Description

Technical Field

[0001] The invention relates to the technical field of impeller performance detection, and in particular to an impeller performance testing device and a testing method for an evaporator used for battery sewage treatment. Background Art

[0002] Common batteries on the market include dry batteries, lead-acid batteries, lithium batteries, etc. Although the types of batteries are different, some of the raw materials used in the production process are the same. The wastewater generated during the production process contains some toxic pollutants. Therefore, battery wastewater needs to be effectively treated in a timely manner to avoid affecting the environment. There are different ways to treat battery wastewater, but through continuous improvement and optimization, in order to meet the needs of different customers, a new generation of wastewater treatment processes with MVR / multi-effect evaporator series products as the core have gradually been introduced on the market.

[0003] Among them, in the process of treating battery wastewater, the MVR evaporator will reuse the residual heat of the secondary steam for the use of the equipment, inhale the steam from the separator through the compressor, and compress it again to increase the pressure and temperature of the steam when it is discharged, so that the secondary steam can be used again like fresh steam, so the compressor fan is one of the important components of the MVR evaporator system. Then, in the process of recycling the secondary steam, because the steam contains some impurities such as dust particles and chemical molecules, with the continuous repeated circulation, it will continue to deposit or adhere on the surface of the blade during the flow process, resulting in the continuous thickening of the blade thickness, and due to some chemical molecules in the steam, the blade will also be affected by its continuous erosion and gradually become thinner during the continuous working process, and then with the change of the blade thickness, the impeller will vibrate in its radial direction, and although the blade thickness has little effect on the horizontal vibration, it may still occur when the radial vibration causes the misalignment of the shaft or other bearing-related problems. However, the relevant test equipment for impeller performance on the market cannot simulate the impact of the change in impeller thickness, and cannot detect the impact of the change.

[0004] Therefore, it is necessary to provide an impeller performance test device and a test method for an evaporator for battery wastewater treatment to solve the problems raised. Summary of the invention

[0017] In one embodiment, when the impeller simulation assembly generates radial vibration, the fixed roller begins to vibrate and simultaneously drives the movable arm to move and adjust along the length direction of the fixed box, so that the movable part 1 at the end of the movable arm makes a linear reciprocating motion along the rack under the driving action of the movable arm, thereby amplifying the amplitude of the vibration through the displacement distance of the movable part 1.

[0018] In one embodiment, the lateral vibration amplification assembly includes a top plate, an adjustment arm 1, a lever arm, an adjustment arm 2, and a moving part 2.

[0022] In one embodiment, when the top plate moves away from the impeller simulation component, the angle between the adjusting arm 1 and the lever arm, as well as the angle between the adjusting arm 2 and the lever arm, both begin to decrease at the same time; when the top plate moves toward the impeller simulation component, the angle between the adjusting arm 1 and the lever arm, as well as the angle between the adjusting arm 2 and the lever arm, both begin to increase at the same time; as the angle changes, the moving part 2 undergoes a displacement movement synchronously with the drive of the adjusting arm 2.

[0023] The test method of the impeller performance test equipment of the evaporator for battery wastewater treatment comprises the following steps:

[0024] S1. First, move the lateral vibration amplification components on both sides to the sides respectively, and temporarily fix the position of the lateral vibration amplification components by means of set screws. Then, install the impeller simulation component on the key shaft 2 and fix it, and make the key shaft 1 and the output gear correspond to each other. After the installation is completed, loosen the set screws to reset the lateral vibration amplification component and make it contact with the impeller simulation component.

[0025] S2, then, the second rotating motor is started through the PLC controller, so that the input gear starts to rotate, thereby driving the driving ring to rotate. Under the action of the driving ring, the output gear rotates synchronously therewith, and drives the adjustment piece connected thereto to rotate and adjust, thereby changing the thickness of the blade structure. When the thickness is adjusted to an appropriate thickness, the second rotating motor is stopped;

[0026] S3. Then, the rotating motor 1 is started through the PLC controller, so that the output shaft starts to rotate, thereby driving the impeller simulation component to rotate synchronously. During the rotation process, the detection parts of the radial vibration amplification component and the lateral vibration amplification component are in contact with the circumferential outer surface of the impeller simulation component. When the impeller simulation component produces radial or horizontal vibrations due to changes in thickness, the radial vibration amplification component and the lateral vibration amplification component detect the vibrations in these two directions respectively, and amplify the vibration amplitude generated by displacement motion, so that the inspection personnel can find problems more clearly and significantly.

