Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel shot recycling and screening technology, specifically a steel shot recycling and screening device for steel structure workshops. Background Technology
[0002] During the steel structure production process, steel shot rust removal machines are needed to remove rust from the steel structure. After the steel shot has been rust removed, it needs to be screened and recycled by a recycling and screening device so that the steel shot can be reused.
[0003] Existing steel shot recycling screening devices typically use an impact structure on the screen to break up the rust powder accumulated on the screen, allowing the powder to pass through. However, the screen has high processing costs and is prone to malfunction. Furthermore, in existing screening devices, iron dust cannot be effectively separated and processed by the dust collector, affecting the dust removal effect. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a steel shot recycling and screening device for steel structure workshops. By setting up a screen frame, blocking rod, screen mesh and rubber balls, when the screen mesh vibrates under the drive of a vibrating motor, the rubber balls are also vibrated and bounced up. The continuously bouncing and falling rubber balls can impact the screen mesh, thereby dispersing the rust powder accumulated on the screen mesh and letting it fall off the screen mesh, reducing processing costs, avoiding malfunctions, and effectively solving the problems in the background technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel shot recycling and screening device for steel structure workshops, comprising a screening box, wherein three layers of screens are arranged inside the screening box, a screen frame is installed on the lower side of the screens, a blocking rod is horizontally installed on the lower side of the screen frame, and a rubber ball is arranged in the space separated by the blocking rod inside the screen frame, an exhaust pipe is connected to the upper side of the screening box, the exhaust pipe is connected to a dust collection box, an electromagnet plate is installed on the top side inside the dust collection box, and an electric push rod is hinged to the lower side of the electromagnet plate.
[0006] Furthermore, a dust filter bag is installed on the lower side of the first electric push rod, and a centrifugal fan is installed on the outer side of the dust collection box corresponding to the position of the dust filter bag. Centrifugal fan blades are installed at the output end of the centrifugal fan.
[0007] Furthermore, a baffle is slidably connected to the lower part of the dust collector, a second electric push rod is installed on one side of the baffle, and an air outlet pipe is installed on the lower side of the centrifugal fan blade shell.
[0008] Furthermore, two vibrating motors are installed on the lower side of the screening box, and springs are connected to the outside of the screening box via angle irons, with a support frame connected to the lower side of the springs.
[0009] Furthermore, three discharge pipes are installed on the lower side of one end of the screening box, a feed pipe is installed on the upper side of the other end of the screening box, and a discharge inclined plate is installed on the bottom side of the inner side of the screening box.
[0010] Furthermore, the lower end of the spring is sleeved on the support frame, and the distance between the upper and lower layers of the screen is 10mm.
[0011] Furthermore, the height of the blocking rod and the screen frame is 40mm.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, through the setting of a screen frame, blocking rod, screen mesh and rubber balls, makes the rubber balls vibrate and bounce when the screen mesh vibrates under the drive of the vibrating motor. The continuously bouncing and falling rubber balls can impact the screen mesh, thereby dispersing the rust powder accumulated on the screen mesh and letting it fall off the screen mesh, reducing processing costs and avoiding malfunctions.
[0014] 2. This utility model, through the setting of a dust collection box, an electromagnet plate, and a first electric push rod, enables the electromagnet plate to generate a large magnetic field force, thereby adsorbing the iron powder in the dust onto the electromagnet plate. When separation is required, the electromagnet plate is de-energized, and the first electric push rod pushes the electromagnet plate to rotate rapidly, thereby shaking off and collecting the iron powder.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0020] Please see Figure 1-3 This embodiment provides a technical solution: a steel shot recycling and screening device for steel structure workshops, including a screening box 1, with three layers of screens 10 arranged inside the screening box 1, a screen frame 21 installed on the lower side of the screens 10, a blocking rod 19 installed horizontally on the lower side of the screen frame 21, and a rubber ball 20 arranged in the space separated by the blocking rod 19 inside the screen frame 21, an exhaust pipe 7 connected to the upper side of the screening box 1, the exhaust pipe 7 connected to a dust collection box 6, an electromagnet plate 12 installed on the top side inside the dust collection box 6, and an electric push rod 17 hinged to the lower side of the electromagnet plate 12.
