Abstract

The utility model aims to provide a chain mud scraper deviation correction device. The device comprises a PLC (Programmable Logic Controller), two sensors, induction slices fixed at two ends of a scraper blade, and an alarm, wherein the PLC is connected with the sensors and the alarm and is used for receiving scraper blade position data transmitted by the sensors so as to send a command to the alarm to control the shutdown of a chain mud scraper; the sensors are connected with the PLC and fixed on the wall of a mounting pond of the chain mud scraper and are used for acquiring the scraper blade position data and sending the data to the PLC; the induction slices fixed at two ends of the scraper blade are sensed by the sensors; the alarm is connected with the PLC and is used for receiving the command sent by the PLC and then giving an alarm. Preferably, the two sensors are adopted and are correspondingly arranged. The chain mud scraper and other equipment which are provided by the utility model have the advantages of chain deviation correction, automatic alarming, continuous operation, high efficiency, long service life, maintenance free and the like.

Description

Chain mud scraper deviation correcting device
Technical field
The utility model belongs to technical field of sewage treatment equipment, relates in particular to a kind of chain mud scraper deviation correcting device.
Background technology
Current, the equipment such as the chain mud scraper of horizontal sedimentation tank, due to reasons in structure, likely there will be faults such as jumping tooth, chain breakage.When there is above-mentioned fault, equipment itself cannot automatic sensing fault and quit work, and likely causes more parts to damage, and need to have personnel's timed patrol to find.
Summary of the invention
The purpose of this utility model is to provide a kind of chain mud scraper deviation correcting device, comprising: PLC controller, two sensors, the sensing chip that is fixed on scraper plate two ends, alarm,
Described PLC controller is connected with described sensor, described alarm, the scraper plate position data that described PLC controller sends for receiving sensor; To described alarm, send instruction; Controlling described chain mud scraper shuts down;
Described sensor is connected with described PLC controller, is fixed on chain mud scraper and installs on the wall in pond, and described sensor is for gathering the position data of scraper plate and sending to described PLC controller;
The described sensing chip that is fixed on scraper plate two ends for by described sensor senses;
Described alarm is connected with described PLC controller, after receiving the instruction that described PLC controller sends, reports to the police.
Preferably, described sensor is two, and setting position is corresponding.
Preferably, described alarm is voice guard and/or flash alarm.
The beneficial effects of the utility model are, the equipment such as the chain mud scraper that the utility model provides have chain correction, automatic alarm, operation continuously, high efficiency, long-life, the advantage such as non-maintaining.
Accompanying drawing explanation
Fig. 1 is structural representation a of the present utility model;
Fig. 2 is structural representation b of the present utility model;
In figure, 101-chain, 102-gear, 103-scraper plate, 201-fixation wall, 202-sensor, 203-sensing chip.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, below in conjunction with embodiment, the utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain the utility model, be not limited to protection domain of the present utility model.
As Fig. 1, shown in Fig. 2, a kind of embodiment of the present utility model is, power set can be motor, driven gear rotates, gear driven chain rotates, described chain is provided with a plurality of scraper plates, a plurality of scraper plates have interval, be arranged in parallel, on the word two side, pond that described chain mud scraper is installed, it is the fixation wall described in Fig. 2, be fixed with described sensor, the position of sensor is corresponding with chain place face, sensor can arrange two, be arranged at respectively in the fixation wall of both sides, pond, the two ends of all scraper plates are provided with sheet metal, described sheet metal can with sensor generation electromagnetic induction, sensor is connected with PLC controller.Described alarm is light and/or voice guard.
When in use, when equipment moves, sensor sensing is through the sheet metal on the scraper plate of its position, feedback signal is passed to Programmable Logic Controller, according to sensor probe, survey the spacing between different scraper plates, can be to be connected between two scraper plates, through the time of sensing point (installation of sensors position) and the process sensing point time difference at same scraper plate two ends, the running status of judgement scraper plate, and then judge whether chain is in normal operating condition, abnormal running state, can comprise, for example, when the time of the same sensing point of adjacent two scraper plates process is greater than Preset Time, there will be scraper plate to drop, flight pitch expands, when same scraper plate two ends have time difference or a time difference through the sensing point time, do not meet default time, can judge that scraper plate position has occurred and moved.When there is abnormal running state, PLC controller sends alarm command to alarm, and/or PLC controller is controlled described chain mud scraper shutdown.
The beneficial effects of the utility model are, the equipment such as the chain mud scraper that the utility model provides have chain correction, automatic alarm, operation continuously, high efficiency, long-life, the advantage such as non-maintaining.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some and retouching, these improvements and modifications also should be considered as protection domain of the present utility model.
