Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 3 , an embodiment provided by the present invention: a new type of vibrating structure dewatering screen, including a sieve box 100. At both ends of the vibrating beam above the sieve box 100, there is an outer auxiliary beam and a side plate respectively. The vibrating beam, the outer auxiliary beam and the side plate are clamped together with high-strength screws. A vibrator 200 is fixedly arranged directly above the side plate. The vibrator 200 is arranged above the side plate and can directly drive the vibration above the entire sieve box 100 to reduce the intermediate transmission loss. A secondary beam is fixedly provided on the side of the sieve box 100 corresponding to the vibrating beam. The vibrating beam and the secondary beam are uniformly precision machined to ensure that the two surfaces are in the same plane, and the secondary beam is added to improve the stability. A sieve plate 300 is arranged at the bottom of the inner cavity of the sieve box 100. The sieve plate 300 is a porous structure. A plurality of sieve bars 400 are arranged on the sieve plate 300. The sieve plate 300 and the plurality of sieve bars 400 are integrally cast. The sieve plate 300 and the plurality of sieve bars 400 form a wavy sieve surface. The material to be dehydrated enters the sieve box 100. When the vibrator 200 works, the sieve box 100 vibrates, and the sieve plate 300 vibrates accordingly. The material falling on the sieve plate 300 is quickly dispersed under the vibration action. Fine particles and moisture fall through the holes of the sieve plate 300, while larger particles remain on the sieve plate 300.

[0021] Two brackets 500 are symmetrically arranged at the sieve box 100. The brackets 500 are in a Y shape. A cross plate A 600 and a cross plate B 700 are respectively arranged between the two brackets 500. The two ends of the cross plate A 600 and the cross plate B 700 are respectively fixedly connected to the extended ends of the two brackets 500. The cross plate A 600 and the cross plate B 700 are symmetric with respect to the bracket 500. A blanking plate A 800 is arranged on the cross plate A 600. The blanking section of the blanking plate A 800 is inclined. An oil cylinder 1000 is fixedly arranged at the bottom of the cross plate B 700. An installation block is arranged on the cylinder body of the oil cylinder 1000. The installation block on the cylinder body is fixedly connected to the installation block at the bottom of the cross plate B 700 through bolts and nuts. An inclined blanking plate B 900 is arranged at the outer end of the push rod of the oil cylinder 1000. The blanking plate B 900 and the blanking section of the blanking plate A 800 form a feeding area. The bottom surface of the inclined end of the blanking plate B 900 is in contact and cooperation with the inclined surface of the blanking section of the blanking plate A 800. When the bottom surface of the inclined end of the blanking plate B 900 is in contact with the inclined surface of the blanking section of the blanking plate A 800, the bottom of the feeding area formed by the blanking plate B 900 and the blanking section of the blanking plate A 800 is closed and no further blanking will occur. The blanking plate B 900 can move relative to the blanking plate A 800 under the action of the oil cylinder 1000. Materials enter the sieve box 100 through the opening at the bottom of the feeding area formed by the blanking plate B 900 and the blanking section of the blanking plate A 800 for separation.

[0022] By arranging the bracket 500, the cross plate A 600, the cross plate B 700, the blanking plate A 800, the blanking plate B 900 and the oil cylinder 1000, the present invention has the advantages that the opening degree of the discharge port of the feeding area formed by the blanking plate B 900 and the blanking section of the blanking plate A 800 can be adjusted, the amount of materials entering the sieve box 100 can be controlled, and the separation effect can be optimized, solving the problem that for the same feeding amount, there is a problem of exceeding the processing capacity of the sieve surface for different materials.

[0023] Please refer to Figure 1 and Figure 13 , an embodiment provided by the present invention: a new type of vibration structure dewatering sieve, the sieve bars 400 are in a triangular structure, and a plurality of sieve slots are arranged on the sieve bars 400. The length direction of the sieve slots is along the side line direction of the triangular cross section, increasing the total sieve slot area, improving the opening rate, improving the processing capacity, and the sieve slots are not easily blocked by sticky materials, etc.

[0024] Please refer to Figures 2 to 7, an embodiment provided by the present invention: a new type of vibrating structure dehydration screen. An inclined groove 601 is provided on the cross plate A600. The L-shaped connecting section of the blanking plate A800 is clamped and matched with the cross plate A600. The top of the blanking section of the blanking plate A800 is clamped and matched with the inclined groove 601. After the L-shaped connecting section of the blanking plate A800 is butted with the cross plate A600, it remains stable, and the L-shaped connecting section of the blanking plate A800 can be detached from the cross plate A600. The outer end of the push rod of the oil cylinder 1000 is connected to the blanking plate B900 through a connecting structure 1100. The connecting structure 1100 includes a connecting column 1101, a connecting rod 1102 and a screw sleeve 1103. The connecting column 1101 is fixedly connected to the blanking plate B900. The connecting rod 1102 is fixedly connected to the outer end of the push rod of the oil cylinder 1000. One end of the screw sleeve 1103 is provided with an opening for passing through the connecting rod 1102. The threaded hole at the other end of the screw sleeve 1103 is threadedly connected to the threaded groove on the connecting column 1101. A convex head is provided at the outer end of the connecting rod 1102, and the convex head is inserted and matched with the hole between the opening at one end and the threaded hole at the other end of the screw sleeve 1103. A slot 1105 is provided at the outer end of the connecting column 1101. An insertion column 1104 is fixedly provided at the outer end of the convex head of the connecting rod 1102. The insertion column 1104 is cross-shaped, and the insertion column 1104 is inserted and matched with the slot 1105. When the connecting rod 1102, the connecting column 1101 and the screw sleeve 1103 are connected, the cross-shaped insertion column 1104 is first inserted into the slot 1105 for preliminary positioning, and the other end of the screw sleeve 1103 is accurately threadedly connected to the threaded groove on the connecting column 1101.

