The characteristics of the mud produced in the water washing process of sand making plants, sand washing plants, and gravel yards depend on its composition and are related to local geological conditions. The general characteristics are that the mud is yellowish in appearance, uniform and viscous, an
Rural domestic sewage is mainly domestic waste and human excrement. Generally, it does not contain toxic substances, but often contains nutrients such as nitrogen and phosphorus, as well as a large number of bacteria, viruses and parasite eggs. Some villages do not have drainage channels and sewage
Grease and liquid separation equipment is mainly used in food processing plants to filter and separate oil residue and water, so that the filtered oil is clear and free of residue and foam, reaching the standard of edible oil. This oil and liquid separation equipment is suitable for filtering: rapes
Oilfield mining requires about 2-3 tons of water injection for each ton of crude oil produced. The water content of the produced oil continues to increase, resulting in the production of a large amount of oilfield wastewater, and the composition is complex. In addition to containing soluble salts an
The small diaphragm filter press is a laboratory diaphragm filter press specially made for small tests and pilot tests. Its pressing forms are divided into gas air, inert gas press and liquid water and oil press, which can meet the needs of different industries. According to customer needs, the pres
Small laboratory filter presses are generally used in laboratories for experimental filtration. For example, some colleges and universities or various research institutes of the Chinese Academy of Sciences, as well as key laboratories of the national project type, are all selected in the use of filt
Basic overview of laboratory small diaphragm filter press:The laboratory small diaphragm filter press is a special laboratory diaphragm filter press specially made for small tests and pilot tests. Its pressing forms are divided into gas (air, inert gas) pressing and liquid (water, oil) pressing, whi
Sudong Chemical Machinery Co., Ltd. is a long-established filter press manufacturer and research company with rich industry experience. In view of the phenomenon that some materials will volatilize toxic and harmful gases when filtering, which will harm the health of operators and pollute the environment, it has launched The following two filter cloths solve this environmental problem.
Many manufacturers in the sewage treatment industry have problems with outdated equipment and outdated equipment, resulting in high labor intensity and unsatisfactory treatment effects. Therefore, equipment needs to be replaced or upgraded. Many manufacturers choose to use automatic filter presses.
In the working state of the filter press, the suspension will definitely occur. If the sales promotion is not in place when it is suspended, it will have a serious impact on subsequent work. Through observation and analysis during the operation of the machine, it is found that this phenomenon occurs because the feed tube of the quick-opening diaphragm filter press uses a steel ring rubber tube. Under the action of pressure filtration, the pipeline itself will form a reaction. The force is applied to the pressure plate, which offsets the force of the oil cylinder to a certain extent, causing the pressure plate to rebound, and the push pin is not in place when it is stopped, and the machine fails. Based on this situation, the following improvement plan is proposed: the direction of the feeding hose and protective cover of the quick-opening membrane filter press is adjusted to a certain extent, specifically, it is turned 180° on the original basis, and the clockwise bending becomes counterclockwise. bending. In this way, the reaction force in the feed pipe will not only not offset the force of the cylinder, but also strengthen the pressing operation.
