Description

Technical Field

[0001] This invention relates to the field of combined packing equipment technology, and in particular to a vertical combined packing equipment and its usage method. Background Technology

[0002] During engineering construction, soft-fluid plastic cohesive soil needs to be filled into the ground as a foundation. However, in karst topography, problems such as grout leakage, hole collapse, drill jamming, hole deviation, and concrete settlement during and after pouring can easily occur. These problems can even lead to a reduction in the bearing capacity of the pile foundation and uneven settlement of the foundation, resulting in huge economic losses and safety accidents. The construction of vertical lightweight foamed soil filler can better guide the construction, reduce the use of basic farmland, alleviate the construction difficulties caused by karst, reduce safety risks during construction, accelerate the construction process, and improve economic benefits. It has important theoretical guiding significance and application value for actual engineering.

[0003] For example, the invention disclosed in CN110451861B discloses a method for preparing lightweight foamed concrete, including the following steps: pre-forming concrete slurry; preparing a first foam body by diluting a foaming agent in a first proportion, and preparing a first foamed concrete slurry through the first foam body; preparing a second foam body by diluting the foaming agent in a second proportion, and preparing a second foamed concrete slurry through the second foam body; injecting the second foamed concrete slurry into a mold to a first height, and then injecting the first foamed concrete slurry onto the second foamed concrete slurry to the forming height; sending the formed foamed concrete into a standard curing room for curing, and demolding after the curing time is reached. The lightweight foamed concrete preparation method of this invention can achieve a more uniform pore size distribution, thereby improving the performance of lightweight foamed concrete.

[0004] However, there are still some shortcomings in the existing technology when using the corresponding equipment to produce lightweight foamed concrete:

[0005] 1. When pouring lightweight foamed concrete, it is necessary to pour the second foamed concrete slurry first and then pour the first foamed concrete slurry. However, the first and second foamed concrete slurries are made in the same mixing equipment. When the previous foamed concrete slurry remains in the mixing equipment, it will affect the preparation of the subsequent foamed concrete slurry, which in turn affects the change in the pore size of the foamed concrete slurry and affects the performance of lightweight foamed concrete.

[0006] 2. When mixing concrete and foaming agent, the foaming agent is directly added to the equipment and stirred with the concrete. In order to fully mix the foaming agent and concrete, a long stirring operation is required, which reduces the efficiency of foamed concrete slurry preparation.

[0007] To address the aforementioned problems, this invention proposes a vertical combined packing device and its usage method. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to clean the interior of mixing equipment in a timely manner, the need for long-term mixing operations, and the low efficiency of foamed concrete slurry preparation. This invention proposes a vertical combined packing device and its usage method.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A vertical combined packing device includes a lower support, an upper support fixed to the top of the lower support by bolts, a mixing tank fixed to the top of the lower support by bolts, and a concrete tank and two preparation tanks fixed to the top of the upper support by bolts.

[0011] The mixing structure is set inside the preparation tank and the concrete tank for preparing concrete and preparing diluted foaming agent;

[0012] The spraying structure is set inside the mixing tank to uniformly mix the diluted foaming agent with the concrete inside the mixing tank.

[0013] A cleaning structure, located inside the mixing chamber, is used for cleaning the interior of the mixing chamber.

[0014] In one possible design, the mixing structure includes a U-shaped rod rotatably connected inside a concrete box. Multiple mixing blades are bolted to the outer wall of the U-shaped rod. A connecting rod is rotatably fitted onto the outer wall of the U-shaped rod. One end of the connecting rod is rotatably connected to a rack, and one end of the rack slides through the concrete box in a sealed manner. Mixing rods are rotatably connected to both preparation boxes, with the tops of both mixing rods extending above the preparation boxes. The two mixing rods are connected by a belt and pulley drive. A gear is bolted to the top of one of the mixing rods, and the rack and gear mesh. The U-shaped rod is driven to rotate by a motor, mixing the cement and sand in the concrete box to form concrete. The interaction between the U-shaped rod and the connecting rod drives the rack to rotate reciprocally, which in turn drives the mixing rod to rotate reciprocally via the gear. The two mixing rods are connected by a belt and pulley drive, thus simultaneously mixing different concentrations of foaming agent dilution in the two preparation boxes while the U-shaped rod is mixing the concrete.

