Description

Technical Field

[0001] The invention relates to the technical field of treatment of high-concentration chemical wastewater of explosives and pyrotechnics, in particular to anti-clogging treatment equipment for treatment of high-concentration chemical wastewater of explosives and pyrotechnics. Background Art

[0002] The high-concentration chemical wastewater generated during explosives production is extremely complex. It contains not only nitrobenzene compounds, explosives and their analogs, such as TNT, RDX, and HMX, as well as manufacturing intermediates, but is also often accompanied by high concentrations of acids, bases, and inorganic salts. Furthermore, the large amounts of suspended solids, colloids, organic matter, and scaling ions in the wastewater present significant challenges for treatment. Traditional treatment methods, such as chemical neutralization, filtration, and precipitation, are prone to equipment clogging, severely impacting wastewater treatment effectiveness and the proper and stable operation of the equipment.

[0003] During the filtration and treatment of high-concentration chemical wastewater containing explosives, the mixed impurities in the wastewater are easily intercepted and adhere to the surrounding area of the filter baffle when passing through the filter baffle for a long time, which can easily cause blockage problems, resulting in a decrease in wastewater filtration efficiency and even interruption of the treatment process. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: an anti-clogging treatment device for treating high-concentration chemical wastewater of explosives, comprising:

[0005] A filter tube, one end of which is fixedly connected to a water inlet pipe, the other end of which is fixedly connected to a water outlet pipe, the ends of the water inlet pipe and the water outlet pipe away from the filter tube are fixedly connected to a mesh plate, the side of the mesh plate is rotatably connected to a cleaning component, and both sides of the filter tube are fixedly connected to a recovery component;

[0006] An intercepting component, which is used to perform anti-clogging processing, and the side of the intercepting component is fixedly connected to the inner side of the filter tube;

[0007] The intercepting component includes a baffle, a side surface of the baffle is fixedly connected to the inner side of the filter tube, the side surface of the baffle is slidably connected to a sliding rod, one end of the sliding rod away from the baffle is fixedly connected to a connecting frame, a first spring is sleeved on the sliding rod, one end of the first spring is fixedly connected to the connecting frame, the other end of the first spring is fixedly connected to the baffle, and an ejector rod is evenly arranged on the side of the connecting frame close to the baffle, the ejector rod is concentrically arranged with the baffle mesh, the side surface of the ejector rod is fixedly connected to the inner side of the connecting frame, and the side of the baffle away from the connecting frame is rotatably connected to a rotating mechanism;

[0008] After the wastewater continuously flows into the filter tube through the water inlet pipe, it first impacts the baffle, which intercepts the impurities mixed in the wastewater. Its mesh structure can effectively separate suspended matter and particulate matter, achieve preliminary purification, and reduce the subsequent treatment load. Under the continuous impact of the wastewater, the ejector rod drives the connecting frame to move to the side away from the baffle. At the same time, the baffle pulls the first spring through the sliding rod to stretch, preventing the ejector rod from interfering with the wastewater passing speed in the mesh of the baffle.

[0009] Preferably, the rotating mechanism includes a rotating shaft, the side surface of the rotating shaft is rotatably connected to the inner side of the baffle, rotating plates are fixedly connected to both sides of the rotating shaft, curved plates are evenly provided on the side surfaces of the rotating plate, the side surfaces of the curved plates are fixedly connected to the inner side of the rotating plate, the side of the rotating plate close to the baffle is rotatably connected to the connecting shaft, cleaning blocks are evenly provided on the side surfaces of the connecting shaft, the side surfaces of the cleaning blocks are fixedly connected to the inner side of the connecting shaft, and the side of the cleaning block away from the connecting shaft contacts the side of the baffle away from the connecting frame;

[0010] When wastewater continuously impacts the baffle for filtration, the impact force of the water flow drives the rotating plate to rotate around the rotating axis on the side of the baffle. The rotating plate drives the cleaning block to fit the surface of the baffle through the connecting shaft. The friction of the cleaning block continuously scrapes and cleans the sludge, colloid and other impurities attached to the side of the baffle, preventing the sludge from accumulating on the baffle surface and preventing it from penetrating into the mesh and causing blockage, thereby improving the filtration efficiency and service life of the baffle and reducing the frequency of manual cleaning.

