Description

Technical Field

[0001] The utility model belongs to the field of clinker vertical lift weight detection, and specifically relates to a clinker vertical lift weight detection device. Background Art

[0002] The weight per liter of clinker is one of the reference bases for evaluating the quality of clinker and the firing temperature in the kiln (mainly the firing zone temperature). The weight per liter of clinker = (total weight - weight of liter drum) / volume of liter drum (g / l). The kiln condition can be evaluated by measuring the weight per liter of clinker particles with a particle size of 5mm-7mm.

[0003] Currently, cement plant quality inspection laboratories primarily rely on manual testing for neutral weight testing. This process requires operators to collect samples at on-site clinker sampling points, manually place clinker in the laboratory, manually activate a vibrating screen for screening, and then conduct testing. Clinker sampling, particle size screening, and testing are all performed manually. Post-test processing, such as discarding materials, still requires human intervention. The equipment's test data and results are not linked to the intelligent laboratory, resulting in a low level of automation and intelligence. The testing process is lengthy, labor-intensive, and requires time-bound execution. Different operators can also introduce uncontrollable human errors.

[0004] A utility model patent, CN203991281U, published on December 10, 2014, discloses an online sampling device for measuring the vertical weight of expanded clinker. The device comprises a modified vibrating conveyor, a trough, a sieve plate assembly, and a sampling port. The sieve plate assembly is welded to the trough and includes a first sieve plate with a 7mm pore diameter and a second sieve plate with a 5mm pore diameter. The first and second sieve plates are arranged parallel to each other, dividing the trough from top to bottom into a first cavity, a second cavity, and a third cavity. The sampling port is located on the side of the second cavity, and the sampling port and the trough are connected by an oblique guide plate. The modified vibrating conveyor is equipped with a discharge port for connecting to a chain bucket truck. The first and third cavities are both connected to the discharge port, and a baffle is provided between the second cavity and the discharge port. This online sampling device for measuring the vertical weight of expanded clinker cannot measure the vertical weight of clinker and cannot ensure accurate test data. Utility Model Content

[0024] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0025] like Figures 1 to 4 As shown, the clinker vertical weight detection device includes a frame 1, a screening device is provided in the frame 1, the screening device includes a screening layer 2, a discharge funnel 4 is connected to the side of the screening layer 2, a quantitative material cup 3 is provided below the discharge funnel 4, a quantitative device is provided below the quantitative material cup 3, and a discard port 6 and a weighing sensor 7 are also provided in the frame 1.

[0026] The device can realize the functions of screening, quantification, weighing and discarding of clinker. The material can be obtained into clinker of specified particle size range through multi-layer screening. The quantitative material cup 3 is used to receive the material. The material vibrator 5 and the leveling device serve as the quantitative device of the material to ensure that the amount of material is consistent in each vertical weight detection, thereby ensuring the accuracy of the weighing data. The weighing sensor 7 is used to weigh the quantified material and feed back the weighing data to the host computer. The discard port 6 can discharge the weighed material.

[0027] like Figure 1 and Figure 2As shown, the dosing device includes a material vibrator 5, which is arranged below the dosing cup 3. A flattening support 14 is provided on one side of the dosing cup 3. A flattening cylinder 15 is provided on the flattening support 14. The piston rod of the flattening cylinder 15 is connected to a flattening scraper 16. The bottom of the material vibrator 5 is connected to a lifting mechanism. When the dosing cup 3 is receiving material, the material vibrator 5 is lifted and started to vibrate the material. When the dosing cup 3 is full and the material level reaches a certain height, the material is stopped. The flattening cylinder 15 drives the flattening scraper 16 to extend and scrape the mouth of the dosing cup 3 flat, so that the amount of material in the dosing cup 3 is determined. That is, the dosing cup 3 can proceed to the next step of bearing weight to determine whether its vertical weight meets the standard.

