Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device with a self-cleaning function. Background Technology

[0002] With the acceleration of industrialization and urbanization, the volume of sewage discharge is increasing daily, highlighting the growing importance of sewage treatment. Traditional sewage treatment devices have problems in actual operation. On the one hand, filter components are easily clogged by impurities in the sewage, leading to a decrease in filtration efficiency. Frequent manual cleaning not only increases maintenance costs but also affects the uptime of the sewage treatment device. On the other hand, the addition of chemicals using traditional methods is often difficult to control precisely, resulting in unstable sewage treatment effects that cannot meet increasingly stringent environmental standards. Therefore, there is an urgent need to develop a device with self-cleaning capabilities that can efficiently and accurately treat sewage. Utility Model Content

[0003] To address some of the problems existing in the prior art, this utility model provides a wastewater treatment device with a self-cleaning function. This device integrates stirring, filtration, drug administration, and self-cleaning functions into one unit, achieving efficient and automated wastewater treatment and possessing broad market application prospects.

[0004] To achieve the above objectives, this utility model provides a wastewater treatment device with a self-cleaning function, including a tank with a first cover and a second cover. An inlet pipe and an outlet pipe are respectively installed at both ends of the tank. Multiple partitions are installed inside the tank, dividing it into a stirring zone, a preliminary filtration zone, a secondary filtration zone, and a water storage zone. The stirring zone includes a stirring assembly for stirring the wastewater. A filter basket is installed in the preliminary filtration zone for initially filtering large particulate impurities. A filter screen assembly is installed in the secondary filtration zone, and a suction cleaning assembly is fitted to the outside of the filter screen assembly. The secondary filtration zone also includes a drug delivery assembly for adding treatment agents to the wastewater.

[0005] In operation, wastewater flows into the mixing zone of the tank through the inlet pipe. The mixing drive motor starts and drives the mixing blades through the transmission shaft to rotate and mix the wastewater, so that impurities are evenly dispersed. Then the wastewater enters the preliminary filtration zone, where the filter basket performs preliminary filtration, intercepting large particles of impurities. The filter basket can be disassembled and cleaned separately through the nut fastening components at both ends. Next, the wastewater that has passed the preliminary filtration enters the secondary filtration zone. At this time, the dosing metering pump draws the medicine from the medicine storage tank according to the preset amount and adds it to the wastewater through the delivery pipe. At the same time, the drive motor on the second cover plate drives the filter cylinder in the filter cylinder assembly to rotate through the transmission belt and collar, further filtering the fine impurities in the wastewater. During the filtration process of the filter cylinder, the suction pump starts and sucks the dirt accumulated on the outside of the filter cylinder into the drain pipe through the suction head and discharges it. Finally, the treated water flows into the storage area and is discharged through the outlet pipe.

[0006] The beneficial effects of this utility model are as follows: By rationally setting up a stirring zone, a preliminary filtration zone, a secondary filtration zone, and a water storage zone, this utility model achieves zoned sewage treatment, effectively improving treatment efficiency. The stirring component ensures that the sewage is fully stirred before entering the filtration zone, which is beneficial for subsequent filtration and reagent mixing; the filter basket and filter screen assembly form a two-stage filtration system, effectively intercepting impurities of different particle sizes, and the filter basket can be disassembled and cleaned separately for convenient maintenance; the rotating design of the filter screen assembly and its cooperation with the suction cleaning component achieve a self-cleaning function, reducing the frequency of manual cleaning and ensuring stable filtration results; at the same time, the dosing component precisely controls the addition of reagents, improving the sewage treatment effect.

[0007] As a further improvement of this utility model, in order to realize the rotation of the filter cylinder and enhance the filtration effect, while facilitating the cleaning of impurities, reducing filter clogging, and extending service life, the filter cylinder assembly includes a filter cylinder with support frames movably fitted at both ends; a second cover plate is disposed above the filter cylinder, and a drive motor and a through hole are provided on the second cover plate; a collar is installed on the filter cylinder, and a transmission belt is provided between the collar and the output end of the drive motor; the transmission belt passes through the through hole, and the drive motor drives the filter cylinder to rotate through the transmission belt and the collar.

[0008] As a further improvement of this utility model, in order to remove impurities from the filter screen and equipment in a timely and comprehensive manner and ensure the continuous and stable operation of the device, the sludge suction cleaning component includes multiple brackets, which are fixedly connected to the housing; an mounting plate is provided on the bracket, and several suction heads are evenly arranged on the mounting plate; a drain pipe is connected to the rear end of the suction head, and a sludge suction pump is provided at the end of the drain pipe; the sludge suction pump is activated and the sludge is sucked into the drain pipe through the suction head for discharge.

[0009] As a further improvement of this utility model, in order to achieve precise addition of the agent, improve the scientificity and effectiveness of sewage treatment, and enhance the sewage treatment effect, the drug delivery component includes a drug storage tank, a drug metering pump, and a delivery pipe. The drug metering pump and the delivery pipe are both installed on the drug storage tank. The drug storage tank is used to store the treatment agent, and the drug metering pump extracts the agent from the drug storage tank according to the preset agent quantity and delivers the agent to the sewage in the secondary filtration zone through the delivery pipe.

[0010] As a further improvement of this utility model, in order to facilitate the individual disassembly, replacement and cleaning of the filter basket, reduce maintenance costs and improve the maintainability of the equipment, the filter basket is provided with nut fastening components at both ends and is connected and fixed to the housing through the nut fastening components, so that the filter basket can be individually disassembled, replaced and cleaned.

[0011] As a further improvement of this utility model, in order to achieve thorough mixing of wastewater and improve the effect of subsequent treatment processes, the stirring assembly includes a stirring drive motor, the output end of which is equipped with a transmission shaft; a stirring blade is fitted on the transmission shaft, and the stirring drive motor can drive the stirring blade to rotate through the transmission shaft when started.
