Description

Technical Field

[0001] This invention relates to the field of sludge drying technology, specifically a micro-air chamber for sludge drying. Background Technology

[0002] In the process of sludge resource utilization, sludge drying is a crucial step; sludge air drying involves spreading out the sludge after mixing and turning it over, exposing it to the surrounding air, and using natural drying resources such as wind and sunlight to evaporate some of the moisture in the sludge until it becomes dry.

[0003] Existing technologies also include technical solutions for sludge drying chambers. For example, a Chinese patent application with patent number CN2014204796078 discloses a sludge drying chamber, which includes: an air supply system, a feeding system, and a conveying system. The air supply system includes a chamber body, a fan wall, and an exhaust gas purifier. The chamber body is a tunnel-type closed structure, with the fan wall at one end and the exhaust gas purifier at the other end. The fan wall is composed of multiple fans, with the fan inlets located outside the chamber body. Through the combined action of the feeding system and the conveying system, the sludge is spread into a thin layer, and the air supply system allows air to flow over the sludge and dry it.

[0004] However, existing air-drying chambers have the following problems when drying sludge: continuous air blowing makes the sludge dry slowly, and the surface of the sludge is dry while the inside is still moist. Therefore, the air-drying chamber has a poor drying effect on sludge and is not conducive to the complete drying of sludge. To address this, the present invention provides a micro-air chamber for drying sludge. Summary of the Invention

[0005] The technical problem solved by this invention is that continuous air blowing to dry sludge results in a slow drying speed, and while the surface of the sludge is dry, the interior remains damp. Therefore, the drying chamber has a poor drying effect on the sludge and is not conducive to the complete drying of the sludge.

[0006] The present invention can be achieved through the following technical solution: a micro-air chamber for sludge drying, comprising a chamber body, a feeding shell fixedly connected to the top of the chamber body, a feeding trough fixedly connected to the bottom of the feeding shell, a slicing assembly disposed inside the feeding trough, the slicing assembly comprising a cutting plate and a baffle, the cutting plate penetrating and slidably connected to one side of the feeding trough, the baffle penetrating and slidably connected to the other side of the feeding trough, and the baffle being located below the cutting plate, and a gap for forming sludge flakes being provided between the baffle and the cutting plate.

[0007] A further technical improvement of the present invention is that: the side wall of the feeding trough is also connected to a plurality of dispersing rods through and slidably, and a second push plate is fixedly connected to one end of the dispersing rod outside the feeding trough, and a magnetic protrusion is fixedly connected to the bottom of the second push plate on the side near the feeding trough.

[0008] A further technical improvement of the present invention is that: a push plate is fixedly connected to the side of the cutting plate outside the feeding groove, and a second magnetic protrusion is fixedly connected to the top of the first push plate on the side away from the feeding groove, and the first magnetic protrusion is located to the left of the second magnetic protrusion.

[0009] A further technical improvement of the present invention is that: the inside of the feeding trough is also rotatably connected to a swing rod, a torsion spring is provided on the rotating shaft of the swing rod, and the swing rod is located above the cutting plate.

[0010] A further technical improvement of the present invention is that: the baffle has a groove on the side near the first push plate, a slide plate is slidably connected in the groove, and a plurality of straight rods are fixedly connected at equal intervals to the top of the slide plate, the top of the straight rods passing through and slidably connected to the top of the baffle.

[0011] A further technical improvement of the present invention is that: a plurality of springs are fixedly connected to the bottom of the slide plate, and the bottom end of the springs is fixedly connected to the bottom of the slide groove; a triangular block is fixedly connected to the side of the slide plate outside the slide groove, and a right-angled trapezoidal block is fixedly connected to the bottom of the first push plate, and the triangular block and the right-angled trapezoidal block are in a sliding engagement state.

[0012] A further technical improvement of the present invention is that: the interior of the silo is provided with multiple walking conveyor belts, which are arranged vertically at intervals, and the same side of two adjacent walking conveyor belts is not aligned; multiple fans are fixedly installed on the inner wall of the silo.

