Description

Technical Field

[0001] This utility model relates to the technical field of slag powder storage equipment, and specifically discloses a storage device for slag powder production. Background Technology

[0002] Slag powder is a powdery substance produced by drying and grinding the waste slag generated during the smelting of pig iron in steel plants. Its full name is granulated blast furnace slag powder, commonly known as mineral powder or water slag powder. Slag powder is often used in the fields of construction, soil improvement, filling materials and preparation of other building materials. The produced slag powder is usually stored in storage devices for subsequent storage, transportation and use.

[0003] Chinese patent CN216685770U discloses a slag powder storage device, including a support frame. A tank is fixedly installed on the upper end of the support frame. Crossbars are fixed on the upper end of the tank relative to the inner wall. A conical block is fixedly connected to the opposite end of the two crossbars. This invention can filter slag powder entering the tank, preventing impurities from affecting the quality of the slag powder in the tank and effectively ensuring its quality. Simultaneously, during the filtration process, the screen can be tapped to vibrate, accelerating the filtration process. This ensures the quality of the slag powder in the tank without affecting the conveying efficiency and effectively improves the function and practicality of the slag powder storage device. However, during use, slag powder easily adheres to the gaps between the teeth of the fixed bevel gear and the transmission bevel gear, affecting the transmission effect of these two gears and consequently the performance of the round rod, push frame, and pulley. Position adjustment and fixing in the storage device are inconvenient, and the discharge pipe's height from the ground cannot be adjusted according to actual usage needs, increasing the limitations of the device. Therefore, to solve these problems, this invention proposes a storage device for slag powder production. Utility Model Content

[0004] The present invention aims to provide a storage device for the production of slag powder, which can ensure that the support shaft drives the first scraper to rotate smoothly so that the first scraper contacts the lower plane of the screen basket during rotation, causing the screen basket to vibrate slightly and preventing the slag powder from clogging the screen holes. The device is easy to adjust and fix, and the height of the discharge pipe from the ground can be adjusted according to actual use needs, reducing the limitations of the device in actual use.

[0005] This utility model is achieved through the following technical solution:

[0006] A storage device for producing slag powder includes a storage structure comprising a silo. A support ring is provided at the upper inner end of the silo. A first top plate and a second top plate are respectively connected to the upper two sides of the silo. A screening and feeding mechanism is provided inside the silo, comprising a screen basket. A support shaft is threaded through the middle of the screen basket. First scrapers are connected to both sides of the support shaft. Second scrapers are connected to the ends of the two first scrapers away from the support shaft. The second scrapers and first scrapers slide in contact with the inner wall of the silo and the lower plane of the screen basket, respectively. A spiral rod is connected to the lower end of the support shaft. A support mechanism is provided outside the silo, comprising a bracket. Support legs are connected to the four corners of the bracket. Mounting blocks are provided on one side of each of the four support legs. Mounting plates are connected to the sides of the mounting blocks away from the support legs. Telescopic rods are connected to the ends of the mounting plates away from the mounting blocks. Universal wheels are connected to the telescopic ends of the telescopic rods.

[0007] As a further feature of the above scheme, the lower end of the silo is connected to a discharge pipe, and one end of the discharge pipe is equipped with a valve to control the opening and closing of the discharge pipe. Above the support ring, multiple mounting shafts are arranged in a circumferential array, and the multiple mounting shafts are detachably connected to the screen basket for easy installation and maintenance of the screen basket. The bottom of the screen basket is provided with multiple screen holes arranged in a circumferential array to facilitate the passage of small slag powder particles through the screen holes into the silo for storage.

[0008] As a further feature of the above scheme, the support shaft is rotatably connected to the screen basket, which can avoid conflict between the support shaft and the screen basket. Multiple stirring rods arranged in a linear array are provided on the outside of the support shaft, which can disperse the slag powder in the hopper during the discharge process of the discharge pipe. The first top plate and the second top plate are both detachably connected to the hopper, which facilitates the installation and maintenance of the first top plate and the second top plate. It is helpful to remove the second top plate before cleaning the screen basket and then reinstall the second top plate after the screen basket is cleaned.

[0009] As a further feature of the above scheme, the upper end of the support shaft passes through the interior of the first top plate and is rotatably connected to the first top plate. A motor is connected to the upper end of the support shaft, which can provide power for the rotation of the support shaft and its connecting parts. A base is connected to the outside of the motor. The lower end of the base is connected to the first top plate, which can provide stable support for the motor and facilitate the installation and maintenance of the motor and the base. A feed pipe is connected to one side of the first top plate, which can facilitate connection with the existing pipeline to inject slag powder into the silo.

