Description

Technical Field

[0001] This utility model belongs to the field of cement denitrification catalyst production technology, and specifically relates to an emergency switching device for the conveying path of an SCR catalyst unit and a material conveying device. Background Technology

[0002] Selective catalytic reduction (SCR) denitrification technology is a core technology for denitrification of flue gas from industrial kilns such as coal-fired boilers in power plants, steel mills, and cement plants. SCR denitrification catalysts are a key component. With increasingly stringent environmental protection requirements, the demand for SCR catalysts is growing, making production efficiency and quality control particularly important.

[0003] Currently, SCR catalyst production commonly employs automated production lines. After the catalyst undergoes extrusion molding and drying, the resulting semi-finished product is typically placed on pallets and transported between processes via conveyor belt systems. These automated production lines significantly improve production efficiency and reduce labor costs. For example, existing conveying mechanisms typically include frames, conveyor chains, and limiting mechanisms for precise pallet positioning.

[0004] However, existing automated production lines have a significant drawback: they typically employ a linear, serial layout. If any equipment in a particular process or any section of the conveyor belt malfunctions, the entire production line may come to a standstill. This not only causes production interruptions and impacts delivery cycles but may also lead to the scrapping of work-in-process, resulting in economic losses. Currently, there is a lack of an emergency switching device capable of quickly removing pallets and their supporting catalyst units from the faulty section when a partial failure occurs, bypassing the faulty part and ensuring continuous production. This significantly limits the reliability and flexibility of the production line.

[0005] Therefore, there is an urgent need to develop an emergency switching device for the conveying path of the SCR catalyst unit and a material conveying device to solve the above-mentioned problems in the existing technology and improve the stability and anti-interference ability of the production line. Utility Model Content

[0006] The purpose of this invention is to provide an emergency switching device for the conveyor path of an SCR catalyst unit and a material conveying device. This device uses a lifting platform to lift the pallet away from the material conveyor belt, and then uses a roller conveyor belt to transfer the pallet and material away from the conveyor belt. This overcomes the defect in existing production lines where a malfunction in any part of the equipment or any section of the conveyor belt can cause the entire production line to stop, resulting in production interruption. The specific technical solution is as follows: An emergency switching device for the conveying path of an SCR catalyst unit is disclosed. The device is located below a material conveyor belt and includes a support frame, a support platform, a first push rod, a lifting platform, a roller conveyor belt, and a control box. The support platform is mounted on top of the support frame and has a through hole. The first push rod is mounted on the support frame, with its output end pointing vertically upward and passing through the through hole. The lifting platform is horizontally mounted on the output end of the first push rod and is located above the support platform. The control box is mounted on the support frame, and the first push rod is electrically connected to the control box. The roller conveyor belt is mounted on top of the lifting platform, and the angle formed between the conveying direction of the roller conveyor belt and the conveying direction of the material conveyor belt is 60-90°.

[0007] Preferably, the conveying direction of the roller conveyor belt is perpendicular to the conveying direction of the material conveyor belt, and the lifting platform is parallel to the support platform.

[0008] Preferably, a second push rod is vertically mounted on one side of the support platform, with the output end of the second push rod facing vertically upward. A baffle is mounted on the output end of the second push rod to block material on the material conveyor belt. A limit switch is mounted on the baffle, and both the limit switch and the second push rod are electrically connected to the control box.

[0009] Preferably, the baffle is covered with a buffer pad, the buffer pad has a clearance hole, the limit switch is located in the clearance hole, and the thickness of the buffer pad is greater than or equal to that of the limit switch.

[0010] Preferably, the support platform has multiple guide holes, and the bottom of the lifting platform is equipped with multiple guide rods. The guide rods are vertical and one end is connected to the bottom of the lifting platform. The guide rods are slidably connected to the guide holes.

[0011] Preferably, it also includes a moving unit, which includes casters, an adjusting support rod, and a support pad. Multiple casters are installed at the bottom of the support frame, one end of the adjusting support rod is connected to the bottom of the support frame, and the support pad is installed at the other end of the adjusting support rod.

[0012] Preferably, the adjusting support rod is provided with scale lines.

[0013] Preferably, it also includes a third push rod, which is disposed on one side of the support frame. The third push rod is horizontally arranged and the output end of the third push rod is parallel to the conveying direction of the roller conveyor belt. The third push rod is used to push the material on the roller conveyor belt to move. The third push rod is electrically connected to the control box.

