Abstract

The utility mode discloses a sand washer for an active sand filter, which belongs to the technical field of sewage treatment equipment. The sand washer comprises a waved outer barrel (1) and a waved inner barrel (2) arranged at the inner side of the outer barrel (1), wherein a sand washing channel is formed between the outer barrel (1) and the inner barrel (2). The sand washer is characterized in that a waved middle barrel (3) is arranged between the outer barrel (1) and the inner barrel (2), so that the sand washing channel forms an inner channel (4) and an outer channel (5). In the utility model, the sand washing channel adopts double channels, therefore, the sand washer has large sand washing quantity, good sand washing effect, high cleanliness of washed sand, and can greatly improve the water treatment capacity and water treatment efficiency of the active sand filter.

Description

The sand-washing device that a kind of active sand filter is used

Technical field

The utility model is the corollary apparatus on the active sand filter of usefulness of disposing of sewage, and is a kind of sand-washing device that is used on the active sand filter specifically.

Background technology

Sand-washing device is a requisite corollary apparatus on the active sand filter, and its effect is that the dirty sand washing behind the filtration sewage is clean.Usually, the washed-out sand channel cross-section of sand-washing device is big more, but the washed-out sand amount is big more, but the washed-out sand effect is poor more, and promptly the cleanliness factor of sand is low more; And the washed-out sand channel cross-section of sand-washing device is more little, but the washed-out sand amount is more little, but the washed-out sand effect is good more, and promptly the cleanliness factor of sand is high more, but also easy more obstruction.The sand-washing device that uses all is the single channel sand-washing device at present, and general washed-out sand amount is less, directly influences the performance and the maximization of equipment.

The utility model content

In order to solve the little and washed-out sand amount of washed-out sand amount that single channel sand-washing device in the prior art exists if the technical problem that big cleanliness factor will be low, the utility model provides a kind of novel sand-washing device, its washed-out sand amount is big, washed-out sand is effective, the cleanliness factor height of sand can improve the water treatment capacity and the water treatment efficiency of active sand filter greatly.

The utility model is achieved by the following technical solution: the sand-washing device that a kind of active sand filter is used, the waveform inner core that it comprises corrugated urceolus and is located at the urceolus inboard, constitute the washed-out sand passage between urceolus and the inner core, it is characterized in that: between urceolus and inner core, be provided with corrugated intermediate cylinder, make the washed-out sand passage constitute internal channel and outer tunnel.

The utility model is divided into internal channel and outer tunnel by between inner core and urceolus intermediate cylinder being set with the washed-out sand passage.Filter the dirty sand behind the sewage, the upper end from internal channel and outer tunnel enters respectively, constantly breaks up with the conduit wall collision in the decline process, and is washed by the rinse water that is entered by the lower end from internal channel and outer tunnel, reaches clean purpose.Because two passages carry out washed-out sand simultaneously in the washed-out sand process, thereby the washed-out sand amount of whole sand-washing device in the unit interval increases greatly, and because each passage is equivalent to a single channel, thereby it can effectively guarantee the washed-out sand effect, the sand cleanliness factor height after washing.

The beneficial effects of the utility model are: because washed-out sand passage of the present utility model has adopted binary channels, thereby its washed-out sand amount is big, and because each passage is equivalent to a single channel again, thereby its washed-out sand is effective, the sand cleanliness factor height after washing.The utility model can improve the water treatment capacity and the water treatment efficiency of active sand filter greatly, can be widely used on the active sand filter.

Description of drawings

Fig. 1 is the structural representation of the utility model specific embodiment.

Among the figure, 1, urceolus, 2, inner core, 3, intermediate cylinder, 4, internal channel, 5, outer tunnel.

The specific embodiment

Also in conjunction with the accompanying drawings the utility model is further described below by non-limiting embodiment:

As shown in Figure 1, the sand-washing device that a kind of active sand filter is used, the waveform inner core 2 that it comprises corrugated urceolus 1 and is located at urceolus 1 inboard, between urceolus 1 and inner core 2, be provided with corrugated intermediate cylinder 3, constitute the washed-out sand passage between inner core 2, intermediate cylinder 3 and the urceolus 1 respectively: internal channel 4 and outer tunnel 5.

Filter the dirty sand behind the sewage, the upper end from internal channel 4 and outer tunnel 5 enters respectively, constantly breaks up with the conduit wall collision in the decline process, and is washed by the rinse water that is entered by the lower end from internal channel 4 and outer tunnel 5, reaches clean purpose.

Remainder of the present utility model adopts prior art, does not repeat them here.

The utility model is simple in structure, and the washed-out sand amount is big, and washed-out sand is effective, is particularly suitable for large-scale active sand filter, can improve the water treatment capacity and the water treatment efficiency of active sand filter greatly.

Claims

1. sand-washing device that active sand filter is used, it comprises corrugated urceolus (1) and is located at the inboard waveform inner core (2) of urceolus (1), constitute the washed-out sand passage between urceolus (1) and the inner core (2), it is characterized in that: between urceolus (1) and inner core (2), be provided with corrugated intermediate cylinder (3), make the washed-out sand passage constitute internal channel (4) and outer tunnel (5).
