Abstract
Description
Technical Field
[0001] This utility model relates to the field of fly ash treatment and screening technology, specifically to a fly ash treatment and screening device for producing concrete blocks using solid waste. Background Technology
[0002] As one of the largest industrial solid wastes emitted by coal-fired power plants, fly ash poses a significant challenge in the production of concrete blocks. Untreated fly ash, due to its uneven particle size, high carbon content, and excessive impurities, can lead to reduced block strength and insufficient durability, failing to meet the requirements of the "Grading Standard for Fly Ash Used in Cement and Concrete". To achieve accurate grading and purification of fly ash, the use of fly ash treatment and screening devices for the production of concrete blocks from solid waste has become a key link between solid waste resource utilization and green building materials.
[0003] In the existing technology, when the fly ash treatment and screening device is in use, the blades are driven to rotate by the rotating shaft inside the barrel. The fly ash is pushed by the blades and slides against the barrel wall. The fine powder passes through the filter holes under the action of centrifugal force for screening. After long-term use, the fine powder tends to adhere to the edges of the filter holes on the surface of the screen barrel. The accumulation of fine powder can easily cause blockage and affect the screening effect of raw materials. Utility Model Content
[0004] To overcome the above-mentioned defects, the present invention provides a fly ash treatment and screening device for producing concrete blocks from solid waste, which solves the technical problem that the screen barrel is prone to clogging after long-term use in the prior art.
[0005] According to one aspect, at least one embodiment of the present invention provides a fly ash treatment and screening device for producing concrete blocks from solid waste, comprising: The working box has a collection component at its bottom, and a support plate is fixedly installed at the bottom of the working box on the front and rear sides of the collection component. A feed inlet is provided at the upper part of one end of the working box, and a discharge outlet is provided at the bottom end of the working box. A screening component is located inside the working box, and the bottom end of the feed inlet passes through the working box and is fixedly connected to the top end of the screening component. A scraping component is disposed on the outer surface of the screening component, and the scraping component is used to clean the outer surface of the screening component; A rotating mechanism is located on one side of the screening component and is fixedly connected to the scraping component to facilitate cleaning of the screening component.

The other end of the connecting rod is fixedly installed on the other end inside the working box, and a waste discharge port is provided at the bottom of one end of the screen barrel.
[0007] For example, at least one embodiment of this utility model provides a fly ash treatment and screening device for producing concrete blocks from solid waste. The screening component further includes a fixing plate. One side wall of the fixing plate is fixedly installed on one side wall of the outer wall of the working box. A first motor is fixedly installed on the upper end of the fixing plate. The output end of the first motor extends through the working box and the screen barrel into the interior. A first bearing is provided at the connection between the output end of the first motor and the working box and the screen barrel. The inner ring surface of the first bearing is fixedly connected to the outer surface of the output end of the first motor. The outer ring surface of the first bearing is fixedly connected to the connection between the working box and the screen barrel. A rotating shaft is fixedly connected to the output end of the first motor. Rotating blades are fixedly installed on the surface of the rotating shaft.
[0008] For example, at least one embodiment of this utility model provides a fly ash treatment and screening device for producing concrete blocks from solid waste. The rotating mechanism includes a connecting block, which is fixedly mounted on the other side wall of the working box. A second motor is fixedly installed on the upper end of the connecting block. The output end of the second motor extends through the working box and into the interior. A second bearing is provided at the connection between the output end of the second motor and the working box. The inner ring surface of the second bearing is fixedly connected to the outer surface of the output end of the second motor. The outer ring surface of the second bearing is fixedly connected to the connection between the working box and the second motor. An active toothed plate is fixedly installed at the output end of the second motor. A driven toothed plate is meshed on one side of the active toothed plate.
[0009] For example, at least one embodiment of this utility model provides a fly ash treatment and screening device for producing concrete blocks from solid waste. The driven toothed plate is provided with several sets of rollers equidistantly arranged on the side near the second motor. A through hole is opened in the middle of the driven toothed plate. A third bearing is arranged in the through hole. The outer ring surface of the third bearing is fixedly connected to the inner wall of the through hole. The inner ring surface of the third bearing is fixedly connected to the outer surface of the connecting rod. A T-shaped groove is opened on the inner wall of the working box near the second motor. The rollers are slidably connected inside the T-shaped groove.
