DETAILED DESCRIPTION

[0027] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0028] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0030] Traditional blast furnace top material bins mostly adopt a rectangular structure. This structure has exposed a series of problems in actual use, such as the particle size of the charge being destroyed during the vertical fall inside the bin, the charge causing serious fixed-point wear on the protective lining inside the bin, and the small space inside the bin making inspection and maintenance difficult.

[0031] To this end, the embodiment of the present invention discloses an inclined structure material warehouse, which can solve the problems of high operating cost and poor stability of existing blast furnaces to a certain extent, thereby extending the service life of the protective lining inside the material warehouse. The technical solution of this application is described in detail through specific embodiments below:

[0032] See also Figure 1 and Figure 2 In the first aspect of the present application, an inclined structure material warehouse is provided, which includes a warehouse cover 100, a guide plate 200, a material barrel 300 and a three-way flap valve box 400. The warehouse cover 100 is provided with a feed port 101, a mounting port 102 and a discharge port 103 which are connected in sequence. The discharge port 103 is lower than the feed port 101, and the discharge port 103 is arranged at an angle with the feed port 101, and a feed channel 104 is formed between the feed port 101 and the discharge port 103, and the mounting port 102 is located in the feed channel 104. The guide plate 200 is installed on the warehouse cover 100, and the guide plate 200 is located at the mounting port 102. The first end of the guide plate 200 is arranged toward the feed port 101, the second end of the guide plate 200 is arranged toward the discharge port 103, and the first end of the guide plate 200 is higher than the second end thereof. The material barrel 300 is installed on the storage cover 100, and the inlet of the material barrel 300 is communicated with the material outlet 103. The three-way flap valve box 400 is communicated with the outlet of the material barrel 300.

[0033] The inclined structure material bin disclosed in the present embodiment can form a first buffer for the descent of materials by setting a material guide plate 200, thereby preventing materials from directly colliding with the three-way flap valve box 400 and preventing materials from being damaged due to excessive impact force. At the same time, it can also prevent the material from violently impacting the barrel 300 and the three-way flap valve box 400, thereby preventing damage to the barrel 300 and the three-way flap valve box 400, thereby improving the stability of blast furnace production and reducing maintenance and operating costs.

[0034] In one embodiment, the discharge port 103 is arranged vertically to the feed port 101. The vertical arrangement can make more effective use of the vertical space, thereby reducing the overall volume of the material storage and making its structure more compact. The vertically arranged discharge port 103 and feed port 101 can more accurately control the flow speed and direction of the material by adjusting the angle and shape of the guide plate 200. This design helps prevent the material from being blocked or excessively accumulated during the transportation process, ensuring that the material can flow smoothly and continuously. At the same time, the vertically designed discharge port 103 and feed port 101 help reduce manufacturing costs and maintenance difficulties, while improving the reliability and service life of the equipment. Compared with the inclined arrangement, the vertical arrangement may reduce the friction and resistance of the material during the transportation process, allowing the material to reach the discharge port 103 faster.

[0035] In one embodiment, the inclination angle of the guide plate 200 is 5 to 25 degrees, and the inclination angle in this embodiment refers to the angle between the guide plate 200 and the horizontal direction after the storage cover 100 is installed. By setting the guide plate 200 at an inclination, on the one hand, after the material falls onto the guide plate 200, it can directly enter the barrel 300 along the discharge port 103 along the guide plate 200, thereby preventing the material from accumulating on the guide plate 200; on the other hand, the material can collide with the guide plate 200 to achieve the purpose of buffering.

[0036] The inclination angle of the guide plate 200 can be set to 10 degrees, 15 degrees or 25 degrees, etc. The speed of the material entering the barrel 300 is balanced by adjusting the angle of the guide plate 200. When the inclination angle of the guide plate 200 is large, the material is less buffered on the guide plate 200, but the material can pass through the guide plate 200 quickly, thereby avoiding accumulation on the guide plate 200; when the inclination angle of the guide plate 200 is small, the material is more buffered on the guide plate 200, but the speed of the material entering the barrel 300 from the guide plate 200 is slow, and there is a risk of material accumulation. This design provides flexibility, and the angle of the guide plate 200 can be adjusted according to the characteristics and processing requirements of the material to achieve the best processing effect. The inclined guide plate 200 design makes it difficult for the material to remain, reducing the workload of cleaning and maintenance. At the same time, the angle adjustment of the guide plate 200 is relatively simple, which is convenient for adjustment and optimization according to actual conditions.

