Description

Technical Field

[0001] This utility model relates to the semiconductor field, and in particular to a semiconductor wastewater defluorination device. Background Technology

[0002] The semiconductor manufacturing process generates a large amount of wastewater containing a significant amount of fluoride. To ensure that the wastewater can be recycled or discharged without affecting the environment, workers typically perform defluorination treatment. During the defluorination process, workers often stir the wastewater and additives to achieve rapid defluorination.

[0003] Current defluorination devices do not allow for the intermittent addition of reagents while stirring during wastewater defluorination, resulting in insufficient contact between the reagents and the wastewater. Furthermore, the slow accumulation of fluoride-containing precipitates after the reaction leads to incomplete separation and thus poor defluorination performance. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a semiconductor wastewater defluorination device that can intermittently add reagents while stirring to accelerate the reaction rate and can aggregate the precipitate after sedimentation to achieve better defluorination effect.

[0005] Technical Solution: A semiconductor wastewater defluorination device includes a treatment cylinder with three supporting legs fixedly connected to it. A gate is slidably connected to the treatment cylinder. A collection basin is threadedly connected to the bottom of the treatment cylinder. A fixed frame is fixedly connected to the top of the treatment cylinder. A fixed rod is fixedly connected to the fixed frame. A sliding frame is slidably connected to the fixed rod. A screw is rotatably connected to the fixed frame. The sliding frame and the screw are threadedly connected. A motor is fixedly connected to the sliding frame. The output shaft of the motor passes through the sliding frame. A transmission gear is fixedly connected to the output shaft of the motor. A sleeve is rotatably connected to the fixed frame. A stirring frame is fixedly connected to the sleeve. A first gear is fixedly connected to the top of the sleeve. The transmission gear meshes with the first gear. A scraping assembly is provided on the sleeve. A feeding assembly is provided on the fixed frame. The scraping assembly is used to scrape the sediment, and the feeding assembly is used for intermittent feeding.

[0006] In a preferred embodiment of this utility model, the surface of the gate is made of rubber.

[0007] In a preferred embodiment of the present invention, the scraping assembly includes a transmission rod, which is rotatably connected to the sleeve and passes through the sleeve. A second gear is fixedly connected to the top of the transmission rod, and a rotating frame is fixedly connected to the bottom of the transmission rod. The rotating frame contacts the inner wall of the processing cylinder.

[0008] In a preferred embodiment of this utility model, the rotating frame is made of rubber.

[0009] In a preferred embodiment of the present invention, the feeding assembly includes a feeding cylinder, which is fixedly connected to the fixed frame. A valve is provided on the feeding cylinder, and a torsion spring is connected between the feeding cylinder and the valve.

[0010] The present invention has the following advantages: 1. The output shaft of the motor rotates, which drives the transmission gear to rotate. The rotation of the transmission gear drives the sleeve to rotate through the first gear. The rotation of the sleeve drives the stirring frame to rotate, thereby stirring the wastewater. While the stirring frame is rotating, it squeezes the valve to intermittently add defluorination agent to the wastewater, thereby making the wastewater and the agent more fully in contact, thus accelerating the defluorination speed and improving the defluorination efficiency.

[0011] 2. The output shaft of the motor rotates slowly, which drives the second gear to rotate through the transmission gear. The rotation of the second gear drives the rotating frame to rotate slowly through the transmission rod. The slow rotation of the rotating frame will slowly gather the sediment into the middle of the treatment cylinder. Then the gate is closed and the collection basin is unscrewed. The sediment will remain in the collection basin, which will make the defluorination of the wastewater more complete and thus enhance the defluorination effect. Attached Figure Description

