[0026] As a preferred embodiment of the present invention, it further includes an air intake mechanism for preventing the diffusion of oxalic acid powder, the air intake mechanism comprising:

[0027] A sliding rod is provided; an air inlet is located on the upper front side of the feed frame; and a sliding rod is slidably connected to the upper front side of the feed frame.

[0028] A sealing plate is connected to the rear side of the sliding rod to block the air inlet. The sealing plate moves to block the air inlet and prevent oxalic acid powder from spreading through the air inlet.

Detailed Implementation

[0052] The present invention will now be further described with reference to the accompanying drawings and specific embodiments:

[0053] Example 1

[0054] An oxalic acid feeding and discharging device, such as Figure 1 and Figure 2 As shown, it includes a mixing tank 1, a discharge pipe 2, a feeding frame 3, a separating net 4, a covering mechanism 5, and an absorption mechanism 6. The bottom of the mixing tank 1 is connected to the discharge pipe 2. The feeding frame 3 is welded to the top left side of the mixing tank 1. The separating net 4 is connected inside the feeding frame 3. The separating net 4 is used to limit the oxalic acid packaging bag. The covering mechanism 5 is provided on the upper right side of the feeding frame 3. The covering mechanism 5 is used to block the oxalic acid. The absorption mechanism 6 is provided between the top of the mixing tank 1 and the feeding frame 3. The absorption mechanism 6 is used to absorb the oxalic acid.

[0055] like Figure 1 and Figure 3 As shown, the covering mechanism 5 includes a cover 51, a hinge 52, an observation window 53, and a handle 54. The cover 51 is connected to the upper right side of the feed frame 3 via the hinge 52. The cover 51 is used to limit the oxalic acid. The top of the cover 51 is embedded with an observation window 53, which is used to observe the feeding of oxalic acid. A handle 54 is welded to the left side of the cover 51.

[0056] like Figure 1 , Figure 4 and Figure 5As shown, the absorption mechanism 6 includes a motor 61, a first bevel gear 62, a second bevel gear 63, a support frame 64, and a blade 65. The motor 61 is bolted to the top left side of the mixing tank 1. The motor 61 is located on the right side of the feed frame 3. The output shaft of the motor 61 passes through the lower right side of the feed frame 3. The first bevel gear 62 is connected to the left side of the output shaft of the motor 61 by a key. The support frame 64 is welded to the lower side inside the feed frame 3. The blade 65 is rotatably connected to the middle of the support frame 64. The blade 65 is used to drive the oxalic acid to flow downward. The second bevel gear 63 is connected to the lower side of the blade 65 by a key. The first bevel gear 62 meshes with the second bevel gear 63.

[0057] In use, the discharge pipe 2 is blocked with a blocking block. Then, the operator manually grasps handle 54 and rotates the cover 51 to the right to open it, moving the observation window 53. The entire bag of oxalic acid is then cut open and placed into the feed frame 3 with the opening facing down, so that the entire bag of oxalic acid is positioned on the isolation net 4. The isolation net 4 prevents the oxalic acid packaging bag from entering the mixing tank 1. The cover 51 is then closed to prevent oxalic acid powder from spreading out of the feed frame 3 during feeding, which could cause great harm to the operator, thus improving safety. The motor 61 is then started, and the output shaft of the motor 61 drives the first cone. The first bevel gear 62, the second bevel gear 63, and the impeller 65 rotate, causing oxalic acid to fall through the isolation net 4. The rotation of the impeller 65 generates suction, accelerating the falling speed of the oxalic acid and further preventing its diffusion. The oxalic acid falls into the mixing tank 1 for subsequent mixing. The operator observes the feeding of oxalic acid through the observation window 53. Once the oxalic acid feeding is complete, the motor 61 is turned off. After mixing is complete, the block is removed, allowing the mixture to be discharged through the discharge pipe 2. After discharge, the block is reset, the cover 51 is opened, the oxalic acid packaging bag is removed, and then the cover 51 is reversed and reset.

[0058] Example 2

[0059] Based on Example 1, such as Figure 1 , Figure 6 and Figure 7 As shown, it also includes a bag opening mechanism 7, which is used to automatically cut open the oxalic acid packaging bag. The bag opening mechanism 7 includes a guide rail 71, a slide rod 72, a blade 73, and a first connecting frame 74. The guide rail 71 is welded to the upper part of the feed frame 3. The guide rail 71 has a discharge port on the left side. The bottom of the guide rail 71 is in contact with the isolation net 4. The slide rod 72 is slidably connected inside the guide rail 71. The slide rod 72 is slidably connected to the upper right side of the feed frame 3. The first connecting frame 74 is welded to the lower right side of the hinge 52. The lower part of the first connecting frame 74 is slidably connected to the right side of the slide rod 72. The blade 73 is connected to the upper left side of the slide rod 72. The blade 73 is used to automatically cut open the oxalic acid packaging bag.

