Abstract
The utility model relates to the field of tunnel furnaces, in particular to a drying kiln which comprises a flue gas main outlet and flue gas inlets which are arranged at the top of the drying kiln. A hollow flue which is connected with the flue gas inlets is arranged in the wall body which forms a kiln body. Air holes which are used for communicating with the flue and the internal part of the kiln are arranged on the inner wall of the wall body at intervals. The number of the flue gas inlets is two and the flue gas inlets are arranged at the top of the kiln along the length direction of a tunnel at intervals, wherein one flue gas inlet is arranged at or close to the middle part of the drying kiln and the other flue gas inlet is relatively close to the outlet end of the drying kiln. The flue gas main outlet is arranged between the flue gas inlets arranged at or close to the middle part of the drying kiln and the inlet end of the drying kiln. Since the utility model properly utilizes the waste heat of the kiln to improve the drying efficiency of unburned bricks, the situation of seasoning crack of the unburned bricks is prevented, the finished product rate is improved and the environmental pollution is reduced.
Description
Technical field
The utility model relates to the tunnel cave field, is specifically related to a kind of drying kiln.
Background technology
Present brick and tile manufacturing enterprise uses the tunnel cave technology in a large number, idiographic flow is: adobe needs air-dry 4 to 5 days under natural environment after machine-shaping, enters subsequently and carries out drying in the drying kiln, enter tunnel cave preheating, sintering, insulation, cooling again, final molding.Have the following disadvantages in the specific operation process: at first, because adobe air-dry overlong time in room temperature environment, this just needs a large amount of places, has increased the production cost of enterprise; Secondly, the cigarette recuperation of heat gas that is used to dry adobe in the drying kiln is all taken from the soaking zone of tunnel cave, because the tunnel kiln temperature is lower when soaking zone, and cigarette recuperation of heat gas has the loss of heat in transmittance process, after entering drying kiln, can make the baking temperature of whole stove not enough, often make the drying effect in the kiln relatively poor, cause adobe in the later stage sintering process, to be ftractureed easily, especially for the thin-walled brick, cracking phenomena is more serious; At last, produce in the drying kiln the waste gas that contains pollutant such as a large amount of sulphur directly be discharged in the atmosphere, caused the serious environmental pollution.
Summary of the invention
The purpose of this utility model provides a kind of drying kiln, is intended to rationally utilize the stove waste heat to improve brick bat drying efficient, avoids the dry and cracked phenomenon of adobe to improve yield rate simultaneously.
For achieving the above object, the utility model has adopted following technical scheme: a kind of drying kiln, comprise and be positioned at flue gas general export and the gas approach that place, drying kiln kiln top is provided with, the body of wall inside that constitutes the kiln body is provided with the flue of the connection flue gas general import of hollow, the body of wall inwall is interval with the eye of wind that is used to be communicated with flue and kiln inside, gas approach is two and is arranged in Yao Dingchu at interval along the length of tunnel direction, one of them gas approach is located on or near the drying kiln middle part, the close drying kiln port of export that another gas approach is relative, flue gas general export are located between the entrance point of the gas approach that is located on or near drying kiln middle part and drying kiln.
The beneficial effects of the utility model are: after adopting said structure, adobe only need be placed on open-air 4 to 5 hours and can enter drying kiln after machine-shaping dries, and does not need a large amount of places, has lowered the production cost of enterprise; In addition, because it is to the high temperature setting by low temperature that this drying kiln temperature inside begins to end to the port of export from entrance point, thereby make its drying effect better, and because temperature is moderate, so promptly help rapid draing, can avoid adobe dry and cracked again, and adobe is not easy to crack in the sintering process in later stage, especially for the thin-walled brick, can significantly improve its Forming Quality; At last, because the flue gas general export of drying kiln directly is communicated with outside filter plant, the sulphur-containing exhaust gas that is produced in the kiln all need filter through filter plant before entering atmosphere, has reduced the pollution to environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of structure shown in Figure 1.
The specific embodiment
A kind of drying kiln, comprise and be positioned at flue gas general export 20 and the gas approach 10 that place, drying kiln kiln top is provided with, body of wall 30 inside that constitute the kiln body are provided with the flue 31 of the connection flue gas general import of hollow, body of wall 30 inwalls are interval with the eye of wind 32 that is used to be communicated with flue 31 and kiln inside, gas approach 10 is two and is arranged in Yao Dingchu at interval along the length of tunnel direction, one of them gas approach 10 is located on or near drying kiln middle part and is communicated with soaking zone in the tunnel cave, introduce the cigarette recuperation of heat gas of relatively lower temp in the soaking zone, the close drying kiln port of export that another gas approach 10 is relative also is communicated with the section of burning till of tunnel cave, cigarette recuperation of heat gas with relative higher temperature in the introduction section of burning till, flue gas general export 20 is located between the entrance point of the gas approach 10 that is located on or near drying kiln middle part and drying kiln, thereby the temperature difference that has produced in the stove from low to high distributes, improved the drying efficiency of adobe, as illustrated in fig. 1 and 2, the arrow direction is the air current flow direction among the figure, and wherein the hollow arrow direction of Fig. 2 is the traffic direction of kiln car in the drying kiln.
Owing to adopt the design of two gas approach 10, get rid of timely for making its cigarette hot waste gas that produces, the concrete scheme that adopts is: flue gas general export 20 is communicated with two flue gases and divides outlet 21, flue gas divides outlet 21 to be positioned at place, drying kiln kiln top, two flue gases divide outlet 21 places to be equipped with blower fan 40, and blower fan 40 is oppositely arranged.Certainly also can design a plurality of exhanst gas outlets, also can reach the effect of better eliminating cigarette hot waste gas.
Flue gas general export 20 is owing to be connected with outside filter plant, and the sulphur-containing exhaust gas that is produced in the kiln all need filter through filter plant before entering atmosphere, has reduced the pollution to environment.
