Description

Technical Field

[0001] The present invention relates to the technical field of salt spray detection equipment, and particularly to a performance detection device based on filter materials. Background Art

[0002] A salt spray test chamber is an experimental equipment that artificially simulates a salt spray corrosion environment. By atomizing a brine solution with a specific concentration and evenly spraying it onto the surface of the sample to be tested, the corrosion resistance of the material or protective coating is evaluated;

[0003] When filter materials are produced, they all need to pass through a salt spray test chamber for salt spray testing, and then the corrosion resistance of the filter materials is detected.

[0004] In order to ensure the accuracy of the test, the lid of the existing salt spray test chamber is set to be inclined. The inclined surface structure can make the condensed water generated in the chamber slide along the cover surface to the edge, avoiding directly dripping onto the surface of the sample and preventing non-natural corrosion or distortion of the test results;

[0005] In actual work, it is necessary to observe the filter materials during the experiment. However, due to the attachment of salt spray droplets on the lid, it will cause the staff to be unable to directly observe the change state of the filter materials. In order to avoid this problem in the prior art, an auxiliary exhaust port is set to eliminate the attached salt spray. However, in actual work, the defogging effect of the auxiliary exhaust port is very limited, and the staff is still very fuzzy when observing. Moreover, the auxiliary exhaust port will also extract the salt spray in the chamber, and the salt spray will be disturbed during the extraction process, affecting the free fall motion of the salt spray, thus causing deviation in the detection data of the filter materials.

Detailed implementation mode

[0067] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which the presently preferred embodiments of the invention are shown. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the invention to those skilled in the art.

[0068] Embodiment 1

[0069] A performance detection device based on a filter material, as Figures 1-15 shown, comprising a detection box 1, a defogging system 2 and a driving component 3;

[0070] The detection box 1 includes a test component 10 and an opening and closing observation cover 11. The test component 10 has a receiving cavity with an opening. The opening and closing observation cover 11 can be flipped to close or open the opening. A bevel symmetric about the center axis is provided on the side of the opening and closing observation cover 11 facing away from the test component 10.

[0071] The defogging system 2 includes at least two defogging components provided on the side of the opening and closing observation cover 11 facing away from the test component 10;

[0072] The driving component 3 includes a power component 101 provided on the opening and closing observation cover 11 and a transmission part 102 connected to the power component 101;

[0073] Among them, the driving component 3 can drive each demisting component to move along the inclined plane in a direction away from the central axis, and the demisting component clears and drains the attached droplets on the inclined plane of the opening and closing observation cover 11 under the drive of the driving component 3.

[0074] The demisting component located on one side of the opening and closing observation cover 11 includes: a scraping component 104, a hollow flow-through plate 105, a liquid collection component 106, and a rotating water-absorbing member 107;

[0075] The scraping component 104 is jointly connected by a transmission member 102 on one side of the opening and closing observation cover 11, and the scraping component 104 is in contact with the inclined plane of the corresponding opening and closing observation cover 11 on one side;

[0076] The hollow flow-through plate 105 is connected to the scraping component 104, and the hollow flow-through plate 105 is provided with a through hole at both ends and is hollow;

[0077] The liquid collection component 106 is fixedly connected to the hollow flow-through plate 105, and a blocking portion 1061 is provided on the side of the liquid collection component 106 away from the hollow flow-through plate 105;

[0078] A plurality of rotating water-absorbing members 107 are connected to the liquid collection component 106, and a flow groove is provided on the surface of each rotating water-absorbing member 107; the rotating water-absorbing members 107 are all in contact with the corresponding opening and closing observation cover 11.

[0079] The rotating water-absorbing member 107 includes at least two drainage working groups, [[ID=I9]]

[0080] The drainage working group includes at least two rotating water-absorbing members 107 arranged at intervals in a straight line array in the first direction x;

[0081] And at least two drainage working groups are arranged on the liquid collection component 106, and the drainage working groups are arranged at intervals in the second direction y, and two adjacent drainage working groups are arranged in a staggered interval.

