Description

Technical Field

[0001] The present application relates to the technical field of material moisture detection equipment, and in particular to a solid powder moisture content measuring device. Background Art

[0002] The moisture content of a substance refers to the proportion of the moisture content in the substance to its total weight. As one of the important characteristics of materials, moisture content plays a vital role in industrial raw material testing, production process testing and product quality control. During the operation of the system, moisture content is not only an important basis for judging the reaction situation, adjusting process parameters, and changing the amount of material added, which directly determines the final result of the reaction and various characteristics of the product, but also participates in the calculation of important interlocking logic, and is closely related to the reliability and stability of the system's automatic control.

[0003] Therefore, only by ensuring the accurate, efficient, continuous and automatic measurement of the moisture content of the material can process control achieve a relatively ideal effect.

[0004] In the current existing technology, there are two ways to measure the moisture content of solid powder:

[0005] The first type is online moisture content measurement, and online moisture content measurement is divided into contact type and non-contact type according to whether the detection equipment is in contact with the solid powder.

[0006] The contact type requires direct contact with the solid powder to be tested. However, when the solid powder in the smoke and dust equipment such as the flue, reactor or pipeline has a high temperature, the detection equipment cannot work normally due to heat resistance limitations. At the same time, because the detection equipment is in direct contact with the solid powder, there is friction and corrosion between the solid powder and the detection equipment, which will cause wear and erosion of the detection equipment in the long run, affecting the service life of the detection equipment. In addition, if the humidity of the solid powder is high, the powder will clump and hang on the detection equipment, seriously affecting the accuracy of the measurement.

[0007] Non-contact type, the detection equipment does not need to be in direct contact with the solid powder to be tested. Therefore, some problems existing in contact measurement can be avoided. However, non-contact type also has some limitations. For example:

[0008] 1. The infrared measurement method is easily affected by the color, dust and moisture of the material and is not universal;

[0009] 2. Non-contact microwave method: The measurement accuracy is greatly affected by the thickness and density of the material.

[0010] Whether it is contact or non-contact detection equipment, it cannot solve the problem of solid powder moisture content detection under the complex working conditions mentioned above. Moreover, when the dust concentration is lower than the detection equipment requirement, the moisture content of the solid powder cannot be detected. In addition, contact or non-contact detection equipment has specific requirements for installation.

[0011] The second is offline moisture content measurement, which is divided into drying method and chemical method. However, no matter whether it is drying method or chemical method, the biggest difficulty in the detection process is the sampling of solid powder.

[0012] Currently, sampling is done manually or by conveyor belts. However, conveyor belt sampling is not suitable for suspended solid powders with relatively low concentrations. Manual sampling is cumbersome and difficult, and subsequent inspection and cleaning operations are usually performed manually, resulting in low measurement efficiency and inability to achieve rapid and continuous measurement.

[0013] Therefore, how to improve the efficiency of measuring the moisture content of solid powders while adapting to complex working conditions is a technical problem that technicians in this field currently need to solve. Summary of the invention

In addition, there is no need for the detection equipment to directly contact the solid powder, that is, there will be no undesirable phenomena of caking, hanging and wear on the detection equipment.

[0056] In summary, the embodiment of the present application provides a solid powder moisture content measuring device, which may include: a fixed component, a sampling tube, a driving component, a measuring device and a heating device. The fixed component is provided in the measuring device to realize a detachable connection with an external unloading device, so that the measuring device can be integrated on the external unloading device for measurement. The automatic sampling and even unloading of solid powders are realized by the cooperation of the driving component and the sampling tube. When the humidity of the solid powder is high, the sampling tube will not be blocked, and the measuring process will not be affected by the external environment. It is suitable for measuring the moisture content of solid powder under different working conditions. In addition, during the measurement process, manual sampling is not required and continuous measurement can be performed, thereby improving the efficiency of the measurement work.