[0014] A material conveying device includes a material conveyor belt and an emergency switching device for the conveying path of an SCR catalyst unit.

[0015] Compared with existing technologies, this utility model has the following beneficial effects: 1. This utility model activates the first push rod through the control box. The first push rod drives the lifting platform to lift the pallet away from the material conveyor belt. Then, the pallet and material are transferred away from the material conveyor belt by the roller conveyor belt. This allows the operator to bypass the faulty section of the production line and go to the corresponding temporary equipment or the production line without faults for subsequent processing, ensuring the continuous operation of production.

[0016] 2. This utility model uses a second push rod to lift a baffle to block the material on the material conveyor belt. When the pallet triggers the limit switch, the material conveyor belt stops and starts. The first push rod then drives the lifting platform to move upward and move the pallet away from the material conveyor belt, thereby ensuring the relative position of the pallet and the roller conveyor belt and preventing the pallet from tilting due to deviation of the center of gravity.

[0023] 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.

[0024] Next, refer to Figures 1 to 4 The working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model: An emergency switching device for the conveying path of an SCR catalyst unit is disclosed. This device is located below a material conveyor belt 1, which is a chain drive belt powered by a motor. The friction between the chain and the pallet causes the pallet and material to move. Since the chain conveyor belt is typically distributed on both sides with an empty section in the middle, it will not interfere with the emergency switching device for the SCR catalyst unit conveying path.

[0025] The support platform 3 is bolted to the top of the support frame 2. A through hole is provided on the support platform 3. The first push rod 5 is bolted to the support frame 2, with its output end pointing vertically upwards and passing through the through hole. The lifting platform 6 is bolted horizontally to the output end of the first push rod 5, and is positioned above the support platform 3. When the emergency switching device for the SCR catalyst unit's conveyor path is not used, the lifting platform 6 is in contact with the support platform 3. The control box 8 is mounted on the support frame 2 and is used to control the first push rod 5, the second push rod 9, and the material conveyor belt 1.

[0026] The first push rod 5 is electrically connected to the control box 8. The roller conveyor belt 7 is installed on top of the lifting platform 6. When the material conveyor belt 1 moves the pallet above the lifting platform 6, the operator can shut off the material conveyor belt via the controller, and then activate the first push rod 5 to lift the lifting platform 6 away from the material conveyor belt. The operator then uses the roller conveyor belt 7 to push the pallet and material to an adjacent production line or transport vehicle, leaving the material conveyor belt 1. This allows the operator to bypass the faulty section of the production line and proceed to the corresponding temporary equipment or a production line without faults for subsequent processing, ensuring continuous production. After the pallet transfer is complete, the first push rod 5 moves the lifting platform 6 down, and the material conveyor belt 1 restarts to convey the next pallet.

[0027] The angle formed between the conveying direction of the roller conveyor belt 7 and the conveying direction of the material conveyor belt 1 is 60-90°. When the conveying direction of the roller conveyor belt 7 is perpendicular (90°) to the conveying direction of the material conveyor belt 1, the pallet's movement path is the shortest and the working efficiency is the highest. However, depending on the site environment, other corresponding angles can also be selected. The lifting platform 6 is parallel to the support platform 3.

[0028] A second push rod 9 is vertically mounted on one side of the support platform 3 via a push rod bracket and bolts. The output end of the second push rod 9 faces vertically upward. A baffle 4 is mounted on the push rod bolt at the output end of the second push rod 9, and a limit switch 11 is mounted on the baffle 4. Both the limit switch 11 and the second push rod 9 are electrically connected to the control box 8. When the production line malfunctions, the operator can activate the second push rod 9 through the controller. The second push rod 9 moves the baffle 4 upward. At this time, the highest point of the baffle 4 is 5-10cm higher than the highest point of the material conveyor belt 1. When the material conveyor belt 1 moves the pallet, since the baffle 4 is higher than the bottom of the pallet, the pallet will eventually contact the baffle 4 and trigger the limit switch 11. After the limit switch 11 is triggered, the material conveyor belt 1 stops starting, and the first push rod 5 drives the lifting platform 6 upward, moving the pallet away from the material conveyor belt 1. This ensures the relative position of the pallet and the roller conveyor belt 7, preventing the pallet from tilting due to deviation of the center of gravity. The lifting platform 6 rises to a height greater than the top of the baffle 4 to prevent the side wall from rubbing against the baffle 4 and hindering movement when the pallet moves. When the emergency switching device for the SCR catalyst unit conveying path is not needed, the operator activates the second push rod 9 via the controller to move the baffle 4 downward until the top of the baffle 4 is lower than the highest point of the roller conveyor belt 7.

