Description

Technical Field

[0001] The invention relates to the technical field of material storage equipment, and in particular to a closed raw material storage equipment for acetaminophen production. Background Art

[0002] Acetaminophen is an organic compound that mainly inhibits the activity of cyclooxygenase (COX) in arachidonic acid metabolism and reduces prostaglandin synthesis. Unlike nonsteroidal anti-inflammatory drugs such as aspirin, acetaminophen is not very selective for COX-1 and COX-2, but mainly acts in the central nervous system and has relatively weak peripheral effects, so its anti-inflammatory effect is not obvious. Long-term contact may cause skin allergies and other problems. The raw materials need to be stored in a cool and ventilated warehouse. When storing the raw materials, the staff needs to wear protective glasses, gloves, etc. to avoid dust during operation and prevent inhalation and skin contact.

[0003] The raw materials of acetaminophen are stored in storage tanks, which are placed in dry and well-ventilated warehouses and equipped with exhaust fans and dehumidification equipment to reduce humidity. At the same time, the warehouse temperature should be kept stable to avoid condensation caused by drastic temperature changes. An appropriate amount of desiccant, such as silica gel and montmorillonite, is placed in the package to absorb moisture in the package and keep the raw materials dry. Pay attention to regularly check the status of the desiccant and replace the expired desiccant in time.

[0004] The acetaminophen raw material in the storage tank is protected from moisture by desiccant. Different humidity levels will result in different moisture rates for the raw material. Regular inspections of the desiccant status may result in untimely replacement of the desiccant.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Example 1

[0037] This embodiment provides a closed raw material storage device for acetaminophen production, such as Figure 1 and Figure 2 As shown, it includes a sealed can 1, a feed pipe 2 is fixedly installed on the top of the sealed can 1, and symmetrically arranged hook blocks are fixedly installed on the side of the sealed can 1, and the hook blocks are used to hang hooks to transport the sealed can 1.

[0038] like Figures 2 to 4 As shown, a dry conversion assembly 3 is provided at the top of the feed pipe 2, and the dry conversion assembly 3 includes a sealing cover 31, a protection frame 32, an activated carbon drying bag 33, a support spring 34, a ladder block 35, a dislocation assembly and a strong magnet 38. The interior of the sealing cover 31 is slidably connected to the protection frame 32 up and down, and the inner wall of the protection frame 32 is slidably connected to the activated carbon drying bag 33. The top of the activated carbon drying bag 33 is elastically connected to the activated carbon drying bag 33 and the support spring 34 is elastically connected. The protection frame 32 extends into the interior of the sealed tank 1, and absorbs moisture inside the sealed tank 1 through the activated carbon drying bag 33. As the moisture is absorbed, the weight of the activated carbon drying bag 33 increases, and the activated carbon drying bag 33 is used to pull down the support spring 34 to move.

[0039] The top of the activated carbon drying bag 33 is fixedly connected to the ladder block 35 through a straight rod, and a strong magnet 38 is fixedly installed on the top of the protection frame 32. The dislocation component is arranged above the strong magnet 38, and the dislocation component includes a shielding slider 36 and a dislocation opening 37. The dislocation opening 37 is provided in the middle of the shielding slider 36, and a slope is provided on the side of the shielding slider 36 facing the ladder block 35. The ladder block 35 is embedded in the slope of the shielding slider 36. Initially, the dislocation opening 37 is dislocated with the strong magnet 38.

[0040] like Figure 4 As shown, the activated carbon drying bag 33 utilizes the ladder block 35 to squeeze the shielding slider 36, thereby moving the shielding slider 36 so that the strong magnet 38 is aligned with the offset opening 37. At this time, the strong magnet 38 leaks out from the shielding of the shielding slider 36. Since the ladder block 35 is embedded in the inclined surface of the shielding slider 36, when the ladder block 35 moves upward or downward, the shielding slider 36 always moves with the ladder block 35.

[0041] like Figure 2 As shown, the separation gas storage plate 310 is made of one of iron sheet, cobalt sheet or nickel sheet, and a sealing rubber is fixedly installed at the position where the separation gas storage plate 310 contacts the sealing cover 31. A limiting iron frame 311 is fixedly installed on the top of the sealing cover 31, and a vent is provided on the side of the limiting iron frame 311. Due to the magnetic force of the strong magnet 38, the strong magnet 38 attracts the separation gas storage plate 310. Since the strong magnet 38 is located at the top center of the protection frame 32, when the separation gas storage plate 310 is tilted, the strong magnet 38 cannot contact the separation gas storage plate 310, so the strong magnet 38 drives the protection frame 32 to move upward.