[0057] Optional, please refer to Figure 2 , Figure 2It is a structural schematic diagram of another solid powder moisture content measuring device provided in an embodiment of the present application. The solid powder moisture content measuring device 000 may also include: a sleeve 600 fixedly connected to the fixing component 100, the sleeve 600 may be sleeved on the sampling tube 200, and the sampling tube 200 may be slidably connected to the sleeve 600. The sleeve 600 may have an opening 601, and a flexible joint 602 fixed at the opening 601, and the end of the flexible joint 602 away from the opening 601 in the sleeve 600 may be connected to the feed port 401a in the protective shell 401. Among them, the driving component 300 can be used to drive the sampling tube 200 to move in the sleeve 600, and when the sampling tube 200 is at the target position, it drives the sampling tube 200 to flip so that the sampling port 201 of the sampling tube 200 is connected to the opening 601 of the sleeve 600. In this case, by providing a sleeve 600 in the solid powder moisture content measuring device 000, the sleeve 600 is sleeved on the sampling tube 200 to play a guiding and supporting role for the movement of the sampling tube 200. In addition, a flexible joint 602 is provided between the opening 601 of the sleeve 600 and the feed port 401a of the protective shell 401 for connection, so that the undesirable phenomenon of a large weight measurement error of the measuring device 400 caused by the vibration of the sampling tube 200 and the sleeve 600 can be effectively avoided.

[0058] In the embodiments of the present application, Figure 2 As shown, the driving component 300 in the solid powder moisture content measuring device 000 may include: a flip driving member 301 and a linear driving member 302. One end of the sampling tube 200 may be connected to the flip driving member 301 in a transmission manner, and the linear driving member 302 may be fastened to the end of the flip driving member 301 away from the sampling tube 200. The flip driving member 301 may be used to drive the sampling tube 200 to rotate; the linear driving member 302 may be used to drive the flip driving member 301 and the sampling tube 200 to move simultaneously in a direction close to the external feeding device A, or in a direction away from the external feeding device A. In this case, the flip driving member 301 may drive the sampling tube 200 to rotate, so as to adjust the direction of the sampling port 201 in the sampling tube 200 in the external feeding device A to adapt to different sampling environments, and at the same time, the sampling port 201 in the sampling tube 200 may be driven to align with the opening 601 in the sleeve 600. The linear drive member 302 can drive the flip drive member 301 and the sampling tube 200 to move in a direction close to the external unloading device A to ensure that the sampling tube 200 can sample smoothly, and after the sampling is completed, it can drive the flip drive member 301 and the sampling tube 200 to move in a direction away from the external unloading device A to guide the solid powder in the sampling tube 200 to the measuring component 402 in the protective shell 401.

[0059] For example, the flip driving component 301 may be a servo rotary motor, and the linear driving component 302 may be a linear driving motor or a telescopic cylinder, etc., which is not limited in the embodiment of the present application.

[0060] In this application, please refer to Figure 3 , Figure 3 It is a structural schematic diagram of another solid powder moisture content measuring device provided in an embodiment of the present application. The solid powder moisture content measuring device 000 may also include: a blowpipe device 700, which can be installed at the other end of the sampling tube 200 and is connected to the sampling tube 200. Wherein, when the blowpipe device 700 is in a working state, a preset pressure gas can be introduced into the sampling tube 200 to discharge the solid powder in the sampling tube 200 from the sampling port 201. In this case, by providing the blowpipe device 700 in the solid powder moisture content measuring device 000, a preset pressure gas can be introduced into the sampling tube 200 before collecting the solid powder through the sampling tube 200 to clear the solid powder remaining in the sampling tube 200, thereby ensuring the accuracy of the solid powder moisture content measurement. After the sampling of the sampling tube 200 is completed, after the sampling port 201 in the sampling tube 200 is aligned with the feed port 401a in the protective shell 401, a gas with a preset pressure is introduced into the sampling tube 200 through the blowpipe device 700 to assist the solid powder in the sampling tube 200 to fall more smoothly onto the measuring component 402 in the protective shell 401.

[0061] For example, the blowpipe device 700 may include: a jet pump 701 and a gas pipeline 702 connected to each other, wherein one end of the gas pipeline 702 away from the jet pump 701 may be connected to the sampling tube 200 , and the gas generated by the jet pump 701 is introduced into the sampling tube 200 through the gas pipeline 702 .

