Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for belt conveyors, in particular to a device for reducing the air volume at an inlet of a belt conveyor. Background Art

[0002] Belt conveyors are widely used in conveying and production lines in industries such as cement, mining, metallurgy, chemicals, foundry, and building materials, as well as in hydropower station construction sites and ports. They transport both bulk materials and finished goods and are essential equipment for sand and gravel production lines. Belt conveyors use a weighing scale to determine the weight of material on the belt. A digital speed sensor mounted on the rear of the conveyor continuously measures the feeder's speed. The speed and weight signals are fed into the feeder controller, where a microprocessor processes and displays the accumulated and instantaneous flow rate. This flow rate is compared with the set flow rate, and the control instrument outputs a signal to control the belt conveyor, thus achieving quantitative feeding.

[0003] In current use, belt conveyors are mostly installed in open-air environments and in high-altitude mountainous areas for the transportation of limestone. In winter, the direction of the wind is adjusted from east to west. In the mountains where the belt system is built, a large amount of wind blows from the outdoor to the indoor connection entrance of the belt system. Since the belt system transports ore, which contains particles and powder, all the dust on the belt is blown up, resulting in the underground chambers and corridors being full of blown dust, low visibility, and not only dust remaining on the ground, but also a lot of time is needed to clean the dust every day, which is not conducive to the health of the operators. Utility Model Content

[0004] The purpose of this utility model is to provide a device for reducing the inlet air volume of a belt conveyor, which has a reasonable structural design, low processing and manufacturing cost, convenient operation, safety and reliability, and easy installation, and can greatly reduce the amount of outdoor air entering the room, reduce the cleaning workload of the operator, and ensure the safety of the operator's operating environment.

[0005] The utility model discloses a device for reducing the air volume at the inlet of a belt conveyor, comprising a belt conveyor frame, a belt conveyor frame sealing cover fixedly mounted on the belt conveyor frame, a material guide trough fixedly mounted on the surface of the belt conveyor frame sealing cover, an air duct fixedly mounted on the surface of the material guide trough, and a ventilator fixedly mounted on the end of the air duct.

[0006] The provided belt conveyor rack can be installed at the connecting entrance between the outdoor and indoor areas of the belt conveyor. The installation is quick and easy. The belt conveyor rack can be sealed by the provided belt conveyor rack sealing cover with good sealing performance. The material guide trough and the air duct are fixedly installed on the surface of the belt conveyor rack sealing cover. The direction of the outdoor to indoor wind enters along the material guide trough and the air duct. Through the continuous operation of the provided ventilator, the direction of the outdoor to indoor wind is affected by the suction force of the ventilator, and the air volume can flow out upward along the air duct, which can greatly reduce the outdoor wind volume entering the room, avoiding the tedious labor of regular cleaning for on-site operators. Moreover, the less air volume entering, the less dust it contains, which is beneficial to the health of on-site operators and ensures the safety of the operating environment.

[0007] The side walls of the ventilator are fixedly installed with fixed vertical plates, there are four fixed vertical plates, every two fixed vertical plates are fixedly installed on the side walls of the ventilator, and are symmetrically arranged along the center line of the ventilator; the bottom end of the fixed vertical plate is fixedly installed with a duct fixing frame.

[0008] The set fixed vertical plate can firmly fix the ventilator on the wind tube fixing frame, which provides stable support, safety and reliability, and effectively prevents rollover. The set wind tube fixing frame can not only support and fix the ventilator, but also limit and fix the wind tube, and can firmly fix the wind tube on the wall outside the operating room.

[0009] The air duct fixing frame is fixedly installed on the outer wall surface of the air duct.

[0010] The outer wall of the air duct is fixedly mounted with support plates, and there are two support plates, which are symmetrically arranged along the center line of the air duct.

[0011] The bottom end of the support plate is fixedly mounted on the surface of the fixed frame.

[0012] The fixed frame includes a supporting plane, which is a rectangular structure. The bottom surface of the supporting plane is fixedly connected to support columns, and reinforcing ribs are fixedly connected between the support columns. The reinforcing ribs are arranged along the opposite sides of the support columns.

[0013] The support plate provided can play a role in fixing and supporting the wind duct, preventing the outdoor wind from being too strong, causing the wind duct to overturn or shift, which is not conducive to the safe and orderly operation of the entire device. One end of the support plate firmly fixes the wind duct to the wall outside the operating room, and the other end is fixed to the surface of the fixed frame. The fixed frame is supported by the ground and is placed firmly, which can play a good supporting role for the support plate. The fixation is safe and firm, which can effectively prevent the wind duct from overturning and shifting, and ensure the stable operation of the entire device.
