Description

Technical Field

[0001] This utility model belongs to the field of boiler slag removal technology, and in particular relates to a filter screen for boiler slag removal that is easy to install. Background Technology

[0002] Boiler slag removal refers to the process of removing ash and sediments remaining inside the boiler after combustion through physical or chemical methods during boiler operation. These residues mainly come from non-combustible components in the fuel, solid residues formed by incomplete combustion during the combustion process, such as coal gangue and slag. If not cleaned in time, these residues will reduce the boiler's thermal efficiency, increase energy consumption, and may lead to equipment damage or even safety accidents.

[0003] The existing boiler ash removal systems lack a filter screen that can be installed quickly. The problem with the aforementioned technology is that there is a lack of a filter screen device in the existing boiler ash removal system that can be quickly installed and removed. Traditional filter screen fixing methods are usually quite complicated, requiring a lot of time and manpower for installation and removal. This not only reduces work efficiency but also increases maintenance costs. Since the filter screen needs to be cleaned or replaced frequently to ensure the efficient operation of the boiler system, this inconvenience directly affects the efficiency of the entire ash removal process. Specifically, the installation of traditional filter screens often involves multiple steps, such as manual adjustment and tightening screws, which are cumbersome and time-consuming. In addition, the complex installation process also increases the technical requirements of the operators and the possibility of errors. If the filter screen is not installed properly, it may lead to incomplete ash removal or even cause equipment failure or safety accidents. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides an easy-to-install filter screen for boiler slag removal that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a filter screen for boiler slag removal that is easy to install includes a filter screen, a fixing plate and a conveying pipe. The two sides of the filter screen are in contact with the surfaces of the two fixing plates. The lower end of the fixing plate is fixedly connected to the upper surface of the conveying pipe. An installation mechanism is provided inside the fixing plate, and an auxiliary mechanism is provided at the front end of the fixing plate.

[0006] The mounting mechanism is used to fix the filter screen;

[0007] The auxiliary mechanism is used to fix the installation mechanism.

[0008] To improve work efficiency, preferably, the installation mechanism includes a connecting rod, top wheels, fixing blocks, a support plate, and an elastic block. The surface of the connecting rod is fixedly connected to the inner walls of the two top wheels, the surface of the top wheels is in sliding contact with the rear surface of the fixing blocks, the rear end surfaces of the two fixing blocks are fixedly connected to the side surfaces of the support plate, and the middle surface of the support plate is fixedly connected to the front surface of the elastic block. When the connecting rod is rotated, it can effectively push the fixing blocks into the mounting slots on both sides of the filter screen, simplifying the filter screen installation process.

[0009] To improve operational accuracy, the auxiliary mechanism preferably includes a mounting block, a ratchet, a mating wheel, a spring, and a retaining ring. The inner wall of the mounting block is fixedly connected to the surface of the ratchet, the teeth of the ratchet slide in contact with the teeth of the mating wheel, the lower end of the mating wheel is fixedly connected to the upper end of the spring, and the lower end of the spring is fixedly connected to the upper surface of the retaining ring. The mating wheel can slide smoothly on the surface of the ratchet and achieve unidirectional rotation through its tooth structure, ensuring that the connecting rod can only rotate in one direction and preventing accidental loosening or reverse rotation.

[0010] To improve operational stability, preferably, a telescopic rod is provided on the surface of the fixed ring, and the lower end of the telescopic rod is fixedly connected to the surface of the fixed ring. The filter screen has mounting grooves on both sides, and the telescopic rod can extend and retract under the guidance of the fixed ring. The telescopic rod not only provides stable support for the mating wheel, but also allows its length to be flexibly adjusted according to operational needs, ensuring that the mating wheel always maintains the best contact state with the ratchet.

[0011] To improve the adaptability of the device, preferably, the surface of the connecting rod is slidably connected to the inner wall of the fixing plate, the surface of the fixing block is slidably connected to the inner wall of the fixing plate through a sliding groove, the surface of the support plate is slidably connected to the inner wall of the fixing plate, and the rear surface of the elastic block is fixedly connected to the inner wall of the fixing plate. The elastic block provides the necessary elastic restoring force for the entire device, and can automatically pop the fixing block out of the mounting groove, simplifying the disassembly process of the filter screen.

[0012] To improve the reliability of the device, preferably, the surface of the mounting block is fixedly connected to the front surface of the fixing plate, the inner wall of the fixing ring is fixedly connected to the surface of the connecting rod, and the surface of the mating wheel is slidably connected to the inner wall of the fixing ring through a sliding groove. The mating wheel can slide smoothly inside the fixing ring and adjust its position according to actual needs. The sliding groove provides a precise guiding function to ensure that the mating wheel always maintains the best contact state with the ratchet, thus ensuring the effective operation of unidirectional rotation.

[0013] To improve the service life of the device, preferably, the upper end of the telescopic rod is fixedly connected to the lower end of the mating wheel, the inner wall of the mounting groove is in sliding contact with the surface of the fixing block, and the fixing block can move inside the mounting groove, thereby realizing the quick installation and removal of the filter screen. The mounting groove provides a precise guiding function to prevent the fixing block from shifting or getting stuck during the movement.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model incorporates an installation mechanism, an auxiliary mechanism, a connecting rod, a top wheel, a fixing block, a support plate, a ratchet, a mating wheel, a spring, and a fixing ring. The installation mechanism secures the filter screen, while the auxiliary mechanism secures the installation mechanism. Rotating the connecting rod effectively pushes the fixing block into the installation slots on both sides of the filter screen, simplifying the installation process. The mating wheel slides smoothly on the ratchet surface and achieves unidirectional rotation through its toothed structure, ensuring the connecting rod can only rotate in one direction and preventing accidental loosening or reverse rotation. This invention solves the problem of the lack of a quick-installation and disassembly filter screen device in existing boiler slag removal systems. Traditional filter screen installation is complex, time-consuming, and labor-intensive, affecting work efficiency and maintenance costs. Frequent cleaning or replacement of the filter screen is crucial for boiler system efficiency, but traditional installation methods are cumbersome, technically demanding, and prone to errors, potentially leading to incomplete slag removal or equipment malfunction.

The two rear surfaces of the two fixing blocks 103 are in contact with the inner wall of the top wheel 102. The end surface is fixedly connected to both sides of the support plate 104, and the middle surface of the support plate 104 is fixedly connected to the front surface of the elastic block 105. When the connecting rod 101 is rotated, it can effectively push the fixing block 103 into the mounting grooves 4 on both sides of the filter screen 5, simplifying the installation process of the filter screen 5. The auxiliary mechanism 2 includes a mounting block 201, a ratchet 202, a mating wheel 203, a spring 204, and a fixing ring 205.

This enables the quick installation and removal of the filter screen 5. The mounting groove 4 provides precise guidance, preventing the fixing block 103 from shifting or jamming during movement.

[0024] The working principle of this utility model:

[0025] In the boiler residue treatment process, firstly, the operator needs to place the filter screen 5 between the pre-positioned fixing plates 6, ensuring its accurate positioning. Then, by rotating the connecting rod 101, the two top wheels 102 on the connecting rod 101 push the fixing blocks 103, causing them to insert into the mounting grooves 4 on both sides of the filter screen 5. During this process, the rotation of the connecting rod 101 not only moves the fixing blocks 103 but also drives the mating wheel 203 to slide on the toothed surface of the ratchet 202 via the fixing ring 205 on its surface. Under the action of the spring 204 and the telescopic rod 3, the mating wheel 203 can stably slide on the surface of the ratchet 202 and engage with the toothed structure on the surface of the ratchet 202, thus achieving unidirectional rotation of the connecting rod 101. This unidirectional rotation mechanism ensures close contact between the fixing blocks 103 and the mounting grooves 4, thereby achieving rapid cleaning of the filter screen 5. Once the filter screen 5 is fixed, the operator can begin boiler slag removal through it. The function of the filter screen 5 is to intercept residue and ensure the cleanliness of the boiler interior, thereby improving the boiler's operating efficiency. However, as the usage time increases, residue will gradually accumulate on the filter screen 5, affecting its filtration effect. Therefore, it is necessary to clean or replace the filter screen 5 regularly. When it is necessary to clean or replace the filter screen 5, the operator only needs to pull the connecting rod 101 out a certain distance, so that the mating wheel 203 disengages from the surface of the ratchet 202. This operation removes the restriction of unidirectional rotation, allowing the connecting rod 101 to rotate in the opposite direction. During the reverse rotation, the support plate 104 on the fixing block 103 will be pulled out of the mounting groove 4 by the elastic block 105. In this way, the filter screen 5 can be easily removed from between the fixing plates 6, completing the disassembly work.
