Embodiment 1

[0010] Example 1: Continuously Quantitative Liquid Molluscicide Suspension Dosing Device

[0011] The drug storage room is 12×17×28cm, the glass rotameter is 1.6-16.0L / h, the convection suspension room is 12×17×28cm, the liquid molluscicide is poured into the drug storage room, which can make the liquid molluscicide in the drug storage room The flow rate of the liquid molluscicide can be controlled by the glass rotameter to 1.6-16.0L / h. The continuous quantitative drug enters the suspension chamber, and the convective vortex is formed through the water inlet and the suspension liquid outlet to form a uniform suspension liquid. The uniform suspension medicinal liquid is sprayed by a molluscicide machine to kill molluscs, so that the dosage can be uniform and stable, the efficacy of the medicine can be fully exerted, the quality of molluscicide can be improved, the use is convenient, and the efficacy can be improved.

Embodiment 2

[0012] Example 2: Continuously Quantitative Liquid Molluscicide Suspension Dosing Device

[0013] The drug storage room is 12×17×28cm, the glass rotameter is 1.6-16.0L / h, the convection suspension room is 20×30×38cm, and the liquid molluscicide is poured into the drug storage room, which can make the liquid molluscicide in the drug storage room The flow rate of the liquid molluscicide can be controlled by the glass rotameter to 1.6-16.0L / h. The continuous quantitative drug enters the suspension chamber, and the convective vortex is formed through the water inlet and the suspension liquid outlet to form a uniform suspension liquid. The uniform suspension medicinal liquid is sprayed by a molluscicide machine to kill molluscs, so that the dosage can be uniform and stable, the efficacy of the medicine can be fully exerted, the quality of molluscicide can be improved, the use is convenient, and the efficacy can be improved.

Embodiment 3

[0014] Example 3: Continuously Quantitative Liquid Molluscicide Suspension Dosing Device

[0015] The drug storage room is 20×30×38cm, the glass rotameter is 1.6-16.0L / h, the convection suspension room is 20×30×38cm, and the liquid molluscicide is poured into the drug storage room, which can make the liquid molluscicide in the drug storage room The flow rate of the liquid molluscicide can be controlled by the glass rotameter to 1.6-16.0L / h. The continuous quantitative drug enters the suspension chamber, and the convective vortex is formed through the water inlet and the suspension liquid outlet to form a uniform suspension liquid. The uniform suspension medicinal liquid is sprayed by a molluscicide machine to kill molluscs, so that the dosage can be uniform and stable, the efficacy of the medicine can be fully exerted, the quality of molluscicide can be improved, the use is convenient, and the efficacy can be improved.

Abstract

The invention discloses a continuous quantitative suspension dosing device of liquid molluscicide, which belongs to the technical field of snail control of prevention and cure of schistosomiasis. The suspension dosing device comprises a glass rotameter (1), a flow regulating valve (2), a suspension pressure-regulating valve (3), a convection suspension chamber (4), a medicine storage chamber (5), a flowmeter medicine inlet (6), a liquid medicine suspension chamber conduit (7), a water inlet (8) and a suspension liquid medicine outlet (9). The flow of the liquid molluscicide of the medicine storage chamber can be controlled at 1.6-25.0L / h by the glass rotameter; the continuous quantitative molluscicide enters the convection suspension chamber and is formed into a convection vortex at the suspension liquid medicine outlet through the water inlet, and thereby, the even suspension liquid medicine can be formed; the even suspension liquid medicine is sprayed by a snail killing machine to kill snails, thereby achieving the advantages that the dose is even and stable, the pesticide effect is sufficiently produced, the snail killing quality is improved, the use is convenient, the labor and time are saved, the high efficiency is improved and the like, which lays the foundation for further controlling schistosomiasis.

Description

technical field [0001] A continuous and quantitative liquid molluscicide suspension dosing device belongs to the technical field of molluscicide prevention and control of schistosomiasis. Background technique [0002] Niclosamide (Niclosamide) is the only molluscicide recommended by WHO since 1972. This drug is insoluble in water. Usually, Niclosamide is made into 50% Niclosamide ethanolamine salt wettable powder, and Xiangjiang- 18 or 25 spray mollusc exterminator, or 5L hand mollusc exterminator to kill oncomelania. Due to the unsatisfactory dissolubility and dispersibility of various powders of niclosamide, small lumps of precipitates can easily block the spraying equipment, resulting in difficulty in use and uneven concentration of the liquid medicine; Unevenness, these all make molluscicide effect decline. At present, niclosamide has been made into a liquid medicine-suspension agent for on-site application, which provides the possibility for the development of continu...
