Abstract
The utility model relates to a power slurry double-filling supply device which comprises a power slurry carrier groove body and a spiral pressure feeding pump which is communicated with the lower end of the power slurry carrier groove body and communicated with the power slurry carrier groove body, wherein the spiral pressure feeding pump is communicated with a powder receiving funnel which is arranged on the upper part of the power slurry carrier groove body through a T-tube and a three-way magnetic valve, and another channel of the T-tube is communicated with the powder receiving funnel which is arranged on the upper part of the power slurry carrier groove body through a flow adjusting valve and the three-way magnetic valve. In the utility model, a secondary flow adjusting valve is additionally arranged between the flow adjusting valve which is arranged in an original by-pass circuit and the powder receiving funnel, and meanwhile, a flow opening is additionally arranged on an upper pipe opening of a reflux funnel of a flour slurry carrier, so that the continuous and stable supply of a second supply circuit is realized. The defects that two varieties are originally filled in the same channel supply system, and the difference adjustment and the large difference position injection of flow can not be realized are effectively soleved. The technology design space that double varieties are produced in the same spreading screen production line is widened.
Description
Technical field
The powder slurry that the utility model relates to a kind of fluorescent screen when carrying out the spin coated of three toners slurries injects feed mechanism, the two injection feedwaies of powder slurry when particularly a kind of color picture tube and colour display tube fluorescent screen carry out the spin coated of three toners slurry.
Background technology
In the production process of color picture tube and colour display tube, the manufacturing of face is crux link the most in the fluorescent screen production process.In the spin coated process of three-color phosphor, flow into the screen inner face on phosphor slurry be constant proportion, the uniform powder slurry suspension of viscosity, it is mainly by detecting the proportion viscosity of powder slurry in the adjusting device revisal control powder stock tank, spiral force lift powder feeding slurry by cell body bottom enters and is back to cell body behind the three-way magnetic valve that the powder slurry injects or injects in the screen by injecting nozzle again, powder slurry in the realization whole process of production is stable uninterruptedly to circulate, bypass flow by spiral force lift exit is regulated, can realize combining the control injection rate with injection length to injecting the adjusting of path powder slurry flow.When same production line carried out the compatible production of two kinds, the different cultivars screen needed different injection rates, and it is separate, adjustable flexibly to guarantee that screen applies, the expansion technological requirement needs two kinds to inject state.Original two kinds are injected by using different injection signal controlling to realize that different injection lengths reach the purpose of using different injection rates, owing to use same infusion circuit, the flow of powder slurry can't be distinguished adjustment, simultaneously when production engineering specifications is implemented in the position that differs greatly and injects (for example different station injection) respectively, present injected system can't satisfy, limited the technological design space, especially carrying out fast beat is coated with screen and adds man-hour, the injection length adjustable extent is dwindled, two kind injection rate differences are difficult to satisfy, influence the bad and grade of powder slurry coating, restriction is coated with the raising of screen yields.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of use simple, stable, can realize injecting the two injection feedwaies of powder slurry of flow, position difference adjustment.
For achieving the above object, the technical solution adopted in the utility model is: comprise powder slurry dolly cell body and be arranged on the spiral force lift that powder slurry dolly cell body lower end is connected with powder slurry dolly cell body, the spiral force lift is connected by threeway, three-way magnetic valve and the powder funnel that connects that is arranged on powder slurry dolly cell body upper end, be characterized in that another road of threeway is connected with the powder funnel that connects that is arranged on powder slurry dolly cell body upper end by flow control valve and three-way magnetic valve.
Another characteristics of the present utility model are: also can be provided with another threeway on the pipeline between flow control valve and the three-way magnetic valve, the inlet of this threeway is connected with flow control valve, one outlet is connected with three-way magnetic valve, another outlet by flow control valve direct with connect the powder funnel and be connected.
The utility model is at the flow control valve of original bypass circulation and connect and install the two_stage flow control valve between the powder funnel additional, and draws the second road powder slurry supply passageway by inserting threeway between two flow control valves, enters the second the tunnel and injects magnetic valve.At the backflow funnel upper orifice increase head piece of powder slurry dolly, realized the uninterrupted stable supplying of second supply circuit simultaneously.Effectively solved and originally in the feed system of same road, carried out two kinds and inject and to realize the difference adjustment of flow and deficiency that the position that differs greatly is injected, effectively widened same the technological design space when being coated with the screen production line and carrying out that two kinds are compatible produces.
Description of drawings
Accompanying drawing is an overall structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to accompanying drawing, the utility model comprises powder slurry dolly cell body 10 and is arranged on the spiral force lift 1 that powder slurry dolly cell body 10 lower ends are connected with powder slurry dolly cell body 10, spiral force lift 1 is connected by threeway 2, three-way magnetic valve 9 and the powder funnel 8 that connects that is arranged on powder slurry dolly cell body 10 upper ends, another road of threeway 2 is connected with the powder funnel 7 that connects that is arranged on powder slurry dolly cell body 10 upper ends by flow control valve 3, threeway 4 and three-way magnetic valve 6, another outlet of threeway 4 by flow control valve 5 directly with connect powder funnel 7 and be connected.
Spiral force lift 1 connects threeway 2 with the shunting of powder slurry, one the tunnel enter that first supply circuit arrives that three-way magnetic valve 9 that the powder slurry injects is back to powder slurry dolly cell body 10 upper ends again connect powder funnel 8, another road arrives threeway 4 by flow control valve 3 and is divided into two-way, wherein a road enter that second supply circuit arrives that three-way magnetic valve 6 that the powder slurry injects is back to that powder starches four recessing bodies, 10 upper ends again connect powder funnel 7, remaining powder slurry then connects powder funnel 7 by what flow control valve 5 was back to powder slurry dolly cell body 10 upper ends.Design by above-mentioned pair of injection feedway connects use, has realized that same set of powder slurry control device drives the requirement of two cover injected systems, and two cover injection feedwaies are independent adjustable, use flexibly.And all realized flow change elements such as no flow control valve at the infusion circuit of this pair injection feedway, finally realized the obstacle steady flow of injected system.The utility model is controlled the final capacity of returns of powder slurry backflow funnel by the adjustment of bipolar flow adjustable valve, thereby the total flow of the two injected systems of control, the discharge relation that distributes the two again by the one-level Flow-rate adjustment, the final difference adjustment that realizes two injected system flows.
