Description

Technical Field

[0001] The utility model relates to the technical field of cement heavy metal content detection, in particular to a homogenizing device for cement heavy metal content detection. Background Art

[0002] Cement is an important building material, which is made by burning raw materials such as lime, silicate and alumina. Its main components are calcium oxide, silicate and alumina, and generally do not contain heavy metal elements.

[0003] However, there are some special cements that are produced through cement kiln co-processing technology. The cement kiln co-processing technology is to mix solid waste and liquid waste with the raw materials required in the cement production process after special treatment, and carry out pyrolysis reaction at high temperature, so that the solid waste and liquid waste are effectively treated, and the combustible organic matter therein can be recycled. Since the raw materials of cement kiln co-processing technology are solid waste and liquid waste, these solid waste and liquid waste may contain heavy metals, so the cement prepared by cement kiln co-processing technology also contains a certain amount of heavy metals.

[0004] Heavy metal content detection mainly refers to the detection and analysis of heavy metal content of metals or metalloids such as mercury, cadmium, lead, chromium, arsenic, or heavy metals with certain toxicity such as copper, zinc, nickel, cobalt, tin, etc.

[0005] The current heavy metal content detection is to crush the cement blocks produced by high-temperature calcination in cement kiln co-disposal technology, then pour them into distilled water for stirring and dissolving, and take cement liquid samples for subsequent heavy metal content detection. However, due to the high density of cement itself, the density of heavy metals is also high. After the cement is stirred and dissolved, it is very easy to precipitate at the bottom of the cement liquid. Conventional cement liquid sampling may cause the heavy metal content detected in the sampled cement liquid to be inconsistent with the actual content.

[0006] Therefore, it is necessary to design a homogenizing device for detecting heavy metal content in cement, which can homogenize the cement liquid and then accurately detect the heavy metal content when sampling the cement liquid, without too large an error with the actual heavy metal content.

[0028] A homogenizing device for detecting heavy metal content in cement comprises a cement slurry stirring assembly, a cement slurry stirring cup 8 and a stirring cup placement block 2. The cement slurry stirring cup 8 is placed on the stirring cup placement block 2, and the cement slurry stirring assembly homogenizes the cement slurry in the cement slurry stirring cup 8. After homogenization and stirring, the cement slurry with heavy metal content to be detected is sampled and sent to a heavy metal content detection instrument, and the heavy metal content of the cement is detected by the heavy metal content detection instrument.

[0029] The cement slurry stirring assembly includes a base 1, a support column 3 is fixedly installed at the rear of the base 1, and a stirring motor mounting arm 4 is fixedly installed on the top of the support column 3. In order to ensure the stability of the homogenizing device during operation, the base 1, the stirring cup placement block 2, the support column 3 and the stirring motor mounting arm 4 can all be made of steel material, the support column 3 is welded and fixedly installed at the rear of the base 1, and the stirring motor mounting arm 4 is welded and fixedly installed on the top of the support column 3.

[0030] A cement slurry stirring motor 5 is installed at the front end of the stirring motor mounting arm 4. The rotating shaft 6 of the cement slurry stirring motor 5 passes through the stirring motor mounting arm 4, and a cement slurry homogenizing component 7 is fixedly installed at the bottom of the rotating shaft 6.

[0031] The bottom of the rotating shaft 6 is provided with a bottom connecting piece 601, which is an external threaded column, and the bottom connecting piece 601 is rotatably connected to the top connecting piece 701 of the cement slurry homogenizing component 7. The thread rotation direction of the bottom connecting piece 601 and the top connecting piece 701 is opposite to the rotation direction of the cement slurry stirring motor 5. Such a design can prevent the cement slurry homogenizing component 7 from falling off during the rotation of the cement slurry stirring motor 5.

[0032] The cement slurry stirring cup 8 contains cement slurry with a heavy metal content to be detected. The cement slurry stirring cup 8 is made of transparent hard plastic, and the stirring condition of the cement slurry in the cement slurry stirring cup 8 can be clearly seen.

[0033] A cement slurry mixing cup placement groove 201 is arranged on the top of the mixing cup placement block 2, the inner diameter of the cement slurry mixing cup placement groove 201 is equal to the outer diameter of the cement slurry mixing cup 8, and a layer of anti-slip rubber pad is arranged on the surface of the cement slurry mixing cup placement groove 201, which can better fix the cement slurry mixing cup 8 and prevent the cement slurry mixing cup 8 from tipping over.

[0034] The mixing cup placement block 2 can be placed on one side of the base 1. A magnetic attraction component is provided at the contact point between the base 1 and the mixing cup placement block 2, and the base 1 and the mixing cup placement block 2 can be connected by magnetic attraction.

[0035] The cement slurry homogenizing component 7 includes a rotating cylindrical body 702, the top of which is a top connector 701, and the top connector 701 is an internal thread groove. The top periphery of the rotating cylindrical body 702 is provided with two splash-proof strips 705, which are made of rubber material and are directly inserted into the top of the rotating cylindrical body 702 and pass through to form four short splash-proof strips. The design of the four short splash-proof strips can effectively prevent the cement slurry in the cement slurry mixing cup 8 from overflowing.

[0036] The bottom end of the rotating cylindrical body 702 is a conical centering cone head 703, and the centering cone head 703 can ensure that the cement slurry homogenizing component 7 rotates at a high speed along its own center line.

[0037] The outside of the rotating cylindrical body 702 is provided with a spirally ascending stirring fan 704, and the stirring fan 704 spirally extends from the top of the centering cone head 703 to the bottom of the splash-proof strip 705. The setting of the stirring fan 704 can effectively lift the cement slurry at the bottom of the cement slurry stirring cup 8 to the top of the cement slurry by spiral ascending stirring, thereby avoiding the precipitation of the heavy metal-containing part in the cement slurry due to excessive density, resulting in the heavy metal content detected in the sampled cement liquid being inconsistent with the actual content.
