Self-cleaning filter with uninterrupted feeding effect

Abstract

The invention provides a self-cleaning filter with an uninterrupted feeding effect. The filter comprises a shell, a plurality of filtering ring plates and a slag discharging pipe, wherein a feeding hole is formed in a side wall of the shell; a central pipe is arranged in the shell; a filtering liquid discharging hole is formed in a part, positioned outside the shell, of the central pipe; all filtering ring plates are of a circular shaped hollow cavity structure; the plurality of filtering ring plates are spaced up and down and arranged at the periphery of the central pipe in a sleeving manner; inner ring surfaces of all filtering ring plates are tightly adhered to a peripheral surface of the central pipe; material holes which are communicated with one another are formed in both of the inner ring surfaces of the filtering ring plates and the peripheral surface of the central pipe; the slag discharging pipe is positioned on one side of the central pipe; a lower end of the slag discharging pipe extends out of the shell; a slag discharging hole is formed in a part, positioned outside the shell, of the slag discharging pipe; the periphery of the slag discharging pipe is provided with a plurality of suction nozzles from top to bottom in a communication manner; each suction nozzle is positioned between two filtering ring plates which are adjacent to each other up and down; the suction nozzles are close to the filtering ring plates. According to the self-cleaning filter with the uninterrupted feeding effect disclosed by the invention, under a condition of uninterrupted charging and discharging, a self-cleaning process can be quickly completed.

Description

technical field [0001] The invention belongs to the technical field of filtration, and in particular relates to a self-cleaning filter with uninterrupted feeding. Background technique [0002] For the fully automatic filtration system that needs to be regenerated by backwashing, in order to ensure continuous and stable production, a configuration mode with two filters in a filter device is generally used. In normal operation, there is actually only one filter. The other one is waiting for standby, but it needs a large number of valves, instruments, complex PLC system and many supporting auxiliary equipment, so the cost of the device is high, the operation requirements are high, and the floor space is large. Therefore, it is not suitable for users with good raw materials and limited space. Moreover, the existing filtration system does not have an inspection system, or the slag is discharged by external power, which consumes a lot of energy and is inconvenient to use. Conte...

[0002] For the fully automatic filtration system that needs to be regenerated by backwashing, in order to ensure continuous and stable production, a configuration mode with two filters in a filter device is generally used. In normal operation, there is actually only one filter. The other one is waiting for standby, but it needs a large number of valves, instruments, complex PLC systems and many supporting auxiliary equipment, so the cost of the device is high, the operation requirements are high, and the floor space is large.

Therefore, it is not suitable for some users with good raw materials and limited space.

Moreover, the existing filtration system does not have an inspection system, or the slag is discharged by external power, which consumes a lot of energy and is inconvenient to use
