Description

Technical Field

[0001] This invention relates to the field of experimental equipment technology, and in particular to an experimental device that facilitates the collection of crystals. Background Technology

[0002] Crystallization is a solid-state (natural or artificial) process in which atoms or molecules are highly organized into a structure called a crystal. Crystals form in some ways by precipitation from a solution; when a hot, saturated solution is cooled, the solute precipitates out in crystal form. To better study the crystallization process, experimental equipment is needed to collect the crystals.

[0003] Chinese Patent Application No. 202020754847.X discloses a crystal collector for chemical experiments, comprising a transparent box. A hinged door is connected to the left end face of the transparent box. A liquid inlet pipe is provided on the top face of the transparent box. A slider is slidably connected to the inner side of the bottom face of the transparent box, penetrating the transparent box. A first annular clamping block is provided at the top of the slider, and the first annular clamping block is fixedly connected to the slider via a connecting rod. A second annular clamping block is provided at the top of the first annular clamping block, and the second annular clamping block is rotatably connected to the first annular clamping block via a rotating shaft. This arrangement, with the first annular clamping block, the second annular clamping block, an electric push rod, and a drying plate, combined with the rotatable connection between the first and second annular clamping blocks and the fixed connection between the electric push rod and the drying plate, enables the collection and drying of crystals generated during the experiment, facilitating subsequent experiments.

[0004] The collector is quite cumbersome to use, requiring many steps and all of which must be performed manually by laboratory personnel, increasing their workload and making it inconvenient for them to use. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an experimental device that facilitates the collection of crystals. The device uses a clamping mechanism to hold the container and a stirring mechanism to stir the solution inside the container, thereby lowering the temperature of the solution and causing crystals to precipitate. The crystals are then retrieved from the container using a retrieval mechanism. The entire process is automated, reducing the workload of laboratory personnel and making the device easier to use.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An experimental device for facilitating the collection of crystals includes a workbench with a work frame mounted on its bottom, a clamping mechanism for clamping a container, a stirring mechanism for stirring a solution in the container, and a retrieval mechanism for retrieving crystals from the container.

[0010] Furthermore, the reset part includes: a sleeve, which is mounted on the U-shaped block; a rotating shaft, which is mounted on one end of the rotating block; a spring a, which is disposed inside the sleeve and sleeved on the outside of the rotating shaft; and a fixing ring, which is mounted on both ends of the spring a, one of the fixing rings being mounted on the rotating shaft and the other fixing ring being mounted on the inside of the sleeve.

[0011] Preferably, the clamping mechanism includes: a connecting rod, which is mounted on one end of the worktable; a fixing block, which is mounted on the connecting rod; a transmission shaft, with two sets of transmission shafts mounted inside the fixing block; a gear a, which is mounted on the transmission shaft and meshes with each other; a clamping roll, which is circular and used to clamp a container, with both ends of the clamping roll wound onto the transmission shaft; and a rotary drive a, which is mounted inside the fixing block and is connected to one of the sets of transmission shafts.

[0012] Furthermore, the drive unit a includes: a fixed rod a, which is mounted on the rotating block; a rotation drive component b, which is mounted inside the transmission rod; and a rope, one end of which is mounted on the fixed rod a, and the other end of which is mounted on the output shaft of the rotation drive component b.

[0013] Preferably, the salvage mechanism includes: a sleeve rod sleeved on the outside of the transmission rod; a moving plate mounted on the bottom of the sleeve rod; a rotary drive component c, multiple sets of the rotary drive component c mounted on the moving plate; a screw rod mounted on the output end of the rotary drive component c; a stirring rod having a circular groove and a three-way groove; and a telescopic net section mounted in the circular groove and the three-way groove.

[0014] Furthermore, the telescopic net section includes: a collar, which is sleeved on the transmission rod; a fixed rod b, which is disposed on the circular groove and has a threaded hole at its top; a three-way block, which is installed on the fixed rod b and inserted into the three-way groove; an elastic connecting rope a, one end of which is connected to one of the three-way blocks and the other end of which is connected to the other three-way block; an elastic connecting rope b, one end of which is connected to the three-way block and the other end of which is connected to the collar; and a retrieval net, which is installed between the collar, the elastic connecting rope a, and the elastic connecting rope b.

[0015] Furthermore, the fixing rod b is connected to the circular groove by magnetic attraction, and the three-shaped block is connected to the three-shaped groove by magnetic attraction.

[0016] Preferably, the present invention further includes a liquid extraction and injection mechanism for extracting or injecting a solution into a container; the liquid extraction and injection mechanism includes: a tilting component for driving the fixed block to tilt the container; and a liquid extraction and injection assembly for extracting or injecting a solution into the tilted container.

