[0019] The first embodiment of the present application is as follows:

[0020] Please refer to Figures 1 to 4 , wherein Figure 1 is a schematic diagram of the overall structure of the expander processing and drying equipment according to the first embodiment of the present invention Figure 2 is a schematic diagram of the structure of the averaging component according to the first embodiment of the present invention Figure 3 is a schematic diagram of the structure of the heating component according to the first embodiment of the present invention Figure 4 is a schematic diagram of the internal structure of the drying oven according to the first embodiment of the present invention.

The feeding and discharging component includes a feeding pipe 113, a feeding hopper 114, a discharging pipe 115, and a discharging valve 116. By the foregoing solution, the problem that the heat flow inlet of the expander processing and drying equipment is set above, the heat flow outlet is set below, and two heat flow inlets and two heat flow outlets are respectively set, and the heat flow cannot be evenly dispersed on the outer surface of the device, which is likely to cause low drying efficiency of the expander during use, is solved. It can be understood that the foregoing solution can be used in the scenario of drying the expander during expander processing, and can also be used to solve the problem of raw material feeding and discharging during expander processing.

[0021] For this specific embodiment, the number of the connecting frames 102 is multiple. The multiple connecting frames 102 are respectively fixedly connected to the drying box 101 and are respectively located at the bottom of the drying box 101. The fixing ring 103 is fixedly connected to the connecting frames 102 and is located between the connecting frames 102. The rotating shaft 104 is rotatably connected to the fixing ring 103 and passes through the drying box 101. The motor 105 is fixedly connected to the rotating shaft 104 and is located at the top of the rotating shaft 104. The screw conveyor shaft 106 is fixedly connected to the rotating shaft 104 and is located between the fixing ring 103 and the motor 105. The heating assembly and the feeding and discharging assembly are respectively connected to the drying box 101. The connecting frames 102 provide a supporting function for the fixing ring 103 and the rotating shaft 104. The fixing ring 103 provides a limiting function for the rotating shaft 104. The rotating shaft 104 provides a driving function for the screw conveyor shaft 106. The motor 105 provides power for the rotating shaft 104. When the equipment is in use, the rotation of the motor 105 drives the rotating shaft 104 to rotate along the fixing ring 103, and at the same time drives the screw conveyor shaft 106 to rotate. The expansion agent raw material is pumped from the bottom of the drying box 101 to above the heat conduction cylinder 108 along the heat conduction cylinder 108 through the screw conveyor shaft 106, and then is discharged from the heat conduction cylinder 108 to between the drying box 101 and the heat conduction cylinder 108 through the gaps provided in the heat conduction cylinder 108, which is convenient for uniformly drying and conducting heat on the expansion agent raw material in the drying box 101.

[0022] Wherein, the top plate 107 is fixedly connected to the drying box 101 and is located between the motor 105 and the drying box 101. The heat conduction cylinder 108 is fixedly connected to the top plate 107 and is located outside the screw conveyor shaft 106. The top plate 107 provides a supporting function for the motor 105. The heat conduction cylinder 108 provides a protecting function for the screw conveyor shaft 106 and conducts the heat of the heat conduction pipe 111 to the inside of the heat conduction cylinder 108 at the same time, so as to facilitate uniformly heating the expansion agent raw material.

[0023] Secondly, the heat flow pump 109 is fixedly connected to the drying box 101 and is located outside the drying box 101. The inflow pipe 110 is fixedly connected to the heat flow pump 109 and passes through the drying box 101. The heat conduction pipe 111 is fixedly connected to the inflow pipe 110 and is located between the drying box 101 and the heat conduction cylinder 108. The outflow pipe 112 is fixedly connected to the heat conduction pipe 111 and passes through the drying box 101. The heat flow pump 109 pumps the external heat flow into the heat conduction pipe 111 through the inflow pipe 110, and after the heat conduction is completed through the heat conduction pipe 111, it is then led out through the outflow pipe 112, which is convenient for recycling the heat flow.

[0024] Again, the feed pipe 113 is fixedly connected to the top plate 107 and is located at the top of the top plate 107. The feed hopper 114 is fixedly connected to the feed pipe 113 and is located at the top of the feed pipe 113. Raw materials are pumped into the space between the drying box 101 and the heat conduction cylinder 108 through the feed hopper 114 and the feed pipe 113. At this time, the first heating is carried out, and then the raw materials are lifted by the screw conveyor shaft 106. During this process, cyclic heating is performed, increasing the drying efficiency of the blowing agent raw materials.

[0025] Finally, the discharge pipe 115 is fixedly connected to the drying box 101 and is located at the bottom of the drying box 101. The discharge valve 116 is fixedly connected to the discharge pipe 115 and is located outside the discharge pipe 115. After drying is completed, the discharge valve 116 is opened, and the dried blowing agent raw materials flow out of the drying box 101 through the discharge pipe 115, facilitating the discharging of the blowing agent raw materials.

[0026] When using the blowing agent processing and drying equipment of this embodiment, the connecting frame 102 provides a supporting effect for the fixed ring 103 and the rotating shaft 104. The fixed ring 103 provides a limiting effect for the rotating shaft 104. The rotating shaft 104 provides a driving effect for the screw conveyor shaft 106. The motor 105 provides power for the rotating shaft 104. When the equipment is in use, through the rotation of the motor 105, the rotating shaft 104 is driven to rotate along the fixed ring 103, and at the same time, the screw conveyor shaft 106 is driven to rotate. The blowing agent raw materials are pumped from the bottom of the drying box 101 to the upper part of the heat conduction cylinder 108 along the heat conduction cylinder 108 through the screw conveyor shaft 106, and then discharged from the heat conduction cylinder 108 to the space between the drying box 101 and the heat conduction cylinder 108 through the gaps provided in the heat conduction cylinder 108, facilitating the uniform drying and heat conduction of the blowing agent raw materials in the drying box 101, and solving the problem that the heat flow inlet of the blowing agent processing and drying equipment is set at the upper part, the heat flow outlet is set at the lower part, and two heat flow inlets and two heat flow outlets are respectively set, and the heat flow cannot be evenly dispersed on the outer surface of the device, which easily leads to low drying efficiency of the blowing agent during use.
