Description

Technical Field

[0001] This invention relates to the field of sterilization, and more particularly to a sterilizing autoclave for veterinary drug production. Background Technology

[0002] An autoclave is a device that uses high-temperature, high-pressure steam for sterilization, typically used to disinfect various items in production and daily life. In the preparation and packaging of veterinary drugs, it is usually necessary to sterilize raw materials, intermediate products, and packaging bottles, and most of these sterilization processes are carried out using an autoclave.

[0003] The sterilizers used in the prior art typically consist of a double-layer structure. The upper layer is usually the pot body used to place items, while the lower layer is usually a heater used to generate high-temperature steam. The heater evaporates water at a high temperature to form high-temperature steam. As the gas pressure continuously increases during the heating process, it forms a high-temperature and high-pressure steam sterilization function. Although it can achieve normal sterilization, in veterinary drug production, this type of sterilizer usually requires the operator to repeatedly load and unload materials. Each operation requires avoiding burns to the operator's arms from the high-temperature steam, which is not only inefficient but also poses a safety risk to the user. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides the following technical solution:

[0005] A sterilizer for veterinary drug production includes: a pot body, a first shell and a second shell nested inside the pot body, and a polymer component covering the outside of the pot body.

[0006] Specifically, a lid is detachably mounted on the top of the pot body. The second shell moves up and down linearly along the outer side wall of the first shell. The first shell can move up and down vertically along the center of the pot body. Several retractable receiving hoppers are provided on the outer side wall of the second shell. The end of the receiving hopper away from the second shell can be tilted downward to form a discharge state. The material gathering component is used to receive the material discharged from the receiving hopper.

[0007] As an improvement to the above technical solution, a steam generating mechanism is provided at the lower end of the pot body. The steam generating mechanism includes a bottom cylinder that is detachably fixed to the pot body. An installation groove is provided on one side of the bottom cylinder. A heating element is fixed inside the installation groove. The heating element is located inside the bottom cylinder and is electrically connected to a heating wire.

[0008] As an improvement to the above technical solution, a connecting groove penetrating into the interior of the pot body is provided at the center of the bottom cylinder, and a drive assembly for driving the lifting and lowering of the first and second shells is sealed inside the connecting groove.

[0009] As an improvement to the above technical solution, the drive assembly includes a motor one and a motor two. The motor two is fixed inside the housing one. The power end of the motor two is connected to a lead screw two for driving the housing two to rise and fall. A base frame is fixed to the lower end face of the bottom cylinder. The motor one is fixed to the upper end face of the center position of the base frame. The power end of the motor one is connected to a lead screw one for driving the housing one to rise and fall.

[0010] As an improvement to the above technical solution, a positioning frame is fixed on the upper end face of the first housing, and a base plate is integrally formed on both the upper and lower ends of the second housing. The second lead screw is threaded through the base plate, and a limit groove is opened on the surface of the base plate. The positioning frame is inserted into the interior of the limit groove, and the second housing moves up and down linearly along the positioning frame. The connecting groove at the center of the bottom cylinder is rectangular, and the first housing is inserted into and fits against the inner wall of the connecting groove. The first lead screw is threaded through the bottom of the first housing.

[0011] As an improvement to the above technical solution, at least two vertically arranged positioning grooves are provided on the surface of the second housing. A track component that is detachably fixed to the first housing is horizontally inserted into the inside of the positioning groove. The receiving hopper is located at the upper end of the track component. An adjustment belt is provided on the side of the receiving hopper near the second housing. The other end of the adjustment belt is fixed to the inner wall of the second housing.

[0012] As an improvement to the above technical solution, a connecting plate is integrally formed between two adjacent track components near one end of the housing. A slot is provided at the center of the connecting plate, and the adjusting belt passes through the inside of the slot. A buckle is provided on the surface of the housing, and the end of the adjusting belt away from the receiving hopper is inserted into the inside of the buckle.

[0013] As an improvement to the above technical solution, the track component is an I-shaped component, and the lower end face of the receiving hopper is provided with an I-shaped track groove. The end of the receiving hopper away from the track component is provided with a connecting block in the track groove, and an elastic component is provided between the track component and the connecting block to connect the two.

[0014] As an improvement to the above technical solution, a rectangular groove is provided on the side of the track groove near the second housing, and an inclined platform is provided on the upper end face of the receiving hopper away from the rectangular groove.

