The turnover gas collection induced draft device used for the deodorization and ventilation system has the advantages of being high in working efficiency, good in induced draft effect, low in labor intensity of operation and is suitable for well mouths of water-collecting wells, ventilation wells, high-level wells and the like of all storm sewage conveying pump stations.
Description
Technical field
The utility model relates to a kind of ventilation installation, relates in particular to a kind of gas collection of the reversible for deodorizing ventilation system air intake device.
Background technology
In the rain Sewage Pumping Station of municipal systems, often have the gas of a large amount of stenches, for the health that guarantees operative employee in pumping plant and the air ambient that does not affect pumping plant periphery resident, therefore the open sections such as collecting well, ventilative well, high-order well to be sealed, effectively to stop distributing of foul gas to escape, and to lay air draught (ventilation) pipeline by gas guide to deodoration system processed up to standard after again the row in atmosphere, discharge.
Conventional method for above-mentioned sealing and inlet scoop layout is directly the open section of collecting well to be carried out to capping with sheet material, and in order to guarantee sealing performance preferably, closing cap is to do jail to do extremely substantially, does not consider the dismounting flexibility of capping.But these well heads that are closed, it is again often the central core of circulation mouth that enters the work such as down-hole is keeped in repair, inspection, such as the diver goes into the well, drag for clearly, the maintenance personal goes into the well maintenance, the operational management personnel observe water level situation etc., so it is fastening usually at peripheral frame place, to adopt bolt that capping is carried out, and only need unclamp nut in the time of need to opening and just can carry out integral demounting.Yet the shortcoming of this spline structure is, the well head area is larger, and the volume and weight of capping is all heavier, open and the operation of restoring very heavy; In addition, inlet scoop arrange be generally in capping, directly open one with the corresponding hole of airduct Outside Dimensions, directly airduct is inserted to the inlet scoop as the ventilating deodorizing system, so the dismounting of capping and mobile all more difficult.
In such cases, be necessary to develop a kind of well lid of both being convenient to and open, do not affect again the device of (even strengthening) ventilating deodorizing system air draught effect.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of gas collection of the reversible for deodorizing ventilation system air intake device is provided, it adopts rotatable airduct, thereby can remove suspended hood or recovery by well heads such as collecting wells easily, reach the effect of being convenient to maintenance and improving the air draught ability.
The utility model is achieved through the following technical solutions:
A kind of gas collection of the reversible for deodorizing ventilation system air intake device, be installed on the top of collecting well, it includes horizontal airduct, rotary commutation airduct, vertical airduct, suspended hood and electric block, described horizontal airduct is connected with described deodorizing ventilation system, described rotary commutation airduct is connected in an end of this horizontal airduct, the upper end of described vertical airduct is connected with this rotary commutation airduct and can rotates around rotary commutation airduct, described suspended hood is connected in the lower end of this vertical airduct, and Open Side Down and aim at the well head of described collecting well for suspended hood, described electric block connects this suspended hood by wire rope.
Described suspended hood is inverted tubaeform.
Compared with prior art, the utility model has the advantage of:
1, airduct has adopted rotatable structure, therefore is convenient to mobile and restores, and has improved the operating efficiency of opening and sealing the well heads such as collecting well.
2, the suspended hood of inlet scoop adopts the inverted tubaeform shape, has improved the air draught effect.
3, the utility model adopts electric block traction suspended hood, has reduced the labour intensity of operation.
The accompanying drawing explanation
Fig. 1 is structural representation sketch of the present utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is working state schematic representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated, but protection domain of the present utility model is not limited to following embodiment.
Refer to the structure chart of the present utility model shown in Fig. 1 and Fig. 2, the described gas collection of the reversible for deodorizing ventilation system air intake device is installed on the top of the collecting well 6 of rain Sewage Pumping Station, be provided with spotter 9 in collecting well 6, a side of this spotter 9 is provided with spotter front shroud 8.Be provided with shrouding 11 on the well head of described collecting well 6, this shrouding 11 is fixed on the terrace 5 of well head periphery, and the steel crossbeam has been set up in described well head top.
Described gas collection air intake device includes horizontal airduct 1, rotary commutation airduct 10, vertical airduct 4, suspended hood 7 and electric block 2.Described horizontal airduct 1 is connected with described deodorizing ventilation system, described rotary commutation airduct 10 is connected in an end of this horizontal airduct 1, the upper end of described vertical airduct 4 is connected with this rotary commutation airduct 10 and can rotates around rotary commutation airduct 10, described suspended hood 7 is inverted tubaeform, it is connected in the lower end of this vertical airduct 4, Open Side Down and aim at the well head of described collecting well 6 for this suspended hood 7, on the aperture (inlet scoop) between described shrouding 11 and spotter front shroud 8, described electric block 2 is fixed on the steel crossbeam of well head top, and connect this suspended hood 7 by wire rope 3, thereby can draw this suspended hood 7 rotates.
The installation process of the described gas collection of the reversible for deodorizing ventilation system air intake device is as follows:
First collecting well 6 well heads are sealed with shrouding 11, comprised that the front end for spotter 9 carries out encapsulation process in the lump, guaranteed its effective sealing effect.A correct position is looked at shrouding 11 places at the spotter front shroud 8 that approaches spotter 9, reserves the aperture (inlet scoop) be complementary with suspended hood 7 openings.Correct position above the collecting well 6 sealed sets up the steel crossbeam, the horizontal airduct 1 that is connected to the ventilating deodorizing system is arranged firmly, the one end is installed rotary commutation airduct 10, and vertically the upper end of airduct 4 is connected with rotary commutation airduct 10, and its lower end is connected and is integral with suspended hood 7.The opening of described suspended hood 7 is aimed at the aperture (inlet scoop) on shrouding 11.A small-sized electric cucurbit is installed at steel crossbeam place, top, hangs a side that is connected in suspended hood 7 openings by wire rope 3.
Operating principle of the present utility model is as follows:
At ordinary times, vertically airduct 4 is in naturally vertical state, and wire rope 3 is in relaxed state, and suspended hood 7 just in time is placed on shrouding 11 tops, apertures.When the induced draft fan in the deodorizing ventilation system is opened, by suspended hood 7, can effectively the foul gas under collecting well 6 be discharged, and keep the relative negative pressure state in the space, down-hole, guarantee that foul gas does not leak.Need to enter that collecting well is checked for 6 times or during maintenance work when having, open small-sized electric cucurbit 2, wire rope 3 is slowly tightened up, thereby rotary commutation airduct 10 turns over certain angle, suspended hood 7 can be shifted on one side, the aperture (see figure 3) of exposing bottom, the maintenance personal can be watched or in well by the aperture on shrouding 11.
