Description

Technical Field

[0001] The utility model relates to the technical field of granulation equipment, in particular to a banburying granulation equipment for producing anti-sag pipes. Background Art

[0002] Anti-sag pipe is a specially designed pipe that improves the melt strength of the pipe by adding specific materials or adopting special processes, thereby reducing the problem of uneven pipe wall thickness caused by melt sag (sag) during the production process. During its production process, the raw materials need to be mixed at high temperature in an internal mixer until the material has a uniform rheological shape, and then granulated by a granulator to facilitate subsequent feeding to the injection machine.

[0003] In most existing internal mixing and granulation equipment used for the production of anti-sag pipes, the material output pipe is often exposed during use. When the working environment temperature is low, the material in the output pipe tends to lose a lot of heat, causing the semi-fluid material to cool down and condense to a certain extent, affecting the normal progress of the granulation work, reducing production efficiency, and causing great inconvenience to the staff.

DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-3 As shown, a mixing and granulating device for producing anti-sag pipes includes a granulator body 1;

[0023] The output end of the granulator body 1 is provided with a discharge pipe 2, the outer side of the discharge pipe 2 is covered with a heat-insulating cover 8, and several groups of spaced-apart heat-conducting fins 9 are provided between the discharge pipe 2 and the heat-insulating cover 8. A liquid inlet pipe 10 is provided at the bottom of the heat-insulating cover 8, and a liquid outlet pipe 11 is provided on the top of the heat-insulating cover 8. A water tank 12 is provided below the output end of the discharge pipe 2, and a water pipe 15 and a return pipe 16 are provided on one side of the water tank 12. A filter screen 17 matching the water pipe 15 is provided at the bottom of the water tank 12, and the output end of the return pipe 16 is inclined toward the filter screen 17. A pressure pump 18 is provided at the output end of the water pipe 15, and the output ends of the pressure pump 18 and the return pipe 16 are respectively connected to the liquid inlet pipe 10 and the liquid outlet pipe 11 through two groups of rubber hoses 19. The device is connected to the liquid outlet pipe 11 through the outlet. When the material is output from the material pipe 2 for granulation, the granular material falls into the water tank 12. The water tank 12 can store cooling water to cool and shape the prepared granular material. The heated cooling water enters the pressure pump 18 through the water pipe 15. The pressure pump 18 pressurizes the water body and then transports it to the insulation cover 8 through the rubber hose 19. Several groups of spaced-apart heat-conducting fins 9 arranged in the insulation cover 8 can transfer the heat of the cooling water to the discharge pipe 2, thereby achieving the effect of insulation. After the circulating water returns to the water tank 12 through the return pipe 16, since the return pipe 16 is inclined toward the filter screen cover 17, the water flow can flush the filter screen cover 17, thereby preventing smaller granular raw materials in the water from clogging the filter screen cover 17 and affecting the normal water output of the pressure pump 18.

[0024] In this embodiment, specifically, a feed hopper 3 is provided on the top of the discharge pipe 2, and an extrusion end head 4 is provided at the output end of the discharge pipe 2. Several groups of holes are opened on the extrusion end head 4. A servo motor 5 is mounted on one end face of the extrusion end head 4. The output end of the servo motor 5 is provided with a cutting blade 6 matching the extrusion end head 4. The feed hopper 3 is used to put in the material. When the material is transported to the extrusion end head 4 through the discharge pipe 2, the several groups of holes opened on the extrusion end head 4 separate the material so that it is output as strip material of a certain diameter. The cutting blade 6 is then driven by the servo motor 5 to cut the strip material to obtain granular material.

[0025] In this embodiment, specifically, a spiral feeding rod 7 for feeding materials is rotatably provided inside the discharge pipe 2, and a receiving mesh box 13 for receiving materials is provided inside the water tank 12. The mesh structure of the receiving mesh box 13 allows the cooling water to pass through normally, and can receive and enclose the granular materials to prevent the granular materials from being scattered everywhere, and slots are provided on both sides of the receiving mesh box 13 to facilitate the staff to take it out of the water tank 12 for transportation.

[0026] In this embodiment, specifically, a drain pipe 14 is provided on the other side of the water tank 12 , and a valve is provided on the drain pipe 14 . When the device is not in use, the cooling water in the water tank 12 can be discharged through the provided drain pipe 14 .

[0027] In this embodiment, specifically, the material of the rubber hose 19 is heat-resistant rubber.

[0028] The above describes an embodiment of the present invention in detail.
