Detailed introduction

The stacked screw filter equipment first appeared in the 19th century European industrial revolution. The earliest industrial filter equipment came out including filter presses, leaf filters, and screw filters.

Spiral filter is also called spiral squeeze dewatering machine. With the development of spiral filter technology, in order to avoid clogging problems, such as grid filter structure, dynamic fixed ring filter structure, etc. : 固定环片和活动环片。 Among them, the dynamic fixed ring structure screen is covered with multiple rings on the spiral shaft, and the rings are divided into two types : fixed rings and movable rings. The fixed ring and the movable ring are spaced apart from each other and have a certain filtering gap. Through the friction between the movable ring and the fixed ring, the friction force that promotes the extrusion of the material is greater than the hindrance, thereby improving the filtering and separating effect of the material and avoiding Blocking of high viscosity materials.

Due to the characteristics of easy separation and non-blocking of the stacked screw dewatering machine, it has been widely used in many fields such as municipal sewage treatment and industrial wastewater treatment, petrochemical industry, medicine, textile, metallurgy, food and beverage, and mining.

 

working principle

: 当螺旋推动轴转动时,设在推动轴外围的多重固活叠片相对移动,在重力作用下,水从相对移动的叠片间隙中滤出,实现快速浓缩。 1. Concentration : When the screw driving shaft rotates, the multiple solid and fixed laminations located on the periphery of the driving shaft move relative to each other. Under the action of gravity, water is filtered out from the relative lamination gaps to achieve rapid concentration.

: 经过浓缩的污泥随着螺旋轴的转动不断往前移动 ; 沿泥饼出口方向,螺旋轴的螺距逐渐变小,环与环之间的间隙也逐渐变小,螺旋腔的体积不断收缩 ; 在出口处背压板的作用下,内压逐渐增强,在螺旋推动轴依次连续运转推动下,污泥中的水分受挤压排出,滤饼含固量不断升高,最终实现污泥的连续脱水。 2. Dehydration : The concentrated sludge moves forward with the rotation of the screw shaft ; along the direction of the mud cake exit, the pitch of the screw shaft gradually becomes smaller, the gap between the rings becomes smaller, and the volume of the spiral cavity becomes smaller. Constant shrinkage ; under the action of the back pressure plate at the outlet, the internal pressure gradually increases. Under the continuous driving of the screw drive shaft, the water in the sludge is squeezed out, and the solid content of the filter cake is continuously increased, eventually achieving the sludge. Continuous dehydration.

: 螺旋轴的旋转,推动游动环不断转动,设备依靠固定环和游动环之间的移动实现连续的自清洗过程,从而巧妙地避免了传统脱水机普遍存在的堵塞问题。 3. Self-cleaning : The rotation of the screw shaft promotes the continuous rotation of the swimming ring. The device relies on the movement between the fixed ring and the swimming ring to achieve a continuous self-cleaning process, thereby cleverly avoiding the problem of blockages commonly existing in traditional dehydrators.

 

Construction principle

, 螺旋轴贯穿其中形成的过滤装置 . 前段为浓缩部 , 后段为脱水部 . The snail body of the snail dewatering machine is a filtering device formed by the fixed ring and the floating ring stacked on each other , and the spiral shaft penetrates through it . The front section is the concentration section and the rear section is the dewatering section .

The filter gap formed between the fixed ring and the floating ring and the pitch of the screw shaft gradually become smaller from the concentrated part to the dewatered part.

The rotation of the screw shaft, while pushing the sludge from the thickening section to the dewatering section, also continuously drives the swimming ring to clean the filter gap to prevent clogging.

 

Dehydration principle

, 叠螺机被运输到脱水部 , 在前进的过程中随着滤缝及螺距的逐渐变小 , 以及背压板的阻挡作用下 , 产生极大的内压 , 容积不断缩小 , 达到充分脱水的目的。 After the sludge is concentrated by gravity in the concentrating section , the stacking screw machine is transported to the dewatering section . During the process of advancement, as the filter seam and pitch gradually become smaller , and the blocking effect of the back pressure plate generates a great internal pressure , The volume is continuously reduced to achieve the purpose of full dehydration.

 

Product advantages

Widely applicable

1.Suitable for municipal sewage, food, beverage, chemical, leather, welding materials, papermaking, printing and dyeing, pharmaceutical and other industries.

2. Suitable for dehydration of high and low concentration sludge. (2000mg/L~) 污泥脱水时,无需建设浓缩池、贮存池,降低建设成本,减少磷的释放和厌氧臭气的产生。 When low-concentration (2000mg / L ~) sludge is dewatered, there is no need to build a concentration tank or storage tank, which reduces the construction cost, reduces the release of phosphorus and the generation of anaerobic odor.

Small design

1. Compact design. The dewatering machine contains an electric control cabinet, a measuring tank, a flocculation mixing tank and a dewatering machine.

; 重量小,便于搬运。 2. Small space for easy maintenance and replacement ; small weight for easy handling.

Not easy to block

1. With self-cleaning function. There is no need to clean the filter to prevent clogging, reduce the amount of flushing water and reduce the burden on the internal circulation.

2. Good at dehydration of oily sludge.

Low speed operation

2~3 / 分,耗电极低。 1. The rotation speed of the screw shaft is about 2 ~ 3 rpm , and the electrode consumption is low.

2. Less failure, less noise and vibration, safe operation.

easy to use

24 小时连续无人运行。 1. Through the electric control cabinet, it can be linked with the medicine infusion machine, mud inlet pump, dosing pump, etc., to achieve continuous unmanned operation for 24 hours.

2. The daily maintenance time is short and the maintenance operation is simple.

Durable

1. The body is almost entirely made of stainless steel, which can extend the service life to the maximum.

2. The only replacement parts are the screw shaft and the travel ring, and the service life is long.

Reduced design, construction, and operating costs

Different product specifications and complete series. According to different processing scales, the most suitable model can be selected to avoid overuse of small materials.

Compact body design, integrated concentration and dehydration, with auxiliary devices such as electric control cabinet and sludge flocculation mixing tank, which has strong compatibility with supporting equipment and is easy to design.

Small design, easy to adapt to local conditions, can reduce the space and construction cost of the dehydrator itself.

● It has the function of sludge concentration, so no concentration and storage unit is needed, reducing the overall land occupation space and construction cost of sewage treatment facilities.

● The main body of the dehydrator has a self-cleaning function, so there is no need to wash a lot of water to prevent sludge clogging.

Using low-speed screw extrusion technology, low power consumption.

24 小时全自动连续无人运行,降低工人费。 Electrical control cabinet is equipped with automatic control device, from conveying sludge, injecting liquid medicine, concentrating and dehydrating to discharging mud cake, realizing 24- hour automatic continuous unmanned operation, reducing labor costs.
