Description

Technical Field

[0001] The utility model belongs to the technical field of steel slag treatment, and particularly relates to a dust removal device for steel slag treatment. Background Technique

[0002] In the process of steel production, as a by-product, steel slag is often accompanied by a large amount of dust generation during the treatment process. These dusts not only cause serious environmental pollution, but also affect the health and production efficiency of workers. Therefore, the dust removal technology in the process of steel slag treatment has always been the focus of attention in the steel industry.

[0003] Traditional dust removal equipment, such as cyclone separators and bag filters, has unsatisfactory effects when dealing with the fine dust generated by steel slag. The cyclone separator mainly deals with dust with larger particle sizes, generally 50 microns and above; while the bag filter has a higher filtration efficiency, but the filter bags need to be replaced regularly, resulting in higher maintenance costs. At the same time, the above-mentioned equipment is large in volume and high in cost, and it cannot achieve good treatment effects for the dust generated during the transportation of steel slag. Therefore, some steel plants use fog guns instead, but the atomization range of the fog gun is limited and it cannot effectively remove dust for a long conveyor belt. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems of poor dust treatment effect, high cost and limited application range of treatment equipment during the transportation of existing steel slag, and provides a dust removal device for steel slag treatment, which can effectively treat the dust generated during the treatment of steel slag, improve the dust removal effect, save the dust removal cost, expand the application range of the dust removal equipment, and make it applicable to the dust removal of a long conveyor belt.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A dust removal device for steel slag treatment includes a spray pipe, a group of atomizing nozzles are arranged on the spray pipe, a connecting pipe is connected to each side of the spray pipe, and each connecting pipe is further connected to a hose. Lifting mechanisms are respectively connected to both ends of the spray pipe. The lifting mechanism includes a top frame, a reduction motor and a pair of parallel support frames are fixed below the top frame. A horizontal rotating shaft is rotatably connected between the two support frames. One end of the rotating shaft is fixedly connected to the output end of the reduction motor. A reel is sleeved on the rotating shaft, a pulling rope is wound on the reel, and the lower end of the pulling rope is fixed on the spray pipe.

[0007] Furthermore, the spray pipe has a square structure and is arranged above the conveyor belt for steel slag treatment, and the spraying ports of the atomizing nozzles are arranged directly opposite to the conveyor belt.

[0008] Furthermore, the connecting pipe and the hose are connected via a first pipe joint, a second pipe joint is provided at one end of the hose away from the spray pipe, and the hose is connected to an external water pipe via the second pipe joint.

[0009] Furthermore, the hose is a corrugated hose or a rubber hose.

[0010] Furthermore, the lower part of the support frame is rotatably connected to a toggle assembly for toggling the pull rope to swing back and forth, and the toggle assembly is transmission-connected to the rotating shaft through a transmission mechanism.

[0011] Furthermore, the toggle assembly includes a crankshaft, on which a sliding sleeve is sleeved, and the two form a sliding guide fit. A guide wheel is rotatably connected to the outer wall of the sliding sleeve through a bearing, and the pull rope is arranged in a guide groove of the guide wheel.

The driving wheel is fixed to the end of the rotating shaft, the driven wheel is fixed to the end of the crankshaft, and a transmission belt is connected between the driving wheel and the driven wheel.

When the sprayed steel slag is processed in the next step, the generation of dust can also be reduced. The space occupancy rate is low, the operation is convenient and the cost is low, and the dust removal effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the present invention more clear, a dust removal device for steel slag treatment of the present invention is further described below in conjunction with the accompanying drawings. The specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0020] See alsoFigure 1 , a dust removal device for steel slag treatment, characterized in that:

[0021] It includes a spray pipe 1, a group of atomizing nozzles 2 are evenly spaced and installed at the bottom of the spray pipe 1, and two lifting mechanisms 5 are also provided at both ends of the spray pipe 1. Both ends of the spray pipe 1 are respectively connected to a connecting pipe 3. A hose 4 is installed at the end of the connecting pipe 3 away from the spray pipe 1, and the two are connected through a first pipe joint 6. A second pipe joint 7 is installed at the end of the hose 4 away from the spray pipe 1, and it is connected to an external water pipe through the second pipe joint 7 for water supply. The external water pipe is connected to a water source, which can be directly connected to a tap water pipe. A regulating valve can be set on the tap water pipe to control the flow rate, or a water storage tank can be used for water supply. The external water pipe is connected to a water suction pump, which can also achieve water supply.

