Description

Technical Field

[0001] This invention relates to the field of iron concentrate production technology, specifically to a screening system for testing iron concentrate production. Background Technology

[0002] Iron concentrate is a core raw material for blast furnace ironmaking and sinter production. Iron concentrate provides high-grade and stable-quality raw materials for steelmaking, ensuring the efficient operation of subsequent ironmaking and steelmaking processes and improving the performance of the final steel. Screening is necessary in the production and testing of iron concentrate to ensure that the particle size distribution meets the standards and to avoid the impact of excessively coarse or fine particles on smelting performance and testing accuracy. Screening is a key physical processing step in the production and testing of iron concentrate. However, during the screening process, vibrating screens can cause some iron concentrate to splash out, resulting in material waste and affecting the testing. It is important to reduce the impact of splashing during vibrating screens and to observe the internal screening conditions during screening, and to use multiple screening stages. Summary of the Invention

[0003] The purpose of this invention is to provide a screening system for testing iron concentrate production, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A screening system for iron concentrate production and testing includes a support assembly, which provides overall support points. The support assembly includes a support base, on which are provided several storage boxes for storing screened iron concentrate. An unscreened collection box is provided at the right end of the support base. The screening assembly is used to screen the produced iron concentrate in multiple stages. The screening assembly is installed on the support assembly and includes a screening box and a dust cover inserted into the top of the screening box. The screening box has symmetrical protrusions on both sides, and each protrusion is equipped with a spring. The bottom of the inner wall of the screening box has several limiting grooves, and each limiting groove is equipped with a screening screen plate.

[0005] Furthermore, each corner of the inner wall of the support base is provided with a fixing block, and the fixing block and the support base are integrally formed.

[0006] In this invention, the fixed block provides a point of force, which helps to provide an installation point for the screening component and does not affect the up-and-down vibration and screening of the screening component in the support.

[0007] Specifically, the support base is provided with several storage boxes, and the storage boxes and the support base are integrally formed. Each storage box has a slot on its front end face. The width of the inner wall of the slot is adapted to the width of the outer wall of the storage box. A handle is provided on the outer wall of the storage box.

[0008] In this invention, three storage boxes work together to collect and screen iron concentrate of different particle sizes for corresponding testing. The handle provides a point of leverage, making it easy to pull out and retrieve the storage boxes.

[0009] It should be noted that the right end of the support base is also provided with a tray. The tray and the support base are integrally formed. The tray has a groove. The width of the outer wall of the collection frame is adapted to the width of the inner wall of the groove. The top of the tray is provided with a protective plate.

[0010] In this invention, the collection frame is equipped with a handle, which helps to pull the collection frame out. The collection frame collects unscreened iron concentrate, which helps the screening component to continuously screen and distribute the iron concentrate. The protective plate is fixed to the tray by bolts, and with the cooperation of the protective plate, the iron concentrate discharged from the end of the screening component is prevented from leaving the collection frame and affecting the centralized collection.

[0011] Furthermore, a vibration motor is provided at the middle of both sides of the screening box. The vibration motor is fixed to the screening box by bolts. The protrusion and the screening box are integrally formed. One end of the spring is fixed to the protrusion by bolt clamp, and the other end is fixed to the fixing block by bolt clamp.

[0012] In this invention, the control switch on the outer wall of the vibrating motor is electrically connected to an external power source via a wire. When the control switch is turned on, the two vibrating motors are started, which vibrate the screening box. The spring has elasticity and connects the protrusion and the fixed block to achieve the connection between the screening box and the support base without affecting the up-and-down vibration screening of the screening box in the support base.

[0013] Specifically, the screening box is provided with a receiving hopper at the right end, the receiving hopper is fixed to the screening box by bolts, and the end of the receiving hopper corresponds to the collection frame.

[0014] In this invention, the installation of the receiving hopper helps guide the iron concentrate powder to be screened in the screening box to be discharged, collected centrally, and convenient for continuous screening.

[0015] It is worth noting that the width of the outer wall of the dust cover is adapted to the width of the outer wall of the screening box. The dust cover is provided with several transparent windows, which are made of tempered glass and are bonded to the dust cover. Handles are symmetrically provided on the upper surface of the dust cover near the edge. A sealing gasket is provided on the lower surface of the dust cover, and the top of the sealing gasket is bonded to the dust cover. The width of the outer wall of the sealing gasket is adapted to the width of the inner wall of the screening box. A feed hopper is provided on the upper surface of the dust cover near the left end.

[0016] In this invention, the dust cover and screening box are connected by a plug-in assembly. With the help of the transparent window, it is helpful to observe the screening condition inside the screening box without opening the dust cover. With the help of the sealing gasket, it is helpful to stably connect and install the dust cover and screening box. The installation of the feed hopper allows for continuous addition, screening, and mixing of iron concentrate for production that needs to be tested without opening the dust cover.

[0017] In addition, the width of the inner wall of the limiting groove is adapted to the width of the outer wall of the screening screen plate. The screening screen plate is fixed to the screening box by flat-head bolts. The screening box is symmetrically provided with latches on both sides near the top. The dust cover is provided with hooks corresponding to the latches.

