Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of batching plants, and particularly relates to a foamed concrete batching plant. Background Technology
[0002] Foamed concrete is currently an ideal material for making wall and roof insulation layers, with advantages such as light weight and low thermal conductivity. Its production process requires cementitious materials, lightweight aggregates, admixtures and water to be fully mixed by a mixing device and then foamed into shape. In the current use of the mixing equipment in the batching plant, it has been found that when lightweight aggregates and cementitious materials are mixed by a separate mixing device, the lightweight aggregates will be suspended in the slurry, resulting in poor homogeneity of the mixture between the slurry and aggregates. In order to meet the requirements of the finished product, the mixing time needs to be extended, resulting in low production efficiency of the batching plant. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a foamed concrete mixing plant that solves the problems of poor mixing effect of the mixing device, suspension of lightweight aggregate in the slurry, and poor homogeneity in the current foamed concrete mixing plant.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0020] 1. The mixing plant of this utility model combines a vertical shaft mixer and a horizontal shaft mixer. The vertical shaft mixer pre-mixes the aggregate into a slurry, and then the slurry and lightweight aggregate are mixed in the horizontal shaft mixer. Compared with traditional mixing plants, this method can avoid the lightweight aggregate from suspending on the surface of the slurry during the mixing process, improve the mixing effect of lightweight aggregate and slurry, and achieve good homogeneity and high mixing efficiency.

[0025] The following is in conjunction with the appendix Figure 1 The specific embodiments of this utility model will be further described in detail below.
[0026] Reference Appendix Figure 1 Overall, this embodiment provides a foamed concrete mixing plant, including a vertical shaft mixer 1 and a horizontal shaft mixer 2 for mixing materials. That is, this mixing plant includes two mixers, a vertical shaft mixer and a horizontal shaft mixer. Utilizing the advantages of the vertical shaft mixer 1 and the horizontal shaft mixer 2 in mixing different materials, different mixing methods are used for different materials, thereby improving the quality of the finished product. It includes at least one raw material hopper 3 for feeding materials to the vertical shaft mixer 1, a metering and feeding device 4 for metering the material discharged from the raw material hopper 3, a temporary storage hopper 5 connected to the discharge port of the vertical shaft mixer 1, a weighing hopper 6 for weighing the material discharged from the temporary storage hopper 5, and the weighing hopper 6 connected to the inlet of the horizontal shaft mixer 2; an external granulation hopper for feeding materials to the horizontal shaft mixer 2, where the material discharged from the external granulation hopper and the material discharged from the weighing hopper 6 are mixed within the horizontal shaft mixer 2; and a control host for controlling the operation of each component.
[0027] In some embodiments, the raw material silo 3 includes a water silo, an admixture silo, a cement silo, and a fly ash silo. That is, in this embodiment, a foamed concrete mixing plant using water, admixtures, cement, and fly ash as raw materials is provided. The water silo, admixture silo, cement silo, and fly ash silo are respectively connected to the vertical shaft mixer 1 through pipelines to meet the requirement that water, admixtures, cement, and fly ash are mixed in the vertical shaft mixer 1. The forced mixing force of the vertical shaft mixer 1 can more quickly prepare the fine powder with water and admixtures into a mixed slurry.
[0028] In some embodiments, the metering and feeding device 4 includes an electromagnetic flow meter installed in the water tank, a feeder installed in the cement tank and fly ash tank, and an electromagnetic flow meter installed in the admixture tank. The electromagnetic flow meter is used to meter the water supply to the vertical shaft mixer 1, the feeder is used to meter the cement and fly ash added to the vertical shaft mixer 1, and the electromagnetic flow meter is used to meter the admixture added to the vertical shaft mixer 1.
[0029] In some embodiments, the electromagnetic flowmeter installed in the water tank, the feeder installed in the cement silo and fly ash silo, and the electromagnetic flowmeter installed in the admixture silo are all controlled by the control host. This satisfies the requirement that the electromagnetic flowmeter and feeder are controlled by the control host to add water, cement, fly ash, and admixtures to the vertical shaft mixer 1 according to the input mixing ratio. This results in a high degree of automation and high production efficiency.
[0030] In some embodiments, the feeder may be selected as a star feeder commonly used in the prior art for transporting powder materials.
