Abstract
A kind of prefabricated pumping plant automatic air interchanger, it is admission pipe, ventilation blower fan, blower fan coupling are fastening is successively connected, and is contained in prefabricated pumping plant tank body top with ventilation tracheae to bucket.Ventilation blower fan is controlled automatically by control system, and the air of prefabricated pumping plant inside is taken a breath blower fan when discharging from ventilation tracheae, and the fresh air of outside enters supplementary from ventilation inlet pipe, completes automatic air-exchanging.
Description
Technical field
The utility model relates to municipal administration, new rural village effluent discharge field, particularly relates to prefabricated pumping plant automatic air interchanger.
Background technology
Urbanization process, new countryside construction are fast-developing, more and more higher to the requirement of environmental protection.In city and new rural village, some region limits by condition, and sewage network is perfect not, sewage need be collected the equipment such as rear pumping plant and carry out remote, centralized discharge.Prefabricated pumping plant makes tank body in advance, then in tank body, installs the matching components such as water pump, forms a whole set of off-the-shelf hardware and be arranged in underground sewage pipe network system.Because of it, can to carry out finished productization in factory prefabricated, convenient transportation, installs the advantages such as simple, projected life is long, becomes considerable equipment in town sewage exhaust system.
As shown in Figure 1, prefabricated pumping plant is primarily of top cover 102, ladle body 103, base 108 3 part composition tank body.Sewage is from water inlet pipe mouth 113 from flowing into tank body, and retained by solids through pollution cutting device 112, pollution cutting device can be cleared up after guide rail 111 is put on.Sewage flows to tank base, and pressure liquid level sensor 115 sends signal control water pump 107 and works, and single pump operation during low water stage, during high water, double pump runs.Sewage after water pump suction pressurization, along force pipe 106, is gone out through effluent pipe mouth 104 dispatch, and flap valve 105 prevents from occurring backflow in effluent discharge process.When prefabricated pumping plant internal unit need overhaul, enter into operating platform 114 from access hole 109 along cat ladder 110.Air in pumping plant is kept communicating by ventilating pipe 101 and air.
Existing prefabricated pumping plant does not have ventilatory, in long running, can gather the pernicious gas such as carbon dioxide, methane in pumping plant.When personnel need to enter overhaul in pumping plant time, must interim ventilation equipment carry out air blast incessantly take a breath.This operating conditions there will be following problem:
1. temporarily increase ventilation equipment, on-the-spot need temporarily overlaps supply line in addition, except use inconvenience, also increase Electrical Safety hidden danger;
2. in pumping plant pernicious gas exceed standard and negligence of management time, will produce dangerous to enter the station maintainer's safety and surrounding enviroment;
3. in the pernicious gas assembled in pumping plant, some has corrosive, and to accelerate getting rusty of internal unit aging in discharge not in time, shortens the application life of product.
Summary of the invention
The utility model solves the technical scheme that its technical problem adopts: at arbitrary ventilating pipe place of prefabricated pumping plant, set up an automatic air interchanger, make inner air can carry out recycling replacing with outside air.

Fig. 1 is prefabricated pump station structure schematic diagram.
Fig. 2 is the utility model prefabricated pumping plant automatic air interchanger figure.
Fig. 3 is the A-A amplification view of Fig. 2.
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent; In order to better the present embodiment is described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.Position relationship is described only for exemplary illustration in accompanying drawing; the restriction to this patent can not be interpreted as; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
Detailed description of the invention
As shown in Figure 2, admission pipe 205, ventilation blower fan 204, blower fan coupling 203 are fastening to be successively connected, and is contained in prefabricated pumping plant tank body top with ventilation tracheae 202 pairs of buckets.The number of starts in ventilation blower fan 204 unit interval and single run duration and are automatically controlled by control system.The air of prefabricated pumping plant inside is taken a breath blower fan 204 when discharging from ventilation tracheae 202, and outside fresh air enters supplementary from ventilation inlet pipe 201, completes automatic air-exchanging.Arrow a is depicted as airintake direction, and arrow b is depicted as discharge directions.
As shown in Figure 3, blower fan of taking a breath is made up of flange 301, pipe shell 302, fan blade 303, motor 304, junction box 305, electric wire gland 306, fastening bolt 307, installing plate 308.Described pipe shell 302 two ends are welded with flange 301, and installing plate 308 is welded on pipe shell 302 inwall action position.Described motor 304 is fixed on above installing plate 308 by fastener bolt 307, and power line to be drawn through electric wire gland 306 by junction box 305 and is connected with electrical control cubicles, motor output shaft is installed fan blade 303.
beneficial effect
After adopting the utility model, the pernicious gas assembled in prefabricated pumping plant can be discharged in time automatically, the safety of support personnel and equipment surrounding enviroment, and structure is simple, and stable and reliable for performance, cost can not increase how many again.
