[0003] In the preparation process of various types of mortars, a mixing device is often required to mix various raw materials of the mortar. The mixing device is generally designed with a stirring structure to quickly mix the raw materials. However, different mortars have different raw materials and different viscosities. Therefore, in the preparation process of such building insulation materials, if the mixing is not thorough enough, agglomeration or lumps will occur, which will affect the uniformity of the finished mortar.

[0004] In the prior art, the clumps are generally broken up by increasing the rotation speed of the stirring blades.

[0015] A method for preparing a building thermal insulation material, using the above-mentioned building thermal insulation material preparation device, comprises the following steps:

[0016] S1: First, the raw materials are put into the mixing drum through the hopper, and the cylinder and the motor are started.

[0023] 2. The preparation device and preparation method of the building insulation material, when the mixing component moves up and down and rotates reciprocatingly in the mixing barrel, the top block repeatedly enters the interior of the rotating shaft, and then pushes the two embedded stirring blades to be ejected reciprocally, and under the limit of the middle filter plate, the embedded stirring blades are reciprocated and recovered, thereby allowing the embedded stirring blades to turn over and stir the mortar raw materials during the reciprocating ejection and recovery process. At the same time, under the linkage of the motor, the rotating shaft drives the embedded stirring blades to rotate, and then performs horizontal stirring, thereby further improving the uniformity of the mortar raw material mixing.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] See also Figure 1-9, a preparation device for building thermal insulation materials, including a gantry 1 and a controller, a mixing drum 11 is fixed to the inner side of the gantry 1 by bolts, a top cover 12 is fixed to the top of the mixing drum 11, hoppers 13 are fixed to both sides of the top of the top cover 12, the hopper 13 is connected to the top cover 12, a middle filter plate 2 is fixed to the inner wall of the mixing drum 11 by bolts, a cylinder 3 is fixed to the top of the gantry 1, an output shaft of the cylinder 3 passes through the horizontal part of the gantry 1, a motor 31 is fixed to the outside of the output shaft of the cylinder 3, the cylinder 3 and the motor 31 are both controlled by the controller, a mixing assembly is arranged outside the output shaft of the motor 31, and the mixing assembly is used to mix the raw materials of the building thermal insulation materials;

[0037] The mixing assembly includes a connecting rod 4, which is fixed to the output shaft of the motor 31, a rotating shaft 41 is fixed to the bottom of the connecting rod 4, and the rotating shaft 41 is slidably connected to the middle filter plate 2, an upper fan blade 42 is fixed to the surface of the rotating shaft 41, an upper pressure plate 43 is fixed to the surface of the rotating shaft 41 below the upper fan blade 42, and the upper fan blade 42 is fixed to the upper pressure plate 43, a lower pressure plate 44 is fixed to the surface of the rotating shaft 41 below the upper pressure plate 43, a lower fan blade 45 is fixed to the surface of the rotating shaft 41 below the lower pressure plate 44, and the lower fan blade 45 is fixed to the lower pressure plate 44, a discharge pipe 6 is fixed to the bottom of the mixing barrel 11, and the discharge pipe 6 is connected to the mixing barrel 11, and an electric telescopic rod 61 is fixed inside the discharge pipe 6;

[0038] During the specific operation, the raw materials of the mortar are first put into the interior of the mixing barrel 11 through the hopper 13, and then the motor 31 is started through the controller, and the motor 31 drives the connecting rod 4 to rotate, and the connecting rod 4 drives the rotating shaft 41 to rotate. During the rotation of the rotating shaft 41, the upper blades 42, the upper pressure plate 43, the lower pressure plate 44 and the lower blades 45 are driven to rotate at the same time, so that the motor 31 can link the entire mixing assembly to rotate, and the upper blades 42 and the upper pressure plate 43 are located above the middle filter plate 2, and the lower pressure plate 44 and the lower blades 45 are located below the middle filter plate 2, so that the upper blades 42 and the upper pressure plate 43 mix the raw materials above the middle filter plate 2, and the lower pressure plate 44 and the lower blades 45 mix the raw materials below the middle filter plate 2;

[0039] Specifically, during the mixing process, the cylinder 3 is started by the controller, so that the cylinder 3 performs periodic ejection and return. During the ejection process, the cylinder 3 drives the motor 31 to eject, so that the motor 31 drives the entire mixing component to move up and down inside the mixing barrel 11. While the entire mixing component is moving up and down, the mixing component is driven by the motor 31 to rotate at the same time, so that the upper blades 42, the upper pressure plate 43, the lower pressure plate 44 and the lower blades 45 are inside the mixing barrel 11 and above and below the middle filter plate 2. The raw materials are stirred horizontally and vertically at the same time, thereby improving the uniformity of the raw material mixing, and in the process of the upper blades 42, the upper pressure plate 43, the lower pressure plate 44 and the lower blades 45 moving up and down, the lumps in the raw materials are broken;

