Detailed Product Description: | 1 coal bunker liner causes of coal mines, power plants, coal storage bunker pier basically made of cast concrete, the surface is not smooth, friction coefficient, high water absorption, which is often caused by bonding and blocking positions the main reason. Especially in the soft coal mining, pulverized coal and more moisture is large, blocking positions particularly serious accident. 2 coal storage bin in the form of a common block bunker clogging in two forms: one is wet pulverized first bonded warehouse wall, layer by layer superimposed together, finally forming a shape similar to the rat hole inside the warehouse, and then coal loading will cause blocking positions; the other is due to friction between the large wet pulverized coal blocks, combined it with the silo wall outside the friction is large, when the bunker is full of coal, the lower conical section a form similar to the coal mouth bagging jammed and rusted shape (commonly known as bypass). Gate when put down only a very small part of coal, coal due to the bagging and block the upper compartment. In the northern area of ??coal mining enterprises cold winter proof measures if limited, prone to moisture content of the material and the silo wall caused by freezing together blocking positions. 3 coal storage bin blocking consequences for many years to solve the problem of bonded warehouse block, people have thought of many ways: such as in a warehouse wall tiling, laying steel, air gun or hit with a hammer, it is not completely resolved, and Artificial poke bunker and often results in personal injury 4 coal bunker liner performance principle by the large number of research and experiments, and finally decided to use UHMWPE sheet lined bunker, the use of self-lubricating UHMWPE sheet and non-adhesive, in order to reduce the friction coefficient , to solve blocking positions phenomenon. 5 coal bunker liner installation method uses large pieces of sheet metal nail fixed to the wall of the barn, which completely solved the problem of bunker bonded warehouse blocked. Generally without covered all positions, as long as the lower coal bunker discharge port portion tapered section and its upper part silo lining shop about 1 meter to solve the rat hole and bagging two forms caused by the blocking positions. 6 coal bunker liner installation precautions when coal bunker liner installation, operation, or in the case of a larger change in the ambient temperature, fixed form liner must consider it free to expand or contract. Any fixing method, the design should take into account the beneficial flow of bulk material, and the screw head is always buried in the liner mother. For thicker liner, Edge should be cut at 45 degrees. Thus, the allowable length change, and form a smooth plastic flat in the silo, is conducive to the flow of material. Special attention when installing the coal bin liner: 1, the installation process, the liner bolt countersunk flat requirements must be lower than the board; 2, when the coal bin liner product is installed using bolts per square meter should not be less than 10; 3, the gap between each liner plate should not be larger than 0.5cm (adjusted according to the plate to give the ambient temperature during installation); Note 7 when using 1, the initial use, three to be material storage silo to the entire warehouse capacity two-thirds, then the discharge line. 2, operation, always leave the material on the heap inside the warehouse Jincang point blanking material, and keep the material in the warehouse storage capacity of more than half the entire warehouse capacity. 3, prohibited material directly impact liner. 4, different hardness particles of various materials, are not free to replace the material and flow, For change, no larger than the original design capacity of 12%, free to change the material or traffic will affect the life of the liner. 5, ambient temperature, generally not more than 100 ℃. 6 Do not use external damage to its structure and random loose fasteners. 7, the material in the warehouse standstill period should not exceed 36 hours (less viscous materials do not stay in the warehouse, to prevent caking), moisture content less than 4% of the material may be appropriate to extend the rest time. 8, at lower temperatures, please pay attention to the material in the bin still time, to avoid frozen blocks. 8 coal bunker liner solve effect through Henan, Shandong, Shanxi, Hebei and other provinces showed numerous coal mines and power plants, effectively blocking positions to solve the problem, the effective utilization of their bunker by 20% --50% to 100 %, to avoid production interruptions and stabbed warehouse accidents caused due to blocking positions, reducing the Bunker crushing rate, saving clearance costs. greatly reducing the loading time, reducing pressure wagon phenomenon, reduce labor intensity of workers, social benefits and economic benefits are significant. 9 coal bunker liner role for coal power generation is coal-pulverizing coal bunker system, an important part of the large and medium-sized power plant unit, the main plant coal bunker most used steel and steel. As the material flow in the warehouse, its friction with the silo wall steel siding easy to damage, but could easily lead to rough steel surface coal block. Thus, the inner wall of coal bunker designed both consider adding a layer located higher than ordinary steel abrasion resistance 5-6 times smooth surface coal bin liner, in order to extend the useful life of coal bunker, reduce the maintenance rate. For one unit 600 MW units, within its main plant coal storage capacity of about 3 618 m3, need lined surface area of ??about 1122 m2, and if 2 × 300 MW units, the main plant of coal storage capacity of about 3 228 m3, lined surface area of ??about 1608 m2, large quantities. If a substantial loss of condition appears to run, on the one hand lead to the loss of the base steel sheet protection and accelerated wear to the destruction, on the other hand lined with sheet metal debris can clog the bunker discharge port, causing coal supply block, this time will have to be shut down maintenance, not only affects the normal production, but also caused huge economic losses. Thus, good design and construction of coal bunker liner, to ensure the safe operation of the unit is of great importance. |
