Description

Technical Field

[0001] The invention relates to the technical field of cement fineness detection, and more specifically to a cement coarseness detection device. Background Art

[0002] The fineness of cement is an important indicator of cement quality. The higher the fineness, the smaller the particle size and the larger the surface area of ​​cement. This helps to increase the chemical reaction between cement particles and the degree of reaction during the hardening process of cement, thereby improving the strength of cement. Therefore, by testing the coarseness of cement, it is possible to ensure that the quality of cement meets the standards and the quality of concrete: cement is an important component of concrete, and its fineness directly affects the quality and performance of concrete. Too coarse cement particles are not conducive to the activity of cement. It is generally believed that cement particles less than 40μm (0.04mm) have higher activity. Therefore, by testing the coarseness of cement, it can be determined whether the fineness of the cement used is appropriate, thereby ensuring the quality of concrete. Different projects have different requirements for cement. Some projects require high-strength and high-durability concrete, while some projects pay more attention to the constructability and economy of concrete. By testing the coarseness of cement, the specific application scope of cement with different fineness can be determined to meet the needs of the project. When the cement particles are too fine, although the early strength will be increased, the energy consumption and cost of grinding will also increase, and it is not suitable for long-term storage. In addition, when cement is too fine, it will produce a large volume shrinkage during the hardening process. Therefore, by testing the coarseness of cement, the particle size distribution of cement can be optimized and the utilization efficiency of cement can be improved.

[0003] The negative pressure sieving instrument for cement fineness is an important device for testing cement fineness. It uses the negative pressure sieving method to screen cement particles to determine their coarseness and fineness. Some preparation work is required before cement testing, including the preparation of test samples. First, take some cement samples to ensure that the cement samples are representative to reflect the coarseness and fineness of the overall cement. Due to the physical properties of cement, it is easy to clump. After the cement sample is placed in the container, it needs to be shaken and stirred. By shaking, the tester can initially destroy the agglomeration of the cement sample and initially disperse the cement particles, providing more space for subsequent mixing. Favorable conditions are created to improve stirring efficiency. If cement samples containing lumps are stirred directly, stirring too quickly may break the cement samples and affect the subsequent test accuracy. Testers can only use a stirring rod to slowly stir the cement samples, which may not immediately disperse the lumps completely, resulting in uneven stirring and affecting the screening results. Therefore, it is necessary to shake first and then stir. After the cement sample is adjusted evenly, use an electronic balance to weigh an appropriate amount of cement sample. For example, for an 80μm sieving test, 25g of sample is usually weighed; for a 45μm sieving test, 10g of sample is weighed, accurate to 0.01g.

[0004] However, when preparing samples for testing cement coarseness, manual shaking and stirring of cement samples rely on experience and are time-consuming and laborious. In view of this, we propose a cement coarseness detection device. Summary of the invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention sets a rotating mechanism as a driving structure. When the clamping mechanism is disengaged from the rotating mechanism, a cement sample stirring structure is formed, and the cement in the cement sample preparation tank is shaken to shake the cement. When the clamping mechanism is clamped and connected with the rotating mechanism to form the cement sample stirring structure, the cement in the cement sample preparation tank is stirred to make the cement sample uniform, thereby making the subsequent cement coarseness detection data accurate, so that when preparing the cement fineness detection sample, there is no need for manual shaking and stirring, which saves time and effort, and solves the current technical problem of time-consuming and labor-intensive preparation of cement coarseness detection test samples.

[0023] 2. The present invention also designs the structure of the stirring mechanism so that the rotation direction of the central gear is opposite to that of the two side gears, thereby making the stirring component B and the stirring component A rotate in opposite directions, so that the stirring effect of the stirring component B and the stirring component A when preparing the cement fineness detection sample is better, and the cement fineness detection sample is prepared more evenly, thereby making the cement fineness detection more accurate.

