Description

Technical Field

[0001] The present application relates to the field of wire rod dephosphorization, and in particular to an environmentally friendly double-line through-type wire rod dephosphorization machine. Background Art

[0002] Wire rod, also known as wire, typically refers to the small diameter of the coil. Wire rod diameters range from 5-19 mm (typically 6-9 mm), with the lower limit being the minimum cross-sectional dimension. After production, wire rod is typically stored in coils. One of the primary surface preparation steps before drawing is dephosphorization. This primarily aims to remove the hard and brittle iron oxide scale on the wire rod surface, preventing it from increasing friction and damaging the mold and wire surface during drawing. Current methods for dephosphorization include chemical or electrochemical removal of the scale and physical sandblasting.

[0003] Among them, the physical sandblasting method to remove the iron oxide scale on the surface of the wire rod mainly adopts the dephosphorization machine, which is as follows: a feed port and a discharge port are set at both ends of the dephosphorization machine for passing a single straightened wire rod. Then, the inside of the dephosphorization machine is equipped with multiple directions of throwers around the circumference of the wire rod along the walking path of the wire rod. When the wire rod passes through the inside of the dephosphorization machine, steel sand is thrown onto the surface of the wire rod by the thrower to realize the dephosphorization operation.

[0004] However, there is a big problem with this type of dephosphorization machine. It can only remove phosphorus with a single wire rod. When it is expected to improve the dephosphorization efficiency and use two wire rods to transport them to the dephosphorization machine for dephosphorization, it will be found that both wire rods have poor dephosphorization effects and the circumference of the wire rod cannot completely and effectively remove phosphorus. After detailed research, the main problem is that there is mutual obstruction between the two wire rods, which makes it impossible to achieve a better dephosphorization effect when the two wire rods are performing dephosphorization operations. Summary of the Invention

[0005] In order to effectively realize the dephosphorization operation of double-root wire rods, the present application provides an environmentally friendly double-line through-type wire rod dephosphorization machine.

[0006] This application provides an environmentally friendly double-line wire rod dephosphorization machine, which adopts the following technical solutions:

[0007] An environmentally friendly double-line through-type wire rod dephosphorization machine, comprising:

[0008] Chassis;

[0009] Two wire rod channels pass through the chassis horizontally, the axes of the two wire rod channels are inclined to the horizontal plane, and the horizontal projections and vertical projections of the two wire rod channels do not overlap;

[0010] Four throwers are arranged in the chassis along the extension direction of the two wire rod channels, two of which are located on the upper and lower sides of the two wire rod channels, and the other two are located on the horizontal sides of the wire rod channels. Each of the throwers can throw steel sand toward the two wire rod channels.

[0011] By adopting the above technical solution, the two wire rods are conveyed in the chassis through the two wire rod channels, and a spacing of at least the same as the diameter of the steel grit is maintained between the two wire rods in the horizontal and vertical directions, allowing the steel grit to pass through. At the same time, four throwers are set up in the conveying direction of the two wire rods, surrounding the two wire rods in the upper, lower, left and right directions relative to the two wire rods, and throwing steel grit toward the wire rods, so that the dephosphorization of the entire circumference of the two wire rods can be achieved, avoiding the existence of any position on the circumference of the wire rod that has not been hit by the steel grit, and effectively realizing the dephosphorization operation of the two wire rods.

[0012] Optionally, also include:

[0013] Four dephosphorization chambers are arranged along the extension direction of the two wire rod channels, and each thrower is located in a dephosphorization chamber;

[0014] The partition plate is vertically arranged between adjacent dephosphorization chambers, and guide openings are formed on the partition plate at positions corresponding to the two wire rod channels.

[0015] By adopting the above technical solution, during operation, the wire rod passes through the two guide ports of each partition plate and passes through the four dephosphorization chambers. When the throwers in the four dephosphorization chambers are operating, the steel sand can be effectively ejected in the corresponding dephosphorization chamber, avoiding affecting the operation of other throwers and ensuring the dephosphorization effect of the wire rod.

[0016] Optionally, also include:

[0017] Multiple return troughs are respectively arranged on the lower side of each dephosphorization chamber in the chassis;

[0018] The material accumulation trough is horizontally arranged at the lower side of the multiple return material troughs and is connected to each return material trough;

[0019] The lifter is vertically fixed to the chassis, with its lower end connected to the material trough, and is used to lift the sand and pills in the material trough;

[0020] The sand pill separator is fixed on the upper side of the chassis and is used to receive the sand pills lifted by the lifter, separate the sand pills from the waste chips, and then send the sand pills back to the thrower.

