Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding machine technology, specifically to a feeding machine for deoxidizing agents. Background Technology
[0002] Oxygen scavengers, also known as deoxidizers or desiccants, are used in food, pharmaceuticals, and other products to prevent spoilage, deterioration, mold growth, and deodorization. They work by absorbing moisture released from food. For high-moisture foods, oxygen scavengers are typically sealed with the food, and oxygen absorption usually occurs in the presence of water. They often utilize the moisture evaporated from the food for the deoxygenation reaction. This type of oxygen scavenger helps maintain the nutritional value of the product and prevents quality loss. It can reduce the oxygen content inside the packaging to less than 0.1% and maintain that level. Therefore, in fields such as boiler deoxygenation, water treatment, and food processing, mechanical devices are needed to introduce oxygen scavengers into boilers or other equipment requiring deoxygenation.
[0003] Chinese patent document CN210088828U discloses a special deoxygenator feeder. By incorporating a horizontal pipe, a liquid outlet pipe, a connecting sleeve, a nozzle, a drive motor, a drive gear, and a driven gear, the deoxygenator is evenly sprayed into raw water, improving deoxygenation efficiency. The amount of deoxygenator is controlled by a measuring cylinder, a storage tank, a liquid inlet pipe, a connecting pipe, a feed control valve, and a feeding control valve, achieving precise feeding. A limit ring and a roller are incorporated to improve the stability of the connecting sleeve's rotation.
[0004] The existing technology has the following problems:
[0005] Current oxygen scavenger feeders do not have drying and screening functions. In actual use, the oxygen scavenger is stored in the tank for a long time. Before feeding, some of the oxygen scavenger in the tank will become damp or clump, which will affect its performance. Furthermore, the clumped oxygen scavenger will clog the feeder.

Detailed Implementation
[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0030] like Figures 1-8 As shown, a deoxidizer feeding machine includes a base plate 1. A screening box 3 and a storage box 2 are fixedly installed on the upper surface of the base plate 1, with the storage box 2 located to the right of the screening box 3. A screening assembly 6 is rotatably connected to the inner cavity of the screening box 3. A feeding pipe 5 is fixedly installed on the left side of the screening box 3, and a drying assembly 4 is fixedly installed on the right side of the screening box 3. A guide pipe 7 is fixedly installed on the upper left side of the storage box 2. A motor 8 is fixedly installed on the upper surface of the storage box 2. The output end of the motor 8 extends into the inner cavity of the storage box 2, where an auger 9 is fixedly installed. The lower end of the auger 9 is rotatably connected to the lower surface of the inner cavity of the storage box 2. Both the feeding pipe 5 and the guide pipe 7 are in the shape of a "7". The lower surface of the inner cavity of the screening box 3 is inclined to the lower left to allow the screened deoxidizer to flow smoothly into the feeding pipe 5. The screening assembly 6 includes a rotating shaft 611, the rear end of which is connected to the inner cavity of the screening box 3. The lower side of the cavity is rotatably connected, and the front end passes through the screening box 3. The second rotating shaft 611 is located on the outer side of the inner cavity of the screening box 3 and a screen frame 68 is fixedly installed. The front end of the second rotating shaft 611 passes through the screening box 3 and a connecting plate 66 is fixedly installed. A right-angle plate 61 is fixedly installed on the left front side of the screening box 3. A hinge seat 62 is fixedly installed on the front side of the right-angle plate 61. An electric push rod 63 is rotatably connected to the opposite side of the hinge seat 62. The output end of the electric push rod 63 is rotatably connected to a connecting plate 65. A collection box 610 is fixedly installed on the right side of the screening box 3 and is located below the drying assembly 4. The right end of the screen frame 68 extends into the inner cavity of the collection box 610. The drying assembly 4 includes a drying cylinder 41. The left side of the drying cylinder 41 is fixedly installed on the upper right side of the screening box 3. An electric heating tube 44 is sleeved on the outer side of the drying cylinder 41. The feed end of the drying cylinder 41 is located directly below the guide pipe 7.
[0031] In use, the feeding machine is installed on the deoxygenating equipment via the base plate 1, connecting the feeding pipe 5 to the feed end. The deoxygenating agent is added to the storage tank 2 via the feed hopper on the upper right side of the storage tank 2 for storage. When deoxygenating agent needs to be fed, the motor 8 drives the auger 9 to rotate, conveying the deoxygenating agent into the drying cylinder 41. The electric heating tube 44 heats the drying cylinder 41, thus drying the deoxygenating agent inside. This ensures the deoxygenating agent is dry before feeding, preventing it from becoming damp and affecting its performance. The solenoid valve at the left end of the drying cylinder 41 is opened to connect it to the screening box 3, allowing the dried deoxygenating agent to be fed into the drying cylinder. The deoxidizer enters the screening box 3 and is driven by the electric actuator 63 to rotate the connecting plate 65. The connecting plate 65 then drives the connecting plate 66 to rotate, causing the screen frame 68 to swing around the rotating shaft 611 to screen the deoxidizer, thereby improving product quality and preventing the deoxidizer from clogging the feeding pipe 5. This ensures smooth feeding. Clumped or large pieces of deoxidizer are collected by the collection box 610, ensuring that the deoxidizer is evenly fed into the equipment. The screened deoxidizer falls to the bottom of the screening box 3 and is fed into the feeding pipe 5 through the inclined bottom of the screening box 3.
