Description

Self-adaptive material lifting device and method for ceramic proppant cooler Technical Field The invention belongs to the field of material lifting devices, and particularly relates to a self-adaptive material lifting device and method for a ceramic proppant cooler. Background The ceramic proppant is a key material for increasing the yield of oil and gas field hydraulic fracturing, and the production process mainly comprises raw material preparation, granulation, high-temperature sintering and cooling. The sintered ceramsite has a temperature of above 1200 ℃ and must be rapidly cooled to below 80 ℃ by a cooler to be screened and packaged. The single-cylinder cooler is widely applied due to simple structure and reliable operation, and the working principle is that the cylinder body rotates to drive the internal lifting plate to continuously lift and throw high-temperature ceramsite to form a material curtain, and the material curtain performs high-efficiency countercurrent heat exchange with the reversely flowing cold air, and simultaneously recovers waste heat. In the prior art, the lifting plate of the cooler is generally fixedly installed, namely, a steel plate with a certain radian and angle is fixed on the inner wall of the cylinder body through welding or bolts. In the production process of ceramsite propping agent in actual production, the characteristics of materials (such as particle size distribution and water content) and the feeding flow rate of the fixed type lifting plate are often changed due to the fluctuation of an upstream process. The angle and shape of the fixed type lifting blades cannot adapt to the change, and the curtain is unevenly distributed. When the flow is large, the materials are excessively stacked, the material curtain is excessively thick, the ventilation resistance is increased, the heat exchange efficiency is reduced, dust is easy to fly and particles are easy to crush, when the flow is small, the material curtain is sparse, even a 'cavity' appears, the cooling air is short-circuited, and the heat recovery efficiency is rapidly reduced.