[0025] By setting the L-shaped connecting section of the blanking plate A800, the inclined groove 601, the connecting column 1101, the connecting rod 1102, the screw sleeve 1103, the insertion column 1104 and the slot 1105, the present invention has the advantages that when too much material adheres to the blanking plate A800 and the blanking plate B900 and needs to be cleaned, the blanking plate A800 and the blanking plate B900 can be detached, which is convenient for removing the adhered material on the blanking plate A800 and the blanking plate B900.

[0026] Please refer to Figures 6 to 12, an embodiment provided by the present invention: a new type of vibrating dehydration screen. The 800L-shaped connecting section of the feeding plate A is positioned and matched with the cross plate A600 through the positioning structure 1200. The positioning structure 1200 includes a fixed strip 1201 and a cam column 1205. The fixed strip 1201 is fixedly arranged on the bottom side of the cross plate A600. An activity plate 1202 is penetrated through the hole on the fixed strip 1201. A positioning plate 1203 is fixedly arranged at the outer end of the activity plate 1202. The positioning plate 1203 is U-shaped. The horizontal section above the positioning plate 1203 is inserted and matched with the positioning groove 801 opened on the longitudinal section of the 800L-shaped connecting section of the feeding plate A. After the horizontal section above the positioning plate 1203 is inserted into the positioning groove 801, the 800L-shaped connecting section of the feeding plate A is fixed to the cross plate A600, and the 800L-shaped connecting section of the feeding plate A and the cross plate A600 are stably connected; a spring 1204 is arranged between the fixed strip 1201 and the positioning plate 1203. The two ends of the spring 1204 are respectively fixedly connected with the fixed strip 1201 and the horizontal section below the positioning plate 1203. The elastic coefficient of the spring 1204 is selected and used by technicians in this field according to the actual situation; the cam column 1205 is rotatably arranged on the bottom side of the cross plate A600. The two ends of the cam column 1205 are respectively rotatably connected with the fixed blocks 1211 fixedly arranged on the bottom side of the cross plate A600 through the rotating shafts 1212. The groove 602 opened on the bottom side of the cross plate A600 is in contact and cooperation with the contour surface of the cam column 1205. The groove 602 does not affect the rotation of the cam column 1205. The contact between the contour surface of the cam column 1205 and the matching groove 602 increases the friction force. Under the action of an external force, the cam column 1205 rotates. In the absence of an external force, the cam column 1205 remains stable; the arc end of the activity plate 1202 is in abutting cooperation with the curved surface of the cam column 1205. A connecting plate A1206 is fixedly arranged on the contour of the cam column 1205. The connecting plate A1206 is connected with a connecting plate B1208 through a telescopic rod 1207. A gap is formed between the connecting plate A1206 and the connecting plate B1208. The fingers of the staff can pass through the gap between the connecting plate A1206 and the connecting plate B1208, which is convenient for the staff to pull the connecting plate A1206, the telescopic rod 1207 and the connecting plate B1208 as a handle, so as to drive the rotation of the contour of the cam column 1205. Two tracks 1210 are symmetrically and fixedly arranged on the bottom side of the cross plate A600. The tracks 1210 are arc-shaped. A guiding column 1209 is fixedly arranged at the end of the connecting plate B1208. The guiding column 1209 slides and cooperates with the tracks 1210 along the sliding grooves of the tracks 1210. The bottom end of the tracks 1210 is provided with an extension section. The sliding groove of the extension section is communicated with the sliding groove of the tracks 1210. The guiding column 1209 slides and cooperates with the sliding groove of the extension section.When the horizontal section above the positioning plate 1203 is in a butting state with the positioning groove 801, the curved surface of the large-head contour of the cam post 1205 contacts the arc end of the movable plate 1202. At this time, the spring 1204 is in a stretched state. The force on the curved surface of the large-head contour of the cam post 1205 and the arc end of the movable plate 1202 is along the normal direction at the tangent point. The normal line does not coincide with the rotation center of the cam post 1205, and there is a torque. At this time, the horizontal section above the positioning plate 1203 is in a butting state with the positioning groove 801, and the cam post 1205 is restricted in this state; when the positioning plate 1203 is in the pushed-out state, the curved surface of the small-head contour of the cam post 1205 contacts the arc end of the movable plate 1202. At this time, the spring 1204 is in a stretched state. The force on the curved surface of the small-head contour of the cam post 1205 and the arc end of the movable plate 1202 is along the normal direction at the tangent point. The normal line does not coincide with the rotation center of the cam post 1205, and there is a torque. The guide post 1209 is limited in the chute of the extension section of the track 1210, and the cam post 1205 is restricted in this state, making the positioning plate 1203 in the pushed-out state; when it is necessary to push the positioning plate 1203 back, the connecting plate B 1208 is moved upward, and the guide post 1209 enters the arc-shaped chute of the track 1210. Under the push of the spring 1204, the guide post 1209 rotates counterclockwise and moves upward along the arc-shaped chute of the track 1210, and the positioning plate 1203 is pushed back.

