Description

Technical Field

[0001] This utility model belongs to the field of buried arc slag screening technology, specifically a buried arc slag screening device. Background Technology

[0002] Submerged arc slag is a refining slag that can bury a high-temperature electric arc during the refining process. Submerged arc slag can improve heating efficiency and reduce erosion of refractory materials. After use, submerged arc slag needs to be screened, mainly to separate out metal particles and other impurities for recycling and reuse. Screening can improve the purity of the slag material, recover useful components, maximize resource utilization, and reduce environmental pollution.

[0003] The utility model patent with patent application publication number 202220120932.X discloses a submerged arc welding slag screening device, including a box body. A vibration mechanism is fixedly connected to the side of the box body. A side opening is provided on the side of the box body, and a side plate is movably installed on the inner surface of the side opening. Before vibration screening, clean water is injected into the box body, so that the dust in the welding slag is adsorbed in the clean water, and other impurities float on the surface of the clean water. After vibration screening for a period of time, clean water is added to the water supply pipe, so that the liquid level in the box body rises to the discharge pipe, thereby discharging the floating slag on the surface of the liquid. Then, the drain hole is opened to allow the sewage in the box body to flow out. In conjunction with continued vibration, the welding slag is effectively screened, and clean and classified welding slag is obtained. This greatly improves the actual screening effect of welding slag and avoids the generation of a large amount of dust during vibration screening, thus improving the quality of the working environment and demonstrating good performance.

[0004] As can be seen from the above patent, there are still shortcomings in the actual use of the submerged arc slag screening device. The most obvious one is that because the particle shape of the submerged arc slag is irregular, the irregular slag particles are easy to get stuck in the mesh of the screen during the screening process, causing the screen to be blocked and affecting the screening efficiency of the submerged arc slag. Therefore, we propose a submerged arc slag screening device. Utility Model Content

[0005] The purpose of this invention is to provide a submerged arc slag screening device to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] This application specifically describes a submerged arc slag screening device, comprising: a housing, a collection box, and a U-shaped plate fixed to the side wall of the housing. The collection box is embedded in the upper end of one side wall of the housing. A screening frame is slidably arranged in the inner cavity of the housing.

A rack that cooperates with the gear is fixedly connected to the other side wall of the inner cavity of the housing. A driving component for driving the reciprocating screw to rotate is provided on the side wall of the housing.

[0008] As a preferred technical solution of this application, two sets of rotating shafts are rotatably connected to both ends of the inner sidewall of the box, and convex blocks are fixedly connected to both ends of the sidewall of the rotating shaft.

[0009] As a preferred technical solution of this application, a connecting rod is fixedly connected to one end of the rotating shaft, and a worm gear is fixedly connected to the side wall of the connecting rod.

[0010] As a preferred technical solution of this application, the inner cavity of the U-shaped plate is rotatably connected to a worm gear, the worm gear meshes with a worm wheel, and a transmission rod is fixedly connected to one end of the worm gear and one end of the reciprocating screw. Synchronous pulleys are fixedly connected to the outer walls of the two sets of transmission rods, and a synchronous belt is provided between the two sets of synchronous pulleys.

[0011] As a preferred technical solution of this application, a dust-collecting fan is embedded in the side wall of the collection box, a storage box is fixedly connected to the bottom of the collection box, a guide groove is opened at the bottom of the collection box, and the inlet of the storage box corresponds to the guide groove.

[0012] As a preferred technical solution of this application, the driving component includes a motor, which is fixedly connected to one side wall of the housing, and the power output end of the motor is fixedly connected to the transmission rod at one end of the reciprocating lead screw.

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

[0014] In the scheme of this application:

[0015] 1. The drive unit drives the transmission rod and reciprocating screw to rotate. The reciprocating screw then drives the threaded block to slide horizontally back and forth within the fixed frame. The movement of the threaded block drives the rotating rod to move horizontally back and forth. Since one end of the rotating rod is equipped with a gear that meshes tightly with the rack, when the rotating rod moves horizontally, the gear rolls on the rack and drives the rotating rod and cleaning brush to rotate in the opposite direction. The rotation and movement of the cleaning brush work together to effectively clean the screening frame, reduce screen blockage, and improve the screening efficiency of buried arc slag.

