A fly ash treatment filter

Abstract

This invention provides a fly ash treatment filter, relating to the field of fly ash treatment filtration technology. It includes a housing, with a support plate fixedly installed inside the housing, and a storage bin fixedly installed on the top of the outer surface of the housing. In this invention, fly ash is filtered by the filter plate and then discharged through an exhaust channel. The filter plate is secured to the bottom end of a multi-section rod by a Y-shaped locking post at its bottom. The Y-shaped locking post is connected to the bottom end of the multi-section rod by locking onto a round shaft at the bottom of the multi-section rod. The Y-shaped locking post is made of deformable soft rubber. Driven by an external power source, the rotating shaft rotates, causing the multi-section rod to rotate and supporting the filter plate, moving it up and down. This support rather than pulling is necessary. When replacement is required after a period of use, the filter plate on one side is lowered, and the other side is raised for replacement. The Y-shaped locking post disconnects from the round shaft at the bottom of the multi-section rod and falls onto the surface of the soft rubber protective base, thus completing the filter plate replacement.

Description

Technical Field

[0001] This invention relates to the field of fly ash treatment and filtration technology, and in particular to a fly ash treatment filter. Background Technology

[0002] Fly ash, also known as fly ash or flue ash, is an industrial solid waste discharged from power plants after coal combustion. It consists of fine ash particles with a small diameter that are captured in the flue gas after coal combustion. With the rapid development of the power industry, fly ash emissions have increased year by year, becoming one of the largest industrial waste emissions in my country. If such a large amount of fly ash is not treated, it will generate dust and cause air pollution. To avoid pollution, fly ash needs to be filtered. Power plants generally use fly ash filtration machines to treat fly ash.

[0003] However, in existing technologies, the filter screens used in fly ash treatment filters need to be cleaned and replaced regularly. For example, a Chinese patent discloses a fly ash treatment and filtration device, including a filter body, a support, and a positioning component. The filter body is connected to the support via a buffer spring. The filter body is a hollow cuboid structure with openings on both sides. Multiple grooves are provided inside the filter body along its length. Multiple-stage filter components are slidably connected within the grooves and positioned and fixed by the positioning component. A vibration motor is installed on the filter body. This invention, by setting up grooves, multiple-stage filter components, a positioning component, and a vibration motor, can, on the one hand, perform graded filtration of fly ash and shake off unfiltered fly ash particles from the filter screen, preventing filter clogging and avoiding safety hazards. On the other hand, it facilitates the installation, disassembly, and cleaning of the multi-stage filter components, making it flexible in use and easy to maintain later.

[0004] While the above solution has the advantages mentioned above, its disadvantage is that even with the vibration mechanism installed, the filter plate still needs to be replaced after long-term use. The replacement of the filter plate requires manual operation, which involves turning the handle to remove the threaded rod and then removing the filter plate for replacement, making the operation quite cumbersome. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that in the prior art, the replacement of filter plates still requires manual operation, which involves turning the handle to remove the threaded rod and then removing the filter plate for replacement, making the operation cumbersome.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fly ash treatment filter, comprising: a casing, a support plate fixedly installed inside the casing, a storage bin fixedly installed on the top of the outer surface of the casing, multiple soft rubber protective bases movably installed on the bottom of the inner wall of the casing, a partition plate fixedly installed on the bottom of the inner wall of the casing, the soft rubber protective bases being movably connected to the partition plate, a rotating shaft movably installed on one side of the inner wall of the casing, multiple multi-section rods fixedly sleeved on the outer surface of the rotating shaft, multiple slotted plates fixedly embedded inside the support plate, a Y-shaped locking post movably sleeved on one end of the outer surface of each of the multiple multi-section rods, a filter plate fixedly installed on one end of the outer surface of each of the multiple Y-shaped locking posts, multiple counterweight sliders fixedly installed on one side of the outer surface of each of the multiple filter plates, and a limiting block fixedly installed on the other side of the outer surface of each of the multiple filter plates, the limiting block being slidably embedded in the inner wall of the slotted plate, and one side of the counterweight slider being slidably embedded in the inner wall of the slotted plate.

[0007] In a preferred embodiment, a plurality of rotating rods are movably mounted on one side of the inner wall of the housing, and limit plates are fixedly mounted on the outer surfaces of the plurality of rotating rods.

[0008] The technical effect of adopting the above-mentioned further solution is that the rotating rod and the limiting plate can be used to adjust whether the limiting plate and the counterweight slider are locked together, thereby adjusting whether the side of the filter plate is supported, thus facilitating the replacement of the filter plate.

[0009] In a preferred embodiment, the limiting plate is movably connected to the housing, and the counterweight slider on the other side is slidably embedded in the inner wall of the limiting plate.

