Description

Treatment device for sewage
Technical Field
The invention belongs to the field of sewage treatment, and particularly relates to a sewage treatment device.
Background
Along with the increase of urban population in China, domestic water consumption in cities is more and more, urban domestic sewage mainly comprises kitchen washing, toilet flushing, bathing, laundry water and the like, the sewage contains a lot of solid substances, organic nitrogen and ammonia nitrogen, a large amount of solid substances, organic nitrogen and ammonia nitrogen contained in the sewage become main pollution sources of urban water in China, and the urban sewage is discharged into rivers and lakes without being purified to pollute natural water bodies and surrounding environment; a large amount of sewage is directly discharged, so that not only is the ecology damaged, but also the industrial and agricultural production and the health and the safety of human beings are seriously harmed.
When handling domestic sewage, the preliminary edulcoration is filtered to the solid class impurity in the sewage earlier generally, then organic nitrogen and ammonia nitrogen to in the sewage decompose the processing, sewage after the processing can discharge in the middle of the nature, but when filtering the solid impurity in the sewage, adopt filtering material to carry out mechanical filtration to the impurity in the sewage more, filterable in-process, filtration pore in the filtering material can be by quick shutoff, lead to filtering material to need carry out the replacement of high frequency, the in-process of replacement need be to be suspended the filtration of sewage, the filter speed that leads to sewage descends, need consume a large amount of filtering material and filter sewage when filtering simultaneously, lead to the filtration cost height of sewage, and then the filtration efficiency who leads to sewage is with low costs high.

Principle of the basic scheme: during the operation, when the filtering layer can normally filter sewage, with the leading-in first inlet tube of sewage, the velocity of flow of sewage in the first inlet tube is lower, and first inlet tube adds sewage to the filtering layer that is located the mounting hole of filter vat top this moment, and the filtering layer offsets with the upper surface of locating piece this moment, and the extension spring between the locating piece is in compression state, and telescopic link and supporting shoe support the filtering layer, and the water in the filtering layer upper surface enters into the filter vat through the filtering layer.
When a certain filtering layer reaches the filtering limit, the rotating shaft is rotated, the rotating shaft drives the mounting ring to rotate and simultaneously drives the filtering units to synchronously rotate, when the filtering layer moves to the electromagnet, the rotating shaft stops rotating, the electromagnet is started, the electromagnet attracts the positioning blocks, further, the positioning holes are driven to move along the direction of the sliding rod away from the filtering layer, further, the distance between the positioning blocks is enlarged, the tension spring is stretched, the upper end of the filtering layer at the moment is short of support, the first water inlet pipe is moved, the flow velocity of sewage in the first water inlet pipe is improved, the sewage rapidly impacts the filtering layer, the telescopic rod pulls the filtering layer to move downwards under the action of impact force, meanwhile, the flexible filtering layer deforms at the lower edge under the action of the impact force and turns outwards, the sewage pushes a large amount of impurities on the surface of the filtering layer into a sewage barrel; after cleaning, the first water inlet pipe is closed, the flexible filter layer is turned back to the original position, the telescopic rod pushes the filter layer to move upwards, then the electromagnet is closed, the tension spring is shortened, the positioning block is moved back to the original position, and the positioning block clamps the filter layer again.
Then the rotating shaft is rotated, the filter layer is moved to the upper part of the filter barrel again, sewage is continuously added into the filter layer, and the filter layer continuously filters the sewage.
The advantages of the basic scheme are: 1. the filtering layer, the supporting block, the telescopic rod and the supporting frame in the filtering unit are matched with each other, so that the filtering layer can clean impurities on the surface under the impact force of sewage, and further, the filtering layer can be used for multiple times; in the process, the telescopic rod can drive the filtering layer to move downwards and descend, so that impurities on the filtering layer can be fully collected into the sewage bucket; the soft filtering layer can be turned over under the action of impact force, so that impurities on the filtering layer can be conveniently and fully washed; 2. the positioning block can be matched with the sliding rod and the electromagnet, so that the filter layer is conveniently loosened in the cleaning process of the filter layer, and the cleaning of the filter layer is realized; meanwhile, after the filtering layer is cleaned, the sliding block can clamp the filtering layer again under the action of the tension spring; the sliding rod can guide the sliding of the positioning block, so that the positioning block can slide stably, and the positioning block can return stably; 3. the collecting barrel is divided into a sewage barrel and a filtering barrel, the filtering barrel can collect the filtered water, and the sewage barrel can collect the cleaning water of the filtering layer, so that the water can be partitioned conveniently; the lateral wall of slop pail and filter vat all is equipped with the through-hole, and when the pivot drove the collar and rotates, support frame, supporting shoe and telescopic link can rotate in step, avoid taking place to interfere with the lateral wall of slop pail and filter vat.
Finally, the rotating mechanism is arranged in the device, the filtering unit is arranged in the rotating mechanism, the filtering layer in the filtering unit can fully filter solid impurities in the sewage, and meanwhile, the filtering layer in the mounting hole can be quickly cleaned by rotating the mounting ring, so that the filtering layer can be used for multiple times; meanwhile, the collecting barrel is divided into a sewage barrel and a filtering barrel, so that filtered water and sewage for cleaning the filtering layer can be collected respectively.
Further, still include the second inlet tube, the second inlet tube fixed mounting is in the top of slop pail. Let in the washing in to the second inlet tube, be exclusively used in the washing of filtering layer, the degree of cleaning that can effectual improvement filtering layer need not to remove first inlet tube this moment and can wash the filtering layer, can improve the cleaning efficiency of filtering layer.
The power mechanism comprises a fixing frame, a plurality of connecting rods and a motor driving the rotating shaft to rotate, the fixing frame is fixedly installed above the cover plate, the motor is fixedly installed on the fixing frame, one end of each connecting rod is fixedly connected with the side face of the corresponding rotating shaft, and the other end of each connecting rod is fixedly connected with the upper surface of the corresponding mounting ring.
