Description

Technical Field

[0001] The utility model relates to the technical field of suma tanks, in particular to a suma tank maintenance device. Background Art

[0002] Summa can: An air sampling can used to collect and store VOC gases (volatile organic compounds) as specified by the US EPA air monitoring regulations. The inner surface of the can is silanized and passivated to ensure that the components remain stable during storage. The valve is usually a high-quality, metal-to-metal sealed, stainless steel film 2 / 3-turn valve. The valve and transmission line are mostly heated to ensure the elimination of sample retention.

[0003] In the prior art, when using the Suma can, the valve needs to be opened or closed frequently. There is a risk of damage to the valve during use, which reduces the air tightness of the Suma can. However, the location of the valve damage is usually inside the valve, which makes it difficult for relevant technicians to find it. When the Suma can is used for sampling, the air collected in the Suma can will overflow from the valve, making it difficult for the Suma can to sample smoothly. To this end, we provide a Suma can maintenance device. Utility Model Content

[0036] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0037] See also Figure 1-6 The utility model provides a technical solution: a Suma tank maintenance device, comprising a water storage column 1 with an opening at the top, an air inlet 11 connecting the inside and outside of the water storage column 1 is opened at the bottom of the water storage column 1, and a water absorption part is provided at the top of the water storage column 1, and the top opening of the water storage column 1 is covered by the water absorption part, and the color of the water absorption part changes after absorbing water.

[0038] The air inlet 11 is arranged on the side wall of the bottom end of the water storage column 1, and an air guide tube 42 is arranged on the air inlet 11. One end of the air guide tube 42 is fixedly connected and communicated with the air inlet 11, and the other end is fixedly connected and communicated with a connector 43. An internal thread that matches the external thread on the output end of the valve is provided on the inner circumferential surface of the connector 43, so that the air guide tube 42 can be installed on the Suma tank by simply aligning the connector 43 with the output end of the valve and screwing it in, and a passage for air flow between the valve and the inside of the water storage column 1 is formed, which is simple and convenient to operate; a single air guide tube 42 is fixedly connected at the air inlet 11 The one-way valve is a one-way valve, the input end of the one-way valve is connected and communicated with the end of the air pipe 42 facing away from the connecting head 43 through threaded cooperation, and the output end is fixedly connected and communicated with the air inlet 11, and the water in the water storage column 1 is restricted from flowing into the air pipe 42 through the stop valve; a hook 431 is fixedly connected to the outer wall of the connecting head 43, and a hanging ring 432 is fixedly connected to the side of the outer wall of the water storage column 1 facing the connecting head 43, and the air pipe 42 can be folded and stored by hanging the hook 431 on the hanging ring 432, thereby reducing the space occupied by the maintenance device for easy carrying.

[0039] The water absorbing part includes a water absorbing material, which is a color-changing latex containing cobalt chloride, which has extremely strong water absorption; the color-changing latex is blue when it is not absorbing water, and gradually turns to light red as the amount of water absorbed increases after absorbing water. The water storage column 1 is made of transparent acrylic material to facilitate observation of the height of the water level in the water storage column 1. At the same time, when the air in the air guide tube 42 enters the water storage column 1, a certain amount of bubbles will be generated, which visually reminds relevant technical personnel.

[0040] During use, the air guide tube 42 is removed from the input end of the one-way valve, and water is injected into the water column 1 from the one-way valve, so that the water level in the water column 1 is higher than the height of the air inlet 11, so that the air entering the water column 1 is always below the water level; the end of the air guide tube 42 facing away from the connector 43 is fixed and sealed on the input end of the one-way valve, and the connector 43 is threadedly connected with the output end of the valve on the Suma tank to form a passage for air flow between the valve and the inside of the water column 1. When the valve is damaged and the sealing is poor, the air in the Suma tank overflows from the valve, and then passes through the air guide tube 42 and the one-way valve in turn into the inside of the water column 1, and then enters the water and floats with part of the water, and finally floats to contact with the color-changing latex. The cobalt chloride component on the color-changing latex absorbs the water in the air, and then gradually changes from blue to light red, further visually reminding the relevant technical personnel to assist the relevant technical personnel in determining the damage of the valve, so that the sampling work of the Suma tank can proceed smoothly.

