[0016] The beneficial effects of this utility model are:
[0017] This utility model provides a scraper for a coal slurry cleaning machine in an underground coal mine. The underground coal slurry cleaning machine includes a motor, a trough, and a transmission assembly. The scraper of the underground coal slurry cleaning machine is disposed in the trough. The motor is connected to the scraper of the underground coal slurry cleaning machine through the transmission assembly, and drives the scraper of the underground coal slurry cleaning machine to move in the trough, so as to scrape the coal slurry in the trough to the discharge port of the trough.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] like Figure 1 As shown, one embodiment of this utility model provides a scraper 1 for a coal slurry cleaning machine in an underground coal mine. The coal slurry cleaning machine includes a motor, a trough, and a transmission assembly. The scraper 1 is disposed in the trough. The motor is connected to the scraper 1 through the transmission assembly and drives the scraper 1 to move within the trough, scraping the coal slurry in the trough to the discharge port of the trough. The width of the scraper 1 is greater than or equal to 100 mm and less than or equal to 150 mm. The scraper 1 has several filter holes 11.
[0024] This embodiment provides a scraper 1 for an underground coal slurry cleaning machine, applied to an underground coal slurry cleaning machine. The underground coal slurry cleaning machine includes a trough, a motor, and a transmission assembly. Coal slurry enters the trough from one end, and coal slurry exits from the other end. The motor is mounted on the trough and is connected to the scraper 1 of the underground coal slurry cleaning machine via the transmission assembly, which is typically a chain. The scraper 1 slides within the trough via a slide rail. The motor drives the scraper 1 to move within the trough, scraping the coal slurry to the discharge port. Optionally, in this embodiment, multiple scrapers 1 of the underground coal slurry cleaning machine are spaced apart within the trough, and all scrapers 1 are connected to the transmission assembly.
[0025] In this embodiment, to address the issue of high resistance in the scraper 1 of the underground coal slurry cleaning machine when scraping coal slurry, the width of the scraper 1 is d, where 100mm ≤ d ≤ 150mm. By shortening the width of the scraper 1, the settled coal slurry in the tank is discharged through a "hollowing" method, thereby reducing the resistance of the scraper 1 during operation and preventing a high failure rate due to excessive resistance. Furthermore, in this embodiment, the scraper 1 is also provided with several filter holes 11 for coal slurry dewatering, further reducing the resistance during operation. It should be noted that since the width of the scraper 1 of the coal slurry cleaning machine in the coal mine is greater than or equal to 100mm and less than or equal to 150mm, the width of the trough of the coal slurry cleaning machine in the coal mine needs to be adjusted accordingly to avoid the formation of a "dead zone" in the trough.
[0026] This embodiment provides a scraper 1 for an underground coal slurry cleaning machine. By controlling the width of the scraper 1 and opening filter holes 11 on the scraper 1, the resistance during operation is reduced, and dewatering is facilitated, resulting in lower moisture content in the discharged coal slurry, which is beneficial for subsequent transportation. Compared with the prior art, the failure rate of the underground coal slurry cleaning machine is significantly reduced.
[0027] In this embodiment, the scraper 1 of the underground coal slurry cleaning machine is connected to the transmission assembly at both ends, and is also slidably connected to the slide rail in the trough. This is conventional technology in the field, so it will not be described in detail here.
[0028] The scraper 1 of the coal slurry cleaning machine in the underground coal mine provided in this embodiment of the utility model is as follows: Figure 1As shown, the thickness of the scraper 1 of the underground coal slurry cleaning machine is greater than or equal to 18mm.
[0029] In this embodiment, in order to improve the strength of the scraper 1 of the coal slurry cleaning machine in the underground coal mine, the thickness of the scraper 1 of the coal slurry cleaning machine in the underground coal mine is greater than or equal to 18mm.
[0030] It should be noted that the width dimension of the scraper 1 of the underground coal slurry cleaning machine mentioned above refers to the width direction dimension of the scraper 1, and the thickness dimension of the scraper 1 refers to the thickness direction dimension of the scraper 1. The width direction of the scraper 1 of the underground coal slurry cleaning machine is already specified. Figure 1 The standard specifies that the thickness direction of the scraper 1 of the coal slurry cleaning machine in the underground coal mine is... Figure 1 The direction perpendicular to the paper.
[0031] The scraper 1 of the coal slurry cleaning machine in the underground coal mine provided in this embodiment of the utility model is as follows: Figure 1 As shown, the diameter of the filter hole 11 is greater than or equal to 15 mm and less than or equal to 25 mm.
[0032] In this embodiment, the diameter of the filter hole 11 is D, wherein 15mm≤D≤25mm, so as to avoid excessive coal slurry passing through the filter hole 11 and causing the scraper 1 of the coal slurry water cleaning machine in the coal mine to malfunction, and also to prevent the filter hole 11 from becoming clogged.
