Description

Technical Field

[0001] This utility model relates to the field of circulating fan technology, specifically a fixed circulating fan for low-temperature grain depots. Background Technology

[0002] Currently, circulating fans are a commonly used ventilation device in low-temperature grain depots. In low-temperature grain depots, all stored grain is concentrated within the depot itself. To ensure air circulation within the storage area, circulating fans need to be installed to achieve this purpose.

[0003] Currently, the circulating fans generate significant noise during operation, which disturbs the surrounding environment of the grain depot. Furthermore, the vibrations generated by the circulating fans during prolonged operation can loosen the fixing screws, potentially causing the circulating fans to become loose. Utility Model Content

[0022] Please see Figure 1-3 This utility model provides a technical solution: a fixed circulating fan for low-temperature grain depots, comprising:

[0023] Fan frame 1;

[0024] A shock-absorbing and fixing structure is installed on the fan frame 1;

[0025] The vibration damping and fixing structure includes a rubber ring 2, two clamping frames 3, two sets of reinforcing frames 4, and a mounting plate 5. The inner wall of the rubber ring 2 is fitted onto the fan frame 1. The bottoms of the two clamping frames 3 are hinged together, and the tops of the two clamping frames 3 are fixed together by multiple main bolts. The rubber ring 2 is fitted between the two clamping frames 3. The two sets of reinforcing frames 4 are respectively fixedly embedded in the two clamping frames 3. Multiple threaded rods 6 are fixedly provided on the top of the outer wall of each of the two clamping frames 3. The bottom of the mounting plate 5 is slidably fitted onto the multiple threaded rods 6 and fixed with nuts.

[0026] The fan structure is located inside the fan frame 1.

[0027] In this implementation scheme: the fan frame 1 can protect the rotation of the blades. The two clamping frames 3 are hinged at the bottom and wrapped around the fan frame 1, with a rubber ring 2 placed between them to absorb vibration. The reinforcing frame 4 can reinforce the clamping frames 3, making the clamping frames 3 stronger as a whole and preventing the clamping frames 3 from shaking. The tops of the two clamping frames 3 are also fixed together with bolts. The multiple threaded rods 6 at the top can make the mounting plate 5 be placed accordingly and fixed with nuts.

[0028] Specifically, the fan structure includes four fixing parts 7, four clamping plates 8, a motor body 9, and a fan blade body 10. The ends of the four clamping plates 8 that are far apart from each other are respectively fixed to the fan frame 1 by the four fixing parts 7.

[0029] In this embodiment, four clamping plates 8 can be fixed inside the fan frame 1 by four fasteners 7.

[0030] Specifically, the four clamping plates 8 are fixed on the motor body 9 at their closest points, and the four clamping plates 8 are arranged at equal intervals along the circumference.

[0031] In this embodiment, the motor body 9 can be positioned in the central area and fixed by the four clamping plates 8.

[0032] Specifically, the outer wall of the fan blade body 10 is fixed on the output end of the motor body 9.

[0033] In this embodiment, the output end of the motor body 9 drives the fan blade body 10 to rotate when the motor body 9 is powered on.

[0034] Specifically, machine mesh covers 11 are fixedly installed on both sides of the outer wall of the fan frame 1.

[0035] In this embodiment, the machine mesh cover 11 provides protection.

[0037] In this embodiment, the installation and fixing operation is carried out through the two sets of mounting holes 12 on the mounting plate 5.

[0038] During use, the two sets of mounting holes 12 on the mounting plate 5 are used for installation and fixing. The fan frame 1 can protect the rotation of the blades. The two clamping frames 3 are wrapped around the fan frame 1 by the hinge at the bottom, and rubber rings 2 are placed between them to absorb vibration. The reinforcing frame 4 can reinforce the clamping frames 3, making the clamping frames 3 stronger as a whole and preventing the clamping frames 3 from shaking. The tops of the two clamping frames 3 are also fixed together with bolts. The multiple threaded rods 6 at the top can be placed correspondingly on the mounting plate 5 and fixed with nuts. The four fasteners 7 can fix the four clamping plates 8 inside the fan frame 1. The four clamping plates 8 can keep the motor body 9 in the central area and fix the motor body 9. When the motor body 9 is powered on, the output end drives the fan blade body 10 to rotate. The whole is wrapped around the fan frame 1 with rubber and fixed by the clamping frames 3, so that the vibration generated by the fan is absorbed by the rubber, reducing vibration to suppress noise generation and making the installation more secure.
