Description

Technical Field

[0001] This invention relates to a separation device for intermediates of anthelmintic drugs, belonging to the field of anthelmintic drug production. Background Technology

[0002] Anthelmintic drug intermediates are pharmaceutical intermediates synthesized from organic and inorganic substances through chemical reactions. These intermediates are typically used as raw materials in the drug synthesis process. Solid-liquid separation of anthelmintic drug intermediates is an important step in pharmaceutical processing, aiming to separate the desired solid intermediate product from the reaction mixture. This process usually utilizes separation equipment.

[0003] In existing technologies, some insecticide intermediate separation devices use a motor to drive a spiral blade to continuously push the material poured into the feed cylinder into a filter cylinder for solid-liquid separation. The separated solid material is pushed to the discharge hopper by the material entering later pushing the material entering earlier. The separated liquid material falls into the storage tank through several filter holes on the surface of the filter cylinder, thus achieving solid-liquid separation of the insecticide intermediate. However, this unloading method requires the material entering later to push the material entering earlier to unload the solid material. When no more material is poured into the feed cylinder, the material remaining in the filter cylinder will have difficulty moving towards the discharge hopper and will accumulate in the filter cylinder, resulting in poor unloading effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a separation device for intermediates of anthelmintic drugs, thereby solving the problem mentioned in the background art where some anthelmintic drug intermediate separation devices require the later-entering material to push the earlier-entering material to unload the solid material. When no more material is poured into the conveying cylinder, the material remaining in the filter cylinder will have difficulty moving towards the discharge bin, and the material will accumulate in the filter cylinder, resulting in poor unloading effect.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a separation device for intermediates of insect repellent drugs, comprising a storage tank, a filter cylinder fixedly connected to the inner wall of the storage tank, a first pressure plate fixedly connected to the inner wall of the filter cylinder, a second pressure plate fixedly connected to the inner wall of the filter cylinder below the first pressure plate, a swing shaft rotatably connected to the inner wall of the filter cylinder between the first pressure plate and the second pressure plate, a motor fixedly connected to one end of the swing shaft extending out of the storage tank, two dynamic pressure plates fixedly connected to the surface of the swing shaft, a discharge assembly provided at the bottom of the filter cylinder, and a cleaning assembly provided inside the swing shaft;

[0006] The discharge assembly includes a discharge port at the bottom of the filter cylinder, a discharge trough fixedly connected to the inner wall of the storage tank below the discharge port, an electric push rod fixedly connected to the inner wall of the discharge trough, a cap fixedly connected to the top of the electric push rod, the cap being movably connected to the discharge port, a clearance groove provided in the second pressure plate, a compression spring fixedly connected to the inner wall of the clearance groove, the compression spring being fixedly connected to the cap, a liquid outlet pipe fixedly connected to the bottom of the storage tank, and a discharge pipe fixedly connected to one side of the storage tank.

[0007] Furthermore, the cleaning assembly includes an air pump fixedly connected to the top of the liquid storage tank, an air supply pipe fixedly connected to one side of the air pump, the air supply pipe being rotatably connected to the swing shaft, an air supply chamber being opened inside the swing shaft, a plurality of air inlet chambers being opened inside the dynamic pressure plate, the air inlet chambers being connected to the air supply chambers, and a plurality of one-way valves being fixedly connected to the inner wall of the dynamic pressure plate near the filter cartridge.

[0008] Furthermore, a feed inlet is fixedly connected to the top of the filter cylinder, and a spiral blade is fixedly connected to the surface of the swing shaft below the feed inlet.

[0009] Furthermore, both the bottom of the liquid storage tank and the bottom of the discharge trough are inclined, and the bottom surface of the discharge trough is higher than the bottom surface of the liquid storage tank.

[0010] Furthermore, the inner wall of the discharge port is stepped, and the size of the cover is the same as the size of the discharge port.

[0011] Furthermore, the storage tank is fixedly connected to four corners at the bottom, and the bottom surfaces of the liquid outlet pipe and the discharge pipe are both higher than the bottom surfaces of the support feet.

