Description

Technical Field

[0001] This utility model relates to the field of sewage treatment, and in particular to a domestic sewage treatment and purification device. Background Technology

[0002] In rural areas, most households dump untreated domestic sewage into ditches, fields, or onto crops. This sewage contains various pollutants such as residue, oil, and pathogens, which can negatively impact crop growth. Therefore, treatment is necessary. Since rural areas have abundant sunlight, there are no tall buildings to block it. Utilizing this sunlight can help eliminate pathogens in the sewage. Currently, a simple filtration and disinfection process is used in a disinfection pool before discharge. However, this method is highly susceptible to environmental influences, and the presence of oil on the sewage surface hinders sunlight penetration, severely impacting the disinfection effectiveness. The discharge of this incompletely treated sewage damages the original rural ecological environment and negatively affects farmers' lives. Utility Model Content

[0003] In order to overcome the shortcomings of the disinfection effect being greatly affected by the environment and the disinfection effect being affected by oil pollution in the disinfection pool, this utility model provides a domestic sewage treatment and purification device.

[0004] The technical solution of this utility model is as follows: a domestic sewage treatment and purification device, including a sewage tank and a cover plate installed on the sewage tank; it also includes an oil scraping assembly, which includes a drive unit; the drive unit is installed on the upper side of the sewage tank; a collection box for collecting oil stains on the surface of the sewage is fixedly connected to the drive unit; a scraper is installed on the upper side of the collection box; two electric winding devices are symmetrically arranged at both ends of the slider, and a pull rope is connected to the electric winding device; an oil tank for receiving and treating oil stains in the collection box is fixedly connected to one end of the sewage tank.

[0005] Furthermore, the cover plate is arc-shaped and made of transparent material; several light-concentrating spheres are set on both sides of the cover plate, and the light-concentrating spheres are transparent.

[0006] Furthermore, the drive unit includes a first drive component, a slider, and a second drive component. Two first drive components are symmetrically arranged on both sides of the sewage tank; the same slider is slidably connected to the two first drive components; the second drive component can drive the collection box to move up and down.

[0007] Furthermore, a rotating shaft and a rotating plate are provided on the lower side of the collection box; the rotating plate can rotate with the rotating shaft, and several magnetic strips are provided on the rotating shaft and the collection box.

[0008] Furthermore, the scraper is tilted; the scraper is made of soft material that can be squeezed and deformed under external force; under the action of the electric rewinder, the pull rope on the electric rewinder can be tightened, the pull rope is connected to the scraper, and the pull rope can lift the scraper at the end away from the collection box.

[0009] Furthermore, the oil tank is equipped with an opening strip, which can separate the rotating plate and the collection box when the collection box is moved into the oil tank; the oil tank is also equipped with a hole for draining the oil-water mixture.

[0010] Furthermore, it also includes an adsorption assembly, which includes a roller, an adsorption bag, and a counterweight; the roller is fixed to the slider; the adsorption bag for adsorbing pigments in the sewage tank is installed on the roller; and a counterweight is provided at the unrolled end of the adsorption bag.

[0011] Furthermore, a layer of wood ash is placed inside the adsorption bag.

[0012] In addition to oil stains, domestic sewage from farmers also contains color. During the sewage purification process, the color of the water can greatly affect the water's efficiency in absorbing sunlight. This color may come from detergents, kitchen waste water, or even artificial pigments left on clothing. If these substances are used for irrigation, they will affect crop growth.

[0013] To address the aforementioned issues, while the first driving component moves the oil scraping assembly towards the oil tank, the reel rotates, unwinding the adsorption bag from its wound state. Due to the counterweight, one end of the adsorption bag rests at the bottom of the wastewater tank. As the first driving component continues to move, the adsorption bag fully unfolds, making full contact with the wastewater. After the adsorption bag has been unwound for a certain period, pigment adsorption is complete, and the reel rotates, causing the adsorption bag to rewind back to its initial wound state. The entire process is simple to operate and highly effective. By using the movement of the first driving component to ensure full contact between the adsorption assembly and the wastewater, the problem of wastewater color is solved, ensuring the normal efficiency of sunlight absorption by the wastewater and reducing the impact of the wastewater itself on the purification process.

