Description

Technical Field

[0001] This utility model relates to the field of solid waste treatment technology, specifically a filtration device for treating heavy metal solids in barium slag. Background Technology

[0002] The leaching concentration of soluble barium compounds (such as BaCO3 and BaS) in barium slag far exceeds the limits for hazardous waste, classifying it as HW47 hazardous waste. If improperly dumped or handled, it may seep into the soil and groundwater, causing pollution. To reduce the hazards of barium slag, harmless treatment methods can be adopted, such as converting it into water-insoluble barium sulfate (BaSO4) through a chemical reaction and separating it from the waste liquid through filtration. This method can effectively reduce the potential harm of barium slag to the environment and human health.

[0003] Existing heavy metal solid treatment equipment for barium slag can effectively extract harmful substances from barium slag by pouring barium slag and chemical reagents into the equipment. However, because both the barium slag and chemical reagents are in a static state, there are parts on the surface of the barium slag that do not fully come into contact with the chemical reagents, resulting in a small amount of heavy metal barium still remaining in the treated waste residue. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for treating heavy metal solids in barium slag, comprising a reaction chamber, a connecting bracket fixedly connected to the outer surface of the reaction chamber, a cylinder fixedly connected to the end of the connecting bracket away from the reaction chamber, a fixed plate fixedly connected to the telescopic end of the cylinder, a circular cover plate detachably installed at the top of the reaction chamber, a circular connecting rod fixedly connected to the upper surface of the circular cover plate, the top end of the circular connecting rod fixedly connected to the lower surface of the fixed plate, a first motor fixedly connected to the middle of the upper surface of the circular cover plate via a bracket, the output end of the first motor penetrating the circular cover plate and extending into the inner cavity of the reaction chamber, a stirring device fixedly connected to the output end of the first motor, and a stirring device at the top side of the reaction chamber. A first feed inlet and a second feed inlet are fixedly installed, opposite each other at the top of the reaction chamber. A sealing ring is fixedly connected to the inner wall of the reaction chamber. A sieve plate device is fixedly installed at the bottom of the reaction chamber, with the sealing ring positioned above the sieve plate device. A waste liquid tank is fixedly connected to the bottom of the sieve plate device, and the waste liquid tank is positioned directly below the reaction chamber. Support feet are fixedly installed at the bottom of the sieve plate device and the waste liquid tank. A discharge port is fixedly installed at the center of the bottom of the waste liquid tank. The sieve plate device includes a leak switch and a replaceable sieve plate. The leak switch has a pull-out groove inside, and strip-shaped grooves are formed on the inner walls of both sides of the pull-out groove. The replaceable sieve plate is slidably installed inside the strip-shaped grooves and is positioned directly above the waste liquid tank. After cleaning, the agitator is lifted by an air pump, and the replaceable sieve plate can be disassembled for replacement and cleaning, thus achieving solid-liquid separation.

[0005] Preferably, the stirring device includes a transmission rod, the top end of which is fixedly connected to the output end of a first motor. A first rotating shaft is fixedly connected to the outer surface of the transmission rod, and a stirring blade is fixedly connected to the outer surface of the first rotating shaft. A brush is fixedly installed at the bottom outer edge of the stirring blade. A connector is fixedly connected to the bottom end of the transmission rod, and a second rotating shaft is fixedly connected to the bottom of the connector. When the first motor operates, the output end rotates the rotating shaft via the transmission rod, causing the brush at the bottom outer edge of the stirring blade to rotate with the rotating shaft. When the brush contacts the surface of the barium slag heavy metal, it causes the barium slag heavy metal to move, thus allowing the barium slag heavy metal to fully contact and react with the reaction liquid.

[0006] Preferably, the replaceable sieve plate includes a handle and a first sieve plate. The outer surface of the first sieve plate is fixedly connected to the end of the handle. Strip-shaped sliders are fixedly connected to both sides of the handle. The handle is slidably connected to the inside of a strip-shaped groove via the strip-shaped sliders on both sides. After the stirring device is lifted by the cylinder, the replaceable sieve plate can be pulled out through the handle via the strip-shaped sliders, and the filter residue deposited on the inner surface of the sieve plate can be poured out. The cleaned replaceable sieve plate can then be replaced, making the sieve plate that was originally irreplaceable inside the instrument replaceable as needed. This also prevents the filter residue deposited inside the instrument from becoming impossible to clean due to repeated use.

[0007] Preferably, the inner wall of the first sieve plate has an annular groove, and a snap-fit ​​plate is slidably connected inside the annular groove. A second sieve plate is fixedly connected to the bottom of the snap-fit ​​plate. The surface of the second sieve plate has Z-shaped perforations, and a rotating shaft groove is formed at the center of the surface of the second sieve plate. The rotating shaft groove is fitted onto the outer surface of a second rotating shaft, and a circular through hole is formed at the bottom of the first sieve plate. The Z-shaped perforations on the upper surface of the second sieve plate prevent heavy metals from barium slag from clogging the perforations and preventing the liquid from flowing downwards. This solves the problem of clogging of the perforations after repeated use, which affects the filtration speed, thus extending the service life of the filter assembly.

