Description

Technical Field

[0001] This utility model belongs to the technical field of mining storage equipment, specifically disclosing a tool for clearing blockages in fine material silos in crushing workshops. Background Technology

[0002] For mineral processing enterprises, crushing systems are essential. After crushing, ore particles are often stored in fine silos. Due to geographical limitations in the early stages of plant construction, some enterprises have limited space above the fine silos, severely restricting the operating space. Because the ore particles contain powdery materials, they are easily affected by the environment and tend to accumulate or stick together. After the material properties change, the fine silos become severely caking, which not only leads to a sharp decrease in effective volume but also easily causes material sloshing and blockage, affecting the normal production of downstream processes and restricting the system flow. In severe cases, it can even cause system shutdown. Due to the limited operating space, various methods have been tried to unclog the silos, but the results have been unsatisfactory. Summary of the Invention

[0003] To address the problems in the background art, this utility model discloses a dredging tool for clogging the fine material bins in a crushing workshop, comprising a feed cone, an extension pipe, and a seepage pipe. Water seeps into the material through the extension pipe and the feed cone, causing the material to disperse and effectively solving the clogging phenomenon caused by the caking of ore materials.

[0004] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0005] A tooling for unblocking clogged fine material silos in a ore crushing workshop includes a conical feed cone with its tip pointing downwards. The flat end of the feed cone is connected to the lower end of a vertically arranged seepage pipe. The seepage pipe has several seepage holes penetrating its wall. The upper end of the seepage pipe is detachably connected to an end cap via several sequentially connected extension pipes. The end cap has a water inlet. Both the seepage pipe and the extension pipes are pipe structures, and the cavities of the seepage pipe and the extension pipes are connected to an inlet pipe through the water inlet.

[0006] Furthermore, in the unblocking tool for the fine material silo in the crushing workshop, the seepage pipe and the extension pipe, as well as adjacent extension pipes, are connected by a connector, which is a double-ended internal thread structure.

[0007] Furthermore, the unblocking tool for the fine material silo in the crushing workshop has a partition plate in the middle of the connector, a through hole in the middle of the partition plate, and a baffle plate below the through hole. One side of the baffle plate is hinged to the partition plate, and a compression spring is also provided between the baffle plate and the partition plate on the side of the baffle plate near the hinge axis. The other side of the baffle plate is magnetically connected to the partition plate by a magnet. Under the combined action of the compression spring, the magnet and gravity, the baffle plate can rotate relative to the partition plate to open and close the through hole.

[0008] Furthermore, the unblocking tool for the fine material silo in the crushing workshop has a sliding rod fixedly connected to the bottom of the baffle, extending along the rotation path of the baffle, and a sliding sleeve fixedly connected to the bottom of the partition, extending along the rotation path of the baffle. The sliding rod is slidably connected to the sliding sleeve, and a compression spring is provided inside the sliding sleeve. One end of the compression spring is connected to the sliding rod, and the other end of the compression spring is connected to the partition.

[0009] Furthermore, the unblocking tool for the fine material silo in the crushing workshop has a flat end radius of the feed cone that is larger than the diameter of the seepage pipe.

[0010] Furthermore, the unblocking tool for the fine material silo in the crushing workshop is provided with handles on the upper part of the extension pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model relates to a tooling for unblocking clogged fine material silos in ore crushing workshops. It includes an inlet cone, a drainage pipe, and extension pipes. The drainage pipe and extension pipes are detachably connected. Several extension pipes are sequentially connected to the upper end of the drainage pipe as needed. The length of the tooling can be freely adjusted by connecting multiple extension pipe sections to solve clogged fine material silos of various heights. Each extension pipe section is relatively short, making it suitable for locations with limited space. During operation, the inlet cone is inserted into the material in the fine material silo, with the uppermost extension pipe extending out of the silo. Water is introduced into the drainage pipe and extension pipes through the water inlet pipe, allowing the water to slowly seep into the material, eventually causing the material to disperse and thus unblock the silo. After unblocking, the tooling can be removed by reversing the installation process, pulling out each extension pipe in turn. This utility model is very convenient to use and can effectively solve the clogged phenomenon caused by ore material caking, increasing the volume of the fine material silo.

