Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of protective equipment for blanking chutes, and particularly relates to a protective device for a blanking chute for lithium ore roasting. Background Technique
[0002] In the lithium ore industry, the roasting of ore is a key production link. After this process, the roasted ore needs to be discharged from the blanking chute. Generally, in order to protect the blanking chute from various damages such as abrasion, high temperature, and material impact, the blanking chute is protected in the form of an inner lining of heat-insulating material, anchor bolts plus castable. However, in the existing blanking chutes for lithium ore roasting, there is still a relatively prominent problem, that is, during the discharging process of the roasted ore, the phenomenon of ore splashing often occurs. This splashing ore may not only damage the surrounding equipment but also seriously affect the operation safety. The splashing ore may cause harm to the on-site operators, posing a great safety hazard. In addition, some existing protective devices for blanking chutes are unreasonable in design. For example, due to the improper setting of the protective structure, the blanking channel becomes narrow. This narrowed channel will hinder the smooth flow of materials when the ore is discharged. This situation will not only reduce the blanking efficiency to a certain extent but also may cause a series of subsequent problems. For example, the reduction of the blanking efficiency may affect the progress of the entire production process, resulting in an extended production cycle and increased production costs. Content of the Utility Model
[0003] The main purpose of the utility model is to provide a protective device for a blanking chute for lithium ore roasting, which can effectively solve the problems in the background technique.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0005] A protective device for a blanking chute for lithium ore roasting includes a base load-bearing frame body. The middle part of the upper end of the base load-bearing frame body is fixedly connected in an inserted manner with a roasting heating box. The upper part of the outer surface of the roasting heating box is fixedly connected in an inserted manner with an upper connecting plate. A clamping groove is opened in the middle of the upper end of the upper connecting plate. Through holes are opened around the inner lower wall of the clamping groove. The upper connecting plate is clamped with left and right blanking protection structures through the clamping groove. A blanking anti-blocking structure is fixedly connected to the lower part of the inner wall of the roasting heating box. An electromagnetic valve is arranged on the lower part of the outer surface of the roasting heating box.
[0006] Preferably, the blanking protection structure includes a clamping plate. Threaded movable connections are provided around the upper end of the clamping plate with fastening screws. In the middle of the upper end of the clamping plate, a decentralized blanking chute is fixedly connected. At the upper end of the decentralized blanking chute, a blanking box is fixedly connected. At the upper left and upper right of the blanking box, blanking hoppers are fixedly connected. In the middle of the upper end of the decentralized blanking chute, a T-shaped baffle is fixedly connected. The upper part of the T-shaped baffle extends to the upper part of the blanking box, and the T-shaped baffle is located between the two blanking hoppers.
[0007] By adopting the above technical solutions: The decentralized blanking chute can be used to guide the falling of materials, enabling the materials to slide down dispersedly and evenly, reducing the concentrated impact of the materials. The blanking box receives the materials falling from the upper blanking hoppers and transfers them to the decentralized blanking chute for decentralized blanking. The T-shaped baffle is located between the two blanking hoppers, playing a role in separating and guiding the materials, preventing the direct impact and collision of the materials from the two blanking hoppers, and enabling the materials to enter the decentralized blanking chute more orderly.
[0008] Preferably, the opening area at the lower end of the decentralized blanking chute is smaller than the inner diameter area of the roasting heating box.
[0009] By adopting the above technical solutions: It can ensure that the materials falling from the blanking chute can fall more concentratedly into a specific area inside the roasting heating box, avoiding the over-dispersion of the materials resulting in uneven heating or affecting the roasting effect. At the same time, the smaller opening of the blanking chute also helps to control the falling speed and flow rate of the materials, making it better match the process conditions inside the roasting heating box, and improving the stability and efficiency of the entire production process.
[0010] Preferably, the clamping plate is clamped in the clamping groove. The clamping plate is detachably connected to the upper connecting plate through four fastening screws and four screw holes respectively. The decentralized blanking chute is located directly above the roasting heating box.
[0011] By adopting the above technical solutions: The clamping plate is clamped in the clamping groove, providing preliminary positioning and fixation, ensuring that the blanking protection structure can quickly align the position during installation. Pass the fastening screws through the screw holes to make a threaded detachable connection between the clamping plate and the upper connecting plate, achieving firm fixation, facilitating installation and disassembly, and being convenient for later maintenance and replacement. And the decentralized blanking chute is located directly above the roasting heating box, ensuring that the materials falling from the blanking chute can accurately fall into the roasting heating box, realizing the precise conveying of the materials, and ensuring the coherence and accuracy of the entire production process.
[0012] Preferably, the blanking anti-blocking structure includes a load-bearing column. Six reinforcing rods are fixedly connected in a circular array on the lower outer surface of the load-bearing column. At the upper end of the load-bearing column, a conical head is fixedly connected. Four material-dividing wedge-shaped baffles are fixedly connected to the outer surface of the conical head.
