Description
Technical Field
[0001] This invention relates to the field of batching plant technology, specifically to a high-speed concrete batching equipment with temperature control function. Background Technology
[0002] Mixing plants are subdivided into categories such as stabilized soil mixing plants, water-stabilized soil mixing plants, asphalt mixing plants, and concrete mixing plants. Stabilized soil mixing plants are divided into mobile and stationary types. Mobile mixing plants have tires on each silo, allowing for easy and flexible relocation, but have a lower production capacity. Stationary stabilized soil mixing plants require a concrete foundation to fix the equipment in place, and have a higher production capacity. Stabilized soil mixing plants are specifically used for mixing stabilized soil and aggregates, mainly mixing binders such as lime, cement, and fly ash with soil, gravel, or other aggregates.
[0003] The heat of hydration of cement refers to the exothermic reaction that occurs when cement and water react. The heat continuously released during the hardening process of cement is called the heat of hydration. Since the batching plant processes a large amount of concrete at a time, the heat inside the concrete cannot be directly dissipated through the thick concrete layer after water is added. A large amount of heat accumulates inside the concrete, affecting the quality of the concrete after processing. Summary of the Invention
[0004] The purpose of this invention is to provide a high-speed concrete mixing equipment with temperature control function to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high-speed concrete mixing equipment with temperature control function, comprising a shell, on which a drive motor and a main shaft are installed. A compensating rod is provided at the connection between the rotating shaft and the drive motor. The compensating rod is slidably connected to the rotating shaft. The compensating rod realizes stable transmission of the drive motor during the jumping of the rotating shaft. The main shaft is hollow and passes through the upper end cover of the shell. The shell is provided with two tripods. A ring plate is installed on the outer side of the two tripods. A plurality of atomizing nozzles are provided on the ring plate. The atomizing nozzles are distributed in a ring on the ring plate. A plurality of stirring blades are provided on the lower outer wall of the main shaft. The stirring blades are distributed in a ring on the outer side of the main shaft and are set at different heights on the main shaft. Both the ring plate and the stirring blades are hollow. The main shaft is provided with several partitions, which divide the main shaft into several spaces. Each space is connected to a single stirring blade. The upper end of each space is connected to a ring plate. A drive rod is installed below the partition. The outer side of the housing is provided with a feed pipe, a discharge pipe and a water pipe. A water pump and a water inlet are installed on the water pipe, and the water pipe is connected to the main shaft and the ring plate.
[0006] Furthermore, the main shaft consists of a fixed shaft and a rotating shaft, which are respectively connected to the outer casing and the drive motor. The fixed shaft and the rotating shaft are sleeved together and connected by a drive rod. Both the fixed shaft and the rotating shaft are provided with toothed blocks at their connection points. The upper end of the drive rod is connected to a partition. When the drive rod controls the fixed shaft and the rotating shaft to be in contact with each other, and the drive rod is in its shortest state, the upper end of the rotating shaft is connected to the output shaft of the drive motor. During operation, the drive motor drives the rotating shaft to rotate synchronously. At the same time, toothed blocks are provided on adjacent sides of both the fixed shaft and the rotating shaft. The lower end of the fixed shaft is connected to the outer casing. With the cooperation of the drive motor and the toothed blocks, the rotating shaft reciprocates relative to the fixed shaft. The reciprocating motion of the rotating shaft results in a vibration effect on the stirring blades. The bends of the toothed blocks are provided with arc-shaped transitions, and the toothed blocks are made of highly wear-resistant material.
