Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to a head mechanism for an oily sludge conveyor. Background Technology

[0002] In the process of harmless treatment of oily sludge, scraper conveyors are used to transport the oily sludge in order to avoid spillage and odor during transportation. However, during the long-term operation of existing scraper conveyors, the conveyor chain inevitably accumulates oily sludge. Excessive oily sludge accumulation can increase the weight of the chain, causing it to sag, and in severe cases, it may even lead to chain breakage. Therefore, it is necessary to optimize the head structure of the conveyor to reduce the accumulation of oily sludge on the chain. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where oil sludge buildup on the chain increases chain weight, and to propose a new head mechanism for an oily sludge conveyor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a head mechanism for an oily sludge conveyor, including a head assembly and a drive assembly. The head assembly is fixedly connected to the main body shell of the conveyor. The head assembly includes a housing, on which a head shaft is rotatably mounted via several head bearings. Several head wheels are coaxially fixed on the head shaft. A cleaning shaft is installed inside the housing above the head shaft. A cleaning motor is driven and connected to the cleaning shaft parallel to the cleaning shaft. Several cleaning wheels, corresponding to the main chain of the conveyor, are fixedly mounted on the cleaning shaft. A cleaning component is installed inside the housing above each cleaning wheel. The drive assembly is driven and connected to the head shaft.

[0006] Preferably, the housing includes a head connector, a head end cover, a head cover assembly, a head side plate assembly, and a transitional irregular end flange. The head connector, head end cover, head cover assembly, and head side plate assembly form a whole and are connected to the main housing of the conveyor through the transitional irregular end flange.

[0007] Preferably, the cleaning assembly includes several drive pulleys, a belt, and several scrapers. A belt is fitted between two of the drive pulleys, and the lower surface of the belt contacts the cleaning wheel. Several scrapers are respectively arranged on both sides of the cleaning wheel, and the scrapers contact the lower surface of the belt.

[0008] Preferably, the scraper has a triangular cross-section.

[0009] Preferably, the outer surface of the belt is coated with an anti-stick coating.

[0010] Preferably, the bristles of the sweeping wheel are made of PA610 nylon filaments.

[0011] The beneficial effects of the sludge buffer conveyor proposed in this utility model are as follows: by setting a cleaning shaft and cleaning wheel in the head mechanism, the chain in operation can be cleaned, so that the chain will not increase in weight due to sludge adhesion; and by setting a cleaning component, the belt in the cleaning component and the scraper are used to clean the cleaning wheel in operation, so that the cleaning wheel can always keep the chain effectively clean.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: Refer to Figure 1-3A head mechanism for an oily sludge conveyor includes a head assembly 1 and a drive assembly 2. The head assembly 1 is fixedly connected to the main housing 3 of the conveyor. The head assembly 1 includes a housing. A head shaft 108 is rotatably mounted on the housing via several head bearing assemblies 106. Several head wheels 109 are coaxially fixed on the head shaft 108. A cleaning shaft 107 is installed inside the housing above the head shaft 108. A cleaning motor is drivenly connected to the cleaning shaft 107 parallel to the cleaning shaft 107. Several cleaning wheels 1010, corresponding to the main chain of the conveyor, are fixedly mounted on the cleaning shaft 107. A cleaning component is provided inside the housing above each cleaning wheel 1010. The drive assembly 2 is drivenly connected to the head shaft 108.

[0019] The sweeping motor drives the sweeping shaft 107 to rotate, which in turn drives multiple sweeping wheels 1010 to rotate. When the bristles on the surface of the rotating sweeping wheels 1010 come into contact with the chain moving below them, they sweep away the oil and sludge attached to the chain, so that the overall weight of the chain does not increase. This prevents the chain from becoming loose or breaking due to overweight, thus enabling the entire conveyor to achieve a more stable operating effect.

[0020] The housing includes a head connector 101, a head end cover 102, a head cover assembly 103, a head side plate assembly 104, and a transition irregular end flange 105. The head connector 101, the head end cover 102, the head cover assembly 103, and the head side plate assembly 104 form a whole and are connected to the conveyor body through the transition irregular end flange 105.

[0021] The bristles of the 1010 sweeping wheel are made of PA610 nylon filaments. PA610 nylon filaments are the most wear-resistant type in the nylon family. They have excellent resilience, temperature resistance, acid and alkali resistance, and mechanical properties. They are commonly used in toothbrushes, glass polishing brushes, fruit and vegetable cleaning brush rollers, industrial cleaning brushes, and other fields.

[0022] Example 2: Refer to Figure 4 The cleaning assembly includes several drive pulleys 1011, a belt 1012, and several scrapers 1013. A belt 1012 is installed between two drive pulleys 1011. The lower surface of the belt 1012 is in contact with the sweeping wheel 1010. Several scrapers 1013 are respectively provided on both sides of the sweeping wheel 1010. The scrapers 1013 are in contact with the lower surface of the belt 1012.

[0023] The scraper 1013 has a triangular cross-section. The tip of the triangular scraper 1013 contacts the surface of the belt 1012, so that the scraper 1013 can scrape off the sludge on the surface of the belt 1012 no matter which direction the belt 1012 moves from.

[0024] The outer surface of belt 1012 is coated with an anti-stick coating. The anti-stick coating is PTFE (polytetrafluoroethylene). By setting the anti-stick coating, the sludge can be prevented from sticking too firmly to belt 1012, so that scraper 1013 can achieve better scraping effect.

[0025] In use, when the chain of the conveyor body passes the head assembly 1, the cleaning shaft in the head assembly 1 drives multiple cleaning wheels 1010 to rotate. The rotating cleaning wheels 1010 use their surface bristles to sweep away the substances attached to the chain. When there is a lot of sludge attached to the outer end of the bristles of the cleaning wheels 1010, the drive pulley 1011 is activated. The drive pulley 1011 drives the belt 1012 to rotate, so that after the belt 1012 comes into contact with the bristles, the sludge on the bristles can be stuck to the surface of the belt 1012. When the belt 1012 moves to both sides of the cleaning wheels 1010, the scraper 1013 can scrape off the sludge carried out by the belt 1012. In this way, the cleaning wheel bristles can be cleaned, thus ensuring that the cleaning wheels always have a cleaning effect on the chain.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
