AI Technical Summary
The existing vertical furnace ball round roller screen is made of scrap belts, which are easy to bulge and deform, and have a short service life, resulting in poor quality of material dropping and growing balls, lower drop strength, and large return volume.
A new type of feeding lining plate was designed, including a base fixed steel plate and a removable nylon lining plate body. The nylon lining plate body is an isosceles trapezoidal structure, which is fixed to the base steel plate by screws and nuts to ensure the stability and durability of the lining plate.
This design extends the service cycle of the feeding plate, avoids belt bulge and deformation, ensures smooth discharge, improves the drop strength and quality of the raw ball, reduces the return, and reduces the labor intensity of the workplace.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metallurgy, and particularly relates to a new type of receiving lining plate at the discharging opening of a circular roller screen for shaft furnace pelletizing. Background Art
[0002] At present, the receiving lining plate at the discharging opening of the circular roller screen for shaft furnace pelletizing in the ironmaking plant is made of waste belts. This kind of lining plate has many disadvantages. For example, the belt is easy to bulge, the service life is short, it is easy to deform, and after deformation, gaps are generated and materials are easy to fall off. It requires operators to frequently remove and clean materials. In addition, after the belt bulges, the receiving plate adheres to materials, resulting in poor discharging of green pellets, poor quality of green pellets, low drop strength, and a large amount of green pellet return material. Content of the Utility Model
[0003] In view of the above technical problems, the utility model provides a new type of receiving lining plate at the discharging opening of a circular roller screen for shaft furnace pelletizing.
[0004] In order to achieve the above purpose, the technical solution of the utility model is specifically as follows:
[0005] A new type of receiving lining plate at the discharging opening of a circular roller screen for shaft furnace pelletizing, comprising:
[0006] A bottom fixed steel plate, arranged at the discharging opening of the circular roller screen;
[0007] A nylon lining plate body, detachably installed on the bottom fixed steel plate.
[0008] The nylon lining plate body is an isosceles trapezoid structure that can be mutually adapted to the discharging opening of the circular roller screen. Two mounting holes are horizontally arranged at the upper base of the isosceles trapezoid structure, and three mounting holes are horizontally arranged at the lower base; vertical screws corresponding to the positions of the mounting holes are arranged on the bottom fixed steel plate, so that after the screws on the bottom fixed steel plate are inserted into the mounting holes on the nylon lining plate body, they can be fixed by nuts.
[0009] The thickness of the nylon lining plate body is 30 mm, the length of the lower base is 1200 mm, the length of the upper base is 600 mm, the height is 420 mm, the diameter of the mounting hole is 18 mm, the horizontal distance between each mounting hole is 400 mm, and the vertical distance is 150 mm.
[0010] A sinking hole with a diameter of 30 mm is also arranged on the mounting hole to facilitate the entry of the nut.
[0011] The beneficial effects of the present utility model are as follows: The present utility model is durable, does not deform or bulge, achieving the effect of long-term use, greatly extending the service life of the material receiving plate, solving the problem of belt material dropping, reducing the labor intensity of the post workers, reducing the operation frequency, and ensuring the safety of the workers. The surface of this circular roller screen material receiving plate is smooth and flat, the green balls are discharged smoothly without sticking to the material, improving the dropping strength and quality of the green balls, reducing the return material, and lowering the return ore of pellet ore. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] The following further describes in detail the specific embodiments of the present utility model with reference to the drawings.
[0013] Figure 1 It is a schematic structural diagram of the present utility model.
[0014] Figure 2 It is an installation schematic diagram of the present utility model. SPECIFIC EMBODIMENTS
[0015] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0016] As Figure 1 and Figure 2 shown, a new type of receiving lining plate at the feeding port of a circular roller screen for shaft furnace pelletizing includes: a bottom fixing steel plate 2, which is arranged at the feeding port of the circular roller screen; a nylon lining plate body 1, which is detachably installed on the bottom fixing steel plate 2.
[0017] As Figure 1 and Figure 2 shown, the nylon lining plate body 1 is an isosceles trapezoid structure that can be adapted to the feeding port of the circular roller screen. There are two mounting holes horizontally arranged at the upper base of the isosceles trapezoid structure, and three mounting holes horizontally arranged at the lower base. There are vertical screws 3 on the bottom fixing steel plate 2 corresponding to the positions of the mounting holes. After the screws 3 on the bottom fixing steel plate 2 are inserted into the mounting holes on the nylon lining plate body 1, they can be fixed by nuts. The thickness of the nylon lining plate body 1 is 30 mm, the length of the lower base is 1200 mm, the length of the upper base is 600 mm, the height is 420 mm, the diameter of the mounting holes is 18 mm, the horizontal distance between each mounting hole is 400 mm, the vertical distance is 150 mm, and there is also a sinking hole with a diameter of 30 mm on the mounting hole to facilitate the entry of the nut.
[0018] In actual on-site operations of the utility model, the screw rods 3 on the bottom fixing steel plate 2 are correspondingly inserted into the mounting holes on the nylon liner body 1 and fixed by tightening nuts. Then, it is adaptively installed at the discharge opening of the rotary screen. The bottom fixing steel plate 2 of the utility model supports the nylon liner body 1, making the nylon liner body 1 durable, without deformation or bulging, achieving the effect of long-term use. Due to its material characteristics, the surface of the nylon liner body 1 is smooth and flat, the green pellets are discharged smoothly, without sticking to the material, and the return material is reduced.
[0019] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
