Abstract
Description
Technical Field
[0001] This application relates to the technical field of sludge separation, and specifically to a spiral press filter and a sludge discharge hopper structure. Background Art
[0002] The spiral press filter, also known as the spiral sludge dewatering machine, is a new type of sludge dewatering equipment. It combines a spiral shaft with moving and static ring plates to form a brand-new pressure filtration method. Compared with common plate and frame filters, belt filter presses, and horizontal scroll centrifuges, the spiral press filter has its uniqueness and superiority, so it has been widely used in many fields.
[0003] During the dewatering process, the sludge is first gravity-concentrated in the concentration section and then transported to the dewatering section. As the sludge advances in the dewatering section, the filter slots and pitch gradually become smaller. At the same time, the blocking effect of the backup plate causes great internal pressure on the sludge, and the volume continuously shrinks to achieve the purpose of sufficient dewatering. The fine moving filter slots formed between the fixed ring and the moving ring are used to filter the filtrate, and the inner cavity formed by the spiral shaft and the ring plates is filled with flocculent particles. These particles are transported, squeezed, and formed into a sludge cake during the rotation towards the end back plate.
[0004] When the sludge cake is discharged, it is discharged from the equipment through the discharge hopper for collection. At this time, when the sludge cake moves through the discharge hopper, if there is still residual moisture inside the sludge cake, it will cause the sludge cake to adhere to the inner bottom of the discharge hopper, and finally the sludge cake will accumulate in the discharge hopper and cannot be effectively discharged. Summary of the Utility Model
[0005] The purpose of this application is to provide a spiral press filter and a sludge discharge hopper structure to solve the problem that the sludge cake adheres to the inner bottom of the discharge hopper, and finally the sludge cake accumulates in the discharge hopper and cannot be effectively discharged as mentioned in the above background art.

The pushing mechanism includes a cylinder bolted to the bottom of the storage and mixing tank, a rectangular plate bolted to the output end of the cylinder, and a sealing ring snap-fitted around the outer wall of the rectangular plate.
[0007] By adopting the above technical solution, it can drive the sludge-water mixture to move vertically, thus avoiding the phenomenon of sedimentation.
[0008] Preferably, the spiral press filter further includes: a connecting pipe, and both ends of the connecting pipe are respectively connected to the feed port of the sludge-water separation device and the circular hole on the outer wall of the storage and mixing tank through flange plates.
[0009] By adopting the above technical solution, the muddy water can be stably transported.
[0010] A sludge discharge hopper structure includes the spiral press filter as described in any one of the above. The discharge hopper structure of this sludge discharge hopper structure includes: a vibrating discharge mechanism. The vibrating discharge mechanism is arranged outside the discharge port of the muddy water separation device. The vibrating discharge mechanism includes a fixed connecting plate bolted to the outer wall of the discharge port of the muddy water separation device, a guiding connecting rod welded to the bottom of the fixed connecting plate, a fixed connecting block slidably connected to the guiding connecting rod, and a discharge hopper welded to one side of the fixed connecting block.

[0017] By adopting the above technical solution, the structure above can be driven to displace during the rotation process.
[0018] In summary, the present application includes at least one of the following beneficial effects;
[0019] (1) By providing a cylinder, a rectangular plate and a sealing ring, when the muddy water is inside the storage and stirring tank, the muddy water at the bottom can be displaced vertically by the rectangular plate and thus move upward, which can effectively prevent the phenomenon of muddy water settling at the bottom.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0027] The following is a further detailed description of the embodiments of the present application in conjunction with the attached Figures 1-4 drawings.
[0028] Embodiment 1
[0029] Please refer to Figures 1-4 , the present utility model provides a technical solution: a spiral dewatering machine, comprising: a sludge separation equipment 1, a storage and stirring tank 2, a connection pipeline 4 and a pushing mechanism 5;
[0030] Sludge separation equipment 1. During the sludge separation process, the sludge first undergoes gravity thickening in the thickening section and then is transported to the dehydration section. As the sludge advances in the dehydration section, the filter slits and pitch gradually become smaller. At the same time, the blocking effect of the backup plate causes the sludge to generate a great internal pressure, and the volume continuously shrinks, achieving the purpose of sufficient dehydration. Round holes are provided at the inner bottom and outer wall of the storage and mixing tank 2. A stirring blade driven by a motor is arranged at the top of the storage and mixing tank 2, which can drive the sludge in the storage and mixing tank 2 to be stirred and mixed. Both ends of the connecting pipe 4 are respectively connected to the feed inlet of the sludge separation equipment 1 and the round hole on the outer wall of the storage and mixing tank 2 through flange plates, and the sludge in the storage and mixing tank 2 can be transported into the interior of the sludge separation equipment 1 through the connecting pipe 4 to achieve sludge separation. The pushing mechanism 5 is arranged at the bottom of the storage and mixing tank 2. Through the pushing mechanism 5, the sludge at the inner bottom of the storage and mixing tank 2 can be vertically displaced, so that all the sludge in the storage and mixing tank 2 can be transported through the connecting pipe 4. The pushing mechanism 5 includes a cylinder 501 bolted to the bottom of the storage and mixing tank 2. The cylinder 501 can drive the structure on the output end to move in the vertical direction. A rectangular plate 502 bolted to the output end of the cylinder 501. When the rectangular plate 502 is driven by the cylinder 501 to displace, it can push the sludge in the storage and mixing tank 2 to move. A sealing ring 503 snap-fitted around the outer wall of the rectangular plate 502. The sealing ring 503 can prevent the sludge from flowing through the gaps around the rectangular plate 502 during the vertical movement of the rectangular plate 502.
