Abstract
Description
Technical Field
[0001] This application relates to the field of waste sand processing technology, specifically a waste sand filtration and recycling device. Background Technology
[0002] Sand casting is a casting method that produces castings in sand molds. Steel, iron, and most non-ferrous alloy castings can be obtained using sand casting. To ensure that the molding sand and core sand have sufficient strength to prevent deformation or damage during handling, mold assembly, and pouring of molten metal, a molding sand binder is usually added during casting to bind the loose sand particles together. After use, the molding sand still has some value; therefore, waste sand is generally filtered and recycled to avoid resource waste.
[0003] Currently, existing methods for filtering and recycling waste sand typically involve using a filter screen. After filtering, the residue is usually left on the screen. If not cleaned in time, the accumulation of residue will affect the filtration efficiency of the screen. Therefore, staff need to clean the residue on the screen regularly, which increases manual labor and makes the method less practical. Utility Model Content
[0004] The purpose of this application is to provide a waste sand filtration and recycling device that solves the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This application provides a waste sand filtration and recycling device, including a processing box with one side open. A rotating rod is rotatably connected to the inner side wall of the processing box. A filter plate is fixedly sleeved on the rod wall. A first magnetic block is fixedly installed on the upper end of the filter plate. A second magnetic block is fixedly installed on the inner side wall of one side of the processing box, and the first magnetic block and the second magnetic block are magnetically connected. A vibration motor is fixedly installed on the lower end of the filter plate. A discharge port is opened on one side wall of the processing box. An inclined plate for guiding material is installed on the inner side wall of the processing box. The lower end of the inclined plate is located at the discharge port and is located below the end of the filter plate away from the rotating rod. A feed pipe is fixedly installed on the upper end of the processing box. A blocking component for blocking the lower end of the feed pipe is installed inside the processing box. A reset component for resetting the filter plate after rotation is installed inside the processing box.
[0007] By adopting the above technical solution, waste sand is poured into the processing box in batches through the feed pipe during use. The waste sand falls onto the filter plate, and the vibration motor is started, causing the filter plate to vibrate to filter the waste sand. As batches of waste sand are filtered, more and more residue remains on the filter plate, and the weight on the filter plate increases. When the weight on the filter plate exceeds the magnetic force between the first and second magnetic blocks, the first and second magnetic blocks separate, and the filter plate rotates downward around the rotating rod. When one end of the filter plate touches the inclined plate, the filter plate is tilted, and the residue slides down under the force of gravity and is eventually discharged from the discharge port. After the residue is discharged, the filter plate is reset by the reset component, allowing the first and second magnetic blocks to reconnect. This process is repeated. Through this structure, the residue left on the filter plate can be automatically discharged and cleaned without the need for manual cleaning, reducing labor and improving the applicability of the device.
[0008] Optionally, the shielding assembly includes a drive rod rotatably connected to the inner wall of one side of the processing box, a gear fixedly connected to one end of the drive rod, a rack slidably connected to the top of the processing box, and the gear meshing with the rack. A baffle is fixedly connected to one end of the rack, and the baffle is located at the inlet of the lower end of the feed pipe. The baffle is adapted to the size of the feed pipe. The drive rod and the rotating rod are connected by a belt pulley.
[0009] By adopting the above technical solution, when the rotating rod rotates, it drives the drive rod to rotate via the pulley. The rotation of the drive rod drives the gear to rotate, and the rotation of the gear drives the baffle to move via the rack. The baffle blocks the lower end of the feed pipe, preventing waste sand from continuing to enter the processing box. Through the above structure, the device can automatically block the opening of the feed pipe when discharging residue, preventing excessive unfiltered waste sand from falling onto the filter plate and being discharged with the residue, thereby improving the practicality of the device.
[0010] Optionally, a limiting groove is provided at the inner top of the processing box, a limiting block is slidably connected in the limiting groove, and the lower end of the limiting block is fixedly connected to the rack.
[0011] By adopting the above technical solution, the rack is limited, thereby improving the stability of rack movement.
[0012] Optionally, a limiting rod is fixedly connected to the inner wall of the limiting groove, the limiting rod passes through the limiting block, and the limiting block is slidably connected to the limiting rod.
