Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to an air-source high-pressure filter press. 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 that was applied to chemical production in the early 18th century and is still widely used in industries such as chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics and environmental protection.

[0003] The filter cloth mounted on the outside of the filter plates in a filter press needs to be disassembled and cleaned once every certain period. However, due to the large number of filter plates on each filter press, the process is cumbersome. Therefore, a cleaning mechanism is installed on the filter press to automatically clean the filter cloth on the filter plates. The existing cleaning mechanism uses a brush and water to clean the filter cloth and the impurities accumulated on one side of the filter cloth. However, this cleaning method easily causes the filter residue to be discharged with the water flow, which is inconvenient to collect and results in a waste of resources. Therefore, an air-source high-pressure filter press is proposed to solve the above problems. Utility Model Content

[0019] like Figure 1-5 As shown, the present invention proposes an air-source high-pressure filter press, which includes a frame 1, with crossbeams 2 fixedly connected to both the front and rear sides of the frame 1, a hydraulic cylinder 4 installed at one end of the frame 1, and a pressure plate 5 located inside the frame 1 fixedly connected to the output end of the hydraulic cylinder 4, and several filter plates 8 slidably placed inside the frame 1. A push plate 3 for driving the filter plate 8 is provided on the crossbeam 2, and a cleaning part 7 for cleaning the filter plate 8 is provided on the push plate 3.

[0020] In this invention, by combining the cleaning component 7 with air energy, the filter cloth on the filter plate 8 can be brushed and washed at the same time, and the attached filter residue can also be blown off by air energy.

[0021] In an optional embodiment, the cleaning component 7 includes two support rods 71 ​​that are symmetrically fixedly connected to the push plate component 3. A mounting plate 72 is fixedly connected between the upper ends of the two support rods 71. A cylinder 74 is fixedly connected to the mounting plate 72, and the output end of the cylinder 74 passes through the mounting plate 72. A mounting bracket 73 is fixedly connected to one end of the cylinder 74 that passes through the mounting plate 72. A servo motor 76 is fixedly mounted to one end of the mounting bracket 73. A rotating screw 77 is rotatably connected to the inner side of the mounting bracket 73, and a slider 75 is threadedly connected to the outer side of the rotating screw 77. The end of the rotating screw 77 near the servo motor 76 is fixedly connected to the output shaft of the servo motor 76. A hollow block 78 is fixedly connected to the lower end of the slider 75. Cleaning brackets 710 are slidably connected to both the left and right sides of the mounting bracket 73. The lower end of the cleaning frame 710 is concave, and several bristles 713 and air outlets 714 are respectively provided in the concave part. The hollow block 78 is connected to a connecting pipe 79 that passes through the mounting frame 73 and is fixed to the cleaning frame 710 on the side near the cleaning frame 710. The hollow frame of the cleaning frame 710 is connected to the air outlets 714 and the connecting pipe 79 respectively. The air outlets 714 are inclined downwards at the air outlet end.

[0022] In this embodiment, the cleaning frame 710, which is lowered and moves back and forth, can repeatedly brush the filter cloth on the filter plate 8 with the bristles 713 in its concave part and the air outlet 714. At the same time, the compressed air discharged can clean the attached filter residue with the bristles 713. Meanwhile, the compressed air blown out can also blow off the filter residue attached to the bristles 713, so that the fallen filter residue can be collected together with the filter cake during the filter cake discharge and collection process. This improves the cleaning effect and makes it easier to collect the filter residue.

[0023] It should be noted that an air tank 6 is installed on the back of the frame 1. The lower surface of the hollow block 78 is connected to an air supply pipe 711, one end of which is connected to the air tank 6. The air supply pipe 711 is a flexible hose. A valve is installed at the connection between the air supply pipe 711 and the air tank 6. The valve controls the discharge of compressed gas. At the same time, an air compressor is connected to the air inlet of the air tank 6 to compress and process air into the air tank 6 for storage. The upper part of the cleaning frame 710 is L-shaped, and its L end fits against the left and right sides of the mounting frame 73, while the lower ends of the left and right sides of the mounting frame 73 block the upper part of the recessed area of ​​the cleaning frame 710. Each crossbeam 2 has a U-shaped support frame 9 fixedly connected to its upper surface, while the mounting plate 72 has a guide block 712 fixedly connected to the support frame 9 on its lower surface, which is used to improve the stability of the mounting plate 72 when it slides laterally.

[0024] The slider 75 has a convex shape on both the left and right sides, and the inner walls of the mounting bracket 73 are provided with sliding grooves for the convex end of the slider 75 to slide. The sliding grooves on the inner wall of the mounting bracket 73 provide sliding support for the convex end of the slider 75, allowing the slider 75 to slide back and forth stably.

