Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing model utility.
Shown in Fig. 1-4; The utility model comprises cavity, and by intermediate clapboard 6 separated gas communication cavity 4 and the backwater cavitys 5 of being set to, suction tude 1 is installed on gas communication cavity 4 both sides with steam outlet pipe 7 symmetries in the cavity; The mouth of pipe check sealing baffle 2 that places suction tude 1 is housed in the gas communication cavity 4; With the mouth of pipe ability tight closure of suction tude 1, check sealing baffle 2 is contained on the axle 17 through the pipe spreader 16 of an end, constitutes the rotational structure of check sealing baffle around axle 17; Venting of dust explosion assembly 3 is housed directly over the gas communication cavity 4; Inlet pipeline 8 vertically is installed together with balance pneumatic circuit 12, is communicated with gas communication cavity 4 and backwater cavity 5, and backwater cavity 5 bottoms are equipped with discharging valve 10.
In order to guarantee using effect, in the described inlet pipeline 8 butterfly valve 9 is installed, equilibrium air pressure pipeline 12 is equipped with stop valve 11; Shown in Fig. 3～4, check sealing baffle 2 is made up of steel plate 13, screw 14, sealing offset plate 15, pipe spreader 16, bearing pin 17, and sealing offset plate 15 is fixed on the steel plate 13 by screw 14, and steel plate one end is equipped with pipe spreader 16, and axle 17 is contained in the pipe spreader 16; In case of necessity, automatic tailrace of negative pressure or the automatic tailrace of malleation also can be installed on the backwater cavity 5.
The utility model is when concrete the use; Be installed near the pipeline of gas suction pump entrance and exit, this device comprises suction tude, check sealing baffle, venting of dust explosion assembly, gas communication cavity, backwater cavity, steam outlet pipe, the inlet pipeline that is communicated with gas communication cavity and backwater cavity and balance pneumatic circuit, discharging valve;
Said check sealing baffle is installed in the gas communication cavity, is used to be sealed into the tracheae mouth of pipe, and forward conduction oppositely ends;
Said venting of dust explosion assembly is installed in gas communication cavity top, is used for the venting of dust explosion step-down;
Said gas communication cavity and backwater cavity are separated by intermediate clapboard, and discharging valve is equipped with in have inlet pipeline and balance pneumatic circuit, the backwater cavity bottom that are communicated with gas communication cavity and backwater cavity;
Said backwater cavity can be installed automatic tailrace of negative pressure or the automatic tailrace of malleation, to reach the function that discharges water automatically;
