Description

Technical Field

[0001] The invention relates to the field of sludge dryers and particularly discloses an intelligent control system for the dryer. Background Art

[0002] Sludge dryers are used for urban domestic and industrial sludge treatment. They can dry wet sludge into dry sludge with less water content. The dried sludge has a higher content of combustible matter, so the sludge can be used for incineration to generate electricity.

[0003] Existing sludge dryers generally include a body, a feed port, a discharge port, and a hollow shaft. The feed port and discharge port are both located on the body, while the hollow shaft is located inside the body. The hollow shaft is hollow and can be passed through high-temperature steam. The high-temperature steam heats the hollow shaft, which in turn heats and dries the sludge, thereby drying the sludge. Existing sludge dryers have several disadvantages: 1. The drying effect is affected by factors such as the sludge moisture content, the sludge feed amount, the steam pressure within the hollow shaft, and the discharge amount. Adjusting the drying effect is generally done by adjusting the baffle at the sludge discharge port. This method is relatively simple, but since the baffle is generally operated manually, it increases labor intensity and may result in personal injury. 2. After the hollow shaft has been operating for a long time, a large amount of sludge will be contaminated on its outer wall, resulting in a poor drying effect. Summary of the Invention

[0004] In view of this, the object of the present invention is to provide an intelligent control system for a dryer to solve the technical problem of how to automatically control the sludge feed inlet baffle to adjust the sludge drying effect.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A dryer intelligent control system includes a dryer body, a hollow shaft, a feed port and a discharge port, the feed port and the discharge port are respectively arranged on both sides of the dryer body, the hollow shaft is rotatably arranged in the dryer body, the dryer body is provided with a plurality of observation windows, the upper end of the inner wall of the dryer body is provided with a plurality of detection probe units, each detection probe unit is aligned with an observation window, the detection probe unit includes a mounting seat, a probe seat and a plurality of probe bodies, the mounting seat is fixedly provided on the inner wall of the dryer body, the probe seat is detachably provided on the mounting seat, the probe bodies are all provided on the probe seat, and the plurality of probe bodies have temperature detection functions, a baffle is vertically slidably provided on the discharge port, an electric adjustment cylinder is provided on the outer wall of the dryer body, the lower end of the baffle extends to the bottom of the dryer body and is connected to the output end of the electric adjustment cylinder. In this solution, a detection probe unit is provided in the dryer body. The detection probe unit can be used to detect the temperature parameters inside the dryer body. The number of probe bodies can be increased according to the situation, and new air pressure and humidity detection functions can be added. After these data are transmitted to the control center, the rotation speed of the hollow shaft, the steam pressure inside it, etc. can be adjusted according to the situation to adjust the drying effect of the entire dryer body, ensuring that the water content of the sludge after drying is within the compliance range. The detection probe unit in this solution includes a mounting base and a probe base. The mounting base is fixed in the dryer body, and the probe base is removable, and the probe base can also be removed through the observation window. The baffle in this solution is driven by an electric adjustment cylinder instead of manual operation, and can automatically adjust the height.

[0007] Optionally, the upper portion of the mounting base is cylindrical, the lower portion of the mounting base is rectangular, a mounting groove is horizontally provided on the lower portion of the mounting base, a mounting hole and a rod barrel are provided on the side surface of the lower portion of the mounting base, the rod barrel is concentric with the mounting hole, a mounting rod is horizontally slidably provided on the rod barrel, the mounting rod can be inserted into the mounting hole, an L-shaped clamping block is provided at the upper end of the probe base, the clamping block can be inserted into the mounting groove, and a plurality of clamping holes are horizontally provided on the side wall of the clamping block, the mounting rod can be inserted into the clamping holes. In this solution, the clamping holes are provided on the clamping block of the probe base, and the mounting base is provided with a mounting rod, which can be inserted into the clamping holes to secure the clamping block, so that the probe base and the mounting base can be relatively fixed.

[0008] Optionally, the probe base is equipped with a power module and a wireless transmitter module. In this solution, the probe base can power itself and transmit data collected by the probe body, eliminating the need for wiring within the dryer body. This makes the improvement simple, convenient, and easier. Furthermore, a single power module can operate for a long time, eliminating the need for frequent replacement by staff.

[0009] Optionally, a scraper unit is provided on the upper portion of the inner wall of the dryer body, comprising a scraper seat, a scraper rod, a sliding rod, and a scraper blade. The scraper rod is rotatably mounted on the scraper seat, the sliding rod having a hollow cylindrical interior, the sliding rod being horizontally slidably mounted on the scraper rod, and the scraper blade being mounted on the sliding rod. A drive motor is provided on the outer wall of the dryer body, the output end of the drive motor extending into the interior of the dryer body and being coaxially fixedly connected to the scraper rod. This solution implements scraping of the paddles on the hollow shaft. In this solution, a scraper rod is provided, and a sliding rod and a scraper blade are provided on the scraper rod. When the scraper blade is required to operate, the scraper rod is rotated so that it contacts the outer wall of the hollow shaft blade. As the hollow shaft and the blade rotate, the scraper blade can scrape away the sludge because the vertical position of the scraper blade does not change. At the same time, because the sliding rod can slide on the scraper rod, the scraper blade and the paddle blade do not become stuck. When the scraper is not needed, just rotate the scraper rod to separate the scraper from the paddle.

