Description

TECHNICAL FIELD

[0001] The utility model relates to temperature detection technical field, concretely is a kind of automatic temperature measuring equipment of coking furnace carbonization chamber. BACKGROUND

[0002] In coke production, the temperature of coke oven needs to be measured, and the furnace temperature is controlled according to the measured data. The production process of coke is essentially a process of controlling the baking temperature and time of coke. Continuous and accurate measurement of the temperature of coke oven is the basis for ideal control of the temperature of coke oven, and is of great significance for improving coke quality, increasing coke production, reducing energy consumption and reducing environmental pollution.

[0003] There are two methods commonly used at present. One is a portable radiation temperature measuring instrument, which is operated manually, and measures one side of the furnace top every four hours, and controls the furnace temperature according to the measured data. The furnace cover is opened during measurement, and the operation is convenient. Because of the long temperature measurement interval, the time and position of temperature measurement will have a great impact on the temperature measurement data, especially in snow and rain weather, so this method is difficult to achieve ideal automatic control of the furnace temperature. The other is an infrared temperature measuring instrument installed on the top of the furnace for continuous temperature measurement. The infrared temperature measuring instrument is used to measure the combustion temperature inside the coke oven.

[0004] However, the coke oven often has a working environment of high temperature, dust, corrosion, toxicity, flammability and explosion. During the temperature detection process in the coke oven by the infrared temperature measuring instrument, the dust and flying sand in the coke oven will adhere to the lens of the infrared temperature measuring instrument, resulting in that the dust particles will adhere to the surface of the lens of the infrared temperature measuring instrument when the temperature inside the coke oven is detected again by the infrared temperature measuring instrument, forming a shielding layer, reducing the transmittance of infrared radiation, reducing the amount of infrared radiation received by the infrared temperature measuring instrument, and thus making the temperature measurement result low or inaccurate.

[0021] Please refer to Figs. 1-3 A coking furnace carbonization chamber automatic temperature measuring equipment, including the test column 1 that is arranged in the temperature measuring hole of coking furnace carbonization chamber, and the temperature measuring mechanism that is arranged in the test groove 14 of the end face of the test column 1, it is characterized in that, temperature measuring mechanism includes two mutually parallel mobile disc 17 that are arranged in test groove 14, control block 16 that is arranged between two mobile disc 17 and two ends are fixedly arranged in the center position of the adjacent end face of two mobile disc 17, control assembly that is arranged on test column 1 and can control two mobile disc 17 move to the outside of test groove 14, two infrared thermometers 18 that are symmetrically arranged about control block 16 and are located between two mobile disc 17, and cleaning assembly that is arranged on test column 1 and is arranged in two infrared thermometers 18 lens cleaning, two infrared thermometers 18 lens direction is far away from each other.

[0022] As Figs. 1-3As shown, the test column 1 is arranged in the temperature measuring hole, the control assembly drives the two moving discs 17 and the infrared temperature measuring instrument 18 to move into the coking chamber of the coking furnace to detect the temperature. At this time, the dust and flying sand in the coking chamber of the coking furnace will adhere to the lens of the infrared temperature measuring instrument 18. After the temperature test is completed, the control assembly drives the two moving discs 17 and the infrared temperature measuring instrument 18 to move into the test groove 14, and the cleaning assembly arranged on the test column 1 cleans the dust and flying sand on the lens of the infrared temperature measuring instrument 18, so as to ensure the cleanliness of the lens of the infrared temperature measuring instrument 18, facilitate the infrared temperature measuring instrument 18 to move into the coking chamber of the coking furnace again to detect the temperature again, avoid the dust particles adhering to the lens surface of the infrared temperature measuring instrument to form a shielding layer, reduce the transmittance of infrared radiation, cause the infrared radiation received by the infrared temperature measuring instrument to decrease, and thus cause the temperature measurement result to be low or inaccurate. The temperature can be conveniently detected, and the accuracy of the temperature detection is ensured.

[0023] The control assembly comprises a control screw 15 arranged in the test groove 14 along the axis direction of the test column 1, and a control motor 12 fixedly arranged on the end face of the test column 1 away from the test groove 14 and driving the control screw 15 to rotate. The control block 16 and the two moving discs 17 are threadedly connected to the control screw 15.

[0024] As shown in Fig. 2 The control motor 12 is a stepping motor. The control motor 12 drives the control screw 15 to rotate, thereby driving the two moving discs 17 and the control block 16 threadedly connected to the control screw 15 to move on the control screw 15, so as to facilitate the two moving discs 17 and the infrared temperature measuring instrument 18 to move into the coking chamber of the coking furnace.

[0025] The two moving discs 17 are limited to move in the test groove 14 along the length direction of the test column 1.

[0026] The following two modes can be adopted:

[0027] 1. A sliding rod penetrating the two moving discs 17 is arranged in the test groove 14 along the length direction parallel to the control screw 15. The two moving discs 17 are limited to move along the length direction of the sliding rod due to the limiting action of the sliding rod.

[0028] 2. Sliding blocks are fixedly arranged on the side surfaces of the two moving discs 17 and arranged in the sliding grooves. The sliding grooves are arranged in the groove walls of the test groove 14 along the axis length direction.

