Detailed Embodiment

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0019] The present utility model provides as Figures 1-4An iron removal device prepared from quartz sand as shown includes a magnetic adsorption tank 1. A discharge pipe 2 for discharging quartz sand is arranged at the bottom end of the magnetic adsorption tank 1. A storage box 3 for receiving quartz sand is arranged at the bottom end of the discharge pipe 2. A dust shielding mechanism 4 for connecting with the storage box 3 is arranged at the bottom end of the discharge pipe 2. The dust shielding mechanism 4 includes a telescopic cover 42 and a connecting plate 43. An installation ring 41 for connecting with the discharge pipe 2 is arranged at the top end of the telescopic cover 42. Extrusion components 6 for connecting with the storage box 3 are symmetrically arranged at both ends of the connecting plate 43. A sealing ring 5 for sealing between the connecting plate 43 and the storage box 3 is arranged at the bottom end of the connecting plate 43.

[0020] Specifically, the magnetic adsorption tank 1 and the discharge pipe 2 form an existing dry-type electromagnetic iron remover of model ZR0709S-4. By pouring quartz sand into the interior of the magnetic adsorption tank 1 from the feed pipe, when the interior of the magnetic adsorption tank 1 is electrified, a magnetic field is generated by the coil inside the magnetic adsorption tank 1, magnetizing the magnetic conduction net arranged inside. Thus, when the quartz sand passes through the magnetic conduction net, magnetic impurities such as iron will be adsorbed on the magnetic conduction net, and the quartz sand will fall into the discharge pipe 2 for continuous discharge. The quartz sand discharged from the discharge pipe 2 passes through the installation ring 41, the telescopic cover 42, and the connecting plate 43 respectively, and finally falls into the interior of the storage box 3 for storage. The storage box 3 is a box body with an outer edge at the top.

[0021] Specifically, the top end of the installation ring 41 is fixedly connected to the bottom end of the discharge pipe 2. The top end of the telescopic cover 42 is fixedly connected to the bottom end of the installation ring 41. The bottom end of the telescopic cover 42 is fixedly connected to the top end of the connecting plate 43. The top end of the sealing ring 5 is fixedly connected to the bottom end of the connecting plate 43. The shape of the sealing ring 5 corresponds to the shape of the top end of the storage box 3.

[0022] Furthermore, the top end of the installation ring 41 and the bottom end of the discharge pipe 2 are fixedly connected by welding. The telescopic cover 42 is an existing corrugated telescopic pipe. The top end and the bottom end of the telescopic cover 42 are respectively fixedly connected to the bottom end of the installation ring 41 and the top end of the connecting plate 43 by gluing. Through holes are respectively arranged at the top ends of the installation ring 41 and the connecting plate 43. The size of the through holes corresponds to the discharging size of the discharge pipe 2. The inner diameter size of the telescopic cover 42 corresponds to the size of the through holes. The sealing ring 5 is made of rubber material. The top end of the sealing ring 5 and the bottom end of the connecting plate 43 are fixedly connected by gluing.

[0023] Specifically, installation blocks 44 are symmetrically and fixedly connected to both sides of the outer wall of the installation ring 41 respectively. First grooves are respectively arranged at the bottom ends of the installation blocks 44. First magnetic blocks 45 are fixedly connected to the top ends of the inner walls of the first grooves. Second grooves are symmetrically arranged at both sides of the top end of the connecting plate 43 respectively. Second magnetic blocks 46 are fixedly connected to the bottom ends of the inner walls of the second grooves. The thickness of the installation blocks 44 is 1.3 - 1.5 times the thickness of the installation ring 41.

[0024] Further, the cross-section of the mounting block 44 is T-shaped, the first magnetic block 45 and the second magnetic block 46 are of opposite magnetic poles. The thickness of the mounting block 44 specifically needs to be determined according to the thickness after the telescopic cover 42 is completely retracted. The first magnetic block 45 and the second magnetic block 46 are in the same straight line position in the vertical direction. When sand receiving is not carried out, the telescopic cover 42 can be retracted and received. Through the magnetic attraction of the first magnetic block 45 and the second magnetic block 46, the mounting block 44 is connected to the connecting plate 43, so as to achieve the receiving effect on the connecting plate 43.

[0025] Specifically, the extrusion assembly 6 includes a buckling block 61. The buckling block 61 is used for buckling the bottom end of the top of the storage box 3. The top end of the buckling block 61 is fixedly connected with a moving rod 62 for driving the buckling block 61 to move. A round hole for inserting the moving rod 62 is opened at the top end of the connecting plate 43. A pushing spring 63 is sleeved on the outer wall of the moving rod 62. The top end of the moving rod 62 is fixedly connected with a baffle 64.

[0026] Further, two sets of extrusion assemblies 6 are provided, symmetrically arranged at both ends of the connecting plate 43. The buckling block 61 and the moving rod 62 form an L shape. The diameter of the moving rod 62 is 0.98 times the diameter of the round hole. The inner diameter of the pushing spring 63 is 1.2 times the diameter of the round hole. The size of the baffle 64 is 1.2 times the outer diameter of the pushing spring 63. The pushing spring 63 is only sleeved on the outer wall of the moving rod 62 and is not fixedly connected. Limited by the baffle 64 and the buckling block 61, the pushing spring 63 cannot move out of the moving rod 62. When using the connecting plate 43, the buckling block 61 needs to be turned first, and then the connecting plate 43 is moved so that the bottom end of the sealing ring 5 fits the top end of the storage box 3. At this time, by pressing the baffle 64, while the baffle 64 squeezes the pushing spring 63, the baffle 64 drives the moving rod 62 to move towards the storage box 3, and the moving rod 62 drives the buckling block 61 to move. At this time, the buckling block 61 is rotated in the reverse direction again so that the top end of the buckling block 61 is at the position of the bottom end of the outer edge of the storage box 3. Under the restoring force of the pushing spring 63, the pushing spring 63 pushes the baffle 64 to move away from the connecting plate 43, and the baffle 64 drives the buckling block 61 to move synchronously by driving the moving rod 62, so that the top end of the buckling block 61 tightly fits the bottom end of the outer edge of the storage box 3, and at the same time, the sealing ring 5 is squeezed, so as to achieve sealing between the connecting plate 43 and the storage box 3.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
