Abstract
The utility model discloses a screw extrusion sludge dewatering machine. The screw extrusion sludge dewatering machine comprises a barrel-shaped sludge box (1) which is horizontally placed, wherein the right end of the sludge box (1) is provided with a sludge inlet (1a) with an upward opening, the left end of the sludge box (1) is provided with a sludge outlet (1b), the lower part of the sludge box (1) comprises a filter screen (7), the sludge box (1) is internally provided with an extrusion screw (2) with fan blades, the left end of the extrusion screw (2) is connected with a driving device (3), a first terminal (4) is arranged on the extrusion screw (2), and a second terminal (5) is arranged on a filter screen (1b). The screw extrusion sludge dewatering machine can be used for greatly improving the dewatering efficiency by respectively switching positive pole electric charges and negative pole electric charges into the extrusion screw and the filter screens and meanwhile has the advantages of stability in dewatering, relatively low noise, low improvement cost and the like.
Description
Technical field
The utility model relates to field of Environment Protection, particularly relates to a kind of equipment for sludge dewatering.
Background technology
Mud is the solid precipitation material produced by water and sewage treatment process, and sludge dewatering is exactly that primary, the concentrated or digested sludge of fluidised form is removed to moisture, is converted into a kind of method for sludge treatment of semi-solid state or solid-state clod.After dehydration, moisture percentage in sewage sludge can be reduced to 80 55 percent to percent, and the method for dehydration mainly contains nature mummification method, mechanical dehydration method and comminution granulation.In general, adopt mechanical dehydration can obtain the solid content of 20%-30%, formed mud is also referred to as mud cake.Current existing mechanical dehydration method has filters and centrifuging, and wherein the equipment of filtration method use mainly contains the screw extrusion water extracter.It is exactly directly to adopt the screw rod with flabellum to carry out extrusion dehydration to wet mud that the spiral shell used on the market selects extruding-desiccation machine, and dewatering efficiency is lower.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of high efficiency screw extrusion sludge dewatering equipment.
The technical solution of the utility model is as follows: a kind of screw extrusion sludge dewatering equipment, the mud case (1) that comprises the tubular of horizontal positioned, the right-hand member of described mud case (1) has the mud entrance (1a) of opening upwards, the left end of this mud case (1) offers sludge outlet (1b), and the bottom of this mud case (1) is comprised of filter screen (7), in described mud case (1), be provided with the extrusion screw (2) with flabellum, the left end of this extrusion screw (2) is connected with drive unit (3), it is characterized in that: on described extrusion screw (2), be provided with the first terminals (4), on described filter screen (1b), be provided with the second terminals (5).
While using above-mentioned screw extrusion sludge dewatering equipment, the mud that will wet is poured into from the mud entrance, drive unit drives the extrusion screw rotation, access is anodal on the first terminals of extrusion screw simultaneously, on the second terminals of filter screen, access negative pole, owing between extrusion screw and filter screen, being full of wet mud, thereby the conductor that wet mud has served as between extrusion screw and filter screen is connected circuit, because the electroconductibility of water is greater than dewatered sludge, cause water more from filter screen, leaching, improved the filter dehydration performance of this equipment.
Described extrusion screw (2) is connected with drive unit (3) by isolated flange (6), can prevent that the electric charge that pushes band is passed in drive unit.
In order further to improve the effect of extrusion dehydration, described extrusion screw (2) is the thin structure of the thick end of an end, and this extrusion screw (2) is less than the end diameter of this extrusion screw (2) near sludge outlet (1b) near an end diameter of mud entrance (1a).
Beneficial effect: the utility model is by accessing respectively the positive and negative electrode electric charge on extrusion screw and filter screen, greatly improved the efficiency of dehydration, the characteristics such as also having simultaneously that dehydration is stable, noise is lower and improvement cost is low.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model such as comprises at the parts, the mud case (1) that comprises the tubular of horizontal positioned, the right-hand member of described mud case (1) has the mud entrance (1a) of opening upwards, the left end of this mud case (1) offers sludge outlet (1b), and the bottom of this mud case (1) is comprised of filter screen (7), in described mud case (1), be provided with the extrusion screw (2) with flabellum, described extrusion screw (2) is the thin structure of the thick end of an end, this extrusion screw (2) is less than the end diameter of this extrusion screw (2) near sludge outlet (1b) near an end diameter of mud entrance (1a).The left end of this extrusion screw (2) is connected with drive unit (3) by isolated flange (6).On described extrusion screw (2), be provided with the first terminals (4), on described filter screen (1b), be provided with the second terminals (5).
The foregoing is only preferred embodiment of the present utility model; the utility model of not take is restriction; all any modifications of doing, be equal to the quantity etc. of replacing and improving as change dial framework and benchmark post, within all should being included in protection domain of the present utility model within spirit of the present utility model and principle.
