Embodiment Construction

[0021] Embodiments of the present invention are described below with reference to the drawings.

[0022] refer to figure 1 , an embodiment of the homogenization silo of the present invention, specifically, a polyethylene homogenization silo. It includes a bin body 1 for materials to be mixed therein and an ultrasonic level gauge LT for measuring the level of the materials. The ultrasonic level gauge LT is arranged on the top of the bin body 1 . In the present invention, with figure 1 The orientation shown shall prevail, and the direction from top to bottom is the direction from the top to the bottom of the warehouse body 1 .

[0023] Among them, the volume of the bin body 1 of the homogenizing silo is 910m 3 , the height is 23m. The bin body 1 has a first feed port 2 for the material from the extrusion granulator to enter the bin body 1, and the nozzle size of the first feed port 2 is 10". The bin body 1 has a discharge port 3 for feeding The material in the bin body 1 is...

Abstract

The invention relates to a homogenizing stock bin and a detecting method for the material level of materials in the homogenizing stock bin. The homogenizing stock bin comprises a bin body allowing the materials to be doped and mixed therein and an ultrasonic material level meter used for measuring the material level of the materials; and the ultrasonic material level meter is arranged at the top of the bin body. Compared with a weighing instrument used in the prior art, due to the fact that the cost of the ultrasonic material level meter is lower than that of the weighing instrument, the procurement cost of instrument equipment is saved; and due to the simple and convenient installation manner of the ultrasonic material level meter, the installation cost is reduced. The detecting method for the material level of the materials in the homogenizing stock bin includes the following step that the material level of the materials in the homogenizing stock bin is measured through the ultrasonic material level meter. Compared with the weighing instrument used in the prior art, the detecting method for the material level of the materials in the homogenizing stock bin is lower in cost.

Description

technical field [0001] The invention relates to a homogenizing silo and a method for detecting material levels in the homogenizing silo. Background technique [0002] The production of polyethylene uses ethylene, hydrogen, etc. as raw materials to undergo a polymerization reaction under the action of a catalyst. The polymerization reaction is carried out in a loop reactor, and the reacted slurry is dried and mixed with various additives in a certain proportion in an extrusion granulator. It is melted and mixed in the middle, and then sent to the post-processing system after underwater pelletizing and drying. The post-processing system sends the dried material products to the homogenizing silo through the air conveying system for blending, and the blended qualified particles pass through the rotary feeder and are sent to the packaging or storage bin by the conveying fan of the homogenizing silo. The homogenizing silo mixes materials of different qualities (melt index) evenly...
