Description

Technical Field

[0001] This utility model relates to the field of ramming material screening technology, specifically a multi-stage ramming material screening machine. Background Technology

[0002] Ramming mix refers to unshaped refractory materials that are constructed by ramming (manual or mechanical) and hardened under heating at temperatures above room temperature. Zircon has high refractoriness, low coefficient of thermal expansion, good thermal shock stability, and excellent resistance to molten steel and alkaline slag erosion, and can be used as a high-grade refractory material. Ramming mix needs to be screened after processing.

[0003] The prior art patent document CN219112145U provides a cleaning device for a multi-stage tamping material screening machine, including a housing, a cleaning brush plate, and a rotating shaft. Through the action of a guide wheel, a connecting rope, a drive wheel, a cleaning brush plate, a rotating shaft, a half gear, a toothed plate, a screening frame, a movable block, a spring, a guide rod, and a rotating rod, this cleaning device achieves the purpose of rapid cleaning. It solves the problem that existing multi-stage screening machines do not have a cleaning structure, and the screen mesh is prone to clogging during long-term use, thereby reducing its screening efficiency. Manual cleaning is time-consuming and labor-intensive, which limits its development and promotion.

[0004] Although the device has many beneficial effects, the following problems still exist: During the use of the device, manual unloading of the zircon ramming material after screening is required, which is cumbersome, time-consuming and labor-intensive; secondly, the brush bristles of the cleaning plate accumulate waste after long-term use, affecting the cleaning effect, which needs to be improved. In view of this, we propose a multi-stage ramming material screening machine. Utility Model Content

[0008] Therefore, the purpose of this utility model is to provide a multi-stage screening machine for ramming material, which makes unloading the zircon ramming material after screening easier, saves time and effort, facilitates disassembly and cleaning of the screen, and prevents clogging.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A multi-stage tamping material screening machine includes a housing. A fixed shaft is located at the top of the housing's inner cavity. A screening frame is slidably connected to the outer circumference of the fixed shaft. A mounting frame is located on the side wall of the housing. A discharge assembly is located inside the mounting frame. The discharge assembly includes a first motor located at the top of the mounting frame. A worm gear is located at the output end of the first motor. Multiple worm wheels mesh with the outer circumference of the worm gear. A rotating shaft is located on the inner circumference of the worm wheels. A gear is located at the other end of the outer circumference of the rotating shaft. Each of the multiple gears meshes with a first toothed plate. Two push plates are located at the other end of the first toothed plates. A pin is hinged between the two push plates. Multiple screens are slidably connected to the side wall of the screening frame's inner cavity. Mounting assemblies are located on both sides of the screens. A drive assembly is located on the side wall of the housing. Second springs are sleeved at both ends of the outer circumference of the fixed shaft, located within the housing's inner cavity. The first motor is electrically connected to an external power source. The mounting frame improves the rotational stability of the worm gear and rotating shaft, preventing them from falling off.

[0012] In a preferred embodiment of the multi-stage tamping material screening machine of this utility model, the mounting assembly includes a slide rail, a sliding groove is formed on the inner side wall of the screening frame, a locking groove is formed on the top of the slide rail, and multiple first springs are provided inside the side wall of the screening frame. A lever is provided at the bottom of each first spring, and a locking block is provided at the bottom of the lever. The sliding groove is slidably connected to the slide rail, making the screen fit more tightly against the inner side wall of the screening frame, preventing the zircon tamping material from flowing out.

[0013] In a preferred embodiment of this utility model's multi-stage tamping material screening machine, the size and position of the push plate match the size and position of the screens, and the mesh count of the multiple screens increases sequentially from top to bottom. The position of the push plate facilitates the operator in positioning the screens for installation.

[0014] In a preferred embodiment of the multi-stage screening machine for ramming material according to this utility model, the dimensions and positions of the slide rail match the dimensions and positions of the slide groove, and the dimensions and positions of the slot match the dimensions and positions of the slot block.

