Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an urban wastewater treatment device. Background Technology

[0002] Urban sewage typically refers to wastewater generated during the daily life of urban residents, commercial activities, industrial production, and operation of public facilities. It needs to be treated by sewage treatment equipment before it can be discharged. In addition, since this type of sewage contains floating objects such as solid garbage, it usually needs to be filtered first to prevent clogging of the sewage treatment equipment.

[0003] For example, a municipal wastewater treatment device with application number CN202420733094.2 includes a sedimentation tank, a filter box, a through hole one, a chute, a collection box, a filter box, a through hole two, and a through hole one. Fixed garbage in the wastewater is blocked, and the wastewater is separated from suspended solids and some organic matter by natural gravity, forming sludge that settles at the bottom of the sedimentation tank. Opening multiple valves allows the settled wastewater to flow into the interior of the purification tank through multiple outlet pipes. An installation groove is provided at the upper end of the purification tank, and a filter screen box is movably embedded inside the installation groove. The filter screen box is filled with activated carbon particles, which can adsorb residual organic matter and toxic and harmful substances in the wastewater, thereby improving the quality of the wastewater.

[0004] The aforementioned wastewater treatment device filters and screens impurities in untreated wastewater by pouring it into a filter box. However, since the filter screen in the filter box is integrally formed and only has a single layer, the filtration effect is poor. Furthermore, if the filter screen opening is damaged, it cannot be replaced individually, making it inconvenient to use.

[0005] Therefore, we propose an urban wastewater treatment device to address the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide an urban sewage treatment device to solve the problems mentioned in the background art, which are that the filter screen in the filter box is integrally formed and only a single layer is provided, resulting in poor filtration effect. In addition, if the filter screen opening is damaged, it cannot be replaced individually, which is inconvenient to use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a city sewage treatment device, comprising a mounting component and a sedimentation tank fixedly installed at the lower end of the mounting component. A drive motor is fixedly installed on one side of the outer wall of the sedimentation tank, and a threaded rod is installed at the output end of the drive motor. A cleaning plate is threadedly connected to the outer surface of the threaded rod. Multiple drainage pipes are linearly and equally spaced at the lower end of one side of the outer wall of the sedimentation tank. A purification tank is provided at the lower end of the drainage pipes. A screening component is magnetically installed in the inner cavity of the mounting component. The screening component is set to be suitable for filtering impurities in the sewage.

[0008] The screening component includes a support mechanism and a detachable mechanism magnetically connected to the inner cavity of the support mechanism.

[0009] Preferably, the placement component includes a hollow storage frame and hollow magnetic boxes that are respectively fixedly installed on the middle of both sides of the outer wall of the hollow storage frame.

[0010] Preferably, the support mechanism includes a hollow box and a herringbone-shaped patch fixedly installed around the lower end of the inner wall of the hollow box, with a magnetic sticker embedded in the upper end of the herringbone-shaped patch.

[0011] Preferably, concave inserts are fixedly installed on the middle of the upper two sides of the hollow box, and corresponding magnetic stickers are embedded in the lower end of one side of the outer wall of the concave insert, and a lifting block is fixedly installed on the upper end of one side of the outer wall of the concave insert.

[0012] Preferably, the detachable mechanism includes a magnetic base frame and a cross-shaped card holder fixedly installed in the middle of the inner cavity of the magnetic base frame, with a first filter layer embedded in the upper periphery of the cross-shaped card holder.

[0013] Preferably, extension rods are threadedly installed at the four upper corners of the magnetic bottom frame and the middle of the upper part of the cross bracket. A T-shaped threaded rod is fixedly installed at the upper end of the extension rod. A second frame is threadedly installed at the upper end of the magnetic bottom frame. Circular grooves are opened at the four upper corners and the middle of the upper part of the second frame. A second filter screen is embedded in the upper part of the second frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By using the hollow storage frame, first filter layer, second filter screen, magnetic bottom frame, and U-shaped adhesive block, the magnetic bottom frame can be removed from the top of the hollow box to clean the blockage of the first filter layer and the second filter screen. By removing the nut that is threaded to the top of the T-shaped threaded rod, the second frame can be removed from the top of the magnetic bottom frame, thereby replacing the damaged filter screen.

[0016] 2. The design of the first filter layer, second filter screen, lifting block, concave insert block, hollow box and hollow storage frame makes it less likely for operators to come into contact with sewage when taking out the hollow box, thus improving the hygiene of the operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figures 1-3A city sewage treatment device includes a mounting component 1 and a sedimentation tank 2 fixedly installed at the lower end of the mounting component 1. A drive motor 3 is fixedly installed on one side of the outer wall of the sedimentation tank 2. A threaded rod 4 is installed at the output end of the drive motor 3. A cleaning plate 5 is threadedly connected to the outer surface of the threaded rod 4. One end of the cleaning plate 5 is guided to move by a guide rod. Multiple drain pipes 6 are linearly and equally spaced at the lower end of one side of the outer wall of the sedimentation tank 2. A purification tank 7 is set at the lower end of the drain pipes 6. The purification tank 7 can be used to add agents to treat bacteria in sewage. A screening component 8 is magnetically installed in the inner cavity of the mounting component 1. The screening component 8 is set to filter impurities in sewage.

[0024] The drive motor 3 is configured to drive the threaded rod 4 to rotate, thereby moving the cleaning plate 5 that is threaded onto the outer surface of the threaded rod 4, thus scraping the impurities settled at the bottom of the sedimentation tank 2.

