[0001] The utility model relates to the technical field of disassembly tools, in particular to a water ring vacuum pump impeller removal tool used for electronic-grade chemicals. Background Art

[0002] Water ring vacuum pumps are widely used in the manufacturing process of electronic chemicals. They are suitable for pumping some chemicals with explosive gases to provide negative pressure requirements for the process, such as in the production process of electronic grade ammonia and isopropyl alcohol. After a long period of operation, the pump head of the water ring vacuum pump is prone to scale, which increases the resistance of the water ring vacuum pump when it rotates, thereby indirectly causing the current of the motor to increase when it is working. Therefore, it is necessary to regularly remove the impeller and clean the scaled part of the impeller;

[0003] At present, there is no special tool for removing the impeller, and the impeller shaft is mainly separated from the impeller by manual knocking. The knocking method can easily cause the impeller and the impeller shaft to deform, affecting the subsequent assembly and the service life of the impeller. For this reason, we propose a water ring vacuum pump impeller removal tool for electronic-grade chemicals. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a water ring vacuum pump impeller removal tool for electronic grade chemicals, which solves the problem that there is no special tool for removing the impeller, and the impeller shaft is mainly separated from the impeller by manual knocking. The knocking method easily causes deformation of the impeller and the impeller shaft, affecting the subsequent assembly and the service life of the impeller.

[0021] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0022] Embodiment:

[0023] like Figure 1-4 As shown, the utility model provides a water ring vacuum pump impeller removal tool for electronic grade chemicals, including an outer structure shell 1, a through hole 2 is opened at the bottom of the outer structure shell 1, a push rod 3 is sleeved inside the through hole 2, a small hydraulic component 4 is arranged on the upper end of the push rod 3, the small hydraulic component 4 is connected to an external hydraulic source, and the small hydraulic component 4 is placed in the outer structure shell 1 at the same time, connecting bolts 5 are respectively arranged on both sides of the inside of the through hole 2, and the connecting bolts 5 are connected to the external impeller. When the small hydraulic component 4 is working, the small hydraulic component 4 pushes the push rod 3, and the push rod 3 vertically pushes the impeller shaft under the restriction of the through hole 2 to make the impeller shaft and the impeller separated by displacement.

[0024] A height adjustment component for controlling the setting position of the small hydraulic component 4 is provided at the top of the outer structure shell 1, and the bottom of the height adjustment component is in conflict with the end of the small hydraulic component 4. The height adjustment component includes a screw hole 6, a screw rod 7 and a limit plate 8. The screw hole 6 is opened at the top of the outer structure shell 1, and the screw rod 7 is threadedly connected in the screw hole 6. The limit plate 8 is rotatably connected to the bottom end of the screw rod 7. The screw rod 7 drives the limit plate 8 to move through the threaded connection with the screw hole 6, thereby providing a support point for the setting of the small hydraulic component 4, so that the small hydraulic component 4 can be set at any point in the outer structure shell 1 to adapt to the working conditions at different points of the small hydraulic component 4, so that the small hydraulic component 4 can better disassemble and assemble impeller shafts of different specifications.

[0025] The limit plate 8 is coaxial with the small hydraulic component 4, and the bottom end of the limit plate 8 is ground. After the limit plate 8 contacts the small hydraulic component 4, the connection state can be kept stable by friction. The coaxial design can ensure that the limit plate 8 and the small hydraulic component 4 can be in normal contact, avoiding uneven force caused by docking deviation.

[0026] The height adjustment assembly also includes a screw knob 9, which is fixed at the top of the limit plate 8. The edge of the screw knob 9 is provided with a plurality of groups of grooves for gripping. The screw 7 can be conveniently rotated through the screw knob 9, thereby conveniently adjusting the setting position of the screw 7 and synchronously changing the setting position of the limit plate 8 set at the end of the screw 7, so that the limit plate 8 provides sufficient support for the small hydraulic assembly 4.

[0027] Both sides of the through hole 2 extend outward to form a slide groove for the connecting bolt 5 to slide. The connecting bolt 5 can slide on the surface of the through hole 2 according to the different setting positions of the holes on the impeller of the water ring vacuum pump until it slides to the position corresponding to the hole. The connecting bolt 5 is connected to the hole by rotation. With the cooperation of the through hole 2 and the connecting bolt 5, the outer structure shell 1 is fixedly connected to the impeller of the water ring vacuum pump, and the relative position between the two is kept fixed unchanged to ensure the next ejection operation.

[0028] Several groups of gripping holes 10 are provided on both sides of the outer structure shell 1. The staggered gripping holes 10 form several groups of gripping areas on the surface of the outer structure shell 1. The outer structure shell 1 can be easily grasped through the gripping areas, providing sufficient gripping space, thereby improving the convenience of using the device.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
