Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, and more specifically to a filter press for sludge treatment. Background Technology

[0002] Filter presses are widely used for sludge dewatering in existing sludge treatment equipment. However, over long-term operation, filter plates and filter cloths accumulate a large amount of sludge and residue, affecting filtration efficiency and cake quality. Existing cleaning methods mainly rely on manual disassembly of filter plates or brush washing, which is not only labor-intensive and operates in harsh environments, but also incomplete, easily leading to filter cloth clogging or sludge residue on the filter plate surface, increasing equipment failure rate and reducing production efficiency. Some existing automatic cleaning devices typically only use jet washing or simple brush washing, lacking the function of scraping off stubborn sludge from the filter cloth surface, and also unable to self-clean the cleaning brushes and tapping cleaning rollers. This design results in uneven cleaning effects, and long-term operation leads to sludge accumulation, reducing the equipment's cleaning capacity, increasing maintenance frequency, and increasing operating costs.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0004] The purpose of this invention is to provide a filter press for sludge treatment that can effectively solve the above-mentioned technical problems.

[0005] To achieve the objectives of this invention, the following technical solution is adopted: A filter press for sludge treatment includes: a filter pressing mechanism for pressing sludge, and a cleaning mechanism for cleaning filter plates and filter cloth, wherein the cleaning mechanism is slidably mounted on top of the filter pressing mechanism along the length direction of the filter pressing mechanism; The cleaning mechanism includes: a cleaning component for cleaning the filter plate and filter cloth; a gantry bracket for mounting the cleaning component; a lifting component for moving the cleaning component up and down along the gantry bracket; and a moving component for moving the gantry bracket along the length of the filter press mechanism. The cleaning assembly includes: a mounting frame; a mounting housing installed at the bottom of the mounting frame; and a second nozzle assembly, a first cleaning brush, a second cleaning brush, a tapping cleaning roller, and a first nozzle assembly for pre-cleaning the filter plate and filter cloth, which are rotatably mounted from top to bottom inside the mounting housing. The tapping cleaning roller is provided with elastic tapping elements and scraping elements arranged at intervals along its circumference. The elastic tapping elements are a retractable structure used to tap the filter plate and filter cloth. The scraping elements are used to scrape off stubborn stains on the filter plate and filter cloth. The second cleaning brush and the first cleaning brush are used to brush the filter plate and filter cloth. The second nozzle group is used to perform a secondary rinsing of the filter plate and filter cloth.

[0006] Furthermore, a cleaning comb for cleaning the first and second cleaning brushes is slidably mounted on the inner side of the mounting housing; a first rack is fixedly connected to the top of the cleaning comb; the first rack is meshed with a first gear, which is rotatably mounted inside the mounting housing; a pressing rod is meshed with the other side of the first gear; the pressing rod includes: a rack portion meshing with the first gear and a pressing portion fixedly connected to the rack portion, the other end of the pressing portion being located outside the mounting housing, near the other set of mounting housings; the first rack, the first gear, and the pressing rod are symmetrically arranged in two sets along the cleaning comb.

[0007] Furthermore, a cleaning perforated plate for cleaning the cleaning comb is also fixedly installed inside the mounting housing. The cleaning perforated plate has a plurality of holes that match the teeth of the cleaning comb, and the shape and spacing of the holes correspond to the teeth of the cleaning comb.

[0008] Furthermore, a second rack is fixedly connected to the cleaning comb, and a second gear is engaged with the top of the second rack. The second gear is coaxially connected to the first nozzle assembly.

[0009] Furthermore, the top of the second rack is provided with a first connecting tooth and a second connecting tooth from left to right, and a gap is provided between the first connecting tooth and the second connecting tooth.

[0010] Furthermore, a third rack is fixedly connected to the cleaning comb, and a third gear is engaged at the bottom of the third rack. The third gear is coaxially connected to the second nozzle assembly.

[0011] Furthermore, a telescopic block is connected to one side of the cleaning comb, and the other end of the telescopic block is connected to the mounting housing. A return spring is installed inside the telescopic block.

[0012] Furthermore, a mounting box is fixedly installed on one side wall along the length of the mounting housing. Inside the mounting box, from top to bottom, a drive gear, a first driven gear, and a second driven gear are installed in sequence. The drive gear, the first driven gear, and the second driven gear are coaxially connected to the first cleaning brush, the second cleaning brush, and the tapping cleaning roller, respectively. The drive gear is driven to rotate by a drive motor.

