[0002] Refractory castable refers to a mixture composed of refractory aggregates, binders and additives, which is mixed with water (or liquid binder) to form a mud that can be constructed by casting method.

Based on this, a mixing mechanism for processing refractory castables is provided. Content of the Utility Model

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a mixing mechanism for processing refractory castables includes a mixing component 1 composed of a stirring barrel 101, a driving mechanism 102, and a stirring blade 103. The driving mechanism 102 is installed at the bottom end of the stirring barrel 101, and the output shaft of the driving mechanism 102 penetrates through the center position at the bottom of the stirring barrel 101 and extends into the stirring barrel 101. A plurality of stirring blades 103 are provided, and the plurality of stirring blades 103 are fixedly installed circumferentially outside the driving mechanism 102 and are located inside the stirring barrel 101. A dust reduction component 2 is provided at the top of the stirring barrel 101, and the dust reduction component 2 is used to collect the dust generated during the feeding and stirring processes.

[0020] The dust reduction component 2 includes a dust removal unit, a fixing unit, and a discharging unit.

[0021] The fixing unit is used to realize the installation connection between the dust removal unit and the stirring barrel 101.

[0022] The dust removal unit is used to suck and collect the dust.

[0023] The discharging unit is used to discharge the dust collected by the dust removal unit back into the stirring barrel 101 to realize the recycling of the dust raw materials.

[0024] The dust removal unit includes a conical collection barrel 203, a dust removal box cover 204, a suction port 205, an exhaust blower 206, and a filter cartridge 207; the dust removal box cover 204 is fixed on the top of the conical collection barrel 203, the conical collection barrel 203 and the dust removal box cover 204 are distributed above the stirring barrel 101, and the suction port 205 is opened at the bottom of the dust removal box cover 204.

[0025] The suction fan 206 is installed at the central position on the top of the dust removal box cover 204, and a ventilation opening communicating with the suction port of the suction fan 206 is provided at the top inner wall of the dust removal box cover 204. The filter cartridge 207 is installed inside the ventilation opening and extends to the inside of the conical collection cylinder 203.

[0026] When the suction fan 206 operates, it generates suction to suck external dust into the conical collection cylinder 203 through the dust removal box cover 204, realizing the dust collection operation.

[0027] The fixing unit includes fixing grid bars 201 and a fixing cover 202; the fixing cover 202 is fixed to the outside of the conical collection cylinder 203. There are multiple fixing grid bars 201, and the multiple fixing grid bars 201 are circumferentially distributed and fixed to the inner top of the mixing barrel 101, and the multiple fixing grid bars 201 are fixedly connected to the bottom of the fixing cover 202.

[0028] The discharging unit includes a conical block 208 and an auger 209; the conical block 208 is fixed to the top of the output shaft of the driving mechanism 102, and the auger 209 is fixed to the top of the conical block 208 and penetrates to the inside of the conical collection cylinder 203.

[0029] When the driving mechanism 102 operates, it drives the auger 209 to rotate, which is used to convey the dust collected inside the conical collection cylinder 203 downward into the mixing barrel 101.

[0030] In this embodiment: when this device is in use, during the process of pouring raw materials into the mixing barrel 101 and dry mixing, the suction fan 206 can be started synchronously. The suction fan 206 generates suction during operation, and this suction sucks external dust through the suction port 205, so as to avoid the outward diffusion of dust during the feeding and dry mixing processes.

[0031] The dust sucked into the dust removal box cover 204 is intercepted by the filter cartridge 207, and then the dust will fall under its own weight and be collected inside the conical collection barrel 203.

[0032] At the same time, the driving mechanism 102 operates to drive the mixing blades 103 to mix and stir the raw materials (it should be noted that: the driving mechanism 102 is composed of parts such as a motor, a pulley, a belt, and an output shaft. The motor operates to drive the output shaft to rotate through the transmission of the pulley and the belt, and the output shaft drives the mixing blades 103 to rotate. Since this structure is an existing technical structure, it is not described in detail here). In addition, the output shaft of the driving mechanism 102 can synchronously drive the auger 209 to rotate. The rotation of the auger 209 can convey the dust collected inside the conical collection barrel 203 downward into the mixing barrel 101, and its conical block 208 makes the downward-conveyed dust fall around, so that while realizing the recovery of raw material dust, the uniform mixing of raw materials can be realized.

[0033] It should be noted that during the downward transportation of dust by the auger 209, the dust will be squeezed by the auger 209, so that the dust is in a compressed state with each other. In this way, during the falling process, no large amount of dust will be generated.

[0034] Please refer specifically to Figures 2 to 3 , there are multiple groups of suction ports 205. Each group of suction ports 205 includes a plurality of suction ports 205 distributed in a circle. And the multiple groups of suction ports 205 are distributed in sequence from the inside to the outside, and the diameter of the distribution trajectory of the outermost suction port 205 is greater than the outer diameter of the mixing barrel 101.

[0035] In this embodiment: Through this structure, the omnidirectional dust suction operation of the space above the mixing barrel 101 can be realized, thus ensuring an efficient dust reduction effect.

[0036] Please refer specifically to Figure 1 , 3 , the top horizontal height of the fixed grille rod 201 is lower than the top horizontal height of the mixing barrel 101, and the conical block 208 and the auger 209 are distributed inside the fixed cover 202.

[0037] In this embodiment: The raw materials of the refractory castable are packaged in packaging bags. During the process of pouring the materials, the fixed grille rod 201 can provide support for the placement of the packaging bags;

[0038] When the auger 209 drives the powder to move downward, the fixed cover 202 can intercept the small amount of dust generated during this process. After that, most of these dusts can fall back into the mixing barrel 101 under the action of their own weight, thus further reducing the loss of raw materials.

[0039] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
