Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline heat preservation, and specifically refers to an injection device for heat preservation materials of a heat preservation pipeline. Background Art

[0002] The injection of heat preservation materials for heat preservation pipelines is an important link in pipeline heat preservation construction. Commonly used heat preservation materials include polyurethane, rock wool, glass wool, etc. For foaming heat preservation materials such as polyurethane, the on-site foaming method or direct pouring method is usually used for injection. The direct pouring method refers to directly pouring the mixed foaming slurry into the gap between the inner pipe and the outer sleeve, and filling the entire space through foaming expansion to form a heat preservation layer.

[0003] Currently, the existing injection devices for heat preservation materials of heat preservation pipelines have the following problems: When the existing injection device for heat preservation materials of heat preservation pipelines adopts the vertical pouring method, due to the influence of gravity and the fluidity of the slurry, voids or uneven density will exist inside the poured heat preservation materials, thus affecting the overall heat preservation effect and reducing the vertical pouring quality of the heat preservation materials. Therefore, it cannot meet the current usage requirements for the injection device of heat preservation materials of heat preservation pipelines. Summary of the Invention

[0007] Still further, the outer cylinder positioning mechanism further includes a compression spring, an arc-shaped block and an annular plate. The compression spring is arranged between the top pressing plate and the U-shaped carrier plate outside the guiding rod. The arc-shaped blocks are respectively arranged on the upper wall of the U-shaped carrier plate and the bottom wall of the top pressing plate. The annular plate is arranged on the upper wall of the arc-shaped block on the upper wall of the U-shaped carrier plate.

[0008] Even further, the liquid storage mechanism includes a liquid storage port, an elastic sheet, a magnetic holder, a pulling rod, a driving electromagnet and a return spring.

The stirring mechanism 27 includes a stirring frame 28, a stirring nut 29, a rotating ring plate 30, a hand rocker 31, a stirring sleeve 32, and a spiral blade 33. The stirring frame 28 is slidably arranged on the outer side of the lifting slide column 11 below the sliding frame 12. The stirring nut 29 is arranged on the outer side of the lifting slide column 11 below the stirring frame 28. The stirring nut 29 is threadedly connected to the lifting slide column 11. The rotating ring plate 30 is rotatably arranged on the side of the stirring frame 28 away from the lifting slide column 11. The rotating ring plate 30 is rotatably arranged between the top pressing plate 6 and the fixed ring frame 15. The hand rockers 31 are symmetrically arranged on the upper wall of the rotating ring plate 30. The stirring sleeve 32 is arranged on the bottom wall of the rotating ring plate 30. The stirring sleeve 32 is provided with a through hole. The spiral blades 33 are respectively arranged on the side wall and the inner wall of the stirring sleeve 32.

