Description

Technical Field

[0001] The invention relates to the technical field of chemical pumps, and more specifically to a high temperature resistant, wear resistant and corrosion resistant chemical pump. Background Art

[0002] A chemical pump is a pump used in the chemical production process. It converts the mechanical energy of the prime mover (such as an internal combustion engine, an electric motor, etc.) into static pressure energy and kinetic energy to achieve the function of conveying the medium. A chemical pump is usually composed of a pump body, a pump impeller, bearings, seals, etc. Its key components such as the pump body and seals are made of special materials to ensure stable operation in high temperature and corrosive environments, making the chemical pump play an important role in the fields of petrochemicals, pharmaceuticals, food, and environmental protection. Its excellent high temperature resistance, corrosion resistance, and wear resistance ensure its stable operation under extreme working conditions.

[0003] Existing chemical pumps can be mainly divided into centrifugal pumps, volumetric pumps and other types of pumps. Centrifugal pumps suck liquid into the pump through centrifugal force, and then push the liquid out of the pump body through the rotation of the rotor. They are characterized by large flow and stable pressure and are suitable for conveying clean water, wastewater, oil and some moderately corrosive liquids. Existing centrifugal pumps mainly drive the impeller to rotate to generate centrifugal force to suck liquid from the inlet pipe into the pump, and then push the liquid out of the outlet pipe from the pump body through the rotation of the impeller. However, when the chemical pump is shut down, the liquid in the outlet pipe will flow back into the pump body, and a large amount of liquid reflux will impact the impeller inside the pump body, which will increase the erosion of the impeller by the liquid, and the long-term erosion will affect the normal use of the impeller, greatly reducing the service life of the impeller in the chemical pump.

[0018] (1) This solution sets a blocking component. When the chemical pump stops, the liquid will flow back.

[0019] (2) This solution sets up a moving component, starts the air pump to suck external air into the air pump, and then blows the air into the air cavity, thereby pushing the baffle ring to move away from the liquid inlet pipe. The eight air cavities can stably push the baffle ring to move, thereby stably driving the connecting ring to close the through groove, thereby improving the use effect of the blocking component.

[0020] (3) This solution sets a control component, which will drive the boost impeller to rotate when the liquid refluxes, thereby starting the driving structure to drive the threaded rod to rotate, and then driving the sliding rod to drive the negative electrode electrical block to move in the direction of the positive electrode electrical block, so that the negative electrode electrical block and the positive electrode electrical block are in close contact, thereby starting the air pump to drive the baffle ring to close the through groove. After the liquid refluxes, the baffle ring can be driven in time to close the through groove, disconnecting the connection between the No. 2 straight pipe and the No. 1 straight pipe to prevent the liquid from continuing to reflux, thereby improving the use effect of the moving component, thereby further improving the use effect of the blocking component.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 11 A high temperature resistant, wear resistant and corrosion resistant chemical pump comprises a fixed base 1, a motor 2 is fixedly connected to one side of the upper surface of the fixed base 1, a pump body 3 is fixedly connected to the side of the upper surface of the fixed base 1 close to the motor 2, and the output end of the motor 2 penetrates into the pump body 3, a liquid inlet pipe 4 is fixedly connected to the side of the outer surface of the pump body 3 away from the motor 2, a liquid outlet pipe 10 is fixedly connected to one side of the outer circumferential surface of the pump body 3, and a blocking component 5 is arranged at one end of the liquid inlet pipe 4;

[0042] The blocking component 5 includes a No. 1 straight tube 51 fixed to one end of the liquid inlet pipe 4, and one end of the No. 1 straight tube 51 is closed, and one end of the outer circumferential surface of the liquid inlet pipe 4 is fixedly connected to a No. 2 straight tube 52, and the inner diameter of the No. 2 straight tube 52 is larger than the outer diameter of the No. 1 straight tube 51, and a retaining ring 54 is slidably connected between the outer circumferential surface of the No. 1 straight tube 51 and the inner circumferential surface of the No. 2 straight tube 52.

[0043] like Figure 2 , Figure 3 As shown, four evenly distributed through grooves 53 are opened on one side of the outer circular surface of the No. 1 straight tube 51, and four evenly distributed arc-shaped sliders 55 are fixedly connected to the inner circular surface of the retaining ring 54, and the four arc-shaped sliders 55 are distributed and slidably connected in the four through grooves 53, and the inner circular surfaces of the four arc-shaped sliders 55 are fixedly connected with a connecting ring 56.

