[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] In the existing technology, the discharge gate of the three-dimensional vibrating screen adopts single-axis control or a gateless design. The gate has poor stability and is prone to material leakage. Furthermore, when screening materials, the screened powder material tends to accumulate at the edge of the screen, and the particulate material tends to clog the screen, affecting the material discharge efficiency and screening quality.
[0018] In view of this, the present invention provides a dual-axis gate three-dimensional vibrating screen. Through the cooperation of the base, support frame, screen frame, screen, discharge port, horizontal guide pipe, inclined guide pipe, discharge pipe, gate baffle, dual-axis cylinder, ball support plate, material leakage hole, rubber ball, rubber ring, vertical pipe and ultrasonic transducer, the dual-axis cylinder drives and controls the gate baffle. In the high-speed vibrating working environment, it can provide more stable support and driving force for the gate baffle. Furthermore, the bouncing impact of the rubber ball on the screen and the ultrasonic transducer cause the screen to generate ultrasonic vibration. Under the multiple effects of three-dimensional vibrating motion, rubber ball bouncing impact and ultrasonic vibration, the material is quickly screened and discharged from the discharge port, avoiding the formation of blockage or accumulation of material at the top and edge of the screen, effectively improving screening efficiency and screening accuracy.
[0019] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0020] Depend on Figure 1-4 It is known that a dual-axis gate three-dimensional vibrating screen includes a base 1, a support frame 2 on the top of the base 1, a ball panel 26 fixedly connected to the top of the support frame 2, screen frames 3 equidistantly arranged on the top of the support frame 2, a screen mesh 4 arranged on the inner bottom side of the screen frame 3, a discharge port 7 opened on one side of the screen frame 3, a horizontal guide pipe 8 fixedly connected to the outer wall of the screen frame 3 outside the discharge port 7, an inclined guide pipe 9 connected to the bottom of the horizontal guide pipe 8, a discharge pipe 10 connected to the bottom of the inclined guide pipe 9 away from the screen frame 3, and a dual-axis cylinder 1 fixedly connected to the side of the horizontal guide pipe 8 away from the screen frame 3. 2. A gate baffle 11 is fixedly connected to the output end of the dual-shaft cylinder 12. The gate baffle 11 is correspondingly set to the discharge port 7. The gate baffle 11 is connected to the outer wall of the screen frame 3. A ball support plate 13 is set below the screen 4. The outer wall of the ball support plate 13 is provided with leakage holes 14 at equal intervals. Rubber rings 16 are provided at equal intervals on the top of the ball support plate 13. Rubber balls 15 are provided at equal intervals inside the rubber rings 16. A vertical pipe 17 is fixedly connected to the top of the support frame 2. The vertical pipe 17 is fixedly connected to the screen 4 and the ball support plate 13 respectively. Ultrasonic transducers 18 are installed at equal intervals inside the vertical pipe 17.
[0021] In the specific implementation process, it is worth noting that, through the cooperation between the base 1, support frame 2, screen frame 3, screen 4, and spherical panel 26, the three-dimensional vibrating screen adopts a multi-layer screening structure design. Adjacent screen frames 3 are connected and fixed at their closest ends. The aperture size of each screen 4 can be adjusted according to actual needs. After the material enters the top layer of the three-dimensional vibrating screen, the support frame 2 drives the screen frame 3 and screen 4 to perform three-dimensional vibrating motion. The material is screened on the screen 4; materials smaller than the aperture of the screen 4 enter the next screening layer, while materials larger than the aperture of the screen 4 move to the edge of the screen 4 under the action of the vibration force, achieving precise screening of materials of different particle sizes. The spherical panel 26 is used at the bottom layer of the three-dimensional vibrating screen. The screened material is guided by the cooperation of the screen frame 3, discharge port 7, horizontal guide pipe 8, inclined guide pipe 9, and discharge pipe 10. Under the action of the vibration force, the screened material enters the horizontal guide pipe 8 through the discharge port 7, then enters the inclined guide pipe 9 from the horizontal guide pipe 8, and finally is discharged through the discharge pipe 10, thus realizing the discharge of the screened material. Through the cooperation of the screen frame 3, discharge port 7, horizontal guide pipe 8, inclined guide pipe 9, discharge pipe 10, gate baffle 11, and double-shaft cylinder 12, a sealing gasket is provided on the side of the gate baffle 11 near the screen frame 3. When no discharge is being performed, the sealing gasket of the gate baffle 11 is pressed against the screen frame 3 to close the discharge port 7, thereby improving the sealing between the gate baffle 11 and the discharge port 7. To prevent material leakage from the gap between the gate baffle 11 and the screen frame 3, when discharge is required, the dual-shaft cylinder 12 is controlled to drive the gate baffle 11 to move away from the screen frame 3, releasing the gate baffle 11 from the discharge port 7. This allows the material inside the screen frame 3 to enter the horizontal guide pipe 8 and the inclined guide pipe 9 under the action of the gyratory force, achieving precise control of the material discharge. Through the cooperation between the screen 4, the ball support plate 13, the leakage hole 14, the rubber ball 15, and the rubber ring 16, during the material screening process, the rubber ball 15 bounces within the rubber ring 16 between the screen 4 