Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to wastewater treatment equipment for the production and preparation of iron oxide pigments. Background Art

[0002] Iron oxide is the largest colored inorganic pigment and the second largest inorganic pigment after titanium dioxide. Iron oxide pigments mainly include four categories of iron oxide red, yellow, black and brown, which are based on iron oxide. Iron oxide yellow, also known as hydroxy iron oxide, will dehydrate and decompose at about 177 degrees Celsius to become red. Therefore, the application of ordinary iron oxide yellow pigment in high temperature occasions such as plastic processing and baking coatings is limited. The surface coating of iron oxide yellow pigment can improve its heat resistance, thereby expanding the application field of iron oxide yellow pigment. Its preparation process mainly adopts wet method, which can make the pigment preparation more delicate.

[0003] In the production process of iron oxide pigments, a large amount of wastewater is usually generated. The wastewater contains a large amount of pollutants and needs to be treated before it can be discharged.

[0004] In the existing wastewater treatment device for the production and preparation of iron oxide pigments, alkaline substances are usually added to the wastewater to adjust the pH value and flocculants are added to make the pollutants form flocs during the treatment process, so as to facilitate the purification of the wastewater. However, after the corresponding alkaline substances or flocculants are added, the wastewater is usually stirred by a unidirectional rotating fixed blade, and it is difficult for the unidirectional rotating fixed blade to quickly and evenly stir the wastewater and the alkaline substances or flocculants during the rotation process. Pollutants may still remain in the purified wastewater, which increases the hidden danger of wastewater discharge. Moreover, in the process of adding alkaline substances or flocculants, the materials added are mostly added manually by staff, and subjective measurement of materials is prone to errors, which also increases the workload of staff.

Alkaline substances, such as sodium hydroxide, can be added to the wastewater first. The mixing component 3 can quickly adjust the pH value of the wastewater by driving the sodium hydroxide and the wastewater to mix quickly. After the pH value of the wastewater is adjusted to an appropriate value, a flocculant is added to the wastewater. The mixing component 3 drives the flocculant and the wastewater to mix quickly so that the pollutants in the wastewater quickly form flocs. The flocs can be filtered through the filter screen 6, thereby achieving wastewater purification. The valve 104 is opened to make the liquid outlet pipe 103 in a conducting state, so that the purified wastewater can be discharged, which is convenient for subsequent wastewater treatment. It has the advantages of fast and uniform mixing, efficient purification, and flexibility. The bracket assembly 7 comprises a collar 701 arranged on the outside of the treatment tube 1, and a plurality of columns 702 are distributed circumferentially on the outside of the collar 701. The end of the column 702 away from the collar 701 is connected to a bottom plate 703. Through the cooperation of the collar 701, the column 702 and the bottom plate 703, the treatment tube 1 can be stably supported. A detection port 102 is also provided on the side wall of the treatment tube 1. Through the detection port 102, it is convenient for the staff to detect the pH value of the wastewater after the addition of alkaline substances. When the pH value of the wastewater after adjustment is still acidic, alkaline substances will continue to be added to the wastewater. When the pH value of the wastewater after adjustment reaches a suitable value, flocculant can be added to the wastewater, which is convenient for treating pollutants in the wastewater.

[0068] In one embodiment of the present invention, see Figure 2-4 The mixing assembly 3 includes a rotating rod 302 rotatably arranged on the top cover 2, one end of the rotating rod 302 is connected to a stepping motor 301 arranged on the top cover 2, and the other end of the rotating rod 302 is connected to a gear 303 located inside the processing cylinder 1.

Through the connection of the connecting rod 1 308, the corresponding stirring plate 1 307 can be synchronously rotated up or down. In the embodiment, at least three stirring plates 307 are provided on the stirring group, and a plurality of spoiler grooves 3071 are distributed on the stirring plate 307. The spoiler grooves 3071 can be set as long strip grooves, wavy grooves or V-shaped grooves. The spoiler grooves 3071 are set to facilitate the spoiler flow of the wastewater, thereby avoiding the problem that the wastewater and the additive may not be fully mixed due to the unidirectional stirring of the wastewater. A plurality of cleaning brushes 8 are circumferentially distributed on one end of the rotating rod 305 close to the filter screen 6, which can clean the flocs accumulated on the filter screen 6 to avoid the flocs clogging the filtering channel of the filter screen 6, thereby facilitating the continuous purification of the wastewater.