[0015] In one possible design, the spraying structure includes a rotating rod rotatably connected to the inner wall of the bottom of the mixing tank. The outer wall of the rotating rod is provided with multiple blades. A fixed frame is fixedly connected to the top of the upper support. The top of the rotating rod rotatably passes through the fixed frame and is fixedly connected to a first synchronous pulley. A second synchronous pulley is fixed to the outer wall of one of the mixing rods. The first and second synchronous pulleys are connected by a synchronous belt drive. The bottom of the concrete box is connected to the mixing tank through an injection pipe. The rotating rod is driven to rotate by the cooperation of the first synchronous pulley, the second synchronous pulley, and the synchronous belt. The rotating rod can fully mix the concrete with the foaming agent entering the mixing tank to prepare lightweight foamed concrete.

[0016] In one possible design, the spraying structure further includes a rectangular trough positioned at the top of the mixing tank. A solution transfer ring is fixedly connected within the rectangular trough, and the top end of a rotating rod passes through the solution transfer ring. Multiple electromagnetic spray guns are rotatably connected to the bottom of the solution transfer ring via a base, and these electromagnetic spray guns are arranged in a ring around the rotating rod. Each of the electromagnetic spray guns has a pull rope at its top, and the bottom end of each pull rope is anchored to the same lifting and supporting ring, which is fitted onto the outer wall of the rotating rod. A fixing ring is fixed to the outer wall of the rotating rod, located below the lifting and supporting ring. Multiple negative magnets are fixedly connected to the top of the fixing ring, and multiple positive magnets are fixedly connected to the bottom of the lifting and supporting ring. The two preparation boxes are equipped with a positive and a negative magnet, and the bottom of each box is connected to the rotating ring in the solution through a first drain pipe. The rotating rod drives the fixed ring and the negative magnet to rotate. When the negative magnet and the positive magnet are misaligned, the lifting and supporting ring moves down, pulling the electromagnetic spray gun. When the positive magnet and the negative magnet are aligned, the repulsive force between them pushes the lifting and supporting ring up, and the electromagnetic spray gun resets. As the fixed ring rotates, the electromagnetic spray gun can swing back and forth. Thus, when the rotating rod and blades are mixing the concrete, the diluted foaming agent can be evenly sprinkled on the concrete, thereby quickly completing the mixing of concrete and foaming agent and improving the preparation efficiency of foamed concrete slurry.

[0017] In one possible design, the cleaning structure includes a cleaning ring slidably connected to the inner wall of the mixing tank. Connecting blocks are fixedly connected to the inner walls of the two adjacent sides of the cleaning ring. Ropes are anchored to the tops of both connecting blocks, and the tops of both ropes are anchored to the same iron nut ring. A strong magnet that mates with the iron nut ring is fixedly connected to the bottom of the fixing frame. The outer wall of the rotating rod has a threaded section, and the rotating rod is threadedly connected to the iron nut ring through the threaded section. Rotation of the rotating rod causes the iron nut ring to move downwards. The downward movement of the cleaning ring scrapes away residual foamed concrete slurry from the inner wall of the mixing tank, preventing residual foamed concrete slurry from affecting subsequent foamed concrete slurry preparation.

[0018] In one possible design, the cleaning structure further includes a sliding plate slidably connected within the mixing tank. Multiple springs are fixedly connected to the bottom inner wall of the mixing tank, with the tops of each spring fixedly connected to the bottom of the sliding plate. A first contact piece is bolted to the bottom inner wall of the mixing tank, and a second contact piece, cooperating with the first contact piece, is bolted to the bottom of the sliding plate. The second contact piece is electrically connected to a strong magnet. The bottom end of the rotating rod penetrates the sliding plate. Under the influence of the concrete's gravity, the sliding plate moves downwards, causing the first and second contact pieces to contact each other. The strong magnet generates an upward magnetic attraction on the iron nut ring, disengaging the iron nut ring from the threaded section. This facilitates the mixing of concrete and foaming agent by the rotating rod. After the foamed concrete slurry is discharged from the mixing tank, the sliding plate returns to its original position, and the iron nut ring begins to engage with the threaded section, facilitating subsequent cleaning of the mixing tank's inner wall. Therefore, both the preparation of the foamed concrete slurry and the cleaning of the mixing tank's inner wall are achieved.