[0017] Furthermore, the tilting assembly includes: a gear b, which is mounted on the connecting rod; a rotary drive d, which is mounted on the worktable; and a gear c, which is mounted on the output end of the rotary drive d, with the gear b meshing with the gear c. The liquid injection assembly includes: an injection hole, which is opened at the bottom of one of the stirring rods.

[0018] The beneficial effects of this invention are as follows:

[0019] (1) The present invention clamps the container with a clamping mechanism and stirs the solution in the container with a stirring mechanism; lowers the temperature of the solution in the container to cause crystals to precipitate out; and retrieves the crystals in the container with a retrieval mechanism. The whole process is carried out by automated equipment, which reduces the workload of laboratory personnel and makes the device easy to use.

[0020] (2) In this invention, the rotating drive component d drives the gear c to rotate, which in turn drives the connecting rod to rotate, thereby driving the fixed block to rotate so that the container is in an inclined state. The rotating drive component b rotates and pulls the fixed rod a through the rope, driving the rotating block to rotate, which in turn drives the stirring rod to rotate to an inclined state. The motion drive component drives the bottom of the stirring rod to be close to the inner wall of the inclined container, and injects the solution through the injection hole through the pipe, so that the solution flows downward along the inner wall of the inclined container, preventing the directly injected solution from overflowing the container.

[0021] (3) In this invention, the rotating drive component b rotates, loosens the rope, and under the action of the reset part, drives the stirring rod to keep it in a vertically upward state. The cylinder drives the sleeve rod to move downward, which drives the telescopic net part to move downward synchronously, drives the fixed rod b to insert into the round groove and the three-shaped block to insert into the three-shaped groove. The rotating drive component c drives the screw to rotate and leave the threaded hole. The stirring rod rotates to a horizontal state, which opens the fishing net. The motion drive component drives the opened fishing net to descend to the bottom of the container, cools the container and causes the solution in the container to crystallize and precipitate. The motion drive component drives the opened fishing net to rise, and the fishing net retrieves the crystals in the solution.

[0022] (4) The present invention drives the worktable to rotate, causing the receiving bottle held by another set of clamping mechanisms to be located directly below the retrieval mechanism. The motion drive drives the spread retrieval net to move into the receiving bottle. The rotation drive b rotates and pulls the rope, causing the stirring rod to tilt and the outside of the retrieval net to tilt downward. Under the action of gravity, the crystals fall into the receiving bottle along the retrieval net. At the same time, the stirring rod is driven to swing back and forth, causing the retrieval net to shake, which makes it easier for the crystals on the retrieval net to fall into the receiving bottle.

[0023] (5) The present invention drives the fixed block to rotate so that the container is tilted, and drives the stirring rod to extend by pneumatic drive, so that the bottom of the stirring rod moves to the bottom of the inner wall of the container, and the solution in the container can be completely extracted.

[0043] like Figure 1 As shown, this embodiment provides an experimental device for collecting crystals, including a workbench 1, a work frame 11 installed at the bottom of the workbench 1, a clamping mechanism 2, which is used to clamp a container; a stirring mechanism 3, which stirs the solution in the container; and a retrieval mechanism 4, which retrieves the crystals in the container. The work frame 11 is equipped with a heating and cooling device for heating and cooling the container. Heating can be achieved by an electric heating ring, and cooling can be achieved by ice.

[0044] In this embodiment, the container is held by the clamping mechanism 2, and the solution in the container is stirred by the stirring mechanism 3; the temperature of the solution in the container is reduced, causing crystals to precipitate out. The crystals in the container are then retrieved by the retrieval mechanism 4. The entire process is carried out by automated equipment, which reduces the workload of laboratory personnel and facilitates the use of the device.

[0045] Furthermore, such as Figure 1 and Figure 2As shown, the clamping mechanism 2 includes: a connecting rod 21, which is installed at one end of the workbench 1; a fixing block 22, which is installed on the connecting rod 21; a transmission shaft 23, with two sets of transmission shafts 23 installed inside the fixing block 22; a gear a24, which is installed on the transmission shaft 23 and meshes with each other; a clamping roll 25, which is circular and used to clamp the container, with both ends of the clamping roll 25 wound onto the transmission shaft 23; and a rotary drive a26, which is installed inside the fixing block 22 and is connected to one set of the transmission shafts 23. The rotary drive a26 preferably drives a motor. It should be noted that the clamping mechanism 2 is provided in two sets on the workbench 1, with the other set used to clamp the collection bottle to collect the precipitated crystals. The inner wall of the clamping roll 25 is provided with a rubber layer to increase the friction between the clamping roll 25 and the container.

