DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 6 As shown, a chemical additive particle vibrating screening structure of the present invention comprises a material holding barrel 1 and a power unit 2, wherein the material holding barrel 1 is vertical, and the power unit 2 is used to drive the material holding barrel 1 to perform circular translation motion on a horizontal plane; The inner wall of the material barrel 1 is provided with a spiral plate 3, and a retaining edge 4 for blocking raw materials is provided on the edge of the spiral plate 3 away from the inner wall of the material barrel 1. A sealed spiral channel 5 is provided at the bottom of the spiral plate 3. A bottom plate 6 is provided at the bottom of the material barrel 1. The bottom plate 6 is used to carry the raw materials, and when the material barrel 1 moves, the raw materials on the bottom plate 6 climb onto the spiral plate 3 due to centrifugal action and inertia and are spirally transported upward along the spiral plate 3; The spiral plate 3 is densely covered with sieve holes for screening raw materials, a discharge channel 7 is arranged on the side wall of the material holding barrel 1, the discharge channel 7 is connected to the highest point of the spiral plate 3, and a discharge structure 8 for discharging materials is arranged at the bottom of the spiral channel 5.

[0020] In detail, the power unit 2 can provide power for the movement of the material barrel 1, so that the material barrel 1 can perform circular translational motion on the horizontal plane. At this time, the material barrel 1 does not rotate, and the material barrel 1 will drive the spiral plate 3, the rib 4, the spiral channel 5, the bottom plate 6, the discharge channel 7 and the discharge structure 8 thereon to move synchronously. The setting of the spiral plate 3 is mainly used to make use of the mass and inertia of the large-particle auxiliary raw material to enable it to move upward along the spiral plate 3, thereby automatically separating the large-particle raw material from the small-particle raw material, and the sieve holes on the spiral plate 3 can allow the small-particle raw material to fall into the spiral channel 5. Since the raw material rolls on the spiral plate 3, the small-particle raw material adsorbed on the surface of the large-particle raw material can be easily rolled off The raw materials on the spiral plate 3 fall and fall into the spiral channel 5. The retaining edge 4 is mainly used to prevent the raw materials on the spiral plate 3 from falling off the edge of the spiral plate 3. Since the spiral plate 3 and the spiral channel 5 are both spiral-shaped, the vacant area in the middle of the material barrel 1 can be used to continuously introduce the raw materials into the material barrel 1. Since the raw materials on the chassis 6 need to be moved to the spiral plate 3, the upper surface of the chassis 6 is coplanar with the lowest point of the spiral plate 3, and the discharge channel 7 is installed on the outer wall of the material barrel 1 to be connected to the highest point of the spiral plate 3. In this way, when the large-particle raw materials climb to the highest point of the spiral plate 3, due to the action of centrifugal force, the large-particle raw materials can automatically enter the discharge channel 7 and be discharged, and the small-particle raw materials collected in the spiral channel 5 can be discharged through the discharge structure 8.

[0021] When in use, the power unit 2 drives the material barrel 1 and the structure above it to perform circular translational motion, and the auxiliary agent granular raw material is continuously fed to the middle position of the material barrel 1 through the top opening of the material barrel 1, and the raw material falls onto the bottom plate 6. Since the bottom plate 6 performs circular translational motion, the raw material on the bottom plate 6 performs centrifugal motion and moves toward the inner wall of the material barrel 1. When the raw material moves to the end position on the lower side of the spiral plate 3, the raw material rolls onto the spiral plate 3 due to inertia. Since the spiral plate 3 moves with the material barrel 1, the spiral plate 3 can provide friction force for the raw material particles, so that the raw material The particles smoothly perform a spiral climbing motion on the spiral plate 3. Small particle raw materials can pass through the sieve holes on the spiral plate 3 and enter the spiral channel 5. However, large particle raw materials have large inertia and cannot pass through the sieve holes. Therefore, large particle raw materials can climb on the spiral plate 3 to the position of the discharge channel 7 and be discharged through the discharge channel 7. The small particle raw materials screened in the spiral channel 5 can be discharged through the discharge structure 8, thereby realizing the automatic vibration screening of the raw materials. Since the auxiliary agent particles can be continuously introduced into the material holding barrel 1, the continuous screening working mode of the auxiliary agent particles can be realized.

