Technical Field

[0001] The utility model relates to the technical field of volatilization kilns, in particular to a refractory masonry structure for a zinc volatilization kiln. Background Art

[0002] The hydrometallurgical zinc smelting process produces leaching residues, which contain a lot of zinc and other valuable metals. In order to improve resource utilization, these leaching residues need to be recycled. At present, the leaching residues are mainly heated at high temperatures in volatilization kilns to volatilize the zinc in the leaching residues to form zinc vapor, which is then converted back into solid zinc through cooling and solidification.

[0003] Since the working temperature of zinc volatilization kiln is usually above 1100℃, the zinc volatilization kiln needs to have strong high temperature resistance. At present, the lining of volatilization kiln is mostly built with mortar and refractory bricks. During the construction, the refractory bricks are not easy to locate, and the stability of the refractory bricks is greatly affected by the construction level. In addition, under long-term high temperature environment, the stability of mortar deteriorates, which easily causes the refractory bricks to fall off, affecting the service life of the lining.

Figure 2 As shown, the sixteen refractory bricks 21 are provided with first plug-in slots 23 on the left and right, and a plug-in block 22 for cooperating with the first plug-in slot 23 is provided between two adjacent refractory bricks 21, and sixteen positioning components for positioning the refractory bricks 21 are provided on the mounting layer 11;

[0030] The plug-in block 22 is composed of a block body 221 and two wing plates 222 respectively arranged on both sides of the block body 221. The cross section of the wing plate 222 is arc-shaped, and the sixteen refractory bricks 21 are provided with a second plug-in groove 24 for matching with the wing plate 222 on one side; Figure 3 As shown, the positioning assembly is a positioning block 12 arranged on the inner wall of the installation layer 11, and the refractory brick 21 is provided with a positioning groove 211 that cooperates with the positioning block 12.

[0031] The masonry process of the above-mentioned masonry structure is as follows: first, pour the installation layer 11 in the volatilization kiln cylinder 1, then apply clay fire mud on the outer wall of the refractory brick 21, align the positioning groove 211 on the refractory brick 21 with the positioning block 12, and install the refractory brick 21 on the installation layer 11. After all the refractory bricks 21 are installed, the plug-in block 22 is inserted into the first plug-in groove 23. After the masonry is completed, the refractory brick 21 will be limited by the plug-in block 22, and the refractory brick 21 cannot move at will, thereby improving stability.

[0032] Example 2: Figure 4 As shown, this embodiment is substantially the same as the first embodiment, except that the cross-sections of the second insertion slot 24 and the wing plate 222 are both dovetail-shaped, so that the wing plate 222 can be inserted into the second insertion slot 24 .

[0033] Example 3: Figure 5 As shown, this embodiment is basically the same as the embodiment 1, except that four clamping columns 25 are vertically slidably arranged in the wing plate 222, and the sliding directions of two adjacent clamping columns 25 are opposite, and the inner wall of the second plug-in slot 24 is provided with clamping holes for slidingly engaging with the clamping columns 25 in a one-to-one correspondence, and a driving member for controlling the clamping columns 25 to slide up and down is arranged in the wing plate 222;

The clamping column 25 is provided with an oblique groove for cooperating with the fixed block 27 for horizontal sliding connection, and the inclination directions of two adjacent fixed blocks 27 are opposite. Four semicircular grooves are arranged on the side wall of the slide bar 26, and the fixed blocks 27 are arranged in the semicircular grooves one by one.

[0035] The working principle of the above-mentioned driving member is: after the plug-in block 22 is inserted into the first plug-in slot 23, by pressing the slide bar 26, the slide bar 26 slides to the left, and when the fixed block 27 slides to the left following the slide bar 26, under the cooperation of the fixed block 27 and the inclined slide slot, the card column 25 will slide out and engage with the card hole.

[0036] Embodiment 4: This embodiment is basically the same as Embodiment 3, except that the driving member is an airbag disposed in the wing plate 222 .

[0037] The working principle of the above-mentioned driving member is: the airbag is inflated through the inflation mechanism to make the clamping column 25 slide out.

[0038] Example 5: Figure 7As shown, this embodiment is basically the same as the embodiment 1, except that a latch 28 is provided on the refractory brick 21 for transverse sliding, and a socket for mating with the latch 28 is provided on the positioning block 12.

[0039] The working principle of the above-mentioned latch 28 is: after the positioning groove 211 on the refractory brick 21 is aligned with the positioning block 12, the latch 28 is inserted, and the latch 28 will be inserted into the insertion hole, so that the refractory brick 21 is fixed by the latch 28, and the refractory brick 21 will not fall off even if the clay fire mud fails.
