Description

Technical Field

[0001] This utility model relates to the field of material sorting technology, and in particular to a chain plate feeding and mud removal device. Background Technology

[0002] In many industries such as construction, mining, and building materials processing, raw materials are often mixtures of various components, including soil and stones. Before further processing, it is necessary to effectively separate the soil from the stones and grade and screen them according to their size to meet the requirements of different production processes and product quality.

[0003] In existing chain plate feeding equipment, when processing mixtures of highly viscous mud and stones, the highly viscous mud often adheres to the chain plate. If it is not cleaned for a long time, it will clump and harden on the chain plate, making subsequent cleaning very cumbersome and corroding the chain plate, thus shortening the service life of the equipment.

[0009] Preferably, it also includes a conveyor belt, which is installed below the chain feeder and the mud-stone separator.

[0010] Preferably, the direction in which the chain plate feeder and the mud-stone separator transport the mud-stone mixture is opposite to the direction in which the conveyor belt transports the soil.

[0025] Example 1

[0026] Please refer to the attached document. Figure 1-5This application provides a chain plate feeder for desliming, including a chain plate feeder 1 and a mud-stone separator. The mud-stone separator is installed at the discharge port of the chain plate feeder 1. A desliming device 3 is provided below the chain plate of the chain plate feeder 1. The desliming device 3 includes an air knife 301, which includes two assembled upper blades 3011 and lower blades 3012, and side sealing plates 3013 surrounding the upper blades 3011 and lower blades 3012. A fixing rod 3014 is fixedly inserted through the 013. The two ends of the fixing rod 3014 are fixedly installed on both sides of the inner side wall of the chain plate feeder 1. A plurality of sequentially connected chambers 3015 are formed between the upper blade 3011 and the lower blade 3012. One end of the plurality of sequentially connected chambers 3015 is connected to the air inlet 3016 of the blade, and the other end is connected to the exhaust port 3017 of the air knife 301. The exhaust port 3017 sprays towards the chain plate feeder 1.

[0027] During operation, workers use a loader or excavator to pour the mud-stone mixture to be separated onto the chain plate of the chain plate feeder 1. The chain plate feeder 1 then evenly distributes the mud-stone mixture into the mud-stone separator. As the chain plate continues to move into the support frame of the chain plate feeder 1, the mud removal device 3 located inside the support removes the highly viscous mud adhering to the chain plate of the chain plate feeder 1. The air knife 301 employs multiple interconnected chambers 3015, with different volumes between the upper blade 3011 and the lower blade 3012. This allows for thorough mixing of the compressed hot airflow from the air inlet 3016, significantly reducing air velocity and pressure unevenness caused by the uneven structure of the air inlet 3016 along its length. This ensures the uniformity and continuity of the airflow at the exhaust port 3017. The exhaust port 3017 is located along the length of the air knife 301, allowing for... The airflow is emitted at high speed and linearly, providing more complete coverage of the chain plate. It is then sprayed onto the chain plate through exhaust port 3017, drying the highly viscous soil and blowing it out of the chain plate feeder 1. This prevents corrosion of the chain plate, extends its service life, and avoids the problem of highly viscous soil adhering and clumping on the chain plate. The fixing rod 3014 provides support for the air knife 301, and the exhaust port 3017 is fixed in direction after the air knife 301 is fixed, forming a stable airflow for easy blowing of highly viscous soil. The side sealing plate 3013 mainly blocks the gap between the upper blade 3011 and the lower blade 3012, which is prone to air leakage, thus providing a seal. The mud-stone separator then separates the mud-stone mixture fed into the chain plate feeder 1. The separated soil falls from the bottom of the mud-stone separator, while the separated stones are transported to the finished product area for processing. Since the chain plate feeder 1 is a conventional machine in this field, its structure will not be described in detail.

[0028] Specifically, the mud-stone separator includes a first roller screen 4 and a second roller screen 6. The first roller screen 4 separates the mud-stone mixture fed by the chain feeder 1, and then the separated stones are fed into the second roller screen 6 for further scraping and separation of the mud on the stones, thereby improving the separation efficiency of the mud-stone mixture.

