DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a crushing and drying integrated machine, comprising a crushing box 1 and a filter screen 2 located at the bottom of the crushing box 1. The crushing box 1 can adopt the existing technology in the patent document mentioned in the background technology. The function of the filter screen 2 is to screen qualified particles, and unqualified particles continue to be crushed by the crushing knife in the crushing box 1 at high speed. A discharge pipe 3 is arranged at the bottom of the crushing box 1 below the filter screen 2. The discharge pipe 3 is a channel for discharging qualified particles after the raw materials of the medicine are crushed downward.

[0024] The technical solution also includes an air lock 4, a screw conveyor 5, a heating sleeve 6 and an exhaust pipe 7. The top inlet of the air lock 4 is connected to the discharge pipe 3. The air lock 4 serves to avoid the problem of dust when the discharge pipe 3 discharges materials. Its function is to divert the crushed pharmaceutical raw materials and at the same time slow down the flow rate of the diverted pharmaceutical raw materials. In other words, powder is generated after the pharmaceutical raw materials are crushed, and dust is easily generated when the powder gathers and falls rapidly.

[0025] The top inlet of the screw conveyor 5 is connected to the bottom outlet of the air shutoff 4, and the above-mentioned diverted and slow-flowing pharmaceutical raw materials fall into the screw conveyor 5 in turn. The screw conveyor 5 adopts a conventional outer cylinder and a conveying auger structure located inside the outer cylinder. The rotation of the conveying auger can transmit the crushed pharmaceutical raw materials at a low speed.

[0026] The heating jacket 6 is sleeved on the outside of the screw conveyor 5, and an electric heating wire is sleeved inside the heating jacket 6. The heating jacket 6 heats the outer wall of the screw conveyor 5 to dry the pharmaceutical raw materials being transported and diverted. The top of the outer wall of the screw conveyor 5 is fixedly connected to the bottom of the exhaust pipe 7, and the water vapor in the transported pharmaceutical raw materials will be discharged upward through the exhaust pipe 7 to achieve drying of the pharmaceutical raw materials.

[0027] In this embodiment, the air lock 4 includes an outer shell 41 and a rotating shaft 42 located in the outer shell 41, and the rotating shaft 42 is fixedly connected with circumferentially evenly distributed partitions 421 and baffles 422 located at both ends of the partitions 421. The top of the outer shell 41 is fixedly connected with a discharge square tube 411 connected to the discharge pipe 3, and the outside of the outer shell 41 is fixedly connected with a drive motor, and the output shaft of the drive motor and one end of the rotating shaft 42 are fixedly connected. A transfer space is formed between adjacent partitions 421. A transfer space can transfer a small amount of crushed pharmaceutical raw materials. This transfer space is in a relatively closed state when located in the outer shell 41. This relatively closed state can effectively avoid high-speed airflow and prevent dust problems.

[0028] Furthermore, the two sides of the discharge square tube 411 are connected with impact rods 8 for upward and downward sliding movement, the filter screen 2 and the inner wall of the crushing box 1 are elastically connected for upward and downward sliding movement, the top of the impact rod 8 extends to the bottom of the filter screen 2 and its bottom and the outer peripheral wall of the baffle plate 422 are rollingly matched, and when the baffle plate 422 rotates, the impact rod 8 will vibrate, and this vibration will be transmitted to the filter screen 2, and the filter screen 2 will shake and shake off the blockage in its mesh hole, thereby achieving the effect of anti-blocking filtration.

[0029] Specifically, a roller 81 is provided at the bottom of the impact rod 8, and the outer peripheral wall of the roller 81 is fixedly provided with a pad 811 evenly distributed in the circumferential direction, and the outer peripheral wall of the baffle plate 422 is fixedly sleeved with a rubber ring 4221. The outer peripheral walls of the roller 81 and the rubber ring 4221 are against each other. When the baffle plate 422 rotates, under the action of the pad 811, the roller 81 will shake, and then drive the impact rod 8 to hit the filter screen 2.

[0030] The two side walls of the discharge square tube 411 are fixedly connected with a guide sleeve 4111 which is sleeved on the outside of the impact rod 8, the middle part of the bottom of the filter screen 2 is fixedly connected with the support shaft 21, the inner wall of the discharge pipe 3 is fixedly connected with a crossbeam 31, and a guide tube 311 which is sleeved on the outside of the support shaft 21 is fixedly provided on the crossbeam 31, the bottom of the support shaft 21 is fixedly connected with a baffle 9, and a return spring 101 is sleeved on the support shaft 21 and is located between the baffle 9 and the guide tube 311. The function of the return spring 101 is to apply a downward elastic thrust to the support shaft 21.

[0031] In this embodiment, the exhaust pipe 7 is conical with the small end facing upwards. The function of the exhaust pipe 7 is to discharge water vapor to the outside, and its conical structure can reduce the amount of small amounts of drug raw materials discharged in layers. The mouth of the exhaust pipe 7 is provided with filter cotton 102, which plays a role in blocking dust from being discharged.

[0032] When using this all-in-one machine, first open the cover on the top of the crushing box 1, then put the block of pharmaceutical raw materials into the crushing box 1, start the transmission motor on the top of the crushing box 1, and the crushing knife in the crushing box 1 rotates at high speed to crush the pharmaceutical raw materials. The crushed pharmaceutical raw materials are filtered by the filter screen 2 and fall downward. The fallen pharmaceutical raw materials fall into the air lock 4, and the air lock 4 is started. The shaft 42 rotates, and the space formed by the adjacent partitions 421 will divert the falling crushed pharmaceutical raw materials, and then fall into the screw conveyor 5, and the screw conveyor 5 is started. The pharmaceutical raw materials in the screw conveyor 5 are axially transmitted, and the heating sleeve 6 heats the continuously transmitted pharmaceutical raw materials. The evaporated water vapor of the pharmaceutical raw materials after being heated will float up and be discharged outward through the exhaust pipe 7.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
