Description

Technical Field

[0001] This utility model relates to the technical field of oil residue recycling devices, and in particular to an oil residue crushing and collecting device. Background Technology

[0002] In the oil processing industry, a large amount of oil residue is generated after oil is extracted from various oil crops (such as rapeseed, soybeans, and peanuts). Oil residue typically contains a certain proportion of residual oil, protein, and other organic components, possessing high recycling value and can be used as feed, organic fertilizer, or industrial raw materials. In this process, the oil residue crushing and collection device is one of the key pieces of equipment for achieving efficient subsequent utilization of the oil residue; its performance directly affects the efficiency and quality of oil residue treatment.

[0003] In continuous production scenarios, such as large-scale oil processing plants, hundreds of kilograms or even tons of oil residue may be produced per hour. The crushed oil residue needs to be collected and stored promptly. Once the collection bin is full, manual replacement requires stopping the crushing device, moving the full bin to a designated storage area, installing the empty bin in its corresponding position, and restarting the equipment. This series of operations is cumbersome, with each bin replacement typically taking 10 to 30 minutes. During this time, the entire oil residue processing production line is at a standstill. Frequent shutdowns not only significantly reduce production efficiency and increase the time cost per unit of oil residue processing, but also cause additional stress on motors and transmission components due to frequent start-ups and shutdowns, accelerating equipment wear and increasing maintenance frequency and costs. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an oil residue crushing and collection device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an oil residue crushing and collecting device, comprising a collecting mechanism, a grinding mechanism, and a crushing mechanism. The grinding mechanism is bolted to the bottom of the crushing mechanism, and the collecting mechanism is bolted to the bottom of the grinding mechanism. The collecting mechanism consists of a collecting box, a collecting drawer, a collecting trough, a support frame, auxiliary wheels, and a pressure sensor. A through hole is provided on the side surface of the collecting box, and a collecting drawer is installed at the through hole. A collecting trough is provided on the upper surface of the collecting drawer. The collecting trough has a cylindrical trough structure. An auxiliary wheel is fitted to the bottom of the collecting drawer and is mounted on the support frame. A pressure sensor is installed below the support frame and is fixedly connected to the collecting box by bolts.

[0006] By adopting the above technical solution, operators only need to pull out the full drawer and replace it with an empty one while the other is in operation, without waiting for the equipment to stop or carrying the heavy collection box (the pull-out design with auxiliary wheels makes it even easier). This not only reduces the labor intensity of manual labor but also avoids the risk of misoperation that may result from frequent equipment starts and stops. It also reduces the opportunity for operators to come into contact with moving parts of the equipment, improving operational safety and significantly increasing the overall efficiency of oil residue treatment.

[0007] Furthermore, a tripod is welded inside the collection box, and a servo motor is installed on the upper surface of the tripod. The output end of the servo motor is connected to a push plate via a rotating shaft, and the push plate is made of food-grade silicone rubber. A protective cover is installed on the upper surface of the tripod and on the outer side of the servo motor, and the protective cover has an inverted conical structure.

[0008] By adopting the above technical solution, the servo motor drives the push plate to rotate, thereby pushing the oil residue evenly into the collection slot of the collection drawer, avoiding local accumulation, improving the utilization rate of collection space, and the inverted cone-shaped protective cover can prevent oil residue from falling into the servo motor and other components, ensuring stable operation of the equipment.

[0009] Furthermore, the grinding mechanism consists of a grinding box, a grinding roller, a liner, a differential, and a variable frequency motor. The grinding box is bolted to the upper surface of the collecting mechanism, and a liner is installed on the inner side of the grinding box. Grinding teeth are provided on the surface of the liner. The grinding roller is installed inside the grinding box. The grinding mechanism is connected to the differential via a rotating shaft, and a variable frequency motor is connected above the differential.

[0010] By adopting the above technical solution, the grinding roller is driven to rotate by a variable frequency motor and a differential. With the cooperation of the grinding roller and the inner liner, the oil residue is ground and crushed, which enhances the shearing and grinding effect of the oil residue and improves the fineness of the oil residue.