[0082] (For the convenience of description, as Figure 2 shown, let the direction pointed by the arrow in the first direction x be "left", the direction pointed by the arrow in the second direction y be "rear", and the direction pointed by the arrow in the third direction z be "upward")

[0083] In the actual work of the prior art, salt spray droplets will adhere to the box cover, resulting in that the staff cannot directly observe the change state of the filter material. The auxiliary mist exhaust port set in the prior art has limited defogging effect, and will also disturb the salt spray during the extraction process, affecting the free-fall motion of the salt spray, so that the detection data of the filter material is deviated;

[0084] (For the convenience of description, the defogging component located at the front of the opening and closing observation cover 11 is described hereinafter. The actual working principle of the defogging component at the rear of the opening and closing observation cover 11 is the same as that of the front defogging component, only the working orientation is different.)

[0085] Therefore, the device is provided with a defogging system 2. When the staff needs to observe the detection state of the test specimen in the detection box 1, the power component 101 starts to work and drives all the front transmission parts 102 connected thereto to start working. When the front transmission part 102 works, it drives the corresponding connected defogging component to move downward along the inclined surface of the opening and closing observation cover 11. At this time, the scraping part 104 in contact with the inclined surface of the opening and closing observation cover 11 scrapes the salt spray droplets adhering to the inclined surface of the opening and closing observation cover 11 during the movement. At this time, the salt spray droplets form a liquid flow, which sequentially flows along the upper inclined surface of the scraping part 104 and the hollow flow plate 105 to the liquid collecting part surrounded by the blocking part 1061 to form salt solution. In this way, the salt spray droplets adhering to the inclined surface of the opening and closing observation cover 11 are removed, enabling the staff to quickly observe the state of the test specimen.

[0086] However, when the scraping part 104 scrapes the salt spray droplets, although most of the liquid flow can flow along the scraping part 104 and the hollow flow plate 105 to the liquid collecting part surrounded by the blocking part 1061, due to the fact that when the salt spray droplets are scraped by the scraping part 104, the formed liquid flow is larger than the liquid flow that naturally slides along the inclined surface of the opening and closing observation cover 11. In this way, there will be many liquid flows in strands, showing Figure 14 the sliding liquid flow 001 as shown, which then crosses the liquid collecting part and drops onto the test specimen, still affecting the test result.

[0087] Therefore, the device is also provided with a rotating water-absorbing part 107. When the defogging system 2 moves, since the rotating water-absorbing part 107 is arranged in front of the scraping part 104 and the rotating water-absorbing part 107 is in contact with the inclined surface of the opening and closing observation cover 11, when the sliding liquid flow 001 flows in the state shown Figure 15 it will first contact several rotating water-absorbing parts 107. The rotating water-absorbing part 107 is provided with a flow-through groove, and the sliding liquid flow 001 will flow along the flow-through groove to the liquid collecting part surrounded by the blocking part 1061. In this way, the problem that the sliding liquid flow 001 drops onto the test specimen and affects the test is avoided.

[0088] Embodiment 2

[0089] On the basis of Embodiment 1, as Figures 8-9 shown

[0090] the defogging component of the opening and closing observation cover 11 further includes a telescopic conveying pipe 108.

[0091] Both ends of the liquid collecting component 106 are communicated with one end of at least one telescopic conveying pipe 108 respectively, and the other end of each telescopic conveying pipe 108 penetrates through the opening and closing observation cover 11 and is communicated with the outside.

[0092] The rotating water absorbing member 107 includes a capillary water absorbing block 1071 and blades 1072;

[0093] The capillary water absorbing block 1071 passes through the liquid collecting component 106 through a rotating shaft and extends along the direction of the test component 10. A flow channel is arranged on the surface of the capillary water absorbing block 1071, and the rotating shaft of the capillary water absorbing block 1071 is rotatably connected with the liquid collecting component 106;

[0094] The blades 1072 are fixedly connected to the rotating shaft of the capillary water absorbing block 1071, and the blades 1072 are located in the cavity of the liquid collecting component 106.

