Description

Technical Field

[0001] This invention relates to the field of shelving technology, and more particularly to a multifunctional shelving unit. Background Technology

[0002] In laboratories, warehouses, and other similar settings, shelves are often used to store moisture-sensitive materials (such as medicines, reagents, and precision electronic components). To maintain a dry environment, existing technologies typically place bags or boxes of desiccants in the corners or shelves of the shelves, such as a filing cabinet (CN216166115U) and a multi-functional wall-mounted shelf (CN122250756A). However, this static placement method has significant limitations:

[0003] First, the effective radius of desiccants is limited. When the material is far from the desiccant, moisture in the local space cannot be absorbed in time, resulting in uneven dehumidification. At the same time, the water absorption capacity of desiccants decreases non-linearly with the increase of water absorption, and existing solutions rely on manual periodic replacement, which leads to delayed replacement and a sharp drop in dehumidification efficiency.

[0004] Secondly, the regeneration and recycling of desiccants are difficult. Although physical adsorption desiccants such as silica gel can be reused through heating dehumidification, existing shelves lack integrated circulating drying systems.

[0005] Secondly, when materials are frequently accessed and the door needs to be opened and closed, high-humidity air from outside will rush in instantly, causing a sudden increase in humidity inside the cabinet. Existing passive dehumidification modes cannot respond quickly to such instantaneous high humidity loads, which can easily cause materials to become damp. Summary of the Invention

[0006] To overcome the shortcomings mentioned in the background art, this invention provides: a multifunctional storage rack, including a mounting frame; multiple storage panels for placing materials are provided in the mounting frame; the storage panels are hollow structures, and several through holes are opened on the top plate of the storage panels; it also includes a desiccant circulation system; the desiccant circulation system includes a storage box; the storage box is fixedly connected to the top of the mounting frame; a first feeding pipe is connected to one side of the storage panel, and the first feeding pipe is connected to the storage box; a discharge pipe is connected to the other side of the storage panel; a return pipe is installed and fixedly connected to the side of the mounting frame, the top of the return pipe is connected to the storage box through a pipe, and the bottom of the return pipe is connected to the discharge pipe.

[0007] Furthermore, a motor is installed at the bottom of the return pipe, and a auger is fixed to the rotating part of the motor. The auger rotates to transport the desiccant in the return pipe upward to the storage box.

[0008] Furthermore, it also includes a long-distance drying system; the long-distance drying system includes a hot air duct and a filter screen; a hot air duct is connected to the top of the return pipe; and a filter screen for exhaust is fixed to the bottom of the return pipe.

[0009] Furthermore, it also includes vertical partitions, with vertical partitions installed on the shelf.

[0010] Furthermore, the vertical partition is designed as a hollow structure, and several through holes are provided on the left and right side panels of the vertical partition. The bottom of the vertical partition is connected to the storage plate. It also includes a second feeding pipe. The upper part of the vertical partition is connected to the second feeding pipe, and one end of the second feeding pipe is connected to the storage box.

[0011] Furthermore, it also includes an electric valve installed on the second feeding pipe; it also includes a control system that opens the electric valve when the mounting frame door is opened.

[0012] Furthermore, it also includes an electric push rod and a pusher; an electric push rod is fixedly connected to the inside of the shelf, and a pusher is fixedly connected to the telescopic part of the electric push rod. The electric push rod drives the pusher to move left and right inside the shelf, thereby transferring the desiccant in the shelf to the discharge pipe.

[0013] Furthermore, the pusher has two elastic push plates arranged in a V-shape; when the two elastic push plates move to the left, the two elastic push plates move closer to each other, and when the two elastic push plates move to the right, the two elastic push plates move further apart.

[0014] Furthermore, after the electric push rod telescopic part extends, the pusher is located below the vertical partition, blocking the desiccant in the vertical partition.

[0015] Furthermore, a humidity sensor is installed in the mounting frame to detect the humidity in the mounting frame in real time.

