Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to an activated coke adsorption tank. Background Technology

[0002] Activated coke is a porous carbonaceous material produced from coke granules and coke granules. Its structure and properties are similar to those of coal-based granular activated carbon. Compared with activated carbon, it retains the advantages of activated coke: good adsorption performance, stable chemical properties, regeneration capability, and reusability.

[0003] Activated coke has a large number of pores on its surface, giving it a wide range of applications in wastewater treatment. When activated coke is used as an adsorbent in the deep treatment of raw water, it is usually introduced into the tower from the top through a coke discharge pipe, so that the tower is filled with activated coke. Wastewater enters the tower from the bottom, and the purified water flows out from the top. This increases the contact area between the activated coke and the water, thereby improving the purification effect.

[0004] When activated coke is introduced into the tower from the top, if it is introduced from the middle of the top, the activated coke in the tower may be arranged in a conical shape, resulting in poor flatness of the upper surface of the activated coke. In this case, purification by the flow of water alone will take longer, thus affecting the treatment efficiency of wastewater. Furthermore, the increased cost during the subsequent removal of activated coke necessitates further improvement. Summary of the Invention

[0005] In order to improve the uniformity of activated coke distribution within the tank and reduce the possibility of increased costs due to the discharge of underutilized activated coke, this application provides an activated coke adsorption tank.

[0006] This application provides an activated coke adsorption tank, which adopts the following technical solution:

[0007] An activated coke adsorption tank includes a tank body, a coke inlet pipe disposed at the top of the tank body, a coke outlet pipe disposed at the bottom of the tank body, a water inlet pipe disposed at the lower end of the tank body, and a water outlet pipe disposed at the upper end of the tank body. The coke inlet pipe is used to transport activated coke into the tank body. The height of the outlet of the coke inlet pipe is lower than the height of the water outlet pipe. The tank body is provided with a leveling assembly for leveling the activated coke input by the coke inlet pipe. The leveling assembly includes a scraper plate disposed at the lower end of the coke inlet pipe and a drive component for driving the scraper plate to rotate around the axis of the tank body.

[0008] By adopting the above technical solution, when activated coke is fed into the tank through the coke inlet pipe, the drive unit is activated to rotate the scraper plate, which scrapes the activated coke fed into the tank through the coke inlet pipe to improve the flatness of the upper surface of the activated coke in the tank, reducing the impact on water purification effect caused by poor flatness of the surface of the laid activated coke. It should be noted that in subsequent use, as the wastewater moves from bottom to top, after a period of time, the activated coke in the lower layer has a higher adsorption rate for impurities in the wastewater, while the activated coke in the upper layer can still be used and needs to be replaced. At this time, the activated coke in the lower layer can be discharged through the coke discharge pipe while activated coke is fed into the upper layer through the coke inlet pipe. At this time, the drive unit is activated again to rotate the scraper plate to continue to scrape the upper surface of the activated coke, making full use of the adsorption capacity of the material, improving the efficiency of water treatment, and saving costs.

[0009] Preferably, the coke inlet pipe is located close to the side wall of the tank body, and the water outlet pipe is located on the side wall of the tank body away from the coke inlet pipe; the leveling assembly also includes an mounting rod for mounting the scraper plate, and several scraper plates are spaced apart along the length direction of the mounting rod, with the length direction of the scraper plate inclined to the length direction of the mounting rod.

[0010] By adopting the above technical solution, the coke inlet pipe is set close to the side wall of the tank body, and the water outlet pipe is set on the side wall of the tank body away from the coke inlet pipe. This makes the distance between the coke inlet pipe and the water outlet pipe longer, which increases the difficulty for some dust after coke enters the coke inlet pipe to flow out with the water from the water outlet pipe, thereby reducing the content of activated coke in the discharged water.

[0011] Because the coke inlet tube is located on the side wall, by tilting the length of the scraper plate to the length of the mounting rod, during the rotation of the scraper plate, some activated coke can fill the gaps in height for leveling, while some activated coke flows from one end of the scraper plate to the other end to be pushed to the area leveled by the next scraper plate. With several scraper plates, the leveling speed of the activated coke is accelerated, and the time spent leveling the activated coke is reduced.

