Automatic material addition is achieved without closing the ash conveying channel, and idle filter disks can be cleaned.

Description

Technical Field

[0001] This utility model relates to the field of pipeline filtration technology. Specifically, it relates to a pipeline filter. Background Technology

[0002] In coal-fired power generation technology, a large amount of dust is generated during fuel combustion. Existing pneumatic ash conveying technology can be used to carry dust and smoke through the pipe using gas, so that the dust and smoke are carried to the designated equipment. When cleaning the existing ash conveying pipeline filter, it is often necessary to disassemble and clean the filter. Not only does it require stopping the ash conveying pipeline, but it also requires disassembly and cleaning of the filter. In addition, the addition of dehumidifying materials requires manual labor, making the operation steps cumbersome. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to provide a pipeline filter that divides the pipe body into two parts by an upper partition and a lower partition, so that one filter disc can filter, while the other filter disc automatically drops the dehumidifying items inside vertically during rotation, and can automatically add items to the middle part after unloading.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] The device includes a tube body, a rotating disk rotatably mounted in the middle of the tube body, filter disks rotatably mounted on both sides of the rotating disk, a reset strip integrally mounted on one side of each filter disk, an isolation mechanism inside the tube body, the isolation mechanism including an upper partition and a lower partition, an extrusion port on one side of the upper partition, a lifting block on the edge of the rotating disk, a rotating door rotatably mounted on one side of the tube body, and a discharge mechanism on one side of the rotating door, the discharge mechanism including a discharge pipe, a discharge valve and a first spring, the discharge pipe integrally mounted on one side of the rotating door, and the discharge valve slidably mounted on the surface of the discharge pipe.

[0006] The technical solution of this utility model has achieved the following beneficial technical effects:

[0007] This solution divides the pipe body into two parts using upper and lower partitions, allowing one filter disc to perform filtration while the other filter disc automatically drops dehumidifying materials vertically during rotation. After unloading, materials can be automatically added to the middle section, and the filter disc can be leveled again during rotation, enabling it to rotate to one side of the pipe body for alternating operation. Automatic material addition is possible without closing the ash conveying channel, and idle filter discs can be cleaned for the next operation. Attached Figure Description

[0013] This implementation is as per the attached instruction manual. Figure 1 As shown, the instruction manual is attached. Figure 1 The tube 1 was cut in half. It can be seen that, isolated by the upper baffle 5 and lower baffle 6, the gas flows downwards along the tube 1, passing through the filter disc 3 on the right side (the filter disc 3 is shown as a semicircle in the diagram, but can actually be an arc less than 180 degrees to ensure sufficient space for rotation; the surface of the filter disc is a filter screen, which is not shown due to its dense structure). This design clearly defines the installation direction as vertical, and the gas flow as downwards. The rotating disc 2 rotates between the upper baffle 5 and lower baffle 6. The upper baffle 5 and lower baffle 6 are fixed inside the tube 1, and the upper baffle 5, lower baffle 6, and rotating disc 2 are sealed (with corresponding sealing rings), therefore there is no air leakage. When the phenomenon occurs, the upper partition 5 and the lower partition 6 clamp the rotating disk 2 between them and rotate it. A corresponding rotation center is set. A toothed groove is set above the rotation center of the rotating disk 2, which can mesh with the driving tooth 23. A drive motor is installed above the driving tooth 23. The drive motor is a servo motor in the prior art, which has a power-off self-locking function. Therefore, the rotating disk 2 can be rotated under the drive of the drive motor. In this solution, the rotating disk 2 rotates 180 degrees each time. Each rotation of the rotating disk 2 has the effect of replacing the filter disk 3, so that one filter disk 3 is working and the other filter disk 3 is idle. A rotating door 9 is set on one side of the tube body 1. The rotating door 9 can be opened, so the idle side of the tube body 1 can be cleaned regularly.

[0014] As per the instruction manual Figure 2 As described above, two sets of structures are provided below the revolving door 9: the first set is the discharge pipe 10, and the second set is the adapter block 18 (in...). Figure 2 The position of the top-mounted block 8 was not specified because the shape of the adapter block 18 was too small. Figure 2 (While labelling), and on the upper side of the upper partition 5 (relative to) Figure 2 (For example) A shaping block is provided, and an extrusion port 7 is provided on the lower side of the upper partition 5. The shaping block is semi-circular in shape, and the extrusion port 7 is a semi-circle with a portion removed. This ensures that there is enough space for the reset strip 4 to rotate. (Refer to the instruction manual attached.) Figure 1 As shown, at this time, the extrusion port 7 is above the reset bar 4, so it can only prevent the reset bar 4 from rotating to one side, but cannot prevent it from rotating to the other side. Therefore, this solution will cause the filter disc 3 to rotate by an angle when it rotates to the side of the rotating door 9. A corresponding counterweight 15 is set on the edge of the filter disc 3, and the rotation center of the rotating disc 2 is in the middle, so the counterweight 15 can press downwards, making the filter disc 3 vertical. (See the attached instruction manual.) Figure 1 The image shows a horizontal orientation, not a vertical one. A ring-shaped storage opening 14 is located in the center of the filter disc 3, allowing filtered materials to be discharged and fall onto the left side of the tube body 1 (see attached instruction manual). Figure 1 (From the perspective of the user), complete the discarding of filtered items;

[0015] The previous paragraph explained that when filter disc 3 is in a certain position, it will be vertical, allowing the dehumidifying materials on filter disc 3 to be removed. Rotating disc 2 continues to rotate clockwise, as shown in the instruction manual. Figure 2 At this time, the vertical reset bar 4 will contact the extrusion port 7, causing the filter disc 3 to rotate horizontally, and proceed to the next step, which is the discharge pipe 10 of this scheme to discharge the material.