[0010] The technical effect of adopting the above-mentioned further solution is that the sliding embedding of the counterweight slider and the limit plate ensures that there will be no jamming during normal up and down movement, thus improving the smoothness of the overall equipment.

[0011] In a preferred embodiment, a plurality of through grooves are provided on one side of the outer surface of the tray, and strip-shaped sealing valves are fixedly connected to the inner walls of the plurality of through grooves.

[0012] The technical effect of adopting the above-mentioned further solution is that the setting of the through groove and the strip sealing valve improves the sealing effect inside the filter.

[0013] In a preferred embodiment, the strip-shaped sealing valve is movably connected to the filter plate, and multiple plate replacement ports are provided at the bottom of the inner wall of the filter plate storage silo.

[0014] The technical effect of adopting the above-mentioned further solution is that the plate replacement port is compatible with the bottom through groove, thereby ensuring that the filter plate can be smoothly inserted into the inner wall of the groove plate from the replacement chamber, thereby improving the accuracy of the subsequent Y-shaped clamping column and multi-section rod clamping.

[0015] In a preferred embodiment, telescopic columns are fixedly installed on both sides of the inner wall of the silo, and a replacement chamber is fixedly connected to one end of the outer surface of each of the telescopic columns.

[0016] The technical advantage of adopting the above-mentioned further solution is that the replacement chamber is pushed by the telescopic column at the top, and the filter plate that is slidably embedded inside slides down through the outlet groove and the replacement port, which facilitates the replacement of the filter plate.

[0017] In a preferred embodiment, multiple filter plates are slidably embedded in the inner walls of the multiple replacement chambers, and an outlet groove is opened at the bottom of the outer surface of the multiple replacement chambers.

[0018] The technical advantages of adopting the above-mentioned further solution are: limit strips are set on both sides of the filter plates on the inner wall of the replacement chamber to prevent one side from losing its support and tilting after multiple filter plates are replaced. At the same time, the cooperation between the outlet groove and the replacement chamber allows the filter plates to be replaced one by one in sequence, ensuring the stability of filter plate replacement.

[0019] In a preferred embodiment, an air intake channel is provided on one side of the outer surface of the housing, and an air outlet channel is provided on the other side of the outer surface of the housing.

[0020] The technical effect of adopting the above-mentioned further solution is that the entrance and exit channels on both sides serve as the passageway for fly ash filtration.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0022] 1. In this invention, fly ash enters the casing through the intake channel, is filtered by the filter plate, and then discharged through the exhaust channel. The filter plate is secured to the bottom of a multi-section rod via a Y-shaped locking post. The Y-shaped locking post is attached to a round shaft at the bottom of the multi-section rod. The Y-shaped locking post is made of deformable soft rubber and rotates under the drive of an external power source, causing the multi-section rod to rotate. The multi-section rod is designed to be telescopic to prevent jamming during rotation. The rotation of the multi-section rod, through the Y-shaped locking post and the bottom of the multi-section rod, supports the filter plate, allowing it to move up and down. It supports, rather than pulls, the filter plate. In normal use, one filter plate is used for filtration, while the other is prepared for replacement. When replacement is needed after a period of use, the filter plate on one side is lowered, and the other side is raised for replacement. The filter plate has a strip-shaped sealing valve at the through groove position to improve the internal sealing effect. After replacement, the rotating rod on one side of the used filter plate rotates under the drive of an external power source, rotating the limiting plate to release its resistance to the counterweight slider. The counterweight slider has a counterweight block inside, which is heavier than the other side. After losing the side resistance, the filter plate will tilt towards the counterweight slider and fall under the action of gravity. The Y-shaped locking post will break the locking connection with the bottom round shaft of the multi-section rod and fall onto the surface of the soft rubber protective base. At this time, the replacement of the filter plate is completed. Compared with traditional filters, it is more convenient to replace the filter plate without manually turning the bolts. It solves the problem that the replacement of the filter plate in the existing technology still requires manual operation, which requires turning the handle to release the threaded rod and remove the filter plate for replacement, making the operation more troublesome.

