Abstract

The present invention belongs to the technical field of chemical treatment, and discloses a chemical wastewater treatment device with a solid-liquid separation function for high mud content, including a base. The upper surface of the base is fixedly installed with a housing, and a filtering mechanism is arranged inside the housing. Through the centrifugal force generated by the outer blades and inner blades rotating forward and backward, the wastewater and clear water of the chemical wastewater with high mud content are concentrated towards the middle of the outer blades and inner blades, slowing down the time for the water in the chemical wastewater with high mud content between the base mechanism and the feeding mechanism in the inner cavity of the inner shell to flow through the filter membrane towards the inner surface of the housing and the outer surface of the inner shell, providing sufficient time for the wastewater and clear water of the chemical wastewater with high mud content to be fully mixed, so that the wastewater and clear water of the chemical wastewater with high mud content are fully mixed, reducing the concentration of the chemical wastewater with high mud content, facilitating the separation of the chemical wastewater in the subsequent chemical wastewater with high mud content, and thus solving the problems of poor separation effect and high energy consumption of the existing chemical wastewater treatment device with high mud content.

Description

Technical Field

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

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

[0003] Currently, the 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 the chemical wastewater with high mud content, there will still be a large amount of chemical substances remaining in the mud, resulting in the need for a special area to fill the treated chemical mud in the later stage, which will not only increase the treatment cost, but also cause environmental pollution; in addition, when centrifugally separating chemical wastewater with high mud content, due to the large amount of mud in the chemical wastewater with high mud content, at the initial stage of separation, the motor needs to drive the chemical wastewater with high mud content to rotate with extremely high power for centrifugal separation. As the water content in the chemical wastewater with high mud content decreases, the difficulty of water separation increases continuously, and a high-speed motor is required to drive the separation of the chemical wastewater with high mud content. Therefore, when the device is produced, a high-power and high-speed motor needs to be provided, which will not only increase the production cost, but also increase unnecessary energy consumption, and is not conducive to actual energy-saving and environmental protection production.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. In the present invention, first, high-silt-content chemical wastewater and clean water are injected between the inner cavity of the inner housing, the base mechanism and the feeding mechanism, so that the base mechanism drives the support shaft mechanism to squeeze the elastic member and move downward until the bottom surface of the base mechanism contacts the upper surface of the mounting disc. At this time, the driving gear and the reversing wheel at the bottom of the support shaft mechanism contact and mesh with the medium gear with the smallest size at the bottom. Then, the speed-changing mechanism is started. The speed-changing mechanism drives the inner blades in the middle of the base mechanism to rotate forward through the support shaft mechanism, and the outer blades on the inner side of the housing mechanism rotate reversely. At this time, the reversely rotating outer blades and inner blades efficiently and quickly stir the high-silt-content chemical wastewater and clean water injected between the inner cavity of the inner housing, the base mechanism and the feeding mechanism. At the same time, the centrifugal force generated by the reversely rotating outer blades and inner blades causes the high-silt-content chemical wastewater and clean water to concentrate towards the middle of the outer blades and inner blades, slowing down the time for the water in the high-silt-content chemical wastewater between the inner cavity of the inner housing, the base mechanism and the feeding mechanism to flow through the filter membrane to the space between the inner curved surface of the outer housing and the outer curved surface of the inner housing, providing sufficient time for the high-silt-content chemical wastewater and clean water to be fully mixed, so that the high-silt-content chemical wastewater and clean water are fully mixed, reducing the concentration of the high-silt-content chemical wastewater, and facilitating the subsequent separation operation of the chemical wastewater in the high-silt-content chemical wastewater.