[0011] Preferably, in the process of the rotating plate being driven by the rotating shaft to rotate, the curved plates evenly distributed on the side of the rotating plate push the impurities intercepted by the baffle to move to both sides of the filter tube as the rotating plate rotates, and guide the impurities to the recovery component, thereby realizing the collection and transfer of the intercepted impurities, avoiding the accumulation of impurities in the filter tube to form secondary blockage, and ensuring that the recovery process does not require manual intervention, thereby improving the overall smoothness of the wastewater treatment process;

[0012] Preferably, the recovery component includes two recovery pipes, one end of each recovery pipe is fixedly connected to the inner side of the water inlet pipe, the other end of each recovery pipe is fixedly connected to a collection mechanism, the side of each collection mechanism is fixedly connected to the inner side of the filter pipe, the side of each recovery pipe is fixedly connected to a water pump, and the inner side of each recovery pipe near one end of the water inlet pipe is fixedly connected to a one-way valve;

[0013] Preferably, when the wastewater flows into the filter tube, the baffle intercepts the impurities therein. Under the continuous impact of the wastewater, the impurities intercepted by the baffle enter the collection mechanism together with part of the wastewater. The collection mechanism filters and separates the impurities and intercepts them, while the filtered wastewater is temporarily stored in the mechanism;

[0014] Preferably, at this time, the water pump is started and its suction force is used to transport the wastewater in the collection mechanism to the water inlet pipe through the recovery pipe to achieve secondary treatment of the wastewater. A one-way valve is provided at one end of the recovery pipe close to the water inlet pipe, so that the wastewater in the collection mechanism flows smoothly into the water inlet pipe, while preventing the wastewater in the water inlet pipe from flowing back to the recovery pipe, thereby avoiding the risk of pipe blockage caused by wastewater backflow, and at the same time improving the efficiency of repeated wastewater treatment, reducing water resource waste, and reducing the load of subsequent treatment processes. Through the linkage of the collection mechanism, the water pump and the one-way valve, the equipment realizes the separation, recovery and reuse of impurities and wastewater;

[0015] The cam is connected to the filter screen by the support frame, and the support frame has an inner wall that is provided with a filter, and the filter screen is connected to the filter screen by the support frame.

[0016] Preferably, when wastewater flows into the filter tube, the baffle first intercepts the impurities therein, and a large amount of impurities accumulate on the surface of the baffle. When the wastewater impacts the baffle, it also impacts the block. When the block is impacted by the water flow, the connecting rod drives the movable plate to slide in the collection shell, and the movable plate is pushed toward the filter screen along the sliding rod, and the second spring on the filter screen is compressed.

[0017] Preferably, the cleaning component includes a bracket, the side of the bracket is fixedly connected to the inner side of the water outlet pipe, the bottom of the bracket is rotatably connected to a rotating rod, the side of the rotating rod is fixedly connected to a spiral blade, the bottom of the rotating rod is fixedly connected to a cleaning frame, the bottom of the cleaning frame is fixedly connected to a cleaning brush, and the side of the cleaning brush away from the cleaning frame is rotatably connected to the side of the mesh plate.

