Description

Technical Field

[0001] The invention relates to the technical field of silica gel drying, and in particular to a drying system and a drying method for kitchenware silica gel. Background Art

[0002] Kitchenware is a general term for kitchen tools, such as pot covers, which are common kitchenware. At present, in order to improve the heat insulation, insulation and sealing properties of kitchenware, most kitchenware will be combined with silicone, and now silicone kitchenware is gradually standing out from the market.

[0003] Taking the pot lid as an example, the silicone installation position of the silicone pot lid is generally the edge of the pot lid. From then on, when in use, it can improve the sealing performance with the pot body and improve the cooking efficiency. However, since kitchen utensils are closely related to people's daily life, the production of silicone requires more caution than traditional silicone.

[0004] For example, in the production process and equipment of kitchen silicone utensils disclosed in the authorization announcement number CN112339188B, after the kitchen silicone is vulcanized, it needs to be sent to an oven for baking to volatilize the harmful substances in the silicone to ensure the qualified rate of silicone kitchen utensils. However, today's ovens mostly use heater-type ovens when baking silicone. Therefore, each oven is equipped with an independent heater, which has the disadvantage of excessive energy consumption.

[0005] Secondly, during baking, the silica gel is mostly loosely stacked, so it is easy to deform during the baking process; at the same time, due to factors such as the contact between the silica gels and the different distances between the silica gels and the heat source, the silica gel is dried unevenly, so the drying effect is not ideal.

[0006] Therefore, improvements are needed. Summary of the invention

[0058] In addition, the present invention also provides a drying method, which uses the above-mentioned drying system and includes the following steps:

[0059] S1: The trimmed silicone sleeve is placed on the limit ear of the filter and is stretched open by the filter. Then one end of the silicone clamp is inserted into the drying container and fixed on the machine body to complete the loading.

[0060] S2: Start the gas booster pump and heat exchanger to send hot air into the drive chamber.

[0062] In step S3, the hot air in the heat preservation chamber can enter the driving chamber of another dryer through the compensation pipe.

[0063] Preferably, step S3 also includes a method for using the dryer, and the method for using the dryer includes:

[0064] S-1: When the hot air flows in the driving chamber, the hot air passes through the driving impeller and controls the rotation of the second pulley;

[0068] Wherein, in step S-3 and / or step S-4, when hot air is introduced into the drying chamber through the air intake structure, the exhaust gas in the drying chamber is simultaneously discharged from the drying chamber through the exhaust chamber to balance the air pressure in the drying chamber.

[0069] The present invention has at least the following beneficial effects:

[0070] 1. The drying system of the present invention uses hot air drying to dry silica gel. The hot air is mainly generated by recovering waste heat from industrial activities through a heat exchanger, thereby improving energy utilization and achieving the purpose of energy saving.

[0071] 1.1 The hot air in the heat preservation chamber of the dryer of the present invention can be circulated through the compensation pipe and enter the next dryer for use, thereby further improving the utilization rate of the hot air.

[0072] 2. In order to avoid serious heat loss during silica gel drying, the hot air of the present invention is not directly sent into the drying chamber to dry the silica gel, but is mainly sent into the heat preservation chamber for storage, the purpose of which is to provide heat preservation for the drying chamber and prevent heat loss. At the same time, when the air intake structure is evacuated, the hot air in the heat preservation chamber can be timely extracted into the drying chamber to dry the silica gel. In more detail:

[0073] 2.1 The drying method of the dryer of the present invention is a combination of "external insulation" and "intermittent introduction of gas into the interior", wherein "external insulation" means that hot air is sent into the insulation chamber to insulate the drying container to prevent the hot air from being lost to the outside during drying; "intermittent introduction of gas into the interior" means that the hot air in the insulation chamber of the present invention is intermittently introduced into the drying container to dry the silica gel.

[0074] The present invention can isolate the waste gas generated by drying in the drying container from the hot air in the insulation chamber in a combined manner. Therefore, the waste gas generated will not be mixed with the hot air in the insulation chamber. Therefore, it can be continuously ensured that the hot air in the insulation chamber is not "contaminated" and can be extracted and used by each drying container.

[0075] 3. In order to further improve the drying effect of silica gel, the present invention arranges a drainage module in the drying container. Under the trend of the drainage module, the airflow entering the drying container from the air intake structure generates a first airflow and a second airflow. The first airflow is ejected from the one-way air nozzle and flows directly to the one-way air intake valve on the exhaust shaft, so that the silica gel can be dried quickly; when the second airflow is ejected from the one-way air nozzle, it is guided by the drainage module to flow circumferentially, and the circumferentially flowing airflow surrounds the filter and comprehensively dries the silica gel.

[0076] 3.1 During the flow of the first airflow and the second airflow, the filter is controlled to rotate by the drainage module, so that the silica gel in the drying container rotates, and the drying effect of the silica gel can be further ensured during the rotation process.

[0077] 4. In order to avoid damaging the silica gel, the present invention performs synchronous exhaustion by the exhaust shaft while the air intake structure takes in air, thereby ensuring that the air pressure in the drying container is stable, thereby avoiding high pressure from damaging the silica gel.

