Abstract
Description
Technical Field
[0001] The utility model relates to a buffer material receiving device for a receiving hopper, belonging to the technical field of receiving hoppers. Background Art
[0002] The blast furnace's receiving hopper, where raw materials enter the furnace, is constantly subject to impact and friction from these materials. The hopper's lining, the primary component bearing the impact load and friction, is inevitably subject to some degree of damage. Therefore, the choice of material for the receiving hopper's receiving device, the first line of defense, is a matter of debate.
[0003] Common lining materials are mostly metal lining or ceramic lining. However, due to its high plasticity, metal lining is easily scratched and worn under the impact of materials and gradually fails due to oxidation by steam and air. Ceramic lining is easily subjected to alternating loads of high-frequency impact due to its low plasticity, forming cracks and reducing its service life. Utility Model Content
[0004] The technical problem to be solved by the present invention is to provide a buffering material receiving device for a receiving hopper in response to the above-mentioned prior art, so as to solve the problems of easy wear of low-hardness and high-plasticity metal liners and easy cracking of high-hardness and low-plasticity ceramic liners, thereby improving service life.
[0005] The technical solution adopted by the present invention to solve the above-mentioned problem is: a buffer material receiving device for a receiving hopper, comprising a supporting base, a material receiving tray is provided above the supporting base, a lining plate is laid in the material receiving tray to form a buffer material receiving tray; a plurality of buffer units are symmetrically arranged between the buffer material receiving tray and the supporting base, and the alternating stress generated by the impact of the material on the buffer material receiving tray will be absorbed by the buffer units.
[0006] The buffer units each include a vertically arranged buffer spring, and fixed supports are respectively provided at both ends of the buffer spring.
[0007] The receiving tray is respectively provided with U-shaped lining plates around its periphery, and the U-shaped lining plates are inserted on the top of the supporting base.
[0008] The lining plate and the U-shaped lining plate are respectively made of ceramics.
[0009] The two legs of the U-shaped lining plate are respectively provided with a slot.
[0010] The height of the U-shaped lining plate exposed from the support base is higher than the spring.
[0011] Compared with the existing technology, the advantages of the utility model are: a buffer material receiving device for a receiving hopper, which uses ceramic as the material of the lining plate and the U-shaped lining plate, and the buffer unit is fixedly installed under the buffer material receiving plate, so that the alternating stress generated by the impact of the material on the lining plate will be absorbed by the spring. The combination of the lining plate and the buffer spring ensures that the lining plate has sufficient wear resistance and can also avoid fatigue damage caused by high-frequency impact to a certain extent, thereby improving its service life.

[0014] Figure 3 for Figure 2 Schematic diagram of BB;
[0015] In the figure, 1 is the support base, 2 is the receiving tray, 3 is the U-shaped lining plate, 3.1 is the card slot, 4 is the fixed support, 5 is the buffer spring, and 6 is the lining plate. DETAILED DESCRIPTION
[0016] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0017] like Figure 1 、 2 As shown in Figures 3 and 4, a buffering material receiving device for a receiving hopper in this embodiment includes a grid-type support base 1, a material receiving tray 2 is provided above the support base 1, and a ceramic lining plate 6 is laid in the material receiving tray 2 to form a buffering material receiving tray. A plurality of buffer units are symmetrically arranged between the buffering material receiving tray and the support base 1. The alternating stress generated by the impact of the material on the buffering material receiving tray will be absorbed by the buffer units. The combination of the buffering material receiving tray and the buffer units ensures that the lining plate 6 has sufficient wear resistance and can also avoid fatigue damage caused by high-frequency impact to a certain extent.
[0018] The buffer units each include a vertically arranged buffer spring 5, with fixed supports 4 provided at each end. The top fixed support 4 is fixed to the bottom of the receiving tray 2, and the bottom fixed support 4 is fixed to the top of the support base 1. The buffer springs' shock absorption reduces fatigue damage to the liner 6, thereby reducing the occurrence of cracks in the liner 6.
[0019] The receiving tray 2 is surrounded by U-shaped ceramic linings 3, which effectively limit the range and frequency of the receiving tray 2's shaking. The two legs of the U-shaped lining 3 each have a slot 3.1, which is secured to the support base 1. The height of the U-shaped lining above the support base is slightly higher than the height of the spring, and the distance between the U-shaped lining and the receiving tray is relatively close, making it difficult for the material to become lodged in the spring. This prevents the spring from expanding or contracting, ensuring a cushioning effect. The U-shaped lining also provides excellent protection for the grille surrounding the drop point.
[0020] Before fixing the position of the receiving tray, the position of the raw material drop point must be determined. After determining the drop point, the receiving tray is welded to the grid at that position.
[0021] This application uses ceramic as the material for the lining plate and the U-shaped lining plate, and fixes the buffer unit under the buffer receiving tray so that the alternating stress generated by the impact of the material on the lining plate will be absorbed by the spring. The combination of the lining plate and the buffer spring ensures that the lining plate has sufficient wear resistance while also being able to avoid fatigue damage caused by high-frequency impact to a certain extent, thereby improving its service life.
[0022] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
