Description

Technical Field

[0001] The invention relates to a storage device, in particular to a pharmaceutical intermediate storage device. Background Art

[0002] Pharmaceutical intermediates refer to chemical raw materials used in the production of drugs. These chemical raw materials are usually toxic to a certain extent, and some require storage conditions such as sealing, light protection, and constant temperature. Otherwise, they are prone to decomposition, denaturation, or even flash explosion, resulting in errors in the proportions of drug production.

[0003] The existing technology usually uses stainless steel sealed tanks to store various pharmaceutical intermediates, which can not only avoid corrosion and have a light-proof effect, but also facilitate the control of environmental temperature and humidity. However, this stainless steel tank has defects in the use of some liquid materials that are easy to precipitate. A stirring structure needs to be installed inside the tank, which has limited stirring effect and reduces the actual space of the storage tank. In addition, the driving energy of the stirring equipment has safety hazards.

[0004] On the other hand, with the input and output of materials, the air inside and outside the storage tank will inevitably interact, and the air entering the storage tank will affect the constant temperature, humidity and low oxygen storage environment inside the tank.

[0005] In response to the above problems, technical personnel in this field have proposed a pharmaceutical intermediate storage device that is designed to meet the storage conditions of pharmaceutical intermediates, can safely stir the materials to prevent sedimentation, and can conveniently control the interaction between internal and external air that affects the storage environment. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a pharmaceutical intermediate storage device. By setting up an inner and outer double-layer tank structure, not only can the storage tank be rotated for installation, but also some liquid materials that are easy to precipitate can be prevented from failing by rotation when stored. In addition, the double-layer tank body provides dry, low-oxygen gas for the storage tank when the material in the storage tank is extracted, and will not interact with the external air to cause the problem of humid air affecting the material storage environment.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a pharmaceutical intermediate storage device, including a storage tank and a cover plate, one end of the storage tank is threadedly provided with a cover plate, and the side of the cover plate is provided with an operating port with a smaller diameter, through which the material is operated to enter and exit, and the threaded cover plate is opened when cleaning is required, and the cover plate is sealed with hot melt adhesive when in use.

[0008] The storage tank is externally sleeved with an outer tank body, and the storage tank is rotatably installed in the outer tank body. When storing liquid materials that are prone to sedimentation and failure, the storage tank rotatably installed in the outer tank body can stir the internal materials through continuous rotation without worrying about safety hazards in installing the driving equipment and occupying a large amount of mass and space.

[0009] A temperature control plate is fixed on the outside of the outer tank body, and the temperature control plate controls the temperature of the air entering the space between the storage tank and the outer tank body. The air entering the outer tank body interacts with the storage tank after the temperature is controlled by the temperature control plate, thereby avoiding a large amount of external high-temperature air from rushing in and causing a drastic change in the storage environment in the storage tank.

[0010] A medicine drawer is inserted into the side of the outer tank body, and dehumidification medicine and reducing medicine are stored in the medicine drawer, which can greatly reduce the content of oxygen and water vapor in the air. The medicine drawer dehumidifies and deoxygenates the air to avoid the interaction between a large amount of oxygen and water vapor and the storage tank, causing deterioration of the storage environment.

[0011] Preferably, the inner wall of the outer tank body is fixedly connected to a support frame corresponding to the storage tank, a driving shaft is penetrated through the side wall of the outer tank body, the driving shaft is connected to a power mechanism, and the storage tank is arranged on the inner side of the support frame and is driven and rotated by the driving shaft.

[0012] The power mechanism is arranged outside the outer tank body, and there is no possibility of leakage or the like affecting the stored materials. The drive shaft is arranged to pass through the outer tank body, causing the loss of the sealing performance of the outer tank body, but the slight loss and the fact that the medicine drawer used for air treatment does not directly act will ultimately not affect the quality of the air entering the storage tank.

[0013] Preferably, a mounting bearing is fixedly connected to the side of the storage tank, and the storage tank is fixedly set on the inner side of the support frame through the mounting bearing. The drive shaft extends to the side of one end of the support frame and is sleeved with a drive gear. The side of the storage tank is fixedly connected with a gear ring corresponding to the drive gear. The drive shaft drives the storage tank to rotate at a uniform speed through meshing, thereby continuously stirring the stored material, which is more effective than installing a general stirring structure and can prevent the problem of liquid material failure due to precipitation of components.

