Description

Technical Field

[0001] The invention relates to the technical field of cement sampling, in particular to an automatic clinker sampling device and a sampling method thereof. Background Art

[0002] Cement clinker is a semi-finished product obtained by mixing limestone, clay and iron raw materials in appropriate proportions, burning them until they are partially or completely melted, and cooling them. In the cement industry, the most commonly used silicate cement clinker has calcium oxide, silicon dioxide and a small amount of aluminum oxide and iron oxide as its main chemical components. The main mineral components are tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite. With the development of the cement industry, safety production and product quality have become a priority, and product testing is of great importance. The test results can be used as a basis for timely adjustment of system conditions. Quality inspectors of cement clinker production lines take instantaneous samples (1-2 hours) during equipment operation.

[0003] Patent announcement number CN114414296A discloses an automatic sampling device for cement clinker and a clinker zipper machine. The automatic sampling device for cement clinker includes: a base assembly; a large arm assembly, one end of which is hinged to the base assembly and swings horizontally; a small arm assembly, one end of which is hinged to the large arm assembly and swings vertically; and a sampling unit, which is hinged to the other end of the small arm assembly. The automatic sampling device for cement clinker and the clinker zipper machine of the present invention realize the function of the sampling unit being retractable in the horizontal and vertical directions by means of the large arm assembly and the small arm assembly installed on the base assembly, and the sampling unit can realize automatic sampling; after the sampling is completed, the sampling device can be reset to the outside of the zipper machine to avoid the sampling device being retained above or inside the clinker for a long time, which greatly improves the operability in installation and maintenance, and increases the service life of the sampling device.

[0004] Although the device has many beneficial effects, the following problems still exist: the device manual states that "the upper arm assembly and the lower arm assembly on the base assembly realize the function of retracting the sampling unit in the horizontal and vertical directions" and it uses a large number of power structures for auxiliary work, which leads to high use costs and subsequent maintenance costs, which is not conducive to enterprise use. Summary of the invention

[0005] The object of the present invention is to provide a clinker automatic sampling device and a sampling method thereof to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic clinker sampling device, comprising an outer shell, a collecting hopper, a support column, a hopper, a discharge port, a first limit column, a second limit column and a baffle, a support plate is installed on one side of the inner wall of the outer shell, a chain is arranged on the outer wall of the support plate, equidistant and parallel hoppers are installed on the outer walls on both sides of the chain, a discharge port is opened at the lower end of the inner wall of the hopper, a collecting hopper is installed on both sides of the inner wall of the outer shell, a support frame is installed on both sides of the inner wall of the collecting hopper, the first limit column and the second limit column are respectively installed on the outer walls of the upper ends of the two support frames, a support column is installed on one side of the outer wall of the lower end of the hopper, a bearing is installed on the outer wall of the support column, and a baffle is rotatably installed on the outer wall of the bearing.

[0007] When using an automatic clinker sampling device and a sampling method thereof in the technical solution, an external motor drives the sprocket and the chain transmission, thereby causing the hopper to rotate inside the outer shell. During the continuous movement of the hopper, the first limit post contacts the left outer wall of the baffle, and because the position of the first limit post is stable, the baffle is pushed to rotate in a circle through the bearing and the discharge port is exposed. The material inside the hopper falls into the collecting hopper through the discharge port, thereby completing the purpose of sampling the material. During the continuous movement of the hopper, the second limit post contacts the right outer wall of the baffle, and because the position of the second limit post is stable, the baffle is pushed to reset through the bearing, thereby ensuring the blocking effect of the baffle on the discharge port, and the material inside the collecting hopper can be discharged through the discharge pipe.

[0008] Preferably, the hopper is distributed in an upside-down shape inside the shell, and the hopper is located at the upper and lower ends of the collecting hopper;

[0009] The chain is driven by an external sprocket, and the sprocket is connected to an external motor. The motor can drive the chain to rotate, thereby causing the hopper to rotate inside the shell.

[0010] Preferably, a discharge pipe is installed in the outer wall of the lower end of the collecting bucket, and one end of the discharge pipe passes through the outer shell. The material inside the collecting bucket can be discharged through the discharge pipe, which is convenient for the staff to collect the material.

[0011] Preferably, the first limiting column is installed at the front of the upper end of the support frame, and the second limiting column is installed at the rear of the upper end of the support frame;

[0012] After the hopper moves to the upper end of the support frame, the first limiting column contacts the left outer wall of the baffle during the continuous movement of the hopper. Since the position of the first limiting column is stable, the baffle is pushed to rotate in a circle through the bearing and expose the discharge port. The material in the hopper falls into the collecting hopper through the discharge port, thereby completing the purpose of sampling the material.

[0013] During the continuous movement of the hopper, the second limiting column contacts the right outer wall of the baffle, and since the position of the second limiting column is stable, the baffle is pushed to reset through the bearing, thereby ensuring the blocking effect of the baffle on the discharge port.

