Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater filtration device for iron and steel smelting. Background Technology

[0002] Wastewater filtration equipment for iron and steel smelting is a core device for removing impurities from wastewater generated during the iron and steel production process. It removes pollutants such as suspended solids, heavy metals, oils, and colloids from the wastewater through physical, chemical, or membrane separation technologies, so that the water quality meets discharge standards or reuse requirements.

[0003] Sand filters are filtration devices used in the initial treatment process of wastewater from iron and steel smelting. They mainly utilize the porous structure of granular filter media such as quartz sand to remove suspended solids and colloidal impurities from wastewater through interception and adsorption. However, iron and steel smelting wastewater contains a relatively large amount of colloids and suspended solids. In the actual filtration process, these impurities can easily accumulate between the inlet pipe and the quartz sand filter media. The accumulation of colloidal impurities and suspended solids can easily clog the inlet pipe and the quartz sand filter layer, thus hindering the rapid treatment of wastewater. Utility Model Content

[0004] This utility model proposes a wastewater filtration device for steel smelting, which addresses the problem that steel smelting wastewater contains a relatively large amount of colloids and suspended solids, which easily accumulate between the inlet pipe and the quartz sand filter media. The accumulated colloidal impurities and suspended solids can easily clog the inlet pipe and the quartz sand filter layer, thus hindering the rapid treatment of wastewater.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wastewater filtration device for iron and steel smelting, comprising a tank body, the interior of which is filled with quartz sand filter media, a packing tube welded to the middle of the outer surface of the tank body, an outlet pipe welded to the bottom of the tank body, an inlet pipe provided at the top of the tank body, and an auxiliary device provided between the inlet pipe and the tank body. The auxiliary device performs preliminary filtration of the wastewater from iron and steel smelting by setting an auxiliary box with a first filter plate, and performs preliminary filtration and removal of colloids and suspended solids.

[0006] The effect achieved by the above components is as follows: by setting up an auxiliary box with a first filter plate, the first filter plate can filter the wastewater from steel smelting, perform preliminary filtration and enrichment of large colloids and suspended solids, and clean up the enriched impurities. This helps to prevent the accumulation of colloidal impurities and suspended solids from clogging the inlet end of the water inlet pipe, thereby facilitating the rapid treatment of sewage.

[0007] Preferably, the auxiliary device includes an auxiliary box, which is fixedly installed on the top of the tank. The water inlet pipe is welded to one side of the auxiliary box. The inner wall of the auxiliary box is connected to both the water inlet pipe and the inner wall of the tank. A filter plate is slidably installed on the inner wall of the auxiliary box. A round rod is fixedly installed at the middle of the top of the filter plate. A cover is slidably installed on the outer surface of the round rod. The cover is located on the top of the auxiliary box, and one end is inserted into the inner wall of the auxiliary box.

[0008] The effect achieved by the above components is as follows: when the cover is inserted into the inner wall of the auxiliary box and the round rod is pushed, the first filter plate moves along the inner wall of the auxiliary box until the first filter plate abuts against the bottom of the inner wall of the auxiliary box. Then the first filter plate can filter the wastewater entering the auxiliary box through the water inlet pipe. At the same time, the cover is detachable, which makes it easy to clean impurities directly and helps to prevent impurities from clogging the water inlet pipe and the quartz sand filter layer.

[0009] Preferably, a connecting plate is fixedly installed at the top of the round rod, a spring is fixedly installed at the bottom of the connecting plate, one end of the spring is fixedly installed at the top of the cover, and the spring is sleeved on the outer surface of the round rod.

[0010] The effect achieved by the above components is as follows: when the first filter plate is pushed down, the connecting plate will squeeze the spring, causing the spring to deform. When the external force applied to the connecting plate is removed, the spring will reset and drive the first filter plate to automatically move away from the bottom of the auxiliary box inner wall, and carry the impurities from the bottom of the auxiliary box to the top of the box, making it easier to clean the impurities.

[0011] Preferably, a silicone ring is fixedly installed on the outer surface of the first filter plate, the top of the silicone ring extends beyond the top of the first filter plate, and the outer surface of the silicone ring is in contact with the inner wall of the auxiliary box.

[0012] The effect achieved by the above-mentioned components is as follows: by setting the silicone ring, it can replace the outer surface of the first filter plate and abut against the inner wall of the auxiliary box. Under the action of the first filter plate, it can also clean the impurities attached to the inner wall of the auxiliary box. At the same time, the height of the silicone ring is higher than that of the first filter plate, which makes it easier to accommodate and block impurities, and helps to prevent impurities from entering the water inlet pipe.

[0013] Preferably, a second filter plate is installed on the inner wall of the top of the tank, and the second filter plate is disposed at the bottom of the first filter plate.

[0014] The effect achieved by the above components is as follows: by setting a second filter plate, the second filter plate can improve the filtration capacity of the first filter plate for impurities. At the same time, when the first filter plate is far away from the tank, the second filter plate can still screen impurities, which helps to prevent large particles of impurities from entering the tank.

