Description

Technical Field

[0001] The utility model belongs to the technical field of heat transfer oil, in particular to a heat transfer oil injection device. Background Art

[0002] As a high-temperature heat carrier, heat transfer oil exchanges heat with heat-using equipment during the paste making and asphalt melting production process to play a heating role. After the heat exchange, the heat transfer oil returns to the heat transfer oil heating station to be reheated, and then pressurized and sent to various heat users for recycling. Due to the recycling of heat transfer oil, heating will cause carbonization and oxidation of the heat transfer oil, resulting in loss. To ensure normal production, the system needs to be continuously replenished with heat transfer oil. In the heat transfer oil heating station, the pipeline system needs to be filled with heat transfer oil at the beginning of production. After the system has been running for a period of time, the heat transfer oil needs to be replenished. Since the amount of heat transfer oil added is relatively large, and the finished heat transfer oil is often packaged in barrels, it cannot be filled in a mechanized way. Therefore, filling the system with heat transfer oil has become a relatively labor-intensive task in the heat transfer oil heating station.

[0003] However, there are some problems with the prior art: in the past, when filling the thermal oil, due to the high weight of the barreled thermal oil, it is labor-intensive to move the barreled thermal oil to the upper part of the thermal oil storage tank, so it is generally pumped out. However, when using the pump, it is impossible to determine whether the thermal oil is full. When filling the oil, you need to pay attention at all times to prevent the thermal oil from overflowing due to excessive addition. In addition, the subsequent filling of the thermal oil is more troublesome and the oil pump needs to be restarted for filling. Therefore, we propose a thermal oil filling device. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a thermal oil filling device, which extracts the thermal oil from the thermal oil barrel into a quantitative oil tank through an oil pump, so that the thermal oil can be filled up just right without causing waste of thermal oil.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 5 As shown, a heat transfer oil filling device provided by an embodiment of the utility model includes a base 1, which is rectangular and is welded by multiple groups of stainless steel plates. The main function of the base 1 is to support the entire device.

[0025] A bracket 2 is fixedly connected to the base 1. The bracket 2 is welded from a plurality of groups of stainless steel pipes. An oil pump 3 is fixedly connected to the bracket 2. The oil pump 3 is used to extract the heat transfer oil from the heat transfer oil barrel.

[0026] An oil extraction pipe 4 is fixedly connected to one side of the oil pump 3. The oil extraction pipe 4 is a rubber hose. Of course, its material is not limited to rubber hose, and it can also be set to other oleophobic materials. The main function of the oil extraction pipe 4 is to guide the heat transfer oil so that the heat transfer oil can be extracted from the heat transfer oil barrel by the oil pump 3.

[0027] A connecting pipe 5 is fixedly connected to the other side of the oil pump 3. An exhaust assembly 6 is arranged at one end of the connecting pipe 5. The exhaust assembly 6 includes an exhaust pipe 601. The exhaust pipe 601 is fixedly connected to the connecting pipe 5. An exhaust port 602 is arranged at the upper end of the exhaust pipe 601.

[0028] When the oil pump 3 extracts the thermal oil through the oil extraction pipe 4, the air in the oil extraction pipe 4 will move to the thermal oil furnace. An exhaust pipe 601 is arranged on the connecting pipe 5, so that the air in the oil extraction pipe 4 can be discharged during the oil extraction process, which can effectively prevent the air from flowing into the thermal oil furnace, causing the thermal oil to be disconnected and affecting the thermal efficiency of the thermal oil.

[0029] A control component 603 is provided in the exhaust pipe 601, and the control component 603 is used to control the switch of the exhaust pipe 601. The control component 603 includes a rotating shaft 6031, and a threaded hole is opened on one side of the exhaust port 602. The rotating shaft 6031 is rotatably connected in the hole. One end of the rotating shaft 6031 is rotatably connected to the valve core 6032, and the other end of the rotating shaft 6031 is fixedly connected to the handle 6033.

[0030] By turning the handle 6033 to drive the rotating shaft 6031 to rotate, the rotating shaft 6031 will drive the valve core 6032 to move, so that the valve core 6032 blocks the exhaust pipe 601, so that when the air in the oil extraction pipe 4 is exhausted, the exhaust pipe 601 can be blocked in time to prevent the heat transfer oil from flowing out of the exhaust port 602.

[0031] An oil tank 7 is provided at the other end of the connecting pipe 5. The oil tank 7 is rectangular and made of stainless steel. The capacity of the oil tank 7 is the same as the thermal oil used in the thermal oil furnace. An oil drain pipe 8 is fixedly connected to the upper end of the oil tank 7, and an oil storage assembly 9 is provided at one end of the oil drain pipe 8.

[0032] The oil storage assembly 9 includes an oil storage tank 901, which is fixedly connected to the base 1, and an oil drain pipe 8 is fixedly connected to one side of the oil storage tank 901. A hole is opened on one side of the oil storage tank 901, and an oil outlet pipe 902 is fixedly connected to the inner wall of the hole. The oil outlet pipe 902 is fixedly connected to the oil supply pipe 10.

[0033] After the oil tank 7 is filled with oil, the excess heat transfer oil will enter the oil storage tank 901 through the oil discharge pipe 8 for storage. When in use, the valve 11 on the oil outlet pipe 902 can be opened to add the heat transfer oil into the heat transfer oil furnace.

[0034] A plugging assembly 12 is provided on the oil outlet pipe 902, and the plugging assembly 12 includes an outer shell 121, and the outer shell 121 is fixedly connected to the oil outlet pipe 902. An oil outlet 122 is fixedly connected inside the outer shell 121, and a limiting ring 123 is fixedly connected below the oil outlet 122. An oil outlet hole is opened on the limiting ring 123, and a float 124 is provided between the limiting ring 123 and the oil outlet 122.

[0035] When the heat transfer oil is added to the heat transfer oil furnace from the oil storage tank 901, the float 124 is forced downward to the limit ring 123. At this time, the heat transfer oil will flow out from the oil outlet hole on the limit ring 123. When the heat transfer oil is added, the float 124 will rise due to the buoyancy and block the oil outlet 122. The heat transfer oil below cannot enter the oil storage tank 901, effectively avoiding the backflow of the heat transfer oil and preventing the backflow of the heat transfer oil from contaminating the heat transfer oil in the oil storage tank 901.

[0036] The bottom end of the oil tank 7 is fixedly connected with an oil supply pipe 10, which runs through the base 1 and is used to add oil to the heat transfer oil furnace.

[0037] The working principle of the utility model is as follows:

[0038] The utility model uses the oil pump 3 to extract the heat transfer oil from the heat transfer oil barrel through the oil pumping pipe 4. During the extraction process, the air in the oil pumping pipe 4 will be discharged from the exhaust pipe 601. After the air is discharged, the valve core 6032 is blocked by turning the handle 6033 to block the exhaust pipe 601, and then the valve 11 of the connecting pipe 5 is opened, and the heat transfer oil will flow into the oil tank 7. After the oil tank 7 is filled, the excess heat transfer oil will flow into the oil storage tank 901 for filling. Then, the oil pump 3 is closed, and the valve 11 on the oil supply pipe 10 is opened to add the heat transfer oil in the oil tank 7 to the heat transfer oil furnace to complete the quantitative oil filling.

[0039] The above embodiments are only used to help understand the method and core idea of ​​the utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
