Description

Technical Field

[0001] This disclosure specifically discloses a mortar processing technology field, specifically relating to a double-helix high-efficiency mortar discharge equipment. Background Technology

[0002] Concrete walls are made by pouring mortar. Before pouring mortar, it is necessary to mix the different components in the mortar. Existing mortar mixing machinery cannot achieve automatic conveying of mortar raw materials and has a complex structure, making it inconvenient to use. Currently, in construction, a mixing tank is usually used for rolling mixing, which is a batching equipment used for bulk cement storage in mixing plants.

[0003] According to application number 201721342587.X, a bidirectional stirring and anti-settling building mortar mixing and discharging tank is disclosed, including a discharge hopper, a mixing tank, a uniform material tray, a feeding rod, a buffer hopper, and a spiral guide rib. A frame is welded to the bottom of the mixing tank, and a tank cover is connected to the top of the mixing tank. A motor is installed in the center of the top of the tank cover, and the motor is connected to a rotating shaft. A uniform material tray is located below the feeding rod and is welded to the inner wall of the mixing tank. The uniform material tray has several material distribution holes. The mixing tank is equipped with a discharge hopper at the bottom, and the discharge hopper is provided with a spiral guide rib. When the discharge hopper rotates counterclockwise, the mortar in the spiral guide groove slides upward and outward under the stirring of the spiral guide rib, avoiding mortar deposition. When the discharge hopper rotates clockwise, the mortar in the spiral guide groove slides downward and inward under the stirring of the spiral guide rib. The mortar in the spiral guide groove moves to the discharge pipe and is quickly discharged, avoiding sludge accumulation and blockage, and improving the efficiency of mortar discharge.

[0004] Existing mortar discharge devices are equipped with simple mixing devices. The mixing rod cannot withstand the impact of some large particles in the mortar, which shortens the service life of the mixing rod. In addition, the discharge port of the existing mortar discharge devices is not equipped with a discharge device, resulting in a large amount of mortar accumulating at the discharge port and affecting the discharge efficiency. Therefore, we propose a double-helix high-efficiency mortar discharge device. Summary of the Invention

[0022] As mentioned in the background section, existing mortar discharge devices are equipped with simple mixing devices. The mixing rod cannot withstand the impact of some large particles in the mortar, which shortens the service life of the mixing rod. In addition, the discharge port of the existing mortar discharge device is not equipped with a discharge device, resulting in a large amount of mortar accumulating at the discharge port and affecting the discharge efficiency. This disclosure proposes a structure with spiral mixing and spiral discharge. Example 1

[0023] Please see Figure 1 The double-helix high-efficiency mortar discharge device includes a mixing tank 1, which is funnel-shaped. To ensure normal discharge of the mixing tank 1, a discharge pipe 4 is fixedly connected to the lower end face of the mixing tank 1. A sealing plate 5 is movably connected to the lower end face of the discharge pipe 4. The sealing plate 5 can prevent mortar leakage. To ensure that the sealing plate 5 can be easily disassembled, limit devices 6 are fixedly connected to both the left and right sides of the outer wall of the sealing plate 5 to ensure that the sealing plate 5 will not fall off. To facilitate the removal of mortar, support columns 2 are evenly fixedly connected to the lower part of the outer wall of the mixing tank 1.

[0024] Please see Figure 1In order to facilitate the addition of mortar powder and sand to the inner cavity of the mixing tank 1, a feed inlet 7 is fixedly connected to the left side of the upper end face of the mixing tank 1, and the feed inlet 7 is connected to the mixing tank 1. In order to fully mix the mortar powder and sand, a stirring device 8 is provided in the middle of the inner cavity of the mixing tank 1.

[0025] Please see Figure 2 To ensure that the sealing plate 5 can be installed on the lower end face of the discharge pipe 4 and can be quickly disassembled, a limiting device 6 is formed by limiting block 61, limiting opening 62 and connecting seat 63. Connecting seats 63 are fixedly connected to both sides of the outer wall of the sealing plate 5, and the upper end face of the connecting seat 63 is higher than the upper end face of the sealing plate 5. Limiting openings 62 are opened in the middle of the opposite face of the connecting seat 63. Limiting blocks 61 are fixedly connected to both sides of the lower part of the outer wall of the discharge pipe 4, and the limiting blocks 61 are installed in the inner cavity of the limiting opening 62. The limiting opening 62 matches the limiting block 61.

[0026] Please see Figure 2 To ensure thorough mixing of mortar powder and sand within the mixing tank 1, a mixing device 8 is constructed, consisting of a drive motor 81, a rotating shaft 82, connecting columns 83, and a mixing impeller 84. The drive motor 81 is fixedly connected to the center of the upper surface of the mixing tank 1, and the motor shaft of the drive motor 81 extends through the inner cavity of the mixing tank 1 and is fixedly connected to the rotating shaft 82. The mixing impeller 84 is sleeved on the outside of the rotating shaft 82. To fix the mixing impeller 84, connecting columns 83 are evenly fixedly connected to the outer wall of the rotating shaft 82, and the ends of the connecting columns 83 are fixedly connected to the mixing impeller 84. The stability of the mixing impeller 84 is effectively ensured by connecting several connecting columns 83.

[0027] Please see Figure 2 In order to improve mixing efficiency and withstand the impact of larger particles, the mixing impeller 84 extends downward in a spiral shape. The mixing impeller 84 can mix the mortar and drive the mortar downward.

[0028] Please see Figure 3 In order to ensure normal material discharge from the mixing tank 1 and to prevent mortar from accumulating inside the discharge pipe 4, a fixed shaft 10 is fixedly connected to the bottom end face of the rotating shaft 82, and a spiral blade 11 is movably connected to the outer wall of the fixed shaft 10. The end of the fixed shaft 10 extends to the bottom of the inner cavity of the discharge pipe 4, and the diameter of the spiral blade 11 matches the inner diameter of the discharge pipe 4. Example 2

[0029] Please see Figure 1 To ensure the stability of the mixing tank 1, three sets of support columns 2 are provided, and the three sets of support columns 2 are arranged in a ring array on the outer wall of the middle part of the mixing tank 1. The lower end face of each support column 2 is fixedly connected to a flange 3, which can be connected to the ground by bolts, thereby ensuring the stability of the mixing roller 1.

[0030] Working principle: When in use, place the sealing plate 5 at the lower end of the discharge pipe 4, ensuring that the limiting block 61 is inserted into the limiting opening 62, effectively ensuring the stability of the sealing plate 5. The operator pours the powder and sand into the feed inlet 7, connects to an external power source, and starts the drive motor 81. The drive motor 81 drives the rotating shaft 82 to rotate, and the rotating shaft 82 drives the connecting column 83 and the stirring impeller 84 to rotate. The powder and sand are fully mixed by the rotation of the connecting column 83 and the stirring impeller 84. After the mixing is completed, remove the sealing plate 5. The rotating shaft 82 drives the fixed shaft 10 to rotate, and the fixed shaft 10 drives the spiral blade 11 to rotate. The spiral blade 11 rotates to discharge the mortar.
