Description

Technical Field

[0001] This utility model relates to the field of limestone-gypsum wet desulfurization equipment optimization technology, specifically, it is a desulfurization vacuum belt conveyor anti-jamming roller mechanism. Background Technology

[0002] The desulfurization vacuum belt conveyor is a key piece of equipment in the limestone-gypsum wet desulfurization system, playing a vital role in the entire gypsum dewatering system. Its main function is to dewater the gypsum hydrocyclone underflow slurry with a solid content of about 50% and turn it into gypsum with a surface moisture content of less than 10% for comprehensive utilization. However, due to design, equipment selection and installation process issues, the failure rate remains high, seriously threatening the normal operation of the desulfurization facilities. If the defects cannot be eliminated in time, it can easily cause the environmental protection over-emission unit to shut down.

[0003] Vacuum belt conveyors suffer from a high failure rate due to their harsh working environment, complex system, and corrosive media. For existing equipment, reducing this failure rate remains a key focus of maintenance. One common issue is the high particle content and fine size of the slurry, which frequently leads to drive roller jamming after prolonged use. Furthermore, after a period of inactivity, restarting the equipment can cause the slurry flowing into the drive roller bearings to dry out. Its high viscosity can also cause the bearings to stick, resulting in a significant load on the power system during startup to allow the drive rollers to release the adhesion. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-jamming mechanism for desulfurization vacuum belt conveyors, so as to solve the problems that existing belt conveyors are prone to jamming due to high slurry viscosity, and that the power rollers are prone to sticking after the belt conveyor has been stopped for a long time.

[0005] To solve the above problems, the present invention adopts the following technical means:

[0006] A desulfurization vacuum belt conveyor anti-jamming roller mechanism includes a belt roller, with positioning columns coaxially mounted on both sides of the belt roller. One positioning column is coaxially connected to a power mechanism. The positioning column is rotatably mounted on a support frame. The support frame has a receiving gap for the positioning column to pass through. The outer wall of the positioning column is connected to the inner wall of the receiving gap by a bearing. The bearing is located within the receiving gap. A sealing cavity is constructed between the inner wall of the receiving gap and the outer wall of the positioning column. A sealing medium conveying mechanism is constructed within the support frame. The discharge end of the sealing medium conveying mechanism communicates with the sealing cavity.

[0007] Preferably, the sealing medium conveying mechanism includes a collection chamber disposed within the support frame, and the support frame is configured with a liquid outlet channel that connects the collection chamber and the sealing chamber. The liquid outlet channel serves as the discharge end. The support frame is also provided with a liquid delivery channel that connects the collection chamber to the outside. The liquid inlet end of the liquid delivery channel is connected to a pressure-maintaining water supply mechanism.

[0008] Furthermore, the collection chamber is coaxially arranged with the positioning column, the collection chamber is an annular cavity, and the liquid outlet channel is arranged around the axis of the collection chamber.

[0009] Furthermore, the outlet of the liquid outlet channel is located at the middle position of the sealing cavity along the axis of the positioning column.

[0010] Furthermore, the sealing medium delivery mechanism is used to pump clean water into the sealing cavity.

[0011] This utility model has the following beneficial effects during use:

[0012] The belt roller is installed and positioned by connecting the positioning column and the support frame. The receiving gap on the support frame creates a sealing cavity between the receiving gap and the positioning column. During operation, the sealing medium conveying mechanism continuously pumps clean water, the sealing medium, into the sealing cavity from its discharge end, and continuously sprays the water out from both ends of the receiving gap. This effectively prevents slurry from entering the receiving gap and causing roller jamming. Furthermore, after operation, allowing the sealing medium conveying mechanism to continue running for a period of time cleans the receiving gap, preventing the rubber material near the receiving gap from drying and adhering to the belt roller.

[0023] Please refer to Figures 1 to 3As shown, a desulfurization vacuum belt conveyor anti-jamming roller mechanism includes a belt roller 1. Positioning columns 2 are coaxially mounted on both sides of the belt roller 1. One of the positioning columns 2 is coaxially connected to a power mechanism 3, which is a rotary motor. The positioning column 2 is rotatably mounted on a support frame 4. The support frame 4 has a accommodating gap for the positioning column 2 to pass through. The outer wall of the positioning column 2 is connected to the inner wall of the accommodating gap via a bearing 5, which is located within the accommodating gap. A sealing cavity 6 is constructed between the inner wall of the accommodating gap and the outer wall of the positioning column 2. A sealing medium conveying mechanism is constructed within the support frame 4, and the discharge end of the sealing medium conveying mechanism communicates with the sealing cavity 6.

[0024] Thus, the belt roller 1 is installed and positioned by connecting the positioning column 2 to the support frame 4. The receiving gap on the support frame 4 forms a sealing cavity 6 between the receiving gap and the positioning column 2. During operation, the sealing medium conveying mechanism continuously pumps clean water, serving as the sealing medium, from its discharge end into the sealing cavity 6, and continuously sprays the clean water out from both ends of the receiving gap. This effectively prevents slurry from entering the receiving gap and causing roller jamming. Furthermore, after operation, allowing the sealing medium conveying mechanism to continue running for a period of time cleans the receiving gap, preventing the adhesive near the receiving gap from drying out and causing adhesion to the belt roller 1.

[0025] Specifically, the sealing medium conveying mechanism includes a collection chamber 7 located within the support frame 4. The support frame 4 has a liquid outlet channel 8 that connects the collection chamber 7 and the sealing chamber 6. The liquid outlet channel 8 serves as the discharge end. The support frame 4 also has a liquid delivery channel 9 that connects the collection chamber 7 to the outside. The liquid inlet end of the liquid delivery channel 9 is connected to a pressure-maintaining water supply mechanism.

[0026] In this way, the pressure-maintaining water supply mechanism continuously pumps clean water with a certain water pressure into the collection chamber 7, and allows the clean water to spray out from the liquid outlet channel 8 into the sealing chamber 6.

[0027] Furthermore, to better seal the gaps and facilitate subsequent cleaning, the collection chamber 7 is coaxially arranged with the positioning column 2. The collection chamber 7 is an annular cavity, and the liquid outlet channel 8 is arranged around the axis of the collection chamber 7.

[0028] Furthermore, the outlet of the liquid outlet channel 8 is located at the middle position of the sealing cavity 6 along the axial direction of the positioning column 2.

[0029] In this way, after the clean water enters the sealing cavity 6, the first part of the clean water flows directly out of the sealing cavity 6, while the second part of the clean water first flows towards the inside of the sealing cavity 6, and then flows out of the sealing cavity 6 due to the water flow. The water flow of the second part of the clean water, which changes direction, can not only clean the inside of the sealing cavity 6, but also push the first part of the clean water, so that it can be sprayed out of the sealing cavity 6 quickly. This gives the sprayed clean water a certain water pressure, which can have a certain flushing effect on the slurry outside the sealing cavity 6.

[0030] Furthermore, the sealing medium delivery mechanism is used to pump clean water into the sealing cavity 6.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
