Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotor disassembly technology, and more specifically to a special disassembly tool for pressure screen rotors. Background Technology
[0002] Existing pressure screen rotors (3) require disassembly and maintenance after prolonged use. Due to the varying rotor sizes, traditional methods require a variety of tools, resulting in a wide range of tools, poor versatility, and inconvenience in carrying them (see [link]). Figure 4 Specifically, during disassembly, different sized tools need to be selected to match the rotor end face (33) of the rotor (3), which is cumbersome and inefficient. Therefore, there is an urgent need for a universal disassembly tool that can be adapted to rotors of different specifications. Utility Model Content
[0003] 1. Technical problem to be solved by the utility model
[0004] To address the aforementioned shortcomings in the disassembly of pressure screen rotors in existing technologies, this utility model provides a dedicated disassembly tool for pressure screen rotors. Through the cooperation of the base plate and the top rod, it can adapt to pressure screen rotors of different sizes, simplifying the operation and improving the disassembly efficiency.
[0005] 2. Technical Solution
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0007] A special disassembly tool for pressure screen rotor includes a base plate and a push rod. The base plate has a radial adjustment elongated hole on its surface and an internal threaded hole in the middle. The lower half of the push rod is a push-out screw. When disassembling the pressure screen rotor, the base plate is fixed to the pressure screen rotor by screwing the screw into the screw hole on the end face of the rotor. The pressure screen rotor is disassembled by rotating the threaded push rod and the internal threaded hole of the base plate.
[0008] A further technical solution involves multiple radially adjustable elongated holes symmetrically distributed around the internal threaded hole. The base plate can accommodate pressure screen rotors of different diameters, and the two are pressed and fixed together by the cooperation of the screw and the screw hole.
[0009] A further technical solution involves a stepped circular platform in the center of the base plate. When disassembling the pressure screen rotor, the platform is embedded in the circular groove in the center of the pressure screen rotor to prevent displacement and enhance the stability of the fixation.
[0010] A further technical solution involves a square head on the upper part of the push rod, which facilitates the application of force and rotation with a wrench.
[0011] A further technical solution involves a horizontally perforated hole in the square head, which can be used to assist rotation by inserting a crossbar.
[0012] A further technical solution involves using a cone-shaped end of the ejector screw to hold the end of the rotating shaft.
[0013] 3. Beneficial effects
[0014] Compared with the prior art, the technical solution provided by this utility model has the following advantages:
[0015] This utility model's special disassembly tool for pressure screen rotors achieves rapid adaptation of the base plate to rotors of different sizes through radial adjustment elongated holes; and provides stable linear thrust through the threaded engagement between the ejector screw and the base plate, avoiding damage to components caused by traditional impact disassembly; the square head and insertion hole design support manual or lever-assisted operation, improving disassembly efficiency and saving effort and convenience.

[0023] To further understand the contents of this utility model, a detailed description of the utility model is provided in conjunction with the accompanying drawings.
[0024] Example 1
[0025] The special disassembly tool for the pressure screen rotor in this embodiment, such as Figure 1 , 2 As shown in Figure 3, the device includes a base plate 1 and a push rod 2. The base plate 1 has a radial adjustment elongated hole 11 on its surface and an internal threaded hole 12 in its middle. The lower half of the push rod 2 is an ejector screw 21, the external thread of which matches the internal threaded hole 12 of the base plate 1. The radial adjustment elongated hole 11 is an elongated hole extending radially along the base plate 1 and is used to adjust the fixed position.
[0026] The special disassembly tool for the pressure screen rotor in this embodiment, such as Figure 4 When disassembling the pressure screen rotor 3 shown, the base plate 1 is pressed and fixed on the pressure screen rotor 3 by screwing the screw rod into the screw hole 34 of the rotor end face 33. The pressure screen rotor 3 is disassembled by rotating the threaded top rod 2 and the internal thread hole 12 of the base plate 1.
[0027] Example 2
[0028] The special disassembly tool for the pressure screen rotor in this embodiment has the same basic structure as in embodiment 1, with the following differences or improvements: Figure 1 , 2 As shown, the radial adjustment elongated holes 11 are arranged in multiple symmetrical radial patterns centered on the internal threaded holes 12. The base plate 1 can accommodate pressure screen rotors 3 of different diameters. The two are pressed and fixed together by the cooperation of screws and threaded holes 34. The center of the base plate 1 has a stepped circular insert 13, a raised structure at the bottom of the base plate. The base plate 1 is fixed by screws passing through the radial adjustment elongated holes 11 and threaded holes 34 on the rotor end face 33. When disassembling the pressure screen rotor 3, the insert 13 is embedded in the circular groove 32 in the center of the pressure screen rotor 3 to prevent displacement and enhance the stability of the fixation. Figure 2 As shown, the upper part of the push rod 2 is a square head 22, which makes it easy to apply force and rotate with a wrench.
[0029] Example 3
[0030] The special disassembly tool for the pressure screen rotor in this embodiment has the same basic structure as in embodiment 2, with the following differences or improvements: Figure 3 As shown, the square head 22 has a transverse hole 23 through which a crossbar can be inserted to assist rotation. The end of the ejector screw 21 is a cone head 24, which is aligned with the end of the rotating shaft 31 and used to hold the rotating shaft 31 in place. When the ejector rod 2 is rotated, the ejector screw 21 is pushed forward along the thread, and the force applied by the cone head 24 separates the rotating shaft 31 from the pressure screen rotor 3.
[0031] The disassembly steps are as follows:
[0032] Install the base plate: According to the diameter of the pressure screen rotor 3, adjust the screw to pass through the radial adjustment elongated hole 11 of the base plate 1, fix it to the screw hole 34 of the rotor end face 33, and ensure that the insert 13 is inserted into the groove 32;
[0033] Assemble the ejector rod: Screw the ejector screw 21 of the ejector rod 2 into the internal thread hole 12 of the base plate 1, so that the cone 24 contacts the end of the rotating shaft 31;
[0034] Disassembly by force: Rotate the square head 22 with a wrench or insert the lever into the socket 23, rotate the top rod 2 clockwise, push out the screw 21 to push the rotating shaft 31 away from the pressure screen rotor 3.
[0035] The special disassembly tool for pressure screen rotors in this embodiment can be adapted to pressure screen rotors 3 of different sizes by adjusting the fixed position of the base plate 1 and the pushing amount of the top rod 2, thus achieving "one tool for multiple uses" and significantly improving disassembly and maintenance efficiency.
[0036] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention. The actual structure and manufacturing steps are not limited to these. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
