Description

Technical Field

[0001] This utility model relates to the field of temperature sleeve technology, specifically to a shunt temperature sleeve. Background Technology

[0002] Temperature sleeves, also known as thermometer protective sleeves, are key components used to protect temperature sensors in industrial temperature measurement equipment. Currently, in the polysilicon production process, the exhaust gas generated by the reduction furnace contains a large amount of silicon powder. Due to the high flow rate of this medium, it causes severe wear on the resistance temperature gauge sleeve. Existing temperature sleeves are made of 316L hardened and sprayed Stellite, which has a certain degree of wear resistance. However, under high temperature and acidic conditions, its erosion resistance is weak. After the coating peels off due to high temperature and material corrosion, the temperature sleeve wears through and the material leaks out. Utility Model Content

[0003] This invention addresses the problem of corrosion and leakage in current temperature bushings due to the scouring effect of media during use. It provides a flow-diverting temperature bushing that, by incorporating a flow-diverting block, can divert the incoming media, thereby reducing wear caused by the eddies formed before and after the bushing body due to direct impact of the media.

[0004] The technical solution adopted in this utility model is:

[0005] A shunt temperature bushing is provided, comprising:

[0006] The sleeve body; an extension tube, one end of which is located at the end of the sleeve body and communicates with the interior of the sleeve body, and the other end is closed; a step is formed between the outer wall surface of the extension tube and the end face of the sleeve body; multiple through holes are provided on the side wall surface of the extension tube facing the step; a diverter block is located on the outer wall surface of the extension tube and at the step; a screw hole corresponding to the multiple through holes is provided on the outer wall surface of the diverter block facing the extension tube; the side of the diverter block away from the extension tube is an inclined surface; a fixing bolt is located inside the through hole and is threadedly connected to the extension tube through the screw hole, used to connect the extension tube and the sleeve body.

[0007] Optionally, the diverter block is a triangular prism, with the longest edge of the prism at its cross-section connected to the outer wall of the extension pipe.

[0008] Optionally, the minimum distance between the outer walls of two fixing bolts located on the same cross-section of the extension tube is greater than the outer diameter of the thermometer.

[0012] Optionally, the sleeve body is a ceramic sleeve.

[0013] Optionally, the angle between the side wall of the triangular prism facing the extension tube and its two other adjacent outer wall surfaces is 30° to 60°.

[0014] The beneficial effects of this utility model are:

[0015] An extension tube is connected to the end of the sleeve body at the point where the medium flows, with the other end of the extension tube being a closed end, allowing the thermometer to extend into the interior of the extension tube through the sleeve body. A step is formed between the outer wall of the extension tube and the end of the sleeve body facing the extension tube, and multiple through holes are formed on the side wall of the extension tube facing the step, connecting to the interior of the extension tube.

[0029] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0030] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0031] Example

[0032] Please see Figure 1-4As shown, this embodiment discloses a flow-diverting temperature sleeve, including a sleeve body 1, an extension tube 2, a flow-diverting block 3, and fixing bolts 4. Specifically, the extension tube 2 is provided at the end of the sleeve body 1 located in the medium flow region. One end of the extension tube 2 is connected to the interior of the sleeve body 1, and the other end is a closed end. A step is formed between the outer wall surface of the extension tube 2 and the end of the sleeve body 1 facing the extension tube 2, and the flow-diverting block 3 is disposed on the step. Multiple through holes 20 are opened on the side wall surface of the extension tube 2 facing the step, and the multiple through holes 20 are connected to the interior of the extension tube 2. A fixing bolt 4 is provided inside each through hole 20. Threaded holes 30 corresponding to and connected to the multiple through holes 20 are opened on the side wall surface of the flow-diverting block 3 facing the extension tube 2, so that the fixing bolt 4 inside each through hole 20 can be threadedly connected to the flow-diverting block 3 through the corresponding threaded hole 30, thereby fixing the flow-diverting block 3 to the side wall surface of the extension tube 2. The side wall of the diverter block 3 facing the direction from which the medium flows is set as an inclined surface. When the medium flows to contact and collide with the inclined surface of the diverter block 3, the medium can be diverted, thereby reducing the wear caused by the direct impact of the medium on the eddy currents formed before and after the sleeve body 1.

