Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a dust removal device for a muck removal machine. Background Technology

[0002] Slag removers are key pieces of equipment in the metallurgical (such as steelmaking and molten iron pretreatment) and casting industries used to remove slag from the surface of molten metal. During slag removal operations, the high-temperature slag remover plate comes into contact with the molten slag, generating a large amount of dense, high-temperature, high-humidity fumes rich in fine particulate matter. These fumes erupt instantly and rapidly spread into the workshop, severely polluting the working environment and endangering the health of operators.

[0003] An existing dust removal device for a muck loader typically extracts and filters the dust generated during the muck loading operation. However, the collected dust is sticky and easily adheres to and accumulates in the pipes and on the filter plate surface, causing blockage of the pipes and filter plate openings, increasing the system's operating resistance and making maintenance work arduous. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal device for a slag remover, which has the functions of maintaining the temperature of the conveying dust pipeline, scraping and cleaning the surface of the filter plate, and preventing dust from caking in the pipeline and on the surface of the filter plate.

[0009] A further feature of this invention is that a suction hood is fixedly connected to the outside of the telescopic tube and to the outside of the slag remover body, and the insulation layer is fixedly connected to the outside of the slag remover body.

[0010] By adopting the above technical solution, the suction hood can be moved along with the bucket, thereby absorbing the smoke and dust generated by the bucket in a timely manner.

[0011] A further feature of this invention is that a high-pressure air pump is fixedly connected to the outside of the slag remover body, and the air outlet of the high-pressure air pump is fixedly connected to a blower nozzle that is fixedly connected to the suction hood via a connecting pipe.

[0012] A further feature of this invention is that the number of the blower nozzles is two and they are symmetrically distributed, with both blower nozzles located on the outer edge of the suction hood.

[0013] By adopting the above technical solution, the blower nozzle can use airflow to "blow" the escaping smoke and dust towards the air intake, preventing the smoke and dust from escaping from the air intake hood.

[0014] A further feature of this invention is that a water tank is fixedly connected to the top of the slag remover body, the outlet of the water tank is fixedly connected to the inlet of the water pump via a water pipe, the outlet of the water pump is fixedly connected to the diversion pipe via a water pipe, and a water spray hood is fixedly connected to the bottom of the diversion pipe.

[0015] By adopting the above technical solution, water can be easily delivered into the diversion pipe through the water pipe, and finally sprayed onto the surface of the conveyed material through the water spray hood, preventing smoke and dust from appearing during the material conveying process.

[0016] A further feature of this invention is that the number of water spray nozzles is seven and they are arranged in a linear array, and a water inlet pipe is fixedly connected to the top of the water tank.

[0017] By adopting the above technical solution, it is convenient to spray water onto the surface of the material through the spray hood to prevent the generation of smoke and dust, and to inject water into the water tank through the water inlet pipe. Attached Figure Description

Detailed Implementation

[0026] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] A dust removal device for a muck loader includes a muck loader body 1 and a driver's cab 2 fixedly connected inside the muck loader body 1. A filter box 3 is fixedly connected to the outside of the driver's cab 2. A telescopic tube 4 is fixedly connected inside the filter box 3. An insulation layer 5 is wrapped around the outside of the telescopic tube 4. An electric heating tape 6 is embedded in the insulation layer 5. A filter plate 7 is fixedly connected inside the filter box 3. A scraper 8 is slidably connected inside the filter box 3. The scraper 8 abuts against the filter plate 7 and the bottom wall of the filter box 3. A sliding column 9 is fixedly connected to the outside of the scraper 8 and slidably connected to the inside of the filter box 3. A microporous polytetrafluoroethylene film is coated on the surface of the filter plate 7 to achieve surface filtration. Dust is trapped on the surface of the filter plate 7 and cannot enter its interior, fundamentally avoiding caking and achieving excellent dust removal effect. The filter plate has a filter pore size of 0.5um. The telescopic tube 4 is made of stainless steel.

[0028] When the slag loader 1's bucket scoops up loose materials such as soil, sand, gravel, lime, and coal, it generates a large amount of dust. At this time, the blower 12 is started, and the blower 12 sucks the dust into the suction hood 13. Then, it enters the filter box 3 through the telescopic pipe 4 for filtration and collection. The insulation layer 5 on the outside of the telescopic pipe 4 keeps the sucked dust warm, and the electric heating cable 6 heats the dust to prevent the high-temperature and high-humidity dust from condensing on the inner wall of the telescopic pipe 4 when it encounters cold air, thus clogging the inside of the telescopic pipe 4 and making cleaning work quite arduous. After entering the filter box 3, the filter plate 7 filters it, and the dust is left on the surface of the filter plate. Then, by pulling the handle 10, the handle 10 drives the sliding column 9 to slide, and the sliding column 9 drives the scraper 8 to slide, scraping off the condensed dust on the surface of the filter plate 7. The opening and closing cover 11 is opened to scrape the dust that has fallen on the bottom wall of the filter box 3 out of the filter box 3.

