Description

Technical Field

[0001] This utility model relates to the field of activated clay production technology, and more specifically, to a high-efficiency water circulation purification device for activated clay production. Background Technology

[0002] Activated clay is an adsorbent made from clay, mainly bentonite, as raw material, through inorganic acidification, salting, or other methods, followed by water washing and drying. It appears as a milky white powder, is odorless, tasteless, and non-toxic, and has strong adsorption properties, capable of adsorbing colored and organic substances.

[0003] During the production of activated clay, inorganic acids are required for treatment, often sulfuric acid or hydrochloric acid. After treatment, water washing is necessary. The wastewater generated during washing often contains unreacted sulfuric acid, which needs to be removed. The traditional removal method is to add alkali, which requires workers to manually mix the alkali into the wastewater. After the reaction is complete, a neutral salt solution is generated. The whole process is quite cumbersome. During the later filtration, the precipitate easily clogs the filter mechanism, resulting in a decrease in the efficiency of continuous circulation treatment. Cleaning the filter mechanism is also quite troublesome. Further improvements can be made. Utility Model Content

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a high-efficiency water circulation purification device for activated clay production, which has the following beneficial effects: (1) This utility model is equipped with a mixing chamber and a filter tank. During the production of activated clay, the wastewater containing sulfuric acid is introduced into the mixing chamber through the inlet pipe. The servo motor on the top of the feeding box starts and drives the rotating rod and auger blades to rotate, conveying the calcium hydroxide powder inside the feeding box to the top of the spreading plate. The first drive motor drives the main shaft to rotate, which drives the stirring blades and the spreading plate to rotate synchronously. The rotating spreading plate evenly sprinkles the calcium hydroxide powder into the wastewater containing sulfuric acid. The stirring blades stir and mix the wastewater and calcium hydroxide powder to form calcium sulfate precipitate. Then, the gate valve opens, and the calcium sulfate precipitate, along with the treated wastewater, is released into the wastewater. Wastewater is injected into the filter tank, and the second drive motor drives the rotating drum to rotate, which in turn drives the inner drum to rotate, performing centrifugal filtration to remove calcium sulfate precipitate and complete wastewater purification. The purified wastewater flows back along the circulation pipe to continue participating in the water washing process, completing continuous circulation purification and utilization. This device uses alkali neutralization, stirring and mixing, and centrifugal filtration to achieve continuous circulation treatment of wastewater. The process is highly efficient and rapid, improving work efficiency. At the same time, the feeding plate improves the uniformity of calcium hydroxide addition, eliminates the trouble of manual feeding, and improves the convenience of use. The use of centrifugal filtration results in higher filtration effect, faster speed, less clogging, and higher work efficiency.

[0014] (2) This utility model is equipped with an inner cylinder that is easy to clean. When there is a lot of sediment inside the inner cylinder, the staff can lift the inner cylinder and move it out of the rotating drum for cleaning. After cleaning, the insertion hole is aligned with the insertion post and then inserted into the inner cylinder. The insertion post passes through the insertion hole to complete the reinstallation and the centrifugal filtration work can be carried out again. The cleaning and maintenance are very convenient, which further improves the convenience of use and work efficiency. Attached Figure Description

[0018] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0019] According to an embodiment of the present invention, a high-efficiency water circulation purification device for the production of activated clay is provided.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Please refer to them. Figure 1 and Figure 2 According to an embodiment of this utility model, a high-efficiency water circulation purification device for the production of activated clay includes a mixing chamber 1 and a filter tank 9. The mixing chamber 1 is a cylindrical sealed metal tank used to achieve the mixing reaction of wastewater and neutralizing agent; a first drive motor 3 is fixedly installed on its top surface by bolts. The first drive motor 3 is a high-speed rotary motor, and a main shaft 4 is installed at its output end through a coupling. The main shaft 4 extends vertically downward into the interior of the mixing chamber 1, and its bottom surface is rotatably connected to the bottom surface of the mixing chamber 1 through a rotary connecting seat. The rotary connecting seat has a built-in bearing to ensure stable rotation of the main shaft 4; an agitator blade 5 and a spreading disc 6 are installed on the surface of the main shaft 4 through a key connection. The spreading disc 6 is a circular metal disc located above the agitator blade 5 and is used to evenly spread the neutralizing agent.

[0021] A feeding box 14 is fixedly connected to the top surface of the mixing chamber 1 via a flange. The feeding box 14 is a metal box with an open top and a funnel-shaped bottom to facilitate the concentrated falling of the neutralizing agent. Its bottom surface is connected to the feeding pipe 22, which is used to transport the neutralizing agent. The filter tank 9 is a cylindrical metal box used to achieve solid-liquid separation. A second drive motor 12 is fixedly installed on its bottom surface via a motor base. The second drive motor 12 is a geared motor. A rotating drum 10 is fixedly installed at its output end via a coupling. The rotating drum 10 extends vertically upward into the interior of the filter tank 9. An inner cylinder 11 is nested inside the rotating drum 10. The inner cylinder 11 is used to trap solid sediment.