[0029] When the control motor 12 drives the control lead screw 15 to rotate, the moving disc 17 is movably sleeved on the sliding rod or the sliding block is slidably arranged in the sliding groove to limit the moving direction of the moving disc 17, so as to facilitate the movement of the moving disc 17 along the length direction of the control lead screw 15.

[0030] The opening position of the test groove 14 is provided with the sealing block 13, and the sealing block 13 is fixedly connected with the end face of the moving disc 17 through two fixed rods which are parallel to the control lead screw 15 and are arranged in the test groove 14.

[0031] The sealing block 13 arranged at the opening position of the test groove 14 avoids the dust and flying sand in the coking chamber from entering the test groove 14.

[0032] When the sealing block 13 is located at the opening position of the test groove 14, the side surface of the test column 1 located between the two moving discs 17 is provided with a cleaning hole which is communicated with the inside of the test groove 14, and the two cleaning holes are opposite to each other at the positions of the two infrared temperature measuring instruments 18. A cleaning assembly is arranged in the two cleaning holes and can clean the lenses of the two infrared temperature measuring instruments 18.

[0033] The cleaning assembly comprises a cleaning pipe 2 which is arranged in a vertical direction and has one end fixedly arranged at the opening position of the cleaning hole, a cleaning rod 23 which is transversely arranged in the cleaning pipe 2, a vertical rod 5 which is arranged in the cleaning pipe 2 in the axial direction of the cleaning pipe 2 and has a bottom end fixedly connected with the middle position of the top side surface of the cleaning rod 23, a lifting member which is arranged on the cleaning pipe 2 and can control the vertical rod 5 to move up and down in the vertical direction, and a cleaning motor 7 which is arranged on the lifting assembly and controls the vertical rod 5 to rotate. The cleaning rod 23 is provided with a cleaning brush 24 near the side surface of the test groove 14.

[0034] The vertical rod 5 is fixedly provided with a fan blade 22 on the rod body.

[0035] The lifting member comprises a support block 6 which is transversely arranged and has one end connected with the end of the vertical rod 5 away from the cleaning rod 23, a lifting lead screw 21 which is arranged at one side of the cleaning pipe 2 in parallel with the cleaning pipe 2 and has a top end connected with the side surface of the support block 6, a lifting motor 8 which is arranged on the support block 6 and controls the lifting lead screw 21 to rotate, a lifting rod 9 which is threadedly connected with the rod body of the lifting lead screw 21 and is sleeved on the rod body, and a buffer structure which is arranged on the end of the lifting rod 9 away from the lifting motor 8 and is connected with the side surface of the cleaning pipe 2. The cleaning motor 7 is arranged on the support block 6.

[0036] The buffer structure includes a first fixing block 10 fixedly installed on the bottom end of the lifting rod 9, a second fixing block 11 located on the side of the first fixing block 10 away from the lifting rod 9 and fixedly connected to the side of the cleaning tube 2, a telescopic rod 19 located between the first fixing block 10 and the second fixing block 11 and connected to the adjacent end faces of the first fixing block 10 and the second fixing block 11 respectively, and a limiting spring 20 movably sleeved on the telescopic rod 19. When the cleaning brush 24 is in contact with the lens of the infrared thermometer 18, the limiting spring 20 is in a stretched state.

[0037] like Figs. 2-3 As shown, after the infrared thermometer 18 moves into the test slot 14, the lifting motor 8 drives the lifting screw 21 to rotate, which in turn drives the lifting rod 9, which is threaded onto the lifting screw 21, to move in the direction of the lifting screw 21. This causes the support block 6 to move downwards, and the vertical rod 5 to move downwards. At this time, the cleaning brush on the bottom side of the cleaning rod 23 at the bottom end of the vertical rod 5 is in contact with the lens of the infrared thermometer 18. The cleaning motor 7 drives the vertical rod 5 to rotate, which in turn drives the cleaning rod 23 to rotate. The cleaning brush 24 on the cleaning rod 23 can then clean the dust and sand on the lens of the infrared thermometer 18. Simultaneously with the rotation of the vertical rod 5, the fan blades 22 on the vertical rod 5 move inwards. The rotating mechanism drives airflow, which in turn blows the dust cleaned from the lens of the infrared thermometer 18 into the test slot 14 between the two moving disks 17. The dust is then discharged through the inner tube of another cleaning pipe 2. When the control screw 15 moves the two moving disks 17 and the infrared thermometer 18 into the coking furnace carbonization chamber, the cleaning motor 7 drives the fan blades 22 and the cleaning rod 23 to rotate. This rotation of the cleaning rod 23 during the airflow process helps to shake off the dust and sand on the cleaning brush on the rod and discharge it into the test slot 14 through the airflow. This continuous cleaning of the lens of the infrared thermometer 18 facilitates convenient temperature detection and ensures the accuracy of temperature measurement.

[0038] When the two movable disks 17 are inserted into the test tank 14, a relatively closed space is formed between the two movable disks 17 and the tank wall of the test tank 14. When air enters through the inner tube of one of the cleaning pipes 2, it is easy to discharge the air from the test tank 14 through the inner tube of the other cleaning pipe 2.

[0039] The cleaning tube 2 has a sealing disc 4 that is movably sleeved on the vertical rod 5 at the end face opening position away from the test column 1, and the cleaning tube 2 has an air exchange pipe 3 that is internally connected to the inner tube of the cleaning tube 2.

[0040] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
