Description

Technical Field

[0001] This utility model belongs to the field of environmental protection technology and equipment technology, and in particular relates to a waste liquid recovery device for the preparation of nonylbenzene alcohol ether. Background Technology

[0002] Nonoxynol ether is a nonionic surfactant belonging to the polyoxyethylene alkylphenol ether class of compounds. It reduces the surface tension of cell membranes and interferes with the integrity of cell membranes, thereby destroying the cell membranes of microorganisms such as sperm, bacteria, and viruses, leading to their inactivation or death. Therefore, it is widely used in disinfectants, cosmetics, and industrial applications.

[0003] In the preparation of nonoxynol ether, a variety of organic solvents or other auxiliary chemical reagents are used. These solvents and reagents may also be present in the waste liquid. Recycling these organic solvents can reduce the purchase cost of new solvents and reduce the difficulty of subsequent treatment.

[0004] Typically, the recycling process includes filters to remove unreacted solid particles and salt crystals that may be present in the waste liquid. However, existing filter cartridges are usually installed vertically. This causes impurities to easily accumulate at the bottom of the filter cartridge as it flows, quickly clogging it and affecting subsequent waste liquid filtration. Workers also need to frequently replace and clean the filter cartridges, increasing maintenance costs and operational burden. Therefore, a waste liquid recovery device for nonoxynol ether preparation is needed to solve these problems. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a waste liquid recovery device for the preparation of nonylbenzene alcohol ether, so as to solve the problems mentioned in the background art.

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

[0007] A waste liquid recovery device for the preparation of nonoxynol ether includes:

[0008] A filter includes a fixed cylinder, a filter cylinder, an umbrella-shaped plate, a fixed post, and a return spring. The filter cylinder is detachably installed inside the fixed cylinder, the fixed post is fixedly installed inside the filter cylinder, the umbrella-shaped plate is slidably disposed on the fixed post, and the side wall of the umbrella-shaped plate is in contact with the inner wall of the filter cylinder. The return spring is sleeved on the fixed post, and its two ends are respectively connected to the bottom wall of the filter cylinder and the lower end of the umbrella-shaped plate.

[0010] A condenser, which is connected to the salt distillation kettle via a pipeline;

[0011] A water pumping buffer tank is connected to the condenser pipeline.

[0012] In a further technical solution, the filter also includes a slider, which is movably disposed on the fixed column along the axial direction of the fixed column.

[0013] In a further technical solution, the inner wall of the fixed cylinder has a limiting ring, the upper end of the filter cylinder has a limiting ring, and the lower end face of the limiting ring is in contact with the upper end face of the limiting ring.

[0014] In a further technical solution, the fixed cylinder has a cylinder body and a cylinder cover, the cylinder cover is detachably placed on the upper end face of the cylinder body, and the limiting ring is formed on the inner wall of the cylinder body.

[0015] In a further technical solution, the fixing cylinder forms a plurality of spaced-apart first snap-fit ​​holes on the limiting ring, and the filter cylinder forms a plurality of spaced-apart second snap-fit ​​holes on the limiting ring. Each first snap-fit ​​hole is adapted to each second snap-fit ​​hole, and the first snap-fit ​​hole and the second snap-fit ​​hole have the same diameter. The fixing cylinder has a plurality of spaced-apart snap-fit ​​posts and rubber blocks on the lower end face of the cylinder cover, and the snap-fit ​​posts snap into the first snap-fit ​​holes and the second snap-fit ​​holes.

