Description

Technical Field

[0001] The invention relates to the technical field of concentrate product warehouses, and in particular to a concentrate product warehouse and a construction method thereof. Background Art

[0002] With the development of my country's economy, the development of mines has been increasing. Each mine has concentrate products. Therefore, the concentrate product warehouse is a necessary facility for the beneficiation plant. The particle size of the concentrate product depends on the nature of the ore, ranging from 1mm to 0.001mm. Especially for flotation products, most of the particle size is below 0.074mm. For the convenience of transportation, all products need to be concentrated, filtered and dehydrated, and some need to be dried. However, in order to save costs, most products are only concentrated, filtered and dehydrated. Usually, the moisture content of the filtered products ranges from 10% to 20%. Before transportation, they are generally stored in the product warehouse. During the storage process, the moisture in the product will further seep out and flow out from the bottom. The product at the bottom of the product warehouse often has a higher moisture content, resulting in a wet working environment at the bottom of the warehouse. Usually, the design considers setting up a trench in the concentrate product warehouse to collect the seepage water of the concentrate product, and setting up a submersible pump to recover the seepage water of the concentrate product to the concentration operation. In actual production, if only trenches are set up, the concentrate products will flow into the trenches along with the seepage of the concentrate products. On the one hand, as the production time increases, the trenches are gradually blocked due to the accumulation of concentrates, affecting the production environment; on the other hand, the concentrate products at the bottom of the reservoir contain too much water, and are continuously circulated in the dehydration system by the submerged pump, wasting the capacity of the concentrate product dehydration system. Therefore, it is necessary to invent a concentrate product reservoir that can completely separate the concentrate products from the water in the reservoir, improve the working environment in the concentrate product reservoir, and enhance the capacity of the concentrate product dehydration system. Summary of the invention

[0003] The purpose of the present invention is to provide a concentrate product storehouse and a construction method thereof, which can prevent the concentrate product from leaking out with water and basically achieve zero loss of concentrate products in a ore dressing plant.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: a concentrate product library, the concentrate product library comprising:

[0005] The bottom of the reservoir is the ground;

[0006] A silo wall, installed on the silo bottom, used as a fence for the concentrate product silo;

[0007] A water filter cushion layer is laid on the inner side of the reservoir wall and the reservoir bottom, and is used to store concentrate products. The water in the concentrate products can penetrate through the water filter cushion layer, but the concentrate products themselves cannot pass through the water filter cushion layer.

[0008] The ground has a slope, and a ditch is opened at the lowest point of the slope. The ditch extends from inside the concentrate product warehouse to outside the concentrate product warehouse, and the bottom of the ditch also has a slope, and the elevation of the bottom decreases from inside the concentrate product warehouse to outside the concentrate product warehouse.

[0009] Furthermore, a water pool is provided at one end of the ditch outside the concentrate product storehouse.

[0010] Furthermore, the water filter cushion layer is formed by splicing a plurality of geosynthetics, and the geosynthetics are specifically artificial synthetic cloth or a composite material thereof.

[0011] Furthermore, the slope of the ground is 0.5% to 1%, the slope of the ditch is 0.5% to 1%, the starting elevation of the bottom of the ditch is at least 150 mm lower than the elevation of the lowest point of the ground, and the width of the ditch is greater than or equal to 200 mm and less than or equal to 500 mm, and the bottom elevation of the pool is at least 1000 mm lower than the lowest point elevation of the bottom of the ditch.

[0012] Furthermore, a cover plate with holes is provided on the trench, the upper surface of the cover plate is flush with the elevation of the lowest point of the ground, the opening area of ​​the cover plate accounts for at least 40% of the total area of ​​the cover plate, and the width of the cover plate is 100mm to 120mm larger than the width of the trench.