[0019] In one possible design, the top of the rotating ring in the solution is provided with a second drain pipe, which is connected to an external water source. The bottom of the rotating ring in the solution is fixed with multiple sliding rods by bolts, and the bottom end of the sliding rods slides into the lifting and supporting ring. A limit ring is fixed to the outer wall of the rotating rod, and the limit ring is located between the fixed ring and the lifting and supporting ring. The limit ring can limit the upper part of the lifting and supporting ring, and the sliding rods can make the lifting and supporting ring slide vertically. In addition, when cleaning the inside of the mixing tank, the second drain pipe ensures the cleanliness of the inside of the mixing tank.

[0020] In one possible design, the rectangular groove is provided with two guide wheels for guiding the rope. A discharge pipe is fixedly inserted through the sliding plate, with the top end of the discharge pipe flush with the top end of the sliding plate. The bottom end of the discharge pipe slides through the bottom inner wall of the mixing tank.

[0021] In one possible design, a storage tube is bolted to one side of each of the two preparation boxes, and a scale is bolted to one side of the storage tube. A liquid guide tube is provided at the bottom of the storage tube and is connected to the preparation box. A valve is provided on the outer wall of the liquid guide tube. The scale can be used to determine the volume of foaming agent in the storage tube, thereby making it easier to prepare foaming agent dilutions of different concentrations.

[0022] This application discloses a method of using a vertical combined packing device, comprising the following steps:

[0023] S1. Cement and sandy soil are put into the concrete box. Then, equal amounts of water are injected into the two preparation boxes, and foaming agent of different volumes is injected into the two storage tubes respectively. The volume of foaming agent in the storage tubes can be determined by the scale. Thus, foaming agent dilutions of different concentrations can be obtained in the two preparation boxes.

[0024] S2. The U-shaped rod is driven by a motor to rotate. The U-shaped rod mixes the cement and sandy soil in the concrete box to form concrete. The U-shaped rod and the connecting rod work together to drive the rack to rotate back and forth. The rack drives the mixing rod to rotate back and forth through the gear. The two mixing rods are connected by a belt and pulley. Thus, when the U-shaped rod finishes mixing the concrete, it can simultaneously mix the foaming agent dilution liquid of different concentrations in the two preparation boxes.

[0025] S3. Concrete from the concrete box is injected into the mixing tank through the injection pipe. Foaming agent dilution from one of the preparation tanks is injected into the solution rotating ring through the first drainage pipe. The sliding plate moves downwards under the weight of the concrete, compressing the spring. The first and second contact plates collide, and the strong magnet generates an upward magnetic attraction on the iron nut ring, causing it to disengage from the threaded section. At this point, the first and second synchronous pulleys and the synchronous belt drive the rotating rod to rotate. The rotating rod drives the fixed ring to rotate, and the fixed ring drives the negative magnet to rotate. When the negative magnet and the positive magnet are misaligned, the lifting support ring moves downward under the action of gravity. The lifting support ring pulls the electromagnetic spray gun through the pull rope. When the positive magnet and the negative magnet are aligned, the repulsive force between the positive magnet and the negative magnet pushes the lifting support ring upward, and the electromagnetic spray gun is reset. As the fixed ring rotates, the electromagnetic spray gun can swing back and forth. In this way, when the rotating rod and blades are mixing concrete, the diluted foaming agent can be evenly sprinkled on the concrete, so as to quickly complete the mixing of concrete and foaming agent and improve the preparation efficiency of foamed concrete slurry.

[0026] S4. When it is necessary to clean the inside of the mixing tank, the foamed concrete slurry is discharged through the discharge pipe for pouring. After the sliding plate loses the weight of the foamed concrete slurry, it moves upward and resets under the elastic force of the spring. The second contact plate separates from the first contact plate, the strong magnet is de-energized, and the iron nut ring falls under the gravity of the cleaning ring. The iron nut ring begins to engage with the threaded section. Then, the rotating rod rotates and can drive the iron nut ring to move downward. The downward movement of the cleaning ring can scrape off the foamed concrete slurry remaining on the inner wall of the mixing tank. In addition, when the U-shaped rod rotates one revolution, it can drive the rotating rod to rotate several revolutions through the cooperation of the rack and gear, the first synchronous pulley, the second synchronous pulley and the synchronous belt, so that the iron nut ring can move from the top of the threaded section to the bottom. Thus, when cleaning is performed, the U-shaped rod rotates back and forth half a revolution.

