Description

Technical Field

[0001] The present invention relates to a method for using a silica gel breather without disassembly, belonging to the technical field of silica gel breathers. Background Art

[0002] When two-thirds of the silica gel in the silica gel breather becomes discolored due to moisture absorption, it needs to be replaced according to regulations. The structure of a traditional silica gel breather includes a silica gel cylinder arranged in the middle, an oil cup arranged at the lower part of the silica gel cylinder, and a flange arranged at the top of the silica gel cylinder. The flange is fixed on the silica gel cylinder by bolts. When replacing the silica gel, the oil cup needs to be removed first, and then four connecting bolts on the flange need to be removed with a wrench. At this time, another staff member is required to cooperate to hold the silica gel cylinder by hand to prevent it from falling and being damaged after the bolts are removed. After removal, all the silica gel is poured out. Since the discolored and moisture-absorbed silica gel and the non-discolored and non-moisture-absorbed silica gel (with a diameter of about 5 mm) are mixed together after being poured out, they can only be recycled and processed. Only new silica gel can be refilled on-site. With the cooperation of two people, the breather is connected to the oil-filled equipment. Such a breather is troublesome to disassemble and assemble, has a high labor cost, and wastes silica gel.

[0003] To solve the problems existing in the traditional silica gel breather, the applicant applied for a Chinese patent "Layered Silica Gel Breather that Can Be Replaced Manually" in 2017. Refer to Figure 1 , this kind of breather uses a plurality of silica gel boxes 2' that are stacked and detachably connected in a glass cover 1'. Both the upper and lower surfaces of the silica gel box 2' are provided with holes, and silica gel particles are filled in layers. Utilizing the characteristic that the direction of silica gel getting wet is from bottom to top, when replacing the silica gel, the silica gel box 2' can be disassembled from the upper part, the wet silica gel in the lower part can be replaced, and then the silica gel box 2' is reinstalled into the glass cover 1' to realize the replacement of the silica gel.

[0004] However, the problem with the above-mentioned silica gel breather is that the silica gel box needs to ensure a tight fit with the inner wall of the glass cover so that all the air passes through the silica gel to play a dehumidifying role. But the tight fit between the silica gel box and the glass cover leads to the problem of high processing precision requirements for the silica gel box, which increases the cost. Because if the size of the silica gel box is processed too large, the friction force with the glass cover will be relatively large and it will be difficult to disassemble. If the size of the silica gel box is processed too small, there will be too large a gap between the silica gel box and the glass cover, resulting in the situation that the wet air can pass through the silica gel breather without passing through the silica gel, and the dehumidifying effect is poor. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: to provide a method for using a silica gel breather without disassembly to overcome the deficiencies of the prior art.

[0006] The technical solution of the present invention is: a method for using a silica gel breather without disassembly, and the method is as follows:

[0007] When filling silica gel, the silica gel box is not used, and the silica gel is directly filled into the glass cover;

[0008] When replacing the silica gel, use a vacuum cleaner to suck out the silica gel filled in the glass cover and replace the silica gel.

[0009] Furthermore, when filling the silica gel, the silica gel in the bottom layer can be filled in a silica gel box with a difference from the diameter of the glass cover greater than 1 silica gel particle diameter and less than 2 silica gel particle diameters, and the space of the glass cover above the silica gel box is filled with silica gel.

[0010] Furthermore, the specific method for replacing the silica gel is as follows: For the blue non-humidified silica gel, suck it out with a vacuum cleaner and take out the silica gel box at the bottom of the glass cover;

[0011] Replace the humidified and turned red silica gel in the taken-out silica gel box and put it back at the bottom of the glass cover, and refill the blue non-humidified silica gel into the glass cover.

[0012] Furthermore, the silica gel replaced into the silica gel box is encapsulated with a vacuum sealer before entering the silica gel box.

[0013] Specifically, the vacuum cleaner includes:

[0014] A lower housing and an upper cover body, the top of the lower housing is fixedly connected to the bottom of the upper cover body;

[0015] A vacuum pump, the air inlet of the vacuum pump is connected to one end of a trachea, and the top of the upper cover body is connected to the other end of the trachea;

[0016] A limiting frame, the limiting frame is fixedly connected to the inner side wall of the lower housing, and the limiting frame has an inner ring portion coaxial with the lower housing;

[0017] A suction pipe, the bottom end of the lower housing has a discharge port, the suction pipe is located inside the discharge port, the top end of the suction pipe is located above the limiting frame, and is fixedly connected with a restricting member, the bottom end of the suction pipe extends out of the lower housing and is provided with an annular outer edge.

[0018] Optionally, the limiting frame includes:

[0019] An outer ring portion, the outer ring portion is threadedly connected to the inner side wall of the lower housing;

[0020] The outer ring portion and the inner ring portion are fixedly connected by a bracket, and a notch matching the restricting member is provided inside the inner ring portion.

[0021] Optionally, the lower housing is made of a transparent material.

[0022] Optionally, a thin diameter portion is provided at the bottom of the discharge port, and a bottom flange is fixedly connected to the bottom end of the thin diameter portion.