[0007] Furthermore, the stirring blade is composed of two staggered hollow plates, with a labyrinthine channel inside. A drive assembly is positioned between the two hollow plates, connected to a partition. Several water outlets are located at the lower end of each hollow plate, and several vertical arcuate strips are provided on the hollow plate. The stirring blade is connected to a rotating shaft, which drives the stirring blade to rotate within the outer casing during operation, stirring the raw materials inside. Since both the main shaft and the stirring blade are hollow structures, and the stirring blade has a labyrinthine channel inside, the water inlet pipe... Water is introduced into the channels inside the main shaft and mixing blades via water pipes. Simultaneously, a water pump circulates the water within the main shaft and mixing blades. As the water moves through the labyrinthine channels inside the mixing blades, it absorbs heat from the concrete, thus cooling the concrete during mixing. The surface of the mixing blades is equipped with several vertical arc strips to further enhance the mixing effect. A heat dissipation device is installed on the water pipes. The water flow, propelled by the water pump, passes through the heat dissipation device, facilitating the rapid release of the heat carried by the water.
[0008] Furthermore, a rack is provided on one side of the partition, and the drive assembly includes a connecting shaft provided on one side of the rack. The connecting shaft meshes with the rack, and a bushing is sleeved at the end of the connecting shaft. The bushing is connected to the hollow plate, and the connecting shaft and bushing are threaded together. The partition is connected to a drive rod, which is used to push the partition to rise and fall. The partition is slidably connected to the rotating shaft. During the period when the drive rod pushes the partition to rise and fall relative to the rotating shaft, the connecting shaft slides relative to the rotating shaft. Since the partition is meshed with the connecting shaft through the rack, and since the stirring blade is composed of two horizontally distributed and meshing hollow plates, the hollow plate closer to the rotating shaft is connected to the rotating shaft through the bushing, and the hollow plate farther from the rotating shaft is connected to the partition through the connecting shaft and bushing. During the rise and fall of the partition, the connecting shaft rotates around the bushing. The connecting shaft and bushing are threaded together. The two hollow plates are separated by the bushing and the rotating connecting shaft. Since the surface of the hollow plate is provided with several vertical arc strips, each area on a single arc strip... The staggered arrangement of the two hollow plates on the mixing blades causes the concrete adhering to the surface of the mixing blades to detach. When the drive rod is in its shortest state, the two hollow plates on the mixing blades are separated, and the concrete inside the outer shell has been completely discharged. The outer shell is in a cleaning state, and the width of the mixing blades increases after the hollow plates are separated. The side of the mixing blades is in contact with the inner wall of the outer shell. At this time, the drive motor rotates, and the rotating shaft drives the mixing blades to clean the inner wall of the outer shell. The bushing is fixedly connected to the rotating shaft, and the bushing is connected to the hollow plate near the rotating shaft through a bearing. The connecting shaft is fixedly connected to the hollow plate away from the rotating shaft. When the connecting shaft rotates, the connecting shaft, in conjunction with the bushing, causes the hollow plates to separate from each other, and the hollow plate away from the rotating shaft drives the mixing blades to rotate as a whole. When the drive rod is in its shortest state, the mixing blades are in a vertical state, and several water outlets are opened at the lower end of the hollow plates. When the hollow plates are staggered, the water outlets below the two hollow plates overlap, and some water inside the mixing blades is directly discharged through the water outlets.
[0009] Furthermore, the number of atomizing nozzles is odd, and an adjustment component is provided at the connection between the atomizing nozzle and the ring plate. The adjustment component is used to change the length of the atomizing nozzle extending out of the ring plate. The atomizing nozzle is provided with an arc-shaped atomizing spray channel and a rectangular high-pressure output channel. When material is fed from the top of the shell, and the raw material entering the shell is cement powder, the powder is prone to flying during its descent. The main function of the atomizing nozzle is to atomize the water flow. The atomized water flow collects the scattered powder, and the dispersed powder reacts with the small water droplets. After combination, the mixture naturally falls under the influence of gravity. The atomizing nozzle is equipped with an arc-shaped atomizing spray channel and a rectangular high-pressure output channel. The arc-shaped atomizing spray channel is mainly used to output arc-shaped water mist, while the rectangular high-pressure output channel is mainly used to output water column. The water column is used to impact the falling powder, disperse the powder, and prevent the powder from falling directly and forming a powder pile inside the shell. The atomizing nozzle is connected to the rotating shaft through a ring plate, tripod, and rotating shaft, which further improves the collection effect of the atomizing nozzle on the scattered powder and the impact effect on the falling powder.
