Description

Technical Field

[0001] The utility model belongs to the technical field of mineral processing, and particularly relates to a screening device for raw materials in a mine. Background Art

[0002] Ore refers to the stones containing certain valuable minerals mined from mines. After being processed step by step such as crushing and grinding, ores can be applied in engineering fields such as metal mines, metallurgical industries, chemical industries, construction industries, iron and highway construction units, cement industries, and sand and gravel industries. When people process ores, they all have to perform the step of screening and separating the ores.

[0003] In the current ore screening process, generally, multiple parallel railings are arranged at the bottom discharge port of the ore bin to roughly screen the ores. This screening device is too rough and can only roughly remove oversized ore fragments. The production personnel on the subsequent production line still need to manually discharge some fragments, reducing the work efficiency of the production personnel. Content of the Utility Model

[0028] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0029] As Figures 1-3 shown, a screening device for mine raw materials according to the present utility model includes a chassis 1. At both ends of the lower side of the crushing assembly 101, a semi-circular through groove is provided on the chassis 1, and a coarse ore screening leak box 2 is slidably connected thereto. The lower side of the coarse ore screening leak box 2 is semi-circular arc-shaped and is provided with a plurality of leak holes 2001. Baffle plates 201 are connected to both ends of the coarse ore screening leak box 2. A motor is connected to the outer wall of the coarse ore screening leak box 2, and the output end of the motor is connected to a drive rod 3. A plurality of driving rods 301 are connected to the outer wall of the shaft body of the drive rod 3, and the end of a single driving rod 301 is in contact connection with the bottom of the inner wall of the coarse ore screening leak box 2;

[0030] The outer wall of the chassis 1 is connected to a water storage tank 4. A water pump is provided in the water storage tank 4. The output end of the water pump is connected to a spray head 402 through a plurality of transmission pipes 401. Both sides of the inner wall of the chassis 1 are connected to a spray chamber 5 at a certain inclination angle, and a plurality of spray heads 402 are respectively connected in the spray chambers 5 on both sides;

[0031] An operation door 102 is provided on one side of the chassis 1. A second sieve plate 6 is detachably connected to the lower side of the coarse ore screening leak box 2 on the inner wall of the chassis 1. The second sieve plate 6 includes an edge sieve plate 601 and an intermediate sieve plate 602 that are spliced.

[0032] In the embodiment of the present case, the ore raw material enters the interior of the chassis 1 from the feed tube of the chassis 1, first falls between the crushing components 101 for crushing, and after crushing, it falls into the coarse ore screening leak box 2. The still relatively large pieces of ore after crushing remain in the coarse ore screening leak box 2. The finely crushed ore and ore powder leak from the leakage holes 2001 of the coarse ore screening leak box 2 to the second sieve plate 6 for secondary filtration. The finely crushed ore remains on the upper side of the second sieve plate 6, and the ore powder directly leaks out from the discharge port of the chassis 1 for collection. Such a structural design can achieve the effect of automatically screening out coarse ore raw materials, finely crushed ore raw materials, and ore powder, and improve the screening accuracy;

[0033] Among them, when the ore raw material passes through the coarse ore screening leak box 2, due to the semi-circular arc shape of the coarse ore screening leak box 2, most of the ore raw materials leak to the middle of the inner wall of the coarse ore screening leak box 2. At this time, the motor is turned on. The motor drives the transmission rod 3 to rotate. When the transmission rod 3 rotates, it drives each driving rod 301 to rotate. When the driving rod 301 rotates, it pushes the internal ore raw materials to change their positions again, so that some of the missed finely crushed ore leaks through the leakage holes 2001 of the coarse ore screening leak box 2, improving the screening efficiency. When it is necessary to clean the large pieces of ore in the coarse ore screening leak box 2, the coarse ore screening leak box 2 can be pulled out of the chassis 1 to collect the large pieces of ore raw materials;

[0034] In addition, dust will be generated during screening after crushing. The water pump in the water storage tank 4 is turned on, and the water pump sprays water in cooperation with the plurality of transmission pipes 401 and the spray heads 402 to achieve the effect of suppressing most of the dust, thereby improving the air quality of the processing environment. The edge sieve plate 601 and the intermediate sieve plate 602 are spliced, which can facilitate subsequent replacement and repair of the corresponding edge sieve plate 601 or intermediate sieve plate 602 at a single position. When it is necessary to clean and collect the finely crushed ore on the second sieve plate 6, the operation door 102 on one side of the chassis 1 can be opened for collection. The structure is simple and easy to operate, improving the processing efficiency.

Such a structural design facilitates the rapid and stable installation and removal of the coarse ore screening leakage box 2. In fact, other structural shapes that are convenient for installing and removing the coarse ore screening leakage box 2 can also be considered according to specific circumstances.

[0036] Preferably, a protective baffle 501 is connected to the upper side of the open end of the spray chamber 5. Such a structural design prevents the spray head 402 from being damaged when the ore falls, thereby extending the service life of the spray head 402. In fact, other structural shapes for protecting the spray head 402 can also be considered according to specific circumstances.

[0037] Preferably, the plurality of driving rods 301 are connected with mounting sleeves 302, the mounting sleeves 302 are sleeved on the outer wall of the shaft body of the transmission rod 3, and a plurality of first bolts are connected between the mounting sleeves 302 and the transmission rod 3.
