Abstract

The utility model provides a micropore filtering pipe water collecting device with a washing device. In the utility model, the existing micropore filtering pipe water collecting device is provided with the washing brush which is composed of a brush head and a brush. The brush is arranged on the brush head, the number of the brush is the same as the number of the micropore filtering pipe, and the brush can be inserted into the micropore filtering pipe to washing the pipe wall of the micropore filtering pipe. The reciprocating movement of the washing brush is driven by a reciprocating movement mechanism. The utility model can effectively clear to the residue on the inner wall of the micropore filtering pipe, which improves the filtration efficiency and the production quantity, and extends the back flushing cleaning period. Besides, the utility model has the advantages of simple structure and easy use.

Description

Microhole filtering pipe with washing device

The utility model belongs to a kind of improved device for fetching water, particularly a kind of microfiltration tube device for fetching water with washing and brushing device.

The device for fetching water that microfiltration tube is housed is proposed by me, and has applied for patent.This device for fetching water is made of collecting chamber, mesh outer cover, porous barrier and microfiltration tube, and its design is with mesh outer cover interception floating thing and bulk impurity, makes microfiltration with built-in microfiltration tube, draws water by water pump and carries out work.This device for fetching water can overcome the shortcoming that existing device for fetching water can not filter silt particle, suspension and fine impurities effectively, reduces turbidity, simplification postprocessing working procedures, saving floor space and the investment of source water significantly.After adopting microfiltration tube, along with the increase of time, inside pipe wall will apply one deck body refuse, must be in advance could guarantee filtration everything goes well with your work to carry out to remove.Former solution is with the compressed air recoil, carries out but will suspend to filter.In addition, consider that for well, can influence output but make like this with short the blanking time of recoil from improving filter efficiency; If prolong the blanking time of recoiling, the body refuse that is attached in the pipe will inevitably increase, and filter efficiency reduces, and the required recoil time can increase, and reduces output equally, the deficiency of this above-mentioned just device for fetching water.

The purpose of this utility model is to overcome the problem of the existing above-mentioned existence of microfiltration tube device for fetching water, and a kind of simple possible is provided, and need not suspend the microfiltration tube device for fetching water that filtration can be removed the band washing and brushing device of body refuse in the pipe.

Task of the present utility model is achieved in that with to have the microfiltration tube device for fetching water identical, it includes collecting chamber, microfiltration tube, porous barrier and outlet pipe, improvements are also to set up one by brush be loaded on that quantity equates with microfiltration tube on the brush, can be inserted to the cleaning brush that brush constituted of scrubbing its tube wall in the microfiltration tube at the axial end portion of microfiltration tube, and moving back and forth of this cleaning brush is that reciprocating mechanism by with the brush binding drives.

From above-mentioned improvement project as can be known, owing to increased micro porous filtration tube wall washing and brushing device, by intermittently or brush is back and forth moved in pipe, be attached to just obviously minimizing of body refuse on the tube wall, thereby improve filter efficiency and productivity ratio effectively, and can prolong the recoil cleaning frequency greatly, even might cancel the recoil operation.In addition, the utility model also has advantage simple in structure, easy to use.

In the accompanying drawing, (1) is header tank, and (2) are microfiltration tube, and (3) are porous barrier, and (4) are outlet pipe, and (5) are brush, and (6) are brush, and (7) are reciprocating mechanism.

The perpendicular embodiment of putting of the utility model as shown in Figure 1, its reciprocating mechanism (7) has two kinds of embodiments: one is made up of motor (8), reduction box (9), bent axle (10), connecting rod (11) and guide rod (12) as shown in Figure 3; It is made up of cylinder (13), Pneumatic valve (14) and air compressor (15) two as shown in Figure 4.The horizontally-arranged embodiment of the utility model as shown in Figure 5, its reciprocating mechanism (7) is made up of pull strings (16), guide roller (17) and the hoist engine (18) that lie on microfiltration tube (2) the two ends brushes (6), and pull strings (16) are around on the hoist engine (18) through guide roller (17) again.It is the positive and negative rotation that utilizes travel switch control hoist engine (18), and it is reciprocating to make pull strings (16) drag cleaning brush back and forth, scrubs the inwall of pipe.Reciprocating mechanism of the present utility model (7) can be used with a plurality of device for fetching water, for the perpendicular device for fetching water of putting, its embodiment as shown in Figure 6, for horizontally-arranged device for fetching water, its embodiment is as shown in Figure 7.
