Description

Technical Field

[0001] This utility model relates to the field of pulverized coal conveying technology, and in particular to a device for checking blockages in coal conveying pipes of lime kilns. Background Technology

[0002] In the slaking process of quicklime, the addition of pulverized coal is a crucial step. Multiple pipelines are arranged around the lime kiln to transport the pulverized coal into the kiln to support the slaking reaction of quicklime. However, in actual operation, these pipelines sometimes become blocked, affecting the efficiency of pulverized coal transport and the normal operation of the lime kiln. Traditional detection methods rely on pressure gauges to monitor pressure changes in the pipelines. However, this method has certain limitations in practical applications. Pressure gauges sometimes cannot accurately reflect the pressure changes inside the pipeline, leading to inaccurate readings and making it impossible to pinpoint which specific pipeline is blocked. This makes troubleshooting and timely handling difficult, affecting production efficiency and safety. Utility Model Content

[0003] To overcome the shortcomings of the existing devices mentioned above, this utility model provides a device for checking blockages in coal conveying pipes of lime kilns, which can quickly check blocked pipes.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a lime kiln coal conveying pipe blockage inspection device, including a coal conveying hose and a kiln inlet pipe, one end of the coal conveying hose being connected to the kiln inlet pipe; a tee pipe is connected to the coal conveying hose, a coal injection pipe is connected to the tee pipe, a detection ball valve is provided on the coal injection pipe, and a handle for controlling the switch of the detection ball valve is provided on the detection ball valve.

[0005] Preferably, a transparent cover is provided at the position of the tee on the coal conveying hose, and a small door that can be opened is provided at the top of the cover at the position corresponding to the handle; a removable collection box is provided at the bottom of the cover; and a filter is provided at the top of the coal injection pipe.

[0006] Preferably, the kiln inlet pipe is equipped with an air volume regulating butterfly valve and a spray gun cooling air check valve.

[0007] The beneficial effects of this utility model are that by opening and closing the detection ball valve, it is possible to intuitively check whether the coal conveying hose is blocked, which improves the inspection efficiency and eliminates the need to stop the kiln for inspection, thereby improving the operating rate of the lime kiln equipment; through the setting of the cover and filter, it is possible to effectively prevent coal powder from polluting the environment when it is sprayed out and ensure the safety of operators.

[0011] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0012] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0013] according to Figure 1 As shown, a coal conveying pipe blockage inspection device for a lime kiln includes a coal conveying hose 1 and a kiln inlet pipe 2. One end of the coal conveying hose 1 is connected to the kiln inlet pipe 2. A tee pipe 3 is connected to the coal conveying hose 1, and a coal injection pipe 4 is connected to the tee pipe 3. A detection ball valve 5 is installed on the coal injection pipe 4, and a handle 51 is installed on the detection ball valve 5 to control its opening and closing. By cooperating with the ball valve 5, the coal injection pipe 4 can be used to check whether the coal conveying hose 1 is blocked without blocking the flow of coal powder. The handle 51 is used to control the opening and closing of the ball valve 3 to observe whether coal powder is sprayed out, thereby determining whether the coal conveying pipe 1 is blocked.

[0014] A transparent cover 6 is also provided at the position of the tee pipe 3 on the coal conveying hose 1. The transparent cover 4 allows the operator to observe the inside. A small door 61 that can be opened is provided at the top of the cover 6 at the position corresponding to the handle 51, which is convenient for the operator to operate the handle 51. A removable collection box 62 is provided at the bottom of the cover 6. The cover 6 prevents the sprayed coal powder from falling into the surrounding environment and causing pollution. At the same time, it guides the coal powder to fall into the collection box 62 at the bottom for cleaning and recycling, preventing resource waste. A filter 7 is provided at the top of the coal injection pipe 4, which can filter the sprayed coal powder and effectively control the spraying of coal powder.

[0015] The kiln inlet pipe 2 is equipped with an air volume regulating butterfly valve 21 and a spray gun cooling air check valve 22.

[0016] In practical operation, the operator first opens the small door 61 on the cover 6. After opening the small door, the operator then opens the detection ball valve 5 by rotating the handle 51. After opening the detection ball valve 5, the coal powder will be sprayed out from the coal injection pipe 4 under pressure. If coal powder is sprayed out, it means that the coal conveying hose 1 is not blocked. If no coal powder is sprayed out, it means that the coal conveying hose 1 is blocked. When the coal powder is sprayed out, the cover 6 can effectively block and guide the coal powder to prevent it from flying into the surrounding environment. Then it falls into the collection box 62 for collection. The sprayed coal powder can be easily recovered through the collection box 62.

[0017] This design is ingenious. By opening and closing the detection ball valve 5, it is possible to directly check whether the coal conveying hose 1 is blocked, which improves the inspection efficiency and eliminates the need to stop the kiln for inspection, thereby improving the operating rate of the lime kiln equipment. The installation of the cover 6 and filter 7 can effectively prevent coal powder from polluting the environment when it is sprayed out and ensure the safety of operators.

[0018] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
