Description

Technical Field

[0001] This utility model relates to the field of water-reducing agent production technology, and in particular to a water-reducing agent sampling device. Background Technology

[0002] Water-reducing agents are concrete admixtures that can reduce the amount of water used in mixing. During the production process of water-reducing agents, they are generally tested. This testing usually requires the use of sampling devices to collect samples and move them to testing equipment for analysis, in order to ensure the production quality of the water-reducing agents.

[0003] Existing Chinese patents, such as CN 219391420 U, disclose a sampler for detecting water-reducing agent concentration. This sampler can pre-set the sample dosage to be extracted through a set component, and then complete the sampling of the corresponding dosage, making the entire sampling process more convenient and faster. However, after sampling, the lifting screw of the aforementioned sampler lacks a limiting structure. Therefore, during liquid transfer, the lifting screw is easily rotated by force, causing the lifting screw to drive the sliding block to move and squeeze the water-reducing agent sample in the collection box. This results in the sample easily overflowing from the collection box, causing a reduction in the sample dosage, which is detrimental to the sampling and detection of water-reducing agents. Utility Model Content

[0004] This invention proposes a water-reducing agent sampling device to solve the problem that samples easily overflow from the collection box in existing sampling devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water-reducing agent sampling device, comprising a sampling cylinder with a sample storage chamber inside, the bottom end of the sampling cylinder having an opening for sampling, the top end having a vent hole, and the sampling cylinder being provided with a sampling element for drawing the water-reducing agent sample into the sampling cylinder through the opening, and the sampling element being connected to a measuring element for measuring the dosage of the water-reducing agent sample.

[0006] The sampling cylinder is also provided with a limiting structure for clamping and fixing the measuring component. The limiting structure includes two limiting frames installed on the top of the sampling cylinder. Each of the two limiting frames is screwed with a limiting screw, and each of the two limiting frames has a slot. One end of each of the two limiting screws extends into the slot and is rotatably connected to a clamping block. Each of the two clamping blocks has a clamping groove.

[0007] Preferably, the measuring component includes a scale, the top of which extends through a vent hole to the top of the sampling cylinder, and both sides of the scale are equipped with raised strips with anti-slip layers on their surfaces. The front sides of the two limiting frames are each provided with an indicator block that cooperates with the scale, and when the clamping block is clamped to the outside of the raised strip through the clamping groove, one end of the clamping block abuts against the side wall of the scale.

[0008] Preferably, multiple anti-slip strips are installed on both sides of the inner wall of the clip groove, which are evenly distributed along the height direction.

[0009] Preferably, the sampling component includes a sampling screw screwed to the top of the sampling cylinder and a piston plate disposed in the sample storage chamber. The bottom end of the sampling screw extends into the sample storage chamber and is rotatably connected to the top end of the piston plate. The scale is mounted on the top of the piston plate.

[0010] Preferably, the sampling tube has a funnel-shaped sampling head installed at its open end.

[0011] Preferably, a handle is fixed to one side of the top of the sampling tube, and both sides of the handle have inwardly concave arc portions.

[0012] Preferably, grooves for the movement of the protrusions are provided on one side of the two limiting frames and on both sides of the inner wall of the vent hole.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] By setting a limiting structure, the scale can be clamped and fixed, thereby limiting the piston plate and keeping it stable after sampling. This prevents the sampling screw from rotating and causing the piston plate to move, which would squeeze out the sample in the sampling cylinder, resulting in a smaller sample dosage and affecting the water-reducing agent test results. This facilitates accurate sampling of the water-reducing agent and makes subsequent testing easier.

[0015] Adding anti-slip strips to the inner wall of the clamping groove can prevent slippage between the protrusion and the clamping groove, thus ensuring that the clamping block is stably clamped on the outside of the protrusion through the clamping groove, further securing the scale and keeping the sampled part fixed after sampling. This facilitates stable sampling by the sampling device and makes it easier to detect water-reducing agents. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-6 As shown, a water-reducing agent sampling device includes a sampling cylinder 1 with an internal sample storage chamber. The bottom end of the sampling cylinder 1 has an opening for sampling, and the top end has a vent hole 8. The sampling cylinder 1 is equipped with a sampling element that draws the water-reducing agent sample into the sampling cylinder 1 through the opening. The sampling element is connected to a measuring element for measuring the dosage of the water-reducing agent sample. A funnel-shaped sampling head 12 is installed at the open end of the sampling cylinder 1.

