Description

Technical Field

[0001] This utility model belongs to the field of steel slag hot curing technology, specifically relating to a feeding device for steel slag hot curing. Background Technology

[0002] Steel slag is a major solid waste generated during the steel industry production process. Approximately 0.1-0.15 tons of steel slag are produced for every ton of steel produced. If steel slag is directly piled up without proper treatment, it will not only occupy a large amount of land resources, but the free calcium oxide, magnesium oxide and other components it contains may also react with water and expand, leading to the collapse of the slag pile. At the same time, the heavy metal ions in steel slag also pose a risk of seeping into and polluting the soil and groundwater. Therefore, the resource utilization and harmless treatment of steel slag has become a key link in the green development of the steel industry.

[0003] Hot quenching of steel slag is one of the mainstream steel slag treatment processes. Its core principle is to utilize the residual heat of the steel slag itself (the furnace temperature is usually 800-1200℃) or to introduce saturated steam into the steel slag, so that the free calcium oxide and magnesium oxide in the steel slag react with water to generate stable hydration products (such as calcium hydroxide, calcium silicate hydrate, etc.), thereby stabilizing the steel slag. At the same time, during the hot quenching process, the steel slag will break due to thermal expansion and contraction and hydration reaction, which facilitates the subsequent recycling of scrap steel and processing into building material aggregates (such as road base materials, concrete admixtures, etc.).

[0004] In the hot slag quenching process, the feeding process is the key process connecting the steel slag production and the hot quenching treatment. Its core requirement is to safely, continuously and evenly transport the freshly produced high-temperature steel slag to the inlet of the hot quenching device (such as the hot quenching tank or hot quenching pit). However, the existing steel slag hot quenching feeding methods have obvious shortcomings: (1) The existing feeding methods mostly use cranes to lift the steel slag from the slag tank to the vicinity of the hot quenching device inlet, and then manually push the steel slag into the inlet with shovels or rakes, or use simple feeding devices to transport the steel slag to the vicinity of the inlet, and then manually push the steel slag into the inlet. However, the temperature of the freshly produced steel slag is extremely high (the surface temperature can reach 500-800℃), and it is easy to generate high-temperature dust and splashing small particles. When the manual operation is close, it is very easy to cause safety accidents such as high-temperature burns and dust inhalation. Therefore, we propose a feeding device for steel slag hot quenching processing. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding device for hot slag processing, so as to solve the problem mentioned in the background art that when feeding steel slag, it is necessary for a person to stand near the feeding port of the hot slag device to assist in feeding, and the temperature near the feeding port is high, which can easily cause injury to the worker.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for hot slag processing, comprising a feeding frame, a support leg welded to the bottom of the feeding frame, a pusher plate slidably disposed inside the feeding frame, a rotating sleeve rotatably embedded at one end of the feeding frame, a reciprocating screw through which a reciprocating screw is installed, one end of the reciprocating screw being welded to the surface of the pusher plate, an inner block disposed in the thread groove on the surface of the reciprocating screw, the inner block being welded to the inner wall of the rotating sleeve, a secondary gear welded to the rotating sleeve, the secondary gear being meshed with a main gear, a base welded to the support leg, a motor mounted on the base, the main gear being mounted on the rotating output end of the motor, and a material cylinder welded to the top of one end of the feeding frame.

[0007] Preferably, the longitudinal section of the rotating sleeve is circular, and the cross section of the rotating sleeve is I-shaped.

[0008] Preferably, a rib is welded to the connection between the reciprocating screw and the pusher plate, and the rib has a triangular cross-section.

[0009] Preferably, the end face of the feeding rack is provided with a guide hole, and a guide rod passes through the inside of the guide hole. One end of the guide rod is fixed to the surface of the pusher plate by welding.

[0010] Preferably, there are two guide holes, and the two guide holes are symmetrically arranged about the vertical plane of the feeder.

[0012] Preferably, the inner cavity of the material cylinder has a funnel-shaped structure, and the cross-section of the material cylinder has a rectangular structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

