Abstract
The invention discloses an injection pump with an anti-blockage annular nozzle. The injection pump is composed of a suction tube, the annular nozzle, a throat tube, a diffusion tube and an output tube which are sequentially arranged along the same axis, wherein a movable switch jacket which is in slide fit, capably of axially ascending by virtue of an air pressure, and capable of axially descending by virtue of gravity or elasticity after the air pressure is eliminated. The injection pump disclosed by the invention is characterized in that during start-up, while the annular nozzle is enabled to carry out air injection by a pressure airflow, the movable switch jacket is lifted by the pressure airflow through an air channel in a nozzle jacket to open the orifice of the annular nozzle, and synchronous operation is realized by the two components; during shut-down or fault emergency shut-down, the movable switch jacket moves downwards under the action of the own gravity or external force (such as elasticity) to close the orifice of the annular nozzle and prevent the conveyed medium from flowing back and entering the orifice to block the annular nozzle, thus the pump can normally run for a long time.
Description
Technical field
The present invention relates to a kind of Jet injector, a kind of jet pump of ring nozzle.
Background technique
Sewage pump, pollution discharge pump, submerged pump, Non-blinding pump etc. are used for carrying the conveying equipment with the medium of blocky-shaped particle and long fibre material, are widely used in the blowdowns such as municipal engineering, environmental protection pollution treatment, channel cleanout and power plant's deashing, chemical industry, metallurgy, mine.In sewage disposal process, the runner of existing blowdown pump impeller runs into blocky-shaped particle and long fibre material, is easily stopped up and cannot carry out the conveying of medium, has affected the normal operation of pumping equipment, even occurs stuck phenomenon.
According to pollution discharge pump without stop up, the requirement of anti-entangling energy, Jet injector has great potential as Non-blinding pump, Jet injector is divided into two kinds, injection stream centered by one, two is ring nozzle jet, the latter is better than the former without plugging performance, the Jet injector of ring nozzle is made up of suction pipe, ring nozzle, trunnion, extension tube, the output tube of coaxial line, movement-less part in interior, has cost low, easy to maintenance, simple operation and other advantages.
The patent No. 200510041417.3 " a kind of Pneumatic injection pump " and the patent No. 03278315.9 " Pneumatic jet non-blocking sludger " all disclose the jet pump structure with ring nozzle, runner spaciousness, superior without plugging performance, but all there is same shortcoming in two patents, during because of fault emergency shutdown, be transferred medium back flow, enter the ring nozzle that there is no air pressure, even fill whole nozzle chamber, in medium, there is silt, rubble, random grass and various fibre object, start again, pressurized air also cannot be sprayed, the essential disassembly, cleaning of shutdown in time, and this disassembly, cleaning process bothers very much, waste time very much, have a strong impact on the normal use of pump.
Summary of the invention
The object of the invention is to: the shortcoming existing for existing jet pump, propose a kind of in the time shutting down the spout of ring nozzle can be closed in time, avoid the blocked ring nozzle anti-plugging jet pump of ring nozzle.
In order to achieve the above object, the anticlogging jet pump of ring nozzle of the present invention, comprise the suction pipe 1 being arranged in order along same axis, ring nozzle 2, trunnion 3, diffusing tube 4, output tube 5, described ring nozzle 2 is made up of as the cone core of nozzle and with the nozzle overcoat 6 of taper hole suction pipe 1, nozzle overcoat 6 is packed on the sheath 7 that lower end has radial direction through hole, the outside of this sheath 7 is fixed with high-pressure chamber 8, in this high-pressure chamber 8, suction tude 9 is housed, its special way is: sliding joining is equipped with in the outside of described trunnion 3, the moving switch cover 10 that utilizes air pressure axially to rise and rely on gravity or spring energy axially to move down after air pressure is eliminated, on described nozzle overcoat 6, be shaped with the compressed-air actuated air flue 11 promoting for moving switch cover 10.
The jet pump of said structure is in the time of start, and forced draft, by air flue 11 lifting mobile switch sleeves 10, carries out ring nozzle 2 jet, and the lifting of moving switch cover 10 and ring nozzle 2 carry out jet, have accomplished synchronous operation.When shutdown or when fault emergency shutdown, moving switch cover 10, under the Action of Gravity Field of self or under external force (as elastic force) effect, moves down the spout of closing ring nozzle 2, prevents that the medium back flow being transferred from stopping up ring nozzle 2.
Good effect of the present invention is: utilize moving switch cover 10 and pressurized air synchronous operation, avoided the obstruction of ring nozzle 2, reduced shutdown man-hour and maintenance man-hours, guaranteed the long-term normal operation of pump.

Embodiment
Fig. 1 is the basic block diagram of existing jet pump.It is made up of the suction pipe 1 being arranged in order along same axis, ring nozzle 2, trunnion 3, diffusing tube 4, output tube 5, and described ring nozzle 2 is made up of as the cone core of nozzle and with the nozzle overcoat 6 of taper hole suction pipe 1.The jet pump of this structure, in the time of disorderly closedown, is transferred medium back flow and enters in ring nozzle 2, and pump is shut down cannot work on, and delays the operation man-hour of pump.
Fig. 2 is the structural drawing of ring nozzle anti-plugging jet pump.Install a moving switch cover 10 in the outside of trunnion 3 additional, on nozzle overcoat 6, be shaped with the compressed-air actuated air flue 11 promoting for moving switch cover 10.
Fig. 3 is the structural drawing of moving switch cover 10.
Fig. 4 is the structural drawing in the time of jet pump start operation.When start, forced draft sprays from ring nozzle 2, and meanwhile, forced draft, through the synchronous lifting moving switch cover 10 of air flue 11, is opened ring nozzle 2, carries out fed sheet of a media.
Fig. 5 is in the time of disorderly closedown; phase diagram when moving switch cover 10 is closed ring nozzle 2; in the time of fault emergency shutdown; moving switch cover 10 is under Action of Gravity Field own or under elastic force effect; decline and arrive at the upper-end surface of suction pipe 1; closed ring nozzle 2, seals spout, stops the medium refluxing to enter ring nozzle 2.
The present invention is the anticlogging jet pump of ring nozzle, owing to having anticlogging advantage, can be used as sand suction pump, sludge pump, removing sludge, ore deposit tail pump, fruit pump, except for delivery of wet feed, also can carry siccative, as dry sand, cement, paddy etc.
The present invention also can adopt press water to be used as power, and becomes liquid stream and sprays Non-blinding pump.
