Description

Technical Field

[0001] This utility model relates to the field of electrostatic precipitator technology, and in particular to an adaptive adjustment mechanism for the electrode spacing of an electrostatic precipitator. Background Technology

[0002] An electrostatic precipitator is a device that uses an electric field to separate and collect dust from an airflow. It is widely used in industrial production, especially in power plants, cement plants, steel mills, and chemical plants, to remove fine dust from exhaust gases, achieving air purification and meeting environmental emission standards.

[0003] Based on the above, the inventors have discovered the following problems: During the use of existing electrostatic precipitators, due to the continuous dynamic changes in flue gas composition and dust load, the electrode spacing of the electrostatic precipitator needs to be adjusted according to different dust concentrations. However, most existing equipment relies on manual adjustment or periodic inspection for adjustment, lacking adaptive adjustment capabilities. Manual adjustment not only results in low maintenance efficiency but also significantly reduces dust removal efficiency, thereby affecting the overall operating efficiency of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive adjustment mechanism for the electrode spacing of an electrostatic precipitator, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adaptive adjustment mechanism for the electrode spacing of an electrostatic precipitator includes a pair of mounting seats, a pair of mounting bases fixed between the top ends of the pair of mounting seats, a plurality of mounting plates arranged in a row between the pair of mounting bases and between the bottom ends of the pair of mounting bases, and electrode plates mounted on the mounting plates.

[0007] The bottom surface of the mounting base is provided with a sliding groove, and a movable block that corresponds to the mounting plate one by one slides in the sliding groove. The movable block is fixedly connected to the corresponding mounting plate.

[0008] At least one mounting base is provided with an adjustment assembly, the adjustment assembly comprising:

[0009] A slide rod fixed inside the mounting base and parallel to the slide groove.

[0010] A fixed seat and several sliding seats are fitted onto the slide rod, wherein the fixed seat is fixed to the slide rod, and the sliding seats are slidably engaged with the slide rod.

[0011] The scissor linkage has each intersection node hinged to a corresponding slide or fixed seat.

[0012] A lead screw, rotatably supported within the mounting base and parallel to the slide rod,

[0013] A connecting rod is fixed on a slide opposite to the fixed base, and the connecting rod is threadedly engaged with a lead screw;

[0014] The mounting base is equipped with an external motor that drives the lead screw to rotate, and the motor is controlled by a control panel.

[0015] A dust concentration sensor and a current sensor are installed on the dust inlet side of an assembly base. Both sensors output signals to the control panel. The control panel starts and stops the motor according to the changes in dust concentration and current, so as to automatically and synchronously adjust the electrode spacing.

[0016] The height of the mounting slot is greater than the maximum height of the scissor link when it is fully folded, and the length of the mounting slot is greater than the maximum length of the scissor link when it is fully extended.

[0017] The bottom inner side of the mounting base is provided with a slide rail parallel to the slide groove, and the lower two sides of the mounting plate are fixed with sliders that slide in cooperation with the slide rail.

[0018] The motor output shaft is coaxially connected to the lead screw via a coupling, and the motor housing is fixed to the end wall of the mounting base.

[0019] The dust concentration sensor and current sensor are connected to the analog input port of the control panel via shielded cables, and the drive output port of the control panel is connected to the motor power supply circuit via relays, forming a closed-loop control circuit.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] 1) By rotating the lead screw, the connecting rod drives a sliding block to slide while a fixed block remains stationary. This can change the angle of the scissor linkage, causing several sliding blocks to move simultaneously on the sliding rod. When the included angle of the scissor linkage increases, the sliding blocks move closer together, reducing the distance between the mounting plates. When the included angle of the scissor linkage decreases, the sliding blocks move further apart, increasing the distance between the mounting plates. This allows for quick adjustment of the spacing between each mounting plate, effectively improving work efficiency.

[0022] 2) A dust concentration sensor is used to measure the dust load inside the electrostatic precipitator, and a current sensor is used to monitor the current changes of the electrostatic precipitator. The dust concentration sensor and the current sensor transmit signals to the control panel, and the control panel sends a command to the motor to start the motor and drive the lead screw to rotate, so that the slide can drive the mounting plate to adjust the spacing. There is no need to rely on manual adjustment or periodic inspection for adjustment, which enhances the adaptive adjustment capability and greatly improves the dust removal efficiency.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] like Figure 1-4 As shown, this utility model provides an adaptive adjustment mechanism for the electrode spacing of an electrostatic precipitator, including a pair of mounting seats 1, a pair of mounting bases 2 installed at the top of the pair of mounting seats 1, and several mounting plates 3 movably installed between the pair of mounting bases 2 and between the bottom ends of the pair of mounting seats 1. The bottom ends of the pair of mounting bases 2 are provided with sliding grooves 11, and several moving blocks 10 are slidably installed in the sliding grooves 11. The moving blocks 10 are connected to the mounting plates 3. Several electrode plates 4 are installed between the two ends of the mounting plates 3. An adjustment component is installed on the mounting base 2. A dust concentration sensor 5 and a current sensor 6 are installed at the dust inlet position of one of the mounting bases 1. A control panel 19 is installed on one side of one of the mounting bases 1. The dust concentration sensor 5 is used to measure the dust load in the electrostatic precipitator, and the current sensor 6 is used to monitor the current change of the electrostatic precipitator.