[0029] Specifically, the first roller screen 4 includes a motor 401, a reducer 402, a drive screen shaft 403, a driven screen shaft 404, a chain drive device 405, and cutter discs 406. A support plate 5 is provided on one side of the first roller screen 4. The motor 401 and the reducer 402 are mounted on the support plate 5. The motor 401 is connected to the reducer 402 through the chain drive device 405. The reducer 402 drives the drive screen shaft 403 to rotate through a coupling. The drive screen shaft 403 drives the driven screen shaft 404 to rotate through the chain drive device 405. The chain drive device 405 includes a drive sprocket 407 and a chain 408. The chain 408 is sequentially and alternately sleeved on the outer side of the drive sprocket 407 adjacent to one end of the driven screen shaft 404. Several cutter discs 406 are respectively mounted on the drive screen shaft 403 and the driven screen shaft 404. The second roller screen 6 has the same structure as the first roller screen 4. The motor 401 drives the input shaft of the reducer 402 to rotate. The output shaft of the reducer 402 is connected to the drive screen shaft 403 via a coupling, driving the drive screen shaft 403 to rotate. The drive screen shaft 403 drives the drive sprocket 407 on the adjacent driven screen shaft 404 to rotate via the drive sprocket 407 and chain 408 mounted on the drive screen shaft 403. The driven screen shafts 404 are arranged laterally along the conveying direction of the roller screen, and the cutter discs 406 are arranged laterally along the surface of either the drive screen shaft 403 or the driven screen shaft 404. One end of the drive screen shaft 404 is fitted with a drive sprocket 407, and a drive chain 408 is sequentially and alternately fitted on the outer side of the drive sprocket 407 adjacent to one end of the driven screen shaft 404. The chain drives distribute the material to each roller, resulting in good stability, good synchronization, and relatively low energy consumption. This effectively reduces the overall size, weight, energy consumption, and frequency of the equipment, as well as improving feeding stability. Meanwhile, the cutter discs 406, which are staggered on the drive screen shaft 403 and the driven screen shaft 404, scrape the mud off the stones. At the same time, the mud falls from the gap between the drive screen shaft 403 and the driven screen shaft 404, thus completing the separation of mud and stone.

[0030] Specifically, it also includes a conveyor belt 7, which is installed below the chain feeder 1 and the mud-stone separator. The separated soil is transported to the next operating area via the conveyor belt 7 below the chain feeder 1 and the mud-stone separator.

[0031] Specifically, the chain feeder 1 and the mud-stone separator transport the mud-stone mixture in the opposite direction to the direction the conveyor belt 7 transports the soil. By setting the opposite direction, the separated soil and stones are transported to different areas for the next operation.

[0032] Example 2

[0033] Please refer to the appendix. Figure 1-5 The difference between this embodiment and embodiment 1 is that the side of the air knife 301 near the exhaust port 3017 is conical.

[0034] Specifically, the air inlet 3016 of the air knife 301 is disposed on the upper blade 3011 and the side sealing plate 3013.

[0035] Specifically, the upper blade 3011 and the lower blade 3012 are provided with multiple grooves on their opposing surfaces. The extension direction of the grooves is consistent with the length direction of the air knife 301. The multiple grooves are arranged at intervals in the air knife 301 to form multiple chambers 3015. Two adjacent grooves are connected by a channel 8 provided between the upper blade 3011 and the lower blade 3012. The chambers 3015 are connected to the exhaust port 3017 by the channel 8.

[0036] These grooves, distributed on the upper blade 3011 and lower blade 3012, and since the upper blade 3011 and lower blade 3012 are always assembled together, can be sealed, thus forming chambers 3015. Obviously, the compressed hot airflow near the inlet 3016 enters the first chamber 3015 first. Because the first chamber 3015, connected to the inlet 3016, has a larger volume, it can mix the airflow, initially forming a uniform airflow, preparing for further mixing in subsequent chambers 3015. As the airflow sequentially enters different chambers 3015, the subsequent chambers 3015 further mix the incoming airflow, maintaining the consistency of the airflow direction. Although still relatively poor, it significantly improves the consistency of airflow direction compared to the first chamber 3015, and further reduces the momentum and airflow disturbance caused by the airflow in the first chamber 3015. The volume of the chamber 3015 is progressively reduced from the inlet 3016 to the outlet 3017. This arrangement not only avoids airflow disturbance caused by pressure changes, but the gradually decreasing size of the chamber 3015 presents a flattened design, which is conducive to forming a unidirectional airflow and improving the uniformity of airflow along the length of the air knife 301. The gap size of the channel 8 is much smaller than that of the chamber 3015, further reducing the airflow pressure, increasing the airflow velocity, and improving the purging power of the air knife 301.

[0037] Specifically, a gasket 2 is provided between the upper blade 3011 and the lower blade 3012. The gasket 2 allows for adjustment of the distance between the upper blade 3011 and the lower blade 3012 by changing the thickness of the gasket 2, thereby adjusting the volume of the chamber 3015. This facilitates the production of a batch of air knives 301 to meet different needs, while also increasing the stability and sealing of the connection between the upper blade 3011 and the lower blade 3012, thus mitigating production irregularities.

[0038] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
