Technical Field
[0001] The utility model relates to the technical field of powder storage, in particular to a dust-proof head for a silo. Background Art
[0002] When storing calcium oxide and the like, in order to avoid the powder spreading outwards and polluting the environment, a dust-proof bag is usually arranged at the upper end of the storage tank. The dust-proof bag can avoid the escape of dust during the feeding process. However, the dust-proof ability of the dust-proof bag is limited, and with the passage of time, the pores of the dust-proof bag are easily blocked by dust, and then the problem of poor exhaust occurs. Content of the Utility Model
[0003] The utility model provides a dust-proof head for a silo to solve the deficiencies of the above-mentioned prior art, solve the problems of poor dust-proof ability of the dust-proof bag and easy blockage of the dust-proof bag by powder, and has strong practicability.
[0004] In order to achieve the purpose of the utility model, the following technology is proposed:
[0005] A dust-proof head for a silo includes a collection tank with an upper opening. An air outlet pipe is formed at the bottom of the collection tank. The upper end of the air outlet pipe is communicated with a pipe head. A support ring is arranged at the bottom of the collection tank. A storage tank is placed on the support ring. An accommodation ring groove is formed at the upper end of the storage tank with an opening. Through the arranged air outlet pipe, dust can be discharged outwards driven by air. The collection tank can collect the dust generated during the exhaust process. The accommodation ring groove is used for collecting the first layer of powder inside, thus improving the powder storage capacity. An inner ring is arranged in the storage tank. A plurality of outer support plates are arranged on the inner ring. An inner dust-proof cloth bag is sleeved outside the outer support plates. The lower end of the inner dust-proof cloth bag is arranged at the bottom of the accommodation ring groove. The inner dust-proof cloth bag can block the escape of dust and form the first line of defense against dust escape. An outer ring is arranged outside the storage tank. A plurality of spreading plates are arranged at the upper end of the outer ring. The outer ring is located outside the inner ring. An outer dust-proof cloth bag is sleeved outside the spreading plates. The lower end of the outer dust-proof cloth bag is open, and the lower end of the outer dust-proof cloth bag is sleeved on the upper end of the storage tank. The outer dust-proof cloth bag forms the second line of defense to further block the escape of dust. An exhaust tank is arranged at the upper end of the collection tank. A plurality of exhaust holes are formed in the exhaust tank, which are convenient for the discharge of air.
[0006] Further, when air is discharged, in order to make part of the dust settle naturally in the collection tank, the air outlet pipe is in a conical structure, and the upper end of the air outlet pipe is the small end.
[0007] Further, in order to facilitate the later cleaning of the collected powder, the inner circumference of the support ring is a conical surface, and the lower end of the conical surface is the small end.
[0008] Furthermore, in order to prevent dust from escaping outward, the outer support plate is arranged in a V-shaped structure, with the narrow side of the outer support plate facing outward.
[0009] Furthermore, in order to facilitate the discharge of air and reduce the energy of dust dissipating outwards through friction resistance, etc., the support plate is arranged in a V-shaped structure, and the narrow side of the support plate faces inward.
[0010] Furthermore, in order to ensure the sealing effect of the outer dust bag, an outer convex edge is provided on the outer periphery of the upper end of the storage tank, and the lower end of the outer dust bag is sleeved on the lower side of the outer convex edge.
[0011] Furthermore, in order to improve the stability and sealing effect of the outer dust bag after installation, a pressure ring is installed on the storage tank, and a plurality of protrusions are provided on the lower wall of the pressure ring. A U-shaped groove is opened on the outer wall of the protrusion. A pressure rod is provided in the U-shaped groove, and a concave part is provided on the pressure rod. A holding rod is provided at the outer end of the concave part. A connecting protrusion is rotatably provided on the concave part, and the connecting protrusion is provided on the outer wall of the storage tank.
[0012] The advantages of the above technical solution are:
[0013] The utility model facilitates the collection of dust and can improve the dust holding capacity and blocking capacity, thereby further reducing the pollution to the environment. BRIEF DESCRIPTION OF THE DRAWINGS
