[0030] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] See also Figure 1 , Figure 1 It is a schematic diagram of the structure of the device for preparing foamed ceramic slurry provided in the embodiment of the present application. The present application provides a device 100 for preparing foamed ceramic slurry. The device 100 for preparing foamed ceramic slurry includes a slurry pool 101 and a dust recovery and processing device 102. The dust recovery and processing device 102 is used to recover and process fine powder generated in the process of preparing foamed ceramics. The slurry pool 101 is connected to the dust recovery and processing device 102. It can be understood that after the dust recovery and processing device 102 transfers the recovered slurry-uniform dust to the slurry pool 101, the uniform slurry in the slurry pool 101 is passed into the drying tower for granulation. The drying tower is a mechanical equipment for the material drying process. In the embodiment of the present application, the drying tower is described as a spray drying tower as an example.

[0032] For further information, see Figure 2 , Figure 2 yes Figure 1 The schematic diagram of the structure of the dust recovery and treatment device 102 is shown. The dust recovery and treatment device 102 includes a collecting component 10 and a processing component 20 connected to the collecting component 10. The collecting component 10 is used to collect dust. Among them, in the embodiment of the present application, the dust is a fine powder as an example for description. The processing component 20 is provided with a feed port 201 and a discharge port 202. The feed port 201 connects the processing component 20 and the collecting component 10. The processing component 20 is used to slurry the dust entering from the feed port 201. The discharge port 202 connects the processing component 20 and the pulp pool 101, so that the slurried dust is discharged to the pulp pool and then enters the drying tower.

[0033] In one embodiment, the collection assembly 10 includes a screw conveyor 11 and a bag dust collector 12. The discharge port of the screw conveyor 11 is connected to the feed port 201. Multiple feed ports of the screw conveyor 11 are connected to the bag dust collector 12. The discharge port of the bag dust collector 12 is far away from the discharge port on one side of the screw conveyor 11. The discharge port of the bag dust collector 12 is far away from the discharge port on one side of the screw conveyor 11, so that all the dust collected by the screw conveyor 11 can enter the processing assembly 20 for slurrying.

[0034] The bag filter 12 is used to collect dust, and the screw conveyor 11 is used to convey the dust collected by the bag filter 12 to the feed port 201. In the embodiment of the present application, the use of the screw conveyor 11 enables the dust collected by the bag filter 12 to effectively enter the processing assembly 20 from one feed port 201, thereby avoiding the need to set multiple feed ports 201 in the processing assembly 20 to increase the volume of the processing assembly 20.

[0035] It can be understood that in the embodiment of the present application, the bag filter 12 collects the fine powder generated in the process of preparing foamed ceramics, and the collected fine powder is transmitted to the feed port 201 of the processing component 20 through the screw conveyor 11. The fine powder entering the feed port 201 is homogenized by the processing component 20, discharged from the slurry outlet pipe into the slurry pool 101 and then enters the drying tower for granulation, thereby realizing the recovery and reuse of the fine powder.

[0036] The processing assembly 20 includes a pulping tank 21, a stirrer 22 and a driving member 23. The pulping tank 21 is surrounded by a receiving tank 210. The receiving tank 210 is connected to the feed port 201. It can be understood that the feed port 201 is connected to the pulping tank 21 and the collecting assembly 10. The stirrer 22 is partially or completely received in the receiving tank 210. Figure 2 As shown, in the embodiment of the present application, the mixer 22 is completely accommodated in the receiving tank 210 as an example for description. In other embodiments, the mixer 22 can also be partially accommodated in the receiving tank 210, and the present application is not limited thereto.

[0037] The driving member 23 is used to drive the agitator 22 to rotate. Among them, a liquid for slurrying dust is provided in the pulping tank 21. In the embodiment of the present application, the description is made by taking water as an example of the liquid. When the dust enters the pulping tank 21 from the feed port 201 and mixes with the water in the pulping tank 21, the agitator 22 rotates under the drive of the driving member 23 to stir and break up the dust, so that the dust is evenly dissolved in the water, avoiding agglomeration when a large amount of dust is mixed into the water together, so there is no need to re-use the ball mill for mixing and homogenization, thereby simplifying the entire recycling process and accelerating the recycling efficiency.

[0038] It can be understood that the foamed ceramic dust removal and recycling device provided in the present application realizes the hydration, breaking up of clumps and mixing of dust recovery materials, and can be directly introduced into the slurry pool for homogenization, thereby simplifying the recycling process and improving the recycling efficiency.

