Description
Technical Field
The utility model belongs to the power plant sweetener field especially relates to a belt hydroextractor belt load bearing roller.
Background
At present, the desulfurization method of a power plant generally adopts limestone-gypsum wet desulfurization, the byproduct gypsum produced in a desulfurization system is finished by a gypsum dehydration system, a vacuum belt dehydration system is the final link of dehydration, and the operation stability of the vacuum belt dehydration system directly influences the desulfurization efficiency and the dehydration rate. The main equipment of the vacuum belt dewatering system is a belt dewaterer. At present, the belt bearing carrier roller is extremely easy to damage due to unreasonable design form and material, and the belt is easy to slip after being damaged, so that the safety production is influenced. The main defects of the belt bearing carrier roller are that the material is plastic, and the service life of the bearing carrier roller is rapidly reduced due to the heavier belt and the high moisture of the equipment operation condition; secondly, bearings of the belt bearing carrier roller are embedded in the carrier roller, so that bearing chambers on two sides of the carrier roller are easily damaged during replacement, and the carrier roller basically becomes a disposable spare part; thirdly, the supporting roller is expensive in unit price and high in replacement cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a belt hydroextractor belt load bearing roller to solve above-mentioned technical problem.
The utility model provides a belt dewaterer belt load bearing roller, including the bearing roller body, the bearing roller body is hollow steel pipe, the steel pipe both ends are inlayed and are had solid steel column, the part that the steel column stretches out to the steel pipe both sides is equipped with endocentric bearing frame, it has the bearing to inlay on the bearing frame, the bearing frame be used for with belt feeder body or belt feeder body support fixed connection.
Furthermore, the steel pipes and the steel columns are made of carbon steel.
Furthermore, the joint of the steel pipe and the steel column embedding part adopts a welding mode.
Further, the bearing adopts a center-adjustable bearing.
Further, the surface of the steel pipe is lined with acid-resistant rubber, and the lining rubber is 8 +/-0.5 mm in thickness; the exposed part of the bearing carrier roller of the belt is coated with a glass flake anticorrosive coating.
By means of the scheme, the belt bearing carrier roller of the belt dehydrator is convenient and fast to maintain when the carrier roller bearing is damaged, the bearing is located outside, the problem of the bearing can be found in time, and the problems of belt slipping, deviation and the like caused by the fact that the carrier roller does not rotate are reduced; the carrier roller body cannot be damaged during maintenance, the maintenance cost of the carrier roller is greatly reduced, and the belt supporting effect is good; the material is common, the processing is simple, and the reutilization property is better; it is suitable for water and corrosive liquid environment.
The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.

Fig. 1 is a schematic structural view of a belt bearing carrier roller of a belt dehydrator.
Reference numbers in the figures:
1-a bearing seat; 2-a bearing; 3-steel column; 4-a steel pipe; 5-acid-resistant rubber.
Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
Referring to fig. 1, the middle part of the belt bearing carrier roller of the belt dehydrator is a seamless steel pipe 4 with specification phi 89 x 5.5, the bending degree of the steel pipe 4 is not more than 1.5mm, the ovality is not more than 1mm, two sides are respectively embedded with a solid phi 77 +/-0.25 mm steel column 3, the embedding depth is more than one eighth of the total length of the steel pipe 4, and the processing meets the requirement of double-shaft concentricity of the two sides; the steel tube 4 and the steel column 3 are made of carbon steel, the steel column 3 extends out of a part, the joint of the embedded part adopts a welding mode, the extending part is machined into a bearing position according to the design size and is used for installing the bearing 2, the bearing 2 adopts 33208RSH series, the bearing is convenient for installing and adjusting a carrier roller, and the service life can be prolonged because the two sides of the bearing are provided with steel skeleton nitrile rubber contact type seals; the surface of the steel pipe 4 is lined with acid-resistant rubber 5, the thickness of the lining rubber is 8 +/-0.5 mm, the steel pipe is wear-resistant and corrosion-resistant, and the exposed part (such as an extending part and a bearing seat) is coated with a 0.5mm glass flake anti-corrosion coating; the bearing is inlaid on the bearing seat 2, and the bearing seats 2 on the two sides are fixed on the belt conveyor body or a reset support.
The carrier roller body of the embodiment is hollow, the specification of the steel pipe 4 is phi 89 x 5.5, the total length of the carrier roller is 1.8 m, the weight is about 20kg, the gravity of a belt bearing point is about 300N, and the radial load of a bearing is adopted to meet the bearing requirement.
The belt bearing carrier roller of the belt dehydrator has the advantages that when the carrier roller bearing is damaged, the maintenance is convenient, the bearing is positioned outside, the problem of the bearing can be found in time, and the problems of belt slipping, deviation and the like caused by the fact that the carrier roller does not rotate are reduced; the carrier roller body cannot be damaged during maintenance, the maintenance cost of the carrier roller is greatly reduced, and the belt supporting effect is good; the material is common, the processing is simple, and the reutilization property is better; it is suitable for water and corrosive liquid environment.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