[0015] Preferably, a rubber ring is fixedly installed at the bottom of the cover, and the outer surface of the rubber ring abuts against the inner wall of the auxiliary box.

[0016] The effect achieved by the above components is that by setting a rubber ring, the rubber ring can seal between the cover and the inner wall of the auxiliary box, which helps to prevent sewage from overflowing from between the cover and the inner wall of the auxiliary box.

[0017] Preferably, threaded pins are symmetrically fixedly installed at the bottom of the connecting plate, and round hole blocks are symmetrically fixedly installed on both sides of the outer surface of the auxiliary box. The threaded pins are inserted into the inner walls of the cover and the round hole blocks, and two nuts are threadedly connected to the outer surface of the threaded pins. The two nuts are respectively located on the side of the cover and the round hole blocks that are far apart.

[0018] The effect achieved by the above components is as follows: the first filter plate is inserted into the interior of the auxiliary box, and the cover is inserted into the inner wall of the auxiliary box. Then, the connecting plate is pressed down, which moves the first filter plate connected to the round rod downward. The connecting plate and the cover will compress the spring, causing the spring to deform until the bottom of the first filter plate abuts against the top of the second filter plate. At this time, the threaded pin is also fully inserted into the inner wall of the cover and the round hole block. By rotating the two nuts, one side of each nut abuts against one side of the round hole block and the cover, the cover and the first filter plate can be fixed. This helps to prevent the cover from falling out of the auxiliary box, which would cause sewage to overflow or the first filter plate to move away from the tank and fail to filter the wastewater.

[0019] Preferably, rubber pads are fixedly installed on the adjacent sides of the two nuts, and the threaded pin is inserted inside the two rubber pads.

[0020] The effect achieved by the above-mentioned components is that by setting a rubber pad, one side of the nut can be replaced by one side of the round hole block or one side of the cover, and the friction between the nut and the round hole block or cover can be increased, making the nut less likely to loosen.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up an auxiliary box with a first filter plate, the first filter plate can filter the wastewater from steel smelting, perform preliminary filtration and enrichment of large-particle colloids and suspended solids, and clean up the enriched impurities. This helps prevent the accumulation of colloidal impurities and suspended solids from clogging the inlet end of the water inlet pipe, thereby facilitating the rapid treatment of sewage.

[0024] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a wastewater filtration device for iron and steel smelting, including a tank 1. The interior of the tank 1 is filled with quartz sand filter media. A packing pipe 2 is welded to the middle of the outer surface of the tank 1. A water outlet pipe 3 is welded to the bottom of the tank 1. A water inlet pipe 4 is provided at the top of the tank 1. An auxiliary device 5 is provided between the water inlet pipe 4 and the tank 1. The auxiliary device 5 performs preliminary filtration of the wastewater from iron and steel smelting by setting an auxiliary box 51 with a first filter plate 52, and performs preliminary filtration and removal of colloids and suspended solids. By setting an auxiliary box 51 with a first filter plate 52, the first filter plate 52 can filter the wastewater from iron and steel smelting, perform preliminary filtration and enrichment of large particles of colloids and suspended solids, and clean up the enriched impurities. This helps to prevent the accumulation of colloidal impurities and suspended solids from clogging the water inlet pipe 4 and the quartz sand filter layer, thereby facilitating the rapid treatment of wastewater.

[0025] Reference Figures 2-4As shown, the auxiliary device 5 includes an auxiliary box 51, which is fixedly installed on the top of the tank 1. An inlet pipe 4 is welded to one side of the auxiliary box 51. The inner wall of the auxiliary box 51 is connected to both the inlet pipe 4 and the inner wall of the tank 1. A first filter plate 52 is slidably installed on the inner wall of the auxiliary box 51. A round rod 53 is fixedly installed at the center of the top of the first filter plate 52. A cover 54 is slidably installed on the outer surface of the round rod 53. The cover 54 is located on the top of the auxiliary box 51, with one end inserted into the inner wall of the auxiliary box 51. Inserting the cover 54 into the inner wall of the auxiliary box 51 and pushing the round rod 53 causes the first filter plate 52 to move along the inner wall of the auxiliary box 51 until the first filter plate 52 abuts against the bottom of the inner wall of the auxiliary box 51. Then, the first filter plate 52 can filter the water entering through the inlet pipe 4. Wastewater in the auxiliary box 51 is filtered, and the cover 54 is removable, facilitating direct cleaning of impurities and preventing blockage between the inlet pipe 4 and the quartz sand filter layer. A connecting plate 55 is fixedly installed at the top of the round rod 53, and a spring 56 is fixedly installed at the bottom of the connecting plate 55. One end of the spring 56 is fixedly installed on the top of the cover 54. The spring 56 is sleeved on the outer surface of the round rod 53. When the first filter plate 52 is pushed down, the connecting plate 55 will squeeze the spring 56, causing the spring 56 to deform. When the external force applied to the connecting plate 55 is removed, the spring 56 will reset and automatically move the first filter plate 52 away from the bottom of the inner wall of the auxiliary box 51, and bring the impurities from the bottom of the auxiliary box 51 to the top of the box, making it easier to clean the impurities.

