Abstract
Description
Technical Field
[0001] This utility model belongs to the field of industrial dewatering machine technology, specifically, it relates to a high-speed centrifugal dewatering screen. Background Technology
[0002] A centrifugal dewatering screen is a mechanical device that uses centrifugal force to separate liquids and solids (or liquids of different densities). Its core function can be summarized as: using the powerful centrifugal force generated by high-speed rotation to quickly and efficiently remove moisture or liquid from materials. It is used in industrial applications for dewatering sand, gravel, and metal slag.
[0003] The most common horizontal screw discharge sedimentation centrifuge works by using a screw conveyor inside the drum to continuously push the solid particles (filter cake) deposited on the inner wall of the drum toward the discharge end (small end) of the drum. However, because of this, there is a speed difference between the screw and the drum. The screw conveyor usually rotates slightly slower than the drum. Therefore, while achieving continuous pushing and discharge of solids, the equipment also generates a lot of noise, which can cause some inconvenience to factory workers.
[0004] In view of this, the applicant proposes a new technical solution based on the existing technology, which effectively combines the screw conveyor with the drum, and uses a coaxial fan to generate airflow so that solid particles can be effectively discharged from the equipment. Utility Model Content
[0005] The main purpose of this invention is to provide a high-speed centrifugal dewatering screen, which aims to reduce equipment noise and improve drying effect.
[0006] This utility model discloses a high-speed centrifugal dewatering screen, comprising:
[0007] The base has a cover plate on top and a feeder at the end, and a power unit is installed inside the base;
[0008] A centrifugal dewatering component is horizontally arranged between the base and the cover plate and is connected to the power device for transmission.
[0009] A coaxial fan is provided, with its tail end coaxially connected to the centrifugal dehydration component, and the coaxial fan is adapted to guide airflow into the centrifugal dehydration component.
[0010] The feeder connects to the centrifugal dewatering component through the power unit and injects material into the centrifugal dewatering component. The centrifugal dewatering component generates centrifugal force to separate the water from the material and discharge it through the base.
[0011] Furthermore, the centrifugal dehydration component includes:
[0012] A centrifuge cylinder has spiral blades on its inner wall and a filter screen on its outer side, and the surface of the centrifuge cylinder has several through holes.
[0013] A magnetic coupling has several permanent magnets arranged circumferentially at its ends, and a shaft tube is arranged at the center of the magnetic coupling.
[0014] Furthermore, the power unit includes:
[0015] A magnetic turntable has paired magnets arranged circumferentially, and the paired magnets are magnetically connected to the permanent magnet.
[0016] A transmission wheel is coaxially connected to the magnetic turntable, and a central hole is provided at the center of the magnetic turntable, which passes through the transmission wheel and is sleeved on the shaft tube.
[0017] The motor's output shaft is connected to the transmission wheel via a transmission belt.
[0018] Furthermore, the base includes a base body, a water collection tank, a drain outlet, a discharge outlet, and a fan slot. The fan slot is located at the end of the base body. The water collection tank is provided inside the base body. The drain outlet is provided at the bottom of the water collection tank. The discharge outlet is provided between the water collection tank and the fan slot.
[0019] The centrifugal dewatering component is installed in the water collection tank, and the material dewatered by the centrifugal dewatering component is discharged from the discharge port.
[0020] Furthermore, the feeder includes a feed trough, a conical funnel, and a feed pipe. The feed trough is cubic, and a conical funnel is provided at the top of the feed trough. The bottom of the conical funnel is connected to the feed pipe, and the feed pipe is connected to the shaft pipe.
[0021] Furthermore, the cover plate is equipped with a heating wire for heating the water collection tank.
[0022] Furthermore, the coaxial fan includes a fan, a connecting shaft, and a cover, wherein the end of the centrifuge cylinder is coaxially and fixedly connected to the cover, the cover is connected to one end of the connecting shaft, and the other end of the connecting shaft is connected to the fan.
[0023] The technical solution disclosed in this utility model mainly uses the high-speed rotation of the centrifugal dehydration component to generate a centrifugal force field, which separates the fluid substance from the solid material. At the same time, the centrifugal dehydration component drives the fan to rotate, generating an airflow that blows towards the centrifugal dehydration component. The airflow forms turbulence within the centrifugal dehydration component, which disperses the dried material. Since the spiral blades inside the centrifugal dehydration component are fixedly connected to the centrifuge cylinder and there is no relative motion between the two, the noise generated by friction can be effectively reduced, and the material drying effect can be further improved.

