Description

Technical Field

[0001] This utility model relates to the field of cooling pipe removal technology, specifically a device for removing cooling pipes inside a water tank. Background Technology

[0002] In the soda ash production process, the calcination of heavy soda ash requires carbonation towers and absorption towers. The water tanks inside the carbonation towers and absorption towers are used for cooling. The cooling pipes inside the water tanks are generally made of titanium. After long-term operation, scale and dirt will accumulate on the cooling pipes. These impurities will reduce cooling efficiency and even cause equipment blockage. Therefore, regular cleaning is required to restore the heat exchange performance of the cooling pipes. During cleaning, the cooling pipes need to be removed from the water tank one by one. In the existing technology, special hammering tools need to be made, and the cooling pipes are removed manually by forcefully hammering with the hammering tools. The removal efficiency is low, the risk factor is high, and it is easy to damage the pipe openings, increasing maintenance costs. Utility Model Content

It includes a slide rail arranged along the length of the water tank, a support frame slidably connected to the slide rail, a bracket that can slide up and down along the support frame, and a pushing mechanism that can push the cooling pipes out laterally on the bracket. It also includes a traction mechanism for driving the bracket to slide up and down.

[0005] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are: The jacking mechanism can directly push the water-cooling pipe out laterally. The height of the jacking mechanism can be adjusted by sliding the bracket, and the horizontal position of the jacking mechanism can be adjusted by the slide rail. This avoids manual hammering, reduces the risk factor, improves the efficiency of pipe dismantling, and prevents damage to the cooling pipe opening.

[0006] As a preferred embodiment, a further technical solution of this utility model is: Preferably, there are two slide rails, which are installed on the upper and lower edges of the water tank respectively. The slide rails are made of angle steel, and the vertical side plates of the slide rails are bolted to the water tank body. The installation and disassembly are simple, economical and practical.

The lower mounting seat is equipped with a second guide wheel, which is located on the outside of the vertical side plate of the lower slide rail.

[0008] Preferably, the mounting base has a C-shaped structure, including two horizontal plates and one vertical plate. One of the horizontal plates is bolted to the support frame, and the two horizontal plates are set parallel to the horizontal side plate and are located on the upper and lower sides of the horizontal side plate, respectively.

[0009] Preferably, the pushing mechanism includes a hydraulic cylinder and a pusher fitting connected to the output end of the hydraulic cylinder.

[0016] like Figures 1 to 3 As shown, this embodiment provides a cooling pipe removal device for a water tank, which is installed on one side of the water tank 1. It includes a slide rail 3 arranged along the length of the water tank 1, a support frame 4 slidably connected to the slide rail 3, a bracket 5 that can slide up and down along the support frame 4, and a pushing mechanism 6 that can push the cooling pipe 2 laterally out of the bracket 5. It also includes a traction mechanism for driving the bracket 5 to slide up and down. Two slide rails 3 are provided, respectively installed on the upper and lower edges of the water tank 1. The slide rails 3 are made of angle steel, and the vertical side plates of the slide rails 3 are bolted to the body of the water tank 1. The support frame 4 is made of channel steel, and the bracket 5 has sliding grooves 501 on both sides, through which the bracket 5 is slidably connected to the support frame.

[0017] Two mounting seats 7 are provided on the support frame 4 at the positions corresponding to the two slide rails 3. The upper mounting seat 7 is equipped with a traveling wheel 8 and a first guide wheel 9. The traveling wheel 8 travels on the horizontal side plate of the upper slide rail 3, and the first guide wheel 9 travels on the outside of the vertical side plate of the upper slide rail 3. The lower mounting seat 7 is equipped with a second guide wheel 10, and the second guide wheel 10 travels on the outside of the vertical side plate of the lower slide rail 3.

[0018] like Figure 2 , Figure 3 The mounting base 7 has a C-shaped structure, including two horizontal plates and one vertical plate. One of the horizontal plates is bolted to the support frame 4. The two horizontal plates are set parallel to the horizontal side plate and are located on the upper and lower sides of the horizontal side plate respectively.

[0019] In use, first install the slide rail 3 on the water tank 1, then assemble the mounting base 7 on the upper and lower slide rails 3, and connect and fix the support frame 4 to the mounting base 7; manually push the support frame 4 to slide along the slide rail 3 to adjust the horizontal position of the jacking mechanism 6; drive the bracket 5 to slide up and down along the support frame 4 through the traction mechanism, thereby driving the jacking mechanism 6 to move up and down, realizing the adjustment of the height of the jacking mechanism 6, and thus enabling the side push of the cooling pipes 2 at each position; no need for manual hammering, reducing the risk factor, improving the efficiency of pipe disassembly, and avoiding damage to the pipe openings of the cooling pipes 2.

[0020] The jacking mechanism 6 includes a hydraulic cylinder 601 and a push tube connected to the output end of the hydraulic cylinder 601. The hydraulic cylinder 601 can also be replaced by an electric push rod, hydraulic push rod, or other devices known to those skilled in the art.

[0021] As one embodiment, the front end of the pusher is the insertion end and the rear end is the connection end; correspondingly, the output end of the hydraulic cylinder 601 has a flange, and the connection end is connected to the flange of the output end of the hydraulic cylinder 601. The outer diameter of the insertion end is adapted to the inner diameter of the cooling pipe 2, and its diameter is greater than or equal to the outer diameter of the cooling pipe 2; the cooling pipe 2 is pushed out laterally by the pusher, and the size of the pusher can be changed according to the size of the cooling pipe 2, which improves the versatility of the device.

[0022] In another embodiment, the front end of the pusher is a first insertion end, the outer diameter of which is adapted to the inner diameter of the cooling pipe 2. The middle part is a pushing part, the diameter of which is greater than or equal to the outer diameter of the cooling pipe 2. The rear end is a second insertion end. Correspondingly, the output end of the hydraulic cylinder 601 has a plug hole adapted to the second insertion end. In use, the appropriate pusher can be replaced according to the size of the cooling pipe 2. The second insertion end is inserted into the plug hole. When the hydraulic cylinder 601 outputs, the output end drives the first insertion end of the pusher to be inserted into the cooling pipe 2 to be pushed out. The pushing part moves forward and pushes the cooling pipe 2 out laterally.

[0023] This embodiment provides a traction mechanism, including a hand-cranked winch 11 mounted on a support frame 4. A transmission wheel 12 is also mounted on the support frame 4, with the transmission wheel 12 installed at a height higher than the hand-cranked winch 11. A steel wire rope 13 is wound around the shaft of the hand-cranked winch 11, and the end of the steel wire rope 13 passes around the transmission wheel 12 and connects to the bracket 5. The winch enables bidirectional self-locking. In use, rotating the hand-cranked winch 11 releases or rewinds the steel wire rope 13, which drives the bracket 5 to slide up and down along the support frame 4, thereby driving the jacking mechanism 6 to move to different heights.

[0024] This embodiment provides another traction mechanism, including a hand-cranked winch 11 mounted on a support frame 4. A drive sprocket is mounted on the shaft of the hand-cranked winch 11. A transmission sprocket is mounted at the upper and lower ends of the support frame 4. A chain meshes with the drive sprocket and the two transmission sprockets. The chain is fixedly connected to the bracket 5. In use, the hand-cranked winch 11 is rotated, causing the drive sprocket to rotate clockwise or counterclockwise, which in turn drives the chain to rotate. The chain drives the bracket 5 to slide up and down along the support frame 4, thereby moving the jacking mechanism 6 to different heights.
