Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a water quality testing mixing device. Background Technology

[0002] Water quality testing mixing equipment is a specialized instrument used for water sample pretreatment and analysis. It achieves uniform mixing of water samples and reagents through mechanical or magnetic stirring, ensuring the accuracy of test data. It is commonly used in sewage treatment, water quality monitoring, and scientific research experiments.

[0003] Existing water quality testing mixing equipment involves placing a container containing reagents and water samples on a base, then manually moving a motor up and down along the support surface to insert a stirring rod into the container. The motor is then started to drive the stirring rod to rotate, causing it to agitate the reagents and water samples inside the container, thus mixing them. The mixed water sample is then tested.

[0004] However, when the stirring rod agitates the water sample, the water sample and reagents form a vortex inside the container, causing the radial flow of the stirring rod to impact the inner wall of the container. This causes the container to shift after being impacted by the water sample, resulting in the stirring rod colliding with and damaging the inner wall of the container, thus affecting the normal mixing of the water sample. Utility Model Content

[0005] The technical problem to be solved by this utility model is that when the stirring rod agitates the water sample, the water sample and reagents will form a vortex inside the container, causing the radial flow of the stirring rod to impact the inner wall of the container. This causes the container to be displaced after being impacted by the water sample, resulting in the stirring rod colliding with and damaging the inner wall of the container, thus affecting the normal mixing of the water sample.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a water quality testing stirring device, comprising: a base, which is placed on a table for placing a container, wherein a support is provided on one side of the base; a motor, which is mounted on the support, wherein the output end of the motor is fixedly connected to a stirring rod through a coupling, wherein the motor drives the stirring rod to stir and mix the water sample and reagent inside the container; and a limiting device, which is mounted on the base, wherein the limiting device can be adjusted and moved to intercept and limit containers of different sizes.

[0007] Preferably, the limiting device includes: a base frame, which is fixedly connected to the base, wherein the inner wall of the base frame is threaded with bolts; a multi-hole rod, the surface of which is slidably connected to the inner wall of the base frame, wherein the multi-hole rod is placed inside the base frame and fixed by bolts; and a positioning plate, wherein the positioning rod is slidably mounted on the multi-hole rod by a spring rod, wherein the other end of the spring rod is fixedly connected to the multi-hole rod.

[0008] The effect achieved by the above components is as follows: By setting up a positioning device, firstly, the perforated rods on both sides of the base frame are manually moved, causing them to move in opposite directions along the inside of the base frame. This causes the two perforated rods to move multiple positioning plates. When the perforated rods move to the designated position, the inner wall of any hole on the perforated rod coincides with the inner wall of a hole on the base frame. At this point, bolts are manually screwed into the base frame and the perforated rods to fix the position of the perforated rods, completing the position adjustment of the positioning plates. Then, the spring rod is manually pulled to move the positioning plates closer to the perforated rods, while simultaneously placing the container on the base frame. The container is placed between the two positioning plates. Releasing the hands that pulled the two spring rods causes the spring rods to push the positioning plates back to their original position under the reaction force of the springs. This causes the positioning plates on both sides to move closer together, pressing and squeezing the container surface as they move closer, thus completing the interception and limiting of the container. This reduces the possibility of displacement of the container after being impacted by the radial flow of the stirring rod and the water sample, preventing the stirring rod from colliding with and damaging the inner wall of the container, thus affecting the normal mixing of the water sample and improving the stability of the container when stirring the water sample.

[0009] Preferably, one end of the bolt is fixedly connected to a screw block, wherein the surface of the screw block is provided with a plurality of protrusions.

[0010] The effect achieved by the above components is that by setting the tightening block, the contact area of ​​the bolt can be increased, and the convenience of manually turning the tightening block can be improved.

[0011] Preferably, an anti-slip pad is fixedly connected to one side of the base frame, wherein the surface of the anti-slip pad is provided with multiple anti-slip protrusions.

[0012] The effect achieved by the above components is as follows: by setting anti-slip pads, the fit and friction between the container and the base can be increased, reducing the possibility of the container sliding or shaking when placed on the base, and further improving the limiting effect on the container.

[0013] Preferably, a plurality of rubber strips are fixedly connected to the side of the positioning plate away from the perforated rod, and the plurality of rubber strips are arranged at equal intervals.

[0014] The effect achieved by the above components is that by setting rubber strips, the friction and fit between the positioning plate and the container surface can be increased, while separating the two and reducing the wear on the container surface when the positioning plate is squeezed.

[0015] Preferably, a baffle is fixedly connected to the end of the perforated rod away from the positioning plate, wherein the surface of the baffle is larger than the inner wall of the base frame.

