[0048] According to a slag removal device 100 of the present invention, Figure 1 As shown, including:
[0049] a transport pipeline 110 configured to transport cement dust;
[0050] The sedimentation tank 120 is provided at the lower end of the transport pipe 110. The upper end of the sedimentation tank 120 is provided with a feed end, and the feed end is connected to the transport pipe 110.
[0051] The filtering mechanism 130 is disposed in the transport pipe 110 and located above the feed end, and is configured to block the slag in the cement ash in the transport pipe 110 .
[0052] The cement ash flows along the extension direction Z of the transport pipe 110. When it flows to the filtering mechanism 130, the residue in the cement ash will hit the filtering device and enter the sedimentation box 120 through the feed end under the action of gravity for deposition. The cement ash will not pass through the filtering mechanism 130 and continue to flow along the transport pipe 110 to the designated location. The slag removal device 100 can remove the residue in the cement ash during transportation, greatly improving the cement production efficiency. In addition, the slag removal device 100 has a simple structure and a good slag removal effect.
[0053] In one example of the present invention, it further includes: a pneumatic mechanism 140,
[0054] It is in communication with the settling tank 120 and is configured to blow gas into the settling tank 120 to drive the cement ash in the transport pipeline 110 to flow;
[0055] That is to say, the pneumatic mechanism 140 blows gas into the sedimentation box 120, and the gas enters the transport pipe 110 through the feed end of the sedimentation box 120. The gas drives the cement ash in the transport pipe 110 to flow along the extension direction Z of the transport pipe 110, thereby realizing the driving of the cement ash. Its main function is to assist the cement ash to flow in the transport pipe 110.
[0056] It is worth noting that the upward blowing force generated by the gas blown into the sedimentation box 120 by the pneumatic mechanism 140 on the cement dust is not sufficient to blow the cement dust falling into the sedimentation box 120 from the sedimentation box 120 to the transportation pipeline 110; in short, the blowing force of the pneumatic mechanism 140 is less than the gravity of the cement dust.
[0057] In one example of the present invention, the pneumatic mechanism 140 includes:
[0058] a blower 141 configured to pressurize external gas to generate a driving gas having a positive pressure;
[0059] A blast pipe 142, one end of which is connected to the blower 141, and the other end of which is connected to the sedimentation tank 120;
[0060] That is to say, the blower 141 pressurizes the external gas to generate a driving gas with positive pressure. The driving gas enters the sedimentation box 120 through the blower pipe 142, and the gas enters the transport pipe 110 through the feed end of the sedimentation box 120. The gas drives the cement ash in the transport pipe 110 to flow along the extension direction Z of the transport pipe 110, thereby realizing the driving of the cement ash.
[0061] In one example of the present invention, the transport pipe 110 has a first end side 111 and a second end side 112, the height of the first end side 111 is higher than the height of the second end side 112, and the pneumatic mechanism 140 is configured to drive the cement ash to flow from the first end side 111 toward the second end side 112.
[0062] By setting the height of the first end side 111 higher than the height of the second end side 112, the entire transport pipe 110 can be tilted, allowing the cement ash to flow automatically under the action of gravity in the transport pipe 110, reducing the movement resistance of the cement ash.
[0063] In one example of the present invention, Figure 2 As shown, the filtering mechanism 130 includes:
[0064] a filter curtain 131 comprising a plurality of curtain strips 1311 extending along the longitudinal direction Y of the transport pipe 110 and spaced apart in the transverse direction X, the filter curtain 131 covering the cross section of the transport pipe 110;
[0065] In other words, the curtain strips 1311 are strip-shaped, with gaps between each strip 1311. The maximum gap between two adjacent strips 1311 is smaller than the outer diameter of the debris, thereby preventing the debris from flowing through the gap between two adjacent strips 1311. The curtain strips 1311 include a threading line and a plurality of beads sequentially threaded onto the threading line, with the beads sequentially arranged at intervals along the extension direction of the threading line. Preferably, the beads of two adjacent strips 1311 are staggered, which further reduces the gap between the two adjacent strips 1311 and improves the rejection rate of filtered debris.
[0066] Preferably, to facilitate connection of the filter curtain 131, a connecting plate may be provided at the upper end of the filter curtain 131, thereby facilitating connection between the plurality of curtain bars 1311 on each filter curtain 131 and the transport pipe 110. For example, the filter curtain 131 may be connected by fasteners or pre-set hooks.
[0067] The filter curtain 131 can be provided to block cement dust passing through the transport pipeline 110. The slag will collide with the filter curtain 131 and be fed into the sedimentation tank 120 through the feed end under the action of gravity. Covering the cross-section of the transport pipeline 110 with the filter curtain 131 can more effectively block and filter the cement dust in the transport pipeline 110.
[0068] In one example of the present invention, the filter curtains 131 include a plurality of filter curtains 131, which are spaced apart along the extension direction Z of the transport pipe 110; wherein the span of the plurality of filter curtains 131 in the extension direction Z of the transport pipe 110 is smaller than the span of the feed end;
[0069] That is, by providing multiple filter curtains 131, the cement ash flowing through the transport pipeline 110 can be filtered multiple times, thereby greatly improving the success rate of the filter curtains 131 in blocking the debris in the cement ash. Moreover, the span of the multiple filter curtains 131 in the extension direction Z of the transport pipeline 110 is smaller than the span of the feed end, so that the filtered debris can fall into the sedimentation tank 120.
[0070] In one example of the present invention, the filter curtain 131 forms an acute angle with the extension direction Z of the transport pipeline 110 ;
[0071] That is, the filter curtain 131 is placed at an inclined angle, thereby increasing the contact area between the filter curtain 131 and the cement dust in the transportation pipeline 110 , and improving the success rate of the filter curtain 131 in filtering the residue.
[0072] In one example of the present invention, the sedimentation box 120 is further provided with a slag discharge port 121 , and a slag discharge door 122 is detachably mounted on the slag discharge port 121 ;
[0073] By setting the slag discharge port 121, it is convenient to clean out the slag from the sedimentation box 120 after the slag accumulates to a certain mass in the sedimentation box 120, and the slag discharge door 122 can seal the slag discharge port 121, thereby preventing the slag from being discharged from the slag discharge port 121 during the operation of the slag removal device 100.
[0074] In one example of the present invention, the slag discharge door 122 is provided near the lower end side of the sedimentation box 120 ; by being provided at the lower end of the sedimentation box 120 , it is convenient to remove slag from the sedimentation box 120 .
[0075] In one example of the present invention, a mounting plate 123 is provided on the slag discharge door 122 , and the mounting plate 123 is connected to the sedimentation box 120 via a fastener 124 ;
[0076] For example, a plurality of first mounting holes are provided on the mounting plate 123, and a plurality of second mounting holes are provided on the sedimentation box 120. The first mounting holes correspond to the second mounting holes one by one, and the fasteners 124 are passed through the first mounting holes and the second mounting holes in sequence. By providing the fasteners 124, the slag discharge door 122 can be conveniently disassembled and assembled at the slag discharge port 121, which is reliable and convenient.
[0077] In one example of the present invention, a sealing ring is provided between the slag discharge port 121 and the slag discharge door 122 . The provision of the sealing ring can improve the sealing between the slag discharge port 121 and the slag discharge door 122 and prevent slag from being discharged during the operation of the slag removal device 100 .
[0078] The exemplary implementation of the slag removal device 100 proposed in the present invention is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present invention, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present invention can be combined in various ways without exceeding the scope of protection of the present invention, which is determined by the appended claims.