[0015] 2. As the moisture content in the chemical wastewater with mud in the inner cavity of the inner shell, the base mechanism, and the feeding mechanism continuously decreases under the action of the rotating inner blades and the filter membrane, the proportion of mud in the chemical wastewater with mud continuously increases. At this time, the resistance for the moisture in the chemical wastewater with mud to separate continuously increases. Meanwhile, the mass of the chemical wastewater with mud between the base mechanism and the feeding mechanism in the inner cavity of the inner shell continuously decreases. 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 upward-moving main gear alternately contacts and meshes with the medium gears with larger sizes, thereby continuously increasing the rotation speed of the main gear. The main gear drives the rotation speed of the main shaft to continuously increase, the main shaft drives the rotation speed of the inner ring to continuously increase, and the inner ring drives the rotation speed of the inner blades to continuously increase. The inner blades continuously increase the centrifugal force of the chemical wastewater with mud. Thus, when the moisture content in the chemical wastewater with mud is high, the mass is large, and the moisture is easily separated, while keeping the power of the driving member stable, the rotation speed of the base mechanism is reduced to effectively separate the mud from the wastewater. When the moisture content in the chemical wastewater with mud becomes less and the mass becomes smaller, making it difficult to separate the moisture, the rotation speed of the base mechanism is increased to effectively separate the mud from the wastewater, avoiding extreme changes in the power of the driving member, increasing the service life of the driving member, and at the same time avoiding the use of driving members with high power consumption and high rotation speed, reducing the manufacturing cost and energy consumption of the equipment.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 to 7 shown, the embodiment of the present invention provides a high-silt-content chemical wastewater treatment device with a solid-liquid separation function, including a base 1. The upper surface of the base 1 is fixedly installed with an outer shell 2. The filtration mechanism 3 includes a filtration ring 301. The filtration ring 301 is fixedly installed at the bottom of the inner curved surface of the outer shell 2. A plurality of conduits 302 are fixedly installed at equal intervals in the circumferential direction of the middle part of the filtration ring 301. The top ends of the conduits 302 are fixedly installed with a water pump 303. The inside of the outer shell 2 is provided with a filtration mechanism 3. An outer shell mechanism 4 is arranged between the outer shell 2 and the filtration mechanism 3. The outer shell mechanism 4 includes an inner shell 401. The inner shell 401 is movably sleeved in the middle of the inner cavity of the outer shell 2. The outer curved surface of the inner shell 401 is in sliding contact with the inner curved surface of the filtration ring 301. A plurality of side grooves are equidistantly arranged in the circumferential direction of the middle part of the curved surface of the inner shell 401. A filter membrane 402 is fixedly installed in the middle of each of the plurality of side grooves. The filter membrane 402 is made of a material that is permeable to water but impermeable to mud. The filter membrane 402 is made of non-woven fabric, so as to realize the filtration and separation of the chemical wastewater in the high-silt-content chemical wastewater. 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 prevent the chemical waste mud from concentrating and adhering in 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. At the same time, when the outer ring 703 moves up and down, it is convenient to scrape off the chemical waste mud adhering to the inner cavity of the inner shell 401 and the filter membrane 402. An inner gear 403 is fixedly installed at the bottom of the inner curved surface of the inner shell 401. A reversing wheel 404 is movably sleeved at the bottom of the inner cavity of the outer shell 2;

[0026] The internal gear 403 meshes with the reversing wheel 404. The inner curved surface of the inner shell 401 is movably sleeved with an installation disk 405. The upper surface of the installation disk 405 is on the same horizontal plane as the bottom surface of the side groove, thereby avoiding that when the upper surface of the installation disk 405 is lower than the bottom surface of the side groove, a small amount of chemical wastewater flows back and accumulates between the upper surface of the installation disk 405 and the bottom surface of the side groove in the inner cavity of the inner shell 401 through the filter membrane 402, causing the installation disk 405 to be corroded by chemical wastewater for a long time and reducing its lifespan. The elastic member 6 is fixedly installed in the middle of the upper surface of the installation disk 405. A plurality of outer blades 406 are fixedly installed at equal intervals on the outer circumference of the upper surface of the installation disk 405. The plurality of outer blades 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. A speed change mechanism 9 is provided between the bottom of the outer shell 2 and the support shaft mechanism 5.

