Abstract

The utility model relates to a dry-method roll-in granulator which comprises a rack, two groups of bearing bases and two main compression rollers, wherein the two groups of bearing bases are arranged on the rack; the two main compression rollers are arranged into one corresponding bearing base; the upper ends or the lower ends of the two groups of bearing bases or one group of the bearing bases are hinged with the rack; and the other ends, opposite to the hinging ends, of the two bearing bases are connected through a hydraulic cylinder. According to the dry-method roll-in granulator, the main compression roller adopts a swinging movement mode, so that the jump of the compression roller is prevented; and meanwhile the gap between two main compression rollers is controlled by the hydraulic cylinder with high precision, so that the material is prevented from being crushed down, the yield, hardness and richness of the product are increased, and the quality in granulation is stable; the bearing bases can be laid horizontally like a hinge, so that the space at the side plane is increased effectively; the components such as the sealing plates at two sides of the compression rollers and the bearings can be maintained and repaired conveniently, so that a great deal of labor, material resources and time are saved; and the dry-method roll-in granulator is smart and reasonable in structure design and has a higher practicability, and the production efficiency is improved greatly.

Description

The dry method rolling comminutor

Technical field

The utility model relates to a kind of Granulation Equipments, particularly a kind of dry method rolling comminutor.

Background technology

The dry method rolling comminutor is of many uses in industries such as fertilizer, chemical industry, medicine, breeze, metallurgy, makes raw material be convenient to transportation, and the pollution that controls environment improves workman's work working condition.

The dry method rolling comminutor generally has hopper, vertical feeding auger and two main pressure rollers, and semi-circular arc groove that the even distribution shape of main roller surface is identical or rhombus groove through the transmission of special-purpose lose-lose reductor, make two pressure roller constant speed, reverse rotation.Granular material adds material bin quantitatively, equably during work; Make and keep constant material level in the hopper; By the vertical feeding auger in the hopper powder is carried out precompressed then and contract and be delivered to the arc-shaped slot of two pressure rollers, two main pressure rollers are with the material moment enforce compression material of nipping in the groove, and material comes off in groove after compression molding; Get into broken dying grain system; Then according to user's granularity requirements sieve, classification, the single-size product that obtains conforming to quality requirements, the sieve under powder return the hopper ringing again.

The main pressure roller of existing dry method rolling comminutor generally is divided into level pressure roller and dynamic pressure roller; Dynamic pressure roller is arranged on the bearing block, and bearing block is movably arranged on the frame, owing to need to regulate the gap of two main pressure rollers; And work such as replacing of equipment, maintenance, maintenance; Therefore bearing block generally all is to be arranged on the frame through adjustable the moving of thread mechanism, therefore between bearing block and frame, is easy to generate bigger gap, makes pressure roller when work, can produce and beats; The sheet material of press forming is beated because of pressure roller has part to be pulverized, and influences output and hardness, the full grains degree of finished product; Owing to the sealing plate easy abrasion of main pressure roller side, need periodic replacement simultaneously, existing equipment needs more manpower and the time to operate, very inconvenience of part exchanging, plant maintenance, maintenance.

The utility model content

The purpose of the utility model provides a kind of above-mentioned shortcoming that overcomes, and granulation steady quality, maintaining be the dry method rolling comminutor easily.

The technical scheme that realizes the utility model purpose is: a kind of dry method rolling comminutor, have frame, two groups of bearing blocks and two main pressure rollers, and two groups of bearing blocks are arranged on the frame, and two main pressure rollers are arranged in corresponding one group of bearing block; The upper end of said two groups of bearing blocks or one group of bearing block or lower end and frame are hinged, and the other end of two relative hinged ends of bearing block connects through hydraulic jack.

The hydraulic jack of above-mentioned dry method rolling comminutor is fixedly installed on the frame, and the lower end of two groups of bearing blocks is hinged with frame respectively, and the upper end of two groups of bearing blocks connects through hydraulic jack.

The hydraulic jack of above-mentioned dry method rolling comminutor is fixedly installed on the frame, and the lower end and the frame of one group of bearing block are hinged, and another group bearing block is fixedly connected with frame, and the upper end of two groups of bearing blocks connects through hydraulic jack.

The bearing block of above-mentioned dry method rolling comminutor is connected through bearing pin with hydraulic jack.

The utlity model has positive effect: the motion mode of (1) the utility model master pressure roller adopts swing type; So eliminated beating of pressure roller; Gap between while two main pressure rollers relies on hydraulic jack control, and precision is higher, has avoided material to be pulverized; Increase output, hardness and the plumpness of finished product, the granulation steady quality; (2) the utility model bearing block can keep flat as hinge, has effectively strengthened the space of equipment side, to parts such as pressure roller, bearing both sides sealing plate maintenance, safeguard very conveniently, has saved great amount of manpower and material resources and time; (3) the utility model structural design is ingenious rationally, and production efficiency improves significantly, has advantages of high practicability.
