[0014] Furthermore, the batching equipment of blast furnace slag silicate cement has the following steps:

[0015] S1: When in use, pour the prepared slag into the feed hopper, and the slag will enter the conical barrel in the batching box along with the feed hopper, and then start the drive motor, which drives the reciprocating screw to rotate, and the reciprocating screw drives the inclined plate and the conical barrel to rotate. Since some slag is heavier, the centrifugal force generated by the conical barrel during rotation has no obvious effect on the heavier slag. The inclined plate will throw out the slag that falls on the conical barrel during rotation. Under the centrifugal force of the rotation of the conical barrel, the heavier ore will be thrown out by the inclined plate and hit several strip plates. The strip plates will generate a reaction force on the slag, causing the slag to break. The broken slag will move upward along the inclined surface of the conical barrel under the centrifugal force of the conical barrel and the inclined plate. The broken slag will leave the conical barrel through the gap between the support rods. After hitting the support rods, the larger slag will be left in the conical barrel by several support rods for further crushing.

[0016] S2: The inclined plate and the conical cylinder will also discharge impurities from the conical cylinder through several impurity removal holes during the rotation process. The impurities on the inner wall of the conical cylinder will be discharged through the impurity removal holes on the inner wall of the bottom of the conical cylinder. The impurities rotating along the inclined surface of the conical cylinder will be discharged from the impurity removal holes on the inner wall of the conical cylinder. The discharged impurities will fall into the rectangular collection box, and then will be discharged out of the batching box along with the two rectangular collection boxes. Some of the slag leaving the conical cylinder will fall back to the top of the rectangular impurity discharge pipe. During the rotation of the conical cylinder, the two fixed L-shaped plates will be driven to rotate, the fixed L-shaped plates will drive the triangular annular plates to rotate, the triangular annular plates will drive the rectangular boxes to rotate, the rectangular boxes will drive the cleaning springs to rotate, and the cleaning springs will drive the triangular plates to rotate. During the rotation of the triangular plates, they will contact the rectangular impurity discharge pipe and produce collisions. The vibrations produced by the collisions will vibrate the impurities in the rectangular impurity discharge pipe.

[0017] S3: After the triangular plate contacts the rectangular impurity discharge pipe, the triangular plate will slide upward under the action of its inclined surface. The rise of the triangular plate will cause the cleaning spring to be compressed and deformed. As the triangular plate rotates continuously, the bottom of the triangular plate will contact the top of the rectangular impurity discharge pipe. In the process of passing through the top of the rectangular impurity discharge pipe, the triangular plate will drive the slag on the top of the rectangular impurity discharge pipe to leave the top of the rectangular impurity discharge pipe. After the triangular plate leaves the rectangular impurity discharge pipe, the slag will fall onto the conical crushing cylinder under the action of gravity. In the process of the triangular plate repeatedly hitting and passing through the rectangular impurity discharge pipe, the triangular plate will continuously vibrate. After the triangular plate takes away the slag on the top of the rectangular impurity discharge pipe, the slag that is not taken away by the inclined surface of the rectangular impurity discharge pipe will slide to the inner wall of the batching box, providing conditions for the next round of triangular plate cleaning;

[0018] S4: During the continuous rotation of the reciprocating screw, the reciprocating screw will drive the hollow conical extrusion block to move up and down, and the reciprocating screw will also drive the conical crushing barrel to rotate. During the descent of the hollow conical extrusion block, it will contact and crush the slag and a small amount of impurities that fall on the conical crushing barrel. Under the pressure of the hollow conical extrusion block, the slag will become stationary. Under the action of the rotation of the conical crushing barrel, the slag will generate a rotating force at the same time. The crushed slag and some impurities that are not completely filtered and crushed will fall to the bottom of the batching box through several leak holes under the centrifugal action of the conical crushing barrel;

[0019] S5: During the centrifugal process of the conical crushing barrel, some smaller and lighter impurities and slag will be thrown onto the inner wall of the conical crushing barrel. During the descending process of the hollow conical extrusion block, several cylinders and several limit springs will be driven to descend. The limit spring will drive the limit round rod to descend, and the limit round rod will drive the limit arc plate to descend. The limit arc plate will push down the slag and impurities thrown onto the inner wall of the conical crushing barrel. Since the inner wall of the conical crushing barrel is an arc-shaped inclined surface, under the action of the conical crushing barrel, the limit arc plate will move toward the direction close to the reciprocating screw. At this time, the limit spring will shrink. Under the elastic force of the limit spring, the limit arc plate will descend close to the conical crushing barrel. Before the hollow conical extrusion block presses the ore, the limit arc plate will push the impurities and slag on the inner wall of the conical crushing barrel to the top inner wall of the conical crushing barrel to ensure that the impurities and slag can be crushed by the hollow conical extrusion block.

