Description

Technical Field

[0001] The invention belongs to the technical field of chemical treatment, and in particular relates to a high-mud content chemical wastewater treatment device with a solid-liquid separation function. Background Art

[0002] In the chemical production process, a large amount of wastewater containing high concentrations of suspended solids, colloids and dissolved organic matter is generated. These wastewaters not only contain high concentrations of pollutants, such as heavy metal ions, toxic organic compounds and various chemical residues, but are also often accompanied by high mud content, which brings great challenges to wastewater treatment. Traditional wastewater treatment technologies, such as coagulation sedimentation, biological treatment and filtration, can remove pollutants in wastewater to a certain extent, but when faced with chemical wastewater with high mud content, their treatment efficiency and stability are often greatly reduced.

[0003] Existing treatment of chemical wastewater with high mud content generally directly adopts extrusion or centrifugal separation. Although the extrusion method can remove most of the wastewater in chemical wastewater with high mud content, a large amount of chemical substances will still remain in the soil, resulting in the need for special areas to fill the chemical soil after later treatment, which will not only increase the treatment cost, but also cause environmental pollution; in addition, when centrifuging chemical wastewater with high mud content, due to the large mud content in chemical wastewater with high mud content, in the initial stage of separation, the motor needs extremely high power to drive the chemical wastewater with high mud content to rotate for centrifugal separation, and as the water content in chemical wastewater with high mud content decreases, the difficulty of water separation continues to increase, and a high-speed motor is required to drive the separation of chemical wastewater with high mud content. Therefore, when the device is produced, a high-power and high-speed motor is required, which will not only increase the production cost, but also increase unnecessary energy consumption, which is not conducive to actual energy-saving and environmentally friendly production.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention first injects high-mud-content chemical wastewater and clean water into the inner cavity of the inner shell, between the base mechanism and the feeding mechanism, so that the base mechanism drives the support shaft mechanism to squeeze the elastic member downward until the bottom surface of the base mechanism contacts the upper surface of the mounting plate. At this time, the main gear and the reversing wheel at the bottom of the support shaft mechanism are in contact and mesh with the middle gear with the smallest size at the bottom, and then the speed change mechanism is started. The speed change mechanism drives the inner leaf in the middle of the base mechanism to rotate forward through the support shaft mechanism, and the outer leaf on the inner side of the outer shell mechanism rotates reversely. At this time, the outer leaf and the inner leaf rotating forward and reversely rotate to inject high-mud-content chemical wastewater and clean water into the inner cavity of the inner shell, between the base mechanism and the feeding mechanism. The high-mud content chemical wastewater and clean water are stirred efficiently and quickly. At the same time, the centrifugal force generated by the positive and negative rotating outer and inner blades makes the high-mud content chemical wastewater and clean water concentrate in the middle of the outer and inner leaves, slowing down the time for the water in the high-mud content chemical wastewater to flow through the filter membrane to the inner curved surface of the outer shell and the outer curved surface of the inner shell between the inner shell inner cavity base mechanism and the feeding mechanism, providing enough time for the high-mud content chemical wastewater and clean water to be fully mixed, so that the high-mud content chemical wastewater and clean water are fully mixed, reducing the concentration of high-mud content chemical wastewater, and facilitating the subsequent separation operation of chemical wastewater in high-mud content chemical wastewater.