[0027] As Figure 3 , Figure 4 and Figure 6 shown, the support shaft mechanism 5 includes a main shaft 501. The main shaft 501 is movably sleeved at the bottom of the outer shell 2. The main shaft 501 is movably sleeved in the middle of the installation disk 405. A top block 502 is fixedly installed at the top end of the inner cavity of the main shaft 501. A hydraulic rod 503 is fixedly installed at the bottom end of the top block 502. A piston 504 is fixedly installed at the telescopic end of the hydraulic rod 503. The curved surface of the piston 504 is provided with a rubber coating. The inner curved surface of the main shaft 501 is a smooth surface, thereby improving the sealing performance between the piston 504 and the main shaft 501 and avoiding that when the high-silt-content chemical wastewater between the inner cavity of the inner shell 401, the base mechanism 7 and the feeding mechanism 8 is stirred or separated, it flows into the inner cavity of the main shaft 501 through the contact gap between the piston 504 and the main shaft 501, causing leakage and polluting the treated sludge. A plurality of discharge holes 505 are equidistantly opened on the upper circumference of the curved surface of the main shaft 501. A main gear 506 is fixedly sleeved at the bottom of the curved surface of the main shaft 501.

[0028] As Figure 3 and Figure 7 shown, the base mechanism 7 includes an inner ring 701. The inner ring 701 is slidably installed at the top end of the elastic member 6. The inner ring 701 is fixedly sleeved with the main shaft 501. A plurality of inner blades 702 are fixedly installed at equal intervals on the upper surface of the inner ring 701. An outer ring 703 is slidably sleeved outside the inner ring 701. The contact surface between the outer ring 703 and the inner ring 701 is a smooth surface, thereby reducing the frictional resistance between the outer ring 703 and the inner ring 701 when the support shaft mechanism 5 drives the inner ring 701 to rotate and reducing the load of the driving member 901 in the speed change mechanism 9. The outer ring 703 is slidably sleeved with the outer blades 406.

[0029] As Figure 3 and Figure 7As shown in the figure, the feeding mechanism 8 includes a leakage ring 801. The leakage ring 801 is fixedly installed at the upper part of the inner curved surface of the inner shell 401. A chamfer is provided at the upper part of the inner cavity of the leakage ring 801. A plurality of square grooves are equidistantly arranged on the bottom circumference of the leakage ring 801. Elastic blocks 802 are fixedly installed on the top surfaces of the plurality of square grooves. A sealing ring 803 is fixedly installed at the bottom of the plurality of elastic blocks 802. Flexible rubber coatings are provided on the bottom surface of the leakage ring 801 and the upper surface of the sealing ring 803, so as to improve the sealing performance between the bottom surface of the leakage ring 801 and the upper surface of the sealing ring 803, overcome the problem that the sludge remaining on the upper surface of the sealing ring 803 causes the weakening of the sealing performance between the leakage ring 801 and the sealing ring 803, and at the same time avoid the problem that when the base mechanism 7 and the feeding mechanism 8 pressurize the sludge therebetween, part of the chemical wastewater flows above the leakage ring 801 through the leakage ring 801 and the sealing ring 803, resulting in a poor chemical sludge dewatering effect.

[0030] As Figure 2 , Figure 3 and Figure 5 shown in the figure, the speed change mechanism 9 includes a driving member 901. The driving member 901 is fixedly installed on the right side of the bottom surface of the outer shell 2. The output end of the driving member 901 is fixedly installed with a driving gear 902. A driven gear sleeve 903 is movably sleeved in the middle of the bottom surface of the outer shell 2. A plurality of tooth shafts 904 are movably sleeved on the bottom of the outer shell 2 at equal intervals along the circumferential direction. The distances from the plurality of tooth shafts 904 to the center of the outer shell 2 increase equidistantly in the counterclockwise direction. The top of the tooth shaft 904 is movably sleeved with a mounting disk 405. Connecting gears 905 are fixedly installed at the bottom ends of the plurality of tooth shafts 904. The connecting gears 905 are meshed with the driven gear sleeve 903. Medium gears 906 are fixedly sleeved on the curved surfaces of the plurality of tooth shafts 904. The height difference between two adjacent medium gears 906 is greater than or equal to the thickness of a main gear 506, so as to realize that when the main gear 506 moves upward or downward, the main gear 506 is only meshed with one of the medium gears 906 with the same height. The diameters of the plurality of medium gears 906 increase equidistantly in the counterclockwise direction, so as to realize that when the main gear 506 moves upward or downward, the medium gears 906 meshed with the main gear 506 increase or decrease in turn, so as to realize a uniform increase or decrease in the rotation speed of the main gear 506.