[0044] like Figure 1As shown, a bearing box 12 is fixedly connected to one side of the outer surface of the pump body 3 close to the motor 2, and the output end of the motor 2 passes through the bearing box 12. A coupling 11 is arranged between the motor 2 and the bearing box 12, and the output end of the motor 2 passes through the coupling 11.

[0045] like Figure 1 As shown, a No. 2 bracket 13 is fixedly connected to the lower side of the outer surface of the pump body 3, and two evenly distributed No. 1 brackets 57 are fixedly connected to the lower surface of the No. 2 straight pipe 52, and the No. 1 bracket 57 and the No. 2 bracket 13 are both fixedly connected to the upper surface of the fixed base 1.

[0046] When in use, start the motor 2, and then drive the impeller inside the pump body 3 to rotate through the coupling 11 and the bearing box 12, so that the liquid is pumped into the pump body 3 through the liquid inlet pipe 4, and then the liquid in the pump body 3 is discharged through the liquid outlet pipe 10. However, when the chemical pump is shut down, the liquid will flow back into the pump body 3, impacting the impeller inside the pump body 3, increasing the erosion of the impeller by the liquid, and long-term erosion affects the normal use of the impeller, greatly reducing the service life of the impeller in the chemical pump. Therefore, a blocking component 5 is provided. When the chemical pump is started, the liquid first enters the No. 2 straight pipe 52, thereby pushing the retaining ring 54 to move toward the liquid inlet pipe 4, so that the through groove 53 is opened, thereby connecting the No. 2 straight pipe 52 and the No. 1 straight pipe 51, and then connecting the No. 2 straight pipe 52 and the liquid inlet pipe 4, so that the liquid enters the liquid inlet pipe 4 through the No. 1 straight pipe 51, ensuring the normal use of the chemical pump. When the chemical pump is shut down, the liquid will flow back through the liquid The reflux pushes the connecting ring 56 to move away from the liquid inlet pipe 4, thereby driving the arc-shaped slider 55 to move, and then driving the retaining ring 54 to move away from the liquid inlet pipe 4, so that the retaining ring 54 closes the through groove 53, thereby disconnecting the connection between the No. 2 straight pipe 52 and the No. 1 straight pipe 51, thereby preventing the liquid from continuing to flow back and impacting the impeller inside the pump body 3, reducing the erosion of the impeller by the liquid, thereby ensuring that the impeller can be used normally for a long time, greatly reducing the service life of the impeller in the chemical pump, and through the sliding connection between the arc-shaped slider 55 and the through groove 53, the moving range of the retaining ring 54 can be limited, and the retaining ring 54 can be effectively prevented from being separated from the position between the No. 2 straight pipe 52 and the No. 1 straight pipe 51, and through the No. 2 bracket 13 and the No. 1 bracket 57, the pump body 3 and the No. 2 straight pipe 52 are fixed to the fixed base 1, which can improve the stability of the pump body 3 and the No. 2 straight pipe 52, thereby improving the stability of the chemical pump.

[0047] like Figure 2 , Figure 4 , Figure 5As shown, a movable component 6 is arranged inside the retaining ring 54, and the movable component 6 includes eight evenly distributed air cavities 61 opened on the outer surface of the retaining ring 54 near the liquid inlet pipe 4, and the interiors of the eight air cavities 61 are all slidably connected with blowing pipes 62, and one end of the outer circumferential surface of the eight blowing pipes 62 is fixedly connected to a limiting block 68, and the other ends of the eight blowing pipes 62 pass through the No. 2 straight pipe 52 and are commonly fixedly connected to an annular pipe 63, and an air pump 65 is fixedly connected to the upper surface of the fixed base 1 below the annular pipe 63, a connecting pipe 64 is fixedly connected to one side of the upper surface of the air pump 65, and the upper end of the connecting pipe 64 is fixedly connected to the annular pipe 63, an intake pipe 66 is fixedly connected to one side of the outer surface of the air pump 65, and an outlet pipe 67 is fixedly connected to the side of the outer surface of the air pump 65 near the intake pipe 66.

