Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical production accessories and equipment, specifically a highly efficient and convenient activated carbon filtration device. Background Technology

[0002] Pharmaceutical intermediates are essentially chemical raw materials or products used in drug synthesis processes. These chemical products do not require a drug production license and can be produced in ordinary chemical plants. As long as they meet certain standards, they can be used in drug synthesis. With the increasing application of pharmaceutical intermediates, ensuring their production quality has become a growing concern. Consequently, material filtration equipment for pharmaceutical intermediate production is being used more and more widely.

[0003] In the prior art, before producing a drug, it is necessary to filter out impurities from the raw materials to prevent them from mixing with the raw materials and affecting the drug's efficacy. The existing method for filtering impurities from the raw materials is to place the raw materials inside a sieve tray and have the operator continuously shake the sieve tray to filter and separate the impurities from the raw materials.

[0004] Existing technologies still have some shortcomings. The method of filtering and screening pharmaceutical raw materials by manually shaking the sieve not only consumes a lot of manpower and is inefficient, but also makes it easy for some impurities to not be accurately filtered out and remain inside the sieve, thus affecting the filtration effect on pharmaceutical raw materials. Therefore, we propose an efficient and convenient activated carbon filtration device. Utility Model Content

[0005] The purpose of this invention is to provide a highly efficient and convenient activated carbon filtration device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly efficient and convenient activated carbon filtration device, including a processing box;

[0007] A material discharge chute is located on the left side of the processing box;

[0008] The system includes a filter assembly housed inside the processing chamber. The filter assembly comprises grooves formed on the inner walls of both sides of the processing chamber. A drive motor is fixedly connected to the back of the processing chamber. An output shaft is fixedly connected to the output end of the drive motor, and the output shaft movably passes through the back of the processing chamber and extends into the interior of the processing chamber. A cam is fixedly connected to the outer wall of the other end of the output shaft. A pressing block is slidably connected to the bottom of the cam. A first filter frame is fixedly connected to the side wall of the pressing block. Slider blocks are fixedly connected to both sides of the first filter frame. Limit rods are slidably connected to the inner walls of the sliders. Both ends of the limit rods are fixedly connected to the inner walls of the grooves. A spring is fixedly connected to the top of the sliders, and the other end of the spring is fixedly connected to the top of the inner wall of the groove. Two support plates are movably connected to the center bottom of the first filter frame via two hinges. The other end of the support plate is movably connected to a brush plate via a hinge. A horizontal plate is slidably connected to the top of the brush plate, and a second filter frame is fixedly connected to the bottom of the horizontal plate. The outer wall of the second filter frame is fixedly connected to the inner wall of the processing box, and the bottom of the brush plate is slidably connected to the bottom of the inner wall of the second filter frame. By setting up the filter assembly, after the raw materials of the medicine are filtered through the first filter frame, they will fall into the interior of the second filter frame. The second filter frame can perform secondary filtration on the raw materials of the medicine. When the first filter frame vibrates up and down, the hinge will cause the support plate to rotate. After the horizontal plate limits the brush plate, it will cause the two brush plates to move along the inner wall of the second filter frame, thereby brushing the raw materials of the medicine inside the second filter frame and improving the filtration efficiency of the second filter frame for impurities in the raw materials of the medicine.

[0009] Preferably, the filtration assembly further includes an inclined filter plate fixedly connected to the inner wall of the processing box. The inclined filter plate is located below the second filter frame. A U-shaped frame is fixedly connected to the left side of the processing box. A collection frame is slidably connected to the bottom of the inner wall of the U-shaped frame. The collection frame is located to the lower left of the material drop chute. After the pharmaceutical raw material has been filtered through the second filter frame, it will fall onto the surface of the inclined filter plate. Under the guiding action of the inclined filter plate, the pharmaceutical raw material will be filtered again along the surface of the inclined filter plate and fall into the inside of the collection frame after filtration. The collection frame collects the pharmaceutical raw material, thereby completing the entire filtration process and improving the filtration effect of the pharmaceutical raw material.

