Description

Technical Field

[0001] The present invention relates to the technical field of chemical waste liquid filtration, and particularly relates to a high-efficiency waste liquid treatment device for chemical environmental protection. Background Art

[0002] During the chemical production process, a lot of chemical waste liquid will be generated. Due to the complex composition, direct discharge will pollute the environment. Therefore, flocculants or chemical agents will be added to sediment the waste liquid to remove impurities or heavy metal elements in the waste liquid, forming solid waste residues. Then, a filter net or a filter membrane will be used to filter the discharged waste liquid to intercept the solid waste residues. These solid waste residues will block the mesh holes of the filter net during filtration, resulting in a decrease in filtration efficiency. At the same time, as the solid waste residues increase, the anti-corrosion coating on the surface of the filter net will be damaged, causing the filter net to be gradually oxidized and corroded. Therefore, it is necessary to use a waste liquid treatment device to clean the filter net regularly.

[0003] The existing waste liquid treatment devices have many technical defects when in use. First, the filter net needs to be disassembled and replaced during cleaning, which is time-consuming and laborious and is not conducive to the development of a continuous waste liquid filtration process. Second, the cleaning methods of the filter net are usually cleaning or backwashing, and the two are carried out separately. Such cleaning methods lack linkage, have poor effects and low automation, resulting in low cleaning efficiency. Third, the current water flow speed and range for backwashing and cleaning the filter net are limited, resulting in low backwashing quality, serious waste of water resources and high use costs.

[0004] In summary, considering that the existing facilities cannot meet the working requirements, for this reason, we propose a high-efficiency waste liquid treatment device for chemical environmental protection. Summary of the Invention

[0024] The present invention provides a high - efficiency waste liquid treatment device for chemical industry environmental protection through improvement. Compared with the prior art, it has the following significant improvements and advantages: (1) Start the servo motor. Through a series of transmissions, the moving disc coaxial with the large gear rotates one week. The two driving columns on the moving disc perform circular motions, successively contacting and moving in the two driving wheel grooves, thereby generating a driving force to cause the entire elliptical special - shaped wheel to rotate 180°. As a result, the intermediate connecting seat coaxial with the elliptical special - shaped wheel rotates accordingly, and the filter meshes on the two through - slot filter seats are swapped in position. There is no need to disassemble and replace the filter mesh that needs to be cleaned, with a high degree of automation, saving time and effort, and enabling the filtration process to continue continuously.

[0025] (2) Start the hydraulic cylinder. The hydraulic rod extends upward. By using the two contact wheels on the contact wheel body to contact the wheel rail, the filter frame and the filter mesh are caused to flip upward. On the one hand, the filter frame and the filter mesh are in an inclined state, facilitating subsequent cleaning and adjusting the material - falling angle, with a high degree of automation. On the other hand, during the upward movement, the top of the filter frame will contact and squeeze several groups of curved spring steel sheets, causing the curved spring steel sheets to deform and vibrate repeatedly, hitting the filter frame at a high frequency, so that some of the blockages on the filter mesh are shaken off, achieving the purpose of automatic material shaking.

[0026] (3) Start the drive motor in the sliding seat. Through a series of transmissions, on the one hand, the walking gear coaxial with the first gear walks downward in the helical motion groove, and on the other hand, the cleaning roller coaxial with the first gear rotates. By using several groups of bristles to contact the filter mesh during the circular motion, and in cooperation with the shaking motion of the filter mesh (the two are inter - linked), the blockages in the mesh holes are cleaned, achieving the effect of cleaning while walking, with a high degree of automation and significantly improving the cleaning effect and efficiency.

[0027] (4) Relying on the power of the drive motor to save the power source, the sliding seat moves obliquely downward in the oblique movement groove and successively contacts the sliders on each air - bag air - compressing mechanism. The slider moves on a slope of the pressure track, and a relative acting force is generated between the two, causing the push rod to move horizontally, driving the pressing piece to continuously squeeze the cylindrical air - bag. The cylindrical air - bag is compressed, and the gas inside it is exported outward through the water supply pipe and directly enters the mixing cylinder at a high speed, mixing with water, increasing the water flow speed and dispersion degree, making the water flow impact force from the back - flushing nozzle greater and the flushing range wider, saving costs; the entire treatment device has a compact structure design, does not occupy space, and has a high degree of linkage between structures.

Specific embodiments

[0030] 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.