[0032] like Figure 3 , Figure 4 As shown, the left and right sides of the inner cavity of the screening box 3 are provided with relief grooves 10, and the left relief groove 10 is lower than the right relief groove 10.
[0033] By setting the relief groove 10, the two ends of the screen frame 68 can move inside the two relief grooves 10, thus avoiding interference from the sizing box 3 on the swing of the screen frame 68.
[0034] like Figure 4 , Figure 5 As shown, the connecting plate 65 is V-shaped, and a rotating shaft 64 is fixedly installed on the lower left side of the rear side of the connecting plate 65. The rear end of the rotating shaft 64 is rotatably connected to the front left side of the screening box 3.
[0035] By setting a rotating shaft 64, the connecting plate 65 rotates around the rotating shaft 64, thereby pushing the screen frame 68 to move.
[0036] like Figures 4-6 As shown, a limiting rod 612 with an I-shaped cross section is fixedly installed on the right side of the rear side of the connecting plate 65. The connecting plate 66 is C-shaped, and a limiting groove 67 is opened through the front side of the connecting plate 66. The inner cavity of the limiting groove 67 is slidably connected to the outer side of the middle part of the limiting rod 612.
[0037] Through the action of the limiting rod 612 and the limiting groove 67, the connecting plate 65 pushes the connecting plate 66 and the rotating shaft 611 to rotate, thereby causing the screen frame 68 to swing around the rotating shaft 611 as the axis, which can screen the deoxidizer, improve the quality of the product, prevent the deoxidizer from clogging the feeding pipe 5, and ensure smooth feeding.
[0038] like Figures 3-5 , Figure 7 As shown, a spring 69 is fixedly installed on the left side of the lower top surface of the screen frame 68, and the end of the spring 69 away from the screen frame 68 is fixedly installed on the lower surface of the left relief groove 10.
[0039] The screen frame 68 can be reset by setting spring 69.
[0040] like Figures 1-8 As shown, an insulation tube 42 is fixedly installed on the outside of the drying cylinder 41, and the two ends of the electric heating tube 44 are fixedly installed on the left and right sides of the inner cavity of the insulation tube 42, respectively.
[0041] By setting up the insulation pipe 42, heat preservation can be achieved, reducing heat loss.
[0042] like Figures 1-8 As shown, a second motor 43 is fixedly installed on the right side of the drying cylinder 41, and a second auger 45 is fixedly installed at the output end of the second motor 43. An L-shaped connecting plate 46 is fixedly installed on the left side of the upper surface of the inner cavity of the drying cylinder 41, and the left end of the second auger 45 is rotatably connected to the inner cavity at the bottom of the connecting plate 46.
[0043] By setting the connecting plate 346, it is ensured that the auger 245 can carry out stable transmission.
[0044] The working principle of this utility model is as follows: In use, the feeding machine is installed on the deoxygenating equipment via the base plate 1, connecting the feeding pipe 5 to the inlet. The deoxygenating agent is added to the storage tank 2 via the feed hopper on the upper right side of the storage tank 2 for storage. When deoxygenating agent needs to be fed, the motor 8 drives the auger 9 to rotate, conveying the deoxygenating agent to the drying cylinder 41. The electric heating tube 44 heats the drying cylinder 41, thus drying the deoxygenating agent inside, ensuring it remains dry before feeding to prevent moisture from affecting its performance. The solenoid valve at the left end of the drying cylinder 41 is opened, connecting it to the screening box 3. The motor 43 drives the auger 45 to rotate, conveying the dried deoxygenating agent to... Inside the screening box 3, the electric push rod 63 drives the connecting plate 65 to rotate. Through the action of the limiting rod 612 and the limiting groove 67, the connecting plate 65 drives the connecting plate 66 and the rotating shaft 611 to rotate. This causes the screen frame 68 to swing around the rotating shaft 611, thus screening the deoxidizer, improving product quality, preventing the deoxidizer from clogging the feeding pipe 5, and ensuring smooth feeding. Clumped or large pieces of deoxidizer are collected by the collection box 610, ensuring that the deoxidizer can be evenly fed into the equipment. The screened deoxidizer falls to the bottom of the screening box 3. The inclined bottom of the screening box 3 causes the deoxidizer to fall into the feeding pipe 5 and be fed into the equipment through the feeding pipe 5.
[0045] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
