Description

Technical Field

[0001] The present application relates to a hazardous waste temporary storage cabinet with a liquid collection and temporary storage function. Background Art

[0002] Hazardous waste temporary storage cabinet refers to equipment used for the temporary storage and management of hazardous waste. Among hazardous wastes, liquid hazardous waste is a fairly common type. Since liquid hazardous waste itself has the characteristic of being easy to flow, it is necessary to consider its handling method for temporary storage cabinets that store liquid hazardous waste or may produce liquid hazardous waste. Now, the general way to deal with this situation is to set up an export trough. However, it should be noted that the storage capacity of the export trough is extremely limited, and generally it is impossible to set up relatively good protection, and harmful gases are very easy to be generated. Therefore, it is necessary to improve the structure of the existing export trough to adapt to the working conditions where liquid hazardous waste may be stored or liquid hazardous waste may be produced. Utility Model Content

[0003] To address the above-mentioned issues, the present application proposes a hazardous waste temporary storage cabinet with a liquid collection and temporary storage function, comprising a temporary storage box, a transversely arranged outlet slot at the bottom of the temporary storage box, a collection pool connected to the outlet slot on one side of the outlet slot, and an outlet pipe on the side of the collection pool. The outlet pipe extends through the wall of the temporary storage box, and a outlet control valve is provided on the outlet pipe. By providing interconnected outlet slots and collection pools, the present application greatly increases the liquid storage capacity, with the outlet slot serving as a drainage channel and the collection pool serving as a collection channel. Furthermore, after collection, combined with the function of a protective plate, steam overflow can be minimized to avoid contamination.

[0004] Preferably, a partition plate is provided between the outlet trough and the collection tank, a connecting pipe passing through the partition plate and connected to the collection tank is provided at the bottom of the outlet trough, and a connecting valve is provided on the connecting pipe.

[0005] Preferably, the collection pool includes a holding pool located at the top, a protective plate is arranged above the holding pool, and several temporary storage cylinders are connected and arranged below the holding pool. The bottom of the temporary storage cylinder is connected through a bottom connecting pipe, and the outlet pipe is connected to the temporary storage cylinder located on the outside.

[0006] Preferably, a lower inlet conduit is provided between the holding tank and the temporary storage cylinder. The lower inlet conduit is a tapered tube with a cross-sectional area that gradually decreases from the holding tank to the temporary storage cylinder. The present application utilizes a constricted design of the lower inlet conduit to effectively guide the flow while minimizing the generation of vapor from the liquid within the temporary storage cylinder and its overflow to the outside, thereby preventing contamination.

[0007] Preferably, a steel grating is provided on the upper portion of the guide chute.

[0008] Preferably, a door opening is provided on one side of the temporary storage box, with an opening door provided on the door opening. A transfer passage is provided on the inner side of the temporary storage box adjacent to the opening door, and a storage area is provided on the other side of the transfer passage, with the outlet trough provided below the storage area. In this application, a plurality of storage racks are generally provided in the storage area, and the carriers for hazardous waste are placed on these racks. In the event of overflow, the bottom of the temporary storage box is generally provided with a sloped outlet trough to prevent liquid from spilling.

[0009] Preferably, an explosion-proof observation window is provided on the opening door.

[0010] Preferably, a plurality of air inlets are provided on the temporary storage box on the other side of the open door, a plurality of explosion-proof exhaust ducts are provided on the temporary storage box on the other side of the air inlet, an explosion-proof exhaust fan is provided on the explosion-proof exhaust duct, and a protective guardrail is provided on the outside of the explosion-proof exhaust fan; the air inlet is provided at a lower middle position of the temporary storage box, and the explosion-proof exhaust duct is provided at an upper middle position of the temporary storage box.

[0011] Preferably, a plurality of hanging dry powder fire extinguishers and a plurality of explosion-proof lamps are provided on the inner side of the top of the temporary storage box.

[0012] This application can bring the following beneficial effects:

[0013] 1. This application sets up a connected outlet trough and a collection pool. The outlet trough plays a drainage role, and the collection pool plays an accumulation role, which greatly increases the liquid holding capacity. After collection, combined with the role of the protective plate, it can reduce steam overflow as much as possible to avoid pollution.

[0014] 2. The present application adopts a neck-type design of the lower inlet pipe, which can, on the one hand, play a better diversion role, and on the other hand, minimize the generation of steam from the liquid in the temporary storage cylinder and overflow to the outside to avoid pollution.

[0015] 3. This application generally sets up some holding racks in the storage area, and uses these racks to place hazardous waste carriers. When overflow occurs, the bottom of the temporary storage box is generally set with a sloped outlet trough to avoid liquid overflow. BRIEF DESCRIPTION OF THE DRAWINGS
