Description
Technical Field
The invention relates to the technical field of liquid, in particular to an intelligent sand measuring mobile gas stripping pump and a using method thereof.
Background
During the liquid transportation process, it is often necessary to clean out the sediments and dirt under the liquid. The traditional method is to use electric pumps (dirt pump, submersible dirt pump, screw pump, etc.) for conveying, but the dirt cannot be lifted because the dirt often entangles the impeller; there is therefore a need for a bladeless lifting device.
Although a common air lift pump can lift dirt in an air lift mode, the common air lift pump is sometimes blocked and cannot be used, and the air lift pump needs to be manually disassembled for cleaning, so that time and labor are wasted.
Because the dirt pump and the common air lift pump cannot measure whether sediments and dirt needing to be lifted exist under the liquid or not, the air lift device can only be started continuously or at regular time, so that a large amount of electric energy is wasted, a large amount of water resources are wasted, and the direction of carbon emission and carbon neutralization advocated by the state is not met.
An aeration grit chamber is the most common sand removing facility in urban sewage treatment plants in China, sand suction equipment is generally arranged on a bridge type truss car, and the biggest problem is that the sand suction is not thorough. The reason for this is that sand is difficult to settle at the water inlet end and is deposited in a large amount at the water outlet end, and the sand suction device of the aeration grit chamber is fixed to move back and forth at the water inlet and outlet ends to suck sand, so that too much sand residue may cause damage to the sand suction device, and too little sand particle cannot achieve the sand suction effect. Therefore, in actual operation, more sand grains are accumulated at the water outlet end of the aeration grit chamber, especially sand slag is increased instantly when rain and snow fall, sand suction equipment is buried, the sand suction equipment cannot be stopped, and finally, only the chamber can be emptied and sand is manually cleaned. Therefore, during operation, the sand suction equipment is required to continuously adjust the sand suction height and the machine shutdown time according to the sand slag accumulation degree of the sand collection tank, so that the required sand suction effect is achieved while the equipment is protected.
In the second embodiment, a large amount of water is used for mixing asphalt, mud and slag in the existing stage of the petroleum sedimentation tank, and the mixture is pumped out by a sewage pump and then sent to a sewage plant for treatment; thus, the sewage pump needs fluidity, so that a large amount of water is needed to dilute the sewage for pumping, and a large amount of energy and capital are consumed; therefore, a device which can extract high-concentration dirt asphalt and can lift a small amount of water is needed. The efficiency is improved, the energy is saved, the emission is reduced, and the carbon emission is reduced.
Therefore, the prior art needs to be improved, and the intelligent sand-measuring mobile air stripping pump with a novel structure is invented to solve the problems.

An intelligent device of an air lift pump as claimed in claim 1, 2 and 3, which comprises a sand measuring power device, a sand measuring power support, a sand measuring sensor, a sand measuring probe and a sand measuring protection tube, wherein the sand measuring function is realized by detecting signals of the sensor through a lifting probe, analyzing and comparing whether the dirt around the liquid lift pipe is about to block the lift pipe or not, and then starting the air lift pump to lift the dirt; when the analysis contrasts that no dirt exists on the periphery of the lift pipe, the air lift pump is stopped; therefore, the start and stop of the gas stripping pump can be intelligently controlled, the energy is saved, and the carbon emission is reduced; and fundamentally solved and can't judge that the filth will bury the phenomenon that the air lift pump can't promote the filth on the air lift pump lift fluid pipe.
5. The intelligent device of an air lift pump as claimed in claims 1, 2, 3 and 4, further comprising a liquid tube power device, a liquid tube power support and a liquid tube sensor, wherein the liquid tube sensor is formed into a liquid tube lifting automatic lifting device; the main function is to lift the air stripping pump according to the signal of the sand detecting sensor; the second function can also automatically lift the air lift pump according to the quantity of sand slag dirt sensed by the liquid pipe sensor, so that the content of the lifted dirt is uniform, the efficiency of the air lift pump is improved, the blockage is avoided, and the application range of the air lift pump is expanded. The third function is that when the lifting liquid pipe is blocked and the double-hole back flushing pipe cannot be flushed, the air lift pump is lifted and then back flushed to clean dirt, and the air lift pump can be normally used in the lifting and lowering processes; this is not possible with conventional gas-lift pumps.
6. The fluid tank as defined in claim 1, wherein the fluid tank is a sewage tank (intake well, sewage channel, coarse grid channel, fine grid channel, primary sedimentation tank, secondary sedimentation tank, aeration tank, sand sedimentation tank, reaction tank, rhodobacter tank, sewage well, sewer, septic tank), construction site puddle, river channel, deep well, seawater, petroleum sedimentation tank, etc.
7. The blower of claim 1, which is primarily for powering a gas lift pump; the air hose is connected with the air pump pipe, so that the condition that the air pump can be lifted is achieved; the fan is controlled by the frequency converter, the fan normally runs at about 40Hz, the sand slag abnormally increases, the sand slag runs at 50Hz, and the sand slag blocks the backflushing, and the sand slag is run at 60Hz, so that the energy is saved. And the liquid dirt can be lifted out according to the adjustment of the adjusting frequency converter.
8. The autonomous system of claim 1 wherein the primary function is to analyze the contamination of the fluid reservoir provided by the sand measuring device by means of a PLC. When the measured dirt reaches the mouth of the lifting liquid pipe, a control air lift pump, a fan, a valve and the like are started to lift the dirt according to the discontinuous measured dirt of the sand measuring device in normal conditions; when it is measured that the sewage has reached the bottom of the tank, the lifting of the sewage is stopped. Thereby achieving the purpose of energy conservation and reducing carbon emission.
9. The automatic control system according to claim 1, wherein the second main function is to analyze data provided by the liquid tube sensor through the PLC, if an abnormal condition occurs, when the measured dirt is buried in the liquid lifting tube opening, the liquid tube is lifted to expose the liquid lifting tube, and then the control air lift pump, the fan, the valve and the like are turned on to lift the dirt; when measuring the filth and reducing, control liquid pipe device and follow the reduction, the air lift pump is normally opened to the interim, promotes the filth, when measuring the filth and having reached the bottom of the pool, just stops to promote the filth.
