Water treatment reagent dispensing device

Abstract

This utility model discloses a water treatment reagent dispersion device, including a treatment tank, a delivery pipe, and a stirring assembly. The delivery pipe is installed inside the treatment tank, and an air pump is fixedly connected to the left end of the treatment tank. The delivery pipe is fixedly connected to the air pump, and the stirring assembly is installed at the top of the treatment tank. This utility model uses the air pump to deliver gas through the delivery pipe to a distribution pipe, which then delivers the gas to an aeration disc through an outlet pipe. As needed, a first motor is activated to rotate a baffle, adjusting the overlap between the second and first air holes to control the amount and speed of bubble discharge. The bubbles enter the treatment tank through the first air hole, causing water flow, promoting reagent dispersion, improving mixing efficiency, and avoiding damage to the generated flocs. This solves the problem that the rotation of the stirring rod generates shear force, which breaks up the already formed flocs, causing them to redisperse into smaller particles, thus affecting the water treatment effect.

Description

Technical Field

[0001] This utility model belongs to the field of reagent dispersion devices, specifically relating to a water treatment reagent dispersion device. Background Technology

[0002] Water treatment processes are widely used in industrial, agricultural, and municipal sectors to purify water sources, remove pollutants, and improve water quality. With increasingly stringent water quality requirements, water treatment technologies are gradually developing towards higher efficiency, energy conservation, and environmental friendliness. Flocculation, coagulation, and sedimentation processes in water treatment are key steps in removing suspended solids, dissolved organic matter, and heavy metal ions from water, typically relying on the addition and dispersion of different types of water treatment reagents (such as flocculants and coagulants).

[0003] Existing reagent dispersion devices typically employ a motor-driven stirring rod to mix reagents with water through mechanical motion, thereby improving mixing efficiency and reagent dispersion. The motor-driven stirring rod or paddle rotates rapidly, generating strong shear forces and turbulent flow fields, which in turn rapidly disperses water treatment reagents into the water body. This effectively reduces sedimentation or aggregation of reagents in the water, ensuring that reagents can be quickly and evenly distributed to all areas of the water body, thus enhancing the contact efficiency and reaction rate between reagents and pollutants in the water.

[0004] Because the rotation of the stirring rod generates shear force, as the stirring rod rotates, the shear force not only helps to disperse the reagent, but may also have a negative impact on the flocs generated in the water, causing the already formed flocs to be broken up and redispersed into smaller particles, thus affecting the water treatment effect.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5 This utility model provides an embodiment of a water treatment reagent dispersion device, including a treatment tank 1; it also includes a conveying pipe 101 and a stirring assembly; the conveying pipe 101 is arranged inside the treatment tank 1, and an air pump 102 is fixedly connected to the left end of the treatment tank 1. The conveying pipe 101 is fixedly connected to the air pump 102. Multiple diversion pipes 103 are fixedly connected to the outer wall of the conveying pipe 101. An aeration disc 104 is arranged at the upper end of the diversion pipe 103. A first air hole 105 is opened through the upper end of the aeration disc 104. A baffle 106 is rotatably arranged on the inner wall of the aeration disc 104. A second air hole 107 is opened through the upper end of the baffle 106. A first motor 108 is arranged inside the aeration disc 104. The baffle 106 is fixedly connected to the output end of the first motor 108. 1. An agitator is installed at the top. By starting the air pump 102, gas is delivered to the diversion pipe 103 through the delivery pipe 101. The diversion pipe 103 then delivers the gas to the aeration plate 104 through the air outlet pipe 4. As needed, the first motor 108 is started to drive the baffle 106 to rotate, adjusting the overlap between the second air hole 107 and the first air hole 105, controlling the amount and speed of bubble discharge. The bubbles enter the treatment tank 1 through the first air hole 105, driving the water to flow, promoting the accelerated dispersion of reagents and improving mixing efficiency. This avoids damaging the generated flocs and solves the problem that the shear force generated by the rotation of the agitator rod causes the already formed flocs to be broken up and redispersed into smaller particles, thus affecting the water treatment effect.