[0042] A butt plate 39 is fixedly installed on the top of the protection frame 32 . The butt plate 39 is close to the rotating shaft connecting the protection frame 32 and the partitioning and air storage plates 310 . Two partitioning and air storage plates 310 are provided. The height of the butt plate 39 is higher than that of the protection frame 32 . During the upward movement of the protection frame 32, the push plate 39 preferentially contacts the partition air storage plate 310. Since the push plate 39 is close to the rotating shaft connecting the protection frame 32 and the partition air storage plate 310, the push plate 39 causes the partition air storage plate 310 to flip. After the partition air storage plate 310 located at the bottom is flipped, the partition air storage plate 310 located at the top is exposed to the moving path of the strong magnet 38. The magnetic force of the strong magnet 38 continues to act, and the protection frame 32 moves toward the partition air storage plate 310 located at the top. The above steps are repeated, and finally the protection frame 32 and the activated carbon drying bag 33 move to the limiting iron frame 311, and the protection frame 32 moves to the outside of the sealed can 1. An exhaust fan and a dehumidification device are usually arranged in the warehouse for storing the sealed can 1 to accelerate the drying of the protection frame 32.

[0043] A support magnet 312 is fixedly installed on the top of the activated carbon drying bag 33, and a disc is fixedly installed below the top wall of the activated carbon drying bag 33. The magnetic force of the support magnet 312 is smaller than the gravity of the activated carbon drying bag 33. When the activated carbon drying bag 33 is wetted and its gravity is greater than the magnetic force of the support magnet 312 and the elastic force of the support spring 34, the activated carbon drying bag 33 moves downward to prevent the support spring 34 from being continuously affected by the gravity of the activated carbon drying bag 33.

[0044] In this embodiment, after the activated carbon drying bag 33 absorbs moisture, its gravity increases, thereby causing the dislocation component to be dislocated with the strong magnet 38, and the magnetic force of the strong magnet 38 causes the protection frame 32 to move upward, and finally the strong magnet 38 is adsorbed on the limiting iron frame 311. The warehouse where the sealed can 1 is stored is usually equipped with an exhaust fan and a dehumidification device to accelerate the drying of the protection frame 32, so that after the activated carbon drying bag 33 absorbs the set moisture, it automatically pops up and dries, and the process is carried out in time to avoid excessive moisture in the sealed can 1.

[0045] Example 2

[0046] Based on Example 1, this example proposes a closed raw material storage device for acetaminophen production, such as Figure 5 As shown, the sealing cover 31 is provided with a gas recovery assembly 4 inside, and the gas recovery assembly 4 includes a central dial plate 41, a docking shaft 42, a coil spring 43, a transfer assembly, an adjustment shaft 45, a docking plate 47 and a buffer airbag 49. The docking shaft 42 is fixedly installed on the arc surface of the central dial plate 41, and the docking shaft 42 is rotatably connected to the sealing cover 31. The coil spring 43 elastically connects the sealing cover 31 and the docking shaft 42. The end of the docking shaft 42 is provided with a transfer assembly, and the top of the transfer assembly is rotatably connected to the adjustment shaft 45. The docking plate 47 slides up and down at the rod of the adjustment shaft 45, and the bottom of the docking plate 47 is fixedly installed with a buffer airbag 49. The inner wall of the sealing cover 31 is located between the two partition gas storage plates 310 and is rotatably connected to the central dial plate 41. The material of the central dial plate 41 is the same as that of the partition gas storage plate 310.

[0047] like Figure 6 As shown, during the upward movement of the protection frame 32, the protection frame 32 uses the abutment plate 39 to squeeze the middle dial plate 41 to make it flip over, so that the middle dial plate 41 and the docking shaft 42 squeeze the coil spring 43, and the docking shaft 42 drives the adjustment shaft 45 to rotate using the conversion assembly. The adjustment shaft 45 is provided with a slide rail 46, and the slide rail 46 adopts a spiral structure. The inner wall of the docking plate 47 is rollingly connected with a slide ball 48, and the slide ball 48 rolls in the slide rail 46.

