Description
Technical Field
[0001] The present application relates to the technical field of reaction tank weighing equipment, and in particular to a reaction tank weighing temperature control module and a reaction tank. Background Art
[0002] There are many devices in the existing fine chemical and pharmaceutical production processes that require weighing materials. Compared with volume measurement, liquid level measurement and flow measurement, weight weighing has the advantages of more intuitive results, no restrictions on material density, and no restrictions on high and low material flow rates. In order to ensure weighing accuracy, weighing components need to be calibrated.
[0003] At present, the existing weighing of the reaction tank is performed before or after the reaction tank starts working. The reaction tank cannot be weighed in real time during the reaction process, so the change of the weight of the reactants in the reaction tank cannot be observed in real time; at the same time, the reaction tank cannot be heated during weighing. Utility Model Content
[0004] In order to improve the problem that it is inconvenient to weigh and heat the existing reaction tank at the same time, the present application provides a reaction tank weighing temperature control module.
[0005] On the one hand, the present application provides a reaction tank weighing temperature control module, which adopts the following technical solution:

[0007] By adopting the above technical solution, the heating component heats the reaction tank so that the temperature inside the reaction tank reaches the predetermined reaction temperature, which is convenient for adjusting the temperature inside the reaction tank; the weight of the reaction tank is measured in real time by the weighing sensor, which is convenient for calculating the weight of the reaction tank when adding or extracting the sample solution, which is beneficial for quantitative addition or extraction of the solution.
[0008] Optionally, the elastic component includes a stop bolt, and the base is provided with a through hole for the stop bolt to pass through, one end of the head of the stop bolt is slidably inserted into the through hole, and the other end is connected to the heat conductive block, and the head of the stop bolt abuts against a side of the base away from the heat conductive block; an elastic member is arranged between the heat conductive block and the base, the elastic member is sleeved on the stop bolt, one end of the elastic member abuts against the base, and the other end abuts against the heat conductive block.
[0009] By adopting the above technical solution, the heat conductive block floats above the base under the action of the elastic component; when the heat conductive block is affected by gravity, it moves downward, thereby driving the stop bolt to slide in the through hole, limiting the moving direction of the heat conductive block, so that the heat conductive block will not be offset, which is conducive to more accurate weighing.
[0010] Optionally, a plurality of limiting rods are fixedly connected to the base, the limiting rods are placed below the heat conducting block, and a gap is provided between the top end of the limiting rods and the heat conducting block.
[0011] By adopting the above technical solution, the heat conductive block moves downward under the action of the gravity of the reaction tank. Since a limit rod is provided on the base, the stroke of the heat conductive block is limited. The symmetrical sensor plays a protective role to prevent the reaction tank from being too heavy and causing damage to the symmetrical load sensor.
[0012] Optionally, a liquid collecting tank is provided on the base between the placement slots, and a liquid outlet is provided at the bottom of the liquid collecting tank.
[0013] By adopting the above technical solution, when overflow occurs in the reaction tank, the overflow solution flows into the liquid collecting tank, and flows out from the liquid outlet for unified collection and recovery, so that the solution will not flow into the weighing sensor, thereby ensuring the normal operation of the weighing sensor.
[0014] Optionally, the heat conducting block has a fan-shaped structure, and an overflow groove is provided on a straight side of the heat conducting block.
[0015] By adopting the above technical solution, the heat conductive block has a fan-shaped structure, and multiple heat conductive blocks form a circular structure for supporting the reaction tank; when the reaction tank overflows, the solution flows into the collecting tank along the overflow groove, which facilitates the collection of the overflow solution.
[0016] Optionally, a baffle is provided at the outer arc edge of the heat conductive block, and the inner side of the baffle abuts against the side wall of the bottom end of the reaction tank.

[0018] Optionally, a plurality of mounting seats are provided at the bottom of the base, and a support member is connected to the mounting seat. The support member includes a support rod threadedly connected to the mounting seat, and a shock-absorbing pad is connected to one end of the support rod away from the base.
[0019] By adopting the above technical solution, the stability of the base is ensured by setting the support member; the support rod is threadedly connected to the mounting seat, and the height of the support member is adjusted by rotating the support rod to keep the base level. At the same time, by setting the shock-absorbing pad, the transmission of vibration is reduced, and the influence of vibration on the weighing sensor is reduced, so that the weighing is more accurate.
[0020] On the other hand, the present application provides a reaction tank, which adopts the following technical solution:
[0021] A reaction tank comprises a tank body, wherein a reaction tank weighing and temperature control module as described in any one of the above is arranged below the tank body.
[0022] By adopting the above technical solution, the setting of the above weighing temperature control module makes it easy to adjust the temperature in the reaction tank, and at the same time can measure the weight of the reaction tank in real time, so as to calculate the weight when adding or extracting the solution.

[0024] By adopting the above technical solution, the driving member drives the magnetic rotating member to rotate, and under the action of magnetic force, the magnetic rotating member drives the stirring rotor to rotate, thereby achieving stirring of the solution in the reaction tank; the stirring rotor and the magnetic rotating member are in indirect contact under the action of magnetic force, reducing the impact of the external environment on the reaction tank.
[0025] Optionally, a grid assembly is provided in the tank body, and the grid assembly includes a first grid plate, a second grid plate and an inner ring, and the first grid plate and the second grid plate are respectively fixedly connected to the two ends of the inner ring; the second grid plate is connected to an inner sleeve on the side away from the inner ring, and the inner sleeve cover is arranged on the stirring rotor and fixedly connected to the bottom of the tank body, and the side wall of the inner sleeve is provided with a plurality of gaps for the solution to flow.
[0026] By adopting the above technical solution, since the grid assembly is arranged in the tank body, it is difficult for eddy current to be generated in the reaction tank during stirring, thereby ensuring that the solution in the reaction tank is stirred evenly.
[0027] In summary, the present application includes at least one of the following beneficial technical effects:
