Description

Technical Field

[0001] The invention relates to the field of sewage treatment, and in particular to a sewage treatment device for water pollution control. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water area or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people. In the sewage treatment system that uses various inorganic coagulants and flocculants such as aluminum salts and iron salts, the sedimentation effect can also be significantly improved.

[0003] During the sewage treatment process, the flocculant and sewage are often mixed unevenly. First, when the existing sewage treatment device is in use, the stirring structure always has dead corners. During stirring, the top and bottom of the sewage cannot always be fully stirred. Secondly, when adding flocculants, the existing sewage treatment devices generally manually introduce the flocculants directly into the sewage. The flocculants always start to dissolve from the top of the sewage. In this case, it is difficult for the flocculants to be evenly mixed with the sewage, thereby affecting the sewage treatment effect. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the background technology and to propose a sewage treatment device for water pollution control.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A sewage treatment device for water pollution control comprises an outer shell, a driving motor is installed on the inner wall of the outer shell near the bottom, a winding roller is fixedly installed on the output shaft of the driving motor, an adjusting rope is wound on the outer wall of the winding roller, a connecting seat is fixedly installed on the end of the adjusting rope away from the winding roller, a plurality of connecting ropes are fixedly installed on the top of the connecting seat, a round table is fixedly installed between the ends of the plurality of connecting ropes away from the connecting seat, a plurality of stirring shafts are rotatably installed on the inner wall of the round table, a stirring rod is fixedly installed on the inner wall of the stirring shaft, a gear is fixedly installed on one end of the stirring shaft, a plurality of racks are fixedly installed on the inner wall of the outer shell, the teeth of the plurality of racks are respectively meshed with the teeth of a plurality of gears, and a spreading structure is fixedly installed on the outer wall of the round table.

[0007] In the above-mentioned sewage treatment device for water pollution control, the interior of the material spreading structure includes multiple sealing cylinders and multiple connecting plates, the sealing cylinders and connecting plates are fixedly installed on the top and side walls of the truncated cone respectively, an automatic telescopic rod is fixedly installed on the top of the connecting plate, an adjusting ring is fixedly installed between the tops of the multiple automatic telescopic rods, a plurality of hinged seats are fixedly installed on the inner side wall of the adjusting ring, a connecting shaft is hinged on the inner wall of the hinged seat, a material holding box is fixedly installed on the bottom of the connecting shaft, the multiple material holding boxes are respectively slidably connected to the multiple sealing cylinders, a plurality of material spreading windows are symmetrically provided on the outer wall of the material holding box, a plurality of material holding cavities are provided on the inner wall of the material holding box, a lifting plate is slidably connected to the inner wall of the material holding cavity, a plurality of elastic parts are evenly fixedly installed between the bottom of the lifting plate and the inner wall of the material holding cavity.

[0008] In the above-mentioned sewage treatment device for water pollution control, a plurality of mounting frames are fixedly mounted on the inner wall of the outer shell, a guide wheel is rotatably mounted on the inner wall of each mounting frame, and the inner walls of the plurality of guide wheels are rotatably connected to the outer walls of a plurality of connecting ropes respectively.

[0009] In the above-mentioned sewage treatment device for water pollution control, a protective box is fixedly installed at the bottom of the inner wall of the outer shell, the drive motor is fixedly installed on the inner wall of the protective box, and brackets are symmetrically fixedly installed at the bottom of the inner wall of the outer shell, and the winding roller is rotatably installed between the inner walls of the two brackets.

[0010] In the above-mentioned sewage treatment device for water pollution control, a plurality of vertical poles are fixedly installed on the bottom of the inner wall of the shell, and the outer walls of the plurality of vertical poles are slidably connected to the inner wall of the truncated cone.

[0011] In the above-mentioned sewage treatment device for water pollution control, a sewage outlet is fixedly installed on the inner wall of the shell near the bottom, a sewage outlet valve is fixedly installed on the outer wall of the sewage outlet, and a water injection port is fixedly installed on the inner wall of the shell near the top.

[0012] In the above-mentioned sewage treatment device for water pollution control, a base is fixedly installed on the bottom of the shell.

[0013] In the above-mentioned sewage treatment device for water pollution control, a counterweight ring is fixedly installed on the bottom of the truncated table, and the inner wall of the counterweight ring is slidably connected to the outer wall of the vertical rod.

