Description

Technical Field

[0001] This utility model relates to the technical field of petrochemical process pumps, specifically a split-type high-temperature magnetic drive petrochemical process pump. Background Technology

[0002] Petroleum and chemical process pumps are high-end products, distinct from conventional chemical pumps. The petroleum and chemical industries are inherently hazardous, transporting media that are flammable, explosive, volatile, and toxic, requiring stringent temperature and corrosion resistance standards, as well as extremely stringent sealing and reliability requirements. Petroleum and chemical process pumps play a vital role in chemical plants; if a pump stops operating, the entire process ceases, resulting in significant economic losses for the production company. Conventional chemical pumps use mechanical seals, which are prone to leakage and do not meet the requirements of chemical processes. Magnetic drive petrochemical process pumps are fully sealed, leak-free pumps. Based on the working principle of permanent magnet couplings, they utilize magnetic fields to transmit torque without contact, achieving media transport in a sealed state. To address oil shortages, the country is vigorously developing the petrochemical industry, leading to rapid growth in demand for petrochemical process pumps. In many applications, the temperature of the transported media is often 300℃ or even higher. Traditional magnetic pumps, including the frictional heat from the sliding bearings on the pump shaft and the eddy current heat from the metal isolation sleeve, usually rely on the internal circulation of the pumped medium to cool and remove the heat. Obviously, this is feasible for mediums at normal temperature, but not for high-temperature media, because it will cause the magnets to demagnetize and the equipment to malfunction. Utility Model Content

[0003] The purpose of this invention is to provide a split-type high-temperature magnetic drive petrochemical process pump that cools the high-temperature medium pumped in, prevents the high-temperature medium from directly entering the pump body, and reduces the risk of demagnetization of the internal magnets and equipment malfunction.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The device includes a pump body and a cooling assembly detachably connected to the pump body. The cooling assembly includes a connecting pipe, which is installed at the input end of the pump body via a flange. An extension metal pipe is fixed to the end of the connecting pipe away from the pump body, and an inlet pipe is fixed to the end of the extension metal pipe away from the connecting pipe. A bracket is fixed inside the extension metal pipe, and a guide heat dissipation assembly is rotatably connected inside the bracket.

[0006] Furthermore, a heat sink is fixed to the side of the extended metal tube, and several heat sinks are provided and arranged along the circumference of the extended metal tube.

[0007] Using the above technical solution, when dissipating heat from a high-temperature medium, the surface temperature of the external extended metal tube rises, and the heat can be quickly dissipated through the heat sink on the side.

[0008] Furthermore, the guiding heat dissipation component includes a rotating shaft rotatably connected inside the bracket, and a tapered guide rod fixed outside the rotating shaft, the tapered guide rod being located inside the inlet tube.

[0009] Furthermore, a first bevel gear is fixed to the outside of the rotating shaft, the first bevel gear meshes with a second bevel gear, a drive shaft is fixed inside the second bevel gear, the drive shaft extends along the side of the inlet pipe, and a servo motor is fixed to the extended end.

[0010] Furthermore, the tapered guide rod has several ribs fixed on its side.

[0011] By adopting the above technical solution, several ribs are fixed on the side of the tapered guide rod, which can disperse the high-temperature medium and improve the subsequent heat dissipation efficiency.

[0012] Furthermore, a C-shaped rod is fixed to the side of the rotating shaft, and several C-shaped rods are provided along the circumference of the rotating shaft. The C-shaped rods are located inside the extended metal tube.

[0013] Using the above technical solution, after the high-temperature medium is introduced, the servo motor is turned on, which can drive the drive shaft to rotate. The rotation of the drive shaft can drive the second bevel gear to rotate, which in turn drives the first bevel gear to rotate. Then the rotating shaft starts to rotate, and the C-shaped rod on its side can provide a stirring function after rotation, stirring the high-temperature medium dispersed into the interior of the extended metal tube, further improving the heat dissipation efficiency of the high-temperature medium.

[0014] Furthermore, a heat insulation sleeve is provided on the outside of the connecting pipe.

[0015] By adopting the above technical solution, a heat insulation sleeve is installed on the outside of the connecting pipe to prevent the temperature of the extended metal pipe surface from entering the pump body and to ensure the normal operation of the pump body.