[0031] The adjusting assembly includes a mounting groove 7 disposed within the mounting base 2. A pair of sliding rods 8 are mounted within the mounting groove 7. Several sliding seats 9 and a fixed seat 20 are mounted on the pair of sliding rods 8. The pair of sliding rods 8 pass through the several sliding seats 9, and the several sliding seats 9 are slidably connected to the pair of sliding rods 8. A fixed seat 20 is fixedly connected to the pair of sliding rods 8. A scissor-type connecting rod 12 is rotatably mounted on the several sliding seats 9 and the fixed seat 20 via a hinge. The bottom ends of the several sliding seats 9 and the fixed seat 20 are all connected to... The movable block 10 is connected and slides through a slide block 9 while being held in place by a fixed seat 20. This allows the angle of the scissor linkage 12 to change, causing several slide blocks 9 to move simultaneously on the slide rod 8. When the included angle of the scissor linkage 12 increases, the slide blocks 9 move closer together, reducing the distance between the mounting plates 3. When the included angle of the scissor linkage 12 decreases, the slide blocks 9 move further apart, increasing the distance between the mounting plates 3. This allows for quick adjustment of the spacing between each mounting plate 3, effectively improving work efficiency.

[0032] A connecting rod 15 is installed on a slide 9 at a relative position of the fixed base 20. An installation block 13 is installed at the top of the installation groove 7. A lead screw 14 is rotatably installed between the installation block 13 and the installation groove 7. The lead screw 14 passes through the connecting rod 15 and is threadedly connected to it. The rotation of the lead screw 14 drives the connecting rod 15 to move, and the connecting rod 15 drives one slide 9 to move, thereby moving several slides 9 at the same time. This effectively saves manpower, eliminates the need for manual adjustment of the spacing one by one, and greatly improves maintenance efficiency.

[0033] The height of the mounting groove 7 is greater than the longitudinal combined height of the scissor link 12, and the length of the mounting groove 7 is greater than the lateral combined length of the scissor link 12. Because the height of the mounting groove 7 is greater than the longitudinal combined height of the scissor link 12, and the length of the mounting groove 7 is greater than the lateral combined length of the scissor link 12, it is convenient for the scissor link 12 to extend and retract within the mounting groove 7, thus improving its practicality.

[0034] The mounting base 2 has a motor 16 installed on its outer side. The output end of the motor 16 is connected to one end of the lead screw 14 via a coupling. The motor 16 is electrically connected to the control panel 19. The motor 16 drives the lead screw 14 to rotate, which effectively saves manpower and improves work efficiency.

[0035] Each pair of mounting bases 1 is provided with a slide rail 18 at its bottom end. Several mounting plates 3 are equipped with sliders 17 on both sides at the bottom end of the mounting base 1. The sliders 17 are slidably connected to the slide rails 18. Through the sliding connection between the sliders 17 and the slide rails 18, when the mounting plate 3 at the top of the mounting base 1 moves, it drives the electrode plate 4 to move, and at the same time drives the mounting plate 3 at the bottom of the mounting base 1 to move, so as to facilitate the adjustment of the distance between the electrode plates 4.

[0036] The dust concentration sensor 5 and the control panel 19 are connected for signal transmission. The current sensor 6 is also connected for signal transmission to the control panel 19. The dust concentration sensor 5 is used to measure the dust load inside the electrostatic precipitator, and the current sensor 6 is used to monitor the current changes of the electrostatic precipitator. The dust concentration sensor 5 and the current sensor 6 transmit signals to the control panel 19, which then sends a command to the motor 16 to start the motor 16 and drive the lead screw 14 to rotate. This causes the slide 9 to adjust the spacing of the mounting plate 3, eliminating the need for manual adjustment or periodic inspections. This enhances the adaptive adjustment capability and significantly improves the dust removal efficiency.

[0037] The specific usage and function of this embodiment are as follows:

[0038] First, check the integrity of the device. Only after confirming it is correct can it be used. During use, dust concentration sensor 5 measures the dust load inside the electrostatic precipitator, and current sensor 6 monitors changes in the current of the electrostatic precipitator. When the concentration at the inlet rises, dust concentration sensor 5 transmits a signal to control panel 19. Control panel 19 sends a command to motor 16, starting motor 16 and driving lead screw 14 to rotate. The rotation of lead screw 14 causes connecting rod 15 to slide a slide block 9, while a fixed seat 20 remains fixed. This can cause the angle of scissor-type connecting rod 12 to change, allowing several slide blocks 9 to move simultaneously. As the slide bar 8 moves, the included angle of the scissor linkage 12 increases, causing the slide block 9 to move the moving blocks 10 closer together, thus reducing the distance between the mounting plates 3. At the same time, the mounting plates 3 at the bottom of the mounting base 1 move by sliding connection between the slider 17 and the slide rail 18. Reducing the spacing can enhance the electric field strength and increase the dust driving speed. It can also quickly adjust the spacing between each mounting plate 3, effectively improving work efficiency. It does not require manual adjustment or periodic inspection, enhancing the adaptive adjustment capability and significantly improving dust removal efficiency. This device has a novel overall design and simple structure, and is therefore worthy of widespread promotion and use.
