Moreover, the double rolling setting between the roller body 41 and the main shaft 42, and between the main shaft 42 and the tank body 1, when one of the rotation of the two ends of the main shaft 42 and the rotation between the roller and the main shaft 42 fails, there is still rolling friction between the roller body 41 and the chain 2, so that the maintenance cycle of the roller body 41 can be further extended and its service life can be improved.

[0063] In the coal mine underground coal sludge desilting machine provided by the embodiment of the present invention, the first bearing 44 and the second bearing 45 are both self-lubricating sliding bearings to increase the service life of the pressure roller mechanism 4.

[0064] The coal mine underground coal sludge water desilting machine provided by the embodiment of the present invention is as follows: Figure 7 As shown, it also includes a scraper 5 arranged on the chain 2; the width of the scraper 5 is greater than or equal to 100 mm and less than or equal to 150 mm, and a plurality of water filtering holes 51 are opened on the scraper 5, and the opening rate of the water filtering holes 51 on the scraper 5 is greater than or equal to 60%.

[0065] In this embodiment, in order to solve the problem of large resistance of the scraper 5 when scraping coal slime, the width dimension of the scraper 5 is d, wherein 100mm≤d≤150mm; in this embodiment, by shortening the width of the scraper 5 of the coal slime water cleaning machine in the coal mine, the coal slime settled in the tank body 1 is discharged by the method of "hollowing out", thereby reducing the resistance of the scraper 5 during operation, and avoiding excessive resistance during operation of the scraper 5, which leads to a high failure rate of the coal slime water cleaning machine in the coal mine. Further, in this embodiment, a plurality of water filter holes 51 are also provided on the scraper 5, and the water filter holes 51 are used for dehydrating coal slime to further reduce the resistance of the scraper 5 during operation. It should be noted that since the width of the scraper 5 is greater than or equal to 100mm and less than or equal to 150mm, the width dimension of the tank body 1 may need to be adjusted accordingly to avoid the formation of a "dead zone" in the tank body 1. The opening rate of the scraper 5 is greater than or equal to 60% to reduce the resistance of the scraper 5 during operation, and is conducive to the dehydration of the coal slime, so that the discharged coal slime has lower moisture content. When the coal slime is subsequently transported by a belt, the coal slime will not slip on the belt conveyor.

[0066] In order to improve the strength of the coal scraper 5, the thickness of the scraper 5 is greater than or equal to 18mm. The diameter of the water filter hole 51 is D, where 15mm≤D≤25mm, to prevent excessive coal slime from passing through the water filter hole 51 and causing the scraper 5 to fail, and also to prevent the water filter hole 51 from being blocked. All the water filter holes 51 are divided into multiple rows along the height direction of the scraper 5, each row includes multiple water filter holes 51, and all the water filter holes 51 in each row are arranged at intervals along the width direction of the scraper 5, and the water filter holes 51 in two adjacent rows are arranged in an alternating manner. The scraper 5 is provided with a rib plate 52 to improve the strength of the scraper 5 and avoid damage to the scraper 5 during operation. Among them, the rib plate 52 is arranged on the non-working surface of the scraper 5 to avoid affecting the normal operation of the scraper 5; the scraper 5 has two opposite sides, one side in contact with the coal slime is the working surface of the scraper 5, and the other side is the non-working surface. The rib plate 52 is disposed between two adjacent rows of water filtering holes 51 to prevent the rib plate 52 from affecting the normal function of the scraper 5 of the coal slurry water cleaning machine in the coal mine.

[0067] In this embodiment, if Figure 3As shown, the end of the head section 111 away from the third transition section 12 is provided with a first discharge port 16, and the first discharge port 16 is used to discharge coal slime. The bottom wall of the second horizontal section 13 near the end of the fourth transition section 14 is provided with a second discharge port 17. The coal slime in a slurry state cannot be discharged from the first discharge port 16 due to its strong fluidity. Preferably, in this embodiment, the bottom wall of the second horizontal section 13 near the end of the fourth transition section 14 is provided with a second discharge port 17 for discharging the coal slime in a slurry state. The drive motor drives the chain 2 to drive the scraper 5 to move in the first direction, and the scraper 5 can scrape the large particles of coal slime to the first discharge port 16. When the drive motor drives the chain 2 to drive the scraper 5 to move in the second direction, the scraper 5 can scrape the coal slime in a slurry state to the second discharge port 17, wherein the first direction is opposite to the second direction. The mud tank 18 is connected to the second discharge port 17 and is used to receive the slurry-like coal slime discharged from the second discharge port 17. A mud pump is provided in the mud tank 18. When the slurry-like coal slime in the mud tank 18 accumulates to a certain amount, it can be transported to the filter press for filtering through the mud pump.
