Description

A constant temperature automatic slag discharge biogas digester

technical field

The utility model relates to a methane fermentation tank device, in particular to a constant temperature automatic slag discharge methane tank, which belongs to the technical field of mechanical design.

Background technique

Biogas digesters are a major place to generate biogas and have been widely used in many areas of our country. The use of biogas can save a lot of energy, and the remaining biogas residue is also a good organic fertilizer. When we use biogas digesters, we need to pay attention to two important issues. The first is the temperature. Generally, the gas production rate of biogas is the best at around 35°C. The second is the need to clean up too much biogas residue and biogas in time. liquid. However, in view of the fact that most of the biogas digesters are used by ordinary users, if high-end equipment is used to transform and process the biogas digesters, the cost will be too high. Therefore, we need a low-cost biogas fermentation tank that can control and adjust the temperature and can automatically discharge excess biogas slurry and biogas residue in time.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a device for constant temperature and automatic discharge of biogas ponds. The device can maintain constant temperature in the pond, automatically discharge materials, and has a simple structure and low cost.

The utility model is realized through the following technical solutions: a constant temperature automatic slag discharge biogas tank, including a fermentation tank 1, a solenoid valve 5, a heater 6, an agitator 7, a lower liquid level switch 8, an upper liquid level switch 9, and a temperature sensor 10, controller 11 and motor 12; Described fermenting tank 1 is provided with material inlet 2, and heater 6 is installed in fermenting tank 1, and is connected by master controller 11; Stirrer 7 is installed in fermenting tank 1, and The motor 12 is connected to the general controller 11; the temperature sensor 10 is set in the fermentation tank 1 and connected to the general controller 11; the lower liquid level switch 8 and the upper liquid level switch 9 are installed on the inner wall of the fermentation tank 1, and are connected by the general control The device 11 is connected; the controller 11 and the motor 12 are arranged above the fermentation tank 1 .

The fermentation tank 1 is installed on a support 3 .

Its working process is as follows: First, put the fermented material required for biogas fermentation into the fermentation tank 1 through the feed port 2, so that it can be fermented in the fermentation tank 1, the lower liquid level switch 8 and the upper liquid level switch set in advance 9 and the solenoid valve are controlled by the controller 11. When the liquid level in the fermentation tank 1 is higher than the upper liquid level switch 9, the controller 11 controls the solenoid valve 5 to open to discharge excess biogas slurry and biogas residue. When the liquid level is low At the height of the liquid level opening light 8, the controller 11 controls the solenoid valve 5 to close. Through the setting on the controller 11, the temperature of the constant temperature can be set, and the motor 12 can be started at regular intervals. The temperature sensor 10 is in the fermentation tank 1 in real time. Monitor the temperature. When the temperature is lower than the set temperature, the heater 6 will start to heat the fermented product in the fermentation tank 1. When the motor 12 is running, it will drive the agitator 7 to stir the mixed fermented product in the fermentation tank 1. When the user needs to use biogas , it can be used at the biogas outlet 13, and the whole fermentation tank 1 is supported on the ground 4 by the support 3.

Compared with the prior art, the utility model has the following advantages: the device can be adjusted at any time according to the temperature in the biogas tank to maintain a constant temperature state in the tank, and at the same time has the control function of the liquid level switch to automatically discharge excess biogas residue according to the liquid level in the tank and biogas slurry; it can not only maintain a high biogas production rate in the pond, but also save manpower to regularly clean up excess biogas residue and biogas slurry.