[0095] In the prior art, when performing salt spray tests, different test pieces are tested for different durations. Under long-term tests, the water content of the salt spray droplets on the inclined plane will be greater. And when the sliding liquid flow 001 flows through the flow channel of the rotating water absorbing member 107 to the liquid collecting part surrounded by the blocking part 1061, since the sliding liquid flow 001 continuously flows onto the flow channel of the capillary water absorbing block 1071, when the flow channel of the capillary water absorbing block 1071 is saturated with liquid storage, the sliding liquid flow 001 will precipitate from the capillary water absorbing block 1071, and the capillary water absorbing block 1071 cannot timely drain the sliding liquid flow 001 to the liquid collecting part. At this time, the sliding liquid flow 001 will still cross the liquid collecting part, which will also cause the sliding liquid flow 001 to affect the test piece.

[0096] Therefore, the present device is also provided with telescopic conveying pipes 108. Before the device works, several telescopic conveying pipes 108 are respectively connected to an external pump. When the demisting system 2 starts to move and work, several external pumps located on the same side (either the left or the right side) of the device are set as the first-station pumps, and the first-station pumps start to work synchronously to input the medium. The external flowing medium (such as water and air) is input into the hollow cavity of the liquid collecting component 106 through the telescopic conveying pipes 108. And several external pumps on the other side of the device are set as the second-station pumps, and the second-station pumps start to work to output the medium and discharge the flowing medium in the liquid collecting component 106. In this way, under the cooperation of the first-station pumps and the second-station pumps, the flowing medium can form a turbulent flow. Driven by the turbulent flow, the blades 1072 start to rotate, and then drive the connected capillary water absorbing block 1071 to rotate. During the rotation of the capillary water absorbing block 1071, the sliding liquid flow 001 in the flow channel can be thrown out into the liquid collecting part surrounded by the blocking part 1061. In this way, the problem that the sliding liquid flow 001 precipitates from the capillary water absorbing block 1071 and the sliding liquid flow 001 still crosses the liquid collecting part, resulting in the sliding liquid flow 001 affecting the test piece can be avoided;

[0097] Furthermore, after the testing of the device is completed, the external pumps can continue to operate, forming turbulence in the hollow cavity of the liquid collecting component 106 to drive the capillary water absorption block 1071 to rotate. In this way, after the device is completed, the capillary water absorption block 1071 can throw out the sliding liquid flow 001 attached to the surface during rotation, so that no sliding liquid flow 001 will remain in the flow groove of the capillary water absorption block 1071. This avoids the problem that the residual sliding liquid flow 001 evaporates water to form salt scale attached to the flow groove when the device is not performing testing, thereby affecting the flow diversion of the flow groove;

[0098] Furthermore, the capillary water absorption block 1071 is configured in a conical shape, and the lower portion of the capillary water absorption block 1071 is located in the liquid collecting portion surrounded by the barrier portion 1061. In this way, when the sliding liquid is swung, it will follow the inertial motion in the tangential direction of the capillary water absorption block 1071, that is, it will be swung out from the lower portion of the capillary water absorption block 1071. The swung sliding liquid will not splash over the top of the barrier portion 1061 and fall onto the test specimen.

[0099] Example 3

[0100] On the basis of Example 2, Figures 6-9 As shown,

[0101] The demisting assembly located on one side of the opening and closing observation cover 11 further includes: a telescopic component 20 and a positioning rod 103;

[0102] The telescopic component 20 is provided on the corresponding liquid collecting component 106;

[0103] At least one positioning rod 103 is provided at both ends of the driving assembly 3, and each positioning rod 103 passes through the corresponding demisting assembly;

[0104] The telescopic component 20 includes:

[0105] At least one first elastic member 201 is fixedly connected to the cavity where the liquid collecting member 106 is disposed;

[0106] At least one telescopic strip 202 is fixedly connected to the plurality of first elastic members 201 at the same horizontal position when viewed from the direction of the test assembly 10 when the viewing cover 11 is opened and closed, and the telescopic strip 202 extends through the inner top surface of the liquid collecting component 106;

[0107] At least one extension portion 2021 is provided on the telescopic bar 202 , and each of the positioning rods 103 contacts the corresponding extension portion 2021 . The positioning rod 103 is provided with at least one extrusion block 1031 .

[0108] During the actual working process, the capacity of the liquid collecting part surrounded by the blocking part 1061 is limited. When the liquid collecting part is filled with brine, the brine will overflow from the liquid collecting part, causing the brine to drip onto the test piece. Since the liquid collecting part is recessed, after the defogging component finishes working, the brine received by the liquid collecting part also needs to be discharged immediately to ensure the normal operation of the next work.

