Description

Technical Field

[0001] The present invention relates to the technical field of chemical pumps, and specifically to a chemical pump with a lining assembly. Background Art

[0002] A chemical centrifugal pump refers to a centrifugal pump used in the chemical field. Compared with other types of pumps, it has the advantages of simple structure, low wear, stable operation, low noise, uniform water output, convenient adjustment, and high efficiency. Therefore, chemical centrifugal pumps have been widely used.

[0003] When there are operating problems with the pump body or the motor body and severe vibrations occur, at this time, the motor will transmit its own vibration force to the pump body, resulting in damage to the pump body and the shaft. On the contrary, when the pump body transmits its own vibration force to the motor, it will cause wear to the output shaft of the motor, and in severe cases, problems such as cracking will occur.

Both the first rack and the second rack are slidably fitted inside the Z-shaped cover, and a second sleeve strip is fixedly connected to the outside of the second rack.

[0014] Preferably, the separation mechanism includes a compensator. One end of the compensator is fixedly connected to the support shaft seat, the end of the compensator close to the support shaft seat is rotatably connected to the connecting shaft, and the end of the compensator away from the support shaft seat is fixedly connected to a pump housing. A gasket is arranged inside the pump housing. The central parts of both the pump housing and the gasket are rotatably connected to a pump shaft, and the inner end surface of the pump shaft is connected to the connecting shaft.

[0015] Preferably, one end of the pump shaft away from the connecting shaft is fixedly connected to an impeller, and the impeller is rotatably connected inside the pump housing. An inspection component is fixedly installed on the top of the pump housing. A blade is fixedly connected to the side of the impeller away from the gasket.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the expansion body is broken, the airbag will swell instantly and squeeze the compensation rod outwards. Then the compensation rod will stretch the spring with the inserted rod, causing the compensation rod to extend from the inside of the spline block, thereby preparing for the subsequent separation of the spline block and the sleeve disc.

[0021] 2. By separating the servo motor from the pump body in the separation mechanism, the servo motor is prevented from transmitting vibration to the separation mechanism, causing damage to the pump body and shaft. It also prevents the pump body from transmitting vibration to the servo motor, causing wear and cracking of the servo motor's output shaft.

[0022] 3. When the impeller does work on the liquid, the kinetic energy and static pressure energy of the liquid are increased, thereby achieving liquid pressurization. The pressurized liquid is collected in the pump casing at the pump outlet, and then transported to the required place through the extrusion pipeline. When the liquid is discharged from the pump, a low-pressure area will be formed at the center of the impeller, and new liquid will be sucked into the center of the impeller under the action of the pressure difference. This cycle repeats, and the centrifugal pump can continuously transport liquid.

[0023] 4. By moving the sleeve upward, the extrusion pipe originally covered by the sleeve is exposed. The extrusion pipe is transparent, so that the operator can directly observe the flow state, liquid level height, etc. of the material in the pipeline or container through the glass sight glass.

[0024] 5. After passing through trapezoidal block No. 1, it will pass over trapezoidal block No. 2 and continue to move upward along the vertical groove until the No. 1 perforation opened on the extrusion pipe coincides with the No. 2 perforation opened on the sleeve pipe. At this time, the sprayed liquid will flow out, thereby enabling the inspection personnel to detect the gushing water flow and determine whether the water flow fluctuation has changed too much.

Detailed implementation manners

[0040] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments. It should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1 to 14 , the present invention provides a technical solution: As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , it includes a drive mechanism 2, and this drive mechanism 2 is used for driving the pump body;

[0042] a separation mechanism 3, and this separation mechanism 3 is used for separating and conveying the liquid;

[0043] The drive mechanism 2 is connected to the separation mechanism 3, and support platforms 1 are fixedly installed at the bottoms of both the drive mechanism 2 and the separation mechanism 3.

[0044] Among them, the driving mechanism 2 includes a frame 21. The frame 21 is arranged on the top of the support table 1. A servo motor 22 is fixedly connected to the top of the frame 21. A sleeve disc 23 is fixedly connected to the outside of the output end of the servo motor 22. A spline block 25 is inserted into one side of the sleeve disc 23 away from the servo motor 22. The spline block 25 penetrates through the other side of the sleeve disc 23 and is fixedly connected with a protection component 24.