[0011] Furthermore, the crushing mechanism consists of a crushing box, a crushing roller, a first turbine, a second worm gear, and a second turbine. The upper surface of the crushing box has a through-feed inlet. The crushing roller is installed inside the crushing box via a bearing seat. The first turbine is installed on the end surface of the crushing roller. The first turbine and the first worm gear are meshed and connected. The first worm gear is installed on the side surface of the crushing box via a bearing seat. There are two sets of the first worm gear, and the threads of the two sets of the first worm gear have opposite structures. The first worm gear and the second worm gear are fixedly welded. The second worm gear is meshed and connected to the second turbine. The second turbine is installed on the shaft where the grinding roller is located.

[0012] By adopting the above technical solution, the crushing roller achieves synchronous operation of the "crushing-grinding" process through the linkage between the worm gear and the shaft of the grinding roller. No additional power source is needed to drive the crushing mechanism, saving energy. The first worm gear of the two sets of reverse threads drives the crushing roller to rotate relative to each other, enhancing the squeezing and shearing effect on the oil residue, making the initial crushing more thorough and reducing the pressure of subsequent grinding.

[0013] Furthermore, the lower surface of the collection box is bolted with casters, and the casters have a built-in pedal-type locking structure.

[0014] By adopting the above technical solution, the mobility of the crushing and collecting device is greatly improved.

[0015] Furthermore, an integrated controller is mounted on the side surface of the grinding chamber.

[0016] By adopting the above technical solution, the integrated controller on the side surface of the grinding box can centrally control components such as the frequency conversion motor, servo motor, and pressure sensor, realize real-time adjustment of equipment operating parameters (such as crushing speed and grinding frequency), and remind the user to replace the collection box through pressure sensor signal linkage, thereby reducing the intensity of manual operation.

[0017] In summary, this utility model has the following beneficial effects: 1. In this application, the collection drawer can be replaced without stopping the machine, reducing the number of manual steps required for frequent machine start-stop operations. Operators only need to pull out the full drawer and replace it with an empty one while another drawer is in operation, without waiting for the machine to stop or carrying the heavy collection box (the pull-out design with auxiliary wheels makes it even easier). This not only reduces the labor intensity of manual workers but also avoids the risk of misoperation that may result from frequent machine start-stop operations. It also reduces the opportunity for operators to come into contact with moving parts of the equipment, improving operational safety and significantly increasing the overall efficiency of oil residue treatment. 2. In this application, a servo motor is used to drive the push plate to rotate, thereby pushing the oil residue evenly into the collection slot of the collection drawer, avoiding local accumulation, improving the utilization rate of collection space, and the inverted cone-shaped protective cover can prevent oil residue from falling into the servo motor and other components, ensuring stable operation of the equipment.

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] like Figure 1-4 As shown in the figure, this application discloses an oil residue crushing and collecting device, including a collecting mechanism, a grinding mechanism and a crushing mechanism. The grinding mechanism is bolted to the bottom of the crushing mechanism, and the collecting mechanism is bolted to the bottom of the grinding mechanism. The collecting mechanism consists of a collecting box 1, a collecting drawer 4, a collecting trough 5, a support frame 7, an auxiliary wheel 8 and a pressure sensor 9. A through hole is opened through the side surface of the collecting box 1, and a collecting drawer 4 is installed at the through hole. A collecting trough 5 is opened on the upper surface of the collecting drawer 4. The collecting trough 5 has a cylindrical trough structure. An auxiliary wheel 8 is fitted to the bottom of the collecting drawer 4. The auxiliary wheel 8 is installed on the support frame 7. A pressure sensor 9 is installed below the support frame 7. The pressure sensor 9 is fixedly connected to the collecting box 1 by bolts.

[0022] Collection box 1 and collection drawer 4: Collection box 1 is an integral load-bearing structure. The through holes on the side surface form a pull-out sliding fit with collection drawer 4. The cylindrical collection groove 5 on the upper surface of collection drawer 4 directly receives the oil residue after grinding. Its size corresponds to the discharge port of grinding box 2 to ensure that the material falls accurately.

[0023] Auxiliary wheel 8 and support frame 7: The auxiliary wheel 8 is mounted on the support frame 7 by axle pin. The support frame 7 is installed inside the collection box 1. The lower surface of the collection drawer 4 makes rolling contact with the auxiliary wheel 8. This rolling contact converts the sliding friction of the drawer pull-out into rolling friction, making it easier to manually replace the drawer and avoiding machine stoppage caused by the drawer getting stuck.

