Description

Technical Field

[0001] The invention relates to a decolorization device, in particular to a decolorization device for acetic acid. Background Art

[0002] Latex thread is rubber thread, which is natural rubber and is taken from the sap of rubber trees. They are extremely precious because each rubber tree can only produce 30 ml of latex juice every day. Acetic acid is needed in the production of latex thread. In order to facilitate the recycling of acetic acid, the acetic acid needs to be decolorized.

[0003] The existing acetic acid decolorization treatment technology generally pours acetic acid and activated carbon into a container, manually stirs the acetic acid and activated carbon to decolorize the acetic acid, and then pours out the acetic acid and activated carbon and filters them to separate them. However, such operation firstly manually stirs the acetic acid and activated carbon, which is labor-intensive and inefficient. Secondly, after the acetic acid and activated carbon are discharged, they are filtered, which is troublesome to operate. The acetic acid and activated carbon are collected separately, and when the activated carbon is collected separately, the container opening is manually opened and it is fished out of the container, which is cumbersome and inconvenient to operate. Finally, the acetic acid may still contain particulate matter, which needs to be simply filtered before decolorization. When filtering with a filter, the filter may slip due to being not fixed.

[0004] Therefore, it is necessary to develop a device for acetic acid decolorization treatment that is convenient to open and seal a stirring tank and automatically stirs activated carbon and acetic acid to complete acetic acid decolorization. Summary of the invention

[0034] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0035] Example 1

[0036] like Figure 1 to Figure 6 As shown, this embodiment discloses an apparatus for acetic acid decolorization treatment, including a shell 1, a stirring tank 2, a hinge 3, a cover plate 4, a motor 5, a stirring rod 6, a dustproof component 7 and a closing component 8. The upper portion of the shell 1 is connected to the stirring tank 2, the upper rear side of the stirring tank 2 is rotatably connected to the cover plate 4, the cover plate 4 and the stirring tank 2 are symmetrically connected with the hinge 3, the motor 5 is installed in the middle of the upper portion of the stirring tank 2, the lower side of the output shaft of the motor 5 is connected to the stirring rod 6, the upper front side of the stirring tank 2 is provided with a dustproof component 7, and the lower portion of the stirring tank 2 is provided with a closing component 8.

[0037] The dustproof component 7 includes a support plate 71, a first baffle plate 72, a spur gear 73, a spur rack 74 and a first spring 75. The support plate 71 is connected to the front side of the upper part of the mixing tank 2. The first baffle plate 72 is rotatably connected to the front and rear sides of the upper inner part of the support plate 71. The outer side of the transmission shaft of the first baffle plate 72 is connected to the spur gear 73. The spur rack 74 is slidably connected to the left and right sides of the upper inner part of the support plate 71. The spur rack 74 and the spur gear 73 are meshed with each other. A first spring 75 is connected between the spur rack 74 and the support plate 71.

[0038] The closing assembly 8 includes a first guide rod 81, a second baffle 82, a second spring 83 and a first push rod 84. The first guide rod 81 is symmetrically connected to the rear side of the lower inner part of the mixing tank 2, the first push rod 84 is slidably connected between the first guide rods 81, the second spring 83 is symmetrically connected between the first push rod 84 and the mixing tank 2, the second spring 83 is sleeved on the first guide rod 81, and the second baffle 82 is connected to the inner side of the rear of the first push rod 84.

[0039] When the user needs to decolorize acetic acid, first turn the cover plate 4 counterclockwise to open it and pour the activated carbon into the stirring tank 2. In the initial state, the second baffle 82 blocks the lower opening of the stirring tank 2, and the activated carbon will not fall out. Loosen the cover plate 4. Under the action of gravity, the cover plate 4 turns clockwise to cover the stirring tank 2, and then the infusion tube for conveying acetic acid is inserted into the support plate 71. The infusion tube will push the spur rack 74 to move downward, and the first spring 75 is stretched, driving the spur gear 73 to rotate 90 degrees inward, thereby driving the first baffle 72 to rotate 90 degrees inward and open, so that acetic acid can flow smoothly into the stirring tank 2. After the stirring tank 2 is filled with sufficient acetic acid, take out the infusion tube and move away from the spur rack 74. Under the action of the first spring 75, the spur rack 74 is pushed to move upward, driving the spur gear 73 to rotate 90 degrees outward, thereby driving the first baffle 72 to rotate 90 degrees outward. The first push rod 84 is then pushed backwards, the second spring 83 is stretched, and the second baffle plate 82 is driven to move backwards, and no longer blocks the lower opening of the stirring tank 2, so that the acetic acid and the activated carbon can flow out, and the acetic acid and the activated carbon are caught under the stirring tank 2, and then the acetic acid and the activated carbon are filtered and separated. After the acetic acid and the activated carbon are completely discharged, the first push rod 84 is released, and under the action of the second spring 83, the first push rod 84 and the second baffle plate 82 are pushed forward, and the second baffle plate 82 blocks the lower opening of the stirring tank 2 again and returns to its original state, and so on and so forth, so as to facilitate the opening and sealing of the stirring tank 2, and automatically stir the activated carbon and the acetic acid to complete the decolorization of the acetic acid.

