Description

Technical Field

[0001] This invention relates to the field of coal mine buoyancy test technology, specifically to a zinc chloride recovery device for buoyancy tests. Background Technology

[0002] The float-sink test, also known as density composition analysis or heavy liquid separation test, is one of the most basic and critical analytical tests in the field of coal washing and processing. It usually uses zinc chloride (ZnCl2) aqueous solution to prepare heavy liquids of different densities. By setting heavy liquids of different densities, coal is separated into different density levels, thereby determining the optimal separation density.

[0003] In buoyancy tests, removing and draining floating objects is a crucial step. The specific procedure involves using a ladle to scoop the floating objects from the test bucket into a net-bottom bucket. The net-bottom bucket is then placed at an angle on the side of the test bucket to filter out the zinc chloride heavy liquid. During this process, a large amount of heavy liquid easily leaks from the side wall of the test bucket. Because zinc chloride is expensive, the leaked heavy liquid is difficult to recover, resulting in significant production waste. Furthermore, placing the net-bottom bucket at an angle not only occupies space at the bucket opening but also makes it prone to slipping and falling into the heavy liquid bucket, causing zinc chloride splashing and injury. Zinc chloride is a toxic and corrosive reagent, and its aqueous solution is acidic. If it splashes onto the human body, it can cause irritation and burns to the skin and mucous membranes. If it splashes into the eyes, it can have serious consequences. Therefore, this testing process currently presents significant reagent waste and a major safety hazard. Summary of the Invention

[0004] The purpose of this invention is to provide a zinc chloride recovery device for buoyancy and sinking tests to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a zinc chloride recovery device for a buoyancy and sinking test, comprising several test tanks and walls, the test tanks being placed against the walls, and a recovery component, the recovery component comprising a triangular base plate, one side of the base plate being against the wall, and the other two sides being against and aligned with the inner walls of two adjacent test tanks respectively, the surface of the base plate being bent upward to form a crease for diverting heavy liquid to the inner walls of the two test tanks;

[0006] The base plate is located at a corner between the two test barrels, where a bend is formed by bending upwards to prevent the heavy liquid from flowing to the outer wall of the test barrel. The surface of the base plate is provided with a baffle A for guiding the heavy liquid to flow to the inner wall of the test barrel.

[0007] It also includes a positioning component for limiting the position of the bottom barrel.

[0008] Preferably, the base plate is in the shape of an isosceles triangle or an equilateral triangle.

[0009] Preferably, the positioning component includes a support plate, which is fixedly connected to the side of the base plate near the wall, and the surface of the support plate is provided with a buckle A for surrounding the bottom barrel of the positioning net.

[0010] Preferably, the positioning component includes a support plate, a rotating shaft is fixedly connected to the surface of the support plate, the rotating shaft is rotatably connected to the side of the baffle A near the wall, and a buckle A for surrounding the bottom barrel of the positioning net is provided on the surface of the support plate.

[0011] Preferably, a limiting block for limiting the rotation angle of the support plate is fixedly connected to the side of the support plate near the bottom plate.

[0012] Preferably, the recycling assembly includes a triangular recycling plate, one side of which is attached to the wall, and the other two sides are respectively attached to and aligned with the inner walls of two adjacent test barrels;

[0013] The recovery plate is bent downward at one corner of one of the test barrels to form a support part, so that when the recovery plate is placed on a horizontal plane, its surface gradually decreases in height from the side closer to the support part to the side farther away from the support part, so that the heavy liquid flows only to the test barrel on the side farther away from the support part. The surface of the recovery plate is provided with a baffle B for guiding the heavy liquid to flow to the inner wall of the test barrel.

[0014] Preferably, the recycling plate is in the shape of an isosceles triangle or an equilateral triangle.

[0015] Preferably, one side of the recycling plate is provided with an insert plate, and the surface of the insert plate is provided with a buckle B for surrounding the positioning net bottom barrel.

[0016] Preferably, the recycling plate is fixedly connected to sockets on both sides near the support, and the sockets are pluggable to the plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By setting a bottom plate with a bent surface, this invention can not only raise the bottom of the suspended net bucket through line contact, facilitating the outflow of zinc chloride heavy liquid inside, but also divert the heavy liquid into the test buckets on both sides, improving the heavy liquid recovery and collection efficiency. Furthermore, the bottom plate is set between the two test buckets, reducing the space occupied at the bucket opening, improving the efficiency of scooping floating objects and heavy liquid recovery, thereby effectively reducing the cost of heavy liquid waste.

[0019] 2. This invention sets the base plate in a triangular shape, with its two sides aligned with the inner walls of the two test tanks, allowing the heavy liquid to flow down the inner wall of the test tank instead of dripping. This avoids splashing and waste of zinc chloride heavy liquid, improves the efficiency of heavy liquid recovery, and reduces safety hazards. At the same time, the contact surface between the base plate and the wall can effectively adhere to the wall, better ensuring the stability of the base plate and the mesh bottom tank, and greatly reducing the safety hazard of the mesh bottom tank slipping off and falling into the heavy liquid tank.

