Description

Technical Field

[0001] This utility model relates to the field of slurry production, specifically a humidity control device for slurry production. Background Technology

[0002] Cement grout mainly comes in two types: injection grout and pressure grout. During the production of grout, cement and other components are made into dry powder, mixed, and then packaged. During the mixing process, humidity has a great influence on the quality of the grout. If the humidity is too high, the grout is prone to clumping after mixing, which is not conducive to subsequent construction. If the humidity is too low, dust is more likely to be generated during the mixing process, which will lead to deviations in the component ratio of the grout and affect the quality of the grout.

[0030] One embodiment of this utility model:

[0031] Reference Figures 1-7This utility model provides a humidity control device for slurry production, including a tank 10, an adjustable temperature stirring assembly rotatably disposed inside the tank 10, a cover 20 disposed at the upper end of the tank 10, and a receiving pipe 41 that rotates with the stirring assembly disposed on the lower side. In this embodiment, three heating rods 42 are fixed inside the receiving pipe 41, and the heating rods 42 can heat the airflow delivered into the stirring assembly.

[0032] Reference Figure 3 , Figure 4 The stirring assembly includes a stirring shaft 30, a connecting shaft 32, and a stirring rod 31. The stirring shaft 30, the connecting shaft 32, and the stirring rod 31 are all hollow tubular. The upper and lower ends of the stirring rod 31 are respectively fixed on the outer periphery of the connecting shaft 32 and the outer periphery of the stirring shaft 30. The stirring rod 31 is connected to the stirring shaft 30 and the connecting shaft 32. The connecting shaft 32 is connected to the receiving pipe 41.

[0033] Reference Figure 2 , Figure 3 A spline groove is provided on the outer periphery of the connecting shaft 32, and a spline is fixed on the inner side wall of the upper end of the receiving pipe 41. The connecting shaft 32 and the upper end of the receiving pipe 41 are splinedly connected. The upper end of the stirring shaft 30 is rotatably disposed inside the cover 20 and is driven to rotate by a drive system. The drive system includes a housing and a motor. The motor is fixed on the upper end face of the cover 20, and a drive gear is fixed on the output shaft of the motor. A bushing is rotatably connected inside the cover 20. The stirring shaft 30 can pass through the bushing and is splinedly engaged with the bushing (the spline groove at the upper end of the stirring shaft 30 is not shown). A driven gear is fixed on the upper end face of the bushing. The drive gear and the driven gear mesh (the tooth profiles of the drive gear and the driven gear are not shown). The upper end of the stirring shaft 30 passes through the driven gear and the housing. The motor, the drive gear, and the driven gear are all located inside the housing.

[0034] Reference Figure 4 The stirring rod 31 is arranged in a spiral around the axis of the stirring shaft 30.

[0035] Reference Figure 3 , Figure 7A sealing plug 43 is rotatably connected to the outer periphery of the receiving pipe 41. Three radially outward protruding rings are fixed on the outer periphery of the receiving pipe 41. An annular groove corresponding to the rings is opened in the sealing plug 43. The rings are rotatably connected in the annular groove, thereby increasing the connection strength between the receiving pipe 41 and the sealing plug 43. The diameter of the annular groove in the middle is larger than the diameter of the ring. Two arc-shaped conductive rings are fixed on the side wall of the annular groove in the middle. The two conductive rings are not in contact with each other. The two conductive rings are respectively connected to the positive and negative terminals of the power supply through wires. The wires are embedded in the sealing plug 43. Wires are connected to both ends of the three heating rods 42. The three heating rods 42 are connected in parallel. Two electric brushes are fixed in the outer periphery of the receiving pipe 41. The two electric brushes are respectively connected to the wires at both ends of the heating rods 42. The two electric brushes are in contact with the two conductive rings. A discharge port 40 communicating with the inside of the tank 10 is fixed on the bottom surface of the tank body 10. The sealing plug 43 is threadedly connected to the discharge port 40.

[0036] Reference Figure 1 The cover 20 is detachably connected to the upper end of the tank 10. A filter screen 21 is fixed inside the cover 20. The filter screen 21 can be fixed to the cover 20 by bolts.

[0037] Reference Figure 2 , Figure 3 A humidity sensor for detecting the humidity inside the tank 10 is fixed on the lower end face of the cover 20. The humidity sensor is electrically connected to the heating rod 42 through the central processing unit. The humidity sensor detects the humidity inside the tank 10 and transmits the detected humidity information to the central processing unit. By comparing it with the preset threshold in the central processing unit, when the humidity is higher than the threshold, the central processing unit controls the heating rod 42 and the air pump to start, thereby introducing heated air into the stirring assembly to stir the slurry and accelerate the evaporation of water from the slurry.

[0038] During the slurry production and mixing process, the connecting shaft 32 is first inserted into the upper end of the receiving pipe 41, and then the slurry is poured into the tank 10. The upper end of the stirring shaft 30 is aligned with the bushing inside the cover 20, and the stirring shaft 30 is inserted into the bushing so that the cover 20 covers the upper end of the tank 10. The motor is then started, which causes the stirring shaft 30 to rotate, thereby driving the stirring rod 31 to rotate, thus stirring the slurry in the tank 10.

[0039] During this process, the humidity sensor monitors the humidity of the tank 10 in real time during slurry mixing and transmits the detected data to the central processing unit. When the detected humidity exceeds a preset threshold in the central processing unit, the central processing unit controls the heating rod 42 to be energized to generate heat, and simultaneously starts the air pump to supply air into the receiving pipe 41. The air is heated by the heating rod 42 and enters the connecting shaft 32, flows through the stirring rod 31, and is discharged through the stirring shaft 30, thereby increasing the temperature of the stirring rod 31 and heating the slurry powder. This process allows the moisture in the slurry to evaporate further, thereby reducing the slurry's humidity. At the same time, the evaporated moisture in the slurry is discharged through the filter screen 21, while the dust generated during the mixing of the slurry is trapped inside the tank 10 by the filter screen 21. If the dust and moisture mix and adhere to the holes of the filter screen 21 for a long time, the clogged filter screen 21 can be removed and replaced with a new filter screen 21 to ensure its filtration effect, reduce the humidity of the slurry, and reduce the amount of slurry dust discharged outside the tank 10. This ensures the accurate proportion of each component in the slurry, thereby increasing the production quality of the slurry.

[0040] After the slurry is thoroughly mixed, open the cover 20, pull the stirring shaft 30 upward to separate the lower end of the connecting shaft 32 from the receiving pipe 41, and then rotate the sealing plug 43 to remove the sealing plug 43 from the discharge port 40. At this time, the slurry in the tank 10 can be discharged and collected through the discharge port 40.

[0041] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
