Description

Technical Field

[0001] This utility model relates to the field of phosphate ester treatment technology, and in particular to a highly efficient device for concentrating organic phosphate esters in water. Background Technology

[0002] Organophosphates in water are phosphorus-containing organic compounds widely used as pesticides, flame retardants, plasticizers, etc. They enter water bodies through industrial wastewater, agricultural discharge, and atmospheric deposition. Because their concentration in water is extremely low, direct detection is difficult. Therefore, concentration treatment is required to increase the concentration and meet the sensitivity requirements of instrumental analysis, so as to accurately determine their content and provide data support for environmental monitoring and pollution control.

[0003] However, the concentration of organophosphates in water is extremely low, and traditional single-layer adsorption filtration has poor adsorption capacity and is prone to missing organophosphates, resulting in inaccurate data. Furthermore, organophosphates exist in both dissolved and adsorbed states, and simply using adsorption filtration can easily lead to the omission of dissolved organophosphates.

[0004] Therefore, we provide a highly efficient device for concentrating organic phosphate esters in water to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a device for highly efficient concentration of organic phosphate esters in water.

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

A separation assembly is disposed on the inner side of the conical-bottom separation tank. The separation assembly includes a magnetic adsorption ring installed on the inner side of the top of the conical-bottom separation tank. A flow guide plate is disposed on the inner wall of the conical-bottom separation tank. A tank bottom is welded to the bottom of the conical-bottom separation tank.

A highly efficient phosphate ester concentration assembly is disposed on the outer side of the conical-bottom separation tank. The highly efficient phosphate ester concentration assembly includes a pump connected to the outer wall of the conical-bottom separation tank. A filter sampling tube is connected to the outer side of the pump. A delivery tube is connected to one side of the filter sampling tube. A tube cap is bolted to the top of the filter sampling tube.

[0008] As a further description of the above technical solution:

[0009] The magnetic adsorption ring is connected to the inner top of the cone-bottom separation tank by a slot. The magnetic adsorption ring has a ring structure and the inside of the magnetic adsorption ring is a neodymium iron boron magnetic core.

[0010] As a further description of the above technical solution:

[0011] A primary filter disc is provided on the lower side of the magnetic adsorption ring, a secondary filter disc is provided on the lower side of the primary filter disc, and a tertiary filter disc is provided on the lower side of the secondary filter disc. The primary, secondary, and tertiary filter discs are arranged in a stepped manner, and the primary, secondary, and tertiary filter discs are all in close contact with the conical bottom separation tank.

[0012] As a further description of the above technical solution:

[0013] The elastic extrusion membrane is located between the bottom of the tank and the bottom cover. The elastic extrusion membrane is made of porous silicone material. A reciprocating air pressure pump is installed on the upper left side of the tank cover. The reciprocating air pressure pump generates air pressure to extrude the elastic extrusion membrane through the conical bottom separation tank.

[0014] As a further description of the above technical solution:

[0015] A rotary motor is installed on the upper left side of the can lid, and a stirring rod is connected to the lower shaft of the rotary motor. The rotary motor is located at a non-central position of the can lid, and the stirring rod and the guide plate generate an asymmetric vortex.

[0016] As a further description of the above technical solution:

[0017] The liquid pump is located between the secondary and tertiary filter discs. The liquid pump is connected to the filter sampling tube by a pipeline, and the infusion tube is connected to the bottom cover by a pipeline. The infusion tube and the bottom cover are supplied with liquid by a reciprocating air pressure pump.

[0018] As a further description of the above technical solution:

[0019] The inner groove of the tube cap is connected to a squeezing rod. Hydraulic pump rods are welded to both the front and rear sides of the filter sampling tube. A folded enrichment column is installed at the bottom of the filter sampling tube. An outlet is installed on the lower side of the filter sampling tube. The hydraulic pump rod drives the squeezing rod to reciprocate along the filter sampling tube. The folded enrichment column is filled with a foldable C18 filter membrane.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model utilizes a separation component that employs a stepped filtration process involving a primary, secondary, and tertiary filter disc. The pore size of the three filter discs decreases progressively, ensuring effective interception of minute particles and residues in the water, thus improving separation purity. As a reciprocating air pump injects air into the conical bottom separation tank, the air pressure compresses the elastic extrusion membrane, causing it to undergo diffusion deformation. Because the elastic extrusion membrane is made of silicone, its surface pores are opened during deformation, thereby squeezing out the deposited particles at the bottom of the conical bottom separation tank and expelling interstitial water. Organic phosphate molecules that can be adsorbed by the deposited particles are retained, while those carried by the interstitial water are discharged with the water, further enhancing the separation effect. A rotary motor drives the stirring rod to rotate, and a guide plate guides the water flow to form a vortex, enhancing the mixing effect. Furthermore, because the rotary motor is located off-center, it avoids dead zones in one direction of stirring, ensuring uniform mixing of the liquid in the tank and improving separation efficiency.

