Description

sludge taking device

The present invention relates to a sludge taking device.

In general, the water treatment process such as sewage and wastewater discharged from industrial sites is treated through several stages such as settling tanks and aeration tanks. For example, when discharging sewage, wastewater or raw water, it is inevitably discharged through a water treatment process at the final end of the drainage channel to preserve water quality.

In the sewage treatment process, raw water flowing in from households or industrial sites is treated with chemicals, and oxygen is supplied in the aeration tank, and then the microorganisms contained in the raw water aggregate and settle as it flows over to the settling tank. The supernatant water filtered through the trough is treated with a final chemical and discharged into a river.

In order to remove the sediment generated during the sewage treatment process, a sludge collector must be installed, and a typical example of such a sludge collector is a chain flight type sludge collector.

This chain plate type sludge collector (hereinafter referred to as a 'sludge collector') is installed in the settling tank at the initial and final stages of inflow of raw water in the sewage treatment process.

The sludge collector installed in this way rotates the chain by receiving the driving force from the driving unit composed of the motor and the reducer located on the upper part of the settling tank. The chain is equipped with a rake, which rotates along the chain and picks up the sludge to the top.

Here, when retrieving a long foreign material such as a rake with a rake, when the foreign material stands vertically, the upper end of the foreign material is retrieved and the sludge collector device is jammed, and the chain is broken due to the jam.

In addition, the sludge collector inserted into the settling tank has a plurality of flat bars spaced apart from each other, but there was a problem that foreign substances were caught between the flat bars, and there was an inconvenience of requiring work to remove them.

In addition, the sludge collector installed to have a slope of a predetermined angle (about 70°) has a problem in that it is difficult to install while maintaining a predetermined angle when the upper portion of the installation space is narrow.

In this case, the driving unit 50 may include a motor for rotating the shaft, a sprocket rotatably provided on the upper portion of the main body 10 and rotating the rail, and a transmission unit for shearing the driving force by connecting the shaft and the sprocket.

The flat bar 14 is provided spaced apart between the pair of chains 30 , and a plurality of flat bars 14 are provided in the longitudinal direction of the main body 10 . Sewage may flow between the flat bars 14 .

At this time, sludge may be caught between the flat bars 14 , and the caught sludge may be removed through the rake part 40 moving along the main body 10 .

On the other hand, referring to FIGS. 4 to 6 , the rake unit 40 has both ends elastically coupled to the chain 30 , and rotates when a load is applied from the sludge to avoid the load. That is, as the load applied to the rake unit 40 disappears, the load is not applied to the chain 30 , and the chain 30 does not break.

First, on one side of the chain 30 where the pair of chains 30 face each other, the first locking protrusion 31 is formed to protrude. In addition, on one side of the chain 30 , the coupling shaft 32 is formed to protrude from the first locking protrusion 31 .

The rake part 40 includes a support plate 41 , an elastic part 43 , a coupling plate 44 , and a moving plate 45 .

The support plate 41 is rotatably provided at the end of the coupling shaft 32 , and a second locking projection 42 is formed on one side to face the first locking projection 31 .

The elastic part 43 is provided on the coupling shaft 32 , and one end and the other end are respectively coupled to the first locking protrusion 31 and the second locking protrusion 42 , and have an elastic force.

In this case, the elastic part 43 may be formed of, for example, a torsion spring. That is, when the support plate 41 rotates, it can be returned to its original state by the elastic part 43 .

The coupling plate 44 protrudes from the other side surface of the support plate 41 .

The moving plate 45 is coupled to the coupling plate 44, and a removal protrusion 46 inserted between the flat bars 14 is formed at the lower end thereof, and is moved along the chain 30 to pick up sludge. is formed with

In addition, when a load is applied from the sludge, the moving plate 45 is moved to avoid the load by rotating around the coupling shaft 32 with the lower end downward and the upper end upward, and when the load disappears, the elastic part 43 of It returns to its original state by the elastic force.

On the other hand, the coupling plate 44, a long hole 47 is formed, and the moving plate 45 is integrally coupled to the long hole 47 by a coupling means.

At this time, the moving plate 45 can adjust the depth at which the removal protrusion 46 is inserted between the flat bars 14 by the long hole 47 .

In addition, in the moving plate 45, in a state in which the removal protrusion 46 is inserted between the flat bars 14, a concave groove is formed so that one side from which the sludge is retrieved is inside and the sludge is contained, and the upper end is the upper part. The bent portion 48 is formed to support the sludge from falling by being bent.

In addition, the moving plate 45 may have a plurality of drainage holes so that sewage can be discharged while collecting the sludge, but the present invention is not limited thereto.

In addition, on one side of the chain 30, the engaging shaft 32 and the protruding locking projection 33 is formed spaced apart.

At this time, the locking protrusion 33 allows the moving plate 45 to rotate in only one direction.

That is, the moving plate 45 is rotated by the elastic part 43 , one side of which is supported by the locking jaw 33 and the removal protrusion 46 inserted between the flat bars 14 is rotatable only downward. Do.

Accordingly, the removal protrusion 46 is rotated to the lower side of the flat bar 14 by the rotation of the moving plate 45 and comes out to pass through the sludge caught between the flat bars 14 .

In addition, when the removal protrusion 46 moves upward in a state inserted between the flat bars 14, a load is applied to the sludge caught between the flat bars 14 and rotates downward, so that the sludge can be rotated without being caught. It is curved toward the bottom toward the end so that it can be bent.

For example, when the removal protrusion 46 is concave to support the sludge, a load is further applied to the removal protrusion 46 so that the removal protrusion 46 may be broken or the chain 30 may be damaged.

That is, as the outer peripheral surface of the removal protrusion 46 is protruded and formed to be convex, the phenomenon of sludge jamming can be eliminated.

On the other hand, the rake unit 40 further includes a sensor unit and a communication control unit.

The sensor unit is provided on the locking jaw 33 , and detects whether it is spaced apart from the locking jaw 33 according to the rotation of the moving plate 45 .

The communication control unit transmits a message to a preset manager terminal when the sensor unit detects that the support plate 41 is rotated and spaced apart from the locking jaw 33 .

At this time, the communication control unit detects the sensor units provided in each of the plurality of moving plates 45 , and when the adjacent sensor units detect a preset number of times consecutively, a message is transmitted to the manager terminal.

That is, when sludge is caught in the flat bar 14 while the plurality of moving plates 45 rotate, the moving plate 45 rotates about the coupling shaft 32 . At this time, when rotating, the moving plate 45 and the locking jaw 33 are spaced apart, and the sensor unit detects this.

Here, the separation between the moving plate 45 and the engaging protrusion 33 is continuously sensed from the successive sensor unit whenever the moving bar passes through the position where the sludge is caught. This is because solid sludge is sandwiched between the flat bars 14, and requires confirmation and maintenance by an administrator.

Therefore, by sending a message to the manager terminal, the manager can check and remove the sludge caught in the flat bar 14, as well as smoothly maintaining the removal protrusion 46 or the chain 30 breakage can be prevented in advance.