[0062] Optional, such as Figure 3 As shown, the bottom of the protective shell 401 may have a discharge port 401b, and the solid powder moisture content measuring device 000 may also include: a cleaning device 800, a drop pipe 900 and a switch valve 1000. The cleaning device 800 may be installed on the side of the protective shell 401 and communicated with the protective shell 401, one end of the drop pipe 900 may be installed at the discharge port 401b, and the other end of the drop pipe 900 may be communicated with the external discharge device A, and the switch valve 1000 may be installed in the drop pipe 900 to control the opening and closing of the drop pipe 900. Among them, when the switch valve 1000 is in the open state, the cleaning device 800 can be used to clean the fixed powder on the measuring component 402, and these solid powders can be introduced into the external discharge device A by the drop pipe 900.

[0063] In this case, by providing a cleaning device 800, a feeding pipe 900 and a switch valve 1000 in the solid powder moisture content measuring device, the cleaning device 800 can clean the solid powder on the measuring component 402 when in operation, and the switch valve 1000 in the feeding pipe 900 is opened so that the solid powder can be introduced into the external feeding device A again, thereby avoiding the waste of solid powder and realizing the automatic cleaning of the measuring device 400. In the process of measuring the weight of solid powder by the measuring device 400, the switch valve 1000 in the feeding pipe 900 is in a closed state, thereby preventing the solid powder on the measuring component 402 from being sucked away under the negative pressure of the external feeding device A.

[0064] Optional, such as Figure 3 As shown, the heating device 500 in the solid powder moisture content measuring device 000 may include: a heat collecting cover 501 and a heating component 502 that are separately arranged, and the heating component 502 may be distributed between the heat collecting cover 501 and the measuring component 402. In this case, by arranging the heat collecting cover 501 and the heating component 502 in the heating device 500, the heat collecting cover 501 can maximize the heat generated by the heating component 502 on the solid powder on the measuring component 402, thereby improving the efficiency of heating and drying the solid powder. For example, the heating component 502 may use a halogen lamp, or those skilled in the art may design other heating devices according to actual needs, which will not be listed one by one in this article.

[0065] In this application, if Figure 3 As shown, the measuring component 402 in the solid powder moisture content measuring device may include: a metering piece 402a and a sample tray 402b connected to each other, and the sample tray 402b may be located between the metering piece 402a and the heating device 500 for carrying solid powder. The solid powder moisture content measuring device 000 may also include: a heat insulating member 1100 fixed in the protective shell 401 and distributed between the metering piece 402a and the sample tray 402b. In this case, the heat insulating member distributed between the sample tray 402b and the metering piece 402a can effectively prevent the heat generated by the heating device 500 from diffusing to the metering piece 402a and causing damage to the metering piece 402a. It should be noted that when the solid powder moisture content measuring device 000 is provided with a cleaning device 800 and a feeding tube 900, the portion of the heat insulating member 1100 staggered with the metering piece 402a may have a feeding hole connected to the feeding tube 900.

[0066] Optional, such as Figure 3As shown, the solid powder moisture content measuring device 000 may further include: a shock absorbing component 1200 connected to the bottom corner of the protective shell 401 and the fixing component 100. In this way, by arranging the shock absorbing component 1200 at the bottom of the protective shell 401, the shock absorbing component 1200 can play a good shock absorbing role on the protective shell 401, thereby preventing the measuring component 402 in the protective shell 401 from shaking during the process of measuring the weight of the solid powder, thereby affecting the measurement accuracy.

[0067] In the examples of this application, please refer to Figure 4 , Figure 4 It is a structural block diagram of a solid powder moisture content measuring device provided in an embodiment of the present application. The solid powder moisture content measuring device 000 may also include: a controller 1300, which may be electrically connected to the measuring component 402 and the heating device 500. Among them, the controller 1300 may be used to record the weight of the solid powder on the measuring component 402 as the initial weight of the sample after the weight of the solid powder measured by the measuring component 402 is not less than the preset sample weight. At the same time, the heating device 500 is controlled to be in an on state, the weight of the dried solid powder is recorded as the end weight, and the moisture content of the solid powder is calculated based on the initial weight and the end weight.

