Description

Technical Field

[0001] The invention relates to the technical field of carbon slag water treatment, and in particular to a circulating water treatment device and a treatment method for waste incineration fly ash resource water. Background Art

[0002] Filter press is a pressurized filtration device commonly used for solid-liquid separation. When the filter press is working, each filter plate is pressed between the thrust plate and the pressing plate by the pressing oil cylinder, and a filter chamber wrapped by filter cloth is formed between the filter plates. The filter chamber is sealed and maintains a certain pressing force under the thrust of the pressing oil cylinder. During filtration, the feed pump pumps the material into the filter chamber. The solid particles contained in the material during the flow process are intercepted by the filter cloth to form a filter cake. The filtrate passes through the filter cloth and is discharged from the filter chamber to achieve solid-liquid separation.

[0003] Chinese patent application number CN202020036851.2 discloses a box filter press that is easy to unload, including a crossbeam, a filter plate connected between the front and rear crossbeams, a diaphragm plate arranged between the two filter plates, a slide rail arranged at the upper and lower ends of the filter plate, a scraper mounting seat connected to the slide rail, a scraper arranged between the scraper mounting seats, a connecting rod hinged at the top of the upper scraper mounting seat, the other end of the connecting rod is hinged to the top of the diaphragm plate, a collecting bucket is arranged below the filter plate, and a transport pipe and a dragon mechanism are arranged below the collecting bucket. The utility model has a reasonable structural design, scrapers are movably connected on both sides of the filter plate, a connecting rod is hinged between the scraper and the diaphragm plate, the filter plate and the diaphragm plate are automatically unloaded during the retraction of the pressing plate, the scraper moves to the middle of the filter plate, and the filter residue remaining on the surface of the filter plate is removed without manual processing, which can solve the problem that the viscosity of the filtered material is large and the filter cake is difficult to completely peel off from the filter cloth by its own weight.

[0004] Chinese patent application number CN202122637330.X discloses a high-efficiency quick-open filter press, which is used to solve the problem that a lot of silt will be stuck to the filter plate when the existing filter press is frequently used for sewage treatment for a long time, causing the filter plate to be blocked, and long-term cleaning or improper cleaning will greatly reduce the service life of the filter press. The four corners of the lower end of the frame are fixedly installed with a base, the middle of the frame is fixedly installed with a main beam, one side of the main beam is fixedly installed with a hydraulic telescopic device, one end of the hydraulic telescopic device is fixedly installed with a clamping plate, one side of the clamping plate is installed with a plurality of filter plates arranged in sequence, one side of the filter plate is installed with a thrust plate, the other side of the main beam is installed with a feed port, one side of the feed port is installed with a filling pipe, one side of the frame is installed with a water tank, the upper end of the frame is fixedly installed with a fixed frame, and the lower end of the frame is provided with a conveying structure.

[0005] However, the above solution may cause the following problems during use:

[0006] 1. When the prior art is in use, the filter plate needs to be displaced a certain distance relative to the diaphragm plate to drive the scraper to move completely on the filter plate to completely remove the filter residue thereon. The movement of the filter plate takes a certain amount of time, so it will affect the cleaning efficiency to a certain extent. In addition, the adjacent filter plates and diaphragm plates are connected to the scraper through connecting rods to form an integral structure, which makes it inconvenient to disassemble and assemble a single filter plate during subsequent maintenance, making it inconvenient to use.

[0007] 2. When the filter press is used frequently for a long time, a lot of materials will stick to the filter plate and cause blockage. If it is not cleaned for a long time or is not cleaned properly, the service life of the filter press will be greatly reduced. The existing technology achieves the effect of clearing the blockage by flushing the filter plate, but the material is stuck in the mesh of the filter plate. If it is flushed from the outside to the inside, the material will be stuck tighter and tighter in the mesh of the filter plate.

[0008] 3. When filtering materials, the existing filter press equipment can only filter one material at a time, and cannot filter two materials at the same time, thereby increasing the cost investment. Summary of the invention

[0023] S3: The two separated substances enter the filter press assembly, and the high-pressure gas is rushed into the air inlet pipe and enters the air chamber through the ventilation pipe, causing the sealing cloth to expand outward and squeeze the material in the material chamber;

[0024] S4: The squeezed water enters the filter chamber through the filter cloth, flows into the manifold through the three-way water hole, and finally flows into the external circulating water pool, and is depressurized through the air inlet pipe;

[0029] 2. The reciprocating assembly and the knocking assembly are coordinated. The servo motor works and drives the wheel to rotate through the commutator. The connecting rod is eccentrically connected to the wheel, and the connecting rod is hinged to the reciprocating shaft, thereby driving the reciprocating shaft to move back and forth. When the reciprocating shaft moves back and forth, due to the inertia of the knocking hammer, the spring and the knocking hammer swing back and forth, knocking on the force blocks on the extrusion and the filter, causing the extrusion and the filter to vibrate, and knocking off the residual material adhering to the extrusion and the filter.

