[0014] Compared with the prior art, the beneficial effects of this application are: (1) The present invention proposes a dosing device for sewage treatment, which is provided with a box body, a supporting base, a feed pipe, a discharge pipe, a rotating shaft, a rotating motor, a dosing pipe, a spray pipe, a mounting seat, a mounting plate, a material receiving assembly, a centrifugal assembly, an opening and closing assembly and a transmission assembly. After the liquid medicine is pumped into the spray pipe by an external liquid pump, the piston is driven to move by pressure to open the spray port for spraying. The rotating shaft is driven by the rotating motor to rotate, and the stirring rod, the connecting rod and the material receiving assembly rotate with the rotating shaft to perform horizontal stirring. The material receiving assembly, the transmission assembly and the opening and closing assembly are used to make the material receiving assembly rotate to a specific position to receive and discharge the material. Part of the liquid medicine falls on the surface of the sewage, and part of the liquid medicine is mixed with the inside of the sewage, thereby realizing the transportation of the liquid medicine from the top layer to the deep layer of the sewage.

[0015] (2) The present invention proposes a dosing device for sewage treatment, which is provided with a piston, a mounting ring 1, a buffer spring 1, a mounting ring 2, a counterweight block and a connecting rod 2.

The rotating shaft is driven by a rotating motor to rotate. The rotating shaft speed can be adjusted according to the sewage impurity concentration.

[0030] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0031] One of the preferred embodiments of the present application is as follows: Figures 1 to 10 As shown, a dosing device for sewage treatment comprises: a box body 1, a support base 8 is fixedly installed at an equal distance on the edge of the bottom outer wall of the box body 1, a feed pipe 9 is fixedly installed on the top outer wall of the box body 1, and a discharge pipe 10 is fixedly installed on the bottom outer wall of one side of the box body 1, and also comprises: a rotating shaft 11, a rotating motor 12, a dosing pipe 13, a spraying pipe 14, a mounting seat 16, a mounting plate 17, a material receiving assembly, a centrifugal assembly, an opening and closing assembly and a transmission assembly; the rotating shaft 11 is vertically arranged in the box body 1, and the bottom of the rotating shaft 11 is rotatably installed at the center position of the bottom inner wall of the box body 1; the rotating motor 12 is fixedly installed on the bottom outer wall of the box body 1, and the output shaft of the rotating motor 12 is fixedly connected to the rotating shaft 11; the dosing pipe 13 is vertically arranged, and the bottom of the dosing pipe 13 is fixedly installed on the top of the rotating shaft 11, and the top of the dosing pipe 13 passes through the top of the box body 1; there are two spraying pipes 14, and the two spraying pipes 14 are respectively fixedly installed horizontally on the dosing pipe 13 The bottom outer walls on both sides of the two medicine spraying pipes 14 are equidistantly provided with a plurality of medicine spraying ports at the bottom of the ends close to each other; the mounting seat 16 is fixedly mounted at the middle position of the circumference of the rotating shaft 11; there are two mounting plates 17, and the two mounting plates 17 are rotatably mounted on the outer walls of both sides of the mounting seat 16 through the connecting shaft on the sides of the two mounting plates 16, and a plurality of connecting rods 18 are distributed in a circular array on the mounting plate 17; there are a plurality of groups of material receiving components, and the plurality of groups of material receiving components are respectively mounted on the ends of the corresponding connecting rods 18 away from the mounting plate 17, so as to collect the medicine sprayed from the medicine spraying ports; there are two groups of centrifugal components, and the two groups of centrifugal components are respectively arranged in the corresponding medicine spraying pipes 14; there are two groups of opening and closing components, and the two groups of opening and closing components are respectively mounted on the top and bottom of the rotating shaft 11, so as to drive the opening and closing of the material receiving components; the transmission component is arranged between the bottom inner wall of the box body 1 and the two mounting plates 17, so as to drive the two mounting plates 17 to rotate in the vertical direction.

