Description

Technical Field

[0001] This utility model relates to the field of filter tank technology, and in particular to a filter tank structure for a water purification station. Background Technology

[0002] In water purification systems, the filter tank is one of the core treatment units. It mainly uses its internal filter cartridges (or filter elements) to physically filter raw water, trapping suspended solids, particulate impurities, and other contaminants to ensure that the effluent water quality meets standards. During long-term operation, impurities gradually accumulate on the surface and inside the filter cartridges, leading to increased filtration resistance, decreased flow rate, and even affecting the effluent water quality and water supply stability. Regular cleaning and maintenance of the filter cartridges are necessary measures to ensure the long-term efficient operation of the filtration system.

[0003] Currently, one of the common cleaning methods is backwashing technology. When backwashing, it is usually necessary to stop the water intake of the filter tank or switch to offline mode, interrupting the normal filtration process. During the cleaning, the water supply filtration task cannot be completed simultaneously. In other words, in the existing technology, the cleaning and filtration functions of the filter tank often cannot be carried out at the same time, making it difficult to achieve online self-cleaning under uninterrupted operation, which restricts the overall efficiency and automation level of the filtration system. Utility Model Content

[0004] In view of the problem that the cleaning and filtration functions of existing filter tanks often cannot be performed simultaneously, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a filter tank structure for a water purification station, which aims to achieve the self-cleaning function of the filter tank during continuous operation.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a filter tank structure for a water purification station, including a tank body with an inlet at the bottom, a tank cover fixed to the open top of the tank body by bolts, a drain pipe welded to the outlet on one side of the tank body, a sewage pipe welded to the sewage outlet on the other side of the tank body, and a ring-shaped brush disc detachably installed inside the tank body. A cleaning component is installed on the top of the can lid, and the movable end of the cleaning component passes through the can lid and enters the interior of the filter cylinder. Several annular brush discs are installed at equal intervals on the movable end of the cleaning component inside the filter cylinder.

[0007] As an improved technical solution, the cleaning assembly includes a longitudinally sliding lifting sleeve and a second servo motor for driving the lifting sleeve to rise and fall. The second servo motor is longitudinally limited and slidably installed inside the lifting sleeve and near one end of the second servo motor. The top of the can lid is equipped with a first servo motor for driving the rotating rod to rotate via a bracket.

[0008] As an improved technical solution, limit grooves are provided on both sides of the inside of the lifting sleeve, and limit grooves are welded on both sides of the outer wall of the rotating rod, and the limit strip slides inside the limit groove.

[0009] As an improved technical solution, the lifting sleeve has multiple meshing discs installed longitudinally at equal intervals at one end near the first servo motor, and a meshing cavity is formed between two adjacent meshing discs. The output shaft of the second servo motor is equipped with gears that mesh with the meshing discs.

[0010] As an improved technical solution, a ring frame is welded into the inner hole of the annular brush disc, and the ring frame is sleeved on the outer wall of the lifting sleeve through a circular hole at its center.

[0011] As an improved technical solution, a first fixing ring is welded inside the tank and between the drain pipe and the sewage pipe. An annular convex edge is welded to one end of the filter screen cylinder near the first fixing ring. A ring of smooth screws is fixed at the center of the first fixing ring, and a fixing hole for the smooth screws to pass through is opened at the top of the annular convex edge.

[0012] As an improved technical solution, a second fixing ring is welded inside the tank and near the drain end. The top of the second fixing ring has an annular cavity that matches the wall thickness of the filter screen cylinder, and a sealing ring is provided inside the annular cavity.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, the top end of the filter screen cylinder is snapped into the smooth rod screw, and the bottom end of the filter screen cylinder is snapped into the inside of the annular cavity. The snapping and limiting are performed from both ends of the filter screen cylinder at the same time to ensure that the filter screen cylinder is in a straight and firm state, thereby effectively ensuring the filtration stability of the filter screen cylinder. At the same time, the bottom end of the filter screen cylinder will also squeeze the sealing ring to improve the sealing performance.

[0014] 2. This utility model uses an annular brush disc to clean the inner wall of the filter cylinder. The annular brush disc is driven to rotate and rise and fall inside the tank by the cleaning component, which effectively expands the cleaning area of ​​the annular brush disc, thereby improving the comprehensiveness and uniformity of cleaning the filter cylinder. Furthermore, the filtration operation does not need to be interrupted during the self-cleaning process, so filtration and cleaning can be carried out simultaneously, thereby improving water supply efficiency.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Example 1 Reference Figures 1-4 This is the first embodiment of the present utility model, which provides a filter tank structure for a water purification station. This filter tank structure for a water purification station includes a tank body 1 with a water inlet at the bottom, a tank cover 2 fixed to the open end of the top of the tank body 1 by bolts, a drain pipe 7 welded to the water outlet on one side of the tank body 1, a drain pipe 8 welded to the sewage outlet on the other side of the tank body 1, a control valve installed at the water outlet end of the drain pipe 8, and an annular brush disc 5 detachably installed inside the tank body 1. A cleaning component 3 is installed on the top of the can lid 2, and the movable end of the cleaning component 3 passes through the can lid 2 and enters the interior of the filter cylinder 4. Several annular brush discs 5 are installed at equal intervals on the movable end of the cleaning component 3 inside the filter cylinder 4, and the bristles on the outer wall of the annular brush discs 5 abut against the inner wall of the filter cylinder 4.

