Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, and in particular to an ash conveying and anti-clogging device. Background Technology

[0002] Ash conveying anti-blocking devices refer to equipment or combinations of devices that use mechanical, pneumatic, acoustic, or fluidization technologies to prevent or eliminate blockage problems caused by adhesion, caking, and deposition of particulate matter such as fly ash and fly ash during the conveying process, thereby ensuring the continuous and stable operation of the ash conveying system.

[0003] Patent CN215478354U discloses a ash conveying anti-clogging device for purified ash, comprising a device housing. A discharge pipe and a feed pipe are fixedly connected to the left and right ends of the device housing via flanges, respectively. A switch valve is fixedly connected to the left side of the device housing. A filter plate is fixedly connected to the left side of the inner cavity of the device housing. A cylindrical rod is fixedly connected to the lower right side of the inner cavity of the device housing, with a hollow cavity in the middle of the cylindrical rod. A first partition is fixedly connected between the lower right end of the cylindrical rod and the lower right side of the inner cavity of the device housing. A second partition is fixedly connected between the upper end of the cylindrical rod and the upper end of the inner cavity of the device housing. A three-way valve is fixedly connected to the middle of the second partition. By cooperating with the cylindrical rod and the first air outlet pipe, the direction of airflow can be changed, thereby allowing air and material to flow smoothly within the device housing. The spiral motion of the filter plate slows down the clogging of the filter plate. When the filter plate becomes clogged, the drain pipe is opened to discharge the dirt inside the device housing. Then, the second air outlet is opened manually via the three-way valve, while the first air outlet is closed. At the same time, the switch valve is closed. At this time, the air blows from the left side to the right side of the filter plate, which can reach and discharge the blockage, thus facilitating the cleaning of the filter plate. However, the device still clogs during use. Closing the switch valve and opening the second air outlet while closing the first air outlet can effectively clean the blockage, but filter plate clogging still occurs. This increases the workload of the operator to clean the filter plate and cannot clean the blockage in a timely manner. The operator needs to monitor the operation of the device in real time, which increases the workload of the operator.

[0004] Therefore, it is necessary to provide a new ash conveying and anti-clogging device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an ash conveying and anti-clogging device.

[0006] The ash conveying and anti-clogging device provided by this utility model includes: an outer shell, with an inlet and an outlet connected to flanges at both ends of the outer shell, a fixed frame fixedly connected to the inner cavity of the outer shell, a filter cylinder bolted to the top of the fixed frame, the bottom end of the filter cylinder being conical, a drive assembly detachably connected to the bottom end of the filter cylinder, a grinding assembly provided near the top of the filter cylinder, a stirring assembly provided below the grinding assembly, the output end of the drive assembly driving the grinding assembly and the stirring assembly to move synchronously, and multiple through holes opened on the side wall of the bottom end of the filter cylinder.

[0007] Preferably, the grinding assembly includes a grinding plate, which is detachably connected to the inner wall of the filter cylinder. The grinding plate has multiple through holes and multiple protrusions integrally connected to the side of the grinding plate away from the drive assembly. All of the protrusions are conical. The output end of the drive assembly is fixedly connected to a spiral blade that cooperates with the grinding plate for grinding.

[0008] Preferably, the drive assembly includes a mounting frame, which is bolted to the upper end face of the fixing frame. A drive motor is bolted inside the mounting frame. A fixing rod is fixedly connected to the output end of the drive motor. A spiral blade is inserted through the end of the fixing rod away from the drive motor. A stirring assembly is detachably connected to the end of the fixing rod adjacent to the drive motor.

[0009] Preferably, the stirring assembly includes multiple baffles arranged in a circular array around a fixed rod as the central axis. Multiple through slots are formed inside the baffles, and the height of the multiple through slots is less than or equal to the diameter of the through hole.

[0010] Preferably, the baffle is arranged in a right-angled trapezoidal shape, and the inclined sidewall of the baffle is in contact with the bottom sidewall of the filter cylinder.

[0011] Preferably, both the inlet and outlet are equipped with switching valves.

[0012] Compared with related technologies, the ash conveying and anti-clogging device provided by this utility model has the following advantages:

[0013] Beneficial effects:

[0014] 1. By adding grinding and stirring components, the device can automatically grind large particles to the size that can pass through the through hole, avoiding clogging of the filter cartridge. The drive component automates the clogging prevention process, significantly reducing the workload of operators.

[0015] 2. The rotating baffle of the mixing component fits against the inner wall of the filter cylinder, forcibly mixing the material and pushing it through the through holes to prevent particle accumulation. The through grooves on the baffle further refine the material. Combined with the particle size control after grinding, continuous flow is formed, reducing the frequency of downtime for cleaning.

