Description

Technical Field

[0001] The utility model relates to the technical field of aeration devices and sewage treatment, in particular to a foldable aeration device and sewage treatment equipment comprising the aeration device. Background Art

[0002] Rural domestic sewage treatment is of great significance to improving the rural living environment. In recent years, a large number of rural biochemical sewage treatment facilities have been built. However, due to the increasing construction years of some rural domestic sewage treatment facilities, the aeration system of the aerobic pool has gradually experienced problems such as blockage, damage, and aeration head detachment. The original aeration system is fixedly installed inside the integrated treatment facility, which is difficult to repair and replace.

[0003] The application number is 202320985458.1, and the name is a liftable aeration device that is easy to maintain and replace. Each aeration pipe is arranged at the intersection of two scissor rods. The scissor rods are controlled to extend by a pushing mechanism so that the aeration pipes are laid flat on the bottom of the treatment pool for uniform aeration. At the same time, the scissor rods can be retracted, and the assembly frame can be pulled up by the lifting mechanism to lift the aeration pipe above the treatment pool, which is convenient for operators to replace and maintain and saves manpower and material resources.

[0004] Although the patent discloses a foldable aeration device, it is aimed at an open treatment pool. Since the device is rectangular in shape and large in size, it is difficult to lower it into the sewage treatment facility through the inspection well of the sewage treatment facility. In addition, it requires electrical control, which brings great costs to the maintenance and replacement of rural domestic sewage treatment facilities, making it difficult to promote and apply.

The fifth rotation axis 95 is located between the third rotation axis 93 and the fourth rotation axis 94, and the second rotation axis 92 is located between the sixth rotation axis 96 and the seventh rotation axis 97. The arrangement of the rotating shaft 9 and the connecting rod 10 enables the telescopic mechanism to be folded and unfolded, thereby driving the folding and extension of the gas path mechanism. The eighth rotating shaft 98 and the ninth rotating shaft 99 are arranged corresponding to the position of the hose 5 to facilitate the folding or extension of the gas path mechanism.

[0037] In this embodiment, a connecting mechanism 11 is provided between the telescopic mechanism and the gas path mechanism, and the connecting mechanism 11 is used to connect the aeration branch pipe 6 and the connecting rod 10 of the telescopic mechanism. The center rod 1 and the slider 2 are provided with a fixing mechanism, and the fixing mechanism is used to fix the position of the slider 2 on the center rod 1. Preferably, the fixing mechanism includes a threaded hole penetrating the wall thickness of the slider 2 and a fastener provided in the threaded hole, and the fastener has an external thread. The slider 2 is fixed to the center rod 1 by the cooperation of the fastener and the threaded hole, thereby fixing the expansion degree of the aeration device, and facilitating the storage and control of the aeration area.

[0038] The aeration device has a folded state and an unfolded state; the slider 2 moves downward along the central rod 1, the telescopic mechanism and the air path mechanism extend outward in a direction away from the central rod 1, and the aeration device is in an unfolded state; the slider 2 moves upward along the central rod 1, the telescopic mechanism and the air path mechanism shrink inward in a direction close to the central rod 1, and the aeration device is in a folded state.

[0039] like Figure 5As shown, this embodiment also provides a sewage treatment device, including a sewage treatment device 12 and the above aeration device, and the sewage treatment device 12 has an inspection well 13. The following briefly describes the process of lowering the above aeration device into the sewage treatment device 12:

[0040] First, the aeration device is placed in a folded state. At this time, the distance between the first rotating axis 91 of the first connecting rod 101 and the third rotating axis 93 of the second connecting rod 102 is larger or maximum, and the distance between the connecting rods 10 is smaller or minimum. Since the aeration branch pipe 6 in the air path mechanism is connected to the connecting rod 10 through the connecting mechanism 11, the aeration branch pipe 6 is folded through the hose 5 under the drive of the connecting rod 10, and the distance between the aeration branch pipes 6 is also smaller or minimum.

[0041] After folding, the aeration device is extended into the sewage treatment device 12 through the inspection well 13, and when it is lowered to a suitable position, the slider 2 is moved downward along the central rod 1. During operation, the slider 2 is pushed downward to reduce the distance between the first rotation axis 91 of the first connecting rod 101 and the third rotation axis 93 of the second connecting rod 102, and the telescopic mechanism is extended away from the central rod 1 through the cooperation of the connecting rod 10 and the rotation axis 9, thereby driving the gas path mechanism to extend outward; at the same time, the central rod 1 can be lifted upward to move the slider 2 downward as much as possible, so that the degree of expansion of the gas path mechanism in the expanded state is maximized.

[0042] After the expansion is to a suitable extent, the position of the slider 2 on the central rod 1 is fixed by a fixing mechanism, thereby fixing the expansion extent of the gas path mechanism. The central rod 1 is moved downward to a suitable position, and then the aeration main pipe 4 is connected to the fan 14 to achieve aeration.

[0043] In other embodiments, the position of the slider 2 on the central rod 1 can be fixed by a fixing mechanism, thereby fixing the expansion degree of the air path mechanism and adjusting the concentration degree of the aeration area.

[0044] The foldable aeration device provided by the utility model is placed inside the aerobic pool inspection well of the rural domestic sewage integrated treatment facility and then unfolded to replace the original aeration system that has failed. The degree of concentration of the aeration area can be adjusted by the degree of unfolding of the aeration system. In the foldable aeration device of the utility model, the slider 2 is sleeved on the central rod 1, which can slide and be fixed at various places of the central rod 1. When the slider 2 is far away from the bottom of the central rod 1, the aeration device is folded and can be placed inside the rural domestic sewage integrated treatment device 12 through the aerobic pool inspection well 13. After being placed, the distance between the slider 2 and the bottom of the central rod 1 is reduced, so that the connecting rod 10 rotates at the rotating shaft 9 to unfold the entire aeration device. After that, the aeration main pipe 4 is inflated by the fan 14, and the aeration main pipe 4 is connected to the air path distributor 3, and after passing through the elbow 7 connected to the air path distributor 3, it is connected to the aeration branch pipe 6 through the hose 5. The aeration branch pipe is fixed on the connecting rod 10 through the fixing mechanism 11, and the folded part is connected with the hose 5, and the end of the aeration branch pipe 6 is connected to the aeration head 8. The aeration device of the utility model is provided with a multi-link structure and a slider moving along a center rod, and the movement of the slider drives the multi-link structure to fold and unfold, thereby driving the air path mechanism to fold and stretch, thereby achieving volume control of the aeration device, facilitating the aeration device to be lowered through the inspection well of the sewage treatment device and then unfolded inside the device, and the concentration of the aeration area can be adjusted.

[0045] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
