Description

Technical Field

[0001] The present invention belongs to the technical field of heat exchange tube replacement, and in particular relates to an intelligent material storage warehouse and a work control method based on tube roundness recognition. Background Art

[0002] Heat exchange tubes are a crucial component of shell-and-tube heat exchangers. They possess high thermal conductivity and excellent isothermal properties. They are devices that rapidly transfer heat from one point to another. They are secured to the interior of the heat exchanger via baffles.

[0003] The traditional method of tube insertion is manual. Specifically, the baffles are equipped with multiple insertion holes, spaced at regular intervals. Workers must sequentially insert the heat exchange tubes through these holes. Since heat exchange tube lengths typically range from 3 to 9 meters, and large shell-and-tube heat exchangers can reach up to 9 meters in length, multiple workers are required to lift and insert the heat exchange tubes into the baffles. Furthermore, since heat exchangers can reach heights of up to 3 meters, manual insertion often requires the use of a lifting device to insert the tubes into the baffles. A single heat exchanger often requires hundreds or even thousands of tubes. The traditional manual tube insertion method creates a significant workload and places significant demands on the warehouses used to store them. Furthermore, during the current manual tube insertion process, human visual identification is used to eliminate tubes with excessively large roundness, as this factor directly impacts the difficulty of insertion. However, this can be subject to significant errors, and some tubes can be up to 9 meters long, making the visual identification process even more challenging.

[0004] It can be seen that in order to cooperate with the design and operation of the automatic intubation machine, it is urgent to design an intelligent storage warehouse with the function of identifying and screening the roundness of pipe materials. Summary of the Invention

When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may also be a central component.

[0036] Example 1:

[0037] like Figure 1-2 As shown, the first embodiment provides an intelligent material storage warehouse based on pipe roundness recognition, the material storage warehouse includes a steel structure frame; a material storage bin arranged on the upper part of the steel structure frame, and a first-level slide, a second-level slide, a third-level slide, and a fourth-level slide arranged inside the steel structure frame and at the bottom of the material storage bin in sequence;

[0038] Among them, the storage bin is used to store multiple heat exchange tubes, and the storage bin has an opening, which can only pass one heat exchange tube at a time; the entrance of the first-level slide corresponds to the opening of the storage bin; and the first-level slide, the second-level slide, the third-level slide and the fourth-level slide are each provided with an exit between two adjacent slides, and the position of each exit is set at one end away from each other; the second-level slide is an openable and closable gate structure, and the gate structure is connected to a control switch, and a camera is also provided on the secondary slide, and the camera is used to obtain image information of the heat exchange tube located on the secondary slide; a control component electrically connected to the control switch and the camera; wherein, the control component is used to obtain image information of the heat exchange tube, and judge whether the roundness value of the heat exchange tube meets the preset roundness value based on the image information. If not, the control switch is controlled to open the gate structure.

[0039] Specifically, the present invention proposes an intelligent storage warehouse based on pipe roundness identification. A roundness identification device is set on the second-level slide to identify whether the heat exchange tube sliding into the second-level slide meets the roundness requirements. If it meets the requirements, the heat exchange tube that meets the roundness requirements continues to be transported. If it does not meet the requirements, it is automatically recovered. Specifically, it includes a storage bin and a first-level slide, a second-level slide, a third-level slide and a fourth-level slide arranged in a steel structure frame, and a roundness identification device, that is, a camera, is set on the second-level slide. The camera is electrically connected to the control component. When the heat exchange tube slides onto the second-level slide, the camera obtains image information of the heat exchange tube and sends the image information to the control component. The control component determines whether the heat exchange tube meets the preset roundness requirements through the image information. If it meets the requirements, the heat exchange tube enters the third-level slide. If it does not meet the requirements, the control switch is controlled to open, the gate is opened, and the heat exchange tube that does not meet the preset roundness requirements is recovered, thereby improving the technical purpose of identifying the roundness of the heat exchange tube and achieving the technical effect of solving the problem of difficulty in manual identification.

[0040] In the first aspect, the storage warehouse further includes a push rod; the push rod is arranged at the end of the second-level slide away from the non-opening, and the push rod is electrically connected to the control component for receiving instructions from the control component to perform telescopic movements.

[0041] This is because, in order to improve the sliding efficiency of the heat exchange tube in the second-stage slide, the push rod is used to assist the heat exchange tube to quickly slide into the outlet of the second-stage slide.

[0042] In the first aspect, the second-level slide includes a horizontal part and an inclined part; the horizontal part is located on the side close to the push rod, and the inclined part is connected to the end of the horizontal part away from the push rod to extend the inclined direction to the opening direction of the second-level slide, and the camera is set in the horizontal part.

