Abstract
Description
Technical Field
[0001] This utility model relates to the field of compaction machine technology, and more specifically, to a spiral degassing device for a dry compaction machine. Background Technology
[0002] Equipment that increases the density of solid materials by mechanically compacting them; typically, it employs a mechanical pressure system, such as a hydraulic device or a mechanical screw, to generate pressure. Taking a hydraulic dry compactor as an example, it uses a hydraulic cylinder to push a pressure head to apply pressure to the material. The pressure of the pressure head can be adjusted according to the properties of the material and the required degree of compaction, generally ranging from several megapascals to tens of megapascals; under pressure, the distance between particles gradually decreases.
[0003] In the application of existing compaction machines, the negative pressure inside the spiral degassing device is large, and the material is prone to block the end of the spiral degassing device with the airflow, affecting the operating efficiency of the spiral degassing device. It may even overflow through the connection of the bearings and other components of the spiral degassing device, resulting in increased material loss. Therefore, it is necessary to solve this problem. Utility Model Content

[0013] Furthermore, it also includes:
[0014] Two counterweights are placed on both sides of the housing and connected to the two ends of the rotating shaft.
[0015] The beneficial effect of adopting the above-mentioned further scheme is that the two counterweights, together with the rotating shaft and the guide plate, can regulate the material and airflow discharge rate.
[0016] Furthermore, it also includes:

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0028] like Figures 1 to 3 As shown, a screw degassing device for a dry compactor includes:
[0029] The housing 1 has a feed end 101 fixedly provided on one end and a discharge end 102 with an opening facing downwards on the other end.
[0030] A spiral shaft 2 is placed inside the housing 1, and the two ends of the spiral shaft 2 are rotatably connected to the two side walls of the housing 1, respectively.
[0031] A guide plate 3 is placed inside the housing 1 and is positioned above the discharge end 102. A rotating shaft 4 is fixedly connected to the upper end of the guide plate 3. The two ends of the rotating shaft 4 pass through the two side walls of the housing 1 and are rotatably connected to the housing 1.
[0032] In a specific application of this embodiment, the material is introduced into the feed end 101 of the casing 1. While the material is degassed, it is moved and conveyed under the action of the screw shaft 2. The airflow and material inside the casing 1 are discharged through the discharge end 102 under the guidance of the guide plate 3, so that the subsequent compaction of the material is more efficient and the density of the material is higher.
[0033] In addition, it can prevent materials from entering the connection between the screw shaft 2 and the casing 1, improve operating efficiency, prevent material overflow, and reduce material loss.
[0034] In the above embodiment, the guide plate 3 is provided with a downward-opening groove 301 in the middle, and the end of the spiral shaft 2 is located in the groove 301.
[0035] In practical applications, a groove 301 is arranged on the guide plate 3, and the spiral shaft 2 is located in the groove 301 as a shaft structure. The shaft part of the spiral shaft 2 is located in the groove 301, which avoids affecting the operating efficiency of the spiral shaft 2 and also ensures that the guide plate 3 guides the airflow and materials into the discharge end 102, maintaining the efficient guiding function of the guide plate 3.
[0036] The above embodiments also include:
[0037] Two counterweights 5 are placed on both sides of the housing 1 and connected to the two ends of the rotating shaft 4 respectively.
[0038] In practical applications, the two counterweights 5 are connected to the two ends of the rotating shaft 4 respectively. The two counterweights 5 can pull the rotating shaft 4, and the rotating shaft 4 drives the guide plate 3 to rotate, so that the guide plate 3 is at the optimal tilt angle, thereby allowing the airflow and material to be efficiently discharged through the guide plate 3. The two counterweights 5, together with the rotating shaft 4 and the guide plate 3, can regulate the discharge rate of material and airflow.
[0039] The above embodiments also include:
[0040] Motor 6, the output end of which is connected to the screw shaft 2, so that the output end of motor 6 drives the screw shaft 2 to rotate.
[0041] In practical applications, the motor 6 drives the screw shaft 2 to rotate, which enables the screw shaft 2 to operate efficiently and is easy to control.
[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