[0014] Preferably, an air intake pipe is provided through the side of the outer tank body, and the air intake pipe is connected to a throttle valve. The throttle valve controls the opening and closing of the air intake pipe through an electronic control device to replenish air to the outer tank body. External air enters the outer tank body through the throttle valve and the air intake pipe. When the material inside the storage tank is extracted, the gas in the outer tank body is replenished into the storage tank, and the external air then enters the outer tank body for replenishment, so as to avoid the air pressure change affecting the extraction of the material. The throttle valve can prevent a large amount of water vapor from entering from the outside.

[0015] Preferably, an installation box is fixedly connected to the side of the outer tank body, and the temperature control panel is fixedly arranged on the side of the outer tank body through the installation box. Interaction holes are arranged through the side of the outer tank body and at the installation position of the installation box, and a fireproof layer is arranged on the inner side of the installation box.

[0016] The temperature control plate is arranged by arranging a mounting box on the side of the outer tank body to avoid the temperature control structure being close to the storage tank and directly affecting the storage environment of the storage tank, thereby ensuring that the storage tank provides a stable storage environment for the material.

[0017] Preferably, an air duct is fixedly connected to the inner wall of the outer tank body corresponding to the operating port of the storage tank, the medicine drawer passes through the side wall of the outer tank body and extends to the inside of the air duct, an operating push plate is slidably provided on the side of the air duct extending to one end of the operating port of the storage tank, and a positioning hook is hingedly provided on the side of the carry-in end of the operating push plate.

[0018] By arranging an air duct for gas exchange in the outer tank body, not only the problem of the exposed installation of the medicine drawer being difficult to control and use is solved, but also the problem of poor sealing of the outer tank body is avoided. The air duct extends to the operating port of the storage tank. When the material in the storage tank is discharged to the outside, the unsealed air duct inhales the temperature-controlled air in the outer tank body. During the inhalation process, it is ensured that all air passes through the dehumidification and deoxygenation of the medicine drawer to ensure that the gas will not affect the storage environment in the storage tank.

[0019] In addition, an operating push plate is slidably provided at one end of the air duct extending to the operating port of the storage tank to facilitate the input and output operations of materials in the storage tank. The operating push plate is tightly positioned by a positioning hook on the side to help seal the end of the air duct at the operating push plate.

[0020] Preferably, a first spring is fixedly provided on the inner side of the operating push plate, a sealing rubber pad is provided on the end of the first spring, and a fixing block is fixedly connected to the side of the air guide tube corresponding to the positioning hook.

[0021] A sealing rubber pad is arranged by the first spring. As the operating push plate moves forward, the sealing rubber pad is pressed against the side of the conveying pipe and is pressed tightly by the elastic force of the first spring, thereby ensuring a sealing effect on the passage of the conveying pipe.

[0022] After the operating push rod is pushed to the closed position, it is positioned by the positioning hook and the fixing block to ensure the first spring's tightness against the sealing gasket, while preventing the elastic force of the first spring from causing the operating push plate to move and causing loss of air tightness of the equipment.

[0023] Preferably, baffles are slidably provided on the sides of the air duct and on both sides of the medicine drawer. The baffles are provided on both sides to protect the medicines in the medicine drawer, thereby preventing the problem of the medicines being easily ineffective due to being exposed to the air all the time. The baffles will only be opened to dehumidify and deoxygenate the air when the material in the storage tank is being extracted.

[0024] One end of the two baffles passing through the side wall of the air duct is fixedly connected to a connecting plate, and a traction rope is connected to the side of the connecting plate. The traction rope extends to the operating port of the storage tank away from one end of the connecting plate. The movement of the baffle is controlled by the traction rope extended to the operating port of the storage tank. When operating the materials in the storage tank, the baffle is moved to expose the air duct. As the materials in the storage tank are extracted, the internal air pressure decreases, and the air in the outer tank body for temperature control is sucked in through the air duct.

[0025] Preferably, a second spring is provided between the baffle and the inner wall of the air duct, and the second spring helps to reset the baffle, thereby avoiding the problem that the medicine drawer cannot be closed in an open state, causing the medicine to become ineffective.

[0026] A guide pulley is fixed on the side of the storage tank corresponding to the traction rope, and the traction rope is helped to pull the baffle to move through the action of the guide pulley.

[0027] Preferably, a carry-in bar is inserted into the side of the medicine drawer, and the carry-in bar is used to press against the gap between the medicine drawer and the baffle to seal the medicine, which is beneficial to the preservation of the medicine.

[0028] A mounting groove is provided on the side of the medicine drawer, and a sealing strip is arranged on the side of the medicine drawer. The sealing strip is arranged on the side of the medicine drawer through the mounting groove, and a plastic soft board is arranged between the advancing strip and the sealing strip.