[0027] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0028] 1. The present invention sets an impeller simulation component and an adjustment component, and uses the adjustment component to simultaneously adjust the angles of several adjustment plates in the impeller simulation component, so that the detection device can directly simulate the situation that the thickness of the impeller blades increases due to the deposition and adhesion of components in the sewage on the surface, or the thickness of the blades becomes thinner due to the continuous erosion of chemical substances in the sewage, and performs vibration detection through the detection mechanism, so as to better and more comprehensively detect the impact of the change in the thickness of the impeller blades on the overall operation of the impeller.

[0029] 2. The present invention sets up a radial vibration amplification component and a lateral vibration amplification component. The former uses a fixed roller to detect the radial direction of the impeller simulation component, and transmits the vibration to the movable part one through a movable arm, and finally uses the displacement movement of the movable part one on the rack to respond to the radial vibration effect; the latter uses the top plate to detect the horizontal direction of the impeller simulation component, and uses the lever arm to amplify the lateral vibration amplitude and respond to the lateral vibration effect by the displacement movement of the movable part two.

[0045] like Figure 3-4 As shown, the impeller simulation assembly 2 includes a front mounting plate 21, a rear mounting plate 22 and a blade structure 23;

[0046] The front mounting plate 21 and the rear mounting plate 22 are both arranged in a circular plate structure with equal diameters, and a through hole is opened at the center position of the front mounting plate 21, and a key hole is opened at the center position of the rear mounting plate 22. The key shaft 2 312 on the output shaft 311 is installed in the key hole, so that the impeller simulation component 2 can move under the drive of the rotating motor 1 31.

[0047] The blade structure 23 is installed between the front mounting plate 21 and the rear mounting plate 22, and a plurality of blade structures 23 are arranged at equal angles with the center of the impeller simulation component 2 as the center of the circle. The blade structure 23 includes an adjusting piece 231 and a fixing piece 232. A connecting ring 2321 connected to the fixing piece 232 is arranged on one end of the fixing piece 232 facing the center of the front mounting plate 21. A connecting ring 1 2311 connected to the fixing piece 232 is arranged on one end of the adjusting piece 231 facing the center of the front mounting plate 21. Two connecting rings 1 2311 are arranged. The connecting rings 2321 are the same size as the connecting rings 1 2311, and the connecting rings 1 2311 are located between the two connecting rings 2321 and the connecting rings 1 2311. 321, and a mounting shaft (not shown in the figure) is coaxially arranged between the connecting ring 1 2311 and the connecting ring 2 2321, one end of the mounting shaft is fixedly welded to the front mounting plate 21, the connecting ring 1 2311 and the mounting shaft are rotatably arranged, the connecting ring 2 2321 and the mounting shaft are fixedly connected, and a key shaft 24 connected to it is also installed on the end of the connecting ring 1 2311 facing the side of the rear mounting plate 22, one end of the key shaft 24 is an axial structure, and is penetrated and rotatably arranged between the inner walls of the rear mounting plate 22, and a key strip is arranged on the other end of the key shaft 24 and is exposed.

[0048] The adjusting piece 231 is rotated and adjusted around the axis of the mounting shaft on one side of the fixed piece 232, and an adjusting spring is also arranged between the side walls of the adjusting piece 231 and the fixed piece 232, and the two ends of the adjusting spring are respectively fixed on the side walls of the adjusting piece 231 and the fixed piece 232, wherein a side membrane 233 is also connected between one end of the adjusting piece 231 and the fixed piece 232, and one end of the side membrane 233 is installed in the end of the fixed piece 232 through a membrane shaft, and the membrane shaft can be automatically reset through a torsion spring (not shown in the figure), and the other end of the side membrane 233 is connected and fixed to one end of the adjusting piece 231 as a whole.

[0049] It should be further explained that when the adjusting piece 231 is pressed Figure 4 When the adjusting piece 231 rotates counterclockwise as shown, that is, the adjusting piece 231 moves toward the side away from the fixing piece 232, during this process, the overall thickness of the blade structure 23 gradually increases, and at the same time, one end of the side film 233 is also pulled out of the fixing piece 232 as the adjusting piece 231 rotates, until the adjusting piece 231 stops moving; conversely, the overall thickness of the blade structure 23 gradually decreases, and at the same time, under the action of the torsion spring, one end of the side film 233 located inside the fixing piece 232 automatically reels the pulled-out part during the process of the adjusting piece 231 approaching the fixing piece 232 until the adjusting piece 231 stops moving.

