Abstract
Description
Technical Field
[0001] The utility model relates to a structure for preventing the subsidence of an intermediate tank, and belongs to the technical field of intermediate tanks in alumina production. Background Art
[0002] In alumina production, the intermediate tank is used as a buffer and decomposition device for the slurry. During the production process, the applicant found that the existing intermediate tank is prone to sedimentation, resulting in retention of effective ingredients in the slurry. Excessive sedimentation can easily cause blockage and even shutdown for maintenance, which is not conducive to subsequent production.
[0003] For a small intermediate tank with a length, width and height of 2*2*3m, a stirring device needs to be installed to stir at all times to prevent sedimentation, while for a large intermediate tank, the requirements for the stirring device are higher. Therefore, most of the existing ones are equipped with multiple small intermediate tanks, but this method increases the site occupancy, and at the same time, increases the investment in the stirring device, and also increases the energy consumption caused by the constant operation of the stirring device.
[0004] Therefore, there is a need for an anti-settling structure for the intermediate tank, which can prevent settlement in a manner of low energy consumption and smaller site occupation, and is conducive to ensuring the stable operation of the system. Summary of the invention
[0005] In view of this, the purpose of the utility model is to provide a structure for preventing subsidence of an intermediate tank, which can prevent subsidence in a manner of low energy consumption and smaller site occupation, thereby helping to ensure stable operation of the system and overcome the shortcomings of the prior art.
[0006] The purpose of this utility model is achieved through the following technical solutions:
[0007] The utility model discloses an anti-sedimentation structure for an intermediate tank, which comprises an intermediate tank body, wherein a feed port and a discharge port are respectively arranged at the upper and lower ends of the intermediate tank body, and the discharge port is connected to a liquid pump. The utility model is characterized in that a guide plate is arranged inside the intermediate tank body, and the guide plate guides incoming precipitated particles toward the discharge port, and a receiving tray for docking with the incoming materials from the feed port is arranged on the upper side of the intermediate tank body, and the receiving tray uses the incoming material impact force to cause the precipitated particles to fall from one side of the receiving tray into the guide plate.
[0008] The above-mentioned receiving tray structure for making the precipitated particles fall into the guide plate by means of the incoming material impact force comprises a bottom plate and side plates located on the left and right sides of the bottom edge.
[0009] As mentioned above, the side plate on one side of the receiving tray is located above the guide plate, and the side plate on the other side of the receiving tray is located outside the guide plate, and the height of the upper end of the side plate above the guide plate is lower than the height of the side plate outside the guide plate.
[0010] As mentioned above, there are multiple discharge ports.
[0011] As mentioned above, the guide plate is composed of a plurality of arc-shaped plates, and the arc-shaped plates guide the particles from the inner wall of the middle groove or the lower side of the receiving plate to the discharge port.
[0012] As mentioned above, a regular material cleaning port is provided at the bottom of the middle tank body.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model uses a receiving plate to make most of the sedimentation particles and slurry of the incoming materials fall into two areas of the middle tank body respectively, and uses a guide plate to discharge most of the particles to the discharge port. The suction of the liquid pump and the disturbance force of the particles and slurry are used to mix most of the particles with the slurry to achieve non-stirring anti-sedimentation discharge. This method, firstly, utilizes the suction of the existing liquid pump and cooperates with the disturbance force of the particles and slurry to transport most of the sedimentation particles at the first time to prevent the influence of their sedimentation on the operation of the system, which can effectively reduce the number of shutdowns and maintenance, and also extend the regular maintenance time. Secondly, it reduces the investment in the existing stirring device, which can save costs and also reduce the energy consumption caused by the constant operation of the stirring device. Thirdly, this method is also applicable to the use of larger middle tanks. The middle tank that has been put into use is 6*8*6m in length, width and height and can still operate stably, that is, it can replace the use of small middle tanks, which is conducive to saving site space.
[0015] 2. The receiving tray structure, which uses the impact force of the incoming materials to make the precipitated particles fall into the guide plate, includes a bottom plate and side plates located on the left and right sides of the bottom edge, and the bottom plate and the side plates are welded and fixed; during installation, the two ends of the receiving tray are respectively welded and fixed on the inner wall of the upper part of the middle tank body.
[0016] 3. The side plate on one side of the receiving tray is located above the guide plate, and the side plate on the other side of the receiving tray is located outside the guide plate. The upper end of the side plate above the guide plate is lower than the side plate outside the guide plate. With this structure, when in use, the incoming material first falls on the receiving tray, and under the impact of the subsequent incoming material, the particles and slurry in the receiving tray fall from the left and right sides respectively. Since the upper end of the side plate above the guide plate is lower than the side plate outside the guide plate, particles with higher density and greater weight can only fall along the lower side into the guide plate, thereby facilitating the suction and discharge of the liquid pump.
