Description

Technical Field

[0001] The utility model relates to the technical field of cement kiln cleaning, in particular to a device for cleaning cement kiln crust. Background Art

[0002] A cement kiln is a high-temperature furnace used in cement production. It primarily heats raw materials (such as limestone, clay, and iron ore) to high temperatures, enabling chemical reactions that ultimately form cement clinker. However, over time, a large amount of crust forms on the kiln's inner walls. This crust reduces the kiln's internal diameter, impairing ventilation, and directly impacting clinker production and quality. It also poses a significant threat to production safety.

[0003] Currently, most cement plants use manual scraping or spraying of chemical reagents. However, workers not only have to endure high temperatures when handling the process in the kiln, but the work is also very dangerous. The crust is prone to collapse, causing worker injuries, and the cost of manual cleaning is high. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a device for cleaning cement kiln crust.

[0005] The technical solution of the utility model is: a device for cleaning cement kiln crust, comprising a fixed cylinder with a liquid storage chamber, a crust cleaning disk rotatably arranged at one end of the fixed cylinder, and multiple groups of driving wheels radially arranged on the side wall of the fixed cylinder; a control rod is provided on one side of the driving wheel, a bevel gear ring is provided on one end face of the crust cleaning disk, a first bevel gear for meshing with the bevel gear ring is sleeved on the control rod, the crust cleaning disk is rotatably sealed and connected to an annular groove provided on one end face of the fixed cylinder, and the annular groove is connected to the liquid storage chamber through a liquid channel, one end of the control rod extends into the fixed cylinder and is rotatably sealed and connected to the liquid channel, the control rod has a through hole for rotatingly controlling the opening and closing of the corresponding liquid channel, the other end of the control rod is connected to the driving wheel through a worm gear and a worm, and a plurality of spraying ports are provided on the side wall of the crust cleaning disk, and the plurality of spraying ports are all connected to the annular groove.

[0006] Description: The above device scrapes off the crust by rotating the crust cleaning disc. At the same time, the crust cleaning disc can drive the control rod to rotate through the second bevel gear and the first bevel gear. On the one hand, the control rod can drive the driving wheel to rotate through the worm gear, so that the device as a whole moves in the cement kiln. On the other hand, the control rod can control the intermittent opening of the liquid channel to spray the cleaning liquid to further clean the crust, thereby improving the crust cleaning effect.

[0007] Furthermore, the fixed cylinder is provided with an air bag for applying pressure to the liquid storage cavity, and the crust cleaning disc is provided with a bulge for squeezing the air bag during its rotation cycle.

[0008] Description: When the crust cleaning disc rotates, the protrusions can intermittently squeeze the airbag, so that the airbag can inflate and pressurize the liquid storage chamber when the liquid channel is closed. Through the cooperation of the control rod and the airbag, the insufficient pressure in the liquid storage chamber caused by the continuous release of the cleaning liquid is avoided, which effectively extends the spraying time of the cleaning liquid.

[0009] Furthermore, a plurality of scrapers are slidably provided on the crust cleaning disk, and a plurality of second telescopic rods for pushing the corresponding scrapers to extend outward are provided on the crust cleaning disk.

[0010] Description: The second telescopic rod can push the scraper outward, so that the scraper can clean cement kilns of different diameters.

[0011] Furthermore, a plurality of third telescopic rods are provided on the side wall of the fixed cylinder, and an arc-shaped supporting piece for auxiliary supporting the fixed cylinder is provided at one end of the third telescopic rod.

[0012] Note: When the crust is relatively solid, the third telescopic rod can be used to drive the arc-shaped support piece to contact the inner wall of the cement kiln to assist in supporting the fixed cylinder and prevent the fixed cylinder from rotating due to the reaction force of the crust cleaning disc.

[0013] The beneficial effects of the utility model are:

[0014] (1) The utility model scrapes off the crust by rotating the crust cleaning disk. At the same time, the crust cleaning disk can drive the control rod to rotate. On the one hand, the control rod can drive the driving wheel to rotate, so that the device as a whole moves in the cement kiln. On the other hand, the control rod can control the liquid channel to open intermittently to spray the cleaning liquid to further clean the crust, thereby improving the crust cleaning effect.

[0015] (2) When the crust cleaning disk of the present invention rotates, the protrusion can intermittently squeeze the airbag, so that the airbag can inflate and pressurize the liquid storage chamber when the liquid channel is closed, avoiding insufficient pressure in the liquid storage chamber due to the continuous release of cleaning liquid.

DETAILED DESCRIPTION

[0024] The present invention will be described in further detail below in conjunction with specific implementation methods to better reflect the advantages of the present invention.

[0025] Example 1: Figure 1 As shown, a device for cleaning cement kiln crust comprises a fixed cylinder 1 with a liquid storage chamber, a crust cleaning disc 2 rotatably arranged at the left end of the fixed cylinder 1, and three sets of driving wheels 31 arranged radially and at 120° intervals on the side wall of the fixed cylinder 1; a protection chamber 11 is provided in the fixed cylinder 1, and a motor 12 for driving the crust cleaning disc 2 to rotate is provided in the protection chamber 11. The motor 12 adopts the existing technology product; the crust cleaning disc 2 is provided with three blades, such as Figure 2 As shown, a control rod 16 is provided on the left side of the driving wheel 31, a bevel gear ring 21 is provided on the right end face of the crust cleaning disc 2, and a first bevel gear 161 for engaging with the bevel gear ring 21 is provided on the control rod 16. Figure 3 、 Figure 4 As shown, the crust cleaning disk 2 is rotatably sealed with an annular groove 14 provided on the left end surface of the fixed cylinder 1, and the annular groove 14 is connected to the liquid storage chamber through a liquid channel 15. The lower end of the control rod 16 extends into the fixed cylinder 1 and is rotatably sealed with the liquid channel 15. The diameter of the control rod 16 is 2 cm larger than the inner diameter of the liquid channel 15. The control rod 16 has a through hole for rotating to control the opening and closing of the corresponding liquid channel 15. The upper end of the control rod 16 is connected to the drive wheel 31 through a worm gear 32 and a worm 33. Eight spray ports are provided on the side wall of the crust cleaning disk 2, and the eight spray ports are all connected to the annular groove 14;

[0026] There are three groups of drive wheels 31, each group includes two drive wheels 31 connected by a transmission belt. A movable plate 3 is provided below each group of drive wheels 31 and is rotatably connected thereto. The movable plate 3 is slidably connected to a limit rod provided on the fixed cylinder 1. The worm 33 is telescopically connected to the upper part of the control rod 16 through a spline. The worm gear 32 is rotatably provided on the movable plate 3, and the worm gear 32 and the left drive wheel 31 are driven by a transmission belt. An expansion mechanism for pushing the movable plate 3 to slide vertically is provided on the side wall of the fixed cylinder 1.

[0027] The unfolding mechanism includes a slider 34 that is laterally slidably arranged on the side wall of the fixed cylinder 1 and corresponds one-to-one to the movable plate 3, and a first telescopic rod 35 that is arranged on the fixed cylinder 1 and is used to push the slider 34 to slide laterally. The first telescopic rod 35 is a commercially available hydraulic rod; the slider 34 is hinged to the corresponding movable plate 3 through two connecting rods.

[0028] The working principle of the above device is as follows: the device is placed in the cement kiln, and the first telescopic rod 35 is extended to make the slider 34 slide to the left.