[0016] 3. The bottom of the filter cylinder is conical, and the distribution of through holes facilitates the material's gravity fall and the coordinated conveying of the spiral blades, improving the material conveying efficiency. At the same time, it increases the pressure on the material at the bottom, providing greater power for the material to pass through the through holes and further reducing the possibility of material accumulation.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Figure 4 This is a partial structural cross-sectional schematic diagram of the ash conveying and anti-clogging device provided by this utility model.

[0028] In practical implementation, an ash conveying and anti-clogging device has the following structure: Figure 1 — Figure 4 As shown, it includes: a shell 1, with a feed inlet 2 and a discharge outlet 3 connected to the two ends of the shell 1 by flanges respectively; a fixing frame 4 is welded to the inner cavity of the shell 1; a filter cylinder 5 is bolted to the side of the fixing frame 4 near the feed inlet 2; the filter cylinder 5 is conical at the end near the discharge outlet 3; a drive assembly 6 is bolted to the bottom end of the filter cylinder 5; a grinding assembly 7 is provided near the top end of the filter cylinder 5; a stirring assembly 8 is provided below the grinding assembly 7; the output end of the drive assembly 6 drives the grinding assembly 7 and the stirring assembly 8 to move synchronously; and multiple through holes 9 are opened on the side wall of the bottom end of the filter cylinder 5.

[0029] It should be noted that during the ash conveying process, the outer shell 1 is set vertically, and then ash is conveyed into the outer shell 1 through the inlet 2 set at the top of the outer shell 1. Then, the drive component 6 is started, and the drive component 6 drives the grinding component 7 to grind the larger diameter particles. The ground particles will pass through the through hole 9 under the stirring of the stirring component 8, and then be discharged from the outer shell 1 through the outlet 3.

[0030] The grinding assembly 7 includes a grinding plate 71, which is flanged to the inner wall of the filter cylinder 5. The grinding plate 71 has multiple through holes 72. Multiple protrusions 73 are integrally connected to the side of the grinding plate 71 away from the drive assembly 6. All protrusions 73 are conical. The output end of the drive assembly 6 is welded with a spiral blade 74 that cooperates with the grinding plate 71 for grinding.

[0031] It should be noted that there is a gap between the spiral blade 74 and the grinding plate 71. The distance between the bottom end of the spiral blade 74 and the grinding plate 71 is less than or equal to the diameter of the second through hole 72. The diameter of the second through hole 72 is equal to the diameter of the first through hole 9. Under the action of the spiral blade 74, the larger diameter particles rotate relative to the grinding plate 71. The protrusion 73 on the side of the grinding plate 71 near the feed inlet 2 grinds the larger diameter particles with the spiral blade 74, so that the particles are ground into particles with a diameter less than or equal to the diameter of the second through hole 72. This allows the particles to pass smoothly through the second through hole 72 and the first through hole 9, thereby avoiding blockage caused by the particles. The protrusion 73 improves the grinding efficiency of the particles and improves the working efficiency of the equipment.

[0032] The drive assembly 6 includes a mounting frame 61, which is bolted to the upper end face of the fixing frame 4. A drive motor 62 is bolted inside the mounting frame 61. A fixing rod 63 is welded to the output end of the drive motor 62. A spiral blade 74 is welded to the end of the fixing rod 63 away from the drive motor 62. A stirring assembly 8 is inserted into the end of the fixing rod 63 adjacent to the drive motor 62.

[0033] The stirring assembly 8 includes multiple baffles 81, all of which are welded to the side wall of the fixing rod 63. The multiple baffles 81 are arranged in a circular array with the fixing rod 63 as the central axis. Multiple through slots 82 are opened in the baffles 81, and the height of the multiple through slots 82 is less than or equal to the diameter of the through hole 9.

[0034] It should be noted that the fixed rod 63 is rotated by the drive motor 62, and the fixed rod 63 drives the spiral blade 74 to grind the larger diameter particles until the larger diameter particles can pass through the second through hole 72 smoothly. After the particles pass through the second through hole 72, multiple baffles 81 stir the particles under the drive of the fixed rod 63, which increases the flow rate of the particles. Since the side wall of the baffle 81 is in contact with the side wall of the filter cylinder 5, the particles are prevented from accumulating at the first through hole 9, thus preventing the particles from clogging at the first through hole 9.

[0035] The baffle 81 is arranged in a right-angled trapezoidal shape, and the inclined side wall of the baffle 81 is attached to the bottom side wall of the filter cylinder 5.

[0036] Both the inlet 2 and the outlet 3 are equipped with switch valves 10.

[0037] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
