Abstract
The utility model relates to a support for a spiral blade of a spiral classifier. The support comprises steel channels (1) and angle iron (3), wherein one end of each steel channel (1) is fixedly connected with a shroud ring (2); the other end of each steel channel (1) is fixedly connected with the blade (4); the steel channels (1) are uniformly arranged between the shroud ring (2) and the blade (4) at intervals; and the angle iron (3) is fixedly arranged between any two steel channels (1). The support is concise in structure and low in manufacturing cost.
Description
Technical field
The utility model relates to mechanical manufacturing field, relates in particular to a kind of support of spiral classifier helical blade.
Background technology
In the prior art, the support of spiral classifier helical blade, especially diameter mostly adopt 14 millimeters thick steel plates to support more than 1000 millimeters, perforate on steel plate, Yi Bian directly be welded on the main shaft pipe or be welded on shroud ring, another side is welded on blade.When steel plate directly is welded on the main shaft pipe, can cause the main shaft tube bending in production process; Steel plate is welded together in angle bar in addition, directly cuts out triangle on steel plate, and this can cause larger waste, as directly not cutting on steel plate, will again weld triangle, and comparison is time-consuming.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of support of spiral classifier helical blade, and low cost of manufacture is simple for structure, and intensity is high.
For solving the problems of the technologies described above, the utility model provides a kind of support of spiral classifier helical blade, and described support comprises channel-section steel and angle bar, and channel-section steel one end is fixedly connected with shroud ring, the other end is fixedly connected with blade, and channel-section steel is disposed in an evenly spaced relation between shroud ring and blade; Angle bar is fixedly installed between any two channel-section steels.
Optionally, the quantity of channel-section steel is 6.
Compared with prior art, the utility model is provided with channel-section steel and angle bar, decoration structure features simple design, low cost of manufacture and can guarantee that the intensity that supports is high.
Further, the quantity of channel-section steel is 6, better makes the intensity of support high.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of support of spiral classifier helical blade, this support is welded on shroud ring 2 with channel-section steel 1 one ends of model 6#, and the other end is welded on blade 4, and evenly spaced welding quantity is the channel-section steel 1 of 6 altogether between shroud ring 2 and blade 4; Be that 40 angle bar 3 is fixedly welded between any two channel-section steels 1 with model, with angle bar 3, any two channel-section steels 1 be connected and fixed connection, quantity is that the angle bar 3 of 6 surrounds a regular hexagon altogether; Both sides bolt-connection on shroud ring 2 can move on the main shaft pipe.Channel-section steel 1 first welds together with little angle bar 5, and little angle bar 5 welds together with blade 4 again.
The utility model project organization is reasonable, and intensity is high, long service life; Intermediate space is large, is beneficial to ore pulp and flows, and the stirring in production, grading effect are good; Shroud ring can move, and makes the main shaft pipe can be crooked, and helical blade is beated little, and anti-sand amount is large.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
1. the support of a spiral classifier helical blade is characterized in that: described support comprises channel-section steel (1) and angle bar (3); Described channel-section steel (1) one end is fixedly connected with shroud ring (2), and the other end is fixedly connected with blade (4), and described channel-section steel (1) is disposed in an evenly spaced relation between shroud ring (2) and blade (4); Described angle bar (3) is fixedly installed between any two channel-section steels (1).
2. support according to claim 1 is characterized in that: the quantity of described channel-section steel (1) is 6.
