Abstract
The utility model relates to a delivery mechanism in the fields of oil fields, construction, chemical industry and medical industry, in particular to a helical structure which is suitable for conveying solid particles in a pressed closed container. The helical structure comprises a drive shaft (1) which is arranged in a helical outer tube (3) and passes through a front end support (2) and a tail end support (10), a helical center shaft (7), a helical vane (8), and a discharge hole (11) and a feed inlet (12) which are arranged on the helical outer tube (3). The helical structure is characterized in that the drive shaft (1) and the center shaft (7) are connected through a universal joint (4), a corrugated pipe (5) is sealed outside the universal joint (4), the helical vane (8) and a reversevane (6) are connected on the center shaft (7), and a tail end support (9) is connected between the helical center shaft (7) and the tail end support (10). The helical structure has the characteristicof excellent seal effect, which is not easy to clamp a shaft when delivering solid particles in the pressed closed container.
Description
Technical field
The utility model relates to structure for conveying in oil field, building, chemical industry, the field of medicaments, is applicable to that particularly the load-transfer device densification closes a kind of helical structure of the particulate matter in the container.
Background technology
At present, conventional helical mainly is made up of blade, center shaft, transmission shaft, bearing, sealing, bearing and the spiral urceolus that has close import and export of size.It is directly used in the load-transfer device densification closes particulate matter in the container, cause problems such as an axle card, leakage easily.
Summary of the invention
Cause axle card easily in order to overcome the conventional helical structure, leak, carry the deficiency of problem such as not thorough, the utility model provides helical structure, and this helical structure has the advantages that to be difficult for axle card, good sealing effect when particulate matter in the container is closed in the load-transfer device densification.
The technical scheme that its technical matters that solves the utility model adopts is: design a kind of helical structure, it comprise in the spiral urceolus by front end support, transmission shaft, spiral center shaft, the helicallobe of end support and be arranged on discharging opening, inlet point on the spiral urceolus, it is characterized in that: connect by universal-joint between transmission shaft and the center shaft, the universal-joint outer gland sealing has bellows; On center shaft, be connected with helicallobe and backward vane; Be connected with end supports between spiral center shaft and the end support.
The bonded assembly helicallobe extends to discharge port end from the end support end on the described center shaft, and the bonded assembly backward vane extends to the universal-joint bellows end from discharge port end on the center shaft.
Described end supports supports for floating.
The beneficial effects of the utility model are: transmission shaft and center shaft adopt that universal-joint is connected, sylphon seal, have overcome the conventional helical structure when particulate matter in the container is closed in the load-transfer device densification, easily the problem of axle card, leakage.Set up backward vane near transmission shaft side place near the discharging opening, protected hermetically-sealed construction.Problems such as axle card that the conventional helical structure exists, leakage have been solved when particulate matter in the container is closed in the load-transfer device densification.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure principle chart of the present utility model.
Among the figure: 1, transmission shaft; 2, front end supports; 3, spiral urceolus; 4, universal-joint; 5, bellows; 6, backward vane; 7, spiral center shaft; 8, helicallobe; 9, end supports; 10, end support; 11, discharging opening; 12, inlet point.
The specific embodiment
As shown in Figure 1, this helical structure comprise in the spiral urceolus 3 by front end support 2, transmission shaft 1, spiral center shaft 7, the helicallobe 8 of end support 10 and be arranged on discharging opening 11, inlet point 12 on the spiral urceolus 3, wherein, connect by universal-joint 4 between transmission shaft 1 and the center shaft 7, universal-joint 4 outer gland sealings have bellows 5; On center shaft 7, be connected with helicallobe 8 and backward vane 6; Be connected with end supports 9 between spiral center shaft 7 and the end support 10.
The wide mouthful inlet point 12 of material by spiral urceolus 3 that the densification of the utility model band is closed in the container can enter in the spiral urceolus 3 fully.The material that enters in the spiral urceolus 3 is exported from discharging opening 11 under the effect of helicallobe 8.When in spiral installation or working process, when off-centre or swing appear in spiral center shaft 7, so the universal-joint 4 between spiral center shaft 7 and transmission shaft 1 will reduce eccentricity of central axis or swing seals the influence that causes to transmission shaft.And this helical structure end supports 9 supports for floating, and can improve the tail sealing structure operating mode.
Claims (3)
1. helical structure, it comprises in the spiral urceolus (3) supports transmission shaft (1), spiral center shaft (7), the helicallobe (8) of (2), end support (10) by front end and is arranged on discharging opening (11), inlet point (12) on the spiral urceolus (3), it is characterized in that: connect by universal-joint (4) between transmission shaft (1) and the center shaft (7), universal-joint (4) outer gland sealing has bellows (5); On center shaft (7), be connected with helicallobe (8) and backward vane (6); Be connected with end supports (9) between spiral center shaft (7) and the end support (10).
