Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, in particular to a discharger for an antibiotic-free feed fermentation tank. Background Art

[0002] Roughage is rich in crude fiber and protein substances such as cellulose, pectin, and lignin, which are difficult for animals to directly absorb. After fermentation treatment with microorganisms, complex enzymes and other fermentation preparations, the above substances can be converted into bacterial proteins, small peptide amino acids, and biological fermentation feed containing microbial active probiotics and complex enzyme preparations, which is conducive to the rapid conversion and rapid absorption of nutrients. Fermentation tanks are one of the main equipment for producing fermented feed.

[0003] After the fermentation tank completes the feed fermentation, the wet feed inside needs to be discharged for drying or direct filling. When discharging the fermentation tank, the displacement of the wet feed is generally controlled by a valve, and the discharge is facilitated by a screw conveyor (the wet feed is viscous). However, in actual operation, it is found that the valve and the screw conveyor interfere with each other. For example, when the screw conveyor is discharging normally, when the capacity of the feed packaging bag or other feed loading container changes, the valve must be used to reduce or increase the displacement of the wet feed. Once the displacement is reduced, the pressure in the screw conveyor is bound to increase, but it is difficult to accurately control the displacement of the screw conveyor through the speed of the motor, and there is no way to limit the upper pressure limit of the screw conveyor, so it eventually causes excessive pressure in the screw conveyor, causing the pipeline to expand and the valve to be damaged. Utility Model Content

[0024] Embodiment 1:

[0025] In this embodiment, Figure 1 and Figure 2 As shown, a discharger for an antibiotic-free feed fermentation tank comprises a fermentation tank 1, a discharger 2 is installed on the discharge end of the fermentation tank 1, a valve 3 is installed on the discharge end of the discharger 2, the discharger 2 comprises a feed pipe 4, a motor 5, a rotating shaft 6, an auger 7 and a reflux assembly 8, the feed end of the feed pipe 4 is connected to the discharge end of the fermentation tank 1, the rotating shaft 6 is rotatably installed on the feed pipe 4, the power output end of the motor 5 is connected to the outer end of the rotating shaft 6, the auger 7 is installed on the rotating shaft 6 and is located in the feed pipe 4, and a plurality of reflux assemblies 8 are installed on the auger 7.

[0026] The motor 5 drives the auger 7 to rotate in the discharge pipe 4 through the rotating shaft 6 to help the viscous wet feed to be discharged from the fermentation tank 1. At the same time, the valve 3 is used to control the discharge volume of the wet feed. When the packaging bag is replaced and the valve 3 is turned down or closed, the pressure in the discharge pipe 4 will increase. When the pressure reaches a certain level, that is, the upward squeezing force of the wet feed in the auger 7 on the reflux component 8 exceeds the downward squeezing force of the wet feed on the reflux component 8 and the elastic force of the reflux component 8 itself, the reflux component 8 can be opened to reflux the excess wet feed that causes overpressure into the fermentation tank 1.

[0027] Embodiment 2:

[0028] Based on the above embodiments, this embodiment Figure 3 As shown, the reflux assembly 8 includes a support 9, an elastic column 10 and a blocking ball 11. The support 9 is installed on the auger 7, the elastic column 10 is installed on the support 9, and the blocking ball 11 is installed on the elastic column 10. A reflux hole compatible with the blocking ball 11 is provided on the auger 7, and the blocking ball 11 is located on the reflux side of the reflux hole.

[0029] When the upward squeezing force of the wet feed in the auger 7 on the blocking ball 11 overcomes the downward squeezing force of the wet feed on the blocking ball 11 and the downward force of the elastic column 10 on the blocking ball 11, the blocking ball 11 will be pushed upward, and the excess wet feed that causes overpressure will flow back into the fermentation tank 1 through the reflux hole, thereby reducing the pressure of the wet feed on the discharge pipe 4 and the valve 3.

[0030] Preferably, a sliding column 12 is slidably mounted on the support 9 , and one end of the sliding column 12 is connected to the blocking ball 11 .

[0031] The slide column 12 plays a role of guiding and stabilizing, preventing the blocking ball 11 from shaking and deflecting when moving up and down.

[0032] Preferably, the elastic column 10 is an air bag or a spring.

[0033] Wet feed may enter the spring and affect the elastic force, but the airbag is basically not affected by the wet feed and has a better effect. The elastic column 10 can also be made of other elastic materials.

[0034] Preferably, there is at least one reflux component 8 on a circumferential surface of the auger 7 .

[0035] From a top-down or bottom-up perspective, two reflux components 8 are symmetrically arranged on a circumferential surface of the auger 7 to ensure a uniform reflux effect and force.

[0036] Preferably, the valve 3 is a manual valve.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
