Description

Technical Field

[0001] This application relates to the field of mixing devices, and in particular to a mixing device for raw materials used in the construction of thermal insulation layers. Background Technology

[0002] During the construction of the insulation layer, raw material mixing is a crucial step in ensuring the performance of the insulation layer. Currently, the common method for mixing insulation layer raw materials is to use a mixing drum with a mixing paddle. During construction, raw materials such as insulation mortar, binder, and lightweight aggregate are put into the mixing drum, and the rotation of the mixing paddle ensures that the raw materials are mixed evenly, providing a qualified mixture for subsequent insulation layer construction.

[0003] However, during the mixing process, some raw materials adhere to and solidify on the inner wall of the mixing tank. As the mixing operation continues, the thickness of the adhered raw materials gradually increases. Currently, the removal of these adhered raw materials mainly relies on manual operation. Construction workers need to use tools such as scrapers to scrape and clean the tank wall. This process not only consumes a lot of time and manpower, interrupts the mixing process, and reduces the mixing efficiency of raw materials, but may also cause residual raw materials to be mixed into the raw materials to be mixed later due to incomplete manual cleaning, affecting the accuracy of the ratio of the insulation layer raw materials, and ultimately having an adverse effect on the construction quality and insulation performance of the insulation layer.

[0004] In view of the above-mentioned related technologies, the inventors believe that there is a defect in the material of the insulation layer adhering to the inner wall of the mixing tank during the mixing process. Therefore, a material mixing device for insulation layer construction is proposed to solve the above problems. Utility Model Content

[0005] To address the issue of material adhesion to the inner wall of the mixing drum during the mixing process of insulation layer raw materials, this application provides a raw material mixing device for insulation layer construction.

[0006] The technical solution of the raw material mixing device for thermal insulation layer construction provided in this application is as follows:

[0007] A material mixing device for thermal insulation layer construction includes a mixing drum. A discharge port is provided at the bottom of one side of the outer surface of the mixing drum. A drive motor is installed below the mixing drum. The output end of the drive motor extends into the mixing drum and is fitted with a support shaft. Several mixing rods are fixedly connected to the outer surface of the support shaft. A spline shaft is fixedly installed at the middle of the top end of the support shaft. A fixing frame is fixedly installed at the middle of the top end of the mixing drum. A movable support plate is rotatably installed at the middle of the top end of the inner wall of the fixing frame via a bearing. Several fixing rods are fixedly connected to the bottom edge of the movable support plate. Several scraper plates are welded to one side of the outer surface of the fixing rods. A connecting mechanism is also provided at the middle of the bottom end of the movable support plate for controlling the movable support plate to rotate synchronously with the support shaft.

[0008] Preferably, the connecting mechanism includes a plurality of hollow tubes, which are fixedly installed at equal intervals at the bottom center of the movable support plate. A movable support rod is movably installed at the bottom center of the hollow tube. An elastic damping block is installed at the top center of the movable support rod inside the hollow tube. A connecting plate is fixedly installed at the bottom end of the plurality of movable support rods, and a spline sleeve is fixedly connected to the bottom center of the connecting plate.

[0009] Preferably, there is a certain gap between two adjacent scraper blades, and multiple scraper blades on two adjacent fixed rods are arranged in an alternating vertical arrangement, with one side of each scraper blade close to the inner wall of the mixing tank.

[0010] Preferably, a spline groove is formed in the middle of the bottom end of the spline sleeve, the top of the spline shaft is located inside the spline groove, and the spline shaft and the spline sleeve are engaged with each other.

[0011] Preferably, the outer diameter of the movable support rod is smaller than the inner diameter of the bottom opening of the hollow tube, the outer diameter of the elastic damping block is larger than the inner diameter of the bottom opening of the hollow tube, and the outer surface of the elastic damping block abuts against the inner wall of the hollow tube.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The drive motor rotates the support shaft and stirring rod to mix the raw materials. The connecting mechanism allows the movable support plate to rotate synchronously, while the fixed rod and scraper clean the raw materials adhering to the barrel wall. This eliminates the need for manual interruption of cleaning, improving mixing efficiency. The staggered arrangement of the scrapers covers the barrel wall for more thorough cleaning, ensuring accurate raw material proportions and improving the quality of insulation layer construction.