[0010] Preferably, the processing box is further equipped with a purification component. The purification component includes a purification chamber fixedly connected to the top of the inner wall of the processing box. A U-shaped block is fixedly connected to the inner wall of the purification chamber. A T-shaped block is slidably connected to the inner side wall of the U-shaped block. An activated carbon adsorption layer is fixedly connected to the side wall of the T-shaped block. The bottom of the purification chamber has multiple through slots. By setting up the purification component, during the filtration of pharmaceutical raw materials, since the pharmaceutical raw materials may contain some irritating odors, in order to effectively absorb the odors generated during the filtration process, the activated carbon adsorption layer needs to adsorb the odors. First, the operator inserts the T-shaped blocks at both ends of the activated carbon adsorption layer into the U-shaped block, thereby assembling the activated carbon adsorption layer. When the processing box is filtering pharmaceutical raw materials, the activated carbon adsorption layer inside the purification chamber will adsorb the odors in the pharmaceutical raw materials, thereby improving the processing effect of the device on the pharmaceutical raw materials.

[0011] Preferably, the bottom of the processing box is fixedly connected with four support legs. The four support legs are equidistantly fixedly connected to the bottom of the four corners of the processing box. The four support legs at the bottom of the processing box can provide stable support for the processing box.

[0012] Preferably, the front of the processing box is hinged to a door, the inner wall of the door is fixedly connected to an observation window, and the front of the door is fixedly connected to a handle. With the door and handle on the front of the processing box, after the raw materials for the medicine are filtered, the operator can open the door by pulling the handle, thereby cleaning the impurities that remain inside the first and second filter frames after filtration. With the observation window inside the door, the operator can observe the filtration of the raw materials for the medicine inside the processing box from the outside during the filtration process.

[0013] Preferably, there are two brush plates, which are symmetrically distributed along the center plane of the second filter frame.

[0014] This invention provides a highly efficient and convenient activated carbon filtration device. This highly efficient and convenient activated carbon filtration device has the following beneficial effects:

[0015] (1) This efficient and convenient activated carbon filtration device, by setting up a filtration component, is used in the pharmaceutical production process to filter impurities in pharmaceutical raw materials to prevent impurities from mixing with the pharmaceutical raw materials and affecting the production effect of the pharmaceutical. In the process of filtering pharmaceutical raw materials, the operator first places the pharmaceutical raw materials inside the first filter frame, and the impurities in the pharmaceutical raw materials are initially filtered through the first filter frame. In order to avoid the pharmaceutical raw materials accumulating inside the first filter frame and affecting the filtration efficiency of the pharmaceutical, the operator turns on the drive motor to make the output shaft rotate. During the rotation of the output shaft, it can drive the cam to rotate. During the rotation of the cam, its bottom will squeeze the extrusion block, thereby pushing the first filter frame downward. During the downward movement of the first filter frame, it will drive the slider along the outer wall of the limit rod. The cam moves downward and stretches the spring. When the cam rotates upward, the spring contracts under the reaction force, causing the slider and the first filter frame to return to their original position. This causes the first filter frame to vibrate, which in turn vibrates the raw materials inside the first filter frame, preventing the raw materials from accumulating inside the first filter frame and affecting the filtration effect of impurities. After the raw materials have been filtered through the first filter frame, they fall into the second filter frame, where they undergo secondary filtration. During the up-and-down vibration of the first filter frame, the hinge causes the support plate to rotate. Combined with the horizontal plate limiting the brush plates, this causes the two brush plates to move along the inner wall of the second filter frame, thereby brushing the raw materials inside the second filter frame and improving the filtration efficiency of the second filter frame for impurities in the raw materials.

[0016] (2) This efficient and convenient activated carbon filtration device, by setting up purification components, can adsorb the odor generated by the odor generated by the filtration of the raw materials of medicine during the filtration process. First, the operator inserts the T-shaped blocks at both ends of the activated carbon adsorption layer into the U-shaped block to assemble the activated carbon adsorption layer. When the raw materials of medicine are filtered inside the treatment box, the odor in the raw materials of medicine will be adsorbed through the activated carbon adsorption layer inside the purification box, thereby improving the treatment effect of the device on the raw materials of medicine.

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] like Figure 1-5 As shown, this utility model has the following two specific embodiments.

