Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screening machines, and specifically, to a rolling screening machine. Background Art
[0002] As an efficient and stable screening device, the rolling screening machine has been widely used in many industries such as mining, metallurgy, chemical industry, and building materials. With its unique rolling screening method, it realizes the efficient screening and fine classification of materials, providing a strong guarantee for the continuity and efficiency of the production process.
[0003] There are some drawbacks in the existing devices during use. For example, the existing rolling screening machine will experience blockage during actual use. The blockage of the screen not only causes a sharp decline in screening efficiency, affecting the overall operation efficiency of the production line, but also damages the screen due to excessive material accumulation, increasing the maintenance cost and downtime. The blocked screen will also cause unqualified materials to mix into the qualified products, seriously affecting the product quality. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a rolling screening machine to solve the problem that the existing rolling screening machine will experience blockage during actual use.
[0005] The utility model provides the following technical solution: a rolling screening machine, including a base, four support columns are fixedly connected to the upper end surface of the base, the tops of the four support columns are fixedly connected with an outer barrel, both ends of the outer barrel are rotatably connected with a rotating frame, a screen barrel is fixedly sleeved inside the two rotating frames, a driving component is arranged on the base, four fixing columns are arranged on the upper end surface of the base, a discharging component is arranged on the four fixing columns, and an anti-blocking component is arranged on the outer barrel.
[0006] In the above solution, the base serves as the foundation of the entire screening machine, and firmly supports components such as the outer barrel and the screen barrel through four support columns, ensuring the stability and safety of the equipment during operation. The rotational connection design between the rotating frame and the outer barrel enables the screen barrel to rotate smoothly under the drive of the driving component, reducing vibration and noise and improving the screening effect. The continuous rotation of the screen barrel allows the materials to continuously tumble, disperse, and fully contact the screen barrel, thereby achieving efficient screening. The addition of the anti-blocking component effectively prevents the blockage of the screen holes, ensuring the continuity and efficiency of the screening process, and further improving the screening efficiency and production capacity.
[0007] As a preference of the above technical solution, the screen barrel is inclined, and the two ends of the screen barrel are respectively set as an inlet end and an outlet end.
[0008] In the above solution, after the material enters the screen barrel from the inlet end, with the rotation of the screen barrel and the guidance of the inclination angle, it can continuously move towards the outlet end and complete screening during the movement. This continuous screening method reduces the residence time of the material on the screen barrel, improves the screening efficiency. The inclination angle helps the material form a continuous flow layer on the screen barrel, reducing the accumulation and retention of the material on the screen barrel, thereby reducing the risk of screen barrel blockage.
[0009] As an optimization of the above technical solution, the driving assembly includes mounting plates fixedly connected to the four corners of the upper end face of the base. Installation grooves are formed in all four mounting plates. Rotating shafts are arranged in all four installation grooves. Both ends of the four rotating shafts penetrate through both sides of the corresponding mounting plates and are rotatably connected to both sides of the mounting plates. Driving motors are fixedly connected to the outer walls of one side of two of the mounting plates. One ends of two of the rotating shafts close to the driving motors are fixedly connected to the output ends of the corresponding driving motors respectively. Rotating wheels are fixedly sleeved on the outer sides of all four rotating shafts.
[0010] In the above solution, the driving motor drives the rotating shaft to drive the rotating wheel to rotate synchronously, thereby driving the rotating frame to make the entire screen barrel rotate. This synchronous rotation method can ensure that the materials in the screen barrel are evenly screened and improve the screening efficiency.
[0011] As an optimization of the above technical solution, the driving assembly further includes rotating grooves annularly formed on the outer sides of the two rotating frames. The four rotating wheels are grouped in pairs. Two rotating wheels in the same group are respectively in contact with the corresponding rotating grooves.
[0012] In the above solution, through the direct contact between the rotating wheel and the rotating groove, direct transmission from the driving motor to the rotating frame is achieved. This method reduces the intermediate transmission links, improves the transmission efficiency, and reduces the energy loss. The two rotating wheels in the same group respectively act on the corresponding rotating grooves, ensuring that the two rotating frames can rotate synchronously, thereby maintaining the stability of the screen barrel and the uniformity of the screening effect.
[0013] As an optimization of the above technical solution, the discharging assembly includes a discharging baffle fixedly connected to the tops of the four fixed columns, and the upper end face of the discharging baffle is fixedly connected to the outer wall of one side of the outer barrel. A discharging groove is formed in the outer wall of the outer barrel close to the discharging baffle, and the discharging baffle communicates with the outer barrel through the discharging groove.
[0014] In the above solution, the materials completed screening by the screen barrel fall into the discharging baffle through the discharging groove. The design of the discharging baffle enables the materials to flow out smoothly along the predetermined path, reducing the residence time of the materials during discharging and improving the discharging efficiency.
