Description

Technical Field

[0001] The utility model relates to a mobile particle bed dust collector, in particular to a hydraulic device of a release valve of the mobile particle bed dust collector. Background Art

[0002] At present, mobile particle bed dust collectors have been applied to the field of high-temperature raw coal gas dust removal technology in pulverized coal distillation devices. Mobile particle bed dust collectors achieve efficient dust removal by moving filter media in reverse contact with raw coal gas. However, when the filter material unloading device of the mobile particle bed dust collector fails, the filter material no longer moves, and the de-heated filter material cannot reach the filter section, causing the filter material temperature in the filter section to continue to drop. When the high-temperature raw coal gas encounters filter material with a temperature below 350°C, the coal tar in the high-temperature raw coal gas will gradually precipitate. If the high-temperature raw coal gas cannot be released in time, the filter material will become compacted and cause production accidents. The emergency relief valve of the mobile particle bed dust collector is mostly an electric valve. When a power outage occurs, it cannot be opened in time, which will also cause production accidents.

[0003] Valves driven by hydraulic devices have become the first choice for emergency relief valves in accident conditions, but the hydraulic station also needs electricity to start the hydraulic oil pump to open the valve, and power outages can also cause the hydraulic device to lose its function. Utility Model Content

[0004] The utility model aims to provide a release valve hydraulic device with reasonable structural design, low production and processing cost, safe and reliable use, convenient operation and maintenance, and capable of solving production accident problems such as the failure of a mobile granular bed dust collector to open the release valve in a power outage accident state, resulting in the compaction of filter material in the mobile granular bed dust collector.

[0005] The utility model discloses a hydraulic device of a release valve of a mobile particle bed dust collector, comprising an oil tank, a hydraulic oil pump is installed in the oil tank, a main oil inlet pipe is connected to the hydraulic oil pump, the main oil inlet pipe is connected to a release accumulator oil pipe I, the release accumulator oil pipe is connected to the release accumulator; the main oil inlet pipe is connected to a pressure-maintaining accumulator oil pipe, the pressure-maintaining accumulator oil pipe is connected to the pressure-maintaining accumulator; the main oil inlet pipe is connected to a release valve cylinder circuit oil pipe, the release valve cylinder circuit oil pipe is connected to the release valve cylinder, a check valve is installed on the main oil inlet pipe, a release valve cylinder circuit is connected in parallel to the release valve cylinder circuit oil pipe, an output end of the release valve cylinder circuit is connected to an oil return pipe, and an oil return filter is connected to the oil return pipe.

[0006] An electromagnetic reversing valve is installed on the release valve oil cylinder circuit.

[0007] When operating the relief valve under normal use, it is only necessary to start the hydraulic oil pump. At this time, the hydraulic oil enters the relief valve cylinder circuit, and the electromagnetic reversing valve is used to control the retraction and advancement of the piston in the relief valve cylinder, thereby realizing the opening and closing of the relief valve; the relief accumulator and the pressure-maintaining accumulator are set. When the relief valve is operated, the hydraulic oil enters the relief accumulator and the pressure-maintaining accumulator through the relief accumulator oil pipe and the pressure-maintaining accumulator oil pipe, so as to store the hydraulic oil, thereby reducing consumption and saving energy.

[0008] The oil return pipeline is connected with the oil drain pipe, the oil drain pipe is connected with the oil pipe of the relief valve cylinder, and an emergency manual valve I is installed on the oil drain pipe.

[0009] The release accumulator oil pipe I and the pressure-maintaining accumulator oil pipe are respectively equipped with high-pressure relief valves.

[0010] The high-pressure relief valve is installed to maintain the pressure in the release accumulator and the pressure-maintaining accumulator, so that the pressure remains stable and ensures that the pressure does not exceed the specified range, thereby preventing accidents.

[0011] The release accumulator oil pipe I is connected to the release accumulator oil pipe II, the release accumulator oil pipe II is connected to the oil pipe of the release valve cylinder, and an emergency manual valve II is installed on the release accumulator oil pipe II.

[0012] When a power outage or hydraulic oil pump failure occurs and the hydraulic oil pump cannot be started, immediately open the emergency manual valve and the emergency manual valve, and the stored hydraulic oil in the release accumulator enters the release valve cylinder cavity through the release accumulator oil pipe Ⅰ and the release accumulator oil pipe Ⅱ, pushing the piston to open the release valve, thereby avoiding accidents.

[0013] The pressure-maintaining accumulator is connected to the oil pipe of the release valve oil cylinder through a pressure-maintaining oil pipe, and a solenoid valve is installed on the pressure-maintaining oil pipe.

[0014] The purpose of the pressure-maintaining accumulator is to provide a stable and lasting pressure to the discharge valve cylinder cavity to prevent the discharge valve cylinder cavity from losing pressure and causing the valve to open accidentally; when the hydraulic oil pump stops, the solenoid valve is energized to open, and the hydraulic oil in the pressure-maintaining accumulator enters the discharge valve cylinder cavity. When the hydraulic oil pump starts, the solenoid valve loses power and closes, cutting off the pressure-maintaining accumulator.

[0015] A pressure gauge, a temperature level gauge and a radiator are installed on the surface of the oil tank.

[0016] Beneficial effects of the utility model:

[0017] 1) The set release accumulator and pressure-maintaining accumulator, when operating the release valve, the hydraulic oil enters the release accumulator and the pressure-maintaining accumulator through the release accumulator oil pipe and the pressure-maintaining accumulator oil pipe, which can store the hydraulic oil and play a role in reducing consumption and energy saving; when the release valve is operated normally, the hydraulic oil pump is started, and the hydraulic oil enters the release valve cylinder circuit, and the electromagnetic reversing valve controls the retraction and advancement of the piston in the release valve cylinder, thereby realizing the opening and closing of the release valve, and the operation is safe and reliable.

[0018] 2) When a power outage or hydraulic oil pump failure occurs and the hydraulic oil pump cannot be started, the emergency manual valve and the emergency manual valve are immediately opened for the set release accumulator. The stored hydraulic oil in the release accumulator enters the release valve cylinder cavity through the release accumulator oil pipe I and the release accumulator oil pipe II, pushing the piston to open the release valve, thereby avoiding accidents and ensuring safety and reliability.

[0019] 3) The purpose of the pressure-maintaining accumulator is to provide a stable and lasting pressure to the discharge valve cylinder cavity to prevent the valve from accidentally opening due to pressure loss in the discharge valve cylinder cavity. When the hydraulic oil pump stops, the solenoid valve is energized to open, and the hydraulic oil in the pressure-maintaining accumulator enters the discharge valve cylinder cavity. When the hydraulic oil pump starts, the solenoid valve loses power and closes, cutting off the pressure-maintaining accumulator.

[0020] 4) The device has a reasonable structural design, low production and processing costs, safe and reliable use, and easy operation and maintenance. It can solve production accidents such as the mobile granular bed dust collector filter material compaction caused by the failure of the discharge valve to open during a power outage, and is worthy of widespread promotion and application.
