Abstract
At present, a mud scraping and sucking machine needs to be used in the secondary sedimentation tank stage of domestic sewage treatment, a siphoning type mud sucking device is used in some sewage treatment technologies and is mainly a segment of inverted U-shaped pipe, natural flowing of muddy water is achieved through the natural pressure difference generated by the water level difference of the two sides of a pipeline, the function can be achieved by emptying original air in the pipeline, an existing used method is achieved mainly by additionally arranging a vacuum pump, the vacuum pump needs to be adjusted multiple times before running, adjusting needs to be conducted multiple times again when the water level difference changes, and time and labor are consumed. Therefore, the invention provides a jet-type siphoning machine. According to the jet-type siphoning machine, exhausting is conducted through the jet principle, after air is exhausted, a check valve in the jet-type siphoning machine is automatically switched off, a pressure sensor arranged on the check valve controls a motor to automatically stop running, and manual machine type adjusting is not needed. The jet-type siphoning machine is simple in structure, easy and convenient to operate, easy to install and low in cost.
Description
Technical field
The present invention relates to a kind of Novel siphon type suction dredge of employing jet venting principleand.
Background technology
At present, the second pond stage of domestic sewage disposal is required for using scraping and sucking machine, and in some of which sewage treatment process, use hydrocone type mud-sucking device, the device is mainly one section of inverted U-tube, the natural pressure reduction produced using the water-head on pipeline both sides is realizing the natural flowing of muddy water, and the function needs original air emptying in pipeline to realize, the method used at present is mainly additional vacuum pump, the method is repeatedly debugged before needing operation, and need repeatedly to be debugged when water-head changes again, waste time and energy.For this, the applicant proposes a kind of new siphon mud pipe, the device is exhausted using jet current principle, and after gas emptying, internal check-valves are automatically switched off, pressure transducer controlled motor on check-valves is automatically stopped operation, artificial type is not needed to debug, simple structure is easy to operate, it is easily installed, cost is relatively low.
The content of the invention
The device is mainly made up of eight parts, i.e. motor（1）；Two-container cylinder（2）；Connection flexible pipe（3）；Jet nozzle（4）；Check-valves（5）；Holddown spring（6）；Pressure transducer（7）；Filter screen（8）With U-tube road（9）.As shown in figure 1, motor（1）With two-container cylinder（2）Connection, two-container cylinder（2）The compressed air of generation is by connecting flexible pipe（3）Into jet nozzle（4）, jet nozzle（4）Middle part is provided with a suction inlet, check-valves（5）Base is connected with clack box, and there is holddown spring valve ball upper end（6）, valve base surface is equipped with pressure transducer（7）, filter screen（8）It is downwardly projected for hemispherical, material is copper, and valve ball material is fluorubber, and valve seat material is rustless steel, and clack box is casting pig, and jet nozzle material is spheroidal graphite cast-iron.

Specific embodiment
Operation principle is：Before siphon is produced, it is full of air, air pressure is atmospheric pressure, check-valves are closed in the case where self gravitation and pressing force of the spring are acted in U-tube the road in.Motor（1）Open drive cylinder（2）Motion produces compressed air, by flexible pipe（3）Into jet nozzle（4）Produce jet, jet nozzle（4）Middle part reduced pressure, suction inlet is inside and outside to produce pressure differential, and air is inhaled into jet nozzle（4）After discharge, now check-valves（5）As pressure differential effect is opened, in U-tube road, air passes through check-valves（5）Into jet nozzle（4）After discharge, until draining net, i.e., check-valves lower end does not have air, and valve ball is closed in the presence of holddown spring and self gravitation, and after the pressure transducer on valve seat detects enough pressure, signal feeds back to motor, and motor shuts down, whole equipment normal operation.