[0022] It should be pointed out that, since the material barrel 1 performs circular translational motion, it can ensure that the raw materials on the chassis 6 can achieve centrifugal motion. Compared with the traditional static rotation method, it can avoid the raw materials from gathering in the middle position of the chassis 6. Since the material barrel 1 is in motion, in order to connect the discharge channel 7 with the collecting device, the discharge channel 7 can be made of soft rubber material to achieve a soft connection effect.

[0023] By continuously feeding materials into the material holding barrel 1, the auxiliary agent particles can continuously enter the system, and at the same time, the large-particle raw materials and the small-particle raw materials can be discharged through the discharge channel 7 and the discharge structure 8 respectively, thereby achieving a continuous screening effect, without repeatedly turning the machine on and off, and improving work efficiency; by utilizing the annular translation movement of the material holding barrel 1, the raw materials on the chassis 6 can be quickly moved toward the inner wall of the material holding barrel 1, and the inertia and centrifugal force of the raw materials can be used to move them upward along a spiral path. Due to the different mass and inertia of the raw materials, the automatic separation of large-particle raw materials and small-particle raw materials can be achieved, and the rolling of the large-particle raw materials can be conveniently sucked upward. The attached small particles of raw materials roll off, and the screening work of the sieve holes on the spiral plate 3 is used to realize multiple screening methods for raw materials, improve the screening effect, and the setting of the spiral plate 3 can increase the screening path length, improve the screening efficiency and accuracy; the entire screening process is completed automatically, reducing the labor intensity of workers and reducing the error of manual operation; in summary, a chemical additive particle vibration screening structure not only solves the problems of low efficiency, poor accuracy, and high labor intensity in traditional screening methods, but also provides a new solution for efficient production and quality control in the chemical industry through high automation and flexibility. The application of this technology will significantly improve product quality and production efficiency, and bring significant economic and social benefits to related enterprises.

[0024] Furthermore, the power unit 2 includes two power wheels 9 located on the left and right sides of the material barrel 1 and a first connecting ring 10 fixedly mounted on the outer wall of the material barrel 1, the axis of the power wheel 9 is vertical, and the plane where the axes of the two power wheels 9 are located deviates from the vertical axis of the material barrel 1, and an eccentric column 11 is eccentrically arranged on the power wheel 9, and the eccentric column 11 is connected to the first connecting ring 10 through a connecting rod 12, and the eccentric column 11 is rotatably connected to the connecting rod 12; The axes of the two eccentric columns 11 and the axis of the material holding barrel 1 are coplanar.

[0025] In detail, when the two power wheels 9 rotate synchronously in the same direction, they will drive the two eccentric columns 11 to perform synchronous eccentric circular motion. At this time, the eccentric column 11 drives the first connecting ring 10 and the material bucket 1 to perform synchronous eccentric motion through the connecting rod 12, thereby enabling the material bucket 1 to achieve a circular translational motion. The arrangement of the two power wheels 9 and the structures thereon can ensure that the material bucket 1 and the first connecting ring 10 will not rotate on their own.

[0026] Furthermore, a plurality of auxiliary rollers 13 are rotatably provided on the outer wall of the first connecting ring 10 , and the two power wheels 9 are connected by a transmission belt 14 , and the transmission belt 14 is sleeved on the plurality of auxiliary rollers 13 on the outer wall of the first connecting ring 10 .

[0027] In detail, when one power wheel 9 rotates, it can drive the other power wheel 9 to rotate synchronously and in the same direction through the transmission belt 14. The setting of the auxiliary roller 13 can help the transmission belt 14 to be smoothly transported on the first connecting ring 10 to avoid mutual friction between the transmission belt 14 and the first connecting ring 10. It should be pointed out that since the first connecting ring 10 and the material holding bucket 1 perform circular translational motion, the distance between the first connecting ring 10 and each power wheel 9 will always change. At this time, the small elastic deformation effect of the transmission belt 14 itself can be used to enable the two power wheels 9 to always transmit power through the transmission belt 14.

