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 includes a shell 1, a grinding assembly 2, a diversion assembly 6 and a dust removal assembly 8. The bottom of the shell 1 is equidistantly installed with three groups of supports The seat 102, the housing 1 can provide the installation position for the surrounding components, the support seat 102 can support and fix the bottom of the housing 1, so as to improve the overall stability of the device, an access door is installed on the front side of the housing 1 107. The access 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 front of the housing 1 away from the access door 107 is installed with a servo motor 106, and the servo motor The output end of the 106 extends to the inside of the grinding chamber 3 and is fixedly connected to the...

Embodiment 2

[0035] see Figure 1-4 , a blast furnace slag dry processing device based on high temperature slag waste heat recovery proposed by the present invention, compared with the first embodiment, this embodiment also includes a fixed seat 302 installed at the bottom of the grinding chamber 3, and the fixed seat 302 can be used for grinding The bottom of the chamber 3 is limited and fixed, thereby increasing the installation stability of the grinding chamber 3, and a vacuum pump 301 is installed on the top of the grinding chamber 3. The vacuum pump 301 can be of the HG-30L type. The interior is pumped, so that a low-pressure environment is formed inside the vacuum chamber 303, and the overall thermal insulation performance of the grinding chamber 3 is improved. A rotor 201 is installed inside the grinding chamber 3, and the rotor 201 can drive the surrounding components to rotate, which can further improve the blast furnace. The slag is crushed and ground by applying pressure, and pr...

Abstract

The invention discloses a blast furnace slag dry processing device based on high-temperature slag waste heat recovery, comprising a shell, a grinding component, a diversion component and a dust removal component. There is a vacuum chamber, a grinding assembly is installed inside the grinding chamber, a rotor is installed in the grinding assembly, a drive shaft is installed at both ends of the rotor, three sets of installation grooves are installed on the outer side of the rotor, and the inner side of the casing away from the grinding chamber is installed with a heat exchange compartment. In the invention, a rotor is installed inside the grinding chamber, and the surrounding components can be driven by the rotor to rotate synchronously, so that the blast furnace slag inside the grinding chamber can be driven to move, and the blast furnace slag can be processed by the cooperation of the rotor and the inner wall of the grinding chamber. Crushing and grinding, so that the blast furnace slag with irregular shape and size can be pulverized into fine high-temperature powder, so that the heat exchange heat treatment inside the blast furnace slag can be facilitated.

Description

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