Abstract

This utility model discloses an SCR denitrification device with a filter element anti-loosening structure, relating to the field of SCR denitrification device technology. It includes an inlet pipe, an oil-gas separator, a connecting pipe, an mounting sleeve, and a filter element body. One end of the inlet pipe is equipped with an oil-gas separator, and one side of the oil-gas separator is equipped with a connecting pipe. The surface of the connecting pipe is equipped with a mounting sleeve. The output of a motor drives a connecting rod to move, which in turn drives a limiting block to move. This limiting block restricts the filter element body during movement, preventing it from loosening. This provides the SCR denitrification device with good anti-loosening performance during use. The vertical plate moves the filter screen into the fixed frame, and then the rotating rod is rotated, pulling the vertical rod and horizontal rod together. This allows the filter screen to be quickly installed inside the fixed frame, thereby filtering dust in the flue gas and preventing dust from harming the environment.

Description

Technical Field

[0001] This utility model relates to the field of SCR denitrification technology, specifically an SCR denitrification device with a filter element anti-loosening structure. Background Technology

[0002] SCR (Selective Catalytic Reduction) denitrification is a technology that uses ammonia or other suitable reducing agents injected into flue gas to convert NOx into nitrogen and water using a catalyst. This technology is widely used in industrial flue gas denitrification in power plants and incinerators, as well as in diesel vehicle exhaust purification. However, current SCR denitrification devices still have some shortcomings, such as:

[0003] When using existing SCR denitrification devices, the filter elements inside the SCR denitrification device are directly installed, which makes it easy for the filter elements to become misaligned during the installation process. This causes slight deviations between the filter element and the mounting base, which makes the filter element prone to shaking inside when filtering flue gas, thus making the filter element prone to loosening. Utility Model Content

[0004] The purpose of this invention is to provide an SCR denitrification device with a filter element anti-loosening structure to solve the problem of poor anti-loosening effect of SCR denitrification devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an SCR denitrification device with a filter element anti-loosening structure, comprising an air inlet pipe, an oil-gas separator, a connecting pipe, a mounting sleeve, and a filter element body. An oil-gas separator is located at one end of the air inlet pipe, and a connecting pipe is located on one side of the oil-gas separator. A mounting sleeve is located on the surface of the connecting pipe, and the filter element body is located inside the mounting sleeve. An anti-loosening mechanism is located at the bottom of the mounting sleeve. The anti-loosening mechanism includes a mounting frame, a motor, and a rotating rod. A mounting frame is located at the bottom of the mounting sleeve, and a motor is mounted at the bottom of the mounting frame. The output end of the motor is connected via a coupling to a rotating rod extending into the mounting frame.

[0006] Preferably, the bottom end inside the mounting frame is connected to a bidirectional screw via a bearing, and a bevel gear set is connected between the bidirectional screw and the rotating rod.

[0007] Preferably, the surface of the bidirectional screw is threaded with symmetrically distributed threaded blocks, and one end of each of the two threaded blocks is provided with a connecting rod.

[0008] Preferably, a limit block is provided on the side of the connecting rod near the filter element body.

[0009] Preferably, a filtering mechanism is provided at one end of the connecting pipe. The filtering mechanism includes a fixed frame, a docking seat, a vertical plate, a filter screen, a horizontal bar, a rotating shaft, a rotating rod, a vertical bar, a T-shaped rod, and a spring. The fixed frame is provided on the surface of one end of the connecting pipe.

[0010] Preferably, the fixed frame has a docking seat inside and a vertical plate on one side.

[0011] Preferably, a filter screen extending into the docking seat is provided on one side of the vertical plate, and the filter screen is evenly distributed on one side of the vertical plate.

[0012] Preferably, the vertical plate has symmetrically distributed horizontal bars on the side away from the filter screen, and both ends of the fixed frame are provided with pivots, with rotating rods provided on the surface of the pivots.

[0013] Preferably, a vertical rod is provided on one side of the rotating rod, and a T-shaped rod extending outward is provided inside the rotating rod, with one side of the T-shaped rod welded to the vertical rod.

[0014] Preferably, a spring is welded between the T-shaped rod and the rotating rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The SCR denitrifier with filter element anti-loosening structure can drive the connecting rod to move through the output end of the motor. At the same time, the connecting rod can drive the limiting block to move when it moves, so that the limiting block can limit the filter element body when it moves, preventing the filter element body from becoming loose. This gives the SCR denitrifier a better limiting and anti-loosening effect during use. The vertical plate moves the filter screen into the fixed frame, and then the rotating rod is rotated, and then the vertical rod is pulled to connect with the horizontal rod, so that the filter screen can be quickly installed in the fixed frame, thereby filtering the dust in the flue gas and preventing the dust in the flue gas from causing harm to the environment.

[0016] 1. This SCR denitrifier with a filter element anti-loosening structure, when the motor is started, the output end of the motor can drive the rotating rod to rotate. When the rotating rod rotates, it drives the bevel gear set to rotate. At the same time, when the bevel gear set rotates, it drives the double-headed screw to rotate. When the double-headed screw rotates, it drives the threaded block to move. When the threaded block moves, it drives the connecting rod to move. When the connecting rod moves, it drives the limiting block to move. When the limiting block moves, it limits the filter element body and prevents the filter element body from loosening. This gives the SCR denitrifier a good limiting and anti-loosening effect during use.