[0022] 2. This utility model utilizes a phosphate ester high-efficiency concentration component. With the reciprocating pneumatic pump, liquid is squeezed into the filter sampling tube through the infusion tube. Meanwhile, the pump between the secondary and tertiary filter discs directly draws the filtered liquid into the filter sampling tube for subsequent filtration. The hydraulic pump rod drives the squeezing rod to adjust its height, thereby causing the folded enrichment column to extend and retract. The C18 filter membrane filled inside the folded enrichment column is made of multi-layer composite material, which effectively traps fine particles. Furthermore, the enrichment efficiency can be adjusted by changing the height of the folded enrichment column. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 As shown, this utility model provides a technical solution: a high-efficiency concentration device for organic phosphate esters in water, including a conical bottom separation tank 1, a separation component 2 provided on the inner side of the conical bottom separation tank 1, the separation component 2 including a magnetic adsorption ring 201 installed on the inner side of the top of the conical bottom separation tank 1, a guide plate 205 provided on the inner wall of the conical bottom separation tank 1, a tank bottom 206 welded to the bottom of the conical bottom separation tank 1, an elastic extrusion membrane 207 provided on the inner side of the tank bottom 206, a bottom cover 208 installed on the lower side of the tank bottom 206, a tank cover 209 connected to the upper side of the conical bottom separation tank 1 by a slot, and a high-efficiency concentration component 3 for phosphate esters provided on the outer side of the conical bottom separation tank 1, the high-efficiency concentration component 3 for phosphate esters including a pump 301 connected to the outer wall of the conical bottom separation tank 1, a filter sampling tube 302 connected to the outer side of the pump 301, an infusion tube 303 connected to one side of the filter sampling tube 302, and a tube cap 304 bolted to the top of the filter sampling tube 302.

[0032] Furthermore, the magnetic adsorption ring 201 is connected to the inner top of the cone-bottom separation tank 1 by a slot. The magnetic adsorption ring 201 has a ring structure and a neodymium iron boron magnetic core inside. When needed, the magnetic nano-adsorbent is poured into the cone-bottom separation tank 1. When water containing organic phosphates is poured into the cone-bottom separation tank 1, the magnetic nano-adsorbent quickly adsorbs the organic phosphates. Through the magnetic material, the magnetic nano-adsorbent containing organic phosphates is adsorbed onto the magnetic adsorption ring 201, achieving efficient separation. When the magnetic adsorption ring 201 accumulates to a certain extent on its surface, an external antimagnetic magnetic ring can be used to demagnetize the magnetic adsorption ring 201. Subsequently, the magnetic nano-adsorbent will fall to the bottom of the cone-bottom separation tank 1, achieving the effect of concentration.

[0033] Furthermore, a primary filter disc 202 is disposed below the magnetic adsorption ring 201, a secondary filter disc 203 is disposed below the primary filter disc 202, and a tertiary filter disc 204 is disposed below the secondary filter disc 203. The primary filter disc 202, secondary filter disc 203, and tertiary filter disc 204 are arranged in a stepped manner. The primary filter disc 202, secondary filter disc 203, and tertiary filter disc 204 are all tightly fitted to the cone-bottom separation tank 1. When needed, the primary filter disc 202, secondary filter disc 203, and tertiary filter disc 204 undergo stepped filtration, and the pore size of the three filter discs decreases step by step to ensure that tiny particles and residues in the water are effectively intercepted, thereby improving the separation purity.

[0034] Furthermore, the elastic extrusion membrane 207 is located between the tank bottom 206 and the bottom cover 208. The elastic extrusion membrane 207 is made of porous silicone. A reciprocating air pump 212 is installed on the upper left side of the tank cover 209. The reciprocating air pump 212 generates air pressure to extrude the elastic extrusion membrane 207 through the conical bottom separation tank 1. When it is needed, as the reciprocating air pump 212 injects air into the conical bottom separation tank 1, the air pressure will squeeze the elastic extrusion membrane 207, thereby causing the elastic extrusion membrane 207 to undergo diffusion deformation. Since the elastic extrusion membrane 207 is made of silicone, the pores on the surface will be opened during the deformation process, thereby squeezing the deposited particles at the bottom of the conical bottom separation tank 1 and squeezing out the interstitial water. The organic phosphate molecules that can be adsorbed by the deposited particles are retained, while the organic phosphate molecules carried by the interstitial water are discharged with the water, further improving the separation effect.

