Description

Technical Field

[0001] This invention relates to a material channel cleaning device, and more particularly to a cleaning device for a confined space area of ​​a material channel. Background Technology

[0002] In various industries such as metallurgy and building materials, material handling channels are commonly used to transport various solid materials, especially those containing a certain amount of moisture. However, blockages can easily occur in the enclosed spaces of these channels due to impaired flow. When a blockage occurs, an incision needs to be made at the corresponding location to clear the obstruction. During this process, material may spill out of the incision, significantly increasing the workload for on-site workers. Furthermore, frequent blockages at the same location can severely impact material transport efficiency. Summary of the Invention

[0003] Purpose of the invention: This invention addresses the problem of frequent material blockage in enclosed spaces of material channels by providing a material clearing device for enclosed spaces of material channels.

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

The lower end of the device cylinder is connected to the material channel shell flange through a connecting flange, and the device cylinder can rotate relative to the material channel shell flange.

[0007] Two device limiting core blocks are set on the inner side of the device cylinder. A screw shaft limiting groove and two sliding block limiting grooves are formed between the two device limiting core blocks. The two sliding block limiting grooves are distributed on both sides of the screw shaft limiting groove. The screw shaft limiting groove and the rod and slider in the middle of the screw shaft form a sliding pair. One of the sliding block limiting grooves forms a sliding pair with the sliding connector and the left cleaning rod, and the other sliding block limiting groove forms a sliding pair with the sliding connector and the right cleaning rod.

[0008] The screw thread at the upper part of the screw shaft passes through the cover plate hole and forms a threaded connection with the handwheel nut block. The lower end of the screw shaft is connected to the left and right cleaning rods respectively through two connecting rod assemblies. The upper end of the sliding connector is provided with a connecting shoulder, which cooperates with the limiting block to axially limit the sliding connector. The lower end of the sliding connector forms a rotating connection pair with the left and right cleaning rods respectively.

[0009] Furthermore, a cylinder flange ring and a cylinder retaining ring are spaced apart at the lower end of the device cylinder. The inner part of the connecting flange is inserted between the cylinder flange ring and the cylinder retaining ring. The cylinder flange ring and the inner part of the connecting flange are connected by a first bolt assembly, and the outer part of the connecting flange is connected to the material channel shell flange by a second bolt assembly.

[0010] Furthermore, a handwheel is provided on the outside of the device cylinder for rotating the device cylinder.

[0011] Furthermore, the device has through holes on both sides of the cylinder for installing limiting blocks.

[0012] Furthermore, a nut limiting ring is fixed on the end cover plate of the device, and the nut limiting ring cooperates with the handwheel nut block to axially limit the handwheel nut block.

Detailed Implementation

[0029] The invention will now be further explained with reference to the accompanying drawings.

[0030] like Figure 1 As shown, a material cleaning device for a confined space in a material channel according to the present invention includes a cleaning device housing assembly 1, a screw shaft 2, a handwheel nut block 4, a sliding coupling 5, a connecting rod assembly 7, a left cleaning rod 8, a right cleaning rod 9, a connecting flange 12, and a material channel housing flange 14. The material channel housing flange 14 is provided with an opening on the side of the material channel housing for fixing the cleaning device.

[0031] like Figure 5As shown, the cleaning device housing assembly 1 includes a device cylinder 15, a device end cover plate 16, a limiting block 18, and a device limiting core block 19. The device end cover plate 16 is provided at the upper end of the device cylinder 15, and the device end cover plate 16 has a cover plate hole 16a in the middle. The limiting block 18 is provided on the side of the device cylinder 15. The lower end of the device cylinder 15 is connected to the material channel housing flange 14 through a connecting flange 12, and the device cylinder 15 can rotate relative to the material channel housing flange 14.

[0032] In this embodiment, a cylinder flange ring 15a and a cylinder retaining ring 15b are spaced apart at the lower end of the device cylinder 15. The inner part of the connecting flange 12 is inserted between the cylinder flange ring 15a and the cylinder retaining ring 15b. The cylinder flange ring 15a is connected to the inner part of the connecting flange 12 by a first bolt assembly 11, and the outer part of the connecting flange 12 is connected to the material channel housing flange 14 by a second bolt assembly 13. The cleaning device housing assembly 1, the connecting flange 12, and the material channel housing flange 14 are fixed together by the first bolt assembly 11 and the second bolt assembly 13. After the first bolt assembly 11 is removed, the device cylinder 15 can rotate freely.

