Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifugal dehydrator technology, and more specifically, to an automatic single-barrel centrifugal dehydrator. Background Technology
[0002] Centrifuges are instruments that use the centrifugal force generated by rotating rotors to separate substances of different densities and particle sizes in suspensions or emulsions, or to analyze them simultaneously during separation. They have a wide range of applications, including chemical, food, pharmaceutical, environmental protection, and mining industries. Vegetables naturally contain moisture after washing, and if the moisture is not removed for a long time, it may cause the vegetables to rot. In this case, a vegetable centrifuge is needed to remove the moisture from the vegetables.
[0003] Existing vegetable centrifuges require manual placement of washed vegetables into the centrifuge tank during operation, and manual removal of the centrifuged vegetables after centrifugation, resulting in a low degree of automation.
[0004] In addition, during the centrifugation process, the vegetables rotate along with the centrifuge, causing them to come into close contact with the filter holes on the inner wall of the centrifuge when they rotate at high speed. This results in vegetable debris clogging the filter holes, making it impossible to effectively remove the moisture from the vegetables when they are reused, thus preventing the vegetables from being efficiently dried.
[0005] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content
[0006] The purpose of this invention is to provide an automatic single-barrel centrifugal dehydrator that requires no manual intervention, thereby improving the degree of automation and work efficiency.
[0007] This utility model provides an automatic single-drum centrifugal dewatering machine, including a frame, a motor, a dewatering drum, a feeding and conveying device, and a light detection sensor. The motor is fixed at the upper end of the frame, and the output shaft of the motor forms a 45-degree angle with the horizontal plane. The dewatering drum includes a connecting shaft, support rods, and a sleeve. Three support rods are connected to the side of the connecting shaft, and the included angle between adjacent support rods is 120 degrees. The other end of each support rod is connected to the inner wall of the sleeve. The connecting shaft is connected to the output shaft of the motor. The side of the sleeve is provided with dense drainage holes, and an outlet slope is provided at the opening of the sleeve away from the motor. The feeding and conveying device is connected to the upper end of the frame, and the feeding and conveying device is parallel to the horizontal plane. The outlet end of the feeding and conveying device is located directly above the inlet end of the sleeve. The light detection sensor is also fixed at the upper end of the frame, and the detection end of the light detection sensor points into the sleeve.
[0008] Using the above technical solution, the motor is first turned on and the sleeve is slowly rotated. Then, the washed vegetables are placed directly on the feeding and conveying device. Driven by the conveyor belt, the vegetables fall into the sleeve from directly above the inlet end. The vegetables will accumulate at the bottom of the sleeve. When the light detection sensor detects that the height of the vegetables in the sleeve meets the requirements, the feeding and conveying device will stop conveying the vegetables. At the same time, the motor will be controlled to rotate at high speed for centrifugal dehydration. After centrifugal dehydration, the motor speed gradually decreases, and the vegetables inside the sleeve will be thrown out along the outlet slope due to inertia.
[0009] Furthermore, the automatic single-barrel centrifugal dewatering machine also includes a blower and a blower pipe. One end of the blower pipe is fixed to the upper end of the frame, the outlet of the blower pipe points to the inner wall of the sleeve, and the other end of the blower pipe is connected to the air outlet of the blower.
[0010] Using the above technical solution, when the blower is turned on, the airflow will blow into the sleeve through the blower pipe, thereby blowing out the vegetable scraps blocked on the drain hole from the inclined surface of the outlet.
[0011] Furthermore, a waterproof cover is connected to the front of the frame, and the waterproof cover is placed over the dewatering roller.
[0012] Furthermore, a diversion plate is provided below the dewatering drum, and the diversion plate is fixed on the frame.
[0013] The automatic single-barrel centrifugal dehydrator provided by this utility model first turns on the motor, causing the sleeve to rotate slowly. Then, the washed vegetables are placed directly on the feeding conveyor. Driven by the conveyor belt, the vegetables fall into the sleeve from directly above the inlet end. The vegetables accumulate at the bottom of the sleeve. When the light detection sensor detects that the height of the vegetables in the sleeve meets the requirements, it controls the feeding conveyor to stop conveying vegetables and simultaneously controls the motor to rotate at high speed for centrifugal dehydration. After centrifugal dehydration, the motor speed gradually decreases, and the vegetables inside the sleeve are thrown out along the outlet slope due to inertia. The design of the motor output shaft at a 45-degree angle to the horizontal plane allows the vegetables to be thrown out along the outlet slope by their own inertia as the motor speed gradually decreases, without manual intervention, thus improving the degree of automation and work efficiency.

