Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

All electric parts and the adaptive power supply are connected through wires by the person skilled in the art, and a proper controller and encoder should be selected according to actual conditions so as to meet control requirements, specific connection and control sequence, and the electric connection is completed by referring to the following working principles in the working sequence among the electric parts, and the detailed connection means are known in the art, and mainly introduce the working principles and processes as follows, and do not describe the electric control.

Embodiment one:

the back control hot air pipeline comprises a pipeline pipe body 8, wherein the inlet end of the pipeline pipe body 8 is connected with a hot smoke outlet 1 of a hot smoke generator dryer through a flange plate 2, the outlet end of the pipeline pipe body 8 penetrates into a kiln 5 through a manhole 6, an outer wall back control hot air pipe 7 is sleeved outside the manhole 6, a through hole is formed in the back control hot air pipe 7, and the through hole is connected with a second fan 4 through a cold air pipe. The size of the flange plate is selected to be the same as the caliber of the inlet end, wherein the flange plate 2 is made of heat-resistant steel (273 phi), the pipeline pipe body 8 is made of hot steel hot smoke pipes (219 phi), the back control hot blast pipe 7 is made of heat-resistant steel (273 phi), and one side, close to the inlet end, of the pipeline pipe body 8 is connected with the first fan 3 through a pipeline and is used for pushing the wind direction kiln 5 to blow.

2. The installation and use process comprises the following steps: 2.1. the hot flue gas generator is connected with the reverse control hot air pipeline inlet flange of the device through bolts, primary air is connected with the spiral fan, and secondary air is connected with the other spiral fan.

2.2. Through the connection, be connected the fan with the hot smoke generator and send into the stove through the hot air duct of reverse control, because of the inside high temperature oven that needs of stove, in starting primary fan and supplying air, improved air supply speed and pressure like this, the inside just can improve of stove, because of inside blast into a large amount of hot-blast, the afterbody has the flue to discharge a small part, but still has slight positive pressure in the stove, and the blast will return, opens the secondary fan cooling. Thus the inlet section will be baked at low temperature.

3. Principle of: when hot air is blown to the kiln 5 from a hot flue gas generator dryer, the temperature of the air is lower and lower in the transmission process under normal conditions, but when the kiln 5 is different in structure, the temperature requirements for baking all positions are different, because the materials and the thicknesses are different, the requirements are different, in order to ensure that the manhole 6 is not damaged due to too much heat at the air inlet, the manhole 6 is sleeved with an outer wall back control hot air pipe 7, cold air is introduced into the back control hot air pipe 7 for cooling, the temperature of an air outlet is higher than that at the manhole, and the back control hot air pipe reaches the implementation control temperature of the inside, far, near and low of the kiln through the back control hot air pipe

The realization effect is as follows: through technical research and development, the device for reversely controlling the hot air pipeline is connected with the hot air outlet end of the hot air generator dryer, and plays a role in controlling the temperature of hot air of the hot air generator through the pipeline, and the implementation of high, low, high, near and low.

In particular to the situation that the required temperatures of the space in a furnace are different, the device is connected, so that the temperature is accurately controlled, the use is simple and convenient, and the best quality of kiln baking is facilitated.
