Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to a high-efficiency PAM dissolving device. Background Art

[0002] Polyacrylamide (PAM) is a water-soluble polymer widely used in sewage treatment. However, PAM is susceptible to moisture and agglomeration during storage and dosing, which can lead to blockage of pipelines, drug inlets, and drug outlets, reduce dosing efficiency, and increase the difficulty of operation and maintenance. Existing PAM dissolving devices usually use a spiral conveying method, which has problems such as uneven drug distribution and easy blockage.

[0003] For example, CN216878816U discloses an automatically heated PAM dissolving device, comprising a mounting plate, a plurality of supporting legs connected to the lower surface of the mounting plate, a controller fixedly connected to the upper surface of the mounting plate, a heater fixedly connected to the interior of the mounting plate, a storage barrel fixedly connected to the upper surface of the heater, a feed pipe, a discharge pipe, a liquid level sensor and a temperature sensor fixedly connected to the storage barrel, and the feed pipe, the discharge pipe, the liquid level sensor and the temperature sensor all penetrate into the storage barrel, the feed pipe is threadedly connected to a sealing cover, the discharge pipe is connected to a pump and A flow valve is provided, wherein the storage barrel is fixedly connected to a motor, and an output end of the motor is connected to a stirring shaft, and the stirring shaft penetrates into the storage barrel and is fixedly connected to a plurality of stirring rods; by setting a heating and stirring structure, the problem that the PAM raw material cannot be quickly and fully dissolved before use, thus affecting the accuracy and efficiency of subsequent use, can be solved; however, the device puts PAM into the storage barrel through a feeding pipe, and the water vapor in the storage barrel is prone to block the orifice of the feeding pipe, resulting in low dosing efficiency; and the feeding of the feeding pipe is prone to uneven feeding due to the limited size of the orifice, thereby forming block particles in the water, affecting the dissolution effect.

[0004] For example, CN206027471U discloses a PAM dissolving device that can be heated automatically. A tubular heating device is provided on the water inlet pipeline of the PAM automatic dosing and dissolving device. A rotor flowmeter, an electric contact pressure gauge, and a first online temperature monitor are provided on the water inlet pipeline between the water inlet end of the PAM automatic dosing and dissolving device and the water outlet end of the tubular heating device in sequence. The rotor flowmeter is provided close to the water inlet end of the PAM automatic dosing and dissolving device, and a second online temperature monitor is provided on the water inlet pipeline between the water inlet end of the tubular heating device and the electric control valve. However, the tubular heating device can only heat but not keep warm, and the pipeline is not provided with an angle. After the water inlet is stopped, the agent is likely to remain in the pipeline. Under low temperature conditions, once the heating is stopped, condensed water is likely to be generated in the pipeline, and the agent remaining in the pipeline is likely to become hardened, which is likely to cause pipeline blockage. Moreover, since the pipeline is heated, it is difficult to clear the blockage, and the maintenance difficulty is relatively high.

[0005] To this end, we urgently need to provide an efficient PAM dissolution device, optimize the dissolution device to address the problems existing in the use of PAM dissolution in the water treatment process, improve the efficacy of the drug, and avoid the drug clogging the pipes and water pumps, thereby reducing the difficulty of maintenance and increasing the service life of the dissolution device.