[0030] 3. Connect the flushing pipe to the water pump in the external circulating water pool, drain part of the water in the circulating water pool into the flushing pipe, and spray it out through the flushing port to impact the filter cloth on the filter element to prevent the material after filtration from clogging the mesh on the filter cloth and affecting the filtration effect. At the same time, the water sprayed out of the flushing port will flow into the confluence pipe through the three-way water hole on the filter chamber and finally flow back to the circulating water pool.

[0045] See also Figure 1 , Figure 2 and Figure 7, considering that after the material is filtered, the material will form a cake shape and fill the material chamber 31 of the cleaning piece 3. At this time, the cake-shaped material needs to be scraped and discharged to prevent the material from sticking to the filter press assembly. The cleaning piece 3 is provided with two material chambers 31 distributed front and back. The material chamber 31 is used to hold the material injected from the feed pipe 112.

A plurality of through holes 34 are opened on the cleaning member 3. The through holes 34 are distributed at the four corners of the material chamber 31. The through holes 34 are used to guide the water filtered out to the conduit 111 for collection, and finally flow into the external circulating water pool.

[0046] See also Figure 1 , Figure 8 and Fig. 9, considering that the material is filtered, after the cake-shaped material is discharged, part of the material will be blocked in the mesh of the filter cloth 42. If it is not cleaned, the filter cloth 42 will be completely blocked after a long time, affecting the discharge of water and further affecting the filter pressing effect of the material.

When the reel 17 rotates, since the reel 17 is fixedly connected to the pull rope 35, one reel 1 7 is used to reel in the pull rope 35, and the other reel 17 is used to stretch the pull rope 35. After rotating for a period of time, the servo motor 15 reverses, and the two reels 17 also reverse, and then the reel 17 controls the scraper block 32 and the scraper rope 33 to move back and forth by reeling in the pull rope 35. The two ends of the pull rope 35 pass through the corresponding guide wheels 36 and are fixedly connected to the two reels 17. The end of the pull rope 35 fixed to the reel 17 is wound around the reel 17. Winding part of the pull rope 35 around the reel 17 can ensure that the other reel 17 is stretched while the reel 17 is reeled, so as to facilitate the reciprocating movement of the scraper block 32 and the scraper rope 33.

[0048] See also Figure 1 , Figure 2 and Figure 3, considering that after the material in the material chamber 31 is cleaned and discharged, there will still be a small amount of material adhering to the sealing cloth 22 and the filter cloth 42, it is necessary to vibrate the extrusion member 2 and the filter member 4 to separate the material adhering to the sealing cloth 22 and the filter cloth 42, the front and rear ends of the extrusion member 2, the cleaning member 3 and the filter member 4 are fixed with a clamping block 5, and the inner side of the frame 1 is fixed with a slide groove 16, and the extrusion member 2, the cleaning member 3 and the filter member 4 are slidably connected with the slide groove 16 through the clamping block 5, and the clamping blocks 5 fixed at the front and rear ends of the extrusion member 2, the cleaning member 3 and the filter member 4 are slidably connected with the slide groove 16 through the clamping block 5, It is convenient to quickly inspect and replace the extrusion member 2, the cleaning member 3 and the filter member 4. The front and rear ends of the extrusion member 2 and the filter member 4 are fixed with force blocks 6. The extrusion member 2 and the filter member 4 are slidably connected to the knocking assembly through the force blocks 6. The knocking assembly includes two front and rear symmetrical reciprocating shafts 18. One end of the reciprocating shaft 18 is slidably connected to the frame 1, and the other end of the reciprocating shaft 18 is slidably connected to the fixed plate 13. A plurality of springs 181 are fixed on the reciprocating shaft 18. The upper ends of the springs 181 are fixed with knocking hammers 182. Springs 181 are provided between the plurality of force blocks 6. The servo motor 15 works and drives the rotating wheel 92 to rotate through the commutator 91, the connecting rod 93 is eccentrically connected to the rotating wheel 92, the connecting rod 93 is hinged to the reciprocating shaft 18, and then drives the reciprocating shaft 18 to reciprocate. When the reciprocating shaft 18 reciprocates, due to the inertia of the knocking hammer 182, the spring 181 and the knocking hammer 182 swing back and forth, knocking the force block 6 on the extrusion member 2 and the filter member 4, so that the extrusion member 2 and the filter member 4 vibrate, and knock off the residual materials adhered to the extrusion member 2 and the filter member 4. The reciprocating assembly includes a bracket 9, and a commutator 91 is fixed on one side of the bracket 9. The output end of the commutator 91 A rotating wheel 92 is fixed, and the input end of the commutator 91 is transmission-connected to the servo motor 15. A connecting rod 93 that is rotatably connected is eccentrically arranged on one side of the rotating wheel 92. The connecting rod 93 is rotationally connected to the reciprocating shaft 18. The servo motor 15 drives the commutator 91 to rotate, and the commutator 91 drives the rotating wheel 92 to rotate. Since the connecting rod 93 is eccentrically arranged with the rotating wheel 92, and the connecting rod 93 is hinged with the rotating wheel 92 and the reciprocating shaft 18, when the rotating wheel 92 rotates, the reciprocating shaft 18 is driven to reciprocate, and then the spring 181 and the knocking hammer 182 on the reciprocating shaft 18 are reciprocated to achieve the knocking effect.