[0025] Example 1

[0026] A highly efficient and convenient activated carbon filtration device includes a treatment box 1;

[0027] The material discharge chute 3 is located on the left side of the processing box 1;

[0028] The filter assembly 41 is disposed inside the processing box 1. The filter assembly 41 includes slide grooves 411 formed on the inner walls of both sides of the processing box 1. A drive motor 412 is fixedly connected to the back of the processing box 1. An output shaft 413 is fixedly connected to the output end of the drive motor 412. The output shaft 413 movably passes through the back of the processing box 1 and extends into the interior of the processing box 1. A cam 414 is fixedly connected to the outer wall of the other end of the output shaft 413. A pressing block 415 is slidably connected to the bottom of the cam 414. A first filter frame 416 is fixedly connected to the side wall of the pressing block 415. A slider 417 is fixedly connected to both sides of the first filter frame 416. A limit rod 418 is slidably connected to the inner wall of the slider 417. Both ends of the limit rod 418 are connected to the inner wall of the slide groove 411. A spring 419 is fixedly connected to the top of the slider 417, and the other end of the spring 419 is fixedly connected to the top of the inner wall of the slide groove 411. Two support plates 4110 are movably connected to the center bottom of the first filter frame 416 via two hinges. A brush plate 4111 is movably connected to the other end of the support plate 4110 via a hinge. A horizontal plate 4112 is slidably connected to the top of the brush plate 4111, and a second filter frame 4113 is fixedly connected to the bottom of the horizontal plate 4112. The outer wall of the second filter frame 4113 is fixedly connected to the inner wall of the processing box 1, and the bottom of the brush plate 4111 is slidably connected to the bottom of the inner wall of the second filter frame 4113. By setting the filter assembly 41, impurities in the raw materials of the medicine need to be removed during the production process. Filtration is performed to prevent impurities from mixing with the pharmaceutical raw materials and affecting the production effect of the medicine. During the filtration process, the operator first places the pharmaceutical raw materials inside the first filter frame 416. Impurities in the pharmaceutical raw materials are initially filtered through the first filter frame 416. To prevent the pharmaceutical raw materials from accumulating inside the first filter frame 416 and affecting the filtration efficiency, the operator turns on the drive motor 412, causing the output shaft 413 to rotate. During the rotation of the output shaft 413, the cam 414 rotates. As the cam 414 rotates, its bottom presses against the extrusion block 415, thereby pushing the first filter frame 416 downwards. During the movement, the slider 417 moves downward along the outer wall of the limiting rod 418, stretching the spring 419. When the cam 414 rotates upward, it contracts under the reaction force of the spring 419, causing the slider 417 and the first filter frame 416 to return to their original position. This causes the first filter frame 416 to vibrate, thus vibrating the pharmaceutical raw materials inside the first filter frame 416. This prevents the pharmaceutical raw materials from accumulating inside the first filter frame 416, which would affect the filtration effect on impurities. After the pharmaceutical raw materials have been filtered through the first filter frame 416, they fall into the second filter frame 4113, where they undergo secondary filtration. This process is repeated during the up-and-down vibration of the first filter frame 416.The hinge causes the support plate 4110 to rotate, and with the horizontal plate 4112 limiting the position of the brush plates 4111, the two brush plates 4111 move along the inner wall of the second filter frame 4113. This allows them to brush the pharmaceutical materials inside the second filter frame 4113, thereby improving the filtration efficiency of the second filter frame 4113 for impurities in the pharmaceutical materials.

[0029] The filter assembly 41 also includes an inclined filter plate 4114 fixedly connected to the inner wall of the processing box 1. The inclined filter plate 4114 is located below the second filter frame 4113. A U-shaped frame 4115 is fixedly connected to the left side of the processing box 1. A collection frame 4116 is slidably connected to the bottom of the inner wall of the U-shaped frame 4115. The collection frame 4116 is located at the lower left of the material drop chute 3. After the medicine raw material is filtered through the second filter frame 4113, it will fall onto the surface of the inclined filter plate 4114. Under the guiding action of the inclined filter plate 4114, the medicine raw material will be filtered again along the surface of the inclined filter plate 4114 and fall into the inside of the collection frame 4116 after filtration. The collection frame 4116 collects the medicine raw material, thereby realizing the entire filtration process and improving the filtration effect of the medicine raw material.

[0030] The bottom of the processing box 1 is fixedly connected with four support legs 2. The four support legs 2 are fixedly connected at equal intervals at the bottom of the four corners of the processing box 1. The four support legs 2 at the bottom of the processing box 1 can provide stable support for the processing box 1.

[0031] The front of the processing box 1 is hinged to a door 5. An observation window 6 is fixedly connected to the inner wall of the door 5. A handle 7 is fixedly connected to the front of the door 5. With the door 5 and handle 7 on the front of the processing box 1, after the raw materials of the medicine are filtered, the operator can open the door 5 by pulling the handle 7, so as to clean the impurities that remain inside the first filter frame 416 and the second filter frame 4113 after filtration. With the observation window 6 inside the door 5, the operator can observe the filtration of the raw materials of the medicine inside the processing box 1 from the outside through the observation window 6 during the filtration process.