[0018] The present invention provides an anti-clogging treatment device for treating high-concentration chemical wastewater of explosives. It has the following beneficial effects:

[0019] 1. The anti-clogging treatment equipment for treating high-concentration chemical wastewater containing explosives is provided with an intercepting component. When the baffle intercepts impurities for a long time and causes the mesh to be clogged, the impact force of the wastewater passing through the baffle is weakened. When it is less than the tensile force of the first spring, the first spring pulls the connecting frame toward the baffle. The connecting frame drives the ejection rod through the sliding rod to penetrate into the baffle mesh, ejecting the impurities blocked therein and restoring the filtering function of the baffle. It can respond quickly at the early stage of clogging, avoiding problems such as reduced treatment efficiency, poor water flow and even equipment failure caused by impurity accumulation, thereby improving the anti-clogging performance of the equipment and ensuring the continuity of the treatment of high-concentration chemical wastewater containing explosives.

[0020] 2. The anti-clogging treatment equipment for high-concentration chemical wastewater from explosives is equipped with a rotating mechanism. The rotating plate drives the cleaning block to fit the baffle surface through the connecting shaft. The friction of the cleaning block is used to continuously scrape and clean the sludge, colloid and other impurities attached to the side of the baffle, avoiding the accumulation of sludge on the baffle surface and preventing it from penetrating into the mesh to cause blockage, thereby improving the filtration efficiency and service life of the baffle and reducing the frequency of manual cleaning.

[0021] 3. The anti-clogging treatment equipment for treating high-concentration chemical wastewater from explosives is equipped with a recovery component, which transports the wastewater in the collection mechanism to the water inlet pipe through the recovery pipe to achieve secondary treatment of the wastewater. A one-way valve is set at one end of the recovery pipe close to the water inlet pipe, allowing the wastewater in the collection mechanism to flow smoothly into the water inlet pipe while preventing the wastewater in the water inlet pipe from flowing back into the recovery pipe, avoiding the risk of pipe blockage caused by wastewater backflow, and at the same time improving the efficiency of repeated wastewater treatment, reducing water resource waste, and reducing the load of subsequent treatment processes. Through the linkage of the collection mechanism, water pump and one-way valve, the equipment realizes the separation, recovery and reuse of impurities and wastewater.

[0022] 4. The anti-clogging treatment equipment for high-concentration chemical wastewater from explosives is equipped with a collection mechanism. The sliding of the movable plate expands the opening of the collection shell. Under the push of the water flow, the impurities intercepted by the baffle enter the collection shell, avoiding the accumulation of impurities around the baffle and reducing the risk of baffle clogging. The filter in the collection shell plays a secondary filtration role, intercepting impurities entering with the water flow, and the filtered wastewater flows back into the water inlet pipe through the recovery pipe, realizing wastewater recycling treatment and improving resource utilization. At the same time, the impurities intercepted by the filter are continuously stored in the collection shell, which is convenient for centralized cleaning. It not only effectively solves the baffle clogging problem and extends the service life of the equipment, but also improves the overall treatment efficiency through wastewater circulation, ensuring the stable operation of the high-concentration chemical wastewater treatment system for explosives.

[0023] 5. The anti-clogging treatment equipment for the treatment of high-concentration chemical wastewater from explosives is equipped with a cleaning component. Through the self-driven cleaning of the water flow, it can remove impurities such as sludge and suspended matter remaining on the surface of the mesh plate in real time, avoid mesh blockage due to impurity accumulation, ensure the passage speed of wastewater, and prevent the decline in treatment efficiency due to slowing water flow. No additional power device is required, which reduces the energy consumption and maintenance costs of the equipment. The self-cleaning function can reduce the frequency of manual cleaning, improve the degree of automation and operational stability of the treatment system, and ensure the operation of the high-concentration chemical wastewater treatment process for explosives.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 3 The present invention provides a technical solution: an anti-clogging treatment device for treating high-concentration chemical wastewater of explosives, comprising:

[0035] A filter tube 1, one end of which is fixedly connected to a water inlet pipe 2, and the other end of which is fixedly connected to a water outlet pipe 3. The ends of the water inlet pipe 2 and the water outlet pipe 3 away from the filter tube 1 are fixedly connected to a mesh plate 4, and a cleaning component 7 is rotatably connected to the side of the mesh plate 4. Both sides of the filter tube 1 are fixedly connected to a recovery component 5;

