Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a high-efficiency vibrating screen for ironmaking equipment. Background Art

[0002] The main function of the vibrating screen in the ironmaking process is to screen and grade the iron ore. It can effectively remove large particles of impurities in the iron ore and improve the quality of the iron ore. At the same time, the vibrating screen can also grade the material and screen it according to the particle size to the next production line to achieve more refined production activities.

[0003] The patent with the announcement number CN211914530U currently discloses a high-efficiency vibrating screen for ironmaking equipment, and its technical points are: the high-efficiency vibrating screen for ironmaking equipment includes a body, a feed port, a discharge port, a forward and reverse motor, a fixed seat, a vibration motor, a control switch and a support leg. A quick dredging device is set at the left end of the top of the body, and the driving mechanism is started by the control switch. The driving mechanism drives the movable rod to move downward in the shell, and the movable rod drives the pressure plate to move downward synchronously, so that the pressure plate extends into the feed port to press the material into the body. A driving mechanism is set in the middle of the shell, and the motor is started by the control switch. The motor drives the movable block to move through the rotating shaft, and the movable block drives the movable rod to move through the slider. The device is easy to use and simple to operate, improves labor productivity and improves working conditions at the same time, and effectively solves the problems of poor dredging effect of the feed port and poor driving effect of the movable rod of the traditional high-efficiency vibrating screen for ironmaking equipment.

[0004] Although the above technology effectively solves the problems of poor dredging effect of the feed port and poor driving effect of the movable rod of the high-efficiency vibrating screen used in traditional iron-making equipment, with the use of the vibrating screen, the material will block the screen, causing the efficiency of the screen to decrease. We set up a cleaning device under the screen, and the cleaning roller rolls inside to clean the blocked material. Due to the interaction between the cleaning roller and the screen and the blocked material, it will also cause damage. The staff needs to replace the cleaning equipment, and the closed box is not convenient for replacing the cleaning roller, which leads to poor cleaning effect and further reduces the efficiency of the vibrating screen. Utility Model Content

[0005] The utility model aims to solve the problems existing in the prior art and proposes a high-efficiency vibrating screen for ironmaking equipment, which can reduce the loss of cleaning equipment and reduce the use efficiency of the vibrating screen.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A high-efficiency vibrating screen for ironmaking equipment comprises a vibrating screen body and a cleaning device fixedly connected to the inner wall of the vibrating screen body, the cleaning device comprises a driving mechanism and a cleaning roller fixedly connected to the inner wall of the vibrating screen body, a rear cover is hinged at the rear of the vibrating screen body, a lock is connected to the rear cover, and the rear cover and the vibrating screen body are connected by the lock.

[0009] Preferably, the driver may be a motor, and the motor may be a forward and reverse motor.

[0010] Preferably, the cleaning roller includes an outer shell, a rotating shaft passing through the center of the outer shell, and an insertion rod fixed to the surface of the outer shell, the upper end of the insertion rod is slightly higher than the upper surface of the sieve hole, and the surface of the outer shell is provided with a circular groove, and both ends of the rotating shaft are rotatably connected to the sliding seat.

[0011] Preferably, the housing is composed of two semicircular shells, the outer walls of the semicircular shells are provided with threaded holes, and the two semicircular shells are connected into a whole by bolts.

[0012] Preferably, two ends of the bottom surface of the strip slideway are provided with leaking openings communicating with the slide groove.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. This type of iron-making equipment uses a high-efficiency vibrating screen, and the cleaning equipment can be changed according to the number of screens through the cleaning equipment set in the vibrating screen. In the iron-making process, we need to screen and grade the iron ore. The screen and the cleaning equipment are one-to-one. For the screen that needs to be cleaned, we only need to open the corresponding cleaning equipment. There is no need to open all the cleaning equipment, which reduces the loss of the cleaning equipment.

[0015] 2. This kind of iron-making equipment uses a high-efficiency vibrating screen with a hinged rear cover and an outer shell composed of two semicircular shells. When we replace the cleaning roller, we only need to release the restriction of the lock and pull up the rear cover to see the inside of the rotating screen. The outer shell can be disassembled by unbolting the bolts. The damaged cleaning roller can be quickly replaced to ensure the cleaning of the screen, thereby further improving the working efficiency of the vibrating screen.

