Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a sedimentation filter suitable for continuous sampling. Background Technology

[0002] In fields such as environmental monitoring, water quality analysis, and hydrological surveys, water samples need to be filtered to remove suspended particles, silt, and other impurities to ensure the accuracy of subsequent testing data. Currently, water sampling filtration technology is mainly developed around two major needs: "sedimentation separation" and "continuous operation." However, existing technologies still have significant shortcomings and are difficult to meet the requirements of efficient and stable filtration in uninterrupted sampling scenarios.

[0003] Currently, there are two common types of water sampling and filtration devices on the market. One type uses a pump as a power source to force the sampled water through multiple sets of filter membranes. The water sample that passes through the filter membranes is the water sample to be tested. This type of filtration device has high filtration efficiency but requires frequent manual replacement of the filter membranes, and the amount of water sample filtered is relatively small, resulting in high operation and maintenance costs. The other type is a multi-stage sedimentation and filtration device consisting of multiple sedimentation tanks connected in series. This device can operate for a long time without maintenance and requires lower maintenance costs. However, it requires a large area to lay multiple sedimentation tanks, resulting in higher construction costs, longer filtration time, and significant sampling lag.

[0004] Therefore, there is an urgent need for a sedimentation filter that is simple in structure, highly efficient and stable, and suitable for continuous sampling. Utility Model Content

[0005] The present invention aims to provide a sedimentation filter suitable for continuous sampling, so as to overcome the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a sedimentation filter suitable for continuous sampling, including a water pump, a sedimentation bottle, a multi-way valve, and a sandwich plate. The sedimentation bottle is provided with multiple sandwich plates arranged alternately along the axial direction of the sedimentation bottle for sedimentation and separation of impurities in the water. The bottom of the sedimentation bottle is provided with an inlet located below the sandwich plate, and an outlet pipe is provided above the sandwich plate. The water pump is connected to the inlet via a flexible hose. One channel of the multi-way valve is connected to the end of the outlet pipe away from the sandwich plate, and another channel of the multi-way valve is connected to a sampling tube. A filter membrane assembly is provided on the sampling tube.

[0007] Furthermore, in the aforementioned sedimentation filter suitable for continuous sampling, multiple sandwich plates are staggered and inclined upward along the axial direction of the sedimentation bottle to form an S-shaped flow channel.

[0008] Furthermore, in the aforementioned sedimentation filter suitable for continuous sampling, the inclination angle of the sandwich plate is 45°-60°.

[0009] Furthermore, in the aforementioned sedimentation filter suitable for continuous sampling, one end of the sandwich plate is fixedly connected to the side wall of the sedimentation bottle, and the other end extends toward the center of the sedimentation bottle, with the extended end of the sandwich plate extending toward the center passing over the center of the sedimentation bottle.

[0010] Furthermore, in the aforementioned sedimentation filter suitable for continuous sampling, the sandwich panel has at least four layers.

[0011] Furthermore, in the aforementioned sedimentation filter suitable for continuous sampling, the filter membrane assembly comprises at least one filter membrane.

[0012] Furthermore, the aforementioned sedimentation filter suitable for continuous sampling also includes a buffer cover, which is positioned above the inlet to disperse and slow down the water flow, and the sandwich plate is positioned above the buffer cover. Additionally, the extended end of the sandwich plate completely extends beyond the buffer cover.

[0013] Furthermore, in the aforementioned sedimentation filter suitable for continuous sampling, the sedimentation bottle is a closed cavity, the outlet pipe is fixed to the top of the sedimentation bottle, one end of the outlet pipe extending into the sedimentation bottle is spaced apart from the uppermost sandwich plate, and one channel of the multi-way valve is connected to the end of the outlet pipe extending outside the sedimentation bottle.

[0014] Furthermore, in the aforementioned sedimentation filter suitable for continuous sampling, the multi-way valve is a three-way valve, with the second channel of the multi-way valve being a normally closed end and the third channel of the multi-way valve being a normally open end, connected to the waste discharge pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the sedimentation filter of this utility model has a multi-stage sedimentation filtration function, and occupies a small area, has high filtration efficiency, and low operation and maintenance costs; and by setting an airtight sedimentation bottle, the water pumping of the sedimentation bottle and the water pumping of the sampling tube are realized through a power source (water pump), which can reduce maintenance needs and reduce filtration costs.

Detailed Implementation

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 like Figure 1 As shown, a sedimentation filter suitable for continuous sampling includes a water pump 1, a sedimentation bottle 2, a multi-way valve 3, and a sandwich plate 4. The sedimentation bottle 2 has multiple sandwich plates 4 arranged alternately along the axial direction of the sedimentation bottle 2 for sedimentation and separation of impurities in the water. The bottom of the sedimentation bottle 2 has an inlet 5 located below the sandwich plate 4, and an outlet pipe 6 is located above the sandwich plate 4. The water pump 1 is connected to the inlet 5 through a hose. The first channel 31 of the multi-way valve 3 is connected to the end of the outlet pipe 6 away from the sandwich plate 4, and the second channel 32 of the multi-way valve 3 is connected to the sampling tube 7. The sampling tube 7 is equipped with a filter membrane assembly 8.

