The production process of such a floor slab is relatively complicated. If it is made by hand, the efficiency is low and the labor intensity is high. In addition, manual production will also result in uneven forming of the board material, and the slurry cannot be reasonably recycled. Summary of the invention

[0003] In view of this, the present application provides a grouting system for a Class A thermal insulation and sound insulation floating floor, which can recycle the slurry and reduce the production cost while improving the production efficiency.

[0004] In order to achieve the above objectives, this application is implemented through the following technical solutions:

[0006] The casting mold comprises a box body, a cover plate arranged on the box body, and a locking device for fixing and connecting the box body and the cover plate. An inner cavity is formed inside the box body, and the lower surface of the inner cavity is a corrugated surface with alternating concave and convex shapes. A grouting port is arranged on the cover plate, and a grouting hole communicating with the inner cavity is arranged at the bottom of the box body.

[0007] The casting system also includes an aggregate recovery device, which includes an aggregate guide plate and an aggregate box arranged below the mold conveyor line. The aggregate guide plate is arranged to be inclined from top to bottom, and the upper end of the aggregate guide plate is hinged to the bracket of the conveyor line through a hinge structure, and the lower end of the aggregate box is also hinged to the aggregate box through a hinge structure. A frequency vibrator is also arranged on the aggregate guide plate to drive the aggregate guide plate to continuously vibrate and transport materials. The slurry flowing out of the slurry discharge hole of the box body falls onto the aggregate guide plate and flows to the aggregate box through the aggregate guide plate. A slurry pump is also arranged in the aggregate box, and a reflux pipe is connected between the slurry pump and the stirring and pressurizing device. The slurry in the aggregate box is returned to the stirring and pressurizing device through the slurry pump and the reflux pipe.

[0008] The above-mentioned grouting system of the A-class thermal insulation and sound insulation floating floor of the present application adopts the method of injecting excess slurry into the casting mold and discharging it from the slurry discharge hole, so that the cast product is more uniform, and the lower surface of the inner cavity is corrugated, which can form the required corrugated surface more uniformly compared to setting a corrugated surface on the lower surface of the cover plate, so that the slurry flows downward continuously. In addition, the slurry will flow onto the aggregate guide plate during the downward flow, and the aggregate guide plate will continue to shake under the drive of the frequency vibrator, so that the slurry flows to the aggregate box, and the slurry in the aggregate box is then pumped away by the slurry pump and flows into the stirring and pressurizing device for reuse, thereby reducing production costs.

[0009] In some embodiments, more than two casting molds constitute a mold group, and two adjacent casting molds of the same mold group are connected by a connecting structure so that the two casting molds maintain a preset spacing distribution. The number of grouting machines is more than two, and the spacing between two adjacent grouting machines is the same as the preset distance between two adjacent casting molds, thereby realizing multi-joint casting.

The advantage of such a setting is that the slurry will flow around after entering from the middle, so that the slurry can be poured more evenly. In this application, the lower surface of the inner cavity of the box body is corrugated, which can form the required corrugated surface more evenly than setting a corrugated surface on the lower surface of the cover plate. Therefore, the slurry continuously flows downward.

[0012] In some embodiments, a first level gauge and an observation window are further provided in the aggregate box. The level gauge is mainly used to determine the height of the slurry in the aggregate box, and the observation window is convenient for manual inspection of the specific situation in the aggregate box.

A second check valve is provided on the second pipeline. A stirrer is also provided inside the second barrel body.

[0014] The stirring and pressurizing device of this embodiment is a two-stage structure. The first stirring barrel is mainly used for stirring materials, and the secondary mixing, stirring and pressurizing kettle is mainly used for pressurizing and transporting the slurry. The first butterfly valve functions as a switch control, and the first check valve and the second check valve are used to prevent the reverse flow of materials.

[0015] In some embodiments, the grouting machine includes a grouting machine platform, a grouting bucket, a grouting cylinder, a grouting nozzle and a docking cylinder. The grouting bucket is arranged on the grouting machine platform. The grouting cylinder is used to pressurize the grouting bucket. The grouting bucket is connected to the grouting nozzle through a pipeline. The slurry in the grouting bucket flows to the grouting nozzle under pressure. The grouting nozzle is located above the mold conveyor line. The docking cylinder is installed on the grouting machine platform and is used to drive the grouting nozzle to rise and fall.

[0016] The use process of the grouting machine is as follows: when the mold group moves to the bottom of the grouting nozzle, the sensor can be used to determine whether the movement is in place, the docking cylinder drives the grouting nozzle to move down to align with the grouting port of the corresponding casting mold, the grouting cylinder moves down to apply pressure to the grouting bucket, and the slurry in the grouting bucket flows to the grouting nozzle through the pipeline, and flows from the lower opening of the grouting nozzle into the casting mold.

[0017] In some embodiments, the entry end of the mold conveyor line is an open bell mouth, which is mainly used to facilitate the entry of the mold set. Guide rail rollers are also provided on both sides of the mold conveyor line to facilitate the movement of the casting mold. The mold conveyor line can be a multiple chain, a conveyor chain or a roller conveyor line.

[0018] In some embodiments, the left and right side plates of the box body protrude downward from the bottom of the box body, and the mold conveying line is provided with two slide grooves, and the left and right side plates of the box body are respectively slidably arranged to sink into the two slide grooves to limit the left and right deviation of the casting mold, and the mold conveying line conveys the casting mold along the forward direction. The left and right side plates of the box body protrude downward to prevent the bottom of the box body from directly contacting the conveying line, and the two side plates can also cooperate with the slide grooves to prevent the box body from moving left and right.

[0019] It can be seen from the above technical solution that the present application has at least the following advantages and positive effects:

[0020] The above-mentioned grouting system of the A-class thermal insulation and sound insulation floating floor of the present application adopts the method of injecting excess slurry into the casting mold and discharging it from the slurry discharge hole, so that the cast product is more uniform, and the lower surface of the inner cavity is corrugated, which can form the required corrugated surface more uniformly compared to setting a corrugated surface on the lower surface of the cover plate, so that the slurry flows downward continuously.
