202results about How to "Stable mix" patented technology

The invention relates to waste sintered brick and tile environment-friendly lightweight concrete and a preparation method thereof, and belonging to the technical field of concrete. The lightweight concrete is prepared from the following raw materials: cement, water, waste sintered bricks and tiles, fly ash, slag, silica fume, polyacrylonitrile fibers, plastic steel fibers, polyphenyl granules, ceramic powder, silica powder, a polycarboxylate superplasticizer and phenolic resin. Through the synergistic effect of the raw materials, the lightweight concrete has good compressive strength and flexural strength under the condition of ensuring that the lightweight concrete has a relatively low heat conductivity coefficient, and meanwhile, the lightweight concrete also has good frost resistance. In the preparation method of the environment-friendly lightweight concrete, the waste sintered bricks and tiles and the soaking water are premixed, and the fly ash and the adsorption water are premixed, so that the influence of the waste sintered bricks and tiles and the fly ash on the mixing effect of the raw materials due to water adsorption is reduced, and the raw materials are uniformly and stably mixed.

A totally aerated combustion burner having a combustion plate with a multiplicity of flame holes includes a distribution chamber, a mixing chamber, and an air supply chamber. The mixing chamber has a front surface with a plurality of nozzle holes disposed in parallel with, and at a lateral distance from, one another so that a fuel gas to be ejected from the nozzle holes and the primary air from the air supply chamber get mixed in the mixing chamber. A wall plate is disposed upright on a bottom surface of the mixing chamber in a manner to lie opposite to the front surface of the mixing chamber while leaving a ventilation clearance to the front surface. An air inlet is formed in such a portion at the bottom surface of the mixing chamber as to face the ventilation clearance.

The invention discloses a mixer and application thereof. The mixer is provided with at least one thin conveying pipe, a thick conveying pipe, and a mixed slurry output pipe, wherein the pipe diameter of the thick conveying pipe is more than that of the thin conveying pipe, and one end of the thick conveying pipe is sealed; the mixed slurry output pipe is communicated with the sidewall close to the sealed end of the thick conveying pipe and changes the material flowing direction; the at least one thin conveying pipe extends into the thick conveying pipe from the sealed end, the extension amount of the thin conveying pipe in the thick conveying pipe exceeds the communication port of the thick conveying pipe and the mixed slurry output pipe, and the thin conveying pipe is partially overlapped with the thick conveying pipe; and the caliber of the mixed slurry output pipe is increased from the communication port with the thick conveying pipe to a discharge port. According to the invention, the shortcomings in the prior art are overcome, and high-efficiency and smooth mixing of two fluids with greater flow difference is realized.
