Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for textile fabric dyeing and printing. Background Technology

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

[0003] Chinese patent application number CN202410698169.2 discloses a wastewater treatment and reuse system for textile printing and dyeing, including a filtration device, a water inlet device, and a transfer chamber. The filtration device includes a connecting plate, a first filter plate, a second filter plate, a first hinge, a second hinge, two inclined baffles, and two telescopic columns. The first filter plate and the second filter plate are rotatably connected to the left and right sides of the bottom of the connecting plate through the second hinge and the first hinge, respectively. A groove is opened on both the first filter plate and the second filter plate. The ends of the first filter plate and the second filter plate that are away from each other are fixedly connected to the two telescopic columns. The ends of the two telescopic columns that are away from each other are fixedly connected to the two inclined baffles.

[0004] The above-mentioned solution uses springs within the shock absorber to vibrate the filter plate, thus preventing impurities from clogging it. However, due to the scouring effect of wastewater, lint and fibrous impurities in the wastewater, after being intercepted by the filter screen, may adhere to the filter plate in a complex manner due to their long and tangled nature, making cleaning difficult. Vibration alone cannot prevent this adhesion, and the low vibration frequency of the shock absorber's spring after impact is insufficient to shake off most of the impurities from the filter plate, resulting in continued clogging. Furthermore, while the above method uses left-right swaying to clean impurities, since filtration and sludge removal are performed simultaneously, the vibration of the filter plate carries away some wastewater and impurities, hindering effective solid-liquid separation. Summary of the Invention

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

[0006] This invention is achieved through the following technical solution:

[0007] A wastewater treatment device for textile dyeing and printing includes:

[0008] The liquid inlet chamber has a liquid inlet at the top and a liquid inlet cylinder at the bottom;

[0009] The collection unit, located below the liquid inlet chamber, includes wastewater collection chambers and waste residue collection chambers arranged side by side;

[0010] The filter unit is located between the liquid inlet cylinder and the collection unit. The filter unit slides to align with the wastewater collection chamber or the waste residue collection chamber to perform solid-liquid separation and sludge removal.

[0011] The cleaning assembly is rotatably mounted on the inlet chamber and is used to extend into the filter unit for cleaning or extend out of the filter unit to seal the bottom of the inlet chamber.

[0012] Further optimization is implemented to ensure the normal operation of the cleaning assembly and the normal movement of the filter unit, and to ensure the normal entry of wastewater after the filter unit moves. The cleaning assembly is configured as follows: it includes a first telescopic rod, a sealing block, a rotating rod, and a rotating brush.

[0013] The first telescopic rod is installed on the liquid inlet chamber;

[0014] The sealing block is installed at the telescopic end of the first telescopic rod and fits perfectly with the bottom of the liquid inlet chamber to seal it.

[0015] The rotating rod is rotatably mounted at the bottom of the sealing block;

[0016] There are multiple rotating brushes, which are arranged circumferentially on a rotating rod to abut against the surface of the filter plate.

[0017] Further optimization involves making the sealing block a conical structure.

[0018] Further optimization involves fasteners on all four sides of the inlet cylinder to abut against the four sides of the sealing block.

[0019] Further optimization involves the fastener comprising an abutment block and a first spring.

[0020] The abutment block is slidably mounted on the liquid inlet cylinder;

[0021] The first spring is disposed between the abutment block and the liquid inlet cylinder.

[0022] Further optimization involves the filter unit comprising a support frame, a filter plate, and a driving component.

[0023] The support frame is used to communicate with the liquid inlet cylinder;

[0024] There are two filter plates, which are rotatably arranged in the middle of the support frame;

[0025] The driving component is located outside the support frame and is connected to the two filter plates, used to drive the two filter plates to flip or lay flat.

[0026] Further optimization involves adding a rotating shaft, a working motor, and a gear set to the drive component.

[0027] There are two rotating shafts, each connected to one of the two filter plates.

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

[0029] The gear set includes a meshing first gear and a second gear, which are respectively mounted on two rotating shafts to drive the two filter plates to flip or reset.

[0030] Further optimization involves providing guide wheels at the bottom of the support frame, and providing guide rails at the top of both the wastewater collection chamber and the waste residue collection chamber for the guide wheels to slide.

