DETAILED DESCRIPTION

[0028] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0030] Reference Figure 1-7 The present embodiment provides an engineering mud high-efficiency mixer, which includes a feed box 2, a mixing box 8 and a discharge box 28. The top and bottom ends of the mixing box 8 are respectively provided with a feed port and a discharge port. The feed box 2 is located at the top of the mixing box 8 and is connected to the feed port through a feed pipe 6 for feeding into the mixing box 8; the discharge box 28 is located at the bottom of the mixing box 8 and is used to output the slurry stirred by the mixing box 8; the inner side of the mixing box 8 is provided with a first partition cylinder 9 and a second partition cylinder 10 distributed coaxially, and the feed port is located at the first partition cylinder 9. The discharge port is located on the inner side of the second partition cylinder 10; the top end of the first partition cylinder 9 is closed, the bottom end is open and has a certain interval with the inner bottom surface of the mixing box 8, the second partition cylinder 10 is located in the first partition cylinder 9, the top end is open and has a certain interval with the inner top surface of the first partition cylinder 9, the bottom of the second partition cylinder 10 is fixed to the inner bottom surface of the mixing box 8, the first partition cylinder 9 and the second partition cylinder 10 separate an S-shaped feeding channel between the feed port and the discharge port, and a plurality of rotatable mixing blades are provided in the feeding channel.

[0031] By adopting the above technical scheme, an S-shaped feeding channel is separated in a mixing box 8 of a certain volume to extend the residence time of the slurry in the mixing box 8. The mixing blades in the S-shaped feeding channel are used to continuously stir the slurry to improve the mixing degree of the slurry. The slurry can be continuously discharged through the discharge box 28 without repeatedly opening and closing the discharge valve. The operation is simple and efficient.

[0032] During implementation, the number of feed boxes 2 can be determined according to the number of raw material types in the engineering mud. Each raw material can correspond to one feed box 2, or the solid raw material and liquid raw material can correspond to one feed box 2 respectively. The latter can reduce the total pressure of the feed box 2 on the mixing box 8.

[0033] Reference Figure 3A feed hopper 1 is provided on the top of the feed box 2 to facilitate pouring; a feed motor 3, feed blades 4 and a feed shaft 5 are arranged inside the feed box 2. The feed blades 4 are distributed on the feed shaft 5 and are driven to rotate by the feed motor 3. When the compounded solid raw materials are poured into the feed box 2, the feed motor 3 can be used to drive the feed blades 4 to rotate, so as to preliminarily mix the components in the solid raw materials to improve the subsequent mixing efficiency and mixing effect.

[0034] During implementation, the feed shaft 5 can be vertically arranged, and multiple rows of feed blades 4 are distributed along the axial direction of the feed shaft 5. Each row of feed blades 4 has several feed blades distributed along the circumference of the feed shaft 5. The feed blades 4 are provided with through holes that can pass through the solid raw materials, thereby improving the mixing efficiency of the components in the solid raw materials.

[0035] In addition, a feed valve 7 can be arranged on the feed pipe 6, and the feed valve 7 can be used to adjust the opening of the feed pipe 6, thereby controlling the feeding speed of the solid raw materials and the liquid raw materials, so as to adjust the concentration of the slurry and meet different construction requirements. The above-mentioned method of adjusting the concentration of the slurry by adjusting the feeding speed of the feed valve 7 means that before the formal construction, the feed valve 7 is pre-adjusted to change the opening of the feed pipe 6 so that the concentration of the slurry output by the discharge box 28 meets the requirements of this construction, rather than the complicated operation of repeatedly adjusting the feed valve 7 during a construction process. Since the engineering slurry needs to be continuously supplied during the construction process, the efficiency of feeding the solid raw materials and liquid raw materials with appropriate proportions into the mixing box 8 in batches and then feeding the next batch of materials after they are all mixed and output is too low, but the feed valve 7 is provided to realize continuous feeding according to the ratio and continuous output of the engineering slurry that meets the requirements, and its efficiency is greatly improved.

