Description

Technical Field

[0001] This utility model relates to the field of sampler technology, specifically to a slag discharge sampler for thermal power plants. Background Technology

[0002] Thermal power plants typically generate heat by burning coal and then convert that heat into electricity. The degree of coal combustion directly affects the production cost of a thermal power plant with the same capacity. Therefore, in order to ensure the full combustion of coal and control production costs, thermal power plants usually sample the waste residue to determine the degree of coal combustion and whether the waste residue meets emission standards.

[0003] In related technologies, waste residue is often sampled using a slag discharge sampler. The slag discharge sampler includes a housing, with a collection box slidably connected inside the housing. A feed inlet is provided on the housing corresponding to the collection box, located at the top or side of the housing. An adjustable sealing plate is installed above the collection box to open and close the sampling channel between the feed inlet and the collection box, ensuring effective protection after slag discharge sampling and avoiding sample contamination.

[0004] However, during the use of this slag sampler, there may be a height difference between the feed inlet and the waste slag sampling point. The waste slag is prone to causing dust and noise during the falling process, which pollutes the environment and affects the health of the operators. At the same time, during the sampling process, there is a problem that the sampling discharge speed inside the box cannot be controlled, and the sample exceeds the volume of the collection box and overflows and accumulates, which makes it difficult to remove the collection box. Moreover, when the collection box is removed, it is easy to cause slag to spill and pollute the environment. Utility Model Content

[0038] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the slag sampler for thermal power plants in this embodiment of the present invention includes a first housing 1, a second housing 2, a buffer plate 3, a collection box 4, and a sampling box 5. The height direction of the first housing 1 is defined as the up-down direction, the length direction of the first housing 1 is defined as the left-right direction, and the width direction of the first housing 1 is defined as the front-back direction.

[0040] The first box 1 has a support bracket (not shown in the figure) at its bottom, which supports the first box 1. The first box 1 has a first cavity 11 and a discharge port 12 at its bottom. The second box 2 has a second cavity 21 and a feed port 22 at its top. The second box 2 is slidably inserted into the first cavity 11 in the vertical direction and its position is adjustable in the vertical direction. The bottom of the second box 2 has a first opening to connect the first cavity 11 and the second cavity 21. A buffer plate 3 is horizontally rotatably disposed in the second cavity 21. The buffer plate 3 is used to tilt at a set angle when the waste residue passes through the second cavity 21. The collection box 4 is connected to the bottom of the first box 1 corresponding to the discharge port 12. The sampling box 5 is slidably disposed in the collection box 4 in the front-back direction to collect the waste residue.

[0041] In use, the slag sampler for thermal power plants according to this utility model is moved to the slag sampling position. By adjusting the insertion length of the second box 2 inside the first box 1, the height of the second box 2 is adjusted so that the height of the second box 2 and the feed inlet 22 is adapted to the slag sampling point, reducing the contact between the slag and air before it enters the guide box and the second box 2. After the slag enters the second chamber 21 through the guide box and the feed inlet 22, the slag accumulates on the buffer plate 3 and is driven to rotate under the gravity of the slag to tilt. At this time, the slag on the buffer plate 3 slides down the buffer plate 3 and enters the first chamber 11, and then reaches the sampling box 5 in the collection box 4 through the discharge port 12.

[0042] The slag sampler for thermal power plants in this embodiment of the utility model adjusts the height of the feed inlet 22 in real time by moving the second box 2 in the vertical direction, thereby reducing dust flying during the sampling process. At the same time, the buffer plate 3 set in the second cavity 21 can buffer the waste slag, reducing the fly ash and noise generated by the impact during the fall of the waste slag. It is green and environmentally friendly, creating a good working environment for operators.

[0043] Optionally, a guide box is provided on the second housing 2 corresponding to the feed inlet 22. The guide box includes a first conical section connected to the second housing 2 and a first cylindrical section connected to the first conical section. The cross-section of the first conical section increases in the direction away from the second housing 2. A guide port is provided at the top of the first cylindrical section, and the size of the guide port is smaller than the cross-sectional size of the first cylindrical section. When sampling the waste residue, the waste residue first enters the first cylindrical section through the guide port, and then enters the second chamber 21 through the first conical section and the feed inlet 22. The first conical section and the first cylindrical section can guide the waste residue and reduce the amount of dust generated after the waste residue enters the guide box and flies out from the guide port.

[0044] Optionally, a sealing gasket is provided on the inner wall of the first box 1 or the outer wall of the second box 2 to prevent fly ash from flying out from the gap between the first box 1 and the second box 2.

