Description

Technical Field

[0001] This utility model relates to the field of quenching tank flue gas treatment technology, specifically a quenching tank flue gas guiding mechanism. Background Technology

[0002] A quenching tank is a container filled with quenching media. It is mainly used to ensure that the workpiece completes the quenching operation at a reasonable cooling rate and uniformly so that the workpiece meets the technical requirements. Quenching tanks are usually welded from steel plates and can be cubic or cylindrical in shape. They can be filled with different quenching media, such as water, brine, oil or organic solutions. The specific choice depends on the material, shape, size and processing requirements of the workpiece.

[0003] Currently used quenching tanks lack the ability to guide and discharge flue gas. When a workpiece is immersed in the quenching medium from a high temperature, a large amount of flue gas will be rapidly released. This flue gas contains steam, fine particles and hydrocarbons. If it is discharged into the processing environment at will, it will cause pollution and affect the health of workers.

[0004] Based on this, the present invention designs a quenching tank flue gas guiding mechanism to solve the above problems. Summary of the Invention

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quenching tank flue gas guiding mechanism, comprising: a quenching tank body; and further comprising a flue gas hood, a guiding part, and a lifting part;

[0007] The guide section includes an exhaust fan, a telescopic hose fixed to the exhaust fan outlet, and a connecting collar slidably connected to the exhaust fan inlet and the telescopic hose outlet respectively.

[0008] The lifting unit includes two symmetrical supports fixed to the outer wall of the quenching tank, a motor fixed to one end of the supports, and a lead screw fixed to the drive end of the motor.

[0009] The fume hood includes a threaded connector fixed to its top and two symmetrical lead screw blocks fixed to the outer wall of the fume hood. The connecting collar at the air inlet end of the exhaust fan is threadedly connected to one end of the threaded connector.

[0010] Preferably, the fume hood further includes multiple connecting rods fixed to the bottom, one end of each connecting rod being fixed with a support plate, and the outer wall of the support plate being provided with multiple leakage holes in sequence.

[0011] Preferably, the two lead screw sleeves are threadedly connected to the outer walls of the two lead screws respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Firstly, the exhaust fan in the guide section, in conjunction with the fume hood, draws the fumes generated in the quenching tank into the telescopic hose, which then guides them to the connected main exhaust duct, thus preventing the fumes from being randomly discharged into the processing environment and causing pollution, which could affect the health of the workers.

[0027] The guide section includes an exhaust fan 4, a telescopic hose 5 fixed to the exhaust fan 4 outlet end, and a connecting collar 6 slidably connected to the exhaust fan 4 inlet end and the telescopic hose 5 outlet end respectively.

[0028] The lifting unit includes two symmetrical supports 8 fixed to the outer wall of the quenching tank 1, a motor 9 fixed to one end of the supports 8, and a lead screw 10 fixed to the drive end of the motor 9.

[0030] The top of the quenching tank 1 is a slot to store the quenching medium. The slot can be sealed by the fume hood 2. The exhaust fan 4 of the guide section and the telescopic hose 5 work together with the fume hood 2 to draw in the quenching fumes generated by the workpiece in the quenching tank and guide them to the main exhaust pipe, avoiding random discharge into the processing environment. Before operation, the telescopic hose 5 is connected to the threaded joint of the main ventilation pipe through the connecting collar 6 at one end. The telescopic hose 5 is flexible and can be connected to the main ventilation pipe in more directions and over more distances. It can also be used with the fume hood 2 for lifting and lowering operations through the lifting section. The fume hood 2 is connected to the exhaust fan 4 through the threaded pipe 3 and the connecting collar 6. The connecting collar 6 can slide and rotate to facilitate the connection operation.

[0031] More preferably, the fume hood 2 also includes a plurality of connecting rods 12 fixed to the bottom, one end of the connecting rod 12 is fixed with a support plate 13, and a plurality of leakage holes 14 are sequentially opened on the outer wall of the support plate 13;

[0032] The fume hood 2 is connected to the support plate 13 via the connecting rod 12. The workpiece to be quenched is placed on the support plate 13. The support plate 13 rises and falls synchronously with the fume hood 2 to assist in the loading and unloading of the workpiece. Multiple holes 14 on the outer wall of the support plate 13 ensure smooth flow of the quenching medium, making the lifting and lowering of the support plate 13 easier.

[0033] More preferably, the two lead screw sleeves 11 are respectively threaded to the outer walls of the two lead screws 10;

[0034] The smoke hood 2 is connected to two lead screws 10 via a lead screw sleeve 11. Both lead screws 10 are rotated synchronously by a motor 9. After rotation, the smoke hood 2 can be raised and lowered synchronously by the two lead screw sleeves 11.

[0035] In a further preferred embodiment, a plurality of lever blocks 7 are sequentially fixed to the outer wall of the connecting collar 6;

[0036] The lever 7 allows workers to more easily rotate the connecting collar 6 to perform disassembly, assembly, and maintenance operations.

[0037] More preferably, the end of the lead screw 10 away from the motor 9 is rotatably connected to the outer wall of the quenching tank 1;

[0038] One end of the lead screw 10 is rotatably connected to the quenching tank 1 to stabilize and assist in the lifting operation.

[0039] A specific application of this embodiment is as follows: a workpiece heated at high temperature is placed on top of the pallet 13. The motors 9 of the two supports 8 control the two lead screws 10 to rotate forward or backward. When the lead screws 10 rotate, they will drive the lead screw sleeve 11 to move up and down, thereby causing the fume hood 2, connecting rod 12, pallet 13 and guide part to move up and down. The pallet 13 at one end of the connecting rod 12 is inserted into the quenching tank 1 for quenching. At the same time as the movement, the exhaust fan 4 in the guide part runs, drawing the fumes generated in the quenching tank 1 from the fume hood 2 into the telescopic hose 5, and then guiding them to the connected main exhaust pipe.
