Description

A bottom structure and a hazardous solid waste storage container convenient for multi-directional fork

technical field

The invention relates to the technical field of chemical environmental protection, in particular to a bottom structure and a hazardous solid waste storage container which is convenient for multi-directional fork access.

Background technique

The progress of modern society and the development of human civilization after the industrial revolution are inseparable from the chemical industry. A wide variety of chemical products have become indispensable raw materials for people's production and life. And chemical safety and environmental protection have also become important issues in the chemical production industry. Hazardous waste treatment of various chemical enterprises is not only an important environment for chemical safety and environmental protection, but also the weakest link in chemical safety and environmental protection at present.

Due to the requirements of environmental protection, hazardous wastes cannot be discarded and discharged at will; and due to the requirements of safe production, hazardous wastes need to be properly handled. In actual production work, under the requirements of these two aspects, the result is that chemical enterprises first accumulate and store hazardous waste in a centralized manner, and then go to find disposal channels.

Although in other fields, such as the treatment of radioactive substances, highly safe sealed containers have been used, but the cost of radiation-proof sealed containers is extremely high, and it is difficult to apply to chemical environmental protection on a large scale. At present, most chemical companies store hazardous wastes in a centralized manner, often using disposable barrels (such as woven bags, plastic barrels, etc.) to store hazardous wastes. Since these containers are not airtight, they need to be stored in The barrels full of hazardous waste are stored in a closed room to meet the environmental protection requirements of the industrial park.

Once these disposable barrels with poor airtightness are piled up in a large amount or neglected to manage, the hazardous wastes in them are prone to secondary pollution or even explosion accidents due to natural reactions or static electricity, open flames and other reasons. Similar large-scale accidents have occurred in Tianjin, Jiangsu and other areas where the chemical industry is concentrated have occurred many times, causing huge casualties and economic losses.

When these containers are centrally stacked and managed, pallets or slots provided at the bottom of the containers are often used for fork picking. However, the design of the tray and the slot is only suitable for forking from a specific direction, and the forklift must be adjusted to a suitable side position to successfully fork the container to be moved. The side must be placed in the range that the forklift can pick up. On the other hand, it increases the work burden of the forklift. During the operation, it takes a lot of time and energy to adjust the forklift position, which reduces the work efficiency.

At the same time, the double-sealing gasket superimposed design is adopted at the lid, so that the container lid can be sealed by its own gravity, and the sealed storage of hazardous waste in the container is realized. And because the container cover is sealed by its own gravity, when multiple containers are stacked, the container stacked on top can exert a greater weight on the container pressed below, thereby further improving the airtightness of the lower container. In an environment where a large number of containers are centrally stacked, it can further improve security.

Among them, because metal materials, such as steel plates, are used to make the container shell by mechanical bending, the container shell can be formed with only one weld, which not only achieves the purpose of preventing the container from open fire, but also reduces the processing cost as much as possible. In a preferred solution, a steel plate with a thickness greater than or equal to 2 mm can be used. For example, a thin steel strip with a width of 1000 mm and a thickness of 2 mm is bent by mechanical bending to obtain a container shell.

Specifically, the reinforcing rib 4 is a metal strip 4-2 welded on the outer wall of the container shell 2, and the metal strips 4-2 welded on the outer wall of the container shell 2 are interwoven in a grid shape.

Taking the container as a barrel shape and the metal plate as a steel plate as an example, the container shell of this embodiment can be implemented in the following ways:

By mechanically bending the steel plate, three right-angled sides are folded to form the four outer walls of the container shell 2, and the fourth right-angled side is connected by welding. Through mechanical bending, a reinforcing vertical rib 4-1 with a width and a height of 40mm*40mm is folded every 200mm in each outer wall. The barrel body is made of a whole steel plate, and mechanical bending technology is adopted to fold out three right-angled sides to form the four sides of the barrel, and one right-angled side is connected by welding to increase strength, compressive resistance and prevent deformation.

Among them, the reinforcing vertical rib 4-1 is formed by bending, no additional welding process is required, and can be directly formed on a mechanical bending machine at one time, thereby further reducing the production cost.

Specifically, a lock box may be respectively installed on the four outer walls of the container shell 2;

A lock rod 5 is fixed at the bottom of each side of the container cover 1, and each lock rod 5 is matched with a lock box 6. Since each side is equipped with a lock box, the container cover 1 is installed to the container shell 2. easy to locate.
