DETAILED DESCRIPTION

[0013] like Figure 1-3As shown, a large-volume concrete cooling device of the present invention includes a water tank 7, the top of the water tank 7 is connected to the ice box 4, and an ice crushing chamber 9 is also provided in the water tank 7. Specifically, a horizontal plate and a vertical plate are fixed inside the water tank 7, the horizontal plate divides the water tank 7 into an upper driving chamber and a lower ice water chamber, and the vertical plate divides the ice water chamber into an ice crushing chamber 9 on one side and a circulation chamber on the other side.

[0014] like Figure 1 As shown, the ice box 4 is provided with an ice discharging mechanism for adding ice cubes into the ice crushing chamber 9, and the ice discharging mechanism can be an existing discharging component such as a star-shaped discharger. In this embodiment, the ice discharging mechanism includes a connecting channel 2 at the bottom of the ice box 4, and the bottom end of the connecting channel 2 is connected to the ice crushing chamber 9, so that the ice box 4 is connected to the ice crushing chamber 9 through the connecting channel 2, and a baffle 3 is slidably connected inside the connecting channel 2. A horizontal telescopic component 5 that drives the baffle 3 to slide is connected to the ice box 4 to open or close the connecting channel. The telescopic component 5 can be a linear drive component such as an electric cylinder or a cylinder. In some embodiments, the baffle 3 can also be replaced by a plate member that drives rotation to better close or open the channel for ice cubes to fall.

[0015] Specifically, the connecting passage 2 includes side panels extending downward on three adjacent sides of the ice box 4 and a vertical panel extending vertically downward. The vertical panel is fixed on two opposite side panels and forms a connecting passage 2 vertically downward with the three side panels, extending into the ice crushing chamber 9. The upper end of the vertical panel is also integrally connected with an inclined plate, which extends in an upward inclined direction toward the side away from the connecting passage 2 until it is fixed to the side of the ice box 4 away from the connecting passage 2. The baffle 3 horizontally penetrates the inclined plate and is driven to slide by an electric cylinder or a pneumatic cylinder to block or leave the top of the connecting passage 2, thereby completing the opening or closing of the connecting passage 2.

[0016] like Figure 1 As shown, a temperature sensor 25 is fixed inside the ice crushing chamber 9, and the temperature sensor 25 senses the temperature inside the ice crushing chamber 9 to control the operation of the ice discharging mechanism, that is, to control the operation of the electric cylinder; When the water flow inside the ice crushing chamber 9 reaches a certain temperature, the temperature sensor 25 controls the operation of the telescopic component 5, and the telescopic component 5 drives the baffle 3 to move, so that the connecting channel 2 is in an open state, and then the ice cubes fall into the ice crushing chamber 9, ensuring the water flow temperature inside the ice crushing chamber 9 to ensure the cooling effect on the concrete 13.

[0017] like Figure 1 As shown, a crushing mechanism for crushing ice cubes is also provided in the ice crushing chamber 9 to ensure the cooling effect of the cooling water; the crushing mechanism includes a plurality of rotating rods located in the ice crushing chamber 9, and a spirally arranged crushing blade 10 is fixed on each rotating rod.

[0018] In this embodiment, the rotating rod includes a first rotating rod 8 and a second rotating rod 11. A driving motor 1 is connected to the water tank 7. The output end of the driving motor 1 is coaxially connected and drives the first rotating rod 8 to rotate. In order to increase the crushing rate of ice cubes and reduce the use of motors, the upper ends of the first rotating rod 8 and the second rotating rod 11 are coaxially connected to the rotating gear 6. The two rotating gears 6 are meshed and connected with each other through a gear set (a driven gear) and driven to rotate together. The rotating gear 6 and the gear set are both located in the upper driving chamber.

[0019] When cooling the concrete 13, the motor is started, and the motor rotates through the first rotating rod 8. The first rotating rod 8 drives the second rotating rod 11 to rotate through the rotating gear 6, and then drives the crushing blade 10 to crush the ice, thereby ensuring the temperature of the cooling water and improving the crushing rate of the ice.

[0020] like Figure 1 As shown, the ice crushing chamber 9 is connected to a cooling pipe 12 for cooling the concrete 13. The cooling pipe 12 is distributed in the concrete 13 in a serpentine shape to improve the cooling effect. Both ends of the cooling pipe 12 are connected to the ice crushing chamber 9 through a filter screen, and a circulation mechanism is connected to the cooling pipe 12. The circulation mechanism is located in the circulation chamber and drives the coolant to circulate from the ice crushing chamber 9 to the cooling pipe 12. The circulation mechanism can be an existing water circulation drive device such as a water pump.

