Adjustable gravity leg 5 includes that gravity leg adjusts pipe 23, gravity leg and adjusts screw thread 24, gravity leg and adjusts pipe backup pad 25, "ten" style of calligraphy recess 26, and wherein gravity leg adjusts 23 upper surfaces and is equipped with "ten" style of calligraphy recess 26, gravity leg adjusts 23 surface of pipe and adjusts screw thread 24 for the gravity leg to adjust screw thread 24 and set up on gravity leg adjusts pipe backup pad 25 through the gravity leg.
The EC-D type extraction tank is divided into a mixing chamber 6 and a clarifying chamber 7 in a single stage, water phase and organic phase materials enter the mixing chamber 6 for mixing extraction, and then the mixed phase enters the clarifying chamber 7 for clarifying and phase splitting after being regulated by an adjustable inserting plate 4 on a partition plate 11 of the mixing chamber. The water phase and the organic phase after phase separation enter the next stage for mixing and clarification through a water phase channel 8 and an organic phase channel 9 respectively after the pressure flow is adjusted by an adjustable gravity leg 5. The sight glass 10 is respectively arranged outside the single-stage clarifying chamber and the single-stage mixing chamber of the extraction tank and is used for observing the mixing and phase splitting conditions of the extraction tank.
The support frame 1 shaped like a Chinese character 'ri' is supported as a clarification chamber in the clarification chamber 7, and the number thereof can be increased or decreased as appropriate. The external reinforcing tube 2, the reinforcing angle plate 3 and the reinforcing transverse plate 12 are arranged on the periphery of the external part of the extraction tank and are of reinforcing structures, so that the overall strength of the extraction tank is ensured.
(I) 'Ri' -shaped support frame
Because the mixing and clarifying chamber is rectangular, if a height difference exists between the single stage and the single stage, the pressure difference is large, the strength of the plastic material is slightly poor, and the traditional internal support isThe shape backup pad, this kind of backup pad occupy cross sectional area great, and the middle part is panel, does not utilize the two-phase separation of mixing the clarification chamber, so changes the structure into "day" font and supports 1, and the material is changed into stainless steel.
The width and the length in the clarification chamber are measured well before the installation, use the stainless steel angle steel prefabricated according to the specification, screw hole is opened at the angle steel both ends, can assemble in inside when the installation, according to clarification chamber length adjustment carriage quantity and interval, it is convenient to be under construction, and the practicality is strong. The whole support frame is fixed on the interstage plate of the clarification chamber.
(II) external reinforcement
Because of the extraction tank basic material is the plastics material, the cell body intussuseption is filled into behind the material that peripheral panel receives pressure great, after building large-scale plastics material extraction tank, this problem is more outstanding, if not consolidate, then there is the danger of warping and revealing in the extraction tank. Therefore, do the outside reinforcement of extraction tank, transversely use and strengthen diaphragm 12 and strengthen 3 reinforcing bulk strength of scute, vertically from the groove top through strengthening the diaphragm vertically punch until the bottom plate, then penetrate the reinforced pipe 2 of same pipe diameter in the hole to strengthen the holistic intensity of extraction tank, guarantee that the extraction tank warp evenly controllable.
(III) mixed phase outlet adjustable plugboard
The mixed phase outlet in the mixing chamber of the traditional EC-D type extraction tank is generally the upper part of the mixing chamber, and the upper outlet has the defects of overlarge mixing intensity and nonadjustable mixing time in view of actual operation conditions. Therefore, the mixed phase outlet adjustable inserting plate 4 is manufactured in the partition plate of the mixing chamber, and the specific mode is that an opening is formed in the middle of the partition plate 11 of the mixing chamber, and inserting plate rails 18 are manufactured on two sides of the opening; the insert plate is also provided with openings 22. Because the opening is below the liquid level when using, can't directly perceivedly know opening switch or size condition, consequently the preparation has adjustment gear 21 in picture peg upper portion, can adjust the opening size that the gear corresponds according to the in-service use condition.
Through the adjustable picture peg of mixed phase export, can be according to the mixing time of material condition control material in the hybrid chamber, still can be according to the material condition regulation mixed phase trompil size, optimize the extraction tank operational aspect.
(IV) Adjustable gravity leg
The gravity leg has the main function of ensuring that the water phase enters the gravity leg from the lower part and enters the next stage, and avoiding the upper organic phase from entering together; meanwhile, the height of the whole liquid level of the extraction stage is controlled by the height of the gravity leg. The gravity leg of the traditional extraction tank is fixed in height and has no adjustable function, and the height is very easy to change after multiple maintenance and is difficult to maintain. Therefore, the adjustable gravity leg 5 is manufactured, the gravity leg adjusting pipe supporting plate 25 is manufactured on a channel where water phase enters the next stage, a round hole and a thread 24 are formed in the middle of the supporting plate and are matched with the thread of the gravity leg adjusting pipe, the adjusting pipe 23 can be rotated by the aid of the thread (the upper portion of the threaded pipe is provided with a cross-shaped groove 26, and the adjusting pipe is operated at the top of the groove through a corresponding screwing rod), and ascends and descends through the thread. The expansion coefficient of the plastic material is large, so that when the adjustable gravity leg is manufactured, the stainless steel material with the low expansion coefficient is used, and the use reliability of the stainless steel material is ensured.
