Description

Technical Field

[0001] This invention relates to the field of reagent storage equipment technology, and in particular to a chemical reagent storage combination cabinet. Background Technology

[0002] Universities and enterprises typically have their own reagent storage rooms, which are equipped with cabinets for storing various chemical reagents. As the demand from laboratories increases, the types and quantities of chemical reagents in the storage rooms also increase. Therefore, it is necessary to increase the types and quantities of storage cabinets to meet the storage needs of a large number of different types of reagents.

[0003] In particular, university laboratories have a wide range of experiments that do not involve production, resulting in a large variety of chemical reagents and a small inventory of each type. This leads to a large number of storage cabinets for these reagents, which take up a significant amount of space.

[0004] Due to the fixed space and layout limitations of the storage room, storage cabinets cannot be added arbitrarily. The storage cabinets occupy a large area and can only be placed side by side. Different cabinets store different types of reagents. Because there are too many types of reagents, they need to be vented separately. There are many vents and the types of exhaust are mixed, making it difficult to centrally process or collect the gases. Summary of the Invention

[0005] The purpose of this invention is to provide a chemical reagent storage combination cabinet to solve the problems existing in the prior art. Multiple stacked storage unit cabinets only need to be equipped with an external exhaust pipe on the top cabinet to achieve exhaust. Fewer exhaust pipes are needed, and the gas can be easily concentrated and processed.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] This invention provides a chemical reagent storage cabinet, comprising at least one storage unit cabinet. Each storage unit cabinet includes a cabinet body, with an exhaust device located on one side of the cabinet body. The exhaust device communicates with the reagent storage space inside the cabinet body via an air intake. A fixed protrusion is located at each of the four corners of the bottom of the cabinet body, and an exhaust groove is located at each of the four corners of the top of the cabinet body. An exhaust pipe connects at least one of the fixed protrusions to its corresponding exhaust groove. The exhaust device communicates with the exhaust pipe via an exhaust port. The top of the exhaust pipe communicates with a vent hole penetrating the exhaust groove via a one-way valve that allows only one-way exhaust, and the bottom of the exhaust pipe communicates with a vent hole penetrating the fixed protrusion via a one-way valve that allows only one-way intake. The fixed protrusion can be sealed and engaged within its adjacent exhaust groove. An exhaust pipe can be externally connected to the top of the exhaust groove. Therefore, when multiple storage unit cabinets are stacked, exhaust can be achieved by connecting an exhaust pipe to the exhaust groove of the topmost storage unit cabinet.

[0008] Optionally, the exhaust device includes a negative pressure partition and a purification partition. The bottom of the purification partition is connected to the reagent storage space through a purification air intake port, and the top of the purification partition is connected to the negative pressure partition through a negative pressure air intake port. The negative pressure partition is connected to the exhaust pipe through the exhaust port. The exhaust port is a negative pressure exhaust port.

[0009] Optionally, the purification partition includes an acidic filter layer and an alkaline filter layer, and the purification air intake includes an acidic air intake and an alkaline air intake. The acidic filter layer is connected to the reagent storage space through the acidic air intake, and the alkaline filter layer is connected to the reagent storage space through the alkaline air intake. The acidic filter layer and the alkaline filter layer are respectively connected to the negative pressure partition through their respective negative pressure air intakes, and an electrically controlled valve is provided at the negative pressure air intake.

[0010] Optionally, the negative pressure partition includes a first negative pressure device and a second negative pressure device; the acidic filter layer is connected to the first negative pressure device through a negative pressure intake port, and the alkaline filter layer is connected to the second negative pressure device through a negative pressure intake port; an exhaust pipe is respectively provided between the two fixed protrusions near the exhaust device and their respective upper and lower corresponding exhaust grooves, the first negative pressure device is connected to one of the exhaust pipes through an exhaust port, and the second negative pressure device is connected to the other exhaust pipe through an exhaust port.

[0011] Optionally, both the fixing protrusion and the inner wall of the air guide hole of the exhaust groove are provided with anti-corrosion conical film, and a broken annular rubber sealing ring is provided between the anti-corrosion conical film of the exhaust groove and the inner wall of the exhaust groove for sealing when the fixing protrusion is embedded in the exhaust groove.