[0017] 4. A regular cleaning port is provided at the bottom of the middle tank body. With such a structure, after long-term use, a small amount of particles in the slurry will also cause sedimentation and accumulation at the bottom of the middle tank body except the guide plate. Therefore, the particles can be discharged regularly through the regular cleaning port and returned to the system for reuse.
[0018] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and will be apparent to those skilled in the art based on the following examination and research, or can be taught from the practice of the present invention to some extent. The objectives and other advantages of the present invention can be achieved and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.
[0025] like Figure 1-Figure 3 As shown, the utility model discloses a method for preventing sedimentation of an intermediate tank. The method uses a receiving plate 4 to make most of the sedimentation particles and slurry of the incoming material fall into two areas of the intermediate tank body 1 respectively, and uses a guide plate 3 to discharge most of the particles to the discharge port 2. The suction of the liquid pump and the disturbance force of the particles and slurry are used to mix most of the particles with the slurry to achieve non-stirring anti-sedimentation discharge. This method, firstly, utilizes the suction of the existing liquid pump and cooperates with the disturbance force of the particles and slurry to transport most of the sedimentation particles at the first time, prevents the influence of their sedimentation on the operation of the system, effectively reduces the number of shutdowns and maintenance, and also extends the regular maintenance time. Secondly, it reduces the investment in the existing stirring device, can save costs, and also reduces the energy consumption caused by the constant operation of the stirring device. Thirdly, this method is also applicable to the use of larger intermediate tanks. The intermediate tank that has been put into use is 6*8*6m in length, width and height and can still operate stably, that is, it can replace the use of small intermediate tanks, which is conducive to saving site space.
[0026] The structure of the middle tank anti-sedimentation comprises a middle tank body 1, wherein a feed port and a discharge port 2 are respectively arranged at the upper and lower ends of the middle tank body 1, and the discharge port 2 is multiple, so that the slurry discharge and particle discharge capacity can be improved through the multiple discharge ports 2, and the discharge port 2 is connected to the liquid pump, and a guide plate 3 is arranged on the inner side of the middle tank body 1, and the guide plate 3 guides the incoming material precipitated particles to the discharge port 2 direction, and the upper side of the middle tank body 1 is connected to the receiving plate 4 of the incoming material from the feed port, and the receiving plate 4 uses the incoming material impact force to make the precipitated particles fall from one side of the receiving plate 4 into the guide plate 3, which is more effective. The receiving tray 4 structure, which uses the impact force of incoming materials to make the precipitated particles fall into the guide plate 3, includes a bottom plate 4-1 and side plates 4-2 located on the left and right sides of the bottom edge, and the bottom plate 4-1 and the side plates 4-2 are welded and fixed; during installation, the two ends of the receiving tray 4 are respectively welded and fixed to the inner wall of the upper part of the middle tank body 1, the side plate 4-2 on one side of the receiving tray 4 is located above the guide plate 3, and the side plate 4-2 on the other side of the receiving tray 4 is located outside the guide plate 3, and the upper end height of the side plate 4-2 above the guide plate 3 is lower than the height of the side plate 4-2 outside the guide plate 3. When such a structure is used, the incoming material first falls on the receiving tray 4. Under the impact of the subsequent incoming material, the particles and slurry in the receiving tray 4 are respectively flushed down from the left and right sides. Since the upper end height of the side plate 4-2 above the guide plate 3 is lower than the height of the side plate 4-2 outside the guide plate 3, the particles with higher density and heavier weight can only fall along the lower side into the guide plate 3, thereby facilitating the suction and discharge of the liquid pump.
[0027] Furthermore, the guide plate 3 is composed of a plurality of arc-shaped plates, which guide the particles from the inner wall of the middle trough body 1 or the lower side of the receiving plate 4 to the discharge port 2. During installation, the arc-shaped plates and the arc-shaped plates and the middle trough body 1 are fixed by welding. Specifically, the inner wall of the middle trough body 1 on the connecting side of the receiving plate 4 is welded to the upper end of the arc-shaped plate, and the side wall of the middle trough body 1 on the discharge port 2 side is welded to one side of the arc-shaped plate. An enclosing structure is formed between the arc-shaped plate and the side wall of the middle trough body 1, thereby facilitating the discharge of particles and slurry toward the discharge port 2.
[0028] Furthermore, a periodic cleaning port is provided at the bottom of the middle tank body 1. With such a structure, after long-term use, a small amount of particulate matter in the slurry will also cause sedimentation and accumulation at the bottom of the middle tank body 1 except the guide plate 3. Therefore, the particulate matter can be discharged regularly through the periodic cleaning port and returned to the system for reuse.
[0029] When in use, the incoming material first falls on the receiving tray 4. Under the impact of the subsequent incoming material, the particles and slurry in the receiving tray 4 are respectively flushed down from the left and right sides, most of which enter the guide plate 3 and are then discharged through the discharge port 2.
[0030] The above is only a preferred embodiment of the utility model, and does not limit the confidentiality of the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still falls within the scope of the technical solution of the utility model.