[0016] Compared with existing technologies, this invention has the following advantages: By constructing a three-dimensional circulation structure of a hollow storage plate, vertical partitions, and a return pipe, this invention not only achieves close contact between the desiccant and the material but also breaks the limitations of traditional static placement of desiccants, significantly improving dehumidification efficiency. Specifically, by utilizing a long-distance drying system with auger lifting and reverse hot air, the desiccant is dried and reused within the confined space of the return pipe, solving the problem of precipitous performance drop caused by desiccant moisture absorption decay. For the instantaneous high humidity condition upon opening the door, the vertical partitions are used as "emergency drying columns," with instantaneous material replenishment controlled by an electric valve, achieving rapid counter-moisture absorption treatment. Furthermore, by introducing a pusher with a V-shaped elastic pusher plate, the flow stagnation of the desiccant is forcibly broken, ensuring uniform flow; and by utilizing the sealing and pushing action of the pusher's rightward movement at the bottom of the vertical partitions, a smooth switch of the desiccant from high-humidity emergency mode to low-humidity normal mode is cleverly achieved, requiring no additional power to gradually clean the remaining material within the vertical partitions as the moisture content decreases.

Detailed Implementation

[0024] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0025] In laboratories, warehouses, and other similar settings, shelves are often used to store moisture-sensitive materials (such as medicines, reagents, and precision electronic components). To maintain a dry environment, existing technologies typically place bags or boxes of desiccants in the corners or shelves of the shelves, such as a filing cabinet (CN216166115U) and a multi-functional wall-mounted shelf (CN122250756A). However, this static placement method has significant limitations:

[0026] First, the effective radius of desiccants is limited. When the material is far from the desiccant, moisture in the local space cannot be absorbed in time, resulting in uneven dehumidification. At the same time, the water absorption capacity of desiccants decreases non-linearly with the increase of water absorption, and existing solutions rely on manual periodic replacement, which leads to delayed replacement and a sharp drop in dehumidification efficiency.

[0027] Secondly, the regeneration and recycling of desiccants are difficult. Although physical adsorption desiccants such as silica gel can be reused through heating dehumidification, existing shelves lack integrated circulating drying systems.

[0028] Secondly, when materials are frequently accessed and the door needs to be opened and closed, high-humidity air from outside will rush in instantly, causing a sudden increase in humidity inside the cabinet. Existing passive dehumidification modes cannot respond quickly to such instantaneous high humidity loads, which can easily cause materials to become damp.

[0029] In response to this, the present invention is proposed.

[0030] Example 1: As Figures 1-6 As shown, the present invention provides: a multifunctional storage rack, including a mounting frame 1; the mounting frame 1 is provided with a plurality of storage boards 2 for placing materials, wherein the materials belong to the category of materials that need to be dried and stored; wherein the storage boards 2 are configured as hollow structures, and the top plate of the storage boards 2 is provided with a plurality of through holes.

[0031] It also includes a desiccant circulation system; the desiccant circulation system includes a storage tank 31, a first feeding pipe 32, a discharge pipe 33, and a return pipe 34; the storage tank 31 is fixedly connected to the top of the mounting frame 1; the first feeding pipe 32 is connected to one side of the shelf 2, and the first feeding pipe 32 is connected to the storage tank 31, and the storage tank 31 feeds desiccant into the shelf 2 through the first feeding pipe 32; the discharge pipe 33 is connected to the other side of the shelf 2;

[0032] A return pipe 34 is fixedly installed on the side of the mounting frame 1. The top of the return pipe 34 is connected to the storage box 31 through a pipe, and the bottom of the return pipe 34 is connected to the discharge pipe 33. The desiccant in the shelf 2 is transferred to the bottom of the return pipe 34 through the discharge pipe 33.

[0033] The desiccant used is a granular desiccant, such as silica gel desiccant.

[0034] Furthermore, a motor 35 is installed at the bottom of the return pipe 34, and a auger is fixed to the rotating part of the motor 35. The desiccant in the return pipe 34 is conveyed upward to the storage box 31 by the rotation of the auger.

