Description

Technical Field

[0001] This invention relates to the field of slurry preparation technology, specifically to a pore-sealing material mixing device. Background Technology

[0002] In the process of coal mining, grouting and sealing is a key link to ensure the safety of underground operations. Its core function is to seal the fissures and channels of coal and rock strata around the borehole, effectively preventing gas outbursts, roof water hazards and harmful gas leaks, and creating a safe and stable working environment for the mining face.

[0003] As coal mining depths continue to increase and underground geological conditions become increasingly complex, the performance requirements for sealing grouts have significantly increased. Dual-liquid mixed grouting technology, which combines the advantages of controllable setting time, high strength of the rock mass, and good sealing performance, has gradually become the mainstream solution.

[0004] Two-component grouting typically relies on a dual-tank storage and mixing system to independently prepare each component before mixing and injecting it into the borehole according to the designed ratio. However, existing dual-tank systems mostly use tanks of the same volume, and to ensure tank strength, transparent materials are not suitable. Therefore, it is inconvenient to set precise graduations on the tanks for different mixing ratios. Operators cannot visually judge the amount of each component added by the liquid level, and additional measuring tools such as scales and flow meters are required for secondary measurement. In addition, since the amount of the two grouts needs to be dynamically adjusted according to the ratio, the tanks of the same volume cannot visually reflect the relative volume relationship between the two, making it difficult for operators to accurately control the actual addition ratio of each component, which in turn leads to problems such as abnormal grout setting time and insufficient strength of the grout. Summary of the Invention

[0005] The purpose of this invention is to provide a sealing material mixing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sealing material mixing device, comprising a base, at least two preparation barrels being provided on the top of the base, and a stirring structure for mixing slurry being provided on the top of the preparation barrels;

[0007] It also includes a feeding indicator structure, which is disposed between the two preparation barrels.

A secondary float is fixedly connected to the bottom of the secondary lower probe rod. The main lower probe rod and the secondary lower probe rod are respectively located in two adjacent preparation barrels.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1:

[0028] This invention discloses a sealing material mixing device, used to visually display the real-time timing of slurry addition into the two tanks during dual-tank pulping and mixing. Figure 1-5As shown, the system includes a base 1, with at least two preparation tanks 2 mounted on top of the base 1. The two preparation tanks 2 are identical in size, inner diameter, and volume, and are used to prepare two-component grouts for two-component injection, such as cement-water glass two-component grout or polyurethane chemical two-component grout. Each preparation tank 2 has a stirring structure on top for mixing the grout. The system also includes a feeding indicator structure positioned between the two preparation tanks 2. The feeding indicator structure includes a fixed rod 3 fixedly connected to the top of the base 1, with graduation lines on its surface. A sleeve 31 slides on the surface of the fixed rod 3, and a main lower probe rod 33 is fixedly connected to the bottom of the sleeve 31. A main float 331 is fixedly connected to the bottom of the main lower probe rod 33, and a sliding ring 341 slides on the surface of the fixed rod 3. A secondary lower probe rod 34 is fixedly connected to the surface of the sliding ring 341, and a secondary float 342 is fixedly connected to the bottom of the secondary lower probe rod 34. The main lower probe rod 33 and the secondary lower probe rod 34 are located in two adjacent preparation tanks 2, respectively. Figure 2 and Figure 3 As shown, under normal conditions, both the main float 331 and the auxiliary float 342 are located at the bottom of the preparation tank 2.

[0029] Specifically, when adding the two-component raw materials to the two preparation tanks 2 respectively, the slurry injected into the preparation tank 2 will cause the main float 331 and the auxiliary float 342 to float up with the liquid level. Furthermore, the main lower probe 33 and the auxiliary lower probe 34 will move upward synchronously, and respectively cause the sleeve 31 and the sliding ring 341 to move up a certain height on the surface of the fixed rod 3. The height of the upward movement is marked in real time by the scale line set on the surface of the fixed rod 3. The operator can intuitively and uniquely observe the current real-time slurry height in the two preparation tanks 2 at the same time through the fixed rod 3, which effectively improves the operating efficiency. The slurry can be stopped immediately after it reaches the predetermined scale, without the need for additional measurement by flow meter, scale and weighing scale, thus improving the mixing efficiency of the slurry.

[0030] Furthermore, both the main float 331 and the secondary float 342 are polystyrene foam blocks or polyurethane foam blocks. By setting the main float 331 and secondary float 342 with foam material, the buoyancy of the foam is stronger, which improves the buoyancy and floating applicability under different slurry environments.

