Description

Technical Field

[0001] This utility model relates to the field of thermal insulation brick production technology, specifically to a raw material rotary screen for a thermal insulation brick production line. Background Technology

[0002] Rotary screens, also known as drum screens, cylindrical screens, or trommel screens, are a type of efficient and practical screening equipment widely used in various industries. For example, in the production and processing of insulation bricks for the construction industry, if the raw materials contain excessively large particles (such as uncrushed ore, hard clay, etc.), it will lead to uneven internal structure of the bricks, making them prone to cracking and deformation during firing. Therefore, rotary screens are used to screen the raw materials.

[0003] A utility model patent with publication number CN222057977U discloses a drum screen, including a drum screen body and a conveying assembly. The conveying assembly includes a working frame, two guide rails, two rolling rollers, an electric conveyor belt, a hopper, a connecting pipe, hollow columns, bearing seats, a rotating shaft, and a fixed seat. The other end of the connecting pipe is connected to the hopper. The rotating shaft is fixedly connected to the drum screen body, and the fixed seat is fixedly connected to the working frame. The rotating shaft and the fixed seat are rotatably connected. When the electric conveyor belt is started, fly ash is moved into the hopper, and then discharged into the drum screen body through the connecting pipe. Then, the drum screen body is rotated, causing the hollow columns to... The rotary screen rotates within corresponding bearing seats and fixed seats to screen fly ash. This method avoids manual feeding by workers, effectively reducing worker fatigue and improving the efficiency and quality of fly ash screening for subsequent processing. However, this rotary screen lacks a component for cleaning the screen mesh, leading to material blockage during screening and affecting screening efficiency. Therefore, we propose a rotary screen for insulation brick production lines to solve this problem. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 Figure 5 and Figure 6As shown in the figure, an embodiment of the present invention provides a rotary screen for raw materials in a thermal insulation brick production line, comprising an outer cylinder 1, a dust suction pipe 7 fixedly connected to the outer cylinder 1, and a connecting pipe 8 fixedly connected to the surface of the dust suction pipe 7, which facilitates the collection and treatment of dust generated during raw material screening, preventing it from spreading and polluting the environment. In use, simply fix the connecting pipe 8 to the inlet end of the dust suction equipment, and the dust generated inside the outer cylinder 1 can be collected. A cylindrical screen 2 is rotatably connected inside the outer cylinder 1, and a drive mechanism is provided on the outer wall of the outer cylinder 1 for driving the cylindrical screen 2 to rotate. The driving mechanism 3 includes a feed cylinder 4 fixed on one side of the outer cylinder 1, one end of the feed cylinder 4 being rotatably connected to the cylindrical screen 2, and an air blowing assembly 5 being provided inside the outer cylinder 1; the driving mechanism 3 includes a bracket 31 fixed on the surface of the outer cylinder 1, two drive shafts 32 being rotatably connected to the bracket 31 via bearings, a dual-shaft motor 33 fixed on the outer wall of the outer cylinder 1, one end of each drive shaft 32 being fixedly connected to the output end of the dual-shaft motor 33, gears 34 being fixed on the surface of each drive shaft 32, and two toothed rings 35 being fixed on the surface of the cylindrical screen 2, the toothed rings 35 being meshed with the corresponding gears 34 respectively;The air blowing assembly 5 includes two air blowing pipes 51 fixed inside the outer cylinder 1. One end of each air blowing pipe 51 extends through the outer cylinder 1 to its outside and is connected to a fixed U-shaped pipe 52. An air blowing ring 53 is fixed inside the feed cylinder 4. The inlet pipe of the air blowing ring 53 extends through the feed cylinder 4 to its outside and is connected to a fixed heating cylinder 54. Two arc-shaped heating plates 55 are fixed inside the heating cylinder 54. The two fixed arc-shaped heating plates 55 are symmetrically arranged, but one is not shown in the figure. A feed valve is provided on one side of the outer cylinder 1. The air bend 10 has one end connected and fixed to the U-shaped pipe 52, and the other end connected and fixed to the heating cylinder 54. A connecting pipe 2 11 is fixedly connected to the air bend 10. The combination of the air bend 10 and the connecting pipe 2 11 facilitates the blowing heating operation of the raw materials fed into the feed cylinder 4 and the air blowing cleaning operation of the cylindrical screen 2. In use, simply connect and fix the connecting pipe 2 11 to the compressed air conveying pipeline. This is used in the raw material rotary screen process of this thermal insulation brick production line. First, the raw material for the insulation bricks to be screened is fed into the feed cylinder 4. Then, the material enters the cylindrical screen 2 through the feed cylinder 4. The dual-shaft motor 33 is started, and its output drives two drive shafts 32 to rotate synchronously. The gears 34 on the surface of the drive shafts 32 rotate accordingly. Since the gears 34 mesh with the toothed rings 35 on the surface of the cylindrical screen 2, the cylindrical screen 2 can be driven to rotate within the outer cylinder 1. Then, raw material particles that meet the particle size requirements will fall through the screen holes of the cylindrical screen 2 into the bottom of the outer cylinder 1 and be discharged through the discharge hopper. Larger particles that do not meet the requirements move to their end and are discharged under the rotation of the cylindrical screen 2. Secondly, during the screening process, compressed air is connected through connecting pipe 2 11. The compressed air is divided into two paths through the air delivery bend 10: one path enters the U-shaped pipe 52 and then splits into two air blowing pipes 51. The air blowing pipes 51 blow air onto the surface of the cylindrical screen 2 inside the outer cylinder 1, thereby using high-pressure airflow to remove raw material particles clogging the screen holes of the cylindrical screen 2, ensuring screening efficiency; the other path of air enters the heating cylinder 54, where it is heated by two arc-shaped heating plates 55. The heated airflow then enters the air blowing ring 53 inside the feed cylinder 4 through a pipe and is blown out, thus drying the raw material entering the feed cylinder 4 and reducing the adhesion between the damp raw material and the cylindrical screen 2.

