Description

Technical Field

[0001] This utility model relates to the field of material level measurement technology, specifically a material level measurement device for cement silos. Background Technology

[0002] In the cement production process, from raw material mining and processing to the storage and packaging of finished cement, accurate material level monitoring and alarm control play a crucial role. On the one hand, material level monitoring can keep track of the inventory of various materials in real time, providing key information for production allocation and thus improving production efficiency. On the other hand, automated material level measurement can significantly reduce the frequency of manual measurement and alleviate the workload of inspection personnel.

[0003] However, most current cement silo level measurement devices can only measure at fixed locations, failing to provide comprehensive and accurate monitoring of material levels at different locations within the silo. For example, in large cement silos, material distribution is often uneven, with significant differences in material levels at different locations. Traditional measurement devices cannot cover all areas of the entire silo, resulting in the inability to detect abnormal material conditions in a timely manner, such as material accumulation, excessively high or low levels.

[0004] To address this issue, we designed a cement silo level measurement device. Utility Model Content

[0005] The purpose of this invention is to provide a cement silo material level measuring device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a cement silo level measuring device, including a laser rangefinder and a cement silo. The laser rangefinder is installed at the top of the cement silo, and a guardrail is fixedly connected to the top wall of the cement silo. A movable component is installed at the bottom of the laser rangefinder. The movable component includes a first support rod and a second support rod, both of which are fixedly connected to the inner wall of the guardrail. A sliding groove is opened on the opposite side of the first and second support rods, and a sliding rod slides between the two sliding grooves. The laser rangefinder is installed on the sliding rod, and a traction line is installed on the sliding rod. Both ends of the traction line are rotated by winding rollers, and both winding rollers are fixedly connected to the inner walls of both sides of the guardrail.

[0007] Furthermore, the laser rangefinder is provided with a protective shell, and a laser head is fixedly connected to the bottom of the laser rangefinder. The inner bottom wall of the protective shell has a placement groove, and the laser head is inserted into the placement groove. Support legs are fixedly connected to both sides of the bottom of the protective shell, and a base plate is fixedly connected to the bottom of the support legs. Threaded holes are provided on the base plate, and bolts are threaded into the threaded holes.

[0008] Furthermore, the slide bar has an insertion hole, and the bottom end of the bolt is threaded into the insertion hole.

[0009] Furthermore, a protective cover is installed on the outer surface of the placement slot, and the protective cover is made of transparent acrylic.

[0010] Furthermore, a detection hole is provided in the middle of the slide bar, and the bottom end of the laser head is opposite to the detection hole.

[0011] Furthermore, the traction line is fixedly connected to the top of the protective shell.

[0012] Furthermore, heat dissipation holes are provided through both sides of the protective shell, and cooling fans are installed in the heat dissipation holes.

[0013] Furthermore, a crank handle is rotatably connected to the winding roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This cement silo level measurement equipment features a movable component design that allows the laser rangefinder to move flexibly on the top of the cement silo. Through the cooperation of the sliding grooves and sliding rods on the first and second support rods, as well as the action of the traction line and winding roller, the operator can easily adjust the laser rangefinder to different positions inside the silo for measurement. This flexibility can adapt to different measurement needs. For example, when the material distribution inside the silo is uneven or when it is necessary to focus on monitoring certain specific areas, the level information can be obtained more comprehensively and accurately.

[0016] This cement silo material level measurement equipment utilizes a laser rangefinder for precise distance measurement, combined with the synergistic effect of a series of supporting components such as a protective shell, heat dissipation, installation and fixing, and auxiliary calibration, to achieve real-time, accurate, and stable measurement of material level under harsh working conditions such as high dust, fluctuating temperature, and frequent vibration in cement silos, providing a reliable basis for material control in the cement production process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 2 and Figure 3 This utility model provides a technical solution: a cement silo level measuring device, including a laser rangefinder 1 and a cement silo 12. The laser rangefinder 1 is installed at the top of the cement silo 12. A guardrail 13 is fixedly connected to the top wall of the cement silo 12. A moving component is installed at the bottom of the laser rangefinder 1. The moving component includes a first support rod 14 and a second support rod 15. The first support rod 14 and the second support rod 15 are both fixedly connected to the inner wall of the guardrail 13. A sliding groove 16 is opened on the opposite side of the first support rod 14 and the second support rod 15. A sliding rod 17 slides between the two sliding grooves 16. The laser rangefinder 1 is installed on the sliding rod 17. A traction line 19 is installed on the sliding rod 17. A winding roller 20 rotates at both ends of the traction line 19. The two winding rollers 20 are fixedly connected to the inner walls of both sides of the guardrail 13.

