As shown in fig. 1-3, embodiments of the present application provide a disassembly assembly 100 for disassembling a circulation pump. The circulation pump includes an impeller 210 and a coupling 220, as shown in fig. 4, the coupling 220 has a transmission shaft connected to the axial center of the impeller 210, and the rotation of the transmission shaft drives the impeller 210 to rotate.

It will be appreciated that the through-hole thread structure between the impeller 210 and the coupling 220 of most circulation pumps achieves a tight connection. In the existing maintenance method of the circulating pump, one person is required to fix the impeller 210 to prevent the impeller 210 from rotating, and the other person rotates the coupler 220, so that the threaded connection between the impeller 210 and the coupler 220 is loosened. Because impeller 210 weight is higher, the connection compactness of screwed connection department is high, and the dismantlement degree of difficulty is big, and maintenance work is wasted time and energy.

The disassembly assembly 100 provided herein may eliminate the need for manual attachment of the impeller 210. The disassembling assembly 100 comprises a first disassembling tool 110 and a second disassembling tool 120, wherein the first disassembling tool 110 is connected to the impeller 210 for fixing the impeller 210; the second disassembling tool 120 is connected to the coupling 220, and is used for loosening the joint between the coupling 220 and the impeller 210, thereby achieving the purpose of disassembling the circulation pump.

Specifically, the first disassembling tool 110 includes a fixing member 112 and a limiting member 111, the fixing member 112 is connected with the limiting member 111, and the fixing member 112 is detachably connected with the impeller 210.

As shown in fig. 6, the fixing member 112 includes a second fixing portion 1122, the second fixing portion 1122 has a rod shape, and connecting holes 11221 are formed at opposite ends of the second fixing portion 1122. In the present embodiment, the connection hole 11221 is a screw hole, which is aligned with a screw hole on the impeller 210, and the second fixing portion 1122 and the impeller 210 are fastened and fixed by screws. In other embodiments, the connection hole 11221 may be a smooth hole, and the impeller 210 and the first fixing portion 1121 are fixedly connected through a pin.

In the present embodiment, the number of the second fixing portions 1122 is one, and in other embodiments, the shape and the number of the second fixing portions 1122 may be changed accordingly. For example, when the diameter of the impeller 210 is larger and the weight of the impeller 210 is larger, a single second fixing portion 1122 is insufficient to limit the rotation of the impeller 210, two, three or more first fixing portions 1121 may be provided, and at this time, the second fixing portion 1122 has a cross shape, a rice shape or the like, so as to increase the connection strength between the second fixing portion 1122 and the impeller 210.

As shown in fig. 3 to 5, when the fixing member 112 is fixedly connected to the impeller 210, the limiting member 111 is inserted into a gap between two adjacent blades 211 of the impeller 210, and the limiting member 111 is used to limit the rotation of the impeller 210.

Specifically, the fixing member 112 further includes a first fixing portion 1121, and the number of the limiting members 111 is at least three, and at least three limiting members 111 are disposed at intervals along the circumferential direction of the first fixing portion 1121.

As shown in fig. 6, the first fixing portion 1121 is annular, the circumferential edge of the first fixing portion 1121 is circular, and the stopper 111 is circumferentially disposed on the first fixing portion 1121, and the central axis position of the stopper 111 coincides with the axial position of the impeller 210.

As an example, in the present embodiment, the number of the stoppers 111 is three, and the three stoppers 111 are circumferentially arranged and welded to the first fixing portion 1121, and the central axis position of the stoppers 111 coincides with the axis position of the impeller 210. In other embodiments, the number of the limiting members 111 may be determined according to the number of the blades 211 to use the number of the limiting members 111.

Further, in order to increase the practicality of the first dismounting tool 110, a plurality of mounting holes 11211 provided with threads are provided on the first fixing portion 1121, and the mounting holes 11211 are detachably connected to the stopper 111.

As shown in fig. 7, the first fixing portion 1121 is provided with two mounting holes 11211, and the inner mounting holes 11211 are suitable for the case where the impeller 210 is small in volume, and the outer mounting holes 11211 are suitable for the case where the impeller 210 is large in volume. When the first dismounting tool 110 is specifically used, the number and the positions of the limiting pieces 111 can be adjusted according to the size of the gap between the adjacent blades 211 of the impeller 210 and the size of the blades 211, so that the flexibility and the practicability of the first dismounting tool 110 are obviously improved.

The first fixing portion 1121 is connected to the second fixing portion 1122. Further, the first fixing portion 1121 is located between the two connection holes 11221.

