Description

Technical Field

[0001] This utility model relates to a dust prevention device, and more particularly to a dust prevention device for furnace doors in a smelting and casting workshop, belonging to the field of dust prevention technology. Background Technology

[0002] In the casting workshop, the furnace door is one of the main areas for dust leakage. During production, the furnace door is frequently opened and closed, causing a large amount of high-temperature dust (including metal oxides, flux particles, etc.) to escape into the workshop environment. This dust not only pollutes the workshop air and reduces visibility, but may also harm the health of operators, such as causing respiratory diseases. To solve the above problems, operators install dustproof cloths on the outside of the dust collection hood. Traditional dustproof cloths have the following defects: ① Traditional dustproof cloths are made of ordinary canvas or silicone cloth, which are prone to aging and embrittlement under high-temperature environments, leading to damage and ineffective dust blocking; ② The sealing between adjacent dustproof cloths is insufficient, allowing dust to easily escape from the edges, resulting in poor dust blocking effect; ③ The installation and removal process of traditional dustproof cloths is complicated, affecting the normal operation of the furnace door and reducing production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a dustproof device for furnace doors in a melting and casting workshop, which significantly improves the workshop environment, extends equipment life, reduces production costs, is easy to disassemble and assemble, and is simple to operate.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] A dustproof device for furnace doors in a casting workshop includes a positioning plate, a dustproof cloth, and a positioning crossbar. The positioning plate is L-shaped and fixed to the edge of the dust collection hood by bolts. The bottom of the positioning plate is provided with a sliding groove, and at least three sliders are slidably connected in the sliding groove. The dustproof cloth is provided below the sliders, and adjacent dustproof cloths are pressed together by conical blocks and connecting holes. The bottom of the dustproof cloth is provided with a positioning ring, and the positioning crossbar passes through the positioning hole. The end of the positioning crossbar passes through a positioning sleeve, and a bolt is provided on the outside of the positioning sleeve. The positioning sleeve is set on the pillars on both sides of the dust collection hood.

[0006] The dustproof cloth is composed of a stainless steel metal fiber woven layer, a ceramic fiber felt layer, a flame-retardant fiberglass cloth, and a nano-silicone coated base cloth.

[0007] The dustproof cloth has an outer edge on its side, and a conical block is provided on the inner side of the outer edge. The conical block has a matching connecting hole at the edge of the adjacent dustproof cloth.

[0008] The slider and the groove are fixed together by bolts.

[0009] The positive and beneficial effects of this utility model are:

[0010] 1. The dustproof cloth of this utility model has a multi-layer composite structure, which can effectively block the leakage of high-temperature dust. At the same time, the nano-silicone coated base cloth has good surface smoothness, which can reduce the accumulation of dust on the cloth surface and further improve the dustproof effect. Meanwhile, the high-temperature resistant material can effectively block some of the temperature loss, especially when the furnace door is open. The high-temperature resistance also reduces the replacement cost and increases the service life of the equipment.

[0011] 2. The edges of adjacent dustproof cloths are fixed together by inserting conical blocks and connecting holes, which can ensure a tight connection between the dustproof cloths, reduce dust from escaping from the edges, and improve dust collection efficiency, which can reach more than 95%.

[0012] 3. The dustproof cloth of this utility model is slidably connected to the slide groove under the positioning plate by a slider, and then fixed with bolts on the outside of the slide groove, which is convenient to disassemble and assemble, easy to use and simple to operate.

[0013] 4. This utility model uses a positioning crossbar inside the positioning ring at the bottom of the dustproof cloth to fix the dustproof cloth, which can ensure that the dustproof cloth remains stable in high temperature and dusty environments and will not shift or loosen due to wind or vibration during operation, thus improving the overall dustproof effect.
