Description

Technical Field

[0001] The utility model belongs to the technical field of cement insoluble slag content determination, and in particular relates to a suction filtration mechanism and an automatic cement insoluble slag content determination instrument. Background Art

[0002] The composition of cement directly affects the strength and durability of buildings. With the in-depth development of cement technology, the types and amounts of admixtures are increasing. Adding admixtures to cement production can not only improve cement performance and reduce cement costs, but also make full use of various industrial waste residues and reduce environmental pollution caused by these industrial waste residues. However, excessive addition of admixtures will reduce the early strength of cement, lead to poor low-temperature performance and freeze-thaw resistance, and destroy the molecular structure of cement. Therefore, the new national standard for general-purpose silicate cement stipulates the types of admixtures added to cement and strictly stipulates the amount of admixtures added.

[0003] The national standard "Quantitative Determination of Cement Components" has very specific test methods and operating procedures for the determination of cement admixtures. According to this standard, the sample solution must first be stirred at 20±2°C for 30 minutes, and then the solution must be transferred to a sand core crucible for filtration. After filtration, it must be cleaned. After cleaning, the sand core crucible and insoluble slag must be dried at 105°C±5°C to constant weight, and then placed in a drying tower for cooling and weighing. In the determination of volcanic ash admixtures or fly ash components, the national standard stipulates that the filtration time cannot exceed 20 minutes. In the determination of granulated blast furnace slag components, the national standard stipulates that the filtration time cannot exceed 30 minutes. If the specified time is exceeded, the measurement results of the components will definitely deviate from the true value, so it is necessary to strictly monitor the time consumed by the solution filtration.

[0004] In the process of measuring cement insoluble residue, it is necessary to measure the filtration time of the solution. When the filtration time exceeds the national standard requirement, the experiment will be invalidated. At present, there is no cement insoluble residue measuring instrument on the market that can automatically measure the filtration time.

[0005] Patent CN215866242U proposes a cement insoluble slag measuring instrument, in which the stirring constant temperature bath assembly and the suction filtration drying box assembly are arranged horizontally. In order to realize the automatic measurement of the instrument, the instrument structure is very complex and the overall size is very large. In addition, the cement insoluble slag measuring instrument uses a peristaltic pump to extract and transfer the solution in the beaker to the sand core crucible. The pipette is inserted into the beaker, and the pipette is easy to interfere with the stirring bar in the beaker, and there is also the problem of incomplete solution extraction. In addition, the cement insoluble slag measuring instrument cannot measure the filtration time of the solution.

[0006] Patent CN114739852A proposes a cement insoluble slag measuring instrument with an upper and lower structure, which solves the problems of incomplete solution transfer and interference between the pipette and the stirrer. However, when measuring the components of granulated blast furnace slag, the measuring instrument requires the operator to prepare a sample solution with a pH of 11.6 by himself, so the automation level is not high enough. In addition, the cement insoluble slag measuring instrument cannot measure the filtration time of the solution. Utility Model Content

[0038] See also Figure 1 to Figure 2, is a timing device 6 in the suction filtration mechanism, comprising a fixing seat 1, a light source 2 and a photoelectric sensor 3, wherein the light source 2 and the photoelectric sensor 3 are mounted on the fixing seat 1, and the light source 2 and the photoelectric sensor 3 are arranged correspondingly, that is, the light source 2 and the photoelectric sensor 3 can be arranged relative to each other, or the light source 2 is arranged at a position where the photoelectric sensor 3 can detect light. Preferably, the photoelectric sensor 3 is connected to the electronic control unit. Preferably, a through hole is provided at the center of the fixing seat 1. An internal thread is provided on the through hole. When in use, the fixing seat 1 is mounted on a pipe through which the filtrate flows for measurement.

[0039] When in use, the light emitted by the light source 2 is scattered, refracted and absorbed by the pipeline, and the light energy distribution changes. The photoelectric sensor 3 detects the light intensity after scattering, refraction and absorption. When there is no liquid passing through the pipeline, the distribution of light energy is stable, and the light intensity detected by the photoelectric sensor 3 is a stable value. When there is liquid passing through the pipeline, the scattering, refraction and absorption effects are constantly changing due to the unstable state of the liquid. The light intensity detected by the photoelectric sensor 3 will be a changing value. By monitoring the light intensity value of the photoelectric sensor 3, it is possible to determine whether there is liquid passing, thereby measuring the time of liquid filtration.

