Description

Adaptation device and water treatment pool

Technical Field

The utility model relates to a water treatment pond and auxiliary device thereof, specifically speaking relates to adapter device and water treatment pond.

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. A settling device is installed in a settling zone, and chinese patent application publication No. CN102284200A discloses a settling device as shown in fig. 1 and 2, wherein fig. 1 is a perspective view of the settling device, and fig. 2 is a cross-sectional view of the settling device perpendicular to a water flow direction.

Referring to fig. 1, the direction indicated by the arrow in fig. 1 is the water flow direction. The 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 above-mentioned sedimentation device inevitably has an overflow dead angle in the actual construction process, and one condition is that from the cross section of the pool perpendicular to the water flow direction, i.e. the overflow surface, see fig. 3, the sedimentation device 1 is firstly assembled into a whole in a workshop, 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 should be reserved, but the gap in the construction is usually larger, i.e. the distance between the pool wall 18 and the pool wall 19 is larger, when the sedimentation device is installed in the pool, the sedimentation device is close to the pool wall 18, and a larger gap area, also called an overflow dead angle 2, is formed between the right end of the sedimentation device 1 and the pool wall 19. The other situation is that the sedimentation devices are connected in parallel when viewed from the overflowing section, and overflowing dead corners 2 are formed between the sedimentation devices. In the process that flocculate is precipitated by the precipitation device 1, the flocculate can enter the dead angle area to be freely precipitated, firstly, the flocculate is influenced by water flow in the overflowing channel when being separated from the precipitation device and entering the overflowing dead angle 2, the discharge of the flocculate can be influenced by the flow of the water flow, and the flocculate 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.

In addition, a sedimentation device comprises a plurality of parallel inclined plates and a plurality of partition plates arranged between the adjacent inclined plates, the working principle of the sedimentation device is different from that of the sedimentation device disclosed in CN102284200A, but the 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.

Each slide mud blade 31 has a precipitation extension part 311 and a baffle part 312, an included angle is formed between the extension precipitation part and the baffle part, and the precipitation extension parts 311 of the plurality of slide mud blades 31 are parallel to each other and are arranged at equal intervals and are fixedly connected through 2 rod pieces 32. The alternative material of construction of the adapter 3 is the same as the precipitation device it is adapted to, and may be metal, plastic, alloy, etc.

Second embodiment of the adapting device

The difference between this example and the previous example is that the extension length of the settling extension 311 of the sludge blade 31 is different, and the extension length from top to bottom gradually increases, and the extension length is the distance from the edge adjacent to the baffle portion 312 to the edge far from the baffle portion 312, that is, the extension length of the uppermost sludge blade 31 in fig. 4 is the shortest, and the extension lengths of the downward sludge blades 31 gradually increase.

Other embodiments of the adapting device

Obviously, the number of the rods 32 between each two of the vanes 31 may also be multiple, and the rods 32 of the whole adapter may also be arranged non-collinear, for example, in such a way that the rods 32 are arranged perpendicular to the sedimentation extension 311. Alternatively, the skeleton may take the form of spacers disposed between two of the vanes 31. In addition, the member that functions to connect two adjacent blades is not limited to the rod member 32, but may be a connecting plate or a connecting column that is fixedly connected to the plurality of baffle portions 312.
