[0002] With the advancement of science and technology, the development of traditional Chinese medicine has increased year by year. Therefore, the residues of traditional Chinese medicine after extraction are increasing. If the pharmaceutical factory simply piles the residues in the open air, the residues will gradually ferment and rot, polluting the environment. How to reasonably utilize the residues of traditional Chinese medicine is an important issue that needs to be solved urgently.

[0003] The current resource utilization method of medicinal residues is to process the medicinal residues into biomass fuel through a combination of processes such as dehydration pretreatment, crushing and extrusion molding. The medicinal residue processing system includes dehydration equipment, crushing equipment and molding equipment. The medicinal residues contain a lot of water after boiling. It is necessary to first pass through the dehydration equipment to dry the moisture content of the medicinal residues to a moisture content that meets the biomass fuel molding standard, and then transport the dried medicinal residues to the crushing equipment to crush the medicinal residues into powder. Then the powdered medicinal residues are transported to the molding equipment, and the molding equipment molds the medicinal residues into strips or blocks of biomass fuel.

[0004] However, the dehydration equipment, crushing equipment and molding equipment in the drug residue processing system need to be purchased separately by the pharmaceutical factory, and multiple devices make the drug residue processing system occupy a large space, which makes the cost of drug residue resource utilization high. Summary of the invention

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1-5 This application is described in further detail.

[0044] The present application discloses a system for recycling drug residue solid waste resources, referring to Figure 1 and Figure 2The drug residue solid waste resource utilization system includes a frame 2, a feeding assembly 9, a crushing assembly 6, a molding assembly 7 and a material transport assembly 8. The crushing assembly 6 is arranged inside the crushing chamber 3, the molding assembly 7 includes a molding inner mold 73 and a molding outer mold 71, and the material transport assembly 8 includes a sealing shell 81. The molding inner mold 73, the molding outer mold 71 and the sealing shell 81 are sequentially arranged on the frame 2 from the inside to the outside. The crushing chamber 3 is arranged inside the molding inner mold 73, so that the molding inner mold 73 forms the side wall of the crushing chamber 3. A molding chamber 4 is arranged between the molding inner mold 73 and the molding outer mold 71. The molding outer mold 71 and the molding inner mold 73 jointly form the side wall of the molding chamber 4. A material transport chamber 5 is arranged between the molding outer mold 71 and the sealing shell 81, and the molding outer mold 71 and the sealing shell 81 jointly form the side wall of the material transport chamber 5.

[0045] The feeding component 9 preliminarily crushes the medicinal residue and transports it to the crushing chamber 3. The crushing component 6 crushes the medicinal residue into granules, and then transports the granular medicinal residue to the molding chamber 4. The granular medicinal residue in the molding chamber 4 is dried to a moisture content that meets the moisture content of the medicinal residue that meets the biomass fuel molding standard. Then the molding component 7 extrude the granular medicinal residue into a rod shape, and the rod-shaped medicinal residue is transported to the transport chamber 5, and is transported by the transport component 8 to the next process processing place or the production personnel collect and process the rod-shaped medicinal residue.

[0046] Reference Figure 2 and Figure 3 The feeding assembly 9 includes a feeding hopper 91, a first squeezing roller 92, a second squeezing roller 94 and a fourth driving member 96.

The first squeezing roller 92 and the second squeezing roller 94 are both rotatably connected to the inside of the feeding hopper 91, and the rotation axes are parallel to each other. The outer wall of the first squeezing roller 92 is fixedly connected with a plurality of first crushing teeth 93 around the rotation axis of the first squeezing roller 92, and the outer wall of the second squeezing roller 94 is fixedly connected with a plurality of second crushing teeth 95 around the rotation axis of the second squeezing roller 94.

The driving gear is coaxially fixedly connected to the first squeezing roller 92, the driven gear is coaxially fixedly connected to the second squeezing roller 94, the output end of the motor is coaxially fixedly connected to the driving gear, and the output end of the motor can rotate to drive the first squeezing roller 92 and the second squeezing roller 94 to rotate towards each other at the same time.

