Description

Technical Field

[0001] The utility model relates to the technical field of chemical experiments, in particular to a special dialysis membrane auxiliary device for a fertilizer laboratory. Background Art

[0002] Dialysis is one of the most commonly used techniques for separating and purifying organic polymers in the laboratory. Dialysis is a separation and purification technique that separates small molecules from biomacromolecules by the principle that small molecules diffuse into water (or buffer) through a semipermeable membrane. The concentration gradient on both sides of the semipermeable membrane generates diffusion pressure, and salts and small molecules are continuously transferred out of the dialysis bag. Dialysis bags (dialysis membranes) made of semipermeable membranes are usually used for dialysis in laboratories.

[0003] The existing experimental dialysis bag 15 is usually filled with the sample to be dialyzed, and the openings of the dialysis bag at both ends are sealed by a special sealing clamp 16, and then put into water for dialysis treatment. However, due to buoyancy during the treatment process, the dialysis bag containing the sample usually floats on the surface of the water and cannot penetrate into the water, resulting in poor dialysis effect, long dialysis time and other problems. In addition, the waste water after the experiment is usually directly poured out for treatment, which will undoubtedly cause a waste of water resources in the process of a large number of experiments. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a dialysis membrane auxiliary device to solve the above problems.

[0005] The utility model is realized through the following technical scheme: a dialysis membrane auxiliary device specially used in fertilizer laboratories, comprising a heated magnetic stirrer and a dialysis tank, a magnetic rotor being placed in the dialysis tank, a sealing cover being provided on the top of the dialysis tank, a clamping mechanism being provided below the sealing cover, the clamping mechanism comprising a fixed shaft fixedly connected to the bottom of the sealing cover, a horizontal support rod being horizontally rotatably connected to the fixed shaft, and fixing clamps being respectively installed on the support rods at both sides of the fixed shaft.

[0006] In this solution, after the dialysis bag is sealed by the sealing clamp, the fixing clamp is clamped on the sealing clamps at both ends of the dialysis bag to fix the dialysis bag, and the sealing cover is covered on the dialysis tank so that the dialysis bag can be immersed in the water to prevent it from floating, thereby improving the dialysis effect. The heated magnetic stirrer drives the magnetic rotor to rotate to form a vortex, and the water rotation drives the support rod to rotate around the fixed axis, so that the dialysis bag follows the accelerated rotation, further accelerating the dialysis rate and further improving the dialysis effect.

[0007] As an optimization, the support rod includes a shaft sleeve and two cross bars fixedly connected to both sides of the shaft sleeve outer wall, the shaft sleeve is rotatably connected to the fixed shaft, and fixing clips are detachably fixed on the two cross bars. The fixing clips of this optimization solution are easy to disassemble and assemble.

[0008] As an optimization, a long hole is opened on the crossbar along the length direction, and a fixing bolt is passed through the long hole to be fixedly connected with the fixing clamp. The fixing clamp of this optimization solution can be moved along the long hole to adjust the clamping distance.

[0009] As an optimization, a water injection tank and a wastewater tank are also included, the dialysis tank is provided with a first water inlet and a first water outlet, the water injection tank is provided with a second water inlet and a second water outlet, the wastewater tank is provided with a third water inlet and a third water outlet, the first water inlet is connected to the second water outlet through a first water pump, and the first water outlet is connected to the third water inlet through a second water pump. This optimization scheme injects water from the water injection tank into the dialysis tank through the first water pump, and discharges wastewater in the dialysis tank into the wastewater tank through the second water pump, which is convenient to use.

[0010] As an optimization, the water injection tank is further provided with a fourth water inlet, a wastewater filter is provided between the fourth water inlet and the third water outlet, the water inlet end of the wastewater filter is connected to the third water outlet, and the water outlet end of the wastewater filter is connected to the fourth water inlet. This optimization scheme filters the wastewater discharged from the wastewater tank through the wastewater filter and outputs it to the water injection tank for recycling, thereby improving the utilization rate of water resources.

[0011] As an optimization, an activated carbon filter layer and a small molecule filter layer are provided in the wastewater filter. In this solution, the activated carbon filter layer filters salt impurities in the wastewater, and the small molecule filter layer filters small molecules in the wastewater.

[0012] As an optimization, the water injection tank, waste water tank and waste water filter are all fixedly mounted on the mobile frame. This solution is convenient for disassembly, assembly and movement.

[0013] As an optimization, a temperature sensor is provided in the dialysis tank. This optimization detects the temperature of the water in the dialysis tank through the temperature sensor.

[0014] As an optimization, a conductivity meter is provided in the dialysis tank. This optimization scheme detects the conductivity value in the water through the conductivity meter to monitor the water purity.

[0015] The beneficial effects of the utility model are as follows: the sealing clamp of the dialysis bag is clamped and fixed by the fixing clamp on the support rod and immersed in the water, and the support rod is driven to rotate around the fixed axis by the rotation of the water, which greatly improves the dialysis rate and the dialysis effect; the waste water after dialysis is filtered through the waste water filter and then re-injected into the water injection tank for recycling, saving water resources.
