[0002] Kiln mouth wear-resistant castable is a key refractory material used in the kiln mouth of cement rotary kilns. The production of kiln mouth wear-resistant castable is usually carried out inside the rotary kiln. However, protective devices are required during the production process of the rotary kiln to protect it and improve its service life. These protective devices include high temperature protection devices, dust and harmful gas protection devices, and chemical corrosion protection devices.

[0003] Chinese utility model patent with authorization announcement number "CN211626054U" is specifically "a rotary kiln cooling device", which includes a base, a horizontal moving mechanism, and an air-cooling device. The air-cooling device is installed on the base, and the horizontal moving mechanism drives the air-cooling device to move along the axial direction of the rotary kiln. The air-cooling device includes an air outlet pipe, a cooling air pipe, and an air supply device. The air outlet pipe is located below the rotary kiln, and multiple air outlets are evenly distributed on the side of the air outlet pipe near the rotary kiln. The air outlet pipe is also connected to the air supply device through the cooling air pipe, and the air supply device is used to provide cooling air.

[0004] Although the above-mentioned device cools the rotary kiln and extends its service life by cooperating with the air-cooling device and the horizontal moving mechanism, the cooling method is relatively simple and the cooling effect is poor. It cannot quickly lower the temperature of the rotary kiln, making it inconvenient to use. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] This utility model provides a technical solution: such as Figure 1 - Figure 5As shown in this embodiment, a protective device for producing wear-resistant castable at the kiln mouth of a cement rotary kiln includes: a base 1, a cooling box 4 fixedly connected to the upper end of the base 1, multiple fans 10 installed on one side of the cooling box 4, a guide plate 12 fixedly connected to one side of the inner wall of the cooling box 4, a guide plate 13 fixedly connected to the other side of the inner wall of the cooling box 4, the guide plate 13 and the guide plate 12 forming an S-shaped channel inside the cooling box 4, a heat absorption tube frame 11 is provided inside the cooling box 4, and the heat absorption tube frame 11 penetrates the guide plate 13 and the guide plate 12, a cooling box 3 is fixedly connected to the upper end of the cooling box 4, a rotary kiln body 2 is provided above the base 1, and the rotating drum of the rotary kiln body 2 penetrates the cooling box 3.

[0026] By turning on fan 10, gas is blown into cooling box 4. At the same time, water pump 14 is turned on to pump cooling water from water supply tank 5 into heat absorption tube frame 11 to cool the gas in cooling box 4. Guide plate 13 and guide plate 12 form an S-shaped channel in cooling box 4, which increases the flow time of gas in cooling box 4 and further cools the gas. The cooled gas enters cooling box 3 to cool the rotary kiln body 2. This structural design improves the cooling effect of rotary kiln body 2 and provides rotary kiln protection for rotary kiln body 2.

[0027] like Figures 1-3 As shown, a water supply tank 5 is fixedly connected to the other side of the upper end of the base 1. A water pump 14 is fixedly installed on one side of the water supply tank 5. The output end of the water pump 14 is fixedly connected to one side of the heat absorption tube frame 11. The output end of the heat absorption tube frame 11 is fixedly connected to the other side of the water supply tank 5. When the water pump 14 is turned on, the cooling water in the water supply tank 5 is pumped into the heat absorption tube frame 11. The heat absorption tube frame 11 cools the gas in the cooling box 4, thereby improving the cooling effect of the rotary kiln body 2.

[0028] like Figures 1-4 As shown, a cooling device 17 is fixedly installed on the top of the water supply tank 5, and a motor 16 is fixedly installed in the middle of one side of the water supply tank 5. A stirring frame 15 is rotatably connected to the middle of the inside of the water supply tank 5. The output end of the motor 16 is connected to one end of the stirring frame 15 through a coupling. By turning on the cooling device 17, the cooling water in the water supply tank 5 is cooled down. At the same time, the motor 16 is turned on, so that the stirring frame 15 stirs the water in the cooling tank 4, thereby improving the cooling effect of the cooling water in the water supply tank 5. The cooling device 17 can be a semiconductor heat dissipation device, and its cooling end is inside the water supply tank 5.

[0029] like Figure 2 As shown, baffles 9 are fixedly connected to both sides of the inner wall of the cooling chamber 3. Through the structural design of the two baffles 9, the gas entering the cooling chamber 3 stays in the cooling chamber 3 for a longer time, thereby improving the cooling effect.

[0030] like Figure 1 , Figure 2and Figure 5 As shown, multiple fans 7 are installed on one side of the cooling box 3, and an exhaust port is opened through one side of the cooling box 3. A heat absorption plate 19 is fixedly installed on the top of the cooling box 3, and multiple heat dissipation fins 6 are fixedly connected to the upper end of the heat absorption plate 19.

[0031] Through the structural design of fan 7, heat absorption plate 19 and heat dissipation fins 6, when the rotary kiln body 2 is running, the heat generated by the rotary kiln body 2 will flow upward. When fan 7 is turned on, the heat in the cooling box 3 will be quickly discharged. When the heat comes into contact with the heat absorption plate 19, the heat absorption plate 19 will absorb the heat. The heat dissipation fins 6 increase the contact area with the air and discharge the heat absorbed by the heat absorption plate 19. The fan 7 and the heat absorption plate 19 work together to further improve the cooling effect of the rotary kiln body 2.

[0032] like Figure 2 and Figure 5 As shown, a mounting frame 18 is fixedly connected to the other side of the cooling box 3. A filter plate 8 is slidably connected to the inner wall of the mounting frame 18. The filter plate 8 is slidably connected inside the mounting frame 18, which facilitates the replacement and cleaning of the filter plate 8.

[0033] This utility model provides a protective device for the production of wear-resistant castable at the kiln mouth of a cement rotary kiln. The specific working principle is as follows:

[0034] When the rotary kiln body 2 produces wear-resistant castable at the kiln opening, it generates heat during operation. Fan 2 10 is turned on to blow gas into the cooling box 4. At the same time, water pump 14 is turned on to pump cooling water from water supply tank 5 into heat absorption tube frame 11 to cool the gas in the cooling box 4. Guide plate 2 13 and guide plate 1 12 form an S-shaped channel in the cooling box 4, which increases the flow time of the gas in the cooling box 4, further cooling the gas. The cooled gas enters the cooling box 3 to cool the rotating drum of the rotary kiln body 2. At the same time, the heat generated by the rotary kiln body 2 will flow upward. Fan 1 7 is turned on to quickly expel the heat from the cooling box 3. When the heat comes into contact with the heat absorption plate 19, the heat absorption plate 19 absorbs the heat. The heat dissipation fins 6 increase the contact area with the air and expel the heat absorbed by the heat absorption plate 19. Fan 1 7 and heat absorption plate 19 work together to further improve the cooling effect of the rotary kiln body 2.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