[0047] After the medicinal residue is poured into the upper hopper 91, it falls between the first squeezing roller 92 and the second squeezing roller 94. The first squeezing roller 92 and the second squeezing roller 94 rotate towards each other, so that the first crushing teeth 93 and the second crushing teeth 95 bite the medicinal residue to preliminarily squeeze and crush the medicinal residue, and make the medicinal residue pass through the first crushing teeth 93 and the second crushing teeth 95 and discharge into the crushing chamber 3. The first crushing teeth 93 and the second crushing teeth 95 can bite the medicinal residue, thereby reducing the situation in which the medicinal residue is difficult to pass between the first squeezing roller 92 and the second squeezing roller 94 due to slipping. Preliminary squeezing and crushing of the medicinal residue can reduce the time for the crushing component to bite and crush it into particles, thereby improving the efficiency of medicinal residue crushing.

The inner molding mold 73 is fixedly connected to the frame 2. The outer molding mold 71 and the sealing shell 81 are both movably arranged on the frame 2 along the vertical direction. The outer molding mold 71 can be moved to fit with the inner molding mold 73, and the sealing shell 81 can be moved to fit with the outer molding mold 71.

[0049] Reference Figure 3 and Figure 4 The crushing assembly 6 includes a cutter 61 and a third driving member 62, the third driving member 62 is a motor, the third driving member 62 is mounted on the inner wall of the forming inner mold 73, the rotation axis of the output end of the third driving member 62 is arranged in the vertical direction, the cutter 61 includes an upper blade 611 and a lower blade 612, the lower blade 612 is bent downward and one end is fixedly connected to the output end of the third driving member 62, the upper blade 611 is arranged above the lower blade 612 and is bent upward, and one end of the upper blade 611 is fixedly connected to the output end of the third driving member 62. The forming inner mold 73 is provided with a plurality of second discharge holes 74 around its axis, so that the crushing chamber 3 is connected to the forming chamber 4 through the second discharge holes 74, and the outer wall of the forming inner mold 73 is provided with a plurality of sinks corresponding to the second discharge holes 74, and a stopper 75 is rotatably connected to the inner wall of the sink, and an elastic member 76 is connected between the stopper 75 and the inner wall of the sink, and the elastic member 76 is a torsion spring, and the stopper 75 can seal the second discharge hole 74. The inner molding mold 73 is provided with a plurality of molding holes 72 around its axis, so that the molding chamber 4 is connected with the material transport chamber 5 through the molding holes 72 . The molding holes 72 are located below the second discharge hole 74 . When the sealing shell 81 moves to fit with the outer molding mold 71 , the sealing shell 81 can seal the molding holes 72 .

[0050] When crushing the medicinal residue, the outer molding die 71 moves to fit with the inner molding die 73, so that the inner wall of the outer molding die 71 is pressed against the baffle 75, so that the baffle 75 seals the second discharge hole 74 under the joint action of the elastic member 76 and the outer molding die 71, and the sealing shell 81 moves to fit with the outer molding die 71. The medicinal residue falls into the inside of the crushing chamber 3 after passing through the feeding assembly 9, and water is added to the inside of the crushing chamber 3, and then the third driving member 62 drives the cutter 61 to rotate, so that the cutter 61 crushes the medicinal residue into particles. After the medicinal residue is crushed into particles, the cutter 61 keeps rotating, and the outer molding die 71 and the sealing shell 81 move at the same time, so that the baffle 75 can rotate until the second discharge hole 74 is opened, and the sealing shell 81 seals the molding hole 72. The cutter 61 rotates so that the granular medicinal residue carried by the water body pushes open the baffle 75 under the action of centrifugal force and enters the molding chamber 4 through the second discharge hole 74. After the medicinal residue is carried by the water body into the molding chamber 4, the water body is waited for to evaporate, so that the granular medicinal residue is dried until the moisture content of the medicinal residue meets the moisture content of the biomass fuel molding standard, thereby completing the crushing and drying of the medicinal residue.