[0021] By adopting the above technical solution, the steel sand in the dephosphorization chamber will fall into each return trough after losing power due to bouncing, and then the steel sand will fall into the accumulation trough for storage. At this time, the lifter can lift the steel sand from the accumulation trough to the sand shot separator, and then the sand shot separator will separate the sand shot from the waste chips, and then put the sand shot back into the thrower to realize the reuse of the steel sand.

[0022] Optionally, an elastic receiving plate is horizontally arranged between the dephosphorization chamber and the return trough;

[0023] The receiving plate is provided with a plurality of blanking holes with a hole diameter not less than the diameter of the steel sand.

[0024] By adopting the above technical solution, the receiving plate can further rebound the steel sand during the steel sand ejection process, and when the steel sand has no power, it can automatically fall through the drop holes into the return trough to realize the recovery of the steel sand.

[0025] Optionally, also include:

[0026] The cleaning chamber is arranged on both sides of the chassis, communicated with the interior of the chassis, and corresponds to the ends of the two wire rod channels;

[0027] A plurality of baffles are arranged along the extension direction of the wire rod channel. A cover is fixed at a position of each baffle corresponding to the wire rod channel. The cover is provided with a cross slot for the wire rod to pass through.

[0028] By adopting the above technical solution, the wire rod can be smoothly introduced into the interior of the chassis, and because the baffle plate with a cross-slot cover cooperates with the cleaning chamber, while the wire rod can enter the interior of the chassis, the cover can prevent steel sand from being ejected to the outside, effectively improving the safety of the equipment.

[0029] Optionally, each baffle is vertically plugged into the cleaning chamber.

[0030] By adopting the above technical solution, when the cover is severely worn and needs to be replaced, the baffle plate can be removed by simply lifting it vertically and then the cover can be replaced.

[0031] Optionally, the lower side of the cleaning chamber is connected to a return trough.

[0032] By adopting the above technical solution, when some steel sand is occasionally ejected into the cleaning chamber, the steel sand will fall due to its own gravity and then fall back into the return trough for recycling and reuse.

[0033] Optionally, a guide frame is fixed to a side of the cleaning chamber facing away from the chassis;

[0034] The guide frame is provided with first guide wheels which are symmetrically rotated on both sides of the horizontal plane corresponding to each wire rod channel;

[0035] The guide frame is provided with second guide wheels symmetrically rotating on both sides of the vertical sides corresponding to each wire rod channel;

[0036] The first guide wheel and the second guide wheel can both abut against the circumferential surface of the wire rod.

[0037] By adopting the above technical solution, the cooperation of the first guide wheel and the second guide wheel can achieve the restriction of the end of the wire rod entering the chassis, thereby achieving the restriction of the conveying position of the wire rod in the chassis, so that the two wire rods are kept in the position of two wire rod channels for conveying, so as to ensure the dephosphorization effect of the wire rod.

[0038] Optional sand and shot separator includes:

[0039] separation chamber;

[0040] The feeding pipe is fixed horizontally on the vertical side of the separation chamber and is used to communicate with the lifter;

[0041] A screw conveyor is coaxially arranged in the feed pipe, and one end of the screw conveyor extends into the separation chamber;

[0042] The diverter cylinder is fixed in the separation chamber and is coaxially sleeved on the outside of the screw conveyor. The diverter cylinder is evenly provided with mesh holes, and the mesh hole diameter is the same as the diameter of the steel grit;

[0043] A material guide plate is fixed in the separation chamber and located on the lower side of the diverter cylinder, and the end of the material guide plate away from the diverter cylinder is tilted downward;

[0044] The sand falling port is provided at the lower end of the guide plate corresponding to the separation chamber, and a debris extraction port is formed between the sand falling port and the lower end of the guide plate;

[0045] The dust extraction component is connected to the separation chamber and is used to extract impurities from the impurity extraction port.