A threaded handwheel is provided at the center of the pot lid. The other end of the handwheel is detachably fixed to the center of the housing. The lower surface of the material gathering component is provided with an inclined plate. A discharge hopper is connected to the lower side of the inclined plate.

[0016] The beneficial effects of this invention are:

[0017] The internal shells, shell one and shell two, form a double-layer lifting function. The first layer of lifting is used to send shell one out of the pot, while the second layer of lifting moves shell two to the outside and extends the receiving hopper. The extended receiving hopper can be used for feeding materials onto the conveyor belt or for creating an inclined state for unloading. This can realize automated feeding, unloading, and sterilization functions in large-scale production. During the sterilization process, the operator only needs to pay attention to unexpected situations, which is not only more efficient but also eliminates direct safety risks to the operator.

Detailed Implementation

[0029] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0030] The sterilizers used in the prior art typically consist of a double-layer structure. The upper layer is usually the pot body used to place items, while the lower layer is usually a heater used to generate high-temperature steam. The heater evaporates water at a high temperature to form high-temperature steam. As the gas pressure continuously increases during the heating process, it forms a high-temperature and high-pressure steam sterilization function. Although it can achieve normal sterilization, in veterinary drug production, this type of sterilizer usually requires the operator to repeatedly load and unload materials. Each operation requires avoiding burns to the operator's arms from the high-temperature steam, which is not only inefficient but also poses a safety risk to the user.

[0031] To resolve the above issues, please refer to Figures 1 to 10 A sterilizer for veterinary drug production is provided, comprising: a pot body 10, a shell 41 and a shell 43 nested inside the pot body 10, and a polymer component 30 covering the outside of the pot body 10.

[0032] Specifically, a lid 11 is detachably mounted on the top of the pot body 10. The second shell 43 moves vertically along the outer wall of the first shell 41. The first shell 41 can move vertically along the center of the pot body 10. Several retractable receiving hoppers 44 are mounted on the outer wall of the second shell 43. The end of the receiving hopper 44 away from the second shell 43 can be tilted downward to form a discharge state. The material gathering component 30 is used to receive the material discharged from the receiving hopper 44.

[0033] The lifting shell 43 and shell 41 form a double-layer lifting structure, which allows the receiving hopper 44 to be retracted into the pot body 10. Combined with the closed pot lid 11, the function of sealing and sterilization can be achieved. In this embodiment, the receiving hopper 44 also needs to be used in conjunction with a conveyor belt. The thickness of the conveyor belt must not exceed the distance between the two receiving hoppers 44.

[0034] After sterilization is completed, the second shell 43 is first extended by lifting the first shell 41, and then the second shell 43 is lifted along the first shell 41, thereby moving all the receiving hoppers 44 to the outside of the pot body 10. At this time, the receiving hoppers 44 are extended and the ends are tilted to form an outward unloading state. The material gathering component 30 covers the outside of the pot body 10, so the dropped material will be collected by the material gathering component 30, thereby completing the material collection operation.

[0035] To improve the structural design of the polymer component 30, please refer to the following for details. Figure 1 and Figure 2 The lower end face of the material gathering component 30 is provided with an inclined plate 32, and the side of the inclined plate 32 located below is connected to the discharge hopper 31.

[0036] The inclined plate 32 with its bottom slope allows the material that falls into the material collection component 30 to slide down one side, and the material is collected at the end of the slide by the discharge hopper 31, and finally sent out. At the end of the discharge hopper 31, packaging equipment or conveying equipment is usually required to transfer the disinfected material to the next stage for processing.

[0037] In one embodiment, see Figure 1 and Figure 2 The upper surface of the pot lid 11 is provided with a pressure gauge 112 and a gas valve 111 that communicate with the inside of the pot body 10. A threaded handwheel 113 is provided at the center of the pot lid 11, and the other end of the handwheel 113 is detachably fixed to the center of the housing 43.

[0038] The pressure gauge 112 is used to test the pressure inside the pot body 10, while the air valve 111 is used to actively release pressure when the internal air pressure is too high. The handwheel 113 is used to install the second housing 43 and the pot lid 11. When the first housing 41 or the second housing 43 is raised or lowered, the pot lid 11 will open accordingly. The pot lid 11 needs to be opened slowly to release pressure slowly.