[0048] In the above embodiment, the connecting ring 56 is pushed to move by the reflux of the liquid, thereby driving the baffle ring 54 to move and closing the through groove 53, so that the connection between the No. 2 straight pipe 52 and the No. 1 straight pipe 51 is disconnected to prevent the liquid from continuing to reflux. However, the connecting ring 56 cannot be accurately and stably driven to close the through groove 53 by the liquid, which reduces the use effect of the blocking component 5. Therefore, the moving component 6 is set to start the air pump 65 to suck the external air into the air pump 65 through the suction pipe 66, and then send the air into the annular pipe 63 through the connecting pipe 64. The air is then evenly distributed into the eight air blowing pipes 62 through the annular pipe 63, and finally the air is blown into the air cavity 61 through the air blowing pipe 62, thereby pushing the baffle ring 54 to move away from the liquid inlet pipe 4, and the eight air cavities 61 can stably push the baffle ring 54 to move, thereby stably driving the connecting ring 56 to close the through groove 53, thereby improving the use effect of the blocking component 5, and the air in the air cavity 61 can be discharged through the air outlet pipe 67, thereby facilitating the baffle ring 54 to move toward the direction of the liquid inlet pipe 4, so that the No. 2 straight pipe 52 is connected to the No. 1 straight pipe 51.

[0049] like Figure 4 , Figure 6 , Figure 7As shown, a control component 7 is provided on the outer circumferential surface of the liquid inlet pipe 4, and the control component 7 includes a thickened ring 71 fixedly connected to the outer circumferential surface of the liquid inlet pipe 4 near the side of the annular tube 63, and a control box 72 is fixedly connected to the lower side of the outer circumferential surface of the thickened ring 71, and a No. 1 slide groove 73 is provided on the lower side of the control box 72, and a slide rod 75 is slidably connected inside the No. 1 slide groove 73, and a threaded hole 76 is provided on one side of the outer surface of the slide rod 75, and a threaded rod 77 is rotatably connected to one side of the inner side of the No. 1 slide groove 73, and one end of the threaded rod 77 is threadedly connected to the threaded hole 76, and a negative electrical block 78 is fixedly connected to the side of the outer surface of the slide rod 75 away from the threaded hole 76, and a positive electrical block 79 is fixedly connected to the side of the inner wall of the No. 1 slide groove 73 away from the slide rod 75, and both the negative electrical block 78 and the positive electrical block 79 are electrically connected to the air pump 65, and a driving structure 74 is provided on one side of the No. 1 slide groove 73 in the control box 72.

[0050] like Figure 6 , Figure 7 As shown, the driving structure 74 includes a No. 1 driving cavity 741 opened on one side of the No. 1 slide groove 73 in the control box 72, the other end of the threaded rod 77 penetrates into the No. 1 driving cavity 741 and is fixedly connected to the No. 1 bevel gear 742, the lower end of the No. 1 driving cavity 741 is rotatably connected to the No. 2 bevel gear 743, and the No. 2 bevel gear 743 is meshed with the No. 1 bevel gear 742, the inner circular surface of the liquid inlet pipe 4 is located directly above the No. 1 driving cavity 741 and is fixedly connected to a cross-shaped mounting bracket 745, and the center position of the cross-shaped mounting bracket 745 is opened The No. 2 driving chamber 746, the upper surface of the No. 2 bevel gear 743 is fixedly connected to the No. 1 straight rod 747, and the upper end of the No. 1 straight rod 747 extends into the No. 2 driving chamber 746 and is fixedly connected to the No. 3 bevel gear 748, the No. 4 bevel gear 749 is rotatably connected to one side of the inner wall of the No. 2 driving chamber 746, and the No. 4 bevel gear 749 is meshed with the No. 3 bevel gear 748, the No. 2 straight rod 7410 is fixedly connected to one side of the outer surface of the No. 4 bevel gear 749, and the No. 2 straight rod 7410 passes through the cross-shaped mounting frame 745 and is fixedly connected to the boost impeller 7411.

