Description

Technical Field

[0001] The utility model relates to the technical field of brine treatment equipment, in particular to an environmentally friendly Kay membrane filter used in a brine process. Background Art

[0002] In the brine process, the Kai membrane filter is usually used for the concentration and purification of brine. During the use of the Kai membrane filter, the Kai membrane filter can help separate the water molecules in the brine from the salt molecules through the characteristics of its microporous membrane or ultrafiltration membrane to achieve the concentration of the brine, which helps to increase the salt concentration of the brine, making it easier to carry out subsequent crystallization and collection. At the same time, compared with the traditional evaporation concentration process, the use of the Kai membrane filter for the concentration and purification of brine can usually save energy because it can achieve the concentration of brine at a lower temperature, reduce energy consumption, and be more environmentally friendly;

[0003] The prior art with patent number CN 211644712 ​​U discloses: comprising a tank body, a crude brine storage tank and a refined brine storage tank, a filter membrane assembly is installed in the tank body, an overflow pipeline and a crude brine pipeline are installed in sequence from top to bottom on the left side of the tank body, and the other ends of the overflow pipeline and the crude brine pipeline extend into the crude brine storage tank. The fully automatic membrane filter used in the brine process achieves the advantages of good equipment operation, improved production environment, reduced maintenance costs and good fluid control characteristics. The utility model improves the selection of pneumatic butterfly valves, which not only greatly saves costs, but also greatly improves the production environment and solves the problem of short service life of the filter flexible valve;

[0004] The above patent document discloses a fully automatic membrane filter used in the brine process to solve the problem of damage to the inner tank caused by frequent opening and closing of the flexible valve; although the membrane filter of the above patent can solve the defects of the flexible valve in the membrane filter, it is found in the actual filtration of brine by the membrane filter that since the brine contains a large amount of salt and impurities, it is easy to cause scaling on the surface of the membrane, affecting the filtration effect. At the same time, the brine may contain microorganisms, organic matter or other particulate matter, which will adhere to the surface of the membrane, causing membrane contamination problems, which can easily reduce the filtration efficiency of the membrane filter and increase energy consumption and maintenance costs.

[0005] In summary, there is a need for an environmentally friendly membrane filter that can easily maintain the salt water filtration and concentration effect for a long time. Utility Model Content

Example

[0034] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0035] In order to enable the Kai membrane filter to achieve the function of maintaining the filtering effect for a long time, it is necessary to be able to collect and remove the impurities filtered and cleaned in the filter in real time. Therefore, this embodiment provides the following design:

[0036] A cleaning mechanism 4 is provided on one side of the installation frame 1 31 and the installation frame 2 33 for filtering salt water. The cleaning mechanism 4 includes a cleaning box 41, a mounting rod 42, a waveguide rod 43 and a motor 1 44. The cleaning box 41 is fixedly arranged on the side of the installation frame 1 31 and the installation frame 2 33. Two groups of cleaning boxes 41 are mirror-imaged. A mounting rod 42 is arranged between the cleaning boxes 41. A waveguide rod 43 is arranged on the outside of the mounting rod 42. Multiple groups of waveguide rods 43 are arranged on the outside of the mounting rod 42 at equal intervals. The side of the waveguide rod 43 is connected to the membrane filter element. The side of the filter 32 and the side of the filter screen 34 are in close contact, and a motor 44 is provided inside the cleaning box 41; the motor 44 is a vibration motor, and when the salt water solution backwashes the filter screen 34 and the membrane filter element 32, the motor 44 works to vibrate the mounting rod 42 and the waveguide rod 43, and the waveguide rod 43 transmits the vibration wave to the filter screen 34 and the membrane filter element 32, thereby assisting the impurities adsorbed and filtered on the surface of the filter screen 34 and the membrane filter element 32 to fall off, so as to improve the backwashing cleaning effect of the membrane filter;

[0037] In this embodiment, a collecting area is formed between the support plate 11 and the partition plate 12, and between the partition plate 12 and the partition plate 2 13. A collecting assembly 2 is provided inside the collecting area. The collecting assembly 2 includes a collecting cylinder 21, a slag discharge pipe 22 and a control valve 23.

A slag discharge pipe 22 is provided at the bottom of the collecting cylinder 21, and the slag discharge pipe 22 runs through the outside of the filter box 1. A control valve 23 is provided in the middle of the slag discharge pipe 22; after the impurities are cleaned on the surface of the filter screen 34 and the surface of the membrane filter element 32, the conical collecting cylinder 21 in the collecting assembly 2 will collect impurities in the brine solution, thereby facilitating the impurities filtered and purified by the filter mechanism 3 to be discharged from the membrane filter, which is beneficial to maintaining the cleanliness of the inside of the membrane filter;

[0038] The implementation principle of the second embodiment is as follows: when the auxiliary cleaning component 5 drives the salt solution to backwash the filter screen 34 and the membrane filter element 32, the motor 1 44 in the cleaning mechanism 4 works to vibrate the mounting rod 42 and the waveguide rod 43. The vibration of the mounting rod 42 and the waveguide rod 43 transmits the vibration wave to the filter screen 34 and the membrane filter element 32. Under the action of the vibration, the cleaning effect of the salt solution backwashing the filter screen 34 and the membrane filter element 32 can be improved.

[0039] After the brine solution backwashes the filter screen 34 and the membrane filter element 32, the cleaned impurities will settle downward and fall into the collection cylinder 21 in the collection component 2. The conical collection cylinder 21 will gather the impurities filtered and isolated in the brine solution, so that the impurities can be discharged from the membrane filter through the slag discharge pipe 22 at a later time.
