In industrial production, filter presses are commonly used equipment for the separation of solids and liquids. The design of the feeding system has a crucial impact on production efficiency and separation results. At present, there are two main feeding methods of the filter press: single-stage pump feeding and separate compressor feeding. This article will make a detailed comparison of these two feeding methods, so as to provide a reference for actual production.
1. Single-stage pump feeding system.
The single-stage pump feeding system is a common filter press feeding method, which is mainly composed of a single-stage pump, a feeding pipeline, a distributor, etc. The system transports the material from the storage bin to the feed line of the filter press via a single-stage pump, and then evenly distributes the material to the filter cloth by the distributor. The advantages of the single-stage pump feeding system are that the feeding capacity is large, the feeding pressure is stable, and the degree of automation is high, which can be applied to materials of various particle sizes and properties. In addition, the single-stage pump feeding system also has the advantages of simple structure and convenient maintenance.
However, there are also some drawbacks to the single-stage pump supply system. First of all, for materials with high viscosity or easy to agglomerate, the single-stage pump may cause blockage or uneven feeding. Secondly, for materials that need to be strictly controlled in proportion or composition, it is difficult to achieve accurate measurement and control of single-stage pump feeding. In addition, the energy consumption of the single-stage pump feed is relatively high, which increases the production cost.
2. Separate feeding system for pressure fan.
The separate feeding system of the compressor is a special feeding method of the filter press, which is mainly composed of a compressed fan, an air storage tank, a pneumatic feeder, etc. The system compresses the air through a compressed fan and delivers it to the air storage tank, and then the pneumatic feeder conveys the material to the filter cloth through the air flow. The advantage of the separate feeding system of the compressor fan is that it is suitable for occasions with low pressure requirements, and it has strong adaptability to the material and is not easy to clog. In addition, the initial investment in the separate supply system of the compressor fan is low and easy to maintain.
However, there are also some drawbacks to the compressed fan separate feeding system. First of all, due to the limited conveying capacity of the pneumatic feeder, the feed volume of the system is relatively small. Secondly, the control accuracy of the separate feeding system of the compressor fan is relatively low, and it is difficult to achieve accurate measurement and control. In addition, for materials that require high or low temperature handling, a separate compressor supply system may not be sufficient.
3. Comparison and selection.
The single-stage pump feeding system and the separate compressor feeding system have their own characteristics. In practical applications, the selection should be based on the specific needs and conditions of production. For occasions that require a large amount of continuous feeding, the single-stage pump feeding system has higher stability and efficiency;For occasions with low pressure requirements and strong material adaptability, the compressor fan separate feeding system is more advantageous. In addition, for enterprises with high automation requirements and abundant funds, the single-stage pump feeding system is a better choice;For small and medium-sized enterprises that need to save costs and have limited space, the separate supply system of the compressor fan is more competitive.
In short, when choosing the feeding method of the filter press, the needs and conditions of the actual production should be fully considered, and the pros and cons of various factors should be weighed to make the optimal choice. At the same time, enterprises also need to make equipment selection and investment decisions according to their own development status and long-term planning to ensure that the equipment can meet the needs of future production and create greater value for the enterprise.
