The traditional preparation method of calcium aluminate has some problems in efficiency, energy consumption and product quality. Therefore, how to improve the efficiency and reduce energy consumption in the preparation process of calcium aluminate has become a research hotspot in the industry.
[0003] However, the particle size and uniformity of calcium aluminate produced during the preparation process are affected by many factors. For example, the temperature, atmosphere, stirring and other conditions in the furnace will affect the formation and particle size of calcium aluminate. Different preparation processes and equipment will also produce calcium aluminate of different sizes and distributions. When preparing calcium aluminate, calcium aluminate with particles that are too large will reduce the reaction rate and conversion efficiency of calcium aluminate, and the reaction process requires stirring to allow the raw materials to contact more fully for chemical reaction. Therefore, a device is needed to finely screen the raw calcium aluminate and stir the raw materials in the reaction vessel to increase the reaction efficiency.
[0004] In addition, the preparation process of calcium aluminate tends to generate a large amount of heat, and the lack of a heat dissipation device can easily cause damage to the mixing device, posing a safety risk. Utility Model Content

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.
[0031] Example 1
[0032] Reference Figure 1 to Figure 4 , which is the first embodiment of the utility model, provides a screening synchronous stirring mechanism, including a screening assembly 100, including a limit arm 101, a screen plate 102 is clamped in the limit arm 101, and screen holes 102a are evenly opened radially on the screen plate 102. A connecting shaft 103 is fixedly arranged at the center of the screen plate 102; the screening assembly 100 is used to screen the raw material calcium aluminate, and only the calcium aluminate with a particle size that meets the size can pass through the screen plate 102 and enter the next step of the preparation process.
[0033] And, the adjustment component 300 includes a driving shaft 301 and a distance control disk 302, and the connecting shaft 103 is rotatably arranged on the driving shaft 301. The adjustment component 300 is used to link the screening component 100 and the stirring component 200 so that the two can synchronously adjust the speed according to the actual operation needs.
[0034] Further, the driving shaft 301 passes through the limit block 303, and the driving shaft 301 is movably arranged on the limit block 303. That is, the driving shaft 301 can rotate in the limit block 303, and the length of the extension of its two ends can be adjusted.
[0035] The driving shaft 301 is driven by a motor to rotate. Since the driving shaft 301 is connected to the connecting shaft 103, the rotation of the driving shaft 301 can drive the sieve plate 102 to rotate in a circle with the connecting shaft 103 as the center.
[0036] A pair of limiting disks 301a are fixedly provided on the driving shaft 301, and the spacing of the limiting disks 301a is the same as the thickness of the distance control disk 302. The distance control disk 302 is clamped in the middle by the limiting disk 301a. A knob 302a is fixedly provided on one side of the distance control disk 302, and a screw rod 302b is fixedly provided on the other side thereof. A convex block 303a is also provided on the side of the limiting block 303 close to the limiting disk 301a, and a threaded hole matching the specification of the screw rod 302b is provided on the convex block 303a, and the screw rod 302b is threadedly connected with the convex block 303a. By holding the knob 302a and rotating it to rotate the distance control disk 302, the extension length of the screw rod 302b can be adjusted, and finally the distance between the driving shaft 301 and the sieve plate 102 can be controlled.
[0037] In actual operation, when the driving shaft 301 is in the original position, the driving shaft 301 drives the sieve plate 102 to rotate horizontally in the limit arm 101, and the limit arm 101 always maintains a horizontal state. When calcium aluminate raw material is added to the sieve plate 102, the motor is first started to rotate the driving shaft 301, and then the knob 302a is rotated to rotate and lift the screw 302b. At this time, the distance control plate 302 drives the limit plate 301a to lift, and then the driving shaft 301 is lifted. After the driving shaft 301 is lifted, the sieve plate 102 is pulled by the connecting shaft 103. If the sieve plate 102 continues to rotate, it can only compensate for the increased distance by performing circular wave motion. The staff can adjust the rising height of the driving shaft 301 according to the amount of feed. The greater the rising height, the greater the rotation amplitude of the sieve plate 102. While the sieve plate 102 is shaking, calcium aluminate can move in the sieve plate 102 and fall into the reaction solution through the sieve hole 102a.