[0045] Optionally, the left and right sides of the buffer plate 3 are rotatably connected to the inner wall of the second housing 2 via bearings. A lever extending radially is provided on the circumference of the bearing, and a block extending radially along the bearing is provided on the buffer plate 3. During the rotation of the buffer plate 3, when it rotates to a set tilt angle, the lever and the block stop and cooperate to limit the maximum rotation angle of the buffer plate 3.

[0046] In some embodiments, such as Figure 2As shown, it also includes a lifting assembly 6, which includes a first shaft 61, a first gear 62, a rack 63, and a driving member 64. The first shaft 61 is rotatably mounted on the first housing 1. The second housing 2 has a third cavity 23. The rack 63 is fixedly mounted in the third cavity 23 and extends in the vertical direction. The second housing 2 has a guide groove extending in the vertical direction corresponding to the third cavity 23. Part of the first shaft 61 passes through the guide groove to extend into the third cavity 23. The first gear 62 is fixedly mounted on the first shaft 61 and meshes with the rack 63. The driving member 64 is used to drive the first shaft 61 to rotate.

[0047] The first shaft 61 is driven to rotate by the drive component 64, and the first shaft 61 drives the first gear 62 to rotate. The first gear 62 drives the rack 63 to rotate in the vertical direction by meshing with the rack 63, thereby realizing the adjustment of the height of the second housing 2. The operation is convenient. The third cavity 23 is provided to hide the first gear 62 and the rack 63, avoiding fly ash leakage that may be caused by the first gear 62 and the rack 63 being placed between the first housing 1 and the second housing 2 or inside the second housing 2. The sealing is reliable.

[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, the lifting assembly 6 includes a second shaft 65, a second gear 66 and a third gear 67. The second shaft 65 is rotatably mounted on the first housing 1, the second gear 66 is fixedly mounted on the second shaft 65, and the third gear 67 is fixedly mounted on the first shaft 61 and meshes with the second gear 66. The driving member 64 is used to drive the second shaft 65 to rotate.

[0049] A second shaft 65 is set up, and a third gear 67 is used as a transmission gear to drive the first gear 62 to rotate. By adjusting the transmission ratio of the second gear 66 and the third gear 67, that is, the number of teeth of the second gear 66 and the third gear 67, the driving force required to rotate the first shaft 61 can be reduced, thereby reducing the amount of manual labor or the operating power of the motor.

[0050] In some embodiments, such as Figure 2 As shown, the first housing 1 is provided with a fourth cavity 13, in which the second gear 66 and the third gear 67 are rotatably disposed. The fourth cavity 13 is provided to hide the second gear 66 and the third gear 67, so as to avoid interference from external objects on the meshing of the second gear 66 and the third gear 67 and ensure the reliability of transmission.

[0051] In some embodiments, the driving component 64 is a first motor. The first motor is fixedly mounted on the first housing 1 and connected to the second shaft 65 through a coupling. By using the first motor as the driving component 64, the workload of personnel is reduced and the adjustment efficiency is high. At the same time, the first motor is a servo motor, which can ensure the fixation of the first shaft 61 in the standby state, and prevent the adjusted second housing 2 from falling relative to the first housing 1 again, which is safe and reliable.

[0052] Optionally, a power supply is provided on the first housing 1, and the first motor is electrically connected to the power supply.

[0053] In some embodiments, such as Figure 1 and Figure 2 As shown, the drive component 64 is an adjustment handle, which is fixedly mounted on the second shaft 65. A fixing bolt 7 is threadedly connected to the first housing 1, and the fixing bolt 7 is used to abut against the outer side of the second housing 2.

[0054] When adjusting the height of the second housing 2, the operator holds the adjustment handle, loosens the fixing bolt 7, and then rotates the adjustment handle, thereby driving the second gear 66 to rotate and move the second housing 2. When the second housing 2 moves to the set position, the fixing bolt 7 is tightened. The fixing bolt 7 presses against the outer wall of the second housing 2 and fixes the position of the second housing 2. Through operator operation, the use of electricity is reduced.

[0055] Optionally, the outer side of the second housing 2 is provided with a plurality of blind holes spaced apart in the vertical direction. When fixing the second housing 2, the fixing bolts 7 are screwed on so that part of them extends into the corresponding blind holes, so that the second housing 2 is stopped and engaged with the fixing bolts 7 in the vertical direction, making the position fixing of the second housing 2 safer and more reliable.