[0018] In this invention, the mesh size of the screening screen decreases from left to right, with mesh sizes of 160 mesh, 200 mesh, and 325 mesh from left to right. The corresponding iron concentrate is screened out and falls into the corresponding storage box for storage. The lock is fixed to the screening box by bolts, and the lock is hooked to the corresponding hook to fix the dust cover to the screening box. The lower surface of the screening box is provided with a partition plate between two adjacent screening screens. The partition plate is inserted between adjacent storage boxes to prevent the falling iron concentrate from entering the adjacent storage boxes.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a screening box with multiple screening screens, which is elastically connected to a fixed block on a support base via protrusions and springs. With the assistance of a vibrating motor, it performs multi-stage screening of the iron concentrate to be tested. The dust cover is inserted into the screening box and, with the help of hooks and locks, increases the stability of the installation and reduces material splashing during the screening process, thus preventing material waste and affecting the test. The storage box collects the iron concentrate screened by different screening screens, and the collection frame collects the unscreened iron concentrate.

[0020] 2. This invention allows observation of the screening process in the screening box without opening the dust cover by setting a transparent window. Iron concentrate to be screened is continuously added with the help of the feed hopper. Unscreened iron concentrate is guided into the collection box for centralized storage with the help of the receiving hopper. The partition plate separates adjacent storage boxes to reduce mutual interference. The sealing gasket increases the stability of the connection between the dust cover and the screening box.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-5 This embodiment provides a technical solution: A screening system for iron concentrate production and testing includes a support assembly, which provides the overall support force point. The support assembly includes a support base 1, which is provided with a plurality of storage boxes 12 for storing screened iron concentrate. The right end of the support base 1 is provided with a collection box 132 for unscreened iron concentrate. Furthermore, each corner of the inner wall of the support base 1 is provided with a fixing block 10, and the fixing block 10 and the support base 1 are integrally formed.

[0025] In this invention, the fixing block 10 provides a point of force, which helps to provide an installation point for the screening component and does not affect the up-and-down vibration and screening of the screening component in the support 1.

[0026] Specifically, the support base 1 is provided with several storage boxes 11. The storage boxes 11 and the support base 1 are integrally formed. Each storage box 11 has a slot 110 on its front end face. The width of the inner wall of the slot 110 is adapted to the width of the outer wall of the storage box 12. The outer wall of the storage box 12 is provided with a handle.

[0027] In this invention, with the cooperation of three storage boxes 12, iron concentrate of different particle sizes is collected and screened for corresponding testing. The handle provides a point of force, making it convenient for the storage box 12 to be pulled out and put into use.

[0028] Secondly, a tray 13 is provided on the right end of the support base 1. The tray 13 and the support base 1 are integrally formed. A groove 130 is provided on the tray 13. The width of the outer wall of the collection frame 132 is matched with the width of the inner wall of the groove 130. A protective plate 131 is provided on the top of the tray 13.

[0029] In this invention, the collection frame 132 is provided with a handle, which helps to pull out the collection frame 132. The collection frame 132 collects unscreened iron concentrate, which helps the screening component to continuously screen and distribute the iron concentrate. The protective plate 131 is fixed to the tray 13 by bolts. With the cooperation of the protective plate 131, the iron concentrate discharged from the end of the screening component is prevented from leaving the collection frame 132, thus affecting the centralized collection.

[0030] It should be noted that the screening component is used to screen the produced iron concentrate in multiple stages. The screening component is installed on the support component and includes a screening box 2 and a dust cover 3 inserted into the top of the screening box 2. The screening box 2 has symmetrical protrusions 20 on both sides, and each protrusion 20 is equipped with a spring 200. Several limiting grooves 24 are opened at the bottom of the inner wall of the screening box 2, and each limiting groove 24 is equipped with a screening screen plate 25.

[0031] Furthermore, a vibration motor 4 is provided at the middle of both sides of the screening box 2. The vibration motor 4 is fixed to the screening box 2 by bolts. The protrusion 20 and the screening box 2 are integrally formed. One end of the spring 200 is fixed to the protrusion 20 by bolt clamping, and the other end is fixed to the fixing block 10 by bolt clamping.

[0032] In this invention, the control switch on the outer wall of the vibrating motor 4 is electrically connected to an external power source via a wire. When the control switch is turned on, the two vibrating motors 4 are started to vibrate and cooperate with the screening box 2. The spring 200 has elasticity and connects the protrusion 20 and the fixing block 10 to realize the connection and cooperation between the screening box 2 and the support base 1, without affecting the up and down vibration and screening of the screening box 2 in the support base 1.

[0033] Specifically, the right end of the screening box 2 is provided with a receiving hopper 21, which is fixed to the screening box 2 by bolts, and the end of the receiving hopper 21 corresponds to the collection frame 132.

[0034] In this invention, the receiving hopper 21 helps guide the iron concentrate powder to be screened in the screening box 2 to be discharged, collected centrally, and convenient for continuous screening.

[0035] It is worth noting that the width of the outer wall of the dust cover 3 is adapted to the width of the outer wall of the screening box 2. The dust cover 3 is provided with several transparent windows 30, which are made of tempered glass. The transparent windows 30 are bonded and fixed to the dust cover 3. Handles 31 are symmetrically provided on the upper surface of the dust cover 3 near the edge. A sealing gasket 32 ​​is provided on the lower surface of the dust cover 3.
