Description
Technical field
The utility model is about a kind of sewage-treatment plant, relates in particular to a kind of sewage disposal second pond scum silica frost cleaning plant.
Background technology
When sewage treatment plant moves, second pond produces scum silica frost, the scum silica frost that it mainly produces from scum silica frost and the nitrated rear mud floating of second pond activated sludge of biochemical system, and this is recurrent in sewage disposal work; If cleaning not in time not only affects second pond attractive in appearance, and scum silica frost too much can produce toxin and affects draining water quality.Although existing second pond equipment is designed with the devices such as debris retaining plate, slag trap, (wherein, debris retaining plate is arranged on second pond water outlet edge, is equally circular structure with second pond; Slag trap is arranged on rotation mud scraper trestle below, the structure of straight plate shape), but remove not thorough, only have the scum silica frost at close second pond edge to be eliminated, lean on paracentral scum silica frost because the water surface rotates under the effect of second pond rotation mud scraper trestle, scum silica frost can't waft near second pond edge debris retaining plate because of the barrier effect of described slag trap, and along with under debris retaining plate and common the stopping of slag trap and enter slag-drip opening, but swim in pond face with the slag trap synchronous rotary of trestle below.In the prior art, scum silica frost needs operating personnel to clear up at any time; Cleaning scum silica frost time and effort consuming, and must be near pool side operation in the time of cleaning, labour intensity is large, has potential safety hazard; If put on life vest, swimming life-buoy is cleared up, and can hinder body activity, very easily fall into pond and cause danger.
Thus, the inventor relies on experience and the practice of being engaged in for many years relevant industries, proposes a kind of sewage disposal second pond scum silica frost cleaning plant, to overcome the defect of prior art.
Utility model content
The purpose of this utility model is to provide a kind of sewage disposal second pond scum silica frost cleaning plant, scum silica frost in second pond effectively can be removed, prevent from occurring when operating personnel from clearing up pond face drowned, alleviate labor intensity of operating staff, make operating personnel do system monitoring work with the more time, be conducive to the operation up to standard of environmental protection equipment highly effective and safe.
The purpose of this utility model is achieved in that a kind of sewage disposal second pond scum silica frost cleaning plant, and described scum silica frost cleaning plant includes the rectangle slag trap that is arranged on the annular debris retaining plate at second pond edge and is arranged on rotation trestle below; Front in rotation trestle rotation direction is provided with an arc scavenging pipeline; The concave side of described arc scavenging pipeline is towards described rotation trestle, and arc scavenging pipeline is provided with multiple nozzles along its concave side; This arc scavenging pipeline one end is connected with the center of rotation of rotation trestle, and the arc scavenging pipeline other end extends and arranges to second pond edge; Described arc scavenging pipeline is connected in a water pump.
In a preferred embodiments of the present utility model, described arc scavenging pipeline is arranged on apart from the position of water surface 20cm, and level is installed.
In a preferred embodiments of the present utility model, described arc scavenging pipeline is 60 ° of angle settings with rotation trestle.
In a preferred embodiments of the present utility model, on described arc scavenging pipeline, evenly interval arranges nine nozzles.
In a preferred embodiments of the present utility model, described nozzle spray angle downwards and the water surface be 30 °.
In a preferred embodiments of the present utility model, the spout of described nozzle is prolate shape.
In a preferred embodiments of the present utility model, described water pump is an immersible pump, and this immersible pump is fixedly installed in the water of rotation trestle below.
From the above mentioned, the utility model sewage disposal second pond scum silica frost cleaning plant, scum silica frost in second pond effectively can be removed, prevent from occurring when operating personnel from clearing up pond face drowned, alleviate labor intensity of operating staff, make operating personnel do system monitoring work with the more time, be conducive to the operation up to standard of environmental protection equipment highly effective and safe.
Accompanying drawing explanation
The following drawings is only intended to the utility model to schematically illustrate and explain, does not limit scope of the present utility model.Wherein:
Fig. 1: be the structural representation of the utility model sewage disposal second pond scum silica frost cleaning plant.
Fig. 2: be the plan structure schematic diagram of Fig. 1.
The specific embodiment
Understand for technical characterictic of the present utility model, object and effect being had more clearly, now contrast accompanying drawing the specific embodiment of the present utility model is described.
As shown in Figure 1 and Figure 2, the utility model proposes a kind of sewage disposal second pond scum silica frost cleaning plant, described scum silica frost cleaning plant includes the annular debris retaining plate 1 that is arranged on second pond edge and the rectangle slag trap 2 that is arranged on rotation trestle 9 belows; Front in rotation trestle 9 rotation directions is provided with an arc scavenging pipeline 3; The concave side of described arc scavenging pipeline 3 is towards described rotation trestle 9, arc scavenging pipeline 3 is provided with multiple nozzles 31 along its concave side, in the present embodiment, on described arc scavenging pipeline 3, evenly interval arranges nine nozzles, the water spraying direction of multiple nozzles and the direction of rotation of rotating trestle 9; These arc scavenging pipeline 3 one end are connected with the center of rotation of rotation trestle 8, and arc scavenging pipeline 3 other ends extend and arrange to second pond edge; Described arc scavenging pipeline 3 is connected in a water pump 4, and in the present embodiment, described water pump 4 is an immersible pump, and this immersible pump is fixedly installed in the water of rotation trestle 9 belows; Get supernatant (top clear water) in second pond and supply with arc scavenging pipeline 3 as purging water source, this immersible pump power is 0.5KW, guarantees that hydraulic pressure maintains 0.5MPa.The pressure that nozzle provides by immersible pump sprays water, because the impulsive force of water forms water curtain, pond face scum silica frost is blowed to slag trap, second pond pond face is done to circumference purge along with trestle rotates, by slag trap, scum silica frost is pushed to second pond slag-drip opening and enter between sludge press filtration and process.
