Description

Technical Field

[0001] This utility model relates to the field of water treatment dosing equipment technology, and in particular to an integrated PAM dosing device. Background Technology

[0002] Traditional PAM dosing methods have several drawbacks. Firstly, the hopper structure is simplistic and lacks effective insulation. PAM is highly temperature-sensitive and prone to clumping at low temperatures, affecting normal feeding and transport, leading to inaccurate dosage and consequently impacting treatment effectiveness. Secondly, the mixing device is poorly designed, with simple impeller structures, often single-layer or simple multi-layered, failing to adequately and evenly mix the solution within the tank. This results in uneven mixing, preventing the PAM from fully exerting its effect and reducing treatment efficiency.

[0003] Furthermore, traditional screw propulsion components have a single function, only capable of simple feeding. They cannot effectively break up any clumps of chemicals, easily causing blockages and affecting the normal operation of the dosing device. Moreover, the simple design of the water inlet pipeline prevents sufficient premixing with the chemicals, resulting in uneven mixing and impacting the quality of subsequent chemical solution preparation. Utility Model Content

[0004] To address some of the problems existing in the prior art, this utility model provides an integrated PAM dosing device. By optimizing the design of components such as the hopper structure, stirring assembly, spiral propulsion assembly, and water inlet pipeline, this device can effectively improve the storage, transportation, and mixing of PAM agents, enhance the overall performance of the dosing device, and meet the PAM dosing needs of different industrial and water treatment fields.

[0005] To achieve the above objectives, this utility model provides an integrated PAM dosing device, including a dosing device body, the dosing device body including a housing, a material storage hopper assembly on the housing, a spiral propulsion assembly below the material storage hopper assembly, a cyclone premixer connected to the spiral propulsion assembly, several sets of stirring assemblies inside the housing, a control box on one side of the housing, and a water inlet pipe on the top of the housing.

[0006] As a further improvement of this utility model, in order to reduce the impact of low external temperature on the inner layer of the agent, prevent the PAM agent from clumping, and ensure the normal feeding of the agent, the storage hopper assembly is a double-layer nested structure, including an outer storage hopper and an inner storage hopper. The inner storage hopper is connected to the screw propulsion assembly. A heat insulation layer is formed between the outer storage hopper and the inner storage hopper, and the heat insulation layer is filled with heat insulation material.

[0007] As a further improvement of this utility model, in order to guide the PAM agent to flow towards the spiral propulsion component in a set direction, avoid the agent from accumulating at the bottom of the hopper, and improve the uniformity and stability of the feeding, the bottom of the inner storage hopper is provided with an inclined guide plate, which guides the PAM agent to flow towards the spiral propulsion component.

[0008] As a further improvement of this utility model, in order to ensure effective stirring at various liquid levels and guarantee the stability of the drug solution quality, the stirring assembly includes a stirring drive motor, which is equipped with a stirring shaft and stirring blades. The stirring drive motor is located at the upper part of the housing, and the stirring blades are multi-layer blade structures, including upper blades, middle blades and lower blades. The upper blades and middle blades are inclined blades, and the lower blades are turbine blades.

[0009] As a further improvement of this utility model, in order to conveniently adjust the position of the stirring blade and meet the requirements of stirring effect under different working conditions, an adjustment component is provided between the stirring blade and the stirring shaft. The adjustment component includes a sleeve, the stirring blade is connected to the stirring shaft through the sleeve, the sleeve is fixed to the outer wall of the stirring shaft, and a collar is provided in the sleeve, which is connected to the stirring blade.

[0010] As a further improvement of this utility model, in order to facilitate the output of the treated liquid, the bottom of the tank is provided with an overflow port and a liquid outlet. The liquid outlet is connected to an external dosing pump. The tank is also provided with a water inlet, which extends to the top of the tank through a water inlet pipe. The water inlet is located on one side of the cyclone premixer.

[0011] As a further improvement of this utility model, in order to effectively clean the stubborn agent residue inside the premixer, the water inlet pipe is provided with a water inlet branch pipe, and a high-pressure nozzle is provided inside the cyclone premixer. The high-pressure nozzle is connected to the water inlet branch pipe, and a control valve is also provided on the water inlet branch pipe.

[0012] As a further improvement of this utility model, in order to break up agglomerated agents and restore them to a loose state, the spiral propulsion assembly includes a first feeding spiral and a second feeding spiral arranged vertically. The first feeding spiral includes a first feeding shaft and a crushing shaft arranged on the first feeding shaft. Multiple sets of crushing shafts are arranged and are set at a certain angle to the first feeding shaft. The second feeding spiral includes a second feeding shaft and threaded blades arranged on the second feeding shaft. The first feeding spiral and the second feeding spiral are equipped with a power motor.

[0013] In operation, the operator adds PAM reagent to the hopper assembly. The hopper assembly adopts a double-layer nested structure, with an insulating layer formed between the outer and inner storage hoppers and filled with insulating material. This effectively prevents the reagent from clumping at low temperatures, ensuring the reagent remains in good condition. An inclined guide plate at the bottom of the inner storage hopper guides the reagent flow to the spiral propulsion assembly, preparing it for subsequent conveying.

[0014] The screw propulsion assembly consists of a first feed screw and a second feed screw arranged sequentially from top to bottom. The first feed screw has multiple sets of crushing shafts at a certain angle to the shaft on its first feed shaft. When the reagent enters, the crushing shafts break up any agglomerated reagent, restoring it to a loose state and ensuring smooth reagent delivery. The threaded blades on the second feed screw's second feed shaft stably transport the crushed reagent to the cyclone premixer.

[0015] As the powder enters the tank, the water intake process begins. The water inlet pipe, connected to the inlet, introduces water into the tank. The water enters from the top of the tank and begins to mix with the powder added by the cyclone premixer. At this time, the stirring components start working, with multiple stirring drive motors driving the stirring shaft and stirring blades to rotate. After stirring is completed, the liquid medicine is drawn out by the external dosing pump through the liquid medicine inlet at the bottom of the tank and transported to the designated location. If there is too much liquid medicine in the tank, the overflow port will automatically discharge the excess liquid to maintain stable operation of the device.

[0016] After the drug solution preparation is completed, in order to prevent residual drug powder in the metering feeder from affecting the next use, open the control valve on the water inlet branch pipe, and water is sprayed into the cyclone premixer through the nozzle to thoroughly clean it, ensuring that the inside of the equipment is clean and ready for the next drug solution preparation.

[0017] The beneficial effects of this utility model are as follows:

[0018] Thermal insulation and moisture protection ensure agent quality: The storage hopper assembly adopts a double-layer nested structure, with an insulation layer between the outer and inner layers filled with insulation material. This effectively isolates the agent from the influence of external temperature changes, preventing the agent from deteriorating due to excessively high or low temperatures. Highly efficient crushing and conveying improves dosing efficiency: The crushing shaft of the first feeding screw in the screw propulsion assembly can initially crush the agent, breaking down large particles for easier subsequent mixing with water. The threaded blades of the second feeding screw can stably and continuously convey the agent to the cyclone premixer, ensuring smooth and stable agent delivery and greatly improving dosing efficiency.