[0025] In addition, a threaded hole is provided in the middle of the slider 75, and the threaded hole is adapted to the thread on the outside of the rotating screw 77, so that the reciprocating rotating screw 77 can drive the slider 75 to slide back and forth. Rectangular holes are provided on the left and right side walls of the inner cavity of the mounting bracket 73 for the connecting pipe 79 to move, so that the connecting pipe 79 passing through the mounting bracket 73 has space to move back and forth.

[0026] Secondly, several bristles 713 and air outlets 714 are equidistantly distributed from top to bottom, and the bristles 713 and air outlets 714 are staggered in front and behind. The bristles 713 are fixedly installed on the cleaning frame 710. Through the symmetrically distributed bristles 713 and air outlets 714, the filter cloth on the filter plate 8 can be brushed and washed, and compressed air can be used to clean the filter cloth together with the bristles 713 and blow off the filter residue.

[0027] In an optional embodiment, the push plate component 3 includes two slides 33 symmetrically slidably connected to two crossbeams 2, and two support rods 71 ​​are symmetrically fixedly connected to the two slides 33. The upper end of the slide 33 is U-shaped and the lower end is T-shaped. The end of the frame 1 near the hydraulic cylinder 4 is fixedly connected to a drive motor 31 located below the crossbeam 2. The drive motor is also a servo motor. The output shaft of the drive motor 31 is fixedly connected to a drive screw 32 that passes through the T-shaped end of the slide 33. The inner side of the U-shaped end of each slide 33 is rotatably connected to two rotating shafts 35 that pass through the U-shaped end of the slide 33, and each rotating shaft 35 is fixedly connected to a stop block 34.

[0028] It should be noted that each abutment block 34 is rotatably connected to the U-shaped end of the slide 33 via a pivot 35, and a torsion spring sleeved on the pivot 35 is installed between the lower end of each abutment block 34 and the inner side of the U-shaped end of the slide 33. A protrusion 36 is fixedly connected to one end of each pivot 35 that passes through the U-shaped end of the slide 33, and a rod 37 that passes through the protrusion 36 is inserted into the end of each protrusion 36 that is away from the pivot 35.

[0029] In this embodiment, since the two abutments 34 at the U-shaped end of each slide 33 are supported by the rotating shaft 35 and the torsion spring, during the sliding process of the slide 33, the abutments 34 that are supported and limited by the insert rod 37 push and pull the ears of the filter plate 8 to achieve the sequential separation of several filter plates 8 and their gradual fitting and closing.

[0030] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Since this utility model is mainly used to protect mechanical structures, the control method and circuit connection and other technical means will not be described in detail here.

[0031] The working principle in the above embodiments is as follows: Since the two abutments 34 at the U-shaped end of each slide 33 are supported by the rotating shaft 35 and the torsion spring, and the slide 33 is driven by the drive screw 32 on the drive motor 31, when the slide 33 slides towards the side closer to the filter plate 8, the insert rod 37 inserted into the corresponding protrusion 36 of the left abutment 34 can restrict the left abutment 34 from rotating counterclockwise, so that after the two abutments 34 move to the ear of a single filter plate 8, the reset slide 33 can pull several filter plates 8 to separate in sequence through the left abutment 34; After each filter plate 8 is separated, the mounting bracket 73 can be lowered by the cylinder 74 to drive the bristles 713 on the two cleaning brackets 710 to adhere to the filter cloth on the left and right sides of each filter plate 8. At the same time, the two cleaning brackets 710 can adhere to the plate frame of the filter plate 8. The servo motor 76, after rotating the screw 77 to drive the slider 75 to slide back and forth, can drive the cleaning brackets 710 to move back and forth, so that the bristles 713 in their concave parts can brush the filter cloth on the filter plate 8, and air can be supplied into the hollow frame 78 through the air tank 6 and the air supply pipe 711. Compressed air is supplied and then conveyed into the hollow part of the cleaning frame 710 through the connecting pipe 79. After being discharged through several air outlets 714, it can be used with the bristles 713 to repeatedly brush the filter cloth on the filter plate 8. At the same time, the discharged compressed air can also clean the attached filter residue with the bristles 713. Meanwhile, the compressed air can also blow off the filter residue attached to the bristles 713. The blown-off filter residue falls along the lower end of the cleaning frame 710, so that the fallen filter residue can be collected along with the filter cake during the filter cake discharge and collection process. After the filter plate 8 is cleaned, insert the rod 37 on the corresponding protrusion 36 of the right abutment 34 to restrict the clockwise rotation of the right abutment 34. At the same time, pull out the rod 37 on the corresponding protrusion 36 of the left abutment 34. The right abutment 34, which cannot rotate clockwise, can push the frontmost filter plate 8 to slide through the ear on the frontmost filter plate 8, so as to drive several filter plates 8 to close in sequence.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
