At present, the on-off pressure of the air supplementing dredging device (because of the communication between the air supplementing dredging device and the material conveying pipeline, the pressure is consistent with the pressure inside the material conveying pipeline) cannot be adjusted according to the suitability of a use field, and the existing defects are that: if the opening and closing pressure is too high, the opening (air supplementing) of the air supplementing dredging device is not timely, so that the timeliness of pipeline dredging is influenced; if the opening and closing pressure is too small, the air supplementing dredging device can be frequently opened to waste compressed air, so that the pipeline dredging cost is increased.
Disclosure of Invention
Therefore, the utility model aims to provide the pipeline anti-blocking automatic air-supplementing dredging device for pneumatic conveying, so that the opening and closing pressure of the air-supplementing dredging device can be adaptively adjusted according to the use situation, and the timeliness of opening and closing and the rationality of opening and closing are both considered.
The utility model solves the problems by the following technical means: the utility model provides an automatic air make-up pull throughs of pipeline anti-blocking for pneumatic conveying, includes base, shell, core, pressure adjusting bolt and spring, through bolt fixed assembly between base and the shell, be connected with air make-up intake pipe and air make-up outlet duct on the base, the core sets up in the base, pressure adjusting bolt penetrates in the shell and with shell threaded connection, the spring sets up in the shell and is in between pressure adjusting bolt and the core.
Further, a nut is fixedly arranged on the shell, and the pressure adjusting bolt penetrates through the nut and is in threaded connection with the nut.
Further, one end of the pressure adjusting bolt, which is positioned in the shell, is fixedly provided with a pressing plate, and the spring is positioned between the pressing plate and the core body.
Further, a sealing ring and a sealing gasket are respectively assembled on the sealing end face between the core body and the base.
Further, the nut is welded and fixed with the shell.
Further, the shell and the base are assembled in a butt joint mode through the boss, and assembly locking is achieved through the bolts.
The utility model has the beneficial effects that:
the utility model discloses an anti-blocking automatic air supplementing and dredging device for a pneumatic conveying pipeline, which comprises a base, a shell, a core body, a pressure adjusting bolt and a spring, wherein the base and the shell are fixedly assembled through bolts, the base is connected with an air supplementing inlet pipe and an air supplementing outlet pipe, the core body is arranged in the base, the pressure adjusting bolt penetrates into the shell and is in threaded connection with the shell, and the spring is arranged in the shell and is positioned between the pressure adjusting bolt and the core body. The automatic air supplementing dredging device can adaptively adjust the opening and closing pressure according to the use situation, so that the opening and closing timeliness and the opening and closing rationality are considered.
Drawings
The utility model is further described below with reference to the drawings and examples.
Fig. 1 is a schematic structural view of a preferred embodiment of the present utility model.
Detailed Description
The present utility model will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments are shown, for the purpose of illustrating the utility model, but the scope of the utility model is not limited to the specific embodiments shown.
As shown in fig. 1, the embodiment provides an anti-blocking automatic air supplementing and dredging device for a pneumatic conveying pipeline, which comprises a base 8, a shell 2, a core 6, a pressure adjusting bolt 13 and a spring 3; the base and the shell are fixedly assembled through bolts 4, and in the embodiment, the shell and the base are assembled in a butt joint mode through bosses 14 and are assembled and locked through bolts; the base is connected with an air supplementing air inlet pipe 9 and an air supplementing air outlet pipe 11, the core body is arranged in the base, a sealing ring 5 and a sealing gasket 7 are respectively assembled on the sealing end face between the core body and the base, wherein the sealing ring is used for preventing air from flowing into the shell, and the sealing gasket is used for guaranteeing the closing reliability of the core body; the pressure adjusting bolt penetrates into the shell and is in threaded connection with the shell, and in the embodiment, a nut 1 is fixedly arranged on the shell in a welded mode, and the pressure adjusting bolt penetrates through the nut and is in threaded connection with the nut; the spring is arranged in the shell and is positioned between the pressure adjusting bolt and the core body, in the embodiment, a pressing plate 10 is fixedly arranged at one end of the pressure adjusting bolt positioned in the shell, and the spring is positioned between the pressing plate and the core body.
When the high-pressure air supplementing device is applied, the air supplementing air inlet pipe is communicated with the compressed air supply end, the air supplementing air outlet pipe is communicated with the material conveying pipeline 12, when the material conveying pipeline is not blocked, the core body seals the air supplementing air outlet pipe under the action of the elastic force of the spring, when the material conveying pipeline is blocked, the pressure of the core body rises, the core body is pushed to be opened, and the air supplementing air inlet pipe is communicated with the air supplementing air outlet pipe through air flow, so that the blocked material can be blown away through high-pressure air supplementing. The opening and closing pressure of the core body 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 adjusting bolt, so that the automatic air supplementing dredging device can be used for adaptively adjusting the opening and closing pressure according to the use situation, and the timeliness of opening and closing and the rationality of opening and closing are considered.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present utility model, which is intended to be covered by the scope of the claims of the present utility model.
