In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "communicating" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; they may be mechanically or electrically connected, directly or indirectly through intervening media, or both elements may be in communication. The specific meaning of the above terms in the present invention can be understood as a specific case by those skilled in the art.
The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
The device for controlling the running length of the filter cloth of the belt filter comprises a PLC (programmable logic controller), wherein a rotating shaft 3 is arranged on a frame 100 of the belt filter above a filter cloth bend roller 6, the rotating shaft 3 is fixedly connected with a fixing frame 5, an encoder 4 is fixedly arranged on the fixing frame 5, a friction rotating wheel 2 is fixedly connected on an input shaft of the encoder 4, the friction rotating wheel 2 is abutted against the filter cloth 1 on the filter cloth bend roller 6 under the action of the friction rotating wheel 2 and the weight of the encoder, and the encoder 4 is electrically connected with the PLC. The encoder 4 is of an incremental, shaft type.
An encoder is a device that compiles, converts, and formats signals, such as bitstreams or data, into a form of signals that can be used for communication, transmission, and storage. Encoders convert angular or linear displacements, called codewheels, into electrical signals, called coderulers. The incremental encoder converts displacement into periodic electrical signals, and then converts the electrical signals into counting pulses, and the number of the pulses is used for expressing the magnitude of the displacement.
In another preferred embodiment, the rotating shaft 3 is sleeved with a torsion spring, one end of the torsion spring is abutted with the fixing frame 5, and the other end of the torsion spring is abutted with the belt filter frame 100, so that the slipping of the friction rotating wheel 2 caused by insufficient abutting pressure due to pure gravity can be effectively avoided, and the metering is inaccurate.
In another preferred embodiment, the friction wheel 2 has a diameter which is larger than the diameter of the housing of the encoder 4. This can avoid interference of the encoder 4 with the filter cloth.
In another preferred embodiment, a rubber ring is fixed on the circumferential surface of the friction rotating wheel 2, or the circumferential surface of the friction rotating wheel 2 is provided with a reticulation or a straight knurling. By adopting the two modes, the friction force between the friction rotating wheel 2 and the filter cloth can be increased, and the friction rotating wheel 2 is prevented from slipping, so that inaccurate metering is caused.
The rotating shaft 3 is arranged on the belt filter frame 100 above the filter cloth redirection roller 6 in a rotating mode, the rotating shaft 3 is fixedly connected with the fixing frame 5, the encoder 4 is fixedly arranged on the fixing frame 5, the rotating shaft 3 is located above the filter cloth redirection roller 6 and forms a spiral arm structure with the rotating shaft 3 fixedly connected with the fixing frame 5, the friction rotating wheel 2 is abutted to the filter cloth 1 under the action of gravity or a torsion spring, the friction rotating wheel 2 abutted to the filter cloth 1 rotates along with the filter cloth 1 in the operation process of the filter cloth 1, the rotation of the friction rotating wheel 2 drives the code wheel of the encoder to rotate, the angular displacement of the code wheel is converted into a periodic electric signal by the encoder, the electric signal is converted into a counting pulse, the PLC can calculate the operation length of the filter cloth according to the received counting pulse and the diameter data of the preset friction rotating wheel, and therefore real-time control is carried out, and the filter cloth is controlled to stop operating if the set operation length is reached.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of this invention without departing from the spirit thereof.
