Description

Technical Field

[0001] The invention belongs to the technical field of mining, and in particular relates to a rotary slurry pipeline dredging head. Background Art

[0002] In the mining industry, slurry needs to be transported through pipelines. To make the pipelines run more smoothly, they need to be cleaned and unblocked regularly. At present, there are some tools on the market that can assist in unblocking pipelines, but their ability to remove scale on the inner wall of the pipeline is limited, making it difficult to ensure the efficiency and effect of unblocking pipelines. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a rotary slurry pipeline dredging head so as to improve the efficiency and effect of pipeline dredging.

[0004] The present invention solves the above problems by the following technical means:

[0005] The present invention provides a rotary slurry pipeline dredging head, comprising a fixed seat, a rotating body and a rotating shaft, wherein the rotating body is rotatably assembled with the fixed seat, and the rotating shaft is fixedly assembled at one end of the rotating body; a water inlet channel is opened at the center of the fixed seat, and a plurality of downwardly inclined jet channels are evenly opened in the circumferential direction of the side wall of the rotating body, and the high end of the jet channel is connected with the water inlet channel; a scraper is arranged on the rotating shaft.

[0006] Furthermore, a sleeve is provided on the rotating shaft, the scraper is slidably assembled with the sleeve, and one end of the scraper located in the sleeve is connected to the inner wall of the sleeve through a spring.

[0007] Furthermore, a distribution cavity is provided at the end of the water inlet channel, and the jet channel is communicated with the distribution cavity.

[0008] Furthermore, the rotating body is rotatably assembled with the fixing seat via a bearing.

[0009] Furthermore, the rotating shaft is threadedly connected to the rotating body.

[0010] Furthermore, the jet channel has an inclination angle of 40°-75°.

[0011] Beneficial effects of the present invention:

[0012] The present application discloses a rotary slurry pipeline dredging head, comprising a fixed seat, a rotating body and a rotating shaft, wherein the rotating body is rotatably assembled with the fixed seat, and the rotating shaft is fixedly assembled at one end of the rotating body; a water inlet channel is provided at the center of the fixed seat, and a plurality of jet channels inclined downward are evenly provided on the side wall of the rotating body in the circumferential direction, and the high end of the jet channel is connected with the water inlet channel; a scraper is provided on the rotating shaft. When working, the water inlet channel is externally connected to a high-pressure water pipe, and a reaction force is generated by the high-pressure jet, wherein the axial component forces the dredging head to move forward in the pipeline, and the radial component forces can make the dredging head suspend in the middle position of the pipeline, and at the same time can cause the rotating body and the rotating shaft to rotate, thereby driving the scraper to rotate, which can not only break up the blockage, but also scrape off the scale on the inner wall of the pipeline. In addition, the ejected high-pressure water flow can also clean the inner wall of the pipeline, thereby improving the efficiency and effect of pipeline dredging. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Figure 1 It is a schematic structural diagram of a preferred embodiment of the present invention. DETAILED DESCRIPTION

[0015] The present invention is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present invention will become clearer and more specific. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0016] like Figure 1 As shown, this embodiment discloses a rotary slurry pipe clearing head, including a fixed seat 1, a rotating body 4 and a rotating shaft 6, the rotating body is rotatably assembled with the fixed seat, and the rotating shaft is fixedly assembled at one end of the rotating body; in this embodiment, the rotating body is rotatably assembled with the fixed seat through a bearing 3, and the rotating shaft is threadedly connected to the rotating body, and the thread rotation direction is opposite to the rotation direction of the rotating body.

[0017] A water inlet channel 2 is provided at the center of the fixed seat, and a plurality of downwardly inclined jet channels 5 are evenly provided on the circumferential side walls of the rotating body, and the high end of the jet channel is connected to the water inlet channel, and the inclination angle of the jet channel is 40°-75°; preferably, a distribution chamber 10 is provided at the end of the water inlet channel, and the jet channel is connected to the distribution chamber, and the water flow is distributed through the distribution chamber, which can improve the uniformity of the water flow in each jet channel.

[0018] The rotating shaft is provided with a scraper 8; preferably, the rotating shaft is provided with a sleeve 7, the scraper is slidably assembled with the sleeve, and one end of the scraper located in the sleeve is connected to the inner wall of the sleeve through a spring 9. In this way, the scraper can be elastically retracted, so that the scraping radius can be adaptively adjusted.

[0019] During operation, the water inlet channel is connected to a high-pressure water pipe, and a reaction force is generated through the high-pressure jet. The axial component of force prompts the dredging head to move forward in the pipe, and the radial component of force can make the dredging head float in the middle of the pipe, and at the same time prompt the rotating body and the rotating shaft to rotate, thereby driving the scraper to rotate, which can not only break up the blockage, but also scrape off the scale on the inner wall of the pipe. In addition, the ejected high-pressure water flow can also clean the inner wall of the pipe, thereby improving the efficiency and effect of pipe dredging.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