[0012] Preferably, the tank is provided with an adsorption component for adsorbing the dust generated when the activated coke is transported through the coke inlet pipe, and the adsorption component is disposed above the scraper plate.

[0013] By adopting the above technical solution, when the activated coke is transported into the tank through the coke inlet pipe, a certain amount of dust will be generated. If the machine is not stopped, some water will be discharged through the discharge port during coke discharge and coke feeding, and the water level may be lower than the discharge port of the coke inlet pipe. During coke feeding and during the process of scraping the activated coke, some dust will fly to the water outlet pipe. Therefore, an adsorption component is installed to adsorb the dust generated when the activated coke is transported through the coke inlet pipe.

[0014] Preferably, the adsorption assembly includes a spray pipe, a nozzle disposed on the spray pipe, and a first control element for controlling the opening and closing of the nozzle and thus controlling the opening and closing of the spray pipe. Several nozzles are disposed at intervals along the length of the water inlet pipe, and one end of the spray pipe is disposed close to the coke inlet pipe.

[0015] By adopting the above technical solution, when feeding into the coke inlet pipe, the first control component presses the nozzle to spray water through the nozzle, causing the flying dust to absorb water, become heavier, and fall off, thus reducing the possibility of dust flying to the water outlet pipe. Furthermore, the multiple nozzles not only adsorb the dust at the coke inlet pipe but also adsorb the dust raised by the scraper plate when scraping the surface of the activated coke, thereby reducing the possibility of dust flying to the water outlet pipe.

[0016] Preferably, the nozzle is a press-type nozzle, and the first control component includes a press rod for pressing the press end of the nozzle, a counterweight block disposed on the press rod to press the nozzle, and a first float plate disposed on the mounting rod, the first float plate being located above the scraper plate.

[0017] By adopting the above technical solution, without shutting down the system (i.e., while the water inlet pipe continues to supply water), some water will be discharged along with the coke discharge pipe during coke discharge. As the water level drops, the weight of the counterweight itself will drive the pressing rod to press the pressing end of the nozzle, causing the nozzle to open and water to be sprayed into it for adsorption of dust. After the coke discharge in the tank is completed and the upper surface of the activated coke is leveled, as wastewater continues to be fed into the tank, the water level in the tank rises to the height of the first float plate. The first float plate floats up due to the buoyancy of the water, causing the pressing rod to rise as well. As the water level rises, the pressing rod moves away from the pressing end of the nozzle, thus reducing the amount of water that can be sprayed by the nozzle. It should be noted that since the first float plate is located above the scraper plate, and the scraper plate has stopped working, most of the dust that could be thrown up has been adsorbed by the sprayed water, reducing the possibility of the thrown dust reaching the water outlet pipe.

[0018] Preferably, the inner wall of the tank is provided with a triangular weir plate, the length direction of the triangular weir plate is parallel to the length direction of the water outlet pipe and is connected to the water outlet pipe, and the height of the triangular weir plate is higher than the height of the scraper plate.

[0019] By adopting the above technical solution, due to the fluidity of water, activated coke may flow to the outlet pipe. At this time, by setting up a triangular weir plate, only water above the triangular weir plate can flow from the outlet pipe, further reducing the activated coke content in the discharged water.

[0020] Preferably, the tank body is rotatably connected to a cover plate for covering the water inlet ends on opposite sides of the triangular weir plate, and a second control component for controlling the flipping of the cover plate.

[0021] By adopting the above technical solution, when the activated coke is transported into the tank through the coke inlet pipe, some dust may be generated and fly to the triangular weir plate. During the process of coke feeding and scraping the activated coke, the second control component is activated so that the cover plate closes the water inlet ends on both sides of the triangular weir plate, thereby reducing the possibility of dust flying to the triangular weir plate and thus reducing the activated coke content in the discharged water.

[0022] Preferably, the second control element includes a second float plate disposed at the lower end of the cover plate, the second float plate being disposed on the side wall of the cover plate away from the triangular weir plate.

[0023] By adopting the above technical solution, and by setting a second float plate, as the water level rises to the height of the second float plate, the second float plate comes into contact with the water. As the water level rises, it drives the cover plate to rotate along the position where it is connected to the top wall of the tank, so that the purified water flows from the inlet end of the triangular weir plate to the outlet pipe for discharge.