[0014] Compared with the existing technology, the advantages of this sewage treatment device for water pollution control are:

[0015] 1. When the sewage is stirred, the driving motor is started, and the driving motor drives the winding roller to rotate back and forth. When the winding roller rotates back and forth, the adjusting rope is retracted and released back and forth. When the adjusting rope is retracted and released, the round table is pulled up and down by the connecting seat and the connecting rope. When the round table moves up and down, the gear also moves up and down. Because the gear and the rack are in meshing state, the gear drives the stirring shaft to rotate, and then the stirring rod stirs the sewage. The stirring shaft can move up and down inside the shell, so that any position of the sewage can be stirred, preventing the occurrence of stirring dead corners, making the stirring effect better, and the flocculant can be better mixed with the sewage;

[0016] 2. When it is necessary to add flocculants, put an appropriate amount of flocculants into the material chamber of each material box, drive the material box to move to a suitable position through the driving motor, and then start the automatic telescopic rod to extend. The automatic telescopic rod will push the adjustment ring to move upward, and the adjustment ring will drive the material box to slide out of the sealing cylinder at the hinge seat and the connecting shaft. When a spreading window is moved out, the flocculants in the corresponding material chamber will be scattered from the spreading window. When the flocculants are completely scattered, the position of the material box is adjusted again by the driving motor and the above steps are repeated. The flocculants can be sprinkled again at another position, thereby achieving the effect of evenly sprinkling the flocculants at any position and multiple positions, so that the flocculants can be fully mixed with the sewage;

[0017] 3. By controlling the amount of flocculant added in each material chamber, the amount of flocculant used can be effectively controlled when adding flocculants, thereby avoiding poor sewage treatment effect caused by less flocculant use, and preventing waste and environmental pollution caused by a large amount of flocculant added;

[0018] 4. When the flocculant is put in, when the material box reaches the appropriate position and starts to put in the flocculant, the driving motor will quickly reciprocate to make the material box move up and down quickly, so that the flocculant inside can be quickly dispersed. When the material box moves up and down, the elastic part will reciprocate and expand due to the action of inertia, thereby driving the lifting plate to jump quickly, and the flocculant can be ejected through the lifting plate, which can accelerate the dispersion of the flocculant on the one hand and prevent the flocculant from remaining on the other hand;

[0019] 5. In the present invention, the stirring rod is close to the material box. When the material box moves up and down to release the flocculant, the stirring rod will rotate back and forth to stir the released flocculant, thereby accelerating the mixing efficiency of the flocculant and sewage and improving the sewage treatment effect.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] Reference Figure 1-9 A sewage treatment device for water pollution control comprises a shell 1, a driving motor 2 is installed on the inner wall of the shell 1 near the bottom, a winding roller 3 is fixedly installed on the output shaft of the driving motor 2, an adjusting rope 4 is wound around the outer wall of the winding roller 3, a connecting seat 5 is fixedly installed on the end of the adjusting rope 4 away from the winding roller 3, a plurality of connecting ropes 6 are fixedly installed on the top of the connecting seat 5, a round table 7 is fixedly installed between the ends of the plurality of connecting ropes 6 away from the connecting seat 5, a plurality of stirring shafts 8 are rotatably installed on the inner wall of the round table 7, a stirring rod 9 is fixedly installed on the inner wall of the stirring shaft 8, a gear 10 is fixedly installed on one end of the stirring shaft 8, a plurality of racks 11 are fixedly installed on the inner wall of the shell 1, the teeth of the plurality of racks 11 are respectively meshed with the teeth of the plurality of gears 10, and a spreading structure 12 is fixedly installed on the outer wall of the round table 7.

[0033] In this embodiment, during the sewage treatment process, when the sewage needs to be stirred, the drive motor 2 is started, and the drive motor 2 drives the winding roller 3 to rotate reciprocatingly. When the winding roller 3 rotates reciprocatingly, the adjusting rope 4 will be reciprocated and released. When the adjusting rope 4 is retracted and released, it will pull the truncated table 7 to move up and down through the connecting seat 5 and the connecting rope 6. When the truncated table 7 moves up and down, the gear 10 will also move up and down. Because the gear 10 and the rack 11 are in a meshing state, the gear 10 will drive the stirring shaft 8 to rotate, and then the stirring rod 9 will stir the sewage. The stirring shaft 8 can move up and down inside the outer shell 1, so that any position of the sewage can be stirred, preventing the occurrence of stirring dead corners, making the stirring effect better, and the flocculant can be better mixed with the sewage.

