Description

Technical Field

[0001] The utility model relates to the technical field of roller remanufacturing, in particular to a lightweight insulating dust removal cover for submerged arc welding equipment. Background Art

[0002] As an essential environmental protection measure in the industrial sector, flue gas dust removal plays a vital role in protecting the environment. The fume generated during submerged arc welding is harmful to both the environment and human health, so it must be filtered and removed using a fume dust removal device. Traditional fume dust removal devices are stand-alone, consisting of a dust collector body, a dust collection pipe, and a dust hood. These devices present the following problems: Each submerged arc welding station has at least 4-8 welding machines operating simultaneously, and each requires a dust collection device. This requires too many dust collectors, which are large and difficult to place. Since the ambient temperature of submerged arc welding exceeds 200°C, the dust collection pipe is prone to damage, making traditional dust removal equipment unable to meet the needs of multi-head submerged arc welding. By introducing a high-power, negative-pressure dust removal pipeline in the workshop, dust removal requirements can be met by routing a high-temperature-resistant dust collection pipe and dust collection hood above the submerged arc welding machine. However, existing dust collection hoods on the market are trumpet-shaped, made of iron plate and ceramic, and both types of dust collection hoods are rigid structures. Both types of dust collection hoods present the following problems:

[0003] 1. Iron plate dust hood: Due to the operating characteristics of submerged arc welding equipment, current is generated. The iron plate dust hood fixed to the welding joint requires additional insulation. Improper insulation can easily cause the dust hood to connect to electricity, causing damage to the dust hood and, in severe cases, affecting welding quality. The rigid structure of the dust hood affects the minimum spacing between welding heads, making it impossible to use multiple welding heads for some products, affecting production efficiency.

[0004] 2. Ceramic dust hood: The rigid structure of the dust hood affects the minimum spacing between welding heads, which will make some products unable to use multi-head welding, affecting production efficiency; the ceramic dust hood is difficult to fix, and if it accidentally slips, it is very easy to cause damage. The cost of the ceramic dust hood is three times that of the iron dust hood. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a lightweight insulating dust removal cover for submerged arc welding equipment, which can realize the lightweight, simple installation and insulation of the dust removal cover.

[0009] A further improvement of the technical solution of the present invention is that an insulating fixed support plate is provided inside the cover.

[0010] A further improvement of the technical solution of the present utility model is that the diameter of the dust removal hood is 170 mm and the thickness is 0.5-0.9 mm.

[0011] A further improvement of the technical solution of the present utility model is that the lower edge of the dust collecting hood is 225 mm away from the welding point at the bottom of the blanking tee.

[0012] A further improvement of the technical solution of the present utility model is that: the fixed connecting rod includes a cylinder and a circle of bases arranged at the bottom of the cylinder, and the base corresponds to the inclined shape of the cover at the fixing hole of the conductive rod; the outer diameter of the fixed connecting rod is larger than the aperture of the pole fixing hole, and the inner diameter of the fixed connecting rod is larger than the outer diameter of the conductive rod.

[0013] A further improvement of the technical solution of the present utility model is that the dust removal negative pressure connecting pipe includes a cylinder and a circle of fixing seats arranged at the bottom of the cylinder, and the fixing seats correspond to the inclined shape of the dust removal cover body at the dust removal negative pressure pipe hole.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is:

[0023] like Figure 1 As shown, a lightweight insulating dust removal cover for submerged arc welding equipment includes a fan-shaped cover body, a fixed connecting rod 2-1 and a dust removal negative pressure connecting pipe 2-2;

[0024] like Figure 2 As shown, the cover is provided with a dust removal negative pressure pipe hole 2-3, and the center position of the cover is provided with a pole fixing hole 2-4; a fixed support plate is provided inside the cover; and the fixed support plate is insulated;

[0025] like Figure 3 As shown, the fixed connecting rod 2-1 includes a cylinder and a circle base arranged at the bottom of the cylinder, and the base corresponds to the inclined shape of the cover at the conductive rod fixing hole 2-4; the outer diameter of the fixed connecting rod 2-1 is larger than the hole diameter of the pole fixing hole 2-4, and the inner diameter of the fixed connecting rod 2-1 is larger than the outer diameter of the conductive rod 1;

[0026] like Figure 4 As shown, the dust removal negative pressure connecting pipe 2-2 includes a cylinder and a circle of fixing seats arranged at the bottom of the cylinder, and the fixing seats correspond to the inclined shape of the dust removal hood body at the dust removal negative pressure pipe hole 2-3; the dust removal negative pressure connecting pipe 2-2 is inserted into the dust removal negative pressure pipe hole 2-3 from bottom to top, and is fixed on the dust removal hood 2 body through the fixing seat.

[0027] The dust hood 2 has a diameter of 170 mm and a thickness of 0.5-0.9 mm. The dust hood 2 is fixed to the conductive pole 1 by inserting a fixing connecting rod 2-1 into the pole fixing hole 2-4. The lower edge of the hood is 225 mm away from the welding point at the bottom of the blanking tee 3.

[0028] Example

[0029] 1. Select a thin and insulating material as the material of the dust cover 2. Through research and analysis of various materials on the market, it is determined that a red steel cardboard material meets the characteristics of high temperature resistance, insulation, and good flexibility. The thickness of 0.5-0.9mm can meet the use requirements.

[0030] 2. By mapping the welding head position, it was determined that the closer the dust hood is to the welding position, the smaller the size of the dust hood can be, resulting in better dust removal. While maintaining a constant suction force and ensuring complete dust absorption, the dust hood diameter was determined for different positions. Ultimately, a dust hood diameter of φ170mm, 225mm from the welding position, was chosen as the most suitable. This moderate diameter does not affect submerged arc welding operations. Red steel cardboard is highly resilient and insulated, so it has no impact on the minimum welding distance between the welding heads and the functional characteristics of the welding head itself.

[0031]

[0032] 3. The dust hood is cut out by tracing on the red steel cardboard according to the flat unfolded drawing, and then a conductive rod is curled to fix the connecting pipe and a dust removal negative pressure connecting pipe, and the dust hood is completed by connecting them together. The schematic diagram is as follows:

[0033] Different structures can be fixed directly by rivets to complete the shaping. In order to avoid internal deformation, the interior is supported by aluminum strips and fixed with rivets. All items are non-conductive and there will be no electrical connection problems.

[0034] The main function of the fixed connecting rod 2-1 is to hook the cover body and be fixed on the conductive rod 1 through a clamp, thereby fixing the entire dust removal cover 2.

[0035] The main function of the dust removal negative pressure connecting pipe 2-2 is to connect the hood and the dust removal pipeline, and to suck the smoke and dust into the main pipeline of the dust removal equipment through the negative pressure effect.