[0072] In this embodiment, when the stepper motor 301 drives the rotating rod 1 302 to rotate in the forward direction, at this time, the one-way transmission member 401 does not abut against the inner gear ring 402, the one-way transmission member 401 does not drive the inner gear ring 402 to rotate, the positions of the gear 3 403, the movable cylinder 405 and the lifting cylinder 407 are fixed, and the angle between the stirring plate 1 307 and the rotating rod 2 305 is at the minimum value. The stirring plate 1 307 can stir the wastewater near the rotating rod 2 305. When the stepper motor 3 When the rotating rod 1 302 is driven to rotate in the reverse direction by the gear 1 303 and the gear 2 304, the rotating rod 1 302 drives the rotating rod 2 305 to rotate synchronously. The rotating rod 2 305 drives the stirring plate 1 307 to rotate through the connection of the hinge seat 306. At the same time, the rotating rod 1 302 drives the one-way transmission member 401 to rotate synchronously. The ratchet 4013 provided on the one-way transmission member 401 abuts against the inner gear ring 402.

The connecting rod two 410 drives the stirring plate one 307 to swing back and forth around the hinge seat 306 synchronously by connecting with the stirring plate one 307 and rotating cooperation between the stirring plate one 307 and the hinge seat 306. The rotation range of the stirring plate one 307 can be adjusted, and the wastewater and additives in the treatment cylinder 1 can be efficiently and evenly mixed, avoiding the problem of uneven mixing caused by the fixed rotation angle of the stirring plate one 307.

[0073] In one embodiment of the present invention, see Figure 3 , Figure 5-7 and Figure 9-10The unloading assembly 5 includes two storage boxes 508 arranged above the top cover 2, and the two storage boxes 508 are respectively filled with powdered alkaline substances and powdered flocculants. The bottom of the storage box 508 is connected to a guide pipe 509, and the bottom end of the guide pipe 509 corresponds to the through hole 2 511 arranged on the top cover 2. The guide pipe 509 is provided with a solenoid valve 510. A rotating rod 4 501 is rotatably arranged in the storage box 508, and a plurality of stirring plates 2 502 are arranged on the rotating rod 4 501 located in the storage box 508. One end of the rotating rod 4 501 passes through the storage box 508 and the top cover 2 and is connected to the corresponding gear 3 4 03 is connected, the gear three 403 is provided with a through hole one 503 which is movably matched with the through hole two 511, the gear three 403 is provided with a storage barrel 504 corresponding to the through hole one 503 on the side close to the processing barrel 1, a horizontal plate 505 is provided between the processing barrel 1 and the top cover 2, the horizontal plate 505 is connected to the top cover 2 through a mounting plate 507, the side of the horizontal plate 505 close to the top cover 2 is movably fitted with an end of the storage barrel 504 away from the gear three 403, the horizontal plate 505 is provided with a feeding trough 506 which is located on the side of the rotating rod four 501 away from the through hole two 511, and the feeding trough 506 is movably corresponding to the storage barrel 504.

[0074] In this embodiment, in the initial state, the two solenoid valves 510 are in the closed state. At this time, the storage barrel 504 corresponds to the feeding trough 506, the movable barrel 405, the rotating barrel 406 and the lifting barrel 407 are at the highest point, the angle between the stirring plate 1 307 and the rotating rod 2 305 is at the maximum value, the stepping motor 301 drives the inner gear ring 402 to rotate through the one-way transmission member 401, and the inner gear ring 402 drives the storage barrel 504 and the rotating rod 3 404 to rotate synchronously by meshing with the gear 3 403;

[0075] In the process of the storage barrel 504 rotating to the position matched with the through hole 2 511, the rotating rod 3 404 drives the rotating barrel 406 to move downward by connecting the oblique annular groove 4041 with the sliding column 1 4051 and the movable barrel 405 with the rotating barrel 406. The rotating barrel 406 drives the stirring plate 1 307 to rotate downward by the rotation connection with the lifting barrel 407 and the sliding cooperation between the guide slide plate 408 and the sliding column 2 409, which can reduce the rotation range of the stirring plate 1 307. When the corresponding alkaline substance or flocculant is added, the corresponding solenoid valve 510 is opened, and the guide tube 509 is in a conducting state. When the storage barrel 504 rotates to a position aligned with the second through hole 511, the corresponding alkaline substance or flocculant will pass through the guide tube 509 under its own gravity and sequentially pass through the second through hole 511 and the first through hole 503 and fall into the storage barrel 504. The bottom of the storage barrel 504 can form a temporary storage space for the powdered alkaline substance or powdered flocculant by cooperating with the horizontal plate 505.

[0076] When the material storage barrel 504 rotates to a position matched with the feeding trough 506, the rotating rod 3 404 drives the rotating drum 406 to move upward by connecting the oblique annular groove 4041 with the sliding column 1 4051 and the movable barrel 405 with the rotating drum 406. The rotating drum 406 drives the stirring plate 1 307 to rotate upward by connecting with the lifting barrel 407 and slidingly cooperating with the guide slide plate 408 and the sliding column 2 409, so that the rotation range of the stirring plate 1 307 can be expanded. When the material storage barrel 504 rotates to a position matched with the feeding trough 506, the alkaline substance or flocculant in the material storage barrel 504 will fall into the treatment barrel 1 through the feeding trough 506 and come into contact with the wastewater. At this time, the angle between the stirring plate 1 307 and the rotating rod 2 305 is at its maximum value, which is convenient for quickly stirring the wastewater and the alkaline substance or flocculant, thereby improving the wastewater purification efficiency.

