Abstract

The utility model relates to a drier which is composed of a main body, a pedestal and a vibrating motor, wherein, the main body comprises an inner cylinder, an outer cylinder and a spiral sieve plate; a feeding hole is arranged at the side lower part of the main body, and a discharge hole is arranged at the side upper part of the main body. A drying medium adopts the gradation entering method and the gradation expelling method. The utility model has the characteristics of long service life, low cost, favorable drying effect, homogeneous material movement, small impact load of sieve plate, etc. In the material drying process, the material can upward move along the sieve plate; so the utility model can be used for the joint operation of the drying and the vertical transport of the material in the fields of chemical industry, food, medicine, etc.

Description

Drier with spiral and vertical transport and vibration

The utility model belongs to a kind of spiral vibrating dryer, is specially adapted to the drying and the vertical conveying integration of operation of material.

In recent years, various vibrating dryers are come out one after another.If from the layout of sieve plate, have the horizontal circle formula, screw type, Zigzag type is also arranged.But,, all adopt top charging, bottom discharge method from the charging and the discharge method of material.Once the application number that designed as the inventor is the telescopic spiral vibrating drying machine of " CN88216626 ", the sieve plate of this drier host machine body is arranged between inner core and the urceolus with spiral form, hot blast stratified charge by the inner core introduction, and discharge the waste gas that contains moisture content by the annular space layering that forms between urceolus and the shell, and material is from the top charging and in the exciting force lower edge of vibrating motor sieve plate operation bottom discharging.Though the drying machine that this patent application provided has advantages such as drying effect is good, the sieve plate shock loading is little, and material movement is even, because the restriction to some extent in practical application of the charging of its material and discharge method.Such as: for the drying of the bigger material of water content, often adopt two drying machines further dry, promptly through the material of first drying machine drying send into second drying machine continue dry, yet will be when material is sent into second drying machine by means of lifting device.And for example: when producing chemical fertilizer in chemical fertilizer factory, after tube kiln drier drying, need be after cooler cools off immediately can the finished product pack, thereby in the intermediate link of drying machine and cooler, also need the lifting device that adds.This shows that existing drying machine certainly will increase optional equipment when drying and vertical conveying integration of operation, thereby causes unfavorable factors such as investment increases, labour intensity is big.

In view of the weak point of existing drying machine, the utility model provides that a kind of to have a drying effect good, and vibrating dryer that again can vertical conveying in drying.

For achieving the above object, the spiral vertical vibrating drying machine that the utility model provides is realized by following mode.According to structural representation shown in the drawings, the utility model comprises main body, base (10) and vibrating motor (11) composition, and spring (9) is set between main body and the base, and vibrating motor is arranged on the main body below.Main body comprises exhaust outlet (1), aiutage (2), sieve plate (3), column (4), urceolus (5), central tube (6), charging aperture (7), discharging opening (13) composition, sieve plate is arranged between central tube and the urceolus with spiral form, the plurality of rows column evenly is set between the sieve plate layer, on the central tube of introduction hot blast the air admission hole J that enters the sieve plate interlayer is set ₁, J ₂, J ₃, the steam vent P by the moisture gas of sieve plate layer is set on the urceolus ₁, P ₂, P ₃On the outer wall of urceolus aiutage is set, the gas of steam vent is discharged by the exhaust outlet that is arranged on the urceolus through aiutage, charging aperture is arranged on the side-lower of main body, discharging opening is arranged at the side top of main body, and discharging opening and charging aperture are connected so that the turnover of material with the two ends of sieve plate respectively.The number of air admission hole J, steam vent P and hole area depend on the sieve plate number of plies, but air admission hole and steam vent are arranged to stagger mutually and be beneficial to making full use of of drying medium.As J ₃The hot blast of coming in is as far as possible evenly by the sieve plate layer and by P ₃Discharge same J ₂Air quantity by P ₂Discharge J ₁Air quantity by P ₁Discharge.

Having chassis (8) below of certain intensity in the main body fixing is two iron plates (12) of symmetry with the main body center line, identical vibrating motor (11) all is set on the every iron plate, and the setting angle of two vibrating motors staggers mutually, the exciting force that two vibrating motors are produced on horizontal plane is consistent with the hand of spiral of main body sieve plate, thereby material is upwards moved at the effect lower edge of exciting force sieve plate in dry run.Several springs (9) evenly are set between chassis and the base (10), and base can be made into circle.

The utility model is according to the vertical conveying vibrating dryer of the above-mentioned spiral that structure provided.Except having characteristics such as drying effect is good, the sieve plate shock loading is little, material movement is even, material is moved upward, and, making the weight saving of main body because the aiutage form is adopted in the discharge of the waste gas of water content, material therefor is saved.The utility model can be widely used in the integration of operation of the dry and vertical conveying of material in chemical industry, food, the medicine and other fields.

Claims

1, the vertical conveying vibrating dryer of a kind of spiral comprises main body, vibrating motor, base, between main body and the base spring is set, two vibrating motors are separately fixed on two iron plates of below, main body chassis, central tube and urceolus are arranged on the chassis in the main body, sieve plate is arranged between central tube and the urceolus with spiral form, between the sieve plate layer column is set, the main body top is provided with exhaust outlet, air admission hole is set on the central tube, steam vent is set on the urceolus, stagger mutually in the position that it is characterized in that each air admission hole and steam vent, be positioned on the outer wall of urceolus on the position of steam vent aiutage is set, each aiutage is incorporated into exhaust outlet, the side-lower of urceolus is provided with charging aperture, the side top of urceolus is provided with discharging opening, and the exciting force direction that the setting angle of vibrating motor will make vibrating motor produce on horizontal circle is consistent with the hand of spiral of sieve plate.

2, according to the vertical conveying vibrating dryer of the described spiral of claim 1, it is circular to it is characterized in that base adopts.
