Description

Technical Field

[0001] The invention relates to the technical field of industrial automation instruments, in particular to a solid flow meter. Background Art

[0002] A solid flow meter is an instrument used to monitor and measure the flow of solid materials such as powders, granules or bulk materials. It is mainly used in industrial process control, quality assurance, inventory management and scientific research. The technology and application fields of solid flow meters are constantly expanding, and their types and functions are also increasing.

[0003] However, during the use of the existing solid flow meter, the solid flow tube will be offset due to external factors, causing the microwave sensor to be unable to maintain a horizontal state with the side wall of the solid flow tube, and the solid will hit the microwave sensor multiple times during the falling process, causing the microwave sensor to shift. When the microwave sensor is not horizontal with the solid flow tube, the reflection path of the microwave signal may change, resulting in deviations in the received signal strength, phase or frequency parameters, making the originally simple signal analysis process complicated, because it is necessary to additionally consider the signal changes caused by the installation angle, thereby increasing the complexity and calculation amount of the signal processing circuit, resulting in the measurement of There is a deviation between the measured distance and the actual distance, which affects the accuracy of the monitoring results. If the installation state is not level for a long time, the internal mechanical structure of the microwave sensor may be aggravated, thus affecting its service life and stability. In addition, when this equipment detects solids in non-metallic pipes, the microwaves generated by the microwave sensor will penetrate the pipe and detect floating objects such as dust outside the pipe, resulting in a deviation between the detected data and the actual data. If the pipe diameter is too large, the reflected wave farthest from the microwave sensor will become worse, resulting in the microwave sensor being unable to receive the reflected wave of the distant solid in time, thereby reducing the detection accuracy of the microwave sensor and affecting its use effect.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] In a typical implementation of this application, please refer to Figures 1 to 13As shown, a solid flow meter includes a solid flow pipe 1, the solid flow pipe 1 is used for the circulation of solids, the top and bottom surfaces of the solid flow pipe 1 are fixedly mounted with flanges 2, and the flanges 2 are used to connect the device with a pipeline to be detected; The detection component is arranged on the solid flow pipe 1 and is used to detect the flow rate of the solid inside the solid flow pipe 1. The detection component includes: The circular tube 3 is arranged on one side of the solid flow tube 1, the top and bottom surfaces of the circular tube 3 are fixedly mounted with support rods 4, the left side of the support rods 4 is fixedly connected to the outer surface of the solid flow tube 1, and the left side wall of the circular tube 3 is mounted with a microwave sensor 6 through an offset adjustment member, and the left side of the microwave sensor 6 is located inside the solid flow tube 1; The housing 14 is fixedly mounted on the right side wall of the circular tube 3. A display 15 is fixedly mounted on the top surface of the housing 14. A control button 16 is arranged on one side of the display 15. A cavity 17 is provided on the front side of the housing 14. Limiting grooves 18 are provided on the left and right sides of the inner wall of the cavity 17. A protection mechanism, which is disposed on the housing 14 and is used to protect the non-metallic pipeline during detection; A sealing assembly, which is disposed on the housing 14 and is used to seal the cavity 17; When solids are detected, the solids flow through the solid flow pipe 1 by free fall or other means such as pneumatics. The staff can turn on the microwave sensor 6 by operating the button 16, so that the microwave sensor 6 generates a microwave field in the pipe. The microwaves are reflected by the solids flowing in the solid flow pipe 1, and the changes in the frequency and amplitude of the reflected microwaves are calculated, and then the flow rate of the solids is accurately displayed on the display 15. The above process is the basic flow of fixed flow detection.

