Description

Technical Field

[0001] This utility model belongs to the field of medium-frequency electric furnace technology, specifically a dust collection device for medium-frequency electric furnaces. Background Technology

[0002] Dust collection equipment for medium-frequency electric furnaces refers to specialized equipment for collecting and purifying dust generated during the smelting and heating processes of medium-frequency electric furnaces. Its core function is to separate dust particles from dust-laden gas through physical, chemical, or mechanical means, so that the emitted gas meets environmental protection standards, while also achieving dust recovery or safe disposal.

[0003] Existing dust collection equipment for medium-frequency electric furnaces can achieve a dust collection efficiency of over 99%, meeting stringent environmental standards.

[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] like Figures 1 to 6 As shown, this utility model provides a dust collection device for a medium-frequency electric furnace, including a furnace body 1. A collection box 2 is provided on the right side of the outer wall of the furnace body 1, and a collection mechanism 3 is provided on the outer wall of the collection box 2. The collection mechanism 3 is used to collect dust. A furnace cover 4 is installed on the top wall of the furnace body 1, and a fixing mechanism 5 is provided on the top of the furnace cover 4. The fixing mechanism 5 is used to fix the pipe to the furnace cover 4. The collection mechanism 3 includes a housing 301, which is located on the left side of the outer wall of the collection box 2. A motor 302 is fixedly connected to the inner bottom wall of the housing 301. A rotating shaft 303 is fixedly connected to the output end of the motor 302. A fan blade 304 is fixedly connected to the top end of the rotating shaft 303. A circular groove 307 is opened inside the housing 301, and the fan blade 304 is rotatably connected inside the circular groove 307. The left side of the inner wall of the circular groove 307 is connected to a connecting... Pipe 305 and the inner right side of the circular groove 307 are connected to a connecting pipe 306. The end of the connecting pipe 306 is connected to the lower left side of the outer wall of the collection box 2. The inside of the collection box 2 is equipped with a spray assembly 308. The spray assembly 308 includes a fixing plate 3081, which is fixedly connected to the lower front side of the outer wall of the collection box 2. A water storage tank 3082 is installed on the left side of the top wall of the fixing plate 3081. A water pump 3083 is fixedly connected to the right side of the top wall of the fixing plate 3081. The left side of the outer wall of the water pump 3083 is connected to the right side of the outer wall of the water storage tank 3082. The output end of the water pump 3083 is fixedly connected to a diversion pipe 3084. Multiple nozzles 3085 are equidistantly installed on the bottom outer wall of the diversion pipe 3084. The diversion pipe 3084 is fixedly connected to the inner top wall of the collection box 2.

[0025] The collecting mechanism 3 is responsible for collecting dust, while the fixing mechanism 5 ensures the stable fixation of the pipe on the furnace cover 4. The motor 302 drives the fan blade 304 to rotate in the circular groove 307. The dust and flue gas in the furnace body 1 are sucked into the shell 301 through the connecting pipe 1 305, and then transmitted to the collecting box 2 through the connecting pipe 2 306. At the same time, the water pump 3083 draws water from the water storage tank 3082 and sprays it out from the nozzle 3085 in the form of a mist through the diversion pipe 3084. These mist water flows collide with the dust particles in the rising flue gas due to inertial force and agglomerate and settle, thereby achieving gas-solid separation. The purified gas is discharged, while the dust is deposited at the bottom of the collecting box 2 with the wastewater, completing the entire dust removal process.