[0027] By arranging the fixing strip 1201, the movable plate 1202, the positioning plate 1203, the spring 1204, the cam post 1205, the connecting plate A 1206, the telescopic rod 1207, the connecting plate B 1208, the fixing block 1211 and the rotating shaft 1212, the present invention has the advantages of further fixing the L-shaped connecting section of the blanking plate A 800L and the cross plate A 600, and at the same time being convenient to open without affecting the disassembly of the L-shaped connecting section of the blanking plate A 800L and the cross plate A 600.

[0028] Working principle: According to the selection of the actual screening material of the dewatering screen, the oil cylinder 1000 drives the blanking plate B 900 to move relative to the blanking plate A 800, and adjusts the opening degree of the discharge port of the feeding area formed by the blanking plate B 900 and the blanking section of the blanking plate A 800 to adapt to the feeding amount of the corresponding material. The grabbing device grabs the water-containing material and puts it into the feeding area formed by the blanking plate B 900 and the blanking section of the blanking plate A 800. The material enters the screening box 100 along the gap between the blanking plate B 900 and the blanking section of the blanking plate A 800. The material falls on the screening plate 300. The vibrator 200 works to make the screening box 100 vibrate, the screening plate 300 vibrates accordingly, the screening bars 400 vibrate accordingly. The material falling on the screening plate 300 is quickly dispersed under the vibration. The fine particles and water pass through the sieve slots of the screening bars 400 and fall through the holes of the screening plate 300 from the inner cavity of the screening bars 400, while the larger particles remain on the screening plate 300.

[0029] When too much material adheres to the blanking plate A800 and the blanking plate B900 and needs to be cleaned, the oil cylinder 1000 drives the blanking plate B900 away from the blanking plate A800. Rotate the screw sleeve 1103, and the other end of the screw sleeve 1103 is threadedly separated from the thread groove on the connecting column 1101. The connecting column 1101 and the connecting rod 1102 are no longer fixed, and the blanking plate B900 is taken away. The staff rotates downward the handle composed of the connecting plate A1206, the telescopic rod 1207 and the connecting plate B1208. The guide post 1209 slides clockwise along the arc-shaped chute of the track 1210, and the cam post 1205 rotates accordingly. The arc-shaped end of the movable plate 1202 adjusts from the curved surface of the large head contour of the cam post 1205 to the curved surface of the small head contour of the cam post 1205. The movable plate 1202 is pushed out relative to the fixed strip 1201, and the positioning plate 1203 is pushed out. When the guide post 1209 moves to the bottom of the arc-shaped chute of the track 1210, the connecting plate B1208 moves vertically up and down. The guide post 1209 is limited in the chute of the extended section of the track 1210. The horizontal section above the positioning plate 1203 is separated from the positioning groove 801, and the blanking plate A800 is taken away. The materials adhering to the taken-away blanking plate A800 and the blanking plate B900 are removed. After cleaning the blanking plate A800 and the blanking plate B900, dock the L-shaped connecting section of the blanking plate A800 with the cross plate A600, and then move up the connecting plate B1208. The guide post 1209 enters the arc-shaped chute of the track 1210. Under the pushing force of the spring 1204, the guide post 1209 rotates counterclockwise and moves up along the arc-shaped chute of the track 1210. The arc-shaped end of the movable plate 1202 adjusts from the curved surface of the small head contour of the cam post 1205 to the curved surface of the large head contour of the cam post 1205. The movable plate 1202 is pushed back relative to the fixed strip 1201, the positioning plate 1203 is pushed back, and the horizontal section above the positioning plate 1203 is docked with the positioning groove 801 to fix the blanking plate A800 and the cross plate A600. Then install the blanking plate B900, insert the cross-shaped insertion post 1104 into the insertion slot 1105, and rotate the screw sleeve 1103 in the reverse direction. The screw sleeve 1103 moves along the connecting rod 1102 until the other end of the screw sleeve 1103 is threadedly connected to the thread groove on the connecting column 1101 to fix the blanking plate B900 and continue to use.
