Description

Technical Field

[0001] The invention relates to the technical field of cleaning and processing of anti-corrosion storage tanks, and in particular to a liner-type anti-corrosion storage tank processing device. Background Art

[0002] A lined anti-corrosion storage tank is a chemical pressure vessel used to store corrosive substances. It has a structure with an inner lining anti-corrosion layer. The inner lining anti-corrosion layer is usually made of corrosion-resistant fiberglass, polyethylene, polypropylene and other materials, and has good corrosion resistance. The tank body is usually made of carbon steel or stainless steel. The tank body is lined with an anti-corrosion layer. During use, the inside of the tank body often needs to be cleaned to prevent the residue of the stored liquid from affecting the quality of the tank body and the quality of the subsequent stored liquid.

[0003] At present, the cleaning of the inside of the tank is carried out by moving the nozzle or placing the three-dimensional nozzle at a fixed point. However, the cleaning time is still relatively long and the cleaning efficiency is low. In addition, for vertical tanks with openings at the ends, the nozzle needs to move a long distance during the cleaning process. As the nozzle goes deeper, the stability of the nozzle will decrease, which will affect the cleaning effect of the nozzle. Summary of the Invention

[0007] In one possible implementation, the tensioning control component includes a unified gear ring, a support rod, and a bidirectional screw threaded with a moving block. The end of the bidirectional screw is fixedly connected to a gear that meshes with the unified gear ring. The unified gear ring is rotatably connected to the outer ring seat, and the bidirectional screw is rotatably connected to the inner column seat. The support rod is symmetrically arranged and the two ends are respectively hinged to the inner support member and the moving block.

DETAILED DESCRIPTION

[0022] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described below, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] See also Figure 1 and Figure 3 A liner-type anti-corrosion storage tank processing device includes a feeding mechanism 2 provided with a rotating end 1 and a cleaning mechanism 3 provided on the rotating end 1, such as Figure 2 As shown, the feeding mechanism 2 sends the cleaning mechanism 3 into the tank body through the rotating end 1, and the rotation axis of the rotating end 1 coincides with the axis of the tank body. Then the rotating end 1 drives the cleaning mechanism 3 to rotate one circle to quickly complete the cleaning of the inside of the tank body, and the rotating end 1 only needs to extend into the half of the inside of the tank body at most to complete the cleaning, which provides a stable support point for the cleaning mechanism 3, effectively improves the stability of the cleaning process of the cleaning mechanism 3, and overall improves the efficiency and effect of tank cleaning.

[0024] See Figure 2-4 The cleaning mechanism 3 includes a cleaning head 31 and a control assembly 32. The control assembly 32 includes a main bracket 321 that is limited and rotatably connected to the rotating end 1, and the rotation connection point is located in the middle area of ​​the main bracket 321. Both ends of the main bracket 321 are limited and hinged with a mounting bracket 322 for mounting the cleaning head 31. The other end of the mounting bracket 322 is limited and hinged with a sub-bracket 323. A slider 327 is provided between the other end of the sub-bracket 323 and the main bracket 321. Figure 4As shown, the slider 327 is limited and slidably connected to the main bracket 321, and the auxiliary bracket 323 is limited and hinged on the slider 327, as shown in FIG. Figure 2 As shown, during the cleaning process, the main bracket 321, the mounting bracket 322 and the auxiliary bracket 323 are combined to form two triangular frames, the frames are located on both sides of the main bracket 321, and the mounting bracket 322 is parallel to the axis of the tank body. The cleaning heads 31 are evenly distributed along the mounting bracket 322, and the rotation of the rotating end 1 synchronously drives the two triangular frames to rotate, and then the inner wall of the tank body is cleaned by the cleaning head 31. In the process of the frame rotating with the rotating end 1, the cleaning head 31 always maintains a stable position relationship with the inner wall of the tank body, thereby ensuring the stability of the cleaning process.

[0025] See Figure 2-4 The upper limit of the main bracket 321 is hinged with a control frame 324, and the end of the feeding mechanism 2 close to the rotating end 1 is rotatably provided with a rotating ring 325. The outer ring surface of the rotating ring 325 is slidingly provided with a connecting block 326. The control frame 324 and the connecting block 326 are limited and hinged. The main bracket 321 is a rectangular frame with a middle hole. The auxiliary bracket 323 and the mounting bracket 322 can be stored in the middle area of ​​the main bracket 321. When cleaning, the sliding connecting block 326 enables the control frame 324 to support the main bracket 321 to rotate a certain angle. At the same time, the sliding slider 327 enables the auxiliary bracket 323 to support the mounting bracket 322 to rotate until the mounting bracket 322 is parallel to the axis of the tank body. After that, The connecting block 326 and the slider 327 stop sliding and remain in the current position, respectively locking the main bracket 321 and the mounting bracket 322 in the current position state. At the same time, under the connection restriction of the control frame 324, the stability of the main bracket 321 is further improved, and the stability of the cleaning work is correspondingly improved. When the cleaning is completed, the connecting block 326 and the slider 327 are reset, and the auxiliary bracket 323 and the mounting bracket 322 are stored in the middle area of ​​the main bracket 321. The main bracket 321 is reset from a state with a larger tilt angle to a state with a smaller tilt angle, which is convenient for it to be removed from the tank mouth, thereby correspondingly improving the convenience of using the present invention.

