Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco equipment, and in particular relates to an online detection device for rotary joints of drying drum equipment. Background Art

[0002] The rotary joint of the tobacco drying machine is the only channel for the steam to enter and exit the cylinder of the tobacco drying machine, and the steam in the cylinder plays a leading role in the dehydration of tobacco, thereby improving and enhancing the sensory quality of tobacco leaves. Whether the rotary joint works stably and reliably is crucial to the steam pressure and flow control of the tobacco drying machine.

[0003] At present, when there is a fault of large fluctuations in moisture at the outlet of the tofu drying machine, whether the rotary joint is working properly is usually included in the cause of the fault for investigation. The inspection method is to disassemble the rotary joint and check whether the rotary joint seal is severely worn, causing the steam inlet channel and the steam outlet channel to be connected, resulting in steam instability.

[0004] If the inspection result shows that the rotary joint is not faulty, other reasons will be checked. However, the rotary joint weighs hundreds of kilograms and is located high up in the dryer, making installation and disassembly operations very complicated, which in turn leads to low maintenance efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide an online detection device for the rotary joint of a drying drum type equipment. Through the cooperation of a steam flow meter and two pressure sensors, the steam flow of the rotary joint, the steam pressure in the steam inlet channel, and the steam pressure in the steam outlet channel are measured when a fault occurs in which the moisture content at the outlet of the drying machine fluctuates greatly. The working state of the rotary joint is judged without disassembling the rotary joint, which makes detection more convenient and improves maintenance efficiency.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] An online detection device for rotary joints of drying drum equipment, comprising:

[0008] A steam flow meter, which is installed on the steam inlet passage of the rotary joint and is used to detect the flow rate of steam entering the rotary joint;

[0009] Two pressure sensors, which are respectively installed in the steam inlet channel and the steam outlet channel of the rotary joint, and are used to detect the pressure of the steam inlet channel and the pressure of the steam outlet channel of the rotary joint respectively;

[0010] A data processor is connected to the steam flow meter and two pressure sensor signals for data collection and storage.

[0011] It is further defined that the pressure sensor is equipped with a female seat that passes through the steam inlet channel / steam outlet channel, and a quick-plug connector is detachably installed on the female seat, and the pressure sensor is connected to the data processor signal through the female seat and the quick-plug connector. Such a structural design completes the signal connection between the pressure sensor and the data processor through the detachable connection between the quick-plug connector and the female seat, and utilizes its detachable characteristics to disconnect the signal connection between the pressure sensor and the data processor when no detection is performed, thereby avoiding the problem of cluttered lines, and is highly practical.

[0012] It is further defined that the outer wall of the female seat is provided with an external thread, the quick-plug connector is sleeved with a connecting tube with an internal thread, the inner wall of the connecting tube away from the female seat is fixed with a limiting ring, and the outer wall of the quick-plug connector is fixed with a fixing ring;

[0013] When the connecting tube is threadedly connected to the female seat, the limiting ring presses the fixing ring onto the end surface of the female seat.

[0014] This structural design, through the threaded connection between the connecting tube and the female seat, cooperates with the limit ring and the fixing ring, further strengthens the connection stability between the quick-connect connector and the female seat, and is highly practical.

[0015] It is further defined that the female base is detachably provided with an end cap. With such a structural design, when the quick-connect connector is disconnected from the female base without detection, the female base can be sealed with the end cap to prevent external dust and water vapor from affecting the signal connection mechanism in the female base, which is highly practical.

[0016] It is further defined that the end cover is threadedly connected to the female seat.

[0017] It is further defined that a connecting belt is installed between the end cap and the mother seat. Such a structural design connects the end cap and the mother seat through the connecting belt, so that when the end cap is not installed on the mother seat, it is connected by the connecting belt, so that it will not be placed anywhere, thereby causing the problem of being unable to find it when it is needed.

