Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum suction type sludge collecting device,

The present invention relates to a vacuum suction type sludge collecting device and a vehicle equipped with the vacuum suction type sludge collecting device, and is capable of sucking a large amount of sludge by the function of a vacuum pump using the entire chamber in the service tank and discharging the sludge quickly by an air compressor The efficiency of the water treatment process is increased. If the additional suction line is connected to the heat exchanger, the single sludge in the settling tank can be effectively sucked and discharged by using a single service tank. And is easy to install even in a narrow space, and a vehicle equipped with the vacuum suction type sludge collecting device.

Generally, the sludge treatment is performed by combining various processes such as concentration, digestion, dehydration, incineration, and melting. In sludge treatment, if the total amount of sludge separated from the water treatment facility can be made, it will be made into a form which is easy to handle quickly before decaying, and at the same time, it will be given necessary properties for the resource recovery.

In the sludge treatment, the sludge transfer facility is composed of a sludge withdrawal facility, a transfer pipe, and a storage facility. When the water treatment facility and the sludge treatment facility are installed in the same site, the transfer of the sludge is relatively short. The sludge generated in a plurality of treatment plants is concentrated in one place, or in the case where the water treatment facility and the sludge treatment facility are separated from each other, long-distance transportation is performed. Sludge piping is often terminated as a single line in the case of a short distance, but the second line is ideal because of the risk of unforeseen situations occurring during pipeline transport in case of long distance. In this case, it is possible to increase the safety of transportation by installing the communication pipe in each route. It is important to sufficiently communicate with each other about the amount of conveyance and the characteristics of the sludge between the conveying side and the conveying side when actually conveying the sludge. In case of long-distance transfer, high concentration of solids in the sludge should be taken into consideration, since it is likely to cause problems such as pressure loss or pipe closure due to an increase in the viscosity and the decay of the water due to the longer maturation time during transportation.

The sludge treatment facility consists mainly of a sludge pump, a transfer pipe, and a sludge tank. The sludge pump should not be blocked by the obstruction.

Korean Patent No. 10-0680116 (a sludge supply apparatus using a plurality of pumps) has been proposed as a background of the present invention. This allows sludge supplied from the tank to be supplied to the inside of the filter press more effectively by using the low pressure pump and the high pressure pump at the same time, thereby maximizing the transfer amount of the sludge to maximize the efficiency of the operation. The sludge tank is connected to a separating and discharging pipe having a predetermined diameter between the sludge tank and the filter press. The sludge tank is connected to a separating and discharging pipe having a predetermined diameter sikidoe form a sludge supply means of low-pressure pump and the high-pressure pump to each of the low pressure pump maintains the pressure of 3~5kg / cm ² as well as the high-pressure pump the sludge in the filter condition of maintaining the pressure of 7~12kg / cm ² And is continuously supplied to the filter plate of the press.

However, the background art uses the pressure generated by the simultaneous operation of the low-pressure pump and the high-pressure pump to overcome the limit of the transfer amount, but the volume of the pump is limited and it is difficult to transfer the large-capacity sludge.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

The vacuum suction type sludge collecting apparatus according to the present invention is provided with a service tank 12 capable of repeatedly performing vacuum suction (sludge suction) and air compression (sludge discharge) as shown in FIG.

2, the service tank 12 has a lower side sludge chamber 122 divided by a membrane 121 and an upper side operation chamber 123. A suction valve 124 and a discharge valve 125 are connected to the sludge chamber 122 side and a negative pressure valve 126 and a pressure valve 127 are connected to the operation chamber 123 side. The service tank 12 may be constructed by assembling a tank which is divided to have a sludge chamber 122 and an operation chamber 123. The periphery of the membrane 121 is attached to the divided bonding surfaces of the service tank 12. The membrane 121 is made of a flexible membrane material and can be freely reversed by suction and compression.

Here, the negative pressure valve 126 may be connected to the servo motor S to control the suction speed, and may be operated under the control of the controller 30. Further, the suction valve 124, the discharge valve 125 and the pressure valve 127 are constituted of a motor-operated valve type having a motor M.

The service tank 12 is provided with a position sensor 19 for detecting the top dead center position of the membrane 121. The position sensor 19 sends the sensed signal to the control unit 30. [

One end of the sedimentation tank suction pipe 14 is connected to the suction valve 124 side. The other end of the sedimentation tank suction line 14 is connected to the sludge settling tank 5. At this time, the other end of the suction pipe 14 may be provided with a strainer 170. The suction pipe 14 may be additionally provided in a plurality of units connected in parallel.

