Description

Technical Field

[0001] This utility model belongs to the field of water-based ink filtration testing technology, and in particular relates to a water-based ink filtration testing device. Background Technology

[0002] Water-based ink is a type of water-soluble ink that is frequently used in spraying equipment. During operation, the ink is ejected from the nozzle of the spraying equipment. Because the nozzles on the equipment nozzles often have small diameters, it is essential to ensure that the ink is free of solid particles during operation; otherwise, the nozzle will become clogged and the equipment will not function properly.

[0003] Therefore, after the ink production is completed, the finished ink product needs to be tested for filtration performance. Ink with poor filtration performance is obviously due to the high content of solid particles in the ink. During the process of passing through the test filter, the filter is easily clogged. Therefore, if it is used directly on spraying, printing and other equipment, it is easy to damage the equipment.

[0004] In the production process, ink testing often involves pumping a sample of ink into a filter using a pump. If the ink can pass through the filter smoothly for a long time without clogging, it indicates that the ink contains few or no solid particles, and the ink quality is acceptable. However, current testing methods connect a single filter to the test pump. During testing, if the filter becomes clogged, the sudden increase in pressure can cause the filter to burst, leading to ink contamination. Furthermore, the ink waste generated during testing is difficult to manage centrally.

[0005] Meanwhile, industrially produced inks are produced in large batches, and the number of samples tested is also large. During the testing process, the inks need to pass through the filter within a certain time, meaning there are time requirements for the testing. Therefore, if the testing efficiency cannot be improved, the entire testing process will not only be time-consuming and labor-intensive, but also inefficient. Utility Model Content

[0006] Based on the above background, the purpose of this utility model is to provide a water-based ink filtration testing device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A water-based ink filtration testing device includes a test casing, inside which a plurality of filters are installed, and each filter has an inlet pipe and an outlet pipe.

[0009] An inner baffle is fixedly connected inside the cavity of the test casing, and the oil outlet pipe passes through the inner baffle.

[0010] The inner baffle plate divides the cavity of the test casing into a waste liquid cavity, and the discharge end of the oil outlet pipe is located in the waste liquid cavity;

[0011] The test casing is detachably fitted with a protective cover, and the oil inlet pipe passes through the protective cover.

[0012] The protective cover is equipped with a test pipe joint structure, which includes a guide rail fixedly connected to the protective cover, a movable push seat slidably connected to the guide rail, and a number of joint structures that mate with the oil inlet pipe installed on the movable push seat.

[0013] Preferably, the bottom of the test casing is connected to a waste discharge pipe, which is connected to the waste liquid chamber;

[0014] A valve is installed on the waste discharge pipe.

[0015] Preferably, a pressure gauge is installed on the oil inlet pipe.

[0016] Preferably, the test sleeve and the protective cover are detachably connected via a detachable connection structure.

[0017] Preferably, the detachable connection structure includes an annular female mounting flange integrally formed on the test casing opening;

[0018] The detachable connection structure also includes an annular sub-mounting flange integrally formed on the protective cover;

[0019] The annular female mounting flange and the annular male mounting flange are connected by a number of bolts.

[0020] Preferably, the connector structure includes a connector tube fixedly connected to a movable push base, and connector caps are respectively installed at the inlet and outlet ends of the connector tube, with the connector caps fastened to the oil inlet tube.

[0021] Preferably, the guide rail is threaded with a push nut for pushing the positioning and moving push seat.

[0022] Preferably, the filter includes a housing and a filter element installed within the housing.

[0023] Preferably, the inner baffle plate has several through holes, the oil outlet pipe passes through the through holes, and a sealing gasket is provided between the through holes and the oil outlet pipe.

[0024] This utility model has the following beneficial effects:

[0025] 1. During the testing process, several samples are pumped into the inlet pipe using corresponding liquid pumps. The ink is then filtered through a filter, specifically the filter element inside the filter housing. This method allows for the simultaneous testing of multiple samples, significantly improving testing efficiency. During the testing process, if the filter becomes clogged within the specified time, it indicates that the ink is substandard, meaning the particulate matter content is too high. The testing process not only allows for simultaneous testing of multiple samples, improving efficiency, but also ensures high safety. The protective cover and test casing greatly enhance the safety of the testing operation.

[0026] 2. The inner baffle divides the right end of the test casing into a waste liquid chamber to facilitate the storage of test waste liquid during the test process.

[0027] 3. During testing, when the filter becomes clogged, the pressure in the hydraulic system becomes extremely high. To prevent the connector cap from detaching from the inlet pipe (due to reduced stability of the threaded connection if the threaded structure is damaged), a push nut is threaded onto the guide rail to move and position the push seat. When the connector cap is tightened onto the inlet pipe, the push nut (with external threads on the guide rail) is turned and presses against the push seat. Under this pressing action, when the hydraulic pressure is high and the connector cap and connector pipe tend to detach from the inlet pipe, the push seat remains in a pressed-down state, preventing the connector cap and connector pipe from easily detaching from the inlet pipe, thus greatly improving the safety of the test.

[0028] 4. The connector tube and connector cover structure allow for convenient and quick connection of the testing equipment to the test filter. Attached Figure Description

[0039] Example 1

[0040] like Figure 1-5 As shown, a water-based ink filtration testing device includes a test casing 1, within which several filters 3 are installed. The filters 3 are conventional test filters disclosed in the prior art, and their main structure includes a cylindrical shell and filter elements installed within the shell. During the test, the ink passes through the filters 3. When the content of solid particles or other substances in the ink is too high, the filter elements are quickly clogged.