[0029] The first push rod 5 and the second push rod 9 mentioned above are linear drive devices such as electric push rods, hydraulic cylinders, and pneumatic cylinders. If the emergency switching device for the SCR catalyst unit conveying path is fixedly installed below the material conveyor belt 1, hydraulic cylinders and pneumatic cylinders can be used. If the emergency switching device for the SCR catalyst unit conveying path needs to be moved for use depending on the situation, an electric push rod is used to avoid pipeline limitations.

[0030] The baffle 4 is covered with a buffer pad 10, such as a rubber pad or a polymer elastomer, to absorb energy, reduce the impact between the pallet and the baffle 4, and prevent the material on the pallet from shifting due to inertia. The buffer pad 10 has clearance holes, and the limit switch 11 is located in the clearance holes. The thickness of the buffer pad 10 is greater than or equal to that of the limit switch 11, so as to ensure that the buffer pad 10 can function, while also ensuring that the limit switch 11 can be triggered.

[0031] The support platform 3 has multiple guide holes, and the bottom of the lifting platform 6 is equipped with multiple guide rods 12. The guide rods 12 are vertical and one end is connected to the bottom of the lifting platform 6. The guide rods 12 are slidably connected to the guide holes. The guide rods 12 can increase the stability of the lifting platform 6 and prevent the lifting platform 6 from shaking or deforming.

[0032] In another embodiment, the moving unit includes casters 13, an adjusting support rod 14, and a support pad 15. Multiple casters 13 are mounted on the bottom push rod bolts of the support frame 2. One end of the adjusting support rod 14 is threadedly connected to the bottom push rod of the support frame 2. The support pad 15 is installed on the other end of the adjusting support rod 14, and is used to increase friction and stability. The operator can adjust the length of the adjusting support rod 14 by rotating it. When the SCR catalyst unit conveyor path emergency switching device needs to be moved to the section of the conveyor belt before the faulty equipment on the production line, the adjusting support rod 14 is rotated to shorten it until the bottom of the support pad 15 is higher than the bottom of the casters 13, allowing the casters 13 to contact the ground, facilitating the operator to push the SCR catalyst unit conveyor path emergency switching device for relocation. After the SCR catalyst unit conveying path emergency switching device is moved to the target position, the operator rotates and adjusts the support rod 14 to extend it. Once the support pad 15 contacts the ground, the operator needs to use a wrench to rotate and adjust the support rod 14 using the lever principle to raise the SCR catalyst unit conveying path emergency switching device until the casters 13 are no longer in contact with the ground. This ensures that the SCR catalyst unit conveying path emergency switching device will not move during use, causing misalignment. Simultaneously, the operator can adjust the length of the support rod 14 by adjusting the scale on it, ensuring that the lifting platform 6 is parallel to the ground. In this embodiment, because the SCR catalyst unit conveying path emergency switching device needs to move, the first push rod 5 and the second push rod 9 are electric push rods.

[0033] If a fixed SCR catalyst unit conveyor path emergency switching device is used, it needs to be installed at multiple material conveyor belts, resulting in higher equipment costs. However, it can be used quickly in case of emergencies, making it more efficient in handling emergencies. Using a mobile SCR catalyst unit conveyor path emergency switching device requires relocating it to the preceding material conveyor belt after a problem occurs. It also requires commissioning and more preparation time, resulting in lower efficiency, but the equipment cost is also lower. The choice can be made based on the actual situation.

[0034] In another embodiment, the third push rod is positioned on one side of the support frame 2. The third push rod is horizontally positioned, and its output end is parallel to the conveying direction of the roller conveyor belt 7. The third push rod is used to move the material on the roller conveyor belt 7 and is electrically connected to the control box 8. Moving the pallet on the roller conveyor belt 7 by the third push rod replaces manual pushing, further improving efficiency. However, it is important to ensure that the output end of the third push rod contacts the pallet but not the lifting platform 6 to avoid interference.

[0035] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings.
