DETAILED DESCRIPTION

[0024] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described herein are only used for illustrating and explaining the utility model, and are not used for limiting the utility model.

[0025] Embodiment: as Figure 1 and Figure 4As shown, this utility model discloses a solid-liquid separation and screening device for chemical production, comprising an outer separation cylinder 1 and an inner separation cylinder 2 connected to the upper end of the outer separation cylinder 1 via a rotating shaft. A reduction motor 3 is installed at the top of the outer separation cylinder 1 to drive the inner separation cylinder 2 to rotate. The inner separation cylinder 2 has several separation holes 4. The bottom end of the inner separation cylinder 2 is provided with a liftable sealing bottom cover plate 5. The bottom end of the inner separation cylinder 2 is provided with a connecting discharge cylinder 6 that protrudes outwards and has a V-shaped cross-section. The bottom end of the connecting discharge cylinder 6 is provided with a connecting cylinder 7, and the bottom end of the connecting cylinder 7 is provided with a rotating groove 24. A rotating ring 25 is slidably disposed inside the rotating tank 24. Ball bearings 26 are embedded in the inner wall of the rotating ring 25. A funnel-shaped discharge hopper 8, connected to the outer separating cylinder 1, is located at the bottom of the rotating ring 25. A spiral discharge plate 9, connected to the inner wall of the outer separating cylinder 1, is located on the outer wall of the connecting cylinder 7. Feeding components 10 are located at the top of both the inner separating cylinder 2 and the outer separating cylinder 1. During solid-liquid separation, the output shaft of the reduction motor 3 drives the inner separating cylinder 2 to rotate. The centrifugal force generated by the rotation of the inner separating cylinder 2 separates the liquid from several separation holes 4, leaving the solid. Inside the inner separator cylinder 2, the separated liquid, guided by the inner wall of the outer separator cylinder 1, the outer wall of the connecting discharge cylinder 6, and the spiral discharge plate 9, undergoes separation. After the liquid separation is complete, the sealing bottom cover plate 5 moves downward to the middle of the connecting discharge cylinder 6, leaving a discharge gap between the sealing bottom cover plate 5 and the connecting discharge cylinder 6, allowing for discharge. The output shaft of the reduction motor 3 continues to drive the inner separator cylinder 2 to rotate, which in turn drives the connecting discharge cylinder 6 to rotate. The connecting discharge cylinder 6 then drives the connecting cylinder 7 to rotate. The discharge hopper 8 and the connecting cylinder 7 pass through the rotating groove 24 and the rotating ring 25. The rotating connection and the design of the ball bearing 26 improve the smoothness of the rotation of the connecting cylinder 7. At the same time, the sealing bottom cover plate 5 rotates synchronously. Under the action of centrifugal force, the material on the sealing bottom cover plate 5 can be thrown out. Under the guidance of the inner wall of the connecting discharge cylinder 6, the solid material can be discharged from the connecting cylinder 7 and the discharge hopper 8, which facilitates the solid-liquid separation of chemical materials and the discharge of the separated solids and liquids. This avoids the current situation where the liquid is easy to discharge but the solid material is inconvenient to discharge, which increases labor intensity and affects the separation efficiency, and further improves the material separation efficiency.

[0026] Specifically, such as Figure 2 As shown, the cross-section of the sealing bottom cover plate 5 is trapezoidal, and the bottom end of the separating inner cylinder 2 is provided with a guide slope 11 that matches the outer wall of the sealing bottom cover plate 5. A sealing gasket 12 is embedded in the guide slope 11 to facilitate the sealing bottom cover plate 5 to abut against the guide slope 11 of the bottom wall of the separating inner cylinder 2. With the cooperation of the sealing gasket 12, the sealing performance at the connection between the sealing bottom cover plate 5 and the separating inner cylinder 2 is improved, and liquid is prevented from flowing out from the connection between the sealing bottom cover plate 5 and the separating inner cylinder 2.

[0027] Specifically, such as Figure 3As shown, the bottom end of the connecting cylinder 7 is provided with a mounting plate 13, and the middle part of the mounting plate 13 is provided with a hydraulic cylinder 14 vertically upward and connected with the sealing bottom cover plate 5, and the hydraulic cylinder 14 can drive the sealing bottom cover plate 5 to lift, so as to discharge the separated solid materials.

[0028] Wherein, the mounting plate 13 is provided with a telescopic sleeve 15 sleeved outside the hydraulic cylinder 14, which improves the stability of the lifting of the sealing bottom cover plate 5, and avoids the contact of the solid materials with the hydraulic cylinder 14 to affect the practicality of the hydraulic cylinder 14.

[0029] Wherein, the top end of the mounting plate 13 is provided with a triangular connecting plate 16 connected with the telescopic sleeve 15 and the inner wall of the connecting cylinder 7, which avoids the solid materials falling on the mounting plate 13.

[0030] Specifically, as shown in Figure 1 and Figure 5 The feeding assembly 10 comprises a feeding port 17 opened at the top end of the separation inner cylinder 2 and the separation outer cylinder 1, and the feeding port 17 of the separation outer cylinder 1 is provided with a feeding hopper 18 and a protective cover 19 covering the outside of the speed reducer 3, which facilitates the addition of the materials to be separated into the inside of the separation inner cylinder 2.

[0031] Wherein, the bottom end of the separation outer cylinder 1 is provided with a liquid discharge hopper 20 located directly below the lowest part of the spiral liquid discharge plate 9, and the top end of the liquid discharge hopper 20 is provided with a material guide pipe 21 connected with the lowest end of the spiral liquid discharge plate 9, and the bottom part of the separation outer cylinder 1 is provided with a liquid collecting cylinder 22 located directly below the liquid discharge hopper 20 and a material collecting cylinder 23 located directly below the discharge hopper 8, which facilitates the collection of the liquid and solid materials.

[0032] In operation, when the solid-liquid separation screening device for chemical production separates solid and liquid, the output shaft of the speed reducer 3 drives the separation inner cylinder 2 to rotate, and the centrifugal force generated by the rotation of the separation inner cylinder 2 separates the liquid from the plurality of separation holes 4, and the solid remains inside the separation inner cylinder 2. Under the guiding action of the inner wall of the separation outer cylinder 1, the outer wall of the connecting discharge cylinder 6 and the spiral discharge plate 9, after the liquid separation is completed, the sealing bottom cover plate 5 moves downward to the middle part in the connecting discharge cylinder 6, and a discharge gap is left between the sealing bottom cover plate 5 and the connecting discharge cylinder 6, so that the discharge can be carried out. The output shaft of the speed reducer 3 continues to drive the separation inner cylinder 2 to rotate, the separation inner cylinder 2 drives the connecting discharge cylinder 6 to rotate, the connecting discharge cylinder 6 drives the connecting cylinder 7 to rotate, the discharge hopper 8 and the connecting cylinder 7 are connected through the rotating groove 24 and the rotating ring 25, the design of the ball 26 improves the smoothness of the rotation of the connecting cylinder 7, and the sealing bottom cover plate 5 rotates synchronously. Under the action of the centrifugal force, the material on the sealing bottom cover plate 5 can be thrown out, and under the guiding action of the inner wall of the connecting discharge cylinder 6, the solid material can be discharged from the connecting cylinder 7 and the discharge hopper 8. The solid-liquid separation of the chemical material is facilitated, and the separated solid and liquid are also facilitated to be discharged. The labor intensity is increased, the separation efficiency is affected, and the separation efficiency of the material is further improved.

[0033] Finally, it should be noted that: the above only preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for those skilled in the art, it can still be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