[0028] like Figure 1 As shown, the screening layers 2 are stacked and arranged, and the screening layers 2 are provided with three layers. The working principle of clinker screening: the on-site automatic sampler takes out the clinker with uneven particle size from the middle or head of the oblique zipper and enters the feed port 22 on the first screening layer 2 through the discharge chute; the screening device is divided into three layers, and each screening layer 2 is provided with screens of different specifications. The first layer screens out clinker with a particle size of 7 mm or more. This part of the material does not meet the particle size requirements and can directly enter the downstream crusher or the clinker storage through the discharge funnel 4 of the first layer. The second layer screens out materials with a particle size of 5 mm or more, and the third layer is the residue with a particle size of less than 5 mm. The material screened out in the second layer is the material required to detect the weight per liter. The material screened out in the third layer also does not meet the particle size requirements and directly enters the downstream discard hopper or the clinker storage.

[0029] like Figure 2 and Figure 4 As shown, an X-axis cylinder 8 is provided within the frame 1. The piston rod of the X-axis cylinder 8 is connected to a cylinder fixing plate 9. A Y-axis cylinder 10 is provided on the cylinder fixing plate 9. The piston rod of the Y-axis cylinder 10 is connected to a rotary cylinder 11. The piston rod of the rotary cylinder 11 is connected to a material cup fixing ring 12. The quantitative material cup 3 is provided with a fixing groove 13 adapted to the material cup fixing ring 12. The material cup fixing ring 12 cooperates with the fixing groove 13 to stably clamp the quantitative material cup 3. The stably clamped quantitative material cup 3 is driven by the X-axis and Y-axis cylinders to achieve horizontal and vertical movement. It can be placed on the weighing sensor 7. After the material is weighed, the quantitative material cup 3 is driven by the rotary cylinder 11 to rotate the material cup fixing ring 12, and the material in the quantitative material cup 3 is poured into the discard port 6.

[0030] like Figure 3 As shown, the flattening scraper 16 is provided with a waist-shaped hole 17, and the flattening scraper 16 is bolted to the piston rod of the flattening cylinder 15. By adjusting the relative position of the bolt on the waist-shaped hole 17, the height of the flattening scraper 16 can be adjusted. This not only prevents the metering cup 3 from interfering with the movement of the flattening scraper 16, but also ensures that the material on the metering cup 3 is scraped to the required level.

[0031] like Figure 1 As shown, the discharge hoppers 4 are staggered. A discharge hopper 4 is designed on each screening layer 2. The three discharge hoppers 4 are used to screen materials with different particle size ranges. The staggered arrangement can improve the structural compactness of the screening device. At the same time, the first and third discharge hoppers 4 can be connected to the discard hopper or clinker storage to recycle materials that do not meet the particle size requirements.

[0032] like Figure 2 As shown, a guide rail 19 is further provided in the frame 1, and the cylinder fixing plate 9 is provided on the guide rail 19, and the guide rail 19 is connected to a drag chain 20. The cylinder fixing plate 9 is provided on the guide rail 19 to ensure that the quantitative material cup 3 moves accurately along the Y direction, and the drag chain 20 can play a traction and protection role for its built-in cable.

[0033] like Figure 1 As shown, the material vibrator 5, the discard port 6 and the weighing sensor 7 are arranged in sequence and are all located on one side of the guide rail 19. This design can reduce the moving distance of the quantitative material cup 3 and reduce the repeated actions of the cylinder.

[0034] like Figure 1 As shown, a dust cover 18 is provided outside the discharge funnel 4 on the second screening layer 2. During the material receiving process of the quantitative material cup 3, in order to prevent dust particles in the material from affecting the detection environment, a dust cover 18 is provided outside the discharge funnel 4 to reduce the diffusion of dust particles.

[0035] like Figure 1 As shown, the upper end of frame 1 is equipped with a lifting ring 21. Frame 1 is constructed of welded square tubes. The four lifting rings 21 on the inner end of frame 1 facilitate the transfer of the entire device. Using square tubes reduces manufacturing costs while ensuring sufficient strength. The bottom of frame 1 accommodates electrical control components such as an electrical control box.

