Description

TECHNICAL FIELD

[0001] The present application relates to the field of concrete construction, in particular to a concrete cooling device. BACKGROUND

[0002] The concrete cooling device is a device for reducing the temperature of concrete. Since the hydration reaction of cement generates a large amount of heat, the temperature of concrete rises. If the temperature is not reduced in time, the strength and durability of the concrete will be affected. Therefore, the concrete cooling device is needed to reduce the temperature of the concrete. The use of the concrete cooling device can effectively control the temperature of the concrete, improve the strength and durability of the concrete, and thus ensure the engineering quality and safety. At the same time, the concrete cooling device can also improve the construction efficiency, shorten the construction period, and reduce the engineering cost.

[0003] The concrete cooling device usually adopts water cooling or air cooling. The heat in the concrete is absorbed by circulating water or air, and then taken away, so as to achieve the purpose of temperature reduction. The specific implementation modes include embedding cooling water pipes in concrete, spraying water mist, and using fans. The air cooling mode is more convenient because it does not need to control the water content of the concrete. However, the air cooling device needs to be regularly maintained and cleaned. If the maintenance is not timely or not in place, the performance of the device may be reduced.

[0004] At present, the concrete air cooling device in the prior art is usually a wall-mounted fan. The wall-mounted fan is attached to the outside of the mixing building by a bolt through an integrated extension. For the connection tightness and firmness of the air cooling device, the bolt pre-tightening can prevent air leakage and other problems. However, the wall-mounted fan is large in size. When it is maintained outside the mixing building, the wall-mounted fan loses support after the bolt is removed, so that it needs to be transferred by using hoisting equipment, which is not convenient. To solve the above problems, a concrete cooling device is proposed. CONTENT OF THE UTILITY MODEL

[0005] In view of the deficiencies of the prior art, the present application provides a concrete cooling device which has the advantages of convenient adjustment and separation, and provides maintenance convenience.

[0006] In summary, the present application provides the following technical solution: a concrete cooling device, comprising a mixing building bin for mixing concrete, an aggregate bin built in the mixing building bin, an air cooling pipe connected to the outside of the mixing building bin, a blower connected to the air cooling pipe, and an air cooling device attached to the outside of the mixing building bin, the air cooling device comprising a wall-mounted fan, a support beam fixedly installed below the wall-mounted fan, a support mechanism arranged on the two side walls of the mixing building bin for supporting the support beam, and a communication mechanism arranged on one end of the air cooling pipe facing the wall-mounted fan.

[0007] By adopting the above technical solution, the wall-mounted fan can be moved horizontally relative to the mixing plant silos after separation, so that the wall-mounted fan can be supported after separation without the need for external assistance, which facilitates further maintenance.

[0008] Furthermore, the support mechanism includes a guide rail fixedly installed on the outer wall of the mixing plant silo, a slide plate slidably connected to the guide rail, and a locking rod component for limiting the position of the slide plate. The locking rod component includes two support rods rotatably installed on both sides of the slide plate, a slider slidably attached to the inner wall of the guide rail, and a pre-tightening member connected between the two support rods.

[0009] By adopting the above technical solution, the movement of the skateboard relative to the guide rail can be effectively supported and restricted.

[0010] Furthermore, the wall-mounted fan is internally fixedly equipped with heat dissipation fins, and externally fixedly equipped with heat exchange tubes, which are externally connected to a refrigeration plant's cold nitrogen pipe.

[0011] By adopting the above technical solution, the air-cooled equipment for concrete can obtain a cold source and improve the cooling effect.

[0012] Furthermore, the slide plate has two support rods on one side, the two support rods are symmetrically arranged on the slide plate, and the slider and the support rods are rotatably connected at the end away from the slide plate.

[0013] By adopting the above technical solution, the opening and closing angle of the support rod can be changed when the skateboard slides relative to the guide rail.

[0014] Furthermore, the pretensioning component includes a fixed sleeve fixedly connected to the support rod, an adjusting rod rotatably connected between the two fixed sleeves, and a locking sleeve. The end of the adjusting rod facing between the two fixed sleeves has a rectangular cross-section, and the two adjusting rods are slidably connected to the locking sleeve together.

[0015] By adopting the above technical solution, the movement of the two adjusting rods is guided and always parallel to the slide plate.

[0016] Furthermore, the locking sleeve slides against the guide rail, and a locking pin is pre-tightened on the locking sleeve's thread.

[0017] By adopting the above technical solution, the sliding of the adjusting rod relative to the locking sleeve can be restricted by extending the locking pin into the locking sleeve.

[0018] Furthermore, the communication mechanism includes a connecting pipe connecting to the outside of the wall-mounted fan, an outer protective component disposed between the connecting pipe and the air-cooling pipe, and a sealing sleeve fixedly installed on the end of the connecting pipe facing the air-cooling pipe.

[0019] By adopting the above technical solution, the tightness of the connection between the connecting pipe and the air-cooling pipe can be improved.

[0020] Furthermore, the outer protective component includes a connecting plate fixedly installed outside the connecting pipe, a corrugated pipe fixedly connected to the connecting plate, and a fixing plate fixed outside the air-cooling pipe.

[0021] By adopting the above technical solution, external protection can be achieved at the joint position of the air-cooled pipe and the connecting pipe.

[0022] This concrete cooling device features a wall-mounted fan connected to a sliding plate via a support beam at one end, which is slidably connected to a guide rail. This allows the wall-mounted fan to be supported during disassembly, eliminating the need for overall hoisting and disassembly. Furthermore, the support rod restricts the movement of the sliding plate relative to the guide rail, improving the stability of the wall-mounted fan after installation and adjustment, thus enhancing the safety of maintenance and cleaning. Additionally, the corrugated pipe provides external protection at the connection point, extending the service life of the wall-mounted fan and the cooling device, thereby improving the device's practicality.