[0029] As the baffle moves and squeezes, the advancing strip is squeezed and advances, and the sealing strip is pushed out of the installation groove by the pre-supported plastic soft plate, and is pressed against the side of the baffle for sealing. After the baffle leaves the protective position for the medicine drawer, the advancing strip loses the squeezing effect of the baffle, and the sealing strip is pulled back under the restoring force of the plastic soft plate, so as to avoid friction with the baffle to damage the sealing strip.

[0030] The present invention discloses a pharmaceutical intermediate storage device, which has the following beneficial effects:

[0031] 1. The pharmaceutical intermediate storage equipment sets the material storage tank as an inner and outer two-layer structure. On the one hand, the internal storage tank can be rotated and installed, which can be better used for storing and using liquid materials whose components are easy to precipitate and cause failure. Compared with the equipment with an internal stirring structure, there is no safety hazard of leakage and it will not occupy the storage space. On the other hand, the equipment pre-treats the air through the gap between the inner and outer two-layer structures, and the air interacts with the storage tank through this part of the air. When the material in the storage tank is drawn out to form a negative pressure, it is replenished. This part of the air is temperature controlled, and the medicine in the medicine drawer is dehumidified and deoxygenated, which will not cause an imbalance in the storage environment inside the storage tank.

[0032] 2. The storage tank with double-layer structure inside and outside of the pharmaceutical intermediate storage equipment will not increase the overall mass of the equipment too much. It only needs to reserve a certain space to accommodate a certain amount of air, which is convenient for the safe interaction when the material in the storage tank needs to be supplemented with air when it is output to the outside. In addition, the dynamic storage environment of the storage tank is also realized, which has a better storage effect for some liquid materials whose components are easy to precipitate. The temperature of part of the air entering the outer tank body is adjusted by the temperature control board, and the water vapor and oxygen in the air are absorbed during the interaction to prevent water vapor and oxygen from entering the storage tank and causing the failure of the stored materials.

[0033] 3. The pharmaceutical intermediate storage equipment installs the temperature control board by fixing the installation box on the side of the outer tank body, and opens interactive holes on the side wall of the outer tank body, and installs a fireproof layer to prevent the distance between the temperature control board and the storage tank from being too small to affect the storage temperature of the storage tank.

[0034] 4. The pharmaceutical intermediate storage equipment has a baffle installed on the side of the air duct to protect the medicine in the medicine drawer, so as to avoid the problem that the medicine is easily ineffective due to the poor airtightness of the outer tank body. In addition, a movable sealing strip is provided on the side of the medicine drawer to ensure the sealing effect. With the setting of the baffle, the hollow advance strip with good elasticity is squeezed and deformed, and while accumulating elastic potential energy, a thrust is applied to the plastic soft plate to push the sealing strip out of the receiving groove and press against the side of the baffle. After the baffle leaves, the advance strip is reset, driving the sealing strip to retract into the receiving groove, so as to avoid the sealing strip extending out of the receiving groove hindering the advance of the baffle, so that the medicine in the medicine drawer can be controlled to be opened or closed according to the need of air interaction in the storage tank.

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The embodiment of the present invention discloses a pharmaceutical intermediate storage device;

[0047] According to the attached Figure 1 and attached Figure 2As shown, it includes a storage tank 1 and a cover plate 2. The cover plate 2 is threadedly provided at one end of the storage tank 1. The one end of the storage tank 1 is sealed by the threaded cover plate 2. An operating port for material transportation is provided on the side of the cover plate 2. The threaded cover plate 2 structure is convenient for disassembly and cleaning of the storage tank 1. After the cover plate 2 is tightened, it is sealed with a sealing sol.

[0048] The storage tank 1 is externally sleeved with an outer tank body 3, and the storage tank 1 is rotatably installed in the outer tank body 3. The rotatable storage tank 1 can realize safe storage of easily precipitated materials, avoid the safety hazard of leakage caused by installing a stirring device in the storage tank 1 in the prior art, and avoid the problem of the internally installed stirring device occupying the capacity of the storage tank 1.

[0049] A temperature control plate 4 is fixed to the outside of the outer tank body 3 , and the temperature of the air entering the outer tank body 3 is controlled by the temperature control plate 4 to prevent this part of the air from directly interacting with the storage tank 1 and affecting the storage environment of the storage tank 1 on a large scale.

[0050] A medicine drawer 5 is inserted into the side of the outer tank body 3. The medicine drawer 5 contains a moisture-absorbing medicine and a substance that reacts with oxygen in the air to reduce the oxygen content in the air. The air inside the outer tank body 3 is treated to prevent the air from entering the storage tank 1 and causing the medicine to become damp and oxidized and become ineffective.

