[0034] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] like Figures 1 to 5 As shown, this embodiment provides a disassembly tool 100 for a liquid ring pump fan impeller, comprising a mounting frame 1, an ejection assembly 2 and two connecting members 3. The mounting frame 1 is formed into an annular structure, and the mounting frame 1 includes a first mounting plate 11, a second mounting plate 12, a third mounting plate 13 and a fourth mounting plate 14 which are connected end to end in sequence, the first mounting plate 11 and the fourth mounting plate 14 are arranged opposite to each other, the first mounting plate 11 is provided with a first through hole 111, a second through hole 112 and a third through hole 113, and the second through hole 112 and the third through hole 113 are arranged on both sides of the first through hole 111; the ejection assembly 2 includes an ejection device 21 and an ejection rod 22, the ejection device 21 is used to be arranged in the mounting frame 1, the ejection rod 22 is penetrated in the first through hole 111, one end of the ejection rod 22 is abutted against the output end of the ejection device 21, and the other end of the ejection rod 22 is used to abut against the wheel shaft 202 of the liquid ring pump fan; the two connecting members 3 are respectively penetrated in the second through hole 112 and the third through hole 113, and are respectively used to be connected to the impeller 201 of the liquid ring pump fan.

[0037] In order to facilitate relevant technical personnel to have a clearer and more accurate understanding of the technical solution of the present application, the working principle / working process of the above technical solution is first explained below.

[0038] When it is necessary to disassemble the impeller 201, the two connecting members 3 can be first inserted into the second through hole 112 and the third through hole 113, and connected to the impeller 201 of the liquid ring pump fan, so that there is a connection relationship between the mounting frame 1 and the impeller 201, and then the ejection device 21 can be started, and the output end of the ejection device 21 will apply force to the wheel shaft 202 of the liquid ring pump fan through the ejection rod 22. Since the mounting frame 1 is connected to the impeller 201, and the wheel shaft 202 of the liquid ring pump fan is fixedly installed by the mounting structure, the impeller 201 connected to the mounting frame 1 will be separated from the wheel shaft 202 under the action of the ejection device 21, thereby realizing the disassembly of the impeller 201.

[0039] Through the above technical solution, on one hand, the disassembly tool of the present application can effectively make the impeller 201 relatively stably detach from the wheel shaft 202 in the horizontal direction during the disassembly of the impeller 201, thereby effectively avoiding the possible deviation of the impeller 201 during the disassembly process, thereby effectively avoiding the problem of damage to the wheel shaft 202 due to the deviation of the impeller 201. At the same time, during the disassembly process, the disassembly tool is connected to the impeller 201 through two connecting members 3, and the force transmission direction between the connecting member 3 and the impeller 201 is extended along the axial direction of the impeller 201, so during the entire disassembly process, the connecting member 3 will not cause structural damage to the impeller 201.

[0040] On the other hand, during the process of disassembling the impeller 201, the disassembly tool of the present application only needs to install the connecting piece 3, and then the impeller 201 can be disassembled through the ejection device 21, which can very conveniently realize the disassembly of the impeller 201.

[0041] In this embodiment, it should be noted that

[0042] First, the mounting frame 1 of the present application may be integrally cast, or may be welded from a first mounting plate 11, a second mounting plate 12, a third mounting plate 13 and a fourth mounting plate 14, and the present application does not make any specific limitation on this.

[0043] Second, the connection members 3 of the present application are provided in two pieces, which has two advantages. First, the connection reliability between the mounting frame 1 and the impeller 201 can be effectively ensured. At the same time, the interaction force between the mounting frame 1 and the impeller 201 is shared by the two connection members 3, which is conducive to further avoiding damage to the impeller 201. Second, the two connection members 3 can effectively ensure the spatial position of the first through hole 111 during the disassembly process of the impeller 201, thereby facilitating the stability of the relative position of the ejection rod 22 during the disassembly process of the impeller 201, and ensuring that the impeller 201 can be relatively stably separated from the wheel shaft 202 in the horizontal direction, further avoiding damage to the wheel shaft 202.

[0044] Third, the ejection rod 22 of the present application can be selected according to actual needs. For example, during the initial disassembly process, the length of the ejection rod 22 can be selected to be equal to or less than the thickness of the first mounting plate 11, so as to more reliably connect the impeller 201 and the mounting frame.

[0045] Fourth, it is understandable that as the disassembly process proceeds, the extension length of the output end of the ejection assembly 2 may reach a maximum, but the impeller 201 and the axle 202 have not yet been completely separated. At this time, a longer ejection rod 22 can be replaced to allow the impeller 201 and the axle 202 to be completely separated.