[0033] The scraper 1 of the coal slurry cleaning machine in the underground coal mine provided in this embodiment of the utility model is as follows: Figure 1 As shown, the opening rate of the filter holes 11 on the scraper 1 of the underground coal slurry cleaning machine is greater than or equal to 60%.
[0034] In this embodiment, the scraper 1 of the coal slurry cleaning machine in the underground coal mine has an opening rate of 60% or greater, so as to reduce the resistance of the scraper 1 during operation and facilitate coal slurry dewatering, resulting in lower moisture content in the discharged coal slurry. This prevents the coal slurry from slipping on the conveyor belt when it is subsequently transported by belt.
[0035] It should be noted that the opening rate of the filter holes 11 on the scraper 1 of the underground coal slurry cleaning machine is the ratio of the total area of the filter holes 11 on the scraper 1 of the underground coal slurry cleaning machine to the area of the scraper 1 of the underground coal slurry cleaning machine.
[0036] The scraper 1 of the coal slurry cleaning machine in the underground coal mine provided in this embodiment of the utility model is as follows: Figure 1As shown, all the filter holes 11 are divided into multiple rows along the height direction of the scraper 1 of the coal slurry cleaning machine in the underground coal mine. Each row includes multiple filter holes 11, and all the filter holes 11 in each row are spaced apart along the width direction of the scraper 1 of the coal slurry cleaning machine in the underground coal mine. The filter holes 11 in adjacent rows are staggered.
[0037] In this embodiment, by limiting the distribution of the filter holes 11, the filtration effect of the filter holes 11 can be improved, which is beneficial to the dewatering of coal slime, resulting in lower moisture content in the discharged coal slime. When the coal slime is subsequently transported by belt conveyor, the coal slime will not slip on the belt conveyor.
[0038] The scraper 1 of the coal slurry cleaning machine in the underground coal mine provided in this embodiment of the utility model is as follows: Figure 1 As shown, it also includes a stiffening plate 12, which is disposed on the non-working surface of the scraper 1 of the underground coal slurry cleaning machine in the coal mine, and the stiffening plate 12 extends along the width direction of the scraper 1 of the underground coal slurry cleaning machine in the coal mine.
[0039] In this embodiment, the scraper 1 of the underground coal slurry cleaning machine is equipped with reinforcing ribs 12 to improve the strength of the scraper 1 and prevent damage during operation. Specifically, in this embodiment, the reinforcing ribs 12 are located on the non-working surface of the scraper 1 to avoid affecting its normal operation. The scraper 1 has two opposing sides; the side in contact with the coal slurry is the working surface, and the other side is the non-working surface.
[0040] The scraper 1 of the coal slurry cleaning machine in the underground coal mine provided in this embodiment of the utility model is as follows: Figure 1 As shown, the stiffener 12 is located between two adjacent rows of filter holes 11.
[0041] In this embodiment, the stiffener 12 is disposed between two adjacent rows of filter holes 11 to avoid the stiffener 12 affecting the normal function of the scraper 1 of the coal slurry cleaning machine in the coal mine.
[0042] The scraper 1 of the coal slurry cleaning machine in the underground coal mine provided in this embodiment of the utility model is as follows: Figure 1 As shown, the width of the stiffener 12 is greater than or equal to 60 mm, and the thickness is greater than or equal to 10 mm.
[0043] Preferably, in this embodiment, the width of the stiffening plate 12 is greater than or equal to 60mm, and the width of the stiffening plate 12 must be less than or equal to the width of the scraper 1 of the coal slurry cleaning machine in the underground coal mine; the thickness of the stiffening plate 12 is greater than or equal to 10mm; the width of the stiffening plate 12 is the dimension in the width direction, which is the same as the width direction of the scraper 1 of the coal slurry cleaning machine in the underground coal mine; the thickness of the stiffening plate 12 is the dimension in the thickness direction, which is the height direction of the scraper 1 of the coal slurry cleaning machine in the underground coal mine. Figure 1 As shown in the image.
[0044] Preferably, in this embodiment, the scraper 1 of the underground coal slurry cleaning machine is further provided with ribs on its non-working surface. The ribs extend along the height direction of the scraper 1 of the underground coal slurry cleaning machine and are located between two adjacent filter holes 11 to further improve the strength of the scraper 1 of the underground coal slurry cleaning machine. At the same time, the two ends of the ribs can also be connected to two adjacent stiffening plates 12.
[0045] The scraper 1 of the coal slurry cleaning machine in the underground coal mine provided in this embodiment of the utility model is as follows: Figure 1 As shown, the scraper 1 of the underground coal slurry cleaning machine in the coal mine is provided with a wear-resistant layer at its lower end.
[0046] Preferably, in this embodiment, a wear-resistant layer is provided at the lower end of the scraper 1 of the underground coal slurry cleaning machine to improve the service life of the scraper 1 of the underground coal slurry cleaning machine. The wear-resistant layer can be a carburized layer or a wear-resistant layer can be provided on the surface of the scraper 1 of the underground coal slurry cleaning machine.
