[0002] Thermal insulation mortar is a premixed dry powder mortar made by mixing various lightweight materials as aggregates, cement as binder, and some modified additives. It is a building material used to construct the thermal insulation layer on the building surface. Inorganic thermal insulation mortar materials are fireproof and non-combustible, and can be widely used in dense residential buildings, public buildings, large public places, flammable and explosive places, and places with strict fire protection requirements. It can also be used as a fire isolation zone to improve the fire protection standards of buildings.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0026] Example: Figure 1-6 As shown, this utility model discloses a mixing device for producing thermal insulation mortar, including a shell 1, a mixing tank 101 inside the shell 1, a support frame 2 fixedly welded to the top of the shell 1, a drive motor 3 bolted to the top of the support frame 2, a reciprocating screw 4 connected to the output end of the drive motor 3, a threaded plate 5 threaded to the outer circumference of the reciprocating screw 4, a power motor 6 fixedly connected to the top side of the threaded plate 5, a rotating shaft 7 connected to the output end of the power motor 6 through the threaded plate 5, and several mixing blades 8 fixedly welded to the outer circumference of the rotating shaft 7.
[0027] The top of the rotating shaft 7 is fixedly connected to a mixing plate 9. The surface of the mixing plate 9 is provided with a groove 10. Scrapers 11 are fixedly welded to both ends of the mixing plate 9. A brush 12 is fixedly connected to the bottom of the mixing plate 9. By setting the scraper 11, the thermal insulation mortar raw material on the inner wall of the mixing tank 101 can be fully mixed during mixing. After mixing, the residue on the inner wall of the mixing tank 101 can also be scraped and cleaned to avoid affecting the quality of the next mixing process.
[0028] The mixing tank 101 is fixedly connected to the outer periphery of the slide rail 13, and the inner wall of the outer shell 1 is provided with a slide groove 14. The slide rail 13 is slidably connected to the slide groove 14. By setting the slide rail 13, the mixing tank 101 is limited, so that the mixing tank 101 can rotate inside the outer shell 1.
[0029] The bottom of the mixing tank 101 is fixedly connected to a discharge pipe 15, and a worm gear 16 is fixedly welded to the outside of the discharge pipe 15. A servo motor 17 is fixedly installed on the outer periphery of the outer shell 1. The output end of the servo motor 17 is driven by a worm gear 18, and the worm gear 16 is driven by the worm gear 18. By setting the worm gear 18, the rotation of the worm gear 18 drives the mixing tank 101 to rotate, which is opposite to the rotation of the mixing blades 8 inside the mixing tank 101. This greatly enhances the mixing rate of the thermal insulation mortar raw materials and improves the mixing effect of the thermal insulation mortar raw materials.
[0030] The outer shell 1 is fitted with a screw feeder 19. One end of the screw feeder 19 is fixedly connected to a micro motor 20, and the top end of the screw feeder 19 is fixedly connected to a material inlet 21. By setting the screw feeder 19, the thermal insulation mortar that has been mixed in the mixing tank 101 can be continuously and stably transported.
[0031] The output end of the micro motor 20 is connected to the screw feeder 19 via a screw feeder shaft 25. The screw feeder shaft 25 is fixedly welded to the outer periphery of the screw feeder shaft 25. The lower end of one side of the screw feeder 19 is fixedly connected to the discharge port 23. By setting the screw feeder 19, the thermal insulation mortar can be conveyed at the same time. The screw feeder 19 is in a closed form, which helps to prevent the thermal insulation mortar from contacting dust in the air and improves the quality of the thermal insulation mortar.
[0032] The bottom of the outer casing 1 is provided with four support rods 24. The support rods 24 are fixedly connected to the bottom of the outer casing 1 in a rectangular array. By setting the support rods 24, the outer casing 1 can be placed safely and stably, improving the air circulation efficiency inside the outer casing 1 and enhancing the heat dissipation effect.
[0033] The bottom of the mixing tank 101 is arc-shaped, and the diameter of the receiving port 21 is larger than the diameter of the discharge pipe 15. By setting the diameter of the receiving port 21 to be larger than the diameter of the discharge pipe 15, the discharge pipe 15 can move inside the receiving port 21, preventing damage to the device when the discharge pipe 15 rotates.
[0034] Working Principle: During use, the thermal insulation mortar raw materials to be mixed are placed into the mixing drum 101. Simultaneously, the drive motor 3, power motor 6, and servo motor 17 are started. The output of the drive motor 3 drives the reciprocating screw 4 to rotate, causing the threaded plate 5 to move up and down reciprocally. The output of the power motor 6 drives the rotating shaft 7 to rotate, causing the mixing blades 8 to fully mix the thermal insulation mortar raw materials in the mixing drum 101. Simultaneously, the mixing plate 9 is also driven to mix, preventing the raw materials from settling at the bottom of the mixing drum 101 and thus increasing the mixing speed. During mixing, the scraper 11 can fully mix the thermal insulation mortar raw materials on the inner wall of the mixing drum 101. After mixing, residues on the inner wall of the mixing drum 101 can be scraped and cleaned to avoid affecting the quality of the next mixing process. The threaded plate 5 drives the mixing blades 8 within the mixing drum 101... The reciprocating motion of the mixing unit enables stirring at different locations, increasing the stirring area and effectively improving the stirring efficiency. The output of the servo motor 17 drives the worm gear 18 to rotate, which in turn drives the mixing tank 101 to rotate via the worm wheel 16. This rotation is opposite to the rotation of the stirring blades 8 inside the mixing tank 101, greatly enhancing the stirring rate of the thermal insulation mortar raw materials and improving the stirring effect. After the thermal insulation mortar is stirred, the micro motor 20 is started to drive the spiral feeding shaft 25 to rotate. Through the spiral feeding blades 22, the thermal insulation mortar stirred in the mixing tank 101 can be continuously and stably conveyed. The spiral feeder 19 is enclosed, which helps to prevent the thermal insulation mortar from contacting dust in the air, improving the quality of the thermal insulation mortar. After the thermal insulation mortar is stirred, it is finally discharged quickly from the discharge port 23.