[0037] In one embodiment, a dividing plate 500 is provided in the material barrel 300, and the dividing plate 500 is smaller than the material passage of the material barrel 300. The dividing plate 500 is designed to be smaller than the material passage of the material barrel 300. This means that the dividing plate 500 does not completely occupy the cross section of the material barrel 300, but leaves a certain space for the material to pass through. This design allows the material to be naturally distributed on both sides of the dividing plate 500 when passing through the material barrel 300, thereby achieving preliminary distribution of the material.

[0038] The main function of the material distributor 500 is to guide the flow direction of the material in the barrel 300 and promote the uniform distribution of the material. By adjusting the position, shape and size of the material distributor 500, the distribution ratio and conveying speed of the material can be flexibly controlled. In addition, the material distributor 500 can also slow down the flow rate of the material, prevent the material from falling too fast, and form a secondary buffer for the falling of the material.

[0039] The dividing plate 500 is usually made of wear-resistant and corrosion-resistant materials to ensure that it can maintain good performance and stability during long-term use. These materials include but are not limited to stainless steel, alloy steel, etc.

[0040] In one embodiment, the guide plate 200 has at least a portion extending to the discharge port 103, and the portion of the guide plate 200 extending to the discharge port 103 is smaller than the discharge port 103 to avoid blocking the discharge port 103, thereby ensuring that the discharge port 103 is large enough to allow the material to pass quickly and enter the barrel 300 below.

[0041] The guide plate 200 extends into the discharge port 103 to prevent the material from sliding down only along the side wall of the barrel 300, so that the material can perform free fall motion in the middle of the barrel 300. At the same time, the guide plate 200 allows the material to fall from the middle of the barrel 300 to ensure that the material can fall onto the dividing plate 500 as much as possible, so that the material forms a second buffer on the dividing plate 500.

[0042] In addition, the portion of the guide plate 200 extending to the discharge port 103 can ensure that the material can smoothly slide into the barrel 300 when being transported to the discharge port 103, without accumulation or blockage due to sudden changes in the discharge port 103. This design helps to reduce friction and resistance of the material during transportation and improve transportation efficiency.

[0043] In one embodiment, the portion of the guide plate 200 extending to the discharge port 103 is serrated, and the shape of the dividing plate 500 is adapted to the shape of the guide plate 200. The serrated guide plate 200 can make the material more dispersed in the barrel 300, avoid the material from falling in one place, and make the material more dispersed, thereby reducing the fixed point wear caused by the material on a single position.

[0044] See also Figure 1 and Figure 3In one embodiment, the material barrel 300 includes a first side wall 301 and a second side wall 302 that are arranged opposite to each other. The first side wall 301 is located below the material guide plate 200, and the second side wall 302 is located on the opposite side of the material guide plate 200. The material dividing plate 500 is spaced apart from the first side wall 301 and the second side wall 302, and the distance between the material dividing plate 500 and the first side wall 301 is greater than the distance between the material dividing plate 500 and the second side wall 302.

[0045] The material distributor plate 500 is spaced apart from the second side wall 302 and is further away from the first side wall 301. Such a layout enables the material to be more evenly distributed to different areas of the barrel 300 when passing through the material distributor plate 500. This helps to avoid excessive accumulation or poor flow of the material in a certain area, and ensures that the material sliding down from the guide plate 200 can basically contact the material distributor plate 500 for a second buffering.

[0046] By precisely controlling the distance between the dividing plate 500 and the first side wall 301 and the second side wall 302 , the distribution and flow path of the material can be optimized, thereby reducing the residence time of the material in the barrel 300 and improving the overall efficiency of material processing.

[0047] In one embodiment, the material distributor plate 500 has at least a part of overlapping in the height direction of the barrel 300. Generally, when the material moves on the material guide plate 200, the material close to the side of the pouring plate is compressed by the material above, and the material has a certain fluidity. Therefore, the closer the material is to the material guide plate 200, the lower the speed is. When the material directly in contact with the material guide plate 200 is separated from the material guide plate 200, the component speed in the horizontal direction is close to zero, so it may do vertical free fall motion. Through the above-mentioned structural design, it can be ensured that this part of the material can also be buffered for the second time on the material distributor plate 500.

