[0047] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0048] In order to solve the technical problem of long time consumption in the process of measuring material density, the present application provides the following embodiments to solve the above problem:

[0049] This embodiment provides a material density detection device, such as Figure 1 As shown, it is a structural diagram of the device of this embodiment. The device of this embodiment may specifically include: a metering module 11 and a control module 10;

[0050] The metering module includes a metering container 111, a liquid level sensor 112 and a weighing module 113;

[0051] The measuring container 111 is used to contain the material to be measured;

[0052] The liquid level sensor 112 is arranged at the material inlet of the measuring container, and is used to measure the liquid level height value of the material to be measured in the measuring container 111;

[0053] The weighing module 113 is used to measure the weight value of the measuring container 111 containing the material to be measured;

[0054] The control module 10 is used to obtain the liquid level height value and the weight value of the measuring container, obtain the volume of the material to be measured according to the liquid level height value and the set volume calculation method, and obtain the density of the material to be measured according to the volume and weight values.

[0055] In a possible embodiment, the metering container in the material density detection device can contain the material to be tested, and the control module can read the liquid level height value of the material to be tested obtained by the liquid level sensor fixed at the feed inlet. The control module can also obtain the weight value of the metering container containing the material to be tested weighed by the weighing module, and subtract the preset weight value of the metering container to determine the weight value of the material to be tested. The control module can also determine the volume of the material to be tested according to the liquid level height value, and calculate the density value of the material to be tested by combining the volume and weight value of the material to be tested. The set calculation method includes: a calculation method for calculating the weight value of the material to be tested according to the weight value of the metering container containing the material to be tested; a calculation method for determining the volume of the material to be tested according to the liquid level height value, and a calculation method for determining the density of the material to be tested according to the volume and weight value.

[0056] When the material density detection device of this embodiment is used, when the material to be tested is contained in the measuring container, the liquid level sensor and the weighing module can be used to quickly obtain parameters related to the material to be tested, and the density value can be calculated directly according to the preset calculation method, which greatly shortens the time for obtaining the density of the material to be tested.

[0057] In a possible embodiment, the material density detection device further includes a sampling buffer 12, the sampling buffer includes a buffer body 121, and the buffer body 121 is provided with an inlet pipe 1211 and a discharge pipe 1212. The material to be tested enters the buffer body from the inlet pipe 1211, and enters the metering container 111 after being discharged from the discharge pipe 1212;

[0058] The discharge pipe 1212 is located above the feed inlet of the metering container 111, and the diameter of the end of the discharge pipe close to the feed inlet is smaller than the diameter of the feed inlet.

[0059] In the process of injecting the material to be tested into the metering container, the material to be tested can be directly injected into the metering container through the sampling pipe. The material to be tested can be directly injected into the metering container from the sampling pipe, or it can be injected into the metering container through the discharge pipe of the sampling buffer after being buffered by the sampling buffer. When the material to be tested is injected into the metering container through the sampling buffer, since the discharge pipe of the sampling buffer is located above the feed port of the metering container, and the diameter of the end of the discharge pipe close to the feed port is smaller than the diameter of the feed port, the sampling buffer can smoothly transport the material to be tested to the metering container, avoiding the loss of the material to be tested due to excessively high flow rate, and ensuring the accuracy of the final density.

[0060] In a possible embodiment, the material density detection device further includes a sampling water injection module 13, the water injection module 13 includes a first water inlet pipeline 131 and a second water inlet pipeline 132 connected to each other, one end of the first water inlet pipeline 131 away from the second water inlet pipeline 132 is connected to the feed pipe 1211, and one end of the second water inlet pipeline 132 away from the first water inlet pipeline 131 is connected to the bottom of the buffer body 121; the water injection module injects water into the measuring container 111 through the first water inlet pipeline 131 or the second water inlet pipeline 132. .

[0061] The water injection module can inject water into the metering container. The water injected by the water injection module can be used as cleaning water for cleaning the metering container and the sampling buffer. The water injected by the water injection module can also be used as supplementary water. When the metering container contains the material to be tested, the supplementary water can increase the liquid level value of the material to be tested. In addition, the volume or mass of the water injected by the water injection module can be known.

[0062] When the water injected by the water injection module is cleaning water, the water injection module can inject the water into the buffer body and the metering module through the feed pipe of the buffer body.

[0063] When the water injected by the water injection module is supplementary water, the water injection module can inject the water into the metering module through the bottom of the buffer body.