[0014] 2. In the present invention, as the moisture in the mud-containing chemical wastewater between the inner shell cavity, the base mechanism and the feeding mechanism is continuously reduced under the action of the rotating inner leaves and the filter membrane, the proportion of mud in the mud-containing chemical wastewater is continuously increasing. At this time, the resistance to the separation of moisture in the mud-containing chemical wastewater is continuously increasing. At the same time, the mass of the mud-containing chemical wastewater between the inner shell cavity base mechanism and the feeding mechanism is continuously reduced. At this time, the elastic member continuously pushes the base mechanism to move upward, the base mechanism continuously drives the main shaft to move upward, the main shaft continuously drives the main gear to move upward, and the main gear moving upward is alternately contacted and meshed with the larger middle gear, thereby continuously increasing the rotation speed of the main gear, and the main gear drives the rotation speed of the main shaft. The speed of the inner ring is continuously increasing, and the speed of the inner blade is continuously increasing driven by the main shaft. The inner ring drives the speed of the inner blade to continuously increase. The inner blade increases the centrifugal force of the chemical wastewater with mud content. Therefore, when the chemical wastewater with mud content has high water content, large mass and easy separation of water, the speed of the base mechanism is reduced while the power of the driving part remains stable, so as to achieve effective separation of mud and wastewater. When the water content in the chemical wastewater with mud becomes less and the mass becomes smaller, making it difficult to separate the water, the speed of the base mechanism is increased to achieve effective separation of mud and wastewater, avoid extreme changes in the power of the driving part, and increase the service life of the driving part. At the same time, it avoids the use of power-consuming and high-speed driving parts, and reduces the manufacturing cost and energy consumption of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of side grooves are provided, and filter membranes 402 are fixedly installed in the middle of the plurality of side grooves. The filter membranes 402 are made of water-permeable and mud-impermeable materials, and the filter membranes 402 are made of non-woven fabrics, so as to realize filtering and separation of chemical wastewater in chemical wastewater with high mud content. The inner curved surface of the filter membrane 402 and the inner curved surface of the inner shell 401 are on the same curved surface, so as to avoid the chemical waste mud from being concentrated and adhering to the gap formed by the inner curved surface of the filter membrane 402 and the inner curved surface of the inner shell 401, hindering the subsequent filtration of the filter membrane 402, and at the same time facilitating the outer ring 703 to move up and down, scraping off the chemical waste mud attached to the inner cavity of the inner shell 401 and the filter membrane 402, the bottom of the inner curved surface of the inner shell 401 is fixedly installed with an internal gear 403, and the bottom of the inner cavity of the outer shell 2 is movably sleeved with a reversing wheel 404; The inner gear 403 is meshed with the reversing wheel 404, and the inner curved surface of the inner shell 401 is movably sleeved with a mounting plate 405, and the upper surface of the mounting plate 405 is on the same horizontal plane as the bottom surface of the side groove, so as to avoid that when the upper surface of the mounting plate 405 is lower than the bottom surface of the side groove, a small amount of chemical wastewater flows back through the filter membrane 402 and accumulates between the upper surface of the mounting plate 405 in the inner cavity of the inner shell 401 and the bottom surface of the side groove, causing the mounting plate 405 to be corroded by the chemical wastewater for a long time and the service life is reduced. The elastic member 6 is fixedly installed in the middle of the upper surface of the mounting plate 405, and a plurality of outer leaves 406 are fixedly installed on the outer circumference of the upper surface of the mounting plate 405 at equal intervals, and the plurality of outer leaves 406 are fixedly connected to the inner curved surface of the inner shell 401. A support shaft mechanism 5 is provided in the middle of the outer shell 2 and the outer shell mechanism 4, an elastic member 6 is provided on the upper part of the outer shell mechanism 4, a base mechanism 7 is provided on the upper part of the elastic member 6, a feeding mechanism 8 is provided on the upper part of the base mechanism 7, and a speed change mechanism 9 is provided between the bottom of the outer shell 2 and the support shaft mechanism 5.

[0019] like Figure 3 , Figure 4 and Figure 6 As shown, the support shaft mechanism 5 includes a main shaft 501, which is movably sleeved on the bottom of the outer shell 2, and the main shaft 501 is movably sleeved on the middle part of the mounting plate 405. A top block 502 is fixedly installed on the top of the inner cavity of the main shaft 501, and a hydraulic rod 503 is fixedly installed on the bottom end of the top block 502. A piston 504 is fixedly installed on the telescopic end of the hydraulic rod 503. The curved surface of the piston 504 is provided with a rubber coating, and the inner curved surface of the main shaft 501 is a smooth surface, thereby improving the sealing between the piston 504 and the main shaft 501, and preventing chemical wastewater with high mud content from flowing into the inner cavity of the main shaft 501 through the contact gap between the piston 504 and the main shaft 501 during stirring or separation, causing leakage and polluting the treated sludge. Discharge holes 505 are equidistantly provided on the upper circumference of the curved surface of the main shaft 501, and a main gear 506 is fixedly sleeved on the bottom of the curved surface of the main shaft 501.