[0018] However, during use, the solid flow tube 1 may be offset due to external factors, causing the microwave sensor 6 to be unable to maintain a horizontal state with the side wall of the solid flow tube 1, and the solid may hit the microwave sensor 6 multiple times during the falling process, causing the microwave sensor 6 to be offset. When the microwave sensor 6 is not horizontal with the solid flow tube 1, the reflection path of the microwave signal may change, resulting in deviations in parameters such as the received signal strength, phase or frequency, making the originally simple signal analysis process complicated, because it is necessary to additionally consider the signal changes caused by the installation angle, thereby increasing the complexity and calculation amount of the signal processing circuit, resulting in a deviation between the measured distance and the actual distance, affecting the accuracy of the detection result. If the installation state is not level for a long time, the internal mechanical structure of the microwave sensor 6 may be aggravated, thereby affecting its service life and stability. In addition, when the device detects solids in a non-metallic pipe, the microwaves generated by the microwave sensor 6 will penetrate the pipe and detect floating objects such as dust outside the pipe, causing the detected data to deviate from the actual data. If the pipe diameter is too large, the reflected wave farthest from the microwave sensor 6 will become worse, causing the microwave sensor 6 to be unable to receive the reflected wave from the distant solid in time, thereby reducing the detection accuracy of the microwave sensor 6 and affecting its use effect.

[0019] Therefore, based on the above problems, we first design an offset adjustment member as a preferred implementation in this embodiment. Figures 1 to 8 As shown, the offset adjustment member includes: a protective shell 7, the protective shell 7 is fixedly mounted on the top surface of one of the support rods 4, a gyroscope body 8 is fixedly mounted inside the protective shell 7, a gyroscope sensor 9 is fixedly mounted on the inner wall of the protective shell 7 located on one side of the gyroscope body 8, and a transmission line 10 is arranged on the top surface of the gyroscope sensor 9, and the offset adjustment member also includes: an iron ball 5, the iron ball 5 is movably connected to the inside of the circular tube 3, the left side wall of the iron ball 5 is fixedly connected to the right side wall of the microwave sensor 6, a processor 11 is fixedly mounted inside the circular tube 3, one end of the transmission line 10 is connected to the gyroscope sensor 9, and the other end is connected to the processor 11, a plurality of electromagnets 12 are fixedly mounted on the inner wall of the circular tube 3 located around the iron ball 5, and a control line 13 is arranged between the electromagnet 12 and the processor 11; According to the above features, when the solid flow tube 1 or the microwave sensor 6 is offset, the gyroscope body 8 in the protective shell 7 will also be synchronously offset. At this time, the gyroscope sensor 9 on one side will transmit the offset angle of the gyroscope body 8 to the processor 11 through the transmission line 10. The processor 11 will process the data transmitted by the gyroscope sensor 9 in a timely manner, and calculate the offset angle of the solid flow tube 1 or the microwave sensor 6. The processor 11 then turns on the electromagnet 12 through the control line 13 to adjust the iron ball 5. Since the microwave sensor 6 is fixedly connected to the outer surface of the iron ball 5, the microwave sensor 6 will be synchronously adjusted when the iron ball 5 is adjusted. When the solid flow tube 1 is offset, the microwave sensor 6 will be adjusted to a position flush with the solid flow tube 1. If the microwave sensor 6 is offset, the microwave sensor 6 will be restored to a position flush with the solid flow tube 1. It is worth mentioning that to realize the control of the electromagnet 12 by the processor 11, it is only necessary to set one or more thresholds in the processor 11 to determine whether the electromagnet 12 needs to be turned on. These thresholds can be set according to the specific application scenario, such as the rotation angle, rotation speed or rotation direction of the gyroscope body 8. The processor 11 compares the processed data of the gyroscope body 8 with the set threshold. If the conditions for turning on the electromagnet 12 are met, such as reaching or exceeding a certain angle, speed, etc., the next step is executed, and the control circuit 13 sends a control signal to the control circuit of the electromagnet 12 to turn on the electromagnet 12. This is an existing mature technical means, and therefore, it will not be described in detail in the present invention.