[0020] 3. This invention features a recovery plate with a support at one corner that lifts and tilts the plate at a certain angle. Combined with baffle B, this facilitates the directing of zinc chloride heavy liquid into a single test chamber, effectively adapting to the independence of different densities in multi-density test chambers and ensuring the rigor of the test and the authenticity of the data.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] This invention discloses a zinc chloride recovery device for buoyancy and sinking tests, such as... Figure 1-4 As shown, the system includes several test barrels 6 and walls 7. The test barrels 6 are placed against the walls 7, and several test barrels 6 are arranged side by side against the walls 7. Each test barrel 6 is used to hold zinc chloride heavy liquid with the same or different densities for repeated coal float and sink tests. The specific float and sink test operation steps and methods are existing technology and will not be described in detail here. The system also includes a recovery component, which includes a triangular base plate 1. One side of the base plate 1 is attached to the wall 7, and the other two sides are respectively attached to and aligned with the inner walls of two adjacent test barrels 6. Therefore, the spacing between two adjacent test barrels 6 is such that the two sides of the base plate 1 are exactly aligned with the inner walls of the test barrels 6. The surface of the base plate 1 is bent upward to form a fold to divert the heavy liquid to the inner walls of the two test barrels 6. Crease 11, wherein the base plate 1 is in the shape of an isosceles triangle or an equilateral triangle, which makes the base plate 1 have at least two sides of equal length, and the two sides of the base plate 1 are respectively located at the mouth of the two test barrels 6. Therefore, crease 11 should be located on the central axis of the base plate 1, which is in the shape of an isosceles triangle or an equilateral triangle, so that the surface area of ​​the base plate 1 on both sides of crease 11 is equal. By setting crease 11, the height of the base plate 1 is reduced from the center to the surrounding area, that is, the center of the base plate 1 is raised by crease 11. In this way, when the mesh bottom barrel is placed on the surface of the base plate 1, it can contact the crease 11 line and raise the bottom space of the suspended mesh bottom barrel located on both sides of crease 11, so that the zinc chloride heavy liquid in the floating matter in the mesh bottom barrel can leak out and flow downward into the test barrel 6 through the inclined surfaces on both sides of the base plate 1.

[0031] Specifically, since the base plate 1 is supported by two test barrels 6 and one side is stably attached to the surface of the wall 7, the base plate 1 can be stably placed in the gap between the two test barrels 6. This ensures the stability of the base plate 1 and prevents the mesh bottom barrel from falling off. It also effectively avoids occupying the space at the mouth of the test barrel 6, making it easier to scoop out the floating heavy liquid mixture from the test barrel 6 and place the heavy liquid mixture in the mesh bottom barrel on the surface of the base plate 1. The zinc chloride heavy liquid is then filtered out through the bottom of the mesh bottom barrel and flows back into the test barrel 6 through the inclined surfaces of the base plate 1 on both sides of the fold 11. It is worth noting that since the two sides of the base plate 1 are respectively attached to and aligned with the inner walls of the two adjacent test barrels 6, the heavy liquid will flow into the test barrel 6 along the inner wall after leaking from the two sides of the base plate 1, rather than dripping directly, thus avoiding safety hazards such as splashing.

[0032] The base plate 1 has a bend 2 formed by bending upwards at one corner between the two test barrels 6. Since the bend 2 bends upwards, its height after bending is greater than the horizontal height of the crease 11. Therefore, it is used to prevent the heavy liquid from flowing to the outer wall of the test barrel 6. The surface of the base plate 1 is provided with a baffle A311 for guiding the heavy liquid to flow to the inner wall of the test barrel 6. The top height of the baffle A311 is greater than the horizontal height of the crease 11. The baffle A311 is in a ring shape to prevent the heavy liquid from flowing to the side closer to the wall 7, thereby causing waste. It also includes a positioning component for limiting the bottom of the mesh barrel.

[0033] Specifically, by setting baffle A311 and bending part 2, the heavy liquid leaking from the bottom of the bottom plate 1 through the mesh bottom bucket is effectively guided and limited, so as to avoid the heavy liquid flowing out from the outer wall of the test bucket 6 and falling down, causing the waste problem of failed recycling.

[0034] In one embodiment, the positioning component includes a support plate 3, which is fixedly connected to the side of the base plate 1 near the wall 7 and is fitted against the wall 7 to further improve the stability of the base plate 1. The surface of the support plate 3 is provided with a buckle A31 for surrounding the positioning net bottom barrel. The buckle A31 can be circular, square, or polygonal, etc., and the specific shape and size are selected according to the size and shape of the net bottom barrel so as to surround and position the net bottom barrel.

[0035] Specifically, when performing the floating debris removal step, the bottom of the net is inserted into the buckle A31 to fix it in place. Then, the heavy liquid floating debris mixture is scooped into the bottom of the net for filtration.

