Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0016] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0017] like Figures 1-6The diagram shown illustrates the structure of a raw material screening device for chemical production according to an embodiment of the present invention. The device includes a cylinder 1, a screen plate 2, a longitudinal rotating shaft 5, a ring drive mechanism 200, an automatic feeding mechanism 300, and a rapid screening mechanism 400. The screen plate 2 is slidably arranged inside the cylinder 1, and its surface is provided with a plurality of evenly distributed screen holes 3. The longitudinal rotating shaft 5 is installed in the middle of the screen plate 2 and is driven by an external motor. An anti-clogging mechanism 100 is provided at the bottom end of the longitudinal rotating shaft 5 and is rotatably mounted on the cylinder 1. The top of the screen plate 2 abuts against the bottom surface of the screen plate 2, so as to push the screen plate 2 to shake along the cylinder 1 when the longitudinal rotating shaft 5 rotates; the annular drive mechanism 200 is arranged on the outside of the cylinder 1, and the top of the annular drive mechanism 200 is fixedly connected to the longitudinal rotating shaft 5; the automatic feeding mechanism 300 is installed on the movable end of the annular drive mechanism 200, and the automatic feeding mechanism 300 rotates as it moves with the annular drive mechanism 200; the rapid screening mechanism 400 is arranged at the bottom end of the screen plate 2, and the top of the rapid screening mechanism 400 abuts against the anti-clogging mechanism 100, so as to move synchronously when pushing the screen plate 2 to shake.

[0018] The raw material screening device for chemical production provided in this application can, in actual use, evenly spread the chemical raw materials remaining on the upper surface of the screen plate 2 through the set ring drive mechanism 200 and automatic feeding mechanism 300, and accelerate the raw materials to fall down through the screen holes 3, thereby avoiding the situation of raw materials clogging the screen holes 3. At the same time, it can perform multi-stage screening of chemical raw materials as needed, and quickly screen them according to the volume of the chemical raw materials.

[0019] In one embodiment of the present invention, the upper surface of the screen plate 2 is provided with a protrusion 4, the protrusion 4 covers the groove provided on the inner wall of the cylinder 1, the protrusion 4 rises and falls synchronously with the screen plate 2, and is used to prevent the raw material from being embedded in the elastic support member 11.

[0020] like Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the anti-clogging mechanism 100 includes a transverse rotating shaft 7 rotatably mounted on the cylinder 1, a turntable 9 arranged on the transverse rotating shaft 7, and an elastic support member 11 disposed between the cylinder 1 and the screen plate 2. Support rods 12 are symmetrically installed on the inner wall of the cylinder 1, and a fixing frame 6 is installed at the top of the support rods 12. The fixing frame 6 is rotatably connected to the transverse rotating shaft 7. The bottom end of the longitudinal rotating shaft 5 is located inside the fixed frame 6, and the longitudinal rotating shaft 5 is also connected to the transverse rotating shaft 7 through a bevel gear set 8. The outer surface of the turntable 9 is provided with multiple smooth arc surfaces and arc-shaped grooves 10, and the smooth arc surfaces and arc-shaped grooves 10 are arranged alternately.

[0021] In the specific implementation of this embodiment, the longitudinal rotating shaft 5 rotates under the drive of an external motor. The longitudinal rotating shaft 5 causes the transverse rotating shaft 7 to rotate simultaneously along the cylinder 1 and the fixed frame 6 through the set bevel gear set 8. The turntable 9 moves synchronously with the transverse rotating shaft 7. When the smooth arc surface of the turntable 9 contacts the screen plate 2, the screen plate 2 itself remains stationary. When the arc groove 10 begins to contact the screen plate 2, the elastic support member 11 deforms and pushes the screen plate 2 downward. The turntable 9 continues to rotate, repeating the above process. The screen plate 2 shakes back and forth in the height direction, which can effectively prevent the raw materials used in chemical production from clogging in the screen holes 3.

[0022] like Figure 1 , Figure 4 and Figure 5 As shown, in another preferred embodiment of the present invention, the ring drive mechanism 200 includes a plurality of fixed rods 13 fixedly mounted on the longitudinal rotating shaft 5, an arc-shaped rod 14 arranged at the end of the fixed rod 13, and a movable block 15 connecting adjacent arc-shaped rods 14. One side of the movable block 15 is slidably connected to the annular guide groove 16 provided on the outer surface of the cylinder 1; The movable block 15 is also equipped with a positioning seat 17, and a drive shaft 18 is rotatably arranged on the positioning seat 17.

[0023] In the specific implementation of this embodiment, when the longitudinal rotating shaft 5 rotates, the fixed rod 13, the arc rod 14 and the movable block 15 move synchronously, and the inner side of the movable block 15 slides along the annular guide groove 16 provided on the outer side of the cylinder 1, thereby preventing it from falling off. At the same time, the positioning seat 17 and the transmission shaft 18 rotate in the horizontal plane with the longitudinal rotating shaft 5.

[0024] like Figure 5 As shown, in another preferred embodiment of the present invention, the automatic feeding mechanism 300 includes a drive wheel 19 fixedly mounted on the transmission shaft 18; The upper surface of the cylinder 1 is provided with a groove 20, and an annular toothed ring 21 is installed in the groove 20, and the annular toothed ring 21 meshes with the drive wheel 19.

