Description

Technical Field

[0001] The technical field to which the present invention belongs is the technical field of building material preparation and construction, and in particular, relates to a swaying magnetic chain drainage, exhaust and dense slurry device and method. Background Art

[0002] With the development and update of building material preparation and construction technology, and the diversification and complexity of building design, the grouting path often becomes tortuous and complicated, making it difficult to achieve the ideal compaction effect. Bubbles and excess moisture are easily left inside the slurry, thus affecting the overall performance of the grouting body. The existing forming stage adopts a vibration process to compact the slurry. The vibration modes include horizontal vibration, vertical vibration, etc., or a vibrating rod is used to pull the slurry back and forth to compact the slurry. The disadvantage is that it is easy to cause resonance of the trolley and generate high-frequency noise. At the same time, it is also easy to cause leakage of the mold frame due to vibration. Summary of the invention

[0003] The purpose of the present invention is to provide a device and method for compacting slurry by swaying magnetic chains to drain and exhaust air, so as to solve the problems of noise generated by vibration and defoaming and slurry leakage from the mold frame.

[0004] In order to solve the above problems, the technical solution of the present invention is: A swaying magnetic chain drainage, exhaust and dense slurry device comprises a truss manipulator and a track. A plurality of trolleys are arranged on the track. Each trolley passes by the truss manipulator in sequence. A bracket is fixedly connected to the lower end of the Z axis of the truss manipulator, a cross plate is connected to the bracket, and a plurality of electromagnets are connected to the cross plate in sequence.

[0005] A reduction motor and a conductive slip ring are installed on the bracket, the middle part of the cross plate is fixedly connected to the lower end of the reduction motor shaft, each electromagnet is electrically connected to one end of the conductive slip ring, and the other end of the conductive slip ring is connected to the output end of the controller.

[0006] A first photoelectric switch for detecting the position of the trolley is provided on the input side of the truss manipulator, a second photoelectric switch for detecting the Z-axis position of the truss manipulator is provided on the upper end of the truss manipulator, and a liquid level switch is installed on the cross plate. The liquid level switch, the first photoelectric switch and the second photoelectric switch are connected to the controller input end.

[0007] A method for a swaying magnetic chain drainage and air-draining slurry compacting device comprises the following steps: S1: preparing slurry, including mixing water and composite cement in proportion as slurry carrier, adding magnetic particles, and adding additives as auxiliary agents to prepare magnetic convergence slurry, and injecting the slurry into each mold frame on the trolley through a grouting device; S2: The trolley carries the slurry and passes under the truss manipulator. During the process, the controller controls the truss manipulator to immerse the cross plate into the slurry, and controls the electromagnet to energize and the reduction motor to rotate, forming moving magnetic flux lines. The magnetic chain is subjected to the changing magnetic force, forming magnetic chain swing. During the swinging process, the old chain breaks and the new chain is formed, causing disturbance inside the slurry, giving the bubbles and water an initial power. The bubbles and water are discharged from the slurry due to the lift; S3: After defoaming the slurry in the mold frame below the truss manipulator, the controller controls the truss manipulator to retract, and then the next trolley drives under the truss manipulator to defoam and compact the slurry on the next trolley according to the method of step S2.

[0008] The magnetic convergence slurry is prepared by mixing water and composite cement in proportion as slurry carriers, adding iron sand, iron oxide, cobalt oxide or nickel oxide as magnetic suspended particles, and adding surfactants and anti-dispersants as auxiliary agents. Sulphoaluminate cement replaces 30% of silicate cement as composite cement, the water-cement ratio is 0.4-0.8, the magnetic particles account for 10%-30% of the total mass of the slurry, and the slurry carrier accounts for 70%-90% of the total mass.

[0009] The slurry is prepared by mixing water and composite cement in proportion as a slurry carrier, adding sand as an aggregate, and adding auxiliary agents to compound, wherein sulphoaluminate cement replaces 30% of silicate cement as the composite cement, the water-cement ratio is 0.4-0.8, and sand accounts for 10%-30% of the total mass.

[0010] The beneficial effects of the present invention are: 1. The slurry is defoamed by magnetically driven swaying magnetic chains, giving the bubbles initial momentum, and the bubbles and water are discharged from the slurry, reducing the porosity of the slurry after solidification, improving the material performance, and can achieve silent defoaming without affecting the mold frame sealing. It is also suitable for magnetic convergence slurry and slurry, and has a wide range of applications.

[0011] 2. The magnetic convergence slurry proposed in the present invention, under the action of the magnetic field, drives the slurry to move in a directional manner and gather near the magnetic source to form a long magnetic chain. In order to further improve the density of the slurry and optimize the performance of the material, the magnetic chain swings to disturb the bubble water inside the slurry, and the bubble water is discharged from the slurry due to the density difference.

[0012] 3. When preparing magnetic convergence slurry, the viscosity of the slurry can be precisely controlled by adjusting the amount or type of resin added. By continuously monitoring the gradual solidification process of the viscosity of the magnetic convergence slurry, the slurry formula or the parameters of the shaking compaction equipment can be adjusted in time to ensure the continuous improvement of the slurry density and quality. The magnetic particles are gradually added to the slurry one by one, which can intuitively visualize the strength of the magnetic chain magnetic field and the distribution of the magnetic field, which helps to achieve precise control of the magnetic field strength and slurry density.
