Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: a protective hot oil pump, including a base 1, a pump body, and a drive motor 13. The pump body and the drive motor 13 are both arranged on the base 1.

[0029] The pump body includes a pump housing 10. One side of the pump housing 10 is sealed by a detachable end cover 19. The edge of the end cover 19 is fastened to the pump housing 10 by bolts. A bearing seat 8 is provided at the center of the end cover 19. A pump shaft (not shown in the figure) is rotatably arranged in the bearing seat 8. The pump shaft extends into the pump housing 10 and is connected to an impeller (not shown in the figure). The other end of the pump shaft is connected to the rotating shaft of the drive motor 13. The drive motor 13 can drive the impeller to rotate in the pump housing 10. An inlet 11 is provided on the side of the pump housing 10 away from the pump shaft, an outlet 9 is provided at the top, and a support 12 is provided at the bottom of the pump housing 10. The support 12 is connected to the base 1, and the two are connected by bolts.

[0030] Immediately afterwards, an exhaust fan is installed on the rotating shaft of the drive motor 13 in this application. The specific structure of the exhaust fan includes a mounting disc 15, which is coaxially fixed on the rotating shaft of the drive motor 13. A plurality of fan blades 16 are arranged at the edge of the mounting disc 15. The roots of the fan blades 16 are fastened to the edge of the mounting disc by bolts, so that each fan blade can rotate with the rotation of the drive motor;

[0031] The drive motor 13 is located inside the protective housing 17. The protective housing 17 is arranged on the base 1, and a protective air hood 18 is coaxially connected to one end of the protective housing 17 close to the pump body. That is, the exhaust fan is placed inside the protective air hood 18. The protective air hood 18 is coaxially arranged with the exhaust fan and there is no contact between them. The rotating shaft of the drive motor 13 is completely located inside the protective air hood 18. One end of the protective housing 17 far from the pump body communicates with the outside, and there is also a gap between the drive motor 13 and the protective air hood 18, which facilitates the circulation of air around the drive motor 13.

[0032] Specifically, when the present utility model is in use, when the drive motor 13 rotates, it drives the impeller to rotate. At this time, the fan blades 16 also rotate with the motor. When the fan blades 16 rotate, they can drive the air inside the protective air hood 18 to be quickly discharged outward. The air located inside the protective housing 17 is quickly sucked into the protective air hood 18, so that the outside air quickly flows into the protective housing 17 and flows past the drive motor, quickly cooling the drive motor.

[0033] While cooling the drive motor, the provided protective air hood 18 also covers the rotating shaft of the drive motor 13 therein, preventing the rotating shaft from touching external objects during rotation and avoiding the occurrence of danger.

[0034] The present application also makes further improvements to the protective housing 17. That is, the protective housing 17 includes a support housing 5 arranged on the base 1. The drive motor 13 is located inside the support housing 5 and there is a gap between them. A sealing cover 6 is arranged above the support housing 5. The sealing cover 6 covers and seals the top of the drive motor 13. The sealing cover 6 is of an arc-shaped structure. One side of the sealing cover 6 is rotatably connected to one side of the top of the support housing 5, and the other side of the sealing cover 6 is connected to the top of the support housing 5 through a lock. Because the motor needs to be maintained, repaired, wired, etc. during operation, as Figure 2 shown, a wire passing port 4 is also arranged on one side of the support housing 5. The cable connected to the motor can enter the support housing 5 from the wire passing port 4 and be wired to the control box of the motor. After the wiring is completed, the sealing cover 6 can be closed, and at this time the drive motor can be protected.

[0035] At the same time, the present application also makes further improvements to the protective air hood 18. That is, the protective air hood 18 includes a first arc-shaped cover 2 and a second arc-shaped cover 7. As Figure 1 and Figure 2 shown, one end of the first arc-shaped cover 2 is connected to the support housing 5. The second arc-shaped cover 7 is installed above the first arc-shaped cover 2. The second arc-shaped cover 7 and the first arc-shaped cover 2 form a cylindrical air duct. The second arc-shaped cover 7 and the first arc-shaped cover 2 are detachable. Connecting edges 3 are arranged at the edges of the second arc-shaped cover 7 and the first arc-shaped cover 2, and the connecting edges 3 are fastened by bolts, which is convenient to open the second arc-shaped cover 7 to completely expose the fan blades 16. As Figure 6As shown, it is the state after the second arc-shaped cover 7 and the sealing cover 6 are opened.

[0036] It should be noted that, as Figure 1 and Figure 3 shown, when the sealing cover 6 is covered, there is a clearance fit between the sealing cover 6 and the second arc-shaped cover 7. To avoid air leakage between the two, rubber gaskets can be provided at the edges of the two to play a sealing role.

[0037] Furthermore, protective nets are provided at one end of the first arc-shaped cover 2 and the second arc-shaped cover 7 away from the protective housing 17, and protective nets (not shown in the figure) are provided at one end of the support housing 5 and the sealing cover 6 away from the pump body. This can prevent foreign objects from entering the protective housing 17 and the protective air cover 18 along with the airflow.

[0038] Based on the above embodiments, it can be further optimized. To further increase the strength of the support housing 5 and the sealing cover 6, as Figure 3 shown, the support housing 5 and the sealing cover 6 are connected by a reinforcing rod 20 on the side away from the pump body.

[0039] Based on the above embodiments, it can be further optimized. As Figure 2 shown, a bracket 14 is provided at the bottom of the bearing housing 8, and the bottom of the bracket 14 is connected to the base 1. This can support the bearing housing 8 and make the pump shaft more stable.
