Description

Technical Field

[0001] This invention belongs to the technical field of belt conveyors, and particularly relates to an anti-clogging belt conveyor. Background Technology

[0002] A belt conveyor is a device that carries and transports materials via a conveyor belt running on a conveyor frame. Typically, it consists of two rotating pulleys supported at both ends of the frame. The conveyor belt is fitted onto the two pulleys and driven by a conveyor motor, allowing materials to be transported from one end of the belt conveyor to the other. Existing sludge drying systems generally employ multiple conveyor belts arranged in a staggered pattern. Sludge is sequentially transported from one conveyor belt to the next, achieving a top-down drying process for environmentally friendly processing. Mesh openings are typically created in the conveyor belts for ventilation and drying. However, due to the moisture content of the sludge, it sometimes adheres to the conveyor belt, accumulating and preventing proper discharge. While scrapers are used for cleaning, they often clog the mesh, hindering airflow and reducing drying efficiency. Therefore, the existing structure needs to be upgraded to avoid clogging the mesh while still achieving sludge separation. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention solves the following problem: When sludge is transported on a conveyor belt, due to the sludge's certain moisture content, it sometimes adheres to the conveyor belt and accumulates thickly, preventing the sludge from being discharged normally. For this reason, it is usually cleaned by scrapers. However, scrapers often clog the mesh during cleaning, resulting in poor air permeability and reduced drying effect.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: An anti-clogging belt conveyor includes a processing box, an upper conveyor belt, a bottom conveyor belt, and a material pressing and suction assembly. Multiple upper conveyor belts are installed inside the processing box, arranged in a staggered pattern from top to bottom and left to right. The bottom conveyor belt is installed at the lower end of the processing box. Mesh openings are evenly distributed on both the upper and bottom conveyor belts. A material pressing and suction assembly is installed on the lower side of each upper conveyor belt. Each material pressing and suction assembly includes an external pressing pipe, an internal suction pipe, and a control motor. An external pressure tube is installed on the lower side of the belt; the external pressure tube has a structure with one end closed and the other end open; multiple ventilation holes are evenly opened around the external pressure tube; an internal suction tube is inserted into the external pressure tube and inserted through the opening of the external pressure tube; the internal suction tube draws airflow from the upper side of the external pressure tube; a control motor is installed on the processing box, and the control motor drives the external pressure tube to rotate, and the rotation speed of the external pressure tube is matched with the transmission speed of the upper conveyor belt.

[0005] Furthermore, the outer end of the built-in suction tube extends through to the outside of the processing box; a power suction pump is respectively provided on the outer end of the built-in suction tube.

[0006] Furthermore, a longitudinally arranged collection pipe is provided on one side of the interior of the processing box; the longitudinally arranged collection pipe is connected to the outer ends of multiple built-in suction pipes; a recovery pipe is provided at the upper end of the longitudinally arranged collection pipe; the outer end of the recovery pipe extends above the uppermost conveyor belt; and a recovery pump is provided on the recovery pipe.

[0007] Furthermore, multiple control motors are installed on the upper and lower sides of one side of the processing box, and each control motor drives the external pressure tube to rotate.

[0008] Furthermore, one control motor is provided, and the control motor controls the rotation of multiple external pressure tubes through a transmission mechanism; the transmission mechanism includes a drive box, a gear disk, and an extension shaft; the drive box is installed on the inner side of the processing box; an extension shaft is connected to the outer side of the closed end of each external pressure tube, and multiple extension shafts extend into the drive box, with the outer ends of the extension shafts connected to gear disks respectively, and multiple gear disks meshing from top to bottom, the gear disks being rotatably connected in the drive box; the control motor drives one of the gear disks.

[0009] Furthermore, the built-in suction tube has a strip-shaped opening in the upper region inside the external pressure tube.

[0010] Furthermore, a feeding pipe is provided on one side of the upper end of the processing box; a discharge pipe is provided on one side of the lower end of the processing box; the discharge pipe is located below the end of the bottom conveyor belt.

[0011] Furthermore, the upper end of the discharge pipe is provided with a guide plate; the upper end of the guide plate is connected to the lower side of the end of the bottom conveyor belt.