[0051] According to the attached Figure 2 As shown, an air intake pipe 11 is provided through the side of the outer tank body 3 , and the air intake pipe 11 is connected to a throttle valve 12 . The throttle valve 12 controls the on-off of the air intake pipe 11 through an electronic control device to replenish air to the outer tank body 3 .

[0052] According to the attached Figure 3 As shown, the inner wall of the outer tank body 3 is fixedly connected to a support frame 6 corresponding to the storage tank 1, a driving shaft 7 is penetrated through the side wall of the outer tank body 3, the driving shaft 7 is connected to a power mechanism, and the storage tank 1 is driven and rotated by the driving shaft 7 and is arranged on the inner side of the support frame 6. The driving shaft 7 penetrates the outer tank body 3 and will not hinder the treatment of the interactive air by the device.

[0053] On the one hand, part of the air in the outer tank body 3 does not directly interact with the storage tank 1 , and on the other hand, the medicine drawer 5 is also provided with other protective structures, which will only play a role when the material in the storage tank 1 needs to be supplemented with air when it is extracted.

[0054] A mounting bearing 8 is fixedly connected to the side of the storage tank 1, and the storage tank 1 is fixedly set on the inner side of the support frame 6 through the mounting bearing 8. The driving shaft 7 extends to the side of one end of the support frame 6 and is sleeved with a driving gear 9. A gear ring 10 is fixedly connected to the side of the storage tank 1 corresponding to the driving gear 9. The storage tank 1 can rotate in the outer tank body 3 under the action of the mounting bearing 8. The power is provided by the driving shaft 7, and the driving gear 9 engages to drive the outer tank body 3 to rotate at a uniform speed.

[0055] The side of the outer tank body 3 is fixedly connected with an installation box 13, and the temperature control board 4 is fixedly set on the side of the outer tank body 3 through the installation box 13. Interaction holes are set through the side of the outer tank body 3 and at the installation position of the installation box 13, and a fireproof layer is set on the inner side of the installation box 13.

[0056] The temperature control panel 4 is arranged on the outside of the outer tank body 3 by means of an installation box 13 , and is provided with a fireproof layer and interactive holes to prevent the storage temperature of the storage tank 1 from being affected by close-range equipment.

[0057] According to the attached Figure 4 As shown, an air duct 14 is fixedly connected to the inner wall of the outer tank body 3 corresponding to the operation port of the storage tank 1, and the medicine drawer 5 passes through the side wall of the outer tank body 3 and extends to the inside of the air duct 14. There is a part of air in the outer tank body 3 that has been temperature-controlled by the temperature control plate 4. When air needs to be supplemented in the storage tank 1, the output port of the storage tank 1 and the inside of the outer tank body 3 are directly connected through the air duct 14, and the temperature-treated air is sucked into the air duct 14, and the water vapor and oxygen in this part of the air are absorbed.

[0058] An operating push plate 15 is slidably provided on the side of the air guide tube 14 extending to one end of the operating port of the storage tank 1, and a positioning hook 16 is hingedly provided on the side of the carrying end of the operating push plate 15. The operating push plate 15 provides an opening for connecting the outside world with the operating port of the storage tank 1, and the operating push plate 15 is positioned with the help of the positioning hook 16.

[0059] According to the attached Figure 5 As shown, a first spring 17 is fixedly provided on the inner side of the operating push plate 15, and a sealing rubber pad 18 is provided on the end of the first spring 17. The sealing rubber pad 18 provided by the first spring 17 presses against the side of the material conveying pipe as the operating push plate 15 moves. The gap is reduced under the elastic force of the first spring 17, and combined with the open supply air duct 14, the direct interaction between the storage tank 1 and the outside air is reduced.

[0060] A fixing block 19 is fixedly connected to the side of the air guide tube 14 corresponding to the positioning hook 16. When the operating push plate 15 is pushed against the material conveying pipe, the first spring 17 is squeezed. The elastic force exerts a thrust on the operating push plate 15. The positioning hook 16 and the fixing block 19 are combined to resist the thrust, thereby ensuring the airtight effect at the end of the air guide tube 14.

[0061] According to the attached Figure 6 and attached Figure 7 As shown, baffles 20 are slidably arranged on the sides of the air duct 14 and on both sides of the medicine drawer 5. The baffles 20 arranged on both sides are used to seal and preserve the medicines in the medicine drawer 5, thereby preventing the problem of the medicines becoming ineffective due to long-term exposure to containers with poor airtightness.

