Description
Technical Field
The utility model relates to a sintering equipment field especially relates to a sintering machine bellows adjusting valve.
Background
The air box regulating valve of the sintering machine is a valve positioned between an air box of the sintering machine and a large flue pipe insertion pipe, is used for controlling the air quantity and negative pressure of sintering waste gas in the air box, and consists of a valve box and turning plates arranged in the valve box, wherein the conventional valve box comprises two turning plates which are respectively arranged at the 1/3 part and the 2/3 part of the valve box through rotating shafts, and the turning plates rotate by a certain angle through rotating the rotating shafts during regulation so as to meet the production requirement. The main defects are as follows: the two sets of turning plates are respectively positioned at the positions of the valve boxes 1/3 and 2/3, so that the flow resistance of waste gas is increased, the sintering production capacity is reduced, and waste gas flows through the two sides of the turning plates, so that the gap is small, material blockage is easy to occur, and the production is directly influenced.
SUMMERY OF THE UTILITY MODEL
For overcoming the above-mentioned not enough that current valve box turns over the board existence, the utility model aims to solve the technical problem be: provides an air box regulating valve of a sintering machine, which can reduce the flow resistance of waste gas and is not easy to block materials.
The utility model provides a technical scheme that its technical problem adopted is:
the sintering machine air bellow regulating valve comprises a valve box and a regulating valve plate located in the valve box, wherein the regulating valve plate comprises a fixed baffle and a turning plate, the fixed baffle is fixed on the upper half part of the cross section of the valve box, the turning plate is located on the lower half part, and a rotating shaft of the turning plate abuts against the lower edge of the fixed baffle.
Further, the fixed baffle is fixed on the valve box through welding.
Furthermore, baffle reinforcing ribs are arranged in the middle of two sides of the fixed baffle.
Further, the distance from the rotating shaft of the turning plate to the lower edge of the fixed baffle is 3-5 mm.
Furthermore, turning plate reinforcing ribs are arranged in the middle of two sides of the turning plate.
Further, the flap and fixed stop are located at the lower part 1/3 of the valve box where the flap rotates.
The utility model has the advantages that: through demolising original upper portion plate turnover, only remain lower part plate turnover to change plate turnover into half fixed stop and half structural style who turns over the board, turn over the board through the control and open or partly, reach the production needs, this structural style reduces sintering waste gas flow resistance, and sintering ability improves, and the difficult putty of bellows.
Drawings
Fig. 1 is a schematic view of a conventional valve box structure.
Fig. 2 is a schematic structural diagram of the valve box of the present invention.
Marked in the figure as 1-valve box, 2-fixed baffle, 3-turning plate, 21-baffle reinforcing rib, 31-rotating shaft and 32-turning plate reinforcing rib.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, two sets of plate turnover devices are arranged in the existing valve box, and the plate turnover 3 is rotated by a certain angle by rotating the rotating shaft 31, so as to meet the production requirements. The main defects are as follows: the two sets of turning plates are respectively positioned at the positions of the valve boxes 1/3 and 2/3, so that the flow resistance of waste gas is increased, the sintering production capacity is reduced, and waste gas flows pass through the two sides of the turning plates, so that the gap is small, material blockage is easy to occur, and the production is directly influenced.
The structure after this application improves is shown in fig. 2, this sintering machine bellows governing valve, including valve box 1 with be located the valve plate of adjusting of valve box 1, the valve plate of adjusting includes fixed stop 2 and turns over board 3, fixed stop 2 is fixed in the first half of valve box 1 cross section, turn over board 3 and be located the lower half, the pivot 31 that turns over board 3 supports and leans on the lower edge at fixed stop 2. This application has cancelled original two sets of plate turnover, changes into one set to adopt half fixed stop to add half structural style who turns over the board, turn over board 3 through the control and open or part, it is required to reach production, and this structural style reduces sintering waste gas flow resistance, and the sintering ability improves, and bellows is difficult for the putty.
In order to improve the stability of the installation of the device, the fixed baffle 2 is preferably fixed to the valve housing 1 by welding. Because the area of fixed stop 2 is big, and the texture is thinner for improve stability the middle part of fixed stop 2's both sides is equipped with baffle strengthening rib 21.
When the turning plate 3 is installed, the clearance between the turning plate 3 and the fixed baffle 2 should be reduced as much as possible, and meanwhile, the rotation interference should be avoided, so the rotating shaft 31 of the turning plate 3 is preferably 3-5mm away from the lower edge of the fixed baffle 2. In order to ensure the structural strength of the turning plate 3, the middle parts of the two sides of the turning plate 3 are provided with turning plate reinforcing ribs 32.
When the installation positions of the turning plate 3 and the fixed baffle 2 are determined, in order to reduce the workload of change, the turning plate device at the middle upper part of the original valve box 1 is preferably cancelled, the turning plate device at the lower part is reserved, namely the turning plate 3 and the fixed baffle 2 are positioned at the 1/3 position at the lower part of the valve box 1, the turning plate 3 at the upper half part is cut off, the fixed baffle 2 is changed into the turning plate 3, the turning plate 3 rotates at the lower half side of the valve box 1, the ventilation requirement is ensured, and the valve box is not easy to block by materials.
