Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, the present invention includes a sealed box 1, a motor 2, a telescopic hydraulic cylinder 3, a gas protection curtain 4, a stirring body 6, a supporting column 7, a reactor 8, a pulley 9 and a traction rope 10, wherein the reactor 8 is filled with fermentation Liquid 5, the fermented liquid 5 of the present invention can be anaerobic fermentation raw materials such as livestock manure, agricultural waste (straw) or industrial waste (distiller's grains).

[0017] The top of the reactor 8 has a hole, and a telescopic hydraulic cylinder 3 is installed on the lower surface of the top; there are two telescopic hydraulic cylinders 3 of the present invention, and one end of each telescopic hydraulic cylinder 3 is fixed on the lower surface of the reactor 8 top. One end is an output end, and a gas protection curtain 4 is connected t...

Abstract

The invention relates to a stirring device, and in particular, relates to a hydraulic underwater stirring device. The lower end of a supporting stand column is rotatingly arranged in a reactor, and the upper end of the supporting stand column is arranged above the reactor and located in a sealing box in a covered mode; the sealing box is connected with the reactor in a sealing mode. A stirring body is arranged in the reactor, is connected with the supporting stand column in a relatively lifting mode, and rotates along with the supporting stand column. A motor is arranged at the upper end of the supporting stand column, and the output end of the motor is connected with the stirring body through a tow rope and drives the stirring body to go up and down. The reactor is internally filled with a fermentation liquid, and the fermentation liquid in the reactor is stirred by the stirring body which can rotate and go up and down. A telescopic hydraulic cylinder is arranged on the top of the reactor, a gas protection curtain is connected to the output end of the telescopic hydraulic cylinder, and the gas protection curtain is driven by the telescopic hydraulic cylinder to go up and down. The fermentation liquid in the reactor can be fully stirred, and in the overhaul process of the stirring body, the outside-tank overhaul of the stirring body can be achieved in the premise without clearing away the fermentation liquid.

Description

technical field [0001] The invention relates to a stirring device, in particular to a hydraulic underwater stirring device. Background technique [0002] At present, there are mainly two types of mixers used in large-scale anaerobic reaction processes: vertical mixers and side entry mixers. These two types of mixers are respectively fixed on the tank top and tank wall of the anaerobic reactor, and the stirring shaft and the stirring paddle are driven by the motor and the reducer to rotate to achieve the purpose of stirring. The rotation direction of the motor and the position of the stirring paddle are fixed. Under the drive of the mixer, the stirring effect of the fermented liquid is better at the position closer to the stirring paddle, and the worse the stirring effect at the farther position, and multiple stirring will be formed. Dead angle; moreover, the stirring force on the upper part of the reactor is very small, it is easy to form crusts, and it is often necessary t...
