Description

Technical Field

[0001] This application belongs to the field of high temperature and high pressure filtration, specifically a high temperature and high pressure inclined plate self-cleaning filter device. Background Technology

[0002] In industrial fields such as thermal power generation, it is often necessary to filter high-temperature and high-pressure fluids to remove impurities and ensure the smooth operation of subsequent processes. For example, when power plants take intermediate water samples, some filtration equipment is required to filter high-temperature and high-pressure fluids.

[0003] Existing filtration devices have the following problems when used in high temperature and high pressure environments: as filtration proceeds, impurities will continuously adhere to the surface of the filter medium, resulting in increased filtration resistance and reduced filtration efficiency. Moreover, most existing traditional filtration devices do not have good self-cleaning functions, requiring frequent manual disassembly and cleaning, which increases labor intensity and has low efficiency. Therefore, there is an urgent need to design a filtration device that can adapt to high temperature and high pressure environments and has a self-cleaning function. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies by using multiple inclined filter plates with progressively sieved sections inside the casing to filter water samples step by step from bottom to top. This allows impurities to fall off automatically under the guidance of gravity and the filter plates, preventing accumulation. This solves the problem that most existing traditional filtration devices do not have good self-cleaning functions, require frequent manual disassembly and cleaning, increase labor intensity, and have low efficiency.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] A high-temperature, high-pressure inclined plate self-cleaning filter device includes a housing, a filter mechanism disposed in the middle of the housing, a discharge pipe fixedly connected to the upper front side of the housing, an inlet pipe fixedly connected to the lower front side of the housing, and a discharge pipe fixedly connected to the lower part of the housing. The filter mechanism includes two mounting plates, which are movably connected to the inner wall of the housing by bolts. Multiple filter plates are movably connected between the two mounting plates. The mesh size of the multiple filter plates increases from bottom to top, and the multiple filter plates are all inclined with the left side higher than the right side.

[0007] Preferably, a frame is fixedly connected to the side of each of the two mounting plates that are close to each other.

[0008] Preferably, a slot is provided in the middle of the top surface of the inner wall of the frame.

[0009] Preferably, mounting rods are fixedly connected to both the left and right sides of the filter plate, and the mounting rods are movably connected to the frame.

[0010] Preferably, the mounting rod has a mounting groove in the middle, a spring is slidably connected to the middle of the mounting groove, the spring engages with the slot, and a retaining bead is fixedly connected between the spring and the mounting groove.

[0011] Preferably, except for the filter plate located at the top, all other filter plates have discharge ports on their right sides.

[0012] Preferably, mounting brackets are fixedly connected to the left and right sides of the inner wall of the outer casing, and the two mounting brackets are symmetrically arranged. A slot can be formed between the mounting bracket and the inner wall of the outer casing, and the lower part of the mounting plate is inserted into the slot.

[0013] Preferably, a top plate is bolted to the top of the housing.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] 1. This application uses multiple inclined filter plates with progressively sieved surfaces inside the casing to filter water samples from bottom to top. Impurities can fall off automatically under the guidance of gravity and the filter plates, preventing accumulation and clogging. The multiple filter plates can also be automatically rinsed by reverse water intake, eliminating the need for manual cleaning and making it more practical.

[0016] 2. This application sets a frame on the mounting plate and sets mounting rods on both sides of the filter plate. Through the cooperation between the mounting plate and the mounting frame, the disassembly and assembly of the filter plate are made more convenient and quick. At the same time, through the cooperation between the locking beads and the locking groove, the filter plate can be quickly positioned during installation, which can effectively improve its practicality.

[0022] Reference Figures 1-4 A high-temperature and high-pressure inclined plate self-cleaning filter device includes a housing 1, a filter mechanism 2 is arranged in the middle of the housing 1, brackets 3 are fixedly connected to the left and right sides of the housing 1, a discharge pipe 13 is fixedly connected to the upper front side of the housing 1, an inlet pipe 14 is fixedly connected to the lower front side of the housing 1, and a discharge pipe 15 is fixedly connected to the lower part of the housing 1. The filter mechanism 2 includes two mounting plates 21, which are movably connected to the inner wall of the housing 1 by bolts. Multiple filter plates 23 are movably connected between the two mounting plates 21. The mesh size of the multiple filter plates 23 increases from bottom to top, and the multiple filter plates 23 are all inclined with the left side higher than the right side.

[0023] In this embodiment, during use, the water to be sampled from the power plant enters the outer casing 1 through the inlet pipe 14. As the water volume increases, the liquid gradually spreads upward. As the water flow rises, the water body passes through multiple filter plates 23 sequentially from bottom to top. Impurities in the water are filtered step by step. Since the water body is filtered from bottom to top, and the filter plates 23 are inclined, the impurities will fall to the lower part of the outer casing 1 under the guidance of gravity and the filter plates 23, thereby reducing the risk of impurity accumulation and clogging of the filter plates 23. The filtered water body is discharged through the outlet pipe 13 for sampling. At the same time, when sampling filtration is not performed, clean water can be supplied from the outlet pipe 13 into the outer casing 1 to backwash the multiple filter plates 23, thereby realizing automatic cleaning of the filter plates 23. After cleaning, impurities and sewage can be discharged through the discharge pipe 15. Valves for controlling the entry and exit of liquid are provided in the inlet pipe 14, the outlet pipe 13, and the discharge pipe 15.

[0026] As a preferred embodiment, mounting rods 231 are fixedly connected to both the left and right sides of the filter plate 23. The mounting rods 231 are movably connected to the frame 211 and are used to facilitate the connection between the filter plate 23 and the mounting plate 21.

[0027] As a preferred embodiment, the mounting rod 231 has a mounting groove 232 in the middle, which is used to connect components such as the retaining bead 234 and the spring 233. The spring 233 is slidably connected in the middle of the mounting groove 232, which is used to connect the retaining bead 234 and the retaining groove 212. The spring 233 is engaged with the retaining groove 212, and the retaining bead 234 is fixedly connected to the spring 233 and the mounting groove 232 together, and it cannot be separated from the mounting groove 232.

[0028] As a preferred method, except for the filter plate 23 located at the top, the filter plate 23 and the filter plate 23 are provided with discharge ports 235 on the right side to help impurities fall to the lower part of the outer shell 1.

[0029] As a preferred embodiment, mounting brackets 16 are fixedly connected to the left and right sides of the inner wall of the outer casing 1. These brackets are used to facilitate the quick positioning and installation of the filter mechanism 2. The two mounting brackets 16 are symmetrically arranged, and a slot can be formed between the mounting bracket 16 and the inner wall of the outer casing 1. The length and width of the slot are adapted to the mounting plate 21. The lower part of the mounting plate 21 is inserted into the slot to facilitate the initial positioning of the mounting plate 21.

[0030] As a preferred embodiment, a top plate 11 is bolted to the top of the housing 1, which is used to facilitate the assembly and disassembly of the filter mechanism 2 inside the housing 1.