[0022] The annular brush disc 5 cleans the inner wall of the filter cylinder 4, and the cleaning component 3 drives the annular brush disc 5 to rotate and rise inside the tank 1, effectively expanding the cleaning area of ​​the annular brush disc 5, thereby improving the comprehensiveness and uniformity of cleaning the filter cylinder 4. Furthermore, the self-cleaning process does not require interruption of the filtration operation, realizing simultaneous filtration and cleaning, and improving water supply efficiency.

[0023] The cleaning assembly 3 includes a longitudinally sliding lifting sleeve 31 and a second servo motor 38 for driving the lifting sleeve 31 to rise and fall. The second servo motor 38 is mounted on the top of the can lid 2 via a pad. The bottom end of the lifting sleeve 31 is located inside the filter cylinder 4, and the top end of the lifting sleeve 31 is located above the can lid 2. The second servo motor 38 is longitudinally limited and slidably mounted inside the lifting sleeve 31 and near one end of the second servo motor 38. The top of the can lid 2 is mounted with a first servo motor 36 for driving the rotating rod 35 to rotate via a bracket 37, and the output shaft of the first servo motor 36 passes through the bracket 37 and is fixed at the center of the top of the rotating rod 35.

[0024] Limiting grooves 33 are provided on both sides inside the lifting sleeve 31, and limiting grooves 33 are welded on both sides of the outer wall of the rotating rod 35. The limiting strip 34 slides inside the limiting groove 33. The bristles on the annular brush disk 5 clean the inner wall of the filter screen cylinder 4 and scrape off the impurities adhering to the inner wall. The dynamic rotation cleaning not only ensures the comprehensiveness of cleaning, but also improves the dust removal effect.

[0025] The lifting sleeve 31 has multiple meshing discs 32 installed longitudinally at equal intervals at one end near the first servo motor 36. A meshing cavity is formed between two adjacent meshing discs 32. The output shaft of the second servo motor 38 is equipped with a gear 39 that meshes with the meshing discs 32.

[0026] A ring frame 6 is welded into the inner hole of the annular brush disc 5, and the ring frame 6 is sleeved on the outer wall of the lifting sleeve 31 through a round hole set at its center.

[0027] Inside the tank body 1, between the drain pipe 7 and the sewage pipe 8, a first fixing ring disc 41 is welded. The filter screen cylinder 4 passes through the central hole of the first fixing ring disc 41. An annular protrusion 42 is welded to one end of the filter screen cylinder 4 near the first fixing ring disc 41. A ring of smooth screws 43 is fixed at the center of the first fixing ring disc 41. The top of the annular protrusion 42 is provided with a fixing hole 44 for the smooth screws 43 to pass through. The number of smooth screws 43 and fixing holes 44 is the same. A hexagonal nut is threaded onto the threaded end of the smooth screw 43. The hexagonal nut is pressed against the top of the annular protrusion 42. The smooth screws 43 and fixing holes 44 are made of stainless steel and have been treated with rust prevention.

[0028] A second fixing ring 45 is welded inside the tank body 1 near the drain end. The top of the second fixing ring 45 has an annular cavity that matches the wall thickness of the filter cylinder 4, and the bottom end of the filter cylinder 4 is located inside the annular cavity. A sealing ring 46 is provided inside the annular cavity. The top end of the filter cylinder 4 is engaged with the smooth rod screw 43, and the bottom end of the filter cylinder 4 is engaged and limited from both ends of the filter cylinder 4, ensuring that the filter cylinder 4 is in a straight and firm state, thereby effectively ensuring the filtration stability of the filter cylinder 4. At the same time, the bottom end of the filter cylinder 4 also squeezes the sealing ring 46 to improve the sealing performance.

[0029] The working principle of this utility model is as follows: The filter screen cylinder 4 is installed in the following process: the filter screen cylinder 4 passes through the inside of the first fixing ring disk 41. Normally, the bottom end of the filter screen cylinder 4 is inserted into the annular cavity at the top of the second fixing ring disk 45, and the smooth rod screw 43 passes through the inside of the fixing hole 44 and is fixed by installing a hexagonal nut. Water enters the interior of tank 1 through the inlet end of tank 1, and then is filtered directly through filter screen 4 before being discharged from drain pipe 7. The filtered impurities flow inside filter screen 4 and the upper side of the interior of tank 1. When cleaning is required during filtration, the first servo motor 36 drives the rotating rod 35 to rotate. With the limit bar 34 and the limit slide groove 33 engaged, the lifting sleeve 31 rotates synchronously with the rotating rod 35, thereby driving the annular brush disk 5 to rotate, so that the bristles on the annular brush disk 5 clean the inner wall surface of the filter cylinder 4. The second servo motor 38 drives the gear 39 to rotate counterclockwise. Under the meshing transmission action of the gear 39 and the meshing disc 32, the lifting sleeve 31 will be driven to move upward, thereby realizing the synchronous upward adjustment of the corresponding height of multiple annular brush discs 5, expanding the cleaning area of ​​the filter cylinder 4. Since the rotating rod 35 slides longitudinally within the lifting sleeve 31, the lifting and lowering of the lifting sleeve 31 will not affect the normal rotation of the lifting sleeve 31 driven by the rotating rod 35. Simply open the drain pipe 8 to discharge the impurities.
