Description

Technical Field

[0001] The utility model relates to the technical field of silica gel production, in particular to a moisture absorption device for silica gel production. Background Art

[0002] The main process flow for color-changing silica gel is to select spherical raw material rubber, absorb moisture until saturated, then impregnate it with dye, and finally dry it to obtain color-changing silica gel. Currently, the moisture absorption process in the color-changing silica gel production process in the industry generally adopts the method of directly sprinkling water onto the silica gel covered with felt cloth to absorb moisture. Water droplets are manually sprayed with a water pipe according to the degree of wetness on the felt cloth. The main disadvantage of this process is that the manual water spraying is not timely and uniform, resulting in a slow moisture absorption rate of the silica gel. The internal structure of silica gel is porous. If the amount of water sprayed is too large, the silica gel absorbs water too quickly, causing internal stress to cause the surface to crack and break. This reduces the recovery rate of the silica gel, increases production costs, and has high labor costs. Summary of the Invention

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be noted that the following examples are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Similarly, the following examples are merely partial embodiments of the present invention and are not intended to be exhaustive. All other embodiments derived by persons of ordinary skill in the art without inventive effort are intended to fall within the scope of protection of the present invention.

[0042] See also Figure 1 and Figure 2 , this embodiment provides a silica gel particle 6 moisture absorption device, including a moisture absorption box 1, an atomizing component 2, a sensor component 3, a moisture absorption vehicle 5 and a centrifugal fan 4, the moisture absorption box 1 includes a first inlet, a first outlet and a first chamber, the first inlet and the first outlet are respectively connected to the first chamber, and the first inlet and the first outlet are arranged on opposite sides; the atomizing component 2 includes an atomizing port 22 and an atomizer 21, the atomizer 21 is connected to the atomizing port 22, and the atomizing port 22 is arranged in the first chamber; the sensor component 3 includes a plurality of first temperature sensors 31 and a plurality of first humidity sensors 32, and the plurality of first temperature sensors 31 are in a first preset The first chamber is provided with a plurality of first humidity sensors 32 arranged in a second preset manner. The sensor assembly 3 is used to detect the temperature and humidity in the first chamber. The sensor assembly 3 is linked with the atomizer 21. The desiccant vehicle 5 has a first carrying surface on which silica gel particles 6 are laid. The desiccant vehicle 5 enters the first chamber through a first inlet and moves out of the first chamber through a first outlet along a first moving direction a. The centrifugal fan 4 is connected to the first chamber. The centrifugal fan 4 is used to output airflow along a second moving direction b to drive air circulation in the first chamber. The second moving direction b is opposite to the first moving direction a.

[0043] In this embodiment, the desiccant device includes a movable desiccant vehicle 5 and an immovable desiccant box 1, wherein the desiccant box 1 is provided with an atomizing assembly 2, a sensing assembly 3, and a centrifugal fan 4. The desiccant box 1 can be understood as a smaller desiccant space. In the prior art, desiccant generally uses a pre-divided building room as a desiccant chamber, and uses an atomizer 21 and other equipment in the desiccant chamber to adjust the humidity in the room. Different from the prior art, the desiccant box 1 shown in this embodiment is a box structure, that is, it can be understood as a desiccant environment smaller than the existing building room. Unlike the desiccant chamber, the atomizer 21 in the atomizing assembly 2 can be set outside the desiccant box 1 and connected to the desiccant box 1 through a pipe. This can reduce the overall desiccant space and achieve lower-cost environmental humidity regulation. The desiccant box 1 can be built using boards or structures such as concrete.

[0044] For ease of presentation, the desiccant housing 1 is divided into a first chamber, a first outlet, and a first inlet. Both the first inlet and the first outlet are connected to the first chamber. A movable desiccant vehicle 5 can enter through the first inlet and exit through the first outlet, thereby absorbing the desiccant silica gel particles 6 in batches. It should be noted that the first inlet and the first outlet are located on opposite sides of the housing. This facilitates the sequential entry of multiple desiccant vehicles 5, preventing them from becoming congested on one side of the housing 1 and affecting the desiccant silica gel particles 6.

[0045] In this embodiment, the atomizing assembly 2 includes an atomizer 21 and an atomizing port 22. The atomizing port 22 is connected to the first chamber. The atomizer 21 can be a commercially available atomizer 21 and is connected to the atomizing port 22 via a pipeline. The atomizer 21 can be continuously replenished with water to continuously generate mist, and the mist is transported into the first chamber through the atomizing port 22 to maintain the humidity in the first chamber. Optionally, the humidity of the moisture absorption box 1 is controlled at 50-80% to facilitate moisture absorption by the silica gel particles 6 on the moisture absorption vehicle 5.

