Description

Technical Field

[0001] This utility model relates to the field of electrical automation technology, and in particular to a sealing cover for a degassing device with waste gas collection. Background Technology

[0002] In industries such as metallurgy, chemical engineering, and semiconductor manufacturing, degassing devices are widely used for degassing molten metal or chemical solutions. These processes are often accompanied by the release of high-temperature toxic waste gases, which need to be collected and treated in an environmentally friendly manner through a sealed enclosure. A sealed enclosure for a degassing device with waste gas collection has become a core piece of equipment to ensure production safety and environmental compliance, and its performance directly affects the waste gas collection efficiency and subsequent purification effect.

[0003] Current mainstream technology adopts a fixed gas collection hood structure, which is usually composed of a metal hood, fixed air ducts and an external purification system. The exhaust gas is introduced into the purification unit through the air duct by the constant suction generated by the negative pressure fan. Some equipment adds louvered baffles at the air duct inlet. The local airflow is controlled by manually adjusting the angle of a single baffle. The purification process often uses an independent cooling tower connected in series with the filter device. The coolant reduces the temperature of the exhaust gas through an external circulation pipeline, and then the filter material intercepts particulate matter.

[0004] However, the existing air collection hood has significant defects in its airflow guiding structure. The louvered baffles need to be adjusted individually, which is cumbersome and makes it difficult to achieve synchronous operation of multiple baffles. Furthermore, the baffles lack an effective positioning mechanism, and the angle is easily offset by airflow impact or equipment vibration. This makes it difficult to match the exhaust gas collection section with the dynamically changing emission intensity. This defect directly causes exhaust gas to escape under high flow conditions and energy waste under low flow conditions, reducing the overall collection efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sealing cover for a degassing device with exhaust gas collection, which aims to improve the problem that the exhaust gas collection cross section is difficult to match with the dynamically changing emission intensity.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sealing cover for a degassing device with waste gas collection, comprising a support column, a support arm slidably connected to the outer wall of the support column, a sealing cover fixedly connected to the lower surface of the support arm, an adjustment component provided on the outer wall of the support arm, a cooling component provided inside the sealing cover, a degassing component provided inside the sealing cover, and a cooling box provided outside the support column.

[0007] The adjustment assembly includes a vent box and wind deflectors. The outer wall of the vent box is fixedly connected to one side of the outer wall of the support arm. Air collection pipes are fixedly connected to both sides of the outer wall of the vent box. The outer walls of multiple wind deflectors are rotatably connected to the inner wall of the vent box. The outer walls of multiple wind deflectors are connected by connecting rods. A handle is fixedly connected to one end of each wind deflector. The handle is located on the outer wall of the vent box. A ball bearing is installed inside the handle. Multiple grooves are formed on the outer wall of the vent box. The ball bearing is located inside the grooves.

[0008] Furthermore, the cooling assembly includes a cooling pipe disposed inside the sealing cover and on the outer wall of the gas collecting pipe. One end of the cooling pipe is fixedly connected to a diverter pipe, and a water pump is fixedly connected to the lower surface of the diverter pipe. The output end of the water pump is fixedly connected to the other end of the cooling pipe.

[0009] Furthermore, a filter plate is installed inside the cooling box, and a fan is fixedly connected to the outer wall of the cooling box.

[0010] Furthermore, one end of one of the gas collecting pipes is fixedly connected to the inner wall of the sealing cover, and the other end of the gas collecting pipe is fixedly connected to the inside of the cooling box.

[0011] Furthermore, a spring is provided inside the handle, with one end of the spring fixedly connected to the inner wall of the handle and the other end of the spring fixedly connected to the outer wall of the ball bearing.

[0012] Furthermore, the outer wall of the support column is provided with two sprockets, which are connected by a chain. A motor is installed inside the support column, and the output end of the motor is fixedly connected to the inner wall of one of the sprockets. The inner wall of the support arm is fixedly connected to the outer wall of the chain on one side.

[0013] Furthermore, the degassing assembly includes a stirring blade, one end of which is rotatably connected to the inner wall of the support arm through the sealing cover.

[0014] Furthermore, a second motor is installed inside the support arm, and the output end of the second motor is fixedly connected to one end of the stirring blade.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the adjustment component, by setting up a ventilation box, a gas collection pipe and a rotatable baffle, can rotate the handle according to the actual exhaust gas emission situation, drive the connecting rod to make multiple baffles rotate simultaneously, control the exhaust gas collection efficiency, and combine the elastic locking design of ball, spring and groove to effectively resist the displacement caused by airflow impact or equipment vibration, ensure the baffle angle is stably locked, and avoid the escape of high flow exhaust gas and the waste of low flow energy.

[0017] 2. In this utility model, the water pump causes the coolant to enter the cooling pipe from the distribution pipe, absorb the heat of the exhaust gas and return to the cooling pipe. The filter plate can filter the exhaust gas sent from the air collection pipe. The filter plate and the distribution pipe are set in the same cooling box, which saves the space occupied by the independent cooling tower and the filter device. Only one fan is needed to meet the functions of cooling and filtering exhaust gas, which greatly reduces the complexity of the equipment and energy consumption. Attached Figure Description
