Description

Technical Field

[0001] The utility model discloses a rainproof and breathable device for the mud line silo level gauge, belonging to the auxiliary device of the level gauge. Background Art

[0002] Sludge is generated during the process of treating raw water by tap water, and these sludges mainly come from the coagulation sedimentation and filtration processes of water.

[0003] During the process of treating raw water, these sludges will accumulate in the raw water treatment silo, and an ultrasonic level gauge needs to be set to detect the mud line in the silo. In the prior art, the level gauge is mostly directly installed in the silo, and is easily damaged and the measurement is inaccurate due to being affected by harsh environments such as water vapor and humidity for a long time.

[0004] In order to protect the level gauge and improve its working environment, there are also level gauges with rainproof devices in the prior art. For example, the "detachable rainproof silo top level gauge for a thermal power plant ash silo" disclosed in Chinese Patent No. ZL201420148501.X (the authorization announcement date is August 6, 2014) includes a level gauge body, a fixed flange, an installation reverse flange and a rainproof cover. The level gauge body is installed on the fixed flange, and the fixed flange and the rainproof cover are fixedly connected to the installation reverse flange again. This patent application case can facilitate the calibration or maintenance of the level gauge by setting a detachable rainproof cover, greatly improve the working environment of the level gauge, reduce the rust of the head of the level gauge, and extend the service life of the level gauge. However, this kind of rainproof device is not applicable to the level gauge in the sludge treatment silo. The main reason is that the above rainproof cover adopts a closed structure, while the detection environment of the mud line silo level gauge is a humid environment itself. Although the closed rainproof cover can prevent external rain, it cannot effectively discharge the internal moisture, and the adverse factors such as internal water vapor and humidity will directly affect the normal operation of the level gauge, resulting in a reduction in the stability and service life of the mud line silo level gauge.

[0005] In view of the above problems, it is necessary to design a special rainproof and breathable device for the mud line silo level gauge. Summary of the Invention

Detailed Embodiments

[0038] To further understand the content of the present utility model, the present utility model will be described in detail in combination with the drawings and embodiments.

[0039] [Embodiment 1]

[0040] Combined with Figure 1As shown in the figure, a rainproof and breathable device for the mud line silo level gauge in this embodiment is installed on the top of the mud line silo and is used for the support, rainproof and ventilation of the level gauge. It includes a level gauge outer sleeve 1, a level gauge inner support 2, a rainproof cap 3 and a rainproof cap support 4. Among them, the level gauge outer sleeve 1 is installed on the top of the mud line silo, and the level gauge outer sleeve 1 is vertically penetrated as a channel for the level gauge to extend out of the mud line silo. The level gauge inner support 2 is installed on the upper part of the level gauge outer sleeve 1 for installing the level gauge, and a bottom ventilation window 5 is formed between the level gauge inner support 2 and the level gauge outer sleeve 1, which can make the air inside the level gauge outer sleeve 1 form air convection and prevent the accumulation of internal moisture. The rainproof cap 3 is fixedly installed above the level gauge outer sleeve 1 through the rainproof cap support 4, and a side ventilation window 6 is formed below the rainproof cap 3. The rainproof cap 3 can prevent the influence of rain on the level gauge and use the side ventilation window 6 to realize air flow, ensuring that the level gauge works in a dry environment and effectively protecting the level gauge from water vapor erosion. This rainproof and breathable device for the mud line silo level gauge avoids the direct influence of adverse factors such as internal water vapor and humidity on the level gauge by extending part of the structure of the level gauge outside the sludge silo. The design of the ventilation window can ensure that the working environment of the level gauge is dry, significantly improving the service life and stability of the level gauge and reducing the damage and malfunction caused by environmental factors.

[0041] As Figure 2 and Figure 3 shown in the figure, in this embodiment, the level gauge inner support 2 includes a central ring 2-1 and a plurality of connecting legs 2-2 distributed on the outer periphery of the central ring 2-1. The ends of the connecting legs 2-2 are fixedly connected to the pipe wall of the level gauge outer sleeve 1. A central mounting hole 2-3 for the level gauge to extend out is provided in the middle of the central ring 2-1, and the bottom ventilation window 5 is located on the outer periphery of the central ring 2-1. With this design of the level gauge inner support 2, the bottom ventilation window 5 can be formed by using the space between the connecting legs 2-2, and the structure is simple and easy to manufacture. Further, the ends of the connecting legs 2-2 are welded to the pipe wall of the level gauge outer sleeve 1, making the level gauge inner support 2 and the level gauge outer sleeve 1 form an integral module, which is convenient for subsequent installation. Bolt holes 2-4 are also provided on the connecting legs 2-2, and the lower end of the rainproof cap support 4 is bolted to the corresponding connecting legs 2-2 to fix the rainproof cap support 4 by using the connecting legs 2-2, which is convenient for assembly and the overall structure is stable and reliable. In addition, in this embodiment, the connecting legs 2-2, the rainproof cap support 4 and the flange of the level gauge are simultaneously fixedly connected together by bolts passing through the bolt holes 2-4. That is to say, the connecting legs 2-2, the rainproof cap support 4 and the flange of the level gauge can be fixed by a set of screws. The design of the level gauge inner support 2 allows the simultaneous fixation of the rainproof cap support 4 and the level gauge, improving the installation efficiency and stability.