[0064] The water injection module may also be provided with a first valve and a second valve, the first valve being used to start and stop the first water inlet pipeline, and the second valve being used to start and stop the second water inlet pipeline. When the water injected by the water injection module is used as cleaning water, the first valve is activated, and the water injection module can inject water through the first water inlet pipeline; when the water injected by the water injection module is used as cleaning water, the second valve is activated, and the water injection module can inject water through the second water inlet pipeline.

[0065] In a possible embodiment, the weighing module 113 includes a weighing bracket 1131 and a weighing sensor 1132;

[0066] The weighing bracket 1131 is used to fix the measuring container;

[0067] The weighing sensor 1132 is used to obtain the weight value of the material to be measured contained in the measuring container.

[0068] In order to accurately obtain the weight value of the material to be measured, the weighing module is provided with a weighing bracket and a weighing sensor. The weighing bracket can fix and clamp the measuring container so that the weight value obtained by the weighing sensor can be close to the actual weight value of the measuring container containing the material to be measured.

[0069] This embodiment provides a material density detection method, such as Figure 2 FIG. 1 is a flow chart of the method of this embodiment. The method of this embodiment is executed in the control module of the material density detection device, and may specifically include:

[0070] Step 201 , obtaining a liquid level value of the material to be measured in the measuring container sent by a liquid level sensor, and a weight value of the measuring container containing the material to be measured sent by a weighing module.

[0071] like Figure 1 As shown, a liquid level sensor 2 can be provided in the metering container, and the liquid level sensor is provided at the bottom of the metering container. When the material to be tested is injected into the metering container, the liquid level sensor can be triggered, and the liquid level sensor sends injection information to the control module. The control module can respond to the injection information and obtain the liquid level height value of the material to be tested in the metering container by using the liquid level sensor at the feed inlet of the metering container.

[0072] In this embodiment, the liquid level height value represents the height value of the material to be tested after the material to be tested is injected into the metering container. During the process of injecting the material to be tested into the metering container, the injection time and injection flow rate can be a preset time length and a preset flow rate, and the injected material to be tested does not exceed the maximum volume that the metering container can accommodate.

[0073] After the injection of the material to be measured is completed, the liquid level height value measured by the liquid level sensor arranged in the measuring container is the liquid level height value of the material to be measured.

[0074] The control module can use the weighing module to obtain the weight value of the measuring container. The weighing module can first weigh and obtain the weight value of the measuring container when it does not contain the material to be measured. After the measuring container contains the material to be measured, the weighing module obtains the weight value of the measuring container when it contains the material to be measured. The control module obtains the two weight values ​​and calculates the difference to obtain the weight value of the material to be measured.

[0075] In addition, when water is injected into the material to be tested, the control module calculates the mass of the injected water according to the volume of the injected water, and further subtracts the mass of the injected water to obtain the weight value of the material to be tested.

[0076] Step 202, the volume of the material to be tested is obtained according to the liquid level value and the set volume calculation method, and the density of the material to be tested is obtained according to the volume and weight values.

[0077] After determining the liquid level value, the control module can calculate the volume of the material to be tested according to the relationship between the liquid level value and the volume. In other words, there is a corresponding relationship between the liquid level value and the volume. After determining the liquid level value of the material to be tested, the control module can directly determine the volume of the material to be tested.

[0078] In a possible embodiment, the volume of the material to be tested may be calculated in the following manner:

[0079] Obtain the initial liquid level height value of the material to be measured in the metering container sent by the liquid level sensor; determine whether the initial liquid level height value reaches the measurable liquid level height value range, the measurable liquid level height value range represents the liquid level height that can calculate the volume of the material to be measured; if the initial liquid level height value is less than the lower limit value of the measurable liquid level height value range, control the water injection module to inject water into the metering container until the liquid level height value of the material to be measured is at least greater than the lower limit value of the measurable liquid level height value range; obtain the liquid level height value of the material to be measured in the metering container after water injection sent by the liquid level sensor.

[0080] In the content of this embodiment, since the volume of the material to be measured in the metering container may not be uniform during each measurement process, when the metering container is an irregularly shaped container, different volumes of the material to be measured correspond to different liquid level heights. Under different liquid level heights, the volume calculation methods of the material to be measured are quite different. Therefore, in order to realize the rapid calculation of the volume of the material to be measured, in the content of this embodiment, the control module can perform rapid volume calculation for the material to be measured whose liquid level height is within the measurable liquid level height value range. For example, a unified calculation formula can be provided, and the volume of the material to be measured can be quickly obtained by substituting the liquid level height value. When the liquid level height of the material to be measured is less than the lower limit value of the measurable liquid level height value range, water is injected into the material to be measured until the liquid level height of the material to be measured after the water injection is greater than the lower limit value of the measurable liquid level height value range. When the liquid level height value of the material to be measured after the water injection is within the measurable liquid level height value range, the control module performs a rapid calculation of the volume of the material to be measured after the water injection. After obtaining the volume of the material to be tested after water injection, since the volume of the injected water is known, the actual volume of the material to be tested is obtained by subtracting the volume of the injected water.

