[0018] A method for using a foaming device for producing bubble-mixed lightweight soil comprises the following steps:

[0019] S1: First, raw soil, solidifying material, and foaming agent are prepared in sequence according to needs. The raw soil and solidifying material are conveyed by a screw conveyor, and the foaming agent is conveyed by a liquid supply water pump. During conveying, the conveying amount of each screw conveyor and liquid supply water pump is controlled according to the ratio. The raw soil and solidifying material will be conveyed to the receiving tray of the corresponding layer, and the foaming agent will be conveyed to the liquid storage ring by the liquid supply water pump, completing the expected preparation work;

[0020] S2: Then the hollow shaft motor is started to drive the rotating rod to rotate, so that the rotating frame rotates, and the discharging paddle discharges the material in the current receiving tray, so that the material is pushed out in a concentrated manner. After being pushed out, the driving rotating rod is rotated to make the stirring blade stir the concentrated material, wherein the foaming agent is sprayed through the spray head, so that the raw soil, the solidifying material and the foaming agent are mixed together, so as to facilitate the subsequent foaming reaction;

[0021] S3: After the discharge and mixing, the material will be received by the receiving funnel, and the material will enter the receiving tube. Then, the compressed air will enter the docking hole from the gas transmission channel, so that the gas will enter the distribution channel, and each one-way exhaust hole will exhaust outward, realizing large-area contact;

[0022] S4: As the amount of material increases, the material will be squeezed downward. By providing multiple layers of extension sheets, the air contact area is increased. During the extrusion process, the material will approach by itself. By driving the rotating rod to rotate continuously, the discharge thread blade will rotate accordingly. The accumulated material will be discharged upward in sequence by using the discharge thread blade inside the discharge barrel, and fall into the lower receiving barrel for further reaction.

[0023] S5: The material after the reaction will be discharged from the bottom of the processing pipeline. Before the discharge, a container needs to be prepared and placed at the bottom of the processing pipeline. When the material is discharged, the air will be exhausted downward through the air transmission channel, so that the final air will be sprayed to the material inside the container along the distribution nozzle to complete the foaming process of the lightweight soil.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. Start the hollow shaft motor to drive the driving rod to rotate, so that the first mounting ring rotates, and the rotating frame on the first mounting ring drives the discharging paddles of each layer to rotate, and finally the discharging paddles discharge the materials in each receiving tray to realize automatic loading. The above-mentioned loading method can make different materials mixed together when discharged, so as to facilitate subsequent mixing. Then, the materials fall through the stirring blades, and the materials are further mixed under the action of the stirring blades, so that the raw soil, curing material and foaming agent are mixed together, wherein the proportional feeding is realized by controlling the screw conveyor and the liquid supply pump.

[0026] 2. During foaming, compressed air is discharged into the air delivery channel through the air pump, and the driving rod and the air pump are connected by an adapter sleeve, so as not to affect the rotation drive of the driving rod. After the gas is discharged, it will pass through the docking hole, the distribution channel and finally be discharged from the one-way exhaust hole in turn to achieve continuous air supply. The remaining air will be discharged from the distribution nozzle to assist the material in the container below to increase air contact.

[0027] 3. The present application is designed to discharge materials vertically, so that the materials will be discharged downward continuously, thereby improving the discharge efficiency. In order to ensure that the materials can be fully reacted during continuous discharge, two sets of mixing components are provided. When the materials enter the receiving tube, they will contact with the multi-layer extension sheets, and utilize the multiple one-way exhaust holes on the surface of the extension sheets to achieve full reaction.

[0028] 4. A discharge thread blade is provided on the driving rod body, and the discharge thread blade is located inside the discharge barrel, so that the discharge thread blade can discharge the material entering the discharge barrel upward in sequence to realize the falling of the material. Through the above structure, while ensuring that the material can fall, the time the material stays in the receiving tube can be controlled. The foaming and discharge of the material can be realized in time according to the proportion required, so that the efficiency of the present application in the foaming process is improved.