[0016] The effect achieved by the above components is that by setting up baffles, the perforated rods can be intercepted during movement, reducing the possibility of the perforated rods detaching from the base frame.

[0017] Preferably, it further includes: a stabilizing component, the stabilizing component comprising: a screw hole block, the screw hole block being fixedly connected to the multi-hole rod, wherein the inner wall of the screw hole block is threadedly connected to a screw; and a top block, the top block being rotatably connected to the screw via a bearing, wherein the position of the top block corresponds to that of the positioning plate.

[0018] The effect achieved by the above components is as follows: By setting up a stabilizing component, when the positioning plate clamps the container, manually rotating the screw causes it to move along the inside of the screw hole block towards the positioning plate. This causes the screw to drive the top block to move towards the positioning plate. When the top block moves to the position where it is in contact with the surface of the positioning plate, the top block, together with the screw, screw hole block, and multi-hole rod, supports and limits the positioning plate, thereby achieving auxiliary reinforcement of the positioning plate, reducing the shaking of the positioning plate when clamping some large containers, and further improving the positioning effect and stability of the container.

[0019] Preferably, a round rod is fixedly connected to the side of the top block near the screw hole block, wherein the round rod is placed inside the screw hole block to limit the position of the top block.

[0020] The effect achieved by the above components is as follows: by setting the round rod, the round rod can slide inside the screw hole block and limit the top block, reducing the situation where the top block rotates when driven by the screw, thus affecting the support positioning plate of the top block.

[0021] The beneficial effects of this utility model are:

[0022] By setting a positioning device, containers of various sizes can be intercepted and limited, reducing the displacement of the container after being impacted by the radial flow of the stirring rod and the water sample, which could cause the stirring rod to collide with and damage the inner wall of the container, affecting the normal mixing of the water sample, and improving the stability of the container when stirring the water sample.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Example 1, Figures 1 to 4 The water quality testing stirring device shown includes: a base 1, which is placed on a table for placing a container, wherein a support 2 is provided on one side of the base 1; a motor 3, which is mounted on the support 2, wherein the output end of the motor 3 is fixedly connected to a stirring rod 4 through a coupling, wherein the motor 3 drives the stirring rod 4 to stir and mix the water sample and reagent inside the container; and a limiting device 5, which is mounted on the base 1, wherein the limiting device 5 can be adjusted and moved to intercept and limit containers of different sizes.

[0032] Figure 3 and Figure 4The limiting device 5 shown includes: a base frame 51, which is fixedly connected to the base 1, wherein the inner wall of the base frame 51 is threaded with bolts 52; a multi-hole rod 55, the surface of which is slidably connected to the inner wall of the base frame 51, wherein the multi-hole rod 55 is placed inside the base frame 51 and fixed by bolts 52; and a positioning plate 57, wherein the positioning rod is slidably mounted on the multi-hole rod 55 by a spring rod 56, wherein the other end of the spring in the spring rod 56 is fixedly connected to the multi-hole rod 55. By setting the positioning device, the multi-hole rods 55 on both sides of the base frame 51 are first manually moved, so that the multi-hole rods 55 on both sides move in opposite directions along the inside of the base frame 51, so that the two multi-hole rods 55 drive multiple positioning plates 57 to move. When the multi-hole rod 55 moves to the designated position, the inner wall of any hole on the multi-hole rod 55 coincides with the inner wall of a hole on the base frame 51. At this time, the bolts 52 are manually screwed into the base frame 51 and... The porous rod 55 is fixed in position inside, and the position of the positioning plate 57 is adjusted. At this time, the spring rod 56 is manually pulled to move the positioning plate 57 closer to the porous rod 55. At the same time, the container is placed on the base frame 51, so that the container is placed between the two positioning plates 57. Then, the hands that pulled the two spring rods 56 are released. Under the reaction force of the spring in the spring rod 56, the spring rod 56 pushes the positioning plate 57 to reset and move, so that the positioning plates 57 on both sides move closer to each other. When the positioning plates 57 on both sides move closer to each other, they adhere to and squeeze the surface of the container, thereby completing the interception and limitation of the container. This reduces the displacement of the container after being impacted by the radial flow of the stirring rod 4 and the water sample, which could cause the stirring rod 4 to collide with and damage the inner wall of the container, affecting the normal mixing of the water sample. This improves the stability of the container when stirring the water sample.

