Description

Technical Field

[0001] The utility model relates to the technical field of samplers, in particular to an industrial sewage sampler with a filtering function. Background Art

[0002] In the field of industrial wastewater monitoring, the purity of the sample during sampling directly affects the accuracy of the test data, so there are high requirements for the filtration performance of the sampling device. The filtration structure of existing industrial wastewater samplers generally has the following defects:

[0003] First, the filtration layer design is simple, often using a single-layer filter screen or filter element. Because industrial wastewater contains a complex impurity composition, including large suspended particles (such as debris and fibers), micro-colloids, and soluble organic pollutants, a single filtration layer is difficult to achieve graded interception. This results in large impurities easily clogging the filter channel, while micro-pollutants cannot be effectively removed, affecting sample purity.

[0004] Second, the deep purification is insufficient. Existing devices mostly focus on physical interception, and have limited effects on removing odor, pigments and some organic pollutants in sewage. There are still certain pollutants remaining in the filtered water samples, which makes it difficult to meet the sample purity requirements of high-precision testing.

[0005] Therefore, there is an urgent need for an industrial wastewater sampling device that has graded filtration capabilities and can achieve deep purification to solve the above-mentioned defects of the prior art. Utility Model Content

[0006] In order to overcome the shortcomings mentioned in the background technology, the utility model provides an industrial sewage sampler with a filtering function.

[0007] An industrial sewage sampler with a filtering function includes a sampling cylinder, a connecting pipe, a piston block, a connecting rod and a compression spring. The bottom of the sampling cylinder is connected and communicated with a connecting pipe. The lower side of the sampling cylinder is sealed and slidably connected with the piston block. The top of the piston block is connected to the connecting rod. The upper end of the connecting rod passes through the top of the sampling cylinder. A compression spring is connected between the lower end of the connecting rod and the top of the sampling cylinder. The compression spring is sleeved on the outer periphery of the connecting rod. It also includes a filter cylinder, a float, a float, an activated carbon filter element, a guide rod, a guide cylinder, a scraper cylinder and an inlet and outlet control component. The sampling cylinder The outer side of the lower part is connected to a scraper cylinder, the top of the scraper cylinder is symmetrically connected to a guide cylinder, the guide cylinder is slidably connected to a guide rod, a filter cylinder is connected between the bottoms of the two guide rods, and a through hole matching the size of the connecting pipe is opened in the middle of the top of the filter cylinder. The two form a sliding connection relationship, the filter cylinder and the inner wall of the scraper cylinder slide together, a floating block is embedded in the bottom of the filter cylinder, and a plurality of floating balls are connected to the bottom of the floating block at intervals along the circumference, an activated carbon filter element is connected to the middle of the filter cylinder, and the bottom end of the activated carbon filter element is connected to the top surface of the floating block, and an inlet and outlet control component is provided on the floating block.

[0008] In addition, it is particularly preferred that the inlet and outlet control assembly includes a connecting pipe, a check ball 1, a reset spring, a check ball 2 and a connecting spring. A connecting pipe is connected to the middle of the top of the float. The connecting pipe is located on the inner side of the activated carbon filter element. The connecting pipe is slidably connected to the inside of the connecting pipe. A check ball 1 is connected to the outer side of the upper end of the connecting pipe. The check ball 1 is sealed with the lower water inlet of the connecting pipe. A reset spring is connected between the top of the filter cartridge and the bottom of the sampling cartridge. The reset spring is sleeved on the outer periphery of the connecting pipe. The lower end of the connecting pipe passes through the bottom of the float. The lower port of the connecting pipe is slidably connected to a support rod through a bracket. A check ball 2 is fixedly connected to the middle of the support rod. The check ball 2 is sealed with the lower port of the connecting pipe, and a connecting spring is fixedly connected between the top of the check ball 2 and the bracket. The connecting spring is sleeved on the outer periphery of the support rod.