[0020] The present invention has the following beneficial effects:

[0021] (1) The present invention discloses a batching device for blast furnace slag silicate cement. The prepared slag is poured into a feed hopper. The slag enters the conical barrel in the batching box along with the feed hopper. Then the drive motor is started. The drive motor drives the reciprocating screw to rotate. The reciprocating screw drives the inclined plate and the conical barrel to rotate. Since some slag is heavier, the centrifugal force generated by the conical barrel during rotation has no obvious effect on the heavier slag. The inclined plate will throw out the slag that falls on the conical barrel during rotation. Under the centrifugal force of the rotation of the conical barrel, the heavier ore will be thrown out by the inclined plate and hit some The strip plate will generate a reaction force on the slag, causing the slag to break. The broken slag will move upward along the inclined surface of the conical cylinder under the centrifugal force of the conical cylinder and the inclined plate. The broken slag will leave the conical cylinder through the gap between the support rods. The larger slag will be retained in the conical cylinder by several support rods after hitting the support rods to continue to be broken, ensuring that the slag is broken into smaller pieces in the process, which is convenient for the subsequent crushing of the slag. In the process again, the impurities cannot be completely removed, so a small amount of impurities will fall into the conical crushing cylinder together with the slag;

[0022] (2) The present invention provides a batching equipment for blast furnace slag silicate cement. The inclined plate and the conical cylinder will discharge impurities from the conical cylinder through a plurality of impurity removal holes during the rotation process. Impurities on the inner wall of the conical cylinder will be discharged through the impurity removal holes on the inner wall of the bottom of the conical cylinder. Impurities rotating along the inclined surface of the conical cylinder will be discharged from the impurity removal holes on the inner wall of the conical cylinder. The discharged impurities will fall into the rectangular collecting box, and then will be discharged out of the batching box along with the two rectangular collecting boxes. Some of the slag leaving the conical cylinder will fall back to the top of the rectangular impurity discharge pipe. During the rotation of the conical cylinder, the two fixed L-shaped plates will be driven to rotate. The fixed L-shaped plates will drive the triangular annular plates to rotate. The triangular annular plates will drive the rectangular boxes to rotate. The rectangular boxes will drive the cleaning springs to rotate. The cleaning springs will drive the triangular plates to rotate. During the rotation of the triangular plates, the triangular plates will contact the rectangular impurity discharge pipe and produce an impact. The vibration generated by the impact will vibrate the impurities in the rectangular impurity discharge pipe. The vibration will improve the effect of impurities being discharged from the rectangular impurity discharge pipe, thereby preventing impurities from clogging the rectangular impurity discharge pipe and affecting the impurity removal effect of the device.

[0023] (3) The present invention provides a batching device for blast furnace slag silicate cement. After the triangular plate contacts the rectangular impurity discharge pipe, the triangular plate will slide upward under the action of its inclined surface. The rising of the triangular plate will cause the cleaning spring to be compressed and deformed. As the triangular plate rotates continuously, the bottom of the triangular plate will contact the top of the rectangular impurity discharge pipe. In the process of passing through the top of the rectangular impurity discharge pipe, the triangular plate will drive the slag on the top of the rectangular impurity discharge pipe to leave the top of the rectangular impurity discharge pipe. After the triangular plate leaves the rectangular impurity discharge pipe, the slag will fall onto the conical crushing cylinder under the action of gravity. In the process of the triangular plate repeatedly colliding and passing through the rectangular impurity discharge pipe, the triangular plate will continuously vibrate. After the triangular plate takes away the slag on the top of the rectangular impurity discharge pipe, the slag that is not taken away by the inclined surface of the rectangular impurity discharge pipe will slide to the inner wall of the batching box, providing conditions for the next round of cleaning of the triangular plate.

[0024] (4) The present invention provides a batching device for blast furnace slag silicate cement. During the continuous rotation of the reciprocating screw, the reciprocating screw drives the hollow conical extrusion block to move up and down reciprocatingly. The reciprocating screw also drives the conical crushing barrel to rotate. During the descent of the hollow conical extrusion block, the block contacts and crushes the slag and a small amount of impurities that fall on the conical crushing barrel. Under the pressure of the hollow conical extrusion block, the slag will become stationary. Under the action of the rotation of the conical crushing barrel, the slag will generate a rotating force at the same time. Under the action of rotation and pressure, the effect of crushing the slag and impurities will be improved. The crushed slag and some impurities that are not completely filtered and crushed will fall to the bottom of the batching box through a number of leaks under the centrifugal action of the conical crushing barrel. After the impurities and slag are crushed, the particle size of the impurities becomes smaller and the distribution becomes more uniform, thereby reducing the negative impact on the strength and stability of cement.

