Description

Technical Field

[0001] This utility model belongs to the field of preheater cleaning technology, specifically relating to a preheater scale removal facility. Background Technology

[0002] Preheaters are key equipment in industries such as cement and chemicals, used to preheat materials to improve production efficiency. A preheater mainly consists of a preheating chamber, cyclone separator, connecting ducts, discharge chute, airlock valve, and material spreading plate. During operation, preheaters are prone to forming a crust, which affects preheating efficiency and material flow, and can even lead to equipment failure.

[0003] When cleaning the scale buildup in the preheater, compressed air and water cannons are mainly used for maintenance and cleaning of the scale buildup in the preheater system. When the scale is large and hard, the labor intensity of cleaning with compressed air and water cannons is high, the operation time is long, and the cleaning is not thorough, which is not conducive to the long-term stable operation of the preheater. At the same time, there are too few cleaning holes in the parts of the preheater system that are prone to scale buildup, and the cleaning facilities are incomplete, resulting in many maintenance blind spots. Only a small number of scale buildup areas can be cleaned and maintained, failing to achieve full coverage of scale maintenance and cleaning of the preheater system. This can easily lead to preheater blockage process failures, especially when the use of alternative fuels causes the scale buildup in the preheater system to grow faster. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a preheater scale removal facility, thereby solving the problems mentioned in the background art.

[0005] This utility model provides a preheater scale removal device, including a high-pressure water gun installed on the preheater, a high-pressure water pipe matched with the high-pressure water gun, and a foot pedal connected to the high-pressure water gun and used to control the high-pressure water gun switch. The high-pressure water pipe, high-pressure water gun and foot pedal are distributed on multiple floors of the preheater. The high-pressure water pipes on each floor are connected by connecting pipes, and different lengths of cleaning rods are installed on the floors where the high-pressure water pipes are laid. The cleaning rods are used to assist the high-pressure water gun in cleaning the scale inside the preheater.

[0006] Preferably, each of the high-pressure water pipes is equipped with a manual valve for controlling the flow of high-pressure water.

[0007] Preferably, there are three cleaning rods, which are installed on the 3rd, 4th and 6th floors of the preheater, respectively, and their lengths are 2.5m, 4m and 6m respectively.

[0008] Preferably, the chute section of the preheater is provided with multiple cleaning holes evenly distributed at intervals of 2.5-3m.

[0009] Preferably, the preheater is equipped with cleaning doors at the material distribution box, air inlet, and feed inlet to facilitate the cleaning of accumulated material or crusts in these areas.

[0010] Preferably, the working pressure of the high-pressure water gun can be set to 50-60 MPa.

[0011] The beneficial effects of this utility model are: by distributing the high-pressure water gun, high-pressure water pipe and foot pedal on multiple floors of the preheater, efficient cleaning of the scale inside the preheater is achieved, improving the flexibility and efficiency of cleaning; the setting of manual valves allows the operator to precisely control the flow of high-pressure water, improving the safety and flexibility of cleaning.

[0012] By setting cleaning rods of different lengths and multiple cleaning holes distributed in the preheater chute section, the cleaning work is made more comprehensive and thorough, improving the stability and operating efficiency of the preheater.

[0013] By setting up cleaning gates, operators can easily access key parts of the preheater for cleaning, improving the convenience and efficiency of cleaning. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0020] like Figure 1-4As shown, a preheater scale removal device includes a high-pressure water gun 2 installed on the preheater 1, a high-pressure water pipe 3 matched with the high-pressure water gun 2, and a foot pedal connected to the high-pressure water gun 2 and used to control the switch of the high-pressure water gun 2. The high-pressure water pipe 3, the high-pressure water gun 2, and the foot pedal are distributed on multiple floors of the preheater 1. The high-pressure water pipe 3 on each floor is connected by a connecting pipe 4, and different lengths of cleaning rods 5 are installed on the floors where the high-pressure water pipe 3 is laid. The cleaning rods 5 are used to assist the high-pressure water gun 2 in cleaning the scale inside the preheater 1. The high-pressure water gun 2, the high-pressure water pipe 3, and the foot pedal are also distributed on the 3rd, 4th, and 6th floors of the preheater 1 and possibly at a fixed end. Compared with the prior art, this device achieves effective cleaning of the scale inside the preheater 1.

[0021] Furthermore, such as Figure 1-4 As shown, each of the high-pressure water pipes 3 is equipped with a manual valve 6 to control the flow of high-pressure water. For example, when cleaning the crust on the 6th floor, it is only necessary to open the manual valve 6 on the high-pressure water pipe 3 on the 6th floor, and close the high-pressure water pipes 3 on other floors. The water flows along the connecting pipe 4 and the high-pressure water pipe 3 to the high-pressure water gun 2 on the 6th floor. The high-pressure water gun 2 can be turned on and off by stepping on the foot pedal. By cleaning the crust or material inside the preheater 1 on the 6th, 4th and 3rd floors of the preheater 1 in sequence, the blind spots of cleaning can be reduced and the cleaning efficiency of the preheater 1 can be improved.

[0022] Furthermore, such as Figure 3-4 As shown, there are three cleaning rods 5, installed on the 3rd, 4th, and 6th floors of the preheater 1, with lengths of 2.5m, 4m, and 6m respectively. Each cleaning rod 5 can be fixedly installed on a mounting plate 14 with a slot 13 at each floor, suspending the cleaning rod 5 for easy access. Alternatively, the cleaning rods 5 can be installed in other ways, such as by using a support frame. By using cleaning rods 5 of different lengths, when cleaning on the 6th floor, a 6-meter cleaning rod 5 can clean the 6th, 5th, and 4th floors. In addition, the cleaning rod 5 can clean the scale on the top layer of the preheater 1. When it is on the 4th floor of the preheater 1, the 4-meter cleaning rod 5 can clean the scale around the 4th floor and the 3rd floor. When cleaning on the 3rd floor, the 2.5-meter cleaning rod 5 can clean the scale around the 3rd floor, the 2nd floor, and even the 1st floor. This allows the operator to clean the scale in different locations, improving the accuracy and efficiency of the cleaning. The setting of cleaning rods 5 of different lengths also takes into account the differences in the internal structure of the preheater 1, ensuring the comprehensiveness and thoroughness of the cleaning work.

[0023] Furthermore, such as Figure 2As shown, the preheater 1 has multiple cleaning holes 7 evenly distributed in the chute 12 section, with a spacing of 2.5-3m. The chute 12 includes C4 chute and C5 chute sections, which facilitates the operator to clean and cover the crust and material buildup in the chute 12 section.

[0024] Furthermore, such as Figure 2 As shown, the preheater 1 is equipped with cleaning doors 8 at the material distribution box 9, air inlet 10 and feed inlet 11. The cleaning doors 8 facilitate the cleaning of accumulated material or crusts in these parts. At the same time, the cleaning doors 8 also make it easier for operators to inspect and maintain the inside of the preheater 1, thus extending the service life of the preheater 1.

[0025] Furthermore, the working pressure of the high-pressure water gun 2 can be set to 50-60MPa, ensuring that the high-pressure water flow has sufficient flushing force to effectively clean the crust and accumulated material inside the preheater 1. The appropriate working pressure also improves the cleaning efficiency and reduces the time and labor costs required for cleaning.
