Description

Technical Field

[0001] This invention relates to the field of chemical equipment technology, specifically to a chemical diversion box waste liquid discharge device. Background Technology

[0002] In the chemical production process, chemical distribution boxes are an indispensable piece of equipment. However, traditional chemical distribution boxes have some problems in their waste outlet design. The waste outlet of traditional chemical distribution boxes is often too narrow, which can easily cause poor waste liquid discharge and blockage. Solid particles and impurities in the waste liquid can easily accumulate at the waste outlet, resulting in a slowdown in discharge speed or even complete blockage. This not only affects production efficiency, but may also cause chemicals to remain in the distribution box, increasing safety risks. Traditional chemical distribution box waste outlets often lack effective filtration mechanisms, causing solid particles and impurities in the waste liquid to be directly discharged into the environment. This not only increases the risk of environmental pollution, but may also damage downstream treatment equipment. Although some designs install simple filtration devices before the waste outlet, these devices often have poor filtration effects and are prone to blockage, requiring frequent cleaning and replacement.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention accelerates the liquid inlet by driving the liquid inlet hopper to rotate and using a spiral to create a vortex in the waste liquid at the bottom of the chemical separator. A cam pushes the lifting rod upward, which in turn drives the lifting plate to rise. Then, a first spring drives the lifting rod to return to its original position, thus forming a reciprocating motion. This causes the lifting plate to move up and down continuously at the top of the liquid inlet hopper, further assisting the liquid inlet and accelerating the liquid discharge. The minimum gap formed between the motor and the farthest end of the horizontal shaft and the inner wall of the fixed tube is used to crush large pieces of sediment entering the fixed tube, preventing large pieces of sediment from clogging the fixed tube.

[0018] 2. This invention uses a reciprocating plate within a drive support frame to perform reciprocating motion, and uses an airbag to fill the discharge hopper with air to increase the pressure inside the discharge hopper, thereby assisting the filtration speed and improving the discharge speed of the waste liquid. After the filtered waste liquid enters the flow-limiting pipe, the discharge flow rate is adjusted by regulating the gap between the flow-limiting plate and the inner wall of the flow-limiting pipe. The adjustment sleeve is kept stable by the threaded connection between the adjustment sleeve and the threaded pipe, so as to ensure that the flow-limiting plate stably controls the discharge flow rate of the flow-limiting pipe.

[0036] The discharge mechanism 2 includes a spiral strip 204, a connecting frame 205, a lifting rod 206, and a lifting plate 207.

By driving the inlet hopper 203 to rotate, when the inlet hopper 203 rotates, the spiral strips 204 cause the waste liquid at the bottom of the chemical separator 1 to generate a vortex, thereby accelerating the inlet speed.

[0037] The discharge mechanism 2 includes a lifting groove 208, a limiting rod 209, a first spring 210, and a sealing sleeve 211.

Through the minimum gap formed between the farthest end of the motor 305 and the horizontal shaft 303 and the inner wall of the fixed tube 302, large pieces of sediment entering the fixed tube 302 are squeezed and broken up, so as to avoid large pieces of sediment clogging the fixed tube 302.

[0039] The pressurized filter mechanism 4 includes an inlet one-way valve 403, an outlet one-way valve 404, and a second spring 407. The inlet one-way valve 403 is inserted and fixedly installed at the top center of the support frame 401 away from the reciprocating plate 405.

At this time, the reciprocating plate 405 drives the airbag 406 to extend, and draws air through the inlet one-way valve 403 and fills the discharge hopper 202 with air through the outlet one-way valve 404 to increase the pressure inside the discharge hopper 202, assist the filtration speed inside the discharge hopper 202, and improve the discharge speed of waste liquid;

[0040] The pressurized filtration mechanism 4 includes a movable groove 408, a movable toothed plate 409, and a vertical shaft 410. The movable groove 408 is located in the middle of the side of the pressurized box 402 near the discharge hopper 202. One end of the movable toothed plate 409 is fixedly installed on the middle of the side of the reciprocating plate 405 near the discharge hopper 202 by bolts. The end of the movable toothed plate 409 connected to the reciprocating plate 405 is inserted and movably installed in the movable groove 408. The top end of the vertical shaft 410 is movably installed on the top end of the support frame 401 by bearings.

[0041] The flow limiting mechanism 5 includes a second gear 411, a fixed toothed plate 412, and an intake pipe 413.

The fixed toothed plate 412 drives the second gear 411 to rotate, and the second gear 411 drives the movable toothed plate 409 to move along the movable groove 408 on the inner side wall of the booster box 402.