[0045] One end of the spline block 25 away from the sleeve disc 23 is fixedly connected with a single-port shaft 26. One end of the single-port shaft 26 close to the spline block 25 is fixedly connected with a return spring 27. One end of the return spring 27 away from the single-port shaft 26 is in extrusion fit with the sleeve disc 23. A slot 28 is opened at one end of the single-port shaft 26 away from the return spring 27. A connecting shaft 29 is slidably fitted inside the slot 28. One end of the connecting shaft 29 away from the slot 28 is fixedly connected with a support shaft seat 203. The bottom of the support shaft seat 203 is fixedly connected with the support table 1. An outer slot 20 is opened on the outside of the connecting shaft 29. A slider 201 is slidably fitted inside the outer slot 20. By starting the servo motor 22, the sleeve disc 23 connected to the outside of its output end will rotate forward. The inside of the sleeve disc 23 is sleeved with the spline block 25. Additionally, under the compression force of the spring 246, the external disc 245 connected to the other end thereof will drive the insertion rod 242 to move towards the spline block 25. One end of the insertion rod 242 is connected to the compensation rod 243. Finally, the compensation rod 243 will be inserted into the spline block 25 to realize the fastening connection between the spline block 25 and the sleeve disc 23. Therefore, the rotational force of the sleeve disc 23 will be transmitted to the spline block 25. The other end of the spline block 25 is connected to the single-port shaft 26. The other end of the single-port shaft 26 is connected to the slider 201 through a double-headed rod 202. At the same time, the slider 201 is slidably fitted on the outer slot 20 opened on the surface of the connecting shaft 29. The sliding of the slider 201 on the outer slot 20 is at a right angle to the rotation of the motor, so they do not affect each other. One side of the slider 201 away from the support shaft seat 203 is fixedly connected with a double-headed rod 202. One end of the double-headed rod 202 away from the slider 201 is fixedly connected with the single-port shaft 26. By the compensation rod 243 extending out from the spline block 25 and then under the tensile force of the return spring 27, the single-port shaft 26 connected to the other end of the spline block 25 will move away from the sleeve disc 23. The slot 28 opened at the other end of the single-port shaft 26 will be engaged with the connecting shaft 29. At the same time, the double-headed rod 202 connected to the other end of the single-port shaft 26 will drive the slider 201 to move outwards along the outer slot 20, so as to separate the servo motor 22 from the pump body in the separation mechanism 3, avoiding the servo motor 22 from continuing to transmit vibration to the separation mechanism 3, resulting in damage to the pump body and the shaft. At the same time, it also plays a role in preventing the pump body from continuing to transmit vibration to the servo motor 22, resulting in wear and breakage of the output shaft of the servo motor 22.

[0046] As Figure 6 , Figure 7 and Figure 8 shown, the protection component 24 includes a Y-shaped frame 241. The Y-shaped frame 241 is fixedly connected to the outer side of the bushing disc 23. A through rod 242 is inserted on the surface of the Y-shaped frame 241. One end of the through rod 242 is fixedly connected to a compensation rod 243. The end of the compensation rod 243 away from the through rod 242 is inserted into the inside of the spline block 25. An expansion body 244 is arranged inside the spline block 25. The expansion body 244 is in extrusion fit with the compensation rod 243. One end of the through rod 242 away from the compensation rod 243 is fixedly connected to an external connection disc 245. A spring 246 is fixedly connected to the side of the external connection disc 245 close to the through rod 242. The end of the spring 246 away from the external connection disc 245 is fixedly connected to the Y-shaped frame 241. A first sleeve strip 240 is arranged on the outer side of the external connection disc 245. One end of the first sleeve strip 240 away from the external connection disc 245 is fixedly connected to a first rack 249. Additionally, when the servo motor 22 or the pump body in the separation mechanism 3 gets stuck or vibrates excessively during operation, at this moment, the expansion body 244 arranged inside the spline block 25 will break due to vibration and the impact of the compensation rod 243. Additionally, the stuck phenomenon will also cause the servo motor 22 to vibrate violently. The expansion body 244 is a plastic hollow ball, and an airbag is filled inside it. Therefore, when the expansion body 244 breaks, the airbag will instantly bulge and extrude the compensation rod 243 outward. Immediately afterwards, the compensation rod 243 will drive the through rod 242 to stretch the spring 246, causing the compensation rod 243 to extend from the inside of the spline block 25, thereby playing a role in making preparations for the subsequent separation of the spline block 25 and the bushing disc 23.

