Description

Triple cement mortar stirring device for engineering test detection

Technical Field

The utility model relates to a concrete quality detects technical field, concretely relates to engineering test detects with trigeminy formula cement mortar agitating unit.

Background

The cement mortar mixer is one of the necessary equipment for cement factories, construction units, related professional institutions and scientific research units and cement laboratories. The cement mortar stirrer is mainly applied to the stirring step in the cement strength test piece forming process, and the stirring relationship of mortar is water, cement and mortar mixing uniformity, so that the final strength of the cement test piece is greatly influenced. It is known that the strength of cement is one of the most important test indexes, and the detection result of the laboratory cement strength greatly influences the judgment of the construction site on the use of building materials, and if the judgment is wrong, serious engineering quality accidents are most likely to be caused.

The existing cement mortar intensity stirrer comprises: the device mainly comprises a motor, a sand adding box, a transmission box, a main shaft, stirring blades, a stirring pot, a base, an upright post, a support, an outer cover, a controller and the like. Firstly, manually pouring weighed mixing water into a pot, then switching on a power supply of a stirrer, cleaning the stirring pot and stirring blades by wet cloth, then adding weighed cement into the pot, pouring standard sand into a sand adding box, starting the power supply for stirring, firstly stirring at a low speed for 30 s+/-1 s, uniformly adding sand when the second 30 s+/-1 s, stirring at a high speed for 30 s+/-1 s, stopping for 90s, putting down the stirring pot within 15 s+/-1 s after stopping stirring, scraping the rubber sand of the blades, the pot wall and the pot bottom into the pot by a scraper, and stirring at a high speed for 60 s+/-1 s. And (5) discharging the stirring pot after stopping for subsequent steps. After the test is finished, the blades and the stirring pot are manually cleaned, and the test can be used by the next test person after all cleaning is finished. However, the existing cement mortar intensity mixer has the following defects:

1. the manual weighing of the mixing water is too complicated, and if the molding quantity is too large, the test efficiency is greatly reduced.

2. During feeding, the sample is raised dust at the moment of dumping, which threatens the health of experimental personnel.

3. After stopping stirring, the rubber sand on the stirring ruler and the inner wall of the stirring pot is required to be scraped, and the existing mode is manual, so that the labor intensity is high and the efficiency is low.

4. After the test is finished, a tester needs to manually take the stirring pot to a water tank for cleaning, the process is tedious, and the time is consumed.

5. When the instrument is operated, only a single or single group of tests can be completed by a single person, so that the simultaneous use of multiple persons cannot be realized, the cost is increased when multiple instruments are purchased, and the economic benefit is reduced.
