Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically a device for rapidly determining the disintegration coefficient of red sandstone on-site. Background Technology

[0002] Red sandstone is a sedimentary rock formed by the staining of iron oxides. Its striking brick-red color originates from the oxidation of hematite or limonite in its mineral composition. This type of rock is mainly formed by the long-term cementation of quartz sand grains and often contains clay minerals and carbonate impurities. It has a fine texture and distinct stratification. Its bright color and hard texture make it highly sought after in the field of building materials and it is often used for carving, exterior wall decoration, and landscape stone.

[0003] Red sandstone disintegration test is an important experiment for evaluating its durability. It mainly simulates the rock breaking process under natural weathering. The test usually places standard rock samples in a controlled environment (such as circulating water flow, freeze-thaw cycle or chemical solution) and characterizes the rock's weathering resistance by quantifying the disintegration rate, debris particle size distribution and mass loss.

[0004] When conducting water immersion disintegration tests on dried red sandstone, repeated soaking and drying are required, and readings must be taken. The testing process is quite complex and cumbersome. Therefore, a device for rapid on-site determination of the disintegration coefficient of red sandstone is needed to meet people's needs.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: a device for rapidly determining the disintegration coefficient of red sandstone on site, including a test device body 1; in order to conduct red sandstone disintegration tests more quickly and simply, a base 2 is provided on the test device body 1, and an soaking cylinder 3 and a drying cylinder 4 are installed on the base 2. The red sandstone is soaked and disintegrated in the soaking cylinder 3 and dried and dehydrated in the drying cylinder 4, and the red sandstone mass reading is read.

[0029] To facilitate sample immersion and disintegration, the immersion cylinder 3 is equipped with an immersion cylinder partition plate 31, which evenly divides the interior of the immersion cylinder 3 into multiple independent immersion zones 32. A magnetic capsule limiting groove 33 is provided at the bottom of each immersion zone 32, and a magnetic capsule 34 is placed within the magnetic capsule limiting groove 33. A first motor groove 35 is provided in the base 2, and a first motor 36 is installed within the first motor groove 35. The first motor groove 35 is located below the magnetic capsule limiting groove 33. A magnet 37 is installed on the motor shaft of the first motor 36, and the magnet 37 is compatible with the magnetic capsule 34. Through the lifting rod 21 and the rotating motor 22, the support frame 24 is controlled to transfer the dried sample from the drying zone 42 to the immersion zone 32. The immersion zone 32 is then filled with... With clean water covering the sample surface, the first motor 36 is started, and the magnetic capsule 34 is rotated via the magnet 37 on the motor shaft. To prevent the magnetic capsule 34 from being thrown off due to excessive rotation speed, a magnetic capsule limiting groove 33 is provided at the bottom of the soaking area 32. The magnetic capsule 34 rotates within the magnetic capsule limiting groove 33. The rotation of the magnetic capsule 34 drives the clean water in the soaking area 32 to rotate, using the water flow to accelerate the disintegration of the red sandstone. The water flow speed is limited so as not to generate a large external force that would seriously affect the disintegration rate of the red sandstone. The reading is observed through the display panel 26, and the start time of disintegration is recorded. After one disintegration is completed, the sample on the support frame 24 is lifted above the water surface by the lifting rod 21, and the surface moisture is drained.

[0030] Example 2: As Figure 5 and 6 To facilitate the drying and moisture removal of samples, a drying drum 4 is equipped with a drying drum partition plate 41, which evenly divides the interior of the drying drum 4 into multiple independent drying zones 42. A fan vent 43 is located at the bottom of each drying zone 42, and a fan is installed inside the fan vent 43. A fan motor slot 44 is located inside the base 2, and a fan motor 45 is installed inside the fan motor slot 44. The fan motor slot 44 is located below the fan vent 43. An electric heating plate 46 is installed inside the drying zone 42, positioned between the fan vent 43 and the support frame 24. The support frame 24, carrying the sample, is controlled by a lifting rod 21 and a rotating motor 22. The samples are placed inside the drying zone 42 of the drying cylinder 4. The fan motor 45 and the electric heating plate 46 inside the drying cylinder 4 are started to dry each sample. At the same time, the fan removes loose particles from the sample surface. After a certain period of drying, the moisture in each sample is dried, and the mass of the sample remains constant. The top of the support frame 24 is connected to the electronic scale 25. The reading can be observed through the display panel 26 on the electronic scale 25. When the reading no longer changes, it indicates that the drying is complete. At this time, the fan motor 45 and the electric heating plate 46 are turned off. The reading on the display panel 26 is read and recorded again. The remaining features are the same as in Example 1.

