Description

Technical Field

[0001] This utility model relates to the technical field of degreasing furnace accessories, specifically to a degreasing furnace heat exchange tube purging structure. Background Technology

[0002] A combustion degreasing furnace is a mechanical device that removes grease from the surface of a workpiece by heating it to evaporate and burn off the grease. Combustion degreasing furnaces can be combined with carburizing furnaces (or nitriding furnaces) to form a single unit, utilizing the combustible exhaust gas from the carburizing furnace as the heat source for the degreasing furnace.

[0003] Chinese Patent Publication No. CN215864720U discloses a casing, in which a heat exchange tube is rotatably inserted into the top of the casing. An inlet pipe is fixedly inserted into the casing at one end of the heat exchange tube. An exhaust fan is fixedly installed on the side of the casing away from the inlet pipe. A rotating mechanism is fixedly installed at the end of the heat exchange tube located near the inlet pipe. A mounting box is movably fitted onto the end of the heat exchange tube away from the inlet pipe. A filter box is movably inserted into the mounting box on one side of the casing door. An adsorption box is movably inserted into the mounting box on one side of the filter box. A water spray pipe is fixedly installed on the inner side of the top of the casing above the heat exchange tube. This high-efficiency, energy-saving gas-fired thermal degreasing furnace fume treatment system and waste heat recovery system facilitates the filtration, adsorption, and purification of oil fumes before discharge, thereby preventing air pollution. Furthermore, the heat absorbed by the heat exchange tube is used to heat water, thus recovering and utilizing the heat from the oil fumes.

[0004] However, although the aforementioned patent utilizes the waste gas generated by the degreasing furnace through heat exchange tubes, this waste gas contains a large amount of easily deposited substances. These substances tend to adhere to the inner wall of the heat exchange tubes while losing heat, thus affecting the heat exchange effect, wasting heat resources, and impacting the normal use of the equipment.

[0008] The cleaning box is located on top of the heat exchange equipment of the degreasing furnace;

[0009] The cleaning mechanism, located inside the heat exchange tubes, is used to clean the dirt adhering to the inner wall of the heat exchange tubes.

[0010] The flow divider is arranged on the heat exchange tubes and the air inlet pipe to cut off the airflow in the heat exchange tubes and the air inlet pipe.

[0011] An air-blowing and flushing mechanism is located outside the heat exchange equipment of the degreasing furnace and is used to generate airflow to assist the cleaning mechanism in cleaning.

[0012] The cleaning mechanism also includes movable components for movement and piping components connecting the heat exchange tubes and the cleaning box. The air-blowing flushing mechanism also includes a filter component for filtering dirt and a maintenance component for easy maintenance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0055] Example 1:

[0056] like Figures 1 to 5 As shown, this utility model provides a degreasing furnace heat exchanger tube purging structure, a degreasing furnace heat exchanger 1, a degreasing furnace heat exchanger 1 with heat exchanger tubes 101 and air inlet pipes 102 arranged on the degreasing furnace heat exchanger 1, and also includes a cleaning box 2 arranged on the top of the degreasing furnace heat exchanger 1, a cleaning mechanism arranged inside the heat exchanger tubes 101 for cleaning stains adhering to the inner wall of the heat exchanger tubes 101, a diversion mechanism arranged on the heat exchanger tubes 101 and air inlet pipes 102 for cutting off the air flow in the heat exchanger tubes 101 and air inlet pipes 102, and an air blowing and flushing mechanism arranged outside the degreasing furnace heat exchanger 1 for generating airflow to assist the cleaning mechanism in cleaning;

[0057] The cleaning mechanism also includes movable components for movement and piping components connecting the heat exchange tube 101 and the cleaning box 2. The air blowing and flushing mechanism also includes a filter component for filtering dirt and a maintenance component for easy maintenance.

[0058] Specifically, the cleaning mechanism includes a cleaning motor 201 arranged inside the cleaning box 2 to provide rotational power, a telescopic pipe 202 arranged at the output end of the cleaning motor 201 to protect the cleaning mechanism, an elastic deformable rod 204 arranged at the output end of the cleaning motor 201, and bristles 205 arranged on the elastic deformable rod 204 to rotate and clean the inner wall of the heat exchange tube 101 in conjunction with the elastic deformable rod 204. The elastic deformable rod 204 and the bristles 205 rotate on the inner wall of the heat exchange tube 101 to remove the dirt attached to the inner wall of the pipe by means of physical friction.