[0062] One end of the two baffles 20 that pass through the side wall of the air duct 14 is fixedly connected to a connecting plate 21, and a traction rope 22 is connected to the side of the connecting plate 21. The traction rope 22 extends to the operating port of the storage tank 1 away from the end of the connecting plate 21, so as to facilitate direct operation of the baffle 20 from the operating port of the storage tank 1.

[0063] A second spring 23 is arranged between the baffle 20 and the inner wall of the air duct 14. After the traction rope 22 is loosened under the action of the second spring 23, the baffle 20 restores the sealing protection of the medicine drawer 5. A guide pulley 24 is fixed to the side of the storage tank 1 corresponding to the traction rope 22. The guide pulley 24 is arranged to change the traction direction of the traction rope 22, so as to facilitate the control of the baffle 20 by the end of the storage tank 1.

[0064] According to the attached Figure 8 As shown, a carry-in strip 25 is inserted into the side of the medicine drawer 5, a mounting groove is opened on the side of the medicine drawer 5, a sealing strip 26 is arranged on the side of the medicine drawer 5, the sealing strip 26 is arranged on the side of the medicine drawer 5 through the mounting groove, and a plastic soft board 27 is arranged between the carry-in strip 25 and the sealing strip 26.

[0065] The carry-in bar 25 is made of plastic with good elasticity and is set to a hollow structure. When squeezed, the carry-in bar 25 is deformed and squeezed toward the inside of the medicine drawer 5, pushing the plastic soft board 27 and the sealing strip 26 fixed to the plastic soft board 27. After the baffle 20 leaves, the carry-in bar 25 recovers under the action of elastic potential energy, pulling the plastic soft board 27 and the sealing strip 26 fixed to the plastic soft board 27 into the groove on the side of the medicine drawer 5, preventing the sealing strip 26 from extending out and hindering the movement of the baffle 20.

[0066] The pharmaceutical intermediate storage device sets the material storage tank as an inner and outer two-layer structure. On the one hand, the internal storage tank 1 can be rotatably installed, and can be better used for storing and using liquid materials whose components are easily precipitated and become ineffective. Compared with the equipment with an internal stirring structure, there is no safety hazard of leakage, and it will not occupy the storage space. On the other hand, the device pre-treats the air through the gap between the inner and outer two-layer structures, and this part of air interacts with the storage tank 1, and is replenished when the material in the storage tank 1 is extracted to form a negative pressure. This part of air is temperature controlled, and the medicine in the medicine drawer 5 is dehumidified and deoxygenated, so that the internal storage environment of the storage tank 1 will not be unbalanced.

[0067] Furthermore, the storage tank 1 with an inner and outer double-layer structure will not increase the overall mass of the equipment too much. It only needs to reserve a certain space to accommodate a certain amount of air, which is convenient for the safe interaction when the material in the storage tank 1 needs to be supplemented with air when it is output to the outside. In addition, the dynamic storage environment of the storage tank 1 is also realized, which has a better storage effect for some liquid materials whose components are easy to precipitate. Part of the air entering the outer tank body 3 is adjusted in temperature through the temperature control plate 4, and absorbs water vapor and oxygen in the air during the interaction, so as to prevent water vapor and oxygen from entering the storage tank 1 and causing the failure of the stored materials.

[0068] Furthermore, the temperature control board 4 is installed by fixing the installation box 13 on the side of the outer tank body 3, and an interactive hole is opened on the side wall of the outer tank body 3, and a fireproof layer is installed to prevent the storage temperature of the storage tank 1 from being affected by the small distance between the temperature control board 4 and the storage tank 1.

[0069] Furthermore, a baffle 20 is inserted and arranged on the side of the air duct 14 to protect the medicine in the medicine drawer 5, so as to avoid the problem that the medicine is easily ineffective due to the poor airtightness of the outer tank body 3. In addition, a movable sealing strip 26 is arranged on the side of the medicine drawer 5 to ensure the sealing effect. With the setting of the baffle 20, the hollow advance strip 25 with good elasticity is squeezed and deformed, and while accumulating elastic potential energy, a thrust is exerted on the plastic soft board 27 to push the sealing strip 26 out of the receiving groove and press against the side of the baffle 20. After the baffle 20 leaves, the advance strip 25 is reset, driving the sealing strip 26 to retract into the receiving groove, so as to avoid the sealing strip 26 extending out of the receiving groove hindering the advance of the baffle 20, so that the medicine in the medicine drawer 5 can be controlled to be opened or closed according to the need of air interaction in the storage tank 1.
