Description

Technical Field

[0001] This invention relates to the field of chemical raw material processing technology, and more specifically, to an automated screening and impurity removal device for chemical raw materials. Background Technology

[0002] During the production, processing, storage, and transportation of chemical raw materials, it is often unavoidable for solid particles of different sizes to become mixed in. Lightweight floating impurities or dust may also be present. These impurities not only affect the uniformity and purity of the material but may also adversely impact the precision of subsequent formulations, reaction stability, and the quality of the final product. Therefore, before entering subsequent production or use stages, chemical raw materials typically require screening and impurity removal. By separating particles of different sizes and removing lightweight floating matter, the purity and stability of the material are effectively improved, ensuring the reliability of its subsequent processing performance and usage effects.

[0003] Existing screening equipment mostly adopts a single-stage screening structure. In actual operation, it often suffers from problems such as a single screening path and insufficient grading effect. This makes it difficult to fully separate some fine particulate impurities and remove light floating matter simultaneously and effectively, thus affecting the overall screening accuracy and material purity. At the same time, under long-term operation, the screen is prone to clogging due to material accumulation, which not only reduces screening efficiency but also affects the ability to operate continuously. Furthermore, the tension of the screen in traditional structures is not easy to control stably, and problems such as slackness or uneven stress are prone to occur, resulting in fluctuations in screening effect and making the screen disassembly and maintenance process more cumbersome.

[0004] Therefore, we have made improvements to this and proposed an automated screening and impurity removal device for chemical raw materials. Summary of the Invention

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0020] An automated screening and impurity removal device for chemical raw materials includes a frame 1 for supporting the upper part, a power mechanism 2 for providing power to the whole device is provided on the lower side of the inner cavity of the frame 1, a primary screening mechanism 3 for primary screening of chemical raw materials is provided on the upper side of the frame 1, the primary screening mechanism 3 includes a tensioning component 36 for adjusting the tension of the screen and a clamping component 37 for easy disassembly of the screen, both the tensioning component 36 and the clamping component 37 are provided on the upper side of the frame 1, a secondary screening mechanism 4 for secondary screening of chemical raw materials is provided at the lower end of the primary screening mechanism 3, and the secondary screening mechanism 4 is provided on the inner side of the frame 1, and an air jet component 5 for removing light floating matter in chemical raw materials is provided on one side of the frame 1. Chemical raw materials first enter the overall system under the support of the frame 1. Driven by the power mechanism 2 located on the lower side of the inner cavity of the frame 1, the power motor 21 drives the drive pulley 22 to rotate. Through the transmission belt 26 and the driven pulley 25, the rotating shaft 24 rotates. This power is then transmitted to the primary screening mechanism 3 and the secondary screening mechanism 4 via the transmission link 27, causing the primary screening support frame 33 and the secondary screening plate 43 to reciprocate synchronously. Under the action of the primary screening mechanism 3, the raw materials fall onto the surface of the primary screen 38 for preliminary screening. During the primary screening process, the tension of the primary screen 38 is adjusted by the tensioning component 36 to ensure... To ensure screening stability, the primary screen 38 is clamped and fixed by the clamping component 37, facilitating quick disassembly and replacement of the primary screen 38. The material after primary screening continues to enter the secondary screening frame 41 in the secondary screening mechanism 4. Supported by the support roller 42, the secondary screening plate 43 is driven by the power mechanism 2 to vibrate and perform secondary fine screening. During the screening process, the jet assembly 5 set on one side of the frame 1 delivers airflow through the blower pipe 52 to the high-pressure outlet 53 via the high-pressure blower 51, and acts between the primary screen 38 and the secondary screening plate 43 to blow away and remove light floating matter in the material, thereby achieving multi-stage screening of chemical raw materials.

