Description

TECHNICAL FIELD

[0001] The utility model relates to a coal powder system technical field, especially a kind of powder collecting box baffle for coal powder bin. BACKGROUND

[0002] Powder collecting box is the main coal powder collecting device of coal powder bin.Powder pipeline is directly connected with powder collecting box, and the baffle of powder collecting box is suspendedly installed on the opposite side of powder pipeline.In use, the baffle is easily detached under the scouring of gas-powder mixture, which causes the problem of high furnace stop spraying due to the blockage of discharge port.

[0003] In addition, coal powder is contained in the powder bin, and it is impossible to directly carry out fire operation to weld the suspension support of baffle, which brings great difficulty to maintenance work. CONTENT OF UTILITY MODEL

[0004] In view of the above technical problems, the utility model provides a kind of powder collecting box baffle for coal powder bin, to solve the problem that the baffle of traditional powder collecting box is easily detached under the scouring of gas-powder mixture.

[0005] In order to realize the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0006] A kind of powder collecting box baffle for coal powder bin, including powder collecting box top cover, further including cover plate and baffle, baffle is vertically inserted on cover plate, after the bottom of baffle passes through powder collecting box top cover, cover plate is connected with powder collecting box top cover by fastener.

[0007] The top surface of cover plate is provided with a plurality of rib plates on the two sides of baffle, and the two sides of baffle are detachably connected with rib plates.

[0008] Two support blocks are oppositely installed on the inner side of the lower part of baffle.

[0009] Abrasion-resistant layer is arranged on the two side surfaces of baffle.

[0010] Baffle and support block are detachably connected.

[0011] Compared with prior art, the utility model has the advantages that: the utility model is simple in structure, baffle is stably installed on powder collecting box by the mode that cover plate is connected with powder collecting box top cover by fastener, which avoids that baffle directly enters coal powder bin, eliminates the hidden danger that baffle is detached and blocked in coal powder bin due to the scouring of gas-powder mixture, and is convenient to operate, less investment, quick effect.Meanwhile, the setting of rib plate enhances the strength of baffle, the setting of abrasion-resistant layer prolongs the service life of baffle, and the detachable connection of support block facilitates maintenance and replacement.Daily maintenance does not need fire operation, which greatly reduces the labor intensity of maintenance personnel and effectively reduces the probability of equipment failure. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 The utility model discloses a structure schematic diagram.

[0013] In the drawing:

[0014] 1, powder collecting box top cover, 2, cover plate, 3, web, 4, fastener, 5, material baffle, 6, support block. DETAILED DESCRIPTION

[0015] In order to make the purpose, technical scheme and advantage of the utility model more clear and explicit, below combining with specific embodiment and referring to attached drawing, the utility model is further detailedly explained.Should understand, these descriptions are only exemplary, and not to limit the scope of the utility model.In addition, in following explanation, the description of known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0016] A kind of powder collecting box material baffle for coal powder bin, including powder collecting box top cover 1, still including cover plate 2 and material baffle 5, material baffle 5 is vertically inserted on cover plate 2, after material baffle 5 bottom passes through powder collecting box top cover 1, cover plate 2 is connected with powder collecting box top cover 1 by fastener 4, to form a closed space, prevent coal powder from leaking out with material baffle 5 stably installed on powder collecting box.

[0017] The top surface of cover plate 2 material baffle 5 both sides are equipped with several web 3, web 3 is detachably connected with the both sides of material baffle 5, both facilitates installation and disassembly, and can enhance the structural strength of material baffle 5, so that it can better withstand the scouring of gas powder mixture.

[0018] The inner side lower part of material baffle 5 is relatively equipped with two support blocks 6, and the support block 6 provides additional support for the material baffle 5, improves the stability of the material baffle 5 during use.

[0019] Abrasion-resistant layer is arranged on the both sides of material baffle 5, and the abrasion-resistant layer can be fixed on the material baffle 5 by welding or the like, which can effectively reduce the abrasion of the gas powder mixture on the material baffle 5 and prolong the service life.

[0020] Material baffle 5 and support block 6 are detachably connected.

[0021] When using:

[0022] The utility model discloses when installing, first vertical spigot joint in apron 5 on apron 2, then the bottom of apron 5 passes through the powder collecting box top cover 1, then through fixed bolt nut washer apron 2 and powder collecting box top cover 1 are fastened and are connected through fastener 4. In the use, when the gas powder mixture impacts apron 5, the rib plate 3 strengthens the strength of apron 5, and the supporting block 6 provides additional support, and the wear -resisting layer reduces the abrasion. When needing maintenance or replacing parts, only need to disassemble corresponding fastener 4, can replace or repair rib plate 3, supporting block 6 etc., and the operation is convenient and fast, need not fire operation, reduces the labor intensity and maintenance cost.