[0046] Fifth, the ejection device 21 of the present application may be a hydraulic pushing device, such as a hydraulic jack, or a pneumatic pushing device, such as a pneumatic push rod, which is not specifically limited in the present application.

[0047] In one embodiment of the present application, Figures 3 to 5 As shown, the second mounting plate 12 of the present application may be formed with a strip-shaped first weight-reducing through hole 121, and the third mounting plate 13 may also be formed with a strip-shaped second weight-reducing through hole 131. In this way, the material usage and deadweight of the mounting frame 1 can be effectively reduced, thereby effectively saving manufacturing costs and effectively facilitating the transportation and use of the disassembly tool 100 for the fan impeller of the liquid ring pump of the present application.

[0048] In one embodiment of the present application, Figures 3 to 5 As shown, the first weight-reducing through hole 121 and / or the second weight-reducing through hole 131 of the present application can be formed as a waist-shaped hole. In this way, the waist-shaped hole can reduce the local stress concentration of the second mounting plate 12 and / or the second mounting plate 12 during use, thereby effectively ensuring the structural integrity and durability of the mounting frame 1.

[0049] In one embodiment of the present application, the first mounting plate 11, the second mounting plate 12, the third mounting plate 13 and the fourth mounting plate 14 of the present application are all formed into a hollow plate-like structure. In this way, the material usage and deadweight of the mounting frame 1 can be further effectively reduced, thereby effectively saving manufacturing costs and effectively facilitating the transportation and use of the disassembly tool 100 for the fan impeller of the liquid ring pump of the present application.

[0050] In one embodiment of the present application, Figures 3 to 5As shown, the mounting frame 1 of the present application may further include a reinforcing plate 15, one end of the reinforcing plate 15 is connected to the second mounting plate 12 or the third mounting plate 13, and the other end of the reinforcing plate 15 is connected to the first mounting plate 11 or the fourth mounting plate 14. In this way, the structural stability of the mounting frame 1 can be effectively improved by the reinforcing plate 15 so arranged, thereby improving the structural integrity and durability of the mounting frame 1 of the present application.

[0051] In one embodiment of the present application, the reinforcement plate 15 of the present application can be set to two, one end of one of the two reinforcement plates 15 is connected to the second mounting plate 12, and the other end is connected to the fourth mounting plate 14, and one end of the other of the two reinforcement plates 15 is connected to the third mounting plate 13, and the other end is connected to the fourth mounting plate 14.

[0052] In another embodiment of the present application, the reinforcement plates 15 of the present application can be set to four, and the four reinforcement plates 15 are respectively set corresponding to the connection between the first mounting plate 11 and the second mounting plate 12, the connection between the first mounting plate 11 and the third mounting plate 13, the connection between the second mounting plate 12 and the fourth mounting plate 14, and the connection between the third mounting plate 13 and the fourth mounting plate 14.

[0053] In this way, by providing two or four reinforcement plates 15, the structural stability of the installation frame 1 can be further effectively improved, thereby further improving the structural integrity and durability of the installation frame 1 of the present application.

[0054] In one embodiment of the present application, Figure 5 As shown, the reinforcing plate 15 of the present application can be set as a plate-shaped structure with a triangular cross section. In this way, on the basis of ensuring the structural stability of the mounting frame 1, it is also beneficial to minimize the internal space of the mounting frame 1 occupied by the reinforcing plate 15, so as to facilitate the installation and removal of the ejection device 21.

[0055] In one embodiment of the present application, the connecting member 3 of the present application can be configured as a bolt. In this way, the connection between the mounting frame 1 and the impeller 201 is achieved by bolts, which not only ensures the connection strength, but also facilitates installation and disassembly.

[0056] In one embodiment of the present application, Figure 5As shown, the second through hole 112 and the third through hole 113 of the present application are symmetrically arranged about the first through hole 111, and the second through hole 112 and the third through hole 113 are formed as waist-shaped holes. In this way, through the second through hole 112 and the third through hole 113 arranged in this way, the connector 3 of the present application can have multiple optional penetration positions on the first mounting plate 11, so that it can effectively adapt to the disassembly needs of the impeller 201 of various models of liquid ring pump fans, and can effectively improve the versatility of the disassembly tool 100 for the impeller of the liquid ring pump fan of the present application.

[0057] In one embodiment of the present application, the ejection device 21 of the present application is detachably mounted on the fourth mounting plate 14. In this way, the installation and removal of the ejection device 21 can be realized very conveniently, so as to facilitate its installation, replacement or maintenance.

[0058] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
