Description

Technical Field

[0001] This utility model relates to the field of industrial testing technology, and in particular to a device for preparing a particle suspension with constant head and constant concentration. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] In the field of scientific research and industrial testing related to particulate suspensions, the precise preparation and stable maintenance of suspensions at specific concentrations are crucial for obtaining reliable experimental results. However, existing technologies have significant shortcomings in meeting this requirement.

[0004] Currently, traditional equipment primarily uses mechanical stirring to prevent particle sedimentation, thereby controlling the suspension concentration. However, mechanical stirring only meets the single requirement of controlling suspension concentration during the experiment. In actual experimental scenarios, many experiments have strict specific requirements for head height, and existing suspension preparation equipment, after initial successful configuration, does not have the function of maintaining a stable head height. This makes it difficult to keep the head height of the suspension constant during the experiment, thus affecting the accuracy and reliability of the experimental results. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a device for preparing particle suspensions with constant head and constant concentration, thereby simultaneously meeting the requirements for preparing particle suspensions with constant head and constant concentration.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a device for preparing a particle suspension with constant head and constant concentration, comprising:

[0007] A stirring tank, the top of which is open, is used to store the prepared particulate suspension;

[0008] An electric mixer is used to be inserted into a mixing tank to stir and mix the liquid inside the tank.

[0009] A constant head assembly includes an adjusting bracket and an overflow tank that can be fixed to different height positions on the adjusting bracket. The overflow tank is provided with an inlet pipe and an overflow pipe. The overflow pipe is higher than the inlet pipe, and the distance between the overflow pipe and the inlet pipe is no more than five centimeters.

[0010] A peristaltic pump is used to draw particulate suspension from the mixing tank and transport it to the inlet pipe of the overflow tank.

[0011] Furthermore, the electric mixer includes a mixer support, a mixer capable of moving up and down along the mixer support and being inserted into the mixing tank, and a locking component for locking the mixer after the mixer height is adjusted.

[0012] Furthermore, the adjustment bracket includes a base and two side plates symmetrically arranged on the top of the base;

[0013] The overflow tank includes a tank body located between two side panels and multiple snap-fit ​​components disposed at the bottom of the tank body. Each snap-fit ​​component includes an outer sleeve fixedly disposed at the bottom of the tank body. An inner rod that can move towards or away from the adjacent side panel is movably disposed inside the outer sleeve. A compression spring is disposed between the outer sleeve and the inner rod. When the compression spring is in its natural state, the inner rod is inserted into the adjacent side panel. The side panel is provided with multiple insertion holes arranged vertically for the inner rod to be inserted. When the inner rod is outside the insertion holes, the compression spring is in a compressed state.

[0014] The overflow tank also includes a drive component for moving each inner rod away from the side plate.

[0015] Furthermore, the housing includes a water tank with an open top, and the water inlet pipe and overflow pipe are both connected to the water tank. A tray is provided at the bottom of the water tank, which is fitted with the water tank and closed at the bottom. An adjusting screw is rotatably connected to the bottom of the water tank, passing through the tray and threaded to the tray. The adjusting screw is used to push the water tank to move closer to or away from the tray.

[0016] Furthermore, the driving component includes a handle located at the top of the water tank and a movable plate located at the bottom of the handle. The handle is provided with two guide rods that limit the vertical movement distance of the movable plate. Each guide rod includes a rod body fixedly mounted on the handle and passing through the movable plate, and an end plate located at the bottom of the rod body. The outer diameter of the end plate is larger than the outer diameter of the rod body. Pull ropes are provided between the movable plate and each inner rod. When the movable plate moves towards the side closer to the handle, the pull ropes pull the corresponding inner rod to retract into the outer sleeve.

[0017] The beneficial effects of this utility model are reflected in:

[0018] This invention involves placing the raw materials to be prepared into a mixing tank and stirring them evenly with an electric stirrer until the concentration at each location is consistent and meets the experimental requirements. Then, a peristaltic pump draws the suspension from the mixing tank into an overflow tank. When the liquid level in the overflow tank is higher than the overflow pipe, the suspension will be discharged through the overflow pipe and flow to the experimental equipment. By adjusting the height of the overflow tank on the adjusting bracket, the head height between the overflow pipe and the experimental equipment can be changed, thus achieving the purpose of preparing both a suspension of a certain concentration and a suspension of a certain head.

Detailed Implementation

[0024] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-3 This utility model discloses a device for preparing a constant head and constant concentration particulate suspension, comprising:

[0026] Stirring tank 1, with an open top, is used to store the prepared particulate suspension;

[0027] Electric stirrer 2 is inserted into mixing tank 1 to drive the liquid inside mixing tank 1 to stir and mix.

[0028] The constant head assembly includes an adjusting bracket 3 and an overflow tank 4 that can be fixed to different height positions on the adjusting bracket 3. The overflow tank 4 is provided with an inlet pipe and an overflow pipe. The height of the overflow pipe is higher than the height of the inlet pipe, and the distance between the overflow pipe and the inlet pipe is no more than five centimeters.

