Description

Technical Field

[0001] This utility model relates to the field of liquid separation of solid materials, specifically a laboratory mineral precipitation box. Background Technology

[0002] In mineral processing experiments, when there is a large amount of raw material or when conducting scale-up experiments, mineral settling tanks are needed to store and settle the ore solution. Currently used mineral settling tanks have a cubical outer shape. The tank consists of four side plates and a bottom plate. The four side plates are rectangular iron plates arranged vertically, while the bottom plate is a rectangular iron plate arranged at an angle. The side plates and bottom plate form an inner cavity with a cuboid upper section and a right triangular prism lower section. The three lateral edges of the right triangular prism are arranged horizontally, and a discharge port is located at the center of the lowest lateral edge. The discharge port is connected to a discharge pipe, which is equipped with a valve.

[0003] After the slurry settles in the mineral settling tank, the upper layer of clear water is first removed, then the valve on the discharge pipe is opened, and the thick slurry is rinsed with water to allow it to enter the transfer tank before proceeding to the next stage of the experiment. The bottom plate of the tank is inclined, which helps to flush the slurry in the tank to the discharge port and discharge it. However, the bottom of the inner cavity is actually a V-shaped groove extending horizontally, meaning that the lowest point of the tank is a horizontal line. Due to the small size of the discharge port, the flushed slurry does not easily accumulate at the discharge port and tends to accumulate at both ends of the V-shaped groove. A large amount of water is needed to discharge all the slurry, which is time-consuming, labor-intensive, and wasteful of water. Utility Model Content

[0004] This invention provides a mineral sedimentation tank for laboratory use, which solves the problem that the precipitated mineral slurry is not easy to drain from the tank.

[0005] The technical solution adopted by this utility model is as follows: a laboratory mineral precipitation box, comprising a box body formed by four side plates and a bottom plate. The four side plates are arranged vertically, and the bottom plate is arranged at an angle. The side plates and the bottom plate form an inner cavity with a cuboid shape at the top and a right triangular prism shape at the bottom. The three side edges of the right triangular prism are arranged horizontally. The lowest side edge is provided with a ore discharge port, which is connected to a ore discharge pipe. A valve is provided on the ore discharge pipe. A guide plate is provided between the ore discharge port and one or two bottom surfaces of the right triangular prism. The guide plate is triangular and arranged at an angle. The three sides of the guide plate are sealed and fixedly connected to the inner wall of the box.

[0006] To avoid creating impact vortices when the slurry is poured into the tank and to increase the sedimentation rate of the slurry in the tank, at least two partitions are further provided between two opposite side plates or between two adjacent side plates in the tank, with each partition spaced apart; for any two adjacent partitions, the bottom edge of one partition abuts against the bottom plate and the top edge is lower than the top edge of the side plate, while the bottom edge of the other partition has a gap with the bottom plate and the top edge is not lower than the top edge of the side plate.

[0007] To facilitate the installation and removal of the partition, the inner wall of the side panel is provided with a slot into which the partition is inserted; or, the inner wall of the side panel is provided with a bracket into which the partition is installed.

[0008] To better control the flow of molten ore in the gaps between the partitions, the partitions are arranged parallel to each other and at equal intervals, with each partition arranged at an angle, and each partition positioned between the two side plates where the side edges of the right triangular prism are located. The top and bottom edges of each partition are parallel to the two side plates where the bottom surface of the right triangular prism is located.

[0009] To prevent overflow from occurring at the top of all four side panels of the enclosure, an overflow outlet is provided at the top of any one of the four side panels.

[0010] To ensure the strength of the enclosure, the side panels, bottom plate, and baffles are all made of iron plates. The side panels are welded together, as are the side panels and bottom plate, the baffles and bottom plate, and the baffles and side panels. The exposed surfaces of the enclosure are coated with an anti-rust coating.

[0011] To facilitate the movement of the mineral sedimentation tank, the bottom of the tank is equipped with casters, and the side panels of the tank are equipped with handles.

