Description

Mine spray dust prevention wind power boosting device

Technical field

The utility model relates to the dustproof field of a kind of mine.

Background technology

The storage cistern operated by rotary motion of mine spray dust prevention water on the ground, utilize potential difference to carry out the static pressure water filling by pipeline, but owing to reason such as depositing dust place, down-hole absolute altitude differs greatly, the dispersion of depositing dust point, distance and supply channel are unreasonable, cause part water place pressure of supply water deficiency, have a strong impact on dust-laying effect, only relying on reasonably, the design pipe-line system can not tackle the problem at its root, even can meet the demands early stage, along with mine is constantly opened up, the problem of hydraulic pressure deficiency also can appear.

The utility model content

The purpose of this utility model is to provide a kind of mine spray dust prevention wind power boosting device.It can utilize the compressed air in the mine airduct that the hydraulic pressure in the atomizing de-dusting pipe network is carried out supercharging, has guaranteed the atomizing de-dusting effect.

The technical scheme that the utility model adopts for achieving the above object is: mine spray dust prevention wind power boosting device, comprise main water box and secondary water tank, the top of main water box is connected with main water inlet tube and main blast pipe, and roof is provided with main relief valve, and the bottom is connected with primary flow pipe; The top of secondary water tank is connected with secondary water inlet pipe and secondary blast pipe, and roof is provided with secondary relief valve, and the bottom is connected with the auxiliary waterexit pipe; Inside wall upper/lower terminal at main water box is provided with level sensor, and major and minor water inlet pipe and major and minor outlet pipe are provided with one way valve, and major and minor blast pipe is provided with valve.

Valve on the above-mentioned major and minor blast pipe is subjected to the upper and lower liquid level sensor gauge tap in the main water box, and locking mutually; Main relief valve and secondary relief valve are subjected to the gauge tap of liquid level sensor up and down in the main water box, and locking mutually.

The beneficial effects of the utility model are: when the hydraulic pressure in the depositing dust pipe network is not enough, utilize the deficiency of the blast compensation hydraulic pressure in the mine airduct, guaranteed the atomizing de-dusting effect.

Operating principle of the present utility model is: when the liquid level sensor of main water box upper end has detected water, closed by the valve opening on the main blast pipe of liquid level sensor control, the relief valve of main water box, valve closing on the secondary blast pipe, secondary relief valve is opened, main water box is started working under the effect of blast, realized pressurization, because the effect of one way valve on main water inlet tube, main water box distinguished and admirable, current can be along the main water inlet tube adverse current, water can not flow into secondary water tank yet under the effect of the one way valve on the auxiliary waterexit pipe; When main water box carried out work, relief valve was opened and is communicated with underground atmosphere on the secondary water tank, and secondary water inlet pipe is that secondary water tank begins water filling; Carrying out with spraying work, the liquid level sensor for the treatment of the main water box lower end detects when anhydrous, be subjected to the valve closing on the main blast pipe of liquid level sensor control, main relief valve is opened, valve open on the secondary blast pipe, secondary relief valve cuts out, and this moment, secondary water tank began to realize supercharging, for atomizing de-dusting provides pressurized water, same fluid can adverse current under the effect of one way valve; And this moment, main water box also began water filling; Carrying out with spraying work, when the liquid level sensor for the treatment of main water box upper end has detected water, valve opening on the main blast pipe, main relief valve cuts out, valve closing on the secondary blast pipe, secondary relief valve is opened, and main water box is started working under the effect of blast, secondary water tank begins water filling, finishes a cyclic process; Major and minor water tank periodic duty like this has guaranteed the increase of hydraulic pressure on the one hand, has guaranteed the continuity of work on the other hand again, can be because of the anhydrous unnecessary loss of bringing.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described: mine spray dust prevention wind power boosting device, comprise main water box 1 and secondary water tank 2, the top of main water box 1 is welded with blue main water inlet tube 11 and the main blast pipe 12 of band card, roof is provided with main relief valve 13, and the bottom is welded with the blue primary flow pipe 14 of band card; The top of secondary water tank 2 is welded with blue secondary water inlet pipe 21 and the secondary blast pipe 22 of band card, and roof is provided with secondary relief valve 23, and the bottom is welded with the blue auxiliary waterexit pipe 24 of band card; Inside wall upper/lower terminal at main water box 1 respectively is provided with a MCY-Y series liquid level sensor 15 and 16, respectively be provided with a GA type straight check valve 17 and 27 on the major and minor water inlet pipe, respectively be provided with a GA type straight check valve 18 and 28 on the major and minor outlet pipe, respectively be provided with a mutual Locking type valve 19 that is subjected to the control of above-mentioned liquid level sensor and 29, two water tank sidewalls on the major and minor blast pipe and install a handle.The twayblade of the mutual locking of the unlatching of main relief valve 13 and secondary relief valve 23 by being subjected to liquid level sensor control is realized, guarantees pressure release suddenly when valve body is opened.Major and minor blast pipe is connected with the mine airduct, and major and minor outlet pipe is connected with atomizer passgae.

The function of automatic supercharging had guaranteed the atomizing de-dusting effect when the utility model utilized the airduct in the mine to realize spraying pressure of supply water deficiency, had rationally utilized resource, had improved utilization rate.

Certainly, protection domain of the present utility model is not limited to the foregoing description, so long as those of ordinary skill in the art is through creatively improving, and just should be within protection domain of the present utility model.
