Abstract

The utility model discloses a rotary mortar pulverizer, which comprises a drive component, a vertical shaft, a rotary mortar disc, grinding rolls, a top cover, a pressing spring, and a seat. When in working, the self-rotating grinding rolls are evenly distributed on a working chamber of the rotary motor disc on the vertical shaft. A bearing seat of the grinding roll is arranged at the upper part of the top cover. The upper end of the bearing seat is connected with a screw rod by a pin shaft. The pressing spring, the spring pressure setting screw cap and the position adjusting screw cap of the grinding roll are arranged on the screw rod. A scraper is positioned on the bottom surface of the rotary mortar disc, and the inferior of the seat is provided with a discharging component. The utility model can be used as dry or wet type fine or advanced pulverizing. Moreover, after being perforated, the top cover can be used in series connection with either the negative pressure dry type powder concentrator, or the dry type or wet type ball mill. Compared with the ball mill or the Raymond mill, the utility model has the advantages of small volume and high yield. The electricity consumption of the utility model is reduced for 40 to 45%, and the steel consumption is only 5% of the ball mill. The water content of the material produced by the utility model, which has a small land occupation, is no less than 5%, and the jamming cannot be caused. The grinding roll bearing is provided with long service life. Moreover, the utility model has high running rate, fine and even product grain and relatively low manufacturing cost.

Description

Revolve the mortar flour mill

Technical field

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

Background technology

No. 94226079.1 disclosed flour mills of China's utility model patent, and existing most of vertical flour mills, 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.No. 200520050917.5 disclosed mortar roller mills that revolve of China's utility model patent, efficiently solve above-mentioned technical problem, but the indivedual places of its structural design still have careless omission to owe reasonable part, for example, the steel plate sieve of its top cover inside, softer when mill feed material, when not having corase particles in the material behind a grinding, it is unnecessary just to belong to.

The utility model content

The purpose of this utility model is to overcome existing above-mentioned defective of revolving the mortar rod mill, provides a kind of rational in infrastructure, and it is safe and reliable to turn round, regular maintenances such as oiling, the adjustment of grinding roller position are convenient, do not need shut-down operation, the running efficiency height is specially adapted to grinding and revolves the mortar flour mill than softer material.

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, revolve the mortar dish, grinding roller, pre-lid, pressing spring, support, vertical pivot is installed on the support, and the grinding roller of original place rotation is distributed in the working chamber that revolves the mortar dish that is fixed 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; Revolving mortar tries to get to the heart of a matter and is fixing scraper plate on the face; Discharge mechanism (for example, load displacing screw or discharge chute) is equipped with in the support bottom.Equipment is vertically installed.

Mill feed material arrives the grinding working chamber voluntarily by with revolving centrifugal force that the mortar disc spins produced revolving after the mortar tray bottom evenly lets go, and the material behind grinding is discharged by discharge mechanism by scraper plate.

On the top cover after the perforate, the use of can connecting with negative pressure dry type powder concentrator.

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 flour 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 the machine of tearing open change attrition component also need the row's of tearing open running part, time saving and energy saving; (6) product granularity is thin and even.

Compare with No. 200520050917.5 disclosed mortar roller mills that revolve of Chinese utility model patent, structure is more reasonable, has saved the frustum-like shape steel plate sieve of top cover inside, can reduce manufacturing cost.

Description of drawings

Fig. 1 is the structural representation of the utility model one embodiment.