[0008] Preferably, the leakage switch includes a housing and a liquid-separating plate. A switch slot is formed inside the housing, extending through the waste liquid tank. A second motor is fixedly mounted on the outer surface of the housing via a bracket. The output end of the second motor extends through the housing and into the switch slot. A lead screw is fixedly connected to the output end of the second motor. The liquid-separating plate is internally connected to the surface of the lead screw. The liquid-separating plate is slidably disposed inside the switch slot and is sealed and adapted to the waste liquid tank. The liquid-separating plate is retracted by the lead screw fixedly connected to the output end of the second motor, allowing the waste liquid after the chemical reaction is completed to flow into the waste liquid tank and then be discharged through the outlet at the bottom of the waste liquid tank. This effectively prevents liquid from directly flowing into the waste liquid tank while the chemical reaction is in progress.

[0009] This utility model provides a filtration device for treating heavy metal solids in barium slag. It has the following beneficial effects: This filtration device for treating heavy metal solids in barium slag operates via a first motor. The output end of the motor rotates the shaft through a transmission rod, causing the brushes at the bottom outer edge of the stirring blades to rotate along with the shaft. When the brushes come into contact with the surface of the heavy metals in the barium slag, they cause the heavy metals to move, thus allowing the heavy metals in the barium slag to fully contact and react with the reaction liquid.

[0010] After the stirring device is lifted by the cylinder, the replaceable sieve plate can be pulled out by the handle through the strip slider, and the filter residue settled on the inner surface of the sieve plate can be poured out and replaced with the cleaned replaceable sieve plate. This makes the sieve plate that was originally irreplaceable inside the instrument replaceable as needed, and also prevents the filter residue settled inside the instrument from becoming impossible to clean due to repeated use.

[0011] The Z-shaped perforations on the upper surface of the second sieve plate prevent heavy metals from barium slag from clogging the perforations and preventing the liquid from flowing downwards. This solves the problem of clogging of the perforations after repeated use, which affects the filtration speed and extends the service life of the filter components.

[0012] The liquid separator is retracted by the lead screw fixedly connected to the output end of the second motor, so that the waste liquid after the chemical reaction is completed flows into the waste liquid tank and is discharged through the outlet in the middle of the bottom of the waste liquid tank. This can effectively prevent the liquid from flowing directly into the waste liquid tank while the chemical reaction is in progress. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4This utility model provides a technical solution: a filtration device for heavy metal solid treatment of barium slag, comprising a reaction chamber 1; a connecting bracket 6 is fixedly connected to the outer surface of the reaction chamber 1; a cylinder 5 is fixedly connected to one end of the connecting bracket 6 away from the reaction chamber 1; a fixing plate 4 is fixedly connected to the telescopic end of the cylinder 5; a circular cover plate 12 is detachably installed at the top of the reaction chamber 1; a circular connecting rod 11 is fixedly connected to the upper surface of the circular cover plate 12; the top end of the circular connecting rod 11 is fixedly connected to the lower surface of the fixing plate 4; a first motor 3 is fixedly connected to the middle of the upper surface of the circular cover plate 12 via a bracket; the output end of the first motor 3 passes through the circular cover plate 12 and extends into the interior of the reaction chamber 1. At the cavity, a stirring device 14 is fixedly connected to the output end of the first motor 3. A first feed inlet 2 and a second feed inlet 7 are fixedly installed on the top side of the reaction chamber 1, and the first feed inlet 2 and the second feed inlet 7 are arranged opposite to each other at the top of the reaction chamber 1. A sealing ring 15 is fixedly connected to the inner wall of the reaction chamber 1. A sieve plate device 8 is fixedly installed at the bottom of the reaction chamber 1. The sealing ring 15 is located above the sieve plate device 8. A waste liquid tank 13 is fixedly connected to the bottom of the sieve plate device 8, and the waste liquid tank 13 is located directly below the reaction chamber 1. Support feet 9 are fixedly installed at the bottom of the sieve plate device 8 and the waste liquid tank 13. A discharge port 10 is fixedly installed at the middle position of the bottom of the waste liquid tank 13.

[0017] The stirring device 14 includes a transmission rod 141, the top end of which is fixedly connected to the output end of the first motor 3. A first rotating shaft 145 is fixedly connected to the outer surface of the transmission rod 141, and a stirring blade 142 is fixedly connected to the outer surface of the first rotating shaft 145. A brush 144 is fixedly installed at the bottom outer edge of the stirring blade 142. A connector 143 is fixedly connected to the bottom end of the transmission rod 141, and a second rotating shaft 146 is fixedly connected to the bottom of the connector 143. The second rotating shaft 146 is rotatably installed in the 829 rotating shaft groove, which can stabilize the stirring device 14 and prevent the stirring device 14 from colliding with the sieve plate device due to centrifugal force during rotation. The first motor 3 operates, and the output end rotates the first shaft 145 through the transmission rod 141. This causes the brush 144 at the bottom outer edge of the stirring blade 142 to rotate along with the first shaft 145. When the brush 144 contacts the surface of the barium slag heavy metal, it will drive the barium slag heavy metal to move, so that the barium slag heavy metal can fully contact and react with the reaction liquid.

