Description

An automatic air supply and dredging device for preventing clogging of pipelines used in pneumatic transportation

Technical field

The utility model belongs to the technical field of pipeline transportation, and specifically relates to an anti-clogging automatic air supply and dredging device for pipelines used for pneumatic transportation.

Background technique

In the transportation process of granular materials and powders in the fields of thermal power, metallurgy, chemical industry, construction and other fields, pneumatic pipeline transportation is often used, which inevitably leads to the problem of material pipe blocking. At present, most of the ways to solve this problem are to install additional equipment on the material transportation pipelines. Compressed air supply and dredging device. When the pipe is blocked, a large amount of high-pressure gas is filled into the material conveying pipe through the air supply and dredging device to blow away the blocked material and make the pipe unblocked.

The opening and closing pressure of the current air supply and dredging device (because it is connected to the material conveying pipeline, so the pressure is consistent with the pressure inside the material conveying pipeline) cannot be adjusted adaptively according to the use occasion. The disadvantage is: if the opening and closing pressure is too high If the opening and closing pressure is too small, it may cause the air supply and dredging device to open frequently and waste compressed air, thereby increasing the cost of pipeline dredging.

Timeliness and reasonableness of opening and closing.

The utility model solves the above problems through the following technical means: a pipeline anti-clogging automatic air supply and dredging device for pneumatic transportation, including a base, a shell, a core, a pressure adjustment bolt and a spring. Bolts are used between the base and the shell. Fixed assembly, the base is connected with the air inlet pipe and the air outlet pipe, the core is set in the base, the pressure adjustment bolt penetrates into the shell and is threadedly connected to the shell, the spring is set in the shell and is in Between the pressure adjustment bolt and the core.

Further, a nut is fixedly provided on the housing, and the pressure adjustment bolt passes through the nut and is threadedly connected to the nut.

Further, a pressure plate is fixed to one end of the pressure adjustment bolt located in the housing, and the spring is located between the pressure plate and the core.

Furthermore, sealing rings and sealing pads are respectively installed on the sealing end surfaces between the core body and the base.

Further, the nut and the shell are welded and fixed.

Further, the shell and the base are assembled through a boss and assembled and locked through bolts.

Beneficial effects of this utility model:

The anti-clogging automatic air supply and dredging device for pipelines used in this application for pneumatic transportation includes a base, a shell, a core, a pressure adjustment bolt and a spring. The base and the shell are fixed and assembled by bolts, and the base is connected to an air supply inlet. The air pipe and the air supply outlet pipe, the core body is arranged in the base, the pressure adjustment bolt penetrates into the shell and is threadedly connected to the shell, the spring is arranged in the shell and is between the pressure adjustment bolt and the core body. Using the automatic air supply and dredging device of the present application, its opening and closing pressure can be adaptively adjusted according to the use occasion, thereby taking into account the timeliness of opening and closing and the rationality of opening and closing.

Description of the drawings

The utility model will be further described below in conjunction with the accompanying drawings and examples.

Figure 1 is a schematic structural diagram of a preferred embodiment of the present utility model.

Detailed ways

In order to facilitate understanding of the present utility model, the present utility model will be described more comprehensively and in detail below in conjunction with the accompanying drawings and preferred embodiments of the specification. However, the protection scope of the present utility model is not limited to the following specific embodiments.

As shown in Figure 1, this embodiment provides an automatic air supply and dredging device for pipeline anti-clogging for pneumatic transportation, including a base 8, a shell 2, a core 6, a pressure adjustment bolt 13 and a spring 3; the base and The shells are fixed and assembled through bolts 4. In this embodiment, the shell and the base are butt assembled through bosses 14 and the assembly is locked through bolts; the base is connected to a supplementary air inlet pipe 9 and a supplementary air outlet. Trachea 11, the core body is arranged in the base, and the sealing end surface between the core body and the base is equipped with a sealing ring 5 and a sealing gasket 7 respectively. The sealing ring is used to prevent gas from flowing into the shell, and the sealing gasket is used to ensure that the core The reliability of body closing; the pressure adjustment bolt penetrates into the housing and is threadedly connected to the housing. In this embodiment, a nut 1 is welded and fixed on the housing, and the pressure adjustment bolt passes through the nut and is connected with the nut. The cap is threaded; the spring is arranged in the casing and between the pressure adjustment bolt and the core. In this embodiment, the pressure adjustment bolt is fixedly provided with a pressure plate 10 at one end of the casing, and the spring is between the pressure plate and the core. between bodies.

When used, the air supply inlet pipe is connected to the compressed gas supply end, and the air supply outlet pipe is connected to the material conveying pipe 12. When the material conveying pipe is not blocked, under the action of spring elasticity, the core body closes the air supply outlet pipe, and when the material is conveyed When the pipeline is clogged, the pressure inside it increases, pushing the core to open, and the air flow between the air supply inlet pipe and the air supply outlet pipe is connected, and the blocked materials can be blown away through high-pressure air supply. The opening and closing pressure of the core can be adjusted by adjusting the compression amount of the spring, and the compression amount of the spring can be adjusted by rotating the pressure adjustment bolt. Therefore, the automatic air supply and dredging device of the present application can be used according to the use occasion. The opening and closing pressure is adaptively adjusted, thus taking into account the timeliness of opening and closing and the rationality of opening and closing.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the present utility model can be modified. If the technical solution is modified or equivalently substituted without departing from the purpose and scope of the technical solution of the present utility model, it shall be covered by the claims of the present utility model.