[0051] The upper blade 611 and the lower blade 612 enable the cutter 61 to crush the medicinal residues at different positions when the cutter 61 rotates, thereby improving the crushing efficiency of the medicinal residues.

[0052] The inner molding die 73 is a truncated cone-shaped shell with an upward opening, and the diameter of the truncated cone-shaped shell gradually decreases from top to bottom, so that under the action of centrifugal force, the water body can carry the medicinal residues upward along the inner side wall of the inner molding die 73 to the second discharge hole 74, thereby reducing the accumulation of medicinal residues below the second discharge hole 74 and improving the utilization rate of the medicinal residues. The outer molding die 71 has the same shape as the inner molding die 73, so that the outer molding die 71 can be moved to fit with the inner molding die 73, and the sealing shell 81 has the same shape as the outer molding die 71, so that the sealing shell 81 can be moved to fit with the outer molding die 71.

[0053] Reference Figure 3 and Figure 5 The side wall of the molding outer mold 71 is provided with a plurality of drainage holes 10 around its axis. The drainage holes 10 are staggered with the molding holes 72. The drainage holes 10 are provided along the tangent direction of the molding outer mold 71. One end of the drainage hole 10 forms an opening at the top wall of the molding outer mold 71, and the other end forms an opening at the inner side wall of the bottom of the molding outer mold 71.

[0054] One end of the drainage hole 10 can be connected to an external water pump through a pipe. After the water and the medicinal residue enter the molding chamber 4, the water pump can pump the water out of the molding chamber 4, thereby increasing the drying speed of the medicinal residue and shortening the drying time of the medicinal residue.

[0055] Reference Figure 3The molding assembly 7 includes a second driving member 77, which is disposed below the sealing shell 81 and fixedly connected to the frame 2. The second driving member 77 is a cylinder, and the moving direction of the output end of the second driving member 77 is a vertical direction. The output end of the second driving member 77 passes through the sealing shell 81 and is fixedly connected to the molding outer mold 71. The material transport assembly 8 includes a first driving member 82, which is disposed below the sealing shell 81 and fixedly connected to the frame 2. The moving direction of the output end of the first driving member 82 is a vertical direction. The output end of the first driving member 82 is fixedly connected to the bottom wall of the sealing shell 81, and a first discharge hole 83 is provided on the side wall at the bottom of the sealing shell 81.

[0056] After the residue is dried to a moisture content that meets the biomass fuel molding standard, the first driving member 82 drives the sealing shell 81 to move downward to release the sealing of the sealing shell 81 on the molding hole 72, so that the molding chamber 4 is connected to the material transport chamber 5 through the molding hole 72, and then the second driving member 77 drives the molding outer mold 71 to move back and forth in the vertical direction, so that the molding outer mold 71 moves back and forth in the direction of approaching the molding inner mold 73 and away from the molding inner mold 73, so as to squeeze the granular residue in the molding chamber 4 through the molding hole 72 to form a rod-shaped residue. When the molding outer mold 71 moves in the direction of approaching the molding inner mold 73, the rod-shaped residue passes through the molding hole 72 and falls into the material transport chamber 5. When the molding outer mold 71 moves in the direction of away from the molding inner mold 73, the molding outer mold 71 pushes the rod-shaped residue inside the material transport chamber 5 so that the rod-shaped residue leaves the material transport chamber 5 through the first discharge hole 83, thereby completing the molding of the residue. After the rod-shaped medicinal residue leaves the transport chamber 5 , the rod-shaped medicinal residue is collected or transported to a processing location for the next process.

[0057] Reference Figure 3 The top of the side wall of the inner molding die 73 is detachably connected with a baffle 78 by bolts. When the outer molding die 71 moves toward the inner molding die 73, the baffle 78 can close the end of the top opening of the molding chamber 4, thereby reducing the drug residue squeezed out from the end of the top opening of the molding chamber 4 and improving the utilization rate of the drug residue and the molding efficiency.