[0018] The utility model adopting the above technical solution has the following advantages:

[0019] 1. Through the cooperation of the steam flow meter and two pressure sensors, the steam flow of the rotary joint, the steam pressure in the steam inlet channel, and the steam pressure in the steam outlet channel are measured when there is a fault of large fluctuation of moisture at the outlet of the tofu drying machine, and the working state of the rotary joint is judged. There is no need to disassemble the rotary joint, which makes the detection more convenient and improves the maintenance efficiency;

[0020] 2. Through the detachable connection of the quick-plug connector and the female socket, the signal connection between the pressure sensor and the data processor is completed. At the same time, by utilizing its detachable characteristics, the signal connection between the pressure sensor and the data processor can be disconnected when no detection is performed, avoiding the problem of cluttered lines, and the practicability is strong.

In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.

[0026] like Figure 1 As shown, the utility model is an online detection device for rotary joints of drying drum equipment, comprising:

[0027] Steam flow meter, which is installed on the steam inlet channel of the rotary joint and is used to detect the flow rate of steam entering the rotary joint;

[0028] Two pressure sensors 1, the two pressure sensors 1 are respectively installed in the steam inlet channel and the steam outlet channel of the rotary joint, and are used to detect the pressure of the steam inlet channel and the pressure of the steam outlet channel of the rotary joint respectively;

[0029] The data processor is connected with the steam flow meter and two pressure sensors 1 for data collection and storage.

[0030] The pressure sensor 1 is provided with a female base 2 passing through the steam inlet channel / steam outlet channel, and a quick-connect connector 3 is detachably installed on the female base 2. The pressure sensor 1 is connected to the data processor signal through the female base 2 and the quick-connect connector 3. In fact, according to the actual situation, the pressure sensor 1 and the data processor can be directly connected by wires. This embodiment completes the signal connection between the pressure sensor 1 and the data processor through the detachable connection between the quick-connect connector 3 and the female base 2. At the same time, the signal connection between the pressure sensor 1 and the data processor can be disconnected by utilizing its detachable characteristics when no detection is performed, thereby avoiding the problem of cluttered lines, and having strong practicality.

[0031] The outer wall of the female seat 2 is provided with an external thread, and the quick-insert connector 3 is sleeved with a connecting tube 4 with an internal thread, and the inner wall of the connecting tube 4 away from the end of the female seat 2 is fixed with a limiting ring, and the outer wall of the quick-insert connector 3 is fixed with a fixing ring;

[0032] When the connecting tube 4 is screwed onto the female seat 2 , the limiting ring squeezes the fixing ring onto the end surface of the female seat 2 .

[0033] By threading the connecting tube 4 and the female seat 2, in combination with a limiting ring and a fixing ring, the connection stability between the quick-connect connector 3 and the female seat 2 is further strengthened, and the practicality is strong.

[0034] The female base 2 is detachably provided with an end cap 6. By setting the end cap 6, when no detection is performed and the quick-plug connector 3 is disconnected from the female base 2, the female base 2 can be sealed by the end cap 6 to prevent external dust and water vapor from affecting the signal connection mechanism in the female base 2, which is highly practical.

[0035] The end cover 6 is screwed to the female seat 2 .

[0036] A connecting belt 5 is installed between the end cap 6 and the female base 2. The end cap 6 is connected to the female base 2 by the connecting belt 5, so that when the end cap 6 is not installed on the female base 2, it is connected by the connecting belt 5, so as not to be placed anywhere, thereby causing the problem of not being able to find it when it is needed.

[0037] In this embodiment, when a failure occurs in which the moisture content at the outlet of the tofu drying machine fluctuates greatly, the end cover 6 is removed, the quick-connect connector 3 is inserted into the female seat 2, and the connecting tube 4 is tightened to complete the signal connection of the two pressure sensors 1 of the data processor;

[0038] The data processor receives the steam flow rate of the rotary joint, the steam pressure in the steam inlet channel, and the steam pressure in the steam outlet channel at this time, and then compares these values ​​with the fault data in the database to judge the working status of the rotary joint and determine whether the rotary joint has a fault.
