Description

Technical Field

[0001] The utility model relates to the technical field of thermal oil electric filters, in particular to a thermal oil electric heating self-circulating filter. Background Art

[0002] At present, the thermal oil electric heating self-circulating filter is a system used to heat and transfer heat to thermal oil in industrial equipment. This system transfers heat from the heater to the heating equipment by circulating the thermal oil to achieve heating of process materials or media.

[0003] The existing thermal oil electric filter will have the problem of poor heating during use. This is because for the convenience of installation, the heating rod is placed at the bottom to allow the heat to slowly conduct upwards. The preheating time is long. If there is not sufficient preheating, the oil temperature below will be high and the oil temperature above will be low. When the filter just starts working, the thermal oil is heated unevenly, and it is difficult to accurately control the oil temperature, which will cause the pressure of the filter to become high when used and incomplete filtration. Therefore, it is necessary to design a thermal oil electric self-circulating heating filter that can evenly heat the heat medium inside the thermal oil electric filter. Utility Model Content

[0004] In order to solve the technical problem of uneven heating of the internal heat medium of the thermal oil electric filter during the heating process, the utility model provides a thermal oil electric heating self-circulating filter.

[0006] Through the above technical solution, when the filter body heats the internal heat medium, the circulation component allows the heat medium to flow and circulate, and the preheating component allows the pipeline of the circulation component to preheat, so that the heat medium can be heated quickly and evenly.

[0007] As a further improvement of the above solution, one end of the heat medium inlet pipe and the heat medium outlet pipe are both connected to the inside of the filter body for circulating the heat medium inside the filter body.

[0008] Through the above technical solution, the heat medium inside the filter body can flow and circulate through the heat medium outlet pipe and the heat medium inlet pipe.

[0009] As a further improvement of the above solution, control valves are installed on both the heat medium inlet pipe and the heat medium outlet pipe.

[0010] Through the above technical solution, when heat medium circulation is not required, the pipeline can be closed using a control valve.

[0011] As a further improvement of the above solution, the preheating assembly includes a plurality of insulation sleeves slidably mounted on the heat medium inlet pipe and the heat medium outlet pipe and a plurality of heating rods arranged inside each insulation sleeve.

[0012] Through the above technical solution, the heating rod and the insulation sleeve can preheat and insulate the pipeline, and assist the circulation heating of the heat medium.

[0013] As a further improvement of the above scheme, the fixing assembly includes a fixing half ring arranged on one side of the insulation sleeve and a fixing belt fixedly installed on one side of the fixing half ring, a limiting ring is fixedly installed on one side of the fixing half ring, and a fixing block is provided on one side of the limiting ring and fixedly installed with the fixing half ring.

[0014] Through the above technical solution, the fixing half ring cooperates with the fixing belt to tighten and fix the thermal insulation sleeve.

[0015] As a further improvement of the above solution, the fixing belt is provided with a plurality of fixing holes matched with the fixing blocks.

[0016] Through the above technical solution, multiple fixing holes can allow the fixing belt to be tightened.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model arranges a circulation component, a preheating component and a fixing component. When the filter body is heated by the heat medium, the fixing component is used to fix the preheating component on the circulation component, the preheating component is turned on to heat the circulation component, and the circulation component is started to circulate the heat medium inside the filter body. This arrangement can not only heat the heat medium inside the filter body evenly, but also allow the circulation component to be preheated first to accelerate the heating speed of the heat medium.
