Abstract
The invention provides a wood grinder, belongs to the field of paper making machine preparation and aims to solve the problems that a pressure device of an existing wood grinder is complex in structure and high in energy consumption. The novel wood grinder comprises a cylindrical wood library, a millstone, a slurry pit, a spray pipe and a sharpening machine; the wood library is high in height, the height-diameter ratio is not less than 2, the wood grinder further comprises a conveyor belt for conducting feeding and an automatic feeding control system for conducting automatic feeding based on the log amount in the wood library, and the automatic feeding control system controls the conveyor belt; based on the above-mentioned structure, automatic log pressurizing is achieved, and meanwhile it is convenient to conduct continuous production.
Description
Technical field
The present invention relates to papermaking equipment apparatus field, be specifically related to a kind of mill.
Background technology
Mill ground wood principle is in the case of the grain of wood and grinding stone are axially in parallel, the timber of mill hopper is pressed to the grinding face rotated by impressed pressure (machinery or waterpower), owing to fiber is separated into single fiber by the rubbing action between grinding stone and timber, then sweep away pulping with water.
Existing mill, impressed pressure is machinery or waterpower, and wherein waterpower and some mechanical power pressurization mill can not be worked continuously, and i.e. enable and work continuously, and its structure is complicated, consumes big energy.
Summary of the invention
The technical problem to be solved is: the problem complicated for existing mill structure, energy resource consumption is big, the present invention provides a kind of novel mill, and it need not impressed pressure.
The technical solution used in the present invention is:
A kind of mill, including columned wood storehouse, grinding stone, slurry hole, sparge pipe and stone machine at quarter；Being told wood storehouse height high, its ratio of height to diameter is not less than 2, described mill also include for the conveyer belt of charging and based on log amount in wood storehouse automatically feed auto feed control system, described auto feed control system controls conveyer belt.
Further, in described slurry hole outlet, downflow weir is set, with frame for being flexibly connected bottom downflow weir.
Further, at described Mu Ku lower end and grinding stone gap, strip grate is set.
Further, described auto feed control system includes motor, controller, photoelectric sensor, and photoelectric sensor is arranged on specified altitude, and is connected with controller, controller switchs according to the signal control motor of photoelectric sensor, and driven by motor conveyer belt feeds.
The invention has the beneficial effects as follows: log pressuring method of the present invention uses self gravitation pressurization, and described a kind of mill, its ratio of height to diameter is big, it is adaptable to large-scale mill；When mill model is big, when diameter is the biggest with height value, the log self gravitation being subject to bottom grinding stone is the biggest, can substitute for external force pressurization；The reduction of the gravity simultaneously caused in order to avoid consuming during log defibrination, the present invention is provided with automatic feeding device, can be when log is reduced to certain altitude in wood storehouse, and auto feed keeps certain gravity.Meanwhile, the present invention is easy to produce continuously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of described a kind of mill；
In figure, 1-wood storehouse, 2-grinding stone, 3-starches hole, 4-sparge pipe, 5-strip grate, and 6-carves stone machine, 7-conveyer belt, 8-auto feed control system, 31-downflow weir, 81-motor, 82-controller, 83-photoelectric sensor.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in detail.
As it is shown in figure 1, a kind of mill, including columned wood storehouse 1, grinding stone 2, slurry hole 3, sparge pipe 4 and stone machine 6 at quarter；Being told wood storehouse 1 the highest, its ratio of height to diameter is not less than 2, and described mill also includes that described auto feed control system 8 controls conveyer belt 7 for the conveyer belt 7 of charging with based on log amount and automatically feed auto feed control system 8 in wood storehouse 1.
In described slurry hole 3 outlet, downflow weir 31 is set, with frame for being flexibly connected bottom downflow weir 31.
Described wood lower end, storehouse 1 arranges strip grate 5 at grinding stone 2 gap.
Described auto feed control system 8 includes motor 81, controller 82, photoelectric sensor 83, photoelectric sensor 83 is arranged on specified altitude, and be connected with controller 82, controller 82 switchs according to the signal control motor 81 of photoelectric sensor 83, and motor 81 drives conveyer belt 7 to feed.
During work, log is deposited into certain altitude in wood storehouse 1, and between log and grinding stone 2, pressure experienced is from the gravity of certain altitude log self；At this pressure, log rubs with grinding stone, and virgin fibers is stripped, and under the water impact of sparge pipe 4 ejection, is brought into slurry hole 3, thus completes slurrying.Constantly consuming when log and reduce, between bottom log and grinding stone 2, pressure also reduces, and reaches setting height, and photoelectric sensor 83 is monitored less than log, then be signaled to controller 82.Controller 82 controls motor 81 and starts, and controls conveyer belt 7 and feeds, it is ensured that the pressure between grinding stone 2 and log.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment and description; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements both fall within the range of claimed invention.Claimed scope is defined by appending claims and equivalent thereof.