[0026] The fixing mechanism 5 includes a semicircular block 501, which is located on the right side of the top wall of the furnace cover 4. A second semicircular block 502 is located on the left side of the outer wall of the first semicircular block 501. Multiple springs 503 are equidistantly installed on adjacent sides of the outer walls of both the first and second semicircular blocks 501 and 502. Clamping blocks 504 are installed at the ends of the springs 503. Bolts 505 are threaded to the front and rear ends of the left side of the outer walls of both the first and second semicircular blocks 501 and 502. Nuts 506 are threaded to the ends of the bolts 505. A connection is made in the middle of the top wall of the furnace cover 4. A fixed tube 507 engages with a connecting tube 305. The connecting tube 305 is located on the adjacent side of the outer wall of the two clamping blocks 504. A sliding assembly 508 is provided on the top of the furnace cover 4. The sliding assembly 508 includes a slider 5081. Both sliders 5081 are located on the left and right sides of the top wall of the furnace cover 4. The inner wall of the slider 5081 is slidably connected to a groove 5082. The left groove 5082 is fixedly connected to the middle of the bottom wall of the semicircular block 502, and the right groove 5082 is fixedly connected to the middle of the bottom wall of the semicircular block 501.

[0027] By engaging the fixing pipe 507 with the connecting pipe 305, a sealing effect is achieved. Then, the semicircular blocks 501 and 502 move closer to each other, while the sliders 5081 of the semicircular blocks 501 and 502 slide in the groove 5082. By locking the bolts 505 and nuts 506, the semicircular blocks 501 and 502 are fixed together. At this time, the springs 503 on the adjacent sides are under pressure, causing the clamping blocks 504 to elastically clamp the connecting pipe 305 from both sides, thereby ensuring that the pipe is firmly fixed on the furnace cover 4 and effectively preventing flue gas leakage.

[0028] Among them, a fixing plate 6 is fixedly connected to the lower left side of the outer wall of the collection box 2, and the shell 301 is fixedly connected to the top wall of the fixing plate 6.

[0029] The fixing plate 26 is used to provide a stable mounting support for the housing 301.

[0030] Among them, a square groove 7 is provided on the upper right side of the outer wall of the collection box 2, and a filter screen 8 is installed on the inner side of the square groove 7.

[0031] The square channel 7 is used to install the filter screen 8. The filter screen 8 is used to intercept solid dust particles in the gas and at the same time block water vapor to a certain extent, so as to prevent incompletely settled dust from being discharged with the gas, thereby realizing gas-dust separation, ensuring the cleanliness of the discharged gas, and improving the environmental protection effect and dust removal efficiency of the dust collection equipment.

[0032] Among them, a square groove 9 is provided on the lower right side of the outer wall of the collection box 2, and a collection box 10 is slidably connected to the inner wall of the square groove 9.

[0033] Dust mixes with water to form mud or particles, which settle to the bottom of collection box 2 under gravity. When cleaning is needed, it can be directly pulled out from square groove 2 9 without disassembling the entire collection box 2, simplifying the maintenance process.

[0034] The collection box 2 has a cover 11 on the front side of its outer wall, and the cover 11 is installed on the left side of the top wall of the water storage tank 3082.

[0035] The water tank 3082 can be easily replenished with clean water by opening the cover 11, or the water level in the water tank 3082 can be checked.

[0036] Working principle and usage process of this utility model:

[0037] Motor 302 drives fan blade 304 to rotate in circular groove 307. Dust and flue gas in furnace body 1 are drawn into shell 301 through pipe on furnace cover 4 via connecting pipe 1 305, and then transferred to collection box 2 via connecting pipe 2 306. At the same time, water pump 3083 draws water from water storage tank 3082 and sprays a mist of water from nozzle 3085 through diversion pipe 3084. The water collides with the dust particles in the rising flue gas, causing them to agglomerate and settle, thus achieving gas-solid separation. The purified gas is discharged, and the dust is deposited at the bottom of collection box 2 with the wastewater, thereby completing the dust removal process.

[0038] The fixing pipe 507 and the connecting pipe 305 are engaged to achieve a seal. Then, the semicircular blocks 501 and 502 are brought closer together. At the same time, the sliders 5081 of the semicircular blocks 501 and 502 slide in the groove 5082. The semicircular blocks 501 and 502 are locked by bolts 505 and nuts 506. At this time, the springs 503 on the adjacent sides are compressed, which drives the clamping blocks 504 to elastically clamp the connecting pipe 305 from both sides, thereby fixing the pipe firmly on the furnace cover 4 and preventing flue gas leakage.
