Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, and in particular to an integrated continuous mixing device. Background Technology

[0002] Mixer trucks are often used in fields such as emergency repairs in transportation engineering. These mixer trucks typically consist of a screw conveyor and a twin-shaft mixing device, forming a mixing combination machine. Through physical connection, control logic integration, or functional superposition, different mixing equipment or mixing components are combined into a system. Through the synergistic effect between the equipment, complex mixing needs that cannot be met by a single device are solved, achieving a more efficient and complex mixing process. Its core lies in functional complementarity and system optimization.

[0003] Phosphate cement concrete possesses excellent mechanical properties and durability, making it highly suitable for rapid repair projects. Currently, phosphate concrete is typically mixed using intermittent mixing equipment, which allows for controllable mixing quality but results in low mixing efficiency. Continuous mixing equipment offers high mixing efficiency and integration, but its batching accuracy is lower. Furthermore, most continuous mixing equipment on the market is designed for mixing traditional cement concrete systems, such as rapid-hardening silicate cement concrete and rapid-hardening sulfoaluminate cement concrete. When using continuous mixing equipment to mix phosphate concrete, the significant differences in mixing methods between phosphate cement concrete and traditional cement concrete, coupled with its sensitivity to water content, lead to greater relative measurement deviations in the components and poorer concrete mix quality. This makes it difficult to mix concrete according to the mix design requirements for phosphate concrete. Therefore, it is essential to develop equipment suitable for mixing phosphate concrete.

[0004] Meanwhile, during the concrete production and mixing process, the concrete is mixed and stirred in the twin-shaft mixing unit inside the mixer truck. Concrete has adhesive properties, so after the mixing and production is completed, the concrete will adhere to the inner wall, shaft, and blades of the twin-shaft mixing unit. Therefore, after construction, it is often necessary for construction personnel to manually clean and scrape off the concrete adhering to the surface in time to prevent it from solidifying and causing the twin-shaft mixing unit to malfunction. However, whether it is manual scraping or manual flushing with pipes, the cleaning efficiency is low, the operation is inconvenient, the process is slow, and it requires a certain amount of labor.

[0005] Therefore, an integrated continuous mixing device is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated continuous mixing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an integrated continuous mixing device, comprising a vehicle body, wherein a mixing device, a continuous conveying device, a water supply device, a storage silo, a water tank, a control system, and other components are fixedly installed in the vehicle body; the mixing device is provided with a twin-shaft mixing chamber; the continuous conveying device is a screw conveyor connecting the storage silo and the mixing device; the water supply device connects the water tank and the mixing device; a screw unloader is provided at the bottom of the storage silo; the control system includes a repair material stepless speed regulation system, a water flow control system, and a monitoring system, all integrated into a control panel; the twin-shaft mixing chamber is provided with a discharge port; the twin-shaft mixing chamber is provided with a scraper assembly for removing concrete adhering to the twin-shaft mixing chamber; the scraper assembly includes a scraper slidably connected to the mixing device, and a conical plate is fixedly connected to the scraper; a sealing plate is slidably connected to the twin-shaft mixing chamber.

[0008] Preferably, the screw conveyor and screw unloader control the conveying rate of the repair material through stepless speed regulation, and control the water flow rate through a flow meter. The conveying rates of each device are in the following order: mixing device ≥ screw conveyor ≥ screw unloader.

[0009] Preferably, an electric slide rail is fixedly installed on the dual-shaft mixing tank, the scraper is fixedly connected to the slider in the electric slide rail, and the scraper is adapted to fit the inner wall of the dual-shaft mixing tank.

[0010] Preferably, a push plate is fixedly connected to the sealing plate, and the push plate is slidably connected in the twin-shaft mixing tank. A tension spring is fixedly connected between the push plate and the twin-shaft mixing tank. The movement of the scraper can push the push plate to open the sealing plate, thereby facilitating the discharge of the scraped concrete from the twin-shaft mixing tank.

[0011] Preferably, the scraper is provided with a flushing assembly for flushing and removing concrete adhering to the rotating shaft and blades. The flushing assembly includes a first pipe, a second pipe and a third pipe slidably connected in the scraper, and a plurality of nozzles are fixedly installed on the first pipe, the second pipe and the third pipe.

[0012] Preferably, a connecting hose is fixedly connected between the second pipe, the third pipe, and the first pipe, and a one-way valve is fixedly installed in the nozzle.

[0013] Preferably, a water inlet pipe is fixedly connected to the first pipe, and a baffle is fixedly installed on the scraper.

