Technical Field

[0001] This application relates to the technical field of wastewater treatment and recycling, and in particular to a device for recycling wastewater from a dyeing machine. Background Technology

[0002] In the textile printing and dyeing industry, the dyeing process is an extremely important step. With the continuous development of the industry, dyeing techniques have become increasingly diverse and sophisticated, enabling the production of textiles with rich colors and superior quality. This meets market demands for fabrics of different colors and styles, greatly promoting the prosperity of the textile industry and playing a crucial role in many fields such as clothing and home textiles. However, the dyeing process generates a large amount of wastewater. Direct discharge of this wastewater not only results in a serious waste of water resources but also causes significant environmental pollution. Therefore, how to effectively treat and recycle dyeing machine wastewater has become a critical issue that urgently needs to be addressed within the industry.

[0003] Currently, the treatment and recycling of dyeing machine wastewater mostly involves filtering the wastewater through multiple layers of filters to remove larger particles. However, this method has almost no filtering effect on micron-sized or even smaller pollutants and cannot fully purify the wastewater. Utility Model Content

[0004] In order to improve the effect of wastewater treatment, this application provides a dyeing machine wastewater recycling device.

[0005] This application provides a wastewater recycling device for a dyeing machine, which adopts the following technical solution: it includes a wastewater collection tank for collecting wastewater discharged from the dyeing machine, and also includes a flocculant dosing structure and a multi-stage filtration structure. A pretreatment tank is connected to the front of the wastewater collection tank, the flocculant dosing structure is installed in the pretreatment tank, the multi-stage filtration structure is installed in the wastewater collection tank, and the outlet of the wastewater collection tank is connected to the dyeing machine.

[0006] By adopting the above technical solution, and by setting up a flocculant dosing structure in the pretreatment tank, the flocculant is fully mixed with the wastewater, causing the fine impurities in the wastewater to agglomerate into larger particles, which facilitates subsequent filtration. The multi-stage filtration structure can remove impurities in the wastewater in stages and at multiple levels, realizing the effective treatment and recycling of dyeing machine wastewater. This reduces water waste, lowers environmental pollution, improves wastewater treatment efficiency, and has higher effectiveness.

[0007] Preferably, the flocculant dosing structure includes a storage tank and a mixing component. The storage tank is used to store flocculant and is located on one side of the pretreatment tank. The storage tank and the pretreatment tank are connected by a first pipe. The mixing component is located inside the pretreatment tank and is used to mix the flocculant with the wastewater.

[0008] By adopting the above technical solution, the flocculant stored in the storage tank is added to the pretreatment tank through the first pipeline. Through flocculation, the suspended solids, colloids and other impurities in the wastewater are agglomerated into larger particles, which facilitates subsequent filtration or sedimentation.

[0009] Preferably, the mixing assembly includes a mixing motor, a drive rod, and multiple mixing rods. The mixing motor is disposed at the bottom of the pretreatment box, the drive rod is disposed inside the pretreatment box and one end of the drive rod is coaxially connected to the output shaft of the mixing motor, the mixing rods are arranged radially along the drive rod, and the multiple mixing rods are arranged at equal angular intervals circumferentially along the drive rod.

[0010] By adopting the above technical solution, when the mixing motor starts, it can drive the drive rod to rotate, which in turn drives the mixing rod to rotate. Under the stirring action of the mixing rod, the flocculant entering the pretreatment tank can be mixed more evenly with the wastewater.

[0011] Preferably, the drive rod has a main flocculant flow chamber, and the multiple mixing rods have secondary flocculant flow chambers. The first pipe is connected to the main flocculant flow chamber, and the main flocculant flow chamber and the secondary flocculant flow chambers are connected. The mixing rod has multiple flow holes, which are evenly distributed on the surface of the mixing rod and are connected to the secondary flocculant flow chambers.

[0012] By adopting the above technical solution, when the flocculant in the storage tank enters the main flocculant flow chamber through the first pipe, it will be diverted to each secondary flocculant flow chamber, and then flow into the wastewater in the pretreatment tank through the flow hole. Under the stirring action of the mixing rod, it can be mixed more evenly with the wastewater.

[0013] Preferably, a heating chamber is formed on the wall of the storage tank along the circumference of the storage tank, and a heating tube is provided inside the storage tank, the heating tube being spirally embedded in the heating chamber.

[0014] By adopting the above technical solutions, heating the flocculant can improve its activity and solubility, enabling it to better exert its flocculation effect.

