Description

Technical Field

[0001] This utility model relates to the field of separation equipment technology, specifically to a pressing device for a cation exchange pretreatment device. Background Technology

[0002] In the field of soil testing and analysis, the determination of cation exchange capacity is an important task. In order to accurately determine the cation exchange capacity, a series of pretreatment operations are usually required for soil samples. Among them, the cation exchange capacity pretreatment equipment is the key tool to complete this task.

[0003] During the experiment, the pressure ring on the funnel plays a crucial role. It needs to press the filter paper tightly to ensure that the soil sample can be effectively blocked on the filter paper during subsequent reagent addition operations without leakage.

[0004] However, the pressure ring often fails to press properly during use, leading to a series of adverse consequences. When adding reagents to the apparatus, the pressure ring fails to provide sufficient pressure, preventing a tight seal from forming between the filter paper and the funnel. As a result, soil can leak out through the gaps between the filter paper and the funnel and directly enter the suction flask below, affecting the experimental results, causing the loss of soil samples, and reducing work efficiency. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a clamping device for a cation exchange pretreatment equipment.

[0006] This utility model is achieved through the following technical solution:

[0007] A clamping device for a cation exchange pretreatment equipment includes a pretreatment equipment body and several outlets at its lower part. A funnel and a filtration bottle are placed sequentially at the lower part of any one outlet. A filter plate is provided in the funnel, and filter paper is provided on the filter plate. A pressure ring is sleeved inside the funnel. A side-flipping pressure ring is provided on the upper part of the pressure ring. A flipping plate is connected to one side of the pressure ring. The tail of the flipping plate is connected and fixed to a telescopic cylinder through a first bracket hinged to it. Support rods are hinged to both sides of the middle part of the flipping plate. The support rods extend downward and are hinged to support seats.

[0008] Alternatively, the telescopic cylinder can be connected and fixed to the pretreatment equipment body via a second bracket.

[0009] Alternatively, the support base can be connected and fixed to the second bracket.

[0010] Alternatively, a rubber pad may be provided on the contact surface between the pressure ring and the pressure ring.

[0011] Alternatively, the telescopic rod of the telescopic cylinder can be connected and fixed to the bottom of the first bracket.

[0012] Compared with existing technologies, the advantages of this invention are as follows: By setting a reversible pressure ring on the upper part of the pressure ring, this invention fundamentally solves a series of problems caused by the soil mixture flowing into the filtration flask during the test, thus better ensuring the experimental results, greatly preventing the loss of soil samples, and improving work efficiency.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0018] like Figure 1 , 2 As shown, a clamping device for a cation exchange pretreatment equipment includes a pretreatment equipment body 1 and several outlets 2 at its lower part. A funnel 3 and a suction flask 4 are placed sequentially at the lower part of any outlet 2. A filter plate 5 is provided in the funnel 3, and filter paper 6 is provided on the filter plate 5. A pressure ring 7 is sleeved inside the funnel 3. A side-flipping pressure ring 8 is provided on the upper part of the pressure ring 7. A flipping plate 9 is connected to one side of the pressure ring 8. The tail of the flipping plate 9 is connected to a first bracket 10 and fixed to a telescopic cylinder 11 through a hinge. Support rods 12 are hinged to both sides of the middle part of the flipping plate 9. The support rods 12 extend downward and are hinged to a support base 13.

[0019] like Figure 2 As shown, the telescopic cylinder 11 is connected and fixed to the pretreatment equipment body 1 via the second bracket 10.

[0020] like Figure 2 As shown, the support base 13 is connected and fixed to the second bracket 10.

[0021] like Figure 2 As shown, a rubber pad is provided on the contact surface between the pressure ring 8 and the pressure ring 7 to prevent the pressure ring 8 from damaging the pressure ring 7.

[0022] like Figure 2 As shown, the telescopic rod of the telescopic cylinder 11 is connected and fixed to the bottom of the first bracket 10.

[0023] The implementation principle of a clamping device for a cation exchange pretreatment equipment according to an embodiment of this application is as follows:

[0024] When measuring the cation exchange capacity of soil, first place the filter plate 5 and filter paper 6 in the funnel 3 in sequence, then place the pressure ring 7 in the funnel 3, then insert the funnel 3 into the suction filtration flask 4, then place the suction filtration flask 4 directly below the outlet 2 of the pretreatment equipment body 1, and then place the soil sample on the top of the filter paper 6, in preparation for measuring the cation exchange capacity of soil.

[0025] When determining the cation exchange capacity of soil, the pressure ring 7 needs to be tightened to prevent the soil sample from flowing into the suction flask 4. When tightening, the telescopic cylinder 11 is activated to extend the telescopic rod. When the telescopic rod extends, it will push the support 10 upward and drive the flip plate 9 to flip around the hinge point between the support rod 12 and the support seat 13. When the flip plate 9 flips, it will drive the pressure ring 8 to press down at the same time. During the pressing process, the pressure ring 7 will be tightened. At the same time, the pressure ring 7 will press the filter paper 6 tightly onto the filter plate 5 in the funnel 3.

[0026] At this time, the pretreatment equipment body 1 is started to discharge the reagent from the outlet 2 and mix with the soil sample to form a soil mixture. Since the pressure ring 7 will press the filter paper 6 tightly onto the filter plate 5 in the funnel 3, there will be no gap between the filter paper 6 and the inner wall of the funnel 3. At this time, the soil mixture cannot be discharged from the gap between the filter paper 6 and the inner wall of the funnel 3, thereby preventing the soil mixture from flowing into the suction flask 4, which would affect the experimental results. At the same time, it will prevent the loss of soil samples and greatly improve work efficiency.

[0027] When the soil cation exchange capacity is measured, the telescopic rod retracts when the telescopic cylinder 11 is activated. When the telescopic rod retracts, the pressure ring 8 will flip up, and the experimental container can be removed.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