[0014] Preferably, the scraper is provided with a pushing component, which is used for the first pipe, the second pipe and the third pipe to slide in the scraper, increasing the spray range of the nozzle spraying water outward. The pushing component includes a push block fixedly connected to the first pipe, and the water inlet pipe is slidably connected to the push block. An installation frame is fixedly installed on the dual-shaft mixing tank, and a number of stops are fixedly connected to the installation frame, and the stops are inclined in a manner that matches the push block.

[0015] Preferably, a transmission rod is provided between the second pipe, the first pipe, and the third pipe. The transmission rod includes an arc-shaped tube, and a first push rod and a second push rod are slidably connected to both ends of the arc-shaped tube.

[0016] Preferably, the first push rod is fixedly connected to the first pipe, the second push rod is fixedly connected to the second pipe, the arc pipe is filled with hydraulic oil, and the retraction and movement of the first push rod can push the second push rod to extend by pushing the hydraulic oil. A spring is fixedly connected between the third pipe and the scraper.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention is not only applicable to the rapid repair of traditional cement concrete, but also to the continuous mixing of phosphate cement concrete, which greatly improves the efficiency of on-site repair, has good construction mobility, can accurately control the amount of water in the concrete, and has high concrete mixing quality. It is especially suitable for emergency repair projects with large construction volume, short construction time, and high repair quality requirements.

[0019] 2. This invention, by setting up a scraping assembly, enables the mixing device to move the scraper and cone plate in the twin-shaft mixing tank under the drive of the electric slide rail after the mixing production is completed. The friction between the cone plate and the scraper scrapes off the concrete adhering to the inner wall of the twin-shaft mixing tank and pushes it to the discharge port for discharge. At the same time, the scraper can also scrape repeatedly when it moves in the opposite direction to ensure that the inner wall of the twin-shaft mixing tank is clean. The concrete is pushed to the sealing plate, and the scraper pushes the push plate to open the sealing plate, so that the concrete can be discharged in time.

[0020] 3. This invention, by setting up a flushing component, allows the scraper to remove concrete from the inner wall of the twin-shaft mixing tank while the water pipe is connected to an external water source. This fills the first, second, and third pipes with water, and under water pressure, opens the one-way valve, allowing flushing water to be sprayed out through the nozzles. This flushes the rotating shaft and blades in the twin-shaft mixing tank, cleaning the concrete adhering to the shaft and blades and removing it from the mixing tank. The concrete is then discharged outwards under the pushing action of the scraper. The entire device, with the scraping component and the flushing component working together, automatically removes the concrete adhering to the mixing device, eliminating the need for manual cleaning, improving cleaning efficiency, and reducing labor intensity.

[0021] 4. This invention, by setting up a pushing component, enables the scraper and nozzle to clean the concrete in the dual-shaft mixing tank. During the process, the movement of the scraper causes the push block and the stop block to work together, causing the first pipe to move downwards in the scraper. Through the action of the transmission rod, the first pipe pushes the second pipe to move, and the second pipe pushes the third pipe to move. When the push block disengages from the stop block, the first, second, and third pipes move and reset, thus forming a cyclical movement. This causes the direction and angle of the water flow sprayed from the nozzle to continuously change, forming a multi-directional impact force, which makes the rinsing coverage larger, eliminates residual dead corners, reduces rinsing blind spots, and enhances the rinsing effect.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0036] like Figures 1 to 10As shown in the figure, a specific embodiment of the present invention provides an integrated continuous mixing device, including a vehicle body 1. A mixing device 2, a continuous conveying device, a water supply device, a storage silo, a water tank, and a control system are fixedly installed in the vehicle body 1. The mixing device 2 is equipped with a dual-shaft mixing chamber 3. The continuous conveying device is a screw conveyor connected to the storage silo and the mixing device 2. The screw conveyor controls the conveying rate of the phosphate repair material through stepless speed regulation. The water supply device is connected to the water tank and the mixing device 2, and the water volume is controlled by a flow meter. The storage silo and the water tank are used to store the repair material and water, respectively. A screw conveyor is installed at the bottom of the silo, and the screw conveyor can also be steplessly speed-regulated to control the flow rate of repair material from the storage silo into the screw conveyor. The control system includes a steplessly speed-regulating system for repair material, a water flow control system, and a monitoring system. The control system is integrated into a control panel. The monitoring system is used to observe the status of each key link. To avoid phenomena such as material blockage or machine failure during the mixing process, the conveying rates of each device are in the following order: mixing device ≥ screw conveyor ≥ screw conveyor. The nominal maximum particle size of coarse aggregate in the repair material is not greater than 19mm, which meets the requirements of the standard MH / T 5084-2025 "Technical Specification for Maintenance of Cement Concrete Pavement of Civil Airports".