The limiting members 111 are columnar, and the cross section of each limiting member 111 is one of a circle, a triangle, a rectangle, a pentagon and a hexagon. Preferably, the contact mode of the limiting piece 111 and the blade 211 is a surface contact mode, not a point contact mode, so that the limiting piece 111 is prevented from being damaged due to excessive pressure at the joint of the limiting piece 111 and the blade 211, and the service life of the first dismounting tool 110 is prolonged.

It can be understood that the limiting member 111 is provided with a groove (not shown), the groove is movably connected with the blade 211 of the impeller 210, and when the groove is connected with the impeller 210, the edge of the impeller 210 is engaged with the sidewall of the groove, which also increases the contact area between the blade 211 and the limiting member 111.

In the present embodiment, the second disassembling tool 120 is detachably connected to the coupling 220, and when the fixing member 112 is fixedly connected to the impeller 210, the second disassembling tool 120 is connected to the coupling 220, so that the second disassembling tool 120 drives the impeller 210 to rotate.

Specifically, as shown in fig. 6, the second disassembling tool 120 includes a first connecting member 121 and a second connecting member 122, the first connecting member 121 is connected to the second connecting member 122, and the first connecting member 121 is detachably connected to the coupling 220.

In this embodiment, the first connecting member 121 includes at least two connectors 1211 and a connecting rod 1212, and the at least two connectors 1211 are disposed on the connecting rod 1212 at intervals.

The connector is inserted into a pin hole of the coupler 220, thereby achieving detachable connection. The connector 1211 may be understood as a pin that mates with the coupler 220.

The connector 1211 is welded on the connecting rod 1212, and the connecting rod 1212 and the second connecting member 122 are integrally formed, so that the stability of the second disassembling tool 120 is improved, and the second disassembling tool is not easy to break.

When the fixing member 112 is fixedly connected with the impeller 210, the connector is inserted into the pin hole of the coupling 220, and the second connecting member 122 is manually rotated, so that the second connecting member 122 rotates to drive the impeller 210 to rotate.

As a preferred technical solution, in order to reduce the friction between the hands of the maintainer and the second disassembling tool 120, and improve the comfort of hand holding, it is advantageous to disassemble the coupling 220 and the impeller 210 more simply, and the outer surface of the connecting rod far away from the second connecting piece 122 is sleeved with an anti-slip soft sleeve 1213.

When the screw thread at the connection of the impeller 210 and the coupling 220 is loosened, in the related art, one person often tightens the impeller 210 and another person tightens the coupling 220, and both persons exert forces in opposite directions, thereby disassembling the circulation pump.

The inventor finds that the high-temperature steam is more emitted after the pump cover is disassembled due to the influence of the working environment factors of the desulfurizing tower, and maintenance personnel can operate at a short distance in the operation process and risk that the high-temperature steam is scalded.

In view of the above, the second disassembling tool 120 further includes a lifting member (not shown), the second connecting member 122 is in a rod shape, and one end of the connecting rod 1212 is connected to the second connecting member 122, so that the connecting rod 1212 and the second connecting member 122 form a long bar, which is beneficial to prying the impeller 210 and the coupling 220 apart.

Specifically, the movable end of the jack is movably connected to the end of the second connecting member 122 away from the first connecting member 121. In the present embodiment, the jack is a jack, and the connection between the impeller 210 and the coupling 220 is separated by using the lever principle. At this time, the maintenance personnel need to operate the movable end of the jacking member, so that the maintenance personnel is located at a position close to the jacking member and is far away from the joint of the impeller 210 and the coupling 220, and thus, the maintenance personnel cannot be scalded by high-temperature steam, and the safety of the disassembly process of the circulating pump is improved.

The method of use of the disassembly assembly 100 of the present application is as follows:

first, the connection hole 11221 of the second fixing portion 1122 is aligned with a screw hole on the impeller 210 of the circulation pump, and is fastened and fixed by a screw;

then, the connector 1211 of the second disassembling tool 120 is inserted into the pin hole of the coupler 220, the second connecting piece 122 is manually rotated, and the blades 211 of the impeller 210 are rotated;

the edge of the blade 211 is pressed after being contacted with the limiting piece 111, and the second connecting piece 122 only rotates along one direction in the disassembly process, so that the edge of the blade 211 and the limiting piece 111 can always keep a pressed state;

after the threads at the connection position of the impeller 210 and the coupling 220 are all loosened, a force is applied to one end of the second connecting piece 122 by using the jacking piece, the impeller 210 and the coupling 220 are separated by utilizing the lever principle, and then the fittings such as the main shaft, the impeller 210 and the like are further disassembled.

The disassembly process can be easily completed by only one person, and is high in disassembly efficiency and good in safety.

The present application further provides a disassembling device, including the disassembling assembly 100 in any of the foregoing embodiments, so that the disassembling device has all the beneficial effects of disassembling the assembly 100, which will not be described herein.
