Description

Technical Field

[0001] The invention belongs to the technical field of concrete detection, in particular to a device for detecting moisture content of concrete aggregates. Background Art

[0002] In the field of construction engineering, concrete is a widely used building material, and concrete aggregate is an important component of concrete. The moisture content of aggregate has a vital impact on the performance of concrete. The performance of concrete, such as strength and durability, is closely related to the moisture content of aggregate. Accurate determination of the moisture content of aggregate is of great significance for ensuring the quality of concrete. However, in the actual detection process, there are many factors that affect the accuracy of aggregate moisture content detection.

[0003] First, aggregates themselves are often non-uniform in particle size and distribution. If the aggregates entering the test are not uniform in this respect, the test results will be biased because aggregates of different sizes may have different internal moisture distribution states and how they interact with the test equipment. For example, large aggregates may have uneven moisture distribution inside, which makes it difficult to fully and accurately measure the true moisture content in the aggregates during moisture content testing.

[0004] Secondly, aggregates are often mixed with impurities, which can interfere with the moisture detection process and affect the accuracy of the test results. The presence of impurities may change the overall physical properties of the aggregate or produce additional reactions with the testing equipment, thereby interfering with the moisture measurement.

The output end of motor 2 passes through the side wall of the detection body and is fixedly connected to the feeding screw. The feeding screw is rotatably connected to the side wall of the inner cavity of the detection body.

[0008] In one embodiment of the present invention, the crushing assembly includes a motor 1, a crushing roller, a driving gear, and a driven gear. The two crushing rollers are rotatably connected to the side wall of the inner cavity of the feed box, the driving gear and the driven gear are rotatably connected to the side wall of the feed box, and the driving gear and the driven gear are meshingly connected. The motor 1 is fixedly connected to the other side wall of the feed box, and the output end of the motor 1 passes through the side wall of the feed box and is fixedly connected to a crushing roller, the other end of the crushing roller is fixedly connected to the driving gear, and the driven gear is fixedly connected to one end of the other crushing roller.

[0009] In one embodiment of the present invention, the stirring assembly includes motor three, a rotating drum, and stirring blades. Motor three is fixedly connected to the top of the feed trough. The output end of motor three passes through the top of the feed trough and is fixedly connected to the rotating drum, and the stirring blades are fixedly connected to the rotating drum.

[0010] In one embodiment of the present invention, the feed assembly includes a feed hopper, a solenoid valve, a feed barrel, and a cover plate. The feed barrel is fixedly connected to the top of the feed trough and penetrates into the inner cavity of the feed trough. The feed barrel is fixedly sleeved with a solenoid valve, the top of the feed barrel is fixedly connected to the feed hopper, and the top of the feed hopper is clamped with a cover plate.

[0011] In one embodiment of the present invention, the humidity analysis component includes a humidity processor, a suction pump, a delivery pipe, a constant temperature pipe, a feed pipe, and a filter box.

DETAILED DESCRIPTION

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] A concrete aggregate moisture content detection device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0021] like Figures 1 to 7 As shown, an embodiment of the present invention provides a concrete aggregate moisture content detection device, comprising: a bottom plate 1, a support plate 2 is symmetrically fixedly connected to the top of the bottom plate 1, a detection body 3 is fixedly connected to the top of the support plate 2, one end of the detection body 3 is fixedly connected to a discharge head 4, the other end of the detection body 3 is fixedly connected to a feed box 5, and the feed box 5 is connected to the inner cavity of the detection body 3, the top of the feed box 5 is fixedly connected to a feed trough 10, the inner cavity of the feed box 5 is provided with a crushing component 6, the inner cavity of the feed trough 10 is provided with a stirring component 11, the top of the feed trough 10 is symmetrically fixedly connected to a feed component 12, the inner cavity of the detection body 3 is provided with a feeding component 7, the inner cavity of the detection body 3 is fixedly connected to a material working cylinder 9, a de-impurity plate 13 is provided between the inner cavity side wall of the detection body 3 and the material working cylinder 9, and a humidity analysis component 8 is fixedly connected to the middle of the top of the bottom plate 1.

