Description

Technical Field

[0001] This utility model belongs to the technical field of screening devices, specifically relating to a screening device for recycling renewable resources. Background Technology

[0002] Renewable resources refer to material resources that can be repeatedly recycled and processed after being developed and utilized once in human production and daily life activities and then scrapped. They cover multiple categories such as metals, non-metals, and electronic waste. They have significant advantages such as saving resources, reducing costs, and reducing pollution, and are an important support for the circular economy and sustainable development. After some renewable resources are recycled and processed, they need to be screened, so screening devices are required. However, some existing screening devices often have certain shortcomings in use and need to be improved.

[0003] Chinese patent CN220716572U discloses a multi-stage screening recycling device, including a housing with a screening chamber and a sieving chamber. A screening plate with different sized sieve holes is located between the screening chamber and the sieving chamber. A hydraulic cylinder is fixed to the lower end of the screening chamber, and a movable disc is fixedly connected to the upper end of the hydraulic cylinder through the screening chamber. The movable disc can move up and down within the screening chamber. A motor is installed inside the movable disc, and multiple rotating plates are fixed to the output shaft of the motor. The rotating plates are used to centrifuge the recycled resources to the sieve holes of the screening plate for screening. This invention uses a hydraulic cylinder to push the movable disc, which drives the rotating plates driven by the motor to rotate. Under centrifugal force, the recycled resources pass through the screening plates with different sized sieve holes, achieving sequential screening from small to large, resulting in good screening effect.

[0004] However, when using the above-mentioned technical solution, after the workers pour the particles from the feed hopper into the screening chamber, the motor drives the rotating plate to rotate, causing the particles to be screened layer by layer through the first layer of apertures inside the screening plate. However, if the particles at the bottom of the screening chamber have difficulty passing through the screening plate, the workers need to constantly adjust the height of the rotating plate to ensure that it can pass through the apertures inside the screening plate. Moreover, only the particles at the bottom of the screening chamber can be pushed by the rotating plate. The particles inside the screening chamber are affected by gravity, making them more compact. If they have difficulty passing through the first layer of apertures, and there are enough particles inside the screening chamber, the rotating plate will have difficulty rising when it moves upward, making it difficult for the particles to move upward and pass through the second layer of apertures on the screening plate for screening. This requires constant adjustments by the workers, which wastes time and has certain limitations in use. Utility Model Content

[0005] The purpose of this invention is to provide a screening device for recycling renewable resources, so as to solve the problems mentioned in the background art.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) This device uses the horizontal stirring of the spiral blades and the longitudinal shaking of the vibrating motor to fully disperse the particles, so that they fall into the corresponding material discharge chamber after passing through the screens of different diameters, thereby improving the screening pass rate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please see Figures 1 to 5As shown, a screening device for recycling renewable resources includes a support base 1, three material discharge chambers 2 inside the support base 1, a screening chamber 3 fixedly connected inside the support base 1, a drive motor 4 fixedly connected to the top of the surface of the support base 1, a spiral blade 5 fixedly connected to the output end of the drive motor 4, three screening screens 6 inside the screening chamber 3, two partitions 7 fixedly connected to the surface of the screening chamber 3, two vibration motors 8 fixedly connected to the top of the screening chamber 3, a material inlet inside the screening chamber 3, a slot inside the inner wall of the material inlet, a sealing plate 9 slidably connected to the inner wall of the slot, an inclined plate 10 fixedly connected to the inner wall of the material discharge chambers 2, a material outlet 11 fixedly connected to the bottom of one side of the support base 1, a blocking strip sliding through the inside of the material outlet 11, and a guide plate 12 fixedly connected through the inside of the material outlet 11.

[0018] The support base 1 provides support for the entire device. The feeding chamber 2 allows particles screened by the three screens 6 to be stored separately. The drive motor 4 rotates the spiral blades 5, thus agitating the particles inside the screening chamber 3. The vibration motor 8 vibrates the particles inside the screening chamber 3, improving the agitation effect when stirred by the spiral blades 5. The apertures of the three screens 6 increase sequentially from left to right; the aperture of the middle screen 6 is larger than that of the left screen 6 and smaller than that of the right screen 6, allowing for the screening of particles of different diameters, which are then stored separately. The partition 7... The screen 6 with different aperture sizes blocks the falling particles from the screen, preventing them from falling into the material discharge chamber 2. The inlet allows workers to add particles for subsequent screening. The sealing plate 9 closes the screening chamber 3, preventing particles from falling out. The inclined plate 10 guides the screened particles in the material discharge chamber 2 to the outlet 11. Then, the guide plate 12 guides them to the corresponding position. Workers can collect them at the bottom of the guide plate 12 using the appropriate collection device. The blocking strip seals the outlet 11, which acts as both a closing and opening mechanism. The outlet 11 is interconnected with the inside of the material discharge chamber 2, ensuring that the particles fall smoothly.

