Abstract
The utility model relates to the improvement technology of industrial furnaces, and discloses a gas-electricity mixing roller kiln. The gas-electricity mixing roller kiln is provided with a thermal insulation kiln body which is divided into a pre-heating section, a sintering section and a cooling section, wherein a driving roller device is installed inside the kiln body; multiple heaters arranged at equal intervals in a row are installed at the position, located at the lower portion of the kiln body, of the pre-heating section; multiple heaters which are arranged at equal intervals in an upper row and a lower row are installed on the sintering section and located in the kiln body. The gas-electricity mixing roller kiln is characterized in that the heaters in the pre-heating section and the sintering section comprise gas burners and electric heaters, the gas burners and the electric heaters are staggered in every row, and two adjacent gas burners are located on the left side and the right side of the kiln body in a staggered mode respectively. The flue gas emission is reduced greatly, heat losses are reduced effectively, the energy conservation effect is remarkable, and the kiln is mainly used for production in the ceramic industry.
Description
Technical field
The utility model relates to Industrial Stoves improvement technology, and especially a kind of pneumoelectric is used roller kilns with.
Background technology
At present, tradition roller kilns are generally full gas heating or full electric heater heating, the deficiency of gas furnace maximum is that flue gas is taken away heat energy and accounted for the more than 10-20% of energy wastage in bulk or weight, and the shortcoming of full electric heater heating furnace is: 1. because airstream in kiln is slow, and the more bad control of the wider temperature difference of kiln body; 2. kiln design can not be too large, otherwise that shortage of electric power area faces power load is large, is limited by supply of electric power.
Summary of the invention
The purpose of this utility model is exactly to overcome gas heating or two kinds of roller kilns of electric heater heating shortcoming separately, and comprehensively both advantages, provide a kind of pneumoelectric to use roller kilns with.
Concrete scheme of the present utility model is: for existing gas heating roller kilns, improve, it has insulation kiln body, kiln body is divided into preheating section, the section of burning till and cooling section, in kiln body, driving roller device is installed, at preheating section, be positioned at the heater that kiln body bottom is provided with the some equidistant layouts of a row, and be arranged in kiln body in the section of burning till, be provided with, the heater of the some equidistant layouts of lower two row, it is characterized in that: the heater in described preheating section and the section of burning till includes fuel burner nozzle and two kinds of heaters of electric heater, two kinds of heaters interlaced arrangement in every row, and adjacent two fuel burner nozzles lay respectively at kiln body left and right sides interlaced arrangement.
Described in the utility model, between heater, spacing is 50-80mm between two.
Electric heater described in the utility model is comprised of 6-10 electrothermal tubes that are arranged side by side.
In the utility model kiln body, not only fuel burner nozzle is installed but also electric heater is installed, adopted electric Hybrid Heating mode, the feature that makes pure gas heating or pure electric heater heat two heat forms is inherited, overcome the shortcoming of two kinds of heat forms simultaneously, there are two aspects: 1. smoke discharge amount significantly reduces, effectively reduce hot loss of energy, energy resource consumption reduces, and comprehensive energy declines 10-20%; 2. high-speed fuel gas burner, the stirring to gas in kiln, has reduced local temperature difference, has a narrow range of temperature, and is unlikely to again power load excessive, can manufacture the roller kilns of larger specification.

In figure: 1-preheating section, the 2-section of burning till, 3-electrothermal tube, 4-fuel burner nozzle, 5-kiln body, 6-driving roller device.
The specific embodiment
Referring to Fig. 1-4, the utlity model has insulation kiln body, kiln body is divided into preheating section 1, the section of burning till 2 and cooling section (save in figure, generally connect right-hand member), driving roller device 6 is installed in kiln body, at preheating section 1, be positioned at kiln body bottom 12 heaters of equidistantly arranging of one row are installed, and be arranged in kiln body in the section of burning till 2, be provided with, 12 heaters of equidistantly arranging of the every row of lower two row, particularly: the heater in described preheating section 1 and the section of burning till 2 includes fuel burner nozzle 4 and two kinds of heaters of electric heater, two kinds of heaters interlaced arrangement in every row, and adjacent two fuel burner nozzles 4 lay respectively at kiln body left and right sides interlaced arrangement.
Described in the present embodiment, between heater, spacing is 50-80mm between two, is specially 60mm.
Electric heater described in the present embodiment is comprised of 6-10 electrothermal tubes 3 that are arranged side by side, and is specially 8.
Claims (3)
1. a pneumoelectric is used roller kilns with, there is insulation kiln body, kiln body is divided into preheating section, the section of burning till and cooling section, in kiln body, driving roller device is installed, at preheating section, be positioned at the heater that kiln body bottom is provided with the some equidistant layouts of a row, and be arranged in kiln body in the section of burning till, be provided with, the heater of the some equidistant layouts of lower two row, it is characterized in that: the heater in described preheating section and the section of burning till includes fuel burner nozzle and two kinds of heaters of electric heater, two kinds of heaters interlaced arrangement in every row, and adjacent two fuel burner nozzles lay respectively at kiln body left and right sides interlaced arrangement.
