In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
The invention provides a preparation method of an activated carbon product and the activated carbon product.
Referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of a method for manufacturing an activated carbon product according to the present invention.
While a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in a different order than presented herein.
The preparation method of the activated carbon product comprises the following steps:
step S100, mixing powdered activated carbon, an adhesive and a functional filter material to obtain a first mixture;
in one embodiment, the preparation materials of the method for producing the activated carbon product of the present invention include powdered activated carbon, a binder, and a functional filter material. And mixing the prepared materials uniformly to obtain a first mixture. The powdered activated carbon is an adsorbent with adsorption performance and wide application, and is black porous solid carbon, including but not limited to coconut shell activated carbon, wood activated carbon, coal activated carbon and the like. The adhesive is a substance having viscosity, and can connect two separate materials together, in this embodiment, the powdered activated carbon and the functional filter material are uniformly and firmly bonded together, and the adhesive includes, but is not limited to, hot melt adhesive, solvent-based adhesive, solvent-free adhesive, and the like. The functional filter material is a filter material used in the production and living process, and can be a granular material for filtering inlet water in water treatment equipment, including but not limited to quartz sand, gravel, anthracite, cobblestone, manganese sand, magnetite filter material, a shell filter material, foam filter beads, porcelain sand filter material, ceramsite, garnet filter material, medical stone filter material, sponge iron filter material, activated alumina balls, zeolite filter material, volcanic rock filter material, granular activated carbon, fiber balls, fiber bundle filter material, comet type fiber filter material and the like, or a physically separated filter medium, including but not limited to filter cloth, a filter screen, a filter element, filter paper and a latest membrane.
Further, in one embodiment, powdered activated carbon having a particle size of 80 to 325 mesh, a binder having a particle size of 25 μm, and a functional filter material having a particle size of 10 to 80 mesh are mixed to obtain a first mixture.
In one embodiment, the powdered activated carbon has a particle size of 80-325 mesh, the binder has a particle size of 25 μm, and the functional filter material has a particle size of 10-80 mesh. It can be understood that the binder used in the raw material is an ultrafine powder binder, the particle size is 25 μm, therefore, because the ultrafine binder has small particle size, the interaction force between the particles is strong, and agglomeration easily occurs, so that the powder binder and the powder activated carbon are easily bonded with the functional filter material, and the mutual bonding force between the activated carbon and the binder is stronger than that between the macromolecules, so that the powder activated carbon and the functional filter material bonded by the binder are not easily peeled off by water.
Further, in one embodiment, the ratio of the powdered activated carbon, the binder and the functional filter material is as follows: 75-90% of powdered activated carbon, 8-30% of adhesive and 5-20% of functional filter material.
In one embodiment, powdered activated carbon in a mass ratio of about 75-90%, a binder in a mass ratio of about 8-30%, and a functional filter material in a mass ratio of about 5-20% are mixed to obtain a first uniformly mixed mixture, and the first uniformly mixed mixture is subsequently heated, cooled and shaped. For example, 80% powdered activated carbon, 10% binder, and 10% functional filter material may be mixed to obtain a first mixture that is uniformly mixed. The above embodiment only gives the mixture ratio of the three raw materials by way of example, and of course, other mixture ratios are also possible, and still other mixture ratios are within the mixture ratio range of the patent: 75-90% of powdered activated carbon, 8-30% of adhesive and 5-20% of functional filter material; other proportions can still achieve the aim of the invention.
Further, step S100 includes:
step S110, premixing the powdered activated carbon and the adhesive to obtain a second mixture;
and step S120, mixing the second mixture and the functional filter material to obtain the first mixture.
Wherein the second mixture is a mixture of a binder and powdered activated carbon which are polymerized together by physical means, no chemical change occurs during the mixing process, only the mixing between different substances occurs, and the binder is uniformly bonded with the powdered activated carbon. The first mixture is a mixture of the second mixture and the functional filter material which are polymerized together by physical means, the chemical change does not occur in the mixing process, only the mixing between different substances occurs, and the second mixture comprises the binder and the powdered activated carbon, so that the first mixture comprises the activated carbon, the binder and the functional filter material, and the activated carbon, the binder and the functional filter material are uniformly mixed together.