[0013] Furthermore, the mounting frame includes two horizontal bars arranged along the front and rear of the filter press mechanism; at least two sets of telescopic bars arranged along the left and right directions of the filter press mechanism and respectively connected to the ends of the two vertical bars; vertical bars arranged along the height direction and connected to the ends of the telescopic bars and the horizontal bars; and connecting bars respectively arranged at the bottom of the vertical bars on both sides. Furthermore, a first connecting block and a second connecting block are respectively fixedly installed at the middle of the top of the two crossbars. A threaded rod is threadedly connected between the first connecting block and the second connecting block. One end of the threaded rod is drivenly connected to the output end of the adjustable pitch motor. The adjustable pitch motor is fixedly installed on a motor mounting base, and the motor mounting base is fixedly installed on one side of one of the crossbars. The threads at both ends of the threaded rod have opposite directions. When the adjustable pitch motor drives the threaded rod to rotate, it causes the first connecting block and the second connecting block to move relative to or towards each other, thereby causing the two sets of mounting housings to move closer to or further away from each other.

[0014] Compared with existing technologies, the present invention has the following advantages: The present invention achieves fully automatic cleaning of filter plates and filter cloths by setting up a multi-stage cleaning mechanism that can move along the length of the filter press and is adjustable in height. The cleaning mechanism sequentially completes pre-rinsing, brushing, tapping cleaning, secondary rinsing, and self-cleaning of the cleaning brushes, thoroughly removing sludge, fiber debris, and stubborn stains adhering to the surface of the filter plates and filter cloths. Simultaneously, it self-cleans the cleaning brushes and tapping cleaning rollers, improving cleaning efficiency and equipment operational stability, reducing manual maintenance and labor intensity, and achieving a highly efficient, continuous, and reliable sludge treatment process.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0020] like Figures 1 to 12 As shown, the present invention relates to a filter press for sludge treatment, comprising: a filter press mechanism for pressing sludge, and a cleaning mechanism for cleaning the filter plates and filter cloth of the filter press mechanism after the pressing is completed, the cleaning mechanism being slidably mounted on the top of the filter press mechanism along the length direction of the filter press mechanism.

[0021] The cleaning mechanism includes: a cleaning component for cleaning the filter plates and filter cloth; a gantry support for mounting the cleaning component; a lifting component for moving the cleaning component up and down along the gantry support to facilitate sequential cleaning of the filter plates and filter cloth; and a moving component for moving the gantry support along the length of the filter press mechanism.

[0022] The moving component includes: a guide rail arranged along the length of the filter press mechanism, with two guide rails symmetrically installed on the front and rear sides of the filter press mechanism; and movable wheels slidably mounted on the guide rails, connected by a motor (not shown, the motor is located at...). Figure 2 The moving wheel (marked on the rear side) drives the moving wheel to rotate, thus allowing the moving wheel to slide along the guide rail.

[0023] The gantry support includes: two uprights mounted on top of the moving assembly, and a crossbeam fixedly mounted on top of the two uprights.

[0024] The lifting assembly includes: a dual-axis motor fixedly installed in the middle of the top of the crossbeam; winches symmetrically installed on both sides of the dual-axis motor and fixedly installed on the top of the crossbeam, with the output end of the dual-axis motor and the output end of the winch being connected in a transmission manner; a pulley mounting base fixedly installed on one side of the crossbeam; and pulleys rotatably installed on the pulley mounting base. The pulleys and pulley mounting bases are matched with the winch to limit the sling of the winch. To further enhance the stability of the lifting, a limit rod can be installed on the opposite side of the winch to reduce the possibility of swaying. Alternatively, the design of the winch and pulleys can be adjusted to use a common telescopic cylinder drive and lifting module, as long as a stable lifting effect can be achieved.

[0025] The cleaning components include: a mounting frame, which is generally cuboid in shape; the mounting frame includes two horizontal bars arranged along the front and rear of the filter press mechanism; at least two sets of telescopic rods arranged along the left and right directions of the filter press mechanism and respectively connected to the ends of the two vertical bars, the horizontal bars and telescopic rods serving a supporting function; vertical rods arranged along the height direction and connected to the ends of the telescopic rods and the horizontal bars; and connecting rods respectively arranged at the bottom of the vertical rods on both sides, the connecting rods on the same side being connected to mounting housings along the front and rear directions of the filter press mechanism, so that the mounting housings are symmetrically arranged in two sets; the distance between the two sets of mounting housings can be adjusted by extending and retracting the telescopic rods.

