[0018] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0019] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] like Figs. 1-3As shown in the figure, the present invention provides a heat-insulating composite precast block for a lime rotary kiln, including a heat-insulating composite precast block body 1, and further including: a slot 2 horizontally formed on the top of the front side of the heat-insulating composite precast block body 1, and a locking strip 3 integrally formed on the back side of the heat-insulating composite precast block body 1 for use with the slot 2. By setting the slot 2 and the locking strip 3, two sets of heat-insulating composite precast block bodies 1 can be quickly locked together, improving the tightness of the connection. Multiple sets of heat-resistant steel bars 4 that can be welded to the kiln body are sequentially embedded on the left side of the heat-insulating composite precast block body 1 along the front-back direction. The design of multiple sets of heat-resistant steel bars 4 facilitates the welding and fixing of the heat-insulating composite precast block body 1 to the inner wall of the kiln body, improving the stability between each heat-insulating composite precast block body 1 and the kiln body, and effectively preventing the heat-insulating composite precast block body 1 from falling off or the kiln from collapsing due to excessive temperature inside the kiln.

[0021] As a preferred embodiment of this utility model, the number of heat-resistant steel bars 4 is at least two sets, and multiple sets of heat-resistant steel bars 4 are symmetrically placed on the left side of the heat-insulating composite precast block body 1. The limitation on the number and position of the heat-resistant steel bars 4 is to improve the stability of the heat-insulating composite precast block body 1 when welding to the inner wall of the kiln and to avoid detachment.

[0022] As a preferred embodiment of this utility model, the back of the card strip 3 has an arc-shaped structure so that the card strip 3 can be quickly engaged with the card slot 2, further improving the docking speed of the two sets of thermal insulation composite precast block bodies 1.

[0023] As a preferred embodiment of this utility model, the heat-insulating composite precast block body 1 is provided with heat-insulating cotton 5 through a preset groove. The design of heat-insulating cotton 5 and preset groove can block heat and effectively reduce the overall temperature of the kiln body. On the other hand, it can reduce the overall weight of the heat-insulating composite precast block body 1. The lightweight design can not only reduce the labor intensity of users when installing it, but also reduce costs.

[0024] As a preferred embodiment of this utility model, two sets of auxiliary grooves 6 are symmetrically provided on the right side of the top of the thermal insulation composite precast block body 1 along the front-back direction. The design of the auxiliary grooves 6 makes it convenient for users to pick up and fix the thermal insulation composite precast block body 1.

[0025] As a preferred embodiment of this utility model, both sides of the thermal insulation composite precast block body 1 have a Z-shaped structure to facilitate quick docking and installation of the thermal insulation composite precast block body 1.

[0026] The working principle of this utility model:

[0027] refer to Figs. 1-3Multiple sets of heat-resistant steel bars 4 can be used to directly weld and fix each set of heat-insulating composite precast block body 1 to the inner wall of the kiln. The locking strip 3 on one side of the heat-insulating composite precast block body 1 will be engaged with the locking groove 2 on another set of heat-insulating composite precast block body 1. The joint position is constructed with refractory mortar, which directly improves the stability between each heat-insulating composite precast block body 1 and the kiln, and simultaneously improves the stability between the two sets of heat-insulating composite precast block bodies 1. This can effectively prevent the heat-insulating composite precast block body 1 from falling bricks or collapsing the kiln due to excessive temperature inside the kiln, thus improving the overall safety of the lime rotary kiln. In addition, the heat insulation cotton 5 can further block the heat inside the kiln to ensure that the overall temperature of the kiln is within a controllable range.
