[0032] The utility model is further described in conjunction with the following embodiments.

[0033] As shown in Figures 1-5, an oil diffusion pump fin-type armored heating component includes a heating ring 1, a heating tube compartment 2 is provided on the heating ring 1, the outside of the heating tube compartment 2 is welded to the heating ring 1 through an external terminal block 3 for sealing, a plurality of armored heating sleeves 4 are arranged around the inner wall of the heating ring 1, an electric heating tube 5 is movably installed inside the armored heating sleeve 4, a plurality of heat-conducting fins 6 are movably mounted on the armored heating sleeve 4, and auxiliary locking components 7 are movably installed on the plurality of heat-conducting fins 6.

[0034] The present application is used for heating an oil diffusion vacuum pump. First, the overall assembly is fixed by a heating ring 1 and installed inside the oil diffusion vacuum pump. Then, the electric heating tube 5 is installed through the inside of the heating tube bin 2. The heating tube bin 2 is welded and closed by an external terminal block 3. The electric heating tube 5 is installed inside an armored heating sleeve 4 to provide heat to the inside of the oil diffusion vacuum pump. The heat-conducting fins 6 of the movable set can diffuse the heat of the armored heating sleeve 4 to increase the heat dissipation area and improve the heating efficiency. A plurality of heat-conducting fins 6 are positioned by a combination of the armored heating sleeve 4 and an auxiliary locking assembly 7 to prevent tilting and rotation.

[0035] One end of the armored heating sleeve 4 is facing the center of the heating ring platform 1 and is closed, and the other end of the armored heating sleeve 4 is welded to the inner wall of the heating ring platform 1 and is connected to the heating tube warehouse 2. Several limit rings 8 are evenly installed on the armored heating sleeve 4, and the number of limit rings 8 corresponds to the heat-conducting fins 6.

[0036] The armored heating sleeve 4 is installed on the inner wall of the heating ring platform 1 and is connected with the heating tube warehouse 2, so that the electric heating tube 5 can be inserted from the heating tube warehouse 2 into the armored heating sleeve 4. The electric heating tube 5 can be quickly replaced in the armored heating sleeve 4. The limit ring 8 limits the position of the thermal fin 6 to prevent the thermal fin 6 from sliding together to reduce the heat dissipation area.

[0037] The heat-conducting fin 6 is provided with a sleeve through hole 9 and a positioning through hole 10. The interior of the sleeve through hole 9 moves through the armored heating sleeve 4, and the interior of the positioning through hole 10 moves through the auxiliary locking assembly 7. The auxiliary locking assembly 7 includes an auxiliary locking sleeve 71. The auxiliary locking sleeve 71 moves through a number of heat-conducting fins 6. Threaded sleeves 72 are inserted at both ends of the auxiliary locking sleeve 71. The internal spirals of the two threaded sleeves 72 pass through screws 73. Locking nuts 74 are spirally installed at both ends of the screw 73, and the locking nuts 74 fit with the threaded sleeves 72.

[0038] The heat-conducting fins 6 are sleeved on the outside of the armored heating sleeve 4 through the sleeve through hole 9, and are limited by the positioning through hole 10 and the auxiliary locking assembly 7 to prevent the heat-conducting fins 6 from tilting or rotating. The auxiliary locking assembly 7 passes through several heat-conducting fins 6 through the auxiliary locking sleeve 71, and then passes through the threaded sleeve 72 through the screw 73. The threaded sleeve 72 is inserted into the two ends of the auxiliary locking sleeve 71.

[0040] The bottom of the thermal fin 6 is attached to the inner bottom surface of the heating ring 1 to further stabilize the thermal fin 6. At the same time, the limiting ring 8 can prevent the thermal fin 6 from sliding toward the center of the heating ring 1. The side of the thermal fin 6 away from the center of the heating ring 1 is limited by the limiting ring 8 and the inner wall of the heating ring 1.

[0041] The area of ​​the heat conducting fin 6 gradually decreases from the end close to the inner wall of the heating ring platform 1 to the end far away from the inner wall of the heating ring platform 1 .

[0042] The area of ​​the heat-conducting fins 6 can accommodate the plurality of armored heating sleeves 4 installed in a ring array, thereby improving the efficiency of heat dissipation area utilization.

[0043] A plurality of heat conducting holes 11 are formed on the auxiliary locking sleeve 71 .

[0044] The heat-conducting hole 11 can reduce thermal expansion of the auxiliary locking sleeve 71 .

[0045] The utility model is fixedly installed by a heating ring platform 1 and a plurality of armored heating sleeves 4, and then an electric heating tube 5 is inserted from the inside of a heating tube bin 2 into the inside of the armored heating sleeve 4 for heating, and then heat is diffused through heat-conducting fins 6, thereby greatly reducing indirect energy loss of heating and improving the efficiency of the vacuum pump. At the same time, the electric heating tube 5 does not contact the inside of the diffusion pump, thereby avoiding the problem of exposure of high-voltage electric energy.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