[0046] By adopting the above technical solution, during operation, after the steel sand enters the feed pipe, the spiral feeder transports the steel sand and waste chips to the diversion cylinder in the separation chamber. As the steel sand and waste chips are transported to the diversion cylinder, the steel sand and waste chips can flow down from the mesh holes of the diversion cylinder. Since the aperture of the diversion cylinder allows one steel sand to flow out, the steel sand will flow onto the guide plate in a relatively uniform state in a curtain-like form. Then the steel sand will fall from the exhaust port to the sand dropout port after being buffered and guided by the guide plate. In this process, the dust extraction component can extract the waste chips from the exhaust port. Since the size of the exhaust port is small, the flow rate of the airflow passing through the exhaust port can be increased, and the negative pressure suction force can be increased to ensure complete chip extraction.

[0047] Optionally, the sand and pill separation chamber further includes:

[0048] A diverter plate is vertically and movably arranged at an upper position corresponding to the lower end of the guide plate in the separation chamber, and when the diverter plate is at the lowest position, a material drop gap with a height of the steel grit diameter is formed between the diverter plate and the guide plate;

[0049] The counterweight is fixed to the manifold.

[0050] By adopting the above technical solution, the diverter plate and the counterweight block are set up, which can keep the diverter plate at the lowest position under normal conditions to limit the flow rate of the steel sand and avoid excessive falling of the steel sand. When there is too much steel sand and steel sand blockage occurs, the steel sand can push the diverter plate to rise appropriately to allow the blocked steel sand to flow down from the bottom of the diverter plate to ensure operation.

[0051] In summary, this application includes at least one of the following beneficial technical effects:

[0052] 1. The two wire rods are conveyed in the chassis through two wire rod channels, and a spacing of at least the same as the diameter of the steel grit is maintained between the two wire rods in the horizontal and vertical directions to allow the steel grit to pass through. At the same time, four throwers are set up in the conveying direction of the two wire rods to surround the two wire rods in the upper, lower, left and right directions relative to the two wire rods, and steel grit is thrown toward the wire rods, so that dephosphorization can be achieved with full coverage of the circumference of the two wire rods, avoiding the existence of any position on the circumference of any wire rod that is not hit by the steel grit, and effectively realizing the dephosphorization operation of two wire rods.

[0053] 2. The cooperation of the first guide wheel and the second guide wheel can realize the restriction of the end of the wire rod entering the chassis, thereby limiting the conveying position of the wire rod in the chassis, so that the two wire rods are conveyed in the position of two wire rod channels to ensure the dephosphorization effect of the wire rod.

[0054] 3. During operation, the wire rod passes through the two guide ports of each partition plate and passes through the four dephosphorization chambers. When the throwers in the four dephosphorization chambers are operating, the steel sand can be effectively ejected in the corresponding dephosphorization chamber, avoiding affecting the operation of other throwers and ensuring the dephosphorization effect of the wire rod.

[0063] The following is combined with Figure 1-7 This application is described in further detail.

[0064] The present application discloses an environmentally friendly double-line wire rod dephosphorization machine, which is mainly used to solve the problem that when performing double-wire dephosphorization operations, the two wire rods will block each other, resulting in the inability to achieve an optimal dephosphorization effect when performing the dephosphorization operation. To this end, one embodiment of the present application mainly adopts the following ideas:

[0065] Reference Figure 1 and Figure 2 An environmentally friendly double-line wire rod dephosphorization machine includes a chassis 1. The chassis 1 has a rectangular structure as a whole. The chassis 1 has two wire rod channels formed in the horizontal direction. The wire rod channels are paths for the wire rods to pass through the chassis 1. The two wire rod channels pass through the chassis 1 horizontally. The axes of the two channels are inclined at 45° to the horizontal plane, and the horizontal projections and vertical projections of the two wire rod channels do not overlap. Preferably, the horizontal and vertical spacings of the two wire rod channels are not less than the diameter of the steel grit.

[0066] Reference Figure 2 and Figure 3 Four throwers 2 are arranged in the housing 1 along the extension direction of the two wire rod channels. Two throwers 2 are located on the upper and lower sides of the two wire rod channels, and the other two throwers 2 are located on the horizontal sides of the two wire rod channels. Each thrower 2 can throw steel grit toward the two wire rod channels and cover the two wire rod channels.

