Description

Technical Field

[0001] The invention relates to the technical field of chemical raw material production, in particular to a lithium sulfate clinker crushing device with adjustable particle size. Background Art

[0002] Lithium sulfate is a chemical with the appearance of colorless monoclinic crystals or white crystalline powder. It is soluble in water but insoluble in acetone and anhydrous ethanol. It is usually stable and is usually used as special glass or some pharmacological reagents. However, lithium sulfate is usually in the form of block crystals, which is not convenient to store. Once it deteriorates, more raw materials will be wasted. During use, block lithium sulfate also has many inconveniences, so it needs to be crushed into powder particles for easier storage and use.

[0003] Since the use of lithium sulfate usually requires a relatively high purity and its particle size needs to be precisely controlled, ordinary grinding equipment is not competent for this purpose. In existing crushing devices, an auger or the like is usually used to hit the lithium sulfate clinker to complete the crushing operation. There are countless devices using this structure. For example, Chinese utility model patent CN221433309U discloses a lithium sulfate clinker crushing and grinding device, which uses the above method to process lithium sulfate. However, the particle size of the lithium sulfate processed in this way cannot be precisely controlled, and the degree of internal crushing cannot be known during the processing. It is easy to cause excessive grinding, resulting in the problem of heat deterioration of the product. Summary of the invention

A program control box is provided, in which the crushing time and crushing power are input, and then the lithium sulfate clinker is fed into the feed box, which will extrude and convey the lithium sulfate clinker into the crushing box, and the crushing motor will start, and the scattering mesh cover will scatter the incoming lithium sulfate clinker. Under the action of the reduction box, the crushing rod will rotate, and the crushing assembly on the crushing rod will rotate accordingly to crush the lithium sulfate clinker. At the same time, the feedback disk will rotate in the opposite direction of the crushing rod to increase the fluidity of the lithium sulfate clinker and provide timely feedback on the fluidity of the lithium sulfate clinker. The crushed lithium sulfate clinker will pass through the filter screen into the bottom of the crushing box and be discharged from the discharge port to complete the crushing.

[0006] A surging motor is arranged on the feed box, and a surging screw is arranged on the output end of the surging motor. The surging screw is rotatably connected to the feed box. A plurality of surging rods are arranged in the feed box, and crushing hammers are arranged at both ends of the surging rods. Each surging rod is rotatably connected to the feed box through a rotating shaft, and each crushing hammer is in intermittent sliding contact with the threads on the surging screw. A dispersion net is arranged on the feed box, and the dispersion net is connected to the feed port. When feeding, the surging motor will drive the surging screw to rotate, and at the same time, the lithium sulfate clinker is fed into the feed box. The surging screw will drive the lithium sulfate to move. During the movement, the threads on the surging screw will squeeze the crushing hammer. After being squeezed, the crushing hammer will rotate. Under the action of the surging rod, the crushing hammer away from the squeezed crushing hammer will deflect toward the direction of the surging ring screw, so as to achieve the impact and crushing of the lithium sulfate clinker, reduce the blockage, and achieve the effect of preliminary crushing of the lithium sulfate clinker.

[0007] A plurality of breaking rods are arranged on the breaking net cover, each breaking rod is rotatably connected to the crushing rod at one end close to the crushing motor, a centrifugal ball is arranged on the breaking rod, a sliding ring is arranged at one end of the breaking rod away from the crushing motor, the sliding ring is slidably connected to the breaking net cover, and each breaking rod is rotatably connected to the sliding ring. When the crushing rod rotates, the lithium sulfate clinker will fall on the breaking net cover, and the breaking rod will hit the lithium sulfate clinker to make it more evenly dispersed, and under the action of the centrifugal ball, the breaking rod will expand, and the breaking rod can crush large pieces of lithium sulfate clinker by means of elastic force and centrifugal ball, while avoiding the problem of adhesion of lithium sulfate clinker and reducing the possibility of adhesion and deterioration, which leads to contamination of lithium sulfate raw materials.

[0008] The crushing assembly includes a crushing ring, which is sleeved on the crushing rod and fixedly connected by screws. A plurality of tool mounting grooves are installed on the crushing ring, each of which is rotatably connected to the crushing ring, and a crushing tool is installed on each tool mounting groove, which is fixedly connected to the tool mounting groove by a plurality of screws. Before crushing the lithium sulfate clinker, it is necessary to select the specifications of the crushing tool, and then install the crushing tool in the tool mounting groove, lock it with screws, and adjust the position of the crushing ring. During the crushing process, the crushing tool will crush the lithium sulfate clinker and also cause the lithium sulfate clinker to roll.

[0009] A plurality of surging protrusions are arranged on the feedback disk, a reversing gear set is arranged in the crushing box, a transmission tooth is arranged at the bottom end of the crushing rod, the reversing gear set is meshed with the transmission tooth on the crushing rod, the feedback disk is meshed with the reversing gear set, and a plurality of squeezing rollers are rotatably connected to the feedback disk. During the crushing process, the crushing rod drives the feedback disk to rotate through the reversing gear set, and its rotation direction is opposite to that of the crushing tool. The surging protrusions can increase the amplitude of the tumbling action of the lithium sulfate clinker, and the squeezing rollers on the feedback disk stir the lithium sulfate clinker and can also clean the filter holes on the filter screen to reduce the problem of blockage.

A sensing switch is provided in each sensing slot, and each sensing switch is electrically connected to the reduction gearbox through a wire. When the feedback disk is rotating, the detection wedge on the sensing slot will be squeezed by the flowing lithium sulfate clinker and fall on the sensing switch under the restriction of the spring shaft. When the triggering frequency of the sensing switch increases, it proves that the degree of crushing of the lithium sulfate clinker is high. At this time, it is necessary to speed up the rotation speed of the crushing tool, which can reduce the problem of lithium sulfate clinker sinking to the bottom, and at the same time, it can also speed up the crushing process, and can also fully protect the crushing tool and increase the service life of the crushing tool.

In addition, the lithium sulfate clinker entering the crushing box is dispersed in conjunction with the breaking structure, thereby avoiding the problem of excessive accumulation of lithium sulfate clinker.

[0015] 2. The present invention adopts a structural component that can detect the fluidity of lithium sulfate clinker, which can provide timely feedback on the degree of crushing, thereby adjusting the crushing speed and reducing the powder of lithium sulfate clinker caused by excessive shearing. At the same time, the structure of the feedback disk can also be used to churn the lithium sulfate clinker to enhance the crushing effect.