[0032] First, the top of the dosing tube 13 is connected to the external dosing source through a liquid pump, and the sewage to be treated is added through the feed pipe 9. Then, after the liquid medicine is pumped into the spraying tube 14 by the external liquid pump, the piston 201 is driven by pressure to move, and the spraying port is opened to spray medicine. Part of the liquid medicine falls on the surface of the sewage, and the rotating motor 12 is started to drive the rotating shaft 11 to rotate. The two groups of centrifugal components assist in adjusting the number of spraying ports through which the liquid medicine can pass according to the change in the rotation speed of the rotating shaft 11. If the impurity concentration of the sewage to be treated is too high, the rotation speed of the rotating shaft 11 is accelerated. If the impurity concentration of the sewage to be treated is too low, the rotation speed of the rotating shaft 11 is reduced. At the same time, a plurality of connecting rods 18 and material receiving components move with the rotating shaft 1 1 rotates to stir the sewage in the box body 1 horizontally, and the material receiving component collects the liquid medicine sprayed from the spray port as the mounting plate 17 rotates. The transmission component causes the two mounting plates 17 to rotate in the vertical direction while revolving with the rotating shaft 11. The two sets of opening and closing components automatically control the opening and closing of the material receiving component according to the position of the material receiving component, so that the material receiving component is opened when receiving materials at the top and at the bottom of the sewage, and closed at other positions, so that the liquid medicine is evenly mixed with the deep layer of the sewage, and part of the liquid medicine is mixed into the sewage. The treated water is discharged from the discharge pipe 10, realizing the transportation of the liquid medicine from the top layer to the deep layer of the sewage. At the same time, the horizontal stirring promotes the sewage and the liquid medicine to mix evenly, fully react with the sewage, and improve the sewage treatment effect.

[0033] For further reference, Figure 3 and Figure 5 The centrifugal assembly includes: a piston 201, a mounting ring 202, a buffer spring 203, a mounting ring 204, a counterweight 205 and a connecting rod 206. The piston 201 is slidably arranged in the spray pipe 14 at one end close to the dosing pipe 13, the mounting ring 202 is fixedly installed in the middle position of the circumferential inner wall of the spray pipe 14, the buffer spring 203 is fixedly installed between the mounting ring 202 and the piston 201, the mounting ring 204 is fixedly installed at one end of the spray pipe 14 away from the dosing pipe 13, the counterweight 205 is arranged in the spray pipe 14, the counterweight 205 is located between the mounting ring 202 and the mounting ring 204, and the connecting rod 206 is fixedly installed in the middle position between the counterweight 205 and the piston 201.

[0034] The rotating motor 12 is started to drive the rotating shaft 11 to rotate. If the impurity concentration of the sewage to be treated is too high, the rotation speed of the rotating shaft 11 is accelerated. If the impurity concentration of the sewage to be treated is too low, the rotation speed of the rotating shaft 11 is reduced. When the rotating shaft 11 rotates, the counterweight block 205 moves in the direction away from the rotating shaft 11 due to the centrifugal force. The movement of the counterweight block 205 will pull the connecting rod 206, thereby driving the piston 201 to move. As the speed of the rotating shaft 11 increases, the centrifugal force on the counterweight block 205 increases, so that the centrifugal pulling force of the counterweight block 205 assists the movement of the piston, so that more spray ports are connected to the inside of the spray pipe 14, and the number of spray ports through which the liquid medicine can pass is adjusted. The liquid medicine is sprayed from the spray port, and the amount of the liquid medicine is adjusted according to the concentration change of the impurities in the sewage to prevent the liquid medicine from being wasted. After the addition of the medicine is completed, the buffer spring 1 203 can push the piston 201 to reset, block the spray port, and avoid dripping.