[0010] Optionally, the scraper rod is provided with a plurality of flat keys, and the sliding rod is provided with a keyway, and the flat keys are slidably connected to the keyway. In this solution, the sliding rod and the scraper rod can only translate relative to each other but not rotate relative to each other, ensuring that the scraper rod can control the sliding rod to flip.

[0011] Optionally, a closed box is mounted on the side wall of the probe base, a linear cylinder is mounted in the closed box, an output end of the linear cylinder extends out of the closed box, and an auxiliary scraper is provided on the output end of the linear cylinder, the auxiliary scraper being capable of scraping off sludge on the scraper. In this embodiment, the auxiliary scraper is capable of scraping off sludge on the scraper.

[0012] Optionally, the auxiliary scraper includes a rectangular support plate, with brackets provided at the four corners of the support plate, and four auxiliary scraping rods provided on the brackets, the auxiliary scraping rods forming a rectangular shape and cooperating with the outer wall of the scraper plate. The auxiliary scraping rods can more easily scrape away the sludge on the scraper plate.

[0013] The working principle and beneficial effects of this solution are:

[0014] In this solution, a detection probe unit is installed inside the dryer body. The detection probe unit is removable and can be manually operated through a nearby observation window, which is very convenient. The function of the detection probe unit is to detect parameters such as the temperature inside the dryer body, and then transmit these parameters to the control center for analysis. Based on the analysis, the rotation speed of the hollow shaft, the height of the discharge port baffle, the steam pressure inside the hollow shaft, the feed amount, etc. are adjusted to adjust the sludge drying effect so that the water content of the sludge meets the standard when it is discharged. In this solution, a scraper can also be used to scrape off the sludge on the hollow shaft blades to ensure that the hollow shaft can transfer heat to the sludge in a timely manner.

[0027] The probe bodies 19 are all arranged on the probe base 10. The probe bodies 19 have the functions of temperature detection, air pressure detection and humidity detection respectively. The probe bodies 19 can adopt temperature sensors, air pressure sensors and humidity sensors. The probe base 10 is provided with a power module and a wireless transmission module.

[0028] The discharge port 3 includes a port located within the dryer body 1 and a discharge port 3. The port is composed of a fixed plate 23 and a baffle 22. The fixed plate 23 is vertically fixed to the inner wall of the dryer body 1 and forms an independent discharge space with the inner wall. The baffle 22 slides vertically on the fixed plate 23. An electric adjustment cylinder 21 is installed on the outer wall of the dryer body 1. The lower end of the baffle 22 extends below the dryer body 1 and is connected to the output end of the electric adjustment cylinder 21.

[0029] A scraper unit is installed on the upper inner wall of the dryer body 1, further away from the observation window 5 than the detection probe unit. The scraper unit includes a scraper seat 20, a scraper rod 24, a sliding rod 26, and a scraper blade 16. The scraper seat 20 is fixedly mounted on the inner wall of the dryer body 1. The scraper rod 24 is rotatably mounted on the scraper seat 20, with both ends of the scraper rod 24 extending outward from the scraper seat 20. The sliding rod 26 is hollow and cylindrical in shape. It slides horizontally on the scraper rod 24 and is key-connected to the scraper rod 24. The key connection is as follows: the scraper rod 24 is provided with several flat keys 25, and the sliding rod 26 is provided with a key slot. The flat keys 25 are slidably connected to the key slot. The scraper blade 16 is fixedly mounted on the sliding rod 26. Several elastic tie bars 27 are fixedly mounted on the inner wall of the scraper seat 20 and are fixedly connected to the sliding rod 26. A driving motor 4 is provided on the outer wall of the dryer body 1 , and an output end of the driving motor 4 extends into the interior of the dryer body 1 and is coaxially fixedly connected to the scraper rod 24 .

The block 11 on the probe holder 10 is then inserted into the mounting groove 17 of the mounting seat 7. The mounting rod 9 is then manually pushed inward so that it is inserted into the locking hole 18 on the block 11 to complete the fixation. At this point, the probe body 19 can collect parameters such as temperature, humidity, and air pressure inside the dryer body 1. Based on these parameters, the operator can adjust the rotation speed of the hollow shaft 6 and the steam pressure therein, as well as the height of the baffle 22. To adjust, simply activate the electric adjustment cylinder 21, which drives the baffle 22 upward or downward, changing the discharge amount from the discharge port 3 until the sludge moisture content meets the standard. If the outer wall of the hollow shaft 6 paddle is covered with excessive sludge that cannot be removed, the drive motor 4 can be activated to rotate the scraper rod 24, which in turn rotates the sliding rod 26. The scraper blade 16 on the sliding rod 26 can contact the outer wall of the hollow shaft 6 paddle and scrape away the sludge. When there is too much sludge on the scraper 16, the scraper 16 is restored to a horizontal position, and then the linear cylinder 13 in the closed box 12 is started. The linear cylinder 13 drives the support plate 14 and the auxiliary scraper rod 15 thereon to contact the scraper 16, so that the sludge on the scraper 16 can be scraped off, and the auxiliary scraper rod 15 can be cleaned by removing the entire detection probe unit.
