Description

Technical Field

[0001] The utility model belongs to the technical field of scrap steel recovery, and particularly relates to a scrap steel recovery and screening device. Background Art

[0002] Scrap steel recycling plays an important role. It can save a lot of natural resources, reduce the demand for new ore mining, and reduce energy consumption. Recycling scrap steel helps to reduce environmental pollution, such as reducing carbon emissions and wastewater discharge during mining and smelting. At the same time, scrap steel recycling provides an important source of raw materials for the steel industry and reduces production costs. However, in the current scrap steel recycling field, the inability to effectively screen out the mixed light debris and waste slag has brought many significant disadvantages, which seriously affects the quality of scrap steel. Light debris such as plastics, cloth, etc., as well as the presence of waste slag, reduce the purity and quality of scrap steel. For example, in the steel smelting process, these impurities may cause the composition of molten steel to be unstable, affecting the performance and quality of the final steel, so that the produced steel may have problems such as insufficient strength and poor toughness, and reduce the recycling efficiency. Since a lot of time and energy are needed to screen impurities, the recycling speed of scrap steel is slowed down, affecting the work progress. In order to solve these problems, it is necessary to develop a scrap steel recycling screening equipment. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a scrap steel recovery and screening device, comprising: a screening pool 100, a supporting bottom frame 200 and a screening plate 400, wherein the supporting bottom frame 200 is connected to the bottom of the screening pool 100, a screening plate 400 is arranged above the inside of the screening pool 100, a screening slot 410 is arranged on the upper surface of the screening plate 400, and a plurality of screen holes 500 are arranged through the bottom of the screening slot 410;

[0023] A spring 700 is installed at each of the four corners below the screening plate 400, a pressure frame 800 is connected below the four springs 700, and a hydraulic cylinder 900 is installed on the left and right sides below the pressure frame 800;

[0024] A waste residue drawer 300 is installed in the supporting bottom frame 200 , and the supporting bottom frame 200 is communicated with the inside of the screening pool 100 . A vibration motor 120 is installed in the middle below the screening plate 400 .

[0025] A fixing plate 110 is installed on the left and right sides of the lower interior of the screening tank 100 , and the lower ends of the left and right hydraulic cylinders 900 are connected to the fixing plates 110 , respectively.

[0026] Sealing strips are installed around the waste slag drawer 300, and a handle 600 is installed in the middle of the front of the waste slag drawer 300.

[0027] A drain valve is installed in the middle of the back side of the waste residue drawer 300 , and the drain valve is connected to the inside of the waste residue drawer 300 .

[0028] The four hydraulic cylinders 900 operate synchronously, and the waste slag drawer 300 is slidably connected to the inside of the supporting bottom frame 200 .

[0029] The plurality of groups of sieve holes 500 are equidistantly distributed and are all circular, and the spring 700 is a stainless steel spring.

[0030] See also Figures 1 to 4As the first embodiment of the utility model: the scrap steel to be screened is placed in the screening tank 410, and then the vibration motor 120 is started. The vibration motor 120 can drive the screening plate 400 to vibrate, and the scrap steel in the screening tank 410 is vibrated and screened. The waste slag in the scrap steel falls downward through the multiple groups of sieve holes 500 into the waste slag drawer 300 for centralized collection. When the screening plate 400 vibrates, it can drive the four springs 700 to vibrate. The vibration of the springs 700 can further enhance the vibration effect of the screening plate 400, so that the material is subjected to more vibrations in different directions and intensities on the screening plate 400, which helps to more efficiently separate smaller waste slag from scrap steel, and improve the screening accuracy and efficiency. When the waste slag needs to be removed, the waste slag drawer 300 can be pulled out by the handle 600 to pour out the waste slag inside it.

[0031] See also Figure 1 , Figures 2 to 3 As the second embodiment of the utility model: combined with the further elaboration of the first embodiment, when it is necessary to screen out the light impurities mixed in the scrap steel, water can be added to the screening pool 100 in advance so that it is under the screening plate 400. After the waste slag is screened out, the pressure frame 800 is driven down by the four hydraulic cylinders 900, thereby driving the screening plate 400 to descend into the water. At the same time, the light debris mixed in the scrap steel floats up under the action of the buoyancy of the water, and then the floating debris can be fished out. At the same time, the vibration motor 120 can be started to drive the scrap steel in the screening tank 410 to vibrate, so that the light debris can be quickly floated and separated from the scrap steel. When it is necessary to drain the water, the drain valve can be opened to drain it. Through the above steps, the final effect is that the light debris mixed in the scrap steel can be floated up by the buoyancy of the water, which further improves the purity of the scrap steel, and the light debris is separated by the buoyancy of the water. The method is simple and low in cost, and does not require complex equipment and high energy consumption.