[0012] The beneficial effects of this utility model are as follows: The motor and the swing shaft drive the two dynamic pressure plates to rotate synchronously. During this process, the first and second fixed pressure plates can continuously squeeze the material in the filter cylinder. The liquid material will fall from the filter cylinder into the storage tank. After the solid-liquid separation is completed, the electric push rod will move the cover away from the discharge port. The solid material will fall from the discharge port into the discharge trough. Finally, the liquid outlet pipe and the discharge pipe can be opened to obtain the separated solid material and liquid material, thereby realizing the separation of the intermediate. The compression spring effectively improves the sealing between the cover and the discharge port.

[0013] The air pump can sequentially deliver gas to the air delivery pipe, air delivery chamber and air inlet chamber, so that the air can be sprayed onto the filter cartridge while the motor drives the dynamic pressure plate to rotate, thus cleaning the filter cartridge. The one-way valve can prevent material from entering the air inlet chamber during the solid-liquid separation process. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a separation device for intermediates of insect repellent drugs, including a storage tank 1, a filter cylinder 2 fixedly connected to the inner wall of the storage tank 1, a first pressure plate 3 fixedly connected to the inner wall of the filter cylinder 2, a second pressure plate 4 fixedly connected to the inner wall of the filter cylinder 2 below the first pressure plate 3, a swing shaft 5 rotatably connected to the inner wall of the filter cylinder 2 between the first pressure plate 3 and the second pressure plate 4, a motor 6 fixedly connected to one end of the swing shaft 5 extending out of the storage tank 1, two dynamic pressure plates 7 fixedly connected to the surface of the swing shaft 5, a discharge component 8 provided at the bottom of the filter cylinder 2, and a cleaning component 9 provided inside the swing shaft 5;

[0023] The discharge assembly 8 includes a discharge port 81 located at the bottom of the filter cylinder 2. A discharge trough 82 is fixedly connected to the inner wall of the storage tank 1 below the discharge port 81. An electric push rod 83 is fixedly connected to the inner wall of the discharge trough 82. A cover 84 is fixedly connected to the top of the electric push rod 83. The cover 84 and the discharge port 81 are movably connected. A clearance groove 85 is provided in the second pressure plate 4. A compression spring 86 is fixedly connected to the inner wall of the clearance groove 85. The compression spring 86 and the cover 84 are fixedly connected. A liquid outlet pipe 87 is fixedly connected to the bottom of the storage tank 1. A discharge pipe 88 is fixedly connected to one side of the storage tank 1.

[0024] The motor 6 and the swing shaft 5 drive the two dynamic pressure plates 7 to rotate synchronously. During this process, the first fixed pressure plate 3 and the second fixed pressure plate 4 can continuously squeeze the material in the filter cylinder 2. The liquid material will fall from the filter cylinder 2 into the storage tank 1. After the solid-liquid separation is completed, the electric push rod 83 will move the cover 84 away from the discharge port 81. The solid material will fall from the discharge port 81 into the discharge trough 82. Finally, the liquid outlet pipe 87 and the discharge pipe 88 can be opened to obtain the separated solid and liquid materials, thus realizing the separation of the intermediate. The compression spring 86 effectively improves the sealing between the cover 84 and the discharge port 81.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: the cleaning component 9 includes an air pump 91 fixedly connected to the top of the liquid storage tank 1, an air supply pipe 92 fixedly connected to one side of the air pump 91, the air supply pipe 92 being rotatably connected to the swing shaft 5, an air supply chamber 93 being opened inside the swing shaft 5, and several air inlet chambers 94 being opened inside the dynamic pressure plate 7, the air inlet chambers 94 being connected to the air supply chambers 93, and several one-way valves 95 being fixedly connected to the inner wall of the dynamic pressure plate 7 near the filter cartridge 2. The air pump 91 can sequentially deliver gas to the air supply pipe 92, the air supply chamber 93, and the air inlet chambers 94, thereby cleaning the filter cartridge 2 by spraying air towards it while the motor 6 drives the dynamic pressure plate 7 to rotate. The one-way valves 95 prevent material from entering the air inlet chambers 94 during solid-liquid separation.

