Description

Technical Field

[0001] The invention relates to the technical field of particle conveying, and in particular to a PTFE (polytetrafluoroethylene) particle conveying device. Background Art

[0002] PTFE (polytetrafluoroethylene) particles are made of polytetrafluoroethylene through a granulator. They have extremely strong corrosion resistance and hardly react with any chemical substances. They can be made into plates, pipes, pipelines, valves and other equipment. They can effectively resist the erosion of various strong acids, strong alkalis, organic solvents and other chemical media, ensuring the safety and stability of the chemical production process.

[0003] During the processing of polytetrafluoroethylene particles, they need to be transferred and transported to the next processing area through a conveying device. Common conveying methods include pneumatic conveying, mechanical screw conveying and belt conveying. Belt conveyors are easy to maintain and manage, with low failure rates, which can reduce operating costs and improve production efficiency. Specially treated belts (such as polytetrafluoroethylene-coated belts) are usually used. Such belts have the advantages of wear resistance, anti-adhesion, and easy cleaning, which can reduce material loss and pollution during transportation. When using belt conveyors, materials are fed from one end, and the belt tilts upward to transport the materials to the other end, lift the materials, and enter the next equipment for processing through the discharge pipe. The materials fall from the other end into the discharge pipe, and the middle needs to be closed to prevent them from spilling everywhere. When the materials are discharged into the discharge pipe, such as Figure 6 As shown, the material will flow back to the other side, affecting the use effect. Summary of the invention

[0004] The present invention is to overcome the shortcomings of the above-mentioned prior art and provide a PTFE (polytetrafluoroethylene) particle conveying device. The present invention feeds polytetrafluoroethylene particles into a conveyor belt through a feed port, and is lifted to the other end by the conveyor belt. A partition is provided on the conveyor belt to better transport the material. The conveyor belt is tilted to both sides at the discharge port, and enters the discharge pipe from the discharge ports on both sides of the conveyor belt, and then enters the next equipment for processing, so as to avoid the material from being fed back to the other side when discharging from one end of the conveyor belt, which is not easy to use.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a PTFE (polytetrafluoroethylene) particle conveying device, including a conveyor belt that circles around and a driving mechanism for driving the conveyor belt to rotate, and a plurality of partitions are circumferentially spaced on the conveyor belt; a feed port is provided at the front end of the conveyor belt, and discharge ports are provided on both sides of the rear end of the conveyor belt, the conveyor belt is inclined to both sides at the discharge port, and the discharge port is connected to a feed pipe.

[0006] Preferably, a cover plate is provided on the upper side of the partition, and baffles are provided on both sides of the cover plate.

[0007] Preferably, the driving mechanism includes a driven roller and a driving roller located at the left and right sides below, and a rotating roller located at the top.

[0008] Preferably, two rotating rollers are provided, and the two rotating rollers are arranged side by side with an interval, and the rotating rollers are high in the middle and low on both sides.

[0009] Preferably, a fixed block is provided in the middle of the bottom side of the partition, the fixed block is fixed on the conveyor belt, the bottom side of the partition is provided with accommodating grooves on both sides of the fixed block, the conveyor belt is provided with an arc-shaped piece at the accommodating groove, and the arc-shaped piece is slidably arranged in the accommodating groove.

[0010] Preferably, the upper conveyor belt is provided with a bottom plate on its lower side.

[0011] Preferably, the conveyor belt located below is provided with a lower plate on its lower side.

[0012] Preferably, a hopper is provided on the feed inlet.

[0013] Preferably, the feed port is provided with a side cover plate on one side of the conveyor belt at the driven roller, and the length of the side cover plate is greater than the distance between two adjacent partitions.

[0014] Preferably, the discharge port is provided with collecting boxes located on both sides of the conveyor belt, and the discharge port is connected to the discharge pipe through the collecting boxes.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:

[0016] (1) The polytetrafluoroethylene particles are fed into the conveyor belt through the feed port and lifted to the other end by the conveyor belt. The conveyor belt is provided with a partition to better transport the material. The conveyor belt is tilted to both sides at the discharge port, and enters the discharge pipe from the discharge ports on both sides of the conveyor belt, and then enters the next equipment for processing, so as to avoid the material being fed back to the other side when unloading from one end of the conveyor belt, which affects the use effect.

