The bottom of the sedimentation tank 1 is a funnel-shaped structure; the stirring mechanism 2 It includes a main shaft 21, a blocking component 22, an extrusion component 23, a stirring component 25 and an oil discharge component 24. The main shaft 21 is located in the center of the sedimentation tank 1 in a vertical state. The main shaft 21 is a hollow shaft structure, and the bottom of the main shaft 21 is provided There are a plurality of feed openings 211 surrounding its axis; the blocking assembly 22 is rotatably arranged inside the collection chamber, and is used to block the feeding openings 211; the extrusion assembly 23 can rotate along the main axis 21 The axial direction of the main shaft 21 is slidably arranged inside the main shaft 21. The extrusion assembly 23 is used to squeeze the oil residue entering the main shaft 21, and the sealing assembly 22 is drivingly connected to the extrusion assembly 23; the oil discharge assembly 24 is located at the feed Above the port 211, the oil drain assembly 24 is connected to the bottom of the main shaft 21; the stirring assembly 25 is rotatably mounted above the oil storage chamber.

First, the raw materials are passed into the heat transfer oil in the sedimentation tank 1, and the raw materials and the heat transfer oil are stirred through the stirring assembly 25, thereby refining animal fat. During the oil refining process, oil residue will be produced, and the oil residue will fall onto the ground through sedimentation. The bottom of the sedimentation tank 1, and the oil residue can flow to the center of the sedimentation tank 1 along the funnel-shaped structure at the bottom of the sedimentation tank 1 under the action of gravity, until the oil residue enters the interior of the main shaft 21 through the feed port 211 of the main shaft 21 , after the oil residue enters the inside of the main shaft 21, the extrusion assembly 23 is started at this time. The extrusion assembly 23 is located at the top of the main shaft 21 in the initial state. The extrusion assembly 23 will slide toward the bottom of the main shaft 21 along the axis direction of the main shaft 21. , thereby squeezing the oil residue at the bottom of the main shaft 21, so that the grease contained in the oil residue can be squeezed out; during the movement of the extrusion component 23, the sealing component 22 connected with it will be driven, causing the sealing The component 22 rotates, and the multiple feed ports 211 on the main shaft 21 are blocked by the rotated blocking component 22, so that the oil residue inside the sedimentation tank 1 cannot continue to enter the inside of the main shaft 21, ensuring that the oil residue is extruded Stability, the grease overflowing during extrusion will flow into the oil drain assembly 24, and the oil drain assembly 24 will drain the overflow grease into the sedimentation tank 1 again, thereby completing the extrusion and collection of oil residue and reducing the workload of workers. Therefore, the equipment can be degreased without having to stop and wait, thereby improving the operating efficiency of the equipment.

As shown in Figures 2 to 8: the blocking assembly 22 includes a rotating drum 221. The rotating drum 221 is rotatably arranged inside the main shaft 21. The bottom of the rotating drum 221 is provided with a notch 2211 that matches the feed port 211. The number of slots 2211 is the same as the number of feed ports 211 and corresponds one to one. There is a gap between two adjacent slots 2211 that can block the feed ports 211 .

By rotating the drum 221, the drum 221 can drive the rotation of the notch 2211. When the notch 2211 is aligned with the feed port 211, the oil residue can enter the interior of the main shaft 21 through the feed port 211, thereby completing the removal of the oil residue. When the slot 2211 rotates to the side of the feed port 211, the feed port 211 is blocked through the gap between the two adjacent slots 2211, thereby blocking the oil residue from continuing to the main shaft 21. The internal flow facilitates the extrusion assembly 23 to squeeze the oil residue inside the main shaft 21, so that the oil residue can be better squeezed, thereby improving the stability of the equipment.

As shown in Figures 2 to 8: the extrusion assembly 23 includes an extrusion block 231, a connecting rod 2312, a screw rod 2321, a first rotation drive motor 2322 and a mounting bracket 232. The mounting bracket 232 is fixedly connected to the top of the sedimentation tank 1. The screw rod 2321 is rotatably arranged under the mounting frame 232 in a vertical state, and the axis of the screw rod 2321 is coaxially arranged with the axis of the sedimentation tank 1. The connecting rod 2312 is sleeved on the screw rod 2321 and matches its thread, extruding The pressing block 231 is fixedly connected to the bottom of the connecting rod 2312. The pressing block 231 is provided with a plurality of slide grooves 2311 surrounding its axis. The rotating drum 221 is provided with limiting bars 2212 that match the slide grooves 2311. The first The rotary drive motor 2322 is located on the mounting bracket 232, and the screw rod 2321 is drivingly connected to the output shaft of the first rotary drive motor 2322.