[0015] In a preferred embodiment of the multi-stage tamping material screening machine of this utility model, the driving component includes a second motor, the output end of the second motor is provided with a half gear, the half gear meshes with a second toothed plate located on the side wall of the screening frame, and the second motor is electrically connected to an external power source.

[0016] As a preferred embodiment of the multi-stage tamping material screening machine of this utility model, the top of the box is provided with a feed inlet and the bottom of the screening frame is provided with multiple moving wheels.

[0017] As a preferred embodiment of the multi-stage screening machine for ramming material according to this utility model, the side wall of the box is hinged with multiple sealing doors, and each of the sealing doors is provided with a handle at the bottom of its side wall.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This multi-stage ramming material screening machine controls the drive assembly to move the screening frame along a fixed axis. The rebound force of the second spring causes the screening frame to reset, thus causing the screen to reciprocate to screen the zircon ramming material. By turning on the first motor to drive the worm gear to rotate, multiple worm wheels rotate simultaneously, causing the rotating shaft to rotate simultaneously, which in turn causes multiple gears to rotate simultaneously, causing multiple first tooth plates to move and push out the screened zircon ramming material. Unloading is simpler, saving time and effort. Two push plates are hinged by a pin to rotate, avoiding obstruction of the screen frame during movement.

[0021] This multi-stage tamping material screening machine uses an upward-moving dial plate to move a locking block upward, inserting it into the screen so that the slide rail is inserted into the groove. When the dial plate is released, the rebound force of the first spring moves the locking block downward to insert it into the groove. This makes disassembly and assembly easier, facilitating screen cleaning and preventing clogging. Attached Figure Description

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a multi-stage tamping material screening machine, including:

[0035] Please see Figures 1-5This embodiment of a multi-stage tamping material screening machine includes a housing 1. A fixed shaft 2 is welded to the top of the inner cavity of the housing 1. A screening frame 3 is slidably connected to the outer circumference of the fixed shaft 2. An installation frame 4 is welded to the side wall of the housing 1. A discharge assembly 5 is rotatably connected inside the installation frame 4. The discharge assembly 5 includes a first motor 501 located at the top of the installation frame 4. A worm gear 502 is fixedly mounted at the output end of the first motor 501. Multiple worm wheels 503 are meshed on the outer circumference of the worm gear 502. A rotating shaft 504 is fixedly mounted on the inner circumference of the worm wheels 503. A gear 505 is fixedly mounted at the other end of the outer circumference of the rotating shaft 504. Multiple gears 505 mesh with a first toothed plate 506. Two push plates 507 are fixedly mounted at the other end of the first toothed plate 506. A pin 508 is hinged at the connection between the two push plates 507. Multiple screens 6 are slidably connected to the side wall of the inner cavity of the screening frame 3. Mounting components 7 are fixedly installed on the side walls, and driving components 8 are fixedly installed on the side walls of the housing 1. Second springs 9 located in the inner cavity of the housing 1 are sleeved at both ends of the outer circumference of the fixed shaft 2. The first motor 501 is electrically connected to an external power source. By controlling the driving components 8, the screening frame 3 is driven to move along the fixed shaft 2. The rebound force of the second springs 9 drives the screening frame 3 to reset, thereby causing the screen 6 to move back and forth to screen the zircon ramming material. By turning on the first motor 501, the worm gear 502 is driven to rotate, thereby causing multiple worm wheels 503 to rotate simultaneously, driving the rotating shaft 504 to rotate simultaneously, which in turn causes multiple gears 505 to rotate simultaneously, driving multiple first toothed plates 506 to move and push out the screened zircon ramming material. Unloading is more convenient, saving time and effort. Two push plates 507 are hinged to rotate by the pin shaft 508 to avoid the screening frame 3 being blocked by the push plates 507 when it moves.

