Technical Field

The invention relates to a screw press, in particular to a vertically-mounted screw press with a drainage function.

Background

The existing screw press on the market generally comprises a feed hopper, a pressing screw, a spiral pipe, a slag discharge pipe and a driving device. The slag enters the spiral pipe from the feed hopper and is extruded and dehydrated under the action of the pressing spiral. The water squeezed out from the material is collected to the water receiving basin through the filter screen and is discharged by the drain pipe, and the material is compressed and then is discharged through the slag discharge pipe, so that the weight and the volume of sundries such as grid slag and the like can be greatly reduced. The screw press consists of a drainage area, a feeding area, a screw conveying area and a discharging area. And (3) feeding the grid slag into a material feeding area, compacting the grid slag in the compacting area through a screw press, discharging the grid slag, and allowing waste liquid to flow into a water collecting pipe from the grid bars.

At present, silt and solid impurities in a rainwater well are deposited all year round after rainwater and sewage are shunted, a rainwater pipe network is easily blocked, and the quality of water is easily influenced due to excessive deposited impurities. A device is needed for screening, squeezing and transporting sludge or solid impurities. The device can be adjusted according to the condition, and according to local conditions, the vertical installation can utilize current catch basin or bilge well, need not too much civil engineering transformation, and current screw press can't adapt to the requirement of above-mentioned operation, and especially the dehydration effect is difficult to reach the requirement of use, consequently needs the improvement.

Disclosure of Invention

In order to solve the defects in the prior art, the invention provides the vertically-installed screw press with the drainage function, which can realize the screening, squeezing and outward transportation treatment of solid impurities in a sewage well, and has good filtering and dewatering effects by arranging a secondary filtering structure.

In order to realize the technical scheme, the invention provides a vertically-installed screw press with a drainage function, which comprises a main body which is vertically and downwards arranged, wherein a shaftless screw rod is installed in the main body, a driving motor is installed at the top of the main body and is connected with the shaftless screw rod, the bottom of the main body adopts a non-sealed open structure, a cylindrical primary filter screen is fixed at the bottom of the main body, one side of the cylindrical primary filter screen is provided with a water inlet distribution cavity, a sewage inlet pipe is arranged on the water inlet distribution cavity, the top of the shaftless screw rod is provided with a secondary dewatering filter screen, the main body at one side of the secondary dewatering filter screen is provided with a drainage hose, the bottom of the drainage hose is communicated with the water inlet distribution cavity arranged at the bottom of the main body, the top of the secondary dewatering filter screen is provided with a dreg pressing screw, one side of the dreg pressing screw is provided with a dreg outlet.

In above-mentioned technical scheme, among the actual operation process, sewage gets into from the sewage inlet tube to distribute the chamber through intaking and get into preliminary filter residue screen cloth, sewage passes preliminary filter residue screen cloth, and solid impurity is intercepted and falls into the bottom to preliminary filter residue screen cloth in the water, and the filter residue that the interception got off is driven by shaftless hob, upwards transmits, and the shaftless hob is driven by driving motor and rotates. In the upward spiral transportation process, water in the filter residue leaks downwards or slides downwards along the pipe wall of the main body due to the influence of gravity, and the filter residue is continuously dewatered. When reacing device upper portion secondary dregs dewatering area department, the filter residue is further dehydrated through secondary dehydration filter screen, and the weight of filter residue constantly superposes, extrudees, and the moisture that extrudes passes through secondary dehydration filter screen, finally assembles together, gets back to into water distribution chamber again along the drainage hose, and the filter residue forms the mud cake of low moisture content under the dregs squeezes continuous squeezing dehydration of spiral at last to discharge through the slag notch.

Preferably, preliminary filter residue screen cloth is cylindrical metal filter screen, cylindrical metal filter screen fixes on the outer wall of main part fuselage bottom, sets up main part fuselage bottom to do not have the sealed open structure and can discharge from the bottom fast for rivers after squeezing, and the filter residue after the filtration falls into the bottom formation gathering to preliminary filter residue screen cloth simultaneously to upwards carry through shaftless hob.

Preferably, the diameter of the mesh of the primary filter residue screen is 5-10 mm.

Preferably, the secondary dehydration filter screen is cylindrical metal filter screen, cylindrical metal filter screen is fixed on the inner wall of main part fuselage, the mesh diameter size of secondary dehydration filter screen is 1 ~ 5 mm.

Preferably, a plurality of fuselage support frames are arranged on the outer side of the main body fuselage, so that the main body fuselage can be conveniently and externally mounted and fixed.

Preferably, the bottom of the preliminary filter residue screen is provided with a supporting leg, so that the preliminary filter residue screen is supported and fixed conveniently.

The invention has the following beneficial effects: this vertical installation's screw press of taking drainage function does not have sealed open structure through adopting the bottom to cup joint the preliminary filter residue screen cloth of cylindrical in main part fuselage bottom, the distribution chamber that intakes sets up on preliminary filter residue screen cloth, this kind of structural design, rivers after being convenient for squeeze can be discharged from the bottom fast, and the filter residue after the filtration falls into the bottom formation gathering to preliminary filter residue screen cloth simultaneously, and upwards carries through shaftless hob. This device has formed four squeezing zones such as cylindrical screen cloth primary filtration district, heliciform transportation squeezing zone, secondary dregs dewatering zone and dregs squeezing zone in the course of the work of reality, and it is effectual to filter and dewater, and solid impurity is at the in-process of upwards carrying, and volume and weight have all reduced 35% -40%, make things convenient for the transportation and the processing of follow-up impurity. And the existing building structure can be utilized, the civil engineering change is less, and the maintenance cost and the early investment cost are lower.
