TECHNICAL FIELD

[0001] The present application relates to centrifugal separation technology, in particular to a fermentation liquid centrifugal separation device. BACKGROUND

[0002] In the production process of Hartz acid aqueous organic fertilizer, after the fermentation liquid is fermented, the fermentation liquid needs to be centrifuged by a centrifugal separation device to separate the mycelium mud and the supernatant, and the supernatant is used for subsequent production of Hartz acid aqueous organic fertilizer.

[0003] At present, a butterfly centrifuge is usually used for centrifugal separation of the fermentation liquid. The power for discharging the mycelium mud from the butterfly centrifuge is usually basically from the pressure of the mixed liquid in the drum of the butterfly centrifuge. However, the pressure of the mixed liquid is small, and after the butterfly centrifuge is used for a long time, the mycelium mud is easy to accumulate in the slag discharge pipe of the butterfly centrifuge, thereby blocking the slag discharge pipe. When the slag discharge pipe is blocked, the machine needs to be stopped, and the slag discharge pipe needs to be manually cleaned, which not only wastes time and effort, but also affects the efficiency of centrifugal separation. CONTENT OF THE UTILITY MODEL

[0005] The present application provides a fermentation liquid centrifugal separation device, which comprises a rack, a butterfly centrifuge is installed on the rack, and a slag discharge pipe is connected to the butterfly centrifuge.

[0006] A material collecting tank is connected to the discharge port of the slag discharge pipe, and a valve I is connected to the lower end of the material collecting tank.

[0007] The upper part of the material collecting tank is connected to a negative pressure tank capable of generating negative pressure through a valve II.

[0008] Optionally, the negative pressure tank comprises a tank body, the upper part of the tank body is connected to the valve II, an air extraction port is arranged on the tank body, a valve III is connected to the air extraction port, and an air extractor is connected to the valve III.

[0009] Optionally, the tank body is connected to a pressure gauge.

[0010] Optionally, the outer wall of the tank body and the outer wall of the material collecting tank are both sleeved with a reinforcing structure in the form of a ring.

[0011] Optionally, the reinforcing structure comprises a plurality of ring-shaped rods distributed in an up-down manner, and a plurality of vertical rods in the form of a ring are fixed between adjacent two ring-shaped rods.

[0012] Optionally, a valve IV is arranged on the upper end of the end portion of the slag discharge pipe connected to the butterfly centrifuge.

[0013] Optionally, the valve I, the valve II, the valve III and the valve IV are electric valves.

[0014] The fermentation liquid centrifugal separation device provided by the application is connected with the material collecting tank through the discharge port of the residue discharge pipe, the lower end of the material collecting tank is connected with the valve I, and the upper part of the material collecting tank is connected with the negative pressure tank capable of generating negative pressure through the valve II, so that after the residue discharge pipe is blocked, the valve I is closed and then the valve II is opened. Since the inside of the negative pressure tank is in a negative pressure state, after the valve II is opened, the negative pressure tank can instantly and quickly suck the gas in the material collecting tank, and the material collecting tank can instantly and quickly suck the residue discharge pipe, so that the mycelium mud blocking the residue discharge pipe is sucked into the material collecting tank, and then compared with the existing manual cleaning mode, only the valve I and the valve II need to be operated to dredge the residue discharge pipe, which is not only convenient to operate, but also the entire cleaning process is completed instantly, the cleaning work can be completed without stopping, and the centrifugal separation efficiency is not affected.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor also belong to the protection scope of the present application.

[0021] As Figs. 1-3 shown:

[0022] The fermentation liquid centrifugal separation device provided by the embodiment of the present application comprises a rack 1, a butterfly centrifuge 2 is installed on the rack 1, and the butterfly centrifuge 2 is connected with a slag discharge pipe 3.

[0023] In the embodiment, the butterfly centrifuge 2 and the mode of the slag discharge pipe 3 and the butterfly centrifuge 2 are all prior art, and will not be described in detail.

[0024] The slag discharge port of the slag discharge pipe 3 is connected with a material collecting tank 6. Specifically, the side end of the material collecting tank 6 is connected with a feeding pipe 7, the feeding pipe 7 is detachably connected with the slag discharge port of the slag discharge pipe 3 through a flange structure. The lower end of the material collecting tank 6 is connected with a valve I 4.

[0025] The upper part of the material collecting tank 6 is connected with a negative pressure tank 8 capable of generating negative pressure through a valve II 5.

[0026] In use, the valve I 4 is opened, the valve II 5 is closed, a certain pressure negative pressure is generated in the negative pressure tank 8, then the butterfly centrifuge 2 performs the centrifugal separation work on the fermentation liquid, the mycelium sludge discharged by the butterfly centrifuge 2 enters the slag discharge pipe 3, and then enters the material collecting tank 6 from the slag discharge pipe 3, and finally is discharged from the valve I 4 and collected through the collecting structure.

[0027] When the slag discharge pipe 3 is blocked, the valve I 4 is closed, and then the valve II 5 is opened. Since the inside of the negative pressure tank 8 is in a negative pressure state, when the valve II 5 is opened, the negative pressure tank 8 rapidly sucks the gas in the material collecting tank 6, and at the same time, the material collecting tank 6 rapidly generates negative pressure, and the material collecting tank 6 rapidly sucks the mycelium sludge blocking the slag discharge pipe 3 into the material collecting tank 6, so as to complete the dredging and cleaning work of the slag discharge pipe 3. After the slag discharge pipe 3 is dredged, the valve II 5 is closed, and the valve I 4 is opened to perform the normal slag discharge work.

[0028] The fermentation liquid centrifugal separation device provided by the embodiment comprises the material collecting tank 6 connected with the slag discharge port of the slag discharge pipe 3, the valve I 4 connected with the lower end of the material collecting tank 6, and the negative pressure tank 8 connected with the upper part of the material collecting tank 6 through the valve II 5, so that when the slag discharge pipe 3 is blocked, the slag discharge pipe 3 can be dredged only by operating and controlling the valve I 4 and the valve II 5.

[0030] In use, after the valve Ⅱ 5 is closed, the valve Ⅲ 82 is opened, and the air extractor 83 is started. The air extractor 83 extracts the gas in the aggregate tank 6, and the gas in the aggregate tank 6 is extracted, so that the negative pressure is generated in the aggregate tank 6. When the negative pressure in the aggregate tank 6 reaches a certain pressure, the valve Ⅲ 82 is closed, and finally the air extractor 83 is closed, so that the aggregate tank 6 is in a negative pressure state.

[0031] In some embodiments of the present application, the tank body 81 is connected with a pressure gauge 9, so as to determine the pressure of the negative pressure in the aggregate tank 6.

At the same time when the negative pressure extracts the deslagging pipe 3, the deslagging pipe 3 can introduce air, so that the other end of the deslagging pipe 3 can introduce air when the negative pressure tank 8 extracts one end of the deslagging pipe 3 through the aggregate tank 6, thereby improving the dredging effect of the deslagging pipe 3.

[0037] In some embodiments of the present application, the valve Ⅰ 4, the valve Ⅱ 5, the valve Ⅲ 82 and the valve Ⅳ 11 are all electric valves.

[0038] In some embodiments of the present application, a switch is further included, and the switch is connected with the valve Ⅰ 4, the valve Ⅱ 5, the valve Ⅲ 82, the valve Ⅳ 11 and the air extractor 83 to form a control circuit.

[0039] The switch is a button switch with an indicating lamp. The button switch comprises a button Ⅰ and a button Ⅱ.