[0015] As an optimization of the above technical solution, the anti-blocking component includes a mounting frame fixedly connected to the outer wall of one side of the outer barrel. A high-pressure blower is fixedly connected to the upper end face of the mounting frame. The output end of the high-pressure blower is fixedly connected to an air supply pipe, and the air supply pipe is communicated with the output end of the high-pressure blower. The end of the air supply pipe away from the high-pressure blower penetrates and is fixedly connected to the top end of the mounting frame. A connecting pipe is fixedly connected to the bottom end of the air supply pipe, and the connecting pipe is fixedly connected to the outer wall of one side of the outer barrel. A plurality of air outlet pipes are fixedly connected to the lower end face of the connecting pipe in an array. The plurality of air outlet pipes are communicated with the air supply pipe through the connecting pipe. The ends of the plurality of air outlet pipes away from the connecting pipe penetrate and are fixedly connected to the outer wall of one side of the outer barrel.
[0016] In the above solution, the high-pressure gas generated by the high-pressure blower is evenly distributed to the outside of the screen barrel through the air supply pipe, the connecting pipe and the plurality of air outlet pipes. The high-pressure gas can directly impact the materials on the screen barrel, thereby effectively preventing the blockage of the screen holes. Through timely anti-blocking treatment, the shutdown cleaning time caused by screen hole blockage is reduced, and the overall operation efficiency of the screening equipment is improved.
[0017] Compared with the prior art, the beneficial effects of the present utility model are:
[0018] In the present utility model, the high-pressure gas generated by the high-pressure blower in the anti-blocking component directly impacts the materials on the screen barrel. The strong air flow impact force can quickly disperse the material agglomerates and blow out the fine particles from the screen holes, thereby effectively preventing the screen holes from being blocked by the materials. This physical scouring effect is more direct and efficient than traditional vibration screening, especially for materials with high viscosity and easy caking, and its anti-blocking effect is particularly significant.

[0026] Embodiment 1
[0027] As Figure 1 and Figure 2 shown, the present invention provides a technical solution: a rolling screening machine, including a base 10, four support columns 11 are fixedly connected to the upper end surface of the base 10, the tops of the four support columns 11 are fixedly connected to an outer barrel 12, both ends of the outer barrel 12 are rotatably connected to a rotating frame 13, a screen barrel 14 is fixedly sleeved inside the two rotating frames 13, a driving assembly is arranged on the base 10, four fixed columns 15 are arranged on the upper end surface of the base 10, a discharge assembly is arranged on the four fixed columns 15, and an anti-blocking assembly is arranged on the outer barrel 12. In the specific use process, the base 10 serves as the foundation of the entire screening machine, and through the four support columns 11, it firmly supports components such as the outer barrel 12 and the screen barrel 14, ensuring the stability and safety of the equipment during operation. The rotational connection design between the rotating frame 13 and the outer barrel 12 enables the screen barrel 14 to rotate smoothly under the drive of the driving assembly, reducing vibration and noise and improving the screening effect. The continuous rotation of the screen barrel 14 enables the material to continuously tumble, disperse, and fully contact the screen barrel 14, thereby achieving efficient screening. The addition of the anti-blocking assembly effectively prevents the blockage of the screen holes, ensures the continuity and high efficiency of the screening process, and further improves the screening efficiency and production capacity.
[0028] As an implementation manner in this embodiment, as Figure 2 shown, the screen barrel 14 is inclined, and the two ends of the screen barrel 14 are respectively set as an inlet end 20 and an outlet end 21. In the specific use process, after the material enters the screen barrel 14 from the inlet end 20, with the rotation of the screen barrel 14 and the guidance of the inclination angle, it can continuously move towards the outlet end 21 and complete the screening during the movement. This continuous screening method reduces the residence time of the material on the screen barrel 14 and improves the screening efficiency. The inclination angle helps the material to form a continuous flow layer on the screen barrel 14, reducing the accumulation and retention of the material on the screen barrel 14, thereby reducing the risk of blockage of the screen barrel 14.
[0029] As an implementation method in this embodiment, as Figure 1 , Figure 2 and Figure 5 shown, the driving component includes mounting plates 30 fixedly connected to the four corners of the upper end face of the base 10. Mounting grooves 31 are formed in all four mounting plates 30. Rotating shafts 32 are arranged in all four mounting grooves 31. Both ends of the four rotating shafts 32 penetrate through both sides of the corresponding mounting plates 30 and are rotatably connected to both sides of the mounting plates 30. Driving motors 33 are fixedly connected to the outer walls of one side of two of the mounting plates 30. One ends of two of the rotating shafts 32 close to the driving motors 33 are fixedly connected to the output ends of the corresponding driving motors 33. Rotating wheels 34 are fixedly sleeved on the outer sides of the four rotating shafts 32. In the specific use process, the driving motors 33 drive the rotating shafts 32 to drive the rotating wheels 34 to rotate synchronously, thereby driving the rotating frame 13 to make the whole screen barrel 14 rotate. This synchronous rotation method can ensure that the materials in the screen barrel 14 are evenly screened, improving the screening efficiency.