[0034] Specifically, the interior of the material spreading structure 12 includes a plurality of sealing cylinders 1201 and a plurality of connecting plates 1202, the sealing cylinders 1201 and the connecting plates 1202 are respectively fixedly mounted on the top and side walls of the truncated table 7, an automatic telescopic rod 1203 is fixedly mounted on the top of the connecting plate 1202, an adjusting ring 1204 is fixedly mounted between the tops of the plurality of automatic telescopic rods 1203, a plurality of articulated seats 1205 are fixedly mounted on the inner side wall of the adjusting ring 1204, and a connecting shaft 1205 is hingedly mounted on the inner wall of the articulated seat 1205. 206, a material containing box 1207 is fixedly installed at the bottom of the connecting shaft 1206, and the multiple material containing boxes 1207 are slidably connected to the multiple sealing tubes 1201 respectively. The outer wall of the material containing box 1207 is symmetrically provided with multiple material spreading windows 1208, and the inner wall of the material containing box 1207 is provided with multiple material containing cavities 1209. The inner wall of the material containing cavity 1209 is slidably connected with a lifting plate 1210, and multiple elastic members 1211 are evenly and fixedly installed between the bottom of the lifting plate 1210 and the inner wall of the material containing cavity 1209.

[0035] In this embodiment, when it is necessary to add flocculants, a proper amount of flocculants is put into the material holding chamber 1209 in each material holding box 1207, and the material holding box 1207 is driven to move to a suitable position by the driving motor 2, and then the automatic telescopic rod 1203 is started to extend, and the automatic telescopic rod 1203 will push the adjustment ring 1204 to move upward, and the adjustment ring 1204 will drive the material holding box 1207 to slide out of the sealing cylinder 1201 at the hinge seat 1205 and the connecting shaft 1206. When the flocculant is removed, the flocculant in the corresponding material chamber 1209 will be scattered from the material spreading window 1208. After the flocculant is completely scattered, the position of the material box 1207 is adjusted by the driving motor 2 again and the above steps are repeated. The flocculant can be sprinkled again at another position, thereby achieving the effect of evenly sprinkling the flocculant at any position and multiple positions, so that the flocculant can be better mixed with the sewage. By controlling the amount of flocculant added in each material chamber 1209, the flocculant can be effectively controlled when adding the flocculant. The material used can avoid the poor sewage treatment effect caused by the small amount of flocculant used, and at the same time prevent the waste and environmental pollution caused by the large amount of flocculant added. When the flocculant is added, when the material box 1207 reaches the appropriate position and starts the flocculant addition work, the driving motor 2 will rotate back and forth quickly, so that the material box 1207 moves up and down quickly, so that the internal flocculant can be quickly dispersed. When the material box 1207 moves up and down, the elastic member 1211 will reciprocate and retract due to the action of inertia, thereby driving the lifting plate 1210 to jump quickly, and the flocculant can be ejected through the lifting plate 1210. On the one hand, the dispersion of the flocculant is accelerated, and on the other hand, the flocculant residue is prevented. In the present invention, the stirring rod 9 is close to the material box 1207. When the material box 1207 moves up and down to add flocculant, the stirring rod 9 will rotate back and forth to stir the added flocculant, thereby accelerating the mixing efficiency of the flocculant and sewage and improving the sewage treatment effect.

[0036] Specifically, a plurality of mounting frames 13 are fixedly mounted on the inner wall of the housing 1 , a guide wheel 14 is rotatably mounted on the inner wall of each mounting frame 13 , and the inner walls of the plurality of guide wheels 14 are rotatably connected to the outer walls of the plurality of connecting ropes 6 .

[0037] In this embodiment, the mounting frame 13 is used to install the guide wheel 14 and determine the position of the guide wheel 14. The guide wheel 14 can ensure that the connecting rope 6 moves along a predetermined trajectory and prevent the connecting rope 6 from deviating from the predetermined track or path during movement. The guiding effect makes the connecting rope 6 more stable during movement, thereby improving the efficiency and reliability of the entire mechanical system.

[0038] Specifically, a protection box 15 is fixedly installed at the bottom of the inner wall of the shell 1, the drive motor 2 is fixedly installed on the inner wall of the protection box 15, and brackets 16 are symmetrically fixedly installed at the bottom of the inner wall of the shell 1. The winding roller 3 is rotatably installed between the inner walls of the two brackets 16.

[0039] In this embodiment, the drive motor 2 is installed inside the protective box 15, and the protective box 15 seals the drive motor 2 to prevent sewage from damaging the drive motor 2 and ensure the normal operation of the equipment. The bracket 16 is used to support the winding roller 3 to increase the stability of the winding roller 3.

[0040] Specifically, a plurality of vertical rods 17 are fixedly mounted on the bottom of the inner wall of the housing 1 , and the outer walls of the plurality of vertical rods 17 are slidably connected to the inner wall of the truncated table 7 .

