Description

Technical Field

[0001] The invention belongs to the technical field of alkali residue dehydration, and in particular relates to a multi-disc type alkali residue dehydrator. Background Art

[0002] During the production or treatment process, alkali residue will absorb moisture or come into contact with water, resulting in a high water content. In this case, the water in the alkali residue may mix with other substances in the subsequent treatment process to form wastewater.

[0003] Before recycling the alkali residue wastewater, it is usually necessary to dehydrate the alkali residue wastewater to facilitate the subsequent secondary utilization of the alkali residue. In the prior art, a centrifugal dehydrator is usually used to dehydrate the alkali residue. However, since most of the alkali residues come from the metallurgical industry, heavy metals will be contained in the alkali residues. The alkali residues can be used as a soil conditioner after subsequent recycling to improve the alkalinity or nutrient content of the soil. After the alkali residues are dehydrated by the centrifugal dehydrator, the heavy metals in the alkali residues will continue to remain in the alkali residues. When the alkali residues are subsequently used to improve the alkalinity of the soil, the heavy metals in the alkali residues will inhibit the activity of microorganisms in the soil and affect the health and fertility of the soil. In addition, when the alkali residues are dehydrated by the centrifugal dehydrator, the alkali residues in the centrifugal dehydrator need to be taken out after each dehydration of the alkali residues, and then the undehydrated alkali residues need to be put into the centrifugal dehydrator again. The process is complicated and the efficiency of alkali residue dehydration is greatly reduced.

[0040] Specifically, when the alkali residue needs to be dehydrated, multiple processing discs 6 can be used to dehydrate the alkali residue, so that the alkali residue is evenly distributed inside the multiple processing discs 6, thereby improving the efficiency of alkali residue dehydration. At the same time, the alkali residue and the heavy metals in the alkali residue can be separated to prevent the heavy metals in the alkali residue from inhibiting the microbial activity in the soil when the alkali residue is subsequently used to increase the alkalinity of the soil, thereby affecting the health and fertility of the soil and reducing the effect of subsequent reuse of the alkali residue. After completing the dehydration of the alkali residue, the alkali residue and the heavy metals in the alkali residue can be automatically taken out from the processing disc 6 separately, so as to facilitate the subsequent discharge component 16 to continue to transport the alkali residue into the processing cylinder 3, thereby greatly improving the working efficiency and reliability of the device when dehydrating the alkali residue.

[0041] The operating principle of the present invention is now described as follows:

[0042] In the present invention, when the alkali residue needs to be dehydrated, the alkali residue to be dehydrated is first put into the discharge barrel 162 from the opening at the upper end of the discharge barrel 162. At this time, the second motor 163 is controlled to start, driving the spiral rod 164 to rotate, so that the alkali residue in the discharge barrel 162 can flow downward evenly. In this process, the alkali residue will continuously enter the processing barrel 3 from the discharge pipe 165. At the same time, multiple second solenoid valves 166 are controlled to open, so that the alkali residue falls from the discharge pipe 165 to the processing disc 6. With the rotation of the spiral rod 164, uniform alkali residue will be stored in multiple processing discs 6. After multiple processing discs 6 contain the same amount of alkali residue in order from top to bottom, the corresponding second solenoid valves 166 are closed in turn to ensure that multiple processing discs 6 The same amount of alkali slag can be contained inside, which is convenient for subsequent dehydration of the alkali slag. After the processing cylinder 3 completes the dehydration of the alkali slag in the discharge cylinder 162, the second motor 163 is controlled to rotate in the reverse direction, so that the spiral rod 164 drives the alkali slag to move upward, and then the second motor 163 is controlled to rotate forward again, so that the alkali slag remaining in the discharge cylinder 162 re-enters the processing disc 6. After the alkali slag evenly enters the processing disc 6, the alkali slag is left to stand for a period of time to allow the alkali slag and the heavy metals contained in the alkali slag to be stratified, and the first motor 4 is controlled to start and drive the rotating rod 5 to rotate. During the rotation of the rotating rod 5, multiple processing discs 6 will be driven to rotate. At this time, the processing disc 6 will generate centrifugal force to throw the alkali slag and the heavy metals contained in the alkali slag to On the inner wall of the processing disc 6, since the mass of heavy metals is higher than that of alkali slag, heavy metals will remain at the lower end of the inner wall of the processing disc 6, while alkali slag will remain at the upper end of the inner wall of the processing disc 6, and the water in the alkali slag will flow from the water filter hole 7 opened at the bottom of the processing disc 6 to the next processing disc 6, and then flow downward through the water filter hole 7 again until it flows to the bottom of the processing cylinder 3. After all the water in the alkali slag flows to the bottom of the processing cylinder 3, the first solenoid valve 9 is controlled to open, and the sewage in the alkali slag is discharged through the drain pipe 8. Then, the third motor 114 is controlled to start, driving the first connecting rod 111 and the first baffle 112 to rotate, so that the first baffle 112 rotates toward the slag discharge shell 12 without blocking the slag outlet 10. Then, the fifth motor 144 is controlled to start, driving the first connecting rod 111 and the first baffle 112 to rotate. A round rod 143 rotates, so that the first round rod 143 drives the support plate 145 to rotate. When the tilt angle of the support plate 145 matches the angle of the inner wall of the processing disc 6, the fifth motor 144 is turned off, and then the first electric telescopic rod 141 is controlled to contract, so that the support plate 145 contacts the inner wall of the processing disc 6. At this time, as the processing disc 6 rotates, the alkali slag retained on the inner wall of the processing disc 6 will be blocked by the first push plate 148, so that the alkali slag is all retained on one side of the first push plate 148. After the processing disc 6 rotates one circle, the second electric telescopic rod 147 is controlled to start, so that the push plate pushes the alkali slag to one side of the slag outlet 10. At this time, due to the continuous rotation of the processing disc 6, the alkali slag will be thrown above the first guide plate 1110 under the action of centrifugal force, and then fall into the slag discharge shell 12.The alkali residue remaining on the surface of the first baffle plate 112 will also be thrown onto the first guide plate 1110 under the action of centrifugal force, thereby completing the collection of the alkali residue, and the dehydrated alkali residue will be discharged from the opening at the bottom of the slag discharge shell 12. After completing the collection of the dehydrated alkali residue in the processing disc 6, the above components are controlled to return to their original positions, and then the fourth motor 119 is controlled to start, so that the second connecting rod 116 and the second baffle plate 117 rotate toward one end of the heavy metal shell 13, so that the second baffle plate 117 does not block the discharge port 115, and then the third electric telescopic rod 151 is controlled to start, driving the second U-shaped plate 152 to move, and then the control The sixth motor 153 is started, driving the second round rod 154 to rotate, so that the inclination angle of the fixing plate 155 is the same as the angle of the inner wall of the processing disc 6, and then the fourth electric telescopic rod 157 is controlled to start, so that the fixing block 158 contacts the inner wall of the processing disc 6. Since the position of the fixing block 158 corresponds to the position of the heavy metal inside the processing disc 6 at this time, as the processing disc 6 rotates, the heavy metal inside the processing disc 6 will be blocked by the second push plate 1511. After the processing disc 6 rotates one circle, the heavy metal inside the processing disc 6 is all retained on the side of the second push plate 1511. Then the fifth electric telescopic rod 157 is controlled to start. 10 is started, driving the second push plate 1511 to move toward one end of the discharge port 115. Under the action of centrifugal force, the heavy metals in the processing disc 6 will be thrown above the second guide plate 1111, and thus enter the heavy metal discharge shell 13, and the heavy metals retained on the outer wall of the second baffle 117 will also be thrown above the second guide plate 1111 under the action of centrifugal force, and enter the heavy metal discharge shell 13. Finally, the heavy metals in the alkali residue will fall from the opening at the bottom of the heavy metal discharge shell 13, completing the collection of the heavy metals in the alkali residue. When the alkali residue needs to be dehydrated, multiple processing discs 6 can be used to dehydrate the alkali residue. The slag is evenly distributed inside the multiple processing discs 6, which improves the efficiency of dehydrating the alkali slag. At the same time, the alkali slag and the heavy metals in the alkali slag can be separated to prevent the heavy metals in the alkali slag from inhibiting the microbial activity in the soil when the alkali slag is used to increase the alkalinity of the soil, affecting the health and fertility of the soil, and reducing the effect of the subsequent reuse of the alkali slag. After the dehydration of the alkali slag is completed, the alkali slag and the heavy metals in the alkali slag can be automatically taken out from the processing disc 6 separately, which is convenient for the subsequent discharge component 16 to continue to transport the alkali slag to the processing cylinder 3, which greatly improves the working efficiency and reliability of the device when dehydrating the alkali slag.