[0024] Preferably, the cover plate has a guide groove on its side wall near the triangular weir plate, the guide groove extending to the lower end face of the cover plate, and the second control component is a lifting plate disposed on the pressing rod, the upper end of the lifting plate being slidably inserted into the guide groove.

[0025] By adopting the above technical solution, a lifting plate that is slidably inserted into the guide groove is provided. As the first float rises, it drives the lifting plate to rise, thereby applying an upward pushing force to the cover plate, so that the cover plate rotates along the top wall of the tank at the rotational connection position, thereby achieving control of the cover plate.

[0026] Preferably, the length direction of the spray pipe is inclined to the length direction of the triangular weir plate, and two lifting plates are provided, each located below one of the two cover plates.

[0027] By adopting the above technical solution, since there are two cover plates, the length direction of the spray pipe is inclined to the length direction of the triangular weir plate so that two lifting plates can be arranged to lift and flip the two cover plates respectively.

[0028] In summary, this application has the following beneficial effects:

[0029] 1. By installing a leveling component inside the tank, the activated coke fed into the tank through the coke inlet pipe is leveled, thereby improving the flatness of the upper surface of the activated coke when it is located inside the tank and reducing the impact on water purification effect caused by poor flatness of the upper surface of the laid activated coke.

[0030] 2. Since a certain amount of dust is generated when the activated coke is transported into the tank through the coke inlet pipe, if it flows to the water outlet pipe, the activated coke content in the discharged water may be high. Therefore, an adsorption component is installed to adsorb the dust generated when the activated coke is transported through the coke inlet pipe.

[0031] 3. Similarly, when activated coke is transported into the tank through the coke inlet pipe, some dust may be generated and fly to the triangular weir plate. By setting a second control component, the cover plate can close the water inlet ends on both sides of the triangular weir plate to reduce the possibility of dust flying to the triangular weir plate, thereby reducing the activated coke content in the discharged water.

[0042] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail below.

[0043] This application discloses an activated coke adsorption tank.

[0044] Example 1:

[0045] An activated coke adsorption tank, as described above Figure 1 , Figure 2 The system includes a tank body 1, a coke inlet pipe 11, a coke outlet pipe 12, a water inlet pipe 13, and a water outlet pipe 14. The tank body 1 is used for wastewater treatment. The upper end of the tank body 1 is cylindrical, and the bottom wall is inverted conical. In this embodiment, the cone angle of the bottom wall of the tank body 1 is 90 degrees. The top wall of the tank body 1 is open, and a tank cover 15 is provided on the top of the tank body 1 for opening and closing the opening. It should be noted that the tank cover 15 is detachably connected to the tank body 1 via latches 16. Several latches 16 are spaced apart around the axis of the tank cover 15, and the number is fixed according to requirements. Since latches 16 are a commonly used technology in the prior art, they will not be described in detail here. Support legs 17 are fixedly connected to the bottom wall of the tank body 1. Several support legs 17 are spaced apart around the axis of the tank body 1 to support the tank body 1.

[0046] The activated carbon inlet pipe 11 is used to transport new activated carbon into the tank 1, i.e., the carbon inlet operation. The lower end of the inlet pipe 11 is fixedly inserted through the tank cover 15 and extends into the tank 1. In this embodiment, the inlet pipe 11 is located close to the side wall of the tank 1. The activated carbon discharge pipe 12 is used to discharge the used and saturated activated carbon out of the tank 1, i.e., the carbon discharge operation. The discharge pipe 12 is located in the middle of the bottom wall of the tank 1, and the upper end of the discharge pipe 12 is fixedly inserted through the bottom wall of the tank 1. With the inlet pipe 11 at the top of the tank 1 and the discharge pipe 12 at the bottom of the tank 1, the activated carbon below can be discharged through the discharge pipe 12. This process does not require stopping the machine to replace the saturated activated carbon, improving the utilization rate of the equipment. At the same time, the wastewater and activated carbon convect, making full use of the adsorption capacity of the activated carbon, improving the efficiency of water treatment, and saving costs.

