Description

Technical Field

[0001] The utility model relates to the technical field of dust removal pipelines, in particular to a novel dust removal pipeline elbow. Background Art

[0002] Dust removal ducts are typically pre-set pipes connected to dust removal equipment to direct the flow of dust, smoke, or powder. Common dust removal ducts are steel or iron pipes, installed in the workshop along a predetermined path based on the specific structure of the workshop. In steel mills, in addition to dust, dust removal ducts also contain small amounts of iron powder or iron slag. This iron powder or iron slag is driven by compressed air and has a height difference. When it flows to the elbow of the dust removal duct, due to the need to turn, the iron powder or iron slag will impact the outer bend of the elbow. Prolonged impact can cause damage to the outer bend of the dust removal duct, which can then form a hole in the outer bend of the elbow. Dust, iron powder, and iron slag will fly out of the hole, polluting the surrounding environment.

[0003] The conventional solution is to weld a steel plate over the leak to plug it. However, after the dust removal equipment has been used for a period of time, the leak will reappear, requiring further repairs. This repetitive process not only increases production costs but also consumes a lot of man-hours, which will have a long-term impact on system operation. Utility Model Content

DETAILED DESCRIPTION

[0018] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] See also Figures 1 to 4The embodiment of the present application provides a new type of dust removal pipe elbow, including a bend pipe body 1, a wear-resistant baffle 2 and a fastening device 3. The side wall of the inlet end of the bend pipe body 1 is provided with an installation opening 4, and the installation opening 4 is slidingly and sealably installed with an inclined wear-resistant baffle 2. The fastening device 3 is installed on the bend pipe body 1, and the wear-resistant baffle 2 is detachably connected to the installation opening 4 through the fastening device 3. The length of the wear-resistant baffle 2 inserted into the bend pipe body 1 is adjusted by the fastening device 3.

[0020] Specifically, the fastening device 3 includes a fixing base 5, a bolt 6, a nut 7, and a fastening block 8. The fixing base 5 is fixedly connected to the outer wall of the elbow body 1, the nut 7 is fixedly installed on the fixing base 5, the bolt 6 is threadedly connected to the nut 7, and one end of the bolt 6 abuts against the fastening block 8. The fastening block 8 is pressed between the elbow body 1 and the wear-resistant baffle 2 by the bolt 6. By first placing the fastening block 8 on the wear-resistant baffle 2 and then rotating the bolt 6 so that the bolt 6 contacts the fastening block 8, the fastening block 8 is gradually tightened, and the fastening block 8 presses the wear-resistant baffle 2 to the elbow body 1 through friction.

[0021] In order to facilitate the fastening block 8 to stably press and fix the wear-resistant baffle 2 on the elbow body 1, the fastening block 8 is provided to include a first end face 9, a second end face 10 and a third end face 11. The first end face 9 is used to contact and cooperate with the bottom of the elbow body 1, the second end face 10 is used to contact and cooperate with the wear-resistant baffle 2, and the third end face 11 is used to contact and cooperate with the bolt 6. In the process of pressing and fixing the wear-resistant baffle 2 on the elbow body 1, the fastening block 8 is placed on the wear-resistant baffle 2, and the second end face 10 is in contact with the wear-resistant baffle 2. By rotating the bolt 6 so that the end of the bolt 6 away from the screw head is in contact with the third end face 11, the bolt 6 pushes the fastening block 8 to slide on the wear-resistant baffle 2 until the first end face 9 abuts against the elbow body 1, so that the fastening block 8 stably presses and fixes the wear-resistant baffle 2 on the elbow body 1.

[0022] To ensure the stability of the fastening block 8 and prevent relative movement between the fastening block 8 and the elbow body 1, the first end surface 9 is configured as an arcuate surface that aligns with the sidewall of the inlet end of the elbow body 1. This arcuate surface prevents the fastening block 8 from moving radially relative to the elbow body 1, i.e., in the Y-axis direction, after being pressed against the wear-resistant baffle 2. Furthermore, the bolt 6 restricts the fastening block 8 from moving in the X-axis direction, while the wear-resistant baffle 2 and the elbow body 1 jointly restrict the fastening block 8 from moving in the Z-axis direction. Thus, the fastening block 8 remains stable.

[0023] The elbow body 1 includes an inlet straight pipe section 12, an elbow section 13, and an outlet straight pipe section 14, which are connected in sequence. The angle between the inlet straight pipe section 12 and the outlet straight pipe section 14 is a, 90°≤a<180°. The installation port 4 and the fastening device 3 are both located at the inlet straight pipe section 12. In this embodiment, a is set to 90°.

[0024] The included angle between the wear-resistant baffle 2 and the inlet straight pipe section 12 is b, where 0° < b ≤ 45°. The larger the value of b, the greater the resistance to the air flow inside the elbow body 1, the greater the impact of dust and other impurities, and the faster the wear, so it should not be too large; the value of b should not be too small either. The smaller the value of b, the greater the difficulty of processing and installing the opening 4, and the maximum insertion length of the wear-resistant baffle 2 will also be limited. In this embodiment, b is set to 30°.

[0025] The working principle of this embodiment: Since the elbow section 13 has a certain angle, it is most vulnerable to wear during ventilation work. By installing the wear-resistant baffle 2 at the inlet straight pipe section 12, it can replace part of the elbow section 13 to bear the impact of dust and other impurities, and reduce the wear of the elbow section 13;

[0026] By regularly checking the wear condition of the wear-resistant baffle 2, flexibly adjusting the length inserted into the elbow body 1, and then fixing the wear-resistant baffle 2 through the fastening device 3, the whole process takes a short time and will not cause a long-term impact on the system operation; by protecting the elbow section 13 through the wear-resistant baffle 2, the wear of the elbow section 13 can be reduced, and the service life of the elbow body 1 can be extended. It is also possible to count according to the wear condition of the wear-resistant baffle 2. After obtaining the wear law, only need to regularly increase the length of the wear-resistant baffle 2 inserted into the elbow body 1, so that the wear amount of the wear-resistant baffle 2 inside the elbow body 1 can be replenished, and the length of the wear-resistant baffle 2 inserted into the elbow body 1 can be kept roughly constant without stopping work, thereby improving production efficiency.

[0027] By adjusting the length of the wear-resistant baffle 2 inserted into the elbow body 1, the protection area of the wear-resistant baffle 2 for the elbow section 13 can be adjusted. For example, when the elbow section 13 at a position closer to the inlet straight pipe section 12 is severely worn, the length of the wear-resistant baffle 2 inserted into the elbow body 1 can be increased, so that the protection area of the wear-resistant baffle 2 covers the worn area of the elbow section 13 at a position closer to the inlet straight pipe section 12, thereby extending the service life of the elbow body 1.

[0028] It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