[0040] See also Figures 1 to 3 , a suction filtration mechanism is provided for the present application, and the timing device 6 is installed on the suction filtration mechanism through a fixing seat 1. The filtration mechanism includes a sand core crucible 4, a crucible support 5, a timing device 6, a waste liquid barrel and a vacuum pump. The sand core crucible 4 is placed on the crucible support 5. The sand core crucible and the crucible support are detachably sealed and connected. The lower surface of the sand core crucible and the upper surface of the crucible support are both frosted to facilitate the sealing of the sand core crucible and the crucible support. In this structure, the sand core crucible and the crucible support must be able to be sealed (such as during filtration) and to be easily detached (such as during weighing). The present application achieves this effect by frosting the contact surface of the sand core crucible and the crucible support. In addition, it can also be sealed by adding a sealing ring between the bottom of the crucible and the crucible support. A drainage pipe connected to the waste liquid barrel is provided below the crucible support 5, and the waste liquid barrel is provided with interfaces respectively connected to the drainage pipe and the vacuum pump. The fixed seat 1 is installed at the bottom of the crucible support 5 or on the drainage pipe.

[0041] When in use, the sample solution transferred through the pipette flows into the sand core crucible 4. Under the suction action of the vacuum pump, the precipitate remains in the sand core. After the solution is filtered through the sand core, it flows into the crucible support 5. The straight pipe section of the crucible support 5 is provided with a timing device 6. The timing device 6 can monitor whether there is solution passing through the pipeline. A drain pipe connected to a waste liquid barrel is provided at the bottom of the crucible support 5. The waste liquid barrel has interfaces respectively connected to the drain pipe and the vacuum pump.

[0042] When no liquid passes through the crucible support 5, the distribution of light energy is stable, and the light intensity detected by the photoelectric sensor 3 is a stable value. When liquid passes through the crucible support 5, due to the unstable state of the liquid, the scattering, refraction and absorption effects are constantly changing, and the light intensity detected by the photoelectric detector will be a changing value. By monitoring the light intensity value of the photoelectric sensor 3, it is possible to determine whether liquid passes through, thereby measuring the time of liquid filtration.

The constant temperature water bath is provided with a water inlet joint and a water return joint connected to the constant temperature circulator assembly 13. The water temperature in the constant temperature circulator assembly 137 is controlled at 20°C ± 2°C. Under the suction action of the water pump, the water in the constant temperature circulator assembly 137 enters the bath assembly 8 from the water inlet joint on the outer shell, and then flows back to the constant temperature circulator assembly 137 from the water return joint on the outer shell. The constant temperature circulator assembly 137 includes a water tank, a circulating water pump, a refrigeration module and a heating module. The water tank is filled with water, and the circulating water pump, the refrigeration module and the heating module are all immersed in the water tank. The function of the constant temperature circulator is to keep the water temperature in the water tank at 20±2℃. When the water temperature is lower than 20±2℃, the heating module starts to heat the water in the water tank. When the water temperature reaches the target temperature, the heating module stops working. When the water temperature is higher than 20±2℃, the refrigeration module starts to cool the water in the water tank. When the water temperature reaches the target temperature, the refrigeration module stops working. The circulating water pump pumps the water in the water tank into the circulating water inlet of the bath assembly 8 and the liquid distribution tank assembly 9. The circulating water loops are connected to the return water port of the water tank, so that the bath assembly 8 and the liquid distribution tank are also maintained at 20±2℃.

The electric control module controls the rotation speed and angle of the multi-way rotating liquid adding head 25 and controls the amount of liquid added. The liquid adding component 7 can add the required reagent to the bath beaker or the liquid preparation box.

The stirring fan 32 sucks the gas in the drying box and passes it through the heating tube 31, bringing the heat of the heating tube 31 to the drying box, so as to dry the sand core crucible in the drying box. The ventilation unit functions to exchange the gas in the drying box with the outside gas. It is composed of an exhaust port 33 and an exhaust fan (not shown). When drying the sand core crucible, the exhaust fan starts to suck the gas in the drying box from the exhaust port 33, thereby exchanging the gas containing water vapor in the drying box to the outside of the instrument to ensure that the sand core crucible is completely dried.
