Description

Technical Field

[0001] This application relates to the field of steam sterilizer technology, specifically to an automatic feeding device for a steam sterilizer. Background Technology

[0002] During food processing, due to production conditions and processing techniques, the microbial content in products may exceed the standard. Therefore, high-temperature steam is needed to sterilize and disinfect the food during processing, thereby reducing the microorganisms in the product and obtaining products that meet the factory standards. A steam sterilizer is a device that uses high-temperature steam for sterilization, mainly used to kill microorganisms and ensure the sterility of items.

[0003] An existing patent (publication number: CN211241587U) discloses a steam sterilizer, which includes: a steam sterilizer cabinet, a transport cart, a sterilization cart, a tray, and a control device. A sterilization inner liner is fixedly installed inside the steam sterilizer cabinet. An air inlet pipe is fixedly connected to one side of the top of the sterilization inner liner. A steam generator is fixedly connected to the bottom of the air inlet pipe. A water pump is fixedly connected to the steam generator. A water tank is fixedly connected to the bottom of the water pump. A water inlet is opened on one side of the water tank. An inlet valve is fixedly installed on the water inlet. An air outlet pipe is fixedly connected to the other side of the top of the sterilization inner liner. A vacuum pump is fixedly connected to the bottom of the air outlet pipe. Control valves are fixedly installed on both the air inlet pipe and the air outlet pipe.

[0004] Existing steam sterilizers typically require manual feeding of the materials to be sterilized into the machine body. However, this method carries certain operational risks and results in poor uniformity of sterilization after feeding, leading to a decline in the quality of material sterilization. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an automatic feeding device for a steam sterilizer, which has the advantages of avoiding manual operation, reducing operational risks, and ensuring more uniform steam sterilization after feeding. This solves the problem that current operating methods have certain operational risks and result in poor uniformity of material sterilization after feeding, leading to a decline in the quality of material sterilization.

[0006] To achieve the above objectives, this application provides the following technical solution: an automatic feeding device for a steam sterilizer, comprising a sterilizer body, an extension frame fixedly connected to one side of the sterilizer body, bottom grooves provided at the top of the extension frame and at the bottom of the sterilizer body, a support component slidably connected to the inner wall of the bottom groove, a material sieve provided on the inner wall of the support component, a driving device provided on the outer surface of the sterilizer body, a transverse mechanism engaged at the output end of the driving device, the bottom of the transverse mechanism fixedly connected to the support component, a bottom groove provided inside the sterilizer body, an upper steam pipe provided inside the bottom groove, a sealing door slidably connected to the inner wall of the sterilizer body, and a steam extraction device provided at the top of the sterilizer body.

[0007] The above solution involves setting a bottom trough that connects the extension frame and the sterilizer body. When steam sterilization of materials is required, the materials are laid on the material screen and placed inside the support assembly. The support assembly is located on the extension frame. The drive device, in conjunction with the drive lateral movement mechanism, slides laterally at the top inside the sterilizer body to provide displacement driving force for the support assembly. This allows the material screen to move together into the sterilizer body until it is completely inside the sterilizer body. Then, the steam pipe inside the bottom trough evenly transmits steam to the sterilizer body to contact the materials on the material screen. This allows the materials to be automatically fed into the sterilizer body for uniform sterilization, avoiding manual operation, reducing operational risks, and ensuring more uniform steam sterilization after feeding.

[0008] Furthermore, the support assembly includes a support frame, and a positioning frame is fixedly connected to the inner wall of the support frame. The number of positioning frames is set to two. A bottom slide is fixedly connected to the bottom of the support frame, and the bottom slide is slidably connected to the inner wall of the bottom slide groove.

[0009] The above scheme uses a support frame to support two sets of positioning frames on the inside, forming a certain gap. This provides a support function with a certain gap for the material screen, allowing the steam to have sufficient flow space to contact the material on the inside, thus achieving a better sterilization effect.

[0010] Furthermore, the driving device includes a motor, and a drive shaft is fixedly mounted on the output end of the motor. A first gear and a second gear are fixedly connected to the outer surface of the drive shaft, and both the first gear and the second gear mesh with the top of the transverse mechanism.

[0011] With the above scheme, after the motor is started, the drive shaft rotates, and together with the first gear and the second gear, it can provide a balanced and stable driving force for the transverse mechanism, so that the transverse mechanism can move back and forth inside the sterilizer body to drive the support frame to automatically feed and unload materials.

[0012] Furthermore, the transverse movement mechanism includes transverse movement racks, and there are two sets of transverse movement racks. A side slide rail is fixedly connected to one side of each set of transverse movement racks. The side slide rail is slidably connected to the inner wall of the sterilizer body. A connecting plate is fixedly connected to the bottom of each set of transverse movement racks. The connecting plate is fixedly connected to the top of the support frame.

