Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically a front-end treatment device suitable for alternative fuel dust collection equipment. Background Technology

[0002] With escalating global environmental problems, carbon dioxide emission reduction has become an urgent task. Alternative fuel technologies are supported by governments worldwide due to their ability to reduce emissions and generate economic benefits. Meanwhile, by improving furnace technology, waste can be converted into energy, achieving both environmental and economic benefits.

[0003] In the production and processing of alternative fuels, the collection and treatment of dust and fine particulate matter are crucial steps. Traditional dust collection equipment often faces problems such as material blockage, airflow diffusion, and low dust collection efficiency when handling dust-laden airflow. These problems not only affect the normal operation of the equipment but also increase maintenance costs and reduce production efficiency.

[0004] Specifically, traditional dust collection equipment lacks an effective material filtration mechanism in the front-end processing stage, allowing large pieces of material and clumps of flocculent matter to easily enter the back-end equipment, causing blockages and bag clogging. This not only affects the dust collection efficiency but may also lead to equipment damage and downtime.

[0005] Based on this, a front-end treatment device suitable for alternative fuel dust collection equipment is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this utility model is to provide a front-end treatment device suitable for alternative fuel dust collection equipment, so as to solve the problem that the front-end treatment of traditional dust collection equipment in the background technology lacks effective filtration, which often leads to large pieces of material and flocculent matter clogging the back-end equipment, causing blockage and bag clogging.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A front-end treatment device for dust collection equipment for alternative fuels includes a dust collection hood. Symmetrically fixed horn-shaped openings are fixed on both sides of the upper end of the dust collection hood. A negative pressure dust collection pipe is fixedly installed on the upper end of the horn-shaped openings. Rotating rollers are symmetrically rotatably installed on the left and right sides inside the dust collection hood. Polyurethane woven mesh belts are fitted on the outer walls of the two rotating rollers. Several ventilation holes are opened on the polyurethane woven mesh belts.

[0009] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0010] In one alternative: a motor is installed on the outer wall of the dust collection hood, the output end of the motor extends into the interior of the dust collection hood and is fixedly connected to a rotating roller, a scraping baffle is fixed on the left side inside the dust collection hood, the scraping baffle is located at the lower end of the polyurethane woven mesh belt, and the upper end of the scraping baffle is in contact with the surface of the polyurethane woven mesh belt.

[0011] In one alternative: a shell support keel is fixedly installed on the outer wall of the dust collection hood, and several legs are fixed at the lower end of the shell support keel.

[0012] In one alternative: the inner diameter of the flared opening gradually decreases from bottom to top.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses the ventilation holes on the polyurethane woven mesh belt to prevent large pieces of material from entering the downstream equipment and causing blockage and clogging. At the same time, the operation of the motor-driven rotating drum and the polyurethane woven mesh belt, as well as the design of the scraper baffle, make it easy to scrape off the material attached to the mesh belt, thereby avoiding the problem of material clogging the ventilation holes.

[0015] 2. This utility model, through the design of the horn-shaped constriction, makes the airflow entering the dust collection hood more concentrated and smooth, reduces the diffusion and eddy phenomenon of airflow, thereby improving the dust collection efficiency. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-4As shown, a front-end treatment device for dust collection equipment for alternative fuels includes a dust collection hood 3. The dust collection hood 3 has symmetrically fixed horn-shaped openings 2 on both sides of its upper end. A negative pressure dust collection pipe 1 is fixedly installed on the upper end of the horn-shaped openings 2. Rotating rollers 6 are symmetrically rotated on the left and right sides inside the dust collection hood 3. Polyurethane woven mesh belts 7 are fitted on the outer walls of the two rotating rollers 6. Several ventilation holes 10 are opened on the polyurethane woven mesh belts 7.

[0023] In this embodiment, the device is installed at the dust collection point. The dust collection hood 3 is then welded to the dust collection equipment through openings. The upper negative pressure dust collection pipe 1 is connected to the negative pressure duct of the dust collection equipment. After the upstream dust collection equipment starts, a large amount of dust-laden gas carries a small amount of lightweight material into the dust collection hood 3. The vent holes 10 on the polyurethane woven mesh belt 7 can filter out larger materials and clumps of flocculent matter. The gas containing fine dust enters the negative pressure dust collection pipe 1 and then proceeds to the downstream dust collection equipment for processing. The device is positioned at the front end of the dust collection equipment, effectively preventing large pieces of material from clogging and causing bag jamming.

[0024] In one embodiment, such as Figure 1 and Figure 3 As shown, a motor 9 is installed on the outer wall of the dust collection hood 3. The output end of the motor 9 extends into the interior of the dust collection hood 3 and is fixedly connected to a rotating roller 6. A scraping baffle 8 is fixed on the left side inside the dust collection hood 3. The scraping baffle 8 is located at the lower end of the polyurethane woven mesh belt 7, and the upper end of the scraping baffle 8 is in contact with the surface of the polyurethane woven mesh belt 7.

[0025] By setting the motor 9 to drive the rotating drum 6 to rotate, the polyurethane woven mesh belt 7 starts to run. When the polyurethane woven mesh belt 7 is running, the scraper 8 scrapes off the material attached to the polyurethane woven mesh belt 7, thereby preventing the material from clogging the air vents 10 of the polyurethane woven mesh belt 7 and affecting subsequent dust collection.

[0026] In one embodiment, such as Figure 1 As shown, a shell support keel 4 is fixedly installed on the outer wall of the dust collection hood 3, and several support legs 5 are fixed at the lower end of the shell support keel 4.

[0027] By setting up a shell support keel 4, the overall stability of the dust collection hood 3 can be effectively enhanced, preventing it from deforming or being damaged when subjected to external forces, and ensuring its safety and reliability during long-term operation.

[0028] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the inner diameter of the horn-shaped constriction 2 gradually decreases from bottom to top.

[0029] When dust-laden gas enters through the dust collection hood 3, the tapering design of the horn-shaped constriction 2 reduces airflow diffusion, allowing the airflow to flow more concentratedly towards the negative pressure dust collection duct 1. This concentration effect helps reduce eddies and turbulence in the airflow, thereby reducing the material escape rate and improving dust collection efficiency.

[0030] The above embodiment discloses a front-end treatment device suitable for alternative fuel dust collection equipment. The device is installed at the dust collection point and fixed to the dust collection equipment by the support leg 5. Then, the dust collection hood 3 is welded to the dust collection equipment through the opening. The upper negative pressure dust collection pipe 1 is connected to the negative pressure air duct of the dust collection equipment. After the upstream dust collection equipment is started, a large amount of dust-laden gas will carry a small amount of light material into the interior of the dust collection hood 3. The vent holes 10 on the polyurethane woven mesh belt 7 can filter out larger materials and clumps of flocculent matter. The gas containing fine dust enters the negative pressure dust collection pipe 1 and then enters the downstream dust collection equipment for processing.

[0031] During the operation of the device, a small amount of material adheres to the polyurethane woven mesh belt 7. The rotating drum 6 is driven by the motor 9 to rotate, thereby starting the polyurethane woven mesh belt 7 to run. The scraper baffle 8 scrapes off the material adhering to the polyurethane woven mesh belt 7, thereby preventing the material from clogging the air vents 10 of the polyurethane woven mesh belt 7 and affecting subsequent dust collection.

[0032] The device is installed at the front end of the dust collection equipment, which effectively avoids the problem of large pieces of material clogging the equipment and causing the bags to stick.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