[0067] In this way, the two wire rods are conveyed in the chassis 1 along the extension direction of the wire rod channel, and a spacing of at least the same as the diameter of the steel sand is maintained between the two wire rods in the horizontal and vertical directions, allowing the steel sand to pass through, thereby avoiding the two wire rods being blocked by each other in the four directions of up, down, left and right during transportation, and four throwers 2 are set up in the conveying direction of the two wire rods, which are surrounded by the two wire rods in the up, down, left and right directions relative to the two wire rods, and steel sand is thrown toward the wire rods, so that phosphorus removal with full coverage of the circumference of the two wire rods can be achieved, avoiding the existence of any position on the circumference of any wire rod that is not hit by the steel sand, and effectively realizing the phosphorus removal operation of two wire rods.

[0068] In other embodiments of the present application, the structure of the chassis 1 is further illustrated.

[0069] Reference Figure 4 and Figure 5 Four dephosphorization chambers 11 are arranged horizontally in the chassis 1, and partition plates 12 are vertically fixed at positions corresponding to adjacent dephosphorization chambers 11 in the chassis 1. The partition plates 12 separate the adjacent dephosphorization chambers 11 into independent areas, and the positions of the partition plates 12 corresponding to the two wire rod channels are formed with guide openings, which penetrate the partition plates 12 to enable the passage of the wire rods. In order to facilitate the passage of the wire rods and enhance the strength of the guide openings of the partition plates 12, bowl-shaped guide rings 121 are protruded at positions corresponding to the guide openings on both sides of the partition plates 12, and the inner hole of the guide ring 121 is a tapered hole with a smaller aperture close to one end of the partition plate 12, thereby achieving the goal of enabling the passage of the wire rods and increasing the strength of the partition plates 12, thereby avoiding the cracking of the partition plates 12 when the steel sand is thrown.

[0070] Reference Figure 2 and Figure 4 The four throwers 2 are fixed in four dephosphorization chambers 11 respectively. The axis directions of the four throwers 2 are perpendicular to the axis direction of the wire rod channel. A motor is installed in the axis direction of each thrower 2 to drive the rotation of the thrower 2. In order to facilitate the adjustment of the shot blasting force of the thrower 2 and improve the efficiency level, the motor uses a high-efficiency wide motor.

[0071] Reference Figure 2 To ensure complete coverage of the wire rods, the blades 21 of the thrower 2 in this embodiment are constructed as follows: The thickness of the blades 21 on both sides is greater than that in the middle, forming an overall "I" shape. The thinner middle region of the blade 21 serves as the ejection zone, and the width of this ejection zone is projected to cover the same-side projection of the two wire rod channels. This way, once the steel grit enters the thrower 2, the motor drives the thrower 2 to rotate, simultaneously dephosphorizing the two wire rods.

[0072] Reference Figure 4 and Figure 5A return trough 13 is formed on the lower side of each dephosphorization chamber 11, and the return troughs 13 are conical to facilitate the dropping of steel sand. A receiving plate 14 is fixed horizontally between the return trough 13 and the dephosphorization chamber 11. The upper side of the receiving plate 14 can be coated with an elastic coating to make the upper side of the receiving plate 14 elastic. A plurality of drop holes 141 are evenly opened on the receiving plate 14, and the plurality of drop holes 141 all penetrate the receiving plate 14, and the aperture of each drop hole 141 is the same as the aperture of the steel sand. The used receiving plate 14 can further rebound the steel sand during the steel sand ejection process, and when the steel sand has no power, it can automatically fall through the drop holes 141 to the return trough 13 to realize the recovery of the steel sand.

[0073] Reference Figure 1 and Figure 5 A storage trough 15 is horizontally provided on the lower side of the chassis 1 corresponding to the multiple return troughs 13. The upper side of the storage trough 15 is connected to each return trough 13. A screw feeder (not shown in the figure) is installed on the inner edge of the storage trough 15 to transport steel grit to one end of the storage trough 15. A lifter 3 is also vertically fixed to one side of the chassis 1. The lifter 3 can be a bucket elevator or a screw elevator. The lower end of the lifter 3 is connected to the storage trough 15 and is used to lift the steel grit transported by the screw feeder.

[0074] A sand and shot separator 4 is also provided on the upper side of the chassis 1. The sand and shot separator 4 is connected to the upper end of the elevator 3, receives the steel sand lifted by the elevator 3, and separates the steel sand and impurities. The lower end of the sand and shot separator 4 is connected to the chassis 1, and is used to deliver the separated steel sand to each thrower 2 for sand supply.