[0021] Furthermore, the power mechanism 2 includes a power motor 21, which is fixedly connected to the lower side of the inner cavity of the frame 1. The output end of the power motor 21 is fixedly connected to a drive pulley 22. A bracket 23 is fixedly connected to one side of the upper end of the frame 1. A rotating shaft 24 is rotatably connected to the upper end of the bracket 23. A driven pulley 25 is fixedly connected to the outer surface of one side of the rotating shaft 24. A transmission belt 26 is rotatably connected to the inner cavity of the outer surface of the driven pulley 25. The driven pulley 25 is rotatably connected to the drive pulley 22 through the transmission belt 26. A transmission connecting rod 27 is fixedly connected to the outer surface of the rotating shaft 24 away from the driven pulley 25. The power motor 21 is fixedly installed on the lower side of the inner cavity of the frame 1. Its output end drives the drive pulley 22 to rotate at high speed. The drive pulley 22 is connected to the driven pulley 25 through the transmission belt 26 to form a belt drive connection, thereby transmitting power from the power motor 21 to the driven pulley 25. The driven pulley 25 rotates synchronously under the drive of the transmission belt 26, and drives the rotating shaft 24, which is fixedly connected to it on the same axis, to rotate. The rotating shaft 24 operates stably under the rotational support of the bracket 23, and further transmits the rotational power to the transmission link 27 fixed on the outer surface of the other side of the rotating shaft 24, so that the transmission link 27 rotates periodically or reciprocates with the rotating shaft 24, thereby realizing the continuous power transmission process from the power motor 21 to the transmission link 27.

[0022] Furthermore, the primary screening mechanism 3 also includes four sets of symmetrically arranged L-shaped support rods 31. The four sets of L-shaped support rods 31 are fixedly connected to one side of the upper end of the frame 1. The upper ends of the four sets of symmetrically arranged L-shaped support rods 31 are all fixedly connected to dampers 32. The upper ends of the dampers 32 are fixedly connected to primary screening support frames 33. The side of the primary screening support frame 33 closest to the power mechanism 2 is fixedly connected to a first hinge 34. The inner cavity of the first hinge 34 is rotatably connected to a first screening moving link 35, and the first hinge 34 is rotatably connected to the transmission link 27 through the first screening moving link 35. Four sets of L-shaped support rods 31 are fixedly connected to one side of the upper end of the frame 1, forming a basic support frame for the upper structure. The dampers 32 fixedly connected to the upper ends of the four sets of L-shaped support rods 31 are used to buffer and stabilize the force and vibration of the primary screening support frame 33, so that the primary screening support frame 33 maintains a stable screening motion when subjected to power. The first hinge 34 fixedly connected to one side of the primary screening support frame 33 forms a rotating connection base with the primary screening support frame 33. One end of the first screening moving link 35 is rotatably connected to the inner cavity of the first hinge 34, and the other end is rotatably connected to the transmission link 27. When the transmission link 27 generates periodic motion under the drive of the power mechanism 2, the first hinge 34 is driven to reciprocate through the first screening moving link 35, so that the primary screening support frame 33 generates a stable screening motion under the limiting and buffering effect of the four sets of L-shaped support rods 31 and the dampers 32.

[0023] Furthermore, the tensioning assembly 36 includes a first connecting post 3601, which is fixedly connected to one side of the upper end of the primary screening support frame 33. An electric push rod 3602 is fixedly connected to the side of the first connecting post 3601 away from the primary screening support frame 33. A telescopic rod 3603 is fixedly connected to the output end of the electric push rod 3602. A bearing 3604 is fixedly connected to one side of the telescopic rod 3603. A second connecting post 3605 is fixedly connected to the inner cavity of the bearing 3604. A limit ring 3606 is fixedly connected to the outer surface of the second connecting post 3605 away from the bearing 3604. The first connecting column 3601 is fixedly connected to one side of the upper end of the primary screening support frame 33, providing an installation base for the overall tension adjustment structure. The electric push rod 3602 is fixedly connected to the side of the first connecting column 3601 away from the primary screening support frame 33, and drives the telescopic rod 3603 to perform linear telescopic movement through its output end. When the telescopic rod 3603 reciprocates under the action of the electric push rod 3602, it achieves rotation and force transition through the bearing 3604 fixedly connected to one side of it, so that the second connecting column 3605 maintains a stable position under the support of the inner cavity of the bearing 3604. At the same time, the second connecting column 3605, the bearing 3604 and the limiting ring 3606 work together to keep the axial movement stable under the restriction of the limiting ring 3606, thereby achieving a stable adjustment base and force control effect for the tension structure on the side of the primary screening support frame 33.