By starting the first rotary drive motor 2322, the first rotary drive motor 2322 drives the rotation of the screw rod 2321 connected with it. The rotation of the screw rod 2321 drives the movement of the connecting rod 2312 that is threaded with it. Since the bottom of the connecting rod 2312 The extrusion block 231 is fixedly connected, and the extrusion block 231 is provided with a chute 2311, and a limiting bar 2212 is provided in the rotating drum 221, whereby the movement of the connecting rod 2312 drives the movement of the extrusion block 231, so that the extrusion block 231 moves. The block 231 slides along the extension direction of the limiting bar 2212, so that the extrusion block 231 can squeeze the oil residue at the bottom of the main shaft 21 along the direction of the rotating drum 221, thereby completing the extrusion operation of the oil residue and reducing the workload of the staff. burden.

As shown in Figures 2 to 10: the blocking assembly 22 also includes a toothed plate 2213, a driving rod 222, a transmission rod 223, a helical gear 2231, a driving gear 2221 and a synchronous belt 2222. The top of the connecting rod 2312 is provided with an The extended rack 2313 has a semi-circular arc structure, and the axis of the rack 2313 is coaxial with the axis of the connecting rod 2312. The driving rod 222 is horizontally located on the mounting frame 232, and the first gear is sleeved On the driving rod 222, the first gear is meshed with the rack 2313. The transmission rod 223 is located on the side of the driving rod 222, and the axis of the transmission rod 223 and the axis of the driving rod 222 are parallel to each other. The synchronous belt 2222 is sleeved on the driving rod 222. On the rod 222 and the transmission rod 223, the helical gear 2231 is sleeved on the end of the transmission rod 223 away from the mounting bracket 232. The toothed disc 2213 is fixedly connected to the top of the rotating drum 221, and the toothed disc 2213 is meshed with the helical gear 2231.

The rotation of the screw rod 2321 will drive the connecting rod 2312 to move along the limiting bar 2212. The movement of the connecting rod 2312 will drive the movement of its rack 2313. The movement of the rack 2313 will drive the rotation of the driving gear 2221 meshed with it. The rotation of the driving gear 2221 drives the rotation of the driving rod 222 connected thereto. The rotation of the driving rod 222 drives the rotation of the synchronous belt 2222. The rotation of the transmission rod 223 is driven by the synchronous belt 2222. The rotation of the transmission rod 223 drives the rotation of the drive gear 2221. Due to the rotation of the helical gear 2231, the rotation of the helical gear 2231 drives the turntable of the toothed disc 2213 that is meshed with it. The rotation of the toothed disc 2213 drives the rotation of the rotating drum 221 fixedly connected with it, thereby causing the bottom of the rotating drum 221 to rotate. The notch 2211 changes, thereby changing the opening and closing conditions of the feed port 211 on the spindle 21; because the rotation of the drum 221 will drive the movement of its limit bar 2212, the movement of the limit bar 2212 will drive the extrusion The rotation of the pressure block 231 will drive the rotation of the connecting rod 2312 through the squeezing block 231. The rotation of the connecting rod 2312 will change the position of the rack 2313. The teeth of the rack 2313 have a semi-circular arc structure, so that the rack 2313 can follow the rotation of the connecting rod 2313. The rotation of the connecting rod 2312 will not affect its transmission to the driving gear 2221, and thus will not affect the position change of the drum 221, thus improving the stability of the equipment, and it can be used without adding a new driving source. The blocking component 22 is used for control, which can reduce the investment cost of the equipment.

As shown in Figures 2 to 5, 9 and 10: the transmission rod 223 is also provided with a limiting component 224 that limits its position. The limiting component 224 includes a limiting rod 2241 and two limiting blocks 2243. The limit rod 2241 is sleeved on the transmission rod 223. Two limit blocks 2243 are located on both sides of the limit rod 2241. An iron block 2242 is provided on the end of the limit rod 2241 away from the drive rod 222. The two limit blocks 2243 are provided with magnetic blocks 2244 that are magnetically connected to the iron blocks 2242.