[0021] like Figure 1-3 As shown, the steel shot to be screened and recycled is poured into the screen 10 through the feed pipe 5. The vibrating motor 9 drives the screening box 1 to vibrate rapidly. When the two vibrating motors 9 operate in opposite directions, the eccentric centrifugal forces generated partially cancel each other out, and the remaining force combines into a forward excitation thrust. This thrust is transmitted at approximately a 35-degree angle to the screen 10 inside the screening box 1 via the force guiding system, forcing the steel shot to make a jumping motion forward and upward, thus completing the screening. Smaller diameter steel shot falls downwards in sequence, and the rust in the steel shot finally falls onto the discharge inclined plate 11. When the rubber ball 20 bounces up and down, it can vibrate and clean the screen 10, preventing rust from forming on the screen 10. Dust accumulates and clogs the mesh of screen 10, ensuring screening efficiency. When the dust generated during screening floats in the screening box 1, the centrifugal fan 8 drives the centrifugal fan blade 15 to rotate rapidly, thereby creating a negative pressure inside the screening box 1. This allows the dust to enter the dust collection box 6 through the exhaust pipe 7. When the electromagnet plate 12 is energized, it generates magnetic force, thereby adsorbing and fixing the iron dust. When cleaning is required, the electromagnet plate 12 is de-energized, and the first electric push rod 17 drives the electromagnet plate 12 to swing rapidly, thereby shaking the iron dust to the bottom of the dust collection box 6 for easy collection. The second electric push rod 18 drives the baffle 16 to move, thereby opening the bottom of the dust collection box 6, making it easier to clean and collect the collected dust.
[0022] A dust filter bag 13 is installed on the lower side of the No. 1 electric push rod 17. A centrifugal fan 8 is installed on the outer side of the dust collection box 6 corresponding to the position of the dust filter bag 13. Centrifugal fan blades 15 are installed at the output end of the centrifugal fan 8.
[0023] A baffle 16 is slidably connected to the lower part of the dust collector 6. A second electric push rod 18 is installed on one side of the baffle 16. An air outlet duct 14 is installed on the lower side of the casing of the centrifugal fan blade 15.
[0024] Two vibrating motors 9 are installed on the lower side of the screening box 1. Springs 3 are connected to the outside of the screening box 1 by angle iron, and a support frame 2 is connected to the lower side of the springs 3.
[0025] Three discharge pipes 4 are installed on the lower side of one end of the screening box 1, and a feed pipe 5 is installed on the upper side of the other end of the screening box 1. A discharge inclined plate 11 is installed on the bottom side of the inner side of the screening box 1.
[0026] The lower end of the spring 3 is sleeved on the support frame 2, and the distance between the upper and lower layers of the screen 10 is 10mm.
[0027] The height of the blocking rod 19 and the screen frame 21 is 40mm.
[0028] The working principle of the steel shot recycling and screening device for steel structure workshops provided by this utility model is as follows: Figures 1-3 As shown, the steel shot to be screened and recycled is poured into the screen 10 through the feed pipe 5. The vibrating motor 9 drives the screening box 1 to vibrate rapidly. When the two vibrating motors 9 operate in opposite directions, the eccentric centrifugal forces generated partially cancel each other out, and the remaining force combines into a forward excitation thrust. This thrust is transmitted at approximately a 35-degree angle to the screen 10 inside the screening box 1 via the force guiding system, forcing the steel shot to make a jumping motion forward and upward, thus completing the screening. Smaller diameter steel shot falls downwards in sequence, and the rust in the steel shot finally falls onto the discharge inclined plate 11. When the rubber ball 20 bounces up and down, it can vibrate and clean the screen 10, preventing rust from forming on the screen 10. Dust accumulates and clogs the mesh of screen 10, ensuring screening efficiency. When the dust generated during screening floats in the screening box 1, the centrifugal fan 8 drives the centrifugal fan blade 15 to rotate rapidly, thereby creating a negative pressure inside the screening box 1. This allows the dust to enter the dust collection box 6 through the exhaust pipe 7. When the electromagnet plate 12 is energized, it generates magnetic force, thereby adsorbing and fixing the iron dust. When cleaning is required, the electromagnet plate 12 is de-energized, and the first electric push rod 17 drives the electromagnet plate 12 to swing rapidly, thereby shaking the iron dust to the bottom of the dust collection box 6 for easy collection. The second electric push rod 18 drives the baffle 16 to move, thereby opening the bottom of the dust collection box 6, making it easier to clean and collect the collected dust.
