Description

Technical Field

[0001] The utility model relates to the technical field of powder classifiers, in particular to a flange connection device for a powder classifier. Background Art

[0002] At present, the common small powder classifiers are mainly composed of three parts: the upper shell, the middle shell and the lower shell. The connection between each part is connected by flange bolts. If the error between the bolt holes of the flange is large, it cannot be assembled. In production, the bolt holes can be cut together when the flange is cut, and then the flange with the cut bolt holes is welded to the corresponding shell. This manufacturing method of cutting the bolt holes of the flange first and then welding will cause deviations in the bolt hole spacing due to welding deformation. In production, the bolt holes can also be drilled on the flange after the flange and the shell are formed and welded. This manufacturing method of drilling bolt holes on the flange after welding, in the process of mass production, the use of templates for drilling holes will also cause errors due to long-term use of the template and errors in the drilling process, resulting in the upper flange bolt holes and the lower flange bolt holes not corresponding to each other during installation, and the bolts cannot be installed. At the same time, large-scale drilling also requires a lot of man-hours.

[0003] In summary, it is necessary to invent a new powder classifier flange connection device to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a powder classifier flange connection device in view of the deficiencies of the above-mentioned prior art. The powder classifier flange connection device fixes a circle of upper round blocks at the end of the upper flange, fixes a circle of lower round blocks at the end of the lower flange, and then fixes the upper and lower round blocks by clips, thereby avoiding the problem that the upper flange and the lower flange cannot be installed due to errors in the bolt hole distance in the traditional way of connecting the upper flange and the lower flange. Moreover, the subsequent on-site installation of the powder classifier flange connection device can arbitrarily adjust the orientation of the upper flange and the lower flange according to the on-site process layout, thereby adjusting the orientation between the upper shell of the powder classifier and the lower shell of the powder classifier.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is:

[0006] A powder classifier flange connection device comprises a circle of upper round blocks, a circle of lower round blocks and clips, wherein the circle of upper round blocks is fixedly connected to the upper surface edge of the upper flange at the bottom of the upper shell of the powder classifier, and the circle of lower round blocks is fixedly connected to the lower surface edge of the lower flange at the top of the lower shell of the powder classifier. The upper round blocks and the lower round blocks are connected to each other by the clips to realize the connection between the upper flange and the lower flange.

[0007] As a further improved technical solution of the utility model, the upper round block and the lower round block are made of round steel.

[0008] As a further improved technical solution of the utility model, a circle of upper round blocks is connected to the upper surface edge of the upper flange at the bottom of the upper shell of the powder classifier by welding, and a circle of lower round blocks is connected to the lower surface edge of the lower flange at the top of the lower shell of the powder classifier by welding.

[0009] As a further improved technical solution of the utility model, the clamp includes an upper clamping block, a lower clamping block and a connecting pair, the upper clamping block clamps the upper round block, the lower clamping block clamps the lower round block, and the upper clamping block and the lower clamping block are connected by the connecting pair.

[0010] As a further improved technical solution of the utility model, an upper hook for clamping the upper round block is provided on the top of the upper clamping block, and an upper through hole is opened on the upper clamping block;

[0011] The bottom of the lower clamping block is provided with a lower clamping hook for clamping the lower round block, a cavity with a top opening is provided in the lower clamping block, and the bottom of the lower clamping block is provided with a lower through hole connected to the cavity;

[0012] After the bottom of the upper card block is inserted into the cavity in the lower card block, the upper through hole of the upper card block is connected with the lower through hole of the lower card block through the cavity in the lower card block, and the upper through hole of the upper card block is connected with the lower through hole of the lower card block through a connecting pair.

[0013] As a further improved technical solution of the utility model, the connection pair is a bolt pair.

[0014] As a further improved technical solution of the utility model, the upper round block and the lower round block are connected to each other through a plurality of clips.

[0015] The beneficial effects of the utility model are:

[0016] The flange connection device of this embodiment welds a circle of round steel at the end of the upper flange, welds a circle of round steel at the end of the lower flange, and then fixes the two round steels by multiple clips. When the clips are fixed, the upper hook of the upper clamping block clamps the upper round steel, and the lower hook of the lower clamping block clamps the lower round steel. After the bottom of the upper clamping block is inserted into the cavity in the lower clamping block, the upper through hole of the upper clamping block is connected to the lower through hole of the lower clamping block through the cavity in the lower clamping block, and the upper through hole of the upper clamping block and the lower through hole of the lower clamping block are connected by a connecting pair to achieve the fixation between the two round steels, and then achieve the connection between the upper flange and the lower flange. In this way, it is avoided that the bolt hole spacing has an error and the installation cannot be installed, and this flange connection method allows the subsequent on-site installation to arbitrarily adjust the orientation of the upper shell and the lower shell according to the on-site process layout.

