Description
Technical field
The present invention relates to easy powder brittle material crushing technology fields, more particularly, to a kind of broken dress of pre-screening double teeth roller
It sets.
Background technique
Needle coke is the typical example in easy powder brittle material, and this material belongs to high-quality carbon material, is manufacture superelevation
The primary raw material of power electrode is the fine quality greatly developed in carbon materials, and unit value is larger, economic value compared with
It is high.Delayed coking is to prepare a kind of technology of needle coke, and pretreated raw material carries out complex reaction in coke drum, most
Final curing is needle coke.
Needle coke needs first to carry out graded crushing operation to it, reaches certain granules degree, be convenient in storage and transportation process
Transport and storage.Needle coke particles degree is different, and the market price also differs greatly.Needle coke industry is at home also in a step
Section needs a kind of suitable crusher to replace the general crusher generallyd use at present.
Summary of the invention
The purpose of the present invention is often carry out indifference in similar materials such as broken needle cokes to solve existing crusher
Crushing, the problem of causing to being crushed again without broken material, coke breeze rate, broken power and blocking probability caused all to increase,
A kind of pre-screening double teeth roller crushing device is provided.
The deficiency of the present invention to solve above-mentioned technical problem, used technical solution is:
A kind of pre-screening double teeth roller crushing device, including crusher chamber, crusher chamber is interior to be arranged two breaker rolls, sets immediately below breaker roll
It is equipped with broken beam；Power device drives two breaker roll relative rotation and carries out brokenly in crusher chamber to material with the cooperation of broken beam
Broken operation, the entrance of the crusher chamber extend outwardly one section of casing formed for adding materials, set on the side wall of crusher chamber
It is equipped with the sizing grill that spacing is equal to broken rear material particular diameter, sizing grill bottom is connected to discharge hole of crusher, sizing grill
Top is arranged obliquely and least significant end extends to above breaker roll, and the maximum spacing between sizing grill and breaker roll is no more than broken
The partial size of product after broken, the drop guide for material diversion is equipped in casing, and drop guide end is located at sizing grill surface
Sieved in order to guide material in casing to sizing grill, subsequent sizing grill by the material of off grade size guide to
It is crushed in breaker roll.
The drop guide is located at right above breaker roll, and drop guide is extended to obliquely right above sizing grill.
The drop guide is arranged in the middle part of crusher chamber, and drop guide and casing side wall cooperatively form two loading channels.
The drop guide is arranged in the wherein side of crusher chamber, and it is logical that drop guide and casing side wall cooperatively form a charging
Road.
The sizing grill is arranged in the two sides of breaker roll or is arranged in the unilateral side of breaker roll.
The breaker roll is using any one in the breaker roll of three tooth form crushing teeths or the breaker roll of four tooth form crushing teeths
Kind.
The power device includes motor and retarder, and motor is coupled by retarder with breaker roll.
The beneficial effects of the present invention are: the present invention will meet pan feeding by increasing casing and drop guide being added in casing
The material of partial size is blocked in drop guide through the drop guide pilot flow direction sizing grill in casing, the material of simultaneously greater than pan feeding partial size
On, reduce the probability that crusher blocks；Sizing grill carries out pre-screening to the material of entrance, avoids to qualified partial size object
Unnecessary broken, the reduction coke breeze rate, the saving energy of material；Three teeth or four flute profile crushing teeths can keep pan feeding partial size and crushing force not
Roller diameter is reduced while change, reduces installed power.
Detailed description of the invention
Fig. 1 is the structure diagram under broken material of the invention.
Fig. 2 is the top view of whole equipment in the present invention.
Fig. 3 is another arragement construction schematic diagram of the invention.
Diagram label: 1, beam, 2, breaker roll, 3, sizing grill, 4, casing, 5, drop guide, 6, motor, 7, deceleration are crushed
Device.
Specific embodiment
As shown in the figure, specific embodiment is as follows:
A kind of pre-screening double teeth roller crushing device, including crusher chamber are provided with the breaker roll 2 for broken material in crusher chamber,
Breaker roll 2 uses three flute profile crushing teeth breaker rolls as shown in Figure 1, also could alternatively be the breaker roll of three flute profile crushing teeths as schemed
3；Broken beam 1 is provided with immediately below breaker roll 2, be provided with the mutually matched crushing teeth of breaker roll 2, this be this field skill
Therefore the emphasis of the common knowledge of art personnel and not the application are not described in detail；Power device drives two breaker rolls 2
Relative rotation and the cooperation of broken beam 1 carry out crushing operation to material in crusher chamber；Power device includes motor 6 and retarder 7
Two breaker rolls 2 are driven to relatively rotate.The entrance of the crusher chamber extends outwardly one section of casing formed for adding materials
4；Spacing is provided on crusher chamber side wall as shown in Figure 1 can be using two sieves equal to the sizing grill 3 of broken rear material particular diameter
Lattice grid 3, two sizing grills 3 are located at the two sides of breaker roll 2, while can be using such as a sizing grill 3 in Fig. 3
Form, sizing grill 3 are located at the wherein side of breaker roll, at the same the other side of breaker roll be less than at a distance from crusher chamber side wall it is broken
The partial size of product, 3 bottom of sizing grill are connected to discharge hole of crusher after broken, and top is arranged obliquely and least significant end extends to brokenly
Broken 2 top of roller, the maximum spacing between sizing grill 3 and breaker roll 2 prevent large-sized no more than the partial size of broken rear product
Material discharge；The drop guide 5 of material diversion effect is installed, drop guide 5 is located at right above breaker roll, and drop guide 5 in casing 4
Extended to right above sizing grill 3 obliquely, drop guide 5 can using the middle part that crusher chamber is arranged in as shown in figure 1, drop guide with