[0026] A first connecting block and a second connecting block are fixedly installed at the middle of the top of the two crossbars respectively. A threaded rod is threadedly connected between the first connecting block and the second connecting block. One end of the threaded rod is connected to the output end of the adjustable pitch motor. The adjustable pitch motor is fixedly installed on the motor mounting base, which is fixedly installed on one side of one of the crossbars. The threads at both ends of the threaded rod turn in opposite directions. When the adjustable pitch motor drives the threaded rod to rotate, it causes the first connecting block and the second connecting block to move relative to or towards each other, thereby causing the two sets of mounting housings to move closer to or further away from each other.

[0027] The two sets of mounting shells have liquid inlets on opposite sides, which are connected to a water source for receiving water.

[0028] The interior of the mounting housing is hollow, with an opening on one side of the two sets of mounting housings that are close to each other. Both sets of mounting housings contain identical structures. Taking one set as an example: The mounting housing contains, from top to bottom, a second nozzle assembly, a first cleaning brush, a second cleaning brush, a striking cleaning roller, and the first nozzle assembly. The first nozzle assembly is used for pre-cleaning the filter plates and filter cloth. The second nozzle assembly has the same structure as the first nozzle assembly, including a cylinder and high-pressure nozzles mounted on the cylinder. The striking cleaning roller has springs spaced at intervals along its circumference. The system includes a striking and scraping component. The striking component is a retractable structure used to strike the filter plates and filter cloth. The scraping component is used to remove stubborn stains from the filter plates and filter cloth. The second cleaning brush and the first cleaning brush are used to scrub the filter plates and filter cloth. The second nozzle assembly is used for secondary rinsing of the filter plates and filter cloth. Through multi-stage combined cleaning, different types of sludge can be removed in stages: pre-wetting and softening, brushing and peeling, striking and scraping to remove stubborn clumps, and secondary rinsing to thoroughly remove residues, greatly improving cleaning thoroughness and reducing the risk of filter cloth damage.

[0029] A cleaning comb for cleaning the first and second cleaning brushes is slidably mounted on the inner side of the mounting housing; the cleaning comb has comb teeth; a first rack is fixedly connected to the top and bottom of the cleaning comb; the first rack is meshed with a first gear, which is rotatably mounted inside the mounting housing; a pressing rod is meshed with the other side of the first gear; the pressing rod includes: a rack part meshing with the first gear, and a pressing part fixedly connected to the rack part, the other end of the pressing part being located outside the mounting housing, close to the other set of mounting housings, and a flexible rubber strip is installed at the end of the pressing part for initial scraping and cleaning of the filter plate and filter cloth; when the two sets of mounting housings are close to each other... Two sets of extrusion parts abut against each other, causing the first gear to drive the first rack to slide, thereby bringing the cleaning comb closer to the first and second cleaning brushes. A cleaning perforated plate for cleaning the cleaning comb is also fixedly installed inside the housing. The cleaning perforated plate has several holes that match the teeth of the cleaning comb, and the shape and spacing of these holes correspond to the teeth of the cleaning comb. When the cleaning comb moves outward from the housing, the cleaning perforated plate limits the movement of the teeth. When the cleaning comb returns inward, the edges of the holes in the cleaning perforated plate scrape impurities from the surface of the cleaning comb, mechanically removing the impurities and preventing secondary contamination from the teeth.

[0030] A telescopic block is also connected to one side of the cleaning comb, and a return spring is installed inside the telescopic block. The telescopic block is installed inside the mounting housing and is used to drive the cleaning comb to reset when the two sets of mounting housings are far apart. The telescopic block and the return spring realize the reliable reset function of the cleaning comb, ensuring that the comb body automatically returns to the initial position after the housings are separated, avoiding jamming, simplifying the control logic, and improving the recoverability of the equipment.

[0031] Please see Figure 6 and Figure 7 A second rack is fixedly connected to the cleaning comb, and a second gear is meshed with the top of the second rack. The second gear is coaxially connected to the cylinder of the first nozzle assembly. The top of the second rack is provided with a first connecting tooth and a second connecting tooth from left to right, and a gap is provided between the first connecting tooth and the second connecting tooth. The first connecting tooth is used to limit the second gear to prevent the second gear from shaking. The second connecting tooth is used to drive the second gear to rotate, so that the first nozzle assembly rotates upward, thereby rinsing the impact cleaning roller. The size of the gap is adjusted based on the stroke of the extrusion part, so that when the extrusion part is pushed into the mounting housing, the first nozzle assembly rotates towards the impact cleaning roller.

