Description

Technical Field

[0001] The utility model belongs to the technical field of mixing equipment, and particularly relates to a high-pressure mixing equipment for raw materials of PIR pipes. Background Art

[0002] In the process of manufacturing PIR pipes, materials need to be fed into the tank under high pressure for mixing. In traditional high-pressure mixing equipment, a valve is arranged at the inlet for receiving raw materials. The valve needs to bear high-pressure impact for a long time, resulting in a shortened service life. At the same time, large-particle raw materials will be carried in the raw materials, which has an adverse effect on the valve.

[0003] In addition, when the valve is closed, the raw materials will accumulate at the valve. If the raw materials solidify, it will affect the opening of the valve, and the entry of large-particle raw materials or hard impurities into the tank will lead to poor mixing effect.

[0004] Therefore, it is urgent to develop a new high-pressure mixing equipment for raw materials of PIR pipes to solve the technical problems of how to overcome the influence of high pressure and large-particle raw materials on the service life of the valve in traditional high-pressure mixing equipment and the easy blockage of materials during startup and shutdown.

[0039] In at least one embodiment, by arranging the feeding filtering mechanism 3 to connect the high-pressure feeding mechanism 2 and the mixing tank 1, the feeding port is opened by the high-pressure impact on the feeding filtering mechanism 3, and after the high pressure disappears, the feeding filtering mechanism 3 resets under its own elastic force to close the feeding port, which can enable the feeding filtering mechanism 3 to withstand high-pressure impact for a long time without affecting its service life. At the same time, the feeding filtering mechanism 3 can filter large-particle raw materials, and the feeding filtering mechanism 3 can realize self-cleaning function during the reciprocating movement process, and can crush large-particle raw materials to avoid material blockage.

[0040] In at least one embodiment, the high-pressure feeding mechanism 2 includes: a high-pressure conveying pipeline 21; one end of the high-pressure conveying pipeline 21 is connected to a high-pressure feeding device, and the other end of the high-pressure conveying pipeline 21 is connected to the corresponding feeding filtering mechanism 3.

[0041] Specifically, the high-pressure feeding device high-pressures the raw materials for PIR pipes and conveys them towards the feeding filtering mechanism 3 through the high-pressure conveying pipeline 21 to realize the feeding function.

[0042] In at least one embodiment, please refer to Figure 2 , the feeding filtering mechanism 3 includes: a fixed pipe 31, a filtering pipe 32, and an elastic sealing component 33; the fixed pipe 31 is installed in the feeding port, one side of the fixed pipe 31 is connected to the high-pressure feeding mechanism 2, the other side of the fixed pipe 31 is connected to the filtering pipe 32, the filtering pipe 32 is located in the mixing tank 1, and the elastic sealing component 33 is movably installed in the filtering pipe 32.

[0045] Specifically, the elastic sealing component 33 enters the filtering pipe 32 in the force state and can open the feeding port.

[0046] Specifically, the elastic plugging component 33 and the filter tube 32 cooperate to adjust the opening degree of the feed inlet, and the pressing distance of the elastic plugging component 33 is determined by the magnitude of the pressure.

[0047] Specifically, the elastic plugging component 33 reciprocates between the fixed tube 31 and the filter tube 32. On the one hand, it can crush large-particle raw materials to avoid waste of resources. On the other hand, it can also scrape the raw materials remaining on the fixed tube 31 and the filter tube 32, playing a role of self-cleaning.

[0055] In at least one embodiment, the diameters of the fixed tube 31, the filter tube 32, and the plugging plate 331 are the same, which can ensure the function of opening and closing the feed inlet.

[0056] In at least one embodiment, please refer to Figure 4 , a plurality of ball plungers 334 are arranged on the outer edge of the plugging plate 331.

[0057] Specifically, the ball plungers 334 can be pressed against the filter holes 321, which can prevent the raw materials from blocking the filter holes 321.
