Detailed Description

The utility model is further described below with reference to the drawings.

As shown in figures 1-2, the dust removing device for the cement tank of the concrete mixing plant has the total weight of the tank body 8 of the cement tank of about 8 tons and the height of about 18m. Before transformation, a crane is used for hoisting the cement tank 8. The perpendicularity of the tank body is measured by using a level ruler, the tank body is guaranteed to be free from tilting, and then 4 feet of the tank body are welded and fixed. Here, we use carbon dioxide gas shielded welding. On one hand, the deformation of the carbon dioxide gas shielded welding is small, the crack resistance of the welding seam is high, and the welding seam is safer. On the other hand, the operation is simple, the production efficiency is high, and the welding cost is low.

Cutting the galvanized pipe by a cutter to a proper length, and then firstly welding the cut galvanized pipe on the ground (manufacturing a dust removing pipeline 9); and the welded galvanized pipe is hung to one side of the tank body by a crane and is vertically placed, and an operator climbs the tank body to the tank top through the tank body ladder to perform welding operation.

The top surface of the cement tank 8 is cut with round holes phi 50 by gas, a 0.5m long galvanized pipe (elbow) is welded with a phi 100 flange piece, one end of the welded galvanized pipe is directly inserted into the tank body, then welding and sealing are carried out, and one end of the welded flange piece is fastened and connected with a dust removal pipeline welded in advance through a 8.8-grade phi 24 outer hexagon bolt. If two cement tanks exist, the No. 1 tank and the No. 2 tank are connected through a tee joint.

For safety, 2.4m.times.2.4m guardrails made of phi 5 steel bars are welded on the top of each tank body. After the welding operation of the top of the tank body is finished, a dedusting pond of 1m 2m 1.5m is required to be poured near the tank body; one end of the dust removing pipeline 9 is connected with the elbow, and the other end of the dust removing pipeline 9 is placed in the dust removing pool filled with water, and when the dust removing pipeline is used, dust is discharged into the dust removing pool through the dust removing pipeline, so that the dust removing effect is achieved.