[0024] 3. The present invention designs a clamping mechanism so that when the two clamping blocks slide to respectively engage with the two clamping gears, the clamping gears cannot rotate, thereby making the connecting shaft A and the connecting shaft B unable to rotate, and further making the component B and the stirring component A unable to rotate. When the two clamping blocks slide into the slide groove A, the clamping blocks are disengaged from the clamping gears. At this time, the top circular plate and the ball segment block form a relatively fixed structure. The rotation of the ball segment block can drive the top circular plate to rotate, and the rotating adjustment ring can make the two inclined guide grooves rotate accordingly, so that the movable ring block moves on the inclined guide groove, causing the two movable rods to respectively drive the two clamping blocks to slide in opposite structures in the two slide grooves B. The adjustment is convenient, time is saved, and the current technical problem of time-consuming and labor-intensive preparation of test samples for cement coarseness detection is further solved.

[0025] 4. The present invention further designs the plug-in assembly so that when adjusting, the adjusting rod is held and lifted up, the spring A is compressed, and the plug-in column block is disengaged from the plug-in hole, so that the adjusting ring can rotate. The adjusting rod is directly rotated to cause the adjusting ring to rotate until the plug-in column block is relative to another plug-in hole, and the engaging block just engages with the engaging gear, or the engaging block disengages from the engaging gear and just completely slides into the slide groove A. At this time, release your hand, and under the elastic force of the spring A, the plug-in column block is plugged into the plug-in hole, so that the adjusting ring and the top circular plate rotate synchronously, ensuring that the position of the engaging block will not automatically shift, and the adjustment is more convenient.

[0026] 5. The present invention arranges the mounting seat, the rotating mechanism, the stirring mechanism, the clamping mechanism and the external gear mechanism so that when the two clamping blocks slide to respectively clamp with the two clamping gears, the clamping gears cannot rotate, and the internal gear ring is meshed with the two side gears so that the entire rotating mechanism cannot rotate. The external control mechanism controls the motor output shaft to rotate rapidly, which can drive the rotating shaft, the ball block, the swing ball block and the slide groove A to rotate synchronously. The ball block moves in the swing guide groove, driving the stirring mechanism, the clamping mechanism and the external gear mechanism to swing at the same time, and the stirring components A and B of the stirring mechanism cannot rotate, thereby reducing the stirring speed. Component A and stirring component B affect the fineness of the cement sample. When the two clamping blocks slide into the slide groove A, the clamping blocks are disengaged from the clamping gears. At this time, the top circular plate and the ball segment block form a relatively fixed structure. The motor output shaft is controlled by an external control mechanism to rotate slowly to drive the ball segment block to rotate, and the top circular plate rotates. At this time, due to the sliding connection between the arc slider of the external tooth mechanism and the swing groove, the entire external tooth mechanism cannot rotate. When the top circular plate rotates, the entire stirring mechanism rotates accordingly, causing the two side gears to perform planetary rotation stirring along the inner gear ring, thereby driving the center gear to rotate relatively in the opposite direction to stir the fineness of the cement sample.

[0027] 6. The present invention further designs the connecting groove and the cement sample preparation tank, and sets the guide groove to have a gradually expanding structure from top to bottom, so that the guide groove is used for guiding and is convenient for alignment. After the cement sample to be prepared is placed on the cement sample preparation tank, the snap-in ball block is aligned with the wide part of the bottom end of the guide groove, and the cement sample preparation tank is moved upward. At this time, the spring B is in a compressed state, and the snap-in ball block is guided by the cement sample preparation tank and moves to the narrow part of the top end of the quasi-guide groove. At this time, the cement sample preparation tank is rotated and moved, and the snap-in ball block moves along the arc groove until the snap-in ball block enters the snap-in ball groove, and a relatively fixed structure is formed by the elastic force of the spring B to prevent the cement sample preparation tank from falling when the rotating mechanism rotates. The cement sample preparation tank is easy to disassemble and install, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

The present invention further designs the connecting groove 83, and sets the guide groove 831 to be a structure gradually expanding from top to bottom, so that the guide groove 831 is used for guiding and is easy to align.