[0028] Furthermore, a slide groove is provided on the power wheel 9 , and the slide groove passes through the axis of the power wheel 9 . A first slider 15 is slidably arranged in the slide groove, and the first slider 15 is fastened to the power wheel 9 by bolts, and the eccentric column 11 is fixed on the first slider 15 .

[0029] In detail, the power wheel 9 can drive the eccentric column 11 to perform eccentric circular motion through the first slider 15. When it is necessary to adjust the movement radius of the bucket 1, that is, to adjust the vibration amplitude of the bucket 1, the bolts on the first slider 15 can be loosened and the position of the first slider 15 in the slide groove can be moved. When the adjustment of the first slider 15 is completed, the bolts can be tightened. It should be pointed out here that since the overall length of the transmission belt 14 changes little when the first connecting ring 10 adjusts its position, it does not affect the transmission work of the two power wheels 9.

[0030] Further, the discharge structure 8 includes a first material guide pipe 16, a second material guide pipe 17 and a collection box 18. The first material guide pipe 16 and the second material guide pipe 17 are both inclined. The top of the first material guide pipe 16 is connected to the bottom of the spiral channel 5. Both ends of the second material guide pipe 17 are provided with a column 19. Each column 19 is rotatably buckled with a buckle slot plate 20. One buckle slot plate 20 is connected to the bottom of the first material guide pipe 16, and the bottom of the other buckle slot plate 20 is connected to a vertical pipe 21. The vertical pipe 21 is vertically inserted into the collection box 18, and the vertical pipe 21 rotates on the collection box 18. The axis of the vertical pipe 21 coincides with the circular motion axis of the material holding barrel 1 , and openings are provided on both columns 19 , through which the second material guiding pipe 17 is connected to the buckle groove plate 20 .

[0031] In detail, the small particle raw materials collected by the spiral channel 5 can be introduced into the collection box 18 through the first guide pipe 16, two buckle groove plates 20, two cylinders 19, the second guide pipe 17 and the vertical pipe 21. Since the material barrel 1 performs a circular translational motion, the material barrel 1 will drive the second guide pipe 17, the cylinder 19, the buckle groove plate 20 and the vertical pipe 21 to rotate on the collection box 18 through the first guide pipe 16. At this time, the vertical pipe 21 performs a self-rotation motion, and the various structures on the discharge structure 8 remain connected. When the first slider 15 moves on the power wheel 9 and adjusts the movement radius of the material barrel 1, since the position of the collection box 18 is fixed, the material barrel 1 will push the vertical pipe 21 to slide vertically on the collection box 18 through the first guide pipe 16, the second guide pipe 17, the cylinder 19 and the buckle groove plate 20, and the first guide pipe 16 will push the inclination angle of the second guide pipe 17 to change, the cylinder 19 rotates in the buckle groove plate 20 thereon, and the various structures on the discharge structure 8 remain connected.

[0032] Furthermore, an auxiliary slot plate 27 is provided on the side wall of the collection box 18, and the auxiliary slot plate 27 is connected to the collection box 18 through a plurality of air holes 28, and an air pipe 29 is provided on the side wall of the auxiliary slot plate 27; When the air pipe 29 supplies air to the collecting box 18, the air in the spiral channel 5 passes through the sieve holes on the spiral plate 3 and enters the material holding barrel 1 in the reverse direction. When the air pipe 29 draws air out of the collecting box 18, the air in the material holding barrel 1 passes through the sieve holes on the spiral plate 3 and enters the spiral channel 5 in the forward direction.

[0033] In detail, by setting up the air pipe 29, the air flow can be involved in the screening of raw materials. When the air pipe 29 is evacuated, the air in the material barrel 1 will enter the spiral channel 5 through the sieve holes. At this time, the air flow can help small-particle raw materials to quickly pass through the sieve holes, thereby accelerating the screening work, and can simultaneously clean the dust in the material barrel 1. When the air pipe 29 supplies air, the air in the spiral channel 5 enters the material barrel 1 through the sieve holes in the opposite direction. At this time, the air flow can clean the granular raw materials that block the sieve holes, thereby improving the fluidity of the sieve holes. In actual use, the air pipe 29 only needs to be opened periodically for air supply. The setting of the air holes 28 can help intercept the particles in the collection box 18 from entering the auxiliary slot plate 27.