[0047] One end of the Y-shaped bracket 241 away from the bushing disc 23 is fixedly connected with a Z-shaped cover 247. A gear 248 is rotatably connected to the central part inside the Z-shaped cover 247 through a rotating shaft. The outer side of the gear 248 is meshed and driven with a first rack 249. A second rack 2401 is meshed and driven on the side of the gear 248 away from the first rack 249. The first rack 249 and the second rack 2401 are both slidably fitted inside the Z-shaped cover 247. A second sleeve bar 2402 is fixedly connected to the outer side of the second rack 2401. The outer side of the external connection disc 245 is connected to the first rack 249 through a first sleeve bar 240. Therefore, when the expansion body 244 ruptures, the first rack 249 will move outward together with the external connection disc 245 and the insertion rod 242. The first rack 249 is meshed and driven with the gear 248, and at the same time, the other side of the gear 248 is meshed and driven with the second rack 2401. Therefore, the second rack 2401 will drive the second sleeve bar 2402 connected thereto to move outward. In addition, the second sleeve bar 2402 is connected to the external connection disc 245 at the other end of the spline block 25. Therefore, the above-mentioned function is achieved that when one of the two expansion bodies 244 in the spline block 25 ruptures, the external connection discs 245 at both ends will move outward synchronously together, and the two compensation rods 243 will both extend outward from the spline block 25.

[0048] Such as Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14As shown, the separation mechanism 3 includes a compensator 31. One end of the compensator 31 is fixedly connected to the support shaft seat 203. The end of the compensator 31 close to the support shaft seat 203 is rotatably connected to the connecting shaft 29. The end of the compensator 31 far from the support shaft seat 203 is fixedly connected to a pump housing 32. A gasket 33 is arranged inside the pump housing 32. The central parts of both the pump housing 32 and the gasket 33 are rotatably connected to a pump shaft 34. The inner end face of the pump shaft 34 is connected to the connecting shaft 29. One end of the pump shaft 34 far from the connecting shaft 29 is fixedly connected to an impeller 35. The impeller 35 is rotatably connected inside the pump housing 32. An inspection assembly 38 is fixedly installed on the top of the pump housing 32. One side of the impeller 35 far from the gasket 33 is fixedly connected to a blade 39. One end of the pump housing 32 far from the compensator 31 is fixedly connected to an external housing 36. One end of the external housing 36 far from the pump housing 32 is fixedly connected to a suction pipe 37. As the connecting shaft 29 rotates forward, the pump shaft 34 connected to the other end thereof will rotate forward, and drive the impeller 35 fixedly connected to the outside thereof to rotate together. Before the centrifugal pump starts, the inside of the pump housing 32 and the suction pipe 37 need to be filled with the liquid to be transported to prevent the occurrence of air binding phenomenon. When the pump shaft 34 drives the impeller 35 to rotate at a high speed, the blades 39 on the impeller 35 will drive the liquid to rotate together, so that the liquid obtains centrifugal force. Under the action of the centrifugal force, the liquid is thrown from the center of the impeller 35 to the edge of the impeller 35, and a low-pressure area is formed at the center of the impeller 35. There is a pressure difference between the suction liquid level and the center of the impeller 35. Under the action of this pressure difference, the liquid will continuously be sucked from the suction container through the suction pipe 37 to the center of the impeller 35. After the liquid enters the impeller 35, with the rotation of the impeller 35, the liquid is accelerated in the flow channel between the blades 39. The impeller 35 does work on the liquid, increasing both the kinetic energy and the static pressure energy of the liquid, thus realizing the pressurization of the liquid. The pressurized liquid converges at the outlet of the pump in the pump housing 32, and then is transported to the required place through the pressure pipe 381. After the liquid is discharged from the pump, a low-pressure area is formed again at the center of the impeller 35, and new liquid will be sucked into the center of the impeller 35 under the action of the pressure difference. In this way, the centrifugal pump can continuously transport the liquid.

[0049] The inspection component 38 includes a discharge pipe 381, which is fixedly connected to the top of the pump housing 32. An external connection disk 382 is fixedly connected to the outer side of the discharge pipe 381. A telescopic rod 383 is fixedly connected to the top of the external connection disk 382. The top end of the telescopic rod 383 is fixedly connected to a docking flange 384. A sleeve pipe 385 is fixedly connected to the central part of the bottom of the docking flange 384. The liquid discharged from the discharge pipe 381 will sequentially discharge outward along the sleeve pipe 385 and the docking flange 384. Among them, the docking flange 384 can be lifted upward, so that the telescopic rod 383 connected to its bottom will extend upward. In addition, the central part of the bottom of the docking flange 384 is connected to the sleeve pipe 385. Therefore, the sleeve pipe 385 will move upward accordingly. At this time, the discharge pipe 381 originally covered by the sleeve pipe 385 is exposed. The discharge pipe 381 is transparent, so that the operator can directly observe the flow state, liquid level height and other conditions of the materials in the pipeline or container through the glass sight glass.

