Description

Technical Field

[0001] This utility model relates to the field of coal slime filtration technology, specifically to a coal slime filtration and recycling device. Background Technology

[0002] Horizontal drive, high centrifugal force centrifuges are commonly used equipment for dewatering coal slime or other materials in coal mines. When the coal slime or material to be dewatered enters the scraper cone through the feed inlet, it is evenly distributed into the space between the scraper and the screen basket due to the high centrifugal force. Utilizing the inclination angle of the screen basket and the speed difference between the screen basket and the scraper, the coal slime cake formed on the screen basket moves continuously from the small end to the large end of the screen basket and is discharged. However, the original gap between the screen basket and the scraper is a fixed gap, which is easily affected by the particle size and flow rate of the coal slime, causing the scraper and screen basket to seize up and the scraper to wear severely. A Chinese patent discloses a coal slime filtration and recycling device (authorization announcement number CN213669879U). This patent technology includes a scraper and a screen basket located inside a centrifugal dewatering machine. The small-diameter end of the scraper or the small-diameter end of the screen basket is detachably connected to a spacing adjustment device to adjust the distance between the small-diameter ends of the scraper and the screen basket. This invention increases the vertical gap between the scraper and the screen basket by adjusting the spacing, preventing the scraper from seizing up and reducing scraper wear. The coal slime recovery bin prevents coal slime cake from entering the air. A filter further prevents coal slime cake from entering the air. A waterproof cover prevents rainwater from entering the coal powder recovery channel. This patented technology solves the problems of blockage caused by excessive coal slime discharge and the direct release of some coal slime cake into the air under wind pressure.

[0003] However, in the existing technology, coal slime is prone to clogging the filter holes of the filter disc during filtration, which reduces the efficiency of coal slime filtration. It is necessary to solve the problem of cleaning the filter holes of the filter disc at the same time as filtering coal slime in the existing technology.

[0004] Therefore, those skilled in the art have provided a coal slime filtration and recycling device to solve the problems mentioned in the background art. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides:

[0006] A coal slime filtration and recycling device includes: a filter barrel, the top of which is sealed and fixed with a top cover, and a filter disc for filtering coal slime is installed inside the filter barrel; a stirring structure for cleaning coal slime clogging the filter holes of the filter disc is installed inside the filter barrel; the stirring structure includes a servo motor fixedly installed on the top cover, the output end of the servo motor rotating through the inner wall of the top cover and fixedly connected to a stirring rod, and a transmission rod rotatably mounted at the bottom end of the stirring rod at the center of the filter disc; a load-bearing bracket is fixedly provided on the outer wall of the transmission rod, and a plurality of anti-clogging cones for cleaning coal slime in the filter holes of the filter disc are movably provided on the surface of the load-bearing bracket.

[0007] Preferably, a load-bearing frame is fixedly mounted on the outer wall of the filter barrel, and three support frames are fixedly mounted in a ring at equal intervals at the bottom of the load-bearing frame.

[0008] Preferably, the load-bearing frame is equipped with a controller for controlling the stirring structure.

[0009] Preferably, the surface of the load-bearing bracket is provided with several vertical sliding rods at equal intervals, and anti-blocking cones are slidably sleeved on the outer side of the vertical sliding rods.

[0010] Preferably, the anti-blocking cone has a movable disc that is fixedly mounted on a vertical slide rod and is slidably disposed inside it.

[0011] Preferably, a tension spring is installed between the movable disc and the anti-blocking cone.

[0012] Preferably, the outer wall of the stirring rod is provided with three stirring scrapers in a ring shape, and the inner edge of the stirring scraper is provided with a stirring shaft, and the outer wall of the stirring shaft is provided with a stirring ring frame.

[0013] The top cover is provided with a feed hopper, and the bottom of the filter barrel is sealed with a discharge hopper.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] In this invention, during coal slime filtration and recycling, the coal slime is placed into the filter barrel through the feed hopper and positioned on the filter disc. The servo motor of the stirring structure is activated, driving the stirring rod and its transmission rod to rotate. The rotating stirring rod causes the stirring scraper to rotate along the filter disc inside the filter barrel, allowing the coal slime on the filter disc to be discharged through the filter holes into the discharge hopper. The transmission rod continues to rotate, causing the load-bearing bracket to move circumferentially along the filter disc, preventing the anti-clogging cone from squeezing the filter holes and discharging the blocked coal slime. The bracket then resets under the action of a spring. Real-time cleaning of the filter holes on the filter disc reduces the likelihood of coal slime clogging the filter disc and thus decreasing the efficiency of coal slime filtration.

The output end of the servo motor 901 rotates through the inner wall of the top cover 2 and is fixedly connected to a stirring rod 902. The bottom end of the stirring rod 902 is fixedly fitted with a transmission rod 904 rotatably set at the center of the filter disc 7. A load-bearing bracket 905 is fixedly provided on the outer wall of the transmission rod 904, and a plurality of anti-clogging cones 908 for cleaning coal slime in the filter holes of the filter disc 7 are movably provided on the surface of the load-bearing bracket 905.

[0027] A load-bearing frame 3 is fixedly mounted on the outer wall of the filter tank 1, and three support frames 4 are fixedly mounted in a ring at equal intervals at the bottom of the load-bearing frame 3. A controller 5 for controlling the stirring structure 9 is installed on the load-bearing frame 3. Several vertical sliding rods 906 are fixedly mounted at equal intervals on the surface of the load-bearing bracket 905, and anti-clogging cones 908 are slidably sleeved on the outer side of the vertical sliding rods 906.

[0028] The anti-clogging cone 908 has a movable disc 907 slidably mounted inside, which is fixedly mounted on a vertical slide rod 906. A tension spring 909 is installed between the movable disc 907 and the anti-clogging cone 908.

[0029] The top cover 2 has a through feed hopper 8, and the bottom of the filter barrel 1 is sealed with a discharge hopper 6.

[0030] According to the above embodiments, the working principle of this invention is as follows:

[0031] When filtering and recycling coal slime, the coal slime is placed into the filter barrel 1 through the feed hopper 8 and placed on the filter plate 7.

[0032] After the servo motor 901 of the stirring structure 9 is started, the servo motor 901 drives the stirring rod 902 and its transmission rod 904 to rotate.

[0033] The continuously rotating transmission rod 904 can drive the load-bearing bracket 905 to rotate in a ring along the filter plate 7, which can cause the anti-clogging cone 908 on the load-bearing bracket 905 to squeeze the filter hole of the filter plate 7 along the vertical slide rod 906, and discharge the coal sludge that is stuck inside. The anti-clogging cone 908 can be reset and retracted by the elastic force of the tension spring 909.

[0034] The filter holes of filter disc 7 are cleaned in real time to reduce the clogging of filter disc 7 by coal sludge, which would reduce the efficiency of coal sludge filtration.