[0036] Reference Figure 4-7A first mixing motor 11 and a second mixing motor 12 are provided in the mixing box 8. The first mixing motor 11 is located at the top of the mixing box 8, and its output shaft is vertical and connected to the first mixing shaft 13. The first mixing shaft 13 passes through the top of the first partition cylinder 9 and extends into the inner side of the second partition cylinder 10. The first partition cylinder 9 is fixedly connected to the first mixing shaft 13 and can rotate with the first mixing shaft 13; the second mixing motor 12 is located at the bottom of the mixing box 8, and its output shaft is vertical and connected to the second mixing shaft 14. The second mixing shaft 14 is located inside the first partition cylinder 9 and outside the second partition cylinder 10; the mixing blades include a first mixing blade 15, a second mixing blade 16 and a third mixing blade 17. The first mixing blade 15 is fixedly arranged on the first partition cylinder 9 On the outer wall, the second mixing blade 16 is fixedly arranged on the second mixing shaft 14, and the third mixing blade 17 is located in the second partition cylinder 10 and fixedly connected to the first mixing shaft 13, that is: when the first mixing motor 11 drives the first mixing shaft 13 to rotate, the first mixing shaft 13 drives the first partition cylinder 9 and the first mixing blade 15 on the first partition cylinder 9 to rotate, and the first mixing shaft 13 drives the third mixing blade 17 to rotate. When the second mixing motor 12 drives the second mixing shaft 14 to rotate, the second mixing shaft 14 drives the second mixing blade 16 to rotate. The first mixing blade 15, the second mixing blade 16 and the third mixing blade 17 continuously stir the slurry in the S-shaped feeding channel, which can improve the stirring uniformity of the slurry.

[0037] Due to the continuous feeding of raw materials, the slurry is squeezed by the newly fed raw materials, and enters the channel between the first partition cylinder 9 and the second partition cylinder 10 from the outside of the first partition cylinder 9, and then is squeezed into the second partition cylinder 10 from the top of the second partition cylinder 10. The slurry can be smoothly transported in the S-shaped feeding channel, but the transportation efficiency is too low, which not only affects the construction efficiency, but also may cause slurry accumulation, block the motor, and affect the operation of the equipment. Therefore, in this embodiment, a spiral feeding blade 18 is provided on the second mixing shaft 14, and the spiral feeding blade 18 is used to feed the slurry under the first partition cylinder 9 to the second partition cylinder 10, speed up the feeding efficiency, and is not easy to be blocked; a spiral discharging blade 19 is provided on the first mixing shaft 13, and the spiral discharging blade 19 feeds the slurry in the second partition cylinder 10 to the discharge port, speeds up the feeding efficiency, and is not easy to be blocked.

[0038] In some feasible embodiments, the spiral transfer blade 18 is located below the second mixing blade 16, and the spiral discharge blade 19 is located below the third mixing blade 17. The cooperation between the second mixing blade 16 and the spiral transfer blade 18 can improve the transfer efficiency and mixing uniformity, and the cooperation between the third mixing blade 17 and the spiral discharge blade 19 can improve the transfer efficiency and mixing uniformity.

[0039] Similar to the feed blades 4, the first mixing blades 15 may be arranged in several rows on the outer wall of the first partition cylinder 9 along the axial direction thereof, and each row of first mixing blades 15 may have several first mixing blades 15 distributed along the circumferential direction of the first partition cylinder 9; the second mixing blades 16 may be arranged in several rows on the second mixing shaft 14 along the axial direction thereof, and each row of second mixing blades 16 may have several second mixing blades distributed along the circumferential direction of the second mixing shaft 14; the third mixing blades 17 may be arranged in several rows on the first mixing shaft 13 along the axial direction thereof, and each row of third mixing blades 17 may have several third mixing blades distributed along the circumferential direction of the first mixing shaft 13, so as to improve the uniformity of mixing.

[0040] In addition, in this embodiment, a scraper arm 20 is provided at the bottom of the first partition cylinder 9, and the scraper arm 20 is fixedly connected to the first partition cylinder 9, and a plurality of scraper arms 20 are distributed along the circumference of the first partition cylinder 9, and the inner bottom surface of the mixing box 8 abuts against the bottom surface of the scraper arm 20. When the first partition cylinder 9 rotates, the scraper arm 20 can be driven to rotate together, and the scraper arm 20 can scrape the inner bottom surface of the mixing box 8, thereby improving the discharge effect of the mud and facilitating the cleaning of the inside of the mixing box 8.

[0041] To facilitate the installation, disassembly and maintenance of the equipment, the scraper arm 20 can be set on the mounting ring 21, and the mounting ring 21 can be detachably arranged at the bottom of the first partition 9. To improve the material transfer efficiency, a material transfer hopper 22 can be set on the top of the second partition 10. The inner diameter of the material transfer hopper 22 gradually decreases from top to bottom. When the slurry is delivered to the material transfer hopper 22, it can flow downward along the side wall of the material transfer hopper 22 to ensure smooth material transfer.

