Description

Technical Field

[0001] The invention belongs to the technical field of building gypsum production, and in particular relates to a semi-dry intelligent feeding system for gypsum strip boards. Background Art

[0002] Gypsum building materials are currently mostly manufactured by the casting method, and the water-to-cement ratio is relatively large. The water required for the reaction of hemihydrate gypsum with water to form dihydrate gypsum is only 18% of the total weight of the hemihydrate gypsum, while the water-to-cement ratio of the casting method is currently above 40%, which results in a large amount of free water and attached water in the newly made casting gypsum building materials, which requires a long time of drying and drying. The semi-dry method has a water-to-cement ratio of less than 30%, which reduces the drying and drying time and the cost of using the yard. The free water and attached water quickly reach an absolutely dry state after medium-temperature drying and directly enter the sales link; it reduces carbon emissions and saves related costs. It is currently a more commonly used production method. However, in the prior art, the output of phosphogypsum is huge, and the product quality of phosphogypsum is different from that of desulfurized gypsum. When phosphogypsum is used to produce gypsum laths, the quality of the gypsum laths obtained between different batches and even within the same batch varies greatly due to the difference in quality. In the production process, the raw material ratio needs to be adjusted during the feeding process so that the quality of the obtained gypsum laths is uniform. However, in the prior art, the raw materials are mostly matched and adjusted manually before entering production, which greatly affects the production efficiency. Summary of the invention

[0003] In order to solve the problems in the prior art, the present invention provides a semi-dry intelligent feeding system for gypsum strips. By intelligently transforming the feeding system to form a fully intelligent production line, the production efficiency of phosphogypsum strips is greatly improved, and the obtained gypsum strips are of uniform quality and meet product requirements.

[0035] In order to ensure the premixing effect, save premixing time and reduce production costs, the premixing time in the first premixing barrel is 5 minutes, and the premixing time in the second premixing barrel is 1 minute.

[0036] The stirring time of the main barrel is 16 minutes, and the passing time of the horizontal auger spiral is 3 minutes.

[0037] The first consistency sensor 101 detects the consistency of the material in the main material mixing bin 103 at the 6th minute and the 11th minute after the main material barrel starts feeding, and compares it with the preset value.

[0046] Example

[0047] The materials were configured according to the material formula in Table 1, and the material setting time of the material formula was measured to be 28 minutes for initial setting and 40 minutes for final setting. Gypsum and recycled fiber were respectively put into the first premixing barrel for premixing for 5 minutes, polycarboxylic acid, defoaming agent, and citric acid retarder were put into the second premixing barrel for premixing for 1 minute, and then the premixed materials in the first premixing barrel, the premixed materials in the second premixing barrel, and deionized water were respectively put into the weighing chamber from the first feeding port 106, the second feeding port 105, and the third feeding port 104, and after reaching the preset mass of the control system, they were put into the main material mixing bin 103 for mixing.

[0048] Table 1 Material ratio

[0049]

[0050] The time for the materials to pass through each production device is as follows: 16 minutes for the main material mixing bin 103 to mix, 5 minutes for the main material mixing bin 103 to empty; 3 minutes for the horizontal auger; 3 minutes for the vertical feeding device; 1 minute for the extruder. It can be seen that from the start of material premixing, it takes 28 minutes for the materials to reach the outlet of the extruder 4, and 33 minutes for the materials to empty and reach the outlet of the extruder 4.

[0051] During the production of gypsum strips, the first consistency sensor 101 and the second consistency sensor 204 detect the material consistency in real time. Suppose the system preset consistency is S 0 , real-time detection consistency is S 1 ,

[0052] When the first consistency sensor 101 detects the consistency value S 1 Higher than the preset value S 0 When the deionized water is added from the third feeding port 104, the speed of the stirring motor 112 in the main barrel is increased. The amount of deionized water to be added is:

[0053] (S 1 -S 0 ) / S 0 *Original water consumption*0.5%

[0054] When the first consistency sensor 101 detects the consistency value S 1 Below the preset value S 0 When gypsum is added from the first feeding port 106, the speed of the stirring motor 112 in the main barrel is increased. The amount of gypsum to be added is:

[0055] (S 0 -S 1 ) / S 0 *Original gypsum dosage*0.1%

[0056] When the consistency value S detected by the second consistency sensor 204 is1 Higher than the preset value S 0 When the water reducing agent is added from the water reducing agent feeding port 206, the speed of the horizontal auger motor 202 is increased, and the speed of the motor in the vertical feeding device is reduced. The amount of water reducing agent to be added is:

[0057] (S 1 -S 0 ) / S 0 *Original amount of water reducing agent*0.1‰

[0058] When the consistency value S detected by the second consistency sensor 204 is 1 Below the preset value S 0 When the gypsum is added from the gypsum feeding port 205, the speed of the horizontal auger motor 202 is increased, and the speed of the motor in the vertical feeding device is reduced. The amount of gypsum to be added is:

[0059] (S 0 -S 1 ) / S 0 *Original gypsum dosage*5‰

[0060] Table 2 shows the semi-dry consistency value of the gypsum strip board of this embodiment, which refers to the consistency value of the material after the time corresponding to the time elapsed from the start of premixing. The preset value of the consistency system is set according to the corresponding data in Table 2. The time when the material of this embodiment begins to be discharged from the extruder outlet is 28 minutes, and the consistency is 80mm at this time; the time when the material is emptied and finally discharged from the extruder outlet is 33 minutes, and the consistency is 65mm. It can be seen that the consistency of the material after extrusion from the extruder is between 65 and 80mm, and the time is consistent with the time period when the material enters the initial setting but has not yet been final set. The material of this embodiment meets the most suitable plastic consistency range of gypsum of 60 to 80mm.
