Description
Technical Field
[0001] The utility model relates to a straightening device, in particular to an atomizer main shaft straightening device. Background Art
[0002] Rotary atomization technology uses high-speed rotating equipment to atomize liquid feed into micron-sized droplets. The core device is the rotary atomizer. Rotary atomizers are widely used in the chemical, pharmaceutical, food, and environmental protection industries. In the field of air pollution control and environmental protection, rotary atomizers are used for flue gas desulfurization in power plants and exhaust gas purification in waste incineration power plants. With the rise of waste incineration power generation and the widespread construction of waste incineration power plants, rotary atomizers have become even more widely used.
[0003] Then, the existing atomizer has the following deficiencies:
[0004] Since the main shaft of the atomizer is relatively long and has a high rotation speed during operation, the main shaft has a large amplitude and is prone to bending and deformation after long-term operation, affecting working performance. In addition, the existing method for dealing with a bent main shaft is to directly replace it with a new one, which is very costly. Utility Model Content
[0005] The purpose of the utility model is to overcome the above-mentioned problems and provide an atomizer main shaft straightening device, which can straighten the bent main shaft of the atomizer and recycle it without replacing a new main shaft, thereby reducing the use cost.
[0006] The purpose of the utility model is achieved through the following technical solutions:
[0007] An atomizer main shaft straightening device comprises a workbench and a supporting mechanism and a pressing mechanism arranged on the workbench;
[0008] The support mechanism includes a support seat, at least two of which are provided, each of which is provided with a positioning groove for placing the main shaft;
[0009] The pressing mechanism includes a pressing frame, a pressing head arranged on the pressing frame, and a hydraulic press for driving the pressing head to press down the main shaft.
[0010] The working principle of the above-mentioned atomizer main shaft straightening device is:
[0011] When working, first place the main shaft of the atomizer horizontally on the support seat, with the bent part of the main shaft facing vertically upward. At this time, the main shaft is located in the positioning groove to prevent the main shaft from moving around; the hydraulic press drives the lower pressure head downward to approach the bent part of the main shaft, and then the lower pressure head presses the bent part of the main shaft downward, gradually reducing the bending angle until the bent part of the main shaft is straightened.
[0012] In a preferred embodiment of the present invention, the support mechanism further comprises a support sliding structure comprising two parallel support sliding guide rails, with sliding portions cooperating with the support sliding guide rails being provided on both sides of the bottom of the support base. This structure allows the relative position of the support base to be adjusted horizontally so that it is positioned appropriately to support the spindle.
[0013] In a preferred embodiment of the present invention, the support mechanism further comprises an anti-overpressure limit assembly for preventing the main shaft from being over-pressurized, and the anti-overpressure limit assembly is located directly below the hydraulic press.
[0014] Furthermore, the anti-overpressure limit assembly includes a base, a limit support block, and a vertical movement structure; the vertical movement structure includes a transverse slider and a transverse screw, the transverse screw being laterally rotatably connected to the base and engaging with the transverse slider via a threaded structure; the base is provided with a lifting installation slot, in which the transverse slider and the limit support block are both located; the limit support block is located above the transverse slider, the bottom surface of the limit support block being an upper transmission inclined surface, and the top surface of the transverse slider being a lower transmission inclined surface engaging with the upper transmission inclined surface; the lifting installation slot is provided with two side walls for guiding the limit support block. Through the above structure, rotating the transverse screw can drive the transverse slider to move laterally on the bottom surface of the lifting installation slot, and then the cooperation between the upper transmission inclined surface and the lower transmission inclined surface can drive the limit support block to move vertically, thereby adjusting the height of the limit support block, performing overpressure limiting on spindles with different degrees of curvature, and preventing the spindle from being excessively squeezed.
[0015] Furthermore, the base is provided with a limiting plate for limiting the limiting support block in the lifting installation slot.
[0016] Furthermore, a downward return spring is provided above the position-limiting support block, with both ends of the downward return spring respectively pressed against the downward return mounting plate and the position-limiting support block. Thus, when the position-limiting support block is adjusted downward, the downward return spring provides auxiliary force, prompting the position-limiting support block to move downward, making the adjustment operation easier.
[0017] Furthermore, a micrometer is connected to the limit support block, and the detection head of the micrometer is vertically arranged upward. In this way, the size of the main shaft extrusion reset can be detected in real time by the micrometer to ensure that the main shaft is accurately straightened.
