Description
Technical Field
The utility model relates to a throttling arrangement, concretely relates to throttling arrangement who uses on rotary valve upper portion.
Background
The rotary valve is also called as a rotary feeder or an air seal machine, has air locking performance and can resist certain pressure difference. The rotary valve can carry out quantitative material conveying and is a key technical device in a pneumatic conveying system. The rotary valve is composed of casing, end cover and impeller, the impeller rotates in the cylindrical casing, the material falls into the space between the blades on the impeller from the upper hopper by the gravity, the material is discharged to the discharge port at the lower part of the casing along with the rotation of the impeller and is discharged from the discharge port, or the lower part of the discharge port is connected with a pipeline, the falling material is mixed with air flow in the pipeline and reaches the destination through the pipeline under the action of pressure and air flow.
The existing rotary valves can shear at the junction of the blade top and the shell feeding port during the process of conveying large-diameter particle materials (as shown in figure 1), although there are many anti-blocking rotary valves for such particle materials, such as anti-blocking structures like W-shaped blades and V-shaped blades. However, these anti-seizing structures only change the shearing line of the feed inlet into one to two shearing points, and the anti-seizing purpose is achieved by the method of reducing shearing and shearing resistance, and the shearing cannot be completely avoided. For some materials with very high quality requirements, such as materials with no allowable crushing or very low crushing rate requirements, these anti-jamming structures are not satisfactory.
SUMMERY OF THE UTILITY MODEL
Because the reason of shearing causes the broken problem of material when solving current rotary valve and carrying large granule material, the utility model provides a throttling arrangement who uses on rotary valve upper portion.
The utility model provides a following technical scheme:
the throttling device comprises an outer barrel and an inner barrel, wherein the upper portion of the inner barrel is connected with the outer barrel, a feed inlet is formed in the upper portion of the inner barrel, an adjustable discharge port is formed in the lower portion of the inner barrel, an upper flange and a lower flange are respectively connected to the upper portion and the lower portion of the outer barrel, the upper flange is connected with a feeding device, the lower flange is connected with the rotary valve, a fixed baffle is arranged in the front of and behind the adjustable discharge port, and an adjustable baffle 9 is arranged on the left side and the right side of the adjustable baffle.
Further, the adjustable discharge port is inserted into the feed port of the rotary valve.
Furthermore, the adjustable baffle is hinged to the inner wall of the inner barrel, the outer barrel wall penetrates through a bolt, and the tail of the bolt abuts against the adjustable baffle.
Furthermore, a nut is installed at the bolt of the outer cylinder wall.
Compared with the prior art, the beneficial effects of the utility model are that: the discharge gate through adjusting throttling arrangement comes to reach required delivery capacity, then a sub-unit connection ability is greater than the rotary valve of required delivery capacity, and the material passes through throttling arrangement like this and falls the back in the below rotary valve silo, and there is not the material here, has consequently just avoided the shearing of material here, has solved current rotary valve and has caused the broken problem of material because the reason of shearing when carrying large granule material.

FIG. 2 is a schematic diagram of shearing of large particle materials.
Fig. 3 is a schematic view of the combined use of the throttling device and the rotary valve of the present invention.
In the figure: 1. an outer cylinder; 2. an inner barrel; 3. the discharge hole can be adjusted; 4. a feed inlet; 5. an upper flange; 6. a lower flange; 7. rotating the valve; 8. fixing a baffle plate; 9. an adjustable baffle; 10. a bolt; 11. and a nut.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the throttling device for use in the upper portion of the rotary valve of the present invention comprises an outer cylinder 1 and an inner cylinder 2, wherein the upper portion of the inner cylinder 2 is connected to the outer cylinder 1, the upper portion of the inner cylinder 2 is a feeding port 4, the lower portion of the inner cylinder 2 is provided with an adjustable discharging port 3, the upper portion and the lower portion of the outer cylinder 1 are respectively connected to an upper flange 5 and a lower flange 6, the upper flange 5 is connected to a feeding device, and the lower flange 6 is connected to a rotary valve 7.
Fixed baffle plates 8 are arranged in the front and the back of the adjustable discharge port 3, and adjustable baffle plates 9 are arranged on the left side and the right side for adjusting the discharge amount. The adjustable outlet 3 is inserted into the inlet of a rotary valve 7. The adjustable discharge port 3 and the size of the adjustable discharge port inserted into the rotary valve need to be adjusted according to different particle materials.
As shown in figure 3, when the material falls from the upper reaches, the required conveying capacity is reached by adjusting the discharge hole of the throttling device, then the lower part is connected with a rotary valve 7 with the capacity larger than the required conveying capacity, so that the material falls into the trough of the rotary valve 7 below through the throttling device, the material cannot fill the trough and falls into the middle bottom of the trough due to the larger capacity of the rotary valve below, when the blade of the impeller rotates to a shearing point crossed with the shell, the shearing of the material at the position is avoided due to the absence of the material at the position, and the problem of material crushing is solved.
The utility model discloses a throttling arrangement has overcome the present shearing defect that has existed in the current rotary valve, has solved current rotary valve and has caused the broken problem of material because the reason of shearing when carrying large granule material.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
