Description

Technical Field

[0001] This utility model relates to ceramic membranes, specifically, to a hollow fiber ceramic membrane. Background Technology

[0002] Ceramic membranes are symmetrical or asymmetrical membranes formed from inorganic ceramic materials through a special process. They possess functions such as separation, clarification, purification, concentration, and sterilization, and are widely used in wastewater treatment, food, beverage, plant (pharmaceutical) deep processing, biomedicine, fermentation, and fine chemicals. Ceramic membranes are mainly divided into two types: tubular ceramic membranes and flat-sheet ceramic membranes. Tubular ceramic membranes have a dense separation layer on their tube walls. Under pressure, the feed liquid flows inside or outside the membrane tube, allowing small molecules (or liquids) to permeate while large molecules (or solids) are retained. Flat-sheet ceramic membranes have a dense separation layer on their surface. Under certain pressure, when the feed liquid flows across the membrane surface, only water, inorganic salts, and small molecules are allowed to permeate, while suspended solids, colloids, and microorganisms are prevented from passing through.

[0003] Currently, in liquid filtration, the presence of solid particles in the liquid can damage the ceramic membrane, causing the ceramic membrane to lose its filtration function and thus affecting the effectiveness of liquid filtration.

[0004] Secondly, compared to organic membranes, ceramic membranes have lower loading density and higher production costs for the same floor space, resulting in larger equipment investments and making the technology difficult to promote.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a hollow fiber ceramic membrane to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A hollow fiber ceramic membrane includes a ceramic membrane filter element, which is detachably connected inside a filter cartridge. A detachable assembly is provided between the filter cartridge and the ceramic membrane filter element. The detachable assembly includes a fixing plate fixedly connected to the bottom of the inner surface of the filter cartridge. The fixing plate has a stepped groove that matches the ceramic membrane filter element. A first internal thread is provided on the top of the inner surface of the filter cartridge. The top of the ceramic membrane filter element is fixedly mounted on a top plate. A first external thread is provided on the bottom of the outer surface of the top plate. The first external thread matches the first internal thread. A vibration assembly is provided on the top plate. The filter cartridge is fixedly mounted on the inner surface of a housing via a connector. A particle collecting hopper is welded to the bottom of the housing. A particle discharge pipe is fixedly connected to the bottom of the particle collecting hopper. A particle discharge valve is fixedly provided on the particle discharge pipe. A cover plate is threadedly connected to the top of the housing. A water inlet pipe is fixedly installed on the top of the cover plate.

[0009] Furthermore, in order to allow solid particles on the surface of the filter cartridge to fall into the particle collection hopper, the vibration assembly includes a shock absorber fixedly connected to the top plate, the output end of the shock absorber being fixedly connected to the vibration box, and a vibrator being fixedly installed inside the vibration box.

[0010] Furthermore, to facilitate the removal of the cover plate, a second external thread is provided on the top of the outer surface of the housing, and a second internal thread is provided on the bottom of the inner surface of the cover plate, the second internal thread matching the second external thread.

[0011] Furthermore, to prevent the liquid from directly impacting the vibration chamber, support members are fixedly connected at equal intervals on the top of the inner surface of the cover plate, and a baffle is fixedly installed on the bottom of the support member.

[0012] Furthermore, in order to facilitate the removal of the filtered liquid, a water collection hopper is fixedly connected to the bottom end of the filter cartridge, and a water outlet pipe is fixedly connected to the bottom end of the water collection hopper, with one end of the water outlet pipe extending outside the particle collection hopper.

[0013] Furthermore, in order to improve the sealing between the stepped groove and the ceramic membrane filter element, a rubber gasket is provided between the stepped groove and the ceramic membrane filter element, and the rubber gasket is fixedly connected to the stepped groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Liquid enters the housing through the inlet pipe. The filter cartridge inside the housing can block solid particles in the liquid from entering the filter cartridge and damaging the ceramic membrane filter element. The filter cartridge protects the ceramic membrane filter element.

[0016] 2. The vibrator works in conjunction with the shock absorber. On the one hand, it vibrates the surface of the filter cartridge, causing solid particles on the surface of the filter cartridge to fall into the granulation hopper. The granulation valve on the granulation outlet pipe is opened to discharge the solid particles out of the granulation hopper, which can effectively prevent solid particles from clogging the filter cartridge and affecting its normal use. On the other hand, it causes the ceramic membrane filter element to vibrate, which can accelerate the filtration efficiency of the ceramic membrane filter element.

[0017] 3. By twisting the cover plate, remove the cover plate from the outer shell, exposing the filter cartridge to the outside. By twisting the top plate, under the action of the first external thread and the first internal thread, the top plate is twisted off the filter cartridge, thereby allowing the ceramic membrane filter element to be removed from the filter cartridge. This facilitates the cleaning of the ceramic membrane filter element and the filter cartridge, further improving the filtration effect of the ceramic membrane filter element.

The top of the outer shell 15 is threaded with a... The cover plate 20 and the outer shell 15 have a second external thread 19 on the top of their outer surfaces and a second internal thread 21 on the bottom of their inner surfaces. The second internal thread 21 matches the second external thread 19.

Liquid not filtered by the ceramic membrane filter element 1 is discharged through the drain pipe to the outside of the outer shell 15. In order to avoid the liquid directly impacting the vibration box 5, support members 23 are fixedly connected at equal intervals on the top of the inner surface of the cover plate 20.

[0039] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0040] In practical applications, liquid enters the housing 15 through the inlet pipe 22 and falls onto the baffle 24. The baffle 24 is designed to prevent damage to the vibration components caused by the impact of the liquid. The filter cartridge 7 inside the housing 15 can block solid particles in the liquid outside the filter cartridge 7. The unblocked liquid flows into the filter cartridge 7, where the ceramic membrane filter element 1 filters the liquid. The filtered liquid flows into the water collection hopper 12 and is then discharged through the outlet pipe 13. Liquid that is not filtered by the ceramic membrane filter element 1 is discharged through the drain pipe. Under the combined action of the vibrator 6 and the shock absorber 4, the solid particles outside the filter cartridge 7 vibrate on the surface of the filter cartridge 7 and fall into the particle collection hopper 16, opening the particle outlet. The particle discharge valve 18 on the pipe 17 discharges solid particles out of the particle collection hopper 16, which can effectively prevent solid particles from clogging the filter cartridge 7 and affecting the normal use of the filter cartridge 7. On the other hand, it causes the ceramic membrane filter element 1 to vibrate, which can accelerate the filtration efficiency of the ceramic membrane filter element 1. If it is necessary to clean the ceramic membrane filter element 1 and the filter cartridge 7, the cover plate 20 is twisted off the outer shell 15 to expose the filter cartridge 7. The top plate 2 is twisted off the filter cartridge 7 by the action of the first external thread 3 and the first internal thread 8, thereby allowing the ceramic membrane filter element 1 to be taken out of the filter cartridge 7, which facilitates the cleaning of the ceramic membrane filter element 1 and the filter cartridge 7 and further improves the filtration effect of the ceramic membrane filter element 1.
