Description

Technical Field

[0001] The utility model relates to the field of waste sand processing equipment, in particular to a transport device for screening waste sand in a foundry. Background Art

[0002] During the casting process, sand materials act as molds when melting metal. As the metal melts and cools, the sand materials absorb heat and undergo physical or chemical changes, eventually forming waste sand. The main components of foundry waste sand include clay, quartz sand, and resin. The recycling of foundry waste sand can reduce environmental pollution, realize resource reuse, and reduce production costs.

[0003] Some vibrating screening machines will be installed next to a belt conveyor to transport the foundry waste sand to the next process for processing. When the foundry waste sand is discharged from the discharge port of the vibrating screening machine, the waste sand moving downward due to its own gravity will collide with the belt conveyor, which may cause the waste sand to splash everywhere, increase the subsequent cleaning and collection steps, and increase labor costs.

[0024] The utility model provides Figure 1-3 The device for screening and transporting waste sand in a foundry shown in the figure comprises a screening machine body 1 and a belt conveyor 2. The screening machine body 1 comprises a screening machine main body 101 and two discharge hoppers 102. The belt conveyor 2 is arranged on one side of the screening machine body 1. A buffer mechanism 3 is provided on the top of the belt conveyor 2. The buffer mechanism 3 is used to reduce the force of the waste sand impacting the belt conveyor 2, thereby preventing the waste sand from splashing around and reducing labor costs.

[0025] The buffer mechanism 3 includes a U-shaped cover 301, which is fixedly connected to the top of the belt conveyor 2. A trapezoidal tube 302 is provided on the top of the U-shaped cover 301, and the trapezoidal tube 302 is fixedly connected to the top of the U-shaped cover 301. A buffer hose 303 is provided on the top of the trapezoidal tube 302, and the buffer hose 303 is fixedly connected to the top of the trapezoidal tube 302. A material-blocking diaphragm 304 is provided on the inner wall of the buffer hose 303. When the waste sand collides with the material-blocking diaphragm 304 and the buffer hose 303, the impact force of the waste sand falling will be buffered, thereby reducing the speed and blocking the waste sand. The top of the material diaphragm 304 is fixedly connected to the inner wall of the buffer hose 303. A clamping assembly 305 is provided on one side of the buffer hose 303. The clamping assembly 305 is used to connect the discharge hopper 102 and the buffer hose 303. An elastic band 306 is provided at the bottom of the clamping assembly 305. The elastic band 306 is fixedly connected to one side of the buffer hose 303. The clamping assembly 305 and the elastic band 306 can connect the discharge hopper 102 and the buffer hose 303 together and ensure that the waste sand enters the buffer hose 303 directly after passing through the discharge hopper 102.

[0026] The clamping assembly 305 consists of a U-shaped plate 3051, a threaded hole, an adjusting bolt 3052 and a movable clamping plate 3053. The U-shaped plate 3051 is fixedly connected to one side of the buffer hose 303, and the elastic band 306 is fixedly connected to the bottom of the U-shaped plate 3051. The threaded hole is opened on one side of the U-shaped plate 3051. The outer wall of the adjusting bolt 3052 is threadedly connected to the inner wall of the threaded hole. One end of the adjusting bolt 3052 is rotatably connected to one side of the movable clamping plate 3053, and the adjusting bolt 3052 rotates clockwise in the threaded hole. The adjusting bolt 3052 will drive the movable splint 3053 gradually away from the threaded hole. The adjusting bolt 3052 rotated counterclockwise in the threaded hole will drive the movable splint 3053 gradually closer to the threaded hole. A limit slot is provided at the bottom of the U-shaped plate 3051. The inner cavity of the limit slot is slidably sleeved with a limit slider 3054. The limit slot and the limit slider 3054 are used to improve the smoothness of the movement of the movable splint 3053. The bottom of the limit slider 3054 is fixedly connected to the top of the movable splint 3053.

[0027] A rectangular hole is provided on one side of the U-shaped cover 301, and an L-shaped support bar 4 is symmetrically fixedly connected to the top of the inner wall of the U-shaped cover 301. A screen frame 5 is provided between the two L-shaped support bars 4, and the L-shaped support bar 4 supports the screen frame 5. The screen frame 5 is used for secondary screening of waste sand. The aperture of the sieve hole on the screen frame 5 is 0.5MM. The outer wall of the screen frame 5 is movably connected to the inner cavity of the rectangular hole. A force ball 6 is fixedly connected to one side of the screen frame 5. The force ball 6 facilitates the staff to apply force to drive the screen frame 5 to move, and the outer wall of the force ball 6 is provided with evenly distributed friction patterns.

[0028] Working principle of this utility model:

[0029] When the belt conveyor 2 is used to transport the waste sand discharged from the screening machine to the next process, the U-shaped plate 3051 and the elastic band 306 are first sleeved on the discharge hopper 102, and then a clockwise steering force is applied to the adjusting bolt 3052. The adjusting bolt 3052 rotates clockwise in the threaded hole, which drives the movable clamping plate 3053 to gradually move away from the threaded hole. When the movable clamping plate 3053 can no longer move, the clamping step of the clamping assembly 305 on the discharge hopper 102 is completed, and then the screening machine switch can be turned on to start The waste sand is screened. The screened waste sand will enter the interior of the buffer hose 303 through the discharge hopper 102 and collide with the blocking diaphragm 304 and the inner wall of the buffer hose 303 to complete the deceleration. Then the waste sand will enter the interior of the U-shaped cover 301 through the trapezoidal tube 302 and undergo a secondary screening step through the screen frame 5. Finally, the waste sand will fall onto the belt conveyor 2 for transportation to the next process, reducing the force of the waste sand impacting the belt conveyor 2, effectively avoiding the waste sand from splashing everywhere, eliminating the need for subsequent cleaning and collection work, and reducing labor costs.