[0046] In this embodiment, the container is placed inside the clamping roll 25, and the rotation drive a26 drives the transmission shaft 23 to rotate, causing the two ends of the clamping roll 25 to be wound onto the transmission shaft 23, thereby clamping the container.

[0047] Preferred, such as Figure 1 and Figure 3 As shown, the stirring mechanism 3 includes: a fixed frame 31, which is mounted on the working frame 11; a motion drive component 32, which is mounted on the fixed frame 31; a transmission rod 33, which is mounted on the output end of the motion drive component 32; and a stirring assembly 34, which is mounted on the bottom of the transmission rod 33.

[0048] Furthermore, such as Figure 3 and Figure 4 As shown, the stirring assembly 34 includes: a U-shaped block 341, with multiple sets of the U-shaped blocks 341 mounted on the transmission rod 33; a rotating block 342, which is rotatably disposed within the U-shaped block 341; a stirring rod 343, which is mounted on the rotating block 342; a reset part 344, which drives the stirring rod 343 to remain in a vertically upward state; and a driving part a345, which drives the rotating block 342 to rotate.

[0049] Preferred, such as Figure 3 , Figure 4 and Figure 6As shown, the reset part 344 includes: a sleeve 3441, which is mounted on the U-shaped block 341; a rotating shaft 3442, which is mounted on one end of the rotating block 342; a spring a3443, which is disposed inside the sleeve 3441 and sleeved on the outside of the rotating shaft 3442; and a fixing ring 3444, which is mounted on both ends of the spring a3443, with one fixing ring 3444 mounted on the rotating shaft 3442 and the other fixing ring 3444 mounted on the inside of the sleeve 3441.

[0050] Furthermore, such as Figure 7 As shown, the drive unit a345 includes: a fixed rod a3451, which is mounted on the rotating block 342; a rotation drive component b3452, which is mounted inside the transmission rod 33; and a rope 3453, one end of which is mounted on the fixed rod a3451, and the other end of which is mounted on the output shaft of the rotation drive component b3452.

[0051] In this embodiment, the rotary drive component d512 drives the gear c513 to rotate, which in turn drives the connecting rod 21 to rotate, thereby driving the fixed block 22 to rotate so that the container is in a vertical state and the container is heated. The motion drive component 32 drives the transmission rod 33 to rotate, thereby driving the stirring rod 343 to rotate along the axis of the transmission rod 33 to stir the solution in the container.

[0052] Preferred, such as Figures 8-10 As shown, the salvage mechanism 4 includes: a sleeve rod 41, which is sleeved on the outside of the transmission rod 33; a moving plate 42, which is installed at the bottom of the sleeve rod 41; a rotary drive component c43, with multiple sets of the rotary drive component c43 installed on the moving plate 42; a screw 44, which is installed at the output end of the rotary drive component c43; a stirring rod 343 having a circular groove 3431 and a three-way groove 3432; a telescopic net section 45, which is installed in the circular groove 3431 and the three-way groove 3432; a fixed rod b452 connected to the circular groove 3431 by magnetic attraction; a three-way block 453 connected to the three-way groove 3432 by magnetic attraction; and the sleeve rod 41 is preferably driven by a cylinder (not shown in the figure), which is mounted on the fixed frame 31, and the output end of the cylinder is connected to the sleeve rod 41 by a crossbar 411.

[0053] Furthermore, such as Figure 10As shown, the telescopic net section 45 includes: a collar 451, which is sleeved on the transmission rod 33; a fixing rod b452, which is disposed on the circular groove 3431, and the top of the fixing rod b452 has a threaded hole 4521; a three-way block 453, which is installed on the fixing rod b452 and inserted into the three-way groove 3432; and an elastic connecting rope a454, one end of which is connected to... One of the three-way blocks 453 is connected to the other three-way block 453; an elastic connecting rope b455 is connected at one end to the three-way block 453 and at the other end to the collar 451; a salvage net 456 is installed between the collar 451, the elastic connecting rope a454 and the elastic connecting rope b455, and the salvage net 456 is preferably a flexible concave net.