[0010] As a further feature of the above solution, each of the four support legs has two first connecting holes inside, and each of the two sides of the mounting block has two second connecting holes. Bolts are simultaneously installed through the interior of the second and first connecting holes, and nuts are threaded onto the outer side of the bolts to facilitate the disassembly and maintenance of the mounting block.

[0011] As a further feature of the above scheme, the telescopic rods are connected to the terminal equipment via electrical signals, making it convenient for users to control the extension and retraction of the four telescopic rods. A controller is provided on one side of one of the support legs to facilitate the opening and closing of the motor and valves in the device.

[0012] In this invention, at least one of the four universal wheels is a brake wheel, and the shaft of the auger extends into the discharge pipe to a certain depth.

[0013] The present invention has the following beneficial effects during use:

[0014] The separate design of the first and second top plates in the storage structure allows for the removal of only the second top plate before cleaning the screen basket, keeping the first top plate stationary. This reduces the workload of disassembling and assembling components such as the motor and support shaft, and improves the efficiency of screen basket cleaning. The use of two first scrapers allows the support shaft to contact the lower surface of the screen basket during rotation, causing the screen basket to vibrate slightly and preventing slag powder from clogging the screen holes. The use of two second scrapers allows the slag powder adhering to the inner wall of the hopper to be scraped off during the discharge process.

[0015] The combination of four support legs, mounting blocks, telescopic rods, and casters in the support mechanism allows the mounting blocks to be installed on one side of the support legs according to actual usage needs. The terminal equipment simultaneously controls the extension of the four telescopic rods, separating the support legs from the ground and bringing the casters into contact with the ground to provide support for the device. The device can then be adjusted to a suitable position by the rolling of the casters. At the same time, the extension and retraction of the telescopic rods can also move the hopper up and down to adjust the height of the discharge pipe from the ground, making it easier to align the discharge pipe with the original receiving device and reducing the limitations of the device in actual use.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-7 This application will be described in detail with reference to the embodiments.

[0027] An embodiment discloses a storage device for slag powder production, including a storage structure 1. The storage structure 1 includes a silo 11. A support ring 112 is provided at the upper inner side of the silo 11. A first top plate 13 and a second top plate 14 are respectively connected to the upper two sides of the silo 11. A screening and feeding mechanism 2 is provided inside the silo 11. The screening and feeding mechanism 2 includes a screen basket 21. A support shaft 22 is provided through the middle of the screen basket 21. First scrapers 24 are connected to both sides of the support shaft 22. A second scraper 25 is connected to the end of each of the two first scrapers 24 away from the support shaft 22. The second scraper 25 and the first scraper 24 are respectively slidably engaged with the inner wall of the hopper 11 and the lower plane of the screen basket 21. The lower end of the support shaft 22 is connected to a spiral rod 26. A support mechanism 3 is provided on the outside of the hopper 1. The support mechanism 3 includes a bracket 31. Each of the four corners of the bracket 31 is connected to a support leg 32. Each of the four support legs 32 is provided with a mounting block 33 on one side. The side of the mounting block 33 away from the support leg 32 is connected to a mounting plate 35. The end of the mounting plate 35 away from the mounting block 33 is connected to a telescopic rod 36. The telescopic end of the telescopic rod 36 is connected to a caster wheel 37.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the lower end of the hopper 11 is connected to a discharge pipe 111. One end of the discharge pipe 111 is equipped with a valve 12, which can control the opening and closing of the discharge pipe 111. Above the support ring 112, there are multiple mounting shafts 113 arranged in a circumferential array. All of the mounting shafts 113 are detachably connected to the screen basket 21, which facilitates the installation and maintenance of the screen basket 21. The bottom of the screen basket 21 is provided with multiple screen holes 211 arranged in a circumferential array, which facilitates small slag powder particles to pass through the screen holes 211 and fall into the hopper 11 for storage.

[0029] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the support shaft 22 is rotatably connected to the screen basket 21, which can avoid conflict between the support shaft 22 and the screen basket 21. Multiple stirring rods 23 arranged in a linear array are provided on the outside of the support shaft 22, which can disperse the slag powder in the hopper 11 during the discharge process of the discharge pipe 111. The first top plate 13 and the second top plate 14 are detachably connected to the hopper 11, which facilitates the installation and maintenance of the first top plate 13 and the second top plate 14. It is helpful to remove the second top plate 14 before cleaning the screen basket 21 and then reinstall the second top plate 14 after cleaning the screen basket 21.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, the upper end of the support shaft 22 passes through the interior of the first top plate 13 and is rotatably connected to the first top plate 13. The upper end of the support shaft 22 is connected to a motor 27, which can provide power for the rotation of the support shaft 22 and its connecting parts. The outer side of the motor 27 is connected to a base 271. The lower end of the base 271 is connected to the first top plate 13, which can provide stable support for the motor 27 and facilitate the installation and maintenance of the motor 27 and the base 271. A feed pipe 131 is connected to one side of the first top plate 13, which can be easily connected to the existing pipeline to inject slag powder into the silo 11.