[0025] (5) The batching equipment of blast furnace slag silicate cement of the present invention can throw some smaller and lighter impurities and slag onto the inner wall of the conical crushing cylinder during the centrifugal process of the conical crushing cylinder, and can drive a plurality of cylinders and a plurality of limit springs to descend during the descending process of the hollow conical extrusion block, and the limit springs can drive the limit round rods to descend, and the limit round rods can drive the limit arc plate to descend, and the limit arc plate can push down the slag and impurities thrown onto the inner wall of the conical crushing cylinder. It is an arc-shaped inclined surface. Under the action of the conical crushing barrel, the limit arc plate will move toward the direction close to the reciprocating screw. At this time, the limit spring will shrink. Under the elastic force of the limit spring, the limit arc plate will descend close to the conical crushing barrel. Before the hollow conical extrusion block presses the ore, the limit arc plate will push the impurities and slag on the inner wall of the conical crushing barrel to the top inner wall of the conical crushing barrel, thereby improving the crushing effect of the hollow conical extrusion block and ensuring that the impurities and slag can be crushed by the hollow conical extrusion block.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] like Figure 1-8 The batching equipment of blast furnace slag silicate cement is shown, and the method steps are as follows:

[0054] S1: When in use, the prepared slag is poured into the feed hopper 203, and the slag will enter the conical barrel 103 in the batching box 1 along with the feed hopper 203, and then the drive motor 202 is started, and the drive motor 202 drives the reciprocating screw 106 to rotate, and the reciprocating screw 106 drives the inclined plate 107 and the conical barrel 103 to rotate.

Some of the slag leaving the conical cylinder 103 It falls back to the top of the rectangular impurity discharge pipe 304. During the rotation of the conical cylinder 103, the two fixed L-shaped plates 401 are driven to rotate, the fixed L-shaped plates 401 drive the triangular annular plates 402 to rotate, the triangular annular plates 402 drive the rectangular box 403 to rotate, the rectangular box 403 drives the cleaning spring 404 to rotate, the cleaning spring 404 drives the triangular plate 405 to rotate, and during the rotation of the triangular plate 405, it will contact the rectangular impurity discharge pipe 304 and produce an impact, and the vibration generated by the impact will vibrate the impurities in the rectangular impurity discharge pipe 304;

[0056] S3: After the triangular plate 405 contacts the rectangular debris discharge pipe 304, the triangular plate 405 will slide upward under the action of its inclined surface. The rise of the triangular plate 405 will compress and deform the cleaning spring 404. As the triangular plate 405 rotates continuously, the bottom of the triangular plate 405 will contact the top of the rectangular debris discharge pipe 304. When the triangular plate 405 passes through the top of the rectangular debris discharge pipe 304, it will drive the slag on the top of the rectangular debris discharge pipe 304 to leave the top of the rectangular debris discharge pipe 304. After the angle plate 405 leaves the rectangular impurity discharge pipe 304, the slag will fall onto the conical crushing cylinder 501 under the action of gravity. In the process of the angle plate 405 repeatedly hitting and passing through the rectangular impurity discharge pipe 304, the angle plate 405 will continuously vibrate. After the angle plate 405 takes away the slag on the top of the rectangular impurity discharge pipe 304, the slag that is not taken away will slide to the inner wall of the batching box 1 under the action of the inclined surface of the rectangular impurity discharge pipe 304, providing conditions for the next round of cleaning of the angle plate 405.

[0057] S4: During the continuous rotation of the reciprocating screw 106, the reciprocating screw 106 will drive the hollow conical extrusion block 503 to reciprocate up and down, and the reciprocating screw 106 will also drive the conical crushing barrel 501 to rotate. During the descent of the hollow conical extrusion block 503, it will contact and crush the slag and a small amount of impurities that fall on the conical crushing barrel 501. The slag will be stationary under the pressure of the hollow conical extrusion block 503, and the slag will generate a rotating force under the action of the rotation of the conical crushing barrel 501. The crushed slag and some impurities that are not completely filtered and crushed will fall onto the bottom inner wall of the batching box 1 through a plurality of leakage holes 502 under the centrifugal action of the conical crushing barrel 501;

