Description

Technical Field

[0001] This utility model belongs to the field of porous brick processing technology, and in particular relates to a high-efficiency screening device for porous brick processing. Background Technology

[0002] Porous bricks are finished bricks made from coal gangue or fluidized bed slag discharged from coal mines as the main raw materials, with the addition of a certain amount of quicklime and gypsum, and are obtained through pressure molding and steam curing. The main production process includes four parts: raw material preparation, proportioning and digestion, pressing and molding, and steam curing. Among them, when processing the raw materials for porous bricks, a screening device is required to perform fine screening of the raw materials.

[0003] Patent application CN202421646266.9 discloses a multi-layer screening device for processing porous bricks, comprising a screen box, a support base fixedly connected to the lower surface of the screen box, a support frame fixedly connected to one side of the support base, a hydraulic cylinder fixedly connected to the upper surface of the support frame, a slide rod fixedly connected to the output end of the hydraulic cylinder, a connecting rod slidably connected to the outer wall of the slide rod, a bearing disposed inside the connecting rod, a material container fixedly connected to the outer wall of the bearing, a fixing strip fixedly connected to the outer wall of the connecting rod, and a column fixedly connected to one side of the fixing strip. In this invention, through the cooperation of the screen box, screen frame, screen mesh, and vibration components, the device achieves automatic feeding and multi-layer fine screening of raw materials, improving the utilization efficiency of the device, reducing labor intensity, decreasing noise during screening, and increasing the service life of the device.

[0004] Existing technologies employ multi-layered sieves for fine screening, but these methods still have shortcomings: First, existing screening devices directly discharge large particles when screening materials for porous brick production, without performing secondary processing on them, which reduces overall production efficiency. Secondly, when screening materials for porous brick production, the raw materials contain large particles during the initial screening. When the raw materials are turned over and stirred, the large particles are easily stuck inside the screen holes, resulting in slow material discharge and affecting the overall screening efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this invention provides a high-efficiency screening device for porous brick processing. Through the arrangement of components such as an arc-shaped screen plate, this invention can simultaneously stir and screen the porous brick raw materials, while also directing larger particles into the crushing chamber for secondary crushing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency screening device for porous brick processing, comprising a housing, wherein a rotating roller is rotatably arranged inside the housing, characterized in that an arc-shaped screen plate is arranged below the rotating roller inside the housing, and multiple flipping plates are evenly arranged on the outer circular surface of the arc-shaped screen plate, each flipping plate having multiple filter grooves on one side wall near the arc-shaped screen plate, a first discharge port is arranged on one side of the arc-shaped screen plate on the inner side wall of the housing, a connecting inclined plate is arranged between the first discharge port and the arc-shaped screen plate, a crushing component is connected to one side of the first discharge port on the outer side wall of the housing, and a secondary screening component is arranged below the arc-shaped screen plate inside the housing, the discharge end of the crushing component being connected to the secondary screening component.

[0007] Optionally, the crushing assembly includes a crushing box disposed on the outer wall of the housing, with two meshing crushing rollers rotatably disposed inside the crushing box, the input port of the crushing box being interconnected with the first discharge port, and the discharge port of the crushing box being provided with a second discharge port on the side wall of the housing.

[0008] Optionally, the secondary screening assembly includes a rotating groove disposed on the inner wall of the housing, a guide plate is inclinedly disposed on one side of the rotating groove, one end of the guide plate is rotatably connected to the rotating groove, a third discharge port is disposed on one side of the guide plate on the inner wall of the housing, the other end of the guide plate is slidably connected to the third discharge port, and a screen hole is disposed on the upper surface of the guide plate.

[0009] Optionally, a plurality of elastic telescopic rods are rotatably connected between the guide plate and the inner bottom surface of the third discharge port, and a vibrator is provided on the lower end surface of the guide plate.

[0010] Optionally, baffles are provided between the plurality of screen holes and the inclined end face of the guide plate.

[0011] Optionally, a second guide plate is provided above the connecting inclined plate on the side wall of the housing.

[0012] Optionally, a squeezing roller is rotatably arranged on one side of each of the multiple filter tanks inside the flipping plate. Each squeezing roller has multiple protrusions on its outer circular surface. A coil spring is arranged between each squeezing roller and the flipping plate at both ends. A protective shell is fixedly arranged on the inner side wall of the flipping plate on the outside of each coil spring. One end of each coil spring is fixedly connected to the inner circular surface of its adjacent protective shell, and the other end of each protrusion is fixedly connected to the outer circular surface of one end of its adjacent squeezing roller.

[0013] Optionally, a third guide plate is provided above the guide plate on the inner wall of the shell.