[0010] Furthermore, the adjustment assembly includes a limiting plate disposed on the inner side of the ring plate, a spring disposed at the connection between the limiting plate and the ring plate, a slot is formed inside the atomizing nozzle, the spring is installed inside the slot, and several tracks are disposed on the limiting plate; the limiting plate is connected to the atomizing nozzle through the spring, and the limiting plate is provided with several tracks, each track having a different thickness, the tracks of different thicknesses are arranged in a ring and located at different heights on the limiting plate, and a transition area is provided between each track, the drive rod changes the height of the atomizing nozzle inside the housing through the partition and the rotating shaft, and the drive rod controls the connection between the atomizing nozzle and the spring and the tracks of different thicknesses by changing the height of the atomizing nozzle.
[0011] Furthermore, the atomizing nozzle includes an arc-shaped sleeve installed inside the ring plate. The arc-shaped sleeve is slidably connected to the ring plate, and a vertical plate is installed on the outer side of the arc-shaped sleeve. A through hole is provided in the middle of the arc-shaped sleeve, and the output end of the through hole is rectangular. When the drive rod is in the lowest state, there is a gap between the arc-shaped sleeve and the ring plate, which serves as an arc-shaped atomizing spray channel. The ring plate is a hollow structure. At this time, water inside the ring plate is output through the arc-shaped atomizing spray channel and the through hole under pressure. The through hole is a rectangular high-pressure output channel. During operation, the drive rod lifts the atomizing nozzle to a designated track. Firstly, the distance between the designated track and the ring plate is minimized. The track pushes the arc-shaped sleeve through a spring, causing the arc-shaped sleeve to... When the outer wall is completely in contact with the inner wall of the ring plate, the arc-shaped atomizing spray channel is blocked at the output end, and the spring is squeezed and completely retracted into the slot, so that the outer wall of the track is in contact with the outer wall of the arc sleeve, and the input end of the rectangular high-pressure output channel is blocked by the outer wall of the track. Secondly, when the distance between the designated track and the ring plate is short, the spring is in a compressed state, and the arc sleeve is in contact with the ring plate under the action of the spring. At this time, the arc-shaped atomizing spray channel is blocked at the output end, and there is a gap between the arc sleeve and the limiting plate due to the action of the spring, so the input end of the rectangular high-pressure output channel is in an open state. Thirdly, when the distance between the designated track and the ring plate is the shortest, both the arc-shaped atomizing spray channel and the rectangular high-pressure output channel are in a flowing state. Both the spring and the limiting plate are permanent magnets on the side where they are connected, and the end of the spring near the limiting plate is equipped with a ball bearing, which reduces the friction loss generated between the spring and the track during the sliding of the spring. At the same time, the magnetic force keeps one end of the spring in contact with the track. The drive rod can control the connection between the atomizing nozzle and the corresponding track during concrete mixing, according to actual needs. Firstly, during powder mixing, the arc-shaped atomizing spray channel and the rectangular high-pressure output channel are opened to collect scattered powder and disperse falling powder. Secondly, during powder mixing, the arc-shaped atomizing spray channel and the rectangular high-pressure output channel are closed, working with the mixing blades to achieve only a cooling effect. Thirdly, during the cleaning of the inner wall of the outer shell, the arc-shaped atomizing spray channel and the rectangular high-pressure output channel are opened to rinse the inner wall of the outer shell and collect flying dust, or the rectangular high-pressure output channel can be opened alone to increase the impact intensity of the rectangular water flow. The limit plate is equipped with several tracks of different thicknesses, and each track has several [tracks / features].
