Description

Technical Field

[0001] The present invention relates to the technical field of transport devices, in particular to an oxygen-inhibiting transport device for microbial raw materials. Background Art

[0002] Microbial raw materials refer to biologically active substances that are directly derived from microorganisms or produced through microbial metabolism, fermentation and other processes. They are widely used in food, medicine, agriculture, environmental protection, industry and other fields. However, when using microbial raw materials, special transportation equipment is required to transport oxygen-sensitive microbial raw materials. By suppressing the oxygen content, a stable low-oxygen or anaerobic environment is provided for microorganisms to maintain their activity and stability.

[0003] To this end, the patent with publication number CN117923012A discloses an oxygen-inhibiting transportation device for microbial raw materials, which can improve the oxygen-inhibiting transportation effect of microbial raw materials, achieve better guarantee of the transportation quality of microbial raw materials, and is convenient to maintain. The storage and unloading operations of the microbial raw materials are relatively convenient and practical. The device comprises a container body and an external frame. The container body is fixedly connected to the external frame. A reset guide bar and a support limit bar are fixedly connected to the container body. A plurality of first splicing box plates and a plurality of second splicing box plates are arranged between the reset guide bar and the support limit bar. An adjusting screw is rotatably connected to the container body, an adjusting screw sleeve is threadedly connected to the adjusting screw, and an end storage box is fixedly connected to the adjusting screw sleeve. The plurality of first splicing box plates and the plurality of second splicing box plates are all rotatably connected to the adjusting screw sleeve. Four ventilation tubes, four first end tubes and four second end tubes are fixedly connected to the external frame.

[0004] The above-mentioned microbial raw material oxygen suppression transport device is more convenient in storage and unloading operations by splicing box panels, but the single storage space inside it cannot be adjusted, which makes the space mismatched with the raw material volume, and may cause uneven gas distribution in the space, affecting the oxygen suppression effect. For some microbial raw materials that are sensitive to space, the fixed space may not provide the optimal spatial conditions required for their growth or preservation, thereby reducing the survival rate or quality of the raw materials. Summary of the Invention

[0005] The purpose of the present invention is to provide a microbial raw material oxygen suppression transport device to solve the defect that the existing microbial raw material oxygen suppression transport device is inconvenient to adjust the space.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a microbial raw material oxygen-inhibiting transportation device, comprising an outer shell; base plates are installed at the corners inside the outer shell, and chambers are provided at the tops of the base plates, vertical plates are fixed inside the outer shell at both ends of the chamber, air-containing cavities are installed on the inner walls at both ends of the outer shell, and replacement gas cavities are installed in the middle of the chamber; the chamber includes a sleeve installed on one side of both ends of the chamber, the side walls of the vertical plates inside the sleeve are provided with screws, and a pulley mechanism is connected to one end between the screws, a servo motor is installed on one side of the screw, and a door body is hinged on one side of the chamber.

[0007] Preferably, the chamber is made of a metal bellows, a groove body is provided at the bottom end of one side of the chamber, and a sealing strip is provided at the bottom of the groove body.

[0008] Preferably, a second spring is installed at the top of the sealing strip, and the second springs are evenly spaced about the top of the sealing strip, and a suction cup strip is provided at the bottom of the sealing strip. Under the pressure of the second spring, the suction cup strip adheres to the surface of the bottom plate to ensure the sealing effect of the chamber.

[0009] Preferably, a sealing ring is provided on the inner side of the door body, a sealing groove is provided on the outer side of the chamber, and the shapes of the sealing groove and the sealing ring are consistent, and card slots are fixed at both ends of the door body.

[0010] Preferably, a connecting block is fixed at each end of the chamber on one side of the slot, and a clamping block is provided inside the connecting block. The bottom of the clamping block is angled, and a sliding structure is formed between the clamping block and the connecting block. Due to the angled design, when the door closes and the slot approaches, the clamping block is squeezed upward, achieving automatic locking.