[0081] In a possible embodiment, the volume of the material to be measured is determined by using the liquid level height value, including:

[0082] The maximum volume and maximum liquid level value of the measuring container are obtained, wherein the maximum liquid level value indicates the upper limit of the measurable liquid level value range; the volume difference is calculated based on the liquid level difference between the maximum liquid level value and the liquid level value, combined with the horizontal cross-sectional area of ​​the feeding pipe of the measuring container; the volume of the material to be measured is determined by using the difference between the maximum volume and the volume difference.

[0083] The maximum volume refers to the maximum volume of material that the measuring container can accommodate. The maximum liquid level value refers to the highest liquid level that the material in the measuring container can reach, that is, the upper limit of the measurable liquid level value range. The maximum volume and the maximum liquid level value are in a corresponding relationship. On the basis of determining the maximum volume, the volume difference can be determined according to the liquid level difference, and the actual material volume can be further determined.

[0084] Specifically, in the process of calculating the volume difference, the calculation can be performed based on the actual structure of the measuring container. In the present embodiment, when the control module calculates the volume of the material to be measured, the material to be measured in the measuring container needs to reach a certain liquid level. This calculation method is applicable to measuring containers with regular shapes in some structures.

[0085] For example, Figure 3The figure shows the main view of the measuring container. The measuring container is cylindrical from end a to end b, and end a is the highest point. When end a to end b is the measurable liquid level height range, end a is the upper limit, which is also the maximum liquid level height value, and end b is the lower limit. In the process of obtaining the maximum volume, the material can be pre-filled in the measuring container to end a, and the volume of the contained material can be measured to determine the maximum volume corresponding to end a of the measuring container.

[0086] When the liquid level of the material to be measured is between end a and end b, calculate the height difference between the liquid level and end a, and combine the horizontal cross-sectional area of ​​the cylinder from end a to end b, according to:

[0087] V=V0-π(D / 2)2(h-h0) (1)

[0088] Calculate the volume of the material to be measured, where V0 is the maximum volume of the measuring container, D represents the horizontal cross-sectional area, h represents the liquid level height difference, and h0 represents the liquid level height value of the material to be measured.

[0089] In a possible embodiment, the volume of the material to be measured is determined by using the liquid level height value, including:

[0090] Determine the liquid level segment to be measured where the liquid level height value is located, wherein the measuring container includes multiple liquid level segments, and each liquid level segment corresponds to a volume calculation model; obtain the target volume calculation model corresponding to the liquid level segment to be measured; and determine the volume of the material to be measured according to the target volume calculation model and the liquid level height value.

[0091] In the process of determining the volume of the material to be measured according to the liquid level height value, since the liquid level height value is known, in order to facilitate the calculation of the volume, it can be directly substituted into the relevant calculation formula or calculation model to realize the calculation of the volume of the material to be measured.

[0092] For example, the structure of the measuring container can be divided into multiple liquid level sections. Figure 4 As shown, the measuring container of this structure can be divided into liquid level section 41, liquid level section 42, liquid level section 43, liquid level section 44 and liquid level section 45. Among them, different liquid level sections can correspond to different material volume calculation methods, among which, liquid level section 41, liquid level section 43 and liquid level section 45 correspond to the volume calculation method of cylinder, and liquid level section 42 and liquid level section 44 correspond to the volume calculation method of cone.

[0093] In addition, the liquid level segments 41 to 45 are arranged in a vertical order from low to high. After calculating the volume corresponding to the liquid level segment using the liquid level height value, it is also necessary to accumulate the volume of the liquid level segment whose vertical height is lower than that of the liquid level segment. For example, when the liquid level height value belongs to liquid level segment 43, in addition to calculating the volume in liquid level segment 43, it is also necessary to accumulate the total volume in liquid level segments 41 and 42 to determine the volume of the material to be measured.

[0094] After determining the volume and weight of the material to be tested, according to the formula:

[0095] ρ=M0 / V (2)

[0096] To obtain the density of the material to be tested, ρ represents the density of the material to be tested, M0 represents the weight of the material to be tested, and V represents the volume of the material to be tested.

[0097] By using the material density detection device provided in this embodiment, the material to be tested can be placed in a measuring container, and the density value of the material to be tested can be calculated based on the liquid level height value and weight value of the material to be tested directly obtained, without the need to perform other processes, thereby greatly shortening the calculation process of the material density and reducing the time taken to obtain the material density.
