Description

Technical Field

[0001] The invention relates to the technical field of deoxidizer production, and in particular to a high-efficiency deoxidizer production process and production equipment. Background Art

[0002] Deoxidizer is a chemical product used to preserve food and prevent mildew. It is usually a small package containing reduced iron powder and can be placed together with food. It can remove oxygen from the food bag, slow down the oxidation of food, and play a role in moisture-proof, mildew-proof, and freshness-preserving.

[0003] According to the publication (announcement) number CN116849317A, the publication (announcement) date is 2023.10.10, and a deoxidizer is disclosed, which is composed of the following raw materials in weight percentage: 52%-58% reduced iron powder, 0.5%-2% activated carbon, 7%-11% electrolyte, 13%-23% water, 11%-18% super absorbent resin, wherein the electrolyte is one of sodium chloride, calcium chloride, and potassium bromide. The device is fixedly provided with a barrel on a base, a rotating shaft is rotatably provided in the barrel, and stirring blades are provided on the circumference of the rotating shaft. While the stirring blades drive the pressure plate to rotate, the pressure plate moves downward through a threaded connection with the inner wall of the barrel, which can effectively extrude the deoxidizer raw material.

[0004] In the prior art including the above patents, the main component of the deoxidizer that absorbs oxygen is reduced iron powder. Reduced iron powder is easily oxidized to produce iron oxide to absorb oxygen, thereby achieving the purpose of deoxidation. Moreover, the cost of reduced iron powder is very low, and the recovered reduced iron powder can be used to perform a reduction reaction to obtain reduced iron powder. Most deoxidizers are powders, which are formed by fully mixing a variety of effective substances and then packaging them to form the common bagged deoxidizers on the market. However, since the powdered materials do not have fluidity, it is difficult to fully mix a variety of powdered materials, especially the reduced iron powder that accounts for 50% or even more of the total mass of the deoxidizer. During the mixing process, the reduced iron powder is difficult to be evenly dispersed in the material, resulting in different contents of each component of the packaged deoxidizer, which affects the actual working effect and working time of the deoxidizer.

The output torque of the motor drives the gear to rotate, and the gear drives the driving ring 137 engaged with it to rotate. The limit block on the driving ring 137 drives the feeding pipe 11 to rotate. At the same time, the protrusion on the processing kettle 1 moves along the guide groove on the feeding pipe 11, driving the feeding pipe 11 and the discharge pipe 12 to spirally rise.

[0057] As a further embodiment of the present invention, a sliding ring 128 coupled to the first impeller 121 is slidably disposed in the discharge pipe 12 , and the second impeller 122 rotates to make the sliding ring 128 reciprocate along the discharge pipe 12 .

[0058] Specifically, a fixed plate 123 is provided inside the discharge pipe 12, and a notch is provided on the fixed plate 123 for the reduced iron powder to pass through. A shift block 125 is provided on the second impeller 122 and extends into a sliding ring 128. The sliding ring 128 is slidably installed in the discharge pipe 12. A second guide groove 126 adapted to the shift block 125 is provided on the inner wall of the sliding ring 128.

At this time, the second impeller 122 rotates to put the reduced iron powder on it into the vertical notch near the bottom of the discharge pipe 12, and slowly releases it, and at the same time, the shifting block 125 on the second impeller 122 moves along the second guide ring 128.

[0060] As another embodiment further provided by the present invention, a transverse notch connected to the vertical notch is provided at the bottom of the discharge pipe 12, and a blocking strip 124 is hinged at the connection between the transverse notch and the vertical notch.

[0061] Specifically, a torsion spring is provided between the material blocking bar 124 and the discharge pipe 12 .

[0062] Furthermore, in the process of the feed pipe 11 driving the discharge pipe 12 to rotate and move upward, the discharge pipe 12 pushes the material in the processing kettle 1 and leaves a chamber at the rear of the discharge pipe 12 and at the horizontal notch, so as to facilitate the reduced iron powder in the vertical notch to flow out from the vertical notch, so as to evenly sprinkle the reduced iron powder into the material, and the material blocking bar 124 can limit the amount of reduced iron powder flowing out, thereby avoiding the accumulation of a large amount of reduced iron powder in the processing kettle 1.