[0031] Start the cylinder 501 at the bottom of the storage and mixing tank 2. When the cylinder 501 is working, it can push the rectangular plate 502 connected to the output end. At this time, the rectangular plate 502 will stably displace inside the storage and mixing tank 2 to push the sludge. And through the sealing ring 503 arranged around the rectangular plate 502, it can ensure that the sludge will not enter the gap between the rectangular plate 502 and the storage and mixing tank 2. At this time, the sludge will be transported into the feed inlet of the sludge separation equipment 1 through the connecting pipe 4. After the sludge and water are separated, the mud cake is discharged through the discharge port of the sludge separation equipment 1.
[0032] Embodiment 2
[0033] Please refer to Figures 1-4 , the present utility model provides a technical solution: a sludge discharge hopper structure, including: a vibrating discharge mechanism 3;
[0034] The vibrating discharging mechanism 3 is arranged outside the discharging port of the sludge-water separation equipment 1. When the sludge-water separation equipment 1 discharges the sludge cake, the vibrating discharging mechanism 3 can vibrate and convey the sludge cake. The vibrating discharging mechanism 3 includes a fixed connecting plate 301 bolted to the outer wall of the discharging port of the sludge-water separation equipment 1. The fixed connecting plate 301 can effectively fix the structure on one side. The guiding connecting rod 302 welded to the bottom of the fixed connecting plate 301. The guiding connecting rod 302 can prevent the structure on the rod from deviating when performing vertical displacement. The fixed connecting block 303 slidably connected to the guiding connecting rod 302. While the fixed connecting block 303 slides on the guiding connecting rod 302, it can synchronously drive the structure connected to one side to displace. The discharging hopper 304 welded to one side of the fixed connecting block 303. The discharging hopper 304 can stably move in the vertical direction on the guiding connecting rod 302 through the connection of the fixed connecting block 303. The connecting fixing plate 305 vertically welded below the sludge-water separation equipment 1. The connecting fixing plate 305 can stably connect and fix the structure on one side to prevent shaking during operation. The connecting fixing plate 305 is in the shape of a rectangular plate, which can provide the stability of the structure on one side during connection. The bidirectional driving motor 306 bolted to one side of the connecting fixing plate 305. The bidirectional driving motor 306 can be effectively fixed on the connecting fixing plate 305. Connecting shafts are fixed on both output ends of the bidirectional driving motor 306. The bidirectional driving motor 306 can drive the structures on both output ends to rotate stably. The eccentric blocks 307 snap-fitted on the connecting shafts on both sides of the bidirectional driving motor 306. While the eccentric blocks 307 are rotating, they can drive the discharging hopper 304 above to stably move in the vertical direction. The two ends of the eccentric blocks 307 are arc-shaped, which is smoother when contacting the structure on one side, and the eccentric blocks 307 are arranged below the discharging hopper 304.
[0035] When the sludge cake is discharged through the discharging hopper 304, the bidirectional driving motor 306 is started. The bidirectional driving motor 306 will drive the eccentric blocks 307 on both output ends to rotate. At this time, the eccentric blocks 307 will drive the discharging hopper 304 above to move. Since both ends of the discharging hopper 304 are connected to the fixed connecting block 303, and the fixed connecting block 303 can stably move on the guiding connecting rod 302 below the fixed connecting plate 301, the discharging hopper 304 can stably perform vertical displacement at this time. When the eccentric blocks 307 no longer contact the discharging hopper 304, the discharging hopper 304 will vertically descend to its original position, thereby generating vibration, which can effectively prevent the sludge cake from accumulating on the discharging hopper 304.
[0036] The implementation principle of a screw press and a sludge discharging hopper structure of this application is as follows:
[0037] First, start the cylinder 501 at the bottom of the storage and mixing tank 2. When the cylinder 501 is working, it can push the rectangular plate 502 connected to the output end. At this time, the rectangular plate 502 will stably displace inside the storage and mixing tank 2 to push the sludge. And through the sealing rings 503 arranged around the rectangular plate 502, it can ensure that the sludge will not enter the gap between the rectangular plate 502 and the storage and mixing tank 2.
[0038] Secondly, at this time, the sludge will be transported through the connecting pipe 4 into the feed port of the sludge-water separation device 1. After the sludge and water are separated, the mud cake will be discharged through the discharge port of the sludge-water separation device 1.
[0039] Finally, when the mud cake is discharged through the discharge hopper 304, start the bidirectional drive motor 306. The bidirectional drive motor 306 will drive the eccentric blocks 307 on both output ends to rotate. At this time, the eccentric blocks 307 will drive the upper discharge hopper 304 to move. Since both ends of the discharge hopper 304 are connected to the fixed connection blocks 303, and the fixed connection blocks 303 can stably move on the guiding connecting rods 302 below the fixed connection plate 301, at this time, the discharge hopper 304 can stably displace in the vertical direction. When the eccentric blocks 307 no longer contact the discharge hopper 304, the discharge hopper 304 will vertically descend to its original position, thus generating vibration, which can effectively prevent the mud cake from accumulating on the discharge hopper 304.
