Description

Technical Field

[0001] This utility model relates to the field of magnetic stirrers, and more specifically, to a heat-collecting magnetic stirrer for auxiliary materials. Background Technology

[0002] The heat-collecting magnetic stirrer uses electromagnetic drive to rotate the stir bar, which can heat the solution while stirring it. It has the advantages of being noiseless, vibration-free, and heating up quickly. However, when using magnetic stirrers on the market to stir solutions in containers, most containers are placed directly on the smooth surface of the stirring base. When the surface of the stirring base is wet, it becomes slippery, which reduces the friction between the surface of the stirring base and the bottom of the container. As a result, the container will move back and forth on the surface of the stirring base, which may cause the container to tip over. Therefore, a heat-collecting magnetic stirrer was designed to address this issue.

[0003] Therefore, a heat-collecting magnetic stirrer for auxiliary materials is proposed to address the above problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a heat-collecting magnetic stirrer for auxiliary materials, so as to solve the problems mentioned in the background art.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A heat-collecting magnetic stirrer for auxiliary materials includes a base. Two mounting rods are fixedly connected to the top of the base. A rotating rod is rotatably connected to the middle of each of the two mounting rods. A connecting rod is rotatably connected to both ends of each of the two rotating rods. A sliding plate is rotatably connected between the two connecting rods. Both sliding plates are slidably connected to the two mounting rods. A spring is fixedly connected to one side of each of the two sliding plates. A clamping block is fixedly connected to the end of each spring. Both clamping blocks are arc-shaped.

[0009] Furthermore, a cylinder is fixedly connected to the top of the base, and the output end of the cylinder is fixedly connected to the middle of a sliding plate.

[0010] Furthermore, a placement platform is fixedly connected above the base, the placement platform is located in the middle of the two clamping blocks, and a stainless steel cup is placed on the placement platform.

[0011] Furthermore, a fixing rod is fixedly connected to the top of the base, a lifting block is slidably connected to the outer wall of the fixing rod, and a fastening bolt is threadedly connected to one side of the lifting block.

[0012] Furthermore, a detection rod is inserted into one side of the lifting block, and the lower end of the detection rod is located inside the stainless steel cup.

[0013] Furthermore, a display screen is mounted on one side of the base.

[0014] Furthermore, a knob is installed on one side of the base.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] In this solution, the heat-collecting magnetic stirrer for this auxiliary material does not use the traditional method of placing the container directly on the smooth stirring base. Instead, two mounting rods are provided above the base, and the two ends of the rotating rods are connected to the sliding plate through connecting rods to form a stable and adjustable clamping system. During preparation, the operator starts the cylinder to push the sliding plate to slide on the mounting rods. The distance between the two clamping blocks can be precisely adjusted according to the size of the stainless steel cup, so that the clamping blocks fit tightly against the outer wall of the cup. This solves the problem of unstable contact between the container and the stirring base, which leads to displacement, and effectively avoids the risk of the container tipping over due to positional shift during stirring.

[0027] Example

[0028] Please see Figure 1-4A type of auxiliary material heat-collecting magnetic stirrer has a base 1 made of high-strength engineering plastic in one piece, possessing good insulation and stability. Two mounting rods 19 are firmly fixed to the base 19 via welding. The two mounting rods 19 are arranged in parallel and each is rotatably connected to a rotating rod 2 at its center via a high-precision bearing. This bearing is a self-lubricating bearing, which effectively reduces rotational friction resistance and extends service life. Both ends of the two rotating rods 2 are rotatably connected to connecting rods 21 via pins. The pins are chrome-plated to enhance wear resistance and corrosion resistance. A sliding plate 22 is rotatably connected between the two connecting rods 21 via an adjustable rotating connection structure. The sliding plate 22 is provided with a rotating seat connected to the connecting rod 21. The rotating seat has a rotating hole adapted to the pin, and a friction-reducing copper sleeve is embedded in the rotating hole. Both sliding plates 22 are slidably connected to the two mounting rods 19. The sliding plate 22 is provided with a sliding groove adapted to the mounting rod 19. The inner surface of the sliding groove is polished to make the sliding process smoother. A spring 23 is fixedly connected to one side of the two sliding plates 22. The spring 23 is made of stainless steel and has high elasticity and fatigue resistance. A clamping block 24 is fixedly connected to the end of the spring 23. Both clamping blocks 24 are arc-shaped, and the inner surface of the clamping block 24 is provided with an anti-slip rubber pad to increase the friction with the clamped object.

[0029] Please see Figure 1-4 A cylinder 25 is fixedly connected to the top of the base 1 by bolts. Its output end and the middle of a sliding plate 22 are fixedly connected by a welded connecting block. The connecting block, the sliding plate 22 and the output end of the cylinder 25 are all fully welded to ensure a firm connection.

