Pig manure solid liquid separator Brief description: Pig manure solid-liquid separator is a mechanical filtration method. It is suitable for separating the tiny suspended matter (pulp fiber) Z in liquid to a large extent, so as to achieve the purpose of solid-liquid two-phase separation. The difference between the solid-liquid separation and other methods is that the gap of the filter medium is very small. With the help of the centrifugal force of the screen rotation, under the lower hydraulic resistance, the solid-liquid separation has a higher flow rate and can intercept the suspended solids. The solid-liquid separator is a new type of solid-liquid separator, which absorbs New Zealand's all machine technology and is developed according to China's national conditions. It is widely used in various occasions where solid-liquid separation is needed, such as the filtration of municipal sewage, papermaking, food, textile, printing and dyeing, chemical sewage, etc., so as to achieve closed circulation and reuse.
working principles
working principle: The feces of pig farms and cattle farms are the main pollution sources. Most of the feces produced by farms are piled up in the open air without any treatment. The feces contain a lot of salt and drug residues and can not be directly fertilized. If the solid-liquid separator is used for extrusion treatment, the moisture and harmful substances in feces can be well removed. After extrusion, the feces can be bagged or piled up for fermentation. After extrusion and fermentation, the feces are pure natural organic fertilizer, which can be used for vegetables, melons and fruits planting or feeding fish. The waste can be turned into treasure completely, greatly reducing the source of pollution. It is necessary to build a fecal storage tank with a volume of about 35 cubic meters. All feces and sewage are put into the tank. The mixing pump is installed above the tank. The mixing pump evenly mixes the feces and sewage in the tank and extracts them to the solid-liquid separator for extrusion and dehydration through the sludge pump to produce dry feces. The working principle of this machine is spiral normal pressure extrusion, which can treat 40 m? Per hour of sewage with high speed and high efficiency, The outer frame is made of stainless steel, durable and practical, which is the key of the farm. Pig manure solid-liquid separator is a mechanical filtration method. It is suitable for separating the tiny suspended matter (pulp fiber) in liquid to a large extent, so as to achieve the purpose of solid-liquid two-phase separation. The difference between the solid-liquid separation and other methods is that the gap of the filter medium is very small. With the help of the centrifugal force of the screen rotation, under the lower hydraulic resistance, the solid-liquid separation has a higher flow rate and can intercept the suspended solids. This equipment is specially developed to solve the problems of the existing microfiltration machine, such as easy to block, easy to damage, heavy maintenance workload, more secondary investment and so on. It is one of the ideal and practical equipment suitable for papermaking wastewater treatment.
Product application
Application and principle of pig manure solid-liquid separator: 1) If the volume of the old biogas digester is too small and the time of sewage flowing into the digester is too short, the sewage concentration is too high, then the livestock manure solid-liquid separator should be used before the sewage goes into the digester. It can effectively reduce the COD and BOD content of the sewage, and reduce the operation load of the biogas digester, so as to reduce the sewage discharge; 2) The solid-liquid separator can transform the feces from fresh sewage into valuable fish feed or organic fertilizer. The separated sewage intermittently enters into the biogas digester, which can make the anaerobic digester have a full digestion time, so that the active bacteria in the digester can reproduce more vigorously and produce more gas. The content of gas is naturally high, and the high purity of gas can be naturally overcome; 3) The sewage treated by the solid-liquid separator enters the biogas digester. The utility model can effectively solve the crusting phenomenon of the biogas digester without the work of cleaning the biogas residue; 4) The construction investment of biogas digester can be reduced by using the solid-liquid separator of livestock manure. For example, if a breeding or slaughterhouse discharges 100 tons of sewage every day, if a matching solid-liquid separator of livestock manure is used for treatment in advance, the construction investment of 300 cubic meters anaerobic digester can be reduced. Because the concentration of sewage mixed into the digester is too high, the anaerobic time also needs to be extended accordingly, so the anaerobic time should be adjusted according to the time of each day If the livestock manure solid-liquid separator is not used for treatment, the farm that discharges 100 tons of sewage. If the livestock manure solid-liquid separator is used, the construction can be reduced by 300-400 cubic meters. Machine requirements: (1) All parts of the whole machine should be well sealed without dripping and leakage. (2) The connection of the top liquid storage frame shall have reliable device. (3) The connection between the vibrator and the screen frame is provided with a reliable anti loosing device. (4) The screen frame and the separator body are equipped with vibration isolation devices. (5) The clearance between the screw blade and the shell of the slag removal screw propeller is not more than 2mm, and there is no friction phenomenon. The sealing device is set at the inner part of the two supporting shafts (for automatic centering) of the screw propeller. (6) The upper part of the transmission chain of the screw propeller is a tight side, and a tight wheel is arranged at the lower part. (7) The external transmission mechanism of the whole machine is provided with a protective cover. (8) The working temperature of rolling bearing is not higher than 70 ºC, and the temperature rise is not higher than 30 ºC Technical performance index analysis table: The vibrating solid-liquid separator has complete functions and strong pertinence. The design of the whole machine organically combines the sewage pumping system, vibration system, slag conveying extrusion system and automatic flushing system, improves the sewage treatment capacity and treatment effect, and can squeeze the feces and dregs dry, which is easy to use and creative. Its creativity and advanced nature are: 1. It is designed as a vibration separation mode, with fast solid-liquid separation speed and large treatment capacity.

It is unique in the design and material selection of vibrating screen and its supporting column. It can be used in the harsh environment with strong corrosion and high humidity, and has low noise. 3. The screw feeding extrusion system is used to extrude the separated fecal residue twice to reduce the water content of the fecal residue, and the extrusion sewage outlet is set before the slag discharge, which can ensure that the water content of the separated fecal residue is less than 60%, and the dry and wet can be adjusted according to the user's breeding cleaning mode. The performance is better than that of other similar products at home and abroad; the moisture content adjusting frame at the outlet of the manure can adjust the moisture content of the manure to achieve the ideal fermentation humidity of Zui. 4.