[0022] During the production of activated clay, the washing process generates wastewater containing sulfuric acid, which is transported to the mixing chamber 1 through the inlet pipe 2. Simultaneously, the servo motor 20 on the top surface of the feeding box 14 starts, driving the rotating rod 21 and the auger blades 23 on its surface to rotate, slowly conveying the calcium hydroxide powder stored inside the feeding box 14 to the feeding pipe 22, ultimately landing on the top surface of the spreading disc 6. The first drive motor 3 drives the main shaft 4 to rotate at high speed, synchronously driving the stirring blades 5 and the spreading disc 6 to rotate; the rotating spreading disc 6 uses centrifugal force to evenly spread the calcium hydroxide powder into the wastewater in the mixing chamber 1, avoiding localized accumulation of the neutralizing agent. The stirring blades 5 strongly stir the wastewater and calcium hydroxide powder, promoting thorough mixing and reaction, where sulfuric acid reacts with calcium hydroxide to form a solid precipitate of calcium sulfate.

[0023] After the reaction is complete, the gate valve 8 on the surface of the drain pipe 7 is opened, and the mixture containing calcium sulfate precipitate is injected into the inner cylinder 11 of the filter tank 9 through the drain pipe 7. The second drive motor 12 starts, driving the rotating drum 10 and the inner cylinder 11 to rotate at high speed. Using centrifugal force, the water in the mixture passes through the filter holes 16 of the inner cylinder 11 and the through holes 15 of the rotating drum 10, and enters the interlayer space of the filter tank 9, while the calcium sulfate precipitate is trapped in the inner cylinder 11, completing the wastewater purification. The purified wastewater flows back to the activated clay washing process along the circulation pipe 13 on the bottom of the filter tank 9 to continue participating in production, realizing the continuous recycling of water resources.

[0024] This device treats wastewater through an integrated process of "alkali neutralization - stirring and mixing - centrifugal filtration". The entire process requires no manual intervention, is highly efficient and rapid, and greatly improves work efficiency. The design of the feeding plate 6 ensures that the neutralizing agent is added evenly, improving the reaction effect. Compared with traditional filtration, centrifugal filtration is not only more efficient and faster, but also reduces filter pore clogging, further ensuring treatment efficiency. At the same time, it eliminates the tedious operation of manual feeding and improves the convenience of use.

[0025] Please refer to Figure 1 and Figure 2 One side of the mixing chamber 1 is connected to a water inlet pipe 2 via a flange. The other end of the water inlet pipe 2 is connected to the sulfuric acid-containing wastewater generated from the activated clay washing process, providing the device with a continuous supply of wastewater to be treated. The other side of the mixing chamber 1 is connected to a drain pipe 7 via a flange. The drain pipe 7 adopts a 90° bend design, with its other end extending to the top of the inner cylinder 11, ensuring that the mixed liquid can be accurately injected into the inner cylinder 11 and avoiding overflow. The bottom of the filter tank 9 is connected to a circulation pipe 13 via a flange. A water pump can be installed on the circulation pipe 13 to assist in the return of purified water. A slide valve 8 is installed on the surface of the drain pipe 7 via a flange. The slide valve 8 is controlled manually or electrically, allowing the staff to adjust the opening and closing of the drain pipe 7 according to the reaction progress and control the timing of the discharge of the mixed liquid.

[0026] Please refer to Figure 1 and Figure 4 The bottom surface of the feeding box 14 is connected to the feeding pipe 22 through the flange. The feeding pipe 22 is a metal rigid pipe that runs vertically downward through the pre-set through hole on the top surface of the mixing chamber 1 and extends to the top of the spreading plate 6 to ensure that the calcium hydroxide powder can fall accurately onto the spreading plate 6. The top surface of the feeding box 14 is fixedly installed with a servo motor 20 by bolts. The servo motor 20 can be precisely controlled by the controller to control the number of rotations, thereby adjusting the rotation angle of the rotating rod 21 and controlling the rotation stroke of the auger blade 23, ultimately achieving precise control of the feeding amount and avoiding waste or insufficient neutralizing agent.

[0027] A rotating rod 21 is mounted on the output end of the servo motor 20 via a coupling. The rotating rod 21 extends vertically downward into the inside of the feeding pipe 22. A screw conveyor blade 23 is welded to the inner side of the rotating rod 21. The edge of the screw conveyor blade 23 slides tightly against the inner wall of the feeding pipe 22, forming a sealed structure. This design effectively prevents calcium hydroxide powder from leaking from the feeding pipe 22 due to gravity when the screw conveyor blade 23 is not rotating, ensuring controllable feeding volume.