[0031] Embodiment 1 As Figures 1-9As shown in the figure, this embodiment provides a high-efficiency waste liquid treatment device for chemical environmental protection, including a device support 1. On one side of the top of the device support 1, a waste liquid reaction tank 2 is installed. The specific structure and size of the waste liquid reaction tank 2 can be designed according to actual situations. Inside the waste liquid reaction tank 2, a reaction tank 3 is provided. The bottom of the reaction tank 3 is inclined to facilitate centralized feeding. At the bottom of the reaction tank 3, a control pipe 4 is installed. A discharge valve is arranged in the control pipe 4. Right below the control pipe 4, a liquid receiving hopper 5 is provided. At the lower end of the liquid receiving hopper 5, a waste liquid discharge pipe 6 is installed.

[0032] Among them, the liquid receiving hopper 5 is fixedly connected to one end of a positioning platform 7 through an outer clamping sleeve 8. The outside of the outer clamping sleeve 8 is connected to a U-shaped baffle 80 fixed to the device support 1. The U-shaped baffle 80 plays a role in supporting and fixing. On both sides of the positioning platform 7, reinforcing ribs 81 are symmetrically welded, which play a role in connecting and fixing. One end of the reinforcing rib 81 away from the positioning platform 7 is welded to the inner wall of the device support 1, as Figure 2 shown.

[0033] Furthermore, a middle connecting seat 10 is rotatably arranged at the middle position inside the device support 1. On both sides of the middle connecting seat 10, slot-through filtering seats 11 are symmetrically arranged. Inside each group of slot-through filtering seats 11, a filtering frame 12 is movably arranged, as Figure 3 and 5 shown.

[0034] Among them, at the corners of the slot-through filtering seat 11, there are support blocks acting on the filtering frame 12, which play a supporting role to ensure the flatness of the horizontal placement of the filtering frame 12.

[0035] Among them, a filter screen 13 is installed on the filtering frame 12. One group of the filter screens 13 is located at the position between the control pipe 4 and the liquid receiving hopper 5, as Figure 2 、 3 and 5 shown.

[0036] In this embodiment, a large rotating shaft 14 is welded at the middle position of the upper end surface of the middle connecting seat 10. The upper end of the large rotating shaft 14 is fixedly connected to the inner side surface of the device support 1 through a positioning bearing seat 15. On both sides of the large rotating shaft 14, protective covers riveted to the device support 1 are symmetrically arranged, as Figure 3 and 5 shown.

[0037] In this embodiment, a small rotating shaft 16 is welded at the middle position of the lower end surface of the middle connecting seat 10. A middle bearing 17 is sleeved at the position where the small rotating shaft 16 contacts the positioning platform 7. The middle bearing 17 has a certain damping force. The small rotating shaft 16 rotates around the positioning platform 7. At the lower end of the small rotating shaft 16, an elliptical special-shaped wheel 18 is sleeved. Four groups of driving wheel grooves 19 are symmetrically opened on the elliptical special-shaped wheel 18, as Figure 3 and 5 shown.

[0038] Among them, the elliptical shaped wheel 18 is located on the upper end surface of the moving disc 21, and the two are in contact. A curved limiting plate 20 is arranged around the outer side surface of the moving disc 21, and the moving disc 21 moves around the curved limiting plate 20. The curved limiting plate 20 plays the role of limiting support to improve the movement stability of the moving disc 21. A collecting groove 24 is provided at the middle position of the upper end surface of the moving disc 21. Two groups of curved steps 22 that fit the elliptical shaped wheel 18 are symmetrically fixed at the edge of the upper end surface of the moving disc 21. A gap is formed between the two groups of curved steps 22 for the elliptical shaped wheel 18 to rotate and extend out. Two groups of driving columns 23 that interact with the driving wheel groove 19 are welded on the upper end surface of the moving disc 21. The driving column 23 moves in the driving wheel groove 19, and the two fit together, such as Figures 1-3 shown.

[0039] Furthermore, a support shaft 25 is vertically welded to the middle of the lower end surface of the moving disc 21, and a large bearing seat 26 is connected to the lower end of the support shaft 25. Figure 4 shown.

[0040] Among them, a large gear 27 is sleeved in the middle of the support shaft 25, and a small gear 28 is meshed on one side of the large gear 27. The small gear 28 is sleeved on the output shaft of the servo motor 29, and the servo motor 29 is vertically installed on the upper end surface of the large bearing seat 26, such as Figure 4 shown.