[0022] During specific use, in the initial state, the stirring frame 28 is placed at one end of the lifting slide column 11 close to the sliding frame 12. The stirring frame 28 drives the stirring sleeve 32 to be located above the top pressing plate 6 and the fixed ring frame 15. Manually pull the top pressing plate 6. The top pressing plate 6 slides upward along the guide rod 4 by deforming the pressing spring 5. The top pressing plate 6 drives the arc-shaped block 7 away from the annular plate 8. The distance between the arc-shaped block 7 and the annular plate 8 increases. Place the outer thermal insulation pipe between the arc-shaped block 7 and the annular plate 8. Then release the top pressing plate 6. The top pressing plate 6 slides along the guide rod 4 and drives the arc-shaped block 7 to move toward the side close to the annular plate 8 by the deformation reset of the pressing spring 5. The outer thermal insulation pipe is fixed between the arc-shaped block 7 and the annular plate 8. The pipe to be insulated is placed on the upper wall of the annular convex plate 18 through the fixing port 16. The outer diameter of the pipe is the same as the inner diameter of the fixing port 16. Rotate the limit nut 13, and the limit nut 13 at the bottom of the sliding frame 12 rotates and descends along the lifting sliding column 11. The sliding frame 12 slides along the lifting sliding column 11 to drive the fixing ring frame 15 to be sleeved on the outside of the pipe. The fixing ring frame 15 and the top pressing plate 6 are horizontally arranged. Rotate the limit nut 13 above the sliding frame 12, and the limit nut 13 rotates and descends along the lifting sliding column 11 to fit with the upper wall of the sliding frame 12. The sliding frame 12 is fixed on the outside of the lifting sliding column 11. Rotate the fixing bolt 17, and the fixing bolt 17 rotates along the inner wall of the fixing ring frame 15 to fit with the side wall of the pipe. The pipe is fixed on the upper wall of the annular convex plate 18. At this time, the outer insulating pipe is sleeved on the outside of the pipe, and the outer insulating pipe is concentric with the pipe. There is a gap between the outer insulating pipe and the pipe for pouring the insulating material. Pour the insulating material into the gap between the outer insulating pipe and the pipe. The poured insulating material is horizontal with the end face of the outer insulating pipe, and the direct pouring operation of the insulated pipe is completed; During the pouring process, due to the action of gravity, the heavier particles or components will gradually settle downward, while the lighter particles or components will float on the upper part, resulting in a density difference between the upper and lower parts, affecting the overall heat preservation effect of the insulated pipe. When the insulating material after pouring needs to be evenly stirred, the elastic sheet 22 is flush with the upper wall of the annular plate 8, and the distance between the driving electromagnet 25 and the magnetic frame 23 is the minimum value. The driving electromagnet 25 is energized to generate magnetism, and the driving electromagnet 25 and the magnetic frame 23 are arranged with the same poles. The distance between the driving electromagnet 25 and the magnetic frame 23 increases. Under the action of the repulsive force, the driving electromagnet 25 drives the pull rod 24 to pull the elastic sheet 22 to deform. After the elastic sheet 22 deforms, the return spring 26 is compressed. After the elastic sheet 22 deforms, it bulges outward to expand the space between the outer insulating pipe and the pipe. The insulating material between the outer insulating pipe and the pipe enters the elastically bulging elastic sheet 22, and the liquid level height of the insulating material between the outer insulating pipe and the pipe decreases, facilitating the stirring sleeve 32 to drive the spiral blade 33 to enter the insulating material without overflowing; Manually rotate the stirring nut 29. The stirring nut 29 rotates and descends along the lifting slide column 11. The stirring frame 28 slides and descends along the lifting slide column 11 and fits with the stirring nut 29. The stirring frame 28 drives the stirring sleeve 32 to insert into the gap between the top pressing plate 6 and the fixed ring frame 15 through the rotating ring plate 30. The stirring sleeve 32 drives the spiral blade 33 into the heat-insulating material between the outer heat-insulating pipe and the pipeline. The liquid level of the heat-insulating material between the outer heat-insulating pipe and the pipeline rises. Rotate the rotating ring plate 30 through the hand rocker 31. The rotating ring plate 30 drives the spiral blade 33 to rotate in the heat-insulating material through the stirring sleeve 32. The spiral blade 33 stirs out a channel for the liquid to move upward in the heat-insulating material, so as to facilitate swirling the heavier particles or components deposited in the bottom space between the outer heat-insulating pipe and the pipeline to the middle or top of the outer heat-insulating pipe and the pipeline, reducing the probability of non-uniformity in the heat-insulating material after pouring, and ensuring the heat-insulating performance of the pipeline after pouring; After stirring the heat-insulating material, pull the stirring frame 28. The stirring frame 28 drives the stirring sleeve 32 to move away from between the top pressing plate 6 and the fixed ring frame 15 through the rotating ring plate 30. The stirring sleeve 32 drives the spiral blade 33 to be withdrawn from the heat-insulating material between the outer heat-insulating pipe and the pipeline. Rotate the stirring nut 29. The stirring nut 29 rotates and rises along the lifting slide column 11 and fits with the bottom wall of the stirring frame 28. At this time, the liquid level of the heat-insulating material between the outer heat-insulating pipe and the pipeline drops. The driving electromagnet 25 is powered off and demagnetized. After the return spring 26 resumes elongation, it drives the elastic piece 22 to resume to a position flush with the upper wall of the annular plate 8. The heat-insulating material inside the outwardly protruding elastic piece 22 flows back into the space between the outer heat-insulating pipe and the pipeline. The liquid level of the heat-insulating material between the outer heat-insulating pipe and the pipeline rises again, thus completing the pouring operation of the pipeline heat-insulating material; After the heat-insulating material cools down, rotate the limit nut 13 above the sliding frame 12. The limit nut 13 rotates and moves away from the sliding frame 12 along the lifting slide column 11. Rotate the fixing bolt 17. The fixing bolt 17 rotates along the inner wall of the fixed ring frame 15 and moves away from the side wall of the pipeline. Lift the sliding frame 12. The sliding frame 12 slides along the lifting slide column 11 and drives the fixed ring frame 15 to rise. The fixed ring frame 15 moves away from the outside of the pipeline. Pull the top pressing plate 6. The top pressing plate 6 slides and rises along the guide rod 4 through the deformation of the pressing spring 5, and takes out the outer heat-insulating cylinder and the pipeline connected together by the heat-insulating material from the upper wall of the U-shaped carrier plate 2, completing the injection operation of the heat-insulating material for the heat-insulating pipeline; Just repeat the above operations when using next time.