[0035] For further reference, Figure 3-Figure 4 , Figure 6-Figure 7 and Figure 9-10 The material receiving assembly includes: a collecting box 301, a material receiving box 302 and a sliding plate 303. Several collecting boxes 301 are respectively fixedly installed on the corresponding end of the connecting rod 18 away from the mounting plate 17. The material receiving box 302 is arranged in a funnel shape. The bottom of the material receiving box 302 is fixedly installed on the top of the collecting box 301. An opening 2 is opened on the top of one side of the collecting box 301. Several sliding plates 303 are respectively arranged in the corresponding opening 2. Both sides of the bottom end of several sliding plates 303 are slidably installed with the collecting box 301 through sliding assemblies.

[0036] When the medicine liquid delivered by the external medicine adding source to the medicine spraying pipe 14 through the medicine adding pipe 13 is sprayed out from the medicine spraying port, the collecting box 301 is driven by the connecting rod 18 to rotate with the mounting plate 17 to the bottom of the medicine spraying port, and the material receiving box 302 can effectively guide the sprayed medicine liquid to flow into the collecting box 301. When the material receiving component rotates to the range approaching, reaching and leaving the highest point and the lowest point, the two sets of opening and closing components are controlled according to their positions, and the sliding plate 303 slides to open the collecting box 301, so that the collecting box 301 can receive and discharge the materials. In the other positions, the sliding plate 303 slides to close the collecting box under the action of the sliding component, completing the circulation process of receiving and discharging the materials, and continuously collecting the medicine liquid sprayed from the medicine spraying port to mix the sewage and the medicine liquid evenly.

[0037] For further reference, Figure 3 and Figure 4 A plurality of stirring rods 15 are fixedly installed at equal distances on both sides of the rotating shaft 11 .

[0038] The stirring rod 15 rotates with the rotating shaft 11 to stir the sewage in the box body 1 horizontally, so as to achieve uniform mixing of the liquid medicine and the sewage, thereby improving the sewage purification effect.

[0039] For further reference, Figure 7-Figure 8 The sliding assembly includes: a slide rail 401, a slider 402 and a buffer spring 403. The two slide rails 401 are respectively fixedly installed on the top inner walls at both ends of the collection box 301. The two sliders 402 are respectively slidably installed on the two slide rails 401. The two sliders 402 are respectively fixedly connected to both sides of one end of the bottom of the sliding plate 303. The buffer spring 403 is horizontally fixedly installed between the slider 402 and the inner wall of the other end of the collection box 301.

[0040] When the material receiving component rotates to the range of approaching, reaching and leaving the highest point and the lowest point, the two groups of opening and closing components are controlled according to their positions, and the sliding plate 303 drives the slider 402 connected to it to slide on the slide rail 401. The buffer spring 2 403 is stretched during the sliding process of the slider 402. As the sliding plate 303 moves, the collecting box 301 gradually opens, and the collecting box 301 is able to receive and discharge materials. In the other positions, the buffer spring 2 403 pulls the slider 402 to slide along the slide rail 401, driving the sliding plate 303 to close the collecting box 301 again, preparing for the material receiving component to reach the material receiving and discharging position next time. The material receiving component and the opening and closing component are coordinated to realize the transportation of the liquid medicine from the top layer to the deep layer of the sewage, so that it can fully react with the sewage and improve the sewage treatment effect.

[0041] For further reference, Figure 3 The transmission assembly includes: an annular support seat 501, a plurality of block ones 502, four annular mounting frames 503 and a plurality of block twos 504. The annular support seat 501 is horizontally fixedly installed on the central inner wall of the bottom of the box body 1. The annular support seat 501 is truncated. A plurality of block ones 502 are fixedly installed on the top of the annular support seat 501 in an annular array. Two annular mounting frames 503 form a group. The two groups of annular mounting frames 503 are respectively arranged on both sides of the rotating shaft 11. One group of annular mounting frames 503 is sleeved on the outside of a plurality of receiving boxes 302 located on the same side. A plurality of block twos 504 are respectively arranged equidistantly and fixedly installed between the two annular mounting frames 503. The block two 504 is meshed with the block one 502.

