Description

Technical Field

[0001] This utility model relates to the field of industrial temperature control technology, specifically a high-temperature oil temperature controller with an oil replenishment device. Background Technology

[0002] A high-temperature oil temperature controller is an industrial temperature control device that uses heat transfer oil as a circulating medium. It heats the heat transfer oil to a maximum of over 350°C through an electric heater and forces it to circulate through a high-temperature pump. This provides a stable and uniform high-temperature heat source for industrial equipment such as reaction vessels, calendering rollers, and molds. It is widely used in fields requiring high-temperature processes, such as plastics, chemicals, and new energy.

[0003] In current technology, high-temperature oil temperature controllers require manual oil replenishment at regular intervals. This method is inefficient for real-time oil replenishment. Furthermore, if the oil replenishment point becomes blocked, it can easily lead to excessive oil replenishment, affecting the device's performance.

[0004] However, the applicant believes that the shortcomings are: 1. During use, the heat transfer oil inside the device tends to evaporate and decrease with use, and when oil needs to be replenished, it usually requires manual replenishment by the staff, which is quite troublesome; 2. If the float ball becomes blocked during the oil replenishment process, it is easy to cause excessive oil replenishment, thereby affecting the working effect of the device.

[0005] To address this issue, we propose a high-temperature oil temperature controller with an oil replenishment device. Utility Model Content

[0006] The purpose of this invention is to provide a high-temperature oil temperature controller with an oil replenishment device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature oil temperature controller with an oil replenishment device, comprising a main body, the main body including an oil storage tank, an oil inlet pipe, a connecting pipe, a plunger pump, an expansion tank, an overflow pipe, and an overflow box; and a float pipe, the float pipe including a lifting chamber, an oil outlet, a buoyancy groove, a float ball, and an auxiliary slider.

[0008] Preferably, the main body of the device includes an oil storage tank, an oil inlet pipe is fixedly installed on one side of the top of the oil storage tank near the edge, and a connecting pipe is threadedly connected to one end of the oil storage tank by bolts.

[0009] Preferably, a filter screen is snapped onto the inner side of the connecting pipe, a fixed base is welded onto the bottom outer side of the oil tank, and a plunger pump is snapped onto the outer side of one end of the oil tank.

[0010] Preferably, a fixed pipe is inserted and installed at the connection between the plunger pump and the oil tank, an oil delivery pipe is fixedly installed at the bottom of the plunger pump, an auxiliary pipe is welded to one end of the oil delivery pipe, and an expansion tank is fixedly connected to the other end of the auxiliary pipe.

[0011] Preferably, a stabilizing block is provided on the outside of the expansion tank, and the stabilizing block is connected and fixed to the expansion tank by bolts. An overflow pipe is provided on one side of the expansion tank at the same level as the float, and an overflow box is fixedly installed at one end of the overflow pipe.

[0012] Preferably, a glass plate is fixedly installed on the middle part of the surface of the overflow tank, and a float tube is fixedly installed on the inner side and top of the expansion tank, with a lifting cavity opened in the middle part of the inner side of the float tube.

[0013] Preferably, the inner wall of the lifting chamber has oil outlets on both sides near the top, the bottom surface of the float tube has a buoyancy groove in the middle, a float ball is slidably installed on the top of the inner side of the float tube, and auxiliary sliders are fixedly installed on both sides of the top of the float ball.

[0014] This utility model provides a high-temperature oil temperature controller with an oil replenishment device, which has the following beneficial effects: The float tube enables automatic oil replenishment during operation. When the heat transfer oil in the expansion tank evaporates and drops, the float ball slides downwards under gravity via an auxiliary slider. This allows oil from the storage tank to enter the float tube through the auxiliary tube and then into the expansion tank through the oil outlet on the inner wall of the float tube. When the heat transfer oil in the expansion tank rises, it enters the float tube through the buoyancy groove, pushing the float ball upwards. This facilitates the blocking of the oil inlet and enables automatic oil replenishment.

