Abstract
The utility model discloses a powder pump which comprises a first channel, a second channel and a control device. The first channel and the second channel are parallel, the two ends of the first channel and the two ends of the second channel are provided with channel switches respectively, the control device controls on and off of the channel switches, a breathable middle pipe made of a breathable film is arranged in the middle of the first channel, a breathable middle pipe made of a breathable film is arranged in the middle of the second channel, each breathable middle pipe is wrapped by a non-breathable outer pipe, a gap is formed between each outer pipe and the corresponding breathable middle pipe, and the outer pipes are communicated with an air extractor and an inflation device. A small amount of air can drive powder to enter a powder barrel, the air-powder scale value of the gas-powder mixture entering the powder barrel is very small, and the requirement for sending powder into a sealed powder barrel is met.
Description
Technical field
The utility model relates to a kind of powder pump.
Background technology
Along with the development of spraying industry technology, existing powder room progressively starts to adopt sealed powder bucket, and powder pump is transported to spray gun inhale powder from sealed powder bucket after, and the relatively open powder bucket advantage of the process of dusting of this kind of form clearly; But the powder room that adopts this form also exists one toward interior problem (the general small volume of sealed powder bucket that adds powder difficulty of sealed powder bucket, if directly can make the gas-powder ratio value in sealed powder bucket can be very large toward filling powder in sealed powder bucket from powder case by common powder pump, in the primary mixture that indirectly causes finally spraying from spray gun, gas ratio is very high, does not reach to set to require).
For this reason, the utility model provides a kind of powder pump, can be toward the very little primary mixture of conveying gas powder ratio value in sealed powder bucket.
Utility model content
In order to address the above problem, the utility model provides a kind of powder pump toward the very little primary mixture of the interior conveying gas powder ratio value of sealed powder bucket.
The utility model solves the technical scheme that its technical problem adopts:
A kind of powder pump, comprise parallel first passage, second channel and the control device arranging, the two ends of described first passage and second channel are provided with channel switch, described control device control channel switch opens and closes, described first passage and second channel middle part are set to adopt ventilated membrane to make ventilative middle pipe, described ventilative middle pipe is wrapped with air-locked outer tube, between described outer tube and ventilative middle pipe, is provided with gap, and described outer tube is communicated with air extractor and aerating device.
Described channel switch is set to air film valve.
The beneficial effects of the utility model are: adopt the utility model specific works principle of said structure as follows, first passage is opened near the channel switch of powder case, rest channels switch cuts out, the air extractor that starts first passage is bled to first passage, in first passage, form negative pressure, from powder case, inhalation of dust is to set amount, close first passage near the channel switch of powder case, open first passage near the channel switch of powder bucket and second channel the channel switch near powder case, and start the aerating device of first passage and the air extractor of second channel, aerating device is sent into a small amount of air toward first passage and powder can be sent in powder bucket, second channel starts inhalation of dust from powder case simultaneously, then close first passage near the channel switch of powder bucket and second channel the channel switch near powder case, open first passage near the channel switch of powder case and second channel the channel switch near powder bucket, first passage is inhaled powder, second channel is toward powder feeding in powder bucket, continue circulation.The utility model can drive powder to enter powder bucket by a small amount of air, makes to enter in the primary mixture in powder bucket gas-powder ratio example value minimum, meets toward the requirement of powder feeding in sealed powder bucket.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is schematic diagram one of the present utility model (bottom is connected with powder case, and top is connected with powder bucket).
The specific embodiment
With reference to Fig. 1, the utility model is a kind of powder pump, comprise parallel first passage 1, second channel 2 and the control device arranging, the two ends of first passage 1 and second channel 2 are provided with channel switch, control device control channel switch opens and closes, and first passage 1 and second channel 2 middle parts are set to adopt the ventilative middle pipe 3 of ventilated membrane making, and ventilative middle pipe 3 is wrapped with air-locked outer tube 4, outer tube 4 and 3 of ventilative middle pipes are provided with gap, and outer tube 4 is communicated with air extractor and aerating device.Adopt the utility model specific works principle of said structure as follows: first passage 1 is near passage 71 switch opens of powder case, rest channels switch cuts out, the 51 pairs of first passages 1 of air extractor that start first passage 1 are bled, the interior formation negative pressure of first passage 1, from powder case, inhalation of dust is to set amount, close first passage 1 near the channel switch 71 of powder case, open first passage 1 near the channel switch 72 of powder bucket and second channel 2 channel switch 73 near powder case, and start the aerating device 52 of first passage 1 and the air extractor 61 of second channel 2, aerating device 52 is sent into a small amount of air toward first passage 1 and powder can be sent in powder bucket, second channel 2 starts inhalation of dust from powder case simultaneously, then close first passage 1 near the channel switch 72 of powder bucket and second channel 2 channel switch 73 near powder case, open first passage 1 near the channel switch 71 of powder case and second channel 2 channel switch near powder bucket 74, first passage 1 is inhaled powder, second channel 2 is toward powder feeding in powder bucket, continue circulation.The utility model can drive powder to enter powder bucket by a small amount of air, makes to enter in the primary mixture in powder bucket gas-powder ratio example value minimum, meets toward the requirement of powder feeding in sealed powder bucket.
Wherein, channel switch is preferably air film valve, controls the switching of air film valve by controlling air-flow.Air film valve tool is with low cost, simple in structure, steady operation and other merits.
Above-described embodiment is preferred version of the present utility model, and the utility model also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replace is all included in the scope that the application's claim sets.