[0019] A support plate 13 is fixedly connected to the top of the back of the support base 1, a fixing block is fixedly connected to the middle of the back of the support plate 13, and a servo motor 14 is fixedly connected to the back of the fixing block.

[0020] The mounting plate 13 allows the fixing block to be fixed, and the fixing block facilitates the fixing of the servo motor 14.

[0021] The output end of the servo motor 14 is fixedly connected to a threaded rod 15, and a threaded sleeve is threaded through the surface of the threaded rod 15. A movable plate 17 is fixedly connected to the surface of the threaded sleeve.

[0022] The servo motor 14 provides a certain driving force for the rotation of the threaded rod 15. When the threaded rod 15 rotates, it will drive the threaded sleeve to move forward. When the servo motor 14 drives the threaded rod 15 to rotate in the opposite direction, the threaded sleeve will move backward.

[0023] Guide grooves 16 are provided on both sides of the top of the support plate 13. A sliding block is slidably connected inside the guide groove 16, and the bottom of the moving plate 17 is fixedly connected to the top of the sliding block. The opening of the guide groove 16 allows the sliding block to slide inside it, thereby making the moving plate 17 move more smoothly. A connecting short rod is fixedly connected to the middle of the bottom of the moving plate 17, and the connecting short rod is fixedly connected to the surface of the threaded sleeve to ensure its linkage.

[0024] A strip-shaped groove is formed in the middle of the top of the bearing plate 13, and one end of the threaded rod 15 is rotatably disposed inside the strip-shaped groove. Two limiting rods are fixedly connected to the surface of the threaded sleeve, and the bottom ends of the limiting rods are slidably connected to the inner sidewall of the strip-shaped groove. The strip-shaped groove allows the threaded rod 15 to rotate inside it, and the limiting rods provide guidance and limitation for the threaded sleeve during movement, making its movement smoother.

[0025] A sealing ring 18 is fixedly connected to the surface of the movable plate 17, and the surface of the sealing ring 18 extends through the interior of the screening chamber 3. After the movable plate 17 moves to a certain extent, it will cause the sealing ring 18 to block one end of the screening chamber 3. After the screening work is completed, it can be opened to facilitate the cleaning of its interior by the staff.

[0026] A control panel is fixedly connected to the top of one side of the support base 1, and the control panel is electrically connected to the drive motor 4, the vibration motor 8 and the servo motor 14 respectively.

[0027] The working principle of this invention is as follows: The operator first pours an appropriate amount of unevenly sized particles into the screening chamber 3 through the feed inlet, then closes the sealing plate 9. At this time, the operator controls the drive motor 4 to operate, and the output end of the drive motor 4 drives the spiral blades 5 to rotate, thus stirring the particles inside. Simultaneously, the vibration motor 8 operates, causing the particles inside the screening chamber 3 to shake, thus achieving better sieving while stirring. During shaking and stirring, the particles fall downwards due to gravity, passing through the screening mesh 6 with different aperture sizes, and finally falling downwards into the discharge chamber 2. The number of particles in the discharge chamber 2 continuously increases. When all the particles in the screening chamber 3 have been screened, this... Workers pull the blocking strips to one side in sequence, and simultaneously place the collecting device under the corresponding guide plate 12. This allows the particles inside the discharge chamber 2 to slide down through the inclined plate 10 and finally enter the collecting device through the guide plate 12. Then, subsequent screening can be carried out. After the screening is completed, the workers control the servo motor 14 to work. The output end of the servo motor 14 drives the threaded rod 15 to rotate, which in turn causes the threaded sleeve to move backward, thereby causing the moving plate 17 to move backward. At this time, the sealing ring 18 moves with it, separating it from the screening chamber 3. Then, the workers can use the corresponding device to clean the inside, or they can clean the inside through the feed port for convenient subsequent use.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
