Description

Technical Field

[0001] The utility model relates to the technical field of material conveying and processing, in particular to a sealed chute for a unilateral plough-type tripper. Background Art

[0002] A plough-type tripper is a high-efficiency discharging device for a belt conveyor, which is used for bin loading of bulk granular or powdery materials and is widely used in industries such as electric power, metallurgy, chemical industry, grain, mining and coal transportation. When the plough-type tripper discharges materials, the bulk materials on the belt surface of the belt conveyor are turned and dialed by a plough-shaped baffle to the blanking chute, and the bulk materials are transferred and bin-loaded through the chute. A large amount of dust is generated during this process due to the material drop and the action of floating air.

[0003] The traditional discharging chute of the plough-type tripper is generally open and lacks effective dust suppression measures. This not only pollutes the working environment, but also poses a threat to the physical health of operators, and more importantly, it cannot meet the increasingly strict environmental protection requirements. Therefore, how to effectively suppress the dust generated during the discharging process of the plough-type tripper has become an urgent technical problem to be solved. Summary of the Utility Model

[0013] By adopting the above technical solution, during use, in order to keep the wear-resistant linings fixed, fasteners composed of countersunk bolts are used for fixing. This fixing method is firm in installation and convenient in disassembly.

[0014] Preferably, the wear-resistant lining is a rare earth alloy lining with high impact resistance and high wear resistance, and its thickness is 20 mm.

[0015] By adopting the above technical solution, during use, the wear-resistant lining is made of rare earth alloy, which further improves its wear resistance.

[0016] Preferably, the inlet dust-proof curtain is composed of multiple thin strip-shaped soft tapes and is fixed to the inlet of the sealing cover by rivets. The height of the inlet dust-proof curtain meets the lifting of the plow plate of the discharger to further suppress dust.

[0017] By adopting the above technical solution, during use, the inlet dust-proof curtain is composed of multiple thin strip-shaped soft tapes, mainly to facilitate the passage of materials, and the setting of the inlet dust-proof curtain can further prevent external dust from entering.

[0018] Preferably, the dust removal interface and the dust collector are sealed by flange connection to ensure that dust will not leak during the dust removal process.

[0019] By adopting the above technical solution, during use, the connection between the dust removal interface and the dust collector is realized by flange connection. This connection method keeps the connection part sealed, preventing dust from leaking out and affecting the environment.

[0020] Preferably, the sealing cover and the hopper chute body are connected by a detachable connection method to facilitate the maintenance and replacement of the wear-resistant lining plate.

It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom surface" and "top surface" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.

[0031] The present utility model discloses a sealing chute for a unilateral plough-type unloader, as Figures 1 to 3 shown, which includes a funnel chute body 1, and a support base 2 made of angle steel L75x6 of Q335B material is welded to the bottom thereof by a continuous weld. The weld height is equal to the minimum steel plate thickness, ensuring a stable structure and strong load-bearing capacity.

[0032] An unloader 3 is arranged on one side of the funnel chute body 1 for controlling the discharge of materials. A sealing cover 4 is arranged outside the funnel chute body 1. Wear-resistant liners 7 are provided on the impact side walls and inclined sections inside the sealing cover 4 and the funnel chute body 1 to prevent material wear. The wear-resistant liner 7 is made of an impact-resistant high-wear-resistant rare earth alloy liner with a thickness of 20 mm. This material has undergone strict performance tests and has proven to have significant advantages in impact resistance and wear resistance. The wear-resistant liner 7 is firmly fixed on the inner side wall of the funnel chute body 1 by fasteners 8. The number of fasteners 8 per square meter is not less than 13 sets, ensuring that the wear-resistant liner 7 will not loosen or fall off during the long-term use of the chute. Countersunk head bolts 81 are particularly selected among the fasteners 8. Their design can prevent the materials from colliding with the bolt heads during the transmission process, further enhancing the service life and safety of the equipment. At the same time, the sealing cover 4 and the funnel chute body 1 are connected in a detachable manner, specifically by bolts and nuts, so as to facilitate the maintenance and replacement of the wear-resistant liner 7.

[0033] The sealing cover 4 further includes an inlet dust-proof curtain 5 arranged at the material discharge place of the unloader 3. The inlet dust-proof curtain 5 is arranged at the inlet of the sealing cover 4. The inlet dust-proof curtain 5 is composed of multiple thin strip-shaped soft tapes and is fixed to the inlet of the sealing cover 4 by rivets. The height of the inlet dust-proof curtain 5 meets the lifting of the plough plate of the unloader 3, further suppressing dust. In addition to being composed of multiple thin strip-shaped soft tapes, the inlet dust-proof curtain 5 can also be made of materials with higher wear resistance and flexibility, such as special rubber or polyurethane materials. These materials can better adapt to the lifting movement of the plough plate of the unloader 3 and further improve the dust-proof effect.

[0034] A dust removal interface 6 is provided at the top of the sealing cover 4. The dust removal interface 6 is used to connect to a dust collector, which is used to conduct negative pressure air extraction inside the hopper chute body 1. The dust removal interface 6 and the dust collector are connected by a flange, and a sealing gasket is provided at the flange connection to ensure that dust will not leak during the dust removal process. This connection method has the advantages of simple installation and good sealing performance, and can ensure that dust will not leak during the dust removal process. When selecting the connection method, the actual use environment of the equipment and the requirements for dust removal efficiency need to be considered.

[0035] Working principle: A sealing chute for a unilateral plough-type discharger 3 designed by the present utility model realizes the discharge of materials under the control of the discharger 3, and the materials enter the hopper chute body 1 through the discharge. During the material transmission process, the wear-resistant lining plate 7 effectively protects the inner side walls of the sealing cover 4 and the hopper chute body 1, preventing the equipment from being worn by the materials. At the same time, the stable structure of the support base 2 provides stable support for the entire chute, ensuring the safe operation of the equipment. The design of the sealing cover 4 and the inlet dust-proof curtain 5 effectively prevents dust leakage. At the same time, the dust collector connected to the dust removal interface 6 conducts negative pressure air extraction inside the hopper chute body 1, further reducing dust leakage and improving the working environment.

[0036] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