[0075] In this way, after the steel sand in the dephosphorization chamber 11 loses power due to the bounce, it will fall into each return trough 13 through the drop hole 141 of the receiving plate 14. Then, the steel sand will fall into the accumulation trough 15 for storage from each return trough 13. At this time, the screw feeder transports the sand pills to the direction of the elevator 3, and the elevator 3 can lift the steel sand from the accumulation trough 15 to the sand pill separator 4. The sand pill separator 4 then separates the sand pills from the waste chips and puts the sand pills back into the thrower 2 to realize the utilization of the steel sand.

[0076] In other embodiments of the application, the sand and pellet separator 4 is further illustrated.

[0077] Reference Figure 6 The sand and chip separation chamber 41 includes a separation chamber 41. A feed pipe 42 is horizontally fixed to the upper part of the vertical side of the separation chamber 41. The feed pipe 42 is connected to the upper end of the lifter 3. A screw conveyor 43 is coaxially arranged in the feed pipe 42. One end of the screw conveyor 43 passes through the feed pipe 42 and extends into the separation chamber 41. A diverter cylinder 44 is coaxially fixed to the outer side of the separation chamber 41 corresponding to the screw conveyor 43. The diverter cylinder 44 is evenly provided with a plurality of mesh holes 441. The aperture of the mesh holes 441 is the same as the diameter of the steel grit.

[0078] Reference Figure 6 A material guide plate 45 is fixed to the lower side of the corresponding diverter tube 44 of the separation chamber 41. The material guide plate 45 includes an inclined portion 451 and a horizontal portion 452. The inclined portion 451 is located below the diverter tube 44, and the inclined portion 451 is inclined downward at one end away from the diverter plate 48. The horizontal portion 452 is horizontally fixed to the lower end of the inclined portion 451.

[0079] Reference Figure 6 A sand dropout port 46 is formed at the lower end of the separation chamber 41 corresponding to the horizontal portion 452. This port 46 is connected to the chassis 1. A certain distance is formed between the upper side of the sand dropout port 46 and the lower end of the guide plate 45, which serves as a dust extraction port 461. A dust extraction pipe 411 is provided at the rear side of the separation chamber 41. A dust extraction component, such as a pulse dust collector, is also fixed to the rear side of the chassis 1 and is connected to the dust extraction pipe 411.

[0080] Reference Figure 6 During operation, after the steel sand enters the feed pipe, the screw conveyor 43 transports the steel sand to the diverter cylinder 44 in the separation chamber 41, and then the waste chips and steel sand are discharged at the same time through the mesh 441. Since the aperture of the diverter cylinder 44 only allows one steel sand to flow out at the same time, the steel sand can flow to the guide plate 45 in a curtain form, and then the steel sand is buffered and guided by the guide plate 45 and falls from the exhaust port 461 to the sand dropout port 46. In this process, the dust extraction component can extract the waste chips from the exhaust port 461, and since the size of the exhaust port 461 is small, the flow rate of the airflow passing through the exhaust port 461 can be increased, and the negative pressure suction force is increased to ensure that the waste chips in the steel sand are extracted.

[0081] Reference Figure 6 Furthermore, in order to reduce the flow velocity of the steel sand and improve the flow uniformity of the steel sand, a sand retaining plate 47 is provided on the upper side of the inclined portion 451 of the guide plate 45 in the separation chamber 41. A sand falling gap is formed between the sand retaining plate 47 and the guide plate 45. The distance of the sand falling gap is the same as the diameter of the steel sand, so that the steel sand left from the diversion cylinder 44 can be re-evened.

[0082] Reference Figure 6 A diverter plate 48 is vertically arranged above the horizontal portion 452 of the guide plate 45 corresponding to the separation chamber 41. Both ends of the diverter plate 48 slide vertically in the separation chamber 41. A material drop gap is formed between the diverter plate 48 and the guide plate 45. When the diverter plate 48 falls to the lowermost position, the distance of the material drop gap is the same as the diameter of the steel sand. A counterweight block 481 is also fixed on the side of the diverter plate 48 away from the guide plate 45. The counterweight block 481 cooperates with the diverter plate 48 to keep the diverter plate 48 at the lowermost position under normal circumstances.

[0083] Reference Figure 6In this way, the arrangement of the diverter plate 48 and the counterweight block 481 can keep the diverter plate 48 at the lowest position under normal conditions to limit the flow rate of the steel sand and prevent the steel sand from falling too much. When there is a lot of steel sand and steel sand blockage occurs, the steel sand can push the diverter plate 48 to rise appropriately to allow the blocked steel sand to flow down from the lower side of the diverter plate 48 to ensure operation.

