Description

Technical Field

[0001] The present invention relates to the technical field of the preparation of fireproof plates for container houses, and particularly relates to a preparation device and a preparation method for fireproof plates for container houses. Background Art

[0002] In the modern construction industry, container houses are increasingly widely used in aspects such as temporary residence, office, and the construction of various emergency sites due to their advantages of convenience, mobility, and rapid erection. The safety performance of container houses is of crucial importance, and among them, the fireproof performance is one of the key indicators for measuring the quality of container houses. As a commonly used and favored fireproof plate for container houses, rock wool boards have excellent fireproof, heat-insulating, sound-absorbing, and other properties. Their main raw materials are ores such as basalt and dolomite, and they are made through a series of complex processes.

[0003] In the traditional preparation process of rock wool boards, there are many problems. In the raw material processing, the preliminary processing of ores such as basalt and dolomite is not precise enough. After the crusher performs coarse crushing, in the traditional method, when further grinding, it is difficult to grind the raw materials according to suitable grinding parameters, that is, it is impossible to adaptively adjust the rotation speed of the device during grinding according to the size of the raw material particle size. Considering the issues of energy conservation and grinding uniformity, the device should be able to adjust a suitable rotation speed according to the size of the raw material particle size. At the same time, the existing technology lacks an efficient screening measure for the raw materials that have completed grinding. Since the device cannot ensure that the raw materials can be completely ground into suitable particle sizes during grinding, after the raw materials are completed, the ground raw materials should be screened and classified. Raw materials with different levels of particle sizes have different subsequent processing methods, and only through screening and classification can the operation process be simplified and the efficiency of plate preparation be improved.

[0013] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art: 1. Through the provided adaptive judgment component, the present invention can adaptively control the operating state of the device according to the change in weight caused by the particle size of the raw material. The volume of the storage bin is fixed. When the storage bin is filled with raw materials, the raw materials with larger particle size have larger gaps between particles and occupy relatively less effective space, resulting in a relatively lighter overall weight. While the raw materials with smaller particle size are closely packed between particles, occupy a large effective space, and have a heavier overall weight. Based on this characteristic, when different particle size raw materials are loaded into the storage bin, the weight change will drive the storage bin to move up and down, thereby causing the connecting plate and the conductive ring to slide on the variable resistance rod, changing the circuit resistance, and controlling and adjusting the output power of the first motor through the change in circuit resistance, so as to achieve adaptive control of the device operating state.

[0014] 2. Through the provided driving and preparation component, the present invention can provide strong and stable power for the drum. Using the transmission method of the first motor with the first gear and the second gear ensures that the material can be efficiently ground in the drum. The stable rotation enables the material to receive uniform force in the drum, avoiding the situation of excessive or insufficient local grinding, thereby ensuring uniform particle size of the raw material and laying a good foundation for subsequent processes.

[0015] 3. Through the provided filtering component, while achieving efficient filtering of the material, it can also classify and collect according to the particle size difference of the material. The second motor drives the filter cylinder to rotate, and at the same time, the hemisphere at the bottom of the filter cylinder interacts with the abutting column on the inner bottom surface of the collection bucket, causing the filter cylinder to vibrate up and down. This vibration greatly improves the filtering efficiency, avoids clogging of the filter holes, thereby reducing the workload of subsequent manual screening and improving the efficiency of the entire production process.

[0016] 4. Through the grading component provided in the present invention, automatic grading of materials can be achieved. The through slots on the side wall of the filter cylinder, the arc-shaped cover plate, and the third spring constitute an automatic grading structure. By changing the rotation speed of the second motor, the centrifugal force received by the arc-shaped cover plate is changed, and then the opening and closing degree of the arc-shaped cover plate is controlled. By controlling the opening and closing state of the arc-shaped cover plate, materials with different particle sizes are screened out. Since different particle-sized raw materials have different subsequent processing methods, screening and grading them in advance is beneficial to improving the overall processing efficiency and simplifying the processing process. At the same time, the screened materials can also reflect the grinding effect of the preparation device. If there are too many coarse particles after grading, it indicates that the grinding is not sufficient, and the grinding time and rotation speed of the preparation device can be adjusted to optimize the grinding process and improve production efficiency.

