Embodiment 1

[0047] like Figure 1 to Figure 9 As shown, a discharge door structure of a twin-shaft forced asphalt mixer, including a pot body liner 2 and a pot side liner 3 fixed on the inner side of the twin-shaft forced asphalt mixer pot shell 1, fixed on the The shaft end seal 7 on the end side wall of the twin-shaft forced asphalt mixture mixer and the rotary unloader arranged at the discharge port at the bottom of the twin-shaft forced asphalt mixer and matched with the shaft end seal 7 The material door, the lower part of the pot shell 1 of the twin-shaft forced asphalt mixer and the first waist hole 8 is opened near the discharge port, the side liner 3 of the pot is long and the double-shaft forced asphalt mixing Mixer pot shell 1, the pot side liner 3 is fixed on the twin-shaft forced asphalt mixer pot shell 1 by the first bolt 9 and can adjust the position along the first waist hole 8, the rotary discharge The door includes a material door main body, a material door liner 5 and ...

Embodiment 2

[0055] like Figure 10 to Figure 14 As shown, the difference between this embodiment and Embodiment 1 is that the number of the material door liner 5 arranged radially along the material door liner connecting plate 12 is one, and the shape of the material door liner 5 is arc-shaped. The outer surface of the material door liner connecting plate 12 is an arc surface, and the radius of the outer surface of the material door liner connecting plate 12 is equal to the radius of the inner surface of the material door liner 5 to achieve seamless fit; the shaft end The sealing member 7 is an end face seal ring, and a third waist hole 16 is opened on the end face seal ring, and the end face seal ring is fixed on the side of the twin-shaft forced asphalt mixer through the third bolt 13 and the third gasket 17. On the side wall of the end and can adjust the position along the third waist hole 16, the end face of the end face sealing ring and the end face of the material gate end plate 4 a...

Embodiment 3

[0057] like Figure 15 and Figure 16 As shown, the difference between this embodiment and Embodiment 1 is that: the shaft end seal 7 is a shaft end sealing plate, the second waist hole 7-1 is opened on the shaft end sealing plate, and the shaft end sealing plate It is fixed on the end side wall of the twin-shaft forced asphalt mixer through the second bolt 7-2 and the second gasket 7-3 and can adjust the position along the second waist hole 7-1, and the shaft end is sealed The seal plate cooperates with the material door lining plate 5 to realize the axial sealing of the discharge door, and the end surface of the shaft end sealing plate protrudes from the end surface of the material door lining plate 5 . During specific use, the installation position of the shaft end seal 7 can be adjusted according to the actual situation, and then the sealing gap between the shaft end seal 7 and the material door liner 5 can be adjusted, so that the shaft end seal 7 and the material door l...

Abstract

The invention discloses a discharge door structure of a double-horizontal-shaft forced-type bituminous mixture blender. The discharge door structure comprises pot body liner plates, pot side liner plates, a shaft end sealing element and a rotary type discharge door. The pot body liner plates and the pot side liner plates are fixed on the inner side of a pot shell of the blender. The shaft end sealing element is fixed on the sidewall of the end portion of the blender. The rotary type discharge door is arranged at a discharge port of the bottom of the blender. A first kidney-shaped hole is formed at the lower portion of the pot shell of the blender. The pot side liner plates are fixed on the pot shell of the blender. The rotary type discharge door comprises a door main body, door liner plates and door rotating shafts. The door main body is formed by two door end plates and a door liner plate connecting plate. The door liner plate connecting plate is respectively connected with the two door end plates. The door liner plates are fixed on the door liner plate connecting plate. The number of the door rotating shafts is two. The door rotating shafts are respectively connected with the upper portions of the two door end plates. The discharge door structure solves the problems that an existing discharge door device has larger stirring dead zones and stirring dead angles and is bad sealed, and compensation for wear clearances is not easy to adjust. Consequently, good axial sealing performance and good radial sealing performance of the discharge door can be guaranteed.

Description

technical field [0001] The invention relates to a discharge door structure, in particular to a discharge door structure of a twin-shaft forced asphalt mixture mixer. Background technique [0002] The twin-shaft forced asphalt mixer is currently the leading model widely used in asphalt mixing equipment. As one of the key components of the twin-shaft forced asphalt mixer, the discharge door device directly affects the production efficiency, mixing quality and operation reliability of the mixer. The discharge door device of the existing twin-shaft forced asphalt mixer is usually installed at the discharge port at the center of the bottom of the mixing pot, and the discharge port is opened and closed by the rotation of the discharge door device. This kind of rotary discharge door is mostly sealed by the good cooperation between the upper surface of the discharge door body and the lower surface of the bottom of the stirring pot body, but because of its relatively low sealing pos...