[0014] Preferably, the size of the baffle is larger than the inner wall of the discharge port, the outer walls on both sides of the baffle are designed in an inclined shape, and the position of the baffle corresponds to the discharge port. The baffle can cover the discharge port to ensure that the material inside the hopper is controlled and discharged through the discharge port;

[0015] A sealing gasket is fixed to the outer wall of the upper end of the baffle, and the sealing gasket is in contact with the outer wall of the lower end of the hopper. The sealing gasket can ensure the sealing between the baffle and the hopper to prevent the material inside the hopper from flowing out through the gap. The elastic force of the sealing gasket itself squeezes the baffle and the hopper respectively, which can ensure the relative stability of the baffle at the lower end of the hopper.

[0016] A sampling method of a clinker automatic sampling device comprises the following steps:

[0017] Step 1: The external motor drives the sprocket and chain transmission, so that the hopper rotates inside the shell;

[0018] Step 2: During the continuous movement of the hopper, the first limiting column contacts the left outer wall of the baffle, and because the position of the first limiting column is stable, the baffle is pushed to rotate in a circle through the bearing, and the discharge port is exposed. The material inside the hopper falls into the collecting hopper through the discharge port, thereby completing the purpose of sampling the material;

[0019] Step 3: During the continuous movement of the hopper, the second limiting column contacts the outer wall of the right side of the baffle plate, and because the position of the second limiting column is stable, the baffle plate is pushed to reset through the bearing, thereby ensuring the baffle plate's blocking effect on the discharge port;

[0020] Step 4: The materials inside the collection bucket can be discharged through the discharge pipe, making it convenient for the staff to collect the materials.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention achieves the effect of facilitating the sampling of materials by setting a collecting bucket, a first limiting column, a second limiting column and a baffle, and can control the working position of the baffle so that the material inside the hopper enters the collecting bucket, avoiding the addition of a power structure to assist in material collection, reducing the cost of use and subsequent maintenance costs, ensuring the sample demand, and having strong representativeness, thereby reducing the safety risks of staff in sampling.

[0032] See also Figures 1 to 6 , the present invention provides three embodiments:

[0033] Embodiment 1: A clinker automatic sampling device and a sampling method thereof, comprising a housing 1, a collecting hopper 2, a support column 3, a hopper 13, a discharge port 14, a first limiting column 23, a second limiting column 24 and a baffle 32, a support plate 11 is installed on one side of the inner wall of the housing 1, and a chain 12 is arranged on the outer wall of the support plate 11. Due to the position stability of the support plate, the chain 12 is ensured to rotate outside the support plate 11, and the circumferential rotation stability of the material strip 12 and the hopper 13 can be ensured. The outer walls of both sides of the chain 12 are installed with equidistantly distributed hoppers 13, and the material is inside the hopper 13 and the housing 1. The materials are stored between the hopper 13 so that the hopper 13 can drive the materials to move during the rotation. A discharge port 14 is provided at the lower end of the inner wall of the hopper 13. Collecting hoppers 2 are installed on both sides of the inner wall of the outer shell 1. Support frames 22 are installed on both sides of the inner wall of the collecting hopper 2. The first limiting column 23 and the second limiting column 24 are respectively installed on the outer walls of the upper ends of the two support frames 22. A support column 3 is installed on one side of the outer wall of the lower end of the hopper 13. A bearing 31 is installed on the outer wall of the support column 3. A baffle 32 is rotatably installed on the outer wall of the bearing 31. The baffle 32 ensures the stability and smoothness of the circular rotation through the support column 3 and the bearing 31.

[0034] The hopper 13 is distributed in an upside-down shape inside the housing 1, and the hopper 13 is located at the upper and lower ends of the collecting hopper 2;

[0035] The chain 12 is driven by an external sprocket, and the sprocket is connected to an external motor. The motor can drive the chain 12 to rotate, thereby causing the hopper 13 to rotate inside the housing 1.

[0036] Embodiment 2: A clinker automatic sampling device and a sampling method thereof, comprising a shell 1, a collecting hopper 2, a support column 3, a hopper 13, a discharge port 14, a first limit column 23, a second limit column 24 and a baffle 32, a support plate 11 is installed on one side of the inner wall of the shell 1, a chain 12 is arranged on the outer wall of the support plate 11, equidistant and parallel hoppers 13 are installed on the outer walls on both sides of the chain 12, a discharge port 14 is provided at the lower end of the inner wall of the hopper 13, a collecting hopper 2 is installed on both sides of the shell 1, a support frame 22 is installed on both sides of the inner wall of the collecting hopper 2, a first limit column 23 and a second limit column 24 are respectively installed on the outer walls of the upper ends of the two support frames 22, a support column 3 is installed on one side of the outer wall of the lower end of the hopper 13, a bearing 31 is installed on the outer wall of the support column 3, and a baffle 32 is rotatably installed on the outer wall of the bearing 31.

