Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a self-cleaning dust conveying pipeline. Background Art

[0002] Dust will be generated during the processing of powder products, as well as in the production processes of metallurgy and brick making. This will lead to a large amount of dust in the production workshop, posing a safety hazard of dust explosion. At the same time, a large amount of dust will seriously affect the health and vision of workers in the workshop. Therefore, dust removal devices are usually used to remove dust from the workshop.

[0003] After searching, the patent with publication number CN117531311A discloses a dust removal system and a dust removal method. The dust in the workshop is transported and discharged by setting a dust removal pipe and an induced draft fan. However, in actual use, it is found that the length of the dust removal pipe is relatively long. During the dust transportation process, due to the suction force or the obstruction at the elbow of the pipe, a large amount of dust hits the inside of the pipe and accumulates. Long-term operation will affect the transportation of dust. The existing dust transportation pipe generally has a cleaning port at a certain interval. It is necessary to manually climb to a high place to open the cover of the cleaning port, and then extend the cleaning tool into the pipe for cleaning. It is time-consuming and labor-intensive, and the cleaning efficiency is low. Manual cleaning involves climbing work, which poses a safety risk. Utility Model Content

[0004] In order to solve the problems of low efficiency and high safety risks of existing manual cleaning, the utility model provides a self-cleaning dust conveying pipeline. By arranging a dust removal pipe in the conveying pipeline, the dust accumulated at the bottom of the pipeline is blown away, which effectively avoids dust accumulation and ensures smooth dust transportation.

[0005] The utility model provides a self-cleaning dust conveying pipeline, which is provided with an air extraction port and / or an air filling port, so that an air flow is formed in the conveying pipeline, and a plurality of dust removal pipes are arranged in the conveying pipeline, one end of the dust removal pipe is connected to an external air pump, and the other end extends into the conveying pipeline and is placed near the bottom of the conveying pipeline, and the plurality of dust removal pipes are arranged along the length direction of the conveying pipeline. The air pump conveys gas into the conveying pipeline through the dust removal pipe, so as to realize the purge of dust accumulated in the conveying pipeline and avoid dust accumulation.

[0006] Furthermore, a mounting hole for the dust removal pipe to pass through is provided at the bottom of the conveying pipeline, and a sealing ring is provided between the dust removal pipe and the mounting hole. The mounting hole position is sealed by the sealing ring to fix the dust removal pipe.

[0007] Furthermore, a bracket is provided at one end of the dust removal pipe away from the mounting hole, and the dust removal pipe is fixedly arranged in the conveying pipeline through the bracket. Since the dust removal pipe is long, the end portion is easy to fall, and is supported by the bracket.

[0008] Furthermore, the bracket includes a horizontal plate radially arranged in the conveying pipeline, the horizontal plate is clamped in the conveying pipeline, and the end of the dust removal pipe is placed on the horizontal plate. The dust removal pipe is erected by the horizontal plate clamped in the conveying pipeline to ensure that the end does not fall.

[0009] Furthermore, one end of the dust removal pipe extending into the conveying pipe is in a closed state, and a plurality of air holes are arranged at the bottom of the dust removal pipe, and the plurality of air holes are arranged at equal intervals along the length direction of the dust removal pipe. The dust in the conveying pipe is purged through the air holes at the bottom of the dust removal pipe.

[0010] Furthermore, a plurality of air holes form a row of hole groups, and the hole groups are arranged directly below the dust removal pipe. The air holes arranged directly below have a greater blowing intensity on the dust at the bottom of the pipe.

[0011] Furthermore, the plurality of air holes form two rows of hole groups, which are symmetrically arranged at the lower part of the dust removal pipe, and the hole groups are arranged at an acute angle to the center line. The hole groups are arranged at a certain angle to prevent dust from being raised and clogging the air holes.

[0012] Furthermore, the hole group is arranged at an angle of 0 to 30° with the center line. The angle can be selected and set according to actual purging requirements.

[0013] The beneficial effects of the utility model are:

[0014] The utility model provides a self-cleaning dust conveying pipeline. By arranging dust removal pipes at equal intervals in the conveying pipeline, the dust accumulated at the bottom of the pipeline can be blown away, and the raised dust is just taken away by the airflow.

