Description

Technical Field

[0001] This utility model relates to the field of rotary kiln control, and in particular to a control device for the up-and-down reciprocating motion of a rotary kiln. Background Technology

[0002] Rotary kilns are used in the metallurgical industry for the magnetization roasting of lean iron ore in steel plants. Cement kilns are mainly used for calcining cement clinker and are divided into two main categories: dry-process cement kilns and wet-process cement kilns. Metallurgical and chemical kilns are mainly used in the metallurgical industry for the magnetization roasting of lean iron ore in steel plants; the oxidation roasting of chromium and nickel iron ore; the roasting of high-metallurgical-grade ores in refractory material plants; the roasting of clinker and aluminum hydroxide in aluminum plants; and the roasting of chromite sand and chromite powder in chemical plants. Rotary kilns have a 3.5% inclination and weigh up to 1000 tons with refractory materials. Excessive upward or downward forces, without effective detection methods and adjustment schemes, can lead to uncontrolled vertical movement of the kiln. Both excessive upward and downward forces can damage related equipment such as thrust rollers, support rollers, kiln head, and kiln tail. Furthermore, in recent years, with the wear and tear of support rollers and thrust rollers, and the subsequent displacement of the kiln body, transmission equipment malfunctions have become more frequent, leading to unstable production.

[0003] Therefore, it is necessary to provide a control device for the reciprocating motion of a rotary kiln to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a control device for the reciprocating motion of a rotary kiln, including a base, a support column fixedly connected to the top of the base, a top plate fixedly connected to the top of the support column, a pressure detection host fixedly installed on the top of the top plate, a display on the front of the pressure detection host, a first hydraulic thrust roller fixedly installed at the bottom of the top plate, a first blocking wheel installed at the bottom of the first hydraulic thrust roller, a pressure sensor fixedly installed at one end of the first hydraulic thrust roller, a load-bearing wheel provided on the top of the base, a kiln body movably sleeved on the top of the load-bearing wheel, a positioning sleeve fixedly sleeved on the outside of the kiln body, a second hydraulic thrust roller fixedly installed on the top of the base, and a second blocking wheel installed on the top of the second hydraulic thrust roller.

[0005] Preferably, the input terminal of the pressure detection host is connected to the output terminal of the pressure sensor, and the output terminal of the pressure detection host is connected to the input terminal of the display.

[0006] Preferably, the number of the load-bearing rollers is eight, and the eight load-bearing rollers are evenly distributed around the kiln body.

[0007] Preferably, there are two hydraulic wheel catchers, and the two hydraulic wheel catchers are symmetrically distributed with the positioning sleeve as the axis of symmetry.

[0008] Preferably, there are two first hydraulic wheel stops, and the two first hydraulic wheel stops are located directly above the second hydraulic wheel stop.

[0009] Compared with related technologies, the control device for the up-and-down reciprocating motion of a rotary kiln provided by this utility model has the following beneficial effects:

[0010] This utility model provides a control device for the reciprocating motion of a rotary kiln. By setting up a pressure detection host, when the kiln body is rotating, the pressure sensor and the pressure detection host are activated. When the kiln body deviates during rotation, the positioning sleeve can be driven to squeeze the No. 1 blocking wheel, that is, to squeeze the No. 1 hydraulic blocking wheel. At this time, the pressure sensor can continuously monitor the internal pressure of the No. 1 hydraulic blocking wheel, that is, monitor the kiln body deviation amplitude. This avoids the problem of large kiln body deviation amplitude when the No. 1 blocking wheel is severely worn, which may cause damage to the kiln head, kiln tail and other related equipment, thereby improving the monitoring and protection effect of the equipment during the operation of the rotary kiln.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of a preferred embodiment of a control device for the reciprocating motion of a rotary kiln provided by this utility model; Figure 2 for Figure 1 The figure shows a front view of the base in a control device for the reciprocating motion of a rotary kiln. Figure 3 for Figure 1The image shows a front view of a control device for the reciprocating motion of a rotary kiln. The control device includes a base 1, a support column 2 fixedly connected to the top of the base 1, a top plate 3 fixedly connected to the top of the support column 2, a pressure detection host 4 fixedly mounted on the top of the top plate 3, a display 5 on the front of the pressure detection host 4, a first hydraulic thrust roller 6 fixedly mounted on the bottom of the top plate 3, a first blocking wheel 7 mounted on the bottom of the first hydraulic thrust roller 6, a pressure sensor 8 fixedly mounted on one end of the first hydraulic thrust roller 6, a load-bearing wheel 9 on the top of the base 1, a kiln body 10 movably sleeved on the top of the load-bearing wheel 9, a positioning sleeve 11 fixedly sleeved on the outside of the kiln body 10, a second hydraulic thrust roller 12 fixedly mounted on the top of the base 1, and a second thrust roller 13 mounted on the top of the second hydraulic thrust roller 12.