[0030] Please see Figure 1 A concrete cooling device in this embodiment includes a mixing plant silo 1 for mixing concrete, an aggregate silo 2 built into the mixing plant silo 1, an air-cooling pipe 3 connected to the outside of the mixing plant silo 1, a blower 12 connected to the air-cooling pipe 3, and an air-cooling device attached to the wall and installed outside the mixing plant silo 1.

[0031] Furthermore, the air-cooling device includes a wall-mounted fan 7, a support beam 6 fixedly installed below the wall-mounted fan 7, a support mechanism provided on both sides of the mixing plant silo 1 to support the support beam 6, and a connecting mechanism provided on one end of the wall-mounted fan 7 facing the air-cooling pipe 3.

[0032] It should be noted that the wall-mounted fan 7 has heat dissipation fins 8 fixedly installed inside to increase the heat exchange contact surface, and heat exchange tubes 9 fixedly installed outside the wall-mounted fan 7 for contact heat exchange. The heat exchange tubes 9 are connected to the external cold nitrogen pipe 10 of the refrigeration plant. The cold nitrogen pipe 10 of the refrigeration plant is directly supplied with liquid nitrogen by the refrigeration plant to provide a cold source for participating in heat exchange.

[0033] Please see Figures 1-2 In this embodiment, the support mechanism includes a support guide rail 4 fixedly installed on the outer wall of the mixing plant silo 1, a sliding plate 5 slidably connected to the guide rail 4, and a locking rod component for limiting the position of the sliding plate 5. The sliding plate 5 is detachably connected to the support beam 6. The support guide rail 4 is U-shaped and welded to the outside of the mixing plant silo 1 from the side, and both ends are closed by welding plates to prevent the sliding plate 5 from sliding horizontally out of the guide rail 4.

[0034] Please see Figures 2-3 It should be noted that the locking rod component includes two support rods 13 rotatably mounted on both sides of the slide plate 5, a slider 14 slidably attached to the inner wall of the guide rail 4, and a pre-tightening member connecting the two support rods 13.

[0035] The slide plate 5 has two support rods 13 on one side. The two support rods 13 are symmetrically arranged on the slide plate 5, and the slider 14 and the support rods 13 are rotatably connected to the end of the slide plate 5 away from the slide plate 5, so that the opening and closing angle of the support rods 13 can be changed when the slide plate 5 slides relative to the guide rail 4.

[0036] Please see Figures 2-3 In this embodiment, the pretensioning component includes a fixed sleeve 15 fixedly connected to the support rod 13, an adjusting rod 16 rotatably connected between the two fixed sleeves 15, and a locking sleeve 17. The end of the adjusting rod 16 facing between the two fixed sleeves 15 has a rectangular cross section, and the two adjusting rods 16 are slidably connected to the locking sleeve 17 together.

[0037] During the rotation of the support rod 13, the two adjusting rods 16 rotate relative to the fixed sleeve 15, and the adjusting rods 16 slide relative to the locking sleeve 17 to change the length of their insertion within the fixed sleeve 15.

[0038] Understandably, the locking sleeve 17 slides against the guide rail 4 to maintain the position of the locking sleeve 17. The locking sleeve 17 has a pre-tightened locking pin 18 on its thread. The locking pin 18 can extend into the locking sleeve 17 to restrict the sliding of the adjusting rod 16 relative to the locking sleeve 17, thereby completing the fixation of the position of the support rod 13.

[0039] Please see Figures 4-5 In this embodiment, the connecting mechanism includes a connecting pipe 11 connected to the outside of the wall-mounted fan 7 and an outer protective component disposed between the connecting pipe 11 and the air-cooling pipe 3. A sealing sleeve 19 is fixedly installed on the end of the connecting pipe 11 facing the air-cooling pipe 3. The tightness of the connection can be improved by the mutual sleeve between the sealing sleeve 19 and the air-cooling pipe 3.

[0040] It should be noted that the external protective components include a connecting plate 20 fixedly installed on the outside of the connecting pipe 11, a corrugated pipe 21 fixedly connected to the connecting plate 20, and a fixing plate 22 fixed on the outside of the air-cooling pipe 3. The end of the corrugated pipe 21 away from the connecting plate 20 is fixedly connected to the fixing plate 22 by bolts, thereby achieving external protection for the mating position of the air-cooling pipe 3 and the connecting pipe 11. At the same time, when disassembling, the corrugated pipe can be pulled apart to disconnect the connection.

[0041] The working principle of the above embodiments is as follows:

[0042] When maintenance and cleaning of the cooling device are required, the connecting plate 20 for external protection and the end of the bellows 21 are connected in contact. After unscrewing the fixing bolts, the bellows 21 is pulled open, exposing the sealing sleeve 19 and the air-cooling pipe 3. By further releasing the locking pin 18 connected to the threaded lock sleeve 17, the adjusting rod 16 can slide relative to the lock sleeve 17 for adjustment. At this time, the support rod 13 can slide relative to the sliding plate 5, thereby adjusting the position of the sliding plate 5 and the support beam 6. After the external connection of the wall-mounted fan 7 is released, the wall-mounted fan 7 can be moved relative to the mixing plant silo 1, thereby improving the convenience of maintenance and eliminating the need for additional hoisting equipment to move the wall-mounted fan 7.