[0041] In this embodiment, the vertical rod 17 limits the truncated platform 7 so that the truncated platform 7 can only move in the vertical direction, thereby preventing the truncated platform 7 from deviating from the predetermined track.

[0042] Specifically, a sewage outlet 18 is fixedly installed on the inner wall of the housing 1 near the bottom, a sewage outlet valve 19 is fixedly installed on the outer wall of the sewage outlet 18, and a water injection port 20 is fixedly installed on the inner wall of the housing 1 near the top.

[0043] In this embodiment, when sewage discharge is required, the sewage valve 19 is opened to make the sewage outlet 18 unobstructed, and the residues after sewage treatment in the shell 1 can be discharged through the sewage outlet 18, and the sewage to be treated can be injected into the interior of the shell 1 through the water injection port 20.

[0044] Specifically, a base 21 is fixedly mounted on the bottom of the housing 1 .

[0045] In this embodiment, the provision of the base 21 increases the contact area between the device and the ground, increases the overall stability of the device, and prevents the device from sliding or tipping over, thereby protecting the safety of workers and the device itself.

[0046] Specifically, a counterweight ring 22 is fixedly mounted on the bottom of the truncated table 7 , and the inner wall of the counterweight ring 22 is slidably connected to the outer wall of the vertical pole 17 .

[0047] In this embodiment, the weight of the round table 7 is increased by providing the counterweight ring 22, thereby ensuring that the round table 7 can stably move up and down when the adjustment rope 4 is retracted and released, thereby increasing the stability of the device during operation.

[0048] The working principle and use process of the present invention are as follows: when in use, the sewage to be treated is injected into the interior of the housing 1 through the water injection port 20 to treat the sewage. During the sewage treatment process, when the sewage needs to be stirred, the drive motor 2 is started, and the drive motor 2 drives the winding roller 3 to rotate back and forth. When the winding roller 3 rotates back and forth, the adjusting rope 4 is retracted and released back and forth. When the adjusting rope 4 is retracted and released, it pulls the round table 7 to move up and down through the connecting seat 5 and the connecting rope 6. When the round table 7 moves up and down, the gear 10 will also move up and down with it. Because the gear 10 is in a meshing state with the rack 11, the gear 10 will drive the stirring shaft 8 to rotate, and then the stirring rod 9 will stir the sewage, and the stirring shaft 8 can move up and down inside the shell 1, so that any position of the sewage can be stirred to prevent the occurrence of stirring dead corners, so that the stirring effect is better, and the flocculant can be better mixed with the sewage. When the flocculant needs to be added, the flocculant is put into the material cavity 1209 in each material box 1207 in an appropriate amount, and the material box 1207 is driven to move to a suitable position by the driving motor 2, and then the automatic telescopic rod 1203 is started to extend, and the automatic telescopic rod 1203 will push the adjusting ring 1204 to move upward, and the adjusting ring 1204 will drive the material box 1207 to slide out of the sealing tube 1201 at the hinge seat 1205 and the connecting shaft 1206. When a material spreading window 1208 is moved out, it is located in the corresponding material cavity 1209. The flocculant will be scattered from the material spreading window 1208. After the flocculant is completely scattered, the position of the material box 1207 is adjusted by the driving motor 2 again and the above steps are repeated. The flocculant can be sprinkled again at another position, thereby achieving the effect of uniformly sprinkling the flocculant at any position and multiple positions, so that the flocculant can be better mixed with the sewage. By controlling the amount of flocculant added in each material holding chamber 1209, the amount of flocculant can be effectively controlled when the flocculant is added, thereby avoiding the poor sewage treatment effect caused by a small amount of flocculant, and preventing the waste and environmental pollution caused by a large amount of flocculant. When the flocculant is added, when the material box 1207 reaches the appropriate position and starts the flocculant addition work , the driving motor 2 will rotate back and forth rapidly, causing the material box 1207 to move up and down rapidly, so that the flocculant inside can be dispersed quickly. When the material box 1207 moves up and down, the elastic member 1211 will reciprocate and expand due to the action of inertia, thereby driving the lifting plate 1210 to jump rapidly, and the flocculant can be ejected through the lifting plate 1210, which on the one hand accelerates the dispersion of the flocculant, and on the other hand prevents the flocculant from remaining. In the present invention, the stirring rod 9 is close to the material box 1207. When the material box 1207 moves up and down to release the flocculant, the stirring rod 9 will rotate back and forth to stir the released flocculant, thereby accelerating the mixing efficiency of the flocculant and sewage and improving the sewage treatment effect.

[0049] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0050] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