[0031] Further optimization involves providing a feeding assembly at the top of the wastewater collection chamber, which includes a feeding cylinder, an operating rod, a second spring, and a stop block.

[0032] The feeding cylinder is arranged at the top of the wastewater collection chamber and is connected to the wastewater collection chamber;

[0033] The operating lever is slidably mounted on the feeding cylinder;

[0034] The second spring is sleeved on the operating rod and installed between the operating rod and the top of the feeding cylinder;

[0035] The stop block is located at one end of the operating lever and is used to open or close the connection between the wastewater collection chamber and the feeding cylinder.

[0036] Further optimization involves a waste bin being slidably arranged inside the waste collection chamber.

[0037] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0038] 1. The solid-liquid separation operation and slag disposal are separated by the sliding of the filter unit in the wastewater collection chamber and the waste residue collection chamber. Combined with the cleaning component, the adhesion of the filter plate is reduced to facilitate the subsequent slag disposal, while avoiding the clogging of the filter plate.

[0039] 2. By setting up a cleaning component, compared with the shock absorber of the existing technology that causes collision and shaking, the cleaning component can better clean the impurities adhering to the filter unit, while reducing the clogging of the filter plate, and can automatically extend into and out of the filter unit without affecting the normal movement of the filter unit.

[0040] 3. While the cleaning component extends out of the filter unit, it seals the bottom of the inlet chamber, forming a storage cavity for temporarily storing wastewater to be treated. On the one hand, this does not affect the normal entry of wastewater and ensures the continuous operation of wastewater treatment; on the other hand, untreated wastewater will not enter the wastewater collection cavity, ensuring the effective solid-liquid separation.

[0041] To more clearly illustrate the technical solutions of the exemplary embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly described below. It should be understood that the following drawings only show some embodiments of the present invention and should not be considered as a limitation of the scope.

Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention 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 shaken by the spring in the shock absorber to prevent impurities from clogging the filter plate 42. However, due to the flushing of wastewater, fibrous impurities in the wastewater may adhere to the filter plate 42. Shaking alone cannot prevent clogging and thus affect subsequent filtration operations.

[0051] To address the aforementioned shortcomings, this embodiment discloses a wastewater treatment device for textile fabric dyeing and printing, such as... Figure 1-4As shown, it includes:

[0052] The inlet chamber 1 has an inlet at the top and an inlet cylinder 2 connected to its bottom. Above the inlet is an inlet hopper, which is a frustum-shaped container wider at the top and narrower at the bottom, increasing the area for wastewater to enter the inlet chamber 1. The bottom of the inlet chamber 1 converges inward to form an outlet, which connects to the inlet cylinder 2. The inlet chamber 1 is stably supported by a support frame, ensuring its stable suspension.

[0053] The collection unit 3, located below the liquid inlet chamber 1, includes a wastewater collection chamber 31 and a waste residue collection chamber 32 arranged in parallel. Specifically, after treatment, the wastewater and waste residue are separated and collected by the wastewater collection chamber 31 and the waste residue collection chamber 32, respectively.

[0054] A filter unit 4 is disposed between the liquid inlet cylinder 2 and the collection unit 3. 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 sludge 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 to facilitate sludge removal and solid-liquid separation.

[0055] The cleaning assembly 5 is rotatably mounted on the inlet chamber 1 and is used to extend into the filter unit 4 for cleaning or to extend out of the filter unit 4 to seal the bottom of the inlet chamber 1. Specifically, on the one hand, the cleaning assembly 5 is used to clean impurities from the filter unit 4 to reduce adhesion and prevent clogging of the filter plate 42; 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, while simultaneously sealing the bottom of the inlet chamber 1 to prevent wastewater from falling into the wastewater collection chamber 31 after the filter unit 4 leaves.

[0056] The working process in this embodiment is as follows:

[0057] During solid-liquid separation, the filter unit 4 is connected to the inlet cylinder 2 and located directly above the wastewater collection chamber 31. After being filtered by the filter unit 4, the wastewater enters the wastewater collection chamber 31. At the same time, the cleaning component 5 extends into the filter unit 4 to clean the impurities to one side, thereby preventing the filter plate 42 from becoming clogged.