[0009] In addition, it is particularly preferred that a paper filter element is further included, the outer side of the upper end of the connecting pipe is sleeved with the paper filter element, and the paper filter element is embedded in the lower end of the connecting pipe.

[0010] In addition, it is particularly preferred that a floating plate is further included, and the floating plate is fixedly installed on the outer periphery of the lower part of the filter cartridge.

[0011] In addition, it is particularly preferred that the sampling tube is made of a transparent material.

[0012] In addition, it is particularly preferred that scale lines are further included, and scale lines are engraved on the right side wall of the sampling tube along the axial direction.

[0013] The beneficial effects of this utility model are as follows: 1. Large impurities in sewage are initially intercepted by the outer wall of the filter cartridge, and then a first-level deep filtration (adsorption of organic pollutants, odor, etc.) is achieved through the activated carbon filter element, and finally a second-level fine filtration (removal of tiny suspended particles) is completed through the paper filter element. The synergistic effect of the three-stage filtration greatly improves the purity of the sample liquid, meeting the requirements of subsequent test on sample cleanliness.

[0014] 2. The floating block, floating ball and floating plate form a composite buoyancy structure, which significantly improves the buoyancy response speed and load-bearing capacity of the filter cartridge, ensuring that the filter cartridge can move upward quickly and stably when the device is immersed in sewage; the sliding cooperation between the guide rod and the guide cylinder further limits the displacement trajectory of the filter cartridge, avoids deflection, and ensures the structural stability during the sampling process.

[0015] 3. The transparent sampling tube allows for intuitive observation of the sampling liquid status. The scale lines on the side wall allow for accurate reading of the sampling volume, enabling on-demand quantitative sampling and improving operational convenience and sample quantification accuracy.

[0023] Example: An industrial wastewater sampler with filtering function, such as Figures 1-6The filter element 8 is provided with a guide rod 13, a filter element 14 and a filter element 15. The filter element 8 is provided with a guide rod 13, a filter element 14 is provided with a guide rod 14, a filter element 15 is provided with a guide rod 13 ... 6 slides with the inner wall of the scraper cylinder 15, and a floating block 7 is embedded in the bottom of the filter cylinder 6. A plurality of floating balls 71 are connected to the bottom of the floating block 7 at intervals along the circumference. An activated carbon filter element 8 is connected to the middle of the filter cylinder 6, and the bottom end of the activated carbon filter element 8 is connected to the top surface of the floating block 7. An inlet and outlet control component is provided on the floating block 7. A scale line 19 is engraved on the right side wall of the sampling cylinder 1 along the axial direction. The sampling cylinder 1 is made of transparent material, which is convenient for real-time observation of the liquid level and turbidity of the sampled liquid inside the sampling cylinder 1, providing an intuitive judgment basis for the sampling operation. By reading the value corresponding to the scale line 19, the volume of the sampled liquid in the sampling cylinder 1 can be accurately obtained, so as to achieve on-demand accurate sampling and meet the quantitative requirements of different detection scenarios. A floating plate 18 is fixedly installed on the outer periphery of the lower part of the filter cylinder 6. The floating plate 18 can effectively increase the buoyancy coefficient of the entire filter cylinder 6. When the device is immersed in sewage, it can ensure that the filter cylinder 6 quickly responds to the buoyancy and moves upward, significantly improving the operating stability of the device.