[0078] In addition, other advantages of the present invention will be demonstrated in the embodiment part of the present invention, thereby making the beneficial effects of the present invention more prominent and significant. BRIEF DESCRIPTION OF THE DRAWINGS

[0133] like Figure 3-4 As shown, in this embodiment, the air intake structure includes:

[0134] An intake piston reciprocates in the intake chamber;

[0135] A driving rod is connected between the intake piston and the piston block.

[0136] In this embodiment, the air inlet cavity includes:

[0137] The first chambers 41 are spaced apart in the container body 350 and are located between the corresponding one-way air inlet nozzles 352 and one-way air jet nozzles 353;

[0138] The second chamber 42 is connected between adjacent first chambers 41;

[0139] Among them, the cross-sectional diameter of the first chamber 41 is larger than the cross-sectional diameter of the second chamber 42, and the intake piston is composed of a plurality of piston bodies 41a movable in the first chamber 41 and a driving body 42a connected between adjacent piston bodies 41a and adapted to the second chamber 42, and a sealing ring 42b is provided in the second chamber 42.

[0140] In this embodiment, the one-way air jet nozzle, the one-way air inlet nozzle, the one-way air inlet valve and the one-way exhaust valve are all one-way valves.

[0141] refer to Figure 2-8 The principle and advantage of this embodiment are that, in this embodiment, the silicone used for the edge of the pot cover is used as an example:

[0142] 1. Installation of silicone: The cover is driven by a hydraulic cylinder to move away from the machine body, and the silicone sleeve is placed on the filter and fixed to the limiting ears of the filter. The silicone has a slot 54b that cooperates with the edge of the pot cover and can cooperate with the limiting ears to complete the installation of the silicone.

[0143] 2. Send into the drying chamber: After the silica gel is installed, the hydraulic cylinder drives the cover plate to move closer to the machine body and cooperate with the drying container to complete the loading.

[0144] 3. Drying: During drying, hot air enters the driving chamber from the air inlet, and enters the heat preservation chamber after passing through each driving impeller to keep the drying container warm;

[0145] After the hot air passes through the driving impeller, the driving impeller controls the rotation of the exhaust shaft through the cooperation of the first pulley and the second pulley. When the exhaust shaft rotates, the worm in the second chamber of the equipment chamber is controlled to rotate synchronously (due to the limiting ribs and limiting grooves on the matching surfaces of the exhaust shaft and the axial chamber, the exhaust shaft can drive the worm to rotate, and at the same time, the exhaust shaft and the worm can move axially relative to each other). When the worm rotates, the cam is driven to rotate through the worm wheel matched with it, and the rotation of the cam can cooperate with the return spring to control the piston block to move back and forth in the equipment chamber;

[0146] When the piston block moves back and forth, the air intake piston is controlled by the driving rod to move back and forth in the air intake chamber, that is, the piston body moves back and forth in the first chamber. When the piston body moves back and forth, the first chamber sucks hot air from the heat preservation chamber through the one-way air intake nozzle, and sends the hot air into the drying container through the one-way air nozzle, thereby completing the air intake;

[0147] When the piston block moves back and forth, the first chamber extracts the waste gas in the drying container through the exhaust chamber in the exhaust shaft and the one-way air inlet valve, and discharges the waste gas through the one-way exhaust valve on the transmission housing, thereby realizing timely discharge of the waste gas generated during the drying process of the silica gel;

[0148] When the piston block moves back and forth, the second mounting plate is driven to move back and forth in the drying container through the linkage rod, and the first mounting plate is driven to rotate clockwise or counterclockwise through the cooperation of the screw rod and the driven nut on one of the drainage shafts and the meshing driven gear and the control gear, thereby driving the filter screen installed with silica gel to start rotating clockwise or counterclockwise, thereby improving the uniformity of drying the silica gel.

[0149] It should be noted that when the hot air enters the drying container from the one-way air nozzle, it can be controlled and guided by the movable drainage shaft. When the drainage shaft is controlled to move back and forth by the second mounting plate, the drainage surface of the drainage shaft can receive the hot air or the through-hole on the drainage shaft can receive the hot air. When the drainage surface receives the hot air, the hot air is guided to move circumferentially around the silica gel and then flow toward the exhaust shaft. When the through-hole receives the hot air, the hot air directly passes through the drainage shaft and flows radially directly toward the exhaust shaft. This embodiment further improves the drying uniformity of the silica gel through two forms of airflow.

[0150] Secondly, in order to ensure the balance of air pressure in the drying container, while the one-way air nozzle is intake air into the drying container, the one-way air intake valve on the exhaust shaft is also exhausting air synchronously (extracting the gas in the drying container), thereby ensuring the balance of air pressure in the drying container and avoiding pressure imbalance in the drying container due to uncoordinated intake and exhaust, which may cause damage to the silica gel.

[0151] Third, when the air flow enters the drying container, the exhaust shaft also moves back and forth with the piston block. The movement of the exhaust shaft can change the position of the one-way air intake valve, thereby changing the relative position between the one-way air intake valve and the one-way air nozzle, thereby changing the moving path of the air flow in the drying container, which can further improve the uniformity of drying.
