Description

A kind of height slot type greasy dirt floating collection system
Technical field
The present invention relates to greasy dirts to collect treatment technology, and in particular to greasy dirt floating collection method in a kind of height slot.
Background technology
Currently, there are mainly two types of the methods of water-oil separating, one kind is a physically separate, and another kind is Chemical Decomposition, both Method is each advantageous and insufficient.In addition, the greasy dirt that engineering construction scene automobile-washing groove generates, cannot collect separation, Zhi Neng at any time It is accumulated in first stage precipitation tank;Conventional first stage precipitation tank uses fixed overflow port, and when liquid level declines, oil reservoir is excessive not, rain Since automobile-washing groove sedimentation basin topography is relatively low when its rainfall, the rainwater easy short time collects inflow sedimentation basin, causes sedimentation basin greasy dirt Liquid level rising is too fast, and greasy dirt has little time to flow to collecting pit by fixed weir mouth, just rises excessive pollution ground environment from Chi Kou, The conventional frequent manual adjustment moisturizing of sedimentation basin, collecting pit need to send someone to check pump drainage daily;Also, sedimentation basin volume is larger, auxiliary Separator complexity energy consumption is big, inconvenient for use, and cost of investment is high;What is more important, the inefficiency of water-oil separating.Cause How this, design a kind of device and method that grease collects good separating effect, cost-effective greasy dirt collection and detach, become capable The problem of industry overriding concern.
Invention content
It is an object of the present invention in view of the deficiencies of the prior art, a kind of grease is provided and is collected and good separating effect, cost Low height slot type greasy dirt floating collection system.
The technical solution adopted by the present invention is:A kind of height slot type greasy dirt floating collection system includes mainly high slot structure With low slot structure, high slot structure includes high slot substrate, spacing column and receives oil-piping layout, and the spacing column is set to high slot substrate The top of inner cavity, spacing column is arranged with flexure spring, and lower end and the spacing column of flexure spring are fixedly linked, flexure spring Upper end edge spacing column moves up and down;The top for receiving oil-piping layout is equipped with floating receiving port, floating receiving port and flexure spring It is connected;The outlet for receiving oil-piping layout is connected to low slot structure;The low slot structure include low slot substrate, low slot receive oil vessel, Float level meter and drainpipe, the low slot substrate are located at the lower section of high slot substrate, and low slot is received oil vessel and installed in low slot substrate Interior, the top that low slot receives oil vessel offers the oil inlet mouth of a river being connected to receipts oil-piping layout, and the lower part that low slot receives oil vessel offers Discharge outlet, discharge outlet are connected to the entrance of drainpipe;Drain valve is configured on drainpipe;The float level meter is installed in low Slot is received in the middle part of the outer wall of oil vessel, and float level meter is received with low slot and is connected to inside oil vessel, and overflow port is equipped in float level meter, Overflow port is communicated with greasy dirt collecting vessel.
By said program, the outer of the floating receiving port is fixed with floating ball.
By said program, the float level meter includes the floating body cylinder of upper opening, and is built in floating body cylinder The floating body of body, the top of the extended floating body cylinder of upper end beacon body portion of upper floating body;The low slot receive oil vessel with Floating body cylinder is connected to, and the overflow port is opened in the side wall of floating body cylinder, and overflow port is collected by overflow pipe and greasy dirt Bucket connection.
By said program, the drain valve is electric gate valve;The floating collection system further includes infrared facility and logic Circuit controller, infrared facility include face arrangement beam launcher and infrared light sensation collect target, beam launcher to Infrared light sensation collects the infrared beam one and infrared beam two of target emission level;The beam launcher and infrared light sensation are collected Target is located at the top of floating body cylinder, and floating body cylinder is between beam launcher and infrared light sensation collection target;It is described The extended floating body cylinder of upper end beacon portion of floating body blocks infrared beam one or infrared beam two, generates two kinds of signals Source is delivered to logic circuit controller, and logic circuit controller collects target with infrared light sensation respectively and drain valve is connected.
By said program, the receipts oil-piping layout integrally bending is at snakelike.
By said program, the spacing column has three, is distributed in positive triangle.
By said program, the flexure spring in three spacing columns is connected with limiting bracket, is installed on limiting bracket floating Dynamic receiving port.
By said program, the lower end of spacing column is connected by bolt with high slot substrate.
By said program, low slot receives the interior bottom that oil vessel is set to low slot substrate by supporting support, and low slot is received oil and held The top of device is fixedly linked by fixing bracket and the madial wall of low slot substrate.
Beneficial effects of the present invention are:
1, the collection system is designed using height slot, and preliminary water-oil separating is carried out in high slot and is floated to collect, is used in low slot Water-oil separating again solves the problems, such as that greasy dirt carries a large amount of moisture content when water-oil separating in existing collecting device and method, improves Water-oil separating rate;Using the different and its incompatible characteristic of grease density, in high slot substrate inner cavity since density is different for the first time Separation, low-energy-consumption receives oil in low slot, and without the additional configuration devices such as oil well pump and suction pump, input cost is low, energy saving Environmental protection.
2, it using floating receiving port, can be moved up and down by the flexure spring being wrapped in spacing column, to adapt to liquid level change Change;Floating overflow greasy dirt collection port, with energy synchronizing moving when changing above and below liquid level, is not in move up and down card in sedimentation basin Dead problem;Collection port does not rotate on liquid level with flow movement, and receipts oil-piping layout twist ties is caused to result in blockage.
3, secondary separation automatically controls electric draining valve using infrared sensing device and starts, and saves a large amount of manpower object Power, it is economical and practical.
4, the collection system can be used for underground greasy dirt collection and separation, operate steadily reliable, easy to use, structure letter It is single, it is easy to final-period management and maintenance;The excessive of greasy dirt is avoided simultaneously, can be that enterprise brings certain benefit.
