Description

Technical Field

[0001] This utility model relates to the field of flour production testing technology, and in particular to an online detection system for the peeling rate of flour mills. Background Technology

[0002] The method for detecting flour scraping rate involves measuring the percentage of wheat material that passes through the coarse sieve after being ground by the bran milling system in flour milling equipment, relative to the flow rate of that bran milling stage. The scraping rate is important because it is one of the key parameters controlling the flour milling process. Measuring and analyzing the scraping rate can guide and correct process operations, ensuring the efficiency and quality of flour milling equipment. Operators need to make comprehensive judgments based on actual conditions (such as raw grain quality and moisture content) and external conditions (such as weather, temperature, and humidity), and make corresponding adjustments.

[0003] Currently, some flour mills rely mainly on manual sampling and testing to monitor flour peeling rate. This poses certain safety risks for operators when taking samples from the flour mill, and multiple samplings are required to calculate the flour peeling rate. Manual sampling is inefficient and cannot provide effective and timely feedback on flour production quality. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing flour mills that rely mainly on manual sampling and testing to monitor flour peeling rate. These shortcomings include safety hazards for operators when taking samples from the flour mill, the need for multiple samplings to calculate the flour peeling rate, low efficiency of manual sampling, and inability to effectively and timely provide feedback on flour production quality. This invention provides an online detection system for flour mill peeling rate.

[0005] The purpose of this utility model is achieved through the following technical solution: an online detection system for the peeling rate of flour mills, including a flour mill discharge pipe, a sampling chamber provided on one side of the flour mill discharge pipe, a movable sampling tube installed in the sampling chamber, an electric push rod installed on one side of the sampling chamber, the telescopic end of the electric push rod extending into the sampling chamber and connecting with the sampling tube, a screening chamber connected to the discharge end of the sampling chamber, a vibrating screen installed in the screening chamber, a first receiving chamber provided below the discharge end of the screened material of the vibrating screen, and a second receiving chamber provided below the discharge end of the residual material of the vibrating screen.

[0006] Both the first and second receiving chambers are equipped with discharge valves. A first weighing sensor is installed at the bottom of the first receiving chamber to measure the weight of the screened material, and a second weighing sensor is installed at the bottom of the second receiving chamber to measure the weight of the sieved residue. An electric push rod drives a sampling tube to collect samples from the flour mill's discharge pipe. The sampled material is then discharged and screened by a vibrating screen to separate the screened material from the residue. The screened material and residue are weighed by the first and second weighing sensors, respectively, and the data is transmitted to an external computing component to calculate the flour stripping rate. This eliminates the need for manual sampling from the mill, improving equipment safety, reducing safety hazards for workers, and increasing sampling efficiency. The real-time calculation of the flour stripping rate using the first and second weighing sensors provides timely feedback on flour production quality, preventing the production of a large number of defective products.

[0007] A further technical solution involves installing a sliding unloading plate on the bottom surface of the sampling tube, and installing a corresponding stop block on the inner bottom wall of the sampling chamber. The stop block is located on one side of the discharge end of the sampling chamber. The bottom surface of the sampling tube has two sets of sliding grooves, and a spring is installed on the side of each groove away from the discharge end of the sampling chamber. A slider connected to the spring is installed in the groove, and the slider is connected to the unloading plate. By setting the unloading plate and the stop block in cooperation, when the electric push rod pushes the sampling tube to extend into the discharge pipe of the flour mill for sampling and then returns it to the sampling chamber, the unloading plate, under the action of the stop block, causes the slider to compress the spring. The unloading plate slides at the bottom of the sampling tube, opening the bottom of the sampling tube and automatically unloading the sample into the sieving chamber. After unloading, the electric push rod drives the sampling tube to reset, and the unloading plate, under the action of the spring and the slider, resets and closes the bottom of the sampling tube for easy sampling next time. This achieves automatic sampling and unloading of the sampling tube, with a simple structure and improved operation convenience.

[0008] A further technical solution is to install an inclined part inside the sampling tube that corresponds to the unloading plate. The inclined part is designed to prevent flour residue inside the sampling tube from causing deviations in the measurement results and to ensure the validity of the measurement.

[0009] A further technical solution is to install a dust cover between the material discharge end of the vibrating screen and the first receiving chamber. By setting up the dust cover, the flour is prevented from being scattered as dust and causing damage to the environment.

[0010] A further technical solution is to install a dust cover between the discharge end of the vibrating screen and the second receiving chamber. By setting up the dust cover, flour dust is prevented from being scattered and causing environmental damage.

[0011] A further technical solution is to install an inclined discharge pipe at the lower part of the flour mill's discharge pipe, with the discharge ends of the first and second receiving chambers respectively connected to the inclined discharge pipe. By setting the discharge ends of the first and second receiving chambers to be connected to the inclined discharge pipe respectively, the measured flour can be recycled, facilitating the next sampling and analysis, while avoiding waste of flour.

[0012] This invention has the following advantages: It uses an electric push rod to drive a sampling tube to take samples from the flour mill's discharge pipe. The sampled material is then discharged through a vibrating screen to separate the screened material and the residue. The screened material and residue are weighed by a first and a second weighing sensor, respectively, and the data is transmitted to an external computing component to calculate the flour's peeling rate. This avoids manual sampling from the mill, improving equipment safety, reducing safety hazards for workers, and increasing sampling efficiency. The real-time calculation of the flour peeling rate using the first and second weighing sensors provides timely feedback on flour production quality, preventing the production of a large number of defective products.