[0016] Before discharging, please refer to the instructions attached. Figure 2 The ( Figure 2 The partition in the middle blocks part of the reset strip 4, but the upper partition 5 has a sloping slope and does not actually block the rotation of the reset strip 4. The lower lifting block 8 is in contact with the adapter block 18.

[0017] As per the instruction manual Figure 4 As shown, a support rod 16 is integrally installed on the inner wall of the revolving door 9, and a striking rod 17 is slidably installed on the lower surface of the support rod 16. The revolving door 9 in this design can be opened and closed. Closing the revolving door 9 only requires installing a corresponding lock on it. The support rod 16 is L-shaped, but the intersection angle of the L-shape is less than 90 degrees, not 90 degrees. Figure 4The angle is difficult to see clearly. The upper part of the support rod 16 is vertical to one side of the revolving door 9, so the lower part of the support rod 16 moves diagonally to the right towards the adapter block 18. The striking rod 17, which limits the sliding motion below the support rod 16, also slides diagonally downwards. Figure 4 The remaining sliding parts are vertical or horizontal. The cross-section of the support rod 16 is elliptical. The groove above the striking rod 17 is adapted to slide the support rod 16, thus preventing the striking rod 17 from rotating. The adapter block 18 is vertically slidably mounted on the revolving door 9, and has a second spring 19 below it. The second spring 19 is in a stretched state, which causes the adapter block 18 to move downward. Since there is no space below the adapter block 18, a lifting block 8 is provided on the edge of the rotating disk 2 in this design. The lifting block 8 has high and low points, and its shape corresponds to that of the adapter block 18. Therefore, when the rotating disk 2 rotates, the adapter block 18 can move up and down on the lifting block 8. This design uses this up and down movement to strike the rotating disk 2. The actual difference between the high and low points of the lifting block 8 is large, and the adapter block 18... As the device moves downwards, a slope on one side compresses the reset block 21. A reset spring 22 is located on one side of the reset block 21. The spring force of the reset spring 22 is very small, so it resets again after compression. At this point, the reset block 21 is above the adapter block 18. As the adapter block 18 moves upwards, it carries the reset block 21 upwards with it. The upward movement of the reset block 21 causes the striking rod 17 to move upwards as well. As mentioned above, the sliding trajectory of the striking rod 17 is diagonally downwards, so its upward movement is diagonally upwards. When it reaches the top, the edge of the reset block 21 disengages from the adapter block 18. Because the upward movement compresses the striking spring 20, the striking spring 20 stores its force and moves rapidly downwards, completing the impact on the rotating disk 2. The rotating disk 2 then impacts, as shown in the attached instruction manual. Figure 2 As shown, the filter disc 3 can be made vertical, so the dust filtered on the filter disc 3 can be shaken, and the dehumidifying items on the annular storage port 14 can be shaken down.

[0018] Dehumidifiers will be refilled after they fall, as per the instruction manual. Figure 3 As shown ( Figure 3(The lifting block 8 is not shown coming over; this is just a description in this paragraph.) As the lifting block 8 rotates to the position of the discharge pipe 10, the reset strip 4 on one side of the filter disc 3 has been pressed horizontally by the extrusion port 7. Since the shape of the lifting block 8 was described in the previous paragraph, this shape will also cause the discharge valve 11 to move up and down (one side of the discharge valve 11 has the exact same shape as one side of the adapter block 18, and one side of the discharge valve 11 also has a first spring 12 similar to the second spring 19, both of which are stretched to cause the discharge valve 11 to move downwards). Therefore, similarly, as the lifting block 8 contacts one side of the discharge valve 11, the discharge valve 11 can... The discharge valve 11 can move up and down. When it moves downward, it can move the particles inside the discharge channel 13 along the edge of the rotating disk 2 (the edge of the rotating disk 2 is set to be open) to the annular storage port 14 (which can be designed to be lower in sequence, such as the edge opening of the rotating disk 2 being lower, the annular storage port 14 being the lowest, and the discharge channel 13 being the highest), thus adding dehumidified materials (the discharge pipe 10 in this solution is filled with granular quicklime). When the discharge valve 11 moves upward, the lower part of the discharge channel 13 will be blocked by the discharge pipe 10, and when the discharge valve 11 moves downward, the upper part of the discharge channel 13 will be blocked by the discharge pipe 10, thus forming a one-way conveying.