[0012] Optionally, the cabinet has a door on the side away from the exhaust device, and the door has a detachable control panel. The control panel is used for reagent storage and retrieval and user information input and storage during human-computer interaction. The side wall of the storage unit cabinet is provided with multiple data transmission interfaces and power supply interfaces. The data transmission interfaces can connect multiple storage unit cabinets via wired network data transmission. The side wall of the storage unit cabinet is also provided with a power supply interface. The power supply interface can be connected to a 12V / 24V power supply independently, or it can be powered through the power supply interface on an adjacent storage unit cabinet. All cabinets can be controlled by installing a control panel on the storage unit cabinet. The control panel can be moved and removed, and installed in different cabinet positions according to usage frequency and operating height.

[0013] Optionally, the cabinet door of the storage unit is equipped with an electronic lock, and the electronic lock can be controlled via a control panel.

[0014] Optionally, the control terminal of the storage unit cabinet is controlled by a mobile phone terminal. The mobile phone terminal can record reagent storage and retrieval and user information, and can confirm identity through face or fingerprint, and can confirm items by scanning codes or NFC scanning through the mobile phone camera. The cabinet body is provided with a cabinet door on the side away from the exhaust device, and the cabinet door is equipped with an electronic lock. The opening and closing of the electronic lock can be controlled by the mobile phone terminal.

[0015] Optionally, the electronic lock can be a passive or active lock. Passive locks can be opened using, for example, NFC. The NFC panel can be set on the front of the storage unit cabinet or on the control panel, which is convenient to operate, saves costs, and can be used in places without power. Active locks can be opened using Bluetooth. Bluetooth can be powered by a separate battery. An additional advantage of separate power supply is that it can detect the opening and closing status of the cabinet door.

[0016] The present invention achieves the following technical effects compared to the prior art:

[0017] The chemical reagent storage cabinet provided by this invention allows for efficient stacking within limited space, preventing the reagent room from being unable to accommodate too many cabinets due to each cabinet occupying its own space. Furthermore, it not only overcomes the limitations of a planar layout but also allows for vertical stacking of storage cabinets within a limited area, increasing the types and quantities of reagents that can be stored. Regardless of the number of cabinets stacked, only one exhaust vent is provided vertically for venting. It eliminates the need for separate venting for acid and alkali reagents in the vertically stacked cabinets; even mixed emissions can be separated. There is no need for separate venting for acidic or alkaline reagents; all gases are uniformly discharged through an exhaust pipe at the top of the cabinet, avoiding the drawbacks of multiple exhaust vents, inconsistent exhaust types, and difficulties in centralized gas treatment or collection.

[0018] The storage combination cabinet of the present invention has good versatility in storing reagents. Both acidic and alkaline reagents can be placed in the same cabinet. Each cabinet is equipped with separate acidic and alkaline exhaust ports. Different types of exhaust ports are opened and closed according to the type of reagent, which improves the versatility of the storage cabinet. If the type of reagent is changed, the cabinet does not need to be changed and the cabinet can be reused.

