Description

Technical Field

[0001] The present invention relates to the technical field of metallic silicon, in particular to a pulverizer for metallic silicon and a use method thereof. Background Art

[0002] Metallic silicon is also called crystalline silicon or industrial silicon. Its main use is as an additive for non-ferrous alloys. Metallic silicon is a product smelted from quartz and coke in an electric furnace. The content of the main component silicon is about 98%. In the preparation process of high-purity silicon, purification is a necessary step. There are many existing purification methods, such as physical methods, including directional solidification, slag making, etc., chemical methods such as pickling and oxidation, but no matter which purification method is used, the raw materials need to be crushed; A metal silicon pulverizer described in the patent application with publication number CN113245036B comprises: a housing and a pulverizing box, wherein the pulverizing box is arranged inside the housing; a supporting mechanism, wherein the supporting mechanism is arranged between the pulverizing box and the housing; and a pulverizing mechanism, wherein the pulverizing mechanism is connected to the pulverizing box and is used to cooperate with the pulverizing box to pulverize the metal silicon and cooperate with the supporting mechanism to move the pulverizing box; wherein the pulverizing mechanism comprises: a pulverizing assembly, wherein the pulverizing assembly is arranged inside the pulverizing box and is rotatably connected to the housing; a driving assembly, wherein the driving assembly is connected to the pulverizing box; and an air guide assembly, wherein the air guide assembly is arranged between the pulverizing assembly and the driving assembly; When the metal silicon blocks are crushed, when a large number of metal silicon blocks are put into the crusher in batches, they are easy to be blocked in the feed port, affecting the crushing effect of the metal silicon. Using vibration to push them apart and let them fall evenly will cause the non-metallic silicon particles attached to the surface of the metal silicon to fall into the crushing collection box along with the vibration, resulting in a decrease in the purity of the silicon powder after the metal silicon is crushed.

[0006] Preferably, the interior of the feed box is connected to the interior of the crushing box, the interior of the crushing box is connected to the interior of the crusher, and a fixing ring is fixedly connected to the outer wall of the feed barrel.

[0007] Preferably, a collecting plate is fixedly connected to the top of the fixing ring, a filter screen is fixedly connected to the inner wall of the collecting plate, and the interior of the filter screen is connected to the interior of the collecting plate.

[0008] Preferably, the interior of the collecting tray is connected to the interior of the feeding barrel, the interior of the filter screen is connected to the exterior of the collecting tray, and an auxiliary mechanism is provided on the outer wall of the toggle plate.

[0009] Preferably, the auxiliary mechanism comprises a fixing sleeve, an inner wall of the fixing sleeve is fixedly connected to an outer wall of the threaded rod, a spring is fixedly connected to one side of the fixing sleeve, and an internal threaded ring is fixedly connected to one end of the spring.

[0010] Preferably, the outer wall of the inner threaded ring is fixedly connected to a toggle rod, the outer wall of the inner threaded ring is rotatably connected to a bearing sleeve, the inner wall of the bearing sleeve and the outer wall of the threaded rod are slidably connected via a slider, the top of the bearing sleeve is rotatably connected to a rotating ball A, the outer wall of the rotating ball A is fixedly connected to a hinged rod, one end of the hinged rod is fixedly connected to a rotating ball B, the outer wall of the rotating ball B is rotatably connected to a sliding block, and the inner wall of the sliding block is slidably connected to a fixed bar.

[0012] A brushless motor rotor magnetizing device comprises the following steps: Step 1: When in use, put the metal silicon block for metal silicon into the feed barrel, and then it falls into the feed box along the inclined surface of the inner wall of the feed barrel; The second step: the metal silicon blocks are fed into the crushing box through the feed box and crushed by the crushing rollers in the crusher to complete the crushing of the metal silicon blocks.

[0013] Step 3: When the metal silicon block is put into the feed barrel, the motor is started to control the rotation of the shaft. The shaft drives the threaded rod and the toggle plate to rotate synchronously. When the toggle plate rotates, it drives the feed box to rotate. The feed box rotates on the top of the feed box through the bearing ring below, and the threaded rod breaks up the falling silicon blocks.

[0014] The present invention provides a metal silicon pulverizer and a method of using the same. The invention has the following beneficial effects: 1. The present invention provides a crushing and separation mechanism. As the inclined surface of the inner wall of the feed barrel is evenly pushed by the threaded rod to slide down and enter the feed box for crushing, the uniform falling of the metal silicon blocks is ensured. At the same time, through the rotation of the feed barrel and the toggle plate, the air between each toggle plate is centrifugally pushed outward and upward by the rotation of the toggle plate, so as to complete the separation of the floating dust particles mixed in the metal silicon blocks, and avoid the problem that a large amount of dust particles of non-metallic silicon blocks adhere to the metal silicon blocks due to transportation and other reasons, and are put into the crushing and collection together.

[0015] 2. The present invention sets a crushing and separation mechanism, and the air is moved by the feed box to form an outward discharge of air through the filter, thereby forming an outward discharge of air inside the feed barrel, thereby completing the outward discharge of air and dust particles mixed in the silicon block. The air is discharged through the filter, and the dust particles are filtered and blocked by the filter, while the isolated particles and dust naturally fall on the inner wall of the collection plate, thereby completing the automatic separation and collection of small particles in the silicon block and the silicon block.

[0016] 3. The present invention sets an auxiliary mechanism. When the internal thread ring slides outward on the threaded rod and rotates, it will drive the toggle rod on the outer wall to rotate synchronously, so as to utilize the rotation of the toggle rod to realize continuous up and down toggle of a large number of metal silicon blocks in the feed box, which will further enhance the effect of breaking up the metal silicon blocks. While improving the falling efficiency, the metal silicon blocks are also knocked, so that the residue and dust attached to the surface of the metal silicon blocks are fully knocked off, thereby separating from the outer wall of the metal silicon blocks, and then the toggle plate drives the airflow to take away the lighter particles and dust, thereby improving the crushing purity of the metal silicon blocks and reducing the influence of dust impurities.

[0017] 4. The present invention sets an auxiliary mechanism. When the threaded rod rotates at a faster speed for rapid material discharge and separation of dust particles, the ventilation groove can be opened more, so that the area of ​​the air moved by the toggle plate decreases as the rotation speed increases, thereby avoiding the problem of smaller silicon blocks being collected into the collection plate together due to excessive airflow inside the feed barrel when the toggle plate rotates faster. The toggle plate is kept to move a certain amount of air at different rotation speeds to form a stable airflow to carry away dust particles of a specified size, thereby minimizing the rate of air discharge due to the different rotation speeds of the threaded rod and the feed barrel, thereby maintaining the stability of the separation work.
