Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for industrial rotary kiln production equipment, specifically a rotary kiln head ring cleaning device. Background Technology

[0002] In modern industrial production, many industries generate complex byproducts such as zinc-containing sludge. Zinc-containing sludge falls under the category of environmental solid waste, containing not only zinc but also heavy metals such as lead and cadmium, as well as other harmful substances. Improper treatment of zinc-containing sludge can easily allow heavy metals and other pollutants to seep into soil and water bodies, causing serious and lasting pollution to the ecological environment and threatening human health. Currently, using rotary kilns to extract zinc oxide has become a common and effective resource recovery method for disposing of zinc-containing sludge, achieving zinc recycling while alleviating the pressure of environmental solid waste treatment to some extent.

[0003] However, in the production process of refining zinc oxide in a rotary kiln, the kiln head frequently encounters the problem of ring formation. The formation of rings at the kiln head is quite complex. On the one hand, the zinc-containing dust itself has a complex composition. Under the high-temperature calcination environment of the rotary kiln, some components may undergo complex physicochemical reactions to generate sticky, low-melting-point substances. These substances gradually accumulate at the kiln head, forming rings that are difficult to remove, thus affecting subsequent use. Utility Model Content

[0023] Please see Figure 1-4 As shown, a rotary kiln head ring cleaning device includes a cylinder 1 and a bottom plate 2, and further includes:

[0024] A tire 3 is fixed to the outer wall of the cylinder 1, a refractory material 4 is fixedly connected to the inner cavity of the cylinder 1, and a slag ring 5 is provided on the inner wall of the cylinder 1.

[0025] A base 6 is fixed to the top of the base plate 2. A bracket 7 is fixedly connected to the top of the base 6. A reciprocating mechanism 8 is provided in the inner cavity of the top of the base 6. The reciprocating mechanism 8 includes a geared motor 801, a first transmission rod 802, a first transmission wheel 803 and a belt 804. A chisel 9 is provided on the front end face of the bracket 7. A chisel tip 10 is fixed to one side of the chisel 9 by bolts.

[0026] The bottom of the geared motor 801 is fixedly connected to the base 6. The rear end face of the first transmission rod 802 is fixedly connected to the output shaft of the geared motor 801. The inner cavity of the first transmission wheel 803 is fixedly connected to the surface of the first transmission rod 802. The inner cavity of the belt 804 is meshed with the first transmission wheel 803. The top of the inner cavity of the belt 804 is meshed with the second transmission wheel 805. The inner cavity of the second transmission wheel 805 is fixedly connected to the second transmission rod 806. One side of the second transmission rod 806 is inserted into the inner cavity of the bracket 7 and fixedly connected to the turntable 807. The top of the turntable 807 is fixedly connected to the movable rod 808 through a bearing. The bottom of one side of the movable rod 808 is fixedly connected to the chisel 9 through a bearing. The front ends of both sides of the bracket 7 are fixedly connected to the positioning frames 12. The inner cavities of the positioning frames 12 are fixedly connected to the pulleys 13 through bearings. The surface of the chisel 9 is inserted into the inner cavity of the positioning frames 12 and slides in contact with the pulleys 13. When the slag ring 5 is generated in the inner cavity of the cylinder 1 and needs to be removed... First, the reduction motor 801 is started. The output shaft of the reduction motor 801 drives the first transmission rod 802 to rotate. At the same time, the first transmission rod 802 drives the first transmission wheel 803 to rotate. At the same time, the first transmission wheel 803 engages the belt 804 to rotate. At the same time, the belt 804 drives the second transmission wheel 805 to rotate. The rotation of the second transmission wheel 805 drives the second transmission rod 806 to rotate. At the same time, the rotation of the second transmission rod 806 drives the turntable 807 to rotate. At the same time, the rotation of the turntable 807 drives the movable rod 808 to reciprocate through the bearing. At the same time, the movable rod 808 drives the chisel 9 to reciprocate through the bearing. As the chisel 9 moves, it moves in a limited position within the cavity of the pulley 13. As the chisel 9 moves, it drives the chisel tip 10 to reciprocate and clean the slag ring 5 inside the cylinder 1, thus effectively and quickly cleaning the slag ring 5.

