Abstract
The utility model relates to a kiln provides a poor energy -conserving tunnel cave of low temperature, keeps using when improving waste heat utilization of blast apparatus, the problem of the meticulous applique goods of the poor influence of the outer surface temperature in solving, and the outer surface temperature keeps unanimous in making to guarantee the quality of burning till of product. Include the cyclic annular kiln body that constitutes by inner wall and outer wall, the kiln is internal including burning the section of banking up with earth and cooling zone, be equipped with heating device on the inner wall of the fever section of banking up with earth and the outer wall, be equipped with blast apparatus in the cooling zone, its characterized in that: heating device is for inserting the heating wire among the parallel circuit, the heating wire is parallel distribution from top to bottom, and the heating wire quantity of outer wall compares for 1.1-1.4 with the heating wire quantity of inner wall: 1.
Description
Technical field
The utility model relates to a kind of kiln, particularly relates to a kind of Low Temperature Difference energy-saving tunnel kiln.
Background technology
Spin-tunnel kiln is the Thermal Equipment that modern continous way is burnt till, and is widely used in the baked for producing of ceramic product.Be generally the kiln body of loop tunnel shape, is burn training section in kiln body within charging aperture, be divided into different temperatures on request technique fire, before discharging opening, being provided with cooling section, for lowering the temperature to the product burnt till, facilitating feeding during discharging, through test, for effectively utilizing the heat from burning training section spilling, the product burnt till is lowered the temperature simultaneously, carry out air-cooled at cooling section application bellows toward burning training section direction, heat can be trapped in and burn in training section, promote the even announcement of heat in kiln, the method has energy-saving effect, but bring the problem making burning training section outer wall heat be less than inwall simultaneously, as Fig. 1, the burning training section 12 ' of the wind direction kiln body that the blowing device 2 ' being positioned at kiln body cooling section 11 ' is produced by boasting returns, outer wall 13 ' will be run in process and produce break-in, also to take while upsetting air flow direction the outer wall 13 ' heat at place, make outer wall 13 ' neighbouring temperature comparatively inwall 14 ' slightly low 5 ° ~ 15 °, paste in the burning process of special marble paper at pottery, comparatively strict to the requirement of temperature, the error of said temperature easily makes product quality decline, produce and hand over substandard products.
Utility model content
Therefore, for the problems referred to above, the utility model provides a kind of Low Temperature Difference energy-saving tunnel kiln, while retaining the application raising utilization rate of waste heat of blowing device, solve the problem of inside and outside wall temperature differences effect meticulous applique goods, inside and outside wall temperature is consistent, burn till quality with what ensure product.
For achieving the above object, the utility model is achieved through the following technical solutions: 1, a kind of Low Temperature Difference energy-saving tunnel kiln, comprise the ring-type kiln body be made up of inner and outer wall, comprise in described kiln body and burn training section and cooling section, the described inner and outer wall burning training section is provided with heater, blowing device is provided with in described cooling section, it is characterized in that: described heater is the heating wire in access parallel circuit, described heating wire is parallel distribution from top to bottom, and the heating wire quantity of outer wall is 1.1 ~ 1.4:1 with the ratio of the heating wire quantity of inwall.
Further improvement is: the heating wire on described outer wall is Aludirome, and the heating wire of described inwall is nickel chromium triangle electrothermal alloy.
Further improvement is: described blowing device comprises air outlet box and external air blast, and described air outlet box is provided with air outlet, and described air outlet is provided with catch by rotating shaft, and described catch regulates air outlet angle by rotating.
Further improvement is: described air outlet box is located at inside and outside two side or kiln body roof respectively.
By adopting preceding solution, the beneficial effects of the utility model are: the blowing device retaining cooling section is lowered the temperature to the pottery burnt till, the heat brought out by the room of burning till can be returned again and blow back, the full burning of heat is made to train room, improve the advantage of utilization rate of waste heat and minimizing energy consumption, also make the temperature difference of burning training section inside and outside wall reduce, be applicable to the decal paper product that firing temperature requirement is higher, improve product quality.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of background technology;
Fig. 2 is the utility model structural representation.
