Description

Sludge storage cake hopper with collecting and draining unit {COLLECTING CHANNEL AND CATCH DRAIN FOR THE SLUDGE STORAGE CAKE HOPPER}

The present invention relates to a sludge storage cake hopper, and more particularly, to a sludge storage cake hopper provided with a collecting and draining unit for collecting and draining a filtrate flowing out of a cake hopper that temporarily stores sludge generated as a by-product during a sewage and wastewater treatment process. .

In general, sludge generated as a by-product during water purification and wastewater treatment process contains a large amount of moisture, resulting in problems such as secondary environmental pollution problems such as bad odor due to decay of residual organic matter in the sludge, and contamination of soil groundwater. It caused me to do it.

It is preferable that the sludge has as little moisture as possible. Accordingly, the sludge generated through various treatment processes undergoes a normal dewatering process, and the dewatered sludge is caked in a cake hopper for sludge storage, which is a temporary storage facility. is stored in

Afterwards, the sludge cake stored in the cake hopper is transported to the landfill by vehicle, although most of the moisture has been removed from the sludge cake through the dehydration process, but its moisture content reaches 80%, and over time, the sludge cake The moisture remaining in the

Since the filtrate is generated from the sludge cake temporarily stored in a dehydrated state, a separate water collecting device is installed at the lower part of a conventional cake hopper to collect the filtrate.

As a prior art, the sludge cake hopper leachate collection device of Patent Publication No. 10-1610043 (2016.04.01.) and the hopper device with automatic opening and closing structure of the drip tray of Registration Patent Publication No. 10-1754577 (2017.06.30.) Although it has been proposed, it requires a separate manpower or power to generate unnecessary consumption, or to be damaged as sludge is directly dropped into the water collecting device, which is difficult to maintain.

In addition, after moving the water collecting device, the gate is closed and opened separately, and then the water collecting device needs to be moved again, which increases the time required for operation.

Registered Patent Publication No. 10-1610043 (2016.04.01.) Registered Patent Publication No. 10-1754577 (2017.06.30.)

The present invention facilitates the discharge of sludge through the sludge outlet of the cake hopper body without the consumption of additional power or manpower, and minimizes the time required for operation by allowing the water collector to move simultaneously with the opening and closing of the gate As much as possible, the water collecting unit is moved before the sludge is dropped to prevent the water collecting unit from being deformed and damaged, and the maintenance cost is reduced by allowing the sludge and the filtrate to flow out by the bottom slope of the collecting unit. An object of the present invention is to provide a sludge storage cake hopper equipped with a collection and drainage unit that can be reduced.

The present invention for achieving the above object,

The sludge outlet 120 of the cake hopper body 110 is rotated to the outside and opened on both sides, and the gate 100 is provided so as to be closed by rotating inward;

a gate driver 200 provided in the lower outer part of the gate 100 and the cake hopper body 110, respectively;

a driving sprocket wheel 300 that coincides with the center at which the gate 100 rotates and is exposed to the outside;

a driving chain 400 provided so that the lower part is engaged with the driving sprocket wheel 300 and wound;

a driven sprocket wheel 500 provided to be wound in engagement with the upper portion of the drive chain 400 and supported by the cake hopper body 110;

a support arm 600 provided on the driven sprocket wheel 500;

a water collecting unit 700 provided at a lower portion of the support arm 600; and

The drainage unit 800 provided close to the lower side of the water collecting unit 700 is included so that the filtrate is usually discharged along the bottom inclined surface of the water collecting unit, and the sludge is discharged without using power or manpower. It is configured to prevent deformation and damage to the water collecting part in the process of discharging the sludge.

Accordingly, the present invention has the effect of minimizing energy consumption by not using a separate manpower or power to move the water collecting unit.

In addition, by allowing the water collecting unit and the gate to operate simultaneously through this, the time required for driving the cake hopper can be minimized.

In addition, by preventing the sludge from falling directly into the water collecting unit through this, deformation or damage of the water collecting unit is prevented, thereby extending the life of the water collecting unit.

In addition, as a part of the sludge accumulated in the water collecting unit flows and is discharged like the filtrate through this, the cost of maintenance can be reduced while increasing the drainage efficiency of the water collecting unit.

And through this, it has the effect of improving the working environment due to the shortening of the worker's movement while increasing the space utilization, and also ensuring sufficient safety.

Referring to Figure 6a,

Figure 6a is a front view showing a process in which the sludge is discharged in an embodiment of the collecting and draining port for the sludge storage cake hopper installed with the collecting and draining part according to the present invention.

In the collecting/draining port for the sludge storage cake hopper according to the present invention, some sludge falls together in the process in which the filtrate generated from the sludge temporarily stored inside the cake hopper body 110 falls downward through the gate 100 in normal times. The sludge and the filtrate that have fallen are contained in the water collection guide 712 through the water collection inlet 711 of the water collection unit 700, and the sludge and the filtrate contained in the water collection guide 712 are inclined surface portion 740. flows and is drained downward through the drain hole 730 .

Next, the filtrate containing the sludge drained to the lower part of the water collecting unit 700 is drained through the drain body 810 and the drain member 820 of the drain unit 800 and stored in a filtrate or sludge storage tank not shown. It can be sludged again.

Figure 6a is a sludge transport vehicle (SC) in this state to transport the sludge in a state in which the sludge transport vehicle (SC) is stored in the lower part of the cake hopper body 110 supported by the civil structure (EW), the drainage unit 800 is a sludge transport vehicle ( It is possible to prevent the occurrence of an interference phenomenon as it is located on the outer upper part of the SC).

Next, as the gate 100 rotates and the driving sprocket wheel 300 rotates at the same time, the driven sprocket wheel 500 is rotated by the driving chain 400 . At this time, as the diameter of the driving sprocket wheel 300 is larger than the diameter of the driven sprocket wheel 500, the driven sprocket wheel 500 rotates more, and the support arm 600 by rotation of the driven sprocket wheel 500 ) together, as shown in FIG. 6B , the water collecting unit 700 moves faster than the speed at which the gate 100 is opened. Through this, it is possible to prevent the sludge falling downward through between the open gates 100 from falling into the water supply unit 700 .

Next, as shown in Fig. 6c, hydraulic pressure is continuously supplied to the driving cylinder unit 220 through the hydraulic and pneumatic supply unit 250 so that the cylinder rod 240 is completely inserted into the driving cylinder unit 220 and At the same time, each gate 100 provided on both sides of the sludge outlet 120 rotates completely from the inside to the outside of the sludge outlet 120 so that the sludge outlet 120 is kept fully open, so the cake hopper body 110 After all of the sludge temporarily stored in the sludge is discharged to the loading box of the vehicle through the sludge discharge port 120, the gate 100 is closed through the reverse process as described above, and the water collecting unit 700 is located in the lower part between the gates 100. can be positioned.