[0029] 5. The lower guard plate is supported by the support spring so that the discharge barrel will press upward against the receiving tube, so that the bottom opening of the receiving tube fits with the inclined top plate, thereby adjusting the distance between the inclined top plate and the bottom opening of the receiving tube. The heavier the weight, the more the support spring contracts, thereby increasing the distance, thereby avoiding the situation where the material is discharged when there is less material, resulting in insufficient reaction time.

[0040] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] In this embodiment, the discharge assembly 3 includes a plurality of receiving trays 301, the diameter of each receiving tray 301 decreases from bottom to top, and a plurality of discharge holes 3011 are opened on the inner wall of each receiving tray 301. A liquid storage ring 304 is fixedly installed on the body of the processing pipeline 2 and located at the lower side of the receiving tray 301, and a spray head 3042 is arranged around the inner wall of the liquid storage ring 304;

A liquid infusion pipe 3041 is fixedly installed on the outside of the liquid storage ring 304, and the other end of the liquid infusion pipe 3041 is connected to the liquid supply water pump.

[0044] In the present application, each receiving tray 301 has a rotating opening 3012, a rotating frame 3031 is rotatably installed inside the rotating opening 3012, a plurality of discharge paddles 3032 for discharging materials are fixedly installed at the bottom of the rotating frame 3031, a first mounting ring 303 is fixedly installed between the plurality of rotating frames 3031, and the first mounting ring 303 is fixedly installed on the shaft of the driving rotating rod 403;

[0045] The shaft of the driving rotating rod 403 is fixedly mounted with a second mounting ring 305 , and a plurality of stirring blades 3051 are fixedly mounted on the outer side of the second mounting ring 305 . The stirring blades 3051 are located below the spray head 3042 and the discharge hole 3011 .

[0046] In order to realize automatic loading, the hollow shaft motor 402 is started to drive the driving rod 403 to rotate, so that the first mounting ring 303 rotates, and the rotating frame 3031 on the first mounting ring 303 drives the discharge paddles 3032 of each layer to rotate, and finally the discharge paddles 3032 discharge the materials in each receiving tray 301 to realize automatic loading. The above-mentioned loading method can make different materials mixed together when discharged, so as to facilitate subsequent mixing. Then, the materials fall through the stirring blades 3051, and the materials are further mixed under the action of the stirring blades 3051, so that the raw soil, curing material and foaming agent are mixed together, and the proportional feeding is realized by controlling the screw conveyor and the liquid supply pump.

[0047] In this embodiment, the gas delivery component 4 includes a base 401, which is fixedly mounted on the upper surface of the receiving plate 301 at the upper end. A hollow shaft motor 402 is fixedly mounted on the upper end of the base 401, and a driving rod 403 is fixedly mounted inside the hollow shaft motor 402. A gas delivery channel 405 is opened in the air inside the driving rod 403. A distribution nozzle 404 is connected to the bottom of the driving rod 403, and the upper end of the driving rod 403 is rotatably connected to the air pump through an adapter sleeve.

[0048] During foaming, compressed air is discharged into the air delivery channel 405 through the air pump, wherein the driving rotating rod 403 and the air pump are connected by an adapter sleeve, so as not to affect the rotation drive of the driving rotating rod 403. After the gas is discharged, it will pass through the docking hole 406, the distribution channel 7041 and finally be discharged from the one-way exhaust hole 7042 to achieve continuous air supply, wherein the remaining air will hit the distribution nozzle 404 to assist in jetting the material in the container below to increase air contact.

[0049] In the present application, the mixing assembly 7 includes two sets of fixing frames 701, the fixing frames 701 are fixedly mounted on the inner wall of the processing pipeline 2, a receiving tube 702 is fixedly mounted inside the fixing frames 701, and a receiving funnel 7021 is fixedly mounted on the upper end of the receiving tube 702;

[0050] An extension piece 704 is fixedly installed on the rod body of the driving rotating rod 403 located inside the receiving tube 702, and a distribution channel 7041 is opened inside each extension piece 704. The upper and lower surfaces of the distribution channel 7041 are respectively provided with a plurality of one-way exhaust holes 7042 for exhaust. A docking hole 406 is opened on the inner wall of the gas transmission channel 405, and the docking hole 406 is docked with the distribution channel 7041.

