DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described below by specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0024] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0026] Example: Figures 1 to 5 As shown, a deep filtration device is mainly composed of a filter fixture, a filter unit and a filter partition 6. The purpose of designing the filter fixture is mainly to facilitate the installation and placement of the filter unit. Specifically, the filter fixture includes a bottom plate 1 and a pressure plate 2. The filter unit is installed between the bottom plate 1 and the pressure plate 2 of the filter fixture. The filtering action of the filter unit is achieved by applying pressure to the pressure plate 2. In order to achieve multi-stage filtration for the same feed liquid or to perform a single filtration for different feed liquids, thereby improving the filtration efficiency, the filter units in this embodiment are at least two, and the filter partition 6 is arranged between two adjacent filter units, and the two adjacent filter units can be stacked up and down. The filter partition 6 is used to ensure the flatness of each filter unit, thereby reducing the probability of problems such as instability caused by direct contact between filter units or the inlet and outlet pipe interfaces of different filter units affecting each other and being unable to be placed.

[0027] The number of the filter baffles 6 is set according to the number of the filter units. If the number of the filter units is n, the number of the filter baffles 6 is n-1, or multiple filter baffles 6 are set between two adjacent filter units. Specifically, the number of filter baffles 6 can be reasonably adjusted according to the required distance between the filter units. The filter units and the filter baffles 6 are installed on the filter fixture in a horizontal state.

[0028] The single filter unit in this embodiment is mainly composed of a liquid inlet cover plate 3, a liquid outlet cover plate 4 and a filter membrane package 5 having a liquid inlet hole and a liquid outlet hole. At least one of the filter membrane packages 5 can be stacked between the liquid inlet cover plate 3 and the liquid outlet cover plate 4 to achieve filtering of the feed liquid. In order to improve the filtering efficiency, the filtering accuracy between the multiple filter units in this embodiment can be designed to be the same, that is, multiple filter units can be used to filter the same feed liquid. Or the filtering accuracy of multiple filter units can be designed differently. For example, the primary filter unit may use a filter membrane package 5 with a lower filtering accuracy to remove larger particles, while the secondary filter unit uses a filter membrane package 5 with a high filtering accuracy to remove finer impurities, thereby ensuring the filtering accuracy and filtering effect. In order to achieve the above-mentioned filtering function and allow multiple filter units to feed through one feed port, in this embodiment, the liquid outlet cover plate 4 of at least one filter unit is connected to the liquid inlet cover plate 3 of other filter units.

[0029] The overall shape of the filter baffle 6 is a hollow cylinder, or an annular cylinder. The upper and lower planes must be level and smooth, with a levelness of less than 0.05 mm / m. Since it is installed between two filter units, its levelness is critical. If the upper and lower surfaces of the filter baffle 6 are not in a horizontal state, the filter unit installed above it will tilt, which will not only increase the risk of leakage, but may even cause the center of gravity to become unstable and collapse in any direction. The outer diameter of the filter baffle 6 is 70%-95% of the outer diameter of the filter membrane package 5, and the height of the filter baffle 6 is 10-60 mm. The upper and lower outer circles of the filter baffle 6 can be designed to be chamfered or rounded, so as to achieve a smooth transition between the upper and lower planes and the sides of the filter baffle 6. The outer diameter of the filter baffle 6 must be greater than 70% of the outer diameter of the filter membrane package 5, so as to ensure that the filter baffle 6 has a large enough area, and the filter baffle 6 surface will not be crushed or even deformed due to excessive pressure during the compression and sealing process of the filter clamp; the outer diameter of the filter baffle 6 must be less than 95% of the outer diameter of the filter membrane package, otherwise there will be a risk of interference with the outer edge of the liquid inlet cover plate 3 or the liquid outlet cover plate 4, and the clamping force of the clamp will be transmitted from the outer edge of the liquid inlet cover plate 3 or the liquid outlet cover plate 4, which may cause the seal to fail. The height of the filter baffle 6 must be greater than 10mm. A sufficient height can separate the cover plates of adjacent deep filtration units by a sufficient distance, and sufficient space will be left on the cover plates to install joints and pipelines. The height of the filter baffle 6 is less than 60mm, which will reduce the weight of the filter baffle 6. At the same time, since the height of the clamp is fixed, the height of the filter baffle 6 is too high, which may compress the height space of the deep filtration unit and may not be able to install more filter membrane packages 5. The outer edges of the upper and lower surfaces of the filter baffle 6 are chamfered or rounded, which can also avoid cutting the operator during installation. At the same time, the chamfered or rounded corners also make it convenient for the operator to disassemble and install the filter baffle 6.