[0031] It should be understood that in this embodiment, the pre-mixed slurry from the vertical shaft mixer 1 is discharged into the temporary storage chamber 5. In actual operation, the pre-mixed slurry in the vertical shaft mixer 1 needs to be discharged into the horizontal shaft mixer 2 for final mixing. However, the mixing times of the horizontal shaft mixer 2 and the vertical shaft mixer 1 are not synchronized. There will be instances where the material in the horizontal shaft mixer 2 is not fully mixed after the vertical shaft mixer 1 has finished mixing. At this point, the vertical shaft mixer 1 needs to stop and wait for the material in the horizontal shaft mixer 2. Simultaneously, the material discharged from the vertical shaft mixer 1 cannot be completely discharged. If the material is not discharged into the horizontal shaft mixer 2 at this time... Metering the pre-mixed slurry will result in a large error in the material mixing ratio within the horizontal shaft mixer 2, ultimately affecting the quality of the finished product. Therefore, in this embodiment, by setting up a temporary storage bin 5, it is possible to ensure that the vertical shaft mixer 1 is emptied in a timely manner, thus ensuring the efficiency of pre-mixed slurry preparation. On the other hand, it also facilitates the metering of the pre-mixed slurry discharged into the horizontal shaft mixer 2. That is, in this embodiment, the weighing hopper 6 can detect the weight of the pre-mixed slurry discharged from the temporary storage bin. However, it is not limited to the method of measuring the weight of the pre-mixed slurry. The weighing hopper 6 can also be set to a fixed capacity (unit capacity) method, and the unit capacity can be calculated for metering.
[0032] In some embodiments, a pumping mechanism 7 is further included for conveying the material in the temporary storage bin 5 to the weighing hopper 6. The pumping mechanism 7 is controlled to start and stop by the control host to ensure that the pre-made slurry in the temporary storage bin 5 can be quickly and stably conveyed to the weighing hopper 6, so as to facilitate the metering of the pre-made slurry in the weighing hopper 6.
[0033] In some embodiments, the pumping mechanism 7 may be selected as a diaphragm pump, that is, the two ends of the diaphragm pump are connected to the discharge port of the temporary storage bin 5 and the inlet of the weighing hopper 6 respectively. The diaphragm pump pumps the pre-made slurry into the weighing hopper 6 through the pipeline. The diaphragm pump is a common pumping device for conveying fluid materials in the current technology, and has the advantages of convenient pumping and good wear resistance.
[0034] In some embodiments, a stirring mechanism for stirring materials is installed in the temporary storage chamber 5. That is, a stirring mechanism similar to the commonly used mixing tank is set in the temporary storage chamber 5. The stirring mechanism continuously stirs the pre-made slurry temporarily stored in the temporary storage chamber 5 to prevent precipitation and segregation of the pre-made slurry in the temporary storage chamber 5. In this embodiment, the stirring mechanism may be a frame-type stirring blade, which can stir the area near the bottom and inner wall of the temporary storage chamber 5. This ensures that the slurry entering the temporary storage chamber 5 is prevented from segregating and precipitating by the stirring mechanism, thus maintaining the mixed state of the slurry and ensuring the homogeneity of the slurry entering the horizontal shaft mixer 2.
[0035] It should be understood that the materials stirred in the horizontal shaft mixer 2 are precast slurry and added particles. In this embodiment, the added particles are preferably polystyrene particles. Compared with traditional foamed concrete mixing plants, this mixing plant sets up two mixers to mix the slurry and the slurry and polystyrene particles separately. When the slurry formed by mixing with the selected mix ratio is mixed with the polystyrene particles, the horizontal shaft mixer 2 can more easily press the polystyrene particles into the slurry than the vertical shaft mixer 1, thereby improving the homogeneity of the mixing of polystyrene particles and slurry.
[0036] In some embodiments, the added particles can be added manually, and the added particle chamber is set as a compartment of a certain volume according to the mixing ratio, so as to accurately measure the amount of added particles each time.
[0037] In some embodiments, to improve efficiency, an automatic metering and feeding mechanism for the external particle bin is also provided. The external particle bin is connected to the horizontal shaft mixer via a secondary storage bin (not shown in the attached diagram). The secondary storage bin is pre-set to be a chamber with a fixed unit volume, thereby allowing the control unit to control the external particle bin to discharge material into the secondary storage bin and automatically control the number of times material is added to the horizontal shaft mixer 2 according to the mixing ratio. That is, after the secondary storage bin is full, the control unit controls the opening of the secondary storage bin's material gate to add material to the horizontal shaft mixer 2, and the operation of the external particle bin and the secondary storage bin is cyclical until external particles meeting the mixing ratio are added. The advantage of this arrangement is that sequentially adding external particles facilitates the mixing of the external particles and the slurry. Another embodiment is: the external particle bin and the secondary storage bin... A volumetric scale is installed between the two, specifically at the discharge port of the external granulation bin. In this case, the intermediate storage bin no longer needs to be set to a unit volume size. This allows the volumetric scale to measure the volume of polystyrene granules discharged from the external granulation bin before they are discharged into the intermediate storage bin. Through the intermediate storage bin, it can be ensured that after the horizontal shaft mixer 2 completes its mixing production, the intermediate storage bin has already been pre-controlled by the main control unit to add a new batch of polystyrene granules. At the same time, the temporary storage bin 5 works on the same principle as the intermediate storage bin. This combination ensures that the vertical shaft mixer 1 can continuously circulate and produce slurry. The slurry is stored in the temporary storage bin 5. After the horizontal shaft mixer 2 completes one mixing cycle and discharges the material, slurry is quickly replenished into the horizontal shaft mixer 2, thereby reducing the waiting time of the horizontal shaft mixer 2 and improving the mixing efficiency.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
