Description

Technical Field

[0001] This utility model relates to the field of sludge dewatering technology, specifically a sludge dewatering device. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device. It is applied in industries such as chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics, and environmental protection. Currently, plate and frame filter presses are widely used in wastewater treatment for filtering sludge and impurities.

[0003] In existing filter presses, some mud residue remains on the filter plate surface during the automatic discharge of mud blocks after the filter plates are disassembled. If the mud residue is not completely discharged, the mud residue will disperse and adhere to the filter plate surface when the filter plates are washed with water, thus affecting the cleaning of the filter plates. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a sludge dewatering device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sludge filter press includes a filter press body. A support frame is movably mounted on the filter press body via an electric slide rail. A movable frame is mounted on the support frame, and a lifting assembly is provided on the support frame to drive the movable frame to move up and down. A vibration assembly is installed at the bottom of the movable frame. The vibration assembly includes a vibration frame plate fixedly mounted at the bottom of the movable frame, multiple flipping rods rotatably mounted on the vibration frame plate, and a drive unit that drives the multiple flipping rods to reciprocate. The vibration frame plate has side holes for the flipping rods to rotate.

[0007] As a further embodiment of this invention, a vibrating rubber ball is also installed at the end of the flipping rod.

[0008] As a further embodiment of this utility model: the lifting assembly includes a pair of sliding sleeves symmetrically fixedly installed on the support frame, a screw is rotatably installed inside the sliding sleeve, and a nut adapted to the screw is slidably arranged inside the sliding sleeve. The screw is driven by a motor provided on the sliding sleeve, and the movable frame is fixedly installed between the two nuts.

[0009] As a further embodiment of this utility model: the drive unit includes a drive shaft, a fixed shaft, sleeves, a drive gear, a half gear, a fixed disc, a torsion spring, and a power module. The drive shaft is rotatably mounted inside the vibration frame plate and is driven by the power module. The fixed shaft is fixedly mounted inside the vibration frame plate, and multiple sleeves are rotatably mounted on the fixed shaft. Fixed discs are also symmetrically fixedly mounted on both sides of the fixed shaft. A flipping rod is fixedly mounted on the sleeve, and a half gear is also fixedly mounted on the sleeve. A torsion spring is also mounted on the rod between the sleeve and the fixed disc of the fixed shaft. The drive gear meshes with the half gear, and the drive gear is fixedly mounted on the drive shaft.

[0010] As a further embodiment of this utility model: the power module includes a hollow disc, a return spring, a winding wheel, and a pull rope. Hollow discs are symmetrically fixedly installed inside the vibration frame at both ends of the drive shaft. The inner wall of the hollow disc is connected to the drive shaft through the return spring. A winding wheel is also fixedly installed on the drive shaft. One end of the pull rope is wound on the winding wheel, and the other end passes through the vibration frame and is connected to the bottom surface of the support frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model incorporates a support frame, a movable frame, a lifting assembly, and a vibration assembly. When the lifting assembly drives the movable frame to move downwards, the flipping rod in the vibration assembly can reciprocate under the action of the driving unit and impact the surface of the filter plate. This causes the surface of the filter plate to vibrate, which in turn causes the mud adhering to the surface of the filter plate to fall off, thus avoiding the phenomenon of incomplete mud discharge from the filter plate.

Detailed Implementation

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] Example 1

[0020] Please see Figure 1-4 A sludge filter press includes a filter press body 1. A support frame 2 is movably mounted on the filter press body 1 via an electric slide rail. A movable frame 3 is mounted on the support frame 2, and a lifting assembly is provided on the support frame 2 to drive the movable frame 3 to move up and down. A vibration assembly is installed at the bottom of the movable frame 3. The vibration assembly includes a vibration frame plate 4 fixedly mounted at the bottom of the movable frame 3, multiple flipping rods 5 rotatably mounted on the vibration frame plate 4, and a drive unit that drives the multiple flipping rods 5 to reciprocate. The vibration frame plate 4 has side holes 6 for the flipping rods 5 to rotate. By setting up the support frame 2, movable frame 3, lifting assembly, and vibration assembly, when the lifting assembly drives the movable frame 3 to move from top to bottom, the flipping rods 5 in the vibration assembly can reciprocate under the action of the drive unit and impact the filter plate surface. The filter plate surface vibrates accordingly, causing the sludge adhering to the filter plate surface to fall off, thus avoiding the phenomenon of incomplete sludge discharge from the filter plate.

