Abstract
The utility model discloses a perlite expanding electric furnace, comprising a furnace body shell. A furnace lining, a temperature controlling apparatus and an electrothermal element are arranged in the shell. An upward included angle is formed between the upper surface of the front segment and the upper surface of the back segment of a thread placing brick arranged on the furnace lining, the electrothermal element is arranged on the thread placing brick, and an inner high temperature internal bladder is arranged in the furnace. The electric furnace can full automatically sinter and swell low, medium and high perlite products of with different specific gravities, such as common perlite, perforated perlite, surface-melted type perlite, vacuum round perlite, hollow perlite, etc. The utility model has no environmental pollution, saving energy, convenient installation, simple structure and small investment, and the perlite expanding electric furnace fundamentally changes traditional production method of perlite products.
Description
Technical field
The utility model belongs to the stove and accessory of making perlite product, is specifically related to a kind of perlite expansion electric furnace.
Background technology
Perlite ore expand into product and uses coal furnace to add thermal expansion in China always, because burning coal produces a large amount of flue dust, environmental pollution is serious, and can only produce low-grade expanded perlite product, can't produce high-grade expanded perlite product; Labour intensity is big, and behaviour is a worker for coal smoke and dust and peripheral personnel cause certain harm.
Summary of the invention
The purpose of this utility model is to provide a kind of perlite expansion electric furnace, to overcome above-mentioned defective.
The technical solution of the utility model is: perlite expansion electric furnace comprises the body of heater shell, establish furnace lining in the shell, temperature regulating device, heating, establish on the furnace lining put a brick leading portion upper surface and and above the section surface of back between form upwards angle, heating is located to be put on the brick, high temperature inner bag in being provided with in the stove.
This electric furnace can the full-automatic common perlite of sintering grow, perforate perlite, melt surface type perlite, the round perlite of vacuum, hollow perlite, various different specific weights perlitic etc. low in high pearl rock goods.Environmentally safe, high energy saving, easy for installation, simple to operate, invest the little production method that fundamentally changes traditional perlite products.

The specific embodiment
As shown in Figure 1, perlite expansion electric furnace is connected and composed 8 meters furnace body by six joint construction units.Every joint is formed by connecting by flange 11.Every joint structure is: establish furnace lining 2 in the steel shell 1, furnace lining 2 is made of fan-shaped refractory brick 3 of lightweight and heat-insulation layer 4.A brick 5 is put in the fan-shaped refractory brick 3 higher slice embeddings of lightweight, and heating 6 is located at puts a brick 5, and puts a brick 5 and establishes steel inner container 7 apart.Heating 6 in every joint or the per two joint structures connects a temperature regulating device 8, and promptly the supporting 4-6 platform of electric furnace attemperating unit divides the 4-6 district to carry out temperature automatically controlled to electric furnace.Adopt the benefit of subregion temperature control to be to adjust best power output, guarantee that the perlite expanding product of sintering is all qualified.
Attemperating unit comprises cabinet 81 as shown in Figure 3, the Displaying Meter of establishing in the cabinet 81 82, indicator lamp 83, switch 84, air switch 85, current transformer 86, controllable silicon 87, fuse 88.
Put a brick as shown in Figure 2, form upwards angle between the leading portion upper surface 52 of brick body 51 and the back section surface upper surface 53.Adopt the benefit of said structure to be that when the heating expanded by heating heating can not fall down from putting a brick.
Claims (3)
1, perlite expansion electric furnace, it comprises the body of heater shell, establishes furnace lining in the shell, temperature regulating device, heating, it is characterized in that establishing on the furnace lining put a brick leading portion upper surface and and above the section surface of back between form upwards angle, heating is located to be put on the brick, high temperature inner bag in being provided with in the stove.
2, perlite expansion electric furnace according to claim 1 is characterized in that it is to be interconnected to constitute by said structure unit at least two joints, and typical structure is six joints.
3,, it is characterized in that the heating in described every joint or the two joint structures connects an attemperating unit as perlite expansion electric furnace as described in the claim 2.
