Description

Technical Field

[0001] This utility model belongs to the field of filter technology, and in particular relates to a novel candle wick backwash filter. Background Technology

[0002] Backwash filters are a direct product of modern industrial automation and the demand for efficient water resource utilization. Through an innovative "online backwashing" mechanism, they revolutionarily solve the problem of traditional filters requiring shutdown for cleaning. This provides crucial basic equipment for numerous industries requiring continuous, stable, and efficient filtration. Their development reflects the trend of industrial equipment moving towards intelligent and unmanned operation, and is an important technical means to improve production efficiency, reduce operating costs, and ensure the safe and stable operation of systems. In a backwash filter, the fluid to be filtered enters the filter through the inlet, flows through the filter elements (filter screen, filter cartridge, filter rod, filter disc, or filter bed), and impurities are trapped on the surface or inside of the filter elements. Clean fluid flows out through the outlet. Due to their automation and high efficiency, backwash filters are widely used in applications requiring continuous operation and stable filtration results.

[0003] However, existing backwash filters, during backwashing, cannot control the swirling of the liquid within the filter, thus failing to effectively clean stubborn dirt from the filter element surface. Therefore, we provide a novel candle-wick type backwash filter to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of candle wick backwash filter, which improves the comprehensiveness and efficiency of cleaning the inside of the cylinder by using backwash pipes, curved pipes and turbulent air pipes in combination.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a novel candle wick type backwash filter, including a cylinder; a cap is provided on the upper end face of the cylinder, and multiple sets of evenly distributed powder sintered filter elements are arranged inside the cylinder. A perforated plate is provided between the cylinder and the cap above the powder sintered filter elements. The upper port of the powder sintered filter element passes through the port of the perforated plate. The end of the powder sintered filter element above the perforated plate is screwed to the perforated plate by a nut. A curved pipe connected to the inside of the cylinder is fixed on the outer side wall below the perforated plate. The curved port of the curved pipe inside the cylinder is oriented upward. A vent pipe, a liquid level pipe and a backwash pipe are fixed on the upper side of the cap in a triangular arrangement. A turbulence air pipe is fixed on the outer side wall of the cylinder.

[0007] The present invention is further provided that two sets of lifting lugs are fixed on the upper surface of the end cap in a symmetrical arrangement.

[0008] The present invention is further configured such that flanges are fixed on the opposite end faces of the end cap and the cylinder, and the two sets of flanges are connected by bolts.

[0009] The present invention is further configured such that a drain pipe communicating with the interior is fixed on the outer side wall of the end cap, and a liquid inlet pipe communicating with the interior is fixed on the outer side wall of the cylinder.

[0010] The present invention is further configured such that the turbulence-inducing air pipe and the liquid inlet pipe are arranged symmetrically in a ring along the surface of the cylinder, and the turbulence-inducing air pipe and the liquid outlet pipe are arranged at the same vertical position.

[0011] The present invention is further configured such that a turbid liquid pipe communicating with the interior is fixed to the lower surface wall of the cylinder, and multiple sets of leg-type supports are fixed to the lower part of the surface wall of the cylinder in a ring-shaped arrangement.

[0012] The present invention is further configured such that a positioning ring plate is provided inside the cylinder located directly below the powder sintered filter element, and a nut is threadedly connected to the end of the lower shaft of the powder sintered filter element that passes through the positioning ring plate.

[0013] This utility model has the following beneficial effects:

[0014] Open the backflushing pipe and the bend pipe. The backflushing pipe fills the inside of the cylinder with nitrogen. Under the pressure of the nitrogen, the liquid above the bend pipe will be forced out from the bend pipe port inside the cylinder. When no liquid flows out of the bend pipe, the liquid pressure operation is complete. At the same time, nitrogen continues to be filled. During backflushing, open the turbulence gas pipe to introduce turbulence gas into the inside of the cylinder, causing the liquid inside the cylinder to rotate, achieving a better cleaning effect, improving the comprehensiveness of cleaning and increasing cleaning efficiency.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] Please see Figures 1 to 3 This utility model is a novel candle wick backwash filter. By using the backwash pipe 1010, the curved pipe 102 and the turbulent air pipe 104 in combination, the cleaning of the inside of the cylinder 1 is improved in terms of comprehensiveness and efficiency.