[0012] Furthermore, the partition is slidably connected to the rotating shaft, and the sliding stroke of the partition is less than the height of a single track; the partition is slidably connected to the rotating shaft, and the sliding stroke of the partition is less than the height of a single track, that is, when the drive rod is in its shortest state, the fixed shaft and the rotating shaft produce a jumping effect through the toothed blocks, but the jumping height of the rotating shaft is less than the height of a single track, and the rotating shaft does not drive the partition to rise or fall when it jumps.
[0013] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This high-speed concrete mixing equipment with temperature control function, through the setting of the mixing blades, the mixing blades are located at different heights inside the concrete. During the rotation of the mixing blades, the mixing blades disturb the concrete inside the shell to realize the movement of the concrete inside the shell. At the same time, the mixing blades located at different heights absorb heat from the concrete inside the concrete at different heights through the internal water flow, avoiding the accumulation of a large amount of heat inside the concrete. 2. This high-speed concrete mixing equipment with temperature control function, through the setting of mixing blades and baffles, the main function of the baffles is to form a water flow channel inside the rotating shaft so that the water flow can directly enter the mixing blades after entering the main shaft, and then absorb the heat inside the concrete through the mixing blades. At the same time, the mixing blades rotate and extend during the lifting and lowering of the baffles so that the mixing blades can scrape off the concrete adhering to the inner wall of the outer shell. 3. This high-speed concrete mixing equipment with temperature control function, through the setting of the ring plate and atomizing nozzles, and by changing the connection state between the atomizing nozzles and the track through the drive rod, achieves different water spraying effects from the atomizing nozzles. The atomized water flow collects the scattered powder, and the water column is used to impact the falling powder, dispersing the powder and reducing the loss caused by the falling powder being scattered. At the same time, it impacts the falling powder to prevent the powder from falling directly and forming a powder pile inside the shell. Attached Figure Description

[0017] Please see Figures 1-8 The present invention provides a technical solution: a high-speed concrete mixing equipment with temperature control function, including a shell 1, an inlet pipe, an outlet pipe and a water pipe arranged on the outside of the shell 1, a water pump and a water inlet pipe installed on the water pipe, the water pipe being connected to the main shaft 2 and the ring plate 4, a drive motor and the main shaft 2 installed on the shell 1, the main shaft 2 being hollow and penetrating the upper end cover of the shell 1, the main shaft 2 being composed of a fixed shaft 201 and a rotating shaft 202; The fixed shaft 201 and the rotating shaft 202 are respectively connected to the outer casing 1 and the drive motor. The connection between the fixed shaft 201 and the rotating shaft 202 is sleeved. The fixed shaft 201 and the rotating shaft 202 are connected by the drive rod 8. The connection between the fixed shaft 201 and the rotating shaft 202 is provided with toothed blocks 203. Several partitions 7 are provided inside the main shaft 2. The partitions 7 divide the inside of the main shaft 2 into several spaces. The upper end of the drive rod 8 is connected to the partitions 7. The main function of the baffle 7 is to form a water flow channel inside the rotating shaft 202 so that the water flow can directly enter the mixing blade 6 after entering the main shaft 2, and then absorb the heat inside the concrete through the mixing blade 6. At the same time, the baffle 7 drives the mixing blade 6 to rotate and extend during the lifting and lowering process, so that the mixing blade 6 can scrape off the concrete adhering to the inner wall of the outer shell 1. The outer casing 1 has two tripods 3, and an annular plate 4 is installed on the outside of the two tripods 3. Several atomizing nozzles 5 are provided on the annular plate 4. The atomizing nozzles 5 are distributed in a ring on the annular plate 4. Each atomizing nozzle 5 includes an arc-shaped sleeve 501 installed inside the annular plate 4. The arc-shaped sleeve 501 is slidably connected to the annular plate 4. A vertical plate 502 is