[0027] S5. Additionally, when the cleaning ring cleans the inner wall of the mixing tank, clean water is injected into the solution transfer ring through the second drain pipe. Thus, when the cleaning ring cleans the inner wall of the mixing tank, the electromagnetic spray gun can spray clean water into the mixing tank, which facilitates the cleaning of the inner wall of the cleaning ring. At the same time, the clean water sprayed by the electromagnetic spray gun can also rinse the blades.

[0028] In this invention, the bottom of the rotating ring in the solution is rotatably connected to multiple electromagnetic spray guns via a base. Each electromagnetic spray gun has a pull rope at its top, and the bottom of each pull rope is anchored to the same lifting and supporting ring. The top of the fixed ring is fixedly connected to multiple negative magnets, and the bottom of the lifting and supporting ring is fixedly connected to multiple positive magnets. When the negative and positive magnets are misaligned, the lifting and supporting ring moves downwards and pulls the electromagnetic spray guns. When the positive and negative magnets are aligned, the repulsive force between them pushes the lifting and supporting ring upwards, resetting the electromagnetic spray guns. Through the spraying structure, the electromagnetic spray guns can oscillate back and forth. When the rotating rod and blades mix concrete, the diluted foaming agent can be evenly sprayed onto the concrete, thus enabling rapid mixing of the concrete and the foaming agent.

[0029] In this invention, a cleaning ring is slidably connected to the inner wall of the mixing tank. The cleaning ring is connected to a rope via a connecting block. The top ends of the two ropes are anchored to the same iron nut ring. A strong magnet that cooperates with the iron nut ring is fixedly connected to the bottom of the fixing frame. The outer wall of the rotating rod is provided with a threaded section. The rotating rod is threadedly connected to the iron nut ring through the threaded section. The rotation of the rotating rod can drive the iron nut ring to move downward. Through the cleaning structure, the cleaning ring can be raised and lowered to scrape off the foamed concrete slurry remaining on the inner wall of the mixing tank, preventing the foamed concrete slurry remaining on the inner wall of the mixing tank from affecting the subsequent preparation of foamed concrete slurry.

[0030] In this invention, a sliding plate is slidably connected inside the mixing tank. The bottom of the sliding plate is fixedly connected to the bottom inner wall of the mixing tank by multiple springs. A second contact piece and a first contact piece are respectively fixed to the bottom of the sliding plate and the bottom inner wall of the mixing tank. When the sliding plate moves downward under the action of the weight of the concrete, the first and second contact pieces come into contact. The strong magnet generates an upward magnetic attraction force on the iron nut ring, and the iron nut ring disengages from the threaded section, which facilitates the mixing of concrete and foaming agent by rotating the rod. When the foamed concrete slurry in the mixing tank is discharged, the sliding plate returns to its original position, and the iron nut ring begins to engage with the threaded section, which facilitates the cleaning of the inner wall of the mixing tank later. Therefore, it is possible to complete the preparation of foamed concrete slurry and clean the inner wall of the mixing tank.

[0031] In this invention, the foaming agent dilution can be evenly sprayed onto the concrete being mixed through a spraying structure, thereby quickly completing the mixing of concrete and foaming agent and improving the preparation efficiency of foamed concrete slurry. In addition, the pressure of the concrete on the sliding plate can control the start and stop of the strong magnet, and the strong magnet can control the raising and lowering of the iron nut ring, thereby automatically cleaning the inner wall of the mixing tank after the concrete is discharged.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Example 1

[0043] Reference Figures 1-7 A vertical combined packing device, which is used in the field of combined packing equipment, includes a lower support 1, an upper support 2 fixed to the top of the lower support 1 by bolts, a mixing tank 11 fixed to the top of the lower support 1 by bolts, and a concrete tank 3 and two preparation tanks 4 fixed to the top of the upper support 2 by bolts.

