Description

Technical Field

[0001] The utility model belongs to the technical field of lime production equipment, in particular to a crushing device for producing slaked lime. Background Art

[0002] Slaked lime, also known as slaked lime, is made by the reaction of quicklime and water. Its saturated aqueous solution is called lime water. It is a commonly used building material and is also used as a fungicide and chemical raw material. Limestone can be directly processed into stone and burned into quicklime. In the process of manufacturing quicklime, since the raw materials for manufacturing quicklime are usually large block structures, the raw materials of quicklime need to be crushed when manufacturing quicklime to facilitate further processing of the raw materials of quicklime.

[0003] The Chinese utility model patent with publication number CN210449344U discloses a lime crushing device with good crushing effect, including a fixed plate, a fixed column fixedly connected to the top of the fixed plate, a crushing shell fixedly connected to the top of the fixed column, a feed port opened on the left side of the top of the inner wall of the crushing shell, and a feed hopper matched with the feed port fixedly installed on the top of the crushing shell. The utility model fully crushes limestone and improves the crushing efficiency of the device through the cooperation of the crushing shell, the crushing motor, the crushing shaft, the crushing roller, the first crushing tooth, the second crushing tooth, the support plate, the crushing shell, the crushing wheel, the drive motor, the drive shaft, the crushing roller, the crushing teeth and the conveyor belt.

[0004] However, the above utility model still has some shortcomings:

[0005] 1. During the use of the utility model, the preliminarily crushed limestone enters the crushing shell from the crushing shell and falls on the left side of the crushing roller for further crushing, while the crushed limestone accumulates on the left side of the crushing roller, which makes the crushing strength of the crushing teeth on the left side of the crushing roller higher than that on the right side, resulting in higher wear of the crushing teeth on the left side than on the right side, which is not conducive to the crushing efficiency of the crushing teeth on the left side, and increases the maintenance frequency of the crushing roller on the other hand;

[0006] 2. During the use of the above utility model, the lime powder falls onto the conveyor belt after being crushed by the crushing roller and is collected through the conveyor belt. During the transportation of the lime powder on the conveyor belt, part of the lime powder will be adsorbed on the surface of the conveyor belt. This small amount of lime powder will fall to the bottom of the crushing shell during transportation. A lot of lime powder will accumulate for a long time, causing unnecessary waste. Utility Model Content

[0007] The utility model provides a crushing device for producing slaked lime, aiming to solve the problem mentioned in the above background technology that limestone initially crushed in the utility model during use will accumulate on the left side of a crushing roller, resulting in higher loss on the left side of the crushing roller than on the right side and lime powder adsorbed on a conveyor belt being difficult to remove.

[0008] The utility model is realized in this way: a crushing device for producing slaked lime comprises a crushing box and a pulverizing box installed at the side wall of the crushing box, a main crushing assembly is installed at the central position in the crushing box, and a side crushing assembly is installed on the inner wall of the crushing box, and the side crushing assembly cooperates with the main crushing assembly to crush limestone.

[0009] Preferably, a crushing assembly is installed obliquely in the crushing box, and the crushing assembly includes no less than two crushing columns, the crushing columns are installed obliquely on the inner wall of the crushing box, each crushing column is connected to a crushing motor at one end away from the crushing box, a fixed column is arranged in parallel between every two crushing columns, the fixed column is installed obliquely on the inner wall of the crushing box, a plurality of grinding blocks 1 are fixedly connected to the side walls of the crushing column and the fixed column, and a grinding block 2 is fixedly connected to the side wall of the crushing box close to the curved surface of the crushing column; in this scheme, the crushed limestone falls on the inclined fixed column, and in the process of the crushing column rotating to grind the limestone fragments, the limestone will roll evenly on the crushing column due to its own gravity, thereby ensuring the overall working strength of the crushing column.

[0010] Preferably, the main crushing assembly includes a crushing column, the top of which is connected to a crushing motor, the bottom of which is rotatably connected to a base, the base is fixedly mounted on the inclined surface of the bottom of the crushing box, the side wall of the crushing column is fixedly connected to a fixed block, and the side wall of the fixed block is fixedly connected to a plurality of main crushing spikes and main protrusions in sequence from top to bottom.

[0011] Preferably, the side crushing assembly includes a connecting block, which is fixedly connected to the inner wall of the crushing box, and a plurality of auxiliary crushing thorns corresponding to the main crushing thorns are fixedly connected to the side wall of the connecting block; in this scheme, the auxiliary crushing thorns cooperate with the main crushing thorns to perform preliminary crushing of limestone.

[0012] Preferably, a mounting block is fixedly connected to the side wall of the connecting block, and a secondary protrusion corresponding to the main protrusion is fixedly connected to the side wall of the mounting block; in this solution, the secondary protrusion cooperates with the main protrusion to perform preliminary grinding on the crushed limestone.

[0013] Preferably, a baffle is obliquely fixed on the inner wall of the crushing box, the baffle is arranged below the crushing column, and a conveyor belt is arranged below the baffle, and a discharge brush is closely arranged below the conveyor belt; in this scheme, the lime powder adsorbed on the surface of the conveyor belt is brushed off into the collection box by the discharge brush.

[0014] Preferably, a collecting box is arranged on the side of the crushing box, a passage opening 1 is opened between the crushing box and the crushing box, a passage opening 2 is opened between the crushing box and the collecting box, and the conveyor belt passes through the passage opening 2 and extends into the collecting box.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The limestone crushed by the main crushing assembly enters the crushing box through the channel opening 1 and falls on the inclined crushing column. When too much limestone fragments are accumulated on the left side of the crushing column, the limestone fragments will roll to the right due to their own gravity, so that the limestone fragments are evenly distributed on the crushing column, ensuring that the crushing strength at each position is roughly the same during the crushing of the limestone fragments by the crushing column, ensuring the overall working strength of the crushing column;

[0017] 2. The position where the main crushing spikes are connected on the side wall of the fixed block is inclined, and the auxiliary crushing spikes on the connecting block make the passage of limestone in the crushing box gradually narrow from top to bottom, ensuring that only small pieces of limestone can pass through the passage after being crushed, which plays a screening role for the crushed limestone and ensures that no large pieces of limestone will enter the crushing box, which will bring a greater burden to the work of the crushing column;

[0018] 3. A brush is installed at the bottom of the conveyor belt. The bristles of the brush are in close contact with the surface of the conveyor belt to ensure that the lime powder adhering to the surface of the conveyor belt is brushed off to prevent the lime powder from falling to the bottom of the crushing box and causing waste.