installed on the outside of the arc-shaped sleeve 501. A through hole 503 is provided in the middle of the arc-shaped sleeve 501. The output end of the through hole 503 is rectangular. The number of atomizing nozzles 5 is odd. An adjustment component 11 is provided at the connection between the atomizing nozzles 5 and the ring plate 4. The adjustment component 11 is used to change the length of the atomizing nozzles 5 extending out of the ring plate 4. The atomizing nozzles 5 are provided with an arc-shaped atomizing spray channel and a rectangular high-pressure output channel. The drive rod 8 changes the connection state between the atomizing nozzle 5 and the track, so that the atomizing nozzle 5 can produce different water spraying effects. The atomized water flow collects the scattered powder, and the water column is used to impact the falling powder, disperse the powder, reduce the loss caused by the falling powder being scattered, and impact the falling powder to prevent the powder from falling directly and forming a powder pile inside the outer shell 1. The adjustment assembly 11 includes a limiting plate 1101 disposed inside the ring plate 4, a spring 1102 disposed at the connection between the limiting plate 1101 and the ring plate 4, a slot is provided inside the atomizing nozzle 5, the spring 1102 is installed inside the slot, and several tracks are provided on the limiting plate 1101. Several stirring blades 6 are provided on the lower outer wall of the main shaft 2. The stirring blades 6 are arranged in a ring on the outside of the main shaft 2. The stirring blades 6 are set at different heights on the main shaft 2. Both the ring plate 4 and the stirring blades 6 are hollow. The mixing blades 6 are located at different heights inside the concrete. During rotation, the mixing blades 6 disturb the concrete inside the outer shell 1 to enable the concrete to move inside the outer shell 1. At the same time, the mixing blades 6 located at different heights absorb heat from the concrete inside the concrete at different heights through the internal water flow, thus avoiding the accumulation of a large amount of heat inside the concrete. Each space is connected to a single stirring blade 6. The upper end of the space is connected to the ring plate 4. A drive rod 8 is installed below the partition plate 7. The stirring blade 6 is composed of two staggered hollow plates. A labyrinth channel is set inside the stirring blade 6. A drive assembly 9 is set between the two hollow plates. The drive assembly 9 is connected to the partition plate 7. Several water outlets 601 are opened at the lower end of the hollow plate. Several vertical arc strips 602 are set on the hollow plate. A rack 701 is provided on one side of the partition 7. The drive assembly 9 includes a connecting shaft 901 provided on one side of the rack 701. The connecting shaft 901 is meshed with the rack 701. A bushing 902 is sleeved at the end of the connecting shaft 901. The bushing 902 is connected to the hollow plate. The connecting shaft 901 and the bushing 902 are threaded together. The partition 7 is slidably connected to the rotating shaft 202, and the sliding stroke of the partition 7 is less than the height of a single track.
[0018] Working principle of the invention: The fixed shaft 201 and the rotating shaft 202 are connected by a drive rod 8. When the drive rod 8 controls the fixed shaft 201 and the rotating shaft 202 to be in contact with each other, the upper end of the rotating shaft 202 is connected to the output shaft of the drive motor. During the operation of the drive motor, the rotating shaft 202 is driven to rotate synchronously. At the same time, the adjacent sides of the fixed shaft 201 and the rotating shaft 202 are provided with tooth blocks 203. The lower end of the fixed shaft 201 is connected to the outer shell 1. With the cooperation of the drive motor and the tooth blocks 203, the rotating shaft 202 reciprocates relative to the fixed shaft 201. The reciprocating state of the rotating shaft 202 manifests as a vibration effect on the stirring blade 6. The bending part of the tooth block 203 is provided with an arc transition, and the tooth block 203 is made of a highly wear-resistant material. The mixing blade 6 is connected to the rotating shaft 202. During operation, the rotating shaft 202 drives the mixing blade 6 to rotate inside the outer shell 1, mixing the raw materials inside the outer shell 1. Since both the main shaft 2 and the mixing blade 6 are hollow structures, and the mixing blade 6 has a labyrinth channel inside, the water inlet pipe introduces water into the channels inside the main shaft 2 and