一种用于热泵烘干设备的密封套及热泵烘干设备

Abstract

本实用新型涉及烘干设备技术领域，公开了一种用于热泵烘干设备的密封套，热泵烘干设备包括两器盒，两器盒的外壳上设有供冷媒管穿设的通道，密封套适配套设于冷媒管上，并与通道形成密封配合；其特征在于，密封套包括：具有弹性的密封套本体，密封套本体设有延其轴向贯穿的安装孔，用于容纳冷媒管；密封套本体上设有沿其径向延伸的切口，切口贯穿密封套本体的轴向全长，并连通安装孔与密封套本体的外周壁。上述用于热泵烘干设备的密封套，密封套本体上设有切口，可在冷媒管焊接后再套设于冷媒管上，避免了密封套因焊接时的高温而熔化变形的问题。

Claims

1. A sealing sleeve for a heat pump drying device, the heat pump drying device comprising two chambers, the outer shells of the two chambers having channels for refrigerant pipes to pass through, the sealing sleeve being adapted to be fitted onto the refrigerant pipes and forming a sealing fit with the channels; characterized in that, The sealing sleeve includes: The resilient sealing sleeve body has an axially extending mounting hole for accommodating the refrigerant pipe. The sealing sleeve body has a slit extending radially therethrough, the slit penetrating the entire axial length of the sealing sleeve body and connecting the mounting hole with the outer peripheral wall of the sealing sleeve body.

2. The sealing sleeve for a heat pump drying apparatus according to claim 1, characterized by, The sealing sleeve body has a bottom end face, which is a plane parallel to the axial direction of the sealing sleeve body.

3. The sealing sleeve for a heat pump drying apparatus according to claim 2, characterized by, The sealing sleeve body is a columnar body extending along its axial direction, and its radial cross-section is composed of a rectangular region and a semi-circular region connected to one side of the rectangular region; the other side of the rectangular region forms the bottom end face.

4. The sealing sleeve for a heat pump drying apparatus according to claim 3, characterized by, The cut extends through the bottom end face along the mounting hole.

5. A seal sleeve for a heat pump drying apparatus according to any one of claims 1 to 4, characterised in that, The outer peripheral wall of the sealing sleeve body is provided with a groove for positioning in conjunction with the protruding ribs on the inner wall of the channel on the two containers.

6. A seal for a heat pump drying apparatus according to any one of claims 1 to 4, wherein The sealing sleeve body has an abutment protrusion extending radially from the end face away from the two containers. The abutment protrusion is used to abut and limit the movement of the channel edge on the two containers.

7. A seal for a heat pump drying apparatus according to any one of claims 2 to 4, wherein The bottom end face of the sealing sleeve body is provided with a positioning notch, which is used to position and cooperate with the positioning protrusion on the inner wall of the channel.

8. The sealing sleeve for a heat pump drying apparatus according to claim 7, characterized by, The positioning notch extends along the axial direction of the sealing sleeve body in a direction away from the two containers, penetrating the sealing sleeve body.

9. A heat pump drying apparatus, characterized by, Includes the sealing sleeve as described in any one of claims 1-8.

10. The heat pump drying apparatus according to claim 9, characterized in that, The outer shell of the two-piece box includes a bottom shell and an upper shell.
