[0003] Therefore, how to prevent the chlorination furnace thermometer from being broken during installation or maintenance has become a problem to be solved by researchers in the field. UTILITY MODEL CONTENT

[0004] The utility model wants to solve the technical problem that how to prevent the chlorination furnace thermometer from being broken during installation or maintenance.

[0005] To solve the above technical problem, the utility model adopts the technical scheme that

[0006] The utility model relates to a chlorination furnace thermometer, which comprises a first corundum sleeve, a first stainless steel sleeve, a temperature measuring element and a connecting flange.

[0007] In the scheme, the connecting flange is used to connect the thermometer and the furnace body, the first stainless steel sleeve is covered outside the first corundum sleeve, the first corundum sleeve is protected from being bent due to the rigidity of the first stainless steel sleeve, and in addition, the first stainless steel sleeve has small thermal resistance, so that the first stainless steel sleeve added outside the first corundum sleeve does not affect the detection value of the temperature measuring element.

[0008] In order to further increase the strength of the first corundum sleeve, the utility model adopts the first corundum sleeve provided with a second stainless steel sleeve.

[0009] In this way, the first corundum sleeve is arranged between the first stainless steel sleeve and the second stainless steel sleeve, so that the first corundum sleeve is less likely to be broken.

[0010] In order to increase the service life of the thermometer, the utility model adopts the second stainless steel sleeve provided with a second corundum sleeve, and the temperature measuring element is located in the second corundum sleeve.

[0011] In use, the gas of the chlorination furnace can corrode the stainless steel sleeve and the corundum sleeve, and solid particles can impact the stainless steel sleeve and the corundum sleeve, so that the stainless steel sleeve and the corundum sleeve are continuously corroded; the second corundum sleeve is arranged in the second stainless steel sleeve, so that the service life is prolonged and the replacement frequency of the thermometer is reduced.

[0012] In order to illustrate the material of the first stainless steel sleeve and the second stainless steel sleeve, the first stainless steel sleeve and the second stainless steel sleeve are made of 316 stainless steel.

[0013] The first stainless steel sleeve and the second stainless steel sleeve made of 316 stainless steel can reduce the gas corrosion of the chlorination furnace, slow down the corrosion, and reduce the replacement frequency of the thermometer.

[0014] The temperature agent in the scheme is replaced only after half a year to one year in actual use, so that the replacement frequency is reduced and the use cost is reduced compared with the replacement frequency of about one month of the traditional thermometer.

[0015] The utility model discloses the beneficial effects: the utility model relates to a chlorination furnace thermometer, and the connecting flange is used for connecting the thermometer with the furnace body, and the first stainless steel sleeve is covered outside the first corundum sleeve, and the first corundum sleeve is protected from bending due to the rigidity of the first stainless steel sleeve, and in addition, the first stainless steel sleeve has small thermal resistance, so that the detection value of the temperature measuring element is not affected by the first corundum sleeve, and the thermometer of the chlorination furnace is not broken during installation or maintenance. BRIEF DESCRIPTION OF DRAWINGS

[0016] The utility model is further illustrated below in connection with the drawings and examples.

[0017] Figure 1 It is the structural schematic diagram of the utility model;

[0018] Figure 2 It is Figure 1 A enlarged view of the place of the first corundum sleeve;

[0019] In the drawing: 1-first corundum sleeve, 2-first stainless steel sleeve, 3-temperature measuring element, 4-connecting flange, 5-second stainless steel sleeve, 6-second corundum sleeve. DETAILED DESCRIPTION

[0020] The utility model will be further explained in detail in connection with the drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the utility model in a schematic manner, so that it only shows the structure related to the utility model.

[0021] For example, Figures 1-2As shown, the utility model is a kind of chlorination furnace thermometer, comprising: first corundum cover 1;First stainless steel cover 2, it is covered in first corundum cover 1 outside;Temperature measuring element 3, it enters from the top opening of first corundum cover 1, and its end is placed in first corundum cover 1;Connecting flange 4, it is arranged in first stainless steel cover 2 outside;

[0022] In the present scheme, connecting flange is used to connect thermometer with furnace body, first stainless steel cover is covered outside first corundum cover, due to the rigidity of first stainless cylinder cover, protect first corundum cover from bending, in addition, due to the smaller thermal resistance of first stainless cylinder cover, the detection value of temperature measuring element will not be affected by the first stainless steel cover outside first corundum cover;

[0023] As shown in the figure, Figures 1-2 In order to further increase the strength of first corundum cover, the utility model adopts the second stainless steel cover 5 arranged in the first corundum cover 1.

[0024] The first stainless steel cover and the second stainless steel cover are arranged with the first corundum cover, so that the first corundum cover is less likely to break.

[0025] As shown in the figure, Figures 1-2 In order to increase the service life of thermometer, the utility model adopts the second corundum cover 6 arranged in the second stainless steel cover 5, and the temperature measuring element 3 is located in the second corundum cover 6.

[0026] In use, the gas of chlorination furnace can corrode the stainless steel cover and the corundum cover, and solid particles can impact the stainless steel cover and the corundum cover, causing the stainless steel cover and the corundum cover to be continuously corroded. The second corundum cover is arranged in the second stainless steel cover, which increases the service life and reduces the replacement frequency of thermometer.

[0027] The bottom of the second corundum cover, the first corundum cover, the first stainless steel cover and the second stainless steel cover is closed, and the top is open.

[0028] As shown in the figure, Figures 1-2 In order to explain the material of first stainless steel cover and second stainless steel cover, the utility model adopts the material of first stainless steel cover 2 and second stainless steel cover 5, which is 316 stainless steel.

[0029] The first stainless steel cover and the second stainless steel cover of 316 stainless steel can reduce the gas corrosion of chlorination furnace, slow down the corrosion and reduce the replacement frequency of thermometer.

[0030] In actual use, the temperature agent in the present scheme is replaced every half year to one year, which reduces the replacement frequency and use cost compared with the traditional replacement frequency of about one month.
