Description

Technical Field

[0001] The utility model belongs to the technical field of iron concentrate production, and particularly relates to an environment-friendly filter for iron concentrate production. Background Technique

[0002] Iron concentrate is the main raw material for pellets and is the ore powder processed from iron ore through crushing, grinding, ore dressing, etc. The fluctuation of the iron content will directly affect the quality of the finished pellet ore.

[0003] For example, the Chinese patent with the publication number CN219899035U discloses an environment-friendly filter for iron concentrate production, which includes a box body. A material box, a blanking box and a support plate are respectively fixedly installed on the top of the box body. The support plates are respectively located on one side of the material box and the blanking box, and the bottom end of the material box is fixedly connected to the top of the blanking box; One side of the support plate is slidably clamped through a connecting rod, and one end of the connecting rod is fixedly connected to a first spring. Through the arranged power assembly, a toothed plate, a connecting rod, a pushing block, a blanking box and a first spring, the power assembly contacts the toothed plate, and the toothed plate drives the connecting rod to move to the right. The connecting rod drives the pushing block to push the iron concentrate inside the blanking box into the filtering box. During the iron concentrate filtering process, the box body is in a sealed state to avoid generating dust and polluting the environment, achieving an environmental protection effect. After the power assembly disengages from the toothed plate, the first spring resets the connecting rod and the pushing block, and the iron concentrate inside the material box falls into the blanking box, thereby achieving the effect of intermittent blanking.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use. For example, when filtering iron concentrate, only a single filter plate is used to filter the iron concentrate, resulting in poor filtering effect. There will still be small impurities in the filtered iron concentrate, making the purity of the filtered iron concentrate not high enough. In view of this, we propose an environment-friendly filter for iron concentrate production. Content of the Utility Model

[0006] The purpose of the utility model is to provide an environment-friendly filter for iron concentrate production to solve the problems put forward in the above background technique.

[0007] In view of this, the utility model provides an environment-friendly filter for iron concentrate production, including:

[0008] A filtering barrel, rectangular grooves are symmetrically opened at the top of the filtering barrel, clamping plates are slidably installed in the rectangular grooves, rotating plates are rotatably installed at the tops of the clamping plates, a same frame is arranged between the two clamping plates, and the frame is located below the two rotating plates. A threaded rod is installed on the rotating plate in a threaded manner, and the bottom end of the threaded rod is rotatably installed with a lower pressing plate that contacts the top of the frame;

[0009] The second filter hopper is fixedly installed at the bottom of the frame and is located inside the filter barrel. A placement groove is formed at the top of the frame. The first filter hopper is placed in the placement groove, and the first filter hopper is located inside the second filter hopper. One side of the filter barrel is fixedly installed with a discharge pipe, and one end of the discharge pipe is communicated with the bottom of the inner cavity of the filter barrel;

[0010] The limiting component is located on the frame and is used for limiting the first filter hopper;

[0011] The power component is located inside the filter barrel and is used for driving the two clamping plates to move up and down.

[0012] In this technical solution, by setting the power component and driving the power component, the power component will drive the two clamping plates and the two rotating plates to move up and down reciprocally. The up and down reciprocating movement of the two clamping plates and the two rotating plates will drive the frame to move up and down reciprocally. The frame will drive the second filter hopper and the first filter hopper to move up and down reciprocally. Subsequently, the person can put the iron ore concentrate that needs to be filtered into the first filter hopper. The up and down reciprocating movement of the first filter hopper can screen the iron ore concentrate, and all the larger impurities contained in the iron ore concentrate can be filtered out. The filtered iron ore concentrate will fall into the second filter hopper, and the impurities will remain in the first filter hopper. Subsequently, under the action of the up and down reciprocating movement of the second filter hopper, the iron ore concentrate in the second filter hopper can be filtered again, and the smaller impurities contained in the iron ore concentrate can be filtered out. Subsequently, the filtered iron ore concentrate will fall to the bottom of the inner cavity of the filter barrel and then be discharged from the discharge pipe, which is convenient for the person to collect, ensuring that the iron ore concentrate can be filtered twice and ensuring that the filtered iron ore concentrate does not contain smaller impurities, so that the filtered iron ore concentrate has a higher purity;

[0013] By setting the limiting component, the limiting component can release the limit on the first filter hopper. The person can take out the first filter hopper from the placement groove through the two handles and clean the impurities in the first filter hopper. Subsequently, the person can rotate the two threaded rods respectively. Under the action of the thread, the rotation of the threaded rod will move upward, and at the same time, the upward movement of the threaded rod will drive the lower pressing plate to move upward until the bottom of the lower pressing plate is far away from the top of the frame. At this time, the person can rotate the rotating plate until the rotating plate rotates 180° on the clamping plate. At this time, the person can remove the frame and the second filter hopper from the two clamping plates and clean the impurities in the second filter hopper, ensuring that it is convenient for the person to clean the impurities in the first filter hopper and the second filter hopper.