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a raw material mixing device for thermal insulation layer construction. (Refer to...) Figure 1-3 A material mixing device for thermal insulation layer construction includes a mixing tank 1. A discharge port 2 is provided at the bottom of one side of the outer surface of the mixing tank 1. A drive motor 3 is installed below the mixing tank 1. The output end of the drive motor 3 extends into the mixing tank 1 and a support shaft 4 is installed. Several mixing rods 5 are fixed to the outer surface of the support shaft 4. A spline shaft 6 is fixedly installed at the middle of the top of the support shaft 4. A fixing frame 7 is fixedly installed at the middle of the top of the mixing tank 1. A movable support plate 8 is rotatably installed at the middle of the top of the inner wall of the fixing frame 7 through a bearing. Several fixing rods 9 are fixed to the bottom edge of the movable support plate 8. Several scraper plates 10 are welded to one side of the outer surface of the fixing rods 9. There is a certain distance between two adjacent scraper plates 10. The multiple scraper plates 10 on two adjacent fixing rods 9 are arranged in an alternating vertical arrangement. One side of the scraper plate 10 is close to the inner wall of the mixing tank 1. A connecting mechanism is also provided at the middle of the bottom of the movable support plate 8 to control the movable support plate 8 to rotate synchronously with the support shaft 4.

[0020] By starting the drive motor 3, power is output to rotate the support shaft 4, and the stirring rod 5 stirs the insulation layer material. At the same time, the fixed rod 9 rotates with the movable support plate 8, causing the scraper 10 to move against the inner wall of the mixing tank 1 to remove the adhering material. Adjacent scraper plates 10 are staggered to fully cover the tank wall and ensure thorough cleaning.

[0021] Reference Figure 2 and Figure 3 The connecting mechanism includes several hollow tubes 11, which are equidistantly fixedly installed at the bottom center of the movable support plate 8. A movable support rod 12 is movably installed at the bottom center of the hollow tube 11. An elastic damping block 13 is installed at the top center of the movable support rod 12 inside the hollow tube 11. The outer diameter of the movable support rod 12 is smaller than the inner diameter of the bottom opening of the hollow tube 11, and the outer diameter of the elastic damping block 13 is larger than the inner diameter of the bottom opening of the hollow tube 11. The outer surface of the elastic damping block 13 abuts against the inner wall of the hollow tube 11. A connecting plate 14 is fixedly installed at the bottom of the multiple movable support rods 12. A spline sleeve 15 is fixedly connected at the bottom center of the connecting plate 14. A spline groove is opened at the bottom center of the spline sleeve 15. The top of the spline shaft 6 is located inside the spline groove. The spline shaft 6 and the spline sleeve 15 are engaged with each other.

[0022] The movable support plate 8 is rotated synchronously by driving the connecting plate 14 and the movable support rod 12, so that the spline sleeve 15 is fitted on the outer surface of the spline shaft 6, and the elastic damping block 13 is buffered in the hollow tube 11 to maintain the stability of the movable support rod 12.

[0023] The implementation principle of the raw material mixing device for thermal insulation layer construction in this embodiment is as follows: When the device is working, the drive motor 3 is started to output power, driving the support shaft 4 to rotate. The mixing rod 5 mixes the thermal insulation layer raw material. At the same time, the spline shaft 6 at the top of the support shaft 4 cooperates with the spline sleeve 15 to drive the connecting plate 14 and the movable support rod 12 to make the movable support plate 8 rotate synchronously. The fixed rod 9 rotates with the movable support plate 8, driving the scraper 10 to move against the inner wall of the mixing tank 1 to remove the adhering raw material. Adjacent scraper plates 10 are staggered to fully cover the tank wall and ensure thorough cleaning. The elastic damping block 13 buffers inside the hollow tube 11 to maintain the stability of the movable support rod 12, ensuring reliable operation of the connecting mechanism, realizing simultaneous mixing and cleaning, and improving mixing efficiency and the quality of thermal insulation layer raw material.
