Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a cyclone dust removal equipment. Background Art

[0002] Cyclone dust removal equipment is a device that uses the centrifugal force generated by the rotating airflow to separate dust from the airflow. It is mainly suitable for dust removal of non-fibrous and non-sticky dust. It has the advantages of simple structure, small size, no need for special auxiliary equipment, low cost, moderate resistance, no moving parts in the equipment, and easy operation and maintenance.

[0003] The working principle of the cyclone dust collector is to make the dust-laden airflow rotate, use centrifugal force to separate the dust particles from the airflow and capture them on the wall of the device, and then use gravity to make the dust particles fall into the ash hopper. In order to ensure the sealing and facilitate disassembly and maintenance, and prevent the dust-laden gas from leaking from the connection and affecting the dust removal effect, the cyclone dust collector and the ash hopper are connected by a flange and a gasket. However, due to the rotation of the airflow and pressure changes during the operation of the cyclone dust collector, the flange connection may become loose and leak, thereby affecting the dust removal effect. Therefore, it is necessary to design a cyclone dust removal equipment to solve the above-mentioned problems. Utility Model Content

[0004] Based on the above description, the present invention provides a cyclone dust removal device to solve the problem that the flange connection between the traditional cyclone dust collector and the ash hopper is prone to loosening, causing leakage and affecting the dust removal effect.

[0005] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a cyclone dust removal device, comprising a dust collector and an ash hopper, the dust collector and the ash hopper being connected by a flange, two openings being provided on the outer side of the dust collector, a metal ring being sleeved on the outer side of the dust collector, a through opening being provided through the surface of the metal ring, a hollow plate being provided in the through opening, an insertion rod being inserted between the inner side of the hollow plate and the opening, a connecting plate being welded to the outer side of the insertion rod, and a spring being provided between the connecting plate and the hollow plate.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, two openings 2 are provided on the outer side of the dust collector, and the diameter of the opening 2 is equal to that of the opening 1.

[0008] Furthermore, two baffles are connected to the surface of the metal ring and near the position inside the opening, and the sides of the two hollow plates that are away from each other are in contact with one side of the multiple baffles respectively, and the hollow plates are elliptical structures.

[0009] Furthermore, two openings three are provided on one side of the two hollow plates that are away from each other, and one side of the plurality of baffles is provided with a protruding rod that protrudes into the opening three.

[0010] Furthermore, the ends of the two insertion rods that are away from each other protrude to the outside of the metal ring respectively, and the ends of the two insertion rods that are away from each other are both connected to a grab plate.

[0011] Furthermore, the two hollow plates are connected to a sleeve on one side away from the other, and the two sleeves are protruded to the outside of the metal ring on the other side.

[0012] Furthermore, the inner diameter of the spring is adapted to the diameter of the insertion rod, and the spring is sleeved on the outside of the insertion rod.

[0013] Furthermore, two limiting grooves are vertically penetrated on the inner side of the metal ring, and two protrusions protruding into the limiting grooves are vertically connected to the outer side of the dust collector.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] 1. By opening an opening on the surface of the dust collector and arranging a metal ring, a hollow plate, an insert and a spring on the dust collector, the flange bolts between the dust collector and the ash hopper can be effectively restricted, thereby making the connection between the dust collector and the ash hopper tighter and avoiding the situation where the flange bolts at the connection become loose due to vibration generated during the operation of the dust collector, resulting in accidental leakage at the connection and affecting the dust removal effect.

[0016] 2. By setting a baffle on the metal ring and designing the hollow plate into an oval shape, the hollow plate and the metal ring can be disassembled, thereby facilitating the replacement of the spring in the later stage and avoiding the aging of the spring after long-term use, which makes replacement inconvenient.

[0028] In the present embodiment, the bottom surface of the metal ring 4 is in contact with the top surface of the nut, the insertion rod 6 is movably inserted between the hollow plate 5 and the opening one 11, and the position of the insertion rod 6 is limited by the spring 7 cooperating with the connecting plate 61 and the hollow plate 5, the insertion rod 6 can always be inserted into the opening one 11, and the bottom surface of the metal ring 4 can always be kept in contact with the top surface of the nut included in the flange 3, thereby achieving the limiting effect of the flange 3 and avoiding the accidental loosening of the flange 3 connection due to the vibration generated during the operation of the dust removal equipment.

[0029] As an optional embodiment, two openings 12 are opened on the outside of the dust collector 1, and the diameter of the opening 12 is equal to that of the opening 11. The ends of the two rods 6 that are away from each other protrude to the outside of the metal ring 4, and the ends of the two rods 6 that are away from each other are connected to a grab plate 62.

[0030] In this embodiment, when the flange 3 connection needs to be disassembled, the two grab plates 62 are grasped and pressure is applied to the side away from each other to pull. During the pulling process, the spring 7 is continuously compressed and contracted under the action of the connecting plate 61 until the ends of the two insertion rods 6 that are close to each other are away from the opening 11. Then, pressure is applied and slid upward to bring the insertion rod 6 and the opening 2 12 closer. Then, the grab plate 62 is slowly released, and the spring 7 rebounds, so that the insertion rod 6 is inserted into the opening 2 12, thereby realizing the position adjustment of the metal ring 4 and facilitating the operation of the flange 3 connection.