[0036] An intercepting component 6 is used to perform anti-clogging processing, and the side of the intercepting component 6 is fixedly connected to the inner side of the filter tube 1;

[0037] The intercepting component 6 includes a baffle 61, the side of the baffle 61 is fixedly connected to the inner side of the filter tube 1, the side of the baffle 61 is slidably connected to a slide rod 62, and the end of the slide rod 62 away from the baffle 61 is fixedly connected to a connecting frame 63, and a first spring 64 is sleeved on the slide rod 62, one end of the first spring 64 is fixedly connected to the connecting frame 63, and the other end of the first spring 64 is fixedly connected to the baffle 61. Ejector rods 65 are evenly provided on the side of the connecting frame 63 close to the baffle 61. The ejector rods 65 are concentrically arranged with the mesh of the baffle 61, and the side of the ejector rod 65 is fixedly connected to the inner side of the connecting frame 63. The side of the baffle 61 away from the connecting frame 63 is rotatably connected to a rotating mechanism 66;

[0038] After the wastewater continuously flows into the filter tube 1 through the water inlet pipe 2, it first impacts the baffle 61. The baffle 61 intercepts the impurities mixed in the wastewater. Its mesh structure can effectively separate suspended matter and particulate matter, achieve preliminary purification, and reduce the subsequent treatment load. Under the continuous impact of the wastewater, the ejector rod 65 drives the connecting frame 63 to move to the side away from the baffle 61. At the same time, the baffle 61 pulls the first spring 64 through the slide rod 62 to stretch, preventing the ejector rod 65 from interfering with the wastewater passing speed in the mesh of the baffle 61;

[0039] At the same time, under the impact of the wastewater, the rotating mechanism 66 starts to clean the side of the baffle 61, further removing impurities attached to the baffle 61 to prevent them from accumulating on the side to form lumps and affect the filtering effect;

[0040] When the baffle 61 intercepts impurities for a long time and causes the mesh to become clogged, the impact force of the wastewater passing through the baffle 61 weakens and is less than the tensile force of the first spring 64. The first spring 64 pulls the connecting frame 63 toward the baffle 61. The connecting frame 63 drives the ejection rod 65 through the slide rod 62 to penetrate into the mesh of the baffle 61, ejecting the impurities blocked therein, so that the baffle 61 resumes its filtering function. This can quickly respond to the early stage of clogging, avoiding problems such as reduced treatment efficiency, poor water flow, and even equipment failure caused by impurity accumulation, thereby improving the anti-clogging performance of the equipment and ensuring the continuity of the treatment of high-concentration chemical wastewater from explosives.

[0041] See also Figures 1-4 The rotating mechanism 66 includes a rotating shaft 661, the side of the rotating shaft 661 is rotatably connected to the inner side of the baffle 61, and rotating plates 662 are fixedly connected on both sides of the rotating shaft 661. Bent plates 663 are evenly provided on the sides of the rotating plate 662. The side of the bent plate 663 is fixedly connected to the inner side of the rotating plate 662. The side of the rotating plate 662 close to the baffle 61 is rotatably connected to the connecting shaft 664. Cleaning blocks 665 are evenly provided on the side of the connecting shaft 664. The side of the cleaning block 665 is fixedly connected to the inner side of the connecting shaft 664. The side of the cleaning block 665 away from the connecting shaft 664 contacts the side of the baffle 61 away from the connecting frame 63.

[0042] When wastewater continuously impacts the baffle 61 for filtration, the impact force of the water flow drives the rotating plate 662 to rotate around the rotating shaft 661 on the side of the baffle 61. The rotating plate 662 drives the cleaning block 665 to fit the surface of the baffle 61 through the connecting shaft 664. The friction of the cleaning block 665 continuously scrapes and cleans the sludge, colloid and other impurities attached to the side of the baffle 61, preventing the sludge from accumulating on the surface of the baffle 61 and preventing it from penetrating into the mesh and causing blockage. This improves the filtration efficiency and service life of the baffle 61 and reduces the frequency of manual cleaning.

