Description

Technical Field

[0001] This utility model belongs to the field of activated carbon stirring, and specifically relates to a high-efficiency stirring device for activating powdered activated carbon pyrolysis solution. Background Technology

[0002] Powdered activated carbon is a porous adsorbent material that forms a well-developed pore structure and a large specific surface area through high-temperature pyrolysis and chemical activation. It is widely used in water treatment, waste gas purification, food decolorization and other fields. Its core performance lies in the uniformity of the activation process, and pyrolysis activation is a key process step. During the pyrolysis activation process, the efficiency of the stirring device directly affects the uniformity of mixing between the activator and the raw materials and the reaction efficiency. Conventional paddle designs are prone to laminar flow in viscous pyrolysis liquids, resulting in significant differences in mixing intensity between the central and peripheral areas and uneven distribution of the activator. Moreover, the use of conventional stirring paddles alone can easily cause material to settle at the bottom of the tank, resulting in incomplete activation of the activated carbon and failure to integrate agitation of the bottom wall of the tank to reduce dead zones.

[0003] Therefore, we hope to design a high-efficiency stirring device for activating powdered activated carbon pyrolysis solution to solve this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-efficiency stirring device for activating powdered activated carbon pyrolysis solution, thereby solving the problems mentioned in the background technology.

The inner barrel is located inside the activation furnace, and a heat storage chamber and a solution chamber are formed between the inner barrel and the activation furnace. A heating unit is provided inside the heat storage chamber.

[0006] The inner barrel is equipped with a rotating shaft, the surface of the rotating shaft is equipped with a stirring paddle, and the outside of the stirring paddle is equipped with a scraper. A water pump is installed on the left side of the activation furnace, and the two ends of the water pump are respectively connected to the storage tank and the interior of the solution chamber.

[0007] The base frame is equipped with a material unloading platform and a hydraulic rod, and the top of the hydraulic rod is connected to a stopper plate.

[0008] In a preferred embodiment, the left and right ends of the inner barrel are welded to the inside of the activation furnace. The heating unit consists of multiple electric heating rods, which are evenly installed inside the heat storage chamber. The heating unit allows for more precise control of the temperature in each area of ​​the inner barrel, ensuring a uniform distribution of micropores and mesopores in the activated carbon.

[0009] In a preferred embodiment, a set of scrapers is connected to both the top and bottom of the stirring paddle. The two sets of scrapers are symmetrically attached to the inner walls of the upper and lower sides of the inner barrel. The scrapers can scrape the activated carbon adhering to the inner wall of the inner barrel into the stirring zone, improve the dispersion uniformity, and facilitate the full mixing of activated carbon and activation liquid.

[0010] In a preferred embodiment, the liquid storage tank is installed on the left side of the base frame, and one end of the water pump is connected to a water pumping pipe for drainage, which is connected to the inside of the liquid storage tank.

[0011] In a preferred embodiment, the other end of the water pump is connected to a drain pipe. The drain pipe penetrates the activation furnace and enters the solution chamber. The inner wall of the solution chamber extends downwards into the inner tank, forming multiple through holes. The water pump can introduce the activator into the solution chamber, and then discharge it into the inner tank through the through holes at the bottom of the solution chamber to mix the activator with the activated carbon.

[0012] In a preferred embodiment, the bottom of the activation furnace extends upward through the inner barrel to form a discharge port. The discharge port has a rectangular cross-section, and a plug plate is connected inside the discharge port to seal it.

[0013] In a preferred embodiment, an inclined unloading platform is installed below the base frame. The hydraulic rods are installed in two groups on the left and right sides of the bottom of the unloading platform.

[0014] In a preferred embodiment, the top right side of the activation furnace extends downwards into the inner tank to form a feed inlet, which is located in front of the solution chamber.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: By installing an inner barrel inside the activation furnace, the heat storage chamber and the solution chamber can be set in the gap between the activation furnace and the inner barrel, making the inner wall of the inner barrel smooth enough so that the scraper on the surface of the stirring paddle can fully fit against the inner wall of the inner barrel. When the stirring paddle drives the scraper to rotate, the scraper can stir the bottom wall of the inner barrel to reduce the stirring dead zone and avoid the deposition of activated carbon on the bottom wall of the inner barrel, thereby improving the activation efficiency of activated carbon and realizing efficient stirring of the material in the inner barrel. In addition, the water pump can introduce the activator into the solution chamber and then discharge it into the inner barrel. When the stirring paddle rotates, the activator and activated carbon can be mixed. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1 to 4This utility model provides a technical solution: a high-efficiency stirring device for activating powdered activated carbon pyrolysis solution, comprising: a base frame 100, an activation furnace 200, an inner barrel 210, and a rotating motor 300. The activation furnace 200 and the inner barrel 210 are installed on the top of the base frame 100, and the rotating motor 300 is installed on the right side of the activation furnace 200. The inner barrel 210 is located inside the activation furnace 200, and a heat storage chamber 220 and a solution chamber 230 are formed between the inner barrel 210 and the activation furnace 200. A heating unit 250 is provided inside the heat storage chamber 220.

[0028] The inner barrel 210 is equipped with a rotating shaft 310, the surface of the rotating shaft 310 is equipped with a stirring paddle 320, and the outside of the stirring paddle 320 is equipped with a scraper 330. The activation furnace 200 is equipped with a water pump 410 on the left side, and the two ends of the water pump 410 are connected to the liquid storage tank 400 and the inside of the solution chamber 230, respectively.