[0010] For example, at least one embodiment of this utility model provides a fly ash treatment and screening device for producing concrete blocks from solid waste.

The collection component includes a storage box, which is placed at the bottom of the working box directly below the discharge port. A partition is fixedly installed inside the storage box.
[0013] The beneficial effects of this utility model are as follows: In this invention, the second motor starts and drives the active toothed plate to rotate through the output shaft. The active toothed plate meshes with the driven toothed plate, realizing the rotation of the driven toothed plate. When the driven toothed plate rotates, it drives the connecting plate to rotate synchronously through the connecting shaft, thereby causing the brush to make a circular motion along the outer surface of the screen barrel. The direction of rotation is opposite to the direction of rotation of the rotating blades inside the screen barrel, forming relative motion, which enhances the shearing force on the adhering fine powder and can improve the cleaning effect to a certain extent. The end of the connecting plate away from the connecting shaft is embedded in the annular groove through the connecting post. When the brush rotates, the connecting post slides along the annular groove, limiting the displacement of the connecting plate and ensuring the stable contact between the brush and the outer surface of the screen barrel.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0023] like Figure 1 and Figure 2 As shown, it illustrates a fly ash treatment and screening device for producing concrete blocks from solid waste according to one embodiment of the present invention, comprising: The working box 1 has a collection component 2 at the bottom. The bottom of the working box 1 is fixedly installed with a support plate 5 on the front and rear sides of the collection component 2. The upper part of one end of the working box 1 has a feed inlet 12, and the bottom of the working box 1 has a discharge outlet 6. The collection component 2 facilitates the collection of the screened fly ash. The screening component 3 is located inside the working box 1. The bottom end of the feed inlet 12 passes through the working box 1 and is fixedly connected to the top end of the screening component 3. The screening component 3 performs screening work on the raw materials fed in from the feed inlet 12. Scraping component 9 is set on the outer surface of screening component 3. Scraping component 9 is used to clean the outer surface of screening component 3 and to a certain extent avoid clogging of the screening holes on the surface of screening component 3. Rotating mechanism 4 is located on one side of screening component 3. Rotating mechanism 4 is fixedly connected to scraping component 9 to facilitate cleaning of screening component 3.
[0024] In some examples, such as Figure 2 As shown, the screening component 3 includes a screen barrel 32. One end of the screen barrel 32 is fixedly installed on one side wall inside the working box 1, and a connecting rod 33 is fixedly installed on the other end of the screen barrel 32. The other end of the connecting rod 33 is fixedly installed on the other end inside the working box 1. A waste discharge port 11 is opened at the bottom of one end of the screen barrel 32.
[0025] Coarse powder that cannot pass through the sieve holes is continuously pushed by the blades to the right end of the sieve barrel 32, and finally falls into the discharge port 6 of the working box 1 through the waste discharge port 11 at the bottom, and then enters the collection component 2.
[0026] In some examples, such as Figure 2 and Figure 3As shown, the screening component 3 also includes a fixing plate 35. One side wall of the fixing plate 35 is fixedly installed on the outer side wall of the working box 1. A first motor 31 is fixedly installed on the upper end of the fixing plate 35. The output end of the first motor 31 extends through the working box 1 and the screen barrel 32 into the interior. A first bearing 34 is provided at the connection between the output end of the first motor 31 and the working box 1 and the screen barrel 32. The inner ring surface of the first bearing 34 is fixedly connected to the outer surface of the output end of the first motor 31. The outer ring surface of the first bearing 34 is fixedly connected to the connection between the working box 1 and the screen barrel 32. A rotating shaft is fixedly connected to the output end of the first motor 31. Rotating blades are fixedly installed on the surface of the rotating shaft.
[0027] Fly ash falls into the screen barrel 32 through the feed inlet of the working box 1. The first motor 31 starts, driving the rotating shaft and rotating blades to rotate. The spiral structure of the blades pushes the fly ash to move along the axial direction of the screen barrel 32. At the same time, the arc-shaped blades disperse the material and stick it to the barrel wall to avoid material accumulation. The fly ash can evenly contact the screening holes on the wall of the screen barrel 32. When the fly ash moves along the barrel wall under the push of the blades, the fine powder passes through the screening holes and enters the screen barrel 32 under the action of centrifugal force generated by the rotation. Finally, it falls into the collection component 2 under the action of gravity.
