The utility model discloses in, low melting point material is at the rotary valve unloading in-process, though received the influence of high temperature, nevertheless sweeps because of the dry compressed air that the outside comes, leads to heat and temperature all to be blown away, can't form at case position material caking.
Description
Technical Field
The utility model relates to a rotary valve technical field.
Background
The most basic function of the rotary valve is to quantify the blanking amount according to the size and the depth of the inner core of the rotary valve, and the rotary valve is used as the most basic blanking device according to the production size and the production capacity of each crystallization bed and the time and the operation amount required for drying slices. The crystallization bed can generate high temperature in the process of heating moisture of the dehumidifying slice, so the crystallization bed is very important for the blanking control of a rotary valve, and common production enterprises adopt stepless speed change and control the blanking amount through frequency conversion. Because the rotary valve is arranged at the upper part of the crystallization bed, the temperature of the conduction of the crystallization bed is higher, and the materials with lower melting points can form lumps, so that the lumps directly block the rotary valve core, and the external transmission motor and the chain work hard, so that equipment is damaged and cannot run after each blocking.
For enterprises producing various slices such as PPT, PBT and the like, the rotary valve is frequently clamped due to different shapes and melting points of the slices, so that the rotary valve is damaged in a large area, the support of the rotary valve body is deformed, the base of the rotary valve motor is damaged, the rotary valve chain is cracked and damaged, and the like, and the production and the use are seriously influenced. Frequent jamming of the rotary valve can lead to unstable production and serious risks of material breakage, and causes production stoppage, increase of equipment operation cost and increase of maintenance cost for enterprises, so that the rotary valve is very necessary for modification.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned prior art not enough, provide a rotary valve, low melting point material is at rotary valve unloading in-process, though received the influence of high temperature, nevertheless sweeps because of the dry compressed air that the outside comes, leads to heat and temperature all to be blown away, can't form at the case position material caking.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a rotary valve comprises a rotary valve body, wherein an upper flange and a lower flange are respectively arranged at the upper end and the lower end of the rotary valve body, a triangular cone portion protruding outwards is arranged at the upper end of the annular wall of the rotary valve body, a through hole communicated with the inside of the rotary valve body is formed in one side wall of the triangular cone portion, a quick-change connector is mounted on the through hole, and the quick-change connector is connected with a gas pipe.
The annular outer wall of the rotary valve body is provided with a reinforcing rib.
The number of strengthening rib is two and strengthening rib concentric distribution, the triangle pyramis is located between two strengthening ribs.
The utility model has the advantages that: low melting point material is at the rotary valve unloading in-process, although received the influence of high temperature, nevertheless sweeps because of the dry compressed air that the outside comes, leads to heat and temperature all to be blown away, can't form at case position material caking, has effectively solved the problem of low melting point material caking card valve.
Drawings
FIG. 1 is a front view of a rotary valve of the present invention;
fig. 2 is a schematic view of the installation of the air tube of the present invention.
In the figure: the rotary valve comprises a rotary valve body 1, an upper flange 2, a lower flange 3, a reinforcing rib 4, a triangular cone part 5, a through hole 6, a quick-change connector 7 and an air pipe 8.
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1 and 2, a rotary valve includes a rotary valve body 1, an upper flange 2 and a lower flange 3 are respectively disposed at upper and lower ends of the rotary valve body 1, and the upper flange 2 and the lower flange 3 are used for connecting and mounting the rotary valve (in the present invention, common parts of the rotary valve such as a motor are omitted, and therefore, these common parts are prior art and are not described herein).
The upper end of the annular wall of the rotary valve body 1 is provided with the triangular cone part 5 protruding outwards, the triangular cone part 5 is close to the feeding port at the upper end of the rotary valve body 1, the space of the triangular cone part 5 is large, dead materials are easily formed after the materials are accumulated, agglomeration is formed after the materials are accumulated for a long time under the influence of high temperature, and the valve core part is easily blocked in the feeding process of the agglomeration.
A through hole 6 communicated with the inside of the rotary valve body 1 is formed in one side wall of the triangular cone part 5, a quick-change connector 7 is installed on the through hole 6, and the quick-change connector 7 is connected with an air pipe 8.
The annular outer wall of the rotary valve body 1 is provided with a reinforcing rib 4.
The number of the reinforcing ribs 4 is two, the reinforcing ribs 4 are concentrically distributed, and the triangular conical part 5 is positioned between the two reinforcing ribs 4. The bead 4 can improve the structural strength of the rotary valve body 1 and also the structural strength of the triangular cone portion 5.
The utility model discloses a transformation process does: 1. selecting a punching position: punching a side wall of the triangular cone part 5 and punching a through hole 6, wherein an M12 twist drill is selected for punching;
2. the quick-change joint 7 with the caliber 8 is installed at the through hole 6 after punching, the gas pipe 8 with the caliber 8 is connected at the quick-change joint 7, and the third adjusting ball valve is additionally installed;
3. the compressed air needs to control the flow and pressure, and 0.2-0.3MPa of compressed air is adopted, and the flow is 0.02M3/min。
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
