Embodiment Construction

[0063] For the filtration of technical water supply commonly used in hydropower plants, the outlet pressure of the filter is 0.25MPa, the outlet flow rate is 1000m3 / h, and the filter particle diameter is 1mm.

[0064] The cylinder shell (5) in this filter Figure 2 is made of standard carbon steel with a thickness of 10mm rolled into a seamless steel pipe with a diameter of 1200mm and a height of 1200mm; the upper cover (6) and the lower cover of the housing in Figure 2 (7) All are made of standard carbon steel with corresponding thickness, the diameter and height are enlarged according to the size of the drawing, and the 8 bolts are Φ12mm standard bolts; Fig. 3 The filter element support (16) and the filter element upper cover (17) of the rotating filter element body 1. The lower cover (18) of the filter element body is made of non-toxic PVC plastics. The diameter of the upper and lower covers and the outer diameter of the cylindrical filter screen (20) are 800mm, and the outer...

Abstract

The invention is concerned with a batch self-flush filter, relating to filter shell, revolving filter core body, self flush implement and batch control valve. The filter shell is made up of cylinder type of crust, upper cover, down cover and bolt of splint, and the filter core body is a cylinder made of core bracket connecting with upper and down covers through bolts. The filer net is on outside of the bracket, and the filter core body connects with filter shell in type of bearing. The down cover of filter core body is made up with impeller as a whole and crescent type of self-flush implement insert on the upper cover of filter shell and the groove of splint. The different pressure control valve connects with upper cover, main press and assistant press shell, dirt excluding shell and bolt of down cover. The press film connects with bolt, sleeve and control head through screw thread. The assistant press pipe and main press pipe connect with inner and outside press pipe of shell respectively. It completes filtration and self- flush of filter core by the energy of liquid owning press without additional power in simple installation and convenient use.

Description

1. Technical field [0001] The invention relates to a filtering device, in particular to a device for separating small-volume solid particles mixed in liquid fluid, used for small solid particles mixed in water and small solid particles mixed in light oil Intermittent self-flushing filters for filtering liquid pressurized fluids such as particles. 2. Background technology [0002] Now on the market, there are various types of filters with their own characteristics. They can be summarized into the following two types: ordinary filters, which need to clean the filter screen after working for a period of time, and have been gradually eliminated; The filter with net automatic flushing needs an external power supply. Under the drag of the motor, it rotates and flushes and discharges the dirt through the electronically controlled valve or manual intervention. Because this kind of filter requires an external power supply, its cost and scope of use are all subject to relatively larg...
