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 relative to 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 unloading platform conveyor line, 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 ore unloading platform includes a mounting mechanism, a top spray mechanism is provided on the top of the mounting mechanism;

[0006] The mounting mechanism includes a support frame;

[0007] The top spray mechanism includes 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 of the lower end of the connecting cavity, and 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 mounting 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 formed on the inner ring wall of the fixed ring. The conveying hole is communicated with the annular groove. An annular block is rotatably connected in the annular groove. A collection hole is formed on the annular block. An atomizing nozzle is fixedly connected to the inner ring wall of the annular block corresponding to the position of the collection hole. The atomizing nozzle is provided with four spray holes. Sealing rings are arranged on the upper surface and the lower surface of the annular block outside the annular groove. A motor is fixedly installed on the upper surface of the fixed ring. The output end of the motor is fixedly installed with a driving wheel through a coupling, and the driving wheel abuts against the sealing ring.

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

[0011] Specifically, both ends of the bolt extend outside 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 arranged downward, inclined to both sides, and toward the center position of the fixed ring.

[0013] Specifically, the inner wall of the feed hole is provided with threads.

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

[0015] Specifically, the collection hole is L-shaped. The short end of the L-shaped collection hole is communicated with the atomizing nozzle, and the long end of the L-shaped collection hole is communicated with the annular groove.

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

[0017] The first step: Install the installation frame at the ore unloading port position of the ore unloading platform through bolts. Hang the fixed ring below the ore unloading port of the ore unloading platform through the installation frame, while the fixing plate is located above the ore unloading port of the ore unloading platform.

[0018] The second step: Thread the joint of an external water pipe with the feed hole, and inject water into the connection cavity through the feed hole. The water in the connection cavity flows to the spray head and the conveying hole respectively, and is conveyed to the annular groove through the conveying hole.

[0019] The third step: Start the motor, the motor drives the annular block to rotate, and the annular block drives the collection hole to collect the water in the annular groove, injects water into the atomizing nozzle, and at the same time the annular block drives the atomizing nozzle to rotate.

[0020] Step 4: At this time, the spray head sprays water at the ore discharge opening of the ore unloading platform to wet the ore on the ore unloading platform. When the wet ore is unloaded downward, it will pass through the fixed ring. The atomizing nozzles move around the ore and spray water mist into the ore through three spray holes that tilt to both sides and towards the center position of the fixed ring. By spraying from multiple angles, the ore is prevented from blocking each other, so that the degree of wetting of the ore is increased and omissions are avoided. As the annular block rotates, the downward spray holes will form an annular cover, thus preventing some of the raised dust from spreading outwards.

[0021] Advantages of the present invention: When the spray dust removal device for the ore unloading platform of the present invention is in use, the device is installed on the ore unloading platform and suspended at the ore discharge opening of the ore unloading platform. Then, water is injected into the device and the motor is started. The spray head sprays water at the ore unloading platform position to wet the ore. The motor drives the atomizing nozzles to rotate, and the water mist sprayed from the spray holes in multiple directions will form a water mist cover. The multi-angle spraying ensures that the ore will not be blocked by other ores when falling and is wetted comprehensively. Moreover, the dust raised during the falling process will be isolated inside by the water mist cover and prevented from spreading. Brief Description of the Drawings

An annular groove 32 is formed on the inner ring wall of the fixed ring 31. The conveying hole 24 is communicated with the annular groove 32. An annular block 33 is rotatably connected in the annular groove 32. A collecting hole 34 is formed on the annular block 33. An atomizing nozzle 35 is fixedly connected to the inner ring wall of the annular block 33 corresponding to the position of the collecting hole 34. The atomizing nozzle 35 is provided with four spray holes. Sealing rings 36 are arranged on the upper surface and the lower surface of the annular block 33 outside the annular groove 32.
