Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a coal chemical industry wastewater treatment catalyst recovery device. Background Art

[0002] The main pollutants in coal chemical wastewater are phenol and ammonia. There are also more than 300 kinds of pollutants, such as tar, phenol, cyanide, sulfide, COD, etc., which will inevitably increase the toxicity of coal chemical wastewater, which also brings great difficulties to wastewater treatment and zero discharge.

[0003] When treating coal chemical wastewater, organic matter is added for treatment. In order to promote the decomposition and oxidation of organic matter, catalysts are added. The wastewater treatment catalyst can quickly convert organic pollutants, color, odor and other harmful substances in the wastewater into harmless substances such as carbon dioxide and water through the oxidation reaction mechanism, thereby achieving the purpose of purifying sewage.

[0004] Catalysts usually contain precious metals and rare metals, which can be reused after recovery to reduce waste of resources. Existing catalysts usually use sieve plates for solid-liquid separation to filter out most of the pollutants and unreacted raw materials, and then collect them.

[0005] During the long-term screening process of the catalyst by the sieve plate, the catalyst will adhere to the surface of the sieve plate, thereby clogging the through holes on the sieve plate and affecting the subsequent filtering effect. Therefore, the filter plate needs to be replaced after a period of use. When it is necessary to recover the catalyst in a large amount of wastewater, it is time-consuming and labor-intensive, and the recovery efficiency is reduced. Therefore, a catalyst recovery device for coal chemical wastewater treatment is proposed. Utility Model Content

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0037] See also Figure 1-4 As an embodiment of the utility model, a coal chemical wastewater treatment catalyst recovery device comprises a water tank 1 and a tank cover 3 arranged on the water tank 1, and a filtering structure and a scraping structure are arranged inside the water tank 1;

[0038] The filter structure intercepts the catalyst in the wastewater when filtering the wastewater;

[0039] The scraping structure is used to scrape the catalyst filtered on the filtering structure to one place for collection;

[0040] The box cover 3 is also fixedly connected with a water inlet pipe 4, and a power structure is arranged on the water inlet pipe 4, and the power structure is connected with the scraping structure;

[0041] The power structure is used to provide power to the scraping structure during scraping.

[0042] When wastewater enters the upper part of the water tank 1, it is filtered by the filter structure and then enters the lower part of the water tank 1, while the catalyst is retained on the filter structure, and the power structure drives the scraping structure to scrape the catalyst on the filter structure.

[0043] The design of the power structure can drive the scraping structure to scrape the catalyst on the filtering structure, without the need to install additional power equipment to drive it, thus reducing the production cost. The scraping of the scraping structure can effectively clean the filtering structure, thus preventing the surface of the filtering structure from being covered and blocked by the catalyst due to long-term filtration, so that it can continuously filter and treat the wastewater, without the need to frequently replace the filtering structure, and is more time-saving and labor-saving to use.

[0044] like Figure 2 As shown, the power structure includes a water wheel 6 rotatably arranged in the water inlet pipe 4, a shaft 7 is fixedly connected to the middle of the water wheel 6, and one end of the shaft 7 is fixedly connected to a first pulley 8, and the first pulley 8 cooperates with the scraping structure;

[0045] A mounting frame 5 is fixedly connected to the side wall of the water inlet pipe 4, a water wheel 6 is rotatably connected to the inside of the mounting frame 5, and the mounting frame 5 is connected to the water inlet pipe 4;

[0046] The blades of the water wheel 6 are located inside the water inlet pipe 4, and the blades of the water wheel 6 are arc-shaped structures.

[0047] Wastewater flows into the water tank 1 through the water inlet pipe 4. During the flow of wastewater, a downward force is applied to the blades of the water wheel 6, thereby driving the water wheel 6 to rotate. After the water wheel rotates, the shaft 7 and the first pulley 8 are driven to rotate synchronously, thereby providing scraping power to the scraping structure.

[0048] By designing the blades of the water wheel 6 to be arc-shaped so that it can receive more water, the gravity of the water is greater, thereby exerting greater pressure on the blades, the water wheel 6 has more power to rotate, and the force of the water flow entering and falling is effectively utilized through the rotation of the water wheel 6. There is no need to add an additional power structure, which reduces production costs, saves energy and is more environmentally friendly.

[0049] like Figure 3 As shown, the filtering structure includes a sieve plate 11 fixedly connected to the inside of the water tank 1, and a collecting frame 12 is provided on one side of the sieve plate 11;

[0050] The sieve plate 11 is installed obliquely inside the water tank 1, and the collecting frame 12 is arranged at a higher end of the sieve plate 11;

[0051] A baffle plate which is inclined upward is fixedly connected to the lower end of the sieve plate 11 .

[0052] In summary, the sieve plate 11 and the side wall of the water tank 1 are installed with a slat, and the collecting frame 12 is placed on the slat, and the scraping structure is installed to cooperate with the sieve plate 11.