[0012] To facilitate the drainage of the clear water formed after the mineral liquid settles inside the box, furthermore, any one of the four side plates is provided with at least one drain outlet, which is connected to a drain pipe.

[0013] To facilitate the stratified discharge of clear water formed after the mineral liquid settles in the box, the side plate with the ore discharge port is further provided with at least two drainage outlets at vertical intervals.

[0014] To further improve the durability of the drainage pipe, the drainage pipe is made of steel, welded and fixed to the side plate, and equipped with a valve.

[0015] The beneficial effects of this invention are: the guide plate changes the lowest point of the inner cavity of the tank from a horizontal line to a point, and the discharge port is located at this point, that is, the discharge port is located at the lowest point of the inner cavity of the tank. When discharging the thick slurry from the tank by flushing, the slurry can be easily and quickly flushed to the discharge port, reducing the amount of water used for flushing, reducing the time and cost of discharge, and improving the efficiency of discharge.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] This utility model relates to a laboratory mineral precipitation box, comprising a box body formed by four side plates and a bottom plate. The four side plates are arranged vertically, while the bottom plate is arranged at an angle. The side plates and bottom plate form an inner cavity with an upper cuboid shape and a lower right triangular prism shape. Figure 1 As shown, the outer contour of the box is A1B1C1D1A2B2C2D2, the four side panels are A1A2B2B1, B1B2C2C1, C1C2D2D1, and D1D2A2A1, and the bottom plate is A2B2C3D3. Point D3 lies on line segment D1D2, and point D3 lies on line segment C1C2. For example, the length and width of the box are both 1000mm, and the height is 1100mm. The distance between the relatively higher edge C3D3 of the bottom plate and the bottom A2B2C2D2 is 400mm. The three lateral edges of the right triangular prism are all arranged horizontally, that is, lateral edges C3D3 and A2B2 are horizontal, and the other lateral edge... Figure 1 Not shown. A discharge port is located on the lowest side edge for discharging thick slurry. For example, the discharge port has a diameter of 30 mm. See also... Figure 1 If the discharge outlet is marked as point E, then the point is located anywhere on line segment A2B2, including points A2 and B2. The discharge outlet is connected to a discharge pipe, which is equipped with a valve. Thick slurry is discharged through the discharge pipe.

[0020] A guide plate is installed between the discharge port and one or both bases of the right triangular prism. The guide plate is triangular and arranged at an angle, and its three sides are sealed and fixedly connected to the inner wall of the box. When point E corresponding to the discharge port is located at or near points A2 and B2, there is one guide plate; when point E corresponding to the discharge port is located between points A2 and B2, there are two guide plates. See, for example. Figure 1In a right triangular prism, the discharge port is located at the midpoint of the lowest lateral edge A2B2. This means point E, corresponding to the discharge port, is located at the midpoint of line segment A2B2. In this case, the two guide plates are triangles B3EF and A3EG, where point A3 is on line segment A1A2, point B3 is on line segment B1B2, point F is on line segment B2C3, and point G is on A2D3. Generally, when point E, corresponding to the discharge port, is located at the midpoint of lateral edge A2B2, the two guide plates are identical. The guide plates transform the lowest point of the box cavity from a horizontal line to a single point, E, where the discharge port is located. This point is also the only lowest point within the box cavity. When flushing viscous slurry out of the box, the slurry can be easily and quickly flushed to the discharge port.