[0013] By adopting the above technical solution: The load-bearing column serves as the main support structure, bearing the weight of the entire blanking anti-blocking structure. The reinforcing rods are connected to the load-bearing column in an annular array, enhancing the stability of the load-bearing column and preventing it from tilting or shaking when bearing the impact of materials or other external forces. The conical head with its conical design helps to disperse the falling materials in all directions, reducing the concentrated accumulation of materials at a certain point. The distributing wedge-shaped baffle is fixed on the outer surface of the conical head, further dividing and guiding the materials, so that the materials are dispersed and fall more evenly, avoiding the blockage of the blanking channel.
[0014] Preferably, the six reinforcing rods are fixedly connected to the lower part of the inner wall of the roasting heating box together. The four distributing wedge-shaped baffles are distributed in an annular array, and the four distributing wedge-shaped baffles are flush with the upper end surface of the roasting heating box and are located directly below the decentralized blanking chute.
[0015] By adopting the above technical solution: The six reinforcing rods are fixedly connected to the lower part of the inner wall of the roasting heating box together, playing a role in firmly supporting the load-bearing column, capable of dispersing the pressure exerted by the materials above on the load-bearing column, and enhancing the stability of the entire blanking anti-blocking structure. The four distributing wedge-shaped baffles are distributed in an annular array. This uniform layout enables the falling materials to be evenly separated and guided from all directions. After the materials come into contact with the distributing wedge-shaped baffles, they will disperse along the inclined surface of the baffles, avoiding excessive concentration in a certain local area. The distributing wedge-shaped baffles are flush with the upper end surface of the roasting heating box, ensuring that the materials can smoothly enter from above the roasting heating box without getting stuck or piling up due to the height difference. At the same time, being located directly below the decentralized blanking chute ensures that the materials falling from the decentralized blanking chute can accurately land on the distributing wedge-shaped baffles, realizing the continuous, orderly, and uniform distribution of the materials, which helps to improve the smoothness and efficiency of the entire production process.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] 1. In the utility model, the clamping plate is detachably connected to the upper connecting plate through fastening screws, ensuring the firm installation of the blanking protection structure, not easily loosening during long-term use, guaranteeing the stability of lithium ore blanking. At the same time, it is convenient for subsequent maintenance, repair, or replacement, reducing the maintenance cost of the equipment. The T-shaped baffle is located between the two blanking hoppers, which can effectively separate the lithium ore materials falling from the two sides of the blanking hoppers, reduce direct collision, and lower the possibility of material splashing, improving the safety of the working environment. The decentralized blanking chute can make the materials fall more evenly, avoiding concentrated accumulation, which is beneficial for subsequent processing. In addition, the lower opening area of the decentralized blanking chute is smaller than the inner diameter area of the roasting heating box, enabling the lithium ore materials to fall relatively concentratedly into the roasting heating box, reducing the risk of blockage.
[0018] 2. In the present utility model, the load-bearing column is fixedly connected to the lower part of the inner wall of the roasting heating box through six reinforcing rods, greatly improving the stability of the blanking anti-blocking structure, capable of withstanding the impact of the falling lithium ore material and the pressure during long-term use, reducing the risk of structural deformation and damage. Four feeding wedge-shaped baffles distributed in an annular array are fixedly connected to the outer surface of the conical head, which can evenly disperse the falling lithium ore material to various parts of the roasting heating box, avoiding the material from concentrating in a certain area, making the material distribution more uniform, ensuring the smoothness of the blanking process, and improving the blanking and subsequent production efficiency.

[0027] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0028] A protection device for a lithium ore roasting feeding chute, including a base load-bearing frame 1. In the middle of the upper end of the base load-bearing frame 1, a roasting heating box 2 is inserted and fixedly connected. On the upper part of the outer surface of the roasting heating box 2, an upper connecting plate 3 is inserted and fixedly connected. In the middle of the upper end of the upper connecting plate 3, a card slot 4 is opened. Around the inner lower wall of the card slot 4, through screw holes 5 are opened. The upper connecting plate 3 is clamped with a left and right feeding protection structure 6 through the card slot 4. At the lower part of the inner wall of the roasting heating box 2, a blanking anti-blocking structure 7 is fixedly connected. At the lower part of the outer surface of the roasting heating box 2, a solenoid valve 8 is arranged.