[0022] Please see Figures 1-4In this embodiment, a first fixing rod 2 is fixedly connected to the inner wall of the aeration disc 104, and a protective shell 3 is fixedly connected to the other end of the first fixing rod 2. A first motor 108 is fixedly connected to the top of the inner wall of the protective shell 3. The diameters of the first air hole 105 and the second air hole 107 are equal. Multiple air outlet pipes 4 are fixedly connected to the outer wall of the diversion pipe 103. The multiple air outlet pipes 4 are equidistantly distributed. A threaded sleeve 5 is fixedly connected to the lower end of the aeration disc 104. The threaded sleeve 5 is threadedly connected to the air outlet pipes 4. A stirring tank 6 is provided at the upper end of the treatment box 1. A second fixing rod 7 is fixedly connected to the wall, and the other end of the second fixing rod 7 is fixedly connected to the inner wall of the treatment tank 1. A sealing cover 8 is rotatably installed on the upper end of the mixing tank 6. The first fixing rod 2 fixes the position of the protective shell 3. The protective shell 3 protects the first motor 108, preventing water and reagents from corroding the motor and extending the service life of the motor. The diameters of the first air hole 105 and the second air hole 107 are equal. When the two coincide, they can discharge air bubbles to the maximum extent. When they are misaligned, the exhaust volume can be precisely adjusted to ensure the accuracy of aeration adjustment.

[0023] Please see Figure 5 In this embodiment, the stirring assembly includes a rotating rod 201. The rotating rod 201 is rotatably mounted on the bottom of the inner wall of the stirring tank 6. A second motor 202 is fixedly connected to the lower end of the stirring tank 6. The rotating rod 201 is fixedly connected to the output end of the second motor 202. The second motor 202 is used to drive the rotating rod 201 to rotate. A plurality of stirring plates 203 are fixedly mounted on the outer wall of the rotating rod 201. The stirring plates 203 are inclined. A connecting rod 204 is fixedly mounted on the outer wall of the rotating rod 201. An mounting plate 205 is fixedly mounted on the outer side of the connecting rod 204. A scraper 206 is slidably mounted on the inner wall of the mounting plate 205. The outer wall surface of the scraper 206 is in contact with the inner wall surface of the stirring tank 6. The mixing tank 6 is equipped with a discharge pipe 207 fixed to the lower edge. A solenoid valve 208 is fixed to one end of the discharge pipe 207 near the mixing tank 6. By starting the second motor 202, the rotating rod 201 is driven to rotate. The stirring plate 203 on the rotating rod 201 stirs the reagent, making the reagent dissolve or dilute evenly. During the rotation, the scraper 206 rotates with the rotating rod 201 to scrape off the reagent residue on the inner wall of the mixing tank 6. The solenoid valve 208 controls the opening and closing of the discharge pipe 207, which can precisely control the amount and timing of the stirred reagent entering the treatment box 1. Combined with the aeration and stirring in the treatment box 1, the reagent is accurately dispersed.

[0024] When using it, first open the sealing cover 8 of the mixing tank 6, put the water treatment reagent into the mixing tank 6, add an appropriate amount of water, start the second motor 202 to drive the rotating rod 201 to rotate, and the stirring plate 203 on the rotating rod 201 will stir the reagent to make the reagent dissolve or dilute evenly. During the rotation, the scraper 206 rotates with the rotating rod 201 to scrape off the reagent residue on the inner wall of the mixing tank 6.

[0025] After stirring is completed, the solenoid valve 208 on the discharge pipe 207 is opened, and the reagent in the stirring tank 6 enters the treatment tank 1 through the discharge pipe 207 to mix with the sewage. The gas is transported to the diversion pipe 103 through the conveying pipe 101 by the air pump 102. The diversion pipe 103 then transports the gas to the aeration plate 104 through the air outlet pipe 4. As needed, the baffle 106 is rotated by starting the first motor 108 to adjust the overlap between the second air hole 107 and the first air hole 105, and to control the amount and speed of bubble discharge. The bubbles enter the treatment tank 1 through the first air hole 105, which drives the water to flow, promotes the accelerated dispersion of the reagent and improves the mixing efficiency.

[0026] Through the above steps, the gas is transported to the diversion pipe 103 through the delivery pipe 101 by the air pump 102, and then the gas is transported to the aeration plate 104 through the air outlet pipe 4. As needed, the baffle 106 is rotated by starting the first motor 108, and the overlap between the second air hole 107 and the first air hole 105 is adjusted to control the amount and speed of bubble discharge. The bubbles enter the treatment tank 1 through the first air hole 105, driving the water to flow, promoting the accelerated dispersion of reagents and improving the mixing efficiency. This avoids damaging the generated flocs and solves the problem that the shearing force generated by the rotation of the stirring rod causes the already formed flocs to be broken up and redispersed into smaller particles, thus affecting the water treatment effect.