[0022] The humidity analysis component 8 includes a humidity processor 8.1, a suction pump 8.2, a delivery pipe 8.3, a constant temperature pipe 8.4, a feed pipe 8.5, and a filter box 8.6. The humidity processor 8.1 is fixedly connected to the top of the base plate 1, the suction pump 8.2 is fixedly connected to the top of the humidity processor 8.1, the output end of the suction pump 8.2 is fixedly connected to the delivery pipe 8.3, one end of the delivery pipe 8.3 is fixedly connected to the constant temperature pipe 8.4, one end of the constant temperature pipe 8.4 is fixedly connected to the feed pipe 8.5, one end of the feed pipe 8.5 is fixedly connected to the filter box 8.6, and the filter box 8.6 is connected to the humidity processor 8.1 through a pipeline.

[0023] In a specific application of the embodiment of the present invention, the concrete aggregate first enters the feed trough 10 through the feed assembly 12. The feed assembly 12 has a device with certain control functions, such as being able to adjust the speed and amount of feeding to ensure the stability of the subsequent detection process. Inside the feed trough 10, the stirring assembly 11 starts to work. The function of the stirring assembly 11 is to perform preliminary stirring on the aggregate entering the feed trough 10 to make the aggregate mix more uniform, which helps to obtain more representative samples in the subsequent detection process, because if the aggregate is uneven, it will lead to a large deviation in the detection result.

[0024] The crushing component 6 in the inner cavity of the feed box 5 crushes the aggregate after preliminary stirring and crushes the aggregate into appropriate particle sizes, which can increase the surface area of ​​the aggregate, which is conducive to the subsequent accurate detection of the moisture content of the aggregate by the moisture analysis component 8. The crushed aggregate enters the inner cavity of the detection body 3 through the feed box 5. The feeding component 7 in the inner cavity of the detection body 3 is responsible for conveying the aggregate entering from the feed box 5 to the material working cylinder 9. The feeding component 7 can feed at a certain rhythm and speed to ensure that the material is processed in an orderly manner in the detection body 3.

[0025] The extraction pump 8.2 is started to extract the sample containing aggregate from the material working cylinder 9. The suction force of the extraction pump 8.2 needs to be appropriate, which can effectively extract the sample without causing excessive interference to the material distribution in the material working cylinder 9. The sample extracted by the extraction pump 8.2 is transported through the delivery pipe 8.3. The delivery pipe 8.3 needs to have good sealing performance to prevent the sample from leaking during the transportation process or unnecessary water vapor exchange with the external environment, thereby affecting the accuracy of moisture content detection.

[0026] The sample then enters the constant temperature tube 8.4, which is used to control the temperature of the sample at a constant value. Because temperature has an impact on humidity detection, the accuracy of humidity detection can be improved by keeping the sample temperature constant. The sample after constant temperature treatment enters the filter box 8.6 through the feed pipe 8.5. In the filter box 8.6, the sample is filtered to remove impurities. If these impurities are not removed, they will interfere with the detection of the humidity processor 8.1, such as clogging the detection probe. The filtered sample then enters the humidity processor 8.1 through the pipeline, and the humidity processor 8.1 analyzes and calculates the moisture content of the concrete aggregate based on the relevant characteristics of the sample (such as electrical characteristics, etc.).

[0027] The impurity removal plate 13 arranged between the inner cavity side wall of the detection body 3 and the material working cylinder 9 can intercept some larger impurities in the aggregate during the transportation and processing of the aggregate, prevent these impurities from entering the material working cylinder 9 and then affecting the detection results of the humidity analysis component 8, and help to ensure the cleanliness of the inside of the equipment and reduce the risk of equipment failure.

[0028] In a possible embodiment, the feeding assembly 7 includes a motor 2 7.1 and a feeding screw 7.2. The motor 2 7.1 is fixedly connected to one side of the detection body 3. The output end of the motor 2 7.1 passes through the side wall of the detection body 3 and is fixedly connected to the feeding screw 7.2. The feeding screw 7.2 is rotatably connected to the side wall of the inner cavity of the detection body 3.

[0029] The crushing assembly 6 includes a motor 6.1, a crushing roller 6.2, a driving gear 6.3, and a driven gear 6.4. The two crushing rollers 6.2 are rotatably connected to the side wall of the inner cavity of the feed box 5. The driving gear 6.3 and the driven gear 6.4 are rotatably connected to the side wall of the feed box 5, and the driving gear 6.3 and the driven gear 6.4 are meshingly connected. The motor 6.1 is fixedly connected to the other side wall of the feed box 5. The output end of the motor 6.1 passes through the side wall of the feed box 5 and is fixedly connected to a crushing roller 6.2. The other end of the crushing roller 6.2 is fixedly connected to the driving gear 6.3. The driven gear 6.4 is fixedly connected to one end of the other crushing roller 6.2.

