[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0020] like Figure 1-6As shown, a joint device for a fermentation tank unit includes a main pipe 1, on which a plurality of stacked progressively connected components are arranged, and the number of layers of the progressively connected components is at least 1. The progressively connected component includes a base 2 arranged on the main pipe 1, on the outer wall of the base 2, a first arc groove 4, a second arc groove 41, a third arc groove 42 and a fourth arc groove 43 are arranged in sequence along the circumference of the base 2, and the openings of the four arc grooves are all on the outer wall of the base 2, the opening length of the first arc groove 4> the second arc groove 41> the third arc groove 42> the fourth arc groove 43, that is, the opening lengths of the arc grooves decrease in sequence along a single direction, and the interval length between the opening of the fourth arc groove 43 and the opening of the first arc groove 4 is less than the interval length between the opening of the first arc groove 4 and the opening of the second arc groove 41<the interval length between the opening of the second arc groove 41 and the opening of the third arc groove 42<the interval length between the opening of the third arc groove 42 and the opening of the fourth arc groove 43, that is. The interval lengths of adjacent arc-shaped slot openings increase in sequence in the same direction. The opening length of the arc-shaped slot and the interval length of the corresponding adjacent arc-shaped slot openings have opposite changing trends, and this trend also holds true when the arc-shaped slots are set in opposite directions. A connecting pipe 5 is connected between one end of the arc-shaped slot and the main pipe 1, and an adjusting ring 3 is sealingly rotatably connected to the outer edge of the base 2. A plurality of fluid outlet pipes 31 are evenly arranged along the circumference of the adjusting ring 3. When the adjusting ring 3 and the base 2 rotate relative to each other, the fluid outlet pipes 31 are correspondingly connected to the arc-shaped slots.

[0021] In this embodiment, the length of the arc groove opening is the same as the length of the arc groove, the number of fluid outlet pipes 31 and arc grooves is the same, both are 4, and the angle between adjacent fluid outlet pipes 31 is 90°. The number of fluid outlet pipes 31 and arc grooves can be set to 3 or 5 or other numbers as needed, and the angle between adjacent fluid outlet pipes 31 is correspondingly adjusted to 120° or other angles.

[0022] In this embodiment, two annular sliding strips 22 are symmetrically provided on the outer side wall of the base 2 , and the sliding strips 22 are sealingly and slidably connected to the inner side wall of the adjustment ring 3 .

[0023] In this embodiment, the upper end of the main pipe 1 is closed and the lower end is open, and a fixing ring 11 is provided at the lower end of the main pipe 1. The fixing ring 11 is fixedly connected to the downstream fluid output pipeline of the chiller or air compressor.

[0024] In this embodiment, a plurality of scale bars 21 are evenly arranged along the circumferential direction on the top surface of the base 2. The scale bars 21 are used to indicate the rotation angle of the adjustment ring 3 and the fluid outlet pipe 31, so as to adjust the number of connections between the fluid outlet pipe 31 and the main pipe 1 and reset the closed fluid outlet pipe 31.

[0025] In this embodiment, a fixing bracket 6 is provided at the bottom of the base 2 for supporting and fixing the entire joint device.

[0026] Working process and principle: In the initial state, the fluid outlet pipes 31 are all located outside one end of the arc groove, so that the fluid outlet pipes 31 are just not connected to the arc groove, and all the fluid outlet pipes 31 are blocked at this time. The lower end of the main pipe 1 is fixedly connected to the downstream fluid output pipeline of the air compressor or chiller through the fixing ring 11, and then the fluid outlet pipes 31 are respectively connected to the input pipeline of the fermentation tank unit, and the gas or liquid is introduced into the main pipe 1, and the adjustment ring 3 is slowly rotated clockwise at a smaller angle until the fluid outlet pipe 31 is connected to the first arc groove 4. At this time, the fluid can flow out from the fluid outlet pipe 31 to the fermentation tank unit through the connecting pipe 5 and the first arc groove 4. Since the intervals between other adjacent arc grooves are longer, the second arc groove 41, the third arc groove 42 and the fourth arc groove 43 are not connected to the fluid outlet pipe 31. If you want to increase the number of fluid outlets 31 connected, continue to rotate the adjustment ring 3 in the clockwise direction at a smaller angle until the second arc groove 41 is connected to the corresponding second fluid outlet 31. Similarly, the third arc groove 42 and the fourth arc groove 43 are still not connected to the fluid outlet 31. Since the opening length of the first arc groove 4 is the largest, the first arc groove 4 will be connected to the corresponding fluid outlet 31 during the subsequent rotation of the adjustment ring 3. Therefore, by continuing to rotate the adjustment ring 3 in the same direction, a connected fluid outlet 31 is added. By analogy, continue to rotate the adjustment ring 3 so that the four fluid outlets 31 are connected to the main pipe 1 through the first arc groove 4, the second arc groove 41, the third arc groove 42 and the fourth arc groove 43, respectively, to reach the maximum number of connections. However, the rotation angle of the adjustment ring 3 is less than 90° at this time. When it is necessary to reset and close all fluid outlets 31, it is only necessary to continue to rotate the adjustment ring 3 to 90° to reach the initial blocking state. The relative rotation angle of the adjustment ring 3 can be observed through the scale bar 21. Similarly, when more than four fluid outlet pipes 31 need to be connected, the adjustment rings 3 of other layers can be rotated to arbitrarily increase or decrease the number of connected fluid outlet pipes 31 as needed.