[0019] The control terminal of this invention can be a control panel or a mobile terminal, which can be selected and configured according to the actual usage. When there are too many people taking and returning reagents, the mobile terminal can meet the needs of a large number of people to operate and take reagents at the same time without queuing in front of the control panel, thus improving the efficiency of reagent taking and returning. In the process of storing and retrieving special reagents used in special experiments, the operators need to wear full protective clothing. It is inconvenient to operate a mobile phone while wearing protective clothing, so it is necessary to operate through the control panel. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The purpose of this invention is to provide a chemical reagent storage combination cabinet to solve the problems existing in the prior art. Multiple stacked storage unit cabinets only need to be equipped with an external exhaust pipe on the top cabinet to achieve exhaust. Fewer exhaust pipes are needed, and the gas can be easily concentrated and processed.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] This embodiment provides a chemical reagent storage cabinet, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the system includes at least one storage unit cabinet 100. The storage unit cabinet 100 includes a cabinet body 1. An exhaust device is provided on one side of the cabinet body 1, and the exhaust device is connected to the reagent storage space 2 inside the cabinet body 1 through an air intake. A fixed protrusion 3 is provided at each of the four corners of the bottom of the cabinet body 1, and an exhaust groove 4 is provided at each of the four corners of the top of the cabinet body 1. An exhaust pipe 5 connects at least one fixed protrusion 3 to its corresponding exhaust groove 4. The exhaust device is connected to the exhaust pipe 5 through an exhaust port. The top of the exhaust pipe 5 has a unidirectional exhaust valve that allows only one-way exhaust. Valve 6 is connected to the vent hole 7 through the exhaust groove 4, allowing gas to exit only through the vent hole of the exhaust groove 4. Thus, the exhaust groove 4 can effectively expel acidic or alkaline gases from the cabinet 1. The bottom of the exhaust pipe 5 is connected to the vent hole 7 through the fixed protrusion 3 via a one-way valve 6 that allows only one-way air intake, ensuring gas can only enter the vent hole 7 of the fixed protrusion 3. The fixed protrusion 3 can be sealed and engaged within the adjacent exhaust groove 4. Both the fixed protrusion 3 and the inner walls of the vent holes of the exhaust groove 4 are provided with anti-corrosion conical films 8. The anti-corrosion conical films 8 of the exhaust groove 4 are connected to the exhaust... A short-circuit rubber sealing ring 9 is provided between the inner walls of the air groove 4 to provide a sealing effect when the fixed protrusion 3 is embedded in the air groove 4. The fixed protrusion 3 supports the cabinet 1 when it is in contact with the ground. When multiple storage unit cabinets 100 are stacked, the upper cabinet 1 is placed on the lower cabinet 1, and the fixed protrusion 3 can be embedded in the air groove 4 of the adjacent cabinet 1 below it, which achieves a stable stacking effect. The top of the air groove 4 can be connected to an external exhaust pipe, and the exhaust groove 4 can also allow the exhaust gas to pass through the embedded fixed protrusion 3. The air vent 7 is discharged into the exhaust pipe 5 of the top cabinet 1, and then the gas is discharged through the exhaust groove 4 in the top cabinet 1. In addition to exhausting the gas individually, it also serves as a gas transition and connection. While physically realizing the stacking of cabinets, it can make the exhaust continuous, without the need for each cabinet to exhaust individually. This means that no matter how many cabinets are stacked, only one exhaust port is needed. Therefore, when multiple storage unit cabinets are stacked, an exhaust pipe only needs to be connected to the exhaust groove 4 of the top storage unit cabinet 100 to realize the exhaust of all storage unit cabinets 100.

[0034] More preferably, the exhaust device includes a negative pressure partition and a purification partition. The bottom of the purification partition is connected to the reagent storage space 2 through a purification air intake port, and the top of the purification partition is connected to the negative pressure partition through a negative pressure air intake port 10. The negative pressure partition is connected to the exhaust pipe 5 through an exhaust port. The exhaust port is a negative pressure exhaust port 11. Under the action of the negative pressure partition, the gas in the cabinet 1 is drawn into the purification partition for filtration and then discharged from the cabinet 1. The purification partition includes an independently configured acidic filter layer 12 and an alkaline filter layer 13, which are not connected. The purification air intake includes an acidic air intake 14 and an alkaline air intake 15. The acidic filter layer 12 is connected to the reagent storage space 2 through the acidic air intake 14, and the alkaline filter layer 13 is connected to the reagent storage space 2 through the alkaline air intake 15. The negative pressure partition includes a first negative pressure device 16 and a second negative pressure device 17. The acidic filter layer 12 is connected to the first negative pressure device 16 through its corresponding negative pressure air intake 10, and the alkaline filter layer 13 is connected to the second negative pressure device 17 through its corresponding negative pressure air intake 10. Two fixed protrusions 3 are located near the exhaust device and are respectively positioned vertically. Each of the corresponding exhaust grooves 4 is provided with an exhaust pipe 5. The first negative pressure device 16 is connected to one of the exhaust pipes 5 through the exhaust port, and the second negative pressure device 17 is connected to the other exhaust pipe 5 through the exhaust port. An electric control valve is provided at the negative pressure intake port 10. The acid gas and alkaline gas exhaust are independent and there is no situation where they are turned on at the same time. The acid exhaust device and alkaline exhaust device are turned on separately according to the acidity or alkalinity of the reagent. The filtered gas is discharged into the exhaust pipe 5, and the exhaust pipe 5 will discharge the gas through the exhaust groove 4. It is also possible that the gas in the exhaust pipe 5 and the gas entering through the fixed protrusion 3 are discharged together through the exhaust groove 4 or discharged into the fixed protrusion 3 of the upper cabinet 1.