[0037] The prepared phosphate cement concrete is loaded into the storage silo, and sufficient tap water is added to the water tank. The mixing device 2, the continuous conveying device, and the screw unloader are turned on in sequence. The stepless speed control switch is adjusted so that the conveying efficiency of the continuous conveying device for the repair material reaches 70% to 90% of the maximum mixing efficiency of the mixing device. Preferably, the conveying efficiency of the continuous conveying device is 80% to 85% of the maximum mixing efficiency of the mixing device. The weight of the repair material discharged from the mixing device within a specified time is continuously recorded, and the average production efficiency of the repair material per minute is calculated. The water supply flow rate is set to 5% to 6% of the total weight of the repair material using a flow meter, so that the repair material and water are accurately, continuously, and evenly supplied to the mixing device at the same time. The water outlet on the mixing device is set in the form of a shower head to facilitate the rapid and even contact of water with the repair material.

[0038] The phosphate cement concrete mixed using the integrated continuous mixing equipment proposed in this invention exhibits good workability, cohesiveness, and homogeneity. The comprehensive performance of the concrete mixed using the integrated continuous mixing equipment proposed in this invention was tested in accordance with JTG 3420-2020 "Test Procedures for Cement and Cement Concrete in Highway Engineering". The test results are shown in Table 1.

[0039] Table 1 Performance of Phosphate Cement Concrete

[0040]

[0041] As shown in Table 1, the phosphate concrete mixture mixed using the mixing equipment proposed in this invention exhibits good workability, with a slump of 210 mm and a slump spread of 495 mm. The tested 1-hour flexural and compressive strengths are 4.1 MPa and 35.2 MPa, respectively, meeting the requirements for rapid repair. The 28-day flexural and compressive strengths are 7.9 MPa and 66.3 MPa, respectively, showing stable strength growth in the later stages and excellent mechanical properties. The bond-flexural strengths at 3 hours, 3 days, and 28 days are 3.9 MPa, 5.5 MPa, and 6.8 MPa, respectively, indicating high concrete bond strength. The concrete also demonstrates excellent durability indicators such as freeze-thaw resistance, salt-freeze resistance, abrasion resistance, and shrinkage rate, meeting the relevant requirements of MH / T 5084-2025 "Technical Specification for Maintenance of Cement Concrete Pavement in Civil Airports".

[0042] like Figures 1 to 10 As shown, the twin-shaft mixing tank 3 is equipped with a discharge port 4 and a scraper assembly. The scraper assembly is used to remove concrete adhering to the twin-shaft mixing tank 3. During the operation of the mixing device 2, as the rotating shaft and blades in the twin-shaft mixing tank 3 continuously rotate, the concrete inside is mixed. Some concrete will adhere to the inner wall of the twin-shaft mixing tank 3, the rotating shaft, and the blades. When the mixing device 2 stops working, it needs to be removed in time to prevent it from solidifying and increasing the difficulty of processing, thus affecting the normal use of the mixing device 2. The scraper assembly can replace manual operation and automatically process and remove the concrete adhering to the inner wall of the twin-shaft mixing tank 3, and discharge the processed concrete from the twin-shaft mixing tank 3 in time, thereby improving cleaning efficiency and reducing labor intensity. The scraper assembly includes a scraper 5 that is slidably connected to the mixing device 2, and a cone plate 6 is fixedly connected to the scraper 5. A sealing plate 7 is slidably connected to the twin-shaft mixing tank 3.

[0043] The scraper 5 is equipped with a flushing component, which is used to flush away the concrete adhering to the rotating shaft and blades. By setting the flushing component, the concrete adhering to the rotating shaft and blades in the twin-shaft mixing tank 3 can be cleaned in time. After flushing, the concrete falls into the twin-shaft mixing tank 3 and is discharged from the twin-shaft mixing tank 3 in time by the scraping component. The flushing component includes a first pipe 10, a second pipe 11 and a third pipe 12 slidably connected in the scraper 5, and several nozzles 13 are fixedly installed on the first pipe 10, the second pipe 11 and the third pipe 12.

