Description

Technical Field

[0001] This utility model belongs to the field of drum screen technology, specifically relating to a novel energy-saving drum screen without a main shaft. Background Technology

[0002] Rotary drum screens are widely used in sorting technology, controlling waste sorting by particle size and offering high sorting accuracy. Currently, most rotary drum screens on the market are driven by a central rotating shaft, which has the following drawbacks: ① With increasing production efficiency, the diameter of the drive shaft is generally designed to be φ80-100cm, resulting in steel waste and increased manufacturing costs for the same production efficiency; ② Using a main shaft drive increases the driving torque, leading to increased power consumption; ③ The main shaft drive method is prone to bending and deformation, increasing maintenance costs. Therefore, improvements are necessary to address these issues. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a novel shaftless energy-saving rotary screen. By optimizing the rotary screen structure, the rotary screen, including the screen cylinder and filter frame, is rolled and supported on the support frame by a rolling support drive device. The rotary screen is driven to rotate shaftlessly by the rolling support drive device, which changes the transmission method of the traditional rotary screen, reduces the power of the drive motor by 30%, greatly reduces power consumption, and reduces the diameter of the rotating shaft to complete the normal operation of the rotary screen. This reduces the amount of steel used in the main shaft, thereby reducing the production and manufacturing costs under the same production efficiency. The rotary screen with screen cylinder and filter frame can separate and remove stones and impurities in one pass while screening the remaining materials again, achieving efficient separation and screening of materials. The structure is simple, the design is novel, stable and reliable, with good strength and low cost, and has high value for promotion and application.

[0004] The technical solution adopted by this utility model is as follows: a novel shaftless energy-saving rotary screen, including a support frame, a material trough and a rotary screen. The lower half of the rotary screen is located in the material trough, and the material trough is supported and fixed on the support frame. The support frame is provided with a rolling support drive device that is adapted to and connected to both ends of the rotary screen and is used for rolling support and driving the rotary screen to rotate. The rotary screen includes a screen cylinder and a filter frame fixed inside the screen cylinder for separating and removing stones and impurities in the material in one step.

[0005] The rolling support drive device includes a support wheel, a drive wheel, and a reducer. The reducer is located on one side of the material trough and fixed to the middle of the upper end face of the support frame on the same side. The two coaxial output shafts of the reducer are fixedly connected to one end of the transmission shaft on the same side, and the other end of the transmission shaft is fixedly connected to the drive wheel shaft, which is rotatably supported on the upper end of the support frame and adapted to the raceway groove at the corresponding end of the screen cylinder, through a universal joint. Support wheels adapted to the raceway groove at the corresponding end of the screen cylinder are rotatably installed at both ends of the upper end face of the other side of the support frame. The driven pulley fixed on the input shaft of the reducer is connected to the driving pulley on the output shaft of the motor through a V-belt, and the screen cylinder is driven without shafts under the drive of the motor.

[0006] Furthermore, two retaining rings provided on the outer wall of the steel rings at both ends of the screen cylinder form a raceway groove for adaptation to the support wheel and drive wheel.

[0007] Furthermore, the screen cylinder includes a steel ring frame and a screen mesh fixedly wound around the outer wall of the steel ring frame, and the filter frame is fixed on the inner frame wall of the steel ring frame.

[0008] Furthermore, the filter frame includes a hexagonal frame formed by six adjacent side plates fixedly connected together and a triangular support frame fixed to the edge of the hexagonal frame. The triangular support frame is fixed to the inner frame wall of the steel ring skeleton on the corresponding side.

[0019] New type of shaftless energy-saving rotary screen, such as Figure 1-3 As shown, the structure includes a support frame 1, a material trough 2, and a rotary screen 3. The lower half of the rotary screen 3 is located inside the material trough 2, and the material trough 2 is supported and fixed on the support frame 1. The support frame 1 is provided with a rolling support drive device that is adapted to and connected to both ends of the rotary screen 3 and is used for rolling support and driving the rotary screen 3 to rotate. The rotary screen 3 includes a screen cylinder 3-1 and a filter frame 3-2 fixed inside the screen cylinder 3-1 for separating and removing stones and impurities from the material in one pass. In the above structure, by optimizing the structure of the rotary screen 3, the rotary screen 3 is driven to rotate without a shaft by the rolling support drive device, which changes the traditional transmission method of the rotary screen 3, reduces the power of the drive motor by 30%, greatly reduces power consumption, and the rotary screen can be operated normally by reducing the diameter of the rotating shaft, which reduces the amount of steel used in the main shaft and reduces the production and manufacturing cost under the same production efficiency.

[0020] like Figure 1-2 As shown, the specific structure of the rolling support drive device is as follows: The rolling support drive device includes a support wheel 4, a drive wheel 5, and a reducer 6. The reducer 6 is located on one side of the material trough 2 and fixed to the middle of the upper end face of the support frame 1 on the same side. The two coaxially arranged output shafts of the reducer 6 are fixedly connected to one end of the transmission shaft 7 on the same side, and the other end of the transmission shaft 7 is fixedly connected to the shaft of the drive wheel 5, which is rotatably supported on the upper end of the support frame 1 and adapted to the raceway groove 8 at the corresponding end of the screen cylinder 3-1, through a universal joint. The two ends of the upper end face of the other side of the support frame 1 are rotatably mounted with the drive wheel 5, which is adapted to the raceway groove 8 at the corresponding end of the screen cylinder 3-1. The support wheel 4 is adapted to the end track groove 8. The driven pulley fixed on the input shaft of the reducer 6 is connected to the driving pulley on the output shaft of the motor 9 via a V-belt, and the screen cylinder 3-1 is driven by the motor 9 to achieve shaftless drive. Specifically, two retaining rings are set on the outer wall of the steel ring at both ends of the screen cylinder 3-1 to form the track groove 8 adapted to the support wheel 4 and the drive wheel 5. Specifically, the specific structure of the screen cylinder 3-1 is as follows: the screen cylinder 3-1 includes a steel ring skeleton and a screen mesh fixedly wound on the outer wall of the steel ring skeleton, and the filter frame 3-2 is fixed on the inner frame wall of the steel ring skeleton; wherein, as Figure 3 As shown, the specific structure of the filter frame 3-2 is as follows: The filter frame 3-2 includes a hexagonal frame 3-22 formed by six adjacent frame plates 3-21 fixedly connected to each other, and a triangular support frame 3-23 fixed to the edge of the hexagonal frame 3-22. The triangular support frame 3-23 is fixed to the inner frame wall of the steel ring skeleton on the corresponding side. The filter frame 3-2 with this structure has good structural strength and long service life. In the above structure, by optimizing the structure of the roller screen 3, the roller screen 3 formed by the screen cylinder 3-1 and the filter frame 3-2 with the hexagonal mesh structure can realize the separation and removal of stones and debris at one time, while the remaining materials are screened again, realizing the efficient separation and screening of materials.

[0021] In this scheme, after the motor 9 starts, it drives the reducer 6 to rotate via a V-belt. The two output shafts of the reducer 6 drive the transmission shaft 7 and the drive wheel 5 on the same side to rotate. Under the relative friction between the drive wheel 5 and the raceway trough 8, the roller screen 3 rotates. The material entering the roller screen 3 is located in the filter frame 3-2. The mesh filter frame 3-2 separates and removes stones and impurities from the material. The material entering the screen cylinder 3-1 is screened a second time by the screen on the upper part during the rotation process, thus achieving efficient separation and screening.

[0022] This technical solution has a simple structure, novel design, is stable and reliable, has good strength, and low cost, making it highly valuable for widespread application.
