Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laundry liquid production equipment, in particular to a laundry liquid waste liquid recycling device. BACKGROUND

[0002] With the emphasis on environmental protection concepts and the development of technology around the world, washing products tend to diversify, but energy-saving, water-saving, high-efficiency, mild, convenient to use and meet the requirements of safe and environmentally friendly products become the mainstream development direction. With the rapid development of the washing industry, the amount of laundry liquid waste liquid is increasing, and the waste liquid contains a large amount of unreacted detergents, volatile gases and impurities. Direct discharge not only causes waste of resources, but also pollutes the environment. At present, there are some technologies for recycling laundry liquid waste liquid, but there are problems such as low processing efficiency, poor separation effect, and unsatisfactory recycling effect.

[0003] Therefore, the related technology provides a waste liquid recycling device, which comprises a purification tank provided with an opening at the top, a filter assembly and a purification assembly, a cover door is rotatably installed at the top of the purification tank through a hinge, a feed pipe is installed on one side of the top of the purification tank, the filter assembly is installed at the top of the purification tank, and the purification assembly is installed at the bottom of the purification tank. By using the filter screen, large particle impurities in the wastewater can be filtered and absorbed, ensuring the cleanliness of the water source and realizing the absorption of impurities in the wastewater. Although the related technology can remove impurities from the waste liquid, volatile gases will be released in large quantities during the removal of impurities. These volatile gases contain perfume, surfactant, solvent and other additives. If these gas components are not recycled and directly released into the air during the waste liquid treatment process, it will cause serious air pollution. In addition, these gas components contain a large amount of perfume and surfactant components that are beneficial to production and utilization, and if they are not reasonably recycled, it will cause waste of resources. SUMMARY

[0004] The present application aims to provide a laundry liquid waste liquid recycling device to solve the technical problem of unreasonable recycling of volatile gases in laundry liquid waste liquid.

[0005] The present application provides a laundry liquid waste liquid recycling device, which comprises:

[0006] A waste liquid stirring tank is provided with a first cavity for containing waste liquid and an outlet for discharging liquid;

[0007] A volatile gas extraction tank is provided with a second cavity and an inlet for liquid, and a connecting pipe is arranged between the inlet and the outlet;

[0008] A volatilization promoting component is arranged inside the gas extraction tank, and is arranged close to the inlet through which the waste liquid flows, and is capable of promoting the volatilization of the volatile gas in the waste liquid;

[0009] A filter is arranged on the volatilization promoting component;

[0010] A collection tank is in communication with the volatile gas extraction tank, and is used to collect the volatile gas extracted from the waste liquid;

[0011] The filter filters the waste liquid when the waste liquid flows through the volatilization promoting component.

[0012] By using the above technical solution, the waste liquid stirring tank serves as a storage for the waste liquid, and ensures that the waste liquid can be effectively collected and treated. After the waste liquid is introduced into the second cavity through the inlet, the volatile gas is promoted to volatilize by the volatilization promoting component, and the release rate is increased. By using the above solution, the release of the volatile gas is promoted and recycled. In addition, the waste liquid is effectively filtered by using the filter during the process of promoting the release of the volatile gas, and thus the effect of reasonably recycling the laundry liquid waste liquid and the volatile gas therein is achieved.

[0013] Optionally, the volatilization promoting component comprises:

[0014] A volatilization plate is arranged, and a plurality of particle filtering grooves are formed in the volatilization plate, the filter is arranged in the particle filtering groove, the volatilization plate is arranged obliquely relative to the bottom wall of the volatile gas extraction tank, and the high end of the volatilization plate is fixedly connected to the inner wall of the volatile gas extraction tank.

[0015] By using the above technical solution, the volatilization plate is arranged obliquely, which is helpful for the natural flow of the waste liquid and guides the waste liquid to the inlet of the volatile gas extraction tank. By introducing the waste liquid to the volatilization plate, the contact area between the waste liquid and the air is larger, and the release of the volatile gas therein is promoted. In addition, the volatilization plate can filter the waste liquid at the same time by using the filter in the filtering groove, and thus the solid particles or other impurities heavier than the waste liquid in the waste liquid can be effectively filtered out by gravity while the volatile gas is collected.