[0041] Furthermore, two groups of short shafts 30 are symmetrically welded to one end of each group of filter frames 12, and fixed bearings 31 for inserting the short shafts 30 are fixed on the inner wall of the through-slot filter seat 11. The filter frame 12 is flipped around the two groups of fixed bearings 31, and there is a feeding gap between the flipped filter screen 13 and the filter frame 12, such as Figure 5 and 6 shown.

[0042] Among them, a hydraulic cylinder 32 is vertically fixed to one end of the positioning platform 7 away from the outer ferrule 8, and a hydraulic rod 33 is movably provided inside the hydraulic cylinder 32 and extending upward. A wheel seat 34 is installed on the upper end of the hydraulic rod 33, and a contact wheel body 35 is rotatably provided in the wheel seat 34. Two groups of contact wheels 36 are symmetrically provided on the contact wheel body 35. Two groups of wheel rails 37 for the movement of the contact wheels 36 are installed on the filter frame 12 and on the back side of the filter screen 13. The wheel rails 37 extend from the filter frame 12, and the wheel rails 37 play a role in guiding the movement (the area of ​​the wheel rails 37 is small, and the filter area occupied can be ignored). Figure 5 and 6 shown.

[0043] Further, on one side of the top of the device support 1 away from the waste liquid reaction tank 2, two groups of side long seats 40 are symmetrically riveted. A back plate 41 for connecting the two groups of side long seats 40 is arranged on the device support 1. A cleaning area 42 is formed between the two groups of side long seats 40. The cleaning area 42 is located directly above the aggregate tank 24. The waste residue and waste liquid generated in the cleaning area 42 both enter the aggregate tank 24 downward, as Figure 1 and 7 shown.

[0044] Among them, a number of groups of riveting pieces 43 are equidistantly arranged on the back plate 41. A curved spring steel sheet 44 is welded on each group of riveting pieces 43. When the filter frame 12 rotates upward, it contacts the curved spring steel sheet 44, causing the curved spring steel sheet 44 to deform and vibrate. The curved spring steel sheet 44 is made of spring steel material and has the characteristics of deformation and vibration, as Figure 1 and 7 shown.

[0045] Among them, a cleaning roller 50 is rotatably arranged at the middle position of the cleaning area 42. Brush hairs 51 acting on the filter net 13 are evenly distributed on the outer surface of the cleaning roller 50. The softness and hardness of the brush hairs 51 are selected according to the actual situation. Cleaning shafts 52 are symmetrically welded at both ends of the cleaning roller 50, as Figures 7-9 shown.

[0046] Specifically, inclined tooth movement grooves 54 (with appropriate inclination) are opened on the inner side surfaces of the two groups of side long seats 40. The inclined tooth movement grooves 54 are parallel to the flipped filter frame 12. Rack teeth are equidistantly distributed at the bottom of the inclined tooth movement grooves 54. Traveling gears 53 acting on the rack teeth are sleeved on the cleaning shafts 52, as Figures 7-9 shown.

[0047] Further, an inclined movement groove 60 is opened in the inclined tooth movement groove 54 extending towards the inside of the side long seat 40. A sliding seat 55 is installed at the end of each cleaning shaft 52. The sliding seat 55 moves in the inclined movement groove 60. Slide bars 61 are symmetrically installed on the upper and lower surfaces of the sliding seat 55. Damping slide rails for the movement of the slide bars 61 are opened on the groove walls of the inclined movement groove 60. The damping slide rails have a certain damping force to overcome the movement tendency generated by the self - gravity of the entire cleaning roller structure, as Figures 7-9 shown.

[0048] Among them, a connecting inner bearing 56 is sleeved at the position where the cleaning shaft 52 contacts the inside of the sliding seat 55. One of the cleaning shafts 52 extends into the sliding seat 55 and sleeves a first - stage gear 62. A second - stage gear 63 is meshed with the upper end of the first - stage gear 62. The second - stage gear 63 is sleeved on the output shaft of the driving motor 64. The driving motor 64 is fixedly arranged through the outer side surface of the sliding seat 55, as Figure 8 and 9 shown.

