Description

Novel prevent stifled vacuum material loading machine

Technical Field

The utility model belongs to the technical field of pharmaceutical equipment technique and specifically relates to a novel prevent stifled vacuum material loading machine.

Background

The vacuum feeding machine is composed of a vacuum pump (without oil or water), a filter, a vacuum hopper, a conveying hose and other large components, and is mainly used for conveying powder and granular materials, such as bulk drug powder, chemical powder, metal oxide powder and the like. The working principle is as follows: form a vacuum air current in the hopper under the effect of vacuum pump, under the effect of this air current, the material of being delivered carries the vacuum hopper through the hose in, the filter lets the air current upwards pass through and the material then is beaten down and falls into in the vacuum hopper, play the effect that prevents the material by the suction, meanwhile, compressed air blowback device passes through pulse blowback valve self-cleaning filter, make on the filter adnexed material by in the blowback falls the vacuum hopper, prevent that the filter from being blockked up, the blowing is carried out after reaching a certain amount in the hopper.

In the in-service use discovery, the material that vacuum material loading machine inhaled in the vacuum hopper, owing to there is the air to sneak into, after the material falls into the vacuum hopper, mix together with the air, take out the air under the negative pressure suction of vacuum pump, and the material is filtered by the filter, but because reasons such as the adhesive action of material, mobility are not good, hygroscopicity, still can produce the material and bond the phenomenon on the filter, long-time piling up can block up the filter and make whole equipment can not work.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and 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.

As shown in fig. 1, as a preferred embodiment of the present invention, a novel anti-blocking vacuum feeder comprises a vacuum hopper 5, a vacuum pump connected to the vacuum hopper 5, and a filter 2 disposed in the vacuum hopper 5 and used for filtering air entering the vacuum pump, it should be noted that each component is an existing device, the specific connection is the prior art in the field, and will not be described in detail herein, the inner cavity of the vacuum hopper 5 is provided with a spiral pipe 9, the upper end of the spiral pipe 9 is connected to a feed inlet 8 of the vacuum hopper 5, the feed inlet 8 is connected to a container pipe for containing materials through a hose, the vacuum pump is connected to an air outlet 1 disposed on the true hole hopper, the lower end extends along the bottom of the vacuum hopper 5 in a spiral manner, and the vacuum hopper 5 is provided with a partition plate 3 for partitioning the inner cavity into an upper cavity 6 and a lower cavity 7, the border of baffle 3 with the inner wall connection of vacuum hopper 5, it is located to go up cavity 6 the top of cavity 7 down, just baffle 3 is provided with and is used for the intercommunication go up cavity 6 and lower cavity 7's through-hole 4, promptly the air in the cavity 7 need pass down through-hole 4 gets into go up cavity 6, then set up filter 2 in the last cavity 6 filters, at last by the vacuum pump is taken out, filter 2 sets up go up in the cavity 6 just go up cavity 6 with vacuum pump union coupling, just the lower extreme of helical pipeline 9 is located in cavity 7 down.

When the novel anti-blocking vacuum feeding mechanism provided by the utility model is applied, the spiral pipeline 9 is arranged in the vacuum hopper 5, so that the material passes through the feed inlet 8 of the vacuum hopper 5 to enter the spiral pipeline 9 under the action of negative pressure suction of the vacuum pump, then flows out of the spiral pipeline 9 to enter the inner cavity, under the spiral guide of the spiral pipeline 9, the air containing the materials is rotated, the materials are separated from the air by means of centrifugal force and collected on the pipe wall of the spiral pipeline 9, and then the materials fall into the bottom of the vacuum hopper 5 by means of the self gravity action of the materials, the materials are guided by the spiral pipeline 9 to flow out along the tangential direction of the spiral pipeline 9, so that the materials vertically and downwards acting on the materials at the bottom of the vacuum hopper 5 are prevented from splashing the materials to be mixed with air, the content of the materials in the air is reduced, and the materials are prevented from being adsorbed and bonded on the filter 2;

in addition, through setting up baffle 3 in order to incite somebody to action the inner chamber is separated, just the suction is in the vacuum hopper 5 and the air of mixing the material is located cavity 7 down, and this air need pass through-hole 4 and filter 2 in proper order and is taken out by the vacuum pump, and because through-hole 4 is less than the cross-section of cavity, consequently the air in cavity 7 passes down the through-hole 4 gets into after going up cavity 6, the velocity of flow of air can reduce suddenly to material settlement in the realization air, realize the separation, reduce the material content that gets into in the air in the cavity 6, further reduce the material by adsorption and adhesion on filter 2, avoid blockking up filter 2, prolong filter 2's life.

On the basis of the embodiment, the middle part of the partition board 3 is arranged to be downwards concave, and the through hole 4 is arranged at the lowest point of the concave part of the partition board 3, so that even if materials settled in the air in the upper cavity 6 fall on the partition board 3 and then slide and gather towards the lowest point of the concave part of the partition board 3 along the partition board 3 under the action of self weight, the materials pass through the through hole 4 again and fall into the lower cavity 7, the recovery is realized, and the waste caused by residual materials on the partition board 3 is avoided.

Preferably, the partition plate 3 is formed in an inverted cone shape, and the through hole 4 is formed at the lowest point of the inverted cone-shaped partition plate 3.

Specifically, the open area of through-hole 4 is not more than the setting and is in on the vacuum hopper 5 and be used for with the open area of vacuum pump connection's air outlet 1, guarantee when the convulsions volume of vacuum pump is fixed, the smaller the open area of through-hole 4, then the air flow rate of through-hole 4 is bigger, and with get into the velocity of flow difference in last cavity 6 bigger, and the change of velocity of flow is bigger, then the effect that the material subsides is showing more.

Specifically, the spiral pipeline 9 is fixedly connected with the inner wall of the vacuum hopper 5, and the spiral pipeline 9 is supported by the inner wall of the vacuum hopper 5.