[0043] As the rotating shaft 661 drives the rotating plate 662 to rotate, the curved plates 663 evenly distributed on the side of the rotating plate 662 push the impurities intercepted by the baffle 61 to move to both sides of the filter tube 1 as the rotating plate 662 rotates, and guide the impurities to the recovery component 5, thereby collecting and transferring the intercepted impurities, avoiding the accumulation of impurities in the filter tube 1 to form secondary blockage, and ensuring that the recovery process does not require manual intervention, thereby improving the overall smoothness of the wastewater treatment process;

[0044] See also Figures 1-6 The present invention provides a technical solution: the recovery component 5 includes two recovery pipes 51, one end of the recovery pipe 51 is fixedly connected to the inner side of the water inlet pipe 2, the other end of the recovery pipe 51 is fixedly connected to a collection mechanism 53, the side of the collection mechanism 53 is fixedly connected to the inner side of the filter pipe 1, the side of the recovery pipe 51 is fixedly connected to a water pump 52, and the inner side of the recovery pipe 51 near the end of the water inlet pipe 2 is fixedly connected to a one-way valve 54;

[0045] When wastewater flows into the filter tube 1, the baffle 61 intercepts the impurities therein. Under the continuous impact of the wastewater, the impurities intercepted by the baffle 61 enter the collection mechanism 53 together with part of the wastewater. The collection mechanism 53 filters and separates the impurities and intercepts them, while the filtered wastewater is temporarily stored in the mechanism.

[0046] At this time, the water pump 52 is started, and its suction force is used to transport the wastewater in the collection mechanism 53 to the water inlet pipe 2 through the recovery pipe 51, thereby realizing secondary treatment of the wastewater. The one-way valve 54 provided at one end of the recovery pipe 51 close to the water inlet pipe 2 allows the wastewater in the collection mechanism 53 to flow smoothly into the water inlet pipe 2, while preventing the wastewater in the water inlet pipe 2 from flowing back to the recovery pipe 51, thereby avoiding the risk of pipe blockage caused by wastewater backflow, and at the same time improving the efficiency of repeated wastewater treatment, reducing water resource waste, and reducing the load of subsequent treatment processes. Through the linkage of the collection mechanism 53, the water pump 52 and the one-way valve 54, the equipment realizes the separation, recovery and reuse of impurities and wastewater.

[0047] See also Figure 1-Figure 7 The collecting mechanism 53 includes a collecting shell 531, the side of the collecting shell 531 is fixedly connected to the inner side of the filter tube 1, the side of the collecting shell 531 away from the filter tube 1 is fixedly connected to a straight plate 532, the inner side of the straight plate 532 is fixedly connected to the end of the recovery pipe 51 away from the water inlet pipe 2, the inner side of the collecting shell 531 is fixedly connected to a filter screen 533, the side of the filter screen 533 away from the straight plate 532 is slidably connected to a sliding rod 534, the other end of the sliding rod 534 is fixedly connected to a movable plate 535, and the movable plate 535 is fixedly connected to the inner side of the collecting shell 531. The side of the movable plate 535 is slidably connected to the inner side of the collecting housing 531. A second spring 536 is sleeved on the sliding rod 534. One end of the second spring 536 is fixedly connected to the side of the filter screen 533. The other end of the second spring 536 is fixedly connected to the side of the movable plate 535 close to the filter screen 533. The side of the movable plate 535 away from the sliding rod 534 is fixedly connected to a connecting rod 537. The other end of the connecting rod 537 is fixedly connected to a stopper 538. The side of the stopper 538 is slidably connected to the inner side of the collecting housing 531.

