Description

Technical Field

[0001] This utility model relates to the field of phosphate rock slurry technology, specifically a descaling device for phosphate rock slurry conveying pipelines. Background Technology

[0002] Phosphate slurry is a high-concentration slurry formed after phosphate rock is crushed and ground. It is a key intermediate product in phosphate ore beneficiation and processing. Its core use is as a raw material for beneficiation processes such as flotation, ultimately producing phosphate fertilizers or phosphate chemical products.

[0003] Existing technology discloses a pipe descaling device with application number CN220547413U, comprising: a fixed rod; a scraper movably connected to one end of the fixed rod; and a pull rod disposed on one side of the fixed rod, one end of which is hinged to the scraper. The pull rod can drive the scraper to rotate around the connection point between the scraper and the fixed rod, so that the scraper is in a first position or a second position relative to the fixed rod. In the first position, the scraper coincides with the axis of the fixed rod; in the second position, the scraper and the fixed rod form a set angle. This utility model allows for convenient placement of the pipe descaling device into the pipe. When cleaning is required, the scraper is unfolded to clean the inner wall of the pipe, and the scraped dirt is moved to the pipe opening by the movement of the fixed rod, facilitating the discharge of dirt. This solves the problem of small descaling area in damp pipes and difficulty in removing scraped dirt, reducing the risk of dirt contaminating the equipment rollers.

[0004] One end of the aforementioned pull rod is hinged to the scraper. The pull rod can drive the scraper to move on the inner wall surface of the pipe, allowing the scraper to scrape the inner wall surface of the pipe. However, when the scraper scrapes, it can easily damage the pipe, causing the pipe to be unable to effectively transport phosphate slurry. Utility Model Content

The connecting rod and the connecting slide rod determine the position of the connecting ring and prevent the connecting ring from shaking.

[0013] Preferably, the fastening threaded rods are divided into two groups, which are distributed at the left and right ends of the metal arm. The fastening threaded rod on the left is inserted into the right end of the connecting ear, and the fastening threaded rod on the right is inserted into the outward end of the connecting block.

[0031] The scraping device 1 includes a connecting rod 11, a reinforcing component 13 is bolted to the left side surface of the connecting rod 11, and a connecting slide rod 12 is threaded to the right end of the connecting rod 11.

[0032] The reinforcing component 13 includes a scraping ring 131 and a connecting slide rod 12 slidably connected to the middle position of the connecting housing 3. The connecting slide rod 12 slides in the middle position of the connecting housing 3, allowing the connecting slide rod 12 to push the connecting rod 11 and the scraping ring 131 to move, so that the scraping ring 131 scrapes the inner wall surface of the conveying pipe body 2. The scraping ring 131 is slidably connected to the inner wall surface of the conveying pipe body 2, and the scraping ring 131 scrapes the inner wall of the conveying pipe body 2. The scraping ring 131 performs scraping operation on the phosphate rock slurry on the inner wall surface of the conveying pipe body 2.

[0033] A connecting lug 132 is welded to the right side surface of the scraping ring 131. The connecting rod 11 is threaded to the middle position of the connecting plate 138. The connecting rod 11 can be disassembled at the center of the connecting plate 138, making it easy to disassemble and replace the connecting rod 11. Different specifications of connecting rod 11 can be used.

[0034] A connecting plate 138 is welded to the right end of the scraping ring 131. The connecting rod 11 is threaded to the middle position of the connecting plate 138. The connecting rod 11 can be disassembled at the center of the connecting plate 138, which makes it easy to disassemble and replace the connecting rod 11. Different specifications of connecting rod 11 can be used.

[0035] A metal arm 135 is bolted to the right end of the connecting ear 132. There are six metal arms 135 arranged in a ring. The six metal arms 135 determine the position of the scraping ring 131 and keep the scraping ring 131 stable. Fastening threaded rods 137 are inserted into the left and right ends of the metal arms 135. A connecting block 136 is threaded to the right end of the metal arm 135. The fastening threaded rods 137 are divided into two groups, which are distributed at the left and right ends of the metal arm 135. The fastening threaded rod 137 on the left end is inserted into the right end of the connecting ear 132, and the fastening threaded rod 137 on the right end is inserted into the outward end of the connecting block 136. The fastening threaded rods 137 lock and fix the connecting ear 132, the metal arm 135 and the connecting block 136.

[0036] A connecting ring 134 is welded to the inner surface of the connecting block 136. A metal plate is welded to the left side surface of the connecting slide rod 12. The metal plate is connected to the right side surface of the connecting ring 134. The threaded rod 133 is inserted and locked to the connecting ring 134 and the connecting slide rod 12 through the metal plate. The connecting rod 11 is inserted into the inner wall surface of the connecting ring 134. The connecting ring 134 is threaded to the left side surface of the connecting slide rod 12.

[0039] The scraping ring 131 slides on the inner wall surface of the conveying pipe body 2, and scrapes off the residual phosphate rock slurry on the inner wall surface of the conveying pipe body 2, keeping the inner wall surface of the connecting shell 3 clean.

[0040] After the scraping inside the conveying pipe body 2 is completed, rotate the bolt to disengage the bolt from the connection between the connecting shell 3 and the conveying pipe body 2.

[0041] Pull the connecting slide rod 12 to the right. The connecting slide rod 12 drives the scraping ring 131 to move to the right through the connecting rod 11. The scraping ring 131 moves the scraped residue to the right, allowing the residue to detach from the conveying pipe body 2. This makes it easier to maintain the scraping ring 131.
