Description

Novel powder concentrator barrel upper cover

Technical Field

The utility model relates to a novel powder concentrator barrel upper cover belongs to powder concentrator technical field.

Background

At present, a flange is welded on a cylinder body 1 of the existing powder concentrator (as shown in figure 1), after a cylinder cover 3 and a shell 4 are assembled together, the whole body is connected with the flange on the cylinder body 1, a rubber strip 2 plays a role in sealing in the middle, and thus the cylinder body 1 meets the sealing requirement. Then, in the machining process, the requirement on the machining precision of the connection part of the cylinder cover 3 and the shell 4 is high, but the deformation of the cylinder cover 3 is difficult to control in the blanking process, and particularly after the rib plates are welded, a large machining allowance is formed; in the later use process, the rubber strip 2 is aged, and the rubber strip 2 can be pumped into the cavity in the cylinder 1 under the condition of overlarge wind power, so that the powder selecting effect is influenced, and the yield is reduced; the maintenance is troublesome, and the bolts connected with the whole barrel cover 3 can be maintained only by being disassembled, so that the design of the novel powder concentrator barrel upper cover is necessary for solving the problems.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the technical problem that above-mentioned background art mentioned, and adopt following technical scheme to realize:

the utility model provides a novel powder concentrator barrel upper cover, includes barrel, cover and casing, still includes strengthening rib, cover flange and asbestos rope, the upper end and the cover of barrel weld mutually, the strengthening rib is installed in the junction between the cover and the barrel the two for play the increase intensity effect between to cover and the barrel, the bottom of casing is fixed on the cover flange through a bolt, the cover flange passes through two number bolt fastening on the cover, just the inside of barrel is stretched into to the bottom of casing, the asbestos rope is established between the cover flange and the cover the two, is used for playing sealed effect between cover flange and the cover.

As a preferred example, the number of the bolts of number one is multiple, and a plurality of the bolts of number one are annularly and equally spaced on the housing, the number of the bolts of number two is also multiple, and a plurality of the bolts of number two are annularly and equally spaced on the housing, and the number of the bolts of number one is different from the number of the bolts of number two.

As a preferred example, the type of the bolt A and the type of the bolt B are both M16.

The utility model has the advantages that: the processing difficulty of the device is reduced, the barrel cover on the barrel body does not need to be processed, only drilling and tapping are needed, and the inner hole of the barrel body can be put down to form an assembled whole; the structure is compact, the maintenance is more convenient, and only the bolt on the cylinder cover flange needs to be removed; structural stability is better, and the barrel is in the same place with the cover welding, and is more durable firm, and the bearing capacity is bigger, and stability is better.

Detailed Description

In order to understand the technical means, creation features, achievement purposes and functions of the present invention easily, the present invention will be further explained by combining with the specific drawings.

As shown in figures 1-8, the novel upper cover of the powder concentrator barrel comprises a barrel body 1, a barrel cover 3 and a shell 4, and further comprises a reinforcing rib 5, a barrel cover flange 6 and an asbestos rope 7, wherein the upper end of the barrel body 1 is welded with the barrel cover 3, the reinforcing rib 5 is installed at the joint between the barrel cover 3 and the barrel body 1 and used for increasing the strength between the barrel cover 3 and the barrel body 1, the bottom of the shell 4 is fixed on the barrel cover flange 6 through a No. one bolt, the barrel cover flange 6 is fixed on the barrel cover 3 through a No. two bolt, the bottom of the shell 4 extends into the barrel body 1, and the asbestos rope 7 is arranged between the barrel cover flange 6 and the barrel cover 3 and used for sealing between the barrel cover flange 6 and the barrel cover 3.

The number of the bolts A is multiple, the bolts A are annularly and equidistantly distributed on the shell 4, the bolts B are multiple, the bolts B are annularly and equidistantly distributed on the shell 4, and the bolts A are different from the bolts B in number.

The type of the bolt A and the type of the bolt B are both M16.

The working principle is as follows: directly welding the upper part of the cylinder body 1 with the cylinder cover 3, and fixing the cylinder body with a reinforcing rib plate 5; the cylinder cover flange 2 is connected with the shell 4 by bolts (preferably 4M 16 bolts), the assembled whole body and the cylinder body 1 are fixed on the cylinder cover 3 on the cylinder body 1 by bolts (16M 16 bolts are used), and the whole body and the cylinder cover 3 are sealed by asbestos ropes 7.

The foregoing shows and describes the basic principles and principal features of the invention, together with the advantages thereof. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the present invention, and all such changes and modifications fall within the scope of the present invention as claimed.
