Description

Technical Field

[0001] The utility model belongs to the technical field of filters, in particular to a filtering performance testing device for a pulsating flow filter. Background Art

[0002] The filter is an indispensable device on the pipeline for conveying media. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, water level valve, Fanggong filter and other equipment. The filter consists of a cylinder, a stainless steel filter, a sewage discharge part, a transmission device and an electrical control part. After the water to be treated passes through the filter cartridge of the filter screen, its impurities are blocked. When cleaning is required, just take out the detachable filter cartridge and reinstall it after treatment. Therefore, it is very convenient to use and maintain. During the use of the filter, it is usually necessary to use a filtration performance test device to test the filtration performance to ensure the filtration efficiency of the fluid and avoid the blockage of the filtration structure causing excessive hydraulic pressure, which in turn causes damage to the filtration structure. However, it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN215677592U discloses a filter pulsation filtration accuracy test device, the bottom liquid outlet of the test oil tank is connected with a test pump 1, a three-way valve 1, a test piece, a regulating valve 1, a flow meter 1, a radiator 1 and a liquid inlet on the top of the test oil tank in sequence through a pipeline, the pipeline between the test pump 1 and the test piece is connected with a liquid inlet particle counter through a pipeline and a two-position four-way valve 1, and the pipeline between the test piece and the regulating valve 1 is connected with a liquid outlet particle counter through a pipeline and a two-position four-way valve 2. Although the filtration accuracy test device can test the filtration accuracy of the filter for multiple performances, such a precise instrument is not required to test the filtration performance in actual use of the filter, the use cost and maintenance expenses of the test device are high, and the scope of application is narrow;

[0004] When testing the filtering performance of a filter, a simple testing device usually first tests the unfiltered fluid, then filters the fluid through the filter, and then tests the filtered fluid. The operation is time-consuming and labor-intensive, and it is difficult to perform real-time testing of the filtering performance of a filter that is being used for a long time. The test results are relatively delayed and difficult to represent the filtering performance of the filter in use. Utility Model Content

[0005] The utility model aims to provide a pulsating flow filter filtering performance testing device, which solves the problems that more sophisticated filtering performance testing devices are complex in structure, have high costs and maintenance expenses, and have a narrow scope of use, while simple testing devices are difficult to perform real-time detection of the fluid passing through the filter, and the test results are relatively lagging and difficult to represent the filtering performance of the filter in use, through a feed pipe and a detection bottle.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a pulsating flow filter filtering performance testing device, comprising a feeding pipe and a detection bottle, wherein the outer circumference of the feeding pipe is clamped with a sealing rotating pipe, the outer circumference of the feeding pipe is clamped with a rotating motor, the outer circumference of the sealing rotating pipe is screwed with a detection bottle, one end of the detection bottle is clamped with a cylinder, and a sealing pressing plate is slidably clamped in the detection bottle;

[0008] A testing device is installed at the liquid inlet and outlet of the filter. When the fluid is filtered through the filter, the fluid first enters a feed pipe, and the rotating motor drives the detection bottle to rotate in the vertical direction, so that the detection bottle can sample the fluid at various positions passing through the feed pipe to ensure the accuracy of the test results. The sealing pressure plate is driven by the cylinder to move, so that the fluid can quickly enter the detection bottle for collection, thereby improving the degree of automation of the device. After sampling the fluid, the detection bottle rotates to the bottom of the feed pipe, and the fluid in the detection bottle can be weighed through the pressure sensing component on one side of the sealing pressure plate. At the same time, the testing device located at one end of the liquid outlet of the filter samples and weighs the filtered fluid, and the real-time filtering performance of the filter is judged by the difference in weight. After the test is completed, the sealing pressure plate can be driven by the cylinder to move in the opposite direction to make the detected fluid flow back to the feed pipe, which does not affect the normal use of the filter. The device has a simple structure and a small size, which reduces costs and maintenance expenses.

[0009] Furthermore, a first threaded tube is welded through the outer circumference of the sealing rotating tube, a plurality of material passing holes are opened through the outer circumference of the material passing tube, and the first threaded tube is attached to the outer circumference of the material passing holes;

[0010] The detection bottle can sample the fluid passing through different positions of the feed pipe through the feed holes located at different positions of the feed pipe to ensure the accuracy of the test results.

[0011] Furthermore, mounting plates are welded and fixed at both ends of the outer circumference of the feed pipe, and a driving roller is rotatably clamped at one end of the rotating motor, and the driving roller is meshed with the outer circumference of the sealed rotating tube;

[0012] By passing bolts through and screwing them onto the mounting plate, the two feeding pipes can be connected to the liquid inlet and the liquid outlet of the filter respectively. When sampling the fluid, the driving roller can be driven to rotate by rotating the motor, which further drives the sealing rotating tube to rotate, so that the detection bottle can be moved to different positions for sampling, thereby improving the degree of automation of the device.

[0013] Furthermore, a second threaded tube is welded through one end of the detection bottle, the second threaded tube is located at the other end of the detection bottle relative to the cylinder, and the second threaded tube is screwed and fixed to the outer peripheral surface of the first threaded tube;

[0014] When sampling, the cylinder can drive the telescopic tube to extend and retract, and further drive the sealing pressure plate to move along the detection bottle, so that the fluid passing through the feed pipe is sucked into the detection bottle, which is convenient for testing the sampled fluid and improves the convenience of the device.

