Description

Adapter device

Technical Field

The utility model relates to a dedicated part in water treatment pond settling zone, specifically speaking relates to an adapter device who uses with the cooperation of side direction flow sediment device.

Background

The water treatment tank is used for purifying raw water, and comprises areas such as flocculation, water distribution, sedimentation, water collection and the like, a sludge discharge pipe, sludge discharge equipment and the like. The settling zone is provided with settling devices which are divided into various types according to the settling forms thereof, wherein one type is a lateral flow settling device, and Chinese patent application with publication No. CN102284200A discloses a lateral flow settling device as shown in figures 1 and 2, wherein figure 1 is a three-dimensional structure view of the lateral flow settling device, and figure 2 is a cross-sectional view of the lateral flow settling device in a direction perpendicular to the water flow.

Referring to fig. 1, the direction indicated by the arrow in fig. 1 is the water flow direction. The lateral flow sedimentation device 1 comprises a plurality of groups of parallel inclined plates, each group of inclined plates consists of an upper inclined plate 11 and a lower inclined plate 12, a plurality of partition plates 13 are arranged between the upper inclined plate 11 and the lower inclined plate 12, the upper end edge of each partition plate 13 is intersected with the upper inclined plate 41, the lower end edge of each partition plate 13 is intersected with the lower inclined plate 12, and the intersection lines 17 of the partition plates 13 and the lower inclined plates 12 are on different horizontal planes. The upper and lower

inclined plates

11, 12 and the partition plate 13 form included angles with the horizontal plane, and the partition plate 13 separates a plurality of water flow channels with parallelogram-shaped sections between the upper and lower

inclined plates

11, 12. An elongated row opening 15 extending in the horizontal direction is formed in the lower inclined plate 12 above the intersection line 17 of each partition plate 13 and the lower inclined plate 12. A sludge discharge channel 16 is arranged between the lower inclined plate 12 and the upper inclined plate 11 of the other adjacent group of inclined plates, and if the sludge discharge channel is close to the side wall of the tank body, the sludge discharge channel 16 is arranged between the lower inclined plate 12 and the side wall. A sealing end plate 14 is provided on one end surface or both end surfaces of the sludge discharge passage 16 in the water flow direction.

Referring to fig. 2, the partitions 13 divide the space between the upper and lower

inclined plates

11, 12 into a plurality of water flow passages having a semi-closed parallelogram shape in cross section. When water flows through a water flow channel in the sedimentation device, suspended matters are continuously precipitated under the action of self gravity and slide downwards along the lower inclined plate 12 and the partition plate 13, enter the sludge discharge channel 16 from the discharge port 15, then enter the sludge discharge hopper from the sludge discharge channel 16 and are discharged, and the direction indicated by an arrow in figure 2 is the direction towards which the sediments are precipitated. Due to the existence of the sealed end plate 14, the inside of the sludge discharge channel 16 can be regarded as a static water area without water flowing from the water inlet to the water outlet, sediment cannot be washed and stirred, and the sediment sedimentation effect is good.

However, the lateral flow sedimentation device inevitably has flow-through dead corners in the actual construction process, and one condition is that the lateral flow sedimentation device 1 is firstly assembled into a whole in a workshop from the cross section of the pool perpendicular to the water flow direction, namely the flow-through surface, see fig. 3, in order to meet the process installation requirements, the width of the assembled sedimentation device is usually smaller than the transverse dimension of the pool, a smaller gap is reserved, but the gap in the construction is usually larger, namely the distance between the pool wall 18 and the pool wall 19 is larger, when the device is installed in the pool, the sedimentation device is close to the pool wall 18, and a larger gap area, also called flow-through dead corner 2, is formed between the right end of the sedimentation device 1 and the pool wall 19. In another situation, when viewed from the flow cross section, the lateral flow sedimentation devices 1 are connected in parallel, and a flow dead angle 2 is also formed between the lateral flow sedimentation devices and the lateral flow sedimentation devices. In the process that flocculates are precipitated by the lateral flow precipitation device 1, the flocculates enter the dead angle area to be freely precipitated, firstly, the flocculates are influenced by water flow in the overflowing channel when being separated from the lateral flow precipitation device and entering the overflowing dead angle 2, the discharge of the flocculates is influenced by the flow of the water flow, and the flocculates entering the overflowing dead angle 2 can enter the overflowing channel by the inertia of the water flow, so that the alum leakage phenomenon is caused; secondly, flocs are free to settle in the overflowing dead angle 2, the speed is generally 0.3-0.6mm/s, the sludge concentration in the upper area is low, and the sludge concentration in the lower area is high, so that blockage is easily caused, and the effluent quality is influenced.

The above is just one specific implementation form of the existing lateral flow sedimentation device, and the working principle of other existing lateral flow sedimentation devices is basically the same, and only the structure is changed in various ways on the section shown in fig. 2. For example, there is also a lateral flow sedimentation device which is composed of a plurality of parallel inclined plates and a plurality of partition plates arranged between adjacent inclined plates, and the working principle of the lateral flow sedimentation device is substantially the same as that of the lateral flow sedimentation device disclosed in CN102284200A, but the lateral flow sedimentation device has the characteristic of simpler structure.

Therefore, reducing the flow dead angle region is a technical problem to be solved urgently for improving the precipitation efficiency. Chinese patent application publication No. CN11035723A discloses an adapter device, which comprises a frame and a plurality of mud blades, wherein each mud blade comprises a precipitation extension part and a baffle part, an included angle is formed between the precipitation extension part and the baffle when viewed from the cross section of the mud blade, the precipitation extension parts of the plurality of mud blades are fixedly connected through the frame, and the precipitation extension parts of the plurality of mud blades are arranged in parallel.

The adapter device has the disadvantages that the adapter device and the lateral flow sedimentation device need to be in butt joint at multiple positions during field installation, and the adapter device is only suitable for the lateral flow sedimentation device with the specific structural form shown in figure 1.
