Meanwhile, the standpipe 41 is provided with a control mechanism 12 for controlling the rotation of the baffle 9.

When the raw materials are transported by the airflow generated by the Roots blower 2, the baffle 9 is driven to rotate by the control mechanism 12. When the baffle 9 is rotated to the horizontal state, the baffle 9 can seal the lower port of the vertical pipe 41, so that the airflow in the air outlet of the roots blower 2 cannot enter the vertical pipe 41. At this time, the raw material located above the crushing roller 6 moves downward by its own weight, and the crushing roller 6 can secondarily crush the raw material as the raw material passes through the crushing roller 6, thereby enabling the raw material to be crushed as much as possible.

When the control mechanism 12 drives the baffle 9 to rotate reversely and the lower port of the vertical pipe 41 is opened, the air flow generated by the air outlet of the roots blower 2 enters the vertical pipe 41 again.

When the output shaft of the motor 8 rotates, the driving wheel 121 rotates synchronously with the output shaft of the motor 8, and then the synchronous belt 26 drives the driven wheel 122 and the input shaft of the speed reducer 17 to rotate under the driving of the driving wheel 121. Subsequently, the output shaft of the speed reducer 17 can drive the corresponding rotating shaft 10 to drive the baffle 9 to rotate, so as to realize the automatic opening and closing of the lower port of the vertical pipe 41.

Referring to fig. 4 and 5, a mounting hole 18 communicated with the inside of the feed hopper 32 is penetrated through the outer wall of the lower end of the feed hopper 32, and a flow distribution plate 19 for closing the lower port of the feed hopper 32 is penetrated horizontally in the mounting hole 18. Meanwhile, the feed hopper 32 is provided with an adjusting mechanism 20 for driving the movement of the diversion plate 19. The adjusting mechanism 20 drives the splitter plate 19 to move horizontally, and the splitter plate 19 is used for controlling the reciprocating opening and closing of the lower port of the feed hopper 32, so that the batch feeding operation of raw materials is realized.

Referring to fig. 3 and 5, a supporting frame 21 is fixedly connected to an outer wall of the feeding hopper 32, the adjusting mechanism 20 includes an adjusting pipe 201 horizontally and fixedly connected to the mounting frame 5, an adjusting rod 202 is horizontally and slidably connected to the adjusting pipe 201, and a sliding direction of the adjusting rod 202 is the same as a sliding direction of the flow distribution plate 19. Meanwhile, one end of the adjusting rod 202 is fixedly connected with the end of the flow distribution plate 19 located outside the feeding hopper 32, and the peripheral side wall of the adjusting rod 202 is engaged with the peripheral inner wall of the adjusting pipe 201. An exhaust pipe 22 communicated with the exhaust hole 13 is fixedly connected to the outer wall of the vertical pipe 41, and one end of the exhaust pipe 22 far away from the vertical pipe 41 is connected with one end of the adjusting pipe 201 far away from the feed hopper 32.

When the baffle 9 is in a horizontal state and the lower port of the vertical pipe 41 is closed, the air flow ejected from the air outlet of the roots blower 2 enters the exhaust pipe 22 through the exhaust hole 13. Subsequently, the air flow in the exhaust pipe 22 enters the adjusting pipe 201 and pushes the adjusting rod 202 to drive the flow dividing plate 19 to move, so that the flow dividing plate 19 blocks the lower port of the feed hopper 32.

Referring to fig. 5, a reset component for driving the splitter plate 19 to move towards the adjusting pipe 201 is arranged on the feeding hopper 32, a mounting block 23 is fixedly connected to one end of the splitter plate 19 located outside the feeding hopper 32, and the reset component is a plurality of reset springs 24 arranged between the mounting block 23 and the feeding hopper 32. One end of the return spring 24 is fixedly connected with the mounting block 23, and the other end is fixedly connected with the outer wall of the feeding hopper 32, so as to provide a stable driving force for the resetting of the mounting block 23 and the flow dividing plate 19. Meanwhile, the outer wall of the adjusting pipe 201 near one end of the exhaust pipe 22 is penetrated with a gas diffusion hole 25 communicated with the inside thereof, so that the gas in the adjusting pipe 201 can be slowly exhausted through the gas diffusion hole 25.

When the sealing disk 15 closes the exhaust hole 13, the air flow in the regulating tube 201 is slowly released through the air release hole 25. Meanwhile, the return springs 24 jointly drive the mounting block 23 to drive the splitter plate 19 to move towards the adjusting pipe 201 under the action of the elastic force of the return springs, so that the lower port of the feed hopper 32 is gradually opened.

When the material is required to be fed, the material is injected into the feed hopper 32. Then, the raw material in the feed hopper 32 is introduced into the roots blower 2 through the screw conveyor 31. Subsequently, a gas flow is generated inside the Roots blower 2 and the raw material is fed into the esterification tank through the vertical pipe 41 and the horizontal pipe 42. When the raw material in the vertical tube 41 passes through the crushing roller 6, the output shaft of the motor 8 drives the driving gear 71 to rotate, and then the driven gears 72 synchronously rotate and drive the corresponding crushing roller 6 to rotate. The crushing roller 6 then crushes the raw material.

Meanwhile, when the output shaft of the motor 8 rotates, the driving wheel 121 follows the output shaft of the motor 8 to rotate synchronously, and then the timing belt 26 drives the driven wheel 122 and the input shaft of the speed reducer 17 to rotate under the driving of the driving wheel 121. Subsequently, the output shaft of the reducer 17 drives the corresponding rotating shaft 10 to rotate the shutter 9. When the baffle 9 rotates the sealing disc 15 and the baffle 9 is horizontal, the baffle 9 closes the lower port of the standpipe 41 and one of the vent holes 16 is aligned with the vent hole 13.

At this time, the air flow in the air outlet of the roots blower 2 cannot enter the vertical tube 41, so that the raw material located above the crushing roller 6 moves downward under the action of its own gravity. The crushing roller 6 is capable of performing secondary crushing of the raw material as it passes through the crushing roller 6. Meanwhile, the air flow ejected from the air outlet of the roots blower 2 enters the exhaust pipe 22 through the exhaust hole 13. Subsequently, the air flow in the exhaust pipe 22 enters the adjusting pipe 201 and pushes the adjusting rod 202 to drive the flow dividing plate 19 to move, so that the flow dividing plate 19 blocks the lower port of the feed hopper 32. At this time, the plurality of return springs 24 are all in a compressed state.

As the baffle 9 continues to drive the sealing disc 15 to rotate, when the lower port of the vertical pipe 41 is opened, the air flow generated by the air outlet of the Roots blower 2 enters the vertical pipe 41 again. At this time, the material after the secondary crushing moves upward again under the pushing of the air current, and when the material passes through the crushing roller 6 again, the crushing roller 6 can crush the material again, thereby realizing the tertiary crushing of the material.

At the same time, the air discharge hole 13 is closed by the seal disk 15, and then the air flow in the regulator pipe 201 is slowly discharged through the air discharge hole 25. Subsequently, the mounting block 23 drives the diversion plate 19 towards the adjustment pipe 201 under the combined action of the return springs 24, so that the lower port of the feed hopper 32 is gradually opened. Then, the raw material in the feeding hopper 32 enters the screw conveyor 31 again, and the reciprocating operation is carried out, so that the quick feeding of the raw material can be realized.
