Description

Technical Field

[0001] The utility model relates to the field of mixing for polymer material production, in particular to a polymer material processing device for reinforcement and plugging. Background Art

[0002] Polymer filling and curing agents are generally used in cracks in coal rock strata or concrete (closed cracks in coal rock strata can be opened under high pressure). They can extend along the cracks in coal rock strata or concrete until all cracks (including cracks that are difficult to detect with the naked eye and cracks that are reopened under high pressure) are filled.

[0003] During the production process of polymer filler curing agent (such as Marisan), it is necessary to add each raw material in proportion and stir it thoroughly. The stirred material has a certain viscosity and will adhere to the inner wall of the mixing tank. In the prior art, a scraper rod is installed on the agitator. When the scraper rod rotates with the agitator, the material attached to the inner wall of the mixing tank will be scraped off. However, this method will continue to contact with the inner wall of the mixing tank during the stirring process, causing excessive wear of the inner wall of the mixing tank or the scraper rod, which is not practical.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0019] In this embodiment: when producing the polymer plugging and reinforcing agent, each raw material is added to the stirring tank 1 in proportion, and then fully stirred. After the stirring is completed, the material in the stirring tank 1 can be discharged by opening the valve on the discharge pipe 2. When discharging, the pressure mechanism is started, and the pressure mechanism applies pressure to the inner cavity of the connecting plate 6. At this time, the sliding plate 16 slides out of the connecting plate 6 and contacts the inner periphery of the stirring tank 1. The sliding plate 16 that moves out and rotates scrapes off the material attached to the inner wall of the stirring tank 1 to avoid material residue. During the stirring process, the sliding plate 16 is in the inner cavity of the connecting plate 6 and does not contact the inner periphery of the stirring tank 1, which can avoid the loss caused by long-term contact during the stirring process, thereby improving the service life of the sliding plate 16.

[0020] It should be noted that a seal is provided at the connection position between the connecting plate 6 and the sliding plate 16 to prevent materials from flowing into the inner cavity of the connecting plate 6, and when the sliding plate 16 is in the reset state, one end of the sliding plate 16 is flush with the outer end of the connecting plate 6.

[0023] Please refer to Figure 1 , Figure 2 and Figure 4 The pressure mechanism includes a connecting pipe 11 fixedly connected to the top of the stirring tank 1 through a bracket, one port of the connecting pipe 11 is connected to a buffer tank 12, an electric push cylinder 15 is fixedly installed on the outer periphery of the buffer tank 12, the output end of the electric push cylinder 15 is connected to a fixed plate 13, a piston rod 14 penetrating into the inner cavity of the buffer tank 12 is installed at the lower side of the fixed plate 13, and one end of the buffer tank 12 located in the inner cavity of the piston rod 14 is fixedly connected to a piston plate 18.

[0024] In this embodiment: when discharging, the electric push cylinder 15 is started, and the telescopic part of the electric push cylinder 15 is retracted into the cylinder sleeve. The output end of the electric push cylinder 15 drives the piston rod 14 to move toward the inner cavity of the buffer tank 12 through the fixed plate 13. The piston rod 14 simultaneously drives the piston plate 18 to move in the buffer tank 12. At this time, the piston plate 18 applies an extrusion force to the liquid medium. The economic pressure acts on one end of the sliding plate 16, and the sliding plate 16 is forced to slide out of the inner cavity of the connecting plate 6. At this time, the spring 17 is stretched, and the sliding plate 16 can slide out.

[0025] During stirring, the electric push cylinder 15 is started, and the electric push cylinder 15 drives the piston plate 18 to move in the opposite direction through the piston rod 14, the hydraulic pressure is reduced, the spring 17 is reset, and the sliding plate 16 is pulled back to the initial position.

[0026] Please refer to Figure 2 and Figure 4One end of the connecting pipe 11 away from the buffer tank 12 is butt-jointed with the top of the rotating shaft 4, and the outer wall of the vertical rod portion of the connecting pipe 11 is fixedly connected with a rotating head 10, the inner periphery of the rotating head 10 is rotatably connected to the rotating shaft 4, and a seal is provided at the rotatable connection between the rotating head 10 and the rotating shaft 4, the interiors of the rotating shaft 4 and the agitator 5 are both hollow structures, the inner cavity of the rotating shaft 4 is connected to the inner cavity of the agitator 5, and the inner cavity of the agitator 5 is connected to the inner cavity of the connecting plate 6.

[0027] In this embodiment: the liquid medium is filled in the inner cavity of the agitator 5, the connecting plate 6, and the rotating shaft 4, so the movement of the sliding plate 16 can be achieved through the hydraulic mechanism, and when the rotating shaft 4 rotates, the rotating shaft 4 and the rotating head 10 produce relative rotation, and the connecting pipe 11 will not be driven to rotate by the rotating head 10, and the setting of the seal can prevent the liquid medium from leaking from the docking position between the rotating head 10 and the rotating shaft 4.