[0040] Furthermore, in actual operation, when the upper platen 43 and the lower platen 44 move back and forth in the mixing drum 11, the distance between the upper platen 43 and the lower platen 44 and the middle filter plate 2 gradually approaches, and then gradually moves away. In the process of the upper platen 43 and the lower platen 44 approaching, the agglomerates formed in the middle of the upper platen 43 and the middle filter plate 2 are squeezed and crushed by the middle filter plate 2 and the upper platen 43, while the agglomerates formed in the middle of the lower platen 44 and the middle filter plate 2 are squeezed and crushed by the middle filter plate 2 and the lower platen 44. Then, the agglomerates formed in all directions in the mixing drum 11 are squeezed and crushed, thereby improving the uniformity of the mixing of the mortar raw materials of the present invention.

[0041] Furthermore, when the motor 31 drives the entire mixing assembly to rotate, that is, when the motor 31 drives the rotating shaft 41 to link the upper pressure plate 43 and the lower pressure plate 44 to rotate inside the mixing barrel 11, since the mixing barrel 11 is in contact with the outer edges of the upper pressure plate 43 and the lower pressure plate 44, the upper pressure plate 43 and the lower pressure plate 44 always maintain a friction state with the mixing barrel 11 during the rotation and lifting and lowering movements, and the contact part of the mixing barrel 11 with the upper pressure plate 43 and the lower pressure plate 44 generates heat during the friction process, and then the heat is transferred to the mortar in the mixing barrel 11. By increasing the temperature of each raw material in the mixing barrel 11, the raw materials are softened, and the uniformity of the mixing of the mortar raw materials is further improved.

[0042] It should be noted that filter holes are provided on the surfaces of the upper pressure plate 43, the lower pressure plate 44 and the middle filter plate 2, thereby ensuring that the mortar raw materials can flow through the upper pressure plate 43 and the lower pressure plate 44 during the lifting and lowering movement, thereby ensuring the smooth movement of the upper pressure plate 43 and the lower pressure plate 44.

[0043] Embodiment 2:

[0044] An embedded groove 5 is provided inside the rotating shaft 41, and embedded stirring blades 51 are hinged on both sides of the top of the embedded groove 5. The opposite sides of the bottom ends of the two embedded stirring blades 51 are arranged in an inclined surface. A through groove 52 is provided at the bottom end of the embedded groove 5, and the embedded groove 5 and the through groove 52 are connected to each other. A limiting notch 53 is provided on the inner wall of the through groove 52. A sealing disc 7 is slidably connected to the inner wall of the discharge pipe 6. A vertical rod 71 is fixed on the top of the sealing disc 7. A top block 72 is fixed on the top of the vertical rod 71. An annular groove 77 is provided on the outer side of the sealing disc 7, and the annular groove 77 is slidably connected to the output shaft of the electric telescopic rod 61.

[0045] During the specific operation, when the cylinder 3 is started, the cylinder 3 drives the motor 31 to link the entire mixing assembly to move up and down reciprocatingly inside the mixing barrel 11. During the reciprocating movement of the mixing assembly, the rotating shaft 41 moves up and down reciprocatingly inside the mixing barrel 11. During the movement of the rotating shaft 41, the rotating shaft 41 drives the embedded stirring blade 51 to move up and down synchronously. During the movement of the embedded stirring blade 51, the embedded stirring blade 51 gradually approaches the sealing disk 7 and then gradually moves away from the sealing disk 7, and the cycle repeats.

[0046] Specifically, when the embedded stirring blade 51 and the sealing disk 7 gradually approach each other, the top block 72 passes through the through slot 52 and enters the interior of the embedded slot 5, and contacts the two embedded stirring blades 51. As the embedded stirring blade 51 continues to approach the sealing disk 7, the embedded stirring blade 51 is continuously limited by the top block 72, and then the two embedded stirring blades 51 are turned toward the two sides of the rotating shaft 41 until the bottom of the rotating shaft 41 is completely in contact with the sealing disk 7. At this time, the angle between the embedded stirring blade 51 and the vertical rod 71 is 45 degrees.

