DETAILED DESCRIPTION

[0034] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0035] Example:

[0036] like Figure 1 A stirring device for sewage hydrolysis and acidification is shown, wherein a water inlet 2 and a water outlet 3 are respectively provided on the side walls of the hydrolysis and acidification tank 1 at both ends, and the stirring device comprises a stirrer assembly arranged in the hydrolysis and acidification tank 1;

A driving assembly for driving the slide bar 4 to rotate and the agitator assembly to slide up and down is arranged on the top of the hydrolysis acidification tank 1.

[0038] In this embodiment, a plurality of sequentially connected hydrolysis acidification tanks 1 may be provided during the sewage hydrolysis acidification treatment process, and a stirring device may be provided in each hydrolysis acidification tank 1 to stir the sewage.

[0039] like Figure 1 and Figure 3 As shown, the upper and lower ends of the slide bar 4 are respectively mounted on the upper and lower end surfaces of the hydrolysis acidification tank 1 through bearings, and the upper end of the slide bar 4 extends out of the upper end surface of the hydrolysis acidification tank 1;

A plurality of step guide wheels 6 are installed on the upper end surface of the hydrolysis acidification tank 1. The plurality of step guide wheels 6 are arranged in a circular array along the axis of the slide bar 4. The rotating disc 5 is placed on the step surfaces of the plurality of step guide wheels 6.

[0041] In this embodiment, a step guide wheel 6 is provided to support the rotating disc 5 and the driving assembly above it, so as to reduce the longitudinal force on the slide bar 4. At the same time, the step guide wheel 6 is rotatably installed on the upper end surface of the hydrolysis acidification tank 1 to guide the rotating disc 5 when it rotates. When the rotating disc 5 rotates, it drives the slide bar 4 and the agitator assembly mounted on the slide bar 4 to rotate synchronously.

[0042] like Figure 1 , Figure 3 and Figure 5 As shown, the driving assembly includes a gear ring 7 sleeved and mounted on the outer wall of the rotating disc 5, and the gear ring 7 is located above a plurality of step guide wheels 6;

[0043] A first brake motor 8 is installed on the hydrolysis acidification tank 1 . A gear 9 is installed at the power output end of the first brake motor 8 . The gear 9 is meshed with the gear ring 7 .

[0044] In this embodiment, when the angle of the agitator assembly needs to be adjusted, the first brake motor 8 is started, and the gear 9 engages with the gear ring 7 to drive the rotating disk 5, the slide rod 4 and the agitator assembly to rotate horizontally, thereby adjusting the horizontal angle of the agitator assembly.

[0045] like Figure 1 and Figure 2 As shown, the stirrer assembly includes a slide groove tube 23 slidably sleeved on the slide rod 4;

[0046] A first mounting plate 10 is mounted on the end surface of the chute tube 23 close to the water inlet 2, and a second mounting plate 11 is rotatably mounted on the end surface of the first mounting plate 10 close to the water inlet 2, and the rotation axis of the second mounting plate 11 is perpendicular to the vertical direction;

[0047] A waterproof motor 12 is installed on the second installation plate 11 , and a stirring blade 13 is installed on the power output shaft of the waterproof motor 12 .

[0048] In this embodiment, during the sewage hydrolysis and acidification process, the waterproof motor 12 is started to drive the stirring blade 13 to rotate so that the sewage and the microorganisms are fully mixed.

[0050] The second driving mechanism 14 is provided with a first steel wire 18, and the front end of the first steel wire 18 is connected to the chute tube 23 after being guided by the first guide wheel module 15;

[0051] The third driving mechanism 16 is provided with a second steel wire 19 , and the front end of the second steel wire 19 is connected to the second mounting plate 11 after being guided by the second wire pulley module 17 .

[0054] In the present embodiment, the second drive mechanism 14 and the third drive mechanism 16 can be manual drive mechanisms or automatic drive mechanisms. When it is necessary to adjust the vertical position of the agitator assembly, the second drive mechanism 14 and the third drive mechanism 16 on both sides are adjusted synchronously, and the first steel wire 18 and the second steel wire 19 synchronously drive the chute tube 23 and the second mounting plate 11 to rise or fall, and the entire agitator assembly on the second mounting plate 11 remains horizontal when it rises or falls to the predetermined position. When it is necessary to adjust the pitch angle of the entire agitator assembly, the second drive mechanism 14 stops, and the third drive mechanism 16 drives the second mounting plate 11 to rise or fall, so that the entire agitator assembly on the second mounting plate 11 is tilted up or down, so as to adjust the pitch angle of the entire agitator assembly.

[0058] In this embodiment, when the output axis of the waterproof motor 12 is parallel to the axis of the water inlet 2 or the water outlet 3, it is the initial position of horizontal rotation, and the rotation angle of the rotating disk 5 is plus or minus 120°. During the rotation of the rotating disk 5, the first steel wire 18 and the second steel wire 19 are driven to rotate together. Therefore, an avoidance ring groove 21 is opened on the upper end surface of the hydrolysis acidification tank 1, and the central axis of the avoidance ring groove 21 coincides with the rotating disk 5.

[0059] like Figure 1 , Figure 2 and Figure 4 As shown, a rotation-stopping boss 41 is provided on the outer end surface of the slide rod 4 in the vertical direction, an angle sensor 22 is installed on the second mounting plate 11, and a sealing waterproof cover is provided on the outer side of the angle sensor 22.

The angle sensor 22 is used to collect the pitch angle information of the second mounting plate 11 and transmit it to the control module through the data transmission line. The data transmission line is sealed and passes through the sealed waterproof cover.