[0058] During the slag emptying process, the cleaning component 5 first extends back into the inlet cylinder 2 and simultaneously seals the inlet chamber 1. At this time, the inlet chamber 1 forms a storage cavity to temporarily store the wastewater to be treated. This ensures the continuous flow of wastewater treatment without affecting its normal entry, and prevents untreated wastewater from entering the wastewater collection chamber 31, thus ensuring effective solid-liquid separation. Afterward, the filter unit 4 slides to the slag collection chamber 32, performs the slag emptying operation, and then returns to the bottom of the inlet cylinder 2.

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

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

[0061] The sealing block 52 is installed at the telescopic end of the first telescopic rod 51 and fits precisely with the bottom of the liquid inlet chamber 1 to seal it; specifically, the size of the sealing block 52 matches the bottom opening of the liquid inlet chamber 1. When the first telescopic rod 51 extends, the sealing block 52 is located below the bottom opening of the liquid inlet chamber 1, at which time wastewater flows into the filter unit 4 through the liquid inlet cylinder 2; when the first telescopic rod 51 retracts, the sealing block 52 moves upward to seal the bottom opening of the liquid inlet chamber 1.

[0062] The rotating rod 53 is rotatably mounted on the bottom of the sealing block 52; specifically, a protective groove is provided at the bottom of the sealing block 52, and a drive motor is provided in the protective groove. The drive 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 arranged circumferentially on the rotating rod 53 and used to abut against the surface of the filter plate 42. Specifically, the rotating brushes 54 abut against the surface of the filter plate 42 and move on the filter plate 42 to clean it, preventing impurities from adhering and causing blockage.

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

[0065] The first telescopic rod 51 moves the sealing block 52 and the rotating brush 54 downwards simultaneously. At this time, the sealing block 52 leaves the bottom opening of the inlet chamber 1, and the rotating brush 54 extends into the filter unit 4. Wastewater passes through the inlet chamber 1, is buffered by the sealing block 52, and flows into the inlet cylinder 2 through the gap between the sealing block 52 and the inlet chamber 1, and finally enters the filter unit 4 for filtration. At this time, the rotating rod 53 rotates under the drive of the drive motor, driving the rotating brush 54 to clean the filter plate 42 to prevent the filter plate 42 from becoming clogged.

[0066] Then, the first telescopic rod 51 drives the sealing block 52 and the rotating brush 54 to move upward simultaneously. At this time, the sealing block 52 cooperates with the bottom opening of the liquid inlet chamber 1 to seal it, while 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 sealing block 52 seals the bottom opening of the liquid inlet chamber 1. Thus, 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 chamber 1 to ensure the normal operation of wastewater treatment.

[0067] It is understood that using the rotating brush 54 to agitate the filter plate 42, compared to the existing technology that uses collision to make the filter plate 42 shake, results in a lower vibration frequency due to the spring inside the shock absorber, which may not be able to shake off the fibrous impurities adhering to the filter plate 42. The cleaning component 5 can better clean the impurities adhering to the filter unit 4, while reducing the clogging of the filter plate 42. It can automatically extend into and out of the filter unit 4 without affecting the normal movement of the filter unit 4.

[0068] Furthermore, to ensure that the wastewater to be treated can fall effectively, the sealing block 52 is configured as a conical structure. Specifically, the four sides of the sealing block 52 are inclined downwards, so that the wastewater is buffered when passing through the sealing block 52, and then slides down through the inclined surface of the sealing block 52, thereby ensuring that the wastewater can flow gently and completely into the filter unit 4.

[0069] Furthermore, such as Figure 1 and Figure 3 As shown, the filter unit 4 includes a support frame 41, a filter plate 42, and a drive component 43.

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

[0071] There are two filter plates 42, which are rotatably arranged in the middle of the support frame 41. Specifically, the filter plates 42 are used to separate fiber impurities and wastewater. The impurities after filtration are temporarily stored in the support frame 41, and the wastewater enters the wastewater collection chamber 31.

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

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

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

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

[0076] The function of the drive unit 43 is as follows: when the support frame 41 moves directly above the waste collection chamber 32, the drive unit 43 operates 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, thereby allowing the fibrous impurities on the two filter plates 42 to leak into the waste collection chamber 32. The specific working process is as follows: the working motor 432 is started, and one of them rotates...

[0077] With the shafts rotating, and under the meshing of the first gear 433 and the second gear 434, both rotating shafts 431 rotate, driving the two filter plates 42 to flip and complete the slag removal operation. Furthermore, given the high coefficient of friction between the first gear 433 and the second gear 434, and the fact that 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, during the filtration operation, the two filter plates 42 will not easily flip.

[0078] When the height of the waste collection chamber 32 is less than its width, by setting two filter plates 42, the effect is that the two filter plates 42 remain within the support frame 41 after being flipped, without affecting the normal collection of the waste collection chamber 32. At the same time, setting the rotating shaft 431 in the middle of the filter plate 42 can better provide support for the filter plate 42.

[0079] It is known that the cleaning component 5 can effectively reduce the adhesion of fibrous impurities to the filter plate 42 after cleaning. Therefore, in the subsequent slag dumping process, the impurities can be better treated by flipping the filter plate 42.

[0080] Example 2

[0081] Because there will always be a certain gap between the sealing block 52 and the bottom of the liquid inlet chamber 1, such as Figure 1 and Figure 2 As shown, to further ensure the sealing effect of the sealing block 52, it is configured that: fasteners 6 are provided on all four sides of the liquid inlet cylinder 2 to abut against the four sides of the sealing block 52.

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

[0083] The abutment block 61 is slidably disposed 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 sealing block 52 to prevent 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 sealing block 52 to move upward, the sealing block 52 abuts against the four abutting blocks 61, and the sealing block 52 and the four abutting blocks 61 are tightly connected, thereby avoiding the leakage of wastewater and causing trouble.

[0086] Example 3

[0087] To ensure the stable movement of the support frame 41, the present invention provides another embodiment, such as... Figure 4 As shown, the bottom of the support frame 41 is provided with guide wheels 7, and the top of the wastewater collection chamber 31 and the waste residue collection chamber 32 are both provided with guide rails 8 for the guide wheels 7 to slide. In this embodiment, the bottom of the support frame 41 is provided with four guide wheels 7, and guide rails 8 are provided on both sides of the wastewater collection chamber 31 and the waste residue collection chamber 32. The four guide wheels 7 slide directionally on two guide rails 8 respectively.

[0088] Example 4

[0089] In existing technologies, operators typically add chemicals to the filtered wastewater to aid in further flocculation. However, the amount of chemicals added often needs to be controlled. Adding too little chemicals may not achieve the best fusion effect, while adding too much chemicals may result in waste.

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

[0091] The feeding cylinder 91 is located at the top of the wastewater collection chamber 31 and is connected to the wastewater collection chamber 31. Specifically, the feeding cylinder 91 is engraved with graduations (not shown in the figure), and the operator can manually control the dosage. During dosing, the amount of dosing is indicated by the change in the dosage on the feeding cylinder 91.

[0092] The operating lever 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 stop block 94 is located at one end of the operating rod 92 and is used to open or close the connection between the wastewater collection chamber 31 and the feeding cylinder 91.

[0095] The specific working method is as follows: by pressing the operating lever 92, the operating lever 92 drives the stop block 94 to move downward together, so that the stop block 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 no external force is applied to the operating lever 92, under the action of the elastic force of the second spring 93, the second spring 93 drives the operating lever 92 to return to its original position. At this time, the stop block 94 moves upward to seal the connection between the wastewater collection chamber 31 and the feeding cylinder 91.

[0097] It should be noted that the weight of the drug in the feeding cylinder 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 cylinder 91. Only after an external force is applied will the block 94 move away, and the drug can enter the wastewater collection chamber 31.

[0098] To ensure thorough integration of the drug with the treated wastewater, a stirring mechanism is installed within the wastewater collection chamber 31. Specifically, the stirring mechanism includes stirring blades, a stirring shaft, and a first motor. The stirring shaft is connected to the first motor, and the stirring blades are circumferentially arranged on the stirring shaft. Driven by the first motor, the stirring shaft rotates the stirring blades within the wastewater collection chamber 31, thereby ensuring that the drug is more evenly integrated into the water.

[0099] In addition, a waste bin 10 is slidably arranged inside the waste collection chamber. The replaceable waste bin 10 ensures continuous waste recycling, and the waste bin 10 can be replaced during the filtration and separation process, thereby ensuring continuous wastewater treatment.

[0100] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment 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 within the scope of protection of the present invention.