[0016] 2. By installing a collection box and a dust extraction fan on the housing, the dust inside the housing is drawn into the collection box by the dust extraction fan, and the dust falls into the collection box along the guide channel inside the collection box, thereby reducing the occurrence of dust pollution in the working environment and ensuring the health of operators.

A rotating rod 160 is rotatably connected to one end of the rotating rod 160. The rotating rod 160 drives the gear 162 to roll on the rack 140, and the gear 162 drives the rotating rod 160 to rotate in the opposite direction. A cleaning brush 161 is fixedly connected to the outer wall of the rotating rod 160. The rotating rod 160 drives the cleaning brush 161 to move and rotate, thereby cleaning the screening frame 110. A gear 162 is fixedly connected to one end of the side wall of the rotating rod 160. Specifically, a slider is rotatably provided at one end of the rotating rod 160. The rotating rod 160 is slidably set with the box 100 through the slider. A rack 140 that works with the gear 162 is fixedly connected to the other side wall of the inner cavity of the box 100. A drive component for driving the reciprocating screw 151 to rotate is provided on the side wall of the box 100.

[0026] Please see Figure 2-4 Two sets of rotating shafts 120 are rotatably connected to both ends of the inner side wall of the box 100. Protruding blocks 121 are fixedly connected to both ends of the side wall of the rotating shaft 120. The rotating shaft 120 drives the protruding blocks 121 to rotate. The positions of the two sets of protruding blocks 121 are perpendicular to each other, so that the protruding blocks 121 can repeatedly contact the screening frame 110 when rotating, thereby shaking the screening frame 110. Specifically, the top of the box 100 is provided with a detachable top cover, so that the impurities on the screening frame 110 can be cleaned after screening.

[0027] Please see Figure 2-4 A connecting rod 130 is fixedly connected to one end of the rotating shaft 120, and a worm gear 131 is fixedly connected to the side wall of the connecting rod 130. The worm gear 131 drives the connecting rod 130 and the rotating shaft 120 to rotate.

[0028] Please see Figure 2-4A worm gear 310 is rotatably connected to the inner cavity of the U-shaped plate 300. The worm gear 310 meshes with the worm wheel 131. One end of the worm gear 310 and one end of the reciprocating screw 151 are both fixedly connected to a transmission rod 320. Synchronous pulleys 330 are fixedly connected to the outer walls of the two sets of transmission rods 320. A synchronous belt is provided between the two sets of synchronous pulleys 330. The worm gear 310 can drive the worm wheel 131 and the connecting rod 130 to rotate. By setting the transmission rods 320 with a linkage structure, when one set of transmission rods 320 rotates, it can drive the worm gear 310 to rotate synchronously through the synchronous pulleys 330 and the synchronous belt.

[0029] Please see Figure 2 The side wall of the collection box 200 is inlaid with a dust suction fan 210, and the bottom of the collection box 200 is fixedly connected to a storage box 220. The bottom of the collection box 200 is provided with a guide channel, and the inlet of the storage box 220 corresponds to the guide channel.

[0031] Specifically, when using this device, first connect the power supply to the submerged arc slag screening device and add the submerged arc slag into the housing 100. At this time, the submerged arc slag falls onto the screening frame 110. Then, start the motor 170, which drives a set of transmission rods 320 to rotate. The set of transmission rods 320 drives another set of transmission rods 320 and worm gear 310 to rotate through the synchronous pulley 330 and synchronous belt. The worm gear 310 drives the worm wheel 131 and connecting rod 130 to rotate. The connecting rod 130 drives the rotating shaft 120 and the convex block 121 to rotate. Repeated contact with the screening frame 110 achieves horizontal screening. Simultaneously, a set of transmission rods 320 drives the reciprocating screw 151 to rotate. The reciprocating screw 151 drives the threaded block 152 and the rotating rod 160 to move horizontally. At this time, the rotating rod 160 drives the gear 162 to roll on the rack 140. The gear 162 drives the rotating rod 160 and the cleaning brush 161 to rotate in the opposite direction. The cleaning brush 161 cleans the screening frame 110. Finally, by opening the top cover, the impurities inside the screening frame 110 are collected, thus completing the use of the device.
