Description

Technical Field

[0001] This application belongs to the technical field of water treatment equipment, and in particular relates to a PPH sedimentation tank that can recycle resources. Background Technology

[0002] PPH sedimentation tanks are large water tanks made primarily of PPH material used for sedimentation. Due to the special chemical properties of PPH material, such as corrosion resistance and acid resistance, it is widely used in industrial water tanks. PPH sedimentation tanks are generally used to remove harmful substances from wastewater. After multiple filtrations and sedimentation of the wastewater, the clean water is discharged from the outlet. Due to long-term use, the substances that settle at the bottom will affect the efficiency of the PPH sedimentation tank if they are not cleaned regularly. Regular cleaning of the sediment at the bottom is necessary.

[0003] For example, Chinese utility model patent CN219167930U discloses a PPH sedimentation tank for wastewater treatment with cleaning function, which includes an inlet connected to the main body of the PPH sedimentation tank, an outlet connected to the main body of the PPH sedimentation tank, and a sedimentation plate fixedly connected inside the main body of the PPH sedimentation tank.

[0004] Although the above solution can concentrate impurities and sediments through the sedimentation plate installed in the main body of the PPH sedimentation tank, making it easier for subsequent cleaning, the sewage generally contains a lot of sludge. After a long period of operation, some sludge will stick to the smooth parts of the sedimentation plate, and the mesh parts of the sedimentation plate will also be blocked by sludge, thus affecting the subsequent sewage treatment effect of the equipment. Utility Model Content

[0005] To address the technical problem that after prolonged operation of the equipment in the solution, some sludge will adhere to the smooth parts of the sedimentation plate, and the mesh parts of the sedimentation plate will become clogged with sludge, thus affecting the subsequent sewage treatment effect of the equipment, this utility model provides a PPH sedimentation tank that allows for resource recycling.

[0006] In a first aspect, this application provides a PPH settling tank capable of resource recovery, comprising: The sedimentation tank body has an outlet on its horizontally parallel side and an inlet on its vertically parallel side. The slag and sludge removal mechanism further includes: two sets of sprockets, chains and multiple scrapers. The two sets of sprockets are installed inside the sedimentation tank body. Each set of sprockets is connected to the other by chain drive. The multiple scrapers are fixed to the outside of the two sets of chains. A slag discharge trough is fixed to the outer side of the sedimentation tank body, which is vertically parallel to it. A sludge collection box is fixed to the vertical parallel side of the sedimentation tank body.

[0007] According to an embodiment of this application, a PPH sedimentation tank capable of resource recycling is provided. By introducing wastewater into the sedimentation tank body through the inlet, and then allowing it to settle naturally, the sludge in the wastewater will fall to the bottom of the sedimentation tank body due to gravity, while the scum in the wastewater will float on the water surface. At this time, through the cyclic rotation of the scraper in the sludge removal mechanism, the scum is pushed into the sludge discharge trough while the sludge on the bottom of the sedimentation tank body is scraped off and pushed into the sludge collection box.

[0008] According to one embodiment of this application, the PPH sedimentation tank capable of resource recycling further includes a symmetrically arranged rotating shaft rotatably connected between two inner sides of the sedimentation tank body, and the sprocket is fixed to the outer side of the rotating shaft. The sedimentation tank body is horizontally parallel to one of the outer sides, where a servo motor is fixedly connected coaxially with one of the rotating shafts.

[0009] According to one embodiment of this application, the sludge collection box and the sedimentation tank body are provided with a discharge port on the same side bottom end, and a suction pipe is provided on the side of the sludge collection box away from the sedimentation tank body.

[0010] According to one embodiment of this application, the bottom of the sludge collection box is inclined, and the highest point of the inclined bottom of the sludge collection box is flush with the bottom of the sedimentation tank body.

[0011] According to one embodiment of this application, a slag discharge port is provided on the same side of the slag discharge tank and the sedimentation tank body, and the slag discharge port is slightly higher than the water level inside the sedimentation tank body.

[0012] According to one embodiment of this application, a plurality of inclined baffles are provided between the two inner sides of the sedimentation tank body in a horizontal parallel manner, and the inclination angle of the baffles is 60 degrees.

[0013] Secondly, this application provides a PPH sedimentation tank capable of resource recovery; Including at least one of the following beneficial technical effects: 1. This application introduces wastewater into the sedimentation tank body through the inlet, and after natural sedimentation, the sludge in the wastewater will fall to the bottom of the sedimentation tank body due to gravity, and the scum in the wastewater will float on the water surface; at this time, the scraper in the sludge removal mechanism rotates clockwise, pushing the scum into the sludge discharge trough while scraping off the sludge on the bottom of the sedimentation tank body and pushing it into the sludge collection box for subsequent recycling, turning waste into treasure.

[0014] 2. This application improves the efficiency of sludge and scum stratification in wastewater by setting multiple baffles at an inclination angle of 60 degrees inside the sedimentation tank body, forming an independent sedimentation space between each pair of adjacent baffles. The area of ​​this sedimentation space is much larger than the sedimentation area at the bottom of the sedimentation tank body, and the settling distance of sludge is greatly shortened.

