Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, an embodiment of the present invention provides a powder spray premixing device, which includes: a powder feeding mechanism 10 and a pre-dissolving mechanism 20.
The powder feeding mechanism 10 is used for storing and feeding the powder to the pre-dissolving mechanism 20.
In this embodiment, the powder feeding mechanism 10 specifically includes: a powder barrel 11, a screw conveyor 12 and a deflector 13.
Wherein, powder storage bucket 11 is used for depositing dry powder, and in order to facilitate the transport of powder, this powder storage bucket 11 specifically can be a toper storage bucket, and this toper storage bucket upper portion size is great, and the lower part size is less, and the opening of this powder storage bucket 11 sets up in the bottom. Therefore, powder is convenient to gather and send during powder feeding, and the powder conveying efficiency is improved.
The bottom of the powder barrel 11 is communicated with the feed inlet of the screw conveyor 12, and the discharge port of the screw conveyor 12 is communicated with the inlet end of the inner barrel through a fluid director 13. Thus, the powder is transported laterally to the pre-dissolving mechanism 20 via the screw conveyor 12. The screw conveyor 12 is of conventional design, and the screw conveyor 12 has a conveying cylinder, a screw rod disposed in the conveying cylinder, and an external rotating motor drivingly connected to the screw rod. Therefore, when the motor works, the screw rod pushes the powder to be transversely conveyed.
The pre-dissolving mechanism 20 is used for preliminarily dissolving powder to be sprayed, and then providing preliminarily dissolved powder solution to a spraying mechanism (not shown), so that the problem that dry powder is easily blocked when the spraying mechanism recoils in the prior art can be solved.
In this embodiment, the pre-dissolving mechanism 20 includes: an inner cylinder 21, an outer cylinder 22, and a check valve 23.
The inner cylinder 21 is used for receiving the powder from the powder feeding mechanism 10. Accordingly, the inlet end of the inner cylinder 21 is communicated with the powder feeding port of the powder feeding mechanism 10, the inner cylinder 21 is accommodated in the outer cylinder 22, and the outlet end of the inner cylinder 21 extends to the outlet end of the bottom of the outer cylinder 22. Thus, the powder is fed from the inlet end and falls down along the inner cylinder 21 to the outlet end thereof. The outlet end at the bottom of the outer cylinder 22 is further connected to a check valve 23. By providing the check valve 23, the back flushing of the water flow is advantageously avoided.
The outer cylinder 22 is used for assisting the installation and fixation of the inner cylinder 21 and providing a pre-dissolving space. Specifically, the top of the outer tub 22 is provided with an inlet pipe 221. The water inlet pipe 221 extends into the outer tub 22, and the inner water inlet pipe 221 is connected to a shower head 222 provided toward the inside of the outer tub 22. Thus, a water flow for pre-dissolving the powder can be provided through the nozzle 222, and the provided water flow can dissolve the powder falling from the inner cylinder 21 below the outlet end of the inner cylinder 21, thereby forming a powder pre-dissolving solution to be provided to the spraying mechanism. At this time, a pre-dissolving space 220 is formed between the outlet end of the inner cylinder 21 and the outlet end of the bottom of the outer cylinder 22. So, be favorable to the preliminary dissolution of powder, and then can provide the powder solution of preliminary dissolution and give spraying mechanism, when having overcome spraying mechanism's recoil among the prior art, the dry powder is easily in the problem of dissolving the jam between mechanism and the spraying mechanism in advance.
In addition, in order to prevent the powder from being wetted at the outlet end of the inner cylinder 21, the powder adheres to the outlet end. A baffle 210 arranged circumferentially is further arranged outside the outlet end of the inner cylinder 21, and the outlet end of the inner cylinder 21 is accommodated in a space surrounded by the baffle 210. The baffle 210 may be attached to the outer sidewall of the inner cylinder 21. Thus, the baffle 210 encloses a protection space, thereby avoiding the problem of insufficient dissolution and adhesion caused by the contact of the powder with water flow at the outlet end.
Further, in order to achieve the full dissolution of the powder as much as possible during the pre-dissolution process, the nozzles 222 are centrally and symmetrically distributed on two sides or four sides of the inner cylinder 21, and the nozzles 222 on the two sides or four sides are inclined. In this way, the water flow sprayed from the nozzle 222 is also substantially symmetrical, which is advantageous for uniform distribution of the sprayed water flow. At this time, the water flow sprayed from the spray head 222 can form a high-speed rotating water flow in the pre-dissolving space 220 to achieve rapid and uniform dissolution of the powder. The nozzle 222 may be a fan nozzle.
In one embodiment, the outer cylinder 22 is a cone-shaped cylinder with its tip facing downward, and the water streams from the nozzles 222 are sprayed on the inner side wall of the cone-shaped outer cylinder 22. By adjusting the installation angle of the fan-shaped spray heads 222 and the size of the sprayed water flow, the water flow sprayed by each spray head 222 can cover the inner side wall of the conical outer cylinder 22, and the sprayed water flow is uniformly distributed.
In order to uniformly disperse the powder in the pre-dissolving space 220, a disperser 24 is further provided in the inner cylinder 21. The disperser 24 is a conical member with a tip facing the powder feeding port. Preferably, the inner cylinder 21, the outer cylinder 22, the disperser 24, and the powder feeding port are coaxially disposed.
Therefore, the powder entering from the inlet end of the inner cylinder 21 can be gradually dispersed on the tapered surface of the tapered member and uniformly dropped into the pre-dissolving space 220. So, through the evenly distributed of rivers and powder, be favorable to dissolving the quick even dissolution of in-process powder in advance, and then improve the utilization ratio of powder to gain better powder spraying effect.
In order to facilitate the falling of the powder after dispersion, a gap is also arranged between the lower end of the disperser 24 and the inner side wall of the inner cylinder 21. At this time, the lower end of the distributor 24 is fixed to the inner cylinder 21 by a cross-shaped connector 241 so as to form the gap.
When the powder spraying premixing device works, high-pressure water flow connected into the water inlet pipe is provided, and the water flow passes through the adjustable fan-shaped spray head to form vortex water flow in the outer cylinder; and starting the powder feeding mechanism, converging the powder conveyed by the powder feeding mechanism at the fluid director, dispersing the flowed powder in vortex water flow through the disperser, immediately and uniformly mixing, and spraying by the spraying mechanism.
In conclusion, the powder spraying premixing device provided by the utility model is provided with the pre-dissolving mechanism, the pre-dissolving mechanism can preliminarily dissolve powder to be sprayed, and further provide preliminarily dissolved powder solution for the spraying mechanism, so that the problem that dry powder is easily blocked between the pre-dissolving mechanism and the spraying mechanism when the spraying mechanism recoils in the prior art is solved.
Meanwhile, in the powder spraying premixing device, the installation mode of the spray head is reasonably designed, and the conical disperser is arranged, so that the powder can be rapidly and uniformly dissolved in a favorable way by matching the spray head with the conical disperser, the utilization rate of the powder is improved, and a better powder spraying effect is achieved.