[0021] like Figure 2 As shown, in this embodiment, the circulation mechanism includes a piston cylinder 18, in which a circulation piston 17 is provided which moves up and down in the piston cylinder 18, a cooling water inlet pipe 14 is provided on one side of the piston cylinder 18, and a cooling water outlet pipe 15 is provided on the other side, and a one-way valve 20 is provided on both the cooling water inlet pipe 14 and the cooling water outlet pipe 15, and the direction of the one-way valve 20 is from the cooling water inlet pipe 14 to the cooling water outlet pipe 15.

[0022] When the concrete 13 is cooled, the circulating piston 17 is driven to reciprocate up and down by the driving component (linear module, cylinder, etc.), and the circulating piston 17 squeezes the water flow inside the piston cylinder 18. Under the action of the one-way valve 20, the water flows into the piston cylinder 18 through the water inlet pipe 14, and then is discharged from the water outlet pipe 15, thereby ensuring that the water flow can circulate inside the cooling pipe 12.

[0023] In order to improve the efficiency of water inlet and outlet, the cooling water inlet pipe 14 and the cooling water outlet pipe 15 are provided with two pairs of upper and lower pipes (both include an inlet / outlet main pipe and two upper and lower branch pipes 19 connected to the main pipe), and the piston moves between the upper and lower pairs of inlet and outlet pipes. Both pairs of cooling water inlet pipes 14 and cooling water outlet pipes 15 are provided with one-way valves 20 in the same direction.

[0024] like Figure 3As shown, the piston can be driven to slide up and down by existing devices such as a cylinder or a linear module. In this embodiment, in order to drive the up and down movement of the circulating piston 17, the circulating mechanism also includes a circular gear 22 located above the horizontal plate. One side of the circular gear 22 is rotatably connected to the water tank 7, and the other side is connected to an eccentrically arranged protrusion 24 (roller). The top of the piston is connected to the vertical connecting rod 16, and the top of the connecting rod 16 is connected to the horizontal limit frame 23. The limit frame 23 is provided with a horizontal slide groove that is compatible with the protrusion 24. When the circular gear 22 rotates, the protrusion 24 drives the limit frame 23 to move up and down.

[0025] In this embodiment, the rotating gear 6 on the first rotating rod 8 and the second rotating rod 11 and the circular gear 22 are driven to rotate together by helical gear meshing rotation, so as to reduce the use of motors. The circular gear 22 can also be directly driven to rotate by another motor. Specifically, a helical gear integrally connected to the rotating gear 6 is coaxially connected to the second rotating rod 11, and a gear shaft 21 is rotatably connected in the vertical plate. The gear at one end of the gear shaft 21 meshes with the helical gear, and the gear at the other end meshes with the circular gear 22, so as to drive the circular gear 22 to rotate through the driving motor 1.

[0026] The connecting rod 16 vertically penetrates the horizontal plate in the water tank 7 and the top plate of the piston cylinder 18 to guide the vertical sliding of the connecting rod 16; When the first rotating rod 8 rotates, the circular gear 22 is driven to rotate through the rotating gear 6 and the gear shaft 21. The circular gear 22 drives the protrusion 24 to make a circular motion. When the protrusion 24 makes a circular motion, the connecting rod 16 is driven to reciprocate up and down through the limit frame 23, thereby driving the piston to reciprocate, thereby saving energy.

[0027] Working principle of the present invention: When cooling the concrete 13, the circulation mechanism drives water to circulate in the ice crushing chamber 9 and the cooling pipe 12, thereby cooling the concrete 13. As time goes by, the temperature of the water will increase, and the water in the ice crushing chamber 9 will also decrease. When the water in the ice crushing chamber 9 reaches a certain temperature, the temperature sensor 25 detects the temperature of the water and controls the operation of the ice discharging mechanism, so that the ice cubes in the ice box 4 fall into the ice crushing chamber 9, and finally the ice cubes are crushed by the ice crushing mechanism. When the temperature in the ice crushing chamber 9 drops to a certain level, the ice discharging mechanism is controlled to stop operating, and the ice cubes stop falling at this time. The water is cooled by the ice cubes, and at the same time, a certain amount of water can be ensured in the ice crushing chamber 9, thereby ensuring the cooling effect on the concrete 13. The structure is simple and the construction cost is low.

[0028] The above describes a specific embodiment of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of the present invention, but these changes and modifications will fall within the scope of protection of the present invention.