[0027] The sampling cylinder 1 is also provided with a limiting structure for clamping and fixing the measuring component. The limiting structure includes two limiting frames 4 installed on the top of the sampling cylinder 1. Each of the two limiting frames 4 is screwed with a limiting screw 7. Each of the two limiting frames 4 has a slot. One end of each of the two limiting screws 7 extends into the slot and is rotatably connected to a clamping block 9. Each of the two clamping blocks 9 has a clamping groove 11.

[0028] Specifically, the measuring component includes a scale 3, the top of which extends through the vent hole 8 to the top of the sampling cylinder 1, and both sides of the scale 3 are equipped with raised strips 6 with anti-slip layers on their surfaces. The front sides of the two limiting frames 4 are each provided with an indicator block that cooperates with the scale 3. When the clamping block 9 is clamped on the outside of the raised strip 6 through the clamping groove 11, one end of the clamping block 9 abuts against the side wall of the scale 3. Grooves for the raised strip 6 to move are provided on one side of the two limiting frames 4 and on both sides of the inner wall of the vent hole 8.

[0029] Specifically, the sampling components include a sampling screw 2 screwed to the top of the sampling cylinder 1 and a piston plate 5 disposed in the sample storage chamber. The bottom end of the sampling screw 2 extends into the sample storage chamber and is rotatably connected to the top end of the piston plate 5. A scale 3 is installed on the top of the piston plate 5.

[0030] As described above, when sampling water-reducing agents, the sampling device can be carried to the sampling location by hand with the sampling cylinder 1. Then, the sampling head 12 at the bottom of the sampling cylinder 1 is inserted into the water-reducing agent solution. Subsequently, the sampling screw 2 is rotated, so that the sampling screw 2 drives the piston plate 5 to move along the inside of the sampling cylinder 1, so as to draw the water-reducing agent from the sampling head 12 into the storage chamber inside the sampling cylinder 1, thereby completing the sampling of the water-reducing agent.

[0031] During the sampling process, the piston plate 5 will drive the scale 3 to move synchronously. At this time, the protrusion 6 will move along the groove on the limit frame 4 and the vent hole 8 under the drive of the scale 3, so as to limit the scale 3 and ensure the stable movement of the scale 3. Then the sampling personnel can watch the scale value pointed to by the indicator block to grasp the sampling dosage, which can avoid excessive or insufficient sampling dosage and is beneficial to the subsequent testing of water-reducing agent.

[0032] Simultaneously, after sampling, the sampling personnel can rotate the two limiting screws 7, causing the two limiting screws 7 to drive the clamping block 9 to move along the groove in the limiting frame 4 until the clamping block 9 is clamped on the outside of the protrusion 6 through the clamping groove 11, and one end of the clamping block 9 abuts against the side wall of the scale 3, thereby clamping and fixing the scale 3, thus limiting the piston plate 5, so that the piston plate 5 remains stable after sampling, avoiding the sampling screw 2 from rotating and driving the piston plate 5 to move, causing the sample in the sampling cylinder 1 to be squeezed out, resulting in a smaller sample dosage and affecting the water-reducing agent test results. This is conducive to the accurate sampling of water-reducing agents and facilitates the subsequent testing of water-reducing agents.

[0033] Furthermore, to facilitate the hand-holding and carrying of the sampling device, such as... Figures 1-4 As shown, a handle is fixed to one side of the top of the sampling cylinder 1, and both sides of the handle have inwardly recessed arcs.

[0034] In addition, in this embodiment, such as Figure 7As shown, multiple anti-slip strips 10 are installed on both sides of the inner wall of the clip groove 11, which are evenly distributed along its height direction. Specifically, the anti-slip strips 10 are components made of rubber material and have a certain deformation capacity when subjected to force.

[0035] When the limiting screw 7 drives the clamping block 9 to clamp and fix the protrusion 6, the protrusion 6 is inserted into the clamping groove 11. At this time, the anti-slip strip 10 is squeezed and deformed until the protrusion 6 is completely inserted into the clamping groove 11. The anti-slip strip 10 plays an anti-slip role between the protrusion 6 and the clamping groove 11, thereby ensuring that the clamping block 9 is stably clamped on the outside of the protrusion 6 through the clamping groove 11. This further achieves the clamping and fixing of the scale 3, ensuring that the sampled part remains fixed after sampling, which is conducive to the stable sampling of the sampling device and facilitates the detection of water-reducing agents.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