[0022] Embodiment: Refer to Figures 1 to 9, a preparation device for a fireproof board of a container house. The fireproof board of the container house includes a rock wool board 1. The rock wool board 1 includes a rock wool core insulation layer 11. The upper surface and the bottom surface of the rock wool core insulation layer 11 are both covered with a facing protective layer 12. A moisture-proof layer 13 is filled between the two facing protective layers 12 and the rock wool core insulation layer 11. The rock wool core insulation layer 11, the facing protective layer 12 and the moisture-proof layer 13 are bonded by an adhesive. The facing protective layer 12 can use metal plates such as galvanized steel plates, aluminum plates, color steel plates, and fiber fabrics such as fiberglass cloth and non-woven fabrics. The adhesive can use silicone resin, phenolic resin, etc. The moisture-proof layer 13 is located between the rock wool core insulation layer 11 and the facing protective layer 12 and can be made of materials such as moisture-proof paper and aluminum foil. The fireproof board of the container house is prepared by a board preparation device. The board preparation device includes a roller 2. Two support seats 21 are rotatably sleeved outside the roller 2. A support frame 22 is arranged on the side of the roller 2. A feed pipe 23 is rotatably communicated with the side wall of the roller 2. A first discharge pipe 24 is communicated with the lower end surface of the roller 2. A filter plate 25 is fixedly arranged in the first discharge pipe 24. The output end of the first discharge pipe 24 is sleeved with a sealing cover plate. A preparation mechanism is arranged between the roller 2 and the support frame 22. The preparation mechanism includes an adaptive judgment component 3, a driving preparation component 4, a filtering component 5 and a grading component 6; The adaptive judgment component 3 includes a storage cylinder 31 arranged above the support frame 22. A second discharge pipe 32 is communicated with the bottom surface of the storage cylinder 31. The second discharge pipe 32 is slidably sleeved on the input end of the feed pipe 23. Two first guide rods 33 are fixedly connected to the bottom surface of the storage cylinder 31. Both of the two first guide rods 33 penetrate and are slidably connected to the inner top surface of the support frame 22. Two first springs 34 are fixedly connected between the bottom surface of the storage cylinder 31 and the upper surface of the support frame 22. A baffle 35 is arranged in the storage cylinder 31. The baffle 35 penetrates and is slidably connected to the side wall of the storage cylinder 31. The bottom ends of the two first guide rods 33 are fixedly connected with a connecting plate 36. A variable resistance rod 37 is fixedly installed on the inner wall of the support frame 22. A conductive ring 38 is slidably sleeved on the variable resistance rod 37. A control rod 39 is fixedly connected to the side wall of the conductive ring 38. The bottom surface of the connecting plate 36 is fixedly connected with a pressing rod 310. The bottom surface of the pressing rod 310 is in contact with the upper surface of the control rod 39. The two first springs 34 are respectively sleeved on the two first guide rods 33. The bottom surface of the baffle 35 is in fit with the inner bottom surface of the storage cylinder 31. A rough layer is arranged on the inner wall of the conductive ring 38. By arranging the rough layer, the friction force between the inner wall of the conductive ring 38 and the surface of the variable resistance rod 37 is increased, so that the conductive ring 38 has a certain resistance when sliding on the variable resistance rod 37 subsequently, and thus can stay at any position. After each grinding, the conductive ring 38 can be dialed back to the initial position at the top; Specifically, a density detection module is added to the storage cylinder 31. Before the raw materials enter the storage cylinder 31, the density of the raw materials is detected first. A density detection device based on the principle of ray absorption can be used. Raw materials with different densities have different absorption degrees of rays, and the density of the raw materials can be calculated by detecting the change in ray intensity; After obtaining the raw material density data, it is combined with the preset particle size-weight model. Taking basalt and dolomite as examples, assuming that the common density range of basalt is (x1 - x2) and the common density range of dolomite is (y1 - y2), according to different density values, the relationship between particle size and weight is corrected. When the detected raw material density is within the basalt density range, it is calculated according to the particle size-weight correction model of basalt to determine the accurate relationship between the weight