Description

Technical Field

[0001] The utility model belongs to the technical field of ore energy, and particularly relates to a spiral coal washer. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip off the surface soil layer to mine coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. The scope of coal mines includes a large area above and below the ground and related facilities. Coal mines are reasonable spaces excavated by humans when excavating coal-rich geological strata, usually including tunnels, shafts, mining faces, etc.

[0003] Newly mined coal is raw coal, which is mixed with many harmful impurities. Direct combustion is not only inefficient, but also pollutes the environment and increases transportation costs. Therefore, coal washing is a necessary step for newly mined coal mines. It can wash away impurities such as mud in the coal mine through the impact of water flow, and can also distinguish the grade of raw coal according to different densities.

[0004] Chinese patent application number CN202222301276.6 discloses an energy-saving double-cylinder spiral coal washer, which includes a base, a bracket and an upper bracket. The bracket is fixedly installed above the base, and the upper bracket is fixedly installed above the bracket. A cleaning mechanism for rotating and cleaning coal and a filtering mechanism for filtering sewage are respectively provided above the base, and connecting rods are fixedly installed on both sides of the outside of one end of the rotating rod.

[0005] As the applicant conducted further research, it was found that since the technical solution failed to improve the structure of the spiral conveyor, although it could transport and clean the raw coal within a certain length range, it was not suitable for transporting and cleaning the raw coal over a longer distance. The reason was that the spiral conveyor structure was affected by its own weight, and there was a concave part in the middle part, and its length was subject to certain restrictions.

[0029] like Figure 1 - Figure 4 As shown, a spiral coal washer of the present invention comprises a frame 1, a spiral conveying assembly 2 and a lifting and adjusting assembly 3;

[0030] The upper end of the frame 1 is connected to a washing tank 10, and the end of the frame 1 is connected to a power component 4;

[0031] The screw conveying assembly 2 is placed in the washing tank 10 and is connected to the output end of the power assembly 4. Through the rotation of the screw conveying assembly 2, the raw coal placed in the washing tank 10 is transported and cleaned by the spray pipeline.

[0032] The spiral conveying assembly 2 includes a rotating shaft 20 and a spool 21 surrounding the rotating shaft 20 and distributed along the length direction of the rotating shaft 20;

[0033] The lifting and adjusting assembly 3 is arranged on the upper part of the screw conveying assembly 2. The lifting and adjusting assembly 3 includes a bracket 30 connected to both sides of the frame 1, a cross frame 31 slidably connected to the inner side of the bracket 30, and a screw 32 passing through the top of the bracket 30 is connected to the upper end of the cross frame 31. The end of the screw 32 is provided with a handle 33;

[0034] The bottom of the cross frame 31 is connected to an annular sleeve 34 that is sleeved on the outer periphery of the rotating shaft 20. A lifting and adjusting assembly 3 is set on the upper part of the spiral conveying assembly 2. By controlling the rotation of the screw 32, the cross frame 31 moves vertically along the inner side of the bracket 30, so that the annular sleeve 34 provides an upward supporting force to the rotating shaft 20, avoiding the concave middle part of the spiral conveying assembly 2 and limiting the layout length of the spiral conveying assembly 2.

[0035] Specifically, the annular sleeve 34 includes a pair of semicircular connecting blocks 340, and the side of the semicircular connecting blocks 340 is provided with side ears 341 for the fasteners 5 to pass through. When the lifting and adjusting assembly 3 needs to be installed, one of the semicircular connecting blocks 340 can be placed under the rotating shaft 20, and the other semicircular connecting block 340 located above the rotating shaft 20 can be aligned to form an annular sleeve 34 that is sleeved on the outer periphery of the rotating shaft 20, wherein the side ears 341 of each of the upper and lower semicircular connecting blocks 340 are provided with through holes, and fasteners 5, such as bolts, are used to pass the bolts through the paired side ears 341 to fasten them together.

[0036] By manually applying force to the handle 33 in a clockwise or counterclockwise direction, the screw 32 is controlled to rotate, thereby driving the cross frame 31 to rise or fall. This method has a simple structure and is highly feasible.

[0037] In order to reduce the friction between the rotating shaft 20 and the annular sleeve 34 and simultaneously realize the lifting support of the rotating shaft 20 , a bearing can be sleeved in the annular sleeve 34 .

[0038] In addition, guide grooves 300 are vertically opened on the inner walls on both sides of the bracket 30, and rollers (not shown in the figure) that cooperate with the guide grooves 300 are set at both ends of the cross frame 31. The setting of the guide grooves 300 and the rollers can prevent the cross frame 31 from shaking during the rising or falling process. Such a setting ensures the smooth movement of the cross frame 31 during the adjustment support.

[0039] The screw conveyor assembly 2 also includes several mounting bars 22 arranged parallel to and surrounding the rotating shaft 20. Connected to the inner sides of the mounting bars 22 are concentric rotors 23 that are sleeved onto the outer periphery of the rotating shaft 20. The arrangement of the mounting bars 22 and concentric rotors 23 ensures that adjacent shrouds 21 are evenly spaced and surround the outer periphery of the rotating shaft 20. During rotation, the shrouds 21 rotate together through this structural connection, thereby transporting the raw coal.

[0040] The twisted piece 21 includes a plurality of arc-shaped pieces 210 connected end to end, and each arc-shaped piece 210 is connected by a connecting block 211 and a bolt. The twisted piece 21 adopts a detachable connection method to facilitate subsequent maintenance and replacement.

[0041] The power assembly 4 is mainly composed of a motor and also includes a corresponding reduction box transmission structure.

[0042] The above are only embodiments of the present invention. Common knowledge such as the known specific structures and characteristics in the scheme is not described in detail here. Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date. Ordinary technicians in the relevant field can improve and implement this scheme based on their own abilities under the guidance of this application. Some typical known structures or methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the present utility model, they can also make several variations and improvements, which should also be regarded as the scope of protection of the present utility model. These will not affect the effect of the implementation of the present utility model and the practicality of the patent.