[0014] In the above technical solution, further, the limiting component includes:

[0015] A sliding groove is provided. The sliding groove is formed in the frame and is located on one side of the first filter hopper. A limiting block is slidably installed in the sliding groove. One end of the limiting block extends to the top of the first filter hopper. A spring fixed to the limiting block is fixedly installed on the inner wall of the sliding groove.

[0016] In this technical solution, when the limiting block is moved, the limiting block moves in the sliding groove and compresses the spring to contract. When one end of the limiting block moves out of the top of the first filter hopper, the limiting block can release the limit on the first filter hopper at this time. Personnel can take out the first filter hopper from the placement groove through two handles and clean the impurities in the first filter hopper.

[0017] In the above technical solution, further, one end of the limiting block is of an inclined structure, and both ends of the spring are tightly welded to the limiting block and the inner wall of the sliding groove respectively.

[0018] In this technical solution, when the first filter hopper is ensured to be placed in the placement groove, the first filter hopper will squeeze one end of the limiting block to move, ensuring the structural stability of the spring.

[0019] In the above technical solution, further, the power assembly includes:

[0020] Two movable grooves. Both of the movable grooves are formed in the filter barrel and are respectively located on both sides of the second filter hopper. A disc is rotatably installed in the movable groove. A connecting rod is rotatably installed at a position on one side of the disc and away from its center. A sliding rod is rotatably installed on one side of the connecting rod. The top end of the sliding rod penetrates through the top of the movable groove and extends into the corresponding rectangular groove and is fixed to the clamping plate.

[0021] A double-shaft motor is fixedly installed in the filter barrel and is located below the second filter hopper. Two output ends of the double-shaft motor respectively extend into the two movable grooves and are coaxially connected to the corresponding discs.

[0022] In this technical solution, when the dual-axis motor is started, the two output shafts of the dual-axis motor will drive two discs to rotate respectively. The rotation of the discs will drive one end of the connecting rod to rotate. At the same time, one end of the connecting rod will rotate on the disc. The other end of the connecting rod will squeeze the sliding rod, causing the sliding rod to move upward. At this time, the other end of the connecting rod will rotate on the sliding rod. When the disc rotates to 180° and continues to rotate, it will drive the sliding rod to move downward through the connecting rod, so that the sliding rod moves up and down reciprocally. The up and down reciprocating movement of the sliding rod will drive the clamping plate and the rotating plate to move up and down reciprocally. The up and down reciprocating movement of the two clamping plates and the two rotating plates will drive the frame to move up and down reciprocally. The frame will drive the second filter hopper and the first filter hopper to move up and down reciprocally. Subsequently, the personnel can put the iron ore concentrate to be filtered into the first filter hopper. The up and down reciprocating movement of the first filter hopper can screen the iron ore concentrate, and all the larger impurities in the iron ore concentrate can be filtered out. The filtered iron ore concentrate will fall into the second filter hopper, while the impurities will remain in the first filter hopper. Subsequently, under the action of the up and down reciprocating movement of the second filter hopper, the iron ore concentrate in the second filter hopper can be filtered for the second time, and the smaller impurities in the iron ore concentrate can be filtered out. Subsequently, the filtered iron ore concentrate will fall to the bottom of the inner cavity of the filter barrel and then be discharged from the discharge pipe, which is convenient for the personnel to collect, ensuring that the iron ore concentrate can be filtered for the second time and ensuring that the filtered iron ore concentrate does not contain smaller impurities, so that the purity of the filtered iron ore concentrate is higher.

[0023] In the above technical solution, further, the connecting rod is movably connected with the movable groove, the sliding rod is slidably connected with the movable groove, the top end of the sliding rod is tightly welded to the clamping plate, the top end of the sliding rod is slidably connected with the rectangular groove, the two output shafts of the dual-axis motor are both slidably connected with the filter barrel, and the two output shafts of the dual-axis motor are respectively rotatably connected with the two movable grooves.

[0027] In the above technical solution, further, the bottom of the inner cavity of the filter barrel is of an inclined structure.

[0028] In this technical solution, it is ensured that the iron ore concentrate at the bottom of the inner cavity of the filter barrel can be discharged through the discharge pipe.

