Technical Field

The utility model relates to the technical field of anaerobic fermentation, in particular to a collection and reflux device for liquid in a positive and negative pressure protector.

Background technique

Biogas is a mixed gas produced by the fermentation of organic matter by microorganisms under anaerobic conditions. From a scientific definition point of view, biogas is a combustible gas produced by the fermentation of various organic substances by microorganisms in an isolated environment (reducing conditions) at a suitable temperature and pH value.

During the fermentation process of the anaerobic fermentation system, there are cases of uneven fermentation and unstable fermentation. The material is deposited in the tank, which is prone to produce "gas bursts" (a large amount of biogas flows into the anaerobic chamber instantly). A large amount of biogas cannot be instantly input into the gas storage system from the biogas pipe, causing the gas pressure in the tank to increase, even reaching more than 10 kPa, and instantly flushing the antifreeze in the positive and negative pressure protector out of the protector, causing the antifreeze to be wasted, and the biogas is continuously emptied, which increases the risk relatively. To this end, we provide a collection and reflux device for the liquid in the positive and negative pressure protector to solve the above problems.

Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As shown in Figures 1-2, the utility model provides a technical solution: a collection and reflux device for liquid in a positive and negative pressure protector, comprising a negative pressure protector 1 and a positive pressure protector 2, a first cover body 3 is installed on the negative pressure protector 1, and a second cover body 6 is installed on the positive pressure protector 2, the first cover body 3 is detachably connected to the negative pressure protector 1, and the second cover body 6 is detachably connected to the positive pressure protector 2, a liquid level detector 8 is installed on the second cover body 6, and the detection end of the liquid level detector 8 is located in the positive pressure protector 2, the liquid level detector 8 can monitor the amount of coolant in the positive pressure protector 2 in real time, and a connecting component for connecting the negative pressure protector 1 and the positive pressure protector 2 is arranged between the negative pressure protector 1 and the positive pressure protector 2, the connecting component comprises a delivery pipe 5, one end of the delivery pipe 5 is installed with a first connecting pipe 4, and the first connecting pipe 4 is fixedly connected to the first cover body 3, the other end of the delivery pipe 5 is installed with a second connecting pipe 7, and the bottom end of the second connecting pipe 7 passes through the second cover body 6 and extends to the inside of the positive pressure protector 2.

A return pipe 9 is fixedly connected to the second cover body 6, and a collecting box 10 is fixedly connected to the return pipe 9. There are two angles on the top of the collecting box 10, which can block the coolant entering the collecting box 10 and prevent the coolant from entering the exhaust port 14. A block 11 is arranged in the collecting box 10, and the block 11 is located above the return pipe 9. The coolant entering the collecting box 10 through the return pipe 9 will directly impact on the block 11, thereby separating the coolant and the gas. Moreover, the top of the block 11 is a conical structure, which can reduce the coolant remaining on the block 11.

An exhaust port 14 is opened on the collection box 10, and a shielding assembly for shielding the exhaust port 14 and a supporting assembly for supporting the shielding assembly and the block 11 are provided on the collection box 10. The shielding assembly includes a sealing cover 15, and the sealing cover 15 is located above the collection box 10. A guide plate 16 is fixedly connected to the sealing cover 15. Since the sealing cover 15 covers the collection box 10, the exhaust port 14 can be shielded at the top of the exhaust port 14 to prevent external debris from entering the exhaust port 14.

The support assembly includes a connecting plate 13, to which a connecting rod 12 is fixedly connected, the bottom end of the connecting rod 12 passes through the exhaust port 14 and is fixedly connected to the stopper 11, and a sealing cover 15 is fixedly connected to the connecting rod 12. The support assembly also includes a support seat 18 fixedly connected to the collection box 10, a sliding rod 17 is slidably connected in the support seat 18, the top end of the sliding rod 17 is fixedly connected to the connecting plate 13, the bottom end of the sliding rod 17 is fixedly connected to a limiting block 19, a spring 20 is sleeved on the sliding rod 17, and the two ends of the spring 20 are respectively fixedly connected to the support seat 18 and the limiting block 19.

The elasticity of the spring 20 is used to support the limit block 19, so that when the block 11 pushes the connecting rod 12 upward, the connecting plate 13 drives the sliding rod 17 to move upward and compress the spring 20. When there is no external force on the block 11, the sealing cover 15 can fall down quickly to cover the exhaust port 14.

Working principle: When a gas burst occurs, the coolant in the positive pressure protector 2 will impact the interior of the collecting box 10 through the reflux pipe 9, and the coolant will impact the block 11, and then the block 11 will make the connecting rod 12 drive the sealing cover 15 and the block 11 to move upward, so that the gas mixed in the coolant will be discharged from the collecting box 10 through the exhaust port 14, and the coolant in the collecting box 10 will flow back to the interior of the positive pressure protector 2 again through the reflux pipe 9, so that the coolant protects the positive pressure protector 2 again, reducing the waste of coolant, and the sealing cover 15 always blocks and closes the exhaust port 14 under normal operation, which can effectively reduce the entry of external debris into the interior of the collecting box 10 and avoid contamination of the coolant.
