Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a textile fabric printing and dyeing wastewater treatment device. Background Art

[0002] The printing and dyeing industry is an important part of the textile industry chain. In my country, the printing and dyeing industry is not only a major water user, but also a major water polluter. Therefore, the overall water pollution problem in the printing and dyeing industry cannot be underestimated. Printing and dyeing generally includes cotton textile printing and dyeing, linen textile printing and dyeing, wool textile printing and dyeing, etc. The material of wastewater is closely related to the raw materials, and mostly contains dyes, slurries, auxiliaries, various fibers, etc. Therefore, wastewater treatment requires multiple processes to be coordinated;

[0003] A Chinese patent with application number CN202410698169.2 discloses a textile printing and dyeing wastewater treatment and reuse system, including a filtering device, a water inlet device and a transfer bin. The filtering device includes a connecting plate, a No. 1 filter plate, a No. 2 filter plate, a No. 1 hinge, a No. 2 hinge, two inclined baffles and two telescopic columns. The left and right sides of the bottom of the connecting plate are rotatably connected to the No. 1 filter plate and the No. 2 filter plate through the No. 2 hinge and the No. 1 hinge respectively. A No. 1 groove is provided on the No. 1 filter plate and the No. 2 filter plate. The ends away from the No. 1 filter plate and the No. 2 filter plate are fixedly connected to the two telescopic columns respectively, and the ends away from each other of the two telescopic columns are fixedly connected to the two inclined baffles.

[0004] The above scheme uses the spring in the shock absorber to make the filter plate vibrate so as to prevent impurities from clogging the filter plate. However, due to the flushing of wastewater, the fluff fiber impurities in the wastewater may be intercepted by the filter screen and may adhere to the filter plate in a complicated way due to their slender and entangled characteristics, making it difficult to clean. The adhesion cannot be avoided by shaking alone, and the vibration frequency of the spring of the shock absorber after the collision is low, which cannot shake off most of the impurities on the filter plate, so the filter plate will still be blocked. In addition, the above form cleans impurities by swinging left and right. However, since the filtering operation is carried out together with the slag removal operation, some wastewater and impurities will be brought out when the filter plate shakes, and the solid-liquid separation operation cannot be effectively performed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a textile fabric printing and dyeing wastewater treatment device, which solves the problems of incomplete solid-liquid separation and poor filter plate cleaning effect of the existing equipment.

[0026] Further optimized, the driving member includes a rotating shaft, a working motor and a gear set,

[0027] There are two rotating shafts, which are respectively connected to two filter plates;

[0028] The working motor is mounted on the outside of the bearing frame and connected to one of the rotating shafts;

[0029] The gear set comprises a first gear and a second gear which are meshed with each other. The first gear and the second gear are respectively sleeved on two rotating shafts to drive the two filter plates to flip or reset.

DETAILED DESCRIPTION

[0048] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0049] Example 1

[0050] In the prior art, the filter plate 42 is vibrated by the spring in the shock absorber to prevent impurities from clogging the filter plate 42. However, due to the flushing of wastewater, fiber impurities in the wastewater will adhere to the filter plate 42, and clogging cannot be avoided by shaking alone, thereby affecting subsequent filtering operations.

[0051] To solve the above defects, this embodiment discloses a textile fabric printing and dyeing wastewater treatment device, such as Figure 1-4As shown, including:

[0052] The liquid inlet bin 1 has a liquid inlet on the top, and its bottom is connected to a liquid inlet cylinder 2; a liquid inlet bucket is connected above the liquid inlet, and the liquid inlet bucket is in the shape of a truncated cone with a wide top and a narrow bottom, thereby increasing the area for wastewater to enter the liquid inlet bin 1. The bottom of the liquid inlet bin 1 is moved inward to form a water outlet and is connected to the liquid inlet cylinder 2. It can be known that the outer side of the liquid inlet bin 1 is stably supported by a support frame, thereby ensuring that the liquid inlet bin 1 is stably suspended.

[0053] The collecting unit 3 is located below the liquid inlet bin 1 and includes a wastewater collecting chamber 31 and a waste residue collecting chamber 32 arranged in parallel; specifically, after being processed, the wastewater and waste residue are separated and collected by the wastewater collecting chamber 31 and the waste residue collecting chamber 32 respectively.

[0054] The filter unit 4 is arranged between the liquid inlet cylinder 2 and the collection unit 3, and the filter unit 4 slides to align with the wastewater collection chamber 31 or the waste residue collection chamber 32 to perform solid-liquid separation and slag removal; specifically, the filter unit 4 is slidably arranged on the top of the wastewater collection chamber 31 and the waste residue collection chamber 32, so as to facilitate slag removal and solid-liquid separation.

