The liquid inlets of the pair of filter tanks are connected by a liquid inlet tee pipe, and the liquid outlets of the pair of filter tanks are connected by a liquid outlet tee pipe. Both the liquid inlet tee pipe and the liquid outlet tee pipe are provided with a three-way solenoid valve.

[0005] The filter tank has a ring of filter cartridge mounting protrusions inside, and a ring of rim at the top opening of the filter cartridge. The filter cartridge is movably inserted into the filter tank and pressed tightly by the cover.

[0006] The cover is fastened to the filter tank by a set of screws. A set of positioning rods is arranged in a ring at the bottom of the cover, and a compression spring is fitted on the positioning rod. The filter cartridge is pressed by a set of compression springs.

[0007] The filter cartridge is equipped with a handle at the top.

[0008] The two heating coils are connected in parallel via pipes.

[0009] The outer wall of the filter tank is equipped with a hollow heat-insulating jacket.

[0010] A pressure alarm is installed on the liquid inlet tee.

[0011] The advantages of this invention are: the two filter tanks are connected in parallel, with one filter tank working at a time, and can be quickly switched during maintenance and cleaning via a three-way solenoid valve without stopping the machine. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0014] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0015] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0016] In the description of the embodiments of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, if terms such as "first" or "second" appear in the description of this invention, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0017] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0018] As shown in the figure, this utility model includes a pair of filter tanks 20, a heating coil 21 is provided inside the filter tank 20, and a detachable filter cartridge 22 is provided inside the heating coil 21. The top of the filter tank 20 is provided with a cover 23 for pressing the filter cartridge 22. The liquid inlets of the pair of filter tanks 20 are connected through a liquid inlet tee pipe 24, and the liquid outlets of the pair of filter tanks 20 are connected through a liquid outlet tee pipe 26. Both the liquid inlet tee pipe 24 and the liquid outlet tee pipe 26 are provided with a three-way solenoid valve 27.

[0019] Two filter tanks 20 are connected in parallel. The wax liquid enters one of the filter tanks 20 through the inlet tee pipe 24. After being filtered through the filter cartridge 22, the wax liquid is discharged through the outlet tee pipe 26. When the filter cartridge 22 needs to be cleaned, the three-way solenoid valve 27 on the inlet tee pipe 24 and the outlet tee pipe 26 is activated, which reverses the flow so that the wax liquid flows through the other filter tank 20. Then the first filter tank 20 can be opened and the filter cartridge 22 can be taken out for cleaning.

[0020] Furthermore, the filter tank 20 is provided with a ring of filter cartridge mounting protrusions, and the top opening of the filter cartridge 22 is provided with a ring of rim. The filter cartridge 22 is movably inserted into the filter tank 20 and pressed tightly by the cover 23.

[0021] The cover 23 is fastened to the filter tank 20 by a set of screws. A set of positioning rods is arranged in a ring at the bottom of the cover 23, and a compression spring 28 is sleeved on the positioning rod. The filter cylinder 22 is pressed by a set of compression springs 28.

[0022] The compression spring 28 abuts against the filter cartridge 22. The number of compression springs 28 is the same as the number of screws, so that the top of the filter cartridge 22 is subjected to uniform force in all directions, and can fit more tightly with the filter canister 20.

[0023] Furthermore, a handle is provided on the top of the filter cartridge 22 for easy handling.

[0024] Preferably, the two heating coils 21 are connected in parallel via a pipe. When one of the filter tanks 20 is not in operation, the heating coil 21 continues to heat it to maintain the internal temperature and prevent the wax from solidifying.

[0025] Furthermore, the outer wall of the filter tank 20 is provided with a hollow insulation jacket, which is used to insulate the inside of the filter tank 20 and prevent heat loss.

[0026] Furthermore, a pressure alarm 30 is installed on the inlet tee 24. The pressure alarm 30 is used to monitor the pressure inside the filter tank 20. When the pressure exceeds the warning value, it indicates that the filter cartridge 22 is clogged and needs to be cleaned, reminding the staff to switch the filter tank 20 to clean the filter cartridge 22 inside.