[0017] (2) A cover plate is provided on the upper side of the partition, and baffles are provided on both sides of the cover plate, forming a closed conveying environment, which can block the upper side and both sides of the partition on the conveyor belt, effectively preventing the materials on the conveyor belt from sliding off the upper side or both sides of the partition due to vibration or external force during the conveying process. This ensures that the items can reach the predetermined location safely and accurately, and improves the conveying effect.

[0018] (3) The entire conveyor belt is driven by the driving roller to rotate, and the driven roller serves as a support to ensure the stable operation of the conveyor belt; the two rotating rollers, which are high in the middle and low on both sides, can make the conveyor belt between them tilt to both sides under the influence of the material and its own gravity, and flow the material to the discharge ports on both sides, so as to achieve the effect of the conveyor belt tilting to both sides at the discharge port and the material falling. No additional equipment or operation is required, which greatly simplifies the production process and cost, maximizes the use of space resources, reduces the floor space, and reduces production costs.

[0019] (4) When the conveyor belt passes through the rotating roller and tilts to both sides, a gap will be left between the two sides and the partition due to the connection with the fixed block in the middle. At this time, the arc-shaped sheet, driven by the conveyor belt, slides out of the receiving groove on the bottom side of the partition to block this part of the gap and prevent the material from sliding around.

[0020] (5) When the conveyor belt is transporting materials, the upper conveyor belt is provided with a bottom plate on its lower side to support the conveyor belt, so as to prevent the conveyor belt from tilting to both sides under the influence of the materials and its own gravity before reaching the discharge port, thereby affecting the transportation of the materials.

[0021] (6) The partition of the conveyor belt below faces downward and is connected to the conveyor belt only by the fixed block in the middle. When the fixed block is pulled under the influence of the gravity of the partition and acts on the conveyor belt, the middle of the conveyor belt will drop accordingly, forming a V shape. The tighter the conveyor belt is, the easier it is for the arc-shaped pieces on both sides to slide out of the receiving groove completely due to the drop in the middle, making it difficult to align and enter, affecting the use of the conveyor belt. The conveyor belt located below is provided with a lower plate on its lower side, which can block the partition to prevent it from dropping due to gravity.

[0022] (7) The material is poured from the hopper on the feed port and enters the feed port. When one partition enters the feed port and the other does not, the material will enter the conveyor belt between the two. A side cover plate is provided on one side. The length of the side cover plate is designed to be greater than the distance between two adjacent partitions to prevent the material from sliding outward from the space between the two.

[0023] (8) The material enters the collection box located on both sides of the conveyor belt. The collection box is connected to the discharge pipe and enters the next equipment for processing through the discharge pipe, thus enclosing the transportation and protecting the material.

[0037] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0038] Example

[0039] The following is combined with Figure 1-5 The present invention is further described, a PTFE (polytetrafluoroethylene) particle conveying device, such as Figure 1-3 As shown, it includes a conveyor belt 1 that is wound around a circle and a driving mechanism 2 for driving the conveyor belt 1 to rotate, and a plurality of partitions 11 are circumferentially spaced on the conveyor belt 1; a feed port 3 is provided at the front end of the conveyor belt 1, and discharge ports 4 are provided on both sides of the rear end of the conveyor belt 1. The conveyor belt 1 is inclined to both sides at the discharge port 4, and the discharge port 4 is connected to a discharge pipe 41.

[0040] The polytetrafluoroethylene particles are fed into the conveyor belt 1 through the feed port 3 and lifted to the other end by the conveyor belt 1. The conveyor belt 1 is provided with a partition 11 to better transport the materials. The conveyor belt 1 is tilted to both sides at the discharge port 4, and enters the discharge pipe 41 from the discharge ports 4 on both sides of the conveyor belt 1, and then enters the next equipment for processing, so as to avoid the material being returned to the other side when discharging from one end of the conveyor belt 1, which affects the use effect.

