Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a self-insulating building block material mixing device. Background Art

[0002] Self-insulating blocks are a new type of wall material that can meet people's needs in terms of thermal insulation, heat insulation, and environmental protection. At the same time, they need to follow a certain formula during the production process. Different raw materials and different formulas can produce self-insulating blocks with different performances. Commonly used self-insulating block process formulas include formulas based on bubble ceramsite, perlite, expanded perlite, and siliceous sand, as well as formulas such as magnesia sand, bentonite, and expanded clay.

[0003] Since the raw materials of self-insulating blocks are relatively viscous, the mixer may stick to the wall. In many patent documents, the solution to the problem of wall sticking is to install a scraper on the stirring shaft. As the stirring shaft rotates, the scraper continuously scrapes the inner wall of the mixing bin to avoid sticking. Although this method is simple and has a good cleaning effect, it has disadvantages. First, it increases the resistance to the rotation of the stirring shaft, resulting in increased power consumption. Second, the scraper continues to rub against the inner wall of the mixing bin and will soon become ineffective. Utility Model Content

[0004] In order to solve the problems mentioned in the background technology, the purpose of the present invention is to provide a self-insulating building block material mixing device.

[0005] In order to achieve the above objectives, the technical solution of the utility model is:

[0006] A self-insulating block material mixing device comprises a mixing tank, a stirring shaft, a valve, a motor, a crossbeam, a lifting mechanism, a first ring, a second ring and a plurality of scraping strips, wherein a valve is installed at the bottom of the mixing tank, the stirring shaft is longitudinally arranged in the mixing tank, a plurality of stirring blades are fixed on the stirring shaft, the top of the stirring shaft is connected to the motor, the crossbeam is fixed to the top of the mixing tank, a lifting mechanism is installed on the crossbeam, the motor is fixed to the lifting end of the lifting mechanism, the scraping strips are attached to the inner wall of the mixing tank and the plurality of scraping strips are attached to the inner wall of the mixing tank. The wall strips are arranged at intervals along the circumference of the mixing tank. The ring one is movably sleeved on the outside of the stirring shaft. A plurality of connecting arms are circumferentially arranged on the ring one, and the plurality of connecting arms are respectively fixedly connected to a plurality of scraping strips. The ring two is fixedly sleeved on the stirring shaft and is arranged above the ring one. A column is longitudinally fixed to the bottom of the ring two, and the column is arranged on the periphery of the ring one. When the lifting mechanism rises to the top, the height of the bottom of the column is higher than the connecting arm. When the lifting mechanism falls to the lowest point, the height of the bottom of the column is lower than the connecting arm.

[0007] Furthermore, the number of the columns corresponds to the number of the connecting arms, and a plurality of the columns are arranged at intervals in the circumferential direction of the ring 2.

[0008] Furthermore, the lifting mechanism includes a mounting seat and two telescopic cylinders, the cylinder bodies of the two telescopic cylinders are longitudinally fixed on the crossbeam, the piston rods of the two telescopic cylinders are commonly mounted with a mounting seat, and the motor is fixed on the mounting seat.

[0009] The beneficial effects of the present invention are as follows: the height of the stirring shaft can be adjusted by the lifting mechanism, thereby changing the height of the column, thereby realizing the linkage or separation of the scraper bar and the stirring shaft. When mixing, the height of the bottom of the column is made higher than the connecting arm. At this time, only the stirring shaft rotates to mix the materials, and it has the function of a conventional mixer; when the inner wall of the mixing tank needs to be cleaned, the height of the bottom of the column is made lower than the connecting arm. When the stirring shaft rotates, the column will touch the connecting arm and push the connecting arm to rotate, thereby allowing multiple scraper bars to clean the inner wall of the mixing tank, and it has the function of cleaning the inner wall of the mixing tank. This device will neither increase the resistance of the stirring shaft during mixing, nor allow the scraper bar to rub against the inner wall of the mixing tank for a long time, and can be used for a long time.

Obviously, the embodiments described 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 are within the scope of protection of the present invention.

[0015] like Figure 1-Figure 3As shown, a self-insulating block material mixing device includes a mixing tank 1, a stirring shaft 2, a valve 3, a motor 4, a crossbeam 5, a lifting mechanism, a ring 1 6, a ring 2 7 and three scraping strips 62. The lower part of the mixing tank 1 is conical and a valve 3 is installed at the tip of the cone. The stirring shaft 2 is coaxially arranged in the mixing tank 1. A plurality of stirring blades 21 are fixed to the stirring shaft 2. The top of the stirring shaft 2 is connected to the main shaft of the motor 4 through a coupling. The crossbeam 5 is fixed to the top of the mixing tank 1. A lifting mechanism is installed on the crossbeam 5. The motor 4 is fixed to the lifting end of the lifting mechanism. Preferably, the lifting mechanism includes a mounting seat 9 and two telescopic cylinders 8. The cylinder bodies of the two telescopic cylinders 8 are longitudinally fixed on the crossbeam 5. The piston rods of the two telescopic cylinders 8 are jointly equipped with a mounting seat 9. 4 is fixed on the mounting seat 9, the scraping strips 62 are attached to the inner wall of the mixing tank 1 and the three scraping strips 62 are evenly arranged along the circumference of the mixing tank 1, the ring 1 6 is movably sleeved on the outside of the stirring shaft 2, and three connecting arms 61 are circumferentially arranged on the ring 1 6, the connecting arms 61 are arranged horizontally, and the three connecting arms 61 are respectively fixed to the three scraping strips 62, the ring 2 7 is fixedly sleeved on the stirring shaft 2 and the ring 2 7 is arranged above the ring 1 6, and three columns 71 are longitudinally fixed to the bottom of the ring 2 7, the columns 71 are arranged on the periphery of the ring 1 6, and the three main bodies are evenly arranged around the circumference of the ring 2 7, when the mounting seat 9 is raised to the top, the height of the bottom of the columns 71 is higher than the connecting arms 61, and when the mounting seat 9 is lowered to the lowest point, the height of the bottom of the columns 71 is lower than the connecting arms 61.

[0016] In actual use, the height of the stirring shaft 2 can be adjusted by the telescopic cylinder 8, thereby changing the height of the column 71, thereby realizing the linkage or separation of the scraper bar 62 and the stirring shaft 2.