[0041] In this embodiment: the water absorption part includes a partition 12 fixedly connected to the inner wall of the water storage column 1, and a containing frame 21 for containing water absorption material, and the partition 12 is provided with an air outlet 13 connecting the inside and outside of the water storage column 1;

[0042] The outer bottom surface of the containing frame 21 is in contact with the top surface of the partition 12, and the containing frame 21 is rotatably matched with the water storage column 1;

[0043] The bottom wall of the containing frame 21 is provided with an air vent 22, and the air outlet 13 is located on the rotation track of the air vent 22;

[0044] A locking assembly is provided between the containing frame 21 and the water storage column 1 , and the containing frame 21 is restricted from freely rotating on the water storage column 1 by the locking assembly.

[0045] During use, when using the inspection device for detection work, the containing frame 21 is rotated forward to make the containing frame 21 and the partition 12 move relative to each other, and then the vent hole 22 and the air outlet hole 13 approach each other until they overlap, so as to form a channel for the air inside the water column 1 to enter the containing frame 21, and then the air overflowing from the Suma tank enters the containing frame 21 after humidification, and contacts and reacts with the color-changing latex in the containing frame 21.

[0046] After the detection work is completed, the containing frame 21 is rotated in the opposite direction to make the containing frame 21 and the partition 12 move relative to each other, so that the vent hole 22 and the air outlet hole 13 move away from each other until they are completely separated, so as to block the passage of the air inside the water storage column 1 into the containing frame 21, and reduce the amount of water in the water storage column 1 that enters the containing frame 21 after natural evaporation.

[0047] In this embodiment: the containing frame 21 is a cylindrical frame structure with an opening at the top, and a cover 23 is connected to the top of the containing frame 21 to cover the top opening of the containing frame 21, and the cover 23 is made of a transparent material;

[0048] A first exhaust hole 24 is opened on the side wall of the containing frame 21, and a second exhaust hole 14 is opened on the top side wall of the water storage column 1. When the vent hole 22 overlaps with the air outlet hole 13, the first exhaust hole 24 overlaps with the second exhaust hole 14.

[0049] The cover 23 is provided to limit the color-changing latex from freely moving out of the containing frame 21, and the cover 23 is made of a transparent acrylic material, so as to facilitate observation of the color change of the color-changing latex in the containing frame 21. At the same time, the first exhaust hole 24 and the second exhaust hole 14 are provided, and the air enters the containing frame 21 through the overlap of the vent hole 22 and the air outlet hole 13 to form a channel, and the air is discharged from the containing frame 21 through the overlap of the first exhaust hole 24 and the second exhaust hole 14, and the two channels are connected or blocked at the same time.

[0050] During use, when testing is required, the containing frame 21 is rotated forward so that the vent hole 22 overlaps with the air outlet hole 13 to form a channel for air to enter the containing frame 21; at the same time, the first exhaust hole 24 overlaps with the second exhaust hole 14 to form a channel for air to be discharged from the containing frame 21, so that the pressure in the containing frame 21 remains unchanged, so that the air in the water storage column 1 can continue to carry moisture into the containing frame 21, and then the air tightness of the valve can be tested.

[0051] After the detection is completed, the containing frame 21 is rotated in the opposite direction to separate the vent hole 22 from the air outlet hole 13 to block the passage of air in the water storage column 1 into the containing frame 21. At the same time, the first exhaust hole 24 is separated from the second exhaust hole 14 to block the passage of external air into the containing frame 21, so that the containing frame 21 is in a sealed state, reducing the influence of external air on the color-changing latex in the containing frame 21.

[0052] In this embodiment, the outer circumferential surface of the sealing cover 23 is provided with an external thread, the inner wall of the containing frame 21 is provided with an internal thread, and the sealing cover 23 and the containing frame 21 are connected by threaded cooperation.