[0021] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] The existing dust conveying pipe 1 generally has a cleaning port at a certain interval, and it is necessary to manually climb to a high place to open the cover of the cleaning port, and then insert a cleaning tool into the pipe for cleaning, which is time-consuming and labor-intensive, and has low cleaning efficiency. In order to facilitate the cleaning of dust accumulation in the dust conveying pipe 1, a self-cleaning dust conveying pipe is designed, such as Figure 1 As shown, an air suction port and / or an air charging port are provided to form an air flow in the conveying pipeline 1, a plurality of dust removal pipes 2 are arranged in the conveying pipeline 1, a mounting hole for the dust removal pipe 2 to pass through is arranged at the bottom of the conveying pipeline 1, a sealing ring is arranged between the dust removal pipe 2 and the mounting hole to ensure the sealing, one end of the dust removal pipe 2 is connected to an external air pump, and the other end extends into the conveying pipeline 1 and is placed near the bottom of the conveying pipeline 1, and a plurality of dust removal pipes 2 are arranged along the length direction of the conveying pipeline 1.

[0023] Several air pumps are electrically connected to the remote controller, and the controller controls the on and off of the air pumps. The air pumps are started to input gas into the dust removal pipe 2. The gas enters the conveying pipe 1 along the dust removal pipe 2 and is ejected from the air hole 4, blowing up the dust accumulated in the pipe. The raised dust is then carried away by the airflow in the conveying pipe 1, thereby ensuring the cleanliness of the inside of the conveying pipe 1 and improving the dust conveying efficiency. In order to save energy consumption, the air pumps can be turned on at intervals, or multiple air pumps can be divided into two groups that are alternately set and connected to two control lines respectively, and then alternately sprayed.

[0024] like Figure 2 As shown, since the dust removal pipe 2 is long, the end of the pipe is prone to fall down when used for a long time without support. In order to prevent the end of the dust removal pipe 2 from falling down, a bracket 3 is provided at one end of the dust removal pipe 2 away from the mounting hole, and the dust removal pipe 2 is fixedly arranged in the conveying pipe 1 through the bracket 3. One end of the dust removal pipe 2 is fixed at the mounting hole of the conveying pipe 1 to form a first fulcrum, and the other end of the dust removal pipe 2 is hung on the bracket 3 to form a second fulcrum to ensure the stability of the purge.

[0025] In order not to block the dust transportation, the bracket 3 adopts a horizontal plate radially arranged in the conveying pipeline 1, the horizontal plate is clamped in the conveying pipeline 1, and the dust removal pipe 2 is mounted on the horizontal plate. The horizontal plate can be clamped or welded to the conveying pipeline 1.

[0026] In order to clean the dust accumulated at the bottom of the conveying pipe 1, one end of the dust removal pipe 2 extending into the conveying pipe 1 is in a closed state, and a plurality of air holes 4 are arranged at the bottom of the dust removal pipe 2, and the plurality of air holes 4 are arranged at equal intervals along the length direction of the dust removal pipe 2. When the external air pump is started, gas is introduced into the dust removal pipe 2, and the gas is ejected from the air holes to sweep the dust accumulated at the bottom of the conveying pipe 1, and the dust is lifted up and carried away by the airflow in the conveying pipe 1.

[0027] In the first embodiment, in order to ensure the purging effect of the dust accumulated at the bottom, a plurality of air holes 4 form a row of hole groups, and the hole groups are arranged directly below the dust removal pipe 2. The gas is blown directly toward the dust accumulated at the bottom, and the purging effect is good.

[0028] In the second embodiment, in order to further ensure the purging effect of the accumulated dust, a plurality of air holes 4 form two rows of hole groups, and the two rows of hole groups are symmetrically arranged at the lower part of the dust removal pipe 2, and the hole groups are arranged at an acute angle with the center line. Specifically, the hole groups are arranged at an angle of 0 to 30 degrees with the center line. The dust that is purged may enter the air holes 4 and cause the air holes 4 to be blocked, so the air holes 4 can be tilted at a certain angle to ensure that the dust accumulated at the bottom of the pipe is blown up while effectively preventing the air holes from being blocked.

[0029] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the appended claims, but all will fall within the scope of protection of the present invention.
