[0021] In this embodiment, automatic opening and closing is achieved through the control of infrared sensors, which effectively reduces the pressure of manual operation, improves work efficiency, reduces labor costs, and shortens the waiting time of transport vehicles at the entrance and exit of the silo, avoiding the problem of low silo environment temperature caused by long-term opening and closing of the thermal insulation door curtain. In addition, during winter construction, the automatic induction thermal insulation door curtain can maintain a stable temperature in the silo environment, effectively meet construction needs, ensure the quality of concrete, and effectively guarantee the construction progress of the project.

[0022] Specifically, in this embodiment, two 5m long steel columns are selected to stand on both sides of the door frame as the support columns 1 of the entire thermal insulation curtain 6, and a 4m long steel plate is selected with its left and right ends 4.5m away from both sides of the door frame and welded to the support as a crossbeam. Then a 3.8m long aluminum alloy plate is selected as the track 3, and an inverted trapezoidal groove with a horizontal upper bottom of 6cm and a lower bottom of 3cm is chiseled out under the aluminum alloy plate. Then, a 3.5m long and 2cm wide hole 301 is chiseled out in the center of the front and rear positions of the aluminum alloy plate, and the upper ends of 8 10cm long steel plates are welded to the lower side of the top beam 2 at a spacing of 40cm in sequence, and the lower ends are welded to the upper side of the track 3.

[0023] Furthermore, the infrared sensor 5 is arranged on the front and rear surfaces of the top beam 2, and a multi-layer insulating material is selected to make a heat preservation curtain 6, and holes are punched at the upper end thereof. Six rings are used to hang it on the hole 301 of the track 3, and then a brick is fixed at the lower end of the heat preservation curtain 6. A steel block is selected and cut into an inverted trapezoidal block with an upper bottom of 5.8 cm and a lower bottom of 2.8 cm, and inserted into the groove from the left side of the track 3; a motor with a power of 170W is used to electrically connect the infrared sensor with the drive motor 10 and the winding device of the traction structure to realize automatic control. An infrared detector is arranged inside the infrared sensor 5, and the infrared detector detects infrared radiation by using the physical effect presented by the interaction between infrared radiation and the vehicles entering and exiting, so as to determine whether there are vehicles entering and exiting. In addition, the infrared sensor 5 has an adjustable sensing distance and angle, which can adapt to vehicles of different sizes and shapes.

[0024] In an exemplary embodiment, the traction structure includes a first reel 11, a second reel 12 and a traction rope 9, wherein the first reel 11 is arranged above the right end of the track 3, and the second reel 12 is arranged below the right end of the track 3, the first reel 11 and the second reel 12 are designed with an automatic locking mechanism, one end of the traction rope 9 is connected to the first reel 11, and the other end is connected to the second reel 12, and the upper and lower parts of the traction rope 9 on the track 3 are respectively kept level with the corresponding parts.

[0025] Specifically, a steel wire rope with a diameter of 10 mm to 14 mm is selected to make the traction rope 9 in order to improve durability and reduce tensile deformation. The traction rope 9 is first led out from the first reel 11, horizontally moved to the left along the upper side of the track 3, bypassed the fixed pulley 4, and then passed through the slider 8 to the right. Then, it returns to the second reel 12 horizontally along the lower side of the track 3, and the contact point between the steel wire rope and the slider 8 is welded.

[0026] Furthermore, when the infrared sensor 5 facing outward of the top beam 2 recognizes that a vehicle is entering, the drive motor 10 starts to rotate forward, the first reel 11 releases the traction rope 9 outward, and the second reel 12 reels in the traction rope 9, thereby pulling the slider 8 to slide to the right along the track 3, pushing the suspension ring 7 to move horizontally to the right, and the thermal insulation curtain 6 opens to the right. After opening, the first reel 11 and the second reel 12 are automatically locked, and the vehicle passes. When the infrared sensor 5 facing inward of the top beam 2 recognizes that a vehicle is leaving, the drive motor 10 starts to rotate backward. Due to the automatic locking mechanism of the first reel 11 and the second reel 12, at this time, the second reel 12 releases the traction rope 9 outward, and the first reel 11 reels in the traction rope 9, thereby pulling the slider 8 to slide to the left along the track 3, dragging the suspension ring 7 to move horizontally to the left, and the thermal insulation curtain 6 closes to the left.

[0027] In an exemplary embodiment, the automatic induction thermal insulation curtain 6 of the mixing station silo further includes a fixed pulley 4 fixed to the left end of the track 3 , and the traction rope 9 passes around the fixed pulley 4 .

[0029] Specifically, when the slider 8 reaches the leftmost end of the track 3, the first reel 11 and the second reel 12 are automatically locked by the automatic locking structure, and the slider 8 stops sliding.

[0030] In the exemplary embodiment, the two support columns 1 are fixed to the wall by bolts to prevent the thermal insulation curtain 6 from tilting.

[0031] In the exemplary embodiment, a lighting device is provided on the top beam 2 .

[0032] In this embodiment, by connecting a lighting device to a power source on the top beam 2, lighting is provided when light is insufficient, thereby improving the performance of the infrared sensor 5.

[0033] In an exemplary embodiment, a buffer pad is provided in the inverted trapezoidal groove as a buffer structure for reducing noise when the slider 8 moves.

[0034] In an exemplary embodiment, a rotating bracket is disposed on the base of the infrared sensor 5 so that the infrared sensor 5 has an adjustable sensing distance and angle, thereby allowing the infrared sensor 5 to adapt to vehicles of different sizes and shapes.

[0035] In an exemplary embodiment, the thermal insulation curtain 6 is made of multiple layers of insulating material, and a weight block is provided at the lower end of the thermal insulation curtain 6 .

[0036] Specifically, the thermal insulation curtain 6 is made of multiple layers of insulating materials to improve the thermal insulation effect. A weight block is provided at the lower end of the thermal insulation curtain 6 to maintain the stability of the thermal insulation curtain 6 in the unfolded state.

[0037] In the exemplary embodiment, a manual emergency operation device is provided on the driving motor 10 .

[0038] Specifically, the manual emergency operation device is a manual button. When the drive motor 10 is powered off or in other necessary circumstances, the manual button can be pressed to shut down the drive motor 10 to prevent the drive motor 10 from being damaged due to rotor inertia.