[0015] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0017] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0018] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example 1: This embodiment specifically describes the structure of a PPH sedimentation tank capable of resource recovery, such as... Figures 1-3 As shown, it includes four structural parts: sedimentation tank body 1, sludge scraping and sludge removal mechanism 2, sludge discharge tank 3, and sludge collection box 4; The sedimentation tank body 1 has an outlet 101 on its horizontally parallel side and an inlet 102 on its vertically parallel side. The slag and mud removal mechanism 2 further includes: two sets of sprockets 201, chains 202 and multiple scrapers 203. The two sets of sprockets 201 are installed inside the sedimentation tank body 1. Each set of sprockets 201 is connected to each other by chains 202. Multiple scrapers 203 are fixed to the outside of the two sets of chains 202. Slag discharge trough 3 is fixed to the outside of the sedimentation tank body 1, which is vertically parallel to it. Sludge collection box 4 is fixed to the vertical parallel side of sedimentation tank body 1.

[0019] The entire PPH sedimentation tank treatment process is as follows: wastewater is introduced into the sedimentation tank body 1 through the inlet 102, and after natural sedimentation, the sludge in the wastewater will fall to the bottom of the sedimentation tank body 1 due to gravity, and the scum in the wastewater will float on the water surface. At this time, the scraper 203 in the sludge removal mechanism 2 will rotate in a cycle, pushing the scum into the discharge tank 3 while scraping off the sludge at the bottom of the sedimentation tank body 1 and pushing it into the sludge collection box 4.

[0020] In some examples, combined Figure 1 and Figure 3 A PPH sedimentation tank capable of resource recycling also includes a sedimentation tank body 1 with two symmetrically arranged rotating shafts 5 rotatably connected between its two inner sides, and a sprocket 201 fixed to the outer side of the rotating shaft 5. A servo motor 6, which is coaxially connected to one of the rotating shafts 5, is fixed to the outer side of the sedimentation tank body 1, which is parallel to the side.

[0021] In some examples, the sludge collection box 4 and the sedimentation tank body 1 are provided with a discharge port 401 on the same side bottom end, and a suction pipe 402 is provided on the side of the sludge collection box 4 away from the sedimentation tank body 1.

[0022] In some examples, the bottom of the sludge collection box 4 is inclined, and the highest point of the inclination of the bottom of the sludge collection box 4 is flush with the bottom of the sedimentation tank body 1.

[0023] In some examples, the slag discharge trough 3 and the sedimentation tank body 1 are provided with a slag discharge port 301 on the same side, and the slag discharge port 301 is slightly higher than the water level inside the sedimentation tank body 1.

[0024] By adopting the above technical solution: valves are installed at both the discharge port 401 and the slag discharge port 301. Before introducing sewage into the sedimentation tank body 1, the valves at both the discharge port 401 and the slag discharge port 301 are closed. Then, the sewage is injected into the sedimentation tank body 1 through the inlet 102 until the sewage level reaches the slag discharge port 301. At this time, after a period of natural sedimentation and stratification, the sludge in the sewage will fall to the bottom of the sedimentation tank body 1 due to gravity, and the scum in the sewage will float on the water surface. At this time, the valves at the servo motor 6, the discharge port 401 and the slag discharge port 301, as well as the pump body connected to the external suction pipe 402 are opened simultaneously. The valve at the discharge port 401 is opened and closed intermittently according to the scraping of the scraper 203. The activation of the servo motor 6 drives one of the rotating shafts 5 to rotate. Since multiple rotating shafts 5 are connected through two sets of sprockets 201 and chains 202, the rotation of one rotating shaft 5 drives the other rotating shafts 5 to rotate synchronously. This causes multiple scrapers 203 fixed to the outside of the chain 202 to rotate clockwise. The scraper 203 at the top can push the scum through the scum discharge port 301 into the scum discharge trough 3. The scraper 203 at the bottom can scrape off the sludge on the bottom of the sedimentation tank body 1 and push it through the discharge port 401 into the sludge collection box 4. Since the bottom of the sludge collection box 4 is set in an inclined state, and the highest point of the sludge collection box 4 is flush with the bottom of the sedimentation tank body 1, the sludge will accumulate below the suction pipe 402 for easy suction.

[0025] Example 2: Combination Figure 1 and Figure 2 This embodiment specifically describes the structure of the partition 7. In some examples, multiple inclined baffles 7 are provided between the two inner sides of the sedimentation tank body 1 in a horizontal parallel manner, and the inclination angle of the baffles 7 is 60 degrees.

[0026] By adopting the above technical solution: Multiple baffles 7 with an inclination angle of 60 degrees are set inside the sedimentation tank body 1. Each pair of adjacent baffles 7 forms an independent sedimentation space. The sedimentation space area composed of multiple such sedimentation spaces is much larger than the sedimentation area at the bottom of the sedimentation tank body 1. This greatly shortens the sludge settling distance in each wastewater, allowing it to settle onto the baffles 7 with an inclination angle of 60 degrees in a shorter time, and finally fall to the bottom of the sedimentation tank body 1 for centralized collection. At the same time, the scum in the sewage will float to the surface of the water, which can greatly improve the efficiency of sludge and scum separation in the sewage.

[0027] The working principle of a PPH sedimentation tank capable of resource recycling in this application embodiment is as follows: Wastewater is introduced into the sedimentation tank body 1 through inlet 102. After natural sedimentation, the sludge in the wastewater will fall to the bottom of the sedimentation tank body 1 due to gravity, while the scum in the wastewater will float on the water surface. At this time, the scraper 203 in the sludge removal mechanism 2 will rotate to push the scum into the discharge trough 3 and scrape off the sludge at the bottom of the sedimentation tank body 1 and push it into the sludge collection box 4. The sludge is then extracted by the suction pipe 402, and the scum in the discharge trough 3 is recycled, realizing the transformation of waste into treasure and recycling.
