Description

Advection type sedimentation tank convenient for cleaning sediment

Technical Field

The utility model relates to a sedimentation tank technical field, specifically speaking relates to a advection formula sedimentation tank convenient to clearance sediment.

Background

The advection type sedimentation tank consists of a water inlet, a water outlet, a water flow part and a sludge hopper. The plane of the pool body is rectangular, the inlet and the outlet are respectively arranged at two ends of the pool, the inlet is generally submerged into the water inlet, water flows into the pool body from the water inlet channel through the water inlet holes which are uniformly distributed, and the baffle is arranged behind the water inlet holes, so that the water flow is uniformly distributed on the cross section of the whole pool width; the outlet is provided with an overflow weir to ensure that settled clarified water can flow into the water outlet channel uniformly along the width of the pool. A scum groove and a baffle are arranged in front of the weir to intercept scum on the water surface. The water flow part is the main body of the pool, the width and the depth of the pool ensure that the water flow is distributed uniformly along the water passing section of the pool and slowly and stably flows through the pool according to the designed flow rate. Because the water flow speed is slow, silt and the like carried in water are gradually precipitated under the action of gravity. Sediments such as silt are generally accumulated in the front half part of the tank body. The general design at present:

the first half part of the tank is provided with a sludge hopper for accumulating precipitated sludge, the sludge hopper is arranged below the tank bottom at the front part of the tank, and the hopper bottom is provided with a sludge discharge pipe for discharging sludge regularly. This type generally requires a large depth in the front of the tank to meet the burying requirements of the bucket-type sludge bucket, and requires a slurry pump for pumping the sediment in the sludge bucket, which is costly.

In the first half part of the tank, a sludge hopper is not arranged, and the sludge enters the tank to be cleaned manually at regular intervals. Because the field is small, the operation of personnel is inconvenient, and especially the operation of the sedimentation tank needs to be stopped when slag is removed.

SUMMERY OF THE UTILITY MODEL

The present invention provides a advection type sedimentation tank convenient for cleaning sediment, which can overcome some or some defects of the prior art.

According to the utility model discloses a advection type sedimentation tank convenient to clearance sediment, it is equipped with a plurality of split type sludge hoppers including sedimentation cell body in the sedimentation cell body, is equipped with the mud chamber in the sludge hopper, is equipped with the check valve at the bottom of the mud chamber, and sludge hopper top surface symmetry is equipped with carries the barre.

The setting of a plurality of split type sludge buckets in the sedimentation tank body for sludge bucket can conveniently mention from the pond in, can continue to put into the pond after empting the sediment in the fill, and this kind of clearance sediment mode, personnel need not enter into the pond in, and sedimentation tank also need not the bring to rest, and the pulling of sludge bucket can be realized through carrying the barre. The one-way valve is arranged so that: when the sludge bucket is lowered downwards, the mud-water mixture in the tank enters the bucket, so that the buoyancy of the sludge bucket is reduced, and the sludge bucket is easier to sink to the bottom of the tank; when the sludge bucket is lifted upwards, the mud-water mixture in the tank does not leak out, and the silt in the sludge bucket is ensured to be taken out of the tank smoothly, so that the sludge bucket is very convenient. The utility model discloses simple structure, it is with low costs, efficiency is higher.

Preferably, the handle bar is provided with a block.

The utility model discloses in, the setting up of fixture block makes things convenient for carrying of carrying the barre to carry.

Preferably, a sewage inlet and a drainage ditch are respectively arranged on two sides of the sedimentation tank body.

The utility model discloses in, the setting up of sewage import and escape canal makes things convenient for intaking in the sedimentation tank and drainage.

Preferably, a plurality of baffles are arranged in the sedimentation tank body.

The utility model discloses in, the setting of baffle has the effect that keeps off the flow, can reduce the velocity of flow of sewage, has improved the efficiency of sediment greatly.

Preferably, the baffle is provided with an overflow outlet.

The utility model discloses in, the setting up of overflow mouth makes things convenient for sewage to arrive another region from a region.

Detailed Description

For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings and examples. It is to be understood that the examples are illustrative of the invention only and are not limiting.

Example 1

As shown in fig. 1-4, the embodiment provides a horizontal sedimentation tank convenient for cleaning sediments, which includes a sedimentation tank body 110, a plurality of split sludge hoppers 120 are disposed in the sedimentation tank body 110, a sludge chamber 121 is disposed in the sludge hopper 120, a check valve 130 is disposed at the bottom of the sludge chamber 121, and handle bars 140 are symmetrically disposed on the top surfaces of the sludge hoppers 120.

The setting of a plurality of split type sludge buckets 120 in the sedimentation tank body 110 for sludge bucket 120 can conveniently mention from the pond in, can continue to put into the pond after empting the sediment in the fill, and this kind of clearance sediment mode, personnel need not enter into the pond in, and the sedimentation tank need not the bring to rest yet, and lifting of sludge bucket 120 can be realized through carrying handle pole 140. The one-way valve 130 is arranged such that: when the sludge bucket is lowered downwards, the mud-water mixture in the tank enters the bucket, so that the buoyancy of the sludge bucket is reduced, and the sludge bucket is easier to sink to the bottom of the tank. When the sludge bucket is lifted upwards, the mud-water mixture in the tank does not leak out, and the silt in the sludge bucket is ensured to be taken out of the tank smoothly, so that the sludge bucket is very convenient.
