Description

Clamping groove type bin grate

Technical Field

The utility model belongs to the technical field of steel smelting equipment, concretely relates to draw-in groove formula feed bin double-edged fine-toothed comb.

Background

In the steel smelting process, materials such as coke and lump ore need to be conveyed to a storage bin through a belt conveyor for temporary storage so as to be used for a blast furnace and sintering, in the material discharging process, the materials are washed away, particularly, the materials are washed away seriously to wash away a grate at the top of the storage bin, and when the materials are seriously worn, the materials need to be subjected to fire-firing operation such as gas cutting, so that the labor intensity of workers is increased, during the fire-firing operation, if combustible materials such as coke powder or coke are placed in the storage bin, the potential safety hazards such as fire exist. And 1 hour is needed for replacing one bin grate, so that the labor intensity of workers is increased.

Disclosure of Invention

An object of the utility model is to provide a convenient change alleviates staff intensity of labour's draw-in groove formula feed bin double-edged fine-toothed comb.

The utility model provides a technical scheme that its technical problem adopted is: the clamping groove type bin grate comprises a square frame, the frame is formed by welding two longitudinal beams and two cross beams, a plurality of groups of clamping grooves are symmetrically arranged on the inner walls of the two longitudinal beams, each group of clamping grooves are oppositely arranged, and a grate plate is clamped in each group of clamping grooves.

Furthermore, a supporting plate is fixed on the lower portion of the inner wall of the longitudinal beam and located below the clamping groove and used for supporting the grate plate.

Specifically, the supporting plate is an angle steel and is welded on the inner wall of the longitudinal beam.

Specifically, the clamping grooves are welded on the longitudinal beam.

The utility model discloses following beneficial effect has: the utility model discloses a setting up the comb board that can dismantle, improving the efficiency of changing the feed bin comb, eliminating the great potential safety hazard that changes the feed bin comb and exist among the prior art, ensure staff's work safety, reduce staff's intensity of labour.

Drawings

Fig. 1 is a schematic view of the three-dimensional structure of the bin grate of the present invention.

Figure 2 is the plan view of the bin grate of the utility model.

In the figure, the device comprises a grate plate 1, a grate plate 2, clamping grooves 3, a frame 4, a supporting plate 5, longitudinal beams 6 and cross beams.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the clamping groove type bin grate comprises a square frame 3 formed by welding two longitudinal beams 5 and two cross beams 6, wherein a plurality of groups of clamping grooves 2 are symmetrically welded on the inner walls of the two longitudinal beams 5, each group of clamping grooves 2 is oppositely arranged, and a grate plate 1 is clamped in each group of clamping grooves 2. And a supporting plate 4 is fixed at the lower part of the inner wall of the longitudinal beam 5, and the supporting plate 4 is positioned below the clamping groove 2 and used for supporting the grid plate 1. The supporting plate 4 can be angle steel and is welded on the inner wall of the longitudinal beam 5.

When the bin grate is replaced, only the grate plate 1 which is seriously worn needs to be taken out upwards from the clamping groove 2, and then a new grate plate is replaced. Greatly shortening the replacement time of the bin grate.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Under the prerequisite that does not deviate from the design concept of the utility model, the ordinary person in the art should fall into the protection scope of the utility model to the various changes and improvements that the technical scheme of the utility model made.

The technology, shape and construction parts which are not described in detail in the present invention are all known technology.
