[0023] Example 1: Please refer to Figure 1-Figure 4 , Figure 7 , Figure 8 and Fig.11 As shown, the present invention provides a technical solution: a disc centrifuge specially used for high-concentration fermentation liquid, comprising a centrifuge body 1, and an auxiliary mechanism 2 is arranged on one side of the centrifuge body 1; The auxiliary mechanism 2 includes a processing box 201, a box cover 202 is installed on the top of the processing box 201, and two connecting pipes 203 are fixedly penetrated on the upper side of the box cover 202, and the liquid inlet ends of the two connecting pipes 203 are installed with electric regulating valves 204, and the liquid inlet ends of the two electric regulating valves 204 are installed with liquid storage shells 205, and the top openings of the two liquid storage shells 205 are provided with sealing plugs 206, and a cam rotor pump 207 is installed on the upper side of the box cover 202, and the liquid inlet end of the cam rotor pump 207 is installed with a liquid inlet pipe 208, and the liquid outlet end of the cam rotor pump 207 is installed with a three-way pipe 209, and the two liquid outlet ends of the three-way pipe 209 are installed with electric ball valves 210, and the liquid outlet end of one of the electric ball valves 210 is installed with a first delivery pipe 211, and the liquid outlet end of the first delivery pipe 211 is installed with a single-port pipe 212, and a plurality of cylindrical holes 213 are opened in the single-port pipe 212, and the liquid inlet end of the box cover 202 A circular plate 214 is installed, a sensor 215 is installed inside a through hole on one side of the processing box 201, a second delivery pipe 216 is installed at the liquid outlet end of another electric ball valve 210, the liquid inlet end of the liquid inlet pipe 208 movably passes through the upper side of the box cover 202, the inlet end of the liquid inlet pipe 208 is close to the bottom of the inner wall of the processing box 201, the liquid inlet end of the single-port tube 212 is fixedly passed through the bottom of the box cover 202, each cylindrical hole 213 is located close to the bottom of the inner wall of the processing box 201, the detection end of the sensor 215 extends to the interior of the processing box 201, the centrifuge body 1 includes a box body 101, one side of the box body 101 is fixed to the surface of the processing box 201, the liquid outlet end of the second delivery pipe 216 is connected to the feed end of the feed pipe 111, the two electric regulating valves 204, the cam rotor pump 207, the two electric ball valves 210 and the sensor 215 are all electrically connected to the controller 126.

[0024] In this embodiment, when it is necessary to process the high-concentration fermentation liquid, the circular plate 214 is first removed from the box cover 202, and then the liquid outlet end of the hose for transporting the high-concentration fermentation liquid to be processed is connected to the liquid inlet end of the box cover 202, and then a proper amount of high-concentration fermentation liquid is injected into the processing box 201 through the cooperation of the hose and the box cover 202. When the processing box 201 is injected with a proper amount of high-concentration fermentation liquid, the hose is directly stopped from transporting the high-concentration fermentation liquid to the liquid inlet end of the box cover 202, and then the controller 126 is used to open the sensor 215 (pH sensor). At this time, the detection end of the opened sensor 215 will immediately detect the pH value of the high-concentration fermentation liquid in contact with it, and directly transmit the detected pH value data in the form of electrical signals. The pH value is transmitted to the controller 126 in a certain manner, and then the controller 126 compares the received pH value with the pH value threshold value set in advance by the controller 126. When the pH value received by the controller 126 is higher than the pH value threshold value set in advance by the controller 126, it indicates that the high-concentration fermentation liquid is too alkaline. At this time, the controller 126 opens the corresponding electric regulating valve 204, the cam rotor pump 207 and one of the electric ball valves 210. At this time, the adjusting agent (used to neutralize the alkaline fermentation liquid) in the corresponding liquid storage shell 205 is directly guided to the inside of the treatment box 201 through the cooperation of the opened electric regulating valve 204 and the corresponding connecting pipe 203. When a small amount of adjusting agent is injected into the inside of the treatment box 201, the controller 126 directly closes the opened electric regulating valve 204. The regulating valve 204, at the same time, the started cam rotor pump 207 will extract the mixed liquid composed of the high-concentration fermentation liquid and the adjusting agent in the treatment box 201 through the cooperation of the liquid inlet pipe 208 connected thereto, and then transport it to the inside of the three-way pipe 209, and then through the cooperation of the opened electric ball valve 210, the first delivery pipe 211, the single-port pipe 212 and the plurality of cylindrical holes 213, it is directly transported back to the inside of the treatment box 201, that is, the mixed liquid transported back to the inside of the treatment box 201 is used to stir the mixed liquid in the treatment box 201, so as to promote the high-concentration fermentation liquid and the adjusting agent to be fully mixed together. When the pH value received by the controller 126 is within the pH value threshold range set by the controller 126 in advance, the controller 126 will completely Close the corresponding electric regulating valve 204 (in the process of adjusting the fermentation liquid, the electric regulating valve 204 is opened intermittently, that is, to facilitate the adjustment agent in the corresponding liquid storage shell 205 to be transported to the processing box 201), and at the same time close the sensor 215, then the controller 126 will close one of the electric ball valves 210 and open the other electric ball valve 210. At this time, the treated high-concentration fermentation liquid entering the three-way pipe 209 will be directly transported to the inside of the second delivery pipe 216, and then transported to the inside of the feed pipe 111. When the pH value received by the controller 126 is lower than the pH value threshold value set by the controller 126 in advance, it means that the fermentation liquid is too acidic. At this time, the controller 126 will fully follow the above operation steps to open the corresponding electric regulating valve 204.The regulator in the corresponding liquid storage shell 205 is transported to the processing box 201 through the cooperation of the opened electric regulating valve 204 and the corresponding connecting pipe 203, and is fully mixed with the high-concentration fermentation liquid until the pH value of the fermentation liquid is within the pH value threshold range pre-set by the controller 126, and then transported to the inside of the feed pipe 111. At this time, the high-concentration fermentation liquid transported to the inside of the feed pipe 111 has a reduced corrosive effect on the entire disc centrifuge, and can also keep the physical properties of the substances in the high-concentration fermentation liquid stable, that is, to ensure that the disc centrifuge has a good separation effect in the later stage, and the risk of clogging is reduced.