[0084] In other embodiments of the application, a cleaning chamber 5 may be added to both the feed port and the discharge port of the chassis 1 , as described in detail below.

[0085] Reference Figure 1 and Figure 7 The cleaning chamber 5 is a box-shaped structure, fixed to the feed side and the discharge side of the chassis 1, and the two cleaning chambers 5 are connected to the dephosphorization chambers 11 on both sides of the chassis 1. The bottom surface of the cleaning chamber 5 is also tilted downward and fixed to the chassis 1, so that the lower side of the cleaning chamber 5 is connected to the return chute 13.

[0086] Reference Figure 7 A plurality of baffles 51 are arranged in the cleaning chamber 5 along the extension direction of the wire rod passage. The baffles 51 are vertically inserted into the cleaning chamber 5, dividing the cleaning chamber 5 into multiple partitions. A cover 52 is fixed to each baffle 51 at the position corresponding to the wire rod passage by bolts, and a cross slot 521 is formed at the center of each cover 52 to allow the wire rod to pass through.

[0087] By adopting a method that allows the wire rod to smoothly enter the interior of the chassis 1, and because the baffle plate 51 with a cross groove 521 and a cover 52 cooperates with the cleaning chamber 5, while allowing the wire rod to enter the interior of the chassis 1, the cover 52 can prevent the steel sand from being ejected to the outside world. When some steel sand is occasionally ejected into the cleaning chamber 5, the steel sand will also fall due to its own gravity and fall back into the material accumulation trough 15 for recycling and reuse. In addition, when the cover 52 is severely worn and needs to be replaced, it is only necessary to vertically lift the baffle plate 51 to remove the baffle plate 51 and replace the cover 52.

[0088] Reference Figure 7 In order to facilitate the guidance of the wire rods entering and leaving the cleaning chamber 5, a guide frame 6 is fixed to the side of the cleaning chamber 5 away from the chassis 1. The guide frame 6 is symmetrically rotated with first guide wheels 61 on both sides of the horizontal direction corresponding to each wire rod channel, and the guide frame 6 is symmetrically rotated with second guide wheels 62 on both sides of the vertical direction corresponding to each wire rod channel; the circumferential surfaces of the first guide wheel 61 and the second guide wheel 62 are both formed with arc grooves for cooperating with the wire rods and limiting the position of the wire rods.

[0089] In this way, the cooperation of the first guide wheel 61 and the second guide wheel 62 can realize the restriction of the ends of the wire rods entering and leaving the chassis 1, thereby achieving the restriction of the conveying position of the wire rods in the chassis 1, so that the two wire rods are kept in the position of two wire rod channels for conveying, so as to ensure the dephosphorization effect of the wire rods.

[0090] The implementation principle of an environmentally friendly double-line wire rod dephosphorization machine in the embodiment of the present application is as follows:

[0091] The two wire rods are guided by the first guide wheel 61 and the second guide wheel 62 on the feed side of the chassis 1 and enter the cleaning chamber 5, then enter the chassis 1, pass through each dephosphorization chamber 11 in turn, and are output from the cleaning chamber 5 on the discharge side of the chassis 1 and the first guide wheel 61 and the second guide wheel 62 of another guide frame 6.

[0092] When the two wire rods are conveyed in the chassis 1, a spacing of at least the same as the diameter of the steel grit is maintained between the two wire rods in the horizontal and vertical directions, allowing the steel grit to pass through, thereby preventing the two wire rods from being blocked by each other in the four directions of up, down, left and right during transportation. At the same time, the four throwers 2 throw steel grit toward the wire rods in the four directions of up, down, left and right relative to the two wire rods, thereby achieving phosphorus removal with full coverage of the circumference of the two wire rods.

[0093] After the steel sand in the dephosphorization chamber 11 loses power due to the bounce, it will fall into each return trough 13 through the drop hole 141 of the receiving plate 14. Then, the steel sand will fall into the accumulation trough 15 for storage from each return trough 13. At this time, the screw feeder transports the sand pills to the direction of the elevator 3. The elevator 3 can lift the steel sand from the accumulation trough 15 to the sand pill separator 4. The sand pill separator 4 then separates the sand pills from the waste chips and puts the sand pills back into the thrower 2 to realize the utilization of the steel sand.