[0039] In one embodiment, the dust recovery and processing device 102 further includes a cover plate 24. The cover plate 24 is a movable part. The cover plate 24 covers the opening of the pulping tank 21 facing the screw conveyor 11, and the driving member 23 is installed on the cover plate 24. Figure 2 As shown, the driving member 23 and the mixer 22 are respectively located on two sides of the cover plate 24 .

[0040] In the embodiment of the present application, the dust recovery and processing device 102 is provided with a cover plate 24 for covering the pulping tank 21. On the one hand, the cover plate 24 can be used to support and fix the driving member 23, and on the other hand, the cover plate 24 can cover the opening of the pulping tank 21 to prevent dust from floating into the air from the opening of the pulping tank 21.

[0041] For further information, please also refer to Figure 2 The mixer 22 includes a stirring rod 221 and a plurality of stirring blades 222 arranged at intervals along the stirring rod 221. The stirring rod 221 drives the plurality of stirring blades 222 to rotate under the drive of the driving member 23. The plurality of stirring blades 222 can effectively disperse the dust entering from the feed port 201, thereby preventing agglomeration.

[0042] The mixer 22 includes a first mixer 223 and a second mixer 224 spaced apart from the first mixer 223. The first mixer 223 is closer to the feed port 201 than the second mixer 224, and the number of the stirring blades 222 in the first mixer 223 is greater than the number of the stirring blades 222 in the second mixer 224.

[0043] like Figure 2 As shown, the first mixer 223 is located between the second mixer 224 and the feed port 201, and the number of the stirring blades 222 in the first mixer 223 is greater than the number of the stirring blades 222 in the second mixer 224. Since the first mixer 223 is closer to the feed port 201 than the second mixer 224, the dust entering the pulping tank 21 is first stirred by the first mixer 223, and then stirred by the second mixer 224. At this time, the number of the stirring blades 222 in the first mixer 223 is greater than the number of the stirring blades 222 in the second mixer 224, so that the first mixer 223 can effectively break up the dust falling on the pulp surface, so that the processing assembly 20 can effectively homogenize the dust.

[0044] In one embodiment, the driving member 23 includes a first driving member 231 and a second driving member 232. The first driving member 231 is used to drive the first mixer 223 to rotate. The second driving member 232 is used to drive the second mixer 224 to rotate, and the speed at which the first driving member 231 drives the first mixer 223 to rotate is greater than the speed at which the second driving member 232 drives the second mixer 224 to rotate. That is, the speed at which the first mixer 223 stirs is greater than the speed at which the second mixer 224 stirs. It can be understood that the first mixer 223 stirs at a high speed relative to the second mixer 224. The stirring speed of the first mixer 223 is high, and the stirring speed of the second mixer 224 is low relative to the stirring speed of the first mixer 223.

[0045] In the embodiment of the present application, since the first mixer 223 is closer to the feed port 201 than the second mixer 224, the stirring rate of the first mixer 223 is higher, which is conducive to breaking up the dust falling from the feed port 201 to the slurry surface, thereby achieving faster homogenization and avoiding agglomeration.

[0046] The first agitator 223 and the second agitator 224 rotate in the same direction.

[0047] In the embodiment of the present application, the first agitator 223 and the second agitator 224 rotate in the same direction, so that the mud in the pulping tank 21 is stirred in the same direction to avoid bubbles in the mud in the pulping tank 21.

[0048] Furthermore, the first stirrer 223 includes multiple layers of first stirring blades 2231 arranged at intervals. The multiple layers of first stirring blades 2231 are arranged along the extending direction of the stirring rod 221. Figure 2 As shown, in the embodiment of the present application, the number of layers of the first stirring blade 2231 is 5 layers as an example for description. In other embodiments, the number of layers of the first stirring blade 2231 can also be 4 layers, 7 layers or other layers, which is not limited in the embodiment of the present application. It can be understood that the multiple layers of the first stirring blade 2231 are arranged along the extension direction of the stirring rod 221, so that when the liquid in the pulping tank 21 is at different liquid levels, the multiple layers of the first stirring blade 2231 can ensure that the distance between the first stirring blade 2231 and the liquid surface is small.

[0049] In the embodiment of the present application, a certain amount of water is now added to the pulping tank 21. With the addition of dust from the feed port 201, the slurry surface will continue to rise. The first mixer 223 includes multiple layers of first stirring blades 2231 arranged in sequence, so that the distance between the first stirring blades 2231 and the slurry surface is small, which is conducive to breaking up the dust that falls on the slurry surface and avoiding a large amount of dust from accumulating on the slurry surface and causing dust to agglomerate. It can be understood that if the first stirring blade 2231 is far away from the slurry surface, the dust that falls on the slurry surface cannot be effectively broken up and is easy to agglomerate.