[0030] In a specific application of the embodiment of the present invention, when the motor 2 7.1 is started, the output shaft of the motor 2 7.1 starts to rotate. Since the output end of the motor 2 7.1 penetrates the side wall of the detection body 3 and is fixedly connected to the feeding screw 7.2, the rotation of the motor 2 7.1 drives the feeding screw 7.2 to rotate in the side wall of the inner cavity of the detection body 3. The rotation of the feeding screw 7.2 is like a screw advancing in a nut, and can push the concrete aggregate to be detected in the detection body 3 along the axial direction of the screw. This feeding method can achieve a relatively stable and controllable feeding speed, ensuring that the aggregate can continuously and evenly enter the relevant detection link during the subsequent detection process.

[0031] After the motor 1 6.1 is started, its output end will drive the crushing roller 6.2 fixedly connected thereto to rotate. One end of the crushing roller 6.2 is also fixedly connected to the driving gear 6.3, so when the crushing roller 6.2 rotates, the driving gear 6.3 will also rotate accordingly. Since the driving gear 6.3 is meshed with the driven gear 6.4, the rotation of the driving gear 6.3 will drive the driven gear 6.4 to rotate in the opposite direction. The driven gear 6.4 is fixedly connected to one end of the other crushing roller 6.2, so that the two crushing rollers 6.2 rotate in opposite directions. When the concrete aggregate enters between the two crushing rollers 6.2 from the feed box 5, the two crushing rollers 6.2 rotating in opposite directions will squeeze and crush the aggregate. In this way, larger particles of concrete aggregate can be crushed into smaller particles, which is conducive to more accurate detection of the moisture content of the aggregate, because the moisture content of the smaller particles of aggregate is more easily accurately measured by the detection equipment in the subsequent moisture content detection process, and the moisture distribution inside it is relatively more uniform, thereby improving the accuracy of the detection.

[0032] In a possible embodiment, the stirring assembly 11 includes a motor three 11.1, a rotating drum 11.2, and a stirring blade 11.3. The motor three 11.1 is fixedly connected to the top of the feed trough 10. The output end of the motor three 11.1 passes through the top of the feed trough 10 and is fixedly connected to the rotating drum 11.2. The stirring blade 11.3 is fixedly connected to the rotating drum 11.2.

[0033] The feed assembly 12 includes a feed hopper 12.1, a solenoid valve 12.2, a feed barrel 12.3, and a cover plate 12.4. The feed barrel 12.3 is fixedly connected to the top of the feed trough 10 and penetrates into the inner cavity of the feed trough 10. The solenoid valve 12.2 is fixedly sleeved on the feed barrel 12.3, the top of the feed barrel 12.3 is fixedly connected to the feed hopper 12.1, and the cover plate 12.4 is clamped on the top of the feed hopper 12.1.

[0034] In a specific application of the embodiment of the present invention, the motor three 11.1 is fixed on the top of the feed trough 10. When the motor three 11.1 is started, it will drive its output end to rotate. Since the output end of the motor three 11.1 passes through the top of the feed trough 10 and is fixedly connected to the drum 11.2, the rotation of the motor three 11.1 will be directly transmitted to the drum 11.2. The drum 11.2 rotates under the drive of the motor three 11.1, and the stirring blade 11.3 fixedly connected to the drum 11.2 also rotates accordingly. Inside the feed trough 10, the rotation of the stirring blade 11.3 can stir the concrete aggregate entering the feed trough 10, so that the aggregate is more evenly distributed in the feed trough 10, ensuring that each part of the aggregate can fully contact the existing moisture or the detection reagent added in the subsequent detection process, etc., laying the foundation for accurate detection of moisture content.

[0035] The feed hopper 12.1 is the entrance for concrete aggregate to enter the equipment, and the cover plate 12.4 on the top plays a sealing role. When feeding is needed, the cover plate 12.4 can be opened to pour the aggregate into the feed hopper 12.1. The existence of the cover plate 12.4 can prevent foreign impurities from entering the feed hopper 12.1 during the operation of the equipment, avoiding interference with the test results, and at the same time can reduce the unnecessary loss of aggregate moisture in the feed hopper 12.1 or the entry of external moisture, ensuring the accuracy of moisture content detection.