Detailed Implementation

[0019] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0020] Example 1: A semiconductor wastewater defluorination device, such as Figures 1-6 As shown, the device includes a processing cylinder 1 with three support legs 2 welded to it. A gate 3 is slidably connected to the processing cylinder 1. A collection basin 4 is threadedly connected to the bottom of the processing cylinder 1. A fixing frame 5 is welded to the top of the processing cylinder 1, and a fixing rod 6 is welded to the fixing frame 5. A sliding frame 61 is slidably connected to the fixing rod 6. A screw 7 is rotatably connected to the fixing frame 5. The sliding frame 61 and the screw 7 are threaded together. A motor 8 is fixed to the sliding frame 61 by screws. The output of the motor 8... A shaft passes through the sliding frame 61. A transmission gear 9 is connected to the output shaft of the motor 8 via a flat key. A sleeve 10 is rotatably connected to the fixed frame 5. A stirring frame 11 is fixedly connected to the sleeve 10. The stirring frame 11 is used to stir the wastewater. A first gear 12 is fixedly connected to the top of the sleeve 10. The transmission gear 9 meshes with the first gear 12. A scraping assembly is provided on the sleeve 10. A feeding assembly is provided on the fixed frame 5. The scraping assembly is used to scrape the sediment. The feeding assembly is used for intermittent feeding.

[0021] The surface of the gate 3 is made of rubber, and the rubber material of the gate 3 is used for better sealing.

[0022] The scraping assembly includes a transmission rod 13, which is rotatably connected to the sleeve 10 and passes through the sleeve 10. A second gear 14 is fixedly connected to the top of the transmission rod 13, and a rotating frame 15 is fixedly connected to the bottom of the transmission rod 13. The rotating frame 15 contacts the inner wall of the processing cylinder 1 and is used to collect sediment.

[0023] The rotating frame 15 is made of rubber, and the rubber rotating frame 15 is used to achieve more complete aggregation.

[0024] The feeding assembly includes a feeding cylinder 16, which is fixedly connected to the fixed frame 5. A valve 17 is provided on the feeding cylinder 16, and a torsion spring 18 is connected between the feeding cylinder 16 and the valve 17.

[0025] When defluorination of semiconductor wastewater is required, the operator first places the wastewater into the treatment cylinder 1, opens the gate 3, and puts an appropriate amount of defluorination agent into the feeding cylinder 16. Then, the operator controls the output shaft of the motor 8 to rotate. The rotation of the output shaft of the motor 8 drives the transmission gear 9 to rotate, which in turn drives the sleeve 10 to rotate via the first gear 12. The rotation of the sleeve 10 drives the agitator 11 to rotate, thus agitating the wastewater. Simultaneously, the rotation of the agitator 11 compresses the valve 17, causing it to rotate. This causes the torsion spring 18 to twist, and the rotation of the valve 17 causes the defluorination agent to fall from the feeding cylinder 16 into the wastewater. The agitator 11 continues to rotate and stops compressing the valve 17. The torsion spring 18 resets, causing the valve 17 to reset and close. This process is repeated. The rotation of the agitator 11 compresses the valve 17, intermittently adding defluorination agent to the wastewater, thus ensuring more thorough contact between the wastewater and the agent, thereby accelerating defluorination. The speed of the reaction between the defluorinating agent and the wastewater will increase the efficiency of defluorination. After the reaction has been going on for a period of time, the motor 8 is turned off and the sedimentation is allowed to continue. Then, the operator rotates the screw 7 to move the sliding frame 61 upward through the thread. The upward movement of the sliding frame 61 causes the transmission gear 9 to disengage from the first gear 12. The sliding frame 61 continues to move upward, and the transmission gear 9 engages with the second gear 14. Then, the operator controls the output shaft of the motor 8 to rotate slowly. The slow rotation of the output shaft of the motor 8 drives the second gear 14 to rotate through the transmission gear 9. The rotation of the second gear 14 drives the rotating frame 15 to rotate slowly through the transmission rod 13. The slow rotation of the rotating frame 15 will slowly gather the sediment towards the middle of the treatment cylinder 1. Then, the gate is closed and the collection basin 4 is unscrewed. The sediment will remain in the collection basin 4, which will make the defluorination of the wastewater more complete and enhance the defluorination effect. Finally, the operator opens the gate again to discharge the defluorinated wastewater.
