Description

Technical Field

[0001] The utility model relates to the technical field of drug delivery, in particular to an intermediate drug feeding device. Background Art

[0002] The intermediate drug feeding device is a device used for feeding operations in the pharmaceutical industry. It is mainly used to accurately add the intermediate substances required for the reaction into the reaction system during the drug synthesis process. This device plays an important role in the pharmaceutical process, especially in continuous and automated production processes. It can improve the accuracy, efficiency and safety of the feeding process.

[0003] Existing intermediate drug feeding devices are unable to perform diversion, which will lead to a series of disadvantages, especially in the feeding process of granular solid intermediates. When the solid intermediate enters the reactor or mixing device through a single conveying pipe, the friction and accumulation between the particles may cause the particles to block the pipe. As the amount of particles increases, the blockage may gradually worsen, and eventually lead to complete blockage of the conveying pipe, making it impossible to continue feeding subsequent intermediates. The particle blockage will cause feeding interruption and force the production line to stop, which will reduce production efficiency and capacity. Utility Model Content

[0007] Preferably, three groups of diversion ports are provided at the bottom of the main body of the feeding device, and the bottom of each group of diversion ports is connected to three groups of spiral conveying bins, so that the material can enter the reaction system from different directions, which can more evenly distribute the material, reduce the situation where the local concentration is too high or too low, and is conducive to the uniform progress of the reaction. The diversion design can reduce the flow rate of the material in a single pipeline, reduce the possibility of material accumulation and blockage, and thus improve the stability and reliability of the system.

[0008] Preferably, the transmission mechanism includes a mounting plate mounted on the outer wall of the rear end of the diversion port, a motor mounted on the outer wall of the mounting plate, a first pulley connected to the output end of the motor, a belt wrapped around the first pulley, a second pulley wrapped around the other end of the belt, and a rotating shaft connected to the outer wall of the second pulley, allowing materials to be transported quickly and evenly through the multi-component diversion ports, thereby speeding up the feeding speed and improving production efficiency.

[0009] Preferably, the diameter of the first pulley is set to be larger than the diameter of the second pulley, and the transmission mechanism is provided with three groups corresponding to the diversion ports, so that under the same power, the torque generated by the second pulley is greater, thereby increasing the conveying force of the screw conveyor and improving the material conveying efficiency.

[0010] Preferably, the rotating shaft is connected to the spiral conveying bin, and two sets of clamping mechanisms are symmetrically connected on the mounting plate, which can balance the clamping force and ensure that the motor does not produce deviation or vibration during rotation, thereby improving the stability and service life of the equipment.

[0011] Preferably, the clamping mechanism includes a slot provided in the mounting plate, a slide groove provided in the slot, a slider slidably connected to the slide groove, a moving block connected to the slider and plugged into the slot, a spring provided in the slide groove, a clamping plate installed on the outer wall of the top end of the moving block, and a pull rod installed on the outer wall of the clamping plate.

[0012] Preferably, one end of the spring is connected to the outer wall of the slider, and the other end of the spring is connected to the inner wall of the slide groove, so that the motor can be easily removed from the mounting plate, which is convenient for maintenance and replacement, while ensuring the safety of the operator.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the present invention, the device is provided with multiple diversion ports, so that the granular solid intermediates can enter the spiral conveying bin from different directions, avoiding high-concentration accumulation in a single conveying pipeline, thereby significantly reducing the friction and accumulation between the particles and reducing the risk of particles blocking the pipeline.

[0015] 2. In the present invention, due to the diversion design, even if part of the conveying pipeline is blocked, the other pipelines can still continue to work, ensuring the continuity of feeding and avoiding feeding interruption and production line stoppage caused by blockage. Through diversion and efficient spiral conveying mechanism, the device can speed up the delivery speed of intermediates and improve feeding efficiency, thereby improving overall production efficiency and capacity.

