Description
Technical field
The utility model relates to a kind of efficient heating devices, for heating siccative under mixing state.
Background technique
Currently, when to siccative carrying out that heating is mixed, to guarantee to reach the higher temperature for meeting technique requirement, obtaining reason
The heating effect thought needs to maintain certain heating time.It having a disadvantage in that, heating efficiency is low, influence production efficiency, and by
It is the mode heated when being mixed in what is taken, prolonged be mixed will will lead to the broken of solid granular material
It is broken, so that influencing the grain size proportion of product influences product quality.
Utility model content
The utility model proposes a kind of efficient heating device, its object is to: shorten the time that heating is mixed, mentions
High heating efficiency；Meanwhile avoiding that the broken of solid granular material caused by material is mixed for a long time, guarantee product matter
Amount.
Technical solutions of the utility model are as follows:
A kind of efficient heating device, including cylinder body are equipped with revolution stirring knife in cylinder body, before the axis of the stirring knife is in parallel
It moves towards afterwards and height is consistent, the cross section profile on inboard wall of cylinder block front-rear direction includes corresponding and being coaxially disposed in institute with stirring knife
Lower arc section below corresponding stirring knife, the efficient heating device further includes the first heating group heated to cylinder base
Part, twice of the ratio L/2R of the length L of the cylinder body in the longitudinal direction and lower arc section radius R are greater than 2.0 and are less than
6.3。
As further improvement of the utility model: L/2R is more than or equal to 2.1 and is less than or equal to 4.6.
As further improvement of the utility model: cylinder body is equipped with top cover, and top cover and stirring knife axis of rotation are in vertical direction
On distance H and lower arc section radius R twice of ratio H/2R less than 0.7.
As further improvement of the utility model: the top cover is equipped with the second heating component, in heating cylinder body
Material.
As further improvement of the utility model: the stirring knife quantity is one to four.
Compared with the existing technology, the utility model has the positive effect that: (1) the utility model is joined by cylinder body key
Several designs increases the material ratio in efficient heat transfer region, increases heat transfer area, shortens heating time, improves and adds
The thermal efficiency, while the Crushing Problem of solid granular material caused by being mixed because of long-time is effectively prevented, improve production
Quality；(2) the utility model can also effectively have dropped height of the cylinder body top cover away from stirring knife axis of rotation, and at top cover
It arranges the second heating component, enhances heating of the top cover to material；It heats simultaneously up and down, further improves heating efficiency.
Detailed description of the invention
Fig. 1 is the cross sectional shape schematic diagram of the utility model cylinder body.
Fig. 2 is the schematic side view of cylinder body.
Fig. 3 is the relation curve met between the heating time of product requirement and cylinder body draw ratio L/2R.
Specific embodiment
The technical solution that according to the present invention will be described in detail below with reference to the accompanying drawings:
A kind of efficient heating device, including cylinder body are equipped with revolution stirring knife in cylinder body in parallel, and usually one to four.Institute
The axis for stating stirring knife is front and back trend and height is consistent.
Such as Fig. 1, the cross section profile on inboard wall of cylinder block front-rear direction include correspond and be coaxially disposed with stirring knife in pair
Answer the lower arc section below stirring knife；Efficient heating device further includes the first heating component heated to cylinder base.
When work, the siccative in cylinder body is heated when being mixed by stirring knife.
As Fig. 1 and 2, the length L of the cylinder body in the longitudinal direction and twice of the ratio L/2R of lower arc section radius R are big
In 2.0 and less than 6.3.Preferably, L/2R is more than or equal to 2.1 and is less than or equal to 4.6.
Fig. 3 is the relation curve between the heating time obtained by comparative experiments and cylinder body draw ratio L/2R.It tested
Journey are as follows: production multiple groups cylinder body, the cross sectional shape of all cylinder bodies is identical, and only length L is different；Under same external heating condition,
The siccative for launching equivalent respectively into cylinder body is heated when being mixed, until siccative temperature reaches identical technological temperature and wants
It asks；The heating time of each cylinder body, such as following table are recorded, and draws relation curve according to the data.
Table 1 --- the experimental result about relationship between heating time and draw ratio (L/2R)
L/2R is bigger it can be seen from the relation curve, and heating time is shorter.Especially when L/2R is greater than 2.2, heating effect
Fruit is obviously improved.Will increase the volume and weight of equipment in view of cylinder body is too long, L/2R range of choice be recommended as being greater than 2.0 and
Less than 6.3.Further, when L/2R is more than or equal to 2.1 and is less than or equal to 4.6, the volume weight of heating time and equipment it
Between can obtain preferable balance.
Cylinder body is equipped with top cover, top cover and stirring knife axis of rotation in the vertical direction distance H and lower arc section radius R two
Times ratio H/2R less than 0.7, top cover and stirring knife axis of rotation distance H in the vertical direction are reduced, thus at the top of reducing
The thermal loss of siccative.
In order to further promote heating effect, the second heating component is added on top cover, enhances top cover to material
Heating simultaneously heats siccative from upper and lower both direction.
The heating component can be electric heater unit, be also possible to be laid on the heating such as heat carrier pipeline on cylinder body
Device.