[0042] The rotating shaft 11 starts to rotate driven by the rotating motor 12. As the rotating shaft 11 rotates, the two groups of annular mounting frames 503 revolve around the rotating shaft 11 along with the material receiving assembly. During the rotation of the annular mounting frame 503, the second block 504 rotates accordingly. When the second block 504 rotates to contact the first block 502, the meshing action of the first block 502 and the second block 504 causes the annular mounting frame 503 to rotate in the vertical direction while revolving. This rotation drives the mounting plate 17 connected thereto to rotate in the vertical direction, thereby causing the position of the connecting rod 18 and the material receiving assembly to change continuously, and cooperate with the collection of the liquid medicine sprayed from the spray port to transport the liquid medicine from the top layer to the deep layer of the sewage, so that it fully reacts with the sewage, thereby improving the sewage treatment effect.

[0043] For further reference, Figure 3-Figure 4 and Figure 9-10 The opening and closing assembly includes: a mounting seat 2 601, two blocking rods 1 602 and a plurality of blocking rods 2 603. The two mounting seats 2 601 are respectively fixedly mounted on the top and bottom of the circumference of the rotating shaft 11. The blocking rod 1 602 is arranged in an arc shape. The two blocking rods 1 602 are respectively rotatably mounted on both sides of one of the mounting seats 2 601 through a torsion spring rotating shaft. The plurality of blocking rods 2 603 are respectively fixedly mounted on the other end of one side of the sliding plate 303 close to the rotating shaft 11.

[0044] When the material receiving assembly rotates with the mounting plate 17, the plurality of baffle rods 603 rotate synchronously therewith. The baffle rod 602 will contact the baffle rod 603 when the material receiving assembly rotates to a specific position. As the material receiving assembly continues to rotate, the baffle rod 602 blocks the baffle rod 603, thereby causing the sliding plate 303 to slide open the collecting box 301, allowing the collecting box 301 to receive or discharge materials. As the material receiving assembly continues to rotate, the baffle rod 603 pushes the baffle rod 602 to rotate around the torsion spring shaft, and the torsion spring is deformed. When the baffle rod 602 rotates to a certain angle, the material receiving assembly continues to rotate away from the specific position, the baffle rod 603 disengages from the baffle rod 602, and the baffle rod 602 rotates back to the initial position under the action of the torsion spring. At the same time, the sliding plate 303 slides in the opposite direction under the action of the sliding assembly to reclose the collecting box 301, thereby automatically controlling the opening and closing of the material receiving assembly according to the position of the material receiving assembly, thereby realizing the transportation of the medicine from the top layer to the deep layer of the sewage.

[0045] For further reference, Figure 3-Figure 4 and Figure 9-10 The angle formed between the collecting box 301 and the connecting rod 18 is between 165 degrees and 175 degrees.

[0046] When the material receiving component just leaves the sewage surface, the opening and closing component opens the collecting box 301, and the residual sewage in the collecting box 301 flows outward through the inclined setting of the collecting box 301 and the material receiving box 302, ensuring that there is no excessive sewage remaining in the collecting box 301 to affect the subsequent material receiving, thereby avoiding overflow due to excessive residual sewage during subsequent material receiving.

[0047] For further reference, Figure 6 A plurality of openings 801 are equidistantly formed on the top of one side of the collecting box 301 close to the sliding plate 303 .

