Description

Technical Field

[0001] The utility model relates to a material cleaning device. Background Art

[0002] Chromatographic fillers usually refer to microsphere materials with nanopore structures. The particle size is on the micrometer scale, and the pore size of the nanopores on the fillers is in the range of 5-200 nanometers.

[0003] The performance of chromatographic packing depends on its morphology, structure, particle size and distribution, pore size and distribution, material composition and surface functional groups.

[0004] According to the chromatographic separation mode, the fillers can be divided into normal phase chromatography fillers, reverse phase chromatography fillers, hydrophilic chromatography fillers, hydrophobic chromatography media, ion exchange chromatography media, affinity chromatography media, and size exclusion chromatography media.

[0005] The matrix of chromatographic packing can be mainly divided into inorganic media and organic polymers, among which organic polymers include natural polymers and synthetic polymers. Some materials are relatively viscous and easily stick to the stainless steel filter mesh, causing the filter mesh to be blocked, resulting in a poor filtering effect.

[0006] In addition, the traditional cleaning device is an open container with a layer of net inside. The filler is directly pumped into it with a pump. The bottom valve is closed first. After the material fills the can, the bottom valve is opened to pump out the water. This requires manual turning, and the process is relatively cumbersome. Utility Model Content

[0007] In view of the above problems, the purpose of the utility model is to provide a material cleaning device that can prevent the filter from being blocked.

[0008] The technical solution to realize the utility model is as follows

[0009] A material cleaning device comprises a tank body, a stirring assembly is arranged in the center of the tank body, a water inlet and a feed port are arranged at one end of the top surface of the tank body, and a backwash outlet is arranged at the other end; two opposite backwash inlets are arranged on the conical side of the bottom of the tank body, and a filter screen is arranged at the bottom of the tank body between the tank stirring assembly and the backwash inlet.

[0010] The stirring assembly comprises a motor and a stirring rod connected to the motor. The bottom surface of the stirring rod is provided with a plurality of stirring blades; and a plurality of teeth are evenly distributed on the stirring blades.

[0011] The bottom end of the tank body is connected to the screw pump through a control valve, and a drainage port is also arranged on the bottom surface of the tank body.

[0012] The backwash water outlet comprises a water outlet pipe, and a filter screen is arranged at the bottom of the water outlet pipe; the water outlet pipe is inserted into the tank body and is located at the bottom of the tank body.

[0013] The filter screen is a stainless steel filter screen.

[0014] A stirring blade is sleeved at the center of the stirring rod.

[0015] By adopting the above technical solution, the backwash water inlet is facing the middle of the filter screen, and the backwash water inlet is facing the middle section of the filter screen for flushing. The flushing coverage is wider and the flushing effect is better. The solids on the filter screen can be flushed out of the filter screen to keep the filter screen unobstructed.

[0017] In the accompanying drawings, 1 is a tank body, 2 is a stirring assembly, 4 is a feed port, 5 is a backwash outlet, 6 is a backwash inlet, 7 is a filter screen, 8 is a motor, 9 is a stirring rod, 10 is a stirring blade, 11 is a tooth, 12 is a control valve, 13 is a screw pump, 14 is a drain port, 15 is a water outlet pipe, 16 is a filter screen, and 17 is a stirring blade. DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] A material cleaning device comprises a tank body 1, a stirring assembly 2 is arranged in the center of the tank body, a water inlet and a feed inlet 4 are arranged at one end of the top surface of the tank body, and a backwash outlet 5 is arranged at the other end; two opposite backwash inlets 6 are arranged on the conical side of the bottom of the tank body, and a filter screen 7 is arranged at the bottom of the tank body between the tank body stirring assembly and the backwash inlet. The backwash inlet faces the middle of the filter screen, and the backwash inlet faces the middle section of the filter screen for flushing, so that the flushing coverage is wider and the flushing effect is better, and the solids on the filter screen can be flushed out of the filter screen to keep the filter screen unobstructed.

[0020] The stirring assembly includes a motor 8, a stirring rod 9 connected to the motor, and a plurality of stirring blades 10 are arranged on the bottom of the stirring rod; the stirring blades are evenly distributed with a plurality of teeth 11. The motor drives the stirring blades to stir the material. Since the filler is relatively viscous, the part stuck on the net needs to be slowly pushed away, and the tooth-shaped stirring is convenient for pushing away.

[0021] The bottom end of the tank is connected to a screw pump 13 via a control valve 12, and a drain port 14 is provided on the bottom surface of the tank. The discharge is controlled by the cooperation of the control valve and the screw pump.

[0022] The backwash outlet includes an outlet pipe 15, and a filter screen 16 is provided at the bottom of the outlet pipe; the outlet pipe is inserted into the tank body and is located at the bottom of the tank body. Since the bottom of the outlet pipe is located below the tank body, the tank body can be drained when there is a small amount of liquid. In order to prevent the filter screen from being blocked, it is necessary to backwash from the other side of the filter screen during cleaning. If too much water enters, the water will overflow from the top port 15, and the filler cannot pass through.

[0023] The filter screen is a stainless steel filter screen and has a long service life.

[0024] The center of the stirring rod is also provided with a stirring blade 17. A group of stirring blades is provided in the middle of the stirring rod, and a group of stirring blades is provided at the bottom, so that the material is stirred more evenly.

[0025] Here's the usage process:

[0026] Step 1, a filler liquid containing an organic solvent and water enters from a feed port;

[0027] Step 2, water and some organic solvents will be discharged from the drain;

[0028] Step 3, at this time, the solid part will be retained on the stainless steel filter;

[0029] Step 4, start to let water in from the water inlet; (open the bottom water outlet, discharge water, adjust the bottom valve opening, the water inlet at the top needs to be greater than the water outlet at the bottom, and after water overflows from the backwash water outlet at the bottom, the water inlet valve needs to be closed)

[0030] Step 5, turn on the stirring at the same time and start to allow the water to fully flush the solid filler in the tank;

[0031] Step 6: During the drainage process, the stainless steel mesh will be blocked by solids. At this time, you can open the two backwash inlets for backwashing;

[0032] Step 7, the drain outlet continues to discharge, and the operation is repeated several times (since sampling verification is generally required, the residual concentration of organic solvents, but after the verification is completed, each batch only needs to be flushed for a fixed period of time).

[0033] Step 8, when the organic solvent residue meets certain requirements, open the bottom valve and the bottom screw pump to start discharging.
