Description

Technical Field

[0001] The utility model belongs to the technical field of slag discharge in cyclone wells, and particularly relates to a waste slag loading device. Background Art

[0002] In the steel production line, the main function of the vortex well is to remove large particles of impurities in the turbid circulating water. The impurities will eventually settle to the bottom of the well with the rotation of the water flow to form oxidized slag. Generally, the vortex well is equipped with a crane and a grab bucket to grab the slag, and the oxidized slag is placed in the slag pool next to the vortex well. When the slag is full, the grab bucket will load it and take it away for treatment. However, in actual use, it is found that the vortex well grab bucket has to take into account both slag grabbing and loading, and the loading time is long, which seriously affects the slag grabbing efficiency. Utility Model Content

[0003] The utility model aims to provide a waste slag loading device which can store oxidized slag and automatically transport the oxidized slag into a truck bucket.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is a waste slag loading device, including a support frame and a box body.

[0005] The box is fixed on the support frame, and the top of the box is open; one or more screw conveyors are horizontally installed at the bottom of the box; the top of the shaft cylinder of each screw conveyor is open; and a first discharge port is opened at the bottom of the tail end of each screw conveyor; a second discharge port is opened at a position on the bottom of the box corresponding to each first discharge port.

[0006] Preferably, a hydraulic cylinder is provided on the side above the box body away from the second discharge port; a push plate is vertically fixed to one end of the piston rod of the hydraulic cylinder; a discharge platform is fixed to one end of the top of the box body close to the hydraulic cylinder; and the push plate is arranged on the discharge platform.

[0007] Preferably, the box body is in an inverted trapezoidal shape.

[0008] Preferably, a connecting portion is provided between the shaft cylinders of adjacent screw conveyors.

[0009] The utility model provides a waste slag loading device, which has the following advantages compared with the prior art:

[0010] (1) The waste slag is pushed from the unloading platform into the box through the hydraulic cylinder, and then the screw conveyor in the box is used to unload and load the material, which greatly improves the loading efficiency and slag grabbing efficiency, reduces the operation rate of the crane and grab bucket, increases the service life of the equipment, and reduces the labor intensity of personnel;

[0011] (2) Simple design, easy to use and low manufacturing cost; BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 Partial cross-sectional view of the side of the box body; Specific embodiments

[0014] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0015] As Figure 1-2 shown, a device for loading waste residue includes a support frame 1 and a box body 2.

[0016] The box body 2 is fixed on the support frame 1, and the top of the box body 2 is open. The box body 2 can store oxidized slag, and the support frame 1 enables the transport truck to move to the bottom of the box body 2 for convenient unloading. One or more screw conveyors 3 are horizontally installed at the bottom inside the box body 2. When the oxidized slag is poured into the box body 2, the screw conveyors 3 at the bottom inside the box body 2 can transport the oxidized slag in the box body 2. The upper part of the shaft cylinder of each screw conveyor 3 is open, facilitating the oxidized slag to fall onto the screw conveyor shaft of the screw conveyor 3. A first discharge port is opened at the bottom of the tail end of each screw conveyor 3. A second discharge port 21 is opened at the position corresponding to each first discharge port at the bottom of the box body 2. By moving the transport truck below the first discharge port and the second discharge port 21, the oxidized slag conveyed by the screw conveyor 3 falls into the transport truck successively from the first discharge port and the second discharge port 21.

[0017] In this embodiment, a hydraulic cylinder 4 is provided on one side of the box body 2 away from the second discharge port 21. The hydraulic cylinder 4 can be fixed by a fixing frame on one side of the box body 2. One end of the piston rod of the hydraulic cylinder 4 is vertically fixed with a push plate 41. A discharge platform 22 is fixed at one end of the top of the box body 2 close to the hydraulic cylinder 4. Through the discharge platform 22, it is convenient for the grab to place the oxidized slag on the discharge platform 22, avoiding the grab reaching into the box body 2 to pour the slag. The push plate 41 is arranged on the discharge platform 22. The oxidized slag on the discharge platform 22 can be pushed into the box body 2 through the hydraulic cylinder 4 and the push plate 41, reducing labor.

[0018] In this embodiment, the box body 2 is in an inverted trapezoid shape, which is convenient for the oxidized slag falling into the box body 2 to directly fall onto the screw conveyor shaft of the screw conveyor 3, facilitating reducing the number of screw conveyors 3 while increasing the storage space of the box body 2 and reducing costs.

[0019] In this embodiment, a connecting part 31 is arranged between the shaft cylinders of adjacent screw conveyors 3 for connecting the shaft cylinders of two screw conveyors 3 to prevent the oxidized slag from falling between adjacent screw conveyors 3.

[0020] Usage method of the utility model: Use a crane and a grab to grab the oxidized slag in the swirl well and place it on the unloading platform 22. Then, start the hydraulic cylinder 4. The piston rod of the hydraulic cylinder 4 extends, and the push plate 41 pushes the oxidized slag into the box body 2. When the transport truck moves below the discharge port 21, start each screw conveyor 3. The screw conveyor 3 conveys the oxidized slag, and the oxidized slag falls from the discharge port 21 into the hopper of the transport truck.
