[0002] When the magnetic pump transports some media that are easy to crystallize under normal temperature conditions, it usually uses an insulation jacket structure with an insulation cavity such as a pump body, a pump cover, and a connecting frame, and injects external insulation media into the insulation cavity to insulate the magnetic pump medium.

[0003] The prior art sets an insulation jacket on the outer circle of the pump body, pump cover, connecting frame, etc. of the magnetic pump, but it can only dissipate heat indirectly through heat conduction of the external heating medium, and insulates the inner cavity of the outer magnetic rotor, inner magnetic rotor, isolation sleeve, isolation sleeve, etc., which consumes a lot of energy, has low efficiency, and requires a large installation space.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 , Figure 2 The utility model provides a technical solution: a self-heating heat preservation circulation structure magnetic pump, including an isolation sleeve, a liquid inlet device 3, a pump body 4, a pump cover 5, a shaft system 6 and a bearing box device 7.

[0021] One end of the pump body 4 is connected to one side of the pump cover 5. The other side of the pump cover 5 is connected to the isolation sleeve. The shaft system 6 is arranged inside the isolation sleeve. The bearing box device 7 is arranged outside the isolation sleeve.

[0022] The isolation sleeve comprises an inner isolation sleeve 1 and an outer isolation sleeve 2. An isolation sleeve heat preservation cavity is formed between the inner isolation sleeve 1 and the outer isolation sleeve 2. The liquid inlet device 3 is connected to the isolation sleeve heat preservation cavity.

[0023] The utility model adds an isolation sleeve to the original standard magnetic pump structure to form a double isolation sleeve structure. That is, the inner isolation sleeve 1 and the outer isolation sleeve 2 in this application. The inner isolation sleeve 1 and the outer isolation sleeve 2 form a cavity containing a thermal insulation medium, and a liquid inlet device 3 is added through a pipeline. The liquid inlet device 3 is filled with a thermal insulation medium, and the thermal insulation medium enters and fills the thermal insulation cavity of the isolation sleeve through the pressure relationship, and the thermal insulation medium is in a balanced state. The inner isolation sleeve 1 and the outer isolation sleeve 2 generate heat by cutting the magnetic flux lines formed by the inner and outer magnetic rotors to heat and insulate the medium in the thermal insulation cavity of the isolation sleeve formed by themselves, thereby insulating the magnetic pump. The heat generated by cutting the magnetic flux lines itself achieves the thermal insulation effect and reduces the unlimited consumption of external heat energy by the circulating thermal insulation medium.

[0024] Furthermore, an inner magnetic rotor is arranged in the shaft system 6. An outer magnetic rotor is arranged in the bearing box device 7. The isolation sleeve is arranged between the inner magnetic rotor and the outer magnetic rotor.

[0025] Furthermore, it also includes a pipeline structure 8. The pipeline structure 8 includes a plurality of pipelines. The liquid inlet device 3 is connected to one end of the insulation cavity of the isolation sleeve through a pipeline. A pump insulation cavity is provided in the pump body 4. The other end of the insulation cavity of the isolation sleeve is connected to the pump insulation cavity through a pipeline.

[0026] Furthermore, the pipeline structure 8 also includes a plurality of pipeline connection sections. The pipelines are connected to each other through the pipeline connection sections. The multi-section pipeline connection allows the entire pipeline structure 8 to be flexibly disassembled and replaced. After long-term use, pipelines are prone to blockage or damage. The multiple pipelines are connected through pipeline connection sections, so that damaged or blocked pipelines can be replaced separately.

[0027] Furthermore, the inner isolation sleeve 1 and the outer isolation sleeve 2 are detachably connected, which can facilitate subsequent maintenance by the staff.

[0028] Furthermore, the liquid inlet device 3 is a funnel device. The smaller tubular portion at the mouth of the funnel can have different lengths. In the utility model, the liquid inlet device 3 is a funnel device, and the funnel is provided with a controllable valve at the mouth, so that the operator can control the speed of the fluid inflow.

[0029] Working principle:

[0030] The pump body 4 and the pump cover 5 are both provided with insulation cavities. The liquid inlet device 3 is inserted into the insulation cavity of the insulation sleeve formed by the inner isolation sleeve 1 and the outer isolation sleeve 2 through the pipeline structure 8. The medium in the insulation cavity of the isolation sleeve then enters the insulation cavity of the pump cover 5 and the pump body 4 through the pipeline structure 8 to insulate the magnetic pump. The insulation medium is heated and insulated in the insulation cavity formed by the double isolation sleeves. The outer isolation sleeve 1 and the outer isolation sleeve 2 generate heat by cutting the magnetic flux lines formed by the inner and outer magnetic rotors to heat and insulate the medium in the insulation cavity of the isolation sleeve formed by themselves.