[0041] Similar to the existing filter 3, the filter 3 has an oil inlet pipe 31 and an oil outlet pipe 33 (the oil inlet pipe 31 and the oil outlet pipe 33 are connected to the housing of the filter 3).

[0042] Meanwhile, an inner baffle 2 is fixedly connected inside the cavity of the test casing 1, and the oil outlet pipe 33 passes through the inner baffle 2.

[0043] Specifically, the inner baffle 2 has several through holes, and the oil outlet pipe 33 passes through the through holes. According to the existing sealing method, a sealing gasket (not shown in the figure) is provided between the through holes and the oil outlet pipe 33. When the oil outlet pipe 33 passes through the through holes, the sealing performance is relatively high under the protection of the sealing gasket.

[0044] Meanwhile, when it is necessary to disassemble filter 3 (such as for replacement or cleaning), filter 3 can be pulled out directly from the inner baffle 2.

[0045] Under the action of the inner baffle 2, the inner baffle 2 divides the right end of the cavity of the test casing 1 into a waste liquid cavity (the main body of the filter 3 is placed at the left end of the cavity), and the discharge end of the oil outlet pipe 33 is located in the waste liquid cavity.

[0046] During the test, because the test needs to be conducted for a certain period of time, the ink generated during the test is temporarily stored in the waste liquid chamber to avoid ink contamination and to facilitate subsequent collection.

[0047] Correspondingly, the bottom of the test casing 1 is connected to a waste discharge pipe 11, which is connected to the waste liquid chamber; a valve is installed on the waste discharge pipe 111. The tested ink can be recovered by opening the valve.

[0048] During the test, when the filter 3 becomes clogged, the internal pressure of the filter 3 is very high. Therefore, the test casing 1 is detachably equipped with a protective cover 4 (the protective cover 4 ensures that even if the filter 3 is under high pressure and the filter 3 housing breaks open, the filter 3 is contained within the test casing 1, thus ensuring a very high level of safety during the test). The oil inlet pipe 31 passes through the protective cover 4 (the protective cover 4 also has a through hole, and a sealing gasket is placed inside the through hole).

[0049] Specifically, the test casing 1 and the protective cover 4 are detachably connected via a detachable connection structure. The detachable connection structure includes an annular female mounting flange 12 integrally formed on the opening of the test casing 1; the detachable connection structure also includes an annular male mounting flange 41 integrally formed on the protective cover 4; the annular female mounting flange 12 and the annular male mounting flange 41 are connected by a number of bolts.

[0050] This method facilitates the removal and installation of the protective cover 4. During testing, following existing testing methods, several samples are pumped into the inlet pipe 31 using their respective liquid pumps. The ink is then filtered through the filter 3, specifically through the filter element inside the filter housing. This method allows for the simultaneous testing of multiple samples, significantly improving testing efficiency.

[0051] During the test, if filter 3 becomes clogged within the specified test time, it indicates that the ink is unqualified and the particulate matter content in the ink is too high.

[0052] During the test, a pressure gauge 32 is installed on the oil inlet pipe 31 to monitor the pressure inside the filter 3. When the internal pressure is too high, the pressure value on the pressure gauge 32 on the oil inlet pipe 31 will increase suddenly, indicating that the filter element is severely clogged.

[0053] The above method enables simultaneous testing of multiple test samples, improving testing efficiency and ensuring high testing safety. Under the protection of the protective cover 4 and the test sleeve 1, the safety of the testing work is greatly improved.

[0054] Example 2

[0055] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, in order to facilitate a stable connection between the discharge pipe on the test pump body and the test filter 3 during the test, a test pipe joint structure is installed on the protective cover 4.

[0056] Specifically, the test pipe joint structure includes a guide rail 5 fixedly connected to the protective cover 4, a movable push seat 7 slidably connected to the guide rail 5, and several joint structures that cooperate with the oil inlet pipe 31 installed on the movable push seat 7.

[0057] Specifically, the connector structure includes a connector pipe 61 fixedly connected to the movable push base 7. Connector caps 62 are installed at both the inlet and outlet ends of the connector pipe 61. The connector caps 62 are conventional connector pipe caps disclosed in the prior art, and are identical to existing designs. The connector caps 62 are threaded onto the connector pipe 61, and their cap cavity walls have threaded structures. Correspondingly, the outer wall of the oil inlet pipe 31 also has threaded structures. When the connector cap 62 is screwed onto the oil inlet pipe 31, the oil inlet pipe 31 is connected. Similarly, the connector cap 62 at the other end is threaded onto the drain pipe on the test pump body, thus connecting the test equipment.

[0058] During operation, when filter 3 becomes clogged, the pressure in the hydraulic system becomes extremely high. To prevent the connector cover from detaching from the inlet pipe 31 (as the threaded structure is damaged, reducing the stability of the threaded connection), a push nut 51 is threaded onto the guide rail 5 to push the positioning movable push seat 7. When the connector cover 62 is tightened onto the inlet pipe 31, the push nut 51 is turned (the guide rail 5 has an external thread structure) and pressed against the movable push seat 7. Under this pressing action, when the hydraulic pressure is high, the connector cover 62 and connector pipe 61 tend to detach from the inlet pipe 31. However, because the movable push seat 7 is in a pressed state, the connector cover 62 and connector pipe 61 are not easily detached from the inlet pipe 31, thus greatly improving the safety of the test.

[0059] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