[0023] Optionally, an annular opening is provided inside the thin-diameter part, and a sealing ring is arranged inside the annular opening.

[0024] Optionally, an air hole is provided on the side of the thin-diameter part and below the annular opening.

[0025] The beneficial effects of the present invention are as follows: Compared with the prior art, when replacing the silica gel of the present invention, there is no need to disassemble the silica gel breather. Instead, a vacuum cleaner is used to directly suck the silica gel from inside the glass cover, ensuring the efficiency of replacing the silica gel; when replacing the silica gel, the vacuum cleaner is used to suck instead of disassembling the silica gel box inside the silica gel breather, and the silica gel box that requires high processing precision to ensure tight fit is directly discarded. Since the silica gel fills the entire glass cover during filling to form a tight fit, the cost is lower. The present invention takes into account the silica gel replacement efficiency, cost, and dehumidification effect at the same time. Description of the Drawings

[0031] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0032] Embodiment 1: A method of using a silica gel breather without disassembly, the method is as follows:

[0033] When filling the silica gel, the silica gel box is not used, and the silica gel is directly filled into the glass cover;

[0034] When replacing the silica gel, a vacuum cleaner is used to suck away the silica gel filled in the glass cover and replace the silica gel.

[0035] When replacing the silica gel of the present invention, there is no need to disassemble the silica gel breather. Instead, a vacuum cleaner is used to directly suck the silica gel from inside the glass cover, ensuring the efficiency of replacing the silica gel; when replacing the silica gel, the vacuum cleaner is used to suck instead of disassembling the silica gel box inside the silica gel breather, and the silica gel box that requires high processing precision to ensure tight fit is directly discarded. On the premise of ensuring convenient disassembly and not affecting the dehumidification effect, the cost is lower.

[0036] Since the air in the silica gel breather moves upward from the bottom of the silica gel breather, the silica gel at the bottom of the glass cover has the highest degree of moisture. If the unmoistened silica gel in the upper part and the moistened silica gel in the lower part are sucked away together by a vacuum cleaner without distinction when sucking the silica gel, the unmoistened silica gel in the upper part will not be usable and will be wasted. To solve this problem, further in this embodiment, when filling the silica gel, the silica gel in the bottom layer can be filled in a silica gel box with a difference from the diameter of the glass cover greater than 1 silica gel particle diameter and less than 2 silica gel particle diameters, and the space of the glass cover above the silica gel box is filled with silica gel.

[0037] When replacing the silica gel, the silica gel outside the silica gel box is directly sucked away by a vacuum cleaner. Due to the protection of the silica gel, the silica gel in the silica gel box will not be sucked away and mixed with the silica gel outside the silica gel box. Also, because the silica gel box is placed at the bottom of the glass cover, the moist air coming from the lower part of the breather first absorbs moisture through the silica gel in the silica gel box. After the air absorbs moisture through the silica gel in the silica gel box, the humidity of the air is greatly reduced, and the degree of moistening of the silica gel above the silica gel box will be greatly reduced. Therefore, this replacement method will not cause waste due to the mixing of moist and unmoist silica gel.

[0038] In addition, since the silica gel in the bottom layer can be filled in a silica gel box with a difference from the diameter of the glass cover greater than 1 silica gel particle diameter and less than 2 silica gel particle diameters, the silica gel particles can enter the gap between the silica gel box and the glass cover. The silica gel in the gap can absorb moisture from the air passing through it. At the same time, because the vacuum cleaner has a relatively large diameter, it cannot suck the moisture-affected particles in the gap, ensuring that the moisture-affected silica gel does not mix with the less moisture-affected silica gel and ensuring that the less moisture-affected silica gel can be reused. Also, because the difference between the diameter of the silica gel box and the diameter of the glass cover is greater than 1 silica gel particle diameter and less than 2 silica gel particle diameters, the silica gel box does not need to be precisely processed to ensure precise fit, and the cost is lower. The gap between the silica gel box and the glass cover is due to the fact that it is filled with silica gel inside and its upper part is also filled with silica gel, so it will not affect the moisture absorption effect of the silica gel breather.

[0039] Further, the specific method for replacing the silica gel is as follows: The blue non-moist silica gel is sucked away by a vacuum cleaner, and the silica gel box at the bottom of the glass cover is taken out; the red moistened silica gel in the taken-out silica gel box is replaced and then put back at the bottom of the glass cover, and the blue non-moist silica gel is refilled into the glass cover.

[0040] Separate the replacement of silica gel particles with different degrees of moisture, so that the non-moistened particles can be reused without being affected.

[0041] Further, the silica gel replaced into the silica gel box is packaged with a vacuum sealer before entering the silica gel box. This makes the silica gel not get moistened during transportation and can be opened quantitatively according to needs, avoiding waste caused by bulk loading.

