Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an energy-saving and environmentally friendly wastewater treatment device. Background Technology

[0002] Wastewater generally refers to polluted wastewater from domestic and industrial processes. It mainly includes domestic sewage, industrial wastewater, and initial rainwater runoff. Major pollutants in wastewater include pathogens, oxygen-consuming pollutants, plant nutrients, and toxic pollutants. The core objective of wastewater treatment is to protect the environment and human health, and promote the recycling of water resources. Wastewater treatment can remove harmful substances such as nitrogen, phosphorus, and heavy metals from wastewater, prevent soil, water, and air pollution, and maintain ecological balance; restore the self-purification capacity of water bodies, ensuring the sustainable use of water resources; extract nutrients such as nitrogen and phosphorus from wastewater and convert them into fertilizers, reducing agriculture's dependence on chemical fertilizers; restore aquatic habitats and protect biodiversity; provide reliable water supply for cities, and promote sustainable economic and social development.

[0003] Referring to Chinese Patent Publication No. CN217961481U, with the publication date of December 6, 2022, an energy-saving and environmentally friendly sewage treatment device is disclosed. This utility model requires that after the water discharged from the sedimentation tank is filtered, when the filter plate needs to be cleaned, a reciprocating motor is started. Through the cooperation of a sliding plate, a threaded rod, and a trapezoidal plate, the surface impurities of the filter plate are cleaned and discharged to the outside through the channel formed by the fixed groove and the fixed plate.

[0004] However, existing energy-saving and environmentally friendly sewage treatment devices require the sliding plate to be moved by a threaded rod during use. Since sewage contains impurities, long-term sewage treatment can easily cause impurities to adhere to the outside of the threaded rod, leading to jamming and affecting the filtration effect of the filter plate. Furthermore, the water transported to the clean water tank after filtration contains suspended solids and requires further treatment. Therefore, there is still room for improvement.

[0005] Therefore, we propose an energy-saving and environmentally friendly wastewater treatment device to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an energy-saving and environmentally friendly sewage treatment device to solve the problems mentioned in the background art. In the process of using the existing energy-saving and environmentally friendly sewage treatment device, the sliding plate needs to be moved by the threaded rod. Since the sewage contains impurities, long-term sewage treatment can easily cause impurities to be adsorbed on the outside of the threaded rod, resulting in jamming and affecting the filtration effect of the filter plate. In addition, the water transported to the clean water tank after filtration contains suspended solids and needs further treatment. Therefore, there is still room for further improvement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and environmentally friendly wastewater treatment device, comprising: The treatment tank has a water inlet on its upper side, a guide plate on its left side, a collection tank below the guide plate, and a sedimentation tank on its lower side. Also includes: The processing box is equipped with a rinsing mechanism for cleaning the filter plate, and the filter plate is located inside the processing box. The sedimentation tank is equipped with a stirring mechanism to accelerate wastewater treatment, and the front side of the sedimentation tank is fixedly connected to the second motor via a support plate.

[0008] Preferably, the rinsing mechanism is composed of a first motor, a threaded rod, a connecting plate, a water supply pipe, a folding telescopic pipe, a high-pressure nozzle, and a limiting rod. The first motor is located on the right side of the treatment box, and the output shaft of the first motor is fixedly connected to the threaded rod, and the threaded rod is rotatably connected to the treatment box.

[0009] Preferably, the threaded rod is threadedly connected to the connecting plate, and the connecting plate is fixedly connected to the water supply pipe, and the upper side of the water supply pipe is fixedly connected to the folding telescopic pipe.

[0010] Preferably, a high-pressure nozzle is provided on the lower side of the water supply pipe, and the high-pressure nozzle is distributed in an array. The connecting plate is slidably connected to the limiting rod, and the limiting rod is fixedly connected to the treatment box.

[0011] Preferably, the stirring mechanism is composed of a drive belt, a pulley, a stirring shaft, and stirring blades.

In addition, a drain outlet is provided on the lower front side of the sedimentation tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the energy-saving and environmentally friendly sewage treatment device has a threaded rod set on the upper inner side of the treatment tank, and the sewage will not come into contact with the threaded rod after being added to the inside of the treatment tank. The limiting rod plays a limiting role on the connecting plate. The high-pressure nozzle performs high-pressure rinsing on the upper side of the filter plate, thereby achieving efficient filtration. The stirring shaft is rotated by the second motor, transmission belt and pulley, which facilitates the mixing of precipitant and sewage, thereby achieving environmentally friendly sewage treatment. 1. It is equipped with a treatment tank, a water inlet, and a filter plate. Wastewater is added to the treatment tank through the water inlet, and after being filtered by the filter plate, it is discharged into the sedimentation tank, thereby achieving the filtration of wastewater. 2. It is equipped with a threaded rod, a connecting plate and a limiting rod. The threaded rod is located on the upper inner side of the treatment tank, and the sewage will not come into contact with the threaded rod after being added to the inside of the treatment tank. This allows the connecting plate to move left and right with the water supply pipe inside the treatment tank. The limiting rod also limits the movement of the connecting plate. 3. It is equipped with a water supply pipe, a folding telescopic pipe and a high-pressure nozzle. The folding telescopic pipe is installed on the upper side of the water supply pipe.

