Abstract
The utility model discloses a vacuum feeding device of a marsh gas tank reactor circulating system, which comprises an adjusting tank and a fermenting tank. A feeding pipe is connected on the adjusting tank. The other end of the feeding pipe is connected with a vacuum feeder. The two ends of the discharging pipe and a circulating pipe are respectively connected with the fermenting tank and the vacuum feeder. A centrifugal pump is installed on the discharging pipe. When the centrifugal pump operates, liquid is absorbed into the vacuum feeder from the adjusting tank and the liquid in the vacuum feeder enters the fermenting tank along the discharging pipe after the gate valve of the circulating pipe is closed; and when the centrifugal pump is shut down and the gate valve of the circulating pipe is opened, the liquid enters the vacuum feeder along the circulating pipe. Thereby, the internal circulating system of the fermenting tank is formed. Compared with the prior art, since the internal circulating system uses one less pump, the utility model has the advantage that the cost is saved.
Description
Technical field
The utility model relates to a kind of liquid feeding device, especially a kind of methane-generating pit reaction device recycle system vacuum feeder.
Background technology
Biogas cleans clean new forms of energy and is obtaining more and more widely application as a kind of, and the pump that extracts liquid at present in the methane-generating pit all is the submersible sewage pump that places liquid level following, very easily be damaged because of placing below the liquid level for a long time, and also easy-maintaining not after the damage.Internal circulation system all has two pumps in the existing biogas technology, and cost is higher, and device is complicated.
The utility model content
Technical assignment of the present utility model is to provide a kind of methane-generating pit reaction device recycle system vacuum feeder at the deficiency in the above-mentioned technology.
The technical scheme that the utility model technical solution problem is adopted is: a kind of methane-generating pit reaction device recycle system vacuum feeder, comprise equalizing tank, fermentation vat, be connected with feed-pipe on the described equalizing tank, the feed-pipe the other end connects the vacuum feed device, discharge nozzle, circulation tube two ends connect fermentation vat and vacuum feed device respectively, and impeller pump is installed on the discharge nozzle.
On the described circulation tube gate valve is installed.
On the described vacuum feed device strainer is installed.
On the described circulation tube butterfly valve is installed.
Gate valve and butterfly valve are installed on the described discharge nozzle.
The beneficial effect that the utility model can bring is:
1, the utility model changes the submersible sewage pump that is placed in the prior art below the liquid level into be placed on more than the liquid level impeller pump, and impeller pump is difficult for rust corrosion, and easy to maintenance.
2, the described recycle system has only an impeller pump, can save cost, and simple in structure.
Description of drawings
Fig. 1: the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done following detailed description:
The utility model comprises equalizing tank 5 as shown in Figure 1, fermentation vat 11 is connected with feed-pipe 4 on the described equalizing tank, feed-pipe 4 the other ends connect vacuum feed device 1, discharge nozzle 6, circulation tube 12 two ends connect fermentation vat 11 and vacuum feed device 1 respectively, and impeller pump 8 is installed on the discharge nozzle.When opening impeller pump 8, liquid can be inhaled into the vacuum feed device 1 from equalizing tank 5, the filtration of liquid process strainer 2 is the left side of big granular solids filter at strainer 2, filter residue can manually be discharged from inspection window 3 after for some time, close the gate valve 13 of circulation tube 12, liquid in the vacuum feed device 1 will enter in the fermentation vat 11 along discharge nozzle 6, and wherein gate valve 9, butterfly valve 7 and butterfly valve 14 are the normally open valve door, as make-up valve; Wherein vacuum breaker 10 can prevent that the liquid in the discharge nozzle 6 from flowing backwards.When closing impeller pump 8, open the gate valve 13 of circulation tube 12 simultaneously, liquid can enter into vacuum feed device 1 along circulation tube 12, and be the internal circulation system of fermentation vat 11 this moment, this internal circulation system lacks than the internal circulation system of prior art uses a pump, has saved cost.
Claims (5)
1. a methane-generating pit reacts device recycle system vacuum feeder, comprise equalizing tank, fermentation vat, it is characterized in that: be connected with feed-pipe on the described equalizing tank, the feed-pipe the other end connects the vacuum feed device, discharge nozzle, circulation tube two ends connect fermentation vat and vacuum feed device respectively, and impeller pump is installed on the discharge nozzle.