[0051] In order to achieve uniform gas contact without affecting the foaming efficiency, the present application is designed to discharge the material vertically so that the material will be discharged downward continuously, thereby improving the discharge efficiency. In order to ensure that the material can be fully reacted during continuous feeding, two sets of mixing components 7 are provided. When the material enters the receiving tube 702, it will contact the multi-layer extension sheet 704, and utilize the multiple one-way exhaust holes 7042 on the surface of the extension sheet 704 to achieve full reaction.

[0052] In the specific configuration, the driving rotating rod 403 shaft sealing sleeve located at the lower side of the receiving tube 702 is provided with a discharge barrel 703, the discharge barrel 703 is provided with a guide groove 7031 for discharging materials, and the middle of the discharge barrel 703 is provided with a rotation through hole 7035, and the rotation through hole 7035 is sealably interlaced with the driving rotating rod 403 shaft;

[0053] The shaft of the driving rotating rod 403 is provided with a discharge thread leaf 7032 , and the bottom of the discharge barrel 703 is provided with an inclined top plate 7033 for matching the bottom of the receiving cylinder 702 .

[0054] In order to realize material discharge, a discharge thread leaf 7032 is provided on the rod body of the driving rotating rod 403, and the discharge thread leaf 7032 is located inside the discharge barrel 703, so that the discharge thread leaf 7032 can discharge the material entering the discharge barrel 703 upward in sequence, thereby realizing the falling of the material. Through the above structure, while ensuring that the material can fall, the time of the material inside the receiving tube 702 can be controlled, and the foaming and discharge of the material can be realized in time according to the proportion required, so that the efficiency of the present application in the foaming process is improved.

[0055] It should be noted that a lower guard plate 7034 is fixedly installed at the bottom of the discharge barrel 703, and a limiting support plate 705 is fixedly installed on the rod body of the driving rotating rod 403 located at the lower side of the lower guard plate 7034. A supporting spring 7051 is fixedly installed on the upper end of the limiting support plate 705, and the upper end of the supporting spring 7051 supports the lower guard plate 7034.

[0056] In order to match the weight of the material for unloading, the lower guard plate 7034 is supported by the support spring 7051, so that the discharge barrel 703 will push the receiving tube 702 upward, so that the bottom opening of the receiving tube 702 is fitted with the inclined top plate 7033, thereby adjusting the distance between the inclined top plate 7033 and the bottom opening of the receiving tube 702. The heavier the weight, the more the support spring 7051 shrinks, thereby increasing the distance, thereby avoiding the situation where the material will be discharged when the material is small, resulting in insufficient reaction time.

[0057] Among them, several control valves 6 are respectively installed on the rod body of the driving rotating rod 403, and a baffle 601 for preventing materials from falling is fixedly installed on the upper end of each control valve 6. Several holding holes 602 for personnel to rotate the driving rotating rod 403 are opened on the outer side of the baffle 601. An adjusting knob 603 is set at the control rod of the control valve 6, and a docking socket 604 is opened on the surface of the adjusting knob 603. A warehouse door 5 is sealed on the surface of the processing pipeline 2.

[0058] Due to different material proportions, the compressed air required for contact is also different. In order to avoid excessive injection of compressed air, the flow rate of the control valve 6 is adjusted by opening the compartment door 5 and using a tool to dock and rotate the docking socket 604 to ensure that it matches the required air flow. The direction of the adjusting knob 603 can be adjusted by holding and rotating the holding hole 602 to ensure that the tool can dock with it.

