Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump technology, and in particular to a high-efficiency chemical raw material liquid conveying device. Background Technology

[0002] A centrifugal pump is a device that uses the centrifugal force generated by the high-speed rotation of an impeller to efficiently transport chemical raw materials and liquids. Its core components include the impeller, pump casing, and shaft seal. During operation, the motor drives the impeller to rotate, and the liquid is thrown from the center of the impeller to the edge under centrifugal force. Within the pump casing, kinetic energy is converted into pressure energy, forming a high-pressure liquid flow that is discharged. This device features stable flow rate, high transport efficiency, and compact structure, and is widely used in the chemical industry for long-distance or high-pressure transport of various corrosive and viscous liquids. However, the blade size of existing traditional centrifugal pumps is mostly fixed. When conveying chemical raw materials of different viscosities or corrosiveness, or when it is necessary to adjust the flow rate and head to meet production needs, the entire impeller must be replaced. It is impossible to achieve quick adaptation through on-site adjustment, resulting in low equipment versatility. Multiple specifications of impellers need to be stocked, which increases costs and management difficulty. In addition, chemical raw materials often contain impurities such as solid particles and suspended matter. Traditional equipment lacks efficient pre-filtration devices. After impurities enter the pump with the liquid, they will aggravate the wear and corrosion of impeller, pump casing and other components, shorten the equipment life, and may also block the flow channel, which will greatly affect the working efficiency. Therefore, we propose a high-efficiency chemical raw material liquid conveying device to solve the above problems. Utility Model Content

[0004] Specifically, a filter element housing is detachably installed on the inner side of the filter pipe, and a columnar stainless steel mesh filter element is fixedly installed on the inner side of the filter element housing, which facilitates preliminary filtration of materials and prevents damage to the internal structure of the centrifugal pump body.

[0005] Specifically, the impeller base has multiple guide grooves on the side near the feed head, and guide metal blocks are slidably installed on the inner side of each guide groove.

[0006] Specifically, a threaded sleeve is fixedly installed on the same side of the impeller base, and a threaded rod is threadedly connected to the inner side of the threaded sleeve. A linkage head is fixedly installed at one end of the threaded rod, so that the threaded rod can be moved by the linkage head.

[0007] Specifically, one end of the linkage head is provided with a cross groove, the outer side of the linkage head is provided with an annular groove, and a fixing ring is rotatably installed on the inner side of the annular groove, so that the sliding sleeve can be moved by the linkage head through the fixing ring.

[0008] Specifically, a sliding sleeve is fixedly installed on the outer side of the fixed ring, and multiple linkage bases are fixedly installed on the outer side of the sliding sleeve. Each of the multiple linkage bases has two linkage grooves on its top, and an alloy crank is rotatably installed on the inner side of each of the multiple linkage grooves.

[0009] Specifically, two of the multiple alloy cranks located on the same linkage base have one end hinged to the same extension base, and one end of each of the multiple extension bases is fixedly connected to a corresponding guide metal block, so as to guide the movement trajectory of the extension base through the guide metal block.

[0010] Specifically, blades are fixedly installed on one side of each of the multiple extension bases, which facilitates the adjustment of the blade position through the extension bases.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting the blades and extending the base, it can flexibly adapt to different working conditions without replacing the impeller. For chemical raw materials with different viscosities and corrosiveness, or for changes in flow rate and head, the length of the extended blades can be adjusted simply by rotating the linkage head, which greatly improves the versatility of the equipment, reduces the cost of storing multiple specifications of impellers, and reduces management complexity. Furthermore, by setting the columnar stainless steel mesh filter element, it can efficiently intercept solid particles, suspended matter, fibers and other impurities in the fluid, achieve media purification through physical sieving, extend the service life of the equipment, reduce the risk of sudden shutdown due to blockage, and greatly improve work efficiency.

[0014] Reference Figure 1-5 A high-efficiency chemical raw material liquid conveying device includes a centrifugal pump body 1, a housing 2 fixedly installed on one side of the centrifugal pump body 1, a drive motor on the centrifugal pump body 1, a pump shaft 7 fixedly installed at the output end of the drive motor, the pump shaft 7 extending into the housing 2, an impeller base 8 rotatably installed on the inner wall of one side of the housing 2, one end of the pump shaft 7 being fixedly connected to the impeller base 8; a feed head 3 fixedly installed on one side of the housing 2, one end of the feed head 3 being connected to a filter pipe 4 via a bolt flange.

