Abstract
The utility model relates to a control device of a filter press, in particular to a novel control device of the filter press, which solves the problems of lower reliability and higher failure rate of the pull-hook reverse control mode in the existing filter press. The novel control device of the filter press comprises an induction wheel and an approach switch, wherein the approach switch is opposite to the wheel face of the induction wheel; and a bump is fixed on the wheel face of the induction wheel. The novel control device of the filter press has simple structure and reasonable design, effectively solves the problems of lower reliability and higher failure rate of the pull-hook reverse control mode in the existing filter press and is applicable to controlling the filter press.
Description
Technical field
The utility model relates to the filter press control device, specifically is the novel control device of a kind of filter press.
Background technology
Filter press is a widely used dehydration equipment in the coal separation industry, mainly is made up of filter plate, pull hook etc.During work, hydraulic mechanism drives filter plate by pull hook and constantly moves back and forth, so pull hook commutation control is the core and the difficult point of filter press control always.At present, the main adopts pressure sensor of the pull hook of filter press commutation control detects the oil pressure of hydraulic pressure hold-down mechanism, when oil pressure is increased to certain value, triggers the commutation control circuit pull hook is commutated; The reliability of this kind control mode depends on many-sided factors such as adjustment of quality, sensitivity and the oil pressure of pressure sensor, thereby its reliability is lower, and fault rate is higher.Be necessary to invent a kind of new type pressure filter control device that can address the above problem for this reason.
Summary of the invention
The utility model provides a kind of filter press novel control device in order to solve the lower and fault rate problem of higher of existing filter press pull hook commutation control mode reliability.
The utility model is to adopt following technical scheme to realize: the novel control device of filter press comprises induction wheel and relative to the wheel face of induction wheel switch; Be fixed with projection on the wheel face of induction wheel.Described is existing known products near switch, can be buied by the market; The number of described projection is decided according to the actual requirements.
During work, the propeller shaft couplings of induction wheel and filter press is fixed, and near the commutation control circuit of switch access filter press, induction wheel rotates with the power transmission shaft of filter press, and the projection on the induction wheel rotates along wheel face; When projection goes to near the position of the switch relative (promptly going to the induction zone near switch) time, near switch output high level, otherwise, then near the switch output low level; Therefore, when power transmission shaft rotates, near switch output be square-wave signal, and when power transmission shaft does not change, what export near switch is single high level or low level signal; According to the signal waveform near switch output, the commutation control circuit can judge whether power transmission shaft rotates, and then realizes the commutation control to pull hook; Compare with existing filter press pull hook commutation control mode, the novel control device of filter press described in the utility model need not connect with the oil circuit of hydraulic pressure hold-down mechanism, thereby it is less to influence the factor of its reliability, and its fault rate is lower.
The utility model is simple in structure, reasonable in design, efficiently solves the lower and fault rate problem of higher of existing filter press pull hook commutation control mode reliability, is applicable to filter press control.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