The outer walls on both sides of the baffle 32 are designed in an inclined shape, and the position of the baffle 32 corresponds to the discharge port 14. The baffle 32 can cover the discharge port 14 to ensure that the material inside the hopper 13 is discharged through the discharge port 14 in a controlled manner. During the continuous movement of the hopper 13, the first limiting column 23 contacts the left outer wall of the baffle 32, and because the position of the first limiting column 23 is stable, the baffle 32 is pushed to rotate in a circle through the bearing 31 and expose the discharge port 14. The material inside the hopper 13 passes through the discharge port 14 falls into the collecting hopper 2, thereby completing the purpose of sampling the material. During the continuous movement of the hopper 13, the second limiting column 24 contacts the right outer wall of the baffle 32, and because the position of the second limiting column 24 is stable, the baffle 32 is pushed to reset through the bearing 31, ensuring the blocking effect of the baffle 32 on the discharge port 14. According to the rotation speed of the hopper, the sampling frequency is maintained at 5 to 6 minutes to take a part. When the equipment runs for 1 hour, the sample demand can be met, and the instantaneous sample is changed into a random sample, and the representativeness of the quality inspection data is improved;

[0038] A sealing gasket 33 is fixed to the outer wall of the upper end of the baffle 32, and the sealing gasket 33 is in contact with the outer wall of the lower end of the hopper 13. The sealing gasket 33 can ensure the sealing between the baffle 32 and the hopper 13 to prevent the material inside the hopper 13 from flowing out through the gap. The elastic force of the sealing gasket 33 itself squeezes the baffle 32 and the hopper 13 respectively, which can ensure the relative stability of the baffle 32 at the lower end of the hopper 13.

[0039] Embodiment three: A clinker automatic sampling device and a sampling method thereof, comprising a shell 1, a collecting hopper 2, a support column 3, a hopper 13, a discharge port 14, a first limit column 23, a second limit column 24 and a baffle 32, a support plate 11 is installed on one side of the inner wall of the shell 1, a chain 12 is arranged on the outer wall of the support plate 11, equidistant and parallel hoppers 13 are installed on the outer walls on both sides of the chain 12, a discharge port 14 is provided at the lower end of the inner wall of the hopper 13, a collecting hopper 2 is installed on both sides of the shell 1, a support frame 22 is installed on both sides of the inner wall of the collecting hopper 2, a first limit column 23 and a second limit column 24 are respectively installed on the outer walls of the upper ends of the two support frames 22, a support column 3 is installed on one side of the outer wall of the lower end of the hopper 13, a bearing 31 is installed on the outer wall of the support column 3, and a baffle 32 is rotatably installed on the outer wall of the bearing 31.

[0040] A discharge pipe 21 is installed on the outer wall of the lower end of the collecting bucket 2. One end of the discharge pipe 21 passes through the outer shell 1. The material inside the collecting bucket 2 can be discharged through the discharge pipe 21, which is convenient for the staff to collect the material. The discharge pipe 21 is designed in an inclined shape. The material inside the collecting bucket 2 can slide through the discharge pipe 21 until it is discharged through the discharge pipe 21.

[0041] The first limiting column 23 is installed at the front of the upper end of the support frame 22, and the second limiting column 24 is installed at the rear of the upper end of the support frame 22;

[0042] After the hopper 13 moves to the upper end of the support frame 22, the first limiting column 23 contacts the left outer wall of the baffle 32 during the continuous movement of the hopper 13. Since the position of the first limiting column 23 is stable, the baffle 32 is pushed to rotate in a circle through the bearing 31, and the discharge port 14 is exposed. The material inside the hopper 13 falls into the collecting hopper 2 through the discharge port 14, thereby completing the purpose of sampling the material.

[0043] During the continuous movement of the hopper 13, the second limiting column 24 contacts the right outer wall of the baffle 32, and since the position of the second limiting column 24 is stable, the baffle 32 is pushed to reset through the bearing 31, thereby ensuring the blocking effect of the baffle 32 on the discharge port 14, reducing the labor intensity of the workers, keeping the employees away from the running equipment, and reducing the safety risks of the employees.

[0044] The size of the baffle 32 is larger than the inner wall of the discharge port 14. The outer walls on both sides of the baffle 32 are designed in an inclined shape. The position of the baffle 32 corresponds to the discharge port 14. The baffle 32 can cover the discharge port 14 to ensure that the material inside the hopper 13 is controlled and discharged through the discharge port 14.

[0045] A sealing gasket 33 is fixed to the outer wall of the upper end of the baffle 32, and the sealing gasket 33 is in contact with the outer wall of the lower end of the hopper 13. The sealing gasket 33 can ensure the sealing between the baffle 32 and the hopper 13 to prevent the material inside the hopper 13 from flowing out through the gap. The elastic force of the sealing gasket 33 itself squeezes the baffle 32 and the hopper 13 respectively, which can ensure the relative stability of the baffle 32 at the lower end of the hopper 13.

[0046] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