[0013] A concentrate product storehouse of the present invention can be used for drainage of newly built and existing concentrate product stores of various metal and non-metallic ores, and is particularly suitable for drainage of concentrate product stores of various metal and non-metallic ores with fine concentrate product particle sizes. The construction method thereof comprises the following steps:

[0014] 1) Selection or opening of the storage bottom: According to the scale of the concentrate product to be stored, select a ready-made sloped ground, or artificially open a sloped ground;

[0015] 2) Building a silo wall: According to the scale of the concentrate product to be stored, building a silo wall on the ground in step 1) to preliminarily build the concentrate product silo;

[0016] 3) Opening of trench: Opening a trench with a slope at the lowest point of the ground slope in the concentrate product storehouse in step 1), extending the trench opening to the outside of the concentrate product storehouse, and ensuring that the elevation of the trench bottom surface decreases from the inside of the concentrate product storehouse to the outside of the concentrate product storehouse;

[0017] 5) Installation of the water filter cushion layer: The water filter cushion layer is fixedly connected to the reservoir wall, and ensures that the water filter cushion layer is attached to the inner side of the reservoir wall and the reservoir bottom ground at the same time;

[0018] 6) Seam filling: Seam filling materials are used to fill the corners where the adjacent reservoir walls are connected and the corners where the reservoir walls are connected to the ground to ensure that the water filter cushion layer will not be torn.

[0019] Furthermore, the water filter cushion is formed by splicing together multiple pieces of geosynthetics, and the geosynthetics are specifically artificial synthetic cloth or their composite materials. When making the water filter cushion, adjacent geosynthetics are connected by a hot melt welding process. With the help of this process, all the geosynthetics laid on different surfaces in the concentrate silo are connected as a whole to form a water filter cushion, and the filling material at the corners where adjacent silo walls are connected is polyurethane foam, and the filling material at the corners where the silo wall is connected to the ground is a long bag rolled up with the water filter cushion material filled with fine sand.

[0020] Furthermore, the number of the warehouse walls in step 2) is 1 to 4, all of which are constructed using reinforced concrete.

[0021] Furthermore, the reservoir bottom and the ditch are both constructed by one-step molding using reinforced concrete.

[0022] Furthermore, the fixed connection method described in step 5) is to fix the water filter cushion layer to the reservoir wall with the help of a number of bolts, a number of stainless steel bars with holes, a number of nuts and a number of washers, and ensure that the water filter cushion layer is simultaneously attached to the inner side of the reservoir wall and the reservoir bottom ground, wherein a number of the bolts are fixedly inserted into the top surface of the reservoir wall in a row, and the water filter cushion layer is hung on the reservoir wall through a number of the bolts, and the stainless steel bars are simultaneously strung on a plurality of the bolts with the help of their openings, and the stainless steel bars are also pressed on the water filter cushion layer hung on the bolts, and then the washers and the nuts are sequentially strung on the bolts, and the stainless steel bars are tightly pressed against the water filter cushion layer with the help of the washers and the nuts.

[0023] In summary, the present invention has the following beneficial effects:

[0024] The concentrate product warehouse and its construction method are as follows: the ground of the concentrate product warehouse is made into a certain slope, so that the seepage water of the product can naturally flow to the lowest point of the warehouse bottom, and a ditch is set at the lowest point. A certain slope is also set in the ditch, and a water filter cushion layer is laid on the warehouse wall and the ground. After the concentrate product is stored on the water filter cushion layer, the water in the concentrate product can seep out through the water filter cushion layer and flow into the ditch, while the concentrate product will remain on the water filter cushion layer and will not flow into the ditch with the water. The seepage water can finally flow into the pool along the slope of the ditch, thereby realizing the separation of the concentrate product and water, and preventing the concentrate product from leaking out with the water during the separation.

[0025] This concentrate product warehouse and its construction method are characterized in that the corners where adjacent warehouse walls are connected are filled with polyurethane foam, and the corners where the warehouse wall is connected to the ground are filled with long bags rolled up with water filter cushion materials filled with fine sand. Both the polyurethane foam and the long bags can play a supporting and filling role, which can effectively prevent the water filter cushion layers located at the above two places from being torn.

[0026] The concentrate product silo and its construction method use a plurality of bolts to position the water filter cushion layer so that the water filter cushion layer is firmly hung on the top surface of the silo wall, and then the stainless steel bars, nuts and washers are squeezed and tightened together so that the stainless steel bars tightly press the water filter cushion layer, thereby making it difficult for the water filter cushion layer to fall off from the silo wall.