[0036] In one parallel embodiment, the positioning component includes a support plate 3, on the surface of which a rotating shaft 32 is fixedly connected. The rotating shaft 32 is rotatably connected to the side of the baffle A311 near the wall 7. Therefore, the support plate 3 is rotatable in this embodiment. The surface of the support plate 3 is provided with a buckle A31 for surrounding and positioning the bottom barrel of the net. The buckle A31 can be circular, square, or polygonal, etc. The specific shape and size are selected according to the size and shape of the bottom barrel of the net, so as to surround and position the bottom barrel of the net.

[0037] Specifically, by setting a rotatable support plate 3, its rotation can drive the buckle A31 to rotate synchronously and adjust the mesh bottom barrel it covers, so that the mesh bottom barrel can tilt left and right on the surface of the base plate 1. Since the mesh bottom barrel is in line contact with the crease 11, the tilting of the mesh bottom barrel is around the crease 11. In this way, the mesh bottom barrel can continuously cause its two ends to collide with the surface of the base plate 1 during rotation, generating vibration, which in turn shakes the mixture of solid floating matter and heavy liquid inside, causing it to separate quickly, so that the zinc chloride heavy liquid can be filtered out through impact and vibration.

[0038] The support plate 3 is fixedly connected to a limiting block 33 on the side near the bottom plate 1 to limit the rotation angle of the support plate 3. The limiting block 33 can prevent the support plate 3 from rotating too much, thereby causing the bottom of the net to overturn and improving the stability of the bottom of the net.

[0039] Example 2:

[0040] This invention discloses a zinc chloride recovery device for buoyancy and sinking tests, such as... Figure 5 and Figure 6 As shown, the assembly includes several test barrels 6 and a wall 7. The test barrels 6 are placed against the wall 7, and several test barrels 6 are arranged side by side against the wall 7. Each test barrel 6 is used to hold zinc chloride heavy liquid with the same or different densities for repeated coal float and sink tests. The specific float and sink test operation steps and methods are existing technology and will not be described in detail here. This embodiment provides another implementation method of the recycling component, which aims to provide more feasible cases within the scope of protection of the present invention and as understood by those skilled in the art. The recycling component includes a triangular recycling plate 4. The recycling plate 4 is an isosceles triangle or an equilateral triangle, which makes the recycling plate 4 have at least two sides of equal length. One side of the recycling plate 4 is flush with the wall. The body 7 is attached to the wall 7 on one side to ensure firmness and stability. The other two sides are respectively attached to and aligned with the inner walls of two adjacent test barrels 6. The other two sides are supported by the two test barrels 6. The recovery plate 4 is located at one corner of one of the test barrels 6 and is bent downward to form a support part 41. When the recovery plate 4 is placed on a horizontal plane, its surface gradually decreases in height from the side closer to the support part 41 to the side farther away from the support part 41. Therefore, the entire recovery plate 4 is inclined, so that the heavy liquid flows only to the test barrel 6 on the side away from the support part 41 by gravity. The surface of the recovery plate 4 is provided with a baffle B52 to guide the heavy liquid to flow to the inner wall of the test barrel 6. The baffle B52 is an arc plate with an opening at one end.

[0041] Specifically, by placing the recovery plate 4 between two test barrels 6, with one end of its support 41 away from the test barrel 6 into which the heavy liquid needs to flow, the recovery plate 4 will be tilted toward the side of the test barrel 6 into which the heavy liquid needs to flow. In this way, the zinc chloride heavy liquid filtered by the mesh bottom barrel placed on the surface of the recovery plate 4 will flow on the surface of the tilted recovery plate 4 and enter only one of the test barrels 6, thereby ensuring the independence between adjacent test barrels 6 of heavy liquids with different densities.

[0042] The recycling plate 4 has an insert plate 5 on one side. The surface of the insert plate 5 is provided with a buckle B51 for surrounding and positioning the bottom mesh bucket. The buckle B51 can be circular, square, or polygonal, and its specific shape and size are selected according to the size and shape of the bottom mesh bucket so as to surround and position the bottom mesh bucket. In addition, the buckle B51 is set to be horizontal, so that when it surrounds and fixes the bottom mesh bucket, the bottom mesh bucket is placed horizontally on the surface of the recycling plate 4. Therefore, there is a certain angle gap between the bottom mesh bucket and the inclined surface of the recycling plate 4, which facilitates the leakage of heavy liquid.

[0043] Both sides of the recycling plate 4 near the support part 41 are fixedly connected to sockets 53. The sockets 53 and the plug plate 5 are pluggable and pluggable. Therefore, the plug plate 5 can be plugged and plugged into the two sockets 53 to switch positions. This makes it easy to adjust the position of the plug plate 5 in time after the recycling plate 4 is adjusted, so that it can always fit against the wall 7 and ensure stability.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
