Heat preservation and heating system and method adopted before preassembling of liner plate of crusher dynamic cone

Abstract

The invention belongs to the technical field of beneficiation crushers, and particularly relates to a heat preservation and heating system and method adopted before preassembling of a liner plate of a crusher dynamic cone. The system comprises a heat preservation cover, a temperature sensor, a heating device and a temperature control box. A sensor mounting hole and two symmetric resin infusion holes are formed in the heat preservation cover, and the resin infusion holes are communicated with injection holes reserved in the conical-barrel-shaped liner plate of the crusher dynamic cone. The heating device is composed of cross bottom frames, a round bottom plate, a set of guiding and limiting plates, a heating lamp holder and a set of radiation heating lamps, and the guiding and limiting plates are evenly distributed. The heat preservation cover is composed of a heat preservation layer and an outer shell. Iodine-tungsten lamps are adopted as heating elements to carry out heat radiation heating on the interior of the conical-barrel-shaped liner plate, heating temperature of the conical-barrel-shaped liner plate is even, and the temperature can be freely adjusted; and heat preservation measures are taken on the conical-barrel-shaped liner plate, it is guaranteed that the conical-barrel-shaped liner plate is replaced in an efficient and energy-saving manner under low-temperature environment, and meanwhile resin solidification time is shortened.

[0002] The moving cone liner of the crusher is a cone-shaped liner that is set on the moving cone body and fixed by bonding. It is also a necessary measure to protect the moving cone body from being damaged. With the continuous operation of the crusher, the crushing time Continuing, the cone-shaped liner on the outside of the moving cone body is gradually worn down, and it needs to be replaced after the wear reaches the limit, otherwise the moving cone body itself will be damaged, resulting in overhaul or scrapping of the equipment

When replacing, it is necessary to fill resin between the new mantle liner and the mantle body as a fixed filler. When changing in winter, due to the low temperature of the mantle liner storage and installation environment, the gap between the mantle liner and the mantle body The fixed filler resin in the gap will not solidify for a long time due to the low temperature. If the resin is installed in the crusher before it is solidified and put into operation, it is easy to cause the movable cone liner to loosen and fall off after a short running time. Not only the newly replaced dynamic The cone liner cannot be used and the resin of the filling dynamic cone liner is lost, and it is easy to cause damage to the body of the crushing motor cone, so the dynamic cone liner must be heated before pre-installation

[0003] The conventional heating method for the moving cone liner is to use an electric blanket and a fire. The electric blanket can only cover the outer surface of the moving cone liner. The temperature conducts heat from the outside to the inside, and the conduction speed is slow. Due to the limitation of the shape of the electric blanket , the outer surface of the liner cannot be completely covered, and the fire pile is used to heat the inside of the moving cone liner. Due to the influence of the flame height of the fire pile, the temperature of the upper part of the moving cone liner is high while the temperature of the lower part is low, and smoke and dust are generated and pollute the work. surroundings

These two methods have the disadvantages of uneven heating temperature of the moving cone liner, no heat preservation measures, high energy consumption, and the temperature of the liner cannot be controlled artificially.