[0032] A third rack is also fixedly connected to the cleaning comb. A third gear is meshed at the bottom of the third rack. The third gear is coaxially connected to the cylinder of the second nozzle assembly. The third gear is rotatably installed inside the mounting housing. The third rack is the same as the extrusion rod, and the third gear is the same as the second gear.

[0033] A mounting box is fixedly installed on one side wall along the length of the housing. Inside the mounting box, from top to bottom, are a drive gear, a first driven gear, and a second driven gear. The drive gear, the first driven gear, and the second driven gear are coaxially connected to the first cleaning brush, the second cleaning brush, and the tapping cleaning roller, respectively. The drive gear is driven by a drive motor, and the first and second driven gears are driven by the drive gear. The drive gear, the first driven gear, and the second driven gear are common gears. As an option, the drive gear is a double gear, and the two gears of the double gear are respectively connected to the first and second driven gears via chains. As another option, the drive gear, the first driven gear, and the second driven gear are all conventional gears and are directly meshed.

[0034] During installation, the filter press mechanism and cleaning mechanism are first fixed to the equipment frame, and the cleaning mechanism is then mounted on the guide rail at the top of the filter press mechanism via a movable component. The mounting frame, formed by the telescopic rod, vertical rod, and connecting rod, defines the installation position of the mounting housing. The distance between the two sets of mounting housings is adjusted by a pitch-adjustable motor driving a threaded rod to adapt to the thickness of the filter plates and filter cloth. The winch and pulleys of the lifting component, driven by a dual-axis motor, enable the lifting of the cleaning component, allowing it to enter the cleaning position between the filter plates and filter cloth.

[0035] During use, the moving component moves along the length of the filter press mechanism under the drive of the motor, allowing the cleaning mechanism to position each filter plate and filter cloth one by one. After positioning, the dual-axis motor drives the winch to descend, causing the two sets of mounting housings to simultaneously enter both sides of the filter plate and filter cloth, thereby bringing the nozzle assembly, cleaning brush, and tapping cleaning roller inside the mounting housing close to the surface of the filter plate and filter cloth.

[0036] During the cleaning process, the first spray nozzle group first sprays high-pressure water to pre-rinse the filter plates and filter cloth surfaces, softening and removing large particles of sludge. Subsequently, the first and second cleaning brushes rotate under the drive of a motor and a double gear set, performing a two-stage brushing of the filter plates and filter cloth surfaces. Further, the striking cleaning roller rotates under the drive of the second driven gear; its circumferentially arranged elastic striking and scraping components sequentially strike and scrape the filter plates and filter cloth, thereby removing stubborn stains. After the brushing and striking actions are completed, the first spray nozzle group sprays high-pressure water to perform a second rinse of the filter plates and filter cloth, further enhancing the cleaning effect.

[0037] During the continuous cleaning of multiple filter plates and filter cloths, sludge and fine fibers adhere to the surface of the cleaning brushes. After all filter plates are cleaned, the lifting assembly is driven upwards, causing the cleaning mechanism to detach from the filter plates and filter cloths. Subsequently, the pitch motor drives the threaded rod again, bringing the two sets of mounting housings closer together until the two sides of the squeezing parts abut against each other. When the squeezing parts come into contact, they drive the meshing rack and gear to rotate, thereby driving the cleaning comb to move inwards, so that the comb teeth of the cleaning comb insert between the first and second cleaning brushes, achieving comb-like stripping cleaning. At the same time, the second rack on the cleaning comb drives the second gear to rotate, causing the second nozzle group to rotate upwards to the corresponding position of the striking cleaning roller. At this time, the drive motor is turned on and the first and second nozzle groups are opened simultaneously, realizing synchronous water washing of the cleaning brushes and the striking cleaning roller, thus completing the self-cleaning of the cleaning mechanism.

[0038] When the two sets of mounting housings separate again, the return spring in the telescopic block is released, causing the cleaning comb to automatically return to its initial position; at the same time, the cleaning plate cleans the cleaning comb.

[0039] As can be seen, the present invention achieves pre-rinsing, brushing, tapping cleaning and secondary rinsing of filter plates and filter cloth by combining moving components, lifting components, adjusting mechanism and multi-stage cleaning components, and realizes automatic cleaning of cleaning brush and tapping roller, so as to make the cleaning effect more thorough, the operation more stable and the maintenance more convenient.