[0039] Furthermore, a water pool 13 is provided at one end of the trench 4 outside the concentrate product storehouse.

[0040] Furthermore, the water filter cushion layer 6 is formed by splicing a plurality of geosynthetics, and the geosynthetics are preferably geotextiles.

[0041] Furthermore, the slope of the ground 2 is 0.5% to 1%, the slope of the ditch 4 is 0.5% to 1%, the starting elevation of the bottom of the ditch 4 is at least 150 mm lower than the elevation of the lowest point of the ground 2, and the width of the ditch 4 is greater than or equal to 200 mm and less than or equal to 500 mm, and the bottom elevation of the pool 13 is at least 1000 mm lower than the lowest point elevation of the bottom of the ditch 4.

[0042] Furthermore, a cover plate 5 with holes is provided on the trench 4, the upper surface of the cover plate 5 is flush with the elevation of the lowest point of the ground 2, the opening area of ​​the cover plate 5 accounts for at least 40% of the total area of ​​the cover plate 5, and the width of the cover plate 5 is 100mm to 120mm larger than the width of the trench 4.

[0043] A concentrate product storehouse of the present invention can be used for drainage of newly built and existing concentrate product stores of various metal and non-metallic minerals, and is particularly suitable for drainage of concentrate product stores of various metal and non-metallic minerals with fine particle sizes of concentrate products 14. The construction method thereof comprises the following steps:

[0044] 1) Selection or opening of the storage bottom: according to the scale of the concentrate product 14 to be stored, select a ready-made ground 2 with a slope, or artificially open a ground 2 with a slope;

[0045] 2) Establishment of the silo wall 1: According to the scale of the concentrate product 14 to be stored, the silo wall 1 is constructed on the ground 2 of step 1) to initially build a silo for the concentrate product;

[0046] 3) Opening of the trench 4: Opening a trench 4 with a slope at the lowest point of the slope of the ground 2 in the concentrate product storehouse in step 1), extending the trench 4 to the outside of the concentrate product storehouse, and ensuring that the elevation of the bottom surface of the trench 4 decreases from the inside of the concentrate product storehouse to the outside of the concentrate product storehouse;

[0047] 5) Installation of the water filter cushion layer 6: The water filter cushion layer 6 is fixedly connected to the reservoir wall 1, and ensures that the water filter cushion layer 6 is simultaneously attached to the inner side of the reservoir wall 1 and the reservoir bottom ground 2;

[0048] 6) Seam filling: The corners where adjacent reservoir walls 1 are connected and the corners where the reservoir wall 1 is connected to the ground 2 are filled with seam filling materials to ensure that the water filter cushion layer 6 will not be torn.

[0049] Furthermore, the water filter layer 6 is formed by splicing together multiple pieces of geosynthetics, and the geosynthetics are preferably geotextiles. When making the water filter layer 6, adjacent geotextiles are connected by a hot-melt welding process. With the help of this process, all the geotextiles laid on different surfaces in the concentrate silo are connected as a whole to form the water filter layer 6, and the filling material at the corners where adjacent silo walls 1 are connected is polyurethane foam 7, and the filling material at the corners where the silo wall 1 is connected to the ground 2 is a long bag 8 rolled up with the water filter layer 6 material filled with fine sand.

[0050] Furthermore, in step 2), the number of the storage walls 1 is 1 to 4, all of which are constructed using reinforced concrete and have good load-bearing performance.

[0051] Furthermore, the concentrate product 14 is heavy, so the reservoir bottom and the trench 4 are both constructed by one-step molding using reinforced concrete, which can effectively improve the load-bearing performance of the reservoir bottom and the trench 4.

[0052] Furthermore, the fixed connection method in step 5) is to fix the water filter cushion layer 6 to the reservoir wall 1 with the help of a number of bolts 10, a number of stainless steel bars 9 with holes, a number of nuts 12 and a number of washers 11, and ensure that the water filter cushion layer 6 is simultaneously attached to the inner side of the reservoir wall 1 and the reservoir bottom ground 2, wherein a number of bolts 10 are fixedly inserted into the top surface 3 of the reservoir wall 1 in a row, and the water filter cushion layer 6 is hung on the reservoir wall 1 through a number of bolts 10, and the stainless steel bars 9 are strung on multiple bolts 10 at the same time by means of their openings, and the stainless steel bars 9 are also pressed on the water filter cushion layer 6 hanging on the bolts 10, and then the washers 11 and nuts 12 are strung on the bolts 10 in sequence, and the stainless steel bars 9 are tightly pressed against the water filter cushion layer 6 by means of the washers 11 and nuts 12.

