Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
As shown in Figure 1, the sewage pump that the utility model embodiment provides comprises the pump housing 1, suction tude 2, outlet pipe 3 and curved shape syphon tube 8, wherein,
The described pump housing 1 sealing arranges, and it is provided with water intake, and this water intake is arranged on the bottom of the pump housing, and this water intake is provided with the safety check 4 that can prevent that liquid from refluxing; The top of the described pump housing 1 is provided with water outlet, and along the short transverse of the described pump housing 1, the described water outlet of an end hermetically passing of described outlet pipe 3 stretches in the inner chamber of the described pump housing 1, and the other end then extends towards the outside of the described pump housing 1; One end of described suction tude 2 then extend in the inner chamber of the described pump housing 1, and the other end interconnects with the air feeder in the external world, and described suction tude 2 can be arranged on the top of the described pump housing 1, also can be arranged on the sidewall of the described pump housing 1; Described curved shape syphon tube 8 is arranged in the described pump housing 1 inner chamber, be communicated with straight tube on one side arm of described curved shape syphon tube 8 and communicate with described outlet pipe 3, described suction tude 2 is incorporated into pressurized gas in the described pump housing 1 to communicate with described outlet pipe 3 or seals, be when having liquid in the described curved shape syphon tube 8, described pressurized gas can not enter into this pipe, when not having liquid in the described curved shape syphon tube 8, described pressurized gas is discharged to the pump housing 1 outside by this pipe.
In addition, the end that described outlet pipe 3 stretches into the described pump housing 1 inner chamber extends to the diapire position of the described pump housing 1, the air outlet of described suction tude 2 is not exclusively relative with siphonal another wall port of described curved shape 8a, exert an influence to avoid pressurized gas in the suction tude 2 that liquid is flowed into crooked syphon tube, like this, as shown in Figure 1, when water level subcritical line b, outlet pipe still is immersed in the water, realizes the intermittent fast lifting of liquid.
Preferably, described curved shape syphon tube is U-shaped pipe or V-arrangement pipe or semicircular pipe.
Among Fig. 1, described curved shape syphon tube adopts the form of U-shaped pipe.The working procedure of this sewage pump is described below with reference to Fig. 1:
At first, this sewage pump is immersed in the sewage pond or tank body that need to promote, sewage will flow into the described pump housing 1 and will be full of the whole pump housing from safety check 4, be full of water in the U-shaped pipe, and the maximum static pressure power in pond is P2, and it depends on the height of water in the pond; Subsequently, introduce pressurized air from suction tude 2, its pressure is P1; At this moment, pump housing pressure inside P1 is greater than the hydrostatic pressure P2 in pond, and safety check 4 cuts out automatically; The compressed air driven turnover water pipe 3 of water in the pump housing 1 also rises to outside the discharge;
Water in the pump housing 1 constantly is discharged from, and the water level in the pump housing 1 begins constantly to descend.When water level subcritical line b, namely being lower than curved shape syphon tube 8(is the U-shaped pipe) the position time, the pressurized air in the pump housing 1 enters in the outlet pipe 3 by curved shape syphon tube 8 and discharges.At this moment, the pressure in the pump housing is P3, because P3 will be less than hydrostatic pressure P2, then safety check 4 will be opened automatically, water in the pond flow in the pump housing 1 fast, and the water level in the pump housing 1 is higher than critical line a, when namely flooding curved shape syphon tube 8, water in the pump housing will flow in the curved shape syphon tube 8, at this moment, the pressure in the pump housing returns to P1, and safety check 4 cuts out automatically, water in the pump housing is driven in the outlet pipe 3 under compressed-air actuated effect again, rises to outside the discharge.
Said process constantly circulates repeatedly, thereby under the condition of continuous air feed, outlet pipe 3 constantly has water to discharge, and becomes the sewage pump of a discontinuity draining, thereby realizes the lifting of liquid by this sewage pump simple in structure.
Certainly, described curved shape syphon tube 8 adopts the working procedure of V-arrangement pipe or semicircular pipe identical with the working procedure that adopts the U-shaped pipe, no longer elaborates at this.
In the sewage pump of the present utility model, for convenient transportation and do not take more parking space, thereby described outlet pipe 2 can be connected by screw thread or flange with described water outlet and reaches the purpose that detachability is installed.
Certainly, as other selectable modes, described outlet pipe 2 also can be sealedly connected on the described water outlet by the Plastic Welding mode permanent fixation.
In actual applications, the top of the described pump housing 1 has opening, but, in order to guarantee the sealing of the pump housing 1, then the opening top cover labyrinth of the pump housing 1 has closed lid 5, for example, lid 5 can be arranged on the opening of the pump housing 1 by the mode of welding or by seal ring removably sealing cover be combined on the pump housing 1 correspondingly, it is porose to be shaped on the lid 5, the described hole of outlet pipe 3 hermetically passings.
In addition, described lid 5 is provided with access opening, can check or overhauls the situation of the pump housing 1 inside.
Certainly, as mentioned above, described suction tude 2 can be from hermetically passing on the lid 5 of the pump housing 1, also can be from hermetically passing on the sidewall of the pump housing 1, to be connected with outside air feeder.
The water sucking mouth 31 of described outlet pipe 3 can be normal orifice configuration, promotes liquid more glibly in order to make described outlet pipe 3, preferred version as shown in Figure 1, the water sucking mouth 31 that described outlet pipe 3 stretches into an end of the pump housing 1 inner chamber is the horn-like mouth of pipe.
For easily manufactured, the described pump housing 1 is generally drum, its internal diameter is at least 100 millimeters, height should be at least 100 millimeters, it will be appreciated that, the concrete size of the pump housing 1 can be selected according to actual water lift job requirements, to its size, comprises circumferential size and height dimension detailed row no longer one by one at this.
Certainly, the sectional shape perpendicular to its length direction of the described pump housing 1 also can for example can be quadrilateral or pentagon or Hexagon etc. for other shapes such as square or its regular polygons.
Because chemical industry waste water usually has stronger corrosivity, therefore, preferably, the described pump housing 1, outlet pipe 3, suction tude 2 and curved shape syphon tube 8 are CPVC pipe, UPVC pipe and/or Glass Steel Tube.
The internal diameter of described outlet pipe 3 is at least 20 millimeters, and the internal diameter of described suction tude 2 is at least 15 millimeters.
In addition, the air feeder that is used for the utility model sewage pump is the air compressor of adjustable air flow etc., but in the sewage disposal system of reality, in order to save electric energy, and minimizing space, the too much place of hold facility, described air feeder can link to each other with the aeration tube of sewage disposal system, and namely suction tude 2 directly is connected with the aeration tube of water treatment system, introduces the used air of the on-the-spot aeration of sewage treatment as promoting the gas that liquid is used.
Obviously, above-described embodiment only is for example clearly is described, is not the restriction to mode of execution.Concerning those of ordinary skill in the field, also can make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And the apparent variation of being extended out thus or change still are among the protection domain of the utility model creation.
