DETAILED DESCRIPTION
[0029] In order to make the technical problems, technical solutions and beneficial effects of the present application more clear and clear, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.
[0030] As Figures 1-3As shown, a steel grit screening device includes a frame 1 arranged on the ground, and a first mounting plate 2 arranged on the frame 1, the first mounting plate 2 is provided with a mounting rack 3, and a first screening channel 7 is formed between the mounting rack 3 and the first mounting plate 2. A plurality of mounting grooves 4 are arranged and spaced apart on both sides of the mounting rack 3. The screening plate 5 is provided with a protrusion 6 on both sides, and the protrusion 6 is arranged in the mounting groove 4. A plurality of screening plates 5 form a second screening channel 8, and the screening plate 5 is provided with a screen hole. The first screening channel 7 is communicated with the second screening channel 8 through the screen hole. The first screening channel 7 has a first discharge port 9, and the second screening channel 8 has a second discharge port 10.
[0031] In this embodiment, the device includes a frame 1 stably arranged on the ground for supporting the entire screening device. The frame 1 is provided with a first mounting plate 2, and the first mounting plate 2 is fixed with a mounting rack 3. A first screening channel 7 is formed between the mounting rack 3 and the first mounting plate 2 for further screening of steel grit with smaller particle size.
[0032] A plurality of mounting grooves 4 are arranged and spaced apart on both sides of the mounting rack 3, which are used to fix the screening plate 5. The screening plate 5 is provided with a protrusion 6 on both sides, which can be accurately embedded in the mounting groove 4 to ensure that the screening plate 5 is firmly installed on the mounting rack 3. A plurality of screening plates 5 are arranged in parallel to form a second screening channel 8 for preliminary screening of steel grit with larger particle size. The screening plate 5 is uniformly distributed with screen holes, and the first screening channel 7 is communicated with the second screening channel 8 through the screen holes, so that the steel grit can flow between the two channels and complete the screening.
[0033] The end of the first screening channel 7 is provided with a first discharge port 9 for discharging steel grit with smaller particle size, and the end of the second screening channel 8 is provided with a second discharge port 10 for discharging steel grit with larger particle size. Through this design, the steel grit can be effectively separated according to the particle size to meet different production needs.
[0034] The device can simultaneously screen steel grit with different particle sizes by arranging the first screening channel 7 and the second screening channel 8, which improves the screening efficiency and reduces the screening time. The screening plate 5 is installed on the mounting rack 3 through the cooperation of the protrusion 6 and the mounting groove 4, and different aperture screening plates 5 can be replaced according to needs, so as to flexibly adjust the screening precision and adapt to different particle size screening requirements. The overall structure of the device is compact, occupies small space, and is convenient to install and operate, which is suitable for use in limited production space. The installation and disassembly of the screening plate 5 are convenient, which is convenient for cleaning and replacement, reduces the maintenance cost, and prolongs the service life of the equipment.
[0035] Further, a plurality of elastic members 11 are arranged between the mounting frame 3 and the first mounting plate 2, and the elastic members 11 are used to provide a force for the mounting frame 3 to move away from the first mounting plate 2.
[0036] The mounting frame 3 is further provided with a vibration motor 12.
[0037] In this embodiment, the steel scrap screening device is further optimized on the basis of the original structure to improve the screening efficiency and effect. A plurality of elastic members 11 (such as springs) are arranged between the mounting frame 3 and the first mounting plate 2. These elastic members 11 are uniformly distributed at the connecting parts between the mounting frame 3 and the first mounting plate 2, and can provide an elastic force for the mounting frame 3 to move away from the first mounting plate 2. When the device is running, the elastic effect of the elastic members 11 enables the mounting frame 3 to maintain a certain elastic movement during the vibration process, thereby enhancing the screening effect and effectively reducing the blocking phenomenon of the steel scrap at the sieve hole.
[0038] In addition, a vibration motor 12 is also installed on the mounting frame 3. The vibration motor 12 is fixed on the outside of the mounting frame 3 by bolts, and its output end is connected with the mounting frame 3. When the vibration motor 12 is started, it can generate periodic vibration to drive the mounting frame 3 and the screening plate 5 to vibrate together. This vibration effect not only accelerates the flow of steel scrap in the screening channel, but also enables the steel scrap to pass through the sieve hole better, thereby further improving the screening efficiency and precision.
[0039] In actual use, the cooperative action of the elastic members 11 and the vibration motor 12 enables the steel scrap screening device to complete the screening task more efficiently. By adjusting the vibration frequency of the vibration motor 12 and the elastic coefficient of the elastic members 11, the screening effect can be further optimized to meet the screening needs of steel scrap of different particle sizes.
[0040] Further, the mounting frame 3 is further provided with a hinged plate 13 at the mounting groove 4. The hinged plate 13 is hingedly arranged on the mounting frame 3. After the hinged plate 13 swings on the mounting frame 3, it abuts or does not abut the protrusion 6. The hinged plate 13 is further provided with a plurality of threaded holes 14. After the hinged plate 13 abuts the protrusion 6, it is fixed on the mounting frame 3 by bolts passing through the threaded holes 14.
