Description

Technical Field

[0001] This utility model relates to the field of grouting pump technology, and in particular to a high-speed vortex grouting mixing and conveying integrated equipment. Background Technology

[0002] In many fields such as construction engineering, foundation reinforcement, geological disaster management, and mine backfilling, the preparation (mixing) and transportation (grouting) of grout are two crucial and closely linked processes. Traditional methods for handling cement grout, cement mortar, and other grouts typically employ a combination of separate equipment: one mixer (such as a low-speed horizontal mixer or a regular vertical mixer) is used to prepare the grout, and then the prepared grout is transferred to another transportation device (such as a screw grouting pump, centrifugal slurry pump, or plunger pump) for transportation and injection. To improve efficiency and facilitate handling, grouting equipment that integrates mixing and transportation has emerged.

[0003] The mortar accumulated in the discharge pipe of existing integrated mixing and conveying grouting equipment is inconvenient to clean and is prone to solidification, leading to blockage.

[0004] A screw-type intelligent grouting pump with high-speed stirring is disclosed in Chinese patent document CN219672862U. This pump includes a stirring drum, a cement feeding port located on the upper left side of the stirring drum, an electrical control box installed on the lower left side of the stirring drum, a stirring transmission rod installed inside the stirring drum, a transmission rod pulley installed above the stirring transmission rod, a discharge pipe installed below the stirring drum, and an electric valve installed inside the discharge pipe; a stirring motor is also included. The aforementioned screw-type intelligent grouting pump with high-speed mixing, mounted on the right side of the mixing drum, solves the inconvenience of using a screw-type intelligent grouting pump and a high-speed slurry mixer simultaneously by setting a high-speed mixing structure on the screw-type intelligent grouting pump, consisting of a mixing motor, motor pulley, transmission belt, transmission rod pulley, mixing transmission rod, cement feeding port, and mixing drum. This improves the working efficiency of the screw-type intelligent grouting pump. However, the mortar accumulated in the discharge pipe of the screw-type intelligent grouting pump with high-speed mixing is inconvenient to clean and is prone to solidification, leading to blockage.

[0005] To address the shortcomings of the existing technology, providing a high-speed vortex grouting mixing and conveying integrated device is a problem worthy of research. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of mortar accumulating in the discharge pipe being inconvenient to clean and easily solidifying and causing blockage. It provides a high-speed vortex grouting mixing and conveying integrated equipment, which achieves the technical effect of conveniently cleaning mortar accumulated in the discharge pipe.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A high-speed eddy current grouting mixing and conveying integrated equipment includes a mortar mixing chamber, a spiral booster chamber disposed below the mortar mixing chamber, and a grouting discharge pipe disposed at the output end of the spiral booster chamber. It also includes a spiral shaft rotatably connected to the spiral booster chamber, a spiral plate fixedly connected to the spiral shaft, and a dredging mechanism disposed within the spiral shaft.

[0009] The unblocking mechanism includes a through hole at the center of the spiral shaft, an unblocking rod inside the through hole, a limiting piston at one end of the unblocking rod, and a threaded hole at the other end of the unblocking rod.

[0010] The length and inner diameter of the through hole are equal to the length and diameter of the unblocking rod, and the diameter of the limiting piston is equal to the inner diameter of the grouting outlet pipe. This pushes out the mortar accumulated in the grouting outlet pipe, preventing the mortar from accumulating and solidifying in the grouting outlet pipe and causing blockage. After unblocking, the unblocking rod can be retracted into the through hole, thereby achieving rapid unblocking of the grouting outlet pipe.

[0011] The threaded hole is internally connected to a limiting bolt. The end width of the limiting bolt is greater than the diameter of the dredging rod, which fixes the dredging rod in the through hole and seals it to prevent it from entering the through hole during mortar transportation.

