Description

Technical Field

[0001] This utility model relates to the field of dosing device technology, and in particular to a vortex anti-clogging dosing device. Background Technology

[0002] Chemical dosing devices are key equipment used in industrial production, water treatment and other fields to accurately inject chemical agents such as flocculants, corrosion inhibitors, and bactericides into the fluids to be treated (water, industrial media, etc.). Their core function is to achieve water purification, equipment corrosion prevention, and scale prevention by fully mixing the agents with the fluid. They are widely used in municipal sewage treatment, power plant circulating water systems, chemical production and other scenarios.

[0003] In existing technologies, traditional dosing devices mostly adopt a single stirring structure or directly deliver the agent through pipelines, which generally have two major problems: First, the agent is prone to precipitation and agglomeration during storage in the tank, resulting in uneven mixing of the agent and affecting the treatment effect; second, the discharge pipeline is prone to blockage due to the accumulation of sediment particles, requiring frequent shutdowns for cleaning, reducing equipment operating efficiency, and making it difficult to achieve integrated and efficient operation of stirring to prevent sedimentation and discharge to prevent blockage. This cannot meet the stringent requirements of industrial scenarios for the stability, anti-blockage, and convenience of dosing devices. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a vortex anti-clogging dosing device, which solves the problems of easy precipitation and clumping of drugs in existing dosing devices, easy blockage of the discharge pipeline, and difficulty in achieving efficient integrated operation of stirring to prevent precipitation and discharge to prevent blockage.

[0005] This utility model also provides a swirling anti-clogging dosing device, including a tank, a discharge pipe connected to the bottom of the tank, and a switch valve disposed on the discharge pipe. The tank is internally equipped with a swirling anti-clogging component, which includes: a piston plate one and a piston plate two, both of which are slidably sealed to the inner wall of the tank; multiple water-passing inclined pipes, circumferentially equidistantly arranged on the piston plate one, with each water-passing inclined pipe forming a 15° angle with the surface of the piston plate one; a first driving mechanism for independently raising and lowering the piston plate one; and a second driving mechanism for independently raising and lowering the piston plate two. The raising and lowering motion of the piston plate one causes the liquid medicine in the tank to form a swirling flow through the water-passing inclined pipes; the lowering motion of the piston plate two causes the liquid medicine to flow at high speed through the water-passing inclined pipes under pressure, forming a strong swirling flow.

[0006] According to the swirl anti-clogging dosing device of this utility model, the first driving mechanism includes a motor and a lead screw. The motor is fixedly mounted on a bracket above the tank. The lead screw is connected to the output end of the motor and threadedly engaged with a piston plate.

[0007] According to the swirl anti-clogging dosing device of this utility model, the second driving mechanism includes a second motor and a second lead screw. The second motor is fixedly mounted on the bracket, and the second lead screw is connected to the output end of the second motor and threadedly engaged with the second piston plate.

[0008] The swirl anti-clogging dosing device according to this utility model also includes multiple limiting rods, the limiting rods are fixed below the bracket, and the piston plate one and piston plate two are slidably sleeved on the limiting rods.

[0009] According to the swirl anti-clogging dosing device of this utility model, both piston plate one and piston plate two are provided with elastic sealing rings on their outer periphery, and the elastic sealing rings are tightly abutted against the inner wall of the tank.

[0010] According to the swirl anti-clogging dosing device of this utility model, the upper surface of the support is provided with multiple lifting rings.

[0011] According to the swirl anti-clogging dosing device of this utility model, the lower end of the limiting rod is fixedly connected to an anti-detachment block, and the diameter of the anti-detachment block is larger than the diameter of the limiting rod.

[0012] Beneficial effects: In the swirling anti-clogging dosing device of this technical solution, when the piston plate moves up and down along the limiting rod, the liquid medicine is forced to pass through the water-passing inclined pipes that are 15° angled and circumferentially distributed during the movement of the piston plate, forming a swirling flow, thereby agitating the liquid medicine in the tank and preventing the medicine from settling and clumping. When discharging the liquid medicine, after piston plate one is lowered to the bottom of the tank, piston plate two is pressed down. Under the action of pressure, the liquid medicine passes through the water-passing inclined pipe of piston plate one at high speed, forming a swirling flow again.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-3 This utility model embodiment provides a swirl anti-clogging dosing device, which includes: a tank 5, a dosing pipe 6 connected to the bottom of the tank 5, and a switch valve 7 disposed on the dosing pipe 6; Considering that traditional equipment is prone to reagent precipitation and clumping, and easy blockage during discharge, making it impossible to achieve integrated anti-precipitation and anti-clogging measures, a vortex anti-clogging component is installed inside the tank 5. The vortex anti-clogging component includes: piston plate 10 and piston plate 8, both of which are slidably sealed to the inner wall of the tank 5; multiple water-passing inclined pipes 13 are circumferentially and equidistantly arranged on piston plate 10, and each water-passing inclined pipe 13 forms a 15° angle with the surface of piston plate 10. When piston plate 10 rises and falls, the liquid medicine generates a vortex through the water-passing inclined pipes 13 at the 15° angle. When piston plate 8 is pressed down, it pushes the liquid medicine at high speed through the water-passing inclined pipes 13 to form a strong vortex. The vortex and strong vortex can disperse reagent precipitation and prevent clumping, while the high-speed fluid avoids blockage of the discharge pipeline, thus achieving integrated anti-precipitation and anti-clogging measures. The first drive mechanism is used to drive the piston plate 10 to rise and fall independently; the second drive mechanism is used to drive the piston plate 28 to rise and fall independently; wherein, the rising and falling movement of the piston plate 10 causes the liquid medicine in the tank 5 to form a swirling flow through the water-passing inclined pipe 13; the downward pressing movement of the piston plate 28 causes the liquid medicine to flow at high speed through the water-passing inclined pipe 13 under pressure to form a strong swirling flow.