[0055] The cleaning assembly 5 is rotatably mounted on the liquid inlet bin 1, and is used to extend into the filter unit 4 for cleaning or extend out of the filter unit 4 to seal the bottom of the liquid inlet bin 1. Specifically, on the one hand, the cleaning assembly 5 is used to clean the impurities in the filter unit 4 to reduce the occurrence of adhesion to block the filter plate 42, and on the other hand, the cleaning assembly 5 extends out of the filter unit 4 to ensure the normal movement of the filter unit 4, and at the same time seals the bottom of the liquid inlet bin 1 to prevent wastewater from falling into the wastewater collection chamber 31 after leaving the filter unit 4.

[0056] The working process in this embodiment is:

[0057] During solid-liquid separation, the filter unit 4 is connected to the liquid inlet cylinder 2 and is located directly above the wastewater collecting chamber 31. The wastewater enters the wastewater collecting chamber 31 after being filtered by the filter unit 4. At the same time, the cleaning component 5 extends into the filter unit 4 to sweep impurities aside, thereby avoiding clogging of the filter plate 42.

[0058] When pouring the residue, first, the cleaning assembly 5 extends back to the liquid inlet cylinder 2 and simultaneously blocks the liquid inlet bin 1. At this time, the liquid inlet bin 1 forms a storage chamber for temporarily storing the wastewater to be treated. On the one hand, it does not affect the normal entry of the wastewater to ensure the continuous treatment of the wastewater. On the other hand, the untreated wastewater will not enter the wastewater collection chamber 31, ensuring the effective solid-liquid separation. After that, the filter unit 4 slides to the waste residue collection chamber 32, and the filter unit 4 returns to the bottom of the liquid inlet cylinder 2 after the residue pouring operation.

[0059] Furthermore, the cleaning assembly 5 includes a first telescopic rod 51, a blocking block 52, a rotating rod 53 and a rotating brush 54.

[0060] The first telescopic rod 51 is disposed on the liquid inlet bin 1 ; specifically, the first telescopic rod 51 is located in the inner middle portion of the liquid inlet bin 1 , and the first telescopic rod 51 provides support and power for the extension of the rotating brush 54 .

[0061] The blocking block 52 is installed at the telescopic end of the first telescopic rod 51 and just matches and blocks the bottom of the liquid inlet bin 1; the specific size of the blocking block 52 matches the bottom opening of the liquid inlet bin 1. When the first telescopic rod 51 is extended, the blocking block 52 is located below the bottom opening of the liquid inlet bin 1, and at this time, the wastewater flows into the filter unit 4 through the liquid inlet cylinder 2; when the first telescopic rod 51 is retracted, the blocking block 52 moves upward to block the bottom opening of the liquid inlet bin 1.

[0062] The rotating rod 53 is rotatably mounted at the bottom of the blocking block 52; specifically, a protective groove is provided at the bottom of the blocking block 52, a driving motor is provided in the protective groove, and the driving motor is connected to the rotating rod 53, thereby driving the rotating rod 53 and the rotating brush 54 to rotate.

[0063] There are multiple rotating brushes 54, which are circumferentially arranged on the rotating rod 53 to abut against the surface of the filter plate 42. Specifically, the rotating brush 54 abuts against the surface of the filter plate 42 and moves on the filter plate 42 to clean and avoid clogging caused by impurities adhering.

[0064] Specifically, the specific working process of the cleaning component 5 is:

[0065] The first telescopic rod 51 drives the blocking block 52 and the rotating brush 54 to move downward at the same time, and the blocking block 52 leaves the bottom opening of the liquid inlet bin 1, and the rotating brush 54 extends into the filter unit 4. The wastewater passes through the liquid inlet bin 1, and after being buffered by the blocking block 52, it flows into the liquid inlet cylinder 2 from the gap between the blocking block 52 and the liquid inlet bin 1, and finally enters the filter unit 4 for filtration. At this time, the rotating rod 53 rotates under the drive of the driving motor, driving the rotating brush 54 to clean the filter plate 42 to avoid clogging of the filter plate 42.