[0018] Please see Figure 5-8This utility model provides a technical solution: a filtration device for heavy metal solid treatment of barium slag. The sieve plate device 8 includes a leakage switch 81 and a replaceable sieve plate 82. The leakage switch 81 has a pull-out groove 83 inside, and strip-shaped grooves 84 are formed on the inner walls on both sides of the pull-out groove 83. The replaceable sieve plate 82 is slidably installed inside the strip-shaped grooves 84. The replaceable sieve plate 82 is located directly above the waste liquid tank 13. After the stirring device 14 is lifted by the cylinder 5, the replaceable sieve plate 82 can be pulled out by the handle 821 through the strip-shaped slider 825, and the filter residue deposited on the inner surface of the sieve plate can be poured out and replaced with the cleaned replaceable sieve plate 82. This makes the sieve plate that was originally irreplaceable inside the instrument replaceable as needed, and also prevents the filter residue deposited inside the instrument from becoming impossible to clean due to repeated use.

[0019] The inner wall of the first sieve plate 822 is provided with an annular groove 828, and a snap-fit ​​plate 826 is slidably connected inside the annular groove 828. The bottom of the snap-fit ​​plate 826 is fixedly connected to a second sieve plate 823. The surface of the second sieve plate 823 is provided with Z-shaped leakage holes 824, and a rotating shaft groove 829 is provided at the center of the surface of the second sieve plate 823. The rotating shaft groove 829 is fitted onto the outer surface of the second rotating shaft 146. The bottom of the first sieve plate 822 is provided with a circular through hole 827. The Z-shaped leakage holes 824 on the upper surface of the second sieve plate 823 can prevent barium slag heavy metals from clogging the leakage holes and preventing the liquid from flowing downward. This solves the problem of leakage hole clogging affecting the filtration speed after repeated use, thus extending the service life of the filter assembly.

[0020] Please see Figure 9 This utility model provides a technical solution: a filtration device for heavy metal solid treatment of barium slag, wherein the leakage switch 81 includes a housing 813 and a liquid separator 815. A switch groove 814 is provided inside the housing 813, penetrating the waste liquid tank 13. A second motor 811 is fixedly mounted on the outer surface of the housing 813 via a bracket. The output end of the second motor 811 penetrates the housing 813 and extends to the switch groove 814. A lead screw 812 is fixedly connected to the output end of the second motor 811. The liquid separator 815 is internally connected to the surface of the lead screw 812. The liquid separator 815 is slidably disposed inside the switch slot 814 and is sealed and adapted to the waste liquid tank 13. The liquid separator 815 is retracted by the lead screw 812 fixedly connected to the output end of the second motor 811, so that the waste liquid after the chemical reaction is completed flows into the waste liquid tank 13 and is discharged through the discharge port 10 at the middle position of the bottom of the waste liquid tank 13. This can effectively prevent the liquid from flowing directly into the waste liquid tank 13 while the chemical reaction is in progress.

[0021] During operation, barium slag and chemical reagents are fed into the reaction chamber 1 through the first inlet 2 and the second inlet 7, respectively. While the reaction is in progress, the liquid-separating plate 815 is closed, and the barium slag and chemical reagents undergo a chemical reaction in the cavity above the sieve plate device 8. At this time, the first motor 3 operates, and its output end rotates the first rotating shaft 145 via the transmission rod 141. This causes the brush 144 at the bottom outer edge of the stirring blade 142 to rotate along with the first rotating shaft 145. When the brush 144 contacts the heavy metal surface of the barium slag, it drives the heavy metal to move, ensuring sufficient contact and reaction between the barium slag and the reaction liquid. When the chemical reaction within the reaction chamber 1 terminates... When the chemical reaction is complete, the lead screw 812, which is fixedly connected to the output end of the second motor 811, retracts the liquid separator 815, allowing the waste liquid to flow into the waste liquid tank 13 and then be discharged through the outlet 10 at the bottom center of the waste liquid tank 13. This effectively prevents the liquid from flowing directly into the waste liquid tank 13 while the chemical reaction is in progress. After the waste liquid is discharged, the replaceable sieve plate 82 is pulled out through the bar slider 825 using the handle 821, and the waste residue precipitated on the inner surface of the sieve plate is poured out. The replaced sieve plate 82 is then replaced with a cleaned one, making the sieve plate that was originally irreplaceable inside the instrument replaceable as needed. This also prevents the filter residue precipitated inside the instrument from becoming impossible to clean due to repeated use.
