Description

Flushing device for water inlet tank of secondary sedimentation tank

Technical Field

The utility model relates to an environmental protection technology field especially relates to a two sink pond intake chambers washing unit.

Background

The secondary sedimentation tank of a common sewage treatment plant is typical radial inflow peripheral water inlet, the sedimentation tank with scaling of outlet water of a peripheral single weir is provided, the inlet water is completed by a rectangular groove, the scum collecting tank at the tail end of the inlet tank is not ideal, so that a large amount of floating foam is formed on the surface of the secondary sedimentation tank and accumulated on the liquid level, the outlet water quality is seriously influenced, through calculation and field measurement, the difference of the water flow speed at the inlet of the inlet tank and the tail end is large, along with the reduction of the flow rate, a large amount of floating foam carried in sewage, fine oil drops, the inactivated sludge continuously floats upwards, the aggregation is finally pushed to the tail end of the inlet tank, and a.

Secondly, the cleaning of its thick foam only needs to lean on cleaning daily as the owner, but often appears cleaning the frequency and can't follow the production volume, causes the abluent working strength of staff big effect not obvious, and the staff heatstroke very easily appears in summer, goes out the water weir plate and is the triangle-shaped moreover, and is sharp-pointed and sharp, also skids easily on the freezing cell body in winter, brings very big potential safety hazard for the staff, does not solve above-mentioned problem and provides this design two heavy pond intake chamber washing units.

Disclosure of Invention

The utility model aims to overcome the not enough of prior art, adapt to the actual needs, provide a two heavy pond intake chamber washing unit.

The device comprises a water inlet tank, a water outlet tank, a clean water tank and a water spraying pipe, wherein the clean water tank is circular, the water outlet tank is arranged on the outer side of the clean water tank, the water inlet tank is arranged on the outer side of the water outlet tank, the water inlet tank is gradually reduced, the diameter of the water inlet tank is reduced from head to tail in a spiral line mode, and sewage enters the device through the water inlet tank.

The intake chamber is the heliciform and coils and crouches in go out the intake chamber outside, the intake chamber topmost bottom forms the difference in height with the intake chamber bottommost bottom and is 0.6 meters, can make intake chamber entrance current velocity and terminal current velocity difference reduce through this difference in height that sets up make the velocity of flow more even, because the foam that the difference in velocity of flow is too big and produce when having reduced rivers leads to unable and water separation.

The spray pipe is fixed on the inner side wall of the water inlet tank through a connecting piece, one end of the spray pipe is closed, the other end of the spray pipe is connected with the water outlet end of the water pump, the water pump is arranged in the water outlet tank, the water inlet end of the water pump is arranged in the clean water tank, and the spray pipe can spray clean water to remove viscous foam on the water surface.

Two heavy pond intake chamber washing unit, still including set up in hole for water spraying on the spray pipe wall, the spray pipe is 45 settings with vertical direction down, and the scope of can spraying through hole for water spraying and 45 settings of vertical direction is bigger, and is better to gluing thick foam cleaning effect.

The beneficial effects of the utility model reside in that:

this difference in height through setting up can make intake antrum entrance velocity of water and terminal velocity of water difference reduce and make the velocity of flow more even, because the velocity of water is poor too big and the foam that produces when having reduced rivers, lead to unable and separation of water, secondly, through setting up the water jet on the spray pipe for but spraying range is bigger, and is better to gluing thick foam clearance effect, has reduced staff's working strength, guarantees that the index of going out water is in emission standard.

Detailed Description

The invention will be further described with reference to the following figures and examples:

example 1: a secondary sedimentation tank water inlet tank flushing device, which is shown in figure 1-2.

Including intake chamber 1, play basin 2, clear water tank 8 and spray pipe 4, clear water tank 8 is circular, and its outside is equipped with out basin 2, it is equipped with intake chamber 1 to go out the basin 2 outside, intake chamber 1 is the reducing gradually, and its diameter is the helix in proper order from head to tail and reduces, and sewage by intake chamber 1 gets into this device.

Intake chamber 1 is the heliciform and rolls up in go out the 2 outsides of intake chamber, 1 top bottom of intake chamber and 1 bottom of intake chamber form the difference in height to be 0.6 meters, can make 1 entrance water velocity of intake chamber and terminal water velocity difference reduce through this difference in height that sets up make the velocity of flow more even, because the too big foam that produces of water velocity difference when having reduced rivers leads to unable and the separation of water.

The spray pipe 4 is fixed on the inner side wall of the water inlet groove 1 through the connecting piece 3, one end of the spray pipe is closed, the other end of the spray pipe is connected with a water outlet end 5 of the water pump 6, the water pump 6 is arranged in the water outlet groove 2, a water inlet end 7 of the water pump 6 is arranged in the clear water tank 8, clear water can be sprayed out through the arranged spray pipe 4, and viscous foam on the water surface is removed.

Two 1 washing unit of heavy pond intake chamber still including set up in hole for water spraying 401 on the 4 pipe walls of spray pipe, 4 settings 45 with vertical direction are down of spray pipe, and it is bigger with 45 settings of vertical direction to spray the scope of can spraying through hole for water spraying 401, and is better to gluing thick foam cleaning effect.

In particular use: water is got into by inlet channel 1 high-end department, because gravity and the effect of resistance, ordinary constant diameter groove waste water velocity of flow can be littleer and smaller, its high-end and low end velocity difference are bigger and bigger, consequently can produce a large amount of thick foams, and because its diameter of inlet channel 1 of this design is the setting that the helix reduces from head to tail in proper order, its in-process that flows, its velocity of flow is faster for the rivers cross section is less, the defect that the velocity of flow reduces when having remedied the constant diameter, the production of the thick foam of part has been reduced.

Furthermore, end 7 introduces the clear water of intaking through water pump 6, the suction through water pump 6 gets into in the spray pipe 4, because the hole for water spraying 401 that sets up on the spray pipe 4, the clear water sprays straight basin 1 surface through hole for water spraying 401, surface of water foam and superficial mud are destroyed and are sunk to the bottom, the surface of water is limpid, and then viscous foam has been eliminated, the liquid level velocity of flow has been increased again, deposit with higher speed in order to reach the purpose that solid-liquid separation eliminated the foam, staff's working strength's effect has been reduced, guarantee the purpose of play water index in discharging the standard vertebra.

In addition, a water flow baffle plate can be arranged at the lower end of the water inlet tank 7 every 5 m, so that the flow speed of the sewage is continuously changed in the forward propelling process, the formed foam is continuously dissolved, the purposes of reducing the generation and aggregation of the foam are achieved, and the effect of assisting in reducing the foam is further achieved.

The embodiment of the present invention discloses a preferred embodiment, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention according to the above embodiment, and make different extensions and changes, but do not depart from the spirit of the present invention, all of which are within the protection scope of the present invention.