the mixing blade 6 through the water pipe. At the same time, the water pump realizes the water flow circulating inside the main shaft 2 and the mixing blade 6. During the movement of the water flow in the labyrinth channel inside the mixing blade 6, the water flow absorbs the heat inside the concrete through the mixing blade 6, and the water flow achieves a cooling effect on the concrete during mixing. The surface of the mixing blade 6 is provided with several vertical arc strips 602 to further improve the mixing effect of the mixing blade 6. A heat dissipation device is installed on the water pipe. The water flow, driven by the water pump, pushes the water carrying heat through the heat dissipation device so that the heat carried by the water flow can be quickly output. The partition 7 is connected to the drive rod 8, which is used to push the partition 7 up and down. The partition 7 is slidably connected to the rotating shaft 202. During the period when the drive rod 8 pushes the partition 7 up and down relative to the rotating shaft 202, the connecting shaft 901 slides relative to the rotating shaft 202. Since the partition 7 is engaged with the connecting shaft 901 through the rack 701, and since the stirring blade 6 is composed of two horizontally distributed and interlocking hollow plates, the hollow plate closer to the rotating shaft 202 is connected to the rotating shaft 202 through the bushing 902, and the one farther away from the rotating shaft 202 is connected to the rotating shaft 202 through the bushing 902. The hollow plate on one side of shaft 202 is connected to partition 7 through connecting shaft 901 and bushing 902. During the lifting and lowering of partition 7, connecting shaft 901 is driven to rotate around bushing 902. Connecting shaft 901 and bushing 902 are threadedly connected. The two hollow plates are separated by bushing 902 and connecting shaft 901 in the rotating state. Since the surface of the hollow plate is provided with several vertical arc strips 602, the various areas on a single arc strip 602 are staggered, causing the concrete attached to the surface of mixing blade 6 to fall off. When the drive rod 8 is in its shortest state, the two hollow plates on the mixing blade 6 are separated. At this time, the concrete inside the outer shell 1 has been completely discharged, and the outer shell 1 is in a cleaning state. After the hollow plates are separated, the width of the mixing blade 6 increases, and the side of the mixing blade 6 is in contact with the inner wall of the outer shell 1. At this time, the drive motor rotates, which drives the mixing blade 6 to clean the inner wall of the outer shell 1 through the rotating shaft 202. The bushing 902 is fixedly connected to the rotating shaft 202. The bushing 902 is connected to the hollow plate on the side near the rotating shaft 202 through a bearing, and the connecting shaft... 901 is fixedly connected to the hollow plate on the side away from the rotating shaft 202, so that when the connecting shaft 901 rotates, the connecting shaft 901 and the bushing 902 drive the hollow plates to separate from each other, and drive the stirring blade 6 to rotate as a whole through the hollow plate on the side away from the rotating shaft 202. When the drive rod 8 is in the shortest state, the stirring blade 6 is in a vertical state. Several water outlets 601 are opened at the lower end of the hollow plate. When the hollow plates are staggered, the water outlets 601 under the two hollow plates are in an overlapping state, and some water inside the stirring blade 6 is directly output through the water outlets 601. When the material is cement powder, it tends to fly around during its descent. The atomizing nozzle 5 is mainly used to atomize the water flow. The atomized water flow collects the scattered powder. After the dispersed powder combines with the small water droplets, the mixture falls naturally under the action of gravity. The atomizing nozzle 5 is equipped with an arc-shaped atomizing spray channel and a rectangular high-pressure output channel. The arc-shaped atomizing spray channel is mainly used to output arc-shaped water mist, and the rectangular high-pressure output channel is mainly used to output water column. The water column is used to impact the falling powder and disperse it, preventing the powder from falling directly and forming a powder pile inside the outer shell 1. The atomizing nozzle 5 is connected to the rotating shaft 202 through the ring plate 4, the tripod 3, and the atomizing nozzle 5, which further improves the collection effect of the atomizing nozzle 5 on the scattered powder and the impact