change of the storage cylinder 31 and the raw material particle size, and then the power of the first motor 42 is adjusted more precisely to make the rotation speed of the drum 2 match the raw material particle size; The driving preparation assembly 4 includes an L-shaped plate 41 fixedly connected to the side wall of the support base 21. The upper surface of the L-shaped plate 41 is fixedly connected with a first motor 42 through a bracket. The output end of the first motor 42 is fixedly connected with a first rotating shaft 43. The first rotating shaft 43 passes through and is rotatably connected to the side wall of the L-shaped plate 41 through a bearing. One end of the first rotating shaft 43 away from the first motor 42 is fixedly connected with a first gear 44. A second gear 45 is fixedly connected to the circumference of the drum 2. The first gear 44 meshes with the second gear 45. The conductive ring 38 is electrically connected to the first motor 42. The circuit formed by the conductive ring 38, the variable resistance rod 37 and the first motor 42 is electrically connected to an external power supply, and the output power of the first motor 42 is controlled by the change in the resistance in the circuit; The filtering assembly 5 includes a collection barrel 51 fixedly connected between two support bases 21. The inside of the collection barrel 51 is divided into a first collection area 52, a second collection area 53 and a third collection area 54 from the inside to the outside in sequence. The bottom surface of the collection barrel 51 is fixedly connected with a second motor 55 through a bracket. The output end of the second motor 55 is fixedly connected with a second rotating shaft 56. The second rotating shaft 56 passes through and is rotatably connected to the inner bottom surface of the collection barrel 51 through a bearing. The top end of the second rotating shaft 56 is fixedly connected with a first circular plate 57. A second circular plate 58 is arranged above the first circular plate 57. The bottom surface of the second circular plate 58 is fixedly connected with a plurality of second guide rods 59. The plurality of second guide rods 59 all pass through and are slidably connected to the bottom surface of the first circular plate 57. A plurality of second springs 510 are fixedly connected between the first circular plate 57 and the second circular plate 58. The upper surface of the second circular plate 58 is fixedly connected with a filter cylinder 511. A plurality of filter holes 512 are opened on the bottom surface of the filter cylinder 511. An abutting column 513 is fixedly connected to the inner bottom surface of the collection barrel 51. The top end of the abutting column 513 is arranged in a hemispherical shape. The plurality of second springs 510 are respectively sleeved on the plurality of second guide rods 59; The grading component 6 includes a plurality of through grooves 61 formed in the side wall of the filter cylinder 511. A plurality of arc-shaped covers 62 are hinged to the circumferential side wall of the filter cylinder 511. The plurality of arc-shaped covers 62 respectively cover the sides of the plurality of through grooves 61. A third spring 63 is fixedly connected between the inner top surface of each of the plurality of through grooves 61 and the side wall of the arc-shaped cover 62. The plurality of arc-shaped covers 62 and the through grooves 61 are all arranged equidistantly around the second rotating shaft 56. Specifically, to improve the accuracy of the grading component 6, a sensor and a feedback control system can be introduced into the grading component 6. An angle sensor is installed on the arc-shaped cover 62 to monitor the opening and closing angle of the arc-shaped cover 62 in real time and feed the angle data back to the control system. At the same time, a particle size detection sensor is installed near the through groove 61 to detect the particle size of the material passing through the through groove 61. The control system compares the material particle size data fed back by the particle size detection sensor with the preset particle size grading standard. If the actual particle size of the passing material does not meet the preset standard, the control system automatically adjusts the rotation speed of the second motor 55. When it is detected that the particle size of the material passing through the through groove 61 is too large, it means that the opening degree of the arc-shaped cover 62 is too large. The control system reduces the rotation speed of the second motor 55 to reduce the centrifugal force received by the arc-shaped cover 62 and make its opening and closing angle decrease until the particle size of the passing material meets the preset standard. In this way, through real-time monitoring by the sensor and feedback control, more accurate grading of the material can be achieved.

