Problems solved by technology

However, during the actual use (3-6 months), the following problems were found: 1. The glue is not resistant to high temperature ≤ 80°C; 2. It is not resistant to moisture and water; 3. The bonding strength is low ≤ 2- 3MPa, resulting in the detachment of the wear-resistant ceramic rubber plate from the metal roller
[0008] (1) After long-term use on the outer side of the steel cylinder, it is easy to slip and affect the normal operation of the drum;
[0009] (2) When the friction protrusions on the outer side of the roller are severely worn, in order to ensure the grip force, the entire roller needs to be replaced, which costs a lot;
[0010] (3) Replacing the roller requires stopping production, which reduces productivity and increases labor intensity and safety hazards;
[0011] (4) High cost of maintenance management and enterprise operation

Embodiment 1

[0033] figure 1 , 2 As shown, a drum composite ceramic repair regeneration and life extension method includes a drum 1, the surface of the drum 1 is composited with a ceramic layer 2, and a tortoise shell net 3 or an anchor nail 4 is welded between the ceramic layer and the drum;

[0034] Specific steps are as follows:

[0035] The first step: clean the outer surface of the drum;

[0036] Step 2: Weld ceramic anchors or tortoise shell nets on the outer surface of the drum;

[0037] Step 3: Stick a layer of viscous ceramic material masterbatch on the outer surface of the drum, and adjust the dimensional accuracy of the cylindrical surface;

[0038] The fourth step: bake and solidify the ceramic masterbatch;

[0039] Step 5: Use a 3000°C high-temperature flame to rapidly heat and fire along the surface of the cured ceramic masterbatch, so that the temperature from the surface of the ceramic masterbatch to a depth of 5mm reaches 2030°C, and the surface of the ceramic masterba...

Embodiment 2

[0043] figure 1 As shown, a drum composite ceramic repair regeneration and life extension method includes a drum 1, the surface of the drum 1 is composited with a ceramic layer 2, and a tortoise shell net 3 is welded between the ceramic layer and the drum;

[0044] Specific steps are as follows:

[0045] The first step: clean the outer surface of the drum;

[0046] Step 2: Weld ceramic anchors or tortoise shell nets on the outer surface of the drum;

Abstract

The invention discloses a roller composite ceramic repairing, regenerating and life-prolonging method, and relates to the field of conveying machineries, the roller composite ceramic repairing, regenerating and life prolonging method comprises a roller, a ceramic layer is compounded on the surface of the roller, ceramic anchoring nails or hexsteel are welded between the ceramic layer and the roller, and a newly formed roller cylinder is rough in surface and large in friction force through thickening and curing of the ceramic layer. The slipping phenomenon is avoided, the conveying belt efficiency is improved, the electromechanical efficiency of conveying driving is improved, more energy is saved, concave-convex damage to the cylindrical surface of the roller caused by abrasion of the roller is repaired, and in order to guarantee the uniformity of gripping force, avoid replacement of the whole roller, reduce the cost, improve the service life of the roller due to high-hardness abrasion resistance and prolong the production halt period required by replacement of the roller, the productivity is improved, the labor intensity is also reduced, the potential safety hazard of safety production and the safety risk caused by high-strength and complex position replacement are reduced, and the maintenance management and enterprise operation cost is reduced.

Description

technical field [0001] The invention relates to the field of conveying machinery, in particular to a method for repairing, regenerating and prolonging the service life of a roller composite ceramic. Background technique [0002] The belt conveyor is a mechanical conveying device that is driven by friction to transport materials in a continuous manner. It can form a material conveying process from the initial feeding point to the final discharging point on a certain conveying line. , it can not only transport broken materials, but also transport items. In addition to pure material transport, it can also cooperate with the requirements of the process in the production process of various industrial enterprises to form a rhythmic flow. work transport line. Its function is the guarantee of safe and stable production. The roller is an important component in the belt conveyor machinery. The driving and turning of the conveyor belt needs to be completed by the roller wheel. Especia...
