Description

Technical Field

[0001] The invention relates to the technical field of mortar, and in particular to a method for preparing thermal insulation mortar. Background Art

[0002] Building thermal insulation mortar refers to a mortar composed of cementitious materials, lightweight aggregates and other functional additives that can insulate building walls. It has the advantages of good construction performance, stable material performance, and good environmental safety. It is a widely used building thermal insulation material. At present, when preparing thermal insulation mortar, the raw materials required for preparing thermal insulation mortar are generally placed in a mixing equipment and stirred. However, this preparation method has some serious problems:

[0003] 1. When preparing the thermal insulation mortar, it is necessary to add vitrified microspheres to the cement, and then stir to mix the vitrified microspheres and cement evenly. Since the vitrified microspheres will greatly reduce the thermal insulation effect after being broken, the stirring speed can only be slowed down to ensure that the vitrified microspheres are not broken, resulting in uneven distribution of vitrified microspheres in the thermal insulation mortar, causing inconsistent quality of the thermal insulation mortar;

[0004] 2. When preparing the thermal insulation mortar, due to the high viscosity of the thermal insulation mortar, it takes a long time to pour out the thermal insulation mortar, and a large amount of thermal insulation mortar will stick to the inner wall of the mixing container, making it difficult to clean.

[0018] Beneficial Effects

[0019] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0020] 1. In the present invention, the sleeve is provided so that the sleeve can drive the mixing drum to rotate, and through the first transmission component, the sleeve can drive the mixing drum to rotate while driving the mixing drum to rotate, and through the first transmission component, the stirring blade body can be driven to rotate when the sleeve drives the mixing drum to rotate, and then a better stirring effect can be achieved through multi-directional rotation, so that before adding vitrified microspheres in the preparation of thermal insulation mortar, the raw materials can be quickly stirred evenly, the efficiency is improved, and the quality of the thermal insulation mortar is guaranteed;

[0021] 2. In the present invention, a stirring barrel shaft is provided, and a retractable stirring blade body is provided on the stirring barrel shaft. Through the cooperation of the stirring blade body and the first shaft rod, the stirring blade body can be driven to retract and extend during the rotation process, so that the stirring blade body can bring the vitrified micro-beads into the stirring barrel while stirring, and the second electric push rod drives the movement of the stirring barrel shaft to bring the vitrified micro-beads to different positions of the stirring barrel for stirring, so that the vitrified micro-beads can be more evenly distributed in the thermal insulation mortar, thereby ensuring the quality of the thermal insulation mortar;

[0022] 3. In the present invention, a first shaft is provided, and the first shaft and the mixing barrel shaft are driven to rotate in opposite directions by the second transmission component. Due to the unidirectional swinging effect of the mixing blade body, when the mixing barrel shaft rotates counterclockwise, the lever on the first shaft cooperates with the lever plate on the mixing blade body to push the mixing blade body to extend all the time, so that the mixing blade body is kept in a state of stirring all the time, thereby providing a thorough stirring effect for the thermal insulation mortar before the vitrified microspheres are put in. When the mixing barrel shaft rotates clockwise, the first shaft lever shifts the lever plate on the mixing blade body, and drives the mixing blade body to retract and extend under the maximum use of the torsion spring. The vitrified microspheres can be brought out of the mixing barrel shaft by the action of the piston body and the second spring in the mixing blade body, thereby completing the stirring and bringing the vitrified microspheres into the mixing barrel. The structure is ingenious, and different working modes can be changed according to different working states.

[0023] 4. In the present invention, by setting the first slide plate and the first spring, when adding vitrified microspheres to the mixing barrel shaft, the opening of the mixing barrel shaft faces upward, and the vitrified microspheres push the first slide plate to overcome the first spring and move downward by their own gravity. When the vitrified microspheres need to be added to the thermal insulation mortar, the opening of the mixing barrel shaft faces downward, and the first spring pushes the first slide plate to give the vitrified microspheres an outward thrust, thereby ensuring that the vitrified microspheres can be added to the thermal insulation mortar.