[0020] like Figure 3 and Figure 7 As shown, the base mechanism 7 includes an inner ring 701, which is slidably mounted on the top of the elastic member 6, and the inner ring 701 is fixedly sleeved with the main shaft 501. A plurality of inner leaves 702 are fixedly mounted at equal intervals on the upper surface of the inner ring 701. An outer ring 703 is slidably sleeved on the outer side of the inner ring 701. The contact surface between the outer ring 703 and the inner ring 701 is a smooth surface, thereby reducing the friction resistance between the outer ring 703 and the inner ring 701 when the support shaft mechanism 5 drives the inner ring 701 to rotate, reducing the load on the driving member 901 in the speed change mechanism 9, and the outer ring 703 is slidably sleeved with the outer leaves 406.

[0021] like Figure 3 and Figure 7As shown, the feeding mechanism 8 includes a leakage ring 801, which is fixedly mounted on the upper part of the inner curved surface of the inner shell 401, a chamfer is provided on the upper part of the inner cavity of the leakage ring 801, a plurality of square grooves are equidistantly provided on the bottom circumference of the leakage ring 801, elastic blocks 802 are fixedly mounted on the top surfaces of the plurality of square grooves, sealing rings 803 are fixedly mounted on the bottoms of the plurality of elastic blocks 802, and a flexible rubber coating is provided on the bottom surface of the leakage ring 801 and the upper surface of the sealing ring 803, thereby improving the sealing between the bottom surface of the leakage ring 801 and the upper surface of the sealing ring 803, overcoming the problem that the sealing between the leakage ring 801 and the sealing ring 803 is weakened due to the sludge remaining on the upper surface of the sealing ring 803, and at the same time avoiding the problem that when the base mechanism 7 and the feeding mechanism 8 pressurize the sludge between them, part of the chemical wastewater flows to the top of the leakage ring 801 through the leakage ring 801 and the sealing ring 803, thereby causing the dehydration effect of the chemical sludge to deteriorate.

[0022] like Figure 2 , Figure 3 and Figure 5 As shown, the speed change mechanism 9 includes a driving member 901, which is fixedly mounted on the right side of the bottom surface of the housing 2, a driving gear 902 is fixedly mounted on the output end of the driving member 901, a passive gear sleeve 903 is movably sleeved in the middle of the bottom surface of the housing 2, a plurality of gear shafts 904 are movably sleeved in the bottom of the housing 2 at equal intervals along the circumferential direction, the distances from the plurality of gear shafts 904 to the center of the housing 2 increase in equal intervals counterclockwise, the top of the gear shaft 904 is movably sleeved with the mounting plate 405, the bottom ends of the plurality of gear shafts 904 are all fixedly mounted with connecting gears 905, and the connecting gear 905 and the passive gear sleeve 903 mesh with each other The curved surfaces of the plurality of gear shafts 904 are all fixedly sleeved with middle gears 906, and the height difference between two adjacent middle gears 906 is greater than or equal to the thickness of one main gear 506, so that when the main gear 506 moves upward or downward, the main gear 506 only meshes with one of the middle gears 906 of the same height, and the right angles of the plurality of middle gears 906 increase equidistantly in a counterclockwise direction, so that when the main gear 506 moves upward or downward, the middle gears 906 meshing with the main gear 506 increase or decrease in sequence, thereby achieving a uniform increase or decrease in the rotation speed of the main gear 506.

