Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, and in particular to a calcium fluoride wet sludge drying treatment conveying system and a working method. Background Art

[0002] Calcium fluoride sludge can be used to make ceramics after drying, and it can be used as a resource by calcining domestic sewage sludge, adding cement, etc. However, calcium fluoride sludge will clump after drying. At this time, in order to ensure the mixing of sludge and other materials in the next process, the dried sludge is usually refined during transportation. However, the existing refinement treatment mostly uses extrusion to crush and refine the dried sludge to avoid generating a large amount of dust during transportation. In this treatment process, a part of the dried sludge will adhere to the conveyor belt after being squeezed, making it difficult to separate the sludge from the conveyor belt during transportation, and then the material feeding is not smooth. At the same time, the sludge will be compacted during extrusion, that is, there are still lumps of sludge in the sludge after extrusion, and the sludge refinement effect is not good, resulting in low quality of the conveyed material.

[0003] Chinese invention patent: Publication number is "CN118833991A", and the name is "A deep drying system for coordinated treatment of organic solid waste". It discloses a deep drying system for coordinated treatment of organic solid waste, including a base and a drying box fixedly installed on the top of the base and divided from left to right by two partitions into a paving area, a primary drying area, and a secondary drying raking area. The left and right rake claws move back and forth synchronously to rake and scatter the sludge undergoing secondary drying. The raking and scattering action can effectively break up the agglomerates in the sludge, increase the surface area of ​​the sludge particles, and make the water inside the sludge easier to evaporate. Combining the raking and scattering action with the secondary thermal drying process can further improve the drying efficiency of the sludge. However, the rake claws set in this technical solution have limited dispersion effect on the sludge and cannot completely refine the block sludge in the sludge. Summary of the invention

[0014] The present invention also provides a working method of the calcium fluoride wet sludge drying treatment and conveying system suitable for the design of the present invention, comprising the following steps:

[0016] Step 2: The shovel guide plate shovels the wet sludge on the conveyor belt and gathers it, and then the shovel bucket guides it to the housing;

[0017] Step 3: The first motor drives the pinion, the gear, the connecting shaft, the pulley, the synchronous belt, the pulley, and the connecting sleeve in sequence through the load-bearing shaft to rotate the pressure guide ring, rotate the protrusion to the position of the wheel seat, and the wheel seat slides along the protrusion to drive the spring body and the guide prism in sequence to drive the blocking cover to move up and open, so that the wet sludge on the bucket enters the shell;

[0020] Step 6: The first motor drives the small gear, the large gear, and the connecting shaft in sequence to drive the baffle to rotate. When the discharge hole rotates to coincide with the shell, the crushed and dispersed wet sludge in the shell falls onto the conveyor belt and is transported to the next process.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The two shovel guide plates arranged at an angle at the bottom can be used to shovel off the sludge attached to the conveyor belt due to extrusion, so that the sludge and the conveyor belt can be separated, and the transported sludge can be smoothly dropped off when it is transported to the end of the conveyor belt, thereby ensuring the normal conveying and unloading operation. At the same time, the two shovel guide plates are symmetrical and inclined toward the middle of the conveyor belt, so that the sludge dispersed by extrusion can be gathered and guided into the shell by the rear bucket to contact with the rotating crushing knife in the shell to crush the sludge and make it fully refined, so that the transported sludge can meet the use of the next process and improve the quality of its conveyed material.

[0023] 2. Under the action of the baffle plate, the lower part of the shell can be blocked. When the load-bearing shaft drives the crushing knife to rotate, the small gear drives the large gear to rotate slowly, and then drives the baffle plate on the connecting shaft to rotate slowly. When the discharge hole on the baffle plate moves to the shell, the sludge in the shell will fall through the discharge hole onto the conveyor belt of the conveyor and continue to be transported. This cycle can effectively increase the residence time of the sludge in the shell, so that the sludge and the crushing knife can fully contact, thereby ensuring the crushing force of the crushing knife on the sludge.

[0024] 3. When the connecting shaft drives the baffle plate to rotate, it will also drive the connecting sleeve to rotate through the synchronous belt, and then drive the pressure guide ring to rotate. When the protrusion on the pressure guide ring moves to the pressure wheel, the spring body will push the wheel seat to move the baffle cover up, so that the connection between the shell and the bucket is opened, allowing the sludge to enter the shell. Then, when the protrusion on the pressure guide ring moves away from the pressure wheel, the lower end of the pressure guide ring will press the pressure wheel to reset the baffle cover and continue to block the connection between the shell and the bucket. This cycle can effectively crush the sludge in a closed environment to reduce the dispersion of dust during the conveying and crushing process, thereby improving the quality of the conveying environment.

[0038] like Figure 1 and Figure 5 As shown, the bucket 6 is composed of two vertical plates and a flat plate. One end of the flat plate is in contact with the conveyor belt of the conveyor 1, and the other end is inclined away from the conveyor belt and fixedly connected to the shell 5. The two vertical plates have a large distance between the end close to the shovel guide plate 4 and a small distance away from the shovel guide plate 4, and are fixedly connected to the shell 5. In order to ensure that the sludge enters the dispersion part smoothly, the inclination angle of the bucket 6 should not be too large, preferably 5-15°. In order to allow the wet sludge to move smoothly to the flat plate of the bucket 6, an extension plate 11 is also provided at the end of the vertical plate of the bucket 6 close to the shovel guide plate 4.

The wheel seat 25 slides along the protrusion 36 and drives the spring body 24 and the guide prism 12 in sequence, thereby driving the blocking cover 10 to move up and open, so that the wet sludge on the bucket 6 enters the housing 5;

[0046] Step 4: The first motor 8 continues to rotate the pressure guide ring 20, rotating the protrusion 36 away from the wheel seat 25, and the wheel seat 25 continues to slide along the protrusion 36 until the protrusion 36 slides out, driving the spring body 24 and the guide prism 12 in turn, thereby driving the blocking cover 10 to move down and close;

[0047] Step 5: The first motor 8 drives the crushing blade 28 to rotate through the bearing shaft 13 to crush the wet sludge in the housing 5. During this process, the baffle 9 blocks the wet sludge in the housing 5 so that the wet sludge can fully contact the crushing blade 28 for crushing, so that the wet sludge can be fully refined;

[0048] Step 6, the first motor 8 drives the small gear 22, the large gear 14, and the connecting shaft 17 in sequence to drive the baffle plate 9 to rotate. When the discharge hole 18 rotates to overlap with the shell 5, the crushed and dispersed wet sludge in the shell 5 falls onto the conveyor belt and is transported by the conveyor belt to the next process.