[0053] The cover 23 is threadably connected to the containing frame 21 to facilitate taking out the color-changing latex in the containing frame 21. The color-changing latex is heated after absorbing water so that the color-changing latex gradually turns blue, and the color-changing latex is recycled for detection.

[0054] In this embodiment: the vent hole 22 is provided with one, the axis of the vent hole 22, the axis of the first exhaust hole 24 and the axis of the containing frame 21 are located on the same plane, and the vent hole 22 and the first exhaust hole 24 are respectively located on both sides of the axis of the containing frame 21.

[0055] In this embodiment, the vent hole 22 and the first exhaust hole 24 are both covered and fixedly connected with a screen 15 .

[0056] By arranging the vent hole 22 and the first exhaust hole 24 on both sides of the axis of the containing frame 21 respectively, the straight-line distance between the vent hole 22 and the first exhaust hole 24 is made the farthest, and when the air outlet hole 13 overlaps with the vent hole 22, the air in the water storage column 1 entering the containing frame 21 contacts with the color-changing latex around the vent hole 22, causing the color-changing latex around the vent hole 22 to change color; at the same time, the first exhaust hole 24 overlaps with the second exhaust hole 14, so that external air can enter the containing frame 21, causing the color-changing latex around the first exhaust hole 24 to change color, so as to facilitate observation and further analysis to obtain the damage condition of the valve.

[0057] In this embodiment: the locking assembly includes a slider 31 and a spring 32, the slider 31 and the side wall of the containing frame 21 slide together in the radial direction of the containing frame 21, and the side of the slider 31 facing away from the partition 12 protrudes from the top surface of the containing frame 21;

[0058] One end of the spring 32 is fixedly connected to the end of the slider 31 facing the containing frame 21, and the other end is fixedly connected to the outer wall of the containing frame 21. When the spring 32 is in a naturally extended state, the end of the slider 31 facing away from the containing frame 21 abuts against the inner wall of the water storage column 1.

[0059] The top of the inner wall of the water storage column 1 is provided with two grooves 16 , which are arranged along the circumference of the containing frame 21 , and when the vent hole 22 coincides with the air outlet hole 13 , the end of the slider 31 facing away from the containing frame 21 is inserted into one of the grooves 16 .

[0060] A receiving groove 33 is formed on the outer circumferential surface of the containing frame 21 , and one end of the slider 31 facing the containing frame 21 is slidably matched with the receiving groove 33 , and the spring 32 is embedded in the receiving groove 33 , making the structure more stable.

[0061] During use, when inspection is required, the slider 31 is manually pushed toward the axial direction of the containing frame 21, so that the spring 32 is squeezed and deformed to store energy, and then the slider 31 is pushed into the storage groove 33, and the containing frame 21 is rotated forward to make the vent 22 coincide with the air outlet 13, and then the inspection work is carried out. At the same time, the spring 32 releases energy to push the slider 31 to be inserted into one of the grooves 16, and then under the obstruction of the side wall of the groove 16, the free rotation of the slider 31 and the containing frame 21 is limited, so that the inspection device can stably perform the inspection work.

[0062] After the inspection is completed, the slider 31 is manually pushed toward the axial direction of the containing frame 21 again, and the spring 32 is squeezed and deformed again to store energy, and then the slider 31 is pushed into the storage groove 33, and the containing frame 21 is rotated in the opposite direction to separate the vent 22 from the air outlet 13, thereby completing the inspection work. At the same time, the spring 32 releases energy to push the slider 31 into another groove 16, and then under the obstruction of the side wall of the groove 16, the free rotation of the slider 31 and the containing frame 21 is limited, so that the inside of the containing frame 21 remains sealed.

[0063] In this embodiment: the bottom end of the water storage column 1 is provided with a connecting portion for connecting to a Suma tank.

[0064] The connecting part is a suction cup 41 fixedly connected to the water storage column 1. The specific model of the suction cup 41 is Yuanhan Industrial-HSP-50-3. When installing the maintenance device on the Summa tank, you only need to press the suction cup 41 to exhaust the air in the suction cup 41, and the water storage column 1 can be fixedly installed on the Summa tank through the adsorption effect of the suction cup 41. The operation is simple and convenient.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