[0066] Afterwards, the first telescopic rod 51 drives the blocking block 52 and the rotating brush 54 to move upward at the same time. At this time, the blocking block 52 cooperates with the bottom opening of the liquid inlet bin 1 to block the blocking block 52, and the rotating brush 54 leaves the filter unit 4. On the one hand, the departure of the rotating brush 54 facilitates the movement of the filter unit 4, and on the other hand, the blocking block 52 blocks the bottom opening of the liquid inlet bin 1. Therefore, after the filter unit 4 leaves, the wastewater stops passing through the liquid inlet cylinder 2 and can be temporarily stored in the liquid inlet bin 1, thereby ensuring the normal treatment of the wastewater.

[0067] It can be known that, compared with the prior art that uses collision to shake the filter plate 42, the spring in the shock absorber shakes less frequently under the shock absorption effect, and there is a situation where fiber impurities adhering to the filter plate 42 cannot be shaken off. The cleaning component 5 can better clean the impurities adhering to the filter unit 4, and at the same time reduce the blockage of the filter plate 42, and can automatically extend into and out of the filter unit 4 without affecting the normal movement of the filter unit 4.

[0068] Furthermore, in order to ensure that the wastewater to be treated can fall effectively, it is configured that: the blocking block 52 is a conical structure. Specifically, the four sides of the blocking block 52 are inclined downward, and the wastewater is buffered to a certain extent when passing through the blocking block 52, and then slides down through the inclined surface of the blocking block 52, thereby ensuring that the wastewater can flow into the filter unit 4 gently and completely.

[0069] Further, if Figure 1 and Figure 3 As shown, the filter unit 4 includes a carrier frame 41, a filter plate 42 and a drive member 43.

[0070] The carrying frame 41 is used to communicate with the liquid inlet cylinder 2; the size of the carrying frame 41 is slightly larger than the liquid inlet cylinder 2, so as to ensure that the wastewater completely enters the carrying frame 41 for filtering treatment.

[0071] There are two filter plates 42 , which are rotatably arranged in the middle of the supporting frame 41 ; specifically, the filter plates 42 are used to separate fiber impurities and wastewater, and the filtered impurities are temporarily stored in the supporting frame 41 , and the wastewater enters the wastewater collecting chamber 31 .

[0072] The driving member 43 is disposed outside the carrier frame 41 and is connected to the two filter plates 42 to drive the two filter plates 42 to flip or lay flat. The driving member 43 includes a rotating shaft 431, a working motor 432 and a gear set.

[0073] There are two rotating shafts 431, which are respectively connected to two filter plates 42;

[0074] The working motor 432 is installed outside the carrying frame 41 and connected to one of the rotating shafts 431;

[0075] The gear set includes a first gear 433 and a second gear 434 that are meshed. The first gear 433 and the second gear 434 are respectively sleeved on two rotating shafts 431 to drive the two filter plates 42 to flip or reset.

[0076] The function of the driving member 43 is as follows: when the carrying frame 41 moves to the position directly above the waste collection chamber 32, the driving member 43 works to flip the two filter plates 42. Specifically, the filter plate 42 on the left flips clockwise, and the filter plate 42 on the right flips counterclockwise, so that the fiber impurities on the two filter plates 42 are leaked into the waste collection chamber 32. The specific working process is as follows: start the working motor 432, one of which rotates

[0077] The shaft rotates, and under the meshing of the first gear 433 and the second gear 434, the two rotating shafts 431 rotate and respectively drive the two filter plates 42 to flip over to complete the slag discharge operation. In addition, when the friction coefficient between the first gear 433 and the second gear 434 is large and the working motor 432 is a self-locking motor, the two rotating shafts 431 will not rotate after the working motor 432 stops working. Therefore, when performing the filtering operation, the two filter plates 42 will not flip over easily.

[0078] When the height of the waste collection chamber 32 is smaller than its width, by setting two filter plates 42, the effect achieved is: the two filter plates 42 are still in the supporting frame 41 after being flipped, and will not affect the normal collection of the waste collection chamber 32. At the same time, the rotating shaft 431 is set in the middle of the filter plate 42, which can better provide support force for the filter plate 42.

[0079] It can be known that the cleaning component 5 can effectively reduce the adhesion of fiber impurities to the filter plate 42 after cleaning, so in the subsequent slag disposal process, the impurities can be better processed by flipping the filter plate 42.

[0080] Example 2

[0081] Since there is always a certain gap between the blocking block 52 and the bottom of the liquid inlet tank 1, such as Figure 1 and Figure 2 As shown, in order to further ensure the blocking effect of the blocking block 52 , it is configured as follows: fasteners 6 are provided on the four sides of the liquid inlet cylinder 2 for abutting against the four sides of the blocking block 52 .

[0082] Furthermore, the fastener 6 includes an abutment block 61 and a first spring 62.

