Abstract

The utility model relates to an observation sieve plate structure of a double-rotor crusher, which belongs to the technical field of crushers. The lower box body is positioned at two ends of the screen plate, and two sides of the screen plate are provided with double rotors. According to the utility model, the structure of the sieve plate is observed through the double-rotor crusher, so that the problem that the production capacity is reduced due to the fact that the gap between the sieve plate and the hammer head is influenced because the abrasion of the sieve plate cannot be observed is effectively avoided. Meanwhile, the whole opening of the shutdown maintenance time of the crusher is not needed, and a large amount of manpower and financial resources can be saved.

Description

Screen plate structure is observed to birotor breaker

Technical Field

The utility model belongs to the technical field of the breaker technique and specifically relates to a birotor breaker.

Background

The double-rotor crusher is the main equipment of crushing procedures in building materials, cement and mining industries, and the key main part is a screen plate arranged on a lower box body, wherein the larger a crushing cavity formed by the screen plate and a rotor in the double-rotor crusher is, the larger the crushing cavity is, the production capacity of the double-rotor crusher is affected. Once the gap is increased, only the screen plate abrasion can be checked for maintenance or replacement by stopping, thereby reducing the yield and bringing a great deal of financial effort. Therefore, the structure of the observation sieve plate of the double-rotor crusher has the advantages of convenience in observing the sieve plate, convenience in replacing the sieve plate and the like, so that the problem of waste yield caused by inspection and maintenance is solved, and meanwhile, a large amount of equipment cost and time cost are saved.

Disclosure of Invention

The utility model aims to solve the problems and provides a structure of an observation screen plate of a double-rotor crusher.

The utility model provides a birotor breaker observes sieve structure, includes lower box, sieve, hinge, observation door, bolt, nut, packing ring, observation hole constitution. In order to solve the device problem to be solved, the lower box body comprises a hinge, bolts, an observation door and nuts, wherein the lower box body is positioned at two ends of a sieve plate, and double rotors are arranged at two sides of the sieve plate; the observation hole is arranged in the middle of the lower box body and at the starting position of the sieve plate.

Further, a screen plate structure is observed to birotor breaker, the observation door is located the central symmetry setting in the middle of the box.

Further, a screen plate structure is observed to birotor breaker, birotor and screen plate set up in the inside of lower box.

Further, a dual rotor crusher observes the structure of the screen plate, the observation hole size is greater than the thickness of the screen plate.

Further, a screen plate structure is observed to birotor breaker, lower box and observation door pass through hinge swing joint.

The utility model has the beneficial effects that: the utility model adopts the observation hole to be arranged below the observation door and simultaneously arranges the observation hole at the position of the middle sieve plate, thereby reducing the yield problem of the double-rotor crusher caused by unclear sieve plate abrasion and reducing the labor cost and time energy of maintenance required by shutdown inspection.

Detailed Description

For a clearer understanding of technical features, objects, and effects of the present utility model, a specific embodiment of the present utility model will be described with reference to the accompanying drawings.

In this embodiment, in a structure of a screen plate for observation of a double-rotor crusher, as shown in fig. 1, an observation door 3 is attached to a lower case 1, the observation door 3 is controlled to be opened and closed by a nut 5, a washer 6 is used for dispersing pressure of the nut 5 to a connector of the observation door 3, and a bolt 4 is matched with the nut; when the nut 5 is unscrewed, the hinge 2 rotates to match with the opening of the observation door 3.

The observation door 3 of the lower chassis 1 is arranged at the center position and is used for observing the thicknesses of the two sides of the inner middle position sieve plate 7.

As shown in figure 2, the inner side of the structure device of the observation sieve plate of the double-rotor crusher is provided with the sieve plate 7, and the two sides of the structure device are provided with the observation doors 3, so that the two ends of the sieve plate 7 are convenient to observe.

As shown in fig. 3, the screen plate 7 is spaced between the double rotors 9 of the double rotor crusher, and the observation gate 3 is disposed outside the same position of the screen plate 7.

As shown in fig. 4, after the viewing door 3 is opened, the thickness and breakage of the screen plate 7 can be seen through the viewing holes 8, and the screen plate 7 is replaced after the wear reaches the limit.

According to the device, the wear condition and thickness of two sides of the rear screen plate can be observed in a central symmetry mode by setting up the structure of the screen plate observed by the double-rotor crusher, the thickness condition of two ends of the screen plate can be observed by the structure of the screen plate observed by the double-rotor crusher at two ends of the double-rotor crusher, the wear degree of the screen plate is directly observed at any time by using the observation holes without opening the crusher integrally, and the wear reaches the limit and is replaced by unpacking, so that the production capacity of the double-rotor crusher is influenced by the fact that the clearance between the screen plate and the rotor cannot be confirmed in traditional equipment is reduced, and the time cost for stopping and checking the screen plate due to the problem is reduced.

The foregoing has shown and described the basic principles and main features of the present utility model and the advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims. The scope of the utility model is defined by the appended claims and equivalents thereof.