Detailed Implementation

[0016] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0017] Combined with appendix Figure 1 and attached Figure 2 This invention details a tool for unclogging a fine material silo in a crushing workshop. It includes a conical inlet cone 1 with its tip pointing downwards. The flat end of the inlet cone 1 is connected to the lower end of a vertically positioned drainage pipe 2. The radius of the flat end of the inlet cone 1 is larger than the diameter of the drainage pipe 2, ensuring that water can flow smoothly into the material while effectively preventing material particles from entering the drainage holes 3 and causing blockage. The drainage pipe 2 has several drainage holes 3 penetrating its wall. The upper end of the drainage pipe 2 is detachably connected to an end cap 7 via several sequentially connected extension pipes 5. The end cap 7 has a water inlet 8. Both the drainage pipe 2 and the extension pipes 5 are pipe structures. The cavities of the drainage pipe 2 and the extension pipes 5 are connected to a water inlet pipe via the water inlet 8. During operation, holes are opened at suitable locations above the fine material silo where space is limited. As needed, holes are sequentially opened at the upper end of the drainage pipe 2... Connecting several extension pipes 5 allows for flexible adjustment of the unblocking fixture's length, resolving blockages in fine material silos of various heights. Each extension pipe 5 is relatively short, making it suitable for locations with limited space. The feed cone 1 is inserted into the material in the fine material silo, with the uppermost extension pipe 5 extending out of the silo. Water is introduced into the seepage pipe 2 and extension pipes 5 via the water inlet pipe. The water flow is adjusted according to the degree of material caking, keeping it as small as possible to allow the water to slowly seep into the material, eventually causing it to disperse and clear the blockage. This effectively solves the blockage caused by ore material caking, increases the fine material silo volume, ensures normal and stable operation of production equipment, and saves equipment maintenance time. By reducing downstream ball mill downtime by one hour per month, the company can save 150,000 yuan annually. Furthermore, the device has no hazardous factors during operation, ensuring personnel safety.

[0018] As an optional design, the preferred unblocking fixture for the fine material silo blockage in the crushing workshop is that the seepage pipe 2 and the extension pipe 5, as well as adjacent extension pipes 5, are connected by a connector 4. The connector 4 has a double-ended internal thread structure. By connecting the extension pipes 5 step by step through the connector 4, the length of the unblocking fixture is increased, so that the feed cone 1 can be inserted into the material blocking the fine material silo. It can also be operated in a space with limited height, reducing the danger of unblocking the fine material silo in the workshop, while unblocking the material in the fine material silo and ensuring normal production operation.

[0019] As an optional design, the preferred unblocking fixture for the fine material silo in the crushing workshop includes a connector 4 comprising a tubular wall 4.1, a partition 4.2 in the middle of the wall 4.1, a through hole penetrating the upper and lower surfaces of the partition 4.2 in the middle of the partition 4.2, a baffle 4.4 below the through hole, one side of the baffle 4.4 being hinged to the partition 4.2, and a compression spring 4.7 between the baffle 4.4 and the partition 4.2 on the side of the baffle 4.4 adjacent to the hinge shaft 4.3. On the other side, there is a protruding plug. A matching groove is provided at the bottom of the partition 4.2 corresponding to the plug. A magnet B4.9 is embedded in the plug, and a magnetic strip A4.5 is provided at the bottom of the groove. The partition 4.2 and the baffle 4.4 are magnetically connected by the magnet B4.9 and the magnetic strip A4.5. Under the combined action of the compression spring 4.7, the magnet, and gravity, the baffle 4.4 can rotate relative to the partition 4.2 to open and close the through hole. During operation, when there is no water injected into the extension tube 5 at the upper end of the connector 4, the partition 4... 4.2 is magnetically connected to baffle 4.4 to seal the through hole. When a certain amount of water is injected into the extension tube 5 at the upper end of connector 4, the weight of the water is greater than the magnetic attraction between magnet B4.9 and magnetic strip A4.5. The partition 4.2 rotates clockwise downwards relative to baffle 4.4, compressing spring 4.7 and accumulating potential energy. The through hole opens, and water in the extension tube 5 at the upper end of connector 4 flows into the corresponding extension tube 5 below it or into seepage tube 2. The compressed spring 4.7 releases the accumulated potential energy, and the partition 4.2 rotates counterclockwise upwards relative to baffle 4.4. Rotate, and the magnets B4.9 and A4.5 magnetically attract each other, sealing the through hole again. Water in the seepage pipe 2 flows out through the seepage hole 3 to the end face of the feed cone 1, and finally slowly seeps into the material along the side of the feed cone 1, avoiding direct connection between the extension pipe 5 and the cavity of the seepage pipe 2. The water pressure in the seepage pipe 2 is relatively high, causing the water in the extension pipe 5 and the cavity of the seepage pipe 2 to flow out quickly through the seepage hole 3. The fast flow rate of water in the seepage hole 3 will result in a large water consumption and poor unblocking effect. Moreover, using a large amount of water during unblocking will increase the burden on subsequent processes.

