Description

Technical Field

[0001] The utility model relates to the technical field of tangential flow ultrafilters, in particular to an improved tangential flow ultrafilter. Background Technique

[0002] Ultrafilters are key equipment on electrophoretic coating lines. Tube ultrafilters and spiral wound ultrafilters are widely used on electrophoretic lines. Ultrafiltration of ultrafilters, also known as crossflow filtration, is used to retain colloidal-sized particles in water, while water and low-molecular-weight solutes are allowed to pass through the membrane. The mechanism of ultrafiltration refers to the combined effect of mechanical sieving on the membrane surface, pore blockage, and adsorption on the membrane surface and pores, with sieving as the main mechanism.

[0003] For example, a laboratory tangential flow ultrafilter with the authorization announcement number of "CN212167073U" has a frustum-shaped tube head with different outer diameters at each place, so as to be connected to external conduits of different thicknesses, with stronger adaptability. And the anti-slip patterns provided effectively improve the stability when the tube head is connected to the external conduit, increasing the friction force, which is beneficial to avoiding the problem of slippage during use. However, in the above, bolts are used to fix the bottom box and the box cover. Since multiple groups of bolts are set, when fixing them, the staff needs to repeatedly turn the bolts, and this operation is too cumbersome and the working speed is slow. And the tube head is connected to the external conduit by means of plugging. When the water flow is rapid, the sealing performance is poor, resulting in water leakage and reducing the use quality. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that when multiple groups of bolts are set for fixing, the staff needs to repeatedly turn the bolts, which is too cumbersome and the working speed is slow, and when the tube head is connected to the external conduit by means of plugging, the sealing performance is poor when the water flow is rapid, resulting in water leakage and reducing the use quality, and to propose an improved tangential flow ultrafilter.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] Design an improved tangential flow ultrafilter, including a first outer shell and a second outer shell. The outer walls of the first outer shell and the second outer shell are sealed and connected by a rubber pad. An ultrafiltration tube is fixed in the first outer shell and the second outer shell by a bracket. Tangential flow ultrafilter housing fixing structures are arranged on both sides of the outer wall of the first outer shell, and two ultrafiltration tube connection limiting structures are arranged at the left end of the outer wall of the first outer shell.

[0007] Preferably, the two tangential flow ultrafilter housing fixing structures include a straight rod, a square plate, and a concave plate. A first clamping block is fixedly connected to the outer wall of the straight rod, a second clamping block is fixedly connected to the end of the straight rod, and the outer wall of the straight rod is slidably connected to the square plate and the concave plate.

[0008] Preferably, the outer wall of the square plate is fixedly connected to the outer wall of the first housing, and the outer wall of the concave plate is fixedly connected to the outer wall of the second housing.

[0009] Preferably, the two ultrafiltration tube connection limiting structures include a conical tube. The outer wall of the conical tube is sleeved with a horizontal tube. A rubber ring is fixedly connected inside the horizontal tube. A hoop is sleeved on the protruding parts of the outer walls of the horizontal tube and the conical tube. Blocks are fixedly connected to both ends of the hoop. Both of the two blocks are threadedly connected to bolts.

[0010] Preferably, the right end of the outer wall of the conical tube penetrates through the first housing and the second housing, and the two conical tubes are respectively communicated with both ends of the ultrafiltration tube.

[0011] An improved tangential flow ultrafilter proposed by the present utility model has the beneficial effects that: through the cooperation of the tangential flow ultrafilter housing fixing structure and the housing, the two horizontal tubes are respectively sleeved on the outer wall of the conical tube. Rubber rings are fixedly connected to the inner walls of the two horizontal tubes to prevent water leakage during water source transportation. Subsequently, the hoop is sleeved on the protruding parts of the outer walls of the horizontal tube and the conical tube. Align the blocks fixed to both ends of the hoop, and then rotate the bolts downward to fix the two blocks, thereby fixing the horizontal tube and the conical tube through the hoop. Using the hoop and the stud to limit and hold the horizontal tube and the conical tube can improve the sealing performance, avoid poor sealing performance and water leakage caused by rapid water flow in the prior art, and improve the use quality.

