Description

A kind of mortar roller mill that revolves

Technical field

The utility model relates to a kind of milling equipment, especially relates to a kind of mortar roller mill that revolves.

Background technology

No. 94226079.1 disclosed roller mills of China's utility model patent, and it is existing not with the vertical roll grinder of pneumatic separation device, the same with ancient Raymond mill, all be bearing or bearing block with grinding roller, and the parts such as rackwork of their pin joint, grinding roller all are enclosed in the high again working chamber of dust from flying temperature, and environment is exceedingly odious.This makes routine safeguard, the necessary shutdown operation of work such as oiling and grinding roller positioning bothers time-consuming.Grinding roller bearing seal difficulty particularly, service life is short, and the equipment that makes can not turn round for a long time continuously.

The utility model content

The purpose of this utility model is to overcome the above-mentioned defective of existing vertical roll grinder, provides a kind of rational in infrastructure, and it is safe and reliable to turn round, and regular maintenances such as oiling, the adjustment of grinding roller position are convenient, do not need shut-down operation, the efficient energy-saving roller mill that running efficiency is high.

The purpose of this utility model is achieved through the following technical solutions: it comprises drive disk assembly (vee-pulley or bevel gear etc.), vertical pivot, roll the mortar dish, grinding roller, top cover, pressing spring, support, vertical pivot is installed on the support, and the grinding roller of original place rotation is distributed on and is fixed in rolling in the mortar dish working chamber on the vertical pivot during work; The bearing block of grinding roller is hingedly mounted on top cover top; The upper end of bearing block connects with screw mandrel by bearing pin, and the free end of described screw mandrel is supported on the bearing on top cover top; The positioning nut that pressing spring and spring pressure are adjusted nut and grinding roller all is contained on the screw mandrel; The top cover internal fixation a frustum-like shape steel plate sieve; Rolling mortar tries to get to the heart of a matter and is fixing scraper plate on the face; Discharge member (for example, load displacing screw or discharge chute) is equipped with in the support bottom.Equipment is vertically installed.

Mill feed material voluntarily by the grinding working face, is rushed at the steel plate sieve in the top cover by with after rolling centrifugal force that the mortar disc spins produced and evenly letting go voluntarily after milling in rolling the mortar dish, fine powder is discharged through sieve aperture, and excessive coarse grain is rebounded back to be rolled the mortar dish and reface.

The utility model removes and can be used as dry type or wet type fine grinding or pre-grinding, the use of also can connecting with dry ball or wet ball mill.Compare with ball mill or Raymond mill, its advantage is: (1) volume is little, the output height; (2) the specific yield power consumption hangs down 40-45% on year-on-year basis, and the steel consumption only is 5% of a ball milling; (3) occupation of land is little, needs tall and big factory building and roomy basis.

The utility model is not compared with the similar roller mill of pneumatic separation device with existing, advantage is: (1) material moves by centrifugal force in working chamber, material water ratio suitably improves rotating speed as required and can make the glutinous resistance of mobile component, even also can not result in blockage up to 5% greater than material; (2) both can be used for dry grinding, and also can be used as wet-milling, and existing roller mill can only be used for dry operation; (3) position of grinding roller bearing working mode and installation is reasonable, does not have the problem of difficult sealing, and can oil at any time, thereby long service life; (4) grinding roller positioning pressure regulation and add butter and need not stop; Safeguard simple and convenient, the running rate height; (5) bottom transmission, handling safety, even it is the machine of tearing open is changed the attrition component running part of also need not dismantling, time saving and energy saving; (6) product granularity is thin and even.

Accompanying drawing is the structural representation of the utility model one embodiment.

Among the figure, 1, vee-pulley; 2, vertical pivot; 3, roll the mortar dish; 4, grinding roller; 5, top cover; 6, grinding roller bearing block; 7, pressing spring; 8, steel plate sieve; 9, scraper plate; 10, support; 11, load displacing screw; 11 ₀The discharge chute; 12, screw mandrel; 13, grinding roller positioning nut; 14, spring pressure is adjusted nut; 15, horn shape bearing.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

With reference to accompanying drawing, present embodiment comprises vee-pulley 1, and vertical pivot 2 rolls mortar dish 3, grinding roller 4, top cover 5, pressing spring 7, support 10, vertical pivot 2 are installed on the support 10, and at least four grinding rollers 4 of original place rotation are arranged symmetrically in and are fixed in rolling in mortar dish 3 working chambers on the vertical pivot 2 during work; The bearing block 6 of grinding roller 4 is hingedly mounted on the top cover 5; The upper end of bearing block 6 connects with screw mandrel 12 by bearing pin; The free end of described screw mandrel 12 is supported on the horn shape bearing 15 on top cover 5 tops; The positioning nut 13 that pressing spring 7 and spring pressure are adjusted nut 14 and grinding roller 4 all is contained on the screw mandrel 12; Top cover 5 internal fixation a frustum-like shape steel plate sieve 8; Roll on mortar dish 3 bottom surfaces and fixing scraper plate 9; Load displacing screw 11 or discharge chute 11 are equipped with in support 10 bottoms ₀(according to the needs of production procedure linking, at load displacing screw 11 or discharge chute 11 ₀Select a kind of among both).

Material is given to by the centre bore of top cover 5 and rolls on the mortar dish 3, and material produces centrifugal force in the rotary course that rolls mortar dish 3, and evenly lets go rolling on mortar dish 3 bottom surfaces, repeatedly meets with grinding roller 4 in the process and is pulverized by rolling one by one being close to roll to scurry on mortar dish 3 skew walls; Thereafter, rush at steel plate sieve 8 by inertia, fine powder concentrates on load displacing screw 11 (or discharge chute 11 by sieve aperture through scraper plate 9 ₀) send, coarse granule is rebounded back by steel plate sieve 8 and rolls mortar dish 3 and reface.Grinding roller 4 and roll gap between mortar dish 3 inwalls and the size of spring 7 pressure decision product granularity can be adjusted nut 14 by grinding roller positioning nut 13 and spring pressure and be adjusted according to the product granularity requirement in the production.