[0029] The peristaltic pump 5 is used to extract the particulate suspension in the mixing tank 1 and transport it to the inlet pipe of the overflow tank 4.

[0030] This invention involves placing the raw materials to be prepared into a mixing tank 1 and stirring them evenly with an electric stirrer 2 until the concentration at each location is consistent and meets the experimental requirements. Then, a peristaltic pump 5 draws the suspension from the mixing tank 1 into an overflow tank 4. When the liquid level in the overflow tank 4 is higher than the overflow pipe, the suspension will be discharged through the overflow pipe and flow to the experimental equipment. By adjusting the height of the overflow tank 4 on the adjusting bracket 3, the head height between the overflow pipe and the experimental equipment can be changed, thus achieving the purpose of preparing both a suspension of a certain concentration and a suspension of a certain head.

[0031] It should be noted that, since the distance between the overflow pipe and the inlet pipe is no more than five centimeters, the water entering the overflow tank 4 through the inlet pipe can drive the water body to flow, thus avoiding the sedimentation problem of the suspended liquid in the overflow tank 4.

[0032] In one embodiment, the electric mixer 2 includes a mixer support, a mixer that can move up and down along the mixer support and be inserted into the mixing tank 1, and a locking component for locking the mixer after the mixer height is adjusted.

[0033] This design allows the mixer to be adjusted in height to meet different mixing needs and subsequent maintenance requirements.

[0034] It should be noted that the electric mixer 2 and the peristaltic pump 5 are common knowledge in this field, so their specific structural composition and working principle will not be described in detail in this article.

[0035] In one embodiment, the adjustment bracket 3 includes a base 31 and two side plates 32 symmetrically arranged on the top of the base 31;

[0036] The overflow tank 4 includes a tank body 41 located between two side plates 32 and multiple snap-fit ​​components 42 disposed at the bottom of the tank body 41. Each snap-fit ​​component 42 includes an outer sleeve 421 fixedly disposed at the bottom of the tank body 41. An inner rod 422 that can move toward or away from the adjacent side plate 32 is movably disposed inside the outer sleeve 421. A compression spring 423 is disposed between the outer sleeve 421 and the inner rod 422. When the compression spring 423 is in its natural state, the inner rod 422 is inserted into the adjacent side plate 32. The side plate 32 is provided with multiple insertion holes arranged vertically for the inner rod 422 to be inserted. When the inner rod 422 is outside the insertion hole, the compression spring 423 is in a compressed state.

[0037] The overflow tank 4 also includes a drive component 43 for driving each inner rod 422 to move away from the side plate 32.

[0038] With this design, when the height of the overflow tank 4 needs to be adjusted, simply push out the inner rod 422 located in the original socket, move the overflow tank 4 to the required height, and then push the inner rod 422 back into the socket under the push of the compression spring 423.

[0039] In one embodiment, the housing 41 includes a water tank 411 with an open top, an inlet pipe and an overflow pipe connected to the water tank 411, and a tray 412 that is fitted onto the water tank 411 and closed at the bottom. An adjusting screw 413 that passes through the tray 412 and is threaded onto the tray 412 is rotatably connected to the bottom of the water tank 411. The adjusting screw 413 is used to push the water tank 411 to move towards or away from the tray 412.

[0040] This design allows the height of the tank 41 to be adjusted after the height of the inner rod 422 is adjusted, and the water tank 411 can be moved closer to or further away from the tray 412 by rotating the adjusting screw 413, so as to fine-tune the height of the water tank 411 and meet more precise adjustment needs.

[0041] In one embodiment, the drive component 43 includes a handle 431 disposed on the top of the water tank 411 and a movable plate 432 located at the bottom of the handle 431. The handle 431 is provided with two guide rods 433 that limit the vertical movement distance of the movable plate 432. The guide rod 433 includes a rod body fixedly disposed on the handle 431 and passing through the movable plate 432 and an end plate located at the bottom end of the rod body. The outer diameter of the end plate is larger than the outer diameter of the rod body. A pull rope 434 is provided between the movable plate 432 and each inner rod 422. When the movable plate 432 moves towards the side closer to the handle 431, the pull rope 434 pulls the corresponding inner rod 422 to retract into the outer sleeve 421.

[0042] This design allows operators to adjust the height of the housing 41 by simply holding the handle 431 and simultaneously applying pressure to push the movable plate 432 towards the side closer to the handle 431. This causes the inner rod 422 to retract into the outer sleeve 421 under the pull of the pull rope 434, disengaging from the insertion hole. Then, the housing 41 can be lifted or lowered to the set height. After that, releasing the movable plate 432 allows multiple inner rods 422 to simultaneously reset under the push of the compression spring 423 and insert into the insertion hole, achieving the purpose of quick disassembly and adjustment.

[0043] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0044] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0045] Additionally, "multiple" refers to two or more.