[0026] See Figure 2 、 Figure 4 and Figure 5 , and the two ends of the main bracket 321 close to the bottom wall of the tank body and the filling port are limited and hinged with auxiliary brackets 328 for installing the cleaning head 31. The auxiliary bracket 328 corresponds to the mounting bracket 322 one by one and a gear rack conversion component 6 is connected between the two. Figure 5As shown, the rack and pinion conversion assembly 6 includes an arcuate rack 61 and a conversion gear set 62. There are two arcuate racks 61, each connected to the auxiliary frame 328 and the mounting frame 322. The conversion gear set 62 includes two coaxially connected gears. The arcuate racks 61 mesh with the gears in a one-to-one correspondence. When the mounting frame 322 rotates, the meshing between the arcuate racks 61 and the gears synchronously drives the auxiliary frame 328 to rotate in the opposite direction. When the mounting frame 322 rotates to a horizontal position, the auxiliary frame 328 rotates to a vertical position.

[0027] See Figure 1 、 Figure 2 、 Figure 6 and Figure 7 The feeding mechanism 2 includes a fixed seat 22 provided with a centering component 21, and the fixed seat 22 includes an outer ring seat 221 and an inner column seat 223 with a sliding channel 222. The inner column seat 223 is fixedly sleeved with the outer ring seat 221, and the middle part of the inner column seat 223 is horizontally slidably provided with a feeding piece 23. The centering component 21 includes an outer clamping piece 211 arranged along the circumference of the outer ring seat 221 and an inner stretching piece 212 arranged along the circumference of the inner column seat 223. The inner stretching piece 212 is radially slidably connected to the inner column seat 223 along the inner column seat 223, and the end of the inner stretching piece 212 extending into the interior of the tank body is inclined away from the axis of the tank body. A tensioning control piece 213 for stretching the inner stretching piece 212 is provided on the fixed seat 22. Figure 6 and Figure 7 As shown, there are three internal support members 212 and they are arranged on the inner column seat 223 avoiding the sliding channel 222. During the cleaning process, one end of the inner column seat 223 is inserted into the interior of the tank body. At this time, the inclined end of the internal support member 212 is located in the tank body and at the position of the tank mouth. The tensioning control member 213 causes the internal support member 212 to slide outward synchronously and rest against the inner wall of the tank mouth. At this time, the inclined part of the internal support member 212 is just stuck at the tank mouth from the inside, and the position of the inner column seat 223 is adjusted as a whole, so that the axis of the inner column seat 223 coincides with the axis of the tank body, and at the same time, the inner column seat 223 is firmly stuck on the tank mouth, providing a stable support force for the cleaning mechanism 3 and improving the stability of the working process of the cleaning mechanism 3.

[0028] See Figure 6 and Figure 7 The tensioning control member 213 includes a unified gear ring 2131, a support rod 2132, and a bidirectional screw 2134 threadedly connected to a moving block 2133. The end of the bidirectional screw 2134 is fixedly connected to a gear that meshes with the unified gear ring 2131. The unified gear ring 2131 is rotatably connected to the outer ring seat 221, and the bidirectional screw 2134 is rotatably connected to the inner column seat 223. Figure 6As shown, the support rod 2132 is symmetrically arranged on both sides and is hinged to the inner support member 212 and the moving block 2133 at both ends. The moving block 2133 corresponds to the support rod 2132 one by one and is slidably connected to the inner column seat 223. In the process of moving the inner support member 212, it is only necessary to rotate the unified gear ring 2131, as shown in FIG. Figure 7 As shown, the unified gear ring 2131 drives the bidirectional screw 2134 to rotate. At this time, the moving block 2133 moves in the opposite direction synchronously, and drives the inner support member 212 to slide radially outward along the inner column seat 223 through the support rod 2132. The setting of this structure can improve the force balance of the inner support member 212, thereby improving the stability of the inner column seat 223. The unified drive ring 2131 can be rotated manually or an external drive control of the unified drive ring 2131 with a gear member sleeved on the drive shaft can be set. During the driving process, the gear member is engaged and connected with the unified drive ring 2131, and the rotation of the gear member drives the unified drive ring 2131 to rotate.

[0029] See Figure 2 and Figure 3 The feeding member 23 is a sliding column, which slides along the axial direction of the inner column seat 223. The rotating ring 325 is rotatably sleeved on the sliding column. The rotating end 1 is embedded and rotatably connected to the end of the sliding column, and the end of the rotating end 1 close to the rotating ring 325 is connected to an extension shaft 4. The extension shaft 4 is rotatably inserted in the sliding column and can pass through the sliding column to extend to the outside of the tank and then connect to the driving source, or an external driving source is installed in the sliding column to drive the extension shaft 4. A connecting member 7 with a synchronous gear ring is fixedly sleeved on the annular surface of the extension shaft 4. A synchronous gear ring assembly 5 is provided between the extension shaft 4 and the rotating ring 325. The synchronous gear ring assembly 5 is used to control the synchronous rotation of the rotating ring 325 and the rotating end 1. Figure 3 As shown, the synchronous gear ring assembly 5 includes a ring gear 51 and a synchronous gear 52. The diameter, size and structure of the ring gear 51 and the synchronous ring gear are exactly the same and the two are symmetrically distributed. At the same time, the ring gear 51 is fixedly connected to the rotating ring 325, and the synchronous gear 52 is engaged with the synchronous ring gear and the ring gear 51 at the same time. During the rotation of the rotating end 1, the synchronous gear ring assembly 5 on the extension shaft 4 drives the rotating ring 325 to rotate synchronously with the rotating end 1, further improving the stability of the cleaning process. Among them, the water supply system of the cleaning head 31 can be achieved by setting an internal water supply pipe for the cleaning head 21 on the mounting frame 322, setting an external water supply pipe on the sliding column, and sealing the aforementioned internal water supply pipe and the external water supply pipe through a flexible connecting pipe to supply water to the cloth cleaning head 31.
