes the mounting plate 910 to move outward until the guide wheel 914 contacts the inner wall of the reactor, so that the nozzle 913 reaches the specified position. Step 3: The telescopic roller 9158 is squeezed, so that the guide column 9159 pushes the guide groove 9157 inward, and the movable plate 9154 moves backward along the outer wall of the guide rod 9153, so that the travel switch 9152 at the rear side is triggered by the protrusion 9156, and an electrical signal is fed back to the controller 4. The controller 4 controls the left warning light 5 to emit green light. The current state indicates that the lining on the inner wall of the reactor is not damaged; Step 4: The high-pressure pump 6, the motor 7 and the hydraulic cylinder 93 are started by the controller 4. The high-pressure pump 6 is driven by the motor 7 to operate. The high-pressure pump 6 extracts the cleaning liquid from the water tank 2, pressurizes the cleaning liquid and delivers it to the inner tube 92. After passing through the outer tube 96, the water distributor 98 diverts the cleaning liquid, and after diversion, it is delivered to the nozzle 913. The nozzle 913 sprays water to the lining of the reactor, and the impact force of the water flow washes the lining of the reactor; The hydraulic cylinder 93 drives the support seat 94 to descend, and the limiting rod 97 slides along the limiting groove 95. Since the limiting groove 95 is spiral, the limiting rod 97 drives the outer tube 96 to descend and rotate at the same time. Therefore, the guide wheel 914 and the telescopic roller 9158 roll along the inner lining of the reactor, and the nozzle 913 rotates and descends to fully clean the reactor. Step five, once the telescopic roller 9158 passes through the broken reactor lining, the telescopic roller 9158 moves outward under the influence of the elastic force of the spring 9155, and the elastic force of the spring 9155 pushes the movable plate 9154 forward. The travel switch 9152 on the front side is squeezed by the protrusion 9156 and triggered, and an electrical signal is fed back to the controller 4. The warning light 5 on the right emits red light, indicating that the reactor lining is damaged, thereby realizing the quality inspection of the reactor.

[0021] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
