Description

Technical Field

[0001] The utility model relates to the technical field of laminated filters, in particular to a manually controlled laminated filter. Background Art

[0002] The working principle of the laminated filter is mainly based on its unique filter unit structure. This filter is composed of a group of annular reinforced plastic filter discs with grooves or edges. These filter discs are tightly stacked in the unit to form a filter unit that is loose on the outside and tight on the inside. When water flows through these filter discs, the impurity particles in the water are trapped at the intersections formed by the grooves and edges on the filter discs, thereby achieving filtration.

[0003] In the filtering state, water is filtered from the outside of the filter element through the disc. The disc is tightly pressed together by the spring particles and liquid particles. Impurity particles are trapped at the intersection of the discs, and the filtered water flows out of the filter body. When a certain pressure difference or time is reached, the system automatically enters the backwash state. The traditional backwash component uses a grooved tee and a clamped grooved butterfly valve to achieve the backwash function. This component structure requires two manual butterfly valves to be opened and closed for each unit, and this butterfly valve often has high pressure and is not closed tightly, such as Figure 6-8 As shown, the use requirements of the existing laminated filters cannot be met. Utility Model Content

[0004] The utility model aims to provide a manually controlled laminated filter, which adopts a manual three-way valve to replace the three-way pipeline of traditional design, and solves the sealing problem of traditional butterfly valve fasteners.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a manually controlled laminated filter, comprising a laminated filter unit, a water inlet pipe, a sewage pipe and a water outlet pipe, wherein the laminated filter unit is located above the water outlet pipe, the laminated filter unit is connected to the sewage pipe and the water inlet pipe via a manual three-way valve, the manual three-way valve is connected to the pipeline interface via a grooved pipe joint, and the sewage outlet and the water outlet are connected or closed by moving the valve core of the manual three-way valve.

[0006] Preferably, the bottom of the water inlet pipe and the water outlet pipe are both provided with a metal foot cup bracket for supporting the entire laminated filter.

[0007] Preferably, an axial pressure gauge and an exhaust valve are installed on the water inlet pipe at one end away from the water inlet.

[0008] Preferably, a radial pressure gauge is installed on the water outlet pipe at one end away from the water outlet.

[0009] Preferably, a plug is installed on the water outlet pipe at one end away from the water outlet.

[0010] Preferably, the water inlet pipe, sewage pipe and water outlet pipe are all provided with grooved pipe joints for connecting with pipelines.

[0011] Preferably, the rotatable valve handle of the manual three-way valve extends out of the pipeline.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] This manually controlled laminated filter adopts a manual three-way valve to replace the traditional three-way pipe. When backwashing is needed, just turn the valve handle of the manual three-way valve to move the valve core upward to seal the water inlet and open the sewage outlet. At this time, the water outlet and the sewage outlet are connected to realize the backwashing function. Compared with the traditional solution, each unit has two fewer fasteners, which greatly reduces the problem of water leakage at the interface caused by the sealing problem of the fasteners. Each unit only needs to switch and adjust a manual three-way valve to realize the backwashing of the equipment. Manual operation is also more convenient than the traditional solution.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 In this embodiment, a manually controlled laminated filter is provided, comprising a laminated filter unit 1, a water inlet pipe 2, a sewage pipe 4 and a water outlet pipe 5. The bottoms of the water inlet pipe 2 and the water outlet pipe 5 are provided with a metal foot cup bracket 12 for supporting the entire laminated filter; an axial pressure gauge 9 and an exhaust valve 8 are installed on the water inlet pipe 2 at one end away from the water inlet; a plug 6 and a radial pressure gauge 3 are installed on the water outlet pipe 5 at one end away from the water outlet; a grooved pipe joint 11 for connecting with a pipeline is reserved on the water inlet pipe 2, the sewage pipe 4 and the water outlet pipe 5; In the figure, the laminated filter unit 1 is located above the outlet pipe 5, the laminated filter unit 1 is connected to the sewage pipe 4 and the water inlet pipe 2 through a manual three-way valve 10, the manual three-way valve 10 and the pipeline interface are connected through a grooved pipe joint 11, the rotatable valve handle of the manual three-way valve 10 extends out of the pipeline, and the connection or closing of the sewage outlet and the water outlet is achieved by moving the valve core of the manual three-way valve 10, wherein the structure and principle of the manual three-way valve 10 have been disclosed in the existing patent CN219827804U, which will not be repeated here.

[0025] Compared with the prior art, the utility model uses two fewer fasteners per unit than the traditional solution, which greatly reduces the problem of water leakage at the interface caused by the sealing problem of the fasteners. The manual operation of the utility model is also more convenient than the traditional solution. Each unit only needs to switch and adjust a manual three-way valve 10 to achieve the backwashing of the equipment. In the traditional solution, each unit needs to switch two manual butterfly valves, and this type of butterfly valve often fails to close tightly due to high pressure.

[0026] See also Figure 4-5 Working principle: The utility model adopts a manual three-way valve 10 to replace the three-way pipe of the traditional design. When backwashing is needed, just turn the valve handle of the manual three-way valve 10 to move the valve core upward to seal the water inlet of the water inlet pipe 2 and open the sewage outlet of the sewage pipe 4. At this time, the water outlet of the water outlet pipe 5 is connected with the sewage outlet of the sewage pipe 4, thereby realizing the backwashing function. The utility model is not only limited to the use of laminated filters, but can also be used in the occasions of sewage treatment three-way valves to realize sewage treatment (such as sand and gravel filters, shallow filters...).
