Description

Technical Field

[0001] The utility model relates to the technical field of chemical additives, in particular to a heat transfer oil system which utilizes a single heat source to accurately control the heat temperatures of multiple devices. Background Art

[0002] A thermal oil boiler is a boiler that uses thermal oil for heating. Thermal oil, also known as organic heat carrier or heat medium oil, has been used as an intermediate heat transfer medium in industrial heat exchange processes for more than 50 years. A direct-flow boiler developed based on a forced circulation design concept generally uses coal, oil, or gas as fuel and thermal oil as the medium. A hot oil circulation pump is used to force the medium into liquid phase circulation, transferring the heat energy to the heat-consuming equipment and then returning it to the heating furnace for reheating. It has the advantages of achieving high operating temperatures at low pressures and being able to perform high-precision control over the medium operation.

[0003] In the existing technology, in chemical additive production plants, generally, a plant uses one thermal oil boiler, which can only operate at one temperature. However, in actual production, different equipment and processes usually use different temperatures. If each different temperature equipment corresponds to a boiler, it will result in increased investment and larger space occupation. The method of using valves to control the flow rate will not only result in uneven temperature, but also may cause decomposition of heat-sensitive materials. Therefore, we propose a thermal oil system that uses a single heat source to accurately control the heat temperature of multiple equipment. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art. In chemical additive production plants, generally, one plant uses one thermal oil boiler, which can only operate at one temperature. However, in actual production, different equipment and processes usually use different temperatures. If each different temperature equipment corresponds to a boiler, it will result in increased investment and larger occupied space. The method of using valves to control the flow rate will result in uneven temperature and may cause decomposition of heat-sensitive materials.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A thermal oil system that uses a single heat source to accurately control the heat temperature of multiple devices includes a thermal oil boiler body. Three first oil outlet valves are evenly spaced on the outer side of the thermal oil boiler body, and a first oil return valve is provided on one side of the first oil outlet valve. A temporary storage tank for temporarily storing the thermal oil is provided on the side of the first oil outlet valve and the first oil return valve away from the thermal oil boiler body.

[0007] As a preferred solution of the present invention, the thermal oil boiler body further includes a fixing frame fixedly connected to the bottom of the thermal oil boiler body for support, and a base is installed at the bottom of the fixing frame, and the fixing frame is fixedly connected to the top of the base.

[0008] As a preferred solution of the present invention, the first oil delivery valve also includes a first delivery pipe connected to the temporary storage tank, and a first sealing rubber ring for sealing with the temporary storage tank is provided at one end of the first delivery pipe away from the first oil delivery valve and located on the inner side of the temporary storage tank.

[0009] As a preferred solution of the present invention, the first oil return valve also includes a second delivery pipe connected to the temporary storage tank, and a first sealing rubber ring for sealing with the temporary storage tank is provided at one end of the first delivery pipe away from the first oil return valve and located on the inner side of the temporary storage tank.

[0010] As a preferred solution of the present invention, a heat pump for transporting thermal oil to the thermal oil boiler body is also installed inside the temporary storage tank, and an oil pipe for transporting thermal oil is also provided on the top of the heat pump, and the oil pipe is fixedly connected to the second delivery pipe.

[0011] As a preferred solution of the present invention, the temporary storage tank also includes a heating pipe installed on the inner side of the temporary storage tank, an insulation layer is installed on the inner side of the heating pipe, and a temperature sensor for sensing temperature changes is installed on the inner side of the insulation layer.

[0012] The technical effect of adopting the above further solution is: the temperature inside the temporary storage tank can be effectively sensed by the temperature sensor, so that the internal heat transfer oil can be effectively insulated in conjunction with the insulation layer and the heating pipe, thereby facilitating production at different temperatures.

[0013] As a preferred solution of the present invention, a second oil outlet valve is provided at the bottom of the temporary storage tank, a third delivery pipe is provided at the bottom of the second oil outlet valve, a second oil return valve is provided on one side of the second oil outlet valve, and a fourth delivery pipe is provided at the bottom of the second oil return valve.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In the present invention, through the provision of a temporary storage tank, the temporary storage tank can effectively temporarily store the heat-conducting oil in the heat-conducting oil boiler body, so that heat-conducting oil of different temperatures enters different temporary storage tanks, which is convenient for use by different equipment and different processes. The temperature sensor can effectively sense the temperature of the heat-conducting oil, and thus cooperate with the heating pipe and the insulation layer to achieve temporary storage of the heat-conducting oil, so that different equipment and different processes can be supplied with heat-conducting oil in a timely manner when they need to use it.

