Technical Field
[0001] This utility model relates to the technical field of metallurgical dust treatment equipment, specifically an integrated device for collecting and purifying metallurgical dust. Background Technology
[0002] In the metallurgical production process, a large amount of dust containing various harmful substances is generated. If it is not effectively treated, it will not only cause serious environmental pollution, but also endanger the health of operators. Therefore, dust collection and purification devices are needed to collect and purify the dust. At present, existing dust collection and purification devices only use a single filter to purify and filter the dust. A single filter cannot achieve graded filtration of dust. Fine dust may penetrate the filter, resulting in the purified gas still containing pollutants, thus making the overall purification effect poor.

The filter unit includes an air inlet pipe, an air inlet fan, a connecting pipe, an air outlet pipe, an exhaust pipe, a fixing ring, and a filter screen. In the above structure, dust is filtered only through the filter screen. In practical applications, it is impossible to achieve graded filtration of dust. Fine dust may penetrate the filter screen, resulting in the purified gas still containing pollutants. That is, the problem of poor dust purification effect mentioned above exists. Therefore, we need to propose an integrated device for metallurgical dust collection and purification. Utility Model Content

[0023] 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.
[0024] Please see Figure 1-5 This utility model provides a technical solution:
[0025] An integrated device for collecting and purifying metallurgical dust includes: a collection box 1; a spraying mechanism 2 for performing preliminary spraying purification of dust, wherein the spraying mechanism 2 is disposed inside the collection box 1; a first connecting pipe 3 connected to one side of the collection box 1; and a filtering mechanism 4 for performing multi-stage filtration purification of dust, wherein the filtering mechanism 4 is connected to the collection box 1 through the first connecting pipe 3.
[0026] With the arrangement of collection box 1, spray mechanism 2, first connecting pipe 3, and filter mechanism 4, the spray mechanism 2 in collection box 1 achieves preliminary spray purification of metallurgical dust, effectively removing large dust particles and water-soluble pollutants, reducing the subsequent filtration load. In conjunction with the filter mechanism 4 connected through the first connecting pipe 3, it can specifically intercept fine dust and harmful particles of different sizes, solving the problem of poor purification effect of traditional single filtration, thereby improving the overall purification efficiency and precision.
[0027] Specifically, the filtration mechanism 4 includes a first filter box 41, two sets of filter screens 42, a second connecting pipe 43, a second filter box 44, and two sets of electrode plates 45. The first filter box 41 is connected to one end of the first connecting pipe 3. Both sets of filter screens 42 are installed inside the first filter box 41. One end of the second connecting pipe 43 is connected to one side of the first filter box 41, and the other end of the second connecting pipe 43 is connected to one side of the second filter box 44. The two sets of electrode plates 45 are respectively located at the inner top and inner bottom of the second filter box 44.
[0028] With the arrangement of a first filter box 41, two sets of filter screens 42, a second connecting pipe 43, a second filter box 44, and two sets of electrode plates 45, the pre-purified gas rises and enters the first filter box 41 through the first connecting pipe 3. The first filter box 41 is equipped with two sets of filter screens 42. The filter screen 42 near the first connecting pipe 3 is used to intercept large-diameter dust particles, and the other set of filter screens 42 is used to intercept small-diameter dust particles, thereby achieving graded filtration and purification. The filtered gas then enters the second filter box 44 through the second connecting pipe 43. The two sets of electrode plates 45 at the top and bottom of the second filter box 44 form electrostatic adsorption through a high-voltage electric field, causing fine dust particles to become charged and adsorbed on the electrode plates 45, thereby deeply purifying fine dust particles and further improving the gas purification effect.
[0029] The bottom of the first filter box 41 and the second filter box 44 are fixedly installed with support bases 5, and one side of the support base 5 is fixedly connected to one side of the collection box 1.
[0030] The support base 5 enhances the structural stability of the first filter box 41 and the second filter box 44, ensuring the reliability and safety of the equipment during long-term operation.
[0031] Specifically, two sets of filter screens 42 are fixedly installed on both sides of each of them, and two sets of snap-fit slots 7 are opened on both sides of the inside of the first filter box 41 for snap-fitting of the snap-fit blocks 6.
[0032] With the snap-fit block 6 and snap-fit groove 7, the filter screen 42 is snapped into the snap-fit groove 7 of the first filter box 41 via the snap-fit block 6. The snap-fit installation structure facilitates the quick disassembly and replacement of the filter screen 42, and can clean or replace the clogged filter screen in a timely manner to maintain filtration efficiency.
