Abstract
The invention discloses a sulfate tester with an impurity removing device. The sulfate tester comprises a refrigeration system, a water circulation system, a test piece box and a heating system arranged inside of the test piece box, wherein the water circulation system comprises a water tank and a circulating water pump; the circulating water pump consists of a first water pump and a second water pump; a water outlet at the bottom of the water tank is connected with a water inlet at the upper part of the test piece box via the first water pump so as to form a water inlet system; a water returning opening at the bottom of the test piece box is connected with a water returning opening at the top of the water tank via the second pump so as to form a water returning system; and the sulfate tester further comprises the impurity removing device. According to the invention, the impurity removing device, namely a circular water storage machine, is arranged between the water returning opening and the second water pump at the bottom of the test piece box in the water returning system, and then the dropping materials and the impurities mixed in the water are precipitated at the bottom of the impurity removing device, so that the dropping materials and the impurities are fully separated from the water and the service life of the sulfate tester is prolonged.
Description
Technical field
The invention belongs to the building materials instrument field, relate to a kind of sulfate testing machine with the impurity scavenge unit
Background technology
As everyone knows, concrete is the building structural materials that consumption is maximum, usable range is the widest.But owing to having a large amount of objectionable constituent and other environmental factors in underground water or soil, cause concrete to be corroded, make the hydraulic performance declines such as its intensity, permanance and volume stability, cause a large amount of economic losses and casualties.According to domestic and international many studies show that, particularly remarkable to the corrosion that concrete causes with sulfate in these chemical corrosion phenomenons, have a strong impact on the permanance of concrete component.
Concrete sulphate attack is to cause one of major reason of concrete durability destruction, and especially for list structure engineerings such as railway, highways, xoncrete structure can often face the corrosion of sulfate.In soil, all contain a large amount of sulfate in alkaline land, underground water, seawater, these sulfate penetrate into inside concrete, in itself and concrete, a series of physics chemical action can occur in some mineral matters, concrete structural strength lowers, volume stability descends thereby make, have a strong impact on concrete permanance, therefore, usually need to detect concrete sulphate attack performance with the concrete sulphate testing machine.
Sulfate testing machine commonly used mainly comprises refrigeration system, water circulation system, test specimen case and the heating system that is located at test specimen case inside; Water inlet system in water circulation system is connected through the water inlet of water pump with the test specimen case by water outlet of water tank; Return water system in water circulation system is connected with the water container backwater mouth through water pump by the water return outlet of test specimen case.In process of the test, concrete sample can generating portion come off.Yet; when water flowed out from the water return outlet of test specimen case, cast and impurity can be mixed in water, when the water that is mixed with cast, impurity enters water pump and cooling tube; it usually can make water pump and cooling tube be corroded, stop up, thereby greatly reduces the serviceable life of concrete sulphate testing machine.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of sulfate testing machine with the impurity scavenge unit.
For achieving the above object, technical scheme of the present invention is as follows: a kind of sulfate testing machine with the impurity scavenge unit comprises refrigeration system, water circulation system, test specimen case and the heating system that is located at test specimen case inside; Described water circulation system comprises water tank and water circulating pump; Described water circulating pump is comprised of the first water pump and the second water pump; The water delivering orifice of described water tank bottom connects and composes water inlet system through the water inlet of the first water pump and test specimen upper box part; The water return outlet of described test specimen case bottom connects and composes return water system through the water return outlet of the second water pump and tank top; Also comprise the impurity scavenge unit, this impurity scavenge unit is located between the water return outlet and the second water pump of test specimen case bottom in return water system.
Related content in technique scheme is explained as follows:
1, in such scheme, described impurity scavenge unit is a circular water receiver.
2, in such scheme, described impurity scavenge unit is located at the bottom of described refrigeration system.
3, in such scheme, described the second water pump water inlet pipe be located at the top of described impurity scavenge unit, and contact with the water surface in described impurity scavenge unit.
4, described heating system is heating rod, and this heating rod is arranged on the below of described test specimen case.
Due to the utilization of the technical program, the present invention compared with prior art has following advantages:
Between the water return outlet of the present invention's employing test specimen case bottom in return water system and the second water pump, the impurity scavenge unit is set, i.e. circular water receiver.And with the water inlet pipe look of the second water pump also on the top of impurity scavenge unit, and contact with the water surface in it, after water flows in the impurity scavenge unit from the water return outlet of test specimen case, the impurity scavenge unit can play the effect of precipitation to water wherein, namely, the cast that is mixed with in water, impurity can be deposited in the bottom of impurity scavenge unit, make cast, impurity fully separate with water, thereby avoided that disengaging thing, impurity cause that suction pump, cooling tube etc. are corroded, stopping state occurs, greatly extended the serviceable life of sulfate testing machine.