[0016] Optionally, the volatilization plate is a plurality of volatilization plates, and the plurality of volatilization plates are arranged in a reciprocating polyline shape in the volatile gas extraction tank, and the lowest point of one volatilization plate is close to and above the highest point of the adjacent volatilization plate.

[0017] By adopting the above technical scheme, the plurality of volatile plates are arranged in a reciprocating fold line shape in the volatile gas extraction box, so that the waste liquid reciprocally flows between the volatile plates, effectively increasing the contact area between the waste liquid and the volatile plates. The waste liquid alternately flows between the volatile plates, so that the waste liquid can more fully contact the volatile plates, thereby improving the release efficiency of the volatile gas. In addition, the filter groove and the filter element arranged on each volatile plate can effectively filter solid particles or other impurities in the waste liquid. Since the waste liquid reciprocally flows between the volatile plates, the waste liquid contacts the filter element more when passing through the filter groove, thereby increasing the filtering effect.

[0018] Optionally, the volatile plate comprises a plurality of volatile segments and a plurality of filter segments, the volatile segments are arranged at intervals with the filter segments, the particle filter groove is located on the filter segment, the filter segment is parallel to the bottom wall of the volatile gas extraction box, and the volatile segment is arranged obliquely relative to the bottom wall.

[0019] By adopting the above technical scheme, the volatile segment is arranged obliquely relative to the bottom wall, so that the flow rate of the waste liquid is increased when passing through the volatile segment, and the waste liquid is filtered and slowed down through the particle filter groove, thereby improving the impact of the waste liquid on the filter plate and improving the filtering effect.

[0020] Optionally, the filter element is a plurality of filter screens, and the mesh number of the plurality of filter screens gradually increases from the highest point to the lowest point of the volatile plate.

[0021] By adopting the above technical scheme, the filtering effect is more comprehensive and complete, and the filter screen with gradually increasing mesh number can more effectively perform step-by-step layered filtering, thereby improving the filtering effect.

[0022] Optionally, the volatile promoting assembly further comprises:

[0023] The air blower has a blowing port, the air blower is arranged on the inner wall of the volatile gas extraction box and the blowing port faces the volatile plate, and the air blower is a plurality of air blowers, and the plurality of air blowers are close to the lowest point of the volatile plate.

[0024] By adopting the above technical scheme, the airflow is blown out from the air blower and faces the volatile plate, so that the flow direction of the waste liquid is opposite to the airflow, thereby forming a stronger convection, further increasing the contact area between the waste liquid and the air, accelerating the release of the volatile gas in the waste liquid, and improving the waste liquid treatment efficiency.

[0025] In addition, since the air blower is close to the lowest point of the volatile plate, the airflow can more directly cover the entire volatile plate, thereby promoting the release of the volatile gas in the waste liquid.

[0026] Optionally, a circulating tank is arranged at the bottom of the volatile gas extraction tank, a circulating pipe is arranged on the circulating tank, the circulating pipe and the connecting pipe are in communication, a circulating pump is arranged on the circulating pipe, and the circulating pump is used to drive the waste liquid in the circulating tank to circulate into the second cavity for volatilization.

[0027] By adopting the above technical scheme, the circulating pump extracts the waste liquid from the circulating tank through the circulating pipe and circulates into the second cavity through the connecting pipe. By adopting the above scheme, the waste liquid can be continuously sent into the volatilization area, and the waste liquid circulation filtration and volatilization are ensured.

[0028] Optionally, the collecting tank and the second cavity are in communication, and a gas solvent for dissolving the volatile gas is arranged in the collecting tank.

[0029] By adopting the above technical scheme, the setting of the collecting tank and the gas solvent facilitates the recovery of the volatile gas.

[0030] Optionally, a stirring member is arranged in the waste liquid stirring tank, and the stirring member is used to stir the waste liquid uniformly.