[0022] See Figure 1 and Figure 2 , the hose 4 is made of a corrugated pipe or a rubber hose. When setting the corrugated pipe or the rubber hose, a telescopic allowance needs to be left to ensure that there is a distance for expansion and contraction during lifting.

[0023] See Figure 1 and Figure 2 , the spray pipe 1 has a "mouth" - shaped structure, which is located above the conveyor belt for steel slag treatment. The "mouth" - shaped spray pipe 1 can cover the periphery of the conveyor belt, thereby improving the effect of spray dust removal. When the conveyor belt is inclined, by adjusting the two lifting mechanisms 5, the angle of the spray pipe 1 can be changed to make the spray pipe 1 as parallel to the conveyor belt as possible. In this way, the steel slag on the conveyor belt can be spray - dusted. When the spray - treated steel slag is further processed, the generation of dust will also be reduced.

[0024] In this embodiment, the lifting mechanism 5 adopts an electric hoist, and the electric hoist is fixed above the spray pipe 1 to achieve rapid lifting through the electric hoist.

[0025] Participate in Figure 3 , the lifting mechanism 5 includes a top frame 51, a reduction motor 52 and a support frame 53 are fixed at the bottom of the top frame 51. A rotating shaft 54 is rotatably installed on the support frame 53. The rotating shaft 54 is fixedly connected to the output end of the reduction motor 52. A winding drum 55 is fixedly sleeved on the rotating shaft 54. A pulling rope 56 is fixedly wound on the winding drum 55. The lower end of the pulling rope 56 is fixed to the top of the spray pipe 1. This solution is an improvement on the structure of the electric hoist and is equivalent to an electric hoist.

[0026] See Figure 3 , Figure 4 and Figure 5The lower side of the support frame 53 is rotatably mounted with a toggle assembly 57, which is used to toggle the pull rope 56 to make the pull rope 56 swing back and forth. The toggle assembly 57 is connected to the rotating shaft 54 ​​through a transmission mechanism 58. It is worth noting that the pull rope 56 is Y-shaped. Figure 5 As shown, the two lower ends of the pull rope 56 are fixed at the front and rear tops of the drum 55 to improve the stability of lifting. This solution has an additional toggle component 57 compared to the electric hoist. After the height adjustment of the spray pipe 1 is completed, when spraying, the reduction motor 52 rotates forward and reverse, such as rotating forward 180° and then reverse 180°. In this way, the overall height does not change much, but at this time the toggle component 57 can realize the toggle action, thereby realizing a slight swing of the spray pipe 1 back and forth. After the spray pipe 1 swings, the range of spraying will increase, which can improve the effect of spraying dust removal to a certain extent.

[0027] See also Figure 4 The toggle assembly 57 includes a crankshaft 571, a sleeve 572 is slidably mounted on the crankshaft 571, a guide wheel 573 is rotatably mounted on the outer wall of the sleeve 572 through a bearing, and the pull rope 56 slides in the guide groove 573a of the guide wheel 573. The guide wheel 573 can change according to the position of the pull rope 56, and the guide wheel 573 can also rotate to reduce the wear on the pull rope 56.

[0028] See also Figure 3 The transmission mechanism 58 adopts a belt transmission mechanism, which includes a driving wheel 581, a driven wheel 582 and a transmission belt 583. The driving wheel 581 is fixed on the rotating shaft 54, the driven wheel 582 is fixed on the crankshaft 571, and the driving wheel 581 and the driven wheel 582 are sleeved with a transmission belt 583.

[0029] The working principle and use process of the utility model are as follows:

[0030] The spray pipe 1 is arranged above the slag conveyor belt. When the conveyor belt is inclined, the angle of the spray pipe 1 can be changed by adjusting the two lifting mechanisms 5, so that the spray pipe 1 can be made parallel to the conveyor belt as much as possible, so that the slag on the conveyor belt can be sprayed for dust removal. When the sprayed slag is processed in the next step, the generation of dust can also be reduced. After the height adjustment of the spray pipe 1 is completed, during spraying, the reduction motor 52 rotates forward and reverse, for example, rotates forward 180° and then reverses 180°, so that the overall height does not change much, but at this time the toggle assembly 57 can realize the toggle action, thereby realizing a slight swing of the spray pipe 1 back and forth. After the spray pipe swings, the range of spraying will increase, which can improve the effect of spraying dust removal to a certain extent.

[0031] In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
