Description

Technical Field

[0001] This utility model patent belongs to the field of metallurgical technology, specifically relating to an auxiliary cooling and crushing mechanism for unloading manganese ore sintering ore cars. Background Technology

[0002] Iron-manganese ore is a common low-grade complex iron ore resource. Currently, the most effective method is to smelt it in a blast furnace through agglomeration to produce manganese-rich slag. Sintering is the main agglomeration method for iron-manganese ore. The sintering trolley is the main operating component of the sintering machine. Its main function is to form a rotating chain between the head and tail wheels of the sintering machine. It receives the sintering mixture in the upper horizontal section, and after preheating, ignition, sintering, cooling, and turning, it returns to the head wheel, forming a transmission cycle to achieve the purpose of sintering the material.

[0003] For example, a trolley for sintering manganese ore, disclosed in Chinese Patent (CN220771849U), includes: a trolley frame, baffles, and a grate. The baffles are vertically connected to both ends of the trolley frame, and at least one air-blocking platform is installed on each baffle. The top surface of the air-blocking platform is vertically connected to the baffle. The grate is installed in the cavity formed by the trolley frame and the baffles. The grate corresponding to the bottom of the air-blocking platform has a horizontal structure, while the middle grate has a corrugated structure. Multiple ventilation chambers are continuously formed at the bottom of the middle grate, and ventilation holes are provided on the grate. This device solves the problem of incomplete combustion and low combustion efficiency of the bottom ore. However, after research, the inventors found that the above-mentioned sintering device still has the following defects in application: 1. The preheating and ignition and sintering processes occur at the head and middle of the sintering machine, while the cooling process occurs at the tail of the sintering machine. The current cooling is achieved through natural air cooling, which has low cooling efficiency. Furthermore, the material on the upper layer of the trolley cools and clumps first, resulting in low heat dissipation efficiency for the material in the middle and lower layers of the trolley. 2. At the same time, because the trolley is used for discharging material in sections, large-scale clumping of material can cause material to be carried along or difficult to separate when the trolley is divided, thus affecting the material turning efficiency.

[0004] Therefore, this utility model proposes an auxiliary cooling and crushing mechanism for unloading manganese ore sintering ore cars. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes an auxiliary cooling and crushing mechanism for unloading manganese ore sintering cars. This mechanism eliminates the need for a drive structure, saving energy consumption. It can break up the material that has cooled and clumped on the top layer of the sintering car through the crushing and dismantling rollers, facilitating segmented unloading of the car in subsequent stages. It also reduces dust generated during crushing.

[0006] To achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: an auxiliary cooling and crushing mechanism for unloading manganese ore sintering cars, including a sintering trolley, a track, an observation platform, a base column, a crushing and dismantling roller, and a water cooling mechanism. Several sintering trolleys are continuously and closely mounted on the track. An observation platform is fixedly installed on the rear upper part of the several sintering trolleys through the base columns on both sides of the sintering trolleys. A mounting seat is provided on the base column on the lower front side of the observation platform. A crushing and dismantling roller that can crush and dismantle agglomerated materials is rotatably mounted on the mounting seat. The crushing and dismantling roller is located on the upper side of the agglomerated material, and the crushing and dismantling structure on the crushing and dismantling roller can be inserted into the agglomerated material and rolls as the trolley moves backward. The water cooling mechanism is installed on the frame on the upper front side of the observation platform.

[0007] Preferably, the mounting base is fixedly installed on the inner side of the base columns on both sides of the sintering trolley.

[0008] Preferably, the mounting base is movably mounted on the inner side of the base columns on both sides of the sintering trolley via a lifting structure.

[0009] Preferably, the lifting structure further includes a limiting slide groove, a lead screw, a base, a rotating handle, and a screw hole. The limiting slide groove is located inside the base column, and the base is fixedly installed on the lower base column outside the limiting slide groove. The upper and lower ends of the lead screw are rotatably installed in the observation platform and the base, respectively, with the upper end of the lead screw extending from the upper side of the observation platform. The top of the lead screw is connected to a rotating handle. The screw hole corresponding to the external thread of the lead screw is located in the mounting base, and the mounting base is installed on the lead screw through the screw hole.

[0010] Preferably, the crushing and dismantling roller further includes a rolling spindle and a crushing and dismantling structure, wherein the rolling spindle is provided with the crushing and dismantling structure on the outer side above the sintering trolley.

[0011] Preferably, the crushing and dismantling structure further includes a material distribution disc, a dismantling insert plate, and a crushing plug. The material distribution discs evenly divide the rolling spindle into several material distribution compartments from left to right. Each compartment is evenly welded with several dismantling insert plates, and the dismantling insert plates divide the compartment into several fan-shaped dismantling compartments. The outer side of each material distribution disc is evenly equipped with several crushing plugs.

[0012] Preferably, the water cooling mechanism further includes a water supply main, a spray head, a water pump, and a water storage tank. The water supply main is connected to the water storage tank via the water pump, and the spray head is connected to the lower side of the water supply main and located above the sintering trolley.

[0013] The beneficial effects of this utility model are: The crushing roller of this mechanism can roll as the trolley moves backward after being inserted into the agglomerated material, thereby achieving rolling crushing. It does not require a drive structure, saving energy consumption. The crushing roller can also break up the material that has cooled and agglomerated on the top layer of the sintering trolley, so that the trolley can dump material in sections. At the same time, the crushed material can facilitate the accelerated cooling of the middle layer of material. The water cooling mechanism is designed to accelerate the cooling of the sintered material and reduce the dust generated during crushing. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0016] like Figures 1 to 2 As shown, the prior art in this embodiment has the following problems: After research by the inventors, it was found that the above-mentioned sintering device also has the following defects in application: the preheating and ignition and sintering processes occur at the head and middle of the sintering machine, while the cooling process occurs at the tail of the sintering machine. The current cooling is achieved by natural air cooling, which has low cooling efficiency. Moreover, the material on the upper layer of the trolley usually cools and clumps first, resulting in low heat dissipation efficiency of the material in the middle and lower layers of the trolley. At the same time, because the trolley is segmented for material pouring, large-scale clumps of material can cause material to be carried along or difficult to separate when the trolley is segmented, thus affecting the material turning efficiency.