[0024] Example 1

[0025] like Figure 1-3 As shown, the utility model provides a technical solution: a thermal oil system that uses a single heat source to accurately control the heating temperature of multiple devices, including a thermal oil boiler body 1, three first oil outlet valves 2 are evenly arranged on the outer side of the thermal oil boiler body 1, and a first oil return valve 3 is arranged on one side of the first oil outlet valve 2, and a temporary storage tank 4 for temporarily storing the thermal oil is arranged on the side of the first oil outlet valve 2 and the first oil return valve 3 away from the thermal oil boiler body 1, which can effectively temporarily store the thermal oil.

[0026] Example 2

[0027] like Figure 1-3 As shown, the thermal oil boiler body 1 also includes a fixing frame 11 fixedly connected to the bottom of the thermal oil boiler body 1 for support, and a base 12 is installed at the bottom of the fixing frame 11. The fixing frame 11 is fixedly connected to the top of the base 12, which can effectively support the thermal oil boiler body 1 to ensure the stability of the thermal oil boiler body 1.

[0028] The first oil outlet valve 2 also includes a first delivery pipe 21 connected to the temporary storage tank 4, and a first sealing rubber ring 22 for sealing with the temporary storage tank 4 is provided at one end of the first delivery pipe 21 away from the first oil outlet valve 2 and located on the inner side of the temporary storage tank 4. The first delivery pipe 21 can facilitate the delivery of the thermal oil in the thermal oil boiler body 1 to the temporary storage tank 4.

[0029] The first oil return valve 3 also includes a second delivery pipe 31 connected to the temporary storage tank 4. A second sealing rubber ring 32 for sealing with the temporary storage tank 4 is sleeved on the end of the second delivery pipe 31 away from the first oil return valve 3 and located on the inner side of the temporary storage tank 4, thereby facilitating the delivery of the thermal oil in the temporary storage tank 4 to the thermal oil boiler body 1.

[0030] A heat pump 41 for transporting the thermal oil to the thermal oil boiler body 1 is also installed inside the temporary storage tank 4. An oil pipe 42 for transporting the thermal oil is also provided on the top of the heat pump 41. The oil pipe 42 is fixedly connected to the second delivery pipe 31 to facilitate the reflux of the thermal oil.

[0031] The temporary storage tank 4 also includes a heating pipe 43 installed inside the temporary storage tank 4, and an insulation layer 44 is installed inside the heating pipe 43. A temperature sensor 45 for sensing temperature changes is installed inside the insulation layer 44, which can effectively preserve the thermal oil.

[0032] A second oil outlet valve 5 is provided at the bottom of the temporary storage tank 4, and a third delivery pipe 51 is provided at the bottom of the second oil outlet valve 5.

[0033] The working process of the utility model is as follows: when using a heat-conducting oil system that uses a single heat source to accurately control the heat temperature of multiple devices for the production of chemical additives, first, the heat-conducting oil boiler body 1 is turned on. After turning on, the heat-conducting oil boiler body 1 heats the heat-conducting oil. When the temperature of the heat-conducting oil reaches the set temperature, the heat-conducting oil enters the first delivery pipe 21 through the first oil outlet valve 2, and then enters the temporary storage tank 4. When the temporary storage tank 4 stores the required amount, the first oil outlet valve 2 is closed, and the heat-conducting oil in the heat-conducting oil boiler body 1 continues to be heated. After reaching the set temperature again, it enters another temporary storage tank 4 through another first oil outlet valve 2 and the first delivery pipe 21. , until the temporary storage tank 4 is filled with heat transfer oil of different temperatures. When the heat transfer oil enters the temporary storage tank 4, the temperature sensor 45 detects the temperature change. When the temperature is lower than the set value, the heating pipe 43 is turned on, and it is turned off when it is close to the maximum set value. At the same time, the insulation layer 44 also delays the temperature loss. When the processing equipment needs heat transfer oil, the second oil outlet valve 5 at the bottom of the corresponding temporary storage tank 4 is opened, and the heat transfer oil enters the interior of the equipment through the third delivery pipe 51. Through design, the utility model can effectively use a single heat source to control multiple devices, accurately control the operation at the temperature required by the device, and solve the heating problem in production with a lower cost.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
