Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger cleaning, in particular to a fin type heat exchanger dust cleaning tool. Background Art

[0002] During the long-term use of the finned heat exchanger, dust and other impurities will cover the fins, forming an insulation layer, blocking the transfer of heat, thereby affecting the heat exchange efficiency of the heat exchanger and reducing the performance of the heat exchanger;

[0003] In the prior art, commonly used cleaning methods include mechanical vibration, high-pressure water jet, high-pressure air jet and sweeping; the mechanical vibration method is suitable for use in situations where dust is not firmly attached, while the high-pressure water jet method and the high-pressure air jet method can exert a greater impact force on dust attached to local positions of the heat exchanger, but require a longer cleaning time, and are accompanied by water escape and large-scale dust, which has an adverse effect on the environment of the equipment placement space; therefore, the present application provides a fin heat exchanger cleaning tool. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a finned heat exchanger cleaning tool, which can cover a large area of ​​the fins on the outside of the heat exchange tubes to ensure the cleaning efficiency of the dust attached to the outside of the fins.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A fin-type heat exchanger cleaning tool is provided, comprising a clamping seat and two cleaning arms, wherein the clamping seat is detachably fixedly mounted on the upper side of a frame, the two cleaning arms are respectively located on both sides of the frame, a plurality of arc-shaped brush heads are fixedly mounted on the cleaning arms, a heat exchange tube is coiled on the inner side of the frame, fins are arranged on the outer side of the heat exchange tube, and a plurality of bristles on the brush heads on both sides of the frame can simultaneously cover the outer circumference of the fins.

[0007] Furthermore, a double-sided groove frame is fixedly installed on the clamping seat, and sliding blocks are slidably installed on both sides of the double-sided groove frame, and the cleaning arm is slidably connected to the sliding blocks.

[0008] Furthermore, a round rod is fixedly installed on the top of the cleaning arm, and a double-sided groove arm is rotatably installed on the top of the clamping seat, and sliding grooves for the round rod to slide are respectively arranged on both sides of the double-sided groove arm.

[0009] Furthermore, gears are rotatably mounted on the double-sided groove frames, and rack plates are respectively connected to both sides of the gears through meshing transmission, and the two rack plates are respectively fixedly connected to the two sliding blocks.

[0010] Furthermore, a motor I for driving the gear to rotate is installed on the clamping seat.

[0011] Furthermore, a motor II for driving the double-sided slot arms to rotate is installed on the clamping seat.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The fin-type heat exchanger cleaning tool of the utility model controls the cleaning arms on both sides of the frame to move synchronously. Under the joint action of multiple brush heads on the sides of the two cleaning arms, the bristles on the brush heads clean the dust and other impurities attached to the outside of the fins, thereby cleaning the fins in all directions and ensuring the cleaning efficiency of the dust attached to the outside of the fins.

[0014] 2. The fin-type heat exchanger cleaning tool of the utility model example has an arc-shaped brush head, which can stably act on the fins on the outside of the heat exchange tubes and play a certain shielding role, thereby effectively limiting the escape of dust and other impurities detached from the fins into the air.

[0015] 3. In the finned heat exchanger cleaning tool of the utility model example, the cleaning arm is connected to the clamping seat through a double-sided slot frame and a slider, so that the distance between the two cleaning arms can be adjusted to adapt to heat exchange tubes of different diameters, thereby improving the cleaning effect of the tool for radiator products of different models.