[0031] like Figure 6 and Figure 7 As shown, each of the four support legs 32 has two first connecting holes 321 inside, and each of the two sides of the mounting block 33 has two second connecting holes 331. Bolts 34 are simultaneously installed through the interior of the second connecting holes 331 and the first connecting holes 321. Nuts 341 are threaded onto the outer side of the bolts 34, which facilitates the disassembly, assembly and maintenance of the mounting block 33.

[0032] like Figure 2 As shown, the telescopic rod 36 is connected to the terminal device via an electrical signal, which allows the user to control the extension and retraction of the four telescopic rods 36. A controller 4 is provided on one side of one of the support legs 32 to facilitate the opening and closing of the motor 27 and valve 12 in the device.

[0033] The slag powder production storage device disclosed in this embodiment connects the original conveying pipe to the feed pipe 131 before use. The slag powder to be stored is injected into the silo 11 through the feed pipe 131. The controller 4 starts the motor 27, which drives the first scraper 24 and the second scraper 25 to rotate through the support shaft 22. During the rotation, the first scraper 24 slides under the screen plate of the screen basket 21, causing the screen basket 21 to vibrate slightly so that the small slag powder particles can pass smoothly through the screen holes 211 and fall to the bottom of the screen basket 21. After a sufficient amount of slag powder has been injected, the injection is stopped, the second top plate 14 is removed, the large slag particles are cleaned out of the screen basket 21, and then the second top plate 14 is reinstalled.

[0034] When it is necessary to discharge the slag powder stored in the silo 11, determine whether it is necessary to adjust the ground clearance of the lower end of the discharge pipe 111 based on the existing receiving device. If no adjustment is needed, directly connect the existing receiving device to the discharge pipe 111, use the controller 4 to open the valve 12 and start the motor 27, so that the motor 27 drives the stirring rod 23, the second scraper 25 and the screw rod 26 to rotate through the support shaft 22. During the rotation, the stirring rod 23 can break up the clumps of slag powder in the silo, and the second scraper 25 can scrape off the slag powder adhering to the inner wall of the silo 11 during the rotation, ensuring the discharge effect. The screw rod 26, which extends to a certain depth in the discharge pipe 111, can continuously transport the slag powder from the upper end of the discharge pipe 111 to the lower end during the rotation, avoiding the slag powder from clogging the discharge pipe 111 and improving the discharge efficiency. After the discharge is completed, use the controller 4 to close the valve 12 and the motor 27.

[0035] If it is necessary to adjust the distance between the discharge pipe 111 and the ground, use multiple bolts 34 and nuts 341 to install four mounting blocks 33 sequentially on one side of the four support legs 32, so that the telescopic ends of the telescopic rods 36 face the ground. Use the terminal equipment to simultaneously control the extension of the four telescopic rods 36, causing the four casters 37 to move downwards. When the casters 37 contact the ground, continue to control the extension of the telescopic rods 36, causing the lower ends of the support legs 32 to separate from the ground. The distance between the discharge pipe 111 and the ground will then increase. Adjust until the distance is appropriate. When in the appropriate position, use the terminal device to simultaneously close all four telescopic rods 36, stopping their extension. Depress the brake wheel in the universal wheel 37, allowing the universal wheel 37 to provide support for the telescopic rods 36, support legs 32, storage structure 1, and related components in the screening and feeding mechanism 2. This allows the original receiving device to be connected to the discharge pipe 111 for corresponding discharge operations. Release the brake wheel in the universal wheel 37, allowing the universal wheel 37 to roll on the ground, thus adjusting the position of the device.

[0036] The components disclosed in this utility model for a storage device for producing slag powder, including controller 4, hopper 11, mounting shaft 113, valve 12, first top plate 13, second top plate 14, screen basket 21, support shaft 22, stirring rod 23, screw rod 26, motor 27, bracket 31, support leg 32, bolt 34, nut 341, mounting plate 35, telescopic rod 36, and caster wheel 37, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
