Description

Technical Field

[0001] This utility model relates to the field of coal powder collector technology, and in particular to a coal powder aggregate sample collection device. Background Technology

[0002] Generally, coal powder is used as fuel in places like thermal power plants and cement plants. Coal powder is collected for quality control and to ensure combustion efficiency. However, because coal powder has varying particle sizes, samples taken from the same downcomer are less representative. Therefore, if coal powder needs to be collected at different times, insufficient sampling continuity can affect the effectiveness of subsequent coal powder testing. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where coal powder collection is insufficient due to insufficient collection continuity when collection occurs at different times. Therefore, this invention proposes a coal powder aggregate sample collection device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A coal powder aggregate sample collection device is designed, comprising a connecting pipe, with several sleeves arranged on the outside of the connecting pipe, all of which are connected to the connecting pipe. Each of the sleeves has a cap at one end, a movable rod at each cap, and a piston at one end of each movable rod. The pistons are slidably disposed within the sleeves. A rotating rod is connected to one end of the connecting pipe via a bearing. The vertical projections of the pistons are all located on the rotating rod. A connecting groove is formed at one end of the rotating rod, and in one working state, the connecting groove is connected to one of the sleeves. An alert component is provided on the connecting pipe.

[0006] Preferably, there are gaps between the plurality of sleeve tubes, and the plurality of sleeve tubes are staggered.

[0007] Preferably, both the outer side of the rotating rod and the inner wall of the connecting pipe are provided with a wear-resistant coating.

[0008] Preferably, the reminder component includes a through groove formed on the connecting pipe, a first connecting sleeve is provided in the through groove, a first sliding rod is provided in the first connecting sleeve, a first elastic element is provided at one end of the first sliding rod, one end of the first elastic element abuts against the inside of the first connecting sleeve, and an adjustment mechanism is provided between the first sliding rod and the rotating rod.

[0009] Preferably, the adjusting mechanism includes a second connecting sleeve installed on the outer side of one end of the rotating rod, a second sliding rod is provided inside the second connecting sleeve, a second elastic element is provided at one end of the second sliding rod, and one end of the second elastic element abuts against one side of the rotating rod. In one of the working states, one end of the first sliding rod is in contact with one end of the second sliding rod.

[0010] Preferably, one end of both the first sliding rod and the second sliding rod is configured as an arc shape.

[0011] Preferably, both the first elastic element and the second elastic element are cylindrical springs, and the elastic potential energy of the second elastic element is much greater than that of the first elastic element.

[0012] Preferably, the outer sides of the connecting pipe and the plurality of sleeve pipes are provided with anti-slip textures.

[0013] The present invention provides a coal powder aggregate sample collection device, which has the following advantages: After the coal powder aggregate sample collection device is connected to the collection end on the coal powder conveying pipeline through the connecting pipe, the rotating rod is rotated by using a torque wrench. During the rotation of the rotating rod, the position of the connecting groove is adjusted, so that the connecting groove is connected to several sleeve tubes in sequence, allowing the coal powder to enter the inside of several sleeve tubes respectively. Multiple sample collection operations can be performed at one time, thereby reducing the difficulty of coal powder collection. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figure 1-5 A coal powder aggregate sample collection device includes a connecting pipe 1, with several sleeves 2 arranged on the outside of the connecting pipe 1, all of which are connected to the connecting pipe 1. Each sleeve 2 has a cap 3 at one end, and a moving rod 4 is located at each cap 3. A piston 5 is located at one end of each moving rod 4, and the pistons 5 are slidably disposed within the sleeves 2. A rotating rod 6 is connected to one end of the connecting pipe 1 via a bearing. The vertical projections of the pistons 5 are all located on the rotating rod 6. A connecting groove 7 is formed at one end of the rotating rod 6, and in one working state, the connecting groove 7 is connected to one of the sleeves 2. A reminder component is provided on the connecting pipe 1, the reminder component including components formed on the connecting pipe... A through groove 8 is provided on the 1, and a first connecting sleeve 9 is provided in the through groove 8. A first sliding rod 10 is provided in the first connecting sleeve 9. A first elastic element 11 is provided at one end of the first sliding rod 10. One end of the first elastic element 11 abuts against the first connecting sleeve 9. An adjustment mechanism is provided between the first sliding rod 10 and the rotating rod 6. The adjustment mechanism includes a second connecting sleeve 12 installed on the outside of one end of the rotating rod 6. A second sliding rod 13 is provided in the second connecting sleeve 12. A second elastic element 14 is provided at one end of the second sliding rod 13. One end of the second elastic element 14 abuts against one side of the rotating rod 6. In one working state, one end of the first sliding rod 10 is in contact with one end of the second sliding rod 13.

[0022] After connecting the connecting pipe 1 to the collection end on the pulverized coal conveying pipeline, the rotating rod 6 is rotated by using a torque wrench. During the rotation, the position of the connecting groove 7 is adjusted, so that the connecting groove 7 will be connected to several sleeves 2 in sequence, allowing pulverized coal to enter the interior of several sleeves 2 respectively. This causes the pistons 5 inside several sleeves 2 to move, and one end of the moving rod 4 inside several sleeves 5 extends out of the cap 3. This allows the device to perform multiple sample collection operations at one time, thereby reducing the difficulty of pulverized coal collection.

[0023] Furthermore, during the rotation of the rotating rod 6, it will rotate together with the second connecting sleeve 12, causing the first sliding rod 10 and the second sliding rod 13 to be misaligned. This allows the first sliding rod 10 to enter the first sleeve tube 10 after one end of the first sliding rod 10 is squeezed by the elastic potential energy of the first elastic element 11. This makes it easier for the operator to determine whether the connecting groove 7 and the several sleeve tubes 2 are in a connected state by the position of the first sliding rod 10 after the collection is completed. This also makes it less likely for the coal powder in the several sleeve tubes 2 to be mixed up after the device collects the data.

[0024] Example 2: An optimization based on Example 1, with reference to... Figure 1-5 One end of the first sliding rod 10 and the second sliding rod 13 are both set in an arc shape. The first elastic element 11 and the second elastic element 14 are both set as cylindrical springs. The elastic potential energy of the second elastic element 14 is much greater than that of the first elastic element 11. The outer sides of the connecting pipe 1 and the several sleeves 2 are all provided with anti-slip textures. There are gaps between the several sleeves 2 and the several sleeves 2 are staggered. The outer side of the rotating rod 6 and the inner wall of the connecting pipe 1 are both provided with wear-resistant coatings.

[0025] The rotating rod 6 is made of molded rubber material. By setting the outer side of the rotating rod 6 and the inner wall of the connecting pipe 1 to have a wear-resistant coating, the service life of the rotating rod 6 can be increased.

[0026] By setting the elastic potential energy of the second elastic element 14 to be much greater than that of the first elastic element 11, after the first sliding rod 10 and the second sliding rod 13 are aligned, one end of the second sliding rod 13 will inevitably extend into the through groove 8, so that one end of the first sliding rod 10 is attached to the connecting pipe 1, thereby making it easier to confirm the position of the connecting groove 7 on the rotating rod 6.

[0027] Combined with appendix Figure 1-4 It can be seen that by having gaps between several sleeves 2 and staggering the arrangement of several sleeves 2, the several sleeves 2 are located on both sides of the connecting pipe 2, and there are gaps between several sleeves 2, so that after the coal powder in one sleeve 2 is taken out first, the coal powder in the other sleeve 2 is in a state where it cannot be taken out, thereby reducing the cross-contamination of coal powder in several sleeves 2 and improving the grouping effect of coal powder.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