[0047] At this time, the opened embedded stirring blade 51 is located in the middle of the lower pressure plate 44 and the middle filter plate 2, and the lower fan blade 45 is located at the bottom of the mixing barrel 11 and does not contact the bottom of the mixing barrel 11. Therefore, when the motor 31 drives the entire mixing assembly to rotate, the rotating shaft 41 drives the embedded stirring blade 51 to rotate inside the mixing barrel 11, and during the rotation process, the mortar raw materials are mixed and stirred. At the same time, the rotating embedded stirring blade 51 can break some lumps in the raw materials, thereby improving the uniformity of the mortar raw material mixing;

[0048] The inner stirring blade 51 is moved away from the sealing plate 7 by the rotating shaft 41, and the inner stirring blade 51 is moved away from the top block 72, so that the limit of the inner stirring blade 51 by the top block 72 is gradually reduced. At the same time, the distance between the inner stirring blade 51 and the middle filter plate 2 is gradually approached, until the inner stirring blade 51 contacts the middle filter plate 2 and is limited by the middle filter plate 2. The inner stirring blade 51 is gradually retracted into the inner groove 5 until the entire inner stirring blade 51 is completely retracted into the inner groove 5. At this time, the cylinder 3 is completely reset, that is, the upper pressing plate 43 is located at the highest point of the stroke inside the mixing barrel 11, and the inner stirring blade 51 follows the rotating shaft 41 to penetrate the middle filter plate 2, but does not completely pass through the middle filter plate 2, thereby avoiding the inner stirring blade 51 from opening from the inside of the inner groove 5 above the middle filter plate 2, and ensuring that the inner stirring blade 51 can only be opened at the middle position between the lower pressing plate 44 and the middle filter plate 2.

[0049] Furthermore, when the cylinder 3 drives the motor 31 to link the entire mixing assembly to move back and forth and up and down inside the mixing barrel 11, the embedded stirring blade 51 follows the rotating shaft 41 and is repeatedly opened and recovered in the middle position between the lower pressure plate 44 and the middle filter plate 2. In the process of repeated opening and recovery of the embedded stirring blade 51, the mortar in the middle position between the lower pressure plate 44 and the middle filter plate 2 is turned over, i.e., longitudinally stirred, thereby improving the uniformity of the mortar raw material mixing and the comprehensiveness of the broken lumps.

[0050] It should be noted that when the upper pressing plate 43 reaches the highest point of the stroke inside the mixing cylinder 11, the top block 72 is still located inside the through groove 52, thereby avoiding the problem of calibration between the top block 72 and the embedded groove 5, so that when the rotating shaft 41 is descending, the top block 72 can directly pass through the through groove 52 and enter the inside of the embedded groove 5;

[0051] The shape of the embedded groove 5 is flat, and the vertical rod 71 and the top block 72 are both flat, that is, after the top block 72 and the vertical rod 71 enter the interior of the embedded groove 5, the vertical rod 71 and the top block 72 contact and abut against the inner wall of the embedded groove 5, that is, the vertical rod 71 and the top block 72 are in a sliding connection with the embedded groove 5;

[0052] The portion of the middle filter plate 2 that is close to the sealing plate 7 and in sliding contact with the rotating shaft 41 is arranged in an inclined surface, thereby reducing the mechanical impact of the embedded stirring blade 51 when it contacts the middle filter plate 2.

[0053] Embodiment three:

[0054] An internal groove 73 is provided inside the vertical rod 71 near one end of the sealing disk 7, an electromagnet 74 is fixed to the inner wall of one side of the internal groove 73, a magnetic rod 75 is slidably connected inside the internal groove 73, the electromagnet 74 and the magnetic rod 75 have the same magnetic properties, a spring 76 is fixed to the inner wall of the magnetic rod 75, and one end of the spring 76 is fixed to the inner wall of the internal groove 73, the bottom of the inner cavity of the mixing barrel 11 is conical, and a bottom fan blade 8 is fixed to the top of the sealing disk 7, the bottom fan blade 8 does not contact the moving trajectory of the lower fan blade 45, and does not contact the bottom of the mixing barrel 11;

[0055] During the specific operation, on the basis of the first and second embodiments, since the vertical rod 71, the top block 72 and the embedded groove 5 are in a sliding connection state, when the motor 31 drives the rotating shaft 41 to rotate, the rotating shaft 41 drives the top block 72 and the vertical rod 71 to rotate synchronously, and then the vertical rod 71 drives the sealing plate 7 to rotate synchronously, and the sealing plate 7 drives the bottom fan blades 8 to rotate synchronously. During the rotation process, the bottom fan blades 8 mix and stir the mortar raw materials at the bottom of the mixing barrel 11, which makes up for the lack of stirring after the lower fan blades 45 are away from the bottom of the mixing barrel 11, thereby making the mortar raw materials at the bottom of the mixing barrel 11 more fully mixed;

