Description

Technical Field

[0001] The utility model relates to the technical field of sampling and preparing samples for testing, in particular to a pressure filtration liquid sampling device. Background Art

[0002] Liquid sampling is an indispensable operation in engineering, experiment and production activities. Its accuracy and reliability are of great significance to the analysis and determination of substances.

[0003] Generally speaking, before taking the liquid, the corresponding sampling method and container should be selected according to the operation needs. Then, in a clean operating environment and without external interference and pollution, an appropriate sampling location should be selected to ensure the quality of sampling. Finally, the sampler should enter the sampled liquid and take the sample, and the sampling speed should be slightly slowed down to avoid precipitation and impurities entering the sample.

[0004] For ordinary solutions, there are fewer interference factors in liquid collection. Generally, as long as the solution is mixed evenly, the solution obtained meets the requirements and the final result is reliable. However, in many cases, the liquid needs to be added with reagents or filtered as needed, and can only be sampled after mixing evenly. In particular, when collecting the clarified liquid or supernatant of a partial mixed solution, the sampling carrier may enter the container of the mixed solution at too fast a speed or other factors, causing the solution to fail to stratify and remix together, thereby affecting the effect of liquid collection and ultimately affecting the achievement of the desired goals of engineering, experimental and production activities.

[0005] In the prior art, it is of course possible to regain clarified liquid or supernatant by controlling the falling speed of the liquid extractor or the resting time of the liquid extractor after it falls to the calibrated position. However, such operation has poor controllability, and different environments will make it impossible to determine the exact waiting time, which is obviously unreasonable for controlling the overall rhythm of engineering, experiments and production activities.

[0023] The utility model relates to a filter press liquid extraction device, comprising a liquid extraction channel 1, a detachable filter press assembly 2 is provided at the lower end of the liquid extraction channel 1, and a lifting mechanism is provided for the liquid extraction channel 1; the liquid extraction channel 1 is spatially connected to the detachable filter press assembly 2.

[0024] In the present invention, the pressure filtration liquid collection device is actually an auxiliary liquid collection tool, with the liquid collection channel 1 to meet the liquid collection probe and other liquid collection devices to enter and obtain the upper layer of liquid processed by the detachable filter press assembly 2; in actual application, the device is moved downward as a whole through the lifting mechanism, and cooperates with the detachable filter press assembly 2 for pressure filtration. The supernatant of the mixed solution is obtained by the liquid collection device in the area where the detachable filter press assembly 2 is spatially connected to the liquid collection channel 1. After completion, the lifting mechanism rises a certain stroke. When it is still within the container range of the mixed solution, a flushing operation can be performed. After the operation is completed, the lifting mechanism rises and the container exits.

[0025] The present invention is particularly suitable for integration into the liquid extraction module of the entire machine. The lifting and lowering control of the lifting mechanism is realized through a controller, which is easily understood by those skilled in the art. Those skilled in the art can set the controller based on demand to obtain different actions of the lifting mechanism at different working rhythms.

[0026] The liquid extraction channel 1 includes an open channel 11 , and a mounting groove 12 is provided at the bottom of the open channel 11 facing upwards. The detachable filter press assembly 2 is fitted in the mounting groove 12 .

[0027] The open channel 11 includes a semi-cylindrical tube, and a semi-cylindrical groove 13 is provided in conjunction with the semi-cylindrical tube. The semi-cylindrical groove 13 is spatially connected to the detachable filter press assembly 2 .

[0028] In the present invention, in order to facilitate the flexible setting of the liquid collector and the device, the liquid collection channel 1 is set as an open channel 11, that is, the liquid collector can enter from the top to the bottom after reaching the top of the semi-cylindrical groove 13 to collect liquid, or it can reach the position of the semi-cylindrical groove 13 from the side and collect liquid from the middle downward, which is more convenient for application; generally speaking, the semi-cylindrical groove 13 and the semi-cylindrical tube are half of the cylindrical tube, and it is obvious that the semi-cylindrical groove 13 is spatially connected to the detachable filter press assembly 2.