[0030] In order to facilitate operation, reduce the difficulty of operation, and ensure the stability of the entire filtration system, thereby ensuring the filtration effect, the above-mentioned filtration fixture also includes a support rod 7, and the side of the above-mentioned filter membrane package 5 is formed with a sleeve portion 8 that can be sleeved on the above-mentioned support rod 7. In this embodiment, there are three above-mentioned support rods 7, and the three above-mentioned support rods 7 are arranged in a triangle shape, which has high stability. The three above-mentioned support rods 7 are also equipped with a support platform 9 that can be compacted above the above-mentioned pressing plate 2. The above-mentioned support platform 9 is located above the above-mentioned pressing plate 2 and is connected to the above-mentioned pressing plate 2 through an adjusting rod 10 to adjust the position of the above-mentioned pressing plate 2. A top plate 11 is installed on the top of the three above-mentioned support rods 7. In order to facilitate installation and reduce the difficulty of installation, the above-mentioned support platform 9 is provided with a through hole for the support rod 7 to pass through, and is provided with a through hole for the adjusting rod 10 to pass through. The top of the support rod 7 is fixed to the top plate 11, and the support platform 9 can move along the support rod 7. A rotating rod 12 capable of adjusting the position of the supporting platform 9 between the bottom plate 1 and the top plate 11 is provided below the top plate 11. In order to further ensure the stability of the filtering system during the filtering process, the rotating rod 12 is vertically installed below the top plate 11, and the support rod 7 is arranged parallel to the rotating rod 12. A lifting platform 13 is also installed on the rotating rod 12. The rotating rod 12 and the lifting platform 13 are matched through a screw transmission, that is, when the rotating rod 12 rotates, the lifting platform 13 can move along the rotating rod 12 to control the movement of the supporting platform 9, and then drive the adjusting rod 10 through the supporting platform 9 to drive the pressing plate 2 at the uppermost end in the downward direction to achieve compression, thereby achieving filtering.

[0031] The material of the filter partition 6 is any one of PP (polypropylene), PA (nylon), PE (polyethylene), PVC (polyvinyl chloride), PVDF (polyvinylidene fluoride), stainless steel and aluminum, which is easy to process and shape, has high strength and is not easy to deform.

[0032] In order to ensure the structural strength of the bottom of the filtration system, a support plate 14 is provided at the bottom of the bottom plate 1. In order to facilitate the movement of the filtration system, a rolling assembly 15 is installed at the bottom of the support plate 14. Specifically, the rolling assembly 15 can be a universal wheel with a brake, which is convenient for position movement and needs to be automatic to avoid movement during the filtration process, thereby enhancing the user experience.

[0033] A deep filtration device in this embodiment has a compact and ingenious structure of the filtration system. By setting a filtration fixture, a filtration unit and a filtration partition 6, the filtration unit includes a liquid inlet cover plate 3, a liquid outlet cover plate 4 and a filtration membrane package 5. When there is only one filtration unit, the liquid inlet cover plate 3 and the liquid outlet cover plate 4 are distributed at both ends of the filtration membrane package 5, respectively contacting the bottom plate 1 and the pressure plate 2 in the filtration fixture, and the liquid inlet holes of the multiple filtration membrane packages 5 are correspondingly connected to each other, and the liquid outlet holes are correspondingly connected to each other, thereby completing a single filtration of multiple parallel filtration membrane packages 5. When there are multiple filtration units, a single filtration unit can be used to filter different feed liquids, or multiple filtration units can be connected in series for multi-stage filtration of the same feed liquid. The above method is simple to operate, can reduce the space occupied by the equipment, and can reduce the user's use cost and procurement cost, enhance the user's experience, and is conducive to the promotion and application of the above deep filtration device in the field of filtration technology.
