Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection and resource utilization, and in particular to a device for mineralizing and fixing carbon by utilizing mine solid waste. Background Art

[0002] With the continuous development of the industrial field, mines are mined in large quantities, and mining activities generate a large amount of solid waste. These solid wastes not only occupy a large amount of land resources, but may also cause environmental pollution. Therefore, a device that can utilize mine solid waste for mineralization and carbon fixation is developed to recycle solid waste. After recycling, the solid waste needs to be reacted with the help of a reactor. There are the following deficiencies in the process of solid waste recovery reaction:

[0003] First, after the solid waste is crushed, it needs to be transported to the reactor by a transport vehicle, and the feed ports of the crusher and reactor need to be closed manually, which increases the cost and operation steps of solid waste transportation.

[0004] Secondly, solid waste will produce harmful gases in the reactor, which will spread in the air and easily pollute the surrounding environment and cause harm to the health of people nearby;

[0005] In addition, smaller particles in solid waste can easily clog the carbon dioxide emission holes, resulting in a smaller contact range between solid waste and carbon dioxide, and prolonging the reaction time of solid waste. Summary of the Invention

[0006] The present invention discloses a device for mineralizing and fixing carbon by using solid waste from mines. The device controls a crushing motor to drive a crushing roller to rotate to crush the solid waste. The reaction gas enters an injection pipe and is sprayed toward the inner wall of an inner tank. The curved setting of the injection pipe prevents the solid waste from clogging the injection pipe. The solid waste reacts evenly and quickly. The automatic control effect of the heat regulator is achieved by controlling the drive motor, and the heat regulator can automatically heat the heating structure.

The heating structure can be a heating wire or a heating plate. The heating structure and the heat regulator 8 are electrically connected, and the effect of slowly heating the heating structure is achieved by adjusting the heat regulator 8.

[0050] The working principle of this embodiment is as follows:

[0051] During installation, first install an inner liner 101 inside the reactor 1, install a sealing cover 2 on the top of the reactor 1, and seal the top of the reactor 1 with the sealing cover 2. Install a set of detection structures 3 on the outside of the reactor 1 and secure them with bolts. Install a stirring electric motor 4 and a set of crushers 5 on the top of the sealing cover 2. Install a stirring rod at the bottom of the driving shaft of the stirring electric motor 4. It is necessary to install corresponding stirring teeth on the basis of the stirring rod to stir the solid waste. Install a detector 302, a heat regulator 8, and a drive motor 6 on the top of the mounting plate of the reactor 1 respectively. Install the detector 302 and the heat regulator 8 on the top of the mounting plate with bolts and secure them. Install a set of drive mechanisms 7 on the outside of the positioning shell 501.

[0052] During use, the solid waste to be reacted is first placed at the position of the positioning shell 501, the reaction gas is connected to the drainage pipe and the air inlet sleeve 201, and the crushing motor 502 is controlled to drive the crushing roller 503 to rotate to crush the solid waste. The crushed solid waste falls directly into the interior of the reactor 1. The reaction gas enters the injection pipe 10101 and sprays toward the inner wall of the inner liner 101. The curved setting of the injection pipe 10101 prevents the solid waste from clogging the injection pipe 10101. The diffusion groove 10102 can evenly spread the reaction gas discharged from the injection pipe 10101 inside the inner liner 101, so that the solid waste inside the inner liner 101 and the reaction gas are evenly contacted, so that the solid waste reacts evenly and quickly. The automatic control effect of the heat regulator 8 is achieved by controlling the drive motor 6, and the heat regulator 8 can automatically heat the heating structure.

[0053] When the electromagnet is powered off, the support spring pushes the sliding gear 704 back to its original position and engages with the first rack 705. At this time, the crushing roller 503 rotates, which drives the cover plate 701 to move horizontally. The cover plate 701 seals the upper portion of the positioning housing 501, and the crushing roller 503 is effectively protected. When the second rack 706 moves, the control valve is automatically closed.

[0054] The depressurized gas inside the reactor 1 can effectively enter the interior of the detector 302. The model of the detector 302 is selected according to needs. A model that can detect gas in the existing technology is selected. When the detector 302 detects harmful gas, it will automatically alarm. At this time, the staff will replace the filter element in time, and the corresponding valve needs to be closed during replacement.