[0025] In practice, the sliding rod 17 is pulled by the traction line 19, thereby moving the sliding rod 17 within the slide groove 16. In this way, the laser rangefinder 1 can move to different positions on the sliding rod 17 to measure the material level at different positions of the cement silo 12.

[0026] See Figure 4 and Figure 5 The laser rangefinder 1 is equipped with a protective shell 2. A laser head 3 is fixedly connected to the bottom of the laser rangefinder 1. A placement groove 4 is opened on the inner bottom wall of the protective shell 2. The laser head 3 is inserted into the placement groove 4. Support legs 6 are fixedly connected to both sides of the bottom of the protective shell 2. A base plate 7 is fixedly connected to the bottom of the support legs 6. A threaded hole 8 is opened on the base plate 7. A bolt 9 is threadedly connected to the threaded hole 8. An insertion hole is opened on the slide rod 17. The bottom end of the bolt 9 is threadedly connected to the insertion hole.

[0027] In practice, the combination design of the outriggers 6, the base plate 7, the threaded holes 8, and the bolts 9 facilitates the installation and fixation of the equipment in the insertion holes on the top of the cement silo. Operators can adjust the position of the bolts 9 in the threaded holes 8 according to the installation site layout on the top of the silo to achieve precise positioning and stable installation of the equipment.

[0028] See Figure 5 A protective cover 5 is installed on the outer surface of the placement slot 4. The protective cover 5 is made of transparent acrylic.

[0029] In practice, the transparent acrylic protective cover 5 has good light transmission properties, which makes it easy for the laser beam to pass through the protective cover 5 at the bottom of the protective shell 2.

[0030] See Figure 2 A detection hole 18 is provided in the middle of the slide bar 17, and the bottom end of the laser head 3 is opposite to the detection hole 18.

[0031] In practice, the bottom of the laser head 3 is opposite to the detection hole 18 to ensure that when the laser beam is emitted vertically downward, it can measure the material level inside the cement silo 12 through the detection hole 18.

[0032] See Figure 1 The traction line 19 is fixedly connected to the top of the protective shell 2.

[0033] In practice, when the traction line 19 rotates through the winding rollers 20 set at both ends, it drives the protective shell 2 to move, thereby adjusting the position of the laser rangefinder 1.

[0034] See Figure 5 The protective shell 2 has heat dissipation holes 10 through its two side walls, and a cooling fan 11 is installed inside the heat dissipation holes 10.

[0035] In practice, due to the harsh environment of the cement silo, with a lot of dust and large temperature fluctuations, the laser rangefinder 1 will generate heat when it works continuously. When the cooling fan 11 is working, it effectively reduces the temperature inside the protective shell 2, preventing the laser rangefinder 1 from experiencing performance degradation or even failure due to overheating, ensuring its long-term stable operation and continuous output of accurate measurement data.

[0036] See Figure 3 A crank handle is rotatably connected to the winding roller 20.

[0037] In practice, the winding roller 20 is rotated by turning the crank handle, thereby changing the length of the traction line 19.

[0038] Working principle: The semiconductor laser is located inside the laser rangefinder 1. When the device is started, the laser emits a laser beam. This laser beam passes through the protective cover 5 at the bottom of the protective shell 2 and shines directly onto the surface of the material inside the cement silo 12. The material surface reflects the laser beam, and the reflected light returns along the original path and is received by the receiver of the laser rangefinder 1. By accurately recording the time difference between laser emission and reception, and based on the speed of light in the air, the distance between the laser rangefinder 1 and the material surface can be calculated, thereby determining the material level height inside the cement silo 12. In addition, the protective shell 2 provides physical protection for the entire device. The placement slot 4 inside provides a stable installation position for the laser head 3, ensuring that the laser beam is emitted vertically downwards. On the other hand, in conjunction with the protective cover 5, it prevents a large amount of cement dust from entering the interior of the protective shell 2 without affecting laser propagation, thus avoiding damage to the laser rangefinder 1, ensuring the cleanliness of its optical components, and maintaining measurement accuracy.

[0039] When it is necessary to adjust the position of the laser rangefinder 1 at the top of the cement silo 12, the slide bar 17 is pulled by the traction line 19. The two ends of the traction line 19 are respectively wound around the winding roller 20. The winding roller 20 can be rotated by a crank to change the length of the traction line 19, thereby driving the slide bar 17 to move within the slide groove 16. In this way, the laser rangefinder 1 can be moved to different positions on the slide bar 17 to realize the measurement of the material level at different positions in the cement silo 12.