[0051] In the above embodiment, air is blown into the air cavity 61 by the air pump 65, thereby pushing the retaining ring 54 to move away from the liquid inlet pipe 4, closing the through groove 53, and disconnecting the connection between the No. 2 straight pipe 52 and the No. 1 straight pipe 51, thereby preventing the liquid from continuing to flow back. However, the air pump 65 cannot be started in time after the liquid flows back, disconnecting the connection between the No. 2 straight pipe 52 and the No. 1 straight pipe 51, and preventing the liquid from continuing to flow back, thereby reducing the use effect of the moving component 6, and further reducing the use effect of the blocking component 5. Therefore, a control component 7 is provided, and when the liquid flows back, it will also drive the booster impeller 7411 to rotate, and the booster impeller 7411 rotates on the cross-shaped mounting frame 745, thereby improving the rotation stability of the booster impeller 7411, and then the No. 4 bevel gear 749 is driven to rotate synchronously in the No. 2 driving cavity 746 through the No. 2 straight rod 7410, thereby driving the No. 3 bevel gear 74 8 rotates, and then drives the second bevel gear 743 to rotate in the first driving chamber 741 through the first straight rod 747, thereby driving the first bevel gear 742 to rotate synchronously, and at the same time drives the threaded rod 77 to rotate, and through the threaded connection between the threaded rod 77 and the threaded hole 76, drives the sliding rod 75 to move in the first sliding groove 73, thereby driving the negative electrode electrical block 78 to move in the direction of the positive electrode electrical block 79, so that the negative electrode electrical block 78 and the positive electrode electrical block 79 are close to each other, and because the negative electrode electrical block 78 and the positive electrode electrical block 79 are both electrically connected to the air pump 65, the air pump 65 is started to drive the baffle ring 54 to close the through groove 53. After the liquid refluxes, the air pump 65 can be started in time to drive the baffle ring 54 to close the through groove 53, and the connection between the second straight pipe 52 and the first straight pipe 51 is disconnected to prevent the liquid from continuing to reflux, thereby improving the use effect of the moving component 6, thereby further improving the use effect of the blocking component 5.

[0054] In the above embodiment, the booster impeller 7411 is driven to rotate by the liquid reflux, thereby driving the threaded rod 77 to rotate, and then driving the slide bar 75 to drive the negative electrode electrical block 78 to move, so that the negative electrode electrical block 78 and the positive electrode electrical block 79 are close to each other, thereby starting the air pump 65 to drive the baffle ring 54 to close the through groove 53 to prevent the liquid from continuing to flow back. However, when the liquid flows in the forward direction, it will drive the booster impeller 7411 to rotate in the opposite direction, thereby driving the threaded rod 77 to rotate in the opposite direction, and then driving the slide bar 75 to drive the negative electrode electrical block 78 to move in the opposite direction, so that the negative electrode electrical block 78 and the positive electrode electrical block 79 are separated, thereby facilitating the reuse of the control component 7. The booster impeller 7411 rotates in the opposite direction, which can increase the flow rate of the liquid in the liquid inlet pipe 4. However, when the slide bar 75 moves to the far After leaving the positive electrode electrical block 79, the slide bar 75 cannot move further, so that the boost impeller 7411 cannot continue to rotate in the reverse direction. However, the positive flow of liquid in the liquid inlet pipe 4 will make the boost impeller 7411 have the potential energy for reverse rotation, but the boost impeller 7411 cannot rotate in the reverse direction, which makes the boost impeller 7411 prone to damage, affecting the normal use of the drive structure 74, thereby affecting the normal use of the control component 7. Therefore, a switching component 8 is provided. When the slide bar 75 moves to the side away from the positive electrode electrical block 79, the U-shaped slider 814 is pushed to move in the U-shaped slide groove 813 toward the direction of the first drive chamber 741, thereby driving the L-shaped slider 812 to move upward in the L-shaped slide groove 811, and at the same time driving the annular slider 810 to move. The second slider 83 is moved upward, thereby driving the second slider 83 to move upward, and at the same time driving the first latch tooth 86 to move upward, so that the first latch tooth 86 is separated from the second latch tooth 87, thereby separating the first slider 82 and the second slider 83, so that the boost impeller 7411 rotates to drive the fourth bevel gear 749 to rotate, thereby driving the third bevel gear 748 to rotate, and at the same time driving the third straight rod 85 to rotate, thereby driving the square straight rod 84 to rotate, and then driving the second slider 83 to rotate, and the outer surface of the second slider 83 is provided with an annular groove 89 which is rotatably connected with the annular slider 810, so that the second slider 83 is convenient for the rotation of the second slider 83, and the second slider 83 is separated from the first slider 82, so that the second slider 83 will not drive the first slider 82 to rotate, thereby driving the first straight rod 747 to rotate, so that the slider After the slide bar 75 moves to the side away from the positive electrical block 79, the threaded rod 77 cannot rotate, and the No. 1 bevel gear 742 cannot rotate, and the No. 2 bevel gear 743 and the No. 1 straight rod 747 cannot rotate. After the slide bar 75 moves to the side away from the positive electrical block 79, the No. 1 slider 82 and the No. 2 slider 83 can be separated at the same time, so that the boost impeller 7411 can continue to rotate, and will not drive the threaded rod 77 to rotate, thereby preventing the boost impeller 7411 from being damaged, ensuring the normal use of the drive structure 74, thereby ensuring the normal use of the control component 7, and when the slide bar 75 moves toward the direction of the positive electrical block 79, the No. 1 spring 88 drives the No. 2 slider 83 to move downward, so that the No. 1 clamping tooth 86 is engaged with the No. 2 clamping tooth 87.Thus, the second slider 83 can drive the first slider 82 to rotate, so that the control assembly 7 is convenient to use.