[0048] The adjusting shaft 45 rotates clockwise and utilizes the slide rail 46 to move the sliding ball 48 along the slide rail 46, thereby achieving the effect of moving the docking plate 47 upward. The docking plate 47 moves upward to pull the cache air bag 49 to make it inhale. After the protection frame 32 is adsorbed on the limiting iron frame 311, the elastic force of the coil spring 43 resets the center dial plate 41, so that the adjusting shaft 45 rotates counterclockwise, so that the docking plate 47 moves downward to squeeze the cache air bag 49 for exhaust.

[0049] The two ends of the buffer air bag 49 are connected with hoses, one end of one hose is fixedly installed with a one-way suction pipe 410 that can only inhale, and the other end of the hose is fixedly installed with a valve that can only discharge. The one-way suction pipe 410 is located between the two partition gas storage plates 310. The gas entering between the two partition gas storage plates 310 is absorbed by the buffer air bag 49 to prevent the gas emitted by the volatile raw materials from being discharged from the sealed tank 1; and when the middle dial plate 41 is reset, the buffer air bag 49 discharges gas and discharges the internal gas into the sealed tank 1.

[0050] The adapter assembly includes a bevel gear set 44 and an intermediate block. The ends of the docking shaft 42 and the adjusting shaft 45 are rotatably connected to the intermediate block. The bevel gear set 44 includes two mutually perpendicular and meshing bevel gears, which are fixedly mounted on the ends of the docking shaft 42 and the adjusting shaft 45 respectively.

[0051] Two partitioning air storage plates 310 are provided, and the inner wall of the sealing cover 31 is located between the two partitioning air storage plates 310 and is rotatably connected to the middle dial plate 41. The material of the middle dial plate 41 is the same as that of the partitioning air storage plate 310. Both ends of the cache air bag 49 are respectively connected with hoses, and one end of one of the hoses is fixedly installed with a one-way air intake pipe 410 that can only inhale, and the other end of the hose is fixedly installed with a valve that can only exhaust. The one-way air intake pipe 410 is located between the two partitioning air storage plates 310.

[0052] After the activated carbon drying bag 33 is dried, the activated carbon drying bag 33 is pulled back to its original position by the supporting spring 34 and the supporting magnet 312 , so that the shielding slider 36 shields the strong magnet 38 and the limiting iron frame 311 , and the protection frame 32 moves downward under the action of gravity and moves into the sealing can 1 again.

[0053] In this embodiment, the intake and exhaust of the buffer airbag 49 are achieved by flipping and resetting the middle dial plate 41. Since the one-way intake pipe 410 can only inhale air, the gas emitted by the raw material entering between the two partition gas storage plates 310 is absorbed by the buffer airbag 49 to prevent the irritating gas from being discharged from the sealed tank 1, and the gas is discharged into the sealed tank 1 after the middle dial plate 41 is reset.

[0054] Example 3

[0055] Based on the above-mentioned embodiment 1 or embodiment 2, this embodiment proposes a closed raw material storage device for acetaminophen production, such as Figure 5 , Figure 7 and Figure 8 As shown, a sealing assembly 5 is provided on the outside of the sealing cover 31, and the sealing assembly 5 includes a rubber sealing ring 51, a sealing airbag 52 and a transfer hose 53. The buffer airbag 49 is connected to the transfer hose 53 through a hose, and the end of the transfer hose 53 is connected to the sealing airbag 52. The sealing airbag 52 adopts an annular structure, and the sealing airbag 52 is fixedly installed on the outer arc surface of the sealing cover 31. The rubber sealing ring 51 is fixedly installed on the bottom of the sealing cover 31. The rubber sealing ring 51 and the sealing airbag 52 are cocentric, and the rubber sealing ring 51 and the sealing airbag 52 clamp the feed pipe 2.

[0056] When the gas is squeezed out of the buffer airbag 49, part of the gas enters the sealing airbag 52 through the adapter hose 53, thereby replenishing the gas inside the sealing airbag 52. Since the buffer airbag 49 inevitably has the problem of air leakage, the activated carbon drying bag 33 switches between the wet and dry states, so that the protective frame 32 reciprocates up and down, and the docking plate 47 reciprocates up and down to squeeze and pull the buffer airbag 49, thereby replenishing the gas inside the sealing airbag 52 in time.

[0057] In this embodiment, the rubber sealing ring 51 and the sealing airbag 52 are used to clamp the feed pipe 2, and the sealing cover 31 and the feed pipe 2 are sealed to prevent the irritating gas formed by the acetaminophen raw material from being emitted, and the buffer airbag 49 is deflated to timely replenish the internal gas of the sealing airbag 52 to improve the sealing effect.

[0058] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