[0053] See also Figure 1-5 The present invention requires that the concentrate product warehouse be constructed into a concentrate product warehouse that meets the design scale requirements, including a concentrate product warehouse that meets the volume, load-bearing, loading and drainage requirements. The warehouse wall 1 is made into a high-strength reinforced concrete wall structure similar to a retaining wall and is perpendicular to the ground 2; the warehouse wall 1 and the ground 2 can withstand all concentrate products and their own loads, so their foundation must be firm; bolts 10 are pre-embedded in the warehouse wall 1, and the bolts 10 are perpendicular to the top surface 3 of the warehouse wall 1 and exposed 60mm on its top surface 3. The position where the bolts 10 are inserted is at least 200mm away from the side wall of the warehouse wall 1, and the spacing between adjacent bolts 10 is 500mm. The elevation of the top surface 3 of the warehouse wall 1 is H2, and the diameter of the bolts 10 can be 18-24mm to facilitate the installation of geotextiles; the ground 2 is made of 0.5- A slope of 1% allows the seepage water of the product to flow naturally to the lowest point of the bottom of the reservoir. The starting elevation of the ground 2 is H0, and the lowest elevation of the ground 2 is H1. A trench 4 is set at the elevation of the lowest point H1 of the ground 2. A slope of 0.5-1% is also set in the trench 4. The starting elevation of the bottom of the trench 4 is H3, which is at least 150mm lower than H1. A trench cover 5 with holes is set on the trench, and the upper surface of the trench cover 5 is flush with the lowest elevation H1 of the ground 2; a pool is opened at one end of the trench outside the concentrate product warehouse, the lowest point elevation of the bottom of the trench 4 is H4, the bottom elevation of the pool 13 is H5, and H5 is at least 1 meter lower than H4.

[0054] The height and strength of the silo wall 1 can be determined according to the terrain and the scale and size of the concentrate product silo; the concentrate product silo can be made into a silo with silo walls on all sides, or a silo with silo walls on three or two sides and one or two sides open, or even a silo with silo wall on one side and three sides open, which mainly depends on the loading method, storage capacity requirements and site conditions. The concentrate product silo with silo walls on all sides is suitable for grab loading; the other concentrate product silos with silo walls on three, two or one sides can be loaded by grab loading, bulldozer or forklift.

[0055] The position of the ditch 4 can be set at different parts of the concentrate product warehouse according to the scale and size of the concentrate product warehouse, such as at one end or the middle part of the concentrate product warehouse, and the general principle is to facilitate water collection and self-flow; the width of the ditch 4 is generally greater than or equal to 200mm and less than or equal to 500mm.

[0056] The method of ground 2 is closely related to the position of ditch 4. Ground 2 slopes toward ditch 4. When ditch 4 is located at one end of the concentrate product warehouse, ground 2 slopes toward ditch 4 from the other end of the concentrate product warehouse; when ditch 4 is located in the middle part of the concentrate product warehouse, ground 2 slopes toward ditch 4 from both ends at the same time.

[0057] The trench cover 5 can be made into a prefabricated part with holes using reinforced concrete or steel materials. Under the premise of meeting the load requirements, the opening area of ​​the trench cover 5 must be at least 40%, and the width of the trench cover 5 must be 100 to 120 mm larger than the width of the trench 4. The length and weight of the trench cover 5 can be convenient for construction operations.

[0058] The position of the pool 13 is closely related to the slope of the trench 4. According to the terrain and site size, the principle is to collect and flow water 15 by gravity. The volume of the pool 13 is determined according to the scale of the concentrate product warehouse. If the concentrate product warehouse is large, has many products, and has a lot of seepage water 15, the pool 13 can be larger, otherwise it can be smaller; in addition, if the water 15 in the pool 13 can flow to the enterprise return water pool by gravity, it can be smaller. If pumping is required, the appropriate volume needs to be designed according to the pump lift.