[0013] By adopting the above technical solution, the limiting block is prevented from detaching from the limiting rod.
[0014] Optionally, the reset assembly includes two fixed pulleys respectively fixedly installed on the top and one side outer wall of the processing box. The upper end of the filter plate is connected to a pull belt, and the other end of the pull belt is wrapped around the two fixed pulleys in sequence and extends outward and is connected to a pull ring. The pull belt passes through the corresponding side wall of the processing box.
[0015] By adopting the above technical solution, pulling the pull ring will cause the pull ring to exert a force on the filter plate through the pull belt and two fixed pulleys. The filter plate will rotate upward around the rotating rod until the first magnetic block and the second magnetic block are in contact.
[0016] Optionally, a partition is connected to the lower end of the filter plate, and the partition abuts against the inclined plate.
[0017] By adopting the above technical solution, the filtered waste sand is prevented from falling onto the inclined plate.
[0018] Optionally, a door may be installed at the opening of the processing box.
[0019] By adopting the above technical solution, the sealing performance of the device is improved.
[0020] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0021] (1) The technical solution of this application can automatically discharge and clean the residue left on the filter plate by setting up a processing box, rotating rod, filter plate, first magnetic block, second magnetic block, vibration motor, discharge port, inclined plate, feed pipe, fixed pulley and pull belt and other structures in cooperation. This eliminates the need for staff to clean it, reduces manual labor, and thus improves the applicability of the device.
[0022] (2) The technical solution of this application can automatically block the opening of the feed pipe when the device discharges residue by setting up the cooperation between the drive rod, gear, rack and baffle, so as to prevent unfiltered waste sand from falling onto the filter plate and being discharged together with the residue, thereby improving the practicality of the device.

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figure 1-5 This application provides a technical solution: a waste sand filtration and recycling device, including a processing box 1 with one side open, a rotating rod 2 rotatably connected to the inner wall of the processing box 1, a filter plate 3 fixedly sleeved on the rod wall of the rotating rod 2, a first magnetic block 4 fixedly installed on the upper end of the filter plate 3, a second magnetic block 5 fixedly installed on the inner wall of one side of the processing box 1, and the first magnetic block 4 and the second magnetic block 5 are magnetically connected, a vibration motor 6 fixedly installed on the lower end of the filter plate 3, a discharge port 7 is opened on one side wall of the processing box 1, an inclined plate 8 for guiding material is installed on the inner wall of the processing box 1, the lower end of the inclined plate 8 is set at the discharge port 7, and the inclined plate 8 is located below the end of the filter plate 3 away from the rotating rod 2, a feed pipe 9 is fixedly installed on the upper end of the processing box 1, a blocking component for blocking the lower end of the feed pipe 9 is installed inside the processing box 1, and a reset component for resetting the filter plate 3 after rotation is installed inside the processing box 1.
[0032] In the technical solution of this application, during use, waste sand is poured into the processing box 1 in batches from the feed pipe 9. The waste sand falls onto the filter plate 3. The vibration motor 6 is started, which causes the filter plate 3 to vibrate, thus filtering the waste sand. As batches of waste sand are filtered, more and more residue remains on the filter plate 3, and the weight on the filter plate 3 increases. When the weight on the filter plate 3 exceeds the magnetic force between the first magnetic block 4 and the second magnetic block 5, the first magnetic block 4 and the second magnetic block 5 separate, and the filter plate 3... The filter plate 3 will rotate downwards around the rotating rod 2. When one end of the filter plate 3 touches the inclined plate 8, the filter plate 3 will be in an inclined state, and the residue will slide down under the force of gravity and eventually be discharged from the discharge port 7. After the residue is discharged, the filter plate 3 will be reset by the reset component, so that the first magnetic block 4 and the second magnetic block 5 will be reconnected. This process is repeated. Through the above structure, the residue left on the filter plate 3 can be automatically discharged and cleaned without the need for manual cleaning, thus reducing manual labor and improving the applicability of the device.