[0024] 5. In the present invention, by arranging a piston plate in the mixing drum and controlling the extension and retraction of the stirring blade body, when material needs to be unloaded, the stirring blade body is controlled to retract, driving the mixing drum axis to move outward. When the stirring blade body comes to the outside of the piston plate, the stirring blade body is controlled to extend to clamp the piston plate, and then the mixing drum axis is controlled to move inward to drive the piston plate to follow the movement. Not only can the thermal insulation mortar in the mixing drum be quickly pushed out, but also the inside of the mixing drum can be scraped clean, thereby improving efficiency and saving manpower.

[0039] The stirring blade assembly includes a stirring blade body 71, a side wall of the stirring barrel shaft 31 is provided with a notch 3a, the stirring blade body 71 is arranged at the notch 3a through a hinge shaft 7a, a limiting protrusion 712 is provided on the stirring blade body 71, a torsion spring 72 is sleeved on the hinge shaft 7a, and the torsion spring 72 is used to force the stirring blade body 71 to rotate outward from the notch 3a, when the stirring blade body 71 is completely rotated outward from the notch 3a, the limiting protrusion 712 abuts against the inner side wall of the stirring barrel shaft 31; the stirring blade body 71 is provided with a paddle 711 extending into the stirring barrel shaft 31, and one end of the first shaft rod 51 extending into the stirring barrel shaft 31 is provided with a plurality of paddle rods 511 corresponding to the stirring blade body 71 one by one. When the first shaft rotates, the lever 511 drives the stirring blade body 71 through the lever plate 711 to rotate into the stirring barrel shaft 31 from the slot 3a. When the lever 511 is disengaged from the lever plate 711, the torsion spring 72 forces the stirring blade body 71 to extend outward from the slot 3a to the stirring barrel shaft 31.

[0040] Each stirring blade body 71 is provided with a radial groove 7b and a piston hole 7c connected to the radial groove 7b along the radial direction of the hinge shaft 7a. A piston body 731 is slidably connected in the radial groove 7b. The piston body 731 is provided with a protrusion 73 extending into the piston hole 7c. The radial groove 7b is provided with a second spring 74 for forcing the piston body 731 to drive the protrusion 73 to extend into the piston hole 7c. After the vitrified microspheres are installed in the stirring barrel shaft 31, as the stirring blade body 71 is screwed into the stirring barrel shaft 31, the vitrified microspheres enter the piston hole 7c and push the piston body 731 to compress the second spring 74 through the protrusion 73. When the stirring blade body 71 is screwed out of the stirring barrel shaft 31 from the notch 3a, the protrusion 73 pushes the vitrified microspheres into the stirring barrel 21.

[0041] In the above S1 of this embodiment, the first motor 13 is used to control the mixing drum 21 to rotate to the opening upward position; a proper amount of glass beads are added to the mixing drum shaft 31, and the gravity of the glass beads themselves can push the first slide plate 33 to overcome the first spring 34 and move downward.