[0017] 2. This SCR denitrification unit with an anti-loosening filter structure moves the vertical plate and filter screen into the fixed frame, allowing one side of the filter screen to engage with the docking seat. Then, rotating the rotating rod and pulling the vertical rod causes the T-shaped rod to move, compressing the spring and allowing the vertical rod to dock with the horizontal rod. This allows the filter screen to be quickly installed inside the fixed frame, effectively filtering dust from the flue gas and preventing dust from harming the environment. Reversing the operation allows the filter screen to be quickly removed from the fixed frame for easy cleaning, preventing internal blockage caused by prolonged use. Attached Figure Description

[0025] Please see Figures 1-3It is understood that this utility model provides a technical solution: an SCR denitrification device with a filter element anti-loosening structure, including an air inlet pipe 1, an oil-gas separator 2, a connecting pipe 3, a mounting sleeve 4, and a filter element body 5. The oil-gas separator 2 is located at one end of the air inlet pipe 1, and the connecting pipe 3 is located on one side of the oil-gas separator 2. The mounting sleeve 4 is located on the surface of the connecting pipe 3, and the filter element body 5 is located inside the mounting sleeve 4. An anti-loosening mechanism 6 is located at the bottom of the mounting sleeve 4. The anti-loosening mechanism 6 includes a mounting frame 601, a motor 602, and a rotating rod 603. A mounting bracket is located at the bottom of the mounting sleeve 4. The mounting frame 601 has a motor 602 mounted at its bottom. The output end of the motor 602 is connected to a rotating rod 603 extending into the mounting frame 601 via a coupling. The bottom end of the mounting frame 601 is connected to a double-acting screw 604 via a bearing. A bevel gear set 605 is connected between the double-acting screw 604 and the rotating rod 603. Symmetrically distributed threaded blocks 606 are threaded onto the surface of the double-acting screw 604. A connecting rod 607 is provided at one end of each of the two threaded blocks 606. A limit block 608 is provided on the side of the connecting rod 607 near the filter element body 5.

[0026] See Figures 1-3 It can be seen that the output end of the motor 602 can drive the connecting rod 607 to move. At the same time, when the connecting rod 607 moves, it can drive the limiting block 608 to move, so that the limiting block 608 can limit the filter element body 5 when it moves, preventing the filter element body 5 from becoming loose, so that the SCR denitrifier can have a good limiting and anti-loosening effect when in use.

[0027] See Figure 1 , Figure 2 , Figure 4 and Figure 5 It is known that a filter mechanism 7 is provided at one end of the connecting pipe 3. The filter mechanism 7 includes a fixed frame 701, a docking seat 702, a vertical plate 703, a filter screen 704, a horizontal bar 705, a rotating shaft 706, a rotating rod 707, a vertical rod 708, a T-shaped rod 709, and a spring 710. The fixed frame 701 is provided on the surface of one end of the connecting pipe 3. The docking seat 702 is provided inside the fixed frame 701. The vertical plate 703 is provided on one side of the fixed frame 701. The filter screen 704 extending into the docking seat 702 is provided on one side of the vertical plate 703. The filter screen 704 is evenly distributed on one side of the vertical plate 703. The side of the vertical plate 703 away from the filter screen 704 is provided with symmetrically distributed horizontal bars 705. Both ends of the fixed frame 701 are provided with rotating shafts 706. The surface of the rotating shaft 706 is provided with a rotating rod 707. A vertical rod 708 is provided on one side of the rotating rod 707. A T-shaped rod 709 extending to the outside is provided inside the rotating rod 707. One side of the T-shaped rod 709 is welded to the vertical rod 708. A spring 710 is welded between the T-shaped rod 709 and the rotating rod 707.

[0028] See Figure 1 , Figure 2 , Figure 4 and Figure 5 It can be seen that by moving the vertical plate 703 to move the filter screen 704 into the fixed frame 701, then rotating the rotating rod 707, and then pulling the vertical rod 708 to connect with the horizontal rod 705, the filter screen 704 can be quickly installed inside the fixed frame 701, thereby filtering the dust in the flue gas and preventing the dust in the flue gas from causing harm to the environment.

[0029] In summary, SCR denitrification is a selective catalytic reduction denitrification technology. When the filter element body 5 inside the SCR denitrification unit is prone to loosening, starting the motor 602 causes the output end of the motor 602 to drive the rotating rod 603, the bevel gear set 605, and the double-acting screw 604 to rotate. When the double-acting screw 604 rotates, it drives the threaded block 606 to move. When the threaded block 606 moves, it drives the connecting rod 607 to move. At the same time, when the connecting rod 607 moves, it drives the limiting block 608 to move. When the limiting block 608 moves, it limits the filter element body 5, preventing the filter element body 5 from loosening. This gives the SCR denitrification unit a good limiting and anti-loosening effect during use.
