Detailed Implementation
[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0024] like Figures 1-3 As shown, the sealing composite grouting pump mixing device of this utility model embodiment includes a mixing tank 1, a support frame 2, a pneumatic pump 3, and a mixing component 4. The support frame 2 is located at the top opening of the mixing tank 1. The pneumatic pump 3 is mounted on the support frame 2. The mixing component 4 includes a mixing rod 41 and a mixing blade 42. One end of the mixing rod 41 (e.g., ...) Figure 1 The upper end of the stirring rod 41 shown is detachably connected to the pneumatic pump 3, which drives the stirring rod 41 to rotate. The stirring blade 42 is located at the other end of the stirring rod 41 (e.g., Figure 1 The stirring rod 41 shown below has a lower end, and the stirring blade 42 has a thickness of 2mm-5mm.
[0025] The sealing composite material grouting pump mixing device of this utility model has a mixing blade 42 thickness controlled between 2mm and 5mm, which improves the structural strength of the mixing blade 42, ensures that the mixing blade 42 can easily mix the slurry in the mixing tank 1 evenly, improves the mixing efficiency of the mixing device, reduces the adhesion of sealing material to the tank wall or the sedimentation at the bottom of the tank, and reduces material loss. The mixing rod 41 is detachably connected to the pneumatic pump 3, which can be disassembled and installed, making it easy to replace, maintain and transport. In addition, the mixing device has a simple structure and saves manufacturing costs.
[0026] Specifically, the stirring blade 42 has a thickness of 3mm. Compared with the paddle in the prior art, the stirring blade 42 has increased thickness, increased durability, increased power when stirring slurry, shortened preparation time of composite sealing material, and avoided material loss caused by small paddles failing to fully stir the grouting material adhering to the barrel wall and bottom.
[0027] Specifically, the pneumatic pump 3 is a pneumatic handheld drill used in coal mines, with a rated torque of 65 N·m, a rated speed greater than 380 r / min, and a power of 2.5 kW. This increases the stirring power, shortens the preparation time of the sealing grout, and improves the preparation efficiency of the sealing grout. Compared to existing grouting pumps, the pneumatic pump 3 in this embodiment is smaller, lighter, easier to operate and maintain. Furthermore, it uses a metal motor gear, resulting in a longer service life, stable operation, high reliability, a reasonable structure, and strong adaptability, reducing the time spent on maintenance and parts replacement, thus saving time and money.
[0028] In some embodiments, the support frame 2 includes support rods 21 and support plates 22. There are two support rods 21, which are arranged opposite to each other and spaced apart. The support plate 22 is disposed on the support rods 21 and has through holes 221. The pneumatic pump 3 is connected to the stirring component 4 through the through holes 221.
[0029] Specifically, the support rod 21 is located in the middle of the two support rods 21 and extends along the extension direction of the support rod 21. The through hole 221 is located in the middle of the support plate 22. The central axis of the through hole 221 is collinear with the central axis of the mixing tank 1, so as to ensure that the mixing component 4 mixes the sealing slurry evenly in the mixing tank 1.
[0030] In some embodiments, the support rod 21 has a thickness of 4mm-7mm and a width of 30mm-70mm.
[0031] Specifically, when the thickness dimension of the support rod 21 is less than 4mm, the structural strength of the support rod 21 is low. When the thickness dimension of the support rod 21 is greater than 7mm, the mass of the support rod 21 is large, resulting in high cost. Preferably, the thickness dimension of the support rod 21 is 5mm, which results in high structural strength, long service life, and cost savings.
[0032] When the width dimension of the support rod 21 is less than 30mm, the support rod 21 is relatively narrow, resulting in lower connection strength with the support plate 22 and affecting its service life. When the width dimension of the support rod 21 is greater than 70mm, the support rod 21 is relatively wide, leading to higher costs. Preferably, the support plate 22 has a width dimension of 50mm, resulting in high structural strength, long service life, and cost savings.
[0033] The support rod 21 extends along the diameter of the mixing tank 1, and its length dimension is larger than the diameter of the mixing tank 1. Both ends of the support rod 21 extend beyond the outer circumference of the mixing tank 1. The support rod 21 is made of iron plate, which has high structural strength and a long service life.