[0048] When wastewater flows into the filter tube 1, the baffle 61 first intercepts the impurities therein, and a large amount of impurities accumulate on the surface of the baffle 61. When the wastewater impacts the baffle 61, it also impacts the block 538. When the block 538 is impacted by the water flow, the connecting rod 537 drives the movable plate 535 to slide in the collection housing 531. The movable plate 535 is pushed toward the filter screen 533 along the sliding rod 534, and the second spring 536 on the filter screen 533 is compressed.

[0049] The sliding of the movable plate 535 causes the opening of the collection housing 531 to expand. Under the push of the water flow, the impurities intercepted by the baffle 61 flow into the collection housing 531, thereby preventing the impurities from accumulating around the baffle 61 and reducing the risk of clogging of the baffle 61. The filter 533 in the collection housing 531 plays a secondary filtering role, intercepting the impurities entering with the water flow, and the filtered wastewater flows back into the water inlet pipe 2 through the recovery pipe 51, thereby realizing wastewater recycling treatment and improving resource utilization. At the same time, the impurities intercepted by the filter 533 are continuously stored in the collection housing 531, which is convenient for centralized cleaning. This not only effectively solves the problem of baffle 61 clogging and extends the service life of the equipment, but also improves the overall treatment efficiency through wastewater circulation, thereby ensuring the stable operation of the high-concentration chemical wastewater treatment system for explosives.

[0050] See also Figures 1-8 The present invention provides a technical solution: the cleaning component 7 includes a bracket 71, the side of the bracket 71 is fixedly connected to the inner side of the water outlet pipe 3, the bottom of the bracket 71 is rotatably connected to a rotating rod 73, the side of the rotating rod 73 is fixedly connected to a spiral blade 72, the bottom of the rotating rod 73 is fixedly connected to a cleaning frame 74, the bottom of the cleaning frame 74 is fixedly connected to a cleaning brush 75, and the side of the cleaning brush 75 away from the cleaning frame 74 is rotatably connected to the side of the mesh plate 4;

[0051] When wastewater in the filter tube 1 continuously flows into the outlet pipe 3 and passes through the mesh plate 4, the wastewater continuously impacts the spiral blade 72, causing it to rotate on the bracket 71. The spiral blade 72 drives the cleaning frame 74 to rotate synchronously through the rotating rod 73. The cleaning brush 75 under the cleaning frame 74 is in contact with the top of the mesh plate 4. As the cleaning frame 74 rotates, the cleaning brush 75 continuously scrapes the surface of the mesh plate 4, achieving dynamic cleaning;

[0052] Through the self-driven cleaning of water flow, the sludge, suspended matter and other impurities remaining on the surface of the mesh plate 4 can be removed in real time, avoiding the clogging of the mesh due to the accumulation of impurities, ensuring the passage speed of wastewater, and preventing the decline in treatment efficiency due to the slowdown of water flow. No additional power device is required, which reduces the energy consumption and maintenance cost of the equipment. The self-cleaning function can reduce the frequency of manual cleaning, improve the degree of automation and operational stability of the treatment system, and ensure the operation of the high-concentration chemical wastewater treatment process of explosives.

[0053] Specific workflow:

[0054] High-concentration chemical wastewater from explosives is first pre-treated and filtered through the mesh plate 4 to remove larger particles of impurities before flowing into the water inlet pipe 2. The wastewater is continuously transported to the filter pipe 1 through the water inlet pipe 2. When it passes through the interception component 6 in the pipe, the interception component 6 performs a secondary interception and separation on the remaining impurities. The intercepted impurities will enter the recovery component 5 to complete centralized collection and discharge;

[0055] The filtered wastewater continues to flow in the filter tube 1 and is discharged through the outlet pipe 3. During the flow of the wastewater, the water flow drives the cleaning component 7 at the outlet end of the outlet pipe 3 to dynamically clean the mesh plate 4 at that part to prevent impurities from adhering to and clogging it. Finally, the wastewater flowing out of the outlet pipe 3 enters the sedimentation tank for subsequent sedimentation, purification and other treatment processes.

[0056] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
