Description

Technical Field

[0001] The utility model belongs to the technical field of energy-saving control of conveyors, and in particular relates to a device for reducing the efficiency of a long-distance belt conveyor. Background Art

[0002] The driving force of the belt conveyor is composed of the main resistance and the additional resistance. The driving circumferential force calculation formula is: Fu = FH + FN + FS1 + FS2 + FSt = fLg [qRO + qRU + (2qB + qG) cosδ] + FN + FS1 + FS2 + FSt,

[0003] Through the above formula, it is found that there are many factors that affect the driving force. However, for a single belt conveyor under the same working conditions, the gravitational acceleration g, the conveyor length L, the average inclination angle δ of the conveyor in the running direction, and the conveyor belt speed are fixed.

[0004] The key factors that determine the driving force are as follows:

[0005] qG—The mass of the conveyed material per meter. The material weight is determined by the capacity of the transport system and cannot be changed.

[0006] qB—the mass of the conveyor belt per meter. The weight of the conveyor belt is the main issue studied by the conveyor belt manufacturer.

[0007] qRO, qRU—the mass of the rotating part of the roller, which is studied by the roller manufacturer;

[0008] Therefore, more influencing factors lie in the friction coefficient f. If you need to reduce the power of the belt conveyor, you need to reduce the friction coefficient f. However, in belt conveyor transportation, another key link is also related to the friction coefficient f, that is, slipping. In the Euler formula that meets the no-slip condition, the smaller the friction coefficient f, the easier it is to slip, which forms a contradiction with the need to reduce the friction coefficient f to reduce the power.

[0009] Therefore, it is urgent to design a device for reducing the power of the belt conveyor, which can reduce the power of the belt conveyor while ensuring that slipping does not occur. Utility Model Content

[0010] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a device for reducing the efficiency of a long-distance belt conveyor, which can reduce the friction between the roller and the belt by setting a lubrication device during actual belt transportation, and increase the friction between the driving roller and the belt by an adhesive device in the driving part, so as to effectively reduce the power of the belt conveyor without slipping and improve the transportation efficiency.

[0011] To achieve the above purpose, the utility model adopts the following technical solutions: a device for reducing the efficiency of a long-distance belt conveyor, comprising a belt conveyor support, a roller arranged on the upper part of the belt conveyor support and a driving roller at the head, and a belt tensioned and connected to the roller and the driving roller;

[0012] A lubricating device for reducing the friction between the roller surface and the belt contact surface is arranged parallel to the outer side of the roller, the lubricating device is located on the side of the bottom of the roller away from the belt, and the lubricating device is fixedly connected to the belt conveyor bracket and is in contact with the outer circumferential surface of the roller;

[0013] The driving roller is also provided with an adhesive device for increasing the friction between the surface of the driving roller and the contact surface of the belt. The adhesive device is located directly above the driving roller on the side away from the roller. The adhesive device includes a solvent tank, a control valve and a solvent distribution rod arranged parallel to the driving roller. The solvent tank is connected to the solvent distribution rod and a control valve is arranged between the two.

[0014] Furthermore, the lubricating device is provided with a lubricant which is compatible and durable with the belt material.

[0015] Furthermore, the lubricant is lubricating oil or lubricating grease.

[0016] Furthermore, an adhesive having adhesion and durability to the belt material is arranged in the agent tank.

[0017] Furthermore, the adhesive is a viscous adhesive or an adhesive liquid.

[0018] Furthermore, the cross-sectional area of ​​the upper end of the reagent tank is larger than that of the lower end.

[0019] Furthermore, the dosage dispensing rod is provided with a plurality of dosage leakage holes or dosage leakage grooves, and there is line contact or point contact between the dosage dispensing rod and the belt.

[0020] The beneficial effect of the utility model is that the device of the utility model can reduce the friction between the roller and the belt by arranging a lubrication device during actual belt transportation, and increase the friction between the driving roller and the belt by an adhesive device in the driving part, thereby effectively reducing the power of the belt conveyor without slipping and improving the transportation efficiency.

The solvent tank 601 is connected to the dispensing rod 603 and a control valve 602 is installed between the two.

[0029] The agent tank 601 is filled with an adhesive that has adhesion and durability with the material of the belt 3 to ensure its stability and reliability during operation. The adhesive is a viscous adhesive or an adhesive liquid.

[0030] Among them, the upper end cross-sectional area of ​​the reagent groove 601 in the adhesive device 6 is larger than the lower end cross-sectional area, which facilitates the uniformity and smoothness of the liquid.