[0020] As an optional design, the preferred unblocking fixture for the fine material silo in the crushing workshop includes a sliding rod 4.8 fixedly connected to the bottom of the baffle 4.4, extending along the rotation path of the baffle 4.4, and a sliding sleeve 4.6 fixedly connected to the bottom of the partition 4.2, extending along the rotation path of the baffle 4.4. The sliding rod 4.8 and the sliding sleeve 4.6 are slidably connected. A compression spring 4.7 is provided inside the sliding sleeve. One end of the compression spring 4.7 is connected to the sliding rod 4.8, and the other end of the compression spring 4.7 is connected to the partition 4.2. When the sliding rod 4.8 slides along the sliding sleeve 4.6, the compression spring 4.7 accumulates or releases potential energy. It should be noted that, in order to achieve the purpose of opening and closing the through hole through the elastic connection between the baffle 4.4 and the partition 4.2, a torsion spring can also be sleeved on the hinge shaft 4.3, with one end of the torsion spring connected to the partition 4.2 and the other end connected to the baffle 4.4.

[0021] As an optional design, the preferred unblocking tool for the fine material bin in the crushing workshop is provided with handles 6 on the upper part of the extension tube 5 for easy gripping of the extension tube 5. In addition, a horizontal bar is inserted into the handles 6 of the extension tube extending out of the fine material bin to prevent the unblocking tool from falling into the bin after unblocking.

[0022] The working process of this utility model is as follows:

[0023] During operation, an opening is made at a suitable location above the fine material silo where space is limited. Several extension pipes 5 are sequentially connected to the upper end of the drainage pipe 2 as needed. The length of the unblocking tool can be freely adjusted by connecting multiple extension pipe sections 5 to solve blockages in fine material silos of various heights. Each extension pipe section 5 is relatively short, making it suitable for locations with limited space. The feed cone 1 is inserted into the material in the fine material silo, with the uppermost extension pipe 5 extending out of the silo. Water is introduced into the drainage pipe 2 and extension pipes 5 through the water inlet pipe. The water flow is adjusted according to the degree of material compaction, keeping it as small as possible to allow the water to slowly seep into the material. Ultimately, the material is scattered, thus clearing the blockage. After clearing, when it is necessary to remove the tool, the installation action is reversed, and the tooling disassembly extension pipe 5 is pulled out step by step. This utility model is a tooling for clearing blockages in the fine material silo of the crushing workshop. It is very convenient to use and can effectively solve the blockage phenomenon caused by the caking of ore materials, increase the volume of the fine material silo, enable the production equipment to operate normally and stably, and save equipment inspection and maintenance time. By reducing the downstream ball mill downtime by 1 hour per month, it can save the company 150,000 yuan in economic losses per year. Moreover, there are no dangerous factors in the use of this device, which can ensure the safety of personnel.

[0024] The above description is only an application implementation of this utility model, but the protection scope of this utility model is not limited thereto and cannot be used to limit the scope of rights of this utility model. Any equivalent changes made according to the technical solution of this utility model should be included within the protection scope of this utility model.
