Description

Technical Field

[0001] The present invention relates to the technical field of rotary kiln, and in particular to a steam flow regulating control device and a control method for a rotary kiln. Background Art

[0002] A rotary kiln refers to a rotating calcining kiln (commonly known as a rotary kiln), which belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to the different materials they process. Cement kilns are mainly used to calcine cement clinker, and are divided into two categories: dry-process cement kilns and wet-process cement kilns. Metallurgical chemical kilns are mainly used for magnetization roasting of lean iron ore in steel plants in the metallurgical industry; oxidation roasting of chromium and nickel iron ores; roasting of high-alumina vanadium ore in refractory plants and roasting of clinker and aluminum hydroxide in aluminum plants; and roasting of chromium ore sand and chromium ore powder and other minerals in chemical plants. Lime kilns (i.e. active lime kilns) are used to roast active lime and light-burned dolomite for use in steel plants and ferroalloy plants.

[0003] At present, the waste heat of most rotary kiln exhaust gas and tail can be recycled and utilized, and considerable economic and environmental benefits have been achieved. The common way to recover waste heat from rotary kilns is to use waste heat to generate hot water and steam to meet the needs of hot water and heating for production and life. At the same time, steam can be introduced into the steam turbine generator to drive the turbine to rotate for power generation. Generally, a boiler steam flow control device is installed to control the flow of steam. The boiler steam flow control device currently used is generally a valve. The valve core of the valve is generally spherical or plate-shaped. There is a through hole in the middle of the sphere. Steam passes through the through hole. The flow of steam is controlled by rotating the valve core. When the valve core deflects, the valve core will block the passage for steam flow, and the valve core will affect the speed of steam flow. At the same time, the steam hits the surrounding of the valve core and easily causes wear of the valve body. After the valve body is worn, the entire valve needs to be replaced, which is inconvenient to operate and does not meet the requirements of current use. For this reason, we provide a steam flow regulation control device and control method for rotary kilns. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a steam flow regulation control device and a control method for a rotary kiln, which solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A steam flow regulating and controlling device for a rotary kiln, comprising a valve body, a fixed guide ring is fixedly sleeved inside the valve body, a horizontal valve core and a vertical valve core are clamped inside the valve body, a transverse limit shell and a vertical limit shell are fixedly connected to the outer surface of the valve body, a transverse screw is movably sleeved on the side of the horizontal valve core, a T-shaped gear sleeve 1 and a T-shaped gear sleeve 2 are clamped on the outside of the transverse screw, a driving motor 1 is fixedly installed on the side of the transverse limit shell, a driving gear 1 is fixedly sleeved on the output shaft of the driving motor 1, and the driving gear 1 is meshed with the driving motor 1, a vertical screw is movably sleeved on the outer side of the vertical valve core, a T-shaped gear sleeve 3 and a T-shaped gear sleeve 4 are clamped on the outside of the vertical screw, a driving motor 2 is fixedly installed on the right side of the vertical limit shell, a driving gear 2 is fixedly sleeved on the output shaft of the driving motor 2, and the driving gear 2 is meshed with the T-shaped gear sleeve 4.

[0006] Optionally, the horizontal valve core and the vertical valve core are distributed alternately, and a conical aperture is arranged inside the horizontal valve core and the vertical valve core, and the aperture gradually decreases from left to right. By setting a circular aperture inside the horizontal valve core and the vertical valve core, the aperture inside the horizontal valve core and the vertical valve core gradually decreases from left to right until it is completely closed, which reduces the resistance to steam, avoids steam hitting the valve core, and improves the service life of the valve core.

[0007] Optionally, the horizontal valve core and the vertical valve core are both semicircular arc-shaped, the horizontal valve core is symmetrically distributed front to back, and the vertical valve core is symmetrically distributed up to down.

Since the transverse screw is threadably sleeved with the transverse limit shell, the transverse screw will drive the horizontal valve core to move outward.

[0010] Optionally, the bottom of the T-shaped gear sleeve is movably sleeved with a lifting sleeve, the side of the lifting sleeve is fixedly connected to a Z-shaped bracket, the surface of the lateral limiting shell is fixedly installed with a micro-telescopic rod, the output shaft of the micro-telescopic rod is fixedly connected to the end of the Z-shaped bracket away from the lifting sleeve, and the lifting sleeve is provided and the micro-telescopic rod is used to push the Z-shaped bracket to move upward, so as to lift the T-shaped gear sleeve upward, so that the T-shaped gear sleeve one can mesh with the T-shaped gear sleeve two, so that the T-shaped gear sleeve two drives the T-shaped gear sleeve one to rotate, thereby facilitating the corresponding horizontal valve core to open outward.

[0011] Optionally, the T-shaped gear sleeve three is movably sleeved inside the vertical limit shell and can slide up and down, the T-shaped gear sleeve four is movably sleeved inside the vertical limit shell, the T-shaped gear sleeve three and the T-shaped gear sleeve four are staggered with each other, and by setting the T-shaped gear sleeve three, the function of the T-shaped gear sleeve three is the same as that of the T-shaped gear sleeve one. When the T-shaped gear sleeve three rotates, the T-shaped gear sleeve three will drive the vertical screw to rotate together. Since the vertical screw is threadedly sleeved with the vertical limit shell, the vertical screw will drive the vertical valve core to move outward.

[0012] Optionally, the external movable sleeve of the T-shaped gear sleeve three is connected with a lifting sleeve, and the structure of the T-shaped gear sleeve three is exactly the same as that of the T-shaped gear sleeve one. The Z-shaped bracket is pushed upward by the micro-telescopic rod to lift the T-shaped gear sleeve three upward, so that the T-shaped gear sleeve three can be meshed with the T-shaped gear sleeve four, so that the T-shaped gear sleeve four drives the T-shaped gear sleeve three to rotate, thereby facilitating the opening of the corresponding vertical valve core outward.
