Description

Technical Field

[0001] The utility model relates to the field of smoke exhaust turning mechanisms, in particular to a smoke exhaust turning mechanism for the foundry industry. Background Art

[0002] The foundry industry generates a large amount of smoke and dust during the production process, which mainly come from metal melting, sand drying, paint volatilization and other links. The smoke contains a variety of harmful substances, such as dust, sulfur dioxide, nitrogen oxides, carbon monoxide, carbon dioxide and a variety of organic waste gases. These harmful substances not only have a serious impact on human health, so ensuring that the smoke and harmful gases in the casting process are effectively removed is an effective smoke exhaust solution that the foundry industry has been seeking.

[0003] Although traditional smoke exhaust equipment can remove smoke to a certain extent, it is often difficult to meet the smoke exhaust needs at different positions and angles in casting operations due to its fixedness and the limitations of the smoke exhaust angle. It is also unable to remove harmful substances and particulate matter, making it difficult to ensure that the emitted smoke meets environmental protection standards. For this reason, we have proposed a smoke exhaust flip mechanism for the foundry industry. Utility Model Content

[0025] The pipe turning device 17 is arranged on the outside of the smoking pipe 7, and is used to drive the pipe to move and play a supporting role. The pipe turning device 17 includes a support arm 8, a fixing plate 9, a smoking dust port 10 and a pipe fixing sleeve 13. The fixing plate 9 is fixedly installed on the wall, and the support arm 8 is hinged on the fixing plate 9. The end of the support arm 8 away from the fixing plate 9 is fixedly connected to the smoking dust port 10. The support arm 8 is fixedly connected to a plurality of pipe fixing sleeves 13. The support arm 8 is fixedly connected to the smoking pipe 7 through the pipe fixing sleeves 13, and the end of the smoking pipe 7 away from the smoke extractor 2 is fixedly connected to the smoking dust port 10;

[0026] The filter device 18 is arranged in the inner cavity of the smoke exhaust filter box 1 and is used to filter the absorbed smoke.

[0027] Furthermore, the support arm 8 is hinged by a plurality of support rods, and a hydraulic support rod 12 is fixedly connected to each support rod on the support arm 8. One end of the support arm 8 close to the smoke inlet 10 is fixedly connected to a handheld gripper 11.

[0028] Furthermore, a pipe fixing sleeve 13 is fixedly connected to the inner cavity of the smoke exhaust filter box 1, and the pipe fixing sleeve 13 divides the smoke exhaust filter box 1 into an upper half smoke collecting chamber and a lower half smoke exhaust chamber.

[0029] Furthermore, the upper end of the connecting pipe 4 extends into the smoke exhaust filter box 1 and is connected to the smoke collecting chamber, and the other end of the connecting pipe 4 is connected to the inner cavity of the catalyst tank 5, in which activated carbon catalyst and metal oxide catalyst are placed.

[0030] Furthermore, the filtering device 18 includes a smoke filter core 14, a filter layer 15 and a skeleton 16. Four smoke filter cores 14 arranged in a matrix are fixedly inserted on the upper surface of the pipe fixing sleeve 13. The outer side surface of the smoke filter core 14 is fixedly connected to the filter layer 15. The outer side surface of the filter layer 15 is fixedly connected to a plurality of skeletons 16 arranged in a ring shape.

[0031] Working principle: When the device is used to discharge smoke generated by casting, the driving motor 3 is first turned on, and the driving motor 3 drives the smoke extractor 2 to work to generate negative pressure, so that the smoking duct 7 connected to the air intake port of the smoke extractor 2 sucks in the indoor air and smoke through the smoke intake port 10. During the inhalation process, since the smoking duct 7 is fixed to the support arm 8 by the duct fixing sleeve 13, the position of the support arm 8 can be controlled by pulling the hand-held gripper 11, so that the smoking duct 7 can be driven to form different positions and angles to ensure that the smoke can be effectively inhaled, and the position of the support arm 8 is limited by the hydraulic support rod 12 connected to the support arm 8 to play a supporting role. The smoke after inhalation passes through the exhaust port of the smoke extractor 2 and enters the collection area of ​​the smoke exhaust filter box 1. After entering the smoke chamber, it will react with the activated carbon catalyst and metal oxide catalyst placed in the catalyst tank. These catalysts can catalyze the oxidation of harmful substances in the smoke and convert them into low-toxic or non-toxic substances. Due to the pressure of the exhaust port of the upper smoke exhaust fan 2, the smoke passes through the smoke filter element 14 and moves to the smoke exhaust chamber in the smoke exhaust filter box 1. The smoke filter element 14 and the filter layer 15 can effectively capture and separate particulate matter and harmful gases in the smoke, while the skeleton 16 plays a role in supporting and fixing the filter layer. Finally, the purified gas is discharged to the outside through the smoke exhaust pipe 6. Through such a series of work processes, the entire system realizes the effective removal and purification of the smoke generated in the casting process, ensuring the cleanliness of the working environment and the health of the personnel.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
