Elevators are one of the key conveying equipment. Existing elevators have the problem of raw material residue when applied to capsule drug production. Granular raw materials are easily left on the inner wall of the conveying channel of traditional elevators, which is difficult to clean. When changing raw materials later, cross-contamination between different raw materials is likely to occur, which does not meet the hygiene standards for capsule drug production.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1-8 The present invention provides a technical solution: a lifting machine for producing granular raw materials, including a belt conveyor 1 and a supporting shell 2. The belt conveyor 1 is installed inside the supporting shell 2, and a conveying baffle 101 is installed on the belt conveyor 1. The support housing 2 is equipped with a dust blowing and cleaning mechanism 3, which blows air from below the belt conveyor 1. The support housing 2 is equipped with an interception component 4, which intercepts the powder blown down by the dust blowing and cleaning mechanism 3. The dust removal mechanism 3 includes an inclined baffle plate 301, which is installed inside the support housing 2. The top of the inclined baffle plate 301 is close to the bottom of the top of the belt conveyor 1. A diversion channel 305 is fixedly installed on the outer wall of the inclined baffle plate 301 facing the belt conveyor 1. An air nozzle 306 is connected to the diversion channel 305. There are three diversion channels 305, and the air nozzles 306 on the three diversion channels 305 face different directions. When the belt conveyor 1 conveys granular raw materials, the raw materials remaining on the belt conveyor 1 and the conveying baffle 101 will be blown off into the support housing 2 by the airflow blown out by the air nozzles 306. The interception component 4 intercepts the raw materials to prevent them from flowing out with the airflow. Because the three sets of air nozzles 306 face different directions, the blown airflow can form turbulence at the belt conveyor 1. The turbulence can better blow off the raw materials remaining on the belt conveyor 1 and the conveying baffle 101. The soot blowing cleaning mechanism 3 also includes an air inlet chamber 302 and an air pump 303. The air inlet chamber 302 is fixedly installed on the inclined baffle plate 301. The interior of the air inlet chamber 302 is connected to the interior of the diversion channel 305. The air pump 303 is fixedly installed on the inclined baffle plate 301. The air outlet end of the air pump 303 is connected to an air inlet pipe 304. The top end of the air inlet pipe 304 is connected to the interior of the air inlet chamber 302. The air inlet end of the air pump 303 is connected to an air inlet assembly 307. The air inlet end of the air inlet assembly 307 extends outside the supporting housing 2. The air pump 303 generates a high-pressure airflow. The airflow enters the air inlet chamber 302 from the air inlet pipe 304, then enters the diversion channel 305 from the air inlet chamber 302, and finally blows out from the jet nozzle 306. The air intake assembly 307 includes an air intake channel 3071. The front end of the air intake channel 3071 extends outside the support housing 2, and the rear end of the air intake channel 3071 is connected to the air intake end of the air pump 303 through a pipe. A filter element 3072 is installed inside the air intake channel 3071, and a dustproof net 3073 is installed at the front end of the air intake channel 3071. The air intake channel 3071 is set to connect to the air intake end of the air pump 303, and at the same time, it is used to install the filter element 3072 and the dustproof net 3073. The dustproof net 3073 is set to prevent dust, and the filter element 3072 is set to further filter the air to ensure that the air entering the soot blowing and cleaning mechanism 3 is clean enough. The interception assembly 4 includes three corrugated screen plates: a first corrugated screen plate 401, a second corrugated screen plate 402, and a third corrugated screen plate 403. All three are fixed within the supporting housing 2 and are arranged sequentially from left to right. The tops of the corrugated screen plates 401, 402, and 403 are connected to the belt conveyor. There is a gap between the lower surfaces of machine 1, and the screen holes of the wave-shaped screen plate 1 401, wave-shaped screen plate 2 402, and wave-shaped screen plate 3 403 are successively smaller. The wave-shaped screen plate 1 401, wave-shaped screen plate 2 402, and wave-shaped screen plate 3 403 are set to intercept the raw materials blown down by the airflow. The wave shape of the wave-shaped screen plate 1 401, wave-shaped screen plate 2 402, and wave-shaped screen plate 3 403 can buffer the airflow and better intercept the raw materials. A discharge guide plate 5 is fixedly installed on the top left end of the supporting housing 2. The top opening of the discharge guide plate 5 is located below the left end of the belt conveyor 1. The discharge guide plate 5 is set to receive the raw material output from the left end of the belt conveyor 1 and then guide the raw material to the next device. A tripod 6 is fixedly installed at the bottom of the discharge guide plate 5. The tripod 6 is fixedly installed on the outer wall of the supporting shell 2. There are three tripods 6, which are evenly distributed at the bottom of the discharge guide plate 5. The tripods 6 are used to support the discharge guide plate 5. The front of the supporting shell 2 is provided with a material inlet 9. There are three material inlets 9, which are located between the inclined baffle plate 301 and the first wavy screen plate 401, between the first wavy screen plate 401 and the second wavy screen plate 402, and between the second wavy screen plate 402 and the third wavy screen plate 403, respectively. The material inlets 9 are used to take out the raw materials inside the supporting shell 2. A stop 10 is snapped into the material inlet 9. A magnetic plate 11 is fixedly installed on the front of the stop 10. The magnetic plate 11 is magnetically attached to the support housing 2. When the material is not being taken out, the stop 10 is used to block the material inlet 9, and the magnetic plate 11 is used to fix the stop 10. A collection box 8 is provided on the right side of the supporting shell 2. The top opening of the collection box 8 is lower than the right end of the belt conveyor 1. The collection box 8 is provided to catch the raw materials falling from the right end of the belt conveyor 1. A feed hopper 7 is fixedly installed on the top of the supporting shell 2. The bottom opening of the feed hopper 7 is located above the belt conveyor 1. The feed hopper 7 is set up to feed granular raw materials onto the belt conveyor 1.

[0019] Working principle: During use, granular raw materials are fed into the feed hopper 7. The raw materials fall from the bottom opening of the feed hopper 7 onto the belt conveyor 1, where they are lifted and conveyed by the belt conveyor 1 and the conveying baffle 101 until they reach the left end of the belt conveyor 1. At this point, under the action of gravity and inertia, the raw materials slide off the belt conveyor 1 into the discharge guide plate 5, and are then guided by the discharge guide plate 5 to the next device. At the same time, the air pump 303 is turned on, drawing in air and pressurizing it. The airflow is conveyed into the air inlet chamber 302, and then enters the diversion channel 305 from the air inlet chamber 302. It is then blown from the jet nozzle 306 onto the lower surface of the belt conveyor 1, blowing off the raw materials remaining on the belt conveyor 1 and the conveying baffle 101. The blown-off raw materials are intercepted when passing through the corrugated screen plate 1 401, corrugated screen plate 2 402, and corrugated screen plate 3 403, which can effectively avoid the problem of raw materials remaining on the belt conveyor 1 and the conveying baffle 101.
