Description

Technical Field

[0001] This utility model relates to the technical field of pipeline belt conveyors, specifically a pipeline belt conveyor. Background Technology

[0002] During the conveying of bulk materials, conventional belt conveyors are prone to dust spillage. Therefore, in order to prevent dust spillage from bulk materials, pipes are installed on the outside of the conveyor belt to form a closed transport system, which is the pipe belt conveyor.

[0003] Existing pipeline belt conveyors simply integrate conventional conveyor belts inside a pipeline to form a pipeline conveyor. However, particles of bulk materials easily adhere to the surface of the conveyor belt and can easily become embedded in the belt under the pressure of the conveyor belt and belt idlers, which can easily cause belt damage and reduce the service life of the belt.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed a pipeline belt conveyor. Utility Model Content

[0005] The purpose of this invention is to provide a pipeline belt conveyor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe-type belt conveyor, comprising a pipe shell, with rotating rollers rotatably connected to both the front and rear ends of the inner surface of the pipe shell, and a support roller rotatably connected to the middle of the inner surface of the pipe shell. Both the rotating roller and the support roller are configured as concave rollers that are wide at both ends and narrow in the middle. A conveyor belt is sleeved on the surface of the rotating roller. A drive motor is fixedly installed on the right front side of the outer surface of the pipe shell, and the output shaft end of the drive motor passes through the pipe shell and is connected to the front rotating roller. Cleaning mechanisms are provided on both the front and rear sides of the lower inner surface of the pipe shell.

[0007] Preferably, the cleaning mechanism includes a bracket fixedly installed on both the front and rear sides of the bottom of the inner surface of the pipe shell, and two cleaning rollers are rotatably installed on the inner side of the bracket, with the gap in the middle of the cleaning rollers allowing the conveyor belt to pass through.

[0008] Preferably, the cleaning mechanism further includes gears that are fixedly connected to the right end of the sweeping rollers via connecting rods through the bracket, and the gears mesh with each other. A rotary motor is fixedly installed on the left side of the bracket, and the rotary motor is connected to the upper sweeping roller.

[0009] Preferably, air supply pipes are fixedly installed on both the left and right sides of the lower inner wall of the pipe shell, and air inlet branch pipes are evenly distributed and fixedly connected to the upper surface of the air supply pipes, with the upper end of the air inlet branch pipes communicating with the inside of the pipe shell.

[0010] Preferably, the front end of the air supply pipe is fixedly connected to the same dust filter box, and an exhaust fan is fixedly installed on the front side of the outer surface of the dust filter box.

[0011] Preferably, the dust filter box has an openable and closable sealed door on its surface, a filter plate is installed inside, and the exhaust fan is connected to the inside of the dust filter box by a pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the arrangement of a cleaning mechanism, a bracket, a cleaning roller, a gear and a rotary motor, can drive the upper cleaning roller to rotate. At this time, the upper gear will rotate synchronously, that is, it can mesh with the lower gear to make the lower cleaning roller also rotate. The cleaning roller is in contact with the upper and lower surfaces of the return section of the conveyor belt to rotate and clean, which can brush off the particulate material adhering to the surface of the conveyor belt, avoid the material from sticking to the surface of the belt body, affect the working efficiency and service life of the conveyor belt, and ensure the cleanliness of the surface of the conveyor belt.

[0014] 2. This utility model, through the arrangement of an air supply pipe, an air inlet branch pipe, a dust filter box, and an exhaust fan, allows the exhaust fan to pass through the dust filter box. The air supply pipe and air inlet branch pipe draw in gas from inside the pipe housing. Dust or other fine particulate matter brushed off by the cleaning mechanism is drawn into the air supply pipe through the air inlet branch pipe under the negative pressure of the suction. After being conveyed through the air supply pipe, it enters the dust filter box, where the dust particles are blocked by the filter plates and stored. The exhaust fan then discharges clean gas, preventing the dust brushed off by the cleaning mechanism from being re-entrained inside the pipe housing and causing secondary adhesion to the conveyor belt. It also prevents the brushed-off dust from flying out of the pipe housing. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-4 As shown, a pipe-type belt conveyor includes a pipe shell 1. Rollers 2 are rotatably connected to the front and rear ends of the inner surface of the pipe shell 1. A support roller 5 is rotatably connected to the middle of the inner surface of the pipe shell 1. Both the rollers 2 and the support roller 5 are set as concave rollers that are wide at both ends and narrow in the middle. A conveyor belt 3 is sleeved on the surface of the rollers 2. A drive motor 4 is fixedly installed on the right front side of the outer surface of the pipe shell 1. The output shaft end of the drive motor 4 passes through the pipe shell 1 and is connected to the front roller 2. Cleaning mechanisms 6 are provided on the front and rear sides of the lower inner surface of the pipe shell 1.