and the ball support plate 13, impacting the screen 4 and preventing particle material from clogging the screen 4, thus improving the material's screening rate. Furthermore, this design ensures that the material is more evenly distributed on the screen 4 during the screening process, preventing material accumulation and clogging, thereby improving the screening efficiency for granular materials. Through the cooperation between the support frame 2, screen 4, vertical pipe 17, and ultrasonic transducer 18, when screening fine powder materials, the ultrasonic generator is controlled to cause the ultrasonic transducer 18 to generate ultrasonic vibrations, which are then transmitted to the screen 4 through the vertical pipe 17. This further promotes the screening of the material, and the screened material is quickly discharged from the outlet 7 under the combined effects of three-dimensional rotary vibration, the bouncing impact of the rubber ball 15, and ultrasonic vibration. This prevents material from accumulating on the top and edges of the screen 4, effectively improving screening efficiency and accuracy.Through the cooperation of the base 1, support frame 2, screen frame 3, screen 4, discharge port 7, horizontal guide pipe 8, inclined guide pipe 9, discharge pipe 10, gate baffle 11, dual-axis cylinder 12, ball support plate 13, material leakage hole 14, rubber ball 15, rubber ring 16, vertical pipe 17, and ultrasonic transducer 18, the dual-axis cylinder 12 drives and controls the gate baffle 11. In a high-speed rotary vibration working environment, it can provide more stable support and driving force for the gate baffle 11. The bouncing impact of the rubber balls 15 on the screen 4 and the ultrasonic transducer 18 cause the screen 4 to vibrate ultrasonically. This allows the material to be rapidly screened under the combined effects of the three-dimensional rotary vibration, the bouncing impact of the rubber balls 15, and the ultrasonic vibration, and then discharged through the outlet 7. This prevents material from clogging or accumulating at the top and edges of the screen 4, effectively improving screening efficiency and accuracy. The specific models of the dual-shaft cylinder 12 and the ultrasonic transducer 18 are not limited; they only need to meet the usage requirements.
[0022] Furthermore, a mesh frame 5 is connected to the bottom inner side of the screen frame 3, the top of the mesh frame 5 is fixedly connected to the screen 4, the mesh frame 5 is connected to the ball support plate 13, a fixing ring 6 is provided on the outer side of the mesh frame 5, the mesh frame 5 and the fixing ring 6 are respectively connected to the outer wall of the two screen frames 3 that are close to each other, and a fixing clip 25 is provided on the outer side of the fixing ring 6.
[0023] In the specific implementation process, it is worth noting that the screen 4 and the ball support plate 13 are fixed to the screen frame 5 through the cooperation between the support frame 2, screen frame 3, screen 4, screen frame 5, fixing ring 6 and fixing clip 25. The screen frame 5 provides support on the inner side of the connection of the screen frame 3, and the fixing ring 6 is placed on the outer side of the connection of the screen frame 3. The fixing clip 25 is used to quickly lock the fixing ring 6, so as to realize the quick installation of each screen frame 3, enhance the stability of the connection of the screen frame 3. The screen frame 3 and screen 4 adopt a separable design, which can facilitate the disassembly, cleaning or replacement of the screen 4 and the ball support plate 13. The number of screen frames 3 and screen 4 can be adjusted according to the screening requirements, improving the maintenance convenience and usage flexibility of the equipment.
[0024] Furthermore, a conical plate 19 is provided at the bottom of the support frame 2, and a vibration motor 20 is fixedly connected to the bottom of the conical plate 19. Springs 21 are fixedly connected at equal intervals to the top of the machine base 1, and the end of the spring 21 away from the machine base 1 is fixedly connected to the support frame 2.
[0025] In the specific implementation process, it is worth noting that through the cooperation between the base 1, support frame 2, conical plate 19, vibrating motor 20 and spring 21, the support frame 2 is elastically supported on the top of the base 1 by the spring 21. Under the action of the vibrating motor 20, the support frame 2 generates high-frequency vibration, which is transmitted to the screen frame 3 and screen 4 through the spring 21, so that the material on the screen 4 is subjected to three-dimensional excitation force, thereby achieving efficient screening of the material. The specific model of the vibrating motor 20 is not limited, as long as it meets the usage requirements.
[0026] Furthermore, a dust cover 22 is provided on the top of the upper screen frame 3. The dust cover 22 is connected to the fixing ring 6. A feed inlet 23 is provided on the top of the dust cover 22.
[0027] In the specific implementation process, it is worth noting that through the cooperation between the dust cover 22 and the feed inlet 23, the dust cover 22 is sealed on the top of the three-dimensional vibrating screen, which effectively prevents the material from splashing out during the screening process. At the same time, it avoids dust from entering the screening device and affecting the screening quality. The setting of the feed inlet 23 makes it convenient to put the material into the three-dimensional vibrating screen for screening.
[0028] Furthermore, a dispersion cone 24 is provided at the top of the vertical tube 17;
[0029] In the specific implementation process, it is worth noting that through the cooperation between the vertical pipe 17 and the dispersing cone 24, the input material can be evenly dispersed on the screen 4, avoiding the accumulation of material in the center of the screen 4, and further improving the screening efficiency.