[0044] Reference Figure 2 , Figure 3 and Figure 4The equipment also includes a mixing structure installed in the preparation tank 4 and the concrete tank 3 for preparing concrete and diluted foaming agent. The mixing structure includes a U-shaped rod 5 rotatably connected in the concrete tank 3. Multiple mixing blades 6 are bolted to the outer wall of the U-shaped rod 5. A connecting rod 7 is rotatably sleeved on the outer wall of the U-shaped rod 5. A rack 8 is rotatably connected to one end of the connecting rod 7, and one end of the rack 8 is sealed and slides through the concrete tank 3. Mixing rods 9 are rotatably connected in both preparation tanks 4. The tops of both mixing rods 9 extend to the top of the preparation tank 4. The two mixing rods 9 are connected by a belt and a leather belt. The system is connected by a pulley drive. One of the mixing rods 9 has a gear 10 fixed to its top by bolts, and the rack 8 meshes with the gear 10. The U-shaped rod 5 is driven by a motor to rotate. The U-shaped rod 5 mixes the cement and sandy soil in the concrete box 3 to form concrete. The U-shaped rod 5 and the connecting rod 7 work together to drive the rack 8 to rotate back and forth. The rack 8 drives the mixing rod 9 to rotate back and forth through the gear 10. The two mixing rods 9 are connected by a belt and a pulley drive. Thus, when the U-shaped rod 5 finishes mixing the concrete, it can simultaneously mix the foaming agent dilution liquid of different concentrations in the two preparation boxes 4.

[0045] Reference Figures 3-7 The equipment also includes a spraying structure installed inside the mixing tank 11, which is used to uniformly mix the diluted foaming agent with the concrete inside the mixing tank 11. The spraying structure includes a rotating rod 13 rotatably connected to the inner wall of the bottom of the mixing tank 11. The outer wall of the rotating rod 13 is provided with multiple blades 14. The top of the upper support 2 is fixedly connected to a fixing frame 15. The top of the rotating rod 13 rotates through the fixing frame 15 and is fixedly connected to a first synchronous wheel 16. The outer wall of one of the mixing rods 9 is fixed with a second synchronous wheel 17. The first synchronous wheel 16 and the second synchronous wheel 17 are connected by a synchronous belt 18. The bottom of the concrete box 3 is connected to the mixing tank 11 through an injection pipe 12. The rotating rod 13 is driven to rotate by the cooperation of the first synchronous wheel 16, the second synchronous wheel 17 and the synchronous belt 18. The rotating rod 13 can fully mix the concrete with the foaming agent entering the mixing tank 11 to prepare lightweight foamed concrete.

[0046] Reference Figures 3-7The spraying structure also includes a rectangular groove 19 set on the top of the mixing tank 11. A solution transfer ring 20 is fixedly connected inside the rectangular groove 19, and the top end of the rotating rod 13 passes through the solution transfer ring 20. Multiple electromagnetic spray guns 24 are rotatably connected to the bottom of the solution transfer ring 20 via a base. The multiple electromagnetic spray guns 24 are arranged in a ring around the rotating rod 13. Each of the multiple electromagnetic spray guns 24 has a pull rope 25 at its top. The bottom end of the multiple pull ropes 25 is anchored to the same lifting load-bearing ring 23. The lifting load-bearing ring 23 is sleeved on the outer wall of the rotating rod 13. A fixing ring 26 located below the lifting load-bearing ring 23 is fixed to the outer wall of the rotating rod 13. Multiple negative magnets 28 are fixedly connected to the top of the fixing ring 26, and multiple positive magnets 27 are fixedly connected to the bottom of the lifting load-bearing ring 23. In conjunction with the negative magnet 28, the bottoms of both preparation boxes 4 are connected to the rotating ring 20 in the solution through the first drain pipe 21. The rotating rod 13 drives the fixed ring 26 and the negative magnet 28 to rotate. When the negative magnet 28 and the positive magnet 27 are misaligned, the lifting and supporting ring 23 moves down, pulling the electromagnetic spray gun 24. When the positive magnet 27 and the negative magnet 28 are aligned, the repulsive force between the positive magnet 27 and the negative magnet 28 pushes the lifting and supporting ring 23 up, and the electromagnetic spray gun 24 is reset. With the rotation of the fixed ring 26, the electromagnetic spray gun 24 can swing back and forth. Thus, when the rotating rod 13 and the blade 14 are mixing concrete, the diluted foaming agent can be evenly sprinkled on the concrete, thereby quickly completing the mixing of concrete and foaming agent and improving the preparation efficiency of foamed concrete slurry.

