Description

TECHNICAL FIELD

[0001] The utility model relates to a fixture, especially a fixture for fixing the aeration membrane when processing the micro-hole on the aeration membrane. BACKGROUND

[0002] The selection of the aeration equipment not only affects the biochemical treatment effect of the sewage, but also affects the land occupation, investment and operation cost of the sewage field. The micro-hole aerator mainly includes the suspension type chain type aerator, the membrane type micro-hole aerator, the rotary cutting type aerator, the pipe type aerator, the disc type aerator, the micro-hole ceramic aerator and the hose type aerator. The gas passes through the micro-hole on the aerator and enters the sewage in the form of bubbles. After the bubbles are mixed with the sewage, the sewage can be purified. The aerator is applied in the river regulation. The gas is sent into the river through the aerator, so that the oxygen capacity in the water is improved, which is helpful for the survival of the fish and other organisms, so that the fish can effectively clean the water body. The aeration membrane is generally soft rubber or silicone and other high molecular materials. Some micro-holes need to be processed on the aeration membrane to form the aeration membrane, so that the gas enters the water body in the form of bubbles. The micro-holes on the existing aeration membrane are usually processed by the punch. The structure of the punch includes a plate body and a plurality of punch needles arranged on the plate body. When the micro-holes are processed, the aeration membrane is punched by the punch at one time, so that a plurality of micro-holes are processed on the aeration membrane. The punch is not convenient to prepare, and the uniformity of the size of the processed micro-holes cannot be well guaranteed, so that the uniformity of the gas outlet of the aerator is affected.

[0003] Chinese patent document (publication number: CN 101037266 A) discloses a manufacturing method of a polymer micro-hole aerator. The aerator with a micro-hole structure is manufactured through raw material oscillation, high-pressure setting and high-temperature sintering. The specific steps are as follows: the polymer raw material is placed in a mold and oscillated for 10-25 minutes. The raw material after oscillation is extruded and set. The setting pressure is 8-20MPA, and the setting time is 2-12 minutes. The thickness of the aerator is controlled to be 10-30MM, preferably 12-15MM. High-temperature sintering is performed at a sintering temperature of 120-210℃ for 100-200 minutes. The temperature gradient between the inner surface and the outer surface of the setting product during sintering is controlled to be 15-25℃. Cooling is performed to obtain the required product. The polymer aerator obtained by the method has low energy consumption, high mechanical strength, small and uniform bubble generation, good oxygenation effect, corrosion resistance, long service life and low blocking probability. The manufacturing process is simple and easy to master. The materials are easy to obtain, and the method has good popularization and application value.

[0004] The preparation method of the micro-porous aerator is to prepare a plurality of micro-holes on the aeration membrane by raw material oscillation, high pressure shaping and high temperature sintering, the effective micro-hole size prepared in the aeration membrane cannot be uniform, so that the bubble density generated at each position of the aeration membrane is not uniform in the actual application, which affects the water treatment effect.

The structure of the processing machine comprises a machine body 9. A needle bar 8 is vertically movably arranged on the machine body 9. A thorn needle 6 is fixed to the lower end of the needle bar 8. A working motor 10 is arranged on the machine body 9. An eccentric block 11 is fixed to the power output shaft of the working motor 10. The two ends of the pull rod 7 are movably connected with the eccentric block 11 and the needle bar 8 respectively. Under the driving of the working motor 10, the thorn needle 6 reciprocates in the vertical direction. The cross section of the working end of the thorn needle 6 is C-shaped, so that C-shaped micro-hole structures are processed on the aeration membrane 19. The transverse size of the obtained micro-hole structure is 1-2 mm. 6000-7000 micro-hole structures can be processed on a spherical cap-shaped aeration membrane.

[0020] The structure of the present clamp comprises a support seat 5. The support seat 5 has a support surface. The aeration membrane 19 has a micro-hole processing area. The micro-hole processing area on the aeration membrane 19 is supported on the support surface. As shown in the figure, the support surface and the micro-hole processing area are both spherical cap-shaped. The support seat 5 is rotatably arranged on the base 14. The support seat 5 has a pivot structure for rotatably matching with the base 14. A power mechanism is drivingly connected with the support seat 5.

The pressing clamp 4 press-welds the coupling ring on the aeration membrane 19 on the support seat 5. The processing area on the aeration membrane 19 is exposed. The support surface of the support seat 5 provides support for the working area of the aeration membrane 19.

[0022] The base 14 is movably arranged. The base 14 is drivingly connected with the driving mechanism. Under the driving of the driving mechanism, the base 14 is in a movable state.