[0023] Specifically, the cylinder 1 has a cap 5 on its upper end face. Multiple sets of evenly distributed powder sintered filter elements 3 are installed inside the cylinder 1. A perforated plate 4 is positioned between the cylinder 1 and the cap 5 above the powder sintered filter elements 3. The upper end of the powder sintered filter element 3 passes through the port of the perforated plate 4. The end of the powder sintered filter element 3 above the perforated plate 4 is screwed to the perforated plate 4 via a nut. A curved pipe 102, communicating with the interior, is fixed to the outer wall of the cylinder 1 below the perforated plate 4. The curved end of the curved pipe 102 inside the cylinder 1 faces upwards. A triangularly arranged vent pipe 106 and a liquid level pipe 10 are fixed to the upper surface of the cap 5. 9 and backflushing pipe 1010, two sets of symmetrically arranged lifting lugs 108 are fixed on the upper surface of the end cap 5, a drain pipe 107 connected to the inside is fixed on the surface wall of the end cap 5, a liquid inlet pipe 101 connected to the inside is fixed on the surface wall of the cylinder 1, a turbulence vent pipe 104 is fixed on the surface wall of the cylinder 1, the turbulence vent pipe 104 and the liquid inlet pipe 101 are arranged symmetrically in a ring along the surface of the cylinder 1, the turbulence vent pipe 104 and the drain pipe 107 are arranged in the same vertical position, a turbid liquid pipe 103 connected to the inside is fixed on the lower surface wall of the cylinder 1, and multiple sets of evenly distributed leg supports 2 in a ring are fixed on the lower part of the surface wall of the cylinder 1.

[0024] The operation process of this embodiment is as follows: the liquid material enters from the inside of the liquid inlet pipe 101, the inside of the cylinder 1 is gradually filled with liquid, and it is filtered from the outside of the powder sintered filter element 3 to the inside. After the powder sintered filter element 3 filters the liquid, the clear liquid in it will enter the end cap 5, thereby opening the drain pipe 107, so that the clear liquid in the end cap 5 will be discharged from the inside of the drain pipe 107.

[0025] When pressurizing the remaining liquid inside the cylinder 1, open the backflushing pipe 1010 and the bend pipe 102, and close the drain pipe 107, inlet pipe 101, turbulence pipe 104, vent pipe 106 and liquid level pipe 109. Nitrogen gas is introduced into the cylinder 1 through the backflushing pipe 1010. Under the pressure of nitrogen gas, the liquid above the bend pipe 102 will be forced out from the port of the bend pipe 102 inside the cylinder 1. When no liquid flows out from the inside of the bend pipe 102, the pressurization work is completed.

[0026] When backflushing the inside of the powder sintered filter element 3, nitrogen gas is continuously introduced into the inside of the cylinder 1. The gas flows downward from the center of the powder sintered filter element 3, passes through the bottom of the powder sintered filter element 3 and then diffuses upward, and diffuses outward from the inside of the powder sintered filter element 3, thereby backflushing the filter element. During backflushing, the turbulence gas pipe 104 is opened to introduce turbulence gas into the inside of the cylinder 1, causing the liquid inside the cylinder 1 to rotate, achieving a better cleaning effect. After backflushing, the inside of the cylinder 1 needs to be drained. At this time, the venting pipe 106 and the turbid liquid pipe 103 are opened to release the gas inside the cylinder 1 and discharge the turbid liquid inside the cylinder 1. Example 2

[0027] Please see Figure 2 Based on Example 1, the position of the powder sintered filter element 3 is kept stable by using the positioning ring plate 301 and the powder sintered filter element 3 together.

[0028] Specifically, flanges 105 are fixed to the opposite end faces of the end cap 5 and the cylinder 1. The two sets of flanges 105 are connected by bolts. A positioning ring plate 301 is provided inside the cylinder 1 located directly below the powder sintered filter element 3. A nut is threaded to the end of the lower shaft of the powder sintered filter element 3 that passes through the positioning ring plate 301.

[0029] The operation process of this embodiment is as follows: multiple sets of powder sintered filter elements 3 are positioned by the positioning ring plate 301, and the powder sintered filter elements 3 and the positioning ring plate 301 are assembled together by nuts. Thus, the positioning ring plate 301 positions the powder sintered filter elements 3, ensuring the stable assembly between multiple sets of powder sintered filter elements 3, and preventing the powder sintered filter elements 3 from shaking easily.
