Description

Converter receiving port cover plate

Technical Field

The utility model belongs to the technical field of the converter material loading, concretely relates to converter receives material mouthful apron.

Background

The converter is the most common steelmaking equipment used at present due to the high production speed, high yield, high single-furnace yield, low cost and low investment. An important link in the steelmaking process is feeding, when scrap steel, ferroalloy, ore raw materials and the like are fed into a converter high-level auxiliary material bin and an alloy material bin, because the inlet of the material bin is in an open state, in the material distribution process, material dust is very serious, and the material dust not only pollutes the working environment and causes damage to the health of staff, but also pollutes the atmospheric environment.

Disclosure of Invention

In order to solve the technical problem, the utility model provides a converter receiving opening cover plate which can be automatically opened and closed by utilizing the balance principle of a lever.

The utility model provides a converter receiving opening apron, including installing the interior flip cover board that is used for covering the receiving opening at the receiving opening, the bottom of apron is provided with the right trapezoid recess, right trapezoid recess bottom surface is the circular arc tank bottom for with the cooperation of the apron installation face top of receiving opening, the vertical face of right trapezoid recess is located the receiving opening outside, and the inclined plane is located the receiving opening inboard, uses the right trapezoid recess to divide into outside apron and inboard apron as the border with the apron, outside apron bottom installation counter weight.

Furthermore, a plurality of hooks for hanging and loading the balance weight are arranged at the bottom of the outer side cover plate and are arranged at equal intervals.

Further, the angle of the inclined plane of the right-angled trapezoid groove at the bottom of the cover plate is less than 45 degrees.

Furthermore, a gap is reserved between the front end faces of the pair of cover plates.

Furthermore, the vertical surface and the inclined surface of the right trapezoid groove at the bottom of the cover plate are provided with buffer material layers.

Furthermore, the front end of the cover plate is provided with a maintenance inclined plane, and a hook groove is formed in the maintenance inclined plane.

Furthermore, a rotating shaft matched with the bottom of the arc groove is arranged on the upper bottom surface of the right-angle trapezoid groove in the bottom of the cover plate, and a bearing is arranged at the upper end of the cover plate mounting surface of the receiving port and matched with the rotating shaft.

The utility model discloses following beneficial effect has: 1. the utility model discloses a lever principle realizes receiving the automatic switching of material mouthful apron, has avoided the serious problem of raise dust that the cloth produced.

2. The utility model discloses a set up the right trapezoid recess bottom the apron, make the apron to the inboard upset of receiving the material mouth and spacing to the apron can not turn up.

3. The utility model discloses a terminal surface leaves the space before a pair of apron to set up the maintenance inclined plane at the apron front end, in case under the circumstances that the apron blocked, pull through external force and resume the normal position with the apron.

Drawings

FIG. 1 is a schematic view of a cover plate of a receiving port of a converter.

Detailed Description

In order to clearly illustrate the technical features of the present solution, the following explains the present solution by way of specific embodiments and with reference to the accompanying drawings.

Example 1: as shown in fig. 1, a converter receiving port cover plate comprises a pair of cover plates 1 installed at a receiving port and used for covering the receiving port and turning inwards, a gap is reserved between the front end surfaces of the cover plates 1, a maintenance inclined surface 3 is further arranged at the front end of the cover plate 1, and a hook groove is formed in the maintenance inclined surface 3 to prevent the cover plate 1 from being restored to the original position through external force traction under the condition that the cover plate 1 is clamped.

A right-angled trapezoid groove is formed in the bottom of the cover plate 1, and a right-angled surface of the right-angled trapezoid groove is located on the outer side of the receiving port to prevent the cover plate 1 from turning outwards; the bottom surface of the right-angle trapezoid groove is an arc groove bottom and is used for being matched with the top end of the mounting surface of the cover plate of the receiving port, and the mounting mode is simple in mounting and convenient to maintain; right trapezoid recess inclined plane 2 is located the material receiving mouth inboard, and the inclined plane angle is less than 45 degrees to guarantee that the angle of apron 1 revolute the axial upset is enough big, make the cloth go on smoothly, all be provided with the buffer material layer on the vertical face of apron bottom right trapezoid recess and the inclined plane, can prolong apron 1's live time.

Divide into outside apron and inboard apron with apron 1 with the right trapezoid recess as the boundary, outside apron bottom is provided with a plurality of couples that are used for carry counter weight 4, and a plurality of couples equidistant setting.

Example 2: the utility model provides a converter receiving opening apron, is different from embodiment 1, and the circular arc tank bottom of the right trapezoid recess in bottom of apron 1 is used for installing with the pivot cooperation, and the apron installation face upper end of receiving the material mouth sets up the bearing, and the pivot is connected with the bearing.

The utility model discloses the theory of operation: the converter receiving port cover plate is balanced by utilizing the balance principle of a lever, namely, the self weight of materials and the balance weight 4 are utilized to be mutually balanced. During the cloth, when the material fell into apron 1 inboard when lapping, along with the material increases, weight increase, and final weight is greater than when counter weight 4, apron 1 enstrophe, and the material gets into the material receiving port, and after the material reduces, weight reduces gradually and is less than when counter weight 4, turns over the board and gets back to horizontal position, seals the material receiving port, has avoided the serious problem of raise dust that the cloth produced.

It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are intended to be covered by the present invention.
