Description

Technical Field

[0001] The invention relates to the technical field of spray dust reduction for an ore unloading platform, in particular to a spray dust removal device for an ore unloading platform and a dust removal method thereof. Background Art

[0002] The unloading platform is a device used for conveying and loading and unloading ore. During the transportation of ore on the unloading platform, the ore moves relatively with the conveyor belt, which reduces the fluctuation of the ore itself and reduces the dust raised by the ore. At the unloading port of the unloading platform, a large amount of dust will be raised as the ore collides with each other when it detaches and falls when it falls.

[0003] However, a spray dust removal device for an unloading platform with application number: CN202121694367.X only has a spray device on the top of the conveyor line of the unloading platform, and wets the ore during the transmission process. However, the wetting of the top alone cannot cover the ore, so that the mutual collision when the ore leaves the unloading platform and the fall when it falls will still raise a large amount of dust. Therefore, it is necessary to propose a spray dust removal device for an unloading platform and a dust removal method thereof. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a spray dust removal device for an ore unloading platform.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a spray dust removal device for an unloading platform comprises a mounting mechanism, and a top spray mechanism is arranged on the top of the mounting mechanism;

[0006] The mounting mechanism comprises a support frame;

[0007] The top spray mechanism comprises a fixed plate, a connecting cavity is formed on the fixed plate, a feed hole is formed through the connecting cavity, a conveying hole is formed through the hole wall at the lower end of the connecting cavity, a spray head is fixedly connected to the lower surface of the fixed plate, and the spray head is connected to the connecting cavity;

[0008] A spray dust removal mechanism is fixedly installed at the bottom of the installation mechanism;

[0009] The spray dust removal mechanism includes a fixed ring, which is fixedly installed at the lower end of the support frame, an annular groove is provided on the inner ring wall of the fixed ring, the conveying hole is connected to the annular groove, an annular block is rotatably connected in the annular groove, a collecting hole is provided on the annular block, an atomizing nozzle is fixedly connected to the inner ring wall of the annular block corresponding to the collecting hole position, the atomizing nozzle is provided with four spray holes, sealing rings are provided on the upper and lower surfaces of the annular block outside the annular groove, a motor is fixedly installed on the upper surface of the fixed ring, a driving wheel is fixedly installed on the output end of the motor through a coupling, and the driving wheel is against the sealing ring.

[0010] Specifically, the mounting mechanism includes a mounting frame, which is L-shaped and fixedly connected to a support frame. A threaded hole is formed through the mounting frame, and a bolt is threadedly connected in the threaded hole.

[0011] Specifically, both ends of the bolt extend out of the threaded hole, and one end of the bolt is fixedly connected with a hexagonal nut.

[0012] Specifically, the four spray holes of the atomizing nozzle are respectively directed downward, inclined toward both sides, and arranged toward the center of the fixing ring.

[0013] Specifically, a thread is arranged on the hole wall of the feed hole.

[0014] Specifically, the outer ring wall of the sealing ring abuts against the inner ring wall of the fixing ring.

[0015] Specifically, the collecting hole is arranged in an L shape, the L-shaped short end of the collecting hole is connected to the atomizing nozzle, and the L-shaped long end of the collecting hole is connected to the annular groove.

[0016] The dust removal method for the ore unloading platform also includes the following steps:

[0017] Step 1: Install the mounting frame at the unloading port of the unloading platform by means of bolts, suspend the fixing ring below the unloading port of the unloading platform by means of the mounting frame, and the fixing plate is located above the unloading port of the unloading platform;

[0018] Step 2: The joint of the external water pipe is threadedly connected to the feed hole, and water is injected into the connection cavity through the feed hole. The water flows to the sprinkler head and the delivery hole in the connection cavity, and is delivered to the annular groove through the delivery hole.

[0019] Step 3: Start the motor, the motor will drive the annular block to rotate, and the annular block will drive the collection hole to collect the water in the annular groove, and inject water into the atomizing nozzle, and the annular block will drive the atomizing nozzle to rotate;

[0020] Step 4: At this time, the sprinkler head sprays water to the unloading port of the unloading platform to wet the ore on the unloading platform. The wetted ore will pass through the fixed ring when unloading downwards, and the atomizing nozzle moves around the ore, and sprays water mist into the ore through three nozzles inclined to both sides and toward the center of the fixed ring. It avoids mutual blocking between ores at multiple angles, so that the degree of wetting of the ore is increased to avoid leakage, and the downward spray holes will form an annular cover as the annular block rotates, thereby preventing some of the raised dust from spreading outward.

[0021] Beneficial effects of the present invention: When the spray dust removal device for the unloading platform of the present invention is used, the equipment is installed on the unloading platform and hung at the unloading port of the unloading platform. Then water is injected into the equipment and the motor is started. The spray head sprays water toward the unloading platform and wets the ore. The motor drives the atomizing nozzle to rotate, and the water mist sprayed from the spray holes in multiple directions forms a water mist cover. The multi-angle spray prevents the ore from being blocked by other ores when falling and is fully wetted. The dust excited when falling will also be isolated inside by the water mist cover to avoid spreading. BRIEF DESCRIPTION OF THE DRAWINGS
