[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figure 1 , Figure 2 and Figure 4 , a rapid mixing device for tire rubber powder and pyrolysis crude carbon black, including a mixing structure 1.

[0024] The re-mixing member 16 includes a mixing pipe 162 and support legs 161 installed at the lower end of the mixing pipe 162, and the support legs 161 are installed at the top end of the base 11. Rubber rings 163 are installed at both ends inside the mixing pipe 162, and a discharge plate 164 is installed in the middle of the bottom end of the mixing pipe 162.

[0025] The material pushing member 18 includes an external circular block 181 and a stacking pipe 182 installed on one side of the external circular block 181. An external ring 183 is installed on the outer side of the stacking pipe 182, and there are two sets of the external circular block 181, the stacking pipe 182 and the external ring 183. An anti-sticking layer 184 is provided inside the stacking pipe 182, and the external ring 183 moves inside the mixing pipe 162.

[0026] A through hole 185 is formed through the middle end of a group of the external circular blocks 181. A sealing ring 186 is installed inside the through hole 185. One end of the T-shaped pipe A192 is installed with a fixed pipe 191, and the fixed pipe 191 is installed inside the sealing ring 186. The position of the fixed pipe 191 is fixed, and the fixed pipe 191 is externally connected to a cold air pipe.

[0027] A moving groove 12 is formed at the top end of the base 11. A positive and negative thread screw 14 is movably installed inside the moving groove 12, and the positive and negative thread screw 14 is connected to the output end of the adjustment motor 13. A reverse T-shaped slider 15 is threadedly sleeved on the outer surface of the positive and negative thread screw 14. There are two sets of the reverse T-shaped sliders 15. The top ends of the two sets of the reverse T-shaped sliders 15 are respectively installed at the bottom ends of the two sets of the external circular blocks 181. When the two sets of the reverse T-shaped sliders 15 approach each other, it is convenient for the mixing pipe 162 to discharge materials. When the two sets of the reverse T-shaped sliders 15 move away from each other, the space used after the raw materials are mixed is enlarged.

[0028] The premixing member 17 includes a mixing pipe 171 and a mixing motor 172 installed at the top end of the mixing pipe 171. The output end of the mixing motor 172 is installed with a spiral rod 173, and the spiral rod 173 is arranged inside the mixing pipe 171. The rotating spiral rod 173 is used to preliminarily mix the tire rubber powder and the pyrolysis crude carbon black.

[0029] An inclined material frame A174 and an inclined material frame B175 are respectively installed on both sides of the upper end of the mixing pipe 171. The inclined material frame A174 and the inclined material frame B175 are inclined. One ends of the arranged inclined material frame A174 and the inclined material frame B175 penetrate through the outer surface of the mixing pipe 171.

[0030] In this embodiment: The tire rubber powder and the pyrolysis crude carbon black are respectively poured into the interiors of the inclined material frame A174 and the inclined material frame B175. The tire rubber powder and the pyrolysis crude carbon black flow into the interior of the mixing pipe 171 along the inclined inclined material frame A174 and the inclined material frame B175. The mixing motor 172 operates to drive the screw rod 173 to rotate. When the raw materials enter the interior of the mixing pipe 171, the tire rubber powder and the pyrolysis crude carbon black are preliminarily mixed. The mixed raw materials are discharged into the interior of the mixing pipe 162 along with the rotating screw rod 173. The fixed pipe 191 is externally connected to a cold air pipe, and the cold air is discharged into the interiors of the T-shaped pipe A192 and the middle pipe 193 through the fixed pipe 191. The cold air is discharged by the one-way valve 195 to cool and disperse the raw materials falling into the interior of the mixing pipe 162, preventing the raw materials from agglomerating due to frictional heat inside the premixing member 17. The dispersed raw materials fall onto the inner bottom end of the mixing pipe 162 for mixing.

[0031] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figure 1 , Figure 3 and Figure 4 . The gas mixing member 19 includes a middle pipe 193 and an inner bottom groove 197 opened at the inner bottom end of the T-shaped pipe A192. The top end of the middle pipe 193 is installed with a one-way valve 195 through it. On both sides inside the middle pipe 193, a T-shaped pipe A192 and a T-shaped pipe B194 are respectively movably installed. The bottom ends of the T-shaped pipe A192 and the T-shaped pipe B194 are both installed with limit blocks 196, and the limit blocks 196 are slidably installed inside the inner bottom groove 197. The cold air is discharged into the interior of the middle pipe 193 through the T-shaped pipe A192, and the one-way valve 195 discharges the cold air, cooling the raw materials while mixing them.

[0032] In this embodiment: The operation of the motor 13 is adjusted, and two inverted T-shaped sliders 15 threadedly sleeved on the outer surface of the forward and reverse threaded screw 14 move in opposite directions. The external ring 183 moves inside the mixing tube 162 towards one side of the rubber ring 163, expanding the space for placing the mixed raw materials. After mixing, the operation of the motor 13 is adjusted to drive the forward and reverse threaded screw 14 to rotate in the reverse direction, and the two inverted T-shaped sliders 15 move towards each other. The external ring 183 moves towards the middle end of the mixing tube 162, and the discharge plate 164 is removed from the bottom end of the mixing tube 162. The two moving external rings 183 push the raw materials towards the middle bottom end of the mixing tube 162, facilitating the discharging of the mixing structure 1. Since the inside of the stacking tube 182 is in a table shape and the bottom end inside the stacking tube 182 faces the middle end of the mixing tube 162, the raw materials inside the stacking tube 182 can be discharged into the inside of the mixing tube 162 during the moving process. The provided anti-adhesion layer 184 is processed to prevent the raw materials from adhering to the inner wall of the stacking tube 182. As the two external round blocks 181 approach each other, both the T-shaped tube A192 and the T-shaped tube B194 drive the limit block 196 to move in the inner bottom groove 197, and the length of the gas mixing member 19 is shortened. Since the limit block 196 and the inner bottom groove 197 are used in cooperation with each other, the angle of the middle tube 193 can be maintained when mixing the raw materials, that is, the gas outlet end of the one-way valve 195 can be kept facing the bottom end of the mixing tube 171.

[0033] Working principle: The tire rubber powder and the pyrolysis carbon black flow into the inside of the mixing tube 171 along the inclined inclined material frame A174 and the inclined material frame B175. The mixing motor 172 operates to drive the screw rod 173 to rotate, and the tire rubber powder and the pyrolysis carbon black are preliminarily mixed. The cold air is discharged from the one-way valve 195 to cool and disperse the raw materials falling into the inside of the mixing tube 162, preventing the raw materials from agglomerating due to frictional heat inside the premixing member 17. The dispersed raw materials fall on the inner bottom end of the mixing tube 162 for mixing.

[0034] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