[0038] Example 2
[0039] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model, and this embodiment also includes a stirring assembly 200, including a driven shaft 201, on which a rotating member 202 is symmetrically sleeved, and the rotating member 202 can rotate in a circle along the driven shaft 201. The rotating member 202 is connected to the limiting arm 101; the stirring assembly 200 is used to stir the screened calcium aluminate and the solution to make them fully react.
[0040] One end of the limit block 303 is connected to the back plate 304, and a position control shaft 305 is also provided on the back plate 304, and the position control shaft 305 is perpendicular to the back plate 304. The function of the position control shaft 305 is to limit the driven shaft 201, and the driven shaft 201 is limited to only the position control shaft 305 as the center of the circle. A through hole 201a is opened in the middle of the driven shaft 201, and the position control shaft 305 passes through the through hole 201a. A stirring shaft 203 is also fixedly provided on the driven shaft 201, and a stirring blade 203a is spirally provided on the stirring shaft 203.
[0041] In actual operation, when the driving shaft 301 is in the original position, the driving shaft 301 drives the sieve plate 102 to rotate horizontally in the limit arm 101, and the limit arm 101 always maintains a horizontal state. When calcium aluminate raw material is added to the sieve plate 102, the motor is first started to rotate the driving shaft 301, and then the knob 302a is rotated to rotate and lift the screw 302b. At this time, the distance control plate 302 drives the limit plate 301a to lift, and then the driving shaft 301 is lifted. After the driving shaft 301 is lifted, the sieve plate 102 is pulled by the connecting shaft 103. If the sieve plate 102 continues to rotate, it can only compensate for the increased distance by performing circular wave motion. The staff can adjust the rising height of the driving shaft 301 according to the amount of feed. The greater the rising height, the greater the rotation amplitude of the sieve plate 102. While the sieve plate 102 is shaking, calcium aluminate can move in the sieve plate 102 and fall into the reaction solution through the sieve hole 102a.
[0042] Since the rotating member 202 is connected to the limiting arm 101, when the limiting arm 101 swings, it will drive the driven rotating shaft 201 to swing around the control axis 305, and then the stirring shaft 203 will also swing around the control axis 305, and the stirring blade 203a will stir the reaction solution to make it fully react. The greater the rising height of the driving rotating shaft 301, the greater the swing amplitude of the stirring shaft 203, and the better the stirring effect.
[0043] When the feed volume is large, the sieve plate 102 needs to rotate with a larger amplitude to avoid the accumulation of raw materials. At the same time, when there are many reactants, a higher stirring speed is required. Therefore, the setting of the adjustment component 300 can make the screening component 100 and the stirring component 200 change the movement rate synchronously, which is more in line with the actual production needs.
[0044] Example 3
[0045] Reference Figure 5-6 , which is the third embodiment of the utility model. This embodiment is different from the first embodiment in that it also includes a reaction box 400, the back plate 304 is fixedly arranged in the reaction box 400, a feed pipe 401 and a heat dissipation hole 402 are opened on the box body of the reaction box 400, and a material collection drawer 403 is also slidably arranged on the reaction box 400.
[0046] Since a large amount of heat is generated during the reaction, if the heat is not dissipated in time, excessive heat may cause the reaction to get out of control or even cause an explosion. High temperature may also cause damage to the reactor and other equipment, including deformation, corrosion, wear, etc., thus affecting the life and safety of the equipment.
[0047] Therefore, heat dissipation holes 402 are provided on the surface of the reaction box 400 to discharge the heat upward in time. The material taking drawer 403 is provided at the bottom of the reaction box 400 to facilitate the staff to collect the polymer deposited at the bottom of the reaction box 400 after the preparation reaction is completed.
[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
