Description

Technical Field

[0001] This utility model relates to wastewater treatment system technology, specifically a total antimony adsorption device for dyeing and printing wastewater. Background Technology

[0002] Antimony, a heavy metal, is generated during the dyeing and printing process of textiles. Due to its toxic nature, it needs to be properly purified before it can be discharged. This includes methods such as chemical precipitation, electrochemical methods, and ion exchange to effectively remove total antimony.

[0003] For example, the publication (announcement) number: CN207748994U, publication (announcement) date: 2018-08-21, discloses a wastewater treatment system for antimony-containing dyeing and printing, including an equalization tank, a cooling tower, a primary sedimentation tank, an aerobic tank, a secondary sedimentation tank, a submerged ultrafiltration (MCR) tank, a reverse osmosis (RO) membrane system, a final sedimentation tank, and an external discharge tank connected in sequence by pipelines. The system uses PAC (polyacrylamide) to produce a flocculation reaction in the primary sedimentation tank and microbial adsorption in the aerobic tank. After sedimentation, the wastewater is discharged through a sludge treatment system, thereby reducing the total antimony in the wastewater.

[0004] The shortcoming of the existing technology is that, in order to improve the adsorption efficiency of total antimony, the source wastewater discharged into the treatment pond needs to be filtered in advance to reduce the interference of debris and waste textiles on the treatment process. However, since the wastewater usually contains particulate matter and oil, the filtration process requires certain equipment and high costs. Usually, this part of the pollution is ignored and left to settle naturally in the treatment pond, and is cleaned manually on a regular basis. Therefore, it will inevitably have a certain impact on the purification work. Utility Model Content

[0005] The purpose of this invention is to provide a total antimony adsorption device for dyeing and printing wastewater to overcome the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A total antimony adsorption device for dyeing and printing wastewater includes a wastewater pipe with a drain pipe, wherein a filter component consisting of a lower filter plate and an upper filter plate is vertically movable in the drain pipe.

[0008] The filter element moves upward to the stop position, causing the upper filter plate to be driven to close with the lower filter plate.

[0009] As a further description of the above technical solution: multiple elastic elements are fixedly installed on the upper filter plate.

[0010] As a further description of the above technical solution: a stop block that abuts against the upper filter plate is fixedly installed at the upper port of the pipe.

[0011] As a further description of the above technical solution: the lower filter plate is provided with a screw that is threadedly engaged with it.

[0012] As a further description of the above technical solution: the inner wall of the pipe is provided with multiple vertical grooves, and a slider that slides in the grooves is fixedly installed on the side wall of the lower filter plate.

[0013] As a further description of the above technical solution, it also includes a cleaning platform that is fixedly installed on the port of the pipe.

[0014] As a further description of the above technical solution: a fixed frame is fixedly installed on the cleaning platform, and the screw is rotatably mounted on the fixed frame.

[0015] As a further description of the above technical solution, it also includes a water supply pipe installed on the sewage pipe for supplying water to the drain pipe.

[0016] As a further description of the above technical solution: the water supply pipe is connected to the filter component after the water reaches the termination position.

[0017] As a further description of the above technical solution: the elastic element is specifically a spring.

[0018] In the above technical solution, the total antimony adsorption device for dyeing and printing wastewater provided by this utility model has the following beneficial effects: by filtering the wastewater before it enters the treatment tank, the wastewater is retained by the filter components, which improves the adsorption efficiency of total antimony in the treatment tank. When the filter components are moved upward to the liquid surface at the upper opening, the retained wastewater picks up the floating oil, thereby separating the wastewater and oil from the wastewater together. During the process of multiple upper filter plates closing together and the lower filter plates approaching each other, the residual wastewater in the wastewater is squeezed out. Finally, the wastewater on the filter components is cleaned manually to ensure the cleanliness of the filter components, thereby improving and ensuring the filtration efficiency of the wastewater and having less impact on the wastewater purification work.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a total antimony adsorption device for dyeing and printing wastewater, including a wastewater pipe 1 with a drain pipe 2, and a filter component consisting of a lower filter plate 4 and an upper filter plate 5 that moves vertically in the drain pipe 2;

[0028] The filter element moves upward to the end position, causing the upper filter plate 5 to be driven to close with the lower filter plate 4.

[0029] Specifically, sewage pipe 1 is used to discharge sewage to be treated, and drain pipe 2 (with an inner diameter of 1.5 meters) has openings at the top and bottom. The bottom opening is used to discharge sewage into the treatment tank, while the top opening maintains a predetermined distance from the liquid surface under atmospheric pressure, and gives the sewage the ability to float oil to the surface.

[0030] Furthermore, there are multiple upper filter plates 5, with the holes gradually decreasing in size from top to bottom, and the gap between each pair of upper filter plates 5 is used to retain dirt of different sizes; the lower filter plate 4 has the smallest holes, and the filter element is located at the lower opening.