[0040] Example 2

[0041] like Figure 1, Figure 2 , Figure 7 to Figure 17 As shown, in some embodiments, a filter press assembly 9 is also included, and the filter press assembly 9 includes a filter plate 91, a cylinder 92, a pressure plate 93, a third baffle 94, a torsion spring 95, a storage frame 96 and a ball valve 97. The filter plate 91 is connected to the rear side of the middle inner part of the outer shell 1, and the cylinder 92 is installed on the front side of the middle inner part of the outer shell 1. The pressure plate 93 is connected to the rear side of the piston rod of the cylinder 92, and the pressure plate 93 cooperates with the filter plate 91. A storage frame 96 is connected to the lower part of the outer shell 1, and the third baffle 94 is rotatably connected to the front side of the upper part of the storage frame 96. Three torsion springs 95 are evenly connected between the third baffle 94 and the filter plate 91, and a middle rotatable ball valve 97 is provided on the rear side of the lower part of the storage frame 96.

[0042] It also includes an opening component 10, which includes a first support rod 101, a second support rod 102, a third spring 103, a second push rod 104, a fourth spring 105 and a first connecting rod 106. The first support rod 101 is connected to the front side of the upper part of the telescopic rod of the piston rod of the cylinder 92, the second support rod 102 is slidably connected to the upper part of the first support rod 101, the third spring 103 is connected between the second support rod 102 and the first support rod 101, the second push rod 104 is slidably connected to the rear side of the middle part of the second support rod 102, the second push rod 104 cooperates with the first push rod 84, and there is a fourth spring 105 between the second push rod 104 and the second support rod 102, the first connecting rod 106 is symmetrically connected to the left and right sides of the upper front side of the filter plate 91, and the first connecting rod 106 cooperates with the second support rod 102.

[0043] The cylinder 92 is started, and the piston rod of the cylinder 92 moves backward, driving the first support rod 101, the second support rod 102 and the second push rod 104 to move backward. The second push rod 104 will push the first push rod 84 to move backward, and finally drive the second baffle 82 to move backward. The acetic acid and activated carbon are smoothly discharged from the mixing tank 2 into the filter plate 91. At the same time, the piston rod of the cylinder 92 will also drive the pressing plate 93 to move backward to squeeze the acetic acid, and under the action of the filter plate 91, the acetic acid is filtered out and falls into the storage frame 96, and then turns 90 degrees. The ball valve 97 is moved to no longer block the drain port of the material storage frame 96, so that the decolorized acetic acid can be discharged smoothly. The ball valve 97 is then rotated 90 degrees in the opposite direction to close the material storage frame 96. After the first push rod 84 cannot move further, the second push rod 104 stops moving, and the second support rod 102 continues to move backward. The fourth spring 105 is compressed. At the same time, the second support rod 102 moves to contact the first connecting rod 106 and is pushed upward. The third spring 103 is stretched, driving the second push rod 104 to move upward away from the first push rod 84, so that the first push rod 84 and the second baffle 82 move forward to block the lower opening of the mixing tank 2, and under the action of the fourth spring 105, the second push rod 104 is pushed to move backward, and then the piston rod of the cylinder 92 moves forward, driving the first support rod 101, the second support rod 102 and the second push rod 104 to move forward. After the second support rod 102 moves away from the first connecting rod 106, under the action of the third spring 103, the second support rod 102 and the second push rod 104 move downward and return to the original state. At this time, the air cylinder 92 is closed and the second push rod 104 stops moving. The activated carbon remains on the filter plate 91 after filtration, pushing the third baffle plate 94 to rotate counterclockwise, causing the torsion spring 95 to deform and open the opening on the lower side of the filter plate 91, allowing the activated carbon to be discharged to the outside. The third baffle plate 94 is then released and, under the action of the torsion spring 95, the third baffle plate 94 is pushed to rotate clockwise to block the opening on the lower side of the filter plate 91 and return to its original state. This cycle is repeated to facilitate the filtration and separation of activated carbon and acetic acid, and to discharge and collect them separately.