[0056] In some embodiments, such as Figure 3 As shown, it also includes a lifting assembly 6, which includes a drive plate 68, a first screw 69, and a second motor 610. The drive plate 68 is disposed on the second housing 2, the first screw 69 is rotatably disposed on the first housing 1 and extends in the vertical direction, the first screw 69 is threadedly engaged with the drive plate 68, and the second motor 610 is fixedly disposed on the first housing 1 and used to drive the first screw 69 to rotate.

[0057] Specifically, the second motor 610 is fixedly installed on one side of the first housing 1 and connected to a mobile power supply. The output shaft of the second motor 610 is connected to the first screw 69 through a coupling. The first screw 69 is rotatably installed in the first housing 1. Since the second housing 2 is inserted into the first housing 1 in the vertical direction, the rotation of the first screw 69 can move the drive plate 68 in the vertical direction, thereby realizing the adjustment of the height of the second housing 2, which is convenient to operate.

[0058] Optionally, the lifting assembly 6 is provided with two pairs on the left and right sides of the second housing 2, so that the first screw 69 can adjust the height of the second housing 2 more smoothly through the drive plate 68, avoiding jamming between the second housing 2 and the first housing 1, and ensuring high reliability.

[0059] In some embodiments, such as Figure 1 and Figure 4As shown, it also includes an adjustment component 8, which includes a first plate 81 and a second plate 82. The first plate 81 and the second plate 82 are slidably assembled between the collection box 4 and the second box 2 in the left and right directions to block the discharge port 12 or adjust the size of the discharge cross section below the discharge port 12.

[0060] By adjusting the positions of the first plate 81 and the second plate 82, the size of the discharge section below the discharge port 12 can be adjusted to control the discharge speed of waste entering the sampling box 5, avoid the accumulation of waste at the sampling box 5, achieve quantitative acquisition of waste, and at the same time prevent waste residue from leaking from the collection box 4 during sampling, which is green and environmentally friendly.

[0061] In some embodiments, such as Figure 4 As shown, the adjusting assembly 8 includes a connecting plate 83 and a second screw 84. The connecting plate 83 is fixedly connected to the first housing 1. The second screw 84 is rotatably mounted on the connecting plate 83. The second screw 84 includes two threaded sections with opposite directions of rotation and the same length. The first plate 81 and the second plate 82 are respectively threaded onto the two threaded sections of the second screw 84. The second screw 84 is used to drive the first plate 81 and the second plate 82 to move simultaneously toward each other or away from each other.

[0062] Specifically, a third plate 85 is provided on the first plate 81, and a fourth plate 86 is provided on the second plate 82. Part of the third plate 85 and part of the fourth plate 86 extend out of the collection box 4. The connecting plate 83 is L-shaped and fixedly connected to the bottom of the second box 2 and located in front of the collection box 4. The second screw 84 is rotatably set on the rear side of the connecting plate 83. The third plate 85 and the fourth plate 86 are respectively threadedly assembled to the two threaded sections of the second screw 84. A third motor is provided at one end of the second screw 84. The third motor is connected to a mobile power supply. The second screw 84 is driven to rotate by the third motor, thereby realizing the adjustment of the position of the first plate 81 and the second plate 82, which is convenient to operate.

[0063] In some embodiments, such as Figure 1 As shown, multiple buffer plates 3 are spaced apart in the vertical direction. In two adjacent buffer plates 3, the maximum tilt angle of the upper buffer plate 3 is greater than that of the lower buffer plate 3.

[0064] Specifically, there are two buffer plates 3 in the vertical direction. The maximum tilt angle between the upper buffer plate 3 and the horizontal plane is 60°, and the maximum tilt angle between the lower buffer plate 3 and the horizontal plane is 30°. By limiting the maximum tilt angle of the multiple buffer plates 3, the waste material falling from the upper buffer plate 3 onto the lower buffer plate 3 is ensured to have a buffering effect on the waste material.

[0065] Optionally, there are three buffer plates 3 in the vertical direction, and the maximum tilt angle between the middle buffer plate 3 and the horizontal plane is 45°.

[0066] In some embodiments, an elastic element (not shown in the figure) is connected between the buffer plate 3 and the inner wall of the second housing 2. The elastic element is used to drive the buffer plate 3 to rotate to a horizontal state.

[0067] Specifically, the elastic element is a tension spring. Multiple tension springs are provided and are respectively arranged on the front and rear sides of the buffer plate 3. When the weight of the waste on the buffer plate 3 is greater than the tension of the tension spring, the buffer plate 3 rotates to tilt. When the waste on the buffer plate 3 slides down a set amount, the weight of the waste is less than the tension of the tension spring. The tension spring drives the tilting plate to rotate to return to the horizontal position, thereby realizing the quantitative discharge and quantitative sampling of waste.