[0053] After the wastewater passes through the sieve plate 11, the water flows into the water tank 1 through the through holes on the sieve plate 11, and the catalyst remains on the sieve plate 11. During the flow of the wastewater, the wastewater that has not been filtered in time flows along the sieve plate 11 to the baffle, and then flows back to the connection between the sieve plate and the baffle through the structure of the baffle for filtration, while the catalyst is retained on the sieve plate 11. Subsequently, the catalyst on the sieve plate 11 will be scraped by the scraping structure into the interior of the collection frame 12 for collection, and the collection frame 12 also has a drainage function.

[0054] Setting the collecting frame 12 at a higher position of the sieve plate 11 can prevent water from directly flowing into the collecting frame 12, which would cause excessive water inside the collecting frame 12 and cause the catalyst inside to overflow. The collecting frame 12 can be freely taken out from the inside of the water tank 1, which makes collecting the catalyst simpler and more convenient. The design of the baffle limits the filtering space for wastewater and moves the corners of the sieve plate 11 toward the middle, thereby preventing the scraping structure from being unable to effectively scrape the corners of the sieve plate 11, thereby ensuring the collection effect of the catalyst.

[0055] like Figure 3 As shown, the scraping structure includes two connecting rods 13 rotatably arranged inside the water tank 1, two third belt pulleys 14 are fixedly sleeved on each connecting rod 13, and a second belt 15 is stretched between the two third belt pulleys 14, and a scraper 16 is fixedly connected between the two second belts 15;

[0056] The second belt 15 is tensioned on the third belt pulleys 14 of the two connecting rods 13 .

[0057] The scraper 16 and the sieve plate 11 cooperate with each other. The rotation of the third pulley 14 can drive the connecting rod 13 to rotate, and then drive another connecting rod 13 to rotate through the connection of the second belt 15. At the same time, the rotation of the second belt 15 will drive the scraper 16 to rotate to scrape the catalyst on the sieve plate 11.

[0058] By installing the scraper 16 on the second belt 15, the scraper 16 can be collected reciprocatingly on the catalyst on the sieve plate 11. The collection is simple and convenient. After collecting once, the scraper 16 will be lifted upward with the transmission of the second belt 15, and will not affect the subsequent sewage filtration. Then, when the scraper 16 rotates to the baffle, it will scrape the baffle first, and then scrape the connection between the sieve plate 11 and the baffle. Compared with the back and forth scraping method, it can avoid scraping off the catalyst originally scraped up during the reverse movement, and the collection effect is better.

[0059] like Figure 2-3 As shown, one end of one of the connecting rods 13 and one end of the shaft rod 7 are fixedly connected to a second pulley 10, and the same first belt 9 is tensioned between the two second pulleys 10;

[0060] A protection frame is fixedly connected to the side wall of the water tank 1, and the two second pulleys 10 are both located in the protection frame.

[0061] The rotation of the shaft 7 drives the second belt pulley 10 to rotate, and the second belt pulley 10 drives the connecting rod 13 to rotate through the first belt 9, thereby transmitting the power.

[0062] The linkage design eliminates the need for an additional power device, reducing production costs, and the overall structure is simple and easy to maintain. At the same time, the protective frame can protect the two second pulleys 10 and the first belt 9 tensioned thereon, preventing them from being damaged by direct external forces such as bumps from the outside.

[0063] like Figure 4 As shown, a bending plate 17 is fixedly connected to the side wall of the scraper 16, and a drainage port 18 is opened on the scraper 16;

[0064] The drain port 18 is provided on the bent plate 17;

[0065] The bent plate 17 has an obtuse angle structure.

[0066] In summary, when the scraper 16 scrapes upward the catalyst remaining on the sieve plate 11, the catalyst will accumulate and enter under the bending plate 17, and the wastewater that continues to be transported will have a higher water level due to the obstruction of the scraper 14, and then the wastewater with a higher water level will overflow the bending plate 17 and be discharged from the drain port 18.

[0067] The bent plate 17 with an obtuse angle structure will block the catalyst on one side of the scraper 16, and the bend can further block the catalyst to prevent the catalyst from being discharged from the drain port along with the water flow, thereby ensuring the collection effect of the catalyst. The designed drain port 18 provides space for the water flow to flow when scraping the catalyst, thereby avoiding blocking the water flow and affecting the filtering effect of the wastewater.

[0068] like Figure 1 As shown, a drain pipe 2 is also fixedly connected to the side wall of the water tank 1;

[0069] The drain pipe 2 is fixedly connected to the lower side of the water tank 1;

[0070] The drain pipe 2 is also fixedly connected with a docking plate.

[0071] The drainage pipe can be docked with the drainage pipe 2 via a docking plate, so that the water inside the water tank 1 is discharged through the drainage pipe 2.

[0072] By arranging the drain pipe 2 below one side of the water tank 1, the water inside the water tank 1 can be directly discharged through the drain pipe 2 by its own pressure, without the need for additional pumping equipment, thus saving production costs.

[0073] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