[0109] Therefore, the device is also provided with a telescopic component 20 and a pressing block 1031. When the defogging component at the front of the device moves to the position of the pressing block 1031 during operation, as Figure 9 shown, the pressing block 1031 contacts and presses the extension part 2021 of the telescopic strip 202 at the corresponding position. At this time, the telescopic strip 202 moves downward under the force, and at this time, the first elastic member 201 is compressed and contracted by the telescopic strip 202 and generates a reset elastic force. At this time, the through hole 1062 is exposed, and the received brine will flow into the cavity of the liquid collecting component 106 from the through hole 1062. At this time, several external pumps are still working, and there is still a turbulent flow of the flowing medium in the cavity of the liquid collecting component 106. At this time, because the flow rate of the flowing medium is relatively faster than the external environment, the received brine can be quickly sucked into the cavity of the liquid collecting component 106, and then the received brine can be quickly discharged through the second-stage pump.

[0110] Moreover, the defogging component keeps moving continuously. When the defogging component moves to the position where the extension part 2021 disengages from the contact with the pressing block 1031, the first elastic member 201 releases the reset elastic force, thereby driving the telescopic strip 202 to reset. In this way, the turbulent flow of the flowing medium can no longer be sucked in, so that the free fall motion of the salt mist during the test work of the device will not be affected, avoiding the prior art

[0111] Embodiment 4

[0112] On the basis of Embodiment 3, as Figures 10-13 shown,

[0113] The hollow flow-through plate 105 located on one side of the opening and closing observation cover 11 further includes: a first blocking component 30 and a second blocking component 31;

[0114] The first blocking component 30 includes a first sealing strip 301 in contact with the inner bottom surface of the hollow flow-through plate 105, and a second elastic member 302 that enables the first sealing strip 301 to move, and a first limiting strip 303 provided on the side of the first sealing strip 301 close to the liquid collecting component 106;

[0115] The second blocking component 31 includes a second sealing strip 311 in contact with the inner top surface of the hollow flow-through plate 105, and a third elastic member 312 that enables the second sealing strip 311 to move, and a second limiting strip 313 provided at the rear of the second limiting strip 313;

[0116] Moreover, the hollow flow-through plate 105 is provided with a through hollow structure with both ends open; and the first sealing strip 301 and the second sealing strip 311 are in contact and abutted against each other statically to form a sealing plate, and the sealing plate is used to seal the flow-through opening 1051 of the hollow flow-through plate 105.

[0117] When the driving assembly 3 drives the demisting assembly to reset, since the scraping member 104 is in inclined contact with the opening and closing observation cover 11, during the reset process of the scraping member 104, it will still scrape the salt spray droplets newly attached to the inclined surface of the opening and closing observation cover 11, thus still forming a liquid flow and dripping on the test specimen to affect the test result.

[0118] Therefore, the hollow flow-through plate 105 of this device is provided with an upper opening and a hollow structure. When the demisting assembly resets, the liquid flow will flow along the rear part of the scraping member 104 and flow from the flow-through opening 1051 into the cavity of the hollow flow-through plate 105. In this way, it can avoid the problem that during the reset process of the scraping member 104, it will still scrape the salt spray droplets newly attached to the inclined surface of the opening and closing observation cover 11 to form a liquid flow and drip on the test specimen to affect the test result.

[0119] Furthermore, after the hollow flow-through plate 105 has been working for a long time, a large amount of salt solution will accumulate in the cavity, and at this time, it needs to be discharged.

[0120] Therefore, this device is provided with a second barrier assembly 31. When it is necessary to discharge the salt solution in the hollow flow-through plate 105, all the external pumps start to pump, reducing the air pressure in the cavity of the liquid collection member 106. At this time, affected by the pressure difference of the second sealing strip 311, it moves towards the liquid collection member 106. At this time, the hollow flow-through plate 105 is communicated with the liquid collection member 106, and the salt solution in the hollow flow-through plate 105 can flow into the liquid collection member 106 and then be discharged from several external pumps.