[0027] The effect and working principle of the whole mechanism are as follows: when it is necessary to process the high-concentration fermentation liquid, the controller 126 is first connected to the external power supply through the prepared power line, and then the liquid inlet end of one of the L-shaped tubes 125 is connected to the water outlet end of the pipe for conveying water (the water inlet end of the pipe is connected to the water pump, and the water inlet end of the water pump is connected to the water outlet end of the water tank), and then the liquid outlet end of the other L-shaped tube 125 is connected to the water inlet end of the pipe for draining water (the water outlet end of the pipe is connected to the water inlet end of the water tank), and then the liquid outlet end of the first electric valve 122 is connected to the water inlet end of the prepared infusion pipe (for conveying the treated high-concentration fermentation liquid), and then the two tank covers 202 are respectively removed from the corresponding liquid storage shells 205. Remove it, and then inject appropriate amounts of adjusting agents (one part for neutralizing the acidic fermentation liquid and one part for neutralizing the alkaline fermentation liquid) into the two liquid storage shells 205 respectively. Finally, place a prepared collection bucket under the guide tube 120, and turn on the controller 126 at the same time, set the opening and closing time of one of the second electric valves 124, the opening and closing time of the other second electric valve 124, the pH value threshold of the fermentation liquid (a neutral value) and the valve opening and closing degree of the two electric regulating valves 204. When everything is ready, first remove the circular plate 214 from the box cover 202, and then connect the liquid outlet end of the hose that transports the high-concentration fermentation liquid to be treated to the liquid inlet end of the box cover 202, and then, through the cooperation of the hose and the box cover 202, to the treatment box 2 01 is injected with an appropriate amount of high-concentration fermentation liquid. When the processing box 201 is injected with an appropriate amount of high-concentration fermentation liquid, the hose is directly stopped from transporting the high-concentration fermentation liquid to the liquid inlet end of the box cover 202, and then the sensor 215 (pH sensor) is opened by the controller 126. At this time, the detection end of the opened sensor 215 will immediately detect the pH value of the high-concentration fermentation liquid in contact with it, and directly transmit the detected pH value data to the controller 126 in the form of an electrical signal. Then, the controller 126 will compare the received pH value with the pH value threshold value set by the controller 126 in advance. When the pH value received by the controller 126 is higher than the pH value threshold value set by the controller 126 in advance, it means that the high-concentration fermentation liquid is too high. The liquid is too alkaline, and the controller 126 will open the corresponding electric regulating valve 204, the cam rotor pump 207 and one of the electric ball valves 210. At this time, the adjusting agent (used to neutralize the alkaline fermentation liquid) in the corresponding liquid storage shell 205 will be directly guided to the inside of the treatment box 201 through the cooperation of the opened electric regulating valve 204 and the corresponding connecting pipe 203. When a small amount of adjusting agent is injected into the inside of the treatment box 201, the controller 126 will directly close the opened electric regulating valve 204. At the same time, the started cam rotor pump 207 will extract the mixed liquid composed of high-concentration fermentation liquid and adjusting agent in the treatment box 201 through the cooperation of the liquid inlet pipe 208 connected thereto, and then transport it to the inside of the three-way pipe 209.Then, through the cooperation of the opened electric ball valve 210, the first delivery pipe 211, the single-port pipe 212 and the plurality of cylindrical holes 213, it is directly transported back to the interior of the processing box 201, that is, the mixed liquid transported back to the interior of the processing box 201 is used to stir the mixed liquid inside the processing box 201, thereby promoting the high-concentration fermentation liquid and the adjusting agent to be fully mixed together. When the pH value received by the controller 126 is within the pH value threshold range pre-set by the controller 126, the controller 126 will completely close the corresponding electric regulating valve 204 (during the fermentation liquid adjustment process, the electric regulating valve 204 is intermittently opened, that is, to facilitate the adjusting agent in the corresponding liquid storage shell 205 to be transported to the processing box 201), and at the same time close the sensor 215, and then The controller 126 will close one of the electric ball valves 210 and open the other electric ball valve 210. At this time, the treated high-concentration fermentation liquid entering the three-way pipe 209 will be directly transported to the inside of the second transport pipe 216, and then transported to the inside of the feed pipe 111. When the pH value received by the controller 126 