Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sintering and mixing, in particular to a sintering and mixing continuous production line with an emergency system. Background Art
[0002] The sintering process includes batching, mixing, laying, ignition, sintering, crushing, cooling, screening, conveying, circulation and other production links, among which the mixing operation is the link that undertakes batching, sintering transfer and belt conveying. Due to the characteristics of sintering production, it is necessary to maintain a long-term stable continuous operation state. Therefore, if there are equipment operation problems in each link and the conditions for use are not met, the entire production line needs to be shut down, causing major production losses. Especially large equipment: such as mixers, including high-voltage motors, reducers, hydraulic couplings, guide plates, tugboat assembly, gear assembly, roller assembly, inlet and outlet funnel assembly, lubrication system, water and steam configuration, and cylinder and liner, etc., involving production mixing, water wetting and other process operations, the equipment has a large load and a long operating cycle. It is easy to have equipment transmission, accessories and main body failures, resulting in equipment accidents such as production line shutdowns, and the equipment failure processing time is long, and the impact is very serious.
[0003] The normal sintering process is that the batching conveyor belt in the batching room directly enters the primary mixer for wetting and mixing. The wetted and mixed materials are transported to the secondary mixer through two belts, and then mixed and granulated in the secondary mixer before entering the next belt conveyor until the mixing bin of the sintering machine. This part of the process is the batching and mixing process in the sintering production process, and also belongs to the feeding system process. Based on this process, if any mixer has equipment failure or mixer process problems, such as water pipe blockage, etc., it needs to be shut down for processing if necessary, thereby interrupting the normal production organization, causing the entire production line to shut down and repair, affecting subsequent production. Utility Model Content
[0004] The purpose of the utility model is to solve the above problems and to design a sintering mixing continuous production line with an emergency system, which solves the problem of production interruption caused by equipment failure of any mixer in the sintering mixing system.

Detailed Embodiment
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0019] As Figure 1 shown, a preferred embodiment of the present utility model provides a sintering mixing continuous production line with an emergency system. The mixing production line of the sintering materials mainly includes a primary mixing feeding belt line 1, a primary mixer 2, a primary mixing discharging belt line 3, a secondary mixing feeding belt line 4, a secondary mixer 5, a secondary mixing discharging belt line 6, a primary mixing emergency belt line 7, a secondary mixing emergency belt line 8 and two distributors 9.
[0020] The feeding end of the primary mixing feeding belt line 1 is docked with the batching chamber, and the discharging end is docked with the primary mixer 2. In the batching chamber, the materials to be mixed are prepared in proportion and conveyed to the primary mixer 2 by the primary mixing feeding belt line 1. A certain proportion of water is added to the primary mixer 2 to wet and mix the materials. A discharging chute 11 is installed at the outlet of the primary mixer 2. The discharging chute 11 is inclined, and the other end thereof is docked with the primary mixing discharging belt line 3. The mixed materials will slide down through the discharging chute 11 onto the primary mixing discharging belt line 3.
[0021] The other end of the primary mixing discharging belt line 3 is docked with the secondary mixing feeding belt line 4 through a feeding chute 10. The materials are conveyed from the primary mixing discharging belt line 3 onto the feeding chute 10. The structure of the feeding chute 10 is the same as that of the discharging chute 11. The materials will slide down through the feeding chute 10 onto the secondary mixing feeding belt line 4, and the materials enter from the side of the secondary mixing feeding belt line 4.
[0022] A plurality of wheels 12 are installed at the bottom of the secondary mixing feeding belt line 4. Therefore, the secondary mixing feeding belt line 4 can be moved. The discharging end of the secondary mixing feeding belt extends into the secondary mixer 5. The secondary mixer 5 is used for granulation. The materials are mixed and stirred in the secondary mixer 5 to finally form particles. The secondary mixing feeding belt line 4 conveys the materials to the inner side of the secondary mixer 5 to prevent the materials from accumulating at the inlet of the secondary mixer 5.
[0023] The secondary mixing feeding belt line 4 is manually pushed into or out of the secondary mixer 5. If the secondary mixer 5 breaks down and needs to be repaired, the secondary mixing feeding belt line 4 can be pushed out.
[0024] The outlet of the secondary mixer 5 is docked with the secondary mixing discharging belt line 6 through a discharging chute 11. The materials are finally conveyed by the secondary mixing discharging belt line 6 to the next conveying process until the mixing material bin of the sintering machine.
[0025] The primary mixing emergency belt line 7 and the secondary mixing emergency belt are used for emergency when the primary mixer 2 and the secondary mixer break down respectively.
[0026] In this embodiment, the belt line is driven by a motor to move the belt, thereby conveying the materials. Baffles are provided on both sides of each belt line to prevent the materials from flowing out. The feeding chute 10 and the discharging chute 11 are also driven by a motor to move the belt to transfer the materials to the designated position. A chute can also be used, and the chute is inclined downward, and the function is the same.