[0042] In the above S2 of the present embodiment, when the first stirring component and the second stirring component are controlled to stir the raw materials for preparing the thermal insulation mortar except the vitrified microspheres in the mixing drum 21, the first electric push rod 14 is controlled to extend to drive the mixing drum 21 to rise, and the first motor 13 is started to drive the sleeve 15 to rotate. Since the first bevel gear 61 is fixedly connected to the first frame 12, and the first bevel gear 61 is respectively meshed with the upper bevel gear 62 and the lower bevel gear 63, the upper bevel gear 62 is fixedly connected to the mixing drum 21, and the lower bevel gear 63 is fixedly connected to the connecting frame 42, the connecting frame 42 is rotated with the mixing drum 21, so that the sleeve 15 drives the mixing drum 21 to rotate when rotating, and at the same time drives the connecting frame 42 to rotate around the mixing drum 21, and the rotation direction is opposite to the rotation direction of the mixing drum 21. At the same time, the second motor 44 is controlled to rotate to drive the second bevel gear 45 to rotate. Since the second bevel gear 45 is respectively meshed with the third bevel gear 52 and the fourth bevel gear 35, the mixing barrel shaft 31 is driven to rotate counterclockwise ( Figure 7 Since the fourth bevel gear 35 and the third bevel gear 52 rotate in opposite directions, the first shaft 51 rotates clockwise ( Figure 7 The lever 511 is driven to push the plate 711, so that the stirring blade body 71 is rotated out of the notch 3a. Due to the positioning of the limiting protrusion 712, the stirring blade body 71 is positioned at the extended position, and then the second motor 44 is stopped, and the lever 511 is kept at the brake pad of the second motor 44. Figure 7 In the position shown, at this time, since the second bevel gear 45 does not rotate, the connecting frame 42 rotates, which drives the mixing barrel shaft 31 to rotate, and then drives the mixing blade body 71 to mix the raw materials in the mixing drum 21, and at the same time controls the second electric push rod 43 to extend and retract, so as to achieve the purpose of uniform mixing and complete rapid mixing.

[0043] In the above S3 of this embodiment, when the second stirring component is controlled to add the vitrified microspheres into the stirring drum 21 and slowly stir, the first motor 13 is controlled to rotate so that the stirring drum 21 stops at a position where the outer cover 22 is facing downward, and then the first electric push rod 14 is controlled to contract to drive the stirring drum 21 to descend. At this time, the inner cover 32 on the stirring drum shaft 31 is also facing downward, and the first spring 34 pushes the first slide plate 33 downward to give the vitrified microspheres in the stirring drum shaft 31 a thrust to move outward, and then the second motor 44 is started to drive the second bevel gear 45 to rotate, thereby driving the stirring drum shaft 31 to rotate clockwise ( Figure 6 Since the first shaft 51 and the mixing barrel shaft 31 rotate in opposite directions, the lever 511 pushes the lever plate 711 to drive the mixing blade body 71 to overcome the torsion spring 72 and rotate, so that the mixing blade body 71 is retracted into the mixing barrel shaft 31 (such as Figure 5 As shown, since the vitrified microspheres are acted upon by the first spring 34, the vitrified microspheres push the piston body 731 through the protrusion 73 to overcome the second spring 74 and enter the piston hole 7c in the stirring blade body 71. When the lever 511 passes over the lever plate 711, the stirring blade body 71 rotates outward under the action of the torsion spring 72, and the protrusion 73 is pushed out under the action of the second spring 74, bringing the vitrified microspheres into the mixing drum 21. By controlling the second electric push rod 43 to continuously extend and retract, the second motor 44 can continuously rotate, so that the mixing drum shaft 31 continuously rotates to drive the stirring blade body 71 to perform slow stirring, while adding the vitrified microspheres little by little to different positions in the mixing drum 21, which is more conducive to the uniform distribution of the vitrified microspheres and completes the preparation of the thermal insulation mortar.

[0044] In the above S4 of this embodiment, when the second stirring assembly is controlled to cooperate with the first stirring assembly to push out the thermal insulation mortar in the stirring drum 21, the second motor 44 is controlled to drive the stirring drum shaft 31 and the first shaft 51 to rotate, so that the stirring blade body 71 stops in a fully retracted state (such as Figure 5 As shown), the second electric push rod 43 is controlled to extend to drive the mixing drum shaft 31 to move upward. When the mixing blade body 71 is completely above the piston plate 23, the second motor 44 is controlled to rotate to extend the mixing blade body 71 and clamp the piston plate 23 between the mixing blade body 71 and the inner cover 32. The outer cover 22 is then opened, and the thermal insulation mortar falls into the collecting tank 111. At the same time, the second electric push rod 43 is controlled to contract to drive the piston plate 23 to descend, push out the thermal insulation mortar in the mixing drum 21, and scrape off the thermal insulation mortar adhered to the inner wall of the mixing drum 21 to complete the cleaning, save manpower, and then complete automatic unloading and internal cleaning.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