[0044] It also includes a discharge assembly 11, which includes a push plate 111, a second connecting rod 112, a fifth spring 113, a wedge block 114, a sixth spring 115 and a third connecting rod 116. The push plate 111 is slidably connected to the rear side of the filter plate 91, and the second connecting rod 112 is connected to the rear side of the push plate 111. The second connecting rod 112 is slidably connected to the filter plate 91, and a fifth spring 113 is connected between the second connecting rod 112 and the filter plate 91. The wedge block 114 is symmetrically connected to the front side of the second connecting rod 112, and the wedge block 114 cooperates with the second support rod 102. The sixth spring 115 is connected between the wedge block 114 and the second connecting rod 112. The third connecting rod 116 is symmetrically connected to the front side of the middle part of the outer shell 1, and the third connecting rod 116 and the wedge block 114 cooperate with each other.

[0045] After the second support rod 102 moves backward until it contacts the wedge block 114, it pushes the wedge block 114 to move downward, and the sixth spring 115 is compressed. After the second support rod 102 moves through the wedge block 114, under the action of the sixth spring 115, the wedge block 114 is pushed upward to return to its original state. After the acetic acid is filtered, the second support rod 102 moves forward and resets. The second support rod 102 moves to contact the upper rear part of the wedge block 114, pushing the wedge block 114 forward, driving the second connecting rod 112 and the push plate 111 forward, and the fifth spring 113 is compressed, thereby driving the push plate 111 forward, pushing the residual activated carbon forward to the front side of the filter plate 91, and the activated carbon can be discharged after the third baffle 94 is turned counterclockwise to open, and then the wedge block 114 moves forward to contact After the third connecting rod 116 is moved, it will be pushed upward and the sixth spring 115 will be stretched. At this time, the second support rod 102 continues to move forward. Since the second support rod 102 is in contact with the lower rear part of the wedge block 114, it will be pushed downward by the wedge block 114. The third spring 103 is compressed. After the wedge block 114 moves away from the second support rod 102, under the action of the third spring 103, the second support rod 102 is pushed upward. At the same time, under the action of the fifth spring 113, the second connecting rod 112, the wedge block 114 and the push plate 111 are pushed backward. After the wedge block 114 is away from the third connecting rod 116, under the action of the sixth spring 115, the wedge block 114 is pushed downward and restored to its original state. This reciprocating process is used to automatically push the activated carbon forward, making it easier to discharge and collect the activated carbon.

[0046] It also includes a rotating component 12, which includes a ratchet gear 121, a fourth connecting rod 122, a ratchet bar 123 and a seventh spring 124.

[0047] When the second connecting rod 112 moves forward, it drives the ratchet bar 123 forward. After the ratchet bar 123 moves forward until it contacts the ratchet gear 121, under the action of the seventh spring 124, the ratchet gear 121 will not be driven to rotate. After the activated carbon is pushed to the front side of the filter plate 91, the second connecting rod 112 moves backward, driving the ratchet bar 123 backward, thereby driving the ratchet gear 121 to rotate counterclockwise, thereby driving the third baffle 94 to rotate counterclockwise, so that the activated carbon is discharged smoothly. After the ratchet bar 123 continues to move backward away from the ratchet wheel, the third baffle 94 rotates clockwise to reset, driving the ratchet gear 121 to rotate clockwise and return to its original state. This reciprocating process is repeated to achieve the effect of automatically rotating to open the third baffle 94, thereby facilitating the discharge of the activated carbon.

[0048] It also includes a coarse filter component 13, which includes a support frame 131, a filter screen 132 and a clamping rod 133. The support frame 131 is connected to the front side of the upper part of the mixing tank 2, and the filter screen 132 is placed inside the support frame 131. The filter screen 132 is located on the inner side of the lower part of the mixing tank 2. The clamping rod 133 is connected to the front and rear sides of the lower part of the right spur gear 73, and the clamping rod 133 cooperates with the support frame 131.

[0049] When the spur rack 74 moves downward, it will drive the clamping rod 133 to move downward, so that the clamping rod 133 is inserted into the support frame 131, the support frame 131 and the filter screen 132 are fixed, and the particulate matter in the acetic acid is filtered out. After a sufficient amount of acetic acid is loaded into the mixing tank 2, the spur rack 74 moves upward, and drives the clamping rod 133 to move upward and away from the support frame 131, and then the support frame 131 and the filter screen 132 can be pulled to the right, and then the particulate matter on the filter screen 132 is cleaned off, and then the support frame 131 and the filter screen 132 are pushed back to the original position, and this reciprocating process is repeated to achieve the effect of stably and roughly filtering the particulate matter in the acetic acid.