[0013] A further technical improvement of the present invention is that: a first sprocket is fixedly connected to the rotating roller of the conveyor belt, a reduction gearbox is installed on the top of the bin, a second sprocket is also fixedly connected to the output end of the reduction gearbox, a third sprocket is rotatably connected to the top of the bin, and a fourth sprocket is rotatably connected to the bottom side wall of the bin.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this invention, the bottom of the feeding trough is sealed by a baffle, allowing the cutting plate to extend further into the feeding trough. In conjunction with the baffle, the sludge is sliced, increasing the contact area between the sludge and the air, which is beneficial for the rapid drying of the sludge. By pushing the baffle to the left, the bottom of the feeding trough is opened, allowing the sludge slices below the cutting plate to fall onto the conveyor belt. The sludge is then dried by the fan on the inner wall of the silo and continuously conveyed downwards, ultimately achieving the drying of the sludge.

[0016] 2. In this invention, when the No. 1 electric cylinder drives the No. 2 push plate and the No. 1 push plate to move to the left to slice the sludge, the dispersing rod will also break up the sludge, preventing sludge from clumping and improving the drying effect of the sludge. When the cutting plate moves to the left and contacts the inner wall of the left side of the feeding trough, the No. 1 magnetic protrusion and the No. 2 magnetic protrusion separate, causing the dispersing rod to continue moving to the left and squeezing the swing rod, causing the swing rod to rotate slightly counterclockwise and hit the cutting plate, making the cutting plate vibrate, which will help the sludge slices fall off from the bottom of the cutting plate.

[0017] 3. In this invention, when the No. 1 electric cylinder drives the No. 2 push plate and the No. 1 push plate to move to the left to slice the sludge, the inclined surface of the right-angled trapezoidal block will press against the inclined surface of the triangular block, causing the triangular block to drive the sliding plate to move upward. The sliding plate drives the straight rod to move upward and extend the baffle to contact the sludge. This not only breaks down the sludge but also creates multiple holes on the surface of the sludge slices, increasing the contact area between the sludge and the air, and facilitating the rapid drying of the sludge.

[0025] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0026] Please see Figures 1-5 As shown, a micro-air chamber for sludge drying includes a chamber body 1, with a feeding shell 2 fixedly connected to the top of the chamber body 1. Multiple conveyor belts 3 are arranged inside the chamber body 1, with the conveyor belts 3 arranged parallel to each other vertically and at intervals. The same side of two adjacent conveyor belts 3 is not aligned, while the same side of two non-adjacent conveyor belts 3 is aligned. Multiple fans are fixedly installed on the inner wall of the chamber body 1 to dry the sludge sheets on top of the conveyor belts 3. During operation, the sludge to be dried is placed into the feeding shell 2, allowing it to discharge from the bottom of the shell 2 and fall onto the top of the conveyor belts 3. The fans around the conveyor belts 3 then dry the sludge. As the sludge on the top of the same conveyor belt 3 is transported from one side to the other, the sludge falls onto the top of the conveyor belt 3 below, where the fans on the inner wall of the chamber body 1 continue to dry it. This process is repeated until the sludge is completely dried.

[0027] The driving mechanism for the walking conveyor belt 3 is a combination of sprockets and chains 5. Specifically, a motor 6 and a gearbox 4 are installed on the top of the silo 1. The motor 6 is connected to the input end of the gearbox 4, and a second sprocket 22 is fixedly connected to the output end of the gearbox 4. A first sprocket 23 is fixedly connected to the roller of each walking conveyor belt 3. A third sprocket 24 is rotatably connected to the top of the silo 1, and a fourth sprocket 25 is rotatably connected to the inner wall at the bottom of the silo 1. The multiple first sprockets 23, first and second sprockets 22, a third sprocket 24, and a fourth sprocket 25 are connected together by chains 5. During operation, the motor 6 drives the second sprocket 22 to rotate, which, in conjunction with the transmission of the chains 5, causes the walking conveyor belt 3 to start working. The sludge conveying directions of two adjacent walking conveyor belts 3 are opposite, allowing the sludge to be horizontally and reciprocally conveyed at different heights inside the silo 1.