[0068] For example, Figure 4 As shown, the solid powder moisture content measuring device 000 may also include: a timer 1400 and an alarm 1500 electrically connected to the controller 1300, wherein the timer 1400 is used to start after the driving component 300 controls the sampling tube 200 to extend into the external feeding device A, record the actual sampling time, and after the sampling time reaches the preset sampling time, the driving component 300 drives the sampling tube 200 to move to connect the sampling port 201 with the feeding port 401a. The controller 1300 is used to control the alarm 1500 to alarm when the actual sample weight measured by the measuring component 402 is less than the preset sample weight.

[0069] Furthermore, in this embodiment, the timer 1400 is also used to record the heating holding time when the heating device 500 is turned on; the controller 1300 is also used to record the weight of the solid powder at this time as the ending weight when the change in the weight of the solid powder measured by the measuring component 402 is less than a preset value within the preset holding time.

[0070] Optional, such as Figure 3 and Figure 4As shown, the solid powder moisture content measuring device 000 may also include: a temperature detection component 1600 fixed in the protective shell 401, and the temperature detection component 1600 may be used to detect the heating temperature of the heating device 500. In this case, the heating temperature of the heating device 500 can be monitored in real time through the temperature detection component 1600 to avoid burning the measuring component 402 due to excessive temperature. Here, the temperature detection component 1600 and the heating device 500 may be electrically connected to the controller 1300, and the heating device 500 may be controlled to stop heating when the temperature detection component 1600 detects that the temperature of the heating device 500 is high.

[0071] It should be noted that the staff can control the various components in the solid powder moisture content measuring device 100 by operating the controller 1300. For example, the controller 1300 may include a touch screen and a processor, and a human-computer interaction interface may be displayed on the touch screen. The staff can operate on the human-computer interaction interface so that the processor receives the instructions sent by the staff and controls the various components in the solid powder moisture content measuring device according to the received instructions.

[0072] Here, the method of measuring the moisture content of solid powder by the above-mentioned solid powder moisture content measuring device is schematically described:

[0073] (1) Sampling: First, confirm that the switch valve in the feeding tube is in a closed state. The linear drive member drives the flip drive member and the sampling tube to move in a direction close to the external feeding device so as to extend the sampling port of the sampling tube into the external feeding device. After that, after the sampling tube completes sampling, the linear drive member drives the flip drive member and the sampling tube to move in a direction away from the external feeding device, and drives the sampling tube to rotate through the flip drive member so that the sampling port on the sampling tube is connected to the feed port in the protective shell. After that, with the assistance of the blowpipe device, the solid powder in the sampling tube is introduced into the measuring component in the protective shell.

[0074] (2) Measurement: Turn on the measuring component and turn off the heating device, weigh the solid powder on the measuring component, and record the weight of the solid powder at this time as the initial weight.

[0075] After the initial weight measurement is completed, the heating device is turned on. After the heating device is turned on, when the change in the weight of the solid powder measured by the measuring component is less than the preset value, the weight of the solid powder at this time is recorded as the end weight. That is, after the value on the measuring component is stable, the weight of the solid powder at this time is recorded as the end weight.

[0076] After the recording is completed, turn off the measuring device and the heating device. Then use the moisture content calculation formula:

[0077] Solid powder moisture content = (initial weight - final weight) / initial weight

[0078] Calculate the moisture content of the solid powder measured this time.

[0079] (3) Cleaning: Open the switch valve in the drop pipe and start the cleaning device. The solid powder on the measuring component is blown into the drop pipe through the cleaning device, and then introduced into the external discharge equipment through the drop pipe.

[0080] In summary, the embodiment of the present application provides a solid powder moisture content measuring device, which may include: a fixed component, a sampling tube, a driving component, a measuring device and a heating device. The fixed component is provided in the measuring device to realize a detachable connection with an external unloading device, so that the measuring device can be integrated on the external unloading device for measurement. The automatic sampling and even unloading of solid powders are realized by the cooperation of the driving component and the sampling tube. When the humidity of the solid powder is high, the sampling tube will not be blocked, and the measuring process will not be affected by the external environment. It is suitable for measuring the moisture content of solid powder under different working conditions. In addition, during the measurement process, manual sampling is not required and continuous measurement can be performed, thereby improving the efficiency of the measurement work. In addition, there is no need for the detection equipment to directly contact the solid powder, that is, there will be no undesirable phenomena of caking, hanging and wear on the detection equipment.