During the movement of the extrusion component 23, the blocking component 22 will be driven, causing the rotating drum 221 of the blocking component 22 to rotate. During this process, its transmission rod 223 will rotate, but after the rack 2313 moves away from the driving gear 2221 , since the gear does not have self-locking characteristics, the driving gear 2221 is in the process of free rotation at this time, which will affect the stability of the equipment; through the setting of the limit component 224, the rotation of the transmission rod 223 will drive The limit rod 2241 connected thereto causes the limit rod 2241 to rotate with the transmission rod 223 as the center of the circle until the end of the limit rod 2241 contacts any one of the two limit blocks 2243 on both sides. The iron block 2242 will be adsorbed on the magnetic block 2244, thereby completing the position limitation of the limit rod 2241. Since the limit rod 2241 cannot rotate, the transmission rod 223 cannot continue to rotate, thus ensuring that the blocking assembly 22 will not change after adjustment. When the rack 2313 approaches the driving gear 2221 again, and the driving force of the rack 2313 is greater than the adsorption force between the iron block 2242 and the magnetic block 2244, the driving gear 2221 can drive the driving rod again. 222. The drive rod 222 drives the transmission rod 223, and the transmission rod 223 drives the limit rod 2241, so that the limit rod 2241 can move to the limit block 2243 on the other side, so that the iron block 2242 at its end is in contact with the limit block 2243 on the other side. The limiting block 2243 contacts and is attracted by its magnetic block 2244, thereby improving the stability of the device.

As shown in Figures 2 to 4 and 7: there are multiple oil drain assemblies 24. The number of oil drain assemblies 24 is the same as the number of feed inlets 211 and corresponds one to one. Each oil drain assembly 24 includes a pipe 241, Fixed frame 242 and one-way valve 243. Fixed frame 242 is located between two adjacent feed ports 211. Pipe 241 is sleeved on the fixed frame 242. One end of pipe 241 is connected to the bottom of main shaft 21, and the end Located below the feed port 211 , the one-way valve 243 is sleeved on one end of the pipe 241 close to the main shaft 21 .

After the blocking assembly 22 blocks the feed port 211 , the extrusion assembly 23 will slide toward the bottom of the main shaft 21 along the axis of the main shaft 21 , thereby squeezing the oil residue at the bottom of the main shaft 21 and entering the main shaft 21 The internal grease and the grease overflowing from the grease will flow into the pipe 241 through the connection end of the pipe 241 and the main shaft 21. Through the setting of the one-way valve 243, the grease cannot return to the main shaft 21 after entering the pipe 241, so that the oil residue in the pipe 241 will not return to the main shaft 21. The grease can be squeezed dry, and the grease entering the pipeline 241 will be discharged into the sedimentation tank 1 through the outlet at the other end, and will be stirred and sedimented again in the sedimentation tank 1.

As shown in Figures 2 to 4, Figures 7 and 8: both ends of the main shaft 21 are provided with openings 212. The bottom of the main shaft 21 passes through the bottom of the sedimentation tank 1 and extends to one end of the bottom of the sedimentation tank 1. The main shaft 21 has an opening 212 at both ends. The opening 212 at the bottom is provided with a cover plate 213 that is threadedly matched with the cover plate 213 . A support column 2131 extending along the axial direction of the main shaft 21 is provided in the center of the cover plate 213 .

Through the arrangement of the opening 212 and the cover plate 213, after the squeezing assembly 23 squeezes out the oil residue, the cover plate 213 can be rotated to remove it from the opening 212 at the bottom of the main shaft 21, thereby facilitating the squeezing of the main shaft 21. The final oil residue is collected and cleaned so that the grease will not enter the sedimentation tank 1 again, so that the equipment does not need to be shut down to clean the oil residue in the sedimentation tank 1, improving the operating efficiency of the equipment and reducing the burden on the staff. Since part of the main shaft 21 extends to the bottom of the sedimentation tank 1, there is an end distance between the bottom of the main shaft 21 and the port connecting the pipe 241 and the main shaft 21. If there is no support column 2131, the extrusion assembly 23 directly squeezes the oil residue, so that Grease cannot flow into the pipe 241 of the oil drain assembly 24, which affects the squeezing operation of the oil residue. Through the setting of the support column 2131, the bottom of the main shaft 21 can be raised, so that the bottom of the main shaft 21 is connected to the pipe 241 and the main shaft 21. There is a minimum distance between the ports so that the grease can be easily discharged when the oil residue is squeezed.