[0015] The overflow box allows excess heat transfer oil to flow through the expansion tank and into the overflow pipe via an overflow port on one side. The oil is then collected inside the overflow box by the overflow pipe. This allows staff to observe the overflow box through a glass plate, facilitating timely maintenance of the equipment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment proposes a high-temperature oil temperature controller with an oil replenishment device. Example 1

[0021] like Figures 1 to 4As shown, this embodiment proposes a high-temperature oil temperature controller with an oil replenishment device, including a main body 1. The main body 1 includes an oil tank 2, an oil inlet pipe 3, a connecting pipe 4, a plunger pump 7, an expansion tank 11, an overflow pipe 13, and an overflow box 14; a float pipe 16, which includes a lifting chamber 17, an oil outlet 18, a buoyancy groove 19, a float ball 20, and an auxiliary slider 21. The main body 1 includes an oil tank 2. An oil inlet pipe 3 is fixedly installed on one side of the top of the oil tank 2 near the edge. One end of the oil tank 2 is connected to a connecting pipe 4 by bolt thread. A filter screen 5 is snapped onto the inner side of the connecting pipe 4. A fixed bottom is welded to the outer bottom of the oil tank 2. A plunger pump 7 is snapped onto the outer side of one end of the oil tank 2. A fixed pipe 8 is inserted and installed at the connection between the plunger pump 7 and the oil tank 2. An oil delivery pipe 9 is fixedly installed at the bottom end of the plunger pump 7. An auxiliary pipe 10 is welded to one end of the oil delivery pipe 9. An expansion tank 11 is fixedly connected to the other end of the auxiliary pipe 10. A stabilizing block 12 is provided on the outer side of the expansion tank 11. The stabilizing block 12 is connected and fixed to the expansion tank 11 by bolts. An overflow pipe 13 is provided on one side of the expansion tank 11 at the same level as the float 20. An overflow box 14 is fixedly installed at one end of the overflow pipe 13. A glass plate 15 is fixedly installed on the middle part of the surface of the overflow box 14. The oil storage tank 2 can be replenished with heat transfer oil through the oil inlet pipe 3. The heat transfer oil in the oil storage tank 2 can enter the inside of the expansion tank 11 through the auxiliary pipe 10. The expansion tank 11 can be fixed by the stabilizing block 12 and bolts to keep the expansion tank more stable during use. An overflow port is opened on one side surface of the expansion tank 11 at the same level as the float 20. The collection of heat transfer oil inside the overflow tank 14 can be observed through the glass plate 15.

[0022] The plunger pump 7 used in this application is model SPECK-ZP30, which is a product that can be purchased directly on the market. Its principle and connection method are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0023] In the above embodiment, when the float 20 is stuck inside the float tube 16, the heat transfer oil in the oil tank 2 will continuously enter the inside of the expansion tank 11. At this time, the heat transfer oil exceeding the standard position will enter the inside of the overflow pipe 13 through the overflow port, and then be introduced into the inside of the overflow box 14 through the overflow pipe 13. At this time, the staff can observe the heat transfer oil entering the inside of the overflow box 14 through the glass plate 15 provided on the surface of the overflow box 14, thereby providing a fault warning for the device and facilitating the maintenance of the device.

[0024] Example 2 like Figure 4 and Figure 5As shown, based on the same concept as the above embodiment, this embodiment also proposes: a float tube 16 is fixedly installed at the inner side and top of the expansion tank 11, a lifting cavity 17 is opened in the middle part of the inner side of the float tube 16, oil outlets 18 are opened on both sides of the inner wall of the lifting cavity 17 near the top, a buoyancy groove 19 is opened in the middle part of the bottom surface of the float tube 16, a float ball 20 is slidably installed at the top of the inner side of the float tube 16, and auxiliary sliders 21 are fixedly installed on both sides of the top of the float ball 20. The inner wall of the float tube 16 is provided with a sliding groove. The float ball 20 can move inside the float tube 16 through the lifting chamber 17 to perform oil replenishment. The float ball 20 can be more stable when sliding to replenish oil through the auxiliary slider 21, and the situation of the float ball getting stuck can be reduced.

[0025] In the above embodiment, when the heat transfer oil in the expansion tank 11 evaporates and drops, the heat transfer oil in the float tube 16 also drops. At this time, due to the action of gravity, the float ball 20 can slide downward in the sliding groove inside the float tube 16 through the auxiliary slider 21. At this time, the heat transfer oil in the storage tank 2 will enter the float tube 16 through the auxiliary pipe 10, and then enter the inside of the expansion tank 11 through the oil outlet 18. When the heat transfer oil in the expansion tank 11 rises to the bottom of the float tube 16, the heat transfer oil will enter the float tube 16 through the buoyancy groove 19 and push the float ball 20 upward, so that the float ball 20 returns to the top position of the float tube 16, thereby blocking the auxiliary pipe 10 and stopping the oil replenishment work.