[0036] It is worth noting that, in order to improve the cleaning effect of the screen 6, the installation component 7 specifically includes a slide rail 701, a slide groove 702 is provided on the inner side wall of the screening frame 3, a slot 703 is provided on the top of the slide rail 701, and multiple first springs 704 are fixed inside the side wall of the screening frame 3. A lever 705 is fixed at the bottom of the first spring 704, and a locking block 706 is fixed at the bottom of the lever 705. By moving the lever 705 upward, the locking block 706 moves upward and inserts into the screen 6, so that the slide rail 701 is inserted into the slide groove 702. When the lever 705 is released, the rebound force of the first spring 704 drives the locking block 706 downward to insert into the slot 703. This makes disassembly and assembly easier, facilitates the removal and cleaning of the screen 6, and prevents clogging.

[0037] Next, in order to facilitate the sorting of ramming materials of different particle sizes, the size and position of the push plate 507 are matched with the size and position of the screen 6. The mesh count of multiple screens 6 increases sequentially from top to bottom. By using multiple screens 6 with the mesh count increasing sequentially from top to bottom, it is easy to sieve the zircon ramming material into different particle sizes.

[0038] Meanwhile, in order to improve stability, specifically, the size and position of the slide rail 701 are matched with the size and position of the slide groove 702, and the size and position of the slot 703 are matched with the size and position of the slot block 706. The slot 703, which matches the size and position of the slot block 706, makes the installation of the screen 6 more stable.

[0039] Furthermore, to facilitate the screening of zircon ramming material, the drive assembly 8 specifically includes a second motor 801. A half gear 802 is fixedly mounted at the output end of the second motor 801. The half gear 802 meshes with a second toothed plate 803 located on the side wall of the screening frame 3. The second motor 801 is electrically connected to an external power source. By turning on the second motor 801, the half gear 802 is driven to rotate, thereby causing the second toothed plate 803 to move and driving the screening frame 3 to move. When the half gear 802 rotates to disengage, the screening frame 3 resets, thereby causing the screen 6 to move cyclically to screen the ramming material.

[0040] It is worth noting that, in order to facilitate the movement of the screening frame 3, a feed inlet 10 is welded to the top of the box 1, and multiple moving wheels 11 are threaded to the bottom of the screening frame 3. Zircon tamping material is added through the feed inlet 10, and the moving wheels 11 make the movement of the screening frame 3 more stable.

[0041] Finally, to prevent the ramming material from splashing out during screening, the side wall of the box 1 is hinged with multiple sealing doors 12, and each sealing door 12 is fixed with a handle 13 at the bottom of its side wall. By pulling the handle 13, the sealing door 12 can be opened to unload the zircon ramming material.

[0042] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0043] The device or equipment models mentioned in this article may be as follows:

[0044] First motor 501: Y90S-2;

[0045] Second motor 801: Z90S-2.

[0046] Combination Figures 1-5 The specific usage process of the multi-stage screening machine for rammed material according to this embodiment is as follows:

[0047] 1. When this device is needed for multi-stage screening of rammed material, add zircon rammed material into the feed inlet 10, start the second motor 801 to make the half gear 802 rotate and drive the second toothed plate 803 to move. When the half gear 802 rotates to disengage, the rebound force of the second spring 9 drives the screening frame 3 to reset, thereby causing the screening frame 3 to move back and forth and drive the screen 6 to move cyclically to screen the rammed material. After screening, pull the handle 13 to open the sealing door 12, start the first motor 501 to make the worm 502 rotate and drive multiple worm wheels 503 to rotate simultaneously, thereby causing multiple rotating shafts 504 to rotate simultaneously and drive multiple gears 505 to rotate simultaneously, and then causing multiple first toothed plates 506 to move and push out the screened zircon rammed material.

[0048] 2: Move the lever 705 upward to move the locking block 706 upward, pull out the screen 6 for cleaning, and after cleaning, insert the screen 6 so that the slide rail 701 is inserted into the slide groove 702. Release the lever 705, and the rebound force of the first spring 704 will move the locking block 706 downward to insert into the slot 703.

[0049] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
