Description

Technical Field

[0001] The utility model relates to the field of medicine liquid adding equipment, in particular to a constant temperature device applied to medicine liquid automatic adding equipment. Background Art

[0002] At present, our traditional on-site automatic adding equipment has no temperature control over the potions stored in the adding equipment, and basically stores them in a room temperature environment. As the global warming and the temperature rise, the room temperature can sometimes reach more than 40 degrees. Because some potions are highly volatile, such as; activators and formaldehyde used in copper immersion wires; catalysts used in nickel cylinders for gold immersion wires, ammonia and hydrochloric acid used in etching lines, etc., the potions that need to be automatically added on-site during the production process will evaporate faster as the temperature rises, and the effective potion components dissolved in the potion will evaporate faster, causing the potion to fail. The production process will be abnormal due to the imbalance of the added potion, resulting in poor product quality. Utility Model Content

[0018] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] Please refer to Figure 1-3 As shown, the thermostatic device applied to the automatic medicine adding device comprises a water pipe 2 wound around the outer periphery of the medicine tank body 1, one end of the water pipe 2 is connected to one end of the water tank 3, and the other end of the water pipe 2 is connected to the other end of the water tank 3 to form a closed loop, and a circulation pump 4 is provided at one end of the water tank 3;

[0020] The upper end surface of the water tank 3 is provided with three cooling semiconductors 5 and two heating semiconductors 6, through which the cooling semiconductors 5 and the heating semiconductors 6 conduct heat to control the water temperature in the water tank 3, and then control the temperature of the medicine tank body 1;

[0021] A temperature sensor 7 is provided at one end of the water tank 3 .

[0022] This application uses a temperature sensor to continuously collect the temperature of the water circulation, and then uses a heating semiconductor or a cooling semiconductor to conduct heat to the water circulation through the water tank to achieve a constant temperature within the preset temperature value. Finally, the water pipe can indirectly control the temperature of the medicine tank, which can keep the medicine in the addition tank in the required constant temperature environment, ensuring the stability of the medicine, and playing a very good role in the stability control of the quality of the production product.

[0023] In this embodiment, a circuit control board 8 is also included. The circuit control board 8 is electrically connected to the temperature sensor 7 for detecting the current water temperature. The two output ends of the circuit control board 8 are respectively connected to a refrigeration relay 9 and a heating relay 10. One end of the conduction end of the refrigeration relay 9 receives a voltage, and the other end is connected to the refrigeration semiconductors 5 connected in series. One end of the conduction end of the heating relay 10 receives a voltage, and the other end is connected to the heating semiconductors 6 connected in series.

[0024] After the temperature sensor collects the temperature signal, it sends a signal to the circuit control board. When the temperature is lower than the preset value, the circuit control board sends a signal to the heating relay to make the conduction end of the heating relay conductive, and +24V is supplied to the heating semiconductor through the heating relay, thereby turning on the heating. The heating semiconductor conducts heat through the water tank to the water circulation, thereby controlling the temperature rise of the water circulation in the water pipe; similarly, when the temperature is higher than the preset value, the temperature is lowered. Since the working power of the cooling semiconductor is low, three pieces are required to improve the cooling efficiency.

[0025] In this embodiment, a three-way valve 11 is provided at one end of the water tank 3. Both ends of the three-way valve 11 are used to transport water, and the remaining end is threadedly connected to a cover body, which is connected to the temperature sensor 7. The sealing effect is better when using the three-way valve, and the sensor is easier to install by twisting it at the thread.

[0026] In this embodiment, a heat conductive cover 12 is provided at the upper end of the water tank 3, and a cooling fan 13 is provided at the upper end of the heat conductive cover 12 to transfer the heat generated by the semiconductor to the cooling fan through the heat conductive cover for heat dissipation to prevent the semiconductor from being damaged.

[0027] In this embodiment, the heating semiconductor 6 is attached to the water tank 3 by means of thermal conductive silicone grease to improve heat transfer efficiency.

[0028] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
