[0023] Compared with the prior art, the embodiments of this utility model have the following advantages and beneficial effects:
[0024] 1. This utility model provides an explosion-proof heating device for hazardous chemical liquids. A heater is installed in a water storage tank to heat the medium fluid. The hot medium fluid is pumped through a circulation pipeline to a heat exchanger in a water bath. The heat exchanger transfers the heat of the hot water to the water in the water bath, thereby indirectly heating the hazardous chemical liquid. The water pump operates continuously to ensure that the hot water circulates between the water storage tank and the heat exchanger, maintaining a stable heating effect. This utility model avoids directly using heating equipment in a hazardous chemical environment by placing the heater outside the explosion-proof room.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0039] In the description of this utility model, it should be noted that the terms "first", "second", "third", etc. are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Example
[0040] like Figure 1 and Figure 2As shown in the figure, this utility model embodiment provides an explosion-proof heating device for hazardous chemical liquids, including a water storage tank 1, a water bath 2, and a circulation pipeline 4. The water storage tank 1 is placed outside the explosion-proof room and contains a heater. The water storage tank 1 stores the medium fluid, and the heater heats the medium fluid within it. The water storage tank 1 can be made of corrosion-resistant and high-temperature-resistant materials, such as stainless steel, to ensure long-term stable operation under high-temperature conditions. The water bath 2 is placed inside the explosion-proof room to heat the hazardous chemical liquid in a water bath. The water bath 2 contains a heat exchanger 3. The water bath 2 indirectly heats the liquid through water bath heating. The heat exchanger 3 transfers the heat from the heated medium fluid in the water storage tank 1 to the water in the water bath 2, thereby heating the liquid. The circulation pipeline 4 is connected to the water storage tank 1 and the heat exchanger 3. A water pump is installed on the circulation pipeline 4. The water pump is configured to transport the heated medium fluid in the water storage tank 1 to the heat exchanger 3 to exchange heat with the water in the water bath 2, and then send the heated medium fluid back to the water storage tank 1 for heating.
[0041] Specifically, the water storage tank 1 is connected to the heat exchanger 3 via the circulation pipe 4, and the water pump is installed on the circulation pipe 4 to form a closed circulation system. The heat exchanger 3 in the water bath 2 is connected to the circulation pipe 4 to ensure that the hot medium fluid can enter the water bath 2 and exchange heat. The heater in the water storage tank 1 heats the medium fluid. The hot medium fluid is transported to the heat exchanger 3 in the water bath 2 by the water pump through the circulation pipe 4. The heat exchanger 3 transfers the heat of the hot medium fluid to the water in the water bath 2, thereby indirectly heating the hazardous chemical liquid. After heat exchange, the temperature of the medium fluid decreases and returns to the water storage tank 1 through the circulation pipe 4 to be heated again. The water pump continues to work to ensure that the hot water circulates between the water storage tank 1 and the heat exchanger 3, maintaining a stable heating effect.
[0042] This utility model embodiment avoids the direct use of heating equipment in hazardous chemical environments by placing the heater outside the explosion-proof room. The bath heating method can heat the liquid medicine evenly. Compared with dedicated explosion-proof heating equipment, it reduces the equipment purchase and maintenance costs. The entire system achieves automated operation through the circulation pipeline 4 and water pump, which is simple to operate and easy to maintain.
[0043] It should be noted that the medium fluid here can be gas or liquid, without restriction, as long as sufficient heat exchange effect is achieved. For ease of understanding, the medium fluid will be referred to as water in the following description. The heat exchanger 3 can adopt existing structures such as aluminum flat plate radiators, without restriction; the circulation pipeline 4 is preferably made of PPR plastic pipe, and the water pipe is covered with an insulation layer to reduce temperature loss; the water bath 2 is preferably made of 304 stainless steel.
[0044] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the circulation pipeline 4 includes a first pipe 5 and a second pipe 6; one end of the first pipe 5 is connected to a first interface 7 on the water storage tank 1, and the other end is connected to a second interface 8 on the water bath tank 2; one end of the second pipe 6 is connected to a third interface 9 on the water storage tank 1, and the other end is connected to a fourth interface 10 on the water bath tank 2; a water pump is installed on either the first pipe 5 or the second pipe 6. Specifically, in this embodiment of the present invention, the circulation pipeline 4 is divided into a first pipe 5 and a second pipe 6, and the water pump can be installed on either the first pipe 5 or the second pipe 6. The specific location can be selected according to actual process requirements and system layout, and is not limited here, as long as the purpose of circulating and transporting the medium water can be achieved.