[0016] 3. In the present invention, the design of the clamping mechanism ensures the stability of the motor during operation, reduces potential risks caused by vibration or deviation, improves the safety of the operator, allows for easy clamping and removal of the motor, and when the motor is damaged and needs to be replaced, the operation can be carried out quickly, reducing maintenance time and downtime.

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] See also Figure 1-Figure 5The utility model provides a technical solution: an intermediate drug feeding device, comprising: a feeding device body 1, the feeding device body 1 includes a plurality of group diversion ports 2 opened at the bottom, the lower end of the diversion port 2 is connected to a spiral conveying bin 3, the bottom end of the spiral conveying bin 3 is connected to a discharge port 4, and the rear end of each group of diversion ports 2 is provided with a group of transmission mechanisms 5, and the transmission mechanism 5 is provided with a clamping mechanism 6;

[0026] The transmission mechanism 5 drives the material in the spiral conveying bin 3 to advance, and the clamping mechanism 6 clamps and fixes the components of the transmission mechanism 5. Three groups of diversion ports 2 are provided at the bottom end of the feeding device body 1. The bottom end of each group of diversion ports 2 is connected to the three groups of spiral conveying bins 3, so that the material can enter the reaction system from different directions. This can more evenly distribute the material, reduce the situation where the local concentration is too high or too low, and is conducive to the uniform progress of the reaction. The diversion design can reduce the flow of materials in a single pipeline, reduce the possibility of material accumulation and blockage, and thus improve the stability and reliability of the system.

[0027] like Figure 3 and Figure 4 As shown, the transmission mechanism 5 includes a mounting plate 51 mounted on the outer wall of the rear end of the diversion port 2, a motor 52 mounted on the outer wall of the mounting plate 51, a first pulley 53 connected to the output end of the motor 52, a belt 54 wound around the first pulley 53, a second pulley 55 wound around the other end of the belt 54, and a rotating shaft 56 connected to the outer wall of the second pulley 55.

[0028] The diameter of the first pulley 53 is set to be larger than the diameter of the second pulley 55, so that under the same power, the torque generated by the second pulley is greater, thereby increasing the conveying force of the screw conveyor and improving the material conveying efficiency. The transmission mechanism 5 is provided with three groups corresponding to the diversion port 2; the rotating shaft 56 is connected to the screw conveying bin 3, and two groups of clamping mechanisms 6 are symmetrically connected to the mounting plate 51, which can balance the clamping force and ensure that the motor will not generate deviation or vibration during rotation, thereby improving the stability and service life of the equipment.

[0029] like Figure 5 As shown, the clamping mechanism 6 includes a slot 61 provided in the mounting plate 51, a slide groove 62 provided in the slot 61, a slider 63 slidingly connected to the slide groove 62, a moving block 64 connected to the slider 63 and plugged into the slot 61, a spring 65 provided in the slide groove 62, a clamping plate 66 installed on the outer wall of the top end of the moving block 64, and a pull rod 67 installed on the outer wall of the clamping plate 66. One end of the spring 65 is connected to the outer wall of the slider 63, and the other end of the spring 65 is connected to the inner wall of the slide groove 62.

[0030] The method of use and working principle of this device: Before the feeding device body 1 is put into operation, the three motors 52 are started, so that the motors 52 drive the first pulley 53 to rotate, and the first pulley 53 drives the second pulley 55 to rotate synchronously through the belt 54, and the second pulley 55 drives the rotating shaft 56 to rotate synchronously, and the rotating shaft 56 drives the screw conveyor in the screw conveying bin 3 to rotate and push the material, and push the material to the discharge port 4 to flow out;

[0031] When the motor 52 is damaged due to long-term use and needs to be replaced, the staff only needs to pull the pull rod 67 outward, so that the pull rod 67 drives the clamping plate 66 to move outward, and the clamping plate 66 drives the moving block 64 to slide outward from the slot 61. The moving block 64 slides outward in the slide groove 62 through the slider 63. During the sliding process, the spring 65 is squeezed to produce deformation, and finally the clamping plate 66 is separated from the outer wall of the motor 52, and then the motor 52 is removed to complete the disassembly.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
