Description

Technical Field

[0001] This utility model relates to the technical field of ethylene adsorption, and in particular to a renewable and recyclable ethylene adsorption device. Background Technology

[0002] The main function of ethylene adsorption is to inhibit the ripening and senescence process of fruits and vegetables. Ethylene is a plant hormone that plays a crucial role in the ripening process of fruits and vegetables, but it can also lead to premature ripening and a decline in quality. Therefore, ethylene adsorption is necessary during transportation to reduce the risk of damage and spoilage to fruits and vegetables. Existing technology publication number CN211753688U proposes a closed-space ethylene adsorption device, including an ethylene adsorption enclosed protective box, an ethylene adsorption device, an ethylene feed detection and diversion device, an ethylene shedding slide chamber, a shedding ethylene collection device, a sealed observation door, a miscellaneous gas discharge component, and a vacuum suction device. However, it is bulky, inconvenient for use during transportation, and cannot be self-regenerated, making its use rather inconvenient. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a regenerable and recyclable ethylene adsorption device that can effectively remove ethylene generated during storage, significantly reduce the risk of damage and spoilage to fruits and vegetables, and can be regenerated to restore its adsorption capacity.

[0004] This utility model discloses a recyclable ethylene adsorption device, comprising an adsorption box, an inlet pipe, an outlet pipe, an axial flow fan, an adsorption component, a filter component, and a regeneration component. The adsorption box is connected to the inlet pipe on its left end and the outlet pipe on its right end. An axial flow fan is installed inside the outlet pipe. The adsorption component is installed inside the adsorption box. Filter components are installed at the outer ends of the inlet and outlet pipes. The regeneration component is installed inside the outlet pipe. In use, the adsorption box is placed in a conveyor box, and the axial flow fan is activated to allow gas to enter the adsorption box through the inlet pipe. The adsorption component adsorbs ethylene from the gas, and the adsorbed gas is discharged again through the outlet pipe. This effectively removes ethylene generated during storage, significantly reducing the risk of damage and spoilage to fruits and vegetables. The filter component filters the inlet and outlet pipes to prevent impurities from entering. The regeneration component regenerates the adsorption component, restoring its adsorption capacity.

[0005] Preferably, the adsorption component includes an adsorption frame, two sets of limiting blocks, a molecular sieve adsorbent, and a sealing cover. The top of the adsorption box has an installation groove, and the limiting blocks are symmetrically installed at both ends of the installation groove. The front and rear ends of the adsorption frame have limiting slots that match the limiting blocks. The molecular sieve adsorbent is installed inside the adsorption frame, and the sealing cover is sealed and installed at the top of the adsorption box. After the gas enters through the inlet pipe, it passes through the molecular sieve adsorbent, which adsorbs and removes ethylene from the gas. The sealing cover can be removed and the adsorption frame can be pulled out from the installation groove, which facilitates the maintenance of the molecular sieve adsorbent after long-term use.

[0006] Preferably, the filter component includes two fixing rings, two filter screens, and two locking screws. Positioning grooves are provided at the ends of the inlet and outlet pipes. The fixing rings are fitted onto the outer ends of the inlet and outlet pipes, and positioning rings are provided on the inner wall of the fixing rings. The filter screens are installed on the fixing rings, and locking screws are screwed onto the outer wall of the fixing rings. By fitting the fixing rings onto the ends of the inlet and outlet pipes, the positioning rings of the fixing rings enter the positioning grooves. The fixing rings block and filter impurities from entering the inlet and outlet pipes, preventing them from affecting the adsorption and filtration effect.

[0007] Preferably, the regeneration component includes a heating tube, a controller, an air pump, an annular tube, and multiple purge heads. The heating tube is located on the inner wall of the inlet pipe to the right of the molecular sieve adsorbent. The annular tube is installed on the inner wall of the inlet pipe to the right of the heating tube. The air pump is installed on the rear wall of the adsorption chamber, and its output end is connected to the annular tube. Multiple purge heads are installed on the annular tube, and the controller is installed at the top of the inlet pipe. After use, the air pump is started to supply air into the annular tube, which is then output through the multiple purge heads. The heating tube is started to heat the air, which purges the molecular sieve adsorbent, regenerating it and restoring its adsorption capacity.

[0008] Preferably, it also includes a handle, two connectors and two sets of support feet. The two connectors are installed at the front and rear ends of the adsorption box, and the lower part of the handle is rotatably installed on the connectors. Support feet are symmetrically installed at the bottom of the air inlet pipe and the air outlet pipe. The support feet support the bottom of the equipment to ensure stability during use, and the handle makes it easy to hold and carry the equipment, improving portability during use.

[0009] Preferably, it also includes multiple guide vanes and a protective cover. The multiple guide vanes are axially installed on the inner wall of the intake pipe, and the protective cover is rotatably installed on the rear side wall of the controller. The guide vanes can guide the airflow, and the protective cover can cover the top of the controller to protect it.

[0010] Preferably, the heating tube is spiral-shaped; the spiral shape of the heating tube can ensure the contact area with the molecular sieve adsorbent and ensure the regeneration effect.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the adsorption box is placed in the conveying box, and the axial flow fan is started to allow the gas to enter the adsorption box through the air inlet pipe. The adsorption component adsorbs the ethylene in the gas, and the adsorbed gas is discharged again through the air outlet pipe. This can effectively remove the ethylene generated during storage, significantly reducing the risk of damage and rot of fruits and vegetables. The filter component can filter the air inlet and air outlet pipes to prevent the entry of impurities. The regeneration component can regenerate the adsorption component and restore its adsorption capacity. Attached Figure Description

[0020] Start the axial flow fan 4 to allow gas to enter the adsorption box 1 through the inlet pipe 2. After entering through the inlet pipe 2, the gas passes through the molecular sieve adsorbent 8, which adsorbs and removes ethylene from the gas. Remove the sealing cover 9 and pull the adsorption frame 6 to remove it from the mounting slot, facilitating maintenance of the molecular sieve adsorbent 8 after prolonged use. Fit the fixing ring 10 onto the ends of the inlet pipe 2 and the outlet pipe 3, ensuring the positioning ring of the fixing ring 10 enters the positioning groove. The fixing ring 10 blocks and filters the inlet pipe 2 and the outlet pipe 3, preventing impurities from entering and affecting the adsorption and filtration effect. After use, start... Air pump 16 supplies air into annular tube 17 and outputs it through multiple purge heads 18. Heating tube 13 is activated to heat the air and purge the molecular sieve adsorbent 8, regenerating it through heating and restoring its adsorption capacity. The spiral heating tube 13 ensures the contact area with the molecular sieve adsorbent 8, guaranteeing the regeneration effect. Support feet 21 support the bottom of the equipment to ensure stability during use. The handle 19 makes it easy to hold and carry the equipment, improving portability during use.

Starting the axial flow fan 4 allows gas to enter the adsorption box 1 through the inlet pipe 2. The guide plate 5 guides the airflow. After entering through the inlet pipe 2, the gas passes through the molecular sieve adsorbent 8, which adsorbs and removes ethylene from the gas. Removing the sealing cover 9 and pulling the adsorption frame 6 allows it to be taken out of the mounting slot for easy cleaning after prolonged use.