[0029] Specifically, refer to Figure 5 A handle 10 is fixedly connected to the outside of the sliding column 9, and a sealing gasket that contacts the filter box 3 is provided on the outside of the sliding column 9.

[0030] In a specific implementation, by pulling the handle 10, the handle 10 drives the sliding column 9 to slide, and the sliding column 9 drives the scraper 8 to slide, scraping off the condensed dust on the surface of the filter plate 7, and at the same time scraping the dust that falls on the bottom wall of the filter box 3 out of the filter box 3. The sealing gasket prevents air leakage between the filter box 3 and the sliding column 9, which would affect the filtration of smoke and dust.

[0031] Specifically, refer to Figure 2 The filter box 3 has an internal hinged cover 11 with a sealing gasket between the cover 11 and the filter box 3. The outside of the cab 2 is fixedly connected to a fan 12 whose air inlet is fixedly connected to the filter box 3.

[0032] In a specific implementation, the opening and closing cover 11 is opened, and the scraper 8 slides to scrape off the condensed dust on the surface of the filter plate 7 and scrape out the dust that falls on the bottom wall of the filter box 3. The fan 12 is started so that the dust at this time when the slag remover body 1 is working enters the filter box 3 through the suction hood 13 and the telescopic pipe 4 for filtration and collection. The sealing gasket prevents air leakage between the opening and closing cover 11 and the filter box 3.

[0033] Specifically, refer to Figure 3 and Figure 4 The outer side of the telescopic pipe 4 is fixedly connected to the suction hood 13, which is also fixedly connected to the outer side of the slag remover body 1. The insulation layer 5 is also fixedly connected to the outer side of the slag remover body 1.

[0034] In a specific implementation, the blower 12 is started so that the dust generated during the operation of the slag remover body 1 enters the filter box 3 through the suction hood 13 and the telescopic pipe 4 for filtration and collection. The suction hood 13 moves with the movement of the bucket of the slag remover body 1, thereby collecting the dust generated during the operation of the bucket in a timely manner.

[0035] Specifically, refer to Figure 3 A high-pressure air pump 14 is fixedly connected to the outside of the slag remover body 1. The air outlet of the high-pressure air pump 14 is fixedly connected to a blower nozzle 16 that is fixedly connected to the suction hood 13 via a connecting pipe 15.

[0036] In a specific implementation, the high-pressure air pump 14 is started, and the high-pressure air pump 14 compresses the air and delivers it into the connecting pipe 15. The blower nozzle 16 forms an air curtain to guide the smoke and dust to the suction hood 13.

[0037] Specifically, refer to Figure 3 There are two blower nozzles 16, which are symmetrically distributed, and both blower nozzles 16 are located on the outer edge of the suction hood 13.

[0038] In a specific implementation, the blower nozzle 16 compresses the air and uses the airflow to "blow" the escaping smoke and dust towards the air intake, preventing the smoke and dust from escaping from the air intake hood 13.

[0039] Specifically, refer to Figure 3 and Figure 6 A water tank 17 is fixedly connected to the top of the slag remover body 1. The outlet of the water tank 17 is fixedly connected to the inlet of the water pump 18 through a water pipe. The outlet of the water pump 18 is fixedly connected to the diversion pipe 19 through a water pipe. A water spray cover 20 is fixedly connected to the bottom of the diversion pipe 19.

[0040] In a specific implementation, the water pump 18 is started, the water pump 18 draws water from the water tank 17 into the water pipe, and sends the water into the diversion pipe 19 through the water pipe, and finally sprays it onto the surface of the conveyed material through the water spray hood 20 to prevent dust from appearing during the material conveying process.

[0041] Specifically, refer to Figure 6 There are seven water spray nozzles 20 arranged in a linear array, and the top of the water tank 17 is fixedly connected to a water inlet pipe.

[0042] In a specific embodiment, water inside the water tank 17 is sprayed onto the material surface through the water spray hood 20 to prevent the generation of smoke and dust, and water is injected into the water tank 17 through the water inlet pipe.
