Description

Technical Field

[0001] This utility model relates to the field of fire-retardant coating technology, and in particular to a composite mixing head for a fire-retardant coating mixer. Background Technology

[0002] As a special functional material that improves the fire resistance of the substrate, the uniformity of mixing during the preparation process of fire-retardant coatings directly determines the fire-retardant performance and construction effect of the coatings. In production, fire-retardant coatings are mixed by a mixer. The core working principle is to apply force to the coating by rotating the stirring head to achieve mixing, dispersion or suspension.

[0003] However, the existing mixing heads used in fire-retardant coating production mixers have the following problems:

[0004] First, fire-retardant coatings are usually highly viscous. However, the mixing heads of existing mixers can usually only apply sufficient force to high-viscosity materials radially, but cannot axially turn the materials up and down for mixing, which easily leads to incomplete mixing.

[0005] Secondly, the blades of existing stirring heads usually cannot reduce the radial force on the stirring head by disassembling the blades. The blades bear non-uniform radial loads in viscous media, which easily generate periodic eccentric vibrations, accelerate the wear of the main shaft bearings, and even break them. Utility Model Content

[0006] In view of the above-mentioned problems in the prior art, a composite mixing head for a fireproof coating mixer is provided.

[0007] The specific technical solution is as follows:

[0008] A composite mixing head for a fire-retardant coating mixer is designed, comprising a main body, rectangular blades, and a limiting end. The top of the main body is fixedly connected to support members arranged at equal intervals, the top of the support members is fixedly connected to a top ring, the inner side of the support members is fixedly connected to a helical blade, the center of the helical blade is fixedly connected to a rotating rod, and the outer side of the support members is fixedly connected to the rectangular blade.

[0009] Preferably, the rectangular blade has a first connecting hole at the top and a second connecting hole at the bottom.

[0010] Preferably, the rectangular blade has a disassembly plate inside and a square hole at the center.

[0011] Preferably, a fixing post is fixedly connected to the top of the limiting end, the fixing post passing through the first connecting hole, the second connecting hole and the square hole, and the cross-section of the fixing post is square.

[0012] Preferably, a threaded post is fixedly connected to the top of the fixed post, a hexagonal nut is provided at the top of the first connecting hole, a threaded hole is provided at the center of the hexagonal nut, and the threaded post is threaded into the threaded hole.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] 1. When using this stirring head to stir high-viscosity liquids, the rectangular blades and disassembly plate drive the liquid to move radially, that is, drive the liquid to rotate. At the same time, the device is equipped with spiral blades that can drive the liquid to move axially, that is, to tumble up and down, so that this device can tumble the material up and down compared with traditional mixers, making the material more thoroughly mixed.

[0015] 2. This device can be disassembled by rotating the hexagonal nut with a wrench, and then the disassembly plate and the fixing column can be removed. Stirring is carried out by only rectangular blades, which can reduce the radial force during stirring, thereby reducing the unbalanced impact force at the connection between the rectangular blades and the support, and increasing its service life. When it is necessary to enhance the mixing performance, the disassembly plate can be reinstalled. Attached Figure Description

[0022] 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.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0025] Reference Figure 1-4 A composite mixing head for a fireproof coating mixer includes a main body 1, rectangular blades 2, and a limiting end 3. The top of the main body 1 is fixedly connected to equally spaced support members 103. A top ring 104 is fixedly connected to the top of the support members 103. A spiral blade 101 is fixedly connected to the inner side of the support members 103. A rotating rod 102 is fixedly connected to the center of the spiral blades 101. The rectangular blades 2 are fixedly connected to the outer side of the support members 103. The top of the rotating rod 102 is fixedly connected to the output shaft of the mixer's mixing motor. When this device is used for mixing, the rectangular blades 2 drive the liquid to move radially, i.e., rotate the liquid, while the spiral blades 101 drive the liquid axially, i.e., tumble up and down.

[0026] Furthermore, the rectangular blade 2 has a first connecting hole 203 at the top and a second connecting hole 204 at the bottom. The first connecting hole 203 and the second connecting hole 204 are square, which is easier to clean than a circular threaded hole.

[0027] Furthermore, the rectangular blade 2 is provided with a disassembly plate 201 inside, and a square hole 202 is provided in the center of the rectangular blade 2. The disassembly plate 201 of this device can be disassembled. When it is necessary to stir a high viscosity liquid with a large viscosity, the disassembly plate 201 is retained. When it is necessary to stir a liquid with good fluidity, the disassembly plate 201 can be disassembled to reduce the radial force during stirring.

[0028] Furthermore, a fixing post 302 is fixedly connected to the top of the limiting end 3. The fixing post 302 passes through the first connecting hole 203, the second connecting hole 204 and the square hole 202. The cross-section of the fixing post 302 is square, which fixes the disassembly plate 201.

[0029] Furthermore, the top of the fixed column 302 is fixedly connected to the threaded column 303, the top of the first connecting hole 203 is provided with a hexagonal nut 301, the center of the hexagonal nut 301 is provided with a threaded hole 304, the threaded column 303 is threadedly connected to the threaded hole 304 to fix the disassembly plate 201.

[0030] Working principle: When using this stirring head to stir high-viscosity liquids, the rectangular blades 2 and the disassembly plate 201 drive the liquid to move radially, i.e., rotate the liquid. At the same time, the device is equipped with a spiral blade 101, which can drive the liquid to move axially, i.e., tumble up and down, when it rotates. Compared with traditional mixers, this device can tumble the material up and down, making the material more thoroughly mixed. The device can be disassembled by rotating the hexagonal nut 301 with a wrench, and then the disassembly plate 201 and the fixing column 302 can be removed. Stirring is carried out by the rectangular blades 2 alone, which can reduce the radial force during stirring, thereby reducing the unbalanced impact force at the connection between the rectangular blades 2 and the support 103 and increasing its service life. When it is necessary to enhance the mixing performance, the disassembly plate 201 can be reinstalled.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