is lower than the pH value threshold value set in advance by the controller 126, it means that the fermentation liquid is too acidic. At this time, the controller 126 will fully perform the above operation steps, open the corresponding electric regulating valve 204, and allow the regulator in the corresponding liquid storage shell 205 to be transported to the processing box 201 through the cooperation of the opened electric regulating valve 204 and the corresponding connecting pipe 203, and fully mixed with the high-concentration fermentation liquid until the pH value of the fermentation liquid is lower than the pH value threshold value set in advance by the controller 126. When the pH value is within the pH value threshold range set in advance by the controller 126, the fermentation liquid is then transported to the inside of the feed pipe 111. At this time, the high-concentration fermentation liquid transported to the inside of the feed pipe 111 reduces the corrosion effect on the entire disc centrifuge, and at the same time, the physical properties of the substances in the high-concentration fermentation liquid can be kept stable, that is, a good separation effect is ensured in the later stage, and the risk of blockage is reduced. When the high-concentration fermentation liquid with the adjusted pH value is transported to the inside of the feed pipe 111, the controller 126 is used to immediately open one of the second electric valves 124, and then one of the L-shaped pipes 125, the water transport pipe, the opened one of the second electric valves 124 and the corresponding water pipe 123 are used to move the movable shell 10 8 and the housing 102. When water is continuously injected into the gap between the contact surfaces of the housing 108 and the housing 102, the movable housing 108 will move upward. When the top of the movable housing 108 contacts the bottom of the drum 128, and the bottom of the inner wall of the movable housing 108 contacts the bottom of the guide housing 109, the controller 126 will close one of the second electric valves 124, and then the controller 126 will turn on the motor 103. At this time, the controller 126 will drive the rotating rod 105 connected thereto to rotate under the cooperation of the housing 101, the first bearing and the mounting hole 104. Then, the rotating rotating rod 105 will drive the rotating shaft 106 to rotate under the cooperation of the two meshing bevel gears 107, the second bearing, the housing 101 and the housing 102.The rotating shaft 106 rotates at the same time, and the plurality of discs 114 and two sealing rings 115 rotate at the same time under the cooperation of the diverter cone 110, the guide column 129, the drum 128, the mounting column 112 and the sleeve 113. At this time, the processed fermentation liquid entering the feed pipe 111 will be diverted to the diverter cone 110, and then the fermentation liquid contacting the diverter cone 110 will be evenly distributed under the cooperation of the diverter cone 110, the two sealing rings 115, the guide column 129, the guide shell 109, the movable shell 108, the mounting column 112, the drum 128, the limit ring 116 and the fixed ring 117. The fermentation liquid flows into the interior of the housing 102, and then the housing 102, the drum 128, the plurality of rotating discs 114, the rotating sleeve 113 and the rotating mounting column 112 cooperate to separate the solid particles and the liquid in the fermentation liquid, and the separated solids are left at the angle formed by the movable housing 108 and the drum 128. Then, the clean fermentation liquid is transported to the liquid outlet of the drum 128, and finally transported away through the cooperation of the opened first electric valve 122, the liquid outlet pipe 118 and the liquid infusion pipe connected to the first electric valve 122. When one of the second electric valves 122 is opened, the liquid outlet pipe 118 is opened, and the liquid infusion pipe connected to the first electric valve 122 is opened. When the closing time of valve 124 is reached and the opening time of the other second electric valve 124 is reached, the controller 126 will close one of the second electric valves 124 and open the other second electric valve 124. At this time, the water in the gap between the contact surface of the movable shell 108 and the housing 102 is transported away through the cooperation of the opened other second electric valve 124, the corresponding water pipe 123, the other L-shaped pipe 125 and the pipe ready for drainage. When the water in the above gap is drained away, the solid particles in the above angle will be discharged into the discharge pipe 119, and then It is transported to the inside of the guide tube 120 and then to the prepared collection bucket. When the accumulated solid particles at the angle are discharged, the start time of one of the second electric valves 124 is just reached, and the closing time of the other second electric valve 124 is just reached. At this time, the controller 126 will close the other second electric valve 124 and open one of the second electric valves 124. At this time, water will be injected into the gap again until the top of the movable shell 108 and the bottom of the drum 128 are in contact. This reciprocating process can realize the solid-liquid two-phase separation operation of the high-concentration fermentation liquid.