[0059] Geotextile is used to lay on the product warehouse wall 1, the ground 2 and the trench cover 5, so that the concentrate product 14 is stored on the geotextile. The water 15 in the concentrate product 14 can seep out through the geotextile and flow into the trench 4, while the concentrate product 14 remains on the geotextile and will not flow into the trench 4 with the water 15, thereby ensuring that the concentrate product 14 is separated from the water 15, thereby achieving the purpose of preventing the concentrate product 14 from leaking.

[0060] Each roll of geotextile is 4 to 6 meters wide and 108 meters long; each stainless steel bar 9 is 2 to 3 meters long and 200 mm wide, with a hole spacing of 500 mm in the length direction, the same as the spacing of the embedded bolts 10, the first hole is 200 mm away from the edge at a minimum, and a hole is opened in the middle in the width direction. The thickness of the stainless steel bar 9 can be 3 to 6 mm.

[0061] The construction technology of geotextile can be carried out by adopting mature construction technology such as hanging, laying and hot melting.

[0062] The geotextile is hung on the pre-buried bolts 10 on the top surface 3 of the warehouse wall 1, and the geotextile is spread along the top surface 3 of the warehouse wall 1. A lap width of 150 mm needs to be left between adjacent geotextiles. When the geotextile is spread on the pre-buried bolts 10, holes of appropriate sizes need to be opened and inserted into the bolts 10. Then the stainless steel bar 9 with the holes opened is also inserted into the bolts 10 and pressed on the geotextile. Then the washer 11 is inserted into the bolt 10 and pressed on the stainless steel bar 9. Finally, the nut 12 is inserted into the bolt 10 and pressed on the washer 11 and the nut 12 is tightened to fix the geotextile on the top surface 3 of the warehouse wall 1.

[0063] Adjacent geotextiles are constructed by hot-melt welding to ensure that the welds are tight and reliable and pass the inspection. The geotextiles at the intersection of the two adjacent silo walls 1 and the intersection of the silo wall 1 and the ground 2 are connected by hot-melt welding; the geotextile on the ground 2 is constructed by direct laying and hot-melt welding; the corners where the silo walls 1 are connected are filled with polyurethane foam 7 to prevent the geotextile from tearing; the corners where the silo walls 1 are connected with the ground 2 are filled with long bags 8 rolled up with fine sand to prevent the geotextile from tearing.

[0064] When the scale of the concentrate product warehouse is very large, the warehouse wall 1 may be coaxial with the pillars of the factory building, and the pillars are large and protrude from the warehouse wall 1. In this case, the pillars protruding from the warehouse need to be wrapped with geotextiles. At this time, it is necessary to pre-embed the bolts 10 into the side surface of the pillar at an elevation of H2. At least two bolts 10 are buried on the side of each pillar. The corresponding stainless steel bar 9 opening distance is also adjusted accordingly. The geotextile is inserted into the pre-embedded bolts 10, and the geotextile is fixed to the side surface of the pillar with stainless steel bars 9, washers 11 and nuts 12 in turn. In this way, the pillars protruding from the warehouse are wrapped with geotextiles. The corners where the warehouse wall 1 and the pillars are connected are filled with polyurethane foam 7 to prevent the geotextile from tearing; the corners where the pillars are connected to the ground 2 are filled with long bags 8 rolled up with fine sand to prevent the geotextile from tearing.

[0065] Geotextiles can be made of different materials, such as polyester staple needle-punched geotextiles, drainage mats and other geosynthetics. The appropriate geotextile is selected according to the particle size of the concentrate product 14. The good air permeability and water permeability of the geosynthetics are utilized to allow water 15 to pass through, while fine particles and powder, i.e., the concentrate product 14, are effectively retained to prevent the loss of the concentrate product 14, thereby achieving the purpose of separating the concentrate product 14 from water 15.