At this time, the motor works, drives the main gear and auxiliary gear to mesh and drive the rotating sleeve to rotate. The rotating sleeve and the inner block cooperate to drive the reciprocating screw to move back and forth along the axis of the rotating sleeve, thereby driving the pusher plate to move back and forth on the feeding frame and push the steel slag that falls into the conveying groove into the hot quenching device. This process does not require manual assistance at the material inlet of the hot quenching device, making the hot quenching of steel slag safer and more reliable. Through the designed rib plate, the rib plate is installed at the connection between the reciprocating screw and the pusher plate to strengthen the connection and prevent cracking, thereby improving the structural connection firmness of this utility model. Through the designed guide hole and guide rod, the guide rod moves synchronously with the pusher plate. The guide rod moves in the guide hole, thereby guiding the pusher plate to avoid tilting and affecting the steel slag feeding effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a feeding device for hot slag processing, including a feeding frame 1, a support leg 8 welded to the bottom of the feeding frame 1, a pusher plate 6 slidably disposed inside the feeding frame 1, a rotating sleeve 10 rotatably embedded at one end of the feeding frame 1, a reciprocating screw 5 throughly installed inside the rotating sleeve 10, one end of the reciprocating screw 5 welded to the surface of the pusher plate 6, an inner block 11 disposed in the thread groove on the surface of the reciprocating screw 5, the inner block 11 welded to the inner wall of the rotating sleeve 10, a secondary gear 12 welded to the rotating sleeve 10, the secondary gear 12 meshing with a main gear 13, a base 3 welded to the support leg 8, a motor 2 mounted on the base 3, the main gear 13 mounted on the rotating output end of the motor 2, a material cylinder 7 welded to the top of one end of the feeding frame 1, and the pusher plate 6 having an L-shaped longitudinal section. The material plate 6 has a rectangular cross-section, and the inner cavity of the material cylinder 7 has a funnel-shaped structure. The material cylinder 7 has a rectangular cross-section. Through the designed feeding frame 1, pusher plate 6, rotating sleeve 10, reciprocating screw 5, motor 2, material cylinder 7, main gear 13, and auxiliary gear 12, the steel slag is fed into the material cylinder 7. It slides into the conveying groove of the feeding frame 1 through the funnel-shaped sliding surface inside the material cylinder 7. At this time, the motor 2 works, driving the main gear 13 and auxiliary gear 12 to mesh and drive the rotating sleeve 10 to rotate. The rotating sleeve 10 and the inner block 11 cooperate to drive the reciprocating screw 5 to move back and forth along the axial direction of the rotating sleeve 10, thereby driving the pusher plate 6 to move back and forth on the feeding frame 1, pushing the steel slag that falls into the conveying groove into the hot quenching device. This process does not require manual assistance at the material inlet of the hot quenching device, making the hot quenching feeding of steel slag safer and more reliable. The longitudinal section of the rotating sleeve 10 is circular, and the cross-section of the rotating sleeve 10 is I-shaped.

[0025] In this embodiment, preferably, a rib plate 9 is welded to the connection between the reciprocating screw 5 and the pusher plate 6. The rib plate 9 is designed and installed at the connection between the reciprocating screw 5 and the pusher plate 6 to reinforce and support the connection, prevent cracking, and improve the structural connection firmness of this utility model. The cross-section of the rib plate 9 is a triangular structure.

[0026] In this embodiment, preferably, the end face of the feeding rack 1 is provided with a guide hole 14, and a guide rod 4 passes through the inside of the guide hole 14. One end of the guide rod 4 is fixed to the surface of the pusher plate 6 by welding. Through the designed guide hole 14 and guide rod 4, the guide rod 4 moves synchronously with the pusher plate 6. The guide rod 4 moves within the guide hole 14, thereby guiding the pusher plate 6 to move and avoid it from tilting and affecting the slag feeding effect. There are two guide holes 14, and the two guide holes 14 are symmetrically arranged about the vertical plane of the feeding rack 1.

[0027] The working principle and usage process of this utility model are as follows: The discharge end of the feeding rack 1 of this utility model is set at the inlet of the hot simmering device. The initial pusher plate 6 of this utility model is located at the bottom of the material cylinder 7 to seal the material inlet of the material cylinder 7. When feeding steel slag, the steel slag is poured into the material cylinder 7. At this time, the motor 2 (model 57BLY70-230) is turned on. The connecting wire of the motor 2 is connected to the equipment, and the power is turned on to make the output shaft of the motor 2 rotate. The motor 2 drives the main gear 13 and the auxiliary gear 12 to mesh and drive the rotating sleeve 10 to rotate. The rotating sleeve 10 and the inner block 11 cooperate to drive the reciprocating screw 5 along the rotating sleeve 10. The axial reciprocating movement drives the pusher plate 6 to reciprocate on the feeding frame 1. When the pusher plate 6 moves back and opens the bottom opening of the material cylinder 7, the steel slag inside the material cylinder 7 falls into the conveying groove of the feeding frame 1. When the pusher plate 6 is pushed forward by the reciprocating screw 5, the pusher plate 6 pushes the steel slag to the outlet of the conveying frame 1 and causes the steel slag to fall into the inlet of the hot simmering device, thus realizing the feeding. In the process of reciprocating pushing the steel slag, when the pusher plate 6 pushes the steel slag, the top part of the pusher plate 6 can block the material opening at the bottom of the material cylinder 7, which can realize the intermittent feeding adjustment of the material cylinder 7, effectively preventing all the steel slag from being poured into the feeding frame 1 at once and affecting the feeding.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