The sedimentation tank suction line 14 is provided with a sedimentation tank opening / closing valve 16 for controlling the opening and closing amount of the pipeline and the suction amount. Therefore, when a suction force is generated in the sludge chamber 122 when the sedimentation tank opening / closing valve 16 and the suction valve 124 are opened, the sludge collected in the sedimentation tank 5 is sucked into the service tank 12 as shown in FIG.

A vacuum pump 18 is connected to the negative pressure valve 126 side. The vacuum pump 18 generates a negative pressure (vacuum pressure) in the operation chamber 123 and expands the sludge chamber 122 by inverting the membrane 121 toward the operation chamber 123 side. A suction force is generated on the side of the settling tank suction pipe 14 as the sludge chamber 122 expands.

The air compressor (20) is connected to the side of the pressure regulating valve (127). 3, the air compressor 20 supplies the compressed compressed air to the operation chamber 123, inverts the membrane 121 toward the sludge chamber 122, and discharges the sludge sucked into the service tank 12.

A sludge storage tank 22 is connected to the discharge valve 125 side. The sludge storage tank 22 increases the concentration of the solid matter by solid-liquid separation of surplus and raw sludge, thereby reducing the volume and reducing the load of the subsequent treatment process.

The sludge storage tank 22 is provided with a water level sensor 24 for measuring the level of the introduced sludge and controlling the air compressor 20 and the vacuum pump 18 at the same time. The water level sensor 24 is electrically connected to the control unit 30. [ Accordingly, the signal of the sensed water level measured by the water level sensor 24 is sent to the control unit 30.

The control unit 30 controls the suction valve 124, the discharge valve 125, the negative pressure valve 126, the pressure valve 127, and the like in accordance with the suction and discharge of the sludge.

Meanwhile, in the present invention, a sediment suction line path 15 connected to the sedimentation tank suction line 14 in parallel with each other may be further connected to the suction valve 124 side. At this time, a valve 17 is provided as a bogie suction pipe for adjusting the opening and closing amount of the duct and the suction amount. At least one suction bell pipe for bogie 151 is connected to the bogie suction pipe 15 for sucking collected sludge into the sludge collecting bogie 100.

Therefore, when the valve 17 is opened to the sludge collecting tank 100 and the suction force is generated in the sludge chamber 122 of the service tank 12 while the corrugated pipe 151 is connected to the sludge collecting carriage 100, ) Is sucked into the service tank (12).

The operation of the vacuum suction type sludge collecting apparatus constructed as described above will be described.

First, the process of transferring the sludge in a state in which the vacuum pump 18 and the air compressor 20 are driven in a state where the valve 17 is closed by the valve suction pipe will be described. At this time, as shown in Table 1, the service tank 12 is pumped while controlling the respective valves while repeating mode 1 (suction) and mode 2 (discharge).

O: Closed, X: Open  The settling valve (16) The suction valve 124, The discharge valve 125, The pressurization valve (127) The negative pressure valve (126) Valves (17)  Mode 1     ○     ○     ×     ×     ○     ×  Mode 2     ○     ×     ○     ○     ×     ×  Mode 3     ×     ○     ×     ×     ○     ○  Mode 4     ×     ×     ○     ○     ×     ○

The control unit 30 opens the suction valve 124 and the negative pressure valve 126 and closes the discharge valve 125 and the pressure valve 127 as in the mode 1.

2, a negative pressure is generated in the operation chamber 123, the membrane 121 is inverted upward, the sludge chamber 122 is expanded, a suction force is generated in the sludge chamber 122, and the sludge in the settling tank 5 And then sucked into the service tank 12 after passing through the settling tank suction line 14.

 When the membrane 121 reaches the maximum, the position sensor 19 senses it, and the control unit 30 proceeds to mode 2 by the sensing signal.

The discharge valve 125 and the pressure valve 127 are opened and the suction valve 124 and the negative pressure valve 126 are closed at this time. Accordingly, the compressed air compressed in the air compressor 20 through the pressure valve 127 flows into the operation chamber 123 of the service tank 12 as shown in FIG. 3, so that the membrane 121 is reversed downward again The volume of the sludge chamber 122 is reduced and the sludge filled in the service tank 12 is quickly transferred to the sludge storage tank 22 through the discharge valve 125.

