Abstract
The utility model relates to an aeration and oxygenation flexible pipe which is made of a flexible pipe with definite elasticity. The flexible pipe can be made of PVC plastics, fibrous reinforcement PVC plastics, rubber, fibrous reinforcement rubber, etc. A pipe wall is evenly provided with a plurality of holes in a straight line shape, and the utility model has the improvement that the diameter of the flexible pipe is used as a boundary, and the length of the hole at the lower half part is greater than the length of the hole at the upper half part. In general, the length of the hole at the upper half part is 5.0-8.0 mm, and the length of the hole at the lower half part is 5.5-8.5 mm. Because the hole at the bottom is enlarged to reduce the opening tensile force, accumulated water is easy to drain. Once the aeration and oxygenation flexible pipe is inflated, the accumulated water in the pipe can be rapidly drained, and the oxygenation efficiency is also improved.
Description
The utility model relates to the device of biochemical treatment sewage.
Aerating apparatus is an equipment very crucial in the biochemical treatment sewage technology, it not only requires higher oxygen-transfer efficiency, easy to maintenance, arranged long running period, be convenient to management etc., also be to the important judgement criteria of aerating apparatus, because they all will influence the final treatment effect and the processing cost of entire sewage device.
The aeration parts are a kind of inflexible perforated pipes in the early stage aerating apparatus, and its shortcoming is that oxygenation capacity is the end of than.In addition, because perforated pipe produces burr unavoidably adding man-hour inwall aperture, the burr place very easily causes microorganism growth so that plug-hole.In case stop aeration, pore is also very easy in sludge blockage.Though the aeration spray head of Tui Chuing is difficult for stopping up thereafter, oxygenation capacity is lower than perforated pipe.The micropore ceramics aerator has higher oxygenation capacity, yet its structure is but too complicated, and needs to use air compressor machine as the oxygenation source of the gas, and air also must be through purifying treatment.The investment of entire equipment is higher, and the micropore ceramics aeration head very easily stops up in addition, must be regularly through roasting or pickling manipulation of regeneration, and running expense is also considerable.
The patent No. is that the utility model of 87211323.X has been released a kind of aeration flexible pipe, and its employing has certain elastic flexible pipe (as plastics tubing, rubber hose) and makes.Open some " cross " holes or circular hole on the tube wall equably, then often be reduced to a vertical masonry joint during practical application.This aerator practical effect simple in structure is splendid, and solarization air cap is by whippy tube wall, and the degree of unlatching changes voluntarily with the pressure reduction inside and outside the tube wall, has reduced the solarization air cap possibility of jamming.And aeration parts and air delivering pipeline unite two into one, and not only reduced the construction investment of device, and the failure rate during operation also greatly reduces.Just applied very soon after this aeration flexible pipe is released, yet found that in application after operation for some time, particularly often be in intermittent operation, the bottom of flexible pipe can ponding.Therefore, the hole seam of flexible pipe bottom normally is used for sluicing and seldom is used for aeration.The hole of existing aeration flexible pipe tube wall is made and is caused size consistent, and generally produces dense and the less bubble of diameter in order to guarantee, and the length of hole seam is all opened to such an extent that lack as much as possible (not exceeding to have excessive windage), so that causes the difficulty that sluices.
The purpose of this utility model provides a kind of improved aeration aerating flexible pipe, it is also made by having the flexible pipe that certain bullet gives birth to, and flexible pipe can be any in PVC plastics, fiber reinforcement PVC plastics, natural rubber, fiber reinforcement natural rubber, synthetic rubber, fiber reinforcement synthetic rubber, urethane, the fiber reinforcement polyurethane flexible pipe.Have to even tube wall some " word " hole seam, its improvements are that the diameter with flexible pipe is the boundary, and the length of Lower Half hole seam is greater than the length of first half hole seam.The length of general first half hole seam is 5.0～8.0mm, and the length of Lower Half hole seam is 5.5～8.5mm.
Accompanying drawing is the schematic appearance of the utility model embodiment.
In the present embodiment, aeration flexible pipe adopts fiber reinforcement PVC plastic hose 1 to make, and is the boundary with the diameter, and the length of the hole seam 2 of the first half is 6.0mm, and the length of the hole seam 3 of Lower Half is 8.0mm, and the spacing of hole seam is all identical.
Because the tension force of opening after the hole of bottom seam strengthens reduces, and is easier to the drainage of ponding. So compared with prior art, after the in a single day inflation of the aeration oxygenator flexible pipe that the utility model provides, The very fast ponding that just can drain in the pipe, oxygen-transfer efficiency also increases.
Claims (2)
1. aeration aerating flexible pipe that is used for biochemical treatment sewage, make by having certain elastic flexible pipe, have to the even tube wall of flexible pipe some " one " font hole seam, it is characterized in that the diameter with flexible pipe is the boundary, the hole seam length of the first half is 5.0～8.0mm, and Lower Half hole seam length is 5.5～8.5mm.
2. according to the described aeration aerating flexible pipe of claim 1, it is characterized in that described certain elastic flexible pipe can be any in PVC plastics, fiber reinforcement PVC plastics, natural rubber, fiber reinforcement natural rubber, synthetic rubber, fiber reinforcement synthetic rubber, urethane, the fiber reinforcement polyurethane flexible pipe.
