Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to a dust catcher. Background Art

[0002] It is well known that a large amount of viscous gas with sparks will be generated when factories are smelting or melting metals. These gases will also carry a large amount of dust. If they are directly discharged, they will pollute the environment and do not meet environmental protection requirements. Therefore, it is necessary to use a dust collector to treat the viscous gas with sparks; most of the existing dust collectors allow the viscous gas with sparks to contact and collide with the mesh plate in the dust collector box to eliminate the sparks and redirect the dust in the gas to settle; after a period of time, dust will adhere to the surface of the mesh plate and cause blockage, and the mesh plate needs to be frequently disassembled for cleaning, which has a short service life and cumbersome maintenance operations; the above defects are problems that need to be urgently solved by technical personnel in this field. Utility Model Content

[0012] The utility model discloses a dust collector with a simple structure and a long service life. A plurality of filter plates in a folding shape are arranged at intervals from the air inlet pipe to the air outlet in the box body. When in use, viscous gas with sparks enters the box body along the air inlet pipe, and the viscous gas with sparks returns and collides with the filter plate, so that the dust in the gas changes direction and settles, and the sparks in the gas are eliminated at the same time.

[0019] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0020] Embodiment 1, in combination with Figures 1 to 4, a dust collector comprises a box body 1, a filter plate 2 and a cleaning pipe 3; one side of the box body 1 is provided with an air inlet pipe 4, and the other side is provided with an air outlet, and the bottom of the box body 1 is connected to a drop hopper 5 for collecting dust; a plurality of filter plates 2 in a hinged shape are arranged at intervals from the air inlet pipe 4 to the air outlet in the box body 1, and a plurality of through holes are arranged in an array on the plate surface of the filter plate 2, and the through holes on the plate surfaces of two adjacent filter plates 2 are arranged in a staggered manner to prevent airflow from directly flowing through the through holes on the plate surfaces of two adjacent filter plates 2; when in use, the viscous gas with sparks enters the box body 1 along the air inlet pipe 4, and the viscous gas with sparks is returned and collides with the filter plate 2, so that the dust in the gas is deflected and settled, and the sparks in the gas are eliminated at the same time, and the settled dust falls into the drop hopper 5, and is collected and processed uniformly;

[0021] A plurality of cleaning pipes 3 are arranged at intervals on one side of the surface of the filter plate 2 in the box body 1, and a plurality of purge holes for cleaning the through holes on the surface of the filter plate 2 are arranged at intervals from top to bottom on the body of the cleaning pipe 3; a gas cylinder 6 is provided on the top of the box body 1, and the gas cylinder 6 is connected to the cleaning pipe 3 via a pulse valve 7. After the filter plate 2 has worked for a period of time, the through holes on the surface of the plate begin to be blocked. The operator can connect the gas cylinder 6 to a high-pressure gas source, and after the pressure in the gas cylinder 6 reaches a set value, the pulse valve 7 is controlled to open and close, so that the cleaning pipe 3 is connected to the high-pressure gas. The high-pressure gas is blown from the purge hole to the filter plate 2 in a pulse form, so that the through holes on the surface of the filter plate 2 are unobstructed again, thereby effectively improving the service life of the filter plate 2.

[0022] Embodiment 2, in combination with Figures 1 to 4 , a dust catcher, which is different from the embodiment 1 in that, on the basis of the embodiment 1, the four corner ends of the filter plate 2 are elastically connected to the inner wall of the box body 1 through springs, and after the cleaning pipe 3 is connected to the high-pressure gas, the high-pressure gas is blown from the cleaning hole to the filter plate 2 in the form of pulses, which can make the filter plate 2 vibrate, so that the dust adsorbed on the surface of the filter plate 2 falls off, and the cleaning effect of the filter plate 2 is further improved;

[0023] The cleaning pipe 3 is securely connected to the housing 1 via a bracket, which can prevent the cleaning pipe 3 from vibrating when high-pressure pulse gas is passed through it, and prevent accidental breakage due to metal fatigue caused by long-term vibration. A vibration motor 8 is provided on the side wall of the drop hopper 5, which can be started when collecting dust in the drop hopper 5, to prevent dust from accumulating and clogging in the drop hopper 5, resulting in incomplete discharge.

[0024] Embodiment 3, in combination with Figures 1 to 5, a dust collector, based on embodiment 1 or 2, the air inlet pipe 4 has a trumpet-shaped structure, which can slow down the flow rate of the airflow entering the box body 1, so that the viscous gas with sparks can fully collide with the filter plate 2, thereby improving the dust capture effect; the air inlet pipe 4 is provided with a spiral blade for making the intake airflow produce a swirl, that is, the viscous gas with sparks produces a swirl under the guidance of the spiral blades, further increasing the probability of the viscous gas with sparks colliding with the filter plate 2, thereby improving the dust capture effect.