Figure 6 for Figure 1 A structural schematic diagram of the dewatering drum of an automatic single-drum centrifugal dewatering machine from another perspective. Please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The automatic single-drum centrifugal dewatering machine provided in this embodiment includes a frame 1, a motor 2, a dewatering drum 3, a feeding and conveying device 4, and a light detection sensor 5. The motor 2 is fixed at the upper end of the frame 1, and the output shaft of the motor 2 forms a 45-degree angle with the horizontal plane. The dewatering drum 3 includes a connecting shaft 31, support rods 32, and a sleeve 33. Three support rods 32 are connected to the side of the connecting shaft 31, and the included angle between adjacent support rods 32 is 120 degrees. The other end of the support rod 32 is connected to the inner wall of the sleeve 33. The connecting shaft 31 is connected to the output shaft of the motor 2; the sleeve 33 has dense drainage holes 34 on its side, and an outlet slope 35 is provided at the opening of the sleeve 33 away from the motor 2; the feeding and conveying device 4 is connected to the upper end of the frame 1, the feeding and conveying device 4 is parallel to the horizontal plane, and the outlet end of the feeding and conveying device 4 is located directly above the inlet end of the sleeve 33; the light detection sensor 5 is also fixed at the upper end of the frame 1, and the detection end of the light detection sensor 5 points into the sleeve 33.
[0030] It should be noted that in this utility model of automatic single-barrel centrifugal dehydrator, motor 2 is a three-phase asynchronous motor. In use, motor 2 is first turned on and drives the sleeve 33 to rotate slowly. Then, the washed vegetables are placed directly on the feeding conveyor 4. Driven by the conveyor belt, the vegetables fall into the sleeve 33 from directly above the inlet end. The vegetables will accumulate at the bottom of the sleeve 33. When the light detection sensor 5 detects that the height of the vegetables in the sleeve 33 meets the requirements, it will control the feeding conveyor 4 to stop conveying vegetables and control motor 2 to rotate at high speed for centrifugal dehydration. After centrifugal dehydration, the speed of motor 2 gradually decreases, and the vegetables inside the sleeve 33 will be thrown out along the outlet slope 35 due to inertia.
[0031] The automatic single-barrel centrifugal dehydrator of this utility model has a 45-degree angle between the output shaft of motor 2 and the horizontal plane. As the speed of motor 2 gradually decreases, vegetables can be thrown out along the outlet slope 35 by their own inertia without manual intervention, which improves the degree of automation and work efficiency.

One end of the blower pipe 7 is fixed to the upper end of the frame 1, the pipe opening of the blower pipe 7 points to the inner wall of the sleeve 33, and the other end of the blower pipe 7 is connected to the air outlet of the blower 6.
[0033] It should be noted that when the blower 6 is turned on, the airflow will be blown into the sleeve 33 through the blower pipe 7, which can blow out the vegetable scraps blocked on the drain hole 34 through the outlet slope 35. When used again, the drain hole 34 can efficiently spin dry and remove the moisture from the vegetables.
[0034] Further reference Figure 1 , Figure 4 The present invention has a waterproof cover 8 connected to the front of the frame 1, the waterproof cover 8 covering the dewatering drum 3; a diversion plate 9 is provided below the dewatering drum 3, the diversion plate 9 being fixed to the frame 1.
[0035] As can be seen from the above description, the advantages of this utility model are:
[0036] This utility model discloses an automatic single-barrel centrifugal dehydrator. In operation, the motor is first turned on, causing the sleeve to rotate slowly. Then, the washed vegetables are placed directly on the feeding conveyor. Driven by the conveyor belt, the vegetables fall into the sleeve from directly above the inlet end. The vegetables accumulate at the bottom of the sleeve. When the light detection sensor detects that the vegetable accumulation height inside the sleeve meets the requirements, the feeding conveyor stops conveying the vegetables, and simultaneously controls the motor to rotate at high speed for centrifugal dehydration. After centrifugal dehydration, the motor speed gradually decreases, and the vegetables inside the sleeve are thrown out along the outlet slope due to inertia. The 45-degree angle between the motor's output shaft and the horizontal plane allows the vegetables to be thrown out along the outlet slope by their own inertia as the motor speed gradually decreases, eliminating the need for manual intervention and improving automation and work efficiency.
