Description

[0001] The present invention relates to a three-stage transferring conveyor for sludge drying,

The present invention relates to a three-stage conveyor for drying sludge, and more particularly to a sludge drying conveyor for drying sludge such as food wastes, paper, and fabrics by reducing heat loss to a maximum extent to reduce waste of energy In order to make the sludge uniformly dried by injecting the same pressure at the beginning and the end in the line pipe and the hot air injection pipe to which the air is introduced and transported, the stirrer stirring the sludge so that the sludge is evenly dried, To a sludge drying transfer conveyor system.

In general, many resources are needed according to the development of industry, and many resources that can not reach the content in the process of producing them are not classified as waste, so they must be disposed of as waste.

In particular, fossil fuels use underground resources such as coal, oil, and natural gas, which is the majority of the energy currently used by humankind.

Such fossil fuels have been used for a long time due to industrial development, and the amount of fossil fuels has been rapidly increased due to the increase in the amount of used fuels.

The applicant of the present invention invented a sludge drying conveyor for collecting and drying various types of sludge such as food waste, paper, and wastes generated in a sewage / sewage system for use as an alternative fuel.

That is, a microwave and a fan are installed on the conveying conveyor and a heat is installed on the lower end of the conveyor so that the sludge is dried while being conveyed on the conveying conveyor by using the microwave generated from the microwave and the heat generated by the heater .

The sludge drying conveyor simultaneously operates the microwave and the heater to simultaneously heat the microwave generated in the microwave and the heat generated in the heater.

However, the above-described sludge drying conveyor has a disadvantage that unnecessary energy is wasted by operating the microwave and the heater at the same time and drying at about 250 ° C.

However, the above method has a disadvantage in that the microwave generated in the microwave is heated at a high speed while passing through the water molecules contained in the sludge and heated.

In order to solve such a problem, it has been found that a blocking plate is installed at the lower end of a conveying conveyor for conveying the sludge so that the microwave passes through the sludge and is then reflected to heat the sludge again. However, And a reflector was installed at the lower end of the conveying conveyor to simply reflect the microwave, which was a waste of energy.

As another improvement method, a sludge recycling system using combustion heat of sludge developed by the present inventor has been disclosed. The recycling system includes a mixer for mixing a dehydrated sludge having a water content of 80% and a drying sludge having a moisture content of 20% And a pellet molding machine for pelletizing the mixed sludge having a water content of 60% mixed through the mixer is installed. In order to dry the mixed sludge formed into a pellet shape through the pellet molding machine, the outer peripheral surface is protected by a heat insulating material A drying chamber in which a plurality of discharge ports for discharging water vapor generated from the mixed sludge are formed, a combustion chamber provided outside the drying chamber for generating heat by burning the dried mixed sludge, Of the mixed sludge is transferred from the first stage to the second stage And a motor is mounted on one side of the belt conveyor to drive the fan to transfer heat generated in the combustion chamber to the hot air inflow path And a fan installed at one side of the belt conveyor and installed at one side of the belt conveyor to drive the fan to blow the drawn air into the discharge port Patent Application No. 10-2014-0145606).

However, this sludge recycling system can save energy by using the heat inside the system generated by burning the mixed sludge again to dry the sludge. However, even if the sludge is heated at high temperature due to the flow of steam generated by the drying of the mixed sludge It did not dry quickly, so it took a lot of time to run the system and it caused a lot of energy consumption.

In addition, the sludge conveyed through the belt conveyor has a disadvantage in that the sludge located on the lower side contacting with the belt conveyor does not directly convey the hot air to the sludge.

In addition, since the thickness of the line pipe is the same at the beginning and the end, the pressure applied to the pipe and the pressure at the outlet are different. Thus, the spraying pressure of the hot air is changed, and the drying speed becomes slower as the sludge moves to the rear of the pipe. Since the heater that applies the hot air is installed in the hot air generator of the large inner diameter of the line pipe and is lost by the hot air generator and the hot air generator is installed in the middle part of the line pipe, it is difficult to repair the heater when the heater breakage occurs. And the oil of the chain that rotates the gear installed in the stirrer is dried, which causes a disadvantage in that the noise of the stirrer is severe.

Therefore, it is possible not only to save energy by shortening the drying time of the sludge by maximizing the efficiency of the hot air, but also to completely dry the sludge located at the lower side, to have a constant sludge drying rate before and after the drier, The drying system of the sludge and the drying method are desperately required.

In the conventional method, a plurality of branch pipes are horizontally installed in a multi-stage manner horizontally in a long circular main pipe for supplying hot air.

In the above method, since the length of the line pipe is long, hot air is strongly injected into the hot air injection pipe at the entrance of the air, and hot air is weakly injected into the hot air injection pipe at the end, The sludge can not be uniformly sprayed, and the sludge is not completely dried.

Therefore, the above method has a disadvantage that the drying speed is slower as the sludge rides on the belt conveyor and moves toward the tail.

In the conventional method, the heater for heating hot air is provided with a hot air generator with a large inner diameter in the middle of the line pipe, and the heat generated by the heater of the hot air generator is transmitted to the line pipe, There is a problem in that the waste is wasted.

In addition, in the above-mentioned conventional patent, a plurality of stirrers are installed on the conveying conveyor and are rotated by the gears and the chains, respectively.

However, in the above method, since the sludge conveyed on the conveying conveyor is mixed with the rotary type stirrer provided on the conveying conveyor, the sludge is not uniformly spread on the conveying conveyor but is gathered on one side. The inside of the sludge gathered in one place can not be dried because of not contacting the sludge evenly.

In addition, since the hot air generator is installed in the middle of the pipe, the heat generated by the hot air generator is transmitted to the stirrer, There is a problem that the noise is heavy and the gear and the chain are easily worn or damaged.