[0056] Furthermore, after the mixing is completed, when it is necessary to discharge the material, the receiving container is first placed under the discharge pipe 6, and then the cylinder 3 is started by the controller to be pushed out to the maximum stroke, that is, the cylinder 3 drives the motor 31 to link the mixing assembly and move to the lowest point of the internal stroke of the mixing barrel 11, that is, the rotating shaft 41 is against the sealing disk 7. At this time, the electromagnet 74 is started by the controller, and the electromagnet 74 generates magnetic force after being energized, and repels the magnetic rod 75, pushing the magnetic rod 75 out of the interior of the built-in groove 73, so that the magnetic rod 75 is clamped into the interior of the limited notch 53, thereby fixing the vertical rod 71 and the rotating shaft 41, and then fixing the rotating shaft 41 and the sealing disk 7;

[0057] Then, the electric telescopic rod 61 is started by the controller, so that after the electric telescopic rod 61 returns, the limit of the electric telescopic rod 61 on the annular groove 77 is released, and then the sealing plate 7 loses the lock of the electric telescopic rod 61. When the cylinder 3 returns, the cylinder 3 drives the motor 31 to link the entire mixing assembly to return, and then the rotating shaft 41 drives the sealing plate 7 to move toward the cylinder 3, thereby causing the sealing plate 7 to gradually separate from the discharge pipe 6 and the mixing barrel 11, and then the discharge pipe 6 and the mixing barrel 11 are connected to each other. At this time, the mixed material can fall into the receiving container through the discharge pipe 6;

[0058] After the unloading is completed, the cylinder 3 can be started again to drive the motor 31 to push out the mixing assembly, and then the rotating shaft 41 drives the vertical rod 71 and the sealing disk 7 to re-engage the inside of the feeding and discharging pipe 6, and the electric telescopic rod 61 is started again, so that the electric telescopic rod 61 is pushed out and engaged into the inside of the annular groove 77, and then the sealing disk 7 is locked. Subsequently, the electromagnet 74 is controlled to be powered off. After the electromagnet 74 is powered off, the magnetic rod 75 is reset under the pulling force of the spring 76 and recovered into the inside of the built-in groove 73.

[0059] It should be noted that the initial state of the electric telescopic rod 61 is the ejected state, and the closed end of the magnetic rod 75 is made of a magnetic plate, and the rod body of the magnetic rod 75 is made of high-temperature resistant plastic.

[0060] A method for preparing a building thermal insulation material, using the above-mentioned building thermal insulation material preparation device, comprises the following steps:

[0061] S1: First, the raw materials are put into the mixing barrel 11 through the hopper 13, and the cylinder 3 and the motor 31 are started. The motor 31 drives the connecting rod 4 and the rotating shaft 41 to rotate, and the rotating shaft 41 drives the upper blade 42, the upper pressing plate 43, the lower pressing plate 44 and the lower blade 45 to rotate inside the mixing barrel 11, and then the raw materials are mixed;

[0062] S2: During the mixing of raw materials, the cylinder 3 is controlled to continuously eject and return, and then the cylinder 3 drives the motor 31 to reciprocate and lift inside the mixing barrel 11, and the motor 31 links the rotating shaft 41, the upper fan blades 42, the upper pressure plate 43, the lower pressure plate 44 and the lower fan blades 45 to reciprocate and lift inside the mixing barrel 11, thereby improving the mixing range and uniformity;

[0063] S3: During the reciprocating lifting and lowering process of the rotating shaft 41, the upper fan blades 42, the upper pressure plate 43, the lower pressure plate 44 and the lower fan blades 45, the upper pressure plate 43 and the lower pressure plate 44 contact with the top and bottom of the middle filter plate 2 in turn, and during the contact process, the lumps in the mixed material are squeezed and crushed to improve the uniformity of the mixing;

[0064] S4: During the lifting process, the rotating shaft 41 drives the embedded stirring blades 51 to repeatedly contact the top block 72, so that the two embedded stirring blades 51 are repeatedly pushed out under the limit of the top block 72, and repeatedly recovered under the limit of the middle filter plate 2, so as to further mix the raw materials;

[0065] S5: After the mixing is completed, the electromagnet 74 is started to generate magnetic force, which pushes the magnetic rod 75 out and snaps into the interior of the limited slot 53, so that the magnetic rod 75 is fixed to the rotating shaft 41, and the magnetic rod 75 drives the vertical rod 71 and the sealing plate 7 to be fixed to the rotating shaft 41. After the cylinder 3 is controlled to return, the cylinder 3 drives the rotating shaft 41 to move the sealing plate 7 toward the cylinder 3, so that the discharge pipe 6 is fully connected with the mixing barrel 11, so that the mixed material can be discharged.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