[0023] Working principle: When the present invention is used, first pour the chemical wastewater with high mud content into the upper part of the feeding mechanism 8 of the inner cavity of the inner shell 401. At this time, the chemical wastewater with high mud content pushes the sealing ring 803 to move downward under the action of gravity, and the sealing ring 803 pulls the elastic block 802 to extend. At this time, the chemical wastewater with high mud content flows along the gap between the bottom surface of the leakage ring 801 and the upper surface of the sealing ring 803 into the inner cavity base mechanism 7 and the feeding mechanism 8 of the inner shell 401. Similarly, a large amount of clean water is poured into the upper part of the feeding mechanism 8 of the inner cavity of the inner shell 401 to reduce the inner cavity of the inner shell 401. , the concentration of sludge in the chemical wastewater with high sludge content between the base mechanism 7 and the feeding mechanism 8, at this time, the chemical wastewater with low sludge content above the base mechanism 7 pushes the base mechanism 7 to move downward along the inner curved surface of the inner shell 401 and the outer leaf 406 under the action of gravity, and squeezes the elastic member 6 to shrink and move downward, and at the same time, the base mechanism 7 drives the support shaft mechanism 5 to move downward until the bottom surface of the base mechanism 7 contacts the upper surface of the mounting plate 405, and at this time, the main gear 506 at the bottom of the support shaft mechanism 5 contacts and meshes with the reversing wheel 404 and the middle gear 906 with the smallest size at the bottom; At the same time, continue to inject high-mud content chemical wastewater and clean water into the space between the base mechanism 7 and the feeding mechanism 8 in the inner cavity of the inner shell 401 until the liquid level of the high-mud content chemical wastewater and clean water fills up to the contact between the base mechanism 7 and the upper surface of the mounting plate 405, and when the volume between the inner cavity of the inner shell 401, the base mechanism 7 and the feeding mechanism 8 accounts for two-thirds, stop injecting high-mud content chemical wastewater and clean water. At this time, the elastic block 802 is restored, and the elastic block 802 pulls the sealing ring 803 to move downward and fit tightly with the bottom surface of the leakage ring 801. The inner leaf 702 moves downward and disengages from the sealing ring 803. Then start the driving member 901. The output shaft of the driving member 901 drives the active gear 902 to rotate forward, and the output shaft of the active gear 902 drives the passive gear sleeve 903 to rotate forward, and the passive gear sleeve 903 drives the connecting gear 905 to rotate forward, and the connecting gear 905 drives the gear shaft 904 to rotate forward. The shaft 904 drives the multiple middle gears 906 to rotate forward. At this time, since only the smallest middle gear 906 at the bottom is in contact with the main gear 506, the smallest middle gear 906 drives the main gear 506 to rotate forward, and the main gear 506 drives the main shaft 501 to rotate forward. The main shaft 501 drives the inner ring 701 to rotate forward along the outer ring 703, and the inner blade 702 drives the inner blade 702 on its upper surface to rotate forward. The main gear 506 drives the reversing wheel 404 to rotate forward. At this time, under the action of the reversing wheel 404, the reversing wheel 404 drives the inner gear 403 to rotate reversely, the inner gear 403 drives the inner shell 401 to rotate reversely, the inner shell 401 drives the outer blade 406 to rotate reversely, and the outer blade 406 drives the feeding mechanism 8 to rotate reversely. At this time, the outer blade 406 and the inner blade 702 rotating forward and reversely efficiently and quickly stir the wastewater and clean water of the chemical industry with high mud content injected between the inner cavity of the inner shell 401, the base mechanism 7 and the feeding mechanism 8; The centrifugal force generated by the outer blades 406 and the inner blades 702 rotating forward and backward at the same time causes the wastewater and clean water of the chemical industry with high mud content to be concentrated in the middle of the outer blades 406 and the inner blades 702, slowing down the time for the water in the chemical wastewater with high mud content to flow between the inner base mechanism 7 of the inner shell 401 and the feeding mechanism 8 through the filter membrane 402 to the space between the inner curved surface of the outer shell 2 and the outer curved surface of the inner shell 401, providing enough time for the wastewater and clean water of the chemical industry with high mud content to be fully mixed, so that the wastewater and clean water of the chemical industry with high mud content are fully mixed, and the concentration