Abstract

The utility model is applicable to the field of CRT (cathode ray tube) recycling, and provides a CRT cone-screen glass synchronous dissolving and soaking separation device. The separation device comprises a dissolving tank which is internally provided with a plurality of CRTs and a plurality of injection pipes that are arranged in a crisscross way, wherein the injection pipes are provided with a plurality of injection holes used for injecting solution, and the injection holes just face to sintered glass between cone glass and screen glass of the CRTs. In the utility model, the plurality of CRTs are placed in the dissolving tank, the solution is injected to the periphery of the sintered glass of the CRTs through the injection holes of the injection pipes, and the sintered glass with low melting point can be easily melted by the solution so as to separate the cone glass from the screen glass. The separation device is simple and fast in operation, high in treatment efficiency, and suitable for recycling the CRTs in batches.

Description

CRT picture tube awl panel glass dissolves the immersion tripping device synchronously

Technical field

The utility model belongs to CRT and reclaims the field, relates in particular to a kind of CRT picture tube awl panel glass and dissolves the immersion tripping device synchronously.

Background technology

The CRT picture tube mainly by being made up of the cone glass of lead and unleaded panel glass, utilizes for CRT is carried out the environmental protection resource utilization again, cone glass must be separated with panel glass when reclaiming the CRT picture tube.

Existing separation method is generally based on the physics patterning method, this method velocity of separation is fast, noiseless, but that shortcoming is an otch is not too neat, need do subsequent disposal, and dedicated separation equipment must be arranged, investment is big, the cost height, and also the physics patterning method is difficult to generally realize that cone glass and the complete of panel glass separate, can't obtain complete cone glass and panel glass, can only recycle the glass cullet that obtain.

Prior art also has by chemical dissolution method comes separation cone glass and panel glass, but owing to be used for the sintered glass of sealing-in CRT cone glass and panel glass is a kind of low melting glass of micritization, more easily be dissolved in the solution such as nitric acid, so can adopt solution such as nitric acid, organic acid, dissolve sintered glass by the mode of soaking or wash, and be aided with the separation that thermal shock is realized CRT awl panel glass.But there is following problem in this method:

(1) equipment complexity, every equipment once can only be handled an indicating meter, and the device requirement amount is big, input is high;

(2) each dissolving all needs the long time, and processing efficiency is lower;

(3) the organic acid dissolved efficiency is low, and strong inorganic acid concentration height (being generally 10%～15%) such as nitric acid, corrodibility are strong, and is high to equipment requirements;

(4) separation and cleaning are independently carried out, and need special-purpose separating device and cleaning equipment, complex procedures;

(5) the liquid waste disposal difficulty is big, processing costs is high, and secondary pollution is big.

The utility model content

Technical problem to be solved in the utility model is to provide the high CRT picture tube awl panel glass of a kind of processing efficiency to dissolve the immersion tripping device synchronously.

The utility model is to realize like this, a kind of CRT picture tube awl panel glass dissolves the immersion tripping device synchronously, comprise the dissolving tank that to place a plurality of CRT picture tubes in inside, also be provided with the spray tube of a plurality of crisscross settings in the described dissolving tank, offer a plurality of jet holes that are used to spray lysate on the described spray tube, described jet hole is over against the cone glass of described CRT picture tube and the sintered glass between the panel glass.

Particularly, a plurality of brace tables are set in the described dissolving tank, described CRT picture tube is positioned over respectively on the described brace table.

Particularly, described spray tube is connected with the inner heat pump that lysate is housed.

Compare with existing C RT picture tube awl panel glass separation method, the utility model is positioned over a plurality of CRT picture tubes in the dissolving tank, and the jet hole by spray tube sprays lysate around the sintered glass of CRT picture tube, this lysate is easy to low-melting sintered glass is melted, thereby cone glass and panel glass are separated, simple to operate, quick, the processing efficiency height is suitable for mass recycling CRT picture tube.

Description of drawings

Fig. 1 a is that the CRT picture tube awl panel glass that the utility model embodiment provides dissolves the synoptic diagram that soaks tripping device synchronously;

Fig. 1 b is that the CRT picture tube awl panel glass that the utility model embodiment provides dissolves the partial view that soaks tripping device synchronously;

Fig. 1 c is the synoptic diagram of the spray tube that provides of the utility model embodiment.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Shown in Fig. 1 a～Fig. 1 c, the CRT picture tube awl panel glass that the utility model embodiment provides dissolves the immersion tripping device synchronously, comprise dissolving tank 11, be provided with the spray tube 13 of a plurality of CRT picture tubes 12 and a plurality of crisscross settings in the dissolving tank 11, offer a plurality of jet holes 131 that are used to spray lysate on the spray tube 13, jet hole 131 is over against the cone glass 121 of CRT picture tube 12 and the sintered glass 123 between the panel glass 122.

Compare with existing C RT picture tube awl panel glass separation method, the utility model is positioned over a plurality of CRT picture tubes 12 in the dissolving tank 11, and the jet hole 131 of the spray tube 13 by crisscross setting sprays lysate around the sintered glass 123 of CRT picture tube 12, this lysate is easy to low-melting sintered glass 123 is melted, thereby cone glass 121 and panel glass 122 are separated, simple to operate, quick, the processing efficiency height is suitable for mass recycling CRT picture tube 12.

For the ease of picking and placeing of CRT picture tube 12, can in dissolving tank 11, place a plurality of brace tables 14, then CRT picture tube 12 is positioned over respectively on each brace table 14, like this, it is just very convenient to pick and place CRT picture tube 12.

Lysate in the described spray tube 13 is flowed in spray tube 13 by heat pump 15 heating and driving lysate, and lysate is ejected on the sintered glass 123 of CRT picture tube 12 after heating again, can dissolve sintered glass 123 more quickly, improves processing efficiency.

The concentration of described lysate is the salpeter solution of 4%～6% lower concentration, uses the lower concentration salpeter solution, compares the dissolved efficiency height with the organic acid solvent that prior art adopts; The salpeter solution of 10%～15% high density that adopts with prior art is compared, and has reduced the equipment anticorrosion performance demands, thereby has reduced the cost of equipment.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
