Problems solved by technology
[0005] Although it solves the above problems, it has shortcomings. When cooling the cooling box, the heat generated is directly removed and cannot be used. This consumes more heat energy, and at the same time, the effect of cooling the cooling box is not good. Therefore, we designed a A heating device for MPP cable protection pipe production to solve the above problems

The invention discloses a heating device for MPP cable protection pipe production. The heating device comprises a water tank and a heating cylinder, wherein an extruder cylinder is arranged in the heating cylinder, a sealing cavity is formed between the extruder cylinder and the heating cylinder, the water tank is fixedly connected to a cooling tank, a heating tank and a first water pump, and a cooling pipe is installed in the cooling tank. The heating device is reasonable in structure, the cooling pipe can be effectively cooled, the cooling uniformity is better so that the temperature of liquid in the cooling pipe can be reduced, materials are prevented from being decomposed due to too high plasticizing temperature, meanwhile, heat generated during cooling can be utilized, water in the water tank can be heated so as to be conveniently used in life or production machining, loss of other energy is reduced, energy can be saved, the water can be stirred when heated, the water can be heated more uniformly, and the heated water can be replaced conveniently.
Description
technical field [0001] The invention relates to the technical field of pipe material processing equipment, in particular to a heating device for the production of MPP cable protection pipes. Background technique [0002] Pipe is the material used to make pipe fittings. Different pipe fittings use different pipe materials, and the quality of the pipe directly determines the quality of the pipe fittings. MPP power pipes are divided into ordinary type and reinforced type, and reinforced type is divided into excavated pipe and non-excavated pipe. The so-called MPP non-excavated pipe is also called MPP jacking pipe, MPP pulling pipe, and MPP traction pipe. [0003] In the production process of MPP cable protection tube, a screw extruder is needed. During the extrusion process, it is necessary to keep the material in a hot-melt state, and at the same time prevent the material from decomposing due to high plasticizing temperature. Therefore, it is necessary to set the heating and ...