[0031] By adopting the above technical scheme, the stirring member can uniformly distribute the solid particles in the waste liquid, prevent them from gathering or depositing at the bottom, and ensure the uniformity of the waste liquid in the subsequent filtration process, thereby avoiding the blockage of the filter member. In addition, by uniform stirring, the volatile substances in the waste liquid can be more uniformly distributed in the waste liquid, thereby increasing the gas-liquid contact area in the volatilization process. This can improve the volatilization efficiency and make the volatilization process more thorough and efficient.

[0032] Optionally, the stirring member comprises:

[0033] A servo motor is fixedly connected with the waste liquid stirring tank, the servo motor has a rotating shaft, and the rotating shaft penetrates through the waste liquid stirring tank;

DETAILED DESCRIPTION

[0048] It should be noted that in the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0049] The present application discloses a laundry liquid waste recycling device.

[0050] Embodiment 1: Figures 1-3 A laundry liquid waste recycling device includes a waste liquid stirring tank 1, a volatile gas extraction box 2, a volatile promoting assembly 3, a filter 4 and a collection box 5.

[0051] Reference Figure 1 And Figure 2 The waste liquid stirring tank 1 is located on the left side, and a first cavity 11 for containing waste liquid and an outlet 12 for liquid outlet are formed in the inside. A stirring member is coaxially arranged inside the waste liquid stirring tank 1, which includes a servo motor 14 above the waste liquid stirring tank 1 and a spiral blade 15. The servo motor 14 is fixedly connected with the waste liquid stirring tank 1, and the servo motor 14 has a rotating shaft which rotates through the top wall of the waste liquid stirring tank 1. The spiral blades 15 are uniformly arranged on the rotating shaft.

[0052] Because there are many solid particles in the laundry liquid waste, long-term storage will cause the solid particles to deposit at the bottom of the waste liquid stirring tank 1. Therefore, the stirring member is arranged, the servo motor 14 is started, the rotating shaft starts to rotate, and the spiral blade rotates together. The rotation of the spiral blade produces upward and downward motion, thereby generating convection in the waste liquid, so that the solid particles in the waste liquid are uniformly stirred, facilitating subsequent filtration. In addition, through uniform stirring, the volatile substances in the waste liquid can be more uniformly distributed in the waste liquid, thereby increasing the gas-liquid contact area during the volatilization process. This can improve the volatilization efficiency and make the volatilization process more efficient.

[0053] Reference Figure 3, the second cavity and an inlet for liquid are arranged inside the volatile gas extraction box 2, a connecting pipe 21 is arranged between the inlet of the volatile gas extraction box 2 and the outlet 12 of the waste liquid stirring tank 1, one end of the connecting pipe 21 is located at the bottom of the waste liquid stirring tank 1, and the other end is located at the top of the volatile gas extraction box 2. A liquid inlet pump 13 is arranged on the connecting pipe 21, and the liquid inlet pump 13 is arranged at the bottom of the waste liquid stirring tank and used to drive the waste liquid to flow in the second cavity. A volatile promoting assembly 3 is arranged inside the gas extraction box, and the volatile promoting assembly 3 is arranged close to the inlet, the waste liquid flows through the volatile promoting assembly 3, and the volatile promoting assembly 3 can promote the volatilization of volatile gas in the waste liquid. The volatile promoting assembly includes a plurality of volatile plates 31 and a blower 32.

[0054] With reference to Figure 3 The volatile plate 31 is arranged in an inclined state relative to the bottom wall of the volatile gas extraction box 2, and the higher end thereof is closely connected to the inner wall of the extraction box. The volatile plate 31 is designed in a stepped type, which facilitates the self-flow of the waste liquid by using flow inertia, thereby achieving energy saving and environmental protection. The inclined arrangement of the volatile plate 31 not only enables the waste liquid to flow naturally, but also helps to guide the waste liquid to the inlet of the volatile gas extraction box 2, and effectively increases the contact area between the waste liquid and air, thereby promoting the release of volatile gas therein. At the same time, the volatile plate 31 can realize the filtration treatment of the waste liquid through the filter 4 in the filter groove, so as to ensure that the solid particles or other impurities heavier than the waste liquid can be smoothly filtered out by gravity while collecting the volatile gas, thereby improving the efficiency and quality of waste liquid treatment.