Equipped with a guide plate, a collection box, and a sedimentation box, the debris on the upper part of the filter plate can be cleaned out by opening the box door on the left side of the treatment box. The inclined guide plate helps to collect the debris into the collection box for convenient centralized treatment. 5.

[0016] 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.

[0017] Please see Figures 1-5 As shown, this utility model provides a technical solution: an energy-saving and environmentally friendly sewage treatment device, including: a treatment tank 1, a water inlet 2, a filter plate 3, a first motor 4, a threaded rod 5, a connecting plate 6, a water supply pipe 7, a folding telescopic pipe 8, a high-pressure nozzle 9, a limiting rod 10, a guide plate 11, a collection tank 12, a sedimentation tank 13, a second motor 14, a transmission belt 15, a pulley 16, a stirring shaft 17, stirring blades 18, and a drain outlet 19.

[0018] In the operation of existing energy-saving and environmentally friendly sewage treatment devices, the sliding plate needs to be moved by the threaded rod 5. Since sewage contains impurities, long-term sewage treatment can easily cause impurities to be adsorbed on the outside of the threaded rod 5, causing jamming and affecting the filtration effect of the filter plate 3. In addition, the water transported to the clean water tank after filtration contains suspended solids and needs further treatment. Therefore, there is still room for further improvement.

[0019] like Figure 1 As shown, the initial stage of wastewater treatment is filtration. Wastewater to be treated is injected into the treatment tank 1 through the inlet 2 on the upper side. Under gravity, the wastewater falls naturally and flows through the inclined filter plate 3 inside the treatment tank 1. The filter plate 3 uses corrosion-resistant metal mesh or composite filter media, and its pore size is designed according to the particle size of impurities in the wastewater, effectively intercepting suspended particulate matter, fibrous impurities, and other solid pollutants in the wastewater.

[0020] The filter plate 3 is installed below the water inlet 2 and is fixed to the inner wall of the treatment tank 1 with bolts, which facilitates disassembly and replacement later. The filtered sewage flows into the sedimentation tank 13 through the pipe at the bottom of the treatment tank 1 that connects to the sedimentation tank 13, and enters the next treatment stage.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the filter plate 3 should be cleaned regularly. Open the maintenance door on the left side of the treatment box 1, and manually scrape off large or stubborn impurities accumulated on the surface of the filter plate 3 using tools. The scraped-off impurities will fall directly onto the guide plate 11. The guide plate 11 is designed to be inclined, and the impurities slide downwards along the plate surface and are initially collected into the collection box 12, avoiding large impurities from affecting the subsequent high-pressure rinsing effect.

[0022] like Figure 1 and Figure 2 As shown, the first motor 4 is started, and its output shaft drives the threaded rod 5 to rotate inside the upper part of the processing box 1 via a coupling. Since the threaded rod 5 is threadedly connected to the connecting plate 6, and the connecting plate 6 is sleeved on the limiting rod 10, wherein the limiting rod 10 is parallel to the threaded rod 5 and fixed to the inner wall of the processing box 1, under the limiting action of the limiting rod 10, the connecting plate 6 reciprocates horizontally along the axial direction of the threaded rod 5.

[0023] The connecting plate 6 drives the water supply pipe 7 to move synchronously. The folding telescopic pipe 8 on the upper side of the water supply pipe 7 can freely extend and retract with the movement. The folding telescopic pipe 8 is connected to an external high-pressure water source to ensure a continuous and stable water supply. The high-pressure nozzle 9 on the lower side of the water supply pipe 7 sprays high-pressure water onto the surface of the filter plate 3 to thoroughly wash away any remaining fine impurities.

[0024] like Figure 1 and Figure 5 As shown, the filtered wastewater flows into the sedimentation tank 13 through the bottom pipe of the treatment tank 1. At this time, a flocculant such as polyaluminum chloride or ferrous sulfate needs to be added, which can be done through the water inlet 2. The mixing reaction is accelerated by the stirring mechanism. The second motor 14 is started, and the drive pulley 16 on its output shaft drives the driven pulley 16 on the front of the stirring shaft 17 to rotate through the transmission belt 15. The stirring blades 18 are provided on the outside of the stirring shaft 17, which push the wastewater to form a circulation, so that the flocculant and wastewater are fully mixed, accelerating the agglomeration of suspended solids into large particles and improving the sedimentation efficiency.

[0025] After being stirred and reacted, the wastewater in sedimentation tank 13 is allowed to settle. The clear water at the top is discharged through the drain outlet 19 with a valve at the bottom front of sedimentation tank 13. Once it meets the standards, it can be recycled or discharged. The settled sludge is discharged after being cleaned with a high-pressure water gun through the door on the right side of sedimentation tank 13, completing the entire wastewater treatment process.

[0026] The contents not described in detail in this specification are existing technologies known to those skilled in the art. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