[0047] Reference Figure 6 and Figure 7 The top of the rotating ring 20 in the solution is provided with a second drain pipe 22, which is connected to an external water source. The bottom of the rotating ring 20 in the solution is fixed with multiple sliding rods 41 by bolts, and the bottom end of the sliding rods 41 slides into the lifting load-bearing ring 23. The outer wall of the rotating rod 13 is fixed with a limit ring 40, which is located between the fixed ring 26 and the lifting load-bearing ring 23. The limit ring 40 can limit the upper part of the lifting load-bearing ring 23, and the sliding rods 41 can make the lifting load-bearing ring 23 slide vertically. In addition, when cleaning the inside of the mixing tank 11, the second drain pipe 22 ensures the cleanliness of the inside of the mixing tank 11.

[0048] Reference Figures 3-5The device also includes a cleaning structure installed inside the mixing tank 11 for cleaning the interior of the mixing tank 11. The cleaning structure includes a cleaning ring 34 slidably connected to the inner wall of the mixing tank 11. Connecting blocks 33 are fixedly connected to the inner walls of the two adjacent sides of the cleaning ring 34. Ropes 32 are anchored to the top of the two connecting blocks 33. The same iron nut ring 30 is anchored to the top of the two ropes 32. A strong magnet 31 that cooperates with the iron nut ring 30 is fixedly connected to the bottom of the fixing frame 15. The outer wall of the rotating rod 13 is provided with a threaded section 29. The rotating rod 13 is threadedly connected to the iron nut ring 30 through the threaded section 29. The rotation of the rotating rod 13 can drive the iron nut ring 30 to move downward. The downward movement of the cleaning ring 34 can scrape off the foamed concrete slurry remaining on the inner wall of the mixing tank 11, preventing the foamed concrete slurry remaining on the inner wall of the mixing tank 11 from affecting the subsequent preparation of foamed concrete slurry.

[0049] Reference Figure 5 The cleaning structure also includes a sliding plate 35 slidably connected within the mixing tank 11. Multiple springs 36 are fixedly connected to the bottom inner wall of the mixing tank 11, with the tops of each spring 36 fixedly connected to the bottom of the sliding plate 35. A first contact piece 37 is bolted to the bottom inner wall of the mixing tank 11, and a second contact piece 38, which mates with the first contact piece 37, is bolted to the bottom of the sliding plate 35. The second contact piece 38 is electrically connected to a strong magnet 31. The bottom end of the rotating rod 13 passes through the sliding plate 35. The sliding plate 35 moves downwards under the influence of the concrete's gravity. When the first contact piece 37 and the second contact piece 38 come into contact, the strong magnet 31 generates an upward magnetic attraction force on the iron nut ring 30, thereby disengaging the iron nut ring 30 from the threaded section 29, which facilitates the mixing of concrete and foaming agent by rotating the rod 13. After the foamed concrete slurry in the mixing tank 11 is discharged, the sliding plate 35 returns to its original position, and the iron nut ring 30 begins to engage with the threaded section 29, which facilitates the cleaning of the inner wall of the mixing tank 11 later. Therefore, it is possible to complete the preparation of foamed concrete slurry and clean the inner wall of the mixing tank 11.

[0050] Reference Figure 5 The rectangular groove 19 is provided with two guide wheels 39, which are used to guide the rope 32. The sliding plate 35 is fixedly connected to the discharge pipe 42, and the top of the discharge pipe 42 is flush with the top of the sliding plate 35. The bottom end of the discharge pipe 42 slides through the bottom inner wall of the mixing tank 11.

[0051] Example 2

[0052] refer to Figure 8An improvement based on Example 1 is made as follows: a storage tube 43 is fixed to one side of each of the two preparation boxes 4 by bolts, a scale 46 is fixed to one side of the storage tube 43 by bolts, a liquid guide tube 44 is provided at the bottom of the storage tube 43 and is connected to the preparation box 4, and a valve 45 is provided on the outer wall of the liquid guide tube 44; the capacity of the foaming agent in the storage tube 43 can be clearly determined by the scale 46, so that foaming agent dilutions of different concentrations can be prepared more conveniently.

