[0006] This utility model provides a drug raw material pretreatment device with built-in pulverizing function, which solves the problems proposed in the prior art: the pulverizing device does not dry the raw material, causing the damp raw material to easily clump after pulverizing, resulting in clogging of the screen and low practicality; and it does not collect the debris generated during pulverization, causing the debris to float in the external environment and resulting in poor environmental performance.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A pharmaceutical raw material pretreatment device with built-in pulverizing function includes a feeding mechanism. The feeding mechanism comprises a support box, two arc-shaped guide plates welded to the upper inner wall of the support box, and four arc-shaped guide plates welded in pairs to the top outer walls of the two guide plates. A feeding mechanism is provided at the top of the support box. The feeding mechanism includes a heat-insulating cylinder penetrating and abutting against the top inner wall of the support box, two end caps bolted to the outer walls of the heat-insulating cylinder on both sides, an inner liner bolted to the outer walls of opposite sides of the two end caps, several ceramic heating rods bolted to the outer walls of flanges on both sides of the inner liner, a discharge frame penetrating and welded to the bottom inner wall of the inner liner, a ventilation pipe penetrating and screwed to the outer wall of the end caps, a pipe fan bolted to the outer wall of one end of the ventilation pipe, two connecting pipes fixed to the inner walls of the ventilation pipes, and an installation pipe penetrating and screwed to the outer wall of the end caps. A dust collection group is provided on one side of the support box. The dust collection assembly includes a conveying pipe screwed to the outer wall of one end of the mounting pipe, a connecting pipe that passes through and is welded to the lower inner wall of the conveying pipe, and a dust collection bag connected to the lower outer wall of the conveying pipe by a clamp. A mounting frame is bolted to one side of the outer wall of the support box. A stirring assembly is provided inside the inner liner. The stirring assembly includes a stirring motor bolted to one side of the outer wall of the mounting frame, a connecting shaft connected to one end of the output shaft of the stirring motor by a coupling, and a stirring frame connected to the outer wall of the connecting shaft by a pin. A discharge assembly is provided inside the support box. A crushing assembly is provided inside the support box. The crushing assembly includes a crushing motor bolted to one side of the outer wall of the mounting frame, a rotating shaft connected to one end of the output shaft of the crushing motor by a coupling, a transmission shaft with both ends passing through and connected to the outer walls of both sides of the support box by bearings, two gears that mesh with each other to form a transmission fit, and crushing rollers with several crushing teeth fixed on both outer walls.

[0009] Preferably, an inclined unloading plate is welded to the inner wall of the support box, and a discharge port is opened on the lower outer wall of one side of the support box, with the unloading plate abutting against the bottom inner wall of the discharge port.

[0010] Preferably, the two end caps are respectively bolted to the upper inner wall of the support box, a feed hopper is welded to the top inner wall of the inner liner, and the lower part of the feed hopper passes through and is fixed to the top outer wall of the insulation cylinder. A cover plate is hinged to the top outer wall of the feed hopper, and one end of the two connecting pipes passes through and is inserted into the outer wall of the flange on one side of the inner liner.

[0011] The above scheme generates heat through the operation of multiple ceramic heating rods to heat and dry the raw materials inside the inner liner. At the same time, the air between the insulation cylinder and the inner liner expands due to heat, and the hot air enters the ventilation pipe through two connecting pipes. The pipe fan mixes the outside air with the hot air and then delivers it into the inner liner.

[0012] Preferably, one end of the connecting pipe passes through and is inserted into the outer wall of the end cap located inside the inner liner, and an installation plate is welded to the upper outer wall of one side of the support box, and the lower part of the conveying pipe passes through and is inserted into the outer wall of the installation plate.

[0013] Through the above scheme, the duct fan transports the humid and hot air inside the inner liner to the conveying pipe. The debris and dust generated during drying enter the dust collector bag. At this time, the pressure inside the conveying pipe decreases. Under the action of pressure difference, the debris and dust generated during crushing in the support box mix with the air and enter the dust collector bag. The dust collector bag separates the air, debris and dust.

[0014] Preferably, one end of the connecting shaft passes through and is connected to the outer wall of one of the end caps via a bearing. Several rubber strips are fixed on the outer wall of the stirring rack, and the outer diameter of the rubber strips is slightly smaller than the inner diameter of the inner liner.

[0015] Preferably, the unloading assembly includes an unloading cylinder bolted to the top outer wall of the support box, a connecting column bolted to the bottom end of the piston rod of the unloading cylinder, an arc-shaped lifting plate welded to the bottom outer wall of the connecting column, several blocking blocks welded to the top outer wall of the lifting plate, and two limiting rods welded to the top outer wall of the lifting plate. The outer diameter of the blocking blocks is adapted to the inner diameter of the unloading hole on the unloading frame, and the two limiting rods pass through and slide on the top outer wall of the support box.

[0017] With the above scheme, the piston rod of the unloading cylinder drives the lifting plate and multiple block blocks to descend. The block blocks disengage from the unloading frame, and the dried raw material is transported between two crushing rollers by two guide plates and four guide plates. The crushing rollers crush the raw material under the drive of the crushing motor.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. Multiple ceramic heating rods generate heat to heat and dry the raw materials inside the inner liner. At the same time, the air between the insulation cylinder and the inner liner expands due to heat, and the hot air enters the ventilation pipe through two connecting pipes. The pipe fan mixes the outside air with the hot air and delivers it into the inner liner. The stirring motor drives the stirring frame to rotate and turn the raw materials, so that the raw materials can fully contact the heat. This can dry the raw materials before crushing, prevent the damp raw materials from clumping again after crushing, and improve practicality.

[0020] 2. The duct fan transports the humid, hot air from the inner liner to the conveying pipe. The debris and dust generated during drying enter the dust collector bag. At this time, the pressure inside the conveying pipe decreases. Under the action of the pressure difference, the debris and dust generated during crushing in the support box mix with the air and enter the dust collector bag. The dust collector bag separates the air, debris, and dust, and can collect the debris and dust in the raw materials, preventing the debris and dust from drifting into the external environment, thus improving environmental protection.

[0021] In summary, this utility model can dry the raw materials before crushing, preventing the damp raw materials from clumping again after crushing, thus improving its practicality. It can also collect the debris and dust in the raw materials, preventing the debris and dust from being scattered in the external environment, thus improving its environmental friendliness.
