[0002] Before industrial wastewater is discharged, it needs to be purified to avoid polluting the environment and causing ecological problems. In addition to insoluble impurities and pollutants, the acidity or alkalinity of wastewater can also affect the environment, so it is necessary to neutralize the wastewater.

[0003] Existing wastewater pre-neutralization and conditioning devices lack a structure to clean up the salt crystals generated during wastewater neutralization. This causes salt crystals to accumulate in large quantities in the neutralization tank, filling it up and hindering the use of the device. Summary of the Invention

Therefore, this invention proposes an alkaline wastewater pre-neutralization and adjustment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An alkaline wastewater pre-neutralization and conditioning device includes a neutralization tank. A fixed plate is slidably connected inside the neutralization tank. Sliding blocks are fixedly connected to the left and right side walls of the fixed plate.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Reference Figures 1-4An alkaline wastewater pre-neutralization and conditioning device includes a neutralization tank 1. A fixed plate 3 is slidably connected inside the neutralization tank 1. Sliding blocks 4 are fixedly connected to the left and right side walls of the fixed plate 3. Sliding grooves 5 corresponding to the sliding blocks 4 are formed on the inner side wall of the neutralization tank 1. A crystallizing mesh 6 is arranged above the fixed plate 3. The size of the crystallizing mesh 6 corresponds to that of the neutralization tank 1. A fixed support 2 is fixedly connected to the top of the neutralization tank 1. A motor 10 is fixedly connected to the top of the fixed support 2. A rotating rod 11 is fixedly connected to the output end of the motor 10. The rotating rod 11 passes through the fixed support 2, the crystallizing mesh 6, and the fixed plate 3 and is rotatably connected to the lower inner wall of the neutralization tank 1. An adjustment structure is provided on the crystallizing mesh 6. A fixed scraper 24 is attached to the top of the crystallization mesh 6. The fixed scraper 24 is located on the front and rear sides of the rotating rod 11. Each fixed scraper 24 is equipped with a moving structure. As neutralization proceeds, acidic and alkaline substances react to form salt. Some of the salt will precipitate from the wastewater and crystallize on the crystallization mesh 6. The motor 10 is started, and the output end of the motor 10 drives the rotating rod 11 to rotate. Under the action of the adjusting structure, the entire crystallization mesh 6 moves upward to the outside of the neutralization tank 1. During the upward movement of the crystallization mesh 6, the moving structure will cause the fixed scraper 24 to move to both sides, scraping the crystals on the crystallization mesh 6 to the outside of the neutralization tank 1.

[0020] The adjustment structure includes a connecting bracket 18 fixedly connected to the top of the crystallizing mesh 6. Each connecting bracket 18 has an adjusting rod 19 fixedly connected to one end near the rotating rod 11. Each adjusting rod 19 has an adjusting sleeve 20 slidably fitted onto one end near the rotating rod 11. Each adjusting sleeve 20 has a threaded ring 21 fixedly connected to one end near the rotating rod 11. Each threaded ring 21 is semi-circular, and the rotating rod 11 has threads corresponding to the threaded ring 21. Each adjusting sleeve 20 has an adjusting cavity 22 inside. Each adjusting rod 19 extends through the inner wall of the corresponding adjusting sleeve 20 into the interior of the fixed bracket 2. Each adjusting rod 19 has an adjusting spring 23 fixedly connected to one end inside the adjusting cavity 22. 3. The ends away from the adjusting rod 19 are fixedly connected to the inner wall of the corresponding adjusting cavity 22. Each adjusting cavity 22 is fixedly provided with an electromagnet. Each adjusting rod 19 is embedded with a permanent magnet at one end inside the adjusting cavity 22. The permanent magnet and the electromagnet are mutually repelled. The electromagnet is provided with a matching controller. The controller can control the conduction and disconnection of the electromagnet. When the electromagnet is turned on, it repels the permanent magnet, causing the adjusting spring 23 to contract. The adjusting sleeve 20 and the threaded ring 21 move towards the rotating rod 11, causing the threaded ring 21 to move accordingly and engage with the rotating rod 11. Under the action of the thread, the threaded ring 21 moves up and down during the rotation of the rotating rod 11, thereby driving the entire crystallization mesh 6 to move upward.

