Description

A biogas generator

technical field

The utility model relates to a biogas generating device, in particular to a biogas generating device capable of automatically eliminating or alleviating the encrusting phenomenon of biogas slurry and easily removing slag.

Background technique

The working principle of the biogas digester: When biogas is generated in the pond, the biogas in the gas storage room increases continuously, and the pressure continues to increase, forcing the liquid level in the main pool to drop, and squeeze out a part of the material liquid into the hydraulic room. When people turn on the stove, the pressure in the biogas digester gradually drops, and the feed liquid in the water pressure chamber continuously flows back to the main pond. In this way, gas is produced and used continuously, so that the pressure balance between the fermentation room and the output room is always maintained.

Since the fermentation temperature changes with the temperature of the four seasons, in winter and spring, when the outdoor temperature is lower than 15°C, the biogas slurry will produce crusting, which will affect the gas production rate of the biogas digester, and the gas production rate at this time is low , generally only about 0.15m ³ /m ³ per day. Due to the structure of the biogas digester and the corrosion of the biogas slurry, many biogas digesters are not equipped with a stirring device, which makes it impossible to break the shell of the biogas slurry, so that the encrustation of the biogas slurry cannot be eliminated, and the due effect of the biogas digester cannot be brought into play.

In addition, the feed and discharge of biogas digesters are currently discontinuous. Most biogas digesters will stop producing gas when they are discharging. After the new material enters the biogas digester, it takes 3-5 days to produce gas, resulting in discontinuous gas production, and the discharge of materials is troublesome and labor-intensive, which is not conducive to popularization. Therefore researching a new type of biogas digester, solving the difficult problems of breaking the shell and inconvenient slag removal of the existing biogas digesters, and realizing high efficiency, simplicity, economy, beautification and durability have become a problem to be solved.

Utility model content

The technical problem to be solved by the utility model is to provide a biogas generating device that can automatically eliminate or reduce crusting, is easy to discharge slag, and can realize slag discharge without affecting the use of biogas in the biogas tank.

The technical solution adopted by the utility model to solve the technical problem is: a biogas generating device, including a feed inlet, a pool body, a gas outlet device, a material outlet, a shell breaker, and a slag outlet device, which is characterized in that: The shell breaker is a U-shaped tube, one end of the U-shaped tube is connected to the biogas slurry in the pool, and the other end is connected to the biogas outlet. The biogas slurry in the pool flows from the pool to the U-shaped tube with the change of air pressure, thereby stirring the biogas. The purpose of the liquid is to eliminate or reduce crusting.

There is a certain height of biogas slurry in the U-shaped tube. When the user is using biogas, the biogas slurry entering the U-shaped tube will increase due to the decrease in the air pressure in the biogas tank; when the user stops using gas, the air pressure in the biogas tank will decrease. The rise makes the liquid level in the U-shaped tube lower, so that the biogas slurry flows out of the U-shaped tube, impulsing the liquid level of the biogas slurry in the biogas tank, and achieves the effect of automatically breaking the shell, thereby increasing the gas production rate of the biogas tank.

Further, the cantilever slag extractor of the slag discharging device includes a support base, a driving wheel, a driving cable, and a slag discharge hopper, one of the driving wheels is installed on the support base and connected with the cable support of the driving cable, and the other The driving wheel is connected to the cable support of the driving cable, and the driving cable is provided with a slag discharge hopper, which has a certain number and size of holes, which is convenient for filtering liquid and discharging biogas slag.

Such a structure enables the user to discharge slag without stopping the air, and the labor intensity is small and the use is convenient.

Still further, for the convenience of feeding, the feed port includes a section of vertical blanking channel and a section of inclined blanking channel, the vertical blanking channel is arranged at the entrance of the feed port, and the inclined blanking channel The lower end is connected to the cell body. With such a structure, it is convenient for the raw material to enter the pool body smoothly under its own weight after entering the feed port.

Furthermore, in order to facilitate discharging, the bottom plate of the pool body is made to be inclined relative to the pool body, and the position of one end connected to the feed inlet is higher than the other end. With such a structure, it is convenient for the raw material to slide down to the discharge port along the bottom plate after entering the tank body.

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Detailed ways

As shown in the drawings, in an embodiment of the present utility model, the pool body is divided into an upper pool body 1 and a lower pool body 4, and the upper pool body 1 and the lower pool body 4 are connected by connecting bolts 15. The lower end of the feed pipe 3 is connected to the feeder 2, and the lower end of the feeder 2 is connected to the lower tank body 4, and the lower tank body 4 is provided with a slope bottom plate 5. The slope bottom plate 5 is at a certain inclination angle relative to the ground, the high end is connected to the feeder 2 , the other end at the low position is connected to the conveying cable 10 , and the other end of the conveying cable 10 is connected to the discharge tank 13 . The cantilever slag extractor includes a support base 11 , a drive wheel 12 , a drive cable (including cable support) 10 and a slag hopper 16 . Wherein two driving wheels 12 are positioned at the two ends of driving cable (including cable support) 10, and one end of driving wheel 12 is installed on the supporting seat 11. A slag discharge hopper 16 is provided on the conveying cable 10 . The slag discharge hopper 16 is a hole with a certain number and size, which is convenient for filtering liquid and discharging biogas slag.

The operation of the slag discharge method is simple and convenient.

The U-shaped tube 6 is equipped with a certain height of biogas slurry. When the user is using biogas, the liquid enters the U-shaped tube 6 due to the decrease of the air pressure in the biogas tank, increasing the biogas slurry; when the user stops using gas, the biogas As the air pressure in the pool rises, the liquid level in the U-shaped tube 6 decreases, so that the biogas slurry flows out of the U-shaped tube 5, impulsing the liquid level of the biogas slurry in the biogas tank to achieve the effect of automatic shell breaking, thereby increasing the gas production rate of the biogas tank.