[0050] In one embodiment, the second mixer 224 includes one or more layers of second stirring blades 2241. Optionally, the number of layers of the second stirring blades 2241 is less than the number of layers of the first stirring blades 2231. Figure 2 As shown, in the embodiment of the present application, the number of layers of the first stirring blade 2231 is 5 and the number of layers of the second stirring blade 2241 is 2 for description. In other embodiments, the number of layers of the first stirring blade 2231 and the second stirring blade 2241 can also be other numbers, which is not limited in the present application.

[0051] Furthermore, the distance between the first stirring blade 2231 at the farthest layer from the bottom of the pulping tank 21 and the bottom of the pulping tank 21 is a first distance. The distance between the second stirring blade 2241 at the farthest layer from the bottom of the pulping tank 21 and the bottom of the pulping tank 21 is a second distance, and the second distance is smaller than the first distance. Figure 2 As shown, the first distance is marked with D1, the second distance is marked with D2, and D2 is smaller than D1.

[0052] It can be understood that the distance between the second stirring blade 2241 and the slurry surface is greater than the distance between the first stirring blade 2231 and the slurry surface, so that the second stirring blade 2241 is at a certain distance from the slurry surface, and the dust floating on the slurry surface at the position of the second mixer 224 can be dissolved in the slurry, thereby avoiding the stirring force of the mixer 22 causing the dust floating on the slurry surface to be unable to dissolve in the slurry.

[0053] In the embodiment of the present application, the distance between the stirring blade 222 of the second stirrer 224 and the slurry surface is greater than the distance between the stirring blade 222 of the first stirrer 223 and the slurry surface, so that the dust floating on the slurry surface is dispersed and dissolved in the slurry by the first stirring blade 2231, thereby improving the effect of the processing component 20 in homogenizing the slurry. And under the stirring action of the second stirrer 224, the moisture of the slurry is uniform and does not precipitate. When the moisture of the slurry matches the moisture of the slurry in the large slurry pool, the slurry is discharged and introduced into the large slurry pool.

[0054] Please also read Figure 2 and Figure 3 , Figure 3 yes Figure 2 A schematic diagram of the structure of the processing component 20 shown in another angle. The number of stirring blades 222 in each layer of the first stirring blades 2231 is greater than the number of stirring blades 222 in each layer of the second stirring blades 2241. For example, the number of stirring blades 222 in each layer of the first stirring blades 2231 is 4, and the number of stirring blades 222 in each layer of the second stirring blades 2241 is 2; or, the number of stirring blades 222 in each layer of the first stirring blades 2231 is 6, and the number of stirring blades 222 in each layer of the second stirring blades 2241 is 2. The present application does not limit the number of stirring blades 222 in the first mixer 223 and the second mixer 224.

[0055] In one embodiment, the stirring blade 222 is in the shape of a circular tube, a cylinder or a drum. For example, the plurality of stirring blades 222 in the first stirrer 223 are all in the shape of a circular tube, a cylinder or a drum. That is, the surfaces of the plurality of stirring blades 222 in the first stirrer 223 are circular.

[0056] In the embodiment of the present application, the stirring blade 222 is made of a round tube, a cylindrical or a cylindrical shape, so that the stirring resistance of the stirring blade 222 is small, thereby improving the stirring efficiency of the mixer 22.

[0057] See also Figure 3 In one embodiment, the outer contour of the pulping tank 21 is an octagon. Specifically, it is formed by splicing two halves of an inscribed octagon and a rectangle.

[0058] In the embodiment of the present application, the outer contour of the pulping tank 21 is an octagon, so that the entire pulping tank 21 occupies a small area, and the pulping tank 21 has a large capacity, which can process and recover more dust at one time, thereby improving the efficiency of the pulping treatment of dust by the treatment component 20. In other embodiments, the outer contour of the pulping tank 21 can also be a shape formed by splicing two symmetrical semicircles and a rectangle, similar to the shape of a playground runway, which is not limited by the present application.

[0059] The following is a detailed description of a dust recovery method provided by the present application in conjunction with the above-mentioned device 100 for preparing foamed ceramic slurry. In other embodiments, the dust recovery method can also be used in a device for preparing foamed ceramic slurry different from the above-mentioned embodiment. Please continue to refer to Figure 4 , Figure 4 It is a schematic flow chart of the dust recovery and treatment method provided in this application.

[0060] A dust recovery and treatment method, comprising:

[0061] S110: Collect dust.

[0062] The bag filter 12 in the apparatus 100 for preparing foamed ceramic slurry is used to collect dust.

[0063] S120: The collected dust is transferred from the feed port 201 to the pulping tank 21, in which a liquid for pulping the dust is provided.

