Embodiment 1

[0033] see Figure 1-7, a blast furnace slag dry processing device based on high temperature slag waste heat recovery proposed by the present invention, including a shell 1, a grinding assembly 2, a flow guide assembly 6 and a dust removal assembly 8, and three sets of supports are equidistantly installed on the bottom of the shell 1 Seat 102, the shell 1 can provide the installation position for the surrounding components, the support seat 102 can support and fix the bottom of the shell 1, so as to improve the overall stability of the device, and the front side of the shell 1 is equipped with an inspection door 107, the inspection door 107 can open the front side of the housing 1, so as to facilitate the maintenance of the components inside the housing 1, the side of the housing 1 away from the inspection door 107 is equipped with a servo motor 106, and the servo motor The output end of 106 extends to the interior of the grinding chamber 3 and is fixedly connected with the dr...

Embodiment 2

[0035] see Figure 1-4 , a blast furnace slag dry process device based on recovery of high-temperature slag waste heat proposed by the present invention. Compared with Embodiment 1, this embodiment also includes a fixed seat 302 installed on the bottom of the grinding cabin 3, and the fixed seat 302 can be used for grinding The bottom of cabin 3 is limited and fixed, thereby increasing the installation stability of grinding cabin 3, and a vacuum pump 301 is installed on the top of grinding cabin 3. Internal pumping, so that the inside of the vacuum chamber 303 forms a low-pressure environment, and improves the overall thermal insulation performance of the grinding cabin 3. A rotor 201 is installed inside the grinding cabin 3. The rotor 201 can drive the surrounding components to rotate, and then the blast furnace The slag applies pressure for crushing and grinding, and the inertia of the rotor 201 can exert pressure on the blast furnace slag, thereby reducing the power consump...

Abstract

The invention discloses a blast furnace slag dry processing device based on high-temperature slag waste heat recovery. The device comprises a shell, a grinding assembly, a flow guide assembly and a dust removal assembly, a grinding cabin is mounted at one side in the shell, a vacuum cavity is formed in the grinding cabin, the grinding assembly is mounted in the grinding cabin, a rotor is mounted in the grinding assembly, driving shafts are mounted at the two ends of the rotor, three sets of mounting grooves are formed at the outer side of the rotor, and a heat exchange cabin is mounted at the side, away from the grinding cabin, in the shell. According to the blast furnace slag dry processing device, the rotor is installed in the grinding cabin, surrounding assemblies can be driven to rotate synchronously through the rotor, and therefore blast furnace slag in the grinding cabin can be driven to move, and the blast furnace slag can be crushed and ground through cooperation of the rotor and the inner wall of the grinding cabin; and therefore, the blast furnace slag with irregular shapes and sizes can be crushed into fine high-temperature powder, and heat in the blast furnace slag can be conveniently subjected to heat exchange treatment.

Description

technical field [0001] The invention relates to the technical field of blast furnace slag dry processing, in particular to a blast furnace slag dry processing device based on high temperature slag waste heat recovery. Background technique [0002] Furnace steelmaking is a relatively common metal forging process in heavy industry. By using a blast furnace to heat and melt metals such as steel, the metal can produce various industrial products with special properties. When the blast furnace smelts steel, the inside of the furnace will produce A large amount of blast furnace slag, blast furnace slag can be used to produce other industrial raw materials, and the interior of blast furnace slag also contains a lot of heat energy, which has high energy utilization value. Traditional blast furnace slag has low energy utilization rate in post-processing , thus increasing the internal energy loss of the blast furnace slag. At this time, a blast furnace slag dry processing device based...