[0021] Multiple fixing rods 7 are fixedly connected to the bottom of the crystallization mesh 6. Each fixing rod 7 passes through the fixing plate 3. A fixing block 8 is fixedly connected to the bottom of each fixing rod 7. A fixing spring 9 is fixedly connected to the top of each fixing block 8. The fixing spring 9 is sleeved on the outside of the corresponding fixing rod 7. The top of each fixing spring 9 is fixedly connected to the bottom wall of the fixing plate 3. An alarm is installed on the outer wall of the neutralization tank 1. The alarm and control button are existing devices. A control button is installed on each fixing plate 3. The control button corresponds to the alarm. As the number of crystals on the crystallization mesh 6 increases, the fixing spring 9 is stretched, and the crystallization mesh 6 moves downward relative to the fixing plate 3. Pressing the control button on the fixing plate 3 will trigger the alarm, so that the staff can clean the crystallization mesh 6 in time.

[0022] The movable structure includes mounting plates 12 fixedly connected to the upper end face of the fixed bracket 2 and the side wall of the fixed scraper 24. A mounting shaft 13 is rotatably connected between every two corresponding mounting plates 12. A connecting rod 14 is fixedly sleeved on the outer side of the upper mounting shaft 13, and a pushing rod 15 is fixedly sleeved on the outer side of the lower mounting shaft 13. Each connecting rod 14 has a connecting cavity 16 inside. Each pushing rod 15 extends through the lower inner wall of the corresponding connecting rod 14 into the connecting cavity 16, and the corresponding connecting rod 14 is slidably connected to the inner wall of the connecting cavity 16. As the crystallizing mesh 6 moves upward... During the process, the connecting rod 14 slides within the connecting cavity 16. When the connecting rod 14 slides to the end of the inner wall of the connecting cavity 16, the lengths of the connecting rod 14 and the push rod 15 can no longer change. The push rod 15 presses the connecting rod 14, causing it to move outward, which in turn moves the fixed scraper 24. Each mounting shaft 13 is fitted with a torsion spring. One end of each torsion spring is fixedly connected to the side wall of the corresponding mounting plate 12, and the end of each torsion spring away from the mounting plate 12 is fixedly connected to the side wall of the corresponding connecting rod 14 and the push rod 15, so that the mounting shaft 13 can return to its original position.

[0023] A stirring device 17 is slidably mounted on the part of the rotating rod 11 located below the fixed plate 3, and the stirring device 17 is rotatably connected to the bottom end of the fixed plate 3. The stirring device 17 is an existing device, and the stirring device 17 rotates together with the rotating rod 11 to stir the wastewater and accelerate the neutralization process.

[0024] In this invention, when the device is in use, the neutralizing agent is first poured into the neutralization tank 1. As neutralization proceeds, acidic and alkaline substances react to form salt. Some of the salt precipitates out of the wastewater and crystallizes on the crystallization mesh 6. As the number of crystals on the crystallization mesh 6 increases, the fixing spring 9 stretches, and the crystallization mesh 6 moves downward relative to the fixing plate 3. Pressing the control button on the fixing plate 3 activates the alarm, facilitating the cleaning of the crystallization mesh 6 by the staff. At this time, the motor 10 is started, and the output end of the motor 10 drives the rotating rod 11 to rotate. The controller activates the electromagnet, and the electromagnet and the permanent magnet repel each other, causing the adjusting spring 23 to contract. The adjusting sleeve 20 and the threaded ring 21 move towards the rotating rod 11. The movement causes the threaded ring 21 to move accordingly, engaging with the rotating rod 11. Under the action of the thread, as the rotating rod 11 rotates, the threaded ring 21 moves up and down, thereby driving the entire crystallizing mesh 6 upward to the outside of the neutralization tank 1. During the upward movement of the crystallizing mesh 6, the connecting rod 14 slides within the connecting cavity 16. When the connecting rod 14 slides to the end of the inner wall of the connecting cavity 16, the lengths of the connecting rod 14 and the pushing rod 15 can no longer change. The pushing rod 15 presses against the connecting rod 14, causing it to move outward, which in turn drives the fixed scraper 24 to move to both sides, scraping the crystals on the crystallizing mesh 6 outward to the outside of the neutralization tank 1.
