Description

Technical Field

[0001] The invention belongs to the technical field of mixing equipment, and more specifically, relates to a mine grouting mixing equipment. Background Art

[0002] Mine water hazards are one of the major hidden dangers threatening coal mine safety and production, and are also a major factor restricting production activities and sustainable development in many mining areas. Currently, as mining depth increases, the amount of water inflow in mines continues to increase. Discontinuities such as joints and fissures in the broken rock mass act as water conduits, causing large amounts of water inflow within the coal rock mass, posing a serious threat to underground coal mine safety. To prevent the threat of water inrush from the pressurized aquifers in the coal seam floor, grouting has become an effective measure to prevent and control mine water hazards and ensure safe mining.

[0003] Conventional grouting materials often use slurries mainly composed of cement, clay, or a mixture of the two. In order to further improve the strength and anti-seepage effect of the clay slurry after injection, chemical modifiers are often added to the clay-based slurry to improve related properties. However, in the prior art, during the preparation of grouting materials, since the materials are mostly granular, stirring is required to ensure uniform mixing. However, with existing stirring equipment, new materials cannot be added after stirring is completed before the materials are emptied. New mixed materials must be prepared only after the materials are emptied, which is inefficient and not conducive to improving grouting efficiency. Summary of the Invention

[0032] The mine grouting and mixing equipment provided by the present invention is now described.

[0033] Please also refer to Figure 1 and Figure 2 The mine grouting mixing equipment includes a mixing barrel 1, a partition 2, a stirring device 5, two feed hoppers 3 and two discharge ports, wherein the mixing barrel 1 is hollow; the partition 2 is arranged in the mixing barrel 1, and the partition 2 divides the internal space of the mixing barrel 1 into an upper stirring chamber 101 and a lower stirring chamber 102; the stirring device 5 is arranged in the mixing barrel 1, and the stirring device 5 can stir the materials in the upper stirring chamber 101 and the lower stirring chamber 102; the two feed hoppers 3 are both arranged on the side wall of the mixing barrel 1, one of the feed hoppers 3 is connected to the upper stirring chamber 101, and the other feed hopper 3 is connected to the lower stirring chamber 102; one of the discharge ports is arranged on the side wall of the upper stirring chamber 101, and the other discharge port is arranged on the side wall of the lower stirring chamber 102.

[0034] The beneficial effect of the mine grouting and mixing equipment provided in this embodiment is as follows: compared with the prior art, the mine grouting and mixing equipment provided in this embodiment divides the space in the mixing barrel 1 into an upper stirring chamber 101 and a lower stirring chamber 102 by adding a partition 2 in the mixing barrel 1, and correspondingly, feed ports and discharge ports are provided in the upper stirring chamber 101 and the lower stirring chamber 102, so that when the upper stirring chamber 101 discharges materials, the lower stirring chamber 102 can continue to stir and make new mixed materials, and when the lower stirring chamber 102 discharges materials, the upper stirring chamber 101 can continue to make new mixed materials. During the grouting process, the mine grouting and mixing equipment of the present invention can prepare new mixed materials without stopping, thereby greatly improving the grouting efficiency.

[0035] Based on the above design concept, the stirring device 5 of the present invention includes a first stirring mechanism 501, a second stirring mechanism 502, and a driving mechanism. The driving mechanism is connected to the first stirring mechanism 501 and the second stirring mechanism 502, respectively. The first stirring mechanism 501 can stir the material in the stirring barrel 1 along the circumference of the stirring barrel, and the second stirring mechanism 502 can stir the material in the stirring barrel 1 along the axial direction of the stirring barrel. Because the material used for grouting contains granular material, which is prone to sedimentation in the stirring barrel 1, the provision of the second stirring mechanism 502 can lift the sedimented material to a higher position for mixing. The cooperation between the first stirring mechanism 501 and the second stirring mechanism 502 effectively improves the stirring efficiency of the material and can make the material mixed more evenly.

[0036] Specifically in this embodiment, the first stirring mechanism 501 includes a plurality of pivot rods 504, which are arranged through the partition 2. A plurality of stirring blades 505 are evenly arranged on the pivot rods 504. The driving mechanism drives the pivot rods 504 to rotate. The pivot rods 504 achieve mixing of the materials during the rotation process.

[0037] like Figure 4 and Figure 5 As shown, the second stirring mechanism 502 includes a fixed cylinder 506 and a spiral stirring rod 507. The fixed cylinder 506 is fixed in the stirring barrel 1, and the bottom end of the fixed cylinder 506 abuts against the bottom end of the stirring barrel 1. The top of the fixed cylinder 506 is arranged near the top of the upper stirring chamber 101. Two feed ports 508 are provided on the fixed cylinder 506, one of which is arranged near the bottom end of the lower stirring chamber 102, and the other feed port 508 is arranged near the bottom end of the upper stirring chamber 101. Two discharge ports 509 are provided on the fixed cylinder 506, one of which is arranged near the top end of the lower stirring chamber 102, and the other discharge port 509 is arranged near the top end of the upper stirring chamber 101. The top end of the spiral stirring rod 507 is connected to the driving mechanism. The fixed cylinder 506 and the spiral stirring rod 507 cooperate to lift the material at the bottom of the lower stirring chamber 102 to the top of the lower stirring chamber 102 and discharge it, and lift the material in the upper stirring chamber 101 to the top of the upper stirring chamber 101 and discharge it, so that the materials in the lower stirring chamber 102 and the upper stirring chamber 101 are mixed more evenly.