[0027] There is a discharge port on the side of the primary mixing feed belt line 1. An upfeed chute 10 is installed at the discharge port. The other end of the upfeed chute 10 is docked with the primary mixing emergency belt line 7, and it can be selectively docked with the feed end of the primary mixing emergency belt line 7 or the side of the primary mixing emergency belt line 7. The discharge end of the primary mixing emergency belt line 7 is docked with the primary mixing discharge belt line 3 through a downfeed chute 11. A diverter 9 is installed at the position where the discharge port is located to guide the material into the upfeed chute 10.
[0028] There is a feed port on the side of the primary mixing discharge belt line 3, and the downfeed chute 11 is installed at this feed port. When the primary mixer 2 breaks down, the material on the primary mixing feed belt line 1 will be guided by the diverter 9 onto the primary mixing emergency belt, and then conveyed by the primary mixing emergency belt to the primary mixing discharge belt line 3, and then conveyed to the secondary mixer 5 through the secondary mixing feed belt line 4. At this time, the two processes of adding water for wetting and mixing and granulating the material are both completed in the secondary mixer 5.
[0029] There is also a discharge port on the side of the primary mixing discharge belt line 3. A downfeed chute 11 is installed at this discharge port. The other end of the downfeed chute 11 is docked with the secondary mixing emergency belt line 8 to facilitate the material to flow onto the secondary mixing emergency belt line 8. A diverter 9 is installed at the position where the discharge port is located to guide the material into the downfeed chute 11.
[0030] The discharge end of the secondary mixing emergency belt line 8 is docked with the side of the secondary mixing discharge belt line 6 through a downfeed chute 11, and the material enters the secondary mixing discharge belt line 6 from the side through the downfeed chute 11.
[0031] When the secondary mixer 5 breaks down, the two processes of adding water for wetting and mixing and granulating the material are both completed in the primary mixer 2. Then, the secondary mixing emergency belt line 8 is started, and the material will be guided by the diverter 9 onto the secondary mixing emergency belt and conveyed to the secondary mixing discharge belt line 6 through the secondary mixing emergency belt line 8.
[0032] As Figure 2 shown, the above-mentioned diverter 9 is composed of a support 91, a fixing frame 92, a guiding plate 93, and a driving mechanism 94. Among them, the support 91 is fixedly installed on the belt line and horizontally frames above the belt line. The fixing frame 92 is welded by multiple rods and is used to fix the guiding plate 93. The two sides of the fixing frame 92 are respectively hinged to the two sides of the support 91. In this embodiment, the driving mechanism 94 uses an oil cylinder. The tail end of the oil cylinder is hinged to the top of the support 91, and the output end is connected with a connecting rod 95. The other end of the connecting rod 95 is hinged to the fixing frame 92, and the fixing frame 92 is pulled to turn up and down by the oil cylinder.
[0033] The guide plate 93 is an inclined surface, which forms a certain angle with the conveying direction of the belt line. The guide plate 93 is installed and fixed on the front side of the fixed frame 92. When the primary mixer 2 or the secondary mixer 5 fails, the oil cylinder drives the fixed frame 92 to flip downward, and the guide plate 93 flips downward and closely adheres to the belt line. At this time, the material will enter the primary mixing emergency belt line 7 or the secondary mixing emergency belt line 8 under the blocking and guidance of the guide plate 93.
[0034] In other technical solutions, the distributor 9 may also be a plough-type distributor 9 or the like.
[0035] The distributor 9 belongs to the emergency system. When the primary mixer 2 fails, the distributor 9 can be lowered by electronic control to guide the material into the flow channel and finally into the primary mixing emergency belt. The material is directly transported to the primary mixing discharge belt through the primary mixing emergency belt to complete the emergency material transportation and maintain the continuous operation of production.
[0036] The same is true for the secondary mixer 5. When the secondary mixer 5 or the secondary mixing feed belt fails, it needs to be shut down for maintenance. The emergency organization process is as follows: put down the divider 9 (normally the divider 9 is in a raised state and does not affect material transportation), guide the material into the secondary mixing emergency belt line 8, and transport the material to the secondary mixing discharge belt through the secondary mixing emergency belt to complete the emergency operation.
[0037] After the fault points in each link of the primary mixer 2 or the secondary mixer 5 and the secondary mixing feeding belt are repaired, the corresponding maintenance equipment can be opened in sequence, the distributor 9 can be lifted, the normal operation can be restored, and the emergency belt line can be gradually stopped.
[0038] If any one of the two mixers fails, the other mixer will need to take on the two processes of adding water to wet and mix the materials, and granulating them at the same time. Normal production can be resumed when the failure is eliminated.
[0039] Because all the equipment in normal operation is in interlocking state, the shutdown of the upper link will cause the interlocking shutdown of the equipment in the lower area. Therefore, when the mixer fails and needs to be shut down to use the emergency belt, the control center will unblock the faulty equipment, and after the emergency belt system is turned on and integrated into the interlocking state, the single-action shutdown of the fault point equipment can be selected. The same principle applies to opening. After the fault is repaired, the control center will unblock the emergency belt system, turn on the repaired equipment and integrate it into the interlocking state, and then lift the materials from the distributor 9 to enter the normal production process, and the emergency belt will be shut down normally for standby.
[0040] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