[0034] In some embodiments, the support plate 22 has a thickness of 4mm-7mm.
[0035] Specifically, when the thickness dimension of the support plate 22 is less than 4mm, the structural strength of the support plate 22 is low. When the thickness dimension of the support plate 22 is greater than 7mm, the support plate 22 has a large mass, high cost, and applies greater pressure to the support rod 21, making the support rod 21 prone to deformation and affecting the stability of the pneumatic pump 3. Preferably, the thickness dimension of the support plate 22 is 5mm, which results in high structural strength, long service life, and cost savings. The support plate 22 is made of iron plate, which further improves the structural strength and extends the service life.
[0036] In some embodiments, the support frame 2 further includes a limiting block 23, which is provided at the end of the lower surface of the support rod 21 and is located inside the mixing tank 1.
[0037] Specifically, there are four limiting blocks 23, and each support rod 21 has one at the end of its lower surface and is located inside the mixing tank 1, so as to ensure that the support rod 21 does not easily slip off the mixing tank 1.
[0038] In some embodiments, the sealing composite material grouting pump mixing device further includes a sleeve 5, which is disposed on the upper surface of the support plate 22, and the pneumatic pump 3 is inserted inside the sleeve 5 to support and protect the pneumatic pump 3.
[0039] In some embodiments, the sealing composite material grouting pump mixing device further includes a connector 7, which includes a connector cap 71 and a connector rod 72. The connector cap 71 is located below the support plate 22 and is connected to the pneumatic pump 3. The connector rod 72 is detachably located inside the connector cap 71 and is detachably connected to one end of the mixing rod 41, which facilitates disassembly, replacement and maintenance.
[0040] In some embodiments, the peripheral wall of the connecting cap 71 has two oppositely arranged mounting holes 711. The mounting holes 711 extend obliquely from the lower end of the connecting cap 71 toward the upper end of the connecting cap 71 and have an arc. The connector 7 also includes two mounting rods 73, which are provided on the connecting rod 72. The two mounting rods 73 are arranged opposite to each other and correspond one-to-one with the two mounting holes 711. The mounting rods 73 are disposed in the mounting holes 711 and are not easily dislodged. The outer peripheral surface of the connecting rod 72 has external threads, and the connecting rod 72 is threadedly connected to the stirring rod 41.
[0041] Specifically, the extension direction of the mounting rod 73 is orthogonal to the extension direction of the connecting rod 72, making the mounting rod 73 and the connecting rod 72 roughly form a cross shape. The lower end of the mounting hole 711 passes through the lower edge of the peripheral wall of the connecting cap 71. The mounting rod 73 enters the mounting hole 711 from the lower end of the mounting hole 711. The mounting hole 711 has an arc shape to ensure that the mounting rod 73 is not easily dislodged from the mounting hole 711. The inner peripheral surface of the upper end of the stirring rod 41 has an internal thread that mates with the external thread on the outer peripheral surface of the connecting rod 72, so that the stirring rod 41 and the connecting rod 72 are threadedly connected, making the connection simple and firm.
[0042] In some embodiments, the pneumatic pump 3 has an air inlet 31 and a water inlet 32. Air is supplied to the pneumatic pump 3 through the air inlet 31 to drive the pneumatic pump 3 to operate. The water inlet 32 is connected to the mixing tank 1, and water is supplied to the mixing tank 1 through the water inlet 32 to facilitate the mixing of the sealing material by the stirring blades 42.
[0043] In some embodiments, the grouting pump mixing device for sealing composite materials further includes an air inlet pipe 61 and a water inlet pipe 62. The air inlet pipe 61 is connected to the air inlet 31 to supply air to the pneumatic pump 3, and the water inlet pipe 62 is connected to the water inlet 32 to supply water to the mixing tank 1. The operator can operate the air supply switch and the water supply switch at the same time, saving manpower.
[0044] In some embodiments, the stirring rod 41 has a channel (not shown) that communicates with the water inlet 32, through which water entering the pneumatic pump 3 can enter the stirring tank 1.