[0039] To further refine the technical solution, please refer to [link / reference]. Figure 1 and Figure 2A steam generating mechanism 20 is provided at the lower end of the pot body 10. The steam generating mechanism 20 includes a bottom cylinder 22 that is detachably fixed to the pot body 10. An installation groove 23 is provided on one side of the bottom cylinder 22. A heating element 24 is fixed inside the installation groove 23. The heating element 24 is located inside the bottom cylinder 22 and is electrically connected to a heating wire 25.

[0040] The water inside the bottom cylinder 22 is heated by the heating wire 25. The water inside the bottom cylinder 22 is usually transported through a water pipe on the side. It can also be used to replenish water when the water inside is insufficient. A water level gauge is usually installed inside the bottom cylinder 22 to ensure that the water level inside the bottom cylinder 22 is normal. In addition, only a filter screen is usually installed between the bottom cylinder 22 and the pot body 10 to ensure that the steam generated by high-temperature evaporation can smoothly enter the interior of the pot body 10.

[0041] In one embodiment, specifically, a connecting groove is provided at the center of the bottom cylinder 22, extending into the interior of the pot body 10. The interior of the connecting groove is sealed with a drive assembly 40 for driving the lifting and lowering of the first housing 41 and the second housing 43.

[0042] The drive assembly 40 drives housing 41 and housing 43 to produce corresponding lifting functions. For details, please refer to [link / reference]. Figure 2 , Figure 10 The structural design is as follows:

[0043] The drive assembly 40 includes a first motor 4111 and a second motor 4121. The second motor 4121 is fixed inside the first housing 41. The power end of the second motor 4121 is connected to a second lead screw 412 for driving the second housing 43 to rise and fall. The lower end face of the bottom cylinder 22 is fixed to a base frame 21. The first motor 4111 is fixed to the upper end face of the center position of the base frame 21. The power end of the first motor 4111 is connected to a first lead screw 411 for driving the first housing 41 to rise and fall.

[0044] Motor 1 (4111) and Motor 2 (4121) drive lead screw 1 (4111) and lead screw 2 (412) to rotate respectively. The rotating lead screws 1 (4111) and 2 (412) then drive housing 1 (411) and housing 2 (43) to rise and fall respectively. (See section 2 for details.) Figures 7 to 10 The specific lifting structure is implemented as follows:

[0045] A positioning frame 42 is fixed on the upper end face of housing 41. Both the upper and lower ends of housing 43 are integrally formed with a base plate 433. A lead screw 412 is threaded through the base plate 433. A limit groove 434 is opened on the surface of the base plate 433. The positioning frame 42 is inserted into the interior of the limit groove 434. Housing 43 moves up and down linearly along the positioning frame 42. The connecting groove at the center of the bottom cylinder 22 is rectangular. Housing 41 is inserted into and fits against the inner wall of the connecting groove. The lead screw 411 is threaded through the bottom of housing 41.

[0046] The design of the positioning frame 42 creates a nested vertical lifting state between the second housing 43 and the first housing 41. The rotation of the second lead screw 412 installed on the inner side can drive the second housing 43 to rotate. Since the second housing 43 is restricted by the positioning frame 42, a lead screw track is formed, thereby controlling the second housing 43 to rise and fall along the positioning frame 42. Similarly, the rotation of the first lead screw 411 will drive the first housing 41 to rotate. However, since the first housing 41 is located inside the bottom cylinder 22 and is restricted by the rectangular connecting groove, the first housing 41 will not rotate, thus forming a lead screw track as well. That is, the rotation of the first lead screw 411 drives the first housing 41 to rise and fall.

[0047] In the aforementioned solution, the receiving hopper 44 is powered independently, requiring additional power equipment for operation. This results in an excessive number of power devices needing to be installed between structures, increasing the complexity of the solution. To avoid this issue, please refer to [the relevant documentation / reference]. Figures 2 to 6 The surface of the second housing 43 is provided with at least two vertically arranged positioning grooves 431. A track component 45 that is detachably fixed to the first housing 41 is horizontally inserted into the positioning groove 431. A receiving hopper 44 is arranged at the upper end of the track component 45. An adjusting belt 442 is arranged on the side of the receiving hopper 44 near the second housing 43. The other end of the adjusting belt 442 is fixed to the inner wall of the second housing 43.

