Description

Technical Field

[0001] The utility model belongs to the technical field of water absorption measurement, and particularly relates to a tooling for measuring the water absorption rate of bentonite. Background Art

[0002] Bentonite, also known as montmorillonite, is a non-metallic mineral mainly composed of montmorillonite. It has good physical and chemical properties and can be used as a purification decolorant, binder, thixotropic agent, suspending agent, catalyst, etc., and is widely used in agriculture, light industry, cosmetics, pharmaceuticals and other fields. Bentonite has various colors, such as white, light yellow, light gray and light green, its density is 2 - 3 g / cm 3 , its hardness is 1 - 2, and its main chemical components are silicon dioxide, aluminum oxide and water. There are many types of bentonite, including sodium-based bentonite, calcium-based bentonite, hydrogen-based bentonite, organic bentonite, etc.

[0003] The water absorption rate of bentonite is an important index of the quality of bentonite. The relevant national standard measurement method does not stipulate the specific equipment structure. Most of the existing devices for measuring the water absorption rate of bentonite are single porous ceramic plates in a cube shape, without providing corresponding containers. On the one hand, these existing devices take a long time during the experiment, and the efficiency of measuring only a single sample at a time is low. On the other hand, it is difficult to control conditions such as the water volume and water level during the experiment. Moreover, the water absorption rates of different types of bentonite are different. During the experiment, samples with a large water absorption rate will cause the water level to drop, resulting in a difference in the water level before and after the experiment, thus causing the final experimental result to be on the low side. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a tooling for measuring the water absorption rate of bentonite, which can measure multiple samples at one time, reduce the experiment time, improve the measurement efficiency, and ensure the constancy of the water level during the test, thereby ensuring the accuracy of the experiment.

[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is:

[0006] A tool for measuring the water absorption rate of bentonite, comprising a glass container. A first water tank is provided in the glass container, and a second water tank is provided inside the glass container.

A buzzer is installed on the signal converter, and the buzzer is electrically connected to the signal converter. A radar water level gauge, a thermometer, and a micro-float type water level valve are respectively installed at one end of the first water tank close to the signal converter. The radar water level gauge, the thermometer, and the micro-float type water level valve are all electrically connected to the signal converter. The input end of the micro-float type water level valve is communicated with the second water tank.

[0023] A tool for measuring the water absorption rate of bentonite, including a glass container 14, a first water tank 9 is provided in the glass container 14, a second water tank 10 is provided inside the glass container 14, a water inlet is provided on one side of the end of the glass container 14, the water inlet is communicated with the second water tank 10, a signal converter 1 is installed at one end of the glass container 14 close to the water inlet, a buzzer 13 is installed on the signal converter 1, the buzzer 13 is electrically connected to the signal converter 1, a radar water level gauge 4, a thermometer 5, and a micro-float type water level valve 3 are respectively installed at one end of the first water tank 9 close to the signal converter 1, the radar water level gauge 4, the thermometer 5, and the micro-float type water level valve 3 are all electrically connected to the signal converter 1, the input end of the micro-float type water level valve 3 is communicated with the second water tank 10, a water passing hole is provided at the bottom of the first water tank 9, and the first water tank 9 can be communicated with the second water tank 10 through the water passing hole, a rubber plug 11 is installed in the water passing hole, a water outlet pipe 7 is communicated and installed on the second water tank 10, a valve is installed on the water outlet pipe 7, and a plurality of porous ceramic plates 12 are placed inside the first water tank 9.

[0024] A glass plate is installed above the first water tank 9, through which sundries during the experiment can be prevented from entering, thereby avoiding the water body inside the first water tank 9 from being polluted by sundries. Four adjustable bases 8 are installed at the lower ends of the glass container 14, and the adjustable bases 8 are made of rubber material, so as to reduce the vibration of the glass container 14 and extend the service life of the glass container 14. A glass spirit level 6 is installed at one end of the top of the glass container 14 away from the signal converter 1. Through the glass spirit level 6, it can be judged whether the glass container 14 is placed horizontally, so as to keep the water level plane consistent during the experiment and ensure the consistency of water absorption in all directions of the bentonite. A dust-proof plug 2 is installed in the water inlet, and sundries are prevented from entering the second water tank 10 through the dust-proof plug 2.

[0025] A tooling for measuring the water absorption rate of bentonite, and its working process is as follows: Before the experiment, first seal the water passing hole at the bottom of the first water tank 9 with a rubber plug 11, place a plurality of porous ceramic plates 12 in the first water tank 9, inject water into the first water tank 9 until it submerges the porous ceramic plates 12, soak the porous ceramic plates 12, let it stand for 2 hours until the porous ceramic plates 12 are soaked, and after no bubbles are generated, open the rubber plug 11 to lower the water level in the first water tank 9 to 6 mm below the upper surface of the porous ceramic plates 12, then close the rubber plug 11. At this time, the micro-float type water level valve 3 can sense the water level in the first water tank 9. When the water level in the first water tank 9 is too low, the float type water level valve opens, and the water in the second water tank 10 flows into the first water tank 9 through the micro-float type water level valve 3 to keep the water level constant at the position where the water surface is 6 mm below the upper surface of the porous ceramic plates 12 during the experiment. The whole experiment process should be carried out in a constant temperature room at 20 °C. The water temperature in the first water tank 9 is detected by a thermometer 5. When the water temperature exceeds 20 °C ± 2 °C, the thermometer 5 transmits a signal to the signal converter 1, and the signal converter 1 makes the buzzer 13 emit an alarm through the signal converter 1.

[0026] During the experiment, first immerse the filter paper in the first water tank 9 for 30 s to make it water-absorbed saturated, place it on the porous ceramic plate 12, and at most 4 filter papers can be placed on each porous ceramic plate 12. The edges of each filter paper should be more than 1 cm apart. At most 12 samples can be analyzed simultaneously each time.

[0027] After the filter paper is stabilized, gently pick up and weigh the filter paper with tweezers, record the weight, and place the weighed samples on the filter paper respectively, with a spreading diameter of about 9 cm. During the experiment, the bentonite will absorb water and gradually reach a saturated state.

[0028] During the experiment, due to the continuous water absorption of the bentonite, the water level in the first water tank 9 will drop. At this time, the micro-float type water level valve 3 will open, and gradually supplement the water in the second water tank 10 to the first water tank 9. When the water level in the second water tank 10 is lower than that in the first water tank 9, the water in the second water tank 10 cannot be supplemented to the first water tank 9 in time. When the water shortage exceeds 30 s, the radar water level gauge 4 transmits a signal to the signal converter 1, and the signal converter 1 makes the buzzer 13 emit an alarm to prompt the experimenter to supplement water in time.

[0029] The design of the double water tanks formed by the first water tank 9 and the second water tank 10 and the connection of the two water tanks through the micro-float type water level valve 3 effectively dynamically compensates for the water level drop caused by the water absorption of the bentonite during the experiment, and is guaranteed by the radar water level gauge 4 to prevent the first water tank 9 from not being able to be supplemented with water in time due to the insufficient water level in the second water tank 10.

[0030] The above content is only an example and illustration of the structure of the present utility model. Those skilled in the art to which the present technology pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims of the present invention, they should fall within the protection scope of the present utility model.