[0013] With the above scheme, when the motor starts, the drive shaft drives the first gear and the second gear to rotate together, thereby driving the two sets of transverse racks to slide laterally along the inner wall of the sterilizer body. This causes the connecting plate and the support frame below to move together, thereby causing the bottom slide seat at the bottom of the support frame to slide along the inner wall of the bottom slide groove until the support frame is completely inside the sterilizer body and stops, thus realizing the automatic feeding process, making the feeding process more convenient and efficient and eliminating the need for manual operation.

[0014] Furthermore, the steam extraction device includes a steam pump, and a steam extraction pipe is provided at the bottom of the steam pump, which is connected to the interior of the sterilizer body.

[0015] With the above scheme, through the combined action of the steam pump and the steam extraction pipe, when a large amount of steam is generated inside the sterilizer body and the sterilizing liquid continues to flow upward, the steam pump can generate suction force after starting, and work with the steam extraction pipe to extract and discharge the excess steam.

[0016] Furthermore, the number of steam pipes is set to several, and the several steam pipes are evenly distributed inside the bottom groove.

[0017] With the above scheme, by setting up multiple steam pipes, when a large amount of steam is generated inside the sterilizer body, it is squeezed into the steam pipe and flows upward. After colliding with the bottom of the material screen, it is dispersed, so that the steam can rise from the gaps of the material screen and fully contact the material to achieve a uniform sterilization effect.

[0018] Furthermore, the inner wall of the sterilizer body is provided with a side sliding groove, and the sealing door is slidably connected to the inner wall of the side sliding groove.

[0019] The above solution provides lateral sliding space for the sealed door through the side sliding groove, making it easy to open and close.

[0020] Furthermore, the top of the inner wall of the sterilizer body is symmetrically provided with side partitions, and a heat-insulating sleeve is fixedly connected between the side partitions.

[0021] With the above scheme, the side partitions are located on the sides of the two sets of transverse racks, which can act as a barrier to prevent high-temperature steam from entering and affecting the smoothness of the transverse rack sliding. The heat insulation sleeve plays a role in blocking and supporting the drive shaft.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This automatic feeding device for a steam sterilizer features a bottom trough connected to an extension frame and the sterilizer body. When steam sterilization is required, the material is laid on a material sieve and placed inside a support assembly. The support assembly is located on the extension frame. A drive device, in conjunction with a drive lateral movement mechanism, slides laterally at the top inside the sterilizer body, providing displacement driving force for the support assembly. This allows the material sieve to move into the sterilizer body until it is completely inside. Steam is then evenly delivered to the sterilizer body through an upward steam pipe inside the bottom trough, contacting the material on the sieve. This allows the material to be automatically fed into the sterilizer body for uniform sterilization, avoiding manual operation, reducing operational risks, and ensuring more uniform steam sterilization after feeding.

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 5 This embodiment of an automatic feeding device for a steam sterilizer includes a sterilizer body 1. An extension frame 2 is fixedly connected to one side of the sterilizer body 1. Bottom grooves 3 are provided on the top of the extension frame 2 and the bottom of the sterilizer body 1. A support assembly 4 is slidably connected to the inner wall of the bottom groove 3. A material sieve 5 is provided on the inner wall of the support assembly 4. A drive device 6 is provided on the outer surface of the sterilizer body 1. A transverse movement mechanism 7 is engaged at the output end of the drive device 6. The bottom of the transverse movement mechanism 7 is fixedly connected to the support assembly 4. A bottom groove 8 is provided inside the sterilizer body 1. An upper steam pipe 9 is provided inside the bottom groove 8. A sealing door 10 is slidably connected to the inner wall of the sterilizer body 1. A steam extraction device 11 is provided on the top of the sterilizer body 1. The device is connected to the extension frame 2 and the sterilizer body 1 by means of a connection between the extension frame 2 and the sterilizer body 1. When steam sterilization of materials is required, the bottom trough 3 is used. The materials are laid on the material screen 5 and placed inside the support component 4. At this time, the support component 4 is located on the extension frame 2. The drive device 6, in conjunction with the drive lateral movement mechanism 7, slides and moves laterally at the top inside the sterilizer body 1 to provide displacement driving force for the support component 4. This allows the material screen 5 to move together into the sterilizer body 1 until it is completely inside the sterilizer body 1 and then stops. The steam pipe 9 set inside the bottom trough 8 evenly transmits steam into the sterilizer body 1 to contact the materials on the material screen 5, so that the materials can be automatically fed into the sterilizer body 1 for uniform sterilization. This avoids manual operation, reduces operational risks, and makes the steam sterilization more uniform after feeding.