[0024] like Figure 2 and Figure 4-Figure 6As shown, the inlet and outlet control components include a connecting pipe 9, a check ball 10, a paper filter element 11, a reset spring 12, a check ball 2 16 and a connecting spring 17. The middle of the top of the floating block 7 is connected with a connecting pipe 9, the connecting pipe 9 is located inside the activated carbon filter element 8, the connecting pipe 9 is slidably connected to the inside of the connecting pipe 2, the outer side of the upper end of the connecting pipe 9 is connected with a check ball 10, the check ball 10 is sealed with the lower water inlet of the connecting pipe 2, a reset spring 12 is connected between the top of the filter cartridge 6 and the bottom of the sampling cartridge 1, the reset spring 12 is sleeved on the outer periphery of the connecting pipe 2, the lower end of the connecting pipe 9 passes through the bottom of the floating block 7, and the lower end of the connecting pipe 9 is slidably connected to a support rod through a bracket. The top of the connecting tube 2 is fixedly connected with a check ball 16, which is sealed with the lower port of the connecting tube 9, and a connecting spring 17 is fixedly connected between the top of the check ball 16 and the bracket. The connecting spring 17 is sleeved on the outer periphery of the support rod. In the initial state, the length of the support rod extends to the outside of the lower port of the connecting tube 9, which is convenient for applying operating force to the support rod. A paper filter element 11 is sleeved on the outer side of the upper end of the connecting tube 9. The paper filter element 11 is embedded in the lower port of the connecting tube 2 (that is, in the connecting channel between the filter cartridge 6 and the connecting tube 2). When the sampling liquid filtered by the filter cartridge 6 and the activated carbon filter element 8 enters the connecting tube 2, it flows through the paper filter element 11 for secondary filtration in sequence, and then enters the connecting tube 2 and the inside of the sampling tube 1.

[0025] When sampling industrial wastewater, the device is immersed in the wastewater from top to bottom in the vertical direction. During the immersion process, the float 7 and the float ball 71 come into contact with the wastewater. Under the buoyancy of the wastewater, the float 7 drives the filter cartridge 6 to move upward, the reset spring 12 is gradually compressed, and the guide rod 13 slides axially along the guide cylinder 14 to achieve the guide positioning of the filter cartridge 6. The filter cartridge 6 simultaneously drives the inlet and outlet control assembly to move upward, wherein the check ball 10 moves upward accordingly to break away from the sealing fit state of the lower port of the connecting pipe 2, and the wastewater passes through the filter cartridge. 6 After entering and intercepting large impurities, they are first filtered through the activated carbon filter element 8 for a deep level, then enter the connecting pipe 2 and complete the secondary fine filtration through the paper filter element 11, and finally temporarily stored in the connecting pipe 2. At the same time, during the upward movement of the filter cartridge 6, its outer wall is tightly fitted with the inner wall of the scraper cartridge 15, and the scraper cartridge 15 realizes the real-time removal of impurities attached to the outer wall of the filter cartridge 6. After the channel of the connecting pipe 2 is opened, the operator pulls up the connecting rod 4, drives the piston block 3 to move upward, compresses the compression spring 5, and uses the piston block 3 moves upward and the negative pressure generated draws the filtered sample liquid in the connecting tube 2 into the sampling cylinder 1; after the sampling volume reaches the standard, the device is taken out of the sewage, the float 7 and the float 71 are separated from the buoyancy of the sewage, the reset spring 12 elastically resets and drives the filter cylinder 6 to move downward, and its upper parts reset synchronously, the connecting tube 9 drives the check ball 10 to move downward and re-form a sealing fit with the lower end of the connecting tube 2. If the sampling liquid in the sampling cylinder 1 needs to be discharged for collection, the operator pushes the support rod connected to the check ball 16 upward to make the connecting spring 1 7 is compressed, and the check ball 16 moves up and out of the sealing cooperation state of the lower end of the connecting pipe 9. At this time, the negative pressure state inside the sampling cylinder 1 is released, and the compression spring 5 elastically resets to drive the connecting rod 4 and the piston block 3 to move downward. The piston block 3 pushes the sampling liquid in the sampling cylinder 1 into the connecting pipe 2 and is discharged downward through the channel of the connecting pipe 9; after the sampling liquid is collected, the branch rod is released, and the connecting spring 17 elastically resets to drive the check ball 16 and the branch rod to move down and reset, and the check ball 16 forms a sealing cooperation with the lower end of the connecting pipe 9 again.