[0011] Preferably, a first spring is installed inside each of the clamping blocks, and the top of the first spring is connected to the connecting block, and a pull ring is welded to the top of each of the clamping blocks. The rebound force of the first spring pushes the clamping block to instantly engage with the clamping slot when the clamping block enters the clamping slot.

[0012] Preferably, the sleeve is provided with an internal thread, and the sleeve and the screw rod are threadedly connected. Through the threaded connection, the chamber can be expanded and contracted, thereby automatically adjusting the space size.

[0013] Preferably, the bottom of the air-containing cavity is connected to an exhaust pipe, and a vacuum pump is installed at one end of the exhaust pipe away from the air-containing cavity. One end of the vacuum pump is connected to a connecting pipe, and the end of the connecting pipe away from the vacuum pump is connected to the chamber.

[0015] Preferably, a connecting frame is provided at both ends of the bottom plate, and a sliding structure is formed between the connecting frame and the chamber. An airbag is installed at both ends of the connecting frame, and a sealing gasket is provided at the bottom of the chamber at the bottom of the airbag. The airbag is located at the bottom of the chamber side wall and fits tightly with the chamber surface to ensure the sealing of the chamber.

[0016] Compared with the prior art, the present invention has the following advantages: the microbial raw material oxygen suppression transport device can classify and place different microbial raw materials, and can adjust the space size according to the characteristics and needs of the raw materials while ensuring the sealing, which is conducive to maintaining the stability and quality of the raw materials and reducing losses during transportation;

[0017] By setting up a chamber, there are 4 groups of chambers in the device, and the chamber is made of metal bellows, so that the size of each group of container space can be adjusted. The screw rod set on one side of the chamber realizes the automation of container space adjustment, which increases convenience. Different microbial raw materials can be easily classified and placed in multiple groups. The space size can be accurately controlled according to the characteristics and needs of the raw materials to ensure uniform gas distribution in the space and good oxygen suppression effect, thereby ensuring the activity and quality of the raw materials.

[0018] Furthermore, an airbag is provided at the bottom of the chamber. When the chamber is expanded and contracted to adjust the size of the space, due to the characteristics of the gas in the airbag, the gas will be transferred with the compression when the chamber changes, but the deformation of the chamber does not change the volume change between the airbags. Therefore, no matter how the chamber expands and contracts, the airbag always fits tightly with it, ensuring the sealing while achieving space adjustability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1-10 The present invention provides an oxygen-inhibiting transport device for microbial raw materials, comprising a shell 1; bottom plates 5 are installed at the corners inside the shell 1, and chambers 2 are provided on the tops of the bottom plates 5, and vertical plates 6 are fixed inside the shell 1 at both ends of the chamber 2. The chamber 2 includes a sleeve 25 installed on one side of both ends of the chamber 2, and the side walls of the vertical plates 6 inside the sleeve 25 are provided with screw rods 22, and one end between the screw rods 22 is connected to a pulley mechanism 24, a servo motor 23 is installed on one side of the screw rod 22, a door body 21 is hinged on one side of the chamber 2, the chamber 2 is made of a metal bellows, an internal thread is provided inside the sleeve 25, and the sleeve 25 and the screw rod 22 are threadedly connected;

[0032] Reference Figure 3 and Figure 4As shown, the chamber 2 is provided with four groups, which can be classified to place different types of microbial raw materials. First, the container volume of the chamber 2 is adjusted according to the physiological characteristics of the microbial raw materials to make it suitable for different microorganisms. The servo motor 23 is started to drive the screw rod 22 to rotate. The two groups of screw rods 22 rotate simultaneously through the pulley mechanism 24. Because the sleeve 25 and the screw rod 22 are threadedly connected, the sleeve 25 is driven to reciprocate when the screw rod 22 rotates, thereby pulling the chamber 2 to one side to stretch or contract. Because the chamber 2 is made of a metal bellows, its internal space changes during expansion and contraction. When the space size is adjusted to the appropriate size, the servo motor 23 is stopped.