[0055] like Fig. 9 , Fig.10 , Fig.11 As shown, a limiting assembly 9 is arranged between the square straight rod 84 and the No. 1 slider 82, and the limiting assembly 9 includes a fixed block 91 fixedly connected to the lower end of the square straight rod 84, a rotating groove 92 is provided at the center position of the upper surface of the No. 1 slider 82, a rotating block 93 is fixedly connected to the lower surface of the fixed block 91, and the rotating block 93 is rotatably connected with the rotating groove 92, a ratchet groove 96 is provided on the inner circular surface of the rotating groove 92, and four evenly distributed No. 3 slide grooves 94 are provided on the outer circular surface of the rotating block 93, and the No. 3 sliders 97 are slidably connected inside the four No. 3 slide grooves 94, a ratchet tooth 95 is fixedly connected to the side of the outer surface of the No. 3 slider 97 close to the ratchet groove 96, and the ratchet tooth 95 is engaged with the ratchet groove 96, a groove 98 is provided on the side of the outer surface of the No. 3 slider 97 away from the ratchet tooth 95, and a No. 2 spring 99 is provided inside the groove 98.

[0056] In the above embodiment, after the slide bar 75 moves to the side away from the positive electrode electrical block 79, the switching component 8 drives the second slider 83 to move upward, so that the second slider 83 is separated from the first slider 82, so that the booster impeller 7411 cannot drive the threaded rod 77 to rotate in the opposite direction. However, when the liquid reflux drives the booster impeller 7411 to rotate, it cannot drive the threaded rod 77 to rotate, so that the control component 7 cannot be used normally. Therefore, a limiting component 9 is provided. When the booster impeller 7411 rotates, the third straight rod 85 is driven to drive the square straight rod 84 to rotate, thereby driving the rotating block 91 through the fixed block 91. 93 rotates, and then the No. 3 slider 97 is driven to move toward the ratchet groove 96 through the No. 2 spring 99 arranged in the groove 98, thereby driving the ratchet tooth 95 to move toward the ratchet groove 96, so that the ratchet tooth 95 is engaged with the ratchet groove 96, so that the rotation of the rotating block 93 can drive the No. 1 slider 82 to rotate at the same time, so that the rotation of the booster impeller 7411 can drive the threaded rod 77 to rotate, so that the control component 7 can be used normally, and when the booster impeller 7411 rotates in the reverse direction, because the ratchet tooth 95 is engaged with the ratchet groove 96, the rotating block 93 rotates in the reverse direction, and cannot drive the No. 1 slider 82 to rotate in the reverse direction.

[0057] Usage: Start the chemical pump. First, the liquid will enter the No. 2 straight pipe 52, thereby pushing the retaining ring 54 to move toward the liquid inlet pipe 4, opening the through groove 53, allowing the liquid to enter the No. 1 straight pipe 51, allowing the liquid to enter the liquid inlet pipe 4 through the No. 1 straight pipe 51, and finally pumped into the pump body 3, and then the liquid in the pump body 3 is discharged through the liquid outlet pipe 10. When the chemical pump stops, the liquid will flow back, thereby driving the boost impeller 7411 to rotate, thereby starting the driving structure 74, and at the same time driving the limiting component 9. The No. 1 slider 82 rotates, thereby driving the No. 2 bevel gear 743 to rotate through the No. 1 straight rod 747, and then driving the No. 1 bevel gear 742 to rotate, and at the same time driving the threaded rod 77 to rotate, thereby driving the slide rod 75 to drive the negative electrical block 78 to move toward the positive electrical block 79, so that the negative electrical block 78 and the positive electrical block 79 are close to each other, thereby starting the moving component 6, driving the retaining ring 54 to move to close the through groove 53, so that the connection between the No. 2 straight tube 52 and the No. 1 straight tube 51 is disconnected to prevent the liquid from continuing to flow back.
