Abstract

The utility model discloses an improved sand washer for an active sand filter. The improved sand washer comprises an outer cylinder, a middle cylinder and an inner cylinder which form sand washing channels; the middle cylinder is an open frame body which is formed by uniformly arranging three or more than three cylindrical rods in a circular trace; a plurality of circles of turning plates are arranged on each of the inner circumferential wall of the outer cylinder, the outer circumferential wall of the inner cylinder and the inner and outer circumferential walls of the frame body of the middle cylinder; and the turning plates are inclined downward. The improved sand washer comprises the three cylinders; the circumferential wall of each cylinder is provided with a plurality of circles of the inclined turning plates; and dirt sand can be continuously compacted to be scattered by the turning plates, so that the sand washing efficiency is greatly improved, and the sand washing amount is increased.

Description

A kind of improved active sand filter is used sand-washing device

Technical field

The utility model relates to the corollary apparatus on a kind of active sand filter of the usefulness of disposing of sewage, the sand-washing device on especially a kind of improved active sand filter.

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.The performance of sand-washing device depends on the cross section of the washed-out sand passage of sand-washing device, the internal structure of washed-out sand passage.In general, the washed-out sand channel cross-section of sand device is big more, but the washed-out sand amount is big more, and relatively, the washed-out sand effect is poor 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, and promptly the cleanliness factor of sand is high more, but also gets over easy blocking.The sand-washing device that uses at present, the problem that ubiquity washed-out sand amount is little has directly had influence on the performance and the treating capacity large scale development of active sand filter; Chinese patent ZL200920240954.4 discloses the sand-washing device that a kind of active sand filter is used, outer through being provided with, in, interior three waveform cylindrical shells; Make it form the washed-out sand binary channels, increased the washed-out sand amount, and effectively increased the washed-out sand effect through the waveform cylindrical shell; But because cylindrical shell is set to waveform, difficulty of processing increases, and the amplitude of wave is difficult to satisfy the washed-out sand needs; And wherein tube is closed cylindrical shell; The washed-out sand aisle spare is reduced, and the washed-out sand amount also reduces thereupon, and washed-out sand efficient and washed-out sand amount still have much room for improvement.

Summary of the invention

The utility model provides a kind of washed-out sand amount big to above-mentioned deficiency, the sand-washing device on the effective improved active sand filter of washed-out sand.

The utility model is in order to solve the problems of the technologies described above; Following technical scheme is provided: a kind of improved active sand filter is used sand-washing device; Comprise urceolus, middle tube, inner core, constitute the washed-out sand passage between the three, it is characterized in that described middle tube is three or three open frame bodies that above cylindrical rod is uniformly distributed with to justify track; Be respectively arranged with some circle turnover panels on urceolus inner peripheral wall, inner core outer circle wall, the middle tube frame body inside and outside circle perisporium, described turnover panel is all downward-sloping.

Be arranged between inner core circle wall and the urceolus circle wall through this kind downward-sloping turnover panel is set, the dirty sand that filters behind the sewage gets between urceolus and the inner core, in the decline process, constantly collides with wall through the downward-sloping turnover panel of multilayer and breaks up; And washed by the rinse water that gets into from the passage lower end; Reach the clean purpose of dirty sand, also be provided with the middle tube that the inside and outside circle perisporium all has turnover panel between sand-washing device urceolus and inner core, the turnover panel on turnover panel on the inner/outer tube circle wall and the middle tube circle wall is staggered up and down; Because middle tube is three or three open frame bodies that above cylindrical rod is uniformly distributed with to justify track; So do not take the inner space of washed-out sand passage, the washed-out sand amount is improved greatly, the turnover panel setting meets the washed-out sand principle of dynamics in the washed-out sand passage; Thereby the washed-out sand amount of whole sand-washing device in the unit interval increases greatly.

As the further improvement of the utility model, the turnover panel on the same cylindrical shell circle wall evenly distributes at interval, through the equally distributed turnover panel in interval, reasonably distributes the washed-out sand passage, improves washed-out sand efficient.

As the further improvement of the utility model, the turnover panel on turnover panel on the inner/outer tube circle wall and the middle tube circle wall is staggered up and down, makes an interior washed-out sand tunnel-shaped become well-bedded washed-out sand passage through this kind setting, has improved washed-out sand efficient.

Further improvement as the utility model; Turnover panel on urceolus circle wall and the inner core circle wall is symmetrical set; Turnover panel on the middle tube inside and outside circle perisporium is symmetrical set, and through this inner space that reasonable arrangement washed-out sand passage is set, makes dirty sand be easier to break up with the barrel collision.

Preferred as the utility model, the cylindrical rod of tube frame body is provided with the 3-6 root in the formation.Make being installed on the cylindrical rod that inside and outside turnover panel can be more firm through this kind setting, few to the greatest extent again simultaneously washed-out sand channel space that takies.

Preferred as the utility model, the downward-sloping angle of turnover panel is preferably 30 °-60 °, make dirty sand more easily continuous bump beat spread get into down under one deck inclination turnover panel, raising washed-out sand efficient and washed-out sand flow.

The utility model is provided with some circle inclination turnover panels through three cylindrical shells are set on the circle wall of each cylindrical shell, constantly dirty sand bump is broken up through turnover panel, has improved washed-out sand efficient and washed-out sand amount greatly.

The specific embodiment

Embodiment 1: a kind of improved active sand filter is used sand-washing device; Comprise urceolus 1, middle tube 2, inner core 3; Constitute the washed-out sand passage between the three; It is characterized in that described middle tube 2 is three or three open frame bodies that above cylindrical rod 21 is uniformly distributed with to justify track, be respectively arranged with some circle turnover panels 4 on urceolus 1 inner peripheral wall, inner core 2 outer circle walls, the middle tube 2 frame body inside and outside circle perisporiums, described turnover panel 4 is all downward-sloping.Turnover panel 4 on the same cylindrical shell circle wall evenly distributes at interval.Turnover panel 4 on turnover panel 4 on inner/outer tube (1, the 3) circle wall and middle tube 2 circle wall is staggered up and down.

Embodiment 2: use sand-washing device with reference to a kind of improved active sand filter of embodiment; Turnover panel 4 on described urceolus 1 circle wall and inner core 3 circle wall is symmetrical set; Turnover panel 4 on the middle tube 2 inside and outside circle perisporiums is symmetrical set; The cylindrical rod 21 of tube 2 frame bodies is provided with the 3-6 root in the formation, and turnover panel 4 downward-sloping angles are 30 °-60 °.