[0012] The beneficial effects of this invention are as follows: 1. In this invention, a pressing and suction assembly is installed on the underside of each upper conveyor belt. The pressing and suction assembly includes an external pressing pipe, an internal suction pipe, and a control motor. The control motor drives the external pressing pipe to rotate, and the rotation speed of the external pressing pipe matches the transmission speed of the upper conveyor belt. This allows the external pressing pipe to rotate relative to the underside of the upper conveyor belt. The contact of the external pressing pipe can crush the attached sludge. At the same time, an internal suction pipe is placed inside the external pressing pipe. The internal suction pipe draws airflow from the upper side of the external pressing pipe, thus absorbing the crushed sludge. The sludge in the mesh is drawn into the internal suction pipe through the vent of the external pressing pipe. This not only separates the attached sludge but also avoids clogging.

[0013] 2. The present invention has a longitudinal collection pipe on one side inside the processing box, which is connected to the outer ends of multiple built-in suction pipes. The upper end of the longitudinal collection pipe is provided with a recovery pipe, and the outer end of the recovery pipe extends to the top of the uppermost conveyor belt. A recovery pump is provided on the recovery pipe. In this way, the sludge attached to the lower side of multiple upper conveyor belts can be recovered to the topmost upper conveyor belt to achieve thorough drying.

[0014] 3. In this invention, a control motor controls the rotation of multiple external pressing tubes via a transmission mechanism. The transmission mechanism includes a drive box, a gear disk, and an extension shaft. The drive box is installed on the inner side of the processing box. An extension shaft is connected to the outer side of the closed end of each external pressing tube. The multiple extension shafts extend into the drive box, and the outer ends of the extension shafts are connected to the gear disks. The multiple gear disks are meshed from top to bottom and are rotatably connected to the drive box. The control motor drives one of the gear disks, and the meshing of the multiple gear disks drives the extension shaft to rotate. The extension shaft drives the external pressing tubes connected to it to rotate, so that the external pressing tubes and their respective upper conveyor belts rotate relative to each other to crush the sludge. The relative rotation greatly reduces friction and improves the stability of the components. Attached Figure Description

Detailed Implementation

[0021] The invention will now be described in further detail with reference to the accompanying drawings. Example 1

[0022] like Figures 1 to 3As shown, an anti-clogging belt conveyor includes a processing box 1, an upper conveyor belt 2, a bottom conveyor belt 3, and a pressing and suction assembly 4. Multiple upper conveyor belts 2 are installed inside the processing box 1, and these upper conveyor belts 2 are staggered from top to bottom and left to right. The bottom conveyor belt 3 is installed at the lower end of the processing box 1. Mesh holes are evenly distributed on the upper conveyor belts 2 and the bottom conveyor belt 3. A pressing and suction assembly 4 is installed on the lower side of each upper conveyor belt 2. The pressing and suction assembly 4 includes an external pressing pipe 41, an internal suction pipe 42, and a control motor 43. An external pressing pipe 41 is installed against the lower side of each upper conveyor belt 2. The external pressing pipe 41 has a structure with one end closed and the other end open. Multiple ventilation holes 411 are evenly distributed around the external pressing pipe 41. Each part is fitted with a built-in suction pipe 42, which is inserted into the opening of the external pressure pipe 41. The built-in suction pipe 42 draws airflow from the upper side of the external pressure pipe 41. The built-in suction pipe 42 has a strip-shaped opening 421 in the upper region inside the external pressure pipe 41, so that suction can be performed through the strip-shaped opening 421. In this embodiment, the outer end of the built-in suction pipe 42 extends through to the outside of the processing box 1. A power suction pump 422 is provided on the outer end of the built-in suction pipe 42 to discharge the attached sludge, which can be stored in an external storage bin. A control motor 43 is installed on the processing box 1, which drives the external pressure pipe 41 to rotate. The rotation speed of the external pressure pipe 41 is matched with the transmission speed of the upper conveyor belt 2 to achieve relative rotation. In this embodiment, multiple control motors 43 are installed on the upper and lower sides of one side of the processing box 1, and each control motor 43 drives the external pressure pipe 41 to rotate. A feed pipe 11 is provided on one side of the upper end of the processing box 1; a discharge pipe 12 is provided on one side of the lower end of the processing box 1; the discharge pipe 12 is located below the end of the bottom conveyor belt 3; a guide plate 13 is provided at the upper end of the discharge pipe 12, and the upper end of the guide plate 13 is connected to the lower side of the end of the bottom conveyor belt 3, which facilitates material discharge. An exhaust hood 14 and an air inlet hood 15 are respectively designed at the upper and lower ends of the processing box 1. Example 2

