Winter maintenance of sludge decanter centrifuge

The cold weather in winter is a period when the sludge dewatering  Decanter centrifuge is seriously damaged. The sludge dewatering decanter centrifuge must be inspected and maintained on a regular basis to do the pre-prevention work. Below we will tell you how to maintain the sludge dewatering decanter centrifuge in winter.

2023.03.23 inorganic salt crystal dewatering centrifge

The manufacturer of sludge dewaterin Decanter centrifuge should start from the basic work of sludge dewatering decanter centrifuge management, establish lubrication maintenance and daily maintenance of the main components, and require the operator to pay attention to the water supply of each part of the sludge dewatering decanter centrifuge to prevent freezing before shutting down. Carry out maintenance on all parts, and pay special attention to the filter. The first is to check the flushing water system of the belt-type sludge dewatering decanter centrifuge, the second is to check the bearing lubricating oil, the third, the filter is to prevent the ice from damaging the filter before starting, the fourth is to check the appearance of the solid parts, and to lubricate the contact parts, the fifth is Check whether the air compressor is clean, so that the air source is unobstructed. Sixth, check the emergency shutdown to increase safety, etc., and make lubrication maintenance records.

GN dewatering  Decanter centrifuge  is T series decanter centrifuge with beach angle of 8.5 degrees. GN T series decanter centrifuge is usually used dewatering and thickening purpose. It is widely used for maximum dewatering requirements of municipal and industrial wastewater sludge. The dewatering decanter centrifuge is designed for easy separation material include large particle size, high density difference of solid and liquid, low viscosity, high concentration, high treatment capacity and higher dryness than clarity. The materials like sludge or wastewater containing fine particles usually need to be added with flocculants to gather the fine particles condensed into large ones, and then dewatered with T series decanter centrifuge.

Use and value of manure processed by decanter centrifuge

The first use of manure for electricity generation is relatively mature technology. Use cow dung to generate electricity and make substitutes for biogas and coal. For example, in dairy farms, the annual electricity generated by the fermentation of dried cow manure processed by a cow manure Decanter centrifuge can save 1.2 million yuan in electricity costs. In addition, cow dung sticks and cow dung honeycomb coal can also be developed in a certain place. Cow dung sticks made of cow dung are used as fuel, and the combustion value is high. Cow dung honeycomb coal is compressed with cow dung and coal at a ratio of 4:6, which solves the problem of honeycomb coal. Pollution of the atmosphere.

Feces can also grow Agaricus bisporus and straw mushrooms. The cow dung produced by the milk buffalo is used for biogas power generation. The produced biogas slurry can be made into liquid fertilizer, and the fertilizer is sold for more than 3,000 yuan a ton. The milk produced by milk buffalo is about 4 yuan, but the fertilizer can sell for 100 yuan. This shows that the use of cow dung can not only increase the economic income of cattle farmers, but also bring many economic and social benefits. In order to solve the problem of farming wastewater pollution and build an environment-friendly farming base, the company’s leaders attach great importance to pollution control work, and entrusted our unit to design a plan for the fecal sewage solid-liquid separation treatment project.

The dried cow dung dehydrated by the cow manure Decanter centrifuge can also be used as feed for many animals. The cow manure contains minerals and various nutrients, including organic matter, total nitrogen, crude protein and other nutrients. This is Cow dung is a prerequisite for feed. For example, the cow dung of a cow used to raise earthworms can finally obtain an economic value of about 2400 yuan

After the manure is processed by the decanter centrifuge, according to the similar project investigation and the information provided by the owner, the sewage mainly comes from cow urine and ground washing wastewater, and contains manure and urine.

According to the requirements of the owner, it is necessary to treat about 300 tons of manure sewage produced by 4000 cows every day, and the moisture content of the dried cow manure after treatment is about 60%-70%. The excrement processed by the decanter centrifuge can greatly increase the income of the enterprise, and truly turn waste into treasure.
