Description

Technical Field

[0001] The utility model belongs to the technical field of dolomite processing, and particularly relates to a conveyor belt structure for preventing dolomite from falling off. Background Art

[0002] Dolomite is mainly formed in crystalline limestone and magnesium-rich metamorphic rocks, and is also found in hydrothermal veins and cavities of carbonate minerals. It also occasionally appears in the cementing materials of various sedimentary rocks. Dolomite has a wide range of applications in the fields of building materials, glass, ceramics, refractory materials, chemical industry, environmental protection, energy conservation, agriculture, medicine, etc. It can also be used as basic refractory materials, flux for blast furnace ironmaking, and for producing calcium magnesium phosphate fertilizer, preparing magnesium sulfate, etc.

[0003] Generally, the processing of dolomite mainly includes steps such as crushing, grading, surface treatment or modification, etc. The crushing and grading of dolomite are generally carried out by dry methods. Commonly used crushing equipment includes jaw crushers, impact crushers, cone crushers, roll crushers, etc. Grading equipment includes screening machines, classifiers, etc. During the process of crushing and grading dolomite, a belt is usually used to transport dolomite. However, during the process of crushing dolomite, due to the action of mechanical force for operations such as crushing and grinding dolomite, the particles of dolomite will be refined and separated from the large-volume materials, forming a large number of fine particles suspended in the air, thus generating dust. If these dolomite dusts are not properly treated and controlled, they will cause harm to the physical health of operators. For example, it may cause respiratory diseases, etc. When reaching a certain concentration in a certain space and encountering a fire source, there will also be a risk of explosion. For processing equipment, the dust may enter key components of the equipment, such as bearings, motors, etc., affecting the normal operation and service life of the equipment. Therefore, when transporting dolomite, it is necessary to prevent the dolomite dust on the belt from falling off, and avoid the dolomite dust on the belt from falling on the transportation equipment and the transportation site.

The embodiments of the present utility model will be described below according to its overall structure.

[0026] Refer to Figure 1 and Figure 4 , a conveyor belt structure for preventing dolomite from falling, including an upper frame 1, a lower frame 2, and a conveyor belt 3 installed between the upper frame 1 and the lower frame 2. A falling prevention plate 4 is connected to the bottom of the lower frame 2. A dust collection mechanism 5 is connected to the upper frame 1. A guard plate 6 is connected to the outer sides of the lower frame 2 and the upper frame 1. The guard plate 6 abuts against the falling prevention plate 4. The dust collection mechanism 5 abuts against the top of the guard plate 6. The falling prevention plate 4, the dust collection mechanism 5, and the guard plate 6 wrap the conveyor belt 3.

[0027] Among them, a feeding mechanism 7 is provided at the feeding end of the conveyor belt 3. The feeding mechanism 7 includes a feeding hopper 71 and a baffle plate 72 connected inside the feeding hopper 71. The baffle plate 72 extends from below the feeding hopper 71 and can block the dolomite at the feeding end, so that the dolomite will not slide off the conveyor belt 3. The feeding hopper 71 is connected to the top of the upper frame 1, and the side end of the feeding hopper 71 is connected to the dust collection mechanism 5; a protective cover 8 is also provided at the feeding end of the conveyor belt 3. The protective cover 8 is connected to the lower frame 2 and the upper frame 1, and the bottom of the protective cover 8 abuts against the anti-falling plate 4.

[0028] Specifically, when the existing conveyor belt structure transports dolomite, usually a guide pipe is used to drop the dolomite from other equipment onto the conveyor belt 3. There is a certain distance between the guide pipe and the conveyor belt 3, and when the dolomite falls on the conveyor belt 3, dolomite powder will be scattered. At the same time, the conveyor belt 3 is in a moving state during operation, and the dolomite powder on the conveyor belt 3 also falls.

[0029] In the present utility model, a feeding hopper 71 is directly connected to the top of the upper frame 1, and a protective cover 8 is provided at the feeding end of the conveyor belt 3. The protective cover 8 can protect the feeding end of the conveyor belt 3 and cover the feeding end of the conveyor belt 3. The anti-falling plate 4 is detachably connected to the bottom of the lower frame 2, and at the feeding end of the conveyor belt 3, the end face of the anti-falling plate 4 exceeds the end face of the lower frame 2, so that after the side part of the protective cover 8 is connected to the lower frame 2 and the upper frame 1, its bottom can abut against the upper surface of the anti-falling plate 4, and then seal the end face of the conveyor belt 3. The dust collection mechanism 5 is connected to the top of the upper frame 1 to seal the upper part of the conveyor belt 3, while the anti-falling plate 4 seals the lower part of the conveyor belt 3. At the discharging end of the conveyor belt 3, a cloth bag is provided. The cloth bag seals the discharging end of the conveyor belt 3, and the dolomite falls into the collection equipment or the conveying equipment in the next stage from the cloth bag.

[0030] Specifically, a feeding port 710 is opened on the feeding hopper 71. The feeding port 710 can allow the dolomite to enter the feeding hopper 71 and then fall onto the conveyor belt 3. The baffle plate 72 inside the feeding hopper 71 extends from below the feeding hopper 71 and keeps a distance of 5 mm to 10 mm from the conveyor belt 3. When the dolomite falls from the feeding hopper 71 onto the conveyor belt 3, the baffle plate 72 can block the dolomite. Especially when the entire frame is inclined, that is, the feeding end of the conveyor belt 3 is at a low position and the discharging end of the conveyor belt 3 is at a high position, the dolomite is likely to fall out of the conveyor belt 3 at the feeding end, while the baffle can block the dolomite. Whether the conveyor belt 3 is horizontally arranged or inclined, it can prevent the dolomite from falling out of the conveyor belt 3 at the feeding end.