[0042] In order to further improve the mixing uniformity of the slurry, in this embodiment, an annular support plate 23 is sleeved on the outside of the first partition 9, the inner wall of the mixing box 8 is fixedly connected to the outer wall of the annular support plate 23, the inner wall of the annular support plate 23 abuts against the outer wall of the first partition 9, the bottom surface of the first mixing blade 15 abuts against the top surface of the annular support plate 23, and a leakage hole 24 is provided on the annular support plate 23. The residence time of the slurry at the first mixing sheet is extended by the annular support plate 23, and the mixing uniformity is improved.

[0043] In addition, an hourglass-shaped tube 25 can be arranged above the first mixing blade 15. The hourglass-shaped tube 25 is fixed on the outer wall of the first partition tube 9, and its axis is tangent to the outer wall of the first partition tube 9. The hourglass-shaped tube 25 gradually expands in diameter from the middle to both ends, and its both ends are open. Rotating blades 26 are arranged on the inner side of the middle, and the rotating shaft of the rotating blades 26 is perpendicular to the axis of the hourglass-shaped tube 25. When the first mixing motor 11 drives the first partition tube 9 to rotate, the first mixing blade 15 and the hourglass-shaped tube 25 also rotate accordingly, and part of the slurry enters the hourglass-shaped tube 25. Since the flow rate of the slurry inside and outside the hourglass-shaped tube 25 is different, the flow rate of the slurry at different diameters in the hourglass-shaped tube 25 is also different. With the rotating blades 26 in the hourglass-shaped tube 25, the slurry is more fully stirred.

[0044] During implementation, the hourglass-shaped tube 25 can be composed of two conical tubes and a hollow tube, and the rotating blade 26 is rotatably set in the hollow tube. Since the diameters of the two ends of the hourglass-shaped tube 25 are relatively large, the hollow tube can be connected to the outer wall of the first partition tube 9 by setting a connecting rod 27; adopting the above technical scheme, the first mixing blade 15, the second mixing blade 16, the third mixing blade 17, and the hourglass-shaped tube 25 can be used to fully stir the slurry, and the spiral transfer blade 18 and the spiral discharging blade 19 can improve the circulation efficiency of the slurry in the mixing box 8, prevent blockage and improve the discharging efficiency.

[0045] Reference Figure 5 The top of the discharge box 28 is connected to the discharge port of the mixing box 8, and the other side of the discharge box 28 along the length direction is opened for discharging; a discharge auger 29 and a discharge motor 30 are provided in the discharge box 28, and the discharge auger 29 is driven by the discharge motor 30 to rotate to discharge the slurry and provide stirring force for the slurry during the slurry discharge process, which is not easy to precipitate and has a better conveying effect.

[0046] To facilitate the slurry transportation, support legs 31 can be provided at the bottom of the mixing box 8 to raise the mixing box 8 and the discharge box 28, and use the gravity of the slurry itself to improve the discharge smoothness and discharge speed. To improve stability, foot pads 32 can be provided at the bottom of the support legs 31. The area of ​​the foot pads 32 is larger than the cross-sectional area of ​​the support legs 31, which can increase the contact area with the ground and improve the support stability.

[0047] The method of using the present embodiment includes: starting the feed motor 3, and using the feed blade 4 to preliminarily stir the raw materials before the raw materials are sent to the mixing box 8; through the feed valve 7 with a pre-adjusted opening, the solid raw materials and the liquid raw materials are sent to the mixing box 8 in proportion, and the first mixing motor 11 and the second mixing motor 12 are started. Under the conflicting effects of the annular support plate 23 and the slurry's own gravity, the slurry slowly falls outside the first partition 9 and is stirred by the first mixing blade 15 and the hourglass-shaped tube 25. When the slurry falls to the bottom of the mixing box 8, it is stirred by the spiral conveying blade 18 and is transmitted upward to the second partition cylinder 10. During this period, the second mixing blade 16 also stirs the slurry transmitted upward to improve the mixing uniformity of the slurry. After the slurry enters the second partition cylinder 10, it falls in the second partition cylinder 10 due to its own gravity and the synergistic effect of the spiral discharging blades 19. During this period, the third mixing blade 17 also stirs the falling slurry to improve the mixing uniformity of the slurry. Finally, the slurry falls into the discharging box 28, and the discharging motor 30 is started, which drives the discharging auger 29 to rotate, and then the slurry is discharged.

[0048] Compared with the prior art, the beneficial effects of the present invention are as follows: an S-shaped feeding channel is separated in a mixing box 8 of a certain volume to extend the residence time of the slurry in the mixing box 8, and the mixing blades in the S-shaped feeding channel are used to continuously stir the slurry to improve the uniformity of the slurry, and the slurry can be continuously discharged through the discharge box 28 without repeatedly opening and closing the discharge valve, which is simple to operate and efficient.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0050] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
