Abstract
The utility model provides a fixing device for a pulse tube of a cloth bag box, which consists of a pressing plate, a non-female screw rod, a connecting bolt and a fixing nut; connecting all the pulse tubes except the pulse tubes on the two sides in the cloth bag box to the edge of the box body of the cloth bag box by using non-female screws respectively; bolt holes are arranged on two sides of the L-shaped pressing plate, one surface of the L-shaped pressing plate is attached to the end head of the pulse tube, the other surface of the L-shaped pressing plate is buckled on the pulse tube, a screw head without a female screw is pressed below the pressing plate, and two sides of the pressing plate are fixed on the edge of the box body of the cloth bag box through connecting bolts and fixing nuts. The utility model discloses multiplicable pulse tube fixed strength avoids droing of pulse tube, as long as lift clamp plate both sides connecting bolt off during the dismantlement, will not have female screw rod directly extract can, greatly accelerate pulse tube dismouting speed, improve the operating efficiency of changing the sack.
Description
Technical Field
The utility model belongs to ironmaking mechanical equipment field especially relates to a sack case pulse tube fixing device.
Background
The coal powder bag box is an important fire-proof part in a coal powder area, the coal powder and various gases are filled in the bag box, and once the powder is accumulated on the bag or the local part, a fire accident is easily caused under the condition that the oxygen content exceeds the standard. Each bag box has 16 small boxes, 7 pulse tubes are arranged in each small box, 14 nozzles are arranged at the lower part of each pulse tube, each nozzle corresponds to 1 bag, and under the action of nitrogen pulse, the nozzles vibrate the coal powder adsorbed on the bags to the bottom of the bag box. Each pulse tube is fixed on a box body cross beam of the cloth bag box by adopting an independent bolt and is corroded by internal gas and water, the fixing bolt is corroded, part of bolts are loosened under the vibration of nitrogen pulse, and the pulse tube falls off. In addition, due to corrosion, the pulse tube is difficult to disassemble, and the work efficiency of replacing the cloth bag is influenced. Once the pulse tube falls off, the accumulated powder adsorbed on the cloth bag cannot fall to the bottom of the cloth bag box, and the accumulated powder is easy to spontaneously combust under the condition that the oxygen content exceeds the standard, so that the cloth bag in the whole cloth bag box is burnt.
Disclosure of Invention
The utility model provides a can improve pulse tube fixed strength, the dismouting of the pulse tube of being convenient for avoids the pulse tube to drop, improves the sack case pulse tube fixing device who changes sack operating efficiency.
Therefore, the utility model discloses the technical solution who takes does:
a fixing device for a pulse tube of a cloth bag box comprises a pressing plate, a non-female screw, a connecting bolt and a fixing nut; drilling a hole at one end of each pulse tube, and connecting all the pulse tubes except the first pulse tube and the last pulse tube positioned at two sides in the cloth bag box to a beam of the box body of the cloth bag box by using a nut-free screw rod respectively; the section of the pressing plate is L-shaped, bolt holes are formed in the positions, corresponding to the drilling holes of the first pulse tube and the last pulse tube, of the two sides of the pressing plate, one face of the L-shaped pressing plate is attached to the end head of the pulse tube, the other face of the L-shaped pressing plate is buckled on the pulse tube, the screw head without a female screw is pressed below the pressing plate, and the two sides of the pressing plate are fixed on a box body cross beam of the cloth bag box through connecting bolts and fixing nuts.
And a spring pad is arranged on a connecting bolt between the fixing nut and the box body cross beam of the cloth bag box.
The utility model has the advantages that:
the utility model discloses an it is whole fixed, increased pulse tube fixed strength, avoid droing of pulse tube, as long as dismantle 1 st and last when dismantling simultaneously, with the middle female screw rod of nothing directly extract can for pulse tube's dismouting speed has improved the operating efficiency of changing the sack.
Drawings
Fig. 1 is a schematic view of a fixing device for 7 pulse tubes in a cloth bag box.
In the figure: connecting bolt 1, clamp plate 2, sack case 3, no female screw 4, pulse tube 5.
Detailed Description
As shown in fig. 1, the fixing device for a bag box pulse tube of the present invention is composed of a connecting bolt 1, a pressing plate 2, a non-female screw rod 4 and a fixing nut. Drilling holes at the upper ends of the pulse tubes 5, and respectively connecting the other 5 pulse tubes 5 except the first pulse tube 5 and the last pulse tube 5 positioned at two sides in the cloth bag box 3 to a box body cross beam of the cloth bag box 3 by using nut-free screws 4, wherein nuts are not used on the nut-free screws 4. The section of the pressing plate 2 is L-shaped and is made of angle steel, bolt holes are formed in the positions, corresponding to the drilling holes of the first pulse tube 5 and the last pulse tube 5, of the two sides of the pressing plate 2, one surface of the pressing plate 2 is attached to the end of the pulse tube 5, the other surface of the pressing plate is buckled on the pulse tube 5, the screw head without the female screw rod 4 is pressed below the pressing plate 2, and the two sides of the pressing plate 2 are fixed on a box body cross beam of the cloth bag box 3 through the connecting bolts 1 and the fixing nuts. In order to increase the shockproof effect, a spring pad is arranged on the connecting bolt 1 between the fixing nut and the box body cross beam of the cloth bag box 3.
