Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device that facilitates filter replacement. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of ordinary people's daily lives.

[0003] Wastewater treatment consists of three main parts: physical treatment, chemical treatment, and biological treatment. Biological treatment is microbial treatment, which involves introducing aerobic bacteria to degrade organic matter in wastewater. During the degradation process, continuous aeration of the wastewater is required. Additionally, targeted chemicals are added to the wastewater. Commonly used chemicals include flocculants, coagulants, conditioners, and demulsifiers. The chemicals are formulated according to the size of the water body and then added to the wastewater. The chemicals react with some of the pollutants in the water, and in conjunction with other processes, the wastewater can be purified over a period of time.

[0004] Existing wastewater treatment devices fail to mix the wastewater thoroughly after the chemicals are added, hindering the effective treatment of the wastewater. Furthermore, sludge and impurities tend to adhere to the bottom of the wastewater treatment tank after treatment, making cleaning difficult. Additionally, the fixed installation of the filter mechanism at one end of the wastewater treatment tank makes disassembly and cleaning inconvenient, potentially causing blockages and affecting drainage.

[0005] Therefore, we designed a wastewater treatment device that facilitates filter replacement to meet the needs of practical applications. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a wastewater treatment device that facilitates filter replacement.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The moving mechanism includes a moving plate, with guide rods sliding through both ends of the moving plate and a rotating rod rotating through the middle. A scraping frame is fixed at the top of the moving plate, and a stirring blade is rotatably installed inside the scraping frame.

[0010] The filtration mechanism includes a filter screen, an installation frame is fixed to the outside of the filter screen, the installation frame is detachably installed inside one end of the sewage treatment tank, a receiving plate is fixed to the bottom end of the installation frame, and a fastening mechanism is provided at the top end of the installation frame.

[0011] In detail, the rotating rod rotates through the middle of the top of the inside of the sewage treatment tank, and a motor is installed at one end of the rod. The motor is fixedly installed at the top of the outside of the sewage treatment tank.

The scraping frame has a U-shaped structure, and support rods are evenly fixed at the bottom of its interior and at the bottom of the moving plate. The support rods are vertically set, and rotating sleeves are slidably sleeved on their surfaces. The stirring blades are evenly fixed on the surface of the rotating sleeves and are distributed in a cross shape.

[0014] In detail, the sewage treatment tank has an installation groove at one end, a recess at the bottom of the installation groove, and snap-fit ​​grooves on both sides of the installation groove. The installation frame is vertically slidably installed inside the installation groove. The receiving plate is rectangular and is horizontally installed inside the recess, with its top end flush with the bottom of the sewage treatment tank. Snap-fit ​​strips are fixed to both sides of the installation frame and slide into the snap-fit ​​grooves.

[0015] In detail, the fastening mechanism includes fastening bolts and connecting plates. One end of the sewage treatment tank has a mounting hole at its top. One end of the connecting plate overlaps the top of the mounting hole. Both ends of the connecting plate have connecting holes. A connecting bolt is threaded into one of the connecting holes and the other of the mounting holes. The fastening bolt passes through the other connecting hole and its bottom end abuts against the middle of the top of the mounting frame. The connecting plate is horizontally positioned.

[0016] In detail, the interior of the mounting groove has uniformly spaced discharge holes, the discharge pipe is connected to the outside of the discharge holes and is horizontally arranged, and the discharge holes inside the two mounting grooves are staggered with each other.

[0017] Core function: The motor drives the rotating rod to rotate in both directions, which in turn drives the moving plate to move back and forth along the guide rod at the top of the sewage treatment tank, and makes the medicine in the medicine tank evenly sprinkled into the sewage treatment tank.

[0018] The stirring blades are installed at the bottom of the moving plate via a support rod and a scraping frame. As the moving plate moves back and forth in the sewage treatment tank, the stirring blades and rotating sleeve can also rotate around the support rod, which can mix and stir the sewage and the chemical solution, and scrape and clean the sludge and impurities that have settled after sewage treatment through the scraping frame.

[0019] Two sets of staggered discharge pipes are connected to two mounting slots through discharge holes. Filter screens and mounting frames can be detachably installed inside the two mounting slots. Discharge pipes at different heights can be opened and closed by switching control valves, so that treated water can be discharged from different heights on the side of the sewage treatment tank.

[0020] After the filter screen is installed in the sewage treatment tank through the installation frame and installation groove, a receiving plate is fixed at the bottom of the installation frame. The receiving plate is set at the bottom of the filter screen to collect the impurities filtered out by the filter screen.

[0021] A connecting plate can be rotatably installed at the top of one end of the sewage treatment tank using connecting bolts. A tightening bolt is threaded onto the outer end of the connecting plate. After the filter screen is installed inside the sewage treatment tank through the mounting frame, the tightening bolt is rotated so that the bottom end of the tightening bolt is pressed against the top of the mounting frame, which facilitates the disassembly, installation, cleaning, and maintenance of the mounting frame and the filter screen.

[0022] The design scheme proposed in this utility model has the following beneficial effects in application:

[0023] 1. The stirring blades are set up by the moving plate and the scraping frame.