[0031] Working principle:

[0032] When the present invention is in use, first pour the chemical wastewater with high mud content into the upper part of the feeding mechanism 8 in the inner cavity of the inner shell 401. At this time, under the action of gravity, the chemical wastewater with high mud content pushes the sealing ring 803 downward, and the sealing ring 803 pulls the elastic block 802 to elongate. At this time, the chemical wastewater with high mud content flows into the space between the base mechanism 7 and the feeding mechanism 8 in the inner cavity of the inner shell 401 along the gap between the bottom surface of the leakage ring 801 and the upper surface of the sealing ring 803. Similarly, at the same time, pour a large amount of clean water into the upper part of the feeding mechanism 8 in the inner cavity of the inner shell 401 to reduce the sludge concentration in the chemical wastewater with high mud content between the inner cavity of the inner shell 401, the base mechanism 7 and the feeding mechanism 8. At this time, the chemical wastewater with low mud 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 blade 406, squeezing the elastic member 6 to contract and move downward. 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. 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 smallest middle gear 906 at the bottom;

[0033] At the same time, continue to inject the chemical wastewater with high mud content and clean water between the base mechanism 7 and the feeding mechanism 8 in the inner cavity of the inner shell 401 until the liquid levels of the chemical wastewater with high mud content and clean water fill up to two-thirds of the volume between the base mechanism 7 and the upper surface of the mounting plate 405, that is, when the inner cavity of the inner shell 401, the base mechanism 7 and the feeding mechanism 8 are filled, stop injecting the chemical wastewater with high mud content and clean water. At this time, the elastic block 802 resumes, and the elastic block 802 pulls the sealing ring 803 downward to fit tightly with the bottom surface of the leakage ring 801. The inner blade 702 moves downward to disengage from the sealing ring 803. Then start the driving member 901. The output shaft of the driving member 901 drives the driving gear 902 to rotate forward. The output shaft of the driving gear 902 drives the driven gear sleeve 903 to rotate forward. The driven gear sleeve 903 drives the connecting gear 905 to rotate forward. The connecting gear 905 drives the tooth shaft 904 to rotate forward. The tooth shaft 904 drives a plurality of middle gears 906 to rotate forward. At this time, since only the smallest middle gear 906 at the bottom contacts the main gear 506, the smallest middle gear 906 drives the main gear 506 to rotate forward. 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. 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 internal gear 403 to rotate reversely. The internal gear 403 drives the inner shell 401 to rotate reversely. The inner shell 401 drives the outer blade 406 to rotate reversely. The outer blade 406 drives the feeding mechanism 8 to rotate reversely. At this time, the reversely and forwardly rotating outer blade 406 and inner blade 702 efficiently and rapidly stir the chemical wastewater with high mud content and clean water injected between the inner cavity of the inner shell 401, the base mechanism 7 and the feeding mechanism 8;

[0034] The centrifugal forces generated by the outer blade 406 and the inner blade 702 rotating in opposite directions simultaneously cause the wastewater and clear water of high-silt-content chemical industry to concentrate towards the middle between the outer blade 406 and the inner blade 702, slowing down the time for the water in the high-silt-content chemical wastewater between the inner cavity base mechanism 7 of the inner shell 401 and the feeding mechanism 8 to flow through the filter membrane 402 towards the space between the inner curved surface of the outer shell 2 and the outer curved surface of the inner shell 401, providing sufficient time for the wastewater and clear water of high-silt-content chemical industry to mix fully, so that the wastewater and clear water of high-silt-content chemical industry are mixed fully, reducing the concentration of the high-silt-content chemical wastewater. While stirring, part of the liquid between the inner cavity base mechanism 7 of the inner shell 401 and the feeding mechanism 8 flows through the filter membrane 402 to the upper part of the filter ring 301 between the inner curved surface of the outer shell 2 and the outer surface of the inner shell 401, and after being filtered by the filter ring 301, it flows to the lower part of the filter ring 301 between the inner curved surface of the outer shell 2 and the outer surface of the inner shell 401;

