Description

Technical Field

[0001] The utility model relates to the technical field of sludge drying equipment, in particular to a sludge drying machine dust cleaning device. Background Art

[0002] Sludge drying equipment is used to treat sludge generated in sewage treatment plants or industrial production. Sludge usually contains a large amount of water and organic matter. Improper treatment will cause environmental pollution and health risks. Sludge drying equipment can remove moisture from the sludge, thereby reducing the volume and weight of the sludge, while improving the stability of the sludge and its utilization value after treatment.

[0003] When existing sludge drying equipment is in the process of sludge drying, if sludge gets stuck in the equipment or large foreign objects fall into the equipment, it is very easy to cause safety problems such as scraper damage after startup. In addition, for continuous production lines, when the upstream and downstream equipment structures fail to operate normally, the sludge cannot be transported and processed in time, resulting in accumulation, and the equipment cannot realize self-detection of problems, which in turn damages the equipment.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0031] like Figure 1-Figure 3 As shown, in one embodiment, a sludge dryer cleaning device includes: a first detection component 1, a second detection component 2, a first cleaning conveying component 3, and a second cleaning conveying component 4. The first detection component 1 is disposed on one side of the second cleaning component for detecting torque; the second detection component 2 is disposed on the other side of the second cleaning component for detecting material level.

[0032] Furthermore, the first dust cleaning conveying assembly 3 is arranged at the end of the second dust cleaning conveying assembly 4, and the first dust cleaning conveying assembly 3 is used to convey the dirt scraped by the second dust cleaning conveying assembly 4; the second dust cleaning conveying assembly 4 is used to scrape the dirt at the bottom of the sludge dryer.

[0033] Please continue reading Figure 1-Figure 3 In this embodiment, the first detection assembly 1 includes a torque sensor, which is installed on one side of the conveyor chain 41. The torque sensor is used to detect the torque of the cleaning scraper 42 during operation. Before the cleaning scraper 42 operates normally, a torque range is set. This value includes the normal scraping volume and the weight of the cleaning scraper 42 itself. During normal operation, the torque sensor detects the operating torque value. If the operating torque exceeds the set torque, it indicates that the scraper has a fault. At this time, the torque sensor will issue a control signal to automatically shut down the first cleaning conveyor assembly 3 and the second cleaning conveyor assembly 4 and issue an alarm. This fault can be categorized into two types: one is that the scraping volume exceeds the designed amount, and the other is that a rod-shaped or large foreign object is stuck in the scraper.

[0034] Please continue reading Figure 1-Figure 3In this embodiment, the second detection component 2 includes a level meter, which is arranged on the other side of the conveyor chain 41 and is used to detect the material level of the discharging scraper 31. The level meter is connected to a detection blade 21, which is used to detect the height of the dirt. The rotary damper level machine switch uses an AC micromotor that is decelerated to drive the detection blade 21 to rotate slowly. When the equipment is running, when the transported sludge and other dirt causes the material level to rise, the rotation of the detection blade 21 will be blocked and the main shaft of the detection mechanism will produce a rotational displacement. This displacement first causes a connected microswitch to operate, sending a signal that there is material, and then another connected microswitch operates, cutting off the power supply of the micromotor to stop it from rotating. As long as the material level remains unchanged, this state will continue, which can effectively prevent the first dust cleaning and conveying component 3 from being blocked and causing damage to the second dust cleaning and conveying component 4 at the bottom of the sludge dryer.

[0035] Please continue reading Figure 1-Figure 3 In this embodiment, the first dust cleaning component includes a discharging scraper 31 , and a feed port 32 is provided at the bottom of one side of the discharging scraper 31 , and a discharging port 33 is provided at the top of the other side.

[0036] Furthermore, a first driving motor 34 is provided at the top of the discharge port 33 for driving the discharge scraper 31 to operate continuously.

[0037] Please continue reading Figure 1-Figure 3 In this embodiment, the second dust cleaning conveying assembly 4 includes a conveying chain 41 and a dust cleaning scraper 42. The conveying chain 41 is symmetrically arranged on both sides of the dust cleaning scraper 42 to drive the dust cleaning scraper 42. The scraper is L-shaped and can effectively scrape away sludge and other dirt at the bottom of the sludge dryer.

[0038] Furthermore, a second drive motor 44 is provided on the side of the conveying chain 41 close to the material level meter, which drives the conveying chain 41 to drive the cleaning scraper 42 to continuously rotate through the reduction motor; a scraper tensioning mechanism 43 is also provided at the end of the conveying chain 41 for adjusting the tightness of the cleaning scraper 42.

[0039] Working Principle: The second drive motor 44 drives the drive chain to drive the cleaning scraper 42 to operate continuously, scraping away sludge and other dirt at the bottom of the sludge dryer and conveying it to the feed port 32 of the discharge scraper 31 on one side. The first drive motor 34 then drives the discharge scraper 31 to lift it horizontally and vertically, conveying the sludge and other dirt to the designated location before discharging it from the discharge port 33. The lowering of the equipment position can effectively reduce processing costs and operational difficulty. If sludge gets stuck in the equipment or large pieces of foreign matter fall into the equipment, the abnormal torque will be detected by the torque detection component and a shutdown command will be issued to prevent damage to the equipment. If an abnormal material level occurs, the material level detection component will send an electrical signal to the upstream equipment to prevent further accumulation of sludge and damage to the equipment.

[0040] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