[0029] The base frame 100 is provided with a feeding platform 600 and a hydraulic rod 500 below it, and the top of the hydraulic rod 500 is connected to a plug plate 510.

[0030] The inner barrel 210 is welded to the inside of the activation furnace 200 at both ends. The heating unit 250 consists of multiple electric heating rods, which are evenly installed inside the heat storage chamber 220. The heating unit 250 can more accurately control the temperature of each area in the inner barrel 210 through the evenly distributed multiple electric heating rods, which can effectively eliminate temperature differences and ensure that the micropores and mesopores of the activated carbon are evenly distributed.

[0031] A set of scrapers 330 is connected to both the top and bottom of the stirring paddle 320. The two sets of scrapers 330 are symmetrically attached to the inner walls of the upper and lower sides of the inner barrel 210. The scrapers 330 can scrape the activated carbon adhering to the inner wall of the inner barrel 210 into the stirring zone, improve the dispersion uniformity, facilitate the full mixing of activated carbon and activation liquid, achieve efficient stirring of activated carbon, and when the activated carbon is discharged, the scraping action makes it easy to remove the residues attached to the barrel wall of the inner barrel 210.

[0032] Please see Figures 1 to 3 As the first embodiment of this utility model: Before actual use, powdered activated carbon is first fed into the inner barrel 210 through the inlet of the activation furnace 200, and at the same time, the activator is added into the storage tank 400. During actual use, the heating unit 250 is powered first. The heating unit 250 raises the temperature between the activation furnace 200 and the inner barrel 210 by turning on the electric heating rod, and then pours the heat into the inner barrel 210 in the form of heat conduction to heat the powdered activated carbon, which also facilitates meeting the temperature requirements of the activator.

[0033] Simultaneously, the rotating motor 300 is turned on, and the rotating motor 300 drives the stirring paddle 320 to rotate via the rotating shaft 310. During the rotation of the stirring paddle 320, the powdered activated carbon is stirred and circulated to move the activated carbon in the outer high-temperature zone to the central low-temperature zone, so that the activator solution can evenly coat the surface of the powdered activated carbon. At the same time, the rotation of the stirring paddle 320 drives the scraper 330 to rotate against the inner wall of the inner barrel 210, which can stir the bottom wall of the inner barrel 210 to reduce the stirring dead zone and avoid the deposition of activated carbon on the bottom wall of the inner barrel 210, thereby improving the activation efficiency of the activated carbon and achieving efficient stirring of the materials in the inner barrel 210.

[0034] The liquid storage tank 400 is installed on the left side of the base frame 100. One end of the water pump 410 is connected to a water pump pipe 420 for drainage, which is connected to the inside of the liquid storage tank 400.

[0035] The other end of the water pump 410 is connected to a drain pipe 430. The drain pipe 430 penetrates the activation furnace 200 and enters the solution chamber 230. The inner wall of the solution chamber 230 extends downward to the inner tank 210, forming multiple through holes. Before actual use, the activator is added to the storage tank 400. When in use, the activator can be introduced into the solution chamber 230 by the water pump 410, and then discharged into the inner tank 210 through the through holes at the bottom of the solution chamber 230. When the stirring paddle 320 rotates, the activator and activated carbon can be mixed.

[0036] The bottom of the activation furnace 200 extends upward through the inner barrel 210 to form a discharge port 240. The discharge port 240 has a rectangular cross-section, and a plug plate 510 is connected inside the discharge port 240 to seal it.

[0037] Please see Figure 3 As a second embodiment of this utility model: In order to promote the formation of pores during the activation process of activated carbon, the water pump 410 is turned on. The water pump 410 can draw the activator through the water pipe 420 and then put it into the solution chamber 230 through the drain pipe 430. Under the action of liquid pressure, the activator enters the inner barrel 210 through the bottom hole of the solution chamber 230. When the stirring paddle 320 and the scraper 330 rotate, the activator and activated carbon can be fully mixed, avoiding the accumulation of activated carbon on the bottom wall of the inner barrel 210. Moreover, when the rotating motor 300 is not turned on, the activator can be introduced into the inner barrel 210 through the water pipe 420 to soak the powdered activated carbon, thereby satisfying the requirement of promoting the formation of new pore structures in the activated carbon during the activator reaction process.

[0038] A tilted feeding platform 600 is installed below the base frame 100. Two sets of hydraulic rods 500 are installed on the left and right sides of the bottom of the feeding platform 600. The two sets of hydraulic rods 500 penetrate the feeding platform 600 and are connected to the bottom of the stopper plate 510. By installing the stopper plate 510 on the top of the hydraulic rods 500, the hydraulic rods 500 can push the stopper plate 510 into the discharge port 240 at the bottom of the inner barrel 210, thereby sealing the inner barrel 210 and the activation furnace 200. After the stopper plate 510 moves down, the activated carbon is fed.

[0039] The top right side of the activation furnace 200 extends downwards into the inner tank 210 to form a feed inlet, which is located in front of the solution chamber 230.

[0040] Please see Figure 4 As a third embodiment of this utility model: after the activated carbon activation treatment is completed, by controlling the hydraulic rod 500 to descend, the stopper plate 510 can be moved downward, so that the stopper plate 510 is separated from the discharge port 240. At this time, the powdered activated carbon in the inner barrel 210 can fall onto the discharge platform 600 under its own gravity, realizing the discharge process. At the same time, the stirring paddle 320 and scraper 330 can be rotated by rotating the motor 300. When the scraper 330 rotates, it can remove the residues attached to the wall of the inner barrel 210, improving the discharge effect.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
