Abstract

The invention relates to a cement container complete-circle unidirectional rotation and non-complete-circle bidirectional rotation allocation running method, and belongs to the field of measurement and control technologies. The method provided by the invention comprises the steps of firstly calculating all values of the number of complete-circle unidirectional rotation times, then calculating the number of complete-circle unidirectional rotation times according a principle that the difference between the number of complete-circle unidirectional rotation times and the number of non-complete-circle bidirectional rotation times is the smallest, thus respectively determining the number of complete-circle unidirectional rotation times, the number of non-complete-circle bidirectional rotation times and a rotating angle, and finally arranging complete-circle unidirectional rotation and non-complete-circle bidirectional rotation so as to acquire a specific result of the allocation running method. According to the invention, a technology prejudice that a cement container can only perform complete-circle unidirectional rotation to carry out stirring is overcome, and a specific allocation running method of complete-circle unidirectional rotation and non-complete-circle bidirectional rotation is further provided on the basis of introducing the running mode of non-complete-circle bidirectional rotation and combining complete-circle unidirectional rotation and non-complete-circle bidirectional rotation.

Description

A kind of cementing tank complete cycle one-directional rotation distributes operation method with non-complete cycle Double-directional rotary

Technical field

Cementing tank complete cycle one-directional rotation of the present invention belongs to observation and control technology field with non-complete cycle Double-directional rotary distribution operation method.

Background technology

Bulk cement carrier has automatic stirring cement, the function of the cement that comes down in torrents, owing to a large amount of packaging material and handling labor can be saved, Therefore irreplaceable effect is played in building trade.

Using the simplest cementing tank method of operation on bulk cement carrier is that cementing tank persistently carries out complete cycle one-directional rotation, and this mode is transported Row gets up very simple, but, cement is the most continuously stirred in the case of mixed uniformly, can waste drive energy.

The problem solving drive energy waste, has following two means:

The first, reducing the rotating speed of cementing tank, although this mode reduces the number of revolutions of cementing tank, but cementing tank is at a slow speed In the case of rotation, drive efficiency reduce, cementing tank run one week required for drive energy add again, therefore save driving The effect of the energy is limited；

The second, cementing tank rotates and static alternately this mode also can reduce the number of revolutions of cementing tank, but cementing tank In the stationary case, the stone that proportion is bigger can gradually sink to bottom, causes cement to owe uniformly, the when of again driving, needs Driving energy that will be bigger, the effect therefore saving drive energy is the most notable.

For the problems referred to above, applicant have submitted a patent of invention " a kind of cementing tank stirring operation method " on the same day, overcomes water Mud tank can only the technology prejudice that is stirred of complete cycle one-directional rotation, introduce the method for operation of non-complete cycle Double-directional rotary, and by complete cycle list Combine with non-complete cycle Double-directional rotary to rotating, reached to save the technique effect of drive energy.But, complete cycle one-directional rotation with The most non-complete cycle Double-directional rotary distributes, and does not disclose in that patent.

Summary of the invention

For the problems referred to above, the invention discloses a kind of cementing tank complete cycle one-directional rotation and distribute operation method with non-complete cycle Double-directional rotary, This method give complete cycle one-directional rotation and non-complete cycle Double-directional rotary specifically distributes operation method.

The object of the present invention is achieved like this:

A kind of cementing tank complete cycle one-directional rotation and non-complete cycle Double-directional rotary distribute operation method, definition:

α is within a segmentation cycle, the total angle of rotation of cementing tank；

T is the time in a segmentation cycle；

M is the number of times of complete cycle one-directional rotation；

t₁And t₂It is respectively time and the time of non-complete cycle Double-directional rotary of complete cycle one-directional rotation, and t₁＞ t₂；

The corner threshold value of cementing tank when β is to come down in torrents cement；

Comprise the following steps:

Step a, it is calculated as follows method:

$\frac{(\mathrm{\α}-m\·2\mathrm{\π})\·t_2}{T-m\·t_1}\≤2\mathrm{\β}$

It is met all values of the m of above formula condition；

Step b, it is calculated as follows method:

$a=m-\frac{T-m\·t_1}{t_2}$

Obtain when a is m value during minimum；

Step c, determine the complete cycle one-directional rotation including that m corner is 2 π, andIndividual corner is's Non-complete cycle Double-directional rotary；

Step d, complete cycle one-directional rotation and non-complete cycle Double-directional rotary are arranged

If m withEqual, then complete cycle one-directional rotation is alternately arranged with non-complete cycle Double-directional rotary, and sequencing is random；

If m is more thanTakeIndividual complete cycle one-directional rotation is alternately arranged with non-complete cycle Double-directional rotary, the most suitable Sequence is random, by remainingIndividual complete cycle one-directional rotation is inserted into the optional position of rank results；

If m is less thanTaking m non-complete cycle Double-directional rotary alternately arranged with complete cycle one-directional rotation, sequencing is random, By remainingIndividual non-complete cycle Double-directional rotary is inserted into the optional position of rank results.

Above-mentioned cementing tank complete cycle one-directional rotation and non-complete cycle Double-directional rotary distribute operation method, omit step b, directly execution step a, Step c and step d.

Beneficial effect:

The first, instant invention overcomes cementing tank can only the technology prejudice that is stirred of complete cycle one-directional rotation, introducing, non-complete cycle is two-way The method of operation rotated, and on the basis of complete cycle one-directional rotation being combined with non-complete cycle Double-directional rotary, furthermore present complete cycle One-directional rotation specifically distributes operation method with non-complete cycle Double-directional rotary；

The second, due to the number of times according to complete cycle one-directional rotation Yu non-complete cycle Double-directional rotary, identical part is selected alternately, because of It is oversize that this is avoided non-complete cycle Double-directional rotary to run the time, the similar static problem occurred when driving again occurs.
