Description
Technical field
The utility model is related to a kind of chemical industry equipment, be specifically related to it is a kind of for trimethylolpropane produce in it is reciprocal
Formula vibratory sieve.
Background technology
Industrially, TMP is mainly with hutanal and formaldehyde as primary raw material, the condensation reaction under base catalyst effect
Intermediate dihydroxymethyl butyraldehyde is obtained, the intermediate further generates trimethylolpropane with formaldehyde reaction.
The production technology of domestic trimethylolpropane is divided into sodium method and two kinds of calcium method, i.e. raw material respectively using hydrogen-oxygen at present
Change sodium or calcium hydroxide.Calcium method technique because having the advantages that short flow, low cost, labour intensity is low and environmental protection and energy saving, gradually
Substitution sodium method technique gradually.
Vibratory sieve, the generally-straight reciprocating of traditional vibratory sieve, using this can be typically used during sorting
Material moves forward on compass screen surface along straight line when the method for kind is sieved, and compass screen surface utilization rate is low；And when material (group) in heaps,
The material of only contact compass screen surface is sieved, and the material screening effect on top is poor, while there is screen cloth easily blocking up in use
The phenomenons such as plug, influence screening effect, cause screening materials carrying unqualified.
Utility model content
The technical problem that the utility model is solved be provide it is a kind of for trimethylolpropane produce in it is reciprocating
Vibratory sieve, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model is solved is realized using following technical scheme：
A kind of reciprocating vibration sieve in production for trimethylolpropane, including support, it is characterised in that the two of support
Side is respectively equipped with screen box and drive device, and the screen box is provided with feed hopper near the top of drive device side, outside feed hopper
Wall is provided with vibrator, and the bottom of screen box is pyramidal structure, and the bottom of pyramidal structure is provided with discharging opening, sieve is provided with the screen box
Screen frame frame and screen cloth, screen cloth are placed in screen frame, and one end of screen frame is connected with drive device, and the other end is through spring and sieve
Box wall is connected.
Further, the drive device includes cylinder and cylinder mounting seat, and output shaft is provided with the inside of cylinder mounting seat
Downward-sloping cylinder, the output shaft of cylinder is connected through the via of screen box side with screen frame one end, and screen frame is another
End is affixed with spring.
Further, on the same axis, the output shaft of cylinder dips down angle for the screen frame stringing and cylinder output shaft
It is oblique 15 ° -25 °.
The utility model compass screen surface utilization rate is high, and material can be avoided before blanking or in blanking process by setting vibrator
It is mixed into air and conglomeration or the generation of caking phenomenon, prevents network blocking, is moved back and forth structure using air cylinder driven screen frame
Simply, stable equipment operation.

The one end of screen frame frame 4 connects, and the other end of screen frame 4 is affixed with spring 8, and the screen frame stringing is with the output shaft of cylinder 3 same
On axis, the output shaft of cylinder 3 dips down angle for oblique 15 ° -25 °, and so far screen frame 6 can be realized inclining in screen box 9
Reciprocating motion, material can be screened into screen cloth wire side along wire side under gravity by feed hopper 5.
The utility model compass screen surface utilization rate is high, can avoid material before blanking or blanking process by setting vibrator 10
In be mixed into air and conglomeration or the generation of caking phenomenon, prevent network blocking, moved back and forth knot using air cylinder driven screen frame 6
Structure is simple, stable equipment operation.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