[0015] Preferably, the multi-stage filtration structure includes a coarse filter screen and multiple layers of fine filter cartridges. The coarse filter screen and the multiple layers of fine filter cartridges are arranged sequentially from top to bottom in the wastewater collection tank along the depth direction of the wastewater collection tank. After the wastewater in the pretreatment tank enters the wastewater collection tank, it passes through the coarse filter screen and the multiple layers of fine filter cartridges in sequence.

[0016] By adopting the above technical solution, the wastewater in the pretreatment tank enters the wastewater collection tank and then passes through a coarse filter screen and multiple layers of fine filter cartridges in sequence. The coarse filter screen can filter out larger particulate impurities in the wastewater, while the multiple layers of fine filter cartridges further remove fine impurities in the wastewater.

[0017] Preferably, the wastewater collection tank is also equipped with a backwashing assembly, which includes a high-pressure water pump and a backwashing water gun. The water outlet direction of the backwashing water gun is opposite to the direction of the filtered water flow.

[0018] By adopting the above technical solution, the high-pressure water pump can provide sufficient pressure, so that the water sprayed by the backwash water gun has a strong impact force, which can effectively clean the impurities attached to the filter structure.

[0019] Preferably, an adjusting ball is fitted at the end of the backwash water gun away from the outlet, the adjusting ball is embedded in the bottom of the wastewater collection tank, and the adjusting ball is rotatably connected to the bottom wall of the wastewater collection tank.

[0020] By adopting the above technical solution, the spray angle of the backwash water gun can be adjusted by rotating the adjusting ball, so as to backwash the filter structure more comprehensively.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a wastewater recycling device for dyeing machines, which is used to improve the wastewater treatment effect.

[0033] refer to Figure 1 , Figure 2 and Figure 3A wastewater recycling device for a dyeing machine includes a wastewater collection tank 150, a flocculant dosing structure 120, a multi-stage filtration structure 130, an adsorption tank 110, and a water storage tank 111. The wastewater collection tank 150 is used to collect wastewater discharged from the dyeing machine 1. A pretreatment tank 140 is connected to the wastewater collection tank 150. The flocculant dosing structure 120 is installed in the pretreatment tank 140, and the multi-stage filtration structure 130 is installed in the wastewater collection tank 150. The outlet of the wastewater collection tank 150 is connected to the dyeing machine 1. By setting the flocculant dosing structure 120 in the pretreatment tank 140, the flocculant is fully mixed with the wastewater, causing the fine impurities in the wastewater to agglomerate into larger particles, which facilitates subsequent filtration. The multi-stage filtration structure 130 can remove impurities in the wastewater in stages and at multiple levels, realizing the effective treatment and recycling of wastewater from the dyeing machine 1. This reduces water waste, lowers environmental pollution, improves wastewater treatment efficiency, and has higher efficiency.

[0034] In this embodiment, the dyeing machine 1 and the pretreatment tank 140 are connected by a first return pipe 112, the pretreatment tank 140 and the wastewater collection tank 150 are connected by a second return pipe 113, the outlet of the wastewater collection tank 150 is connected to a third return pipe 114, the other end of the third return pipe 114 is connected to the adsorption tank 110, the adsorption tank 110 and the water storage tank 111 are connected by a fourth return pipe 115, and the water storage tank 111 and the dyeing machine 1 are connected by a fifth return pipe 116. The second return pipe 113 is connected to a first water pump 117, the fourth return pipe 115 is connected to a second water pump 118, and the fifth return pipe 116 is connected to a third water pump 119.

[0035] For details, please refer to Figure 2 The flocculant dosing structure 120 includes a storage tank 121 and a mixing component 122. The storage tank 121 is used to store flocculant and is located on one side of the pretreatment tank 140. A heating chamber 123 is provided on the tank wall of the storage tank 121 around the circumference of the storage tank 121. A heating pipe 124 is provided inside the storage tank 121 and is spirally embedded in the heating chamber 123. The heating pipe 124 can be an electric heating pipe 124, which converts electrical energy into heat energy to heat the flocculant in the storage tank 121, or a steam heating pipe 124, which uses the heat of steam for heating. Heating the flocculant can improve its activity and solubility, allowing it to better exert its flocculation effect.