of the chemical wastewater with high mud content is reduced. While stirring, part of the liquid of the inner base mechanism 7 of the inner shell 401 and the feeding mechanism 8 flows through the filter membrane 402 to the upper side of the filter ring 301 between the inner curved surface of the outer shell 2 and the outer side of the inner shell 401, and after being filtered by the filter ring 301, flows to the lower side of the filter ring 301 between the inner curved surface of the outer shell 2 and the outer side of the inner shell 401; As part of the liquid in the inner cavity base mechanism 7 and the feeding mechanism 8 of the inner shell 401 slowly drains away, the pressure above the base mechanism 7 decreases, the elastic member 6 pushes the base mechanism 7 to move upward, and the base mechanism 7 drives the main shaft 501 to move upward. When the high-mud content chemical wastewater and clean water between the inner cavity base mechanism 7 and the feeding mechanism 8 of the inner shell 401 are fully stirred and mixed, the main shaft 501 drives the main gear 506 to move upward and separate from the reversing wheel 404. At this time, the outer shell mechanism 4 stops rotating, and the main shaft 501 continues to drive the inner ring 701 to rotate, and the inner ring 701 drives the inner leaf 702 to rotate. The centrifugal force generated by the inner leaf 702 makes the concentrated mud content chemical wastewater fit closely with the filter membrane 402. At this time, the wastewater containing chemical substances in the mud-containing chemical wastewater flows through the filter membrane 402 to between the inner curved surface of the outer shell 2 and the outer curved surface of the inner shell 401, and the mud is retained between the inner cavity base mechanism 7 and the feeding mechanism 8 of the inner shell 401. As the water content in the mud-containing chemical wastewater between the inner cavity base mechanism 7 and the feeding mechanism 8 of the inner shell 401 continues to decrease, the proportion of mud in the mud-containing chemical wastewater continues to increase, and the resistance to the separation of water in the mud-containing chemical wastewater continues to increase. At the same time, the mass of the mud-containing chemical wastewater between the inner cavity base mechanism 7 and the feeding mechanism 8 of the inner shell 401 continues to decrease. At this time, the elastic member 6 continues to push the base mechanism 7 to move upward, the base mechanism 7 continues to drive the main shaft 501 to move upward, and the main shaft 501 continues to bring the main gear 506 to move upward. The main gear 506 moving upward alternately contacts and meshes with the larger middle gear 906, thereby making the main gear 506 move upward. The rotation speed of the wheel 506 is continuously increased, the main gear 506 drives the rotation speed of the main shaft 501 to continuously increase, the main shaft 501 drives the rotation speed of the inner ring 701 to continuously increase, the inner ring 701 drives the rotation speed of the inner blade 702 to continuously increase, and the inner blade 702 makes the centrifugal force of the mud-containing chemical wastewater continuously increase, so that when the water content of the mud-containing chemical wastewater is high, the mass is large and the water is easy to separate, the power of the driving member 901 is kept stable and unchanged, and the rotation speed of the base mechanism 7 is reduced to achieve effective separation of mud and wastewater. When the water content of the mud-containing chemical wastewater decreases and the mass decreases, making it difficult to separate the water, the rotation speed of the base mechanism 7 is increased to achieve effective separation of mud and wastewater, avoid extreme changes in the power of the driving member 901, and increase the service life of the driving member 901. At the same time, it is avoided to use the driving member 901 with high power consumption and high speed, thereby reducing the equipment manufacturing cost and energy consumption; In addition, in the present invention, when the elastic member 6 pushes the base mechanism 7 to move upward, the chemical waste mud after the chemical waste water is separated by the base mechanism 7 contacts the bottom surface of the feeding mechanism 8, and the base mechanism 7 and the feeding mechanism 8 squeeze the remaining chemical waste water in the chemical mud to continue to separate, similarly, the chemical waste mud is added for cleaning again, and the water is fully separated again until the chemical substances in the chemical waste mud are reduced to a position within a reasonable range, and finally the hydraulic rod 503 is started, and the telescopic end of the hydraulic rod 503 drives the piston 504 to move downward, and the base mechanism 7 squeezes the final chemical waste mud downward to be collected through the discharge hole 505 and the main shaft 501 outflow device.