[0028] Please refer to Figure 3 and Figure 5 The rotating drum 10 has evenly spaced through holes 15, which are circular through holes, to allow the clear water after centrifugation to drain smoothly. The inner drum 11 has evenly spaced filter holes 16, which are also circular through holes. Both the filter holes 16 and the through holes 15 are densely and evenly spaced to ensure drainage efficiency. The pore diameter of the filter holes 16 is smaller than that of the through holes 15, and the pore diameter of the filter holes 16 is smaller than the particle size of the calcium sulfate precipitate. This allows the filter holes 16 to retain the calcium sulfate precipitate while allowing water to pass through smoothly, thus achieving solid-liquid separation. The larger pore diameter of the through holes 15 reduces the resistance when the clear water is discharged, thereby increasing the separation speed.

[0029] Please refer to Figure 1 and Figure 3 The top of the rotating drum 10 passes through a pre-set circular hole on the top surface of the filter tank 9 and is rotatably connected to the top surface of the filter tank 9 through a bearing 17. The bearing 17 can reduce the frictional resistance when the rotating drum 10 rotates, ensuring smooth rotation. The axes of the rotating drum 10, the filter tank 9 and the inner drum 11 coincide and are arranged coaxially. This structure makes the rotating drum 10 and the inner drum 11 evenly stressed when rotating, and will not cause eccentric swaying, further improving rotational stability and avoiding damage to the device or a decrease in separation effect due to vibration.

[0030] Please refer to Figure 3 and Figure 5The top edge of the rotating drum 10 is fixed with a column 19 by welding. The column 19 is a cylindrical metal rod. The top surface of the inner drum 11 has a corresponding insertion hole 18 on the column 19. The insertion hole 18 is a circular through hole, and there are two sets of insertion holes 18 and columns 19 arranged symmetrically. When there is a large amount of calcium sulfate precipitate trapped inside the inner drum 11, which affects the filtration effect, the operator can stop the operation of the device, pull the inner drum 11 upward, and let the column 19 come out of the insertion hole 18. Then the inner drum 11 can be removed from the rotating drum 10 to clean the internal precipitate.

[0031] After cleaning, align the insertion hole 18 of the inner cylinder 11 with the insertion post 19 of the rotating drum 10, and slowly lower the inner cylinder 11 so that the insertion post 19 passes through the insertion hole 18. The inner cylinder 11 will then be stably nested inside the rotating drum 10, completing the reinstallation. The device can then continue centrifugal filtration. This detachable design makes cleaning and maintenance simple and convenient, eliminating the need to disassemble the entire filter tank 9, significantly shortening maintenance time and further improving ease of use and work efficiency.

[0032] Please refer to Figure 1 and Figure 4 The top surface of the feeding box 14 is provided with a feeding port 24, which is a circular opening, so that the staff can regularly add calcium hydroxide powder into the feeding box 14. The inner wall of the feeding box 14 is finely polished and has a smooth and flat surface, which can reduce the frictional resistance between the calcium hydroxide powder and the box wall, facilitate the powder to move downward under the action of gravity, avoid the powder residue accumulation in the box, and ensure smooth feeding.

[0033] Please refer to Figure 1 and Figure 4 The feeding disc 6 is located above the stirring blade 5. This arrangement allows the calcium hydroxide powder to be initially mixed with the wastewater after being fed from the feeding disc 6, and then further improved by the strong stirring of the stirring blade 5. The top surface of the feeding disc 6 is also polished, which reduces the residue of calcium hydroxide powder on the feeding disc 6. At the same time, the centrifugal force allows the powder to fall more smoothly to all sides, ensuring uniform distribution.

[0034] Working principle: During the production of activated clay, sulfuric acid-containing wastewater enters the mixing chamber 1 through the inlet pipe 2. The servo motor 20 drives the rotating rod 21 and the auger blade 23 to rotate, conveying the calcium hydroxide powder in the feeding box 14 to the spreading plate 6. The first drive motor 3 drives the main shaft 4, the stirring blade 5 and the spreading plate 6 to rotate. The spreading plate 6 evenly spreads the powder, and the stirring blade 5 stirs the powder to react with the wastewater to form calcium sulfate precipitate.

[0035] When the slide valve 8 is opened, the mixed liquid is injected into the inner cylinder 11 of the filter tank 9 through the drain pipe 7; the second drive motor 12 drives the rotating drum 10 and the inner cylinder 11 to rotate, and the centrifugal force causes the clean water to pass through the filter hole 16 and the through hole 15 into the jacket of the filter tank 9, and return for reuse along the circulation pipe 13, while the calcium sulfate precipitate is retained in the inner cylinder 11.

[0036] When there is too much sediment in the inner cylinder 11, it is extracted and cleaned, and then connected to the insertion column 19 through the insertion hole 18; the whole device realizes continuous wastewater circulation and purification, uniform alkali addition, efficient filtration, and convenient maintenance, thereby improving the environmental protection and efficiency of activated clay production.
