Description

Technical Field

[0001] The utility model relates to the technical field of skylight engineering, in particular to a closed skylight for a sludge storage bin. Background Art

[0002] The sludge has a moisture content of about 50% and is highly volatile. The volatile gases contain dozens of toxic bacteria, which are seriously harmful to people's health and are an important source of pollution for air control. Considering the low visibility in the sludge silo and the difficulty in seeing when operating the sludge grab, skylights are usually installed on the roof of the sludge silo to supplement the illumination in the silo. However, the odor generated by sludge fermentation can easily escape from the skylight, causing a foul odor in the surrounding area, which is difficult to control. In addition, sludge odor usually contains highly corrosive gas components, so the introduction of closed and corrosion-resistant skylights is the primary link for sludge treatment plants to do a good job in environmental protection.

[0003] Conventional skylights generally only consider the lighting function, cannot prevent odor from escaping, and have poor corrosion resistance. Therefore, developing a closed skylight for sludge storage silos is a technical problem that needs to be solved urgently. Utility Model Content

[0031] Example

[0032] See also Figures 1 to 5 This embodiment provides a sludge storage bin sealed skylight, including:

[0033] The U-shaped groove fixing member 2 is fixed on the roof wall 1 with a reverse buckle, and is leveled and sealed with a sealant and a rubber strip 21;

[0034] The inner and outer sides of the bottom edge of the skylight base 3 are fully welded to the U-shaped groove fixing member 2, and the weld is covered with anti-corrosion paint;

[0035] The window subframe 4 is fixed on the skylight base 3, and the heat insulation strip 42 and the glass 5 are sequentially mounted thereon;

[0036] The aluminum plate 6 is fixedly connected to the upper wall 1 and the window sub-frame 4, and its upper and lower openings are sealed by foam strips 7 and sealant;

[0037] The waterproofing membrane 8 is fixedly laid from the roof to the upper edge of the edge-wrapped aluminum plate 6, and the height of covering the edge-wrapped aluminum plate 6 is not less than 100 mm.

[0038] As a specific example, the sludge silo roof is equipped with 22 skylights for lighting, and the reserved opening size of each skylight is 2400mm×1500mm. Figure 1 The skylight reserved opening is of reinforced concrete structure, with a wall thickness of 100 mm and a 500-mm upward turn from the roof.

[0039] See Figure 2 The airtight skylight is located on the top of the 1st reinforced concrete upward-turning wall. The materials and equipment required for skylight construction include: folder, cutting machine, aluminum sheet, self-tapping screw, galvanized steel U-shaped fixing part, rubber pad, foam strip, sealant, galvanized square pipe, anti-corrosion paint, medium-transmittance LOW-E glass, electric welding machine, aluminum alloy auxiliary frame, SBS waterproof coiled material, cement, construction glue, water, glue gun, heat insulation strip.

[0040] See Figures 3 to 5 The specific construction steps of the above airtight skylight are as follows:

[0041] Step 1: Fully cover the 1st reinforced concrete upward-turning wall with a 10-mm-thick rubber strip 21, paste the rubber strip on the concrete upward-turning wall 1 using silicone sealant, and seal both side joints.

[0042] Step 2: Use the 1st self-tapping screw 91 to fix the 2-mm-thick galvanized steel U-shaped groove fixing part 2 in an inverted manner on the upward-turning wall 1, press the 10-mm rubber strip 21, and wrap the upward-turning wall without leaving any gap.

[0043] Step 3: Use a cutting machine to cut the galvanized square pipe with a size of 100 mm × 100 mm × 5 mm thick, and form a "day"-shaped skylight base 3 along the wellhead. Both the inner and outer sides of the bottom edge of the skylight base are fully welded (full weld points 23) to the U-shaped groove fixing part 2, and the welding slag is knocked off and the weld seam is painted with anti-corrosion paint.

[0044] Step 4: Use the 2nd self-tapping screw 92 to fix the aluminum alloy window auxiliary frame 4 on the skylight base 3.

[0045] Step 5: Install a 24-mm-high heat insulation strip 42.

[0046] Step 6: Install the medium-transmittance LOW-E + 12Ar + 5-mm-thick glass 5.

[0047] Step 7: Install the 2.5-mm-thick edge-wrapping aluminum sheet 6, use the 3rd self-tapping screw 93 to fix the edge-wrapping aluminum sheet 6 to the upward-turning wall 1 and the window auxiliary frame, and install the foam strip 7 and apply silicone sealant at the upper and lower openings of the edge-wrapping aluminum sheet.

[0048] Step 8: Wet-lay the 3-mm-thick SBS waterproof coiled material 8. The wet-laying adhesive material is a mixture of cement, construction glue and a certain proportion of water. The wet-laying area is from the roof to the upper opening of the edge-wrapping aluminum sheet 6, and the height covering the edge-wrapping aluminum sheet is not less than 100 mm. Press the SBS coiled material on the edge-wrapping aluminum sheet with self-tapping screws.

[0049] The present embodiment is a preventive measure taken to address the air pollution caused by the odor escaping from the unsealed skylight of the sludge silo and the light pollution caused by the skylight's strong light transmittance and glare. In view of the high moisture content, high volatility and high corrosion characteristics of the sludge, a rubber pad and a sealant are used to level the concrete upper opening and the U-shaped groove fixing piece to form a first seal; a U-shaped groove fixing piece is welded to the galvanized square steel window base in a full circle to form a second seal; a window sub-frame and a middle transparent glass are crimped to form a third seal; an aluminum plate and a sealant are used to form a fourth seal on the outer edge of the window frame; and an SBS waterproof membrane is turned up on the upper side of the aluminum plate to wrap the upper opening of the skylight as a whole to form a fifth seal. This embodiment further uses corrosion-resistant materials (rubber pads, galvanized sheet U-shaped groove fixings, galvanized square tube skylight base, LOW-E hollow glass, edging aluminum plate, silicone sealant, SBS waterproof membrane) to seal the skylight. Each process strictly implements the principles of anti-corrosion and airtightness to prevent odor from escaping, so as to play a role in curing atmospheric environmental pollution. In view of the high light transmission of the skylight window, which has a light pollution effect on the sludge crane operation, LOW-E glass with a visible light transmittance of 0.6 is used to prevent light pollution. The installed glass is slightly lower than the edging aluminum plate.

[0050] In summary, the utility model provides a sludge storage silo sealed skylight, including: a U-shaped groove fixing piece, which is fixed on the roof wall with reverse buckle, and is leveled and sealed with sealant and rubber strips; a skylight base, both inner and outer sides of the bottom edge are fully welded to the U-shaped groove fixing piece, and the weld is covered with anti-corrosion paint; a window sub-frame, which is fixed to the skylight base, and a heat insulation strip and glass are installed thereon in sequence; an edged aluminum plate, which is fixedly connected to the upper wall and the window sub-frame, and its upper and lower openings are sealed with foam strips and sealant; a waterproof coiled material, which is fixedly laid from the roof to the upper end of the edged aluminum plate, and the height of the edged aluminum plate is not less than 100 mm. The utility model uses a corrosion-resistant multiple sealing structure to prevent odor from escaping through the skylight.