The vacuum suction type sludge collecting apparatus as described above repeatedly performs modes 1 and 2 to suck sludge into the large-capacity sludge chamber 122 of the service tank 12 and discharge the sludge into the sludge storage tank 22. The control unit 30 stops the vacuum pump 18 and the air compressor 20 when the position of the sludge in the sludge storage tank 22 is fully filled up by the water level sensor 24. [

Here, the judgment of switching from the mode 2 to the mode 1 can be made by the control unit 30 by controlling the time. Therefore, the sludge can be quickly transferred from the settling tank 5 (or the treatment plant) to the sludge storage tank 22, thereby increasing the water treatment efficiency and shortening the water retention time during the transfer to prevent the progress of decay, It is possible to prevent the occurrence of problems such as closure.

The mode 3 (suction) and the mode 4 (discharge) are repeated so that the sludge loaded on the carriage 100 is directly conveyed to the sludge storage tank 22 . This is done by controlling each valve in the modes 3 and 4 as shown in Table 1.

4, the sub compressor 201 may be connected to the air compressor 20 in a parallel manner for boost compression. The sub-compressor 201 may be used to increase the discharge pressure of the sludge chamber 122 to a smaller capacity than the air compressor 20. At this time, it is preferable that a check valve 202 is installed on the outlet side of the air compressor 20 and the sub compressor 201.

Further, the sub-vacuum pump 181 may be further connected to the vacuum pump 18 in parallel to increase the negative pressure (increase the suction force). Therefore, when the sub vacuum pump 201 is driven together, the vacuum pressure in the operation chamber 123 of the service tank 12 increases and the suction force of the sludge in the sludge chamber 122 rises.

Here, by controlling the servo motor S of the negative pressure valve 126, the vacuum pressure of the operation chamber 123 in the service tank 12 can be controlled, and the suction speed of the sludge can be controlled.

On the other hand, the present invention can be constructed by mounting the above-described vacuum suction sludge collecting device on the vehicle 1000 (for example, a trailer) as shown in Figs. That is, the present invention can provide a vehicle equipped with a vacuum inhalation sludge collecting device. At this time, the sludge storage tank 22 is excluded from the mounting of the vehicle.

As shown in FIG. 5, when the vacuum suction type sludge collecting device is mounted on a vehicle, the system moves to a sludge disposal plant at a designated location as well as another treatment plant, thereby constituting a system capable of transferring the sludge to a separate transportation vehicle.

The same control unit 30 for controlling the suction valve 124, the discharge valve 125, the negative pressure valve 126 and the pressure valve 127 is mounted on the vehicle.

As shown in Fig. 1, the vehicle 1000 is provided with a cargo intake pipe line 15 connected to the settling tank suction pipe line 14 in parallel to each other on the suction valve 124 side and a cargo suction pipe line 15 connected to the cargo suction pipe line 15 for opening / The valve 17 can be equally installed with the valve-moving suction pipe to be regulated. Then, the bogie intake bell pipe 151 to be connected to the bogie intake pipe passage 15 can be further mounted on the vehicle.

2 and 3, the service tank 12 may further include a position sensor 19 electrically connected to the control unit 30 to sense a position of top dead center of the membrane 121.

At this time, the control unit 30 can control the operation time of the vacuum pump 18 and the air compressor 20 to determine the amount of sludge to be supplied to the storage tank of the transportation vehicle (not shown).

The suction and discharge processes of the sludge due to the negative pressure and air compression occurring in the service tank 12 after the vacuum suction type sludge collecting device is mounted on the vehicle 1000 are as described above and will not be described here.

Here, the vacuum pump 18 and the air compressor 20 can be driven by receiving power from the PTO power unit 1200 of the vehicle 1000 as shown in FIG. The PTO power unit 1200 is constituted of a hydraulic pump 1210 interlocked with the engine E-side transmission 1210 and a hydraulic motor 1220 driven by pressure oil of the hydraulic pump 1210.

In the case of the vehicle 1000 equipped with the vacuum suction type sludge collecting device, the sludge or wastewater can be transported to the transportation site quickly by moving to the place where the sludge or wastewater is generated or the collected place, and the water treatment time can be shortened.
