Description

Technical Field

[0001] This utility model relates to the field of fluidized bed technology, specifically to an automatic telescopic control mechanism for an online moisture detection probe in a fluidized bed. Background Technology

[0002] A fluidized bed is a reactor that uses gas or liquid to pass through a layer of particulate solids, suspending the solid particles and allowing gas-solid or liquid-solid phase reactions to occur. This technology has wide applications in many fields, including chemical reactions, solid separation, fluidized bed catalytic cracking, fluidized bed combustion, and heat and mass transfer.

[0003] Currently, when testing the moisture content of materials dried in a fluidized bed, if a rapid moisture analyzer is used after sampling, the testing time is about 5 minutes, which is time-consuming and cannot guarantee that the moisture content of the sampled material meets the production process requirements.

[0004] If microwave online moisture detection is used, the moisture content of the dried material can be displayed online. However, since the material is relatively damp when it first starts drying, it is easy to stick to the surface of the moisture detection probe, resulting in inaccurate moisture detection. Utility Model Content

[0005] The purpose of this invention is to provide an automatic telescopic control mechanism for an online moisture detection probe in a fluidized bed, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic telescopic control mechanism for an online moisture detection probe in a fluidized bed, comprising a fluidized bed body, wherein a microwave online moisture detection probe penetrating the fluidized bed body is disposed at a lower outer position of the fluidized bed body, and the length of the microwave online moisture detection probe extending into the fluidized bed body can be adjusted by an adjustment mechanism.

[0007] Preferably, the central axis of the microwave online moisture detection probe is perpendicular to the projection line of the left inner wall of the fluidized bed body.

[0008] Preferably, the adjustment mechanism includes two telescopic cylinders symmetrically arranged on both sides of the microwave online moisture detection probe. One end of the telescopic cylinder is detachably and fixedly installed on the surface of the fluidized bed body, and the other end of the telescopic cylinder is fixedly connected to a connecting plate, which is fixedly installed on the outer surface of the microwave online moisture detection probe.

[0009] Preferably, the telescopic cylinder is detachably and fixedly mounted on the surface of the fluidized bed body by bolts.

[0010] Preferably, the outer surface of the telescopic cylinder is detachably fitted with a protective shell, and the protective shell is provided with a connector for signal connection with the telescopic cylinder.

[0011] Preferably, the connector can be electrically connected to the PLC controller via a wire, thereby controlling the telescopic cylinder to extend and retract at different time periods.

[0012] Beneficial effects

[0013] This utility model provides an automatic telescopic control mechanism for an online moisture detection probe in a fluidized bed, which has the following advantages:

[0014] The automatic telescopic control mechanism for the online moisture detection probe in this fluidized bed allows the probe to be retracted from the fluidized bed before the material dries, preventing contact with damp material. After the material has dried for a period of time, the probe can be re-inserted into the fluidized bed for online moisture detection, ensuring accurate results. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-2This utility model provides a technical solution: an automatic telescopic control mechanism for an online moisture detection probe in a fluidized bed, comprising a fluidized bed body 1, with a microwave online moisture detection probe 2 penetrating the fluidized bed body 1 located on the lower outer side of the fluidized bed body 1. The length of the microwave online moisture detection probe 2 extending into the fluidized bed body 1 can be adjusted by an adjustment mechanism 3. By setting the adjustment mechanism 3, the microwave online moisture detection probe 2 can be withdrawn from the fluidized bed body 1 before the material inside the fluidized bed body 1 dries, avoiding contact with the damp material. After the material has dried for a period of time, the microwave online moisture detection probe 2 can be extended back into the fluidized bed body 1 using the adjustment mechanism 3, thereby enabling online detection of the material moisture and ensuring the accuracy of the detection results.

[0020] The central axis of the microwave online moisture detection probe 2 is perpendicular to the projection line of the left inner wall of the fluidized bed body 1. This setting allows the microwave online moisture detection probe 2 to be removed from the fluidized bed body 1, minimizing contact with the material.

[0021] The adjustment mechanism 3 includes two telescopic cylinders 4 symmetrically arranged on both sides of the microwave online moisture detection probe 2. One end of the telescopic cylinder 4 is detachably and fixedly installed on the surface of the fluidized bed body 1, and the other end of the telescopic cylinder 4 is fixedly connected to a connecting plate 5. The connecting plate 5 is fixedly installed on the outer surface of the microwave online moisture detection probe 2. By setting the telescopic cylinder 4 and the connecting plate 5, the telescopic cylinder 4 can drive the connecting plate 5 to move, thereby driving the microwave online moisture detection probe 2 to extend into or out of the fluidized bed body 1.

[0022] The telescopic cylinder 4 is detachably and fixedly installed on the surface of the fluidized bed body 1 by bolts. This setting facilitates the subsequent maintenance and repair of the telescopic cylinder 4.

[0023] The outer surface of the telescopic cylinder 4 is detachably fitted with a protective shell 6, and the protective shell 6 is provided with a connector 7 for signal connection with the telescopic cylinder 4. By providing the protective shell 6, the telescopic cylinder 4 can be protected.

[0024] The connector 7 can be electrically connected to the PLC controller via a wire, thereby controlling the telescopic cylinder 4 to extend and retract at different time periods. By setting the connector 7, the PLC controller can easily control the telescopic cylinder 4. By controlling the telescopic cylinder 4 to extend and retract at different time periods, the moisture content of the material at different time periods can be measured.