[0033] In the technical solution of this application, the shielding assembly includes a drive rod 10 rotatably connected to the inner wall of one side of the processing box 1. A gear 11 is fixedly connected to one end of the drive rod 10. A rack 12 is slidably connected to the top of the processing box 1, and the gear 11 meshes with the rack 12. A baffle 13 is fixedly connected to one end of the rack 12, and the baffle 13 is located at the lower end of the feed pipe 9. The size of the baffle 13 is adapted to the feed pipe 9. The drive rod 10 and the rotating rod 2 are connected by a belt pulley. When the rotating rod 2 rotates, it will pass through... The pulley drives the drive rod 10 to rotate, which in turn drives the gear 11 to rotate. The rotation of the gear 11 then drives the baffle 13 to move through the rack 12. The baffle 13 then blocks the lower end of the feed pipe 9 to prevent waste sand from continuing to enter the processing box 1. This structure allows the device to automatically block the opening of the feed pipe 9 when discharging residue, preventing excessive unfiltered waste sand from falling onto the filter plate 3 and being discharged with the residue, thereby improving the practicality of the device.
[0034] In the technical solution of this application, a limiting groove is provided at the inner top of the processing box 1, and a limiting block 14 is slidably connected in the limiting groove. The lower end of the limiting block 14 is fixedly connected to the rack 12 to limit the rack 12 and improve the stability of the rack 12 movement.
[0035] In the technical solution of this application, a limiting rod 15 is fixedly connected to the inner wall of the limiting groove. The limiting rod 15 passes through the limiting block 14 and the limiting block 14 is slidably connected to the limiting rod 15 to prevent the limiting block 14 from detaching from the limiting rod 15.
[0036] In the technical solution of this application, the reset assembly includes two fixed pulleys 16 respectively fixedly installed on the top and one side outer wall of the processing box 1. The upper end of the filter plate 3 is connected to a pull belt 17. The other end of the pull belt 17 is wrapped around the two fixed pulleys 16 in sequence and extends outward and is connected to a pull ring. The pull belt 17 is set through the corresponding side wall of the processing box 1. In order to prevent the impact force and overall weight of the filter plate 3 from being too heavy when waste sand enters the filter plate 3, causing the first magnetic block 4 and the second magnetic block 5 to separate immediately, a fixed rod is fixedly installed on the outer wall of the processing box 1 to limit the vertical movement of the pull ring. It is not shown in the figure. The pull ring is sleeved on the fixed rod to limit the pull ring. When the pull ring is pulled, the pull ring will apply a force to the filter plate 3 through the pull belt 17 and the two fixed pulleys 16. The filter plate 3 will rotate upward around the rotating rod 2 until the first magnetic block 4 and the second magnetic block 5 are in contact.
[0037] In the technical solution of this application, a partition 18 is fixedly connected to the lower end of the filter plate 3, and the partition 18 abuts against the inclined plate 8 to prevent the filtered waste sand from falling onto the inclined plate 8.
[0038] In the technical solution of this application, a door 19 is installed at the opening of the processing box 1 to improve the sealing of the device.
[0039] During use, waste sand is poured into the processing box 1 in batches through the feed pipe 9. The waste sand falls onto the filter plate 3. The vibration motor 6 is started, which causes the filter plate 3 to vibrate and filter the waste sand. As batches of waste sand are filtered, more and more residue remains on the filter plate 3, and the weight on the filter plate 3 becomes heavier and heavier. When the weight on the filter plate 3 is greater than the magnetic force between the first magnetic block 4 and the second magnetic block 5, the first magnetic block 4 and the second magnetic block 5 will separate, and the filter plate 3 will rotate downward around the rotating rod 2. When one end of the filter plate 3 touches the inclined plate 8, the filter plate 3 will be in an inclined state, and the residue will slide down under the force of gravity and finally be discharged from the discharge port 7. After the residue is discharged, the pull ring is pulled, and the pull ring will apply a force to the filter plate 3 through the pull belt 17 and the two fixed pulleys 16. The filter plate 3 will rotate upward around the rotating rod 2 under the force until the first magnetic block 4 and the second magnetic block 5 are in contact, and this process is repeated.
