Problems solved by technology

These structures will occupy a large part of the volume of the vehicle, which does not meet the requirements of the vehicle size
[0011] 2. The metering of each drug addition is fixed, and the drug cannot be added according to the actual flow of sewage
These structures will also occupy a large part of the volume of the vehicle, which does not meet the size requirements of the vehicle
[0020] 2. The metering of each drug addition is still fixed, and it is still impossible to add drugs according to the actual flow of sewage
There is still the problem of insufficient or excessive addition of drugs

Embodiment Construction

[0034] The present application will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0035] Such as figure 1 As shown, a dosing device for mobile sewage treatment equipment includes a raw water inlet pipe 1, a raw water outlet pipe 2, and a drug reaction tank 3 suspended between the raw water inlet pipe 1 and the raw water outlet pipe 2.

[0036] The volume of the drug reaction tank 3 is twice the maximum flow per minute in the raw water inlet pipe 1 . In this way, the volume of the drug reaction pool 3 can be designed to be very small, and it can be set in the air without occupying the actual contact space of the vehicle tool, thus saving the space of the vehicle tool.

[0037] The drug reaction pool 3 is preferably in the shape of an ellipse cylinder, and the bottom of the drug reaction pool 3 is provided with a gas pipeline 4 , which passes through the bottom of the drug reaction pool 3 and is connecte...

Abstract

The invention discloses a chemical dosing device being capable of automatically computing the chemical dosing dose and frequency and used for sewage treatment equipment. The chemical dosing device comprises a raw water inlet pipe, a raw water outlet pipe and a chemical reaction tank hung in the air, wherein a gas pipeline is arranged at the bottom of the chemical reaction tank, passes through the bottom of the chemical reaction tank and is connected with a ball; a plurality of vent holes are uniformly formed in the ball; at least one powdery chemical box is arranged at the top of the chemical reaction tank; a chemical delivery pipe is arranged at the bottom of each powdery chemical box; the other end of the chemical delivery pipe is connected with a sprinkler head; a flow sensor and a flow rate sensor, which are connected with a PLC (programmable logic controller), are arranged on the raw water inlet pipe. After adopting the structure, the chemical dosing device has the beneficial effects that the chemical reaction tank has small volume and is hung in the air and does not occupy the actual contact space of vehicle-mounted tools, thus saving the space of the vehicle-mounted tools; besides, the chemical dosing device can automatically compute the chemical dosing dose and frequency according to the flow value and flow rate value data of raw water in the water inlet pipe, so that the chemical dosing dose is accurate.

Description

technical field [0001] The application relates to a dosing device, in particular to a dosing device for mobile sewage treatment equipment. Background technique [0002] At present, the discharge of urban domestic sewage is the main pollution source of urban water in China, and the treatment of urban domestic sewage is the top priority of urban water conservation and urban water environment protection at present and in the future. This requires us to take the construction of domestic sewage treatment facilities as a priority The important content of urban infrastructure is to be grasped, and it is a matter of urgency. [0003] Sewage treatment is an important process to deal with water pollution. Use physical, biological, and chemical methods to treat industrial wastewater and domestic sewage to separate solid pollutants in water and reduce organic pollutants and eutrophic substances (mainly nitrogen and phosphorus compounds) in water, thereby reducing the impact of sewage o...