[0023] like Figure 4 and 5 As shown, this embodiment refers to Embodiment 1, but differs in the suction method of the multiple built-in suction pipes 42. This embodiment achieves a unified sludge collection and a unified recycling and feeding structure. In this embodiment, a longitudinal collection pipe 5 is provided on one side of the inside of the processing box 1; the longitudinal collection pipe 5 is connected to the outer ends of the multiple built-in suction pipes 42; a recycling pipe 6 is provided at the upper end of the longitudinal collection pipe 5; the outer end of the recycling pipe 6 extends to the top of the uppermost conveyor belt 2; a recycling pump 7 is provided on the recycling pipe 6. In this way, the sludge attached to the lower side of the multiple upper conveyor belts 2 can be recycled to the topmost upper conveyor belt 2, achieving thorough drying. Example 3

[0024] like Figures 1 to 5 As shown, this embodiment refers to Embodiment 1 or Embodiment 2, the difference being that this embodiment can drive the rotation of multiple external pressure tubes 41 using a single control motor 43. In this embodiment, only one control motor 43 is provided, and the single control motor 43 controls the rotation of multiple external pressure tubes 41 through a transmission mechanism 8. The transmission mechanism 8 includes a drive box 81, a gear disk 82, and an extension shaft 83. The drive box 81 is installed on the inner side of the processing box 1. An extension shaft 83 is connected to the outer side of the closed end of each external pressure tube 41, and multiple extension shafts 83 extend into the drive box 81. The outer ends of the extension shafts 83 are connected to the gear disks 82, and the multiple gear disks 82 are meshed from top to bottom. The gear disks 82 are rotatably connected within the drive box 81. The control motor 43 drives one of the gear disks 82. In this embodiment, the meshing of multiple gear discs 82 drives the extension shaft 83 to rotate, and the extension shaft 83 drives the external pressing pipes 41 connected to it to rotate. This causes the external pressing pipes 41 to rotate relative to their respective upper conveyor belts 2, crushing the sludge. The direction of rotation is shown in the attached figure. Figure 3 By using relative rotation, friction is greatly reduced, thus improving the stability of the components.

[0025] In this invention, a pressing and suction assembly 4 is installed on the underside of each upper conveyor belt 2. The pressing and suction assembly 4 includes an external pressing pipe 41, an internal suction pipe 42, and a control motor 43. The control motor 43 drives the external pressing pipe 41 to rotate, and the rotation speed of the external pressing pipe 41 matches the transmission speed of the upper conveyor belt 2. This allows the external pressing pipe 41 to rotate relative to the underside of the upper conveyor belt 2. The contact of the external pressing pipe 41 can crush the attached sludge. At the same time, an internal suction pipe 42 is placed inside the external pressing pipe 41. The internal suction pipe 42 draws airflow from the upper side of the external pressing pipe 41, thus absorbing the crushed sludge. The sludge in the mesh is drawn into the internal suction pipe 42 through the vent 411 of the external pressing pipe 41. This not only separates the attached sludge but also avoids clogging.

[0026] The present invention has a longitudinal collection pipe 5 on one side inside the processing box 1. The longitudinal collection pipe 5 is connected to the outer end of multiple built-in suction pipes 42. The upper end of the longitudinal collection pipe 5 is provided with a recovery pipe 6. The outer end of the recovery pipe 6 extends to the top of the uppermost conveyor belt 2. The recovery pipe 6 is provided with a recovery pump 7. In this way, the sludge attached to the lower side of multiple upper conveyor belts 2 can be recovered to the topmost upper conveyor belt 2 to achieve thorough drying.

[0027] In this invention, a control motor 43 controls the rotation of multiple external pressing tubes 41 via a transmission mechanism. The transmission mechanism includes a drive box 81, a gear disk 82, and an extension shaft 83. The drive box 81 is installed on the inner side of the processing housing 1. An extension shaft 83 is connected to the outer side of the closed end of each external pressing tube 41. Multiple extension shafts 83 extend into the drive box 81, and the outer ends of the extension shafts 83 are connected to the gear disks 82. The multiple gear disks 82 are meshed from top to bottom and are rotatably connected to the drive box 81. The control motor 43 drives one of the gear disks 82, and the meshing of the multiple gear disks 82 drives the extension shaft 83 to rotate. The extension shaft 83 drives the external pressing tubes 41 connected to it to rotate, so that the external pressing tubes 41 rotate relative to each other with the upper conveyor belt 2 to crush the sludge. The relative rotation greatly reduces friction and improves the stability of the components.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