[0063] As another embodiment further provided by the present invention, a connecting bar 114 is movably provided on the processing kettle 1 , and the connecting bar 114 extends to the inside of the material conveying pipe 11 and is provided with a knocking block 116 for knocking the material discharging pipe 12 .

[0065] Furthermore, in the process that the feed pipe 11 drives the discharge pipe 12 to rotate and move upward, the connecting bar 114 rotates with the feed pipe 11 and moves downward relative to the feed pipe 11. The knocking block 116 on the connecting bar 114 knocks the feed pipe 11, so that the reduced iron powder in the feed pipe 11 can move downward smoothly, avoiding the reduced iron powder from bridging in the feed pipe 11.

[0066] As another embodiment further provided by the present invention, a cavity for accommodating the knocking block 116 is opened on the material conveying pipe 11 , and a paddle 112 for receiving the knocking block 116 is arranged on the side wall of the cavity.

[0067] Specifically, a connecting piece 115 is provided between the connecting strip 114 and the striking block 116 , the connecting piece 115 has a certain elasticity, and the paddle 112 is a metal piece with a certain elasticity.

[0068] Furthermore, in the process of the feed pipe 11 driving the discharge pipe 12 to rotate and move upward, the knocking block 116 squeezes the paddle 112, and the paddle 112 and the connecting piece 115 are deformed and accumulate elastic potential energy. When the deformation degree of the paddle 112 is too large and the knocking block 116 is separated from the paddle 112, the connecting piece 115 releases the accumulated elastic potential energy, driving the knocking block 116 to collide with the next paddle 112, and transmits the vibration to the feed pipe 11 through the paddle 112, so that the feed pipe 11 vibrates, so that the reduced iron powder therein falls smoothly.

[0069] As another embodiment further provided by the present invention, a notch is opened in the material conveying pipe 11 surrounding the internal channel thereof, and a movable bar 111 is slidably arranged inside the notch. The movable bar 111 moves to make the space of the internal channel adjustable.

[0070] Specifically, in the process that the feed pipe 11 drives the discharge pipe 12 to rotate and move upward, the movable bar 111 moves relative to the feed pipe 11, changing the space of the internal channel of the feed pipe 11, so that the reduced iron powder falls smoothly, and the movable bar 111 also squeezes the reduced iron powder in the feed pipe 11 when moving, and squeezes part of the reduced iron powder into the discharge pipe 12.

[0071] As another embodiment further provided by the present invention, a guide ring 131 is axially slidably provided on the processing kettle 1 for guiding the movement of the movable bar 111 , and a tenon block 138 extending into the guide ring 131 is provided on the movable bar 111 .

[0072] Specifically, a connecting tube 132 is provided between the guide ring 131 and the pan head 13. The connecting tube 132 is specifically a telescopic tube. The telescopic tube limits the guide ring 131 to move up and down with the feed pipe 11 without rotating. A first guide groove 133 adapted to the tenon 138 is provided at the bottom of the guide ring 131. The first guide groove 133 includes an inner ring 134 and an outer ring 135 and a connecting portion 136 connecting the inner ring 134 and the outer ring 135.

[0073] Furthermore, in the process of the feed pipe 11 driving the discharge pipe 12 to rotate and move upward, the feed pipe 11 rotates relative to the guide ring 131, and the tenon 138 on the movable bar 111 moves along the inner ring 134 of the first guide groove 133. At this time, the internal channel space of the feed pipe 11 is the smallest, and the feed pipe 11 continues to rotate, and the tenon 138 moves along the connecting portion 136 and enters the outer ring 135. At this time, the internal channel space of the feed pipe 11 is increased, which facilitates the smooth falling of the reduced iron powder in the feed pipe 11. The feed pipe 11 continues to rotate, and the tenon 138 moves along the connecting portion 136 and enters the inner ring 134. The internal channel space of the feed pipe 11 is reduced, squeezing the reduced iron powder therein and pushing the reduced iron powder into the discharge pipe 12.