effect on the falling powder. The limiting plate 1101 is connected to the atomizing nozzle 5 via the spring 1102. Several tracks are provided on the limiting plate 1101, each track having a different thickness. The tracks of different thicknesses are arranged in a ring and located at different heights on the limiting plate 1101. A transition area is provided between each track. The drive rod 8 changes the height of the atomizing nozzle 5 inside the housing 1 via the partition 7 and the rotating shaft 202. By changing the height of the atomizing nozzle 5, the drive rod 8 controls the connection between the atomizing nozzle 5 and the spring 1102 with the tracks of different thicknesses. When the drive rod 8 is in its lowest position, there is a gap between the arc-shaped sleeve 501 and the ring plate 4. This gap is an arc-shaped atomizing spray channel. The ring plate 4 is a hollow structure. At this time, the water inside the ring plate 4 is output through the arc-shaped atomizing spray channel and the through hole 503 under pressure. The through hole 503 is a rectangular high-pressure output channel. During the operation of the structure inside the outer shell 1, the drive rod 8 lifts the atomizing nozzle 5 to move to the designated track. Firstly, when the distance between the designated track and the ring plate 4 is the shortest, the track pushes the arc sleeve 501 through the spring 1102, so that the outer wall of the arc sleeve 501 is completely in contact with the inner wall of the ring plate 4. At this time, the arc atomizing spray channel is blocked at the output end, and the spring 1102 is squeezed and completely stored in the slot, so that the outer wall of the track is in contact with the outer wall of the arc sleeve 501, and the input end of the rectangular high-pressure output channel is blocked by the outer wall of the track. Secondly, when the distance between the designated track and the ring plate 4 is relatively short, the spring 1102 is in a compressed state. At this time, the arc sleeve 501 is in contact with the ring plate 4 under the action of the spring 1102. At this time, the arc atomizing spray channel is blocked at the output end. Due to the action of the spring 1102, there is a gap between the arc sleeve 501 and the limiting plate 1101, so the input end of the rectangular high-pressure output channel is in an open state. Thirdly, when the distance between the designated track and the ring plate 4 is the shortest, both the arc atomizing spray channel and the rectangular high-pressure output channel are in a flowing state. Both the spring 1102 and the limiting plate 1101 are permanent magnets on the side they are connected to, and the end of the spring 1102 near the limiting plate 1101 is provided with a ball, which reduces the friction loss generated between the spring 1102 during its sliding on the track. At the same time, the magnetic force keeps one end of the spring 1102 in contact with the track. The drive rod 8 can control the connection between the atomizing nozzle 5 and the corresponding track during concrete mixing according to actual needs. Firstly, during the powder mixing process, the arc-shaped atomizing spray channel and the rectangular high-pressure output channel are opened to collect the scattered powder and disperse the falling powder. Secondly, during the powder mixing process, the arc-shaped atomizing spray channel and the rectangular high-pressure output channel are closed, and the mixing blade 6 is used to achieve only the cooling effect. Thirdly, during the cleaning of the inner wall of the outer shell 1, the arc-shaped atomizing spray channel and the rectangular high-pressure output channel are opened to rinse the inner wall of the outer shell 1 and collect the flying dust, or the rectangular high-pressure output channel is opened alone to increase the impact intensity of the rectangular water flow. The limiting plate 1101 is provided with several tracks of different thicknesses. Each track is provided with several partitions 7 that are slidably connected to the rotating shaft 202. The sliding stroke of the partitions 7 is less than the height of a single track. The partitions 7 are slidably connected to the rotating shaft 202, and the sliding stroke of the partitions 7 is less than the height of a single track. That is, when the drive rod 8 is in its shortest state, the fixed shaft 201 and the rotating shaft 202 produce a jumping effect through the toothed block 203. However, the jumping height of the rotating shaft 202 is less than the height of a single track, and the rotating shaft 202 does not drive the partitions 7 to rise or fall when jumping.
