What are the advantages and technical requirements of the screw stacking dehydrator?

The advantages of the machine include compact design, small floor area, low operation cost, water and electricity saving, simple operation and long service life; In addition, the technical requirements, such as all moving parts should run smoothly, without vibration and noise, dehydrator should be equipped with special T-type wrench and plug gauge for back pressure plate, etc., are described in detail below.

1、 The advantages of the stacked screw dehydrator

1. Compact design, small footprint

It is suitable for all kinds of installation environment. It can connect the circuit according to the drawing. It is simple and easy to use.

2. Low operating cost, water and electricity saving

It can realize self-cleaning and save a lot of cleaning water. The power consumption is very small, and the power consumption is only 5% of the centrifuge with the same processing capacity

3. Simple operation and long service life

Good stability, few routine maintenance items and simple maintenance operation.

4. Wide range of applications, strong applicability

Can be widely used in municipal sewage, chemical industry, petroleum, tap water, printing and dyeing, paper industry sewage treatment.

2、 Technical requirements of screw stacking dehydrator

1. The body is divided into concentration section and dehydration section. The materials of concentration section and dehydration section are SS304

2. The equipment shall be able to realize full-automatic operation with automatic sprinkling and flushing device. The flushing device is composed of a spray pipe and a spray nozzle, and the spray range should cover the whole dewatering body, and each nozzle can be replaced. The flushing device should have good airtightness.

3. All moving parts should run smoothly without vibration and noise. The rotation speed of the screw shaft is adjustable, and the speed range is 2-3 rpm.

4. The spiral shaft is an inverted cone structure in the dehydration section, which should have the function of gas pushing and anti blocking. The shaft core is equipped with rotary joints and multiple unidirectional air outlets, which can blow air in from the shaft core and blow air out in time through the pores, which can not only ensure that the sludge does not stick to the shaft wall, prevent blockage, but also further reduce the moisture content.

5. The floating ring is a special-shaped anti blocking ring, which should be flat and smooth. The outer edge of the floating ring should be equipped with anti blocking handle, which can not only effectively prevent the sludge from blocking in the screw stacking cavity, but also enhance the shear force and propulsion force of the sludge.

6. The main body should be equipped with detachable ring piece, which is convenient for quick repair and observation of the wear of spiral shaft piece in case of sludge blockage.

7. It is equipped with filtrate diversion tank to realize filtrate diversion of concentration section and dehydration section. The filtrate from the concentration section is collected into the filtrate collection tank, and the filtrate from the dehydration section automatically returns to the flocculation mixing tank after it is full. The solid recovery rate of the dehydrator can be improved by reprocessing without or with little addition.

8. The dehydrator shall be equipped with special T-type wrench and plug gauge for back pressure plate to accurately adjust the clearance of back pressure plate. The sludge outlet shall be equipped with sludge scraping device to ensure the timely discharge of sludge that may harden at the outlet.

9. The driving device shall have overload and overheat protection function. The protection grade of the motor is IP55, F-class insulation, all of which are waterproof. The design of reducer gear shall be in accordance with ISO or equivalent standards, the service factor shall not be less than 2.0, the gear shall be carburized with low alloy steel, and the surface hardness shall not be less than hrc58. All joint surfaces, input and output shaft seals shall be free of leakage.

The above is all about "what are the advantages and technical requirements of the stacked screw dehydrator?" I hope it can help you.