[0035] Furthermore, a rotary motor 210 is installed on the upper left side of the tank lid 209. A stirring rod 211 is connected to the lower shaft of the rotary motor 210. The rotary motor 210 is located in a non-central position of the tank lid 209. The stirring rod 211 and the guide plate 205 generate an asymmetric vortex. When needed, the rotary motor 210 drives the stirring rod 211 to rotate, and the guide plate 205 guides the water flow to form a vortex, which enhances the mixing effect. Since the rotary motor 210 is in a non-central position, it can avoid dead zones of stirring in one direction, ensure that the liquid in the tank is mixed evenly, and improve the separation efficiency.

[0036] Furthermore, the liquid pump 301 is located between the secondary filter plate 203 and the tertiary filter plate 204. The liquid pump 301 is connected to the filter sampling tube 302 by a pipeline, and the infusion tube 303 is connected to the bottom cover 208 by a pipeline. The infusion tube 303 and the bottom cover 208 are supplied with liquid by squeezing through the reciprocating air pump 212. When needed, as the reciprocating air pump 212 reciprocates, the liquid is squeezed into the filter sampling tube 302 through the infusion tube 303. The liquid pump 301, located between the secondary filter plate 203 and the tertiary filter plate 204, directly draws the filtered liquid into the filter sampling tube 302 for subsequent filtration.

[0037] Furthermore, a squeezing rod 305 is connected to the inner groove of the tube cap 304. Hydraulic pump rods 306 are welded to both the front and rear sides of the filter sampling tube 302. A folded enrichment column 307 is installed at the bottom of the filter sampling tube 302. An outlet 308 is installed on the lower side of the filter sampling tube 302. The hydraulic pump rod 306 drives the squeezing rod 305 to reciprocate along the filter sampling tube 302. The folded enrichment column 307 is filled with a foldable C18 filter membrane. When needed, the hydraulic pump rod 306 drives the squeezing rod 305 to adjust its height, thereby causing the folded enrichment column 307 to extend and retract. The C18 filter membrane filled inside the folded enrichment column 307 is made of multi-layer composite material, which effectively traps fine particles. The enrichment efficiency can be adjusted by adjusting the height of the folded enrichment column 307.

[0038] Working Principle: When needed, first place the conical bottom separator 1 in the desired position, then pour the magnetic nano-adsorbent into the conical bottom separator 1, followed by water. After preparation, seal the top of the conical bottom separator 1 with the lid 209. At this time, the rotary motor 210 drives the stirring rod 211 to stir and rotate, allowing the magnetic nano-adsorbent and the organic phosphate particles in the water to mix thoroughly. Since the rotary motor 210 is in a non-central position, it can generate an asymmetric vortex in the conical bottom separator 1 in conjunction with the guide plate 205, improving mixing efficiency. The magnetic particles containing organic phosphate particles are captured by the magnetic adsorption ring 201. When the captured amount is large, pressure can be applied to the magnetic adsorption ring 201 through an external antimagnetic ring, thereby releasing the magnetic particles. As mixing progresses, particulate impurities are filtered through a three-stage process: primary filter plate 202, secondary filter plate 203, and tertiary filter plate 204, classifying and intercepting the substances. The substances that are not intercepted will fall into the water. When water enters the conical bottom separator 1 at tank bottom 206, the reciprocating air pump 212 injects air pressure into the separator, causing the elastic compression membrane 207 to expand and drain interstitial water through the central hole. This water is then sent to the filter sampling tube 302 via the infusion pipe 303 connected to the bottom cover 208. Particulate matter is intercepted by the elastic compression membrane 207. The pump 301 then draws water from between the secondary filter plate 203 and the tertiary filter plate 204 and sends it to the filter sampling tube 302. The folded enrichment column 307 inside 02 will play an enrichment and filtration role. The water with adsorbed organic phosphate esters will be discharged from the outlet 308, while the organic phosphate esters will be captured by the folded enrichment column 307. According to the enrichment state of the folded enrichment column 307, the squeezing rod 305 in the middle of the tube cover 304 can drive the folded enrichment column 307 through the hydraulic pump rod 306 to adjust the fold density, thereby adjusting the enrichment efficiency. This completes the use process of a high-efficiency concentration device for organic phosphate esters in water.