[0024] Furthermore, a third connecting post 3607 is fixedly connected to the outer surface of the second connecting post 3605. The third connecting post 3607 is U-shaped with the telescopic rod 3603 through the second connecting post 3605 and the bearing 3604. The second connecting column 3605 and the bearing 3604 form a rotational support relationship. The third connecting column 3607 is fixedly connected to the outer surface of the second connecting column 3605 and forms a rigid extension structure with the second connecting column 3605. Based on the bearing 3604 providing rotational support and force transition on one side of the telescopic rod 3603, the third connecting column 3607 forms an extension arrangement of the lateral structure of the telescopic rod 3603 through the fixed connection with the second connecting column 3605, so that the overall connection structure has a U-shaped spatial distribution relationship, thereby forming a stable spatial force-bearing frame with the telescopic rod 3603.

[0025] Furthermore, the clamping assembly 37 includes a U-shaped support column 3701, which is fixedly connected to the end of the third connecting column 3607 away from the second connecting column 3605. A micro motor 3702 is fixedly connected to the end of the U-shaped support column 3701 away from the third connecting column 3607. A lead screw 3703 is fixedly connected to the output end of the micro motor 3702. A guide block 3704 is threaded onto the outer surface of the lead screw 3703. The U-shaped support column 3701 is fixedly connected to the end of the third connecting column 3607 away from the second connecting column 3605, providing an installation and support base for the overall clamping and adjustment mechanism; the micro motor 3702 is fixedly connected to the upper end of the U-shaped support column 3701, and drives the lead screw 3703 to generate rotational motion through the output end; when the lead screw 3703 rotates continuously under the drive of the micro motor 3702, its outer surface and the guide block 3704 form a helical transmission through a threaded connection, so that the guide block 3704 reciprocates along the axial direction under the rotation of the lead screw 3703, thereby realizing the driving and adjustment effect of the clamping assembly 37 execution end, and ensuring stable control of the clamping action.

[0026] Furthermore, a first clamping link 3705 is rotatably connected to the outer surface of the guide block 3704, and a transverse slider 3706 is rotatably connected to the side of the first clamping link 3705 away from the guide block 3704. A clamping guide shaft 3707 is slidably connected to the inner cavity of the transverse slider 3706, and the clamping guide shaft 3707 is fixedly connected to the inner cavity of the U-shaped support rod away from the third connecting column 3607. The guide block 3704 and the first clamping link 3705 are rotatably connected to form an adjustable transmission relationship, allowing the guide block 3704 to drive the first clamping link 3705 to swing and adjust when the lead screw 3703 drives the first clamping link 3705 to move. The other end of the first clamping link 3705 is rotatably connected to the transverse slider 3706, so that the swinging motion of the first clamping link 3705 is converted into the guiding motion of the transverse slider 3706 in the horizontal direction. The transverse slider 3706 is constrained by the clamping guide shaft 3707. The lateral slider 3706 slides stably along the inner cavity of the clamping guide shaft 3707, ensuring that its movement trajectory remains linear. Simultaneously, the clamping guide shaft 3707 is fixedly connected to the inner cavity of the U-shaped support rod on the side away from the third connecting column 3607, providing a stable guiding support foundation for the lateral slider 3706. Thus, the entire clamping transmission process achieves stable clamping guidance through the coordinated action of the guide block 3704, the first clamping connecting rod 3705, the lateral slider 3706, the clamping guide shaft 3707, and the U-shaped support rod.