[0026] Reference Figure 2 and Figure 3 As shown, a silicone ring 57 is fixedly installed on the outer surface of the first filter plate 52. The top of the silicone ring 57 extends beyond the top of the first filter plate 52, and the outer surface of the silicone ring 57 is in contact with the inner wall of the auxiliary box 51. By setting the silicone ring 57, it can replace the outer surface of the first filter plate 52 to abut against the inner wall of the auxiliary box 51. Under the action of the first filter plate 52, it can also clean the impurities attached to the inner wall of the auxiliary box 51. At the same time, the height of the silicone ring 57 is higher than that of the first filter plate 52, which makes it easier to accommodate and block impurities, and helps to prevent impurities from entering the water inlet pipe 4. A second filter plate 58 is installed on the inner wall of the top of the tank 1. The second filter plate 58 is located at the bottom of the first filter plate 52. By setting the second filter plate 58, the second filter plate 58 can improve the filtration capacity of the first filter plate 52 for impurities. At the same time, when the first filter plate 52 is away from the tank 1, the second filter plate 58 can still screen impurities, which helps to prevent large particles of impurities from entering the interior of the tank 1.

[0027] Reference Figure 2 and Figure 4As shown, a rubber ring 59 is fixedly installed at the bottom of the cover 54. The outer surface of the rubber ring 59 abuts against the inner wall of the auxiliary box 51. By setting the rubber ring 59, the rubber ring 59 can seal the space between the cover 54 and the inner wall of the auxiliary box 51, which helps to prevent sewage from overflowing from the space between the cover 54 and the inner wall of the auxiliary box 51.

[0028] Reference Figures 2-4 As shown, threaded pins 510 are symmetrically fixedly installed on the bottom of the connecting plate 55, and round hole blocks 511 are symmetrically fixedly installed on both sides of the outer surface of the auxiliary box 51. The threaded pins 510 are inserted into the inner walls of the cover 54 and the round hole blocks 511. Two nuts 512 are threadedly connected to the outer surface of the threaded pins 510. The two nuts 512 are respectively located on the side of the cover 54 and the round hole blocks 511 that are far apart. The first filter plate 52 is inserted into the interior of the auxiliary box 51, and the cover 54 is inserted into the inner wall of the auxiliary box 51. Then, the connecting plate 55 is pressed down, which drives the first filter plate 52 connected to the round rod 53 to move downward. The connecting plate 55 and the cover 54 will compress the spring 56, causing the spring 56 to deform until the bottom of the first filter plate 52 abuts against the top of the second filter plate 58. At this time, the threaded pins 510 are also completely pressed down. The two nuts 512 are fully inserted into the inner walls of the cover 54 and the round hole block 511. By rotating the two nuts 512, one side of each nut 512 abuts against one side of the round hole block 511 and the cover 54, respectively. This fixes the cover 54 and the first filter plate 52, which helps prevent the cover 54 from detaching from the auxiliary box 51 and causing sewage to overflow, or the first filter plate 52 from moving away from the tank 1 and failing to filter wastewater. Rubber pads 513 are fixedly installed on the side of each nut 512 that is close to each other. Threaded pins 510 are inserted into the inside of the two rubber pads 513. By setting the rubber pads 513, one side of the nut 512 can abut against one side of the round hole block 511 or the cover 54, and the friction between the nut 512 and the round hole block 511 or the cover 54 can be increased, making it less likely for the nut 512 to loosen.

[0029] Working principle: Insert the first filter plate 52 into the auxiliary box 51 and insert the cover 54 into the inner wall of the auxiliary box 51, so that the outer surface of the rubber ring 59 abuts against the inner wall of the auxiliary box 51. Then, press the connecting plate 55 downward, causing the first filter plate 52 connected to the round rod 53 to move downward. The connecting plate 55 and the cover 54 will compress the spring 56, causing the spring 56 to deform until the bottom of the first filter plate 52 abuts against the top of the second filter plate 58. At this time, the threaded pin 510 is also fully inserted into the inner wall of the cover 54 and the round hole block 511. Rotate the two nuts 512 so that the rubber pads 513 on one side of the two nuts 512 abut against one side of the round hole block 511 and the cover 54, respectively. This will enable the cover 54 and the first filter plate 52 to be pressed down. The first filter plate 52 is fixed in place and can filter the wastewater from steel smelting, performing preliminary filtration and enrichment of large colloids and suspended solids. Rotating the nut 512 releases the nut 512 from limiting the cover 54 and the first filter plate 52. The spring 56 will reset and drive the first filter plate 52 to automatically move away from the bottom of the inner wall of the auxiliary box 51, and carry the impurities from the bottom of the auxiliary box 51 to the top of the box. When the first filter plate 52 moves upward, it will drive the silicone ring 57 to clean the impurities attached to the inner wall of the auxiliary box 51. At the same time, the height of the silicone ring 57 is higher than that of the first filter plate 52, which makes it easier to accommodate and block impurities, and helps to prevent impurities from entering the water inlet pipe 4. Opening the cover 54 allows the impurities to be cleaned.