[0059] In the embodiment of the present invention, a cement sample preparation tank 9 is arranged at the bottom end of the external tooth mechanism 8, and a collar 91 is fixedly provided at the top of the cement sample preparation tank 9, and the collar 91 is sleeved on the connecting ring 81. A number of movable grooves 92 are provided in the collar 91 in a circular and equidistant structure relative to the number of the snap-in ball grooves 833. A limiting block 93 is slidably connected in the movable groove 92, and the limiting block 93 is elastically connected to the movable groove 92 by a spring B94. A snap-in ball block 95 is fixedly provided at the centripetal end of the limiting block 93, and the snap-in ball block 95 is movably matched with the guide groove 831, and the snap-in ball block 95 is movably matched with the arc groove 832, and the snap-in ball block 95 is snap-fitted with the snap-in ball groove 833. The present invention further designs the cement sample preparation tank 9 so that after the cement sample to be prepared is placed in the cement sample preparation tank 9, the snap-in ball block 95 is aligned with the wide part at the bottom end of the guide groove 831, and the cement sample preparation tank 9 is moved upward. At this time, the spring B94 is in a compressed state, and the snap-in ball block 95 is guided by the cement sample preparation tank 9 and moved to the narrow part at the top end of the quasi-guide groove 831. At this time, the cement sample preparation tank 9 is rotated and moved, and the snap-in ball block 95 moves along the arc groove 832 until the snap-in ball block 95 enters the snap-in ball groove 833, and forms a relatively fixed structure through the elastic force of the spring B94, so as to prevent the cement sample preparation tank 9 from falling when the rotating mechanism 5 rotates. The cement sample preparation tank 9 is easy to disassemble and install, saving time and effort.

[0060] Working principle: This embodiment provides a cement coarseness detection device. When in use, put cement into the cement sample preparation tank 9, align the clamping ball block 95 with the wide part at the bottom end of the guide groove 831, and move the cement sample preparation tank 9 upward. At this time, the spring B94 is in a compressed state, and the clamping ball block 95 is guided by the cement sample preparation tank 9 and moves to the narrow part at the top end of the quasi-guide groove 831. At this time, the cement sample preparation tank 9 is rotated and moved, and the clamping ball block 95 moves along the arc groove 832 until the clamping ball block 95 enters the clamping ball groove 833, and forms a relatively fixed structure through the elastic force of the spring B94.

[0061] The two clamping blocks 75 are respectively clamped with the two clamping gears 64, the clamping gears 64 cannot rotate, and mesh with the two side gears 67 through the inner gear ring 86, so that the entire rotating mechanism 5 cannot rotate. The external control mechanism controls the output shaft of the motor 51 to rotate rapidly, which can drive the rotating shaft 52, the ball block 53, the swinging ball block 54 and the slide groove A55 to rotate synchronously. The ball block 53 moves in the swinging guide groove 613, driving the stirring mechanism 6, the clamping mechanism 7, the external gear mechanism 8 and the cement sample preparation tank 9 to swing at the same time, and the lumps in the cement sample preparation tank 9 are shaken off, and the stirring components A66 and B611 of the stirring mechanism 6 cannot rotate, reducing the influence of the stirring components A66 and B611 on the fineness of the cement sample;

[0062] Hold the adjusting rod 773 and lift it up, the spring A772 is compressed, and the plug-in column block 774 is disengaged from the plug-in hole 612, so that the adjusting ring 71 can rotate. The adjusting rod 773 is directly rotated to cause the adjusting ring 71 to rotate until the plug-in column block 774 is opposite to the other plug-in hole 612, or the clamping block 75 is disengaged from the clamping gear 64 and just completely slides into the slide groove A55. At this time, release your hand. Under the elastic force of the spring A772, the plug-in column block 774 is plugged into the plug-in hole 612, so that the adjusting ring 71 and the top circular plate 60 rotate synchronously, ensuring that the position of the clamping block 75 will not automatically shift. At this time, the clamping block 75 is disengaged from the clamping gear 64, and the top circular plate 60 and the ball segment block 53 form a relatively fixed structure. The output shaft of the motor 51 is controlled by the external control mechanism to rotate slowly to drive the ball segment block 53 to rotate, and the top circular plate 60 rotates. At this time, due to the sliding connection between the arc slider 85 of the external gear mechanism 8 and the swing groove 42, the entire external gear mechanism 8 cannot rotate. When the top circular plate 60 rotates, the entire stirring mechanism 6 rotates accordingly, causing the two side gears 67 to stir along the inner gear ring 86 in a planetary rotation, thereby driving the central gear 610 to rotate relatively in the opposite direction to stir the fineness of the cement sample;

[0063] After the cement coarseness test sample is prepared, the cement sample preparation tank 9 is removed and several portions of cement samples are weighed using an electronic balance.

[0064] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
