The conical section 6 is further connected with a hollow cylindrical section 7 below; the cyclone section, the conical section and the cylindrical section are coaxial;

[0025] The cyclone section 5 is in the shape of a cylinder. A cover plate 14 is connected to the top surface of the cyclone section 5. The cover plate has an opening in which an exhaust pipe 9 is inserted. The exhaust pipe is coaxial with the cyclone section. A rectangular air inlet is formed in the side surface of the upper part of the cyclone section. An air inlet pipe 8 is connected to the air inlet. The outer side plate of the air inlet pipe is tangent to the side wall of the cyclone section.

[0026] The cylindrical section 7 constitutes the base of the cyclone dust collector. A foundation embedded part is connected below the cylindrical section. The hollow cylindrical section also serves as the ash hopper of the cyclone dust collector. An openable and closable ash removal port is formed in the side surface of the cylindrical section.

[0027] The cyclone section, the conical section, the cylindrical section, the cover plate, the air inlet pipe and the exhaust pipe are all made of galvanized steel plate.

[0028] The cyclone section, the conical section, the cylindrical section and their mutual connections are all of assembled structure. The cyclone section, the conical section and the cylindrical section are each composed of a plurality of single plates 15.

[0031] The main body of the cover plate 14 is in the shape of a circular ring. A protruding part serving as the top plate of the air inlet pipe is connected to the side of the main body. The outer edge of the main body of the cover plate has a downward bent edge with bolt holes formed therein. In this example, the exhaust pipe 9 is first connected with a square plate. Then, the exhaust pipe is inserted into the hollow of the cover plate 14. The square plate is connected with the cover plate through a bolt structure.

[0032] Further reference Figure 3 The single plate 15 constituting the cyclone section is a rectangular single plate.

[0033] The two side edges of the rectangular single plate have bent edges 16 with bolt holes formed therein. The bolt holes in the corresponding bent edges of two adjacent rectangular single plates are threaded with connecting bolts (i.e. connected through bolts and can be disassembled).

[0034] The bottom edge of the rectangular single plate has a bent edge 16 with a bolt hole formed therein for connecting with the conical section.

[0035] The upper part of the rectangular single plate has a bolt hole corresponding to the bolt hole in the bent edge of the main body of the cover plate. The bolt holes are threaded with connecting bolts.

[0036] The two side plates and the bottom plate of the air inlet pipe 8 are connected by bolt holes and connecting bolts.

[0037] There can also be a sealing structure between the bottom surface of the sealing plate 15 and the top edge of the cyclone section 5, such as a sealing ring or sealing glue.

[0038] The top plate of the air inlet pipe is an integral structure with the sealing plate, while the other three plates of the air inlet pipe are independent plate pieces, which are connected to each other and to the side wall of the cyclone section through bolt structure. The part of the side wall that cannot be sealed by a complete rectangular single plate due to the connection of the air inlet pipe can be cut and connected to other rectangular single plates or air inlet pipe side plates through bending edges and bolt holes.

[0039] II. Conical section

[0040] Further referring to Figure 4 The single plate 15 constituting the conical section is a ladder-shaped single plate;

[0041] The long side of the ladder-shaped single plate is on the top; both sides of the ladder-shaped single plate have a bending edge 16 with a bolt hole; the bolt holes in the corresponding bending edges of two adjacent ladder-shaped single plates are connected by connecting bolts; the long side of the ladder-shaped single plate has a bending edge 16 with a bolt hole for connecting the cyclone section;

[0042] The lower part of the ladder-shaped single plate has a bolt hole for connecting the bottom flange 11.

[0043] III. Cylinder section

[0044] Further referring to Figure 3 The single plate 15 constituting the cylinder section is a rectangular single plate;

[0045] Both sides of the rectangular single plate have a bending edge 16 with a bolt hole, and the bolt holes in the corresponding bending edges of two adjacent rectangular single plates are connected by connecting bolts;

[0046] The top edge of the rectangular single plate has a bending edge 16 with a bolt hole for connecting the bottom flange 11;

[0047] The lower part of the rectangular single plate has a bolt hole for connecting the base flange 12.

[0048] IV. Connection of conical section and cylinder section

[0049] The shape of the bottom flange 11 is that a cylindrical side is connected to the inner edge of a horizontal ring; the horizontal ring has a bolt hole for connecting the cylinder section 7; the cylindrical side has a bolt hole for connecting the lower part of the conical section 6.

[0050] V. Connection of cylinder section and base flange

[0051] The shape of the base flange 12 is a horizontal circular ring with a cylindrical side connected to the inner edge; the outer edge of the horizontal circular ring is evenly distributed with multiple protrusions 10, which are used to open bolt holes for connecting the foundation embedded parts;

[0052] The cylindrical side is provided with bolt holes for connecting the lower part of the cylindrical segment 7.

[0053] As a further strengthening structure: there is a strip-shaped bend on the single plate 15, and the bend line 13 is located at the median line of the single plate. In each single plate, the bent edge of the upper and / or lower edge forms a reinforcing rib.

[0054] The design principle of the dust collector is explained.

[0055] In the traditional cyclone dust collector, the lower part is a reverse conical structure, and the assembled structure of the dust collector of the utility model considers the structural strength, and designs the conical segment into a bolted conical segment and a bolted cylindrical segment. The flange assembly of the conical segment and the cylindrical segment adopts a bolted circular flange (bottom flange 11) to strengthen, which ensures the circularity and the structural torsional strength.

[0056] The cylindrical segment part adopts a vertical bolted assembly form, and uses an outer folded reinforcing rib (bent edge at the top edge position) and a bend (bend line 13) at the center of the part to strengthen the vertical stress of the plate.

[0057] The bottom of the cylindrical segment adopts a 10-12mm thick base flange 12, which is bolted with the cylindrical segment. The base flange is finally connected with the foundation embedded part.

[0058] The advantage of the design of the cylindrical segment is that the steel structure installation rack is cancelled, and the cylindrical segment with a large cross-sectional area is directly designed as a base, which can resist wind load and bear its own weight, is stable and economical, and saves the investment of the equipment. At the same time, compared with the traditional conical structure, the cylindrical segment is more conducive to the bottom dust removal of the humid dust-containing tail gas, and the large cross-sectional area will not cause blockage.

[0059] The main body of the cyclone dust collector is made of hot-dip galvanized sheet (with a 275g / m2 galvanized layer as the best), and the full assembled structure can also avoid the defect of welding damage to the galvanized layer. During processing, the hot-dip galvanized sheet can be cut into parts by CNC laser cutting, and then formed by sheet metal bending processing. All parts are packaged into groups, transported to the site, and then assembled and formed.

[0060] The cyclone dust collector is assembled structure, and is transported in the form of spare parts package. The cyclone dust collector is assembled on the use site, and transportation cost is greatly saved. The cylindrical base simplifies the support steel structure, and will not be blocked to reduce daily maintenance. Meanwhile, the cyclone dust collector is entirely made of hot-dip galvanized sheet with a galvanized layer of 275 g / m2, which has better corrosion resistance. The cyclone dust collector is suitable for long-term use of indoor and outdoor high-humidity tail gas, and the expected open-air service life is up to 20 years.