[0018] In a preferred embodiment of the present invention, the pressing mechanism further comprises a pressing adjustment structure comprising a pressing adjustment bracket and a pressing adjustment roller. The pressing adjustment roller is rotatably connected to the pressing adjustment bracket, which is fixedly connected to the bottom of the pressing frame. The bottom of the pressing adjustment bracket is provided with a limit portion for buckling onto a workbench. Two sets of the pressing adjustment bracket and the pressing adjustment roller are provided. This structure allows the relative position of the hydraulic press to be adjusted horizontally, placing it in an appropriate position for pressing the main shaft.
[0019] A preferred embodiment of the present invention is that the pressing mechanism further comprises a pressing movable mounting frame and an ascending return spring, wherein the pressing movable mounting frame can be vertically slidably connected to the pressing frame, the hydraulic press is fixedly arranged on the top surface of the pressing movable mounting frame, and the outer end of the telescopic rod of the hydraulic press is pressed upward on the pressing frame; the pressing head is fixedly arranged on the bottom surface of the pressing movable mounting frame; and the upper and lower ends of the ascending return spring are respectively connected to the pressing frame and the pressing movable mounting frame. Through the above structure, after the hydraulic press is started, the telescopic rod of the hydraulic press is pressed against the pressing frame and remains stationary, and the housing of the hydraulic press drives the pressing movable mounting frame to move downward, thereby driving the pressing head to squeeze the main shaft, at which time the ascending return spring deforms and stores energy. After the straightening is completed, the hydraulic press begins to contract, and the ascending return spring begins to release potential energy, driving the pressing movable mounting frame and the pressing head to reset upward.
[0020] A preferred embodiment of the present invention further includes a rolling support mechanism, wherein the rolling support mechanism is provided with two groups, and each group includes a support seat and a support roller. The same group of support rollers is provided with two and is rotatably connected to the support seat in parallel. Through the above structure, before straightening, the main shaft can be placed on the two support seats, and then the main shaft can be rotated. The surface runout of the main shaft can be detected using a micrometer to find the highest point of the bending part of the main shaft so that the pressure point can be accurately selected for straightening later. Among them, due to the large weight of the main shaft, it requires a lot of effort to rotate it by hand, which is inconvenient. Therefore, the main shaft can be easily rotated by rolling with the support roller, which saves effort and is more accurate.
[0021] Furthermore, each set of rolling support mechanisms also includes a lifting drive cylinder, the telescopic rod of which is connected to the corresponding support seat. This can drive the support seat to move up and down, allowing the spindle to be lifted first, rotated to determine the bending position, and then lowered to transfer the spindle to the support seat, which is very convenient.
[0022] Compared with the prior art, the present invention has the following beneficial effects:
[0023] The straightening device of the utility model can straighten the bent main shaft of the atomizer and recycle it without replacing a new main shaft, thereby reducing the use cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.
[0028] See also Figure 1-2 The atomizer spindle straightening device of this embodiment includes a workbench 1 and a support mechanism, a pressing mechanism, and a rolling support mechanism disposed on the workbench 1. The support mechanism includes a support base 2, at least two of which are provided, each of which is provided with a positioning groove 2-1 for placing the spindle. The support mechanism also includes a support sliding structure, which includes two parallel support sliding guide rails 3. Both sides of the bottom of the support base 2 are provided with sliding portions that cooperate with the support sliding guide rails 3. Through the above structure, the relative position of the support base 2 can be adjusted horizontally to place it in the appropriate position to support the spindle.
[0029] See also Figure 3-4The support mechanism also includes an anti-overpressure limit assembly for preventing the main shaft from over-pressurizing. The anti-overpressure limit assembly is located directly below the hydraulic press 14. Furthermore, the anti-overpressure limit assembly includes a base 4, a limit support block 5, and a vertical movable structure. The vertical movable structure includes a transverse slider 6 and a transverse screw 7. The transverse screw 7 is connected to the base 4 for transverse rotation and cooperates with the transverse slider 6 through a threaded structure. The base 4 is provided with a lifting installation slot, and the transverse slider 6 and the limit support block 5 are both located in the lifting installation slot. The limit support block 5 is located above the transverse slider 6. The bottom surface of the limit support block 5 is an upper transmission inclined surface, and the top surface of the transverse slider 6 is a lower transmission inclined surface that cooperates with the upper transmission inclined surface. The lifting installation slot is provided with two side walls for guiding the limit support block 5. Through the above structure, by rotating the transverse screw 7, the transverse slider 6 can be driven to move laterally on the bottom surface of the lifting installation slot, and then the limit support block 5 is driven to move vertically through the cooperation between the upper transmission inclined surface and the lower transmission inclined surface, so that the height of the limit support block 5 can be adjusted, and the over-pressure limit can be performed on the main shaft with different bending degrees to prevent the main shaft from being excessively squeezed.
