Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment sedimentation device with a filter hole unblocking structure. Background Technology

[0002] With social development and industrial advancement, water scarcity and environmental pollution have become increasingly serious problems, making sewage and wastewater treatment increasingly important. Wastewater treatment processes generally combine natural sedimentation with biological aeration. Depending on the specific treatment steps, sedimentation tanks, anaerobic tanks, anoxic tanks, aerobic tanks, denitrification tanks, and micro-aeration tanks are required. Wastewater must flow sequentially through these tanks to purify harmful substances and meet discharge standards.

[0003] Chinese Patent Publication No. CN208785834U discloses a wastewater treatment sedimentation device, including a sedimentation tank wall, a wastewater collection pipe, a sedimentation tank baffle, a diversion channel, an outlet pipe, a sludge collection tank, and a discharge pipe. The beneficial effects of this invention are: by adding baffles to the sedimentation tank, the device stratifies the sedimentation tank, greatly increasing the contact area between the wastewater and the sedimentation tank to enhance the sedimentation effect. This solves the problem of large footprint of traditional sedimentation tanks, improving the efficiency of water purification. Simultaneously, the overall conical structure of the sedimentation tank enhances sedimentation efficiency while increasing the stability of the overall structure. The structure is simple, easy to use, and suitable for widespread application. However, the existing technical solution has the following shortcomings: while adding baffles to the sedimentation tank stratifies it and greatly increases the contact area between the wastewater and the sedimentation tank to enhance the sedimentation effect, the wastewater still contains impurities and debris after sedimentation, hindering subsequent utilization and purification. Therefore, certain improvements are needed. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sewage treatment sedimentation device with a filter hole unblocking structure, comprising a base, a sewage sedimentation tank installed at the top of the base, and an inlet pipe and a chemical inlet pipe respectively installed at the top of the sewage sedimentation tank; a purification tank installed on one side of the sewage sedimentation tank; a discharge pipe installed on the side of the inlet pipe away from the purification tank; a cleaning seat installed inside the purification tank, and a filter screen installed at the bottom of the cleaning seat; an unblocking structure is provided inside the cleaning seat to unblock the filter holes on the filter screen and prevent impurities from accumulating on the surface of the filter screen; a collection box is installed on one side of the purification tank; the purification tank and the sewage sedimentation tank are connected by a siphon pipe; the unblocking structure includes a second motor installed inside the cleaning seat; a threaded rod installed inside the cleaning seat, and a threaded sleeve installed on the outside of the threaded rod; an electric push rod installed at the bottom of the threaded sleeve; and a scraper and a second cleaning brush respectively installed at the bottom of the electric push rod.

[0006] When using a wastewater treatment sedimentation device with a filter hole unblocking structure according to this technical solution, the second motor is started through the unblocking mechanism during use, which can drive the cleaning component to move, thereby realizing the function of unblocking the filter holes and preventing a large amount of impurities from accumulating on the top of the filter screen, thus affecting the quality of subsequent wastewater filtration and purification.

[0007] Preferably, a locking block is installed on the side of the collection box near the sewage sedimentation tank, and a connecting block is installed on the side of the sewage sedimentation tank near the collection box, and the connecting block and the locking block are connected by a magnet.

[0008] Preferably, the connecting block is L-shaped, with its outer side conforming to the shape of the inner side of the card block.

[0009] Preferably, a flow-slowing mechanism is provided at the top of the inside of the sewage sedimentation tank. The flow-slowing mechanism includes a flow-slowing channel, which is located inside the sewage sedimentation tank. Obstruction protrusions are evenly installed inside the flow-slowing channel, and the flow-slowing channel is wavy in shape.

[0010] Preferably, an installation plate is installed inside the sewage sedimentation tank at the bottom of the slow-flow channel, and a first motor is installed inside the installation plate. A stirring rod is installed at the bottom of the installation plate, and stirring blades are evenly installed on both sides of the stirring rod. A first cleaning brush is installed on the outer side of each stirring blade.

[0011] Preferably, the stirring blades have an L-shaped cross-section and are arranged at equal intervals on both sides of the stirring rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the sewage treatment sedimentation device with filter hole unblocking structure not only realizes the function of filter hole unblocking structure, but also realizes the function of slow flow;

By setting up a dredging mechanism, starting the second motor and using the threaded connection, the threaded sleeve, the electric push rod at the bottom, and the cleaning components can be moved to achieve the function of dredging the filter holes, preventing a large amount of impurities from accumulating on the top of the filter screen, thereby affecting the quality of subsequent filtration and purification of sewage.

[0014] The second cleaning brush can initially clean the impurities accumulated on the surface of the filter screen. If hard impurities that are difficult to clean are encountered, the scraper behind the second cleaning brush can further clean the impurities.

[0015] The collection box can be fixed to one side of the sewage sedimentation tank by the interlocking action between the card block and the connecting block, so that staff can clean the garbage and impurities inside the collection box regularly.

[0016] 2. By setting up a slow-flow channel and with the cooperation of the obstruction protrusions, the flow rate of sewage can be buffered, thereby preventing a large amount of sewage from directly impacting down and mixing with the flocculant, which is not conducive to the full fusion reaction of the flocculant;

[0017] By setting the stirring blades in an L-shape, the flocculant can be fully mixed with the sewage and allowed to settle. At the same time, the first cleaning brush can prevent the sediment from adhering to the inner wall of the sewage sedimentation tank. Attached Figure Description