[0055] In addition, the three volatile plates 31 are arranged in a reciprocating zigzag shape inside the volatile gas extraction box 2, and the lowest point of each volatile plate 31 is close to and located on the highest point of the adjacent lower volatile plate 31. The zigzag design of the volatile plate 31 enables the waste liquid to flow reciprocally between the volatile plates 31, effectively increasing the contact between the waste liquid and the volatile plate 31, thereby improving the release efficiency of the volatile gas.

[0056] The volatile gas extraction box 2 is provided with a plurality of gas outlets, in this embodiment, three gas outlets, each of which is located between adjacent volatile plates 31. The bottom of the volatile plate 31 is smooth, and the smooth bottom surface facilitates the accumulation of the gas volatilized from the volatile plate 31 below the volatile plate 31 to the gas outlet of the volatile gas extraction box 2. In addition, the filter groove and the filter element 4 opened on each volatile plate 31 can effectively filter solid particles or other impurities in the waste liquid. Since the waste liquid flows back and forth between the volatile plates 31, the waste liquid can contact the filter element 4 more when passing through the filter groove, increasing the filtering effect. Further ensure that the volatile gas is collected at the same time, the solid particles or other impurities in the waste liquid are effectively filtered. In addition, the Z-shaped design saves the installation space of the volatile plate 31, and improves the volatile efficiency of the entire volatile gas extraction box 2.

[0057] The filter element 4 is a plurality of filter screens, and the mesh number of the plurality of filter screens gradually increases from the highest point to the lowest point of the volatile plate 31. A plurality of filter screens are used, and the mesh number of the filter screens gradually increases from the highest point to the lowest point of the volatile plate 31, thereby filtering solid particles of different sizes. Different density filter screens can correspond to different size particles, so that the filtering effect is more comprehensive and thorough, and the filter screen with gradually increasing mesh number can more effectively filter out smaller particles, thereby improving the filtering effect.

[0058] In addition, an activated carbon filter membrane is arranged before the volatile gas extraction box 2 and the circulating tank 6, further improving the filtering effect of the waste liquid. In addition, after multiple waste liquid filtration and volatilization, the filter screen and the activated carbon filter membrane on the volatile plate 31 need to be opened for regular cleaning to avoid affecting the filtering effect due to repeated use.

[0059] Referring to Figure 3 , the air blower 32 is arranged on the inner wall of the volatile gas extraction box 2, the air blower 32 has a blowing port, and the blowing port faces the volatile plate 31. In this embodiment, the air blower 32 is three, each air blower 32 is arranged near the lowest point of a volatile plate 31. The airflow is blown out from the air blower 32 and faces the volatile plate 31, so that the flow direction of the waste liquid is opposite to the airflow, thereby forming a gas-liquid convection, increasing the contact area between the waste liquid and the air, accelerating the release of the volatile gas in the waste liquid, and improving the recovery efficiency of the waste liquid. In addition, since the air blower 32 is close to the lowest point of the volatile plate 31, the airflow can directly cover the entire volatile plate 31, thereby promoting the release of the volatile gas in the waste liquid.

[0060] Referring to 3 and Figure 4The circulating tank 6 is connected with the volatile gas extraction tank 2 for collecting the volatile gas extracted from the waste liquid. The circulating tank 6 is provided with a circulating pipe 62 which is connected with the connecting pipe 21. The circulating pipe 62 is provided with a circulating pump 61 which is fixed on the circulating tank 6 for driving the waste liquid in the circulating tank 6 to circulate into the second cavity for volatilization. The circulating pump 61 extracts the waste liquid from the circulating tank 6 through the circulating pipe 62 and circulates into the second cavity through the connecting pipe 21, thereby continuously sending the waste liquid to the volatilization plate 31 to ensure the waste liquid circulating filtration and volatilization.

