Description
Technical Field
[0001] The utility model relates to the field of auxiliary components for alpha high-strength gypsum production, in particular to a tank agitator structure. Background Art
[0002] Industrial by-product gypsum refers to the by-product or waste residue with calcium sulfate as the main component generated by chemical reactions in industrial production, also known as chemical gypsum or industrial waste gypsum. Using industrial waste gypsum as raw material to prepare α high-strength gypsum is an emerging industrial waste gypsum utilization technology, which can effectively solve the problem of industrial by-product gypsum storage. In the process of preparing α high-strength gypsum with industrial waste gypsum as raw material, the main process principle is: industrial by-product gypsum powder (the main component is dihydrate calcium sulfate CaSO4.2H2O) is mixed and stirred with a certain proportion of water and a crystallization agent to form a dihydrate gypsum slurry, which enters the autoclave reactor. Under pressurized and heated conditions, the dihydrate gypsum in the slurry doubles. The structure is destroyed, 3 / 4 of the H2O between the two ion layers is lost, and the remaining H2O recrystallizes with CaSO4 to become α-type hemihydrate high-strength gypsum crystals. During the reaction of the gypsum slurry in the reactor, a stirrer structure needs to be set in the reactor to fully stir and mix the slurry. However, when the current stirrer structure is specifically designed, it can usually only stir the slurry in a reciprocating circumferential direction by rotating the stirring blades. Since the stirring method has obvious stratification, the mixing degree of the slurry and the crystal-changing agent at each height is inconsistent, which leads to the inconsistency of the recrystallization process of the slurry at each height, and the stirring effect is not very good.

[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0032] See also Figure 1-Figure 10 As shown, the utility model provides a tank agitator structure, including a stirring shaft body 1, the axis of the stirring shaft body 1 is vertically arranged, and a stirring component 2 is coaxially fixedly installed in the middle of the outer periphery of the stirring shaft body 1. Specifically, the stirring component 2 includes a mounting sleeve 201 and a stirring blade 202, and the mounting sleeve 201 is coaxially fixed in the middle of the outer periphery of the stirring shaft body 1. Preferably, the mounting sleeve 201 can be fixed to the outer periphery of the stirring shaft body 1 by a key connection or a coaxial interference fit, and a plurality of stirring blades 202 are extended and fixed to the outer periphery of the mounting sleeve 201. Such an arrangement makes it easy to stir the slurry in the reactor tank by driving the stirring blades 202 to rotate through the stirring shaft body 1.
[0033] The lower part of the stirring shaft body 1 is coaxially and detachably installed with a swirl component 3 that can generate a swirl during stirring to drive the slurry to surge upward. Specifically, the swirl component 3 includes a limiting hole 301 and a sliding sleeve 302. The lower part of the stirring shaft body 1 is radially provided with a plurality of limiting holes 301. The sliding sleeve 302 is coaxially slidably fitted in the lower part of the stirring shaft body 1. A plurality of swirl plates 305 extending radially outward are installed on the outer lower part of the sliding sleeve 302. A mounting hole 307 is radially provided on the front of the upper part of the outer periphery of the sliding sleeve 302. The mounting hole 307 is coaxially aligned with one of the limiting holes 301. The mounting hole 307 is longitudinally coaxially slidably fitted with a limiting rod 306, and the rear end of the limiting rod 306 is longitudinally aligned with the corresponding limiting hole 301. The front end of the limit rod 306 extends out of the front outer part of the sleeve 302 and is coaxially fixed with the handle 304. The limit rod 306 is located between the handle 304 and the outer surface of the sleeve 302 and is fitted with a spring 303 in the coaxial gap. The two ends of the spring 303 are respectively fixedly connected to the handle 304 and the outer surface of the sleeve 302. This arrangement makes it easy to detach the sleeve 302 and the outer swirl blades on the lower part of the agitator shaft body 1 by means of axial vertical sliding cooperation between the sleeve 302 and the lower part of the agitator shaft body 1 and radial sliding cooperation between the limit rod 306 and the limit hole 301. At the same time, the sleeve 302 and the outer swirl blades can be detached from the lower end of the agitator shaft body 1 by simply pulling the limit rod 306 out of the limit hole 301.
[0034] As a preferred solution in this case, a coupling 101 is installed at the top of the stirring shaft body 1 to facilitate coaxial connection with the motor shaft. This arrangement makes it convenient to connect the top of the stirring shaft body 1 with the bottom of the motor shaft by setting the coupling 101, and then drive the stirring shaft to rotate by the motor shaft. A plurality of stirring blades 202 are evenly distributed circumferentially around the periphery of the mounting sleeve 201, and the stirring blades 202 are all L-shaped plates. This arrangement makes it convenient for the stirring blades 202 to have a larger stirring range during the turnover stirring process. The stirring blades 202 are evenly opened with a plurality of slurry holes 203. This arrangement makes it convenient for the stirring blades 202 to allow the slurry to flow through the stirring blades 202 through the slurry holes 203 during the stirring of the slurry, which is beneficial to improving the stirring and mixing effect.
[0035] At the same time, multiple swirl plates 305 are arranged in a fan-blade style in the axial direction. At the same time, the swirl plates 305 are rectangular long strips and have a certain angle with the horizontal plane. Such a configuration is convenient for the agitator shaft body 1 to drive the sleeve 302 and the peripheral swirl blades to rotate.

Multiple limit holes 301 are evenly distributed in the vertical direction, and the limit holes 301 are all through holes. Such a configuration is convenient for the sleeve 302 to slide along the agitator shaft coaxially, and the limit rod 306 can slide and cooperate with the limit hole 301 coaxially from two directions, which is more convenient for the sleeve 302 to be fixed on the periphery of the agitator shaft body 1.
[0036] With the above structure, during the stirring of the reactor tank, the sleeve 302 and the peripheral swirl blades can be detachably fixed to the lower part of the stirring shaft body 1 by means of the axial vertical sliding cooperation between the sleeve 302 and the lower part of the stirring shaft body 1 and the radial sliding cooperation between the limit rod 306 and the limit hole 301. The sleeve 302 and the peripheral swirl blades can be detached from the lower end of the stirring shaft body 1 by simply pulling the limit rod 306 out of the limit hole 301. The combination and disassembly of the sleeve 302 and the peripheral swirl blades with the stirring shaft body 1 is simple and easy to operate. At the same time, since the swirl plate 305 is a rectangular long strip and forms a certain angle with the horizontal plane, and the multiple swirl blades on the periphery of the sleeve 302 are arranged in a fan blade style, it is convenient to stir In the process of the mixing shaft body 1 driving the sleeve 302 and the outer swirl blades to rotate, an upward swirling flow can be formed, so that the slurry can be driven to continuously surge upward for cyclic stirring during the process of the mixing blades 202 stirring the slurry, ensuring that the degree of mixing of the slurry and the crystallization agent at each position height is consistent, which is beneficial to improving the stirring effect. In addition, since a plurality of vertically evenly distributed limit holes 301 are provided at the lower part of the mixing shaft, during the installation stage before the agitator enters the reactor tank body, the initial position height of the sleeve 302 and the outer swirl blades can be adjusted by coaxially cooperating with the limit rod 306 and the limit holes 301 at different positions, so that the outer swirl blades can be adjusted to a position height that meets actual use needs for use.
[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
