Description

Technical Field

[0001] This utility model relates to the field of circulating pump technology, and in particular to a high-sealing split-type waste acid circulating pump. Background Technology

[0002] The main function of a circulating pump is to provide power for the circulation of liquids, ensuring that water can circulate in the system according to the designed flow rate. Specifically, a circulating pump can lift liquids to higher places and increase the velocity of fluids in the pipes.

[0003] The existing circulating pump impeller and shaft sleeve are integrated. After long-term high-temperature operation, the outer material of the shaft sleeve wears down slowly. Under high-speed operation, acid leakage slowly begins, corroding the mechanical seal. After each acid leakage, pump disassembly and repair require replacement of the impeller, mechanical seal, water seal, retaining ring, and bearing. Furthermore, when installing the lock nut between the impeller shaft sleeve and the water seal, the outer ring of the water seal may protrude or roll inward, causing leakage in the test pump. This results in problems such as a high number of pump disassembly and assembly operations per repair and a long maintenance time.

[0004] To address the existing problems of existing circulating pumps where the impeller and shaft sleeve are integrated, the outer material of the shaft sleeve gradually wears down during long-term high-temperature operation, leading to acid leakage and corrosion of the mechanical seal under high-speed operation, a circulating pump with a separate impeller and shaft sleeve is designed to overcome these issues. Utility Model Content

[0005] To overcome the problem that existing circulating pumps have an integrated impeller and shaft sleeve, which, after prolonged high-temperature operation, cause the outer material of the shaft sleeve to wear slowly, leading to acid leakage and corrosion of the mechanical seal under high-speed operation.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 - Figure 8 This utility model provides an embodiment of a high-sealing split-type waste acid circulation pump, including a pump body 1, an inlet 2, an outlet 3, a motor 4, an impeller 11, and a clamping block 15. The pump body 1 has an inlet 2 at its upper end and an outlet 3 on one side. The motor 4 is fixedly installed on one side of the pump body 1. The impeller 11 is rotatably arranged inside the pump body 1. The outer shell surface of the pump body 1 has a clamping block 15, which is used to fix and limit the outer shell connecting parts of the pump body 1. The surface of the impeller 11 has a sealing component for sealing, and the surface of the clamping block 15 has a fastening component for fastening the clamping block 15. The sealing component of this high-sealing split-type waste acid circulation pump greatly reduces the problem of leakage due to wear, thereby extending the service life of the circulation pump. The fastening component has a self-locking effect, and during the use of the circulation pump, the fastening component will not loosen due to the vibration of the circulation pump motor 4. Compared with the existing bolt-fixed connection method, the installation is more convenient and will not loosen.

[0025] Please see Figure 1 - Figure 4In this embodiment, a thrust bearing 5 is fixedly installed inside the pump body 1. A bearing cap 6 is provided on one side of the thrust bearing 5. A main shaft 7 is rotatably installed at the end of the thrust bearing 5. The sealing assembly includes a bushing 8, which is fixedly installed at one end of the main shaft 7. A water seal 9 is provided inside the pump body 1. One end of the main shaft 7 passes through the water seal 9. A mechanical seal 10 is provided inside the bushing 8. A back cap 12 is provided on one side of the impeller 11. An internal thread 13 is provided on the other side of the impeller 11. A hexagonal screw hole is provided on the surface of the back cap 12. The internal thread 13 on the other side of the impeller 11 is threadedly connected to one end of the main shaft 7.

[0026] Please see Figure 5 - Figure 8 In this embodiment, the fastening assembly includes an anti-slip handle 17, a worm gear 18 fixedly connected to one side of the anti-slip handle 17, a bearing seat 19 rotatably connected to one end of the worm gear 18, a worm wheel 20 meshing with the lower part of the worm gear 18, a lock nut 21 fixedly connected inside the worm wheel 20, a positioning rod 22 threadedly connected to the end of the lock nut 21, a positioning head 23 fixedly connected to one end of the positioning rod 22, a locking block 24 provided on one side of the positioning head 23, a bearing seat 25 rotatably connected to one side of the lock nut 21, and a clamping block 15. A side housing 16 is fixedly connected to one side of the pump body 1. A bearing seat 19 is fixedly connected to the inner wall of the side housing 16. A bearing seat 25 is fixedly installed on the inner wall of one side of the side housing 16. One end of the worm gear 18 passes through the side housing 16. A groove is provided on one side of the clamping block 15. A positioning hole 14 is provided on the outer surface of the pump body 1. The groove on the surface of the clamping block 15 is adapted to the clamping block 24. The clamping block 15 is set at the positioning hole 14. A hole is provided on the surface of the clamping block 15. The positioning rod 22 passes through the positioning hole 14 and the surface hole of the clamping block 15.

[0027] When in use, waste acid enters the pump body 1 through the inlet 2 on one side of the pump body 1. The motor 4 drives the impeller 11 to rotate through the main shaft 7, so that the waste acid flows into the outlet 3 at the upper end of the pump body 1, thus realizing circulation.

[0028] The bushing 8 is fixedly connected to one end of the main shaft 7 and is designed to be separate from the impeller 11. This way, when the bushing 8 rotates and wears, leakage will not cause corrosion of the mechanical seal 10. The impeller 11 is connected to one end of the main shaft 7 by an internal thread 13. This way, when installing the impeller 11, the water seal 9 will not be affected and will not be rolled inward or protruded. When installing the impeller 11, use a hex wrench to install the impeller 11 on one end of the main shaft 7 through the back cap 12.

[0029] The bearing 5 is rotatably connected to the spindle 7, and the bearing cap 6 is used to support the bearing 5, so that the spindle 7 can be more stable when rotating at the bearing 5.

[0030] When installing the outer casing of pump body 1, align the positioning hole 14 of the outer casing of pump body 1, then place the clamping block 15 at the positioning hole 14 and align the surface hole of the clamping block 15 with the positioning hole 14. Then, pass the positioning rod 22 through the positioning hole 14 and the surface hole of the clamping block 15, so that the locking block 24 on one side of the positioning head 23 matches the groove on the surface of the clamping block 15. Then, turn the anti-slip handle 17, and the anti-slip handle 17 drives the worm gear 18 to rotate at bearing seat 19. The worm wheel 20, which meshes with the worm gear 18, drives the lock nut 21 to rotate at bearing seat 25. The lock nut 21 is threaded to one end. During the rotation of the lock nut 21, the positioning head 23 at one end of the positioning rod 22 further clamps the clamping block 15. The positioning rod 22 is used to connect the outer casing of pump body 1, the clamping block 15 is used to secure the stability of the connection, and the side shell 16 is used to protect the fastening components from external environmental corrosion.

[0031] The worm gear 18 and worm wheel 20 have a self-locking effect, which ensures that the lock nut 21 will not loosen during the use of the pump body 1.

[0032] Through the above steps, the sealing component of this sealed split-type waste acid circulation pump adopts a design that separates the bushing 8 from the impeller 11. In this way, when the bushing 8 rotates and wears, leakage will not cause corrosion of the mechanical seal 10. The impeller 11 is connected to one end of the main shaft 7 by an internal thread 13. In this way, when installing the impeller 11, the water seal 9 will not be affected and will not be rolled inward or protruded. The fastening component has a self-locking effect. During the use of the circulation pump, the fastening component will not loosen due to the vibration of the circulation pump motor 4. Compared with the existing bolt fixing connection method, the installation is more convenient and will not loosen.
