Description

Technical Field

[0001] The utility model relates to the technical field of petroleum electric heating devices, in particular to a petroleum electric heating device. Background Art

[0002] The oil electric heating device, also known as the oil temperature controller, is a large-scale hot oil temperature control equipment that can heat the heat transfer oil to 350 degrees Celsius at a lower operating pressure.

[0003] For example, an oil electric heating device with the authorization announcement number "CN2360598Y" adopts a mineral insulated heating cable wound on an iron core tube, which is covered with a steel shell on the outside. The steel shell is connected to the plate with a flange, and the explosion-proof junction box is installed on the blind plate. It is also equipped with a gas protection thermostat, an oil temperature control sensor, and a dry-burning temperature limit sensor. It has a novel structure, a long service life, high thermal efficiency, fast heating, energy saving, safety and reliability. However, when the oil electric heating device is used, the interior is an integral straight pipe. In order to ensure a large flow rate, the inner diameter is large, and the water flow cannot stay through the straight pipe, and the water flow inside the straight pipe cannot be instantly heated to the specified temperature. This requires the water flow to pass through multiple times, which increases the working cost of the oil electric heating device and reduces the working efficiency of the oil electric heating device. Utility Model Content

[0007] Preferably, the conveying structure includes a circular tube and a circular disc, the outer walls of the two circular tubes are respectively fixedly connected to the front and rear sides of the outer shell, the inner side of the circular tube is connected to the outer side of the circular disc, the inner side of the circular disc is connected to a plurality of straight tubes, the upper and lower sides of the inner wall of the straight tube are respectively fixedly connected to curved blocks on the front and rear sides, and the inner sides of the plurality of curved blocks are all fixedly connected to straight rods.

[0008] Preferably, the outer wall end of the circular tube is fixedly connected to the inner wall of the flange.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Embodiment 1:

[0021] See also Figure 1-5In the present embodiment, a petroleum electric heating device includes an outer shell 1 and a curved plate 6. The front and rear sides of the bottom of the outer shell 1 are fixedly connected to the inner wall of the curved plate 6 respectively. The left and right sides of the bottom of the curved plate 6 are fixedly connected to a base 7 respectively. The curved plate 6 cooperates with the base 7 to support the outer shell 1. The front and rear sides of the outer shell 1 are connected to a conveying structure 2. The top of the outer shell 1 is connected to a control structure 3. A plurality of heaters 4 are fixedly connected to the front of the outer shell 1. The model of the heater 4 is selected according to the use requirements. The outer wall end of the conveying structure 2 is connected to a flange 5.

[0022] The conveying structure 2 includes a circular tube 201 and a circular disc 202. The outer walls of the two circular tubes 201 are respectively fixedly connected to the front and rear sides of the housing 1. The inner side of the circular tube 201 is connected to the outer side of the circular disc 202. The inside of the circular disc 202 is hollow and can store water. The inner side of the circular disc 202 is connected to a plurality of straight tubes 203. The inner walls of the straight tubes 203 are respectively fixedly connected to curved blocks 204 on the upper and lower sides and the front and rear sides. The inner sides of the plurality of curved blocks 204 are all fixedly connected to straight rods 205. The straight tubes 203 cooperate with the straight rods 205 to form a sandwich pipe. The outer wall end of the circular tube 201 is fixedly connected to the inner wall of the flange 5.

[0023] The water source is sent to the disc 202 at the front circular tube 201 through the conveying structure 2, and the disc 202 sends the water source into the straight tube 203. Since the inner wall of the straight tube 203 is provided with a straight rod 205, the water flow rate of the straight tube 203 is reduced, and multiple straight tubes 203 will not affect the water flow rate while ensuring that the internal water source is quickly heated. The heated water source is collected in the rear circular disk 202 and then flows out of the rear circular tube 201, which changes the original heating form, reduces the working cost of the petroleum electric heating device, and improves the working efficiency of the petroleum electric heating device.

[0024] The rear of the outer wall of the heater 4 is fixedly connected to the rear of the inner wall of the shell 1. The control structure 3 includes a vertical tube 301 and a circular ring 302. The bottom of the vertical tube 301 is connected to the top of the shell 1. The inner wall of the vertical tube 301 is fixedly connected to the outer wall of the circular ring 302. A plug 304 is inserted into the top of the inner wall of the vertical tube 301. The plug 304 is a rubber block. A spring 303 is fixedly connected to the top of the circular ring 302. The top of the spring 303 is fixedly connected to the bottom of the plug 304. When the plug 304 moves upward, it rebounds due to the elastic force of the spring 303.

[0025] Working principle:

[0026] Oil electric heating device installation:

[0027] The plug 304 is pulled upward to disengage from the top of the vertical pipe 301, and then the oil is poured into the interior of the housing 1 at the top of the vertical pipe 301. The plug 304 is then released, and the spring 303 provides a rebound force to insert the plug 304 back into the vertical pipe 301. The flanges 5 on the front and rear sides are fixed with the flanges of the external pipeline by bolts, and then the heater 4 is connected to the external power supply.

[0028] Oil electric heating device use:

[0029] The heater 4 is powered on to heat the oil on the inner wall of the shell 1, and then the water pipe sends the water source from the front circular tube 201 to the disc 202, and the disc 202 sends the water source into the straight tube 203. Since the inner wall of the straight tube 203 is provided with a straight rod 205, the water flow rate of the straight tube 203 is reduced, and multiple straight tubes 203 will not affect the water flow rate while ensuring that the internal water source is quickly heated. The heated water source is collected in the rear disc 202 and then flows out of the rear circular tube 201. When gas is generated on the inner wall of the shell 1, the gas will push the plug 304 upward and out of the vertical tube 301, so that the gas inside the shell 1 is discharged, and then the spring 303 provides a rebound force to move the plug 304 downward and insert it back into the vertical tube 301.

[0030] Embodiment 2:

[0031] See also Figure 1-5 In the present embodiment, a petroleum electric heating device further comprises a sleeve ring 8, wherein the inner sides of the plurality of sleeve rings 8 are respectively fixedly connected to the upper left and right sides of the base 7.

[0032] Working principle:

[0033] When the petroleum electric heating device is transported, the external hook can pass through the inner wall of the ring 8, and then the pull rope pulls the hook upward to move the ring 8 upward, and the moving ring 8 cooperates with the base 7 and the shell 1 to move upward to complete the transportation.

[0034] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