[0050] like Figure 5-7As shown, the detection mechanism 4 includes a fixing frame three 42, a radial vibration amplifying component 43 and a lateral vibration amplifying component 44. The bottom end of the fixing frame three 42 is fixed to the detection platform 1 by bolts. A mounting groove is also opened on one side of the fixing frame three 42 on the detection platform 1. Vertically arranged guide plates 13 are installed on both sides of the mounting groove by screws, and a fixing bar 12 is also installed on the detection platform 1 by bolts at a position opposite to the fixing frame three 42. A fixing rod 41 is installed between the fixing frame three 42 and the fixing bar 12. One end of the fixing rod 41 is welded and fixed to the top surface of the fixing bar 12, and the other end of the fixing rod 41 passes through the fixing frame three 42 and is connected and fixed by a nut.

[0051] The radial vibration amplifying component 43 includes a rack 431, a fixing seat 432, an elastic component, a fixing roller 435 and a moving part 436;

[0052] The elastic component includes an adjusting box 433 and a movable arm 434. One end of the adjusting box 433 is opened, and a limiting rod 4331 is welded on the inner wall of the other end of the adjusting box 433 along its length direction. The length of the limiting rod 4331 is equal to the length of the adjusting box 433. A tension spring is sleeved on the outside of the limiting rod 4331, one end of the tension spring is fixed on the adjusting box 433, one end of the movable arm 434 is always slidably adjusted along the inner wall of the adjusting box 433, and the other end of the tension spring is connected and fixed to one end of the movable arm 434 located in the adjusting box 433, and one end of the limiting rod 4331 is inserted into the movable arm 434.

[0053] The rack 431 is fixed between the inner walls of the mounting groove by screws, and a fixing seat 432 is fixed with screws in the vertical direction of the fixing rod 41, and a sleeve 4321 is threadedly installed on one end of the fixing seat 432 facing the elastic component, and a rotating shaft is threadedly connected on the side wall of the adjusting box 433 facing the fixing seat 432, and the other end of the rotating shaft is in a "T" shape and is rotatably arranged between the inner walls of the sleeve 4321.

[0054] A fixed roller 435 is installed between the side walls of the adjusting arms on both sides through an axis connection, and the fixed roller 435 is arranged in contact with the circumferential side of the impeller simulation component 2. A moving part 436 is also installed between the side walls of the adjusting arms on both sides through an axis connection. The moving part 436 is a gear, and the moving part 436 is meshed on the rack 431. The axis passing through the moving part 436 passes through the guide plates 13 on both sides and is slidably arranged along the inner wall of the guide plate 13.

[0055] It should be further explained that, during installation, the fixed boxes on both sides are respectively placed on both sides of the impeller simulation component 2, and the fixed roller 435 is moved with the movable arm 434 to a position in contact with the circumferential outer surface of the impeller simulation component 2 under the action of the tension spring, and then when the impeller simulation component 2 generates radial vibration, the fixed roller 435 is driven to vibrate, and with the vibration of the fixed roller 435, the movable arm 434 continuously slides back and forth between the inner walls of the fixed box. In this process, since the moving part 436 and the fixed roller 435 are both installed on the movable arms 434 on both sides, 34, so that when the movable arm 434 moves, the movable member 436 will also move accordingly, but because the movable member 436 is restricted by the guide plates 13 on both sides and the setting of the rotating shaft, it is possible to better facilitate the movement of the adjustment box 433 and the movable arm 434, so that when the movable member 436 vibrates radially, the movable member 436 continuously moves back and forth along the rack 431, and then the length change of the tension spring that is not easy to observe can be more significantly represented by the displacement movement of the movable member 436 on the rack 431.

[0056] The lateral vibration amplifying assembly 44 includes a top plate 441, an adjusting arm 1 443, a lever arm 445, an adjusting arm 2 447 and a moving member 2 448;

[0057] A crossbeam 421 is welded on a side wall of the fixing frame 3 42 facing the detection mechanism 4 , and a transverse hole is opened on the crossbeam 421 along its length direction.

