Controllable slowly released water purifying medicament dispenser

Abstract

The invention discloses a controllable slowly released water purifying medicament dispenser. The controllable slowly released water purifying medicament dispenser comprises a barrel, a plurality of medicament cores (5) and a driving mechanism for supplying kinetic energy to the barrel, wherein the barrel is of a water permeable structure; the barrel is fixedly connected with a channel bed; the plurality of medicament cores (5) are arranged in the barrel; the driving mechanism is fixedly connected with the barrel. The controllable slowly released water purifying medicament dispenser has the advantages of stable and controllable medicament releasing speed, good acting effect, long acting time, low production cost and the like, and is suitable for various water body conditions; an inner-outer barrel structure with a water permeable grid is adopted, and intermittent communication between an inner barrel and an external water body is realized through relative rotation of the inner barrel and an outer barrel, so that the medicament cores loaded into the barrel are dissolved slowly and released outwards slowly, thereby achieving a long-acting stable purifying effect on pollutants in peripheral water bodies. In the method, the medicament cores are stable in dissolving and releasing speeds, and a remarkable implementation effect is achieved.

Description

technical field [0001] The invention relates to a controllable slow-release water purification drug dispenser, which belongs to the technical field of water environment protection. Background technique [0002] With the rapid development of my country's industrialization and the substantial increase in the degree of agricultural intensification, a large number of pollutants and harmful substances are directly discharged into rivers, lakes and other water bodies, and the resulting water environment pollution has attracted more and more attention. Among them, non-point source pollution has become the most important pollution source affecting the quality of water environment due to its wide scope, difficulty in control, and various types of pollution, such as the discharge of chemical fertilizers and pesticides with rainwater runoff, unreasonable disposal of poultry manure and domestic sewage, Leakage of industrial waste, etc. The impact of these pollutions on the water body i...

Problems solved by technology

However, the cost of some chemical slow-release agents is high, the synthesis conditions are relatively harsh, and it is easy to cause secondary pollution to the environment, such as the application of nanomaterial encapsulation agents

At the same time, after the synthetic drug is placed into the water body, it is greatly affected by factors such as sediment, and the release time of the drug cannot be accurately quantitatively controlled.

Recently, some scholars have begun to focus on the manufacture and improvement of drug release devices, such as installing timing opening and closing devices, and using internal and external pressure compensation devices. These methods are effective, but they are costly, complicated to install, or vulnerable to damage in natural water bodies
