An environmentally friendly and high-efficiency quartz stone calciner

Abstract

The invention discloses an environment-friendly and high-efficiency quartz stone calcining furnace. The calcining furnace includes a furnace body, a heating unit and a control unit. The furnace body includes a furnace body, and is matched with a furnace cover arranged on the side wall of the top of the furnace body, and The supporting feet are arranged on the outer side wall of the lower end of the furnace body; the heating unit is arranged in the inner cavity of the furnace body, which includes a heat conduction cylinder and a heating rod arranged in the heat conduction cylinder; and a control unit, which is electrically connected to the heating rod, It includes a control box located outside the furnace body and a monitoring component located in the furnace body, and the control box is electrically connected to the monitoring component; the furnace body in the present invention is a novel combined structure, which effectively distinguishes the inner cavity of the furnace body, It is convenient for the later maintenance of the furnace body, and at the same time, the more reasonably distributed heating units greatly improve the heating effect of the furnace body and are easier to maintain; the monitoring component can monitor the heating temperature in the furnace in real time to improve the energy saving effect of the heating unit. The furnace cover structure is easy to keep warm and charge.

Description

technical field [0001] The invention relates to the technical field of energy-saving calcination furnaces, in particular to an environmentally friendly and high-efficiency quartz stone calcination furnace. Background technique [0002] In industrial production, quartz stone is calcined using hearth furnaces and electric furnaces. The structure of the hearth stove is very similar to that of the stove, the difference is that the hearth stove places quartz stone on the place where the pot was originally placed on the stove, and the stove mouth is blocked with a thick steel plate. When the furnace cavity of the hearth furnace is filled with quartz stones, a thick insulation cover is covered on the top of the furnace body, and the bottom of the furnace body is heated with coal or coke. It takes at least ten hours to burn the quartz stones to clinker. This calcination method causes the quartz stone inside the furnace cavity to be heated unevenly, and the temperature in the furnac...

AI Technical Summary

Problems solved by technology

Although the electric furnace is more environmentally friendly than the hearth furnace, the resistance wire of the electric furnace is easy to burn out when heated at high temperature, and it is very inconvenient to maintain after it is burned out. At the same time, the specific temperature of the internal heating of the electric furnace cannot be controlled, which is very important for today's increasingly tense electric energy. a serious waste

[0003] Furthermore, the traditional calciner has an integrated stove structure, and the process of unloading and residue cleaning is relatively complicated. At the same time, when quartz stone is added to the calciner, the position of the furnace mouth will lose heat with the opening, and the quartz stone may It will block the feed port, which will affect the overall calcination efficiency
