The purpose of this utility model is achieved in that a kind of gas distributor, it comprises gas spray pipe, described gas spray pipe front end is provided with nozzle, described gas spray pipe rear end is provided with gas spray pipe Connection Block, described gas spray pipe Connection Block rear end is connected with pneumatic flowrate automatic control and self closing device, described pneumatic flowrate automatic control and self closing device comprise outer cover, rubber diaphragm, the first spring base and spring, adjusting bolt, needle-valve connecting rod, the second spring base and needle-valve, described outer cover is fixedly connected with gas spray pipe Connection Block, described rubber diaphragm is fixedly installed between outer cover and gas spray pipe Connection Block, described the first spring base is fixedly installed on rubber diaphragm center, described spring and the second spring base are arranged in outer cover, described spring is arranged between the first spring base and the second spring base, described adjusting bolt is arranged at outer cover rear end, described adjusting bolt front end and the second spring base offset, described needle-valve connecting rod is horizontally placed on gas spray pipe and gas spray pipe Connection Block center, described needle-valve rod rear end is fixedly connected with the first spring base, described needle-valve connecting rod front end is fixedly installed needle-valve, described needle-valve and nozzle cooperatively interact.
Described nozzle arranged outside has nozzle protector.
Described needle-valve comprises needle seating and Rubber end, and described needle seating is fixedly connected with needle-valve connecting rod front end, and described Rubber end is arranged on needle seating.
Described nozzle adopts wear-resistant ceramic to make.
Compared with prior art, the utlity model has following beneficial effect:
A kind of gas distributor of the utility model, its inflation and gas dispersion unit are tubular structure, the wear-resistant ceramic nozzle of gas spray pipe front end can, according to the requirement of aeration quantity, be changed the nozzle of different size; Pneumatic flowrate automatic control and the self closing device of gas spray pipe rear end, can guarantee that flotation column, in the unexpected step-down of air supply system or completely decompression in the situation that, automatically cuts out this gas distributor, thereby prevent entering of ore pulp.Because the utility model is the single hole aerator that a kind of external is installed, therefore in alkaline ore pulp, can there is not spray nozzle encrustation, just in case there is spray nozzle encrustation, this gas distributor can be pulled down from flotation column easily, keeps in repair.

Detailed description of the invention
Referring to Fig. 1, Fig. 2, a kind of gas distributor of the utility model, it comprises gas spray pipe 1, described gas spray pipe 1 front end is provided with nozzle protector 4, in described nozzle protector 4, be provided with nozzle 5, described nozzle 5 adopts wear-resistant ceramic to make, described gas spray pipe 1 rear end is provided with gas spray pipe Connection Block 3, described gas spray pipe Connection Block 3 rear ends are connected with pneumatic flowrate automatic control and self closing device 2, described pneumatic flowrate automatic control and self closing device 2 comprise outer cover 2.1, rubber diaphragm 2.2, the first spring base 2.3 and spring 2.4, adjusting bolt 2.5, needle-valve connecting rod 2.6, the second spring base 2.7 and needle-valve 2.8, described outer cover 2.1 is fixedly connected with gas spray pipe Connection Block 3 by bolt, described rubber diaphragm 2.2 is fixedly installed between described outer cover 2.1 and gas spray pipe Connection Block 3, described the first spring base 2.3 is fixedly installed on rubber diaphragm 2.2 centers, described spring 2.4 and the second spring base 2.7 are arranged in outer cover 2.2, described spring 2.4 is arranged between the first spring base 2.3 and the second spring base 2.7, described adjusting bolt 2.5 is arranged at outer cover 2.2 rear ends, described adjusting bolt 2.5 front ends and the second spring base 2.7 offset, described needle-valve connecting rod 2.6 is horizontally placed on gas spray pipe 1 and gas spray pipe Connection Block 3 centers, described needle-valve connecting rod 2.6 rear ends are connected with the first spring base 2.3 by nut, described needle-valve connecting rod 2.6 front ends are provided with needle-valve 2.8, described needle-valve 2.8 comprises needle seating 2.8.1 and Rubber end 2.8.2, described needle seating 2.8.1 is fixedly connected with needle-valve connecting rod 2.6 front ends, described Rubber end 2.8.2 is arranged on needle seating 2.8.1, described needle-valve 2.8 cooperatively interacts with nozzle 5, on described gas spray pipe Connection Block 3, be provided with compressed air inlet 6, described nozzle protector 4 front ends are provided with compressed air outlet 7.
Operation principle:
In the time there is no air pressure in system, before dispatching from the factory, set cracking pressure, by adjusting bolt, spring is applied to load in advance, depress rubber diaphragm and make needle-valve compress nozzle, prevent that mortar from refluxing;
In the time that air pressure exceedes cracking pressure, rubber diaphragm is retracted slightly, makes needle-valve change position, and air starts to flow simultaneously.
In the time that air pressure is increased to routine operating pressure, rubber diaphragm is retracted completely, and air reaches at full speed.