[0038] As a preferred solution, the drive mechanism includes a first motor, a plurality of first gears 510 and a second gear 511. A bracket 512 is provided at the top of the mixing barrel 1. The first motor is mounted on the bracket 512. The top end of the spiral stirring rod 507 is connected to the first motor. The second gear is mounted on the spiral stirring rod 507. The first gear 510 corresponds to the pivot rod 504 one-to-one. The first gear 510 is mounted on the corresponding stirring rod. The second gear 511 meshes with the first gear 510, and the diameter of the second gear 511 is larger than that of the first gear 510. The coordination of the first gear 510 and the second gear 511 enables a single first drive motor 503 to simultaneously drive the first stirring mechanism 501 and the second stirring mechanism 502 for stirring. Moreover, because the diameter of the second gear 511 is larger than that of the first gear 510, the pivot rod 504 rotates faster, resulting in higher stirring efficiency.

[0039] like Figure 2 and Figure 4As shown, a discharge pipe 4 is connected to the discharge port. Part of the discharge pipe 4 is located outside the mixing barrel 1, and the other part of the discharge pipe 4 is located inside the mixing barrel 1. One end of the discharge pipe 4 located inside the mixing barrel 1 abuts against the fixed barrel 506. The fixed barrel 506 is rotatably arranged. Along the circumference of the fixed barrel 506, two discharge ports 509 are staggered. The fixed barrel 506 can connect the discharge port 509 in the lower mixing chamber 102 with the discharge pipe 4 or connect the discharge port 509 in the upper mixing chamber 101 with the discharge pipe 4 due to rotation. When the discharge port 509 is connected to the discharge pipe 4, the material in the mixing barrel 1 is discharged; when the discharge port 509 is disconnected from the discharge pipe 4, the material is stirred. Furthermore, since the discharge port 509 is staggered, the lower stirring chamber 102 can discharge materials when the upper stirring chamber 101 is stirring; or the upper stirring chamber 101 can discharge materials when the lower stirring chamber 102 is stirring.

[0040] A drive rod 513 is provided at the bottom of the fixed cylinder 506. The drive rod 513 extends downwardly below the mixing drum 1. A second drive motor 514 is provided below the mixing drum 1. The bottom end of the drive rod 513 is connected to the power output of the second drive motor 514. A locking mechanism is provided at the bottom of the mixing drum 1. When the locking mechanism is locked, the drive rod 513 is fixed relative to the mixing drum 1; when the locking mechanism is unlocked, the drive rod 513 can rotate relative to the mixing drum 1. The provision of a third drive motor 518, which will be described below, facilitates switching the unlocking mechanism between locking and unlocking.

[0041] like Figure 6 As shown, the locking mechanism includes a fixed block 515 and two clamping plates 516. The clamping plates 516 are slidably mounted on the bottom of the mixing drum 1. Specifically, a chute is provided at the bottom of the mixing drum 1, and the cross-section of the chute is convex. A slider is provided at the bottom of the clamping plates 516, and the cross-section of the slider is also convex. The slider is inserted into the chute.

[0042] A fixed half groove with a rectangular cross-section is provided on the splint 516. When the two splints 516 abut against each other, the two fixed half grooves are buckled together to form a fixed groove 517. The cross-section of the fixed groove 517 is square. The cross-section of the fixing block 515 is square, and the fixing block 515 is adapted to the fixed groove 517. The fixing block 515 is provided on the driving rod 513. When the locking mechanism is locked, the two splints 516 abut against each other due to sliding, and the fixing block 515 is inserted into the fixing groove 517; when the locking mechanism is unlocked, the two splints 516 slide away from each other.

[0043] To facilitate the sliding of the clamping plates 516, a third drive motor 518 is provided at the bottom of the mixing drum 1. Screws 519 are provided at both ends of the third drive motor 518. The clamping plates 516 are provided with escape grooves. When the two clamping plates 516 abut, the third drive motor 518 is located in the escape grooves. The clamping plates 516 are provided with drive blocks 520, each with a drive hole. Screws 519 correspond one-to-one with the clamping plates 516 and are screwed into the drive holes of the corresponding clamping plates 516. When the third drive motor drives the screws 519 to rotate, the clamping plates 516 slide along the slide grooves.

[0044] In addition, two mounting blocks 521 are provided at the bottom of the mixing barrel 1, and the mounting blocks 521 correspond one-to-one to the screw 519. Relative to the end connected to the third drive motor, the other end of the screw 519 is rotatably set on the mounting block 521. A contact switch 522 is provided on one of the mounting blocks 521. When the drive block 520 abuts against the contact switch, the second drive motor 514 is turned on, driving the fixed cylinder 506 to rotate a preset angle, releasing the connection between the discharge port 509 in the lower mixing chamber 102 and the discharge pipe 4, so that the discharge pipe in the upper mixing chamber 101 is connected to the discharge pipe 4, or releasing the connection between the discharge port 509 in the upper mixing chamber 101 and the discharge pipe 4, so that the discharge pipe in the lower mixing chamber 102 is connected to the discharge pipe 4.

[0045] like Figure 3 As shown, two baffles 103 are provided in the mixing barrel 1, one of which is located in the upper mixing chamber 101 and the other in the lower mixing chamber 102. A hinge 104 is provided between the top of the baffle 103 and the inner wall of the mixing barrel 1. The baffle 103 can be flipped around the hinge 104. When in its natural state, the baffle 103 blocks the feed hopper 3. The provision of the sealing plate prevents the material from splashing out of the feed hopper 3 during mixing.

[0046] Finally, a material collection trough is provided on the partition 2 and the bottom plate of the mixing barrel 1. The material collection trough is funnel-shaped, which can facilitate the sediment to be lifted to a high place for stirring by the second stirring mechanism 502 during stirring, and can facilitate the mixed materials to gather at the feed port 508 of the second stirring mechanism 502 for discharge during discharge.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