[0012] Through the ultrafiltration tube connection limiting structure, insert the straight rod and the second block into the openings processed in the middle of the square plate and the concave plate. When the straight rod drives the first block to abut against the outer wall of the square plate, rotate the straight rod to drive the first block to rotate synchronously. Since the concave plate surface is processed with protruding parts, the square plate and the concave plate will relatively gather when the first block rotates, thereby driving the first housing and the second housing to relatively gather through the square plate and the concave plate. Use the straight rod to drive the second block to rotate to make the square plate and the concave plate relatively gather, thereby driving the first housing and the second housing to relatively gather to fix the ultrafiltration tube. There is no need for the staff to repeatedly rotate the bolts to fix the bottom box and the box cover in the prior art. After the improvement, the operation is more convenient and the working speed is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Referring to the attached Figures 1-7 : In this embodiment, an improved tangential flow ultrafilter includes a first outer shell 3 and a second outer shell 4. The outer walls of the first outer shell 3 and the second outer shell 4 are hermetically connected through a rubber pad 5. An ultrafiltration tube 6 is fixed inside the first outer shell 3 and the second outer shell 4 through a bracket. The working mode of the ultrafiltration tube 6 is the prior art and will not be elaborated here. Two tangential flow ultrafilter housing fixing structures 2 are provided on both sides of the outer wall of the first outer shell 3;

[0023] Two ultrafiltration tube connection limiting structures 1 are provided at the left end of the outer wall of the first outer shell 3. The outer wall of the square plate 204 is fixedly connected to the outer wall of the first outer shell 3. The outer wall of the concave plate 205 is fixedly connected to the outer wall of the second outer shell 4. The right end of the outer wall of the conical tube 105 penetrates through the first outer shell 3 and the second outer shell 4, and the two conical tubes 105 are respectively communicated with both ends of the ultrafiltration tube 6.

[0024] Referring to the attached Figures 1-3 and FIGS. 5 - 7: The two tangential flow ultrafilter housing fixing structures 2 include a straight rod 201, a square plate 204, and a concave plate 205. A first clamping block 202 is fixedly connected to the outer wall of the straight rod 201. A second clamping block 203 is fixedly connected to the end of the straight rod 201. The outer wall of the straight rod 201 is slidably connected to the square plate 204 and the concave plate 205, and the straight rod 201 can slide inside the square plate 204 and the concave plate 205.

[0025] Referring to the attached Figures 1-4: The connection limiting structure 1 of two ultrafiltration tubes includes a conical tube 105. The outer wall of the conical tube 105 is sleeved with a horizontal tube 102. A rubber ring 106 is fixedly connected inside the horizontal tube 102. The rubber ring 106 is made of natural rubber. A hoop 101 is sleeved on the protruding parts of the outer walls of the horizontal tube 102 and the conical tube 105. Square blocks 103 are fixedly connected to both ends of the hoop 101. Both square blocks 103 are threadedly connected to bolts 104.

[0026] Working principle:

[0027] Improved tangential flow ultrafiltration tube connection and limiting work:

[0028] When it is necessary to use an ultrafilter to ultrafilter water, the two horizontal tubes 102 are respectively sleeved on the outer wall of the conical tube 105. Rubber rings 106 are fixedly connected to the inner walls of the two horizontal tubes 102 to prevent water leakage during water source transportation. Subsequently, the hoop 101 is sleeved on the protruding parts of the outer walls of the horizontal tube 102 and the conical tube 105. Align the square blocks 103 fixed at both ends of the hoop 101, and then rotate the bolt 104 downward to fix the two square blocks 103, thereby fixing the horizontal tube 102 and the conical tube 105 through the hoop 101, making the horizontal tube 102 and the conical tube 105 fit tightly. In this way, the tightness of the connection between the horizontal tube 102 and the conical tube 105 can be improved.

[0029] Improved tangential flow ultrafiltration tube fixing and water ultrafiltration work:

[0030] After assembling and limiting the ultrafiltration tube 6, the conical tube 105 and the horizontal tube 102, place the ultrafiltration tube 6 in the first housing 3 and the second housing 4. Subsequently, align the four sides of the first housing 3 and the second housing 4, and insert the straight rod 201 and the second clamping block 203 through the openings processed in the middle of the square plate 204 and the concave plate 205 (as Figures 6-7 ). When the straight rod 201 drives the first clamping block 202 to abut against the outer wall of the square plate 204, rotate the straight rod 201 to drive the first clamping block 202 to rotate synchronously. Since the surface of the concave plate 205 is processed with protruding parts, when the first clamping block 202 rotates, the square plate 204 and the concave plate 205 will relatively gather, thereby driving the first housing 3 and the second housing 4 to relatively gather through the square plate 204 and the concave plate 205. At this time, the rubber pad 5 between the first housing 3 and the second housing 4 will be deformed by force. The rubber pad 5 has a waterproof function to prevent water leakage. Subsequently, fix the other side of the first housing 3 and the second housing 4 in the same movement mode as above. In this way, it can be fixed to the ultrafiltration tube 6 through the internal support. Then connect the two horizontal tubes 102 to the external conduit, and perform ultrafiltration work on water through the ultrafiltration tube 6. The ultrafiltered water is discharged from the lower horizontal tube 102. In this way, ultrafiltration work on water can be carried out.

[0031] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details may be made within the scope of the claims.
