Description

TECHNICAL FIELD

[0001] The utility model relates to the field of environmental protection equipment, specifically relates to a sludge dewatering equipment. BACKGROUND

[0002] The horizontal centrifuge is an effective sludge dewatering equipment, and its main structure is shown in the figure Figure 1 The horizontal centrifuge comprises a casing (A), a motor (B), a transmission assembly (C), a central shaft (D), a differential (E) and a drum, wherein the differential (E) and the drum are arranged inside the casing (A), the motor (B) is arranged outside the casing, the central shaft (D) is located in the casing (A) in a large part, and a part of the central shaft (D) extends out of the casing (A) to be connected to the transmission assembly (C), the transmission assembly (C) is driven by the motor (B), and the differential (E) is generally close to the power input end of the central shaft (D), that is, close to the motor (B) and the transmission assembly (C). A separate drum bin is arranged in the casing (A), and the power input end of the differential (E) and a part of the transmission assembly (C) are located in the same equipment bin.

[0003] During long-time and high-load operation of the sludge dewatering centrifuge, the differential oil is affected by high temperature and high pressure, and the oil product may be oxidized and deteriorated. The main function of the differential oil is to lubricate, cool and clean the internal parts of the differential, and the quality of the oil product is crucial to the normal operation of the centrifuge.

[0004] A detachable part is arranged on the casing (generally the upper half) of the centrifuge corresponding to the equipment bin, and when the differential of the centrifuge is changed, the centrifuge is generally required to be stopped and placed, and then the detachable part is removed, and new oil is injected after the waste oil is allowed to flow freely and cleaned. The process of stopping the centrifuge for changing the differential oil is slow, which may cause the sludge dewatering operation to be in a long-time stagnation state, especially when the sludge treatment capacity is large, the long-time stop of the centrifuge has a more serious influence on the sludge dewatering operation.

[0005] In order to shorten the stop time of the centrifuge, the worker starts the centrifuge to run slowly when changing the differential oil, so as to accelerate the differential oil to be thrown out, thereby saving time. However, the centrifuge needs to run at a very slow speed, otherwise the waste oil of the differential will be thrown out from the detachable part and splashed everywhere; meanwhile, when the centrifuge runs slowly, the opened detachable part lacks protection, and there is a safety hazard. CONTENT OF THE UTILITY MODEL

[0006] In order to provide protection for the opened detachable part of the centrifuge, the utility model provides a protection oil receiving device, and the main technical scheme adopted is as follows:

[0007] A protective cover for oil changing of differential gear in a horizontal centrifuge, the key features of which are: a cover body, the cover body being semi-circular arc-shaped, the opening of the cover body facing downwards, the cover body having two opposing arc edges and two opposing straight edges, the straight edges being horizontally arranged;

[0008] Two oil receiving grooves are provided on the inner wall of the cover body. The two oil receiving grooves correspond one-to-one with the two straight edges. The oil receiving grooves are close to the corresponding straight edges. The oil receiving grooves are horizontally arranged, closed at both ends, and the openings of the oil receiving grooves face upwards.

[0009] The cover body can be temporarily installed on the detachable parts of the horizontal sludge dewatering centrifuge for protection. At the same time, it can further increase the centrifuge speed during oil changes, accelerate the outflow of waste oil from the differential, and further shorten the centrifuge downtime. The waste oil (viscous) thrown out by the differential during rapid operation adheres to the inner wall of the cover body. The waste oil at the top of the inner wall of the cover body does not easily drip down, while the waste oil on the side of the inner wall of the cover body slides down into the oil receiving tank. The cover body also serves to collect the waste oil. Attached Figure Description

[0022] After the cover body 1 and the transmission part guard cover 5 are connected, the shape of the cover body 1 and the transmission part guard cover 5 is similar to that of the detachable part of the original centrifugal machine, and the main function of the cover body 1 and the transmission part guard cover 5 is to temporarily replace the detachable part and receive the waste oil thrown out by the differential mechanism of the centrifugal machine. Of course, the differential mechanism itself also has a shell, and the differential mechanism oil is contained in the shell of the differential mechanism itself.

[0023] A handle 6 is arranged on the outer wall top of the cover body 1 and the transmission part guard cover 5, so as to facilitate disassembly and assembly

[0024] The cover body 1, the axial shield 4 and the transmission part shield 5 are all made of stainless steel plates.