[0033] A groove body 26 is provided at the bottom end of one side of the chamber 2, and a sealing strip 261 is provided at the bottom of the groove body 26. A second spring 263 is installed at the top of the sealing strip 261, and the second springs 263 are evenly spaced about the top of the sealing strip 261. A suction cup strip 262 is provided at the bottom end of the sealing strip 261. A connecting frame 51 is provided at both ends of the bottom plate 5, and a sliding structure is formed between the connecting frame 51 and the chamber 2. Air bags 52 are installed at both ends of the connecting frame 51, and a sealing gasket 53 is provided at the bottom end of the chamber 2 at the bottom of the air bag 52.

[0034] Reference Figure 5 、 Figure 6 and Figure 10 As shown, when the chamber 2 is in the process of expansion and contraction, its bottom slides inside the connecting frame 51. Since the interior of the airbag 52 is filled with gas, during the process of the chamber 2 being stretched and deformed, as the airbag 52 is squeezed and changed, the gas inside will be transferred with the squeezing, and will always be in close contact with the surface of the chamber 2. The sealing gasket 53 is at the bottom of the airbag 52 to improve the sealing effect. The metal bellows material of the chamber 2 makes the space in a sealed state to the greatest extent. After the space adjustment of the chamber 2 is completed, the second spring 263 inside the groove body 26 pushes the sealing strip 261 to be squeezed and fitted with the surface of the bottom plate 5 through tension. A suction cup strip 262 is provided at the bottom of the sealing strip 261. Under the action of pressure, the suction cup strip 262 is adsorbed and fitted with the smooth surface of the bottom plate 5, thereby ensuring the sealing effect.

[0035] A sealing ring 213 is provided on the inner side of the door body 21, and a sealing groove 214 is provided on the outer side of the chamber 2, and the shapes of the sealing groove 214 and the sealing ring 213 are consistent. A card slot 211 is fixed at both ends of the door body 21, and a connecting block 212 is fixed at both ends of the chamber 2 on one side of the card slot 211, and a card block 215 is provided inside the connecting block 212. The bottom of the card block 215 is beveled, and a sliding structure is formed between the card block 215 and the connecting block 212. A first spring 216 is installed inside the card block 215, and the top of the first spring 216 is connected to the connecting block 212. A pull ring 217 is welded to the top of the card block 215.

[0036] Reference Figure 5 、 Figure 6 、 Figure 8 and Figure 9 As shown, after the space adjustment of chamber 2 is completed, the pull ring 217 is pulled upward to drive the card block 215 to move upward, so that the card block 215 is away from the card slot 211. After the card slot 211 is disengaged, the door body 21 is flipped upward, and the inner wall of the chamber 2 is disinfected with a disinfectant spray. After natural drying, the door body 21 is flipped over to close it. During the flipping process, the card slot 211 contacts the bottom of the card block 215. The bottom of the card block 215 is beveled, and one side of the card slot 211 matches its shape. When the door body 21 When flipped and squeezed inward, the card slot 211 pushes the card block 215 to slide upward at an oblique angle. When the door body 21 is closed tightly, the card block 215 slides to the inside of the card slot 211. The first spring 216 squeezes the card block 215 downward instantly through the rebound force and is fixed with the card slot 211, making it easy to open or close the door body 21. When closed, the sealing ring 213 is squeezed into the sealing groove 214, fully filling the gap between the door body 21 and the chamber 2, ensuring the sealing effect of the chamber 2.

Both ends of the replacement gas chamber 4 are connected to an inflation pipe 41, and an electromagnetic valve group 42 is installed on the outside of the chamber 2 at one end of the inflation pipe 41.

[0038] Reference Figure 2-Figure 4 As shown, after the internal preparation of chamber 2 is completed, the vacuum pump 31 is started first to evacuate the interior of chamber 2. A vacuum sensor is installed in chamber 2 to monitor the pressure in the container in real time to ensure that the target vacuum degree is reached. Then the solenoid valve group 42 is controlled to transport the inert gas prepared in the replacement gas chamber 4 to the interior of chamber 2 to realize the vacuum-filling-balance cycle operation. The number of replacements is set according to the container volume and microbial requirements. After the protective gas pre-filling is completed, different microbial raw materials are placed in different chambers 2 to achieve classified placement.