[0041] In this embodiment, the mounting frame 3 is provided with a hinged plate 13 at the mounting groove 4. The hinged plate 13 is mounted on the mounting frame 3 through a hinge structure and can freely swing around the hinge point. When the protrusion 6 of the screening plate 5 is inserted into the mounting groove 4, the hinged plate 13 can be swung to abut against the protrusion 6 to preliminarily position the screening plate 5. If it is necessary to disassemble or adjust the screening plate 5, the hinged plate 13 can be swung to a position not abutting against the protrusion 6 for convenient operation. In addition, the hinged plate 13 is also provided with a plurality of threaded holes 14. After the hinged plate 13 abuts against the protrusion 6, the hinged plate 13 can be fixed on the mounting frame 3 through bolts passing through the threaded holes 14, so as to firmly lock the screening plate 5 and ensure its stability and reliability during screening. This design not only makes the installation and disassembly of the screening plate 5 more convenient, but also enhances the stability of the equipment during operation, and facilitates the maintenance personnel to quickly replace or clean the screening plate 5, thereby effectively improving the operation efficiency and service life of the equipment.
[0042] Further, the first discharge port 9 and the second discharge port 10 are each provided with a guide plate 15, and the guide plates 15 at the first discharge port 9 and the second discharge port 10 are opposite in the direction of guiding the material.
[0043] In this embodiment, at the first discharge port 9, the guide plate 15 is installed below the discharge port, and the inclination direction of the guide plate 15 enables the steel chips with smaller particle size to smoothly slide along the guide plate 15 into the designated collection container. At the second discharge port 10, the inclination direction of the guide plate 15 is opposite to that of the guide plate 15 at the first discharge port 9, so that the steel chips with larger particle size can slide along the guide plate 15 into another designated collection container. This symmetrical and opposite guide design can effectively guide the steel chips of different particle sizes to be discharged separately, avoiding the accumulation or confusion of the material at the discharge port, and improving the screening efficiency and the convenience of material management. The steel chip screening device not only can efficiently separate steel chips of different particle sizes, but also can ensure that the screened material can be accurately and smoothly discharged, further improving the overall performance and practicality of the equipment.
[0044] Further, an upper feeding channel 16 is arranged on the mounting frame 3, and the upper feeding channel 16 is arranged obliquely.
[0045] In this embodiment, the upper feeding channel 16 is fixedly installed above the mounting frame 3, and one end of the upper feeding channel 16 is connected with the inlet of the second screening channel 8, and the other end of the upper feeding channel 16 extends upwardly and obliquely, forming a slope-shaped channel. The obliquely arranged upper feeding channel 16 can utilize the action of gravity to make the steel chips more smoothly slide into the second screening channel 8 when entering the screening device, reducing the possibility of material accumulation and blockage.
[0046] Further, the upper feeding channel 16 is provided with a weir plate 17.
[0047] In the embodiment, the feeding channel 16 is obliquely arranged on the mounting frame 3, with one end connected to the inlet of the second screening channel 8 and the other end extending upward. In order to more effectively control the flow speed and distribution uniformity of the steel chips in the feeding channel 16, a weir plate 17 is arranged on the feeding channel 16. The weir plate 17 is vertically arranged on the inner side wall of the feeding channel 16, and the weir plate 17 functions to form a certain resistance, so that the steel chips form a uniform material layer in the feeding channel 16, preventing the material from being concentrated and unevenly distributed when entering the screening channel. Through the resistance of the weir plate 17, the steel chips can more stably slide to the second screening channel 8, thereby improving the screening efficiency and accuracy.
[0048] Further, the mounting groove 4 and the hinged plate 13 are both provided with elastic blocks 18, which are respectively arranged at both ends of the protrusion 6.
[0049] In the embodiment, the mounting groove 4 and the hinged plate 13 are both provided with elastic blocks 18. The elastic blocks 18 are made of materials with certain elasticity (such as rubber or polyurethane) and are respectively arranged on the inner side of the mounting groove 4 and the contact surface of the hinged plate 13. When the protrusion 6 of the screening plate 5 is embedded in the mounting groove 4, the elastic blocks 18 in the mounting groove 4 can tightly abut against both ends of the protrusion 6, thereby playing a buffering and fixing role. At the same time, the elastic blocks 18 on the hinged plate 13 can also provide additional elastic support when abutting against the protrusion 6, further enhancing the stability of the screening plate 5.
[0050] Further, the elastic force direction of the elastic member 11 is perpendicular to the ground.
[0051] In the embodiment, the elastic member 11 of the steel chip screening device is further optimized in design to ensure that its elastic force direction is perpendicular to the ground, thereby improving the stability and efficiency of the screening process. The elastic member 11 (such as a spring) is installed between the mounting frame 3 and the first mounting plate 2, and its elastic force direction is accurately set to be perpendicular to the ground. This design enables the elastic member 11 to provide an upward supporting force for the mounting frame 3, ensuring that the mounting frame 3 always maintains a vertical relationship with the first mounting plate 2 during vibration. When the vibration motor 12 is started and drives the mounting frame 3 to vibrate, the vertical elastic force of the elastic member 11 can effectively buffer the impact caused by vibration, while maintaining the horizontal stability of the screening plate 5, preventing the screening plate 5 from tilting or shaking due to vibration.
[0052] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