[0060] When the cover 51 is rotated open, it drives the hinge 52 to rotate. The hinge 52 drives the first connecting frame 74 to rotate downward, pushing the slide bar 72 and the blade 73 to move to the left. Then, the worker places the whole bag of oxalic acid on the isolation net 4, so that the blade 73 is inserted into the oxalic acid. Then the cover 51 is closed, and the cover 51 drives the hinge 52 to reverse and reset. The hinge 52 drives the first connecting frame 74 to reverse, thereby driving the slide bar 72 and the blade 73 to move to the right and reset, so that the blade 73 cuts open the oxalic acid packaging bag. In this way, the worker does not need to cut open the oxalic acid packaging bag in advance, avoiding the spread of oxalic acid powder that may burn the worker when cutting, further improving safety. Since there is a discharge port on the left side of the guide rail 71, the oxalic acid that falls into the guide rail 71 can be discharged through the discharge port, thereby preventing the oxalic acid from accumulating in the guide rail 71 and affecting the movement of the slide bar 72.

[0061] like Figure 1 and Figure 8 As shown, it also includes an air intake mechanism 8, which is used to prevent the diffusion of oxalic acid powder. The air intake mechanism 8 includes a sealing plate 81, a sliding rod 82 and a compression spring 83. An air inlet is opened on the upper front side of the feed frame 3. The sliding rod 82 is slidably connected to the upper front side of the feed frame 3. A sealing plate 81 is welded to the rear side of the sliding rod 82. The sealing plate 81 is used to block the air inlet. A compression spring 83 is sleeved on the front side of the sliding rod 82. The two ends of the compression spring 83 are respectively connected to the front side of the sliding rod 82 and the front side of the feed frame 3.

[0062] When the fan blade 65 rotates, it generates suction, which moves the sealing plate 81 backward and the sliding rod 82 backward. At this time, the compression spring 83 is compressed, allowing air to enter the feed frame 3. This helps the fan blade 65 to accelerate the intake of oxalic acid into the mixing tank 1. When the fan blade 65 stops, the suction disappears, and the compression spring 83 returns to its original position. This causes the sliding rod 82 and the sealing plate 81 to move forward and block the air inlet, preventing the oxalic acid powder from spreading out through the air inlet. In this way, the oxalic acid powder can be kept within a certain range.

[0063] like Figure 1 and Figure 9 As shown, it also includes a shaking mechanism 9, which is used to shake the oxalic acid. The shaking mechanism 9 includes a cam 91, a second connecting frame 92 and a push plate 93. The cam 91 is connected to the right side of the output shaft of the motor 61. The eccentric position of the cam 91 is connected to the output shaft of the motor 61. The second connecting frame 92 is slidably connected to the right side of the feed frame 3. The bottom of the second connecting frame 92 contacts the cam 91. Push plates 93 are welded to both the front and rear sides of the upper left part of the second connecting frame 92. The push plates 93 are used to drive the oxalic acid to shake up and down. The push plates 93 are located on the upper side of the isolation net 4.

[0064] The entire bag of oxalic acid is placed on the push plate 93. When the output shaft of the motor 61 rotates, it drives the cam 91 to rotate. Since the cam 91 is eccentrically connected to the output shaft of the motor 61, as the cam 91 rotates, it drives the second connecting frame 92 to move upward, thereby driving the push plate 93 and the entire bag of oxalic acid to move upward together. Under the gravity of the oxalic acid, the push plate 93 and the second connecting frame 92 move downward and reset together with the rotation of the cam 91. In this way, the cam 91 continuously drives the second connecting frame 92 to move up and down, causing the second connecting frame 92 to drive the push plate 93 and the entire bag of oxalic acid to shake up and down, thereby shaking off the oxalic acid in the packaging bag and preventing the oxalic acid in the packaging bag from not being completely discharged. When the motor 61 stops, the cam 91 stops rotating.

[0065] like Figure 1 and Figure 10 As shown, it also includes a closing mechanism 10, which is used to close the lower part of the feed frame 3. The closing mechanism 10 includes a connecting rod 101, a baffle 102, a guide sleeve 103, and a fixing plate 104. The bottom right side of the slide rod 72 is connected to the connecting rod 101, and the lower left side of the connecting rod 101 is welded with the baffle 102, which is used to block the blade 65. The lower right side of the feed frame 3 is connected with the guide sleeve 103, and the baffle 102 and the guide sleeve 103 are slidably connected. The lower front and rear sides of the inner lower part of the feed frame 3 are welded with fixing plates 104. After the baffle 102 moves, it contacts the fixing plate 104 and closes the lower part of the feed frame 3.

[0066] When the slide bar 72 moves to the left, it drives the connecting rod 101 to move to the left, thereby driving the baffle 102 to move to the left, so that the baffle 102 contacts the fixed plate 104 to close the lower part of the feed frame 3, preventing the oxalic acid powder in the mixing tank 1 from spreading through the feed frame 3 when the operator opens the cover 51. When the slide bar 72 moves to the right to reset, it drives the connecting rod 101 and the baffle 102 to move to the right to reset, so that the baffle 102 no longer blocks the lower part of the feed frame 3.

[0067] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.