(2) The present invention uses components such as extrusion rollers, protrusions and coil springs to assist in the stirring and screening of porous brick raw materials inside the arc-shaped screen plate.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1:

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a high-efficiency screening device for porous brick processing includes a housing 10. A rotating roller 12 is rotatably arranged inside the housing 10. Below the rotating roller 12, an arc-shaped screen plate 11 is arranged inside the housing 10. During screening, porous brick raw materials are poured in from the upper port of the housing 10. The poured-in porous brick raw materials fall onto the inner arc surface of the arc-shaped screen plate 11, where they are screened through the sieve holes on the inner arc surface of the arc-shaped screen plate 11. Multiple flipping plates 13 are evenly arranged on the outer circular surface of the arc-shaped screen plate 11. Each flipping plate 13 has multiple filter grooves 14 on one side wall near the arc-shaped screen plate 11. Multiple through holes 15 are provided on one side of each filter groove 14 and on the side wall of each flipping plate 13. The arrangement of multiple through holes 15 increases the efficiency of screening. The agitator 13 improves the permeability during stirring, and the porous brick material in the upper layer can flow through the through hole 15 when the agitator 13 rotates, thereby further increasing the agitation effect of the multiple agitators 13 on the porous brick material, thus accelerating the screening speed and screening quality of the material inside the arc screen plate 11. A first discharge port 17 is provided on one side of the arc screen plate 11 on the inner wall of the shell 10. A connecting inclined plate 16 is provided between the first discharge port 17 and the arc screen plate 11. A crushing component is provided on one side of the first discharge port 17 on the outer wall of the shell 10. A secondary screening component is provided below the arc screen plate 11 inside the shell 10. The discharge end of the crushing component is connected to the secondary screening component.

[0019] A first motor is installed on one side of the rotating roller 12 on the outer wall of the housing 10. The output end of the first motor passes through the side wall of the housing 10 and is fixedly connected to one end of the rotating roller 12. The first motor is an ordinary asynchronous motor, which can drive the rotating roller 12 and the flipping plate 13 and other components to rotate, thereby turning over the porous brick raw material inside the arc-shaped screen plate 11. During the turning process, through the setting of multiple filter grooves 14, the large particles of porous brick raw material inside the arc-shaped screen plate 11 can be filtered and pushed to one side of the arc-shaped screen plate 11. Under the inclined guiding action of the connecting inclined plate 16, the large particles of porous brick raw material flow into the crushing component for crushing.

[0020] Furthermore, such as Figure 4As shown, the crushing assembly includes a crushing box 18 disposed on the outer wall of the housing 10. Two meshing crushing rollers 19 are rotatably disposed inside the crushing box 18. A first guide plate 20 is disposed on one side of the inner wall of the crushing box 18 on each crushing roller 19. The first guide plate 20 guides the raw material entering the crushing box 18, preventing raw material particles from getting stuck between the crushing rollers 19 and the side wall of the crushing box 18. The input port of the crushing box 18 is connected to the first discharge port 17, and the discharge port of the crushing box 18 is located at the outer wall of the housing 10. A second discharge port 21 is provided on the side wall of the crushing roller 19. A second motor is provided on one side of each crushing roller 19 on the outer side wall of the crushing box 18. The output end of the second motor passes through the side wall of the crushing box 18 and is fixedly connected to one side of the crushing roller 19. The second motor is an ordinary asynchronous motor. The output end of the second motor drives the crushing roller 19 to rotate, thereby crushing the large particles of raw material that enter the crushing roller 19. The crushed raw material flows through the lower port of the crushing box 18 and the second discharge port 21 to the interior of the secondary screening assembly for secondary screening.

[0021] Furthermore, such as Figure 4 As shown, the secondary screening assembly includes a rotating groove 22 disposed on the inner wall of the housing 10. A guide plate 23 is inclinedly disposed on one side of the rotating groove 22. One end of the guide plate 23 is rotatably connected to the rotating groove 22. A third discharge port 24 is disposed on one side of the guide plate 23 on the inner wall of the housing 10. The other end of the guide plate 23 is slidably connected to the third discharge port 24. A plurality of screen holes 26 are disposed on the upper end face of the guide plate 23. A plurality of elastic telescopic rods 25 are rotatably connected between the guide plate 23 and the inner bottom surface of the third discharge port 24. A vibrator 38 is disposed on the lower end face of the guide plate 23. A separation membrane 36 is disposed on one side of the plurality of elastic telescopic rods 25 between the guide plate 23 and the housing 10. The separation membrane 36 is made of elastic sealing material. The separation membrane 36 is designed to form a resistance to the elastic telescopic rods 26. The shielding of the elastic telescopic rod 25 and the vibrator 38 prevents the elastic telescopic rod 25 and the vibrator 38 from being contaminated by the dust from the screen material below the guide plate 23, ensuring the normal operation of the elastic telescopic rod 25 and the vibrator 38 and improving their service life. The raw material screened by the arc-shaped screen plate 11 falls through its screen holes onto the inclined end face of the guide plate 23, and the raw material after being crushed by the two crushing rollers 19 flows through the second discharge port 21 onto the inclined end face of the guide plate 23. Under the inclined setting of the guide plate 23 and the gravity of the raw material itself, it flows downward. Combined with the elastic tension of the elastic telescopic rod 25 and the vibration generated by the vibrator 38, the guide plate 23 screens the porous brick raw material on its end face. The raw material whose particle size still does not meet the requirements is discharged into the device through the third discharge port 24 for other uses.