[0047] The inlet pipe 13 is used to transport sewage into the tank 1. The inlet pipe 13 is located at the lower end of the tank 1, specifically fixedly inserted through the side wall of the tank 1 and extending into the tank 1. A water distributor 131 is fixedly connected to the drain end of the inlet pipe 13. In this embodiment, the water distributor 131 is a multi-arm water distributor, specifically an eight-arm water distributor, to improve the uniformity of the discharged water distribution. The outlet of the water distributor 131 can be located on the upper surface or the lower surface of the water distributor 131, depending on the requirements. In this embodiment, it is specifically located on the lower surface of the water distributor 131. Because there is a certain distance between the water distributor 131 and the bottom wall of the tank 1, the possibility of a decrease in the utilization rate of activated carbon can be reduced.

[0048] To improve the stability of the water distributor 131, a diagonal brace 132 is fixedly connected to the middle of the water distributor 131, and the end of the diagonal brace 132 away from the water distributor 131 is fixedly connected to the bottom wall of the tank body 1.

[0049] The water outlet pipe 14 is used to discharge the purified water into the tank 1. The water outlet pipe 14 is located at the upper end of the tank 1 and is fixedly installed through the side wall of the tank 1 and close to the tank cover 15. It should be noted that the water outlet pipe 14 is located on the side wall of the tank 1 away from the coke inlet pipe 11, so that the distance between the coke inlet pipe 11 and the water outlet pipe 14 is longer. This increases the difficulty for some dust after entering the coke through the coke inlet pipe 11 to flow out with the water from the water outlet pipe 14, thereby reducing the content of activated coke in the discharged water.

[0050] It should be noted that in this embodiment, the height of the discharge port of the coke inlet pipe 11 is lower than the height of the water outlet pipe 14 to reduce the possibility of dust flowing to the water outlet pipe 14 during coke feeding. In this embodiment, valves (not shown in the figure) are provided on the coke inlet pipe 11, coke discharge pipe 12, water inlet pipe 13 and water outlet pipe 14. Since this is the prior art, it will not be described in detail here.

[0051] Reference Figure 2 , Figure 3 Furthermore, due to the fluidity of water, activated coke may flow to the outlet pipe 14. In order to reduce the content of activated coke in the discharged water, in this embodiment, a triangular weir plate 2 is provided on the inner wall of the tank 1, specifically a trough. The length direction of the triangular weir plate 2 is parallel to the length direction of the outlet pipe 14 and is connected to the outlet pipe 14.

[0052] Furthermore, during the coking process, the new activated coke falls into the tank 1 with poor flatness. To reduce the impact on water purification due to the poor flatness of the surface of the activated coke, a leveling component 3 is installed in the tank 1 to level the activated coke fed into the coking pipe 11.

[0053] Specifically, the leveling assembly 3 includes a scraper plate 31 disposed at the lower end of the coke inlet pipe 11, an mounting rod 32 for mounting the scraper plate 31, and a driving component 33 for driving the scraper plate 31 to rotate around the axis of the tank body 1. The scraper plates 31 are arranged at intervals along the length direction of the mounting rod 32. In this embodiment, the length direction of the scraper plate 31 is inclined to the length direction of the mounting rod 32. It should be noted that the scraper plate 31 can be arranged in a straight plate or an arc shape. The specific shape is set according to the requirements. In this embodiment, the scraper plate 31 is specifically arranged in a straight plate shape, and the upper end surface of the scraper plate 31 is fixedly connected to the lower end surface of the mounting rod 32.

[0054] Reference Figure 1 , Figure 2 The driving component 33 includes a drive motor 331 fixedly connected to the outer top wall of the can lid 15 and a rotating rod 332 coaxially connected to the output shaft of the drive motor 331. The output shaft of the drive motor 331 is fixedly inserted through the can lid 15, and the lower end of the rotating rod 332 is fixedly connected to the middle of the mounting rod 32. The drive motor 331 is started to drive the rotating rod 332 to rotate, thereby driving the scraper plate 31 installed on the mounting rod 32 to scrape the newly entered activated coke. It should be noted that the height of the triangular weir plate 2 is higher than the height of the scraper plate 31, and to reduce the rotation of the rotating rod 332 by the triangular weir plate 2, the rotating rod 332 rotates through the triangular weir plate 2.

