Abstract
The utility model discloses a powder return structure of a catcher in unloading; belongs to the technical field of powder return of a discharger; the technical key point of the device comprises a catcher and a discharger connected to a discharge hole of the catcher, wherein a powder return pipe connected to the catcher is arranged on the discharger, and an included angle alpha between the powder return pipe and the horizontal plane is 70-80 degrees; the powder return pipe is provided with a vibration anti-blocking assembly, and the powder return pipe is provided with a regulating valve; the utility model aims to provide a catcher discharging powder return structure which is simple in structure and not easy to block; is used for returning the redundant powder in the catcher discharger.
Description
Technical Field
The utility model relates to a powder return structure, in particular to a powder return structure for discharging a catcher.
Background
The crushed powder products are sucked into a catcher by a fan in a grading way, and the powder collected by the catcher is conveyed to a discharger by a screw and then conveyed into a finished product tank by air. Because the powder is transported from the catcher spiral can be more and less, when the powder amount of the blanking is large, the wind sending load of the fan is easily caused to be overlarge when the powder amount is overlarge, and related problems such as pipe blockage are easily caused. Therefore, a residual powder return pipe is usually arranged on the spiral conveying, and the residual powder is pumped back into the finished dust remover through negative pressure wind of the dust remover.
Because the dust remover sets up on the top of packaging can, the slope is big, and helical piping is far away with the finished product material jar distance again, leads to promptly needing to settle very long surplus powder back flow, if the dust remover return air volume is less, can cause the powder to appear subsideing on the return air pipeline, causes the stifled pipe easily, causes the extrusion of the powder of tripper the inside, leads to the sealed rubber ring of tripper to prop broken, loses sealed effect, and the powder can be sprayed out from sealed rubber ring because of the pressure is too big in the tripper.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art, and provides a powder discharging and returning structure of a catcher, which is simple in structure and not easy to block.
The technical scheme of the utility model is realized as follows: the powder returning structure comprises a catcher and a discharger connected to a discharge hole of the catcher, wherein a powder returning pipe connected to the catcher is obliquely arranged on the discharger; the powder return pipe is provided with a vibration anti-blocking component, and the powder return pipe is provided with a regulating valve.
In the powder returning structure of unloading of the catcher, the vibration anti-blocking component comprises a soft connecting pipe arranged at two ends of the powder returning pipe, and mounting pipes connected with the soft connecting pipe through flanges are respectively arranged on the catcher and the discharger.
In the unloading powder return structure of the catcher, the included angle alpha between the powder return pipe and the horizontal plane is 70-80 DEG
After the structure is adopted, the powder return pipe is arranged between the discharger and the catcher, the distance between the discharger and the catcher is very short, the air quantity of the catcher is sufficient, the powder return effect can be effectively ensured, the damage of the sealing rubber ring of the discharger to produce powder spraying is reduced, the clean production environment is ensured, and the service life of equipment is prolonged. Meanwhile, the length of the powder return pipe is shortened, the gradient of the powder return pipe is set to be 70-80 degrees, and the possibility that powder is blocked in the powder return pipe is reduced.
Meanwhile, the vibration powder return pipe of the vibration anti-blocking assembly is arranged, so that the possibility that powder is accumulated and blocked in the powder return pipe is further reduced.
Drawings
The utility model is described in further detail below in connection with the embodiments in the drawings, but is not to be construed as limiting the utility model in any way.
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a schematic diagram of the front view structure of the present utility model.
In the figure: 1. a catcher; 2. a discharger; 3. a powder return pipe; 4. a vibration anti-blocking assembly; 4a, a soft connecting tube; 4b, installing a pipe; 5. and (3) regulating the valve.
Description of the embodiments
Referring to fig. 1-2, the unloading powder return structure of the catcher comprises a catcher 1 and a discharger 2 connected with a discharge hole of the catcher 1, wherein a powder return pipe 3 connected to the catcher 1 is arranged on the discharger 2, and an included angle alpha between the powder return pipe 3 and a horizontal plane is 70-80 degrees; the powder return pipe 3 is provided with a vibration anti-blocking component 4, and the powder return pipe 3 is provided with a regulating valve 5. The powder return pipe is arranged between the discharger and the catcher, and the negative pressure air of the catcher is utilized to recycle redundant powder in the discharger, so that the length of the powder return pipe is reduced, and the sufficient air quantity of the powder return can be effectively ensured. The size of the reflux air quantity is controlled through the regulating valve, so that the air quantity in the feed back pipe can be ensured to withdraw redundant powder without influencing discharging.
In this embodiment, the vibration anti-blocking assembly 4 includes a flexible connecting pipe 4a disposed at two ends of the powder return pipe 3, and mounting pipes 4b flange-connected with the flexible connecting pipe 4a are respectively disposed on the catcher 1 and the discharger 2. When the equipment is in operation, the spiral conveyor and the discharger in the catcher vibrate, and the powder return pipe is in flexible connection with the soft connecting pipe to shake, so that powder in the powder return pipe is kept in a loose state, and accumulation and blockage are avoided. And when the powder return pipe is blocked, the powder return pipe can be detached to clean out the powder therein.
During operation, crushed and ground powder products are sucked into the catcher by the blower for collecting in grades, the collected powder is conveyed to the discharger through the catcher to be conveyed into the finished product tank by the output air of the discharger, and redundant powder in the discharger is pumped back to the catcher through the powder return pipe for collecting again.
The above examples are provided for convenience of description of the present utility model and are not to be construed as limiting the utility model in any way, and any person skilled in the art will make partial changes or modifications to the utility model by using the disclosed technical content without departing from the technical features of the utility model.
