Problems solved by technology

[0006] In view of this, the purpose of the present invention is to provide a new type of extracorporeal circulation cleaning and regeneration filter, through which the filter material can be subjected to high-intensity cyclic backwashing to completely regenerate the filter material, and solve the problems of previous filter equipment. Difficult backwashing and regeneration of the filter material, poor pollution resistance, resulting in short service life of the filter material and low filtration accuracy, increasing the backwashing strength solves the problem that the incoming liquid containing dirt that is difficult to separate from the filter material cannot be treated by filtration , expand the scope of application of the filter, deepen the depth of the filter bed to the greatest extent, and improve the processing capacity and processing accuracy

Embodiment 1

[0039] Such as figure 1 As shown, the filter in this embodiment includes a filter body 1 and an extracorporeal cleaning cycle device 2 . The filter body 1 includes a filter tank body 11 , a filter material 12 , an upper pipeline 13 and a lower pipeline 14 , and the filter tank body 11 includes an upper head 111 , a cylinder body 112 and a lower conical head 113 . The upper head 111 , the cylinder body 112 and the lower conical head 113 are connected to each other in order from top to bottom to form the filter tank body 11 . On the upper end of the canister body 11 is provided a canister oil discharge pipe 114 . The filter material 12 includes a top filter material 121 , a middle filter material 122 , a bottom filter material 123 (or more layers of filter material) and a mixed filter material 124 . These filter materials are sequentially placed in the filter tank body 11 from top to bottom to filter the fluid to be filtered passing through the filter tank body 11 .

Embodiment 2

[0049] The filter in the second embodiment includes a filter body 1' and an extracorporeal cleaning circulation device 2'. The filter body 1' has the same structure as the filter body 1 in the first embodiment except for the upper pipeline, and the same parts are here Do not repeat. The upper pipeline in this embodiment is represented by 13'; the extracorporeal cleaning and circulatory device in this embodiment is also different from the extracorporeal cleaning and circulatory device 2 in Embodiment 1, and the extracorporeal cleaning and circulatory device in this embodiment is represented by 2' To represent. The upper pipeline 13' and the extracorporeal cleaning and circulation device 2' in the second embodiment will be introduced respectively below.

[0050] Such as figure 2 As shown, the upper pipeline 13' includes a liquid inlet pipe 131' and a water distribution baffle 132', the liquid inlet pipe 131' is inserted from the top of the filter tank body 11, and the water d...

Embodiment 3

[0056] The third embodiment is basically the same as the second embodiment, and the difference between the third embodiment and the second embodiment will be described in detail below. Embodiment 3 On the basis of Embodiment 2, the guide umbrella 21', the material guide pipe 22' and the jet device 23' are canceled, and the jet guide hole 28' is set along the longitudinal center position of the central water collecting tube 142, and the backwashing into One end of the water pipe 26' facing the inside of the filter tank body 11 is provided with an inlet nozzle 29', and the spraying direction of the inlet nozzle 29' is directly opposite to the inlet end of the jet guide hole 28'.

[0057] The operation processes of the third embodiment and the second embodiment are basically the same, and will not be repeated here.

Abstract

The invention relates to a filter. The filter comprises a filter body and an external cleaning circulating device, wherein the filter body comprises a filter tank body, a filter material, an upper pipeline and a lower pipeline; the filter material is arranged in the filter tank body, the upper pipeline comprises a liquid inlet pipe, the lower pipeline comprises a water outlet pipe, the external cleaning circulating device comprises an external cleaning device, a backwashing feeding pipe, a backwashing water outlet pipe and a backwashing pump, and the external cleaning circulating device is connected with the filter body. According to the filter, as the external cleaning circulating device is arranged, the filter material can be cycled, back-washed and regenerated thoroughly with high strength, and the difficulties that the filter material of the filter equipment has short service life and low filtering precision due to backwashing regeneration difficulty and poor anti-contamination capability of the filter material can be solved, the backwashing strength can be improved, and a problem of the prior art that the liquid containing sewage difficult to be separated from the filter material cannot be filtered is solved.

Description

technical field [0001] The invention relates to a filter device for liquid treatment, in particular to an ultra-deep bed filter for extracorporeal circulation cleaning, and belongs to the technical field of environmental protection. Background technique [0002] In liquid treatment, the filter equipment that uses solid particle filter material to form a filter bed for filtration and separation is used as one of its terminal treatment equipment. Because of its high efficiency and reliability, the filter material can be used for backwash regeneration and is widely used. However, in the past filters, it was difficult to backwash the filter material, which made the regeneration of the filter material incomplete, especially when the incoming water contained colloids with strong adhesion to the filter material, such as polymers, and heavy oil with high viscosity. When there are dirt and other impurities on the surface of the filter material, the backwashing intensity of the existi...