[0058] The implementation principle of a drug residue solid waste resource utilization system in an embodiment of the present application is: the molding outer mold 71 moves to abut against the molding inner mold 73, thereby sealing the second discharge hole 74, and the sealing shell 81 moves to abut against the molding outer mold 71, thereby sealing the molding hole 72, and then the drug residue and water are transported to the crushing chamber 3, and the cutter 61 rotates to crush the drug residue into particles, thereby completing the crushing of the drug residue. Then the cutter 61 continues to rotate, and the sealing shell 81 and the molding outer mold 71 move simultaneously, so that the crushing chamber 3 is connected with the molding chamber 4 through the second discharge hole 74. The water body transports the granular medicinal residue to the molding chamber 4 under the action of centrifugal force. After the medicinal residue in the molding chamber 4 is dried to a moisture content that meets the moisture content of the medicinal residue in accordance with the biomass fuel molding standard, the molding outer mold 71 reciprocates in the direction of approaching and moving away from the molding inner mold 73, so that the granular medicinal residue is squeezed through the molding hole 72 to be formed into rod-shaped medicinal residue. After the rod-shaped medicinal residue is formed, it falls into the transport chamber 5. When the molding outer mold 71 moves in the direction away from the molding inner mold 73, it pushes the rod-shaped medicinal residue out of the transport chamber 5 from the first discharge hole 83, thereby completing the medicinal residue molding process.

[0059] The multiple processes of crushing, drying and molding of medicinal residues are integrated into one device, and the pharmaceutical factory does not need to purchase different processing equipment for different processes. In addition, the molding inner mold 73, the molding outer mold 71 and the sealing shell 81 of the equipment are arranged from the inside to the outside, and the crushing chamber 3 for implementing the crushing process is arranged inside the molding inner mold 73, and the molding chamber 4 for implementing the molding process and the drying process is arranged between the molding inner mold 73 and the molding outer mold 71, thereby reducing the situation where multiple devices occupy a large space and reducing the cost of resource utilization of medicinal residues.

[0061] S1, the outer molding die 71 moves to fit with the inner molding die 73, so that the outer molding die 71 abuts against the blocking cover 75, the blocking cover 75 closes the second discharge hole 74, the sealing shell 81 moves to fit with the outer molding die 71, so that the sealing shell 81 closes the molding hole 72, and then the medicine residue is poured into the upper hopper 91, the first squeezing roller 92 and the second squeezing roller 94 rotate towards each other, so that the first crushing teeth 93 and the second second crushing teeth 95 preliminarily crush the medicine residue and transport it to the crushing chamber 3, and water is added to the crushing chamber 3, and the third driving member 62 drives the cutter 61 to rotate to crush the medicine residue into particles;

[0062] S2, the cutter 61 keeps rotating, and the outer molding die 71 and the sealing shell 81 simultaneously move to separate the outer molding die 71 from the inner molding die 73, so that the crushing chamber 3 is connected with the molding chamber 4 through the second discharge hole 74, and the sealing shell 81 closes the molding hole 72, so that the water body transports the granular medicinal residue to the molding chamber 4 through the second discharge hole 74, and then the cutter 61 stops rotating, waiting for the water body inside the molding chamber 4 to evaporate until the water content of the granular medicinal residue meets the water content of the biomass fuel molding standard;

[0063] S3, the molding outer mold 71 moves back and forth in the direction of approaching and moving away from the molding inner mold 73, so that the granular medicinal residue in the molding chamber 4 is extruded into a rod shape through the molding hole 72 and falls into the transport chamber 5. When the molding outer mold 71 moves in the direction away from the molding inner mold 73, the molding outer mold 71 pushes the rod-shaped medicinal residue that falls into the transport chamber 5 away from the transport chamber 5 through the first discharge hole 83. The rod-shaped medicinal residue leaving the transport chamber 5 is collected and transported to the processing location of the next process.