[0031] Example 3: As Figure 3A lifting rod 21 is installed on the base 2. A rotary motor 22 is installed at the top of the lifting rod 21. A top bracket 23 is installed on the rotary motor 22. Several support frames 24 are provided at the bottom of the top bracket 23. The support frames 24 are adapted to the soaking area 32 and the drying area 42. An electronic scale 25 is installed on the top bracket 23. The electronic scale 25 is provided with a display panel 26. The support frames 24 are connected to the electronic scale 25. The top of the support frame 24 is connected to the electronic scale 25. The reading can be observed through the display panel 26 on the electronic scale 25. The remaining features are the same as in Embodiment 1.

[0032] The working principle is as follows: Before conducting the disintegration test, multiple red sandstone samples with consistent dimensions are taken and tested simultaneously under the same conditions to minimize random errors. Each sample is cleaned and placed sequentially on the support frame 24. The support frame 24, carrying the samples, is then moved into the drying zone 42 of the drying cylinder 4 via the lifting rod 21 and the rotary motor 22. The fan motor 45 and electric heating plate 46 inside the drying cylinder 4 are activated to dry each sample. Simultaneously, the fan removes loose particles from the sample surface. After a certain drying time... The moisture in each sample is dried, and the sample mass remains constant. The top of the support frame 24 is connected to the electronic scale 25, and the reading can be observed through the display panel 26 on the electronic scale 25. When the reading no longer changes, it indicates that drying is complete. At this time, the fan motor 45 and the electric heating plate 46 are turned off. The reading on the display panel 26 is read and recorded again as the initial reading (drying mass of the rock sample before disintegration). After reading, the fan motor 45 is turned on to accelerate sample cooling. After the sample cools to room temperature, the support frame 24 is controlled by the lifting rod 21 and the rotary motor 22 to carry the dried sample from the... The sample is transferred from drying zone 42 to soaking zone 32, which is filled with water that covers the sample surface. The first motor 36 is started, and the magnetic capsule 34 rotates via magnet 37 on the motor shaft. To prevent the magnetic capsule 34 from being thrown off due to excessive speed, a magnetic capsule limiting groove 33 is provided at the bottom of soaking zone 32. The magnetic capsule 34 rotates within the magnetic capsule limiting groove 33. This rotation of the magnetic capsule 34 causes the water in soaking zone 32 to rotate, accelerating the disintegration of the red sandstone through water flow. The limited water flow speed prevents the generation of excessive external force that could severely impact the red sandstone. The disintegration rate is observed and read on display panel 26, and the start time of disintegration is recorded. After one disintegration is completed, the sample on support frame 24 is lifted above the water surface by lifting rod 21. After the surface moisture is drained, the sample is transferred from soaking zone 32 to drying zone 42 by lifting rod 21 and rotary motor 22 for drying. After drying, the sample mass reading after one disintegration is read and recorded. The above drying and soaking disintegration process is repeated until the obtained mass reading no longer changes, and the final reading (residual dried mass of disintegrated rock sample) is obtained. The formula is used to calculate the mass of the sample. (where I) dI is the disintegration resistance coefficient; mr is the residual dried mass of the disintegrated rock sample; ms is the dried mass of the rock sample before disintegration. The disintegration resistance coefficient is calculated. d If the percentage is ≥30%, the red sandstone is considered to have resistance to disintegration and good engineering performance.

[0033] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The scope of protection of this utility model does not involve any improvement to the software and methods.
