Description

The core invention of this conical column type packet switching filter is aimed at the shortcomings of the existing technology. It provides a double-column switchable screen changer, which adopts a switching method to change the screen and packing. The function of the tapered cylinder is to have high pressure, good sealing and no leakage, and manufacturing cost. The advantages of less, god filtering effect, convenient operation, and small pressure fluctuation, can achieve continuous striping when changing the screen. A filter column driven by a telescopic drive device is provided in the filter chambers, a switching valve is provided in the screen changer box between the two filter chambers, and the switching valve is provided with a communication hole and a communication hole distributed along the axial direction. Hole 2, when the switching valve reciprocates in the axial direction, the two filter chambers are respectively communicated with the inlet through the communicating hole 1 and communicating hole 2, and are exchanged when changing the screen. The two outlet channels are designed with interlocking internals. The valve prevents the two flow passages from passing through each other when changing the net. The appearance is unique and the use value is higher.

Technical Parameters

Advantages

1.High-efficiency and stable filtration. The tapered column design makes the flow field uniform, and the material flow is stable with small fluctuations during screen changing.

2.Convenient and rapid screen changing. The screen-wrapped switching operation is simple, shortening the screen changing time and improving production efficiency.

3.Good sealing performance. The high-performance sealing structure prevents material leakage under high temperature and high pressure.

4.Large filtration area. It provides a large filtration area within a limited space, improving the ability to intercept impurities and reducing the frequency of screen changing.

5.Strong and durable structure. Made of high-quality alloy materials, through precision machining and heat treatment, it has high strength and a long service life.

6.Wide range of applications. It is adaptable to various materials and processes and can select different screens as needed.

7.Simple operation and maintenance. With an advanced control system and interface, the operation is simple and it is convenient for daily maintenance.

8.High safety performance. Multiple safety protection devices ensure the safety of personnel and equipment.