[0048] The mounting plate 17 rotates in the direction away from the opening 801. When the material receiving assembly rotates from the highest point to the lowest point and the collecting box 301 enters the sewage surface, the opening 801 allows the liquid medicine in the collecting box 301 to begin to exchange with the external sewage. As the collecting box 301 rotates, the liquid medicine slowly flows out through the opening 801 and mixes with the sewage. In the interval between reaching and leaving the lowest point, the sliding plate 303 opens to allow the remaining liquid medicine to fully mix with the sewage, thereby improving the mixing effect. When the collecting box 301 is out of the water, the opening 801 is exposed, and the residual sewage in the collecting box 301 flows out through the opening 801, thereby effectively preventing the residual sewage from accumulating excessively in the subsequent material receiving process and affecting the material receiving, thereby ensuring that the entire sewage treatment and dosing operation process is smooth and efficient.

[0049] Working principle: First, the top of the dosing pipe 13 is connected to the external dosing source through the liquid pump, and the sewage to be treated is added to the box body 1 through the feed pipe 9. Then, after the liquid medicine is pumped into the spraying pipe 14 by the external liquid pump, the piston 201 is driven by pressure to move, and the spraying port is opened to spray medicine. Part of the liquid medicine falls on the surface of the sewage, and the rotating motor 12 is started to drive the rotating shaft 11 to rotate. The speed of the rotating shaft 11 is adjusted according to the impurity concentration of the sewage. If the concentration is too high, the speed is increased, and if it is too low, the speed is reduced. When the rotating shaft 11 rotates, the counterweight block 205 of the centrifugal assembly moves due to the centrifugal force, pulling the connecting rod 206 to drive the piston 201, and assisting in adjusting the number of spraying ports through which the liquid medicine can pass. The liquid medicine is sprayed out from the spraying port. During the rotation process, the stirring rod 15 , the connecting rod 18 and the material receiving assembly rotate with the rotating shaft 11 to stir the sewage horizontally. As the rotating shaft 11 rotates, the two sets of annular mounting frames 503 revolve around the rotating shaft 11 with the material receiving assembly. During the rotation of the annular mounting frame 503, the second block 504 rotates accordingly. When the second block 504 rotates to contact the first block 502, the meshing action of the first block 502 and the second block 504 causes the annular mounting frame 503 to rotate in the vertical direction while revolving. This rotation drives the mounting plate 17 connected thereto to rotate in the vertical direction. The mounting plate 17 rotates in the direction away from the opening 801, driving the position of the material receiving assembly to change. The collecting box 301 of the material receiving assembly is driven by the connecting rod 18 to rotate to the position just below the spray port. The material receiving box 302 guides the liquid medicine to flow in, and the opening and closing component controls its opening and closing according to the position of the material receiving component. The collection box 301 is opened to receive or discharge materials when approaching, reaching and leaving the highest point and the lowest point, and the other positions are closed. The sliding component cooperates with the opening and closing component. When opening, the slider 402 stretches the buffer spring 2 403 to make the sliding plate 303 open the collection box 301. When closing, the buffer spring 2 403 pulls the slider 402 to make the sliding plate 303 close the collection box 301. When the material receiving component rotates from the highest point to the lowest point, the collection box 301 enters the sewage surface, and the opening 801 allows the liquid medicine in the collection box 301 to begin to exchange with the external sewage. As the collection box 301 rotates in the water surface, the liquid medicine passes through the opening 801. It flows out slowly and mixes with the sewage. In the interval of reaching and leaving the lowest point, the sliding plate 303 is opened to allow the remaining liquid medicine to be fully mixed with the sewage, thereby improving the mixing effect. When the collecting box 301 is out of the water, the opening 801 is exposed, and the sewage remaining in the collecting box 301 flows out through the opening 801. In addition, when the receiving assembly just leaves the water, the collecting box 301 and the receiving box 302 are inclined to discharge the residual sewage, so that part of the liquid medicine is mixed with the sewage. Finally, the treated water is discharged from the discharge pipe 10, completing the entire sewage treatment and dosing operation process, realizing the transportation of the liquid medicine from the top layer to the deep layer of the sewage, and at the same time, lateral stirring promotes the uniform mixing of the sewage and the liquid medicine, which fully reacts with the sewage, thereby improving the sewage treatment effect.