[0077] After the alkaline substance or flocculant is added, the corresponding electromagnetic valve 510 is closed. At this time, the stepper motor 301 still drives the one-way transmission member 401 to rotate in the opposite direction, so that the stirring plate 307 can swing back and forth up and down, so as to evenly stir the wastewater and the alkaline substance or flocculant, thereby improving the purification efficiency of the wastewater.

[0078] Among them, a portion of material can be temporarily stored inside the temporary storage space. When adding alkaline substances or flocculants, the corresponding number of materials can be added according to the adding needs by opening the corresponding solenoid valve 510 and circulating the temporary storage space, so as to achieve accurate feeding of alkaline substances or flocculants and avoid waste caused by excessive feeding. The feeding trough 506 can be set as an arc-shaped strip groove, which can effectively prolong the conduction time at the bottom of the storage box 508 and facilitate the complete discharge of the materials inside the storage box 508. The gear three 403 drives the rotating rod four 501 to rotate, and the rotating rod four 501 drives the stirring plate two 502 to rotate to stir the powdered alkaline substances or powdered flocculants in the storage box 508. The coagulant is stirred to avoid the alkaline substance or flocculant from caking during long-term storage, which is convenient for the discharge of the alkaline substance or flocculant. The top of the storage box 508 is provided with a screw cover to facilitate the input of materials. The storage box 508 is connected to the mounting frame 201 arranged on the top cover 2. The two storage boxes 508 can be stably supported by the mounting frame 201. The staff adjusts the angle of the stirring plate 307 by adjusting the reverse driving time of the stepper motor 301 to meet the use requirements of different stirring effects. When the stepper motor 301 is driven forward, the adjustment component 4 and the unloading component 5 do not work, which can effectively reduce wear and extend the service life.

[0079] Specific:

[0080] Wastewater is introduced into the treatment tube 1 through the liquid inlet pipe 101, and the stepper motor 301 drives the rotating rod 1 302 to rotate, and the rotating rod 1 302 drives the gear 1 303 to rotate, and the gear 1 303 drives the rotating rod 2 305 to rotate by meshing with the gear 2 304, and the rotating rod 2 305 drives the stirring plate 1 307 to rotate through the hinge seat 306;

[0081] In the process of the storage barrel 504 rotating to the position matched with the through hole 2 511, the rotating rod 3 404 drives the rotating drum 406 to move downward by connecting the oblique annular groove 4041 with the sliding column 1 4051 and the movable cylinder 405 with the rotating drum 406. The rotating drum 406 drives the stirring plate 1 307 to rotate downward by the rotation connection with the lifting cylinder 407 and the sliding cooperation between the guide slide plate 408 and the sliding column 2 409. The rotation range of the stirring plate 1 307 can be reduced. When it is necessary to add the corresponding alkaline substance or flocculant into the wastewater , open the corresponding solenoid valve 510, the guide tube 509 is in a conducting state, when the storage barrel 504 rotates to a position aligned with the second through hole 511, the corresponding alkaline substance or flocculant will pass through the guide tube 509 under its own gravity and sequentially pass through the second through hole 511 and the first through hole 503 and fall into the first through hole 503, and the bottom of the first through hole 503 can temporarily form a space for storing powdered alkaline substances or powdered flocculants by cooperating with the horizontal plate 505, so as to facilitate the transfer of the position of the powdered alkaline substances or powdered flocculants;

[0082] When the storage barrel 504 rotates to a position matched with the feeding trough 506, the rotating rod 3 404 drives the rotating barrel 406 to move upward by connecting the oblique annular groove 4041 with the sliding column 1 4051 and the movable barrel 405 with the rotating barrel 406. The rotating barrel 406 drives the stirring plate 1 307 to rotate upward by connecting with the lifting barrel 407 and slidingly cooperating with the guide slide plate 408 and the sliding column 2 409, so that the rotation range of the stirring plate 1 307 can be expanded. When the storage barrel 504 rotates to a position matched with the feeding trough 506, the alkaline substance or flocculant in the storage barrel 504 will fall into the treatment barrel 1 through the feeding trough 506 and come into contact with the wastewater. At this time, the angle between the stirring plate 1 307 and the rotating rod 2 305 is at the maximum value, so that the wastewater and the alkaline substance or flocculant are quickly stirred.

[0083] After the alkaline substance or flocculant is added, the corresponding electromagnetic valve 510 is closed. At this time, the stepper motor 301 still drives the one-way transmission member 401 to rotate in the opposite direction, so as to realize the up and down reciprocating swing of the stirring plate 1 307, and evenly stir the wastewater and the alkaline substance or flocculant.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
