Description

A kind of equipment of resin making

(1) technical field:

The utility model relates to the urea-formaldehyde resin in a kind of wood-processing industry that is applied in, particularly wood-based plate industry, is specifically related to a kind of equipment of resin making.

(2) background technology:

Urea-formaldehyde resin (glue) is to be basic raw material with formaldehyde and urea, and a kind of thermosetting resin by chemical addition, polycondensation obtain is usually used in wood working industry.Existing urea-formaldehyde resin production technique and equipment adopt three layers of civil engineering building or the design of Steel Bracket load larrying member, and formaldehyde storage tank, formaldehyde pump, urea bucket and glue storage tank are positioned at bottom, reactor is positioned at the middle level flooring; Formaldehyde test tank, loading hopper are positioned at upper floor, electric block is suspended to the upper strata back timber.At first, the formaldehyde pump startup is transported to the formaldehyde test tank on upper strata with the formaldehyde in the formaldehyde storage tank, flows automatically in the reactor after the electronic measuring scale metering of formaldehyde test tank bottom; The operator starts electric block then going up the urea bucket as the packed urea, and the urea bucket is risen to upper floor together with urea, deposits upper floor after manually unloading, and then packed urea is poured into loading hopper drops in the reactor and react; At last urea-formaldehyde resin gravity flow (or pump delivery) to the glue storage tank of bottom that generates in the reactor is deposited.The urea-formaldehyde resin production unit of this structure has the following disadvantages:

1, need build the trouble-free operation that three layers of civil engineering building (or Steel Bracket) can guarantee equipment, and to each floor particularly the weight capacity of upper strata floor and upper strata back timber have relatively high expectations, therefore, no matter be civil engineering or its investment of steel structure is all very big, cost is high;

2, because the installation of formaldehyde test tank and electric block need be carried out high weighted design to floor, in case the weight capacity of flooring is low excessively, the just danger that can occur caving in, safety coefficient is lower;

3, because formaldehyde and urea are to be promoted to the upper strata to feed intake, the distance that promotes formaldehyde and urea is higher, needs to adopt powerful formaldehyde pump and electric block like this, the equipment investment cost height, and equipment running cost is also high;

4, because formaldehyde and urea are to be promoted to the upper strata to feed intake,, so not only need to expend more labor force, and prolonged the time that formaldehyde and urea feed intake greatly, reduced working efficiency so need a lot of middle-chains;

5, feeding intake of each urea poured in the still by the urea loading hopper, thus urea feed intake inhomogeneously, influenced the reaction effect in the reactor, finally cause the downgrade of urea-formaldehyde resin.

(3) utility model content:

Technical problem to be solved in the utility model provides a kind of less investment, a kind of equipment of resin making that efficient is high.

For addressing the above problem, a kind of equipment of resin making that the utility model is designed comprises reactor, formaldehyde storage tank, urea bucket and glue storage tank, and reactor is provided with formaldehyde inlet and urea charging opening.The urea bucket is communicated with reactor by a spiral feeder, and this spiral feeder comprises opening for feed, spirochete, discharge port and transmission rig, and the opening for feed of spiral feeder links to each other with the urea bucket, and its discharge port links to each other with the urea opening for feed of reactor.This moment, the urea bucket was positioned at the bottom of support, when we when bottom is directly put into the urea that measures in the urea bucket, urea slowly is delivered to the urea charging opening under the drive of spiral feeder, and then enters reactor and react.So just reduced the material loading time of urea, saved artificial; And charging is more even, also is more conducive to the glue reaction; Also improved simultaneously the safety coefficient of producing greatly.

In the such scheme, can be promoted in the loading hopper in order to ensure the urea in the urea bucket, spiral feeder is a long spirochaeta recta that is connected across between urea bucket and the urea charging opening, and the angle of its spirochete and horizontal plane is between 45 °～90 °, is preferably 55 °.

Reactor places on the electronic scales that can measure the reactor changes in weight, and its formaldehyde inlet directly is communicated with the formaldehyde storage tank by the formaldehyde pipeline.Directly in the bottom of reactor electronic scales being set comes the PARA FORMALDEHYDE PRILLS(91,95) input amount to measure, not only save the input of formaldehyde scale tank, also reduced unnecessary material loading link, improved working efficiency, and make the support number of plies of erecting equipment become two-layer by three layers, need not high weighted design simultaneously can realize, thereby has saved construction investment greatly.

In the such scheme, weigh, on the formaldehyde pipeline between formaldehyde storage tank and reactor, also be in series with a formaldehyde pump for making formaldehyde be transported to reactor voluntarily.

The utility model compared with prior art has following having a few:

1, saves the input of equipment such as formaldehyde scale tank and electric hoist, can save installing material about 30% simultaneously;

2, the support number of plies reduces, and has not only reduced unnecessary material loading link, and the input of having saved manpower also made the material loading time decreased nearly about 30 minutes, effectively raised working efficiency;

3, urea is directly sent into after bottom is weighed in the reactor, makes that like this charging is more even, more helps the glue reaction, thereby has guaranteed the quality of urea-formaldehyde resin;

4, the three-decker of former civil engineering support or Steel Bracket changes two-layer structure into, need not to carry out the high weighted design of support simultaneously, not only save construction investment about 45%, also make the safety coefficient of producing improve greatly.