[0020] Based on the above problems, we also designed a protection mechanism as a preferred implementation in this embodiment, please refer to Figure 5 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, the protection mechanism includes: two sliders 19, the two sliders 19 are slidably installed in the limit grooves 18 respectively, a rotating rod 20 is rotatably connected between the two sliders 19, both ends of the outer surface of the rotating rod 20 are rotatably connected to rings 21, a concave rod 22 is fixedly installed between the two rings 21, a metal iron sheet 23 is arranged on the rotating rod 20, and a reflector 30 is arranged on the side of the metal iron sheet 23 facing the solid flow pipe 1, and the protection mechanism also includes a push rotation component and an adjustment component; As a preferred implementation in this embodiment, please refer to Fig. 9 , Fig.10 ,and Fig.12 As shown, the push-rotating assembly includes: an electric push rod 24, which is fixedly mounted on the inner wall of the cavity 17, a push block 25 is fixedly mounted on the output end of the electric push rod 24, a mounting groove 26 is provided on the front side wall of the push block 25, a motor 27 is fixedly mounted inside the mounting groove 26, and the output shaft of the motor 27 is rotatably connected to the rear side wall of the concave rod 22; As a preferred implementation in this embodiment, please refer to Figure 5 and Fig.11 As shown, the adjustment component includes: two moving buttons 31, the two moving buttons 31 are respectively arranged on the surface of the metal iron sheet 23 away from the solid flow pipe 1, the outer surface of the metal iron sheet 23 is provided with two moving grooves 32, the inside of the two moving grooves 32 are both provided with a corrugated hose 33, one end of the corrugated hose 33 is connected to the moving button 31, and the other end is connected to the reflector 30; A second mounting groove 34 is provided on the left side wall of one of the sliders 19, a second motor 35 is fixedly installed inside the second mounting groove 34, the output shaft of the second motor 35 is connected to the side wall of the rotating rod 20, an unlocking button 28 is fixedly installed on the rear side wall of the housing 14, a locking tongue 29 is fixedly installed on the side wall of the metal iron sheet 23, and the locking tongue 29 cooperates with the unlocking button 28; Through the above features, when encountering a non-metallic pipeline that needs to detect the solid flow rate, or detecting the solid flow rate in an oversized pipeline, the staff opens the sealing assembly, and then turns on the electric push rod 24 through the control button 16, so that the electric push rod 24 pushes the push block 25, and the push block 25 pushes the concave rod 22, so that the two sliders 19 drive the metal iron sheet 23 located on the outer surface of the rotating rod 20 to slide on the limit groove 18 and slide out of the cavity 17, and then turns on the motor 1 27 through the control button 16 to rotate the concave rod 22 connected to the output shaft of the motor 1 27 ninety degrees. When the concave rod 22 rotates ninety degrees, the ring 21 connected to the concave rod 22 will drive the rotating rod 20 to rotate synchronously, and the metal iron sheet 23 located on the rotating rod 20 is perpendicular to the bottom surface. At this time, the staff only needs to pull the locking tongue 29 on one side of the metal iron sheet 23 to wrap the solid flow pipe 1 on one side of the microwave sensor 6, and then engage the locking tongue 29 with the unlocking button 28 to make the microwave sensor 6 When the microwave sensor 6 detects non-metallic pipes, it will not detect floating objects such as dust in the air. When detecting an oversized pipe, it only needs to move the rotating rod 20 in the moving groove 32 to the opposite surface of the microwave sensor 6 through the moving button 31 and the corrugated hose 33, so as to strengthen the solid reflection wave farthest from the microwave sensor 6, so that the microwave sensor 6 can receive the fixed reflection wave in time, thereby increasing the accuracy of the detection. When the metal iron sheet 23 is not needed, it only needs to press the unlocking button 28 to make the lock tongue 29 disengage from the card of the unlocking button 28, and then the staff turns on the motor 2 35 through the operating button 16 to rotate the rotating rod 20, so that the metal iron sheet 23 is rolled up on the rotating rod 20, and then the motor 1 27 is started by the operating button 16 to make the slider 19 and the rotating rod 20 rotate synchronously, so that the control circuit 13 is parallel to the ground, and then the electric push rod 24 is retracted to control the circuit 13 to be collected into the cavity 17 for protection; It is worth mentioning that the metal iron sheet 23 , the reflective plate 30 , the movable button 31 , the movable slot 32 and the corrugated hose 33 are all made of a retractable material, and the end of the metal iron sheet 23 is fixedly connected to the outer surface of the rotating rod 20 .