[0028] Furthermore, to increase the contact area between the sludge and air and to eliminate the need for manual sludge spreading, a corresponding slicing component is installed. The specific structure is as follows: a feeding trough 7 is fixedly connected to the bottom of the feeding shell 2; a cutting plate 8 and a baffle 9 are slidably connected through and to both sides of the feeding trough 7; the cutting plate 8 is slidably connected through and to one side of the feeding trough 7, and the baffle 9 is slidably connected through and to the other side of the feeding trough 7, with the baffle 9 located below the cutting plate 8; a space for forming sludge is provided between the baffle 9 and the cutting plate 8. The gap between the sludge flakes; initially, the bottom of the feeding trough 7 is closed by the baffle 9, and the cutting plate 8 is located on the rightmost wall of the feeding trough 7. When the sludge enters the feeding trough 7, the cutting plate 8 extends further into the feeding trough 7, and with the action of the baffle 9, the sludge is sliced. After slicing, the cutting plate 8 stays in the same position and pushes the baffle 9 to the left, so that the bottom of the feeding trough 7 is open, and the sludge flakes below the cutting plate 8 fall down onto the traveling conveyor belt 3.

[0029] The cutting plate 8 is driven by the first electric cylinder, and the baffle 9 is driven by the second electric cylinder. The first and second electric cylinders are fixedly installed at the bottom of the feeding shell 2.

[0030] Furthermore, multiple dispersing rods 10 are slidably connected through the side wall of the feeding trough 7, and a second push plate 11 is fixedly connected to one end of the dispersing rod 10 outside the feeding trough 7; as the cutting plate 8 extends further into the feeding trough 7, the dispersing rods 10 will poke the sludge inside the feeding trough 7, thereby breaking up the sludge, preventing the sludge from clumping, and improving the drying effect of the sludge.

[0031] Furthermore, a magnetic protrusion 12 is fixedly attached to the bottom of the second push plate 11 on the side near the feeding trough 7; a push plate 13 is fixedly attached to the side of the cutting plate 8 outside the feeding trough 7, and a magnetic protrusion 14 is fixedly attached to the top of the first push plate 13 on the side away from the feeding trough 7, with the first magnetic protrusion 12 located to the left of the second magnetic protrusion 14; the first push plate 13 and the second push plate 11 are connected together by the magnetic force of the first magnetic protrusion 12 and the second magnetic protrusion 14. When the second push plate 11 is driven to move to the left by the first electric cylinder to slice the sludge, the dispersing rod 10 will also crush the sludge.

[0032] Furthermore, the inside of the feeding trough 7 is rotatably connected to the swing rod 15. A torsion spring is installed on the rotating shaft of the swing rod 15, and the swing rod 15 is located above the cutting plate 8. When the first electric cylinder drives the second push plate 11 to move to the left to slice the sludge, the dispersing rod 10 will also crush the sludge. When the cutting plate 8 moves to the left limit position and contacts the inner wall of the left side of the feeding trough 7, the cutting plate 8 stops moving to the left, while the first electric cylinder continues to drive the second push plate 11 to move to the left, causing the first magnetic protrusion 12 and the second magnetic protrusion 14 to separate. When the dispersing rod 10 continues to move to the left, it will squeeze the swing rod 15, causing the swing rod 15 to rotate slightly counterclockwise and hit the cutting plate 8, making the cutting plate 8 vibrate, which will help the sludge slices fall off from the bottom of the cutting plate 8. After the dispersing rod 10 leaves the swing rod 15, the swing rod 15 will return to its initial position due to the action of the torsion spring.