[0036] The feed barrel 12.3 is fixedly sleeved with the electromagnetic valve 12.2, and the feed barrel 12.3 penetrates into the inner cavity of the feed trough 10. The electromagnetic valve 12.2 plays a role in controlling the feeding. When the electromagnetic valve 12.2 is opened, the aggregate in the feed hopper 12.1 enters the feed trough 10 through the feed barrel 12.3 under the action of gravity. By controlling the opening and closing of the electromagnetic valve 12.2, the amount of aggregate entering the feed trough 10 can be accurately controlled, which is very important for the accuracy of the subsequent moisture content detection results, because different amounts of aggregate will affect the relative content detection of moisture.

[0037] In a possible embodiment, the constant temperature tube 8.4 is spirally arranged in the side wall of the inner cavity of the detection body 3, and the impurity removal plate 13 is arranged on the side wall of the constant temperature tube 8.4 adjacent to it, the top of the feed box 5 is connected with the bottom of the feed trough 10, and the crushing leaves of the two crushing rollers 6.2 are engaged with each other.

[0038] In a specific application of the embodiment of the present invention, the thermostatic tube 8.4 is spirally arranged in the side wall of the inner cavity of the detection body 3. The spiral arrangement can increase the contact area of ​​the thermostatic tube in the side wall of the detection body. When detecting the moisture content of concrete aggregate, the temperature of the inner cavity of the detection body can be more evenly adjusted by setting the thermostatic tube in a spiral shape. Because for moisture content detection, a stable and appropriate temperature environment is helpful to accurately measure the moisture content in the aggregate. If the temperature fluctuates greatly, related physical processes such as the evaporation rate of moisture will be disturbed, resulting in inaccurate detection results.

[0039] The constant temperature tube can maintain the inner cavity of the detection body at a specific temperature. For example, at a certain temperature, the moisture in the aggregate will evaporate at a relatively stable speed or remain in a stable state, and the moisture content can be accurately detected based on the relevant characteristics of the moisture at this temperature (such as the relationship between the evaporation amount and time, etc.). The impurity removal plate 13 is arranged on the side wall near the constant temperature tube 8.4. During the detection process, when the constant temperature tube adjusts the temperature, it will cause physical or chemical changes in some impurities in the aggregate. The impurity removal plate can use this process to remove impurities. For example, some impurities will become looser or weaken their binding force with the aggregate when the temperature changes. The impurity removal plate can intercept these impurities at this time to prevent them from interfering with the detection of moisture content. At the same time, the stable temperature environment provided by the constant temperature tube also helps the impurity removal plate to play a better role, because the impurity removal efficiency of the impurity removal plate is related to the physical process related to temperature (such as the expansion and contraction of impurities, etc.).

[0040] The top of the feed box 5 is connected with the bottom of the feed trough 10, so that the concrete aggregate can smoothly enter the feed box from the feed trough. The feed trough plays the role of guiding and preliminarily collecting the aggregate. It can concentrate and guide the aggregate from the outside to the feed box, and the feed box plays the role of caching and preliminarily processing the aggregate. For example, the aggregate can be preliminarily mixed or the distribution state of the aggregate can be adjusted in the feed box to better perform moisture content detection later.

[0041] The smooth conveying from the feed trough to the feed box ensures the continuity of the testing process. If there is a blockage or poor conveying in this link, it will affect the working efficiency of the entire testing equipment. In addition, this through-design also helps to control the speed and amount of aggregate entering the testing body, thereby ensuring the accuracy of the test. For example, if the feeding speed is too fast, it will cause uneven distribution of aggregates in the inner cavity of the testing body, affecting the temperature regulation effect of the thermostatic tube, and thus affecting the moisture content test results.

[0042] The crushing blades of the two crushing rollers 6.2 are engaged with each other. Before the moisture content of concrete aggregate is tested, the aggregate needs to be crushed. The crushing blades of the crushing rollers are engaged with each other to achieve more efficient crushing. When the two crushing rollers rotate relative to each other, the engaged crushing blades can cut and crush the aggregate like scissors. This crushing method can crush larger aggregate particles into smaller particles, so that the surface area of ​​the aggregate is increased.

[0043] A larger surface area helps to expose the moisture more fully, thus improving the accuracy of moisture content detection. During the detection process, the moisture evaporates from the surface of the aggregate particles or reacts with the detection reagents. If the aggregate particles are large, the moisture inside cannot fully participate in the detection process, resulting in low test results. After the aggregate is crushed by the crushing roller, its moisture can more fully participate in the physical or chemical processes related to moisture content detection.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0045] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