[0030] Furthermore, a limiting plate 8 is provided on the base 4 for limiting the limiting support block 5 in the lifting installation slot.
[0031] See also Figure 3-4 A downward return spring 9 is provided above the position-limiting support block 5, with both ends of the downward return spring 9 respectively pressed against the downward return mounting plate 10 and the position-limiting support block 5. Thus, when the position-limiting support block 5 is adjusted downward, the downward return spring 9 provides an auxiliary force to urge the position-limiting support block 5 downward, making the adjustment operation easier.
[0032] See also Figure 3-4 The limit support block 5 is connected with a dial gauge 11, and the detection head of the dial gauge 11 is vertically upwardly arranged. In this way, the size of the main shaft extrusion reset can be detected in real time by the dial gauge 11 to ensure that the main shaft is accurately straightened.
[0033] See also Figure 1-2The pressing mechanism includes a pressing frame 12 and a pressing head 13 arranged on the pressing frame 12, a hydraulic press 14 (a manual hydraulic press can be used), a pressing movable mounting frame 15, and an ascending return spring 16; the pressing movable mounting frame 15 can be vertically slidably connected to the pressing frame 12, the hydraulic press 14 is fixedly arranged on the top surface of the pressing movable mounting frame 15, and the outer end of the telescopic rod of the hydraulic press 14 is pressed upward on the pressing frame 12; the pressing head 13 is fixedly arranged on the bottom surface of the pressing movable mounting frame 15; the upper and lower ends of the ascending return spring 16 are respectively connected to the pressing frame 12 and the pressing movable mounting frame 15. Through the above structure, after the hydraulic press 14 is started, the telescopic rod of the hydraulic press 14 is pressed against the pressing frame 12 and remains motionless, and the shell of the hydraulic press 14 drives the pressing movable mounting frame 15 to move downward, thereby driving the pressing head 13 to squeeze the main shaft, and at this time the ascending return spring 16 deforms and stores energy. After the straightening is completed, the hydraulic press 14 begins to contract, and the upward return spring 16 begins to release potential energy, driving the downward moving mounting frame 15 and the downward pressing head 13 to return upward.
[0034] See also Figure 1-2 , see Figure 1-2 The pressing mechanism also includes a pressing adjustment structure, comprising a pressing adjustment bracket 17 and a pressing adjustment roller 18. The pressing adjustment roller 18 is rotatably connected to the pressing adjustment bracket 17, which is fixedly connected to the bottom of the pressing frame 12. The bottom of the pressing adjustment bracket 17 is provided with a limiter for buckling onto the workbench 1. Two sets of the pressing adjustment bracket 17 and the pressing adjustment roller 18 are provided. This structure allows the relative position of the hydraulic press 14 to be adjusted horizontally, placing it in the appropriate position to compress the main shaft.
[0035] See also Figure 1-2 The rolling support mechanism is provided with two groups, and each group includes a support seat 19 and a support roller 20. The same group of support rollers 20 is provided with two and is rotatably connected to the support seat 19 in parallel. Through the above structure, before straightening, the main shaft can be placed on the two support seats 19, and then the main shaft can be rotated. The surface runout of the main shaft can be detected using a dial indicator to find the highest point of the main shaft bending part so that the pressure point can be accurately selected for straightening later. Among them, due to the heavy weight of the main shaft, it requires a lot of effort to rotate it by hand, which is inconvenient. Therefore, the support roller 20 is used to assist in rolling, which can easily rotate the main shaft, save effort, and achieve higher accuracy.
[0036] Furthermore, each set of rolling support mechanisms also includes a lifting drive cylinder 21, the telescopic rod of which is connected to the corresponding support seat 19. This can drive the support seat 19 to move up and down, so that the main shaft can be lifted first, and after the main shaft is rotated to determine the bending position, it can be lowered and placed on the support seat 2, which is very convenient.
[0037] See also Figure 1-2 The working principle of the atomizer main shaft straightening device of this embodiment is:
[0038] During operation, first place the main shaft of the atomizer horizontally on the support seat 2, with the bent part of the main shaft facing vertically upward. At this time, the main shaft is located in the positioning groove 2-1, which can prevent the main shaft from moving around; the hydraulic press 14 drives the lower pressure head 13 downward to approach the bent part of the main shaft, and then the lower pressure head 13 presses the bent part of the main shaft downward, gradually reducing the bending angle until the bent part of the main shaft is straightened.
[0039] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content.
