Description

Apparatus for removing suspended solids

The present invention relates to a float removal apparatus, and more particularly, to a float removal apparatus capable of automatically removing the float in an optimal state regardless of the change in the water level by automatically moving the discharge means up and down in accordance with the change in the water level. .

In general, tap water is generated when the raw water introduced into the intake through the water tunnel of the dam is subjected to water treatment in mixed, flocculated, sedimentary, filter and purified water.

During the treatment process, the mixed paper reacts with contaminants and flocculant in the raw water within a short time to generate flocs by electric neutralization and adsorption.In the flocculated paper, larger and densely matured settleable or Filterable flocs are generated.

This water purification process requires the removal of the floc produced in the mixed or flocculated paper, that is, the scum or suspended matter floating on the water and sludge settling into the water.

The sludge settled into the water is treated through a separate treatment device, and the float floating on the water is treated by the worker with a float or buoy float remover.

However, it is difficult to remove suspended solids by manpower at all times, so that the suspended solids are attached or re-precipitated at the end of the flowing water, polluting the water purification environment, and there is a risk of safety accidents when working. In particular, suspended solids that have not been removed by attraction have the problem of providing visual disgust and distrust for tap water.

An example of a conventional float removal apparatus used for such a float removal operation has been disclosed in Korean Registered Utility Model No. 0245299.

The floating material removing device disclosed in Korean Utility Model Registration No. 0245299 has a rectangular cylinder shape of which an upper portion is opened and a discharge port is formed at a lower portion thereof, as shown in FIG. 1, and is fixed to the center of the collecting vessel 10. The operating lever 11, the guide lever 20, which are inserted into the sliding lever 1 and inclined into the sedimentation basin 1, and both sides of the collection container 10 are rotatably coupled to the transfer hole. It consists of a structure having a coupler, and a handle for moving the transfer port up and down.

However, such a float removal device has to be inclined by the operator operating the operation lever to collect the float, there is a problem that can not effectively cope when the water level fluctuates above or below the collector.

Therefore, there is a need for a new structure for removing suspended solids that can solve the above problems.

The present invention was created in view of the above necessity, and provides an improved float removal device for automatically removing the float in an optimal state regardless of the level change by automatically moving the discharge means up and down according to the change of the water level. It is for that purpose.

The predetermined interval h is preferably greater than the depth at which the float is submerged in water.

Thus, the inlet plate 133 of the discharge hopper 132 is located slightly below the depth that the submerged water is submerged in the water surface, the float can be effectively collected into the discharge hopper 132. The predetermined interval h may be appropriately adjusted according to the type of suspended solids and the amount of suspended solids.

The following describes a float discharge process using a float removal device according to an embodiment of the present invention.

6 is a view for explaining the operation of the float removal apparatus according to an embodiment of the present invention.

Referring to the drawings, first, if the water level is constant because the inflow of water is constant, the water level sensor 140 is located on the water surface, the inlet plate 133 of the discharge hopper 132 is slightly below the water surface, that is, a predetermined interval from the water surface By (h) below. Therefore, the float floating on the surface of the flowing water is easily drawn into the inlet plate 133 and collected in the discharge hopper 132, and discharged along the discharge pipe 136 connected to the lower end of the discharge hopper 132.

When the water level increases due to the inflow of water such as precipitation, the water level sensor 140 is located below the water surface. The controller 150 drives the electric motor 110 according to the detection signal received from the water level sensor 140 (hereinafter referred to as 'forward rotation') to move the discharge means 130 upward. At this time, the corrugated pipe 138 is extended upward to minimize the resistance of the discharge pipe 136 to the upward motion of the discharge means (130).

When the water level is reduced due to the outflow of water such as drought, the water level sensor 140 is located on the water surface. The controller 150 drives the electric motor 110 in the opposite direction to the forward rotation (hereinafter referred to as 'reverse rotation') according to the detection signal received from the water level sensor 140 to move the discharge means 130 downward. At this time, the corrugated pipe 138 is contracted downward.

When the water level increases or decreases, the water level sensor 140 transmits a detection signal to the control unit 150 until it is located on the water surface, and the control unit 150 controls the electric motor 110 according to the detection signal, Irrespective of the fluctuations, the discharge means 130 may effectively discharge the suspended matter on the water surface.

7 is a view showing a suspended matter removing apparatus according to another embodiment of the present invention. Float removal apparatus according to another embodiment of the present invention is different in the structure of the float removal device and the water level sensor described in Figures 2 to 6 and the other components are the same.

The water level sensor 140 is coupled to one end of the sensor buoyancy cylinder 142, the sensor buoyancy cylinder 142 floating on the water surface, the sensor rod 144, the sensing unit 145 is installed on the other end of the sensor 145 It may be an assembly sensor configured to include a lower proximity sensor 149 and an upper proximity sensor 148 and a support 146 to detect the approach.

Sensor rod 144 is preferably installed on the support 146 to move up and down by the movement of the sensor buoyancy cylinder 142 according to the change in water level.

When the sensing unit 145 installed on the sensor rod 144 approaches the proximity sensors 148 and 149 by moving the sensor rod 144 upward and downward, the proximity sensors 148 and 149 detect this and notify the control unit 150. 150 drives the electric motor 110 to move the discharge means 130 up and down.

In other words, the sensor buoyancy tube 142 of the water level sensor 140 when the discharge means 130 is placed on the surface of the water and the water level is reduced due to the outflow of water such as drought or the like without the float removal device 100 being operated. ) Is located above the surface of the water.

At this time, the sensing unit 145 is in a state of approaching the downward proximity sensor 149, and the downward proximity sensor 149 notifies the control unit 150. When the controller 150 receives a signal from the downward proximity sensor 149, the controller 150 rotates the electric motor 110 to move the discharge means 130 downward. The driving of the motor 110 may be maintained until a detection signal is not received from the downward proximity sensor 149.

In addition, when the discharge means 130 is located under the water surface due to an increase in the water level, the sensor buoyancy cylinder 142 of the water level sensor 140 is moved upwards by receiving a constant buoyancy in the state of being submerged in water. The unit 145 is in a state of approaching the upper proximity sensor 148, the upper proximity sensor 148 notifies the control unit 150.

When the controller 150 receives a signal from the upper proximity sensor 148, the controller 150 rotates the electric motor 110 to move the discharge means 130 upward. As a result, the discharge means 130 can effectively discharge the suspended matter on the water surface regardless of the change in the water level.
