Detailed Description

The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.

As shown in fig. 1 to 4, a shuttle kiln device for producing black bricks comprises a kiln body 1, wherein a black brick placing frame 2 for stacking the black bricks and drying the black bricks by using the waste heat of the kiln body 1 is arranged above the kiln body 1; the kiln body 1 with set up flue gas pipeline 3 between the blue or green brick rack 2, flue gas pipeline 3 be used for with the inside flue gas of kiln body 1 is discharged blue or green brick rack 2 utilizes the flue gas waste heat to make and is located the blue or green brick is dry on the blue or green brick rack 2. The blue brick needs to be dried before being fired, generally a drying room or natural drying is adopted in the prior art, the drying time is longer, the waste heat of the smoke of the existing shuttle kiln is not utilized generally, the heat is lost due to white and white, and the energy-saving requirement is not met. And even if not utilizing the flue gas waste heat, shuttle kiln top temperature is also higher, sets up blue or green brick rack 2 above the shuttle kiln, then places the blue or green brick, also can play certain drying effect. Therefore, the purpose of better energy conservation is achieved through the embodiment, the drying time of the grey bricks is shortened, and the production efficiency of enterprises is improved.

The flue gas pipeline 3 of the above embodiment may be one or more, and is used for discharging flue gas or tail gas generated by burning natural gas in the kiln body 1. The installation position of the flue gas pipeline 3 can be the upper part or the side surface of the kiln body 1, and fig. 1 shows that the flue gas pipeline 3 is positioned at the upper part of the kiln body 1, but other situations can also be of course, or the installation position of the flue gas pipeline 3 in the prior art.

In order to uniformly heat and dry the black bricks on the black brick placing frame 2, a smoke uniformly-distributing pipe 4 can be arranged on the black brick placing frame 2, as shown in fig. 1. The flue gas uniform distribution pipe 4 is communicated with the flue gas pipeline 3, and a flue gas outlet 5 is arranged on the flue gas uniform distribution pipe 4. The flue gas uniform distribution pipe 4 is distributed at the bottom or the lower part of the blue brick placing rack 2 in a certain shape, so that the flue gas is uniformly discharged. Namely, the flue gas with the residual heat in this embodiment enters the flue gas uniform distribution pipe 4 through the flue gas pipeline 3, is dispersed through the flue gas uniform distribution pipe 4, and is discharged from the flue gas outlet 5.

The arrangement of the flue gas uniform distribution pipe 4 can be various shapes, one of which is shown in fig. 2, for example, the flue gas uniform distribution pipe is arranged in a ring shape, so long as the flue gas uniform distribution can be realized, and the embodiment is not exhaustive.

And the side surface of the kiln body 1 can be provided with stairs and the like so as to facilitate the maintenance of the kiln body 1 or the structure of the above embodiment and the manual work of loading and unloading the grey bricks and the like. Of course, for the way the cyan bricks are placed in the cyan brick placing frame 2, it is preferable to realize this by mechanical means.

In addition, in order to better place the blue bricks on the blue brick placing frame 2, namely, in order to prevent the flue gas uniform distribution pipe 4 or other devices of the above embodiment from interfering with the loading and unloading of the blue bricks, a bottom plate 6 with holes can be arranged above the flue gas uniform distribution pipe 4. The black bricks are directly placed on the bottom plate 6 with the holes, the smoke uniform distribution pipe 4 is arranged below the bottom plate 6 with the holes, and the smoke in the smoke uniform distribution pipe 4 can be discharged from the bottom plate 6 with the holes. This embodiment is through the mode that sets up foraminiferous bottom plate 6 under the dry condition of not influencing the blue brick, has also made things convenient for the loading and unloading of blue brick.

As shown in fig. 3, since there is a large amount of dust or sand in the environment of green brick production, in order to prevent the sand from falling into the flue gas distribution pipe 4 from the flue gas outlet 5, a first filter screen 7 for preventing sand may be disposed on the flue gas outlet 5, and the first filter screen 7 may be a steel wire mesh or the like.

As shown in fig. 4, in order to reduce the harmful substances in the flue gas in the kiln body 1, the flue gas can be purified and then discharged into the atmosphere, so as to meet the requirement of environmental protection. For example, a flue gas cleaning device 8 may be arranged on the flue gas duct 3. Through this gas cleaning device 8 to gas cleaning, can reduce harmful substance to a certain extent after the purification, then the equal stringing 4 of rethread flue gas, then be used for the drying of blue or green brick again, discharge into in the natural environment after the drying. The flue gas purification device 8 of the present embodiment may be a purification device in the prior art, or may be a purification device specially provided at a later stage.

The flue gas purification device 8 in one embodiment may be an activated carbon disposed in the flue gas purification device 8, and the activated carbon may perform a purification function to some extent.

As shown in fig. 1, an airflow revolving device 9 is provided in the kiln body 1. Since the grey brick is easily heated unevenly during the firing process, generally, the temperature of the upper part of the grey brick is higher than that of the lower part, so that a certain rotating airflow is preferably formed in the kiln body 1, and therefore, the assumption of the present embodiment is to arrange an airflow rotating device 9 in the kiln body 1. One specific embodiment of the airflow slewing device 9 may be:

the airflow swiveling device 9 includes:

an air inlet pipeline 10 communicated with the upper side inside the kiln body 1;

an air outlet pipeline 11 communicated with the lower side inside the kiln body 1;