[0021] To prevent impact vortices from forming when molten ore is poured into the tank, reduce the flow rate of the molten ore, and increase the sedimentation rate within the tank, at least two baffles are installed between opposing side plates or between adjacent side plates inside the tank. These baffles are spaced apart. The baffles divide the inner cavity of the tank into several interconnected small areas, allowing the molten ore poured into the tank to flow between these areas and preventing the formation of impact vortices. Figure 2 As shown, the number of partitions is n, where n is a positive integer greater than 1. Each partition is denoted as MiNi, i = 1, 2, ..., n, for example, n = 5. For any two adjacent partitions, one partition's bottom edge abuts against the base plate, and its top edge is lower than the top edge of the side plate; the other partition has a gap between its bottom edge and the base plate, and its top edge is not lower than the top edge of the side plate. Figure 2 In the illustrated embodiment, i is an odd number, with a gap reserved between the bottom edge of the partition Mini and the bottom plate, and the top edge of the partition Mini is flush with the top edge of the side plate; i is an even number, with the bottom edge of the partition Mini abutting against the bottom plate, and the top edge of the partition Mini being lower than the top edge of the side plate. Both vertical edges of the partition abut against the side plate and are essentially sealed. After the molten mineral is poured into the tank, it flows sequentially along the areas separated by each partition.

[0022] After the slurry has settled, the baffles need to be removed first, then the clear water drained, and finally the thick slurry drained. To facilitate the installation and removal of the baffles, the inner wall of the side panels has slots that fit with the insert plates, and the baffles are inserted into the slots; alternatively, the inner wall of the side panels has brackets, and the baffles are installed in the brackets. For example, a fixing groove for installing the insert plates is welded to the inner wall of the side panels, and the baffles are inserted into the fixing grooves. To better control the flow of the slurry between the baffles, the baffles are arranged parallel to each other and at equal intervals. To prevent the slurry poured into the tank from directly impacting the slurry settled at the bottom, the baffles are arranged at an angle, so that the slurry poured into the tank directly impacts the baffles, reducing the flow rate of the slurry and minimizing the impact of the slurry poured into the tank on the already settled slurry. To facilitate the accumulation of thick slurry at the discharge port, each partition is positioned between the two side plates of the right triangular prism. The top and bottom edges of each partition are parallel to the two side plates of the right triangular prism, meaning that the plane corresponding to each partition is parallel to line segment A1D1.

[0023] The top edges of the four side panels are on the same horizontal plane. To prevent overflow from the top of all four side panels, an overflow port is provided on the top of any one of the four side panels. The height of the overflow port is lower than the height of the top edges of the four side panels. For example, the overflow port is 200mm long, 100mm wide, and 20mm high. To ensure the strength of the tank, the side panels, bottom plate, and guide plates are all made of iron plates. The side panels are welded together, as are the side panels and bottom plate, the guide plates and bottom plate, and the guide plates and side panels, to ensure the airtightness of the tank. To achieve rust prevention, the exposed surfaces of the tank are coated with an anti-rust coating. For example, the tank is constructed by welding angle steel (3mm wide, 2mm thick) and iron plate (2mm thick), and all material surfaces are coated with silver anti-rust paint. To facilitate the movement of the mineral sedimentation tank, the bottom of the tank is equipped with casters, for example, one caster is installed at each of the four corners of the bottom of the tank. To facilitate handling of the enclosure, handles are provided on the side panels; for example, a handle is located on the top of the outer wall of each side panel. The handles can also be used to lift the enclosure.

[0024] After the ore liquid settles within the tank, the upper part of the tank cavity contains clear water, while the lower part contains a thick ore slurry. To facilitate the drainage of the clear water formed after the ore liquid settles, each of the four side plates is equipped with at least one drain outlet, connected to a drain pipe. To facilitate the stratified drainage of the clear water formed after the ore liquid settles, the side plates are provided with at least two drain outlets at vertical intervals. The drain outlets are preferably located on the side plates with ore discharge outlets; a more preferred approach is to have each drain outlet and the ore discharge outlet located on the same vertical line. For example, in... Figure 1In the illustrated embodiment, five drain outlets are provided, designated as points H1, H2, H3, H4, and H5. The drain pipe can be either a rigid pipe or a flexible pipe. By bending the outlet end of the rigid pipe higher than the top edge of the side plate, or fixing the outlet end of the flexible pipe higher than the top edge of the side plate, the drain pipe is effectively blocked. To improve the durability of the drain pipe, it is a rigid pipe, such as a steel pipe, welded to the side plate, and equipped with a valve. For example, the drain pipe is a 10mm diameter steel pipe with a ball valve.