[0050] The surface of the extrusion tube 381 is provided with a No. 1 perforation 3804, and the extrusion tube 381 is slidably adapted inside the sleeve tube 385. The surface of the sleeve tube 385 is respectively provided with a No. 2 perforation 3805 and a vertical groove 386. The interior of the vertical groove 386 is fixedly connected with a No. 1 trapezoidal block 387. The top of the No. 1 trapezoidal block 387 is extruded and adapted with a No. 2 trapezoidal block 388. The No. 2 trapezoidal block 388 is slidably adapted inside the vertical groove 386. The outer side of the telescopic rod 383 is fixedly connected with a rod ring 380. The rod ring The outer side of 380 is fixedly connected with a cross bar 3801, and the end of the cross bar 3801 away from the rod ring 380 is sleeved with a plug-in block 389, and the end of the plug-in block 389 away from the cross bar 3801 is fixedly connected to the second trapezoidal block 388, and the end of the plug-in block 389 away from the second trapezoidal block 388 is fixedly connected with the second magnetic block 3803, and the end of the second magnetic block 3803 away from the plug-in block 389 is provided with a first magnetic block 3802, and the first magnetic block 3802 is fixedly connected to the inside of the cross bar 3801. A vertical groove 386 is provided on the outer side of the sleeve 385, and the interior of the vertical groove 386 is fixedly connected with a No. 1 trapezoidal block 387 and slidably connected with a No. 2 trapezoidal block 388. If the sleeve 385 continues to move upward, the No. 1 trapezoidal block 387 will squeeze and block the No. 2 trapezoidal block 388, and the operator will be reminded that the end of the first stage of operation has been reached. If the operator still lifts the sleeve 385 upward, the No. 2 trapezoidal block 388 squeezed by the No. 1 trapezoidal block 387 will be inserted into the interior of the cross bar 3801 with the plug-in block 389, and the No. 2 magnetic block 3803 fixedly connected to the other end of the plug-in block 389 will approach the No. 1 magnetic block 3802, and the repulsive force is maintained between the two magnetic blocks to reset the plug-in block 389 and the No. 2 trapezoidal block 388. Then the No. 1 trapezoidal block 387 will pass over the No. 2 trapezoidal block 388 and continue to move upward along the vertical groove 386 until the No. 1 perforation 3804 respectively provided on the extrusion tube 381 coincides with the No. 2 perforation 3805 provided on the sleeve tube 385. At this time, the liquid will spray outward, thereby enabling the inspector to detect the outflowing water flow and determine whether the water flow fluctuation has changed too much.

[0051] When the present invention is in use: First, start the servo motor 22, so that the sleeve disc 23 connected to the outside of its output end will rotate forward. The inside of the sleeve disc 23 is sleeved with the spline block 25. Additionally, under the compression force of the spring 246, the external disc 245 connected to the other end thereof will drive the insertion rod 242 to move towards the spline block 25. The other end of the insertion rod 242 is connected to the compensation rod 243. Finally, the compensation rod 243 will be inserted into the inside of the spline block 25 to achieve the fastening connection between the spline block 25 and the sleeve disc 23. Therefore, the rotational force of the sleeve disc 23 will be transmitted to the spline block 25. The other end of the spline block 25 is connected to the single-port shaft 26, and the other end of the single-port shaft 26 is connected to the slider 201 through the double-headed rod 202. At the same time, the slider 201 is slidably adapted to the outer groove 20 opened on the surface of the connecting shaft 29. The sliding of the slider 201 on the outer groove 20 is at a right angle to the rotation of the motor, so they do not affect each other.

[0052] With the forward rotation of the connecting shaft 29, the pump shaft 34 connected to the other end thereof will rotate forward, and drive the impeller 35 fixedly connected to the outside thereof to rotate together. Before starting the centrifugal pump, it is necessary to first fill the inside of the pump casing 32 and the suction pipe 37 with the liquid to be transported to prevent the occurrence of air binding. When the pump shaft 34 drives the impeller 35 to rotate at a high speed, the blades 39 on the impeller 35 will drive the liquid to rotate together, so that the liquid obtains centrifugal force. Under the action of the centrifugal force, the liquid is thrown from the center of the impeller 35 to the edge of the impeller 35, and a low-pressure area is formed at the center of the impeller 35. There is a pressure difference between the suction liquid level and the center of the impeller 35. Under the action of this pressure difference, the liquid will continuously be sucked from the suction container through the suction pipe 37 to the center of the impeller 35. After the liquid enters the impeller 35, with the rotation of the impeller 35, the liquid is accelerated in the flow path between the blades 39. The impeller 35 does work on the liquid, increasing both the kinetic energy and the static pressure energy of the liquid, thereby realizing the pressurization of the liquid. The pressurized liquid gathers at the outlet of the pump in the pump casing 32, and then is transported to the required place through the pressure pipe 381. When the liquid is discharged from the pump, a low-pressure area will be formed again at the center of the impeller 35, and new liquid will be sucked into the center of the impeller 35 under the action of the pressure difference. In this way, the centrifugal pump can continuously transport the liquid.