[0035] As part of the liquid between the inner cavity base mechanism 7 of the inner shell 401 and the feeding mechanism 8 slowly drains away, the pressure above the base mechanism 7 decreases, and the elastic member 6 pushes the base mechanism 7 to move upward. The base mechanism 7 drives the main shaft 501 to move upward. When the wastewater and clear water of high-silt-content chemical industry between the inner cavity base mechanism 7 of the inner shell 401 and the feeding mechanism 8 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. The inner ring 701 drives the inner blade 702 to rotate. The centrifugal force generated by the inner blade 702 makes the high-silt-content chemical wastewater closely adhere to the filter membrane 402;

[0036] At this time, the wastewater containing chemical substances in the chemical wastewater with mud content flows through the filter membrane 402 to the space between the inner surface of the outer shell 2 and the outer surface of the inner shell 401. The mud remains between the base mechanism 7 and the feeding mechanism 8 in the inner cavity of the inner shell 401. As the moisture content in the chemical wastewater with mud content between the base mechanism 7 and the feeding mechanism 8 in the inner cavity of the inner shell 401 continuously decreases, the proportion of mud in the chemical wastewater with mud content continuously increases, and the resistance for the moisture in the chemical wastewater with mud content to separate continuously increases. At the same time, the mass of the chemical wastewater with mud content between the base mechanism 7 and the feeding mechanism 8 in the inner cavity of the inner shell 401 continuously decreases. At this time, the elastic member 6 continuously pushes the base mechanism 7 to move upward, the base mechanism 7 continuously drives the main shaft 501 to move upward, and the main shaft 501 continuously drives the main gear 506 to move upward. The upward moving main gear 506 alternately contacts and meshes with the medium gear 906 with a larger size, thereby continuously increasing the rotation speed of the main gear 506. 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, and the inner ring 701 drives the rotation speed of the inner blades 702 to continuously increase. The inner blades 702 continuously increase the centrifugal force of the chemical wastewater with mud content. Thus, when the moisture content in the chemical wastewater with mud content is high, the mass is large, and the moisture is easy to separate, while keeping the power of the driving member 901 stable, the rotation speed of the base mechanism 7 is reduced to effectively separate the mud from the wastewater. When the moisture content in the chemical wastewater with mud content becomes less, the mass becomes smaller, and it is difficult to separate the moisture, the rotation speed of the base mechanism 7 is increased to effectively separate the mud from the wastewater, avoiding extreme changes in the power of the driving member 901, increasing the service life of the driving member 901, and at the same time avoiding the use of a driving member 901 with high power consumption and high rotation speed, reducing the manufacturing cost and energy consumption of the equipment;

[0037] In addition, in the present invention, when the elastic member 6 pushes the base mechanism 7 upward until the base mechanism 7 pushes the chemical waste mud after the chemical wastewater is separated into contact with the bottom surface of the feeding mechanism 8, after the base mechanism 7 and the feeding mechanism 8 squeeze and further separate the remaining chemical wastewater in the chemical mud, similarly, cleaning is added to the chemical waste mud again, and sufficient moisture separation is carried out again until the chemical substances in the chemical waste mud are reduced to a reasonable range. Finally, the hydraulic rod 503 is started, and the telescopic end of the hydraulic rod 503 drives the piston 504 to move downward. The base mechanism 7 squeezes the final chemical waste mud downward and flows out of the device through the discharge hole 505 and the main shaft 501 for collection.