[0027] The lifting components 11 are located on both sides of the top of the base 6. The lifting components 11 include hydraulic rods 1101 and positioning plates 1102.

[0028] The bottom of the hydraulic rods 1101 is fixedly connected to the base 6, and the top of the hydraulic rods 1101 is fixedly connected to the bottom of the positioning plates 1102. The opposite sides of the two positioning plates 1102 are fixedly connected to the brackets 7. When it is necessary to adjust the height of the brackets 7 to facilitate the removal of the slag ring 5 at the high point inside the cylinder 1 by the drill bit 10, the hydraulic rods 1101 are first started. The extension and retraction of the two hydraulic rods 1101 drives the positioning plates 1102 to rise. While the positioning plates 1102 rise, the brackets 7 are raised and lowered. While the brackets 7 are raised and lowered, the components on the brackets 7 are adjusted in height, and the drill bit 10 is adjusted to a suitable height. This effectively adjusts the height of the drill bit 10 to facilitate the subsequent removal of the slag ring 5 at the high point.

[0029] Guide wheels 14 are fixedly connected to the four corners of the bottom of the base 6. The inner cavity of the guide wheel 14 is fitted with a guide rail 15, and the bottom of the guide rail 15 is fixedly connected to the base plate 2. By setting the guide wheel 14 and the guide rail 15 to work together, the base 6 can be moved easily, and the components on the base 6 can be moved back and forth, so as to achieve the effect of deep cleaning of the slag ring 5 in the future.

[0030] Working principle: First, install the base 6 on the guide rail 15, aligning the tip of the drill bit 10 with the slag ring 5 inside the cylinder 1. Then, connect the power supply and use the bottom guide wheels 14 to move the device to a suitable position near the cylinder 1 and fix it in place, ensuring the base 6 is stable and does not wobble. Next, when it is necessary to adjust the height of the support 7 to facilitate the removal of the slag ring 5 at a higher position inside the cylinder 1 by the drill bit 10, first activate the hydraulic rods 1101. The extension and retraction of the two hydraulic rods 1101 will cause the positioning plate 1102 to rise. Simultaneously, the positioning plate 1102 will raise and lower the support 7, and the components on the support 7 will adjust their height accordingly. The drill bit 10 is then adjusted to a suitable height to effectively facilitate the removal of the slag ring 5 at higher elevations. The geared motor 801 is then started, and its output shaft drives the first transmission rod 802 to rotate. Simultaneously, the first transmission rod 802 rotates, driving the first transmission wheel 803. The first transmission wheel 803, in turn, engages with the belt 804, causing it to rotate. The belt 804, in turn, drives the second transmission wheel 805 to rotate. The rotation of the second transmission wheel 805, in turn, drives the second transmission rod 806 to rotate. Simultaneously, the rotation of the second transmission rod 806 drives the turntable 80... 7 rotates, and while the turntable 807 rotates, the movable rod 808 reciprocates via the bearing. Simultaneously, the movable rod 808 reciprocates via the bearing, driving the chisel 9 to reciprocate. As the chisel 9 moves, it is limited and assisted in its movement within the pulley 13. This movement of the chisel 9 also drives the chisel tip 10 to reciprocate and clean the slag ring 5 inside the cylinder 1. The chisel 9 performs a high-frequency linear reciprocating motion, with its tip directly impacting the slag ring 5. Through continuous impact and scraping of the slag ring 5, the chisel 9 gradually breaks down and removes the slag ring 5, achieving an effective and quick cleaning effect. During the cleaning process, the operator can appropriately control the speed of the geared motor 801 and the working frequency of the chisel 9 according to the cleaning status of the slag ring 5 to achieve the best cleaning effect. After the cleaning is completed, the geared motor 801 is turned off, and then the guide wheel 14 is used to return the device to a suitable position nearby for the next use. It should be noted that the geared motor 801 is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine. It plays a role in matching the speed and transmitting torque between the prime mover and the working machine or actuator. It is widely used in modern machinery.