[0015] Further, one end of the cylinder is slidably connected with a telescopic tube, the sealing pressure plate is connected with the other end of the telescopic tube relative to the cylinder, one side of the sealing pressure plate is connected with a pressure sensing component, the other side of the pressure sensing component is connected with a positioning block, and the positioning block is inserted into the first threaded tube;

[0016] After the fluids before and after filtration are sampled through the test device, the test bottle is moved to the bottom of the feed pipe, and the fluid in the test bottle is weighed through the pressure sensor component. The real-time filtering performance of the filter is judged by the weight difference, and after the test is completed, the cylinder can drive the sealing plate to move in the reverse direction to make the tested fluid flow back into the feed pipe, which does not affect the normal use of the filter. The device has a simple structure and a small size, which reduces costs and maintenance expenses.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that although the filtration accuracy test device can perform multiple performance tests on the filtration accuracy of the filter, such a precise instrument is not needed to test the filtration performance when the filter is actually used, the use cost and maintenance expenses of the test device are high, and the scope of application is narrow by arranging a detection bottle. When the device performs a filtration performance test, after the fluid is sucked into the detection bottle, the weight of the fluid in the detection bottle can be monitored by the pressure sensor component, and the filtration performance of the filter can be judged by sampling and detecting the fluid before and after filtration and by the weight difference of the same volume of fluid. The device has a simple structure and a small size, and reduces costs and maintenance expenses.

[0019] The utility model solves the problem that when a filter performance test device tests the filtering performance of a filter passing through the filter, a simple test device usually first tests the unfiltered fluid, then filters the fluid through the filter, and then tests the filtered fluid, which is time-consuming and laborious to operate, and it is difficult to perform real-time detection of the filtering performance of the filter that is being used for a long time, and the test result is relatively delayed and difficult to represent the filtering performance of the filter in use. When the device tests the filtering performance, it only needs to drive the sealing rotating tube and the detection bottle to rotate by a rotating motor, and at the same time drive the sealing pressing plate to move by a cylinder to sample the fluid passing through the feed pipe, and after the detection, the sealing pressing plate is driven by the cylinder to move in the opposite direction to make the detected fluid flow back into the feed pipe, which does not affect the normal use of the filter, and can test the filtering performance of the filter at any time to ensure the accuracy of the filtering performance of the filter.

[0029] A testing device is installed at the liquid inlet and the liquid outlet of the pulsating flow filter respectively. When the filter is in use, the fluid first passes through a feed pipe 1 and then enters the filter for filtration. The filtered fluid then passes through another feed pipe 1 and enters the next device. When it is necessary to test the filtering performance of the filter, the rotating motor 102 drives the sealing rotating tube 101 to rotate in the vertical direction, and further drives the detection bottle 2 to rotate. At the same time, the cylinder 201 drives the sealing pressing plate 204 to slide along the detection bottle 2, and samples the fluid passing through each position of the feed pipe 1. After the detection bottle 2 is filled, the detection bottle 2 is rotated to the bottom of the feed pipe 1, and the fluid in the detection bottle 2 is weighed by the pressure sensing component 205 on one side of the sealing pressing plate 204. The real-time filtering performance of the filter is judged by the weight difference of the fluid before and after filtration, and after the test is completed, the cylinder 201 drives the sealing pressing plate 204 to move in the opposite direction to make the detected fluid flow back to the feed pipe 1.

[0030] Among them Figure 1-3 As shown, a first threaded tube 103 is welded through the outer circumference of the sealed rotating tube 101, a plurality of material passing holes 106 are opened through the outer circumference of the feeding tube 1, the first threaded tube 103 is attached to the outer circumference of the material passing holes 106, mounting plates 105 are welded and fixed at both ends of the outer circumference of the feeding tube 1, a driving roller 104 is rotatably clamped at one end of the rotating motor 102, and the driving roller 104 is meshed with the outer circumference of the sealed rotating tube 101;

[0031] The two test devices are respectively fixed to the liquid inlet and the liquid outlet of the filter by means of bolts passing through and screwed to the mounting plate 105. When sampling the fluid, the rotating motor 102 drives the driving roller 104 to rotate, and further drives the sealed rotating tube 101 to rotate, so that the detection bottle 2 moves to different positions, and the fluid passing through the feeding tube 1 is sampled through the feeding holes 106 at different positions.

When the filter filters the fluid, the fluid first passes through a feed pipe 1 and then enters the filter for filtration, and the filtered fluid enters the next device through another feed pipe 1. When the filtering performance of the filter needs to be tested, the rotating motor 102 drives the driving roller 104 to rotate, and further drives the sealing rotating tube 101 rotates to move the detection bottle 2 to different positions. At the same time, the cylinder 201 drives the telescopic tube 203 to shrink, and further drives the sealing plate 204 to move along the detection bottle 2. The fluid passing through the feeding pipe 1 is sampled through the feeding holes 106 at different positions. After the detection bottle 2 is filled and moved to the bottom of the feeding pipe 1, the weight of the fluid in the detection bottle 2 is measured by the pressure sensing component 205.
