Description

The drive roll device that is used for the continuous solid-liquid separating machine of curved surface slip pressurization

Technical field

The utility model relates to a kind of drive roll device, especially relate to a kind of drive roll device that is used for the continuous solid-liquid separating machine of curved surface slip pressurization, belong to the continuous solid-liquid separating machine of curved surface slip pressurization, the microparticle that the continuous solid-liquid separating machine of this curved surface slip pressurization mainly is suitable for sewage treatment plant, paper mill, food processing factory, chemical plant and plant etc. contains the liquid material dewatering.

Background technology

Water treatment plant, paper mill, food processing factory, chemical plant and plant etc. all will produce a large amount of materials that needs processed.These materials are through dehydration, after being concentrated again landfill can save a large amount of soils, reduce sewage permeation; Simultaneously, many organic materials in these materials are when being concentrated to certain solid content, just can be directly used in comprehensive utilization, thereby save the oven dry energy, pressed dry 50% when above such as the solid content of paper-making deinking mud, just not needing can realize the burning of postcombustion, its incineration residue can be used as the cement raw material of high-quality.

As open day was on 03 21st, 2007, publication number is CN2880216, the patent No. is to disclose " a kind of high-efficient strong filter press " in 200620100437.3 the Chinese patent, this high-efficient strong filter press is a kind of board-like filter press that combines with belt filter press, it is that multilayer press filtration plate is stacked, material is passed through the clamping of two circulation guipures around the S-shaped trend of press filtration plate, by hydraulic system pressurization squeezing.This technology has solved the problem that traditional chamber-type press filter filter cloth cleans, the filter cloth replacing is time-consuming, and still, still there are the following problems for it.

1, owing to adopt hydraulic pressure back and forth to pressurize, so can only take intermittently operated, tape transport, pressing, discharging must be carried out step by step, so inefficiency.In addition,, make cloth be difficult to evenly, and then cause squeezing effect and differ also because be the reason of intermittently operated.

2, owing to its squeezing pressure provides by hydraulic cylinder fully, and the stroke of hydraulic cylinder is limited, so the filter plate quantity of every equipment is difficult to compare with traditional chamber filter press, can accomplish 100 blocks more than the plate such as common plate type pressure filter, and this utility model is generally about 10 blocks of plates, to improve output, to reduce equipment manufacturing cost all very unfavorable.

Aspect the high dehydration of continuous operation filtering equipment pressure, as open day was on December 20th, 2006, publication number is CN1879932, the patent No. is to disclose " a kind of belt filter press " in 200610050778.9 the Chinese patent, thereby this belt filter press provides high-tension to improve the technology of dehydration pressure by steel strip, its dehydration pressure is being obtained substantial progress up to 3.0Mpa aspect the heavy as before sludge filter cake solid content of the bigger material ratio of raising frictional force; But for the material of stick-slip character, such as municipal activated sludge, so high squeezing pressure will inevitably cause the sideslip and the difficult feed of material, is difficult to carry out effective squeezing.

At present some solid-liquid separating equipment adopts drive unit to drive live-roller, and then drives filter bag by live-roller and move, and makes mud on the filter bag enter pressed zone and squeezes.Such solid-liquid separating equipment in use, improve the solid content of mud by the pressure that increases pressed zone, thereby increased the resistance of pressed zone to filter bag, need overcome the resistance of pressed zone to filter bag this moment by the driving force that increases drive unit, if the coefficient of friction between live-roller and the filter bag is constant, after the driving force of drive unit is brought up to certain value, the phenomenon that can occur skidding between live-roller and the filter bag.Also do not have at present a kind of reasonable in design, functional, can move continuously, squeeze and effective be used for the curved surface drive roll device of the continuous solid-liquid separating machine of pressurization that slides, thereby reduced the overall performance of solid-liquid separating machine.

The utility model content

The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and functional, can move continuously, drainage effect is good, the drive roll device that is used for the continuous solid-liquid separating machine of curved surface slip pressurization that the squeezing effect is good.

The technical scheme in the invention for solving the above technical problem is: this drive roll device that is used for the continuous solid-liquid separating machine of curved surface slip pressurization comprises drive roll, described drive roll is made up of roll shaft and roll body, this roll shaft is fixed on the roll body, described roll body is a cylindrical structural, its characteristics are: also comprise the water guide cover, described drive roll suit is fixed in the water guide cover, and the outside wall surface of described water guide cover is provided with a few rhones.

A few rhones that water guide described in the utility model puts all distribute along the radial direction of drive roll.

The groove width of rhone described in the utility model is between 0.2-6mm, and the groove depth of this rhone is between 2-8mm, and the centre distance between adjacent two rhones is between 2-20mm.

Water guide cover described in the utility model is cylinder-like structure.

Water guide cover described in the utility model is the rubber material.

The utility model compared with prior art, have the following advantages and effect: the water guide cover is coated on the drive roll, just can drive the water guide cover by the rotation drive roll rotates, the outside wall surface of water guide cover is provided with a few rhones, the effect of rhone is to be used for getting rid of the moisture that material is deviate under the pressure state, has improved the squeezing effect.In addition, rhone can also be used to increase coefficient of friction, is convenient to drive, and can more effectively improve the squeezing effect.