[0054] In this embodiment, the rotation of the rotary drive component b3452 releases the rope 3453, and under the action of the reset part 344, the stirring rod 343 is driven to remain vertically upward. The cylinder drives the sleeve rod 41 to move downward, causing the telescopic net part 45 to move downward synchronously, driving the fixed rod b452 to insert into the circular groove 3431 and the triangular block 453 to insert into the triangular groove 3432. The rotary drive component c43 drives the screw 44 to rotate and leave the threaded hole 4521. Under the action of magnetic attraction, the fixed rod b452 is installed in the circular groove 3431. The rotation of the rotary drive component b3452 pulls the fixed rod a3451 through the rope 3453, driving the rotating block 342 to rotate, causing the stirring rod 343 to rotate to a horizontal state, thereby opening the fishing net 456 (initially in a horizontal state). Figure 13 In state E (state F is the open state), the motion drive 32 drives the open retrieval net 456 to descend to the bottom of the container, cooling the container and causing the solution inside to crystallize and precipitate. The motion drive 32 then drives the open retrieval net 456 to rise, and the retrieval net 456 retrieves the crystals from the solution. It should be noted that a square container is selected for this purpose. When the filter net is unfolded, it fits perfectly against the inner wall of the square container, allowing all crystals to be collected.

[0055] In this embodiment, the workbench 1 is rotated 90 degrees, driving another set of clamping mechanisms 2 to move, causing the receiving bottle held by the other set of clamping mechanisms 2 to be located directly below the retrieval mechanism 4. The motion drive 32 drives the spread retrieval net 456 to move into the receiving bottle. The rotation drive b3452 rotates and pulls the rope 3453, driving the stirring rod 343 to be in an inclined state, driving the outer side of the retrieval net 456 to tilt downward. Under the action of gravity, the crystals fall into the receiving bottle along the retrieval net 456. At the same time, the stirring rod 343 is driven to swing back and forth, causing the retrieval net 456 to shake, making it easier for the crystals on the retrieval net 456 to fall into the receiving bottle. Example 2

[0056] like Figure 5 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0057] like Figure 5 As shown, this embodiment also includes a liquid extraction and injection mechanism 5, which is used to extract or inject a solution into the container;

[0058] Among them, such as Figure 5 As shown, the liquid injection mechanism 5 includes: a tilting component 51, which drives the fixed block 22 to tilt the container; and a liquid injection component 52, which draws or injects solution into the tilted container.

[0059] The tilting assembly 51 includes: a gear b511, which is mounted on the connecting rod 21; a rotary drive d512, which is mounted on the worktable 1, and preferably drives a motor; and a gear c513, which is mounted on the output end of the rotary drive d512, and meshes with the gear b511 and the gear c513.

[0060] The injection assembly 52 includes an injection hole 3433, which is located at the bottom of one of the stirring rods 343. The stirring rod 343 is a telescopic structure that can be extended and shortened.

[0061] Specifically, such as Figure 15 As shown, the stirring rod 343 includes: a mounting rod 3434, which is mounted on the rotating block 342; a sliding rod 3436 is provided inside the mounting rod 3434; a linear drive element f3437 is mounted on the mounting rod 3434, and the output end of the linear drive element f3437 is connected to the bottom of the sliding rod 3436; a circular groove 3431, a three-way groove 3432, and a pumping hole 3433 are formed on the sliding rod 3436; the pumping hole 3433 is connected to a pumping pump through a hose; the linear drive element f3437 can drive the stirring rod 343 to extend or retract; the linear drive element f3437 is preferably an electric telescopic rod.

[0062] In this embodiment, the rotary drive component d512 drives the gear c513 to rotate, which in turn drives the connecting rod 21 to rotate, thereby causing the fixed block 22 to rotate and tilt the container. The rotary drive component b3452 rotates, pulling the fixed rod a3451 through the rope 3453, which in turn drives the rotating block 342 to rotate, causing the stirring rod 343 to rotate to the tilted position. The motion drive component 32 drives the bottom of the stirring rod 343 (the one with the injection hole 3433) to be close to the inner wall of the tilted container. The solution is injected through the injection hole 3433 through the pipe, so that the solution flows downward along the inner wall of the tilted container, preventing the directly injected solution from overflowing the container. Figure 12 As shown;

[0063] In this embodiment, by restoring the retrieval net 456 to its original state (stirring rod 343 vertically upward), inserting the screw 44 into the threaded hole 4521, and driving the screw 44 upward via the cylinder, the telescopic net part 45 is disengaged from the stirring rod 343, causing the fixing block 22 to rotate and tilt the container; the rotation drive b3452 rotates, pulling the fixing rod a3451 via the rope 3453, driving the rotating block 342 to rotate, causing the stirring rod 343 to rotate to the tilted state, and the motion drive 32 drives the bottom of the stirring rod 343 (the one with the injection hole 3433) to approach the inner wall of the tilted container, and the stirring rod 343 is extended by pneumatic drive, driving the bottom of the stirring rod 343 to move to the bottom of the inner wall of the container, its state as follows. Figure 14 As shown, the solution in the container is extracted using a pump;

[0064] It should be noted that by driving the fixed block 22 to rotate so that the container is tilted, the stirring rod 343 is extended by pneumatic drive, and the bottom of the stirring rod 343 is driven to move to the bottom of the inner wall of the container, so that the solution in the container can be completely extracted.

