Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a steel raw material vibrating screen. Background Art

[0002] During the preparation stage of raw materials, steel mills will screen and grade various raw materials (such as iron ore, coke, sintered ore, pelletized ore, etc.) to ensure that the raw materials have uniform particle size and are suitable for the subsequent smelting process. At present, linear vibrating screens (also known as vibrating screens) are mostly used for screening and grading steel raw materials.

[0003] As in the prior art, the patent with the patent authorization announcement number CN220143998U discloses a linear vibrating screen, wherein a screen plate is installed on the inner side of the screen box, a feed hopper is fixed on the top of one end of the screen box, a discharge hopper is installed on the other end of the screen box, a discharge pipe is fixed on the bottom of the other end of the screen box, a mounting frame is provided at the bottom of the screen box, connecting plates are symmetrically fixed on both sides of the screen box, a connecting spring is installed between the bottom end surface of the connecting plate and the top end surface of the mounting frame, a vibration motor is installed in the middle of the bottom end surface of the screen box, and a functional component is provided at one end of the inner side of the screen box; through the designed functional component, it is convenient to avoid the accumulation of materials on one end of the screen plate after passing through the feed hopper, so that the materials can be moved to the screen plate through the guide plate for mobile screening, which is convenient to improve the screening efficiency of the materials and improve the functionality; through the designed material blocking component, it is convenient to close one end of the discharge hopper, so that the unscreened materials can be moved to the inside of the discharge hopper through the sieve plate for collection.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-6 A steel raw material vibrating screen comprises a vibrating screen body 1, a cover plate 2 is connected to the top of the vibrating screen body 1, a connecting pipe 9 is fixedly connected to one side of the vibrating screen body 1, a blower 3 is fixedly connected to the middle position of the cover plate 2, an air guide pipe 4 is fixedly connected to the upper end of the blower 3, an air inlet of the blower 3 is connected to the interior of the vibrating screen body 1, an air outlet of the blower 3 is connected to the air guide pipe 4, and an end of the air guide pipe 4 away from the blower 3 is connected to the connecting pipe 9.

[0024] In the steel raw material vibrating screen of the utility model, when the vibrating screen body 1 is working, the cover plate 2 will seal the upper end of the vibrating screen body 1, so as to prevent dust from being directly discharged into the atmosphere. At the same time, the end of the connecting pipe 9 away from the blower 3 is connected to the external dust removal equipment, and then the air containing dust is introduced into the external dust removal equipment through the blower 3, the air guide pipe 4 and the connecting pipe 9, so as to reduce the pollution of dust to the environment. If the dust removal equipment is not purchased, a certain amount of clean water can be injected into the connecting pipe 9 (there is no clear requirement for the amount of clean water, as long as the connecting pipe 9 is not completely blocked). In the case of a U-shaped pipe, as much clean water as possible can be injected), since the connecting pipe 9 is a U-shaped pipe, the clean water will be at the lower end of the connecting pipe 9 (i.e. the U-shaped turn of the connecting pipe 9), and the air containing dust blown down from the upper end of the connecting pipe 9 will turn at this position. At this time, the air will come into contact with the clean water, so that the dust will be dissolved in the clean water, thereby reducing the dust content in the air. In addition, in the utility model, the structure of the vibrating screen body 1 is similar to a linear vibrating screen structure disclosed in the patent authorization announcement number CN220143998U, so it will not be elaborated on here.

[0025] like Figure 1 , Figure 2 and Figure 6 As shown, a slide groove 5 is provided at the top and bottom of the air guide pipe 4 near one end of the connecting pipe 9, a slider 6 is slidably connected inside the slide groove 5, a sleeve 8 is fixedly connected to the outer side of the slider 6, and the sleeve 8 matches the connecting pipe 9.

[0026] Specifically, after the air duct 4 is aligned with the connecting tube 9, the sleeve 8 can be pushed toward the connecting tube 9 so that the sleeve 8 is sleeved on the connecting tube 9, thereby reinforcing the connection between the air duct 4 and the connecting tube 9 and avoiding misalignment between the air duct 4 and the connecting tube 9.

[0027] like Figure 1 and Figure 2 As shown, an elastic member 7 is fixedly connected to one side of the sliding block 6 away from the connecting pipe 9 , and the other end of the elastic member 7 is fixedly connected to the end of the sliding groove 5 .

[0028] Specifically, the slider 6 is pushed by the elastic member 7 to prevent the slider 6 from sliding in a direction away from the connecting tube 9 , so that the sleeve 8 is separated from the connecting tube 9 , causing the sleeve 8 to lose its restricting effect.

[0029] like Figure 4 and Figure 5 As shown, a positioning block 10 is fixedly connected to the bottom of the cover plate 2 , and a positioning groove 11 matching the positioning block 10 is formed on the top of the vibration screen body 1 .

[0030] Specifically, the cover plate 2 is restricted by the positioning block 10 and the positioning groove 11, so that the cover plate 2 can be connected to the vibration screen body 1 and can be easily disassembled.

[0031] like Figure 4 and Figure 5 As shown, a support plate 12 is fixedly connected to one side of the cover plate 2 close to the connecting pipe 9 , and a support groove 13 matching with the support plate 12 is provided on one side of the upper end of the vibration screen body 1 close to the connecting pipe 9 .

[0032] Specifically, the contact area between the vibration screen body 1 and the cover plate 2 is increased by the support plate 12 and the support groove 13 , thereby improving the stability of the connection between the cover plate 2 and the vibration screen body 1 .

[0033] like Figure 4 and Figure 5 As shown, a socket 14 connected to the support groove 13 is provided on one side of the upper end of the vibration screen body 1, and an insert block 15 is slidably connected inside the socket 14. The top of the insert block 15 passes through the support plate 12 and extends to the outside of the vibration screen body 1, and the top of the insert block 15 is fixedly connected to a connecting plate 16.

[0034] Specifically, after the cover plate 2 is connected to the vibration screen body 1, the insert block 15 can be inserted into the insertion hole 14, so as to restrict the cover plate 2 and prevent the cover plate 2 from automatically expanding due to vibration or other reasons.

[0035] like Figure 4 and Figure 5 As shown, a handle 17 is fixedly connected to the top of the connecting plate 16, and the handle 17 is an inverted U-shaped arrangement. The handle 17 is provided to make the connecting plate 16 and the inserting block 15 more labor-saving and convenient when being inserted and pulled.

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