[0029] The beneficial effects of the present utility model are as follows:

[0030] 1. For the environment-friendly filter for iron ore concentrate production, by setting the power assembly and driving the power assembly, the power assembly will drive the two clamping plates and the two rotating plates to move up and down reciprocally. The up-and-down reciprocating movement of the two clamping plates and the two rotating plates will drive the frame to move up and down reciprocally. The frame will drive the second filter hopper and the first filter hopper to move up and down reciprocally. Subsequently, the operator can put the iron ore concentrate to be filtered into the first filter hopper. The up-and-down reciprocating movement of the first filter hopper can screen the iron ore concentrate, and all the larger impurities in the iron ore concentrate can be filtered out. The filtered iron ore concentrate will fall into the second filter hopper, while the impurities will remain in the first filter hopper. Subsequently, under the action of the up-and-down reciprocating movement of the second filter hopper, the iron ore concentrate in the second filter hopper can be filtered for the second time, and the smaller impurities in the iron ore concentrate can be filtered out. Subsequently, the filtered iron ore concentrate will fall to the bottom of the inner cavity of the filter barrel and then be discharged through the discharge pipe, which is convenient for the operator to collect, ensuring that the iron ore concentrate can be filtered for the second time, ensuring that the filtered iron ore concentrate does not contain smaller impurities, and thus making the filtered iron ore concentrate have a higher purity.

[0077] Working principle: When in use, the operator can first start the double-shaft motor 18. The two output shafts of the double-shaft motor 18 will drive two discs 15 to rotate respectively. The rotation of the discs 15 will drive one end of the connecting rod 16 to rotate. At the same time, one end of the connecting rod 16 will rotate on the disc 15. The other end of the connecting rod 16 will squeeze the sliding rod 17, causing the sliding rod 17 to move upward. At this time, the other end of the connecting rod 16 will rotate on the sliding rod 17. When the disc 15 rotates to 180° and continues to rotate, it will drive the sliding rod 17 to move downward through the connecting rod 16, so that the sliding rod 17 moves up and down reciprocally. The up and down reciprocal movement of the sliding rod 17 will drive the clamping plate 3 and the rotating plate 4 to move up and down reciprocally. The up and down reciprocal movement of the two clamping plates 3 and the two rotating plates 4 will drive the frame 7 to move up and down reciprocally. The frame 7 will drive the second filter hopper 10 and the first filter hopper 9 to move up and down reciprocally. Subsequently, the operator can put the iron ore concentrate to be filtered into the first filter hopper 9. The up and down reciprocal movement of the first filter hopper 9 can screen the iron ore concentrate, and all the larger impurities in the iron ore concentrate can be filtered out. The filtered iron ore concentrate will fall into the second filter hopper 10, while the impurities will remain in the first filter hopper 9. Subsequently, under the action of the up and down reciprocal movement of the second filter hopper 10, the iron ore concentrate in the second filter hopper 10 can be filtered for the second time, and the smaller impurities in the iron ore concentrate can be filtered out. Subsequently, the filtered iron ore concentrate will fall to the bottom of the inner cavity of the filter barrel 1 and then be discharged from the discharge pipe 19, which is convenient for the operator to collect, ensuring that the iron ore concentrate can be filtered twice and ensuring that the filtered iron ore concentrate does not contain smaller impurities, so that the purity of the filtered iron ore concentrate is higher;

[0078] After the filtration is completed, the operator can turn off the double-shaft motor 18 and then move the limit block 12. The limit block 12 moves in the sliding groove 11 and squeezes the spring 13 to contract until one end of the limit block 12 moves out of the top of the first filter hopper 9. At this time, the limit block 12 can release the limit on the first filter hopper 9. The operator can take out the first filter hopper 9 from the placement groove 8 through the two handles to clean the impurities in the first filter hopper 9. Subsequently, the operator can rotate the two threaded rods 5 respectively. Under the action of the thread, the rotation of the threaded rods 5 will move upward. At the same time, the upward movement of the threaded rods 5 will drive the lower pressing plate 6 to move upward until the bottom of the lower pressing plate 6 is far from the top of the frame 7. At this time, the operator can rotate the rotating plate 4 until the rotating plate 4 rotates 180° on the clamping plate 3. At this time, the operator can remove the frame 7 and the second filter hopper 10 from the two clamping plates 3 to clean the impurities in the second filter hopper 10, ensuring that it is convenient for the operator to clean the impurities in the first filter hopper 9 and the second filter hopper 10.
