Description

Technical Field

[0001] The utility model mainly relates to the technical field of pipeline detection, and in particular to a foreign body monitoring device in an annular space within a pipe. Background Art

[0002] Oxides are generated during the production process of electric furnaces, melting furnaces and smelting furnaces. A very small amount of oxides, dust or ash is brought into the bottom of the central axis bellows by the negative pressure airflow of the vacuum pump and accumulated. Too much accumulation of foreign matter will affect the continuous operation of the equipment and the quality of subsequent products. At the same time, dismantling and cleaning the equipment after shutdown will also cause larger particles to fall to the bottom of the bellows. Each time, manual work is required to go to the base of the equipment, use tools to disassemble the flange of the large axis bellows, check and clean it to ensure the normal operation of the equipment. However, there is also a situation where the crucible bellows is clean after opening and no cleaning is required, resulting in a waste of resources. On this basis, a foreign matter monitoring device for the annular space in the tube is proposed. Utility Model Content

However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0028] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] It should be noted that the structures not introduced in the present invention do not involve the design points and improvement directions of the present invention, and all adopt the existing technology. At the same time, the content of the above background technology belongs to the technical cognition scope of the utility model inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute the prior art. Example 1

[0030] Reference Figure 1-5 , this embodiment provides a device for monitoring foreign matter in an annular space in a pipe, including a monitoring flange 1, which is arranged in an annular shape, and a central axis 2 is embedded in the interior thereof. In this embodiment, the annular structure of the monitoring flange 1 is not specifically limited. A truncated cone structure is adopted in this application, but the monitoring flange 1 may also adopt a circular structure, and an object to be detected such as the central axis 2 may be placed in the interior thereof;

[0031] At least two groups of sensor bolts 3 are arranged around the side of the monitoring flange 1. Each group of the sensor bolts 3 is provided with a visual sensor 4. The visual sensor 4 is electrically connected to the upper industrial control computer. The visual sensor 4 transmits the collected signal to the upper industrial control computer, which is a conventional technical means and will not be elaborated. The invention point of the utility model lies in the structural setting of the foreign body monitoring device in the annular space of the pipe.

[0032] The monitoring flange 1 can be an integrally formed setting, but considering the convenient disassembly and assembly of the monitoring flange 1, the monitoring flange 1 is spliced ​​by a first flange 11 and a second flange 12, so that a C-shaped cavity arranged on the outer circle of the central axis 2 is formed inside the monitoring flange 1, and it is convenient to divide the monitoring flange 1 into three sections of upper, middle and lower areas. In this embodiment, a split structure of the monitoring flange 1 is provided, and is not limited to the above structure. The monitoring flange 1 provided in this embodiment can also be spliced ​​by multiple flanges, and a C-shaped cavity arranged on the outer circle of the central axis 2 is formed inside it.

[0033] In a preferred embodiment, the sensor bolt 3 is provided with a notch 31 for installing the line of the visual sensor 4. After the visual sensor 4 is installed, it is sealed, and the wiring opening of the visual sensor 4 and the starting point of the thread of the sensor bolt 3 are kept consistent.

[0034] Among them, the visual sensor 4 is preferably set to three groups, which can be implemented using ordinary sensors. The visual sensor 4 has high temperature resistance and is sealed during installation to achieve 360-degree no-dead-angle monitoring in the annular space. If two groups of visual sensors 4 are used, higher requirements are placed on the visual sensor 4, which can meet the 360-degree no-dead-angle monitoring in the annular space. The visual sensor 4 is controlled by software to collect the real-time situation of the annular space in the central axis 2, and the identified signal is transmitted to the upper industrial computer. The operator can remotely obtain information and select and clean the flange bellows that need to be cleaned.

[0035] In a preferred embodiment, a sealing ring 5 is provided at the connection between the sensor bolt 3 and the monitoring flange 1, wherein the sealing ring 5 is preferably a polytetrafluoroethylene sealing gasket. Since the polytetrafluoroethylene sealing gasket has good elasticity, attention should be paid to controlling the torque during assembly so that its opening faces downward and is adapted to the notch 31.

[0036] This embodiment also includes a plurality of fasteners 6 arranged around and through the monitoring flange 1, and the monitoring flange 1 is connected to the bellows flange 7 and the base 8 (the base of the product to be tested, such as the crucible base) through the plurality of fasteners 6. This connection method realizes the installation of the foreign body monitoring device in the annular space in the pipe, and a silicone sealing gasket is provided at the connection between the monitoring flange 1 and the base 8.

[0037] In a preferred embodiment, the fastener 6 includes a hexagonal top screw 61 connected to the base 8, and the top surface of the hexagonal top screw 61 is provided with a threaded stud 62 that is adapted to it and has a cavity inside. The top thread of the threaded stud 62 is connected to an external hexagonal bolt 63, and the external hexagonal bolt 63 is arranged on the surface of the bellows flange 7.

[0038] During the specific installation, the hexagon socket top screw 61 is set on the base 8, and the thread glue is applied. The hexagon socket top screw 61 is tightened. The bottom surface of the thread stud 62 is set with a flat mouth. The lower part of the thread stud 62 (the connection with the hexagon socket top screw 61) is also applied with thread glue. The thread stud 62 and the hexagon socket top screw 61 are tightened and fastened into one after drying.

[0039] The upper part of the threaded stud 62 is threadedly connected with an external hexagonal bolt 63 connected to the bellows flange 7. The monitoring flange 1 can be removed quickly and conveniently by unscrewing the external hexagonal bolt 63 at the bellows flange 7.

[0040] This embodiment further includes a wire trough guard plate 9 disposed on the bottom surface of the monitoring flange 1 , and the wire trough guard plate 9 is surrounded by a plurality of sets of bolts 10 and disposed on the bottom surface of the monitoring flange 1 .

[0041] The monitoring device is installed between the base 8 and the bellows flange 7, and the central axis 2 is embedded in the monitoring device. 360-degree monitoring without blind spots is achieved through at least two sets of visual sensors 3 to ensure the normal operation of the furnace body. The visual sensor 3 transmits the monitoring signal to the upper industrial computer, and the operator determines whether the equipment needs to be cleaned, thereby reducing the man-hours and operation and maintenance costs of the furnace body.

It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