[0048] In one embodiment, the material dividing plate 500 is arranged perpendicular to the material passage. This can prevent the material from colliding with the side wall of the material barrel 300 after colliding with the material dividing plate 500. The material rebounds after colliding with the material dividing plate 500 at a height perpendicular to the material barrel 300, and when it rebounds, it collides with the material above again, thereby reducing the descending speed of the material again.

[0049] In one embodiment, an observation hole is provided on the storage cover 100. The design of the observation hole enables the operator to observe or check the situation inside the storage cover 100 without opening the storage cover 100, so that the operator can more clearly understand the situation in the material warehouse. This facilitates the operator to make corresponding adjustments according to various situations.

[0050] In one embodiment, the shed cover 100 includes a first bottom plate 105, a second bottom plate 106, a top plate 107, a feed end plate 108, a baffle plate 109 and two side plates 110. The feed end plate 108 and the baffle plate 109 are relatively arranged at the two ends of the top plate 107, the feed end plate 108 is vertically arranged with the top plate 107, and the baffle plate 109 is inclined with the top plate 107 so that the bottom of the shed cover 100 is larger than its top. The top plate 107, the first bottom plate 105 and the second bottom plate 106 are arranged in sequence along the vertical direction. The first bottom plate 105 is connected to the feed end plate 108, the second bottom plate 106 is connected to the baffle plate 109, and the second bottom plate 106 and the first bottom plate 105 are spaced apart along the direction of the baffle plate 109 toward the feed end plate 108 to form the installation port 102. The feed port 101 is arranged on the feed end plate 108 to facilitate the entry of materials, and the discharge port 103 is arranged on the second bottom plate 106 to facilitate the discharge of materials. This design makes the material entry and exit process more orderly and efficient. Two side plates 110 are respectively arranged on both sides of the top plate 107 to enclose the feed channel 104. The observation hole is arranged on the baffle plate 109, and transparent glass is arranged at the observation hole so that the operator can view the feeding situation inside the storage cover 100 (such as whether there is material blockage, etc.) through the observation hole, so as to make corresponding adjustments in time.

[0051] See also Figure 1 and Figure 4 In one embodiment, the three-way flap valve box 400 includes an inlet and two outlets. The inlet of the three-way flap valve box 400 is connected to the outlet of the barrel 300, and the two outlets of the three-way flap valve box 400 are respectively connected to different structures for distributing materials. A material shifting plate 401 is also provided in the three-way flap valve box 400, and by rotating, the materials entering the three-way flap valve box 400 from the inlet can flow to the left outlet or the right outlet.

[0052] Through the above embodiments, the present application has the following beneficial effects or advantages: the inclined structure material warehouse disclosed in the present application realizes smooth transportation and efficient distribution of materials by optimizing the structural design. Specifically, the inclined design helps the materials to slide naturally under the action of gravity, reducing the accumulation and blockage phenomenon; the design of the guide plate 200 and the dividing plate 500 forms a graded drop of the material, and the buffering of the guide plate 200 and the dividing plate 500 effectively reduces the falling speed of the material, thereby reducing the impact force between the material and the material warehouse, and the guide plate 200 and the dividing plate 500 are used to reduce the vertical drop height of the material at a time, which is beneficial to protect the quality of the material and can also reduce the impact on the material warehouse; the flexible control of the three-way flap valve box 400 can meet the transportation requirements of different materials. In addition, the setting of the observation hole is convenient for the operator to observe and maintain. Therefore, the inclined structure material warehouse of the present invention has the advantages of simple structure, convenient operation, high transportation efficiency, and wide application range. With the help of the guide plate 200 and the dividing plate 500, it can also provide convenience for the internal inspection and maintenance of the material warehouse.

[0054] The furnace material storage and transportation efficiency disclosed in this embodiment is high. The reasonable angle setting of the material guide plate 200 and the material distribution plate 500 reduces the accumulation and blockage phenomenon, and improves the overall efficiency of the production line. The material transportation is stable and reliable, and the impact of the material on the barrel 300 and the three-way flap valve box 400 is weakened, reducing the equipment failure rate and maintenance cost. The setting of the observation hole facilitates observation and maintenance, and improves the reliability and service life of the equipment.