In one embodiment, after the raw materials are prepared, the production of the activated carbon product is started, and the powdered activated carbon and the binder are first put into a mixer according to a proper ratio, and the powdered activated carbon and the binder in the raw materials are premixed so that the powdered activated carbon and the binder are uniformly mixed. And premixing for a period of time to obtain a second mixture with uniformly distributed powdered activated carbon and adhesive, mixing the second mixture with uniformly distributed powdered activated carbon and adhesive with the functional filter material again, and mixing to obtain a first mixture with uniformly distributed powdered activated carbon, adhesive and functional filter material. That is, the powdered activated carbon, the binder and the functional filter material are mixed first, the powdered activated carbon and the binder are mixed first, and then the uniformly mixed powdered activated carbon and the binder are mixed with the functional filter material. When the functional activated carbon product needs to be produced, other filter materials need to be added, once the specific gravity of the filter material is much higher than that of the activated carbon and the adhesive, the density of the functional filter material is higher than that of the activated carbon and the adhesive, therefore, the powdered activated carbon and the adhesive are premixed, the powdered activated carbon and the adhesive are uniformly mixed, then the uniformly mixed second mixture and the functional filter material are mixed, and the powdered activated carbon and the adhesive with relatively low density can be uniformly mixed with the functional filter material with relatively high density.
Further, in an embodiment, in step S110, the step of premixing the powdered activated carbon and the binder to obtain a second mixture includes:
and S111, stirring the mixture of the powdered activated carbon and the adhesive through a high-speed stirrer within a first preset time to obtain a second mixture, wherein the range of the first preset time is 20-30 minutes.
In one embodiment, after the raw materials are prepared, the preparation of the activated carbon product is started, and the powdered activated carbon and the binder are put into a high-speed stirrer according to a proper proportion, and the powdered activated carbon and the binder in the raw materials are premixed for 20 to 30 minutes, so that the powdered activated carbon and the binder are uniformly mixed. Because the particle size of the superfine adhesive is small, the interaction force between particles is strong, the superfine powder adhesive is easy to agglomerate, if a common stirrer cannot uniformly distribute the agglomerated adhesive, the product performance is seriously influenced, on one hand, a high-speed stirrer can provide larger shearing force to counteract the attractive force between the adhesive particles, on the other hand, the activated carbon obtains larger kinetic energy to impact and contact the adhesive, the uniform mixing of the activated carbon and the adhesive is facilitated, and the second mixture and the functional filter material which can uniformly mix the powdered activated carbon and the adhesive in the next step are further facilitated to be mixed.
Further, in an embodiment, in step S120, the step of mixing the second mixture and the functional filter material to obtain the first mixture includes:
and S121, stirring the second mixture and the functional filter material through a three-dimensional stirrer within a second preset time to obtain the first mixture, wherein the second preset time is 10-15 minutes.
In one embodiment, after pre-mixing for 20 to 30 minutes, a second mixture with uniformly distributed powdered activated carbon and binder is obtained, then the second mixture with uniformly distributed powdered activated carbon and binder and the functional filter material are put into a three-dimensional stirrer to be uniformly mixed for 10 to 15 minutes, and then the first mixture with uniformly distributed powdered activated carbon, binder and functional filter material is obtained after mixing. When the functional activated carbon product needs to be produced, other filter materials need to be added, once the specific gravity of the filter materials is much higher than that of the activated carbon and the adhesive, the density of the functional filter materials needs to be higher than that of the activated carbon and the adhesive, and the functional filter materials with relatively high density are deposited at the bottom of the stirring barrel by adopting a common stirrer and cannot be uniformly mixed at all; and adopt three-dimensional mixer to make second mixture and functional filter material mix 10 to 15 minutes, make the misce bene carry out 360 rolling, secondly three-dimensional mixer range is big, the frequency is low, so not only can be with the material misce bene, also need not worry that the in-process that rolls makes the active carbon and the adhesive separation of originally misce bene simultaneously, guarantees that active carbon, adhesive and functional filter material in the mixture are continuous, evenly distributed.
