Abstract

The present invention relates to a device for removing suspended solids (bubbles, scums) floating on the water surface of a chemical mixed paper, sedimentation basin or flocculation basin in a water purification plant or sewage treatment plant. The collecting hopper 22 connected uniaxially with the shaft 20 is operated by lifting up and down at a fixed position without being rotated, and driving the screw jack 10 to remove the floating material so as to sense the position of the buoyancy sensor 40. The collection hopper 22 is lowered until the floating material on the water flows into the collecting hopper 22 and is discharged. After the removal of the floating material is completed, the screw jack 10 is driven to raise the collection hopper 22 to an appropriate position to introduce water. To block. This operation is repeated by setting the timer to remove the float on the surface of the water.

Also. When the float is removed, the buoyancy sensor 40 detects the water level fluctuation so that the position of the collecting hopper 22 is always set at a constant height regardless of the water level change, and by the intermittent driving of the screw jack 10 by a timer. The loss of treated water required to remove the suspended matter in the collection hopper 22 was restrained as much as possible, and the removal of the suspended matter was performed in the entire range by using the collection hopper 22 as a circle.

The way in which the suspended solids are discharged along the drainage pipe can be selected according to the environmental requirements, either natural or forced discharge (self-priming, vacuum pump or submersible pump). In addition, there is no manpower consumption due to automatic operation by timer and simple maintenance.

In mixed or sedimentation or sedimentation sites of water treatment plants or sewage treatment plants, suspended solids (bubbles and scums) are generated by reactions with foreign substances and chemicals in water, and it is essential to remove them. There are various equipments for removing floating water on the surface of water purification plant or sewage treatment plant. There is a lot of water consumption, the amount of water discharged with the float is a lot of water reprocessing cost to reprocess it is a problem. In addition, in the case of the manual and buoyant type, an operating agent is required, and in the case of the electric float remover, a problem arises in that the floating matter is not removed when the motor breaks down.

In order to compensate for the above problems, various kinds of float removers have been made, but the efficiency is low, and the situation is still developing products that can reduce the consumption of water due to removing the floats.

The present invention is to solve the problems of the prior art as described above

The driving unit of the automatic float remover is driven by the screw jack 10 by the operation of the geared motor 11 of one axis, and the screw jack 10 is driven by the operation of the manual handle 12 on the side of the opposite shaft, so that the manual operation is performed even when the motor breaks down. Operation by the handle 12 is made possible.

When the floating material is removed, the connection pipe 21 and the collection hopper 22 connected uniaxially with the screw nut 20 on the outer side of the screw jack 10 as the driving unit are lowered in position without rotating, and the connection pipe is lowered. The sensor bracket 23 fixed to the 21 and the buoyancy sensor 40 mounted thereon lower the collection hopper 22 to the detection position of the water so that the floats on the water flow into the collection hopper 22 and are discharged. After removing the suspended matter, the screw jack 10 is driven to raise the collection hopper 22 to an appropriate position to block the inflow of water. Such operation is reduced by the intermittent repetitive operation by a timer to reduce the loss of treated water. To maximize the removal efficiency of suspended solids.

As such, the present invention aims to reduce the consumption of water in removing suspended solids and to improve the efficiency of removing the suspended solids.

In the present invention, as shown in FIG. 2, the support 30 is installed on the ground to fix the screw jack 10, the upper part of which is the driving part, and the screw jack 10, which is the driving part, is a single-axis geared motor 11. Alternatively, the connection pipe 21 is driven by the power of the manual handle 12 of the opposite shaft, and is connected to the outer side of the screw nut 20 with one screw as the lead distance of the screw as the screw shaft rotates. The collecting hopper 22 does not rotate and moves up and down at a fixed position, and the lowering of the collecting hopper 8 is a sensor bracket 23 fixed to the connecting pipe 21 and a buoyancy sensor 40 mounted thereto. ) Is configured to lower the collecting hopper 22 to the detection position of the water, the sleeve pipe 24 is attached to the lower portion of the cone of the collecting hopper 22 and the sleeve housing 50 so that the up and down is smooth and there is no shaking This serves as a guide. The collection hopper 22 has a circular shape so that floating matters can be removed in the whole range, and the discharge pipe 52 is installed at the lower portion of the sleeve housing 50 and the connecting flange 51, and is fixed to the lower portion of the support 30. .

The method of discharging the suspended matter along the discharge pipe can be selected according to the environmental requirements among natural oil discharge and forced discharge (self-priming, vacuum pump or submersible pump), and automatic and manual operation by timer is enabled.

Unlike other automatic floaters, the present invention has a very simple structure and is simple to install. There is little limitation of the installation space due to the small volume.

The amount of water consumed when removing floats due to intermittent movement is attached by attaching a buoyant sensor with simple structure that can sense the change of water level while reducing unnecessary power consumption in movement operated by intermittent operation by timer. Can be significantly reduced.

In addition, it is possible to cope with unexpected situations because the automatic operation and manual operation are combined, and can be operated manually in an emergency.
