Description

Technical Field

[0001] The utility model relates to the technical field of resin backwashing, in particular to a resin backwashing device. Background Art

[0002] Chromatographic separation technology is widely used in industrial production and manufacturing. After the chromatographic separation equipment has been running for a period of time, the chromatographic separation resin in its chamber needs to be backwashed regularly due to the continuous accumulation of material pollutants. However, due to the variety of pollutants, especially for some pollutants with a certain surface area, viscosity, or even wrapped on the outside of the resin, after backwashing, the stratification is not obvious and the pollutants are retained in the resin layer, which leads to poor resin backwashing effect.

[0003] In the prior art, scrubbing is usually performed with the aid of air, such as the patent publication number CN117599862A, which discloses a method of scrubbing with air; however, scrubbing with the aid of air alone results in insufficient turbulence, which is insufficient to completely decompose or remove the pollutants.

[0004] Based on the above description, there is an urgent need for a resin backwashing device that can fully clean pollutants. Utility Model Content

DETAILED DESCRIPTION

[0021] Example 1

[0022] See also Figures 1 to 3 The utility model provides the following technical solutions: a resin backwashing device, which is suitable for treating pollutants during the backwashing process.

[0023] Specifically, Figure 1 and Figure 2 As shown, a resin backwashing device includes a tank body 1, a flushing mechanism 2 and a scrubbing mechanism 3; the scrubbing mechanism 3 includes an air intake assembly 31, multiple crushing assemblies 32 and a separation assembly 33; the flushing mechanism 2 is arranged at the bottom of the tank body 1; the air intake assembly 31 is connected to the flushing mechanism 2; the separation assembly 33 is built inside the top of the tank body 1; the air intake assembly 31 is connected to the bottom of the tank body 1; the crushing assembly 32 is arranged between the flushing mechanism 2 and the separation assembly 33.

[0024] The specific implementation process is: install the flushing mechanism 2 inside the bottom of the tank body 1, flush multiple crushing components 32 into the tank body 1 through the inlet pipe 6 and the water supply pipe, further pass water to the flushing mechanism 2, and after pre-passing part of the backwash water, close the water valve, open the ventilation valve, and send air into the bottom of the tank body 1. After the air enters the tank body 1, pass water to the flushing mechanism 2 again, and disturb the inside of the tank body 1, so that the multiple crushing components 32 roll in the resin, and the pollutants in the resin and wrapped on the surface of the resin are crushed, so that after continuous flushing, the crushed pollutants float on the upper layer of the resin, thereby facilitating the separation of the resin, pollutants, and backwash water through the separation component 33.

[0025] In this embodiment, the air intake component 31 may only include an air intake pipe, and may further include an air compressor, which compresses the air and then sends it into the tank body 1 through the air intake pipe; with the help of the flowing water impact force of the flushing mechanism 2 and the disturbance of the air, the crushing component 32 can thoroughly crush and clean the pollutants in the resin and on the surface of the resin, and the use of compressed air can improve the disturbance effect.

[0026] Specifically, Figure 2 and Figure 3 As shown, the crushing assembly 32 includes a sphere 321 and a plurality of protrusions 322; the plurality of protrusions 322 are arranged outside the sphere 321. The sphere 321 includes an elastic shell 3211 and a hard shell 3212; the hard shell 3212 is arranged inside the elastic shell 3211. The protrusions 322 include longitudinal protrusions and a plurality of transverse protrusions; the plurality of transverse protrusions are arranged outside the longitudinal protrusions at intervals; the longitudinal protrusions are arranged outside the elastic shell 3211.

[0027] In this embodiment, the hard shell 3212 is made of corrosion-resistant hard materials such as hard silicone and plastic, and the elastic shell 3211 is made of corrosion-resistant elastic materials such as elastic silicone and PVC. By arranging the protrusion 322 on the outside of the elastic shell 3211, the protrusion 322 will not damage the resin while scrubbing the resin, and a reverse elastic force can be obtained, so that the crushing component 32 will rebound to another resin area after scrubbing the resin.

[0028] Among them, the interior of the hard shell 3212 is inflated, and the annular gap between the hard shell 3212 and the elastic shell 3211 can also be further inflated. Specifically, a gas with a lower density such as hydrogen can be selected, so that the crushing component 32 can float on the upper layer of the resin layer under the impact of the water flow after being crushed; wherein, the protrusion 322 includes a longitudinal protrusion and multiple transverse protrusions, which can increase the contact area with the resin and pollutants, thereby facilitating the full crushing of the pollutants.

[0029] Specifically, Figure 1 and Figure 2 As shown, the flushing mechanism 2 includes a water inlet pipe 21 and a water distribution screen 22; the water distribution screen 22 is arranged inside the bottom of the tank body 1; the water inlet pipe 21 passes through the tank body 1 and is connected to the water distribution screen 22; the air intake assembly 31 is connected to the water inlet pipe 21.

[0030] In this embodiment, the water sent into the water inlet pipe 21 is diverted by the water distribution screen 22, so that the multiple crushing components 32 can fully move in the resin.

[0031] Specifically, Figure 1 and Figure 2 As shown, the separation assembly 33 includes a cylinder 331 and an overflow bucket 332; the cylinder 331 is disposed inside the top of the tank 1; the expansion end of the overflow bucket 332 is connected to the bottom of the cylinder 331; the contraction end of the overflow bucket 332 is disposed inside the cylinder 331; the tank 1 is connected to the overflow bucket 332. The separation assembly 33 also includes a strap 333; the cylinder 331 is screwed to the tank 1 through the strap 333.

[0032] In this embodiment, in the tank body 1, after the backwash water is continuously introduced, the resin expands to near the top of the tank body 1, and the top of the tank body 1 is divided into a sewage overflow chamber and a pollutant resin chamber through the cylinder 331 and the overflow bucket 332. The backwash water overflows into the sewage overflow chamber through the overflow bucket 332 and is extracted through the pumping pipe 4; the broken pollutants floating on the upper layer of the resin and the broken components 32 are extracted through the extraction pipe 5, and the most distal broken pollutants are extracted again through the pumping pipe 4 along with the backwash water.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
