[0025] This utility model proposes a mixing and storage tank and an automatic grouting device, aiming to solve the problems of poor slurry mixing effect and low operation efficiency of existing mixing and storage tanks and automatic grouting devices.
[0026] See Figure 1 and Figure 2 This embodiment provides a mixing and storage tank, including a tank body 1 and a mixing assembly 2. The tank body 1 forms a cavity 1.1. The tank body 1 has a slurry filling port 1.2 and a slurry discharge port. The slurry filling port 1.2 is connected between the cavity 1.1 and the pulping machine. The slurry discharge port is connected between the cavity 1.1 and the slurry pump. The bottom wall of the cavity 1.1 is inclined towards the slurry discharge port. The mixing assembly 2 includes a mixing drive 2.1 and a mixing paddle 2.2. The mixing drive 2.1 is disposed on the tank body 1. The first end of the mixing paddle 2.2 is connected to the output end of the mixing drive 2.1, and the second end is disposed opposite to the center of the bottom wall of the cavity 1.1. The mixing paddle 2.2 is perpendicular to the bottom wall of the cavity 1.1. In this embodiment, the bottom wall of the cavity 1.1 is inclined to ensure that the slurry in the cavity 1.1 can flow smoothly to the slurry outlet, thereby ensuring the efficiency of the grouting operation. Under the action of the stirring drive 2.1, the stirring paddle 2.2 stirs the slurry in the cavity 1.1. The second end of the stirring paddle 2.2 is set directly opposite the center of the bottom wall of the cavity 1.1, and the stirring paddle 2.2 is perpendicular to the bottom wall of the cavity 1.1, which can effectively avoid uneven stirring and thus improve the stirring effect of the slurry.
[0027] The mixing paddle 2.2 includes a mixing shaft 2.2.1 and multiple mixing blades 2.2.3. The first end of the mixing shaft 2.2.1 is connected to the output end of the mixing drive 2.1. The multiple mixing blades 2.2.3 are spaced apart along the extension direction of the mixing shaft 2.2.1. The first end of each mixing blade 2.2.3 is inclined on the mixing shaft 2.2.1, and the second end extends in a direction perpendicular to the mixing shaft 2.2.1. The inclination angle of each mixing blade 2.2.3 is different. When the mixing paddle 2.2 mixes the slurry in the cavity 1.1 under the action of the mixing drive 2.1, the different inclination angles of each mixing blade 2.2.3 ensure that the flow state of the cement slurry in the tank 1 is a transitional flow state, effectively preventing slurry segregation, ensuring sufficient mixing of the slurry, and improving the quality of the grouting slurry.
[0028] Specifically, a recess is formed at the center of the bottom wall of the cavity 1.1, and the second end of the stirring shaft 2.2.1 is movably disposed in the recess. The recess can limit the second end of the stirring shaft 2.2.1, thereby ensuring the operational stability of the stirring assembly 2 and improving operational safety.
[0029] Furthermore, the top of the tank 1 is provided with an inspection window. The mixing and storage tank also includes a cover plate 3 and a safety switch 4. The cover plate 3 is placed over the inspection window to seal the cavity 1.1, and the cover plate 3 is hinged to the edge of the inspection window. The safety switch 4 is located at the edge of the inspection window and is positioned between the power supply and the mixing drive component 2.1. The cover plate 3 is opened or closed to disconnect or connect the safety switch 4. The safety switch 4 enables the mixing shaft 2.2.1 to be forcibly stopped when the inspection window of the storage tank is opened, thus providing safety protection for the user and further improving operational safety.
[0030] Furthermore, the mixing and storage tank also includes a filter assembly 5, which is located at the slurry inlet 1.2. The slurry is injected into the cavity 1.1 through the slurry inlet 1.2 via the filter assembly 5 to filter out large particulate impurities in the slurry and ensure the quality of the slurry.
[0031] In this embodiment, the mixing and storage tank also includes multiple level gauges 6, which are arranged vertically at intervals on the tank body 1. The level gauges 6 are used to detect the slurry level in the tank body 1. The level gauges 6 can detect the slurry level in the tank body 1 in real time, so as to realize automatic grouting operation based on the information fed back by the level gauges 6.
[0032] In addition, the mixing and storage tank also includes a support frame 7 and a slurry discharge pipe 8. The support frame 7 has a support portion that matches the bottom wall of the cavity 1.1, and a hollow space is formed between the bottom wall of the cavity 1.1 and the support frame 7. The slurry discharge pipe 8 is located in the hollow space and connects the slurry discharge port to the grouting machine. The main frame can support the tank body 1 to form a hollow space at the bottom of the tank body 1, which facilitates the connection of the slurry discharge pipe 8 with the grouting machine at the slurry discharge port.
[0033] The bottom of the tank body 1 is also provided with a grout discharge port 9 that communicates with the cavity 1.1. After the grouting operation is completed or when the tank body 1 needs to be cleaned, the grout in the tank body 1 can be discharged through the grout discharge port 9.
[0034] The distance between the center of the bottom wall of cavity 1.1 and the top of tank 1 is h, and the radius of tank 1 is r. Then the included angle α ranges from 0 ≤ α ≤ arctan(r / h). This is to facilitate the installation of the stirring drive 2.1.
[0035] This embodiment also provides an automatic grouting device, including a controller 10, a grouting machine, a pulping machine, and a mixing and storage tank as described above. The controller 10 is electrically connected to the mixing drive 2.1 and the material level detector 6 in the grouting machine, the pulping machine, and the mixing and storage tank, respectively.
[0036] Since the automatic grouting device includes the mixing and storage tank as described above, it possesses all the beneficial effects of the mixing and storage tank, which will not be elaborated here.
[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
