Description

Technical Field

[0001] This utility model relates to the field of building grouting technology, specifically to a grouting material heating device. Background Technology

[0002] Grouting material is formulated with high-strength materials as aggregates, cement as binder, and supplemented with substances that promote high fluidity, micro-expansion, and anti-segregation. At the construction site, the prepared grouting material is mixed with a certain amount of water and stirred evenly before use. Grouting material features good self-flowability, rapid hardening, early strength, high strength, no shrinkage, micro-expansion; it is non-toxic, harmless, non-aging, and does not pollute water quality or the surrounding environment. It also has good self-sealing properties and rust prevention. In terms of construction, it offers advantages such as reliable quality, reduced costs, shorter construction period, and ease of use. Chinese patent (authorization announcement number CN220549510U) discloses a grouting material heating device, including a transport vehicle, a heating and storage mechanism, and a control mechanism. The heating and storage mechanism includes a storage tank and a heating component. The storage tank is mounted on the transport vehicle for storing grouting material, and the heating component is located inside the storage tank for heating the grouting material. The heating component is electrically connected to the control mechanism. This device achieves automatic heating and temperature measurement through a heating component, preventing the grout from solidifying. An adjustment mechanism facilitates the tilting and emptying of remaining grout from the storage tank. A control mechanism controls the heating and storage of the grout, and adjusts the angle of the transport vehicle. The device is simple in structure, easy to operate, convenient to transport, and highly practical. This patented technology solves the current problem of grout being stored in plastic buckets, which easily solidifies during use, especially in cold winters when solidification is rapid, significantly reducing its effectiveness. Solidification also results in a small amount of grout remaining inside the plastic bucket, causing waste. Furthermore, during construction, workers must manually carry the plastic buckets to the designated construction location and manually empty the grout from the discharge port, which is time-consuming and labor-intensive.

[0003] However, in the existing technology, the heating of the grout heating rod is prone to uneven heating of the liquid grout, resulting in inconsistent quality of the grout during use. It is necessary to solve the problem of even heating of the grout in the existing technology.

[0004] Therefore, those skilled in the art have provided a grout heating device to solve the problems mentioned in the background art. Utility Model Content

[0021] The technical effects and advantages of this utility model are as follows:

[0022] This invention features uniform heating and insulation: A heater inside a hot water tank heats the water, and a circulating pump circulates the hot water between the heating ring pipe and the hot water tank, achieving overall heating of the inner wall space of the grouting tank. This method ensures uniform heating of the grout, avoiding localized overheating or undercooling, and helps maintain the stability of the grout's performance. Especially in low-temperature environments or projects with strict temperature requirements for the grout, it effectively prevents problems such as grout solidification and decreased fluidity due to temperature issues, ensuring smooth construction.

[0023] This invention features stable pressure discharge: A servo motor drives a screw, screw block, and pressure frame, causing the pressure plate to descend within the grouting tank. This applies stable pressure to the grout, allowing it to be smoothly discharged through the discharge pipe. This pressure discharge method provides relatively precise pressure control, ensuring the grout is discharged at the required pressure and flow rate. It meets the pressure and speed requirements of different construction scenarios, improving construction accuracy and efficiency, and ensuring the uniformity and density of the grouting operation.

One end of the heating ring pipe 202 is connected to a circulation pump 203, and the pumping end of the circulation pump 203 is connected to a hot water tank 204.

[0035] The other end of the heating ring pipe 202 is connected to the hot water tank 204; a heater 205 is installed inside the hot water tank 204. A transmission rod 206 is rotatably mounted inside the grouting tank 201, and the top end of the transmission rod 206 rotatably passes through the outer wall of the grouting tank 201 and is connected to a servo motor 216. The servo motor 216 is fixedly installed on the top outer wall of the grouting tank 201 and is used to actively drive the transmission rod 206 to rotate.

[0036] The grouting tank 201 is sealed and movably fitted with a pressure plate 210 that is sleeved on the outside of the transmission rod 206. A pressure applying frame 211 that is sealed and movably extends through the top of the grouting tank 201 is fixedly installed on the surface of the pressure plate 210. A screw block 212 is integrally fixed at one end of the pressure applying frame 211 away from the pressure plate 210. A screw 213 is provided with a screw drive inside the screw block 212.

[0037] The bottom end of the grouting tank 201 is connected to a discharge pipe 208, and a hand valve 209 is installed on the discharge pipe 208. The bottom end of the transmission rod 206 is fixedly fitted with a mixing frame 207 located at the bottom inner side of the grouting tank 201.

[0038] According to the above embodiments, the working principle of this invention is as follows:

[0039] A feed hopper is connected through the side wall of the grouting tank 201. The concrete raw materials and water are placed into the grouting tank 201 through the feed hopper.