[0083] The abutment block 61 is slidably arranged on the liquid inlet cylinder 2; the abutment block 61 is a wedge-shaped triangular block protruding outward, and the wedge-shaped triangular block gradually expands outward from top to bottom, so that the four abutment blocks 61 are tightly fitted with the blocking block 52 to avoid wastewater leakage.

[0084] The first spring 62 is disposed between the abutment block 61 and the liquid inlet cylinder 2 .

[0085] When the first telescopic rod 51 drives the blocking block 52 to move upward, the blocking block 52 abuts against the four abutting blocks 61 , and the blocking block 52 and the four abutting blocks 61 are tightly connected to avoid the trouble caused by leakage of waste water.

[0086] Example 3

[0087] In order to ensure the stable movement of the carrying frame 41, the present invention provides another embodiment, such as Figure 4 As shown, the bottom of the carrier frame 41 is provided with guide wheels 7, and the tops of the wastewater collection chamber 31 and the waste residue collection chamber 32 are provided with guide rails 8 for the guide wheels 7 to slide. In this embodiment, four guide wheels 7 are provided at the bottom of the carrier frame 41, and guide rails 8 are provided on both sides of the wastewater collection chamber 31 and the waste residue collection chamber 32, and the four guide wheels 7 slide on two guide rails 8 in a directional manner.

[0088] Example 4

[0089] In the prior art, operators usually add drugs to the wastewater after filtration to help purify the wastewater and perform re-flocculation treatment. However, the amount of added drugs often needs to be controlled. If the amount of drug added is too little, the best fusion effect may not be achieved; if the amount of drug added is too much, it may cause waste.

[0090] Based on this, Figure 1 and Figure 4 As shown, in this embodiment, a feeding assembly 9 is arranged on the top of the wastewater collection chamber 31 , and the feeding assembly 9 includes a feeding cylinder 91 , an operating rod 92 , a second spring 93 and a stopper 94 .

[0091] The feeding cylinder 91 is arranged at the top of the wastewater collecting chamber 31 and is connected to the wastewater collecting chamber 31. Specifically, the feeding cylinder 91 is engraved with a scale (not shown in the figure), and the operator can manually control the amount of medicine added. When adding medicine, the amount of medicine added is reflected according to the change of the amount of medicine on the feeding cylinder 91.

[0092] The operating rod 92 is slidably mounted on the feeding cylinder 91;

[0093] The second spring 93 is sleeved on the operating rod 92 and installed between the operating rod 92 and the top of the feeding cylinder 91; specifically, the operating rod 92 is T-shaped, one end of the second spring 93 is fixedly connected to the operating rod 92, and the other end of the second spring 93 is fixedly connected to the top of the feeding cylinder 91.

[0094] The stopper 94 is disposed at one end of the operating rod 92 and is used to open or close the connection between the wastewater collecting chamber 31 and the feeding cylinder 91 .

[0095] The specific working form is: by pressing the operating rod 92, the operating rod 92 drives the stopper 94 to move downward together, so that the stopper 94 leaves the bottom position of the feeding cylinder 91, and the medicine enters the wastewater collection chamber 31. At this time, the second spring 93 is in a compressed state.

[0096] However, when the operating rod 92 does not apply external force, under the elastic force of the second spring 93, the second spring 93 drives the operating rod 92 to reset upward, and the stopper 94 moves upward to close the connection between the wastewater collection chamber 31 and the feeding cylinder 91.

[0097] It should be noted that the weight of the medicine in the feeding barrel 91 is less than the elastic force of the second spring 93. In the initial state, the elastic force of the second spring 93 is sufficient to support the block 94 to close the connection between the wastewater collection chamber 31 and the feeding barrel 91. Only when external force is applied will the block 94 leave and the medicine can enter the wastewater collection chamber 31.

[0098] In order to fully blend the medicine with the treated wastewater, it is configured as follows: a stirring mechanism is provided in the wastewater collection chamber 31. Specifically, the stirring mechanism includes a stirring blade, a stirring shaft and a first motor, wherein the stirring shaft is connected to the first motor, and the stirring blade is circumferentially arranged on the stirring shaft. Driven by the first motor, the stirring shaft drives the stirring blade to rotate in the wastewater collection chamber 31, so that the medicine is more evenly blended into the water.

[0099] In addition, a waste box 10 is slidably arranged in the waste collection chamber. The replaceable waste box 10 ensures continuous recycling of waste materials, and the waste box 10 can be replaced during the filtering and separation time, thereby ensuring continuous wastewater treatment.

[0100] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