[0059] A method for using a foaming device for producing bubble-mixed lightweight soil comprises the following steps:

[0060] S1: First, raw soil, solidifying material, and foaming agent are prepared in sequence according to needs. The raw soil and solidifying material are conveyed by a screw conveyor, and the foaming agent is conveyed by a liquid supply water pump. During conveying, the conveying amount of each screw conveyor and liquid supply water pump is controlled according to the ratio. The raw soil and solidifying material will be conveyed to the receiving tray 301 of the corresponding layer, and the foaming agent will be conveyed to the liquid storage ring 304 by the liquid supply water pump, completing the expected preparation work;

[0061] S2: Then the hollow shaft motor 402 is started to drive the rotating rod 403 to rotate, so that the rotating frame 3031 rotates, and the discharging paddle 3032 discharges the material in the current receiving tray 301, so that the material is pushed out in a concentrated manner. After being pushed out, the driving rotating rod 403 is rotated to make the stirring blade 3051 stir the concentrated material, wherein the foaming agent is sprayed through the spray head 3042, so that the raw soil, the solidifying material and the foaming agent are mixed together, so as to facilitate the subsequent foaming reaction;

[0062] S3: After the discharge and mixing, the material will be received by the receiving funnel 7021, and the material will enter the receiving tube 702, and then the compressed air will enter the docking hole 406 from the gas transmission channel 405, so that the gas will enter the distribution channel 7041, so that each one-way exhaust hole 7042 will exhaust outward, realizing large-area contact;

[0063] S4: As the amount of materials increases, the materials will be squeezed downward. The multi-layer extension sheet 704 is provided to increase the air contact area. During the squeezing process, the materials will approach by themselves. By driving the rotating rod 403 to rotate continuously, the discharge thread leaf 7032 will rotate accordingly. The discharge thread leaf 7032 inside the discharge barrel 703 is used to discharge the accumulated materials upward in sequence, and the materials fall into the lower receiving cylinder 702 for further reaction.

[0064] S5: The material after the reaction will be discharged from the bottom of the processing pipeline 2. Before the discharge, a container needs to be prepared and placed at the bottom of the processing pipeline 2. When the material is discharged, the gas will be exhausted downward through the gas transmission channel 405, so that the final air will be sprayed to the material inside the container along the distribution nozzle 404 to complete the foaming process of the lightweight soil.

[0065] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.

10. The method for using the foaming device for producing bubble-mixed lightweight soil according to claim 1, characterized in that: The steps include: S1: First, raw soil, solidifying material, and foaming agent are prepared in sequence according to needs. The raw soil and solidifying material are conveyed by a screw conveyor, and the foaming agent is conveyed by a liquid supply water pump. During conveying, the conveying amount of each screw conveyor and liquid supply water pump is controlled according to a ratio. The raw soil and solidifying material will be conveyed to a receiving tray (301) of a corresponding layer, and the foaming agent will be conveyed to a liquid storage ring (304) by the liquid supply water pump, thereby completing the expected preparation work; S2: Then, the hollow shaft motor (402) is started to drive the rotating rod (403) to rotate, so that the rotating frame (3031) rotates, and the material discharge paddle (3032) discharges the material inside the current receiving tray (301), so that the material is pushed out in a concentrated manner. After being pushed out, the driving rotating rod (403) is rotated to cause the stirring blade (3051) to stir the concentrated material, wherein the foaming agent is sprayed out through the spray head (3042), so that the raw soil, the solidifying material, and the foaming agent are mixed together to facilitate the subsequent foaming reaction; S3: After the discharge and mixing, the material will be received by the receiving funnel (7021), and the material will enter the receiving tube (702), and then the compressed air will enter the docking hole (406) from the gas transmission channel (405), so that the gas will enter the distribution channel (7041), so that each one-way exhaust hole (7042) will exhaust outward, achieving large-area contact; S4: As the amount of material increases, the material will be squeezed downward. By providing a multi-layer extension sheet (704), the air contact area is increased. During the squeezing process, the material will approach by itself. By driving the rotating rod (403) to rotate continuously, the discharge thread leaf (7032) will rotate accordingly. The discharge thread leaf (7032) inside the discharge barrel (703) is used to discharge the accumulated material upward in sequence, and the material falls to the lower receiving barrel (702) for further reaction. S5: The material after the reaction is completed will finally be discharged from the bottom of the processing pipeline (2). Before the discharge, a container needs to be prepared and placed at the bottom of the processing pipeline (2). When the material is discharged, the gas will be exhausted downward through the air supply channel (405), so that the final air will be sprayed to the material inside the container along the distribution nozzle (404), completing the foaming process of the lightweight soil.