[0033] Figure 3 and Figure 4 One end of the bolt 52 shown is fixedly connected to a screw block 53, wherein the surface of the screw block 53 is provided with multiple protrusions. By setting the screw block 53, the contact area of ​​the bolt 52 can be increased, and the convenience of manually turning the screw block 53 can be improved. One side of the base frame 51 is fixedly connected to an anti-slip pad 54, wherein the surface of the anti-slip pad 54 is provided with multiple anti-slip protrusions. By setting the anti-slip pad 54, the fit and friction between the container and the base frame 51 can be increased, reducing the slippage or shaking of the container when it is placed on the base frame 51, and further improving the limiting effect on the container.

[0034] Figure 3 and Figure 4The positioning plate 57 shown has multiple rubber strips 58 fixedly connected to the side away from the perforated rod 55. The rubber strips 58 are arranged at equal intervals. By setting the rubber strips 58, the friction and adhesion between the positioning plate 57 and the container surface can be increased, while separating the two and reducing the wear caused to the surface of the container when the positioning plate 57 squeezes it. The end of the perforated rod 55 away from the positioning plate 57 is fixedly connected to a baffle 59. The surface of the baffle 59 is larger than the inner wall of the base frame 51. By setting the baffle 59, the perforated rod 55 can be intercepted during the movement, reducing the possibility of the perforated rod 55 detaching from the interior of the base frame 51.

[0035] Figure 4 The document also includes: a stabilizing component 6, comprising: a screw hole block 61, which is fixedly connected to a multi-hole rod 55, wherein a screw rod 62 is threadedly connected to the inner wall of the screw hole block 61; and a top block 63, which is rotatably connected to the screw rod 62 via a bearing, wherein the top block 63 corresponds to the position of the positioning plate 57. By setting the stabilizing component 6, when the positioning plate 57 clamps the container, the screw rod 62 is manually rotated, causing the screw rod 62 to move along the inside of the screw hole block 61 toward the positioning plate 57, thereby causing the screw rod 62 to drive the top block 63 to move toward the positioning plate 57. When the top block 63 moves to a position that is in contact with the surface of the positioning plate 57, the top block 63, together with the screw rod 62, the screw hole block 61, and the multi-hole rod 55, supports and limits the positioning plate 57, thereby achieving auxiliary reinforcement of the positioning plate 57, reducing the shaking of the positioning plate 57 when clamping some large containers, and further improving the positioning effect and stability of the container.

[0036] Figure 4 A round rod 64 is fixedly connected to the side of the top block 63 near the screw hole block 61. The round rod 64 is placed inside the screw hole block 61 to limit the top block 63. By setting the round rod 64, the round rod 64 can slide inside the screw hole block 61 and limit the top block 63, reducing the possibility of the top block 63 rotating when driven by the screw 62, which would affect the support of the top block 63 for the positioning plate 57.

[0037] Working principle: First, manually move the perforated rods 55 on both sides of the base frame 51, so that the perforated rods 55 on both sides move in opposite directions along the inside of the base frame 51, so that the two perforated rods 55 drive multiple positioning plates 57 to move. When the perforated rods 55 move to the designated position, the inner wall of any hole on the perforated rod 55 coincides with the inner wall of the hole on the base frame 51. At this time, manually screw the bolts 52 into the base frame 51 and the perforated rods 55 to fix the position of the perforated rods 55, and complete the position adjustment of the positioning plates 57. At this time, manually pull the spring rods 56 to move the positioning plates 57 closer to the perforated rods 55. At the same time, place the container on the base frame 51 so that the container is placed between the two positioning plates 57. At this time, release the hands that pulled the two spring rods 56. Under the reaction force of the spring in the spring rods 56, the spring rods 56 push the positioning plates 57 to reset and move, so that the positioning plates 57 on both sides move closer to each other. When the positioning plates 57 on both sides move closer to each other, they adhere to and squeeze the surface of the container, thereby completing the interception and limitation of the container.

[0038] When the positioning plate 57 clamps a large container, the screw 62 is manually rotated, causing the screw 62 to move along the inside of the screw hole block 61 towards the positioning plate 57. This causes the screw 62 to drive the top block 63 to move towards the positioning plate 57. When the top block 63 moves to a position that is in contact with the surface of the positioning plate 57, the top block 63, together with the screw 62, the screw hole block 61, and the multi-hole rod 55, supports and limits the positioning plate 57, thereby achieving auxiliary reinforcement of the positioning plate 57.

[0039] At this time, the manual motor 3 moves up and down along the surface of the support 2 and moves the stirring rod 4 to the position of being inserted into the container. Then the motor 3 is started to drive the stirring rod 4 to rotate, so that the stirring rod 4 stirs the reagent and water sample inside the container by rotating, thereby achieving the mixing of the water sample and reagent. Then the mixed water sample is tested.