[0030] Please see Figure 1-4 A placement platform 17 is fixedly connected to the top of the base 1 by screws. The placement platform 17 is made of heat-insulating ceramic material, which can effectively reduce heat transfer to the base 1. The placement platform 17 is located in the middle of the two clamping blocks 24. A stainless steel cup 18 is placed on top of the placement platform 17. The stainless steel cup 18 is made of food-grade 304 stainless steel, which has good corrosion resistance and thermal conductivity. The stainless steel cup 18 is filled with heat-conducting oil or silicone oil as a heat conduction medium. During the stirring operation, the beaker containing the material needs to be placed inside the stainless steel cup 18. At the same time, a rotor is placed inside the beaker so that the material can be stirred by using magnetic force to drive the rotor.

[0031] Please see Figure 1-4A fixed rod 13 is welded and fixedly connected to the top of the base 1. A lifting block 14 is slidably connected to the outer wall of the fixed rod 13. The lifting block 14 is provided with a through hole that matches the fixed rod 13, and a wear-resistant bushing is provided in the through hole. A fastening bolt 15 is threadedly connected to one side of the lifting block 14. The fastening bolt 15 is made of high-strength alloy steel. By tightening or loosening the fastening bolt 15, the position of the lifting block 14 on the fixed rod 13 can be locked and adjusted.

[0032] Please see Figure 1-4 The lifting block 14 has a mounting hole on one side, and the detection rod 16 is inserted into the mounting hole by interference fit. The detection rod 16 is a temperature detection rod 16, and its lower end is located inside the stainless steel cup 18 for real-time monitoring of the temperature of the liquid inside the stainless steel cup 18.

[0033] Please see Figure 1-4 A display screen 11 is installed on one side of the base 1, which is connected to the detection rod 16 via a wire to display the temperature data detected by the detection rod 16 in real time.

[0034] Please see Figure 1-4 A knob 12 is installed on one side of the base 1. The knob 12 is used to adjust the magnetic field strength and heating temperature.

[0035] Working principle: Conduct a comprehensive inspection of the connections of all components of the equipment, paying particular attention to the connections of the mounting rod 19 and fixing rod 13 on the base 1, ensuring there are no signs of looseness. Confirm that the stainless steel cup 18 is securely placed on the heat-insulating ceramic placement platform 17, and that the stainless steel cup 18 is filled with an appropriate amount of heat-conducting oil or silicone oil.

[0036] Place the beaker containing the material into the stainless steel cup 18, and then place the rotor inside the beaker.

[0037] When the device is turned on, the piston cylinder 25 above the base 1 starts. The output end of the cylinder 25 pushes the sliding plate 22 welded to it to slide. The sliding of the sliding plate 22 drives the rotating rod 2 to rotate through the connecting rod 21, further precisely adjusting the position of the clamping blocks 24, so that the two clamping blocks 24 tightly and firmly clamp the stainless steel cup 18. The anti-slip rubber pad on the inner surface of the clamping blocks 24 increases the friction and effectively prevents the stainless steel cup 18 from shaking.

[0038] Turn knob 12 again. Knob 12 is connected to the magnetic field adjustment circuit and heating temperature control circuit inside the equipment. Turning knob 12 clockwise increases the magnetic field strength, causing the magnetic stirrer to generate a stronger magnetic force, driving the rotor inside the beaker to rotate faster and increasing the stirring speed of the material. At the same time, the heating temperature rises, and the heat-conducting oil or silicone oil in the stainless steel cup 18 heats up more quickly, more efficiently and evenly transferring heat to the beaker and the material, thus aiding in the heating of the material. Turning knob 12 counterclockwise reduces the magnetic field strength and heating temperature.

[0039] The temperature sensing rod 16 on the lifting block 14 monitors the liquid temperature inside the stainless steel cup 18 in real time. Workers adjust the height of the lifting block 14 on the fixed rod 13 by tightening or loosening the fastening bolts 15 to ensure the lower end of the sensing rod 16 is in the appropriate position for accurate temperature data acquisition.

[0040] The temperature sensor 16 transmits the detected temperature data to the LCD screen 11 on one side of the base 1. Based on the stirring effect, material reaction, and real-time temperature, the operator continuously fine-tunes the magnetic field strength and heating temperature using the knob 12 to meet experimental requirements.

[0041] After the mixing operation is completed, the equipment power is turned off, the cylinder 25 retracts, causing the sliding plate 22 to slide. The sliding plate 22, via the connecting rod 21, drives the rotating rod 2 to rotate in the opposite direction, causing the clamping block 24 to reset and releasing the clamp on the stainless steel cup 18.

[0042] Remove the beaker and rotor from stainless steel cup 18, clean and maintain the equipment, and prepare it for the next use.

[0043] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