[0016] 3. This kind of high-efficiency vibrating screen for iron-making equipment has leaks at both ends of the strip slide. During the sliding process of the sliding seat, the powder material falling in the sliding device can be cleaned. When the sliding seat slides to both ends, the powder material can leak down through the leak to avoid long-term accumulation affecting the sliding of the sliding seat, thereby increasing the use efficiency of the cleaning equipment and further improving the efficiency of the vibrating screen.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See also Figure 1-Figure 7A high-efficiency vibrating screen for ironmaking equipment comprises a vibrating screen body 1 and a cleaning device 2 fixedly connected to the inner wall of the vibrating screen body 1, the cleaning device 2 comprises a driving mechanism 3 and a cleaning roller 4 fixedly connected to the inner wall of the vibrating screen body 1, a rear cover is hinged at the rear of the vibrating screen body 1, a lock buckle 5 is connected to the rear cover, and the rear cover and the vibrating screen body 1 are connected through the lock buckle 5.

[0027] The utility model is similar to the existing vibrating screen structure, such as the patent with announcement number CN211914530U discloses a high-efficiency vibrating screen for ironmaking equipment. The main improvement of the utility model is to facilitate the replacement of the cleaning roller 4 of the vibrating screen. Figures 1 to 7 As shown, when cleaning the screen and replacing the roller of a high-efficiency vibrating screen for iron-making equipment, the staff starts the driving mechanism 3 to slide the cleaning roller 4. At this time, the insertion rod 404 on the outer shell 401 can push out the blocked material, so that the screen is cleaned. Long-term use of the cleaning equipment 2 will damage the cleaning roller 4. The staff can replace the outer shell 401 of the cleaning roller 4 by opening the front cover of the vibrating screen, so as to ensure the cleanliness of the vibrating screen mesh and improve the efficiency of the vibrating screen.

[0028] like Figure 1 and Figure 4 As shown, the driving mechanism 3 includes two parallel bar slides 301, the side walls of the bar slides 301 are provided with slide grooves, a threaded rod 302 is arranged in the slide grooves, one end of the slide grooves is fixedly connected to a driver 303, one end of the threaded rod 302 is connected to the output end of the driver 303, and the other end is rotatably connected to the inner wall of the slide groove, the upper part of the bar slide 301 is fixedly connected to a fixing plate 6 for connecting to the inner wall of the vibration screen body 1, a sliding seat 304 is threadedly connected to the threaded rod 302, and both ends of the cleaning roller 4 are rotatably connected to the sliding seat 304.

[0029] Specifically, two parallel strip slideways 301 allow the cleaning roller 4 to slide more smoothly along the sliding seat 304 under the screen. The arrangement of multiple cleaning devices 2 is based on the number of screens. When we clean the screen, we only need to start the cleaning device 2 under the screen.

[0030] like Figure 6 and Figure 7 As shown, the cleaning roller 4 includes a shell 401, a rotating shaft 402 passing through the center of the shell 401, and an insertion rod 404 fixed to the surface of the shell 401. The upper end of the insertion rod 404 is slightly higher than the upper surface of the sieve hole. A circular groove 403 is opened on the surface of the shell 401, and both ends of the rotating shaft 402 are rotatably connected to the sliding seat 304.

[0031] Specifically, when cleaning the screen, the plug rod 404 is inserted into the screen hole to push out the blocked material, and the cleaning roller 4 can also be driven to rotate through the caries effect between the plug rod 404 and the screen hole. The material of the plug rod 404 is steel wire, and the steel wire has a certain bending and rebound ability. When the plug rod 404 cannot push out the blocked material, the plug rod 404 itself can bend appropriately, which can effectively prevent the cleaning roller 4 from getting stuck on the screen.

[0032] like Figure 6 and Figure 7 As shown, the housing 401 is composed of two semicircular shells, the outer walls of the semicircular shells are provided with threaded holes, and the two semicircular shells are connected into a whole by bolts.

[0033] Specifically, when the cleaning roller 4 needs to be replaced after being damaged, the staff releases the restriction of the lock 5, opens the back cover, unscrews the bolts on the outer shell 401 of the cleaning roller 4, and then removes the outer shell 401. Similarly, the new cleaning roller 4 can be replaced by following the opposite action, which is more convenient and time-saving.

[0034] like Figure 5 and Figure 7 As shown, the driver 303 may be a motor, and the motor is a forward and reverse motor, and leaks 7 communicating with the slide grooves are provided at both ends of the bottom surface of the strip slide 301 .

[0035] Specifically, the sliding seat 304 can reciprocate in the horizontal direction under the action of the driver 303. When moving, the sliding seat 304 can push away the powdered material at the bottom of the driving mechanism 3 and let it leak downward through the opened leakage port 7 to avoid material accumulation and thus hinder the operation of the driving mechanism 3.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
