Description

Technical Field

[0001] The utility model belongs to the technical field of sewage dosing facilities, and in particular relates to a pneumatic spray dosing device for adding liquid medicine to sewage. Background Art

[0002] During the chemical production process, the wastewater generated will enter the vortex flotation tank, most of which is a mixture of water and oil, which needs to be purified. Currently, a large amount of oil spill dispersant is added to the wastewater in the tank at one time through the dosing port of the vortex flotation tank. However, since the current dosing method is for workers to carry the medicine barrel and pour it in at one time, the oil spill dispersant will be unevenly added, which is not conducive to the emulsification and dispersion of the floating oil in the tank, and the oil and water cannot be fully contacted and mixed, which cannot achieve the effect of biodegradation and purification of water bodies in the water, and will also cause a waste of medicine. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing adding method may lead to the problem of uneven adding of the oil spill dispersant.

[0004] In order to solve the above technical problems, the specific technical solutions of the utility model are as follows:

[0005] A pneumatic spray dosing device for adding liquid medicine to sewage comprises a medicine storage tank 1, a conical funnel 2, a medicine nozzle 3, a pressure control ball valve 4, a medicine pipeline 5 and a factory air pipeline 6; a conical funnel 2 is arranged on the top of the medicine storage tank 1, and a valve is arranged at the connection between the two; the factory air pipeline 6 is connected with the medicine storage tank 1; one end of the medicine pipeline 5 is connected with the medicine storage tank 1, and the other end is divided into two branch pipelines connected with two drooping medicine nozzles 3, and the pressure control ball valve 4 is arranged on both branch pipelines; the two branch pipelines of the medicine pipeline 5 are respectively suspended above the upstream sewage in two vortex flotation tanks.

[0006] The utility model has the following advantages: it can achieve uniformity in adding the reagent and use efficiency, thereby saving human resources, avoiding a large amount of reagent waste, and improving sewage quality indicators. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0010] like Figure 1 As shown, the pneumatic spray dosing device of the utility model comprises a medicine storage tank 1, a conical funnel 2, a medicine nozzle 3, a pressure control ball valve 4, a medicine pipeline 5, and a factory air pipeline 6; firstly, the medicine storage tank 1 is supported and fixed in a suitable position, the factory air pipeline 6 is connected to the medicine storage tank 1 by welding, and the factory air is switched on and off by a ball valve, an opening is opened above the medicine storage tank 1 and the conical funnel 2 is connected by welding to add oil spill dispersant, and the ball valve is used as a material cut-off valve. After the addition of the oil spill dispersant is completed, the ball valve is closed to ensure that the medicine storage tank remains in a closed state during operation, and the medicine pipeline 5 is inserted into the tank from the opening above the medicine storage tank, leaving enough gap space with the bottom of the tank to ensure that when the factory air pressure delivers the medicine in the medicine storage tank 1, the medicine can meet the normal supply amount. The reagent pipeline 5 is connected to the two pressure control ball valves 4 through a flange, and the speed of reagent addition is adjusted by the opening of the pressure ball valve 4 to avoid waste of reagent use. The reagent pipeline 5 is suspended above the upstream sewage in the vortex concave air flotation tank A / B, and two drooping reagent nozzles 3 are installed below the reagent pipeline 5 in the vortex concave air flotation tank A / B to spray uniform mist reagents, which is beneficial to the emulsification and dispersion of floating oil, so that the oil and water are fully contacted and mixed, so as to achieve the effect of purifying the water body, ensure that the oil content of the sewage is ≤100mg / L, and meet the indicators of qualified sewage delivery.

[0011] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make several modifications and improvements without departing from the principle of the present invention, and these modifications and improvements should also be considered to belong to the protection scope of the present invention.
