Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt cleaning, in particular to a filter press soil slag conveyor belt cleaning device. Background Art

[0002] During the filtration process, solid matter is discharged through the conveyor belt at the bottom, but the bottom material often remains on the surface of the conveyor belt. The traditional cleaning method is manual flushing, which is time-consuming and labor-intensive, and increases labor costs. At the same time, since there is very little water in the solid matter dropped from the filter press, they are generally agglomerated plates. These plates will waste a lot of storage space during transportation and storage, resulting in an increase in the number of transfers or storage times.

[0003] The Chinese utility model patent with announcement number: CN215973615U discloses a conveying device with an anti-adhesion structure for slag processing. This device can drive the rolling brush cylinder to convey along the surface of the slag conveyor belt, so that the slag can roll into the slag panel, which is beneficial for the rolling brush cylinder to carry out docking and cleaning of the slag conveyor belt surface with the slag rolling into the slag panel. At the same time, the cleaning equipment is installed on the nozzle mounting frame to facilitate the cleaning and flushing of the bonded slag, and the scraping of the slag bonded inside, which is beneficial for the later transportation of slag, flushing and cleaning of the bonded slag, and contributing to the normal operation of the slag processing and conveying device.

[0004] In the above-mentioned device and the prior art, cleaning the conveyor belt by liquid not only causes waste of resources, but also has disadvantages in the cleaning effect. When the filter press releases the debris, the debris falls directly onto the pulley. In this case, the debris will continuously impact the surface of the conveyor belt, which will cause depressions on the surface of the conveyor belt or the debris will be directly embedded in the surface of the conveyor belt. This situation makes it impossible to completely clean the conveyor belt by simple water flushing. Utility Model Content

A crushing frame 201 is fixedly installed at one end close to the main pulley 104, and a plurality of crushing shafts 202 are rotatably installed in the crushing frame 201. A crushing motor is arranged outside the crushing frame 201, and the output shaft of the crushing motor is fixedly connected to the crushing shaft 202. A plurality of crushing teeth are arranged on the crushing shaft 202, and the crushing teeth on the plurality of crushing shafts 202 are staggered with each other in the crushing frame 201, so that the crushing shaft 202 can crush the soil debris passing through the crushing frame 201 when rotating, so that the soil debris can be in a loose state.

[0019] like Figure 2 , Figure 3 As shown, a sliding block 206 is also slidably installed on the crushing frame 201, and a telescopic spring 204 is fixedly installed on one side of the sliding block 206, and the other end of the telescopic spring 204 is fixedly installed on the crushing frame 201. A scraper 205 is rotatably installed on the sliding block 206, and a rotating torsion spring is fixedly installed on the scraper 205, and the other end of the rotating torsion spring is fixedly installed on the sliding block 206. One end of the scraper 205 contacts the surface of the conveyor belt 103, and an arc scraper is provided at the end of the scraper 205 that contacts the conveyor belt 103. The arc scraper fits the shape of the conveyor belt 103, and the scraper 205 scrapes off debris on the surface of the conveyor belt 103 through the arc scraper, and the rotating torsion spring and the telescopic spring 204 are both provided to provide activity space for the scraper 205. When a metal object or other hard object is embedded in the conveyor belt 103, the telescopic spring 204 and the rotating torsion spring can allow the scraper 205 to avoid the metal object, thereby preventing the arc scraper from being damaged.

[0020] like Figures 2 to 4As shown, a fixing frame 214 is fixedly installed on the side bracket 101, and a pressing bracket 212 is rotatably installed on the fixing frame 214. A plurality of pressing cylinders 213 are fixedly installed on the secondary pulley 102, and the moving end of the pressing cylinder 213 is rotatably installed on the pressing bracket 212. The connection between the pressing cylinder 213 and the pressing bracket 212 is arranged at an end of the pressing cylinder 213 away from the fixing frame 214. A pressing roller 215 is also rotatably installed on the end of the pressing bracket 212 away from the fixing frame 214, and the pressing roller 215 contacts the inner wall of the conveying belt 103 to press the conveying belt 103 for displacement. A slide plate 211 is also rotatably installed on the pressing bracket 212, and the slide plate 211 is away from the end of the pressing bracket 212. A side slider 209 is slidably installed, and the side slider 209 is slidably connected to the shipping plate 207. A cleaning shaft 210 is rotatably installed on the side slider 209. A cleaning motor is provided on the side slider 209, and the output shaft of the cleaning motor is fixedly connected to the cleaning shaft 210. A plurality of extruded bone ribs for cleaning are provided on the cleaning shaft 210. The extruded bone ribs have multiple hollows, and the extruded bone ribs are evenly distributed on the cleaning shaft 210. The extruded bone ribs on the cleaning shaft 210 are staggered with each other to avoid dead angles in the cleaning of the extruded bone ribs. The end of the extruded bone ribs away from the cleaning shaft 210 contacts the outer surface of the conveyor belt 103, and the cleaning shaft 210 can cooperate with the pressing roller 215. The cleaning shaft 210 and the pressing roller 215 are as follows Figure 2 As shown, it is arranged in an offset manner. After the pressing roller 215 presses the conveyor belt 103, if there are some embedded or unremovable objects on the outer surface of the conveyor belt 103, the outer surface of the conveyor belt 103 can be scratched with force by pressing the roller 215 and the extrusion bone on the cleaning shaft 210, thereby achieving the purpose of cleaning the outer surface of the conveyor belt 103. The end of the side slider 209 away from the slide plate 211 is also fixedly installed with a pressing spring 208, and the other end of the pressing spring 208 is fixedly installed on the outer side of the shipping plate 207.

[0021] Working principle: When the device is in use, the slag cake dropped from the filter press is transported through the conveyor belt 103. When the slag cake on the conveyor belt 103 is transported to the end close to the main pulley 104, the gravity and the arc scraper on the scraper 205 will scrape the slag cake from the outer surface of the conveyor belt 103, and the slag cake will fall from the scraper 205 into the crushing frame 201, allowing the crushing motor to drive the crushing shaft 202 to crush the slag cake, and the slag cake will fall out of the device from the crushing frame 201 after being crushed.

[0022] Since the slag cake falls freely on the conveyor belt 103, it is inevitable that there are some depressions on the conveyor belt 103 due to impact, or the slag cake is impacted and embedded in the outer surface of the conveyor belt 103. In this case, the arc scraper on the scraper 205 cannot completely clean the outer surface of the conveyor belt 103. In this case, the pressing cylinder 213 and the cleaning motor can be started, and the rotation direction of the cleaning motor is Figure 2 The conveyor belt 103 is rotated counterclockwise, and then the pressing cylinder 213 drives the pressing roller 215 to press the conveyor belt 103, so that the outer surface of the conveyor belt 103 is closer to the cleaning shaft 210. The cleaning shaft 210 and the extruded bone ribs rotate at this time to continuously scrape off the objects embedded on the outer surface of the conveyor belt 103.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