[0035] Furthermore, it also includes a long-distance drying system; the long-distance drying system includes a hot air duct 41 and a filter screen 42; the hot air duct 41 is connected to the top of the return pipe 34; and the filter screen 42 for exhaust is fixed to the bottom of the return pipe 34.

[0036] Furthermore, it also includes vertical partitions 5, which are provided on the shelf 2 to separate materials.

[0037] Furthermore, the vertical partition 5 is designed as a hollow structure, and several through holes are provided on the left and right side panels of the vertical partition 5. The bottom of the vertical partition 5 is connected to the shelf 2.

[0038] It also includes a second feeding pipe 61; the upper side of the vertical partition 5 is connected to the second feeding pipe 61, one end of the second feeding pipe 61 is connected to the storage box 31, and the storage box 31 feeds desiccant into the vertical partition 5 through the second feeding pipe 61.

[0039] Furthermore, it also includes an electric valve 62, which is installed on the second feeding pipe 61; it also includes a control system, which opens the electric valve 62 when the switch door 1a of the mounting frame 1 is opened, and closes it when the switch door 1a of the mounting frame 1 is closed.

[0040] Furthermore, it also includes an electric push rod 71 and a pusher 72; the electric push rod 71 is fixedly connected to the inside of the shelf 2, and the pusher 72 is fixedly connected to the telescopic part of the electric push rod 71. The electric push rod 71 drives the pusher 72 to move left and right inside the shelf 2, thereby transferring the desiccant in the shelf 2 to the discharge pipe 33.

[0041] Furthermore, the pusher 72 has two V-shaped elastic push plates; to Figure 5 As shown in the angle, when the two elastic push plates move to the left, they move closer together; when the two elastic push plates move to the right, they move further apart.

[0042] Furthermore, after the telescopic part of the electric push rod 71 extends, the pusher 72 is located below the vertical partition 5, blocking the desiccant in the vertical partition 5 and preventing it from moving down.

[0043] Furthermore, a humidity sensor is installed in the mounting frame 1 to detect the humidity in the mounting frame 1 in real time.

[0044] Based on the above problems and structure, the working principle of this invention is as follows:

[0045] like Figures 1-2 As shown, the materials that need to be dried and stored are placed on the shelf 2. The shelf 2 is a hollow structure and is filled with desiccant, so that the desiccant can absorb the moisture around the materials through the through holes in the top plate of the shelf 2. This overcomes the problem in the prior art that the desiccant is only placed on one side or in one place of the shelf, and the desiccant's ability to absorb moisture around the materials is insufficient when the materials are far away from the desiccant.

[0046] Furthermore, existing technologies often address the issue of desiccant's water absorption capacity decreasing with the amount of water absorbed by manually removing the desiccant, which leads to a precipitous drop in dehumidification efficiency due to delayed replacement. To address this, the present invention incorporates a desiccant circulation system and a long-distance drying system that can dry and reuse the desiccant in real time, ensuring that the desiccant maintains a strong water absorption and dehumidification capacity at all times.

[0047] The specific desiccant circulation operation is as follows: the desiccant in the storage tank 31 flows downward through the first feeding pipe 32 into the storage plate 2, and then the desiccant in the storage plate 2 flows downward through the discharge pipe 33 to the return pipe 34. Then the desiccant flows upward through the return pipe 34 back to the storage tank 31. In this way, the desiccant is circulated in the storage plate 2, and the dried desiccant can be continuously placed in the storage plate 2 to dehumidify the material on the storage plate 2. The problem of the desiccant's water absorption capacity decreasing with the amount of water absorbed is overcome by continuously replenishing new desiccant.

[0048] The specific long-distance drying operation of the desiccant is as follows: the desiccant that has absorbed water in the placement plate 2 enters the bottom of the return pipe 34 through the discharge pipe 33, and then is slowly transferred to the top of the return pipe 34 by the auger driven by the motor 35. During this process, hot air is sent into the hot air pipe 41. The hot air acts on the desiccant in the long-distance return pipe 34, flowing from top to bottom and acting on the desiccant in the return pipe 34. Finally, it flows out from the filter screen 42. At the same time, the desiccant is transferred from bottom to top. In this way, the hot air dries the desiccant over a long distance and carries the water vapor in the desiccant out through the filter screen 42, so that the desiccant that has absorbed water can be recycled.