[0058] The top plate 441 is arranged in an arc-shaped structure, and movable seats 442 are arranged on the side walls on both sides of the top plate 441. The movable seats 442 slide on the fixed rod 41 and can be connected and fixed by tightening screws. A compression spring is sleeved on the fixed rod 41 on one side of the movable seat 442, and the other end of the compression spring is fixed to the side wall of the fixed frame three 42. A through shaft (not shown in the figure) installed between the movable seats 442 on both sides passes through the middle of the top plate 441, so that the top plate 441 is connected with the movable seats 442 on both sides as a whole. The side wall of the top plate 441 facing the fixed frame three 42 is screwed on the side wall of the top plate 441 A connecting seat 4411 is installed with a thread, and adjusting arms 443 are provided on both sides of the connecting seat 4411. A connecting shaft 1 is connected between the adjusting arms 443 on both sides, and the connecting shaft 1 penetrates and is rotatably arranged between the inner walls of the connecting seat 4411. A lever arm 445 is arranged at the other end of the adjusting arms 443 on both sides, and a connecting shaft 2 is installed between the other ends of the adjusting arms 443 on both sides, and the connecting shaft 2 also penetrates one end of the lever arm 445, and a synchronous wheel 444 is keyed on one end of the connecting shaft 2, and the movement of the adjusting arm 443 and the synchronous wheel 444 are synchronized.

[0059] The lever arm 445 is rotatably arranged on one side wall of the crossbeam 421 through an axis connection, and a synchronous wheel 2 446 and an adjusting arm 2 447 are respectively arranged on both sides of the other end of the lever arm 445, and a connecting shaft 3 is connected between the synchronous wheel 2 446 and the adjusting arm 2 447, and the connecting shaft 3 also penetrates the inner wall of the lever arm 445 and is rotatably arranged therewith, and the synchronous wheel 2 446 and the adjusting arm 2 447 move synchronously, wherein the synchronous wheel 1 444 and the synchronous wheel 2 446 are located on the same side of the lever arm 445, and a toothed belt is also installed therebetween, and the diameter ratio of the synchronous wheel 1 444 to the synchronous wheel 2 446 is 1:1, and a rotatably arranged connecting shaft 4 (see Figure 7 The second movable part 448 is arranged along the length direction of the beam 421, and the second movable part 448 is arranged in a "U"-shaped structure. The other end of the connecting shaft four is fixed on the side wall of the second movable part 448 facing the beam 421, and the connecting shaft four is arranged to slide along the inner wall of the transverse hole.

[0060] In addition, the distance from the rotation center of the lever arm 445 to the center of the synchronous wheel 1 444 is smaller than the distance from the rotation center of the lever arm 445 to the center of the synchronous wheel 2 446 .

[0061] It should be further explained that, when the impeller simulation component 2 generates radial vibration, a small lateral vibration may also be generated. When the lateral vibration is generated, the top plate 441 moves linearly along the horizontal direction as the vibration is generated.

[0062] When the top plate 441 is Figure 7 When the left side moves as shown, the moving seat 442 compresses the compression spring. At this time, the angle between the adjusting arm 1 443 and the lever arm 445 begins to decrease. Therefore, under the action of the synchronous wheel 1 444, the synchronous wheel 2 446 and the toothed belt, the angle between the adjusting arm 2 447 and the lever arm 445 also decreases, so that the connecting shaft 4 moves along the transverse hole to the side away from the fixing frame 3 42, and then the moving member 2 448 moves and adjusts synchronously; on the contrary, when the top plate 441 moves to the left side, the moving member 2 448 moves synchronously; on the contrary, when the top plate 441 moves to the right side, the moving member 2 448 moves .... Figure 7 When the right side moves as shown, the compression spring applies a reverse force to the movable seat 442. At this time, the angle between the adjusting arm 1 443 and the lever arm 445, and the angle between the adjusting arm 2 447 and the lever arm 445 increase synchronously, so that the connecting shaft 4 drives the movable member 2 448 to move and adjust along the beam 421 toward the side close to the fixed frame 3 42.

[0063] like Figure 8-9 As shown, the adjustment assembly 5 includes a drive ring 51, an output gear 52 and an input gear 53;

[0064] A second rotating motor 531 is installed on one side wall of the second fixing frame 32 by bolts. An input gear 53 is rotatably disposed on the other side wall of the second fixing frame 32 , and the second rotating motor 531 is connected to the input gear 53 for driving.

[0065] Two symmetrically arranged limit bolts 321 are installed on the side wall of the fixed frame 2 32 facing the impeller simulation component 2 through threaded connection. The limit bolt 321 is an axial structure, and a limit ring 322 connected to it is also installed on the outer surface of the limit bolt 321. An annular groove 512 is provided on the side wall of the driving ring 51 facing the fixed frame 2 32. The limit bolt 321 is located in the annular groove 512 and is in rotational contact with it. The limit ring 322 is in rotational contact with the inner wall of the driving ring 51, and a groove matching the limit ring 322 is also provided in the annular groove 512. The limit bolt 321 and the limit ring 322 are used to assist in limiting the position of the driving ring 51 on the fixed frame 2 32, and at the same time, the rotation adjustment of the driving ring 51 will not be affected.