[0021] As a preferred implementation in this embodiment, please refer to Figure 5 and Fig. 9As shown, the sealing assembly includes: a sealing plate 36, the sealing plate 36 is arranged on the housing 14, and limit blocks 37 are fixedly installed on both side walls of the sealing plate 36, and the two limit blocks 37 slide on the limit grooves 18 respectively, and a rectangular magnet 38 is fixedly installed on the top surface of the cavity 17, and a rectangular groove 39 is opened on the top surface of the sealing plate 36, and the rectangular magnet 38 and the rectangular groove 39 cooperate with each other; Through the above-mentioned features, when the protective mechanism is not in use, the staff uses the handle to slide the sealing plate 36 on the limiting groove 18 through the limiting blocks 37 on both sides, so that the sealing plate 36 seals the cavity 17. When pushed to a certain position, the rectangular magnet 38 and the rectangular groove 39 are engaged and attracted to each other to complete the sealing, so that it protects the protective mechanism. When the protective mechanism needs to be used, the staff only needs to pull out the sealing plate 36 by the handle.

[0022] Working principle: When in use, first connect the solid flow meter to the pipeline to be detected through the flange 2. The staff can turn on the microwave sensor 6 by operating the button 16, so that the microwave sensor 6 generates a microwave field in the pipeline. When the solid passes through the solid flow pipe 1, its flow will reflect the microwave. After receiving these reflected waves, the microwave sensor 6 calculates the changes in the frequency and amplitude of the reflected microwave, thereby accurately displaying the solid flow rate and displaying it through the display 15. This is the basic process of fixed flow detection. However, in actual application, the solid flow pipe 1 may be offset due to external factors, resulting in the microwave sensor 6 being unable to maintain a horizontal state with the side wall of the solid flow pipe 1. At this time, the gyroscope body 8 is synchronously offset and sends the offset data to the processor 11 through the transmission line 10. The processor 11 analyzes the data and calculates the offset angle, and then activates the electromagnet 12 through the control line 13 to adjust the position of the iron ball 5, and then adjusts the angle of the microwave sensor 6 to ensure that it always remains horizontal with the side wall of the solid flow pipe 1. This The process effectively avoids the detection error caused by the change of the signal path and ensures the accuracy of the measurement. For the detection of non-metallic pipes or the situation that the pipe diameter is too large, the device is also designed with a protective mechanism. When non-metallic pipe detection is required, the staff starts the electric push rod 24 by operating the button 16, pushes the push block 25 and the concave rod 22, and makes the metal iron sheet 23 slide out of the shell 14. Then, the motor 1 27 is started to rotate the concave rod 22 by ninety degrees, and the metal iron sheet 23 is vertically unfolded. The staff can fix the metal iron sheet 23 around the pipe by pulling the lock tongue 29, and use it with the reflector 30 to prevent the microwave sensor 6 from erroneously detecting floating objects in the air, and strengthen the reception of reflected waves of long-distance solids to improve the detection accuracy. When not in use, the metal iron sheet 23 is retracted into the shell 14 through the reverse operation of the motor 2 35 and the electric push rod 24, and is protected by the sealing component. The design of the sealing component is to protect the internal mechanical structure from the external environment when the protective mechanism is not in use. By sliding the sealing plate 36, rapid sealing is achieved by utilizing the magnetic attraction between the rectangular magnet 38 and the rectangular groove 39, thereby ensuring the stability and service life of the equipment.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