[0042] The flow limiting mechanism 5 includes a rod groove 504, a threaded tube 505, an adjusting rod 506, an adjusting sleeve 507, and an adjusting plate 508. The rod groove 504 is located at one end of the rotating shaft 502 outside the flow limiting tube 501. The threaded tube 505 is bolted to the middle of the side wall of the flow limiting tube 501 and is movably sleeved on the end of the rotating shaft 502 outside the flow limiting tube 501. The adjusting rod 506 is inserted and movably installed in the rod groove 504. The adjusting sleeve 507 is threaded and movably sleeved on the outside of the threaded tube 505. The end of the adjusting rod 506 away from the flow limiting plate 503 is bolted to the middle of the inside of the adjusting sleeve 507. The adjusting plate 508 is bolted to the middle of the adjusting sleeve 507. The adjusting sleeve 507 is fixedly installed at the end away from the rotating shaft 502. The adjusting sleeve 507 is rotated by rotating the adjusting plate 508, so that the adjusting sleeve 507 rotates on the threaded tube 505. The adjusting sleeve 507 is kept stable by the threaded connection between the adjusting sleeve 507 and the threaded tube 505. When the adjusting sleeve 507 rotates on the threaded tube 505, it drives the adjusting rod 506 to rotate into the rod groove 504. The adjusting rod 506 engages with the rod groove 504, which drives the rotating shaft 502 to rotate at the same time. The rotating shaft 502 then drives the flow limiting plate 503 to rotate. The discharge flow rate is adjusted by adjusting the gap between the flow limiting plate 503 and the inner wall of the flow limiting tube 501.

[0043] Working principle: When in use, the waste liquid discharged from the chemical separator 1 enters the discharge hopper 202 through the inlet hopper 203. The motor 305 is started, which drives the first gear 307 to rotate. When the first gear 307 rotates, it drives the inlet hopper 203 to rotate through the gear ring 306. When the inlet hopper 203 rotates, the spiral strip 204 causes the waste liquid at the bottom of the chemical separator 1 to generate a vortex to accelerate the liquid inlet speed.

[0044] After the motor 305 starts, it drives the horizontal shaft 303 to rotate. The horizontal shaft 303 drives the cam 304 inside the fixed tube 302 to rotate. The cam 304 pushes the lifting rod 206 upward, which in turn drives the lifting plate 207 to rise. Then, the first spring 210 drives the lifting rod 206 to return to its original position, thus forming a reciprocating motion. This causes the lifting plate 207 to move up and down continuously at the top of the liquid inlet hopper 203, further assisting in liquid intake and accelerating the liquid discharge speed. When the liquid inlet hopper 203... When rotating, the connecting frame 205 rotates accordingly. The limiting rod 209 is inserted into the lifting groove 208 to drive the lifting rod 206, which moves up and down, to rotate. This causes the lifting plate 207 to rotate simultaneously with the liquid inlet hopper 203, which not only prevents blockage but also speeds up the liquid inlet. Furthermore, the minimum gap formed between the motor 305 and the farthest end of the horizontal shaft 303 and the inner wall of the fixed tube 302 allows large pieces of sediment entering the fixed tube 302 to be squeezed and broken up, preventing large pieces of sediment from clogging the fixed tube 302.

[0045] When the inlet hopper 203 rotates, the fixed toothed plate 412 on its side wall rotates accordingly. The fixed toothed plate 412 drives the second gear 411 to rotate, which in turn drives the movable toothed plate 409 to move along the movable groove 408 on the inner side wall of the booster box 402. Then, the movable toothed plate 409 drives the reciprocating plate 405 to rotate within the booster box 402 around the discharge hopper 202. At this time, the reciprocating plate 405 compresses the airbag 406, causing the air inside the airbag 406 to be forced into the discharge hopper 202 through the exhaust check valve 404. Meanwhile, the movable toothed plate 409 on the other side wall of the booster box 402 extends beyond the fixed toothed plate 412 due to the rotation of the inlet hopper 203. After the second gear 411 is engaged, the reciprocating plate 405 is reset by the pulling force of the second spring 407. At this time, the reciprocating plate 405 drives the airbag 406 to extend and draws air through the air inlet check valve 403. After the waste liquid enters the discharge hopper 202 through the fixed pipe 302, it is filtered through the filter layer 414. Then, air is introduced into the discharge hopper 202 through the air outlet check valve 404 to increase the pressure in the discharge hopper 202, assist the filtration speed in the discharge hopper 202, and improve the discharge speed of the waste liquid. The filter layer 414 can be replaced by rotating the discharge hopper 202 to detach it from the connecting pipe 201, making the replacement of the filter layer 414 simple and quick.

[0046] The filtered waste liquid enters the flow-limiting pipe 501. The adjusting plate 508 is rotated to drive the adjusting sleeve 507 to rotate, so that the adjusting sleeve 507 rotates on the threaded pipe 505. The threaded connection between the adjusting sleeve 507 and the threaded pipe 505 keeps the adjusting sleeve 507 stable. When the adjusting sleeve 507 rotates on the threaded pipe 505, it drives the adjusting rod 506 to rotate into the rod groove 504. The adjusting rod 506 engages with the rod groove 504, which drives the rotating shaft 502 to rotate at the same time. The rotating shaft 502 then drives the flow-limiting plate 503 to rotate. The discharge flow rate is adjusted by adjusting the gap between the flow-limiting plate 503 and the inner wall of the flow-limiting pipe 501.