[0022] By adopting the above technical solution, the drive motor 4 drives the front roller 2 to rotate, which enables the conveyor belt 3 to drive the rear roller 2 to rotate, thereby enabling the entire conveying equipment to carry out normal conveying work.

[0023] The support roller 5 supports the middle section of the conveyor belt 3 to prevent the long-stroke conveyor belt 3 from collapsing when the material it is carrying moves to the middle section.

[0024] The weight of the material can press down on the conveyor belt 3 to conform to the shape of the roller 2, that is, the conveyor belt 3 can be concave to the center to form a concave conveying state, which can prevent the granular material from spilling from both sides of the conveyor belt 3.

[0025] Furthermore, the cleaning mechanism 6 includes a bracket 601 fixedly installed on both the front and rear sides of the bottom of the inner surface of the pipe shell 1. Two cleaning rollers 602 are rotatably installed on the inner side of the bracket 601, and the gap in the middle of the cleaning rollers 602 allows the conveyor belt 3 to pass through.

[0026] By adopting the above technical solution, the cleaning roller 602 rotates in contact with the upper and lower surfaces of the return section of the conveyor belt, which can brush off the material adhering to the surface of the conveyor belt 3.

[0027] Furthermore, the cleaning mechanism 6 also includes gears 603 that are fixedly connected to the right end of the sweeping rollers 602 through the bracket 601 by connecting rods, and the gears 603 mesh with each other. A rotary motor 604 is fixedly installed on the left side of the bracket 601 and is connected to the upper sweeping rollers 602. A transparent protective shell is installed on the outer surface of the bracket 601, and the protective shell covers the gears 603.

[0028] By adopting the above technical solution, the rotary motor 604 can drive the upper cleaning roller 602 to rotate. At this time, the upper gear 603 will rotate synchronously, that is, it can mesh with the lower gear 603 to make the lower cleaning roller 602 also rotate.

[0029] The transparent protective shell can prevent dust or particulate materials brushed off from flying and adhering to the surface of gear 603, thereby preventing gear 603 from being blocked and jammed by materials.

[0030] Furthermore, air supply pipes 7 are fixedly installed on both the left and right sides of the lower inner wall of the pipe shell 1. Air supply pipes 7 are evenly distributed and fixedly connected to the upper surface of the air supply pipes 7, and the upper end of the air supply pipes 8 is connected to the inside of the pipe shell 1. The front end of the air supply pipes 7 is fixedly connected to the same dust filter box 9, and an exhaust fan 10 is fixedly installed on the front side of the outer surface of the dust filter box 9.

[0031] By adopting the above technical solution, the exhaust fan 10 passes through the dust filter box 9 and uses the air supply pipe 7 and the air inlet branch pipe 8 to draw in the gas inside the pipe shell 1. The dust or other types of fine particulate materials brushed off by the cleaning mechanism 6 will enter the air supply pipe 7 through the air inlet branch pipe 8 under the negative pressure of the suction, and then enter the dust filter box 9 through the air supply pipe 7.

[0032] Furthermore, the dust filter box 9 has an openable and closable sealed door on its surface, a filter plate is installed inside, and the exhaust fan 10 is connected to the inside of the dust filter box 9 by a pipe.

[0033] By adopting the above technical solution, the filter plate in the dust filter box 9 can filter particles, collect and store the particles inside the box, and the exhaust fan 10 will discharge the filtered air.

[0034] The dust filter box 9 can be opened using the box door to replace the internal filter plates and clean the collected particulate material.

[0035] Working Principle: When using this pipeline belt conveyor, firstly, the drive motor 4 drives the front roller 2 to rotate, which in turn drives the conveyor belt 3 to rotate the rear roller 2, thus enabling the entire conveying equipment to operate normally. At this time, the material to be conveyed is placed on the surface of the conveyor belt 3. The weight of the material presses down on the conveyor belt 3, conforming to the shape of the roller 2, meaning the conveyor belt 3 can be concave towards the center, forming a concave shape for material conveying. After the conveyor belt 3 unloads the material, the rotary motor 604 drives the upper cleaning roller 602 to rotate. At this time, the upper gear 603 will rotate synchronously, meshing with the lower gear 603, causing the lower cleaning roller 602 to also rotate. The cleaning roller 602 rotates and brushes against the upper and lower surfaces of the return section of the conveyor belt 3, removing the particulate material adhering to the surface of the conveyor belt 3. At the same time, the exhaust fan 10, through the dust filter box 9, uses the air supply pipe 7 and the air inlet branch pipe 8 to draw gas from inside the pipe shell 1. The dust or other fine particulate material brushed off by the cleaning mechanism 6 will enter the air supply pipe 7 through the air inlet branch pipe 8 under the negative pressure of the suction. After being conveyed by the air supply pipe 7, it enters the dust filter box 9. The dust particles are blocked by the filter plate and stored in the dust filter box 9. The exhaust fan 10 will discharge the clean gas. This is the working principle of this pipeline belt conveyor.
