Description

Reducing mechanism for the manufacture of amino film plastics

Technical field

The present invention relates to breaking method, mainly be applicable to the production of amino film plastics, belong to chemical production field.

Background technology

Amino film plastics (specifically can referring to GB13454-92) refers to take urea-formaldehyde resin or melamine resin as base material, the industrial chemicals that adds cellulose, curing agent and other additives and make is mainly used in being pressed into the structural members such as tableware, electric switch.Existing amino molding production method and equipment exist automaticity low, the shortcomings such as efficient deficiency, and production equipment wherein mostly is common chemical industry equipment, lacks the specific aim to amino film plastics itself.The present invention relates to the breaking method in the production process material pulverized, the shortcoming such as existing pulverizer exists production efficiency low, and power consumption is large.

Summary of the invention

The applicant studies for the prior art above shortcomings, and a kind of breaking method for the manufacture of amino film plastics is provided, and crush efficiency is high.

The present invention is directed to above-mentionedly in order to solve the problems of the technologies described above, the present invention adopts following technical scheme:

The present invention includes frame, on the described frame casing is installed, main shaft passes frame and is connected with two end faces of casing by bearing block, and the casing two ends arrange respectively feeder and discharger, and crushing chamber is set in the casing, the knife rest that is installed on the main shaft is set in the described crushing chamber, knife rest circumferentially is distributed with blade, it is characterized in that the inwall matched in clearance of blade and crushing chamber, and this gap width is 1mm-2mm, the blade that every circle circumferentially distributes is counted one group, and the gap width between every group of blade is 0.5-1.5mm.

Scheme is that described blade is the 2-3 group further; Feeder connects conveying worm, and described conveying worm connects feed hopper.Gap width between the inwall of blade and crushing chamber is 1.5mm, and the gap width between described every group of blade is 1mm, and described set of blades number is 2 groups.

Technique effect of the present invention is: can improve crush efficiency; The charging rate of control material makes charging rate match with the actual production capacity of pulverizer.

Description of drawings

Fig. 1 is structural representation of the present invention.

The specific embodiment

The production method of amino film plastics involved in the present invention is as follows: at first formaldehyde, urea and other auxiliary materials are obtained urea-formaldehyde resin at the reactor internal reaction, described urea-formaldehyde resin added paper pulp and other additive and enter kneader mesh, obtain slurry, described slurry inserted carry out drying in the drying machine, obtain solid-state material, the granularity plucked of this solid-state material wherein contains more lump material.The oven dry moisture of this solid-state material is controlled at below 5%, is preferably in about 3%; Evidence, when solid material moisture was controlled at 3%, the high energy of the pulverizing output of high-speed eddy pulverizers reached 800 Kg/h; And moisture is pulverized output and will be down to about 500 Kg/h when 5% left and right sides.Moisture is lower, and crushing effect and output are better, is very difficult but the moisture of aforementioned solid-state material will be controlled at below 3%, do not meet simultaneously the mobile arts demand of product yet, if but moisture is too high, do not meet equally technological requirement, bring difficulty to pulverizing simultaneously.The present invention studies by experiment, and the moisture of solid-state material is defined as below 5%, and preferred moisture scope is 3%-3.5%.

See Fig. 1, the present invention includes frame 8, casing 9 is installed on the frame, the casing 9 interior crushing chambers 11 that arrange, main shaft 4 passes crushing chamber 11, and the two ends of main shaft 4 are connected with the end face of casing 9 by bearing block 10.Knife rest 5 is installed on the main shaft 4, Disintegrating knife 14 is installed on the knife rest 5, blade 14 and crushing chamber 11 matched in clearance, main shaft 4 both sides arrange respectively left wind wheel 13 and right wind wheel 12, and casing 9 two ends arrange feeder 3 and discharger 6.The right-hand member of main shaft 4 connects belt pulley 7, and main shaft 4 connects power source by belt pulley 7 and belt (not shown in FIG.).When the present invention works, main shaft 4 high speed rotating, effect by left wind wheel 13 and right wind wheel 12 and blade 14 makes crushing chamber 11 interior generation negative pressure, material is entered by feeder 3, because the effect of centrifugal force, material is got rid of to the madial wall of crushing chamber 11, and material is subject to friction between the madial wall of Disintegrating knife 14 and crushing chamber 11, airflow function is pulverized it, simultaneously under the effect of air pressure from 6 sections self-emptyings of discharger.

Feeder of the present invention 3 upper ends arrange air inlet, be used for replenishing of air-flow, the left end of feeder 3 connects conveying worm 2, the upper end charging aperture of conveying worm 2 connects feed hopper 1, material is at feed hopper 1 interior interim storage, and by conveying worm 2 with material even, quantitative be delivered to feeder 3.

Among the present invention, crushing chamber 11 is 1mm-2mm with the gap width of Disintegrating knife 14, and counting the Disintegrating knife 14 that every circle circumferentially distributes is one group, and the gap width between every group of Disintegrating knife 14 is 0.5-1.5mm, the group number of Disintegrating knife 14 is two to three groups, and the specific embodiment of aforementioned each parameter sees Table 1.As can be seen from Table 1, gap width between the gap width of crushing chamber 11 and Disintegrating knife 14, the every group of Disintegrating knife 14 is positive correlation with pulverizing output, and with smashing fineness be negative correlativing relation, namely aforementioned two kinds of gap widths are larger, it is higher to pulverize output, and the order number is lower; Gap width is less, and it is lower then to pulverize output, and the order number is higher, and the group number of Disintegrating knife 14 is all little on output and the impact of order number, for the amino film plastics processing technology, two groups of Disintegrating knifes 14 are set get final product, and need not such as the Disintegrating knife 14 of prior art operated by rotary motion more than 3 groups.From table 1, can find out simultaneously, when the gap width of crushing chamber 11 and Disintegrating knife 14 is 1.5mm, the gap width between every group of Disintegrating knife 14 is 1mm, when the group number of Disintegrating knife 14 is 2 groups simultaneously, it is all comparatively desirable to pulverize output and order number, can reach best efficient.

Table 1

The present invention is according to the actual production capacity of high-speed eddy pulverizers, and the charging rate of solid-state material is cooperated with described actual production capacity.The method of control charging rate is by the conveying worm quantitative feed, and feeding speed is defined as 500-800 Kg/h, cooperates the pulverizing production of high-speed eddy pulverizers, improves crush efficiency.
