Description

Technical Field

[0001] This utility model relates to the technical field of silica measuring instruments, and in particular to a silica measuring instrument. Background Technology

[0002] The silica determination method is used to quickly and accurately detect the content of free silica in samples, and is widely used in occupational hazard detection, environmental monitoring, materials science and other fields.

[0003] In existing technologies, the determination of silica mostly relies on manual operation of instruments for reaction detection, followed by weighing. However, manual operation is not only prone to errors but also inefficient. Utility Model Content

[0004] In view of the technical problem that the determination of silicon dioxide in the prior art mostly relies on manual operation of the instrument for reaction detection, this utility model provides a silicon dioxide analyzer.

[0005] The technical solution adopted by this utility model is: a silica analyzer, including a box body, with side covers hinged to both sides of the box body, a peristaltic pump and a heating water tank fixedly connected inside the box body, a water pump inside the heating water tank, a sample tube and a beaker respectively installed on the two sides inside the box body, a filter paper funnel installed on the beaker, the peristaltic pump is used to draw the reagent in the sample tube into the beaker, and a stirring assembly is also provided inside the box body.

[0006] A further feature of this invention is that an electric slide rail is fixedly connected inside the box, a slider is slidably mounted on the electric slide rail, a heating module is fixedly connected to the top of the slider, and the sample cylinder is placed on the heating module.

[0007] The present invention is further configured such that the stirring assembly includes a first motor and a second motor connected to both sides inside the box, the output end of the first motor is fixedly connected to a first stirring rod, the output end of the second motor is fixedly connected to a second stirring rod, and linear slide rails are fixedly connected to the positions of the first motor and the second motor on both sides inside the box, and the sliders on the linear slide rails are fixedly connected to brackets, and the brackets are fixedly connected to the corresponding first motor and second motor.

[0008] The beneficial effects of this invention are as follows: In this invention, a heating water tank heats water, and a water pump adds the hot water to the sample cup via a peristaltic pump. Simultaneously, a portion of the peristaltic pump draws hydrochloric acid from the hydrochloric acid reagent bottle and enters the sample cylinder. Silica dissolves in pyrophosphoric acid and then precipitates as silica particles. The liquid in the sample cylinder slowly flows into a filtration device consisting of a filter paper funnel and a beaker under the control of the peristaltic pump. The silica, after undergoing a chemical reaction, becomes a solid and remains on the filter paper, while the remaining waste liquid is discharged downwards into the beaker for temporary storage. The weighing device first measures the total mass of the waste liquid and the silica on the filter paper, and then measures the new mass after the waste liquid is discharged. The silica content in the sample can be calculated by the mass difference. Thus, in this embodiment, automated operation is achieved, eliminating the need for excessive manual operation, improving efficiency, and reducing errors. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0017] To address the problems existing in the background art, this application proposes the following technical solution: a silica analyzer, comprising a housing 1, with side covers 2 hinged to both sides of the housing 1, a peristaltic pump 13 and a heating water tank 12 fixedly connected inside the housing 1, a water pump and an electric heating tube inside the heating water tank 12 for heating the water, a water pipe fixedly connected to the output end of the water pump, and the water pipe corresponding to the sample cylinder 5, a first pipe fixedly connected to the input end of the peristaltic pump 13, and a second pipe fixedly connected to the output end of the peristaltic pump 13, the first pipe corresponding to the sample cylinder 5 and the second pipe corresponding to the beaker 11.

[0018] In this embodiment, sample cylinders 5 and beakers 11 are installed on both sides of the interior of the housing 1. A filter paper funnel 10 is installed on the top of the beaker 11. A peristaltic pump 13 is used to draw the reagent in the sample cylinder 5 into the beaker 11. A stirring assembly is also provided inside the housing 1. A heating water tank 12 heats water, and the hot water is added to the sample beaker by the peristaltic pump 13 through the water pump. At the same time, part of the peristaltic pump 13 draws hydrochloric acid from the hydrochloric acid reagent bottle and enters the sample cylinder 5. The first motor 3 drives the first stirring rod 4 to rotate, so that the sample, hot water and hydrochloric acid in the sample cylinder 5 are fully mixed. The heating module 6 heats the sample and maintains the temperature within a fixed range to promote the reaction between the sample and pyrophosphoric acid and hydrochloric acid, so that the silica dissolves in the pyrophosphoric acid and then precipitates silica particles. After stirring for a certain period of time, the liquid in the sample cylinder 5 slowly flows into the filtration device composed of the filter paper funnel 10 and the beaker 11 under the control of the peristaltic pump 13.

[0019] In addition, an electric slide rail 7 is fixedly connected inside the housing 1. A slider is slidably mounted on the electric slide rail 7. A heating module 6 is fixedly connected to the top of the slider. The sample cylinder 5 is placed on the heating module 6. The heating module 6 can be a PTC electric heating plate used to heat the sample cylinder 5.

[0020] In this embodiment, the stirring assembly includes a first motor 3 and a second motor 8 connected to the two sides inside the housing 1. The output end of the first motor 3 is fixedly connected to a first stirring rod 4, and the output end of the second motor 8 is fixedly connected to a second stirring rod 9. Linear slide rails are fixedly connected to the positions of the first motor 3 and the second motor 8 on the two sides inside the housing 1, and the sliders on the linear slide rails are fixedly connected to brackets. The brackets are fixedly connected to the corresponding first motor 3 and second motor 8.

[0021] The usage method of this embodiment is as follows:

[0022] The sample containing silica was mixed with pyrophosphate and then placed in a sample cup;

[0023] The heating water tank 12 heats water, and the hot water is added to the sample cup via the peristaltic pump 13 through the water pump. At the same time, part of the peristaltic pump 13 draws hydrochloric acid from the hydrochloric acid reagent bottle and enters the sample cylinder 5.

[0024] The first motor 3 drives the first stirring rod 4 to rotate, so that the sample, hot water and hydrochloric acid in the stirring sample tube 5 are fully mixed. The heating module 6 heats the sample and maintains the temperature within a fixed range, promoting the reaction of the sample with pyrophosphoric acid and hydrochloric acid, so that the silica dissolves in the pyrophosphoric acid and then precipitates silica particles.

[0025] After stirring for a certain period of time, the liquid in the sample cylinder 5 slowly flows into the filtration device consisting of the filter paper funnel 10 and the beaker 11 under the control of the peristaltic pump 13.

[0026] The silica, after undergoing a chemical reaction, becomes a solid and remains on the filter paper, while the remaining waste liquid is discharged downwards into beaker 11 for temporary storage.

[0027] The weighing instrument first measures the total mass of the waste liquid and the silica on the filter paper. After the waste liquid is discharged, the new mass is measured again. The silica content in the sample can be calculated by the mass difference.