[0061] With reference to Figure 1 and Figure 5 The volatile gas extraction tank 2 is connected with a collecting tank 5 which is connected with the second cavity. The collecting tank 5 is provided with a gas solvent for dissolving the volatile gas. In this embodiment, the collecting tank 5 is three. The collecting tanks 5 are connected through the elbow pipes. One end of the elbow pipe is arranged at the bottom of one collecting tank 5 and the other end is connected with the top of the adjacent collecting tank 5. The gas extraction pump 51 is arranged between the collecting tank 5 and the volatile gas extraction tank 2. The gas extraction pump 51 is used for extracting the volatile gas from the gas outlet and driving the gas into the collecting tank 5. The gas enters the gas solvent from the bottom of the collecting tank 5, thereby being maximally dissolved to increase the dissolution efficiency. Through the arrangement of the collecting tank 5, the gas extraction pump 51 and the gas solvent, the volatile gas is easily recovered. In addition, after the volatile gas is dissolved in the gas solvent, it will not diffuse into the environment with the air flow, thereby reducing the pollution to the surrounding environment.

[0062] The implementation principle of the embodiment 1 of the present application is as follows: the waste liquid stirring tank 1 is used to firstly treat the waste liquid, and the stirring of the waste liquid is realized by the built-in servo motor 14 and the spiral blade 15. The servo motor 14 drives the rotation shaft and the spiral blade 15 to rotate, and generates upward and downward flow, so that the solid particles in the waste liquid are uniformly dispersed, the deposition is prevented, and the distribution of volatile substances is promoted. The waste liquid is transported from the stirring tank to the volatile gas extraction box 2 through the liquid inlet pump 13. In the box, the waste liquid flows through the volatile promoting assembly 3, such as the volatile plate 31 and the air blower 32. The contact area of the waste liquid with air during the flow is increased, and the release of volatile gas is promoted. The air blower 32 enhances the air flow, and further accelerates the volatilization process. In addition, different density filter screens are installed in the filter grooves on the volatile plate 31 during the volatile promotion process, which can filter out particles of different sizes in stages, so as to ensure that the waste liquid is fully filtered. The volatile gas released from the waste liquid is pumped to the collection box 5 through the gas outlet at the top of the volatile gas extraction box 2. In the collection box 5, the gas is dissolved by the gas solvent, and this process is promoted by the air pump 51, which ensures that the gas enters the solvent from the bottom, thereby increasing the dissolution efficiency and the utilization rate of the gas. The circulation box 6 is connected with the volatile gas extraction box 2, and the circulation pump 61 enables the treated waste liquid to return to the volatile gas extraction box 2 for further volatilization and filtration, so as to realize the recycling of the waste liquid, thereby saving resources and reducing the discharge of waste liquid.

[0063] Embodiment 2: Refer to Figure 6 , which is basically the same as embodiment 1, except that the structure of the volatile plate 31 is different.

[0064] The volatile plate 31 includes a plurality of volatile sections 312 and a plurality of filter sections 313, the volatile sections 312 are arranged at intervals with the filter sections 313, the particle filter grooves 311 are arranged on the filter sections 313, the filter sections 313 are parallel to the bottom wall of the volatile gas extraction box 2, and the volatile sections 312 are arranged obliquely relative to the bottom wall. The volatile sections 312 are arranged obliquely relative to the bottom wall, so that the flow rate of the waste liquid is increased when passing through the volatile sections 312. The waste liquid accelerated by the volatile sections 312 will impact the filter sections 313, so that more waste liquid can contact the filter screen, thereby increasing the impact of the waste liquid on the filter plate and improving the filtering effect of the particulate matter. In addition, more volatile gas will escape during the impact process, which is convenient for collection.

[0065] It should be noted that the servo motor 14 and the air pump 51 in the present embodiment are commercially available devices, which can be selected or customized according to actual needs. In the present application, we only use them, and do not improve their structure and function. The setting method, installation method and electrical connection method can be operated according to the requirements of the instruction manual, and will not be described here.

[0066] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