[0014] Beneficial effects: This utility model achieves the collection of oil stains on the surface of sewage by scraping oil with a scraper and collecting oil with a collection box, thereby reducing the impact of oil stains on light.

[0015] By winding and unwinding the adsorption bag, pigments in wastewater are removed, the light transmittance of the wastewater is increased, and the disinfection of wastewater is facilitated. Attached Figure Description

Detailed Implementation

[0018] 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.

[0019] Example 1: A domestic sewage treatment and purification device, such as... Figures 1-5 As shown, it includes a sewage tank 1 and a cover plate 2; 1-The sewage tank 1 is equipped with a cover plate 2; It also includes an oil scraping assembly, which includes a drive unit, a collection box 104, a scraper 105, an electric winder 106, and an oil tank 107. The drive unit is installed on the upper side of the sewage tank 1. The collection box 104 is fixedly connected to the drive unit. The scraper 105 is installed on the upper side of the collection box 104. Two electric winders 106 are symmetrically arranged at both ends of the slider 102. Pull ropes are connected to the electric winders 106. The pull ropes at both ends are connected to the scraper 105 and can lift the scraper 105 at the end away from the collection box 104. An oil tank 107 is fixedly connected to one end of the sewage tank 1.

[0020] The cover plate 2 is arc-shaped and made of transparent material, which can reduce the impact of the external environment on sewage. Several light-concentrating balls 2001 are set on both sides of the cover plate 2. The light-concentrating balls 2001 are transparent, which can concentrate more sunlight into the sewage tank 1, increase the ultraviolet rays in the sewage tank 1, and speed up the sewage treatment process.

[0021] The drive unit includes a first drive component 101, a slider 102, and a second drive component 103; the first drive component 101 is an electric slide rail, and the second drive component 103 is an electric push rod; two first drive components 101 are symmetrically arranged on both sides of the sewage tank 1; the same slider 102 is slidably connected to the two first drive components 101; the second drive component 103 can drive the collection box 104 to move up and down to adapt to sewage of different water levels.

[0022] A rotating shaft 10401 and a rotating plate 10402 are provided on the lower side of the collection box 104. The rotating plate 10402 can rotate with the rotating shaft 10401, and several magnetic strips 10403 are provided on the rotating shaft 10401 and the collection box 104, so that the rotating plate 10402 is attached to the lower side of the collection box 104 to prevent the collected oil from overflowing.

[0023] The scraper 105 is tilted; the scraper 105 is made of soft material and can be squeezed and deformed under external force; under the action of the electric rewinder 106, the pull rope on the electric rewinder 106 can be tightened, so that the oil-water mixture remaining on the surface of the scraper 105 slides into the collection box 104.

[0024] An opening strip 10701 is provided inside the oil tank 107. When the collection box 104 moves into the oil tank 107, the opening strip 10701 can separate the rotating plate 10402 and the collection box 104, so that the oil-water mixture in the collection box 104 is poured into the oil tank 107, so that the scraper 105 can scrape the oil-water mixture in the next round. The oil tank 107 is provided with a hole for discharging the oil-water mixture.

[0025] In rural areas, most domestic sewage from farmers is dumped untreated into ditches, fields, or onto crops. This sewage contains various pollutants such as residue, oil, and pathogens, which negatively impact crop growth. Therefore, treatment is necessary. Since rural areas have abundant sunlight, there are no tall buildings to block it. Utilizing this sunlight can help eliminate pathogens in the sewage. Currently, a simple filtration and disinfection process is used in a disinfection pool before discharge. However, this method is highly susceptible to environmental influences, and the presence of oil on the sewage surface hinders sunlight penetration, severely impacting the disinfection effect. The discharge of this incompletely treated sewage damages the original rural ecological environment and affects farmers' lives.

[0026] To solve the above problems, a cover plate 2 is installed on the sewage tank 1. On both sides of the cover plate 2, there are several light-concentrating spheres 2001 for collecting scattered light. This cover plate 2 can reduce the impact of the external environment on the sewage to be treated in the sewage tank 1, and can collect some of the scattered light in the environment into the sewage tank 1 through the light-concentrating spheres 2001, thereby accelerating the sterilization effect.

