Description

Technical Field

[0001] This utility model relates to the field of refractory brick technology, and in particular to a special irregularly shaped composite refractory brick for rotary kilns. Background Technology

[0002] Rotary kilns, also known as rotary kilns, are widely used in many industrial fields and play an important role in production. They are core equipment in industries such as cement, metallurgy, chemicals, and lime.

[0003] The existing rotary kiln linings generally use refractory bricks with trapezoidal or fan-shaped cross sections, which are laid in a ring or staggered pattern along the inner wall of the kiln.

[0004] A rotary kiln is a rotating body that is constantly rotating and heated at high temperatures during production. The kiln body is generally composed of refractory bricks, castables, and a specially made kiln lining made of steel plates.

[0005] The existing method of constructing rotary kilns involves stacking ordinary refractory bricks and cement, especially rectangular refractory bricks. When rectangular refractory bricks are stacked into a cylindrical shape, steel plates and other reinforcement devices need to be installed on top. The original stacking method relies heavily on skilled workers, and the stacking and installation of reinforcement devices are also quite troublesome. In order to stack refractory bricks more conveniently while also taking into account the insulation effect of the rotary kiln, a special irregularly shaped composite refractory brick for rotary kilns is designed. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a special irregularly shaped composite refractory brick for rotary kilns.

[0007] This utility model provides a special irregularly shaped combined refractory brick for rotary kilns, comprising: an arc-shaped refractory brick, wherein the arc-shaped refractory brick includes a first arc-shaped brick and a second arc-shaped brick fixedly installed on the first arc-shaped brick, the first arc-shaped brick being on the inner side and the second arc-shaped brick being on the outer side, the first arc-shaped brick having a gas passage for gas to pass through, and the second arc-shaped brick having a steel plate passage for installing an outer steel plate.

[0008] Preferably, the first arc-shaped brick has a first perforation running from top to bottom, the first perforation being a gas channel, and the first arc-shaped brick has an installation hole communicating with the first perforation, and the number of installation holes is at least one.

[0009] Preferably, the second arc-shaped brick has a second perforation running from top to bottom, and the second perforation is a steel plate channel.

[0010] Preferably, the first arc-shaped brick and the second arc-shaped brick are arranged in a staggered manner, and the protruding part of the lower arc-shaped refractory brick can be stuck in the concave part of the upper arc-shaped refractory brick.

[0011] Preferably, the first arc-shaped brick and the second arc-shaped brick are arranged in a staggered manner, and the protruding part of the arc-shaped refractory brick on the left can be stuck in the concave part of the arc-shaped refractory brick on the right.

[0012] Compared with related technologies, the special irregular-shaped composite refractory brick for rotary kilns provided by this utility model has the following beneficial effects: This device has a simple structure and is relatively easy to manufacture. Different arc-shaped refractory bricks can be designed using rotary kilns of different sizes, and the quantity and size can be adjusted. Multiple arc-shaped refractory bricks can be installed with a small amount of cement. Because the arc-shaped refractory bricks are arranged in a staggered manner both vertically and horizontally, the installation is relatively easy and secure.

[0013] The design of the first and second curved bricks can effectively provide insulation, and the double-layer insulation design can effectively isolate the temperature.

[0014] The gas passage can be connected to the mounting hole of the rotary kiln, thus providing an additional channel for smoke exhaust. Alternatively, the gas passage can be used for gas filling, where external air is pumped into the rotary kiln through the mounting hole, allowing more oxygen to be introduced into the kiln, which is beneficial for combustion. Similarly, the gas passage can also be used to inject extinguishing agents into the rotary kiln, making it very important.

[0015] Steel plates can be installed inside the steel plate channel, which can provide secondary reinforcement to the entire arc-shaped refractory brick, thereby improving the overall strength of the rotary kiln. This also allows the steel plates to be installed inside the refractory brick, making the kiln more aesthetically pleasing. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] Please see Figures 1 to 4 This utility model provides a special irregularly shaped combined refractory brick for rotary kilns, comprising: an arc-shaped refractory brick, the arc-shaped refractory brick including a first arc-shaped brick 2 and a second arc-shaped brick 1 fixedly installed on the first arc-shaped brick 2, the first arc-shaped brick 2 being on the inner side and the second arc-shaped brick 1 being on the outer side, the first arc-shaped brick 2 being provided with a gas passage 4 for gas to pass through, and the second arc-shaped brick 1 being provided with a steel plate passage 3 for installing an outer steel plate.

[0021] In this embodiment, the device has a simple structure and is relatively easy to manufacture. Different arc-shaped refractory bricks can be designed using rotary kilns of different sizes, and the quantity and size can be adjusted. Multiple arc-shaped refractory bricks can be installed with a small amount of cement. Because the arc-shaped refractory bricks are arranged in a staggered manner both vertically and horizontally, the installation is relatively easy and secure. The design of the first arc-shaped brick 2 and the second arc-shaped brick 1 can effectively provide heat insulation. The double-layer heat insulation design can effectively isolate the temperature.

[0022] For example, if a larger rotary kiln is designed, then arc-shaped refractory bricks with a smaller curvature can be produced, which allows for the stacking of larger rotary kilns. If the rotary kiln is designed to be relatively small, then it is sufficient to produce refractory bricks with a larger curvature.

[0023] The first arc-shaped brick 2 has a first perforation from top to bottom, which is a gas channel 4. The first arc-shaped brick 2 also has an installation hole 5, which is connected to the first perforation. There is at least one installation hole 5.

[0024] In this embodiment, the gas channel 4 can be connected to the mounting hole 5 of the rotary kiln, thus providing an additional channel for smoke exhaust. Alternatively, the gas channel 4 can be used for gas filling, with external air being pumped into the rotary kiln through the mounting hole 5. This allows for the injection of more oxygen into the rotary kiln, which is beneficial for combustion. Similarly, the gas channel 4 can also be used to inject extinguishing agents into the rotary kiln. Therefore, the gas channel 4 is very important.

[0025] Alternatively, it can be designed so that not every first arc brick 2 has a mounting hole 5, but only some of the first arc bricks 2 are designed to have mounting holes 5. The first arc bricks 2 with mounting holes 5 are arranged in the entire sequence, and the first arc bricks 2 without mounting holes 5 are arranged in the entire sequence. In this way, different rotary kilns can be designed according to different needs.

[0026] The second arc-shaped brick 1 has a second perforation from top to bottom, which is a steel plate channel 3.

[0027] In this embodiment, a steel plate can be installed inside the steel plate channel 3, which can provide secondary reinforcement to the entire arc-shaped refractory brick and improve the overall strength of the rotary kiln. This allows the steel plate to be installed inside the refractory brick, making it more aesthetically pleasing.

[0028] The first arc-shaped brick 2 and the second arc-shaped brick 1 are arranged in a staggered manner, and the protruding part of the lower arc-shaped refractory brick can be stuck in the concave part of the upper arc-shaped refractory brick.

[0029] In this embodiment, the curved refractory bricks can be installed by splicing them together vertically to form a rotary kiln. This way, a small amount of cement can be used to bond the upper and lower parts together.

[0030] The first arc-shaped brick 2 and the second arc-shaped brick 1 are arranged in a staggered manner, and the protruding part of the arc-shaped refractory brick on the left can be stuck in the concave part of the arc-shaped refractory brick on the right.

[0031] This embodiment is similar to the staggered arrangement, allowing for left-right splicing, with a small amount of cement used to bond the joints together.

[0032] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