[0022] Furthermore, such as Figure 3 and Figure 7As shown, baffles 27 are provided between multiple screen holes 26 and on the inclined end face of the guide plate 23. The upper end face of the baffles 27 is arc-shaped. Together with the inclined end face of the guide plate 23, they form stepped baffles between multiple rows of screen holes 26, which restricts the downward speed of the porous brick material on the inclined end face of the guide plate 23, thereby increasing the screening time of the porous brick material on the inclined end face of the guide plate 23 and thus increasing the screening quality of the porous brick material.

[0023] Furthermore, such as Figure 4 As shown, a second guide plate 28 is provided above the connecting inclined plate 16 on the side wall of the housing 10. The second guide plate 28 is provided to guide the raw material entering the arc screen plate 11 from the upper port of the housing 10, preventing the raw material from falling onto the inclined end face of the connecting inclined plate 16 and being directly crushed when entering the housing 10. This ensures that the porous brick raw material entering the housing 10 is screened for the first time by components such as the arc screen plate 11.

[0024] Furthermore, such as Figure 4 , Figure 5 and Figure 6 As shown, each of the multiple filter tanks 14 has a squeezing roller 29 rotatably mounted inside the tilting plate 13 on one side. Each squeezing roller 29 has multiple protrusions 30 on its outer surface. During the process of the tilting plate 13 rotating with the rotating roller 12 to stir and screen the porous brick material inside the arc-shaped screen plate 11, the squeezing rollers 29 and protrusions 30 also rotate with the tilting plate 13 and rotate themselves when in contact with the raw material particles, further stirring and screening the material. The protrusions 30 also press and engage with the screen holes on the inner arc surface of the arc-shaped screen plate 11, pressing down on the raw material inside the screen holes to prevent blockage. A coil spring 3 is installed between each squeezing roller 29 and the tilting plate 13 at both ends. 9. Each coil spring 39 is fixedly provided with a protective shell 40 on the inner side wall of the flipping plate 13. One end of each coil spring 39 is fixedly connected to the inner circular surface of its adjacent protective shell 40. The other end of each protrusion 30 is fixedly connected to the outer circular surface of one end of its adjacent extrusion roller 29. When the extrusion roller 29 rotates with the flipping plate 13, its own rotation will cause the coil spring 39 to be elastically coiled. Under the elastic tension of the coil spring 39, it will cause the extrusion roller 29 to rotate in the opposite direction. This will cause the extrusion roller 29 to drive the protrusion 30 to swing back and forth inside the arc screen plate 11. This makes the extrusion roller 29 and the protrusion 30 more effective in assisting the screening of raw materials inside the arc screen plate 11 and improves the screening efficiency. Example 2:

[0025] Based on Example 1, further examples are made, such as... Figure 4As shown, a third guide plate 37 is provided on the inner wall of the housing 10 above the guide plate 23. The arrangement of the third guide plate 37 forms a pair, which guides the porous brick raw material initially screened by components such as the arc-shaped screen plate 11, causing it to flow to the upper end of the inclined end face of the guide plate 23, thereby increasing the screening time and screening quality of the porous brick raw material on the upper end face of the guide plate 23.

[0026] Finally, it should be noted that the high-efficiency screening device for porous brick processing of this utility model needs to protect the various mechanical structures and related motion logic in this solution. Therefore, it does not elaborate on the various sensors, detectors and driving components required for the actual operation of the various mechanical structures. However, for those skilled in the art, various control systems and electrical connection methods, including various electrical components and driving components, can be completed using conventional technical means. As long as the beneficial effects or the specific actions during the above work can be achieved, they can be implemented. This solution does not impose too many restrictions.

[0027] Furthermore, the motor, exhaust fan, elastic telescopic rod, vibrator, coil spring, etc. in the high-efficiency screening device for porous brick processing in this utility model are all purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.