[0031] The stirring structure includes a top frame 22 fixedly connected to the top of the preparation tank 2. A driving component 221 is installed on the top of the top frame 22. A stirring shaft 222 is fixedly connected to the output end of the driving component 221. Several stirring blades 223 are provided on the surface of the stirring shaft 222. Driven by the driving component 221, the stirring shaft 222 and the stirring blades 223 are rotated, thereby realizing the stirring and mixing of the sealing slurry in the preparation tank 2.

[0032] Furthermore, the drive unit 221 includes a servo motor and a reducer. The output end of the servo motor is connected to the input end of the reducer, and the output end of the reducer is connected to the stirring shaft 222. The reducer reduces the output speed of the servo motor to ensure the stability of the rotation of the stirring shaft 222.

[0033] The surface of the preparation tank 2 is provided with a discharge port 21, which is used to discharge the mixed slurry in the preparation tank 2. The discharge port 21 can be directly connected to a two-liquid mixing pump, so that the slurry in the two preparation tanks 2 can be directly exported, mixed, and directly injected into the hole for sealing through the two-liquid mixing pump.

[0034] Example 2:

[0035] Based on Embodiment 1, this embodiment of the invention discloses a sealing material mixing device, used to visually indicate the mixing ratio of slurry added to the two tanks during dual-tank pulping, such as... Figure 1-5 As shown, it includes a mixing structure used to adjust the volume of the solutions in the two preparation tanks 2 for mixing.

[0036] In this embodiment, the proportioning structure includes a rotating ring 32 sleeved on the surface of the fixed rod 3. The rotating ring 32 is rotatably connected to the surface of the sleeve 31. An adjusting plate 321 is fixedly connected to the bottom of the rotating ring 32. The surface of the adjusting plate 321 is provided with an inclined groove that matches the sliding ring 341. The sliding ring 341 directly abuts against the surface of the inclined groove.

[0037] Specifically, when the sealing grout for double-bucket grouting needs to be prepared according to a certain ratio, the amount of grout to be added from the larger proportion can be determined first. The first batch of grout raw material is added to the preparation bucket 2 on one side of the main lower probe rod 33. As the grout is added, the main float 331 gradually floats up with the grout, and the main lower probe rod 33 moves upward along with the sleeve 31, driving the rotating ring 32 and the adjusting plate 321 to move upward synchronously. Furthermore, the sliding ring 341 will also drive the auxiliary lower probe rod 34 to move upward by the same height. The amount of grout added is determined according to the scale line until the addition is complete. Then, by turning the rotating ring 32, it drives the adjusting plate 321 to rotate. The surface of the adjustment plate 321 is provided with a sloping groove, so the sliding ring 341 will move downward with the movement of the sloping groove. Furthermore, the ratio value, i.e. the grout ratio value required for double-bucket grouting, can be marked at the marked position on the sloping groove surface. After the sliding ring 341 moves to the predetermined ratio value position on the sloping groove surface, it means that the height of the auxiliary float 342 is the injection height of the second part of the grout raw material after the ratio is set. It can be directly injected into the preparation bucket 2 where the auxiliary lower probe rod 34 is located. The injection can be stopped after the height reaches the surface of the auxiliary float 342. The structure of this embodiment can conveniently realize the adjustment of the ratio value and the marking of the grouting height, effectively improving the efficiency of the double-bucket grouting and sealing grout ratio.

[0038] Furthermore, the inclined groove surface is provided with several positioning grooves 322 for the sliding ring 341 to be inserted into. After the sliding ring 341 is inserted into the positioning groove 322, it is more firmly fixed. Different ratio values ​​can be set at the positioning groove 322, making it easier to select the corresponding wallpaper for insertion.

[0039] like Figure 4 As shown, in this embodiment, a clamping assembly is also included. The clamping assembly includes a conical block 311 fixedly connected to the top of the sleeve 31, a rotating ring 32 sleeved on the outer peripheral surface of the conical block 311 and threadedly connected to the conical block 311, and the conical block 311 is a conical truncated cone shape that gradually widens from bottom to top.

[0040] Specifically, by rotating the rotating ring 32, the rotating ring 32 can be threaded onto the surface of the conical block 311. Since the conical block 311 is designed as a truncated cone shape that gradually widens from bottom to top, after the rotating ring 32 gradually tightens the conical block 311, it is clamped onto the surface of the fixed rod 3, thereby fixing the height of the sleeve 31. This prevents the movement of the grout from affecting the height of the main float 331 and the main lower probe 33, and improves the accuracy and stability of the grouting ratio indication.