[0033] Please see Figure 2 and Figure 4 The support component 4 includes a support frame 401, and a positioning frame 402 is fixedly connected to the inner wall of the support frame 401. There are two positioning frames 402. A bottom slide 403 is fixedly connected to the bottom of the support frame 401. The bottom slide 403 is slidably connected to the inner wall of the bottom slide groove 3. The support frame 401 supports the two sets of positioning frames 402 on the inner side to form a certain interval, which facilitates the provision of a certain interval support for the material screen 5, so that the steam has enough flow space to contact the material on the inner side, and achieves a better sterilization effect.

[0034] Please see Figure 1 and Figure 4The drive device 6 includes a motor 601, and a drive shaft 602 is fixedly installed at the output end of the motor 601. A first gear 603 and a second gear 604 are fixedly connected to the outer surface of the drive shaft 602. The first gear 603 and the second gear 604 mesh with the top of the transverse mechanism 7. After the motor 601 is started, the drive shaft 602 rotates, and together with the first gear 603 and the second gear 604, they can provide a balanced and stable driving force for the transverse mechanism 7, so that the transverse mechanism 7 can make reciprocating motion inside the sterilizer body 1, driving the support frame 401 to make reciprocating motion, providing it with automatic loading and unloading driving force, thereby avoiding the risks of manual operation.

[0035] Please see Figure 3 and Figure 4 The transverse movement mechanism 7 includes two sets of transverse movement racks 701. Each set of transverse movement racks 701 has a side slide rail 702 fixedly connected to one side. The side slide rail 702 is slidably connected to the inner wall of the sterilizer body 1. Each set of transverse movement racks 701 has a connecting plate 703 fixedly connected to the bottom. The connecting plate 703 is fixedly connected to the top of the support frame 401. When the motor 601 is started, the drive shaft 602 drives the first gear 603 and the second gear 604 to rotate together, thereby driving the two sets of transverse movement racks 701 to slide laterally along the inner wall of the sterilizer body 1. This causes the connecting plate 703 and the support frame 401 below to move together, thereby causing the bottom slide seat 403 at the bottom of the support frame 401 to slide on the inner wall of the bottom slide groove 3 until the support frame 401 is completely inside the sterilizer body 1 and then stops, thus realizing the automatic feeding process, making the feeding process more convenient, efficient and without manual operation.

[0036] In this embodiment, an automatic feeding device for a steam sterilizer utilizes a bottom sliding groove 3 connected to the extension frame 2 and the sterilizer body 1 to provide sliding space for the bottom sliding seat 403 at the bottom of the support frame 401. When material needs to be fed, the support frame 401 supports two sets of positioning frames 402 on the inner side, forming a certain interval, which facilitates the provision of spaced support for the material sieve 5, allowing the steam to have sufficient flow space to contact the material inside. The motor 601, in conjunction with the first gear 603 and the second gear 604, provides a balanced lateral driving force to the transverse rack 701, enabling the transverse rack 701 to reciprocate inside the sterilizer body 1 and drive the support frame 401. The system performs a reciprocating motion to achieve an automatic feeding process, making the feeding process more convenient, efficient, and requiring no manual operation. Through the setting of multiple steam pipes 9, a large amount of steam is squeezed into the interior of the steam pipes 9 and flows upward. After colliding with the bottom of the material screen 5, the steam disperses, allowing it to rise from various gaps in the material screen 5 and fully contact the material to achieve a uniform sterilization effect. With the cooperation of the steam pump 1101 and the steam extraction pipe 1102, when a large amount of steam is generated inside the sterilizer body 1, it continues to flow upward after sterilization. After the steam pump 1101 is started, it can generate suction force to work with the steam extraction pipe 1102 to extract and discharge excess steam, preventing a large amount of steam from remaining inside the sterilizer body 1 and causing adverse effects on the material.

[0037] It should be noted that...

[0038] The working principle of the above embodiments is as follows:

[0039] The support frame 401 supports two sets of positioning frames 402 on the inner side, forming a certain gap. The material screen 5 is placed above the positioning frames 402. When feeding is required, the motor 601 is started, causing the drive shaft 602 to rotate. This drives the two sets of transverse racks 701 to slide laterally along the inner wall of the sterilizer body 1, thereby moving the connecting plate 703 and the support frame 401 below together. This causes the bottom sliding seat 403 at the bottom of the support frame 401 to slide along the inner wall of the bottom sliding groove 3. The process continues until the support frame 401 is completely inside the sterilizer body 1, so that both the support frame 401 and the material sieve 5 are positioned above the steam passage inside the sterilizer body 1. The sterilizer body 1 is then closed by pushing the sealing door 10. When steam enters, it is squeezed through multiple sets of steam pipes 9 and flows upward to contact the material sieve 5, allowing the steam to flow evenly to the surface of the material sieve 5 and make full contact with the material. At the same time, the steam pump 1101 starts and works with the steam extraction pipe 1102 to extract and discharge excess steam.
