Description

Technical Field

[0001] This utility model belongs to the field of surface treatment equipment technology, and more specifically relates to a descaling tank circulating stirring mechanism. Background Technology

[0002] Before quenching, the oxide scale (commonly known as "phosphorus scale") on the surface of parts needs to be removed. Therefore, before quenching, the parts need to be immersed in a descaling solution to remove the surface phosphorus scale. In continuous quenching furnace equipment, the parts are continuously fed into the descaling tank containing the descaling solution by a conveyor belt. Currently, the commonly used descaling agents are insoluble or slightly soluble in water. Therefore, a circulating stirring mechanism is usually set in the descaling tank to stir and replenish the descaling solution, so as to avoid the descaling agent settling to the bottom and the concentration decreasing, which would affect the descaling effect of the parts.

[0003] The stirring mechanism typically consists of one or two stirring shafts that are inserted obliquely into the solution. The stirring shafts are equipped with spiral stirring blades and are driven by a motor. The stirring shafts are usually located on both sides of the conveyor belt.

[0004] The current problem with this type of stirring mechanism is that if it is stirred quickly, it will cause too much foam in the solution. The foam will burst on the surface of the solution and cause the solution to splash, affecting the surrounding production environment. However, if it is stirred slowly, it cannot be stirred effectively, and too much of the descaling agent will still settle to the bottom. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a descaling tank circulation stirring mechanism that enables the stirring shaft to oscillate back and forth within the descaling tank, thereby improving the circulation stirring effect of the solution.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circulating stirring mechanism for a descaling tank, wherein circulating stirring mechanisms are provided on both sides of the conveyor belt in the descaling tank, the circulating stirring mechanism includes a drive motor, a motor support plate, a shaft sleeve, and a stirring shaft, the drive motor is located on the motor support plate, the stirring shaft is connected to the output shaft of the drive motor and passes through the shaft sleeve, the stirring shaft is provided with stirring blades, the motor support plate is located at the top of the descaling tank, the motor support plate is provided with first support blocks on both sides, the first support blocks are provided with first arc grooves, the motor support plate is provided with first rollers corresponding to the first arc grooves, the shaft sleeve is provided with second support blocks on both sides, the second support blocks are provided with second arc grooves, the shaft sleeve is provided with second rollers corresponding to the second arc grooves, and a drive mechanism is connected to the motor support plate.

[0007] Furthermore, the drive mechanism includes a cylinder, and a connecting rod is hinged to the piston rod of the cylinder, the connecting rod being hinged to the motor support plate.

[0008] Furthermore, cylinders are provided on both sides of the motor support plate.

[0009] Furthermore, a bearing is provided between the bushing and the stirring shaft.

[0010] Furthermore, the second support block is located inside the descaling tank, and a support frame is provided inside the descaling tank, with the second support block located inside the support frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: during the cyclic stirring, the drive mechanism causes the drive motor and the stirring shaft to oscillate back and forth, while the drive motor drives the stirring shaft to rotate, so that the stirring shaft can stir at a relatively low speed, thereby improving the cyclic stirring effect of the solution.

[0016] Reference Figure 1 and Figure 2The present invention will be further described below.

[0017] A circulating stirring mechanism for a descaling tank is provided. Both sides of the conveyor belt 16 inside the descaling tank are equipped with circulating stirring mechanisms. Each circulating stirring mechanism includes a drive motor 1, a motor support plate 2, a bushing 3, and a stirring shaft 4. The drive motor 1 is located on the motor support plate 2. The stirring shaft 4 is connected to the output shaft of the drive motor 1 and passes through the bushing 3. Stirring blades 5 are provided on the stirring shaft 4. The motor support plate 2 is located at the top of the descaling tank. First support blocks 6 are provided on both sides of the motor support plate 2, and first arc grooves 7 are provided on the first support blocks 6. First rollers 8 corresponding to the first arc grooves 7 are provided on the motor support plate 2. Second support blocks 9 are provided on both sides of the bushing 3, and second arc grooves 10 are provided on the second support blocks 9. Second rollers 11 corresponding to the second arc grooves 10 are provided on the bushing 3. A drive mechanism is connected to the motor support plate 2.

[0018] like Figure 1 and Figure 2 As shown, during the cyclic stirring, the drive mechanism drives the motor support plate 2 to swing back and forth along the first arc groove 7 on the first support block 6. At the same time, the drive motor 1 drives the stirring shaft 4 to rotate, so that the stirring shaft 4 rotates while swinging back and forth in the solution in the dephosphorization tank, so that the stirring shaft 4 can improve the cyclic stirring effect of the solution by stirring at a relatively low speed.

[0019] Specifically, the stability of the oscillation of the stirring shaft 4 is improved by the shaft sleeve 3 and the second support block 9. Specifically, the smoothness of the oscillation is improved by the first roller 8 and the second roller 11. Specifically, the center of the arc surface of the second arc groove 10 is concentric with the center of the arc surface of the first arc groove 7.

Specifically, the connecting rod 13 transforms the reciprocating linear motion of the piston rod of the cylinder 12 into the sliding motion of the motor support plate 2 on the first support block 6.

[0021] like Figure 2 As shown in this example, preferably, cylinders 12 are provided on both sides of the motor support plate 2. The two cylinders 12 drive the motor support plate 2 synchronously, thereby increasing the driving force for the swing of the motor support plate 2.

[0023] like Figure 2 As shown, in this example, preferably, the second support block 9 is located inside the descaling tank, and a support frame 14 is provided inside the descaling tank, with the second support block 9 located inside the support frame 14.
