Problems solved by technology

In this way of cleaning, the drive motor of the filter element is installed outside the body. In order to avoid liquid outflow, a mechanical dynamic seal must be set between the body and the motor. In actual operation, this kind of moving mechanical seal is difficult to achieve. , even if implemented, there is still a hidden danger of leakage

Embodiment 1

[0017] see image 3 , Figure 4 , the novel method for removing diatomite of the present invention is that a plurality of spray pipes 3 are densely distributed in the circumferential direction on the inner wall of the filter body casing 1. The spray pipe 3 sprays and rinses the diatomaceous earth sequentially. The specific control method is electric control, that is, a solenoid valve 7 is installed on each spray pipe 3, and multiple solenoid valves 7 are controlled to open and close sequentially through the PLC in the prior art, so as to realize the sequential spraying of multiple spray pipes 3. Drain and rinse. The water jets sprayed from the plurality of spray pipes 3 successively exert force on the diatomite coating 4, so that the mixture of flushing water and diatomite forms a vortex, thereby rinsing the diatomite clean.

Embodiment 2

[0019] see image 3 , Figure 4 , the novel method for removing diatomite of the present invention, outside the filter body, on the inner wall of 1, a plurality of spray pipes 3 are densely distributed in the circumferential direction. The spray pipe 3 sprays and rinses the diatomaceous earth sequentially. The specific control method is mechanical control, that is, through a mechanical structure (such as a rotary valve in the prior art), multiple spray pipes 3 are sequentially started to work. After the spraying work of the previous spray pipe is completed, the next spray pipe Start to work, and now that shower pipe 3 in the front stops working, thereby realizing the successive spraying and flushing of multiple shower pipes 3. The water jets sprayed from the plurality of spray pipes 3 act successively on the diatomite coating 4, so that the mixture of flushing water and diatomite forms a vortex, thereby rinsing the diatomite clean.

Abstract

The invention discloses a new method for removing diatomite. A plurality of spraying pipes are densely distributed on the inner wall of a filtering machine body shell along the peripheral direction; and when the diatomite is removed, a filtering element keeps static and the plurality of spraying pipes are controlled to spray and wash the diatomite in sequence according to the order. Compared with the prior art, the filtering element is designed to be static; electric control or mechanical control is used for enabling the spraying pipes to spray and wash in sequence and the mixture of used washing water and the diatomite forms vortex, so that the washing effect is good; and the difficulty of mechanical dynamic sealing is completely solved, the structural design is simplified and the operation is relatively simple and convenient.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a new method for removing diatomite. Background technique [0002] In the field of filtration, there is a diatomite filter that works by pre-coating the filter aid (diatomaceous earth) on the filter element, forming a uniform layer of diatomite coating on the filter element, and the liquid to be filtered , under the pump pressure, through the pre-coating into the collection chamber, particles and macromolecules are trapped on the pre-coating, thus completing the filtration work. Before the filter is used for the next time after one job, the previous filter aid diatomaceous earth must be removed and replaced with new diatomaceous earth for the next filtration. [0003] The removal of diatomite is generally done by washing with water. If you want to wash the diatomite clean, you must ensure that every part of the filter element is rinsed with water. In the prior art, by contro...