[0049] In the use of this embodiment, first, the mixed waste liquid in the reaction tank 3 is flocculated or chemically reacted to precipitate. Then, the control valve on the control pipe 4 is opened, and all the waste liquid and mixture in the tank flow downward through the control pipe 4. When passing through the filter screen 13, the waste liquid penetrates through the filter screen 13 and drips into the liquid receiving hopper 5, where it is centrally collected and then discharged outward through the waste liquid discharge pipe 6. The flocculants or precipitates are intercepted on the upper end surface of the filter screen 13. At this time, the servo motor 29 is started to drive the small gear 28 to rotate. After meshing and decelerating, the large gear 27 is driven to rotate, causing the moving disk 21 coaxial with the large gear 27 to rotate one week. During this process, the two groups of driving columns 23 on the moving disk 21 perform circular motions and successively contact and move in the two groups of driving wheel grooves 19, thereby generating a driving force to cause the entire elliptical special-shaped wheel 18 to rotate 180° (from one wheel surface of the elliptical special-shaped wheel 18 being in contact with a group of curved step 22 to the other wheel surface of the elliptical special-shaped wheel 18 being in contact with the other group of curved step 22), so that the intermediate connecting seat 10 coaxial with the elliptical special-shaped wheel 18 rotates accordingly, and the filter screens 13 on the two groups of through-slot filter seats 11 are swapped (next, the filter screen 13 with clogged mesh holes is cleaned).

[0050] At this time, the hydraulic cylinder 32 is started, and the hydraulic rod 33 extends upward and enters the through-slot filter seat 11. By using the two groups of contact wheels 36 on the contact wheel body 35 to contact and move on the wheel rail 37, the filter frame 12 and the filter screen 13 are caused to turn upward around the two groups of fixed bearings 31. During the upward movement, the top of the filter frame 12 will contact and squeeze several groups of curved spring steel sheets 44 (the squeezing process can be repeated multiple times), causing the curved spring steel sheets 44 to deform and vibrate repeatedly, and hitting the filter frame 12 at a high frequency (during this process, there is an alternating process of contact and separation between the contact wheel 36 and the wheel rail 37), so that some of the blockages on the filter screen 13 are shaken off.

[0051] At the same time, the drive motor 64 in the sliding seat 55 is started to drive the second gear 63 to rotate, and through meshing, the first gear 62 is caused to rotate synchronously. On the one hand, the traveling gear 53 coaxial with the first gear 62 travels downward in the helical motion groove 54 (during this process, the slide bar 61 moves along the damping slide rail for limiting to ensure the stability of the traveling state of the traveling gear 53). On the other hand, the cleaning roller 50 coaxial with the first gear 62 rotates, and several groups of bristles 51 contact the filter screen 13 during the circular motion to clean the blockages in the mesh holes (cooperating with the shaking motion of the filter screen 13), achieving the effect of cleaning while traveling. The cleaned blockages are discharged from the blanking gap and fall into the aggregate groove 24 of the moving disk 21, where they are centrally collected.

[0052] Embodiment 2 On the basis of the first embodiment, the existing filter screen 13 generally assists in cleaning the blockages in the mesh holes by means of backwashing. However, the current speed and range of the backwashing water flow are limited, resulting in low backwashing quality and high usage costs. To solve the above technical problems, we have the following design, as Figures 10-13 shown.

[0053] Specifically, receiving grooves 82 are provided on the outer sides of both groups of side length seats 40. A water pressure tank 70 is placed in the receiving groove 82. A water outlet pipe 71 is connected to the lower end of the water pressure tank 70. A solenoid valve is installed on the water outlet pipe 71. One end of the water outlet pipe 71 away from the water pressure tank 70 is connected to a mixing cylinder 72. The mixing cylinder 72 is located inside the side length seat 40 near the back plate 41, as Figure 10 and 11 shown.

[0054] Among them, one end of the mixing cylinder 72 away from the water outlet pipe 71 is connected to a water supply telescopic hose 74. The water supply telescopic hose 74 can expand and contract with the linear movement of the water supply pipe 75. The end of the water supply telescopic hose 74 is connected to a water supply pipe 75. A backwashing spray head 76 is installed at the end of the water supply pipe 75. The backwashing spray head 76 acts on the back of the filter screen 13. The installation angle of the backwashing spray head 76 is designed according to the actual situation, as Figure 11 shown.

[0055] Furthermore, an outer pipe sleeve 79 is provided on the water supply pipe 75. The end of the outer pipe sleeve 79 is connected to a multi-stage push rod 78. The multi-stage push rod 78 extends horizontally outward from the inside of the push rod motor 77. The push rod motor 77 is horizontally installed inside the side length seat 40, as Figure 11 shown.

[0056] Furthermore, a porous joint 73 is installed at the upper end of the mixing cylinder 72. A check valve is provided on the porous joint 73. A number of gas supply pipes 86 are connected to the porous joint 73. The end of each group of gas supply pipes 86 is connected to an airbag air compression mechanism 9. The number of airbag air compression mechanisms 9 is distributed along the outer wall direction of the inclined movement groove 60 and is all on the movement path of the sliding seat 55, as Figure 11 shown.

