in the reciprocating aerator, a plunger is slidably positioned in a plunger groove of a machine shell, an air inlet hole and an air outlet hole which are communicated with the plunger groove are arranged on the machine shell, and check valves are arranged on the air inlet hole and the air outlet hole.
The air outlet is connected with an air duct extending to the bottom of the tank body.
The impeller is fixed in the middle of the transmission shaft, the reciprocating aerator is horizontally arranged to enable the plunger to reciprocate in the horizontal direction, the machine shell is fixed with the inner wall of the tank body, the air inlet is formed in the top of the machine shell, and the air outlet is formed in the bottom of the machine shell.
The transmission mechanism comprises an eccentric wheel fixed at the end part of the transmission shaft, a guide sleeve concentrically sleeved outside the bearing through the bearing, and a rotating pin fixed at the tail part of the plunger connecting rod and rotatably positioned on the guide sleeve.
The invention has the beneficial effects that:
most of the biogas digesters adopt livestock and poultry manure as raw materials, the raw materials have higher ammonia nitrogen content and can generate more ammonia, and meanwhile, the biogas digesters have higher pressure and the ammonia is easier to dissolve in water, so that the invention controls the intermittent operation of the reciprocating aerator through the regulating valve, thereby continuously pressing the biogas into the biogas slurry to ensure that the liquid level is in an unstable stateEffectively prevent incrustation and promote H2S reacts with ammonia in the biogas slurry to reduce and eliminate H in the biogas2S, the heat generated by the reaction can further ensure the temperature stability of the methane tank and promote the normal growth of microorganisms.

Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following examples.
As shown in figure 1, the aeration type anti-crusting methane tank comprises a tank body 1, an outlet 10 is arranged at the top end of the tank body, a top cover 15 seals the outlet, a methane pipe 14 is arranged on the top cover and used for leading out methane, a feed pipe 11 and a discharge pipe 12 are also arranged on the tank body, the inlet of the feed pipe is communicated with a feed tank, the outlet of the discharge pipe is communicated with a discharge tank 9, and an adjusting valve 13 is arranged in the feed pipe.
The tank body is internally provided with an impeller 3, a transmission shaft 2, a transmission mechanism 4 and a reciprocating aerator 5. The transmission shaft can be rotationally positioned in the tank body around a horizontal axis, and the impeller is fixed in the middle of the transmission shaft and is positioned below the outlet of the feeding pipe. The two horizontally-placed reciprocating aerators are symmetrically arranged on the impeller and are respectively positioned at two ends of the transmission shaft. The transmission mechanism is arranged between the transmission shaft and the reciprocating aerator and drives the reciprocating aerator to work by transmitting the power of the impeller.
As shown in fig. 3, in the reciprocating aerator, a casing 51 is fixed with the inner wall of the tank body, a plunger groove 54 extending horizontally is arranged on the casing, the length direction of the plunger groove is perpendicular to the length direction of the transmission shaft, an air inlet 52 and an air outlet 53 communicating the plunger groove are also arranged at the right end of the casing, the air inlet is arranged at the top of the casing, the air outlet is arranged at the bottom of the casing, and check valves 55 are arranged on the air inlet and the air outlet; the air duct 6 is communicated with the air outlet hole, and the bottom end of the air duct vertically extends downwards to the bottom of the pool body; the check valve on the air inlet hole is used for sucking air from the inner cavity of the tank body, and the check valve on the air outlet hole is used for discharging the sucked air; the plunger 7 is slidably positioned in a plunger slot, the size of the plunger is adapted to the size of the plunger slot, the right end of the plunger link 71 is fixed to the plunger and the left end of the plunger link protrudes out of the plunger slot.
The transmission mechanism is arranged between the transmission shaft and the reciprocating aerator and drives the reciprocating aerator to work by transmitting the power of the impeller. In the transmission mechanism, an eccentric wheel 21 is fixed at the end part of a transmission shaft, the eccentric wheel is arranged on the inner ring of a bearing 22, a guide sleeve 23 is concentrically sheathed on the outer ring of the bearing 22, an annular groove 24 surrounding the outside of the bearing is arranged on the guide sleeve, a rotating pin 72 fixed at the tail part of a plunger connecting rod is slidably positioned in the annular groove, and the length direction of the rotating pin is parallel to the length direction of the transmission shaft; and a bearing bush is further arranged on the rotating pin to improve the wear resistance.
The impeller drives the eccentric wheel and the guide sleeve to rotate simultaneously through the transmission shaft when rotating, and because the plunger can only move in the horizontal direction, the eccentric wheel and the guide sleeve convert the rotary motion into the horizontal motion through the cooperation with the rotating pin, thereby pushing the plunger to horizontally reciprocate in the casing, when the plunger moves left, the check valve on the air inlet hole is opened to suck the gas in the pool into the plunger groove, and when the plunger moves right, the check valve on the air outlet hole is opened to discharge the gas in the plunger groove.
The working principle of the invention is as follows:
when the liquid level of the feeding tank reaches a certain height, the regulating valve is opened, the liquid in the feeding tank flows into the tank body through the feeding pipe and pushes the impeller to rotate, the rotating impeller drives the reciprocating aerator to work through the transmission shaft and the transmission mechanism, and the reciprocating aerator continuously presses the biogas above the liquid level in the tank body into the liquid so that the liquid is in a turbulent flow state, can effectively prevent incrustation and remove H2And (4) S gas.