[0028] In some examples, such as Figure 3 As shown, the rotating mechanism 4 includes a connecting block 47, which is fixedly mounted on the other side wall of the outer side of the working box 1. A second motor 41 is fixedly mounted on the upper end of the connecting block 47. The output end of the second motor 41 extends through the working box 1 into the interior. A second bearing 42 is provided at the connection between the output end of the second motor 41 and the working box 1. The inner ring surface of the second bearing 42 is fixedly connected to the outer surface of the output end of the second motor 41. The outer ring surface of the second bearing 42 is fixedly connected to the connection between the working box 1. An active toothed plate 43 is fixedly mounted on the output end of the second motor 41. A driven toothed plate 44 is meshed on one side of the active toothed plate 43.
[0029] The second motor 41 starts and drives the active gear plate 43 to rotate through the output shaft. The active gear plate 43 meshes with the driven gear plate 44, realizing the rotation of the driven gear plate 44.
[0030] In some examples, such as Figure 3 and Figure 4 As shown, a number of rollers 45 are equidistantly arranged on the side of the driven toothed plate 44 near the second motor 41. A through hole 8 is opened in the middle of the driven toothed plate 44. A third bearing 46 is installed in the through hole 8. The outer ring surface of the third bearing 46 is fixedly connected to the inner wall of the through hole 8. The inner ring surface of the third bearing 46 is fixedly connected to the outer surface of the connecting rod 91. A T-shaped slide groove 7 is opened on the inner wall of the working box 1 near the second motor 41. The rollers 45 are slidably connected inside the T-shaped slide groove 7.
[0031] The roller 45 is embedded in the T-shaped groove 7. When it rotates synchronously with the driven toothed plate 44, the T-shaped groove 7 restricts the displacement of the roller, ensuring the concentricity of the driven toothed plate 44 and the screen barrel 32, and avoiding uneven gaps between the brush bristles of the scraping component 9 and the surface of the screen barrel 32.
[0032] In some examples, such as Figure 3 As shown, the scraping assembly 9 includes a connecting shaft 91. One end of the connecting shaft 91 is fixedly connected to the side wall of the driven toothed plate 44 away from the second motor 41. The other end of the connecting shaft 91 is threadedly connected to a connecting plate 93 by a bolt 92. A brush 94 is fixedly installed on the side of the connecting plate 93 near the screen barrel 32. The brush 94 is in contact with the outer surface of the screen barrel 32.
[0033] When the driven toothed plate 44 of the rotating mechanism 4 rotates, it drives the three connecting plates 93 to rotate synchronously through the connecting shaft 91, thereby causing the brush 94 to make a circular motion along the outer surface of the screen barrel 32. The direction of rotation is opposite to the direction of rotation of the rotating blades inside the screen barrel 32, forming relative motion, which enhances the shearing force on the adhering fine powder and can improve the cleaning effect to a certain extent.
[0034] In some examples, such as Figure 2 and Figure 3 As shown, an annular groove 10 is provided on one side wall of the working box 1 near the first motor 31, and a connecting column 95 is fixedly installed on the other end of the connecting plate 93. The connecting column 95 is slidably installed in the annular groove 10.
[0035] The end of the connecting plate 93 away from the connecting shaft 91 is embedded in the annular groove 10 through the connecting post 95. When the brush 94 rotates, the connecting post 95 slides along the annular groove, which restricts the displacement of the connecting plate 93 and ensures that the brush 94 and the outer surface of the screen barrel 32 are stably attached.
[0036] In some examples, such as Figure 5 As shown, the collection component 2 includes a storage box 21, which is placed at the bottom of the working box 1 directly below the discharge port 6. A partition 22 is fixedly installed inside the storage box 21.
[0037] The partition 22 can separate and collect fine powder and coarse powder. The fine powder sieved by the screen barrel 32 falls into the gap between the working box 1 and the screen barrel 32 after passing through the screen holes. Under the action of gravity, it enters one side of the partition 22 of the storage box 21 along the bottom of the working box 1. The coarse powder pushed by the rotating blades inside the screen barrel 32 is discharged through the waste outlet 11 at the bottom right end of the screen barrel 32 and falls directly into the discharge outlet 6 at the bottom of the working box 1, and finally enters the other side of the partition 22.
[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
