Description

Technical Field

[0001] The utility model patent belongs to the technical field of phosphate ore stacking equipment, and specifically relates to a phosphate ore raw material stacking equipment. Background Art

[0002] Phosphate rock is a general term for phosphate minerals that can be used economically. It is an important chemical mineral raw material. It can be used to make phosphate fertilizers, and can also be used to make yellow phosphorus, phosphoric acid, phosphides and other phosphates for use in industrial sectors such as medicine, food, matches, dyes, sugar, ceramics, and national defense. Phosphate rock has been used in industry for more than 100 years. During the processing of phosphate rock, the raw materials of phosphate rock need to be crushed and screened. In this process, the initially crushed and screened phosphate rock will be put into the warehouse for accumulation so that it can be taken according to the amount later.

[0003] Existing phosphate ore stacking and reclaiming equipment mostly adopts semi-gantry scraper reclaimers and stacking areas. In the field of stacking and reclaiming equipment, for example, a Chinese patent (CN214398463U) discloses a comprehensive raw material warehouse transportation and storage equipment, which divides the material storage area into several units, and uses a mobile unloading vehicle to move and unload on the top of the warehouse, and can switch between the storage warehouse and the storage ore trough; it can also realize the full-length reclaiming of the storage warehouse bottom and the full-length reclaiming of the storage ore trough.

[0004] Although the above equipment has increased the material reclaiming method, it still has the same defects as the current semi-gantry scraper reclaiming: first, when the mobile unloading vehicle on the top of the silo unloads, due to its high unloading height, the material will fall very quickly. Therefore, when unloading, large particles of material will impact the bottom of the silo, and the long-term impact will damage the bottom surface of the silo, shortening the service life of the stacking area. At the same time, the damaged bottom surface of the silo will make it inconvenient for the scraper to reclaim materials; in addition, when the unloaded material is small-particle fine material, some of the material will be compacted and condensed on the bottom surface of the silo, which is easy to cause damage to the scraper. A small part of the material will splash with the airflow during the descent to form dust, thereby polluting the workshop environment. At the same time, the flying fine material will also cause a waste of resources.

[0005] In order to solve the above problems, this paper proposes a phosphate rock raw material stacking equipment. Utility Model Content

[0021] like Figures 1 to 4As shown, the prior art in this embodiment has the following problems: the inventors found that a comprehensive raw material storage equipment disclosed in the Chinese patent (CN214398463U) has increased the material taking method, but still has the same defects as the current semi-door scraper taking material: first, when the mobile unloading vehicle on the top of the silo unloads, because its unloading height is very high, the material will fall very fast, so when unloading, large particles of material will impact the bottom of the silo, and the long-term impact will damage the bottom surface of the silo, shortening the service life of the stacking area. At the same time, the damaged bottom surface of the silo will make it inconvenient for the scraper to take the material; in addition, when the unloaded material is small-particle fine material, some of the material will be compacted and condensed on the bottom surface of the silo, which is easy to cause damage to the scraper, and a small part of the material will splash with the airflow during the descent process to form dust, thereby polluting the workshop environment. At the same time, the flying fine material will also cause a waste of resources;

[0022] Therefore, the inventor provides a phosphate ore raw material stacking equipment, including a semi-gantry scraper reclaimer 1, a traveling mechanism, a stacking area 2, an elevated frame 3, and a mobile unloading vehicle 4. The semi-gantry scraper reclaimer 1 is obliquely installed on the stacking area 2 through an upper traveling mechanism A5 and a lower traveling mechanism A6. The elevated frame 3 is installed in the center of the stacking area 2, and the mobile unloading vehicle 4 is installed on the top of the elevated frame 3.

[0023] Its principle and effect are as follows: when the device is in use, the control base 9 can control the receiving bin 15 of the semi-gantry receiving machine in real time to correspond to the position directly below the unloading point of the mobile unloading vehicle 4, thereby catching the ore falling from the high altitude and discharging it from the unloading buffer device. In this way, the secondary receiving and unloading of the ore can reduce the impact of the ore on the bottom of the bin in the stockpiling area 2. At the same time, the buffer bag 19 in the unloading buffer device can also reduce dust diffusion and avoid pollution to the air environment of the workshop. Example 2

The winding drum 2 The rear side of 2 is connected to the driving end of the driving motor 21, and the driving motor 21 is installed on the base 17; during the use of this structure, the driving motor 21 can drive the winding drum 22 to pull up and then lower the pull rope 23, and then cooperate with the knot 24 and the limit plate 20, so as to control the working length of the buffer bag 19. This structure can reduce the impact of the mineral material on the bottom of the warehouse in the stacking area 2. At the same time, the buffer bag 19 in the material unloading buffer device can also reduce dust diffusion and avoid pollution to the air environment of the workshop.