As shown in FIG. 7 , a guide groove 2111 extending along the radial direction of the main shaft 21 is provided on the outside of each feed port 211 . The guide groove 2111 has a trumpet-shaped structure.

Through the arrangement of the trumpet-shaped guide groove 2111, the oil residue at the bottom of the sedimentation tank 1 can be better guided to facilitate the flow into the interior of the main shaft 21 and improve the collection effect and efficiency of the oil residue.

As shown in Figures 1 to 6: the stirring assembly 25 includes a plurality of rotating rings 251. The multiple rotating rings 251 are sleeved on the main shaft 21. Each rotating ring 251 is provided with a plurality of stirring rods surrounding its axis. 2511, a fixed rod 2512 is provided between two adjacent stirring rods 2511.

Through the arrangement of the rotating ring 251 and the stirring rod 2511, the rotation of the rotating ring 251 can drive the rotation of the stirring rod 2511, thereby stirring the grease in the sedimentation tank 1 and improving the efficiency of oil refining. Through the setting of the fixed rod 2512, it can The stirring rods 2511 between the plurality of rotating rings 251 are fixed together, thereby improving the structural strength of the entire device. At the same time, one of the rotating rings 251 is driven to rotate, and the remaining rotating rings 251 can rotate.

As shown in Figures 1 to 6: the stirring assembly 25 also includes a ring gear 252, a pinion gear 2531, a second rotation drive motor 253 and a connecting frame 2521.

The second rotary drive motor 253 is located above the pinion gear 2531, and the pinion gear 2531 is transmission connected with the second rotary drive motor 253. The connecting frame 2521 is fixed. Connected to the ring gear 252 , the connecting frame 2521 is fixedly connected to the rotating ring 251 near the top of the main shaft 21 among the plurality of rotating rings 251 .

Step 1: Based on the detection values of the rotation speed sensor one and the rotation speed sensor two, calculate the resistance of the grease received by the stirring rod 2511 in the stirring assembly 25 during stirring through formula (1):

(1);

Among them, F is the resistance of the grease received by the stirring rod 2511 in the stirring assembly 25 during stirring, is the contact surface area between stirring rod 2511 and grease,/> is the detection value of speed sensor one,/> is the detection value of speed sensor one,/> is pi,/> Take 3.14,/> is the radius of the output shaft of the second rotary drive motor 253,/> is the radius of main axis 21,/> is the thickness of stirring rod 2511,/> The preset dynamic viscosity of grease at normal temperature,/> is the preset viscosity index of grease,/> is the friction coefficient between stirring rod 2511 and grease;

Step 2: Based on the timer and the calculation result of formula (1), the controller calculates the service life of the stirring rod 2511 in the stirring assembly 25 through formula (2):

(2);

in, For the service life of the mixing component 25,/> is the stress correction coefficient of stirring rod 2511,/> is the tensile strength of stirring rod 2511,/> is the detection value of the timer,/> is unit time;/> is the Poisson's ratio of the stirring blade material;

Step 3: The controller compares the service life of the stirring rod 2511 in the mixing component 25 with the preset service life. When the service life of the stirring rod 2511 in the mixing component 25 is less than the preset service life (0.8), the controller controls The alarm sounds an alarm prompt.

in, It means that when the stirring rod 2511 is driven by the second rotary drive motor 253 and stirs the grease, the friction coefficient between the stirring rod 2511 and the grease is affected by the material properties of the grease. During the entire stirring process, The resistance of the grease to the area of stirring rod 2511, Indicates that the resistance of the grease encountered by the stirring rod 2511 during stirring is corrected for the influence of the stirring rod 2511 during long-term use based on its own material size factors and its own tensile strength - thus obtaining the mixing component 25 For the service life, the rotation speed sensor 1 and rotation speed sensor 2 are used to detect the differential speed of the stirring rod 2511. The controller uses formula 1 to calculate the resistance of the grease in the mixing component 25 when the mixing rod 2511 is stirring and formula 2 to calculate the mixing component. 25 service life, when the service life of the stirring rod 2511 in the mixing assembly 25 is less than the preset service life (0.8), the controller controls the alarm to issue an alarm prompt to remind the operator of the mixing rod 2511 in the mixing assembly 25 Breakage may occur and the operator needs to stop the second rotary drive motor 253 and stop injecting grease, improving the safety and reliability of the device.
