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.
Utility model content
The purpose of this utility model is to solve existing crusher and often carrying out nothing in similar materials such as broken needle cokes
The crushing of difference, is caused to being crushed again without broken material, leads to coke breeze rate, broken power and blocking probability is all increased to ask
Topic, provides a kind of pre-screening double teeth roller crushing device.
The deficiency of the utility model to solve above-mentioned technical problem, used technical solution is:
A kind of pre-screening double teeth roller crushing device, including crusher chamber, are arranged two breaker rolls in crusher chamber, breaker roll just under
Side is provided with broken beam；Power device drive two breaker roll relative rotation and and the cooperation of broken beam in crusher chamber to material into
Row crushing operation, the entrance of the crusher chamber extend outwardly one section of casing formed for adding materials, the side wall of crusher chamber
On be provided with spacing be equal to it is broken after material particular diameter sizing grill, sizing grill bottom is connected to discharge hole of crusher, screening
Grids top is arranged obliquely and least significant end extends to above breaker roll, and the maximum spacing between sizing grill and breaker roll is little
In being equipped with the drop guide for material diversion in the partial size of broken rear product, casing, drop guide end is being located at sizing grill just
Top is sieved in order to guide material in casing to sizing grill, and subsequent sizing grill draws the material of off grade size
It is directed in breaker roll and is crushed.
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 utility model are: the utility model is by increase casing and drop guide is added in casing, it will
Meet the material of pan feeding partial size through the drop guide pilot flow direction sizing grill in casing, the simultaneously greater than material of pan feeding partial size is kept off
On drop guide, reduce the probability that crusher blocks；Sizing grill carries out pre-screening to the material of entrance, avoids pairing
Unnecessary broken, the reduction coke breeze rate, the saving energy of lattice partial size material；Three teeth or four flute profile crushing teeths can keep pan feeding partial size with
Roller diameter is reduced while crushing force is constant, reduces installed power.

Fig. 2 is the top view of whole equipment in the utility model.
Fig. 3 is another arragement construction schematic diagram of the utility model.
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 in crusher chamber for the broken of broken material
Roller 2, breaker roll 2 use 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
Such as Fig. 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 is ability
Therefore the emphasis of the common knowledge of field technique personnel and not the application are not described in detail；Power device drives two to be crushed
2 relative rotation of roller and the cooperation of broken beam 1 carry out crushing operation to material in crusher chamber；Power device includes motor 6 and slows down
Device 7 drives two breaker rolls 2 to relatively rotate.The entrance of the crusher chamber extends outwardly one section of shield formed for adding materials
Cylinder 4；Spacing is provided on crusher chamber side wall as shown in Figure 1 can be using two equal to the sizing grill 3 of broken rear material particular diameter
Sizing grill 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 is located at the wherein side of breaker roll, while the other side of breaker roll is less than at a distance from crusher chamber side wall
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