[0059] Specifically, the piping assembly includes a delivery pipe 203 arranged between the cleaning chamber 2 and the air inlet pipe 102 for connecting the cleaning chamber 2 and the heat exchange pipe 101, and a gate valve 302 arranged at one end of the delivery pipe 203 near the air inlet pipe 102 for sealing and isolating the delivery pipe 203 from the air inlet pipe 102. When the gate valve 302 is opened, the delivery pipe 203 can be connected to the heat exchange pipe 101.

[0060] Specifically, the active component includes a linear module 206 arranged on the bottom side of the cleaning box 2, and an electronic slide 207 arranged on the linear module 206 to move the cleaning motor 201 in position. The linear module 206 and the electronic slide 207 are used to move the cleaning motor 201 in position.

[0061] Specifically, the maintenance components include mounting plates 407 arranged at both ends of the filter cartridge 406 and connected to mounting base 1 404 and mounting base 2 405 respectively, mounting plate 409 arranged on the bottom side of the air pump 4, and maintenance and inspection door 410 arranged on the side of the filter box 402. The maintenance and inspection door 410 allows users to easily maintain and replace the filter cartridge 406 inside the filter box 402.

[0062] Example 2:

[0063] Based on Example 1, in order to further enhance the cleaning effect, while the lower elastic deformable rod and brush bristles are cleaning, a high-speed gas flow is generated by an air pump and circulates inside the heat exchange tube, thereby transporting the cleaned dust to the outside of the heat exchange tube.

[0064] Specifically, the air blowing and flushing mechanism includes an air pump 4 arranged outside the heat exchange equipment 1 of the degreasing furnace, a first pipe 401 arranged at the output end of the air pump 4, a filter box 402 arranged at the output end of the first pipe 401, and a second pipe 403 arranged at the output end of the second check valve 303. The air is delivered to the filter box 402 through the second check valve 303 and the second pipe 403, and the air can return to the heat exchange tube 101 through the first pipe 401 and the air pump 4.

[0065] Specifically, the filter assembly includes a mounting base 404 arranged inside the filter box 402 and connected to the first pipe 401, a mounting base 405 arranged inside the filter box 402 and connected to the second pipe 403, a filter cartridge 406 arranged between the mounting base 404 and the second mounting base 405, the mounting base 404 and the second mounting base 405 being the base for mounting the filter cartridge 406, the filter cartridge 406 being easily replaceable via the mounting plate 407, and a filter bag 408 arranged inside the filter cartridge 406 for filtering the air flowing through it, with filtration performed through the filter bag 408 inside the filter cartridge 406.

[0066] Example 3:

[0067] Based on Example 1, in order to avoid dust spread, a control valve system was formed by using a three-way valve, a check valve one, a slide gate valve, and a check valve two.

[0068] Specifically, the diversion mechanism includes a three-way valve 3 arranged on the heat exchange equipment 1 of the degreasing furnace, a one-way valve 301 arranged on the air inlet pipe 102, and a one-way valve 303 arranged on the conveying pipe 203. In the non-clean state, the three-way valve 3 and the one-way valve 301 are normally open, while the gate valve 302 and the one-way valve 303 are normally closed to prevent hot air from entering the cleaning box 2 and the air pump 4.

[0069] Working principle: During cleaning, the heat exchange tube 101 needs to be switched to sealed rotation for the degreasing furnace heat exchange equipment 1 via three-way valve 3 and one-way valve 301. Then, the cleaning motor 201 can be moved using the linear module 206 and electronic slide 207. The movement of the cleaning motor 201 causes the elastic deformation rod 204 and bristles 205 to move within the cleaning motor 201, the conveying pipe 203, and the heat exchange tube 101, ensuring that the bristles 205 make full contact with the inside of the heat exchange tube 101, allowing cleaning to begin. If compressed air is required, the heat exchange tube 101 can be connected to the air pump 4 via three-way valve 3 and one-way valve 303. The air pump 4 pumps air into the heat exchange tube 101 through the three-way valve 3. The air flows rapidly through the heat exchange tube 101, washing away the dust cleaned by the bristles 205. It is then transported to the filter box 402 through the second check valve 303 and the second pipe 403. The air is then filtered by the filter bag 408 inside the filter cartridge 406. The clean air can then return to the heat exchange tube 101 through the first pipe 401 and the air pump 4. The rotation of the bristles 205 and the air circulation achieve efficient cleaning. In the non-cleaning state, the three-way valve 3 and the first check valve 301 are normally open, while the gate valve 302 and the second check valve 303 are normally closed to prevent hot air from entering the cleaning box 2 and the air pump 4. The filter cartridge 406 needs to be replaced regularly to prevent excessive dust from affecting the filtration effect. The filter cartridge 406 can be installed and removed through the mounting plate 407.

[0070] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
