Description

Water treatment device with weighing sensing module and water treatment system

Technical Field

The utility model relates to the field of sewage treatment, in particular to a water treatment device with a weighing sensing module and a water treatment system.

Background

The existing sewage treatment device or system mostly follows the following flow in the aspect of sewage treatment process; introducing the sewage into a container (the container is a tank body or an artificially manufactured barrel), filtering the sewage in the container, feeding the sewage into the container for reaction and other steps for purifying the water, and leading out the treated water and pollutants separated from the sewage from the container.

In order to improve the purification effect of the sewage treatment process, the sewage treatment adopts a sectional sewage treatment process, wherein the sectional sewage treatment process is to introduce sewage into a container, filter the sewage, guide treated water and pollutants out of the container after chemical dosing reaction and other steps, and then introduce next batch of sewage to be treated into the container. Therefore, firstly, the treated water can be prevented from being polluted again due to the mixing with the next batch of sewage, and secondly, the pollutants separated from the previous batch of sewage can not influence the treatment of the next batch of sewage. In order to achieve the steps by adopting an automatic machine, a detection mechanism for detecting the water level and pollutants in the container is required to be arranged, on one hand, the detection mechanism detects the water level data in the container, prevents the sewage from exceeding the treatment capacity and determines the reagent adding amount and the reaction filtering time; on the other hand, the detection mechanism can also detect whether the filtered water or pollutants in the container are completely discharged out of the container, and the auxiliary control mechanism controls the water treatment device.

Referring to the patent disclosed by the applicant, such as patent No. CN214004257U, the applicant adopts a contact type water pressure sensor to detect the low water level pressure in the container during the design process, and then converts the water level data according to the pressure; or the liquid level in the container is detected by adopting a non-contact photoelectric sensor. As shown in fig. 6, the water pressure sensor is disposed in the sewage, but since the device is designed for various severe sewage treatment processes (such as a sewage treatment process in a pig farm), the working environment of the water pressure sensor is severe, which affects the work of the water pressure sensor; and the maintenance of the water pressure sensor when it is disposed in the container is troublesome. However, the photoelectric sensor also has a defect, as shown in fig. 7, firstly, since the pollutants are often attached to various positions of the inner wall of the container, the sensing probe of the photoelectric sensor cannot accurately judge whether the pollutants are completely discharged, so that how long the pollutants are completely discharged can be roughly judged according to experience, and then the discharge time of the pollutants is preset; next, in the subsequent design of the apparatus, the applicant designed a lifting mechanism for lifting and lowering a filtering apparatus (filter element) for filtering sewage in a container to and fro, and a mechanism for stirring the sewage in the container (stirring the sewage accelerates the reaction between the sewage and the water treatment agent). The filter device is lifted from the sewage and falls down, and the sewage in the container generates vortex, which can lead the water level data detected by the photoelectric sensor to change continuously, thus bringing great trouble to the programming work of the subsequent controller.

Therefore, the applicant has conceived a third detection means in the design process for detecting whether the contaminated water and contaminants in the container are discharged or not, and has reprogrammed the controller based on this detection means.