[0017] The input terminal of the pressure detection host 4 is connected to the output terminal of the pressure sensor 8, and the output terminal of the pressure detection host 4 is connected to the input terminal of the display 5. By setting the pressure detection host 4, when the kiln body 10 is rotating, the pressure sensor 8 and the pressure detection host 4 are activated. When the kiln body 10 rotates and deviates, the positioning sleeve 11 can be driven to squeeze the first blocking wheel 7, that is, squeeze the first hydraulic blocking wheel 6. At this time, the pressure sensor 8 can continuously monitor the internal pressure of the first hydraulic blocking wheel 6, that is, monitor the displacement amplitude of the kiln body 10. This avoids the problem that the kiln body 10 will deviate too much when the first blocking wheel 7 is severely worn, which may cause damage to the kiln head, kiln tail and other related equipment. This improves the monitoring and protection effect of the equipment during the operation of the rotary kiln.

[0018] There are eight load-bearing wheels 9, which are evenly distributed around the kiln body 10. By setting the load-bearing wheels 9, when the kiln body 10 is rotating, the eight load-bearing wheels 9 can limit the rotating kiln body 10 in multiple directions, thus avoiding the problem of up and down fluctuation when the kiln body 10 is rotating, thereby improving the stability of the kiln body 10 during operation.

[0019] There are two hydraulic thrust rollers 12, which are symmetrically distributed about the positioning sleeve 11. By setting the hydraulic thrust rollers 12, when the positioning sleeve 11 is used for blocking and limiting, the two hydraulic thrust rollers 12 can block both sides of the positioning sleeve 11, so that the horizontal displacement of the positioning sleeve 11 can be limited between the two hydraulic thrust rollers 12, thereby improving the stability of the horizontal displacement of the kiln body 10.

[0020] There are two No. 1 hydraulic thrusters 6, which are located directly above No. 2 hydraulic thrusters 12. By setting up No. 1 hydraulic thrusters 6, when the kiln body 10 is rotating, the two No. 1 hydraulic thrusters 6 can limit the positioning sleeve 11 from the top of the kiln body 10, thus avoiding the problem of poor stability when the positioning sleeve 11 is limited and blocked in a single direction.

[0021] The working principle of the control device for the up-and-down reciprocating motion of a rotary kiln provided by this utility model is as follows:

[0022] First, when the kiln body 10 rotates, the pressure sensor 8 and the pressure detection host 4 are activated. When the kiln body 10 deviates during rotation, it drives the positioning sleeve 11 to press against the first blocking wheel 7, that is, to press against the first hydraulic thrust wheel 6. At this time, the pressure sensor 8 can continuously monitor the internal pressure of the first hydraulic thrust wheel 6, that is, monitor the deviation of the kiln body 10. This avoids the problem of the kiln body 10 deviating too much when the first blocking wheel 7 is severely worn, which could lead to damage to the kiln head, kiln tail and other related equipment. This improves the monitoring and protection effect of the equipment during the operation of the rotary kiln. When the kiln body 10 rotates, the eight load-bearing wheels 9 can press against the rotating kiln body 10. Multi-directional limiting is implemented to avoid the problem of vertical fluctuation when the kiln body 10 rotates, thereby improving the stability of the kiln body 10 during operation. When the positioning sleeve 11 is used for blocking and limiting, the two No. 2 hydraulic thrust rollers 12 can block the two sides of the positioning sleeve 11, so that the horizontal displacement of the positioning sleeve 11 is limited between the two No. 2 hydraulic thrust rollers 12, thereby improving the stability of the horizontal displacement of the kiln body 10. When the kiln body 10 is rotating, the two No. 1 hydraulic thrust rollers 6 can limit the positioning sleeve 11 from the top of the kiln body 10, thus avoiding the problem of poor stability when the positioning sleeve 11 is limited and blocked in a single direction.

[0023] Compared with related technologies, the control device for the up-and-down reciprocating motion of a rotary kiln provided by this utility model has the following beneficial effects:

[0024] By setting up the pressure detection host 4, when the kiln body 10 is rotating, the pressure sensor 8 and the pressure detection host 4 are activated. When the kiln body 10 rotates and deviates, the positioning sleeve 11 is driven to squeeze the first blocking wheel 7, that is, to squeeze the first hydraulic blocking wheel 6. At this time, the pressure sensor 8 can continuously monitor the internal pressure of the first hydraulic blocking wheel 6, that is, monitor the deviation of the kiln body 10. This avoids the problem that the kiln body 10 deviates too much when the first blocking wheel 7 is severely worn, which may cause damage to the kiln head, kiln tail and other related equipment. This improves the monitoring and protection effect of the equipment during the operation of the rotary kiln.