[0024] Pressure sensor 9: One end of pressure sensor 9 is fixed to the collection box 1 by bolts, and the other end is rigidly connected to the support frame 7. It can directly sense the total weight of the collection drawer 4 and the oil residue inside, and realize the real-time transmission of weight signals.

[0025] The pull-out design of the collection drawer 4 provides the basis for "alternating collection": when one drawer is full, it can be pulled out directly for replacement, and another spare drawer can be inserted into the through hole to continue collecting. With the help of the auxiliary wheel 8, the core requirement of "changing the box without stopping the machine" is achieved. The pressure sensor 9 monitors the weight of the oil residue in real time. When the preset value is reached (such as 80% full), it is transmitted to the integrated controller 24 through an electrical signal to trigger an alarm and avoid overflow.

[0026] The inside of the collection box 1 is welded with a tripod 10. A servo motor 16 is installed on the upper surface of the tripod 10. The output end of the servo motor 16 is connected to a push plate 13 through a rotating shaft. The push plate 13 is made of food-grade silicone rubber. A protective cover 11 is installed on the upper surface of the tripod 10 and on the outer side of the servo motor 16. The protective cover 11 has an inverted conical structure.

[0027] Tripod 10, servo motor 16, and push plate 13: Tripod 10 is welded to the inner wall of collection box 1 (located directly below the discharge port of grinding box 2). Servo motor 16 is fixed to tripod 10 via flange, and its output shaft is connected to push plate 13 via coupling. Push plate 13 is made of food-grade silicone rubber (oil-resistant and flexible). Its length matches the width of collection tank 5, and it can rotate under the drive of servo motor 16. Servo motor 16 drives push plate 13 to reciprocate, evenly dispersing the concentrated falling oil residue in collection tank 5 (avoiding local accumulation), thereby increasing the utilization rate of collection space by more than 30%.

[0028] Protective cover 11: The inverted cone-shaped protective cover 11 is fixed to the tripod 10 by a buckle, completely covering the servo motor 16 and transmission components. Its cone-shaped design can guide the falling oil residue to slide to the collection tank 5, avoiding the accumulation of oil residue on the motor surface. The protective cover 11 ensures that the servo motor 16 is not contaminated by oil residue and extends its service life.

[0029] The grinding mechanism consists of a grinding box 2, a grinding roller 14, a liner 15, a differential 17, and a variable frequency motor 12. The grinding box 2 is bolted to the upper surface of the collecting mechanism, and the liner 15 is installed on the inner side of the grinding box 2. The surface of the liner 15 is provided with grinding teeth. The grinding roller 14 is installed inside the grinding box 2. The grinding mechanism is connected to the differential 17 through a rotating shaft. The variable frequency motor 12 is connected above the differential 17.

[0030] Grinding Mechanism: The grinding box 2 is bolted to the upper surface of the collection box 1, with its bottom outlet facing the working area of ​​the push plate 13 of the collection mechanism to ensure accurate falling of the ground oil residue. The liner 15 is fixed to the inner wall of the grinding box 2 with countersunk bolts, and the grinding teeth on its surface form a meshing gap with the protruding ridges on the surface of the grinding roller 14. The two ends of the grinding roller 14 are mounted on the inner wall of the grinding box 2 through bearing seats, and one end of the shaft extends outside the box and connects to the output end of the differential 17. The differential 17 is fixed to the top of the crushing box 3 by a bracket, and its input end is connected to the variable... The output shaft of the variable frequency motor 12 is connected by a coupling, and the output end is rigidly connected to the shaft of the grinding roller 14. The variable frequency motor 12 (power adapted to the grinding load) is fixed above the differential 17 by bolts to provide a power source. The variable frequency motor 12 drives the grinding roller 14 to rotate through the differential 17. The differential 17 can adjust the speed of the grinding roller 14. Together with the grinding teeth of the inner liner 15, it achieves "extrusion + shearing" dual grinding: after the oil residue enters the grinding box 2, it is carried by the high-speed rotating grinding roller 14 into the space between the grinding teeth and the ridges, and repeatedly crushed to the target particle size.