[0055] It should be noted that by tilting the length direction of the scraper plate 31 to the length direction of the mounting rod 32, during the rotation of the scraper plate 31, some of the activated coke can fill the gaps in the height for leveling, while some of the activated coke flows with one end of the scraper plate 31 to the other end, pushing it to the area leveled by the next scraper plate 31 for leveling. With several scraper plates 31, the leveling speed of the activated coke is accelerated, and the time spent leveling the activated coke is reduced.

[0056] Reference Figure 3 , Figure 4 Furthermore, in order to reduce the possibility of dust flying up during coke feeding or scraping the activated coke falling onto the outlet pipe 14, the tank body 1 is provided with an adsorption component 4 for adsorbing the dust generated when the activated coke is transported by the coke feeding pipe 11. The adsorption component 4 is located above the scraping plate 31. Specifically, the adsorption component 4 includes a spray pipe 41, a nozzle 42 fixedly inserted through the side wall of the spray pipe 41, and a first control element 43 for controlling the opening and closing of the nozzle 42 and thus controlling the opening and closing of the spray pipe 41.

[0057] Reference Figure 4 , Figure 5 In this embodiment, the length direction of the spray pipe 41 is inclined to the length direction of the triangular weir plate 2. One end of the spray pipe 41 is fixedly connected to the inner wall of the tank body 1, and the other end of the spray pipe 41 is fixedly inserted through the tank body 1. One end of the spray pipe 41 is located near the coke inlet pipe 11, and a valve is provided on the spray pipe 41. The valve is located outside the tank body 1.

[0058] In this embodiment, several nozzles 42 are spaced apart along the length of the spray pipe 41. The nozzles 42 are press-type nozzles 42 and atomizing nozzles. The nozzles 42 are fixedly installed through the side wall of the water inlet pipe 13, and the press end on the nozzle 42 is located on the upper end face of the nozzle 42.

[0059] Reference Figure 4 , Figure 7 The first control component 43 specifically includes a pressing rod 431, a connecting plate 432, a lifting rod 433, a first float plate 434, and a counterweight 435. Several pressing rods 431 are provided, specifically equal to the number of nozzles 42. The lower end face of several pressing rods 431 is used to press the pressing end on the nozzle 42. The upper end of several pressing rods 431 is fixedly connected to the lower surface of the connecting plate 432. In this embodiment, sliders 5 are fixedly protruding from the opposite two end faces of the connecting plate 432. The inner side wall of the tank 1 is provided with a sliding groove 18 for the sliders 5 to slide and connect, so as to limit the lifting and lowering of the connecting plate 432, thereby making the pressing rods 431 and the pressing ends on the nozzles 42 correspondingly set.

[0060] The lifting rod 433 is fixedly connected to the lower surface of the connecting plate 432 away from the pressing rod 431. The first float plate 434 is disposed at the lower end of the lifting rod 433. The lifting rod 433 is fixedly inserted through the first float plate 434. It should be noted that the first float plate 434 is located above the scraper plate 31, and its height is higher than the height of the coke inlet pipe 11 at the outlet. The counterweight block 435 is disposed on the lower end surface of the first float plate 434 and is fixedly connected to the lower end surface of the lifting rod 433.

[0061] Without shutting down the machine, that is, while the water inlet pipe 13 continues to supply water, during the coke feeding and coke discharge processes, some water will be discharged through the coke discharge pipe 12. When the water level drops, the weight of the counterweight block 435 will cause the lifting rod 433, the connecting plate 432, and the pressing rod 431 to descend, so that the pressing rod 431 presses the pressing end of the nozzle 42, opening the nozzle 42, and water is input into the nozzle 42 for spraying to adsorb the dust. After the coke discharge in tank 1 is completed and the upper surface of the activated coke is leveled, as wastewater continues to be fed into tank 1, the water level in tank 1 rises to the height of the first float 434. The first float 434 floats up due to the buoyancy of the water, which in turn causes the pressing rod 431 to rise as well. As the water level rises, the pressing rod 431 moves away from the pressing end of the nozzle 42, thereby reducing the amount of water that the nozzle 42 can spray, thus controlling the amount of water that the nozzle 42 can spray.