[0023] The working principle of the present invention is as follows: Before grinding the raw materials, several grinding spheres are added into the drum 2. Similar to the working principle of a ball mill, when the device is working, the drum 2 rotates, causing collisions and frictions among multiple grinding spheres, thereby realizing the grinding of the internal raw materials. First, the crushed basalt, dolomite and other ore raw materials are added into the storage cylinder 31 until the storage cylinder 31 is full. At this time, the adaptive judgment component 3 works and can adjust the operating power of the first motor 42 according to the weight change caused by the particle size of the raw materials. When the storage cylinder 31 is filled with raw materials with large particle sizes, due to the same density of the raw materials, the gaps between the large particles are large, occupying a small effective space and having a light overall weight. The storage cylinder 31 moves downward a relatively small distance under pressure, driving the connecting plate 36 and the pressure rod 310 to move a relatively small distance. The pressure rod 310 drives the control rod 39 and the conductive ring 38 in contact with it to slide a relatively small distance on the variable resistance rod 37, and the resistance of the corresponding circuit is also relatively small. Therefore, the working power of the first motor 42 is increased, the rotation speed of the drum 2 is accelerated to adapt to the raw materials with large particle sizes, and the grinding effect is enhanced. If the raw materials with small particle sizes are loaded, due to the same density, their particles are closely packed and the weight will be relatively heavy. The storage cylinder 31 moves downward a relatively large distance. At this time, the resistance of the corresponding circuit is relatively large, which will reduce the power of the first motor 42 and slow down the rotation speed of the drum 2. While avoiding over-grinding, it is also conducive to saving energy. After completing the above work, by moving the baffle 35, the raw materials can enter the drum 2 through the feed pipe 23. When the raw materials enter the drum 2, the storage cylinder 31 loses pressure and is reset under the action of two first springs 34. The two first guide rods 33 drive the connecting plate 36 and the pressure rod 310 to move upward. Affected by the frictional force, the conductive ring 38 stays at this position. At this time, when the first motor 42 works, it drives the first rotating shaft 43 and the first gear 44 to rotate, and drives the second gear 45 and the drum 2 to rotate through meshing transmission. The rotation of the drum 2 causes the internal grinding spheres to collide and rub, realizing the efficient grinding of the raw materials. The power of the first motor 42 can control the rotation speed of the drum 2. When the rotation speed of the drum 2 changes, the motion state of the grinding spheres will change. Larger particle size raw materials require greater impact force and grinding force to be effectively broken and ground. A higher rotation speed can enable the grinding spheres to obtain a greater lifting height and speed, so as to impact and grind the raw materials with greater force, which helps to break the large particle raw materials into smaller particles. Similarly, when the particle size of the raw materials is small, the rotation speed of the drum 2 can be appropriately reduced. If the rotation speed is too high, the impact force of the grinding spheres may be too large, resulting in over-grinding, making the particle size distribution of the product too narrow, and even causing over-crushing phenomenon, increasing energy consumption and production costs. Therefore, by controlling the rotation speed of the drum 2 through the weight change caused by the particle size of the raw materials, the device can automatically adjust the grinding parameters according to the particle size of the raw materials, so as to realize the adaptation to the grinding of raw materials with different particle sizes, which is more in line with the actual use requirements. When replacing the raw materials for grinding later,Just slide the conductive loop 38 upward along the variable resistance rod 37 to reset it by toggling the control rod 39, and then make a judgment again through the adaptive judgment component 3; After the above-mentioned grinding is completed, the ground materials discharged by the roller 2 through the first discharge pipe 24 will enter the collection barrel 51 fixedly connected between the two support seats 21. Then, start the second motor 55, and the second rotating shaft 56 at its output end rotates. The filter cylinder 511 fixedly connected to the upper surface of the second circular plate 58 rotates with the second motor 55. At the same time, the abutting posts 513 fixedly connected to the inner bottom surface of the collection barrel 51 interact with the multiple hemispheres 514 fixedly connected to the bottom surface of the second circular plate 58. When the filter cylinder 511 rotates, the hemispheres 514 collide with the abutting posts 513, causing the filter cylinder 511 to vibrate up and down, accelerating the materials to pass through the multiple filter holes 512 opened on the bottom surface of the filter cylinder 511, realizing efficient filtration. During the rotation of the filter cylinder 511, the internal materials are affected by the centrifugal force. The ground materials with good grinding effect have small particle size and light weight, and are affected by small centrifugal force, and will directly pass through the filter holes 512 to reach the first collection area 52 of the collection barrel 51. While the materials with poor grinding effect have relatively large particle size and relatively large self-weight, and are affected by large centrifugal force, and will reach the edge position inside the collection barrel 51 under the action of the centrifugal force. When the grinding of the materials with good effect is completed, by changing the rotation speed of the second motor 55, the rotation speed of the filter cylinder 511 is adjusted, and then the magnitude of the centrifugal force received by the arc-shaped cover plate 62 is changed. The arc-shaped cover plate 62 overcomes the elastic force of the third spring 63 by the received centrifugal force, causing itself to rotate and open around the hinge point. The greater the rotation speed of the second motor 55, the greater the centrifugal force received by the arc-shaped cover plate 62, and the greater the opening degree. Similarly, when the rotation speed becomes smaller, the centrifugal force becomes smaller, and the opening degree also becomes smaller. By controlling the rotation speed of the second motor 55, the opening and closing degree of the arc-shaped cover plate 62 is controlled, so that the materials within this particle size range can directly fall into the suitable collection area through the through groove 61, thereby realizing different degrees of classified collection, meeting the diverse requirements of subsequent different processing methods for the particle size of the materials, and at the same time, the screened materials can also reflect the grinding effect of the preparation device. If there are too many coarse particles after classification, it means that the grinding is not sufficient, and the grinding time and rotation speed of the preparation device can be adjusted to optimize the grinding process and improve production efficiency.
