Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dust prevention for loading chutes, and particularly relates to a dust prevention device for loading chutes. Background Technology
[0002] Port loading chutes are key pieces of equipment used to efficiently transfer bulk cargo (such as coal, ore, and grain) from port storage facilities or ships to railway freight cars. The design and operation of these chutes are crucial for improving port loading and unloading efficiency, reducing cargo loss, and ensuring safety.
[0003] Currently, due to the fine particles of bulk cargo such as ore transported at ore terminals, and the fact that they are easily broken during loading and unloading, a large amount of dust is generated. This dust is easily suspended in the air by the wind, forming dust storms. As a result, the dust environment generated by the loading chute at the ore terminal has a significant impact on the air quality of the surrounding area and also seriously affects the working environment of the staff. Utility Model Content
[0004] In view of this, the present invention aims to propose a dust prevention device for loading chutes, in order to solve the problem that bulk cargo such as ore in ore terminal transportation has fine particles and is easily broken during loading and unloading, generating a large amount of dust. The dust is easily suspended in the air under the action of wind, forming dust, which causes the dust environment generated by the loading chutes of ore terminals to have a significant impact on the air quality of the surrounding area and seriously affects the working environment of the staff.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0006] This utility model provides a dust prevention device for a loading chute. The dust prevention device is located at the bottom of the overall loading chute and includes a loading chute body, a water tank, a water pump, and a liquid level sensor. The loading chute body and the water tank are connected through the water pump, and the water pump is connected to the liquid level sensor. A first loading chute section, a second loading chute section, a third loading chute section, and a fourth loading chute section are sequentially arranged in the loading chute body. The first loading chute section, the second loading chute section, and the third loading chute section are installed at an angle downwards. The upwardly bent portion of the upper part of the first loading chute section is connected to the actual loading chute section. The downwardly bent portion of the third loading chute section is connected to the third loading chute section. The opening of the third loading chute section is vertically downwards and faces the loading vehicle in operation.
[0007] Furthermore, the first loading chute section has a first water tank connecting pipe and a second water tank connecting pipe, both of which are connected to the water tank via a water pump. Two first loading chute section fixing frames are symmetrically arranged at the bottom of the first loading chute section with respect to its centerline. Each first loading chute section fixing frame includes a first fixing plate and a second fixing plate. Three second fixing plates are vertically welded to the first fixing plate. The second fixing plates are welded to the bottommost end face of the first loading chute section, and the first fixing plate is welded to the loading chute fixing frame.
[0008] Furthermore, the second loading chute section is bolted to the first loading chute section. A second loading chute section fixing frame is welded to the bottom end face of the second loading chute section. The mounting plate at the bottom end of the second loading chute section is symmetrically fixed with respect to the centerline of the first inclined guide plate and the second inclined guide plate. The upper part of the first inclined guide plate is welded with two triangular mounting plates, and a triangular support plate is provided in the middle of the two triangular mounting plates for support. The bottom openings of the first inclined guide plate and the second inclined guide plate face the third loading chute section. The second loading chute section fixing frame is welded to the loading chute fixing frame.
[0009] Furthermore, a diversion angle steel is welded to the center of the interior of the third loading chute section. A third loading chute section fixing frame is welded to the front and rear of the third loading chute section. The second loading chute section fixing frame includes a fifth fixing plate and a fourth fixing plate. Three fifth fixing plates are evenly welded to the upper part of the fourth fixing plate. The fifth fixing plates are welded to the loading chute fixing frame.
[0010] Furthermore, a third fixing plate and a sixth fixing plate are welded onto the fourth loading chute section. The lower surfaces of the third fixing plate and the sixth fixing plate are welded together, and the third fixing plate is welded to the loading chute fixing frame.
[0011] Compared to existing technologies, the dust suppression device for loading chutes described in this invention has the following advantages: By installing a water tank, a water pump, and a level sensor at the bottom of the loading chute, the device effectively suppresses dust generated during the loading process by spraying water. Water is pumped from the water tank and sprayed onto the inside of the loading chute or onto the materials, thereby reducing dust emissions, improving the working environment, and protecting worker health. The sequential arrangement of the first to fourth loading chute sections within the main body of the loading chute, and the connection method between these sections, not only ensures that materials can smoothly slide from a height onto the loading vehicle, but also helps control and reduce the impact and dust generated during the material's descent. The level sensor accurately detects the liquid level, preventing overflow accidents caused by excessively high liquid levels, and also prevents the water pump from running dry, thus protecting the pump and helping to reduce operating costs.