[0034] Further, a vertical channel 22 is provided on the side wall of the collecting box 18, a slide plate 23 is vertically slidably provided in the vertical channel 22, a storage groove 24 is provided on the side wall of the slide plate 23 facing the collecting box 18, the bottom surface of the storage groove 24 is inclined, and its inclination direction gradually decreases from the side away from the collecting box 18 to the side close to the collecting box 18, a discharge port 25 is provided on the side wall of the collecting box 18 facing the slide plate 23, the discharge port 25 is communicated with the storage groove 24, a cylinder 26 is fixed on the collecting box 18, the movable end of the cylinder 26 is fixedly connected to the slide plate 23, and the cylinder 26 provides power for the up and down movement of the slide plate 23; The bottom surface of the collecting box 18 is inclined, and when the slide plate 23 moves downward and causes the receiving groove 24 to deviate from the discharge opening 25 , the side wall of the slide plate 23 blocks the discharge opening 25 .

[0035] In detail, since there is gas flow in the collecting box 18, in order to prevent outside air from entering the collecting box 18 through the discharge port 25, it is necessary to utilize the structural mode of the vertical channel 22 and the slide plate 23. In the natural state, the receiving groove 24 moves to the height position of the discharge port 25. At this time, the raw materials collected in the collecting box 18 can enter the receiving groove 24 through the discharge port 25. When the cylinder 26 extends and pushes the slide plate 23 to move downward, the slide plate 23 will carry the raw materials in the receiving groove 24 and move downward synchronously. The vertical channel 22 guides the slide plate 23. When the receiving groove 24 deviates from the discharge port 25, the side wall of the slide plate 23 will block the discharge port 25. When the receiving groove 24 moves to the outside of the vertical channel 22, the raw materials in the receiving groove 24 naturally slide down and are discharged, thereby realizing the discharge work. When the cylinder 26 contracts and resets the slide plate 23, the receiving groove 24 is connected with the discharge port 25 again, so that it can be ensured that when the raw materials are discharged, the outside air cannot enter the collecting box 18 through the discharge port 25.

[0036] Furthermore, a frame 30 and a supporting structure for supporting the material barrel 1 are provided on the outside of the material barrel 1, and the collection box 18 is installed on the frame 30. Two support shafts 31, a motor 32 and a transmission wheel 33 are provided on the frame 30. The two support shafts 31 are respectively connected to the two power wheels 9, and the support shafts 31 rotate on the frame 30. The motor 32 provides power for the transmission wheel 33, and the transmission wheel 33 is connected to a support shaft 31 in a transmission manner. The supporting structure includes a second connecting ring 34 and two guide rails 35. The second connecting ring 34 is set and fixed on the outer wall of the material bucket 1. The two guide rails 35 are respectively located on the left and right sides of the material bucket 1 and are fixed on the side walls of the frame 30. The guide rails 35 are horizontal. A slide seat 36 is slidably provided on the guide rail 35. A second slider 37 is slidably provided on the slider 36. Two support rods 38 in a crossed state are provided between the guide rail 35 and the second connecting ring 34. One ends of the two support rods 38 are rotatably mounted on the second connecting ring 34, the other end of one support rod 38 is rotatably mounted on the slider 36, and the other end of the other support rod 38 is rotatably mounted on the second slider 37.

[0037] In detail, the frame 30 mainly plays a supporting role. The motor 32 can drive a support shaft 31 to rotate through the transmission wheel 33, and the support shaft 31 drives the power wheel 9 thereon to rotate, thereby driving the power unit 2 to operate. The support structure can provide auxiliary support for the material barrel 1. The two support rods 38 between the second connecting ring 34 and the guide rail 35 form an X shape. When the material barrel 1 performs a circular translation motion, the distance and relative position between the material barrel 1 and the guide rail 35 change. At this time, the second connecting ring 34 will push the slide 36 to slide on the guide rail 35 and the second slider 37 to slide on the slide 36 through the two support rods 38, thereby realizing dynamic support for the material barrel 1.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