[0036] The storage tank and the pretreatment tank 140 are connected by a first pipe 125. A mixing assembly 122 is disposed within the pretreatment tank 140 and is used to mix the flocculant with the wastewater. The mixing assembly 122 includes a mixing motor 1221, a drive rod 1222, and multiple mixing rods 1223. The mixing motor 1221 is disposed at the bottom of the pretreatment tank 140 and is typically a waterproof motor to prevent damage from wastewater immersion. The drive rod 1222 is disposed within the pretreatment tank 140 and one end is coaxially connected to the output shaft of the mixing motor 1221. In this embodiment... In the pretreatment tank 140, the drive rod 1222 is inserted at the bottom center position. The mixing rod 1223 is arranged radially along the drive rod 1222. Multiple mixing rods 1223 are arranged at equal angles around the drive rod 1222. The mixing rod 1223 is cylindrical with a smooth surface to facilitate the flow of wastewater. When the mixing motor 1221 is started, it can drive the drive rod 1222 to rotate, which in turn drives the mixing rod 1223 to rotate. Under the stirring action of the mixing rod 1223, the flocculant entering the pretreatment tank 140 can be mixed more evenly with the wastewater.

[0037] Further, refer to Figure 2 and Figure 4 The drive rod 1222 has a main flocculant flow chamber 126, and multiple mixing rods 1223 have secondary flocculant flow chambers 127.

The flow holes 128 are connected to the secondary flocculant flow chambers 127. When the flocculant in the storage tank 121 enters the main flocculant flow chamber 126 through the first pipe 125, it will be diverted to each secondary flocculant flow chamber 127, and then flow into the wastewater in the pretreatment tank 140 through the flow holes 128. Under the stirring action of the mixing rod 1223, it can be mixed more evenly with the wastewater. Through flocculation, the suspended solids, colloids and other impurities in the wastewater are agglomerated into larger particles, which are convenient for subsequent filtration or sedimentation.

[0038] Further, refer to Figure 3 and Figure 5The multi-stage filtration structure 130 includes a coarse filter screen 131 and a multi-layer fine filter element 132. The coarse filter screen 131 and the multi-layer fine filter element 132 are arranged sequentially from top to bottom within the wastewater collection tank 150 along its depth direction. Wastewater from the pretreatment tank 140 enters the wastewater collection tank 150 and passes through the coarse filter screen 131 and the multi-layer fine filter element 132 sequentially. In this embodiment, the coarse filter screen 131 is a metal mesh, which can filter out larger particles of impurities in the wastewater. The multi-layer fine filter element 132 is a ceramic filter element, which further removes fine impurities in the wastewater. The adsorption tank 110 is filled with honeycomb activated carbon adsorption blocks 1101, with the honeycomb pores opening horizontally for flow.

[0039] In addition, refer to Figure 3 and Figure 6 The wastewater collection tank 150 is also equipped with a backwashing assembly 160, which includes a high-pressure water pump 161 and a backwashing water gun 162. The water outlet direction of the backwashing water gun 162 is opposite to the direction of the filtered water flow. The high-pressure water pump 161 can provide sufficient pressure so that the water sprayed by the backwashing water gun 162 has a strong impact force, which can effectively clean the impurities attached to the multi-stage filter structure 130. An adjusting ball 163 is fitted on the end of the backwashing water gun 162 away from the outlet. The adjusting ball 163 is embedded in the bottom of the wastewater collection tank 150 and is damped and rotatably connected to the bottom wall of the wastewater collection tank 150. By rotating the adjusting ball 163, the spray angle of the backwash water gun 162 can be adjusted to more comprehensively backwash the filter structure. In this embodiment, the high-pressure water pump 161 is connected to the water supply tank 164. An adjusting handle 166 and a connecting handle 167 are provided between the high-pressure water pump 161 and the adjusting ball 163. The backwash water gun 162 and the high-pressure water pump 161 are connected by a connecting hose 165. The adjusting handle 166, the connecting handle 167 and the adjusting ball 163 are sequentially fitted onto the connecting hose 165.

[0040] The implementation principle of the dyeing machine wastewater recycling device in this application embodiment is as follows: By setting a flocculant addition structure 120 in the pretreatment tank 140, the flocculant is fully mixed with the wastewater, causing the fine impurities in the wastewater to agglomerate into larger particles, which facilitates subsequent filtration. The multi-stage filtration structure 130 can remove impurities in the wastewater in stages and at multiple levels, improving the filtration effect. The backwashing component 160 can periodically clean the filtration structure, keeping it unobstructed and efficient, and extending its service life. The entire device realizes the effective treatment and recycling of dyeing machine 1 wastewater, which reduces water waste and environmental pollution. Compared with existing wastewater treatment methods, it has better treatment effect and higher efficiency.