[0027] like Figure 3 and Figure 5As shown, in some embodiments, the feed cylinder 4 is equipped with a dispersing component 6 for processing the incoming agglomerated raw materials. The dispersing component 6 includes a support base 61 fixed inside the feed cylinder 4. The top of the support base 61 is rotatably connected to a rotating shaft 62 via a bearing. A dispersing plate 63 is fixed to the top of the rotating shaft 62. An annular groove 65 is formed on the top of the support base 61. Four arc-shaped plates 66, which are adapted to the annular groove 65, are fixed to the bottom of the dispersing plate 63. These plates provide guidance and support for the dispersing plate 63, making it more stable during rotation. The four arc-shaped plates 66 are fixed in a circumferential array. The diagram does not show the entire structure. A crushing frame 64, fixed inside the feed cylinder 4, is located on the outer side of the dispersing plate 63. A drive motor 67 is fixed on the support base 61. The drive motor 67 is a high-temperature resistant and waterproof motor, thus preventing material from affecting its normal operation when installed inside the feed cylinder 4. The output end of the drive motor 67 is fixedly connected to the bottom end of the rotating shaft 62. During use, after the drive motor 67 starts, its output end drives the rotating shaft 62 to rotate on the support base 61 via bearings. The dispersing plate 63 at the top of the rotating shaft 62 rotates along with it, allowing material to enter the feed cylinder 4. The raw materials (including agglomerated materials) will first come into contact with the rotating dispersing plate 63. The centrifugal force and impact force generated by the rotation of the dispersing plate 63 can throw the agglomerated raw materials out in all directions. Then the thrown materials will hit the crushing frame 64 fixed in the feed cylinder 4. The collision between the two will break the agglomerated materials, thereby dispersing the materials more evenly. This will enable the dispersing operation of the input materials. Since the agglomerated raw materials are broken into small particles after being processed by the dispersing component 6, the contact area with the hot airflow blown out by the air blowing ring 53 can be increased, thereby improving the drying efficiency.

[0028] like Figure 1 As shown, in some embodiments, the feed cylinder 4 is fixed with a guide bucket 9. The inlet of the guide bucket 9 is funnel-shaped. By setting the guide bucket 9, the inlet area of ​​the feed cylinder 4 is increased, which facilitates the feeding operation. In addition, with the cooperation of the guide bucket 9, the input raw materials can fall accurately onto the dispersing plate 63 for dispersion.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