[0065] Work steps:

[0066] Step 1, Clamping process: Place the container inside the clamping roll 25, rotate the drive component a26 to drive the transmission shaft 23 to rotate, causing the two ends of the clamping roll 25 to be wound onto the transmission shaft 23, thus clamping the container.

[0067] Step 2, Liquid Injection Process: The rotary drive component d512 drives the gear c513 to rotate, which in turn drives the connecting rod 21 to rotate, thereby causing the fixed block 22 to rotate and tilt the container. The rotary drive component b3452 rotates, pulling the fixed rod a3451 through the rope 3453, which drives the rotating block 342 to rotate, causing the stirring rod 343 to rotate to the tilted position. The motion drive component 32 drives the bottom of the stirring rod 343 (the one with the injection hole 3433) to be close to the inner wall of the tilted container. The solution is injected through the pipe through the injection hole 3433, so that the solution flows downward along the inner wall of the tilted container, preventing the directly injected solution from overflowing the container. The state is as follows. Figure 12 As shown;

[0068] Step 3: Stirring process: The rotary drive component d512 drives the gear c513 to rotate, which drives the connecting rod 21 to rotate, thereby driving the fixed block 22 to rotate so that the container is in a vertical position and heating the container. The motion drive component 32 drives the transmission rod 33 to rotate, which in turn drives the stirring rod 343 to rotate along the axis of the transmission rod 33 to stir the solution in the container.

[0069] Step 4: Salvage Process: Rotating drive component b3452 rotates, releasing rope 3453. Under the action of reset part 344, stirring rod 343 is driven to maintain a vertical upward state. Cylinder drives sleeve rod 41 to move downward, driving telescopic net part 45 to move downward synchronously, driving fixed rod b452 to insert into circular groove 3431 and three-way block 453 to insert into three-way groove 3432. Rotating drive component c43 drives screw 44 to rotate away from threaded hole 4521. Under the action of magnetic attraction, fixed rod b452 is installed in circular groove 3431. Rotating drive component b3452 rotates, pulling fixed rod a3451 through rope 3453, driving rotating block 342 to rotate, driving stirring rod 343 to rotate to a horizontal state, thereby opening the salvage net 456 (initial state is...). Figure 13 In the E state (the open state is the F state), the motion drive 32 drives the open retrieval net 456 to descend to the bottom of the container, cools the container, and causes the solution in the container to crystallize and precipitate. The motion drive 32 then drives the open retrieval net 456 to rise, and the retrieval net 456 retrieves the crystals from the solution.

[0070] Step 5: Discharge process: The workbench 1 rotates 90 degrees, driving another set of clamping mechanisms 2 to move, causing the receiving bottle held by the other set of clamping mechanisms 2 to be located directly below the retrieval mechanism 4. The motion drive 32 drives the spread retrieval net 456 to move into the receiving bottle. The rotation drive b3452 rotates and pulls the rope 3453, driving the stirring rod 343 to be in an inclined state, driving the outer side of the retrieval net 456 to tilt downward. Under the action of gravity, the crystals fall into the receiving bottle along the retrieval net 456. At the same time, the stirring rod 343 is driven to swing back and forth, causing the retrieval net 456 to shake, making it easier for the crystals on the retrieval net 456 to fall into the receiving bottle.

[0071] Step Six: Liquid Extraction Process: By restoring the retrieval net 456 to its original state (stirring rod 343 vertically upward), the screw 44 is inserted into the threaded hole 4521. The cylinder drives the screw 44 upward, causing the telescopic net part 45 to disengage from the stirring rod 343, and causing the fixed block 22 to rotate, thus tilting the container. The rotation drive b3452 rotates, pulling the fixed rod a3451 via the rope 3453, driving the rotating block 342 to rotate, causing the stirring rod 343 to rotate to the tilted state. The motion drive 32 drives the bottom of the stirring rod 343 (the one with the extraction hole 3433) close to the inner wall of the tilted container. The stirring rod 343 is extended by pneumatic drive, causing the bottom of the stirring rod 343 to move to the bottom of the inner wall of the container, as shown in the image. Figure 14 As shown, the solution in the container is extracted using a pump.