[0024] The specific implementation of the utility model is further described below according to the accompanying drawings:

[0025] Figure 1-2 The present invention is a schematic diagram of the flange connection structure of an existing small powder selector, wherein the flange bolt holes on the upper flange 3 welded at the bottom of the upper shell 1 of the powder selector and the flange bolt holes on the lower flange 4 welded at the top of the lower shell 2 are connected by bolts 5 to achieve a fixed connection between the upper shell 1 and the lower shell 2. If the error between the flange bolt holes on the upper flange 3 and the flange bolt holes on the lower flange 4 is large, the assembly cannot be performed. Based on the above problems, this embodiment provides a novel flange connection device for a powder selector.

[0026] like Figure 3-4 As shown, a flange connection device for a powder classifier comprises a circle of upper round blocks 6, a circle of lower round blocks 7 and clips, wherein a circle of upper round blocks 6 is fixedly connected to the upper surface edge of an upper flange 3 welded at the bottom of an upper shell 1 of the powder classifier, and a circle of lower round blocks 7 is fixedly connected to the lower surface edge of a lower flange 4 welded at the top of a lower shell 2 of the powder classifier, and the upper round blocks 6 and the lower round blocks 7 are connected to each other by clips to achieve connection between the upper flange 3 and the lower flange 4.

[0027] In this embodiment, the upper round block 6 and the lower round block 7 are made of round steel.

[0028] In this embodiment, a circle of upper round blocks 6 is connected to the upper surface edge of the upper flange 3 welded at the bottom of the upper shell 1 of the powder classifier by welding, and a circle of lower round blocks 7 is connected to the lower surface edge of the lower flange 4 welded at the top of the lower shell 2 of the powder classifier by welding.

[0029] In this embodiment, Figure 5As shown, the clamp includes an upper clamping block 8, a lower clamping block 9 and a connecting pair 10. The upper clamping block 8 clamps the upper round block 6, and the lower clamping block 9 clamps the lower round block 7. The upper clamping block 8 and the lower clamping block 9 are connected by a connecting device.

[0030] In this embodiment, Figure 6-7 As shown, the top of the upper clamping block 8 is provided with an upper hook 801 for clamping the upper round block 6, and the upper clamping block 8 is provided with an upper through hole 802; the bottom of the lower clamping block 9 is provided with a lower hook 901 for clamping the lower round block 7, and a cavity 902 with a top opening is provided in the lower clamping block 9, and the bottom of the lower clamping block 9 is provided with a lower through hole 903 connected to the cavity 902.

[0031] After the bottom of the upper card block 8 is inserted into the cavity 902 in the lower card block 9, the upper through hole 802 of the upper card block 8 is connected with the lower through hole 903 of the lower card block 9 through the cavity 902 in the lower card block 9, and the upper through hole 802 of the upper card block 8 is connected with the lower through hole 903 of the lower card block 9 through the connecting pair 10.

[0032] In this embodiment, the connection pair 10 is a bolt pair.

[0033] In this embodiment, the upper round block 6 and the lower round block 7 are connected to each other through a plurality of clips.

[0034] In the flange connection device of this embodiment, a circle of round steel is welded at the end of the upper flange 3, and a circle of round steel is welded at the end of the lower flange 4, and then the two round steels are fixed by multiple clips. When the clips are fixed, the upper hook 801 of the upper clamping block 8 clamps the upper round steel, and the lower hook 901 of the lower clamping block 9 clamps the lower round steel. After the bottom of the upper clamping block 8 is inserted into the cavity 902 in the lower clamping block 9, the upper through hole 802 of the upper clamping block 8 is connected with the lower through hole 903 of the lower clamping block 9 through the cavity 902 in the lower clamping block 9, and the upper through hole 802 of the upper clamping block 8 and the lower through hole 903 of the lower clamping block 9 are connected by the connecting pair 10 to achieve the fixation between the two round steels, and then achieve the connection between the upper flange 3 and the lower flange 4. In this way, it is avoided that the installation cannot be carried out due to the error of the bolt hole distance, and the subsequent on-site installation can arbitrarily adjust the orientation of the upper shell 1 and the lower shell 2 according to the on-site process layout.