[0044] The scraper 5 is equipped with a pushing component, which is used for the first pipe 10, the second pipe 11 and the third pipe 12 to slide in the scraper 5, increasing the spray range of the nozzle 13. By setting the pushing component, the nozzle 13 can generate dynamic cyclic movement, so that the water flow direction and angle are constantly changing, forming a multi-directional impact force, making its rinsing coverage larger, eliminating residual dead corners, reducing rinsing blind spots, and thus enhancing the rinsing effect. The pushing component includes a push block 18 fixedly connected to the first pipe 10, and the water inlet pipe 16 is slidably connected to the push block 18. A mounting frame 19 is fixedly installed on the dual-shaft mixing tank 3, and several baffles 20 are fixedly connected to the mounting frame 19, and the baffles 20 are set in an inclined shape that is adapted to the push block 18.

[0045] like Figures 1 to 6 As shown, specifically, an electric slide rail 8 is fixedly installed on the twin-shaft mixing tank 3. The scraper 5 is fixedly connected to the slider in the electric slide rail 8. The scraper 5 fits snugly against the inner wall of the twin-shaft mixing tank 3. A push plate 9 is fixedly connected to the sealing plate 7, and the push plate 9 is slidably connected in the twin-shaft mixing tank 3. A tension spring 901 is fixedly connected between the push plate 9 and the twin-shaft mixing tank 3. The movement of the scraper 5 can push the push plate 9 to open the sealing plate 7, thereby facilitating the discharge of the scraped concrete from the twin-shaft mixing tank 3. After the mixing device 2 completes the mixing process, it cleans the residual adhering concrete. During the removal process, the electric slide rails 8 installed on both sides of the twin-shaft mixing tank 3 are activated to drive the scraper 5 to move. The electric slide rails 8 on both sides move synchronously, thereby jointly driving the scraper 5 and the cone plate 6 on the scraper 5 to move friably in the twin-shaft mixing tank 3. As the scraper 5 moves to the discharge port 4, the scraper 5 pushes the cone plate 6 to scrape off the concrete adhering to the inner wall of the twin-shaft mixing tank 3, thereby scraping off the concrete adhering to the inner wall of the twin-shaft mixing tank 3, causing it to fall to the bottom of the inner cavity of the twin-shaft mixing tank 3, and being pushed to the discharge port 4 for discharge under the action of the scraper 5.

[0046] After the scraper 5 moves to the discharge port 4 and discharges the concrete, it moves in the opposite direction under the action of the electric slide rail 8. During the reverse movement, the scraper 5 pushes the cone plate 6 on the other side to process the concrete again, ensuring that the concrete adhering to the inner wall of the twin-shaft mixing tank 3 is cleaned up. At the same time, the concrete is pushed onto the sealing plate 7. When the scraper 5 moves to the sealing plate 7, the scraper 5 can push the push plate 9 to pull the tension spring 901 to extend and generate a reaction force. After the push plate 9 moves, it can pull the sealing plate 7 to move, so that the sealing plate 7 gradually opens. As the sealing plate 7 slides on the twin-shaft mixing tank 3, it gradually opens. The concrete pushed by the scraper 5 is discharged downwards as the sealing plate 7 slides open, thus exiting the inner cavity of the twin-shaft mixing tank 3. Therefore, as the scraper 5 moves back and forth in the twin-shaft mixing tank 3, it can ensure that the scraper 5 scrapes off and discharges the concrete adhering to its inner wall. When the scraper 5 disengages from the push plate 9, the push plate 9 moves and resets under the action of the tension spring 901, so that the sealing plate 7 closes. The closure of the sealing plate 7 can ensure that when the mixing device 2 is in normal use, the material in the mixing process will not be discharged from the twin-shaft mixing tank 3, and the material can only be discharged through the discharge port 4.