[0017] In summary, the improvement of this embodiment lies in: When the piston plate 10 moves up and down along the limiting rod 11, the liquid medicine is forced to pass through the water-passing inclined pipes 13, which are equidistant from each other at a 15° angle, during the process of the piston plate 10 moving up and down, forming a swirling flow, thereby stirring the liquid medicine in the tank 5 and preventing the medicine from settling and clumping. When discharging the liquid medicine, after piston plate 10 is lowered to the bottom of tank 5, piston plate 28 is pressed down. Under the action of pressure, the liquid medicine passes through the water-passing inclined pipe 13 of piston plate 10 at high speed, forming a swirling flow again. During the discharge process, it flushes the discharge pipe 6, reducing the risk of blockage in the discharge pipe 6.

[0018] Based on the above, other structures also need to be disclosed in detail, such as: Considering the lack of an independent mechanism to drive the piston plate 10, making it impossible to control its lifting and lowering to form a vortex as needed, the first driving mechanism includes a motor 2 and a lead screw 9. The motor 2 is fixedly mounted on the bracket 4 above the tank 5. The lead screw 9 is connected to the output end of the motor 2 and threadedly engaged with the piston plate 10. After the motor 2 starts, it drives the lead screw 9 to rotate. The lead screw 9 threadedly engages with the piston plate 10, converting the rotational motion of the motor into the linear lifting and lowering motion of the piston plate 10. This allows for precise control of the lifting and lowering speed and stroke of the piston plate 10, ensuring that the liquid medicine forms a stable vortex and meeting the anti-sedimentation requirements under different working conditions.

[0019] Considering the lack of an independent mechanism to drive the piston plate 2, making it difficult to push the liquid medicine to form a strong swirling flow to prevent clogging, the second driving mechanism includes a motor 2 3 and a lead screw 2 12. The motor 2 3 is fixedly mounted on the bracket 4, and the lead screw 2 12 is connected to the output end of the motor 2 3 and threadedly engaged with the piston plate 2 8. When the motor 2 3 starts, it drives the lead screw 2 12 to rotate. The lead screw 2 12, threadedly engaged with the piston plate 2 8, drives the piston plate 2 8 to move downward at a uniform speed. The downward pressure of the piston plate 2 8 generates pressure, forcing the liquid medicine to flow at high speed through the water inclined pipe 13 to form a strong swirling flow, enhancing the flushing force on the pipeline and effectively preventing clogging.

[0020] Considering that piston plate one and piston plate two need to remain stable when rising and falling, multiple limiting rods 11 are also included. The limiting rods 11 are fixed below the bracket 4. Piston plate one 10 and piston plate two 8 are slidably sleeved on the limiting rods 11. The limiting rods 11 are fixed below the bracket 4, and piston plate one 10 and piston plate two 8 slide along the limiting rods 11. This limits the lateral displacement of the piston plates, ensuring that they always move along the axis of the tank body 5, ensuring stable generation of vortex, and maintaining the sealing fit between the piston plates and the tank body.

[0021] Both piston plate 10 and piston plate 8 are provided with elastic sealing rings on their outer periphery, and the elastic sealing rings are tightly abutted against the inner wall of the tank body 5.

[0022] Multiple lifting rings 1 are provided on the upper surface of the bracket 4.

[0023] An anti-detachment block is fixedly connected to the lower end of the limiting rod 11, and the diameter of the anti-detachment block is larger than the diameter of the limiting rod 11.

[0024] Working principle: Raising piston plate 28 to its highest position opens tank 5 to store the medicine. The medicine is stored in tank 5. During the stirring stage, motor 2 drives screw 9 to drive piston plate 10 to rise and fall steadily along limit rod 11 (the rising and falling is adjusted by the forward and reverse rotation of motor 2). Under the squeezing action of piston plate 10, the liquid medicine in tank 5 is forced through the circumferentially distributed inclined pipes 13 at a 15° angle, forming a high-speed swirling flow. The centrifugal force and turbulence effect generated by the swirling flow are used to achieve uniform stirring of the liquid medicine and prevent the medicine from settling and clumping. During the discharge stage, the piston plate 10 is lowered to the bottom of the tank 5 by motor 2. Then, the switch valve 7 is opened and motor 3 drives the lead screw 12 to drive the piston plate 8 to press down at a constant speed along the limit rod 11. Under the pressure of the piston plate 8, the liquid flows at high speed through the water-passing inclined pipe 13 of the piston plate 10, forming a strong swirling flow again. The swirling flow can not only ensure that the concentration of the discharged liquid is uniform, but also flush the inner wall of the discharge pipe 6 to prevent the accumulation of sediment particles and blockage of the pipeline. Throughout the process, the limit rod 11 always limits the movement trajectory of piston plate 10 and piston plate 8, ensuring that the two operate independently and accurately. The bracket 4 provides stable support for components such as motor 2 and motor 3, ultimately realizing the integrated operation of drug stirring to prevent sedimentation and pressurized swirling to prevent blockage and discharge.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
