Description

Water treatment pool

Technical Field

The utility model relates to a water clarification plant, specifically speaking relates to the water treatment pond.

Background

Referring to fig. 1, fig. 1 is a schematic lower half-plane view of a lateral flow water treatment tank, in which a reaction zone, a water distribution zone, a sedimentation zone and a water collection zone are defined by a tank wall 101, a tank wall 102, a tank wall 103 and a tank wall 104, the reaction zone is on the left side of a partition wall 110, and the water distribution zone 121, the sedimentation zone 122 and the water collection zone 123 are on the right side. When viewed from the upstream and downstream directions of the water flow, raw water enters the reaction zone after passing through the flocculation tower 109, then enters the water distribution zone 121, the sedimentation zone 122 and the water collection zone 123 in sequence, and finally purified water flows out from the water outlet pipe 111. Among them, the partition wall 105, the partition wall 106, the partition wall 107, and the partition wall 108 are half-height walls.

Referring to fig. 2, fig. 2 is a sectional view taken along line a-a of fig. 1, a horizontal pipe settling device 124 is installed on the top of the half-

height walls

106 and 107, and raw water is passed through the horizontal pipe settling device 124 to flow to the water collecting area 123.

Referring to fig. 3, fig. 3 is a sectional view taken along line B-B of fig. 1, when raw water flows through the water distribution area 121, the settling area 122 and the water collection area 123 from left to right, sludge and other sediments are continuously collected at the

bottoms

125 and 126 of the water distribution area 121, the bottom 127 of the settling area 122 and the

bottoms

128 and 129 of the water collection area 123. For the purpose of collecting the sediment, the bottom 125, the bottom 126, the bottom 127, the bottom 128 and the bottom 129 are designed in a cone shape, and a sludge discharge branch pipe is arranged at the bottom of the cone and leads to a sludge discharge main pipe at one end.

The water treatment pool adopting the horizontal pipe precipitation device is divided into a forward flow mode and a lateral flow mode according to a water flow mode, the mud valve of the forward flow horizontal pipe can be arranged at two ends, and the mud valve of the lateral flow horizontal pipe can be arranged at only one end. The sludge discharging effect is not ideal when the sludge discharging mode is adopted for the large-scale horizontal pipe sedimentation tank, and the sludge discharging pipes are inconvenient to arrange. Therefore, a special mechanical sludge discharge device is required to be adopted in the large horizontal pipe sedimentation tank.

Because of the mud moisture content in sedimentation zone is more than 95%, traditional mud scraper can arouse the disturbance of sediment mud when scraping mud, breaks up sediment mud, makes its mud effect of arranging not good. To current high-efficient sedimentation tank of horizontal pipe, sedimentation tank's efficient must have better row mud effect, otherwise influences quality of water.

In the traditional mud scraper, no matter a reciprocating mud scraper, a chain mud scraper and an underwater single-rail mud scraper, one mud scraper must be arranged in each partition pool, so that mud can not be scraped in each partition simultaneously, and the investment cost and the maintenance cost are greatly increased.

the utility model also aims to provide a water treatment pool with small mutual interference of all the structural partitions during mud scraping.

In order to achieve the main purpose, the utility model provides a water treatment tank has multichannel parallel arrangement's partition wall in the pond, and the multichannel partition wall separates the bottom of the pool part for a plurality of sediments district of gathering. A strip-shaped shaft passing window penetrating through the partition walls is formed in the positions, close to the bottom surfaces, of the multiple partition walls; a long shaft penetrates through all the shaft passing windows, and a mud scraper fixed on the long shaft is arranged between two adjacent partition walls; the long shaft can reciprocate along the length direction of the shaft window.

It is thus clear that by the above scheme, the utility model discloses set up the through-axle window of rectangular shape bottom the partition wall, adopted a major axis to pass all partition walls, the segmentation sets up the mud scraper on the major axis, makes each mud scraper set up in each subregion correspondingly, and like this, the reciprocating motion of major axis just can scrape mud to the deposit district of each subregion simultaneously.

The further proposal is that the sediment accumulation area is provided with a straight bottom surface, and the water treatment pool of the utility model is a forward flow pool or a lateral flow pool.

In order to realize the other purpose of the utility model, a further proposal is that a separating curtain for plugging the shaft-passing window is arranged on the shaft-passing window; the long shaft passes through the separating curtain. Therefore, in the reciprocating operation process of the long shaft, sediment phases in sediment accumulation areas on two sides of the shaft passing window can not interfere with each other, and especially, sludge in an upstream subarea cannot improperly flow into a downstream subarea through the shaft passing window.

The further proposal is that the curtain is a bidirectional zipper or a facing fiber brush or a facing flexible sealing body.

The long shaft can rotate around the axis of the long shaft in a reciprocating mode by an angle, so that the mud scraping plate has a larger water facing area when running towards the mud discharging pipe and has a smaller water facing area when running away from the mud discharging pipe. Thus, the sludge can be more quickly scraped to the end where the sludge discharge pipe is located.

The mud scraper is characterized in that the mud scraper is two wing plates fixed on the long shaft, and an included angle is formed between the two wing plates when viewed from the axial section of the long shaft. This scheme makes mud scraping efficiency higher

The other further proposal is that the mud scraping plate is a column panel fixed on the long shaft, and the generatrix of the mud scraping surface of the column panel is a quadratic curve when viewed from the axial section of the long shaft. This scheme makes the mud scraping efficiency higher.

A still further proposal is that when the mud scraper operates, a mud scraping gap is kept between the lower edge of the mud scraper and the bottom surface. The existence in this clearance can prevent on the one hand that the mud scraping plate reduces life because of producing the friction with the bottom surface, and on the other hand can effectively strike off the mud on the bottom surface.

Still a further aspect is a screed having a rigid frame with a wire mesh secured therein.

Still a further solution is that the long shaft is connected at both ends of the slider using a coupling loop, and the slider slides on a track in the through-shaft window. The advantage of this scheme is can select for use the major axis of different length according to the pond shape of difference.

The mud scraper 131 of this embodiment has a rigid frame and a steel wire mesh fixed in the rectangular frame, and the mesh of the steel wire mesh is preferably small enough to achieve the mesh of water and sludge.

Third embodiment

Referring to fig. 10, the present embodiment is characterized in that the curtain is made of an opposite flexible sealing body 142, and the opposite flexible sealing body 142 may be made of a silica gel or a latex sheet, which also has the effect that when the long shaft 130 runs along the length direction of the strip-shaped through-shaft window 1601, the flexible sealing body 142 at the place where the long shaft 130 is located is avoided due to extrusion, and the front and rear flexible sealing bodies 142 are all in a normal state to close the through-shaft window 1601, thereby realizing the isolation of sludge in the upstream and downstream areas.