[0057] Among them, pressure tracks 84 acting on each airbag air compression mechanism 9 are installed on the backs of both groups of sliding seats 55. Slopes 85 are symmetrically distributed inside the pressure tracks 84. The slopes 85 have a certain inclination, as Figure 13 shown.

[0058] Specifically, the airbag air compression mechanism 9 includes a partition plate 90, a push rod 91, a sliding head 92, a pressing piece 93, a return spring 94, an airbag limiting outer shell 95, a cylindrical airbag 96, a connecting rod 97, an airbag positioning plate 98 and an air inlet valve 99. The partition plate 90 is riveted inside the side length seat 40, as Figure 12As shown

[0059] In this embodiment, a rod hole for the movement of the push rod 91 is provided in the middle of the partition plate 90. The rod hole plays a role in limiting and guiding. One end of the push rod 91 is provided with a sliding head 92 extending into the pressure track 84 (the length that the sliding head 92 extends in the natural state is flush with the back surface of the sliding seat 55). The other end of the push rod 91 is installed with a pressing piece 93. A return spring 94 sleeved outside the push rod 91 is fixed between the pressing piece 93 and the partition plate 90. The partition plate 90 is horizontally connected with an airbag limiting housing 95 through two groups of connecting rods 97.

[0060] In this embodiment, a cylindrical airbag 96 is movably arranged inside the airbag limiting housing 95. The cylindrical airbag 96 is made of a rubber material with strong deformation and reset ability. One end of the cylindrical airbag 96 is in contact with the pressing piece 93. The other end of the cylindrical airbag 96 is fixedly connected with an airbag positioning plate 98. The airbag positioning plate 98 is connected with the airbag limiting housing 95. An air inlet valve 99 acting on the cylindrical airbag 96 is installed at the middle position of the bottom of the airbag positioning plate 98. The air inlet valve 99 is a one-way valve and automatically opens under the condition that the inside is in negative pressure. A connection hole for connecting the water supply pipe 86 is provided on the side surface of the airbag positioning plate 98. The water supply pipe 86 is communicated with the cylindrical airbag 96.

[0061] Wherein, an inner storage groove 83 for storing the water supply pipe 75 and the backwashing nozzle 76 is provided on the inner side surface of each side long seat 40, which plays a role of storage, as Figure 10 shown

[0062] Furthermore, a water filling port is provided at the upper end of the pressure water tank 70, and a pressure pump is installed inside the pressure water tank 70.

[0063] When this embodiment is in use, during the cleaning process of the filter screen 13, first start the push rod motors 77 in the side long seats 40 respectively. The multi-stage push rods 78 extend out, driving the water supply pipe 75 and the backwashing nozzle 76 to extend out from the inner storage groove 83, so that the two backwashing nozzles 76 are located at the middle position obliquely below the filter screen 13. At this time, make the pressure pump on the pressure water tank 70 work, press the water in the pressure water tank 70 into the water outlet pipe 71, and successively pass through the mixing cylinder 72, the water supply telescopic hose 74 and the water supply pipe 75, and spray out from the backwashing nozzle 76 to wash the back surface of the filter screen 13, cooperating with the work of the cleaning roller 50.

[0064] While the walking gear 53 is moving downward from top to bottom within the helical movement groove 54, the sliding seat 55 moves obliquely downward within the oblique movement groove 60. The sliding seat 55 will sequentially come into contact with the sliding heads 92 on each set of airbag air compression mechanisms 9. The sliding heads 92 move on a set of slopes 85 of the pressure track 84, and a relative force is generated between the two, causing the push rod 91 to move horizontally (the return spring 94 is continuously stretched), driving the pressing piece 93 to extend into the airbag limiting housing 95, continuously squeezing the cylindrical airbag 96, so that the cylindrical airbag 96 is compressed, and the gas inside it is exported outward through the air supply pipe 86 and directly enters the mixing cylinder 72 at a relatively high speed, mixing with water, increasing the water flow speed and dispersion degree, making the water flow impact force sprayed from the backwash nozzle 76 greater and the flushing range wider. When the sliding head 92 moves in the reverse direction on the other set of slopes 85 of the pressure track 84, under the return action of the return spring 94, the push rod 91 returns to its original position, and the cylindrical airbag 96 absorbs the outside air and returns to the inflated state.