[0025] The screening component 8 includes a support mechanism 81 and a detachable mechanism 82 magnetically connected to the cavity of the support mechanism 81.

[0026] The placement component 1 includes a hollow storage frame 11 and hollow magnetic boxes 12 that are respectively fixedly installed on the middle of the outer walls of the hollow storage frame 11 on both sides.

[0027] The detachable mechanism 82 includes a magnetic bottom frame 821 and a cross-shaped card holder 822 fixedly installed in the middle of the inner cavity of the magnetic bottom frame 821. A first filter layer 823 is embedded in the upper circumference of the cross-shaped card holder 822.

[0028] Extension rods 824 are threadedly installed at the four upper corners of the magnetic base frame 821 and at the middle of the upper part of the cross bracket 822. T-shaped threaded rods 825 are fixedly installed at the upper end of the extension rods 824. A second frame 826 is threadedly installed at the upper end of the magnetic base frame 821. Circular grooves 827 are opened at the four upper corners and the middle of the upper part of the second frame 826.

[0029] The upper end of the second frame 826 is fitted with a second filter screen 828. The T-shaped threaded rod 825 is movably installed in the inner cavity of the circular groove 827 and is fixed by a nut, so that the second frame 826 is threadedly connected to the upper end of the magnetic bottom frame 821. This arrangement makes it easy to separate the second frame 826 and the magnetic bottom frame 821.

[0030] The first filter layer 823 and the second filter screen 828 are designed to be suitable for double-layer filtration of garbage in sewage. At the same time, a filter screen (not shown in the figure) is provided at the bottom of the hollow storage frame 11, which can improve the filtration effect of the hollow storage frame 11 itself.

[0031] In this embodiment: when sewage is discharged into the inner cavity of the hollow storage frame 11, it is subjected to double filtration by the first filter layer 823 and the second filter screen 828, and then injected into the inner cavity of the sedimentation tank 2 through the filter screen set at the bottom of the hollow storage frame 11 for sedimentation. After the first filter layer 823 and the second filter screen 828 become clogged after long-term use, the hollow box 811 is first removed from the inner cavity of the hollow storage frame 11, and at the same time, the bottom of the magnetic bottom frame 821 is directly magnetically adsorbed onto the hollow box. By attaching the U-shaped patch 812 and magnetic patch 813 at the top of the hollow box 811, the magnetic bottom frame 821 can be directly removed from the top of the box 811 to clean the blockage of the first filter layer 823 and the second filter screen 828. At the same time, if the first filter layer 823 and the second filter screen 828 are damaged, the second frame 826 can be removed from the top of the magnetic bottom frame 821 by removing the nut that is threaded to the top of the T-shaped threaded rod 825, so that the damaged filter screen can be replaced. It is convenient to use.

[0032] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 The support mechanism 81 includes a hollow box 811 and a herringbone-shaped patch 812 fixedly installed around the lower end of the inner wall of the hollow box 811. A magnetic patch 813 is embedded in the upper end of the herringbone-shaped patch 812.

[0033] A concave insert 814 is fixedly installed on the middle part of the upper two sides of the hollow box 811. A corresponding magnet 815 is embedded in the lower end of one side of the outer wall of the concave insert 814. A lifting block 816 is fixedly installed on the upper end of one side of the outer wall of the concave insert 814. The corresponding magnet 815 and the hollow magnetic box 12 are magnetically connected to improve the stability of the concave insert 814 in the upper two sides of the hollow storage frame 11.

[0034] Pulling the lifting block 816 can remove the concave insert block 814 and the hollow box 811 from the inner cavity of the hollow storage frame 11.

[0035] In this embodiment: after the first filter layer 823 and the second filter screen 828 become clogged after long-term use, the concave insert 814 and the hollow box 811 are taken out from the inner cavity of the hollow storage frame 11 by pulling the lifting block 816. Since the lifting block 816 is set on the outer wall of the concave insert 814, this setting makes it less likely for the operator's hands to come into contact with sewage when taking out the hollow box 811, thus improving the hygiene of the operation.

[0036] Working principle: When sewage enters the inner cavity of the hollow storage frame 11, it undergoes double filtration by the first filter layer 823 and the second filter screen 828. The sewage then flows through the filter screen at the bottom of the hollow storage frame 11 into the inner cavity of the sedimentation tank 2 for sedimentation. After prolonged use, if the first filter layer 823 and the second filter screen 828 become clogged, pulling the lifting block 816 will remove the concave insert block 814 and the hollow box 811 from the inner cavity of the hollow storage frame 11. Since the lifting block 816 is located on the outer wall of the concave insert block 814, this design facilitates easy removal of the hollow box 811 by the operator. This design minimizes hand contact with wastewater, improving operational hygiene. Furthermore, the bottom of the magnetic base frame 821 is directly magnetically attached to the U-shaped adhesive block 812 and magnetic adhesive pad 813 on the upper end of the hollow box 811, allowing the magnetic base frame 821 to be easily removed from the upper end of the hollow box 811 for cleaning the first filter layer 823 and the second filter screen 828. Additionally, if the first filter layer 823 or the second filter screen 828 is damaged, the second frame 826 can be removed from the upper end of the magnetic base frame 821 by disassembling the nut threaded onto the T-shaped threaded rod 825, thus allowing for the replacement of the damaged filter screen.