[0033] In a further preferred embodiment, a sealing cover 8 is fixedly installed on the top of the two sets of filter screens 42, and the inner wall of the sealing cover 8 is adapted to the outer wall of the first filter box 41. Two sets of limiting blocks 9 are fixedly installed on both sides inside the sealing cover 8, and two sets of limiting grooves 10 are respectively opened on both sides of the first filter box 41 for the limiting blocks 9 to engage.
[0034] With the sealing cover 8, the limiting block 9, and the limiting groove 10, the sealing cover 8 tightly covers the top of the first filter box 41, which can effectively prevent dust from leaking from the top gap during the filtration process, avoid unpurified dust from being directly discharged into subsequent processes or escaping into the environment, and ensure the integrity of the purification effect. The limiting block 9 inside the sealing cover 8 engages with the limiting groove 10 of the first filter box 41, further enhancing the sealing performance of the sealing cover 8, thereby ensuring that the two sets of filter screens 42 are firmly installed inside the first filter box 41.
[0035] Specifically, the spraying mechanism 2 includes a storage tank 21, a suction pipe 22, a water pump 23, a delivery pipe 24, a spraying plate 25, and multiple sets of spray nozzles 26. The storage tank 21 is fixedly installed on one side of the collection tank 1. The water pump 23 can be a CDLF type vertical multistage centrifugal pump. The water pump 23 is fixedly installed on the top of the collection tank 1, and the water inlet of the water pump 23 is connected to the inside of the storage tank 21 through the suction pipe 22. One end of the delivery pipe 24 is connected to the water outlet of the water pump 23, and the other end of the delivery pipe 24 passes through the collection tank 1 and is connected to the top of the spraying plate 25. The bottom of the spraying plate 25 is arranged in a rectangular array and connected to multiple sets of spray nozzles 26.
[0036] With the arrangement of a storage tank 21, a suction pipe 22, a water pump 23, a delivery pipe 24, a spray plate 25, and multiple sets of nozzles 26, the water pump 23 draws the purified liquid from the storage tank 21 through the suction pipe 22, and then delivers it to the spray plate 25 through the delivery pipe 24. The multiple sets of nozzles 26 form an atomized spray, thereby achieving a uniform atomized spray effect. This allows the spray liquid to fully contact the dust, thus efficiently removing large particles of dust and water-soluble pollutants. The rectangular array of nozzles 26 can expand the spray coverage area, thereby improving the initial purification effect.
[0037] The bottom of the collection box 1 is fixedly equipped with a flow guide seat 11, and the flow guide seat 11 is inclined.
[0038] With the setting of the guide seat 11, the inclined guide seat 11 can guide the sewage and dust generated by the spray to flow to the sewage pipe 13, so as to facilitate the centralized discharge of sewage and avoid accumulation in the collection box 1.
[0039] Specifically, one side of the collection box 1 is connected to the feed pipe 12, and the other side of the collection box 1 is connected to the drain pipe 13. One side of the second filter box 44 is connected to the air outlet pipe 14.
[0040] With the installation of feed pipe 12, drain pipe 13 and vent pipe 14, feed pipe 12 can be connected to the dust discharge device to ensure that dust enters the collection box 1 smoothly. Drain pipe 13 is located at the bottom of one side of the collection box 1 to facilitate the discharge of sprayed wastewater. Vent pipe 14 facilitates the discharge of purified gas. The layout of each pipe makes the dust collection, purification and discharge process smooth, improving the practicality and environmental friendliness of the device.
[0041] Working principle: When this utility model is used, metallurgical dust enters the collection box 1 through the feed pipe 12. The water pump 23 is started, and the water pump 23 draws out the purification liquid in the storage tank 21 through the liquid extraction pipe 22, and then transports it to the spray plate 25 through the conveying pipe 24. Multiple sets of nozzles 26 form atomized spray, and the spray liquid comes into full contact with the dust, so that large dust particles and water-soluble pollutants are wetted and settled. The gas after preliminary purification flows upward, while the liquid containing impurities collects at the bottom of the collection box 1 along the inclined surface of the guide seat 11 and is discharged through the sewage pipe 13.
[0042] After preliminary purification, the gas rises and enters the first filter box 41 through the first connecting pipe 3. The first filter box 41 is equipped with two sets of filter screens 42. The filter screen 42 near the first connecting pipe 3 is used to intercept large-diameter dust particles, and the other set of filter screens 42 is used to intercept small-diameter dust particles, thereby achieving graded filtration and purification.
[0043] The filtered gas then enters the second filter box 44 through the second connecting pipe 43. The second filter box 44 is equipped with two sets of electrode plates 45. The two sets of electrode plates 45 form a high-voltage electric field, which charges the passing fine dust particles and adsorbs them onto the electrode plates 45, further removing the micro dust and ensuring deep purification of the gas. Finally, the purified gas is discharged through the gas outlet pipe 14.
