Abstract
Description
Technical Field
[0001] This utility model relates to a centrifuge, and more particularly to an exhaust device for a centrifuge. Background Technology
[0002] A centrifuge is a device that uses centrifugal force to separate the components of a mixture of liquids and solid particles or liquids and liquids. In the pharmaceutical industry, centrifuges are sometimes used to filter substances such as acids or organic solvents, which may produce harmful gases. The volatilization of these harmful gases can pollute the surrounding environment and endanger the health of workers. Traditional centrifuges create a sealed space when the cover is fastened to the centrifuge drum. In actual operation, leakage is mainly prevented by sealing rings. If the sealing rings malfunction, leakage can easily occur.
[0003] In existing technologies, holes are usually made in the centrifuge cover to guide the gas out through the output pipe. However, since the gas is also affected by centrifugal force, it diffuses in a spiral direction in all directions inside the centrifuge, and it is not easy to be discharged through the output pipe due to air pressure issues. Summary of the Invention
[0004] The purpose of this invention is to provide an exhaust device for centrifuges that can guide the emission and treatment of harmful gases.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A centrifuge exhaust device is provided, comprising a centrifuge housing, a centrifuge drum fixedly disposed inside the centrifuge housing, multiple exhaust pipes fixedly connected to the outer wall of the centrifuge drum near the drum opening, a baffle and a support plate respectively disposed between the centrifuge drum and the centrifuge housing, multiple gas filters fixedly disposed on the support plate, an air pump fixedly disposed on the bottom plate of the centrifuge housing, an exhaust pipe fixedly connected to the output end of the air pump, an exhaust port opened on one side of the centrifuge housing, a partition fixedly disposed near the inner side of the exhaust port, the exhaust pipe passing through the partition, an air outlet filter fixedly disposed in the middle of the exhaust port, and multiple mounting shafts rotatably connected near the outer side of the exhaust port, with guide plates fixedly connected to each of the multiple mounting shafts. Optionally, a motor is fixedly connected to the bottom of the centrifuge tank, and a rotating frame is rotatably connected to the middle of the bottom plate of the centrifuge tank. The output end of the motor is fixedly connected to the lower end of the rotating shaft of the rotating frame.
[0006] Optionally, the support plate is fixedly connected between the centrifuge shell and the centrifuge barrel, the baffle is movably disposed between the centrifuge shell and the centrifuge barrel, and the baffle (2) is disposed at the upper end of the support plate (7). A plurality of gas filters are evenly distributed on the support plate, and all of the gas filters are HEPA filters.
[0007] Optionally, a cover is rotatably connected to the upper end of the centrifuge shell, and an air inlet filter is fixedly installed in the air hole in the middle of the cover.
[0008] Optionally, the centrifuge shell has a mounting groove at its rear end, and the rear ends of the plurality of mounting shafts pass through the mounting groove and are fixedly connected to gears. A toothed plate is provided between the gears and the inner wall of the mounting shafts, and the gears and toothed plates mesh. A lifting rope is fixedly connected to the upper end of the toothed plate, and an electric telescopic rod is fixedly connected to the inner wall of the centrifuge shell. The other end of the lifting rope is fixedly connected to the output end of the electric telescopic rod.
[0009] Optionally, a pulley one is rotatably connected near the upper end of the mounting groove, and a pulley two is rotatably connected to the inner wall of the centrifuge shell. The suspension rope passes through the upper ends of pulley one and pulley two in sequence.
[0010] Optionally, a guide rod is fixedly connected to one side of the bottom of the mounting groove, and a mounting plate is slidably connected to the outer wall of the guide rod. The mounting plate is fixedly connected to the outer wall of the toothed plate, and a spring is fixedly connected between the mounting plate and the inner wall of the mounting groove. The spring is movably sleeved on the outer wall of the guide rod.
[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model is equipped with a baffle, centrifuge bucket, exhaust pipe, support plate, gas filter, air pump, exhaust pipe, exhaust port, air outlet filter, and partition. During operation, the air pump guides the harmful gases in the centrifuge bucket through the exhaust pipe and filters them by adsorbing aerosols carrying bacteria and viruses through the gas filter. Then, the air pump blows the filtered gas through the exhaust pipe to the activated carbon filter, where the volatile organic compounds are adsorbed and discharged through the exhaust port. During operation, the centrifuge shell is kept under negative pressure to prevent harmful gases from leaking out.
[0012] 2. This utility model includes an installation shaft, guide plates, installation grooves, gears, toothed plates, an installation plate, a guide rod, a spring, a suspension rope, pulley one, pulley two, and an electric telescopic rod. With the connection and cooperation of the suspension rope, pulley one, and pulley two, the electric telescopic rod works to drive the toothed plates to move up and down in coordination with the extension and retraction of the spring. Thus, by utilizing the meshing relationship between the toothed plates and the gears, the installation shaft controls the simultaneous opening and closing of multiple guide plates. When the device is not in use, the guide plates are closed, which protects the air outlet filter and prevents dust from entering. Attached Figure Description