[0048] The positioning groove 431 ensures that the track component 45 can move vertically. This is to avoid conflict between the lifting and lowering of the housing 43 and the track component 45. The receiving hopper 44 on the track component 45 is connected by an adjusting belt 442. When the housing 43 descends, the adjusting belt 442 will pull down, thereby driving the receiving hopper 44 to move linearly along the track component 45, thus retracting the receiving hopper 44 into the interior. In this design, there are no additional restrictions on the position of the adjusting belt 442. However, during the descent of the housing 43, the angle of inclination between it and the track component 45 may become too large, potentially causing jamming. To avoid this problem, please refer to [the relevant documentation]. Figures 2 to 6 The specific structural design is as follows:

[0049] A connecting plate 452 is integrally formed between two adjacent track components 45 at one end near the housing 43. A slot 453 is provided at the center of the connecting plate 452. The adjusting belt 442 passes through the inside of the slot 453. A buckle plate 432 is provided on the surface of the housing 43. The end of the adjusting belt 442 away from the receiving hopper 44 is inserted into the inside of the buckle plate 432.

[0050] Positional constraints are achieved through the connecting plate 452, ensuring that the adjusting belt 442 only experiences tilting and rope compression at its end. The pulling action here only affects the adjusting belt 442. When the adjusting belt 442 shifts, the force on the receiving hopper 44 remains horizontal, preventing jamming. The end of the adjusting belt 442 is secured by a buckle plate 432, facilitating later disassembly or replacement. The buckle plate 432 can be further reinforced using clips, bolts, or other fixing methods. In this embodiment, the retracted state of the receiving hopper 44 is connected to the descent of the housing 43. Further control of the operation in the extended state of the receiving hopper 44 is needed; please refer to Figures 2 to 3. Figure 6 The structural design is as follows:

[0051] The track component 45 is an I-shaped component, and the lower end face of the receiving hopper 44 is provided with an I-shaped track groove 443. The end of the receiving hopper 44 away from the track component 45 is provided with a connecting block 444 in the track groove 443. An elastic component 451 is provided between the track component 45 and the connecting block 444 to connect the two.

[0052] The unfolding operation is provided by the rebound of the elastic element 451. That is, when the housing 43 is raised, the rebound of the elastic element 451 will restore the hopper 44 to its original position. In this embodiment, the elastic element 451 can be a structure or workpiece with elastic deformation recovery, such as a spring or elastic rope.

[0053] In the aforementioned technical solution, the receiving hopper 44 cannot automatically unload material. To further improve this function of the receiving hopper 44, please refer to [link / reference needed]. Figure 5 and Figure 6 Specifically, a rectangular groove 445 is provided on the side of the track groove 443 near the housing 43, and an inclined platform 441 is provided on the upper end face of the receiving hopper 44 away from the rectangular groove 445.

[0054] A rectangular groove 445 is provided on one side near the second housing 43. The track component 45 of the I-shaped component forms a linear movement track constraint, while the rectangular groove 445 can only form a lateral constraint on the left and right sides. This causes the receiving hopper 44 to have a change in vertical tilt angle. When there is material on the receiving hopper 44 and the second housing 43 moves to its highest position, the outermost end of the track component 45 will get stuck in the rectangular groove 445. Since the rectangular groove 445 is relatively short compared to the length of the entire receiving hopper 44, combined with the pressure of the material above, the receiving hopper 44 will tilt, thus forming a discharge state. The material will fall into the inside of the material gathering component 30 in a tilted manner. To cancel the discharge state, it is only necessary to control the second housing 43 to descend. Here, there may be squeezing at the end of the I-shaped groove, which may cause jamming. Therefore, the junction of the rectangular groove 445 and the track groove 443 needs to be designed as an arc-shaped rounded corner. This can ensure that the groove can accurately squeeze into the track component 45, thereby ensuring subsequent movement, discharge and other operations.

[0055] In this embodiment, the elastic element 451 adopts a structure design in which the elastic rope is wrapped around the spring on the outside. The elastic rope positions the structure of the spring to prevent the spring from becoming misaligned. The spring itself has a stronger deformation recovery ability and can provide a better recovery effect.

[0056] The above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to limit it. Anyone skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