[0012] One end of the spiral shaft extends out of the spiral pressurization chamber, and a first gear is fixedly connected to the extended end of the spiral shaft. A first motor is fixedly connected to one side of the spiral pressurization chamber, and a second gear is fixedly connected to the output end of the first motor. The first gear and the second gear mesh with each other. By setting the meshing first gear and the second gear on the outside of the spiral pressurization chamber, the first motor can drive the spiral shaft and the spiral plate to rotate under gear transmission, thereby squeezing the mortar entering the spiral pressurization chamber into the grouting discharge pipe, thus completing the mortar transportation.

[0013] The width of the spiral plate is adapted to the inner diameter of the spiral booster chamber, and the bottom of the mortar mixing chamber is connected to one end of the top of the spiral booster chamber.

[0014] The mortar mixing chamber is internally connected to a stirring shaft, and a second motor is fixedly connected to the top center of the mortar mixing chamber. The output end of the second motor is fixedly connected to the rotating shaft of the stirring shaft, so that the stirring shaft continuously performs high-speed vortex stirring on the mortar entering the mortar mixing chamber, making the mortar more uniform and avoiding the situation where the mortar solidifies rapidly in a static state, affecting the conveying effect.

[0015] A feed inlet is provided on one side of the top of the mortar mixing chamber. The feed inlet is hemispherical and one side of the feed inlet is connected to the mortar mixing chamber.

[0016] Positive and beneficial effects:

[0017] 1. When residual mortar accumulates in the grouting outlet pipe and is inconvenient to clean, a threaded rod is installed at the end of the unblocking rod through a threaded hole. The installed threaded rod then pushes the unblocking rod and the limiting piston into the grouting outlet pipe, thereby pushing out the mortar accumulated in the grouting outlet pipe and preventing the mortar from accumulating and solidifying in the grouting outlet pipe, which could lead to blockage.

[0018] 2. This high-speed vortex grouting mixing and conveying integrated equipment installs a limiting bolt into the threaded hole, so that the end of the limiting bolt interacts with the spiral shaft to limit the unblocking rod. The limiting piston limits the other end of the unblocking rod, thereby fixing the unblocking rod in the through hole and sealing the unblocking rod to prevent it from entering the through hole during mortar conveying.

[0019] 3. This high-speed vortex grouting mixing and conveying integrated equipment uses a second motor-driven mixing shaft inside the mortar mixing chamber to continuously and rapidly vortex mix the mortar entering the mortar mixing chamber, making the mortar more uniform and avoiding the situation where the mortar solidifies rapidly in a static state, which would affect the conveying effect.

Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0029] like Figures 1 to 7 As shown, a high-speed eddy current grouting mixing and conveying integrated equipment includes a mortar mixing chamber 1, a spiral booster chamber 2 disposed below the mortar mixing chamber 1, and a grouting discharge pipe 3 disposed at the output end of the spiral booster chamber 2. It also includes a spiral shaft 4 rotatably connected to the spiral booster chamber 2, a spiral plate 5 fixedly connected to the spiral shaft 4, and a dredging mechanism 6 disposed in the spiral shaft 4.

[0030] like Figures 4 to 7 As shown, the unblocking mechanism 6 includes a through hole 601 opened at the center of the spiral shaft 4, an unblocking rod 602 disposed inside the through hole 601, a limiting piston 603 disposed at one end of the unblocking rod 602, and a threaded hole 604 opened at the other end of the unblocking rod 602.

[0031] like Figures 4 to 7 As shown, the length and inner diameter of the through hole 601 are equal to the length and diameter of the unblocking rod 602, and the diameter of the limiting piston 603 is equal to the inner diameter of the grouting outlet pipe 3. By setting the unblocking rod 602 with the limiting piston 603 at the center of the spiral shaft 4, the unblocking rod 602 retracts into the through hole 601 when the spiral booster chamber 2 is running normally, avoiding affecting the normal operation of the spiral shaft 4 and the spiral plate 5. When residual mortar accumulates in the grouting outlet pipe 3, the unblocking rod 602 is not allowed to move. For easy cleaning, a threaded rod is threaded into the end of the unblocking rod 602 through the threaded hole 604. The threaded rod then pushes the unblocking rod 602 and the limiting piston 603 into the grouting outlet pipe 3, thereby expelling the mortar accumulated in the grouting outlet pipe 3 and preventing the mortar from accumulating and solidifying in the grouting outlet pipe 3, which could cause blockage. After unblocking, the unblocking rod 602 is retracted into the through hole 601, thus achieving rapid unblocking of the grouting outlet pipe 3.