[0029] In this embodiment, the feeding protection structure 6 includes a clamping plate 61. Around the upper end of the clamping plate 61, fastening screws 62 are threadedly and movably connected. In the middle of the upper end of the clamping plate 61, a decentralized feeding chute box 64 is fixedly connected. At the upper end of the decentralized feeding chute box 64, a blanking box 63 is fixedly connected. At the upper left part and the upper right part of the upper end of the blanking box 63, feeding hoppers 65 are fixedly connected. In the middle of the upper end of the decentralized feeding chute box 64, a T-shaped baffle 66 is fixedly connected. The upper part of the T-shaped baffle 66 extends to the upper part of the blanking box 63. The T-shaped baffle 66 is located between the two feeding hoppers 65. The opening area at the lower end of the decentralized feeding chute box 64 is smaller than the inner diameter area of the roasting heating box 2. The clamping plate 61 is clamped in the card slot 4. The clamping plate 61 is detachably connected to the upper connecting plate 3 respectively through four fastening screws 62 and four screw holes 5. The decentralized feeding chute box 64 is located directly above the roasting heating box 2.
[0030] Through the above solution: Materials enter the blanking box 63 from the blanking hoppers 65 on the left and right sides. The T-shaped baffle 66 separates the materials falling from the two blanking hoppers 65, avoiding direct collision of the materials, reducing the direct impact of lithium ore, and decreasing the possibility of splashing. Then the lithium ore enters the decentralized blanking chute 64, and after being dispersed, it falls from the lower opening thereof, which can disperse and guide the lithium ore, making the lithium ore fall more orderly and smoothly, reducing the probability of splashing. The clamping plate 61 is clamped in the clamping groove 4 and fixed to the upper connecting plate 3 through the fastening screw 62, ensuring the stability of the entire blanking protection structure 6. Since the decentralized blanking chute 64 is directly above the roasting and heating box 2 and the area of its lower opening is smaller than the inner diameter area of the roasting and heating box 2, there is a certain space limitation when the lithium ore falls, reducing the range of outward splashing, so that the lithium ore can fall into the roasting and heating box 2 relatively concentratedly.
[0031] In this embodiment, the blanking anti-blocking structure 7 includes a load-bearing column 71. Six reinforcing rods 72 are fixedly connected in a circular array on the lower part of the outer surface of the load-bearing column 71. The upper end of the load-bearing column 71 is fixedly connected with a conical head 73. Four material-distributing wedge-shaped baffles 74 are fixedly connected to the outer surface of the conical head 73. The six reinforcing rods 72 are jointly fixedly connected to the lower part of the inner wall of the roasting and heating box 2. The four material-distributing wedge-shaped baffles 74 are distributed in a circular array, and the four material-distributing wedge-shaped baffles 74 are flush with the upper end surface of the roasting and heating box 2 and are directly below the decentralized blanking chute 64.
[0032] Through the above solution: The lithium ore falls from the decentralized blanking chute 64 and just lands on the material-distributing wedge-shaped baffle 74 that is directly below it and flush with the upper end surface of the roasting and heating box 2. Since the four material-distributing wedge-shaped baffles 74 are distributed in a circular array, they can quickly disperse and guide the falling lithium ore, avoiding blockage of the lithium ore at a certain place, thus keeping the blanking channel unobstructed and accelerating the blanking speed. The load-bearing column 71 is firmly fixed to the lower part of the inner wall of the roasting and heating box 2 through the six reinforcing rods 72, providing stable support for the upper conical head 73 and the material-distributing wedge-shaped baffle 74. The design of the conical head 73 enables the lithium ore to disperse around, reducing the centralized accumulation of materials in the center. Therefore, through the combined action of the material-distributing wedge-shaped baffle 74 and the conical head 73, the effect of improving the blanking speed is achieved.
[0033] It should be noted that the utility model is a protective device for a lithium ore roasting discharge chute. During use, the lithium ore material is firstly fed into the discharge hoppers 65 on the left and right sides of the upper end of the discharge box 63. The T-shaped baffle 66 can separate the lithium ore materials in the discharge hoppers 65 on both sides to avoid direct collision and splashing of the lithium ore materials. Then the lithium ore materials enter the dispersed discharge chute 64 and fall from the lower opening after being dispersed. Since the lower opening area of the dispersed discharge chute 64 is smaller than the inner diameter area of the roasting and heating box 2, the lithium ore materials can fall into the roasting and heating box 2 relatively concentratedly. A material falling prevention structure 7 is provided at the lower part of the inner wall of the roasting and heating box 2. Four material dividing wedge baffles 74 distributed in a circular array and flush with the upper end surface of the roasting and heating box 2 can receive the falling lithium ore materials and disperse and guide the lithium ore quickly and evenly. The conical head 73 can further assist the lithium ore to diffuse around and reduce the accumulation of materials in the center. The six reinforcement rods 72 ensure the stability of the load-bearing columns 71 and the entire material falling prevention structure 7. Therefore, with the mutual coordination of the entire accessories, the accumulation and blockage of lithium ore materials in the falling process are avoided, and the effect of increasing the material discharge speed is achieved.
[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
