The invention relates to a flow control device and method for adjusting the flow rate by detecting the change of the weight of the fermentation tank per unit time, thereby controlling the opening and closing degree of the discharge port to avoid the blockage of the discharge port.

At present, the general beans are subjected to microbial fermentation to extract the products they need. The fermentation must be carried out in a fermenter or fermentation tank.

Common fermenter structures, such as the patent No. I481583 of the Republic of China on April 21, 104, "Pneumatic Liquid Fertilizer Fermentation Tank Device" patent, which discloses that there is a fermentation tank, the lower half of the fermentation tank Forming a tapered inclined portion, a conduit portion is disposed at the bottom of the inclined portion of the fermentation tank, and the conduit portion is provided with a gas pipe input gas mixed liquid fertilizer and an outlet end for discharging a solid fertilizer, and the outlet end is controlled by a valve; Thereby, it is possible to sufficiently mix the organic material, the water, and the species with the air by introducing the gas into the fermentation tank, thereby achieving the effect of complete fermentation.

The valve structure commonly used as a fermenter is the new type of feed device No. M419763 announced by the Republic of China on January 1, 101. It reveals that the diameter of a hopper is from top to bottom. The inside has an accommodating space, and has a neck having the smallest diameter at the bottom of the hopper and an outlet at the bottom end of the neck. The neck is provided with an on-off valve, whereby the on-off valve can control the leakage of material from the neck, the switch valve has a valve in the neck, the valve has a diameter smaller than the neck, so the valve can be Flip in the neck. The valve is turned upright and vertically raised, and the outlet is opened. If the outlet is to be closed, the valve is turned back to the horizontally flat position. The patent application uses a circular flap-shaped valve to achieve the function of opening or closing the outlet.

There is also a patent case No. I613013 of the Republic of China on February 1, 107, "Ball Valve for Fermentation Tank and Fermentation Tank with Ball Valve", which discloses: a body, an inner enclosure and a chamber Separating a first inlet and a first outlet respectively, the first inlet and the first outlet respectively communicate with the chamber, and the body has a liquid discharge port on a side wall thereof, and the liquid discharge port is connected to the chamber, a first valve body is disposed at the liquid discharge port; a ball is rotatably received in the chamber of the body and passes through the first-class road, and the two ends of the flow channel respectively form a second inlet and a second outlet, A gap is formed between the ball and the inner wall of the chamber; a rotating mechanism is coupled to the ball to rotate the ball between an open position and a closed position. The patent application uses a ball valve to achieve the function of opening or closing the first outlet.

However, the valve construction of the fermenter of the above-mentioned patents is mainly opened or closed manually, and it is not disclosed at all how to control the opening and closing in an automatic manner. Therefore, when the fermented material is output, it is easy to be output, and the weight in the fermenter is changed at any time, and the output speed is too fast to cause blockage, so it is not ideal in use.

Accordingly, in view of the conventional fermenter constructions described above, the above disadvantages are encountered. Therefore, the present invention provides a flow control device for a fermentation tank, comprising: a barrel body having a fermentation tank inside, the barrel body is provided with a feed port and a discharge port; and a control unit controls the feed port and The opening and closing of the discharge port; a weight sensor is disposed in the barrel body, and the weight sensor signal is connected to the control unit, so as to detect the weight change of the barrel body in a unit time at any time, and The detected weight change in the unit time is transmitted to the control unit and converted into a flow rate; a discharge control valve The discharge control valve signal is connected to the control unit, so as to receive the signal control of the control unit to control the degree of opening and closing of the discharge port.

Further, the feed inlet is provided with a feed control valve, and the feed control valve is connected to the control unit to receive signal control of the control unit to open and close the feed port.

Further, a pressure sensor is disposed on the barrel body, and the pressure sensor signal is connected to the control unit, so as to detect a pressure in the fermentation tank at any time, and transmit the detected pressure to the control unit. Make a judgment.

The barrel body is provided with an air pressure port, and the control unit controls the air pressure port to open for inputting a pressure.

The barrel system is mounted on a support frame, and the weight sensor is disposed between the barrel body and the support frame.

The invention can also be a flow control method for the fermentation tank, which is used together with the flow control device of the fermentation tank to detect the weight change of the barrel in the unit time to determine whether the flow reaches a preset. The flow value is used to control the degree of opening and closing of the discharge port to adjust the flow rate.

When the flow rate is lower than the preset flow value, the control unit controls the discharge control valve to increase the opening degree of the discharge port to increase the flow rate; and when the flow rate is higher than the preset flow rate value, The control unit then controls the discharge control valve to reduce the opening degree of the discharge port to reduce the flow rate; thereby adjusting the flow rate to remain within the preset flow rate value at any time.

The above preset flow rate value is 10000 kg/hr or less.

The pressure in the fermentation tank is detected at any time to control the fermentation tank to maintain a preset pressure value.

The above technical features have the following advantages:

1. The weight change of the fermenter in unit time is detected at any time, so as to convert into the flow of the fermented material, and according to the change of the flow rate, the degree of opening and closing of the discharge port is controlled, thereby adjusting the flow rate so that the flow rate is kept at the preset Within the flow value, the flow rate of the fermented material can be prevented from being too fast or too slow to block the discharge port.

2. The pressure sensor can detect the pressure change in the fermentation tank at any time. When the pressure is insufficient, the pressure can be replenished at a proper time, so that the fermentation process can maintain the pressure and reach the preset pressure value, which is beneficial to the fermentation operation. get on.