[0049] See also Figure 1 , Figure 2 and Fig.10Considering that two different materials may be mixed together when discharging at the same time, it is necessary to separate the two materials. The discharging assembly includes two rotatably connected discharge plates 8. The lower ends of the two discharge plates 8 are rotatably connected to support rods 81 respectively. The other ends of the support rods 81 are rotatably connected to sliding blocks 83. The sliding blocks 83 are threadedly connected to threaded rods 82. The threaded rods 82 are rotatably connected to the rotational connection of the discharge plates 8. The lower ends of the threaded rods 82 are rotatably connected to lifting plates 84. 84 is fixedly connected to the frame 1, and the lower end of the lifting plate 84 is fixed with a motor 86 that is transmission-connected to the threaded rod 82. The motor 86 is transmitted through the bevel gear and the threaded rod 82. At the same time, since the support rod 81 is hinged with the sliding block 83 and the discharge plate 8, the sliding block 83 is controlled to move up and down through the forward and reverse rotation of the threaded rod 82, and the discharge plate 8 is controlled to rotate and fold to realize the discharge of the pancake-shaped material. At the same time, the telescopic rod 85 is used to fix the discharge plate 8 and the lower end of the filter press assembly to ensure the sealing between the filter press assembly and the discharge plate 8. The lower end of the lifting plate 84 is fixed with two telescopic rods 85 which are symmetrically distributed front and back. The lower end of the telescopic rod 85 is fixed with a fixed beam 87, which is fixed on the frame 1. The rotation connection of the two discharge plates 8 is located in the center of the extrusion part 2, the cleaning part 3 and the filter part 4. The two discharge plates 8 are located above the external conveying equipment. When the discharge plates 8 are opened, the cake-shaped materials will directly fall onto the corresponding conveying equipment, and the two materials will be transported to the corresponding processing stations. The materials are discharged through the discharge assembly, which is conducive to the two different filter presses. The materials after filtering are separated and discharged to prevent two different materials from mixing together. The two reels 17 of the winding assembly rotate, one reel 17 winds up the pull rope 35, and the other reel 17 unwinds the pull rope 35. The reels 17 wind up and unwind one by one, thereby driving the scraper block 32 and the scraper rope 33 to move. The scraper rope 33 fits with the sealing cloth 22 of the extrusion component 2 and the filter cloth 42 of the filter component 4, thereby scraping off the materials adhered to the sealing cloth 22 and the filter cloth 42, preventing the materials filtered into cake-like shapes from adhering to the sealing cloth 22 and the three-way water hole 43, which is convenient for discharging.

[0050] When the present invention is used:

[0051] First, a suitable number of filter press assemblies are placed on the frame 1, and the hydraulic cylinder 14 presses the filter press assemblies against the extrusion block 12, the flushing pipe 113 is connected to the cleaning pipe 44 on the filter press assembly, the air inlet pipe 114 is connected to the ventilation pipe 25, the flushing pipe 113 is connected to the water pump in the external circulating water pool, the feed pipe 112 is connected to the two outlets of the external flotation separation equipment, and the air inlet pipe 114 is connected to the external compressed gas equipment;

[0052] Then, the flotation separation equipment puts the separated two substances into the filter press assembly, and the air inlet pipe 114 rushes high-pressure gas, and enters the air chamber 21 through the ventilation pipe 25, so that the sealing cloth 22 expands outward, and squeezes the material in the material chamber 31. The squeezed water enters the filter chamber 41 through the filter cloth 42, and flows into the manifold 111 through the three-way water hole 43, the through hole 34 and the water channel 23, and finally merges into the external circulating water pool. After completion, the pressure is released through the air inlet pipe 114;

[0053] Next, the winding assembly works to drive the scraper block 32 and the scraper rope 33 to move, and scrape the cake-shaped material to prevent the material after filter pressing from adhering to the filter pressing assembly. At the same time, the reciprocating assembly works to drive the reciprocating shaft 18 to reciprocate, and then the spring 181 and the knocking hammer 182 on the reciprocating shaft 18 move back and forth, knocking the force block 6 on the filter pressing assembly to vibrate the filter pressing assembly, and the material is cleaned off the filter pressing assembly. The discharge assembly works to discharge the material after filter pressing, and the material falls onto the corresponding external conveying equipment through the discharge assembly.

[0054] Finally, water in the circulating water pool is introduced into the flushing pipe 113 and sprayed out through the flushing port 45 to flush the filter cloth 42 from the inside to the outside to prevent the mesh of the filter cloth 42 from being blocked by materials.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