[0042] As Figure 4As shown in the figure, in this embodiment, the rain-proof cap support 4 is in an "L" shape, including a vertical section 4-1 and a horizontal section 4-2 connected together. The horizontal section 4-2 is located at the lower end of the vertical section 4-1, and a connection hole 4-3 corresponding to the first bolt hole 2-4 on the corresponding connection leg 2-2 is also provided on the horizontal section 4-2. The connection hole 4-3 can be a circular hole. By passing a bolt through the first bolt hole 2-4 and the connection hole 4-3 and locking it with a nut, the fixation of the rain-proof cap support 4 and the connection leg 2-2 can be achieved, and the connection is firm. The "L"-shaped rain-proof cap support 4 can hold the rain-proof cap 3 at a higher position, forming a side ventilation window 6 below, which is convenient for the convection of internal and external air. To facilitate the connection between the rain-proof cap support 4 and the rain-proof cap 3, a bending part 4-1a for welding with the inner wall of the rain-proof cap 3 is also provided at the upper end of the vertical section 4-1. The bending part 4-1a can better adapt to the inner wall angle of the rain-proof cap 3 and ensure the welding firmness. So far, the rain-proof cap 3 and the rain-proof cap support 4 form an integral module, and the inner support 2 of the level gauge and the outer sleeve 1 of the level gauge form another integral module. The two modules are connected by bolts. This modular design is convenient for installation and maintenance, reducing the operation difficulty and cost.

[0043] Return Figure 1 As shown in the figure, for the rain-proof and breathable device of the mud line silo level gauge in this embodiment, the outer sleeve 1 of the level gauge is a hollow cylindrical shape with both ends open, and the rain-proof cap 3 is a conical shape with a smaller upper part and a larger lower part, with a simple structure and convenient production. Of course, in this embodiment, it is not limited to the above shapes. For example, the outer sleeve 1 of the level gauge can also be a square tube, etc., and the rain-proof cap 3 can also be a quadrangular pyramid, a hemispherical shape, etc. In this embodiment, the diameter D2 of the brim of the rain-proof cap 3 is twice or more than twice the outer diameter D1 of the outer sleeve 1 of the level gauge, so that the rain-proof cap 3 can fully cover the upper part of the outer sleeve 1 of the level gauge, reducing the situation of oblique wind and rain hitting the inside. Preferably, the number of the rain-proof cap supports 4 is the same as the number of the connection legs 2-2 on the inner support 2 of the level gauge. There are at least two connection legs 2-2 evenly distributed on the outer circumference of the central ring 2-1 of the inner support 2 of the level gauge. For example Figure 2 and Figure 3 both preferably set 4 connection legs 2-2 and 4 rain-proof cap supports 4, taking into account both the structural firmness and breathability of the device.

[0044] [Embodiment 2]

[0045] A rain-proof and breathable device for a mud line silo level gauge in this embodiment has the same basic structure and working principle as Embodiment 1, and the differences are as follows:

[0046] As Figure 5As shown, in this embodiment, the connection hole 4-3 at the lower part of the rain-proof cap support 4 is a U-shaped hole. The U-shaped hole can extend along the radial direction of the rain-proof cap 3, facilitating fine adjustment of the connection position, making it more convenient for the connection hole 4-3 to align with the bolt hole 2-4 on the connection leg 2-2, and facilitating assembly. Of course, the connection hole 4-3 can also be a waist-shaped hole with a similar effect.

[0047] As Figure 2 and Figure 3 shown, in this embodiment, a number of bolt holes 2-5 for bolt connection with the flange of the level gauge are also provided on the central ring 2-1. For the flange of a small-sized level gauge, the bolt holes 2-5 can be used for connection. In this way, combined with the above-mentioned connection method between the bolt hole 2-4 and the flange of the level gauge, different specifications of level gauge flanges can be flexibly adapted, enhancing the versatility and adaptability of the device.

[0051] 3. Stable structure and convenient installation: Components such as the outer sleeve of the level gauge, the inner support, and the rain-proof cap support are reasonably designed and connected by welding and bolt fixation, etc. The overall structure is firm and reliable. At the same time, this modular design is convenient for installation and maintenance, reducing the operation difficulty and cost.

[0052] 4. Flexibility and adaptability: The ring design on the inner support of the level gauge is also provided with bolt holes, which can flexibly adapt to different specifications of level gauge flanges, enhancing the versatility and adaptability of the device. In addition, the design of the connection support allows the rain-proof cap support and the level gauge to be fixed simultaneously, improving the installation efficiency and stability.

[0053] 5. Improve the equipment maintenance efficiency: Since part of the structure of the level gauge extends outside the silo, it makes daily inspection and maintenance more convenient and fast, reducing the maintenance difficulty and cost, and improving the overall operation efficiency.

[0054] 6. Environmental protection and economy: By effectively extending the service life of the level gauge, the resource waste caused by frequent equipment replacement is reduced, which conforms to the concept of energy conservation and environmental protection.

[0055] In summary, the rainproof and breathable device for the mud line silo level gauge of the present utility model shows significant beneficial effects in aspects such as protecting the level gauge, preventing rain erosion, improving equipment stability and maintenance efficiency, and has high practical value and popularization significance.

[0056] The above schematically describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the purpose of the present utility model, they shall fall within the protection scope of the present utility model.