[0023] like Figures 1-3 As shown, the online detection system for the peeling rate of a flour mill includes a flour mill discharge pipe 1, a sampling chamber 2 on one side of the flour mill discharge pipe 1, a movable sampling tube 3 installed in the sampling chamber 2, an electric push rod 4 installed on one side of the sampling chamber 2, the telescopic end of the electric push rod 4 extending into the sampling chamber 2 and connected to the sampling tube 3, a screening chamber 7 connected to the discharge end of the sampling chamber 2, a vibrating screen 8 installed in the screening chamber 7, a first receiving chamber 9 below the discharge end of the screened material of the vibrating screen 8, and a second receiving chamber 10 below the discharge end of the residual material of the vibrating screen 8.

[0024] Both the first receiving chamber 9 and the second receiving chamber 10 are equipped with discharge valves 11. A first weighing sensor 12 is installed at the bottom of the first receiving chamber 9 to measure the weight of the screened material inside the first receiving chamber 9. A second weighing sensor 13 is installed at the bottom of the second receiving chamber 10 to measure the weight of the sieved residue inside the second receiving chamber 10. An electric push rod 4 drives the sampling tube 3 to take a sample from the discharge pipe 1 of the flour mill. The sampled material is then discharged and screened by a vibrating screen 8 to separate the screened material and the sieved residue. The screened material and the sieved residue are weighed by the first weighing sensor 12 and the second weighing sensor 13, respectively, and the data is transmitted to an external computing component to calculate the flour peeling rate. This avoids manual sampling from the mill, improves equipment safety, reduces safety hazards for workers, and improves sampling efficiency. The flour peeling rate is calculated in real time by weighing the data from the first weighing sensor 12 and the second weighing sensor 13, which can provide timely feedback on the flour production quality and avoid the production of a large number of defective products.

[0025] A further technical solution is that a slidable unloading plate 5 is installed on the bottom surface of the sampling tube 3, and a stop block 6 corresponding to the unloading plate 5 is installed on the inner bottom wall of the sampling chamber 2. The stop block 6 is located on one side of the discharge end of the sampling chamber 2. Two sets of sliding grooves 16 are provided on the bottom surface of the sampling tube 3. A spring 17 is installed on the side of each sliding groove 16 away from the discharge end of the sampling chamber 2. A slider 18 connected to the spring 17 is installed in the sliding groove 16. The slider 18 is connected to the unloading plate 5. By setting the unloading plate 5 and the stop block 6 in cooperation, the sampling tube 3 can be pushed by the electric push rod 4. When the sample is taken from the discharge pipe 1 of the flour mill and then returned to the sampling chamber 2, the unloading plate 5, under the action of the stop block 6, causes the slider 18 to compress the spring 17. The unloading plate 5 slides at the bottom of the sampling tube 3, opening the bottom of the sampling tube 3, so that the sample in the sampling tube 3 is automatically unloaded into the sieving chamber 7. After the unloading is completed, the electric push rod 4 drives the sampling tube 3 to reset. The unloading plate 5, under the action of the spring 17 and the slider 18, resets and closes the bottom of the sampling tube 3 to facilitate the next sampling. Thus, the automatic sampling and unloading of the sampling tube 3 is realized. The structure is simple and the convenience of operation is improved.

[0026] A further technical solution is to install an inclined part 15 inside the sampling tube 3 that corresponds to the unloading plate 5. The inclined part 15 is set to avoid the measurement results being deviated due to flour residue inside the sampling tube 3, thus ensuring the validity of the measurement.

[0027] A further technical solution is to install a dust cover 19 between the material discharge end of the vibrating screen 8 and the first receiving chamber 9. By setting up the dust cover 19, the flour dust is prevented from being scattered and causing damage to the environment.

[0028] A further technical solution is to install a dust cover 19 between the discharge end of the screen residue of the vibrating screen 8 and the second receiving chamber 10. By setting up the dust cover 19, the flour dust is prevented from being scattered and causing damage to the environment.

[0029] A further technical solution is that an inclined discharge pipe 14 is installed at the lower part of the discharge pipe 1 of the flour mill. The discharge ends of the first receiving chamber 9 and the second receiving chamber 10 are respectively connected to the inclined discharge pipe 14. By setting the discharge ends of the first receiving chamber 9 and the second receiving chamber 10 to be respectively connected to the inclined discharge pipe 14, the measured flour can be recycled, which is convenient for the next sampling and analysis, and at the same time avoids the waste of flour.

[0030] The working process of this utility model is as follows: When using this system to detect the peeling rate, firstly, the electric push rod 4 pushes the sampling tube 3 into the discharge pipe 1 of the flour mill to take a sample. The upper part of the sampling tube 3 is open. After the flour falls into the sampling tube 3, the electric push rod 4 drives the sampling tube 3 back into the sampling chamber 2. Under the blocking action of the bottom wall baffle 6 in the sampling chamber 2, the unloading plate 5 slides along the bottom surface of the sampling tube 3 through the compression spring 17 via the slider 18. At this time, the bottom surface of the sampling tube 3 opens and unloads the sample onto the vibrating screen 8 in the sieving chamber 7. The vibrating screen 8... The sample is vibrated and screened. The screened material falls into the first receiving chamber 9 at the bottom of the vibrating screen 8, while the residual material falls into the second receiving chamber 10. The first weighing sensor 12 weighs the screened material in the first receiving chamber 9, and the second weighing sensor 13 weighs the residual material in the second receiving chamber 10. The first weighing sensor 12 and the second weighing sensor 13 send the measurement data to an external computing component for calculation. The flour peeling rate is: weight of screened material / (weight of screened material + weight of residual material), which can obtain the flour peeling rate in a timely manner.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