[0023] 2. In this invention, when multiple replacements are required, the top telescopic column pushes the replacement chamber, causing the internally slidably embedded filter plate to slide down through the outlet groove and into the replacement port. Under the action of gravity, the Y-shaped locking post is locked onto the round shaft at the bottom of the multi-section rod. Limiting strips are provided on both sides of the filter plate on the inner wall of the replacement chamber to prevent one side from losing its support and tilting after multiple filter plates are replaced. The replacement port is adapted to the through groove at the bottom, thereby ensuring that the filter plate can be smoothly locked into the inner wall of the groove plate from the replacement chamber, thereby improving the accuracy of the subsequent locking of the Y-shaped locking post and the multi-section rod.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-7This invention provides a technical solution: a fly ash treatment filter, comprising: a housing 1, a support plate 2 fixedly installed inside the housing 1, a storage bin 3 fixedly installed on the top of the outer surface of the housing 1, multiple soft rubber protective bases 101 movably installed on the bottom of the inner wall of the housing 1, a partition 102 fixedly installed on the bottom of the inner wall of the housing 1, the soft rubber protective bases 101 being movably connected to the partition 102, a rotating shaft 4 movably installed on one side of the inner wall of the housing 1, multiple multi-section rods 5 fixedly sleeved on the outer surface of the rotating shaft 4, multiple slotted plates 7 fixedly embedded inside the support plate 2, a Y-shaped locking post 601 movably sleeved on one end of the outer surface of each of the multiple multi-section rods 5, a filter plate 6 fixedly installed on one end of the outer surface of each of the multiple Y-shaped locking posts 601, and a filter plate 6 fixedly installed on one side of the outer surface of each of the multiple filter plates 6. Multiple counterweight sliders 602 are fixedly installed, and limit blocks 603 are fixedly installed on the other side of the outer surface of multiple filter plates 6. The limit blocks 603 are slidably embedded in the inner wall of the trough plate 7. One side of the counterweight slider 602 is slidably embedded in the inner wall of the trough plate 7. After fly ash enters the machine casing 1 through the air intake channel 8, it is filtered by the filter plates 6 and then discharged through the air outlet channel 9. Here, the filter plates 6 are locked to the bottom end of the multi-section rod 5 by the Y-shaped locking post 601 at the bottom. The Y-shaped locking post 601 is locked on the round shaft at the bottom of the multi-section rod 5. The Y-shaped locking post 601 is made of deformable soft rubber material. It rotates under the drive of the rotating shaft 4 through the external power source, driving the multi-section rod 5 to rotate. The multi-section rod 5 is set as a telescopic rod to avoid rotation jamming. The rotation of the multi-section rod 5, via the Y-shaped locking post 601 and the bottom end of the multi-section rod 5, supports the filter plate 6, moving it up and down. This is supporting, not pulling. In normal use, one filter plate 6 is used for filtration, while the other is prepared for replacement. When replacement is needed after a period of use, the filter plate 6 on one side is lowered, and the other side is raised for replacement. During replacement, the filter plate 6 has a strip-shaped sealing valve 202 at the position where it passes through the through groove 201, improving the internal sealing effect. After replacement, the rotating rod 702 on one side of the used filter plate 6 rotates under the drive of an external power source, rotating the limiting plate 701 to release the resistance of the counterweight slider 602. The counterweight slider 602 has a counterweight block inside, which is heavier than the other side. After the side resistance is removed... The filter plate 6 will tilt towards one side of the counterweight slider 602 and fall over under the action of gravity. The Y-shaped locking post 601 will disengage from the locking connection with the bottom round shaft of the multi-section rod 5 and fall onto the surface of the soft rubber protective base 101. At this time, the replacement of the filter plate 6 is completed. Compared with traditional filters, it is more convenient to replace without manually tightening the bolts. In addition, when multiple replacements are required, the replacement chamber 303 is pushed by the telescopic column 302 at the top, and the filter plate 6 that is slidably embedded inside slides down through the outlet groove 304 and the replacement plate opening 301. Under the action of gravity, the Y-shaped locking post 601 is locked onto the bottom round shaft of the multi-section rod 5. Limiting strips are provided on both sides of the filter plate 6 on the inner wall of the replacement chamber 303 to prevent one side from losing support and tilting after multiple filter plates 6 are replaced.The filter plate replacement port 301 is adapted to the bottom through groove 201, thereby ensuring that the filter plate 6 can be smoothly inserted from the replacement chamber 303 into the inner wall of the groove plate 7, thus improving the accuracy of the subsequent engagement of the Y-shaped clamping post 601 and the multi-section rod 5.

[0035] Please see Figure 1-7 Multiple rotating rods 702 are movably installed on one side of the inner wall of the housing 1. Limiting plates 701 are fixedly installed on the outer surface of each rotating rod 702. The rotating rods 702 cooperate with the limiting plates 701 to adjust whether the limiting plates 701 and the counterweight slider 602 are locked together, thereby adjusting whether the side of the filter plate 6 is supported, thus facilitating the replacement of the filter plate 6.

[0036] Please see Figure 1-7 The limiting plate 701 is movably connected to the housing 1, and the counterweight slider 602 on the other side is slidably embedded in the inner wall of the limiting plate 701. The sliding embedding of the counterweight slider 602 and the limiting plate 701 ensures that there will be no jamming during normal up and down movement, thus improving the smoothness of the overall equipment.