[0030] As an implementation method in this embodiment, as Figure 1 and Figure 2 shown, the driving component further includes rotating grooves 40 annularly formed on the outer sides of the two rotating frames 13. The four rotating wheels 34 are grouped in pairs. The two rotating wheels 34 in the same group are respectively in contact with the corresponding rotating grooves 40. In the specific use process, through the direct contact between the rotating wheels 34 and the rotating grooves 40, the direct transmission from the driving motors 33 to the rotating frames 13 is realized. This method reduces the intermediate transmission links, improves the transmission efficiency, and reduces the energy loss. The two rotating wheels 34 in the same group respectively act on the corresponding rotating grooves 40, ensuring that the two rotating frames 13 can rotate synchronously, thereby maintaining the stability of the screen barrel 14 and the uniformity of the screening effect.
[0031] As an implementation method in this embodiment, as Figure 3 shown, the discharging component includes a discharging baffle 50 fixedly connected to the tops of the four fixed columns 15, and the upper end face of the discharging baffle 50 is fixedly connected to the outer wall of one side of the outer barrel 12. A discharging groove 51 is formed in the outer wall of the outer barrel 12 close to the discharging baffle 50, and the discharging baffle 50 is communicated with the outer barrel 12 through the discharging groove 51. In the specific use process, the materials screened by the screen barrel 14 fall into the discharging baffle 50 through the discharging groove 51. The design of the discharging baffle 50 enables the materials to flow out smoothly along a predetermined path, reducing the residence time of the materials during the discharging process and improving the discharging efficiency.
[0032] As an implementation method in this embodiment, as Figure 1 , Figure 2 and Figure 4As shown in the figure, the anti-blocking component includes a mounting frame 60 fixedly connected to the outer wall of one side of the outer barrel 12. The upper end surface of the mounting frame 60 is fixedly connected with a high-pressure blower 61. The output end of the high-pressure blower 61 is fixedly connected with an air supply pipe 62, and the air supply pipe 62 is communicated with the output end of the high-pressure blower 61. One end of the air supply pipe 62 away from the high-pressure blower 61 penetrates through the top end of the mounting frame 60 and is fixedly connected with the top end of the mounting frame 60. The bottom end of the air supply pipe 62 is fixedly connected with a connecting pipe 63, and the connecting pipe 63 is fixedly connected to the outer wall of one side of the outer barrel 12. The lower end surface of the connecting pipe 63 is fixedly connected with a plurality of air outlet pipes 64 in an array. The plurality of air outlet pipes 64 are communicated with the air supply pipe 62 through the connecting pipe 63. One end of the plurality of air outlet pipes 64 away from the connecting pipe 63 penetrates through the outer wall of one side of the outer barrel 12 and is fixedly connected with the outer wall of one side of the outer barrel 12. In the specific use process, the high-pressure gas generated by the high-pressure blower 61 is evenly distributed to the outside of the screen barrel 14 through the air supply pipe 62, the connecting pipe 63 and the plurality of air outlet pipes 64. The high-pressure gas can directly impact the materials on the screen barrel 14, thereby effectively preventing the blockage of the screen holes. Through timely anti-blocking treatment, the shutdown cleaning time caused by the blockage of the screen holes is reduced, and the overall operation efficiency of the screening equipment is improved.
[0033] Working principle: The driving motor 33 drives the rotating shaft 32 to drive the rotating wheel 34 to rotate synchronously, thereby driving the rotating frame 13 to make the whole screen barrel 14 rotate. After the materials enter the screen barrel 14 from the inlet end 20, under the guidance of the rotation and inclination angle of the screen barrel 14, the materials continuously tumble, disperse and contact the screen barrel 14. The materials that meet the screen aperture pass through the screen barrel 14 and fall to complete the screening. The materials that do not meet the aperture requirements continue to move forward and finally are discharged from the outlet end 21. The screened materials fall into the discharge baffle 50 through the discharge chute 51. The design of the discharge baffle 50 enables the materials to flow out smoothly along the predetermined path, reduces the residence time of the materials during the discharging process, and improves the discharging efficiency. In order to prevent the screen holes from being blocked, the high-pressure gas generated by the high-pressure blower 61 is evenly distributed to the outside of the screen barrel 14 through the air supply pipe 62, the connecting pipe 63 and the plurality of air outlet pipes 64, directly impacting the materials on the screen barrel 14, effectively preventing the blockage of the screen holes, and ensuring the continuity and high efficiency of the screening process.