[0033] In this embodiment, a device handwheel 17 is provided on the outside of the device cylinder 15 for rotating the device cylinder 15.

[0034] In this embodiment, two through holes are symmetrically provided on both sides of the device cylinder 15 for installing the limiting block 18. The limiting block 18 is inserted into the through hole from the outside of the device cylinder 15.

[0035] like Figure 1 and 6 As shown, two device limiting core blocks 19 are provided inside the device cylinder 15. A screw shaft limiting groove 19a and two sliding block limiting grooves 19b are formed between the two device limiting core blocks 19. The two sliding block limiting grooves 19b are distributed on both sides of the screw shaft limiting groove 19a. The screw shaft limiting groove 19a and the rod slider 2b in the middle of the screw shaft 2 form a sliding pair. One of the sliding block limiting grooves 19b forms a sliding pair with the sliding connecting member 5 and the left cleaning rod member 8, and the other sliding block limiting groove 19b forms a sliding pair with the sliding connecting member 5 and the right cleaning rod member 9.

[0036] like Figure 1 and 4 As shown, the upper screw thread 2a of the screw shaft 2 passes through the cover plate hole 16a and forms a threaded connection with the handwheel nut block 4. The lower end of the screw shaft 2 is connected to the left cleaning rod 8 and the right cleaning rod 9 respectively through two connecting rod assemblies 7. The upper end of the sliding connecting member 5 is provided with a connecting member shoulder 5a, which cooperates with the limiting block 18 to axially limit the sliding connecting member 5. The lower end of the sliding connecting member 5 forms a rotating connection pair with the left cleaning rod 8 and the right cleaning rod 9 respectively through the second pin assembly 10.

[0037] In this embodiment, a nut limiting ring 3 is fixed on the end cover plate 16 of the device. The nut limiting ring 3 cooperates with the handwheel nut block 4 to axially limit the handwheel nut block 4.

[0038] like Figure 2 and 3 as well as Figures 7 to 13 As shown, the screw shaft 2 is connected to one end of the two connecting rod assemblies 7 via the connecting pin hole 2c at its lower end and the first pin assembly 6. The left cleaning rod 8 and the right cleaning rod 9 are connected to the other end of the two connecting rod assemblies 7 via the left rod pin hole 8a and the right rod pin hole 9a, respectively.

[0039] When the manual nut block 4 is rotated, the screw shaft 2 can only move up and down due to the axial limiting effect of the nut limiting ring 3 and the limiting effect of the sliding pair formed between the rod slider 2b and the screw shaft limiting groove 19a. When the screw shaft 2 moves downward, the screw shaft 2 drives the left cleaning rod 8 and the right cleaning rod 9 to rotate outward simultaneously through the connecting rod assembly 7 because the limiting block 18 limits the axial end of the sliding connecting member 5 through the shoulder end 5a of the connecting member. When the screw shaft 2 moves upward, the screw shaft 2 drives the left cleaning rod 8 and the right cleaning rod 9 to move upward together through the connecting rod assembly 7. When the upper end face of the rod slider 2b contacts the lower surface of the device end cover plate 16, the screw shaft 2 will be restricted from moving upward.

[0040] When the screw shaft 2 moves downward, and after the left and right cleaning rods 8 and 9 rotate outward to the appropriate position, the first bolt assembly 11 fixing the cylinder flange ring 15a can be removed. By rotating the handwheel 17, the blockage in the material channel can be cleared under the rotation of the left and right cleaning rods 8 and 9. When the handwheel 17 is rotated, the entire cleaning device is axially limited by the action of the cylinder flange ring 15a and the cylinder retaining ring 15b.

[0041] After the blockage in the material channel is cleared, the screw shaft 2 is moved to the highest position to prevent the left cleaning rod 8 and the left cleaning rod 9 from causing new blockage in the material channel.

[0042] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