[0025] In the specific implementation of this embodiment, the accompanying drawings are used as a reference. Figure 5 Based on the reference, the movable block 15, the positioning seat 17 and the transmission shaft 18 rotate in the horizontal plane, and the drive wheel 19 moves synchronously. At the same time, since the drive wheel 19 meshes with the ring gear 21, the transmission shaft 18 also rotates along the fixed axis of the positioning seat 17 when rotating in the horizontal plane.

[0026] like Figure 1 and Figure 6 As shown, in another preferred embodiment of the present invention, the transmission shafts 18 are arranged in the same number as the fixed rods 13, and the multiple transmission shafts 18 are sequentially equipped with levers 24, 25, 22 and 23. Among them, lever 3 24, lever 4 25, lever 1 22 and lever 2 23 are all arranged at equal intervals; The distances between levers 24, 25, 22, and 23 and the longitudinal axis 5 increase linearly.

[0027] In the specific implementation of this embodiment, when the drive shaft 18 revolves and rotates, the lever 1 22, lever 23, lever 3 24 and lever 4 25 rotate synchronously. Since the movement trajectories of the lever 1 22, lever 23, lever 3 24 and lever 4 25 are all circles with different diameters, they can continuously move the chemical raw materials during movement and spread the raw materials evenly, thereby preventing the raw materials on the screen plate 1 2 from piling up together.

[0028] like Figure 2 and Figure 3 As shown, in another preferred embodiment of the present invention, the rapid screening mechanism 400 includes a vertical rod 26 slidably mounted on a support rod 12 and a screen plate 27 arranged at the bottom end of the vertical rod 26; A retaining ring 28 is installed on the vertical rod 26, and the top of the retaining ring 28 is connected to the support rod 12; The top end of the vertical rod 26 abuts against the turntable 9, and the bottom end of the vertical rod 26 is slidably connected to the transverse ball groove provided on the sieve plate 27.

[0029] In the specific implementation of this embodiment, the accompanying drawings are used as a reference. Figure 1 Based on this, when the top of the vertical rod 26 enters the arc-shaped groove 10 from the outer arc surface of the turntable 9, the elastic support member 29 pulls the retaining ring 28 upward, and the retaining ring 28 drives the bottom screen plate 27 to move synchronously. In addition, if the tops of the vertical rods 26 on both sides are located in the arc-shaped grooves 10 at different heights, one side of the screen plate 27 moves upward and the other side of the screen plate 27 moves downward, causing the two ends of the screen plate 27 to warp in opposite directions, so as to accelerate the screening of chemical raw materials. When multi-stage screening of chemical raw materials is required, the dimensions of the vertical rod 26 can be extended to arrange multiple sets of sieve plates 27, and the aperture of the sieve plates 27 can be gradually changed from top to bottom to complete the step-by-step screening of chemical raw materials.

[0030] In summary, during use, the raw materials for chemical production are placed on the screen plate 2. The longitudinal rotating shaft 5 rotates under the drive of an external motor. The longitudinal rotating shaft 5, through the set bevel gear set 8, causes the transverse rotating shaft 7 to rotate simultaneously along the cylinder 1 and the fixed frame 6. The turntable 9 moves synchronously with the transverse rotating shaft 7. When the smooth arc surface of the turntable 9 contacts the screen plate 2, the screen plate 2 itself remains stationary. When the arc groove 10 begins to contact the screen plate 2, the elastic support member 11 deforms and pushes the screen plate 2 downward. The turntable 9 continues to rotate, repeating the above process. The screen plate 2 vibrates back and forth in the height direction, which can effectively prevent the raw materials for chemical production from clogging in the screen holes 3. The fixed rod 13, the arc rod 14, and the movable block 15 move synchronously with the longitudinal rotating shaft 5. The movable block 15 also slides along the annular guide groove 16 set on the outside of the cylinder 1, thereby preventing it from falling off. At the same time, the positioning seat 17 and the transmission shaft 18 rotate in the horizontal plane with the longitudinal rotating shaft 5. Wheel 19 meshes with ring gear 21, so when the drive shaft 18 rotates in the horizontal plane, it also rotates along the fixed axis of the positioning seat 17. The levers 1-22, 23-24, 25-25 rotate synchronously, continuously agitating the chemical raw materials during movement and spreading them evenly, thus preventing the raw materials on the screen plate 2 from piling up. After screening, the raw materials fall downwards onto the screen plate 27. When the top of the vertical rod 26 enters the arc-shaped groove 10 from the outer arc surface of the turntable 9, the elastic support... When component 29 pulls the retaining ring 28 upward, the retaining ring 28 drives the bottom screen plate 27 to move synchronously, so as to accelerate the secondary screening of chemical raw materials. This application can use the set ring drive mechanism 200 and automatic feeding mechanism 300 to evenly spread the chemical raw materials remaining on the upper surface of the screen plate 2 and accelerate the raw materials to fall down through the screen holes 3, thereby avoiding the situation of raw materials clogging the screen holes 3. At the same time, it can perform multi-stage screening of chemical raw materials as needed and quickly screen them according to the volume of the chemical raw materials.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