[0017] Therefore, the inventor provides an auxiliary cooling and crushing mechanism for unloading manganese ore sintering ore cars, including a sintering trolley 1, a track 2, an observation platform 3, a base column 4, a crushing and dismantling roller, and a water cooling mechanism. Several sintering trolleys 11 are continuously and closely mounted on the track 2. The observation platform 3 is fixedly installed on the rear upper part of the several sintering trolleys 1 through the base columns 4 on both sides of the sintering trolley 1. The base column 4 on the lower front side of the observation platform 3 is provided with a mounting seat 5. A crushing and dismantling roller that can crush and dismantle agglomerated materials is rotatably mounted on the mounting seat 5. The crushing and dismantling roller is located on the upper side of the agglomerated material, and the crushing and dismantling structure on the crushing and dismantling roller can be inserted into the agglomerated material and roll as the trolley moves backward. The water cooling mechanism is installed on the frame (not shown in the figure) on the upper front side of the observation platform 3.

[0018] Its effects are as follows: the mechanism does not require a drive structure, saving energy consumption. It can break up the material that has cooled and clumped on the top layer of the sintering trolley 1 through the crushing and dismantling roller, so that the trolley can dump the material in sections in the future. At the same time, it can reduce the dust generated during crushing.

[0019] In this embodiment, the mounting base 5 is fixedly installed on the inner side of the base columns 4 on both sides of the sintering trolley 1. This structure requires the amount of material in the sintering trolley 1 to be estimated in advance to ensure that the crushing and dismantling structure under the crushing and dismantling roller can be inserted into the material.

[0020] In this embodiment, the mounting base 5 is movably mounted on the inner side of the base columns 4 on both sides of the sintering trolley 1 via a lifting structure (not shown in the figure). This structure eliminates the need to estimate the amount of material to be received in the trolley in advance, and the contact height between the crushing and dismantling roller and the material in the trolley can be adjusted through the lifting structure at the beginning of each sintering.

[0021] In this embodiment, the lifting structure further includes a limiting groove, a lead screw, a base, a rotating handle, and a screw hole. The limiting groove is located inside the base column 4, and the base is fixedly installed on the lower base column 4 outside the limiting groove. The upper and lower ends of the lead screw are rotatably installed in the observation platform 3 and the base, respectively, with the upper end of the lead screw extending from the upper side of the observation platform 3. The top of the lead screw is connected to a rotating handle. The screw hole corresponding to the external thread of the lead screw is located in the mounting seat 5, and the mounting seat 5 is installed on the lead screw through the screw hole. When this structure is used, the operator can first judge the thickness of the material agglomeration, and then rotate the lead screw by rotating the handle. By controlling the lifting of the mounting seat 5, the contact height between the crushing and dismantling roller and the material in the vehicle can be adjusted, thereby ensuring that the agglomerated material can be fully crushed (crushed) and dismantled.

[0022] In this embodiment, the crushing and dismantling roller also includes a rolling spindle 6 and a crushing and dismantling structure. The rolling spindle 6 is located on the outer side above the sintering trolley 1 and the crushing and dismantling structure is provided.

[0023] In this embodiment, the crushing and dismantling structure further includes a material distribution disc 7, a dismantling insert plate 8, and a crushing plug 9. The several material distribution discs 7 evenly divide the rolling spindle 6 into several material distribution compartments from left to right. Each compartment is evenly welded with several dismantling insert plates 8, and the dismantling insert plates 8 divide the compartment into several fan-shaped dismantling compartments. The outer side of each material distribution disc 7 is evenly provided with several crushing plugs 9. The design of the material distribution disc 7 in this structure can crush (shred) the material from the longitudinal direction (front to back) of the material surface, and then crush the material through the crushing plugs 9 on the material distribution disc 7. At the same time, the design of the dismantling insert plate 8 can crush (shred) the material from the transverse direction (left to right) of the material surface. In order to fully crush the material, when assembling the dismantling insert plate 8 and the crushing plug 9, the user can, as shown in the figure, alternately weld the left and right adjacent dismantling insert plates 8 and crushing plugs 9 onto the material distribution disc 7.

[0024] In this embodiment, the water cooling mechanism further includes a water supply main pipe 10, a water spray head 11, a water pump (not shown in the figure), and a water storage tank (not shown in the figure). The water supply main pipe 10 is connected to the water storage tank through the water pump, and the water spray head 11 is connected to the lower side of the water supply main pipe 10 and located above the sintering trolley 11. This structure is designed to accelerate the cooling of the sintering material and reduce dust generated during crushing. The water spray head 11 can also be an atomizing nozzle.

[0025] The working principle of this utility model: The crushing roller of this mechanism can roll as the trolley moves backward after being inserted into the agglomerated material, thereby achieving rolling crushing. It does not require a drive structure, saving energy consumption. The crushing roller can also break up the material that has cooled and agglomerated on the top layer of the sintering trolley 1, so that the trolley can dump the material in sections. At the same time, the crushed material can facilitate the accelerated cooling of the middle layer of material. The water cooling mechanism is designed to accelerate the cooling of the sintered material and reduce the dust generated during crushing.
