Description
Technical field
The utility model belongs to sewage disposal machinery technical field, and relate in particular to a kind of sewage work and adopt sequencing batch active sludge to be used to strain equipment except that the supernatant liquor in the reaction tank,
Background technology
The key of straining hydrophone and be in SBR (sequencing batch active sludge) sewage treatment process is established each, be used for getting rid of the primary water of reaction tank, it can change with the lifting of water level gets rid of the primary water on reaction tank surface automatically and continuously and does not stir following heavy mud, thereby guarantees effluent quality.The hydrophone of straining relatively more commonly used now has forms such as Float cylinder type, hydrocone type and mechanical type.Float cylinder type and siphonic decant device simple in structure but strain water depth little, strain water speed and be difficult to regulate; Mechanical type is strained hydrophone price height, energy consumption is big.
The disclosed application number of State Intellectual Property Office is 02264338.9, and name is called the patented technology of " the rotary hydrophone of at the uniform velocity straining of worm drive ", discloses a kind ofly can realize at the uniform velocity straining the device of water along with water level descends.The principal feature of this device is that its water outlet adopts pipeline, strain water pipe and rising pipe be arranged in parallel, flexibly connect by at least one pair of connecting tube, drive unit connects pipe connecting, the swing of driving pipe connecting, thus the water pipe of straining that drives the pipe connecting upper end moves in a circle around water shoot.It rational in infrastructure simple manufactured easily, and cost is low, and is easy for operation, is easy to control and strains sink pipe overflow crest of weir and at the uniform velocity descend, and it is big to strain water depth.But because its pipeline configuration, can not realize that big yield strains water, and drive mechanism since major part to be arranged on water low, maintenance, the inconvenience of fixing a breakdown.
The utility model content
The utility model is at above problem, and a kind of straight-line is provided, and can realize that big yield strains water, and the hydrophone of straining easy to maintenance.
The technical solution of the utility model is: the water outlet place that is arranged on sewage lagoon, it is by the doorframe that is fixed on the water outlet place, form with the journey controller that is connected drive unit with door, the drive unit that moves up and down of driving gate that doorframe is slidingly connected, drive unit is fixedly connected on the pool wall, connects the upper end of door by coupling device; Doorframe is fixedly connected on the pond inwall of water outlet, and its width is slightly larger than the water outlet width, and its upper end is contour with the water outlet upper end, and the height of doorframe is 2 times of door height; The two sides of door are slidingly connected with doorframe respectively, and the height of door is slightly larger than the water outlet height; Upper and lower end at the door moving line is respectively equipped with controller.
Described door top sets out the mouth of a river, and the upper edge of door is fixedly connected with tank, and the tank width is slightly less than the width in pond, and a side of tank is provided with the opening that docks with door top water outlet.
Described bottom of gullet is established the gradient, and opening is located at the bottom land lowest part.
Each side plate upper edge of described tank is a spination.
Described door is connected by leading screw with drive unit.
Described door is connected by pulley, race with doorframe.
Described door is provided with gasket with the bonding surface place of doorframe.
Described gasket is fixedly connected on the doorframe inside casing.
The utility model has changed the form that in the past sets out hose nozzle at bottom land, adopts in the direct water outlet of cell wall, has realized the draining of straight-line big yield; At water outlet doorframe, door body are set, adopt tightness system to realize sealing between the two, can seepage, and easy to maintenance, doorframe stretches into below the water outlet, the stroke that can guarantee, water is reliably strained in realization; Drive unit is located at the groove top, connects the upper end of door, has made things convenient for maintenance equally.Deft design of the present utility model, rational in infrastructure, changed inherent bottom land low discharge discharging mode, realize big flow draining, in conjunction with the actuating speed setting device, can realize that speed change strains water.