[0046] In this embodiment, a sensor component 3 is also provided. The sensor component 3 includes a first temperature sensor 31 and a first humidity sensor 32. Optionally, the first temperature sensor 31 and the first humidity sensor 32 can be integrated into one device. In this embodiment, multiple first temperature sensors 31 are distributed in the first chamber in a first preset manner. The first preset manner can be set according to actual needs. It is understood that the first temperature sensors 31 are evenly distributed in the first chamber to achieve the collection of temperatures in multiple areas in the first chamber, thereby improving the accuracy of the final temperature detection result. Similarly, multiple first humidity sensors 32 are distributed in the first chamber in a second preset manner. The second preset manner can be set according to actual needs. It is understood that the first humidity sensors 32 are evenly distributed in the first chamber to achieve the collection of humidity in multiple areas in the first chamber, thereby improving the accuracy of the final humidity detection result.

[0047] It is understandable that the number of the first temperature sensors 31 is at least two, and the number of the first humidity sensors 32 is at least two, so as to meet actual usage requirements.

[0048] Furthermore, the first temperature sensor 31, the first humidity sensor 32 and the signal of the atomizer 21 are interlocked. When the temperature and humidity in the first chamber do not meet the usage requirements, the user uses the specific temperature and humidity values as a reference to adjust the output power of the atomizer 21 to adjust the temperature and humidity in the first chamber. Similarly, when the humidity in the first chamber exceeds 80%, the atomizer 21 stops the atomization operation in time according to the signals of the first temperature sensor 31 and the first humidity sensor 32 to maintain the humidity in the first chamber.

[0049] In this embodiment, the moisture absorption vehicle 5 has a first supporting surface, preferably facing upward. A certain thickness of silica gel particles 6 are evenly spread on the first supporting surface to facilitate moisture absorption. For ease of description, the direction of movement of the moisture absorption vehicle 5 is referred to as the first moving direction a, which is the direction from the first inlet to the first outlet.

[0050] The centrifugal fan 4 can be disposed outside the moisture absorption housing 1 and connected to the first chamber via piping. The centrifugal fan 4 can promptly draw air from the first chamber through the high-speed rotation of its internal blades and then recirculate it into the first chamber, thereby achieving air circulation within the first chamber and promoting uniform flow of mist in the air, thereby improving the moisture absorption efficiency of the silica gel particles 6. In this embodiment, the direction of air flow caused by the centrifugal fan 4 is denoted as the second movement direction b, and the first movement direction a is opposite to the second movement direction b. This approach can increase the gas flow rate on the surface of the silica gel particles 6, thereby accelerating the moisture absorption efficiency of the silica gel particles 6.

[0051] The desiccant device shown in this embodiment allows for controllable moisture absorption temperature for the silica gel. Atomizer 21 provides uniform moisture replenishment, ensuring air humidity remains within the dew point. This results in efficient and uniform absorption of the silica gel particles 6, low breakage, and a low product sphericity. The desiccant device occupies a small footprint, and its unit volumetric desiccant capacity far exceeds that of traditional floor-mounted desiccant absorption methods. Compared to existing technologies, this embodiment eliminates the use of felt cloth for desiccant absorption, resulting in less labor-intensive, simpler, and more controllable operation. It also prevents the long-term use of felt cloth, which can harbor microorganisms and negatively impact product quality.

[0052] See also Figure 1In some embodiments, there are multiple atomization ports 22, and they are distributed above the first chamber along a third preset pattern; the atomization assembly 2 further includes a first flow guide main pipe 23 and multiple first flow guide branches 24, and the first flow guide main pipe 23 is connected to the atomizer 21; the multiple first flow guide branches 24 are respectively connected to the first flow guide main pipe 23, and each first flow guide branch 24 is provided with an atomization port 22.

[0053] In this embodiment, there are multiple atomization ports 22. The specific third preset mode can be set according to actual needs. The distribution basis of the third preset mode is to make the atomization ports 22 as evenly distributed as possible in the moisture absorption box 1. Optionally, the number of atomization ports 22 can be 4.

[0054] Furthermore, the atomization assembly 2 includes a first main flow guide pipe 23 and a plurality of first branch flow guide pipes 24. The first main flow guide pipe 23 is connected to the output end of the atomizer 21, and the mist generated by the atomizer 21 is evenly distributed within the first main flow guide pipe 23. Each first branch flow guide pipe 24 is independently connected to the first main flow guide pipe 23, and an atomization port 22 is provided at the other end of each first branch flow guide pipe 24. The mist flows through the first main flow guide pipe 23 into the plurality of first branch flow guide pipes 24, and then into the first chamber, thereby achieving even distribution of moisture within the first chamber.

[0055] In some embodiments, the atomizing assembly 2 further includes a water tank and a water pump, wherein the water tank is connected to the atomizer 21; the water pump is disposed at the connection between the water tank and the atomizer 21. This approach can achieve a continuous water supply to the atomizer 21 to meet actual usage needs.

[0056] In some embodiments, a first drainage groove 11 is further included. The first drainage groove 11 is arranged at the bottom of the hygroscopic box body 1 and distributed along the inner edge of the hygroscopic box body 1. A first water outlet is provided on the hygroscopic box body 1, and the first water outlet is connected to the first drainage groove 11.

[0057] In this embodiment, the first water outlet is arranged at the bottom of the moisture absorption box 1, and the first water outlet is connected to the first sewage drainage groove 11, so that the accumulated water on the inner wall of the first chamber can be discharged in time, reducing the liquid residue in the first chamber, thereby reducing the microbial content in the entire first chamber.

