Description

Sludge transfer device

The present invention relates to a sludge transfer device, and more particularly, without using a transfer pump, sludge is introduced into a chamber by using air pressure from a primary sealed evaporator, and the sludge introduced into the chamber is secondary by air pressure. It relates to a sludge transfer device that is transferred to a sealed evaporator to perform the next process.

General waste generated in daily life and industrial waste generated at industrial sites have relatively low moisture content, so they are easily incinerated and then landfilled. Due to this difficulty, the development of a sludge incineration device is being actively carried out so that dewatering, drying, and incineration of the sludge can be performed more efficiently.

In general, incineration of sludge for incineration or composting of sewage sludge, after dewatering the sludge to a moisture content of 75% or less, passes it through a drying furnace equipped with a transport path that provides sufficient exposure conditions and drying time to reduce the moisture content to less than or equal to the designated moisture content. This is done through the process of drying and incineration in an incinerator using the dried sludge as fuel.

These conventional dryers and incinerators are provided with a transport path for efficiently exposing the sludge to heat. Most of them are horizontally moved over a certain length by placing a plurality of metal conveyors or caterpillars that transport the sludge in the horizontal direction in the vertical direction. It is configured to repeat descending at a predetermined interval, and even if it is transported on an inclined path, it has a circular structure as it is transported by a screw path or distributed around a central axis.

In addition, when sludge is transported using a transfer pump, since the sludge contains ash, minor breakdowns occur frequently, and the lifespan is shortened within 3 months, making it difficult to fix, and the operation rate is very low. Operational efficiency is greatly reduced. On the other hand, as the space inside the discharge conveying pipe is reduced due to the adhesion of ash, an overload of the conveying pump is generated according to the increase of the conveying pressure, which causes a malfunction.

In order to solve the above causes and facilitate the process, it is a device for transferring sludge by attaching a pressure sensor, a temperature sensor, and a level switch to an airtight container so that these mechanisms work well in a continuous process.

In the existing technology, the sludge cake or contaminants discharged through the dewatering cake and collateral waste treatment from the waste sealed container using pneumatic and hydraulic pressure are collected in the sludge sealed storage container, and then transported to a designated place through the piping line using compressed air. If the sludge cake or sludge is clogged at the outlet of the sludge storage container, a waste airtight container using pneumatic and water pressure that can be transported by pushing through the blockage using water pressure and pneumatic pressure at the same time to a predetermined place is suggested. has been

In another prior art, a valve to achieve a closed structure in the sludge temporary receiving unit in a sludge sealing container using air pressure that can be smoothly discharged from the sludge temporary receiving unit even with high viscosity sludge and stably transported to the loading box of the sludge conveying vehicle is installed and an air injection port connected to the air injection pipe is provided on the upper part of the valve so that when the valve is opened, it is applied to have a means for removing foreign substances by spraying high-pressure air to the valve and the valve accommodating frame part, and the air in the sludge temporary accommodating part A noise reduction device is installed at the joint connection part of the air injection pipe for injecting the have.

On the other hand, the dehydration cake or impurities discharged from the dehydrator that lowers the moisture content of the sludge generated in the sewage treatment plant and the contaminant treatment machine that treats substances mixed with foreign substances are collected and transferred to the cake storage hopper using air. In the pneumatic conveyor system comprising: and a weighing hopper part, a transfer line, and a control part, the spring compressed according to the weight between the sealed container body and the supporting shaft to achieve precise weighing of the sealed container body or the weighing hopper part The sensing means of the first weight detection unit selected from the characteristics of the hydraulic actuator compressed according to the The second weight detection part selected from the sensors is installed between the sealed container body and the supporting shaft, so that the sealed container body or the weighing hopper part is precisely weighed, and the flange and the flange of the transfer line are transferred from the sealed container body to the cake storage hopper. The pipe cushioning material provided as an elastic and flexible material between the joints is applied in a structure where it is fitted and coupled in the form of a conical connector to prevent wear and corrosion and to have a buffer function in response to the change in weight of the first weight detection unit. A pneumatic conveyor device for transporting sludge generated in a sewage treatment plant including

As described above, the sludge was transported by pneumatic pressure, but the sludge was not transported properly because the discharge transport pipe was narrowed by the ash stuck to the exhaust transport pipe.
