a floating ball type scum siphon collector comprises a floating ball device, a flow guide siphon pipe, a scum collecting well, a scum isolating net and a scum discharging pipe, wherein the scum collecting well is positioned outside a structure to be cleaned and is lower than the water level in the structure; a scum separation net is arranged in the scum collecting well and divides the scum collecting well into a scum area and an overflow area, the scum area is provided with a scum pipe, and the overflow area is provided with a drain pipe; a diversion siphon pipe extends from the water surface of the structure to be cleaned to the lower part of the scum isolation net in the scum collecting well, namely an outlet of the diversion siphon pipe is positioned in the scum area; the water level of the scum collecting well is kept higher than the siphon outlet of the draft tube; the inlet of the diversion siphon is connected with the floating ball device, so that the inlet is kept to be submerged by the water surface in the structure to be cleaned; the diversion siphon is also provided with a manual gate valve and an air suction cylinder. The utility model discloses in, the honeycomb duct pipe diameter is 100 ~ 125 mm.

In the utility model, a valve is arranged on the slag discharge pipe.

The utility model discloses an adjust the floater, make this system can float in the surface of water, collect the well through honeycomb duct and dross and link to each other, install manual gate valve and manual pump bowl on the honeycomb duct, the water level mark height of well is collected to the dross is far less than the water level in the sedimentation tank, after the equipment fixing, through the inside residual air of manual pump bowl with the honeycomb duct, make the inside vacuum that forms of honeycomb duct (the honeycomb duct both ends all are located below the surface of water), utilize the siphon principle, make sedimentation tank surface dross can stay oneself and get into dross collecting well, supernatant overflow to factory sewage pipe after the sedimentation separation, dross is regularly arranged to the concentrated pond of mud through the evacuation pipe.

The floating ball device is used for adjusting the buoyancy of the whole set of equipment and adapting to a floating ball with a corresponding size according to the total weight of the equipment.

The device is used for collecting floating slag on the water surface of structures such as a sedimentation tank of a sewage treatment plant and the like, and has the following beneficial effects compared with the prior art: (1) compared with manual periodical cleaning and fishing, the total phosphorus release can be reduced, the labor is liberated, and a better cleaning effect is achieved; (2) compared with surface slag scraping equipment, the device is simple, convenient and energy-saving. (3) The civil engineering that need get rid of the dross structure need not be reformed transform, only need increase this patent equipment can.

Detailed Description

The invention relates to a floating ball type scum siphon collector for water treatment, which has the characteristics of energy consumption saving, obvious effect and manpower reduction.

As shown in fig. 1 and 2, the structure 10 is a structure (mostly a sedimentation tank in a sewage treatment process) for removing scum, and is generally a steel-concrete structure tank body; the floating ball device 11 is used for providing buoyancy for the patent system, the material and the size of the floating ball device are selected according to the overall weight of the patent system, and the floating ball device aims to ensure that the inlet 12 of the guide pipe is just submerged by the water surface and is below the water surface or slightly lower than the water surface (1-2 cm below the water surface), so that floating slag on the water surface can quickly and orderly enter the guide pipe through the water inlet; the position of the draft tube inlet 12 is just submerged or slightly lower than the water surface, so that scum can be discharged as far as possible; the diversion siphon 13 is key equipment of the patent, the pipe diameter is generally 100-125 mm, the diversion siphon can be finely adjusted according to the size of an inlet, and two ports of the diversion siphon are required to be below the water surface so as to ensure the vacuum condition in the siphon; a manual gate valve 14 for controlling the operation of the system; the manual air pump is used for discharging redundant air in the diversion siphon 13 to ensure vacuum in the tube; the structure 16 is a scum collecting well, and the water level of the scum collecting well is lower than the normal water level of the structure 10, so that the normal operation of a siphon system is ensured; the device 17 is a scum isolation net and is used for filtering scum to enable the scum to stay at the lower part of the collecting well; when the amount of scum in the collecting well is large, the scum is discharged through a scum pipe 18, so that the filtering effect is ensured; after being filtered by the collecting well, the supernatant is discharged through a water outlet pipe 19; in fig. 2, the float anchor 20 is used to estimate the position of the float; at least two connecting rods 22 are arranged on the connecting ring 21, the included angle between every two connecting rods is the same, one end of each connecting rod 22 is connected with the connecting ring 21, and the other end of each connecting rod is connected with the floating ball hoop 20, so that the position of the floating ball can be fixed, and the balance effect is achieved.

The operation steps of the system are as follows:

1. installing the equipment in place, selecting a corresponding floating ball system according to the weight of the equipment, wherein a water inlet is just 1-2 cm below the water surface, and the equipment is ready;

2. opening a manual gate valve 14, closing a gate valve of a deslagging pipe 18, pumping air in the pipeline through a manual air pumping barrel 15 to form vacuum, wherein the whole system meets the siphon condition, and scum on the water surface in the structure 10 enters a scum collecting well 16 together with water from an inlet 12 through a diversion siphon 13;

3. a scum separation net 17 is designed in the scum collecting well 16, the outlet of the diversion siphon 13 is positioned below the scum separation net 17, scum is separated, and supernatant is discharged through a weir and flows to a sewage pipe network along a drain pipe 19;

4. when the scum is accumulated to a certain amount, the scum can be discharged through the scum pipe 18 or is considered to be cleaned;

5. when the surface scum is cleaned, the system is required to stop working, and the system can be shut down by closing the manual gate valve 14.

After the device is started, the surface scum in the structure 10 continuously enters a scum collecting well along with a water flow source through the flow guide pipe, supernatant is discharged, and the scum is trapped by the separation net and then is periodically discharged.