[0031] Wastewater is fed into drain pipe 2 through wastewater pipe 1 and treated by the filter components before entering the treatment tank. This process retains impurities in the wastewater, improving the adsorption efficiency of total antimony in the treatment tank. When a large amount of impurities accumulates on the filter components and cleaning is required, the filter components are moved upwards to the liquid surface at the upper opening. This allows the retained impurities to scoop up floating oil (essentially acting as a ladle, using the impurities to adhere to and extract the oil), thus separating the impurities and oil from the wastewater (the filter components detach from the wastewater in drain pipe 2). As the multiple upper filter plates 5 close together and the lower filter plates 4 approach, residual wastewater is squeezed out from the impurities. Finally, the impurities on the filter components are manually cleaned to ensure cleanliness, thereby improving and ensuring filtration efficiency and minimizing impact on wastewater purification. Furthermore, the equipment is simpler and more efficient to use, with lower treatment costs.

[0032] In another embodiment of this utility model, a plurality of elastic elements 51 are fixedly installed on the upper filter plate 5.

[0033] Specifically, the elastic element 51 is installed by tightening bolts and nuts at both ends. Before cleaning the retained dirt, the multiple upper filter plates 5 are disassembled to ensure better stability of the upper filter plates 5 under the bolt and nut installation. The cleaning cycle is two months.

[0034] During the process of the upper filter plate 5 being brought together, multiple elastic elements 51 are compressed and deformed so that when the filter component returns to its downward position, the elastic elements 51 will automatically recover their deformation.

[0035] In another embodiment of this utility model, a stop block 23 that abuts against the upper filter plate 5 is fixedly installed at the upper port of the pipe 2.

[0036] Specifically, the baffle 23 is integrally formed on the inner wall of the pipe 2.

[0037] After the uppermost filter plate 5 moves upward and touches the stop block 23, the lower filter plate 4 continues to move upward and actively compresses the elastic element 51 to deform, causing the gap between each plate to decrease and the residual sewage to be squeezed out.

[0038] In another embodiment of this utility model, a screw 3 is provided on the lower filter plate 4 for threaded engagement.

[0039] The filter element is moved up and down by manually rotating screw 3.

[0040] In another embodiment of the present invention, the inner wall of the pipe 2 is provided with a plurality of vertical grooves 42, and a slider 41 that slides in the grooves 42 is fixedly installed on the side wall of the lower filter plate 4.

[0041] Specifically, the chute 42 can be periodically rinsed with a high-pressure water gun; the slider 41 is integrally formed on the side of the lower filter plate 4.

[0042] The slider 41 provides guidance and support for vertical sliding, making the lower filter plate 4, which has the ability to carry upwards, more stable when moving, and also ensuring the stability of the upper filter plate 5 under drive.

[0043] In another embodiment of the present invention, a cleaning platform 21 is also included, which is fixedly installed on the port of the pipe 2.

[0044] Specifically, the cleaning platform 21 is a funnel-shaped shell.

[0045] By temporarily storing the removed waste on the inner wall of the cleaning platform 21, workers have more operating space when transferring the waste, and the inclined inner wall of the cleaning platform 21 can also be used to dry and dehydrate the waste.

[0046] In another embodiment of this utility model, a fixing frame 22 is fixedly installed on the cleaning platform 21, and the screw 3 is rotatably mounted on the fixing frame 22.

[0047] Specifically, the screw 3 and the fixing frame 22 are equipped with damping or self-locking components (equivalent to the river gate drive components in the prior art) at their rotation positions, and the fixing frame 22 is detachably connected to the upper port of the cleaning platform 21 by bolts and nuts at both ends.

[0048] The fixed frame 22 provides support for the stable rotation of the screw 3, and also makes it convenient for staff to step on the fixed frame 22 to perform manual rotation operations.

[0049] In another embodiment of the present invention, a water supply pipe 6 is provided on the sewage pipe 1 and used to supply water to the drain pipe 2.

[0050] Specifically, the water supply pipe 6 transports the treated water from the treatment tank, and a valve can be detachably installed at the flange of the lower end of the water supply pipe 6 (the valve and its installation method are existing technologies and will not be described in detail here).

[0051] By using a water pump to flush the inner wall of drain pipe 2 with treated water (provided that the valve of sewage pipe 1 is closed), the possibility of dirt adhering to the inner wall of drain pipe 2 is reduced.

[0052] In another embodiment of this utility model, the water supply pipe 6 supplies water in conjunction with the filter component after it reaches the termination position.

[0053] By increasing the water pressure at the outlet of the water supply pipe 6, the liquid level entering the drain pipe 2 is made higher than the original liquid level of the sewage being transported. At this time, multiple upper filter plates 5 are reinstalled, and the treated water is used to soak and rinse the filter components, making the filter components cleaner and tidier before operation.

[0054] In another embodiment of this utility model, the elastic element 51 is specifically a spring.

[0055] The use of springs can reduce the cost of elastic element 51 (common in the market), and the high strength and long service life of springs enable elastic element 51 to have excellent performance.

[0056] Working principle: Wastewater is sent to drain pipe 2 through sewage pipe 1 and treated by the filter components before entering the treatment tank to retain the dirt in the wastewater and improve the adsorption efficiency of total antimony in the treatment tank. When a lot of dirt is retained on the filter components and cleaning is required, the filter components are moved upward to the liquid surface at the upper opening, so that the retained dirt picks up the floating oil, thereby separating the dirt and oil from the wastewater. As the multiple upper filter plates 5 close together and the lower filter plates 4 approach each other, the residual wastewater in the dirt is squeezed out. Finally, the dirt on the filter components is cleaned manually to ensure the cleanliness of the filter components.

[0057] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
