Description

Technical Field

[0001] The utility model relates to the technical field of chemical drug storage, in particular to a chemical drug storage cabinet with a poisonous gas adsorption structure. Background Technique

[0002] Experimental equipment refers to the equipment used in experiments. Chemical drugs, as essential materials in the experimental process, are usually referred to as chemical reagents. Different chemical drugs have different characteristics. For poisonous chemical drugs, they are usually stored in sealed containers. At present, multiple chemical drugs are stored in a storage cabinet. When storing, a small amount of gas will overflow into the storage cabinet. To avoid the influence of the leaked poisonous gas on people, the poisonous gas is usually processed.

[0003] After retrieval, the utility model patent with the authorization announcement number of CN 220677872 U (hereinafter referred to as the comparative document D1) discloses a chemical drug storage cabinet with a poisonous gas adsorption structure. As the prior art, this device can pour the solvent for treating activated carbon into the treatment box, and then pour the activated carbon into the treatment box to make the solvent contact with the activated carbon, adsorb the impurities on the surface of the activated carbon, and separate the impurities from the activated carbon, so that the activated carbon can be regenerated for recycling, solving the problem that the activated carbon in the prior art needs to be replaced after use and it is not convenient to recycle the used activated carbon. However, the above operation process is relatively cumbersome. Each time the operation is performed, the cabinet door needs to be opened, which poses a risk of poisonous gas leakage. Or the operator needs to wear gas protection equipment, and the operation is not simple enough. Moreover, a treatment component is arranged on the lower side inside the storage cabinet body, and the treatment component occupies a large space in the cabinet body, resulting in a smaller space for storing chemical drugs in the cabinet body, affecting the storage capacity of the device and reducing the practicability of the device. Therefore, we design a chemical drug storage cabinet with a poisonous gas adsorption structure to solve the above technical problems. Content of the Utility Model

[0026] A top box 5 is fixedly provided on the top of the cabinet body 1. A vertical box 4 is connected to the rear side of the top box 5, and the bottom of the vertical box 4 is connected to the top of the treatment box 3. The top box 5 and the vertical box 4 are integrally formed. The vertical box 4 communicates the inside of the top box 5 with the inside of the treatment box 3. A fan frame 9 communicating with its inside is provided on the top of the top box 5. A fan 20 is provided inside the fan frame 9. A dust-proof net 10 is provided on the top of the fan frame 9. A cover door 11 is movably provided on one side surface of the top box 5. The setting of the cover door 11 facilitates placing activated carbon into the top box 5.

[0027] A plurality of ventilation holes 21 are provided on the inner bottom wall of the top box 5 and facing the fan 20. A vertical plate 22 adapted to it is slidably provided inside the top box 5. The number of the vertical plates 22 is two, and they are symmetrically distributed on the left and right sides of the ventilation holes 21. Two connecting rods 23 are fixedly provided between the two vertical plates 22, and the two connecting rods 23 are symmetrically distributed on the front and rear sides of the bottom of the fan 20.

[0030] Specifically, when the activated carbon needs to be processed during the use of the device, the fan 20 is turned off. Subsequently, the push block 15 is used to push the push rod 16 to insert into the top box 5, and then the two vertical plates 22 and the two connecting rods 23 are pushed to move leftward together. During the movement, the activated carbon located between the two vertical plates 22 is pushed by the vertical plates 22 to move together until the vertical plates 22 move into the vertical box 4. At this time, the activated carbon can fall downward through the vertical box 4 onto the filter plate 17 inside the processing box 3. Then, the pump body 7 is started, and the solvent in the liquid storage tank 2 is pumped into the processing box 3 through the infusion pipe 6. After the solvent is fully in contact with the activated carbon, the impurities on the surface of the activated carbon can be removed by the solvent, so that the adsorption effect of the activated carbon is restored. Subsequently, the valve is opened, and the solvent returns to the liquid storage tank 2. After the filter plate 17 is pulled outwards through the handle, the activated carbon is taken out. Then, the cover door 11 is opened to put the activated carbon back into the top box 5. At this time, under the elastic force of the spring 14, the vertical plate 22 has been reset, that is, the activated carbon is still located between the two vertical plates 22, which is convenient for repeating the above operation next time. When the device processes the activated carbon, there is no need to open the cabinet door, and it can be completed outside the cabinet body 1. The operation is simple and convenient, avoiding the risk of toxic gas leakage during the operation process. The staff does not need to wear gas protection equipment, greatly simplifying the operation process. In addition, since the relevant structures for processing the activated carbon are all arranged outside the cabinet body 1, the internal space of the cabinet body 1 can be fully utilized, improving the storage capacity of the cabinet body 1 and the practicability of the device.