[0058] In some embodiments, the desiccant box 1 also includes a first opening and closing door and a second opening and closing door. The first opening and closing door is arranged at the first entrance. The first opening and closing door can be opened and closed relative to the first entrance to allow the desiccant vehicle 5 to enter. The first opening and closing door is air-tightly connected to the first entrance when the door is closed; the second opening and closing door is arranged at the first exit. The second opening and closing door can be opened and closed relative to the first exit to allow the desiccant vehicle 5 to exit. The second opening and closing door is air-tightly connected to the first exit when the door is closed.

[0059] In this embodiment, the structure, material and shape of the first opening and closing door and the second opening and closing door can be the same, the difference being that the first opening and closing door is arranged at the first entrance and the second opening and closing door is arranged at the second entrance. Taking the first opening and closing door as an example, the second opening and closing door can be understood with reference to the structure of the first opening and closing door. The first opening and closing door can be hinged to a side edge of the first entrance via a hinge. Furthermore, a sealing strip can be added to the peripheral edge of the first opening and closing door. The sealing strip can be made of silicone material. When the first opening and closing door is closed on the first entrance, the first opening and closing door can be airtightly connected to the edge of the first entrance, effectively isolating the external air from the air circulation inside the hygroscopic box 1, thereby avoiding leakage of internal moisture, helping to maintain the humidity inside the hygroscopic box 1, and reducing energy loss.

[0060] See also Figure 2 In some embodiments, the desiccant vehicle 5 further includes a vehicle body 52, on which a plurality of load-bearing partitions 53 are provided, each of which is provided with a first load-bearing surface, and the plurality of load-bearing partitions 53 are arranged at intervals in a vertical or horizontal direction, and a plurality of ventilation holes are provided on the first load-bearing surface, and the diameter of the ventilation holes is smaller than the diameter of the silica gel particles 6.

[0061] In this embodiment, the supporting partitions 53 are spaced vertically or horizontally, and the supporting partitions 53 are laid horizontally. This allows the silica gel particles 6 to be spread evenly on the supporting partitions 53 at a certain thickness. The first supporting surface is provided on the upper surface of the first supporting partition 53. In this embodiment, the first supporting surface is provided with multiple ventilation holes. The diameter of the ventilation holes is smaller than that of the silica gel particles 6, and the distribution of the ventilation holes can be customized according to actual needs. The provision of ventilation holes in this embodiment facilitates the vertical or horizontal infiltration of mist, thereby improving the moisture absorption efficiency of the silica gel particles 6 on the multiple supporting partitions 53 at the bottom.

[0062] See also Figure 2 In some embodiments, each load-bearing partition 53 is provided with a plurality of ventilation slots 54; the ventilation slots 54 on two adjacent load-bearing partitions 53 are staggered in the vertical or horizontal direction. Figure 2 As shown, mist can directly enter the area of the load-bearing partition 53 located in the next layer through the ventilation slots 54, thereby improving the moisture absorption efficiency of the silica gel particles 6 in the next layer. Preferably, the ventilation slots 54 of two adjacent load-bearing partitions 53 are staggered in the vertical or horizontal direction. This method allows mist to penetrate each load-bearing partition 53 at a relatively uniform rate, ensuring that the moisture absorption efficiency of the silica gel particles 6 on the entire vehicle body 52 is within the same or similar numerical range, meeting practical needs.

[0063] See also Figure 2In some embodiments, the load-bearing partition 53 is further provided with second drainage grooves 51, which are distributed along the circumference of the load-bearing partition 53. The moisture absorption vehicle 5 also includes a second main flow diversion pipe and multiple second branch flow diversion pipes. The second main flow diversion pipe is disposed on the vehicle body 52. Each second branch flow diversion pipe is connected to the second main flow diversion pipe, and each second branch flow diversion pipe is connected to a second drainage groove 51. This arrangement allows for the timely discharge of water droplets condensed from the mist remaining on the moisture absorption vehicle 5 when the silica gel particles 6 are saturated with moisture.

In this embodiment, the drive unit is arranged at the bottom of the vehicle body 52, and the drive unit can be an AGV mobile unit, so that the motion state of the dehumidification vehicle 5 can be automatically controlled, freeing up manpower. Furthermore, this embodiment is also provided with a control unit, which is electrically connected to the drive unit, the sensor component 3, the atomization component 2, and the centrifugal fan 4. Specifically, the control unit can be a single-chip microcomputer, a microcomputer chip, etc. The control unit can realize automatic control of the dehumidification device, thereby freeing up productivity and improving production efficiency.

[0065] The above embodiments have the following beneficial effects:

[0066] (1) The wet temperature of the silica gel is controllable, and the atomizer 21 is used to evenly replenish moisture to ensure that the air humidity is within the dew point, which is conducive to the quick and uniform moisture absorption efficiency of the silica gel particles on the moisture absorption vehicle in the moisture absorption box, low breakage rate, and low product sphericity rate.
