[0012] Preferably, the moisture detection structure includes a microwave moisture meter, and two microwave moisture meters are provided. The two microwave moisture meters are respectively installed through the upper surface of the first branch pipe and the second branch pipe. The probe of the microwave moisture meter is inserted into the interior of the first branch pipe and the second branch pipe. A reinforcing block is fixedly installed on the outer surface of the microwave moisture meter and the reinforcing block is fixedly installed on the upper surface of the first branch pipe and the second branch pipe.
[0013] By adopting the above technical solution, the stability of the microwave moisture meter installation can be increased by using reinforcement blocks.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the moisture detection device for the material conveying system: 1. In this device, a material conveying pipeline is connected through a main conveying pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-6 This utility model provides a technical solution: a moisture detection device for a material conveying system, including a conveying main pipe 1, a first branch pipe 2, a first connecting pipe 3, a second branch pipe 4, a second connecting pipe 5, a microwave moisture meter 6, a reinforcing block 7, a guide plate 8, a first valve 9, and a second valve 10.
[0023] The main conveying pipe 1 is for conveying materials. Two branch pipes 2 and 4 are symmetrically arranged on both sides of the main conveying pipe 1. Microwave moisture meters 6 are installed inside the branch pipes 2 and 4 respectively. Two connecting pipes 3 are fixedly connected to both ends of the branch pipe 2. The other ends of the two connecting pipes 3 penetrate the side surface of the main conveying pipe 1. A valve 9 is installed inside each of the two connecting pipes 3. Two connecting pipes 5 are fixedly connected to both ends of the branch pipe 4. The other ends of the two connecting pipes 5 penetrate the side surface of the main conveying pipe 1. A valve 9 is installed inside each of the two connecting pipes 5. A second valve 10 is provided, and a moisture detection structure is provided inside the first branch pipe 2 and the second branch pipe 4. The moisture detection structure can detect the moisture of the material through a microwave moisture meter 6. The moisture detection structure includes a microwave moisture meter 6, and two microwave moisture meters 6 are provided. The two microwave moisture meters 6 are respectively installed through the upper surface of the first branch pipe 2 and the second branch pipe 4. The probe of the microwave moisture meter 6 is inserted into the interior of the first branch pipe 2 and the second branch pipe 4. A reinforcing block 7 is fixedly installed on the outer surface of the microwave moisture meter 6. The reinforcing block 7 is fixedly installed on the upper surface of the first branch pipe 2 and the second branch pipe 4. like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, during use, both ends of the main conveying pipe 1 are connected and fixed to the pulp material conveying pipe, so that the device is connected to the pulp material conveying system. At this time, valve 9 in the first connecting pipe 3 and valve 10 in the second connecting pipe 5 are both closed. At this time, the material is only conveyed normally along the main conveying pipe 1. There is no material flow in the first branch pipe 2 and the second branch pipe 4. The microwave moisture meter 6 is in standby mode. The probe of the microwave moisture meter 6 is fixed to the upper surface of the first branch pipe 2 and the second branch pipe 4 by the reinforcing block 7. When it is necessary to detect the moisture content of the material, the opening and closing of valve 9 and valve 10 can be controlled as needed. The following situations exist: When valve 9 is opened and valve 10 is closed, branch pipe 2 is connected to main conveyor pipe 1. The material in main conveyor pipe 1 will be diverted to branch pipe 2 through connecting pipe 3. Microwave moisture meter 6 at branch pipe 2 is started and the moisture of the material is detected. At this time, there is no material flow in branch pipe 4, and branch pipe 4 and microwave moisture meter 6 at this location can be maintained. When valve 9 is closed and valve 10 is opened, the second branch pipe 4 is connected to the main conveying pipe 1. The material in the main conveying pipe 1 enters the second branch pipe 4 and is tested for moisture by microwave moisture meter 6. At this time, there is no material flow inside the first branch pipe 2, and the first branch pipe 2 and the microwave moisture meter 6 can be maintained. Valve 9 and valve 10 are opened simultaneously, and the material flows into branch pipe 2 and branch pipe 4 respectively through connecting pipe 3 and connecting pipe 5. Two microwave moisture meters 6 are started simultaneously to detect the moisture content of the material in branch pipe 2 and branch pipe 4 respectively. By comparing the detection data of the two microwave moisture meters 6, the error that may occur from a single detection can be eliminated, and the accuracy of the detection results can be improved.
[0024] The first branch pipe 2 and the second branch pipe 4 are equipped with a flow guiding and anti-impact structure. The flow guiding and anti-impact structure protects the probe of the microwave moisture meter 6 through the flow guiding plate 8. The flow guiding and anti-impact structure includes the flow guiding plate 8, which is arc-shaped and is fixedly installed on the inner wall of the first branch pipe 2. Two flow guiding plates 8 are symmetrically arranged on the inner wall of the first branch pipe 2. The two flow guiding plates 8 are symmetrically arranged with the probe of the microwave moisture meter 6 as the axis. There are two sets of flow guiding plates 8. Another set of flow guiding plates 8 is arranged on both sides of the microwave moisture meter 6 inside the second branch pipe 4. like Figure 1 , Figure 5 and Figure 6 As shown, when the material enters the first branch pipe 2 and the second branch pipe 4 during the conveying process, the material will be guided by the guide plates 8 symmetrically arranged on the inner wall. The guide plates 8 are symmetrically distributed around the probe of the microwave moisture meter 6 and have an arc-shaped structure, which allows the high-speed flowing material to flow along the inner wall of the branch pipe, avoiding direct impact on the probe of the microwave moisture meter 6, reducing probe wear, and thus increasing the service life of the microwave moisture meter 6.
[0025] Working Principle: When using the moisture detection device of this material conveying system, connect both ends of the conveying main pipe 1 to the material conveying pipeline. In the initial state, valve 9 in connecting pipe 3 and valve 10 in connecting pipe 5 are both closed. The material is conveyed normally only along the conveying main pipe 1, and the microwave moisture meter 6 is on standby. When moisture detection of the material is required, valves 9 and 10 can be controlled as needed. Opening valve 9 alone allows the material to flow into branch pipe 2 through connecting pipe 3, and the corresponding microwave moisture meter 6 is activated for detection. Branch pipe 4 can be maintained simultaneously. Opening valve 10 alone allows the material to flow into branch pipe 4, and the corresponding microwave moisture meter 6 is activated for detection. Branch pipe 2 can be maintained simultaneously. Opening valves 9 and 10 simultaneously allows the microwave moisture meters 6 on both sides to detect simultaneously, and the detection accuracy is improved by comparing the data. The arc-shaped guide plate 8 is symmetrically distributed around the probe of the microwave moisture meter 6, guiding the material to flow along the inner wall of the branch pipe, avoiding impact on the probe, extending the equipment life, and increasing the overall practicality.
