[0052] In the application, the meshing assembly comprises a gear ring 17 and a fixed gear 16, a pair of first bearings are arranged on the top of the inner two side walls of the bottom box 1, the two ends of the driving shaft 12 are respectively inserted into the corresponding first bearings, and the left end of the driving shaft 12 penetrates the bottom box 1 and extends to the outside of the bottom box 1; a pair of concentrically and fixedly arranged channel steel rings are sleeved on the two sides of the hollow cylinder 2 between the pair of outer rings 21, a gear ring 17 is concentrically and fixedly sleeved on the outer side of each channel steel ring, a pair of concentrically and fixedly arranged fixed gears 16 are sleeved on the two sides of the driving shaft 12 in the bottom box 1, and each fixed gear 16 is meshingly connected with the corresponding gear ring 17; since the number of teeth of the gear ring 17 is more than the number of teeth of the fixed gear 16, when the fixed gear 16 reversely rotates, the meshing drives the gear ring 17 and the hollow cylinder 2 to slowly rotate in the positive direction along the bearing ring 22.

[0053] In the present invention, a concentrically fixed driven gear 15 is sleeved on the middle part of the driving shaft 12, and a rectangular through hole is opened on the top surface of the bottom box 1 above the driven gear 15.

The left end of the horizontal axis 23 is inserted into the second bearing and extends to the outside of the bottom box 1. The inner wall of the hollow cylinder 2 is divided into a grinding part, a sieve hole part, and a smooth part from left to right.

The smooth part is evenly provided with a number of scraping blades 28 that are continuously spirally fixed on the horizontal axis 23. The hollow cylinder 2 is in a slow forward rotation and the horizontal axis 23 is in a reverse rotation. When the raw material passes through the grinding part, the granular raw material is squeezed and crushed by the cooperative extrusion of the grinding protrusion 25 and the wear-resistant protrusion 29. When the raw material passes through the sieve hole part, the raw material is crushed under the action of the crushing cutter 26, and the crushed raw material falls to the bottom of the bottom box 1 along the sieve hole 27. When the raw material passes through the smooth part, the scraping blade 28 rotates in the reverse direction, driving the raw material to continue to be crushed to the left.

[0055] In the present invention, a concentrically fixed first pulley 34 is sleeved on the left end portion of the drive shaft 12 located on the outside of the bottom box 1, and a pair of concentrically fixed linkage pulleys 36 are sleeved on the left end portion of the transverse shaft 23 located on the outside of the bottom box 1. The first pulley 34 is transmission-connected to a linkage pulley 36 through a first belt 35. When the first pulley 34 rotates, a linkage pulley 36 and the transverse shaft 23 are driven to rotate synchronously through the first belt 35; a concentrically fixed second pulley 38 is sleeved on the left end portion of the spiral shaft 3 located on the outside of the bottom box 1, and the second pulley 38 is transmission-connected to another linkage pulley 36 through a second belt 37. The other linkage pulley 36 drives the second pulley 38, the spiral shaft 3 and the spiral blade 31 to rotate synchronously through the second belt 37.

[0056] In the present invention, a slag discharge barrel 32 is provided on the right side of the bottom box 1 at a position corresponding to the bottom of the right port of the hollow barrel 2, and the outer port of the slag discharge barrel 32 is sleeved with a first sealing cover with a threaded connection, and a discharge barrel 33 is provided on the bottom of the right side of the bottom box 1, and the outer port of the discharge barrel 33 is sleeved with a second sealing cover with a threaded connection, and movable wheels are provided at the four corners of the bottom surface of the bottom box 1; the first sealing cover and the second sealing cover are opened in turn, and impurities are discharged along the slag discharge barrel 32 under the action of the scraping blade 28, and the raw materials are discharged along the discharge barrel 33 under the action of the spiral blade 31.

[0057] Example 3: In this example, the specific use of production equipment includes the following steps:

[0058] Step 1: Start the motor 13. The motor shaft end of the motor 13 drives the driving gear 14 to rotate synchronously, meshing and driving the driven gear 15 and the drive shaft 12 to rotate in the opposite direction, thereby driving the fixed gear 16 and the first pulley 34 to rotate in the opposite direction. Since the number of teeth of the gear ring 17 is greater than that of the fixed gear 16, when the fixed gear 16 rotates in the opposite direction, the meshing drives the gear ring 17 and the hollow cylinder 2 to rotate slowly in the forward direction along the bearing ring 22.

[0059] Step 2: When the first pulley 34 rotates in the opposite direction, the first belt 35 drives a linkage pulley 36 and the horizontal shaft 23 to rotate in the opposite direction synchronously. Since the horizontal shaft 23 is eccentrically arranged at the bottom of the hollow cylinder 2, when the horizontal shaft 23 rotates in the opposite direction, it drives the grinding roller 24, the crushing cutter 26, and the scraping blade 28 to rotate in the opposite direction in sequence; another linkage pulley 36 drives the second pulley 38 and the spiral shaft 3 to rotate in the opposite direction through the second belt 37, and drives the spiral blade 31 to rotate in the opposite direction synchronously;

[0060] Step 3: During the above operation, the hollow cylinder 2 is in a slow forward rotation, the horizontal axis 23 is in a reverse rotation, and the granular raw material is poured into the hollow cylinder 2 through the feed channel steel 39. When the raw material passes through the grinding part, the granular raw material is squeezed and crushed by the cooperation and extrusion of the grinding protrusion 25 and the wear-resistant protrusion 29; when the raw material passes through the sieve hole part, the raw material is crushed under the action of the crushing reamer 26, and the crushed raw material falls to the bottom of the bottom box 1 along the sieve hole 27; when the raw material passes through the smooth part, the scraper blade 28 rotates in the reverse direction, driving the raw material to the left to continue to be crushed;

[0061] When the hollow cylinder 2 rotates forward, the horizontal shaft 23 rotates in the reverse direction. The eccentric design of the horizontal shaft 23 in the hollow cylinder 2 drives the grinding roller 24, the crushing cutter 26, and the scraping blade 28 to work synchronously with the eccentric action, which causes the raw materials to turn over in the hollow cylinder 2, achieving the effect of vibrating the screen, and drives the raw materials to fall to the bottom of the bottom box 1 along the sieve holes 27, and the impurities temporarily remain in the hollow cylinder 2;

[0062] Step four, when the raw material in the hollow cylinder 2 is crushed, only the large particle impurities are left in the hollow cylinder 2, the qualified raw material falls to the bottom of the bottom box 1, then the motor 13 is controlled to rotate reversely, the hollow cylinder 2 is driven to rotate reversely slowly, the horizontal shaft 23 is driven to rotate forwardly, and the spiral shaft 3 is driven to rotate forwardly;

[0063] Step five, the first sealing cover and the second sealing cover are opened in sequence, the impurities are discharged along the smooth part of the hollow cylinder 2 and the slag discharge cylinder 32 under the action of the wall scraping blade 28, and the raw material is discharged along the discharge cylinder 33 under the action of the spiral blade 31.

[0064] The application can effectively shorten the refining time and improve the production efficiency of the silicon calcium manganese deoxidizer by reasonable material design of the silicon calcium manganese deoxidizer, and the finished product rate is further improved by the use of the production equipment to effectively remove the impurities of the silicon calcium manganese deoxidizer during production.

[0065] The above is only the preferred specific implementation of the application, but the protection scope of the application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the application within the technical range disclosed by the application, which should be covered in the protection scope of the application.