[0026] A feed inlet 10 is fixedly connected to the top of the filter cylinder 2, and a spiral blade 11 is fixedly connected to the surface of the swing shaft 5 below the feed inlet 10. When the material is poured into the filter cylinder 2 through the feed inlet 10, the motor 6 will drive the spiral blade 11 to rotate synchronously to continuously push the material in the filter cylinder 2 towards the discharge pipe 88, thus completing the feeding of the intermediate.

[0027] Both the bottom of the storage tank 1 and the bottom of the discharge trough 82 are inclined, with the bottom surface of the discharge trough 82 being higher than the bottom surface of the storage tank 1. The inclined bottom of the storage tank 1 and the bottom of the discharge trough 82 can guide the solid and liquid phase materials to the discharge pipe 88 and the liquid discharge pipe 87 respectively, facilitating the unloading of the separated intermediate. The fact that the bottom surface of the discharge trough 82 is higher than the bottom surface of the storage tank 1 prevents the discharge trough 82 from obstructing the accumulation of liquid phase material on the inner wall of the bottom of the storage tank 1.

[0028] The inner wall of the discharge port 81 is stepped, and the size of the cap 84 is the same as that of the discharge port 81. The stepped inner wall of the discharge port 81 and the size of the cap 84 being the same as that of the discharge port 81 ensure the sealing between the cap 84 and the discharge port 81, preventing leakage of the intermediate from the discharge port 81 during solid-liquid separation.

[0029] Support legs 12 are fixedly connected to the four corners of the bottom of the liquid storage tank 1. The bottom surfaces of the liquid outlet pipe 87 and the material outlet pipe 88 are both higher than the bottom surfaces of the support legs 12. The support legs 12 provide support for the device, and the fact that the bottom surfaces of the liquid outlet pipe 87 and the material outlet pipe 88 are higher than the bottom surfaces of the support legs 12 facilitates the unloading of the separated intermediates.

[0030] Detailed Implementation: The intermediate is poured into the filter cylinder 2. The motor 6 drives the swing shaft 5 connected to it to rotate inside the filter cylinder 2, thereby driving the two dynamic pressure plates 7 connected to the surface of the swing shaft 5 to rotate synchronously. During this process, the first fixed pressure plate 3 and the second fixed pressure plate 4 fixed to the inner wall of the filter cylinder 2 can continuously squeeze the material inside the filter cylinder 2. The liquid material will fall from the filter cylinder 2 into the storage tank 1. After the solid-liquid separation is completed, the electric push rod 83 is activated to push the cover 84 away from the discharge port 81, thereby causing the cover 84 to move along the opening at the first... The clearance groove 85 in the two fixed pressure plates 4 moves in the same direction and squeezes the compression spring 86. At this time, the two moving pressure plates 7 will push the solid material to the discharge port 81. The solid material will fall from the discharge port 81 into the discharge trough 82. Finally, the liquid outlet pipe 87 and the discharge pipe 88 can be opened to obtain the separated solid material and liquid material, thereby realizing the separation of the intermediate. In this way, the compression spring 86 can squeeze the cap 84 during the solid-liquid separation process so that it is tightly attached to the inner wall of the discharge port 81, thereby effectively improving the sealing between the cap 84 and the discharge port 81.

[0031] When the filter cartridge 2 becomes clogged, the air pump 91 is activated. The air pump 91 delivers gas to the air delivery chamber 93 located in the swing shaft 5 through the air delivery pipe 92. Then, the gas will enter the air inlet chamber 94 located in the dynamic pressure plate 7, which is connected to the air delivery chamber 93. This allows the gas to be sprayed onto the filter cartridge 2 while the motor 6 drives the dynamic pressure plate 7 to rotate, thus cleaning the filter cartridge 2 and preventing material from clogging it. The one-way valve 95 prevents material from entering the air inlet chamber 94 during the solid-liquid separation process.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