[0064] The screw conveyor 11 in the device 100 for preparing foamed ceramic slurry is used to convey the dust collected by the bag filter 12 to the pulping tank 21. A certain amount of liquid for slurrying the dust is provided in the pulping tank 21. In the embodiment of the present application, the description is made by taking water as an example. When the dust is conveyed to the pulping tank 21 and mixed with the water in the pulping tank 21, the dust is slurried to form a slurry.

[0065] S130: Control the agitator 22 in the pulping tank 21 to rotate, dissolve the dust in the liquid, and form a uniform slurry.

[0066] During the rotation process, the mixer 22 can break up the dust that falls on the slurry surface, reducing the risk of dust agglomeration during the slurrying process. In addition, the mixer 22 can also break up the agglomerated dust during the rotation and stirring process, so that the dust is evenly mixed with the liquid to form a uniform slurry.

[0067] It can be understood that the mixer 22 rotates under the drive of the driving member 23 to stir and break up the dust, so that the dust is evenly dissolved in the water, avoiding agglomeration when a large amount of dust is mixed into the water together. Therefore, there is no need to re-use the ball mill for mixing and homogenization, thereby simplifying the entire recycling process and accelerating the recycling efficiency.

[0068] Controlling the agitator 22 in the pulping tank 21 to rotate includes: controlling the first agitator 223 to rotate at a first rate and controlling the second agitator 224 to rotate at a second rate, the first rate is greater than the second rate, and the first agitator 223 is closer to the feed port 201 than the second agitator 224 .

[0069] It is understandable that the mixer 22 provided in the present application includes at least two, namely, a first mixer 223 and a second mixer 224. Accordingly, the first mixer 223 is driven by a first driving member 231, and the second mixer 224 is driven by a second driving member 232. In one embodiment, the first mixer 223 stirs at a high speed relative to the second mixer 224. The stirring rate of the first mixer 223 is relatively high, and the stirring rate of the second mixer 224 is relatively low relative to the stirring rate of the first mixer 223.

[0070] In the embodiment of the present application, since the first mixer 223 is closer to the feed port 201 than the second mixer 224, the stirring rate of the first mixer 223 is higher, which is conducive to breaking up the dust falling from the feed port 201 to the slurry surface, thereby achieving faster homogenization and avoiding agglomeration.

[0071] The first agitator 223 rotates in the same direction as the second agitator 224. In the embodiment of the present application, the first agitator 223 rotates in the same direction as the second agitator 224, so that the mud in the pulping tank 21 is stirred in the same direction to avoid bubbles in the mud in the pulping tank 21.

[0072] S140: When the concentration of the slurry reaches the target value, the slurry is discharged to the slurry pool.

[0073] After the slurry is discharged into the slurry pool 101, the uniform slurry in the slurry pool 101 is passed into the drying tower for granulation.

[0074] In one embodiment, the device 100 for preparing foamed ceramic slurry can automatically determine whether the concentration of the slurry has reached the target value. For example, the water level in the pulping tank 21 is automatically detected and calculated according to the liquid level detector, and the weight in the pulping tank 21 is detected when the dust is continuously transported to the pulping tank 21. When the weight of the pulping tank 21 reaches the target weight, it means that the concentration of the slurry has reached the target value. At this time, the slurry can be automatically controlled to be pumped to the drying tower for drying and granulation.

[0075] In this embodiment, the device 100 for preparing foamed ceramic slurry automatically detects the concentration of the slurry, thereby realizing automation of the device 100 for preparing foamed ceramic slurry and saving labor costs.

[0076] In another embodiment, the device 100 for preparing foamed ceramic slurry can manually determine whether the concentration of the slurry reaches the target value. For example, a water level scale is provided on the wall of the pulping tank 21. The measurement personnel determine whether the concentration of the slurry is close to the target value based on the initial water level in the pulping tank 21 and the final water level after the dust is dissolved. When the water level of the slurry reaches the target water level, the measurement personnel take the slurry in the pulping tank 21 to measure its concentration. When the measured concentration reaches the target value, the slurry is controlled to be pumped to the drying tower for drying and granulation.

[0077] In this embodiment, the measurement personnel detect the concentration of the slurry, and can more accurately discharge the slurry reaching the target value to the slurry pool 101, so that the slurry enters the drying tower for granulation, thereby improving the reliability of granulation.

[0078] It can be understood that the dust recovery method provided in the present application realizes the hydration, breaking up of clumps and mixing of dust recovery materials, and can be directly introduced into the slurry pool for homogenization without the need to re-use the ball mill for mixing and homogenization, thereby simplifying the entire recovery process and improving the recovery efficiency.