[0053] A method of using a vertical combined packing device includes the following steps:

[0054] S1. Cement and sandy soil are put into concrete box 3. Then, equal amounts of water are injected into two preparation boxes 4. Foaming agent of different volumes is injected into two storage tubes 43 respectively. The volume of foaming agent in storage tube 43 can be determined by scale 46. Thus, foaming agent dilutions of different concentrations can be obtained in the two preparation boxes 4.

[0055] S2. The U-shaped rod 5 is driven by a motor to rotate. The U-shaped rod 5 mixes the cement and sandy soil in the concrete box 3 to form concrete. The U-shaped rod 5 and the connecting rod 7 work together to drive the rack 8 to rotate back and forth. The rack 8 drives the mixing rod 9 to rotate back and forth through the gear 10. The two mixing rods 9 are connected by a belt and a pulley. Thus, when the U-shaped rod 5 finishes mixing the concrete, it can simultaneously mix the foaming agent dilution liquid of different concentrations in the two preparation boxes 4.

[0056] S3. Concrete from concrete box 3 is injected into mixing tank 11 through injection pipe 12. Foaming agent dilution from one of preparation tanks 4 is injected into solution rotating ring 20 through first drainage pipe 21. Sliding plate 35 moves downward under the force of concrete gravity, spring 36 is compressed, first contact piece 37 and second contact piece 38 come into contact, strong magnet 31 generates an upward magnetic attraction force on iron nut ring 30, and iron nut ring 30 disengages from threaded section 29. At this time, the rotation rod 13 is driven to rotate through the cooperation of first synchronous pulley 16, second synchronous pulley 17 and synchronous belt 18. Rotating rod 13 drives fixed ring 26 to rotate, and fixed ring 26 drives negative magnet 26 to rotate. When the iron 28 rotates, and the negative magnet 28 and the positive magnet 27 are misaligned, the lifting support ring 23 moves downward under the action of gravity. The lifting support ring 23 pulls the electromagnetic spray gun 24 through the pull rope 25. When the positive magnet 27 and the negative magnet 28 are aligned, the repulsive force between the positive magnet 27 and the negative magnet 28 pushes the lifting support ring 23 upward, and the electromagnetic spray gun 24 is reset. As the fixed ring 26 rotates, the electromagnetic spray gun 24 can swing back and forth. Thus, when the rotating rod 13 and the blade 14 are mixing concrete, the diluted foaming agent can be evenly sprinkled on the concrete, thereby quickly completing the mixing of concrete and foaming agent and improving the preparation efficiency of foamed concrete slurry.

[0057] S4. When it is necessary to clean the inside of the mixing tank 11, the material is discharged through the discharge pipe 42 for pouring. After the sliding plate 35 loses the weight of the foamed concrete slurry, it moves upward and resets under the elastic force of the spring 36. The second contact piece 38 separates from the first contact piece 37, the strong magnet 31 is de-energized, and the iron nut ring 30 falls under the gravity of the cleaning ring 34. The iron nut ring 30 begins to engage with the threaded section 29. Then, the rotating rod 13 rotates and can drive the iron nut ring 30 to move downward. The downward movement of the cleaning ring 34 can scrape off the foamed concrete slurry remaining on the inner wall of the mixing tank 11. In addition, when the U-shaped rod 5 rotates one revolution, the engagement of the rack 8 with the gear 10, the first synchronous pulley 16, the second synchronous pulley 17 and the synchronous belt 18 can drive the rotating rod 13 to rotate several revolutions, which can move the iron nut ring 30 from the top of the threaded section 29 to the bottom. Thus, when cleaning is performed, the U-shaped rod 5 rotates back and forth half a revolution.

[0058] S5. Additionally, when the cleaning ring 34 cleans the inner wall of the mixing tank 11, clean water is injected into the solution transfer ring 20 through the second drain pipe 22. Thus, when the cleaning ring 34 cleans the inner wall of the mixing tank 11, the electromagnetic spray gun 24 can spray clean water into the mixing tank 11, which facilitates the cleaning of the inner wall of the cleaning ring 34. At the same time, the clean water sprayed by the electromagnetic spray gun 24 can also rinse the blades 14.

[0059] However, as is well known to those skilled in the art, the working principle and wiring method of the electromagnetic spray gun 24 are commonplace and are all conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
