Description

Rural domestic sewage treatment equipment

Technical Field

The utility model relates to a sewage treatment technical field, concretely relates to rural domestic sewage treatment equipment.

Background

The rural domestic sewage treatment is to remove and degrade harmful substances and environmental pollution components in the domestic sewage for harmless treatment. At present, the treatment technologies for treating rural domestic sewage applied at home and abroad are more, the names are also various, but the treatment technologies can be generally classified into two types from the technical principle: the first is a natural treatment system, which utilizes the principles of soil filtration, plant absorption and microbial decomposition, also known as an ecological treatment system; the second type is a biological treatment system, which is to deliver oxygen to sewage by a fan and other devices, culture biological strains and microorganisms, decompose most organic matters in the sewage into pollution-free substances such as carbon dioxide, water and the like by the strains and the microorganisms, synthesize a small part of the substances into cell substances, promote the growth of the microorganisms, decompose impurities in the sewage, discharge the impurities in the form of residual sludge and purify the sewage.

However, the rural domestic sewage contains various impurities, such as plastic bags, food peels, various sludge and the like, the volume of the impurities is large, and the impurities fall into the sewage tank and are difficult to be rapidly decomposed, so that the rural domestic sewage is filtered firstly. The prior art generally adopts grid or filter screen to intercept impurity, for example CN110743220A mentions a rural domestic sewage ecological treatment equipment, its structure includes riser, support frame, impurity processing mechanism, water purification room, wash port, go up support frame, clamp plate, through setting up impurity filtering processing mechanism, impurity, paper products will be direct remain above impurity filter screen layer, can't enter into on the filter screen frame, when handling it, taking out impurity filter screen layer and clearing up, the effectual impurity that avoids enters into water purification processor inside. However, it is difficult to take out the filter screen layer and treat the impurities, the filter screen layer needs to be hoisted, and the impurities can be toppled over if the balance is not kept during hoisting.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to prior art's not enough, design an improvement equipment convenient to collect and handle impurity.

One of the purposes of the utility model is to provide rural domestic sewage treatment equipment, which comprises a filtering tank, wherein a filtering net layer is arranged in the filtering tank, and one end of the filtering tank is provided with a water outlet; the shape of the filter screen layer is matched with the inner wall of the filter tank, the filter screen layer inclines downwards towards one side of the water outlet, the high end of the filter screen layer is positioned at the top of the filter tank and is hinged with the filter tank, the edge of one side of the low end of the filter screen layer is bent upwards, a lifting device for driving the filter screen layer to lift is arranged beside the filter tank, the lifting device comprises a rack, a winch and a lifting rope, the winch is installed on the rack and is driven by a motor to realize winding, one end of the lifting rope is wound on the winch, and the other end of the lifting rope is fixed on the edge of the filter screen layer.

The utility model discloses a theory of operation and beneficial effect: the utility model discloses during the conventional use, put into the filtering ponds with filtering the stratum reticulare, and this filtering the stratum reticulare inclines to place, pour domestic sewage into the filtering ponds from the top, domestic sewage behind filtering the stratum reticulare, can be to paper goods in the sewage, the plastic bag, food peel miscellaneous interception, and on being held back filtering the stratum reticulare, and the sewage that filters impurity flows through filtering ponds bottom and finally discharges from the outlet, and the impurity that is filtered the stratum reticulare interception is then piled up in its upper portion gradually, after a period, when needs clear away impurity in filtering the stratum reticulare, the starter motor, make the hoist engine begin to convolute lifting rope, lifting rope pulling filtering net layer upwards promotes, filtering the stratum reticulare is rotatory around the pin joint of high end, the high perk of filtering the stratum reticulare at last, the angle of slope is too high or borrows the instrument, all can be very convenient will filter the impurity on the stratum reticulare and scrape off, reach the purpose of quick clearance.

The utility model discloses compare in prior art, to filter the slope of stratum reticulare and set up and connect hoisting accessory, filter the border of stratum reticulare low side one side and upwards buckle, form the load-bearing part of the spill that loads impurity, can fine loading impurity, and the equilibrium of hoist and mount can be guaranteed to above structure, avoid the slope, can be rapid after hoist and mount will filter the impurity on the stratum reticulare and unload.

Furthermore, the inclination angle of the filter screen layer in the filter tank is 10-20 degrees. The angle of slope is less, and is along with the direction slope of rivers, on the one hand with the edge cooperation of the filter screen layer of upwards buckling, the impurity that bears that can be fine, on the other hand also can avoid impurity to empty when upwards lifting by crane.

Furthermore, the mesh aperture of the filter screen layer is 20-50 mm. Impurities larger than 20mm can be trapped.

Further, the motor of the winch is electrically connected with a controller. Through the control of controller, when using at ordinary times, in order to ensure filterable effect, when not needing hoist and mount clearance, the starter motor, release from top to bottom or the several lifting ropes of rolling for filter screen layer is around articulated department upset several times, under the effect of rivers, piles up impurity together and can be dispersed, ensures the filter effect, treats when accumulational impurity is sufficient, the clearance of concentrating again.

Further, the shape of the filtering tank is a semi-ellipse, and the shape of the filtering net layer is a semi-ellipse jointed with the filtering tank. The shape design of the filter tank is combined with the installation and the lifting of the filter screen layer, so that the stability can be well maintained.

The frame is further arranged at the edge of the filter tank between the low end and the high end of the filter screen layer, two opposite slide rails are arranged on the side edge of the frame and on one side facing the water outlet, the slide rails are obliquely arranged, a slide rod is arranged between the two slide rails, and the lifting rope is sleeved on the slide rod in a circle. When the filter screen layer is lifted upwards and arrives at the slide rod, the slide rod can slide upwards on the slide rail, the filter screen layer can be lifted higher, and the lifting rope is protected, and meanwhile, the lifting stability of the filter screen is further improved.