[0018] This invention features an umbrella-shaped plate and a return spring. A fixed column is fixedly installed inside the filter cylinder, and the umbrella-shaped plate is slidably mounted on the fixed column with its sidewalls fitting against the inner wall of the filter cylinder. The return spring is sleeved on the fixed column, with its two ends connected to the bottom wall of the filter cylinder and the lower end of the umbrella-shaped plate, respectively. The waste liquid to be recycled flows to the upper surface of the umbrella-shaped plate, where solid impurities remain. The filtered waste liquid flows through the sidewall of the filter cylinder and, under gravity, to the lower end of the cylinder. Under gravity, the umbrella-shaped plate and the solid impurities on its upper surface move downwards along the fixed column. At this point, the return spring is compressed, preventing impurities from directly depositing at the bottom of the filter cylinder and affecting its filtration effect, thus reducing maintenance costs.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] like Figures 1 to 4 As shown, this utility model embodiment provides a waste liquid recovery device for the preparation of nonoxynol ether, comprising:

[0029] Filter 1 includes a fixed cylinder 11, a filter cylinder 12, an umbrella-shaped plate 13, a fixed post 14, and a return spring 15. The filter cylinder 12 is detachably installed inside the fixed cylinder 11, the fixed post 14 is fixedly installed inside the filter cylinder 12, the umbrella-shaped plate 13 is slidably disposed on the fixed post 14, and the side wall of the umbrella-shaped plate 13 is in contact with the inner wall of the filter cylinder 12. The return spring 15 is sleeved on the fixed post 14, and the two ends of the return spring 15 are respectively connected to the bottom wall of the filter cylinder 12 and the lower end of the umbrella-shaped plate 13.

[0030] Salt steaming kettle 2 is connected to the fixed cylinder 11 via a pipe.

[0031] Condenser 3 is connected to salt distillation vessel 2 via a pipeline;

[0032] Pumping buffer tank 4 is connected to condenser 3 by a pipe.

[0033] In this embodiment, the waste liquid to be recycled flows to the upper end face of the umbrella-shaped plate 13. At this time, the solid impurities in the waste liquid remain on the upper end face of the umbrella-shaped plate 13 or the inner wall of the filter cylinder 12 above the umbrella-shaped plate 13. The filtered waste liquid flows through the side wall of the filter cylinder 12 and flows to the lower end of the cylinder body 112 under the action of gravity. As the waste liquid to be filtered continues to enter the filter cylinder 12, the solid impurities remaining on the umbrella-shaped plate 13 gradually increase. Under the action of gravity, the solid impurities on the umbrella-shaped plate 13 and the upper end face of the umbrella-shaped plate 13 move downward along the fixed column 14 axially. At this time, the return spring 15 is compressed. In this way, by setting the umbrella-shaped plate 13 and the return spring 15, impurities are prevented from being directly deposited at the bottom of the filter cylinder 12 and affecting the filtration effect of the filter cylinder 12, thus reducing maintenance costs.

[0034] Specifically, the filter 1 also includes a slider 16, which is movably disposed on the fixed post 14 along the axial direction of the fixed post 14. The upper end face of the slider 16 is attached to the lower end face of the umbrella-shaped plate 13, and the lower end face of the slider 16 is connected to the return spring 15.

[0035] In this embodiment, after the solid impurities on the upper surface of the umbrella-shaped plate 13 are removed, under the elastic force of the return spring 15, both the slider 16 and the umbrella-shaped plate 13 move away from the limit ring 121, eliminating the need for manual operation by workers and further reducing maintenance costs.

[0036] Specifically, the inner wall of the fixed cylinder 11 has a limiting ring 111, and the upper end of the filter cylinder 12 has a limiting ring 121, with the lower end face of the limiting ring 121 fitting against the upper end face of the limiting ring 111.

[0037] Specifically, the fixed cylinder 11 has a cylinder body 112 and a cylinder cover 113. The cylinder cover 113 is detachably placed on the upper end face of the cylinder body 112, and the limiting ring 111 is formed on the inner wall of the cylinder body 112.

[0038] Specifically, the fixed cylinder 11 has a plurality of spaced first snap-fit ​​holes 114 on the limiting ring 111, and the filter cylinder 12 has a plurality of spaced second snap-fit ​​holes 122 on the limiting ring 121. Each first snap-fit ​​hole 114 is adapted to each second snap-fit ​​hole 122. The first snap-fit ​​hole 114 and the second snap-fit ​​hole 122 have the same diameter. The fixed cylinder 11 has a plurality of spaced snap-fit ​​posts 115 and rubber blocks 116 on the lower end face of the cylinder cover 113. The snap-fit ​​posts 115 snap into the first snap-fit ​​holes 114 and the second snap-fit ​​holes 122.

