Abstract
The utility model discloses a negative-pressure powder delivery and loading pumping head, which includes a connecting pipe connected with a vacuum loading carrier, a vacuum-pumping pipe provided with a pipe orifice connected with a vacuum generator, and a feeding pipe provided with a feed opening connected with a powder source, wherein the feeding pipe is communicated with the connecting pipe; the pipe orifice of the vacuum-pumping pipe is formed on the side wall of the connecting pipe; and the vacuum-pumping is performed when material is delivered, so that the vacuum loading carrier is vacuum all along. The negative-pressure powder delivery and loading pumping head has a simple structure, is convenient for processing and quick in adjustment, and can avoid material loss.
Description
Technical field
The utility model relates to a kind of negative pressure powder conveying device, refers in particular to the tap of a kind of negative pressure powder delivery material loading.
Background technology
In the prior art, powder delivery generally adopts the negative pressure strength to carry.The negative pressure strength is carried must include vacuum orifice and inlet point; The negative pressure pneumatic conveying mode has: one, vacuumize and charging is carried out simultaneously; This mode vacuum orifice and inlet point can divide and be arranged, and cause seal many like this, and sealing difficulty is big and problems such as loaded down with trivial details are installed; Also can vacuum orifice and inlet point be same device, i.e. vacuum orifice and inlet point unification, cyclone as shown in Figure 1; Material inlet 10 double as vacuum orifice and inlet points are during use, when negative pressure produces; Powder also runs off along with air, causes unnecessary loss, even produces dust pollution; And complex structure, it is big to change dismounting intensity; Two, vacuumize with charging and carry out step by step, can avoid material loss, but production efficiency reduces.
Seeing that the above-mentioned defective of the negative pressure powder conveying device of prior art, the inventor develops a kind of negative pressure powder delivery material loading tap that overcomes above-mentioned defective, and it is applied in the negative pressure powder conveying device, and this case produces thus.
The utility model content
The purpose of the utility model is to provide a kind of simple in structure, easy to process, adjustment rapidly and can avoid the negative pressure powder delivery material loading tap of material loss.
For reaching above-mentioned purpose, the solution of the utility model is:
The tap of a kind of negative pressure powder delivery material loading comprises and vacuum charging carrier bonded assembly connection pipe, the mouth of pipe and vacuum generator bonded assembly vacuum-pumping tube and inlet point and powder source bonded assembly feed pipe; Feed pipe connects connection pipe, and the mouth of pipe of vacuum-pumping tube is opened at the connection pipe sidewall, in convey materials, vacuumizes to make vacuum charging carrier keep the vacuum shape always.
After adopting such scheme, powder is got into by the inlet point of feed pipe, owing to vacuumize the formation negative pressure with connection pipe bonded assembly vacuum charging carrier; Powder sucks in the vacuum charging carrier; And air is discharged by the outlet of feed pipe, and therefore, the utility model has solved vacuum powder and carried air outlet and two-in-one with powder inlet; When negative pressure produces, the problem that powder also runs off along with air.

Fig. 2 is the structural representation of the utility model.
Label declaration
The utility model
Connection pipe 1 vacuum-pumping tube 2
Feed pipe 3.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done detailed explanation.
Consult shown in Figure 2ly, a kind of negative pressure powder delivery material loading tap that the utility model discloses comprises and vacuum charging carrier bonded assembly connection pipe 1, the mouth of pipe and vacuum generator bonded assembly vacuum-pumping tube 2 and inlet point and powder source bonded assembly feed pipe 3.
The mouth of pipe of connection pipe 1 and vacuum charging carrier be connected can for be threaded, flange connects, quick coupling connects.
The mouth of pipe of vacuum-pumping tube 2 is connected with the external vacuum producer, can select for use be threaded, flange connects and quick coupling connects, connecting tube can be selected different materials according to the different powder characteristic.
The mouth of pipe of feed pipe 3 is connected with powder source, can select for use be threaded, flange connects, quick coupling connects, connecting tube can be selected different materials according to the different powder characteristic.
Feed pipe 3 connects connection pipe 1, and the mouth of pipe of vacuum-pumping tube 2 is opened at connection pipe 1 sidewall, in convey materials, vacuumizes to make vacuum charging carrier keep the vacuum shape always.
When the utility model uses; The powder that the external powder source produces is got into by the inlet point of feed pipe 3; Form negative pressure owing to being evacuated by the external vacuum producer with connection pipe 1 bonded assembly vacuum charging carrier, powder sucks in the vacuum charging carrier, and air is discharged by the outlet of feed pipe 3.
Powder wastage adjustment when the length of feed pipe 3 can and vacuumize according to powder proportion; Can adjust the distance between the mouth of pipe of the mouth of pipe and feed pipe 3 of connection pipe 1, thereby the powder that runs off because of emptying gas is reduced as much as possible; And can select the caliber size of feed pipe 3 according to operational throughput.
The embodiment that the above is merely the utility model is not to this case design-calculated restriction, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