[0049] Of course, the present invention is also provided with vertical partitions 5, which are used to separate materials when they need to be stored separately according to their type.

[0050] Furthermore, regarding the problem that opening the switch door 1a during material handling causes a sudden increase in the amount of moisture in the mounting frame 1, the present invention can control the electric valve 62 to open when the control system detects that the switch door 1a is open. At this time, the desiccant in the storage box 31 can be transferred to the vertical partition 5 through the second feeding pipe 61, so that the vertical partition 5 is filled with desiccant. In this way, by increasing the amount of desiccant in the mounting frame 1, the sudden increase in the amount of moisture is offset and absorbed, ensuring that the material is not affected by moisture after the switch door 1a is opened.

[0051] Furthermore, to improve the uniformity and flow efficiency of the desiccant in the storage plate 2, allowing the absorbent desiccant to be discharged promptly and replenished with fresh desiccant, this invention includes an electric push rod 71 and a pushing member 72. When the desiccant needs to flow in the storage plate 2, the extension and retraction of the electric push rod 71 drives the pushing member 72 to move left and right. The pushing member 72 has two elastic push plates arranged in a V-shape. Figure 5 As shown in the angle, when the two elastic push plates move to the left, they are squeezed together by the desiccant and move closer to each other. When the two elastic push plates move to the right, they are squeezed apart by the desiccant and move away from each other. When the two elastic push plates open and move to the right, the desiccant can be pushed to the right. The front and rear length of the pusher 72 can cover the shelf 2. In this way, by moving the pusher 72 left and right, the desiccant can be evenly transferred from left to right in the shelf 2, overcoming the problem that the water-absorbing desiccant is not transferred in time.

[0052] Furthermore, considering that when the door 1a is closed, the amount of moisture in the mounting frame 1 will gradually decrease to a normal level; when the door 1a is closed, the electric valve 62 is closed, and the vertical partition 5 is filled with desiccant, and no new desiccant will be added to the vertical partition 5; in this invention, after the extension part of the electric push rod 71 extends, the pusher 72 is located below the vertical partition 5, which can block the desiccant in the vertical partition 5 and prevent it from moving down; and when the vertical partition 5 is filled with desiccant, each time the pusher 72 moves left and right, it will carry away a portion of the desiccant in the vertical partition 5. Thus, the left and right movement of the pusher 72 will gradually carry away the desiccant in the vertical partition 5 as the amount of moisture in the mounting frame 1 gradually decreases, leaving only desiccant flowing in the shelf 2 to cope with the normal level of moisture.

[0053] In summary, this invention, through the construction of a three-dimensional circulation structure consisting of a hollow storage plate 2, vertical partitions 5, and a return pipe 34, not only achieves close contact between the desiccant and the material but also breaks through the limitations of traditional static desiccant placement, significantly improving dehumidification efficiency. Specifically, by utilizing a long-distance drying system with auger lifting and reverse hot air, the desiccant is dried and reused within the confined space of the return pipe 34, solving the problem of a sharp drop in efficiency caused by desiccant moisture absorption degradation. For situations of instantaneous high humidity upon door opening, the vertical partition 5 serves as an "emergency drying column," with instantaneous replenishment controlled by an electric valve 62, achieving rapid counter-humidification treatment. In addition, by introducing a pusher 72 with a V-shaped elastic pusher plate, the flow stagnation problem of the desiccant is forcibly broken, ensuring the uniformity of flow; and by using the blocking and pushing action of the pusher 72 to the right to block and push the bottom of the vertical partition 5, the desiccant is smoothly switched from the high humidity emergency mode to the low humidity normal mode. The remaining material in the vertical partition 5 can be cleaned up gradually as the amount of water vapor decreases without the need for additional power.