[0039] In this embodiment, when the filter cartridge 12 needs to be cleaned after a period of use, the worker first moves the cover 113 away from the body 112 so that the locking post 115 and the rubber block 116 are both disengaged from the first locking hole 114 and the second locking hole 122; then the filter cartridge 12 can be removed for cleaning, which is simple to operate.

[0040] Specifically, the filter 1 also includes an insulation shell 17 and an insulation material 18. The insulation shell 17 is disposed outside the fixed cylinder 11, and the insulation material 18 is disposed inside the insulation shell 17 and is in contact with the outer wall of the fixed cylinder 11.

[0041] In this embodiment, by setting up the heat insulation shell 17 and the heat insulation material 18, the heat loss of the waste liquid inside the fixed cylinder 11 is reduced, the waste liquid is kept within a suitable filtration temperature range, the filtration process of the filter cylinder 12 is ensured to be smooth, and the filtration efficiency and throughput are improved.

[0042] The working principle of this utility model is as follows:

[0043] First, the waste liquid to be recycled enters the filter cylinder 12 through the feed inlet at the end away from the cylinder body 112 via the cylinder cover 113; under the action of gravity, the waste liquid flows to the upper end face of the umbrella plate 13, at which time the solid impurities in the waste liquid remain on the upper end face of the umbrella plate 13 or the inner wall of the filter cylinder 12 above the umbrella plate 13, and the filtered waste liquid flows through the side wall of the filter cylinder 12 and to the lower end of the cylinder body 112 under the action of gravity.

[0044] As the waste liquid to be filtered continuously enters the filter cartridge 12, the amount of solid impurities remaining on the umbrella-shaped plate 13 gradually increases. Under the action of gravity, the umbrella-shaped plate 13 and the solid impurities on the upper surface of the umbrella-shaped plate 13 move downward along the axis of the fixed column 14, at which time the return spring 15 is compressed. In this way, by setting the umbrella-shaped plate 13 and the return spring 15, impurities are prevented from being directly deposited at the bottom of the filter cartridge 12, thus affecting the filtration effect of the filter cartridge 12 and reducing maintenance costs.

[0045] The filtered waste liquid flows out from the discharge port at the end of the cylinder 112 away from the cylinder cover 113 and flows into the salt steaming kettle 2 through the pipe. The waste liquid is heated in the salt steaming kettle 2, causing the water in the waste liquid to evaporate and the concentration of the waste liquid to gradually increase. When the solution reaches or exceeds the saturation solubility of inorganic salts, the inorganic salts will precipitate out of the solution in solid form, thereby achieving the initial separation of inorganic salts and organic matter.

[0046] Meanwhile, the large amount of water vapor generated after the waste liquid is heated in the salt distillation kettle 2 passes through the condenser 3. The water vapor is cooled in the condenser 3 and condenses into liquid water, reducing the waste of water resources and environmental pollution. Subsequently, the condensed liquid water enters the pumping buffer tank 4, which is used to temporarily store this liquid water to balance the unstable water flow and provide a relatively stable and continuous water source for subsequent treatment or use (such as reuse, discharge or further treatment), avoiding the instability or efficiency reduction of downstream equipment (such as pumps and pipelines) due to fluctuations in the water flow.

[0047] When the filter cartridge 12 needs to be cleaned after a period of use, the worker first moves the cover 113 away from the body 112 so that the locking post 115 and the rubber block 116 are disengaged from the first locking hole 114 and the second locking hole 122; then the filter cartridge 12 can be removed for cleaning, which is simple to operate; after the solid impurities on the upper surface of the umbrella plate 13 are removed, under the elastic force of the return spring 15, the slider 16 and the umbrella plate 13 move away from the limit ring 121, which does not require manual operation by the worker and further reduces maintenance costs.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