[0032] like Figures 4 to 7As shown, a limiting bolt 605 is connected to the internal thread of the threaded hole 604. The end width of the limiting bolt 605 is greater than the diameter of the unblocking rod 602. By setting the limiting bolt 605 at the end of the unblocking rod 602, when the unblocking rod 602 is retracted into the through hole 601, the limiting bolt 605 is installed into the threaded hole 604, so that the end of the limiting bolt 605 interacts with the spiral shaft 4 to limit the unblocking rod 602. The limiting piston 603 limits the other end of the unblocking rod 602, thereby fixing the unblocking rod 602 in the through hole 601 and sealing the unblocking rod 602 to prevent it from entering the through hole 601 during mortar transportation. Example 2

[0033] like Figures 2 to 3 As shown, one end of the spiral shaft 4 extends out of the spiral pressurizing chamber 2. A first gear 7 is fixedly connected to the extended end of the spiral shaft 4. A first motor 8 is fixedly connected to one side of the spiral pressurizing chamber 2. A second gear 9 is fixedly connected to the output end of the first motor 8. The first gear 7 and the second gear 9 mesh with each other. By setting the meshing first gear 7 and the second gear 9 on the outside of the spiral pressurizing chamber 2, the first motor 8 can drive the spiral shaft 4 and the spiral plate 5 to rotate under gear transmission, thereby squeezing the mortar entering the spiral pressurizing chamber 2 into the grouting discharge pipe 3, thus completing the mortar conveying.

[0034] like Figures 4 to 7 As shown, the width of the spiral plate 5 is adapted to the inner diameter of the spiral booster chamber 2, and the bottom of the mortar mixing chamber 1 is connected to the top of the spiral booster chamber 2. Example 3

[0035] like Figures 1 to 5 As shown, a stirring shaft 10 is rotatably connected inside the mortar mixing chamber 1. A second motor 11 is fixedly connected at the top center of the mortar mixing chamber 1. The output end of the second motor 11 is fixedly connected to the rotating shaft of the stirring shaft 10. By setting the stirring shaft 10 driven by the second motor 11 inside the mortar mixing chamber 1, the stirring shaft 10 continuously performs high-speed vortex stirring on the mortar entering the mortar mixing chamber 1, making the mortar more uniform and avoiding the situation where the mortar solidifies rapidly in a static state, affecting the conveying effect.

[0036] like Figures 1 to 5 As shown, a feed inlet 12 is provided on one side of the top of the mortar mixing chamber 1. The feed inlet 12 is hemispherical and one side of the feed inlet 12 is connected to the mortar mixing chamber 1.

[0037] The working principle of this utility model is as follows:

[0038] S1. When the spiral booster chamber 2 is running normally, the unblocking rod 602 is retracted into the through hole 601 to avoid affecting the normal operation of the spiral shaft 4 and the spiral plate 5.

[0039] S2. When residual mortar accumulates in the grouting outlet pipe 3 and is inconvenient to clean, a threaded rod is installed at the end of the unblocking rod 602 through the threaded hole 604. The installed threaded rod pushes the unblocking rod 602 and the limiting piston 603 into the interior of the grouting outlet pipe 3, thereby pushing out the mortar accumulated in the grouting outlet pipe 3 and avoiding the situation where the mortar accumulates and solidifies in the grouting outlet pipe 3, causing blockage.

[0040] S3. After the unblocking is completed, simply retract the unblocking rod 602 into the through hole 601;

[0041] S4. Install the limiting bolt 605 into the threaded hole 604, so that the end of the limiting bolt 605 interacts with the spiral shaft 4 to limit the unblocking rod 602. The limiting piston 603 limits the other end of the unblocking rod 602, thereby fixing the unblocking rod 602 in the through hole 601 and sealing the unblocking rod 602 to prevent it from entering the through hole 601 during mortar transportation.

[0042] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
