Description

Technical Field

[0001] This utility model relates to the field of concrete pipe technology, specifically to an energy-saving device for recycling residual grout from PCCP pipes. Background Technology

[0002] Currently, prestressed concrete cylinder pipe (PCCP) is a new type of rigid pressure pipe. It consists of a high-strength concrete core with a steel cylinder, wound with prestressed steel wire, sprayed with a cement mortar protective layer, and welded to the steel cylinder using a steel socket. The socket has a grooved sealing ring, forming a flexible joint with a sliding rubber ring. It is a composite structure composed of steel plate, concrete, high-strength steel wire, and cement mortar. However, during the cement mortar spraying process, excess spraying material is generated and needs to be recycled. Existing methods for recycling spraying material are labor-intensive, and the double-layer winding process generates even more excess material, requiring more personnel to complete this task, significantly increasing labor costs. Furthermore, the material scattered on the ground around the spraying machine during manual collection can introduce large particles or concrete waste, requiring screening before reuse, which also increases the labor intensity. Therefore, we propose an energy-saving device for recycling PCCP spraying material to solve the above problems. Utility Model Content

[0009] Preferably, a support block is fixedly provided on the upper end of the base, located below the rotating platform and the second outlet pipe. Both ends of the support block are rotatably connected to a transmission shaft. A transmission pulley is fixedly provided on the transmission shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During the spraying of cement mortar, the mortar with high impact force is collected by the collection shell to ensure that the mortar does not fall outside the working platform. The mortar collected in the collection shell is then transported to the conveyor belt through the first outlet pipe and the second outlet pipe. The mortar that falls onto the rotating platform along the outer surface of the concrete pipe is then transferred to the conveyor belt through the first and second telescopic scrapers. The conveyor belt transports the collected mortar to the screening plate, which screens the mortar. The mortar that can be reused falls into the first storage chamber. The vibrator shakes the screening plate to put large particles of waste into the second storage chamber, thus realizing the collection and screening of the spraying residue.

[0026] Example 2:

[0027] Reference Figure 1-6 This is the second embodiment of the present invention, based on the previous embodiment.