[0020] In the above structure, multiple sandwich plates 4 are staggered and inclined upwards along the axial direction of the sedimentation bottle 2, forming an S-shaped flow channel. For example... Figure 1 As shown in the diagram, the red line represents the water flow path. Multiple sandwich plates 4 guide the water flow in an S-shape upwards. During this process, impurities in the water will settle onto the sandwich plates 4 according to their weight. Impurities with a density less than that of the water sample will float to the top and overflow or be discharged, achieving a multi-stage filtration effect. Furthermore, since the water flow direction in the sedimentation bottle 2 is upwards, the water flow will adhere to the bottom surface of the sandwich plates 4 and will not carry away the impurities settled on the sandwich plates 4, thus improving the sedimentation and filtration effect.

[0021] There are at least four sandwich plates 4, which can be set according to the water quality to ensure sedimentation efficiency. In this embodiment, there are six sandwich plates 4.

[0022] like Figure 1 As shown, to achieve the best sedimentation and filtration effect, the tilt angle of the sandwich plate 4 relative to the horizontal plane is 30°-45°, that is, the angle θ between the sandwich plate 4 and the axial direction (i.e., the vertical direction) of the sedimentation bottle 2 is 45°-60°.

[0023] One end of the sandwich plate 4 is fixedly connected to the side wall of the sedimentation bottle 2, and the other end extends toward the center of the sedimentation bottle 2. The extended end of the sandwich plate 4 extends past the center of the sedimentation bottle 4, so that the water flow forms a large curved S-shaped flow channel, which can improve the sedimentation and filtration effect.

[0024] This invention achieves multi-stage sedimentation filtration by using multiple sandwich plates, reducing the workload of the filter module, thereby reducing the frequency of filter membrane replacement, reducing maintenance needs, and the filter bottle has a small footprint and high filtration efficiency, which greatly reduces operation and maintenance costs.

[0025] The filter membrane module 8 includes at least one filter membrane. It may include one filter membrane or multiple filter membranes with different or the same filtration capacity, depending on the water quality, to reduce operation and maintenance costs while ensuring filtration effect.

[0026] like Figure 1 As shown, the aforementioned sedimentation filter also includes a buffer cover 9, which is positioned above the inlet 5 to disperse and slow down the water flow. A sandwich plate 4 is positioned above the buffer cover 9. Furthermore, the extended end of the sandwich plate 4 completely extends beyond the buffer cover 9.

[0027] Example 2 Based on the structure of Example 1, such as Figure 1 As shown, the sedimentation bottle 2 is a closed cavity, and the water outlet pipe 6 is fixed to the top of the sedimentation bottle 2. The end of the water outlet pipe 6 that extends into the sedimentation bottle 2 is spaced apart from the uppermost sandwich plate 4. This spacing ensures that the water outlet does not carry away the impurities that have settled on the uppermost sandwich plate. The channel 31 of the multi-way valve 3 is connected to the end of the water outlet pipe 6 that extends out of the sedimentation bottle 2.

[0028] Multi-way valve 3 is a three-way valve. Channel 2 32 of multi-way valve 3 is normally closed, and channel 3 33 of multi-way valve 3 is normally open, which is connected to waste discharge pipe 10.

[0029] Since the sedimentation bottle 2 is a closed cavity, it is airtight. The channel 33 of the multi-way valve 3 is normally open. When not sampling, the waste discharge pipe 10 continuously discharges water. At this time, the discharge volume of the waste discharge pipe 10 is equal to the inlet volume of the water inlet. The water level in the sedimentation bottle 2 is maintained at the inlet at the bottom of the outlet pipe 6, and the impurities floating on the water surface will be discharged. When sampling is required, the channel 2 32 is switched to the open state. Due to the resistance of the filter membrane group 8, the inlet volume of the water inlet will be greater than the sampling volume. The water level in the sedimentation bottle 2 rises, and the floating matter layer rises to above the inlet of the outlet pipe 6, which can reduce the impurities in the sample and further reduce the filtration volume of the filter membrane group, greatly reducing the replacement frequency of the filter membrane.

[0030] The sedimentation filter of this utility model has multi-stage sedimentation filtration function, small footprint, high filtration efficiency, and low operation and maintenance cost; by setting an airtight sedimentation bottle, water is pumped from the sedimentation bottle and the sampling tube through a single power source (water pump), which can reduce maintenance needs and lower filtration costs.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