[0037] Please see Figure 1-7 Multiple through grooves 201 are provided on one side of the outer surface of the tray 2. Each through groove 201 has a strip-shaped sealing valve 202 fixedly connected to its inner wall. The arrangement of the through grooves 201 and the strip-shaped sealing valve 202 improves the sealing effect inside the filter.

[0038] Please see Figure 1-7 The strip-shaped sealing valve 202 is movably connected to the filter plate 6. Multiple plate replacement ports 301 are opened at the bottom of the inner wall of the plate storage chamber 3. The plate replacement ports 301 are adapted to the through grooves 201 at the bottom, so as to ensure that the filter plate 6 can be smoothly inserted into the inner wall of the groove plate 7 from the replacement chamber 303, thereby improving the accuracy of the subsequent Y-shaped clamping column 601 and the multi-section rod 5.

[0039] Please see Figure 1-7 Both sides of the inner wall of the storage silo 3 are fixedly installed with telescopic columns 302. One end of the outer surface of each telescopic column 302 is fixedly connected to a replacement chamber 303. By pushing the replacement chamber 303 through the telescopic column 302 at the top, the filter plate 6 that is slidably embedded inside is slid down through the outlet groove 304 and the replacement port 301, which facilitates the replacement of the filter plate 6.

[0040] Please see Figure 1-7 Multiple filter plates 6 are slidably embedded in the inner walls of multiple replacement chambers 303. An outlet groove 304 is opened at the bottom of the outer surface of multiple replacement chambers 303. Limiting strips are provided on both sides of the filter plates 6 on the inner wall of the replacement chamber 303 to prevent one side from losing support and tilting after multiple filter plates 6 are replaced. At the same time, the cooperation between the outlet groove 304 and the replacement chamber 303 allows the filter plates 6 to be replaced one by one in sequence, ensuring the stability of the replacement of filter plates 6.

[0041] Please see Figure 1-7 An air inlet channel 8 is provided on one side of the outer surface of the casing 1, and an air outlet channel 9 is provided on the other side of the outer surface of the casing 1. The inlet and outlet channels on both sides are the paths through which fly ash is filtered and generated.

[0042] Working principle

[0043] Fly ash enters the casing 1 through the intake channel 8, is filtered by the filter plate 6, and then discharged through the exhaust channel 9. Here, the filter plate 6 is secured to the bottom of the multi-section rod 5 by a Y-shaped locking post 601 at the bottom. The Y-shaped locking post 601 is connected to the bottom of the multi-section rod 5 by clamping it onto the round shaft at the bottom of the multi-section rod 5. The Y-shaped locking post 601 is made of deformable soft rubber and rotates under the drive of the rotating shaft 4 via an external power source, thus rotating the multi-section rod 5. The multi-section rod 5 is designed as a telescopic rod to prevent jamming during rotation. The rotation of the multi-section rod 5 is achieved through the locking and connection of the Y-shaped locking post. The bottom of the locking post 601 and the multi-section rod 5 will support the filter plate 6 and move it up and down. This is supporting, not pulling. In normal use, one filter plate 6 is used for filtration, while the other is prepared for replacement. When replacement is needed after a period of use, the filter plate 6 on one side is lowered, and the other side is raised for replacement. During replacement, the filter plate 6 has a strip-shaped sealing valve 202 at the position where it passes through the through groove 201 to improve the internal sealing effect. After replacement, the rotating rod 702 on one side of the used filter plate 6 rotates under the drive of an external power source, rotating the limiting plate 701. The counterweight slider 602 is released from its support. The counterweight slider 602 contains a counterweight block, which is heavier than the other side. After losing its lateral support, the filter plate 6 tilts towards the counterweight slider 602 and falls over under gravity. The Y-shaped locking post 601 disconnects from the bottom shaft of the multi-section rod 5 and falls onto the surface of the soft rubber protective base 101. This completes the replacement of the filter plate 6. Compared to traditional filters, this method eliminates the need for manual bolt tightening, making replacement more convenient. Furthermore, when multiple replacements are required, the top telescopic column 30... 2. Push the replacement chamber 303 to slide the filter plate 6, which is slidably embedded inside, through the outlet groove 304 and the replacement port 301. Under the action of gravity, the Y-shaped locking post 601 is locked onto the round shaft at the bottom of the multi-section rod 5. The filter plate 6 on both sides of the inner wall of the replacement chamber 303 is provided with limit locking strips to prevent one side from losing support and tilting after multiple filter plates 6 are replaced. The replacement port 301 is adapted to the through groove 201 at the bottom to ensure that the filter plate 6 can be smoothly locked into the inner wall of the groove plate 7 from the replacement chamber 303, thereby improving the accuracy of the subsequent locking of the Y-shaped locking post 601 and the multi-section rod 5.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
