The feed component 2 comprises a feed hopper 21 arranged on the top surface of the filter separation component 1, a temporary storage cavity 22 is arranged in the inner cavity of the filter separation component 1, a through pipe 23 is arranged at the bottom of the temporary storage cavity 22, a quantity control box 24 is arranged at the bottom of the through pipe 23, a feed pipe 28 is arranged at the lower end of the quantity control box 24, the feed hopper 21, the temporary storage cavity 22, the through pipe 23, the quantity control box 24 and the feed pipe 28 are connected to each other, a centrifugal cylinder component 12 is arranged in the inner cavity of the filter separation component 1, and the feed pipe 28 is arranged directly above the centrifugal cylinder component 12.

[0026] The feeding assembly 2 also includes a first motor 25 arranged inside the filter separation assembly 1, and one side of the first motor 25 is rotatably connected to a first positive and negative screw rod 27, and the first positive and negative screw rod 27 is connected to the output end of the first motor 25. The moving plates 26 all pass through the strip opening on the side wall of the quantity control box 24 and extend to the inner cavity of the quantity control box 24. The two groups of moving plates 26 are horizontally slidably connected to the strip opening of the quantity control box 24 left and right; the inner cavity of the quantity control box 24 is also slidably connected to a sliding plate 29, and two groups of sliding plates 29 are provided. The two groups of sliding plates 29 match the bottom opening of the through pipe 23, and the two groups of sliding plates 29 are fixedly connected to the two groups of moving plates 26 respectively.

[0027] The aminosulfonic acid material is passed through the feed hopper 21 into the temporary storage chamber 22 for temporary storage, and the amount of material discharged from the temporary storage chamber 22 is adjusted by the amount control box 24: the first motor 25 is turned on to make the first motor 25 rotate forward or reverse, and the first motor 25 drives the first forward and reverse screw rod 27 to rotate, at this time, the two groups of moving plates 26 will move closer to or away from each other, and then the two groups of sliding plates 29 will move closer to or away from each other under the through pipe 23, and the opening and closing degree of the two groups of sliding plates 29 under the through pipe 23 can determine the amount of material in the temporary storage chamber 22 that is passed into the centrifugal cylinder component 12. When the two groups of sliding plates 29 are combined and contacted with each other, that is, the opening under the through pipe 23 is closed, that is, the feeding opening is closed, and the material in the temporary storage chamber 22 is not discharged; if the two groups of sliding plates 29 are opened and closed to the maximum distance, that is, the feeding opening of the through pipe 23 is opened to the maximum, the aminosulfonic acid in the temporary storage chamber 22 is discharged at the fastest speed.

[0028] When the two sets of sliding plates 29 are adjusted to a suitable distance, the first motor 25 is turned off, and the material in the temporary storage chamber 22 will flow into the centrifugal cylinder component 12 along the through pipe 23, the quantity control box 24 and the movable plate 26.

This setting can control the feeding of aminosulfonic acid through the feeding component 2, which is convenient for users to adjust according to actual conditions, expand the use range of the device, and improve the separation effect of the equipment.

[0029] A bottom cavity seat assembly 3 is provided at the bottom of the filter separation assembly 1, and counterweight slot blocks 4 are provided on both sides of the bottom cavity seat assembly 3. A discharge pipe 11 is provided on one side of the filter separation assembly 1. The filter separation assembly 1 is connected to the centrifugal cylinder component 12. Limiting grooves 31 are provided on both sides of the bottom cavity seat assembly 3, and the inner cavities of the two groups of limiting grooves 31 are slidably connected with clamping blocks 32; the counterweight slot block 4 matches the clamping block 32 and can be clamped and connected.

[0030] A second motor 33 is provided in the inner cavity of the bottom cavity seat assembly 3, and a first roller 34 is rotatably connected to the inner cavity of the bottom cavity seat assembly 3. The first roller 34 is connected to the output end of the second motor 33, and a second positive and negative screw rod 37 is rotatably connected to the inner cavity of the bottom cavity seat assembly 3. A second roller 36 is fixedly connected to the middle part of the second positive and negative screw rod 37, and a belt 35 is sleeved between the second roller 36 and the first roller 34. Both ends of the second positive and negative screw rod 37 pass through the bottom cavity seat assembly 3 and extend to the outside of the limiting groove 31, and two groups of blocks 32 are respectively threadedly connected to the outer periphery of both ends of the second positive and negative screw rod 37.

[0031] In order to make the filter separation component 1 and the centrifugal drum component 12 more stably placed during use, a bottom cavity seat component 3 and a counterweight slot block 4 are added to the bottom of the filter separation component 1. When it is necessary to make the bottom cavity seat component 3 more stably placed, the two groups of counterweight slot blocks 4 are pre-placed on one side of the two groups of clamping blocks 32 respectively. At this time, the positions of the counterweight slot blocks 4 and the clamping blocks 32 match and correspond. At this time, the second motor 33 in the inner cavity of the bottom cavity seat component 3 is started, and the second motor 33 rotates forwardly to drive the first roller 34 to rotate. The first roller 34 can rotate the second roller 36 through the belt 35, and the second roller 36 drives the second forward and reverse screw rod 37 to rotate forwardly. Since the block 32 is limited to slide in the inner cavity of the limit groove 31, the two groups of block 32 will extend outward along the limit groove 31 until the block 32 is completely extended into the cavity in the middle of the counterweight groove block 4, and the block 32 can be engaged with the counterweight groove block 4. The two groups of counterweight groove blocks 4 are installed and fixed on both sides of the bottom cavity seat assembly 3. This operation increases the floor space of the bottom cavity seat assembly 3, making the filter separation assembly 1 placed on the top surface of the bottom cavity seat assembly 3 more stable. By adding the counterweight groove block 4, the center of gravity of the object can be changed, so that the bottom cavity seat assembly 3 and the filter separation assembly 1 are firmly on the ground surface, so that the centrifugal drum component 12 can maintain balance when rotating, avoiding the filter separation assembly 1 from shaking greatly, which may cause safety hazards.

[0032] When it is necessary to separate the counterweight slot block 4 from the bottom cavity seat assembly 3, the second motor 33 is rotated in the opposite direction and then through the transmission component, the second forward and reverse screw rod 37 is rotated in the opposite direction. The second forward and reverse screw rod 37 will drive the two groups of blocks 32 to move closer to each other, that is, the block 32 shrinks toward the inner cavity of the limiting groove 31 until the block 32 is completely separated from the counterweight slot block 4. The counterweight block can be removed, which is convenient for users to maintain the equipment. This setting can achieve the stability of the filter separation assembly 1 during operation, avoid its tipping over, and improve the safety of the device through the coordinated use of the bottom cavity seat assembly 3 and the counterweight slot block 4.

[0033] In summary: the utility model discloses a separation device for an aminosulfonic acid vacuum filter. A vacuum filter is a common filtering device, which mainly performs filtering under a vacuum state, that is, using a vacuum pump or other device to extract air or gas in a pipeline, so that the pressure in the pipeline is lower than the atmospheric pressure, thereby causing negative pressure. The vacuum filter can filter moisture in the air. This is due to the working principle of the vacuum filter. During the processing of aminosulfonic acid, solid-liquid separation is required, so a separation device of a vacuum filter is required. However, most of the existing filter separation components 1 directly pour the aminosulfonic acid raw materials at one time when feeding, which easily causes too much aminosulfonic acid to be fed at one time, resulting in poor separation effect.
