Description
The technical field is as follows:
the utility model belongs to the technical field of coal mine production equipment, concretely relates to wear-resisting ceramic polyurethane composite sheet.
Background art:
Chute troughs used for coal chute in coal mine production enterprises are usually made of steel plates. The material sliding surface of the material sliding groove is repeatedly in contact friction with the coal material, the material sliding surface of the steel plate is not wear-resistant, acid-base resistant, poor in corrosion resistance and short in service life, material blocking is often caused due to material sticking, and the steel material sliding groove used for a long time needs to be replaced after being seriously corroded, so that time and labor are wasted, and the production cost is increased. Therefore, it is necessary to design a wear-resistant ceramic polyurethane composite board for manufacturing a coal chute
The utility model has the following contents:
The utility model aims at providing a wear-resisting ceramic polyurethane composite sheet for making coal charge swift current silo, this composite sheet stand wear and tear, and corrosion-resistant, acid and alkali-resistance, long service life just can avoid sizing and putty phenomenon, has solved equipment putty phenomenon effectively, and economy is suitable for, easily promotes on a large scale and uses.
The utility model adopts the technical proposal that: a wear-resistant ceramic polyurethane composite board comprises a steel plate frame, a ceramic plate and a polyurethane lining plate; the composite plate consisting of the ceramic plate and the polyurethane lining plate is positioned in the steel plate frame, and the polyurethane lining plate, the ceramic plate and the steel plate frame form a whole through a hot vulcanization process; the steel plate frame on one side of the polyurethane lining plate is welded with a steel belt, and the steel belt is welded with a connecting bolt.
Furthermore, the ceramic plate is formed by ceramic plates which are wear-resistant ceramic plates.
further, the number of the steel strips is at least two.
the utility model has the advantages that: the wear-resistant ceramic polyurethane composite board is wear-resistant, corrosion-resistant, acid-base-resistant and long in service life, can avoid the phenomena of material sticking and material blocking, effectively solves the problem of material blocking of equipment, reduces production cost, is simple in structure, reasonable in design, economical and applicable, and is easy to popularize and use on a large scale.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the first embodiment;
FIG. 2 is a bottom view of FIG. 1;
Fig. 3 is a top view of fig. 1.
The specific implementation mode is as follows:
example one
Referring to the figures, the wear-resistant ceramic polyurethane composite plate comprises a steel plate frame 1, a ceramic plate 2 and a polyurethane lining plate 3; the composite plate consisting of the ceramic plate 2 and the polyurethane lining plate 3 is positioned in the steel plate frame 1, and the polyurethane lining plate 3, the ceramic plate 2 and the steel plate frame 1 form a whole through a hot vulcanization process; a steel belt 4 is welded on the steel plate frame 1 on one side of the polyurethane lining plate 3, and a connecting bolt 5 is welded on the steel belt 4; the ceramic plate 2 is formed by ceramic plates which are wear-resistant ceramic plates; the number of the steel strips 4 is at least two.
The composite plate is installed on a steel frame of the chute through connecting bolts to be assembled into the chute for chute. The wear-resisting ceramic surface is used as a material sliding surface, the ceramic has good wear resistance and strong trafficability characteristic, and the material sticking phenomenon can not occur, so that the material blocking phenomenon of equipment is avoided. The polyurethane has good expansion and contraction performance, can play a role in buffering, and reduces the generation of noise.
the composite lining plate adopts an advanced hot vulcanization process to vulcanize the wear-resistant ceramic plate in a steel plate frame filled with polyurethane, and the steel plate frame is provided with countersunk bolts. The composite board can be customized, can be processed into various shapes, and can be made into a lining board by selecting composite materials with various thicknesses according to the abrasion working condition to form a firm abrasion-resistant layer. The use temperature of the composite board is-50 ℃ to 80 ℃; the ceramic wafer contains alumina with content more than or equal to 95 percent; rockwell hardness is more than or equal to 85 HRA; the compressive strength is more than or equal to 850 MPA; coefficient of thermal expansion: 7.2X 10-6 m/m.k. The ceramic composite board is characterized in that: good shock resistance, abrasion resistance, corrosion resistance, high temperature resistance and acid and alkali resistance. The use is convenient, the small blocks and the special-shaped sizes are adopted, and the special-shaped device is suitable for mounting various special-shaped devices. The ceramic material is not stuck and blocked, and the problem of equipment blocking is effectively solved due to the high-strength corrosion-resistant characteristic of the ceramic. The polyurethane has strong wear resistance, impact resistance and corrosion resistance, has a certain buffering effect, and reduces noise in use.
