Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of titanium dioxide production equipment and relates to a crusher and a powder receiving device thereof. Background Art
[0002] Titanium dioxide is an important inorganic chemical pigment, the main component of which is titanium dioxide. There are two production processes for titanium dioxide: the sulfuric acid process and the chlorination process. It has important uses in industries such as coatings, inks, papermaking, plastics and rubber, chemical fibers, and ceramics.
[0003] When titanium dioxide is processed, the raw materials need to be crushed. Figure 1 As shown, the secondary crushing and powder receiving device of the original titanium dioxide dedicated to chemical fiber masterbatch is a square elbow, the crushing host (11) is in a negative pressure state, and the material is drawn into the crushing host (11) through the square elbow (22) by negative pressure.

[0005] Serial number Temperature / ℃ L value b-value Water dispersibility 1 80 99.5 -0.91 98 2 85 99.4 -0.97 98.1 3 84 99.3 -0.95 97.9 4 82 99.2 -0.93 98.1 5 85 99.6 -0.94 98 6 86 99.5 -0.95 97.9 7 87 99.4 -0.94 98.2 8 88 99.2 -0.90 98.1 9 84 99.5 -0.91 98.3 10 83 99.4 -0.90 98.1 average value 84.4 99.4 -0.93 98.07
[0006] Since the material flow cannot be controlled, a large amount of high-temperature titanium dioxide enters the square elbow (22), the material is blocked in the square elbow (22), and the high temperature causes poor material performance.
[0007] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. Utility Model Content

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0026] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention. Example
[0027] A crusher, such as Figure 2 As shown, it includes a crushing host 3, and a motor 1 for driving the crushing host 3 is arranged on the outside of the crushing host 3, and the motor 1 and the crushing host 3 are connected through a V-belt 2; the motor 1 and the crushing host 3 are both arranged on a base 5, and a discharge bin 6 is arranged at the discharge port of the crushing host 3, and the powder receiving port of the crushing host 3 is connected to the square elbow 4 through a pipe joint 7.
[0028] In order to solve the problem that a large amount of high-temperature titanium dioxide enters the square elbow due to the inability to control the flow of the material, causing the material performance to deteriorate, this embodiment has made the following improvements on the basis of the above:
[0029] A side opening is provided on the side wall of the square elbow 4, and a limit plate 8 for controlling the air flow is provided at the side opening. The limit plate 8 can adjust the upper and lower positions to block part or all of the side opening, thereby adjusting the air flow of the external air entering the square elbow 4, effectively cooling the material entering, and significantly improving the output and material performance.
[0030] Specifically, the upward and downward adjustment of the limit plate 8 in this embodiment adopts the following structure: a mounting frame is provided at the square corner elbow 4 above the side opening, and the limit plate 8 is fixed to the mounting frame by bolts, so as to achieve the blocking of the side opening. When in use, the position of the limit plate 8 is adjusted first, and then fixed to the mounting frame by bolts after being adjusted into place.
[0031] Preferably, slide groove components for guiding the displacement of the limiting plate are arranged on both sides of the side opening, and the slide groove components include frames arranged on both sides of the side opening, and there is a gap between the inner side of the frame and the square corner elbow for the limiting plate to be inserted.
[0032] By modifying the crusher's powder receiving device (square elbow), additional external air can flow into the square elbow to cool the material, greatly alleviating the impact of high temperature on material performance caused by a large amount of high-temperature titanium dioxide entering the square elbow. At the same time, the air flow entering the square elbow is adjusted by the limit plate to meet the production needs of products of different specifications.
[0033] The results of material performance analysis after transformation are shown in Table 2:
[0034] Serial number Temperature / ℃ L value b-value Water dispersibility 1 64 100.1 -1.09 98.5 2 61 100.3 -1.03 99.0 3 63 100.5 -1.05 98.9 4 62 100.2 -1.11 99.2 5 63 100.3 -1.08 98.5 6 59 100.4 -1.07 99.1 7 64 100.1 -1.11 99.1 8 62 100.5 -1.09 98.9 9 59 100.2 -1.03 99.1 10 60 100.3 -1.04 98.8 average value 61.7 100.29 -1.07 98.91
[0035] Table 2: Material performance analysis after transformation
[0036] The difference in material performance before and after the transformation is shown in Table 3:
[0037] Temperature / ℃ L value b-value Water dispersibility Mean before transformation 84.4 99.4 -0.93 98.07 Mean after transformation 61.7 100.29 -1.07 98.91 Difference 22.7 -0.89 0.14 -0.84
[0038] Table 3: Differences in material properties before and after transformation
[0039] After the transformation, the material blockage was significantly reduced, the material performance was significantly improved, the temperature dropped by an average of 22.7°C, the L value increased by 0.89, the b value decreased by 0.14, and the water dispersibility increased by 0.84.
[0040] The number of manual cleaning of clogged powder has been reduced, the crusher is used more smoothly, and the output has been significantly improved from 1.0t per hour to 1.9t per hour.
