Description

Technical Field

[0001] This utility model relates to the field of heavy calcium carbonate production technology, specifically a material mixing device for improving reaction efficiency. Background Technology

[0002] In the traditional process of producing superphosphate by reacting phosphate rock powder with phosphoric acid, the phosphate rock powder and phosphoric acid are added separately to a mixer and thoroughly mixed under stirring to carry out a primary reaction. Then, they enter a formation chamber for a secondary reaction, and finally undergo a tertiary reaction in a curing chamber to obtain a qualified superphosphate product. The key to the primary reaction in the mixer is to achieve a uniform mixing of the phosphate rock powder and phosphoric acid to form a suitable concentration distribution. The critical point here is to avoid uneven mixing, excessive phosphate rock powder, or excessive phosphoric acid in certain areas, as this will prevent subsequent reactions from continuing due to insufficient reactants, ultimately affecting product quality indicators.

[0003] However, in actual production, this process has the following four problems: 1. With the increase in production capacity, the amount of phosphate rock powder added has increased, and the space in the mixer is insufficient. Phosphate rock powder and phosphoric acid cannot be fully mixed to form a suitable concentration distribution. There is a significant local overabundance of phosphate rock powder or phosphoric acid in fresh calcium. This will cause subsequent reactions to be unable to continue due to insufficient reactants. It is necessary to add extra turning and mixing operations and extend the maturation time to ensure product quality, which will significantly reduce the production rate and efficiency; 2. The quality indicators of the same batch of unevenly mixed fresh calcium product vary greatly when used at different times. 1. Even when the granulation and batching stage is lax, the main content may be unqualified, increasing the quality risk of the product; 2. Phosphate rock powder and phosphoric acid are squeezed into the formation chamber before they are fully mixed. During the fall in the formation chamber, they are drawn away by the exhaust duct, resulting in the loss of phosphate rock powder; 3. If the fresh calcium entering the maturation warehouse is not mixed well, it will cause the quality of the same pile of calcium powder to fluctuate. At this time, the crane needs to add extra turning and mixing operations and invest 2-3 people to take samples and analyze at multiple times and in multiple locations. This doubles the workload of the workshop crane operators, sampling personnel and company analysts, increasing the labor intensity and difficulty of the employees.

[0004] According to Chinese Patent Publication No. CN201922155268.3, published on December 5, 2019, a high-efficiency chemical material mixing device is disclosed. The device includes a base plate, a housing, and a motor. A support column is positioned above the base plate, and the housing is positioned above the support column. A discharge hopper is fixedly installed at the lower end of the housing, and a discharge pipe is installed at the bottom of the discharge hopper. A power compartment is located at the upper end of the housing, and a motor is fixedly installed at the lower end of the power compartment. A first bevel gear is installed at the left end of the motor, and the first bevel gear meshes with a second bevel gear and a third bevel gear. A first rotating shaft and a second rotating shaft are fixedly installed at the lower ends of the second and third bevel gears, respectively. In this chemical material mixing device, the second and third stirring blades rotate in the same direction but opposite to the rotation direction of the first stirring blade, causing convection of the chemical material solution inside the housing. Simultaneously, the third stirring blade agitates the mixture in the discharge hopper at the bottom of the housing, enhancing the mixing effect of the chemical materials.

[0005] In actual use, the above-mentioned mixing device can only increase the mixing rate of materials inside the device to a certain extent by setting the stirring blades to rotate in opposite directions. It cannot make the different raw material components inside the device uniformly mixed. At the same time, there are uneven mixing in some areas and excessive raw materials in some places. In addition, the internal mixing space is limited, and the amount of material that can be processed at the same time is limited, so there are defects in its use.

[0026] 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.

[0027] Please see Figure 1-5 This utility model provides an embodiment: a material mixing device for improving reaction efficiency, including a mixer 6, a top cover 8 at the top of the mixer 6, a phosphate rock powder feeding socket 13 fixed on the right side of the top of the top cover 8, and a phosphoric acid feeding socket 14 on the right side of the phosphate rock powder feeding socket 13, the bottom ends of the phosphate rock powder feeding socket 13 and the phosphoric acid feeding socket 14 respectively penetrating the interior of the top cover 8;

[0032] Specifically, such as Figure 1 - Figure 4 As shown, after the phosphate rock powder and phosphoric acid material are mixed inside the mixer 6, the drive motor 21 can be controlled to start and drive the mounting shaft 4 to rotate. The rotation of the mounting shaft 4 can drive the multiple sets of blades 3 on the outside to rotate.

[0034] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, by screwing the mounting bolts 15 into the internal threaded holes 29 at the top of the mixer 6 at both ends of the top of the top cover 8, the top cover 8 can be separated from the top of the mixer 6. After opening the inside of the device, the components can be easily cleaned and maintained.

[0035] The bottom of both ends of the mixer 6 is vertically fixed with support legs 20, and the front end of the support legs 20 is equipped with a controller.

[0036] Working Principle: When using the device, the height of mixer 6 is kept constant, but it is enlarged to twice its original size to increase the mixing space for phosphate rock powder and phosphoric acid. Phosphate rock powder and phosphoric acid, used in the production of heavy calcium carbonate, are introduced into the mixer 6 through phosphate rock powder feeding socket 13 and phosphoric acid feeding socket 14, respectively. Simultaneously, drive motors 10 and 16 can be started, driving agitator 7, agitator 2, and the screw conveyor shaft 17 to rotate. The rotation of the screw conveyor shaft 17 pushes the material added from the right side towards the center. Three sets of vertical stirring rods 18 can flip the pushed material upwards. By adding a set of stirring equipment, a "one tank, two paddles" layout can be formed using agitator 7 and agitator 2 12, increasing the stirring intensity and ensuring thorough mixing of phosphate rock powder and phosphoric acid within the mixer 6. At the same time, the phosphate rock powder feeding socket 13 and the phosphoric acid feeding socket 14 are arranged close together on the same side, reducing the solid content in localized areas, increasing material flowability, and making the mixing more uniform. After the phosphate rock powder and phosphoric acid are mixed inside the mixer 6, the drive motor 21 can be started to drive the mounting shaft 4 to rotate. The rotation of the mounting shaft 4 can simultaneously drive the multiple sets of blades 3 on the outside to rotate. The material inside the mixer 6 can be pushed by the screw conveyor shaft 17 and discharged from the discharge port 5 into the interior of the shell 2. The multiple sets of blades 3 can uniformly and continuously feed the material to the outer formation chamber. After screwing the mounting bolts 15 into the corresponding threaded inner holes 29 at both ends of the top of the top cover 8, the top cover 8 can be separated from the top of the mixer 6.
