The lock box 6 is fixed on the outer wall of the container shell 2, and a gear meshed with the rack 5-1 on the inner side of the lock rod 5 is installed in the lock box 6.
The "container" described in the present embodiment may be referred to as a "tub", "box", or "box" depending on the shape of the final product, and it is a term of any kind that has a function of closing the container, and has structures of a container lid, a container case, and a container bottom, a reinforcing rib, a lock lever, and a lock case, for example: if the "container" is formed in a barrel shape, the container lid, the container shell and the container bottom may be referred to as a barrel lid, a barrel body and a barrel bottom, respectively.
According to the container for storing and transporting the industrial hazardous wastes, which is provided by the embodiment of the invention, the metal material is used for manufacturing the container shell, and the reinforcing ribs are added, so that the container can still ensure enough structural strength after a large amount of chemical hazardous wastes are contained in the container, the container can be reused, and the average cost of each use can be reduced after the metal container is reused for many times although the manufacturing cost of the metal container is higher than that of disposable containers such as plastic barrels, woven bags and the like; adopt locking lever and lock box to guarantee that the lid can be fixed a position and covered tightly by the accuracy, adopt the superimposed design of double containment pad in lid department simultaneously for the container lid can be sealed through self gravity completion, has realized the sealed storage of danger wastes material in the container. And because the container lid accomplishes the sealing through self gravity, therefore when a plurality of containers are piled up, the container that stacks on the top can exert bigger weight to the container that presses in the below to further improve and transfer the leakproofness of container, in the environment that a plurality of containers concentrate a large amount of stacks, can further improve the security on the contrary.
The container shell is made of metal materials, such as steel plates, in a mechanical bending mode, and the container shell can be formed only through one welding line, so that the purpose of preventing open fire of the container is achieved, and the processing cost is reduced as much as possible.
Specifically, the reinforcing ribs 4 are metal strips 4-2 welded to the outer wall of the container shell 2, and the metal strips 4-2 welded to the outer wall of the container shell 2 are interwoven into a grid shape.
Preferably, four outer walls enclosing the vessel shell 2 are formed by mechanically bending a metal plate. And as shown in fig. 2, in each outer wall, a reinforcing vertical rib 4-1 is mechanically bent at every prescribed distance.
Taking the container as a barrel shape and the metal plate as an example, the container shell of the embodiment can be realized by the following steps:
through the steel sheet of mechanically bending, roll over three right-angle sides and form four outer walls of vessel shell 2 to through welded connection fourth right-angle side. Through mechanical bending, every 200mm in each outer wall, a reinforcing vertical rib 4-1 with the width and the height of 40mm x 40mm is bent. The barrel body is a whole steel plate, a mechanical bending technology is adopted, three right-angle edges are folded to form four sides of the whole barrel body, and the other right-angle edge is connected through welding, so that the strength and the pressure resistance are improved, and the deformation is prevented.
The reinforcing vertical ribs 4-1 are formed by bending, extra welding processing is not needed again, and the reinforcing vertical ribs can be directly formed on a mechanical bending machine in one step, so that the production cost is further reduced.
Specifically, as shown in fig. 3, the edge of the container cover 1 is bent downward to form a container cover flange 1-2. The width of the upper layer of sealing gasket 1-1 is consistent with the width of the folded edge protrusion of the container shell 2, and the width of the upper layer of sealing gasket 1-1 is larger than that of the lower layer of sealing gasket 2-1.
Because the sealing is carried out by vertically superposing two layers of sealing gaskets, the upper layer of sealing gasket 1-1 is glued with the bottom of the container cover, and the lower layer of sealing gasket 2-1 is arranged in an outer edge groove of an opening at the upper part of the container shell. The four edges of the container cover 1 are bent downwards by using a bending machine to form container cover folding edges 1-2, the width of the upper layer sealing gasket 1-1 is consistent with the protruding width of the container shell folding edges, and the width of the upper layer sealing gasket 1-1 is larger than that of the lower layer sealing gasket 2-1. The outer edge of the container shell 2 is turned over through a flanging machine and is further welded into a trapezoidal groove, the upper portion of the groove is narrow, the lower portion of the groove is wide, the lower layer of sealing gasket 2-1 is pressed into the groove through mechanical equipment, and the sealing gasket slightly protrudes out of an opening in the upper portion of the container shell. The problem that the cover is damaged due to dislocation of the container cover caused by deviation can be effectively solved by the fact that the width of the upper layer sealing gasket 1-1 is larger than that of the lower layer sealing gasket 2-1, and the unmanned AGV forklift is convenient to fork and take. The bottom of the container cover 1 is designed to be convex inwards, so that the AGV intelligent system can be assisted to move the container cover to the container shell, and the auxiliary positioning effect is achieved.
The container shell 2 is designed to be a trapezoid groove, the upper portion of the groove is narrow, the lower portion of the groove is wide, the stress area of the bottom of the sealing gasket in the groove is increased in the process that the container cover is compacted and sealed, the stress deformation of the sealing gasket is uniform, and good sealing performance of the sealing gasket is guaranteed.
And the maximum height of a container cover folding edge 1-2 formed by bending the edge of the container cover 1 downwards is greater than the extending length of the lock rod 5. When the container cover 1 is placed on the ground, the stability of the four lock rods 5 at the bottom of the cover is poor and the stress is uneven, so that the lock rods 5 at the bottom of the cover are bent and broken, and the four edges of the container cover adopt the design of container cover folding edges 1-2, the folding length is slightly greater than the length of the lock rods 5, so that the lock rods 5 can be protected and stacked. And the sealing gasket on the top of the container cover 1 can play a certain role of buffering when the containers are stacked.
The lock rod is vertically arranged on the bottom surface of the container cover, and the lock box is arranged on the side wall of the container shell.