[0042] Specifically, referring to Figures 2 - 5 , the vacuum cleaner includes: a lower housing 1, an upper cover 2, and a vacuum pump 3. The top of the lower housing 1 is fixedly connected to the bottom of the upper cover 2, forming a cavity between the lower housing 1 and the upper cover 2. The air inlet of the vacuum pump 3 is connected to one end of a trachea 4, and the top of the upper cover 2 is connected to the other end of the trachea 4. When the vacuum pump 3 operates, air in the cavity is extracted through the trachea 4, generating negative pressure in the cavity formed between the lower housing 1 and the upper cover 2.

[0043] By providing a suction tube that can move up and down, when sucking silica gel particles, its bottom end can always be at the uppermost layer of the silica gel particles. As the silica gel particles decrease, it slides downward under the action of gravity. Moreover, a limiting frame is provided to limit the lowest position of the suction tube. When the suction tube penetrates to the 2 / 3 position (the position of the limiting frame can be adjusted according to different models of silica gel breathers), it can no longer move downward, making it very convenient to extract silica gel particles.

[0044] It further includes: a limiting frame 5 and a suction tube 6. The limiting frame 5 is fixedly connected to the inner side wall of the lower housing 1 and has an inner ring portion 53 coaxial with the lower housing 1. The bottom end of the lower housing 1 has a discharge port. The suction tube 6 is located inside the discharge port. The top end of the suction tube 6 is above the limiting frame 5 and is fixedly connected with a limiting member 62. The limiting member 62 cooperates with the limiting frame 5 to be able to limit the lowest position of the suction tube 6. The bottom end of the suction tube 6 extends out of the lower housing 1 and is provided with an annular outer edge 61. By providing the annular outer edge 61, it can prevent the bottom end of the suction tube 6 from being inserted into the silica gel particles.

[0045] Referring to the appendix Figure 5 , specifically, the limiting frame 5 includes: an outer ring portion 51, a bracket 52, and an inner ring portion 53. The outer ring portion 51 is threadedly connected to the inner side wall of the lower housing 1. By rotating the outer ring portion 51, the overall height of the limiting frame 5 can be adjusted, that is, the height of the inner ring portion 53 can be adjusted.

[0046] The outer ring portion 51 and the inner ring portion 53 are fixedly connected by the bracket 52. Specifically, three groups of brackets 52 are used for connection. A notch 54 matching the limiting member 62 is provided inside the inner ring portion 53.

[0047] In this solution, both the limiting member 62 and the notch 54 are in the shape of a long strip. The user rotates the suction tube 6 to make the limiting member 62 completely correspond to the notch 54, and then the suction tube 6 can be pulled downward to the lowest end.

[0048] Preferably, the lower housing 1 is made of a transparent material, specifically a transparent acrylic sheet, which has a certain anti-impact performance, facilitating the user to observe the quantity of the internal silica gel particles; and facilitating the rotation and adjustment of the suction tube 6 to make the limiting member 62 completely correspond to the notch 54, making it very convenient to use.

[0049] Reference appendix Figures 3 - 4 In this embodiment, a reduced-diameter portion 7 is provided at the bottom of the discharge port. A bottom flange 11 is fixedly connected to the bottom end of the reduced-diameter portion 7. The bottom flange 11 corresponds to the flange structure at the top of the silica gel breather, which facilitates the installation of this device.

[0050] An annular opening 8 is formed inside the reduced-diameter portion 7, and a sealing ring 9 is arranged inside the annular opening 8, which can improve the sealing performance and form a cavity between the lower housing 1 and the upper cover 2 where only the suction pipe 6 allows air to enter, resulting in a better suction effect.

[0051] An air hole 10 is formed on the side of the reduced-diameter portion 7 and below the annular opening 8. After the bottom flange 11 is connected to the flange structure at the top of the silica gel breather, the inside of the silica gel breather is in a relatively sealed state. The design of this air hole 10 facilitates the direct entry of external air into the silica gel breather.

[0052] Working principle: When in use, it is necessary to rotate and adjust the position of the limiting frame 5 according to the usage situation so that the bottom end of the suction pipe 6 just reaches the requirement. Connect the bottom flange 11 to the flange structure at the top of the silica gel breather. At this time, the silica gel particles inside the silica gel breather will push the suction pipe 6 upward, making the bottom end of the suction pipe 6 located at the top layer of the silica gel particles. Start the vacuum pump 3 to work, and a negative pressure is generated inside the cavity formed between the lower housing 1 and the upper cover 2, so that the bottom end of the suction pipe 6 has suction force to suck the silica gel particles into the lower housing 1. As the silica gel particles are sucked, the top layer of the silica gel particles inside the silica gel breather descends, and the suction pipe 6 also gradually moves downward until it reaches the lower limit position, that is, the suction of the silica gel particles in one breather is completed; repeat the operation like this to complete the suction of the silica gel particles inside multiple silica gel breathers. When the number of silica gel particles in the cavity formed between the lower housing 1 and the upper cover 2 reaches a certain amount, rotate the suction pipe 6 to make the limiting member 62 correspond to the notch 54, and pull the suction pipe 6 downward so that the top end of the suction pipe 6 is located at the discharge port position of the lower housing 1, and the silica gel particles inside the cavity can be poured out, which is very convenient to use.

It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope of the present invention.
