Description

A kind of Pneumatic Drain Device
Technical field
The utility model relates to mechanical facilities of irrigation and drainage field, in particular to a kind of Pneumatic Drain Device.
Background technique
Currently, our common blowdown apparatus are usually the submersible sewage pump for being placed in sewage bottom of pond portion, it is widely used in producing In the processing links of sewage, sludge in life, but, volume more for some quantity containing solid waste be larger or fiber etc. The occasion of prehensile waste, the impeller that submersible sewage pump and line clogging or pump are easy to happen in practical application are easy stuck to cause to burn out The failures such as motor, even if taking the increase strainer measure before Pump Suction Nozzle, it is still necessary to often cleaning and replacement strainer.
Compressed air be it is a kind of commonly using power, many occasions that produce have ready-made compressed air pipe.Then, We attempt to design a set of Pneumatic Drain Device, using effect is preferable using compressed air.
Utility model content
The purpose of this utility model is that defect according to prior art, provides a kind of Pneumatic Drain Device, it is described pneumatic The technical solution of blowdown apparatus is achieved in that
A kind of Pneumatic Drain Device, including reduced pipe, conditioning tank, compressed air hose, intake valve, sewage pipe, cleaning water pipe, Gate valve, driving and collecting pit;The reduced pipe be it is horn-like, upper end, which is connected through a screw thread, is fixedly mounted a sewage pipe, different The lower semisection of diameter pipe and sewage pipe is both placed in conditioning tank, and a circular hole is provided on the side surface of reduced pipe, is fixed outside circular hole It is connected to a compressed air hose, the upper semisection of the compressed air hose is fixedly installed with an intake valve by flanged joint, Lower semisection is immersed in conditioning tank, is connected and fixed on the upper semisection of the sewage pipe by axle key and is equipped with a driving, blowdown The upper end of pipe is provided with an opening and is connected to a cleaning water pipe, the right side of the cleaning water pipe, passes through axle key company on sewage pipe It connects and is fixedly installed with a gate valve, another end opening of sewage pipe is placed in collecting pit.
Further, the reducing pipe diameter be 100~150mm, be highly 50~100mm, opening angle be 90 °~ 120°。
Further, the Circularhole diameter on the reduced pipe side wall is 10~20mm.
Further, the diameter of the compressed air hose is 10~20mm.
Further, the internal diameter of the sewage pipe is 100~150mm.
Working principle: after compressed air enters reduced pipe by compressed air hose, gas is spread around, all directions Pressure is equal, and the sewage in reduced pipe is extruded from sewage pipe connected to it and downwards from water sucking mouth upwards.As compression is empty After gas draining acting, the discharge of air-water mixture, reducing overpressure is decreased, when being less than the hydraulic pressure of water sucking mouth bottom, Under the action of water pressure, sewage can run through water sucking mouth supplement and flow into, and form similar siphonage.Meanwhile water flow is from reduced pipe Since section becomes smaller after into sewage pipe, upflow velocity is accelerated.It, can shape in sewage pipe in this way under the promotion of part ascending air At stable ascending current, sewage can be smoothly discharged.
A kind of Pneumatic Drain Device of the utility model, structure is simple, and failure rate is low, for ease of maintenaince protects, contaminant removal effectiveness Height meets application requirement.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the test device of the utility model;
Appended drawing reference: 1- reduced pipe, 2- conditioning tank, 3- compressed air hose, 4- intake valve, 5- sewage pipe, 6- clean water pipe, 7- gate valve, 8- driving, 9- collecting pit.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of Pneumatic Drain Device, including reduced pipe 1, conditioning tank 2, compressed air hose 3, intake valve 4, row Dirty pipe 5, cleaning water pipe 6, gate valve 7, driving 8 and collecting pit 9;The reduced pipe 1 be it is horn-like, upper end is connected through a screw thread fixation A piece sewage pipe 5 is installed, reduced pipe 1 and the lower semisection of sewage pipe 5 are both placed in conditioning tank 2, on the side surface of reduced pipe 1 It is provided with a circular hole, is fixedly connected a compressed air hose 3 outside circular hole, the upper semisection of the compressed air hose 3 passes through flange It is connected and fixed and an intake valve 4 is installed, lower semisection is immersed in conditioning tank 2, passes through axle key on the upper semisection of the sewage pipe 5 It is connected and fixed and a driving 8 is installed, the upper end of sewage pipe 5 is provided with an opening and is connected to a cleaning water pipe 6, the cleaning The right side of water pipe 6 is connected and fixed on sewage pipe 5 by axle key and is equipped with a gate valve 7, and another end opening of sewage pipe 5 is placed In collecting pit 9.
When it is implemented, 1 diameter of reduced pipe is 100~150mm, it is highly 50~100mm, opening angle is 90 ° ~120 °.
It is highly 90mm further when it is implemented, 1 diameter of reduced pipe is 130mm, opening angle is 100 °.
When it is implemented, the Circularhole diameter on 1 side wall of reduced pipe is 10~20mm.
Further when it is implemented, the Circularhole diameter on 1 side wall of reduced pipe is 15mm.
When it is implemented, the diameter of the compressed air hose 3 is 10~20mm.
Further when it is implemented, the diameter of the compressed air hose 3 is 15mm.
When it is implemented, the internal diameter of the sewage pipe 5 is 100~150mm.
Further when it is implemented, the internal diameter of the sewage pipe 5 is 130mm.
Working principle: after compressed air enters reduced pipe 1 by compressed air hose 3, gas is spread around, all directions Pressure it is equal, the sewage in reduced pipe 1 is extruded from water sucking mouth from sewage pipe 5 connected to it and downwards upwards.With pressure After the draining acting of contracting air, the discharge of air-water mixture, pressure is decreased in reduced pipe 1, when the water for being less than water sucking mouth bottom When pressure, under the action of water pressure, sewage can run through water sucking mouth supplement and flow into, and form similar siphonage.Meanwhile water flow is from different Diameter pipe 1 enters after sewage pipe 5 since section becomes smaller, and upflow velocity is accelerated.In this way under the promotion of part ascending air, sewage pipe Stable ascending current can be formed in 5, sewage can be smoothly discharged.
The technology contents and technical characteristic of the utility model have revealed that as above those skilled in the art still may base In the utility model teaching and make the replacement and modification without departing substantially from the utility model in essence, therefore, the utility model protection Range is not limited to the revealed content of embodiment, also includes various replacements and modification without departing substantially from the utility model in essence.