[0058] S5: During the centrifugal process of the conical crushing cylinder 501, some smaller and lighter impurities and slag will be thrown onto the inner wall of the conical crushing cylinder 501. During the descending process of the hollow conical extrusion block 503, several cylinders 601 and several limit springs 602 will be driven to descend. The limit springs 602 will drive the limit round rods 603 to descend. The limit round rods 603 will drive the limit arc plate 604 to descend. The limit arc plate 604 will push down the slag and impurities thrown onto the inner wall of the conical crushing cylinder 501. Since the inner wall of the conical crushing cylinder 501 is an arc shaped inclined surface, under the action of the conical crushing barrel 501, the limit arc plate 604 will move towards the direction close to the reciprocating screw 106, at this time, the limit spring 602 will shrink, and under the elastic force of the limit spring 602, the limit arc plate 604 will descend close to the conical crushing barrel 501, and before the hollow conical extrusion block 503 presses the ore, the limit arc plate 604 will push the impurities and slag on the inner wall of the conical crushing barrel 501 to the top inner wall of the conical crushing barrel 501, ensuring that the impurities and slag can be crushed by the hollow conical extrusion block 503.

Since some slag is heavier, the centrifugal force generated by the conical barrel (103) during rotation has no obvious effect on the heavier slag. The inclined plate (107) will throw out the slag that falls on the conical barrel (103) during rotation, and the slag will be discharged by the inclined plate (107) during the coordination. Under the centrifugal force of the rotating conical cylinder (103), heavier ore will be thrown out by the inclined plate (107) and hit a plurality of strip plates (105), and the strip plates (105) will generate a reaction force on the slag, causing the slag to be crushed. The crushed slag will move upward along the inclined surface of the conical cylinder (103) under the centrifugal force of the conical cylinder (103) and the inclined plate (107), and the crushed slag will leave the conical cylinder (103) through the gap between the support rods (301). After hitting the support rods (301), the larger slag will be retained in the conical cylinder (103) by the plurality of support rods (301) and continue to be crushed; S2: During the rotation process, the inclined plate (107) and the conical cylinder (103) will discharge impurities from the conical cylinder (103) through a plurality of impurity removal holes (104).

Impurities rotating along the inclined surface of the conical cylinder (103) will be discharged from the impurity removal holes (104) on the inner wall of the conical cylinder (103). The discharged impurities will fall into the rectangular collection box (303) and then be discharged from the batching box (1) along with the two rectangular collection boxes (303). Some of the slag leaving the conical cylinder (103) When the conical cylinder (103) falls back to the top of the rectangular impurity discharge pipe (304), the two fixed L-shaped plates (401) are driven to rotate during the rotation of the conical cylinder (103), the fixed L-shaped plates (401) drive the triangular annular plates (402) to rotate, the triangular annular plates (402) drive the rectangular box (403) to rotate, the rectangular box (403) drives the cleaning spring (404) to rotate, the cleaning spring (404) drives the triangular plate (405) to rotate, and during the rotation of the triangular plate (405), the triangular plate (405) contacts the rectangular impurity discharge pipe (304) and generates an impact, and the vibration generated by the impact vibrates the impurities in the rectangular impurity discharge pipe (304); S3: After the triangular plate (405) contacts the rectangular impurity discharge pipe (304), the triangular plate (405) will slide upwards under the action of its inclined surface. The rise of the triangular plate (405) will cause the cleaning spring (404) to be compressed and deformed.

After the triangular plate (405) takes away the slag on the top of the rectangular impurity discharge pipe (304), the slag that is not taken away will slide to the inner wall of the batching box (1) under the action of the inclined surface of the rectangular impurity discharge pipe (304), providing conditions for the next round of cleaning of the triangular plate (405); S4: During the continuous rotation of the reciprocating screw (106), the reciprocating screw (106) drives the hollow conical extrusion block (503) to move up and down reciprocatingly. At the same time, the reciprocating screw (106) also drives the conical crushing barrel (501) to rotate. During the descent of the hollow conical extrusion block (503), the slag and a small amount of impurities that fall on the conical crushing barrel (501) are contacted and crushed. Under the pressure of the hollow conical extrusion block (503), the slag will become stationary.

Under the action of the conical pulverizing cylinder (501), the limit arc plate (604) will move towards the direction close to the reciprocating screw (106). At this time, the limit spring (602) will shrink. Under the elastic force of the limit spring (602), the limit arc plate (604) will descend close to the conical pulverizing cylinder (501). Before the hollow conical extrusion block (503) presses the ore, the limit arc plate (604) will push the impurities and slag on the inner wall of the conical pulverizing cylinder (501) to the top inner wall of the conical pulverizing cylinder (501), ensuring that the impurities and slag can be crushed by the hollow conical extrusion block (503).