[0016] In summary, the beneficial technical effects of this utility model are as follows:

[0017] 1. A tapered guide rod and ribs are adopted. Several ribs are fixed on the side of the tapered guide rod, which can disperse the high-temperature medium and improve the subsequent heat dissipation efficiency.

[0018] 2. An inverted bar is used. After the high-temperature medium is introduced, the servo motor is turned on, which drives the drive shaft to rotate. The rotation of the drive shaft drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate. Then the rotating shaft starts to rotate. The inverted bar on its side provides a stirring function after rotation, stirring the high-temperature medium dispersed into the interior of the expansion metal tube, further improving the heat dissipation efficiency of the high-temperature medium.

[0019] 3. A heat insulation sleeve is adopted. A heat insulation sleeve is installed on the outside of the connecting pipe to prevent the temperature of the extended metal pipe surface from entering the pump body and ensure the normal operation of the pump body. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-2 This utility model provides a technical solution comprising a pump body 1 and a cooling assembly detachably connected to the pump body 1. The cooling assembly includes a connecting pipe 2, which is installed at the input end of the pump body 1 via a flange. An extension metal pipe 3 is fixed to the end of the connecting pipe 2 away from the pump body 1, and an inlet pipe 4 is fixed to the end of the extension metal pipe 3 away from the connecting pipe 2. A bracket 5 is fixed inside the extension metal pipe 3, and a guide heat dissipation assembly is rotatably connected inside the bracket 5. A plurality of heat dissipation fins 6 are fixed to the side of the extension metal pipe 3, arranged along the circumference of the extension metal pipe 3.

[0027] The heat dissipation guide includes a rotating shaft 7 rotatably connected inside the bracket 5, and a tapered guide rod 8 fixed outside the rotating shaft 7. The tapered guide rod 8 is located inside the inlet tube 4.

[0028] The high-temperature medium is connected to the inlet pipe 4. After entering the inlet pipe 4, the high-temperature medium enters the interior of the expansion metal pipe 3. During its introduction, it flows in along the side of the tapered guide rod 8. In this embodiment, several ribs 12 are fixed on the side of the tapered guide rod 8, which can disperse the high-temperature medium and improve the subsequent heat dissipation efficiency.

[0029] A first bevel gear 9 is fixed to the outside of the rotating shaft 7. The first bevel gear 9 meshes with a second bevel gear 10. A drive shaft is fixed inside the second bevel gear 10. The drive shaft extends along the side of the inlet pipe 4, and a servo motor 11 is fixed to the extended end.

[0030] A C-shaped rod 13 is fixed to the side of the rotating shaft 7. Several C-shaped rods 13 are provided along the circumference of the rotating shaft 7. The C-shaped rods 13 are located inside the extended metal tube 3.

[0031] After the high-temperature medium is introduced, the servo motor 11 is turned on, which can drive the drive shaft to rotate. The rotation of the drive shaft can drive the second bevel gear 10 to rotate, which in turn drives the first bevel gear 9 to rotate. Then the rotating shaft 7 starts to rotate, and the C-shaped rod 13 on its side can provide a stirring function after rotation, stirring the high-temperature medium dispersed into the interior of the extended metal tube 3, further improving the heat dissipation efficiency of the high-temperature medium.

[0032] When the high-temperature medium is dissipated, the surface temperature of the external extended metal tube 3 rises, and the heat can be quickly dissipated through the heat sink 6 on the side.

[0033] Meanwhile, a heat insulation sleeve 14 is fitted outside the connecting pipe 2 to prevent the temperature on the surface of the extended metal pipe 3 from entering the pump body 1, thus ensuring the normal operation of the pump body 1.

[0034] The working principle of this utility model is as follows: A detachable connecting pipe 2 and an extension metal pipe 3 are installed at the input end of the pump body 1. The extension metal pipe 3 is equipped with a rotating shaft 7 driven by a servo motor 11. The high-temperature medium pumped in is cooled by the dispersion guidance of the conical guide rod 8 and the stirring of the shaped rod 13, so as to avoid the high-temperature medium directly entering the pump body 1 and reduce the risk of demagnetization of the magnets inside the pump body 1 and the equipment malfunction.