[0062] The implementation principle of an activated coke adsorption tank according to an embodiment of this application is as follows: After the activated coke filling the tank 1 has treated the sewage for a period of time, since the sewage flows from bottom to top, the activated coke in the lower layer has a higher adsorption rate for impurities in the sewage. Therefore, it is necessary to discharge the saturated activated coke into the tank 1. Specifically, the valve set on the coke discharge pipe 12 is opened to discharge the activated coke into the tank 1. At the same time, the coke inlet pipe 11 above is opened to input new activated coke into the tank 1.

[0063] When coke is fed in, the drive motor 331 is started so that the scraper plate 31 scrapes the new activated coke. Since dust will be generated during the coke feeding and scraping process, in order to reduce the dust flying to the water outlet pipe 14, the nozzle 42 needs to be opened during the coke feeding and scraping process.

[0064] When the system is running continuously, some of the water in tank 1 will be discharged through the coke discharge pipe 12. As the water level drops, the second float 71 will also drop along with the water level to cover the side wall of the triangular weir plate 2, thereby reducing dust from being blown to the water outlet pipe 14. As the water level continues to drop, the weight of the counterweight block 435 will cause the lifting rod 433, connecting plate 432, and pressing rod 431 to descend, so that the pressing rod 431 presses the pressing end of the nozzle 42, opening the nozzle 42 and allowing water to be sprayed into the nozzle 42 for adsorption of dust.

[0065] After the coke discharge in tank 1 is completed and the upper surface of the activated coke is also scraped flat, as wastewater continues to be input into tank 1, the water level in tank 1 rises to the height of the first float plate 434. The first float plate 434 floats up due to the buoyancy of the water, thereby closing the nozzle 42. When the water level rises to contact the second float plate 71, it drives the cover plate 6 to move away from the triangular weir plate 2, so that the purified wastewater can flow through the triangular weir plate 2 to the outlet pipe 14 and flow out of tank 1.

[0066] Example 2:

[0067] Reference Figure 8 The difference from Embodiment 1 is that, since a triangular weir plate 2 is provided, dust may fly onto the triangular weir plate 2 and accumulate during coking and leveling operations. Therefore, in this embodiment, two cover plates 6 are rotatably connected inside the tank body 1, which are respectively used to cover the water inlet ends on opposite sides of the triangular weir plate 2, and a second control component 7 for controlling the flipping of the cover plates 6.

[0068] In this embodiment, when the sewage level in the tank 1 is lower than that of the cover plate 6, the cover plate 6 is affected by gravity and abuts against the opposite side walls of the triangular weir plate 2. The second control component 7 is a second float plate 71, which is fixedly connected to the side wall of the cover plate 6 away from the triangular weir plate 2. As the water level rises to the height of the second float plate 71, the second float plate 71 comes into contact with the water. As the water level rises, it drives the cover plate 6 to rotate along the position where it is rotatably connected to the top wall of the tank 1, so that the purified water flows from the inlet end of the triangular weir plate 2 to the outlet pipe 14 for discharge.

[0069] Example 3:

[0070] Reference Figure 9 The difference from Embodiment 2 is that a guide groove 61 is provided on the side wall of the cover plate 6 near the triangular weir plate 2. The guide groove 61 extends to the lower end face of the cover plate 6. In this embodiment, the second control member 7 is a lifting plate 72 fixedly connected to the connecting plate 432. The upper end of the lifting plate 72 is slidably inserted into the guide groove 61. There are two lifting plates 72, which are respectively located below the two cover plates 6. It should be noted that since the lifting plate 72 is located on the connecting plate 432, in order to make the angle of the pushed cover plate 6 larger, the distance between the triangular weir plate 2 and the connecting plate 432 is larger at this time.

[0071] As the first float plate 434 rises, it drives the lifting plate 72 to rise, thereby applying an upward pushing force to the cover plate 6, so that the cover plate 6 rotates along the top wall of the tank 1 at the rotational connection position, thereby achieving control of the cover plate 6.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