[0066] An external tooth groove 511 meshing with the input gear 53 is provided on the circumferential outer surface of the driving ring 51. The driving ring 51 is located directly above the input gear 53 and is meshed with it for transmission. A groove is provided on the side of the driving ring 51 facing the impeller simulation component 2. Internal teeth are provided on the inner wall of the groove, and a plurality of output gears 52 are evenly distributed in the groove along the circumferential direction. Each output gear 52 is respectively mounted on the corresponding key shaft 24, and adjacent output gears 52 do not contact each other. The output gear 52 is meshed with the internal teeth for transmission, and a side wall of the output gear 52 is in contact with the rear mounting plate 22.

[0067] It should be further explained that the rotating motor 2 531 is started by the PLC controller to control the rotation drive of the input gear 53, thereby controlling the rotation of the drive ring 51. As the drive ring 51 rotates, the multiple output gears 52 inside it rotate synchronously and in the same direction, and then respectively drive the corresponding connecting ring 1 2311 connected thereto to rotate through the key shaft 1 24, thereby controlling the angle adjustment of the adjusting plate 231. After adjusting to the appropriate angle according to the test requirements, the rotating motor 2 531 can be stopped.

[0068] The test method of the impeller performance test equipment of the evaporator for battery wastewater treatment comprises the following steps:

[0069] First, move the top plates 441 on both sides to the sides respectively. After moving to the appropriate position, temporarily fix the position of the top plates 441 by tightening screws. Then, install the impeller simulation assembly 2 on the key shaft 2 312 so that the rear mounting plate 22 and the key shaft 2 312 are key-connected and fixed. At the same time, adjust the angle of the impeller simulation assembly 2 so that the key shaft 1 24 and the output gear 52 are installed together in a one-to-one correspondence. After the installation is completed, loosen the tightening screws to reset the top plate 441 and make contact with the impeller simulation assembly 2.

[0070] Next, the rotating motor 2 531 is started through the PLC controller, so that the input gear 53 starts to rotate, thereby driving the driving ring 51 to rotate. Under the action of the driving ring 51, the output gear 52 rotates synchronously with the rotation of the internal teeth on the driving ring 51, and the output gear 52 and the connecting ring 1 2311 are connected as a whole through the key shaft 1 24, so that when the output gear 52 rotates, the connecting ring 1 2311 drives the adjusting plate 231 to rotate synchronously, and the adjusting plate 231 makes a circular motion around the center of the mounting shaft. When the adjusting plate 231 rotates and adjusts to the side away from the fixed plate 232, the thickness of the blade structure 23 begins to increase, and vice versa. When the thickness of the blade structure 23 is adjusted to an appropriate level, the rotating motor 2 531 can be stopped.

[0071] Then, the rotating motor 31 is started through the PLC controller, so that the output shaft 311 starts to rotate, and the output shaft 311 drives the connected impeller simulation component 2 to rotate synchronously through the key shaft 24. During the rotation process, the fixed roller 435 and the top plate 441 are respectively in contact with the circumferential outer surface of the impeller simulation component 2. When the impeller simulation component 2 produces radial vibration due to the change in thickness, the fixed roller 435 slides and adjusts along the inner wall of the adjustment box 433, thereby synchronously driving the movement of the moving part 436 through the movable arm 434. Under the restriction of the guide plate 13, the moving part 436 can only move linearly along the rack 431 when it moves with the movable arm 434, so that the linear movement distance of the moving part 436 reflects the amplitude of the radial vibration; when the impeller simulation component 2 produces horizontal vibration due to the change in thickness, the top plate 441 moves accordingly. It moves and adjusts along the horizontal straight line direction, thereby driving the adjustment arm 443 on one side to move, and the adjustment arm 443 drives the synchronous wheel 444 to rotate and adjust synchronously, and the synchronous wheel 444 drives the synchronous wheel 446 to move synchronously through the toothed belt, and the synchronous wheel 446 and the adjustment arm 447 move synchronously, so that the top of the adjustment arm 447 moves together with the rotation of the synchronous wheel 446, and, under the action of the lever arm 445, the top of the adjustment arm 447 drives the bottom end of the adjustment arm 447 to make a linear motion, so that the connecting shaft four reciprocates along the transverse hole, and the moving part 2 448 reciprocates on the beam 421 synchronously with the connecting shaft four, and then the linear motion distance of the moving part 2 448 is used to reflect the amplitude of the lateral vibration, and the vibration amplitude generated is amplified by the displacement motion, so that the detection personnel can find problems more clearly and significantly.