[0027] Domestic sewage enters sewage tank 1 through inlet 1001. After standing for a period of time, the slider 102 is located on the side away from the oil tank 107. The controller remotely starts the second drive unit 103 to move the collection box 104 and scraper 105 downwards until the scraper 105 is partially submerged in the water and no sewage flows into the collection box 104. At this time, the first drive unit 101 moves the slider 102 towards the oil tank 107. Due to the inclined setting of the scraper 105, the oil-water mixture on the scraper 105 will temporarily rise above the sewage tank during the movement of the scraper 105. At the water surface, the oil-water mixture on the top layer of the sewage can flow along the upper surface of the scraper 105 into the collection box 104, thus collecting the oil. When the scraper 105 touches the inner wall of the sewage tank 1 near the oil tank 107, the first drive unit 101 temporarily stops moving, and the electric retractor 106 rotates to tighten the pull rope. The scraper 105 on the side away from the collection box 104 is lifted by the pull rope, and the remaining flowable oil-water mixture on the scraper 105 slides into the collection box 104. Subsequently, the second drive unit 103 drives the scraper 105 and the collection box 104 to move upward, and the collection box 104... 4 and its related parts continue to move towards the oil tank 107, passing over the side wall of the sewage tank 1; one end of the opening strip 10701 is pointed and can be stuck between the rotating plate 10402 and the collection box 104. As the collection box 104 and its related parts continue to move, the rotating plate 10402 and the collection box 104, which were originally in contact, will separate due to the action of the opening strip 10701. Since the distance between the rotating plate 10402 and the collection box 104 is relatively large after they separate, the attraction of the magnetic strip 10403 no longer supports their contact; due to gravity, the rotating plate 10402 follows the rotating shaft 1 Rotate 0401 to pour the oil from the collection box 104 into the oil tank 107; at the same time, the thin line on the electric rewinder 106 loosens, and the scraper 105 returns to its initial state; after the pouring is complete, the oil scraping assembly moves away from the oil tank 107, and the rotating plate 10402 and the collection box 104 are tightly attached to each other due to the side wall of the sewage tank 1 and the magnetic strip 10403; the whole process is simple to operate and has significant effects, which can not only reduce the interference of the external environment on the sewage sterilization process, but also scrape off the oil on the surface of the sewage tank 1, ensuring that the light is not blocked by the oil.

[0028] Example 2, based on Example 1, such as Figures 1-6 As shown, it also includes an adsorption assembly, which includes a roller 201, an adsorption bag 202, and a counterweight 203; the roller 201 is fixedly connected to the slider 102; the adsorption bag 202 is installed on the roller 201, and a layer of wood ash is provided inside the adsorption bag 202 to allow the adsorption bag 202 to have a larger contact area with the sewage and accelerate the adsorption of pigments; a counterweight 203 is provided at the unrolled end of the adsorption bag 202.

[0029] In addition to oil stains, domestic sewage from farmers also contains color. During the sewage purification process, the color of the water can greatly affect the water's efficiency in absorbing sunlight. This color may come from detergents, kitchen waste water, or even artificial pigments left on clothing. If these substances are used for irrigation, they will affect crop growth.

[0030] To solve the above problems, while the first driving component 101 drives the oil scraping assembly to move towards the oil tank 107, the roller 201 rotates, unwinding the adsorption bag 202 from its wound state. Due to the action of the counterweight 203, one end of the adsorption bag 202 will fall to the bottom of the sewage tank 1. With the continuous movement of the first driving component 101, the adsorption bag 202 can be fully unfolded and fully contacted with the sewage. After the adsorption bag 202 has been unwound for a certain period of time, the pigment adsorption is completed, and the rotation of the roller 201 drives the adsorption bag 202 to rewind, returning to the initial wound state. The whole process is simple to operate and has obvious effects. By moving the first driving component 101 to drive the adsorption assembly to fully contact the sewage, the problem of the sewage having color is solved, the normal efficiency of the sewage absorbing sunlight is ensured, and the impact of the sewage itself on the purification process is reduced.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