[0035] Example 2

[0036] This embodiment adds control functions to the first embodiment, enabling the storage combination cabinet to perform more adaptable functions, such as... Figure 6 and Figure 7 As shown, the storage unit cabinet also includes at least one control panel 18; the control panel 18 is a detachable and movable control panel, which can be installed on the cabinet door 19 on the side of the storage unit cabinet away from the exhaust device for easy operation. The control panel 18 is mainly used for functions such as reagent storage and retrieval and input and storage of user information in human-computer interaction; the cabinet door 19 is provided with a handle 20 for easy manual opening of the cabinet door 19.

[0037] The control panel 18 can be set on the cabinet 1 for easy operation according to the height of the storage unit cabinet 100. There are a large number of storage unit cabinets 100, which are stacked vertically and extended longitudinally. Depending on the frequency of use of the storage combination cabinet, multiple control panels 18 can be added and set on the storage unit cabinet.

[0038] The storage unit cabinets 100 can exchange information with each other, including wired and wireless transmission. For example, wired transmission utilizes multiple data transmission interfaces 21 and power interfaces 22 located on the rear of the storage unit cabinet, as well as multiple power supply interfaces 23. The data transmission interfaces 21 can connect multiple storage unit cabinets 100 via wired network data transmission. The power interfaces 22 can be connected to a 12V / 24V power supply individually, or they can be powered through the power supply interfaces 23 of adjacent cabinets 1. Simultaneously, the control panel 18 can also directly control the storage unit cabinets 100 via wired and wireless methods, thereby indirectly controlling all storage unit cabinets 100. This eliminates the need for a separate control module for each cabinet to control all storage unit cabinets.

[0039] The storage unit cabinet 100 is equipped with an electronic lock, which is controlled by a control panel 18. The electronic lock can be either a passive or active lock. Passive locks can be opened using, for example, NFC, and an NFC panel 24 can be installed on the control panel. Active locks can be opened using Bluetooth, which can be powered by a separate battery. An additional advantage of separate power supply is that it can detect the open or closed status of the door.

[0040] The main reason for using control panel 18 is that operators need to wear full protective clothing during the storage and retrieval of special reagents used in special experiments. It is inconvenient to operate a mobile phone while wearing protective clothing, so it is necessary to operate through control panel.

[0041] Example 3

[0042] The storage combination cabinet in Embodiment 1 mainly achieves three-dimensional extension and combination of storage unit cabinets through structural improvement. Embodiment 2 adds control function on the basis of Embodiment 1. The main difference between Embodiment 3 and Embodiment 2 is that the control terminal is changed to a mobile control terminal, which makes the operation more convenient.

[0043] The front door of the storage unit cabinet 100 is equipped with an electronic lock, controlled by a mobile phone terminal. The mobile terminal has two functions: first, it records reagent storage and retrieval information and user details; second, after recording the information, it unlocks the electronic lock via the phone's NFC or Bluetooth function. The main advantages of using a mobile terminal for control are twofold: first, it reduces the cost of equipping the storage unit cabinet with a control panel; second, when there are many people retrieving and returning reagents, the mobile terminal allows for simultaneous operation and retrieval by a large number of people, eliminating the need to queue at a specific control panel and improving the efficiency of reagent retrieval and return.

[0044] Electronic locks include passive locks and active locks. Passive locks can be opened using, for example, NFC. The NFC panel 24 can be set on the front of the storage unit cabinet 100, so that it can be used in scenarios without power. Active locks can be opened using Bluetooth. Bluetooth can be powered by a separate battery. An additional advantage of separate power supply is that it can detect the opening and closing status of the door.