[0033] Furthermore, in this embodiment, a connecting flange 10 is provided on the outer wall surface of the sleeve body 1 near its other end, for fixing the sleeve body 1 to the medium flow conveying device. In addition, the end of the sleeve body 1 away from the extension tube 2 is an open end, which allows the thermometer to enter the interior of the sleeve body 1 through the opening. Specifically, a thermal resistance temperature core is provided inside the extension tube 2, which can transmit the ambient temperature of the medium in the extension tube 2 and finally display it on the thermometer. The extension tube 2 and the sleeve body 1 are integrally formed. The diverter block 3 is specifically made of high-temperature resistant ceramic material, which can reduce the wear caused by the impact of the medium on the diverter block 3 when the medium is diverted, thereby preventing material leakage and avoiding affecting production safety. In addition, in this embodiment, the fixing bolt 4 is a hexagon socket head cap screw, which is tightened to install the diverter block 3 on the outer wall surface of the extension tube 2.

[0034] In this embodiment, the diversion block 3 is generally shaped like a triangular prism. One side wall of the prism is in contact with the side wall of the extension pipe 2, while the other two side walls are in contact with the flowing medium. It should be noted that among the three side walls of the triangular prism, the side wall connected to the outer wall of the extension pipe 2 has the largest area. Based on this, the remaining two side walls of the triangular prism can divert the oncoming medium.

[0035] Furthermore, the edge of the outer wall of the diverter block 3 facing the extension pipe 2 is flush with the side wall of the extension pipe 2. That is, when the medium passes through the inclined surface of the diverter block 3 and is diverted, the medium will flow directly from the inclined surface of the diverter block 3 towards the outside of the extension pipe 2, and the medium will not continue to collide with the side wall of the extension pipe 2 after impacting the inclined surface of the diverter block 3. In other words, the diverter block 3 can completely cover the side wall of the extension pipe 2 in the direction from which the medium flows, avoiding the collision between the medium and the outer wall of the extension pipe 2, which would cause corrosion of the side wall of the extension pipe 2, thereby preventing the medium from leaking out.

[0036] The minimum distance between the outer walls of the two fixing bolts 4 located on the same cross section of the extension tube 2 must be greater than the outer diameter of the thermometer. That is, when the diverter block 3 is fixedly installed on the side wall of the extension tube 2 by fixing bolts 4, the diverter block 3 is fixed on the extension tube 2 by rotating the fixing bolts 4 located inside the extension tube 2. If the length of the fixing bolts 4 is too long, part of the length of the fixing bolts 4 will be inside the extension tube 2, which will affect the insertion of the thermometer. Therefore, it is necessary to adjust the minimum distance between the outer walls of the two fixing bolts 4 to be greater than the outer diameter of the thermometer, which is equivalent to adjusting the distance between the two through holes 20. If the length of the fixing bolts 4 is too short, the fixing bolts 4 will be completely inside the through hole 20 during the threaded connection with the diverter block 3, which will affect the insertion of the thermometer.

[0037] A sealing gasket 5 is provided between the outer wall of the diverter block 3 and the outer wall of the extension pipe 2. When the diverter block 3 is threadedly connected to the outer wall of the extension pipe 2 by the fixing bolt 4, the diverter block 3 and the extension pipe 2 will squeeze the sealing gasket 5. During the squeezing process, the sealing gasket 5 will fill the gap between the diverter block 3 and the extension pipe 2. It should be noted that in this embodiment, the sealing gasket 5 is an annular sealing gasket 5, which allows multiple through holes 20 to be located inside the annular sealing gasket 5. That is, when the annular sealing gasket 5 is squeezed, it can prevent the medium outside the diverter block 3 from entering through the gap between the diverter block 3 and the extension pipe 2. In addition, a sealing ring 6 is provided on the inner wall of the sleeve body 1 located at the through hole 20. When the fixing bolt 4 is threadedly connected to the diverter block 3 through the screw hole 30, the end of the fixing bolt 4 will squeeze the sealing ring 6, thereby filling the gap between the fixing bolt 4 and the through hole 20 and preventing the medium from entering the interior of the extension pipe 2 and causing leakage. It should also be noted that, since the environment in which the diverter block 3 is located is highly corrosive, in order to extend the service life of the gasket 5 and the sealing ring 6, they can be replaced with gasket 5 and sealing ring 6 made of corrosion-resistant material.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