[0042] Please refer to this as well. Figures 1-8This utility model discloses a high-speed centrifugal dewatering screen for dewatering sand, gravel, and metal slag. The main structure of the equipment includes a base 1, a centrifugal dewatering component 5, and a coaxial fan 4. A cover plate 3 is installed on the top of the base 1, and a feeder 2 is installed at the end of the base 1 for adding materials containing water. A power unit 6 is installed inside the base 1 to drive the centrifugal dewatering component 5 to rotate, thereby forming a centrifugal force field. The centrifugal dewatering component 5 is horizontally positioned between the base 1 and the cover plate 3. The cover plate 3 prevents water droplets from splashing. The end of the centrifugal dewatering component 5 is connected to the power unit 6, thereby driving the centrifugal dewatering component 5 to rotate. The coaxial fan 4 rotates and is adapted to blow airflow into the centrifugal dewatering component 5. The airflow forms turbulence within the centrifugal dewatering component 5, breaking up the raw materials adhering to the inner wall of the centrifugal dewatering component 5 and accelerating the drying speed of the raw materials. Based on this structure, since the feeder 2 is connected to the centrifugal dewatering component 5 through the power unit 6, when material is injected into the centrifugal dewatering component 5, the centrifugal dewatering component 5 generates centrifugal force, which not only separates the water in the material, but also uses the spiral blades 52 to carry the spun-dry material out through the base 1.
[0043] In a specific embodiment of this utility model, the centrifugal dehydration component 5 includes a centrifugal cylinder 51 and a magnetic coupling 54. The surface of the centrifugal cylinder 51 has several through holes to allow water to be spun out. A filter screen 53 is also fitted around the outside of the centrifugal cylinder 5 to prevent material leakage from the through holes. Furthermore, a magnetic coupling 54 is provided at the end of the centrifugal cylinder 51, coaxially connected to the centrifugal cylinder 51. Several permanent magnets 55 are circumferentially arranged at the end of the magnetic coupling 54, and a shaft tube 56 is located at the center of the magnetic coupling 54. This utility model, by providing helical blades 52 on the inner wall of the centrifugal cylinder 51, allows the helical blades 52 to rotate synchronously with the centrifugal cylinder 51. Compared to the prior art, the helical blades 52 and the centrifugal cylinder 51 are powered, and the material is spun out by the slip ratio between them. This not only simplifies the structure but also reduces component wear. Additionally, since there is no friction between the helical blades 52 and the centrifugal cylinder 51, noise generation is effectively reduced.
[0044] In this embodiment, the permanent magnet 55 is magnetically connected to the paired magnet 62, and several paired magnets 62 are arranged on the magnetic turntable 61. The magnetic turntable 61 is coaxially connected to the transmission wheel 63, and a central hole 66 is provided at the center of the magnetic turntable 61, penetrating the transmission wheel 63. The central hole 66 is fitted onto the shaft tube 56, thereby achieving the effect of magnetic coupling transmission. Furthermore, in this embodiment, the motor 65 serves as the power unit to drive the device, and the output shaft of the motor 65 is connected to the transmission wheel 63 via a transmission belt 64, thereby driving the centrifuge drum 51 to rotate. Compared with the prior art, this utility model adopts a flexible coupling transmission connection method, which can effectively reduce the instantaneous starting load of the motor and improve the service life of the motor.
[0045] In one specific embodiment of this utility model, the coaxial fan 4 includes a fan 41, a connecting shaft 42, and a cover 43. The cover 43 mainly serves as a coaxial connection, allowing the fan 41 to rotate synchronously with the centrifuge drum 51. Since the end of the centrifuge drum 51 is coaxially and fixedly connected to the cover 43, and one end of the cover 43 is connected to the connecting shaft 42, while the other end of the connecting shaft 42 is connected to the fan 41, when the fan 41 rotates, it can introduce airflow inward and use the airflow to blow off the material adhering to the inner wall of the centrifuge drum 51, preventing the dry material from caking under the action of centrifugal force.
[0046] In some embodiments, the base 1 includes a base body 11, a water collection tank 12, a drain outlet 13, a discharge outlet 14, and a fan slot 15. The fan slot 15 is located at the end of the base body 11. The water collection tank 12 is provided inside the base body 11. The drain outlet 13 is provided at the bottom of the water collection tank 12. The discharge outlet 14 is provided between the water collection tank 12 and the fan slot 15. The cover plate 3 is provided with an electric heating wire for heating the water collection tank 12. The water collection tank 12 is provided with a centrifugal dehydration component 5. The material dehydrated by the centrifugal dehydration component 5 is discharged from the discharge outlet 14. Thus, while completing the spin drying, the material can also be dried by heating with a coaxial fan 4, thereby further improving the drying effect of the material.
[0047] In some embodiments, the feeder 2 includes a feed trough 21, a conical funnel 22, and a feed pipe 23. The feed trough 21 is a cubic sheet metal part. The top of the feed trough 21 is provided with a conical funnel 22, which has a hollow structure inside. The bottom of the conical funnel 22 is connected to the feed pipe 23. Since the feed pipe 23 is connected to the shaft tube 56, raw materials are injected into the centrifuge cylinder 51.
[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