[0047] like Figures 3 to 10As shown, specifically, a connecting hose 14 is fixedly connected between the second pipe 11, the third pipe 12, and the first pipe 10. A one-way valve 15 is fixedly installed in the nozzle 13. A water inlet pipe 16 is fixedly connected to the first pipe 10. A baffle 17 is fixedly installed on the scraper 5. During the scraping process as the scraper 5 moves in the dual-shaft mixing tank 3, the water inlet pipe 16 is connected to an external pipe. Water is continuously supplied to the water inlet pipe 16 by a high-pressure water pump. A water storage tank is provided in the vehicle body 1. This is an essential structural device for the operation of the entire combined machine and is existing technology. This system can promptly provide the water needed for washing concrete. After the water inlet pipe 16 is connected to the water source, external water is continuously injected into the water inlet pipe 16 and enters the first pipe 10. Through the connection hose 14, the water gradually enters the second pipe 11 and the third pipe 12. As water is continuously injected, the water pressure in the first pipe 10, the second pipe 11, and the third pipe 12 gradually increases. Under this pressure, the one-way valve 15 in the nozzle 13 opens, allowing water in the first pipe 10, the second pipe 11, and the third pipe 12 to pass through the one-way valve. After 15 seconds, the water is sprayed outward through nozzle 13. The water sprayed from nozzles 13 on the first pipe 10, second pipe 11, and third pipe 12 can wash the rotating shaft and blades on the rotating shaft in the twin-shaft mixing tank 3. While washing, the mixing device 2 is activated so that the rotating shaft and blades can rotate slowly, thus coordinating with the sprayed water for all-round washing. The baffle 17 is set to prevent some of the water sprayed from the nozzles 13 on the second pipe 11 from spraying upward without contacting the rotating shaft and blades. The baffle 17 can block the water from spraying upward. Spraying water to a distant location can have adverse effects. However, after the spraying water washes away the concrete adhering to the shaft and blades, the concrete will fall into the twin-shaft mixing tank 3 and be pushed out of the twin-shaft mixing tank 3 by the cyclical movement of the scraper 5. When spraying stops and no more water is added to the tank, the one-way valve 15 closes. The closure of the one-way valve 15 can prevent mud and sand in the twin-shaft mixing tank 3 from entering the first pipe 10, the second pipe 11 and the third pipe 12 through the nozzle 13, thereby avoiding clogging of the nozzle 13.

[0048] like Figures 6 to 10As shown, specifically, transmission rods are provided between the second pipe 11, the first pipe 10, and the third pipe 12. Each transmission rod includes an arc-shaped tube 21, with a first push rod 22 and a second push rod 23 slidably connected to both ends of the arc-shaped tube 21. The first push rod 22 is fixedly connected to the first pipe 10, and the second push rod 23 is fixedly connected to the second pipe 11. Hydraulic oil is provided inside the arc-shaped tube 21. The retraction and movement of the first push rod 22 can push the second push rod 23 to extend by pushing the hydraulic oil. A spring 24 is fixedly connected between the third pipe 12 and the scraper 5. Simultaneously, during the process of the nozzle 13 spraying water for rinsing and the scraper 5 moving, as the scraper 5 moves, it drives the push block 18 to move. During this movement, the push block 18 gradually contacts and adheres to the stop block 20 on the mounting frame 19. Because the stop block 20 and the push block 18 are set in a matching inclined shape, the stop block 20... Under the action of the force, the push block 18 moves downward, pushing the first pipe 10 downward. The downward movement of the first pipe 10 pushes the first push rod 22 to move in the arc pipe 21. The first push rod 22 pushes the second push rod 23 to slide out of the arc pipe 21 by pushing the hydraulic oil. Thus, the second push rod 23 pushes the second pipe 11 to move in the scraper 5. Here, the principle of the transmission rod is that the movement of the first push rod 22 uses the hydraulic oil in the arc pipe 21 as a medium to push the second push rod 23 to move. Conversely, the second push rod 23 can also push the hydraulic oil to push the first push rod 22 to move. Therefore, the movement of the first pipe 10 can push the second pipe 11 to move through the transmission rod. The movement of the second pipe 11 can also push the third pipe 12 to move through the transmission rod at the other end. The upward movement of the third pipe 12 causes the spring 24 to contract and generate a reaction force.

[0049] When the push block 18 disengages from the stop block 20 during its movement, it is no longer subjected to the pressure of the stop block 20. This allows the third pipe 12 to move downwards under the reaction force of the spring 24. As the third pipe 12 moves downwards, it can push the second pipe 11 to move in the opposite direction via the transmission rod. The reverse movement of the second pipe 11 can also push the first pipe 10 to move upwards via the transmission rod. Therefore, as the push block 18 moves and continuously contacts and disengages from the stop block 20, the first pipe 10, the second pipe 11, and the third pipe 12 can continuously circulate back and forth in the scraper 5. This causes the nozzle 13 to continuously circulate, and the direction and angle of the flushing water sprayed from the nozzle 13 continuously change, forming a multi-directional impact force. This makes the flushing coverage larger, eliminates residual dead corners, reduces flushing blind spots, and enhances the flushing effect. During the movement of the scraper 5, it also achieves the flushing of the blades in the dual-shaft mixing tank 3, allowing the concrete adhering to its surface to be better washed away.