[0031] The crushing mechanism consists of a crushing box 3, a crushing roller 22, a first turbine 18, a second worm gear 21, and a second turbine 20. The upper surface of the crushing box 3 has a through-feed port 23. The crushing roller 22 is installed inside the crushing box 3 through a bearing seat. The first turbine 18 is installed on the end surface of the crushing roller 22. The first turbine 18 and the first worm gear 19 are meshed and connected. The first worm gear 19 is installed on the side surface of the crushing box 3 through a bearing seat. There are two sets of first worm gear 19. The threads of the two sets of first worm gear 19 have opposite structures. The first worm gear 19 and the second worm gear 21 are fixedly welded. The second worm gear 21 is meshed and connected to the second turbine 20. The second turbine 20 is installed on the shaft where the grinding roller 14 is located.

[0032] Crushing Mechanism: The crushing box 3 is bolted to the upper surface of the grinding box 2, forming a vertical material channel for "crushing-grinding". The crushing roller 22 is horizontally installed inside the crushing box 3 through bearing seats (with dust covers), with the shafts at both ends extending outside the box. The first turbine 18 at the end is connected to the first worm gear 19 by gear meshing. The two sets of first worm gears 19 are arranged in parallel with opposite thread directions (left-hand and right-hand), and are fixed to the same second worm gear 21 by welding. The second worm gear 21 meshes with the second turbine 20, forming a connection of "grinding roller 14 - second turbine 20 - second worm gear 21 - first worm gear 19 - first turbine 18 - crushing roller 22". When the grinding roller 14 rotates, the second turbine 20 drives the second worm gear 21 to rotate, which in turn drives the first worm gear 19 with two sets of opposite threads to rotate synchronously, so that the two crushing rollers 22 rotate in opposite directions. This design eliminates the need for a separate motor for the crushing mechanism, reducing energy consumption by more than 30%, while ensuring the speed matching of the "crushing-grinding" process. The counter-rotating crushing rollers 22 exert a shearing and squeezing effect on the oil residue. The surfaces of the two sets of crushing rollers 22 are provided with staggered crushing teeth. Combined with the relative motion brought by the counter-rotating worm gears, large pieces of oil residue can be initially crushed, reducing the load for subsequent grinding processes and improving overall processing efficiency.

[0033] The lower surface of the collection box 1 is fitted with movable wheels 6 by bolts, and the movable wheels 6 have a pedal-type locking structure.

[0034] Moving wheel 6: The moving wheel 6 is bolted to the lower surface of the collection box 1. The pedal-type locking structure brakes the wheel by pressing the pedal, and the entire device can be moved when unlocked.

[0035] An integrated controller 24 is mounted on the side surface of the grinding chamber 2.

[0036] Integrated controller 24: The integrated controller 24 is installed on the side surface of the grinding box 2 by a snap-fit. The internal circuit is electrically connected to the variable frequency motor 12, the pressure sensor 9, and the servo motor 16 by wires. As the core control unit, the integrated controller 24 can receive the signal from the pressure sensor 9 and synchronously adjust the speed of the variable frequency motor 12. At the same time, it can preset grinding parameters to realize automated grinding control.

[0037] The working principle of the oil residue crushing and collecting device in this embodiment is as follows: oil residue is fed into the crushing box 3 through the feed inlet 23. Under the drive of the grinding roller 14, the crushing roller 22 rotates in the opposite direction to initially crush the oil residue into small particles. After crushing, the material falls into the grinding box 2 through the bottom opening of the crushing box 3. The variable frequency motor 12 drives the grinding roller 14 to rotate through the differential 17. It cooperates with the grinding teeth of the inner liner 15 to further grind the small oil residue particles. After grinding, the material falls from the bottom discharge port of the grinding box 2. The falling oil residue is evenly pushed into the collection slot 5 of the collection drawer 4 by the push plate 13 on the tripod 10. The pressure sensor 9 monitors the weight in real time. When the preset value is reached, the integrated controller 24 issues a reminder. The operator pulls out the full drawer and inserts the empty drawer to achieve continuous collection without stopping the machine.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