[0074] As another embodiment further provided by the present invention, a conical pushing plate 14 is disposed at the bottom of the material conveying pipe 11 , and arc-shaped guiding strips 141 distributed in a circular array are disposed on the pushing plate 14 .

[0075] Specifically, a first gear 117 is provided on the connecting bar 114, the first gear 117 extends to the bottom of the connecting bar 114 and is provided with a second gear 118, a gear ring meshing with the first gear 117 is provided on the pan head 13, a transmission cylinder 113 meshing with the second gear 118 is rotatably provided in the feed pipe 11, a transmission wheel 129 coupled with the second impeller 122 is rotatably provided in the discharge pipe 12, and a bevel gear coupled with the bottom of the transmission cylinder 113 is provided on the transmission wheel 129.

[0076] Furthermore, during the operation, the motor output torque drives the gear to rotate, and the gear drives the driving ring 137 meshing with it to rotate, and the limit block on the driving ring 137 pushes the delivery pipe 11 to rotate, and at the same time, the protrusion on the processing kettle 1 moves along the guide groove on the delivery pipe 11, driving the delivery pipe 11 and the discharge pipe 12 to spirally rise, and the delivery pipe 11 drives the connecting bar 114 to rotate relative to the pan head 13, and the first gear 117 on the connecting bar 114 is shifted by the gear ring, and the first gear 117 drives the transmission cylinder 113 to rotate through the second gear 118, and the transmission cylinder 113 drives the transmission wheel 129 to rotate through the bevel gear, thereby driving the second impeller 122 coupled to the transmission wheel 129 to rotate, pushing the reduced iron powder near the bottom end of the discharge pipe 12 to the vertical notch on the discharge pipe 12, and slowly releasing it to the material in the processing kettle 1 through the vertical notch. The material in the processing kettle 1 is pushed into the material, and the second impeller 122 drives the first impeller 121 to rotate intermittently to push the reduced iron powder near the upper end of the discharge pipe 12 into the vertical groove of the discharge pipe 12, and gradually sprinkle it into the material in the processing kettle 1. The discharge pipe 12 sprinkles the reduced iron powder on the spiral upward curved surface in the processing kettle 1, and the pushing plate 14 moves up with the rotation of the conveying pipe 11. The conical pushing plate 14 pushes the material in the processing kettle 1 to move, and the arc-shaped guide strip 141 thereon can guide the material in the middle of the processing kettle 1 to move around so that the discharge pipe 12 can stir, and the conical pushing plate 14 can seal the stirring dead angle between the two discharge pipes 12 to prevent the material at the bottom center of the processing kettle 1 from participating in the stirring. After the conveying pipe 11 reaches the highest point, the motor continues to work, driving the conveying pipe 11 and the discharge pipe 12 to spirally move downward to continue the stirring and spreading work.

[0077] As another embodiment further provided by the present invention, a material-push wheel 142 is rotatably provided at the bottom of the processing kettle 1 for pushing the bottom material upward, and a sealing cylinder 143 is provided at the bottom of the pushing plate 14. The sealing cylinder 143 moves upward to rotate the material-push wheel 142.

[0078] Specifically, the sealing cylinder 143 seals the chamber between the pushing plate 14 and the processing kettle 1 to prevent the material from moving to the bottom of the pushing plate 14, and when the sealing cylinder 143 reciprocates in the vertical direction with the pushing plate 14, the sealing cylinder 143 drives the material wheel 142 to rotate, and the inclined blades on the material wheel 142 push the material at the bottom of the processing kettle 1 to move upward, thereby realizing the exchange of materials in the processing kettle 1.

[0079] Furthermore, in the above embodiment, a guide groove similar to the reciprocating screw rod may be opened on the outer wall of the sealing cylinder 143, and a protrusion adapted to the guide groove is provided on the material discharging wheel 142. During the reciprocating movement of the sealing cylinder 143 in the vertical direction, the guide groove thereon pushes the material discharging wheel 142 to rotate continuously, thereby pushing the material at the bottom of the processing kettle 1 to move upward.

[0080] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