[0036] The clinker vertical lift weight detection device is an automated equipment supporting the intelligent quality control system. It realizes the full process automation of clinker vertical lift weight detection by linking with the clinker sending station, crusher, waste hopper and host computer.

[0037] If a sampling device for the middle part of the oblique zipper is installed in the field, the equipment can be used directly in conjunction with it. The sampling is carried out using the middle sampler of the oblique zipper. After the test is completed, the discarded material is discarded back to the oblique zipper using the discard hopper. If a sampling device for the middle part of the oblique zipper is not installed in the field, the equipment can be installed to the head of the oblique zipper (the top of the clinker bin), and the sampling is carried out using the head sampler. After the test is completed, the discarded material is discarded back to the clinker bin by gravity using the discard pipe. The device has high versatility, and the above two installation methods are for users to choose.

[0038] The best usage state is to use it as the clinker vertical weight detection equipment module of the intelligent quality control system of the cement plant. It can be used in conjunction with other equipment such as sample preparation equipment to achieve full automation of the detection process. The detection calculation results can be directly uploaded to the host computer to further improve the report content of the cement plant laboratory system.

[0039] The conventional process for vertical weight detection of clinker is as follows: pour the clinker manually taken from the clinker chain bucket conveyor onto a sieving screen, start the vibrating motor, and sieve the vibrating screen, allowing clinker smaller than 7mm to pass through the sieve holes and leak into the 5mm sieve. When the rate of clinker passing through the 5mm sieve per minute does not exceed 30g, stop the vibrating motor, pour the clinker remaining on the 7mm sieve, and pour the clinker with a vertical diameter of 5-7mm remaining on the 5mm sieve into a weighing cylinder. Use a glass plate to scrape off the clinker that exceeds the mouth of the weighing cylinder so that it is level with the surface of the cylinder, and then weigh it. It should be noted that the sieve holes of the vibrating screen should be cleaned frequently to ensure that the sieve holes are unobstructed.

[0040] After using this device, the vertical weight detection implementation process of clinker is as follows: the material to be tested is introduced into the screening device. After screening, clinker particles with a particle size of 5mm-7mm are screened out from the screening device. In the initial state, each cylinder is in a retracted state. The X-axis cylinder 8 and the Y-axis cylinder 10 are running to drive the quantitative material cup 3 to rise to the receiving position. The discharge funnel 4 is opened, and the quantitative material cup 3 starts to receive the material. At the same time, the material vibrator 5 is lifted to vibrate the material in the quantitative material cup 3. When the material level detection device detects that the material level at the upper end of the quantitative material cup 3 reaches a certain height, the screening device suspends work, the discharge funnel 4 is closed, and the leveling cylinder 15 drives the leveling scraper 16 to extend to scrape the mouth of the quantitative material cup 3 flat, the material vibrator 5 descends, and the X-axis cylinder 8 and the Y-axis cylinder 10 drive the quantitative material cup 3 to descend to the weighing sensor 7. The system reads data from the weighing sensor 7, calculates the result, and uploads it to the host computer system. Then the Y-axis cylinder 10 drives the quantitative material cup 3 to rise to the material receiving position, the X-axis cylinder 8 moves to the discarding position, and the rotary cylinder 11 rotates to pour out the clinker in the quantitative material cup 3. The pipe below the discarding device enters the discarding hopper or clinker storage, and each cylinder returns to its initial position to prepare for the next detection process.

[0041] Compared to existing manual and semi-automatic clinker lift weight detection equipment, this device can achieve unmanned operation of the entire testing process, from sampling, screening, quantification, weighing, and discarding, reducing employee labor intensity. The material quantification by the material vibrator 5 and the leveling device ensures the stability of the material weighing calculation results and avoids human errors caused by manual operation. The device has a reasonable design, is easy to use, has a compact structure, and takes up little space. Compared to existing testing equipment, this device can serve as a supplement to intelligent quality control systems, achieving online linkage to achieve full automation of the clinker lift weight detection process, further improving the automation level of cement plant laboratory testing.