[0027] Furthermore, a second clamping link 3708 is rotatably connected to the side of the transverse slider 3706 away from the first clamping link 3705. A spring 3709 is fixedly connected to the inner cavity of the second clamping link 3708. A gripper 3710 is rotatably connected to the side of the second clamping link 3708 away from the transverse slider 3706. Two sets of grippers 3710 are symmetrically arranged. A primary screen 38 is detachably connected between the two sets of symmetrically arranged grippers. Tensioning components 36 and clamping components 37 are symmetrically arranged at the four diagonals of the primary screen 38. The transverse slider 3706 is rotatably connected to the first clamping link 3705, allowing the swing motion of the first clamping link 3705 under the drive of the guide block 3704 to be transmitted to the transverse slider 3706. The transverse slider 3706 forms a sliding fit with the clamping guide shaft 3707, allowing the transverse slider 3706 to perform stable linear reciprocating motion along the clamping guide shaft 3707 under the drive of the first clamping link 3705. The clamping guide shaft 3707 is fixedly connected to the inner cavity of the U-shaped support rod on the side away from the third connecting post 3607, providing guidance and limiting support for the transverse slider 3706. At the same time, the second clamping link 3708 is fixedly connected to the transverse slider 3706 away from the first clamping link 3705. On one side of 05, the force is transmitted through a rotational connection with the transverse slider 3706. The spring 3709 is set in the inner cavity of the second clamping link 3708 to provide elastic buffer and return support during the clamping movement. The gripper 3710 is set on the side of the second clamping link 3708 away from the transverse slider 3706 through a rotational connection, and is driven by the second clamping link 3708 to generate a clamping action. The two sets of symmetrically arranged grippers 3710 cooperate with each other to clamp and fix the primary screen 38. The primary screen 38 is detachably connected through the clamping assembly 37, so that with the cooperation of the tensioning assembly 36 and the clamping assembly 37 at the four diagonal points, the primary screen 38 can be stably clamped and tensioned and positioned.

[0028] Furthermore, the secondary screening mechanism 4 includes a secondary screening frame 41, which is fixedly connected to the upper side of the inner cavity of the frame 1 and is located below the primary screening screen 38. A support roller 42 is rotatably connected to the upper side of the inner cavity of the secondary screening frame 41, and a secondary screening plate 43 is rotatably connected to the upper side of the support roller 42. A second hinge 44 is fixedly connected to the side of the secondary screening plate 43 near the power mechanism 2. A second screening moving link 45 is rotatably connected to the inner cavity of the second hinge 44, and the side of the second screening moving link 45 away from the second hinge 44 is rotatably connected to the transmission link 27. The secondary screening frame 41 is fixedly connected to the upper side of the inner cavity of the frame 1 and located below the primary screening screen 38, providing installation and bearing space for the secondary screening process; the support roller 42 is rotatably connected to the upper side of the inner cavity of the secondary screening frame 41, providing rolling support to the upper side of the secondary screening plate 43, so that the secondary screening plate 43 maintains a stable support and guiding state during movement; the secondary screening plate 43 moves relative to the support roller 42, and through the fixed connection with the second hinge 44, the motion transmitted by the power mechanism 2 is converted into the vibrating screening action of the secondary screening plate 43; the second hinge 44 is rotatably connected to the second screening moving link 45, so that the second screening moving link 45 can swing with the secondary screening plate 43; the side of the second screening moving link 45 away from the second hinge 44 is rotatably connected to the transmission link 27, thereby stably transmitting the driving force of the transmission link 27 to the secondary screening plate 43, driving the secondary screening plate 43 to achieve continuous vibration within the secondary screening frame 41.

[0029] Furthermore, the jet assembly 5 includes a high-pressure blower 51, which is fixedly connected to the side of the power motor 21 away from the drive pulley 22, and the high-pressure blower 51 and the power motor 21 are electrically connected. The output end of the high-pressure blower 51 is fixedly connected to a blower pipe 52, and the side of the blower pipe 52 away from the high-pressure blower 51 is fixedly connected to a high-pressure air outlet 53, which is located between the primary screen 38 and the secondary screen plate 43. The high-pressure blower 51 is fixedly connected to the side of the power motor 21 away from the drive pulley 22 and is electrically connected to the power motor 21, so that the high-pressure blower 51 can start synchronously and obtain electric drive when the power motor 21 is running. The high-pressure blower 51 is fixedly connected to the blower pipe 52 through the output end, and delivers the generated high-pressure airflow into the blower pipe 52. The side of the blower pipe 52 away from the high-pressure blower 51 is fixedly connected to a high-pressure air outlet 53, so that the airflow is stably delivered through the blower pipe 52 and directionally sprayed out from the high-pressure air outlet 53. The high-pressure air outlet 53 is set between the primary screen 38 and the secondary screen plate 43, so that the sprayed high-pressure airflow acts on the material area between the primary screen 38 and the secondary screen plate 43, thereby blowing away and separating light floating objects and achieving an auxiliary impurity removal effect.