[0015] In this embodiment, a filter element housing 5 is detachably installed on the inner side of the filter pipe 4, and a columnar stainless steel mesh filter element 6 is fixedly installed on the inner side of the filter element housing 5, which facilitates preliminary filtration of materials and prevents damage to the internal structure of the centrifugal pump body 1.

[0016] In this embodiment, the impeller base 8 is provided with multiple guide grooves on the side near the feed head 3, and guide metal blocks 17 are slidably installed on the inner side of each of the multiple guide grooves.

[0017] In this embodiment, a threaded sleeve 9 is fixedly installed on the same side of the impeller base 8, and a threaded rod 10 is threadedly connected to the inner side of the threaded sleeve 9. A linkage head 13 is fixedly installed at one end of the threaded rod 10, so that the threaded rod 10 can be moved by the linkage head 13.

[0018] In this embodiment, a cross groove is provided at one end of the linkage head 13, an annular groove is provided on the outer side of the linkage head 13, and a fixing ring 12 is rotatably installed on the inner side of the annular groove, so that the sliding sleeve 11 can be moved by the linkage head 13 through the fixing ring 12.

[0019] In this embodiment, a sliding sleeve 11 is fixedly installed on the outer side of the fixed ring 12, and multiple linkage bases 14 are fixedly installed on the outer side of the sliding sleeve 11. Each of the multiple linkage bases 14 has two linkage grooves on its top, and an alloy crank 15 is rotatably installed on the inner side of each of the multiple linkage grooves.

[0020] In this embodiment, two alloy cranks 15 located on the same linkage base 14 are hinged to the same extension base 16 at one end. One end of each extension base 16 is fixedly connected to a corresponding guide metal block 17, so as to guide the movement trajectory of the extension base 16 through the guide metal block 17.

[0021] In this embodiment, blades 18 are fixedly installed on one side of each of the multiple extension bases 16, so that the position of the blades 18 can be adjusted through the extension bases 16.

[0022] Working principle: When conveying different chemical raw material liquids, the effective length of the blade 18 in the flow channel can be changed to adapt to different flow rates, head requirements, or media characteristics. After the filter pipe 4 is disassembled, the linkage head 13 is rotated with a Phillips screwdriver. The linkage head 13 is fixedly connected to the threaded rod 10, and the threaded rod 10 is threadedly connected to the threaded sleeve 9. The threaded sleeve 9 is fixedly installed on the impeller base 8, and the impeller base 8 is fixedly connected to the pump shaft 7. In the stopped state, the drive motor installed on the centrifugal pump body 1 has a self-locking property, so the pump shaft 7, along with the impeller base 8 and the threaded sleeve 9, cannot rotate. At this time, the threaded rod 10 can only rotate axially along the internal thread of the threaded sleeve 9. The movement of the threaded rod 10 drives the sliding sleeve 11 to move through the linkage head 13 and the fixing ring 12. The movement of the sliding sleeve 11 drives multiple linkage bases 14 to move. Each of the multiple linkage bases 14 is equipped with two Multiple alloy cranks 15 are hinged to corresponding extension bases 16. One end of each extension base 16 is fixedly equipped with a guide metal block 17. Multiple guide grooves are opened on one side of the impeller base 8. Multiple guide metal blocks 17 are slidably installed inside the corresponding guide grooves. When the multiple extension bases 16 move, they are guided by the corresponding guide metal blocks 17. Therefore, the multiple extension bases 16 can only move radially. The movement of the multiple extension bases 16 drives the corresponding blades 18 to move, thereby adjusting the effective length of the blades 18 in the flow channel to adapt to different working conditions. After the blades 18 are adjusted, the operator connects the filter pipe 4 to the feed head 3 with a flange using bolts. When transporting chemical raw material liquid, the columnar stainless steel mesh filter element 6 can intercept solid particles, suspended matter, fibers and other impurities in the fluid through physical sieving principle to achieve media purification.

[0023] The technological advancements of this invention compared to existing technologies are as follows: it allows for flexible adaptation to different working conditions without the need to replace the impeller. For chemical raw materials of different viscosities and corrosiveness, or for changes in flow rate and head, the extension length of the blades 18 can be adjusted simply by rotating the linkage head 13, greatly improving the equipment's versatility, reducing the cost of storing multiple impeller specifications, and lowering management complexity. Furthermore, the columnar stainless steel mesh filter element 6 can efficiently intercept solid particles, suspended matter, fibers, and other impurities in the fluid, achieving media purification through physical sieving, extending the equipment's service life, reducing the risk of sudden shutdowns due to blockages, and greatly improving work efficiency.
