Description

Spiral sludge dewatering machine

Technical field

The utility model relates to a kind of spiral sludge dewatering machine for drilling well field.

Background technology

Folded spiral shell formula sludge dewatering equipment can be widely used in the water treatment system that municipal wastewater is processed the industrial trades such as engineering and petrochemical industry, light industry, chemical fibre, papermaking, pharmacy, leather.

Filter plant appears at 19th-century Europe Industrial Revolution period the earliest, and the industrial filter equipment coming out the earliest has pressure filter, leaf filter and spiral filter etc.

When early stage, spiral filter is found such a case when filtering the waste materials such as fish, shrimp, filters while starting, and pan feeding is through extruding, and filtrate flows out from filter screen.But after filtering for some time, filtrate just stops having flowed, and filter cake can not discharged from discharge opening yet, its major cause is that material concentration increases, and because filter structure reason causes filtration efficiency to reduce, has occurred obstruction.

Along with the development of spiral filtering technique, for fear of the problem of occur stopping up, there is a kind of relatively novel filter structure in European countries such as Germany in the seventies last century, its dehydration tube be by several one chips move about ring and fixedly filter disc assemble.On 2010 markets, disclosed a kind of spiral sludge dewatering machine, adopt the spiral sludge dewatering machine of moudle type laminated combination, by disperseing the ring that moves about of assembling to change dismountable modular construction into fixing filter disc, between each lamination module, can replace mutually, and then extend the work-ing life of the ring that moves about.The dehydration tube of this structure prior art is before significantly improved, but also exist following not enough: regulate the restriction in modulated of gap, after need dismantling in the time of need to replacing dewatering period and enriching section, ressemble and regulate gap, complex operation, workload are large.Meanwhile, dewatering operation also makes water extracter easily occur that dehydration rate is not high frequently, and sludge outlet holds susceptible to plugging problem.

Utility model content

For solving this technical problem, the utility model provides a kind of adjustable stacked spiral type sludge dewatering machine, comprises frame support, clay supply device, screw shaft, drive-motor, filter disk assembly and mud extraction device; Filter disk assembly consists of through spaced fixedly filter disc and the movable filter disc of screw shaft periphery vertically some, flexible adjustment piece is fixedly housed between filter disc, flexible adjustment piece is that the elastomeric pad of uniform thickness combines, the thickness of elastomeric pad is 0.5～1mm, and opening scope is between 120 ° to 180 °; Screw shaft is provided with setting device in one end of mud extraction device, setting device comprises: the standing bolt that is arranged on screw shaft end, the outside elastomeric element that connects of standing bolt, the outside adjustable plate that connects of this elastomeric element, adjustable plate is arranged on the mud mouth place of the dewatering cavity of screw shaft formation.

Accompanying drawing explanation

Accompanying drawing 1 is spiral sludge dewatering machine schematic diagram of the present utility model.

Embodiment

Spiral sludge dewatering machine of the present utility model has used screw extruding principle, changes the powerful squeeze producing by screw diameter and pitch, and move about ring and the fixing micro gap between filter disc, and realization is carried out extrusion dehydration to mud; Mud after gravity concentration, is transported to dehydration portion in concentrated portion, in the process of advancing, along with the diminishing gradually of filter seam and pitch, and under the barrier effect of back pressure plate, presses in producing greatly, and volume constantly dwindles, and reaches the object of abundant dehydration.

Spiral sludge dewatering machine of the present utility model comprises frame support, clay supply device, screw shaft, drive-motor, filter disk assembly and mud extraction device, described filter disk assembly consists of some spaced fixedly filter disc and the movable filter disc through screw shaft periphery vertically, flexible adjustment piece is fixedly housed between filter disc, described flexible adjustment piece is uniform thickness, have the elastomeric pad that is less than 180 ° of openings combines, the thickness of described elastomeric pad is 0.5～1mm, and its opening scope is between 120 ° to 180 °; Described screw shaft is provided with setting device in one end of described mud extraction device, and described setting device specifically comprises: the standing bolt that is arranged on described screw shaft end; The outside elastomeric element that connects of described standing bolt, the outside adjustable plate that connects of this elastomeric element, described adjustable plate is arranged on the mud mouth place of the dewatering cavity of described screw shaft formation.

As shown in Figure 1, spiral sludge dewatering machine of the present utility model is provided with a frame support 1, is provided with dehydration body 2 in described frame support 1, described dehydration body 2 is connected with clay supply device 3 and mud extraction device 4, described shell 1 also has water box 5, and wherein, described dehydration body 2 specifically comprises:

Two ends, left and right extend to respectively the screw shaft 21 of described clay supply device 3 and mud extraction device 4; On screw shaft, be connected with drive-motor;

Be sleeved on the filter disk assembly on described screw shaft 21, comprise movable filter disc 22 and be arranged on the fixedly filter disc 23 between adjacent movable filter disc 22;

Described screw shaft 21 is provided with setting device 6 in one end of described mud extraction device 4, and described setting device 6 specifically comprises: the standing bolt 61 that is arranged on described screw shaft 21 ends;

The outside elastomeric element 62 that connects of described standing bolt 61, the outside adjustable plate 63 that connects of this elastomeric element 62, described adjustable plate 63 is arranged on the mud mouth place of the dewatering cavity of described screw shaft 21 formation.During work, the adjustable plate of setting device constantly regulates the pressure of mud mouth, makes mud mouth be operated in one comparatively stably under pressure state, has realized high dehydration rate.

In addition, every adjacent two fixedly the gap between filter disc be slightly larger than the thickness of being located at the filter of moving about therebetween, this gap regulates setting according to processing the contained sludge quality of object by the flexible adjustment piece fixedly filling between filter disc, and the scope that arranges is generally between 1.5～3mm.Flexible adjustment piece is uniform thickness, have the elastomeric pad that is less than 180 ° of openings combines, and the thickness of described elastomeric pad is preferably 0.5～1mm, and its opening scope is between 120 ° to 180 °.According to the size in required adjusting gap, can be combined into the regulating block of different thickness.When this elastomeric pad of dismounting, utilize the elasticity of elastomeric pad pad can be taken off or installs.This flexible adjustment block structure can be realized in the situation that not carrying out integral demounting the fixing gap between filter disc adjusting by elastomeric pad is re-assemblied, enriching section and dewatering period are changed to use, reach simple to operate, time saving and energy saving, reusable object, extended the fixedly working life of filter disc and movable filter disc.