[0029] In the present invention, the detachable filter press assembly 2 is connected to the mounting groove 12 of the liquid collection channel 1 through fasteners. In actual application, this structure satisfies the requirement that the supernatant with different components can be extracted by only replacing the detachable filter press assembly 2 without changing the liquid collection channel 1.

[0030] The detachable filter press assembly 2 includes a mounting insert that is detachably mounted in the mounting groove 12 , and a filter membrane or filter screen 21 is provided at the bottom of the mounting insert.

[0031] The installation insert includes an installation tube 22 and a reinforcement tube 23 . The upper portion of the installation tube 22 is disposed in the installation groove 12 , and the reinforcement tube 23 is disposed at the bottom of the open channel 11 outside the installation tube 22 . The filter membrane or filter screen 21 is disposed at the bottom of the reinforcement tube 23 .

[0032] An annular groove 24 is provided on the side of the mounting tube 22 corresponding to the bottom of the open channel 11, and the reinforcing tube 23 includes an annular side wall 25, and a first annular piece 26 is provided at the inner top of the annular side wall 25, and a second annular piece 27 is provided at the inner lower part of the annular side wall 25. The first annular piece 26 is provided in the annular groove 24, and the second annular piece 27 is against the bottom of the mounting tube 22.

[0033] In the present invention, the upper part of the mounting tube is matched with the mounting groove 12. Specifically, the mounting tube is set to a structure in which the outer surface of the mounting tube 22 is connected to the reinforcing tube 23. The top of the mounting tube 22 is higher than the reinforcing tube 23, so that the mounting tube 22 is connected to the mounting groove 12. At the same time, the reinforcing tube 23 is respectively connected to the annular groove 24 outside the mounting tube 22 and the bottom of the mounting tube 22 through the first annular piece 26 and the second annular piece 27. While strengthening the mounting tube 22, the pipeline in the detachable filter press assembly 2 can be further divided into several step-like structures, which effectively decomposes the pressure generated by the filter press on the filter membrane or filter screen 21, thereby preventing splashing and protecting the integrity of the filter membrane or filter screen 21 at the bottom, meeting the needs of completing multiple liquid extractions in one detection.

[0034] In actual application, the filter membrane or filter screen 21 can be matched with the bottom of the installation tube by feasible methods such as bonding or setting an installation slot for interference fit; technical personnel in this field can configure filter membranes or filter screens 21 of different specifications according to needs.

[0037] In the present invention, considering that the device needs to be cleaned after a single liquid collection is completed after the integrated detection equipment, for the convenience of layout, the lifting mechanism is no longer equipped with a horizontal moving component, so a splash-proof component 3 is set at the open channel 11. It is sufficient to complete the flushing operation in the previous container. At the same time, the splash-proof component 3 is used to prevent liquid from splashing and affecting the operation of the entire machine.

[0038] In the present utility model, during actual application, the splash-proof component 3 is set as a semi-cylindrical part, which cooperates with the semi-cylindrical tube and semi-cylindrical groove 13 of the open channel 11, with the protrusion 31 being set at the notch position of the semi-cylindrical groove 13, and the splash-proof component 3 is fastened to the outside of the semi-cylindrical part.

A synchronous belt 44 is provided outside the driving wheel 42 and the driven wheel 43, and a connecting piece 45 connected to the liquid collection channel 1 is fixedly connected to the synchronous belt 44.

[0040] In the present invention, the structure of the lifting mechanism is easily understood by those skilled in the art, that is, the controller controls the output of the motor 41, and the driving wheel 42 rotates in coordination with the driven wheel 43 through the synchronous belt 44, and then the synchronous belt 44 drives the connecting member 45 thereon, so that the liquid collection channel 1 moves up and down; generally speaking, the connecting member 45 is arranged at the top of the liquid collection channel 1 and avoids the area of ​​the semi-cylindrical groove 13. The connecting member is generally an L-shaped member, and a rib 46 is provided at a right angle position to ensure overall strength.