[0121] Embodiment 5

[0122] On the basis of Embodiment 4, as Figures 10-13 shown,

[0123] The scraping member 104 includes a connecting block 1041, a hollow strip 1042, an elastic sheet 1043 and a water spraying port 1044;

[0124] At least one connecting block 1041 is connected to the corresponding transmission member 102;

[0125] The hollow strip 1042 is fixedly connected by the connecting blocks 1041 on the same side of the opening and closing observation cover 11, and the hollow strip 1042 is provided with a hollow structure with one end open;

[0126] The elastic sheet 1043 is fixedly connected to the hollow strip 1042;

[0127] At least two water spray nozzles 1044 are provided on the elastic sheet 1043, and the water spray nozzles 1044 all penetrate through the elastic sheet 1043.

[0128] The defogging assembly located on one side of the opening and closing observation cover 11 further includes a closing assembly 40;

[0129] The closing assembly 40 is provided at one end of the hollow flow plate 105 close to the opening and closing observation cover 11;

[0130] The closing assembly 40 includes a pressing strip 401, a rotating piece 402 and a driving block 403;

[0131] At least one pressing strip 401 is respectively connected to both ends of the first sealing strip 301;

[0132] At least one rotating piece 402 is respectively connected to the hollow flow plate 105, and the rotating piece 402 is rotatably connected to the hollow flow plate 105 through a torsion spring;

[0133] At least one driving block 403 is respectively connected to both ends of the rotating piece 402;

[0134] Wherein, when the pressing strip 401 is pushed by the first sealing strip 301, it can press the corresponding driving block 403, so that the rotating piece 402 rotates and unfolds to block the opening at one end of the hollow flow plate 105 close to the opening and closing observation cover 11.

[0135] In actual work, since salt spray droplets adhere to the opening and closing observation cover 11, after the salt spray droplets evaporate, salt scale will form and adhere to the opening and closing observation cover 11 again. Therefore, in order to ensure the visibility of the opening and closing observation cover 11, the inner wall surface of the opening and closing observation cover 11 needs to be cleaned after each use of the device, especially the inclined surface of the opening and closing observation cover 11. However, cleaning it after each experiment is very cumbersome, and it is difficult to clean the inclined surface cleanly with the existing cleaning tools and cleaning methods.

[0136] Therefore, the device further includes a closing assembly 40. When the device needs to be cleaned, the transmission member 102 drives the connected defogging assembly to start moving, and all external pumps work synchronously to input continuous cleaning liquid into the cavity of the liquid collecting component 106. Thus, as the cleaning liquid is continuously input, the pressure of the cleaning liquid in the cavity of the liquid collecting component 106 increases. When the pressure of the cleaning liquid reaches the preset value, it will push the first sealing strip 301 to move towards the flow port 1051 direction, that is, the first sealing strip 301 changes from Figure 11 state to Figure 12 state, and when the first sealing strip 301 moves, as Figure 12As shown, the first sealing strip 301 drives the connected extrusion strip 401 to move towards the driving block 403 until the extrusion strip 401 presses the driving block 403 to rotate. The rotation of the driving block 403 drives the connected rotating piece 402 to rotate until the rotating piece 402 changes from Figure 11 state to Figure 12 state. At this time, the rotating piece 402 seals the flow port 1051.

[0137] Meanwhile, the first sealing strip 301 disengages from the second sealing strip 311. At this time, the cavity of the hollow flow plate 105 is communicated with the cavity of the liquid collecting component 106. The cleaning liquid flows from the liquid collecting component 106 into the cavity of the hollow flow plate 105. And since the flow port 1051 is blocked at this time, the cleaning liquid will flow into the cavity of the hollow strip 1042 from the lower opening of the hollow strip 1042. Then the high-pressure cleaning liquid will break through the water spraying holes 1044 on the elastic piece 1043 and spray the cleaning liquid on the inclined surface of the opening and closing observation cover 11 at the corresponding position. And at this time, the defogging is continuously moving. In this way, the cleaning liquid can clean the entire inclined surface of the opening and closing observation cover 11, thus avoiding the problem that in the prior art, it is very cumbersome to clean it after each experiment, and it is very difficult for the existing cleaning tools to clean the inclined surface clean.

[0138] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