[0032] There are two brush plates 4111, and the two brush plates 4111 are symmetrically distributed along the central face of the second filter frame 4113.

[0033] Example 2

[0034] The difference from Embodiment 1 is that this embodiment discloses a purification component, such as... Figure 5 As shown:

[0035] The processing box 1 is also equipped with a purification component 42. The purification component 42 includes a purification box 421 fixedly connected to the top of the inner wall of the processing box 1. A U-shaped block 423 is fixedly connected to the inner wall of the purification box 421. A T-shaped block 424 is slidably connected to the inner side wall of the U-shaped block 423. An activated carbon adsorption layer 425 is fixedly connected to the side wall of the T-shaped block 424. Multiple through slots 422 are opened at the bottom of the purification box 421. By setting up the purification component 42, during the filtration of pharmaceutical raw materials, since the pharmaceutical raw materials may contain some irritating odors, in order to... To effectively remove odors generated during the filtration of pharmaceutical raw materials, the activated carbon adsorption layer 425 is used to adsorb the odors. First, the operator inserts the T-shaped blocks 424 at both ends of the activated carbon adsorption layer 425 into the interior of the U-shaped blocks 423, thereby assembling the activated carbon adsorption layer 425. When the pharmaceutical raw materials are being filtered inside the treatment box 1, the activated carbon adsorption layer 425 inside the purification box 421 adsorbs the odors in the pharmaceutical raw materials, thereby improving the treatment effect of the device on the pharmaceutical raw materials.

[0036] Working Principle: In the pharmaceutical production process, it is necessary to filter impurities in the raw materials to prevent them from mixing with the raw materials and affecting the production effect. During the filtration process, the operator first places the raw materials inside the first filter frame 416 for initial filtration of impurities. To prevent the raw materials from accumulating inside the first filter frame 416 and affecting the filtration efficiency, the operator turns on the drive motor 412, causing the output shaft 413 to rotate. During the rotation of the output shaft 413, the cam 414 rotates. As the cam 414 rotates, its bottom presses against the extrusion block 415, pushing the first filter frame 416 downwards. As the first filter frame 416 moves downwards, it causes the slider 417 to move downwards along the outer wall of the limit rod 418, stretching the spring 419. When the cam 414 rotates upwards... Under the reaction force of the spring 419, the slide block 417 and the first filter frame 416 will retract and drive the slide block 417 and the first filter frame 416 to return to their original position. This causes the first filter frame 416 to vibrate, which in turn vibrates the raw materials inside the first filter frame 416, preventing the raw materials from accumulating inside the first filter frame 416 and affecting the filtration effect of impurities. After the raw materials are filtered through the first filter frame 416, they will fall into the second filter frame 4113. The second filter frame 4113 can perform secondary filtration on the raw materials. When the first filter frame 416 vibrates up and down, the hinge will cause the support plate 4110 to rotate. After the horizontal plate 4112 limits the brush plate 4111, the two brush plates 4111 will move along the inner wall of the second filter frame 4113, thereby brushing the raw materials inside the second filter frame 4113 and improving the filtration efficiency of the second filter frame 4113 for impurities in the raw materials.

[0037] After the drug material has been filtered through the second filter frame 4113, it will fall onto the surface of the inclined filter plate 4114. Under the guiding effect of the inclined filter plate 4114, the drug material will be filtered again along the surface of the inclined filter plate 4114 and fall into the collection frame 4116 after filtration. The collection frame 4116 collects the drug material, thereby completing the entire filtration process and improving the filtration effect of the drug material.

[0038] During the filtration of pharmaceutical raw materials, some irritating odors may be present. To effectively remove these odors during filtration, an activated carbon adsorption layer 425 is used to adsorb them. First, the operator inserts the T-shaped blocks 424 at both ends of the activated carbon adsorption layer 425 into the U-shaped blocks 423, thus assembling the activated carbon adsorption layer 425. When the pharmaceutical raw materials are being filtered inside the treatment chamber 1, the odors in the pharmaceutical raw materials are adsorbed through the activated carbon adsorption layer 425 inside the purification chamber 421, thereby improving the treatment effect of the device on the pharmaceutical raw materials.

[0039] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this application.
