Description

Technical Field

[0001] The utility model belongs to the technical field of waste separation, and in particular relates to a rotary separator. Background Art

[0002] The widespread use of dust removal equipment is of great significance to energy conservation, emission reduction and environmental protection. However, most of the existing dust removal equipment is pulse or bag type dust collectors. For waste gas with high dust content, if it directly enters the pulse or bag type dust collector, it will greatly reduce the working efficiency. Now, cyclone dust collectors are mainly used to separate and extract different particles in polluted gas. The disadvantages of cyclone dust collectors are large pressure loss, large installation space, limited size of separated particles, and the need for a separate bottom bracket.

[0003] Therefore, it is necessary to design a separation device that can separate the mixed waste gas during the waste discharge process. Utility Model Content

The rotating shaft passes through the rotating hole and is rotatably connected to the lower shell, and the unloading plate is fixed on the rotating shaft.

[0008] In some embodiments, the shape of the filter screen fits the rotation trajectory of the discharge plate and is a semicircular arc.

[0009] In some embodiments, six unloading plates are evenly distributed with the rotating shaft as the axis, and each unloading plate includes a blade and a sealing plate. The blade and the sealing plate are fixed by a fixing plate. An L-shaped sealing strip is provided on the outer periphery of the sealing plate, and the sealing strip is fitted with the inner wall of the lower shell.

[0025] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0026] Example 1

[0027] Please refer to Figure 1-5The present embodiment provides a rotary separator for separating waste materials and waste gas, mainly comprising a lower shell 1, an upper shell 2, a discharge plate 3 and a filter screen 7. The lower shell 1 is open at both ends, and the lower end opening is a discharge port. In order to fit the rotation trajectory of the discharge plate 3, the inner wall shape of the lower shell 1 is set to be an arc. Rotation holes 11 are provided on both sides of the lower shell 1, and a bearing seat 15 is provided on the rotation hole 11. Due to the placement of the rotating shaft 14, a base 12 is provided next to one of the rotating holes 11, and a reducer 13 is fixed on the base 12. The output shaft of the reducer 13 is connected to the rotating shaft 14 through a transmission mechanism, and drives the rotating shaft 14 to rotate. The transmission mechanism is a commonly used transmission mechanism such as a coupling, a gear rack, and a synchronous belt. The discharge plate 3 is fixed on the rotating shaft 14 and rotates with the rotating shaft 14.

[0028] The upper shell 2 is a closed shell, with a feed port 4 at the top of the upper shell 2, an air outlet 5 at the side of the upper shell 2, a feed channel 6 connected to the feed port 4 on the lower shell 1, the connection between the feed port 4 and the feed channel 6 is sealed, and filters 7 are provided on both sides of the feed channel 6. The shape of the filter 7 fits the rotation trajectory of the discharge plate 3 and is a semicircular arc. In this embodiment, an exhaust fan is provided at the air outlet 5, and a negative pressure space is formed in the upper shell 2 on both sides of the feed channel 6 and above the discharge plate 3 under the action of the exhaust fan.

[0029] A V-shaped first reinforcing rib 35 is provided between two adjacent unloading plates 3, and a plurality of semicircular arc-shaped second reinforcing ribs 71 are provided on the filter screen 7. The provision of a plurality of reinforcing ribs improves the working strength of the rotary separator.

[0030] The working principle of this embodiment:

[0031] First, waste material containing exhaust gas enters from the feed port 4, passes through the feed channel 6 and enters the top of the discharge plate 3, and is discharged from the discharge port under the rotation of the discharge plate 3. The exhaust gas is extracted from the mesh of the filter screen 7 by the action of the exhaust fan, and then discharged from the air outlet 5, thereby realizing the separation of the exhaust gas and the waste material. Of course, in other embodiments, a pulse dust removal device can also be connected to the air outlet 5 to separate the dust particles in the exhaust gas again.

[0032] In the process of waste discharge, this embodiment forms a negative pressure space at the waste inlet, thereby collecting waste gas and reducing the pollution of the waste gas to the environment.

[0033] Example 2

[0034] Please refer to Figure 6-7 This embodiment is formed on the basis of the embodiment 1, and by further defining the specific structure of the discharge plate 3, the sealing performance of the negative pressure space is improved, and the exhaust gas discharge efficiency is further improved. Specifically:

[0035] In this embodiment, six unloading plates 3 are evenly distributed around the rotating shaft 14, forming a hexagonal star shape when viewed from the side. The six unloading plates 3 have the same structure. Each unloading plate 3 includes a blade 31, a sealing plate 32 and a fixing plate 33. Please refer to Figure 7 Several screw holes are opened on the blade 31, the sealing plate 32 and the fixing plate 33. The blade 31 is overlapped on one side of the sealing plate 32, and the fixing plate 33 is overlapped from the other side of the sealing plate 32. The blade 31, the sealing plate 32 and the fixing plate 33 are fixed by several screws to form the discharge plate 3. Except for the place connected with the rotating shaft 14, the sealing plate 32 is surrounded by an L-shaped sealing strip 34. During the rotation of the discharge plate 3, the sealing strip 34 is always in contact with the inner wall of the lower shell 1, which further improves the airtightness of the space above the discharge plate 3, thereby improving the efficiency of exhaust gas separation.