[0021] The end of the flipping rod 5 is also equipped with a vibrating rubber ball 7. The vibrating rubber ball 7 is provided to avoid the phenomenon of the flipping rod 5 rigidly impacting the filter plate and causing the filter plate to deform without affecting the cleaning of mud and sludge on the filter plate.

[0022] Specifically, the lifting assembly includes a pair of sliding sleeves 8 symmetrically fixedly installed on the support frame 2. A screw 9 is rotatably installed inside the sliding sleeve 8, and a nut 11 adapted to the screw 9 is slidably arranged inside the sliding sleeve 8. The screw 9 is driven by a motor 10 provided on the sliding sleeve 8, and the movable frame 3 is fixedly installed between the two nuts 11.

[0023] Specifically, the drive unit includes a drive shaft 12, a fixed shaft 13, sleeves 14, a drive gear 15, a half gear 16, a fixed disc 17, a torsion spring 18, and a power module. The drive shaft 12 is rotatably mounted inside the vibration frame plate 4 and is driven by the power module. The fixed shaft 13 is fixedly mounted inside the vibration frame plate 4, and multiple sleeves 14 are rotatably mounted on the fixed shaft 13. Fixed discs 17 are symmetrically fixed on both sides of the sleeves 14. A flipping rod 5 is fixedly mounted on the sleeves 14, and half gears 16 are also fixedly mounted on the sleeves 14. The fixed shaft 13 is located between the sleeves 14 and the fixed discs 17. A torsion spring 18 is also installed on the rod between 7. The drive gear 15 meshes with the half gear 16, and the drive gear 15 is fixedly installed on the drive shaft 12. Specifically, when the power module drives the drive shaft 12 to rotate, the drive gear 15 on the drive shaft 12 meshes with the half gear 16 on the sleeve 14, which can drive the flipping rod 5 to flip at a certain angle. When the meshing between the drive gear 15 and the half gear 16 disappears, the sleeve 14 can reverse under the action of the torsion spring 18, and drive the vibrating rubber ball 7 at the end of the flipping rod 5 to hit the filter plate surface, so that the filter plate surface vibrates and causes the mud adhering to the filter plate surface to fall off.

[0024] Example 2

[0025] This embodiment is an improvement on embodiment 1, specifically as follows:

[0026] Please see Figure 3 and Figure 4 The power module includes a hollow disc 19, a return spring, a winding wheel 20, and a pull rope 21. The hollow disc 19 is symmetrically fixedly installed inside the vibrating frame plate 4 at both ends of the drive shaft 12. The inner wall of the hollow disc 19 is connected to the drive shaft 12 through the return spring. A winding wheel is also fixedly installed on the drive shaft 12. One end of the pull rope 21 is wound on the winding wheel, and the other end passes through the vibrating frame plate 4 and is connected to the bottom surface of the support frame 2. The setting of this power module eliminates the need for additional drive elements to drive the drive shaft 12 to rotate, reducing production costs and power consumption. Specifically, when the vibrating frame plate 4 is driven to move downward, the pull rope 21 can drive the winding wheel to rotate together with the drive shaft 12, causing the flipping rod 5 to impact the surface of the filter plate. Conversely, when the vibrating frame plate 4 moves upward, the drive shaft 12 can reverse under the action of the return spring and rewind the pull rope 21.
