Description

Technical Field

[0001] The utility model relates to a protective cover for a coupling, in particular to the structure of the protective cover for the coupling. Background Art

[0002] Carnallite is usually produced into potassium chloride using the reverse flotation-cold crystallization process. The process involves removing sodium chloride from the carnallite pulp through reverse flotation to obtain low-sodium carnallite. After the low-sodium carnallite is cold-decomposed and crystallized, potassium chloride is obtained through screening, filtration, washing, and centrifugal drying. The entire production process requires the use of screening equipment, filtration equipment, washing equipment, centrifugal equipment, etc. Each device must be driven by a motor, and the device and the motor are connected by a coupling. Both ends of the coupling are equipped with connecting sleeves (refer to Figure 5 ), the two connecting sleeves are respectively connected to the motor shaft and the rotating parts of the equipment for power transmission. The coupling also serves as a safety device to prevent the connected parts from bearing excessive loads and play a role in overload protection.

[0003] When the coupling is subjected to excessive load, it may cause damage to the coupling itself. Since the coupling transmits large mechanical energy, when it is damaged, its own parts will fall off and fly away. The flying parts will damage surrounding equipment and injure nearby workers, posing a major safety hazard.

[0004] The existing method usually sets a protective plate on the outside of the coupling and fixes the protective plate to the equipment installation platform through angle iron. However, the existing protective plate cannot protect both ends of the coupling, has low protection performance and low safety factor. Moreover, the protective plate blocks the coupling from the outside, and the normal operation of the coupling cannot be simply and intuitively observed. When dealing with coupling failure, the entire protective cover needs to be disassembled, which is time-consuming and labor-intensive.

[0005] In addition, due to the different sizes of different equipment, the heights of different couplings from the equipment's installation platform are different after installation. It is necessary to produce protective plates of specific sizes and heights according to the couplings in different positions, which makes installation and use inconvenient.

[0006] The first purpose of the utility model is to solve the problem that the existing protective device cannot effectively isolate and protect the coupling, and when the coupling fails, the protective device needs to be disassembled, which is time-consuming and labor-intensive.

[0007] Another purpose is to solve the problem that the existing coupling protection device is not suitable for the isolation box protection of couplings with different installation heights and is inconvenient to use. Utility Model Content