[0045] For example, a water pump is installed on the first pipe 5, which connects the first interface 7 of the water storage tank 1 and the second interface 8 of the water bath 2, for transporting heated hot water from the water storage tank 1 to the heat exchanger 3 in the water bath 2. The second pipe 6 connects the third interface 9 of the water storage tank 1 and the fourth interface 10 of the water bath 2, for returning the heat-exchanged water from the water bath 2 to the water storage tank 1 for reheating.
[0046] For ease of understanding, in this embodiment of the present invention, for example, a number of glass containers 11 with open tops are placed in the water bath 2. Each glass container 11 contains a hazardous chemical solution. The open tops of the glass containers 11 facilitate the addition and removal of the hazardous chemical solution. The glass containers 11 can be made of pharmaceutical glass with good chemical stability and transparency, such as borosilicate glass or soda-lime silicate glass. The water bath 2 can simultaneously heat the hazardous chemical solutions in multiple glass containers 11.
[0047] As a preferred embodiment of this utility model, such as Figure 5As shown, a protective cover 12 is installed at the upper end of the water bath 2. The protective cover 12 can effectively prevent operators from accidentally coming into contact with the high-temperature water bath 2 or glass container 11 during the heating process, avoiding safety accidents such as burns. During the heating process, hazardous chemical liquids may splash out due to boiling or violent reactions. The protective cover 12 can prevent liquids from splashing out of the water bath 2, avoiding pollution or corrosion to the surrounding environment and equipment. At the same time, it can also prevent dust, impurities or other foreign objects from falling into the water bath 2, ensuring the purity of the hazardous chemical liquids and the stability of the reaction environment. Preferably, the protective cover 12 includes a first protective plate 13 and a second protective plate 14 that are inclined downwards. The top of the first protective plate 13 is connected to the top of the second protective plate 14, and the bottom of the first protective plate 13 and the second protective plate 14 are located outside the glass container 11. This structure can guide the splashed liquid or vapor to the outside of the water bath 2, avoiding direct contact between the liquid and the glass container 11, thereby reducing the contamination or damage of hazardous chemical liquid caused by liquid splashing, and avoiding affecting the cleaning effect of hazardous chemical liquid. The inclined structure can better cover the upper opening of the glass container 11, preventing foreign objects from entering the container, while reducing heat loss.
[0048] It should be noted that during actual operation, the operator can either directly cover the upper end of the water bath 2 with the protective cover 12, or set a support mechanism at the upper end of the water bath 2 and place the protective cover 12 on top of the support mechanism to isolate the protective cover 12 from the water bath 2. No restriction is imposed here. Preferably, a handle 15 can also be provided on the top of the protective cover 12 to facilitate the operator's movement of the protective cover 12. The protective cover 12 is preferably made of 304 stainless steel.
[0049] Furthermore, a thermostat 16 is installed on the water storage tank 1. The thermostat 16 is connected to the heater and is used to control the temperature of the medium fluid in the water storage tank 1. It should be noted that the thermostat 16 can be equipped with a high-precision temperature sensor, capable of measuring the temperature of the medium fluid in the water storage tank 1 in real time. It can also use existing technology to adjust the power of the heater to ensure the temperature remains stable within a set range of 5°C. It can also be configured to control the water pump, achieving a circulating water pressure accuracy of ±0.01 MPa. In other embodiments, the water storage tank 1 can also be configured with automatic liquid replenishment, overheat protection, low liquid level protection, and audible and visual alarms, etc. No limitations are imposed here; specific configurations can be made using existing technologies according to actual needs. In this embodiment of the invention, the thermostat 16 only needs to achieve precise temperature control.
[0050] In a preferred embodiment of this invention, an insulation structure can be installed on the wall of the water storage tank 1, such as an insulation layer made of rigid polyurethane foam. This insulation layer is placed on the inner wall of the water storage tank 1 to prevent heat loss due to airflow. Simultaneously, a support frame 17 can be installed at the bottom of the water bath 2, and an end cap 18 can be movably installed at the top of the water storage tank 1. The support frame 17 can be customized according to the shape and size of the water bath 2, and can be a frame or grid structure to provide uniform support. The movable end cap 18 can be connected to the top of the water storage tank 1 by bolts, clips, or magnets. A sealing gasket or sealing ring can also be installed between the end cap 18 and the water storage tank 1 to ensure that water vapor in the water storage tank 1 does not leak during heating. The movable end cap 18 facilitates regular inspection of the heater's operating status, timely detection and handling of potential faults, and allows for the addition of medium water to the water storage tank 1 by opening the end cap 18.
[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model. It should be noted that the structures or components illustrated in the accompanying drawings are not necessarily drawn to scale, and descriptions of well-known components, processing techniques, and processes are omitted to avoid unnecessarily limiting the utility model.
