Description

Technical Field

[0001] The utility model relates to wastewater treatment equipment, in particular to wastewater treatment equipment used in dyeing process. Background Art

[0002] There are a lot of impurities in dyeing wastewater, and these impurities include a lot of hairy impurities. It should be noted that hairy impurities are organic impurities. When entering the subsequent sewage treatment steps, they will be decomposed by bacteria, which will increase the sewage treatment load and affect the treatment effect of biological treatment, chemical treatment and other processes. At the same time, hairy impurities will also be adsorbed on the pipe wall of the sewage pipe in large quantities, and then agglomerate on the pipe wall, and finally block the pipe, filter and other equipment, resulting in reduced sewage treatment efficiency or even failure to proceed normally. Utility Model Content

[0003] The utility model aims to provide a wastewater treatment device for dyeing process, so as to filter the dyeing wastewater in time and reduce the extra burden caused by hairiness in the dyeing wastewater treatment process.

[0027] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1 , Figure 2 The wastewater treatment equipment for dyeing process shown in the figure comprises a cement cast support surface 100, on which a water tank 110 is provided to guide the dyeing wastewater. A filtering mechanism is provided on the water tank to filter the hairiness in the dyeing wastewater. Specifically, as Figure 1As shown, the filtering mechanism includes a filter screen 200, which is a metal mesh and is installed in an arc shape above the water tank. At the same time, a drain pipe 400 is installed above the water tank, and the water outlet end of the drain pipe is guided to the top of the filter screen so that the discharged dyeing wastewater can be directly poured onto the filter screen. In addition, a motor 1000 is installed above the water tank, and the output shaft of the motor is coaxially arranged with the filter screen. Figure 1 As shown, a connecting rod 900 extending radially along the output shaft is connected to the output shaft of the motor, and the connecting rod extends to the filter screen. A brush 300 is connected to the end of the connecting rod away from the motor. Figure 1 As shown, the brush extends along the axial direction of the filter so that the bristles of the brush contact the upper surface of the filter. When the brush follows the action of the motor, it can brush the hair filtered by the filter, thereby sweeping the hair on the filter out of the filter, cleaning the filter and ensuring that the filter can continue to filter stably.

[0031] In addition, it should be noted that, based on the above scheme, one filter screen can be increased to two. The two filter screens are distributed in the upper and lower structures and are coaxially arranged. So that after the upper filter screen has filtered, the lower filter screen can also filter the dyed wastewater once. The advantage of this form is that the hairiness in the dyed wastewater can be filtered out as much as possible. It should be noted that in order to improve the filtering efficiency, the mesh size of the upper filter screen can be made larger than the mesh size of the lower filter screen. And adapted to this, in this scheme, there are two brushes. The two brushes are respectively connected to the connecting rod, and it needs to be ensured that while following the movement of the connecting rod, the brush can brush and sweep onto the upper surface of the corresponding filter screen.

[0032] In addition, after a long period of brushing, the bristles of the brush will inevitably become tangled with the filtered feathers, which greatly affects the brushing efficiency of the brush. For this reason, the brush needs to be cleaned regularly. However, it is obviously very inconvenient to shut down the machine. For this reason, it is necessary to design a mechanism that can automatically clean the brush. Specifically, Figure 1 As shown, a steel brush 500 is also provided above the gutter. Specifically, the two steel brushes are arranged on the circular trajectory of the brush movement, so that when the brush moves to the location of the steel brush, the steel needle on the steel brush can be inserted into the bristles of the brush, thereby screening out the hair entangled with the brush.

[0033] However, after the steel brush has been used to clean the hair brush for a period of time, a large amount of hair will inevitably accumulate on the steel brush, thereby affecting the cleaning effect of the steel brush. For this reason, in this solution, a vibrator 600 is considered to be provided, which is connected to the steel brush so that the steel brush can vibrate at a high frequency under the drive of the vibrator. With the high-frequency vibration of the steel brush, the hair on the steel brush can be shaken off by the shaking steel brush, thereby avoiding a large amount of hair accumulation on the steel brush.

[0034] It should also be noted that if the hairs cleaned by the steel brush and the hairs swept from the filter by the brush and directly fall outside the filter cannot be centrally processed, it will inevitably cause sewage to flow across the workshop. For this reason, a storage tank 120 is also provided under the steel brush, and the storage tank is also located on the side of the filter, so that the hairs swept by the brush and falling from the steel brush can fall into the storage tank, so that the filtered hairs can be centrally collected.

[0035] However, it should be noted that if the storage tank does not have a drainage function, the large amount of sewage adsorbed in the feathers will easily cause the feathers to be in a very humid environment. At this time, the feathers, as organic matter, are easily decomposed by microorganisms and produce unpleasant odors. For this reason, a flow channel 130 is also opened below the location of the storage tank, and the drainage end of the flow channel leads to the sink. Filter holes 140 are evenly opened on the bottom of the storage tank to connect the storage tank with the flow channel. At this time, the large amount of dyeing wastewater adsorbed by the feathers placed in the storage tank penetrates into the flow channel through the filter holes due to the effect of gravity, which effectively reduces the water content of the feathers, destroys the decomposition environment of the feathers, and effectively reduces the generation of odors. In addition, the seeping sewage is finally discharged back into the sink and eventually merges with the dyeing sewage.

[0036] Finally, it should be noted that in this solution, a pressing plate 800 can be set in the storage tank 120, and a telescopic cylinder 700 is installed on the support surface, and the telescopic cylinder is located at one end of the storage tank and connected to the pressing plate. The telescopic cylinder is extended at a fixed time to push and squeeze the hair collected in the storage tank into a piece, thereby accelerating the squeezing of sewage in the hair, reducing the humidity of the hair, and preventing the hair from generating odor due to the decomposition of microorganisms in a humid environment.

[0037] Working principle: The drainage pipe receives the dyeing wastewater discharged after dyeing. The dyeing wastewater is poured onto the filter under the guidance of the drainage pipe. The two layers of filter screens filter the dyeing wastewater twice to filter out the hairiness in the dyeing wastewater as much as possible. While filtering the hairiness, the motor also rotates synchronously. As the motor rotates, it drives the brush on the connecting rod to brush through the surface of the filter screen. The hairiness filtered by the filter screen is also swept out of the filter screen by the brush to clean the filter screen. It should be noted that in the process of long-term brushing of the filter screen, it is inevitable that some hairiness will be entangled, which will affect the brushing effect of the brush. At this time, the steel brush set on the side can comb the bristles of the rotating brush to filter out the tangled hairiness on the brush. In addition, the vibrator connected to the steel brush can shake the combed hairiness into the storage tank below to keep the steel brush clean. It should be noted that the existence of the storage tank can collect the cleaned hairiness to prevent the sewage adsorbed in the hairiness from flowing everywhere in the workshop.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