[0066] A specific implementation method 2 of a concentrate product warehouse and a construction method thereof of the present invention (when the concentrate product warehouse has been built) is as follows:

[0067] If the built concentrate product warehouse has been constructed with trench 4, trench cover 5, and pool 13, it is sufficient to clean the surface of the built concentrate product warehouse, and other construction processes are the same as those in Example 1. Geotextile is laid on the product warehouse wall 1 and the ground 2, so that the concentrate product 14 is stored on the geotextile, and the water 15 in the concentrate product 14 can seep out through the geotextile and flow into the trench, while the concentrate product 14 remains on the geotextile and will not flow into the trench with the water 15, ensuring that the concentrate product 14 is separated from the water 15, thereby achieving the purpose of preventing the concentrate product 14 from leaking.

[0068] A specific implementation method 3 of a concentrate product warehouse and a construction method thereof of the present invention (when the concentrate product warehouse has been built) is as follows:

[0069] If the existing concentrate product warehouse does not have a trench 4, a trench cover 5, a pool 13, and the concentrate product warehouse has four walls, it is necessary to clean the surface of the existing concentrate product warehouse, and at the same time, appropriately transform the ground 2 so that the ground has a minimum slope of 0.5% and slopes toward the non-unloading end. A trench 4 is set at the lowest point of the ground, and a minimum slope of 0.5% is also set in the trench. A trench cover 5 with holes is set on the trench 4, and a pool 13 is set at the lowest point of the trench 4 in the product warehouse; other construction processes are the same as those of the new one.

[0070] Geotextiles are used to lay the walls 1 and the ground 2 around the product warehouse, so that the concentrate product 14 is stored on the geotextiles. The water 15 in the concentrate product 14 can seep out through the geotextiles and flow into the ditch 4, while the concentrate product 14 remains on the geotextile and will not flow into the ditch 4 with the water 15, ensuring that the concentrate product 14 is separated from the water 15, thereby achieving the purpose of preventing the concentrate product 14 from leaking. For the transformation of such a concentrate product warehouse that has been built and does not have a ditch 4, a ditch cover 5, and a pool 13 in the concentrate product warehouse, part of the storage capacity will be reduced, but it is still very beneficial to the operating environment and the recovery of seepage water after the transformation, and it is worth doing the transformation.

[0071] A specific implementation method 4 of a concentrate product warehouse and a construction method thereof of the present invention (when the concentrate product warehouse has been built) is as follows:

[0072] If the existing concentrate product warehouse does not have a trench 4, a trench cover 5, a pool 13, and the concentrate product warehouse has one or more sides open, that is, the concentrate product warehouse is not closed, then it is necessary to clean the surface of the existing concentrate product warehouse, and at the same time, appropriately transform the ground 2 so that the ground has a minimum slope of 0.5% and slopes toward the open end, that is, the side where the warehouse wall 1 is not set, set a trench 4 at the lowest point of the ground 2, and also set a minimum slope of 0.5% in the trench 4, set a trench cover 5 with holes on the trench 4, and set a pool 13 somewhere on the extension line of the trench 4 outside the product warehouse; other construction processes are the same as those of the new construction. Geotextiles are used to lay on the product warehouse wall 1 and the ground 2, so that the concentrate product 14 is stored on the geotextiles, and the water 15 in the concentrate product 14 can seep out through the geotextiles and flow into the ditch, while the concentrate product 14 remains on the geotextile and will not flow into the ditch with the water 15, ensuring that the concentrate product 14 is separated from the water 15, thereby achieving the purpose of preventing the concentrate product 14 from leaking. For the transformation of such a concentrate product warehouse that has been built and does not have a ditch 4, a ditch cover 5, and a pool 13 in the concentrate product warehouse, part of the storage capacity will be reduced, but it is still very beneficial to the operating environment and the recovery of seepage water after the transformation, and it is worth doing the transformation.

[0073] It should be noted that: when loading and unloading concentrate during the production process, try to avoid the loading and unloading equipment being close to the ground 2 and the silo wall 1, that is, retaining the concentrate product 14 at the edge and bottom, to avoid the loading and unloading equipment from scratching the geotextile and ensure the integrity of the concentrate product silo.

[0074] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, if several equivalent substitutions or obvious modifications are made without departing from the concept of the present invention, and the performance or use is the same, it should be regarded as belonging to the protection scope of the present invention determined by the submitted claims.
