Description

Technical Field

[0001] This utility model relates to a dust removal and sealing device for the lower hatch of a slag powder ship, belonging to the technical field of port loading and unloading equipment. Background Technology

[0002] Slag powder, short for granulated blast furnace slag powder, is a high-quality concrete admixture. Currently, a relatively complete slag powder industry chain has been formed in China, encompassing all aspects of slag powder production, processing, sales, and application. The quality and performance of slag powder products are continuously improving.

[0003] Slag powder products require transportation. Land transportation is primarily handled by slag powder tanker trucks, while sea transportation is mainly handled by slag powder ships. Loading is done by the tanker trucks transferring the slag powder through pipelines from the lower hatch of the ship. Before loading and after unloading, the ship's hold frequently needs dust removal and cleaning to prevent residues from other cargoes from affecting the purity of the slag powder or the purity and quality of subsequent cargo loading. Dust removal requires the use of vacuuming equipment to remove residual slag powder. To prevent spillage and damage to cargo and environmental pollution, the lower hatch of the slag powder ship needs to be sealed before dust removal. However, the hatch cover can only seal; it cannot perform dust removal. Currently, there is no dedicated dust removal and sealing device for the lower hatch of slag powder ships that can ensure a tight seal, shorten sealing time, and simultaneously perform dust removal. This issue urgently needs to be addressed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a sealing and dust removal device for the lower hatch of a slag powder ship. This sealing and dust removal device can effectively complete the sealing process of the lower hatch of the slag powder ship. After the dust collector pipe and elbow are connected, the dust collector can suck up dust, thereby adapting to different working conditions in the sealing and dust removal process, achieving the purpose of saving operating costs and improving production efficiency.

[0005] The technical solution to the above technical problem is:

[0006] A dust-collecting and sealing device for the lower hatch of a slag powder ship includes a sealing cover plate, an elbow, a T-shaped screw, and a pressure rod. The sealing cover plate is a square plate placed on the lower hatch of the slag powder ship. The sealing cover plate has elbow mounting holes on its surface. The elbow is a 90-degree bend, with its lower end connected to the elbow mounting holes on the sealing cover plate and its other end connected to a dust collector pipe. The sealing cover plate has screw holes at both ends on both sides, and two screws on each side of the sealing cover plate... T-shaped screws are inserted into the holes respectively. The pressure rod is a long rod with pressure rod screw holes at both ends. The two pressure rods are located below the lower hatch cover hinge plate and the lower hatch cover lock hole plate respectively. The lower ends of the two opposing T-shaped screws on both sides of the sealing cover plate are connected to the pressure rod screw holes at both ends of the two pressure rods respectively. The upper lock nut and the lower lock nut are screwed onto the two ends of the T-shaped screws respectively. The upper lock nut and the lower lock nut are locked to the upper plate surface of the sealing cover plate and the lower end surface of the pressure rod respectively.

[0007] The aforementioned dust removal and sealing device for the lower hatch of the slag powder ship comprises a sealing cover plate consisting of a flat plate and angle steel. Multiple angle steels form a square frame welded to the surface of the flat plate. One end of the flat plate of the sealing cover plate has a long strip-shaped notch, which is opposite to the lower hatch cover hinge plate. There are handles on both sides of the flat plate surface.

[0008] The aforementioned dust removal and sealing device for the lower hatch of the slag powder ship includes an elbow mounting ring fixed on the elbow mounting hole on the sealing cover plate. A flange surrounds the elbow at the lower end of the elbow, and the flange at the lower end of the elbow is placed on the elbow mounting ring. The screw holes on both sides of the sealing cover plate are elongated holes along the edge of the sealing cover plate. T-shaped screws are inserted into the elongated holes, and the T-shaped screws and the elongated holes are in a sliding fit.

[0009] The aforementioned dust removal and sealing device for the lower hatch of a slag powder ship includes an elbow fixing ring fitted at the lower end of the elbow. The elbow fixing ring is a circular ring with an inner diameter matching the diameter of the lower end of the elbow. Multiple elbow pressing holes, which are threaded holes, are evenly distributed around the circumference of the elbow fixing ring. The elbow fixing ring is fitted onto the lower end of the elbow and presses against the flange of the elbow. Elbow tightening bolts are tightened onto the surface of the elbow flange through the elbow pressing holes. Multiple fixing ring mounting screw holes are evenly distributed on the surface of the sealing cover plate on the outer circumference of the elbow mounting ring. Multiple fixing connecting plates are evenly distributed on the outer circumference of the elbow fixing ring, each with connecting holes that correspond to the multiple fixing ring mounting screw holes on the sealing cover plate. Fixing bolts are tightened through the connecting holes of the fixing connecting plates and the fixing ring mounting screw holes of the sealing cover plate.

[0010] The beneficial effects of this utility model are:

[0011] This utility model's sealing cover can seal the lower hatch of a slag powder ship, preventing dust from escaping during dust removal. The lower end of the elbow is connected to the sealing cover, and the upper end of the elbow is connected to the dust removal pipe, allowing dust inside the slag powder ship to be discharged through the elbow. The elbow fixing ring is pressed against the flange at the lower end of the elbow, ensuring a tight connection between the elbow and the elbow mounting ring, and allowing adjustment of the elbow's direction. The elbow fixing ring is fixedly connected to the sealing cover via a fixing connecting plate. Two pressure rods are respectively clamped below the lower hatch cover hinge plate and the lower hatch cover lock hole plate. Locking nuts are respectively locked to the upper surface of the sealing cover and the lower end surface of the pressure rods via the two ends of the T-shaped screws, thus fixing the sealing cover to the lower hatch of the slag powder ship.

[0012] This utility model has a simple structure and is easy to use. It can ensure that the lower hatch of the slag powder ship is tightly sealed, preventing dust from escaping from the lower hatch during dust removal. At the same time, it can shorten the sealing operation time and improve the sealing efficiency, effectively shortening the start-up time of the slag powder ship and increasing the port throughput.