[0033] To further increase the contact area between the sludge flakes and the air, a chute 16 is provided on the side of the baffle 9 near the first push plate 13. A slide plate 17 is slidably connected inside the chute 16. Multiple straight rods 18 are fixedly connected at equal intervals to the top of the slide plate 17, and the top of the straight rods 18 passes through and is slidably connected to the top of the baffle 9. Multiple springs 21 are fixedly connected to the bottom of the slide plate 17, and the bottom ends of the springs 21 are fixedly connected to the bottom of the chute 16. A triangular block 19 is fixedly connected to the side of the slide plate 17 outside the chute 16, and a right-angled trapezoidal block 20 is fixedly connected to the bottom of the first push plate 13. The triangular block 19 and the right-angled trapezoidal block 20 are in a sliding engagement state. When the first electric cylinder drives the second push plate 11 to move to the left, the sludge is cut. At the same time, the first push plate 13 drives the right-angled trapezoidal block 20 to move to the left, so that the inclined surface of the right-angled trapezoidal block 20 presses against the inclined surface of the triangular block 19, causing the triangular block 19 to drive the slide plate 17 to move upward. At the same time, the spring 21 is stretched, and the slide plate 17 drives the straight rod 18 to move upward and extend the baffle 9 to contact the sludge. This not only crushes the sludge, but also creates multiple holes on the surface of the formed sludge sheet, increasing the contact area between the sludge and the air, which facilitates the rapid drying of the sludge. When the right-angled trapezoidal block 20 separates from the triangular block 19, the elastic force of the spring 21 will cause the straight rod 18 to retract into the wall of the baffle 9, making it easy for the baffle 9 to slide on the side wall of the feeding trough 7.

[0034] In use, initially, the second electric cylinder drives the baffle 9 to extend into the feeding trough 7, sealing the bottom of the feeding trough 7. The cutting plate 8 is then located on the rightmost wall of the feeding trough 7. After entering the feeding trough 7 from the upper shell 2, the first electric cylinder drives the second push plate 11 and the first push plate 13 to move to the left, causing the cutting plate 8 to extend further into the feeding trough 7. Working in conjunction with the baffle 9, this slices the sludge. After slicing, the cutting plate 8 remains stationary. The second electric cylinder then moves the baffle 9 to the left, opening the bottom of the feeding trough 7, thus allowing the sludge to be sliced. The sludge flakes below plate 8 fall onto the traveling conveyor belt 3, where they are dried by fans around the conveyor belt 3. As sludge on the top of the same traveling conveyor belt 3 is transported from one side to the other, the sludge on the top of the traveling conveyor belt 3 falls onto the top of the traveling conveyor belt 3 below, where it continues to be dried by fans on the inner wall of the silo 1. This process is repeated until the sludge is completely dried. When the first electric cylinder drives the second push plate 11 to move to the left to slice the sludge, the dispersing rod 10 will agitate the feeding chute. The sludge inside the feed trough 7 is broken up to prevent sludge clumping and improve the drying effect. When the cutting plate 8 moves to its left limit and contacts the inner wall of the left side of the feed trough 7, the cutting plate 8 stops moving to the left. The first electric cylinder continues to drive the second push plate 11 to move to the left, causing the first magnetic protrusion 12 and the second magnetic protrusion 14 to separate. As the dispersing rod 10 continues to move to the left, it will squeeze the swing rod 15, causing the swing rod 15 to rotate slightly counterclockwise and impact the cutting plate 8, making the cutting plate 8 vibrate. This will help the sludge pieces to detach from the bottom of the cutting plate 8. When the No. 1 electric cylinder drives the No. 2 push plate 11 to move to the left to slice the sludge, the No. 1 push plate 13 drives the right-angled trapezoidal block 20 to move to the left, so that the inclined surface of the right-angled trapezoidal block 20 presses against the inclined surface of the triangular block 19, so that the triangular block 19 drives the slide plate 17 to move upward, and at the same time, the spring 21 is stretched. The slide plate 17 drives the straight rod 18 to move upward and extends the baffle 9 to contact the sludge. This not only breaks down the sludge, but also makes the surface of the sludge slices have multiple holes, increasing the contact area between the sludge and the air, which facilitates the rapid drying of the sludge.