[0043] By providing a horizontal portion so that the heat exchange tube stays at the horizontal portion, the camera in the above embodiment can accurately obtain image information of the heat exchange tube. After obtaining the information, the heat exchange tube on the horizontal portion is pushed to the inclined portion by the push rod, and then the inclined portion causes the heat exchange tube to slide to the outlet of the second-stage slide.

[0044] In the first aspect, the surfaces of the first-level slide, the second-level slide, the third-level slide and the fourth-level slide are all provided with a protective layer, which includes a rubber coating coated on the outer surfaces of the first-level slide, the second-level slide, the third-level slide and the fourth-level slide.

[0045] Since the first-stage slide, the second-stage slide, the third-stage slide and the fourth-stage slide are all composed of steel structures, in order to prevent the heat exchange tubes from being damaged when they come into contact with the first-stage slide, the second-stage slide, the third-stage slide and the fourth-stage slide, a protective layer is provided on the surface of the first-stage slide, the second-stage slide, the third-stage slide and the fourth-stage slide, and embodiment 1 of the present invention preferably uses a rubber coating as the protective layer.

[0046] In the first aspect, a resistance material is provided on the horizontal portion.

[0047] This can prevent the friction between the horizontal portion and the heat exchange tube from increasing, thereby preventing the heat exchange tube from sliding when located at the horizontal portion.

[0048] In the first aspect, the material storage warehouse further includes a waste bin; the waste bin is arranged in the steel structure frame and is located at the bottom of the gate.

[0049] When heat exchange tubes that do not meet the preset roundness are found, they can be recycled through the waste bin.

[0050] In the first aspect, an infrared sensor is further provided in the waste bin; the infrared sensor is connected to the control component.

[0051] This is to use infrared sensors to detect in real time the number of heat exchange tubes in the waste bin that do not meet the roundness requirements, so that the detected number can be sent to the control component in real time.

[0052] In the first aspect, counters are provided on the second-stage slide and the third-stage slide; the storage bin further comprises an alarm assembly, and the alarm assembly, the counter and the control assembly are electrically connected.

[0053] In the above-mentioned embodiment 1, the purpose of setting counters on the second-stage slide and the third-stage slide is to count the number of heat exchange tubes located on the second-stage slide and the third-stage slide in real time. When the number of the second-stage slide and the third-stage slide reaches a preset value, the control component sends an alarm instruction to the alarm component to provide a warning to the staff to stop the input of the heat exchange tubes in the third-stage slide and the fourth-stage slide.

[0054] Example 2:

[0055] like Figure 3-4 As shown, the present invention provides a working control method of an intelligent storage warehouse based on pipe roundness recognition, and the intelligent storage warehouse based on pipe roundness recognition includes: a storage warehouse, a first-level slide, a second-level slide, a third-level slide, a fourth-level slide, a camera and a control component; the storage warehouse is used to store multiple heat exchange tubes, and the storage warehouse has an opening, and the opening can only pass one heat exchange tube at a time; the second-level slide is an openable and closable gate structure, and the gate structure is connected to a control switch, and a camera is also provided on the secondary slide, and the control switch, camera and control The components are electrically connected, and the working control method includes: making the heat exchange tube slide from the opening of the storage bin to the first-stage slide, and sliding from the opening of the first-stage slide to the second-stage slide; when the heat exchange tube slides to the second-stage slide, the controller controls the camera to obtain image information of the heat exchange tube, and judges whether the roundness value of the heat exchange tube meets the preset roundness value based on the image information. If not, the control switch is controlled to open the gate structure; if so, the push rod is controlled to perform a telescopic action to push the heat exchange tube to the third-stage slide, so that it slides from the third-stage slide into the fourth-stage slide.

[0056] In the above scheme, servos and railings are installed at the tail ends of the first-level slide, the second-level slide, and the third-level slide. There is a counter above to count the pipes entering the second-level slide and the third-level slide. When the counter shows that the number of pipes entering the third-level slide reaches a certain number, and the warehouse as a whole is not in the material-retrieving state, the servo at the end of the second-level slide is lifted to prevent the pipes from entering the third-level slide. Thereafter, if the number of pipes in the second-level slide reaches a certain number, the servo at the exit of the first-level slide will be activated to close the exit of the first-level slide. When the warehouse as a whole is in the pipe-retrieving state, there are about three servo channels, and the pipes slide to the lower-level pipeline, and then the above actions are repeated. A control cabinet and a touch screen for control are placed in the lower part of the storage warehouse to display the warehouse inventory and working status.

[0057] In the second aspect, counters are provided on the second-stage slide and the third-stage slide; the storage bin also includes an alarm component, and the alarm component, the counter and the control component are electrically connected. The control method includes: controlling the counter through the control device to obtain the number of heat exchange tubes on the second-stage slide and the third-stage slide; if the number of heat exchange rods on the second-stage slide or the third-stage slide reaches a preset number, the control component controls the alarm component to sound an alarm.