[0041] like Figure 2 and 3 As shown, a cover plate 5 is provided on the upper side of the partition 11, and baffles 51 are provided on both sides of the cover plate 5, forming a closed conveying environment, which can block the upper side and both sides of the partition 11 on the conveyor belt 1, and effectively prevent the materials on the conveyor belt 1 from sliding off the upper side or both sides of the partition 11 due to vibration or external force during the conveying process. Ensure that the items can reach the predetermined position safely and accurately, and improve the conveying effect.

[0042] like Figure 1 , 3 As shown in FIG. 5 , the driving mechanism 2 includes a driven roller 22 and a driving roller 21 located at the left and right sides below, and a rotating roller 23 located at the top. Two rotating rollers 23 are provided, and the two rotating rollers 23 are arranged side by side at intervals, and the rotating rollers 23 are high in the middle and low on both sides.

[0043] The entire conveyor belt 1 is driven to rotate by the driving roller 21, and the driven roller 22 serves as a support to ensure the stable operation of the conveyor belt; the two rotating rollers 23, which are high in the middle and low on both sides, can make the conveyor belt 1 between the two tilt to both sides under the influence of the material and its own gravity, and flow the material to the discharge ports 4 on both sides, so as to achieve the effect of the conveyor belt 1 tilting to both sides at the discharge ports 4 and dropping the material. No additional equipment or operation is required, which greatly simplifies the production process and cost, maximizes the use of space resources, reduces the floor space, and reduces production costs.

[0044] like Figure 3 and 5 As shown, a fixed block 13 is provided in the middle of the bottom side of the partition 12, and the fixed block 13 is fixed on the conveyor belt 1. The bottom side of the partition 12 is provided with a receiving groove 12 on both sides of the fixed block 13, and the conveyor belt 1 is provided with an arc piece 14 at the receiving groove 12, and the arc piece 14 is slidably set in the receiving groove 12.

[0045] When the conveyor belt 1 passes through the rotating roller 23 and tilts to both sides, a gap is left between it and the partition 12. Driven by the conveyor belt 1, the arc-shaped piece 14 slides out of the receiving groove 12 to block this gap and prevent the material from sliding around.

[0046] like Figure 1 As shown, the conveyor belt 1 located above is provided with a bottom plate 15 on its lower side to support the conveyor belt 1 when the conveyor belt 1 transports materials, so as to prevent the conveyor belt 1 from tilting to both sides under the influence of the materials and its own gravity before reaching the discharge port 4, thereby affecting the transportation of the materials.

[0047] like Figure 1As shown, the conveyor belt 1 located below is provided with a lower plate 16 on its lower side. The partition plate 11 of the conveyor belt 1 below faces downward, and is connected to the conveyor belt 1 only through the fixed block 13 in the middle. When the fixed block 13 is pulled under the influence of the gravity of the partition plate 11 and acts on the conveyor belt 1, the middle of the conveyor belt 1 will drop accordingly, forming a V shape. Where the conveyor belt 1 is more taut, it is more likely that the arc-shaped pieces 14 on both sides will completely slide out of the receiving groove 12 due to the drop in the middle, making it difficult to align and enter, affecting the use of the conveyor belt 1. The lower plate 16 can block the partition plate 11 to prevent it from dropping due to the influence of gravity.

[0048] like Figure 1 and 4 As shown, a hopper 31 is provided on the feed port 3 , and a side cover plate 32 is provided on one side of the conveyor belt 1 at the driven roller 22 of the feed port 3 , and the length of the side cover plate 32 is greater than the distance between two adjacent partitions 11 .

[0049] The material is poured from the hopper 31 and enters the feed port 3. When one partition 11 enters the feed port 3 and the other does not, the material will enter the conveyor belt 1 between the two. The length of the side cover plate 32 is set longer to prevent the material from sliding outward from the space between the two.

[0050] like Figure 2 and 3 As shown, the discharge port 4 is provided with a collecting box 42 located on both sides of the conveyor belt 1, and the discharge port 4 is connected to the discharge pipe 41 through the collecting box 42. The material enters the collecting box 42 and then enters the next equipment for processing through the discharge pipe 41, so as to transport and protect the material in a closed manner.
